   114.00 Immune System Disorders
   
   A. What disorders do we evaluate under the immune system disorders
         listings?
   
   1. We evaluate immune system disorders that cause dysfunction in one or more
         components of your immune system.
   
   a. The dysfunction may be due to problems in antibody production, impaired cell-mediated
      immunity, a combined type of antibody/cellular deficiency, impaired phagocytosis,
      or complement deficiency.
   
   
   b. Immune system disorders may result in recurrent and unusual infections, or inflammation
      and dysfunction of the body's own tissues. Immune system disorders can cause a deficit
      in a single organ or body system that results in extreme (that is, very serious) loss
      of function. They can also cause lesser degrees of limitations in two or more organs
      or body systems, and when associated with symptoms or signs, such as severe fatigue,
      fever, malaise, diffuse musculoskeletal pain, or involuntary weight loss, can also
      result in extreme limitation. In children, immune system disorders or their treatment
      may also affect growth, development, and the performance of age-appropriate activities.
   
   
   c. We organize the discussions of immune system disorders in three categories: Autoimmune
      disorders; Immune deficiency disorders, excluding human immunodeficiency virus (HIV)
      infection; and HIV infection.
   
   
   2. Autoimmune disorders (114.00D). Autoimmune disorders are caused by dysfunctional immune responses directed against
      the body's own tissues, resulting in chronic, multisystem impairments that differ
      in clinical manifestations, course, and outcome. They are sometimes referred to as
      rheumatic diseases, connective tissue disorders, or collagen vascular disorders. Some
      of the features of autoimmune disorders in children differ from the features of the
      same disorders in adults. The impact of the disorders or their treatment on physical,
      psychological, and developmental growth of pre-pubertal children may be considerable,
      and often differs from that of post-pubertal adolescents or adults.
   
   
   3. Immune deficiency disorders, excluding HIV infection (114.00E). Immune deficiency disorders are characterized by recurrent or unusual infections
      that respond poorly to treatment, and are often associated with complications affecting
      other parts of the body. Immune deficiency disorders are classified as either primary (congenital) or acquired. Children with immune deficiency disorders also have an increased risk of malignancies
      and of having autoimmune disorders.
   
   
   4. Human immunodeficiency virus (HIV) infection (114.00F). HIV infection may be characterized by increased susceptibility to common infections
      as well as opportunistic infections, cancers, or other conditions listed in 114.11.
   
   
   B. What information do we need to show that you have an immune system
         disorder?
   
   Generally, we need your medical history, a report(s) of a physical examination, a
      report(s) of laboratory findings, and in some instances, appropriate medically acceptable
      imaging or tissue biopsy reports to show that you have an immune system disorder.
      Therefore, we will make every reasonable effort to obtain your medical history, medical
      findings, and results of laboratory tests. We explain the information we need in more
      detail in the sections below.
   
   
   C. Definitions
   
   1. Appropriate medically acceptable imaging includes, but is not limited to, angiography, x-ray imaging, computerized axial tomography
      (CAT scan) or magnetic resonance imaging (MRI), with or without contrast material,
      myelography, and radionuclear bone scans. "Appropriate" means that the technique used
      is the proper one to support the evaluation and diagnosis of the impairment.
   
   
   2. Constitutional symptoms or signs, as used in these listings, means severe fatigue, fever, malaise, or involuntary weight
      loss. Severe fatigue means a frequent sense of exhaustion that results in significantly reduced physical
      activity or mental function. Malaise means frequent feelings of illness, bodily discomfort, or lack of well-being that
      result in significantly reduced physical activity or mental function.
   
   
   3. Disseminated means that a condition is spread over a considerable area. The type and extent of
      the spread will depend on your specific disease.
   
   
   4. Dysfunction means that one or more of the body regulatory mechanisms are impaired, causing either
      an excess or deficiency of immunocompetent cells or their products.
   
   
   5. Extra-articular means "other than the joints"; for example, an organ(s) such as the heart, lungs,
      kidneys, or skin.
   
   
   6. Documented medical need has the same meaning as in 101.00C6a.
   
   
   7. Fine and gross movements has the same meaning as in 101.00E4.
   
   
   8. Major joint of an upper or a lower extremity has the same meaning as in 101.00I2 and 101.00I3.
   
   
   9. Persistent means that a sign(s) or symptom(s) has continued over time. The precise meaning will
      depend on the specific immune system disorder, the usual course of the disorder, and
      the other circumstances of your clinical course.
   
   
   10. Recurrent means that a condition that previously responded adequately to an appropriate course
      of treatment returns after a period of remission or regression. The precise meaning,
      such as the extent of response or remission and the time periods involved, will depend
      on the specific disease or condition you have, the body system affected, the usual
      course of the disorder and its treatment, and the other facts of your particular case.
   
   
   11. Resistant to treatment means that a condition did not respond adequately to an appropriate course of treatment.
      Whether a response is adequate or a course of treatment is appropriate will depend
      on the specific disease or condition you have, the body system affected, the usual
      course of the disorder and its treatment, and the other facts of your particular case.
   
   
   12. Severe means medical severity as used by the medical community. The term does not have the
      same meaning as it does when we use it in connection with a finding at the second
      step of the sequential evaluation process in § 416.920 of this chapter.
   
   
   D. How do we document and evaluate the listed autoimmune disorders?
   
   1. Systemic lupus erythematosus (114.02).
   
   a. General. Systemic lupus erythematosus (SLE) is a chronic inflammatory disease that can affect
      any organ or body system. It is frequently, but not always, accompanied by constitutional
      symptoms or signs (severe fatigue, fever, malaise, involuntary weight loss). Major
      organ or body system involvement can include: Respiratory (pleuritis, pneumonitis),
      cardiovascular (endocarditis, myocarditis, pericarditis, vasculitis), renal (glomerulonephritis),
      hematologic (anemia, leukopenia, thrombocytopenia), skin (photosensitivity), neurologic
      (seizures), mental (anxiety, fluctuating cognition ("lupus fog"), mood disorders,
      organic brain syndrome, psychosis), or immune system disorders (inflammatory arthritis).
      Immunologically, there is an array of circulating serum auto-antibodies and pro- and
      anti-coagulant proteins that may occur in a highly variable pattern.
   
   
   b. Documentation of SLE. Generally, but not always, the medical evidence will show that your SLE satisfies
      the criteria in the current "Criteria for the Classification of Systemic Lupus Erythematosus"
      by the American College of Rheumatology found in the most recent edition of the "Primer
      on the Rheumatic Diseases" published by the Arthritis Foundation.
   
   
   2. Systemic vasculitis (114.03).
   
   a. General.
   
   (i) Vasculitis is an inflammation of blood vessels. It may occur acutely in association
      with adverse drug reactions, certain chronic infections, and occasionally, malignancies.
      More often, it is chronic and the cause is unknown. Symptoms vary depending on which
      blood vessels are involved. Systemic vasculitis may also be associated with other
      autoimmune disorders; for example, SLE or dermatomyositis.
   
   
   (ii) Children can develop the vasculitis of Kawasaki disease, of which the most serious
      manifestation is formation of coronary artery aneurysms and related complications.
      We evaluate heart problems related to Kawasaki disease under the criteria in the cardiovascular
      listings (104.00). Children can also develop the vasculitis of anaphylactoid purpura
      (Henoch-Schoenlein purpura), which may cause intestinal and renal disorders. We evaluate
      intestinal and renal disorders related to vasculitis of anaphylactoid purpura under
      the criteria in the digestive (105.00) or genitourinary (106.00) listings. Other clinical
      patterns include, but are not limited to, polyarteritis nodosa, Takayasu's arteritis
      (aortic arch arteritis), and Wegener's granulomatosis.
   
   
   b. Documentation of systemic vasculitis. Angiography or tissue biopsy confirms a diagnosis of systemic vasculitis when the
      disease is suspected clinically. When you have had angiography or tissue biopsy for
      systemic vasculitis, we will make every reasonable effort to obtain reports of the
      results of that procedure. However, we will not purchase angiography or tissue biopsy.
   
   
   3. Systemic sclerosis (scleroderma) (114.04).
   
   a. General. Systemic sclerosis (scleroderma) constitutes a spectrum of disease in which thickening
      of the skin is the clinical hallmark. Raynaud's phenomenon, often medically severe
      and progressive, is present frequently and may be the peripheral manifestation of
      a vasospastic abnormality in the heart, lungs, and kidneys. The CREST syndrome (calcinosis,
      Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) is
      a variant that may slowly progress over years to the generalized process, systemic
      sclerosis.
   
   
   b. Diffuse cutaneous systemic sclerosis. In diffuse cutaneous systemic sclerosis (also known as diffuse scleroderma), major
      organ or systemic involvement can include the gastrointestinal tract, lungs, heart,
      kidneys, and muscle in addition to skin or blood vessels. Although arthritis can occur,
      joint dysfunction results primarily from soft tissue/cutaneous thickening, fibrosis,
      and contractures.
   
   
   c. Localized scleroderma (linear scleroderma and morphea).
   
   (i) Localized scleroderma (linear scleroderma and morphea) is more common in children
      than systemic scleroderma. To assess the severity of the impairment, we need a description
      of the extent of involvement of linear scleroderma and the location of the lesions.
      For example, linear scleroderma involving the arm but not crossing any joints is not
      as functionally limiting as sclerodactyly (scleroderma localized to the fingers).
      Linear scleroderma of a lower extremity involving skin thickening and atrophy of underlying
      muscle or bone can result in contractures and leg length discrepancy. In such cases,
      we may evaluate your impairment under the musculoskeletal listings (101.00).
   
   
   (ii) When there is isolated morphea of the face causing facial disfigurement from
      unilateral hypoplasia of the mandible, maxilla, zygoma, or orbit, adjudication may
      be more appropriate under the criteria in the affected body system, such as special
      senses and speech (102.00) or mental disorders (112.00).
   
   
   (iii) Chronic variants of these syndromes include disseminated morphea, Shulman's
      disease (diffuse fasciitis with eosinophilia), and eosinophilia-myalgia syndrome (often
      associated with toxins such as toxic oil or contaminated tryptophan), all of which
      can impose medically severe musculoskeletal dysfunction and may also lead to restrictive
      pulmonary disease. We evaluate these variants of the disease under the criteria in
      the musculoskeletal listings (101.00) or respiratory system listings (103.00).
   
   
   d. Documentation of systemic sclerosis (scleroderma). Documentation involves differentiating the clinical features of systemic sclerosis
      (scleroderma) from other autoimmune disorders. However, there may be an overlap.
   
   4. Polymyositis and dermatomyositis (114.05).
   
   a. General.
   
   (i) Polymyositis and dermatomyositis are related disorders that are characterized
      by an inflammatory process in striated muscle, occurring alone or in association with
      other autoimmune disorders. The most common manifestations are symmetric weakness,
      and less frequently, pain and tenderness of the proximal limb-girdle (shoulder or
      pelvic) musculature. There may also be involvement of the cervical, cricopharyngeal,
      esophageal, intercostal, and diaphragmatic muscles.
   
   
   (ii) Polymyositis occurs rarely in children; the more common presentation in children
      is dermatomyositis with symmetric proximal muscle weakness and characteristic skin
      findings. The clinical course of dermatomyositis can be more severe when it is accompanied
      by systemic vasculitis rather than just localized to striated muscle. Late in the
      disease, some children with dermatomyositis develop calcinosis of the skin and subcutaneous
      tissues, muscles, and joints. We evaluate the involvement of other organs/body systems
      under the criteria for the listings in the affected body system.
   
   
   b. Documentation of polymyositis and dermatomyositis. Generally, but not always, polymyositis is associated with elevated serum muscle
      enzymes (creatine phosphokinase (CPK), aminotransferases, and aldolase), and characteristic
      abnormalities on electromyography and muscle biopsy. In children, the diagnosis of
      dermatomyositis is supported largely by medical history, findings on physical examination
      that include the characteristic skin findings, and elevated serum muscle enzymes.
      Muscle inflammation or vasculitis depicted on MRI is additional evidence supporting
      the diagnosis of childhood dermatomyositis. When you have had electromyography, muscle
      biopsy, or MRI for polymyositis or dermatomyositis, we will make every reasonable
      effort to obtain reports of the results of that procedure. However, we will not purchase
      electromyography, muscle biopsy, or MRI.
   
   
   c. Additional information about how we evaluate polymyositis and dermatomyositis
         under the listings. 
   
   (i) In newborn and younger infants (birth to attainment of age 1), we consider muscle
      weakness that affects motor skills, such as head control, reaching, grasping, taking
      solids, or self-feeding, under 114.05A. In older infants and toddlers (age 1 to attainment
      of age 3), we also consider muscle weakness affecting your ability to roll over, sit,
      crawl, or walk under 114.05A.
   
   
   (ii) If you are of preschool age through adolescence (age 3 to attainment of age 18),
      weakness of your pelvic girdle muscles that results in your inability to rise independently
      from a squatting or sitting position or to climb stairs may be an indication that
      you are unable to walk without assistance. Weakness of your shoulder girdle muscles
      may result in your inability to perform lifting, carrying, and reaching overhead,
      and also may seriously affect your ability to perform activities requiring fine movements.
      We evaluate these limitations under 114.05A.
   
   
   5. Undifferentiated and mixed connective tissue disease (114.06).
   
   a. General. This listing includes syndromes with clinical and immunologic features of several
      autoimmune disorders, but which do not satisfy the criteria for any of the specific
      disorders described. For example, you may have clinical features of SLE and systemic
      vasculitis, and the serologic (blood test) findings of rheumatoid arthritis. The most
      common pattern of undifferentiated autoimmune disorders in children is mixed connective
      tissue disease (MCTD).
   
   
   b. Documentation of undifferentiated and mixed connective tissue disease. Undifferentiated connective tissue disease is diagnosed when clinical features and
      serologic (blood test) findings, such as rheumatoid factor or antinuclear antibody
      (consistent with an autoimmune disorder) are present but do not satisfy the criteria
      for a specific disease. Children with MCTD have laboratory findings of extremely high
      antibody titers to extractable nuclear antigen (ENA) or ribonucleoprotein (RNP) without
      high titers of anti-dsDNA or anti-SM antibodies. There are often clinical findings
      suggestive of SLE or childhood dermatomyositis. Many children later develop features
      of scleroderma.
   
   
   6. Inflammatory arthritis (114.09).
   
   a. General. The spectrum of inflammatory arthritis includes a vast array of disorders that differ
      in cause, course, and outcome. Clinically, inflammation of major joints in an upper
      or a lower extremity may be the dominant manifestation causing difficulties with walking
      or fine and gross movements; there may be joint pain, swelling, and tenderness. The
      arthritis may affect other joints, or cause less limitation in walking or fine and
      gross movements. However, in combination with extra-articular features, including
      constitutional symptoms or signs (severe fatigue, fever, malaise, and involuntary
      weight loss), inflammatory arthritis may result in an extreme limitation.
   
   
   b. Inflammatory arthritis involving the axial spine (spondyloarthropathy). In children, inflammatory arthritis involving the axial spine may be associated with
      disorders such as:
   
   
   (i) Reactive arthropathies;
   
   (ii) Juvenile ankylosing spondylitis;
   
   (iii) Psoriatic arthritis;
   
   (iv) SEA syndrome (seronegative enthesopathy arthropathy syndrome);
   
   (v) Behçet's disease; and
   
   (vi) Inflammatory bowel disease.
   
   c. Inflammatory arthritis involving the peripheral joints. In children, inflammatory arthritis involving peripheral joints may be associated
      with disorders such as:
   
   
   (i) Juvenile rheumatoid arthritis;
   
   (ii) Sjögren's syndrome;
   
   (iii) Psoriatic arthritis;
   
   (iv) Crystal deposition disorders (gout and pseudogout);
   
   (v) Lyme disease; and
   
   (vi) Inflammatory bowel disease.
   
   d. Documentation of inflammatory arthritis. Generally, but not always, the diagnosis of inflammatory arthritis is based on the
      clinical features and serologic findings described in the most recent edition of the
      "Primer on the Rheumatic Diseases" published by the Arthritis Foundation.
   
   
   e. How we evaluate inflammatory arthritis under the listings.
   
   (i) Listing-level severity in 114.09A and 114.09C1 is shown by the presence of an
      impairment-related physical limitation of functioning. In 114.09C1, if you have the
      required ankylosis (fixation) of your cervical or dorsolumbar spine, we will find
      that you have a listing-level impairment-related physical limitation in your ability
      to see in front of you, above you, and to the side, even though you might not require
      bilateral upper limb assistance.
   
   
   (ii) Listing-level severity in 114.09B and 114.09C2 is shown by inflammatory arthritis
      that involves various combinations of complications (such as inflammation or deformity,
      extra-articular features, repeated manifestations, and constitutional symptoms and
      signs) of one or more major joints in an upper or a lower extremity (see 114.00C8)
      or other joints. Extra-articular impairments may also meet listings in other body
      systems.
   
   
   (iii) Extra-articular features of inflammatory arthritis may involve any body system;
      for example: Musculoskeletal (heel enthesopathy), ophthalmologic (iridocyclitis, keratoconjunctivitis
      sicca, uveitis), pulmonary (pleuritis, pulmonary fibrosis or nodules, restrictive
      lung disease), cardiovascular (aortic valve insufficiency, arrhythmias, coronary arteritis,
      myocarditis, pericarditis, Raynaud's phenomenon, systemic vasculitis), renal (amyloidosis
      of the kidney), hematologic (chronic anemia, thrombocytopenia), neurologic (peripheral
      neuropathy, radiculopathy, spinal cord or cauda equina compression with sensory and
      motor loss), mental (cognitive dysfunction, poor memory), and immune system (Felty's
      syndrome (hypersplenism with compromised immune competence)).
   
   
   (iv) If both inflammation and chronic deformities are present, we evaluate your impairment
      under the criteria of any appropriate listing.
   
   
   7. Sjögren's syndrome (114.10).
   
   a. General.
   
   (i) Sjögren's syndrome is an immune-mediated disorder of the exocrine glands. Involvement
      of the lacrimal and salivary glands is the hallmark feature, resulting in symptoms
      of dry eyes and dry mouth, and possible complications, such as corneal damage, blepharitis
      (eyelid inflammation), dysphagia (difficulty in swallowing), dental caries, and the
      inability to speak for extended periods of time. Involvement of the exocrine glands
      of the upper airways may result in persistent dry cough.
   
   
   (ii) Many other organ systems may be involved, including musculoskeletal (arthritis,
      myositis), respiratory (interstitial fibrosis), gastrointestinal (dysmotility, dysphagia,
      involuntary weight loss), genitourinary (interstitial cystitis, renal tubular acidosis),
      skin (purpura, vasculitis,), neurologic (central nervous system disorders, cranial
      and peripheral neuropathies), mental (cognitive dysfunction, poor memory), and neoplastic
      (lymphoma). Severe fatigue and malaise are frequently reported. Sjögren's syndrome
      may be associated with other autoimmune disorders (for example, rheumatoid arthritis
      or SLE); usually the clinical features of the associated disorder predominate.
   
   
   b. Documentation of Sjögren's syndrome. If you have Sjögren's syndrome, the medical evidence will generally, but not always,
      show that your disease satisfies the criteria in the current "Criteria for the Classification
      of Sjögren's Syndrome" by the American College of Rheumatology found in the most recent
      edition of the "Primer on the Rheumatic Diseases" published by the Arthritis Foundation.
   
   
   E. How do we document and evaluate immune deficiency disorders, excluding HIV
         infection?
   
   1. General. 
   
   a. Immune deficiency disorders can be classified as:
   
   (i) Primary (congenital); for example, X-linked agammaglobulinemia, thymic hypoplasia (DiGeorge
      syndrome), severe combined immunodeficiency (SCID), chronic granulomatous disease
      (CGD), C1 esterase inhibitor deficiency.
   
   
   (ii) Acquired; for example, medication-related.
   
   
   b. Primary immune deficiency disorders are seen mainly in children. However, recent
      advances in the treatment of these disorders have allowed many affected children to
      survive well into adulthood. Occasionally, these disorders are first diagnosed in
      adolescence or adulthood.
   
   
   2. Documentation of immune deficiency disorders. The medical evidence must include documentation of the specific type of immune deficiency.
      Documentation may be by laboratory evidence or by other generally acceptable methods
      consistent with the prevailing state of medical knowledge and clinical practice.
   
   
   3. Immune deficiency disorders treated by stem cell transplantation.
   
   a. Evaluation in the first 12 months. If you undergo stem cell transplantation for your immune deficiency disorder, we
      will consider you disabled until at least 12 months from the date of the transplant.
   
   
   b. Evaluation after the 12-month period has elapsed. After the 12-month period has elapsed, we will consider any residuals of your immune
      deficiency disorder as well as any residual impairment(s) resulting from the treatment,
      such as complications arising from:
   
   
   (i) Graft-versus-host (GVH) disease.
   
   (ii) Immunosuppressant therapy, such as frequent infections.
   
   (iii) Significant deterioration of other organ systems.
   
   4. Medication-induced immune suppression. Medication effects can result in varying degrees of immune suppression, but most
      resolve when the medication is ceased. However, if you are prescribed medication for
      long-term immune suppression, such as after an organ transplant, we will evaluate:
   
   
   a. The frequency and severity of infections.
   
   b. Residuals from the organ transplant itself, after the 12-month period has elapsed.
   
   c. Significant deterioration of other organ systems.
   
   F. How do we document and evaluate HIV infection?
   
   Any child with HIV infection, including one with a diagnosis of acquired immune deficiency
      syndrome (AIDS), may be found disabled under 114.11 if his or her impairment meets
      the criteria in that listing or is medically equivalent to the criteria in that listing.
   
   
   1. Documentation of HIV infection.
   
   a. Definitive documentation of HIV infection. We may document a diagnosis of HIV infection by positive findings on one or more
      of the following definitive laboratory tests:
   
   
   (i) HIV antibody screening test (for example, enzyme immunoassay, or EIA), confirmed
      by a supplemental HIV antibody test such as the Western blot (immunoblot) or immunofluorescence
      assay, for any child age 18 months or older.
   
   
   (ii) HIV nucleic acid (DNA or RNA) detection test (for example, polymerase chain reaction,
      or PCR).
   
   
   (iii) HIV p24 antigen (p24Ag) test, for any child age 1 month or older.
   
   (iv) Isolation of HIV in viral culture.
   
   (v) Other tests that are highly specific for detection of HIV and that are consistent
      with the prevailing state of medical knowledge.
   
   
   b. We will make every reasonable effort to obtain the results of your laboratory testing.
      Pursuant to § 416.919f, we will purchase examinations or tests necessary to make a
      determination in your claim if no other acceptable documentation exists.
   
   
   c. Other acceptable documentation of HIV infection. We may also document HIV infection without definitive laboratory evidence.
   
   
   (i) We will accept a persuasive report from a physician that a positive diagnosis
      of your HIV infection was confirmed by an appropriate laboratory test(s), such as
      those described in 114.00F1a. To be persuasive, this report must state that you had
      the appropriate definitive laboratory test(s) for diagnosing your HIV infection and
      provide the results. The report must also be consistent with the remaining evidence
      of record.
   
   
   (ii) We may also document HIV infection by the medical history, clinical and laboratory
      findings, and diagnosis(es) indicated in the medical evidence, provided that such
      documentation is consistent with the prevailing state of medical knowledge and clinical
      practice and is consistent with the other evidence in your case record. For example,
      we will accept a diagnosis of HIV infection without definitive laboratory evidence
      of the HIV infection if you have an opportunistic disease that is predictive of a
      defect in cell-mediated immunity (for example, toxoplasmosis of the brain or Pneumocystis pneumonia (PCP)), and there is no other known cause of diminished resistance to that
      disease (for example, long-term steroid treatment or lymphoma). In such cases, we
      will make every reasonable effort to obtain full details of the history, medical findings,
      and results of testing.
   
   
   2. Documentation of the manifestations of HIV infection.
   
   a. Definitive documentation of manifestations of HIV infection. We may document manifestations of HIV infection by positive findings on definitive
      laboratory tests, such as culture, microscopic examination of biopsied tissue or other
      material (for example, bronchial washings), serologic tests, or on other generally
      acceptable definitive tests consistent with the prevailing state of medical knowledge
      and clinical practice.
   
   
   b. We will make every reasonable effort to obtain the results of your laboratory testing.
      Pursuant to § 416.919f, we will purchase examinations or tests necessary to make a
      determination of your claim if no other acceptable documentation exists.
   
   
   c. Other acceptable documentation of manifestations of HIV infection. We may also document manifestations of HIV infection without definitive laboratory
      evidence.
   
   
   (i) We will accept a persuasive report from a physician that a positive diagnosis
      of your manifestation of HIV infection was confirmed by an appropriate laboratory
      test(s). To be persuasive, this report must state that you had the appropriate definitive
      laboratory test(s) for diagnosing your manifestation of HIV infection and provide
      the results. The report must also be consistent with the remaining evidence of record.
   
   
   (ii) We may also document manifestations of HIV infection without the definitive laboratory
      evidence described in 114.00F2a, provided that such documentation is consistent with
      the prevailing state of medical knowledge and clinical practice and is consistent
      with the other evidence in your case record. For example, many conditions are now
      commonly diagnosed based on some or all of the following: Medical history, clinical
      manifestations, laboratory findings (including appropriate medically acceptable imaging),
      and treatment responses. In such cases, we will make every reasonable effort to obtain
      full details of the history, medical findings, and results of testing.
   
   
   3. Disorders associated with HIV infection (114.11A-E).
   
   a. Multicentric Castleman disease. (MCD, 114.11A) affects multiple groups of lymph nodes and organs containing lymphoid
      tissue. This widespread involvement distinguishes MCD from localized (or unicentric)
      Castleman disease, which affects only a single set of lymph nodes. While not a cancer,
      MCD is known as a lymphoproliferative disorder. Its clinical presentation and progression
      is similar to that of lymphoma, and its treatment may include radiation or chemotherapy.
      We require characteristic findings on microscopic examination of the biopsied lymph
      nodes or other generally acceptable methods consistent with the prevailing state of
      medical knowledge and clinical practice to establish the diagnosis. Localized (or
      unicentric) Castleman disease does not meet or medically equal the criterion in 114.11A,
      but we may evaluate it under the criteria in 114.11G or 14.11I in part A.
   
   
   b. Primary central nervous system lymphoma. (PCNSL, 114.11B) originates in the brain, spinal cord, meninges, or eye. Imaging
      tests (for example, MRI) of the brain, while not diagnostic, may show a single lesion
      or multiple lesions in the white matter of the brain. We require characteristic findings
      on microscopic examination of the cerebral spinal fluid or of the biopsied brain tissue,
      or other generally acceptable methods consistent with the prevailing state of medical
      knowledge and clinical practice to establish the diagnosis.
   
   
   c. Primary effusion lymphoma (PEL, 114.11C) is also known as body cavity lymphoma. We require characteristic findings
      on microscopic examination of the effusion fluid or of the biopsied tissue from the
      affected internal organ, or other generally acceptable methods consistent with the
      prevailing state of medical knowledge and clinical practice to establish the diagnosis.
   
   
   d. Progressive multifocal leukoencephalopathy (PML, 114.11D) is a progressive neurological degenerative syndrome caused by the
      John Cunningham (JC) virus in immunosuppressed children. Clinical findings of PML
      include clumsiness, progressive weakness, and visual and speech changes. Personality
      and cognitive changes may also occur. We require appropriate clinical findings, characteristic
      white matter lesions on MRI, and a positive PCR test for the JC virus in the cerebrospinal
      fluid to establish the diagnosis. We also accept a positive brain biopsy for JC virus
      or other generally acceptable methods consistent with the prevailing state of medical
      knowledge and clinical practice to establish the diagnosis.
   
   
   e. Pulmonary Kaposi sarcoma (Kaposi sarcoma in the lung, 114.11E) is the most serious form of Kaposi sarcoma
      (KS). Other internal KS tumors (for example, tumors of the gastrointestinal tract)
      have a more variable prognosis. We require characteristic findings on microscopic
      examination of the induced sputum, bronchoalveolar lavage washings, or of the biopsied
      transbronchial tissue, or other generally acceptable methods consistent with the prevailing
      state of medical knowledge and clinical practice to establish the diagnosis.
   
   
   4. CD4 measurement (114.11F). To evaluate your HIV infection under 114.11F, we require one measurement of your
      absolute CD4 count (also known as CD4 count or CD4+ T-helper lymphocyte count) or
      CD4 percentage for children from birth to attainment of age 5, or one measurement
      of your absolute CD4 count for children from age 5 to attainment of age 18. These
      measurements (absolute CD4 count or CD4 percentage) must occur within the period we
      are considering in connection with your application or continuing disability review.
      If you have more than one CD4 measurement within this period, we will use your lowest
      absolute CD4 count or your lowest CD4 percentage.
   
   
   5. Complications of HIV infection requiring hospitalization (114.11G).
   
   
   a. Complications of HIV infection may include infections (common or opportunistic),
      cancers, and other conditions. Examples of complications that may result in hospitalization
      include: Depression; diarrhea; immune reconstitution inflammatory syndrome; malnutrition;
      and PCP and other severe infections.
   
   
   b. Under 114.11G, we require three hospitalizations within a 12-month period that
      are at least 30 days apart and that result from a complication(s) of HIV infection.
      The hospitalizations may be for the same complication or different complications of
      HIV infection and are not limited to the examples of complications that may result
      in hospitalization listed in 114.00F5a. All three hospitalizations must occur within
      the period we are considering in connection with your application or continuing disability
      review. Each hospitalization must last at least 48 hours, including hours in a hospital
      emergency department immediately before the hospitalization.
   
   
   c. We will use the rules on medical equivalence in § 416.926 to evaluate your HIV
      infection if you have fewer, but longer, hospitalizations, or more frequent, but shorter,
      hospitalizations, or if you receive nursing, rehabilitation, or other care in alternative
      settings.
   
   
   6. Neurological manifestations specific to children (114.11H). The methods of identifying
      and evaluating neurological manifestations may vary depending on a child's age. For
      example, in an infant, impaired brain growth can be documented by a decrease in the
      growth rate of the head. In an older child, impaired brain growth may be documented
      by brain atrophy on a CT scan or MRI. Neurological manifestations may present in the
      loss of acquired developmental milestones (developmental regression) in infants and
      young children or, in the loss of acquired intellectual abilities in school-age children
      and adolescents. A child may demonstrate loss of intellectual abilities by a decrease
      in IQ scores, by forgetting information previously learned, by inability to learn
      new information, or by a sudden onset of a new learning disability. When infants and
      young children present with serious developmental delays (without regression), we
      evaluate the child's impairment(s) under 112.00.
   
   
   7. Growth failure due to HIV immune suppression (114.11I).
   
   a. To evaluate growth failure due to HIV immune suppression, we require documentation
      of the laboratory values described in 114.11I1 and the growth measurements in 114.11I2
      or 114.11I3 within the same consecutive 12-month period. The dates of laboratory findings
      may be different from the dates of growth measurements.
   
   
   b. Under 114.11I2 and 114.11I3, we use the appropriate table under 105.08B in the
      digestive system to determine whether a child's growth is less than the third percentile.
   
   
   (i) For children from birth to attainment of age 2, we use the weight-for-length table
      corresponding to the child's gender (Table I or Table II).
   
   
   (ii) For children from age 2 to attainment of age 18, we use the body mass index (BMI)-for-age
      corresponding to the child's gender (Table III or Table IV).
   
   
   (iii) BMI is the ratio of a child's weight to the square of his or her height. We
      calculate BMI using the formulas in 105.00G2c.
   
   
   G. How do we consider the effects of treatment in evaluating your autoimmune
         disorder, immune deficiency disorder, or HIV infection?
   
   1. General. If your impairment does not otherwise meet the requirements of a listing, we will
      consider your medical treatment in terms of its effectiveness in improving the signs,
      symptoms, and laboratory abnormalities of your specific immune system disorder or
      its manifestations, and in terms of any side effects that limit your functioning.
      We will make every reasonable effort to obtain a specific description of the treatment
      you receive (including surgery) for your immune system disorder. We consider:
   
   
   a. The effects of medications you take.
   
   b. Adverse side effects (acute and chronic).
   
   c. The intrusiveness and complexity of your treatment (for example, the dosing schedule,
      need for injections).
   
   
   d. The effect of treatment on your mental functioning (for example, cognitive changes,
      mood disturbance).
   
   
   e. Variability of your response to treatment (see 114.00G2).
   
   f. The interactive and cumulative effects of your treatments. For example, many children
      with immune system disorders receive treatment both for their immune system disorders
      and for the manifestations of the disorders or co-occurring impairments, such as treatment
      for HIV infection and hepatitis C. The interactive and cumulative effects of these
      treatments may be greater than the effects of each treatment considered separately.
   
   
   g. The duration of your treatment.
   
   h. Any other aspects of treatment that may interfere with your ability to function.
   
   2. Variability of your response to treatment. Your response to treatment and the adverse or beneficial consequences of your treatment
      may vary widely. The effects of your treatment may be temporary or long term. For
      example, some children may show an initial positive response to a drug or combination
      of drugs followed by a decrease in effectiveness. When we evaluate your response to
      treatment and how your treatment may affect you, we consider such factors as disease
      activity before treatment, requirements for changes in therapeutic regimens, the time
      required for therapeutic effectiveness of a particular drug or drugs, the limited
      number of drug combinations that may be available for your impairment(s), and the
      time-limited efficacy of some drugs. For example, a child with HIV infection or another
      immune deficiency disorder who develops otitis media may not respond to the same antibiotic
      regimen used in treating children without HIV infection or another immune deficiency
      disorder, or may not respond to an antibiotic that he or she responded to before.
      Therefore, we must consider the effects of your treatment on an individual basis,
      including the effects of your treatment on your ability to function.
   
   
   3. How we evaluate the effects of treatment for autoimmune disorders on your ability
         to function. Some medications may have acute or long-term side effects. When we consider the effects
      of corticosteroids or other treatments for autoimmune disorders on your ability to
      function, we consider the factors in 114.00G1 and 114.00G2. Long-term corticosteroid
      treatment can cause ischemic necrosis of bone, posterior subcapsular cataract, impaired
      growth, weight gain, glucose intolerance, increased susceptibility to infection, and
      osteopenia that may result in a loss of function. In addition, medications used in
      the treatment of autoimmune disorders may also have effects on mental functioning,
      including cognition (for example, memory), concentration, and mood.
   
   
   4. How we evaluate the effects of treatment for immune deficiency disorders,
         excluding HIV infection, on your ability to function. When we consider the effects of your treatment for your immune deficiency disorder
      on your ability to function, we consider the factors in 114.00G1 and 114.00G2. A frequent
      need for treatment such as intravenous immunoglobulin and gamma interferon therapy
      can be intrusive and interfere with your ability to function. We will also consider
      whether you have chronic side effects from these or other medications, including severe
      fatigue, fever, headaches, high blood pressure, joint swelling, muscle aches, nausea,
      shortness of breath, or limitations in mental function including cognition (for example,
      memory) concentration, and mood.
   
   
   5. How we evaluate the effects of treatment for HIV infection on your ability to
         function.
   
   a. General. When we consider the effects of antiretroviral drugs (including the effects of highly
      active antiretroviral therapy (HAART)) and the effects of treatments for the manifestations
      of HIV infection on your ability to function, we consider the factors in 114.00G1
      and 114.00G2. Side effects of antiretroviral drugs include, but are not limited to:
      Bone marrow suppression, pancreatitis, gastrointestinal intolerance (nausea, vomiting,
      diarrhea), neuropathy, rash, hepatotoxicity, lipodystrophy (fat redistribution, such
      as "buffalo hump"), glucose intolerance, and lactic acidosis. In addition, medications
      used in the treatment of HIV infection may also have effects on mental functioning,
      including cognition (for example, memory), concentration, and mood, and may result
      in malaise, severe fatigue, joint and muscle pain, and insomnia. The symptoms of HIV
      infection and the side effects of medication may be indistinguishable from each other.
      We will consider all of your functional limitations, whether they result from your
      symptoms or signs of HIV infection or the side effects of your treatment.
   
   
   b. Structured treatment interruptions. A structured treatment interruption (STI, also called a "drug holiday") is a treatment
      practice during which your treating source advises you to stop taking your medications
      temporarily. An STI in itself does not imply that your medical condition has improved;
      nor does it imply that you are noncompliant with your treatment because you are following
      your treating source's advice. Therefore, if you have stopped taking medication because
      your treating source prescribed or recommended an STI, we will not find that you are
      failing to follow treatment or draw inferences about the severity of your impairment
      on this fact alone. We will consider why your treating source has prescribed or recommended
      an STI and all the other information in your case record when we determine the severity
      of your impairment.
   
   
   6. When there is no record of ongoing treatment. If you have not received ongoing treatment or have not had an ongoing relationship
      with the medical community despite the existence of a severe impairment(s), we will
      evaluate the medical severity and duration of your immune system disorder on the basis
      of the current objective medical evidence and other evidence in your case record,
      taking into consideration your medical history, symptoms, clinical and laboratory
      findings, and medical source opinions. If you have just begun treatment and we cannot
      determine whether you are disabled based on the evidence we have, we may need to wait
      to determine the effect of the treatment on your ability to develop and function in
      an age-appropriate manner. The amount of time we need to wait will depend on the facts
      of your case. If you have not received treatment, you may not be able to show an impairment
      that meets the criteria of one of the immune system disorders listings, but your immune
      system disorder may medically equal a listing or functionally equal the listings.
   
   
   H. How do we consider your symptoms, including your pain, severe fatigue, and
         malaise?
   
   Your symptoms, including pain, severe fatigue, and malaise, may be important factors
      in our determination whether your immune system disorder(s) meets or medically equals
      a listing or in our determination whether you otherwise have marked and severe functional
      limitations. In order for us to consider your symptoms, you must have medical signs
      or laboratory findings showing the existence of a medically determinable impairment(s)
      that could reasonably be expected to produce the symptoms. If you have such an impairment(s),
      we will evaluate the intensity, persistence, and functional effects of your symptoms
      using the rules throughout 114.00 and in our other regulations. See §§ 416.921 and
      416.929. Additionally, when we assess the credibility of your complaints about your
      symptoms and their functional effects, we will not draw any inferences from the fact
      that you do not receive treatment or that you are not following treatment without
      considering all of the relevant evidence in your case record, including any explanations
      you provide that may explain why you are not receiving or following treatment.
   
   
   NOTE: SSR 96-7p, "Titles II and XVI: Evaluation of Symptoms in Disability Claims: Assessing
      the Credibility of an Individual's Statements" has been replaced with SSR 16-3p, "Titles II and XVI: Evaluation of Symptoms in Disability Claims." Effective 3/28/16,
      we no longer use the term "credibility" when evaluating symptoms.
   
   
   I. How do we consider the impact of your immune system disorder on your
         functioning?
   
   1. We will consider all relevant information in your case record to determine the
      full impact of your immune system disorder, including HIV infection, on your ability
      to function. Functional limitation may result from the impact of the disease process
      itself on your mental functioning, physical functioning, or both your mental and physical
      functioning. This could result from persistent or intermittent symptoms, such as depression,
      diarrhea, severe fatigue, or pain, resulting in a limitation of your ability to acquire
      information, to concentrate, to persevere at a task, to interact with others, to move
      about, or to cope with stress. You may also have limitations because of your treatment
      and its side effects (see 114.00G).
   
   
   2. Important factors we will consider when we evaluate your functioning include, but
      are not limited to: Your symptoms (see 114.00H), the frequency and duration of manifestations
      of your immune system disorder, periods of exacerbation and remission, and the functional
      impact of your treatment, including the side effects of your medication (see 114.00G).
      See §§416.924a and 416.926a for additional guidance on the factors we consider when
      we evaluate your functioning.
   
   
   3. We will use the rules in §§ 416.924a and 416.926a to evaluate your functional limitations
      and determine whether your impairment functionally equals the listings
   
   
   J. How do we evaluate your immune system disorder when it does not meet one of the
         listings?
   
   1. These listings are only examples of immune system disorders that we consider severe
      enough to result in marked and severe functional limitations. If your impairment(s)
      does not meet the criteria of any of these listings, we must also consider whether
      you have an impairment(s) that satisfies the criteria of a listing in another body
      system.
   
   
   2. Children with immune system disorders, including HIV infection, may manifest signs
      or symptoms of a mental impairment or of another physical impairment. For example,
      HIV infection may accelerate the onset of conditions such as diabetes or affect the
      course of or treatment options for diseases such as cardiovascular disease or hepatitis.
      We may evaluate these impairments under the affected body system.
   
   
   a. Growth impairment under 100.00.
   
   b. Musculoskeletal involvement, such as surgical reconstruction of a joint, under
      101.00.
   
   
   c. Ocular involvement, such as dry eye, under 102.00.
   
   d. Respiratory impairments, such as pleuritis, under 103.00.
   
   e. Cardiovascular impairments, such as cardiomyopathy, under 104.00.
   
   f. Digestive impairments, such as hepatitis (including hepatitis C) or weight loss
      as a result of HIV infection that affects the digestive system, under 105.00.
   
   
   g. Genitourinary impairments, such as nephropathy, under 106.00.
   
   h. Hematologic abnormalities, such as anemia, granulocytopenia, and thrombocytopenia,
      under 107.00.
   
   
   i. Skin impairments, such as persistent fungal and other infectious skin eruptions,
      and photosensitivity, under 108.00.
   
   
   j. Neurologic impairments, such as neuropathy or seizures, under 111.00.
   
   k. Mental disorders, such as depression, anxiety, or cognitive deficits, under 112.00.
   
   l. Allergic disorders, such as asthma or atopic dermatitis, under 103.00 or 108.00
      or under the criteria in another affected body system.
   
   
   m. Syphilis or neurosyphilis under the criteria for the affected body system, for
      example, 102.00 Special senses and speech, 104.00 Cardiovascular system, or 111.00
      Neurological.
   
   
   3. If you have a severe medically determinable impairment(s) that does not meet a
      listing, we will determine whether your impairment(s) medically equals a listing.
      (See §416.926.) If it does not, we will also consider whether you have an impairment(s)
      that functionally equals the listings. (See §416.926a.) We use the rules in §416.994a
      when we decide whether you continue to be disabled.
