Test results within normal range: electrolytes (including calcium), glucose, kidney and liver function tests, white blood cell count with differential and platelets, free T4, IgM, IgA, indirect Coombs' test, erythrocyte sedimentation rate, C-reactive protein, troponin T; global coagulation parameters; urine analysis, urinary free lambda light chains; anti-extractable nuclear antigens antibodies (SS-B/La, Scl-70 and Jo-1), anti-dsDNA; anti-mitochondrial (AMA), anti-neutrophil cytoplasmic (ANCA) against myeloperoxidase (MPO) and proteinase-3 (PR3), anti-liver kidney microsomal, anti-parietal cell, anti-transglutaminase IgA and IgG, and anti-cardiolipin IgG and IgM antibodies; rheumatoid factor; angiotensin converting enzyme; complement levels C3 and C4; candida culture, serology on single determination for hepatitis viruses A, B and C, human immunodeficiency virus antigen/antibody, cytomegalovirus, herpes simplex virus-1 and -2, and varicella-zoster virus. Elevated ACTH reduced within days to normal values upon administration of increased doses of cortisone acetate resulting in cortisol levels of around 400 ng/mL (normal range: 65 – 250).

Abbreviations: ANA, antinuclear antibodies; RNP/Sm, combined nuclear ribonucleoprotein Smith antigen.
