No.	Age/Sex	Fever	Arthralgia/ arthritis	Rash	LAP	H/S	WBC (% of granulocyte)†	RF	ANA	W ESR (mm/hr)	Ferritin (ng/ml)	AST/ALT (IU/l)	LDH(IU/l)	F/U (Mo)	Type of LAP¶
ALT, alanine aminotransferase; ANA, antinuclear antibody; AST, aspartate aminotransferase; F/U, follow up; H/S, hepatomegaly/splenomegaly; LAP, multiple lymphadenopathy; LDH, lactate dehydrogenase; Mo, months; NA, not available; No., patient number; oligo, oilgoarticular (2 to 4 joints affected); poly, polyarticular (5 or more joints affected); RF, rheumatoid factor; WBC, white blood cell count; W ESR, Westergren erythrocyte sedimentation rate.
Westergren ESR: normal range, 0–20 mm/hr; ferritin: normal range, 10–300 ng/ml; AST/ALT: normal range, 0–40 IU/litre; LDH: normal range, 100–225 IU/litre.
*Positive at the dilution factor shown. †WBC in units of ×10⁹ cells/litre (normal range, 4–10×10⁹ cells/litre). ¶Type of LAP, type of lymphadenopathy; I, atypical paracortical hyperplasia pattern; II, burnt out histiocytic pattern; III, exuberant immunoblastic reaction pattern; IV, follicular hyperplasia pattern.
