Progressive histopathologic abnormalities in the persistent generalized lymphadenopathy syndrome

Abstract

Using a quantitative classification, we evaluated serial lymph node biopsies in 20 homosexual men with Persistent Generalized Lymphadenopathy (PGL), and correlated the results with peripheral blood lymphocyte counts and clinical findings. In a median follow-up interval of 19 months, ten patients (50%) had progression from one histologic subtype of this disorder to another. Lymph nodes from the other 10 patients also demonstrated decreased numbers of organized follicles in the most recent specimens, in addition to progressive abnormalities of other histologic parameters and peripheral blood T4 counts. This suggests that these patients do not have stable disease. However, in a median follow-up interval of 19 months, only one (5%) of the patients had developed AIDS. We conclude that progressive lymph node histopathologic subtypes do not correlate well with decreased T4 lymphocyte counts or clinical course over a short time interval.
