title: Lymph node biopsy in the diagnostic and prognostic assessment of patients with HIV infection.
abstract: Thirty-three anti-HIV positive patients with persistent generalized lymphadenopathy (PGL) who underwent lymph-node biopsy were studied to assess the diagnostic and prognostic relations existing between clinical, histological and laboratory findings. Patients were also examined for known risk factors, laboratory and bacteriological tests, and mononuclear cell surface marker analysis. 4 histological types were identified according to Ràcz's classification. At biopsy, there were 21 cases of LAS (64%), 6 cases of ARC (18%) and 6 cases of AIDS (18%); a clear prevalence of type 1 was evidenced in LAS/ARC patients, while only type 4 was present in the AIDS group. An ARC type 3 patient developed manifest AIDS within 13 months from biopsy. These results suggest that anti-HIV positive asymptomatic patients with PGL apparently do not require lymph node biopsy, as none of them showed histologic findings suggestive of opportunistic infections, malignant lymphoma or Kaposi's sarcoma. On the contrary, lymph node biopsy can play a diagnostic and prognostic role in anti-HIV negative subjects with PGL, and in ARC and AIDS patients.
