 AB    We report the first results of a clinical trial conducted to test the
       response of CD4-CD8 lymphocyte system to the administration of
       N-Acetyl-L-Cysteine (NAC). HIV-positive patients bearing CD4 counts <
       500 cells/mm3 measured by flow cytometry were studied. Patients were
       divided in 2 groups that received doses every 12 Hs during 1 mo., 8
       cases Parenteral, 400 mg. 7 cases Oral, 600 mg. Five of the patients
       were being treated with AZT without significant change of CD4 counts.
       RESULTS: TABULAR DATA, SEE ABSTRACT VOLUME. Two of the 8 successful
       cases became serum p24 antigen negative. The 6 cases of the parenteral
       group ceased to develop opportunistic infections so far. No side effects
       were reported in both groups. CONCLUSION: NAC associated to antiviral
       therapy can be a powerful immunotherapy drug. Current research effort is
       aimed to determine the clinical meaning of CD4-CD8 enhancement and the
       determination of a suitable maintenance schedule.
