Cytomegalovirus infection of the central nervous system in patients with AIDS: diagnosis by DNA amplification from cerebrospinal fluid.

A nested polymerase chain reaction (PCR) was evaluated for the detection of cytomegalovirus (CMV) DNA in cerebrospinal fluid (CSF). CSF and serum samples from 19 AIDS patients with intracerebral CMV infection diagnosed at autopsy were retrospectively examined. As controls, CSF and serum samples from 15 AIDS patients with only extracerebral CMV involvement at autopsy, from 10 AIDS patients without CMV infection at autopsy, and from 10 anti-human immunodeficiency virus-negative patients without ongoing CMV infection, were studied. CMV DNA was detected from patients with intracerebral CMV infection in 9 of 9, 5 of 6, and 1 of 4 CSF samples collected, respectively, 1-30, 30-90, and 90-300 days before death. Twelve of 13 sera from these patients were CMV PCR-positive. None of the control patients had CMV DNA in CSF. PCR was positive in 6 of 8 sera from AIDS patients with only extracerebral CMV infection and in serum from 1 AIDS patient without CMV involvement at autopsy. CMV PCR on CSF is highly sensitive and specific. It should be considered a rapid and reliable diagnostic method for CMV infection of the central nervous system.

Experiences with immunomodulant agents in HIV infections.

Drug addicts with persistent generalized lymphadenopathy displayed the following immunological abnormalities: an inverted OKT4/OKT8 ratio, a depressed in vitro blastogenetic response to phytohemagglutinin and pokeweed mitogen (PWM), a reduced ability of PMNL to phagocytose and kill Candida albicans spores and to migrate in presence of a chemotactic factor. Thymopentin treatment (50 mg s.c. 3 times/week for 3 weeks and repeated after 3 months at 50 mg s.c. once a week for 3 months) improved OKT4+ lymphocytes (p less than 0.05) and the blastogenesis to PWM (p less than 0.01); moreover, at the end of the first cycle, the chemotaxis of neutrophils was increased to normal values.

Role of PMN's candidicidal activity in the pathogenesis of AIDS-related systemic candidiases.

Phagocytic and fungicidal activity towards C. albicans spores were tested in 9 patients with AIDS-Related Complex (ARC), but without Candida infections, and in 13 patients with AIDS and deep candidiasis. No significant differences were observed between the two mentioned groups as far as PMN's phagocytosis and killing were concerned. PMN's migration in response to a "non-mycotic" chemoattractant was defective in both groups; although, from this point of view, patients with candidiasis were more severely affected. A significant difference was noted, instead, as far as mean T helper values were concerned; in fact, their number was significantly lower in patients with systemic candidiasis than in those with ARC or even AIDS, but oesophageal candidiasis only. In conclusion, defective PMN's activity towards C. albicans spores, as observed in vitro, does not seem in itself to predispose AIDS patients to candidiasis in vivo; mycoses may be rather due to defects of cell-mediated immunity as a whole.

Diagnostic and prognostic significance of beta 2-microglobulin during HIV infection.

The serum levels of beta 2-microglobulin (beta 2-m) were determined in 80 intravenous drug addicts (IVDA) with acquired immunodeficiency syndrome (AIDS), in 128 HIV-positive IVDA with persistent generalized lymphadenopathy (PGL) and in 44 HIV-seronegative IVDA. Seventy-two out of 80 (90%) AIDS patients had elevated serum beta 2-m levels and high levels of beta 2-m were also found in 105 of 128 (82%) HIV-infected subjects without AIDS. The mean beta 2-m level was significantly higher in HIV-infected patients with PGL than in HIV-negative IVDA. Nine out of 64 (14%) PGL patients developed AIDS in a period of 24-54 months. In these patients the mean beta 2-m level (5.16 +/- 2.37 mg/l), obtained from sera stored at the first observation, was significantly higher than in the other PGL patients (3.40 +/- 1.03 mg/l); in particular, 5 out of 7 PGL patients with beta 2-m levels greater than 5.0 mg/l showed an advanced disease.
