Behaviour of different clinical, immunological and serological parameters observed in a group of HIV positive patients during a 12 month treatment period with zidovudine.

During a 12 month open clinical trial, 14 patients (6 with AIDS, 2 with ARC and 6 with PGL) were continuously administered a daily 1200 mg dose of Zidovudine. Clinical course was correlated with a number of serological (HIV p24 antigen, p17 and p24 antibodies) and immunological (CD4 cell counts, serum neopterin and beta 2-microglobulin levels) parameters. All patients survived until the end of the trial: none developed major opportunistic infections, but 5 required an average of 7 blood transfusions each.

CD4+:neopterin ratio correlates with p24 antigenaemia in HIV infected patients.

In an effort to improve the Walter Reed Staging System (WR), which mainly relies on immune depletion parameters, by introducing viral replication and T-cell activation markers, we examined by p24 antigenaemia and serum neopterin levels (SNL) 72 HIV positive PGL, ARC and AIDS patients (11 of whom classified as WR 2, 21 as WR 3, 16 as WR 5 and 24 as WR 6). While CD4 cell counts, already weakly correlating with the WR itself, did not significantly differ between p24 antigen (p24 AG) positive and negative patients, striking differences between the two groups, especially in PGL patients (p less than 0.0001), were found as far as SNL was concerned.

HIV-related severe thrombocytopenia in intravenous drug users: prevalence, response to therapy in a medium-term follow-up, and pathogenetic evaluation.

Severe thrombocytopenia (TP) accounted for 5.3% of cases in a consecutive series of 380 HIV-infected intravenous drug users (IVDUs) at presentation. Forty-one of 53 subjects with severe TP showed haemorrhages and were treated as follows: ten were splenectomized, 17 were given high-dose intravenous immunoglobulins (HDIg), and 10 received anti-Rh(D) immunoglobulins (anti-Rh Ig).

Single-dose fosfomycin trometamol versus multiple-dose cotrimoxazole in the treatment of lower urinary tract infections in general practice. Multicenter Group of General Practitioners.

A randomized trial, comparing a single dose treatment of fosfomycin trometamol (FT, 3 g) versus a 3-times daily regimen of cotrimoxazole (CTX, 960 mg) was carried out in women with uncomplicated urinary tract infections. Of 36 evaluable patients, 19 were treated with FT and 17 with TMP. The bacteriological results after 4 weeks of follow-up were in the FT group (n = 19): cure in 17 (89%), and failure in 2 (11%).
