Résumé
A study was carried out in Thailand to determine the frequency of reactivity to delayed-type hypersensitivity (DTH) skin tests used for the staging of HIV patients in the United States. A four-antigen panel which included tetanus toxoid (1:10), Candida (1:10), mumps and Trichophyton antigens was assessed in 221 adult subjects from across the full immunological spectrum of HIV disease. Complete anergy was found in 38 per cent of 73 subjects with CD4 counts of 0-200 cells/ml and in 6 per cent of 78 subjects with 201-400 cells/ml. Partial anergy (response to 1 of 4 antigens) was found in 26 per cent of the 0-200 cell/ml group and decreased progressively with increasing CD4 cell count. Results suggested that a 3-member recall antigen panel would provide nearly all the clinically useful information gained by the more standard 4-member panel. In conclusion, DTH skin testing was confirmed to provide a method of assessing the integrity of cellular immune function of HIV-infected Thai adults which correlated with disease progression.

Cefpirome is a fourth-generation cephalosporin with good activity against both gram-positive and gram-negative bacteria. A multicentre trial was performed to study the efficacy and safety of cefpirome 2 g twice daily in the treatment of sepsis. Sixty-three cases were recruited from 10 hospitals from April 1996 to January 1998. Fifty seven cases could be evaluated according to the protocol. The APACHE II score was used to measure severity of illness, with 46.9 per cent of patients having APACHE II score more than 10 and two patients more than 20; both were cured. The most common pathogens were gram-negative bacteria with E. coli predominating 16/40 (40.0%), followed by Klebsiella 8/40 (20.0%). The overall clinical success rates were 54 out of 57 patients (94.7%). In patients with positive blood culture, the clinical cures were achieved for 20/22 (90.9%). Cefpirome showed good efficacy and safety in the empirical treatment of suspected bacteremia or sepsis.
