Impact of protease inhibitors on AIDS-defining events and hospitalizations in 10 French AIDS reference centres. Fédération National des Centres de Lutte contre le SIDA.

OBJECTIVE: To assess the clinical and economic consequences of the use of protease inhibitors in the treatment of HIV infection. DESIGN: Multicentric, observational, retrospective cohort study. SETTING: Ten AIDS reference centres in France. PATIENTS: All patients followed in each centre from September 1995 through October 1996. MAIN OUTCOME MEASURES: AIDS-defining events, death, health-care resources use, administration of antiretroviral therapy. RESULTS: Data from 7749 patients in 10 centres showed a drop in hospitalization days by 35%, new AIDS cases by 35%, and deaths by 46%. In the same period, the proportion of patients receiving antiretrovirals rose from 36 to 53% including highly active antiretroviral therapy (HAART), which rose from 0.3 to 18%. Overall cost evaluation showed a slight increase of monthly treatment cost of US$ 12 per patient. Comparison of the three centres that used HAART earliest to the three centres that used it latest showed a clear benefit to early HAART with a drop in hospitalization days by 41%, new AIDS cases by 41% and deaths by 69%. The proportion of patients with HAART rose to 27% and monthly health-care cost decreased by US$ 248852 (i.e., by US$ 101 per patient per month). Late prescribing centres experienced a less marked effect with a drop in hospitalization days by 22%, new AIDS cases by 31%, and deaths by 32.5%. Proportion of patients with HAART rose to 12% and monthly health-care costs increased by US$ 113578 (i.e., by US$ 38 per patient per month). CONCLUSIONS: This study supports the extensive use of HAART in HIV-infected patients.

Sustained bacteremia in 26 patients with a permanent endocardial pacemaker: assessment of wire removal.

We reviewed the data on 26 patients with permanent endocardial pacemakers who had 28 episodes of bacteremia to determine whether removal of the wire is required. Patients recovered completely from the first episode in seven of 20 cases of staphylococcal bacteremia and in six of six cases of nonstaphylococcal bacteremia (P = .015). Definitive cure was not achieved during the first episode in seven cases of staphylococcal bacteremia related to the pacing system when the wire was not withdrawn; however, cure was achieved in five of six cases when the whole pacemaker was removed (P < .01). The duration of treatment was longer for the patients from whom the wire was not removed during the first episode (P < .01). Whether cases of staphylococcal bacteremia were related to the pacing system or not, the rate of recovery of the responsible microorganism from the wires was similar for both groups of patients (six [82%] of seven and three [75%] of four, respectively). Nonstaphylococcal bacteremia was unrelated to the pacing system in five of six cases; these patients were all cured without removal of the wire.
