OBJECTIVE: Intrafamilial transmission of hepatitis C virus in human immunodeficiency virus and hepatitis C virus co-infections is not well documented. This cross-sectional study evaluated the transmission of hepatitis C virus in the sexual partners of hepatitis C virus and human immunodeficiency virus co-infected patients. METHODS: Hemophiliacs and transfused hepatitis C virus and human immunodeficiency virus co-infected patients who were being seen in three French university hospitals, and their sexual partners were studied by a face-to-face interview using an epidemiological questionnaire and by biological tests: antibodies against hepatitis C virus, hepatitis C virus RNA, and ALT activity. RESULT: Fifty-two subjects were included: 26 cases and their 26 sexual partners. Three sexual partners (11.5 %) had anti-hepatitis C virus antibodies, two of whom had an undetermined RIBA test. All three had a risk factor for hepatitis C virus infection (transfusion, intra-muscular injections with re-usable needles). Two of these three partners were also human immunodeficiency virus antibody positive. Hepatitis C virus RNA was negative in all sexual partners. CONCLUSION: This study provides evidence of a low prevalence of anti-hepatitis C virus antibodies in sexual partners of hepatitis C virus and human immunodeficiency virus co-infected patients. It does not support intra-familial transmission of hepatitis C virus.

The metabolism of tianeptine, a novel antidepressant that presents original neurochemical properties, was studied after a single oral administration of radioisotopically (14C) labeled compound to six healthy male volunteers. After 7 days, approximately 66% of the dose was eliminated by renal excretion (55% during the first 24 hr). Tianeptine is extensively metabolized, and 24 hr after the administration, the unchanged molecule contributed in urine for less than 3% of the administered dose. Chromatographic and mass spectral studies showed that beta-oxidation of the amino acid side chain is the major route of biotransformation for tianeptine. Three major metabolites, accounting for 29% of the dose, were products of beta-oxidation. The metabolite profiles of tianeptine in feces and plasma were qualitatively similar to that in urine.

Aseptic osteonecrosis following renal transplantation occurs in about 20 p. 100 of cases and entails important functional consequences. 16 patients with kidney transplant and 4 patients on chronic dialysis because of previous graft rejection underwent 27 orthopaedic operations, 8 of which being hip arthroplasties. During and after the procedure the anesthesiologist had to manage with drug interaction, coagulation disorders, blood compatibility problems etc... Despite poor general condition of patients and the risk of infectious complications linked to the never interrupted immunosupressive treatment, the surgical results of our serial were good.
