[Multiple digestive involvement in visceral leishmaniasis in a patient with HIV infection: favourable course with itraconazole].

We report a case of visceral leishmaniasis due to Leishmania infantum in a 35 year-old patient with acquired immunodeficiency syndrome who complained of chronic diarrhea. Biopsy specimens of gastric and duodenal mucosa and bone marrow aspirate led to the diagnosis. Enterocytozoon bieneusi, fortuitously found in the duodenal mucosa, did not seem to be the causative agent of diarrhea in this case, but its association with visceral leishmaniasis is rare. A treatment with itraconazole brought about a sustained clinical remission.

[Appearance of hepatitis C virus replication and increase of aminotransferase activity after corticoid treatment of presumed autoimmune hepatitis. 2 cases].

Autoimmune-related and hepatitis C virus-related chronic hepatitis are sometimes difficult to differentiate. We report two cases of chronic hepatitis with high levels of serum anti-smooth muscle antibodies, positive hepatitis C virus serology, and negative serum RNA, which were first treated with corticotherapy. Both patients responded with marked increases in aminotransferase levels, and positive RNA. The first case may have been type 1 autoimmune hepatitis with hepatitis C virus infection, and the second chronic hepatitis C with positive serum auto-antibodies. The increase in viral antigen expression on the surface of the hepatocytes following corticosteroid treatment may have favoured a direct cytopathogenic effect of hepatitis C virus.

[Necrotizing amebic colitis].

We report a case of necrotizing amebic colitis in a 43 year-old patient, 10 years after a stay in Senegal, successfully treated by right hemicolectomy. Entamoeba histolytica were found in colon necrosis and amoebiasis serology was positive, leading to the diagnosis. The epidemiologic, physiopathologic, clinical and therapeutic features of this exceptional affection are described. A few cases have been previously reported in non endemic areas where pre-operative diagnosis is rarely made. In endemic areas, a conservative treatment by ileostomy and colonic lavage seems to reduce the death rate.
