ABSTRACT
Summary A cross-sectional study led in Bamako analyzed the seroprevalence of hepatitis C virus (HCV) and its genotypes among 91 patients carrying chronic liver diseases at the stage of cirrhosis (53) or hepato cellular carcinoma (38) and, on comparative basis in 92 blood donors as control population. False serologic reactions were found with ELISA (3/91 either 3,3% of the liver diseases and 1/92 or 1,1% of the control). Positive tests by ELISA confirmed by a RIBA test were finally considered. Concerning all the liver diseases, the seroprevalence of HCV was 15,4% including 15,1% in cirrhosis, 21% in hepatocellular carcinoma patients versus 2,2% in blood donors. The HBs antigen was associated in 5,6% of the cases In the hepatite C population, genotype 2a/2c was definitely prevalent, about 85,7%. Thus the role of the HCV in genesis of cirrhosis and hepatocellular carcinoma in Mali, appears significant.
ABSTRACT
Summary Aims The coinfection of the VIH and the schistosomiasis is affections brought back in schistosomiasis endemic area. We valued the level of morbidity partner to the schistosomiasis in hospital yard to patients hospitalized without distinction of immunological statute of patients. Patients and Methods Our study was retrospective and prospective. We included all patients hospitalized to internal Medicine and infectious diseases carriers of schistosomiasis to the mucous rectal biopsy and parasitologic exam of stools and urines between January 1998 and July 2005. Results Twenty-four patients were included in the survey of which 15 of masculine sex (62,50%) and 9 of feminine sex (37,50%). The sex ratio (H/F) = 1,66. The most tainted professions were pupils, peasants and housewives. Ten patients had benefited from the VIH tracking (41,66%) and 6 patients were seropositive for the VIH (25%). Sixty fifteen percent of patients accommodated Schistosoma haematobium (18 cases), 20,83% Schistosoma mansoni (5 cases) and 1 patient had a mixed infection. It doesn't exist a statistically difference between the frequency of species met (p = 0,061) . The main motives of hospitalization were the fever (12,50%), the hepatomegaly and splenomegaly, the ascite, the abdominal pain associated to the diarrhea and the diarrhea associated to an anemic syndrome with 8,20% for each of these motives. The most frequent clinical symptomatology was diarrhea (12,50%). The underlying pathologies more associated were the opportunist infections of the VIH (8,30%) the cirrhosis (12,50%), a syndrome amoebic dysentery syndrome (8,30%), a hepatic granuloma (8,30%). In the group of patients HIV positive the symptomatology was made of chronic and /or of glair - bloody diarrhea. One alone patient with a rate of CD4 = 279/mm3 presented prurigos in bouquet on the right flank. All patients without immunological statute distinction answered favorably to the treatment by the praziquantel. Conclusion The schistosomiasis stays even frequent in hospital yard of Bamako. The best understanding of the interaction between HIV and schistosomiasis is a pledge of the success of struggle programs in endemic area of schistosomiasis and of VIH.
