Ethnic differences in the presentation of chronic hepatitis C.

Hispanics comprise 13% of the population in the United States and are the fastest growing minority group. Features of hepatitis C in Hispanics have not been well characterized. The aims of this study were to compare features of hepatitis C among Hispanics, Whites, and African-Americans and to characterize hepatitis C infection in Hispanics. A retrospective analysis was performed on 1225 consecutive patients with hepatitis C seen at the University of Illinois at Chicago including 227 Hispanics, 508 Whites, and 490 African-Americans. Data collection consisted of demographic variables, risk factors for hepatitis C, history of alcohol use, laboratory parameters and liver histology. Pair-wise comparisons showed that Hispanics had higher aminotransferase levels than Whites and African-Americans. Hispanics had higher portal inflammation scores on liver biopsy than African-Americans (P = 0.002) and Whites (P = 0.043). Hispanics had a higher frequency of cirrhosis than African-Americans (P < 0.001) and a trend towards more cirrhosis than Whites (P = 0.165). There was a trend towards a higher prevalence of cirrhosis in Hispanic women (56%) than in Hispanic men (45%) [P = 0.14]. A cross-sectional analysis of patients at our liver center showed that Hispanics with hepatitis C had higher aminotransferase levels, more portal inflammation than Whites and African-Americans, and a higher prevalence of cirrhosis than African-Americans.

[Acquired resistance of M tuberculosis to the antitubercular drugs in Chile from 1988 to 1991].

Acquired drug resistance appears in patients that are or have been in treatment for tuberculosis (relapses, abandons and failures). The aim of this study was to maintain an epidemiologic surveillance on the incidence of acquired drug resistance among previously treated patients and treatment failures. In 896 strains (518 in 1988 and 378 in 1991) coming from these type of patients, the pattern of sensitivity towards agents used in the treatment of tuberculosis was studied. There was an increase in the frequency of acquired resistance from 24.5% in 1988 to 32.3% in 1991. This increment was observed in the group of treatment failures, where the resistance to the combination streptomycin-isoniazid-rifampin had special relevance. This situation is epidemiologically and clinically negative since it generates primary resistance and chronicity. The increment in acquired resistance forces a revision of tuberculosis treatment, specially in its operational features.
