We report a fatal case of coxsackievirus B4 chronic infection in a 30-year-old woman with a diagnosis of myelin oligodendrocyte glycoprotein antibody-associated disorder controlled by rituximab monotherapy for 3 years. Initially presenting as self-limited meningitis, the infection remained silent for 8 months before the sudden onset of fulminant myocarditis. Analysis of the complete genome showed that the same virus was responsible for both episodes.
Hepatitis C virus (HCV) infection is a worldwide concern. Knowledge of the HCV genotype is clinically important because it predicts the rate of response to therapy and guides the treatment duration. Moreover, it allows molecular epidemiology to be performed. To our knowledge, the prevalence of HCV genotypes has been assessed only once in Albania, using a line probe genotyping assay. We determined HCV genotypes by population sequencing of HCV-infected patients in Tirana, Albania. HCV genotype and sequence analyses were performed for serum samples collected from January 2011 through May 2012 from 61 HCV-seropositive patients using population sequencing of the NS3 protease gene and alternatively the NS5b gene and the 5' untranslated region (UTR). HCV RNA was retrieved from the blood samples of 50 patients. The HCV NS3 protease gene was sequenced for 28 patients and NS5b and/or 5'UTR fragments were sequenced for an additional 22 patients. The predominant genotype was 1b in 25 patients (50%), followed by genotypes 2c, 4a, 3a, and 1a in 18%, 14%, 8%, and 6% of cases, respectively. Best matches for these HCV RNAs in GenBank were obtained in different countries worldwide. One NS3 protease naturally harbored an amino acid conferring minor drug resistance to newly available HCV protease inhibitors. In conclusion, HCV-1b was predominant in the present Albanian population, as in southeastern Europe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
