virulence gene-induced pulmonary and systemic tuberculosis in a young woman with normal immune function: A case report.

Background: Tuberculosis is a chronic infectious disease and an important public health problem. Despite progress in controlling tuberculosis, the incidence of tuberculosis in China is still very high, with 895000 new cases annually. This case report describes the investigation of a case of severe disseminated tuberculosis in a young adult with normal immune function, conducted to ascertain why a () strain caused such severe disease.

[Association of P450-2E1 and GSTM1 genetic polymorphisms with susceptibility to antituberculosis drug-induced hepatotoxicity].

Objective: To observe the relationship between the genetic polymorphism of P450-2E1 and the risk for antituberculosis drug-induced hepatotoxicity in a Chinese population.

Methods: Blood samples and clinical data were collected from 85 patients with antituberculosis drug-induced hepatotoxicity and 100 tuberculosis patients without hepatotoxicity as the control. DNA was extracted from the blood samples, and the frequencies of P450-2E1 RsaI genotypes were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
