Health-Related Quality of Life and Its Influencing Factors in Patients with Hepatitis B: A Cross-Sectional Assessment in Southeastern China.

Health-related quality of life (HRQoL) is an important aspect in the management of patients with hepatitis B (HB), which remains a serious health problem in China. There have been relatively few HRQoL studies involving Chinese patients with HB. The aim of this study was to analyze HRQoL in patients diagnosed with HB living in Zhejiang Province, China. A cross-sectional sample of 98 patients with chronic HB (CHB), 56 patients with advanced HB that have developed cirrhosis, and 48 healthy controls (HCs), all from Zhejiang Province, was used in this study. HRQoL was assessed using Short-Form 36 (SF-36) version 2, European quality of life questionnaire-5 dimensions (EQ-5D), and chronic liver disease questionnaire (CLDQ). Intergroup score differences were detected with U tests. Factors with a significant effect on HRQoL were identified with Spearman correlational analyses. Patients with HB (both groups) had lower SF-36 scores than HCs (p < 0.01), with the exception of general health subscores. Patients with HB cirrhosis had the lowest scores in the EQ-5D visual analog scale (VAS) component. Furthermore, patients with HB cirrhosis had lower (p < 0.01) CLDQ scores than patients with CHB. In our HB patient cohort, disease stage and income level were the factors most associated with HRQoL variables; age, education level, and marital status were, each, also significantly associated with some HRQoL variables in patients with HB in our study (p < 0.05 or p < 0.01). HRQoL is diminished in patients with HB in southeastern China. Disease stage and income emerged as key determinants of HRQoL scores. Augmenting social and medical supports for patients with HB, especially those with a socioeconomic status and an advanced disease stage, may help to enhance HRQoL.

Evaluation of a new tuberculosis-related interferon gamma release assay for tuberculosis infection diagnosis in Huzhou, eastern China.

OBJECTIVE: To compare the performance of a new tuberculosis-related interferon gamma release assay (TB-IGRA) with that of QuantiFERON-TB Gold In-Tube (QFT-GIT) for TB infection diagnosis in China. MATERIALS AND METHODS: A total of 458 active TB patients and 378 healthy individuals were enrolled. Among the 458 active TB patients, 395 had pulmonary TB and 63 had extra-pulmonary TB. The blood samples were collected from the active TB patients and health controls; then TB-IGRA and QFT-GIT were used to detect interferon gamma (IFN-γ) levels. RESULTS: The sensitivity, specificity, positive predictive value, and negative predictive value in TB infection diagnosis for active TB by the TB-IGRA were 83.4%, 94.2%, 94.5%, and 82.4%, respectively. For QFT-GIT, the sensitivity, specificity, positive predictive value, and negative predictive value in TB infection diagnosis for active TB were 81.4%, 97.1%, 97.1%, and 81.2%, respectively. CONCLUSIONS: TB-IGRA had a high sensitivity and specificity for TB infection; it could be comparable with the QFT-GIT assay. It might be a powerful assisting tool for TB infection diagnosis in the Chinese clinical setting.
