[Research progress on the effect of common metabolism-related comorbidities on health outcomes and management strategies in patients with chronic hepatitis B].

With the increasing life expectancy and lifestyle changes of patients with chronic hepatitis B (CHB), the significance of comorbidities of chronic non-communicable diseases (NCDs) in disease progression and health prognosis of CHB patients is gaining prominence. This study aims to explore the association between CHB and NCDs comorbidities, focusing on the impact of common metabolism-related diseases, such as metabolic syndrome and diabetes, on the health outcomes of CHB patients. We also summarize studies on integrating the management of comorbidities in CHB patients and provide relevant recommendations for effective management. The findings of this study serve as a foundation for understanding the clinical characteristics and prevalence trends, reducing the disease burden of comorbidities among CHB patients, and establishing a comprehensive and coordinated management system for comorbidities.

[Real-world study of paritaprevir/ritonavir-ombitasvir combined with dasabuvir for the treatment of chronic hepatitis C 1b genotype infection in China].

Objective: To evaluate the real-world safety and curative effect of ombitasvir combined with dasabuvir for the treatment of chronic hepatitis C 1b genotype infection in non-cirrhotic or compensated cirrhotic patients. Methods: A real-world research method was adopted, and the research was conducted at three medical centers of mainland China. Non- cirrhotic or compensated cirrhotic patients with HCV genotype 1b infection who were initially treated with IFN/PEG-IFN-alpha combined with ribavirin, and ombitasvir combined with dasabuvir for 8 or 12 weeks were taken. Sustained virological response (SVR) and the incidence of adverse events during treatment and follow-up were evaluated after 12 weeks of drug withdrawal at OBV/PTV/r 25/150/100mg once daily and DSV 250mg, twice daily. Median and range were used for description of non-normally distributed data. Results: 80 cases of GT1b were included in this study. Of these 88.8% (71/80) were newly diagnosed, 12.5% (10/80) were compensated cirrhotic, 97.5% (78/80) received 12 weeks treatment, and 2.5% (2/80) received 8 weeks treatment. The rate of HCV RNA negative at EOT (end of treatment) was 100% (64/64). A total of 67 patients completed the treatment within 12 weeks, and 43 patients returned to the hospital for further consultations, and SVR12 was 100%(43/43). No patient discontinued the drugs because of an adverse event during treatment. Conclusion: In the real world, Ombitasvir combined with dasabuvir for the treatment of chronic hepatitis C 1b genotype infection in China has 100% rates of EOT and SVR12 with well- tolerability and safety.

Novel gain of function mutation in the SLC40A1 gene associated with hereditary haemochromatosis type 4.

Here we report the case of a 69-year-old Chinese Han woman who presented with liver cirrhosis, diabetes mellitus, skin hyperpigmentation, hyperferritinaemia and high transferrin saturation. Subsequent genetic analyses identified a novel heterozygous mutation (p.Cys326Phe) in the SLC40A1 gene. This is the first report regarding a SLC40A1 mutation in the Chinese Han population and provides novel clinical evidence for the importance of p.Cys326 in SLC40A1 gene function.
