RESUMO
Background: While hyperuricemia has been correlated with cardiovascular (CV) diseases, further evidence is required to evaluate the implications of stable serum uric acid (sUA) levels, especially concerning low sUA. This study aimed to investigate prolonged stable sUA levels and CV events/mortality. Methods: We conducted a retrospective cohort study at a medical center using electronic medical records linked with the national claims database. Patients with at least two sUA measurements, with intervals ranging from 6 months to 4 years, were included. The mean of the first two eligible sUA measurements were analyzed, stratified by sex. Outcomes of interest comprised major adverse cardiovascular events (MACE), heart failure hospitalization, CV and all-cause mortality. Results: This study included 33,096 patients (follow-up: men 6.6 years, women 6.4 years). After multivariable adjustment, cubic spline models showed that long-term high sUA levels were consistently associated with a higher risk of MACE, heart failure hospitalization, CV and all-cause mortality. A U-shaped association was observed between sUA levels and all-cause mortality in both sexes and between sUA levels and CV mortality in women. The impact of sUA, especially lower levels, on CV events and mortality was more pronounced in women than in men. Conclusion: Long-term high sUA levels are consistently associated with increased risk of CV events and mortality. A U-shaped association between sUA levels and all-cause mortality was observed in both men and women and was pronounced in women. The findings underscore the importance of considering sUA levels, especially in women, when assessing CV risk.
RESUMO
BACKGROUND AND AIMS: This study aimed to update the epidemiology, clinical, and economic outcomes of patients diagnosed with chronic hepatitis B (CHB) infection in Taiwan. METHODS: This is a retrospective observational study using claims data from the National Health Insurance Research Database. Cases were identified between 2010 and 2019 using CHB diagnosis codes and claims for alanine aminotransferase laboratory tests or CHB treatment within one year of the first CHB diagnosis. Patient characteristics, epidemiology, clinical, and economic outcomes were described. RESULTS: A total of 730 154 CHB-diagnosed cases were identified. The prevalence of diagnosed CHB increased from 1.13% in 2010 to 2.43% in 2019, with the highest occurring among those aged 55-64 years (4.76%) and 45-54 years (4.37%) and being higher in men (2.98%) than in women (2.21%). The majority of newly diagnosed CHB patients were 35 years of age or older (86.6%), with a median age of 49 years. After a median follow-up period of 6.42 years, 12.5%, 7.9%, 2.8%, and 0.35% were diagnosed with cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and liver transplantation respectively. Among 456 706 incident CHB-diagnosed patients, 17.4% had received at least one CHB medication, with the majority taking entecavir (67.9%). Patients with increasing disease severity had higher healthcare resource utilization, and inpatient costs accounted for 48.9%-65.5% of the overall medical cost in different health states. CONCLUSION: Despite the decreasing incidence of newly diagnosed CHB, the prevalence of diagnosed CHB remains high and poses a significant healthcare challenge owing to the high economic burden associated with the complications of CHB.

Colistin is the last-resort antimicrobial agent against infections caused by multidrug-resistance Gram-negative bacteria (MDR-GNB). However, a differing risk of colistin-associated acute kidney injury (CA-AKI) has been demonstrated without affecting mortality, thus the association and its importance needs to be questioned. To assess the impact of this adverse effect, a meta-analysis comparing colistin with other antibiotics in treating MDR-GNB infections was conducted. The PubMed, Embase and Cochrane Library electronic databases were searched up to 31 December 2018 for cohort studies and randomised controlled trials with at least two arms with one arm containing colistin-based treatment. The primary endpoint was the incidence of AKI. The secondary endpoint was 30-day all-cause mortality. A total of 34 studies, including 26 regarding colistin-based therapy versus other antibiotics and 9 regarding colistin monotherapy versus combination therapy, were included. The incidence of CA-AKI was 32.3%. Colistin was associated with an 82% higher incidence of AKI than other antibiotics [odd ratio (OR) = 1.82, 95% confidence interval (CI) 1.13-2.92; P = 0.01]. Most CA-AKI events were mild and reversible without a higher rate of mortality or the requirement for renal replacement therapy (RRT). Only 1.0% of patients required RRT for > 4 weeks. Compared with colistin monotherapy, combination therapy was associated with a significantly lower incidence of AKI (OR = 1.46, 95% CI 1.10-1.94; P = 0.009), particularly in combination with a carbapenem (OR = 1.97, 95% CI 1.30-2.99; P = 0.001). In conclusion, CA-AKI might not be an important limitation of colistin in MDR-GNB therapy.
