BACKGROUND: Chronic kidney disease (CKD)-associated anemia (CKD-anemia) is associated with poor survival, and hemoglobin targets are often not achieved with current therapies. Phase 3 trials have demonstrated the treatment efficacy of roxadustat for CKD-anemia. This phase 4 study aims to evaluate the long-term (52-week) safety and effectiveness of roxadustat in a broad real-world patient population with CKD-anemia with and without dialysis in China. METHODS: This Phase 4 multicenter, open-label, prospective study, conducted from 24 November 2020 to 11 November 2022, evaluated the long-term safety and effectiveness of roxadustat for CKD-anemia in China. Patients aged ≥18 years with CKD-anemia with or without dialysis were included. The initial oral dose was 70-120 mg (weight-based followed by dose adjustment) over 52 weeks. The primary endpoint was safety based on adverse events (AEs). The secondary endpoints were hemoglobin changes from baseline and the proportion of patients who achieved mean hemoglobin ≥100 g/L. Effectiveness evaluable populations 1 (EE1) and EE2 included roxadustat-naïve and previously roxadustat-treated patients, respectively. The safety analysis set (SAF) included all patients who received ≥1 occasion. RESULTS: The EE1, EE2, and SAF populations included 1804, 193, and 2021 patients, respectively. In the SAF, the mean age was 50 ± 14 years, and 1087 patients (53.8%) were male. Mean baseline hemoglobin was 96.9 ± 14.0 g/L in EE1 and 100.3 ± 12.9 g/L in EE2. In EE1, the mean (95% confidence interval) hemoglobin changes from baseline over weeks 24-36 and 36-52 were 14.2 (13.5-14.9) g/L and 14.3 (13.5-15.0) g/L, respectively. Over weeks 24-36 and 36-52, 83.3% and 86.1% of patients in EE1 and 82.7% and 84.7% in EE2 achieved mean hemoglobin ≥100 g/L, respectively. In the SAF, 1643 (81.3%) patients experienced treatment-emergent AEs (TEAEs). Overall, 219 (10.8%) patients experienced drug-related TEAEs. Thirty-eight (1.9%) patients died of TEAEs (unrelated to the study drug). Vascular access thrombosis was uncommon. CONCLUSIONS: Roxadustat (52 weeks) increased hemoglobin and maintained the treatment target in Chinese patients with CKD-anemia with acceptable safety, supporting its use in real-world settings.

Objective To investigate the effects of remimazolam and propofol on postoperative nausea and vomiting(PONV)in patients undergoing painless prostate biopsy,so as to optimize the anesthesia protocols.Methods A retrospective analysis was conducted on the clinical data of 1217 patients who underwent painless prostate biopsy in our hospital during Jan.2023 and Jun.2024.Among them,1093 patients met the inclusion criteria and were divided into two groups:the remimazolam group(n=294)and the propofol group(n=799).After 1∶1 propensity score matching,with 267 patients in either group,a comparison was conducted regarding the incidence of PONV and anesthesia recovery time.Results Before propensity score matching,the remimazolam group had older age[66(53,83)years vs.63(49,78)years],higher body mass index(BMI)[25.30(21.83,29.23)vs.24.46(20.79,28.91)],larger intraoperative use of sufentanil[9(8,10)μg vs.7(6,9)μg],higher intraoperative use rate of ondansetron(55.4％vs.47.6％),and longer surgical duration[16(14,20)min vs.15(13,17)min],with statistically significant differences(P＜0.05).There were no statistically significant differences in the aforementioned factors between the two groups after propensity score matching(P＞0.05).Before propensity score matching,the incidence of PONV was higher in the remimazolam group than in the propofol group(17.7％vs.11.5％,P=0.007),while after propensity score matching,the incidence of PONV did not differ significantly between the two groups(12.7％vs.17.2％,P=0.146).Before and after propensity score matching,the anesthesia recovery time was significantly shorter in the remimazolam group than in the propofol group[3(2,4)min vs.7(4,10)min,P＜0.001].Conclusion Compared with propofol,remimazolam does not increase the incidence of PONV in patients undergoing painless prostate biopsy but can shorten anesthesia recovery time.

Objective To investigate the level of serum macrophage migration inhibitory factor (MIF) and its correlation with serum precollagen Ⅲ peptide (PⅢP) and tissue inhibitor of metalloproteinase (TIMP)-1 in patients with chronic hepatitis B (CHB) and hepatitis B virus (HBV)-related cirrhosis. Methods Forty-four CHB patients (hepatitis B group), 44 patients with HBV-related cirrhosis (cirrhosis group) and 30 healthy controls (control group) were enrolled in this study. The venous blood was collected and MIF level was detected by enzyme-linked immunosorbent assay (ELISA). Correlations between MIF and PⅢP, TIMP-1 were analyzed in observed groups. Comparison between groups was done using t test. The correlations between MIF level and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), plasma thromboplastin antecedent (PTA), PⅢP and TIMP-1 were analyzed by rectilinear correlation. Results The levels of serum MIF, PⅢP and TIMP-1 in CHB group and cirrhosis group were all significantly higher than those in control group (t=12.87,5.28, 10.98,t=11.22,14.84,11.17;all P<0.05), while there were no significant differences between CHB group and cirrhosis group (t= -1.05,1.52,--2.07;all P>0.05). There was no correlation between MIF level and ALT, AST, TBil and PTA. MIF level in CHB patients with hepatitis B e antigen (HBeAg) positive and high viral load were both higher than that in patients with HBeAg negative and low viral load. MIF level was both positively correlated with PⅢP level in CHB group and cirrhosis group (r=0. 603, P<0.05 and r=0. 415, P<0. 05, respectively). MIF level was also positively correlated with TIMP-1 level in CHB group (r=0. 458, P<0.05), while not correlated in cirrhosis group (r=0. 210, P>0.05). Levels of PⅢP and T1MP-1 were both correlated in CHB group and cirrhosis group (r=0. 849, P< 0.05 and r=0. 424, P<0.05, respectively). Conclusions The levels of serum MIF are significantly increased both in patients with CHB and cirrhosis. The early production of MIF might be related with viral replication, but not with liver function. MIF participates in formations of hepatitis, liver fibrosis and cirrhosis, which could reflect the degree of liver cirrhosis.
