RESUMO
Major depressive disorder (MDD) is considered as a risk factor for osteoporosis. Bone mineral density (BMD), as the main tool for diagnosing osteoporosis, has been reported to have correlation with MDD in different cohorts. However, the information in causative link and etiology determinants of osteoporosis in MDD is still under investigation. The results are unclear. Thus, we perform a meta-analysis to evaluate the association between altered BMD and MDD. We searched the electronic databases to find studies examining BMD in patients with MDD. Finally, 26 published studies were included in our meta-analysis up from January 1990 to January 2019. All the data were pooled analysis using RevMan software. The association between altered BMD and MDD was assessed by std. mean difference (STD) and their 95% confidence intervals (CIs) for each study. Twenty-six studies were included in this meta-analysis. Pooled results showed a significant lower BMD in spine (STD=0.51, 95% CI=0.30-0.71, p < .00001), total hip (STD=0.41, 95% CI=0.16 to 0.66, p = .001), and femoral neck (STD=0.93, 95% CI=0.32 to 1.55, p = .003) in MDD compared with controls. After stratification by mean age, gender, recruitment, diagnostic criteria, and measuring methods, no significant difference of BMD was found in bone mineral density of male total hip between MDD and controls(p > .05). Moreover, adults appear to have lower BMD than old cohorts. This is an updated meta-analysis to reveal the association of bone mineral density and depression, suggesting that BMD appears to be more susceptible to occur in spine, total hip, femoral neck in MDD, especially for adults and women. Our meta-analysis may provide clinicians and public health administrators with an important screening tool for assessing depression and avoiding osteoporosis in adult subjects and female.
RESUMO
PURPOSE: HIF-PHI (hypoxia-inducible factor prolyl hydroxylase inhibitor) was developed to improve renal anemia. This study was to evaluate the efficiency and safety of HIF-PHI in patients with non-dialysis-dependent chronic kidney disease (NDD-CKD). METHODS: The literature was extracted from PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and the Wanfang database. Statistical tests and forest plots were depicted by Review Manager Version 5.3. The primary outcome was a change in hemoglobin level from baseline (ΔHb). Secondary outcomes were changes in ferritin (ΔFerritin), hepcidin (ΔHepcidin), and transferrin saturation from baseline (ΔTSAT), and adverse events (AEs). This study is registered with PROSPERO (registration number CRD42020199656). RESULTS: Ten trials were included. The results showed that HIF-PHI improved the ΔHb [SMD 3.03 (95% CI 2.10, 3.96), P < 0.00001] in NDD patients. HIF-PHI reduced hepcidin levels in the NDD patients [SMD - 1.44 (95% CI - 2.19-0.70), P = 0.0002]. ΔFerritin values were reduced significantly in the HIF-PHI group [SMD - 1.08 (95% CI - 1.63-0.53), P = 0.0001]. However, ΔTSAT values showed no significant difference in the HIF-PHI group compared to the placebo group [SMD - 0.23 (95% CI - 0.66-0.21), P = 0.31]. In the safety assessment, HIF-PHI did not increase adverse events significantly [RR 0.98 (95% CI 0.88-1.10), P = 0.74]. CONCLUSION: HIF-PHI improves renal anemia and iron utilization disorder in NDD-CKD patients, without significantly more adverse events.
