Ferric citrate for the treatment of hyperphosphatemia and anemia in patients with chronic kidney disease: a meta-analysis of randomized clinical trials

BackgroundHyperphosphatemia and anemia, which are common complications of chronic kidney disease (CKD), can independently contribute to cardiovascular events. Several previous studies have found that the iron-based phosphate binder, ferric citrate (FC), could be beneficial to both hyperphosphatemia and anemia.MethodsRelevant literature from PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials (CCRCT) and MEDLINE databases were searched up to 21 February 2022, in order to conduct a meta-analysis to investigate the efficacy, safety and economic benefits of ferric citrate treatment in CKD patients with hyperphosphatemia and anemia. The meta-analysis was conducted independently by two reviewers using the RevMan software (version 5.3).ResultsIn total, this study included 16 randomized clinical trials (RCT) involving 1754 participants. The meta-analysis showed that ferric citrate could significantly reduce the serum phosphorus in CKD patients compared to the placebo control groups (MD −1.76 mg/dL, 95% CI (−2.78, −0.75); p = 0.0007). In contrast, the difference between ferric citrate treatment and active controls, such as non-iron-based phosphate binders, sevelamer, calcium carbonate, lanthanum carbonate and sodium ferrous citrate, was not statistically significant (MD − 0.09 mg/dL, 95% CI (−0.35, 0.17); p = 0.51). However, ferric citrate could effectively improve hemoglobin levels when compared to the active drug (MD 0.43 g/dL, 95% CI (0.04, 0.82); p = 0.03) and placebo groups (MD 0.39 g/dL, 95% CI (0.04, 0.73); p = 0.03). According to eight studies, ferric citrate was found to be cost-effective treatment in comparison to control drugs. Most of the adverse events (AE) following ferric citrate treatment were mild at most.ConclusionCollectively, our review suggests that iron-based phosphate binder, ferric citrate is an effective and safe treatment option for CKD patients with hyperphosphatemia and anemia. More importantly, this alternative treatment may also less expensive. Nevertheless, more scientific studies are warranted to validate our findings.     

胸主动脉腔内修复术采用裙边型烟囱支架（Longuette™）的PATENCY临床试验研究结果

背景与目的 烟囱技术是胸主动脉腔内修复术（TEVAR）中重建左锁骨下动脉（LSA）的方法,Ⅰa型内漏是其主要并发症。裙边型烟囱支架（Longuette?）专为烟囱技术设计,用于重建LSA时降低Ⅰa型内漏。为评估Longuette?烟囱支架联合TEVAR治疗累及LSA的Stanford B型主动脉夹层（TBAD）的疗效,笔者开展了前瞻性、多中心临床试验（PATENCY临床试验）。本研究总结PATENCY临床试验的1年结果和经验。方法 2018年10月—2022年3月,全国26家血管外科中心参与PATENCY临床试验,共纳入150例符合标准的TBAD患者。所有患者均在TEVAR术中采用Longuette?烟囱支架重建LSA。评估患者围手术期和术后12个月的临床效果和不良事件,并分析患者术后1年累积生存率、LSA通畅率和无内漏率。结果 患者年龄30~77岁,平均（54.48±11.12）岁,138例（92.0%）患者合并高血压病;急性、亚急性和慢性TBAD分别占74.7%,17.3%和8.0%。124例（82.7%）患者采用全身麻醉。手术成功率为99.33%（149/150）,手术时间（91.67±41.47）min,X线暴露时间（31.36±16.71）min,手术出血量为（71.55±60.40）mL。围手术期内漏发生率为5.33%（8/150）,包括Ⅰ型6例、Ⅱ型1例、Ⅳ型1例;1例（0.67%）患者发生Longuette?烟囱支架急性闭塞,再次实施腔内手术后恢复通畅;1例（0.67%）患者术后发生急性脑梗死;2例（1.33%）患者术后发生逆撕的Stanford A型主动脉夹层,其中1例术后3周死亡。术后30 d死亡2例（1.33%）。142例患者进行了密切随访,随访时间为11.67（5~16）个月。无主动脉支架和Longuette?烟囱支架移位。2例Ⅰ型内漏患者分别于术后6个月和1年进行了再次介入栓塞手术治疗,术后1年随访仍有6例患者有轻微的内漏持续存在,患者TBAD假腔保持稳定,无明显症状,均予以保守治疗。Longuette?烟囱支架内狭窄和闭塞分别发生1例和2例,逆撕的Stanford A型主动脉夹层患者1例,假腔增大,患者均无明显症状,予以保守治疗。无发生脑卒中、截瘫、左上肢缺血等并发症。术后12个月累积生存率、LSA通畅率、无内漏率分别为97.96%、97.96%和91.91%。结论 采用Longuette?烟囱支架在TBAD腔内治疗中重建LSA简便、安全、有效,其能够有效降低围手术期Ⅰa型内漏的发生率,为微创治疗主动脉弓部病变提供新的治疗方式。

Comparing the efficacy of different intra-articular injections for knee osteoarthritis: A network analysis

Background:The findings on the effectiveness of platelet-rich plasma, ozone, and hyaluronic acid in the treatment of osteoarthritis of the knee are controversial, and the existing original studies and meta-analyses are mostly comparisons of a single joint cavity injection method, lacking direct and indirect comparisons of different drugs in the joint cavity. The lack of direct and indirect comparisons of different drugs in the joint cavity makes it difficult to have a clearer and more comprehensive understanding of joint cavity injection methods. In this study, the efficacy of platelet-rich, ozone, sodium hyaluronate, and combined knee cavity injections were compared directly or indirectly using a reticulated meta-analysis in this field, and the efficacy of treatment measures was ranked to provide more comprehensive and reliable evidence-based clinical evidence for the selection of knee cavity injections in osteoarthritis of the knee.Objective:To compare the effects of platelet-rich plasma, ozone, and sodium glassate injection interventions on the efficacy of osteoarthritis of the knee through reticulated Meta-analysis, and to comprehensively compare the clinical effectiveness of platelet-rich plasma, ozone, and sodium glassate injection joint cavity injection for the treatment of osteoarthritis of the knee.Methods:The PubMed, CBM, CNKI, VIP, and Wan-Fang databases were searched for information on the effectiveness of platelet-rich plasma, ozone, and sodium vitrate injection for the comparative treatment of osteoarthritis of the knee, with a search time frame of each database from the date of creation to July 20, 2021. Two investigators independently screened the literature, extracted data according to inclusion and exclusion criteria, and evaluated the quality of the literature in parallel. Statistical analysis was performed using Stata 16.0 software to compare the differences in the efficacy of each treatment measure using the ratio and 95% confidence interval as effect indicators and to rank the efficacy.Results:Thirty-three RCTs with 7003 patients with osteoarthritis of the knee were included, involving 5 therapeutic measures. Meta-analysis showed that the efficacy of platelet-rich plasma injection was superior to both ozone and hyaluronic acid therapies. Hyaluronic acid+ozone and platelet-rich plasma+hyaluronic acid were both superior to ozone and hyaluronic acid monotherapy. The differences in efficacy between hyaluronic acid and ozone compared with platelet-rich plasma were statistically significant, and the differences in efficacy between the 2 combination therapies (platelet-rich plasma+hyaluronic acid, hyaluronic acid+ozone) and the 3 monotherapies (platelet-rich plasma, ozone, hyaluronic acid) were statistically significant. Platelet-rich plasma+hyaluronic acid, hyaluronic acid+ozone compared with 3 monotherapies (platelet-rich plasma, ozone, hyaluronic acid) were statistically significant, except for the difference in efficacy with platelet-rich plasma, which was not statistically significant, indicating that this platelet-rich plasma+hyaluronic acid and Hyaluronic acid+ozone combination therapy was superior to monotherapy. Also, the efficacy of platelet-rich plasma was better than hyaluronic acid and ozone and the difference was statistically significant, indicating that platelet-rich plasma was more effective than ozone and sodium glass in the treatment of osteoarthritis of the knee in monotherapy.Conclusion:It is believed that in the course of clinical practice, hyaluronic acid+ozone or platelet-rich plasma+hyaluronic acid combination therapy or platelet-rich plasma therapy can be preferred for patients with osteoarthritis of the knee.
