Cytopenias among patients with rheumatic diseases using methotrexate: a meta-analysis of randomized controlled clinical trials.

ABSTRACT: OBJECTIVE:To conduct a systematic literature review and meta-analysis to estimate the incidence of anaemia, leucopoenia, neutropenia and thrombocytopenia associated with MTX plus folic acid among patients with rheumatic diseases. METHODS:We searched MEDLINE, PubMed and EMBASE through August 2016 for all randomized controlled clinical trials with a MTX monotherapy arm. We excluded randomized controlled clinical trials for cancer and included only double-blind studies that reported on haematologic adverse events. Studies were excluded if patients did not receive folic acid or leucovorin supplementation. Full text articles were assessed by two independent reviewers. Incidence estimates were calculated using random-effects models. RESULTS:Of 1601 studies identified, 30 (1.87%) were included, representing 3858 patients; all had RA. Seventeen trials reported on anaemia (n = 2032), 17 reported on leucopoenia (n = 2220), 16 reported on neutropenia (n = 2202) and 12 reported on thrombocytopenia (n = 1507). The incidence for any anaemia was 2.55% (95% CI 0.60-5.47%), any leucopoenia 1.17% (95% CI 0.16-2.80%), any neutropenia 1.77% (95% CI 0.33-4.00%), and any thrombocytopenia 0.19% (95% CI 0.00-0.86%). Four cases of severe anaemia were reported, as defined by authors, along with three cases of severe neutropenia. No cases of severe leucopoenia, severe thrombocytopenia or pancytopenia were reported. CONCLUSION:Cytopenias are an uncommon side effect of low-dose MTX with folic acid supplementation among RA patients. Further research is needed to reach a more precise estimate.

Project description:Multiple randomized controlled trials of remote ischemic preconditioning (RIPC) prior to cardiac surgery have failed to demonstrate clinical benefit. The aim of this updated meta-analysis was to evaluate the effect of RIPC on outcomes following cardiac surgery.Searches of PubMed, Cochrane, EMBASE, and Web of Science databases were performed for 1970 to December 13, 2015. Randomized controlled trials comparing RIPC with a sham procedure prior to cardiac surgery performed with cardiopulmonary bypass were assessed. All-cause mortality, acute kidney injury (AKI), and myocardial infarction were the primary outcomes of interest. We identified 21 trials that randomized 5262 patients to RIPC or a sham procedure prior to undergoing cardiac surgery. The majority of patients were men (72.6%) and the mean or median age ranged from 42.3 to 76.3 years. Of the 9 trials that evaluated mortality, 188 deaths occurred out of a total of 4210 randomized patients, with 96 deaths occurring in 2098 patients (4.6%) randomized to RIPC and 92 deaths occurring in 2112 patients (4.4%) randomized to a sham control procedure, demonstrating no significant reduction in all-cause mortality (risk ratio [RR], 0.987; 95% CI, 0.653-1.492, P=0.95). Twelve studies evaluated AKI in 4209 randomized patients. In these studies, AKI was observed in 516 of 2091 patients (24.7%) undergoing RIPC and in 577 of 2118 patients (27.2%) randomized to a sham procedure. RIPC did not result in a significant reduction in AKI (RR, 0.839; 95% CI, 0.703-1.001 [P=0.052]). In 6 studies consisting of 3799 randomized participants, myocardial infarction occurred in 237 of 1891 patients (12.5%) randomized to RIPC and in 282 of 1908 patients (14.8%) randomized to a sham procedure, resulting in no significant reduction in postoperative myocardial infarction (RR, 0.809; 95% CI, 0.615-1.064 [P=0.13]). A subgroup analysis was performed a priori based on previous studies suggesting that propofol may mitigate the protective benefits of RIPC. Three studies randomized patients undergoing cardiac surgery to RIPC or sham procedure in the absence of propofol anesthesia. Most of these patients were men (60.3%) and the mean or median age ranged from 57.0 to 70.6 years. In this propofol-free subgroup of 434 randomized patients, 71 of 217 patients (32.7%) who underwent RIPC developed AKI compared with 103 of 217 patients (47.5%) treated with a sham procedure. In this cohort, RIPC resulted in a significant reduction in AKI (RR, 0.700; 95% CI, 0.527-0.930 [P=0.014]). In studies of patients who received propofol anesthesia, 445 of 1874 (23.7%) patients randomized to RIPC developed AKI compared with 474 of 1901 (24.9%) who underwent a sham procedure. The RR for AKI was 0.928 (95% CI, 0.781-1.102; P=0.39) for RIPC versus sham. There was no significant interaction between the two subgroups (P=0.098).RIPC does not reduce morbidity or mortality in patients undergoing cardiac surgery with cardiopulmonary bypass. In the subgroup of studies in which propofol was not used, a reduction in AKI was seen, suggesting that propofol may interact with the protective effects of RIPC. Future studies should evaluate RIPC in the absence of propofol anesthesia.

Project description:BackgroundMethotrexate (MTX) is the most commonly prescribed disease-modifying drug in the treatment of rheumatic diseases. Regular laboratory testing is recommended to recognize side effects, such as hepatotoxicity and myelotoxicity as well as decreases in renal function that may cause toxic MTX accumulation. Additionally, folic acid is recommended as prophylaxis against specific side effects. In this study we investigated whether laboratory monitoring and prescription of folic acid took place according to published recommendations.Material and methodsClaims data from the statutory health insurance from 1 January 2009 to 31 December 2013 were retrospectively analyzed. A total of 40,087 adults with a rheumatic diagnosis (ICD10 codes M05-M18), no malignant disease and no previous MTX prescription within 12 months were extracted from the InGef (Institute for Applied Health Research in Berlin, formerly Health Risk Institute) research database. The frequency of recommended laboratory testing, appointments with rheumatologists and the prescription of folic acid prophylaxis were investigated.ResultsOf the patients 12,451 began treatment with MTX in the observation period. Between 42% and 46% of recommended blood counts, liver values and kidney function tests and 14% of urinalyses were performed according to recommendations. Of the patients 84% were seen regularly by a rheumatologist and 74% received a prescription for prophylactic folic acid. Serious conditions potentially resulting from MTX treatment were observed in 0.7-3.5 cases/1000 person years.DiscussionLaboratory monitoring in the context of MTX treatment is carried out less frequently than recommended in the literature. Potential MTX-associated serious complications are rare from a practice perspective. On the one hand solutions are needed for a better coordination of laboratory monitoring. On the other hand more empirical evidence is needed regarding the benefits of laboratory monitoring and the appropriate intervals thereof.
