Infliximab in neurosarcoidosis: a systematic review and meta-analysis.

ABSTRACT:

Objectives

To evaluate the clinical outcomes and relapse rates in neurosarcoidosis patients administered infliximab.

Methods

A systematic review was conducted using the MEDLINE, EMBASE, SCOPUS, and Cochrane Library databases. The search included studies from their inception to March 2023. We included case-series studies with at least 10 neurosarcoidosis patients undergoing any treatment type. Studies were also required to report at least one of the following outcomes: response rate, overall survival rate, or relapse rate. This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A random-effects model facilitated the analysis of proportional treatment outcomes. Study quality was evaluated using the modified Newcastle-Ottawa quality assessment scale, while a funnel plot helped detect any publication bias.

Results

Seven studies comprising 237 patients with neurosarcoidosis were included in the analysis. Of these patients, 184 (77.6%) received treatment with infliximab. The pooled proportion of patients showing clinical improvement after infliximab treatment was 0.74 (95% CI 0.64-0.84, I² = 49.73%). Relapse rates, derived from four studies, stood at 0.38 (95% CI 0.22-0.55, I² = 56.92%). Most studies reported successful tapering or cessation of corticosteroid dosage in patients receiving infliximab. Adverse effects were reported in 52 (29.4%) patients, of which 39 out of 54 events (72.2%) were linked to infections.

Interpretation

Infliximab demonstrated potential improvement in clinical outcomes for patients with refractory neurosarcoidosis and showed potential for reducing the dosage of concurrent corticosteroids. However, a degree of relapse was observed, with infections being the primary concern for adverse events.

Project description:BackgroundKawasaki disease (KD) is a self-limited illness that results in coronary artery aneurysms (CAAs) and threatens children's health and lives. The therapeutic effects of single intravenous immunoglobulin gamma (IVIG) vs. infliximab (IFX) (with or without IVIG) in young children with KD remain unclear. Thus, we made a meta-analysis and systematic review, including all of the studies which have evaluated the effectiveness and safety of IFX and IVIG KD patients.MethodsThe databases of the Cochrane Library, PubMed and Embase websites were searched for articles appearing from inception until December 31, 2020. Clinical studies that compared IFX either as initial therapy plus IVIG or rescue therapy after IVIG (IFX group) failure compared with IVIG treatment alone (IVIG group) in treating KD patients were included.ResultsThe meta-analysis included nine studies characterizing 712 patients. The treatment response was significantly higher in the adjunctive IFX therapy group than in the IVIG therapy group [odds ratio (OR) 2.64; 95% CI: 1.52-4.59; P=0.0005]. Subgroup analysis, the effect of IFX therapy on treatment response is more effectiveness in the group of the high-risk KD patients than IVIG therapy (OR 6.07; 95% CI: 2.30-16.04; P=0.0003; random-effects model). Further analysis showed no difference in the improvement of CAAs in short-term follow-up between the two groups. However, adding IFX either as initial therapy or as additional therapy all showed an advantageous effect regarding the ∆Z score of the left anterior descending (LAD) (MD =0.29; 95% CI: 0.27-0.31; P<0.00001) and right coronary artery (RCA) (MD =0.24; 95% CI: 0.22-0.26; P<0.00001). Further, IFX exhibited significant effect on the treatment response compared with IVIG therapy in the Asian group (OR, 2.84; 95% CI: 1.51-5.36; P=0.001; random-effects model), and the beneficial effects of IFX were given without increasing the risk of AEs.ConclusionsThis meta-analysis emphasizes the importance of IFX on the treatment response in the high-risk KD patients. IFX may play a role in the Asian KD patients and prevention of progressive CAA, and does not increase the risk of AEs in KD patients.

Project description:BackgroundCrohn disease is an inflammatory bowel disease with intermittent symptoms relating to damage to the gastrointestinal tract. Compared with adult-onset Crohn disease, the childhood-onset form is more likely to be severe. Infliximab has shown efficacy in adult patients.ObjectiveTo examine the efficacy and safety of infliximab in pediatric Crohn disease, by means of a systematic review.Data sourcesThree databases (MEDLINE, Embase, and Cochrane Central Register of Controlled Trials) and regulatory documents were searched from inception to December 2017. Clinical trial registries, conference abstracts, and reference lists were searched to March 2018.Study selection and data extractionRandomized controlled trials (RCTs) and prospective cohort studies that compared infliximab with active control were included in the analysis. Two reviewers independently performed screening, extracted data, and assessed risk of bias. The primary outcomes were induction and maintenance of endoscopic remission and severe adverse effects.Data synthesisThree eligible RCTs comparing different dose regimens, 16 prospective cohort studies comparing infliximab with other therapies (adalimumab, exclusive enteral nutrition, or standard of care), and 3 prospective cohort studies comparing different infliximab regimens were identified. Meta-analysis of the RCTs showed no significant difference between infliximab every 8 weeks compared with longer intervals for maintenance of clinical remission (risk ratio [RR] 1.76, 95% confidence interval [CI] 0.98-3.19). Meta-analyses of the prospective cohort studies showed no significant differences between infliximab and adalimumab for maintenance of endoscopic remission (RR 1.07, 95% CI 0.60-1.92), between infliximab and exclusive enteral nutrition for induction of clinical remission (RR 1.09, 95% CI 0.82-1.45), or between infliximab and standard of care for maintenance of clinical remission at 6 and 12 months (RR 1.12, 95% CI 0.58-2.17, and RR 1.24, 95% CI 0.84-1.84, respectively).ConclusionsCurrent evidence suggested comparable efficacy for infliximab and other therapies; however, the available literature was limited by risk of bias and small sample size. Further prospective studies are needed to confirm the efficacy and safety of this drug in pediatric Crohn disease.
