Albendazole and Corticosteroids for the Treatment of Solitary Cysticercus Granuloma: A Network Meta-analysis.

ABSTRACT:

Background

Solitary cysticercus granuloma (SCG) is the commonest form of neurocysticercosis in the Indian subcontinent and in travelers. Several different treatment options exist for SCG. We conducted a Bayesian network meta-analysis of randomized clinical trials (RCTs) to identify the best treatment option to prevent seizure recurrence and promote lesion resolution for patients with SCG.

Methods and principal findings

PubMed, EMBASE and the Cochrane Library databases (up to June 1, 2015) were searched for RCTs that compared any anthelmintics or corticosteroids, alone or in combination, with placebo or head to head and reported on seizure recurrence and lesion resolution in patients with SCG. A total of 14 RCTs (1277 patients) were included in the quantitative analysis focusing on four different treatment options. A Bayesian network model computing odds ratios (OR) with 95% credible intervals (CrI) and probability of being best (Pbest) was used to compare all interventions simultaneously. Albendazole and corticosteroids combination therapy was the only regimen that significantly decreased the risk of seizure recurrence compared with conservative treatment (OR 0.32, 95% CrI 0.10-0.93, Pbest 73.3%). Albendazole and corticosteroids alone or in combination were all efficacious in hastening granuloma resolution, but the combined therapy remained the best option based on probability analysis (OR 3.05, 95% CrI 1.24-7.95, Pbest 53.9%). The superiority of the combination therapy changed little in RCTs with different follow-up durations and in sensitivity analyses. The limitations of this study include high risk of bias and short follow-up duration in most studies.

Conclusions

Dual therapy of albendazole and corticosteroids was the most efficacious regimen that could prevent seizure recurrence and promote lesion resolution in a follow-up period of around one year. It should be recommended for the management of SCG until more high-quality evidence is available.

Project description:A major source of epilepsy is Neurocysticercosis (NCC), caused by Taenia solium infection. Solitary cysticercus granuloma (SCG), a sub-group of NCC induced epilepsy, is the most common form of NCC in India. Current diagnostic criteria for SCG epilepsy require brain imaging which may not be available in communities where the disease is endemic. Identification of serum changes and potential biomolecules that could distinguish SCG epilepsy from idiopathic generalized epilepsy (IE), without the initial need for imaging, could assist in disease identification, understanding, and treatment. The objective here was to investigate, using mass spectrometry (MS), sera biomolecule differences between patients with SCG epilepsy or IE to help distinguish these disorders based on physiological differences, to understand underlying phenotypes and mechanisms, and to lay ground work for future therapeutic and biomarker analyses. Sera were obtained from patients with SCG or IE (N = 29 each group). Serum mass peak profiling was performed with electrospray ionization (ESI) MS, and mass peak area means in the two groups were compared using leave one [serum sample] out cross validation (LOOCV). Serum LOOCV analysis identified significant differences between SCG and IE patient groups (p = 10-20), which became non-significant (p = 0.074) when the samples were randomly allocated to the groups and reanalyzed. Tandem MS/MS peptide analysis of serum mass peaks from SCG or IE patients was performed to help identify potential peptide/protein biochemical and phenotypic changes involving these two forms of epilepsy. Bioinformatic analysis of these peptide/protein changes suggested neurological, inflammatory, seizure, blood brain barrier, cognition, ion channel, cell death, and behavior related biochemical systems were being altered in these disease states. This study provides groundwork for aiding in distinguishing SCG and IE patients in minimally invasive, lower-cost manners, for improving understanding of underlying epilepsy mechanisms, and for further identifying discriminatory biomarkers and potential therapeutic targets.

Project description:IntroductionInternal temporomandibular joint (TMJ) disorders are present in approximately 80% of patients with symptomatic temporomandibular disorders. Among the minimally invasive therapies, we find the intra-articular infiltration of substances, such as corticosteroids, hyaluronic acid or platelet-rich plasma accompanied or not by an arthrocentesis. There are several studies on minimally invasive therapy for internal TMJ disorders; however, none compares the effectiveness of the different intra-articular corticosteroids to each other.The purpose of this study is to evaluate the effectiveness of the different intra-articular corticosteroids for the treatment of internal disorders of the TMJ and compare them to each other or to other minimally invasive therapies.Methods and analysisA systematic search will be carried out up to December 2019 in the electronic databases: Medline, Cochrane Library, EMBASE, SCOPUS and LILACS.Randomised clinical trials evaluating patients with internal disorders of the TMJ, with intra-articular corticosteroid therapy and comparing these to each other and/or to other minimally invasive therapy will be included. The main outcomes will be pain and range of motion measured through validated scales.Two review authors will independently screen search results, extract data from included studies and assess the risk of bias in those studies using the Revised Cochrane Risk of Bias Tool (RoB 2.0). In the case of any discrepancy and failure to reach consensus, this will be resolved by a third reviewer.A network meta-analysis will be conducted based on direct comparisons to generate indirect comparisons of the different treatments. Data will be combined in a meta-analysis using a random effects model.The principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system will be used to assess the overall quality of the body of evidence associated with the main results.Ethics and disseminationThis protocol will not require ethical approval. The results of this review will be disseminated through peer-reviewed publications.Trial registration numberCRD42019129014.

Project description:Conventional systematic reviews have indicated that corticosteroids might result in a slight reduction in mortality in sepsis. However, the efficacy, safety, and optimal regimen of different corticosteroids partly remain unknown. In this study, we conducted a Bayesian network meta-analysis for a head-to-head comparison of the therapeutic efficacy and safety of currently used corticosteroids in sepsis. Design:A Bayesian network meta-analysis for a head-to-head comparison of the therapeutic efficacy and safety of currently used corticosteroids in sepsis. Setting:A total of 35 eligible randomized controlled trials of corticosteroid use in sepsis. Patients:The present Bayesian network meta-analysis included 8,859 patients with sepsis. Interventions:Randomized controlled trials were screened from PubMed, Embase, and the Cochrane Library up to December 28, 2019. A head-to-head comparison of the therapeutic efficacy and safety between the different categories of corticosteroids from the trials was conducted by Bayesian network meta-analysis. An empirical Bayesian meta-regression and a post hoc Bayesian network meta-analysis were performed to explore the appropriate dose and therapeutic duration of steroids for sepsis. Measurements and Main Results:A total of 35 randomized controlled trials including 8,859 patients with sepsis were enrolled in the final analysis. Bayesian network meta-analysis revealed that methylprednisolone and dexamethasone might be more effective in reducing short-term mortality in sepsis than placebo: methylprednisolone versus placebo (relative risk, 0.65, 95% credible interval 0.40-0.93), dexamethasone versus placebo (relative risk, 0.42, 95% credible interval, 0.24-0.84). Hydrocortisone and hydrocortisone plus fludrocortisone were superior to placebo in days to shock resolution (e-Table 5, Supplemental Digital Content 1, http://links.lww.com/CCX/A150): hydrocortisone versus placebo (mean difference, -1.70, 95% credible interval, -2.83 to -0.92), hydrocortisone plus fludrocortisone versus placebo (mean difference, -2.54, 95% credible interval, -4.19 to -0.84). Hydrocortisone was superior to placebo in reducing the length of stay in the ICU (mean difference, -1.43, 95% credible interval, -3.36 to -0.15). Methylprednisolone was superior to placebo in improving ventilation-free days (mean difference, 7.71, 95% credible interval, 1.15-14.42). In addition, further analysis indicated that the optimal therapeutic dosage was 200-400?mg per day of hydrocortisones or equivalents (relative risk, 0.83, 95% credible interval, 0.64-0.98), and the appropriate therapeutic duration was 4-7 days (relative risk, 0.78; 95% credible interval, 0.57-0.96). Conclusions:This study provided moderate evidence that the dosage of 200-400?mg per day of hydrocortisone or equivalent for 4-7 days was most likely to benefit septic patients.

Project description:Objective To estimate the benefits and harms of using corticosteroids as an adjunct treatment for sore throat.Design Systematic review and meta-analysis of randomised control trials.Data sources Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), trial registries up to May 2017, reference lists of eligible trials, related reviews.Study selection Randomised controlled trials of the addition of corticosteroids to standard clinical care for patients aged 5 or older in emergency department and primary care settings with clinical signs of acute tonsillitis, pharyngitis, or the clinical syndrome of sore throat. Trials were included irrespective of language or publication status.Review methods Reviewers identified studies, extracted data, and assessed the quality of the evidence, independently and in duplicate. A parallel guideline committee (BMJ Rapid Recommendation) provided input on the design and interpretation of the systematic review, including the selection of outcomes important to patients. Random effects model was used for meta-analyses. Quality of evidence was assessed with the GRADE approach.Results 10 eligible trials enrolled 1426 individuals. Patients who received single low dose corticosteroids (the most common intervention was oral dexamethasone with a maximum dose of 10 mg) were twice as likely to experience pain relief after 24 hours (relative risk 2.2, 95% confidence interval 1.2 to 4.3; risk difference 12.4%; moderate quality evidence) and 1.5 times more likely to have no pain at 48 hours (1.5, 1.3 to 1.8; risk difference 18.3%; high quality). The mean time to onset of pain relief in patients treated with corticosteroids was 4.8 hours earlier (95% confidence interval -1.9 to -7.8; moderate quality) and the mean time to complete resolution of pain was 11.1 hours earlier (-0.4 to -21.8; low quality) than in those treated with placebo. The absolute pain reduction at 24 hours (visual analogue scale 0-10) was greater in patients treated with corticosteroids (mean difference 1.3, 95% confidence interval 0.7 to 1.9; moderate quality). Nine of the 10 trials sought information regarding adverse events. Six studies reported no adverse effects, and three studies reported few adverse events, which were mostly complications related to disease, with a similar incidence in both groups.Conclusion Single low dose corticosteroids can provide pain relief in patients with sore throat, with no increase in serious adverse effects. Included trials did not assess the potential risks of larger cumulative doses in patients with recurrent episodes of acute sore throat.Systematic review registration PROSPERO CRD42017067808.

Project description:OBJECTIVE: To systematically review the efficacy of steroids in the prevention of acute respiratory distress syndrome (ARDS) in critically ill adults, and treatment for established ARDS. DATA SOURCES: Search of randomised controlled trials (1966-April 2007) of PubMed, Cochrane central register of controlled trials, Cochrane database of systematic reviews, American College of Physicians Journal Club, health technology assessment database, and database of abstracts of reviews of effects. DATA EXTRACTION: Two investigators independently assessed trials for inclusion and extracted data into standardised forms; differences were resolved by consensus. DATA SYNTHESIS: Steroid efficacy was assessed through a Bayesian hierarchical model for comparing the odds of developing ARDS and mortality (both expressed as odds ratio with 95% credible interval) and duration of ventilator free days, assessed as mean difference. Bayesian outcome probabilities were calculated as the probability that the odds ratio would be > or =1 or the probability that the mean difference would be > or =0. Nine randomised trials using variable dose and duration of steroids were identified. Preventive steroids (four studies) were associated with a trend to increase both the odds of patients developing ARDS (odds ratio 1.55, 95% credible interval 0.58 to 4.05; P(odds ratio > or =1)=86.6%), and the risk of mortality in those who subsequently developed ARDS (three studies, odds ratio 1.52, 95% credible interval 0.30 to 5.94; P(odds ratio > or =1)=72.8%). Steroid administration after onset of ARDS (five studies) was associated with a trend towards reduction in mortality (odds ratio 0.62, 95% credible interval 0.23 to 1.26; P(odds ratio > or =1)=6.8%). Steroid therapy increased the number of ventilator free days compared with controls (three studies, mean difference 4.05 days, 95% credible interval 0.22 to 8.71; P(mean difference > or =0)=97.9%). Steroids were not associated with increase in risk of infection. CONCLUSIONS: A definitive role of corticosteroids in the treatment of ARDS in adults is not established. A possibility of reduced mortality and increased ventilator free days with steroids started after the onset of ARDS was suggested. Preventive steroids possibly increase the incidence of ARDS in critically ill adults.
