Endobronchial Tuberculosis

Background: Corticosteroid exerts anti-inflammatory action and can prevent tissue damage resulting from various causes. Studies have shown that corticosteroids may prevent the damaging effect of tuberculosis (TB) in various organs, but there is no published meta-analysis specifically looking for the effect of corticosteroid in endobronchial TB. Objective: To synthesize the evidence regarding the usefulness of corticosteroid in endo-bronchial TB. Methods: A comprehensive search was performed of the major electronic databases till 30th November 2018. Randomized trials comparing treatment with corticosteroid as an adjunct to antitubercular drugs (ATT) versus placebo/no treatment in endobronchial TB were included. Three authors independently applied eligibility criteria, assessed the studies for methodological quality, and extracted data. The review is registered at PROSPERO database [CRD42016047063]. Results: Out of 525 search results, 4 trials including 205 patients (151 children) were eligible for inclusion. Oral prednisolone was used in various dose schedules. Rifampicin containing ATT regimen was used in 3 trials. The bronchoscopy findings showed no significant improvement at 1 month (effect size could not be calculated due to 0 event in the intervention group, p = 0.05), 2 months (RR 1.26, 95% CI 0.89 to 1.8), and at completion of ATT (RR 0.63, 95% CI 0.1 to 4.14) in steroid-treated group compared to the control group. The need for repeat bronchoscopy was significantly decreased in the steroid group (RR 0.13, 95% CI 0.02 to 0.9). Among the adverse events, the infection rate was significantly lesser in the steroid group (RR 0.53, 95% CI 0.29 to 0.97); but other adverse events (mortality, hypertension, and abdominal distension) showed no significant difference between the two groups. The GRADE evidence generated was of very low quality. Conclusions: The present meta-analysis showed that oral steroid does not help patients with endobronchial tuberculosis. However, the quality of evidence was very low. Future trials with robust design and a larger sample size would be required to provide any firm recommendation regarding the use of oral prednisolone in endobronchial tuberculosis.

Objective:To evaluate whether endovascular thrombectomy combined with intravenous thrombolysis is superior to the standard treatment of intravenous thrombolysis for the treatment of ischemic stroke.Methods:A meta-analysis of 12 studies obtained by searching PubMed and Web of Science database was performed to determine whether the difference in mortality (within 7 days or 90 days), functional outcome (modified Rankin Scale, 0-2), hemorrhage (symptomatic intracerebral hemorrhage, and subarachnoid hemorrhage), and recurrent ischemic stroke rate at 90 days between patients who underwent mechanical intravenous thrombolysis with (intervention) and without (control) endovascular thrombectomy.Results:As compared with the control group, patients in the intervention group had lower 90-day mortality [summary risk ratio (RR) = 0.83, 95% confidence interval (CI): 0.69-0.99; n = 1309/1070], higher recanalization rate (RR = 2.24, 95% CI: 1.97-2.56; n = 504/497), better functional outcome (modified Rankin score: 0-2; RR = 1.41, 95% CI: 1.29-1.54; n = 1702/1502), and higher rate of subarachnoid hemorrhage (RR = 2.40, 95% CI: 1.45-3.99; n = 1046/875) without significant difference in the 7-day mortality (RR = 1.12, 95% CI: 0.84-1.50; n = 951/773), symptomatic intracranial hemorrhage (RR = 1.12, 95% CI: 0.82-1.54; n = 1707/1507), or recurrent ischemic stroke (RR = 0.90, 95% CI: 0.52-1.54; n = 718/506).Conclusion:Our results demonstrated that patients in the intervention group had lower mortality and better functional outcomes than the control group. Although patients in the intervention group had a higher rate of subarachnoid hemorrhage; hence, endovascular thrombectomy combined with intravenous thrombolysis is still a beneficial intervention for a defined population of stroke patients.

AbstractObjectiveThe aim of this systematic review is to evaluate the data currently available regarding the repurposing of different drugs for Covid-19 treatment. Participants with suspected or diagnosed Covid-19 will be included. The interventions being considered are drugs being repurposed, and comparators will include standard of care treatment or placebo.MethodsWe searched Ovid-MEDLINE, EMBASE, Cochrane library, clinical trial registration site in the UK(NIHR), Europe (clinicaltrialsregister.eu), US (ClinicalTrials.gov) and internationally (isrctn.com), and reviewed the reference lists of articles for eligible articles published up to April 22, 2020. All studies in English that evaluated the efficacy of the listed drugs were included. Cochrane RoB 2.0 and ROBINS-I tool were used to assess study quality. This systematic review adheres to the PRISMA guidelines. The protocol is available at PROSPERO (CRD42020180915).ResultsFrom 708 identified studies or clinical trials, 16 studies and 16 case reports met our eligibility criteria. Of these, 6 were randomized controlled trials (763 patients), 7 cohort studies (321 patients) and 3 case series (191 patients). Chloroquine (CQ) had a 100% discharge rate compared to 50% with lopinavir-ritonavir at day 14, however a trial has recommended against a high dosage due to cardiotoxic events. Hydroxychloroquine (HCQ) has shown no significant improvement in negative seroconversion rate which is also seen in our meta-analysis (p=0.68). Adverse events with HCQ have a significant difference compared to the control group (p=0.001). Lopinavir-ritonavir has shown no improvement in time to clinical improvement which is seen in our meta-analyses (p=0.1). Remdesivir has shown no significant improvement in time to clinical improvement but this trial had insufficient power.DiscussionDue to the paucity in evidence, it is difficult to establish the efficacy of these drugs in the treatment of Covid-19 as currently there is no significant clinical effectiveness of the repurposed drugs. Further large clinical trials are required to achieve more reliable findings. A risk-benefit analysis is required on an individual basis to weigh out the potential improvement in clinical outcome and viral load reduction compared to the risks of the adverse events. (1-16)

Symptom Scores

Background Patients with moderate to severe allergic rhinitis (AR) who are treated according to the current rhinitis management guidelines may be inadequately controlled. These patients are at risk of serious comorbidities, such as asthma and chronic sinusitis. These symptoms, sneezing and an itchy, runny, stuffy nose, may have a negative impact on patients’ daily functioning. Omalizumab is being developed as a new choice for the treatment of AR. We therefore undertook a meta-analysis to assess the efficacy and safety of omalizumab in the treatment of AR. Methods We systematically searched PubMed, Cochrane Library, and MEDLINE databases for randomized controlled studies on the treatment of AR with omalizumab. Our evaluation outcomes were symptom scores, medication efficacy, combined symptom and medication scores, and adverse events. We descriptively summarized and quantitatively synthesized original data to evaluate the efficacy and safety of omalizumab in the treatment of AR by using Stata12.0 software for meta-analyses. Results The results of our meta-analysis showed that there were statistically significant differences between the omalizumab group and the control group in the following aspects: daily nasal symptom score (standardized mean difference [SMD] = –0.443, 95% confidence interval [CI]: –0.538 to –0.347, P < .001); daily ocular symptom score (SMD = –0.385, 95% CI: –0.5 to –0.269, P < .001); daily nasal medication symptom scores (SMD = –0.421, 95% CI: –0.591 to –0.251, P < .001); proportion of days of emergency drug use (risk ratio [RR] = 0.488, 95% CI: 0.307 to 0.788, P < .005); rhinoconjunctivitis-specific quality of life questionnaire (SMD = –0.286, 95% CI: –0.418 to –0.154, P < .001); and overall evaluation (RR = 1.435, 95% CI: 1.303–1.582, P < .001). There was no statistically significant difference in safety indicator: adverse events (RR = 1.026, 95% CI: 0.916–1.150, P = .655). Conclusion Omalizumab is effective and relatively safe in patients with AR; omalizumab used in conjunction with special immunotherapy has shown promising results, especially in reducing adverse events.

Objectives: An increase in life expectancy results in the aging population growth. This study was designed to evaluate the efficacy and adverse events of ginseng that could be used as a herbal medicine in women with sexual dysfunction. Materials and Methods: The authors of this study searched Cochrane Library, MEDLINE, Web of Science, Embase, Scopus, ProQuest, Google Scholar, and Persian databases without a time limitation until May 2018 and examined all the randomized clinical trials (RCTs) that compared the effect of different types of ginseng on sexual function of menopausal women as compared to the placebo controls. The Cochrane risk of bias tool was used to assess the methodological quality of the included studies. The heterogeneity was determined using the I2 index. In addition, standardized mean difference (SMD) was used instead of mean differences (MD) and a random effect was reported instead of fixed effect in meta-analysis. Results: The eligibility criteria were found in five RCTs. All the included studies were placebo-controlled. Two trials had a parallel design while three studies used a crossover design. Although four trials indicated that ginseng significantly improved sexual function, they didn’t report any treatment effect compared to the placebo group. Based on the results of meta-analysis obtained from five studies including 531 women, there was no statistically significant effect of ginseng on female sexual dysfunction (FSD) compared to the placebo control group (SMD: 0.26; 95% CI: -0.26 to 0.76). Nonetheless, there was a considerable heterogeneity among the studies (I2 = 81%; P < 0.0001). Moreover, all the included studies assessed adverse events, but in three of the RCTs, there was no significant difference between the placebo and ginseng groups. Conclusions: The evidence regarding ginseng as a therapeutic agent for sexual dysfunction is unjustifiable. Rigorous studies seem warranted in this respect.

Background. It is uncertain if omega-3 polyunsaturated fatty acids are associated with increase in resting metabolic rate (RMR) in adults. Objective. The aim of the present study was to evaluate the overall effects of omega-3 on RMR. Methods. Both PubMed and Scopus libraries were searched up to April 2021. Study quality was assessed using the Jadad scale. Random- and fixed-effects models were utilized in order to obtain pooled estimates of omega-3 supplementation impacts on RMR, using weight mean difference (WMD). Results. Seven studies including a total of 245 participants were included. There was significantly higher FFM-adjusted RMR in the intervention group than the control group (WMD: 26.666 kcal/kg/day, 95% CI: 9.010 to 44.322, p = 0.003 ). Study quality showed that four of seven included studies were of high quality. However, there was no significant difference in results in the subgroup analysis according to the quality of studies. Subgroup analyses revealed significant changes for sex (for women: WMD = 151.793 kcal/day, 95% CI = 62.249 to 241.337, p = 0.001 ) and BMI (for BMI > 25: WMD = 82.208 kcal/day, 95% CI = 0.937 to 163.480, p = 0.047 ). Influence analysis indicated no outlier among inclusions. Conclusion. The current study depicted that omega-3 polyunsaturated acids can significantly increase RMR in adults. However, further assessments of omega-3 supplementation therapy are critical to monitor its long-term outcomes and potential clinical application.

BackgroundVariability in imaging protocols and techniques has resulted in a lack of consensus regarding the incorporation of perfusion imaging into stroke triage and treatment. The objective of our study was to evaluate the available scientific evidence regarding the utility of perfusion imaging in determining treatment eligibility in patients with acute stroke and in predicting their clinical outcome.MethodsWe performed a systematic review of the literature using PubMed, Web of Science, and Cochrane Library focusing on themes of medical imaging, stroke, treatment, and outcome (CRD42016037817). We included randomized controlled trials, cohort studies, and case-controlled studies published from 2011 to 2016. Two independent reviewers conducted the study appraisal, data abstraction, and quality assessments of the studies.ResultsOur literature search yielded 13 studies that met our inclusion criteria. In total, 994 patients were treated with the aid of perfusion imaging compared with 1819 patients treated with standard care. In the intervention group 51.1% of patients had a favorable outcome at 3 months compared with 45.6% of patients in the control group (p=0.06). Subgroup analysis of studies that used multimodal therapy (IV tissue plasminogen activator, endovascular thrombectomy) showed a significant benefit of perfusion imaging (OR 1.89, 95% CI 1.43 to 2.51, p<0.01).ConclusionsPerfusion imaging may represent a complementary tool to standard radiographic assessment in enhancing patient selection for reperfusion therapy, with a subset of patients having up to 1.9 times the odds of achieving independent functional status at 3 months. This is particularly important as patients selected based on perfusion status often included individuals who did not meet the current treatment eligibility criteria.

Dichotomous Outcomes

Background: Although clonidine and dexmedetomidine are used as alpha-2 agonists to improve the quality and duration of blockade induced by local anesthetics, no study has been reported to compare their associated adverse events in local anesthesia. The aim of this study is to compare the adverse events associated with the adjuvant use of dexmedetomidine and clonidine in local anesthesia.Methods: A comprehensive search was performed to retrieve any reported adverse event associated with adjuvant use of dexmedetomidine and clonidine in local anesthesia from published literature up to 1 July 2020. Assessment of the quality of included studies was performed by the Jadad score. A comparison of any reported adverse event was made between interventions by pooling data from studies using a direct meta-analysis technique. Dichotomous outcomes were summarized as risk ratios. The review was performed according to PRISMA guideline.Results: From 121 articles retrieved from the search finally 14 articles including 1,120 patients had eligibility criteria for including in the meta-analysis. No significant difference was observed between bradycardia/hypotension (OR = 1.17; 95 % CI = 0.66–2.10; P = 0.580; I2 = 53.78 %, P = 0.027), nausea/vomiting (OR = 0.91; 95% CI = 0.59-1.42; P = 0.706; I2 = 0.0 %, P = 0.940) dizziness/headache (OR = 1.10; 95% CI = 0.44–2.75; P = 0.831; I2 = 0.0 %, P = 0.882) shivering (OR = 0.95 % CI = 0.50–1.66; P = 0.831; I2 = 0.0 %, P = 0.920) and dry mouth (OR = 1.00; 95 % CI = 0.50–1.96; P = 0.996; I2 = 0.0%, P = 0.900). No significant difference was observed in subgroup comparison of adverse events in the intravenous or local adjuvant use of the study drugs (p &gt; 0.05).Conclusion: There is no difference in adverse events associated with the intravenous or local adjuvant use of dexmedetomidine and clonidine in local anesthesia.

Introduction: Multiple myeloma, which accounts for 1% of all cancers, is a hematologic cancer in which clonal plasma-cell proliferation leads to complications and death. Over the recent years, it has shown that the introduction of novel agents, including daratumumab and the incorporation of proteasome inhibitors and immunomodulatory drugs has improved outcomes in patients with multiple myeloma. Daratumumab is a human, CD38-targeting, IgG1κ monoclonal antibody with direct antitumor effects and an immunomodulatory component and has recently shown to improve survival in patients with multiple myeloma. However, there are considerable safety concerns. The purpose of our study is to determine the risk of TD and deaths due to treatment-related adverse events (TRAE) in patients with multiple myeloma treated with daratumumab. Methods: We systematically conducted a comprehensive literature search using MEDLINE, EMBASE databases and meeting abstracts from inception through June 2019. Phase III RCTs utilizing daratumumab in patients with multiple myeloma were incorporated in the analysis. Mantel-Haenszel (MH) method was used to calculate the estimated pooled risk ratio (RR), and risk difference (RD) with 95% confidence interval (CI). Heterogeneity was assessed with Cochran's Q- statistic. Random effects model was applied. Results: Five phase III RCTs with a total of 3,547 patients with multiple myeloma were eligible. Studies compared daratumumab (D) + bortezomib (V) + melphan (M) + prednisone (P) vs VMP, D + lenalidomide (R) + dexamethasone (d) vs Rd, DVd vs Vd, DVd + thalidomide (T) vs VTd and DRd vs Rd. The randomization ratio was 1:1 in all studies. Daratumumab was utilized in relapsed and refractory multiple myeloma in the POLLUX study (n= 564) and the CASTOR study (n= 480) and as first-line treatment for patients with multiple myeloma in the ALCYONE study (n= 700), the CASSIOPEIA study (n= 1085) and the MAIA study (n= 737). The I2 statistic for heterogeneity was 39, suggesting some heterogeneity among RCTs. TD due to TRAE was noted in 120 (6.77%) vs 179 (10.08%) in control group with RR of 0.68 (95% CI: 0.51 -0.91; P = 0.0009) and RD of -0.03 (95% CI: -0.06 to 0.00; P = 0.02). TD due to infection/ pneumonia was reported in 0.95% vs 0.73% in control group (RR, 1.19; 95% CI: 0.42 -3.34; P = 0.75). Treatment-related deaths were 64 (3.61%) in daratumumab arm vs 77 (4.34%) in control arm. The pooled RR was not statistically significant at 0.86 (95% CI: 0.59 -1.25; P = 0.43). Conclusions: The rate of discontinuation of trial treatment due to adverse events was significantly lower in the daratumumab group (6.77%) than in the control arm (10.08%) with RR of 0.68, favoring daratumumab combination regimen. Furthermore, there was no significant difference in the treatment discontinuation due to pneumonia or infection and treatment-related deaths due to TRAE in the daratumumab group, compared to control arm. Disclosures No relevant conflicts of interest to declare.

Abstract Background The main purpose is to investigate the effect of LiCO3 as an add-on therapy with radioactive iodine in increasing the cure and decreasing the T4 level compared to radioactive iodine alone. The primary outcome is the cure rate as defined by the number of hyperthyroid patients who became euthyroid or hypothyroid. The secondary outcome is the T4 level. Methods Four databases were searched (PubMed, Scopus, Web of Science, and Cochrane central library). The inclusion criteria were randomized and non-randomized clinical trials of hyperthyroidism patients receiving LiCO3 with radioiodine compared with hyperthyroidism patients receiving radioactive iodine alone. Included studies were appraised with the risk of bias version 2 tool, according to the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. Results Nine studies were eligible for inclusion in the study, six randomized control trials and three non-randomized control trials. There were 477 patients in the intervention group and 451 patients in the control group. The cure rate was not significantly different between the two groups, while it was significantly increased with 5000 to 6500 mg optimized cumulative dose of LiCO3 compared with the control group, P = 0.0001. The T4 level showed no significant difference between the two groups, P = 0.13. Conclusions LiCO3 adjunct to radioactive iodine did not show significant differences compared with radioactive iodine alone in terms of cure rate or decreasing T4 level. However, the dose of 5000 to 6000 mg of LiCO3 may increase the cure rate.
