RESUMO

COVID-19 is a biphasic illness with an initial viraemia phase and later effective adaptive immune phase, except in a minority of people who develop severe disease. Immune regulation is the key target to treat COVID illness. In anticipation, an elderly man self-medicated himself with dexamethasone on the day of symptom onset of a flu-like illness, took other symptomatic measures and was tested positive for SARS-CoV-2. His condition deteriorated with each passing day resulting in hospitalisation. He demanded oxygen and declared as severe COVID. With supportive treatment, he recovered after the 20th day of illness. Immunosuppression and anti-inflammation are likely to benefit when the immune response is dysregulated and turning into a cytokine storm. A medication that has saved many could be the one predisposing to severity if taken as a preventive measure, too early in the disease course, especially the viraemia phase.

RESUMO

The current outbreak of novel COVID-19 challenges the development of an efficient treatment plan as soon as possible. Several promising treatment options stand out as potential therapy of COVID-19, including plasma-derived drugs, monoclonal antibodies, antivirals, antimalarial, cell therapy, and corticosteroids. Dexamethasone an approved corticosteroid medication, acting as an anti-inflammatory and immunosuppressant agent. In the current pandemic, dexamethasone is declared a "major development" in the fight against COVID-19. Steroidal dexamethasone was presented as the recent advancement that significantly reduces the mortality rate among severe COVID-19 cases. This review summarizes the preliminary opinion about the dexamethasone outbreak, therapeutic potential, risks, and strategies during the COVID-19 pandemic.

RESUMO

Autoimmune diseases (AUDs) are a multifactorial disease, among which rheumatoid arthritis, systemic lupus erythematosus and multiple sclerosis are more prevalent. Several anti-inflammatory, biologics, and AUD-modifying drugs are found effective against them, but their repeated use are associated with various adverse effects. In this review article, we have focused on the regulation of inflammatory molecules, molecular signaling pathways, immune cells, and epigenetics by natural product thymoquinone on AUDs. Studies indicate that thymoquinone can regulate inflammatory molecules including interferons, interleukins, tumor necrosis factor-α (TNF-α), oxidative stress, regulatory T cells, and various signaling pathways such as nuclear factor kappa beta (NF-κß), janus kinase/signal transduction and activator of transcription (JAK-STAT), mitogen-activated protein kinase (MAPK) at the molecular level and epigenetic alteration. As these molecules and signaling pathways with defective immune function play an important role in AUD development, controlling these molecules and deregulated molecular mechanism is a significant feature of AUD therapeutics. Interestingly thymoquinone is reported to possess all these potential. This article reviewed the deregulated mechanism of AUDs, and the action of thymoquinone on inflammatory molecules, immune cells, signaling pathways, and epigenetic machinery. Thymoquinone can be regarded as a potential drug candidate for AUD treatment.

RESUMO

BACKGROUND: Bronchial asthma (BA) is a chronic airway inflammatory disease with reversible airflow limitation as the main clinical manifestations, such as wheezing, cough, shortness of breath, chest tightness, etc, mediated by a variety of inflammatory cells, which can be recurrent. Clinical can improve symptoms, but cannot be cured; glucocorticoid is the most important first-line medication. Clinical practice has shown that montelukast sodium combined with fluticasone in the treatment of adult BA can improve clinical efficacy and reduce adverse reactions. The purpose of this study is to systematically study the efficacy and safety of montelukast sodium combined with fluticasone in the treatment of adult BA. METHODS: The Chinese databases (CNKI, VIP, Wanfang, Chinese Biomedical Database) and English databases (PubMed, the Cochrane Library, Embase, Web of Science) were searched by computer, for the randomized controlled clinical studies of montelukast sodium combined with fluticasone in the treatment of adult BA from establishment of database to October 2020. Two researchers independently extracted the relevant data and evaluated the quality of the literatures, and used RevMan5.3 software to conduct meta-analyze of the included literatures. RESULTS: This study assessed the efficacy and safety of montelukast sodium combined with fluticasone in the treatment of adult BA through total effective rate, pulmonary function (FEV1, FVC, PEF, FEV1/FVC), and adverse reactions. CONCLUSION: This study will provide reliable evidence-based evidence for the clinical application of montelukast sodium combined with fluticasone in the treatment of adult BA.

RESUMO

BACKGROUND: Although corticosteroid prophylaxis in adult cardiac surgery has been studied extensively for 40 years, its role remains controversial, and the optimal dose remains uncertain. The objective of this meta-analysis was to estimate the clinical benefits and risks of corticosteroid use in cardiopulmonary bypass. METHODS: We will search Pubmed, Web of Science, Embase, Clinical Trials, and Cochrane Central Register of Controlled Trials for relevant clinical trials published in any language before August 1, 2020. Randomized controlled trials (RCTs) of interest which meet inclusion criteria published or unpublished will be included. We will divide the included studies into child and adult groups for analysis. If sufficient data are available, the included trials will be divided into 4 subgroups: ≤20 mg/kg (low dose), 20-40 mg/kg (slightly high dose), 40-100 mg/kg (high dose), and >100 mg/kg (ultra high dose) based on the equivalent hydrocortisone dose. INPLASY registration number: INPLASY2020100044. RESULTS: The results of this study will be published in a peer-reviewed journal. CONCLUSION: This study will compare the efficacy of tprophylactic corticosteroids for adults and children undergoing cardiac surgery with CPB. Due to the nature of the disease and intervention methods, randomized controlled trials may be inadequate, and we will carefully consider inclusion in high-quality, non-randomized controlled trials, but this may result in high heterogeneity and affect the reliability of the results.

RESUMO

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBD) patients management has been challenging during the ongoing coronavirus disease 2019 (COVID-19) pandemic, due to lockdowns, limitation of access to medical facilities and new recommendations regarding patient management. The implications of the COVID-19 pandemic on IBD patients' management were assessed in our Tertiary Gastroenterology Center in Bucharest, Romania. METHODS: Medical records of IBD patients admitted between 15th of March and 15th of August 2020 were retrospectively reviewed and compared to a control cohort of consecutive IBD patients admitted to our unit during the corresponding period of 2019. RESULTS: There was a highly significant shift towards one-day hospitalization during the referral period in 2020 for IBD cases (91% in 2020 vs 82.2% in 2019, p=0.0001). There was no statistically significant difference between the distribution of patient's gender, IBD phenotype or newly diagnosed IBD cases. A significantly lower proportion of admitted patients received 5-aminosalicylic acid (29% vs 41.2%, p=0.0001), whereas a substantially higher number of patients were prescribed biological therapy in 2020 in comparison to the corresponding 2019-time frame (79.5% vs 57.9%, p<0.0001). The distribution of the biological agent used was significantly different in 2019 in comparison to the 2020 period mainly due to the increase in vedolizumab prescription in 2020 (p<0.0001). During the study period in 2020, seven IBD patients (1.7%) were diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) infection, all of them with mild symptoms without impact on the IBD course. CONCLUSIONS: The COVID-19 pandemic led to reorganizing medical care, limiting the hospital admissions in favor of severe IBD cases, favoring telemedicine for mild disease and optimization of treatment for moderate to severe IBD with an increased use of biologicals aimed to maximize the risk/benefit ratio. Incidence of SARS-Cov2 infection during the first wave of COVID-19 infection in our study group was 1.7% and did not adversely impact the IBD disease course.

RESUMO

BACKGROUND: Numerous clinical trials and observational studies have investigated various pharmacological agents as potential treatment for Coronavirus Disease 2019 (COVID-19), but the results are heterogeneous and sometimes even contradictory to one another, making it difficult for clinicians to determine which treatments are truly effective. METHODS AND FINDINGS: We carried out a systematic review and network meta-analysis (NMA) to systematically evaluate the comparative efficacy and safety of pharmacological interventions and the level of evidence behind each treatment regimen in different clinical settings. Both published and unpublished randomized controlled trials (RCTs) and confounding-adjusted observational studies which met our predefined eligibility criteria were collected. We included studies investigating the effect of pharmacological management of patients hospitalized for COVID-19 management. Mild patients who do not require hospitalization or have self-limiting disease courses were not eligible for our NMA. A total of 110 studies (40 RCTs and 70 observational studies) were included. PubMed, Google Scholar, MEDLINE, the Cochrane Library, medRxiv, SSRN, WHO International Clinical Trials Registry Platform, and ClinicalTrials.gov were searched from the beginning of 2020 to August 24, 2020. Studies from Asia (41 countries, 37.2%), Europe (28 countries, 25.4%), North America (24 countries, 21.8%), South America (5 countries, 4.5%), and Middle East (6 countries, 5.4%), and additional 6 multinational studies (5.4%) were included in our analyses. The outcomes of interest were mortality, progression to severe disease (severe pneumonia, admission to intensive care unit (ICU), and/or mechanical ventilation), viral clearance rate, QT prolongation, fatal cardiac complications, and noncardiac serious adverse events. Based on RCTs, the risk of progression to severe course and mortality was significantly reduced with corticosteroids (odds ratio (OR) 0.23, 95% confidence interval (CI) 0.06 to 0.86, p = 0.032, and OR 0.78, 95% CI 0.66 to 0.91, p = 0.002, respectively) and remdesivir (OR 0.29, 95% CI 0.17 to 0.50, p < 0.001, and OR 0.62, 95% CI 0.39 to 0.98, p = 0.041, respectively) compared to standard care for moderate to severe COVID-19 patients in non-ICU; corticosteroids were also shown to reduce mortality rate (OR 0.54, 95% CI 0.40 to 0.73, p < 0.001) for critically ill patients in ICU. In analyses including observational studies, interferon-alpha (OR 0.05, 95% CI 0.01 to 0.39, p = 0.004), itolizumab (OR 0.10, 95% CI 0.01 to 0.92, p = 0.042), sofosbuvir plus daclatasvir (OR 0.26, 95% CI 0.07 to 0.88, p = 0.030), anakinra (OR 0.30, 95% CI 0.11 to 0.82, p = 0.019), tocilizumab (OR 0.43, 95% CI 0.30 to 0.60, p < 0.001), and convalescent plasma (OR 0.48, 95% CI 0.24 to 0.96, p = 0.038) were associated with reduced mortality rate in non-ICU setting, while high-dose intravenous immunoglobulin (IVIG) (OR 0.13, 95% CI 0.03 to 0.49, p = 0.003), ivermectin (OR 0.15, 95% CI 0.04 to 0.57, p = 0.005), and tocilizumab (OR 0.62, 95% CI 0.42 to 0.90, p = 0.012) were associated with reduced mortality rate in critically ill patients. Convalescent plasma was the only treatment option that was associated with improved viral clearance rate at 2 weeks compared to standard care (OR 11.39, 95% CI 3.91 to 33.18, p < 0.001). The combination of hydroxychloroquine and azithromycin was shown to be associated with increased QT prolongation incidence (OR 2.01, 95% CI 1.26 to 3.20, p = 0.003) and fatal cardiac complications in cardiac-impaired populations (OR 2.23, 95% CI 1.24 to 4.00, p = 0.007). No drug was significantly associated with increased noncardiac serious adverse events compared to standard care. The quality of evidence of collective outcomes were estimated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. The major limitation of the present study is the overall low level of evidence that reduces the certainty of recommendations. Besides, the risk of bias (RoB) measured by RoB2 and ROBINS-I framework for individual studies was generally low to moderate. The outcomes deducted from observational studies could not infer causality and can only imply associations. The study protocol is publicly available on PROSPERO (CRD42020186527). CONCLUSIONS: In this NMA, we found that anti-inflammatory agents (corticosteroids, tocilizumab, anakinra, and IVIG), convalescent plasma, and remdesivir were associated with improved outcomes of hospitalized COVID-19 patients. Hydroxychloroquine did not provide clinical benefits while posing cardiac safety risks when combined with azithromycin, especially in the vulnerable population. Only 29% of current evidence on pharmacological management of COVID-19 is supported by moderate or high certainty and can be translated to practice and policy; the remaining 71% are of low or very low certainty and warrant further studies to establish firm conclusions.

RESUMO

BACKGROUND: Patients with severe, uncontrolled asthma, particularly those with a non-eosinophilic phenotype, have a great unmet need for new treatments that act on a broad range of inflammatory pathways in the airway. Tezepelumab is a human monoclonal antibody that blocks the activity of thymic stromal lymphopoietin, an epithelial cytokine. In the PATHWAY phase 2b study (NCT02054130), tezepelumab reduced exacerbations by up to 71% in adults with severe, uncontrolled asthma, irrespective of baseline eosinophilic inflammatory status. This article reports the design and objectives of the phase 2 CASCADE study. METHODS: CASCADE is an ongoing exploratory, phase 2, randomized, double-blind, placebo-controlled, parallel-group study aiming to assess the anti-inflammatory effects of tezepelumab 210 mg administered subcutaneously every 4 weeks for 28 weeks in adults aged 18-75 years with uncontrolled, moderate-to-severe asthma. The primary endpoint is the change from baseline to week 28 in airway submucosal inflammatory cells (eosinophils, neutrophils, T cells and mast cells) from bronchoscopic biopsies. Epithelial molecular phenotyping, comprising the three-gene-mean technique, will be used to assess participants' type 2 (T2) status to enable evaluation of the anti-inflammatory effect of tezepelumab across the continuum of T2 activation. Other exploratory analyses include assessments of the impact of tezepelumab on airway remodelling, including reticular basement membrane thickening and airway epithelial integrity. At the onset of the COVID-19 pandemic, the protocol was amended to address the possibility that site visits would be limited. The amendment allowed for: at-home dosing of study drug by a healthcare professional, extension of the treatment period by up to 6 months so patients are able to attend an onsite visit to undergo the end-of-treatment bronchoscopy, and replacement of final follow-up visits with a virtual or telephone visit. DISCUSSION: CASCADE aims to determine the mechanisms by which tezepelumab improves clinical asthma outcomes by evaluating the effect of tezepelumab on airway inflammatory cells and remodelling in patients with moderate-to-severe, uncontrolled asthma. An important aspect of this study is the evaluation of the anti-inflammatory effect of tezepelumab across patients with differing levels of eosinophilic and T2 inflammation. TRIAL REGISTRATION: NCT03688074 (ClinicalTrials.gov). Registered 28 September 2018.

RESUMO

Patients with coronavirus disease 2019 (COVID-19) frequently experience a coagulopathy associated with a high incidence of thrombotic events leading to poor outcomes. Here, biomarkers of coagulation (such as D-dimer, fibrinogen, platelet count), inflammation (such as interleukin-6), and immunity (such as lymphocyte count) as well as clinical scoring systems (such as sequential organ failure assessment [SOFA], International Society on Thrombosis and Hemostasis disseminated intravascular coagulation [ISTH DIC], and sepsis-induced coagulopathy [SIC] score) can be helpful in predicting clinical course, need for hospital resources (such as intensive care unit [ICU] beds, intubation and ventilator therapy, and extracorporeal membrane oxygenation [ECMO]) and patient's outcome in patients with COVID-19. However, therapeutic options are actually limited to unspecific supportive therapy. Whether viscoelastic testing can provide additional value in predicting clinical course, need for hospital resources and patient's outcome or in guiding anticoagulation in COVID-19-associated coagulopathy is still incompletely understood and currently under investigation (eg, in the rotational thromboelastometry analysis and standard coagulation tests in hospitalized patients with COVID-19 [ROHOCO] study). This article summarizes what we know already about COVID-19-associated coagulopathy and-perhaps even more importantly-characterizes important knowledge gaps.

RESUMO

Recurrent pericarditis (RP) occurs in 15% to 30% of patients following a first episode, despite standard treatment with nonsteroidal anti-inflammatory drugs, colchicine, and corticosteroids; many patients become dependent on corticosteroids. Rilonacept (KPL-914), an interleukin-1α and ß inhibitor, is in development for the treatment of RP. RHAPSODY, a double-blind, placebo-controlled, randomized-withdrawal (RW) pivotal Phase 3 trial (NCT03737110), enrolls patients 12 years or older presenting with at least a third pericarditis episode, pericarditis pain score ≥4 (11-point numeric rating scale [NRS]), and C-reactive protein ≥1 mg/dL at screening. After a subcutaneous loading dose (adults, 320 mg; children, 4.4 mg/kg), all patients receive blinded weekly subcutaneous rilonacept (adults, 160 mg; children, 2.2 mg/kg) during the run-in period. Patients must taper and discontinue concomitant pericarditis medications during the blinded run-in period and achieve clinical response (C-reactive protein ≤0.5 mg/dL and weekly average NRS ≤2.0 during the 7 days prior to and including the day of randomization) by end of the run-in (while on rilonacept monotherapy) to be randomized to either continued rilonacept or placebo in the RW period. Primary efficacy end point was time to adjudicated pericarditis recurrence during the RW period; secondary efficacy end points were proportion of patients maintaining clinical response, percentage of days with NRS ≤2, and percentage of patients with no-to-minimal pericarditis symptoms at week 16 of the RW period. Safety evaluations include adverse event monitoring, physical examinations, and laboratory tests. The RHAPSODY trial will evaluate the efficacy and safety of rilonacept in the treatment of RP to improve outcomes and patient health-related quality of life.

RESUMO

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-COV2) infection is a recently emerged viral infection causing predominantly mild upper respiratory symptoms. However, in some instances, it might result in acute respiratory distress syndrome (ARDS) that poses a significant mortality risk. ARDS is postulated to be mediated by a surge of pro-inflammatory cytokines and chemokines, leading to a dysregulated hyper inflammatory response. Colchicine being an anti-inflammatory agent, might mitigate this dysregulated response. Thus, in the absence of therapeutic options available to manage coronavirus disease 2019 (COVID-19), it is imperative to ascertain the effect of colchicine on improving outcomes in COVID-19 patients. METHOD: We will perform a systematic review including a search of the following databases: PubMed, EMBASE, MEDLINE, Clinicaltrials.gov, Cochrane library, and google scholar since inception. We will include randomized controlled trials exploring the effect of colchicine on the efficacy and safety outcomes of COVID-19 patients. Subsequently, we will perform a meta-analysis utilizing the random-effects to ascertain the effect of colchicine on reducing COVID-19 related mortality (primary endpoint) and other efficacy and safety outcomes. RESULTS: Our review results are anticipated in early 2021 (based on the completion of several ongoing randomized controlled trial). Our review results will be published in a peer-reviewed journal. CONCLUSION: This systematic review and meta-analysis, is exploring the effect of colchicine on the efficacy and safety outcomes of COVID-19 patients. If colchicine proved to be effective, it would be a significant milestone in the management of COVID-19, a disease with limited available therapeutic options.

RESUMO

OBJECTIVES: In some patients, acute, life-threatening respiratory injury produced by viruses such as SARS-CoV and other viral pneumonia are associated with an over-exuberant cytokine release. Elevated levels of blood IL-6 had been identified as a one of the risk factors associated with severe COVID-19 disease. Anti-IL6 inhibitors are among the therapeutic armamentarium for preventing the fatal consequences of acute respiratory and multi organ failure in around 20% of the COVID-19 infected patients. At present, their use is prioritized to patients with severe interstitial pneumonia (Brescia-COVID Scale-COVID 2-3) with hyperinflammation as determined by the presence of elevated IL6 and/or d-dimer, or progressive d-dimer increase, in patients who otherwise are subsidiary to ICU admission. However, many uncertainties remain on the actual role of anti-IL6 inhibitors in this setting, and whether current use and timing is the right one. There is the hypothesis that the use of anti-IL6 inhibitors at an earlier state during the hyperinflammatory syndrome would be beneficial and may avoid progressing to ARDS. On the other hand, the standard of care has changed and nowadays the use of corticosteroids has become part of the SOC in the treatment of COVID-19 pneumonia. Our limited experience suggests that better treatment outcomes can be achieved when combining IL6-inhibitors (e.g. sarilumab) with corticosteroids. The aim of the present study is to evaluate if an earlier therapeutic intervention with sarilumab plus SOC (including corticosteroids) may be more effective than current standard of care alone, in preventing progression to respiratory failure in COVID-19 infected patients with interstitial pneumonia. This study will also provide supportive evidence to that provided by currently ongoing studies on the efficacy and safety of sarilumab in this clinical context. TRIAL DESIGN: A phase two multi-center randomised controlled trial (RCT) with two parallel arms (1:1 ratio). PARTICIPANTS: They will be hospitalized patients, of at least 18 years of age, with severe COVID-19 who have positive RT-PCR test and have radiographic evidence of pulmonary infiltrates by imaging or rales/crackles on exam and SpO2 ≤ 94% on room air that requires supplemental oxygen. Patients must present elevation of inflammatory parameters (IL-6 > 40 pg/mL or d-dimer >1.0 mcg/ml) or, alternatively, progressive worsening in at least two of these inflammatory parameters in the prior 24-48h: CRP, LDH, serum ferritin, lymphopenia, or d-dimer. EXCLUSION CRITERIA: high oxygen requirements (including face mask with reservoir, non-invasive mechanical ventilation or high flow nasal cannula, or mechanical ventilation), admission to ICU, pregnancy or lactation, allergy or hypersensitivity to sarilumab or corticoesteroids, immunosuppressive antibody therapy within the past 5 months, AST/ALT values > 10 x ULN, neutropenia (< 0.5 x 109/L), severe thrombocytopenia (< 50 x 109/L), sepsis caused by an alternative pathogen, diverticulitis with risk of perforation or ongoing infectious dermatitis. The study will be conducted in several hospitals in Spain. INTERVENTION AND COMPARATOR: Patients randomised to the experimental arm will receive sarilumab + methylprednisolone plus SOC for COVID-19. Patients included in the control arm will receive methylprednisolone plus SOC for COVID-19. Corticosteroids will be given to all patients at a 1mg/kg/d of methylprednisolone for at least 3 days. Clinical follow-up visits will be performed at 3, 5, and 15 days after treatment randomization. Patients in the control group (SOC group without sarilumab) progressing to Brescia- COVID 2-3 plus inflammatory markers, will be given the option to be rescued with sarilumab at the same doses and, in that case, be included in an open-label phase and be followed up for additional weeks (with visits at 3, 7 and 15 days after sarilumab rescue administration). Patients randomly assigned to sarilumab therapy at baseline progressing to Brescia-COVID 2-3 will be rescued according to local clinical practice protocols. A final follow-up visit will be conducted for all patients at day 29 from randomization, regardless of initial treatment assignment. MAIN OUTCOMES: Primary end point is the proportion of patients progressing to either severe respiratory failure (Brescia-COVID ≥2), ICU admission, or death. RANDOMIZATION: Randomization codes were produced by means of the PROC PLAN of the SAS system, with a 1:1 assignment ratio, stratifying by centre and using blocks multiple of 2 elements. The randomization schedule will be managed through the eCRF in a concealed manner. BLINDING (MASKING): All study drugs will be administered as open label. No blinding methods will be used in this trial. NUMBERS TO BE RANDOMISED (SIMPLE SIZE): The target sample size will be 200 COVID-19 patients, who will be allocated randomly to control arm (100) and treatment arm (100). TRIAL STATUS: Protocol Code: SARTRE Protocol Date: May 05th 2020. Version: 2.0 The study has been approved by the Spanish Competent Authority (AEMPS) as a low intervention clinical trial. Start of recruitment: August, 2020 End of recruitment: May, 2021 TRIAL REGISTRATION: Identifier: EudraCT Number: 2020-002037-15 ; Registration date: 26 May 2020.

RESUMO

BACKGROUND: Multiple randomized controlled trials (RCTs) and systematic reviews have been conducted to summarize the evidence for administration of local anesthetic (lidocaine) alone or with steroids, with discordant opinions, more in favor of equal effect with local anesthetic alone or with steroids. OBJECTIVE: To evaluate the comparative effectiveness of lidocaine alone and lidocaine with steroids in managing spinal pain to assess superiority or equivalency. STUDY DESIGN: A systematic review of RCTs assessing the effectiveness of lidocaine alone compared with addition of steroids to lidocaine in managing spinal pain secondary to multiple causes (disc herniation, radiculitis, discogenic pain, spinal stenosis, and post-surgery syndrome). METHODS: This systematic review was performed utilizing Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) for literature search, Cochrane review criteria, and Interventional Pain Management Techniques-Quality Appraisal of Reliability and Risk of Bias Assessment (IPM-QRB) to assess the methodologic quality assessment and qualitative analysis utilizing best evidence synthesis principles, and quantitative analysis utilizing conventional and single-arm meta-analysis. PubMed, Cochrane Library, US National Guideline Clearinghouse, Google Scholar, and prior systematic reviews and reference lists were utilized in the literature search from 1966 through December 2019. The evidence was summarized utilizing principles of best evidence synthesis on a scale of 1 to 5. OUTCOME MEASURES: A hard endpoint for the primary outcome was defined as the proportion of patients with 50% pain relief and improvement in function. Secondary outcome measures, or soft endpoints, were pain relief and/or improvement in function. Effectiveness was determined as short-term if it was less than 6 months. Improvement that lasted longer than 6 months, was defined as long-term. RESULTS: Based on search criteria, 15 manuscripts were identified and considered for inclusion for qualitative analysis, quantitative analysis with conventional meta-analysis, and single-arm meta-analysis. The results showed Level II, moderate evidence, for short-term and long-term improvement in pain and function with the application of epidural injections with local anesthetic with or without steroid in managing spinal pain of multiple origins. LIMITATIONS: Despite 15 RCTs, evidence may still be considered as less than optimal and further studies are recommended. CONCLUSION: Overall, the present meta-analysis shows moderate (Level II) evidence for epidural injections with lidocaine with or without steroids in managing spinal pain secondary to disc herniation, spinal stenosis, discogenic pain, and post-surgery syndrome based on relevant, high-quality RCTs. Results were similar for lidocaine, with or without steroids.

RESUMO

BACKGROUND: The suppression of hypothalamic-pituitary-adrenal (HPA) axis is a common complication associated with epidural steroid injections (ESIs). However, the effect of different doses is unknown. OBJECTIVES: The primary objective was to compare the differences in the duration of HPA suppression following treatment with different doses of ESI; triamcinolone acetate (TA) 40 mg and TA 20 mg. The secondary objectives were to compare the extent of salivary cortisol (SC) reduction, the incidence of adrenal insufficiency (AI), and the differences in a numeric rating scale (NRS) depending on the varying levels of TA dose used for ESI. STUDY DESIGN: A double-blind, parallel-group, randomized controlled trial. SETTING: Pain clinics in a university hospital. METHODS: The patients were treated with TA epidurally and divided into 2 groups (T20 and T40) depending on the dose of TA (20 mg and 40 mg). The SC concentration was measured before and after ESI to calculate the duration of HPA axis suppression, the extent of SC concentration reduction, and the SC recovery rate. Additionally, NRS and adrenocorticotropic hormone stimulation tests were used. RESULTS: Thirty patients were analyzed. The T40 group showed longer HPA suppression (19.7 ± 3.1 days) compared with that of the T20 group (8.0 ± 2.4 days). The recovery rate of the T40 group was lower than that of the T20 group (P < 0.015). However, there was no difference in the extent of reduction in SC concentration after ESI, the occurrence of AI, and pain reduction. LIMITATIONS: There were selection bias and no placebo control. CONCLUSIONS: Although the difference in pain relief according to the ESI dose is not significant, the HPA suppression is prolonged with a higher dose than a lower dose, and the recovery is slower. Therefore, the time interval between consecutive ESIs should be adjusted depending on the steroid dose to ameliorate the adverse effects of steroids.

RESUMO

OBJECTIVES: Tocilizumab is a humanized monoclonal antibody which targets and inhibits interleukin-6 (IL-6) and has demonstrated efficacy in treating diseases associated with hyper-inflammation. Data are suggestive of tocilizumab as a potential treatment for patients with COVID-19 infection. The aim of this study is to determine the safety and efficacy of standard dose versus low dose tocilizumab in adults with severe, non-critical, PCR-confirmed COVID-19 infection with evidence of progressive decline in respiratory function and evolving systemic inflammation on time to intubation, non-invasive ventilation and/or all-cause mortality. TRIAL DESIGN: This trial is a phase 2, open label, two-stage, multicentre, randomised trial. PARTICIPANTS: Adult subjects with severe, non-critical, PCR-confirmed COVID-19 infection with evidence of progressive decline in respiratory function and evolving systemic inflammation requiring admission to hospital at St. Vincent's University Hospital and Mater Misericordiae University Hospital, Dublin, Ireland. Inclusion criteria Aged 18 years or older. Confirmed SARS-CoV2 infection (as defined by positive PCR). Evidence of hyper inflammatory state as evidenced by at least three of the following: Documented temperature >38°C in the past 48 hours, IL6 >40 pg/ml, or in its absence D-dimer >1.5 µgFEU /ml, Elevated CRP (>100mg/L) and/or a three-fold increase since presentation, Elevated ferritin X5 ULN, Elevated LDH (above the ULN), Elevated fibrinogen (above the ULN). Pulmonary infiltrates on chest imaging. Moderate to severe respiratory failure as defined by PaO2/FiO2≤300mmHg. INTERVENTION AND COMPARATOR: Intervention for participants in this trial is SOC plus Tocilizumab compared to SOC alone (comparator). For Stage 1, following randomisation, subjects will receive either (Arm 1) SOC alone or (Arm 2) SOC plus Tocilizumab (standard single dose - 8mg/kg, infused over 60 minutes. Once stage 1 has fully recruited, subsequent participants will be enrolled directly into Stage 2 and receive either (Arm 1) SOC plus Tocilizumab (standard single dose - 8mg/kg, infused over 60 minutes or (Arm 2) SOC plus Tocilizumab (standard single dose - 4mg/kg, infused over 60 minutes). MAIN OUTCOMES: The primary endpoint for this study is the time to a composite primary endpoint of progression to intubation and ventilation, non-invasive ventilation or death within 28 days post randomisation. RANDOMISATION: Eligible patients will be randomised (1:1) using a central register. Randomisation will be performed through an interactive, web-based electronic data capturing database. In stage 1, eligible participants will be randomised (1:1) to (Arm 1) SOC alone or to (Arm 2) SOC with single dose (8mg/kg, maximum 800mg) intravenous tocilizumab infused over 60 minutes. In stage 2, eligible participants will be randomised (1:1) to receive either (Arm 1) single, standard dose (8mg/kg, maximum 800mg) intravenous tocilizumab infused over 60 minutes or (Arm 2) reduced dose (4mg/kg, maximum 800mg) intravenous tocilizumab infused over 60 minutes. BLINDING: This study is open label. The study will not be blinded to investigators, subjects, or medical or nursing staff. The trial statistician will be blinded for data analysis and will be kept unaware of treatment group assignments. To facilitate this, the randomisation schedule will be drawn up by an independent statistician and objective criteria were defined for the primary outcome to minimize potential bias. NUMBERS TO BE RANDOMISED: In stage 1, 90 subjects will be randomised 1:1, 45 to SOC and 45 subjects to SOC plus Tocilizumab (8mg/kg, infused over 60 minutes). In stage 2, sample size calculation for the dose evaluation stage will use data generated from stage 1 using the same primary endpoint as in stage 1. TRIAL STATUS: The COVIRL002 trial (Protocol version 1.4, 13th May 2020) commenced in May 2020 at St. Vincent's University Hospital and Mater Misericordiae University Hospital, Dublin, Ireland. Recruitment is proceeding with the aim to achieve the target sample size on or before April 2021. TRIAL REGISTRATION: COVIRL002 was registered 25 June 2020 under EudraCT number: 2020-001767-86 and Protocol identification: UCDCRC/20/02. FULL PROTOCOL: The full protocol for COVIRL002 is attached as an additional file, accessible from the Trials website (Additional file 1).

RESUMO

OBJECTIVES: The main aim of the study is to evaluate the efficacy of a single dose of sarilumab, in subcutaneous administration, in hospitalised patients with moderate to early severe COVID-19 infection compared to the current standard of care, to prevent progression to systemic hyperinflammatory status. Our hypothesis is that use of subcutaneous sarilumab in early stages (window of opportunity) of COVID-19 moderate-severe pneumonia can prevent higher oxygenation requirements through non-invasive and invasive mechanical ventilation and decrease in-hospital stays, as well as death rate. The secondary objectives of the study are to evaluate the safety of sarilumab through hospitalisation and up to day 14 after discharge, compared to the control arm as assessed by incidence of serious and non serious adverse events (SAEs). In addition, as an exploratory objective, to compare the baseline clinical and biological parameters, including serum IL-6 levels, of the intervention population against controls of the same pandemic outbreak (using a propensity score) to search for markers that identify the best candidates for the treatment with subcutaneous IL-6R inhibitors and to attempt an approximation in the temporal frame of the "window of opportunity" TRIAL DESIGN: SARCOVID is an investigator-initiated single center randomised proof of concept study. PARTICIPANTS: Patients treated at the Hospital Universitario La Princesa, Madrid, Spain requiring hospitalisation will be consecutively recruited, meeting all inclusion criteria and none of the exclusion criteria Inclusion criteria a.

RESUMO

AIM: To describe the first Australian cases of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV2) disease (COVID-19) pneumonia treated with the interleukin-6 receptor antagonist tocilizumab. METHODS: Retrospective, open-label, real-world, uncontrolled, single-arm case series conducted in 2 tertiary hospitals in NSW, Australia and 1 tertiary hospital in Victoria, Australia. Five adult male patients aged between 46 and 74 years with type 1 respiratory failure due to COVID-19 pneumonia requiring intensive care unit (ICU) admission and biochemical evidence of systemic hyperinflammation (C-reactive protein greater than 100 mg/L; ferritin greater than 700 µg/L) were administered variable-dose tocilizumab. RESULTS: At between 13 and 26 days follow-up, all patients are alive and have been discharged from ICU. Two patients have been discharged home. Two patients avoided endotracheal intubation. Oxygen therapy has been ceased in three patients. Four adverse events potentially associated with tocilizumab therapy occurred in three patients: ventilator-associated pneumonia, bacteremia associated with central venous catheterization, myositis and hepatitis. All patients received broad-spectrum antibiotics, 4 received corticosteroids and 2 received both lopinavir/ritonavir and hydroxychloroquine. The time from first tocilizumab administration to improvement in ventilation, defined as a 25% reduction in fraction of inspired oxygen required to maintain peripheral oxygen saturation greater than 92%, ranged from 7 hours to 4.6 days. CONCLUSIONS: Tocilizumab use was associated with favorable clinical outcome in our patients. We recommend tocilizumab be included in randomized controlled trials of treatment for patients with severe COVID-19 pneumonia, and be considered for compassionate use in such patients pending the results of these trials.

RESUMO

The Strategic Plan for Biodefense Research by the U.S. Department of Health and Human Services demarcates the need for drugs which target multiple types of pathogens to prepare for infectious threats. Azithromycin is one such broad-spectrum therapeutic that is both included in the University of Oxford's RECOVERY and excluded from the World Health Organization's SOLIDARITY trials. Here we review azithromycin's broad antibiotic, antimalarial, antiviral pharmacology and contextualise it against a broader history as the most repositioned therapeutic of the macrolide class; we further evaluate azithromycin's clinical and socio-economic propriety for respiratory pandemics and delineate a model for its combinatorial mechanism of action against COVID-19 pneumonia.
