Pharmacological treatment in adult patients with CRPS-I: A systematic review and meta-analysis of randomised controlled trials
Rheumatology (Oxford, England). 2022
OBJECTIVE Several pharmacological treatments have been proposed for the treatment of Complex regional pain syndrome type-I (CRPS-I) in adults, but data regarding the efficacy of various agents for this disease is scarce. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to analyse pharmacological approaches in adults with CRPS-I. METHODS We systematically searched PubMed, Scopus, and Web of Science databases from the inception date to 30, June 2021 for identifying placebo-controlled or active-controlled RCTs using bisphosphonates, ketamine, corticosteroids, anti-epileptics, NSAIDs/COXIBs, opiates, antidepressants, scavengers/magnesium sulphate or intravenous immunoglobulins for the treatment of CRPS-I. The primary outcomes included changes in the visual analogue scale (VAS) or numeric rating scale (NRS) for pain before and after treatment. RESULTS We included 20 placebo-controlled or active-controlled RCTs (for a total of 818 CRPS-I adults) that used bisphosphonates (n = 7), ketamine (n = 2), corticosteroids (n = 2), anti-epileptics (n = 1), NSAIDs/COXIBs (n = 2), scavengers/magnesium (n = 5), or intravenous immunoglobulins (n = 1) to treat CRPS-I during a median follow-up of 26 weeks. The treatment with bisphosphonates showed a significant reduction of the values of the VAS/NRS pain scale compared with placebo or reference therapy (random effects weighted mean difference [WMD]: -23.8, 95%CI-28.0 to -19.6; I2=36.4%). Treatment with ketamine also documented a reduction in the values of the VAS/NRS pain scale (random effects WMD: -8.27,95%CI -12.9 to -3.70; I2=0%). Treatment with other agents did not improve the values of the VAS/NRS pain scale. CONCLUSION This systematic review and meta-analysis supports the recommendation of parenteral bisphosphonates as the first-line agent in the treatment of CRPS-I.

Multisystemic Inflammatory Syndrome in Neonates: A Systematic Review
INTRODUCTION Multisystem inflammatory syndrome in neonates (MIS-N) related to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has increasingly been reported worldwide amid the spread of the SARS-CoV-2 pandemic. METHODS We searched PubMed, EMBASE, and CINAHL and preprint servers (BioRxiv.org and MedRxiv.org) using a specified strategy integrating Medical Subject Headings terms and keywords until October 20, 2021. Our aim was to systematically review demographic profiles, clinical features, laboratory parameters, complications, treatments, and outcomes of neonates with MIS-N. Studies were selected when fulfilling the inclusion criteria. Articles were included if they fulfilled the World Health Organization (WHO), Centers for Disease Control (CDC) definitions of MIS-C, or our proposed definition. RESULTS Sixteen reports of MIS-N including 47 neonates meeting MIS-N criteria were identified. Presentation included cardiovascular compromise (77%), respiratory involvement (55%), and fever in (36%). Eighty-three percent of patients received steroids, and 76% received immunoglobulin. Respiratory support was provided to 60% of patients and inotropes to 45% of patients. Five (11%) neonates died. CONCLUSION The common presentation of MIS-N included cardiorespiratory compromise with the possibility of high mortality. Neonates with MIS-N related to SARS-CoV-2 may be at higher risk of adverse outcomes.
Potentially effective drugs for the treatment of COVID-19 or MIS-C in children: a systematic review
European journal of pediatrics. 2022;:1-12
The purpose of this systematic review is to evaluate the efficacy and safety of using potential drugs: remdesivir and glucocorticoid in treating children and adolescents with COVID-19 and intravenous immunoglobulin (IVIG) in treating MIS-C. We searched seven databases, three preprint platform, ClinicalTrials.gov, and Google from December 1, 2019, to August 5, 2021, to collect evidence of remdesivir, glucocorticoid, and IVIG which were used in children and adolescents with COVID-19 or MIS-C. A total of nine cohort studies and one case series study were included in this systematic review. In terms of remdesivir, the meta-analysis of single-arm cohort studies have shown that after the treatment, 54.7% (95%CI, 10.3 to 99.1%) experienced adverse events, 5.6% (95%CI, 1.2 to 10.1%) died, and 27.0% (95%CI, 0 to 73.0%) needed extracorporeal membrane oxygenation or invasive mechanical ventilation. As for glucocorticoids, the results of the meta-analysis showed that the fixed-effect summary odds ratio for the association with mortality was 2.79 (95%CI, 0.13 to 60.87), and the mechanical ventilation rate was 3.12 (95%CI, 0.80 to 12.08) for glucocorticoids compared with the control group. In terms of IVIG, most of the included cohort studies showed that for MIS-C patients with more severe clinical symptoms, IVIG combined with methylprednisolone could achieve better clinical efficacy than IVIG alone.Conclusions: Overall, the current evidence in the included studies is insignificant and of low quality. It is recommended to conduct high-quality randomized controlled trials of remdesivir, glucocorticoids, and IVIG in children and adolescents with COVID-19 or MIS-C to provide substantial evidence for the development of guidelines. What is Known: • The efficacy and safety of using potential drugs such as remdesivir, glucocorticoid, and intravenous immunoglobulin (IVIG) in treating children and adolescents with COVID-19/MIS-C are unclear. What is New: • Overall, the current evidence cannot adequately demonstrate the effectiveness and safety of using remdesivir, glucocorticoids, and IVIG in treating children and adolescents with COVID-19 or MIS-C. • We are calling for the publication of high-quality clinical trials and provide substantial evidence for the development of guidelines.
The emerging threat of multisystem inflammatory syndrome in adults (MIS-A) in COVID-19: A systematic review
Heart & lung : the journal of critical care. 2022;54:7-18
BACKGROUND The exact prevalence of Multisystem Inflammatory Syndrome in Adults (MIS-A) is largely unknown. Vague and multiple definitions and treatment options often add to the confusion on how to label the diagnosis with certainty. OBJECTIVES The objective of the study was to determine the demographic profile, clinical presentation, laboratory findings and outcomes of MIS-A in COVID-19. METHODS A systematic review was conducted after registering with PROSPERO. Multiple databases were systematically searched to encompass studies characterizing MIS-A from 1st January 2020 up to 31st August 2021. The inclusion criteria were- to incorporate all published or in press peer-reviewed articles reporting cases of MIS-A. We accepted the following types of studies: case reports, case-control, case series, cross-sectional studies and letters to the editors that incorporated clinical, laboratory, imaging, as well as the hospital course of MIS-A patients. The exclusion criteria for the review were- articles not in English, only abstracts published, no data on MIS-A and articles which have focus on COVID-19, and not MIS-A. Two independent authors screened the articles, extracted the data, and assessed the risk of bias. RESULTS A total of 53 articles were included in this review with a sample size of 79 cases. Majority of the patients were males (73.4%) with mean age of 31.67±10.02 years. Fever (100%) and skin rash (57.8%) were the two most common presenting symptoms. Echocardiographic data was available for 73 patients of whom 41 (73.2%) had reduced left ventricular ejection fraction. Cardiovascular system was most frequently involved (81%) followed by gastrointestinal (73.4%) and mucocutaneous (51.9%) involvement. Anti-inflammatory therapies used in treatment included steroids (60.2%), intravenous immunoglobulin (37.2%) and biologics (10.2%). Mean duration of the hospital stay was 11.67±8.08 days. Data regarding the outcomes was available for all 79 subjects of whom 4 (5.1%) died during course of hospital stay. CONCLUSIONS Emergence of MIS-A calls for further large-scale studies to establish standard case definitions and definite treatment guidelines.
Multisystem Inflammatory Syndrome Temporally Related to COVID-19 in Children From Latin America and the Caribbean Region: A Systematic Review With a Meta-Analysis of Data From Regional Surveillance Systems
Frontiers in pediatrics. 2022;10:881765
BACKGROUND With the emergence of the COVID-19 pandemic, increasing numbers of cases of the multisystem inflammatory syndrome in children (MIS-C) have been reported worldwide; however, it is unclear whether this syndrome has a differential pattern in children from Latin America and the Caribbean (LAC). We conducted a systematic review and meta-analysis to analyze the epidemiological, clinical, and outcome characteristics of patients with MIS-C in LAC countries. METHODS A systematic literature search was conducted in the main electronic databases and scientific meetings from March 1, 2020, to June 30, 2021. Available reports on epidemiological surveillance of countries in the region during the same period were analyzed. RESULTS Of the 464 relevant studies identified, 23 were included with 592 patients with MIS-C from LAC. Mean age was 6.6 years (IQR, 6-7.4 years); 60% were male. The most common clinical manifestations were fever, rash, and conjunctival injection; 59% showed Kawasaki disease. Pool proportion of shock was 52%. A total of 47% of patients were admitted to the pediatric intensive care unit (PICU), 23% required mechanical ventilation, and 74% required vasoactive drugs. Intravenous gamma globulin alone was administered in 87% of patients, and in combination with steroids in 60% of cases. Length of hospital stay was 10 days (IQR, 9-10) and PICU stay 5.75 (IQR, 5-6). Overall case fatality ratio was 4% and for those hospitalized in the PICU it was 7%. CONCLUSION Limited information was available on the clinical outcomes. Improvements in the surveillance system are required to obtain a better epidemiologic overview in the region.
COVID-19 associated vasculitis: A systematic review of case reports and case series
Annals of medicine and surgery (2012). 2022;:103249
Vasculitis is one of the complications of COVID-19. We conducted a systematic review analysing the association of COVID-19 with vasculitis. We searched Google Scholar and PubMed from December 1, 2019, to October 11, 2021. The review included 8 studies (7 case reports and 1 case series) reporting 9 cases of vasculitis secondary to COVID-19. The mean age was 29.17 ± 28.2 years, ranging from 6 months to 83 years. The male to female ratio was 4:5. Maculopapular, violaceous, papular and erythematous rash were common. Heparin(n = 2), corticosteroids (n = 6) (methylprednisolone) and intravenous immunoglobulin (n = 4) were prescribed in these patients. Significant clinical improvement was observed in 8 out of 9 patients. One person died during treatment. Our study discusses vasculitis as one of the complications of COVID-19. Furthermore, the pathophysiology, clinical presentation, and management of COVID-19 associated vasculitis is discussed.
Etanercept with IVIg for acute Kawasaki disease: a long-term follow-up on the EATAK trial
Cardiology in the young. 2022;:1-6
BACKGROUND The Etanercept as Adjunctive Treatment for Acute Kawasaki Disease, a phase-3 clinical trial, showed that etanercept reduced the prevalence of IVIg resistance in acute Kawasaki disease. In patients who presented with coronary artery involvement, it reduced the maximal size and short-term progression of coronary artery dilation. Following up with this patient group, we evaluated the potential long-term benefit of etanercept for coronary disease. METHODS Patients were followed for at least 1 year after the trial. The size of dilated arteries (z-score ≥ 2.5) was measured at each follow-up visit. The z-score and size change from baseline were evaluated at each visit and compared between patients who received etanercept versus placebo at the initial trial. RESULTS Forty patients who received etanercept (22) or placebo (18) in the Etanercept as Adjunctive Treatment for Acute Kawasaki Disease trial were included. All patients showed a persistent decrease in coronary artery size measurement: 23.3 versus 5.9% at the 6-month visit, 24 versus 13.1% at the 1-year visit, and 20.8 versus 19.3% at the ≥ 2-year visit for etanercept or placebo, respectively, with similar results for decrease in coronary artery z-scores. In a multivariate analysis, correcting for patients' growth, a greater size reduction for patients on the etanercept arm versus placebo was proved significant for the 6-month (p = 0.005) and the 1-year visits (p = 0.019) with a similar end outcome at the ≥ 2-year visit. DISCUSSION Primary adjunctive therapy with etanercept for children with acute Kawasaki disease does not change the end outcome of coronary artery disease but may promote earlier resolution of artery dilation.
Randomized trial of three IVIg doses for treating chronic inflammatory demyelinating polyneuropathy
Brain : a journal of neurology. 2022
Intravenous immunoglobulin treatment for chronic inflammatory demyelinating polyneuropathy usually starts with a 2.0 g/kg induction dose followed by 1.0 g/kg maintenance doses every 3 weeks. No dose-ranging studies with intravenous immunoglobulin maintenance therapy have been published. The Progress in Chronic Inflammatory Demyelinating polyneuropathy (ProCID) study was a prospective, double-blind, randomised, parallel-group, multicentre, phase III study investigating the efficacy and safety of 10% liquid intravenous immunoglobulin (panzyga®) in patients with active chronic inflammatory demyelinating polyneuropathy. Patients were randomised 1:2:1 to receive the standard intravenous immunoglobulin induction dose and then either 0.5, 1.0 or 2.0 g/kg maintenance doses every 3 weeks. The primary endpoint was the response rate in the 1.0 g/kg group, defined as an improvement ≥ 1 point in adjusted Inflammatory Neuropathy Cause and Treatment score at Week 6 versus baseline and maintained at Week 24. Secondary endpoints included dose response and safety. This trial was registered with EudraCT (Number 2015-005443-14) and clinicaltrials.gov (NCT02638207). Between August 2017 and September 2019, the study enrolled 142 patients. All 142 were included in the safety analyses. As no post infusion data were available for three patients, 139 were included in the efficacy analyses, of whom 121 were previously on corticosteroids. The response rate was 80% (55/69 patients) (95% confidence interval: 69-88%) in the 1.0 g/kg group, 65% (22/34; confidence interval: 48-79%) in the 0.5 g/kg group, and 92% (33/36; confidence interval 78-97%) in the 2.0 g/kg group. While the proportion of responders was higher with higher maintenance doses, logistic regression analysis showed that the effect on response rate was driven by a significant difference between the 0.5 and 2.0 g/kg groups, whereas the response rates in the 0.5 and 2.0 g/kg groups did not differ significantly from the 1.0 g/kg group. Fifty-six percent of all patients had an adjusted Inflammatory Neuropathy Cause and Treatment score improvement 3 weeks after the induction dose alone. Treatment-related adverse events were reported in 16 (45.7%), 32 (46.4%) and 20 (52.6%) patients in the 0.5, 1.0 and 2.0 g/kg dose groups, respectively. The most common adverse reaction was headache. There were no treatment-related deaths. Intravenous immunoglobulin 1.0 g/kg was efficacious and well tolerated as maintenance treatment for patients with chronic inflammatory demyelinating polyneuropathy. Further studies of different maintenance doses of intravenous immunoglobulin in chronic inflammatory demyelinating polyneuropathy are warranted.
Furosemide and albumin for the treatment of nephrotic edema: a systematic review
Pediatric nephrology (Berlin, Germany). 2022
BACKGROUND Edema is one of the cardinal clinical features of nephrotic syndrome (NS). It may vary from mild periorbital edema to severe generalized edema (anasarca). In patients where edema does not improve with prednisone therapy, the most common supportive medications are diuretics and albumin. However, due to the complex pathophysiology of edema formation in NS patients resulting in intravascular normovolemia or hypovolemia, optimal therapy for edema is still debated. We conducted a systematic review with the objective of evaluating the change in urine volume and urine sodium excretion after treatment with furosemide only versus furosemide with albumin in edematous patients with NS. OBJECTIVES (1) To evaluate efficacy of furosemide alone versus furosemide with albumin in the treatment of nephrotic edema in adults and children. (2) To compare the harms and benefits of different doses of furosemide for treating nephrotic edema. SEARCH METHODS The search included all randomized or quasi-randomized controlled trials in English and French using MEDLINE, Embase, and CENTRAL Trials Registry of the Cochrane Collaboration using the Ovid interface. ClinicalTrials.gov and the International Clinical Trials Registry Platform were also searched. SELECTION CRITERIA We included all RCTs and randomized cross-over studies in which furosemide and furosemide plus albumin are used in the treatment of children or adults with nephrotic edema. We excluded patients with hypoalbuminemia of non-renal origin and severe chronic kidney disease (CKD) with a glomerular filtration rate below 30 ml/min/1.74 m(2) and patients with congenital NS. DATA COLLECTION AND ANALYSIS All abstracts were independently assessed by at least two authors to determine which studies met the inclusion criteria. Information on study design, methodology, and outcome data (urine volume, urine sodium excretion, adverse effects) from each identified study was entered into a separate data sheet. The differences in outcomes between the types of therapy were expressed as standardized mean difference (SMD) with 95% confidence intervals (CI). RESULTS The search yielded 525 records, and after screening, five studies were included in the systematic review and four of those studies in the meta-analysis. One study had high risk of bias and the remaining three studies were deemed to have some concerns. Urine excretion was greater after treatment with furosemide and albumin versus furosemide (SMD 0.85, 95% CI = 0.33 to 1.38). Results for sodium excretion were inconclusive (SMD 0.37, 95%CI = - 0.28 to 1.02). AUTHORS' CONCLUSIONS The current evidence is not sufficient to make definitive conclusions about the role of albumin in treating nephrotic edema. High-quality randomized studies with adequate samples sizes are needed. Including an assessment of intravascular volume status may be helpful.

Post COVID-19 pulmonary fibrosis; a meta-analysis study
Annals of medicine and surgery (2012). 2022;77:103590
Introduction; Pulmonary fibrosis is a frequently reported COVID-19 sequela in which the exact prevalence and risk factors are yet to be established. This meta-analysis aims to investigate the prevalence of post-COVID-19 pulmonary fibrosis (PCPF) and the potential risk factors. Methods; CINAHL, PubMed/MEDLINE, Cochrane Library, Web of Science, and EMBASE databases were searched to identify English language studies published up to December 3, 2021. Results; The systematic search initially revealed a total of 618 articles - of which only 13 studies reporting 2018 patients were included in this study. Among the patients, 1047 (51.9%) were male and 971 (48.1%) were female. The mean age was 54.5 years (15-94). The prevalence of PCPF was 44.9%. The mean age was 59 years in fibrotic patients and 48.5 years in non-fibrotic patients. Chronic obstructive pulmonary disease was the only comorbidity associated with PCPF. Fibrotic patients more commonly suffered from persistent symptoms of dyspnea, cough, chest pain, fatigue, and myalgia (p-value < 0.05). Factors related to COVID-19 severity that were associated with PCPF development included computed tomography score of ≥18, ICU admission, invasive/non-invasive mechanical ventilation, longer hospitalization period, and steroid, antibiotic and immunoglobulin treatments (p-value < 0.05). Parenchymal bands (284/341), ground-glass opacities (552/753), interlobular septal thickening (220/381), and consolidation (197/319) were the most common lung abnormalities found in fibrotic patients. Conclusion, About 44.9% of COVID-19 survivors appear to have developed pulmonary fibrosis. Factors related to COVID-19 severity were significantly associated with PCPF development.
