Introduction: Although convalescent plasma (CP) treatment is a potential therapeutic option for patients with COVID-19, there is a paucity of data from intensive care unit (ICU) patients with COVID-19 in low-resource settings, such as Suriname. CP was produced by a novel gravity-based filtration method. Methods: In an open-label, multi-center, non-randomized prospective clinical trial, patients with severe or life- threatening COVID-19 symptoms (n=28) with CP treatment were compared with standard treatment alone (n=50). A pre-planned interim analysis is reported. The primary endpoint was a 28-day ICU mortality. Secondary endpoints were changes two days after treatment initiation in pulmonary oxygen exchange capacity (PF ratio) and chest x-ray (CXR) score. Results: Mortality occurred in 18% (CP: 5/28) vs. 36% (Control:18/50). CP treatment of severe COVID-19 resulted in a higher probability of survival, with a hazard ratio (HR) of 0.22 (95% CI, 0.074-0.067), correcting for age, the presence of diabetes and COVID-19 severity. In the severe group, CP resulted in an improved CXR score (P = 0.0013) and increase in PF ratio (P = 0.011) as compared to standard therapy. The gravity-based plasmapheresis method used for CP production was well-tolerated and no adverse events were observed in the donors. Discussion: CP therapy in combination with standard treatment resulted in 78% reduction of 28-day ICU mortality (HR = 0.22) compared to standard treatment alone. Both CXR-score and PF ratio changes represent effective indicators for the treatment effect of CP after two days. The novel CP production method was effective and represents a practical solution for Low- and middle-income countries to produce CP.

Background Although convalescent plasma (CP) treatment is a potential therapeutic option for patients with COVID-19, there is a paucity of data from studies in low-resource settings. The efficacy and safety of CP therapy in intensive care unit (ICU) patients with COVID-19 in Suriname was evaluated. A novel gravity-based filtration method was used to obtain CP. The design was an open-label, multi-centre, non-randomized prospective clinical trial performed in two hospitals in Suriname, from June 2020, to December 2020. A pre-planned interim analysis is reported in 78 PCR-confirmed COVID-19 patients admitted to the ICU with severe or lifethreatening symptoms. CP in combination with standard treatment (n = 28) was compared to standard treatment alone (control) (n = 50), stratified by disease severity. The primary endpoint was 28-day ICU mortality. Secondary (exploratory) endpoints were changes two days after treatment initiation in pulmonary oxygen exchange capacity (PF ratio) and chest xray (CXR) score. Findings The median age of patients was 52 years with 43 [55.1%] being male. Twenty-eight day mortality occurred in 18% (5/28) of the CP group vs 36% (18/50) of the control group. Survival probability was significantly higher in the CP group compared to the control group with standard care (P=0.027). When stratifying into disease severity, the survival probability was the lowest for the control group with life-threatening disease (P=0.0051). CP treatment of severe COVID-19 resulted in a higher probability of survival, with a hazard ratio (HR) of 0.22 (95% CI, 0.074-0.067), correcting for age, the presence of diabetes and COVID-19 severity. Age significantly increased the mortality risk (HR, 1.08 [95%CI, 1.022-1.14]; P =0.006). In the severe group, CP resulted in an improved CXR score (P =0.0013) and increase in PF ratio (P = 0.011) as compared to standard therapy. The gravity-based plasmapheresis method used for CP production was well-tolerated and no adverse events were observed in the donors. Interpretation Among patients with severe or life-threatening COVID-19, CP therapy in combination with standard treatment resulted in 78% reduction of 28-day ICU mortality (HR = 0.22) compared to standard treatment alone. Both CXR-score and PF ratio changes represent indicators of treatment effect of CP after two days and can easily be implemented in low-resource settings. The novel CP production method was effective and represents a practical solution for low and middle income countries (LMICs) to produce CP locally. Although interpretation is limited by the non-randomised design of the trial, these results offer a potential route for broader implementation of CP treatment in LMICs.

Background Definitive antiviral treatment is not available for COVID-19 infection except remdesivir that even with many doubts. Various combination antivirals have been tried. Methods A single-center, open-label, parallel-arm, stratified randomized controlled trial evaluated the therapeutic potential of hydroxychloroquine and lopinavir-ritonavir in combination with ribavirin in COVID-19. Enrolled patients in severe category were randomized into three groups: A: standard treatment, B: hydroxychloroquine+ribavirin+standard treatment, or C: lopinavir+ritonavir+ribavirin+standard treatment; while non-severe category into two groups: A: standard treatment or B: hydroxychloroquine+ribavirin. Combination antivirals was given for 10 days and followed for 28 days. The primary endpoints were safety, symptomatic and laboratory recovery of organ dysfunctions, and time to SARS-CoV-2 RT-PCR negative report. Results Total 111 patients randomized: 24, 23, and 24 in severe category A, B, and C respectively, and 20 in each non-severe group. Two patients receiving ribavirin experienced drug induced liver injury and another developed QT prolongation after hydroxychloroquine. In the severe category, 47.6%, 55%, and 30.09% in A, B, and C groups respectively showed symptomatic recovery compared to 93.3% and 86.7% in A and B groups respectively in the non-severe category at 72hrs (P>0.05). Conclusions The results failed to show statistical superiority of the antiviral combination therapies to that of the standard therapy in both the severe and non-severe categories in symptomatic adult patients of COVID-19. However, results do indicate the benefit of non-standard interventional combination therapy in severe disease. Furthermore, the dose of ribavirin needs to be reconsidered in the Indian population.

Background: It is unknown if improvements in ischemic stroke (IS) outcomes reported after cerebral reperfusion therapies (CRT) in developed countries are also applicable to the “real world” scenario of low and middle-income countries. We aimed to measure the long-term outcomes of severe IS treated or not with CRT in Brazil. Methods: Patients from a stroke center of a state-run hospital were included. We compared the survival probability and functional status at 3 and 12 months in patients with severe IS treated or not with CRT. From 2010 to 2011, we performed intravenous reperfusion when patients arrived within 4.5 h time-window (IVT group) and after 2011, mechanical thrombectomy (MT) combined or not with intravenous alteplase (IAT group). Those who arrived >4.5 h in 2010-2011 and >6 h in 2012-2017 did not undergo CRT (NCRT group). Results: From 2010 to 2017, we registered 917 patients: 74% (677/917) in the NCRT group, 19% (178/917) in the IVT group and 7% (62/917) in the IAT group. Compared to the NCRT group, IVT patients had a 28% higher (HR: 0.72; 95% CI 0.53-0.96) 3-month adjusted probability of survival and risk of functional dependence was 19% lower (adjusted RR: 0.81; 95% CI 0.73-0.91). For those who underwent MT, the adjusted probability of survival was 59 % higher (HR: 0.41; 95% CI 0.21-0.77) and the risk of functional dependence was 21% lower (adjusted RR: 0.79; 95% CI 0.66-094). These outcomes remained significantly better throughout the first year. Conclusion: CRT led to better outcomes in patients with severe IS in Brazil.

Abstract Background ABO-incompatible liver transplantation (ABO-i LT) has become a rescue therapeutic option for patients with severe hepatic failure. Although the use of rituximab greatly reduces the morbidity of antibody-mediated rejection (AMR), severe adverse effects, such as infection and biliary complications, still seriously threaten the survival of transplant recipients. The aim of this study was to evaluate the safety and feasibility of using mesenchymal stem cells (MSCs) to replace rituximab in ABO-i LT. Methods Twenty-two patients with severe hepatic failure undergoing ABO-i LT were enrolled and randomly divided into two groups: the MSC group and the rituximab group. The safety of the application of MSCs and the incidence of allograft rejection, including antibody-mediated rejection (AMR) and acute cellular rejection (ACR), were evaluated in both groups at the 2-year follow-up period as primary endpoints. Recipients and graft survival and other postoperative complications were compared as secondary endpoints. Results No severe MSC-related adverse events were observed during the trial. MSC treatment yielded comparable, if not better, results than rituximab at decreasing the incidence of acute rejection (9.1% vs 27.3%). Inspiringly, compared to those in the rituximab group, the rates of biliary complications (0% vs 45.5%) and infection (9.1% vs 81.8%) were significantly decreased in the MSC group. In addition, there were no significant differences in 2-year graft and recipient survival between the two groups (81.8% vs 72.7%). Conclusions Our data show that MSC transfusion is comparable to rituximab treatment for AMR prophylaxis following ABO-i LT. Additionally, the results indicate that MSCs are more beneficial to the prevention of infection and biliary complications and may be introduced as a novel immunosuppressive approach for ABO-i LT.

Abstract Background We aimed to assess the safety and efficacy of combination treatment with panitumumab plus trifluridine/tipiracil (FTD/TPI) in patients with wild-type RAS metastatic colorectal cancer (mCRC) who were refractory/intolerant to standard therapies other than anti-epidermal growth factor receptor therapy. Methods APOLLON was an open-label, multicentre, phase 1/2 trial. In the phase 1 part, 3 + 3 de-escalation design was used to investigate the recommended phase 2 dose (RP2D); all patients in the phase 2 part received the RP2D. The primary endpoint was investigator-assessed progression-free survival (PFS) rate at 6 months. Secondary endpoints included PFS, overall survival (OS), overall response rate (ORR), disease control rate (DCR), time to treatment failure (TTF), and safety. Results Fifty-six patients were enrolled (phase 1, n = 7; phase 2, n = 49) at 25 Japanese centres. No dose-limiting toxicities were observed in patients receiving panitumumab (6 mg/kg every 2 weeks) plus FTD/TPI (35 mg/m2 twice daily; days 1–5 and 8–12 in a 28-day cycle), which became RP2D. PFS rate at 6 months was 33.3% (90% confidence interval [CI] 22.8–45.3). Median PFS, OS, ORR, DCR, and TTF were 5.8 months (95% CI 4.5–6.5), 14.1 months (95% CI 12.2–19.3), 37.0% (95% CI 24.3–51.3), 81.5% (95% CI 68.6–90.8), and 5.8 months (95% CI 4.29–6.21), respectively. Neutrophil count decreased (47.3%) was the most common Grade 3/4 treatment-emergent adverse event. No treatment-related deaths occurred. Conclusion Panitumumab plus FTD/TPI exhibited favourable anti-tumour activity with a manageable safety profile and may be a therapeutic option for pre-treated mCRC patients.

Introduction: Shwasa is said as Shigrapranahara Roga. It occurs as the main disease and also a symptom in various diseases. Shwasakruchrata is a common symptom that occurs in Hrudroga. Acharya Charaka mentioned the unique classification of drugs based on their action. Shwasahara Dashemani is one among them. It is containing 10 herbal drugs which are specially indicated in Shwasa Roga. Hence to evaluate the efficacy of Shwasahara Dashemani in Lakshana Roopi Shwasa in L.V.F (Cardiac Asthma) has taken for the study. Aim and Objective: The objective is to assess the efficacy of Shwasahara Dashemani in L.V.F with dyspnea (Cardiac Asthma). Method: The present study is a controlled comparative, open-label, clinical trial with pre and post-test design. A total of 40 subjects of a diagnosed case of L.V.F with dyspnea (Cardiac Asthma) were selected by using a simple random sampling method. Control group subjects were intervened with standard treatment of L.V.F and intervention group subjects were intervened with standard treatment of L.V.F along with Shwasahara Dashemani Ghana Vati, for the duration of 30 days. Its efficacy was assessed before treatment (0th day) and after treatment (31st day) by using BDI (Baseline Dyspnea Index Scale). Results: The P-value of dyspnea of the control group is 1.000 and the P-value of dyspnea of the intervention group is 0.105. This shows that the results of both groups are statistically not significant. But as compared to the control group, the intervention group is clinically significant because after the intervention 35% of subjects had shown improvement in the intervention group. Conclusion: As compared to the control group, in the intervention group Shwasahara Dashemani Ghanavati is clinically significant in relieving cardiac asthma when used with standard treatment of L.V.F.

Abstract Background Strategic drug therapy for rheumatoid arthritis (RA) patients with prolonged remission is not well defined. According to recent guidelines, tapering biological Disease Modifying Anti-Rheumatic Drugs (bDMARDs) may be considered. We aimed to evaluate the long-term maintenance of tocilizumab (TCZ) treatment after the progressive tapering of infusions. Methods We conducted an exploratory, prospective, single-center, open label study, on RA patients with sustained remission for at least 3 months and treated with TCZ infusions every 4 weeks. The initial re-treatment interval was 6 weeks for the first 3 months. Thereafter, the spacing between infusions was determined by the clinician. Successful long-term maintenance following the tapering of TCZ infusions was defined by patients still treated after two years by TCZ with a minimum dosing interval of 5 weeks. Results Thirteen patients were enrolled in the study. Eight out of thirteen were still treated by TCZ after two years. Successful long-term maintenance was possible in six patients, with four patients maintaining a re-treatment interval of 8-weeks or more. We observed 5 patients with TCZ withdrawal: one for adverse drug reaction (neutropenia) and four with secondary failure. Patients achieving successful long-term maintenance with TCZ were significantly younger than those with secondary failure (p<0.05). In addition, RA patients with positive rheumatoid factor and anti-citrullinated peptide antibodies, experienced a significantly greater number of flares during our 2-year follow-up (p<0.01). Conclusions A progressive tapering of TCZ infusions seems possible in most of the patients. However, larger studies, including more patients, are needed to confirm this therapeutic option.

Graves’ orbitopathy (GO) is the most common extrathyroidal manifestation of Graves’ disease (GD). Our aim was to assess the efficacy and safety of Tocilizumab (TCZ) in GO refractory to conventional therapy. This was an open-label multicenter study of glucocorticoid-resistant GO treated with TCZ. The main outcomes were the best-corrected visual acuity (BVCA), Clinical Activity Score (CAS) and intraocular pressure (IOP). These outcome variables were assessed at baseline, 1st, 3rd, 6th and 12th month after TCZ therapy onset. The severity of GO was assessed according to the European Group on Graves’ Orbitopathy (EUGOGO). We studied 48 (38 women and 10 men) patients (95 eyes); mean age ± standard deviation 51 ± 11.8 years. Before TCZ and besides oral glucocorticoids, they had received IV methylprednisolone (n = 43), or selenium (n = 11). GO disease was moderate (n =29) or severe (n = 19) and dysthyroid optic neuropathy (DON) (n = 7). TCZ was used in monotherapy (n = 45) or combined (n = 3) at a dose of 8 mg/kg IV every four weeks (n = 43) or 162 mg/s.c. every week (n = 5). TCZ yielded a significant improvement in all of the main outcomes at the 1st month that was maintained at one year. Comparing the baseline with data at 1 year all of the variables improved; BCVA (0.78 ± 0.25 vs. 0.9 ± 0.16; p = 0.0001), CAS (4.64 ± 1.5 vs. 1.05 ± 1.27; p = 0.0001) and intraocular pressure (IOP) (19.05 ± 4.1 vs. 16.73 ± 3.4 mmHg; p = 0.007). After a mean follow-up of 16.1 ± 2.1 months, low disease activity (CAS ≤ 3), was achieved in 88 eyes (92.6%) and TCZ was withdrawn in 29 cases due to low disease activity (n = 25) or inefficacy (n = 4). No serious adverse events were observed. In conclusion, TCZ is a useful and safe therapeutic option in refractory GO treatment.
