The World Health Organization (WHO) recommends intravenous (IV) ampicillin and gentamicin as first-line therapy to treat severe pneumonia in children under five years of age. Ampicillin needs to be administered at a six-hourly interval, which requires frequent nursing intervention and bed occupancy for 5–7 days, limiting its utility in resource-poor settings. We compared the efficacy of IV amoxicillin over IV ampicillin, which is a potential alternative drug in treating severe pneumonia in children between 2–59 months. We conducted an unblinded, randomized, controlled, non-inferiority trial in the Dhaka hospital of icddr,b from 1 January 2018 to 31 October 2019. Children from 2–59 months of age presenting with WHO defined severe pneumonia with respiratory danger signs were randomly assigned 1:1 to either 50 mg/kg ampicillin or 40 mg/kg amoxicillin per day with 7.5 mg/kg gentamicin. The primary outcome was treatment failure as per the standard definition of persistence of danger sign(s) of severe pneumonia beyond 48 h or deterioration within 24 h of therapy initiation. The secondary outcomes were: (i) time required for resolution of danger signs since enrolment, (ii) length of hospital stay, (iii) death during hospitalization, and (iv) rate of nosocomial infections. Among 308 enrolled participants, baseline characteristics were similar among the two groups. Sixty-two (20%) children ended up with treatment failure, 21 (14%) in amoxicillin, and 41 (27%) in ampicillin arm, which is statistically significant (relative risk [RR] 0.51, 95% CI 0.32–0.82; p = 0.004). We reported 14 deaths for serious adverse events, 4 (3%) and 10 (6%) among amoxicillin and ampicillin arm, respectively. IV amoxicillin and IV gentamicin combination is not inferior to combined IV ampicillin and IV gentamicin in treating severe pneumonia in under-five children in Bangladesh. Considering the less frequent dosing and more compliance, IV amoxicillin is a better choice for treating children with severe pneumonia in resource-limited settings.

Daily Dose

Background Pneumonia causes about 0.9 million deaths worldwide each year. The World Health Organization (WHO) guidelines for the standard management of severe pneumonia requires parenteral ampicillin every 6 hours and once-daily parenteral gentamicin for 5 to 7 days. Although this treatment has contributed to the reduction of mortality, it requires nursing interventions every 6 hours for 7 days. Further intervention trials should be conducted to search for alternate antibiotics with better adherence, reduced cost, and reduced hospital stay. Parenteral amoxicillin is an effective alternative to ampicillin, as it has a longer half-life and broader coverage. Objective The aim of this clinical trial is to compare the efficacy of a dose of injectable amoxicillin every 12 hours plus a once-daily dose of injectable gentamicin with a dose of injectable ampicillin every 6 hours plus a once-daily dose of injectable gentamicin in children hospitalized for severe pneumonia. Methods This randomized, controlled, open-label, noninferiority trial is being conducted in Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh. A sample size of 308 children with severe pneumonia will give adequate power to this study. Children aged 2 to 59 months are randomized to either intravenous ampicillin or intravenous amoxicillin, plus intravenous gentamicin in both study arms. The monitoring of the patients is carried out according to the WHO protocol for the treatment of severe pneumonia. The primary objective is the rate of treatment failure, defined by the persistence of danger signs of severe pneumonia beyond 48 hours or deterioration within 24 hours of initiation of the therapy. The secondary objectives are (1) improvement in or the resolution of danger signs since enrollment, (2) length of hospital stay, (3) death during hospitalization, and (4) rate of nosocomial infections. Results Enrollment in the study started on January 1, 2018, and ended on October 31, 2019. Data entry and analysis are in progress. Findings from the study are expected to be disseminated in October 2020. Conclusions Our study's findings will improve compliance with the use of antibiotics that require less frequent doses for the treatment of severe pneumonia.

ObjectivesTo determine the long-term safety and efficacy of allopurinol dose escalation (DE) to achieve target serum urate (SU) in gout.MethodsPeople, including those with chronic kidney disease, who completed the first 12 months of a randomised controlled trial continued into a 12-month extension study. Participants randomised to continue current dose for the first 12 months began allopurinol DE at month 12 if SU was ≥6 mg/dL (control/DE). Immediate DE participants who achieved target SU maintained allopurinol dose (DE/DE). The primary endpoints were reduction in SU and adverse events (AEs) at month 24.ResultsThe mean (SE) change in SU from month 12 to 24 was −1.1 (0.2) mg/dL in control/DE and 0.1 (0.2) mg/dL in DE/DE group (p<0.001). There was a significant reduction in the percentage of individuals having a gout flare in the month prior to months 12 and 24 compared with baseline in both groups and in mean tophus size over 24 months, but no difference between randomised groups. There were similar numbers of AEs and serious adverse events between groups.ConclusionsThe majority of people with gout tolerate higher than creatinine clearance-based allopurinol dose and achieve and maintain target SU. Slow allopurinol DE may be appropriate in clinical practice even in those with kidney impairment.Trial registration numberACTRN12611000845932

Abstract ​ Background: Antimalarial resistance is a threat to recent gains in malaria control. This study aimed to assess the efficacy and safety of artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) in the management of uncomplicated malaria and to measure the prevalence of molecular markers of resistance of Plasmodium falciparum in sentinel sites in Maferinyah and Labé Health Districts in Guinea in 2016. Methods: This was a two-arm randomized controlled trial of the efficacy of AL and ASAQ among children aged 6-59 months with uncomplicated P. falciparum malaria in two sites. Children were followed for 28 days to assess clinical and parasitological response. The primary outcome was the Kaplan-Meier estimate of Day 28 (D28) efficacy after correction by microsatellite-genotyping. Pre-treatment (D0) and day of failure samples were assayed for molecular markers of resistance in the pfk13 and pfmdr1 genes. Results: A total of 421 participants were included with 211 participants in the Maferinyah site and 210 in Labé. No early treatment failure was observed in any study arms. However, 22 (5.3%) participants developed a late treatment failure (8 in the ASAQ arm and 14 in the AL arm), which were further classified as 2 recrudescences and 20 reinfections. The Kaplan-Meier estimate of the corrected efficacy at D28 was 100% for both AL and ASAQ in Maferinyah site and 99% (95% Confidence Interval: 97.2-100%) for ASAQ and 99% (97.1-100%) for AL in Labé. The majority of successfully analyzed D0 (98%, 380/389) and all day of failure (100%, 22/22) samples were wild type for pfk13 . All 9 observed pfk13 mutations were polymorphisms not associated with artemisinin resistance. The NFD haplotype was the predominant haplotype in both D0 (197/362, 54%) and day of failure samples (11/18, 61%) successfully analyzed for pfmdr1 . Vomiting was the most common observed side effect (14%) across all arms. Conclusions: This study observed high efficacy and safety of both ASAQ and AL in Guinea, providing evidence for their continued use to treat uncomplicated malaria. Continued monitoring of ACT efficacy and safety and molecular makers of resistance in Guinea is important to detect emergence of parasite resistance and to inform evidence-based malaria treatment policies.

ABSTRACT New antibiotics are required to have the antibacterial activity against doxycycline-resistant Orientia tsutsugamushi. An in vitro sensitivity study showed that telithromycin was more effective than erythromycin for Rickettsia, Bartonella, and Coxiella burnetii. In this prospective, open-label, randomized trial, we enrolled patients with mild-to-moderate scrub typhus. We compared the efficacy and safety of a 5-day telithromycin therapy with those of a 5-day doxycycline therapy at Chosun University Hospital or one of its two community-based affiliated hospitals (Jangheung Hospital and Cheomdan Hospital), which are all located in southwestern Korea, between September and December 2005. A total of 92 patients were randomly assigned to either the telithromycin group (n = 47) or the doxycycline group (n = 45). After the treatment, fever control time was 20.45 ± 12.9 h in the telithromycin group and 22.60 ± 21.44 h in the doxycycline group (P > 0.05). After the treatment, the cure rate was 100% in the telithromycin group and 97.8% in the doxycycline group (P > 0.05). Furthermore, there were no significant differences in time elapsed until such symptoms as headache, myalgia, and rash disappeared. No serious adverse events or death were noted following the treatment in both groups. There were no significant differences in adverse events. In conclusion, the efficacy and safety of a 5-day once-a-day regimen of 800 mg telithromycin were equivalent to those of a 5-day twice-a-day regimen of 100 mg doxycycline in patients with mild-to-moderate scrub typhus. Telithromycin could be considered a promising new antibacterial agent for patients with scrub typhus.

The efficacy of convalescent plasma for COVID-19 is unclear. While most randomized controlled trials have shown negative results, uncontrolled studies have suggested that the antibody content may influence patient outcomes. We conducted an open-label, randomized controlled trial of convalescent plasma for adults with COVID-19 receiving oxygen within 12 days of respiratory symptom onset. Patients were allocated 2:1 to 500 mL of convalescent plasma or standard of care. The composite primary outcome was intubation or death by 30 days. The effect of convalescent plasma antibodies on the primary outcome was assessed by logistic regression. The trial was terminated at 78% of planned enrollment after meeting stopping criteria for futility. 940 patients were randomized and 921 patients were included in the intent-to-treat analysis. Intubation or death occurred in 199/614 (32.4%) in the convalescent plasma arm and 86/307 (28.0%) in the standard of care arm; relative risk (RR) 1.16 (95% confidence interval (CI) 0.94-1.43; p=0.18). Patients in the convalescent plasma arm had more serious adverse events (33.4% vs. 26.4%; RR=1.27, 95% CI 1.02-1.57, p=0.034). The antibody content significantly modulated the therapeutic effect of convalescent plasma. In multivariate analysis, each standard log increase in neutralization or antibody-dependent cellular cytotoxicity independently reduced the potential harmful effect of plasma (OR=0.74; 0.57-0.95 and OR=0.66; 0.50-0.87, respectively), while IgG against the full transmembrane Spike protein increased it (OR=1.53, 95% CI 1.14-2.05). Convalescent plasma did not reduce the risk of intubation or death at 30 days among hospitalized patients with COVID-19. Transfusion of convalescent plasma with unfavourable antibody profiles may be associated with worse clinical outcomes compared to standard care.

Background: Proton pump inhibitors are effective for functional dyspepsia but ineffective in relieving postprandial distress syndrome. Curcuma longa might be effective for postprandial distress syndrome. The objective of this study was to compare the efficacy of Curcuma longa and simethicone for postprandial distress syndrome in an open-label randomized-controlled trial. Methods: This trial was conducted between July 2018 and February 2019. In total, 78 patients were randomly assigned to receive 4 weeks of treatment with 750 or 1,500 mg oral Curcuma longa per day or 240 mg simethicone per day. The patients assessed their symptoms using the dyspepsia Global Overall Symptom scale at baseline, week 2, and week 4. After stopping medication for 2 weeks, the patients assessed recurrent symptoms and day of recurrence by themselves at the end of week 6. Results: In total, 78 patients underwent randomization (27 in 750 mg Curcuma longa, 26 in 1500 mg Curcuma longa, and 25 in simethicone groups). After 2 weeks, there were no significant differences in all mean changes of symptoms scores (95%CI) of postprandial distress syndrome [-4.1 (-4.5, -2.6) vs -4.3 (-5.2, -3.3) vs -4.2 (-4.8, -3.5), P=0.954]. Over a period of 4 weeks, the reduction in mean scores was greater among participants receiving simethicone (although not statistically significant) compared with two intervention groups [-4.6 (-5.7, -3.6) vs -5.4 (-6.6, -4.1) vs -6.2 (-7.2, -5.2), P=0.122]. The rate of recurrence was significantly lower in simethicone than the two Curcuma longa groups (42.9 vs 45.5 vs 13.6%, P=0.047). There was no serious adverse event reported in all three groups. Conclusions: Curcuma longa had a similar effect on treatment outcomes to simethicone after 2 and 4 weeks, but the recurrence rate of symptoms was significantly higher without serious adverse events.

AbstractImportanceNovel SARS-CoV-2 virus has infected nearly half a billion people across the world and is highly contagious. There is a need for a novel mechanism to block viral entry and stop its replication.BackgroundSpike protein N terminal domain (NTD) of the novel SARS-CoV-2 is essential for viral entry and replication in human cell. Thus the S1 NTD of human coronavirus family, which is similar to a galectin binding site - human galactose binding lectins, is a potential novel target for early treatment in COVID-19.ObjectivesTo study the feasibility of performing a definitive trial of using galectin antagonist – Prolectin-M as treatment for mild, symptomatic, rRT-PCR positive, COVID-19.Main outcomes and measuresCycle threshold (Ct) value is number of cycles needed to express fluorescence, on real time reverse transcriptase polymerase chain reaction. Ct values expressed for RNA polymerase (Rd/RP) gene +Nucleocapsid gene and the small envelope (E) genes determine infectivity of the individual. A digital droplet PCR based estimation of the Nucleocapid genes (N1+N2) in absolute copies/μL determines active viral replication.Design and interventionPilot Feasibility Randomised Controlled Open-Label, parallel arm, study. Oral tablets of Prolectin-M were administered along with the best practice, Standard of Care (SoC) and compared against SoC. Voluntarily, consenting individuals, age >18 years, and able to provide frequent nasopharyngeal and oropharyngeal swabs were randomly allocated by REDCap software.The intervention, Prolectin-M was administered as a multi dose regime of 4 gram tablets. Each tablet contained 2 grams of (1-6)-Alpha-D-mannopyranosil mixed with 2 grams of dietary fibre. Each participant took a single chewable tablet every hour, to a maximum of 10 hours in a day. Tablets were administered only during the daytime, for total of 5 days.ResultsThis pilot trial demonstrated the feasibility to recruit and randomize participants. By day 7, following treatment with Prolectin-M, Ct value of Rd/Rp + N gene increased by16.41 points, 95% (CI – 0.3527 to 32.48, p=0.047). Similarly, small envelope (E) gene also increased by 17.75 points (95% CI;-0.1321 to 35.63, p = 0.05). The expression of N1, N2 genes went below detectable thresholds by day 3 (Mann Whitney U = 0.000, p<0.029).rRT-PCR testing done in the clinic on day 1, 7, and 14 had 3 participants (60%) turn negative by day 7 and all turned negative by day 14 and stayed negative until day 28. In the SoC group 2 participants had zero detectable viral loads at baseline, 2 participants tested negative on day 14, and the last participant tested remained positive on day 28. There were no serious adverse events, and all participants were clinically asymptomatic before day 28 with reactive immunoglobulin G (IgG).Trial relevanceThis pilot study proves that it is feasible and safe to perform a trial using a Galectin antagonist in COVID-19. This is a novel mechanism for blocking viral entry and its subsequent replication.Trial RegistrationClinical Trials.gov identifier NCT04512027; CTRI ref. CTRI/2020/09/027833

Abstract Background The substitution of moxifloxacin for ethambutol produced promising results for improved tuberculosis treatment outcomes. Methods We conducted an open-label, randomized trial to test whether a moxifloxacin-containing treatment regimen was superior to the standard regimen for the treatment of recurrent tuberculosis. The primary and secondary outcomes were the sputum culture conversion rate at the end of 8 weeks and the proportion of participants with a favorable outcome, respectively. Results We enrolled 196 participants; 69.9% were male and 70.4% were co-infected with human immunodeficiency virus (HIV). There was no significant difference between the study groups in the proportion of patients achieving culture conversion at the end of 8 weeks (83.0% [moxifloxacin] vs 78.5% [control]; P = .463); however, the median time to culture conversion was significantly shorter (6.0 weeks, interquartile range [IQR] 4.0–8.3) in the moxifloxacin group than the control group (7.9 weeks, IQR 4.0– 11.4; P = .018). A favorable end-of-treatment outcome was reported in 86 participants (87.8%) in the moxifloxacin group and 93 participants (94.9%) in the control group, for an adjusted absolute risk difference of −5.5 (95% confidence interval −13.8 to 2.8; P = .193) percentage points. There were significantly higher proportions of participants with Grade 3 or 4 adverse events (43.9% [43/98] vs 25.5% [25/98]; P = .01) and serious adverse events (27.6% [27/98] vs 12.2% [12/98]; P = .012) in the moxifloxacin group. Conclusions The replacement of ethambutol with moxifloxacin did not significantly improve either culture conversion rates at the end of 8 weeks or treatment success, and was associated with a higher incidence of adverse events. Clinical Trials Registration NCT02114684.
