Community case management of severe pneumonia with oral amoxicillin in children aged 2-59 months in Haripur district, Pakistan: a cluster randomised trial.

ABSTRACT:

Background

First dose oral co-trimoxazole and referral are recommended for WHO-defined severe pneumonia. Difficulties with referral compliance are reported in many low-resource settings, resulting in low access to appropriate treatment. The objective in this study was to assess whether community case management by lady health workers (LHWs) with oral amoxicillin in children with severe pneumonia was equivalent to current standard of care.

Methods

In Haripur district, Pakistan, 28 clusters were randomly assigned with stratification in a 1:1 ratio to intervention and control clusters by use of a computer-generated randomisation sequence. Children were included in the study if they were aged 2-59 months with WHO-defined severe pneumonia and living in the study area. In the intervention clusters, community-based LHWs provided mothers with oral amoxicillin (80-90 mg/kg per day or 375 mg twice a day for infants aged 2-11 months and 625 mg twice a day for those aged 12-59 months) with specific guidance on its use. In control clusters, LHWs gave the first dose of oral co-trimoxazole (age 2-11 months, sulfamethoxazole 200 mg plus trimethoprim 40 mg; age 12 months to 5 years, sulfamethoxazole 300 mg plus trimethoprim 60 mg) and referred the children to a health facility for standard of care. Participants, carers, and assessors were not masked to treatment assignment. The primary outcome was treatment failure by day 6. Analysis was per protocol with adjustment for clustering within groups by use of generalised estimating equations. This study is registered, number ISRCTN10618300.

Findings

We assigned 1995 children to treatment in 14 intervention clusters and 1477 in 14 control clusters, and we analysed 1857 and 1354 children, respectively. Cluster-adjusted treatment failure rates by day 6 were significantly reduced in the intervention clusters (165 [9%] vs 241 [18%], risk difference -8·9%, 95% CI -12·4 to -5·4). Further adjustment for baseline covariates made little difference (-7·3%, -10·1 to -4·5). Two deaths were reported in the control clusters and one in the intervention cluster. Most of the risk reduction was in the occurrence of fever and lower chest indrawing on day 3 (-6·7%, -10·0 to -3·3). Adverse events were diarrhoea (n=4) and skin rash (n=1) in the intervention clusters and diarrhoea (n=3) in the control clusters.

Interpretation

Community case management could result in a standardised treatment for children with severe pneumonia, reduce delay in treatment initiation, and reduce the costs for families and health-care systems.

Project description:BackgroundPneumonia is the leading cause of mortality in under-five children and most of these deaths occur in South-East Asia and Africa. Fast breathing pneumonia if not treated can progress to lower chest indrawing pneumonia. Treatment recommendation by the World Health Organization (WHO) for fast-breathing pneumonia includes oral amoxicillin and cotrimoxazole (as an alternative). Due to limited access to health care facilities and skilled health care workers, many children are unable to receive antibiotics. Algorithm-based community case management of pneumonia through trained community health workers has resulted in a decline in morbidity and mortality in low- and middle-income countries (LMIC).MethodsIt was a cluster-randomized, unblinded, community-based trial conducted in the Matiari district of Sindh province, Pakistan. Lady Health Workers (LHWs) were trained in assessing, classifying, and managing fast-breathing pneumonia cases (Respiratory rate of >50 breaths/min) at home with oral amoxicillin for three days and with co-trimoxazole for five days in the intervention and control arms respectively. Children with fast-breathing pneumonia were screened by LHWs and were validated by the study by Community Health Workers (CHWs) within 48 hours. They were followed by the LHWs on days 2, 4, and 14 in intervention and on days 2, 6, and 14 in the control arm. Primary treatment failure was assessed on day 4 in intervention and day 6 in the control arm. A severe pneumonia trial was registered with ClinicalTrials.gov, number NCT01192789.ResultsFrom February 2008 to March 2010, a total of 5876 children were enrolled by Lady Health Workers as fast breathing pneumonia. On validation visits of the CHWs, 728 (12%) children were excluded. A total of 4984 children were analysed as per protocol: 2480 in intervention and 2504 in control. There were 72 (2.9%) primary treatment failures in the intervention arm as compared to 102 (4%) in the control arm with a risk difference of -0.94 (-2.84%, 0.96%). Secondary treatment failures were almost equal in both arms (4 vs 7 cases). No deaths or serious adverse events were recorded.ConclusionsThis study shows that amoxicillin can be as effective as cotrimoxazole to treat fast-breathing pneumonia cases at the domiciliary level.RegistrationNCT01192789.

Project description:ImportancePneumonia is the leading infectious killer of children. Rigorous evidence supporting antibiotic treatment of children with nonsevere fast-breathing pneumonia in low-resource African settings is lacking.ObjectiveTo assess whether treatment with placebo for nonsevere fast-breathing pneumonia is substantively less effective than 3 days of treatment with amoxicillin.Design, setting, and participantsThis double-blind, 2-arm, randomized clinical noninferiority trial with follow-up of 14 days screened 1343 HIV-uninfected children aged 2 to 59 months with nonsevere fast-breathing pneumonia at outpatient departments of hospitals in Lilongwe, Malawi, Africa, between June 2016 and June 2017.InterventionsPlacebo or amoxicillin dispersible tablets administered twice daily for 3 days.Main outcomes and measuresThe primary end point was the proportion of children failing treatment by day 4 with a relative noninferiority margin of 1.5 times the failure rate in the amoxicillin group. Primary analyses were performed based on the intention-to-treat principle. Planned secondary analyses included treatment failure or relapse by day 14.ResultsIn total, 1126 children were randomized to 3 days of amoxicillin (n = 564) or placebo (n = 562) therapy. Baseline demographic and clinical characteristics were similar between the groups. For the entire study population, the mean (SD) age was 21.3 (15.1) months, and 601 (53.4%) were female. After an interim analysis, the data safety monitoring board stopped the study because children receiving amoxicillin had a 4.0% (22 of 552 with outcome data) treatment failure rate by day 4, whereas children receiving placebo had a 7.0% (38 of 543) treatment failure rate (adjusted relative risk, 1.78; 95% CI, 1.07%-2.97%; adjusted absolute difference, 3.0%; 95% CI, 0.4%-5.7%). Among children with known day 14 outcomes, 56 of 552 (10.1%) receiving amoxicillin and 64 of 543 (11.8%) receiving placebo had either treatment failure by day 4 or relapse by day 14 (relative risk, 1.16; 95% CI, 0.83%-1.63%; absolute difference, 1.6%; 95% CI, -2.1% to 5.4%). There were no deaths.Conclusions and relevanceIn HIV-uninfected children aged 2 to 59 months in a malaria-endemic region of Malawi, placebo treatment of nonsevere fast-breathing pneumonia was significantly inferior to treatment with amoxicillin. However, by day 4, approximately 93% of children receiving placebo were without treatment failure, and there was no significant difference between groups in treatment failure or relapse by day 14. The number of children with nonsevere fast-breathing pneumonia that needed amoxicillin treatment for 1 child to benefit was 33.Trial registrationClinicalTrials.gov Identifier: NCT02760420.

Project description:BackgroundPneumonia is a leading cause of morbidity and mortality in children younger than five years of age. Most deaths occur during infancy and in low-income countries. Daily zinc supplements have been reported to prevent acute lower respiratory tract infection (LRTI) and reduce child mortality. This is an update of a review first published in 2010.ObjectivesTo evaluate the effectiveness of zinc supplementation in the prevention of pneumonia in children aged two to 59 months.Search methodsWe searched CENTRAL (Issue 21 October 2016), MEDLINE (1966 to October 2016), Embase (1974 to October 2016), LILACS (1982 to October 2016), CINAHL (1981 to October 2016), Web of Science (1985 to October 2016) and IMSEAR (1980 to October 2016).Selection criteriaRandomised controlled trials (RCTs) evaluating zinc supplementation for the prevention of pneumonia in children aged from 2 months to 59 months.Data collection and analysisTwo review authors independently assessed trial quality and extracted data.Main resultsWe did not identify any new studies for inclusion in this update. We included six studies that involved 5193 participants.Analysis showed that zinc supplementation reduced the incidence of pneumonia by 13% (fixed-effect risk ratio (RR) 0.87; 95% confidence interval (CI) 0.81 to 0.94, six studies, low-quality evidence) and prevalence of pneumonia by 41% (random-effects RR 0.59; 95% CI 0.35 to 0.99, one study, n = 609, low-quality evidence). On subgroup analysis, we found that zinc reduced the incidence of pneumonia defined by specific clinical criteria by 21% (i.e. confirmation by chest examination or chest radiograph) (fixed-effect RR 0.79; 95% CI 0.0.71 to 0.88, four studies, n = 3261), but had no effect on lower specificity pneumonia case definition (i.e. age-specific fast breathing with or without lower chest indrawing) (fixed-effect RR 0.95; 95% CI 0.86 to 1.06, four studies, n = 1932).Authors' conclusionsZinc supplementation in children is associated with a reduction in the incidence and prevalence of pneumonia.

Project description:Pneumonia is the leading cause of child mortality under five years of age worldwide. For pneumonia with chest indrawing in children aged 3-59 months, injectable penicillin and hospitalization was the recommended treatment. This increased the health care cost and exposure to nosocomial infections. We compared the clinical and cost outcomes of a seven day treatment with oral amoxicillin with the first 48 h of treatment given in the hospital (hospital group) or at home (home group).We conducted an open-label, multi-center, two-arm randomized clinical trial at six tertiary hospitals in India. Children aged 3 to 59 months with chest indrawing pneumonia were randomized to home or hospital group. Clinical outcomes, treatment adherence, and patient safety were monitored through home visits on day 3, 5, 8, and 14 with an additional visit for the home group at 24 h. Clinical outcomes included treatment failure rates up to 7 days (primary outcome) and between 8-14 days (secondary outcome) using the intention to treat and per protocol analyses. Cost outcomes included direct medical, direct non-medical and indirect costs for a random 17% subsample using the micro-costing technique.1118 children were enrolled and randomized to home (n = 554) or hospital group (n = 564). Both groups had similar baseline characteristics. Overall treatment failure rate was 11.5% (per protocol analysis). The hospital group was significantly more likely to fail treatment than the home group in the intention to treat analysis. Predictors with increased risk of treatment failure at any time were age 3-11 months, receiving antibiotics within 48 h prior to enrolment and use of high polluting fuel. Death rates at 7 or 14 days did not differ significantly. (Difference -0.0%; 95% CI -0.5 to 0.5). The median total treatment cost was Rs. 399 for the home group versus Rs. 602 for the hospital group (p < 0.001), for the same effect of 5% failure rate at the end of 7 days of treatment in the random subsample.Home based oral amoxicillin treatment was equivalent to hospital treatment for first 48 h in selected children of chest indrawing pneumonia and was cheaper. Consistent with the recent WHO simplified guidelines, management with home based oral amoxicillin for select children with only fast breathing and chest-indrawing can be a cost effective intervention.ClinicalTrials.gov NCT01386840, registered 25th June 2011 and the Indian Council of Medical Research REFCTRI/2010/000629.

Project description:BackgroundThe World Health Organization (WHO) recommends oral amoxicillin for patients who have pneumonia with tachypnea, yet trial data indicate that not using amoxicillin to treat this condition may be noninferior to using amoxicillin.MethodsWe conducted a double-blind, randomized, placebo-controlled noninferiority trial involving children at primary health care centers in low-income communities in Karachi, Pakistan. Children who were 2 to 59 months of age and who met WHO criteria for nonsevere pneumonia with tachypnea were randomly assigned to a 3-day course of a suspension of amoxicillin (the active control) of 50 mg per milliliter or matched volume of placebo (the test regimen), according to WHO weight bands (500 mg every 12 hours for a weight of 4 to <10 kg, 1000 mg every 12 hours for a weight of 10 to <14 kg, or 1500 mg every 12 hours for a weight of 14 to <20 kg). The primary outcome was treatment failure during the 3-day course of amoxicillin or placebo. The prespecified noninferiority margin was 1.75 percentage points.ResultsFrom November 9, 2014, through November 30, 2017, a total of 4002 children underwent randomization (1999 in the placebo group and 2003 in the amoxicillin group). In the per-protocol analysis, the incidence of treatment failure was 4.9% among placebo recipients (95 of 1927 children) and 2.6% among amoxicillin recipients (51 of 1929 children) (between-group difference, 2.3 percentage points; 95% confidence interval [CI], 0.9 to 3.7). Results were similar in the intention-to-treat analysis. The presence of fever and wheeze predicted treatment failure. The number needed to treat to prevent one treatment failure was 44 (95% CI, 31 to 80). One patient (<0.1%) in each group died. Relapse occurred in 40 children (2.2%) in the placebo group and in 58 children (3.1%) in the amoxicillin group.ConclusionsAmong children younger than 5 years of age with nonsevere pneumonia, the frequency of treatment failure was higher in the placebo group than in the amoxicillin group, a difference that did not meet the noninferiority margin for placebo.

Project description:BackgroundPneumonia 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.ObjectiveThe 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.MethodsThis 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.ResultsEnrollment 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.ConclusionsOur study's findings will improve compliance with the use of antibiotics that require less frequent doses for the treatment of severe pneumonia.Trial registrationClinicalTrials.gov NCT03369093; https://clinicaltrials.gov/ct2/show/NCT03369093.International registered report identifier (irrid)DERR1-10.2196/17735.

Project description:BackgroundThe utilization of plants and plant resources for various ethnobotanical purposes is a common practice in local towns and villages of developing countries, especially in regard to human and veterinary healthcare. For this reason, it is important to unveil and document ethnomedicinal plants and their traditional/folk usage for human and livestock healthcare from unexplored areas. Here we advance our findings on ethnomedicinal plants from Haripur District, Pakistan, not only for conservation purposes, but also for further pharmacological screenings and applied research.MethodologyInformation of ethnomedicinal plants was obtained using a carefully planned questionnaire and interviews from 80 local people and traditional healers (Hakims) in Haripur District, Pakistan, from 2015 to 2017. Informed consent was obtained from each participant before conducting the interview process. Quantitative ethnobotanical indices, such as relative frequency of citation (RFC), use value (UV) and Jaccard index (JI), were calculated for each recorded species. Correlation analysis between the RFC and UV was tested by Pearson's correlation, SPSS (ver. 16).ResultsA total of 80 plant species (33 herbs, 24 trees, 21 shrubs and 2 climbers) belonging to 50 families were being used in the study area to treat livestock and human diseases. Lamiaceae was the most dominant family with 7 species (8.7%), followed by Fabaceae with 6 species (7.5%), and Moraceae with 5 species (6.2%). Local people used different methods of preparation for different plant parts; among them, decoction/tea (22 species) was the popular method, followed by powder/grained (20 species) and paste/poultice (14 species). It was observed that most of the species (~ 12 to 16 species) were utilized to treat human and livestock digestive system-related problems, respectively. The Jaccard index found that plant usage in two studies (District Abbottabad and Sulaiman Range) was more comparable. Local people mainly relied on folk medicines due to their rich accessibility, low cost and higher efficacy against diseases. Unfortunately, this important traditional knowledge is vanishing fast, and many medicinal plants are under severe threat. The most threats associated to species observed in the study area include Dehri, Garmthun, Baghpur, Najafpur and Pharala.ConclusionThe study has indicated that local people have higher confidence in the usage of ethnomedicinal plants and are still using them for the treatment of various ailments. Comparative analysis with other studies may strongly reflected the novel use of these plants, which may be due to the deep-rooted and unique socio-cultural setup of the study area. However, awareness campaigns, conservation efforts and pharmacological and applied research are required for further exploration and may be a step in the right direction to unveil prospective pharmaceuticals.
