Substantial and sustained reduction in under-5 mortality, diarrhea, and pneumonia in Oshikhandass, Pakistan: evidence from two longitudinal cohort studies 15 years apart.

BACKGROUND: Oshikhandass is a rural village in northern Pakistan where a 1989-1991 verbal autopsy study showed that diarrhea and pneumonia were the top causes of under-5 mortality. Intensive surveillance, active community health education and child health interventions were delivered in 1989-1996; here we assess improvements in under-5 mortality, diarrhea, and pneumonia over this period and 15 years later. METHODS: Two prospective open-cohort studies in Oshikhandass from 1989 to 1996 (Study 1) and 2011-2014 (Study 2) enrolled all children under age 60 months. Study staff trained using WHO guidelines, conducted weekly household surveillance and promoted knowledge on causes and management of diarrhea and pneumonia. Information about household characteristics and socioeconomic status was collected. Hurdle models were constructed to examine putative risk factors for diarrhea and pneumonia. RESULTS: Against a backdrop of considerable change in the socioeconomic status of the community, under-5 mortality, which declined over the course of Study 1 (from 114.3 to 79.5 deaths/1000 live births (LB) between 1989 and 1996), exceeded Sustainable Development Goal 3 by Study 2 (19.8 deaths/ 1000 LB). Reductions in diarrhea prevalence (20.3 to 2.2 days/ Child Year [CY]), incidence (2.1 to 0.5 episodes/ CY), and number of bloody diarrhea episodes (18.6 to 5.2%) seen during Study 1, were sustained in Study 2. Pneumonia incidence was 0.5 episodes /CY in Study 1 and 0.2/CY in Study 2; only 5% of episodes were categorized as severe or very severe in both studies. While no individual factors predicted a statistically significant difference in diarrhea or pneumonia episodes, the combined effect of water, toilet and housing materials was associated with a significant decrease in diarrhea; higher household income was the most protective factor for pneumonia in Study 1. CONCLUSIONS: We report a 4-fold decrease in overall childhood mortality, and a 2-fold decrease in childhood morbidity from diarrhea and pneumonia in a remote rural village in Pakistan between 1989 and 2014. We conclude that significant, sustainable improvements in child health may be achieved through improved socioeconomic status and promoting interactions between locally engaged health workers and the community, but that continued efforts are needed to improve health worker training, supervision, and the rational use of medications. TRIAL REGISTRATION: Not Applicable.

Response to cotrimoxazole in the management of childhood pneumonia in first-level health care facilities.

BACKGROUND: Reports of high levels of antimicrobial resistance to cotrimoxazole in children with non-severe pneumonia (NSP) have prompted calls for a change to amoxicillin in the therapeutic guidelines at the first-level health care facility (FLHF). FLHFs lack data about the use of World Health Organization (WHO) acute respiratory infection (ARI) standard case management (SCM). OBJECTIVE: To apply ARI SCM guidelines at the FLHF, assess clinical outcome of NSP with oral cotrimoxazole and determine the risk factors influencing treatment outcome. DESIGN: Health care workers (HCWs) at 14 health centres managed children aged 2-59 months with NSP according to ARI SCM guidelines. The primary outcome was treatment failure, including change of antibiotic therapy and loss to follow-up. RESULTS: Of 949 children enrolled, 110 (11.6%) failed therapy with oral cotrimoxazole. Clinical failure was significantly higher among children presenting with a fast respiratory rate of > or = 15 breaths/min above normal for age and wheezing on examination. CONCLUSIONS: To treat children with NSP at the FLHF, oral cotrimoxazole is an acceptable treatment choice in view of the efficacy, cost and ease of use. In children with wheezing and signs of pneumonia, the decision to use antibiotic therapy should be made after a trial of bronchodilator therapy.

Evaluation of dowdo (wheat-milk gruel) in children with acute diarrhoea.

Appropriate feeding practices have an important impact on diarrhoeal disease management in developing countries. We evaluated the efficacy of feeding dowdo, a wheat-milk gruel, traditionally used as a weaning food in the Northern Areas of Pakistan. Dowdo was compared with khitchri, a rice-lentil mixture, in acute diarrhoea through a randomized trial. Seventy- six children between 6 and 36 months of age, with acute watery diarrhoea of less than seven days were recruited. After rehydration with standard World Health Organization (WHO) glucose-based oral rehydration solution or intravenous Ringers lactate, patients were randomly assigned to either diet group. Dowdo and Khitchri were found to be equally effective in terms of stool frequency and output, duration of diarrhoea, weight gain and duration of hospitalization. The results indicate that feeding dowdo was as effective as khitchri in children with acute diarrhoea. Additionally, acceptability of dowdo was better than Khitchri. It is recommended that dowdo be used for nutritional management of diarrhoeal disease in children in the Northern Areas of Pakistan.
