Risk Factors and Outcomes of Hospital Acquired Pneumonia in Young Bangladeshi Children

Hospital acquired pneumonia (HAP) is common and often associated with high mortality in children aged five or less. We sought to evaluate the risk factors and outcome of HAP in such children. We compared demographic, clinical, and laboratory characteristics in children <5 years using a case control design during the period of August 2013 and December 2017, where children with HAP were constituted as cases (n = 281) and twice as many randomly selected children without HAP were constituted as controls (n = 562). HAP was defined as a child developing a new episode of pneumonia both clinically and radiologically after at least 48 h of hospitalization. A total of 4101 children were treated during the study period. The mortality was significantly higher among the cases than the controls (8% vs. 4%, p = 0.014). In multivariate logistic regression analysis, after adjusting for potential confounders, it was found that persistent diarrhea (95% CI = 1.32–5.79; p = 0.007), severe acute malnutrition (95% CI = 1.46–3.27; p < 0.001), bacteremia (95% CI = 1.16–3.49; p = 0.013), and prolonged hospitalization of >5 days (95% CI = 3.01–8.02; p < 0.001) were identified as independent risk factors for HAP. Early identification of these risk factors and their prompt management may help to reduce HAP-related fatal consequences, especially in resource limited settings.

Green Banana mixed Diet is Beneficial in the Management of Childhood Persistent Diarrhea: an Open, Randomized-Controlled Trial (Preprint)

BACKGROUND Persistent diarrhea (PD), diarrhea for ≥14 days, accounts for 36%-56% of all diarrhea-related death. Studies demonstrated that green banana helps in the resolution of diarrhea. OBJECTIVE We assessed whether a lactose-free diet rice suji (RS) or rice suji containing green banana (GB-RS), improves outcome compared with 3/4th strength rice suji (3/4th RS) in 6 to 35 months old children having PD in the icddr,b Dhaka hospital. METHODS In this open-labeled, randomized, controlled trial, children with PD not improving with milk suji (the initial diet) received any of the three study diets: GB-RS, RS, 3/4th RS. The primary outcome was the percentage of children who recovered from diarrhea by day 5 with an intention to treat analysis. RESULTS From 1st December 2017 to 31st August 2019, we randomly allocated 45 children to each group. By day 5, 66 children recovered from PD, of whom 26 (58%), 14 (31%), 26 (58%) received GB-RS, RS, and 3/4th RS respectively. Significantly more resolution of PD occurred in GB-RS and 3/4th RS groups compared to RS group [relative risk (RR) 1⸱71, 95% CI 1⸱19-2⸱60; p=0⸱019]. Two (10%) children died, one each in RS group and GB-RS group. TaqMan array card (TAC) identified EAEC, rotavirus, norovirus, EPEC, astrovirus, and Campylobacter as the major pathogens associated with PD. CONCLUSIONS GB-RS and 3/4th RS are efficacious in the management of PD in young children. We also demonstrated a wide range of entero-pathogen associated with PD by TAC which needs further study to find a causal link.

Nitroreductase Activites in Giardia lamblia: ORF 17150 Encodes a Quinone Reductase with Nitroreductase Activity

The intestinal diplomonadid Giardia lamblia is a causative agent of persistent diarrhea. Current treatments are based on nitro drugs, especially metronidazole. Nitro compounds are activated by reduction, yielding toxic intermediates. The enzymatic systems responsible for this activation are not completely understood. By fractionating cell free crude extracts by size exclusion chromatography followed by mass spectrometry, enzymes with nitroreductase (NR) activities are identified. The protein encoded by ORF 17150 found in two pools with NR activities is overexpressed and characterized. In pools of fractions with main NR activities, previously-known NRs are identified, as well as a previously uncharacterized protein encoded by ORF 17150. Recombinant protein 17150 is a flavoprotein with NADPH-dependent quinone reductase and NR activities. Besides a set of previously identified NRs, we have identified a novel enzyme with NR activity.

Cow's Milk and Egg Allergy Presented With Chronic Diarrhea, Case Report

Persistent diarrhea in infancy, is one of the most common complaints form of food allergies. When the patient's histories are not detailed, they can be easily overlooked and they are tried to be controlled with general gastroenteritis treatments. In this case report, cow's milk and egg allergy was mentioned which is detected by the symptoms of persistant diarrhea, iron deficiency anemia and growth retardation. In this respect, we aimed to emphasize that primary care physicians should evaluate food allergy in the differential diagnosis when they encounter infants and children with persistent diarrhea and growth retardation.
