Health and nutritional status of children hospitalized during the COVID-19 pandemic, Bangladesh.

OBJECTIVE: To compare the health and nutrition of children younger than 5 years admitted to hospital during and before the coronavirus disease 2019 (COVID-19) pandemic in Bangladesh. METHODS: We collected data from hospital records of children 0-59 months admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh in March 2020-February 2021 (COVID-19 period; n = 2552) and March 2019-February 2020 (pre-COVID-19 period; n = 6738). Data collected included sociodemographic, anthropometric, clinical and biochemical characteristics. We compared these data for child admissions in the COVID-19 and pre-COVID-19 periods, including infants 0-11 months born during and before the pandemic and admitted to hospital. FINDINGS: Admissions of children as a percentage of total admissions were lower in March 2020 (2.47%; 63/2552) than March 2019 (8.30%; 559/6738), but increased to 20.61% (526/2552) in February 2021, three times greater than in the pre-COVID-19 period (6.69%; 451/6738). Children admitted during the COVID-19 period were significantly more likely to have dehydration, severe sepsis or septic shock, convulsions, hypernatraemia and raised creatinine than children admitted before the pandemic (P < 0.05). In infants < 6 months and those born during the pandemic, stunting and wasting were significantly higher than in infants in the pre-COVID-19 period (P < 0.05). The risk of death was higher in infants < 6 months during the pandemic (odds ratio: 1.66; 95% confidence interval: 0.95-2.92). CONCLUSION: During the pandemic, children presented with more severe illness and poorer nutrition. Efforts are needed to reduce the adverse effects of the pandemic on the health and well-being of children.

New formulation zinc sulphate acceptability and adherence in children with acute diarrhoea: A prospective, open-label, interventional study in Bangladesh.

AIM: Zinc is an adjunct to oral rehydration salts for management of diarrhoea in children. Due to zinc's unpleasant taste, children often develop nausea and/or vomiting. We aimed to assess acceptability (tolerability) and adherence of improvised formulation of zinc tablet among under-five children with acute diarrhoea. METHODS: This was an open-label intervention trial among 3-59 months old diarrhoeal children attending the outpatient department of Dhaka Hospital, who were enrolled in two age strata, 3 to <18 months and 18-59 months. Zinc tablets 10 or 20 mg per day were prescribed for a total of 10 days for <6 months and ≥6 months age children respectively, with follow-up. Diary-cards were used to record events. RESULTS: In stratum 1, 158 (90.8%) children and in stratum 2, 144 (95.4%) children completed the study as per protocol out of 325 enrolled children. Sociodemographic, clinical and anthropometric measurements were comparable in the two strata except admission diarrhoeal duration (median 3 days vs. 2 days, P = 0.001). Adherence to 10 days treatment was 123 (77.8%) in stratum 1 and 127 (88.2%) in stratum 2. Zinc tablets were tolerated very well/well in 280 (92.7%) children. Vomiting, regurgitation and nausea were observed in 99 (32.8%), 59 (19.5%) and 22 (7.4%) children respectively. Caregivers' willingness to use the same drug in future was 300 (99.3%) among all children. CONCLUSION: Our study findings demonstrate that modified taste and formulation zinc tablets were well tolerated, and caregivers' willingness to use this formulation in future supports its acceptability, adherence and palatability.

Use of TaqMan Array Cards to investigate the aetiological agents of diarrhoea among young infants with severe acute malnutrition.

OBJECTIVE: Studies involving less sensitive conventional microscopy and culture-based approaches have identified distinct differences in diarrhoeal aetiology in childhood malnutrition. Our study involved the use of an advanced molecular biology technique, the TaqMan Array Cards (TAC), to elucidate the diarrhoeal aetiology among young infants with severe acute malnutrition (SAM). METHOD: A total of 113 faecal samples was collected from SAM infants, aged 2-6 months, upon admission to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) with complications of diarrhoea and related comorbidities. We used TAC for the detection of 29 different diarrhoeal enteropathogens from a single faecal sample. For comparison, we also analysed 25 diarrhoeal samples from well-nourished infants of similar age. RESULTS: Higher odds of detection of all bacterial enteropathogens were associated with diarrhoea among SAM infants. In particular, the detection of Aeromonas sp (aOR: 25.7, p = 0.011), Campylobacter sp (aOR: 9.6, p < 0.01) and ETEC (aOR: 5.2, p = 0.022) was significantly associated with diarrhoea among SAM infants in comparison to well-nourished infants. 80% higher odds of detection of rotavirus and norovirus GII were associated with diarrhoea among well-nourished infants in comparison to SAM infants (aOR: 0.2, p < 0.05). CONCLUSION: Our study findings demonstrate a difference in diarrhoeal aetiology among SAM and well-nourished young infants, which may be useful in providing an evidence-based logic for possible revision of treatment guidelines for treatment of young diarrhoeal infants with SAM in the early management of the menace of antimicrobial resistance.

Antibiotic exposure among young infants suffering from diarrhoea in Bangladesh.

AIMS: Appropriate rehydration has always been significant in treating diarrhoeal diseases in children. Irrational antibiotic use among diarrhoeal children has remained a major public health concern. Information regarding antibiotic use in young infants suffering from diarrhoea is very limited and a unique aspect of research. We aimed to investigate the prevalence of antibiotic use in the community among 2-6 months infants with diarrhoeal illnesses and having different nutritional status. METHODS: We investigated a total of 5279 infants aged 2-6 months at Dhaka hospital, International Centre for Diarrhoeal Disease Research, Bangladesh, between September 2018 and June 2019. Among them, 257 infants were suffering from severe acute malnutrition (SAM). History of taking antibiotics was ascertained by direct observation of a prescription by a physician, the bottle of antibiotic or asking the caregiver about the name of antibiotic or its price that is very close to the usual market price of an antibiotic. RESULTS: Overall, 52% of infants received antibiotics before hospital admission. Non-SAM infants had higher odds of receiving antibiotics (adjusted odds ratio [aOR] = 1.52, 95% confidence interval: 1.18, 1.97, P value = 0.003) compared to infants with SAM and use of antibiotics increased with age (aOR = 1.11, 95% confidence interval: 1.06, 1.17, P value<0.001). Commonly used antibiotics were azithromycin (13.3%), ciprofloxacin (7.7%), erythromycin (7.7%) and metronidazole (2.6%). The proportion of receiving ciprofloxacin was significantly lower in infants with SAM compared to their non-SAM counterparts (2.7% vs. 7.97%, P value = 0.004). CONCLUSIONS: The study underscores the excessive use of antibiotics among diarrhoeal infants, which is already a major public health concern in low- and middle-income countries.

Effect of a water, sanitation and hygiene program on handwashing with soap among household members of diarrhoea patients in healthcare facilities in Bangladesh: a cluster-randomised controlled trial of the CHoBI7 mobile health program.

OBJECTIVE: The Cholera-Hospital-Based-Intervention-for-7-days (CHoBI7) is a water treatment and handwashing with soap intervention for diarrhoea patients and their household members which is initially delivered in a healthcare facility setting. This study evaluated the effectiveness of CHoBI7 program delivery in increasing handwashing with soap in a healthcare facility setting among diarrhoea patients and their household members. METHODS: A randomised controlled trial of the CHoBI7 program was conducted among 404 diarrhoea patients and their accompanying household members in healthcare facilities in Dhaka, Bangladesh. The 'Standard Message' Arm received the standard message given in Bangladesh to diarrhoea patients on the use of oral rehydration solution. The 'Health Facility Visit + Soapy Water' Arm received the standard message, the CHoBI7 communication module delivered bedside to the patient; and a soapy water bottle in the healthcare facility. The 'Health Facility Visit + Handwashing Station' Arm received this same intervention plus a small plastic handwashing station. Within 24 h of intervention delivery, three-hour structured observation of handwashing practices at stool/vomit- and food-related events (key events) was conducted in healthcare facilities of diarrhoea patients and their accompanying household members. RESULTS: Compared to the Standard Message Arm, there was significantly more handwashing with soap at key events in both the Health Facility Visit + Soapy Water Arm (51% vs. 25 %) (Odds Ratio: 3.02; (95% Confidence Interval (CI): 1.41, 6.45) and the Health Facility Visit + Handwashing Station Arm (58% vs. 25%) OR: 4.12; (95% CI: 1.86, 9.14). CONCLUSION: These findings demonstrate that delivery of the CHoBI7 communication module and provision of a soapy water bottle to diarrhoea patients and their accompanying household members presents a promising approach to increase handwashing with soap among this high risk population in a healthcare facility setting in Bangladesh.

OBJECTIF: Le programme (CHoBI7Cholera-Hospital-Based-Intervention-for-7-days) est une intervention de traitement de l'eau et de lavage des mains avec du savon pour les patients et les membres de leur famille qui est initialement administrée dans un établissement de santé. Cette étude a évalué l'efficacité du programme CHoBI7 pour augmenter le lavage des mains au savon dans les établissements de santé. MÉTHODES: Un essai contrôlé randomisé du programme CHoBI7 a été mené auprès de 404 patients atteints de diarrhée et des membres de leur famille qui les accompagnent dans des établissements de santé à Dhaka, au Bangladesh. Le bras "Message standard" a reçu le message standard donné au Bangladesh aux patients atteints de diarrhée sur l'utilisation de la solution de réhydratation orale. Le bras "Visite de l'établissement de santé + eau savonneuse" a reçu le message standard, le module de communication CHoBI7 a été délivré au chevet du patient et une bouteille d'eau savonneuse dans l'établissement de santé. Le bras "Visite de l'établissement de santé + station de lavage des mains" a reçu la même intervention, ainsi qu'une petite station de lavage des mains en plastique. Dans les 24 heures suivant l'intervention, une observation structurée de trois heures des pratiques de lavage des mains lors d'événements liés aux selles/vomis et à la nourriture (événements clés) a été menée dans les établissements de santé. RÉSULTATS: Par rapport au bras 'Message standard', le lavage des mains au savon était significativement plus fréquent lors des événements clés dans le bras 'Visite de l'établissement de santé + Station de lavage des mains' (58% contre 25%) (rapport de cotes (OR): 4,12 ; (intervalle de confiance (IC) de 95%: 1,86-9,14) et dans le bras 'Visite de l'établissement de santé + Eau savonneuse' (51% contre 25%) (OR: 3,02 ; (IC95% : 1,41-6,45). CONCLUSION: Ces résultats démontrent que l'implémentation du module CHoBI7 constitue une approche prometteuse pour augmenter le lavage des mains au savon dans un établissement de santé au Bangladesh.

Diarrhoeal children with concurrent severe wasting and stunting compared to severe wasting or severe stunting.

OBJECTIVE: Children with both severe wasting and severe stunting (SWSS) represent an extreme form of malnutrition and are prone to develop severe infection. The study aims to demonstrate clinical features and aetiology of diarrhoea among children with SWSS compared to those with either severe wasting (SW) or severe stunting (SS), which may help in early identification of high-risk children. METHODS: Data were extracted from the database of the diarrhoeal disease surveillance system (DDSS) of Dhaka Hospital, icddr,b from 2008 to 2017. Among 14 403 under-five diarrhoeal children, 149 had concurrent SWSS (WLZ/WHZ ˂-3 with LAZ/HAZ ˂-3), 795 had SW (WLZ/WHZ ˂-3 but LAZ/HAZ ≥-3) alone, and 1000 had only SS (LAZ/HAZ ˂-3 but WLZ/WHZ ≥-3). RESULTS: In logistic regression analysis after adjusting for potential confounders, dehydrating diarrhoea and slum dwelling were independently associated with SWSS vs. SW (P < 0.05). When compared with SS, dehydration and maternal illiteracy were independently associated with SWSS (P < 0.05). In comparison with SW or SS, SWSS less often included infection with rotavirus (P < 0.05). Dehydration was independently associated with SW vs. SS after adjusting for potential confounders (P < 0.05). CONCLUSION: Children with SWSS more often presented with dehydrating diarrhoea (69%) than children who had either SW (55%) or SS (43%). However, SWSS patients less frequently presented with rotavirus-associated diarrhoeal illnesses. This result underscores the importance of early detection and prompt management of dehydrating diarrhoea in children with concomitant severe wasting and severe stunting to reduce morbidity and mortality in these children, especially in poor settings.

OBJECTIF: Les enfants souffrant à la fois d'émaciation sévère et de retard de croissance sévère (ESRCS) représentent une forme extrême de malnutrition et sont susceptibles de développer des infections graves. L'étude vise à démontrer les caractéristiques cliniques et l'étiologie de la diarrhée chez les enfants atteints d'ESRCS par rapport à ceux souffrant d'émaciation sévère ou de retard de croissance sévère, ce qui pourrait aider à identifier rapidement les enfants à haut risque. MÉTHODES: Les données ont été extraites de la base de données du système de surveillance des maladies diarrhéiques (SSMD) de l'hôpital de Dhaka, icddr,b de 2008 à 2017. Parmi les 14.403 enfants de moins de cinq ans atteints de diarrhée, 149 avaient une ESRCS concomitants (WLZ/WHZ ˂-3 avec LAZ/HAZ ˂-3), 795 avaient une ES seule (WLZ/WHZ ˂-3 mais LAZ/HAZ ≥-3) et 1000 avaient un RCS seul (LAZ/HAZ ˂-3 mais WLZ/WHZ ≥-3). RÉSULTATS: Dans l'analyse de régression logistique, après ajustement des facteurs de confusion potentiels, la diarrhée déshydratante et l'habitation dans les bidonvilles étaient associées indépendamment à l'ESRCS par rapport à l'ES (P < 0,05). Par rapport au RCS, la déshydratation et l'analphabétisme de la mère ont été associés indépendamment à l'ESRCS (P < 0,05). Par rapport à l'ES ou au RCS, l'ESRCS incluait moins souvent l'infection par un rotavirus (P < 0,05). La déshydratation a été associée indépendamment à l'ES comparé au RCS après ajustement pour les facteurs de confusion potentiels (P < 0,05). CONCLUSION: Les enfants ayant une ESRCS présentent plus souvent une diarrhée déshydratante (69%) que ceux ayant soit une ES (55%) ou un RCS (43%). Cependant, les enfants atteints d'ESRCS présentaient moins fréquemment des maladies diarrhéiques associées à un rotavirus. Ce résultat souligne l'importance d'une détection précoce et d'une prise en charge rapide de la diarrhée déshydratante chez les enfants présentant une émaciation et un retard de croissance sévères concomitants, afin de réduire la morbidité et la mortalité chez ces enfants, en particulier dans les milieux pauvres.

Protection of staff and families during COVID-19 pandemic: experience from a research institute in Bangladesh.

International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), which contains the world's largest diarrheal disease hospital, established a service centre, including testing facilities, isolation unit, out-patient department, in-patient ward, and intensive care unit during COVID-19 pandemic. When the management of COVID-19 was challenging nationwide, icddr,b established this facility with the goal to provide COVID-related services to the staff and their relatives amidst the pandemic. Data related to this analysis were collected from April 2020 to December 2021. 1399 patients received treatment under this facility. Among them, 351 patients were treated at the out-patient facility, 98 at the isolation, and 197 at the in-patient ward. Among the admitted patients, survival was 86.29% (n = 170/197). Among the suspected patients, 17% (n = 103/606) were COVID-positive. Setting up an immediate COVID-19 management facility during the pandemic was challenging. It can be an example of how an organisation can adapt to any emergency and act accordingly.

Are young and older children with diarrhea presenting in the same way?

BACKGROUND: Diarrhoea is a global health problem. More than a quarter of diarrhoeal deaths occur among children less than five years. Different literatures analyzed presentation and outcomes of less than five diarrhoeal children. The world has made remarkable progress in reducing child mortality. So, older children are growing in number. Our aim was to identify clinical differentials and variations of pathogens among younger (less than five) and older (five to nine years) diarrhoeal children. METHOD: Data were extracted from the diarrhoeal disease surveillance system (DDSS) of Dhaka Hospital (urban site) and Matlab Hospital (rural site) of the International Centre for Diarrhoeal Disease Research, Bangladesh for the period of January 2012 to December 2021. Out of 28,781 and 12,499 surveillance patients in Dhaka and Matlab Hospital, 614 (2.13%) and 278 (2.22%) children were five to nine-years of age, respectively. Among under five children, 2456 from Dhaka hospital and 1112 from Matlab hospital were selected randomly for analysis (four times of five to nine years age children, 1:4). RESULTS: Vomiting, abdominal pain, and dehydrating diarrhoea were significantly higher in older children in comparison to children of less than five years age (p-value <0.05) after adjusting study site, gender, antibiotic use before hospitalization, diarrhoeal duration < 24 hours, intake of oral rehydration fluid at home, parental education, WASH practice and history of cough. Vibrio. cholerae, Salmonella, and Shigella were the common fecal pathogen observed among older children compared to under five after adjusting for age, gender and study site. CONCLUSION: Although percentage of admitted diarrhoeal children with five to nine years is less than under five years children but they presented with critical illness with different diarrhoeal pathogens. These observations may help clinicians to formulate better case management strategies for children of five to nine years that may reduce morbidity.

Comparison of Characteristics of Children with Severe Acute and Chronic Malnutrition Hospitalized with Diarrhea.

Children with malnutrition present with aberrant laboratory parameters. This study aimed to identify high-risk diarrheal children with varied nutritional status. The data were obtained from the electronic database of Dhaka Hospital, International Centre for Diarrhoeal Disease Research, Bangladesh from 2019 to 2021. Among 1,068 children under 5 years of age with diarrhea, 177 (14%) had severe acute malnutrition (SAM; weight-for-length/height Z score < -3), 239 children (17%) had severe stunting (SS; length/height-for-age Z score < -3), and 652 did not have malnutrition (weight-for-length/height and weight-for-age and length/height-for-age Z score > -2). We independently assessed the relationship of nutritional profiles with each clinical and laboratory parameter. After adjustment for age and sex in the multiple regression model, hyponatremia (adjusted odds ratio [aOR] = 2.37 [95% CI: 1.52-3.68]; P < 0.001) and dehydration (aOR = 2.42 [95% CI: 1.67-3.52]; P < 0.001) were independently associated with SAM compared with children without malnutrition. In comparison to non-malnutrition, SS was less likely to be associated with acute watery diarrhea (aOR = 0.66 [95% CI: 0.47-0.92]; P = 0.014) but was significantly associated with anemia (aOR = 2.18 [95% CI: 1.57-3.02]; P < 0.001) and thrombocytosis (aOR = 2.43 [95% CI: 1.78-3.32]; P < 0.001). The presence of hypernatremia was substantially lower in children with SAM (aOR = 0.38 [95% CI: 0.22-0.65]; P < 0.001) or SS (aOR = 0.56 [95% CI: 0.35-0.88]; P = 0.012) than in children without malnutrition. Severe stunting was less likely to be associated with dehydration (aOR = 0.44 [95% CI: 0.29-0.67]; P < 0.001) in contrast to SAM. Therefore, children hospitalized with diarrhea may have different clinical and laboratory manifestations depending on their nutritional status and may require differential treatment.

Impact of Rotaviral Diarrhea on Child Growth in Sub-Saharan Africa and South Asia in the Global Enteric Multicenter Study.

Rotavirus is the leading cause of dehydrating diarrhea among children in developing countries. The impact of rotaviral diarrhea on nutritional status is not well understood. We aimed to determine the association between rotavirus-positive moderate-to-severe diarrhea and nutrition in children under 5 years of age. We analyzed data from the Global Enteric Multicenter Study on children 0-59 months old from South Asia and sub-Saharan Africa. The relationships between explanatory variables and outcome variables were assessed using multiple linear regression; the explanatory variable was the presence of rotavirus in the stool sample, and the outcome variables were z scores [length/height-for-age (LAZ/HAZ), weight-for-age (WAZ), and weight-for-length/height (WLZ/WHZ)] at follow-up (∼60 days). The prevalence of rotaviral diarrhea was 17.3% (905/5,219) in South Asia and 19.95% (842/4,220) in sub-Saharan Africa. Rotavirus was associated with higher LAZ/HAZ (ß: 0.19; 95% CI: 0.12, 0.26; P <0.001) and WAZ (ß: 0.15; 95% CI: 0.79, 0.22; P <0.001) in sub-Saharan Africa and with lower WLZ/WHZ (ß coefficient: -0.08; 95% CI: -0.15, -0.009; P = 0.027) in South Asia. Our study indicates that rotaviral diarrhea is positively associated with nutritional status in sub-Saharan Africa and is negatively associated with nutritional status in South Asia. An expedited implementation policy of ongoing preventive and control strategies, including vaccination against rotavirus, is necessary to reduce the burden of rotaviral diarrhea, which may further help to reduce the potential nutritional ramifications.

Performance of chest X-ray scoring in predicting disease severity and outcomes of patients hospitalised with COVID-19 in Bangladesh.

Introduction: Evaluation of potential outcomes of COVID-19-affected pneumonia patients using computed tomography scans may not be conceivable in low-resource settings. Thus, we aimed to evaluate the performance of chest X-ray scoring in predicting the disease severity and outcomes of adults hospitalised with COVID-19. Methods: This was a retrospective chart analysis consuming data from COVID-19-positive adults who had chest X-ray availability and were admitted to a temporary COVID unit, in Bangladesh from 23rd April 2020 to 15th November 2021. At least one clinical intensivist and one radiologist combinedly reviewed each admission chest X-ray for the different lung findings. Chest X-ray scoring varied from 0 to 8, depending on the area of lung involvement with 0 indicating no involvement and 8 indicating ⩾75% involvement of both lungs. The receiver operating characteristic curve was used to determine the optimum chest X-ray cut-off score for predicting the fatal outcomes. Result: A total of 218 (82.9%) out of 263 COVID-19-affected adults were included in the study. The receiver operating characteristic curve demonstrated the optimum cut-off as ⩾3 and ⩾5 for disease severity and death, respectively. In multivariate logistic regression analysis, a chest X-ray score of ⩾3 was found to be independently associated with disease severity (aOR: 8.70; 95% CI: 3.82, 19.58, p < 0.001) and a score of ⩾5 with death (aOR: 16.53; 95% CI: 4.74, 57.60, p < 0.001) after adjusting age, sex, antibiotic usage before admission, history of fever, cough, diabetes mellitus, hypertension, total leukocytes count and C-reactive protein. Conclusion: Using chest X-ray scoring derived cut-off at admission might help to identify the COVID-19-affected adults who are at risk of severe disease and mortality. This may help to initiate early and aggressive management of such patients, thereby reducing their fatal outcomes.

Nutritional Profiles and Zinc Supplementation among Children with Diarrhea in Bangladesh.

Zinc supplementation is an added intervention with oral rehydration solution (ORS) for treating childhood diarrhea as per World Health Organization recommendations. Our study aimed to determine the prevalence of zinc administration in addition to ORS for childhood diarrhea before hospitalization and the nutritional profile of those children admitted to the outpatient department of the largest diarrheal facility in Bangladesh. This study used a screening dataset of a clinical trial (www.clinicaltrials.gov; NCT04039828) on zinc supplementation at a Dhaka hospital (International Centre for Diarrhoeal Disease Research, Bangladesh) between September 2019 and March 2020. A total of 1,399 children aged 3-59 months were included in our study. Children were divided into two groups (one group received zinc and another did not) and were analyzed accordingly; 39.24% (n = 549) children received zinc along with ORS for the current diarrheal episode prior to hospitalization. Percentages of underweight (weight-for-age z-score < -2 SD), stunting (length/height-for-age z-score < -2 SD), wasting (weight-for-length/height z-score < -2 SD), and overweight (weight-for-age z-score > +2 SD) among these children were 13.87% (n = 194), 14.22% (n = 199), 12.08% (n = 169), and 3.43% (n = 48), respectively. In logistic regression after adjusting age, sex, and nutritional status (underweight, stunting, wasting, and overweight), association of dehydration (adjusted odds ratio [aOR]: 0.06; 95% CI: 0.03-0.11; P < 0.01), bloody diarrhea (aOR: 0.18; 95% CI: 0.11-0.92; P < 0.01), and fever (aOR: 0.27; 95% CI: 0.18-0.41; P < 0.01) were less with children who received zinc at home. Bangladesh is one of the leading zinc coverage areas globally but lags behind the target for zinc coverage in diarrheal illness among under-five children. Policymakers should scale up and formulate guidelines with sustainable strategies to encourage zinc supplementation in diarrheal episodes in Bangladesh and elsewhere.

Inpatient Morbidity and Mortality of Severely Underweight Children Was Comparable to That of Severely Wasted Children in Dhaka, Bangladesh.

Both wasting and undernutrition are responsible for multiple morbidities and increased mortality in younger children hospitalized for acute illnesses. The question of whether children who are suffering from severe underweight are as vulnerable as children suffering from severe wasting needs to be researched further. We aimed to compare the morbidity and mortality of severely underweight but not severely wasted (SU-nSW) children with that of severely wasted (SW) children admitted to inpatient wards of a hospital. Data from 12,894 children aged < 5 years were collected using cross-sectional methods from Dhaka Hospital, International Centre for Diarrhoeal Disease Research, Bangladesh between March 2019 and December 2021. After exclusion of non-desired populations (N = 8,834), comparisons between SU-nSW (N = 1,876) and SW (N = 2,184) children were observed. The risk of morbidities and mortality among SU-nSW and SW children was analyzed after adjusting for age and sex. Inpatient morbidities were mostly similar among children with sepsis (adjusted odds ratio [aOR]: 0.90; 95% CI: 0.69, 1.19; P = 0.472) and convulsions (aOR: 0.84; 95% CI: 0.51, 1.37; P = 0.475). Dehydration (aOR: 0.71; 95% CI: 0.62, 0.81; P < 0.001) and hypokalemia (aOR: 0.58; 95% CI: 0.42, 0.79; P = 0.001) were more likely associated with SW children than with SU-nSW children. Pneumonia/severe pneumonia was more likely to affect SU-nSW children (aOR: 1.24; 95% CI: 1.02, 1.48; P = 0.018). Death was comparable between the two groups (aOR: 1.32; 95% CI: 0.70, 2.49; P = 0.386). This study underscores the importance of implementing present treatment guidelines for severe acute malnutrition in the facility-based management of severely underweight children as well.

Effects of probiotic and synbiotic supplementation on ponderal and linear growth in severely malnourished young infants in a randomized clinical trial.

Severe acute malnutrition (SAM) is a major global public health problem. We aimed to assess the effects of probiotic and synbiotic supplementation on rate of weight gain and change in length in young SAM infants. This study was substudy of a single-blind randomized clinical trial (NCT0366657). During nutritional rehabilitation, 67 <6 months old SAM infants were enrolled and randomized to receive either probiotic (Bifidobacterium. infantis EVC001) or synbiotic (B. infantis EVC001 + Lacto-N-neotetraose [LNnT]) or placebo (Lactose) for four weeks and were followed for four more weeks after supplementation. In multivariable linear regression model, the mean rate of weight gain in the probiotic arm compared to placebo was higher by 2.03 unit (P < 0.001), and 1.13 unit (P = 0.030) in the synbiotic arm. In linear mixed-effects model, mean WAZ was higher by 0.57 unit (P = 0.018) in probiotic arm compared to placebo. Although not statistically significant, delta length for age z score (LAZ) trended to be higher among children in probiotc (ß = 0.25) and synbiotic (ß = 0.26) arms compared to placebo in multivariable linear regression model. Our study describes that young SAM infants had a higher rate of weight gain when supplemented with probiotic alone, compared to their counterparts with either synbiotic or placebo.

Burden, predictors, and outcome of unconsciousness among under-five children hospitalized for community-acquired pneumonia: A retrospective study from a developing country.

Despite the reduction of death from pneumonia over recent years, pneumonia has still been the leading infectious cause of death in under-five children for the last several decades. Unconsciousness is a critical condition in any child resulting from any illness. Once it occurs during a pneumonia episode, the outcome is perceived to be fatal. However, data on children under five with pneumonia having unconsciousness are scarce. We've retrospectively analyzed the data of under-five children admitted at the in-patient ward of Dhaka Hospital of icddr,b during 1 January 2014 and 31 December 2017 with World Health Organization classified pneumonia or severe pneumonia. Children presented with or without unconsciousness were considered as cases and controls respectively. Among a total of 3,876 children fulfilling the inclusion criteria, 325 and 3,551 were the cases and the controls respectively. A multivariable logistic regression analysis revealed older children (8 months vs. 7.9 months) (adjusted odds ratio, aOR 1.02, 95% CI: 1.004-1.04, p = 0.015), hypoxemia (aOR 3.22, 95% CI: 2.39-4.34, p<0.001), severe sepsis (aOR 4.46, 95% CI: 3.28-6.06, p<0.001), convulsion (aOR 8.90, 95% CI: 6.72-11.79, p<0.001), and dehydration (aOR 2.08, 95% CI: 1.56-2.76, p<0.001) were found to be independently associated with the cases. The cases more often had a fatal outcome than the controls (23% vs. 3%, OR 9.56, 95% CI: 6.95-13.19, p<0.001). If the simple predicting factors of unconsciousness in children under five hospitalized for pneumonia with different severity can be initially identified and adequately treated with prompt response, pneumonia-related deaths can be reduced more effectively, especially in resource-limited settings.

Vibrio cholerae in rural and urban Bangladesh, findings from hospital-based surveillance, 2000-2021.

With more than 100,000 cases estimated each year, Bangladesh is one of the countries with the highest number of people at risk for cholera. Moreover, Bangladesh is formulating a countrywide cholera-control plan to satisfy the GTFCC (The Global Task Force on Cholera Control) Roadmap's goals. With a particular focus on cholera trends, variance in baseline and clinical characteristics of cholera cases, and trends in antibiotic susceptibility among clinical isolates of Vibrio cholerae, we used data from facility-based surveillance systems from icddr,b's Dhaka, and Matlab Hospitals from years 2000 to 2021. Female patients comprised 3,553 (43%) in urban and 1,099 (51.6%) in rural sites. Of the cases and most patients 5,236 (63.7%) in urban and 1,208 (56.7%) in the rural site were aged 15 years and more. More than 50% of the families belonged to the poor and lower-middle-class; in 2009 (24.4%) were in urban and in 1,791 (84.2%) were in rural sites. In the urban site, 2,446 (30%) of households used untreated drinking water, and 702 (9%) of families disposed of waste in their courtyard. In the multiple logistic regression analysis, the risk of cholera has significantly increased due to waste disposal in the courtyard and the boiling of water has a protective effect against cholera. Rotavirus (9.7%) was the most prevalent co-pathogen among the under-5 children in both sites. In urban sites, the percentage of V. cholerae along with co-existing ETEC and Campylobacter is changing in the last 20 years; Campylobacter (8.36%) and Enterotoxigenic Escherichia coli (ETEC) (7.15%) were the second and third most prevalent co-pathogens. Shigella (1.64%) was the second most common co-pathogen in the rural site. Azithromycin susceptibility increased slowly from 265 (8%) in 2006-2010 to 1485 (47.8%) in 2016-2021, and erythromycin susceptibility dropped substantially over 20 years period from 2,155 (98.4%) to 21 (0.9%). Tetracycline susceptibility decreased in the urban site from 2051 (45.9%) to 186 (4.2%) and ciprofloxacin susceptibility decreased from 2,581 (31.6%) to 1,360 (16.6%) until 2015, then increased 1,009 (22.6%) and 1,490 (18.2%) in 2016-2021, respectively. Since 2016, doxycycline showed 902 (100%) susceptibility. Clinicians need access to up-to-date information on antimicrobial susceptibility for treating hospitalized patients. To achieve the WHO-backed objective of eliminating cholera by 2030, the health systems need to be put under a proper surveillance system that may help to improve water and sanitation practices and deploy oral cholera vaccines strategically.

Vaccination following the expanded programme on immunization schedule could help to reduce deaths in children under five hospitalized for pneumonia and severe pneumonia in a developing country.

Background: Worldwide, pneumonia is the leading cause of mortality in children under the age of five. An expanded program on immunization (EPI) is one kind of evidence-based tool for controlling and even eradicating infectious diseases. Objectives: This study aimed to explore the impact of EPI vaccination, including BCG, DPT-Hib-Hep B, OPV, IPV, and PCV-10, among children from the age of 4 to 59 months hospitalized for pneumonia and severe pneumonia. Additionally, we evaluated the role of 10 valent pneumococcal conjugate vaccines alone on clinical outcomes in such children. Methods: In this retrospective chart review, children from the age of 4 to 59 months with WHO-defined pneumonia and severe pneumonia admitted to the Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b) between August 2013 and December 2017 who had the information on immunization as per EPI schedule by 4 months of age were included in the analysis. A comparison was made between the children who were fully immunized (immunization with BCG, DPT-Hib-Hep B, OPV, and IPV from 2013 to 2015 and PCV-10 from 2015 to 2017) and who were not immunized (consisting of partial immunization and no immunization) during the study period. Results: A total of 4,625 children had pneumonia and severe pneumonia during the study period. Among them, 2,605 (56.3%) had received the information on immunization; 2,195 (84.3%) were fully immunized by 4 months of age according to the EPI schedule and 410 were not immunized. In the log-linear binomial regression analysis, immunization of children from 4 to 59 months of age was found to be associated with a lower risk of diarrhea (p = 0.033), severe pneumonia (p = 0.001), anemia (p = 0.026), and deaths (p = 0.035). Importantly, the risk of developing severe pneumonia (1054/1,570 [67%] vs. 202/257 [79%], p < 0.001) and case-fatality rate (57/1,570 [3.6%] vs. 19/257 [7.4%], p = 0.005) was still significantly lower among those who were immunized with PCV-10 than those who were not. Conclusion: Children immunized as per the EPI schedule were at a lower risk of diarrhea, severe pneumonia, anemia, and death, compared to unvaccinated children. In addition, PCV-10 was found to be protective against severe pneumonia and deaths in vaccinated children. The overall results underscored the importance of the continuation of immunization, scrupulously adhering to the EPI schedule to reduce the risk of morbidities and mortalities in children, especially in resource-limited settings.

Evaluation of feasibility phase of adaptive version of locally made bubble continuous positive airway pressure oxygen therapy for the treatment of COVID-19 positive and negative adults with severe pneumonia and hypoxaemia.

Background: Bubble continuous positive airway pressure (bCPAP) oxygen therapy has been shown to be safe and effective in treating children with severe pneumonia and hypoxaemia in Bangladesh. Due to lack of adequate non-invasive ventilatory support during coronavirus disease 2019 (COVID-19) crisis, we aimed to evaluate whether bCPAP was safe and feasible when adapted for use in adults with similar indications. Methods: Adults (18-64 years) with severe pneumonia and moderate hypoxaemia (80 to <90% oxygen saturation (SpO2) in room air) were provided bCPAP via nasal cannula at a flow rate of 10 litres per minute (l/min) oxygen at 10 centimetres (cm) H2O pressure, in two tertiary hospitals in Dhaka, Bangladesh. Qualitative interviews and focus group discussions, using a descriptive phenomenological approach, were performed with patients and staff (n = 39) prior to and after the introduction (n = 12 and n = 27 respectively) to understand the operational challenges to the introduction of bCPAP. Results: We enrolled 30 adults (median age 52, interquartile range (IQR) 40-60 years) with severe pneumonia and hypoxaemia and/or acute respiratory distress syndrome (ARDS) irrespective of coronavirus disease 2019 (COVID-19) test results to receive bCPAP. At baseline mean SpO2 on room air was 87% (±2) which increased to 98% (±2), after initiation of bCPAP. The mean duration of bCPAP oxygen therapy was 14.4 ± 24.8 hours. There were no adverse events of note, and no treatment failure or deaths. Operational challenges to the clinical introduction of bCPAP were lack of functioning pulse oximeters, difficult nasal interface fixation among those wearing nose pin, occasional auto bubbling or lack of bubbling in water-filled plastic bottle, lack of holder for water-filled plastic bottle, rapid turnover of trained clinicians at the hospitals, and limited routine care of patients by hospital clinicians particularly after official hours. Discussion: If the tertiary hospitals in Bangladesh are supplied with well-functioning good quality pulse oximeters and enhanced training of the doctors and nurses on proper use of adapted version of bCPAP, in treating adults with severe pneumonia and hypoxaemia with or without ARDS, the bCPAP was found to be safe, well tolerated and not associated with treatment failure across all study participants. These observations increase the confidence level of the investigators to consider a future efficacy trial of adaptive bCPAP oxygen therapy compared to WHO standard low flow oxygen therapy in such patients. Conclusion: s Although bCPAP oxygen therapy was found to be safe and feasible in this pilot study, several challenges were identified that need to be taken into account when planning a definitive clinical trial.

Risk Factors for Enterotoxigenic Bacteroides fragilis Infection and Association with Environmental Enteric Dysfunction and Linear Growth in Children: Results from the MAL-ED Study.

Despite reports of enterotoxigenic Bacteroides fragilis (ETBF) isolation from asymptomatic children, no reports exist regarding the possible association of ETBF with long-term complications such as development of environmental enteric dysfunction (EED) and subsequent linear growth faltering in childhood. We aimed to establish a potential association between the burden of asymptomatic ETBF infection and EED and linear growth at 24 months of age using the data collected from 1,715 children enrolled in the multi-country birth cohort study, known as the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health study. Using Poisson regression models, we evaluated the site-specific incidence rate and, subsequently, identified the risk factors and assessed the association between the burden of ETBF infection and EED score and linear growth at 24 months of age. The overall incidence rate of ETBF infections per 100 child-months across all study sites was 10.6%, with the highest and lowest incidence of ETBF infections being reported in Tanzania (19.6%) and Peru (3.6%), respectively. Female gender, longer duration of breastfeeding, and improved water access, sanitation, and hygiene practices, such as improved drinking water source, improved sanitation, and improved floor material in households, along with enhanced maternal education and less crowding in the households were found to be protective against incidences of ETBF infection. The burden of ETBF infections was found to have significant associations with EED and linear growth faltering at 24 months of age across all the study sites. Our findings warrant regular clinical monitoring to reduce the burden of ETBF infections and diminish the burden of enteropathy and linear growth faltering in childhood.

Association of human milk oligosaccharides and nutritional status of young infants among Bangladeshi mother-infant dyads.

Human milk oligosaccharides (HMOs) support the development of a healthy gut microbiome and the growth of infants. We aimed to determine the association of different HMOs with severe acute malnutrition (SAM) among Bangladeshi young infants. This study was nested within a single-blind, randomized, pilot clinical trial (NCT0366657). A total of 45 breastmilk samples from mothers of < 6 months old infants who had SAM (n = 26) or were non-malnourished (n = 19) and were analyzed for constituent HMOs. Of the infants with SAM, 14 (53.85%) had secretor mothers, and 11 (57.89%) of the non-malnourished infants had secretor mothers. A one-unit increase in the relative abundance of sialylated HMOs was associated with higher odds of SAM in age and sex adjusted model (aOR = 2.00, 90% CI 1.30, 3.06), in age, sex, and secretor status adjusted model (aOR = 1.96, 90% CI 1.29, 2.98), and also in age and sex adjusted model among non-secretor mothers (aOR = 2.86, 90% CI 1.07, 7.62). In adjusted models, there was no evidence of a statistically significant association between SAM and fucosylated or undecorated HMOs. Our study demonstrates that a higher relative abundance of sialylated HMOs in mothers' breastmilk may have a negative impact on young infants' nutritional status.
