Severe Sepsis in Severely Malnourished Young Bangladeshi Children with Pneumonia: A Retrospective Case Control Study

Stakeholder engagement to introduce a standardised register for improved inpatient care of newborns and sick children in Bangladesh

Background

Despite a global decrease of 59% in under-five mortality rates from 1990 to 2021, child survival remains a pressing issue. This holds true for Bangladesh, as well. In response, the Government of Bangladesh introduced a standardised register for strengthening the inpatient management of newborns and sick children in 2021.

Methods

We employed a comprehensive four-phase stakeholder engagement process to implement an inpatient register for newborns and sick children. The first stage included identifying and prioritising potential stakeholders at the national and district levels. We identified eight organisations involved in newborn and child health and selected 24 participants from various other sectors for workshops aimed at raising awareness about the register's introduction. These stakeholders also participated in the register's design, development strategies planning, and implementation phases. These phases were led by the 'National Newborn Health and IMCI programme' with support from various partners. A technical working group reviewed existing registers and helped prepare training materials. Feedback from each workshop was crucial in finalising the register.

Results

The Government of Bangladesh has recognised the need for an indoor register for newborns and sick children, which was to be established in collaboration with development partners. This initiative can enhance the quality of care for sick children and increase service provider accountability. Due to its successful implementation, it will continue to be used in the Kushtia and Dinajpur districts, with plans for a nationwide scale-up. The Government has allocated funds in the next health sector programme for orientation and register printing. A strengths, weaknesses, opportunities, and threats (SWOT) analysis of the stakeholder engagement process highlighted strengths such as a context-specific approach and collaborative engagement, as well as challenges such as time resource requirements.

Conclusions

Implementing an inpatient register for newborns and sick children through stakeholder engagement can effectively improve child health care services. Aside from challenges such as resource intensiveness and stakeholder commitments, success depended on the organising authority's expertise in relationship building, budget allocation, time management, and workforce dedication. Therefore, strategic planning, staff recruitment, networking, and budgeting are crucial for successful stakeholder engagement and health care initiatives.

Prevalence and predictors of magnesium imbalance among critically ill diarrheal children and their outcome in a developing country

Despite having essential roles in maintaining human body physiology, magnesium has gained little attention. We sought to evaluate the prevalence and predictors of magnesium imbalance in diarrheal children admitted to an intensive care unit. This retrospective data analysis was conducted among children admitted between January 2019 and December 2019. Eligible children were categorized by serum magnesium levels that were extracted from the hospital database. Among 557 participants, 29 (5.2%) had hypomagnesemia, 344 (61.8%) had normomagnesemia and 184 (33.0%) had hypermagnesemia. By multivariable multinomial logistic regression, we have identified older children (adjusted multinomial odds ratio, mOR 1.01, 95% CI: 1.004-1.018, p = 0.002) as a predictor of hypomagnesemia. Conversely, younger children (adjusted mOR 0.99, 95% CI: 0.982-0.998, p = 0.02), shorter duration of fever (adjusted mOR 0.92, 95% CI: 0.857-0.996, p = 0.04), convulsion (adjusted mOR 1.55, 95% CI: 1.005-2.380, p = 0.047), dehydration (adjusted mOR 3.27, 95% CI: 2.100-5.087, p<0.001), pneumonia (adjusted mOR 2.65, 95% CI: 1.660-4.240, p<0.001) and acute kidney injury (adjusted mOR 2.70, 95% CI: 1.735-4.200, p<0.001) as the independent predictors of hypermagnesemia. The mortality was higher among children with hypermagnesemia (adjusted mOR 2.31, 95% CI: 1.26-4.25, p = 0.007). Prompt identification and management of the magnesium imbalance among critically ill diarrheal children might have survival benefits, especially in resource-limited settings.

Effectiveness of the WHO Protocol for the Management of Shock in Children With Severe Acute Malnutrition

Background The WHO protocol for the management of shock in children with severe acute malnutrition (SAM) is not supported by physiological evidence. In this study, we aimed to assess the effectiveness of the WHO treatment protocol in the management of shock in children with SAM. Methodology This cohort study included children aged 2-60 months with WHO-defined SAM and fulfilling the WHO criteria for identification of shock. The exclusion criteria included severe anemia (hemoglobin <4 g/dL), congenital anomalies, congenital heart defects, and chronic diseases. The WHO treatment protocol for the management of shock was used, and features of resolution of shock were assessed at eight and 24 hours. Oliguria was recorded at eight and 24 hours along with in-hospital mortality. Multiple logistic regression was used to determine predictors of mortality. Results Of 53 children, 40 (75.4%) were discharged and 13 (24.5%) expired. We observed significant resolution of features of shock at 24 hours compared to eight hours (35 (71.4%) vs. 10 (18.8%), p < 0.0001). Further analysis revealed a significant resolution of features of shock (p = 0.03) at 24 hours in both fluid-responsive (24 vs. 10) and fluid-refractory children (11 vs. 27) compared to eight hours. Multivariate analysis revealed that mechanical ventilation was positively related to death (odds ratio (OR) = 85, 95% confidence interval (CI) = 8.49, 860, p < 0.0001), and inotrope scores <20 (OR = 0.053, 95% CI = 0.004, 0.64, p = 0.021) and blood transfusion (OR = 0.025, 95% CI = 0.001, 0.61, p = 0.024) had favorable outcomes. Conclusions The WHO protocol for the management of shock in children with SAM is effective in fluid-responsive shock whereas evidence was inconclusive in fluid-refractory shock.

Haemodynamic support for paediatric septic shock: a global perspective

Septic shock is a leading cause of hospitalisation, morbidity, and mortality for children worldwide. In 2020, the paediatric Surviving Sepsis Campaign (SSC) issued evidence-based recommendations for clinicians caring for children with septic shock and sepsis-associated organ dysfunction based on the evidence available at the time. There are now more trials from multiple settings, including low-income and middle-income countries (LMICs), addressing optimal fluid choice and amount, selection and timing of vasoactive infusions, and optimal monitoring and therapeutic endpoints. In response to developments in adult critical care to trial personalised haemodynamic management algorithms, it is timely to critically reassess the current state of applying SSC guidelines in LMIC settings. In this Viewpoint, we briefly outline the challenges to improve sepsis care in LMICs and then discuss three key concepts that are relevant to management of children with septic shock around the world, especially in LMICs. These concepts include uncertainties surrounding the early recognition of paediatric septic shock, choices for initial haemodynamic support, and titration of ongoing resuscitation to therapeutic endpoints. Specifically, given the evolving understanding of clinical phenotypes, we focus on the controversies surrounding the concepts of early fluid resuscitation and vasoactive agent use, including insights gained from experience in LMICs and high-income countries. We outline the key components of sepsis management that are both globally relevant and translatable to low-resource settings, with a view to open the conversation to the large variety of treatment pathways, especially in LMICs. We emphasise the role of simple and easily available monitoring tools to apply the SSC guidelines and to tailor individualised support to the patient's cardiovascular physiology.

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.

Efficacy of dopamine, epinephrine and blood transfusion for treatment of fluid refractory shock in children with severe acute malnutrition or severe underweight and cholera or other dehydrating diarrhoeas: protocol for a randomised controlled clinical trial

INTRODUCTION

Diarrhoea is one of the leading causes of under-5 childhood mortality and accounts for 8% of 5.4 million global under-5 deaths. In severely malnourished children, diarrhoea progresses to shock, where the risk of mortality is even higher. At icddr,b Dhaka Hospital, the fatality rate is as high as 69% in children with severe malnutrition and fluid refractory septic shock. To date, no study has evaluated systematically the effects of inotrope or vasopressor or blood transfusion in children with dehydrating diarrhoea (eg, in cholera) and severe acute malnutrition (SAM) or severe underweight who are in shock and unresponsive to WHO-recommended fluid therapy. To reduce the mortality of severely malnourished children presenting with diarrhoea and fluid refractory shock, we aim to compare the efficacy of blood transfusion, dopamine and epinephrine in fluid refractory shock in children who do not respond to WHO-recommended fluid resuscitation.

METHODS AND ANALYSIS

In this randomised, three-arm, controlled, non-masked clinical trial in children 1-59 months old with SAM or severe underweight and fluid refractory shock, we will compare the efficacy of dopamine or epinephrine administration versus blood transfusion in children who failed to respond to WHO-recommended fluid resuscitation. The primary outcome variable is the case fatality rate. The effect of the intervention will be assessed by performing an intention-to-treat analysis. Recruitment and data collection began in July 2021 and are now ongoing. Results are expected by May 2023.

ETHICS AND DISSEMINATION

This study has been approved by the icddr,b Institutional Review Board. We adhere to the 'Declaration of Helsinki' (2000), guidelines for Good Clinical Practice. Before enrolment, we collect signed informed consent from the parents or caregivers of the children. We will publish the results in a peer-reviewed journal and will arrange a dissemination seminar.

TRIAL REGISTRATION NUMBER

NCT04750070.

Reporting of Social Determinants of Health in Pediatric Sepsis Studies

OBJECTIVE

Standardized, consistent reporting of social determinants of health (SDOH) in studies on children with sepsis would allow for: 1) understanding the association of SDOH with illness severity and outcomes, 2) comparing populations and extrapolating study results, and 3) identification of potentially modifiable socioeconomic factors for policy makers. We, therefore, sought to determine how frequently data on SDOH were reported, which factors were collected and how these factors were defined in studies of sepsis in children.

DATA SOURCES AND SELECTION

We reviewed 106 articles (published between 2005 and 2020) utilized in a recent systematic review on physiologic criteria for pediatric sepsis.

DATA EXTRACTION

Data were extracted by two reviewers on variables that fell within the World Health Organization's SDOH categories.

DATA SYNTHESIS

SDOH were not the primary outcome in any of the included studies. Seventeen percent of articles (18/106) did not report on any SDOH, and a further 36.8% (39/106) only reported on gender/sex. Of the remaining 46.2% of articles, the most reported SDOH categories were preadmission nutritional status (35.8%, 38/106) and race/ethnicity (18.9%, 20/106). However, no two studies used the same definition of the variables reported within each of these categories. Six studies reported on socioeconomic status (3.8%, 6/106), including two from upper-middle-income and four from lower middle-income countries. Only three studies reported on parental education levels (2.8%, 3/106). No study reported on parental job security or structural conflict.

CONCLUSIONS

We found overall low reporting of SDOH and marked variability in categorizations and definitions of SDOH variables. Consistent and standardized reporting of SDOH in pediatric sepsis studies is needed to understand the role these factors play in the development and severity of sepsis, to compare and extrapolate study results between settings and to implement policies aimed at improving socioeconomic conditions related to sepsis.

Diagnostic, Management, and Research Considerations for Pediatric Acute Respiratory Distress Syndrome in Resource-Limited Settings: From the Second Pediatric Acute Lung Injury Consensus Conference

OBJECTIVES

Diagnosis of pediatric acute respiratory distress syndrome (PARDS) in resource-limited settings (RLS) is challenging and remains poorly described. We conducted a review of the literature to optimize recognition of PARDS in RLS and to provide recommendations/statements for clinical practice and future research in these settings as part of the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2).

DATA SOURCES

MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost).

STUDY SELECTION

We included studies related to precipitating factors for PARDS, mechanical ventilation (MV), pulmonary and nonpulmonary ancillary treatments, and long-term outcomes in children who survive PARDS in RLS.

DATA EXTRACTION

Title/abstract review, full-text review, and data extraction using a standardized data collection form.

DATA SYNTHESIS

The Grading of Recommendations Assessment, Development, and Evaluation approach was used to identify and summarize evidence and develop recommendations. Seventy-seven studies were identified for full-text extraction. We were unable to identify any literature on which to base recommendations. We gained consensus on six clinical statements (good practice, definition, and policy) and five research statements. Clinicians should be aware of diseases and comorbidities, uncommon in most high-income settings, that predispose to the development of PARDS in RLS. Because of difficulties in recognizing PARDS and to avoid underdiagnosis, the PALICC-2 possible PARDS definition allows exclusion of imaging criteria when all other criteria are met, including noninvasive metrics of hypoxemia. The availability of MV support, regular MV training and education, as well as accessibility and costs of pulmonary and nonpulmonary ancillary therapies are other concerns related to management of PARDS in RLS. Data on long-term outcomes and feasibility of follow-up in PARDS survivors from RLS are also lacking.

CONCLUSIONS

To date, PARDS remains poorly described in RLS. Clinicians working in these settings should be aware of common precipitating factors for PARDS in their patients. Future studies utilizing the PALICC-2 definitions are urgently needed to describe the epidemiology, management, and outcomes of PARDS in RLS.

Prevalence and outcome of anemia among children hospitalized for pneumonia and their risk of mortality in a developing country

Data are limited on the prevalence and outcome of anemia and its risk on mortality among children under five years of age hospitalized for pneumonia/severe pneumonia. Thus, we conducted a secondary analysis of data extracted from Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh to address the evidence gap. Among 3468 children fulfilling the study criteria,1712 (49.4%) had anemia. If children aged ≤ 1.0, > 1.0 to 2.0, > 2.0 to < 6.0, and ≥ 6.0 to 59 months had blood hemoglobin (Hb) value of ≤ 10.7 g/dL, ≤ 9.4 g/dL, ≤ 9.5 g/dL, and ≤ 11 g/dl respectively; we considered them anemic. The trend of prevalence of anemia was found to be inversely related to increasing age (Chi-square for linear trend analysis was done to understand the relation of anemia with increasing age, which was = 6.96; p = 0.008). During hospitalization anemic children more often developed respiratory failure (7.2% vs. 4.4%, p < 0.001) and fatal outcome (7.1.0% vs. 4.2%, p < 0.001) than the children who did not have anemia. After adjusting for potential confounders, such as female sex, lack of immunization, abnormal mental status, severe acute malnutrition, dehydration, hypoxemia, severe sepsis, and bacteremia using multivariable logistic regression analysis, anemia was found to be independently associated with fatal outcome (OR = 1.88, 95% CI 1.23–2.89, p = 0.004). Thus, future interventional studies on the early management of anemia may be warranted to understand whether the intervention reduces the morbidity and deaths in such children.

Physical Quality of Life of Sepsis Survivor Severely Malnourished Children after Hospital Discharge: Findings from a Retrospective Chart Analysis

Background: Quality of life (QoL) among pediatric sepsis survivors in resource-limited countries is poorly understood. We aimed to evaluate the QoL among sepsis survivors, by comparing them with non-sepsis survivors three months after hospital discharge. Methodology: In this retrospective chart analysis with a case–control design, we compared children having sepsis and non-sepsis at hospital admission and during their post-hospitalization life, where the study population was derived from a hospital cohort of 405 severely malnourished children having pneumonia. Results: The median age (months, inter-quartile range) of the children having sepsis and non-sepsis was 10 (5, 17) and 9 (5, 18), respectively. Approximately half of the children among the sepsis survivors had new episodes of respiratory symptoms at home. Though death was significantly higher (15.8% vs. 2.7%, p ≤ 0.001) at admission among the sepsis group, deaths during post-hospitalization life (7.8% vs. 8.8%, p = 0.878) were comparable. A verbal autopsy revealed that before death, most of the children from the sepsis group had respiratory complaints, whereas gastrointestinal complaints were more common among the non-sepsis group. Conclusions: Pediatric sepsis is life-threatening both during hospitalization and post-discharge. The QoL after sepsis is compromised, including re-hospitalization and the development of new episodes of respiratory symptoms especially before death.

Characteristics of severely malnourished under-five children immunized with Bacillus Calmette-Guérin following Expanded Programme on Immunization schedule and their outcomes during hospitalization at an urban diarrheal treatment centre, Bangladesh

Background

Bacillus Calmette-Guérin (BCG) vaccination has recently been found to have beneficial effects among children infected other than Mycobacterium tuberculosis. Due to the paucity of data on the outcomes of children who had successful BCG vaccination following Expanded Programme on Immunization (EPI) schedule, we aimed to investigate the characteristics of such children and their outcomes who were hospitalized for severe malnutrition.

Methods

A prospective observational study was conducted to determine the viral etiology of pneumonia in severely malnourished children those were admitted to the Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) between April 2015 and December 2017, constituted the study population. Using a case-control design for the analysis, children having BCG vaccination prior hospital admission were treated as cases (n = 611) and those without vaccination, constituted as controls (n = 83). Bi-variate analysis was conducted using socio-demographic, clinical, laboratory, and treatment characteristics on admission and outcomes during hospitalization. Finally, log-linear binomial regression analysis was done to identify independent impact of BCG vaccination.

Results

The cases more often presented with older age, have had lower proportion of maternal illiteracy, higher rate of breastfeeding, severe wasting and lower rate of hypoglycemia, compared to the controls. The cases were also found to have lower risk of severe sepsis and deaths, compared to the controls (for all, p<0.05). However, in log-linear binomial regression analysis, after adjusting for potential confounders, BCG vaccination following EPI schedule (RR:0.54; 95%CI = 0.33–0.89; p = 0.015) and breastfeeding (RR:0.53; 95%CI = 0.35–0.81; p = 0.003) were found to be protective for the development of severe sepsis.

Conclusion

BCG vaccination and breastfeeding were found to be protective for the development of severe sepsis in hospitalized severely malnourished under-five children which underscores the importance of continuation of BCG vaccination at birth and breastfeeding up to two years of age.

Criteria for Pediatric Sepsis-A Systematic Review and Meta-Analysis by the Pediatric Sepsis Definition Taskforce

OBJECTIVE

To determine the associations of demographic, clinical, laboratory, organ dysfunction, and illness severity variable values with: 1) sepsis, severe sepsis, or septic shock in children with infection and 2) multiple organ dysfunction or death in children with sepsis, severe sepsis, or septic shock.

DATA SOURCES

MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from January 1, 2004, and November 16, 2020.

STUDY SELECTION

Case-control studies, cohort studies, and randomized controlled trials in children greater than or equal to 37-week-old postconception to 18 years with suspected or confirmed infection, which included the terms "sepsis," "septicemia," or "septic shock" in the title or abstract.

DATA EXTRACTION

Study characteristics, patient demographics, clinical signs or interventions, laboratory values, organ dysfunction measures, and illness severity scores were extracted from eligible articles. Random-effects meta-analysis was performed.

DATA SYNTHESIS

One hundred and six studies met eligibility criteria of which 81 were included in the meta-analysis. Sixteen studies (9,629 patients) provided data for the sepsis, severe sepsis, or septic shock outcome and 71 studies (154,674 patients) for the mortality outcome. In children with infection, decreased level of consciousness and higher Pediatric Risk of Mortality scores were associated with sepsis/severe sepsis. In children with sepsis/severe sepsis/septic shock, chronic conditions, oncologic diagnosis, use of vasoactive/inotropic agents, mechanical ventilation, serum lactate, platelet count, fibrinogen, procalcitonin, multi-organ dysfunction syndrome, Pediatric Logistic Organ Dysfunction score, Pediatric Index of Mortality-3, and Pediatric Risk of Mortality score each demonstrated significant and consistent associations with mortality. Pooled mortality rates varied among high-, upper middle-, and lower middle-income countries for patients with sepsis, severe sepsis, and septic shock (p < 0.0001).

CONCLUSIONS

Strong associations of several markers of organ dysfunction with the outcomes of interest among infected and septic children support their inclusion in the data validation phase of the Pediatric Sepsis Definition Taskforce.

Prevalence, Predictive Factors, and Outcomes of Respiratory Failure in Children With Pneumonia Admitted in a Developing Country

BACKGROUND

Pneumonia has been the leading infectious cause of morbidity and mortality in children under 5 years of age for the last several decades. Although most of these deaths occur due to respiratory failure, published data are limited regarding predicting factors and outcomes of respiratory failure in children hospitalized with pneumonia or severe pneumonia.

OBJECTIVE

This study aimed to explore the prevalence, predicting factors, and outcomes of respiratory failure in children under-five with pneumonia or severe pneumonia.

METHODS

In this retrospective chart analysis, we enrolled children under 5 years of age hospitalized with pneumonia or severe pneumonia in the Dhaka Hospital of International Centre for Diarrheal Disease Research, Bangladesh (icddr,b) between August 2013 and December 2017. Comparisons were made between children with respiratory failure (n = 212) and those without respiratory failure (n = 4,412). Respiratory failure was defined when the oxygen saturation/fraction of inspired oxygen (SpO₂/FiO₂) was <315.

RESULTS

A total of 4,625 children with pneumonia or severe pneumonia were admitted during this study period. Among them, 212 (4.6%) children developed respiratory failure and formed the case group. A total of 4,412 (95.3%) children did not develop respiratory failure and formed the comparison group. In logistic regression analysis, after adjusting with potential confounders, severe sepsis [adjusted odds ratio (aOR): 12.68, 95% CI: 8.74-18.40], convulsion (aOR: 4.52, 95% CI: 3.06-6.68), anemia (aOR: 1.76, 95% CI: 1.20-2.57), and severe underweight (aOR: 1.97, 95% CI: 1.34-2.89) were found to be independently associated with respiratory failure. As expected, children with respiratory failure more often had fatal outcome than without respiratory failure (74, 1%, p < 0.001).

CONCLUSION

The results of our analyses revealed that prevalence of respiratory failure was 4.6% among under-five children hospitalized for pneumonia or severe pneumonia. Severe sepsis, convulsion, anemia, and severe underweight were the independent predictors for respiratory failure in such children and their case-fatality rate was significantly higher than those without respiratory failure. Early recognition of these predicting factors of respiratory failure may help clinicians imitating prompt treatment that may further help to reduce deaths in such children, especially in resource-limited settings.

Critical illness related to community acquired pneumonia, its epidemiology and outcomes in a pediatric intensive care unit of Pakistan

BACKGROUND

To determine the epidemiology and outcomes in critically ill children admitted with severe community acquired pneumonia (CAP) and to identify risk factors associated with mortality in a pediatric intensive care unit (PICU) METHODS: Retrospective review of medical records of all children (age 1 month to 18 years) admitted to PICU with CAP from January 2013 to March 2018 was done. Patients admitted in last 2 weeks before current illness and those with bronchiolitis (based on clinical diagnosis) were excluded. Data were collected on a structured proforma and included demographic, clinical data, comorbidities, therapeutic information, laboratory data, and outcome data. Results were presented as mean with SD and frequency with percentages. Factors associated with mortality were analyzed, using logistic regression for both univariate and multivariate analyses.

RESULTS

A total of 187 children with severe CAP were identified, 53.5% (n = 100) were <1 year of age and 65.2% (n = 122) were male, 32.6% (n = 61) were underweight, and 24.6% (n = 46) were stunted. A total of 94% (175) required mechanical ventilation. Mortality among the cohort was 20.3% (n = 38) with median length of mechanical ventilation 4 (2-8) days, and median length of PICU stay was 6 (4-12) days. PRISM score >10 on admission, presence of systemic illness, empyema, and length of PICU stay 14 (±2) days were associated with increased mortality among critically ill children admitted with CAP (p < .05).

CONCLUSIONS

Severe illness on presentation, presence of systemic illness and empyema are associated with increased mortality in children admitted to the PICU with severe CAP.

The Utility of Bedside Assessment Tools and Associated Factors to Avoid Antibiotic Overuse in an Urban PICU of a Diarrheal Disease Hospital in Bangladesh

BACKGROUND

Antibiotic exposure in the pediatric intensive care unit (PICU) is very high, although 50% of all antibiotics may be unnecessary. We aimed to determine the utility of simple bedside screening tools and predicting factors to avoid antibiotic overuse in the ICU among children with diarrhea and critical illness.

METHODS

We conducted a retrospective, single-center, case-control study that included children aged 2-59 months who were admitted to PICU with diarrhea and critical illness between 2017 and 2020.

RESULTS

We compared young children who did not receive antibiotics (cases, n = 164) during ICU stay to those treated with antibiotics (controls, n = 346). For predicting the 'no antibiotic approach', the sensitivity of a negative quick Sequential Organ Failure Assessment (qSOFA) was similar to quick Pediatric Logistic Organ Dysfunction-2 (qPELOD-2) and higher than Systemic Inflammatory Response Syndrome (SIRS). A negative qSOFA or qPELOD-2 score calculated during PICU admission is superior to SIRS to avoid antibiotic overuse in under-five children. The logistic regression analysis revealed that cases were more often older and independently associated with hypernatremia. Cases less often had severe underweight, altered mentation, age-specific fast breathing, lower chest wall in-drawing, adventitious sound on lung auscultation, abdominal distension, developmental delay, hyponatremia, hypocalcemia, and microscopic evidence of invasive diarrhea (for all, p < 0.05).

CONCLUSION

Antibiotic overuse could be evaded in PICU using simple bedside screening tools and clinical characteristics, particularly in poor resource settings among children with diarrhea.

Differences of TNF-α, IL-6 and Gal-3 in lobar pneumonia and bronchial pneumonia caused by mycoplasma pneumoniae

OBJECTIVE

To investigate the differences of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and galectin-3 concentrations in lobar pneumonia and bronchopneumonia induced by mycoplasma pneumoniae (MP) in children and to explore these related factors predicting the severity of MP.

METHODS

A total of 148 children with mycoplasma pneumoniae pneumonia (MPP) and 32 healthy controls were analyzed from March 2017 to August 2018 in our province. Clinical information was collected from the hospitalized MP patients. The 148 patients with MPP were divided into two groups: lobar pneumonia group and bronchial pneumonia group. The 32 healthy children were considered the control group. The concentrations of TNF-α, IL-6 and Gal-3 were examined in the serum of 148 children patients with MPP and 32 healthy children by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA).

RESULTS

The TNF-α, IL-6 and Gal-3 levels were obviously higher in both the lobar pneumonia and bronchial pneumonia groups, compared to those in the control group. Furthermore, these levels were significantly higher in the lobar pneumonia group, compared to the bronchial pneumonia group. After treatment, the levels of TNF-α, IL-6 and Gal-3 totally descended during the recovery period.

CONCLUSION

There are differences in serum TNF-α, IL-6 and Gal-3 concentrations in lobar pneumonia and bronchial pneumonia caused by MP in children. In general, the TNF-α, IL-6 and Gal-3 levels were significantly higher in the lobar pneumonia group, when compared to the bronchial pneumonia group. This was because most lobar pneumonia cases are much more serious than bronchial pneumonia. Moreover, it has been proven that TNF-α, IL-6 and Gal-3 may play an important role in the pathogenesis development of MPP. At the same time, these are important issues in diagnosing MPP.

Sensitivity Patterns of Bacterial Pathogens Isolated from Blood Cultures of Under-Five Children with Pneumonia and Clinical Sepsis

Treatment options for pneumonia and sepsis by antibiotics are limited due to the development of multidrug-resistant bacterial strains. This unmatched case-control study determined the antibiotic sensitivity against bacterial isolates obtained from septic and nonseptic children with pneumonia. Children of either sex aged 0–59 months with a history of cough or shortness of breath and radiologically confirmed pneumonia were enrolled in this study. Cases with clinical signs of sepsis at admission (n = 151) were compared to cases without sepsis as controls (n = 107). A total of 205 children had a performance of blood culture, with 123 children suffering from clinical sepsis. Blood cultures showed bacterial growth in 19% of the septic samples, with 8% coagulase-negative staphylococci and 2.4% Acinetobacter species. Only 1.6% of the cases were infected by Streptococcus pneumonia, Haemophilus influenzae, Salmonella typhi and Klebsiella. In contrast, children without sepsis presented positive blood cultures with growth of Salmonella typhi in 2.4% of the cases and growth of Klebsiella in 1.2%. Bacteria were sensitive to imipenem in 100% of the cases (86% for meropenem, 83% for ceftazidime and 76% for ciprofloxacin). The mortality rate was significantly higher in children with pneumonia complicated by sepsis (odds ratio (OR) = 3.02, 95% confidence interval (CI), 1.11–8.64, p < 0.027). Knowledge about specific laboratory characteristics in children with pneumonia will facilitate an early diagnosis and treatment of sepsis and reduce mortality.

Seizure in Children Under Five Presenting With Pneumonia in a Critical Care Ward in Bangladesh: Prevalence, Associated Factors, and Outcome

BACKGROUND

Pneumonia is the leading infectious cause of deaths in children under 5 for the last few decades. Development of seizure in those children is common and associated with increased risk of deaths. We therefore investigated the prevalence, associated factors and outcome of seizure in children hospitalized with pneumonia.

METHODS

We conducted a retrospective chart analysis in the intensive care unit of the Dhaka Hospital of icddr,b. Children under 5 with World Health Organization (WHO) classified clinical (excluding seizure as 1 of the clinical diagnostics) and radiologic pneumonia, admitted to the intensive care unit at Dhaka Hospital of icddr,b between August 2013 and December 2017 were analyzed. We initially identified the children with pneumonia who had seizure. For comparison, we have taken 2 folds randomly selected controls from rest of the children with pneumonia having no seizure. Prevalence and outcome of children with pneumonia and seizure were measured. Factors associated with seizure in children with pneumonia compared with those without seizure were also identified. Seizure was characterized by sudden, violent, involuntary, and abnormal repetitive movements with or without loss or impairment of consciousness confirmed by attending physician.

RESULTS

Among a total of 4101 children with pneumonia, 514 (12.5%) had seizure. Compared with children with pneumonia alone children having pneumonia and seizure more often developed respiratory failure (18% vs. 3%, P < 0.001) and died (13% vs. 3%, P < 0.001) during hospitalization. In logistic regression analysis hypoxemia (95% CI: 1.59-3.17, P < 0.001), severe pneumonia (95% CI: 2.13-6.52, P < 0.001), severe sepsis (95% CI: 1.30-2.88, P = 0.001), and hypernatremia (95% CI: 5.31-10.93, P < 0.001) were found to be independent risk factors for seizure. On the contrary, children with pneumonia having seizure were less likely to have severe acute malnutrition (95% CI: 0.26-0.50, P < 0.001).

CONCLUSIONS

Early identification of risk factors for seizure in children with pneumonia may be helpful for clinicians to promptly treat them and therefore may have potential to reduce deaths in those children especially in resource limited settings.

The predictors of outcome and progression of pediatric sepsis and septic shock: A prospective observational study from western India

Introduction:

There is a paucity of studies on the progression and outcome of Systemic Inflammatory Response Syndrome (SIRS) with its determinants.

Aims and Objectives:

To determine the predictors of the outcome and progression of pediatric sepsis and septic shock.

Materials and Methods:

Prospective observational study of children fulfilling criteria of SIRS and their progression to sepsis, severe sepsis, and septic shock (clinically and biochemically) was conducted at a tertiary care center.

Results:

Totally, 200 children were recruited over a period of 21 months (from February 2016 to October 2017). Most cases (80, 40%) were infants. Of the total, 188 (94%) cases were of an infective etiology (mostly respiratory system). Temperature and heart rate were the two commonest SIRS parameters which were deranged. Blood cultures were positive in only 25 (12.5%) cases. Out of the total 200 children, 108 progressed to sepsis, of which 26 progressed to severe sepsis, of which 22 progressed to septic shock. Abnormal leukocyte count, culture positivity and severe acute malnutrition were significantly associated with progression of SIRS patients to septic shock (P = 0.001, 0.00001 and 0.002, respectively). Factors associated with mortality were positive blood culture, multiorgan dysfunction, late hospital admissions, severe acute malnutrition, and requirement of supportive care (P values-<0.0001, <0.0001, 0.03, <0.0001 and <0.0001, respectively).

Conclusions:

SIRS can progress to septic shock if not identified early. The predictors of mortality were positive blood cultures, multiorgan dysfunction, late hospital admissions, severe acute malnutrition, and requirement of supportive care. The predictors of progression to septic shock were abnormal leukocyte count, culture positivity, and severe acute malnutrition.

Predictors of inpatient mortality among children hospitalized for severe acute malnutrition: a systematic review and meta-analysis

BACKGROUND

Malnutrition underlies 45% of under-5 deaths globally. Severe acute malnutrition (SAM) is the most serious form of undernutrition, characterized by wasting with or without edema. Mortality remains high (10%-40%) among children requiring hospitalization for complicated SAM.

OBJECTIVES

We aimed to systematically document the factors independently associated with inpatient mortality in children with SAM.

METHODS

Embase, Ovid MEDINE, the Cochrane Library, and clinicaltrials.gov were searched for articles published between January 2000 and January 2020, using a prespecified protocol. Eligible studies included children aged ≤59 mo hospitalized with SAM and used multivariable analysis to assess the baseline factors independently associated with inpatient mortality. Random-effects meta-analysis, stratified by the stated measure of effect, was used where >20% of studies included the same factor in analyses.

RESULTS

Twenty-eight of 1432 studies fulfilled inclusion criteria: 19 studies included all children with SAM and 9 included specific subgroups of children with SAM. All 19 main studies were from 8 countries across Africa, with a median of 400 children/study. The mean inpatient mortality was 15.7% (95% CI: 10.4%, 21.0%) and HIV prevalence ranged from 2.1% to 51%. Nine factors were included in the meta-analysis, stratified by HR and OR. HIV infection (HR: 4.32; 95% CI: 2.31, 8.08), weight-for-height z score (WHZ) (OR: 0.44; 95% CI: 0.24, 0.80), diarrhea (HR: 2.84; 95% CI: 1.40, 5.75), pneumonia (HR: 1.89; 95% CI: 1.19, 3.02), presence of shock (HR: 3.67; 95% CI: 2.24, 6.03), and lack of appetite (HR: 2.16; 95% CI: 1.48, 3.16) were associated with increased mortality, whereas child age and sex were not. The association between edema and mortality was difficult to ascertain from the available studies.

CONCLUSIONS

HIV infection, diarrhea, pneumonia, shock, lack of appetite, and lower WHZ are independent predictors of inpatient mortality in children with SAM. These factors may help to risk-stratify children being hospitalized with complicated SAM.This systematic review/meta-analysis protocol was registered at www.crd.york.ac.uk/prospero as CRD42019152267.

Predictor of Death in Diarrheal Children Under 5 Years of Age Having Severe Sepsis in an Urban Critical Care Ward in Bangladesh

We aimed to identify clinical predictors of fatal outcome in children under 5 years of age having diarrhea and severe sepsis and treated in the Intensive Care Unit of the Dhaka Hospital of icddr,b from October 2010 through September 2011. Among 191 enrolled children, 70 (37%) died and were considered to be cases, while the remaining 121 (63%) who survived constituted the controls. The cases more often had shortness of breath (SOB), septic shock, dehydrating diarrhea compared with the controls (for all, P < .05). After adjusting for potential confounders using logistic regression analysis, the likelihood of death was higher in children who had septic shock and SOB and lower in children having dehydrating diarrhea (for all, P < .05). Thus, SOB can trigger an early alarm for sepsis recognition; otherwise, these children can end up with fatality from septic shock. In resource-poor settings, early identification of these predictors can alleviate death.

Bacteremia in Diarrheal Children With Severe Pneumonia

Objectives. Diarrhea and pneumonia are the leading causes of under-5 childhood mortality. However, there is limited information on bacterial etiology of severe pneumonia in children with diarrhea. We analyzed bacterial pathogens from the blood of children under the age of 5 years. Methods. In this retrospective cross-sectional study, we studied all children having severe pneumonia with or without diarrhea admitted to the icddr,b (International Centre for Diarrheal Disease Research, Bangladesh) who had their blood culture done during January 2014 to December 2014. Results. Among a total of 159 study children, 118 had diarrhea. There were 13 bacterial isolates, and predominant organisms were gram-negative bacteria (11/13, 85%). Children with diarrhea coexisting with severe pneumonia proportionately had higher bacteremia (12/141 [10.16%] vs 1/41 [2.43%]), but the difference was not statistically insignificant (P = .186). Conclusion. We recognized that the coexistence of diarrhea and severe pneumonia had proportionately higher bacteremia, especially gram-negative bacteria compared with those without diarrhea. The results emphasize the trend of bacterial etiology of pneumonia in children with diarrhea and may warrant revised antibiotics guideline for their management.

Bacterial Resistance in Pneumonia in Developing Countries-A Role for Iron Chelation

Pneumonia represents one of the major infectious diseases in developing countries and is associated with high mortality, in particular in children under the age of five. The main causative bacterial agents are Streptococcus pneumoniae and Haemophilus influenzae type B, accounting for 33% and 16%, respectively, of the mortality in under-fives. Iron modulates the immune response in infectious diseases and increased iron levels can lead to complications such as sepsis and multiorgan failure. This review will look into the use of iron chelators in order to reduce microbial growth and attenuate a dysregulated immune response during infection. Our hypothesis is that temporary restriction of iron will lessen the incidence and complication rate of infections like pneumonia and result in a decrease of mortality and morbidity.

Health Outcomes, Pathogenesis and Epidemiology of Severe Acute Malnutrition (HOPE-SAM): rationale and methods of a longitudinal observational study

INTRODUCTION

Mortality among children hospitalised for complicated severe acute malnutrition (SAM) remains high despite the implementation of WHO guidelines, particularly in settings of high HIV prevalence. Children continue to be at high risk of morbidity, mortality and relapse after discharge from hospital although long-term outcomes are not well documented. Better understanding the pathogenesis of SAM and the factors associated with poor outcomes may inform new therapeutic interventions.

METHODS AND ANALYSIS

The Health Outcomes, Pathogenesis and Epidemiology of Severe Acute Malnutrition (HOPE-SAM) study is a longitudinal observational cohort that aims to evaluate the short-term and long-term clinical outcomes of HIV-positive and HIV-negative children with complicated SAM, and to identify the risk factors at admission and discharge from hospital that independently predict poor outcomes. Children aged 0-59 months hospitalised for SAM are being enrolled at three tertiary hospitals in Harare, Zimbabwe and Lusaka, Zambia. Longitudinal mortality, morbidity and nutritional data are being collected at admission, discharge and for 48 weeks post discharge. Nested laboratory substudies are exploring the role of enteropathy, gut microbiota, metabolomics and cellular immune function in the pathogenesis of SAM using stool, urine and blood collected from participants and from well-nourished controls.

ETHICS AND DISSEMINATION

The study is approved by the local and international institutional review boards in the participating countries (the Joint Research Ethics Committee of the University of Zimbabwe, Medical Research Council of Zimbabwe and University of Zambia Biomedical Research Ethics Committee) and the study sponsor (Queen Mary University of London). Caregivers provide written informed consent for each participant. Findings will be disseminated through peer-reviewed journals, conference presentations and to caregivers at face-to-face meetings.

A National Survey of Resources to Address Sepsis in Children in Tertiary Care Centers in Nigeria

Background: Infections leading to sepsis are major contributors to mortality and morbidity in children world-wide. Determining the capacity of pediatric hospitals in Nigeria to manage sepsis establishes an important baseline for quality-improvement interventions and resource allocations. Objectives: To assess the availability and functionality of resources and manpower for early detection and prompt management of sepsis in children at tertiary pediatric centers in Nigeria. Methods: This was an online survey of tertiary pediatric hospitals in Nigeria using a modified survey tool designed by the World Federation of Pediatric Intensive and Critical Care Societies (WFPICCS). The survey addressed all aspects of pediatric sepsis identification, management, barriers and readiness. Results: While majority of the hospitals 97% (28/29) reported having adequate triage systems, only 60% (16/27) follow some form of guideline for sepsis management. There was no consensus national guideline for management of pediatric sepsis. Over 50% of the respondents identified deficit in parental education, poor access to healthcare services, failure to diagnose sepsis at referring institutions, lack of medical equipment and lack of a definitive protocol for managing pediatric sepsis, as significant barriers. Conclusions: Certain sepsis-related interventions were reportedly widespread, however, there is no standardized sepsis protocol, and majority of the hospitals do not have pediatric intensive care units (PICU). These findings could guide quality improvement measures at institutional level, and healthcare policy/spending at the national level.

Determinants and Outcome of Metabolic Acidosis in Diarrheal Children Under 5 Years of Age in an Urban Critical Care Ward in Bangladesh

We evaluated the independent determinants and outcome of metabolic acidosis in diarrheal children. Children under 5 years of age admitted with diarrhea and severe respiratory distress in the critical care ward at Dhaka Hospital of icddr,b (International Centre for Diarrhoeal Disease Research, Bangladesh) from April 2010 to April 2014 who had their reports of arterial blood gas analyses were enrolled in the study. We compared clinical and laboratory characteristics between the study children with (cases = 74) and without metabolic acidosis (controls = 65). Metabolic acidosis was defined if pH < 7.35 and HCO₃ < 22 mmol/L in ABG. Cases had higher mortality (53% vs 29%, P = .01) compared to controls. After adjustment of potential confounders, for instance, hypokalemia and dehydration, the cases were independently associated with severe sepsis and raised serum creatinine (for both P < .05). Thus, early identification of these features of metabolic acidosis in diarrheal children may help clinicians to have prompt management that may further help reduce mortality in such children especially in resource-limited settings.

Hypoxaemia and septic shock were independent risk factors for mechanical ventilation in Bangladeshi children hospitalised for diarrhoea

AIM

In Bangladesh, approximately 6% of children under five years of age die due to diarrhoea. We evaluated the admission and hospitalisation risk factors for mechanical ventilation and outcomes in children with diarrhoea.

METHODS

This retrospective case-control chart analysis was conducted in the intensive care unit of Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh. We enrolled 219 children with diarrhoea aged 0-59 months between August 2009 and July 2013. The 73 cases were children who were initially identified as requiring mechanical ventilation during the study period, and the 146 controls were randomly selected from those who did not require mechanical ventilation. We compared the groups to determine the risk factors for mechanical ventilation.

RESULTS

Mortality was significantly higher among the cases than the controls (p < 0.001). In the logistic regression analysis carried out for two separate time points, the independent risk factors for mechanical ventilation on admission were hypoxaemia (p < 0.001) and septic shock (p = 0.004) and during hospitalisation, they were intake of intravenous fluid (p = 0.015), hypokalaemia (p = 0.018), hyperkalaemia (p = 0.005) and septic shock (p = 0.001).

CONCLUSION

Children under five with diarrhoea who required mechanical ventilation frequently had hypoxaemia and septic shock and were more likely to die than unventilated controls.

Ileus in children presenting with diarrhea and severe acute malnutrition: A chart review

Background

Severely malnourished children aged under five years requiring hospital admission for diarrheal illness frequently develop ileus during hospitalization with often fatal outcomes. However, there is no data on risk factors and outcome of ileus in such children. We intended to evaluate predictive factors for ileus during hospitalization and their outcomes.

Methodology/Principal findings

This was a retrospective chart review that enrolled severely malnourished children under five years old with diarrhea, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh between April 2011 and August 2012. We used electronic database to have our chart abstraction from previously admitted children in the hospital. The clinical and laboratory characteristics of children with (cases = 45), and without ileus (controls = 261) were compared. Cases were first identified by observation of abnormal bowel sounds on physical examination and confirmed with abdominal radiographs. For this comparison, Chi-square test was used to measure the difference in proportion, Student’s t-test to calculate the difference in mean for normally distributed data and Mann-Whitney test for data that were not normally distributed. Finally, in identifying independent risk factors for ileus, logistical regression analysis was performed. Ileus was defined if a child developed abdominal distension and had hyperactive or sluggish or absent bowel sound and a radiologic evidence of abdominal gas-fluid level during hospitalization. Logistic regression analysis adjusting for potential confounders revealed that the independent risk factors for admission for ileus were reluctance to feed (odds ratio [OR] = 3.22, 95% confidence interval [CI] = 1.24–8.39, p = 0.02), septic shock (OR = 3.62, 95% CI = 1.247–8.95, p<0.01), and hypokalemia (OR = 1.99, 95% CI = 1.03–3.86, p = 0.04). Mortality was significantly higher in cases compared to controls (22% vs. 8%, p<0.01) in univariate analysis; however, in multivariable regression analysis, after adjusting for potential confounders such as septic shock, no association was found between ileus and death (OR = 2.05, 95% CI = 0.68–6.14, p = 0.20). In a separate regression analysis model, after adjusting for potential confounders such as ileus, reluctance to feed, hypokalemia, hypocalcemia, and blood transfusion, septic shock (OR = 168.84, 95% CI = 19.27–1479.17, p<0.01) emerged as the only independent predictor of death in severely malnourished diarrheal children.

Conclusions/Significance

This study suggests that the identification of simple independent admission risk factors for ileus and risk factors for death in hospitalized severely malnourished diarrheal children may prompt clinicians to be more vigilant in managing these conditions, especially in resource-limited settings in order to decrease ileus and ileus-related fatal outcomes in such children.

Childhood malnutrition and diarrhea are important problems in lower and middle-income countries, including Bangladesh. Severe acute malnutrition (SAM) and diarrhea are responsible for more than one third of all deaths in children below five years old globally. Most of these deaths occur because of complications of SAM and/or diarrhea. SAM and diarrhea may simultaneously present in a child, often with serious complications. Ileus is a common fatal complication in such hospitalized children, and is accompanied by abdominal distension and hyperactive, sluggish, or absent bowel sounds heard using a stethoscope. Ileus is confirmed by radiologic evidence of multiple gas-fluid levels in the abdomen. However, the underlying factors contributing to ileus and its management in diarrheal children with severe acute malnutrition is unknown. Our study aimed to ascertain these risk factors and the outcome of ileus in such children by reviewing the data of previously admitted children between April 2011 and August 2012. Of 306 severely malnourished Bangladeshi under-five-year-old children with diarrhea enrolled for 17 months, 45 had ileus. Ileus was independently associated with a reluctance to feed, septic shock, and hypokalemia and had a higher case-fatality rate compared to those without ileus.

Presentation, management, and outcomes of sepsis in adults and children admitted to a rural Ugandan hospital: A prospective observational cohort study

Objectives

Limited data are available on sepsis in low-resource settings, particularly outside of urban referral centers. We conducted a prospective observational single-center cohort study in May 2013 to assess the presentation, management and outcomes of adult and pediatric patients admitted with sepsis to a community hospital in rural Uganda.

Methods

We consecutively screened all patients admitted to medical wards who met sepsis criteria. We evaluated eligible patients within 24 hours of presentation and 24–48 hours after admission, and followed them until hospital discharge. In addition to chart review, mental status evaluation, peripheral capillary oxygen saturation, and point-of-care venous whole blood lactate and glucose testing were performed.

Results

Of 56 eligible patients, we analyzed data on 51 (20 adults and 31 children). Median age was 8 years (IQR 2–23 years). Sepsis accounted for a quarter of all adult and pediatric medical ward admissions during the study period. HIV prevalence among adults was 30%. On enrollment, over half of patients had elevated point-of-care whole blood lactate, few were hypoglycemic or had altered mental status, and one third were hypoxic. Over 80% of patients received at least one antibiotic, all severely hypoxic patients received supplemental oxygen, and half of patients with elevated lactate received fluid resuscitation. The most common causes of sepsis were malaria and pneumonia. In-hospital mortality was 3.9%.

Conclusions

This study highlights the importance of sepsis among adult and pediatric patients admitted to a rural Ugandan hospital and underscores the need for continued research on sepsis in low resource settings.
