Abstract
OBJECTIVE To study clinical manifestations and outcome of hyponatremia and hypernatremia in children with diarrhea. METHOD We compared children aged 0-59 months hospitalized from 1 January to 31 December 2013 with hyponatremia (serum sodium <130 mmol/l), hypernatremia (serum sodium >150 mmol/l) and normonatremia (serum sodium 135-145 mmol/l). RESULTS The case fatality was significantly higher among the children with hypernatremia and hyponatremia than normonatremia. A logistic regression analysis adjusting for potential confounders revealed that children with hyponatremia are more likely to have convulsions, have severe acute malnutrition and be of older age compared with children with normal serum sodium. Children with hypernatremia are more likely to have convulsions and dehydration than normonatremic children (for all p < 0.05). CONCLUSION Early diagnosis and prompt management of hypo- and hypernatremia by identifying simple clinical predicting factors of these two conditions in diarrheal children <5 years of age is critically important to prevent deaths in such children, especially in resource-limited settings.

Abstract
Pneumonia and diarrhea are the 2 leading infectious causes of death in children younger than 5 years worldwide, most of which occur in low- and middle-income countries (LMICs) in sub-Saharan Africa and Southern Asia. The past decade has seen large reductions in global childhood mortality, partly due to expansion of nonspecific public health interventions and vaccines against Streptococcus pneumoniae, Haemophilus influenzae, and rotavirus in LMICs. Further progress in this field depends on the international community's commitment to fund and implement programs using currently available vaccines and development of new vaccines against pathogens common to children in LMICs.

Abstract
BACKGROUND Mortality due to pneumonia in children is more than any other illness. Limited data is available to predict mortality in children with pneumonia from central India. AIM To study predictors of mortality in children aged 1-59 months hospitalised with severe and very severe pneumonia. MATERIALS AND METHODS Present study was observational longitudinal study that was done in a tertiary care hospital of central India. Two hundred and ninety children, aged 1-59 months, presented with severe and very severe pneumonia were enrolled in this study. Outcome and predictors of mortality were studied. Data was analysed with Chi-square test, univariate and multivariate regression analysis. RESULTS Out of 270 enrolled study subjects, maximum (108, 37.24%) were belonged to 1-6-months age group. Proportion of mortality was maximum (16, 64.00%) in that age group. Overall case fatality rate was 8.62%. Among significant variables, delayed hospital referral [adjusted odds ratio (OR)-52.09, 95% confidence interval (CI)- 6.74-402.39], incomplete immunisation (OR-12.28, 95% CI-2.15-69.93), severe malnutrition (Z score < -3) (OR-15.51, 95% CI- 2.04-117.83), refusal to feed (OR- 30.57, 95% CI- 2.47-378.26), and hypoglycaemia (OR- 6.98, 95% CI- 1.05-46.30) were found significant independently on multivariate regression analysis. CONCLUSION Delayed hospital referral, incomplete immunisation, severe malnutrition, refusal to feed, and hypoglycaemia were independent predictors of mortality in children with severe and very severe pneumonia.

Abstract
Background Appropriate intervention is critical in reducing deaths among under-five, severe acutely malnourished (SAM) children with danger signs of severe pneumonia; however, there is paucity of data on outcome of World Health Organisation (WHO) recommended interventions of SAM children with severe pneumonia. We sought to evaluate outcome of the interventions in such children. Methods We prospectively enrolled SAM children aged 0–59 months, admitted to the Intensive Care Unit (ICU) or Acute Respiratory Infection (ARI) ward of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), between April 2011 and June 2012 with cough or respiratory difficulty and radiological pneumonia. All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111) and without WHO defined danger signs of severe pneumonia (n = 296). The outcomes of interest were treatment failure (if a child required changing of antibiotics) and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths. Results SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; p<0.001) and fatal outcome (21% vs. 4%; p<0.001) compared to those without danger signs. Only 6/111 (5.4%) SAM children with danger signs of severe pneumonia and 12/296 (4.0%) without danger signs had bacterial isolates from blood. In log-linear binomial regression analysis, after adjusting for potential confounders, danger signs of severe pneumonia, dehydration, hypocalcaemia, and bacteraemia were independently associated both with treatment failure and deaths in SAM children presenting with cough or respiratory difficulty and radiological pneumonia (p<0.01). Conclusion and Significance The result suggests that SAM children with cough or respiratory difficulty and radiologic pneumonia who had WHO-defined danger signs of severe pneumonia more often had treatment failure and fatal outcome compared to those without the danger signs. In addition to danger signs of severe pneumonia, other common causes of both treatment failure and deaths were dehydration, hypocalcaemia, and bacteraemia on admission. The result underscores the importance for further research especially a randomized, controlled clinical trial to validate standard WHO therapy in SAM children with pneumonia especially with danger signs of severe pneumonia to reduce treatment failures and deaths.

Abstract
BACKGROUND In developing countries, there is no published report on predicting factors of severe sepsis in severely acute malnourished (SAM) children having pneumonia and impact of fluid resuscitation in such children. Thus, we aimed to identify predicting factors for severe sepsis and assess the outcome of fluid resuscitation of such children. METHODS In this retrospective case-control study SAM children aged 0-59 months, admitted to the Intensive Care Unit (ICU) of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh from April 2011 through July 2012 with history of cough or difficult breathing and radiologic pneumonia, who were assessed for severe sepsis at admission constituted the study population. We compared the pneumonic SAM children with severe sepsis (cases = 50) with those without severe sepsis (controls = 354). Severe sepsis was defined with objective clinical criteria and managed with fluid resuscitation, in addition to antibiotic and other supportive therapy, following the standard hospital guideline, which is very similar to the WHO guideline. RESULTS The case-fatality-rate was significantly higher among the cases than the controls (40% vs. 4%; p<0.001). In logistic regression analysis after adjusting for potential confounders, lack of BCG vaccination, drowsiness, abdominal distension, acute kidney injury, and metabolic acidosis at admission remained as independent predicting factors for severe sepsis in pneumonic SAM children (p<0.05 for all comparisons). CONCLUSION AND SIGNIFICANCE We noted a much higher case fatality among under-five SAM children with pneumonia and severe sepsis who required fluid resuscitation in addition to standard antibiotic and other supportive therapy compared to those without severe sepsis. Independent risk factors and outcome of the management of severe sepsis in our study children highlight the importance for defining optimal fluid resuscitation therapy aiming at reducing the case fatality in such children.

Abstract
OBJECTIVE Stunting affects 26.7% of children worldwide, and little is known about its effects on the outcomes of childhood pneumonia. We evaluated the effect of stunting on the outcomes of pneumonia among children enrolled in two large clinical trials. METHODS We analysed data from two WHO and USAID-sponsored inpatient treatment trials, the Severe Pneumonia Evaluation Antimicrobial Research study (n = 958) and the Amoxicillin Penicillin Pneumonia International Study (n = 1702), which enrolled children aged 2-59 months across 16 sites in LMICs. We assessed the effect of stunting (height-for-age Z score < -2) on treatment outcome and time to resolution of hypoxaemic pneumonia. RESULTS Among 2542 (96%) children with valid data for height, 28% were stunted and 12.8% failed treatment by 5 days. The failure rate among stunted patients was 16.0% vs. 11.5% among non-stunted patients [unadjusted RR = 1.24 (95% CI 1.08, 1.41); adjusted RR = 1.28 (95% CI 1.10, 1.48)]. An inverse relationship was observed between height and failure rates, even among non-stunted children. Among 845 patients with hypoxaemic pneumonia, stunting was associated with a lower probability of normalisation of respiratory rate [HR = 0.63 (95% CI 0.52, 0.75)] and oxygen saturation [HR = 0.74 (95% CI 0.61, 0.89)]. CONCLUSIONS Stunting increases the risk of treatment failure and is associated with a longer course of recovery in children with pneumonia. Strategies to decrease stunting may decrease the burden of adverse outcomes in childhood pneumonia in low-resource settings.

Abstract
OBJECTIVE To investigate recognised co-morbidities and clinical management associated with inpatient pneumonia mortality in Malawian district hospitals. METHODS Prospective cohort study, of patient records, carried out in Malawi between 1st October 2000 and 30th June 2003. The study included all children aged 0-59 months admitted to the paediatric wards in sixteen district hospitals throughout Malawi with severe and very severe pneumonia. We compared individual factors between those that survived (n = 14 076) and those that died (n = 1 633). RESULTS From logistic regression analysis, predictors of death in hospital, adjusted for age, sex and severity grade included comorbid conditions of meningitis (OR =2.49, 95% CI 1.50-4.15), malnutrition (OR =2.37, 95% CI 1.94-2.88) and severe anaemia (OR =1.41, 95% CI 1.03-1.92). Requiring supplementary oxygen (OR =2.16, 95% CI 1.85-2.51) and intravenous fluids (OR =3.02, 95% CI 2.13-4.28) were associated with death while blood transfusion was no longer significant (OR =1.10, 95% CI 0.77-1.57) when the model included severe anaemia. CONCLUSIONS This study identified a number of challenges to improve outcome for Malawian infants and children hospitalised with pneumonia. These included improved assessment of co-morbidities and more rigorous application of standard case management.

Abstract
We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB) in children presenting with severe acute malnutrition (SAM) and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF) (cases = 27) and without PTB (controls = 81; randomly selected from 378 children) were compared. The cases more often had the history of contact with active PTB patient (P < .01) and exposure to cigarette smoke (P = .04) compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05) and positive tuberculin skin test (TST; P = .02). Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

Abstract
Respiratory and gastrointestinal infections are the top killers of children worldwide, and their co-occurrence is reported but not well understood. Our aim was to determine the risk factors for concurrent presentation of diarrhea and pneumonia (DP) in a resource-limited setting in Bangladesh. We used data from the Diarrheal Disease Surveillance System of the icddr,b Dhaka Hospital to identify children < 60 months of age with diarrhea and concurrent pneumonia, defined as a history of cough, an abnormal lung examination, and tachypnea. For the years 1996-2007, out of total 14,628 diarrheal patients surveyed, there were 607 (4%) patients who satisfied criteria for pneumonia. Those with DP had a higher mortality rate (4% versus 0.05%, odds ratio [OR] = 86, 95% confidence interval [CI] = 26-286) and a longer hospital stay (mean 84 versus 26 hours, difference 58 hours, 95% CI = 52-64 hours) than those with diarrhea (D) only. In multivariable logistic regression comparing cases (N = 607) with controls matched for month and year of admission at a ratio of 1:3 (N = 1,808), we found that DP was associated with younger age, male gender, severe acute malnutrition (SAM), less maternal education, lower family income, and lack of current breast-feeding history.

Abstract
OBJECTIVE To evaluate risk factors for death from acute lower respiratory infections (ALRI) in children in low- and middle-income countries. DESIGN Systematic review and meta-analysis. STUDY SELECTION Observational studies reporting on risk factors for death from ALRI in children below five years in low- and middle income countries. DATA SOURCES Medline, Embase, Global Health Library, Lilacs, and Web of Science to January 2014. RISK OF BIAS ASSESSMENT Quality In Prognosis Studies tool with minor adaptations to assess the risk of bias; funnel plots and Egger's test to evaluate publication bias. RESULTS Out of 10,655 papers retrieved, 77 studies from 39 countries (198,359 children) met the inclusion criteria. Host and disease characteristics more strongly associated with ALRI mortality were: diagnosis of very severe pneumonia as per WHO definition (odds ratio 9.42, 95% confidence interval 6.37‒13.92); age below two months (5.22, 1.70‒16.03); diagnosis of Pneumocystis Carinii (4.79, 2.67‒8.61), chronic underlying diseases (4.76, 3.27‒6.93); HIV/AIDS (4.68, 3.72‒5.90); and severe malnutrition (OR 4.27, 3.47‒5.25). Socio-economic and environmental factors significantly associated with increased odds of death from ALRI were: young maternal age (1.84, 1.03‒3.31); low maternal education (1.43, 1.13‒1.82); low socio-economic status (1.62, 1.32‒2.00); second-hand smoke exposure (1.52, 1.20 to 1.93); indoor air pollution (3.02, 2.11‒4.31). Immunisation (0.46, 0.36‒0.58) and good antenatal practices (0.50, 0.31‒0.81) were associated with decreased odds of death. CONCLUSIONS Host and disease characteristics as well as socio-economic and environmental determinants affect the risk of death from ALRI in children. Together with the prevention and treatment of chronic diseases, interventions to modify underlying risk factors such as poverty, lack of female education, and poor environmental conditions, should be considered among the strategies to reduce ALRI mortality in children in low- and middle-income countries.

Abstract
Pneumonia is a major cause of morbidity and mortality in infants and children worldwide, with most cases occurring in tuberculosis-endemic settings. Studies have emphasised the potential importance of Mycobacterium tuberculosis in acute severe pneumonia in children as a primary cause or underlying comorbidity, further emphasised by the changing aetiological range with rollout of bacterial conjugate vaccines in high mortality settings. We systematically reviewed clinical and autopsy studies done in tuberculosis-endemic settings that enrolled at least 100 children aged younger than 5 years with severe pneumonia, and that prospectively included a diagnostic approach to tuberculosis in all study participants. We noted substantial heterogeneity between studies in terms of study population and diagnostic methods. Of the 3644 patients who had culture of respiratory specimens for M tuberculosis undertaken, 275 (7·5%) were culture positive, and an acute presentation was common. Inpatient case-fatality rate for pneumonia associated with tuberculosis ranged from 4% to 21% in the four clinical studies that reported pathogen-related outcomes. Prospective studies are needed in high tuberculosis-burden settings to address whether tuberculosis is a cause or comorbidity of childhood acute severe pneumonia.

Abstract
The study aimed to investigate the aetiological agents and clinical presentations associated with acute lower respiratory infections (ALRI) among children under five years old at the Korle-Bu Teaching Hospital in Ghana. This was a cross-sectional study carried from February to December 2001. Nasopharyngeal aspirates and venous blood specimens obtained from 108 children with features suggestive of ALRI, were cultured and the isolated bacterial organisms were identified biochemically. Nasopharyngeal aspirates were also tested for Respiratory Syncitial Virus (RSV) antigen using a commercial kit (Becton Dickinson Directigen RSV test kit). A multiplex reverse transcription-PCR (RT-PCR) was also used to detect and characterize RSV using extracted RNA. Socio-demographic and clinical data were also obtained from the study subjects. Bronchopneumonia (55.5%), bronchiolitis (25%), lobar pneumonia (10.2), non-specific ALRI (4.6%), TB, bronchitis and respiratory distress (0.67%) were diagnosed. The prevalence of septicaemia was 10% and bacteria isolated were Staphylococcus aureus, Streptococcus pneumoniae and enteric bacteria, including Salmonella spp., Enterobacter spp and Klebsiella spp, were isolated. Out of the 108 cases, 18% tested positive for RSV, with two cases having RSV as the only aetiological pathogen detected. The subtyping analysis of RSV strains by a multiplex RT-PCR showed that subgroups A and B circulated in the season of analysis.

Abstract
Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice.

Abstract
Pneumonia remains one of the major killers of children in a middle-income country such as Morocco. A history of prematurity, a history of fever, leaving in a house with smokers, impaired consciousness, cyanosis, pallor, having ronchi on auscultation and human metapneumovirus infection are all independent risk factors for an adverse outcome. A history of asthma is independently associated with a positive outcome. Early identification of risk factors for an adverse outcome could improve overall prognosis.
Objectives Data on prognostic factors among children with severe pneumonia are scarce in middle-income countries. We investigated prognostic factors for an adverse outcome among children admitted to the Hôpital d’Enfants de Rabat, Morocco with World Health Organization-defined clinically severe pneumonia (CSP). Methods Children aged 2–59 months admitted to the hospital and fulfilling the CSP definition were recruited into this 13-month prospective study. A poor prognosis was defined as death, a need for intensive care, or a Respiratory Index of Severity in Children (RISC) score ≥3. Multivariate logistic regression was performed to ascertain independent predictive factors for a poor prognosis. Results Of the 689 children included in this analysis, 55 (8.0%) required intensive care and 28 died (4.0%). Five hundred and two (72.8%) children were classified as having a good prognosis and 187 (27.2%) as having a poor prognosis. A history of prematurity (odds ratio (OR) 2.50, 95% confidence interval (CI) 1.24–5.04), of fever (OR 2.25, 95% CI 1.32–3.83), living in a house with smokers (OR 1.79, 95% CI 1.18–2.72), impaired consciousness (OR 10.96, 95% CI 2.88–41.73), cyanosis (OR 2.09, 95% CI 1.05–4.15), pallor (OR 2.27, 95% CI 1.34–3.84), having rhonchi on auscultation (OR 2.45, 95% CI 1.58–3.79), and human metapneumovirus infection (OR 2.13, 95% CI 1.13–4.02) were all independent risk factors for an adverse outcome, whereas a history of asthma (OR 0.46, 95% CI 0.25–0.84) was the only independent risk factor for a positive outcome. Conclusions The early identification of factors associated with a poor prognosis could improve management strategies and the likelihood of survival of Moroccan children with severe pneumonia.

Abstract
BACKGROUND Post-discharge mortality among children with severe illness in resource-limited settings is under-recognized and there are limited data. We evaluated post-discharge mortality in a recently reported cohort of children with severe malnutrition and pneumonia, and identified characteristics associated with an increased risk of death. METHODS Young children (<5 years of age) with severe malnutrition (WHO criteria) and radiographic pneumonia on admission to Dhaka Hospital of icddr,b over a 15-month period were managed according to standard protocols. Those discharged were followed-up and survival status at 12 weeks post-discharge was determined. Verbal autopsy was requested from families of those that died. RESULTS Of 405 children hospitalized with severe malnutrition and pneumonia, 369 (median age, 10 months) were discharged alive with a follow-up plan. Of these, 32 (8.7%) died in the community within 3 months of discharge: median 22 (IQR 9-35) days from discharge to death. Most deaths were reportedly associated with acute onset of new respiratory or gastrointestinal symptoms. Those that died following discharge were significantly younger (median 6 [IQR 3,12] months) and more severely malnourished, on admission and on discharge, than those that survived. Bivariate analysis found that severe wasting on admission (OR 3.64, 95% CI 1.66-7.97) and age <12 months (OR 2.54, 95% CI 1.1-8.8) were significantly associated with post-discharge death. Of those that died in the community, none had attended a scheduled follow-up and care-seeking from a traditional healer was more common (p<0.001) compared to those who survived. CONCLUSION AND SIGNIFICANCE Post-discharge mortality was common in Bangladeshi children following inpatient care for severe malnutrition and pneumonia. The underlying contributing factors require a better understanding to inform the potential of interventions that could improve survival.

Abstract
BACKGROUND Malnourished children have increased risk of dying, with most deaths caused by infectious diseases. One mechanism behind this may be impaired immune function. However, this immune deficiency of malnutrition has not previously been systematically reviewed. OBJECTIVES To review the scientific literature about immune function in children with malnutrition. METHODS A systematic literature search was done in PubMed, and additional articles identified in reference lists and by correspondence with experts in the field. The inclusion criteria were studies investigating immune parameters in children aged 1-60 months, in relation to malnutrition, defined as wasting, underweight, stunting, or oedematous malnutrition. RESULTS The literature search yielded 3402 articles, of which 245 met the inclusion criteria. Most were published between 1970 and 1990, and only 33 after 2003. Malnutrition is associated with impaired gut-barrier function, reduced exocrine secretion of protective substances, and low levels of plasma complement. Lymphatic tissue, particularly the thymus, undergoes atrophy, and delayed-type hypersensitivity responses are reduced. Levels of antibodies produced after vaccination are reduced in severely malnourished children, but intact in moderate malnutrition. Cytokine patterns are skewed towards a Th2-response. Other immune parameters seem intact or elevated: leukocyte and lymphocyte counts are unaffected, and levels of immunoglobulins, particularly immunoglobulin A, are high. The acute phase response appears intact, and sometimes present in the absence of clinical infection. Limitations to the studies include their observational and often cross-sectional design and frequent confounding by infections in the children studied. CONCLUSION The immunological alterations associated with malnutrition in children may contribute to increased mortality. However, the underlying mechanisms are still inadequately understood, as well as why different types of malnutrition are associated with different immunological alterations. Better designed prospective studies are needed, based on current understanding of immunology and with state-of-the-art methods.

Abstract
OBJECTIVE To evaluate the pneumonia specific case fatality rate over time following the implementation of a Child Lung Health Programme (CLHP) within the existing government health services in Malawi to improve delivery of pneumonia case management. METHODS A prospective, nationwide public health intervention was studied to evaluate the impact on pneumonia specific case fatality rate (CFR) in infants and young children (0 to 59 months of age) following the implementation of the CLHP. The implementation was step-wise from October 1st 2000 until 31st December 2005 within paediatric inpatient wards in 24 of 25 district hospitals in Malawi. Data analysis compared recorded outcomes in the first three months of the intervention (the control period) to the period after that, looking at trend over time and variation by calendar month, age group, severity of disease and region of the country. The analysis was repeated standardizing the follow-up period by using only the first 15 months after implementation at each district hospital. FINDINGS Following implementation, 47,228 children were admitted to hospital for severe/very severe pneumonia with an overall CFR of 9.8%. In both analyses, the highest CFR was in the children 2 to 11 months, and those with very severe pneumonia. The majority (64%) of cases, 2-59 months, had severe pneumonia. In this group there was a significant effect of the intervention Odds Ratio (OR) 0.70 (95%CI: 0.50-0.98); p = 0.036), while in the same age group children treated for very severe pneumonia there was no interventional benefit (OR 0.97 (95%CI: 0.72-1.30); p = 0.8). No benefit was observed for neonates (OR 0.83 (95%CI: 0.56-1.22); p = 0.335). CONCLUSIONS The nationwide implementation of the CLHP significantly reduced CFR in Malawian infants and children (2-59 months) treated for severe pneumonia. Reasons for the lack of benefit for neonates, infants and children with very severe pneumonia requires further research.

Abstract
AIM To evaluate the clinical characteristics and outcome in children hospitalised with diarrhoea, comparing those developed septic shock with those who did not. METHODS We carried out a retrospective chart review on children aged 0-59 months admitted to the Dhaka Hospital, International Centre for Diarrhoeal Diseases Research, Bangladesh, with diarrhoea between October 2010 and September 2011. They were included if they had severe sepsis defined as tachycardia plus hyperthermia or hypothermia or an abnormal white blood cell count plus poor peripheral perfusion in absence of dehydration. Patients unresponsive to fluid and boluses, who required inotropes, were categorised as having septic shock (n = 88). The controls were those without septic shock (n = 116). RESULTS Death was significantly higher among the children with septic shock (67%) than the controls (14%) (p < 0.001). A logistic regression analysis, adjusted for potential confounders, found that children with septic shock were more likely to be drowsy on admission and received blood transfusions and mechanical ventilation (all p < 0.05). CONCLUSION Children hospitalised for diarrhoea with septic shock were more likely to die, be drowsy on admission and receive blood transfusions and mechanical ventilation. A randomised clinical trial on inotropes in children with diarrhoea, severe sepsis and drowsiness may expedite their use and prevent mechanical ventilation and deaths.

Abstract
We sought to examine the factors associated with bacteraemia and their outcome in children with pneumonia and severe acute malnutrition (SAM). All SAM children of either sex, aged 0-59 months, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh with radiologically confirmed pneumonia from April 2011 to July 2012 were enrolled (n = 405). Comparison was made between pneumonic SAM children with (cases = 18), and without (controls = 387) bacteraemia. The death rate was significantly higher in cases than controls (28% vs. 8%, P < 0·01). In logistic regression analysis, after adjusting for potential confounders, the SAM children with pneumonia and bacteraemia more often had a history of lack of bacillus Calmette-Guérin (BCG) vaccination (odds ratio 7·39, 95% confidence interval 1·67-32·73, P < 0·01). The results indicate the importance of continuation of BCG vaccination which may provide benefit beyond its primary purpose.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a major cause of adult mortality in Asia. Appropriate empirical treatment depends on knowledge of the pathogens commonly responsible. However, assessing the aetiological significance of identified organisms is often difficult, particularly with sputum isolates that might represent contamination with oropharyngeal flora. METHODS A systematic review of all adult CAP aetiology studies from Asia, excluding the Middle East, published in English between 1 January 1990 and 1 March 2012 was conducted. Forty-eight studies reporting on 10 423 patients were included, representing data from China, India, Indonesia, Japan, Malaysia, The Philippines, Singapore, South Korea, Taiwan, Thailand and Vietnam. Data from large parts of Asia were unavailable and there was substantial heterogeneity in methodology. RESULTS As in western studies, Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydophila pneumoniae, Legionella spp. and Haemophilus influenzae were all significant pathogens. However, compared with western studies, S. pneumoniae was of less relative importance. Gram-negative bacilli and Mycobacterium tuberculosis were more important, and in northeast Thailand Burkholderia pseudomallei was a major pathogen. CONCLUSION These data have major implications for diagnostic strategies and empirical treatment. Narrow-spectrum antibiotics targeting S. pneumoniae may be inappropriate in many Asian settings, and agents active against TB may lead to partial response and delayed TB diagnosis.

Abstract
BACKGROUND Severe malnutrition is a risk factor for pneumonia due to a wide range of pathogens but aetiological data are limited and the role of Mycobacterium tuberculosis is uncertain. METHODS We prospectively investigated severely malnourished young children (<5 years) with radiological pneumonia admitted over a 15-month period. Investigations included blood culture, sputa for microscopy and mycobacterial culture. Xpert MTB/RIF assay was introduced during the study. Study children were followed for 12 weeks following their discharge from the hospital. RESULTS 405 eligible children were enrolled, with a median age of 10 months. Bacterial pathogens were isolated from blood culture in 18 (4.4%) children, of which 72% were Gram negatives. Tuberculosis was confirmed microbiologically in 7% (27/396) of children that provided sputum - 10 by culture, 21 by Xpert MTB/RIF assay, and 4 by both tests. The diagnostic yield from induced sputum was 6% compared to 3.5% from gastric aspirate. Sixty (16%) additional children had tuberculosis diagnosed clinically that was not microbiologically confirmed. Most confirmed tuberculosis cases did not have a positive contact history or positive tuberculin test. The sensitivity and specificity of Xpert MTB/RIF assay compared to culture was 67% (95% CI: 24-94) and 92% (95% CI: 87-95) respectively. Overall case-fatality rate was 17% and half of the deaths occurred in home following discharge from the hospital. CONCLUSION AND SIGNIFICANCE TB was common in severely malnourished Bangladeshi children with pneumonia. X-pert MTB/RIF assay provided higher case detection rate compared to sputum microscopy and culture. The high mortality among the study children underscores the need for further research aimed at improved case detection and management for better outcomes.

Abstract
BACKGROUND Early recognition of bacterial infections is crucial for their proper management, but is particularly difficult in children with severe acute malnutrition (SAM). The objectives of this study were to evaluate the accuracy of C-reactive protein (CRP) and procalcitonin (PCT) for diagnosing bacterial infections and assessing the prognosis of hospitalized children with SAM, and to determine the reliability of CRP and PCT rapid tests suitable for remote settings. METHODS From November 2007 to July 2008, we prospectively recruited 311 children aged 6 to 59 months hospitalized with SAM plus a medical complication in Maradi, Niger. Blood, urine, and stool cultures and chest radiography were performed systematically on admission. CRP and PCT were measured by rapid tests and by reference quantitative methods using frozen serum sent to a reference laboratory. RESULTS Median CRP and PCT levels were higher in children with bacteremia or pneumonia than in those with no proven bacterial infection (P < .002). However, both markers performed poorly in identifying invasive bacterial infection, with areas under the curve of 0.64 and 0.67 before and after excluding children with malaria, respectively. At a threshold of 40 mg/L, CRP was the best predictor of death (81% sensitivity, 58% specificity). Rapid test results were consistent with those from reference methods. CONCLUSIONS CRP and PCT are not sufficiently accurate for diagnosing invasive bacterial infections in this population of hospitalized children with complicated SAM. However, a rapid CRP test could be useful in these settings to identify children most at risk for dying.

Abstract
AIM The goal of this study was to compare the current guidelines on diagnosis and treatment of paediatric community-acquired pneumonia (CAP) in developing and developed countries. METHODS A literature search was performed consulting the Medline, Embase, Current Contents, National Guideline Clearinghouse and Cochrane database, from January 2000 to March 2013. RESULTS Twelve guidelines were selected: six from developed countries and six from developing countries. Major discrepancies between the diagnosis and treatment approaches recommended by guidelines covering developing and developed countries were revealed. The search also highlighted differences between recommendations issued in similar settings. CONCLUSION The guidelines show wide variations and weak recommendations and further research is needed to improve clinical outcomes and make better use of resources.

Abstract
OBJECTIVES High acute respiratory tract infection (ARTI) rates are observed in indigenous populations. We assessed the role of viral infections and nasopharyngeal bacterial carriage in ARTIs in Eñepa Amerindians from Venezuela. METHODS In 40 children aged 0-10 years with ARTIs, healthy nearest-age sibling controls and their mothers the presence of Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Moraxella catarrhalis, Mycoplasma pneumoniae, Chlamydophila pneumoniae/psittachi and 15 respiratory viruses was investigated. RESULTS S. pneumoniae was the most frequently detected pathogen, with carriage rates of 75% and 38% in children and mothers respectively. In children, S. pneumoniae carriage was associated with ARTI risk in multivariate analysis (OR 14.1, 95% CI 1.4-137.7). Viral infections were not associated with ARTI risk. S. pneumoniae carriage was common in children of all ages while viral co-infections were more frequently present in children under 4 years compared to older children (46% vs. 17%, p < 0.01). An increase of one unit height-for-age Z score (i.e. improved chronic nutritional status) was associated with decreased odds of S. pneumoniae colonization in multivariate analysis (OR 0.66, 95% CI 0.44-0.99). CONCLUSIONS In Eñepa children high S. pneumoniae carriage rates associated with a poor nutritional status contribute to the development of ARTIs.

Clinical risk factors of death from pneumonia in children with severe acute malnutrition in an urban critical care ward of Bangladesh. PLoS One 2013; 8:e73728.

Abstract
Background Risks of death are high when children with pneumonia also have severe acute malnutrition (SAM) as a co-morbidity. However, there is limited published information on risk factors of death from pneumonia in SAM children. We evaluated clinically identifiable factors associated with death in under-five children who were hospitalized for the management of pneumonia and SAM. Methods For this unmatched case-control design, SAM children of either sex, aged 0–59 months, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) during April 2011 to July 2012 with radiological pneumonia were studied. The SAM children with pneumonia who had fatal outcome constituted the cases (n = 35), and randomly selected SAM children with pneumonia who survived constituted controls (n = 105). Results The median (inter-quartile range) age (months) was comparable among the cases and the controls [8.0 (4.9, 11.0) vs. 9.7 (5.0, 18.0); p = 0.210)]. In logistic regression analysis, after adjusting for potential confounders, such as vomiting, abnormal mental status, and systolic hypotension (<70 mm of Hg) in absence of dehydration, fatal cases of severely malnourished under-five children with pneumonia were more often hypoxemic (OR = 23.15, 95% CI = 4.38–122.42), had clinical dehydration (some/severe) (OR = 9.48, 95% CI = 2.42–37.19), abdominal distension at admission (OR = 4.41, 95% CI = 1.12–16.52), and received blood transfusion (OR = 5.50, 95% CI = 1.21–24.99) for the management of crystalloid resistant systolic hypotension. Conclusion and Significance We identified hypoxemia, clinical dehydration, and abdominal distension as the independent predictors of death in SAM children with pneumonia. SAM children with pneumonia who required blood transfusion for the management of crystalloid resistant systolic hypotension were also at risk for death. Thus, early identification and prompt management of these simple clinically recognizable predictors of death and discourage the use of blood transfusion for the management of crystalloid resistant systolic hypotension may help reduce deaths in such population.

Abstract
BACKGROUND The World Health Organization (WHO) recommends using age-specific respiratory rates for diagnosing pneumonia in children. Past studies have evaluated the WHO criteria with mixed results. OBJECTIVE We examined the accuracy of clinical and laboratory factors for diagnosing pediatric pneumonia in resource-limited settings. METHODS We conducted a retrospective chart review of children under 5 years of age presenting with respiratory complaints to three rural hospitals in Rwanda who had received a chest radiograph. Data were collected on the presence or absence of 31 historical, clinical, and laboratory signs. Chest radiographs were interpreted by pediatric radiologists as the gold standard for diagnosing pneumonia. Overall correlation and test characteristics were calculated for each categorical variable as compared to the gold standard. For continuous variables, we created receiver operating characteristic (ROC) curves to determine their accuracy for predicting pneumonia. RESULTS Between May 2011 and April 2012, data were collected from 147 charts of children with respiratory complaints. Approximately 58% of our sample had radiologist-diagnosed pneumonia. Of the categorical variables, a negative blood smear for malaria (χ(2) = 6.21, p = 0.013) and the absence of history of asthma (χ(2) = 4.48, p = 0.034) were statistically associated with pneumonia. Of the continuous variables, only oxygen saturation had a statistically significant area under the ROC curve (AUC) of 0.675 (95% confidence interval [CI] 0.581-0.769 and p = 0.001). Respiratory rate had an AUC of 0.528 (95% CI 0.428-0.627 and p = 0.588). CONCLUSION Oxygen saturation was the best clinical predictor for pediatric pneumonia and should be further studied in a prospective sample of children with respiratory symptoms in a resource-limited setting.

Abstract
Background Although malnutrition affects thousands of children throughout the Sahel each year and predisposes them to infections, there is little data on the etiology of infections in these populations. We present a clinical and biological characterization of infections in hospitalized children with complicated severe acute malnutrition (SAM) in Maradi, Niger. Methods Children with complicated SAM hospitalized in the intensive care unit of a therapeutic feeding center, with no antibiotics in the previous 7 days, were included. A clinical examination, blood, urine and stool cultures, and chest radiography were performed systematically on admission. Results Among the 311 children included in the study, gastroenteritis was the most frequent clinical diagnosis on admission, followed by respiratory tract infections and malaria. Blood or urine culture was positive in 17% and 16% of cases, respectively, and 36% had abnormal chest radiography. Enterobacteria were sensitive to most antibiotics, except amoxicillin and cotrimoxazole. Twenty-nine (9%) children died, most frequently from sepsis. Clinical signs were poor indicators of infection and initial diagnoses correlated poorly with biologically or radiography-confirmed diagnoses. Conclusions These data confirm the high level of infections and poor correlation with clinical signs in children with complicated SAM, and provide antibiotic resistance profiles from an area with limited microbiological data. These results contribute unique data to the ongoing debate on the use and choice of broad-spectrum antibiotics as first-line treatment in children with complicated SAM and reinforce the call for an update of international guidelines on management of complicated SAM based on more recent data.

Abstract
Few children with drug-resistant (DR) tuberculosis (TB) are identified, diagnosed, and given an appropriate treatment. The few studies that have described this vulnerable population have used inconsistent definitions. The World Health Organization (WHO) definitions used for adults with DR-TB and for children with drug-susceptible TB are not always appropriate for children with DR-TB. The Sentinel Project on Pediatric Drug-Resistant Tuberculosis was formed in 2011 as a network of experts and stakeholders in childhood DR-TB. An early priority was to establish standardized definitions for key parameters in order to facilitate study comparisons and the development of an evidence base to guide future clinical management. This consensus statement proposes standardized definitions to be used in research. In particular, it suggests consistent terminology, as well as definitions for measures of exposure, drug resistance testing, previous episodes and treatment, certainty of diagnosis, site and severity of disease, adverse events, and treatment outcome.

Abstract
Nearly all global mortality in children younger than 5 years (99%) occurs in developing countries. The leading causes of mortality in children younger than 5 years worldwide, pneumonia and diarrhoeal illness, account for 1·396 and 0·801 million annual deaths, respectively. Although important advances in prevention are being made, advanced life support management in children in developing countries is often incomplete because of limited resources. Existing advanced life support management guidelines for children in limited-resource settings are mainly empirical, rather than evidence-based, written for the hospital setting, not standardised with a systematic approach to patient assessment and categorisation of illness, and taught in current paediatric advanced life support training courses from the perspective of full-resource settings. In this Review, we focus on extension of higher quality emergency and critical care services to children in developing countries. When integrated into existing primary care programmes, simple inexpensive advanced life support management can improve child survival worldwide.

Predictors and outcome of hypoxemia in severely malnourished children under five with pneumonia: a case control design. PLoS One 2013; 8:e51376. [PMID: 23320066 PMCID: PMC3540031 DOI: 10.1371/journal.pone.0051376] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2012] [Accepted: 11/05/2012] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND There is lack of information in the medical literature on predictors of hypoxemia in severely malnourished children with pneumonia, although hypoxemia is common and is often associated with fatal outcome in this population. We explored the predictors of hypoxemia in under-five children who were hospitalized for the management of pneumonia and severe acute malnutrition (SAM). METHODS In this unmatched case-control design, SAM children of both sexes, aged 0-59 months, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) with radiological pneumonia and hypoxemia during April 2011 to April 2012 were studied. SAM children with pneumonia and hypoxemia (SpO(2)<90%) constituted the cases (n = 37), and randomly selected SAM children with pneumonia but without hypoxemia constituted controls (n = 111). RESULTS The case-fatality was significantly higher among the cases than the controls (30% vs. 4%; p<0.001). In logistic regression analysis, after adjusting for potential confounders such as nasal flaring, head nodding, inability to drink, and crackles in lungs, fast breathing (95% CI = 1.09-13.55), lower chest wall in-drawing (95% CI = 2.48-43.41), and convulsion at admission (95% CI = 3.14-234.01) were identified as independent predictors of hypoxemia in this population. The sensitivity of fast breathing, lower chest wall in-drawing and convulsion at admission and their 95% confidence intervals (CI) to predict hypoxemia were 84 (67-93)%, 89 (74-96)%, and 19 (9-36)% respectively, and their specificity were 53 (43-63)%, 60 (51-69)% and 98 (93-100)% respectively. CONCLUSION AND SIGNIFICANCE Fast breathing and lower chest wall in-drawing were the best predictors of hypoxemia in SAM children with pneumonia. There thus, in resources poor settings where pulse oximetry is not available, identification of these simple clinical predictors of hypoxemia in such children could be reliably used for early O(2) supplementation in addition to other appropriate management to reduce morbidity and deaths.

Abstract
UNLABELLED The aim of this study was to evaluate the effects of bacterial pneumonia and malnutrition on the frequency of micronuclei (MN) in peripheral blood of pediatric patients through flow cytometric analysis. The study was an analytical case-control study carried out on 35 malnourished children with bacterial pneumonia and 20 well-nourished children with bacterial pneumonia, in addition to 20 healthy children as controls. Complete physical examination including; anthropometric measurement, Chest roentgenograms were done for all cases. Assessment of MN was done by FACSCalibur flow cytometry. The frequency of micronucleated reticulocytes (MN-RETs) was higher both in the malnourished children with pneumonia and well-nourished children with pneumonia than the controls. Within the malnourished children with pneumonia, patients with kwashiorkor had more micronucleated mature erythrocytes (MN-RBCs) and MN-RETs than patients with marasmus. IN CONCLUSION Pneumonia is associated with an increased frequency of MN and this increment is more pronounced in children with severe malnutrition especially kwashiorkor group.

Clinical predictors and outcome of metabolic acidosis in under-five children admitted to an urban hospital in Bangladesh with diarrhea and pneumonia. PLoS One 2012; 7:e39164. [PMID: 22720060 PMCID: PMC3376101 DOI: 10.1371/journal.pone.0039164] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2012] [Accepted: 05/17/2012] [Indexed: 12/01/2022] Open
Abstract
Background Clinical features of metabolic acidosis and pneumonia frequently overlap in young diarrheal children, resulting in differentiation from each other very difficult. However, there is no published data on the predictors of metabolic acidosis in diarrheal children also having pneumonia. Our objective was to evaluate clinical predictors of metabolic acidosis in under-five diarrheal children with radiological pneumonia, and their outcome. Methods We prospectively enrolled all under-five children (n = 164) admitted to the Special Care Ward (SCW) of the Dhaka Hospital of icddr, b between September and December 2007 with diarrhea and radiological pneumonia who also had their total serum carbon-dioxide estimated. We compared the clinical features and outcome of children with radiological pneumonia and diarrhea with (n = 98) and without metabolic acidosis (n = 66). Results Children with metabolic acidosis more often had higher case-fatality (16% vs. 5%, p = 0.039) compared to those without metabolic acidosis on admission. In logistic regression analysis, after adjusting for potential confounders such as age of the patient, fever on admission, and severe wasting, the independent predictors of metabolic acidosis in under-five diarrheal children having pneumonia were clinical dehydration (OR 3.57, 95% CI 1.62–7.89, p = 0.002), and low systolic blood pressure even after full rehydration (OR 1.02, 95% CI 1.01–1.04, p = 0.005). Proportions of children with cough, respiratory rate/minute, lower chest wall indrawing, nasal flaring, head nodding, grunting respiration, and cyanosis were comparable (p>0.05) among the groups. Conclusion and Significance Under-five diarrheal children with radiological pneumonia having metabolic acidosis had frequent fatal outcome than those without acidosis. Clinical dehydration and persistent systolic hypotension even after adequate rehydration were independent clinical predictors of metabolic acidosis among the children. However, metabolic acidosis in young diarrheal children had no impact on the diagnostic clinical features of radiological pneumonia which underscores the importance of early initiation of appropriate antibiotics to combat morbidity and deaths in such population.

Abstract
BACKGROUND There is limited information on risk factors for pneumonia and pneumonia-related deaths in children who also have diarrhoea. AIM To identify risk factors for the above in order to improve strategies for case management and to develop appropriate public health messages. METHODS All children under 5 years of age admitted to the Special Care Ward, Dhaka Hospital of the International Centre for Diarrhoeal Disease Research (ICDDR,B) from 1 September to 31 December 2007 were considered for enrollment if they also had diarrhoea. Of the 258 children with diarrhoea enrolled, those with (n=198) or without (n=60) WHO-defined pneumonia constituted the pneumonia and comparison groups, respectively. Among the 198 children with pneumonia, children who survived (n=174) were compared with those who died in hospital (n=24). RESULTS After adjusting for socio-demographic factors, including low levels of literacy of either parent, low household income, not having a window or exhaust fan in the kitchen, household smoking and over-crowding, children with pneumonia were more likely to sleep on a bare wooden-slatted or bamboo bed (OR 2·7, 95% CI 1·40-5·21, p = 0·003) than on other bedding, and were also more likely to have a parent/care-giver with poor knowledge of pneumonia (OR 1·94, 95% CI 1·02-3·70, p=0·043). Independent risk factors for death include severe underweight (OR 5·2, 95% CI 1·2-22·0, p=0·03), hypoxaemia (OR 17·5, 95% CI I 1·9-160·0, p=0·01), severe sepsis (OR 8·7, 95% CI I 1·8-41·5, p=0·007) and lobar consolidation (OR 11·9, 95% CI 2·3-61·6, p=0·003). CONCLUSIONS Increased public awareness of signs of pneumonia and severe sepsis in children under 5 is important to mitigate the risks of pneumonia and pneumonia-related deaths, and the importance of appropriate bedding for young children in reducing the risk of pneumonia needs to be addressed.

Abstract
Objective Pneumonia is a leading cause of death in children worldwide. A simple clinical score predicting the probability of death in a young child with lower respiratory tract infection (LRTI) could aid clinicians in case management and provide a standardized severity measure during epidemiologic studies. Methods We analyzed 4,148 LRTI hospitalizations in children <24 months enrolled in a pneumococcal conjugate vaccine trial in South Africa from 1998–2001, to develop the Respiratory Index of Severity in Children (RISC). Using clinical data at admission, a multivariable logistic regression model for mortality was developed and statistically evaluated using bootstrap resampling techniques. Points were assigned to risk factors based on their coefficients in the multivariable model. A child's RISC score is the sum of points for each risk factor present. Separate models were developed for HIV-infected and non-infected children. Results Significant risk factors for HIV-infected and non-infected children included low oxygen saturation, chest indrawing, wheezing, and refusal to feed. The models also included age and HIV clinical classification (for HIV-infected children) or weight-for-age (for non-infected children). RISC scores ranged up to 7 points for HIV-infected or 6 points for non-infected children and correlated with probability of death (0–47%, HIV-infected; 0–14%, non-infected). Final models showed good discrimination (area under the ROC curve) and calibration (goodness-of-fit). Conclusion The RISC score incorporates a simple set of risk factors that accurately discriminate between young children based on their risk of death from LRTI, and may provide an objective means to quantify severity based on the risk of mortality.

Abstract
BACKGROUND The shift to test-based management of malaria represents an important departure from established practice under the Integrated Management of Childhood Illnesses (IMCI). The possibility of false results of tests for malaria and co-morbidity, however, make it important that guidelines in IMCI case assessment are still followed. METHODS AND FINDINGS We conducted a cross-sectional observational study to evaluate current practices in IMCI-based assessment of febrile children in 10 health centres and 5 district hospitals, with follow up of a subset of children to determine day 7-10 post-treatment clinical outcome. Clinical consultation, examination and prescribing practices were recorded using a checklist by trained non-medical observers. The facility case management of 1,983 under-five years old febrile children was observed and 593 followed up at home on days 5-10. The mean number of tasks performed from the 11 tasks expected to be done by the IMCI guidelines was 6 (SD 1.6). More than 6 tasks were performed in only 35% of children and this varied substantially between health facilities (range 3-85%). All 11 tasks were performed in only 1% of children. The most commonly performed tasks were temperature measurement (91%) and weighing (88%). Respiratory rate was checked in only 4% of children presenting with cough or difficulty in breathing. The likelihood of performing "better than average number of tasks" (>6) was higher when the consultation was done by medical assistants than doctors (O.R. = 3.16, 1.02-9.20). The number of tasks performed during assessment did not, however, influence clinical outcome (O.R. = 1.02, 0.83-1.24). CONCLUSION Facility-tailored interventions are needed to improve adherence to IMCI guidelines incorporating test-based management of malaria. Studies are needed to re-evaluate the continued validity of tasks defined in IMCI case assessment guidelines.

Abstract
AIM To evaluate the clinical and laboratory predictors of death in hospitalized under-five children with diarrhoea. METHODS This is a prospective cohort study carried out in the Special Care Ward (SCW) of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), Dhaka, Bangladesh. All admitted diarrhoeal children of both sexes, aged 0-59 months, from September 2007 through December 2007 were enrolled. We compared and analysed factors among diarrhoeal children who died (n = 29) with those who survived (n = 229). RESULTS In logistic regression analysis, after adjusting for potential confounders (infusion of intravenous fluid and immature PMN), absent peripheral pulse even after complete rehydration (OR 10.9, 95% CI 2.1-56.8; p < 0.01), severe malnutrition (OR 7.9, 95% CI 1.8-34.8; p < 0.01), hypoxaemia (OR 8.5, 95% CI 1.0-75.0; p = 0.05), radiological lobar pneumonia (OR 17.8, 95% CI 3.7-84.5; p < 0.01) and hypernatraemia (OR 15.8, 95% CI 3.0-81.8; p < 0.01) were independently associated with deaths among diarrhoeal children admitted to SCW. CONCLUSIONS Thus, the absence of peripheral pulses even after full rehydration, severe malnutrition, hypoxaemia, lobar pneumonia and hypernatraemia are independent predictors of death among the under-five children with diarrhoea admitted to critical care ward of a resource-limited setting in Bangladesh.

Abstract
BACKGROUND Caloric insufficiency during the first week of ICU stay has been associated with increased infection rates. The connection between specific pathogens and host nutritional status in the ICU is not well known. This study was undertaken to determine the impact of patients' early in-ICU energy balance on the pathogens responsible for ventilator-associated pneumonia (VAP). METHODS In this prospective, observational, cohort study conducted in a teaching hospital ICU, energy balance (energy delivered - calculated resting energy expenditure) was compared according to the microbiologic results of the fiber-optic BAL cultures of 76 consecutive patients receiving acute prolonged (≥ 96 h) mechanical ventilation who developed VAP during their ICU stay. RESULTS Among the 76 BAL cultures, 22 contained significant Staphylococcus aureus concentrations. The cumulated energy deficit of patients with S aureus VAP was greater than those with VAP caused by other pathogens (-10,275 ± 4,211 kcal vs -7,376 ± 4,013 kcal from ICU admission to day of BAL, P < .01). ICU admission, nutritional status, and conditions potentially limiting feeding did not differ significantly between the two groups. Patients with S aureus VAP had lower prescribed and delivered energy, causing higher energy deficits. Multivariate analysis identified energy deficit as being independently associated with S aureus VAP. More-severe energy deficit and higher rate of S aureus-positive BAL cultures (P = .01 comparing quartiles) were observed. CONCLUSIONS Early ICU energy deficit is an independent determinant for acquiring S aureus VAP in patients on acute prolonged mechanical ventilation.

Abstract
Community acquired pneumonia is the leading killer of children under the age of 5 years. In ER, a diagnosis of pneumonia may be made and the severity graded on basis of WHO's classification for pneumonia in children up to 5 years of age. It relies on age-specific respiratory rate, presence of lower chest indrawing and signs of severe illness. A diagnosis of pneumonia is made if a febrile child has history of cough and difficult or rapid breathing and a respiratory rate above age specific threshold; however, signs of airway obstruction should be ruled out. Severe pneumonia is diagnosed if with the above features lower chest wall retraction is present; nonetheless, all infants below 2 months and children with moderate to severe malnutrition with pneumonia are categorized as having severe pneumonia. A chest radiograph is indicated only if the diagnosis is in doubt; complications are suspected and there is severe/very severe or recurrent pneumonia. Non-severe pneumonia is treated at home with oral amoxicillin for 3-5 days. If there is no improvement in 48 h it is changed to amoxicillin-clavulanate. Azithromycin is added for atypical pneumonia. Indications for hospitalization include age <2 months, treatment failure on oral antibiotics, severe/very severe or recurrent pneumonia, shock, hypoxemia, severe malnutrition, immunocompromised state. Severe pneumonia is treated with injectable ampicillin; Cloxacillin is added if clinical/radiographic features suggest Staphylococcal infection. On review after 48 h, if improved, the child may be sent home on oral amoxicillin for 5 more days; if not, it is treated as very severe pneumonia. Very severe pneumonia is treated with injectable Ampicillin plus gentamicin. If improved after 48 h, oral amoxicillin and gentamicin are continued for 10 days. If not, respiratory support is enhanced, antibiotics are changed to intravenous ceftriaxone and amikacin and further work up is planned. Children with chronic diseases and recurrent pneumonia require specific antibiotics depending on the underlying cause.

Abstract
BACKGROUND Scaling up of evidence based management of childhood acute respiratory infection/pneumonia, is a public health priority in India, and necessitates robust literature review, for advocacy and action. OBJECTIVE To identify, synthesize and summarize current evidence to guide scaling up of management of childhood acute respiratory infection/pneumonia in India, and identify existing knowledge gaps. METHODS A set of ten questions pertaining to the management (prevention, treatment, and control) of childhood ARI/pneumonia was identified through a consultative process. A modified systematic review process developed a priori was used to identify, synthesize and summarize, research evidence and operational information, pertaining to the problem in India. Areas with limited or no evidence were identified as knowledge gaps. RESULTS Childhood ARI/pneumonia is a significant public health problem in India, although robust epidemiological data is not available on its incidence. Mortality due to pneumonia accounts for approximately one-fourth of the total deaths in under five children, in India. Pneumonia affects children irrespective of socioeconomic status; with higher risk among young infants, malnourished children, non-exclusively breastfed children and those with exposure to solid fuel use. There is lack of robust nation-wide data on etiology; bacteria (including Pneumococcus, H. influenzae, S. aureus and Gram negative bacilli), viruses (especially RSV) and Mycoplasma, are the common organisms identified. In-vitro resistance to cotrimoxazole is high. Wheezing is commonly associated with ARI/pneumonia in children, but difficult to appreciate without auscultation. The current WHO guidelines as modified by IndiaCLEN Task force on Penumonia (2010), are sufficient for case-management of childhood pneumonia. Other important interventions to prevent mortality are oxygen therapy for those with severe or very severe pneumonia and measles vaccination for all infants. There is insufficient evidence for protective or curative effect of vitamin A; zinc supplementation could be beneficial to prevent pneumonia, although it has no therapeutic benefit. There is insufficient evidence on potential effectiveness and cost-effectiveness of Hib and Pneumococcal vaccines on reduction of ARI specific mortality. Case-finding and community-based management are effective management strategies, but have low coverage in India due to policy and programmatic barriers. There is a significant gap in the utilization of existing services, provider practices as well as family practices in seeking care. CONCLUSION The systematic review summarizes current evidence on childhood ARI and pneumonia management and provides evidence to inform child health programs in India.

Abstract
BACKGROUND Children in developing country suffer the highest burden of pneumonia. However, few studies have evaluated associations between poverty and pneumonia. METHODS A prospective population-based study on pneumonia was carried out as part of the Latin America Epidemiological Assessment of Pneumococcus (LEAP study). Chest x-rays were obtained for children one to 35 months old with suspected pneumonia presenting to emergency care centers and hospital emergency rooms in Goiania, Brazil. Chest radiographs were evaluated according to WHO guidelines. Clustering of radiologically-confirmed pneumonia were evaluated using a Poisson-based spatial scan statistic. Associations between census socioeconomic indicators and pneumonia incidence rates were analyzed using generalized linear models. RESULTS From May, 2007 to May, 2009, chest radiographs were obtained from 11 521 children with clinical pneumonia; 3955 episodes were classified as radiologically-confirmed. Incidence rates were significantly higher in very low income areas (4825.2 per 105) compared to high income areas (1637.3 per 105). Spatial analysis identified clustering of confirmed pneumonia in Western (RR 1.78; p=0.001) and Southeast (RR 1.46; p=0.001) regions of the city, and clustering of hospitalized pneumonia in the Western region (RR 1.69; p=0.001). Lower income households and illiteracy were associated with pneumonia incidence. CONCLUSIONS In infants the risk of developing pneumonia is inversely associated with the head of household income and with the woman educational level. Areas with deprived socioeconomic conditions had higher incidence of pneumonia and should be targeted for high vaccination coverage.

Abstract
Clinical laboratories providing an etiological diagnosis of respiratory tract infections (RTI) have increasingly relied on nucleic acid amplification tests. Polymerase chain reaction‐based methods are becoming more standardized, and several have undergone the scrutiny of regulatory agencies mandated to assess the risks and benefits of implementing pathogen‐detection assays into diagnostic algorithms. Respiratory viruses lead to both upper and lower RTI and are implicated in exacerbations of chronic pulmonary conditions. Viruses from different taxonomic families present with overlapping clinical signs and symptoms, necessitating an accurate laboratory diagnosis. The clinical utility of diagnostic algorithms incorporating tests for respiratory viruses will depend on the breadth of pathogen coverage and the time to reliable and actionable results. This review covers strategies for detecting a panel of respiratory viruses employed over the last decade that have enabled an etiological diagnosis of RTI in a cost‐effective manner.

Abstract
Infectious disease is the major cause of morbidity and mortality in developing countries, particularly in children. Increasing evidence suggests that protein-calorie malnutrition is the underlying reason for the increased susceptibility to infections observed in these areas. Moreover, certain infectious diseases also cause malnutrition, which can result in a vicious cycle. Malnutrition and bacterial gastrointestinal and respiratory infections represent a serious public health problem. The increased incidence and severity of infections in malnourished children is largely due to the deterioration of immune function; limited production and/or diminished functional capacity of all cellular components of the immune system have been reported in malnutrition. In this review, we analyze the cyclical relationship between malnutrition, immune response dysfunction, increased susceptibility to infectious disease, and metabolic responses that further alter nutritional status. The consequences of malnutrition are diverse and included: increased susceptibility to infection, impaired child development, increased mortality rate and individuals who come to function in suboptimal ways.

Abstract
BACKGROUND As the signs of dehydration often overlap with those of pneumonia, it may be difficult for health workers in resource-poor settings to make a clinical diagnosis of pneumonia in children with dehydration. This issue has received very little attention. AIM To compare the clinical features of pneumonia in children with and without dehydration caused by diarrhoea. METHODS All children aged 2-59 months with diarrhoea and radiologically confirmed pneumonia admitted to the Special Care Ward (SCW) of Dhaka Hospital, ICDDR,B between September and December 2007 were enrolled for the study. Children with dehydration (67 cases) and those without (101 controls) were compared. RESULTS Cases presented less frequently with fast breathing (60% vs 88%, p<0.001) and lower chest-wall indrawing (67% vs 82%, p=0.035) than did controls. In logistic regression analysis, cases more often had severe malnutrition (OR 2.31, CI 1.06-5.02, p=0.035) and cyanosis (OR 19.05, CI 1.94-186.68, p=0.011) and were abnormally sleepy (OR 372, CI 1.71-8.08, p=0.001). CONCLUSIONS Fast breathing and lower chest-wall indrawing may be less reliable for the diagnosis of pneumonia in children with dehydration, especially when there is severe malnutrition.

PLoS Negl Trop Dis 2011; 5:e968. [PMID: 21407802 PMCID: PMC3046969 DOI: 10.1371/journal.pntd.0000968] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2010] [Accepted: 01/20/2011] [Indexed: 12/03/2022] Open
Abstract
Background A wide spectrum of disease severity has been described for Human African Trypanosomiasis (HAT) due to Trypanosoma brucei rhodesiense (T.b. rhodesiense), ranging from chronic disease patterns in southern countries of East Africa to an increase in virulence towards the north. However, only limited data on the clinical presentation of T.b. rhodesiense HAT is available. From 2006-2009 we conducted the first clinical trial program (Impamel III) in T.b. rhodesiense endemic areas of Tanzania and Uganda in accordance with international standards (ICH-GCP). The primary and secondary outcome measures were safety and efficacy of an abridged melarsoprol schedule for treatment of second stage disease. Based on diagnostic findings and clinical examinations at baseline we describe the clinical presentation of T.b. rhodesiense HAT in second stage patients from two distinct geographical settings in East Africa. Methodology/Principal Findings: 138 second stage patients from Tanzania and Uganda were enrolled. Blood samples were collected for diagnosis and molecular identification of the infective trypanosomes, and T.b. rhodesiense infection was confirmed in all trial subjects. Significant differences in diagnostic parameters and clinical signs and symptoms were observed: the median white blood cell (WBC) count in the cerebrospinal fluid (CSF) was significantly higher in Tanzania (134cells/mm3) than in Uganda (20cells/mm3; p<0.0001). Unspecific signs of infection were more commonly seen in Uganda, whereas neurological signs and symptoms specific for HAT dominated the clinical presentation of the disease in Tanzania. Co-infections with malaria and HIV did not influence the clinical presentation nor treatment outcomes in the Tanzanian study population. Conclusions/Significance We describe a different clinical presentation of second stage T.b. rhodesiense HAT in two distinct geographical settings in East Africa. In the ongoing absence of sensitive diagnostic tools and safe drugs to diagnose and treat second stage T.b. rhodesiense HAT an early identification of the disease is essential. A detailed understanding of the clinical presentation of T.b. rhodesiense HAT among health personnel and affected communities is vital, and awareness of regional characteristics, as well as implications of co-infections, can support decision making and differential diagnosis. Sleeping sickness, or Human African Trypanosomiasis (HAT), caused by Trypanosoma brucei rhodesiense is one of the most neglected tropical diseases. It affects mainly rural, poor East African populations and has very high socio-economic impacts. T.b. rhodesiense HAT is an acute disease; patients quickly progress from the first stage, where trypanosomes are detectable in blood and lymph, to the second stage, where parasites penetrate the central nervous system. If left untreated, T.b. rhodesiense HAT is fatal. Disease control is hampered by the absence of sensitive diagnostic tools and safe drugs. Second stage patients can only be treated with melarsoprol, a highly toxic, arsenical drug. It is more difficult to treat patients successfully at advanced stages of the disease, and late onset of treatment should be avoided. Yet, most patients are treated for other conditions prior to HAT diagnosis. Therefore, it is important that health personnel in T.b. rhodesiense endemic regions have a detailed understanding of the clinical presentation of the disease and consider regional characteristics of T.b. rhodesiense HAT for decision making and differential diagnosis.
