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.

Age specific fast breathing in under-five diarrheal children in an urban hospital: Acidosis or pneumonia?

BACKGROUND: Children with diarrhea often present with fast breathing due to metabolic acidosis from dehydration. On the other hand, age specific fast breathing is the cornerstone for the diagnosis of pneumonia following classification of pneumonia recommended by the World Health Organization (WHO). Correction of metabolic acidosis by rehydrating the diarrheal children requires time, which delays early initiation of appropriate antimicrobials for pneumonia and thereby increases the risk of deaths. We need to further investigate the simple clinical features other than fast breathing which might help us in earliest diagnosis of pneumonia in children with diarrhea Thus, the objective of our study was to identify other contributing clinical features that may independently help for early diagnosis of pneumonia in diarrheal children who present with age specific fast breathing. METHODS: This was an unmatched case-control study. Diarrheal children aged 0-59 months, admitted to Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b) during January 2014 to December 2014 having age specific fast breathing (<2 month ≥60 breath/min, 2-11 months ≥50 breaths/min, >11-59 months ≥40 breaths/min) were studied. The study children with clinical and radiological pneumonia constituted the cases (n = 276) and those without pneumonia constituted the controls (n = 446). Comparison of clinical features and outcomes between the cases and the controls was made. RESULTS: The distribution of acidosis among the cases and the controls was comparable (35% vs. 41%, p = 0.12). The cases had proportionately higher deaths compared to the controls, however, the difference was not statistically significant (3% vs. 1%; p = 0.23). In logistic regression analysis after adjusting for potential confounders, the cases were independently associated with cough (OR = 62.19, 95% CI = 27.79-139.19; p<0.01) and chest wall indrawing (OR = 31.05, 95%CI = 13.43-71.82; p<0.01) and less often had severe acute malnutrition (OR = 0.33, 95%CI = 0.13-0.79; p<0.01). The sensitivity and specificity of cough were 83% (78-87%) and 93% (91-96%). The sensitivity and specificity for lower chest wall indrawing were 65% (59-71%) and 95% (93-97%). However, the sensitivity and specificity of cough and lower chest wall indrawing combined were 94% (89-97%) and 99% (97-100%). CONCLUSION AND SIGNIFICANCE: Thus, diarrheal children having fast breathing who present with cough and/or lower chest wall indrawing, irrespective of presence or absence of metabolic acidosis, are more likely to have radiological pneumonia. The results underscore the importance of early identification of these simple clinical features that may help to minimize potential delay due to rehydration in initiating prompt treatment of pneumonia in order to reduce fatal consequences in such children.

Clinical profile of hospitalized HIV-infected children in Bangladesh, a low-HIV-prevalence country.

BACKGROUND: Bangladesh has a low HIV prevalence and data on the risk factors and clinical presentation of HIV-infected children are lacking. OBJECTIVE: To describe the clinical characteristics of hospitalized HIV-infected children in Bangladesh and determine the factors associated with a low CD4 count. METHODS: An anonymous, retrospective review was undertaken of the medical records of all patients admitted to the HIV unit of the iccdr,b Dhaka Hospital between February 2009 and July 2012. Demographic, clinical and laboratory data were extracted from the electronic medical record system. HIV-infected children with a low absolute CD4 count (<200 cells/µl) were compared with HIV-infected children with a CD4 count ≧200 cells/µl. RESULTS: Of 266 HIV-infected patients, 24 were children (9%), 13 (54%) of whom were male. Ages ranged from 2 to 17 years (median 7). Of the 21 (88%) children who acquired the infection by vertical transmission, median age at diagnosis was 5·2 years, and the parents of 19 (79%) reported a history of external migration. Children commonly presented with prolonged fever (n = 14, 58%), recurrent cough (n = 14, 58%), failure to thrive (n = 11, 46%) and recurrent diarrhoea (n = 4, 17%). Six (25%) patients had tuberculosis, four (16·7%) had herpes zoster and four (16·7%) were diagnosed with Pneumocystis jirovecii pneumonia. One child died during hospitalization. Children with a low CD4 count (<200 cells/µl) more often had severe wasting (95% CI 1·2-453·97) and severe under-nutrition (95% CI 1·39-196·25) than those with a higher CD4 count*. CONCLUSION: The majority of HIV-infected children presenting to an inpatient speciality ward in Dhaka acquired HIV through vertical transmission, and most of the parents had a history of external migration. Further studies are needed to determine the optimal strategy for preventing mother-to-child transmission and for early identification and treatment of HIV-infected children in this low-prevalence country.
