Host Factors and Acute Lower Respiratory Infections in Pre-school Children

Abstract

The relationship between certain host-related variables and the short-term outcome of hospitalization for severe acute lower respiratory infections was studied prospectively in a cohort of 103 pre-school Nigerian children. The respective mean ages of those with bronchiolitis and croup were 3.2 months and 18.9 months while the corresponding M:F ratios were 2.5:1 and 1:1. It was highly significant that all the eight children that died were malnourished (P less than 0.01). Furthermore, malnourished subjects with pleural effusion, in whom bacteraemia was common, stayed longest in hospital while subjects with bronchiolitis and croup, in whom malnutrition was distinctly uncommon, had the shortest duration of admission. Multiple microbial identifications and bacteraemia were common in malnourished subjects with ALRI. Mortality was significantly higher in older children (P less than 0.05), but sex, immunization/breast-feeding status and co-existing measles or pertussis, were individually neither related to the admission outcome nor the duration. It is concluded that malnutrition is a strong predictor of ALRI-related death in the pre-school child. The significance of bacteraemia and multiple microbial identifications in malnourished children, and the ARI-control implications of the study are discussed.

Pneumonia in severely malnourished children in developing countries – mortality risk, aetiology and validity of WHO clinical signs: a systematic review

“…The majority of studies included a relatively small number of severely malnourished children with only five of the studies including more than 50 patients. Six studies used blood cultures alone to identify the causative organism (Berkowitz 1983; Friedland 1992; Johnson et al . 1992, 1993; Shimeles & Lulseged 1994; M.J. Chisti, unpublished data), four used lung aspirates alone (Hughes et al .…”

Global Patterns of Child Health: The Role of Nutrition

“…In the former, frequency, duration and severity have all been correlated with nutritional status in several prospective studies [6][7][8][9][10][11]. Undernutrition has also been shown to increase the severity of respiratory infections, particularly in younger children [12].…”

Risk Factors of Mortality in Acute Lower Respiratory Tract Infections in Children (1 Month to 5 Years)

“…Deivanayagam et al [10] and Nathoo et al [14] had found age under 6 month Johnson et al [15] interestingly, reported higher mortality in children above 12 months of age s to be significant.…”
