Abstract. Background. Studies in developing countries have shown that children with measles have low serum retinol concentrations and that lower retinol levels are associated with measles-related mortality. Vitamin A therapy has been shown to reduce mortality among African children with acute measles. Objectives. To determine whether serum retinol concentration is low among children with measles in the United States and to determine whether retinol concentration is associated with illness severity. Setting. Pediatric referral hospital and clinic in Milwaukee, WI, during the measles outbreak of 1989-1990. Patients. One hundred fourteen patients less than or equal to 5 years of age evaluated for serologically confirmed measles with serum obtained within 5 days following rash onset. Methods. Serum retinol concentration was determined by high-performance liquid chromatography. Clinical data were collected by hospital record review, A modified Pediatric Risk of Mortality (PRISM) score was used to assess physiologic instability as a measure of illness severity; Results. Retinol concentrations ranged from 0.25 to 1.718 micro mol L (median 0.58 micro mol/L); 82 (72%) patients had low retinol concentration (less than or equal to 0.70 micro mol/L). Median retinol concentrations were lower among hospitalized patients (0.56 vs 0.70, P = .006) and patients with pneumonia (0.52 vs 0.64, P = .02) but higher among children with otitis media (0.63 vs 0.54, P = .01). Higher modified PRISM scores, reflecting greater physiologic instability were associated with lower retinol concentration (beta coefficient -.0147, P = .025). In multivariate analysis, higher modified PRISM scores were associated with lower retinol concentration (beta coefficient... [ABSTRACT FROM AUTHOR]
