چکیده
OBJECTIVE The aim of this study was to examine the plasma retinol of children in the acute phase of pneumonia and after recovery and to investigate the association between plasma levels of retinol after recovery with socioeconomic variables, nutritional status and severity of pneumonia. METHODS A prospective cohort study which included 40 low-income hospitalized children with pneumonia, aged 6 months to 5 years. We evaluated: plasma retinol level during the acute phase and after recovery, years of schooling of the head of the family, per capita income, birth weight, nutritional status, hemoglobin levels and severity of pneumonia. RESULTS Mean plasma retinol levels were significantly higher after recovery than during the acute phase of infection (1.4+/-0.6 vs. 1.7+/-0.6 micromol/l, p = 0.03). The frequency of inadequate plasma retinol levels (< 1.05 micromol/l) was 32.5 and 17.5% for the acute phase and after recovery, respectively. There were no statistically significant associations between plasma retinol deficiency and the clinical and epidemiological variables studied. More severe pneumonia was observed in 30/40 (75%) of the patients. There was no statistically significant association between plasma retinol inadequacy after recovery and severity of pneumonia (4/30 - 13.3% vs. 3/10 - 30.0%, p = 0.34). CONCLUSION Serum retinol levels were significantly higher after recovery than during the acute phase of pneumonia. There was no statistically significant association between the deficiency of serum retinol and the clinical and epidemiological variables studied.

OBJECTIVE To compare serum retinol levels in preschool children during an episode of pneumonia and 45 days after the resolution of the infection. METHODS The study was conducted with preschool children without any infection (control group, n = 9) or children hospitalized for pneumonia (n = 12), who were evaluated soon after hospitalization (phase 1) and 45 days later (phase 2).

متن کاملThe Effect of Food Deprivation on Nociception in Formalin Test and Plasma Levels of Noradrenaline and Corticosterone in Rats
Introduction: The concentration of noradrenalin and corticosterone as the two nociception modulators change after fasting or stress situation. The aim of present study was to investigate the effect of food deprivation on formalin-induced nociceptive behaviours and plasma levels of noradrenalin and corticosterone in rats. Methods: Food was withdrawn 12, 24 and 48 h prior to performing the formal...
متن کاملVitamin C Prevents Sleep Deprivation-induced Elevation in Cortisol and Lipid Peroxidation in the Rat Plasma.
Sleep deprivation (SD) is biological stressor that alters metabolic parameters, induced oxidative stress and lipid peroxidation. Previous studies have shown that antioxidants substances such as melatonin, tryptophan, vitamin E and vitamin C improved stress tolerance in laboratory animals. In this study, we examined the potential protective effects of administration of vitamin C on acute and chr...
متن کامل25-Hydroxy-Vitamin D Concentration Is Not Affected by Severe or Non-Severe Pneumonia, or Inflammation, in Young Children
Poor vitamin D status has been associated with increased risk and severity of respiratory tract infections. Whether or not inflammation and infection affects 25-hydroxy vitamin D (25(OH)D) concentration is controversial and is important in the interpretation of observational studies using plasma-25(OH)D as a biomarker for status. Our objectives were to measure whether 25(OH)D concentration was ...
متن کاملSerum levels of vitamins A and D, and zinc in children with acute diarrhea: A cross-sectional study
Background: Diarrhea is a leading cause of mortality and morbidity during the early life period especially in developing countries. Micronutrients deficiencies have been proposed either as a risk factor or a consequence of diarrhea. Association studies highlight the relation of vitamins and minerals’ deficiencies with acute diarrhea. In this regard we aimed to evaluate the status of vitamins ...
