      Abstract

      OBJETIVO: Avaliar parâmetros nutricionais no prognóstico de adultos internados em hospital geral, com pneumonia adquirida na comunidade. MÉTODOS: Foram estudados prospectivamente 61 casos da doença e analisadas variáveis: sociodemográficas, morbidade, hábitos de vida, antropométricas (índice de massa corporal, circunferência da cintura, porcentagem de gordura, porcentagem de perda de peso), bioquímicas (ureia, creatinina, albumina no momento da internação e no 18º dia e pré-albumina (na internação, quarto, oitavo e 18º dia) e evolução (menos de 10, mais de 10 dias de internação e/ou óbito). RESULTADOS: As variáveis antropométricas apresentaram-se diferentes entre os sexos, porém não se associaram com a má evolução da doença. Os níveis séricos de albumina e de pré-albumina encontraram-se baixos na internação em 80,3% e 86,9% dos casos, respectivamente. Após ajuste logístico, o hábito de fumar (OR:1,23, IC:1,0-12,1), a presença de mais de uma imagem ou derrame pleural no exame radiológico de tórax (OR: 1,4 IC: 1,24-15,3) e a pré-albumina baixa no quarto dia (OR:6,1 IC:1,7-22,5) foram preditores de má evolução do quadro de pacientes com pneumonia adquirida na comunidade. CONCLUSÃO: Indicador bioquímico nutricional como a pré-albumina, o tabagismo e mais de uma imagem no exame radiológico de tórax são parâmetros de gravidade de pneumonia úteis na condução clínica de infecções.

      OBJECTIVE: The present study assessed the influence of nutritional parameters on the prognosis of community-acquired pneumonia in adults admitted to a general hospital. METHODS: A total of 61 individuals with community-acquired pneumonia were studied prospectively and the following data analyzed: sociodemographic variables, morbidity, life habits, anthropometric variables (body mass index, waist circumference, percentage of body fat, percentage of weight lost), biochemical variables (urea, creatinine, albumin on admission and 18 days later, prealbumin on admission and 4, 8 and 18 days later), and outcome (hospital stay shorter than 10 days, longer than 10 days and/or death). RESULTS: Anthropometric variables differed between genders but were not associated with poor outcome. Albumin and prealbumin levels were low on admission in 80.3% and 86.9% of the cases, respectively. Logistic regression showed that smoking (OR:1.23; CI:1.0-12.1), more than one finding or pleural effusion on chest radiographs (OR:1.4; CI:1.24-15.3) and low prealbumin on day 4 (OR:6.1; CI:1.7-22.5) predicted a poor outcome for patients with community-acquired pneumonia. CONCLUSION: Nutrition-related biochemical markers, such as low prealbumin, smoking and more than one finding on chest radiographs, indicate severe pneumonia and are useful for deciding treatment strategy.

        The interaction between nutrition and infection.

        Infection and malnutrition have always been intricately linked. Malnutrition is the primary cause of immunodeficiency worldwide, and we are learning more and more about the pathogenesis of this interaction. Five infectious diseases account for more than one-half of all deaths in children aged <5 years, most of whom are undernourished. Micronutrient deficiencies have effects such as poor growth, impaired intellect, and increased mortality and susceptibility to infection. The worldwide magnitude of parasite infection is enormous. It is understood that parasites may lead to malnutrition, but the extent to which malnutrition causes increased parasite infestation is not known; thus, the conditions need to be addressed together. Nutritional deficiencies associated with pregnancy are associated with poor immune response to infection. Because this immune deficiency is partially compensated by breast-feeding, this is the single best way to protect infants from infection. Malnutrition and nutritional alterations, common complications of human immunodeficiency virus infection, include disorders of food intake, nutrient absorption, and intermediary metabolism and play a significant and independent role in morbidity and mortality. The 21st century provides new information and new challenges. With new technologies and political changes, it is hoped that a healthier, more disease-free, and better-nourished population will emerge.
