Abstract
O presente estudo teve como objetivo o registro e a apresentação de trabalhos realizados no Brasil nos últimos 40 anos, relacionados com a investigação sobre a deficiência de vitamina A. Esta deficiência tem sido diagnosticada por um ou mais dos seguintes critérios: ingestão deficiente de alimentos fontes de vitamina A, exame clínico, níveis séricos de retinol abaixo dos aceitos como normais, concentração hepática de retinol, teste de adaptação ao escuro e corante de Rosa Bengala. A deficiência foi diagnosticada em grupos populacionais de vários Estados e capitais brasileiras em cidades grandes e pequenas e em zonas rurais. A maioria dos trabalhos foi desenvolvida em grupos populacionais de baixa renda. Quanto às conseqüências clínicas, relataram-se achados de sinais oculares leves, como cegueira noturna, manchas de Bitot e xerose conjuntival, encontrados principalmente na Região Nordeste. Alguns autores observaram, em menor número de casos, lesões graves, como lesões corneanas e ceratomalácia. Trabalhos da última década indicaram associação entre a hipovitaminose A e o aumento da morbidade e mortalidade, principalmente em crianças pré-escolares.
This work presents a review of investigations carried out in Brazil in the last 40 years, concerning the diagnosis of hypovitaminosis A. Vitamin A deficiency has been established by means of dietary intake, clinical signs, low serum and hepatic retinol concentrations, and by the rose bengal staining test and rapid dark-adaptation test. The vitamin deficiency has been found in many Brazilian, in many states capitals, in big and small cities and also in rural areas. Most of the research work has been undertaken with samples of populations of low socioeconomic level. As far as clinical signs are concerned, eye signs indicative of xerophtalmia were found mainly in the Northeastern Region. They included night blindness and conjunctival xerosis with or without Bitot's spots. More severe lesions such as irreversible changes or keratomalacia were rarely observed. Recent papers have shown the relationship between vitamin A deficiency and the increase in morbidity and mortality, mainly in pre-school children.
