title: [Seasonal dynamics of the indices of humoral immunity in children aged 3 months to 1 year in relation to nutrition in an arid zone].
abstract: The paper reports seasonal data on humoral immunity of 245 Turkmen and 240 European infants aged 3-12 months. Allowances were made for climatic conditions of the arid zone and essential feeding. In summer there were reduced levels of IgM, IgG in the serum and insufficient supply with thiamine and ascorbic acid. IgA serum level was the lowest in spring. IgA strongly correlated (r = 0.7-0.8) with thiamine and ascorbic acid intake in spring, IgM and IgG with retinol and thiamine in summer. The above changes in humoral immunity in summer are associated with growing incidence of intestinal diseases and lower body mass in the infants in the condition of arid zone.
