RESUMEN
We estimated the percentage of CD4+ lymphocytes synthesizing IFN-gamma and IL-4 in the peripheral blood and measured the concentrations of IL-1, IL-6, and TNF-alpha in lochia of patients with postpartum endometritis. T lymphocytes with intracellular IFN-gamma prevailed in women with physiological course of the postpartum period. The number of cells containing IL-4 increased in patients with postpartum endometritis. On days 5-7 after childbirth the concentrations of proinflammatory cytokines IL-1beta and TNF-alpha in lochia of these patients were higher than in healthy postpartum women (by 1.4 and 2.7 times, respectively). The concentrations of cytokines IL-1beta, TNF-alpha, and IL-6 increased most significantly in patients with postpartum endometritis and active viral infection (by 3.4, 4.2, and 1.6 times, respectively).
