title: [Significance of hereditary factors in multiple organ dysfunction syndrome in children with infections].
abstract: In order to elucidate the contribution of hereditary factor (dose of ribosome genes) to the realization of organ dysfunction syndromes in children with surgical infection, the total size of silver nitrate-stained nucleoli-forming regions (Ag-NFR) of acrocentric chromosomes in karyotypes was assessed in 22 patients aged from 14 months to 12 years, 17 of these with appendicular peritonitis, 4 with destructive pneumonia, and 1 with acute hematogenic osteomyelitis. Pyoseptic diseases involved no organ dysfunction in 10 patients, and in 12, multiple organ dysfunction was diagnosed. Our findings indicate that the carriers of low-copy variants of ribosome genes are characterized by hereditary predisposition to lowered individual resistance of the organism. Therefore, children with surgical infection with a decreased size of Ag-NFR (low dose of ribosome genes) in the karyotype potentially represent a group at risk of multiple organ dysfunction realization.
