Abstract

Bone marrow biopsies from the iliac crest in 56 patients with chronic pyelonephritis were evaluated quantitively and correlated with renal function and peripheral blood values (n = 100). In proportion to increasing serum creatinine, mild marrow hypoplasia develops which mainly, and to a statistically significant extent, affects the percentage and amount of erythropoietic cells and megakaryocytes. The simultaneous reduction of erythrocytes and reticulocytes in peripheral blood is more pronounced and only slightly correlated to the marrow cells. There is no correlation between the number of peripheral granulocytes or the decrease in lymphocytes concomitant with uremia, and their respective precursors in the marrow.
