Acute splenic sequestration crisis in adults with hemoglobin S-C disease: a report of nine cases



Acute splenic sequestration crisis (ASSC) is a potentially life-threatening complication and one of the leading causes of death in children with sickle cell disease. It is rarely reported in adults with hemoglobin S-C disease and its natural history in these patients has not been well studied. We describe here the clinicopathological features of ASSC in nine adults with hemoglobin S-C disease treated between 1972 and 2000 and followed for a mean period of 9 years (range 0–21 years). ASSC was characterized by acute left upper quadrant abdominal pain, splenomegaly, fever, and a rapid decrease in hematocrit with active erythropoiesis. The hemoglobin decreased by a mean of 4.8 g/dl from the steady state value (range 3.0 to 6.7 g/dl) during ASSC. Two patients failed to respond to transfusion of packed erythrocytes and required urgent splenectomy. There was one fatality—a 76-year-old woman, who died 36 h after admission. There was no recurrence of ASSC in five patients followed for 2, 3, 16, 18, and 21 years, respectively. ASSC in adults is a serious and occasionally, fatal complication of hemoglobin S-C disease. Patients with hemoglobin S-C disease may remain at risk of ASSC into their eighth decade.
