Acute events in hospitalized patients with sickle cell anemia before and after the use of hydroxyurea
International Archives of Medicine
Objective: To estimate the occurrence of acute events in hospitalized patients with sickle cell anemia (SCA) before and after the use of hydroxyurea (HU). Method: The study has a quantitative approach, of analytical cohort type developed in two public referral hospitals in the Midwest region of Brazil Results: The sample had 32 medical records of hospitalized patients diagnosed with SCA who used HU. The mean age of the participants was 25.65±11.92; the average time of drug exposure was 6.0±2.8
... posure was 6.0±2.8 years; the average initial dose was 17.00±5.3mg/kg/day and final dose of 22.10±5.3 mg/kg/day. After using HU, the fetal hemoglobin ranged from 8.41±0.95 to 14.44±13.7% (p<0.001). There was a reduction of the average leucocyte, absolute neutrophil, acute events, total infections and blood transfusions. Conclusion: The effects of HU exposure caused an increase in fetal hemoglobin level, decreasing leukocyte, absolute neutrophils and acute events, transfusions and hospitalizations by the use of non-opioid.
