Sonographic Screening for Abdominal Organ Involvement in Sickle Cell AnemiaA Step towards Better Patient Care

Abstract

Background: Sickle cell disease is characterized by repeated crisis and need for frequent transfusions. Abdominal crisis are common and potentially can damage any abdominal organ. Screening for organ involvement will lead to early detection and better patient care. Aim and Objectives: To see whether ultrasound can be a better noninvasive technique for early detection of organ involvement. Material and Methods: Prospective cross sectional observational study done on patients admitted in pediatric ward of a medical college. Total of 150 patients, already diagnosed to have sickle cell anemia (homozygous 110 and heterozygous 40) was included in the study. All the patients were in steady state. Demographic, clinical biochemical details were noted and were subjected to ultrasonography. Renal artery, Being end artery, Doppler study was also done. All the modalities were compared for early detection. Results: Majority of patients (77%) were between 1 to 30 years with male female ratio of 2:1. Recurrent fever (64%) and recurrent abdominal pain (47%) were most common symptoms and anemia (66%), hepatomegaly (62%), splenomegaly (21%) were most common signs. When clinical examination, biochemical tests and ultrasonography were compared for organ detection, ultrasound significantly detected more patients (p=<0.05). Ultrasonography of kidney included renal doppler also. Renal involvement by microalbuminuria measurement was of same as ultrasonography. Organ involvement increased with age. Conclusion: Ultrasonography was good noninvasive technique for organ detection but kidneysyield was better with Doppler study. Most common organ found to be affected was liver. Involvement increased with age. Early detection helps clinicians to avoid drugs toxic to involved organs.
