Sickle cell disease-related organ damage occurs irrespective of pain rate: implications for clinical practice

In daily clinical practice, the frequency of painful crises (pain rate) is an important parameter of sickle cell disease severity. We assessed the prevalence of sickle cell disease-related organ damage and complications and their relation to pain rate. Organ damage and history of vaso-occlusive complications were obtained via systematic screening of consecutive patients and by chart review. In 104 adult sickle cell patients pain rate was related to a history of acute chest syndromes, avascular osteonecrosis, iron overload, priapism and cholelithiasis. However, major disease-related complications, such as microalbuminuria and pulmonary hypertension, were detected in 23% and 24% respectively of patients without painful crises in the study period underlining the importance of systematic screening for developing organ damage in sickle cell patients irrespective of pain rat
