Smoking is a factor in causing acute chest syndrome in sickle cell anemia.
A link between cigarette smoking and "acute chest syndrome" in sickle cell anemia is suggested. Acute chest syndrome in the patient with sickle cell anemia is characterized by fever, leukocytosis, cough, chest pain, and pulmonary infiltrates in the chest radiograph. This article describes the results of a study of 69 adolescent and young adult sickle cell anemia patients. Twenty-nine of these patients were smokers, three were former smokers, and 37 were nonsmokers. Patients completed respiratory questionnaires that focused on smoking habits and included a history of chest syndrome. Information obtained was confirmed by review of clinical records. The chi-square test demonstrated a strong relationship between cigarette smoking and chest syndrome in sickle cell anemia. All 29 smokers had a history of chest syndrome, but only 24 of 37 nonsmokers had such a history. Although the exact mechanism of the relationship between smoking and the development of acute chest syndrome remains speculative, cigarette smoking joins infection, hypoxia, acidosis, infarction, dehydration, and analgesics as a causative factor in adolescent and adult patients with sickle cell anemia. Behavioral modification of the smoking habit in patients with sickle cell anemia may decrease the frequency of acute chest syndrome and sequelae of sickle cell lung disease.
