Abstract
BACKGROUND: A relatively young man (43 years old) was found to have a cataract after receiving prednisone before each of 35 neutrophil (PMN) donations over several years. Because corticosteroids are known to induce posterior subcapsular cataracts (PSCs), additional repeat PMN donors were examined ophthalmologically. STUDY DESIGN AND METHODS: A controlled, blinded study was performed in 11 PMN donors who received prednisone with or without G-CSF before 17 to 46 leukapheresis donations over an average of 8.5 years. Control subjects were nine plateletpheresis donors of comparable age and donation experience, but they had never donated PMNs. A complete eye examination was performed by an ophthalmologist who was unaware of the donor's status (PMN vs. platelet). RESULTS: Mild PSCs were found in 36 percent (4/11) of PMN donors versus 0 of 9 platelet donors (p = 0.068). Five of the 22 PMN donor eyes involved versus 0 of the 18 platelet donor eyes involved exhibited PSCs (p = 0.040). Cortical and nuclear cataracts were found similarly in both groups of donors (82% PMN vs. 56% platelet donors; p = 0.217); this indicated that lifestyle factors, independent of corticosteroids, that might predispose to cataract formation probably were comparable. CONCLUSION: Corticosteroids given before PMN donations by leukapheresis might increase the risk of PSCs. Because of widespread renewed interest in PMN transfusions, this potential risk factor--if confirmed by studies of additional PMN donors--is of great international importance. Other centers are urged to perform ophthalmologic examinations on repeat PMN donors to clarify this issue.
