RESUMO

PURPOSE: This study describes the central nervous system (CNS) events after lung transplantation. METHODS: A chart review of all lung transplant recipients (LTR) to collect the clinical and neuroimaging data for CNS events defined as seizures, severe headaches, confusion, or stroke. RESULTS: Twenty-six patients of 100 LTRs from 1990 through 1995 had a CNS event; more than one event occurred in 5 patients for a total of 32 events. Severe headache was most common, occurring in 14 patients, followed by seizures in 10, stroke in 5, and confusion in 3. The CNS event was related to infection in three of the 26 patients. Of all evaluations performed, magnetic resonance imaging (MRI) identified the most abnormalities, the most common being white matter changes consistent with cyclosporine toxicity. Cyclosporine levels were elevated in slightly more than half of the patients. Hypomagnesemia was present in three of 10 patients with seizures. Prognosis for recovery from these complications was good, with only five patients having ongoing problems with headaches, one requiring long term anticonvulsant therapy, three having minor or no limitations from stroke and no long-term problems with confusion. One patient with seizures resulting from an aspergilloma died. CONCLUSION: CNS events occur commonly in LTRs, mostly related to cyclosporine toxicity or infection. MRI identifies more abnormalities than computed tomography. These events were not consistently associated with documented high cyclosporine levels and hypomagnesemia. In spite of significantly abnormal MRIs, the functional outcome is favorable.

RESUMO

Central nervous system (CNS) complications occur more frequently in cystic fibrosis (CF) patients than other lung transplant recipients. The purpose of this study was to compare CF patients with and without CNS complications following lung transplantation, to identify risk factors for CNS events. Records of 21 patients with CF who underwent lung transplant between 1991-1996 were reviewed. Data were collected on multiple variables, including: age at transplant; gender; cytomegalovirus (CMV) status; cholesterol and triglyceride levels; sinusitis; percent ideal body weight (IBW); body mass index (BMI); augmented immunosuppression, acute lung rejection episodes (ALR); cyclosporine doses; electrolytes; magnesium, blood urea nitrogen (BUN), and creatinine levels; and 6-month survival. CNS complications identified were seizures, severe headaches (HA), strokes, or confusional episodes. Eleven of 21 patients (52%) with CF had CNS events: eight had seizures, five HA, three strokes, and one confusional episode. There was no difference in age at transplant, pretransplant percent IBW or BMI, cholesterol and triglyceride levels, or number of ALR. CMV mismatch and clinical sinusitis had no effect. Cyclosporine doses did not differ between groups at 30 days, or 3 or 6 months posttransplant. Both BUN and creatinine concentrations showed a rise over time that did not differ between groups. Potassium levels were within normal limits for both groups. While sodium levels did not differ between groups pretransplant, or at 30 days or 6 months posttransplant, a decrease in sodium values was seen at the time of CNS events. There was no difference in 6-month survival. We could not identify any pre- or posttransplant risk factors that predicted CNS events. It is likely that cyclosporine toxicity is the major cause of CNS complications. Despite the high rate of CNS events, the overall prognosis was good, and 6-month survival was not affected.
