[Safety of treatment with tacrolimus ointment for anterior segment inflammatory diseases]. / Sicherheit der Behandlung entzündlicher Vorderabschnittserkrankungen mit Tacrolimus-Salbe.

BACKGROUND: The off-label use of topical tacrolimus (Protopic) for inflammatory external eye diseases is gaining popularity. However, there are no reports on the safety profile of this new treatment option. PATIENTS AND METHODS: We treated six patients with different inflammatory eye diseases with topical tacrolimus (Protopic 0.03 %) as off-label use in addition to the conventional anti-inflammatory treatment. Patients were interviewed for side effects and serum drug concentrations were measured under steady state conditions one hour after topical application of tacrolimus ointment. RESULTS: Two patients reported a slight burning sensation immediately after application, in one patient we found a slight worsening of the dry eye problems. No patient abandoned the treatment due to side effects. Serum drug concentrations remained below the analytical threshold in all cases (< 1.5 ng/ml). CONCLUSIONS: Tacrolimus for the topical treatment of anterior segment inflammatory eye diseases is well tolerated without detectable systemic drug resorption.

Selection bias of elderly patients with chronic angina referred for catheterization.

BACKGROUND: Registry patients are generally older and more sick than patients enrolled in trials questioning the generalizability of trial results. We assessed whether such a selection bias also exists in elderly patients with chronic angina referred for catheterization. METHODS AND RESULTS: All 119 patients age>or=75 years with Trial of Invasive versus Medical Therapy in the Elderly (TIME) inclusion but no major exclusion criteria referred for catheterization during the TIME trial inclusion period in four TIME centers were registered and followed-up for one year. Registry patients differed from the 188 trial patients in the same hospitals in that they were younger, somewhat more frequently male, with less antianginal drugs and studied more often after acute chest pain at rest but with more comorbidities than study patients. Left ventricular ejection fraction and vessel disease were similar. One year mortality was 11.4% in registry and 9.6% in invasive TIME patients but differences disappeared after adjustment for baseline differences. Symptomatic status after one year was similar too. CONCLUSIONS: In elderly patients with chronic angina, a bias in the selection for invasive management exists which seems different from that reported in younger patient settings. After adjustment for these selection factors, however, one-year outcome was remarkably similar in registry and trial patients.
