Abstract BACKGROUND: The systemic capillary leak syndrome is a rare idiopathic disorder characterized by recurrent episodes of hypotension and hemoconcentration due to sudden transient extravasation of 10\% to 70\% of plasma. Mortality rates 5 years after diagnosis have been reported to be 76\%. OBJECTIVE: To assess the efficacy of a prophylactic regimen for the systemic capillary leak syndrome. DESIGN: Case series. SETTING: Tertiary referral center. PATIENTS: Eight patients followed over the past 18 years. INTERVENTION: Oral terbutaline plus aminophylline or theophylline. MEASUREMENTS: Long-term clinical follow-up. RESULTS: During a median follow-up of 9 years (range, 2 to 18 years), two patients (25\%) died: one during an acute episode and one of complications related to long-term corticosteroid therapy. The other six patients are alive and healthy. The frequency and severity of the episodes decreased by a median of 30-fold. Recurrences were associated with decreased serum theophylline levels, possibly caused by enzyme induction or autoinduction. The extended-release form of medication was more successful. Sympathomimetic side effects were significant. CONCLUSIONS: A regimen of terbutaline and theophylline seems to be effective prophylaxis against the systemic capillary leak syndrome. Maintenance of therapeutic drug levels was associated with favorable results.
