BACKGROUND & AIMS: Whipple's disease is a chronic infection caused by the actinomycete Tropheryma whipplei. We conducted a randomized controlled trial of the efficacy of antimicrobials that are able to cross the blood-brain barrier and to which T whipplei is susceptible. METHODS: Patients from central Europe with previously untreated Whipple's disease (n = 40) were assigned randomly to groups given daily infusions of either ceftriaxone (1 x 2 g, 20 patients) or meropenem (3 x 1 g, 20 patients) for 14 days, followed by oral trimethoprim-sulfamethoxazole for 12 months. The primary outcome measured was maintenance of remission for 3 years, determined by a composite index of clinical and laboratory data as well as histology. RESULTS: All patients were observed for the entire follow-up period (median, 89 mo; range, 71-128 mo); all achieved clinical and laboratory remission. Remission was maintained in all patients during the time of observation, except for 2 who died from unrelated causes. A single patient with asymptomatic cerebrospinal infection who was resistant to both treatments responded to chloroquine and minocycline. The odds ratio for the end point (remission for at least 3 years) was 0.95 (95% confidence interval, 0.05-16.29; P = 1.0). CONCLUSIONS: This was a randomized controlled trial to show that treatment with ceftriaxone or meropenem, followed by trimethoprim-sulfamethoxazole, cures patients with Whipple's disease. One asymptomatic individual with infection of the cerebrospinal fluid required additional therapy.
