    Abstract:
    BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare disease which can cause severe morbidity and mortality. The aim of this study is to evaluate the clinical manifestation and course of DRESS syndrome. METHODS: We conducted a retrospective analysis of prospectively collected data in 45 patients with DRESS syndrome diagnosed between September 2009 and August 2011. RESULTS: The most common causative drug group was antibiotics (n=13, 28.9%), followed by anticonvulsants (n=12, 26.7%), antituberculosis drugs (n=6, 13.3%), non-steroidal anti-inflammatory drugs (n=4, 8.9%), undetermined agents (n=4, 8.9%), allopurinol (n=3, 6.7%), and others (n=3, 6.7%). The latency period ranged from 2 to 120 days, with a mean of 20.2 ± 24.3 days. The longest latency period was noted for the antituberculosis drug group, at 46.5 ± 29.9 days. Eosinophilia in peripheral blood examination was noted in 35 subjects (77.8%). Atypical lymphocytosis was noted in 16 patients (35.6%), and thrombocytopenia in seven patients (15.6%). Hepatic involvement was noted in 39 (86.7%) study patients, kidney in eight (17.8%), lung in four (8.9%), and central nervous system in one (2.3%). Systemic corticosteroids were administered to 10 patients (22.2%). Forty-three patients (95.6%) showed complete recovery, while two patients had poor outcomes. CONCLUSIONS: DRESS syndrome was not more uncommon than generally recognised. Antibiotics were the most frequently implicated drug group, followed by anticonvulsants. Most patients with this disease showed a better clinical outcome than that which had been generally expected.
