[Clinical Characteristics of Drug Hypersensitivity Syndrome in 10 Patients].

OBJECTIVE:To characterize the clinical characteristics of drug hypersensitivity syndrome (DHS).METHODS:The clinical characteristics of 10 DHS patients admitted into our hospital were analyzed retrospectively. And the occurrence patterns of DHS were summarized.RESULTS:There were 4 males and 6 females with an age range of 17 to 66 years. Suspected drugs were anticonvulsants (n = 5), allopurinol (n = 2), antibiotics (n = 1), acetaminophen (n = 1) and unknown (n = 1). All cases developed skin rashes with fever within 14 to 60 days (n = 10). Lymphadenopathy was observed (n = 6). Morbilliform eruption was most common skin rash (n = 6); facial swelling was also appeared (n = 7). Eosinophilia was observed in all cases (n = 10). Liver involvement was common (n = 9). Autoimmune antibodies abnormality was uncommon; viral infection was complication in several cases. Glucocorticoids were applied in all cases (n = 10), 3 severe cases were administrated with intravenous immunoglobulin (IVIg). The clinical outcomes included discharging with recovery (n = 7), later diagnosed of non-Hodgkin lymphoma (n = 2) and in-hospital death (n = 1).CONCLUSIONS:The clinical manifestations of DHS are complicated. And the common reactive drugs include anticonvulsants, allopurinol, antiinflammatory drugs and antibiotics. Some cases may be misdiagnosed and long-term follow-ups are required.
