A 3‐month‐old girl with Sturge‐Weber syndrome presented with a morbilliform rash, eosinophilia, and fulminant liver failure to our tertiary pediatric hospital. She was diagnosed with drug reaction with eosinophilia and systemic symptoms complicated by viremia and evidence of viral hepatitis on liver biopsy. We discuss the role of viral reactivation in drug reaction with eosinophilia and systemic symptoms and the relevance of antiviral therapy in management.  相似文献

Lymphadenopathy is a common sign for drug reaction and eosinophilia with systemic symptoms (DRESS) syndrome, but hilar and mediastinal lymphadenopathy may be underreported. We describe a 7‐year‐old boy who started taking ethosuximide for absence seizures and presented with diffuse rash, fever, elevated transaminases, facial swelling, and hilar and mediastinal lymphadenopathy. His mediastinal lymphadenopathy was concerning for lymphoma, which led to more invasive testing to rule out malignancy. This report highlights an unusual and likely underreported presenting sign of DRESS syndrome in children.  相似文献

Drug-induced hypersensitivity syndrome (DIHS), also referred to as drug reaction with eosinophilia and systemic symptoms (DRESS), is a severe hypersensitivity drug reaction affecting the skin and multiple internal organ systems. We report a 47-year-old man with DIHS/DRESS and comorbidities (fulminant type 1 diabetes mellitus, valsartan-induced photosensitivity, vitiligo and acute interstitial nephritis). Although acute interstitial nephritis usually appears in the early phase, his is a rare case of acute interstitial nephritis more than 2 years after the onset of DIHS/DRESS.  相似文献

Drug-induced hypersensitivity syndrome (DIHS)/drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe adverse drug reaction characteristically associated with sequential reactivation of herpesviruses, such as human herpesvirus 6 (HHV-6), Epstein-Barr virus (EBV), and cytomegalovirus (CMV). Since systemic corticosteroids are thought to result in viral reactivation due to their immunosuppressive effects, we clarified the influence of systemic corticosteroid therapy on viral reactivation in DIHS/DRESS. Viral DNA in peripheral whole blood and serum sIL-2R level were measured during the disease course in twenty DIHS/DRESS patients. Six of seven patients treated without corticosteroids experienced HHV-6 viremia associated with elevated serum sIL-2R levels. In contrast, high-dose corticosteroids started within 1 week after onset tended to inhibit the occurrence of HHV-6 reactivation with remarkable suppression of serum sIL-2R level. Low-dose corticosteroids or late-start high-dose corticosteroids did not suppress occurrence of HHV-6 viremia and the increase of sIL-2R levels. HHV-6 load in the blood was clearly correlated with the serum sIL-2R level. On the other hand, increased CMV load were found in patients treated with corticosteroids regardless of the start time. The frequency of detection of EBV DNA in peripheral blood was similarly observed in all groups. In conclusion, high-dose corticosteroids started within 1 week tended to suppress HHV-6 reactivation through suppression of T cell activation. However, CMV proliferation was promoted by corticosteroids regardless of the start time. These observations suggested that careful consideration should be given to the dose and timing of administration of systemic corticosteroids in the treatment of DIHS/DRESS.  相似文献

Pustules with facial and/or neck edema is one characteristic feature of drug‐induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DIHS/DRESS) at the early stage. Although several retrospective histopathologic studies on DIHS/DRESS have been reported, the detailed histopathologic findings of facial pustules for DIHS/DRESS are unavailable. We herein report a case of DIHS/DRESS with facial pustules that was histopathologically similar to eosinophilic pustular folliculitis (EPF). Eosinophilic infiltration into expanded follicles and sebaceous glands, which is highly characteristic of EPF, was detected in pustules due to DIHS/DRESS in this case. There are numerous pathophysiological similarities between DIHS/DRESS and EPF, which may cause their histopathologic similarity. Our findings suggest that facial pustules of DIHS/DRESS may histopathologically mimic EPF.  相似文献

Drug‐induced hypersensitivity syndrome (DIHS), also referred to as drug reaction with eosinophilia and systemic symptoms (DRESS), is a multi‐organ systemic drug reaction characterized by hematological abnormalities and reactivation of human herpesvirus‐6 (HHV‐6). DIHS/DRESS is typically associated with a limited number of drugs, such as the anticonvulsants. Our group has treated 12 patients for DIHS/DRESS due to lamotrigine (LTG), but their presentation differed from that of patients with DIHS/DRESS caused by other drugs. The aim of the present study was to identify significant differences between DIHS/DRESS caused by LTG versus other drugs. We retrospectively reviewed data of 12 patients with DIHS/DRESS caused by LTG and 32 patients with DIHS/DRESS due to other drugs. The increase in alanine aminotransferase level was significantly milder in the LTG group than the DIHS/DRESS group due to other drugs. The percentage of atypical lymphocytes in the blood during DIHS/DRESS was lower in the LTG group. Serum levels of lactate dehydrogenase and thymus and activation‐regulated chemokine were also lower in the LTG group. There were fewer DIHS/DRESS patients with HHV‐6 reactivation in the LTG group than in the group treated with other drugs. Lymphocyte transformation after DIHS/DRESS onset was faster in the LTG group. The two groups did not differ with respect to the interval from first drug intake to rash, white blood cell count, blood eosinophilia or DRESS score. There were no significant histopathological differences between the two groups. The features of LTG‐associated DIHS/DRESS and DIHS/DRESS due to other drugs differ.  相似文献

Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as drug‐induced hypersensitivity syndrome (DIHS), is a rare, severe cutaneous adverse reaction characterised by fever, rash, lymphadenopathy, eosinophilia and/or other leukocyte abnormalities, and internal organ involvement and often has a relapsing–remitting course despite withdrawal of the drug. The drugs that are most implicated include aromatic anticonvulsants, allopurinol, sulphonamides, antiretrovirals (abacavir and nevirapine), and minocycline. The pathogenesis of DRESS/DIHS is far from clear but probably involves a combination of impaired pharmacokinetics and the accumulation of drug metabolites, the sequential reactivation of the herpesvirus family and genetic susceptibility conferred by the association with certain human leukocyte antigen (HLA) class I alleles. The strong association between abacavir and HLAB*5701 has enabled pharmacogenetics screening to be employed successfully to minimise the occurrence of hypersensitivity. A prolonged course of oral corticosteroids is required to treat DRESS/DIHS, given the relapsing–remitting nature of the condition with i.v. immunoglobulin and valgangciclovir reserved for refractory or life‐threatening cases.  相似文献

Background  Drug rash with eosinophilia and systemic symptoms (DRESS), a group of non-blistering severe cutaneous adverse drug reactions (SCADRs), is characterized by skin rash and multiorgan involvement. Details of this reaction have not been reported in the literature so far.
Aim  We investigate clinical and pathological features and prognosis of DRESS and hope this study will provide data concerning this disorder in Taiwan.
Methods  From January 2001 to June 2006, a total of 30 patients, diagnosed with DRESS, were enrolled and evaluated for demographic characteristics, pathological findings, complications and outcome.
Results  Patient ages ranged from 13 to 78, with an equal sex ratio. The most common offending drug was allopurinol followed by carbamazepine. Pathologic changes observed were lichenoid dermatitis, erythema multiforme, pseudolymphoma and vasculitis. Impairment of liver and renal functions and blood dyscrasia were frequent complications. Active infection or reactivation of HHV-6 was observed in 7 of 11 patients studied serologically. Two patients developed type 1 diabetes mellitus. The mortality rate was 10% (3 of 30).
Conclusions  DRESS is a heterogeneous group of life-threatening conditions. The leading drug in DRESS in Taiwan is allopurinol. High eosinophil count and multiple underlying diseases are poor prognostic factors in patients with DRESS.  相似文献

Drug reaction, eosinophilia and systemic symptoms (DRESS) is an acute and life‐threatening disease, characterised by fever, rash and systemic symptoms, including lymphadenopathy, abnormal liver function, interstitial nephritis, pulmonary and cardiac infiltrates and haematological abnormalities with eosinophilia and atypical lymphocytes. The drugs mostly associated with DRESS are anticonvulsants, allopurinol, minocycline and sulfonamides. This syndrome is rarely seen in childhood even though a large number of children have anticonvulsant treatment. An 8‐year‐old girl was admitted with fever, lymphadenopathy and skin eruptions on her trunk. Her medical history was notable for epilepsy and carbamazepine treatment had been started 5 weeks previously. Laboratory studies showed a white cell count of 6200/µL (normal, 4100–11 200/µL) with 22% eosinophils and a γ‐glutamyl transpeptidase level of 296 U/L (normal, 0–23 U/L). Laboratory tests for infections and collagen diseases were in the normal range. Persistence of fever and maculopapular eruption with generalised desquamation and the appearance of cheilitis and facial angioedema suggested a hypersensitivity reaction to carbamazepine. The carbamazepine was replaced with levetiracetam. All clinical symptoms improved within a week with corticosteroids and antihistamine treatment. Six weeks after complete recovery an epicutaneous patch test with carbamazepine was performed and a carbamazepine‐induced positive skin reaction was observed at 48‐h. Carbamazepine‐induced DRESS syndrome is a rare entity in children. An epicutaneous patch test is a useful tool for identifying the inducing agent for the DRESS syndrome and for identifying a safe anticonvulsant drug.  相似文献
