RESUMO

Background: Drug reaction with eosinophilia and systemic symptoms is an outcome of a complex interaction between specific drugs, certain herpesviruse types and the immune system of the affected individual and is characterized by an unpredictable course and recurrent flares even after withdrawal of the offending drug and administration of systemic steroids. Aims: To identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. Methods: After obtaining ethical clearance from the institutional ethics committee and a written informed consent from individual study participant, the first hundred patients who required inpatient care in Government Medical College, Kozhikode with drug reaction with eosinophilia and systemic symptoms from January 1st 2011 were included in this study aimed to identify the predictors of disease severity in drug reaction with eosinophilia and systemic symptoms. Results: Male-to-female ratio of the study group was 0.8:1. The presence of atypical cells in peripheral smear and advanced age were found to be predictors of disease severity in drug reaction with eosinophilia and systemic symptoms, whereas, sex, facial erythema and edema and absolute eosinophil count were found not to be predictors of the same. Limitations: The main limitation of this study was our inability to assess the role of human leukocyte antigen (HLA) association and herpes virus reactivation in disease severity in drug reaction with eosinophilia and systemic symptoms. This study was also not designed to evaluate the response to treatment given and the mortality caused by drug reaction with eosinophilia and systemic symptoms. Conclusions: Studies on the predictors of severity in drug reaction with eosinophilia and systemic symptoms in different population groups may enable us to identify the warning signs and help to formulate the standard therapeutic guidelines.

RESUMO

Background: The data on the histology of cutaneous lesions of drug reaction with eosinophilia and systemic symptoms (DRESS) is limited. Aims: To study the histopathology of cutaneous lesions of drug reaction with eosinophilia and systemic symptoms (DRESS) and to identify any features with diagnostic or prognostic signifi cance. Methods: All patients admitted to the dermatology ward of government medical college, Kozhikode from January 1, 2014 to December 31, 2014 with probable or defi nite DRESS as per the RegiSCAR scoring system and who were willing to undergo skin biopsy were included in this prospective study. Results: The study population comprised of nine patients. The consistent histological fi nding documented was the predominantly lymphocytic dermal infl ammatory infi ltrate. Four of the fi ve patients whose histology revealed focal interface dermatitis and keratinocyte vacuolation with or without apoptotic keratinocytes, had elevated liver transaminases. Tissue eosinophilia was associated with disease fl ares. The presence of atypical lymphocytes in peripheral smear and histological evidence of dense dermal infl ammatory infi ltrate showed an association with hepatic involvement. Limitations: The main limitations of our study were the small sample size and our inability to carry out a detailed immunohistochemistry work-up. Conclusions: In the appropriate setting, varying combinations of epidermal hyperplasia, spongiosis, parakeratosis and individually necrotic keratinocytes in the background of lymphocyte predominant dermal infi ltrate (with some atypia) favor a diagnosis of drug reaction with eosinophilia and systemic symptoms. Female sex, the presence of atypical lymphocytes in peripheral smear, dense dermal infl ammatory infi ltrate, tissue eosinophilia and interface dermatitis with or without keratinocyte necrosis was associated with a poor prognosis.
