Lamotrigine hypersensitivity syndrome and spiking Fever

Management of Psychotropic Drug-Induced DRESS Syndrome: A Systematic Review

Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous eruption that has been linked to several common drugs and drug categories, including antiepileptics, allopurinol, sulfonamides, and various antibiotics; however, because of a number of recent case reports linking psychotropic medications to this condition, DRESS is increasingly recognized among psychiatrists. We systematically reviewed all psychotropic drugs linked to DRESS syndrome, and this article summarizes the clinical management relevant to psychiatric professionals. A comprehensive search was performed using Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Database of Systematic Reviews, Web of Science, Scopus, and Litt's Drug Eruption and Reaction Database for articles published in English during the past 20 years (1996-2015) using the search terms (1) psychotropic drugs OR serotonin uptake inhibitors AND DRESS or (2) psychotropic drugs AND drug reaction (or rash) eosinophilia systemic syndrome, and all article abstracts were screened for inclusion and exclusion criteria by 3 reviewers. Two independent reviewers examined the full text of 163 articles, of which 96 (25 original articles, 12 review articles, 55 case reports, and 4 letters to the editor) were included in the systematic review. We identified 1072 cases of psychotropic drug-induced DRESS, with carbamazepine, lamotrigine, phenytoin, valproate, and phenobarbital being the most implicated drugs. Based on our review of the literature, we outline management principles that include prompt withdrawal of the causative drug, hospitalization, corticosteroid therapy, and novel treatments, including intravenous immunoglobulin, cyclophosphamide, and cyclosporine, for corticosteroid-resistant DRESS. Finally, we outline strategies for treating comorbid psychiatric illness after a DRESS reaction to the psychotropic medication.

Lamotrigine induced DIHS/DRESS: Manifestations, treatment, and outcome in 57 patients

OBJECTIVE

To evaluate the clinical features, course, response to treatment, and outcome of lamotrigine induced drug-induced hypersensitivity syndrome (DIHS) or drug reaction with eosinophilia and systemic symptoms (DRESS).

METHODS

A comprehensive PubMed and Scopus search (covering the period from January 1999 through April 2014) of the English and non-English literature (with English abstract) was conducted to identify published reports of severe cutaneous adverse reactions (SCARs) associated with lamotrigine therapy.

RESULTS

This study population included 57 patients, of whom 38 (66.67%) were female and 19 (33.33%) were male. The latency period varied from 9 days to 120 days, with a mean of 27.58 ± 20.65 days. Multisystem involvement was present in 97.37% (37/38) patients. Systemic corticosteroids were administered to (61.29%) 19/31 patients. 35/38 (92.11%) patients recovered completely, one patient developed liver failure and needed liver transplant, one died from septic shock and one died from multiple organ failure.

CONCLUSIONS

We found a greater predominance of women with LTG-DIHS/DRESS, and 68.42% patients were >18 years of age. The presenting symptoms in most of patients were fever, skin rash, liver involvement, hypereosinophilia, and lymphadenopathy. Lamotrigine is associated to a rather high risk of severe cutaneous adverse reactions and to the risk of dying from such reactions, likes many other anticonvulsants. Early recognition and withdrawal of the suspected agent may avoid irreversible damage to the organs will be life saving.
