Randomized Controlled Trial Multicenter Study
Topical tretinoin therapy and all-cause mortality.
To evaluate the relation of topical tretinoin, a commonly used retinoid cream, with all-cause mortality in the Veterans Affairs Topical Tretinoin Chemoprevention Trial (VATTC). The planned outcome of this trial was risk of keratinocyte carcinoma, and systemic administration of certain retinoid compounds has been shown to reduce risk of this cancer but has also been associated with increased mortality risk among smokers. ⋯ We observed an association of topical tretinoin therapy with death, but we do not infer a causal association that current evidence suggests is unlikely.

Factors implicated in the severity of drug reaction with eosinophilia and systemic symptoms (DRESS) have not been identified. We retrospectively describe and analyze severe cases of DRESS defined by history of intensive care unit admission and death due to DRESS. ⋯ Severe DRESS is rare. Some specificities of visceral involvement were associated with allopurinol and minocycline. However, visceral involvement comprising multiorgan failure seemed to be unpredictable. Better knowledge of DRESS is necessary to propose specific and prompt treatment. Early demonstration of human herpesvirus 6 reactivation could be considered a prognostic factor for identifying patients at higher risk and, hence, needs to be evaluated.
