The Drug rash with hypereosinophilia and systemic symptoms (DRESS) syndrome, or hypersensitivity syndrome, is a severe drug-induced hypersensitivity syndrome. It has been exceptionally described with ciprofloxacin. We report a 47-year-old-woman who developed DRESS syndrome, 2 days after taking ciprofloxacin for a urinary infection. She had a generalized maculopapular rash, severe rhabdomyolysis, liver involvement, renal failure and hypereosinophilia. Clinical symptoms had completely resolved after ciprofloxacin withdrawal. Renal failure has decrease after short corticosteroid treatment., (Copyright © 2015 Association Société de néphrologie. Published by Elsevier SAS. All rights reserved.)

Many drugs may induce psoriatic lesions or exacerbate preexisting psoriasis. We report an exceptional case of psoriasis vulgaris probably induced by clarithromycin. A 37-year-old man was prescribed for pharyngitis clarithromycin 500mg twice a day. On the third day of treatment, he presented a non pruriginous erythemato-squamous eruption, of trunk and limbs. Skin biopsy showed a typical aspect of psoriasis vulgaris. The drug was interrupted and the patient was treated by topical corticoids with rapid improvement.

Frequency of colitis induced by drugs is often under estimated. Antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDS) are usually incriminated. In this study, we classified colitis according to the main responsible drug with a focus on clinical symptomatology, physiopathology, evolution, and complications. We describe colitis due to antibiotics, NSAIDS, laxatives, vasoconstrictive agents, oestroprogestatives, chemotherapy and drugs induced microscopic colitis. The last one represents a particular case; it can be idiopathic, infectious or drugs induced. Its physiopathology is not well known and its diagnosis is based only on histologic criterion. Drug responsibility is easy to determine only for pseudomembranous colitis. In the other cases, chronology is very variable and the clinical, endoscopic and histological elements are rarely specific. Because of the large number of drugs that may induce colitis, it is necessary to search for potentially responsible drugs, especially if there is no obvious cause of the colitis., (© 2010 Société Française de Pharmacologie et de Thérapeutique.)
