[Drugs cardiotoxicity]. / Complications cardiaques des médicaments.

Thanks to science advances, cancer is no longer synonymous with death. Life expectancy improvement reveals a new problem: cancer treatment toxicity, including cardiovascular complications, responsible for significant morbidity and mortality. Media scandal of drug-induced valvular heart disease did revise the risk-benefit balance of drugs used (often off-label) as anorectics. Today's society uses drugs heavily but does not accept their side effects. Knowledge and information of these complications is essential. Coronary toxicity of some treatments or drugs commonly used must be known.

High prevalence of iron deficiency in patients with acute decompensated heart failure.

AIMS: Limited data are available on iron parameters in patients hospitalized for decompensation of chronic heart failure. METHODS AND RESULTS: Iron parameters of patients hospitalized for decompensation of chronic heart failure were prospectively assessed during the 72 h after hospital admission. Iron deficiency was defined according to the 2012 European Society of Cardiology Guidelines. Overall, 411 men (75 ± 12 years; 75% NYHA functional classes III/IV) and 421 women (81 ± 11 years; 71% NYHA classes III/IV) were evaluated. The prevalence of iron deficiency was 69% in men and 75% in women (including 41% and 49% with absolute iron deficiency, respectively). The prevalence of anaemia in men (<13 g/dL) was 68% and in women (<12 g/dL) it was 52%. Among non-anaemic patients, the prevalence of iron deficiency was 57% in men and 79% in women. Only 9% of patients received iron supplementation at the time of admission (oral, 9%; intravenous, 0.2%). Multivariate analysis showed that anaemia and antiplatelet treatment in men, and diabetes and low C-reactive protein in women, were independently associated with iron deficiency. CONCLUSIONS: Iron deficiency is very common in patients admitted for acute decompensated heart failure, even among non-anaemic patients. Given the benefit of iron therapy in chronic heart failure, our results emphasize the need to assess iron status not only in chronic heart failure patients, but even more so in those admitted for worsening heart failure, regardless of gender, heart failure severity, or haemoglobin level. Initiating iron therapy in hospitalized heart failure patients needs to be investigated.

A 78-year-old woman with an acute eosinophilic gastroenteritis.

Eosinophil accumulation in the gastrointestinal tract is a common feature of numerous disorders including mainly parasitic infection, drug-induced allergic reactions, inflammatory bowel disease, and various connective tissue disorders. Digestive tissue eosinophilia requires thorough searching for secondary causes that may be specifically treated with antibiotics, dietary and drug elimination or immunosuppressive therapy. Frequency, prognosis and therapeutic implications must guide the diagnostic course. An acute eosinophilic gastroenteritis in a 78-year-old asthmatic woman receiving celecoxib is reported. She presented later with neurologic and cutaneous features and was finally treated by methylprednisolone and cyclophosphamide. The diagnostic approach leading to a Churg-Strauss syndrome (CSS) assertion is described. We discuss the pathogenesis, the management and the potential enhancing role of celecoxib in CSS gastrointestinal involvement.
