[Hemorrhagic risk factors during beta-lactam antibiotics therapy].
Any type hemorrhagic manifestation may occur 12 hours to 5 weeks after the administration of beta-lactam antibiotics. The mechanisms of blood losses proved to be by: 1) immunologic thrombocytopenia (penicillins); 2) alteration of platelet functions (semisynthetic penicillins); 3) hypoprothrombinemia (cephalosporins). The risk factors for the occurrence of hemorrhage under beta-lactam antibiotics therapy are: concomitant administration of cytostatics for a neoplastic malignancy; b) acute or chronic renal failure; c) concomitant treatment for duodenal and gastric ulcer; d) malnutrition; e) dosage and duration of antibiotic administration. The frequency of bleeding under beta-lactams is not determined as yet. A severe case diagnosed at the IIIrd Medical Clinic of Iasi presenting spontaneous daily nasal bleedings that occurred 24 hours after the initiation of the treatment with cephalosporins (Kefurox) is presented. In this patient the risk factor was chronic renal failure.
