[Lemierre syndrome: several clinical features of "a forgotten disease"].

INTRODUCTION: Lemierre syndrome (LS) is considered as a forgotten disease since the beginning of Penicillin. The lack of use of beta-lactamase inhibitors antibiotics together with the increase in the use of macrolids or second-generation and third-generation cephalosporins for oropharyngeal processes has led to an increasing incidence. We propose to review all LS cases seen in an Emergency Department over the last 5 years.

METHODS: Retrospective study of patients diagnosed as LS in the Emergency Department of Hospital general universitario Gregorio Marañón from 2004 to the present. Descriptive analysis of age, gender, clinical features, laboratory and radiological results, management and outcome.

RESULTS: We had 6 patients with LS. 5 males. Median age: 25 years old. All with sore throat and pulmonary embolisms. 2 patients with negative blood cultures. 1 patient was admitted into ICU because of severe sepsis. One of the 6 developed acute renal failure, another one hemoptysis, and another a hydropneumothorax which was drained. All the patients were managed with antibiotics against anaerobes, carbapenems in 3 cases. Two patients did not receive anticoagulants, with no complications recorded. There were no deaths.

CONCLUSION: LS still has a high morbidity, therefore it must be on mind in young people with febrile pharyngeal symptoms in order to start specific treatment as soon as possible to decrease complications. Carbapenems appears to be a good therapeutic choice.
