The Leptospirosis is an obligatory declared infectious disease, caused by a bacteria type spirochaete
Objectives: Analyse the clinical, biological and therapeutical characteristics of cases of leptospiral infection in the department of the internal medicine at CHU Ibn Sina, Rabat
Patients and Method: It was a retrospective study that begins in january 2000 still décember 2004.The inclusive criterions based on the epidemic circumstances orientated to the leptospirosis and the clinical and biological evokating arguments
Results: Seventeen cases were studied. Average age of the patients is 38 years old [28 years to 64 years] sex ratio of 7, 5 with predominance masculine. Contamination is related to of profession or exposure in a public bath in all the cases. The diagnostic period was 7-8 days. Clinically; icterus appears as a constant symptom, fever founded in 88% of the cases and hepatic cytolysis in 70% of the cases [transaminases are 2 times superior then the normal]. Renal insufficiency and thrombocytopenia are noted respectively in 58, 8% and 47% of the patients On the therapeutic plan; all patients benefited from parenteral rehydration. Thirteen patients benefited from a therapy based on Penicillin G; four patients were treated by Ampicillin parenteraly. One patient had presented with a mucocutaneous allergic reaction from Penicillin G at a 4 of the treatment so he had put on Cyclins. The average duration of hospitalization is 12, 5 days. Evolution was favourable in all patients
Conclusion: The diagnosis of leptospirosis must be evoked in all common cold [acute coryza] accompanied by hepatic cytolysis, renal insufficiency without thrombocytopenia. In the absence of serological proof, the clinical polymorphism of this disease makes the diagnosis sometimes difficult
