• The morbidity and mortality of leptospiros is have been associated with the delay between the onset of symptoms and treatment. • Our study performed in Reunion, a French island in the Indian Ocean, investigated the determinants of treatment delay. • We demonstrate that the treatment delay is longer if the patient first consults a general practitioner, and if the infection occurs during the winter period (dry season). Leptospirosis is a life-threatening zoonotic disease for which delayed treatment onset has been associated to poor prognosis. The purpose of the study was to identify the determinants of therapeutic delay in hospitalized leptospirosis cases. We carried out a retrospective multicenter study in the 4 public hospitals of Reunion Island, South Western Indian Ocean. Medical records of confirmed leptospirosis cases occurring in 2014–2015 were reviewed for socio-economic, demographic, geographic and medical data. The primary outcome measure was the therapeutic delay, defined as the time elapsed between the onset of symptoms and initiation of antibiotics. Of the 117 patients included, 107 were men, with an average age of 44.9 ± 15 years. The median therapeutic delay was 4 days (interquartile: 2–5 days) and this delay was not found to be associated with severity. The following were found to be at increased risk of having a longer therapeutic delay: cases occurring outside the epidemic period, or rainy season (OR 2.8 [1.08–7.3], P = 0.04) and cases with first medical evaluation in primary health care (OR 4.63 [1.43–14.93]; P = 0.01) instead of emergency unit. No socio-economic or geographic characteristics were found to be linked to a longer therapeutic delay. Although delayed treatment was not associated to disease severity, our results indicate that leptospirosis awareness is needed all year in the subtropical area of Reunion Island and particularly in primary care.

Abstract: Introduction. – Leptospirosis is a worldwide zoonosis caused by pathogenic species of the genus Leptospira. This infectious disease known with a high incidence in Reunion island (French overseas territories in Indian Ocean) is in state of endemia especially during rains season. Objectives. – The aim of our work was to identify the mains epidemiologic, clinical, biological, and therapeutic features of leptospirosis in children. Population and methods. – We conducted a retrospective analysis of children hospitalized in pediatric unit with the diagnosis of leptospirosis from January 2001 to June 2004 in general hospital of Saint-Denis. We found out 16 cases (mean age 14 years, range 9–17), mainly boys (ratio 7:1). Results. – The patient sera reacted most strongly with Leptospira interrogans serovars canicola (66%), icterohaemorrhagiae (17%), and sejroe (17%). Epidemiologic data indicated contact with contaminated water in most cases (68%). Jaundice was present in 43% of the patients, increased transaminase levels in 56%, renal failure in 50%, meningitis in 25%, ECG abnormalities in 6%, respiratory manifestations in 6%, systemic manifestations in 12% and thrombocytopenia in 56%. Death rate was zero, but renal failure is likely to induce life prognosis. Discussion. – The diagnosis'' traps are numerous, leading to an underestimation and underdiagnosis of the leptospirosis, more over there is a lack in specific, reliable, and quick biological test to make the diagnosis. A negative polymerase chain reaction analysis (PCR) do not exclude the diagnosis, and the microagglutination test (MAT) remains the reference of the undoubtly diagnosis of leptospirosis. It appears that it is more often the conjunction of epidemiologic data (young boy, swimming or fishing in river, rains season), with clinical and biological data that lead to the diagnosis. Diagnosis was not evoked at the emergency room in 37% of the patients. Conclusion. – Leptospirosis should be considered face to an influenza like illness especially during rains season.
