Clinical Trial Summary

Leptospirosis is a worldwide zoonotic diseases caused by pathogenic Leptospira spp. Human are accidental hosts, who acquired infections after exposition to animal urine, contaminated water or soil, infected tissue. Incidence of invasive leptospirosis disease causing acute kidney injury, acute respiratory distress syndrome (ARDS), myocarditis, hepatic dysfunction, hemorrhage and multi-organ failure, is globally increasing and there have been frequent outbreak situation throughout the world. Due to increasing outbreak situations and globally chances in species distributions, a worldwide surveillance in epidemiology and species distribution is urgently needed. The objective of the Leptospirosis Registry - LeptoScope is to overcome the lack knowledge on epidemiology, clinical course, prognostic factors and molecular characteristics for invasive leptospirosis disease.

Description:

Leptospirosis is a worldwide zoonotic diseases caused by pathogenic Leptospira spp. Human are accidental hosts, who acquired infections after exposition to animal urine, contaminated water or soil, infected tissue. During bacteremia, Leptospira spp. may lead to invasive, deep-seated leptospirosis with infection of kidney, liver, heart and the central nervous system. Although cleaned from blood and most tissue by immune response, Leptospira spp. can persists and multiply in the tubuli of kidneys. Incidence of invasive leptospirosis disease causing acute kidney injury, acute respiratory distress syndrome (ARDS), myocarditis, hepatic dysfunction, hemorrhage and multi-organ failure, is globally increasing and there have been frequent outbreak situation throughout the world. In Europe, invasive leptospirosis disease is less common than in the tropical and subtropical countries, however due to climate change incidence is rising, and there are worry-some trends concerning chancing species distribution and multiple outbreak situations throughout central Europe. Current treatment approaches consist of antibiotic therapies. Additionally, salvage supportive treatment approaches of critical ill patients are common in invasive leptospirosis disease requiring dialysis, hemodynamic support, mechanical ventilation or even extracorporeal membrane oxygenation (ECMO). Furthermore, invasive leptospirosis disease is associated with the development of chronic kidney disease. Due to increasing outbreak situations and globally chances in species distributions, a worldwide surveillance in epidemiology and species distribution is urgently needed. Additionally, the examination of attributable mortality and costs analysis of invasive leptospirosis disease will need to be studied on a multinational basis and therefore LeptoScope will particularly use a matched case control design. The objective of the Leptospirosis Registry - LeptoScope is to overcome the lack knowledge on epidemiology, clinical course, prognostic factors and molecular characteristics for invasive leptospirosis disease. Additionally, LeptoScope serves as a platform for monitoring complications of invasive leptospirosis disease and outbreak situations.
