Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hantavirus disease are zoonotic infections and remain a clinical challenge with globally increasing incidence and multiple serious outbreak situations in Europe within the last years. Hantavirus disease encompasses two clinical syndromes, hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) caused by Old World and New World hantaviruses, respectively. Depending on the causative Old World hantavirus species, clinical course of HFRS can vary from mild to moderate to severe.

At present, there is no specific therapy available for hantavirus disease. As the clinical course of hantavirus disease is dependent on the causing viral pathogen and as there worrisome hints that clinical course HFRS and HCPS overlap, further studies with regard to the disease course are mandatory. Furthermore, the examination of attributable mortality and costs of hantavirus disease will need to be studied on a multinational basis and therefore HantaReg will particularly use a matched case control design.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Hantavirus disease are zoonotic infections and remain a clinical challenge with globally increasing incidence and multiple serious outbreak situations in Europe within the last years. Hantavirus disease encompasses two clinical syndromes, hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS) caused by Old World and New World hantaviruses, respectively. Depending on the causative Old World hantavirus species, clinical course of HFRS can vary from mild to moderate to severe. HRFS caused by Hantaan virus, Amur virus and Dobrava-Belgrade virus lead to severe clinical course of the disease, with mortality ranging from 10-15%, whereas Seoul virus and Puumula virus result in mild to moderate from of disease with a mortality below \<1%, also referred to as nephropathia epidemica. New World hantaviruses cause HCPS leading to acute respiratory distress syndrome (ARDS) and heart rhythm disorders with attributable mortality ranging high from 30-50%. However, there are hints that HRFS and HCPS overlap with a combined clinical course with cardiopulmonary, renal and hemorrhagic symptoms being present simultaneously. Due to climate changes and globalization, outbreak situations of hantavirus disease throughout Europe are increasing and there are worrisome trends regarding changing of species distributions in Europe.

At present, there is no specific therapy available for hantavirus disease. Treatment approaches are primarily supportive with admission of patients to the intensive care unit (ICU) and maintenance of fluid and electrolyte balance. Patients with severe renal insufficiency and fluid retention, pulmonary edema or hyperkalemia may require dialysis. In case of extensive thrombocytopenia and present bleeding, platelet transfusion may be needed. In HCPS, treatment approaches consist of the supplementation of oxygen, mechanical ventilation and in case of extended acute respiratory distress syndrome (ARDS) extracorporeal membrane oxygenation (ECMO).

Due to increasingly frequent outbreak situations and globally chances in species distributions, a worldwide surveillance in epidemiology and species attribution is needed. As the clinical course of hantavirus disease is dependent on the causing viral pathogen and as there worrisome hints that clinical course HFRS and HCPS overlap, further studies with regard to the disease course are mandatory. Furthermore, the examination of attributable mortality and costs of hantavirus disease will need to be studied on a multinational basis and therefore HantaReg will particularly use a matched case control design.

The objective of the Hantavirus Registry - HantaReg is to overcome the lack of knowledge on epidemiology, clinical course and prognostic factors for hantavirus infections and their complications, as well as to serve as a platform for future studies and outbreak situations.
