Hantavirus disease is a recently recognised zoonosis. The main vectors are infected but healthy wild rodents or laboratory rats. Transmission to man occurs via contact with, or inhalation of aerosolised excretions. The target organs in man are the kidney (Old World) or the lung (New World), probably via a local hyperproduction of pro-inflammatory cytokines. To date, more than 33 different hantaviruses have been characterised, at least 14 of them being of clinical importance. Each serotype has its own rodent vector and its own geographical spread. In Europe, the red bank vole (Clethrionomys glareolus) is the main rodent vector, carrying the Puumala (PUU) serotype, which is the etiologic agent of a viral affection known as Nephropathia epidemica (NE). PUU infection has been recognised for the first time in Belgium in 1983. From this date on, approximately 500 cases have been diagnosed. In our regions, a diagnosis of hantavirus disease is mandatory when a febrile patient presents with lumbaches, headache, and an acute renal failure with proteinuria, and particularly with thrombocytopenia.

Babesiosis is a world-wide zoonosis caused by tick-borne hematozoan parasites of the genus Babesia. Canine Babesidae have historically been classified as "large Babesia" (Babesia canis) and "small Babesia" (Babesia gibsoni) based on the size of their intraerythrocytic forms. Genetic sequencing technology using the polymerase chain reaction (PCR) has allowed further subdivision. B. gibsoni has three strains: "Asia", "California" and a recently identified small babesial-like parasite, Theileria annae. This newly recognised piroplasm appears to be hyperendemic in northwest Spain. In order to provide some insight into the situation, all the cases diagnosed in our laboratory (NW of Spain) during 2003 were evaluated. Our study (62 samples) shows the existence of a piroplasm morphologically different from B. canis and similar to B. gibsoni, which is genetically related to T. annae. Severe regenerative anemia and thrombocytopenia are almost constant characteristics of infection with T. annae in dogs. In many cases azotemia is found. Abnormally high serum concentrations of urea and creatinin, together with elevated concentrations of inorganic phosphorus, hypoalbuminemia, hypercholesterolemia, proteinuria, high protein/creatinin and presence of hyaline and granular casts in the microscopic examination of urine sediment suggest a glomerular component to the disease. We conclude that observational research and clinical trials should be conducted in order to improve our understanding of this emerging disease in order to provide some insight into the best therapeutic practices.

Leptospirosis is a worldwide zoonosis and common in tropical and subtropical areas with high rainfall. It should be noted as an imported infectious disease although it is sporadic in Japan. Some imported cases already have been reported in Japan and these cases occurred mainly in Southeast Asia. The case discussed in this article is the first reported Japanese case infected in Vietnam. Four days after returning back to Japan after a two-week stay in the mountain area near Hue, in the middle part of Vietnam, the patient suddenly experienced chills, a high fever, sore throat, gastrocnemius pain, and headache. Conjunctival jaundice, renal function disorder, and proteinuria were observed on the third day of onset. Significant increase in antibody titers against serovar Australis and Autumnalis strains was observed in paired serum samples by microscopic agglutination test (MAT). Consequently we recognized this case as a diagnosis of severe leptospirosis (Weil's disease). Finally, renal function disorder did not deteriorate further, and then the patient recovered after the tenth day of onset with the administration of antibiotics and supportive care without sequelae. We experienced the first imported Japanese case of severe human leptospirosis infection from Vietnam that was successfully treated with ceftriaxone and minocycline.

Nephropathia epidemica, a zoonosis caused by Hantavirus infection (most commonly subtype Puumala) is associated with flu-like symptoms and acute kidney failure. Kidney manifestations are characterized predominantly by tubulointerstitial nephritis, hemorrhage into medullary tissues, interstitial edema, and tubular cell necrosis. Kidney failure is accompanied by proteinuria, and in some cases, nephrotic-range proteinuria may occur. However, the cellular mechanisms of proteinuria remain to be elucidated. We describe a Hantavirus (Puumala) infection in a 27-year-old man with acute kidney failure and severe and rapidly reversible proteinuria. Light microscopy of a kidney biopsy specimen showed only minor changes of glomeruli. However, transmission electron microscopy revealed podocyte foot-process effacement. Immunofluorescence staining of the slit diaphragm protein podocin and the tight junction protein ZO-1 revealed a partial mislocalization of these proteins. Together, these findings highlight that Hantavirus infection may perturb podocyte integrity, resulting in glomerular proteinuria. These alterations of podocytes and consequently the glomerular filtration barrier may be transient and resolve within weeks.

Although unusual in the Netherlands, acute kidney injury is sometimes caused by infection with Hantavirus, a zoonosis transmitted by rodents. Hantavirus infections can cause a syndrome known as 'haemorrhagic fever with renal syndrome', characterized by fever, acute kidney injury and thrombocytopenia. Recovery is spontaneous and treatment is mostly supportive. We describe two cases of otherwise healthy men presenting with fever and acute kidney injury. Laboratory tests revealed raised inflammatory parameters and thrombocytopenia. Urine analysis revealed proteinuria, microscopic haematuria and cell casts. Despite treatment with fluids, renal function declined and oliguria and fluid retention developed in one patient. Dialysis could be avoided, with spontaneous recovery of renal function in both cases. Serological testing revealed acute Hantavirus infection. Acute kidney injury caused by Hantavirus infections is rare in the Netherlands, but should be suspected in any patient presenting with renal failure and a history of viral infection.

Brucellosis is the most common zoonosis in the world. It can affect several organs or systems, of which the genitourinary is the second most common after the musculoskeletal. Renal involvement in brucellosis takes the form of IgA nephropathy, interstitial nephritis, pyelonephritis, mixed cryoglobulinemia and kidney failure. While the agent can be isolated in urine, renal involvement is rare (<1%). We describe a case of a 58-year-old man presenting with oedema and proteinuria. Brucellosis is considered an aetiological factor in patients presenting with glomerulonephritis in endemic regions. Brucellosis serology may assist with the early diagnosis of this rare complication.
