Clinical and serological diagnosis of Nephropathia epidemica, the mild type of haemorrhagic fever with renal syndrome.
The serological diagnosis of Nephropathia epidemica (NE), the mild European type of haemorrhagic fever with renal syndrome (HFRS), was studied by means of an indirect immunofluorescent antibody technique (IFAT) in a large outbreak in Finland (morbidity 1.4/1000 population). Acetone-fixed sections of lung of bank voles (Clethrionomys glareolus) naturally infected with Puumala virus served as antigen. Altogether 65 patients were followed serologically for up to 20 months. Serological results obtained by NE-IFAT were compared with the clinical diagnosis of NE. Of the 41 clinically accepted NE cases 40 were serologically positive. Use of the NE-IFAT serological test allowed the diagnosis to be made in seven patients for whom the clinical data were not sufficient for diagnosing NE. The antibody response in NE often appears to be slower than that against Hantaan virus. Practical recommendations are given for the clinical and serological diagnosis of the milder forms of HFRS.
