BACKGROUND
Three people with clinical manifestations of acute renal failure with neurological involvement of unknown cause were admitted to a hospital in Mumbai, India. We describe clinical presentations and investigations of the cause.
METHODS
We analysed case reports and laboratory findings for the patients (age 37-43 years, two men, one woman) that were provided by the clinicians in charge. Serum and cerebrospinal fluid were tested for viral cause by IgM ELISA to Japanese encephalitis, West Nile fever, dengue, and measles. Samples were inoculated in vero-cell culture for virus isolation. The virus isolates were confirmed with indirect immunofluoresence with antimeasles immune sera and mouse monoclonal antibodies to measles HA and F proteins and with neutralisation tests using antimeasles immune sera.
RESULTS
Clinical features were fever, vomiting, oliguria or anuria, bilateral facial weakness, impaired hearing, blindness, proximal and distal areflexic limb paralysis, and respiratory paralysis. No patient had a macropapular rash. Blood urea nitrogen (4.64-27.8 mmol/L) and creatinine (601.1-1105.0 micromol/L) were high, and cerebrospinal fluid contained high concentrations of proteins and pleocytosis. Kidney biopsy samples in two patients showed severe interstitial nephritis. IgM antibodies to measles were found in blood and cerebrospinal fluid. Vero-cell cultures from serum and cerebrospinal fluid of one patient and cerebrospinal fluid of two patients, showed cytopathic effects characteristic of measles.
CONCLUSIONS
Unusual manifestations of acute renal failure with neurological involvement associated with measles virus in adults presenting without rash was confirmed. Our findings may affect the development of measles-elimination programmes.
