Epstein-Barr virus reactivation induced myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA)-associated vasculitis.

We present a patient with systemic symptoms including 4 months of dyspnoea worsened with exertion, fatigue, rhinorrhoea, intermittent facial swelling, generalised lymphadenopathy and weight loss. Laboratory studies demonstrated proteinuria and eosinophilia. His serology was consistent with Epstein-Barr Virus (EBV) reactivation.

Persistent neuropsychological impairment associated with West Nile virus infection.

West Nile virus infection can result in prolonged subjective complaints of cognitive and functional decline even in the absence of a neuroinvasive form of infection. Persistent cognitive and functional complaints could be a result of general somatic symptoms, emotional distress, or residual central nervous system damage or dysfunction. Most studies of cognition in postacute West Nile virus infection rely on self-report.

Myocarditis in West Nile Virus infection.

West Nile virus (WNV) myocarditis has been documented pathologically in birds and mammals but has rarely been reported in human clinical syndromes. We describe myocarditis associated with WNV.

Mental status after West Nile virus infection.

Mental status after acute West Nile virus infection has not been examined objectively. We compared Telephone Interview for Cognitive Status scores of 116 patients with West Nile fever or West Nile neuroinvasive disease. Mental status was poorer and cognitive complaints more frequent with West Nile neuroinvasive disease (p = 0.
