Guillain-Barré syndrome in a patient of acute Hepatitis E virus infection associated with genotype 1: Case report and literature review.

Choudhary MC, Bajpai V, Anand L, Gupta E

Hepatitis E is a serious public health problem in developing countries. Most of the patients with Hepatitis E virus (HEV) infection present with typical acute hepatitis symptoms. However, in few patients it may lead to complications such as liver failure and extrahepatic symptoms. One of the rare extrahepatic presentations of this infection is neurological complications such as Guillain-Barré syndrome (GBS) which is observed in 5.5% of HEV infected patients (mainly in developed countries). Moreover, only genotype (gt) 3 HEV was found in association with GBS among patients in developed countries whereas molecular characterisation of HEV cases detected from developing countries have not been reported till now. Here, we are reporting a case of GBS as an extrahepatic complication of HEV associated with gt1 identified by molecular characterization by performing PCR of open-reading frame 2 (ORF2) region of HEV. Phylogenetic analysis by maximum likelihood method revealed that HEV gt1 case reported in this paper rooted closely with other HEV gt1 samples from South-Asian countries with high bootstrap values indicative of fully resolved tree.
