ABSTRACT
INTRODUCTION:
Few studies have pointed to the possible role of infectious diseases in triggering Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). Given the association of Hepatitis E Virus (HEV) with Guillain Barrè syndrome, we conducted a case-control study to determine the possible association of HEV infection with CIDP, analyzing possible risk factors for acquiring HEV infection in both CIDP patients and controls. MATERIALS ANDMETHODS:
82 CIDP and 260 from the general population have provided some personal information (demographics, anamnestic data and recognized risk factors for HEV infection) and underwent venipuncture blood sampling for virological assays testing for anti-HEV IgG and IgM with ELISA and RNA-HEV performing RT-PCR.RESULTS:
Anti-HEV IgG seropositivity resulted in 32 CIDP patients (39.0%) and in 45 controls (17.3%), indicating a significant association between anti-HEV IgG positivity and CIDP (OR 3.04; 95% CI 1.70-5.43, p-value <0.001), but in multivariate logistic regression the only significant associations with anti-HEV positivity were eating pork liver sausages (OR 10.443, 95% CI 2.268-60.12, p-value 0.004) and IVIg/SCIg administration (OR 31.32, 95% CI 7.914-171.7, p-value <0.001).DISCUSSION:
The higher prevalence of anti-HEV IgG in CIDP patients than in controls could be justified by chronically administering IVIg/SCIg with a passive acquisition of anti-HEV antibodies. Furthermore, all the 20 CIDP patients who underwent IVIg/SCIg administration reported HEV risk factors, so that they could have acquired the infection.CONCLUSIONS:
Further studies in a larger CIDP patient sample in treatment with therapy other than IVIg/SCIg are necessary to rule out the possible confounding effect of IVIg/SCIg.Palabras clave
