Different profiles of neurocognitive impairment in patients with hepatitis B and C virus infections.

ABSTRACT: The direct impact of chronic hepatitis B and hepatitis C on neurocognition remains elusive due to the frequent comorbidities, and the domains of the neurocognitive functions affected have rarely been investigated comprehensively. We cross-sectionally assessed the neurocognitive functions of the individuals with chronic hepatitis B, chronic hepatitis C, treated chronic hepatitis C with a sustained virologic response, and their healthy control counterparts. Laboratory examinations were used to investigate the impact of inflammation on neurocognition, exclude the medical conditions that could interfere with neurocognition assessment, and assess liver function and fibrotic severity of the liver of the participants. This study found the detrimental impact of chronic hepatitis B on language and executive functions. In contrast, individuals with chronic hepatitis C showed deficits in executive functions, psychomotor speed, memory, and attention. Successful elimination of hepatitis C resulted in improved liver function, but not neuropsychological test performance. Moreover, erythrocyte sedimentation rate level was found to mediate the deficits in the attention of individuals with chronic hepatitis C. These results demonstrate the neurocognitive deficits and the difference in the profiles of neurocognitive deficits in individuals with chronic hepatitis B and chronic hepatitis C. Our study also provided results suggesting the mediation by systemic inflammation on the attention deficit in individuals with chronic hepatitis C.

Project description:BackgroundPatients with hereditary bleeding disorders (HBDs) have always been vulnerable to transfusion-transmitted infections (TTIs) such as hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections due to being regular recipients of blood and blood products. This study aimed to detect the trends in the prevalence of HBV, HCV, and HIV infections by birthyear in Iranian patients with HBDs to show the efficacy of national interventions implemented to administrate control and to prevent these infections, i.e., blood safety, newborn HBV vaccination, and safe replacement treatments.MethodsIn this retrospective study, the trends in the prevalence of hepatitis B core antibody (HBcAb), HCV antibody (HCV-Ab), and HIV antibody (HIV-Ab) in Iranian patients with HBDs born before 2012 were assessed using patients' clinical archives. The determinants of HBV, HCV, and HIV infections were investigated in bivariable and multivariable logistic regression analyses.ResultsOut of 1475 patients with HBDs, most were male (87.7%) and diagnosed with hemophilia A (52.1%) and severe bleeding disorder (63.7%). The prevalence of HBcAb, HCV-Ab, and confirmed HIV-Ab was 22.9%, 59.8%, and 1.2%, respectively. The trends in HBcAb, HCV-Ab, and HIV-Ab were all decreasing by birthyear and reached a stable level of 0% for patients with birthyears in 1999, 2000, and 1984, respectively. In multivariable analysis, birthyear was significantly associated with HBcAb prevalence. In the multivariable analysis, type of HBD; birthyear; bleeding severity; histories of receiving packed cells, fresh frozen plasma, and cryoprecipitate before 1996; and history of receiving factor concentrate before 1997 were highly associated with the prevalence of HCV-Ab. Moreover, in the bivariable analysis, birthyear and type of HBD were associated with HIV-Ab prevalence.ConclusionThis study demonstrated the decreasing trends in HBV, HCV, and HIV seroprevalence in Iranian patients with HBDs following preventive interventions such as HBV vaccination, blood safety measures, and the provision of safe replacement treatments.

Project description:BackgroundAsymptomatic neurocognitive impairment (ANI) is the mildest form of human immunodeficiency virus (HIV)-associated neurocognitive disorders (HANDs), and functional connectivity strength (FCS) alternations have been observed in the ANI stage. However, it is not clear whether the FCS alterations are influenced by the anatomical distance. This study sought to investigate distance-specific FCS changes in HIV ANI patients.MethodsIn total, 29 patients with HAND and 32 healthy controls (HCs) were enrolled in the study. Between-group differences were detected for short, middle and long range anatomical distance FCS. A correlation analysis was performed to examine the relationship between distance-specific FCS and immunological parameters and neuropsychological tests. A receiver operating characteristic (ROC) analysis was conducted to examine the discriminative performance for HIV ANI patients.ResultsIn comparison to the HCs, the HAND patients showed increased short-range FCS in the left inferior parietal lobule (IPL), middle-range FCS in the superior temporal gyrus (STG), long-range FCS in the left precuneus (PCC), and decreased FCS in the right postcentral gyrus (PCG) (cluster P<0.05, voxel significance P<0.001). Further, the long-range FCS in the right PCG was negatively correlated with the CD4/CD8 ratio (r=-0.479, 95% confidence interval (CI): -0.735 to -0.104, P=0.015), and the distance-specific FCS also showed good classification performance between the HAND patients and HCs. The left IPL, left STG, right PCG, and left PCC had areas under the curve (AUCs) of 0.875 [95% confidence interval (CI): 0.758-0.949, P<0.0001], 0.806 (95% CI: 0.677-0.900, P<0.0001), 0.855 (95% CI: 0.734-0.935, P<0.0001), and 0.852 (95% CI: 0.754-0.950, P<0.0001), respectively. There was no significant relationship between the distance-specific FCS and the neuropsychological tests.ConclusionsDistance-specific FCS could be used to examine subtle alternations in HIV-infected patients in the ANI stage and help to explain the possible neurophysiological mechanism of HAND.
