Prognostic significance of serum telomerase activity in the monitoring of hepatitis B viral infection.

Hepatitis B viral infection could be complicated by hepatocellular degeneration, liver cirrhosis, and cancer. A total of 87 participants - 29 each of symptomatic and asymptomatic hepatitis B positive, and hepatitis B negative individuals (controls) - were recruited, and their serum samples were evaluated for serum telomerase (a biomarker for cell aging and tumorigenesis), alpha fetoprotein, and liver enzymes. Serum telomerase of the symptomatic group was higher than that of the asymptomatic group and the control (P < .001). Serum α-fetoprotein in the symptomatic group was also higher than the asymptomatic group and the controls (P < .001). The mean AST value for the symptomatic test group was higher than the asymptomatic test group and the control (P < .001). The mean ALT value for the symptomatic test group was higher than the asymptomatic test group and the control (P < .001). However, serum α-fetoprotein, AST, and ALT in the asymptomatic group were not significantly different from the controls. Serum telomerase activity was higher in symptomatic and asymptomatic HBV subjects compared with controls; this provides better information than AFP and liver enzymes that were only higher in symptomatic subjects. Serum telomerase activity could therefore be used as a marker in predicting the onset of hepatocarcinogenesis.Abbreviation listHBV: Hepatitis B virus; AFP: Alpha fetoprotein; ALT: Alanine transaminase; AST: Aspartate transaminase; HCC: Hepatocellular carcinoma; ELISA: Enzyme-linked immunosorbent assay; CLD: Chronic liver disease; CMV: Cytomegalovirus; TERT: Telomerase reverse transcriptase; TERC: Telomerase RNA component; WHO: World Health Organization; BUHREC: Babcock University Health Research Ethics Committee; CTL: Cytotoxic T-lymphocyte.

Serological evidence of HIV, Hepatitis B, C, and E viruses among liver disease patients attending tertiary hospitals in Osun State, Nigeria.

Hepatitis infection in HIV positive individuals with liver diseases causes high mortality worldwide. HIV worsens the pathological effect of hepatitis viruses and potentiates reactivation of latent hepatitis infections due to reduced immunity. This research therefore aimed to study the occurrence of HIV and hepatitis viruses among liver diseases patients (LVDP) attending tertiary hospitals in Osun State, southwestern Nigeria. A total of 121 LVDP blood samples collected were tested for HIV and Hepatitis B, C, and E using and enzyme linked Immunossorbent assay (ELISA). Data were analyzed using packages within SPSS and P ≤ 0.05 was considered significant. Prevalence of 32.2%, 0.8%, 10.7%, and 18.2% for HBsAg, Anti-HCV, HEV-IgM, and HIV were found respectively. Marital status showed a significant association with HEV-IgM infection (χ2 = 9.869, P = .020). The prevalence of HBsAg, HEV, and HIV among LVDP in Osun State is alarming and health education among the patients and general populace is hereby advocated. High HEV-IgM seroprevalence implies that HEV routine screening should be incorporated into blood screening. Since HEV is associated with unhygienic practice, people should be enlightened on how to improve their living conditions.

High seroprevalence of viral hepatitis among animal handlers in Abeokuta, Ogun State, Nigeria.

Viral hepatitis is a deadly disease which can manifest as acute, chronic, hepatocellular carcinoma, and liver failure. Information about hepatitis is scarce among animal handlers. Due to Federal Government of Nigeria diversification programmes, many people are now involved in animal farming which can make them susceptible to viral hepatitis. This study aimed at determining the prevalence of Hepatitis B, C, and E viruses among animal handlers in Abeokuta, southwestern Nigerian. A total of 156 subjects were recruited for the study. Sociodemographic and risks factors data were fetched from subjects using interviewer-administered questionnaire. Blood samples were collected via venepuncture and tested for HCV, HBV, and HEV using ELISA technique. Results were analyzed using SPSS software version 21.0 and P value ≤ 0.05 was considered significant. The prevalence of HCV, HBV, and HEV were 46 (29.5%), 20 (12.8%), and 4 (2.6%) respectively while 6 (3.8%), 1 (0.6%), and 1 (0.6%) had co-infection of HBV-HCV, HBV-HEV, and HCV- HEV respectively. This study concludes that there is high prevalence of hepatitis C and B viruses among animal handlers in Abeokuta, Ogun state which is of significant public health problem, warranting further attention and research.

High Viral Hepatitis Infection among Pregnant Women Attending Antenatal Clinic in Adeoyo Maternity Teaching Hospital Ibadan (AMTHI) Oyo State, Nigeria.

Hepatitis B virus (HBV), Hepatitis C virus (HCV), and Hepatitis E Virus (HEV) are highly endemic in several African countries including Nigeria with adverse effects on pregnancy outcomes resulting in fatality. This study aimed to determine the viral hepatitis in pregnant women attending antenatal clinic, AMTHI. Informed consent questionnaire was administered before blood collection via venipuncture. a total of 904 pregnant women plasma samples were tested for HBV, HCV, and HEV using ELISA kit. Data was analyzed using packages within SPSS software and P ≤ 0.05 was considered significant. Out of 904 samples analyzed, the overall prevalence of hepatitis infections among pregnant women attending antenatal clinic in AMTHI was 66(7.3%). High prevalence of the hepatitis infections was found among young women within the age group 21-30 which might be associated with active sex, intravenous drug use, sharing of sharp objects and alcoholism. Blood group O Positive had the highest prevalence of hepatitis. There was statistical significance between blood group and HBsAg infection (P < .05). Genotype AA women had highest prevalence of hepatitis. This study showed significant association between HBsAg, HCV, and HEV positive status with blood group O positive and Genotype AA pregnant women.

Prevalence of Cryptosporidium infection and related risk factors in children in Awo and Iragberi, Nigeria.

Cryptosporidiosis is an important major cause of enteric parasitic infection among infants and children in developing countries with morbidity and mortality especially among immune- deficient individuals. Poor performance of traditional diagnostic procedures in many laboratories can resulted in misdiagnosis and mistreatment, thereby probably promotes drug resistance. This study was carried out to determine the prevalence of enteric Cryptosporidiosis in children attending primary health centers in Egbedore local government area of Osun State, Nigeria between July-December 2014. Informed consent questionnaires were administered to collect demographic data and a total of 180 stool samples were collected to detect Cryptosporidium oocyst and antigen using Modified Ziehl Neelsen (MZN) and enzyme-linked immunosorbent assay (ELISA) methods, respectively. Prevalence of 38.3% (72/188) and 46.8% (88/188) was obtained by MZN and ELISA, respectively. The prevalence was higher in children between 1-2.5 years and lower in children above 2.5 years. There was significant association between diarrhea and prevalence rate (P = 0.006; P < 0.05) for ELISA and ZN, respectively. The present results show that cryptosporidiosis poses a public health challenge in children found in Egbedore. This study also warrants intensified effort towards awareness of the disease and proper diagnosis is needed most especially among immunocompromised individuals.
