Prevalence of some hepatitis B virus markers among pregnant women attending antenatal clinic in Specialist Hospital Sokoto Nigeria.

BACKGROUND: Hepatitis B virus infection is a global public health problem. The virus has infected more than one-third of the global population. It has been estimated that 360 million chronic carriers are living around the world with a high risk for developing cirrhosis, hepatic carcinoma and hepatic failure. OBJECTIVE: The aim of this study was to determine the prevalence of some hepatitis B markers among pregnant women attending antenatal clinic in Sokoto Specialist Hospital, Nigeria. METHODS: The hepatitis testing was carried out using the Skytec-Rapid Diagnostic HBV-5 rapid kit (Skytec-Rapid Diagnostic, USA). The kit is based on lateral flow chromatographic immunoassay for the qualitative detection of HBsAg, HBsAb, HBeAg, HBeAb, and HBcAb in human serum or plasma. Panel format can conveniently test for five targets at once and utilizes all markers to help distinguish between acute and chronic infections. RESULTS: Out of 117 pregnant women tested, 15 were positive for HBsAg (12.8%), 6 positive for HBsAb (5.1%), 1 for HBeAg (0.9%), 14 tested positive for HBeAb (12.0%), and 14 tested for HBcAb (12.0%). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on ethnicity. HBsAb was significantly higher among the Hausa ethnic group (p= 0.001). The prevalence of HBsAb, HBeAg, HBcAb and HBcAb was not affected by ethnicity (p> 0.05). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on age. Infection by the hepatitis B virus markers was higher among young adult and middle age groups. The difference was however not statistically significant (p> 0.05). The prevalence of HBsAg, HBsAb, HBeAg, HBcAb and HBcAb was compared based on the educational status, previous history of blood transfusion, jaundice, employment status and previous history of still births among the pregnant subjects. There were no statistically significant differences in the prevalence of Hepatitis B virus markers (p> 0.05). CONCLUSION: The study observed a high prevalence of various hepatitis B viral markers among pregnant women attending antenatal care in Specialist Hospital Sokoto. There is need for routine screening of all pregnant women and infants born to hepatitis B positive mothers. Government and non-governmental organizations should intensify efforts to enlighten the general population on the public health importance of the disease and the importance of hepatitis screening. There is also need for the development of a treatment protocol for the management of pregnant women positive for hepatitis B to prevent mother to child transmission. There is an urgent need for the implementation of evidenced-based best practice of providing universal vaccination against hepatitis B for all hepatitis B negative women of child bearing age in particular and all Nigerians in general.

Some haematological parameters, manganese and zinc levels among diabetic patients of African descent attending Specialist Hospital Sokoto, Nigeria.

BACKGROUND: World Health Organization statistics identifies that there are about 150 million people with diabetes mellitus worldwide and suggest that this figure may double by 2025. OBJECTIVE: This research was conducted to determine the status of full blood count, zinc and manganese levels among Diabetic patients attending Specialist Hospital, Sokoto. METHODS: The participants were divided into two groups; 58 diabetic subjects and 29 non-diabetic controls. Five milliliters of blood were collected into EDTA and plain containers for full blood count, serum zinc and manganese analysis. The FBC investigation was carried out using automated Mythic Haematology analyzer (Orphee, Switzerland) while Zn and Mn investigations were carried out using Atomic Absorption Spectrometry (AAS). The FBC, Zn and Mn status of both control and subjects were compared statistically. RESULTS: The results obtained in this study showed a significant increase in RBC, PCV, Hb, Basophils, Eosinophil, Lymphocyte count and Manganese levels of diabetic subjects (p⩽ 0.05) when compared with controls. There was no statistically significant difference in the other FBC parameters and Zinc levels between diabetic subjects and non-diabetic controls (p> 0.05). There was a statistically significant difference in the Hb, PCV and lymphocyte of diabetic patients based on gender (p< 0.05). FBC, Manganese and Zinc have no effect based on age group, while other socio-demographic factors also have no effect on the FBC, Manganese and Zinc parameters of diabetic patients. The study also showed no statistical difference in the FBC, Manganese and Zinc of smokers and non-smokers (p> 0.05, respectively). In conclusion, this research shows that some haematological parameters (RBC count, Basophils, Eosinophil, Lymphocyte, Hb and Manganese) of the diabetic patients are significantly higher compared to non-diabetic controls. Marital status had a significant effect on the Hb, PCV and Lymphocyte of the diabetic patients (p< 0.05). The age group had no significant effect on the Hb, PCV and Lymphocyte of diabetic subjects (p> 0.05).CONCLUSIONS There is need to routinely monitor the full blood count, zinc and manganese levels among diabetic subjects in the area to optimize the care offered to these patients.

Comparative evaluation of haematological parameters and erythrocyte membrane stability in pregnant and lactating goats in different seasons of tropical Savannah.

Haematological parameters and erythrocyte osmotic fragility (EOF) are commonly used as indicators of health status and erythrocyte membrane integrity. Variations in haematological parameters and EOF in late gestation and early lactation during the cold-dry (CDS), hot-dry (HDS) and rainy (RAS) seasons were studied in sixty (n = 60) Red Sokoto goats (20 goats for each season). The ambient temperatures and temperature-humidity index recorded were higher in the afternoon hours of the HDS and RAS, but lower in the morning hours of the CDS as compared with the thermoneutral zone of goats. Results revealed that the pregnant goats had significantly (P < 0.05) lower PCV and RBC, but higher haemoglobin parameters (Hb, MCH and MCHC) in RAS. Unlike in the pregnant goats, higher (P < 0.05) values of PCV and RBC were observed during the HDS as compared with the CDS and RAS in lactating goats. The EOF was significantly higher during lactation than pregnancy in the CDS and HDS. Similarly, the magnitude of the left shift in fragiligram during the CDS was more marked in pregnant compared with lactating goats. During gestation, the CDS had lower (P < 0.05) EOF than HDS and RAS, with a marked left shift in the fragiligram of both pregnant and lactating goats during the CDS. In conclusion, seasonal variations exist in physiology of erythrocytes of goats during the peri-partum period, with an increase in PCV and RBC, but a decrease in haemoglobin parameters in pregnant compared with lactating goats during the RAS. Erythrocyte stability and membrane integrity were higher in pregnant than lactating goats, and also higher during the CDS than the HDS and RAS, irrespective of reproductive status. This information may be useful in the design of animal breeding and is of value in animal welfare, research, diagnosis and management of haematological conditions during the peri-partum period.

Prevalence of Hepatitis B surface antigen among biomedical students of African descent in Usmanu Danfodiyo University, Sokoto, Nigeria.

BACKGROUND: Hepatitis B (HB) is a serious global public health problem that put health professionals particularly at risk. OBJECTIVE: The aim of this study was to investigate the prevalence of Hepatitis B surface antigen (HBsAg) among Biomedical Students of African descent attending Usmanu Danfodiyo University Sokoto in North-Western Nigeria. METHODS: The Onsite HBsAg (CTK Biotech, USA) was used to detect the presence of hepatitis B surface antigen. RESULTS: We tested 186 consecutively-recruited students consisting of 147 males and 39 females aged 18-35 years (mean age 26 ± 2.0 years). Of the 186 students tested, 25 (13.4%) were positive for HBsAg. The prevalence of HBsAg was significantly higher among students in the 21-25 years age group. Hepatitis B vaccination uptake among students was 7%. Majority of subjects were single 173(93.1%) compared to married 13 (6.9%). Ethnic distribution of the subjects indicated that 104(55.9%) were Hausa compared to Yoruba 32 (17.2%), other ethnic groups 21(11.3%), Fulani 20(10.8%) and Igbo 9(4.8%). CONCLUSIONS: This study indicates a high prevalence of hepatitis B virus infection among Biomedical students in Sokoto, North Western, Nigeria. Finding from this study is enough justification for the implementation of a policy to routinely test students entering into the biomedical professions for Hepatitis B virus infection. There is the need to provide hepatitis B vaccination universally to all those who are found negative prior to commencement of their biomedical training. There is also need to educate students entering biomedical professions and healthcare workers on the modes of transmission and prevention, importance of being compliant with protective vaccination as well as the need to observe universal precaution and infection control guidelines during their training and future professional practice.
