BackgroundDiabetes mellitus (DM) represents a major health problem worldwide. Recent studies have confirmed that obesity is a state of chronic inflammation that is characterised by increased concentrations of tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and other inflammatory markers. It has been reported that increased TNF-α and IL-6 cause an immunological disturbance in DM. In the present study, the levels of fasting glucose, TNF-α and IL-6 were estimated in order to determine whether adalimumab can improve the glucose levels in obese diabetic rats.Materials and methodsTwenty-eight Wistar rats were divided into four groups: obese + diabetes + adalimumab (group 1), obese + diabetes (group 2), obese (group 3) and normal control (group 4), respectively (n = seven per group). Obesity was induced by feeding the rats in groups 1, 2 and 3 with a high-fat diet for four weeks. Some 30 mg/kg of streptozotocin (STZ) was administered to groups 1 and 2 so as to induce diabetes. Adalimumab was administered at a rate of 50 mg/kg to group 1 following the induction of diabetes. The fasting glucose, TNF-α and IL-6 concentrations were determined.ResultsA significant decrease was observed in the glucose levels of the treated rats (6.91 [0.11] mmol/L) when compared to those of the untreated rats (15.43 [0.44] mmol/L) (P < 0.001). The TNF-α levels were lower in group 1 (20.71 [0.35] ng/L) than in groups 2 (37.90 [0.27] ng/L) and 3 (25.89 [0.12] ng/L) (P < 0.001), although they were higher when compared to the levels seen in group 4 (12.44 [0.38] ng/L) (P < 0.001). The IL-6 concentrations were found to be elevated in groups 1 (22.89 [0.45] ng/L), 2 (21.00 [0.40] ng/L) and 3 (31.80 [1.32] ng/L) when compared to the levels seen in group 4 (18.70 [0.37] ng/L) (P < 0.001), although they were lower in group 1 (22.89 [0.45] ng/L) than in group 3 (31.80 [1.32] ng/L) (P < 0.001).ConclusionAdalimumab reduced the glucose and TNF-α levels of diabetic rats, which indicates that it has a therapeutic effect in terms of controlling the blood glucose.

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.

Several cross-sectional studies suggest that inflammation may be involved in the development of hypertension. The objective of the study was to examined inflammatory biomarkers-C-reactive protein (CRP), plasma fibrinogen and their correlates among hypertensive population in two tertiary hospitals in Sokoto, Nigeria. A total of 316 hypertensive patients aged 25 to 76 years and 158 age-and sex-matched apparently healthy normotensive subjects seen in the Medical and

A cross-sectional study was conducted in which patients with confirmed cases of breast cancer and age-and gender-matched apparently healthy individuals were studied.
