This study evaluated the levels of anti-insulin antibodies (AIAs) and the influence of some antidiabetic medications on AIA in diabetes mellitus (DM) patients with retinopathy. An observational cross-sectional study. A lower titer of AIA IgG was observed in the diabetic retinopathy (DR) and DM-only study categories compared with the control group [DR = 86 (5-560), DM-only = 50 (5-500), versus control = 200 (7-565); p = 0.

Background And Aims: Cardiovascular diseases (CVDs) are among the leading causes of disability and early death in sub-Saharan Africa. Most of the current blood tests for CVD diagnosis involve performing about three test profiles; often at additional cost to patients. C-peptide, a cleavage product of proinsulin, is a promising marker that has the potential to serve as a proxy marker for diagnosing CVDs in resource-poor settings.

The absence of albumin prompts the liver to produce more proteins to make up the difference. The therapeutic significance of these additional proteins in NS is not yet fully understood.

Accumulation of lipids in the body may be due to an imbalance in the metabolism of lipids, glucose and proteins. Ceramides are a sphingolipid class of lipids that are biologically active and vital in the production of more complex lipids.

Alterations in leptin concentrations are associated with CKD-related cardiovascular problems such as hypertensive heart disease (HHD). Despite the link, data on the precise function of leptin in people with CKD and HHD is scant.

Polymorphism variants of SLC10A1 play roles in HBV infection, viral clearance, treatment outcome, and complications, in diverse ethnic groups and countries. However, no such study has been conducted in the Ghanaian population, a country with HBV endemicity.

Methods: A cross-sectional, observational study.
Objective: This study aimed to evaluate dyslipidemia in Ghanaian subjects with type 2 diabetes.
Results: Hundred individuals with type 2 diabetes and 61 apparently healthy controls participated. The prevalence of hypercholesterolemia among persons with type 2 diabetes was 53%.

Objective: Highly active antiretroviral therapy (HAART) has considerably reduced HIV/AIDS-related morbidity and mortality; however, the therapy has been associated with the development of cardiovascular disease (CVD), and genetic predisposition factors may aggravate disease outcome. This study was aimed at investigating the relationship between haptoglobin phenotypes and risk factors of CVD in HIV patients.
Methods: A total of 105 HIV sero-positive patients on HAART and 75 HIV-infected HAART-naïve individuals were enrolled in the study.
Objective: This study aimed to evaluate the effect of different levels of exercise on markers of oxidative stress and selected metabolic parameters in Ghanaian young adults.
Results: Significant increases in a marker of oxidative stress malondialdehyde and antioxidants such as superoxide dismutase and uric acid were observed in the exercisers compared with the inactive group (p < 0.05).
Objectives: Elevated immunoglobulin levels have been strongly linked to the development and progression of inflammatory disorders such as type 2 diabetes and obesity. This study aimed to evaluate circulating immunoglobulin levels and to identify other metabolic factors that influence humoral immune response among Ghanaian subjects with type 2 diabetes.
Methods: A comparative cross-sectional study conducted at the National Diabetes Management and Research Center, Accra.
Background: Oxidative stress and antioxidants have been implicated in many diseases including prostate cancer and benign prostatic hyperplasia (BPH). Lipid peroxidation contributes to oxidative stress. However, new and emerging antioxidants such as paraoxonase 1 (PON1) and arylesterase (ARE) associated with lipoprotein peroxidation have not been examined in BPH patients.

Results: Obese subjects with type 2 diabetes had lower leptin but higher hsCRP levels compared with obese non-diabetic controls. There were negative correlations within the control group for glucose vs % muscle mass (r = - 0.
Background: Leptin levels start increasing from the early stages of pregnancy, irrespective of the maternal body mass index. Leptin levels are increased in pregnant women with preeclampsia (PE) and may precede the clinical onset of the disease, with peaks occurring around 28 weeks of gestation. This study was aimed at determining whether serum leptin concentration and body fat percentage are significantly altered during the first trimester in pregnancies that subsequently develop PE and whether such changes are useful in predicting the disease.

Renal tubular lysosomal enzyme activities like alanine aminopeptidase (AAP) and N-acetyl-β-D-glucosaminidase (NAG) have been shown to increase in patients developing diabetic nephropathy and nephrosclerosis. This study aimed to determine the activities of N-acetyl-β-D-glucosaminidase and alanine aminopeptidase and albumin concentration in urine samples of patients with type 2 diabetes. One hundred and thirty (65 type 2 diabetic and 65 nondiabetic) subjects participated in this study.

Design: A cross-sectional study involving secondary analysis of shift and non-shift work from an industry in Ghana.
Testosterone plays a vital role in obesity, glucose homeostasis, and lipid metabolism. The aim of this study was to investigate androgen levels and its association with obesity in Ghanaian men with type 2 diabetes. The study showed that serum total and free testosterone concentrations were lower in male patients with type 2 diabetes and that obesity was strongly associated with low levels of total and free testosterone in Ghanaian men with type 2 diabetes.
View Article and Find Full Text PDFLeaves of the Gymnema sylvestre (GS) plant have been used to treat diabetes mellitus for millennia, but the previously documented insulin secretagogue effects of GS extracts in vitro may be non-physiological through damage to the beta-cells. We have now examined the effects of a novel GS extract (termed OSA) on insulin secretion from the MIN6 beta-cell line and isolated human islets of Langerhans. Insulin secretion from MIN6 cells was stimulated by OSA in a concentration-dependent manner, with low concentrations (0.

As mitochondrial oxidative phosphorylation plays a key role in glucose-stimulated insulin secretion (GSIS), oxygen-sensing pathways may modulate insulin release. The von Hippel-Lindau (VHL) protein controls the degradation of hypoxia-inducible factor (HIF) to coordinate cellular and organismal responses to altered oxygenation.
