Thyroid dysfunction and glycaemic control among Type 2 diabetes mellitus patients in Ghana: A comparative cross-sectional study

Introduction: Thyroid disorders and diabetes mellitus coexist and are prevalent endocrinopathies among adult population. Thyroid dysfunction contributes to metabolic imbalances, increase beta-cell apoptosis and glucose intolerance. There is paucity of data and contradicting findings on how thyroid dysfunction influence glycaemic control. Therefore, we evaluated thyroid dysfunction and glycaemic control among Type 2 diabetes mellitus (T2DM) patients in Ghana. Methods: A comparative cross-sectional study was conducted among 192 T2DM patients from Effia Nkwanta Regional Hospital. Three consecutive monthly fasting plasma glucose (FBG) and glycated haemoglobin (HbA1c) were analysed and the results were classified as, moderate hyperglycaemia (MH) (FBG = 6.1–12.0 mmol/L, HbA1c \u3c 7%), severe hyperglycaemia (SH) (FBG ≥ 12.1 mmol/L, HbA1c \u3e 7%) and good glycaemic controls (GC) (FBG = 4.1–6.0 mmol/L, HbA1c \u3c 7%). Thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4), body mass index (BMI) and other clinical parameters were measured. Data analysis was done using R language version 4.0.2 and p \u3c.05 was considered statistically significant. Results: There were no significant differences in age (years) between patients in the various glycaemic groups (p =.9053). The overall prevalence of thyroid disorders was 7.8% among T2DM patients. The prevalence of thyroid disorders was higher in patients with SH (11.7%) followed by those with MH (7.5%) and then those with GC (5.4%). Serum levels of TSH and FT3/FT4 ratio were significantly lower in T2DM patients with SH compared to those with MH and the GC (p \u3c.0001). However, FT4 was significantly higher in SH patients compared to the good glycaemic controls (p \u3c .01). The first tertiles of TSH [aOR = 10.51, 95% CI (4.04–17.36), p \u3c .0001] and FT3 [aOR = 2.77, 95% CI (1.11–6.92), p =.0290] were significantly and independently associated with increased odds of hyperglycaemia. Conclusion: The prevalence of thyroid dysfunction is high in T2DM and increases with hyperglycaemia. Reduced TSH and T3 may worsen glycaemic control. Periodic monitoring of thyroid function should be incorporated into management guidelines among T2DM patients in Ghana

Receptors expressions on peripheral lymphocytes and CD4+CD183+ as a diagnostics biomarker for rheumatoid arthritis: A case–control study in Ghana

Abstract Background T cell receptors play important roles in the development and progression of rheumatoid arthritis (RA). Their involvement has been reported in inflammatory autoimmune diseases. However, their role in predicting RA is still under exploration. This study evaluated the expression of CD183 (CXCR3) receptors on T‐cells and other relevant biomarkers for detecting RA and determine their relationship with disease activity. Methods This unmatched case–control study included 48 newly diagnosed RA patients and 30 apparent healthy controls from the orthopedic units of Komfo Anokye Teaching Hospital (KATH), Kumasi and Korle‐Bu Teaching Hospital (KBTH), Accra, Ghana. Sociodemographic data was obtained, and blood samples were also collected and processed for flow cytometric analysis. Statistical analyses were done using SPSS version 26.0 and R programming language. p < .05 was considered statistically significant. Results This study found a significant difference in age group (p < .0001), marital status (p = .0210), occupation (p = .0140), educational level (p = .0210) and religion (p = .0100) between RA patients and healthy controls. Moreover, hemoglobin level (p = .0010), waist circumference (p < .0001) and hip circumference (p = .0040) were significantly different between RA patients and controls. RA patients had significantly lower levels of CD4+CD183+ compared with the control group (p < .001), and was positively correlated with DAS score (r = .0397, p = .789). In Receiver Operator Characteristics analysis, CD4+CD183+ could significantly detect RA with a high area under the curve (AUC = 0.687, p = .018). At a cut‐off of 0.082, CD4+CD183+ was the best receptor biomarker for detecting RA with a sensitivity of 90.0%, specificity of 25.9%, a positive predictive value of 69.2%, and a negative predictive value of 58.3%. Conclusion CD4+CD183+ best predict RA and is positively correlated with disease activity. CD4+CD183+ could serve as diagnostics and disease‐monitoring biomarker for RA; however, it demonstrates low specificity. Future studies should be directed on CD4+CD183+ and other biomarkers to augment their diagnostics performances and routine management in RA

Factors associated with knowledge and hypoglycemia experience among patients with diabetes mellitus in Ghana: A cross‐sectional study

Abstract Background Among persons with diabetes on treatment, hypoglycemia is the most common iatrogenic acute metabolic complication. Many factors influence hypoglycemia, highlighting the need for diabetic patients to recognize, and manage these potential factors in order to reduce the rate of hypoglycemia. In this study, we assessed the knowledge, experiences of hypoglycemia, and associated risk factors among Ghanaians with diabetes mellitus (DM). Methods This cross‐sectional study included 444 clinically diagnosed DM patients from the Suntreso Government Hospital, who were on treatment for at least a year. A structured validated questionnaire was used to collect sociodemographic, lifestyle, and clinical data from the participants. Statistical analyses were performed using SPSS Version 20.0 and GraphPad Prism 8.0. Results More than half (52.7%) of the study participants had poor knowledge of hypoglycemia. Moreover, 52.9% of diabetics had experienced hypoglycemia. Participants who were in the age groups of 55–64 and 65–80 years, being retired, being diagnosed with diabetes for 11–20 years and more than 20 years, taking in alcohol, and having adequate knowledge were independent determinants of experiencing hypoglycemia. Conclusion Knowledge level of hypoglycemia among Ghanaian diabetics is low. Prompt recognition of risk factors of hypoglycemia and the careful monitoring and management of glycemic levels in high‐risk groups are important to lessen the prevalence of hypoglycemia in these populations

Frailty syndrome and associated factors among patients with hypertension: A cross‐sectional study in Kumasi, Ghana

Abstract Background and Aim Frailty is a condition marked by accumulation of biological deficits and dysfunctions that come with aging and it is correlated with high morbidity and mortality in patients with cardiovascular diseases, particularly hypertension. Hypertension continues to be a leading cause of cardiovascular diseases and premature death globally. However, there is dearth of literature in sub‐Saharan Africa on frailty syndrome among hypertensives on medication. This study evaluated frailty syndrome and its associated factors among Ghanaian hypertensives. Methods This cross‐sectional study recruited 303 patients with hypertension from the University Hospital, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. Data on sociodemographic, lifestyle and clinical factors were collected using a well‐structured questionnaire. Medication adherence was measured using Adherence in Chronic Disease Scale, and frailty was assessed by Tilburg Frailty Indicator. Statistical analyses were performed using SPSS Version 26.0 and GraphPad prism 8.0. p‐value of < 0.05 and 95% confidence interval (CI) were considered statistically significant. Results The prevalence of frailty was 59.7%. The proportion of high, medium and low medication adherence was 23.4%, 64.4% and 12.2%, respectively. Being ≥ 70years (adjusted odds ratio [aOR]: 8.33, 95% CI [3.72–18.67], p < 0.0001), unmarried (aOR: 2.59, 95% CI [1.37–4.89], p = 0.0030), having confirmed hypertension complications (aOR: 3.21, 95% CI [1.36–7.53], p = 0.0080), medium (aOR: 1.99, 95% CI [1.05–3.82], p = 0.0360) and low antihypertensive drug adherence (aOR: 27.69, 95% CI [7.05–108.69], p < 0.0001) were independent predictors of increased odds of developing frailty syndrome. Conclusion Approximately 6 out of 10 Ghanaian adult patients with hypertension experience frailty syndrome. Hypertension complications, older age, being unmarried, and low antihypertensive drug adherence increased the chances of developing frailty syndrome. These should be considered in intervention programmes to prevent frailty among patients with hypertension
