|Abstract: ||Background: A surge in pro-inflammatory markers, Il-6 and TNF-α, has been associated with type 2 diabetes
mellitus (T2DM). However, there is no data on the dynamics of these markers in T2DM Ghanaian populations. The
aim of this study was to determine variations in the levels of IL-6 and TNF-α in T2DM patients. This study also
examined the associations of IL-6 and TNF-α with anthropometric measurement and the effect of co-morbidity
with hypertension using rural and urban dwellers in the Ashanti region, Ghana.
Methods: A nested case–control design using participants aged 25–70 years consisting of 77 T2DM ± hypertension
patients and 112 controls were selected from a larger study on Research on Obesity and Diabetes among African
Migrants (RODAM). Anthropometric measurements, blood pressure and body fat percentage were measured. Fasting
blood samples were analyzed for glucose, IL-6 and TNF-α levels.
Results: The median level of IL-6 was significantly higher (p < 0.0001) among rural dwellers compared to urban dwellers.
Inversely, urban dwellers had significantly higher (p = 0.0424) median level of TNF-α compared to rural cases. No
significant differences were observed in IL-6 (p = 0.3571) and TNF-α (p = 0.2581) among T2DM patients compared with
T2DM± hypertension patients. A weak negative correlation was found between IL-6 and BMI in urban T2DM.
Discussion: The average level of IL-6 was higher in rural T2DM participants compared with those in urban
setting. However, higher levels of TNF-α was observed among the study participants with T2DM in urban settings
compared to those of rural. In this study, we observed that co-morbidity of hypertension had no significant effect on the
levels of IL-6 and TNF-α. We are of the opinion that higher physical activity levels among rural particpants and high
obesity levels in urabn participants explain the observation but needs more numbers to validate.
Conclusion: This study revealed that IL-6 levels were higher among rural dwellers than urban while TNF-α levels were
higher in urban dwellers than rural in patients with T2DM. There was no association of body fat percentage and body
mass index with IL-6 and TNF-α levels. Co-morbidity of hypertension with T2DM had no effect on IL-6 and TNF-α levels.|
