Testosterone Correlation with Low and High Density Lipoprotein in Male Type 2 Diabetics

Aim: To determine correlation of serum testosterone with low and high density lipoprotein in male type 2 Diabetics presenting at a tertiary care hospital of Sindh.

Methodology: A cross sectional study, Department of Biochemistry and Department of Medicine, Liaquat University Hospital from January 2018 to February 2019. One hundred male type 2 diabetics (cases) and one hundred age matched male (control) were selected through non – probability purposive sampling. Male diagnosed cases of DM belonging to 4th to 6th decade of life was included. Blood samples were collected by venesection and sera were squeezed by centrifugation and stored at – 20 0C in refrigerators. Testosterone was estimated by the ELISA (competitive immuno- assay) assay method and blood lipids - cholesterol, triglycerides (TAGs), LDLc and HDLc by colorimetric method. Pearson`s correlation was generated on Statistical software SPSS 21.0 version (IBM, Incorp, USA) for correlation of serum testosterone with lipids fractions (P≤0.05).

Results: Age shows majority of male type 2 diabetics were in their 5th decade. We found low serum testosterone level (10.85±4.7 mmol/L) in cases compared to normal testosterone level (13.39±3.8 mmol/L) in control (P=0.0001). Pearson`s correlation shows inverse association with HDLc (r= -0.70) (P=0.0001) and positive association with LDLc (r= 0.670) (P=0.0001).

Conclusion: We found low serum testosterone in male type 2 diabetics that showed negative correlation with high density lipoprotein (HDLc) and positive correlation with low density lipoprotein (LDLc).
