RESUMO

Type 2 diabetes is considered as a major health burden due to its rising prevalence and disabling, life threatening complications. Dyslipidemia, often coexisting with T2DM as a feature of insulin resistance, is hypothesized to be linked with altered magnesium homeostasis. This study was designed to evaluate the serum magnesium levels and its influence on serum lipids in type 2 diabetics. Lipid profile, serum magnesium (Mg) and fasting serum glucose (FSG) were measured in 30 newly diagnosed normotensive type 2 diabetic patients chosen as cases (Group II) just before introducing any treatment, and was compared with that of 30 healthy controls (Group I). The serum magnesium was found to be significantly lower (p<0.001) and LDL-c was found to be significantly higher (p<0.01) in cases. The correlation analysis revealed a significant negative association of FSG to serum magnesium (r= -0.720), total cholesterol (r=-0.483) and a positive correlation to HDL-c (r=-0.440). However, serum magnesium showed a significant positive relation only with serum HDL-c (r =0.372, p<0.05). Serum magnesium and lipid fractions showed wide range of variation within the normal reference ranges in the newly diagnosed T2D subjects. Further large scale studies are needed to elucidate the association of serum magnesium with lipid profile changes. Estimation of serum magnesium level may prove useful in T2DM with normal or abnormal lipid levels or in those who are prone to develop dyslipidemia or certain complications associated with dyslipidemia.

RESUMO

The pathogenesis of diabetic retinopathy is still unclear. The relative role of duration of diabetes, glycemic and insulinemic status in the etiopathogenesis of retinopathy is to be clearly understood. Hypertension, hyperlipidemia, pregnancy and age at diagnosis have been thought to be factors associated with diabetic retinopathy. Taking advantage of the availability of a group of young lean, normotensive and generally normolipidemic subjects in Bangladeshi population, the present study was undertaken to investigate the relationship between insulin secretory capacity and microvascular damage in the pathogenesis of diabetic retinopathy. A total number of 91 diabetic subjects, diabetes diagnosed before the age of 30 years, were recruited form the out-patient Department, BIRDEM Hospital. Diabetic subjects recruited were new- to previously diagnosed cases with duration of diabetes around 8 years. Insulin secretory capacity was assessed by C-peptide and C-peptide was estimated by ELISA method. Urinary albumin was measured by Immunoturbidetric methods. The subjects were grouped on the basis of duration of diabetes and presence (DR) and absence (NDR) of diabetic retinopathy. Subjects were also divided on the basis of albumin-creatinine ratio (ACR) level. ACR level was observed sharply increased with the duration of diabetes and showed a peak after 8 years. In the ACR positive cases 95.25% of diabetic patient had retinopathy. Both retinopathic and ACR positive subjects had low insulin secretory capacity as evident by absolute C-peptide level and C-peptide glucose ratio. Retinopathy was found increased with generalized vasculopathy. Both microvasculopathy and retinopathy seemed to occur at around 8 years. Insulin secretory capacity in particular seemed to have predominant determinant effect in the etiopathogenesis of diabetic retinopathy.

RESUMO

This study was aimed to demonstrate the significance of free/total Prostate Specific Antigen (PSA) ratio in the diagnosis of prostatic enlargement. The study was carried out in a total number of 100 subjects, of which 58 had benign prostatic hyperplasia (BPH), 42 had carcinoma prostate and 50 were age matched control. The subjects were collected from Dhaka Medical College Hospital (DMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU). Venous blood (5ml) was drawn from each subject before digital rectal examination or pre-urethral manipulation for estimation of PSA. Final diagnosis was made by histopathological examination, specimen being obtained by transurethral resection of prostate (TURP), open prostatectomy and per rectal tru-cut biopsy with biopsy gun. The study showed a highly significant difference of serum PSA and free/total PSA ratio in differentiating BPH from carcinoma prostate. Free/total PSA ratio was highly significant in differentiating between BPH and carcinoma prostate (p<0.001) and carcinoma prostate and control (p<0.001). In the marginally elevated PSA, free/total PSA ratio reduced biopsy by 81-85% in BPH and carcinoma prostate respectively. The overall specificity, positive predictive value and efficiency of free/total PSA was much higher than that of total PSA in differentiating BPH from carcinoma prostate.
