Leprosy reduces quality of life of affected persons. Oxidative stress caused by reactive oxygen species may play a vital role in the pathogenesis of leprosy. This study evaluated anthropometric indices, fasting plasma glucose (FPG), lipid profile, total antioxidant capacity (TAC), total plasma peroxide (TPP), oxidative stress index (OSI), malondialdehyde (MDA), glutathione (GSH) and 8-hydroxy-2-deoxyguanosine (8-OHdg) in leprosy patients. Sixty test participants of both genders, aged 18-65years and diagnosed of multibacillary leprosy and 30 apparently healthy controls were consecutively recruited for this study. The test participants comprised of 30 patients on multidrug therapy (MDT) and 30 patients relieved from therapy (RFT). Body mass index (BMI), Waist-hip ratio (WHR), FPG, lipid profile, TAC, TPP, OSI, MDA, GSH and 8-OHdg were determined using appropriate methods. Data were analyzed using Analysis of variance; p<0.05 was considered statistically significant. The MDT group had significantly lower BMI (p = 0.0001), Total cholesterol (p = 0.001), HDL-C (p = 0.019), LDL-C (p = 0.005), TAC (p = 0.0001) and higher TPP (p = 0.001), MDA (p = 0.0001), OSI (p = 0.005) and 8-OHdg (p = 0.035) compared to the controls. The RFT group had significantly lower BMI (p = 0.001) Total cholesterol (0.0001), HDL-C (p = 0.006) LDL-C (p = 0.0001), TAC (p = 0.001) and higher WHR (p = 0.010), VLDL-C (p = 0.035), TG (p = 0.023) Atherogenic index of plasma (p = 0.0001) and TPP (p = 0.001), MDA (p = 0.0001) compared to the control group. GSH levels correlated negatively with duration of treatment (r = -0.401, p = 0.028). This study has shown that there is oxidative stress in multibacillary leprosy patients irrespective of drug treatment status. This study also shows that leprosy patients relieved from treatment may be susceptible to cardiovascular events. Antioxidants supplementation may be beneficial in the treatment of leprosy and clinical follow up on patients relieved from treatment may also be necessary to monitor health status and prevent development of cardiovascular events.

Effect of combined calcium, magnesium, vitamin C and E supplementation on seminal parameters and serum oxidative stress markers in fructose-induced diabetic Wistar rats.

Deleterious effects of diabetes on seminal quality, serum metals and antioxidants have been confirmed. This study evaluated the effect of combined calcium, magnesium, vitamin C and E supplementation on seminal parameters, serum total antioxidant capacity (TAC), nitric oxide (NO), malonyldialdehyde (MDA), calcium and magnesium in fructose-induced diabetic rats. Thirty rats were grouped into non-diabetic controls, diabetic controls, diabetic rats given vitamin E + C, calcium + magnesium and vitamin E + C + calcium + magnesium. The analytes were evaluated using standard methods. Statistical significance was set at  < .05. The diabetic controls had significantly higher MDA ( = .036) but lower ( = .0001) TAC, calcium, magnesium, sperm count, and %motility than the non-diabetic controls. The Vitamin C + E group showed the greatest improvement as they had the highest values of seminal parameters compared to other supplemented groups. Combined Vitamin C + E supplementation may provide better ameliorative benefits than a combination of Vitamin C, E, calcium and magnesium in diabetics.

Seminal Oxidative Stress Markers, Calcium, Magnesium, and Semen Profile of Infertile Diabetic and Nondiabetic Nigerian Men.

Int J Appl Basic Med Res 2019 Jul-Sep;9(3):159-164

Department of Medical Laboratory Sciences, Faculty of Allied Medical Sciences, College of Medical Sciences, University of Calabar, Calabar, Nigeria.

Context: Oxidative stress, vitamin, and macroelement deficiencies have been implicated in male infertility. It is unknown if diabetes mellitus with its attendant increased oxidative stress makes the seminal quality of the diabetic infertile men worse compared to their nondiabetic counterparts.

Aims: The study investigated semen parameters, seminal plasma calcium, magnesium, Vitamins C and E, and total antioxidant capacity (TAC) in diabetic and nondiabetic infertile men.

Settings And Design: This was a cross-sectional study involving 30 infertile men with type 2 diabetes, 30 infertile nondiabetic men and 30 fertile men.

Subjects And Methods: Fasting plasma glucose, glycated hemoglobin, seminal plasma calcium, magnesium, TAC, Vitamin C, Vitamin E, semen analysis, and cultures carried out using the standard procedures.

Statistical Analysis Used: Data were analyzed by the analysis of variance and Student's -test; the level of significance was set at < 0.05.

Results: Both infertile groups had significantly lower ( < 0.0001) sperm count, percentage motility, TAC, Vitamin E and C, magnesium and calcium when compared to the fertile group. However, there was no statistically significant difference ( > 0.05) in the mean values of these parameters among the two infertile groups. The infertile men had a significantly higher ( = 0.034) frequency of bacterial isolates compared to the fertile men. was the most frequent organism isolated.

Conclusions: Seminal calcium, magnesium, TAC, and Vitamin E and C were lower in both infertile diabetic and nondiabetic men as compared to that of fertile men, but the levels of these analytes were comparable in the infertile diabetic and nondiabetic men.

Thyroid hormones and prolactin levels in infertile women in southern Nigeria.

J Clin Diagn Res 2015 Mar 1;9(3):OC13-5. Epub 2015 Mar 1.

Principal Medical Laboratory Scientist, Department of Chemical Pathology, University of Calabar Teaching Hospital , Calabar, Nigeria .

Introduction: Human infertility is a complex global health problem. It has multiple social consequences which are especially profound for thyroid hormones in infertility with the aim of determining the degree of association of thyroid hormones with hyperprolactinemia in our population.

Materials And Methods: The serum levels of prolactin, T3, T4 and TSH were determined in 90 hyperprolactinemic infertile women, 90 normoprolactinemic infertile women and 50 fertile women. The hormones were assayed using Enzyme Linked Immunosorbent Assay kits.

Statistical Analysis: Analysis of variance and Pearson's correlation were used to analyze the data, with the significant p-level set at 0.05.

Results: A significantly higher mean serum prolactin and TSH were observed among the infertile groups compared to the fertile controls (p<0.05). The mean serum T3 and T4 were significantly lower in the hyperprolactinemic infertile women compared to the fertile controls (p<0.05). The mean TSH and T3 of normoprolactinemic infertile women and controls were comparable (p>0.05). However, the mean T4 was significantly lower in normoprolactinemic infertile women compared to the fertile controls (p<0.05). In all the groups, TSH correlated inversely with T3 and T4, while T3 correlated positively with T4. It was only in the control group that prolactin correlated positively and significantly with TSH.

Conclusion: It is therefore concluded that hyperprolactinemia with thyroid dysfunction may be a major contributory hormonal factor in infertility among infertile women and as such, estimation of prolactin, T3, T4 and TSH should be included in the workup for infertile women especially those with hyperprolactinaemia.
