Serum adiponectin and metabolic profile in women with polycystic ovarian syndrome in relation to body mass index

Background: Polycystic ovarian syndrome is a common endocrine disorder which affects approximately 5-10% of women in reproductive age. It is both a reproductive endocrinopathy and a metabolic disorder.Methods: 160 women aged 18 to 40 years attending obstetrics and gynaecology clinic at Federal medical centre, Owerri, Imo State Nigeria were recruited and divided into 2 groups (women diagnosed with PCOS using Rotterdam criteria and control) of 80 participants each. Anthropometric data were collected, and participants categorized into 3 based on BMI. Fasting blood samples was collected for biochemical analyses. Data were analyzed using the Statistical Package for Social Sciences SPSS version 23.0, and level of significance set at p<0.05.Results: The mean serum levels of adiponectin and high density lipoprotein (HDL-C) were significantly lower while fasting plasma glucose, serum insulin, homeostatic model assessment for insulin resistance, total cholesterol, low density lipoprotein (LDL-C), very low density lipoprotein (VLDL-C) and triglyceride were significantly higher in women with PCOS when compared with the control (p<0.05) as well as in obese when compared with normal weight women with PCOS (p<0.05). BMI negatively correlated with serum adiponectin and HDL-C, but positively correlated with FPG, insulin, HOMA-IR, TC, TG, LDL-C and VLDL-C in women with PCOS (p<0.05).Conclusions: This study highlights the prevalent biochemical and metabolic derangements in PCOS patients and was more evident in the obese and overweight patients. Early detection with subsequent application of preemptive measures including lifestyle modifications are therefore essential in the management of PCOS patients

Comparison of serum levels of calcium and magnesium among preeclamptic and normotensive pregnant women at Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria

Background:Despite numerous studies, the exact aetiology of pre-eclampsia remains unknown. Some studies have shown that supplementation of calcium and magnesium could ameliorate the effects of pre-eclampsia. The objective of this study was to compare the calcium and magnesium levels in the serum of Nigerian women with or without pre-eclampsia.Methods:In this study, serum calcium and magnesium levels were determined using atomic absorption spectrometry in 54 patients and 48 healthy normotensive pregnant women. The mean, standard deviation, Student’s‘t’ test and Pearson correlation were employed.Results:Serum calcium was significantly lower in patients than controls (9.17 ± 0.6 vs. 7.22 ± 0.5 mg/dl. P <0.001) (t test). Plasma Magnesium was significantly lower in patients than controls 13.19 ± 1.1 vs. 9.81 ± 0.7 mg/dl. P <0.001). The systolic and diastolic blood pressure showed significant inverse correlation with both calcium and magnesium (P<0.01).Conclusion:There was significant reduction in the levels of calcium and magnesium in patients with pre-eclampsia. Dietary supplementation of these trace elements may help to prevent pre-eclampsia

The levels of testosterone, zinc, manganese and selenium in type 2 diabetic patient in South-Eastern Nigeria

Background: This study is aimed at evaluating the levels of some trace elements and testosterone, and to ascertain their possible association in type 2 diabetes mellitus.  Methods: Ninety male type 2 diabetic subjects and forty five apparently healthy non-diabetic male individuals were recruited into this study. The control group was matched for age with the study subjects and they were all within the age range of 30-67 years. Fasting Plasma Glucose (FPG), testosterone, trace elements (zinc, selenium, manganese), Body Mass Index (BMI) were determined.Results: This study showed significant decreases in the levels of trace elements (Zn, Se, and Mn) with a concomitant decrease in the levels of testosterone in type 2 diabetic patients (P <0.001). This findings were further strengthened by the strong positive correlation between testosterone and these trace elements (P <0.05).Conclusion: This suggests that low testosterone level might be as a result of low trace elements considering their role in testosterone production. Therefore, trace elements supplementation is recommended

Evaluation of nephrotoxic effect of lead exposure among automobile repairers in Nnewi Metropolis

Background:Lead toxicity is one of the most common occupational hazards that affect several organs of the body, kidney inclusive. Auto repairers are exposed to lead in petrol, radiator, leaded battery, lead soldering wire, and spray paints, thus this study was designed to evaluate lead-induced nephrotoxic effect among automobile repairers.Methods:A total of 80 male subjects within the age range of 20 and 65 years were recruited for this study. 50 subjects were occupationally exposed automobile repairers, of which 15 were electricians, 21 mechanics and 14 panel beaters/spray painters, whereas 30 were non-exposed students and staff from Nnamdi Azikiwe University, Nnewi campus. Blood sample was collected from these individuals and their blood lead levels were determined alongside creatinine, urea, uric acid, sodium, potassium, chloride and bicarbonate.Results:The results showed that the mean levels of blood lead is significantly higher in automobile repairers than in control group (P 0.05). The evaluation of the renal function markers show that, there were significant increases in the mean serum concentration of creatinine, urea, and uric acid in the study group compare to the control subjects (P 0.05).Conclusion:Findings from this study show that blood lead level is high among automobile repairers above CDC recommended level for adults. This high blood lead level among automobile repairers may be responsible for raised levels of renal markers which may eventually lead to their renal damage.

Effect of moderate - vigorous intensity physical exercise on female sex hormones in premenopausal university students in Nnewi, Nigeria

Background: Sedentary lifestyle and diseases associated with it is on the increase in our communities, state and country as a whole. The objective was to determine the effect of exercise on ovarian reserve status of the participants using day 3 FSH, LH and estrogen values and the ovulatory status of the participants using day 21 progesterone values. Methods: The study was a prospective comparative study. A total of 30 participants were recruited for this work. They were divided into 2 groups: 15 subjects that did exercise for 1 month and 15 controls that didn’t do any form of exercise. Baseline blood samples were collected from the two groups on day 3 and day 21 of the menstrual cycle. The subjects started exercise on day 1 of the next menstrual cycle. Blood samples were collected from the subjects and control on day 3 and day 21 of the next menstrual cycle. Results:There was significant reduction in weight and therefore BMI of the study group compared to control group and study group baseline after one month of exercise (P<0.05). There were no significant differences in the baseline levels of Estrogen, FSH, LH and progesterone between the subjects and control groups before the exercise, but after 1 month of exercise, there were significant differences in the levels of estrogen, FSH, LH and progesterone in these groups (P<0.01). Among the study group there were significant differences in the baseline and final levels of Estrogen, FSH, LH and Progesterone (P<0.01). Conclusions: The hormonal pattern shows that moderate-vigorous exercise may increase the responsiveness and sensitivity of the follicles to FSH and LH with attendant increase in ovulatory status of young females.

Effect of omega-3 supplementation on serum adiponectin and fertility hormones in women with polycystic ovarian syndrome

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age with prevalence of about 4%–20%. Aim: This study aims to evaluate serum adiponectin and fertility hormones in women with PCOS, and the subsequent effect of omega-3 supplementation. Subjects and Methods: One hundred and fifty women aged 18–40 years were assigned into groups A and B comprising women with PCOS and control, respectively. Group A was further subdivided into groups 1 and 2 receiving omega-3 and placebo daily for 12 weeks, respectively. Blood samples were collected before and after 12 weeks of supplementation for analysis of adiponectin, follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, prolactin, estradiol, progesterone, and sex hormone binding globulin (SHBG). Statistical Package for Social Sciences (SPSS) version 23.0 was used for data analysis, and the level of statistical significance was set at P < 0.05. Results: Serum adiponectin, progesterone, and SHBG were significantly lower while FSH, LH, testosterone, prolactin, and estradiol were significantly higher in women with PCOS when compared with the control (P < 0.05). Adiponectin and progesterone levels increased significantly while FSH, LH, testosterone, prolactin, and estradiol levels decreased significantly after 12 weeks of omega-3 supplementation when compared with the levels at baseline as well as when compared with those on placebo (P < 0.05). Statistical Package for Social Sciences (SPSS) version 23.0 was used for data analysis. Conclusion: Omega-3 may be beneficial in improving certain hormonal alterations in women with PCOS. Omega-3 supplements may therefore be used as part of the regimen in the management of patients with PCOS
