Serum Leptin levels in newly diagnosed Epileptic Patients.

Objectives: To compare leptin levels in newly-diagnosed treatment-naive epileptic patients and healthy controls. METHODS: This case-control study was conducted from January 10 to September 15, 2022, at the Dow University of Health Sciences, Karachi, and comprised newly-diagnosed epileptic patients age 12-35years who had no comorbidity. The subjects were enrolled from the Neurology out-patient department of Civil Hospital, Karachi. Healthy individuals matched for age, gender and body mass index were also enrolled as controls. Blood samples were collected between 8am and 10am for the evaluation of serum leptin levels using enzyme-linked immunosorbent assay. Data was analysed using SPSS 26. RESULTS: Of the 100 subjects, 64(64%) were males and 36(36%) were females. There were 50(50%) cases with mean age 19.34±5.65 years, and 50(50%) controls with mean age 19.76±5.67 (p=0.614). 100% of 50 individuals in control group did not have any family history of epilepsy,while 18% of cases (9) reported a positive family history. Mean leptin level in cases was 31.03±19.37 compared to 5.25±4.03 in the controls (p<0.05). CONCLUSIONS: Serum leptin levels were elevated in newly-diagnosed epileptic patients compared to healthy controls.

Oxidative stress in polycystic ovary syndrome: a case-control study.

OBJECTIVE: To compare the serum levels of biochemical and oxidative stress markers i.e., malondialdehyde (MDA) and paraoxonase-1(PON1) in polycystic ovary syndrome (PCOS) patients and healthy female individuals of reproductive age group (18-40 years). METHODS: This case-control study was conducted in Dow University of Health Sciences (DUHS), Karachi from June 2019 to October 2020. Seventy Subjects including 35 PCOS patients that have primary subfertility problem (cases) and 35 healthy and fertile females (controls) were recruited. Serum samples were collected for analysis of insulin, sex hormone-binding globulin, testosterone, fasting blood glucose and lipid profile. PON 1 and MDA levels were estimated by ELISA. Comparison between the two groups was done using independent t-test. RESULTS: The patients had significantly increased mean body mass index (28.5+4.6 kg/m2 vs 25.7+4.5 kg/m2, p=0.014), systolic (129.6±13.9 mm of Hg vs 113±7.7 mm of Hg, p<0.001) and diastolic (78.7±8.8 mm of Hg vs 74.6±6.7 mm of Hg, p=0.032) blood pressures compared to controls. The high-density lipoprotein cholesterol levels were significantly lower in PCOS (42.2±8.6mg/dl) than controls (48.8±11.8mg/dl, p=0.009, p=0.009). Serum insulin (14.3±5.8 uIU/mL) vs (10.0±5.2 uIU/mL), p=0.002 and testosterone levels (1.3±0.9 nmol/L) vs (0.82±0.3 nmol/L), p<0.001 were significantly higher whereas sex hormone binding globulin (SHBG) levels (35.2±19.7nmol/L vs 58.8±31.0 nmol/L) were significantly lower in patients than healthy controls (p<0.001). Both oxidative stress markers, paraoxonase 1 (7.7±2.4 vs 6.4±2.6 µg/mL, p=0.04) and malondialdehyde (2.5±1.0 vs 1.9+0.51µg/mL, p=0.034) levels were significantly elevated in PCOS patients than controls. No significant correlation was found between dietary habits and life style between cases and controls. CONCLUSIONS: The study reported significantly elevated levels of oxidative stress markers in PCOS patients.
