Serum resistin and lipid profile in primigravida females with and without preeclampsia: An analytical cross-sectional study.

OBJECTIVE: To measure and compare the serum levels of resistin and lipid profile parameters in primigravida females with and without preeclampsia. Methods: The analytical cross-sectional study was conducted at the Department of Physiology and Cell Biology, University of Health Sciences, Lahore, Pakistan, from 2018 to 2020, and comprised primigravida females having gestational age 30-36 weeks. Those with preeclampsia constituted group 1, while normotensive females constituted group 2. All the participants were subjected to detailed history and general physical examination. Serum resistin levels were measured by enzymelinked immunosorbent assay, and lipid profile parameters were measured using the colorimetric method. Data was analysed using SPSS 20. RESULTS: Of the 80 women, 40(50%) were in group 1 with mean age 23.07±2.10 years and mean gestation age 33.45±2.30 weeks. There were 40(50%) women in group 2 with mean age 23.02±2.11 years and mean gestational age 34.45±1.75 weeks. Mean serum resistin was significantly higher in group 1 compared to group 2 (p<0.02). Mean levels of lipid parameters were significantly different between the groups (p˂0.05). Conclusion: Preeclampsia was found to be associated with higher levels of resistin and lipid parameters compared to normal pregnancy.

Plasma surfactant Protein-D levels in healthy subjects and COPD patients.

OBJECTIVE: To compare plasma surfactant protein-D levels in healthy smokers and Chronic obstructive pulmonary disease patients. METHODS: The comparative study was conducted at the University of Health Sciences, Lahore, Pakistan, from January to December 2015, and comprised chronic obstructive pulmonary disease patients and healthy smokers of either gender aged 40-80 years. Plasma surfactant protein-D levels of male and female subjects were estimated and compared with lung function and tobacco exposure. Blood samples were collected after complete history, physical examination and spirometry. Plasma levels were measured using enzyme-linked immunosorbent assay. Plasma cotinine levels were also measured for the determination of tobacco as well as biomass exposure along with pack years. SPSS 20 was used for data analysis.. RESULTS: Of the 84 subjects, there were 42(50%) patients and as many controls. Both groups had 21(50%) males and as many females. There was no significant difference in the plasma surfactant protein-D levels of males and females in the patient group compared to their counterparts in the control group (p>0.05). Females developed the disease at a younger age compared to males (p=0.04). There was no significant difference in terms of pack-years and cotinine levels between the groups (p>0.05) and lung function showed greater deterioration in the females compared to males with similar tobacco exposure (p<0.05).. CONCLUSIONS: The gender did not affect plasma surfactant protein-D levels.

Plasma Surfactant Protein-A Levels In Healthy Subjects And Chronic Obstructive Pulmonary Disease Patients.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is the leading cause of morbidity and mortality across the globe. Currently, there is a dearth of biomarkers which can accurately diagnose and evaluate the prognosis of the disease. Systemic Surfactant Protein- A (SP-A) levels are generally higher in smokers compared to non-smokers as well as elevated in COPD patients as compared to controls. The objective of the study was to estimate and compare plasma surfactant protein-A levels in male and female COPD patients and healthy subjects and to evaluate the role of SP-A as a possible bio-marker for COPD patients. METHODS: A Comparative study, conducted at the department of Physiology & Cell Biology, University of Health Sciences, Lahore between August 2013 and April 2015. A total of 84 subjects of both sexes between 30-80 years of age were included in this study. Subjects were taken from local community and were divided into four groups (A- D). COPD was diagnosed on the basis of relevant history and spirometry showing post bronchodilator FEV1/FVC <0.70. RESULTS: Plasma SP-A levels were not different between controls and COPD patients and between male and female COPD patients. However, SP-A levels were directly correlated with cotinine levels (r= 0.503, p=0.001). Female patients were usually more symptomatic than males and developed COPD at an earlier age compared with male patients. CONCLUSION: Plasma SP-A levels were not significantly different between groups. Plasma cotinine levels (an indication of the tobacco use) were positively correlated with plasma SP-A levels in study subjects. Female patients developed COPD at an early age compared to male counterparts with similar tobacco exposure.
