ABSTRACT
Background:Insulin resistance (IR) is a metabolic state characterized by a decrease in cellular ability to respond to insulin signaling, which contribute to pathophysiological mechanism in the development of all metabolic complication of polycystic ovary syndrome (PCOS). The aim of thestudy wasto match categorized values of patient’s biochemical predisposing factors for polycystic ovaries such as insulin with change in follicular sizes as determined by sonography following CLOMID inducement therapy. Methods:This experimental study was carried out in Anambra State, Nigeria from June 2018 to May 2021.Those included in the study were women of child bearing age (18 to 45 years) for both groups. The ultrasound examinations and insulin levels measurements were performed on each subject and data such as follicular sizes, insulin levels before and after treatment were recorded. Obtained data were analyzed using both descriptive and inferential statistical tools. Results:There were no statistically significant mean differences in the insulin levels (t=1.16, p=0.81) and maximal follicular size (t=0.39, p=0.70) of women with and without polycystic ovary who had successful and failed ovulation before the clomid treatment. Both the insulin level (t=2.85, p<0.01) and follicular size (t=4.88, p<0.01) showed statistically significant mean differences. There was significant difference in insulin (F=7.55, p<0.01), with the control having the lowest insulin concentration. Conclusions: There were statistically significant mean differences in the insulin level and follicular size in women with polycystic ovary after clomid treatment. Therefore, clomiphene citrate inducement triggers increase in serum concentration of insulin.
ABSTRACT
Background: Malaria is a mosquito-borne public health problem which alters the blood counts, haptoglobin level and serum lactate dehydrogenase (sLDH) activity of the infected individuals. Some of the alterations are associated risk factors in malaria pathology. This study aims at elucidating changes in blood counts, sLDH activity and haptoglobin level in malaria infected subjects seen in a Tertiary Health Institution in Nnewi, as search for associated risk factors in malaria pathology.Methods: This cross sectional study enrolled 270 age matched subjects between 18-65 years. The test group (200) who tested positive to P. falciparium was placed into two groups based on their parasite counts with cut-off of ≥1000 parasites x 109/L. Group one (100) had counts above the cut-off and group two (100) below. The control (70) was aparasitemic. The demographic data were noted and 4mls of blood drawn. 2mls in K3EDTA was for FBC testing using Mythic 22 hematology analyzer, and remaining dispensed into plain tubes was for sLDH assay by kinetic method and haptoglobin by ELISA technique.Results: The HCT, Hb, RBC and Platelet count of test were progressively significantly lowered (p=0.001) compared to control, with an intra-significant difference among the 3 groups (p<0.05), also the parameters were found to have an inverse significant relationship (p=0.001) to the parasite counts. This trend was also seen with haptoglobin while reverse was the case with LDH activity which rather increased significantly (p = 0.000) at opposite direction as parasite density increases.Conclusions: This study show that the degree of intravascular haemolysis is directly influenced by the parasite density, this portends that high endemicity and perennial parasiteamia in the study area could cause chronic anaemia and thrombocytopenia in the population studied.
