Abstract

To study the serum IGF-1 level for prediction of growth hormone deficiency and its role in the diagnosis of short stature in children and adolescents. A study was conducted on forty four (44) short children with growth hormone deficiency. Children were classified into Group I thirty five (35) prepubertal children and Group II (9) patients who entered puberty. In addition to forty (40) apparently healthy children as control group, also were divided into group I control(29) prepubertal &group II (11) pubertal . IGF-1,GH ,Thyroid function ,serology for celiac disease , Hb level ,bone age were done for all patients. IGF-1 and basal GH level (without provocative test) were done for control . There was a significant low difference between the serum IGF-1 level in the patients of group I in comparison to their serum level in control group I {(90.98±23.69) (121.83±23.69) (p<0.05)} . While there was no such difference between the serum IGF-1 level in the patients of group II in comparison to their serum level in control group II {(184.59±196.52) (285.91±68.89) (p<0.05)}. This study shows that IGF-1 level is low compared to control in short GH deficient children who did not enter puberty, while it is less significant in children and adolescents who entered puberty. So IGF-1 is a suitable parameter to predict GH deficiency in short prepubertal children in whom GH deficiency was found by GH provocative testing. But this test is less reliable in children who entered puberty.

Abstract

Background: Obesity is highly associated with insulin resistance and increased risk of type 2 diabetes and cardiovascular disease. Visfatin is adipocytokines that is highly expressed in visceral fat. Its expression in visceral fat is hyperglycemia in insulin deficient diabetes. Objective: To study the visfatin level in type 2 diabetes mellitus patients and its relation with obesity and insulin resistance.Patients and methods: This study was done in national diabetes center(NDC),AL -Mustansria University and AL –Yarmok Hospital Teaching ; on a total (120) individuals age range from (33-60) years. ( 80) patient type 2 diabetes nephropathy, (40) healthy controls . The enrolled patients were divided to three groups according to BMI ,data collection about age, sex ,WHR, BMI and blood samples to estimate serum visfatin levels, fasting plasma glucose(FPG), glycated hemoglobin(HbA1c), lipid profile (TC,TG,HDL-C,and LDL-C), fasting C-Peptide ,and fasting insulin level Furthermore insulin resistance parameters calculated from Homeostasis Model Assessment 2- insulin Resistance were calculated using HOMA2-Calculator software downloaded freely .Results: The mean FPG,HbA1c, C-Peptide level, fasting insulin level ,HOMA2IR and visfatin level show statistically significantly increased in diabetic patients when compared with control subjects. Serum visfatin level was significantly increased with BMI increased groups. Visfatin level was increased in HOMA2-IR =>3 when compared with HOMA2-IR <3 in diabetic patients. Visfatin level show significant positive coorelation with BMI, WHR,FPG, HbA1c, fasting insulin level , HOMA2-IR , TC,TG,and LDL-C in diabetic patients when compared with control subjects ,and negative correlation between serum visfatin level and HDL-C in diabetic patients when compared with control subjects . Conclusion: Obesity and Insulin resistance play an important role in the pathophysiology of type 2 diabetes mellitus. Elevated visfatin level in diabetic patients with obesity features of insulin resistance are believed to result in distance clinical characteristics and complications such as atherosclerosis.
