Introduction:Neurogenic components, as neurotrophic factors and neuropeptides, are probably involved in the pathogenesis of atopic dermatitis (AD) with the neuroimmunocutaneous system as they modify the functions of immunoactive cells in the skin. Nerve growth factor (NGF) is the best-characterized member of the neurotrophin family. Both NGF and neuropeptides (NPs) may be associated with the disease pathogenesis.Aim:This study aims to evaluate the plasma level of NGF and NPs in AD patients and correlate them with the disease activity and nerve changes in the skin by electron microscopy.Materials and Methods:Plasma levels of NGF and vasoactive intestinal peptide (+VIP) were measured by an immunoenzymatic assay while plasma levels of calcitonine gene related peptide (CGRP) and neuropeptide Y (NPY) were measured by radioimmunoassay in 30 AD patients in comparison to 10 normal non-atopic controls. Electron microscopic study was done in 10 AD patients.Results:It has been found that there is significant increase of plasma levels of NGF and NPs in AD patients compared with controls. There is a positive correlation between the plasma levels of NGF and disease activity (correlation coefficient = 0.750, P<0.005). There is a significant correlation between the number of Schwann axon complex, evidenced by electron microscopic examination and plasma level of NGF in AD patients.Conclusion:It has been concluded that these neurogenic factors; NGF and NPs modulate the allergic response in AD, probably through interactions with cells of the immune-inflammatory component. NGF might be considered as a marker of the disease activity.
Objective: To find out the relation between Pro 12 Ala polymorphism of peroxisome proliferator-activated receptor gamma2 (PPAR-g2) gene with type 2 diabetes mellitus and the possible role of this gene polymorphism as a link between obesity and type 2 diabetes mellitus.
Subjects and Methods: Subjects of this study were classified into 3 groups: (15) Apparently healthy lean individuals (Group I), (15) obese non diabetic individuals (group II) and (24) patients with type 2 diabetes mellitus (group III). This group divided into: Diabetic non obese patients (12 patients) (Group IIIa) and: Diabetic obese patients (12 patients) (Group IIIb). The subjects were subjected to clinical examination, serum insulin level and estimation of PPAR-g2 gene polymorphism by Restriction fragment length polymorphism (RFLP) polymerase chain reaction (PCR).
Results: Frequency of Pro allele was significant increase in diabetic non obese patients& diabetic non obese patients when compared to control group (P= 0.048 and 0.003, respectively
Retinopathy in chronic HCV-infected patients undergoing treatment with combination of pegylated IFN-alpha and ribavirin therapy appears to be relatively low, and treatment cessation is rarely needed. Diabetic, hypertensive patients are at increased risk for IAR and are recommended to be ophthalmologically followed-up.
Objectives:
To assess the efficacy and safety of captopril, simvastatin, and L-carnitine as cardioprotective drugs in children with type 1 diabetes mellitus on different echocardiographic parameters, electrocardiographic parameter, lipid profile, and carotid intima–media thickness.
Methods:
This randomised controlled trial was conducted on 100 children with type 1 diabetes mellitus for more than 3 years during the period from September 2018 to June 2020. Fifty healthy children of matched age and sex served as a control group. The patients were randomly assigned into four groups (25 children each): no-treatment group who received no cardioprotective drug, simvastatin group who received simvastatin (10–20 mg/day), captopril group who received captopril (0.2 mg/kg/day), and L-carnitine group who received L-carnitine (50 mg/kg/day) for 4 months. Lipid profile, serum troponin I, carotid intima–media thickness, and echocardiographic examinations were performed on all included children before and after the treatment.
Results:
Total cholesterol and low-density lipoprotein were significantly decreased in children who received simvastatin or L-carnitine. Triglycerides significantly decreased only in children who received simvastatin. High-density lipoprotein significantly increased in simvastatin and L-carnitine groups only. Serum troponin I decreased significantly in all the three treatment groups. Carotid intima–media thickness showed no significant change in all treatment groups. Echocardiographic parameters significantly improved in simvastatin, L-carnitine, and captopril groups.
Conclusion:
Captopril, simvastatin, and L-carnitine have a significant beneficial effect on cardiac functions in children with type 1 diabetes mellitus. However, only simvastatin and L-carnitine have a beneficial effect on the lipid profile. The drugs were safe and well tolerated.
Clinical trial registration: The clinical trial was registered at www.clinicaltrial.gov (NCT03660293).
