Glucose Trnsporter and PEDF in Psoriasis

Study Purpose

Psoriasis is a chronic relapsing cutaneous immune mediated inflammatory disease(IMID). In which there are skin lesions characterized by erythema, thickness and scale formation with different size from a pinhead to 20 cm in diameter. Prevalence of psoriasis is 2% to 4% worldwide. Psoriasis occurs at any age with two peaks: between 15-20 years and between 55-60 years. Women are presented with psoriasis at younger age than men ,but with less severity. lesions usually present on knee, elbow, scalp and sacral region this may be attributed to higher traumatic incident . Psoriasis vulgaris is the most common type, and accounts 90% of cases. Patients with psoriasis vulgaris present with pain, itching and bleeding from skin lesions. There are many theories for psoriasis pathogenesis: angiogenesis, decrease in apoptosis of keratinocyte, hyperproliferation , alteration of cell to cell adhesion and immune-mediated inflammation. Patients with immune mediated inflammatory disease (IMID) are susceptible to develop diabetes mellitus, metabolic syndrome, hyperlipidemia, and hypertension.A previous study found that psoriatic patients are more susceptible to type 2 diabetes compared to control. Glucose transporter type 1(GLUT1) is upregulated in psoriatic patient attributed to angiogenesis and execessive cell proliferation in those patients .Also expression of GLUT 1 is found high with hyperglycemia . A study reported that GLUT 1 density in placenta of women with gestational diabetes was found to be two folds higher than control. Pigment epithelium derived factor (PEDF) has antiangiogenic effect. Topical application of PEDF on mouse model of psoriatic disease helps in reduction of skin proliferation and angiogenesis. GLUT 1 overexpression was found to be associated with decrease in PEDF expression in diabetic retinopathy. In view of that we will compare the level of GLUT 1 gene in psoriatic patients and psoriatic patients with diabetes, as well as healthy control, and detect the effect of PEDF on GLUT 1 expression in vitro using human keratinocytes cell line .

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04242082
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

: patients with psoriasis vulgaris only

: patients with psoriasis vulgaris and type 2 diabetes mellitus

: healthy control

Interventions

Diagnostic Test: - GLUT 1 gene expression

GLUT 1 gene expression will done on blood samples taken from three groups using real time PCR. Pigment epithelium derived factor will used on keratinocytes cell line and compare GLUT 1 gene expression before and after treatment.
