Studying the Effect of Methotrexate Alone Versus Methotrexate and Vitamin D on the Cardiovascular Risk of Psoriatic Patients

Study Purpose

The prevalence of cardiovascular risk in psoriasis has been reported in previous studies.Various studies have also shown that systemic treatments for psoriasis, including methotrexate, may significantly decrease this cardiovascular risk. We proposed that the addition of vitamin D may not only improve the therapeutic effect of various treatment modalities but also increase its effect on decreasing the cardiovascular risk in psoriasis. So our aim of work is to assess the Clinical improvement and cardiovascular risks in psoriatic patients after treatment with methotrexate alone with the dose of 0.2-0.5 mg/kg/week for three months in comparison to combined methotrexate with the same dose and vitamin D injection with the dose of 200,000 IU per month for 3 months. Each patient will do the following before starting treatment& after 3 months: 1. Fasting blood sugar, 2 hours postprandial and glycosylated hemoglobin 2. Liver and Kidney function tests. 3. Cardiovascular risk assessment by measuring the intima media thickness of carotid arteries using Carotid duplex and High sensitive C reactive protein measuring by particle-enhanced immunonephelometry on autoanalyzer. 4. Lipid profile (HDL, LDL, cholesterol and triglycerides). 5. Calculate body mass index and measure blood pressure 6. Albumin /creatinine ratio 7. Serum vitamin D level. Clinical response will be evaluated by Psoriasis Area and Severity index (PASI) & Psoriasis Disability Index (PDI) scores before and after 3 months of treatment

Recruitment Criteria

Accepts Healthy Volunteers

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

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, 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.


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.
