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

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.
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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Psoriasis is a quite common chronic, inflammatory immune-mediated skin disease affecting about 2% of the population . Also psoriasis is a strong risk factor for the development of several comorbidities of which the most common is psoriatic arthritis (PsA). The presence of cutaneous psoriasis indicates a high risk for developing PsA. Studies conducted in dermatology clinics have shown a high prevalence of undiagnosed PsA in psoriasis patients , therefore identifying soluble biomarkers for PsA in psoriasis patients may help in early diagnosis, and thereby prevent disability and improve quality of life . Mac 2 binding protein [M2BP] is thought to be a marker of synovial cell activation and joint destruction .M2BP may be involved in the pathogenesis of PsA . Recently, with the introduction of new medications and wider use of musculoskeletal ultrasound (US) imaging in clinical practice, the possibility of earlier US diagnosis in patients with psoriasis in the pre-clinical phase of PsA has been examined.
: Group 1
45 patients with cutaneous psoriasis with no musculoskeletal manifestations.
: Group 2
45 patients with psoriatic arthritis fulfilling CASPAR criteria of PsA
: Group 3
45 patients with subclinical psoriatic arthritis (patients with cutaneous psoriasis and musculoskeletal manifestations but not fulfilling CASPARcriteria of PsA).
: Group 4
45 sex and age matched healthy controls
Diagnostic Test: - serum level of Mac 2 binding protein
Serum levels of Mac 2 binding protein will be measured for all the study subjects using Enzyme-Linked Immuno sorbent Assay (ELISA). 2 ml of venous blood will be collected from patients and controls under complete aseptic conditions in a plain tube. Sample will be allowed to clot for 15-30 min at room temperature and then centrifuged at 2500 rpm for 10-15 min. Serum will be separated and stored at -20 C or lower till time of assessment.
Device: - musculoskeletal ultrasound
MSUS examination will be performed for patients of all groups and control group.Gray scale (GSUS) and power Doppler (PDUS) at joints levels and entheses will be performed with the same transducer of My Lab Seven Crystalline esaote machine.
