Study summary

The goal of this observational study is to evaluate nailfold capillaroscopic changes in patients with psoriasis and to assess their correlation with disease severity. The study will also explore differences in capillaroscopic findings across different clinical types of psoriasis and skin phototypes (Fitzpatrick classification). The study will include patients diagnosed with psoriasis attending dermatology outpatient clinics. Participants will undergo clinical assessment and nailfold capillaroscopy to detect microvascular changes.

Interventions

  • OtherNailfold Capillaroscopy

    Participants will undergo nailfold capillaroscopy using a USB digital capillaroscope to assess microvascular changes in psoriatic patients. Clinical assessment including PASI score and evaluation of nail involvement will also be performed.

    Also known as: Dermoscopy (if used for nails)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 31, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
