Nailfold Capillaroscopy and Clinical Applications in Systemic Sclerosis

Area of Science:

• Ophthalmology and Dermatology
• Rheumatology
• Vascular Biology

Background:

• Systemic sclerosis (SSc) affects microcirculation, impacting diagnosis and prognosis.
• Early detection of SSc and its complications, like digital ulcers (DU), is crucial.
• Capillary microscopy is a non-invasive technique to visualize microvascular changes.

Purpose of the Study:

• To review the principles and applications of capillary microscopy in SSc.
• To evaluate the utility of capillaroscopy as a biomarker for SSc.
• To focus on the association between capillaroscopy findings and the prediction of digital ulcers (DU) in SSc patients.

Main Methods:

• Review of existing literature on capillary microscopy in SSc.
• Analysis of studies correlating capillaroscopy findings with SSc diagnosis.
• Examination of research linking capillaroscopy to the development of DU.

Main Results:

• Capillary microscopy effectively visualizes microcirculatory abnormalities in SSc.
• Specific capillaroscopic patterns are associated with SSc diagnosis and severity.
• Evidence suggests capillaroscopy can aid in predicting the risk of DU.

Conclusions:

• Capillary microscopy is a valuable tool for early SSc diagnosis.
• It shows promise as a biomarker for predicting DU in SSc.
• Further research can solidify its role in SSc management.
