Digital thermometry for Raynaud's disease (RD) showed poor specificity. Objective instrumental data did not reliably distinguish between symptomatic and asymptomatic individuals, indicating limitations in diagnosing RD using this method.

Area of Science:

  • Vascular Medicine
  • Medical Diagnostics
  • Biophysics

Background:

  • Raynaud's disease (RD) is characterized by reduced finger temperature and delayed recovery.
  • Thermometry offers an objective method to evaluate these temperature changes.
  • Current diagnostic approaches may benefit from enhanced objective measures.

Purpose of the Study:

  • To assess the diagnostic value of digital thermometry in identifying Raynaud's disease.
  • To compare instrumental thermometry findings with clinical presentation in subjects with and without RD symptoms.
  • To determine if objective thermometric parameters can reliably differentiate RD patients from healthy individuals.

Main Methods:

  • Utilized a computerized digital thermometer with AVTR interface and probes for all 10 fingers.

  • Measured basal finger temperature, temperature during cooling to 10°C, and recovery response.
  • Examined 51 subjects: 19 asymptomatic and 32 symptomatic for acrolocalized pathologies.

    • Main Results:

    • No strong correlation was found between clinical symptoms and instrumental thermometry data.
    • 31.5% of asymptomatic subjects exhibited "non-normal" thermometry test reactions.
    • 44.4% of symptomatic female subjects over 50 showed normal instrumental patterns, suggesting low specificity.

    Conclusions:

    • Digital thermometry demonstrated good sensitivity but poor specificity for identifying Raynaud's disease.
    • Instrumental parameters failed to reliably distinguish between individuals with and without RD.
    • Further research is needed to refine objective diagnostic tools for Raynaud's disease.
