    Journal: J Rheumatol; 2002 Jul; 29(7):1401-3. PubMed ID: 12136896.
    Abstract:
    OBJECTIVE: Establishing a cold stimulus test based on the measurement of finger tip lacticemy (FTL) in Raynaud's phenomenon (RP). METHODS: Twenty-seven controls and 79 patients with RP [30 systemic sclerosis (SSc) and 49 isolated RP] were studied. The latter were further classified into probable primary RP (PPRP) and probable secondary RP (PSRP). FTL was determined before (pre-CS) and after (post-CS) a cold stimulus and the percentage difference was designated ACS-FTL. RESULTS: Pre-CS-FTL was marginally higher in SSc patients than in isolated RP and controls. Post-CS-FFL was significantly higher in SSc and PSRP than in PPRP and controls. SSc and PSRP patients had higher post-CS-FTL than pre-CS-FTL (positive ACS-FTL) while controls presented a negative ACS-FTL. Post-CS-FTL had a heterogeneous behavior in patients with PPRP. CONCLUSION: CS-FTL test was shown to be an easy method for evaluation of fingertip effective perfusion before and after a cold stimulus. Further studies are warranted to test its possible clinical application in discriminating between patients with SSc and controls, as well as between patients with PPRP and PSRP.
