Raynaud's syndrome: comparison of late and early onset forms using hand perfusion scintigraphy.
Primary Raynaud's disease is generally a disease of younger females; however, there are cases where symptoms present over the age of 40. These cases are described as late onset. In our current prospective study we compared the characteristics of early and late onset types of primary Raynaud's in 127 patients. In addition to the collection of medical records, we performed capillary-microscopy and hand perfusion scintigraphy using Tc-99 m DTPA to evaluate the microcirculation of each patient's fingers. Regarding the spectrum of the capillary-microscopic findings, we did not find any significant difference between the early and late onset forms. However, in hand perfusion examinations done using Tc-99 m DTPA, we measured a significantly lower finger/palm ratio (FPR) in the early onset group of patients. We also observed a correlation between the duration of the disease and the FPR, as well as between the age and FPR. Longer disease duration resulted in a significantly lower FPR. On the basis of our results, we believe that late onset Raynaud's should be treated as a separate entity. Due to its different characteristics found on examination and follow-up of our patients, functional hand perfusion examination should be recommended independently of the age-related characteristics of the disease.
