Observational study on patients suffering of Raynaud's phenomenon

ABSTRACT

We examined Raynaud's phenomenon in systemic sclerosis [SSc], systemic lupus erythematosus [SLE] and rheumatoid arthritis [RA] to determine its relation to the clinical and laboratory data of different rheumatic diseases. Thirty-six patients were included in our study 18 of them with and 18 without Raynaud's phenomenon. There was a significant difference between both groups as regards clinical data of cerebritis, nephritis and systolic blood pressure where such were higher in the Raynaud's positive group than Raynaud's negative group. These findings can be explained on the patho-physiological basis of the disease itself. We can get either affection of the kidney [nephritis] or vasculitis presenting by cerebritis or due to the circulating endothelin substance
