Plasma filtration in patients with Raynaud’s phenomenon

Fourteen patients with severe Raynaud’s phenomenon, 7 with primary Raynaud’s phenomenon and 7 with secondary Raynaud’s phenomenon based on progressive systemic sclerosis, were treated with plasma filtration. Haemorheological parameters were determined before and after treatment. Eight patients (6 patients with secondary Raynaud’s phenomenon) responded very well. The frequency of Raynaud’s phenomenon and cold induced attacks were strongly reduced The skin which was tough and tense before filtration became supple and pliable, so that patients could use their extremities more easily. Also their facial expression became livelier. Fingertip ulcerations showed increased healing tendency.

Elevated red blood cell aggregation and plasma viscosity were markedly reduced after plasma filtration.
