PREVIOUS work1 has demonstrated that patients with lupus erythematosus have an altered peripheral circulation, as demonstrated by changes in the form of the photoelectric plethysmogram of the fingers. It is the purpose of this paper to present evidence that the same kind of changes exist in the peripheral circulation of patients with psoriasis. This alteration in the peripheral circulation is similar to that reported in arteriosclerosis,2 hypertension,2 pseudoxanthoma elasticum,3 and scleroderma.4
MATERIAL AND METHODS
Studies were made on 28 normal subjects and on 11 patients with psoriasis. The extent, acuity, or activity of the psoriasis was not recorded except to note that there was no clinical evidence of nail involvement at the time of the studies. Also, none of the patients had clinical or radiological evidence of hypertension or arteriosclerosis.
The photoelectric plethysmograph used in this study was a modification of that described by Hertzman.
