Microvascular Changes in Patients with Psoriatic Arthritis as Shown in Nail Fold Capillaroscopy

Alireza Rajaei, Pooneh Dehghan


P-value less than 0.05 was considered statistically significant.Participants had a mean age of 44.2512.20; 34 patients (62.9%) were female and 20 (37.03%) were male. Tortuosity of capillaries was observed in 54 cases and angiogenesis in 40 patients. Early scleroderma pattern was observed in 15 cases (27.77 %) and 39 patients fell into the normal category(72.22%). The morphological abnormalities, except angiogenesis and avascular area, was significantly more frequent in patients with scleroderma pattern, compared with patients with normal pattern (P<0.05).

As a conclusion we can say that Nail fold capillaroscopy, considered by many expert the gold standard method of microvascular investigation play an important role in evaluation and follow up of patients with psoriasis and the results potentially affect prognosis.

Microvascular changes play an important role in the pathogenesis of many manifestations and complications of psoriatic arthropathy. Early diagnosis play an important role in the management of the disorder and probable long term complications. Nail fold Video Capillaroscopy (NVC) is an effective, non-invasive, easily accessible and cheap method of microvascular investigation. The aim of this study was to evaluate nail fold capillaroscopic findings in patients with psoriatic arthritis. This cross-sectional study was conducted in Ressalat Hospital Nail Fold Capillaroscopic Center and capillaroscopic findings of 54 patients referred to the center between 2011 and 2014were reviewed. Nail fold capillaroscopy was performed on all fingers (10 fingers for each patient). Microvascular architecture; capillary distribution, morphology and density; efferent/afferent limb ratio, sub-papillary venular plexus and morphological abnormalities were recorded and reviewed. Results were reported as scleroderma pattern, nonspecific morphological abnormalities and normal. Results were analyzed qualitatively and quantitatively using SPSS 21 software. "Chi square" test was used to analyze the relationships between variables.
