Background Nailfold videocapillaroscopy (NVC) visualizing microvascular damage is an important tool to differentiate Raynaud's phenomenon (RP) into primary RP (PRP) and secondary RP (SRP) (1). Based on possible transition from PRP to SRP (semi)annual NVC has been advocated to detect transition to SRP as early as possible (1-3). Whether standardized (semi)annual NVC should be implemented in clinical practice is unknown.

Objectives To evaluate the additive diagnostic value of repeated NVC after one year in patients with RP.

Methods Patients with RP who underwent NVC at the outpatient clinic at least six months ago and did not have a definite diagnosis were invited for follow-up NVC. PRP was defined according to the definition of LeRoy (4); SRP was defined as RP associated with a connective tissue disease fulfilling applicable diagnostic criteria; the remaining patients were classified as suspected SRP (sSRP). The number of patients in which follow-up NVC resulted in change of diagnosis was determined.

Results In total 107 patients with RP underwent NVC. Of these71 underwent follow-up NVC after a mean period of 12 months (range 6-25 months). At baseline, eight (11%) patients had PRP, 28 (40%) SRP and 35 (49%) sSRP. The rate of progression from PRP to SRP was 12.5% (one of eight patients). The rate of progression from sSRP to SRP was 3% (one of 35 patients). NVC pattern had changed in 21 (30%) patients: six (8%) worsened and 15 (21%) improved. In total five patients (7%) had a different diagnosis at follow-up, two of which based on clinical symptoms, three based on NVC pattern only: one changed from PRP to SRP, based on development of sclerodactyly, one changed from sSRP to SRP based on biopsy proven myositis, and three patients changed from sSRP to PRP due to normalization of NVC. Thus, NVC contributed to change in diagnosis in three out of 43 patients (7%) with PRP or sSRP, all improving from sSRP to PRP.

Conclusions Although progression from PRP to SRP was observed in 12.5% and progression from sSRP to SRP in 3%, changes in NVC did not contribute to change in clinical diagnosis in these patients. Based on the findings of this study, a follow-up NVC after one year in patients with PRP or sSRP without a change in clinical symptoms cannot be advocated. Extended follow-up in a larger population is needed to confirm this observation.
