Colchicine, a potential first-line treatment for cutaneous polyarteritis nodosa: Study
Paris: Colchicine is a reasonable first-line treatment for cutaneous polyarteritis nodosa (cPAN) without peripheral sensory neuropathy and has a favorable risk-to-benefit ratio, a recent study has found.
The study, published in the Journal of the American Academy of Dermatology, suggests the use of glucocorticoids (GCs) + azathioprine for patients with sensory neuropathy.
Cutaneous polyarteritis nodosa (cPAN) is a form of medium-sized vessel vasculitis. Despite it being a disabling and prolonged course, there is a lack of data on treatment efficacy and safety. To fill this knowledge gap, Alexis Régent, Université de Paris, Paris, and colleagues aimed to describe treatment efficacy and safety in patients with cPAN.
For this purpose, the researchers conducted a multicentre retrospective observational study. They recorded clinical and biological data together with treatments received. The primary outcome was the rate of complete response (CR) at month 3. Secondary outcomes included drug survival, and safety was assessed.
A total of 68 patients who received a median of 2 therapeutic lines (interquartile range 1-3) were included.
