ACCEPTED MANUSCRIPT Cutaneous Vasculitis

Presentation A 20 year old gentleman presented in September 2014 with an erythematous maculo-papular rash distributed over his lower limbs, trunk & upper limbs. He had

been on adalimumab (Humira, Abbvie, USA), 40 mg fortnightly for dual indication of Crohn's disease and Juvenile Idiopathic arthritis (JIA) since September 2010. He had been in remission from both conditions for over three years.

His blood tests showed raised inflammatory markers but no other abnormality, and a

vasculitis screen was negative.

Progress

He had dramatic worsening of rash over a week in hospital with rapid development of new lesions & bullous transformation of some of the existing lesions with necrotic areas.

A skin biopsy confirmed severe cutaneous leucocytoclastic vasculitis. He was treated with high-dose IV methylprednisolone 1 gram once/day for 5 days followed by oral prednisolone 60mg once/day which was tapered over the next 10 weeks. He

improved with this regimen. There was no specific trigger identified for sudden eruption of lesions. There was consensus among all teams managing him that the most likely cause of cutaneous vasculitis was anti-TNF therapy. We considered checking adalimumab levels but there were no studies demonstrating correlation between anti-TNF drug levels and cutaneous reactions, and the test was

not available locally.

Cutaneous vasculitis is thought to be a very rare adverse effect to adalimumab. There have been very few case reports of cutaneous vasculitis secondary to antiTNF therapy with an average duration of 36 months on treatment prior to developing a reaction, with all responding to drug withdrawal. 1, 3 We believe, to the best of our knowledge that this is the first reported case of bullous vasculitis of this degree of severity, secondary to adalimumab. (Pictures 1-5) The current literature about vasculitis secondary to anti-TNF therapy is scarce. One study reported that when patients who had confirmed cutaneous vasculitis were re-challenged with the same anti-TNF drug, the relapse rate was as high as 67 %.1, 4 The relapse rate was 33% in another study with an alternative anti TNF.1, 5 Therefore

Cutaneous Vasculitis

ACCEPTED MANUSCRIPT we do not plan to use an anti-TNF agent again in our patient. The alternatives approved in the UK for use in adults with JIA but not for Crohn’s disease are Abatacept (IL-1inhibitor) and Rituximab (B-cell monoclonal antibody). The patient has

RI PT

not had a relapse of symptoms related to Crohn’s disease or JIA.

Conclusion

As the use of anti-TNF drugs increases worldwide, it is worth considering them as a possible cause of cutaneous vasculitic lesions. Our experience suggests that

SC

withdrawal of drug and high-dose corticosteroids is an effective treatment strategy. .
