Abstract: We present an 18-year-old female from South Sudan presented with right fingertips ulceration and black discolouration associated with bilateral wrist/metacarpophalangeal joints pain for five months. The ulceration began at the tip of the right middle finger and gradually progressed to involve the rest of the hand and was associated with agonizing pain. A Doppler study of the right upper limb revealed thrombosis of the antecubital portion of the basilar, ulnar, and part of the distal radial arteries. Blood investigations showed high anti-CCP, doubtful rheumatoid factor titre and ANA titre of 1:320 with coarse and nucleated cells; however, all ANA parameters were negative. A definitive diagnosis of rheumatoid arthritis complicated by rheumatoid vasculitis was made. Unfortunately, the middle finger could not be preserved and ended up amputated, and the patient was commenced on steroids, DMARDs and warfarin. The patient responded very well to the management plan with pain alleviation, ulcers healing and clot resolution.

Introduction
Rheumatoid Vasculitis (RV) is a rare, catastrophic complication of longstanding deforming Rheumatoid Arthritis (RA).1 It is an autoimmune vasculitis characterized by a necrotizing or leukocytoclastic process that mainly affects small to medium-sized blood vessels and is associated with significant mortality rates, making it one of the most serious extra-articular manifestations of rheumatoid arthritis, necessitating prompt recognition and intervention.1,2
Rheumatoid Vasculitis preceding or following a recent diagnosis of rheumatoid arthritis rather than a longstanding disease is a distinct uncommon entity; however, if diagnosed and treated promptly, it can prevent the development of severe comorbidities.3 RA diagnosis is made using EULAR criteria, with the presence of all the following: Inflammatory arthritis involving three or more joints, positive rheumatoid factor (RF) and/or anti-citrullinated peptide antibodies (anti-CCP), elevated levels of CRP and/or ESR and duration of symptoms is more than six weeks.4 Although no current criterion is available to diagnose RV, it should be expected in patients with longstanding rheumatoid arthritis and raised anti-CCP/RF presenting with vasculitis lesions (commonly Digital Ischemia), imaging studies showing ischemia and/or tissue biopsy showing vasculitis, and exclusion of other causes of vasculitis (ANCA related vasculitides, polyarteritis nodosa, etc.).5
The incidence of RV has reduced to a less than 1% among RA patients, given the introduction of methotrexate and other biologic disease-modifying antirheumatic drugs in the recent era.6,7 Nevertheless, autopsy results show a significantly higher percentage of prevalence reaching 30%.8 Males are 2.3 times more prone to developing RV than females.9 Furthermore, the 5-year mortality of RV reaches to almost 40%.10
We present a rare case of RV demonstrated in a non-deforming RA female patient, causing upper limb arterial thrombosis, and warranting middle finger amputation.
Case Report
An 18 years old female nonsmoker from South Sudan presented to the medical casualty with unilateral painful fingertip ulceration and black discolouration for five months. The ulceration began at the tip of the right middle finger and gradually progressed to involve the rest of the hand and was associated with agonizing pain; nevertheless, no involvement of the other hand (no ulcers, discolouration or deformity). The patient sought advice, and a Doppler U/S of the right upper limb revealed arterial thrombosis of the antecubital portion of basilar, ulnar, and part of the distal radial arteries with normal proximal basilar, axillary and subclavian artery. The patient underwent a partial amputation of the right middle finger and was referred for our consultation afterwards as no final diagnosis was reached and no thorough workup was done at the time. On assessing the patient, she reported a seven-month history of high-grade remittent fevers associated with weight loss and fatigue. She also described bilateral wrists and metacarpophalangeal joints pain, not associated with morning stiffness, sicca symptoms (dry skin, dry eyes, etc.), or genital ulceration. A further systematic review was unremarkable, apart from bilateral frontal headache and amenorrhea for five months.
On physical examination, the patient was in pain, not pale or jaundiced, with a weak radial pulse bilaterally, an amputated middle finger and extensive digital ulceration. No ulcers were present elsewhere, and the rest of the examination did not show signs of any inflammatory process, skin lesions or joint deformities (Figure 1).

Routine lab tests, hands X-ray and an immunological workup were requested, revealing normocytic normochromic anaemia, elevated Anti-CCP levels with rheumatoid factor level was doubtful. Nonetheless, the ANA Global titre was 1:320 with coarse and nucleated cells with all ANA parameters being negative, thus suggestive of exclusively active rheumatoid arthritis (Tables 1 and 2).

Hand x-ray shows reduced bone density at the distal end of the radius and ulna, carpal bone, and metacarpophalangeal joint with a fracture in the index and ring fingers and an amputated middle finger (Figure 2).
A definitive diagnosis of rheumatoid arthritis (EULAR 7 and DAS 28-ESR 5.8) complicated with rheumatoid vasculitis was made. The patient was commenced on low-dose prednisolone, hydroxychloroquine, methotrexate, and warfarin. The patient responded very well to the management plan with pain alleviation, ulcers healing, clot resolution and normalization of his inflammatory markers. All medications were continued except for warfarin, which was stopped after six months.
Discussion
Rheumatic vasculitis is an infrequent complication of longstanding severe rheumatoid arthritis. It is one of the most alarming extra-articular manifestations of rheumatoid arthritis and is associated with high morbidity and mortality; however, it manifests in only 1–5% of the patients.11 Deposition of the immune complexes may be a major contributor to vascular inflammation in patients with rheumatoid arthritis. The most common manifestation of rheumatoid vasculitis is cutaneous vasculitis like palpable purpura, nail bed infarcts and digital gangrene,3 which was the presenting complaint in our patient with elevated ESR; consistent with the fact that vasculitis is associated with systemic inflammatory response and the majority of the patients with rheumatoid vasculitis present with very high ESR.2 Furthermore, higher levels of anti-CCP appear to be associated with progressive and severe extra-articular manifestation like vasculitis,3 being 137 in our patient.
The literature reports that vasculitis mainly occurs in patients with a longstanding disease with severe joint deformity.11 Major risk factors for developing vasculitis include male gender, smoking and longstanding disease.3
Our patient, an 18-year-old female nonsmoker, presented with vasculitis that predates the diagnosis of rheumatoid arthritis, which is a very rare and unique presentation.
To the best of our knowledge, only four patients presented with vasculitis preceding or following a recent diagnosis of rheumatoid arthritis. These cases included 61 years male presenting with pulmonary vasculitis with subsequent development of anti-CCP positive symmetric polyarthritis;12 secondly, a 63-year-old man who developed bilateral carpal tunnel syndrome, mononeuritis of both sciatic nerve and inflammatory myositis six months after being diagnosed with rheumatoid arthritis.13 The third was a 38-year-old man presenting with polyarteritis nodosa-like symptoms; however, on stopping treatment after six years, he developed RA; thus, misdiagnosed as at the beginning as PAN rather than rheumatoid vasculitis.14 Lastly, a 74-year-old man presented with acute cholecystitis within a week of diagnosis with rheumatoid arthritis and, nonetheless, histopathologic evidence of small vessel vasculitis and rheumatoid nodules.15
Rheumatoid vasculitis is actively managed with corticosteroids and cyclophosphamide.11 Furthermore, cutaneous vasculitis commonly responds to lower doses of immunosuppression than systemic vasculitis, which mandates higher doses of immunosuppression and has an overall poor prognosis.14
Conclusion
Rheumatoid vasculitis preceding non-deforming RA is a very rare entity causing devastating outcomes. Prompt recognition and management are crucial given their wide range of involvements and complications. Therefore, a multidisciplinary approach is required, together with further studies to be performed to construct an explicit criterion for diagnosis and management.
