The patient showed marked improvement on the combination DMARDs and during the course of his disease he remained in remission without active synovitis or morning stiffness. He did well until January 2017 when he developed rapidly progressive shortness of breath with irrigative dry cough.

After 1 week, the chest symptoms worsened and the patient was admitted to the intensive care unit with severe respiratory distress. Oxygen saturation was 78% on room air and follow-up high-resolution CT (HRCT) of the lungs showed extensive areas of ground glass veiling and opacification together with interstitial subpleural infiltrates (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). The patient was transferred to the ICU with acute respiratory failure due to exacerbation of interstitial autoimmune pneumonitis and urgent mechanical ventilation was carried out together with IV pulse steroids, IV antibiotics, and other supportive measures.

Anti-CCP-positive ASS patients showed an overlapping RA-ASS syndrome were at high risk of refractory erosive arthritis and might experience ASS flare when treated with antitumor necrosis factor drugs. In contrast, other biologics such as anti-CD20 mAb were effective in this context, without worsening systemic involvements notably ILD.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">8</span></a> Our patient had muscle pains but normal CK levels and no evidence of neither mechanic hands nor Raynaud's phenomenon. In a landmark single-center study, polyarthritis was the first manifestation in 12 out of 45 (27%) cases with ASS who presented with polyarthritis. The mean delay from polyarthritis onset to ASS diagnosis was 27 months. Pulmonary and muscle symptoms were uncommon at initial ASS diagnosis (40 and 32.5%, respectively) and occurred with a mean delay after polyarthritis onset of 41 and 21 months, respectively. Mechanic's hands and other cutaneous signs of dermatomyositis (DM) occurred in 25 and 22.5%, respectively, with a mean delay of 10 and 31 months, respectively; Raynaud's phenomenon (RP) in (32%) was the earliest non-articular manifestation with mean delay of 3 months after polyarthritis onset. The authors ended that ASS may be revealed by polyarthritis, and to decrease the delay in diagnosis of ASS, pulmonary and muscle symptoms and anti-ARS antibodies might usefully be searched for in seronegative polyarthritis patients, especially in those with RP.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">13</span></a> Given that these diversities in clinical manifestations of RA-ASS overlap syndrome should be taken into consideration.
