the definition of the disease or the methodology for detecting clinical parameters&#46; The varying sensitivity and specificity of the methods for detecting ACPA may also affect their value when assessing the association with ILD&#46; The significantly higher positivity in the patients with RA and ILD could indicate that the presence of ACPA could be a good biomarker for diagnosing ILD in patients with RA&#46; It is believed that lung injury from smoking and other stimuli could contribute to protein citrullination modification&#44; which later creates new epitopes and subsequent autoimmune responses&#46;<a class="elsevierStyleCrossRef" href="#bib0245"><span class="elsevierStyleSup">20</span></a> In this regard&#44; a previous history of smoking &#40;for at least 6 months&#41;

the patients with RA and ILD took more sDMARDs than those without ILD&#44; mainly at the expense of MTX&#59; this could be due to the contradictory data described with this DMARD&#58; a meta-analysis of randomised controlled trials describing an increased risk of pneumonitis associated with MTX &#40;RR&#58;

among other reasons because of the non-specific definition of the term pneumonitis&#46;<a class="elsevierStyleCrossRef" href="#bib0275"><span class="elsevierStyleSup">26</span></a> They described the course of lung function in a cohort of patients with RA and ILD and observed improved lung function tests after treatment with corticosteroids plus DMARDs &#40;MTX&#44;

The few studies carried out describe abatacept and rituximab as drugs that could be effective and safe in the treatment of RA with IDL&#44; both at joint level and in stabilisation&#44; even with improvement in respiratory parameters&#46;<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">28&#44;29</span></a> In line with the data described&#44; the distribution of the use of biological therapy in our patients was consistent&#58; higher use of rituximab and abatacept in patients with ILD versus anti-TNF and tocilizumab in the group without ILD&#46; The fact that both patient groups are under treatment could explain why there was no difference in inflammatory activity measured by DAS28 and APR &#40;CRP and ESR&#41; in both groups of patients&#46; The study by Restrepo et al&#46;&#44;<a class="elsevierStyleCrossRef" href="#bib0195"><span class="elsevierStyleSup">10</span></a> like ours&#44; also presents a lower percentage of patients treated with MTX due to contradictory data regarding its pulmonary toxicity&#46; However&#44; they associate this under-treatment with a higher DAS28 in these patients&#46; This might be due to the fact that the patients with ILD in their study were older and had a longer disease duration than those without ILD&#44; which was not the case in our study&#44; because we matched them by sex&#44; age and time since onset&#46;</p><p id="par0120" class="elsevierStylePara elsevierViewall">Among this study&#39;s limitations&#44; since it was performed in routine clinical practice&#44; were that no PFT or HRCT were performed in the group of RA patients without a diagnosis of ILD because they had no associated symptoms and unaltered chest X-rays&#46; Although according to various studies<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">17</span></a> there could already be alterations in PFT and on HRCT in the preclinical phase&#44; in these routine practice patients these tests were requested due to suspected pulmonary involvement&#46; This study is an observational analysis of a cohort of patients with RA and ILD&#44; in whom we prospectively analyse the parameters of respiratory function over time&#44; and a cohort of patients with RA without clinical respiratory symptoms&#46; The study was conducted under routine clinical practice conditions and its results could be extrapolated to situations in this field&#44; although longitudinal studies with a larger number of patients would be necessary to confirm the findings of our study and to establish causality&#46;</p><p id="par0125" class="elsevierStylePara elsevierViewall">To conclude&#44; the results of our study support the higher frequency of the NIU and NINE histopathological patterns in patients with RA and ILD&#44; as well as impaired DLCO as the most important parameter&#46; Patients with RA and ILD are associated with more severe disease &#40;erosions and presence of ACPA&#41; as well as the smoking exposure factor&#46; Treatment with DMARDs in both patient groups controls inflammatory activity&#44; with increased use of the synthetic DMARDS HQC and leflunomide&#44; and the bDMARDs rituximab and abatacept&#44; in patients with ILD&#46; We need to wait for the prospective assessment of these patients to see any association of the treatment with the course of the lung disease&#46;</p></span><span id="sec0090" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0150">Funding</span><p id="par0130" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleGrantSponsor" id="gs1">Andalusian Public Foundation for Health and Biomedicine Research in M&#225;laga &#40;FIMABIS&#41;</span>&#46;
