Nomenclature for the disease widely known as Sjögren syndrome has proven unsatisfactory. Patients have perceived ‘syndrome’ as indicative of a vague collection of symptoms, prompting the Sjögren’s Foundation to abandon the term. Furthermore, the traditional distinction between ‘primary’ and ‘secondary’ forms fails to account for the complex interplay between overlapping autoimmune diseases. Following a bibliometric analysis, systematic literature review and a Delphi consensus process with equal involvement of professional and patient representatives, five recommendations are now issued. First, the term ‘Sjögren disease’ should replace ‘Sjögren syndrome’. Second, the acronym ‘SjD’ should be used as an abbreviation for ‘Sjögren disease’. Third, the descriptor ‘associated’ should be used in lieu of ‘secondary’ for Sjögren disease occurring in association with a second systemic autoimmune disease for which classification criteria are fulfilled. Fourth, Sjögren disease is the preferred terminology in common parlance and in clinical diagnosis, without differentiation as to primary and associated forms. Fifth, the differentiation between primary and associated Sjögren is recommended for scientific studies to define a homogeneous population. In conclusion, the consensus endorses ‘Sjögren disease’ as the official nomenclature to acknowledge the distinct pathogenesis of this disorder and to improve clarity in both clinical practice and research.

Pulmonary disease is a potentially serious yet underdiagnosed complication of Sjögren's syndrome, the second most common autoimmune rheumatic disease. Approximately 16% of patients with Sjögren's demonstrate pulmonary involvement with higher mortality and lower quality of life. Clinical practice guidelines for pulmonary manifestations of Sjögren's were developed by the Sjögren's Foundation after identifying a critical need for early diagnosis and improved quality and consistency of care. A rigorous and transparent methodology was followed according to American College of Rheumatology guidelines. The Pulmonary Topic Review Group (TRG) developed clinical questions in the PICO (Patient, Intervention, Comparison, Outcome) format and selected literature search parameters. Each article was reviewed by a minimum of two TRG members for eligibility and assessment of quality of evidence and strength of recommendation. Guidelines were then drafted based on available evidence, expert opinion, and clinical importance. Draft recommendations with a clinical rationale and data extraction tables were submitted to a Consensus Expert Panel for consideration and approval, with at least 75% agreement required for individual recommendations to be included in the final version. The literature search revealed 1,192 articles, of which 150 qualified for consideration in guideline development. Of the original 85 PICO questions posed by the TRG, 52 recommendations were generated. These were then reviewed by the Consensus Expert Panel and 52 recommendations were finalized, with a mean agreement of 97.71% (range, 79%-100%). The recommendations span topics of evaluating Sjögren's patients for pulmonary manifestations and assessing, managing, and treating upper and lower airway disease, interstitial lung disease, and lymphoproliferative disease. Clinical practice guidelines for pulmonary manifestations in Sjögren's will improve early identification, evaluation, and uniformity of care by primary care physicians, rheumatologists, and pulmonologists. Additionally, opportunities for future research are identified.

Primary Sjögren's disease (pSjD) is an autoimmune rheumatic disease involving exocrine glands and associated with high symptom burden (dryness, fatigue, pain), systemic features and salivary gland dysfunction. B-cell hyperactivity is common, with an increased risk of mucosa-associated lymphoid tissue lymphoma. This review describes the unmet need, scientific validity of outcome measures, optimisation of clinical trial design, therapeutic advances and how clinical improvement relates to health-related quality of life, additional quality-adjusted life years and economic benefit in pSjD. It derives from the EU-funded Necessity IHI Academic-Industry collaborative Consortium project while also drawing on work by the European Alliance of Associations for Rheumatology Sjögren's task force and others. The NECESSITY Consortium, formed within the framework of the Innovative Health Initiative (IHI), comprises 20 academic partners, 1 patient group partner and 4 industry partners (NECESSITY; https://necessity-h2020.eu). Patient leaders have been closely involved, with expert advice obtained from the European Medicines Agency and the United States Food and Drug Administration during the development phase of a new outcome measure, the Sjögren's Tool for Assessing Response composite response criteria. This tool is now undergoing validation through the NECESSITY IHI clinical trial and industry-sponsored trials.

Context The severity of Sjögren’s syndrome has been evaluated using a wide variety of clinical measures and patient-reported outcomes (PROs). This may contribute to the lack of clarity concerning the burden of Sjögren’s from the patient perspective. Objective To perform a comprehensive peer-reviewed literature analysis of the patient aspects of Sjögren’s, focusing on PROs, to investigate the complexity underlying the evaluation of the syndrome and to elucidate the discordance between the different measures. Methods We searched Embase for articles published between January 2005 and September 2015. Research articles, clinical and diagnostic reviews, and validation studies with a focus on patient aspects of Sjögren’s were selected as the primary information source. Results 157 articles met the eligibility criteria. A wide variety of assessment measures used to evaluate glandular, extraglandular and functional domains were observed. Many different, non-validated Visual Analogue Scales, with a wide range of anchor words, were used in the quantification of Sjögren’s disease burden, impeding comparisons between studies. Relatively few clinical trials of drug therapies used validated scales: European League Against Rheumatism Sjögren’s Syndrome Patient Reported Index was used most often for symptom assessment and 36 Item Short Form Survey for quality of life (QoL). Conclusion A wide range and diversity of measures are used to evaluate the patient burden of Sjögren’s; most are not validated for use in this disease. PRO endpoints, validated specifically in Sjögren’s, that demonstrate improvement are needed. These measures should focus on QoL aspects important to patients and will most likely involve gauging change in function rather than patient-reported symptoms.
