Advances, limitations and future perspectives in the diagnosis and management of dry eye in Sjogren's syndrome
Primary Sjogren's syndrome is a complex systemic autoimmune disorder that primarily affects exocrine glands such as the lacrimal glands. Dry eye disease is one of the most prevalent complications of Sjogren's syndrome, affecting most patients. It significantly impairs quality of life and management is often difficult and unsatisfactory, in part due to weak correlation between symptoms and signs and poor recognition of the three main subtypes aqueous-deficient, evaporative and neuropathic dry eye. This review provides an overview of key aspects of dry eye disease, such as its multifactorial aetiology and recent insights into pathophysiology. The uses and pitfalls of commonly-used diagnostic tests for dry eye are reviewed, as well as the increasing number of new imaging technologies and biomarkers to refine diagnosis. There are many current and emerging treatment options for dry eye in Sjogren's syndrome, but high-level evidence of efficacy is mostly lacking, as are evidence-based treatment algorithms. All these aspects make the management of dry eye in Sjogren's syndrome challenging

Assessing recovery after cold challenge and thumb involvement can help to rule out systemic sclerosis in patients presenting with Raynaud?s phenomenon
Objective: Our aim was to study whether recovery from a Raynaud?s attack and involvement of the thumb are differentiators for systemic sclerosis (SSc) in patients with Raynaud?s phenomenon (RP). Method: A stepwise cooling and recovery procedure was performed, provoking an RP attack, in patients with primary Raynaud?s phenomenon (PRP, n =?68) and SSc (n?=?18). During the procedure, the perfusion of all five fingers during cooling and recovery was assessed by photoelectric plethysmography. Results: In SSc patients, perfusion after 10?min in one or more fingers was more frequently not restored than in PRP patients (p?=?0.001), with a negative predictive value of 98%. The thumb was more frequently involved in SSc patients (p?=?0.036), with a negative predictive value of 95%. Positive predictive values were low. Conclusions: In patients with RP, when there is restoration of perfusion in all fingers after 10?min or when the thumb is spared, the presence of an underlying SSc is very unlikely. Although these results need to be validated in a clinical setting in a larger prospective study, these signs can help physicians to select additional testing for SSc in RP patients
Development and performance of the Clinical Trials ESSDAI (ClinTrialsESSDAI), consisting of frequently active clinical domains, in two randomised controlled trials in primary Sjogren's syndrome
Objective. To develop and evaluate the Clinical Trials EULAR Sjogren's Syndrome Disease Activity Index (ClinTrialsESSDAI), consisting of frequently active clinical domains of the ESSDAI, using two randomised controlled trials in primary Sjogren's syndrome (pSS). Methods. The ASAP-III trial in abatacept (80 pSS patients) and TRACTISS trial in rituximab (133 pSS patients) were analysed. The most frequently active clinical domains were selected, and ClinTrialsESSDAI total score was calculated using existing weightings of the ClinESSDAI (which also excludes the biological domain). Performance of the ClinTrialsESSDAI was compared to ClinESSDAI and ESSDAI. Responsiveness was assessed using standardised response mean (SRM), and discrimination was assessed using adjusted mean difference. Results. Besides the biological domain, the most frequently active domains were glandular, articular, haematological, constitutional, lymphadenopathy and cutaneous. These domains were selected for the ClinTrialsESSDAI. At primary endpoint visits, SRM values of ClinTrialsESSDAI, ClinESSDAI and ESSDAI were respectively -0.65/-0.59, -0.63/-0.59 and - 0.64/-0.61 for abatacept/placebo and -0.33/-0.13, -0.34/0.12 and -0.41/-0.16 for rituximab/placebo. Adjusted mean differences between active treatment and placebo groups were respectively -1.7, -1.4 and -1.1 for ASAP-III and -1.1, -1.1 and -1.2 for TRACTISS. Conclusion. The ClinTrialsESSDAI, consisting of six frequently active clinical domains of the ESSDAI, shows closely similar responsiveness and discrimination between treatment groups compared to the ClinESSDAI and ESSDAI. Therefore, this ClinTrialsESSDAI is not preferable to ClinESSDAI and ESSDAI for use as primary endpoint. A composite endpoint combining response at multiple clinically relevant items seems more suitable as primary study endpoint in pSS
