[Keratoconus in a young patient with itching eyes and blurred vision]. / Denk aan keratoconus bij oogwrijven en waziger zicht.

Keratoconus is an asymmetric bilateral eye condition that results in an increase in corneal curvature and a decrease of corneal thickness. Increasing myopia and astigmatism result in a decrease of visual acuity. The condition frequently begins in the second decade, gets worse during the next few years, and stabilizes about age 35. Risk factors include eye rubbing, and familial predisposition. Contact lenses or corneal transplants are two possible treatments. Nowadays, the illness can be stopped through corneal cross-linking.

Patient Acceptable Symptom State (PASS) in patients with primary Sjögren's syndrome in daily clinical practice.

OBJECTIVES: To explore Patient Acceptable Symptom State (PASS) in a standard of care cohort of patients with primary Sjögren's syndrome (pSS) and to compare patient characteristics including EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) between PASS and non-PASS groups. METHODS: All pSS patients fulfilling ACR/EULAR classification criteria from the Registry of Sjögren's Syndrome LongiTudinal (RESULT) cohort, who had available PASS data at baseline were included. Patient-reported outcomes included the PASS question: "Considering all the different ways your disease is affecting you, if you were to stay in this state for the next few months, do you consider your current state satisfactory?"; yes: PASS / no: non-PASS. RESULTS: Of the 278 included pSS patients, 199 (72%) had an acceptable symptom state according to the PASS question, and median ESSPRI was 6 (IQR 4-7). In the PASS group, 118 (59%) patients had an unacceptable symptom state according to ESSPRI (score ≥5). In multivariable regression analyses, ESSPRI and disease duration were independently associated with presence of PASS. The accuracy of ESSPRI to predict PASS was fair (AUC of 0.78). The cut-off point of ESSPRI for presence of PASS with the highest Youden's index was 7.2 (sensitivity 85%, specificity 56%), followed by 5.2 (sensitivity 48%, specificity 90%). CONCLUSIONS: The majority of pSS patients reported being in an acceptable symptom state according to the PASS question, despite high ESSPRI scores. In our standard of care cohort, the optimal cut-off point of ESSPRI to predict PASS is different when focusing on sensitivity (±7) or specificity (±5).

Long-term abatacept treatment for 48 weeks in patients with primary Sjögren's syndrome: The open-label extension phase of the ASAP-III trial.

OBJECTIVE: To investigate treatment efficacy of long-term abatacept treatment in pSS patients. METHODS: The single-centre ASAP-III trial consisted of two phases: the randomised, double-blind, placebo-controlled phase (1:1 randomisation) from baseline to week 24, of which results have been published previously, and the open-label extension phase from week 24 to 48, in which all patients received abatacept. Main inclusion criteria were fulfilment of the AECG criteria, positive gland biopsy, disease duration ≤ 7 years and ESSDAI ≥ 5. Long-term treatment effects of abatacept on clinical, patient-reported, glandular and laboratory outcome measures were assessed in patients treated with abatacept from baseline to week 48. Furthermore, Composite of Relevant Endpoints for Sjögren's Syndrome (CRESS) response (response on ≥3 of 5 items) was analysed. RESULTS: In patients on abatacept treatment for 48 weeks (n = 40), median ESSDAI improved from baseline 14.0 (IQR 9.0-16.8) to 4.0 (2.0-8.0) at week 48 (p < 0.001), with 50% of patients reaching low disease activity (ESSDAI < 5) at week 48. Median ESSPRI improved from 7.0 (IQR 5.4-7.7) to 5.0 (3.7-6.7) (p < 0.001). Significant improvement was also seen in dry eye and laboratory tests. Combining response at multiple clinically relevant items, 73% of patients were CRESS responders at week 48. Additional improvement was seen between week 24 and week 48 of abatacept treatment. CONCLUSION: In the open-label extension phase of the ASAP-III trial, improvement was seen up to 48 weeks of abatacept treatment in clinical, patient-reported, dry eye and laboratory outcomes. The majority of patients were CRESS responders at week 48.

Clinical Phenotyping of Primary Sjögren Syndrome Patients Using Salivary Gland Ultrasonography: Data From the RESULT Cohort.

OBJECTIVE: To investigate salivary gland ultrasound (SGUS) abnormalities in relation to clinical phenotype and patient characteristics, disease activity, and disease damage in patients with primary Sjögren syndrome (pSS). METHODS: Consecutive outpatients included in our REgistry of Sjögren Syndrome LongiTudinal (RESULT) cohort were selected. Patients with pSS who were included were classified according to the American College of Rheumatology/European League Against Rheumatism (EULAR) criteria and underwent full ultrasonographic examination (Hocevar score 0-48) at baseline. Total SGUS scores of ≥ 15 were considered positive. Patient characteristics, disease activity, and disease damage were compared between the different SGUS groups. RESULTS: In total, 172 of 186 patients with pSS were eligible, of whom 136 (79%) were SGUS positive. Compared with patients who were SGUS negative, SGUS-positive patients had significantly longer disease duration, higher EULAR Sjögren Syndrome Disease Activity Index, higher Sjögren Syndrome Disease Damage Index, and were more likely to have a positive parotid gland biopsy, anti-SSA/SSB antibodies, and abnormal unstimulated whole saliva (UWS) and ocular staining score (OSS), and higher levels of IgG and rheumatoid factor. Regarding patient-reported outcome measurements (PROM), patients who were SGUS positive scored significantly lower on the EULAR Sjögren Syndrome Patient-Reported Index for fatigue and pain, and more often found their disease state acceptable compared with patients who were SGUS negative. SGUS total score showed significant associations with various clinical and serological variables, and with PROM. Highest associations were found for UWS (ρ = -0.551) and OSS (ρ = 0.532). CONCLUSION: Patients who were SGUS positive show a distinct clinical phenotype in all aspects of the disease compared with patients who were SGUS negative: clinical, functional, serological, and PROM. SGUS could be a helpful tool in selecting patients for clinical trials and estimating treatment need.

Abatacept treatment for patients with early active primary Sjögren's syndrome: a single-centre, randomised, double-blind, placebo-controlled, phase 3 trial (ASAP-III study).

BACKGROUND: Several small open-label studies have suggested efficacy of abatacept-a co-stimulation inhibitor-in patients with primary Sjögren's syndrome. These promising results warranted further evaluation. We therefore aimed to further assess the safety and efficacy of abatacept compared with placebo in patients with primary Sjögren's syndrome. METHODS: We did a single-centre, randomised, double-blind, placebo-controlled, phase 3 trial at the University Medical Center Groningen (Groningen, Netherlands). We included patients with primary Sjögren's syndrome fulfilling the American-European Consensus Group criteria, aged 18 years or older, with positive salivary gland biopsies, time from diagnosis of 7 years or less, and a European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI) score of 5 or more. Independent pharmacists randomly allocated patients (1:1) to either the abatacept group or placebo group using a computer-generated sequence stratified by previous use of disease-modifying anti-rheumatic drugs. Patients received at-home subcutaneous injections of abatacept (125 mg) or placebo once a week for 24 weeks. The primary outcome was the between-group difference in ESSDAI score at week 24. Efficacy was analysed in patients who received at least one drug dose and for whom post-baseline data were collected. Safety was analysed in all patients who received at least one drug dose. FINDINGS: Between Aug 14, 2014, and Aug 23, 2018, 580 patients were reviewed for eligibility, of which 80 patients were randomly assigned to receive study treatment. Efficacy was analysed in 40 patients receiving abatacept and 39 patients receiving placebo (one patient in this group was lost to follow-up). The primary outcome did not significantly differ between the treatment groups. The adjusted mean difference in ESSDAI score at week 24 between the abatacept group and placebo group was -1·3 (95% CI -4·1 to 1·6). No deaths or treatment-related serious adverse events occurred. In 38 (95%) of 40 patients in the abatacept group, 103 adverse events occurred, including one serious adverse event and 46 infections. In 38 (95%) of 40 patients in the placebo group, 87 adverse events occurred, including four serious adverse events and 49 infections. INTERPRETATION: On the basis of this trial, we cannot recommend abatacept treatment as standard of care to reduce systemic disease activity in patients with primary Sjögren's syndrome. Further studies should evaluate whether patients with specific clinical manifestations and biological characteristics might benefit from abatacept treatment. FUNDING: Bristol-Myers Squibb.
