Background: Ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) are chronic conditions with overlapping pathogenic mechanisms. The genetic predisposition and inflammatory pathways common to both diseases suggest a syndemic relationship. While some evidence points to a connection between the two conditions, other reports do not support this link.

Objectives: To investigate the association between AS and the subsequent incidence of IBD. To identify potential risk factors and effect modifiers that contribute to this relationship.

Methods: Utilizing the Chronic Disease Registry of Clalit Health Services, we conducted a retrospective cohort study of individuals diagnosed with AS between January 2002 and December 2018. We compared these patients with age- and sex-matched controls, excluding those with a prior diagnosis of IBD. Statistical analyses included chi-square and t-tests for demographic comparisons, and Cox proportional hazards models for evaluating the risk of IBD development, with adjustments for various co-morbidities and demographic factors.

Results: The study included 5825 AS patients and 28,356 controls. AS patients demonstrated a significantly higher incidence of IBD with hazard ratios of 6.09 for Crohn's disease and 2.31 for ulcerative colitis, after multivariate adjustment. The overall incidence of IBD in the AS cohort was significantly higher compared to controls.

Conclusions: AS patients exhibit a markedly increased risk of developing IBD. These findings advocate for heightened clinical vigilance for IBD symptoms in AS patients and suggest the need for a multidisciplinary approach to patient care. Further research into the shared pathogenic pathways is needed to develop personalized treatment strategies and improve patient management.

Backgrounds: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression.

Objectives: To evaluate the association between BD and depression, adjusting for established risk factors for depression.

Methods: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex.

Results: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37–2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39–2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18–39 years of age), low and high socioeconomical status, and non-smokers.

Conclusions: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Background: Systemic sclerosis (SSc) is a connective tissue disease that may affect the heart and the autonomic nervous system (ANS). There is little knowledge regarding the degree of ANS involvement in SSc patients with unknown cardiac disease.

Objectives: To evaluate cardiac and pupillary autonomic functions in patients before cardiac involvement has emerged.

Methods: The study comprised 19 patients with SSc and 29 healthy controls. Heart rate variability (HRV) analysis for time and frequency domains, as well as deep breathing test and Ewing maneuvers, were performed in all patients. Automated pupillometry for the evaluation of pupillary diameter and pupillary light reflex was completed in 8 SSc patients and 21 controls.

Results: Both groups had similar characteristics, except for medications that were more commonly or solely prescribed for SSc patients. Compared with control subjects, the SSc patients had significantly lower HRV parameters of NN50 (15.8 ± 24.4 vs. 33.9 ± 33.1, P = 0.03), pNN50 (4.9 ± 7.4% vs.10.8 ± 10.8%, P = 0.03), and triangular index (11.7 ± 3.4 vs. 15.7 ± 5.8, P = 0.02). Abnormal adaptive responses in heart rate changes were recorded during deep breathing tests and Ewing maneuvers. There was no significant difference in any of the pupillometric indices or other HRV parameters within groups.

Conclusions: SSc patients may manifest cardiac autonomic dysfunction, while their autonomic pupillary function is seemingly spared. The role of certain medications, the significance of differential organ involvement, as well as the prognostic value of our findings should be evaluated in future studies

Background: Granulomatosis with polyangiitis (GPA) is a rare small vessel vasculitis. It usually involves the respiratory tract and kidney. Rarely, tumor-resembling inflammatory changes ensue.

Objectives: To report three unique cases of GPA presenting with tumor-like lesions in various organs.

Methods: We presented three cases of GPA. Case 1 presented with typical upper respiratory symptoms of GPA and a mediastinal mass. Case 2 presented with low back pain, a large retroperitoneal mass, and nodular skin lesions. Case 3 presented with epigastric pain and a paravertebral inflammatory mass.

Results: The patients were treated successfully with rituximab.

Conclusions: Clinicians should be aware of this presentation of granulomatosis with polyangiitis, which is known as Tumefaction Wegener’s granulomatosis
