Semin Arthritis Rheum 2022; 55:152026. [PMID: 35623241 DOI: 10.1016/j.semarthrit.2022.152026] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 04/22/2022] [Accepted: 05/10/2022] [Indexed: 01/31/2023]
Abstract
OBJECTIVES Sicca complaints are a frequent reason for rheumatologic consultation. Testing for specific antibodies against Ro/SSA and La/SSB antigens and minor salivary gland (MSG) biopsy are among the main tools implemented in the diagnostic work-up. Anticentromere antibodies and sicca manifestations are frequently detected in Sjögren's syndrome (SS) and systemic sclerosis (SSc), respectively. Herein, we aimed to determine the frequency and clinical associations of a wide spectrum of scleroderma (SSc)-specific autoantibodies in consecutive patients referred for evaluation of possible SS. METHODS Demographic, clinico-pathological, and laboratory data were recorded in 216 consecutive patients with sicca complaints. All study participants were tested for SSc-specific autoantibodies (against CENP, PM/Scl, Scl-70, Ku, NOR90, RP11, RP155, fibrillarin, PDGFR, and Th/To) using a commercially available immunoblot kit. According to band intensity, the identified autoantibodies were further classified in those with strong and medium titers. RESULTS SSc-specific autoantibodies were detected in 41.7% (90/216) patients evaluated (19% at strong, 22.7% at medium titers) without significant differences between anti-Ro/SSA positive and negative groups. At strong titers was significantly higher in patients with MSG biopsies fulfilling SS histopathological criteria (30% vs 12.5%, p = 0.009). This association remained significant after adjustment for antibodies against Ro/SSA and La/SSB autoantigens [OR 95% (CI): 4.1 (1.5-10.6)]. CONCLUSION SSc-specific autoantibodies are frequently detected among patients presenting with sicca complaints and at strong but not medium titers are independently associated with MSG biopsy positivity. Taken together, these data imply a useful role of SSc antibody testing in the diagnostic work-up and possibly in the classification criteria for SS.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic systemic autoimmune rheumatic disease characterized by lymphoplasmacytic infiltration of the salivary and lacrimal glands, whereby sicca syndrome and/or systemic manifestations are the clinical hallmarks, associated with a particular autoantibody profile. pSS is the most frequent connective tissue disease after rheumatoid arthritis, affecting 0.3-3% of the population. Women are more prone to develop pSS than men, with a sex ratio of 9:1. Considered in the past as innocent collateral passive victims of autoimmunity, the epithelial cells of the salivary glands are now known to play an active role in the pathogenesis of the disease. The aetiology of the "autoimmune epithelitis" still remains unknown, but certainly involves genetic, environmental and hormonal factors. Later during the disease evolution, the subsequent chronic activation of B cells can lead to the development of systemic manifestations or non-Hodgkin's lymphoma. The aim of the present comprehensive review is to provide the current state of knowledge on pSS. The review addresses the clinical manifestations and complications of the disease, the diagnostic workup, the pathogenic mechanisms and the therapeutic approaches.

Abstract
Sjögren's syndrome (SS) and autoimmune thyroid diseases (AITD) may frequently coexist in clinical practice, resulting in a complex overlapping disorder that represents a particular example of the expression of heterogeneity in patients with autoimmune disorders. Objective of this review was to describe the prevalence of the SS-AITD association in the most recent literature, exploring in particular to what extent the presence of AITD might influence the clinical expression of SS and vice versa. Moreover, we summarized some of the proposed genetic, biologic, and molecular mechanisms implied in the pathogenesis of AITD-SS association. Finally, we explored risk factors for lymphoma development in both AITD and SS. We performed a Medline search of English language articles published in the PubMed database in order to provide a critical overview of the recent literature on pathogenesis and clinical features of AITD-SS overlapping disease. All the articles were critically analyzed to select the most relevant contributions.

High Prevalence of Thyroid Disease and Role of Salivary Gland Scintigraphy in Patients with Xerostomia. Nucl Med Mol Imaging 2017; 51:169-177. [PMID: 28559942 DOI: 10.1007/s13139-016-0455-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 09/27/2016] [Accepted: 09/28/2016] [Indexed: 10/20/2022] Open
Abstract
PURPOSE Although Sjögren's syndrome (SS) is the most common disease causing xerostomia, autoimmune thyroid diseases can also affect the salivary glands. The aim of our study was to estimate the prevalence of thyroid diseases (TD) in subjects with symptoms of xerostomia and evaluate the efficacy of salivary gland scintigraphy (SGS) in the detection of TD in patients with SS and without SS. METHODS We retrospectively reviewed the SGS findings of 173 subjects (men:women, 29:144) with symptoms of xerostomia. Ejection fractions (EF) in the parotid and submandibular glands were calculated. Thyroid disease was diagnosed on the basis of the results of the visual assessment of tracer uptake in the thyroid gland on SGS images as well as serological thyroid function tests. RESULTS Based on the American-European Criteria, 94 patients were diagnosed with SS. Hashimoto's thyroiditis was diagnosed in 63 patients, subacute thyroiditis in 23, subclinical hypothyroidism in five, and Graves' disease in one. There were significant differences in the EF values of the parotid and submandibular glands between patients with TD and those with undetermined diagnoses. CONCLUSIONS More than half of patients with xerostomia exhibited TD. Thyroid assessment by SGS is feasible, and SGS appears to be useful for the patients with xerostomia caused by TD. SGS may be the first imaging modality capable of evaluating both salivary gland function and thyroid gland status in patients with xerostomia. This strategy would make the requirement for additional workup for thyroid disease.

Abstract
Purpose To evaluate dry eye disease and corneal sensitivity in patients with early and active Graves’ ophthalmopathy (GO). Methods A total of 52 eyes of 26 patients with early GO and 74 eyes of 37 age- and sex-matched controls were included in our study. Dry eye disease was assessed based on the criteria of the International Dry Eye Workshop. Diagnosis of early GO was based on the European Group on Graves’ Orbitopathy consensus statement. Clinical Activity Score (CAS) and Werner-NOSPECS Score were determined. Corneal sensitivity was assessed using a Cochet-Bonnet aesthesiometer. Results A total of 67.8% of patients with early GO and 13.5% of healthy controls had ocular surface dryness (p<0.001). The mean Schirmer test score was significantly lower in patients with early GO (12.88 ± 7.94 mm [right eyes] and 14.04 ± 9.00 mm [left eyes]) than in controls (18.08 ± 7.26 mm [right eyes] and 18.05 ± 7.50 mm [left eyes] [p<0.05]). The tear film break-up time was lower in patients by 5.46 seconds and 5.74 seconds in right and left eyes (p<0.001). We also found a significant reduction in corneal sensitivity in patients with early GO (4.16 ± 0.68 [right eyes] and 4.10 ± 0.89 [left eyes]) than in controls (4.70 ± 0.34 [right eyes] and 4.72 ± 0.34 [left eyes] [p<0.05]). The CAS correlated significantly with the Schirmer test (r = −0.60, p = 0.003). Conclusions Dry eye is common in early GO even in the absence of apparent exophthalmos and is associated with CAS and reduced corneal sensitivity.

Abstract
Involvement of several components of the endocrine system has been proposed as significant player in primary Sjogren's syndrome (SS) pathogenesis and clinical expression. Hypoactivity of the hypothalamic-pituitary-adrenal (HPA) axis has been previously demonstrated in patients with primary SS as a result either of a pituitary defect and/or of adrenal gland dysfunction. In support of the latter hypothesis, antibodies to 21-hydroxylase (OH)--a marker of autoimmune adrenal disease--have been detected in sera from approximately one fifth of primary SS patients, in association with B-cell activating cytokines and adrenal hyporesponsiveness. As a result of HPA hypofunction, adrenal androgens and particularly dehydroepiandrosterone-sulfate (DHEA-S) have been reportedly low in primary SS individuals. Epithelial salivary gland cells undergo apoptosis in lack of both estrogens and active androgens. In the absence of a compensatory action of the latter, menopausal status can lead to salivary gland apoptotic process triggering an aberrant immune response. On the other hand, given that salivary gland tissue remodeling has been shown to be under androgenic control, the observed androgen deficiency in these patients might account for the observed alterations in the salivary gland architecture. Heightened serum and salivary gland tissue prolactin levels in primary SS patients have been also suggested as contributors in disease pathogenesis. Finally, autoimmune thyroid disease (ATD) occurs quiet commonly in the setting of primary SS and subclinical hypothyroidism is the main functional abnormality observed in these patients.

Abstract
OBJECTIVES Thyroid dysfunction in the setting of systemic sclerosis (SSc) has been described previously. We aimed to determine the prevalence of anti-thyroid antibodies (ATA) in a large SSc cohort and to ascertain whether they are associated with distinct clinical phenotypes. METHODS A total of 138 patients with SSc [46 with diffuse (dSSc) and 92 with limited scleroderma (lSSc)] and 100 healthy controls (HC) were tested for the presence of ATA [anti-thyroglobulin (anti-Tg) and anti-thyroid peroxidase (anti-TPO) antibodies] using a commercial enzyme-linked immunosorbent assay (ELISA). Clinical and serological data were recorded. RESULTS An increased prevalence of anti-TPO but not anti-Tg antibodies was detected in patients with SSc compared to HC (27.5% vs. 14%, p = 0.016). Of note, a statistically significant increase of anti-TPO was detected only in patients with lSSc compared to HC (32.6% vs. 14%, p = 0.003). No correlations with other clinical features were detected. CONCLUSIONS An increased prevalence of anti-TPO antibodies was identified in patients with lSSc. We propose that ATA testing should be offered to this subgroup of patients.

Abstract
Sjogren's syndrome (SS) is a slowly progressing autoimmune disease, affecting predominantly middle-aged women, with a female to male ratio reaching 9:1. It is characterized by lymphocytic infiltration of the exocrine glands, mainly the lacrimal and salivary glands, resulting in reduced secretory functions and oral and ocular dryness. The syndrome can present alone as primary SS (pSS) or in the context of underlying connective tissue disease as secondary SS (sSS). While the pathogenesis of the disease remains elusive, environmental, genetic and hormonal contributors seem to be involved. Over the last years, compelling evidence has suggested a pivotal role of the epithelium in orchestrating the immune response in the histopathological lesion of Sjogren's syndrome and the term "autoimmune epithelitis" has been proposed as an etiological term. Although the clinical manifestations of pSS patients are mainly those of an autoimmune exocrinopathy, almost half of patients develop extraglandular disease, which may be manifested either by epithelial lymphocytic invasion of lung, liver, or kidney (resulting in interstitial nephritis) or by skin vasculitis, peripheral neuropathy, glomerulonephritis, and low C4 levels. The latter reflect immune-complex mediated disease and confer increased risk for lymphoma development.
