The impact of gastroesophageal reflux disease symptoms in scleroderma: effects on sleep quality

Prevalence and Outcomes of Gastrointestinal Manifestations in an Australian Scleroderma Cohort

OBJECTIVE

The gastrointestinal tract (GIT) is the most commonly affected internal organ in systemic sclerosis (SSc). We sought to determine the prevalence and impact of GIT symptoms on survival and patient-reported outcomes.

METHODS

A total of 907 consecutive patients from the Australian Scleroderma Cohort Study who had prospectively completed the University of California, Los Angeles, Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 Questionnaire (UCLA GIT) between 2015 and 2021 were included. The associations between UCLA GIT scores and physical function (Scleroderma Health Assessment Questionnaire), quality of life (QoL; Short Form 36), mood (Patient-Reported Outcomes Measurement Information System [PROMIS] anxiety and depression domains), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue score), and employment were investigated using multivariable population-averaged panel models using generalized estimating equations (GEEs). Kaplan-Meier curves and multivariable Cox proportional hazard regression models were used to evaluate survival according to total UCLA GIT scores.

RESULTS

GIT symptoms were reported in 87% of participants, with 46% to 52% reporting moderate to very severe symptoms of reflux, distension, diarrhea, and constipation. Higher total UCLA GIT scores were associated with worse QoL, physical function, fatigue, anxiety, and depression (P < 0.001). In the multivariable GEE analysis, moderate and severe to very severe total scores, reflux scores, and distension scores were associated with worse physical function, QoL, fatigue, anxiety, and depression compared to mild scores (P < 0.05). Patients with severe total scores and diarrhea scores were more likely to be unemployed compared to those with mild scores (P < 0.05). UCLA GIT total scores were not independently associated with death in our cohort.

CONCLUSION

GIT manifestations are common in SSc and negatively impact QoL, physical function, and employment but are not directly associated with increased death.

Sleep Disorders in Connective Tissue Diseases-Coexisting Diseases or Disease Components?

This comprehensive review examines the complex relationship between sleep disorders and rheumatic diseases, supported by findings from the latest research articles. It encompasses various rheumatic conditions, including rheumatoid arthritis, systemic lupus erythematosus, and systemic sclerosis. The review reveals the bidirectional relationship between sleep disorders and these diseases, emphasizing their impact on disease progression and quality of life. Conventional and alternative therapeutic interventions for connective tissue diseases are presented, focusing on improving sleep quality and alleviating rheumatic symptoms. The role of pro-inflammatory cytokines and their potential modulation through pharmacological agents is also discussed. In the treatment of sleep disorders, various options are proposed, such as cognitive behavioral therapy for insomnia, physical activity, dietary modifications, and alternative approaches like reflexology and acupuncture. Thus, this review offers a nuanced understanding of the connection between sleep disorders and rheumatic diseases, supported by evidence from diverse studies. Such an approach is particularly important because it enhances sleep quality for overall patient well-being in the holistic management of rheumatic conditions.

Bidirectional correlation between gastroesophageal reflux disease and sleep problems: a systematic review and meta-analysis

Objectives

Gastroesophageal reflux disease (GERD) and sleep problems are highly prevalent among the general population. Both them are associated with a variety of psychiatric disorders such as depression and anxiety, which is highlighting an underexplored connection between them. This meta-analysis aims to explore the association between sleep problems and GERD.

Methods

We conducted a comprehensive search on PubMed, Cochrane Library, Embase, and Web of Science, using Medical Subject Headings (MeSH) and keywords, covering articles from the inception of the databases until August 2023. Stata statistical software, version 14.0, was utilized for all statistical analyses. A fixed-effects model was applied when p > 0.1 and I2 ≤ 50%, while a random-effects model was employed for high heterogeneity (p < 0.1 and I2 > 50%). Funnel plots and Egger's test were used to assess publication bias.

Results

Involving 22 studies, our meta-analysis revealed that insomnia, sleep disturbance, or short sleep duration significantly increased the risk of GERD (OR = 2.02, 95% CI [1.64-2.49], p < 0.001; I2 = 66.4%; OR = 1.98, 95% CI [1.58-2.50], p < 0.001, I2 = 50.1%; OR = 2.66, 95% CI [2.02-3.15], p < 0.001; I2 = 62.5%, respectively). GERD was associated with an elevated risk of poor sleep quality (OR = 1.47, 95% CI [1.47-1.79], p < 0.001, I2 = 72.4%), sleep disturbance (OR = 1.47, 95% CI [1.24-1.74], p < 0.001, I2 = 71.6%), or short sleep duration (OR = 1.17, 95% CI [1.12-1.21], p < 0.001, I2 = 0).

Conclusion

This meta-analysis establishes a bidirectional relationship between four distinct types of sleep problems and GERD. The findings offer insights for the development of innovative approaches in the treatment of both GERD and sleep problems.

Sleep quality and clinical association with sleep disturbance in systemic sclerosis

BACKGROUND

Poor sleep quality is a common and potentially debilitating problem in systemic sclerosis (SSc). To date, no data clarifies the potential factors related to poor sleep quality and the clinical associations with sleep disturbance among Thais with SSc-mainly the diffuse cutaneous SSc (dcSSc) subset. We aimed to evaluate sleep quality and identify the clinical association with sleep disturbance among SSc patients.

METHODS

A cross-sectional study was conducted between May 2021 and September 2021. Adult SSc patients were enrolled at the Scleroderma Clinic, Khon Kaen University, Thailand. All patients had their neck circumference measured, underwent airway evaluation using the Mallampati classification, had sleep quality assessed using the Pittsburgh Sleep Quality Index (PSQI), and the Berlin and Patient Health Questionnaire-9 completed. In addition, the clinical association with poor sleep quality (or sleep disturbance) was investigated using the PSQI.

RESULTS

A total of 88 patients were enrolled. Forty-eight (54.6%) patients experienced poor sleep quality (95%CI 43.6-65.2). Digital ulcers and dyspepsia were associated with poor sleep quality as per a logistic regression (OR 10.73: 95%CI 1.09-106.15 and 4.60: 95%CI 1.01-20.89), respectively. Overall pain-evaluated using the visual analog scale (VAS)-was positively correlated with the PSQI score (Rho 0.2586; p = 0.02).

CONCLUSION

Around half of the SSc patients reported poor sleep quality, and the significantly associated factors were digital ulcers and dyspepsia. The PSQI scores positively correlated with overall pain as evaluated by VAS. With early assessment and treatment of digital ulcers, stomach symptoms, and pain control, sleep problems might be reduced among SSc patients.

Gastrointestinal Tract Considerations: Part II: How Should a Rheumatologist Best Manage Common Lower Gastrointestinal Tract Complaints in Systemic Sclerosis?

Lower gastrointestinal (GI) symptoms are a frequently encountered problem for clinicians managing patients with systemic sclerosis. The current management practices are focused on the treatment of symptoms with little information available on how to use GI investigations in daily practice. This review demonstrates how to integrate the objective assessment of common lower GI symptoms into clinical care with the aim of guiding clinical decision making. Understanding the type of abnormal GI function that is affecting a patient and determining which parts of the gut are impacted can help clinicians to target therapy more precisely.

Gastrointestinal Tract Considerations Part I

The upper gastrointestinal (GI) tract is frequently involved in systemic sclerosis (SSc) and may impact quality of life, physical function and survival. Although we are currently very proactive in terms of screening for heart and lung involvement, patients with SSc are not routinely screened for GI involvement. This review details the available investigations for common upper GI symptoms in SSc, including dysphagia, reflux and bloating and provides advice as to how to integrate these investigations into current clinical care.

Fatigue in ANCA-associated vasculitis (AAV) and systemic sclerosis (SSc): similarities with Myalgic encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). A critical review of the literature

INTRODUCTION

Persistent debilitating fatigue is a frequent complaint in patients with systemic autoimmune rheumatic diseases (SARDs). Fatigue is, however, frequently overlooked in the clinic, and patients who successfully achieve remission of their disease, often still have a lowered quality of life due to its persistence. How similar is this fatigue to Myalgic encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), what is this fatigue associated with, and what tools/approaches (if any), have resulted in the improvement of fatigue in these patients is poorly defined.

AREAS COVERED

Similarities between the pathophysiology of ME/CFS, systemic sclerosis (SSc) and primary systemic vasculitides (PSV) are discussed, followed by an in-depth review of the prevalence and correlates of fatigue in these diseases. The authors reviewed literature from MEDLINE, APA PsycInfo, Embase, and CINAHL.

EXPERT OPINION

Persistent fatigue is a prominent feature in SARDs and may not be associated with components commonly associated with disease activity and/or progression. Immune and metabolic commonalities exist between ME/CFS, SSc, and PSVs - suggesting that common pathways inherent to the diseases and fatigue may be present. We suggest that patients with features of ME/CFS need to be identified by treating physicians, as they may require alternative approaches to therapy to improve their quality of life.

Gastrointestinal manifestations of systemic sclerosis: An updated review

Systemic sclerosis is an autoimmune disease characterized by vascular disease, fibrosis of the skin, and internal organ dysfunction. Gastrointestinal involvement is the most frequent complication of internal organs, impacting up to 90% of patients. Gastrointestinal involvement can affect any region of the gastrointestinal tract from the mouth to the anus, with a predominance of disorders being observed at the level of the upper digestive tract. The gastrointestinal involvement primarily involves the esophagus, small bowel, and rectum. The severity of gastrointestinal involvement affects quality of life and is a marker of worse prognosis and mortality in these patients. In this review, we describe the current findings regarding gastrointestinal involvement by this entity.

Progression of gastrointestinal symptoms over time in patients with systemic sclerosis

Up to 90% of patients with systemic sclerosis (SSc) develop gastrointestinal (GI) symptoms. To evaluate whether GI symptoms and quality of life in patients with SSc demonstrate longitudinal stability. Consecutive patients with SSc (n = 100) completed the validated university of California at Los Angeles scleroderma clinical trial consortium gastrointestinal tract 2.0 (GIT) instrument and completed the same instrument approximately 5 years later. Comparison was made between patients with diffuse (dcSSc) and limited (lcSSc) subtypes and duration of disease of less than or greater than 5 years. GIT scores were calculated and analyzed for differences. 37 patients with dcSSc and 63 patients with lcSSc were included. Social functioning score significantly improved over time [0.44 (0.59)-0.31 (0.47); P = 0.003]. Total GIT scores were lower in patients with diffuse [0.51 (0.41)] compared with limited [(0.72 (0.53); P = 0.029] disease at both baseline and follow-up. Social functioning improved similarly in both dcSSc and lcSSc over time (P = 0.004). GIT Total scores increased in 27% (27/100) of patients and did not change or improved in 73% (73/100). Patients with worsening GI status had significantly increased scores on all GIT subscales. A lower body-mass index at baseline was significantly associated with worsening GIT Total score (OR 1.22; 95% CI 1.07-1.39; P < 0.001). Patients with SSc generally demonstrate longitudinal stability or improvement in their GI symptoms, but a subset of patients experience worsening of GI symptoms and negative impacts on GI-related quality of life.

Gastrointestinal involvement in systemic sclerosis: an update

PURPOSE OF REVIEW

This review provides important updates in systemic sclerosis (SSc)-related gastrointestinal disease, specifically focusing on the most recent literature.

RECENT FINDINGS

In the past year, several studies were published that present interesting insights into SSc and gastrointestinal disease. Studies focusing on newly identified risk factors, novel approaches to diagnosis and assessment of disease activity, survival and quality of life demonstrate progress in our understanding of this challenging area. Additional data on specific SSc gastrointestinal-related topics, such as the link between gastrointestinal and pulmonary disease, nutrition, and the microbiome, are also now available.

SUMMARY

SSc gastrointestinal disease is heterogeneous in its clinical presentation, which presents a challenge in diagnosis and management. In the past year, several studies have evaluated risk factors and clinical features associated with specific gastrointestinal complications in SSc. Objective gastrointestinal testing may help to identify specific SSc gastrointestinal subgroups and provide diagnostic accuracy to guide targeted therapies. Survival in very early SSc is affected by the severity of gastrointestinal involvement. Other important gastrointestinal subsets, including patients with esophageal disease and interstitial lung disease, should carefully be considered when developing a management plan for this patient population.
