Spectrum of Gastrointestinal Manifestations in Joint Hypermobility Syndromes

Post-traumatic stress and joint hypermobility in children and adolescents of Nepal after exposure to an earthquake

A substantial body of literature has traditionally addressed the connection between the exposure to catastrophic events and the development of Post-Traumatic Stress disorder (PTSD), especially in the vulnerable stratum of children and adolescents. However, little is known about their biological predisposing factors, and further research is needed, especially in the context of the recent earthquakes in Turkey and Syria. The data of this study was collected 4 months after the 2015 earthquakes in Nepal, with the objective of providing new evidence to the field and documenting the role of a new potential predisposing factor: the Joint Hypermobility Syndrome (JHS). 941 subjects from three different regions of the country, aged 8-18 years, were assessed in a school-based cross-sectional investigation. PTSD, as the main response variable, was assessed using the Child PTSD Symptom Scale (CPSS) questionnaire and analysed considering three sub-dimensions: the severity of symptoms, the severity of impairment, and both taken together. JHS was assessed using the Screening Questionnaire to detect Hypermobility (SQ-CH) questionnaire. The severity of symptoms was strongly predicted by the distance to the epicentre. Females showed more severe symptomatology, but a lower perturbation in the daily functioning. Younger children reported a greater functional impairment. JHS group showed more severe PTSD than non-JHS group. We observed variability in the severity of PTSD according to previously known risk factors such as the distance to the epicentre, sex, and age. We also found an association between PTSD and JHS, which is discussed in reference to the neuroconnective endophenotype. It might be useful to consider the role of each variable when planning a mass intervention after a disaster.

The spectrum of gastrointestinal functional bowel disorders in joint hypermobility syndrome and in an academic referral center

Joint hypermobility syndrome (JHS) is a non-inflammatory hereditary disorder of connective tissue with varied clinical presentations, including frequent joint dislocations, hyperextensible skin, easy bruising, and abnormal paper-thin scar formation. Many of these patients have unexplained gastrointestinal (GI) symptoms. Our aim was to evaluate the prevalence of JHS in a tertiary gastroenterology motility clinic and the spectrum of functional bowel disorders in JHS patients. In this retrospective case series, we screened the medical records of 277 patients seen over 4 years at an academic GI Motility Center. The patients who met the criteria for JHS by Beighton hypermobility score were evaluated for the presence of functional GI disorders by Rome IV criteria. They also underwent gastric emptying study and glucose breath testing for small intestinal bacterial overgrowth. The prevalence of JHS in the study population was 9.7%. The mean age was 27 years, and 92.5% were female. The symptoms experienced by these patients include nausea/vomiting (89%), abdominal pain (70%), constipation (48%), and bloating (18.5%). The disorders associated with JHS include gastroparesis (52%), irritable bowel syndrome (55.5%), and gastroesophageal reflux disease (30%). Also, 10 patients (37%) were diagnosed with postural hypotension tachycardia syndrome secondary to autonomic dysfunction. Approximately 10% of patients with suspected functional bowel disorders have hypermobility syndrome. Hence, it is crucial to familiarize gastrointestinal practitioners with the criteria utilized to diagnose JHS and the methods to identify physical examination findings related to this condition.

Precision Endoscopy in Peroral Myotomies for Motility Disorders of the Upper Gastrointestinal Tract: Current Insights and Prospective Avenues-A Comprehensive Review

Our review delves into the realm of peroral endoscopic myotomies (POEMs) in the upper gastrointestinal tract (UGT). In recent years, POEMs have brought about a revolution in the treatment of UGT motility disorders. Esophageal POEM, the first to be introduced, has now been validated as the primary treatment for achalasia. Subsequently developed, G-POEM displays promising results in addressing refractory gastroparesis. Over time, multiple endoscopic myotomy techniques have emerged for the treatment of Zenker's diverticulum, including Z-POEM, POES, and hybrid approaches. Despite the well-established efficacy outcomes, new challenges arise in the realm of POEMs in the UGT. For esophageal POEM, the future scenario lies in customizing the myotomy extent to the minimum necessary, while for G-POEM, it involves identifying patients who can optimally benefit from the treatment. For ZD, it is crucial to validate an algorithm that considers various myotomy options according to the diverticulum's size and in relation to individual patients. These challenges align with the concept of precision endoscopy, personalizing the technique for each subject. Within our text, we comprehensively examine each myotomy technique, analyzing indications, outcomes, and adverse events. Additionally, we explore the emerging challenges posed by myotomies within the context of the evolving field of precision endoscopy.

Imaging in Gastroparesis: Exploring Innovative Diagnostic Approaches, Symptoms, and Treatment

Gastroparesis (GP) is a chronic disease characterized by upper gastrointestinal symptoms, primarily nausea and vomiting, and delayed gastric emptying (GE), in the absence of mechanical GI obstruction. The underlying pathophysiology of GP remains unclear, but factors contributing to the condition include vagal nerve dysfunction, impaired gastric fundic accommodation, antral hypomotility, gastric dysrhythmias, and pyloric dysfunction. Currently, gastric emptying scintigraphy (GES) is considered the gold standard for GP diagnosis. However, the overall delay in GE weakly correlates with GP symptoms and their severity. Recent research efforts have focused on developing treatments that address the presumed underlying pathophysiological mechanisms of GP, such as pyloric hypertonicity, with Gastric Peroral Endoscopic Myotomy (G-POEM) one of these procedures. New promising diagnostic tools for gastroparesis include wireless motility capsule (WMC), the 13 carbon-GE breath test, high-resolution electrogastrography, and the Endoluminal Functional Lumen Imaging Probe (EndoFLIP). Some of these tools assess alterations beyond GE, such as muscular electrical activity and pyloric tone. These modalities have the potential to characterize the pathophysiology of gastroparesis, identifying patients who may benefit from targeted therapies. The aim of this review is to provide an overview of the current knowledge on diagnostic pathways in GP, with a focus on the association between diagnosis, symptoms, and treatment.

Antroduodenal motility recording identifies characteristic patterns in gastroparesis related to underlying etiology

BACKGROUND

Gastroparesis (GP) is a gastrointestinal disorder associated with significant morbidity and healthcare costs. GP patients form a heterogeneous population with diverse etiology, and treatment is often challenging due to a poorly understood underlying pathophysiology. The aim of the present study was to assess antroduodenal motility patterns among the different GP etiologies.

METHODS

We reviewed antroduodenal manometry (ADM) recordings of patients with confirmed GP between 2009 and 2019. ADM measurements were evaluated for fed period duration, number of phase III contractions and migrating motor complexes (MMCs), motility index (MI), and presence of neuropathic patterns.

KEY RESULTS

A total of 167 GP patients (142 women, median age 45 [31-57]) were included. The following etiologies were identified: idiopathic n = 101; post-surgery n = 36; and diabetes n = 30. Fed period duration was significantly longer in idiopathic (p < 0.01) and diabetic GP patients (p < 0.05) compared with post-surgery GP patients. Furthermore, the number and duration of phase III contractions and the number of MMCs were significantly lower in idiopathic and diabetic patients compared with post-surgery GP patients (p < 0.01). Likewise, absence of MMCs during 6-h recording was more often observed in idiopathic and diabetes GP patients compared with post-surgery GP patients (resp. p < 0.01 and p < 0.05).

CONCLUSIONS AND INFERENCES

Antroduodenal motility patterns are different among GP etiologies. A dysmotility spectrum was identified with different patterns ranging from post-surgery GP to idiopathic and diabetic GP.

Review article: diagnostic and therapeutic approach to persistent abdominal pain beyond irritable bowel syndrome

BACKGROUND

Persistent abdominal pain (PAP) poses substantial challenges to patients, physicians and healthcare systems. The possible aetiologies of PAP vary widely across organ systems, which leads to extensive and repetitive diagnostic testing that often fails to provide satisfactory answers. As a result, widely recognised functional disorders of the gut-brain interaction, such as irritable bowel syndrome and functional dyspepsia, are often diagnosed in patients with PAP. However, there are a number of less well-known differential diagnoses that deserve consideration.

AIM

To provide a comprehensive update on causes of PAP that are relatively rare in occurrence.

METHODS

A literature review on the diagnosis and management of some less well-known causes of PAP.

RESULTS

Specific algorithms for the diagnostic work-up of PAP do not exist. Instead, appropriate investigations tailored to patient medical history and physical examination findings should be made on a case-by-case basis. After a definitive diagnosis has been reached, some causes of PAP can be effectively treated using established approaches. Other causes are more complex and may benefit from a multidisciplinary approach involving gastroenterologists, pain specialists, psychologists and physiotherapists. This list is inclusive but not exhaustive of all the rare or less well-known diseases potentially associated with PAP.

CONCLUSIONS

Persistent abdominal pain (PAP) is a challenging condition to diagnose and treat. Many patients undergo repeated diagnostic testing and treatment, including surgery, without achieving symptom relief. Increasing physician awareness of the various causes of PAP, especially of rare diseases that are less well known, may improve patient outcomes.

Scleroderma and the Esophagus

The gastrointestinal tract is the second largest organ system in the body and is often affected by connective tissue disorders. Scleroderma is the classic rheumatologic disease affecting the esophagus; more than 90% of patients with scleroderma have esophageal involvement. This article highlights esophageal manifestations of scleroderma, focusing on pathogenesis, clinical presentation, diagnostic considerations, and treatment options. In addition, this article briefly reviews the esophageal manifestations of other key connective tissue disorders, including mixed connective tissue disease, myositis, Sjogren syndrome, systemic lupus erythematosus, fibromyalgia, and Ehlers-Danlos syndrome.

Subtle differences in autonomic symptoms in people diagnosed with hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders

The hypermobile Ehlers-Danlos syndrome (hEDS) GENE study is a multicenter, cohort study with the goal to identify genes associated with hypermobile EDS. Of the 148 people enrolled in the hEDS GENE study, 98 meet the 2017 hEDS criteria, 27 have a hypermobility spectrum disorder (HSD) and 23 are asymptomatic family members. More than 80% of participants are female with an average age of 41 years. Each participant has completed seven questionnaires to quantify disease-related symptomatology. People with hypermobility experience a variety of physical and somatic symptoms, especially in the areas of fatigue, kinesiophobia, gastrointestinal, and autonomic function. These cause a significant decrease in health-related quality of life. The frequency and severity of most symptoms were indistinguishable between participants with hEDS and HSD; however, there were significant differences in autonomic symptoms. Less than 20% of participants had autoantibodies known to be associated with dysautonomia. Subtle symptomatic differences in people meeting the 2017 diagnostic criteria suggest focusing further etiologic studies on autonomic pathways.

Rome IV Functional Gastrointestinal Disorders and Health Impairment in Subjects With Hypermobility Spectrum Disorders or Hypermobile Ehlers-Danlos Syndrome

BACKGROUND & AIMS

Individuals with hypermobility spectrum disorder or hypermobile Ehlers-Danlos Syndrome (HSD/hEDS) are increasingly encountered by gastroenterologists and pose complex clinical challenges. Uncontrolled studies have found functional gastrointestinal disorders (FGIDs) to be common in patients with HSD/hEDS. Some patients have somatic symptoms (medically unexplained symptoms) that might affect FGIDs. We performed a case-control study to determine the prevalence of and factors associated with Rome IV FGIDs in subjects with HSD/hEDS compared with age- and sex- matched population-based controls.

METHODS

An online general health survey was completed by 603 individuals with HSD/hEDS in October 2018 (cases) and 603 matched individuals from the population of the United Kingdom (controls) in 2015. The mean participant age was 39 yrs, and 96% were women. The survey included questions about Rome IV FGIDs, non-GI and non-musculoskeletal somatic symptoms (maximum number, 10), quality of life, medical history and healthcare use. The prevalence of FGIDs was compared between cases and controls, with subsequent logistic regression models - adjusting for the number of somatic symptoms - used to determine the associations for FGIDs in HSD/hEDS compared with controls.

RESULTS

Nearly all subjects (98%) with HSD/hEDS fulfilled symptom-based criteria for 1 or more Rome IV FGIDs, compared with 47% of controls (P < .0001). The gastrointestinal regions most commonly affected by FGIDs in individuals with HSD/hEDS and control subjects were the bowel (90% vs 40% of controls), gastroduodenal (70% vs 13% of controls), esophageal (56% vs 6% of controls), and anorectal (53% vs 9% of controls); P < .0001. A higher proportion of subjects with HSD/hEDS had FGIDs in 2 or more regions (84% vs 15% of controls; P < .0001). Subjects with HSD/hEDS also reported a significantly higher number of non-GI and non-musculoskeletal somatic symptoms (7.1 vs 3.3 in controls), lower quality of life, and greater healthcare use, including abdominal surgeries and medication use (for example, 84% used analgesics compared with 29% of controls). Almost 40% of subjects with HSD/hEDS reported a diagnosis of chronic fatigue syndrome and/or fibromyalgia. Following adjustments for somatic symptoms, the association for FGIDs in subjects with HSD/hEDS was reduced by as much as 4-fold and in some instances was eliminated.

CONCLUSIONS

In a large case-control study of persons with HSD/hEDS, almost all of the cases met criteria for Rome IV FGIDs, incurred considerable health impairment, and had high healthcare use. Patients with HSD/hEDS frequently have somatic symptoms that should be treated to reduce the high burden of gastrointestinal illness in this population.

Joint Hypermobility Syndrome in Patients With Functional Dyspepsia

INTRODUCTION:

The pathophysiology underlying functional dyspepsia (FD) is multifactorial and focuses on gastric sensorimotor dysfunction. Recent studies demonstrated that joint hypermobility syndrome (JHS) is strongly associated with unexplained dyspeptic symptoms in patients attending gastrointestinal clinics. We aimed to study the relationship between symptoms, gastric sensorimotor function, and JHS in FD patients.

METHODS:

Tertiary care FD patients who underwent a gastric barostat study and a gastric emptying breath test with 13C-octanoic acid were recruited for assessment of JHS. The presence of JHS was evaluated by a 2-phase interview and clinical examination that included major and minor criteria of the Brighton classification.

RESULTS:

A total of 62 FD patients (68% women, age 44 ± 1.8 years, and body mass index: 21.7 ± 0.7 kg/m²) accepted to participate in the study. JHS was diagnosed in 55% of FD patients. Assessed symptom profiles during the visit did not differ between the groups. Delayed gastric emptying was not significantly more common in JHS group compared with non-JHS group (JHS group 32% vs non-JHS group 16%, P = 0.31). Prevalence of hypersensitivity to distention (JHS group 24% vs non-JHS group 29%, P = 0.76) and impaired gastric accommodation (JHS group 38% vs non-JHS group 42%, P = 0.79) was similar in patients with or without JHS. No correlations were found between the Beighton hypermobility score and gastric compliance (r = 0.09).

DISCUSSION:

A large subset of this study cohort of tertiary care FD patients has coexisting JHS. We did not identify any specific differences in gastric sensorimotor function between patients with and without JHS. Further prospective research will be required to elucidate the relationship between JHS, a multisystemic disorder with widespread manifestations, and FD symptoms.

The Prevalence of Hypermobility in Children with Irritable Bowel Syndrome and Functional Abdominal Pain Is Similar to that in Healthy Children

OBJECTIVES

To test the hypothesis that the prevalence of joint hypermobility is greater in children with irritable bowel syndrome and functional abdominal pain than in healthy control children and is related to gastrointestinal symptoms and psychosocial distress (anxiety, depression, and somatization).

STUDY DESIGN

Children (irritable bowel syndrome, n = 109; functional abdominal pain, n = 31; healthy control, n = 69), 7-12 years of age completed prospective 2-week pain and stooling diaries and child- and parent-reported measures of anxiety, depression, and somatization. Joint hypermobility was determined using Beighton criteria (score of ≥4 or 6). We also examined possible relationships between Beighton score, race, body mass index, gastrointestinal symptoms, and psychosocial distress.

RESULTS

Beighton scores were similar between groups, as was the proportion with joint hypermobility. Scores were higher in girls (3.1 ± 2.4) than boys (2.3 ± 1.8; P = .004) and decreased with age (P < .001; r = -0.25). Race and body mass index did not impact joint hypermobility prevalence. Beighton scores were not related to abdominal pain or stooling characteristics. Participants with a score of ≥4 and ≥6 had greater somatization and depression by child report (P = .017 and P = .048, respectively). No association was seen for anxiety. There was no significant association between joint hypermobility and psychosocial distress measures per parent report.

CONCLUSIONS

Contrary to the adult literature, the prevalence of joint hypermobility does not differ among children with irritable bowel syndrome, functional abdominal pain, or healthy control children. The presence or severity of joint hypermobility does not correlate with abdominal pain or stooling characteristics. Somatization and depression by child report appear to have a relationship with joint hypermobility.

Recurrent swelling and pain in the abdomen and joints in a patient with hereditary angioedema and Ehlers-Danlos syndrome

A 23-year-old woman was referred to the allergy and immunology clinic for recurrent abdominal, cutaneous and joint swelling and pain with a history of mucosal infections since childhood. Her history and clinical findings were suggestive of two rare and complex disorders, hereditary angioedema (HAE) and Ehlers-Danlos syndrome (EDS). Her recurrent episodes of abdominal and joint pain were initially misattributed to more common diagnoses such as esophagitis, depression and chronic pain syndrome. However, the coexistence of HAE and EDS likely contributed to a delay in diagnoses as the combination of these two rare but overlapping disorders is less understood by physicians. She had persistently low levels of C4 and C1-esterase inhibitor (C1-INH) with low to low-normal C1-esterase function, normal C1Q and no C1Q antibodies. In the setting of recurrent abdominal pain with cutaneous swelling, this supported the diagnosis of HAE type I. The increase in joint extensibility with recurrent shoulder subluxations since childhood was a manifestation of EDS. Although no known genetic mutations were identified for EDS, her diagnosis was confirmed by a geneticist based on her clinical phenotype. Before the diagnosis of HAE and EDS, our patient had at least 100 visits/year to the emergency department/hospitalisations for these recurrent symptoms. After starting on C1-INH replacement therapy, the frequency has decreased 10-fold. She also noted a 70% improvement in her quality of life. Familiarity with these rare disorders will assist healthcare providers in recognising HAE and EDS and include them as part of their differential diagnoses. Early diagnosis is important for a patient's well-being as both these chronic disorders have been associated with poor quality of life. Additionally, proper diagnoses will reduce healthcare costs by preventing unnecessary procedures due to misdiagnoses. Proper treatment will help to decrease hospitalisations and avoidance of life-threatening consequences (such as asphyxiation from fatal laryngeal attacks of HAE and rupture of aneurysms in EDS).

Joint Hypermobility Syndrome Affects Response to a Low Fermentable Oligosaccharide, Disaccharide, Monosaccharide and Polyol Diet in Irritable Bowel Syndrome Patients: A Retrospective Study

BACKGROUND

The low fermentable oligosaccharide, disaccharide, monosaccharide and polyol (FODMAP) diet causes significant clinical improvement in patients with irritable bowel syndrome (IBS). Joint hypermobility syndrome (JHS), defined as musculoskeletal symptoms in a hypermobile individual in the absence of systemic rheumatological disease, may be associated with functional gastrointestinal symptoms, including IBS. The aim of this study is to examine whether JHS can affect the response to the low FODMAP diet in patients with IBS.

METHODS

In this retrospective study, we included patients with IBS according to Rome III criteria who had followed a low FODMAP diet. Symptoms scores were measured before and after the low FODMAP diet.

RESULTS

A total of 165 patients (130 females, age 44 ± 14 years) were included. Diarrhea predominant IBS (IBS-D) was present in 40.6% of our patients while JHS was present in 21.2%. The score for abdominal pain was higher for JHS compared to non-JHS prior to intervention (P = 0.011). Symptoms improved in both groups of patients after a low FODMAP diet (P < 0.0001). The largest effects were shown with significant decreases of the average score and bloating. When broken down by JHS and IBS type, a low FODMAP diet significantly improved pain, bloating, diarrhea, constipation, and the average score with the largest effect in JHS/constipation predominant IBS (IBS-C), JHS/mixed IBS and unclassified IBS (IBS-M), JHS/IBS-D, non-JHS/IBS-C and JHS/IBS-M, respectively.

CONCLUSIONS

Our study suggests that a low FODMAP diet has a greater effect on IBS symptoms in JHS than non-JHS patients.
