Psychosomatic Disorders in Patients with Gastrointestinal Diseases: Single-Center Cross-Sectional Study of 1186 Inpatients

Exploring the management and treatment of IBD from the perspective of psychological comorbidities

The prevalence of anxiety, depression, and other psychological comorbidities among patients with inflammatory bowel disease (IBD) significantly exceeds that of the general population. Moreover, a bidirectional relationship exists between psychological comorbidities and IBD. This intricate interplay has substantial clinical implications, impacting treatment adherence, therapeutic efficacy, and disease recurrence rates. In this review, we explore the multifaceted mechanisms through which psychological factors influence IBD progression, treatment response, and prognosis. Specifically, we delve into the involvement of the hypothalamic-pituitary-adrenal axis, autonomic nervous system, enteric nervous system, microbiota-gut-brain axis, systemic inflammatory cytokines, and immune cell function. Additionally, we discuss the potential benefits of antidepressant therapy in mitigating IBD risk and the role of psychotropic drugs in reducing peripheral inflammation. Recognizing and addressing psychological comorbidity is pivotal in comprehensive IBD management. We advocate for the integration of biopsychosocial approaches into IBD treatment strategies, emphasizing the need for innovative psychological interventions as adjuncts to conventional therapies. Rigorous research investigating the impact of antidepressants and behavioral interventions on IBD-specific outcomes may herald a paradigm shift in IBD management.

Allergic Sensitization and Psychosomatic Involvement in Outdoor and Indoor Workers: A Preliminary and Explorative Survey of Motorway Toll Collectors and Office Employees

The incidence of respiratory and cutaneous allergic disorders may be variable if we consider work activity. These disorders are reported in the current literature to have a relevant psychosomatic involvement. The aim of the study was to submit a survey on the self-reported occurrence of allergic respiratory and cutaneous diseases in outdoor and indoor workers to verify the onset or exacerbations of such pathologies, encourage surveillance, and suggest the need for further studies. Two groups of workers were compared when exposed and not exposed to air pollutants. An outdoor population of motorway toll collectors (153 workers; M: 58.03 years old, SD: 6.1; and female prevalence of 66.01%) and an indoor group of office employees (59 workers; mean age 54.44 years, SD: 8.50; and male prevalence of 61.02%) entered the study. The results of three multivariate analyses of the obtained data, investigating contributions of external factors, including age, sex, smoking habits, working type, and seniority, on allergic conditions were significant in both workers' groups. The findings highlighted that age and smoking habits were significant contributors to allergic conditions, both independently and in combination with other factors, such as sex and working type. The data suggest the presence of phenomena related to different etiological domains, as already reported in the literature. Through the collection of these data, it was possible to highlight the need to analyze clinical signs from different perspectives.

Neuropsychological and psychometric parameters in the patients with duodenal ulcer depending on Helicobacter pylori presence

Background. The purpose was to study the effect of Helicobacter pylori (H.pylori) in duodenal ulcer on the neuropsychological and psychometric scores. Materials and methods. We conducted a comprehensive clinical, neurological, neuropsychological, and psychometric examination of 60 patients with duodenal ulcer aged 25–60 (the mean of 39.80 ± 1.29) years. All of them were divided into two groups considering whether H.pylori infection was detected (group 1) or not (group 2). The control group included 30 apparently healthy individuals with no somatic abnormalities. To study psychometric and neuropsychological characteristics, the patients were comprehensively tested, in particular using the Beck Depression Inventory for evaluating the severity of depression, the State-Trait Anxiety Inventory for assessing separate dimensions of state and trait anxiety, the Well-being, Activity, Mood (WAM) questionnaire, the Mini-Mental Health Examination for screening cognitive function, the Schulte tables for evaluating the refocusing speeds and performance distribution. Results. The level of depression in H.pylori-positive duodenal ulcer was significantly higher than with H.pylori-negative duodenal ulcer (p < 0.05). The patients from the group 1 had higher scores of state and trait anxiety and the lower ones of the functional state. The concentration of attention detected by means of the Schulte tables was lower in these patients. A direct correlation was found between the degree of depressive disorders and the number of complaints associated with psycho-emotional disorders in the patients with duodenal ulcer (r = 0.61). We found an inverse correlation (p < 0.05) between the anxiety level and the WAM indices, on the one hand, and between depressive disorders and the WAM indices, on the other hand, in the patients with duodenal ulcer. Depression and anxiety were comorbid in 73.3 % of cases in the group 1 and in 30 % of cases in the group 2. Conclusions. The complaints associated with psycho-emotional disorders occurred in the patients with both H.pylori-positive and H.pylori-negative duodenal ulcer; however, they were more frequent in the group 1. The clinical presentations of depression were observed in both groups, but the depression level was significantly higher in the patients with H.pylori-positive duodenal ulcer (p < 0.05). An increase in anxiety was also found in both groups; however, the rates of state and trait anxiety were higher in the group 1. At duodenal ulcer exacerbation, no matter if H.pylori infection was present or not, the patients had unsatisfactory well-being, low activity, and poor mood. The decreased indices of the functional state self-assessment were detected in the group with H.pylori-positive duodenal ulcer. Using the Schulte tables, we found that a decrease in attention concentration was more evident in the group 1 that in the patients with H.pylori-negative duodenal ulcer. Thus, having conducted the neuropsychological and psychometric testing, we conclude that H.pylori infection has not been the main cause of psycho-emotional disorders in duodenal ulcer, but if the patients were infected, the dysfunction was more severe. It was subject to the increased frequency of psycho-emotional complaints, the deterioration in the patients’ sense of well-being, the increased levels of anxiety and depressive disorders.

Interplay of G-proteins and Serotonin in the Neuroimmunoinflammatory Model of Chronic Stress and Depression: A Narrative Review

INTRODUCTION

This narrative review addresses the clinical challenges in stress-related disorders such as depression, focusing on the interplay between neuron-specific and pro-inflammatory mechanisms at the cellular, cerebral, and systemic levels.

OBJECTIVE

We aim to elucidate the molecular mechanisms linking chronic psychological stress with low-grade neuroinflammation in key brain regions, particularly focusing on the roles of G proteins and serotonin (5-HT) receptors.

METHODS

This comprehensive review of the literature employs systematic, narrative, and scoping review methodologies, combined with systemic approaches to general pathology. It synthesizes current research on shared signaling pathways involved in stress responses and neuroinflammation, including calcium-dependent mechanisms, mitogen-activated protein kinases, and key transcription factors like NF-κB and p53. The review also focuses on the role of G protein-coupled neurotransmitter receptors (GPCRs) in immune and pro-inflammatory responses, with a detailed analysis of how 13 of 14 types of human 5-HT receptors contribute to depression and neuroinflammation.

RESULTS

The review reveals a complex interaction between neurotransmitter signals and immunoinflammatory responses in stress-related pathologies. It highlights the role of GPCRs and canonical inflammatory mediators in influencing both pathological and physiological processes in nervous tissue.

CONCLUSION

The proposed Neuroimmunoinflammatory Stress Model (NIIS Model) suggests that proinflammatory signaling pathways, mediated by metabotropic and ionotropic neurotransmitter receptors, are crucial for maintaining neuronal homeostasis. Chronic mental stress can disrupt this balance, leading to increased pro-inflammatory states in the brain and contributing to neuropsychiatric and psychosomatic disorders, including depression. This model integrates traditional theories on depression pathogenesis, offering a comprehensive understanding of the multifaceted nature of the condition.

Psychiatric disorder and its association with gastrointestinal cancer: a retrospective cohort study with 45,842 patients in Germany

PURPOSE

Psychiatric disorders and cancer are both common, and comorbidity has detrimental impacts on cancer outcomes. Previous studies focus on affective disorders which arise after cancer diagnosis, not on the impact of psychiatric disorders on cancer risk. We investigate the association between psychiatric disorders and subsequent gastrointestinal cancer in a large cohort in Germany.

METHODS

This case-control study used secondary data (electronic medical records) from the national IQVIA Disease Analyzer database. We evaluated the association between previous psychiatric diagnosis in 44,582 matched patients with and without gastrointestinal (GI) cancer. Regression analyses were stratified by psychiatric diagnosis and adjusted by chronic comorbidities and previous psychiatric treatments.

RESULTS

No association between any previous psychiatric disease and GI cancers was found (OR = 0.98 (0.95-1.02 95%CL, p = 0.39). Previous psychosomatic disorder and GI cancer showed a significant negative association (OR: 0.86, 0.81-0.90 95%CL, p < 0.0001). No association was found between previous diagnosis with depression or PTSD and GI cancer. These results remained consistent when including previous psychiatric treatments in the regression analyses.

CONCLUSION

Psychiatric disease was not associated with GI cancer risk. Further investigation into the pathways linking psychiatric disease and cancer needs to be conducted, taking into consideration psychiatric treatments administered, to enhance our understanding of the relationship between these two common and devastating diseases.

Chinese Herbal Medicine for Functional Dyspepsia With Psychological Disorders: A Systematic Review and Meta-Analysis

Background and Aims

Functional dyspepsia (FD) is closely associated with gut–brain interaction disorder (DGBI), characterized by the interaction of gastrointestinal symptoms and central nervous system dysregulation. Chinese herbal medicine (CHM) has a good concurrent effect in the treatment of FD, especially for patients with concurrent psychological disorders. A meta-analysis was designed to evaluate the efficacy and safety of CHMs in the treatment of FD.

Methods

The PubMed, Embase, Cochrane Library, Web of Science, Chinese Biological Medical Database (CBM), Wanfang Data, China National Knowledge Infrastructure (CNKI), and China Science and Technology Journal Database (VIP) were searched to collect randomized controlled trials of FD treated with CHM. The retrieval time limit is from the establishment of the database till 11 April 2022. Two researchers independently searched databases, screened documents, extracted data, and evaluated the risk of bias of included studies. RevMan 5.4 software was used for meta-analysis.

Results

A total of 11 studies including 951 patients were included. The study was divided into two parts. The first part included 5 clinical trials, including 471 patients. The experimental group was treated only with CHM and the control group was only treated with placebo. The results of first part showed that the total effective rate of CHM in the treatment of FD was higher than that in the placebo group (84.5 vs. 49.4%) [relative risk (RR) = 1.76; 95% confidence interval (CI) (1.13, 2.75); P = 0.01]. In addition, CHM treatment could reduce the total symptom score [standardized mean difference (SMD) = −10.05; 95% CI (−13.50, −6.59); Z = 5.70; P < 0.0001] and depression score [SMD = −7.68; 95% CI (−14.43, −0.94); Z = 2.23; P = 0.03]. The second part included 6 clinical trials, including 480 patients. The experimental group was only treated with CHM and the control group was treated with prokinetic agents combined with flupentixol melitracen (deanxit). The results of second part showed that the total effective rate of CHM in the treatment of FD was higher than that of the control group (92.6 vs. 78.8%) [RR = 1.17; 95% CI (1.09, 1.26), P < 0.0001]. In addition, CHM treatment could reduce HAMA score [mean difference (MD) = −3.19; 95% CI (−3.79, −2.59); Z = 10.40; P < 0.00001], HAMD score [MD = −4.32; 95% CI (−6.04, −2.61); Z = 4.94; P < 0.00001], and gastric emptying rate [MD = 12.62; 95% CI (5.84, 19.40); Z = 3.65; P = 0.0003]. The results of the two parts of the meta-analysis showed no serious adverse reactions, and there was no significant difference in the adverse reactions between the experimental group and the control group [MD = 1.14; 95% CI (0.53, 2.42); Z = 0.33; P = 0.74]; [MD = 0.14; 95% CI (0.01, 2.67); Z = 1.30; P = 0.19].

Conclusion

The current evidence shows that CHM treatment has great potential and safety in alleviating the symptoms of FD and improving the psychological disorders of anxiety and depression in patients with FD. Limited by the quantity and quality of the included studies and other biases, the above conclusions need more high-quality studies to be verified.
