Depression, Anxiety, Related Risk Factors and Cognitive Distortion in Korean Patients with Inflammatory Bowel Disease

Profiling the patient with inflammatory bowel disease in the relationship between physical activity and partner/social network status: A post hoc patient-tailored analysis of the "BE-FIT-IBD" study

INTRODUCTION

Normal quality of life is an ultimate target in the therapeutic approach to inflammatory bowel diseases (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC) in the context of which regular physical activity (PA) is often a chimeric parameter that is not standardized in terms of quality/quantity. The study aimed to profile a sample of IBD patients about the relationship between PA-partner status and social network support.

PATIENTS AND METHODS

A post hoc analysis of the "BE-FIT-IBD" study was set up by stratifying the data of PA with that of partner status and the support that the patient's social network (i.e., relatives, friends) provided in inciting the patient to practice regular PA.

RESULTS

In the 219 patients included, there was a greater tendency for patients with stable partners to view the risk of reactivation/worsening of IBD as a barrier to conducting regular PA (p<0.0001). Single patients considered PA more as a protective factor (p=0.045). Patients without a PA-supporting social network retained IBD-related treatment as a PA barrier (p=0.016) and PA as a risk for IBD complications (p=0.01), with less confidence that PA could improve the course of IBD (p<0.001). Rectal syndrome was an IBD-related barrier more represented in patients with PA-deterring social network (p<0.0001).

CONCLUSIONS

These factors are potential targets for recovering the IBD patient's adherence to regular PA.

Multi-frequency electromagnetic radiation induces anxiety in mice via inflammation in the cerebral cortex

Modern life is filled with radiofrequency electromagnetic radiation (RF-EMR) in various frequency bands, while the health risks are not clear. In this study, mice were whole-body exposed to 0.9/1.5/2.65 GHz radiofrequency radiation at 4 W/kg for 2 h per day for 4 weeks to investigate the emotional effects. It was found that the mice showed anxiety but no severe depression. The ELISA results showed a significant decrease in amino acid neurotransmitters (GABA, DA, 5-HT), although acetylcholine (ACH) levels were not significantly altered. Furthermore, Western blot results showed that BDNF, TrkB, and CREB levels were increased in the cerebral cortex, while NF-κB levels were decreased. In addition, pro-inflammatory factors (IL-6, IL-1β, TNF-α) were significantly elevated, and anti-inflammatory factors (IL-4, IL-10) tended to decrease. In conclusion, multi-frequency electromagnetic radiation induces an inflammatory response through the CREB-BDNF-TrkB and NF-κB pathways in the cerebral cortex and causes a decrease in excitatory neurotransmitters, which ultimately causes anxiety in mice.

Psychological symptoms and quality of life in patients with inflammatory bowel disease in China: A multicenter study

AIMS

To investigate the current situation of mental psychology and quality of life (QoL) in patients with inflammatory bowel disease (IBD) in China, and analyze the influencing factors.

METHODS

A unified questionnaire was developed to collect clinical data on IBD patients from 42 hospitals in 22 provinces from September 2021 to May 2022. Multivariate Logistic regression analysis was conducted, and independent influencing factors were screened out to construct nomogram. The consistency index (C-index), receiver operating characteristic (ROC) curve, area under the ROC curve (AUC), calibration curve, and decision curve analysis (DCA) were used to evaluate the discrimination, accuracy, and clinical utility of the nomogram model.

RESULTS

A total of 2478 IBD patients were surveyed, including 1371 patients with ulcerative colitis (UC) and 1107 patients with Crohn's disease (CD). Among them, 25.5%, 29.7%, 60.2%, and 37.7% of IBD patients had anxiety, depression, sleep disturbance and poor QoL, respectively. The proportion of anxiety, depression, and poor QoL in UC patients was significantly higher than that in CD patients (all p < 0.05), but there was no difference in sleep disturbance between them (p = 0.737). Female, higher disease activity and the first visit were independent risk factors for anxiety, depression and sleep disturbance in IBD patients (all p < 0.05). The first visit, higher disease activity, abdominal pain and diarrhea symptoms, anxiety, depression and sleep disturbance were independent risk factors for the poor QoL of patients (all p < 0.05). The AUC value of the nomogram prediction model for predicting poor QoL was 0.773 (95% CI: 0.754-0.792). The calibration diagram of the model showed that the calibration curve fit well with the ideal curve, and DCA showed that the nomogram model could bring clinical benefits.

CONCLUSION

IBD patients have higher anxiety, depression, and sleep disturbance, which affect their QoL. The nomogram prediction model we constructed has high accuracy and performance when predicting QoL.

Are Depression and Anxiety Underdiagnosed in Socially Vulnerable Patients With Inflammatory Bowel Disease?

INTRODUCTION

Depression and anxiety are highly prevalent among individuals with inflammatory bowel disease (IBD); however, little is understood about how social determinants of health (SDOH) may impact mental health diagnoses in this population. The social vulnerability index (SVI) is a publicly available tool that can be used to study SDOH in IBD patients.

METHODS

Home addresses from a retrospective cohort of IBD patients at a single center were used to geocode patients to their individual census tract and corresponding SVI. We used multivariable logistic regression to examine the relationship between SVI and comorbid mental health diagnoses in patients with IBD. Secondarily, data from standardized health questionnaires were then used to determine if patients were adequately screened for depression and anxiety.

RESULTS

In all, 9644 patients were included; 18% had a diagnosis of depression, 21% anxiety, and 32% had a composite of "any mental health diagnosis." Depression (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.02-1.56) but not anxiety (OR, 0.87; 95% CI, 0.71-1.06) nor "any mental health diagnosis" (OR, 1.09; 95% CI, 0.92-1.30) was associated with higher levels of social vulnerability. However, overall rates of screening for depression and anxiety were low (15% and 8%, respectively), with the lowest screening rates among the most socially vulnerable (depression 8.2%, anxiety 6.3%).

CONCLUSIONS

Disparities in the diagnoses of depression and anxiety for socially vulnerable patients with IBD exist. Awareness of these inequities is the first step toward developing interventions to improve mental health screening, eliminate barriers and bias, and promote referrals for appropriate mental health management.

Patient-derived Enterococcus mundtii and its capsular polysaccharides cause depression through the downregulation of NF-κB-involved serotonin and BDNF expression

The genus Enterococcus is commonly overpopulated in patients with depression compared to healthy control in the feces. Therefore, we isolated Enterococcus faecalis, Enterococcus durans, Enterococcus gallinarum, Enterococcus faecium, and Enterococcus mundtii from the feces of patients with comorbid inflammatory bowel disease with depression and examined their roles in depression in vivo and in vitro. Of these Enterococci, E. mundtii NK1516 most potently induced NF-κB-activated TNF-α and IL-6 expression in BV2 microglia cells. NK1516 also caused the most potent depression-like behaviors in the absence of sickness behaviors, neuroinflammation, downregulated brain-derived neurotrophic factor (BDNF), and serotonin (5-HT) levels in the hippocampus of mice. Furthermore, E. mundtii NK1516 reduced the mRNA expression of Htr1a in the hippocampus. Its capsular polysaccharide (CP), but not cytoplasmic components, also caused depression-like behaviors and reduced BDNF and serotonin levels in the hippocampus. Conversely, this was not observed with E. mundtii ATCC882, a well-known probiotic, or its CP. Orally gavaged fluorescence isothiocyanate (FITC)-conjugated NK1516 CP was detected in the hippocampus of mice. The NK1516 genome exhibited unique CP biosynthesis-related genes (capD, wbjC, WecB, vioB), unlike that of ATCC882. These findings suggest that E. mundtii may be a risk factor for depression.

Anxiety and depression in patients with inactive inflammatory bowel disease: The role of fatigue and health-related quality of life

Inflammatory bowel diseases (IBD) are chronic conditions characterized by a remitting-relapsing course. Patients with IBD have an impaired quality of life and are more often affected by anxiety and depression. This study aimed to evaluate the prevalence and severity of anxiety and depression in patients with inactive IBD, and to identify factors associated with them. A total of 132 consecutive patients diagnosed with IBD for over 3 months that were in corticosteroid-free remission at the time of assessment were enrolled in this observational, cross-sectional study. Anxiety, depression, fatigue, and health-related quality of life (HR-QoL) were evaluated using the following self-administered questionnaires: HADS, Functional Assessment of Chronic Illness Therapy-Fatigue, and IBDQ 32. Symptoms of anxiety and depression were considered for HADS-A > 7 points and HADS-D > 7 points, respectively. Out of the 132 patients included, 76 (57.6%) were men. The median patient age was 38 years (interquartile range 30-47). Eighty-three patients (62.9%) were diagnosed with Crohn disease, and 49 (37.1%) with ulcerative colitis. Most of the patients were treated with biologics (85.6%). Anxiety was identified in 34.1% of patients, and two thirds of them (68.9%) had mild symptoms. A lower proportion of patients were presenting symptoms of depression (18.2%), the vast majority (91.7%) having mild forms. In the multivariate analysis, anxiety was significantly associated with fatigue [odds ratio (OR) 4.39, 95% confidence interval (CI): 1.22-15.79, P = .02] and lower HR-QoL (OR 2.46, 95% CI: 1.70-3.91, P < .001), while depression was associated with exposure to multiple biologics (OR 3.33, 95% CI: 1.01-10.97, P = .04) and fatigue (OR 9.70, 95% CI: 1.67-56.27, P = .01). In conclusion, anxiety and depression are highly prevalent in patients with IBD even during the periods of remission. Both anxiety and depression are associated with fatigue. In addition, lower HR-QoL is associated with anxiety and exposure to multiple biologics with depression.

Change of monocytes/macrophages in ulcerative colitis patients with symptoms of anxiety and depression

BACKGROUND AND AIMS

Monocytes/macrophages play important roles in inflammatory bowel disease and depression, but few studies had focused on the change of monocytes/macrophages in ulcerative colitis (UC) patients with psychiatric disorders.

METHODS

UC patients were divided into two groups based on the Hospital Anxiety and Depression Scale (HADS). Demographic and clinical data were captured. Peripheral blood samples and intestinal biopsies were collected for the analysis of monocyte immunophenotype, phagocytic function, and CD4 + T cell differentiation. Transmission electron microscopy was used to observe the ultrastructure of intestinal macrophages.

RESULTS

A total of 139 UC patients were included. 37.41% and 32.37% of UC patients had symptoms of anxiety and depression. In patients with symptoms of anxiety/depression, mayo score, platelet count, erythrocyte sedimentation rate, and endoscopic score, histological scores were significantly higher than those in UC patients without. In patients with symptoms of anxiety/depression, the percentages of CD14 + + CD16 + monocytes and CD14 + CD16++ monocytes were higher, and the phagocytosis was decreased. Patients with symptoms of anxiety/depression had more CD68 + cells and higher M1/M2 ratios in the intestine mucosal layer compared to those without.

CONCLUSIONS

Monocytes and intestinal macrophages from UC patients with anxiety/depression tended to polarize to pro-inflammatory subtypes, and their function was also impaired.

How knowledge time influenced anxiety, depression, stress and quality of life levels in patients suffering from Crohn disease: a cross-sectional multicenter study

BACKGROUND AND AIM OF THE WORK

The diagnosis of Crohn Disease (CD) represents a turning point in the life of patients, which inevitably marks them. The present study represents a direct "feed-back" from patients suffering from Crohn disease, in order to reveal how the diagnosis of CD changed lifestyles and psychological conditions in their patients.

METHODS

An observational, cross sectional, online, snowball sampling study was conducted through participants suffered from CD and belonged to social networks and Facebook groups. For each participant, sampling characteristics, a series of lifestyle habits Before to After the diagnosis of CD and anxiety, depression, and stress conditions were investigated.

RESULTS

A total of 785 participants agreed to participate. As Participants underwent significant challenges in their lifestyles after the CD diagnosis (p<0.001), specifically their reduced their smoking habits, alcohol and drugs intakes and also their diets both in high sugar and fatty compositions. Anxiety and stress levels were not statistical different among participants according to years of the knowledge of their CDs. Meanwhile, as regards depression condition, significantly higher levels were recorded among participants who knew their CD until 5 and 25 years, respectively (p=0.031).

CONCLUSIONS

From the study emerges several aspects of quality of life compromised, a fact supported by the analysis of psychophysical sequelae, which allowed to lay the groundwork for further studies, studying the comorbidity of this disease with other factors. Future randomized controlled trials should deepen the correlation between eating disorders and CD, a link little explored in the literature.

Burden of depression and anxiety among patients with inflammatory bowel disease: results of a nationwide analysis

PURPOSE

The burden of psychiatric disorders is on a rise in inflammatory bowel disease (IBD) patients which has shown to effect medication compliance and overall clinical outcomes. We studied the prevalence of depression and anxiety in IBD patients when compared to individuals with other chronic medical conditions.

METHODS

This is a retrospective cohort study using the United States national inpatient sample of 2016 to 2018. We identified patient encounters with a diagnosis of IBD. Our primary outcome was prevalence of depression and anxiety in IBD patients when compared to general adult population with other chronic medical conditions. We further studied these outcomes in subgroups of patients with ulcerative colitis and Crohn's disease.

RESULTS

A total of 963,619 patient encounters were identified with the diagnosis of IBD between 2016 and 2018, of them 162,850 (16.9%) had depression and 201,685 (20.9%) had anxiety. The prevalence of depression and anxiety was significantly higher in IBD patients in comparison to general population, (16.9% vs 12.3%) and (20.9% vs 15%) respectively (p < 0.001). Association of depression and anxiety was also higher in IBD patients when compared to patients with other chronic conditions like diabetes, metastatic cancer, and coronary artery disease. Crohn's disease and ulcerative colitis were independently associated with increased odds of depression and anxiety and these results were statistically significant (p < 0.001).

CONCLUSIONS

IBD is associated with increased prevalence of depression and anxiety when compared to general population. Association of these psychiatric illnesses with IBD is significantly higher when compared to other chronic medical conditions.

Transplantation of fecal microbiota from patients with inflammatory bowel disease and depression alters immune response and behavior in recipient mice

Gut dysbiosis is closely associated with the occurrence of inflammatory bowel disease (IBD) and psychiatric disorder. Here, to understand the difference of gut microbiota composition and physiological effect between IBD patients with (IBD/D⁺) or without depression (IBD/D⁻), we analyzed the fecal microbiota composition of patients with IBD with (/D⁺) or without depression (/D⁻) and healthy volunteers (HVs) and examined the effects of these fecal microbiota transplantations (FMTs) on the occurrence of systemic inflammation and anxiety/depression in mice. FMTs from patients with IBD/D⁺ or IBD/D⁻ caused IBD-like colitis in the transplanted mice: they increased the myeloperoxidase activity, IL-1β and IL-6 expression, and NF-κB⁺/CD11c⁺ cell population in the colon. Transplantation of the IBD/D⁺ patient feces (IBD/D⁺-F) caused IBD-like colitis more strongly than that of IBD/D⁻-F. FMTs from patients with IBD/D⁺ also caused anxiety-/depression-like behaviors, increased the NF-κB⁺/Iba1⁺ and lipopolysaccharide (LPS)⁺/Iba1⁺ cell populations, and decreased the BDNF⁺/NeuN⁺ cell population in the hippocampus. They increased LPS levels in the blood. FMTs from patients with IBD/D⁻ caused anxiety-like, but not depression-like, behaviors. α-/β-diversities and composition of gut microbiota in IBD-F were different from those of HV feces (HV-F). The Enterobacteriaceae and Enterococcaceae populations and LPS levels were higher in the IBD-F than in the HV-F. The Enterococcaceae population was higher in IBD/D⁺-F vs. IBD/D⁻-F. However, the transplantation of HV-F into mice previously transplanted with IBD/D⁺-F significantly reduced depression-like behaviors, NF-κB⁺/Iba1⁺ and LPS⁺/Iba1⁺ cell populations in the hippocampus, LPS levels in the feces and blood, and IL-1β expression in the colon. These findings suggest that the outbreak of depression/anxiety may be dependent on the systemic inflammation with a leaky gut through the gut dysbiosis-attributable overproduction of bacterial LPS and suppression of tight junction protein expression in patients with IBD.
