Common mental disorders, including anxiety and depression, are prevalent in patients with inflammatory bowel disease (IBD) and may be associated with adverse outcomes. However, whether increasing psychological co-morbidity, in combination with disease activity, exerts a cumulative effect on prognosis is uncertain.

To assess this in a longitudinal follow-up study.

We collected baseline demographic and IBD-related information, clinical activity using disease activity scores and biochemical activity using calprotectin. Patients were grouped according to the presence or absence of disease activity. Patients in remission or with active disease were subgrouped according to the presence or absence of symptoms of a common mental disorder at baseline. We recorded the occurrence of adverse outcomes over 8.1 years, comparing their occurrence across subgroups using Cox regression.

Among 717 participants with clinical activity data and 187 with clinical and biochemical activity data, rates of adverse outcomes increased with both disease activity and increasing psychological co-morbidity. Rates of flare or glucocorticosteroid prescription, escalation or death were higher with clinical activity (HR 2.89; 95% CI 1.68-4.93 and 2.52; 95% CI 1.55-4.10 and 6.97; 95% CI 2.43-20.0, respectively) or clinical and biochemical activity (HR 7.26; 95% CI 2.86-18.5, 3.62; 95% CI 1.59-8.25 and 57.3; 95% CI 7.58-433, respectively) and two common mental disorders. Rates of hospitalisation (HR 6.20; 95% CI 1.88-20.4) or hospitalisation and/or intestinal resection (HR 7.46; 95% CI 2.41-23.2) were higher with clinical and biochemical activity and two common mental disorders.

Psychological co-morbidity and active disease have a cumulative adverse impact on IBD prognosis.

The patient perspective is essential for assessing disease severity, but it is not always adequately considered. We describe how a comprehensive clinical disease severity index (DSI) for inflammatory bowel disease (IBD) correlates with patient global self-assessment (PGSA).

In an individually linked parallel online survey, physicians provided the DSI, and patients provided self-assessed severity using a global question and visual analog scale (0-100) (PGSA). Mean DSI values by PGSA were calculated with 95% confidence intervals. Pearson correlation (r) and the intraclass correlation coefficient were calculated for PGSA vs DSI. Positive predictive values for identifying severe disease with PGSA categories as a reference were based on a threshold >22 points.

The primary analysis included 89 pairs (46 Crohn's disease [CD], 43 ulcerative colitis [UC]) with strict criteria and 147 pairs when less stringent. Common reasons for exclusion were missing values for albumin or colonoscopy. Mean DSI values showed no clear trend with increasing PGSA in CD but good discrimination between moderate, severe, and very severe PGSA in UC. For PGSA on the visual analog scale, r was 0.54 for CD and 0.59 for UC (difference in means: CD 27.7, UC 13.8; intraclass correlation coefficient: CD 0.48, UC 0.58). A high DSI predicted severe disease in 76.2% of CD and 65.2% of UC.

The DSI showed good discrimination for patient-reported disease severity in UC but performed unsatisfactorily in CD. Correlations were moderate. Further refinement of the DSI is suggested to better reflect the patient perspective.

Background: A significant concern for patients with Inflammatory Bowel Disease (IBD) is predicting and managing disease flares. While healthcare providers rely on biomarkers, providing conclusive patient advice remains challenging. This review explores the role of lifestyle, psychological health, and environmental exposures in the prediction and management of IBD flares. Methods: This review followed PRISMA guidelines (2020). A structured search was conducted in PubMed for articles published between 2012 and 2024, using free and Medical Subject Heading (MeSH) terms for predicting factors in IBD. Inclusion criteria included studies reporting primary data on modifiable clinical or environmental predictors of IBD relapse, excluding studies on post-operative investigations, treatment cessation, and pediatric or pregnant populations. The Mixed Method Appraisal Tool (MMAT) was used to assess the quality of the studies. Results: Out of 2287 identified citations, 58 articles were included. Several modifiable factors influencing disease flares were identified, including psychological stress, sleep disturbances, smoking, and nutrition. Poor sleep quality and mental health were linked to increased flare risks, while smoking was associated with higher relapse rates in Crohn's disease. Environmental exposures, such as heat waves and high-altitude regions, also contributed. Predictive models integrating clinical, lifestyle, and psychological factors showed promising accuracy but require further refinement. Limitations of this review include the potential for publication bias, variability in flare definitions, and limited sample sizes Conclusions: Key predictors of IBD flares include dietary factors, psychological stress, poor sleep quality, and pharmacological influences. Personalized approaches integrating these predictors can optimize disease control and improve patient outcomes.

IBD-Disk is a simple, easy-to-use, and self-administered analogue visual tool for assessing disability in patients with Inflammatory Bowel Disease (IBD). However, it has not yet been validated in Italian. This study aims to validate IBD-Disk in an Italian cross-sectional multicentre study.

This study was conducted in eight IBD centres from February 2023 to October 2023. After forward-backwards translation of IBD-Disk into Italian, patients consecutively completed IBD-Disk (at baseline and after 7 days), IBD-Disability Index (IBD-DI) and IBDQ-32 for quality of life.

We enrolled 767 patients (377, 49,2% CD; 390, 50,8% UC) who completed the IBD-Disk [median score of 30 (IQR=11-52)]. Internal consistency was excellent, with Cronbach's α of 0.92 (95%CI=0.92-0.92). To evaluate the validity, the IBD-Disk was compared with the IBD-DI and IBDQ-32, revealing a significant positive correlation of 0.70 (95% CI=0.66-0.73; p<0.001) and 0.83 (r=0.83, 95% CI=0.80-0.85; p<0.001), respectively. The intraclass correlation coefficient (ICC) was 0.84 (95% CI=0.82-0.86) for test-retest. Female gender, clinically active IBD and the presence of extraintestinal manifestations led to higher IBD-Disk scores.

This study validated the IBD-Disk in a large cohort of Italian IBD patients, demonstrating that it is a valid, reliable and responsive tool for quantifying IBD-related disability. This validation facilitates its integration into the daily clinical management of IBD patients.

Inflammatory bowel disease (IBD), encompassing ulcerative colitis and Crohn's disease, is a heterogeneous chronic condition characterized by periods of relapse and remission. Ulcerative colitis involves inflammation of the colon and rectum mucosa, while Crohn's disease causes deeper, transmural inflammation affecting all four gut layers from the mouth to the anus and can lead to complications such as fistulation. IBD significantly impacts patients' physical and psychological well-being, thus reducing their quality of life (QoL). We aimed to evaluate the effectiveness of nursing intervention facilitated through telephone and email support in improving the quality of life (QoL) of Inflammatory Bowel Disease (IBD) patients.

A pilot comparative observational design with pre-test and post-test assessments was employed, involving 50 participants assigned to either an intervention group (Group A, n = 26) or a control group (Group B, n = 24). Group A received regular telephone consultations and prompt email responses from trained nurses; Group B received standard care. Data were collected at baseline and six months post-intervention (T1) using the Patient-Reported Outcomes Measurement Information System (PROMIS®) and Pittsburgh Sleep Quality Index.

Group A showed significant improvements in anxiety, depression, fatigue, and sleep quality, with p-values indicating the significance of these findings.

Tailored nursing support via remote communication significantly benefits IBD patients by alleviating psychological distress and enhancing their overall well-being, underscoring the importance of integrating such interventions into standard IBD care practices.

To investigate the prevalence and risk factors of psychological symptoms and quality of life (QoL) in early patients with inflammatory bowel disease (IBD).

From September 2021 to May 2022, a unified questionnaire was developed to collect clinical data from early patients with IBD from 42 tertiary care hospitals. The influencing factors of psychological symptoms and poor QoL are screened by logistic regression analysis for constructing model in predicting poor QoL. The consistency index, receiver operating characteristic (ROC) curve, area under the ROC curve (AUC), net reclassification improvement (NRI), integrated discrimination improvement (IDI), calibration curve, and decision curve analysis (DCA) were used to evaluate the performance of the model.

A total of 939 early patients with IBD were surveyed, Among them, 20.3% exhibited anxiety, 21.7% had depression, 57.3% experienced sleep disturbance, and 41.9% reported poor QoL. The factors influencing psychological symptoms varied between ulcerative colitis (UC) and Crohn's disease (CD) patients. The QoL was primarily affected by disease activity, income level and depression. The AUC value of the model in the training group was 0.781 (95% CI: 0.748-0.814). The calibration diagram of the model closely matched the ideal curve. Compared to other prediction models, our model showed superior predictive capability, with NRI and IDI values of 0.324 (95%CI:0.196-0.4513) and 0.026 (95%CI:0.014-0.038), respectively. DCA indicated that the nomogram model could provide clinical benefits.

Early patients with IBD exhibit a high prevalence of psychological symptoms and poor QoL. The nomogram prediction model we constructed demonstrates high accuracy and performance in predicting QoL in early patients with IBD.

The disease severity index (DSI) for inflammatory bowel disease (IBD) combines measures of disease phenotype, inflammatory activity, and patient-reported outcomes. We aimed to validate the DSI and assess its utility in predicting a complicated IBD course.

A multicenter cohort of adults with IBD was recruited. Intraclass correlation coefficients (ICCs) and weighted Kappa assessed inter-rater reliability. Cronbach's alpha measured internal consistency of DSI items. Spearman's rank correlations compared the DSI with endoscopic indices, symptom indices, quality of life, and disability. A subgroup was followed for 24 months to assess for a complicated IBD course. Area under the receiver operating characteristics curve (AUROC) and multivariable logistic regression assessed the utility of the DSI in predicting disease progression.

Three hundred and sixty-nine participants were included (Crohn's disease [CD], n = 230; female, n = 194; mean age, 46 years [SD, 15]; median disease duration, 11 years [interquartile range, 5-21]), of which 171 (CD, n = 99; ulcerative colitis [UC], n = 72) were followed prospectively. The DSI showed inter-rater reliability for CD (ICC 0.93, n = 65) and UC (ICC 0.97, n = 33). The DSI items demonstrated inter-rater agreement (Kappa > 0.4) and internal consistency (CD, α > 0.59; UC, α > 0.75). The DSI was significantly associated with endoscopic activity (CDn=141, r = 0.65, P < .001; UCn=105, r = 0.80, P < .001), symptoms (CDn=159, r = 0.69, P < .001; UCn=132, r = 0.58, P < .001), quality of life (CDn=198, r = -0.59, P < .001; UCn=128, r = -0.68, P < .001), and disability (CDn=83, r = -0.67, P < .001; UCn=52, r = -0.74, P < .001). A DSI of 23 best predicted a complicated IBD course (AUROC = 0.82, P < .001) and was associated with this end point on multivariable analyses (aOR, 9.20; 95% confidence interval, 3.32-25.49).

The DSI reliably encapsulates factors contributing to disease severity and accurately prognosticates the longitudinal IBD course.

Inflammatory bowel disease (IBD) follows a heterogenous disease course and predicting a patient's prognosis is challenging. There is a wide burden of illness in IBD and existing tools measure disease activity at a snapshot in time. Comprehensive assessment of IBD severity should incorporate disease activity, prognosis, and the impacts of disease on a patient. This review investigates the concept of disease severity in adults with IBD to highlight key components contributing to this.

To perform this narrative review, a Medline search was conducted for full-text articles available at 1st March 2024 using search terms which encompassed disease activity assessment, disease severity, prognosis, natural history of Crohn's disease (CD) and ulcerative colitis (UC), and the burden of IBD.

Current methods of disease assessment in IBD have evolved from a focus on the burden of symptoms to one that includes inflammatory targets, genetic, serological, and proteomic profiles, and assessments of quality-of-life (QoL), disability, and psychosocial health. Longitudinal studies of IBD suggest that the burden of illness is driven by disease phenotype, clinical markers of complicated disease course (previous intestinal resection, corticosteroid use, perianal disease in CD, recent hospitalisations in UC), gut inflammation, and the impact of IBD on the patient.

Disease severity in IBD can be difficult to conceptualise due to the multitude of factors that contribute to IBD outcomes. Measurement of IBD severity may better encapsulate the full burden of illness rather than gut inflammation alone at a single timepoint and may be associated with longitudinal outcomes.

In this editorial we comment on the article by Pacheco et al published in a recent issue of the World Journal of Gastroenterology. We focus specifically on the burden of illness associated with perianal fistulizing Crohn's disease (PFCD) and the diagnostic and therapeutic challenges in the management of this condition. Evolving evidence has shifted the diagnostic framework for PFCD from anatomical classification systems, to one that is more nuanced and patient-focused to drive ongoing decision making. This editorial aims to reflect on these aspects to help clinicians face the challenge of PFCD in day-to-day clinical practice.

The fingerprint features of visceral adipose tissue (VAT) are intricately linked to bowel damage (BD) in patients with Crohn's disease (CD). We aimed to develop a VAT fingerprint index (VAT-FI) using radiomics and deep learning features extracted from computed tomography (CT) images of 1,135 CD patients across six hospitals (training cohort, n = 600; testing cohort, n = 535) for predicting BD, and to compare it with a subcutaneous adipose tissue (SAT)-FI. VAT-FI exhibited greater predictive accuracy than SAT-FI in both training (area under the receiver operating characteristic curve [AUC] = 0.822 vs. AUC = 0.745, p = 0.019) and testing (AUC = 0.791 vs. AUC = 0.687, p = 0.019) cohorts. Multivariate logistic regression analysis highlighted VAT-FI as the sole significant predictor (training cohort: hazard ratio [HR] = 1.684, p = 0.012; testing cohort: HR = 2.649, p < 0.001). Through Shapley additive explanation (SHAP) analysis, we further quantitatively elucidated the predictive relationship between VAT-FI and BD, highlighting potential connections such as Radio479 (wavelet-HLH-first-order standard deviation)-Frequency loose stools-BD severity. VAT-FI offers an accurate means for characterizing BD, minimizing the need for extensive clinical data.

Elevated allostatic load (AL) has been associated with the risk and poor prognosis of many chronic diseases. The association between AL and inflammatory bowel disease (IBD) is unknown.

The aim of this study is to investigate the associations between AL and the risk and prognosis of IBD.

We included 326,345 adults and 3767 patients with IBD from the UK Biobank. AL served as the exposure, estimated using the AL biomarker panel, with the primary outcomes including the risk and prognosis of IBD. We used Cox regression models to examine the associations.

High AL biomarker panel was associated with a greater risk of IBD (hazard ratio: 1.19, 95% CI: 1.08-1.31), ulcerative colitis (1.17, 95%CI: 1.04-1.32), and Crohn's disease (1.25, 95%CI: 1.05-1.49). Risk of developing IBD increased by 12% in quartile 2, 20% in quartile 3, and 37% in quartile 4 as AL biomarker panel increased. The all-cause mortality risk in IBD compared with quartile 1 rose by 54% for quartile 2, 72% for quartile 3, and 82% for quartile 4, as AL biomarker panel increased. Similar effects were also observed for ulcerative colitis and Crohn's disease. An increase in AL biomarker panel count was associated with an elevated risk of intestinal resection and colorectal cancer in IBD.

Increased AL is associated with IBD risk, as well as the risks of intestinal resection, colorectal cancer and mortality.

We aimed to evaluate the effectiveness and safety of clinical decision support tool (CDST)-guided initial selective intensive induction therapy (IIT) for patients with Crohn's disease (CD) who were treated with ustekinumab (UST) and to identify those most likely to benefit from IIT.

Patients with active CD were included in this multicenter retrospective study and were categorized as low-, intermediate-, and high-probability responders according to the UST-CDST. IIT was defined as intensive induction by two or three initial doses of weight-based intravenous UST administration. Patients treated with standard therapy (ST) served as controls. The primary end-point was corticosteroid-free clinical remission (CFCR) at Week 24. Secondary end-points included clinical remission, clinical response, endoscopic remission, endoscopic response, and C-reactive protein (CRP) normalization at Week 24. Propensity score adjustments was conducted to ensure comparability.

A total of 296 patients were included. At Week 24, IIT was associated with higher rates of CFCR (72.3% vs 43.0%, p < 0.001), clinical remission (77.3% vs 47.1%, p < 0.001), clinical response (78.1% vs 60.1%, p = 0.001), endoscopic remission (26.1% vs 9.9%, p = 0.024), and endoscopic response (58.6% vs 36.9%, p = 0.018) in low-intermediate-probability responders compared with ST. CRP normalization was comparable between groups. No significant differences were found in any end-points in high-probability responders. No serious adverse events were observed.

The efficacy of IIT was superior to that of ST in patients with predicted poor response to UST, which may be regarded as a novel strategy for stratifying patients at baseline.

Impaired quality of life (QOL) is common in patients with inflammatory bowel disease (IBD). A tool to more quickly identify IBD patients at high risk of impaired QOL improves opportunities for earlier intervention and improves long-term prognosis. The purpose of this study was to use a machine learning (ML) approach to develop risk stratification models for evaluating IBD-related QOL impairments.

An online questionnaire was used to collect clinical data on 2478 IBD patients from 42 hospitals distributed across 22 provinces in China from September 2021 to May 2022. Eight ML models used to predict the risk of IBD-related QOL impairments were developed and validated. Model performance was evaluated using a set of indexes and the best ML model was explained using a Local Interpretable Model-Agnostic Explanations (LIME) algorithm.

The support vector machine (SVM) classifier algorithm-based model outperformed other ML models with an area under the receiver operating characteristic curve (AUC) and an accuracy of 0.80 and 0.71, respectively. The feature importance calculated by the SVM classifier algorithm revealed that glucocorticoid use, anxiety, abdominal pain, sleep disorders, and more severe disease contributed to a higher risk of impaired QOL, while longer disease course and the use of biological agents and immunosuppressants were associated with a lower risk.

An ML approach for assessing IBD-related QOL impairments is feasible and effective. This mechanism is a promising tool for gastroenterologists to identify IBD patients at high risk of impaired QOL.

The disease severity index (DSI) encapsulates the inflammatory bowel disease (IBD) burden but requires endoscopic investigations. This study developed a non-invasive DSI using faecal calprotectin (DSI-fCal) and faecal myeloperoxidase (DSI-fMPO) instead of colonoscopy.

Adults with IBD were recruited prospectively. Baseline biomarker concentrations were used to develop DSI-fCal and DSI-fMPO, and these were correlated with the original DSI, IBD-symptoms, endoscopic activity, and quality-of-life (QoL). Area under the receiver-operating-characteristics curves (AUROC) assessed DSI-fCal/DSI-fMPO as predictors of clinical and biochemical remission at six months (symptom remission and fCal <150 μg/g, respectively), and a complicated IBD-course at 24 months (disease relapse needing escalation of biologicals/immunomodulators/recurrent corticosteroids, IBD-hospitalisations/surgeries). Multivariable logistic regression assessed the utility of DSI-fCal/DSI-fMPO in predicting a complicated IBD-course at 24 months.

In total, 171 patients were included (Crohn's disease=99, female=90, median age=46y (IQR 36-59)). DSI-fCal and DSI-fMPO correlated with the original DSI (r>0.9, p<0.001), endoscopic indices (r=0.45-0.49, p<0.001), IBD-symptoms (r=0.53-0.58, p<0.001) and QoL (r=-0.57-0.58, p<0.001). Baseline DSI-fCal (AUROC=0.79, 95% CI 0.65-0.92) and DSI-fMPO (AUROC=0.80, 95% CI 0.67-0.93) were associated with 6-month clinical and biochemical remission. DSI-fCal (AUROC=0.83, 95% CI 0.77-0.89) and DSI-fMPO (AUROC=0.80, 95% CI 0.73-0.87) performed similarly in predicting a complicated IBD-course to the original DSI (pdifference>0.05). The non-invasive DSI was independently associated with a complicated IBD-course on multivariable analyses (DSI-fCal28, aOR=6.04, 95% CI 2.42-15.08; DSI-fMPO25, aOR=7.84, 95% CI 2.96-20.73).

The DSI-fCal and DSI-fMPO perform similarly in prognosticating the longitudinal disease course as the original DSI, whilst avoiding a need for an endoscopic assessment.

To explore the effects of chronic illness trajectory model (CITM)-based nursing interventions on anxiety, depression, quality of life, medication adherence, and dietary compliance among patients with inflammatory bowel disease (IBD).

A retrospective analysis was performed on 112 IBD patients admitted to Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to December 2023. Patients were divided into two groups: a control group (n=62) receiving routine nursing care, and an observation group (n=50) receiving CITM-based nursing care. Assessments of anxiety, depression, self-care ability, daily living ability, and symptom severity were conducted before and after the intervention.

Post-intervention, the observation group demonstrated significantly higher quality of life scores at 1 and 3 months compared to the control group (both P<0.05). Additionally, the observation group showed improved medication adherence and lower symptom scores, with significant differences (both P<0.05). Anxiety and depression levels were also significantly reduced in the observation group compared to the control group (both P<0.05).

CITM-based nursing intervention significantly enhances self-care abilities, quality of life, and compliance with medication and dietary regimens in IBD patients. Furthermore, it effectively alleviates anxiety and depression, supporting comprehensive management of this chronic disease.

To explore the impact of common gastrointestinal (GI) symptoms on psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease (IBD).

A unified questionnaire was developed to collect clinical data on the mental psychology and quality of life of IBD patients from 42 hospitals in 22 provinces in P. R. China from September 2021 to May 2022. The general clinical characteristics, psychological symptoms, sleep quality, and quality of life of IBD patients with different numbers of GI symptoms were analyzed by descriptive statistical analysis.

A total of 2,478 IBD patients were finally analysed in this study, including 365 without GI symptoms (14.7%), 752 with single symptoms (30.4%), 841 with double symptoms (33.9%), and 520 with three symptoms (21.0%). Compared with patients without GI symptoms, patients with only simple abdominalgia or diarrhea or hematochezia showed significantly higher levels of anxiety and depression and worse quality of life (all P < 0.05). Compared with asymptomatic patients, patients with double symptoms (e.g. abdominalgia plus hematochezia, diarrhea plus hematochezia, abdominalgia plus diarrhea) and patients with three symptoms (abdominalgia, diarrhea, and hematochezia) showed significantly higher levels of anxiety and depression and worse sleep quality and quality of life (all P < 0.05).

Compared with IBD patients without gastrointestinal symptoms, patients with gastrointestinal symptoms were more likely to experience anxiety, depression, sleep disturbances, and poorer quality of life.

Disease Severity Index (DSI) provides comprehensive assessment of bowel damage (BD).

To evaluate DSI in patients with Crohn's disease (CD) at high risk of disease progression, compared to Lémann Index (LI).

Patients with CD in our center were reviewed consecutively between 2017 and 2019. DSI, LI, and complicated CD course were analyzed.

The median LI and DSI of included 300 patients were 1.63 (IQR 1.25-3.13) and 42 (IQR 32-51), respectively. 152 patients (50.7%) experienced a complicated disease course (median 5.1 months; IQR 1.1-20.2). DSI (AUC 0.66; 95% CI 0.60-0.72) better predicted a complicated course of CD over LI (AUC 0.56; 95% CI 0.50-0.63; P = 0.007). The cumulative probability of complicated CD course in severe patients was higher than those with 'mild CD' (P < 0.001). The Cox analysis identified DSI>43 (HR 2.18; 95% CI 1.54-3.09; P < 0.001), B2/3 vs. B1 (HR 2.80; 95% CI 1.99-3.94; P < 0.001), and a higher level of CRP (HR 1.01; 95% CI 1.00-1.02; P = 0.005) as independent prognostic factors for complicated CD. However, LI was not associated with complicated CD (P = 0.164).

Higher DSI was associated with complicated disease outcomes. DSI might play a better role than LI in identifying patients at high risks of disease progression.

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.

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.

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.

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.

We aimed to explore the geographic differences in psychological symptoms, sleep quality, and quality of life (QoL) among adult patients with inflammatory bowel disease (IBD).

A unified questionnaire was developed to collect data on psychological status and QoL of IBD patients from 42 hospitals across 22 provinces, municipalities, and autonomous regions in China's mainland from September 2021 to May 2022.

A total of 2478 patients with IBD were surveyed. The proportions of patients with anxiety (28.5% vs 23.1%), depression (32.3% vs 27.8%), and poor QoL (44.8% vs 32.2%) were significantly higher in patients from the northern region compared to the southern region (all P < 0.05). In the western region, the proportions of patients with anxiety (31.9% vs 23.0%), depression (37.7% vs 26.7%), sleep disturbances (64.5% vs 58.5%), and poor QoL (44.9% vs 34.8%) were significantly higher than in the eastern and central regions (all P < 0.01). Patients from inland regions had significantly higher rates of anxiety (27.1% vs 23.3%), depression (32.5% vs 26.0%), sleep disturbance (62.0% vs 57.7%), and poor QoL (43.5% vs 29.9%) compared to those from coastal regions (all P < 0.05). In economically underdeveloped areas, the proportions of patients with depression (33.1% vs 28.5%) and poor QoL (52.0% vs 32.4%) were significantly higher than in economically (relatively) developed areas (both P < 0.05).

There are significant geographic differences in psychological symptoms, sleep quality, and QoL among Chinese patients with IBD, which might provide valuable insights for global IBD research and clinical practice.

Associations between diet habits and inflammatory bowel disease (IBD) have been widely described. Flavonoids are taken with vegetables, fruits, and green tea. Because of barrier-protective and anti-inflammatory effects, flavonoid consumption (FC) may influence the severity of IBD. The aim of this study was to reveal the role of FC in the course and severity of IBD.

A prospective cohort study including 204 IBD patients (Crohn's disease n = 126, ulcerative colitis n = 78) was conducted between 2016 and 2021. FC was calculated using questionnaires. In addition to standard activity scores and different treatments, a "severity index" was related to individual FC. Differences between groups and odds ratios were analyzed.

Inverse correlation (r = -0.0549; P = .01) between FC and severity of IBD was found. Patients were assigned to 3 different severity index ranges: mild, moderate, and severe disease. FC of patients with severe disease (331 ± 330 mg/week) was less than FC of patients with mild (1404 ± 1086 mg/ week) disease (P < .001). The risk of IBD patients with low FC (1000 mg/week) experiencing overall severe disease was 17 times increased (P < .001) compared to patients with high FC (>1000 mg/week). Patients with UC and low FC had a 9.6-times higher risk for disease progression (P < .001).

Consumption of dietary flavonoids and the overall severity of IBD are inversely correlated. Patients with mild diseases consume higher amounts of flavonoids than patients with severe diseases. Low dietary flavonoids were related to a considerable risk of severe IBD.

Increased disease activity may be a risk factor for sexual dysfunction (SD) in patients with inflammatory bowel disease (IBD). This study investigated associations between objective measures of disease activity and sexual function.

Adults with IBD undergoing ileocolonoscopy were prospectively recruited. Demographic, sexual function (Female Sexual Function Index and International Index of Erectile Function), disease activity (endoscopic, biomarker, and symptoms), psychological symptoms, and quality-of-life data were collected. Rates of SD and erectile dysfunction (ED) were compared between patients with active and inactive inflammation and symptoms using the Fisher's exact test. Logistic regression examined associations between SD and ED, and disease characteristics and psychological symptoms.

A total of 159 participants were included, 97 had Crohn's disease and 85 were women. SD was reported in 36 of 59 and 13 of 59 sexually active women and men, respectively and ED in 22 of 59 sexually active men. Rates of SD and ED were similar between individuals with active and inactive IBD based on endoscopic indices (P > .05) and biomarkers (P > .05). Women with active IBD symptoms experienced significantly higher rates of SD (P < .05), but men did not (P > .05). Multivariable logistic regression identified that symptoms of severe depression (odds ratio, 5.77; 95% confidence interval, 1.59-20.94) were associated with SD in women, and severe anxiety (odds ratio, 15.62; 95% confidence interval, 1.74-140.23) was associated with ED in men.

Objective measures of disease activity are not associated with SD or ED in patients with IBD. Clinicians should consider concomitant psychological symptoms contributing to the sexual health of patients with IBD.

Gender differences were identified in the frequency and clinical presentations of inflammatory bowel disease (IBD) and depressive and anxiety disorders, which are more common in IBD patients than in the general population. The present manuscript provides a critical overview of gender differences in the frequency and clinical course of mood and anxiety disorders in IBD patients, with the aim of helping clinicians provide individualized management for patients. All of the included studies found that IBD patients reported a higher frequency of depressive and anxiety disorders than the general population. These findings should encourage healthcare providers to employ validated tools to monitor the mental health of their IBD patients, such as the Patient Health Questionnaire (PHQ-9). In addition, most studies confirm that women with IBD are more likely than men to develop affective disorders and show that up to 65% of women with IBD have depressive and anxiety disorders. Women with IBD require close mental health monitoring and ultimately a multidisciplinary approach involving mental health professionals. Drug treatment in women should be individualized and medications that may affect mental health (e.g., corticosteroids) should be thoroughly reconsidered. Further data are needed to ensure individualized treatment for IBD patients in a framework of precision medicine.

New therapeutic approaches for ulcerative colitis (UC) are now available, but there is still no robust evidence for predictors of poor outcomes. We aimed to evaluate the factors associated with a chronic active UC disease course.

Data of all UC outpatients followed for at least 3 years after diagnosis between 2005 and 2018 were retrospectively collected. The primary aim was to identify risk factors for chronic active disease 3 years after diagnosis. Moreover, the following variables were investigated: proximal disease extension or disease regression, proctocolectomy, early use of biologics (BIO) or immunomodulators (IMM), hospitalization, colorectal cancer, and adherence. We defined adherence as both, taking the prescribed therapy and constancy in scheduled follow-up visits.

A total of 345 UC patients followed for a median period of 82 months were included. Patients with extensive colitis at diagnosis had a higher rate of chronic active disease 3 years after diagnosis (p<0.012) together with a higher rate of surgery (p<0.001) at maximum follow-up. Patients with pancolitis showed significant disease regression over time (51%) without differences in treatment. The only factor associated with chronic active disease was non-adherence (p < 0.03; OR 0.49, 95% CI: 0.26-0.95). Adherent patients developed chronic active disease (p<0.025) less frequently but did receive more frequent IMM (p<0.045) or BIO (p<0.009) therapy.

Patients diagnosed with pancolitis were more likely to have chronic active disease and to undergo colectomy. The only predictor for developing chronically active UC regardless of disease extension was the lack of adherence to therapy within the first 3 years after diagnosis, underlining the importance of tight control of UC patients and the need to timely identify potential risk factors for non-adherence.

To explore the gender differences in the psychological symptoms, sleep quality, and quality of life of patients with inflammatory bowel disease (IBD).

A unified questionnaire was developed to collect clinical data on the psychology and quality of life of IBD patients from 42 hospitals in 22 provinces in China from September 2021 to May 2022. The general clinical characteristics, psychological symptoms, sleep quality, and quality of life of IBD patients of different genders were analyzed via a descriptive statistical analysis. A multivariate logistic regression analysis was conducted, and independent influencing factors were screened to construct a nomogram to predict the quality of life. The consistency index (C-index), receiver operating characteristic (ROC) curve, area under the ROC curve (AUC), and calibration curve were used to evaluate the discrimination and accuracy of the nomogram model. Decision curve analysis (DCA) was used to evaluate the clinical utility.

A total of 2478 IBD patients (1371 patients with ulcerative colitis (UC) and 1107 patients with Crohn's disease (CD)) were investigated, including 1547 males (62.4%) and 931 females (37.6%). The proportion of anxiety in females was significantly higher than in males (IBD: 30.5% vs. 22.4%, p < 0.001; UC: 32.4% vs. 25.1%, p = 0.003; CD: 26.8% vs. 19.9%, p = 0.013), and there were differences in the severity of anxiety between the genders (IBD: p < 0.001; UC: p < 0.001; CD: p = 0.050). The proportion of depression in females was higher than in males (IBD: 33.1% vs. 27.7%, p = 0.005; UC: 34.4% vs. 28.9%, p = 0.031; CD: 30.6% vs. 26.6%, p = 0.184), and there were differences in the severity of depression between the genders (IBD: p = 0.004; UC: p = 0.022; CD: p = 0.312). The proportion suffering from sleep disturbances among females was slightly higher than among males (IBD: 63.2% vs. 58.4%, p = 0.018; UC: 63.4% vs. 58.1%, p = 0.047; CD: 62.7% vs. 58.6%, p = 0.210), and the proportion of females with a poor quality of life was higher than that of males (IBD: 41.8% vs. 35.2%, p = 0.001; UC: 45.1% vs. 39.8%, p = 0.049; CD: 35.4% vs. 30.8%, p = 0.141). The AUC values of the female and male nomogram prediction models for predicting poor quality of life were 0.770 (95% CI: 0.7391-0.7998) and 0.771 (95% CI: 0.7466-0.7952), respectively. The calibration diagrams of the two models showed that the calibration curves fitted well with the ideal curve, and the DCA that showed nomogram models could bring clinical benefits.

There were significant gender differences in the psychological symptoms, sleep quality, and quality of life of IBD patients, suggesting that females need more psychological support. In addition, a nomogram model with high accuracy and performance was constructed to predict the quality of life of IBD patients of different genders, which is helpful for the timely clinical formulation of personalized intervention plans that can improve the prognosis of patients and save medical costs.
