Inflammatory Bowel Disease in Children and Adolescents

Children and Young Adults With Inflammatory Bowel Disease Have an Increased Incidence and Risk of Developing Mental Health Conditions: A UK Population-Based Cohort Study

BACKGROUND

The burden of mental health conditions in children and young adults with inflammatory bowel disease remains unclear. We assessed this using a primary care database in the United Kingdom.

METHODS

A retrospective, observational study compared children and young adults with incident inflammatory bowel disease 5 to 25 years of age (2010-2020) against population control subjects. Outcomes comprised incident depression, anxiety disorder, eating disorders, body image disorders, attention-deficit disorders, behavioral disorders, adjustment disorders, acute stress disorder, schizophrenia, bipolar disorder, posttraumatic stress disorder, self-harm, parasuicide (including suicide), and sleep disturbance. The any mental health condition category comprised any of these conditions.

RESULTS

A total of 3898 young patients with incident inflammatory bowel disease were matched to 15 571 control subjects. Inflammatory bowel disease patients were significantly more likely to develop new posttraumatic stress disorder (adjusted hazard ratio [aHR], 2.47; 95% confidence interval [CI], 1.23-4.94), eating disorders (aHR, 1.85; 95% CI, 1.05-3.26), self-harm (aHR, 1.49; 95% CI, 1.00-2.21), sleep disturbance (aHR, 1.40; 95% CI, 1.15-1.71), depression (aHR, 1.34; 95% CI, 1.16- 1.56), anxiety (aHR, 1.25; 95% CI, 1.06-1.48), and any mental health condition (aHR, 1.28; 95% CI, 1.12-1.46). Male inflammatory bowel disease patients aged 12 to 17 years, and patients with Crohn's disease appear to have the highest risk for developing new mental health conditions.

CONCLUSIONS

Young inflammatory bowel disease patients have a significantly higher incidence and risk of new mental health conditions. Mental health remains a critically overlooked aspect of inflammatory bowel disease patient management. Further research into identifying optimal monitoring tools and support for these patients is required to improve patient care. The study protocol was specified and registered a priori.ClinicalTrials.gov study identifier: NCT05206734.

Factors promoting and hindering resilience in youth with inflammatory bowel disease: A descriptive qualitative study

AIM

To explore factors promoting and hindering resilience in youth with inflammatory bowel disease (IBD) based on Kumpfer's resilience framework.

DESIGN

A descriptive qualitative study design with an interpretative approach was used.

METHODS

Participants consisted of 10 youths with IBD from a tertiary hospital in Beijing (China) recruited using the purposive sampling method. Data were collected by semi-structured interviews from December 2020 to March 2021. The directed content analysis was performed for data analysis.

RESULTS

Both promoting factors and hindering factors could be divided into personal factors and environmental factors. Thirteen themes were identified. The promoting factors included acceptance of illness, strict self-management, previous treatment experience, life goals, family support, medical support and peer encouragement. Stigma, lack of communication, negative cognition, societal incomprehension, economic pressure and academic and employment pressure were hindering factors.

CONCLUSION

Health care professionals need to develop greater awareness of factors, stemming from both the individual and the outside world, that hinder or promote resilience in order to aid young patients with IBD. Building targeted nursing measures to excavate the internal positive quality of patients, provide external support and promote the development of resilience.

Inflammatory bowel disease (ulcerative colitis type) severity shows inverse correlation with semen parameters and testosterone levels

Individuals with inflammatory bowel disease (IBD) have been reported to be at an increased risk of infertility and sexual dysfunction. Although the relationship between them remains unclear, IBD severity is suspected to affect hormone levels and fertility. To analyze the impact of IBD severity on semen parameters and sex hormone levels in ulcerative colitis-type IBD (UC-IBD), we conducted a cross-sectional study involving 120 patients with UC-IBD in Adam Malik General Hospital, Medan, Indonesia. The patients were classified into three groups based on the Mayo score for UC, followed by a comparison of various semen and hormone parameters among these groups. In addition to the cross-sectional analysis, a simple correlation test was conducted irrespective of the patient grouping. Sperm concentration, motility, and morphology were found to decline significantly with an increase in IBD severity. Without classifying patients with IBD into subgroups, the Mayo score showed negative correlations with sperm concentration ( r = -0.375, P < 0.0001), rapid progressive motility ( r = -0.660, P < 0.0001), free testosterone ( r = -0.732, P < 0.0001), and total testosterone ( r = -0.721, P < 0.0001), and positive correlations with immotile sperm ( r = 0.660, P < 0.0001), abnormal morphology ( r = 0.657, P < 0.0001), and sex hormone-binding globulin (SHBG; r = 0.278, P = 0.002). Sperm concentration, motility, and morphology declined significantly with the severity of IBD. This study suggests a significant negative impact of IBD severity on semen quality and sex hormones.

Impact of mental health comorbidity in children and young adults with inflammatory bowel disease: a UK population-based cohort study

OBJECTIVE

To evaluate the impact of mental health comorbidity in children and young adults with inflammatory bowel disease (IBD).

DESIGN

Retrospective observational study.

SETTING

Representative population, routinely collected primary care data from the UK Optimum Patient Care Research Database (2015-2019).

PARTICIPANTS

Patients with IBD aged 5-25 years with mental health conditions were compared with patients with IBD of the same age without mental health conditions.

PRIMARY AND SECONDARY OUTCOME MEASURES

Outcomes comprised quality-of-life indicators (low mood, self-harm, parasuicide, bowel symptoms, absence from school or work, unemployment, substance use and sleep disturbance), IBD interventions (medication, abdominal surgery, stoma formation and nutritional supplements) and healthcare utilisation (primary care interactions and hospital admissions).

RESULTS

Of 1943 individuals aged 5-25 years with IBD, 295 (15%) had a mental health comorbidity. Mental health comorbidity was associated with increased bowel symptoms (adjusted incident rate ratio (aIRR) 1.82; 95% CI 1.33 to 2.52), sleep disturbance (adjusted HR (aHR) 1.63; 95% CI 1.02 to 2.62), substance use (aHR 3.63; 95% CI 1.69 to 7.78), primary care interactions (aIRR 1.33; 95% CI 1.12 to 1.58) and hospital admissions (aIRR 1.87; 95%CI 1.29 to 2.75). In individuals ≥18 years old, mental health comorbidity was associated with increased time off work (aHR 1.55; 95% CI 1.21 to 1.99).

CONCLUSIONS

Mental health comorbidity in children and young adults with IBD is associated with poorer quality of life, higher healthcare utilisation and more time off work. It is imperative that affected young patients with IBD are monitored and receive early mental health support as part of their multidisciplinary care.

Inflammatory Bowel Disorders in Children and Adolescents: Management of Care for Students at School

Inflammatory bowel disease (IBD) is an umbrella term for two chronic and recurrent digestive conditions, Crohn's disease (CD) and ulcerative colitis (UC). Both are characterized by chronic inflammation of the gastrointestinal tract but not caused by infection or other identifiable causes. Childhood IBD often leads to a more extensive disease and a more aggressive course than adult-onset disease. Since children spend a lot of time at school, children with IBD may experience symptoms while at school. As a result, school nurses play a crucial role in identifying and managing students with IBD within their school or school district. It is important for a school nurse to understand the etiology, symptoms, and management of IBD to provide management of care at school.

Mitogen-Activated Protein Kinases (MAPKs) and Enteric Bacterial Pathogens: A Complex Interplay

Diverse extracellular and intracellular cues activate mammalian mitogen-activated protein kinases (MAPKs). Canonically, the activation starts at cell surface receptors and continues via intracellular MAPK components, acting in the host cell nucleus as activators of transcriptional programs to regulate various cellular activities, including proinflammatory responses against bacterial pathogens. For instance, binding host pattern recognition receptors (PRRs) on the surface of intestinal epithelial cells to bacterial pathogen external components trigger the MAPK/NF-κB signaling cascade, eliciting cytokine production. This results in an innate immune response that can eliminate the bacterial pathogen. However, enteric bacterial pathogens evolved sophisticated mechanisms that interfere with such a response by delivering virulent proteins, termed effectors, and toxins into the host cells. These proteins act in numerous ways to inactivate or activate critical components of the MAPK signaling cascades and innate immunity. The consequence of such activities could lead to successful bacterial colonization, dissemination, and pathogenicity. This article will review enteric bacterial pathogens' strategies to modulate MAPKs and host responses. It will also discuss findings attempting to develop anti-microbial treatments by targeting MAPKs.

Chronic Nonbacterial Osteomyelitis and Inflammatory Bowel Disease: A Literature Review-Based Cohort

Background: Chronic nonbacterial osteomyelitis (CNO) is a rare autoinflammatory bone disorder that mainly involves children and adolescents. The association with other inflammatory disorders, such as inflammatory bowel disease (IBD), psoriasis, and arthritis, has been reported in the literature. In particular, the relationship between bone and intestinal inflammation is still poorly understood. For this purpose, our review aims to describe the cases reported in the literature concerning this association and to compare them with data from our single-center cohort of patients. Methods: We conducted a literature review of published cases of CNO associated with IBD. Eligible articles were identified through a Medline search in the PubMed database until December 2022. We retrospectively reviewed medical records of patients with CNO referred to G. Pini Hospital and compared them with the literature-review-based cohort. Results: Fifty-seven patients with a defined diagnosis of CNO and associated IBD were described in the literature (female 55%). The median age of onset of the disease (CNO or IBD) was 11 years. In 32/53 (60%), a diagnosis of Crohn’s disease (CD) was made, while 18 (34%) patients were classified as suffering from ulcerative colitis (UC) and 3 (6%) from undifferentiated IBD. The diagnosis of CNO preceded the diagnosis of IBD in 59% of cases; while in 24%, IBD anticipated CNO; and in 17%, the two conditions appeared simultaneously. The median time between the two events was 24 months. In our Italian cohort (n = 23 patients), no diagnosis of IBD was made. No significant differences were found when comparing clinical and demographical characteristics of the Italian vs. review-based cohort, except for a significant involvement of rachis in the Italian group. Conclusions: The correlation between autoinflammatory bone disease and intestinal inflammation should be further investigated. It is essential to promote awareness among pediatric rheumatologists and gastroenterologists about this possible association to facilitate the diagnosis and better optimize treatment.

Vitamin D therapy in pediatric patients with inflammatory bowel disease: a systematic review and meta-analysis

BACKGROUND

There is some evidence for the role of vitamin D deficiency in the pathogenesis of inflammatory bowel disease (IBD) in the pediatric population. However, the results are contradictory. Therefore, we have conducted a systematic review and meta-analysis to evaluated the effect of vitamin D on pediatric patients with IBD.

METHODS

We carried out a systematic search in databases from inception until 20 January 2022. We included all relevant articles that evaluate the efficacy and safety of vitamin D on disease activity, inflammatory factors, and vitamin D and calcium levels in pediatric patients with IBD. Random effects models were used to combine the data. The main outcomes were then analyzed using weight mean difference (WMD) and respective 95% confidence interval (CI).

RESULTS

Fifteen treatment arms met the eligibility criteria and were included. Pooled estimates indicated that intervention with vitamin D has a significantly beneficial effect on 25-hydroxyvitamin D3 [25(OH) D3] (pooled WMD of 17.662 ng/mL; CI 9.77-25.46; P < 0.001), calcium (pooled WMD of 0.17 mg/dL; CI 0.04-0.30; P = 0.009), and inflammatory factors including C-reactive protein (CRP) (pooled WMD of -6.57 mg/L; CI -11.47 to -1.67; P = 0.009) and erythrocyte sedimentation rate (ESR) (pooled WMD of -7.94 mm/h; CI -12.65 to -3.22; P = 0.001) levels. In addition, this effect was greater for vitamin D levels at doses greater than 2000 IU, and when follow-up duration was more than 12 weeks.

CONCLUSION

This study showed that vitamin D therapy can have a significant and beneficial effect on 25(OH) D3, calcium, and inflammatory factors in children and adolescents with IBD.

JNK pathway-associated phosphatase illustrates low expression and negative correlations with inflammation, disease activity, and T-helper 17 cells in inflammatory bowel disease children

Background

C‐Jun N‐terminal kinase pathway‐associated phosphatase (JKAP) modulates the T cell receptor and mitogen‐activated protein kinase pathway‐mediated autoimmunity, thus participating in the pathogenesis of autoimmune diseases. This study aimed to explore the clinical implication of JKAP in inflammatory bowel disease (IBD) children.

Methods

C‐Jun N‐terminal kinase pathway‐associated phosphatase, tumor necrosis factor‐α (TNF‐α), interleukin‐23, interferon‐γ (T‐helper 1 secreted cytokine), and interleukin‐17A (T‐helper 17 secreted cytokine) in serum samples from 140 IBD children (including 60 Crohn's disease (CD) children and 80 ulcerative colitis (UC) children) were detected by ELISA. Meanwhile, JKAP from serum samples of 10 healthy controls (HCs) was also detected by ELISA.

Results

C‐Jun N‐terminal kinase pathway‐associated phosphatase was reduced in CD children (median (interquartile range (IQR)): 51.6 (36.8–69.5) pg/ml) and UC children (median (IQR): 57.5 (43.4–78.5) pg/ml) compared with HCs (median (IQR): 101.8 (70.0–143.2) pg/ml) (both p < 0.05). In CD children, JKAP was negatively correlated with C‐reactive protein (CRP) (p = 0.016) and erythrocyte sedimentation rate (ESR) (p = 0.029); while in UC children, JKAP was also negatively correlated with CRP (p = 0.006) and ESR (p = 0.022). Regarding the correlation of JKAP with disease activity, it presented negative correlations with PCDAI (p = 0.001) and PUCAI (p = 0.002). Besides, JKAP was negatively related to TNF‐α (both p < 0.05) but not interleukin‐23 (both p>0.05) in CD and UC children. Additionally, JKAP was not correlated with interferon‐γ in CD or UC children (both p>0.05), while negatively correlated with interleukin‐17A in CD and UC children (both p < 0.05).

Conclusion

C‐Jun N‐terminal kinase pathway‐associated phosphatase shows low expression and negative correlations with inflammation, disease activity, and T‐helper 17 cells in IBD children.

Single-stage restorative proctocolectomy for ulcerative colitis in pediatric patients: a safe alternative

BACKGROUND

Surgical management for refractory ulcerative colitis (UC) has been restorative proctocolectomy (RP) with ileal-pouch-anal-anastomosis (IPAA) done as one to three stages, with safety and effectiveness of a single-stage operation unclear.

METHODS

Pediatric UC patients from 2004 to 2019 who underwent RP/IPAA in the initial operation were retrospectively reviewed. 1-stage operations were matched 1:2 to 2-stage operations using age, duration of disease, and disease severity.

RESULTS

Ninety-nine patients (33 1-stage, 66 2-stage) were identified. The median total operative time was shorter in the 1-stage group (6 h:00 min vs. 7 h:47 min, p = 0.004). Total length of stay was shorter in the 1-stage group (9 vs. 17 days, p = 0.001). Rates of readmission were higher in 2-stage group (30 vs. 9%, p = 0.02). There was no difference in pouch leak rates (p = 1.00). Stricture rates were higher in the 2-stage group (50 vs. 16%, p = 0.005). Functional outcomes including pouchitis (p = 0.13), daily bowel movements (p = 0.37), and incontinence (p = 0.77) were all similar.

CONCLUSIONS

Restorative proctocolectomy with IPAA in children with UC can be performed as a 1- or 2-stage operation with equivalent short-term, long-term, and functional outcomes in similar risk population. Our findings suggest 1-stage RP/IPAA operations without ileostomy are a safe alternative for patients considered for a 2-stage operation.
