Abstract
OBJECTIVE Observational studies have shown that vitamin D levels are inversely related to ulcerative colitis activity, yet evidence from population interventions remains inconsistent. We conducted a systematic review and meta-analysis of randomized-controlled trials to clarify the effect of vitamin D on blood markers in patients with ulcerative colitis. METHODS The PubMed, Cochrane Library, Embase, CNKI, VIP, and Wanfang databases were searched for studies published before June 2020. Information was collected regarding serum vitamin D levels, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP), and Ca (calcium), and parathyroid hormone (PTH), and ulcerative colitis disease activity index (UCDAI) research data. RESULTS Seven studies (n = 539) were included in the meta-analysis. Vitamin D supplementation resulted in significant improvements in the serum vitamin D levels (standardized mean difference (SMD) = 0.69, 95% CI (0.36, 1.03), P < 0.001), ESR (weighted mean difference (WMD) = - 1.10, 95% CI (- 1.97, - 0.24), P = 0.01), CRP (SMD = - 0.43, 95% CI (- 0.67, - 0.20), P = 0.0003), and Ca (SMD = 0.92, 95% CI (0.09, 1.74), P = 0.03) but not in other outcomes. According to subgroup analysis, supplementation with vitamin D at a dose of ≥ 300,000 IU/day can improve serum vitamin D levels. Supplementation with a sufficient dose of vitamin D in a short period of time can also improve serum vitamin D levels. According to GRADE method evaluation, the evidence quality was classified as low for the Serum Vitamin D Level and ESR, and very low for the CRP, PTH, Ca, and UCDAI. CONCLUSIONS Compared with placebo control interventions, vitamin D supplementation seemed to be an effective intervention for patients with ulcerative colitis. Different doses of vitamin D and durations of intervention produce different effects. However, due to the limitation of the quality of the included studies, the above conclusions still need to be verified by more high-quality studies and weak clinical recommendations.

Increased Fecal Calprotectin Is Associated with Worse Gastrointestinal Symptoms and Quality of Life Scores in Children with Cystic Fibrosis. J Clin Med 2020; 9:jcm9124080. [PMID: 33348735 PMCID: PMC7766355 DOI: 10.3390/jcm9124080] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 12/11/2020] [Accepted: 12/13/2020] [Indexed: 02/06/2023] Open
Abstract
In cystic fibrosis (CF), cystic fibrosis transmembrane regulator (CFTR) dysfunction leads to digestive disorders that promote intestinal inflammation and dysbiosis enhancing gastrointestinal symptoms. In pancreatic insufficiency CF patients, both intestinal inflammation and dysbiosis, are associated with an increase in the fecal calprotectin (FC) level. However, associations between the FC level, gastrointestinal symptoms, and quality of life (QoL) remain poorly studied. We aimed to assess such associations in pancreatic insufficiency CF children. The FC level was measured in pancreatic insufficiency CF children’s stool samples. Children and their parents completed two questionnaires: The Gastrointestinal Symptoms Scales 3.0-PedsQLTM and the Quality of Life Pediatric Inventory 4.0-PedsQLTM. Lower scores indicated worse symptomatology or QoL. Thirty-seven CF children were included. A FC level above 250 µg/g was associated with worse gastrointestinal symptoms and QoL scores. The FC level was inversely correlated with several gastrointestinal scores assessed by children (i.e., Total, “Heart Burn Reflux”, “Nausea and Vomiting”, and “Gas and Bloating”). Several QoL scores were correlated with gastrointestinal scores. The FC level was weakly associated with clinical parameters. Some gastrointestinal and QoL scores were related to disease severity associated parameters. In CF, the FC level, biomarker previously related to intestinal inflammation and dysbiosis, was associated with worse digestive symptoms and QoL scores.

Abstract
OBJECTIVES Iron deficiency anemia (IDA) is very common in children with inflammatory bowel disease (IBD). While health-related quality of life (HRQL) is a key outcome measure, no long-term studies have evaluated the effect of correction of IDA on HRQL in children with IBD. Our goal was to prospectively study changes in HRQL in iron-deficient children with IBD receiving routine iron supplementation with periodic intravenous iron sucrose (IVIS). METHODS Thirty-eight children with IBD treated with infliximab participated. Hematology and inflammatory markers were assessed before each infliximab treatment. Iron-deficient patients (transferrin saturation below 20% and/or ferritin below 30 ng/mL or 100 ng/mL with normal or elevated C-reactive protein, respectively) received IVIS after each infliximab infusion until iron indices stayed normal for two consecutive measurements. HRQL was assessed with Pediatric Quality of Life Inventory every 4 months. Correlation between changes in mean hemoglobin levels and HRQL scores was analyzed prospectively in 3-month periods over a period exceeding 3 years. RESULTS At enrollment, 27 patients had already been established on infliximab; 11 had not started or completed induction. Mean iron indices and hemoglobin normalized after 3 and 6 month of starting IVIS, respectively. Multiple HRQL parameters significantly improved, regardless of the duration of infliximab treatment at the time of enrollment. There was a statistically significant positive correlation between correction of anemia and improvement in parent-reported emotional and physical HRQL scores. CONCLUSIONS Periodic IVIS resulted in long-term correction of IDA in children with IBD. Correction of IDA contributed to some improvements in HRQL.

Low Insulin-like Growth Factor-1 Influences Fatigue and Quality of Life in Children With Inflammatory Bowel Disease. J Pediatr Gastroenterol Nutr 2018; 67:616-621.

Abstract
OBJECTIVE Fatigue is common among patients with inflammatory bowel disease (IBD). Proinflammatory cytokines are elevated in chronic inflammation and can induce "sickness behaviors," such as fatigue. Chronic inflammatory states also lead to growth hormone resistance, demonstrated by low levels of insulin-like growth factor (IGF-1) and elevated growth hormone. This study evaluated the relationship between IGF-1, proinflammatory cytokine levels, and fatigue in patients with IBD. METHODS In this prospective study children with IBD, ages 10 to 16 years, were recruited from a subspecialty ambulatory clinic. Participants and their parents completed age-appropriate generic and disease-specific health-related quality of life (HRQOL) instruments. Serum samples obtained at the same encounter were analyzed for Th17 cytokine and IGF-1 levels. HRQOL scores were compared to a healthy sample and HRQOL scores and cytokine levels were compared by IGF-1 z score quartiles. RESULTS A total of 67 patients with IBD were recruited, median age of 13.7 years (interquartile range, 11.7-15.3). Forty-eight (72%) had inactive disease based on Physician Global Assessment. Patients with IBD reported lower generic HRQOL (P = 0.0006) and more fatigue (P = 0.0004) than a healthy sample. Patients with IGF-1 z scores in the lowest quartile had significantly lower disease-specific HRQOL (P = 0.01) and more fatigue (P = 0.02) than the remainder of the cohort. Serum interleukin (IL)-10, IL-17A, IL-6, and interferon-γ were significantly higher in patients with IBD with IGF-1 z scores in the lowest quartile (P < 0.05). CONCLUSIONS Children with subclinical IBD experience more fatigue and lower generic HRQOL than healthy children. Lower IGF-1 z scores are associated with more fatigue, and this relationship may be mediated through proinflammatory cytokines.

Abstract
Inflammatory bowel diseases (IBDs) may result from dysregulated mucosal immune responses directed toward the resident intestinal microbiota. This review describes the hallmark immunobiology of Crohn's disease and ulcerative colitis as well as therapeutic targets and mechanisms of action for current, experimental, and future treatments in IBD. Conventional therapies include 5-aminosalicylic acid, glucocorticosteroids, thiopurines, and methotrexate. Since 1997, monoclonal antibodies have gained widespread use. These consist of antibodies directed against pro-inflammatory cytokines such as tumor necrosis factor α, interleukin (IL)-12, and IL-23, or anti-homing antibodies directed against α4β7 integrin. Emerging oral therapies include modulators of intracellular signal transduction such as Janus kinase inhibitors. Vitamin D may help to regulate innate and adaptive immune responses. Modulation of the intestinal microbiota, using live microorganisms (probiotics), substrates for the colonic microbiota (prebiotics), or fecal microbiota transplantation (FMT), is in development. Dietary supplements are in widespread use, but providing evidence for their benefit is challenging. Stem cell treatment and nervous stimulation are promising future treatments.
