Frequent Occurrence of Perianal Disease and Granuloma Formation in Patients with Crohn's Disease and Coexistent Orofacial Granulomatosis.

BACKGROUND: Orofacial granulomatosis (OFG) is an inflammatory disorder of the perioral region and oral cavity. Crohn's disease (CD) in conjunction with OFG (CD-OFG), has been suggested to constitute a phenotype of CD with distinct features at diagnosis. AIMS: The aim of this project was to investigate whether the distinct phenotypic features of CD-OFG persist in the years following the initial diagnosis of CD. METHODS: Clinical data were extracted from medical records covering the first 5 years post-diagnosis for a cohort of patients with CD-OFG, and were compared to those of references with CD without OFG. RESULTS: The clinical characteristics of our cohort of patients with CD-OFG (N = 25) were evaluated in comparison to references with CD without OFG (ratio 1:2). Five years post-diagnosis, more patients with CD-OFG had a phenotype with perianal disease (cumulative incidence: 16/25, 64% vs 13/50, 26%, P = 0.002) and intestinal granulomas (cumulative incidence: 22/25, 88% vs 24/50, 48%, P = 0.0009) than patients in the CD reference group. The patients with CD-OFG were also more likely to have undergone perianal surgery (12/25, 48% vs 4/50, 8%, P = 0.0002). At the end of the observation period, more of the patients with CD-OFG were receiving combination therapy, i.e., immunomodulators and tumor necrosis factor antagonists, than those in the CD reference group (9/25, 36% vs 5/50, 10%, P = 0.01). CONCLUSION: The results support the notion that CD in conjunction with OFG represents a specific phenotype of CD that is characterized by frequent perianal disease, pronounced intestinal granuloma formation and a need for extensive therapy.

Young Adult Male Patients With Childhood-onset IBD Have Increased Risks of Compromised Cortical and Trabecular Bone Microstructures.

BACKGROUND: Young adults with childhood-onset inflammatory bowel disease (IBD) have increased risks of low areal bone mineral density and low skeletal muscle mass. Volumetric BMD (vBMD), bone geometry and microstructures, in addition to possible associations with skeletal muscle index (SMI) and physical exercise have been scarcely studied in this patient group. PATIENTS AND METHODS: In total, 49 young adult male patients with childhood-onset IBD and 245 age- and height-matched young adult male controls were scanned with high-resolution peripheral quantitative computed tomography. Bone geometry, vBMD, and bone microstructures were calculated as median values and compared between the patients and controls. Multivariable linear regression analyses were performed to determine the independent associations among IBD diagnosis, SMI (kg/m2), and physical exercise. RESULTS: The group of young adult patients had, in comparison with the controls, significantly smaller median cortical area (126.1 mm2 vs151.1 mm2, P < .001), lower median total vBMD (296.7 mg/cm3 vs 336.7 mg/cm3, P < .001), and lower median cortical vBMD (854.4 mg/cm3 vs 878.5 mg/cm3, P < .001). Furthermore, the patients compared with the controls had lower median trabecular volume fraction (16.8% vs 18.2%, P < .001) and thinner median trabeculae (0.084 mm vs 0.089 mm, P < .001). The differences between the patients with IBD and controls persisted in multivariable analyses that included adjustments for SMI and physical exercise. CONCLUSIONS: Young adult men with childhood-onset IBD are at increased risk of having reduced bone quality in both the cortical and trabecular bone structures compared with normative matched controls.

Young adult men with childhood-onset IBD appear to have deficits in both cortical and trabecular bone microstructures, measured with high resolution peripheral computed tomography, compared with age- and height-matched young adult male controls.

Dravet syndrome in children-A population-based study.

OBJECTIVE: The aim was to describe age at diagnosis, cumulative incidence, SCN1A variants, mortality, seizure types and treatments in children with Dravet Syndrome (DS) in Sweden. METHODS: Children diagnosed with DS, born between January 1st 2000 and December 31st 2018 were included in a population-based study. Clinical data, frequency of seizure types and treatments were collected from caregivers and medical records in 42 children. Age at diagnosis, cumulative incidence and treatment were compared between children born in Sweden 2000-2009 and 2010-2018. RESULTS: We identified 55 children with DS, 53 were born in Sweden. Three children had died of definite, probable, or possible sudden unexpected death in epilepsy, one of acute anoxic brain injury and three of pneumonia or pneumonitis. Median age at death was 4.7 (range 3.3-11) years. In 49/53 children with known SCN1A status, a pathogenic/likely pathogenic variant of SCN1A was detected. In two a SCN1A variant of unknown significance was found. For children born in Sweden 2010-2018, median age at DS diagnosis was lower (1.6 vs 4.5 years, p = 0.001) and cumulative incidence higher (1/33,000 vs 1/46,000 live-born children, p = 0.03), compared to children born in 2000-2009. The most common seizure types were focal to bilateral tonic clonic (n = 41/42) and myoclonic (n = 35/42). Tonic seizures were reported in 25/42 children. Sodium-channel inhibitors had been used in 9/24 children born in 2010-2018 and 17/18 children born in 2000-2009 (p = 0.001). SIGNIFICANCE: A SCN1A variant that could explain the syndrome was found in over 90% of children. Tonic seizures seem to be more frequent than earlier described. Median age at diagnosis was lower, cumulative incidence higher and use of contra-indicated sodium-channel inhibitors less common for children born in 2010-2018 compared with children born in 2000-2009. This could indicate an increased awareness of DS.

Physical exercise is associated with beneficial bone mineral density and body composition in young adults with childhood-onset inflammatory bowel disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) have an increased risk of compromised bone mineral density (BMD) and body composition. There are limited data on the physical exercise (PE) habits of patients with childhood-onset IBD and on the associations between PE and BMD and body composition. PATIENTS AND METHODS: In total, 72 young adults with childhood-onset IBD and 1341 normative young adult controls answered questionnaires regarding PE [hours/week (h/w)] in the last 12 months. BMD and body composition were measured with dual x-ray absorptiometry (DXA) and presented as age- and gender-adjusted Z-scores for BMD, skeletal muscle index (SMI, the weight of lean mass in arms and legs/m2), and percentage body fat (Fat %). RESULTS: A total of 41 (57%) patients with IBD engaged in PE during the previous 12 months, as compared to 913 (68%) of the controls (p = .053). Sedentary patients had significantly lower median BMD, SMI, and Fat % Z-scores than the controls with corresponding PE habits (all p < .05). In contrast, highly active (>4 h/week) patients had total body BMD, SMI, and Fat % in the same range as the controls with corresponding PE levels (p = .151, p = .992, and p = .189, respectively), albeit with lower BMDs in the spine (p = .007) and femoral neck (p = .015). Using multiple regression analyses, a diagnosis of childhood-onset IBD was independently associated with inferior BMD and body composition, regardless of the amount of PE. CONCLUSION: Physical exercise is associated with beneficial bone mineral density and body composition in patients with IBD despite the negative effects of the disease.

Altered body composition profiles in young adults with childhood-onset inflammatory bowel disease.

Background: Patients with inflammatory bowel disease (IBD) often develop alterations in body composition in terms of their proportions of lean mass and fat mass, as well as reduced bone mineral density (BMD). However, there are limited data on the skeletal muscle index (SMI) and percentage fat (fat %) for young adults with childhood-onset IBD. Our aim was to investigate the body compositions of these patients, with the focus on SMI and fat %.Methods: Body composition was estimated by dual x-ray absorptiometry for 94 young adults with childhood-onset IBD aged 18-27 years, 65 of whom had ulcerative colitis. The Z-scores for SMI, fat %, and BMD were calculated using the normative data from 1,289 individuals with corresponding age. Based on the SMI and fat % Z-scores, each patient was classified as having a body composition profile that was: (i) normal; (ii) obese (fat % Z-score >1); (iii) myopenic (SMI Z-score < -1); or (iv) myopenic-obese.Results: A higher proportion of young adults with childhood-onset IBD had a body composition profile classified as myopenic (24%) or myopenic-obese (9%), as compared to the controls (myopenic [16%, p = .016]; myopenic-obese [2%, p = .002]). Patients with the myopenic or myopenic-obese profile had significantly lower total body BMD Z-scores (-1.3 ± 0.7 and -1.4 ± 0.9, respectively) than patients with the normal profile (-0.2 ± 1.1; p < .001 and p = .004, respectively). Diagnosis of IBD in childhood represented an additional risk for low BMD, regardless of SMI Z-score.Conclusion: Young adults with childhood-onset IBD have a high risk for having altered body composition traits.SummaryYoung adults with childhood-onset IBD carry a high risk for altered body composition traits. The myopenic and myopenic-obese body composition profiles were more frequently observed in patients with IBD than controls, and these profiles were strongly associated with low BMD.

Bone Mass Development from Childhood into Young Adulthood in Patients with Childhood-onset Inflammatory Bowel Disease.

BACKGROUND: Children who have inflammatory bowel disease (IBD) have increased risk of low bone mineral density (BMD). There is a scarcity of information on BMD development through puberty and into young adulthood in patients with childhood-onset IBD. METHODS: We conducted a prospective longitudinal study of BMD in patients with childhood-onset IBD. In total, 74 children with IBD were followed into young adulthood, with a mean follow-up of 8.4 years. The BMD was assessed longitudinally using dual-energy X-ray absorptiometry of the lumbar spine, total hip and whole body, and related to anthropometric measures. RESULTS: Young adult male patients with IBD had lower mean BMD Z-scores for the lumbar spine at -0.8 (±1.1 SD) and total hip at -0.5 (±0.9 SD), as compared to standard references. In young female patients, the BMD Z-scores were within the normal range at all 3 measured sites as compared to the standard references. There were no significant differences in the BMD Z-scores between patients with Crohn's disease and patients with ulcerative colitis. The female and male patients showed significantly improved mean lumbar spine BMD Z-scores during follow-up into young adulthood, indicating that bone accumulation in the lumbar spine continues beyond the expected age for achieving peak bone mass. CONCLUSIONS: Male patients with childhood-onset IBD seem to have an increased risk of compromised BMD in young adulthood. Both female and male patients with IBD seem to increase their BMD beyond the age for expected peak bone mass (see Video abstract, Supplemental Digital Content 1, http://links.lww.com/IBD/B648).

Does Crohn's Disease with Concomitant Orofacial Granulomatosis Represent a Distinctive Disease Subtype?

BACKGROUND: Although orofacial granulomatosis (OFG) may present as a separate clinical entity, it often seems in conjunction with various systemic diseases, of which Crohn's disease (CD) is one of the most common. The aim of this study was to investigate whether CD with concomitant OFG represents a distinctive disease subtype. METHODS: Twenty-one patients with CD and concomitant OFG (CD+OFG group) were included in the study. As the reference group, a cohort of 39 patients with CD but without OFG (CD-R group) was used. Demographic data and clinical characteristics were recorded at the time of diagnosis. The 2 groups were compared using multivariate analyses. RESULTS: The percentage of patients with intestinal inflammation in the upper gastrointestinal tract was significantly higher in the CD+OFG group, as compared with the CD-R group (81% versus 33%; P < 0.001). Furthermore, ileocolonic inflammation was significantly more common in the CD+OFG patients (81% versus 46%; P = 0.013). In addition, perianal disease was more frequently observed in the CD+OFG group (48% versus 18%; P = 0.033). Significantly more patients showed evidence of granulomas in the primary endoscopy in the CD+OFG group than in the CD-R group (81% versus 38%; P = 0.003). CONCLUSION: The data from this study suggest that the presence of CD in conjunction with OFG represents a distinctive subphenotype of CD that is characterized by extensive inflammation, perianal disease, and pronounced granuloma formation in the intestine.

Systemic lupus erythematosus (SLE) is an uncommon disease in children and adolescents but far from being unknown. The disease's symptoms are often non-specific and vague at first and clinicians must suspect SLE without the more specific symptoms. Treatment should be initiated as soon as possible to delay or prevent serious complications. This case demonstrates the history of a young boy who needed medical attention at the Children's Hospital of Iceland because of joint pain, swollen lymph nodes and fatigue. The epidemiology, diagnostic criteria, treatment and prognosis of children diagnosed with SLE are reviewed.
