RESUMEN

OBJECTIVES: To examine the underlying mechanisms that lead growth impairment to occur more commonly in males than females with Crohn's disease (CD). STUDY DESIGN: Children and adolescents with CD were enrolled in a prospective multicenter longitudinal cohort study. Height Z-score difference was computed as height Z-score based on chronological age (height chronological age-Z-score) minus height Z-score based on bone age (height bone age-Z-score) using longitudinal data. Specific serum cytokines were measured, hormone Z-scores were calculated based on bone age (bone age-Z), and their longitudinal associations were examined. RESULTS: There were 122 children with CD (63% male) who completed 594 visits. The mean ± SD chronological age was 11.70 ± 1.79 years. The mean ± SD height chronological age-Z-score was -0.03 ± 0.99 in males and -0.49 ± 0.87 in females. The mean ± SD height bone age-Z-score was 0.23 ± 0.93 in males and 0.37 ± 0.96 in females. The magnitude of the mean height Z-score difference was greater in females (-0.87 ± 0.94) than males (-0.27 ± 0.90; P = .005), indicating growth was better in females than males. The following negative associations were identified: in females, interleukin (IL)-8 (P < .001) and IL-12p70 (P = .035) with gonadotropin-bone age-Z-scores; IL-8 (P = .010), IL-12p70 (P = .020), and interferon-γ (P = .004) with sex hormone-bone age-Z-scores, and IL-8 (P = .044) and interferon-γ (P < .001) with insulin-like growth factor 1-bone age-Z-scores; in males, IL-1 beta (P = .019) and IL-6 (P = .025) with insulin-like growth factor 1-bone age-Z-scores. CONCLUSIONS: Our data suggest that sex-specific molecular pathways lead to growth impairment in children with CD (primarily growth hormone/insulin-like growth factor-1 axis in males and primarily hypothalamic-pituitary-gonadal axis in females). Mapping these sex-specific molecular pathways may help in the development of sex-specific treatment approaches targeting the underlying inflammation characteristic of CD.

RESUMEN

OBJECTIVES: To compare patient-reported outcomes in black/African American patients with white patients participating in IBD Partners Kids & Teens, in order to identify possible racial healthcare disparities in pediatric inflammatory bowel disease (IBD) as future targets for improvement. STUDY DESIGN: This was a cross-sectional analysis comparing patient-reported outcomes in black/African American patients with white patients, aged 9-18 years, with IBD participating in the IBD Partners Kids & Teens cohort from August 2013 to April 2018. Secondary outcomes included number of IBD-related hospitalizations and surgeries, current medication use, and disease activity. RESULTS: We included 401 patients with Crohn's disease (white = 378 [94%]; black/African American = 23 [6%]). For children with Crohn's disease, black/African American patients compared with white patients reported less anxiety (40.7 vs 47.5, P = .001) and fatigue (44.3 vs 48.4, P = .047) despite more frequently reported treatment with biologics (91% vs 61%, P = .006) and antibiotics (17% vs 5%, P = .03) and history of hospitalizations (81% vs 52%, P = .02). CONCLUSIONS: Black/African American children with Crohn's disease were less likely to report anxiety or fatigue than white patients, despite an apparent more severe disease course reflected by greater reported frequency of treatment with biologics and antibiotics and history of hospitalizations.

RESUMEN

We compared the severity of pediatric inflammatory bowel disease in South Asians with Whites in the US. South Asians more commonly presented with poor weight gain, developed fistulas, and received treatment with antibiotics, methotrexate, adalimumab, and steroids. South Asians appear to have a more complicated presentation and course of pediatric inflammatory bowel disease.

RESUMEN

BACKGROUND: Softer endotracheal (ET) tubes are more difficult to navigate in the oropharynx than the stiffer polyvinyl chloride (PVC) tubes during nasotracheal intubation (NTI). Cuff inflation has been used to guide PVC tubes into the laryngeal inlet during blind NTI, but it has not been tested when performing NTI under direct laryngoscopic guidance. We assessed the role of cuff inflation in improving oropharyngeal navigation of 3 ET tubes of varying stiffness during direct laryngoscope-guided NTI. Simultaneously, we also assessed and compared the nasotracheal navigability and incidence of nasal injury with these ET tubes during cuff inflation-supplemented, laryngoscope-guided NTI. METHODS: One hundred sixty-two adults were randomized to undergo NTI with either a conventional PVC (n = 54), wire reinforced (WR; n = 54) or a silicone-tipped WR (SWR; n = 54) ET tube. Ease of insertion of these tubes was assessed during passage from nose into oropharynx, from oropharynx into laryngeal inlet aided by cuff inflation if needed, and from laryngeal inlet into trachea. Nasal morbidity was assessed by a blinded observer. RESULTS: All ET tubes could be inserted into the trachea. Seventy-one of 162 ET tubes could be inserted from the oropharynx into the laryngeal inlet without cuff inflation. Eighty-six of the remaining 91 tubes that did not enter the laryngeal inlet without cuff inflation could be inserted when using the cuff inflation technique. Thus, a total of 157 ET tubes could be inserted into the laryngeal inlet with cuff inflation (95% confidence interval of difference of proportions between total number of tubes passed [157] and those without cuff inflation [71]: 53% [45%-61%]). The remaining 5 tubes had to be inserted with the help of Magill forceps. The incidence of epistaxis was lowest with the SWR tube (difference of proportions [95% confidence interval] SWR versus PVC 27% [8%-45%]; SWR versus WR 20% [1%-38%]; WR versus PVC 7% [-12% to 26%]). CONCLUSIONS: The cuff inflation technique consistently improved the oropharyngeal insertion of the 3 ET tubes of varying stiffness during direct laryngoscope-guided NTI. Supplemented with the cuff inflation technique, the SWR ET tube seems to be better than the PVC and WR ET tubes in terms of complete nasotracheal navigability and less perioperative nasal injury.

RESUMEN

OBJECTIVES: Few clinical predictors are associated with definitive proctocolectomy in children with ulcerative colitis (UC). The purpose of the present study was to identify clinical predictors associated with surgery in children with UC using a disease-specific database. METHODS: Children diagnosed with UC at age <18 years were identified using the Pediatric Inflammatory Bowel Disease Consortium (PediIBDC) database. Demographic and clinical variables from January 1999 to November 2003 were extracted alongside incidence and surgical staging. RESULTS: Review of the PediIBDC database identified 406 children with UC. Approximately half were girls (51%) with an average age at diagnosis of 10.6 ±â€Š4.4 years in both boys and girls. Average follow-up was 6.8 (±4.0) years. Of the 57 (14%) who underwent surgery, median time to surgery was 3.8 (interquartile range 4.9) years after initial diagnosis. Children presenting with weight loss (hazard ratio [HR] 2.55, 99% confidence interval [CI] 1.21-5.35) or serum albumin <3.5 g/dL (HR 6.05, 99% CI 2.15-17.04) at time of diagnosis and children with a first-degree relative with UC (HR 1.81, 99% CI 1.25-2.61) required earlier surgical intervention. Furthermore, children treated with cyclosporine (HR 6.11, 99% CI 3.90-9.57) or tacrolimus (HR 3.66, 99% CI 1.60-8.39) also required earlier surgical management. Other symptoms, laboratory tests, and medical therapies were not predictive for need of surgery. CONCLUSION: Children with UC presenting with hypoalbuminemia, weight loss, a family history of UC, and those treated with calcineurin inhibitors frequently require restorative proctocolectomy for definitive treatment. Early identification and recognition of these factors should be used to shape treatment goals and initiate multidisciplinary care at the time of diagnosis.

RESUMEN

BACKGROUND AND AIMS: The timing of menarche in Crohn's disease (CD) is poorly described. Our objectives were to study age at menarche onset in CD, and factors associated with this. METHODS: We compared the age at menarche of 34 CD patients with that for 545 controls, using data in the National Health and Nutrition Examination Survey (NHANES). RESULTS: Mean chronological age (CA) of CD patients (15.6 years) did not differ from that of the NHANES cohort (15.7 years; P = 0.91). The median CA at menarche (13.9 years) in CD was older than in the NHANES sample (12.0 years) (P < 0.00005). In CD patients, the cumulative incidence of menarche was 10 % at CA 12 years, 51 % at CA 14 years, and 100 % at CA 16 years. Sixty-eight percent reached menarche by bone age (BA) 13.5 years and 100 % by BA greater than 14.0 years. Menarche occurred earliest in South Asians, followed by East Asians, and then Caucasians (P = 0.02). CONCLUSIONS: CA at menarche is delayed in CD compared with the NHANES cohort. BA at menarche in CD is similar to BA at menarche reported for healthy children. CA at menarche in CD differs by race. If menarche has not occurred by BA greater than 14.0 years, endocrinology referral should be considered.

RESUMEN

BACKGROUND: Statural growth impairment is more common in male patients with Crohn's disease (CD). We identified clinical variables associated with height z score differences by sex in children participating in the Growth Study, a prospective multicenter longitudinal study examining sex differences in growth impairment in pediatric CD. METHODS: Patients with CD (female patients with bone age [BA] ≥4 years 2 months and ≤12 years; male patients with BA ≥5 years and ≤14 years at screening) who had completed study visit 1 qualified. The height z score difference was computed as height z score based on chronological age minus height z score based on BA. RESULTS: One hundred thirteen patients with CD (36% female) qualified. The mean chronological age was 12.0 ± 1.8 (SD) years. The magnitude of the mean height z score difference was significantly greater in female patients (-0.9 ± 0.8) than in male patients (-0.5 ± 0.9; P = 0.021). An initial classification of inflammatory bowel disease as CD (P = 0.038) and perianal disease behavior at diagnosis (P = 0.009) were associated with higher standardized height gain with BA progression, and arthralgia at symptom onset (P = 0.016), azathioprine/6-merpcaptopurine (P = 0.041), and probiotics (P ≤ 0.021) were associated with lower standardized height gain with BA progression in female patients. Patient-reported poor growth at symptom onset (P = 0.001), infliximab (P ≤ 0.025), biologics (P ≤ 0.015), methotrexate (P = 0.042), and vitamin D (P ≤ 0.010) were associated with higher standardized height gain with BA progression, and initial classification as CD (P = 0.025) and anorexia (P = 0.005) or mouth sores (P = 0.004) at symptom onset were associated with lower standardized height gain with BA progression in male patients. CONCLUSIONS: Different clinical variables were associated with statural growth in male patients vs female patients, suggesting that sex-specific molecular pathways lead to statural growth impairment in CD.

RESUMEN

BACKGROUND: The small bowel follow-through (SBFT) is a noninvasive imaging modality for evaluating terminal ileum (TI) inflammation. The accuracy of this modality in pediatric patients is not well established. PATIENTS AND METHODS: We retrospectively determined the sensitivity and specificity of SBFT for detecting TI inflammation diagnosed on histology in 93 pediatric patients studied in a single institution. RESULTS: The mean age at the first study was 12.9 years (range 1.1-20.9 years). Forty-five percent were girls. Twenty-five patients (27%) had abnormal TIs on SBFT. Seventeen patients (18%) had TI inflammation diagnosed by biopsy. The sensitivity of SBFT was 59% and the specificity was 80% for detecting TI inflammation diagnosed on histology. Sensitivity and specificity did not change by demographic factors, final diagnoses, presenting symptoms, or laboratory parameters, reflecting the presence of intestinal inflammation. CONCLUSIONS: The sensitivity and specificity of SBFT in pediatric patients were poor and did not vary with demographic factors, final diagnoses, presenting symptoms, or laboratory parameters. Prospective longitudinal studies comparing various imaging modalities (SBFT, magnetic resonance enterography, and capsule endoscopy) are required to determine which is the most effective tool for evaluating pediatric patients for TI inflammation.

RESUMEN

BACKGROUND: Few studies have reported on the surgical outcomes of colectomy in pediatric patients with ulcerative colitis (UC). PATIENTS AND METHODS: We conducted a retrospective chart review of all pediatric patients diagnosed with UC who underwent colectomy at UCSF between 1980 and 2005 to identify early (within 30 days) and later complications of surgery. RESULTS: Complete medical records were available for 31 patients [12.4 +/- 3.3 (range 6-19) years] with UC who underwent colectomy at UCSF Children's Hospital. Total colectomy with ileal pouch anal anastomosis (IPAA) was performed in 21 of the 31 patients (12 without diverting ileostomy). Five of the 31 patients had an initial colectomy with IPAA and J-pouch performed later; 4 had an initial subtotal colectomy for urgent indications. Only one of 31 had IPAA with S-pouch. The median number of early postoperative complications was 1.0; 4 required additional surgery to treat complications. The most common early complications were small intestinal obstruction in 6 (19%) and wound infection in 4 (13%). Preoperative medications included corticosteroids in 25 (81%), 6-mercaptopurine/azathioprine in 10 (32%), and 5-aminosalicylates in 19 (61%). Medication exposure was not related to postoperative complications. Late complications included pouchitis in 12 (39%), anastomotic, anal, or rectal strictures in 5 (16%), and fistulas in 5 (16%); 1 (3%) was subsequently diagnosed as having Crohn disease. CONCLUSIONS: Postcolectomy morbidity is common among pediatric patients with UC. Preoperative medications were not associated with postoperative complications. Investigations to determine preoperative factors affecting surgical outcomes and long-term satisfaction following this surgery in a large pediatric cohort are needed.

RESUMEN

BACKGROUND: Cessation of statural growth occurs with radiographic closure of the growth plates, radiographically defined as bone age (BA) 15 years in females and 17 in males. METHODS: We determined the frequency of continued growth and compared the total height gain beyond the time of expected growth plate closure and the chronological age at achievement of final adult height in Crohn's disease (CD) vs ulcerative colitis (UC) and described height velocity curves in inflammatory bowel disease (IBD) compared with children in the National Health and Nutrition Examination Survey (NHANES). We identified all females older than chronological age (CA) 15 years and males older than CA 17 years with CD or UC in the ImproveCareNow registry who had height documented at ≥3 visits ≥6 months apart. RESULTS: Three thousand seven patients (48% female; 76% CD) qualified. Of these patients, 80% manifested continued growth, more commonly in CD (81%) than UC (75%; P = 0.0002) and in females with CD (83%) than males with CD (79%; P = 0.012). Median height gain was greater in males with CD (1.6 cm) than in males with UC (1.3 cm; P = 0.0004), and in females with CD (1.8 cm) than in females with UC (1.5 cm; P = 0.025). Height velocity curves were shifted to the right in patients with IBD vs NHANES. CONCLUSIONS: Pediatric patients with IBD frequently continue to grow beyond the time of expected growth plate closure. Unexpectedly, a high proportion of patients with UC exhibited continued growth, indicating delayed BA is also common in UC. Growth, a dynamic marker of disease status, requires continued monitoring even after patients transition from pediatric to adult care.

RESUMEN

BACKGROUND: Statural growth impairment is more common in males with Crohn's disease (CD). We assessed sex differences in height Z score differences and bone age (BA) Z scores and characterized age of menarche in a novel contemporary cohort of pediatric CD patients undergoing screening for enrollment in the multicenter longitudinal Growth Study. METHODS: Crohn's disease patients (females with chronological age [CA] 5 years and older and younger than 14 years; males with CA 6 years and older and younger than 16 years) participated in a screening visit for the Growth Study. Height BA-Z scores are height Z scores calculated based on BA. Height CA-Z scores are height Z scores calculated based on CA. The height Z score difference equals height CA-Z score minus height BA-Z score. RESULTS: One hundred seventy-one patients (60% male) qualified for this analysis. Mean CA was 12.2 years. Mean height CA-Z score was -0.4, and mean height BA-Z score was 0.4 in females. Mean height CA-Z score was -0.1, and mean height BA-Z score was 0.2 in males. The absolute value of the mean height Z score difference was significantly greater in females (0.8) than males (0.3; P = 0.005). The mean BA-Z score in females (-1.0) was significantly lower than in males (-0.2; P = 0.002). The median CA at menarche was 13.6 (95% CI, 12.6-14.6) years. CONCLUSIONS: Our screening visit data suggest that standardized height gain is lower in males with skeletal maturation and delayed puberty is common in females in CD. We are investigating these findings in the ongoing Growth Study.

RESUMEN

BACKGROUND: The relationship between the age at diagnosis and disease course is poorly defined in children with Crohn's disease (CD). We examined the presentation and course of disease in patients 0-5 compared to 6-17 yr of age at diagnosis. METHODS: We analyzed uniform data from 989 consecutive CD patients collected between January 2000 and November 2003, and stored in the Pediatric IBD Consortium Registry. The statistical tests account for the length of follow-up of each patient. RESULTS: In total, 98 patients (9.9%) were of 0-5 yr of age at diagnosis. The mean follow-up time was 5.6 +/- 5.0 yr in the younger group and 3.3 +/- 2.8 yr in the older group (P < 0.001). Race/ethnicity differed by the age group (P= 0.015); a larger proportion of the younger group was Asian/Pacific Islander or Hispanic, and a larger proportion of the older group was African American. The initial classification as ulcerative colitis or indeterminate colitis was more common among the 0-5 yr of age group (P < 0.001). The 6-17 yr of age patients presented with more abdominal pain (P < 0.001), weight loss (P= 0.001), or fever (P= 0.07), while the 0-5 yr of age patients presented with more rectal bleeding (P= 0.008). The 6-17 yr of age patients were more likely to be treated with antibiotics (P < 0.001), 6-mercaptopurine/azathioprine (P < 0.001), infliximab (P= 0.001), or corticosteroids (P= 0.0006). The 6-17 yr of age patients had a higher cumulative incidence of treatment with 5-aminosalicylates (P= 0.009) or methotrexate (P= 0.04). The risk for developing an abscess (P= 0.001), a fistula (P= 0.02), a stricture (P= 0.05), or a perianal fissure (P= 0.06) was greater in the 6-17 yr of age patients. CONCLUSIONS: The 6-17 yr of age patients with CD appear to have a more complicated disease course compared to 0-5 yr of age children. The 0-5 yr of age group may represent a unique disease phenotype and benefit from different approaches to management. Long-term prospective studies are required to validate these findings.

RESUMEN

OBJECTIVE: To investigate the effect of human growth hormone (GH) injections on growth velocity in growth-impaired children with Crohn's disease (CD). STUDY DESIGN: Ten children and adolescents (mean age, 12.6 +/- 4.5 years; 6 males) with CD and poor height growth were treated with open-label recombinant GH, 0.043 mg/kg/day administered via subcutaneous injection, for 1 year. Patients were retrospectively matched with untreated patients (3 comparisons per case) by race, age, sex, and baseline height. Primary endpoint was height velocity; secondary endpoints were disease activity, body composition, and bone density determined by dual-energy x-ray absorptiometry scan. RESULTS: Mean height velocity increased by 5.33 +/- 3.40 (mean +/- standard deviation) cm/year in the GH-treated patients during the year of GH treatment, compared with 0.96 +/- 3.52 cm/year in the comparison group (P = .03). Height z-score increased by 0.76 +/- 0.38 in the treated group, compared with 0.16 +/- 0.40 in the comparison group (P < .01), and weight z-score increased by 0.81 +/- 0.89 in the treated group, compared with 0.00 +/- 0.57 in the comparison group (P < .01). Bone density revealed an increase of 0.31 +/- 0.33 in the lumbar spine z-score (P = .03 vs baseline). CONCLUSIONS: GH treatment increases height velocity and may enhance bone mineralization in children with CD. A randomized controlled trial in a large cohort of children is needed to evaluate the ultimate impact of GH treatment.

RESUMEN

AIM: To determine the distribution of anthropometric parameter (AP)-z-scores and characterize associations between medications/serum biomarkers and AP-z-scores in pediatric Crohn's disease (CD). METHODS: CD patients [< chronological age (CA) 21 years] were enrolled in a cross-sectional study. Descriptive statistics were generated for participants' demographic characteristics and key variables of interest. Paired t-tests were used to compare AP-z-scores calculated based on CA (CA z-scores) and bone age (BA) (BA z-scores) for interpretation of AP's. Linear regression was utilized to examine associations between medications and serum biomarkers with AP-z-scores calculated based on CA (n = 82) and BA (n = 49). We reported regression coefficients as well as their corresponding p-values and 95% confidence intervals. RESULTS: Mean CA at the time of the study visit was 15.3 ± 3.5 (SD; range = 4.8-20.7) years. Mean triceps skinfold (P = 0.039), subscapular skinfold (P = 0.002) and mid-arm circumference (MAC) (P = 0.001) BA z-scores were higher than corresponding CA z-scores. Medications were positively associated with subscapular skinfold [adalimumab (P = 0.018) and methotrexate (P = 0.027)] and BMI CA z-scores [adalimumab (P = 0.029)]. Azathioprine/6-mercaptopurine were negatively associated with MAC (P = 0.045), subscapular skinfold (P = 0.014), weight (P = 0.002) and BMI (P = 0.013) CA z-scores. ESR, CRP, and WBC count were negatively associated, while albumin and IGF-1 BA z-scores were positively associated, with specific AP z-scores (P < 0.05). Mean height CA z-scores were higher in females, not males, treated with infliximab (P = 0.038). Hemoglobin (P = 0.018) was positively associated, while platelets (P = 0.005), ESR (P = 0.003) and CRP (P = 0.039) were negatively associated with height CA z-scores in males, not females. CONCLUSION: Our results suggest poor efficacy of thiopurines and a possible sex difference in statural growth response to infliximab in pediatric CD. Prospective longitudinal studies are required.

RESUMEN

Inflammatory bowel disease (IBD) has been increasingly diagnosed in children and adults. Similarly, acute and chronic pancreatitis are increasingly prevalent conditions with potentially devastating consequences. There is a growing body of literature linking these 2 conditions. The purpose of this review is to provide a comprehensive outline of the association between IBD and pancreatitis and to explore their putative pathophysiology. Based on the collective reports, 2 outstanding reasons for pancreatitis in patients with IBD are medications and IBD complications.

RESUMEN

The large protein (L) of the human parainfluenza virus type 3 (HPIV3) is the functional RNA-dependent RNA polymerase, which possesses highly conserved residues QGDNQ located within motif C of domain III comprising the putative polymerase active site. We have characterized the role of the QGDNQ residues as well as the residues flanking this region in the polymerase activity of the L protein by site-directed mutagenesis and examining the polymerase activity of the wild-type and mutant L proteins by an in vivo minigenome replication assay and an in vitro mRNA transcription assay. All mutations in the QGDNQ residues abolished transcription while mutations in the flanking residues gave rise to variable polymerase activities. These observations support the contention that the QGDNQ sequence is absolutely required for the polymerase activity of the HPIV3 RNA-dependent RNA polymerase.

RESUMEN

Eighty-five isolates of Candida recovered from three hundred and fifty diverse clinical sources, viz. respiratory tract (sputum, bronchial washing,bronchoalveolar lavage, tracheal aspirate), blood, urine, high vaginal swab, skin and plastic devices, were studied in detail for their morphological and biochemical characters. Seven species of Candida were identified, viz., C. albicans (45.8%), C. tropicalis (24.7%), C. parapsilosis (10.5%), C. krusei (7.0%), C. kefyr (7.0%), C. guilliermondii (3.5%), and C. glabrata (1.1%). C. albicans was the predominant species isolated from all clinical specimens, except blood from which C. krusei was most frequently (38.4%) recovered. Out of 39 isolates of C. albicans, 26 (66.6%) and 19 (48.7%) exhibited strong proteinase and phospholipase activity respectively. There was a higher prevalence of proteinase producing strains amongst the vaginal and skin isolates than that in urinary and respiratory isolates. Also a greater number of phospholipase producing strains was observed in the vaginal and urinary isolates than that in the respiratory and skin isolates.
