Factors Associated with Poor Quality of Life in a Canadian Cohort of Patients with Inflammatory Bowel Disease: A Cross-sectional Study.

BACKGROUND: Health-related quality of life (QoL) is often adversely affected in patients with inflammatory bowel disease (IBD). We aimed to identify factors associated with poor QoL among Canadian patients with IBD in clinical remission. METHODS: We enrolled patients at a single academic tertiary care center with inactive IBD. All eligible patients completed a series of questionnaires that included questions on demographics, disease activity, anxiety, depression and the presence of irritable bowel syndrome (IBS) symptoms. Stool sample for fecal calprotectin (FC) was also collected to assess for subclinical inflammation. The primary outcome measure was QoL assessed by the short inflammatory bowel disease questionnaire (SIBDQ), with planned subgroup comparisons for fatigue, anxiety, depression and IBS symptoms. RESULTS: Ninety-three patients were eligible for inclusion in this study. The median SIBDQ scores were lower in patients with anxiety (P < 0.001), depression (P = 0.004), IBS symptoms (P < 0.001) and fatigue (P = 0.018). Elevated FC in patients in clinical remission did not impact QoL. These findings were consistent on multivariate linear regression. CONCLUSIONS: Anxiety, depression, fatigue and IBS symptoms are all independently associated with lower QoL in patients with inactive IBD. Clinicians are encouraged to screen for these important factors as they may detrimentally impact QoL in IBD patients even in clinical remission.

Ultrasound vs Endoscopy, Surgery, or Pathology for the Diagnosis of Small Bowel Crohn's Disease and its Complications.

BACKGROUND: In patients with inflammatory bowel disease, we strive to achieve mucosal healing, as this has been shown to decrease the risk of disease flares, hospitalization, and surgery. For this reason, we must use objective measures of mucosal healing to inform our clinical decision-making and can no longer rely on patient symptoms alone. Assessment of small bowel Crohn's disease (SBCD) is particularly challenging given its lack of accessibility via standard endoscopic techniques. Ultrasound (US) represents a readily available, cost-effective, minimally invasive, radiation-free alternative for the assessment of small bowel disease. In this study, we performed a systematic review to determine the accuracy of ultrasound in diagnosing SBCD and its complications as compared with endoscopic visualization, surgery, and/or pathology. METHODS: We searched MEDLINE, EMBASE, and CENTRAL. Prospective cohort studies published up to March 2017 were reviewed. References meeting all eligibility criteria were assessed at the full-text level by 2 independent reviewers. Sensitivity and specificity were collected where available. RESULTS: A total of 2817 unique references were identified. Twenty-two studies were included. All studies were at low-moderate risk of bias based on the Quality Assessment of Diagnostic Accuracy Studies criteria. Transabdominal US (TAUS) yielded moderately high sensitivity and specificity for the diagnosis of SBCD and its postoperative recurrence. Detection was more accurate for severe postoperative recurrence. The diagnostic accuracy of US in stricture and abscess detection was high. Contrast enhancement improved the detection of abscess. Diagnostic detection of fistulas was of moderate accuracy. Entero-enteric fistulization and entero-mesenteric fistulization were most clearly identified. CONCLUSIONS: Ultrasound can be used to diagnose SBCD in those with known or suspected Crohn's disease. It can be used to detect postoperative recurrence and can accurately identify abscesses and fistulas, especially with the aid of contrast enhancement.

Twenty-four hour noninvasive ventilation in Duchenne muscular dystrophy: a safe alternative to tracheostomy.

BACKGROUND: Almost all patients with Duchenne muscular dystrophy (DMD) eventually develop respiratory failure. Once 24 h ventilation is required, either due to incomplete effectiveness of nocturnal noninvasive ventilation (NIV) or bulbar weakness, it is common practice to recommend invasive tracheostomy ventilation; however, noninvasive daytime mouthpiece ventilation (MPV) as an addition to nocturnal mask ventilation is also an alternative. METHODS: The authors' experience with 12 DMD patients who used 24 h NIV with mask NIV at night and MPV during daytime hours is reported. RESULTS: The mean (± SD) age and vital capacity (VC) at initiation of nocturnal (only) NIV subjects were 17.8±3.5 years and 0.90±0.40 L (21% predicted), respectively; and, at the time of MPV, 19.8±3.4 years and 0.57 L (13.2% predicted), respectively. In clinical practice, carbon dioxide (CO2) levels were measured using different methods: arterial blood gas analysis, transcutaneous partial pressure of CO2 and, predominantly, by end-tidal CO2. While the results suggested improved CO2 levels, these were not frequently confirmed by arterial blood gas measurement. The mean survival on 24 h NIV has been 5.7 years (range 0.17 to 12 years). Of the 12 patients, two deaths occurred after 3.75 and four years, respectively, on MPV; the remaining patients continue on 24 h NIV (range two months to 12 years; mean 5.3 years; median 3.5 years). CONCLUSIONS: Twenty-four hour NIV should be considered a safe alternative for patients with DMD because its use may obviate the need for tracheostomy in patients with chronic respiratory failure requiring more than nocturnal ventilation alone.
