Inflammatory bowel disease: Clinical screening and transition of care

The prevalence and clinical characteristics of Clostridium difficile infection in Saudi patients admitted with inflammatory bowel disease: A case-control study

Background

Inflammatory bowel disease (IBD) patients are at increased risk of Clostridium difficile infection (CDI), causing significant morbidity and mortality. This study examined CDI's prevalence, predisposing factors, and clinical outcomes in Saudi hospitalized IBD patients.

Methods

: A retrospective case-control study was conducted at a tertiary medical city in Riyadh, Saudi Arabia. All Saudi adult patients with IBD, admitted over the preceding four years were identified from the hospital's database. Eligible patients were divided into those with CDI and those without CDI. Binary logistic regression was used to determine the predisposing factors for CDI among admitted IBD patients.

Results

During the study period, 95 patients were admitted with IBD. Crohn's disease (CD) was the predominant type (71.6%), whereas 28.4% of the patients were with ulcerative colitis (UC). Only 16 (16.8%) patients had positive CDI. CDI-positive patients tend to have hypertension and previous use of steroids. Patients with UC tend to have a higher risk of CDI than those with CD. Most patients recovered from the CDI (81.3%) with a median time to CDI clearance of 14 days. Three patients (18.8%) had recurrent CDI; among them, one died.

Conclusion

The prevalence of CDI in Saudi IBD patients is similar to that reported elsewhere. UC, steroid treatment, and hypertension are risk factors for CDI in IBD patients. Recurrence of CDI in IBD patients is common and associated with a poor prognosis.

Clinical manifestations of gastrointestinal diseases in the oral cavity

Aim

In this review, several gastrointestinal diseases that dentists may encounter in practice are highlighted and discussed.

Materials and methods

Using MEDLINE (PubMed), a comprehensive review of gastrointestinal diseases and their oral cavity manifestations was performed.

Results

Many gastrointestinal diseases present with oral symptoms that are detectable by dentists and dental hygienists. Often, oral manifestations of the disease may appear before systemic signs and symptoms. Managing patients with these conditions requires dentists to adjust their treatment and/or involve other health professionals.

Conclusion

Care must be taken when providing periodontal therapy or dental implants to patients suffering gastrointestinal diseases who are at high risk of bleeding, infection, or malnutrition, for example. Also, pharmacological therapy for these patients may need to be customized.

Magnetic resonance imaging findings in patients with initial manifestations of perianal fistulas

BACKGROUND

Crohn's disease (CD) is a serious cause of perianal disease and the incidence is increasing in Saudi Arabia. MR imaging may document specific features that may help to foresee Crohn's disease in patients making an initial presentation.

OBJECTIVE

Present MR imaging findings of perianal fistulas in patients making an initial presentation.

DESIGN

Retrospective, observational.

SETTING

Radiology clinic in in Dhahran.

PATIENTS AND METHODS

All previously undiagnosed and untreated patients who presented for the first time to the outpatient clinics from September 2015-2018 with perianal fistulas were retrospectively evaluated. Previously diagnosed CD patients, post-surgical or intervention cases were excluded. Fistulas were categorized as low or high anal, simple or complex, and were graded per St. James University Hospital Classification. Imaging was interpreted by two experienced readers based on the Van Assche score.

MAIN OUTCOME MEASURES

Fistula features on MR imaging and diagnosis of CD.

SAMPLE SIZE

171 patients.

RESULTS

Of 171 patients, 139 (81.3%) were males with mean age of 37.2 (12.7) years; the 32 females had a mean age of 35.8 (10.6) years. Twenty-one patients (12.3%) had CD. Fourteen (40.4%) patients with complex fistulas had CD in comparison to only 5 (4.8%) simple fistula patients ( P=.0005). More than half of patients with complex and high anal fistulas had CD ( P=.0005). Females were more affected than males ( P=.0005).

CONCLUSION

Complex or high anal fistula on MR imaging may be the initial presentation of CD and warrant further work up to establish the diagnosis.

LIMITATIONS

Retrospective, small sample, single center, and short duration study.

CONFLICT OF INTEREST

None.

Arabic translation and psychometric testing of the self-screening malnutrition universal screening tool in inflammatory bowel disease patients

OBJECTIVES

To translate and validate the malnutrition universal screening tool (MUST) for use in Arabic-speaking outpatients with inflammatory bowel disease (IBD).

METHODS

We translated the MUST into Arabic by using the Brislin back-translation method. This methodological study was performed between August 2016 and November 2017 on 143 outpatients with IBD at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. The patients must completed the self-administered (PSA) Arabic version of the MUST. Then, the health-care practitioners (HCPs) administered the Arabic MUST and performed standard patient clinical assessment. The nutrition risk was defined as low (MUST score=0), medium (MUST score=1), or high (MUST score greater than 1). The chance-corrected proportional agreement between the scores from the PSA and HCP-administered Arabic MUST was evaluated using Cohen's kappa coefficient. Internal consistency was evaluated using Cronbach's alpha statistic.

RESULTS

The overall agreement between the PSA and HCP-administered Arabic MUST was almost perfect (agreement=95.9%, expected agreement=72.4%, kappa=0.85, p less than 0.0001). The calculated Cronbach's alpha statistic for MUST scores in 15/143 (10%) patients was 0.79. The calculated Pearson's correlation coefficient between PSA and HCP-administered MUST scores was 0.93 (p less than 0.0001).

CONCLUSIONS

The PSA and HCP-administered Arabic MUST showed perfect agreement in outpatients with IBD.
