1000th Tweet: GI Symptoms Preceding IBD Diagnosis

Another milestone for this blog: since 2012, the blog has been publicized on twitter; this is the 1000th tweet. It is also 1314th blog post over nearly 4 years.

A recent study (H Singh et al. Clin Gastroenterol Hepatol 2015; 13: 1302-09) indicates that children with inflammatory bowel disease (IBD) were more likely to have gastrointestinal symptoms in each of the 4 years before the diagnosis of IBD than children without IBD.

In this study, the researchers identified all children with IBD from a population-based Manitoba database; Manitoba had a population of 1.27 million in 2012.  651 children were matched with 5950 controls without IBD.  The study’s Table 1 & 2 indicates that children with IBD had increased clinic visits prior to diagnosis:

  • 54-66 months prior: standardized rate ratio for number of ambulatory visits 1.15; & for ≥1 visit due to GI symptoms odds ratio 1.44
  • 42-54 months prior: standardized rate ratio for number of ambulatory visits  1.22; & for ≥1 visit due to GI symptoms odds ratio 2.05
  • 30-42 months prior: standardized rate ratiofor number of ambulatory visits 1.19; & for ≥1 visit due to GI symptoms odds ratio 2.16
  • 18-30 months prior: standardized rate ratio for number of ambulatory visits 1.23; & for ≥1 visit due to GI symptoms odds ratio 2.93
  • 6-18 months prior: standardized rate ratio for number of ambulatory visits  1.15; & for ≥1 visit due to GI symptoms odds ratio 5.23

There was not a clear trend in increased symptoms between those who developed Crohn’s disease compared with Ulcerative Colitis. In addition, the study noted a trend towards decreased colectomy and resective surgery in Crohn’s in the time period 2002-2010 compared with 1987-2001.  One limitation of this study is the few number of pediatric gastroenterologists in Manitoba (only 1 before 2003); the lack of pediatric gastroenterology availability could impact timely diagnosis.

My take: This data shows that GI symptoms still predate diagnosis in many children and indicate a potential for diagnosis delay. The authors note that noninvasive tools like stool calprotectin have not been widely adopted (at least in Manitoba) and could be helpful in reducing diagnostic delays.
