Association between telephone activity and features of patients with inflammatory bowel disease.

ABSTRACT: Telephone communication is common between healthcare providers and patients with inflammatory bowel disease (IBD). We analyzed telephone activity at an IBD care center to identify disease and patient characteristics associated with high levels of telephone activity and determine if call volume could identify individuals at risk for future visits to the emergency department (ED) or hospitalization.We performed a prospective observational study in which we categorized telephone calls received by nursing staff over 2 years at a tertiary care IBD clinic (2475 patients in 2009 and 3118 in 2010). We analyzed data on 21,979 ingoing and outgoing calls in 2009 and 32,667 calls in 2010 and assessed associations between clinical factors and logged telephone encounters, and between patterns of telephone encounters and future visits to the ED or hospitalization.Telephone encounters occurred twice as frequently as office visits; 15% of the patients generated >10 telephone encounters per year and were responsible for half of all telephone encounters. A higher percentage of these high telephone encounter (HTE) patients were female, had Crohn's disease, received steroid treatment, had increased levels of C-reactive protein and rates of erythrocyte sedimentation, had psychiatric comorbidities, and had chronic abdominal pain than patients with lower telephone encounters. The HTE patients were also more frequently seen in the ED or hospitalized over the same time period and in subsequent years. Forty-two percent of patients with >8 telephone encounters within 30 days were seen in the ED or hospitalized within the subsequent 12 months.Based on an analysis of telephone records at an IBD clinic, 15% of patients account for half of all calls. These HTE patients are a heterogeneous group with refractory disease who are likely to visit the ED or be hospitalized.

Project description:BackgroundMyeloid cells, including monocytes, macrophages, microglia, dendritic cells and neutrophils are a part of innate immunity, playing a major role in orchestrating innate and adaptive immune responses. Microglia are the resident myeloid cells of the central nervous system, and many Alzheimer's disease (AD) risk loci are found in or near genes that are highly or sometimes uniquely expressed in myeloid cells. Similarly, inflammatory bowel disease (IBD) loci are also enriched for genes expressed by myeloid cells. However, the extent to which there is overlap between the effects of AD and IBD susceptibility loci in myeloid cells remains poorly described, and the substantial IBD genetic maps may help to accelerate AD research.MethodsHere, we leveraged summary statistics from large-scale genome-wide association studies (GWAS) to investigate the causal effect of IBD (including ulcerative colitis and Crohn's disease) variants on AD and AD endophenotypes. Microglia and monocyte expression Quantitative Trait Locus (eQTLs) were used to examine the functional consequences of IBD and AD risk variants enrichment in two different myeloid cell subtypes.ResultsOur results showed that, while PTK2B is implicated in both diseases and both sets of risk loci are enriched for myeloid genes, AD and IBD susceptibility loci largely implicate distinct sets of genes and pathways. AD loci are significantly more enriched for microglial eQTLs than IBD. We also found that genetically determined IBD is associated with a lower risk of AD, which may driven by a negative effect on the accumulation of neurofibrillary tangles (beta=-1.04, p=0.013). In addition, IBD displayed a significant positive genetic correlation with psychiatric disorders and multiple sclerosis, while AD showed a significant positive genetic correlation with amyotrophic lateral sclerosis.ConclusionTo our knowledge, this is the first study to systematically contrast the genetic association between IBD and AD, our findings highlight a possible genetically protective effect of IBD on AD even if the majority of effects on myeloid cell gene expression by the two sets of disease variants are distinct. Thus, IBD myeloid studies may not help to accelerate AD functional studies, but our observation reinforces the role of myeloid cells in the accumulation of tau proteinopathy and provides a new avenue for discovering a protective factor.
