We illustrate the proposed procedure by assessing the association between the C-reactive protein and some inflammatory diseases with an electronic medical record study of inflammatory bowel disease performed with the Partners HealthCare electronic medical record database where C-reactive protein was only measured for a small fraction of the patients due to budget constraints.
<b>Background and aims:</b> A multicentre, retrospective, non-interventional, patient chart review study was conducted to investigate deep (DR) and histological remission rates during maintenance therapy with biological agents in inflammatory bowel disease (IBD).<b>Methods:</b> We reviewed clinical, endoscopic, and histological findings, and laboratory markers such as C-reactive protein (CRP) and faecal calprotectin (FC) on average of nine years after the initiation of anti-TNF-therapy.
In a univariate analysis, factors such as the severity of IBD, use of an immunosuppressant or immunosuppressants, high levels of fecal calprotectin, and C-reactive protein or erythrocyte sedimentation rate were individually related to a significantly increased risk of opportunistic infection.
Zinc levels did not correlate with disease activity status in CD or UC patients either.In conclusion, beside CRP and fecal calprotectin, serum 25(OH)D levels, but not serum zinc levels, may be an additional useful and noninvasive marker for characterizing different disease activity status of IBD patients.
Patients with IBD displayed significantly lower sTB levels than controls. sTB levels were negatively associated with C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), fecal calprotectin (FC), and hemoglobin (Hb) levels in patients with IBD.
<b>Introduction:</b> Blood C-reactive protein (CRP) and fecal calprotectin levels are routinely measured as surrogate markers of disease activity in Inflammatory Bowel Disease (IBD), but often do not correlate well with the degree of mucosal inflammation in the intestine as established by endoscopy.
Levels of inflammatory markers, particularly high-sensitivity C-reactive protein, were higher in individuals with versus without a diagnosis of inflammatory bowel disease, when assessed at a random point in time during the disease course.
Variables studied included demographic factors (age, gender, race, BMI, BMI percentiles and family history of IBD), presenting symptoms (blood in stools, nocturnal stools, fever, and extra-intestinal manifestations), phenotypic characteristics (using Montreal classification), and laboratory data [white blood cell (WBC) count, hemoglobin, hematocrit, platelet count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)].
Traditional cardiovascular risk factors, treatment exposure, systemic inflammation (mean serum CRP level greater than or equal to 5 mg/L) and IBD clinical activity were assessed.
In the subgroup of 171 newly diagnosed patients with prospective follow-up data, higher mean C-reactive protein levels over time were demonstrated in those with acute anterior uveitis or IBD compared to those without EAMs or those with psoriasis alone (each P = 0.01).
In univariate analyses, significant correlations were observed between childhood HDL-cholesterol (risk ratio (95% CI) for 1-SD change (0.58 (0.42-0.79)) and CRP concentrations (1.20 (1.01-1.43)) with IBD.
The accuracy of the device (as characterized by the area under the receiver operator characteristics curve) is 89% and 83% for cut-offs of 10ng/mL (for neonatal sepsis and pelvic inflammatory disease) and 30ng/mL (for inflammatory bowel diseases) CRP in 1000-fold diluted blood respectively.
Along with C-reactive protein and erythrocyte sedimentation rate, fecal calprotectin (FC) is the standard test for assessing IBD activity, even though its specificity and accuracy are not optimal and it lacks a validated cutoff.
We investigated FC concentrations in pregnant controls and IBD women, and whether FC correlated with physician global assessment (PGA), C-reactive protein (CRP), and Harvey-Bradshaw Index (HBI)/Simple Clinical Colitis Activity Index (SCCAI) before and after pregnancy, as well as during each trimester.
This was a prospective longitudinal study examining the association between HRQoL (IMPACT III) and symptom scores (Pediatric Crohn Disease Activity Index, abbreviated Pediatric Ulcerative Colitis Activity Index), fecal calprotectin measures and blood analyses (C-reactive protein, erythrocyte sedimentation rate, orosomucoid, albumin, hemoglobin, and vitamin-D) in a cohort of 10- to 17-year-old patients with inflammatory bowel disease.
Outcomes recorded at median 6 months after adjustment included endoscopic remission (Mayo <1, Simple Endoscopic Score for Crohn's Disease <3), C-reactive protein, and inflammatory bowel disease-specific health care utilization.
We reviewed charts of 135 children with inflammatory bowel disease and correlated their ESR and CRP values with disease activity in various encounters during 5 years.
The objective of this study was to evaluate the test characteristics of C-reactive protein (CRP) in identifying low serum infliximab concentrations in patients with IBD.
