The purpose of this study was to characterize pharmacokinetics (PK) of PF-04236921, a novel anti-interleukin-6 monoclonal antibody, and its pharmacokinetic/pharmacodynamic (PK/PD) relationship on serum C-reactive protein (CRP) in healthy volunteers and patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and Crohn's disease (CD).
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.
In longitudinal data collected from 20 UC and Crohn disease (CD) patients (10-17 years old), Mixed Effect Models (MEM) were used to analyze the association between SC, FC, CRP, and symptom scores.
Crohn's disease activity index (CDAI) and Simple Endoscopic Score for Crohn's disease (SES-CD) for Crohn's disease (CD) or Mayo score and ulcerative colitis endoscopic index of severity (UCEIS) for ulcerative colitis (UC), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were used to evaluate the disease activity.
Data on fecal calprotectin, C-reactive protein, and other biomarkers from a population of 124 patients with suspected CD of the small bowel studied by CE and included in a PhD study were used to build a scoring index.
FC value had significant positive correlation with CRP, HBI and leukocyte values when measured at similar timepoints.<b>Conclusions:</b> Elevated level of FC approximately 1 year after the initiation of biological therapy was associated with an increased risk of either surgical procedures, corticosteroid initiation, treatment failure or dose increase (i.e. composite outcome) in patients with CD.
On average, patients with higher albumin, lower fecal calprotectin (UC only), lower C-reactive protein (CD only), and no prior TNF-α antagonist use had a higher probability of remission.
To investigate the association between 18F-FDG (Fluorodeoxyglucose) PET (positron emission tomography)/MRE (magnetic resonance enterography) metrics with the inflammatory biomarkers fecal calprotectin and C-reactive protein (CRP) in patients with Crohn's disease (CD).
Serum DKK-1 level was correlated with levels of ESR (r=0.527, P=0.025), CRP (r=0.502, P=0.034), albumin (r=0.363, P=0.021) and PCDAI (r =0.462, P=0.054) in Crohn disease.
In Crohn's disease, subtherapeutic adalimumab concentrations were associated with higher fecal calprotectin and CRP concentrations compared with therapeutic concentrations.
This study did not report on clinical response, CRP, quality of life or withdrawal due to AEs.One small study (N= 50) compared cannabis oil (15% cannabidiol and 4% THC) to placebo in participants with active CD.
Mucosal healing was defined as absence of mucosal ulcers in Crohn's disease (CD) and Mayo endoscopic score ≤1 for ulcerative colitis (UC).Normal CRP was defined as ≤8 mg/L.
Biomarkers of intestinal inflammation, such as faecal calprotectin and C-reactive protein, have been recommended for monitoring patients with Crohn's disease, but whether their use in treatment decisions improves outcomes is unknown.
We examined negative LNs in relation to the local and systemic immune response, including percentage carcinoma, neutrophil and lymphocyte infiltration, Crohn's-like reaction, neutrophil to lymphocyte ratio, platelets, and C-reactive protein (CRP).
BAE findings showed that FC was more accurate for predicting endoscopic remission in CD than C-reactive protein, albumin, white blood cell count, and platelet count.
