Neutrophil-to-lymphocyte ratio in inflammatory bowel disease - as a new predictor of disease severity
Background:
The aims of this study were to investigate the utility of neutrophil-to-lymphocyte ratio (NLR) as a simple and readily available predictor for clinical disease activity in inflammatory bowel disease (IBD).
Methods:
Sixty-six patients (22 CD, 44 UC) and 41 healthy controls were enrolled in the study. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels and complete blood count (CBC) were measured. The neutrophil and lymphocyte counts were recorded and NLR was calculated. The patients with active or inactive UC and CD were classified according to the severity of the disease.
Result:
The serum NLR values of active CD patients were significantly higher than those of inactive ones and controls (p = 0.000, p = 0.000, respectively). NLR values of active UC patients were significantly higher than those of inactive ones and controls (p = 0.000, p = 0.000, respectively. The optimum NLR cut-off point for active CD and UC was 3.2 and 3.1.
Conclusion:
This study demonstrates that NLR in subjects with IBD is strongly associated with active disease and correlated with clinical and laboratory indices (Tab. 5, Fig. 2, Ref. 31).

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
