It leads to disabling gastrointestinal symptoms, low quality of life, and a significant burden for healthcare utilization and associated costs. Therefore, non-invasive biomarkers are needed for early diagnosis and follow up to avoid the complications of invasive diagnostic procedures. Calgranulin C is a calcium binding protein with proinflammatory properties. The aim of this study was to evaluate the role of serum calgranulin C as a non-invasive biomarker for diagnosis and prediction of activity in comparison to different biomarkers and endoscopic activity scores in inflammatory bowel disease. The study included 80 inflammatory bowel disease patients (50 Ulcerative colitis and 30 Chron's patients) and 20 normal controls. Complete blood picture, C-reactive protein, erythrocyte sedimentation rate, fecal calprotectin and serum calgranulin C were measured. Colonoscopies with histopathological examination were done and different activity scoring systems assessed. Among ulcerative colitis group, serum calgranulin C was statistically significantly higher in comparison to control group [723.640±529.055 ng/ml versus 80.850±24.416 ng/ml]. Depending on the American college of gastroenterology ulcerative colitis activity index, fecal calprotectin and serum calgranulin C were statistically significantly higher among moderate to severe ulcerative colitis than those with mild activity and those in remission (p < 0.001, for both). Regarding Crohn's disease group, serum calgranulin C was statistically significantly higher in comparison to control group [759.233±797.963 ng/ml versus 80.850±24.416 ng/mL]. Depending on Crohn's disease activity index, both serum calgranulin C and fecal calprotectin were statistically significantly higher among active disease than those in remission (p < 0.001, for both). In conclusion, serum calgranulin C could be used as a non-invasive marker to predict activity and severity and to ensure remission among inflammatory bowel disease patients.</p>","PeriodicalId":39724,"journal":{"name":"The Egyptian journal of immunology / Egyptian Association of Immunologists","volume":"31 3","pages":"81-94"},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141591555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study included 50 PsA patients and 30 controls. All subjects underwent medical history, musculoskeletal examination, hand and wrist joints ultrasound, and laboratory assessment. The mean age of patients was 41.04±11.8 years with female: male ratio of 3:2, and the median duration of arthritis 2 years (1-4 years) and DAPSA 25 years (3-84 years). The most common finding in patients by ultrasound was synovial hypertrophy in wrist joint (32%) followed by hand joints (28%). Patients' serum calprotectin level was significantly higher (174.2 ng/ml; ranged 127.5-282.6 ng/ml) than controls 41.4 ng/ml; ranged 19.9-59.8 ng/ml) (p < 0.001). Serum calprotectin predicted the occurrence of PsA at cutoff >106.4 ng/ml (with sensitivity 98%, and specificity 86.6%; p=0.001) and predicted synovial hypertrophy in hand joints at cutoff >258.9 ng/ml (with sensitivity 71%, and specificity 83%). There was a significant relation between serum calprotectin with synovial hypertrophy (p=0.004), osteophytes (p < 0.0001), nail affection (p=0.03) and erosions (p=0.01).
