Elevated serum CXCL10 in patients with Clostridium difficile infection are associated with disease severity.

Summary of "Elevated serum CXCL10 in patients with Clostridium difficile infection are associated with disease severity."

Clostridium difficile infection (CDI) is the primary cause of community- and health care-associated diarrhea. CXCL10, also known as IFN-γ-inducible protein of 10 (IP-10), is involved in various inflammatory diseases, but its role in CDI remains unknown. In this study, We determined the serum concentration of CXCL10 in 80 CDI patients and 76 sex & age-matched diarrhea patients by enzyme-linked immunosorbent assay (ELISA) and analyzed the correlation between CXCL10 levels and CDI disease severity parameters. Besides, we also measured the level of other cytokines and/or chemokines in CDI patients, such as IL-1β, IL-6, TNF-α and CXCL9. We found that serum CXCL10 in CDI patients was significantly higher compared with those in non-C. difficile diarrhea patients, especially in the moderate disease. Elevated serum CXCL10 correlated positively and significantly with severity score index (SSI) score in all CDI patients. CXCL10 levels were also positively correlated with WBC count, creatinine and inflammatory cytokines including, IL-1β, IL-6 and CXCL9, but negatively correlated with albumin. Furthermore, serum CXCL10 concentration could be significantly decreased after effective treatment of CDI. Therefore, the above results suggest that the up-regulated release of CXCL10 is important in the immunopathogenesis of CDI, and may be served as a potential alternative biomarker for the monitoring of CDI disease severity and therapeutic efficacy.

Medical and Biotech [MESH] Definitions

A common inhabitant of the colon flora in human infants and sometimes in adults. It produces a toxin that causes pseudomembranous enterocolitis (ENTEROCOLITIS, PSEUDOMEMBRANOUS) in patients receiving antibiotic therapy.

An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.

An acute inflammation of the INTESTINAL MUCOSA that is characterized by the presence of pseudomembranes or plaques in the SMALL INTESTINE (pseudomembranous enteritis) and the LARGE INTESTINE (pseudomembranous colitis). It is commonly associated with antibiotic therapy and CLOSTRIDIUM DIFFICILE colonization.

The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
