Concentrations of trypsin, elastase and carbohydrate antigen CA 19-9 in serum of cystic fibrosis patients.
CLINICALCHEMISTRY, Vol. 32, No. 5, 1986 913 with either substrate, but the observed activity was 55.7% lower with iralanine-4-nitroanilide, in contrast with what happens in sera of males and nonpregnant women. Evidently, i..-alanine-4-mtroanilide behaves like LCHA in this regard, probably reflecting the relative resistance of these substrates to the action of cystyl-aminopeptidase and perhaps o...
متن کاملRheumatoid factor interference in the determination of carbohydrate antigen 19-9 (CA 19-9).
BACKGROUND Investigation of a 61-year-old Caucasian male suffering from fatigue and weight loss led to the finding of a carbohydrate antigen 19-9 (CA 19-9) concentration of 80 kU/L using an ADVIA Centaur analyser. Determination of CA 19-9 on Vidas, AxSYM and Architect i2000 systems gave normal results. His rheumatoid factor concentration was very high (900 kIU/L) and assay interference was susp...
متن کاملBenign Hydronephrosis and Elevated of Serum Levels of Carbohydrate Antigen CA 19-9: A Case Report
BACKGROUND Carbohydrate tumor-associated antigen (CA 19-9) has been shown to be upregulated in other malignant tumors including gastric, ovarian, hepatocellular, and colorectal carcinoma as well as benign diseases of the biliary track such as pancreatitis, cholangitis, and choledocholithiasis. According to the available literature, in several cases of benign hydronephrosis and in a few cases of...
متن کاملPrognostic relevance of carbohydrate antigen 19-9 levels in patients with advanced biliary tract cancer.
Serum carbohydrate antigen 19-9 (CA 19-9) has been identified as biochemical marker for biliary tract cancer (BTC). The purpose of this study was to evaluate its value as a treatment response marker and its value as a prognostic parameter in patients with unresectable BTC. We analyzed 70 patients with BTC treated with chemotherapy. CA 19-9 levels before and after two treatment courses were anal...
متن کاملThe clinical significance of preoperative serum levels of carbohydrate antigen 19-9 in colorectal cancer
PURPOSE Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) are the most frequently used tumor markers in the clinical setting of colorectal cancer (CRC). This study was designed to investigate the correlation between preoperative serum levels of CA 19-9 (pre-CA 19-9) and the clinicopathologic factors of patients with CRC. METHODS A study was performed on 333 patients with ...
