The diagnostic efficacy of creatine kinase (CK) isoforms (CK-3 and CK-2) was compared with measurement of CK-2 mass concentrations for the early diagnosis of myocardial infarction (MI). Serial serum samples drawn from 76 patients with confirmed MI and 55 non-MI patients were used for determining CK-2 mass concentrations and the MM3/MM1 (CK-3 isoforms) and MB2/MB1 (CK-2 isoforms) ratios. We comp...

BACKGROUND Serum apoptotic cytokeratine 18 neoepitope M30 (CK-18 M30) and matrix metalloproteinase 2 (MMP-2) have been popular markers for detecting liver fibrosis in recent years. CK-18 is a major intermediate filament protein in liver cells and one of the most prominent substrates of caspases during hepatocyte apoptosis. MMP-2 plays an important role in tissue remodeling and repairing process...

We have studied cytokeratin (CK) expression in two cases of well-differentiated and poorly differentiated squamous cell carcinoma (SCC) arising from hidradenitis suppurativa (HS) (acne inversa). In both cases, type A (infundibular-like keratinized) epithelia were observed. In type A epithelia, CK 1 and 10 expressions were decreased, and CK 14 and 17 were detectable in the whole layers. CK 7, 8,...

Nonalcoholic fatty liver disease (NAFLD) is one of the most common forms of chronic liver diseases worldwide. The prevalence of NAFLD was 15% in the Asian population. In a study, NASH was observed in 42.4% of NAFLD cases in Bangladesh. It is a serious clinical problem because of its worldwide distribution and potential adverse sequel. Cytokeratin-18 fragment is a marker of hepatocyte apoptosis....

UNLABELLED Liver biopsy remains the gold standard for diagnosing nonalcoholic steatohepatitis (NASH). We have recently demonstrated that plasma cytokeratin 18 (CK-18) fragment levels correlate with the magnitude of hepatocyte apoptosis and independently predict the presence of NASH. The goal of this study was to validate the use of this biomarker for NASH diagnosis. The study was an ancillary s...

Background: Hepatocellular carcinoma (HCC) is a common malignancy that occurs secondary to viral hepatitis B and C cirrhosis under the influence of environmental factors. In early stages, clinical diagnosis is often difficult and distinguishing HCC from cirrhosis and other hepatic masses by conventional tests is frequently not feasible. Physicians usually depend on measuring serum alpha-fetopro...

The expression of cytokeratins (CKs) in human lung cancer was studied using chain-specific monoclonal antibodies to CKs 4, 7, 8, 10, 13, 18, and 19. When applied to adenocarcinomas (ACs) of the lung, high levels of CKs 7, 8, 18, and 19 were detected in all tumors, while CK 4 was found in high concentrations in some ACs. CK 10 and 13 were completely absent, or only present in low numbers of cell...

Liver biopsy still remains the gold standard for diagnosing nonalcoholic steatohepatitis (NASH), but with limitations. There is an urgent need to develop noninvasive tests that accurately distinguish NASH from simple steatosis. The purpose of this meta-analysis was to evaluate the diagnostic value of serum biomarkers including cytokeratin 18 (CK-18), fibroblast growth factor 21 (FGF-21), and co...
