BACKGROUND Neopterin and tissue polypeptide-specific antigen (TPS) have been suggested to be useful in differential diagnosis between pancreatic adenocarcinoma (PA) and chronic pancreatitis (CP). The aim of our study was to compare the clinical usefulness of CA19-9, neopterin and TPS serum levels in patients with PA and CP. METHODS The study included 85 patients with PA, 72 with CP and 50 hea...

Aim: To make proatherogenic/antiatherogenic HDL type criteria using Apolipoprotein A-I (ApoA-I), Paraoxonase-1 (PON-1), Neopterin and HDL-cholesterol levels, which may be useful in clinical practice. Methods: This was a case control study recruiting 52 subjects with Acute Coronary Syndrome (ACS) and 30 control healthy subjects. HDL type was classifi ed into antiatherogenic and proatherogenic ba...

BACKGROUND Infection by hepatitis B virus (HBV) causes complicated biochemical, immunological and histological changes in host immune response against the virus which can be specific or non-specific. Recent attention has focused on neopterin as a marker for the activation of cell mediated immunity. The aim of this study was to define the pattern of neopterin levels in replicative and nonreplica...

The relationship between serum neopterin levels and coronary heart disease (CHD) was investigated. Eighty-six CHD patients were divided into an acute myocardial infarction (AMI) group (N = 21), an unstable angina pectoris (UAP) group (N = 35), and a stable angina pectoris (SAP) group (N = 30), based on coronary angiography (CAG), 30 subjects without CHD served as the control group. Serum neopte...

In an in vitro study, it was found that aspirin might decrease neopterin production and tryptophan degradation. The aim of the present study was to evaluate the possible association between aspirin use and mean neopterin and tryptophan levels in patients with and without a delirium and whether the use of aspirin is associated with a decreased prevalence of delirium. Neopterin and tryptophan lev...

Concentrations of interleukin-6 and neopterin were measured in sera from 44 patients with multiple myeloma. To judge the relative prognostic value of these analyses, other clinical and laboratory variables were concomitantly determined. The patients were followed up to 9 years, and the abilities of all variables to predict outcome were assessed. Both neopterin (P = 0.0008) and interleukin-6 (P ...

Predicting the efficacy of antiviral treatment of hepatitis C virus (HCV) is of importance for both patient well-being and health care expense. The expression of interferon-stimulated genes (IFN-SGs) in the liver was suggested as a marker of response to anti-viral therapy. IFN-SGs encode the guanosine triphosphate cyclohydrolase 1 (GTPCH), a rate-limiting enzyme of pteridines biosynthesis. Neop...

BACKGROUND The serum levels of neopterin, a marker associated with cell-mediated immunity are elevated in chronic kidney disease (CKD). We evaluated serum neopterin levels and investigated its association with markers of inflammation in a cross-section of CKD subjects without known cardiovascular disease. METHODS Serum neopterin levels were measured in 118 patients with stage 3-5 CKD and 41 h...

OBJECTIVE The recovery period in ischemic cerebrovascular disease is sometimes long and complicated. It is thought that a systemic inflammatory response plays an important role in this process. Therefore, promising studies have reported that neopterin and other cytokines serve as indicators of the inflammatory response. The present study investigated the effects of cerebrovascular diseases on p...

To evaluate cellular immune activation in opsoclonus-myoclonus syndrome, we measured the inflammatory marker neopterin in the cerebrospinal fluid of 16 children with opsoclonus-myoclonus and neuroblastoma, 24 children with opsoclonus-myoclonus but no tumor, and 19 age-matched controls. The mean concentration in opsoclonus-myoclonus was 2.3-fold higher than in controls (P = .008). Neopterin was ...
