Abstract:

Background : Ruptured cerebral aneurysms (ICAs) are the most common non-traumatic cause of subarachnoid hemorrhage (SAH) that is associated with life threatening complications such as Vasospasm, Infarction, and Hydrocephalus (HCP). The active participation of macrophage/monocyte-mediated inflammatory response in the pathogenesis of cerebral aneurysm as labeled with Monocyte ChemoattractantProtein-1 (MCP-1) is suggested. Objective: To measure the serum level of MCP-1 in ruptured CAs in different time intervals . Methods: We measured the serum levels of MCP-1 in SAH patients who had CAs and compared it with that of MCP-1 in two control groups: including patients with SAH without CAs, and the normal population of blood donors. We also measured the MCP-1 levels in patients with CAs one week afterward to evaluate the effect of treatment. Serum level of MCP-1 was measured by a commercial ELISA assay. Results: Mean serum MCP-1 level in patients with SAH and CAs was 188.2168 Pg/ml and 331.3982 Pg/ml in the normal population. There was no statistically significant difference between serum levels of MCP-1 on the first (mean=188.2168 Pg/ml) and 7 th days after SAH onset (mean=171.8450 Pg/ml) (p=0.739). Serum level of MCP-1 increased significantly as Glasgow Coma Scale decreased (p=0.078) and Hunt and Hess score increased (p=0.089). Conclusion: Our results did not show an increasing MCP-1 serum level in patients with aneurysmal SAH. There was a relationship between poor clinical grade and MCP-1 levels in patients with CAs. MCP-1 may be a local inflammatory marker for cerebral aneurysms without systemic manifestation.

Increased levels of serum and gingival crevicular fluid monocyte chemoattractant protein-1 in smokers with periodontitis.

BACKGROUND Smoking alters the host response, including vascular function, neutrophil/monocyte activities, adhesion molecule expression, antibody production, and cytokine and inflammatory mediator release. Monocyte chemoattractant protein-1 (MCP-1) is involved in the activation and recruitment of inflammatory and immune cells to infected sites, thereby mediating a variety of pathophysiologic con...

Serum Monocyte Chemoattractant Protein-1 in Pancreatic Cancer

Background/Aims. Pancreatic ductal adenocarcinoma (PDA) has etiological association with chronic inflammation. Elevated circulating levels of inflammatory mediators, such as monocyte chemoattractant protein-1 (MCP-1), are found in obese individuals. We hypothesized that serum MCP-1 levels are elevated in obese PDA patients. Methods. ELISA was used to analyze MCP-1 serum levels in PDA (n = 62) a...

Urine Monocyte Chemoattractant Protein-1(UMCP-1) as a Biomarker of Renal Involvement in Systemic Lupus Erythematosus

Objective(s)Lupus nephritis (LN) is frequently associated with a poor long-term prognosis. Renal biopsy is the diagnostic method of choice in this condition. Urine biomarkers have been mentioned in the diagnosis of LN. The study,s purpose was to evaluate the performance of urinary monocyte chemoattractant protein 1(UMCP-1) as a biomarker of renal involvement in systemic lupus erythematosus.Mate...

Elevated monocyte chemoattractant protein-1 serum levels in patients at risk for coronary artery disease.

BACKGROUND Monocyte chemoattractant protein-1 (MCP-1) is involved in the recruitment of monocytes into the arterial vessel wall as one of the major events leading to atherosclerotic vascular diseases, such as coronary artery disease (CAD). METHODS AND RESULTS The study group comprised 263 volunteers aged between 18 and 85 years who were admitted to hospital or clinic for scheduled invasive an...
