Chronic Rhinosinusitis: Biochemical Markers and Biofilm

2014-07-23 21:09:52 | BioPortfolio

Summary

The investigators will conduct a descriptive, prospective, three-armed study concerning the pathophysiology of chronic rhinosinusitis.

In one part of the study the investigators want to investigate the presence of biofilm in patients with chronic rhinosinusitis both with and without nasal polyps compared with a control group of subjects without chronic rhinosinusitis. The investigators will also compare quality of life in the three groups and correlate disease severity in biofilm patients versus patients where biofilm was not present.

The hypothesis here is that biofilm patients suffers a more severe disease.

In the other arm of the study the investigators will compare the presence of different biochemical compounds in the three study groups. The investigators specifically want to investigate matrix metalloproteases and apoptosis-inhibitors with immunohistochemistry. The investigators may also add other compounds to our test-battery if interesting candidates surface in the literature during the inclusion period.

The purpose of this part of the study is to investigate candidates for the development of nasal polyposis.

The investigators plan to include 100 patients suffering from chronic rhinosinusitis with nasal polyps, and 100 patients with chronic rhinosinusitis without nasal polyps and 30 control subjects.

Medical and Biotech [MESH] Definitions

A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show larger-than-normal band of subepithelial COLLAGEN.

A subtype of MICROSCOPIC COLITIS, characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. Microscopic examination of biopsy samples taken from the COLON show infiltration of LYMPHOCYTES in the superficial EPITHELIUM and the underlying connective tissue (lamina propria).

Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.

A condition characterized by chronic watery DIARRHEA of unknown origin, a normal COLONOSCOPY but abnormal histopathology on BIOPSY. This syndrome was first described in 1980 by Read and associates. Subtypes include COLLAGENOUS COLITIS and LYMPHOCYTIC COLITIS. Both have similar clinical symptoms and are distinguishable only by histology.

A mitochondrial disorder featuring the triad of chronic progressive EXTERNAL OPHTHALMOPLEGIA, cardiomyopathy (CARDIOMYOPATHIES) with conduction block (HEART BLOCK), and RETINITIS PIGMENTOSA. Disease onset is in the first or second decade. Elevated CSF protein, sensorineural deafness, seizures, and pyramidal signs may also be present. Ragged-red fibers are found on muscle biopsy.
