Nasal polyps (NPs) are non-neoplastic, painless inflammatory lesions of the sino-nasal mucosa. Nasal polyp physiopathology is not yet fully understood. There are many potential etiologies of NP, including chronic infections, allergies, asthma, aspirin sensitivity, anatomical disorders, and genetic causes. The purpose of our study was to immunohistochemically demonstrate the presence of mucin (MUC) receptors in chronic rhinosinusitis (CRS) with nasal polyps and determine the relationships between the presence of these receptors and clinical findings. A total of 59 patients who underwent functional endoscopic sinus surgery due to CRS with NPs were included in the study. Groups with positive and negative MUC receptors were evaluated according to their clinical characteristics. According to the data we have obtained, surgery site quality and low-dose steroid response worsened with MUC5A receptor positivity and there were no significant relationships between MUC1 receptor positivity and clinical findings. According to our results, MUC5A receptor positivity was associated with impaired surgical site quality and a reduced response to low-dose systemic steroids by NPs.

UI MeSH Term Description Entries
D009077 Mucins High molecular weight mucoproteins that protect the surface of EPITHELIAL CELLS by providing a barrier to particulate matter and microorganisms. Membrane-anchored mucins may have additional roles concerned with protein interactions at the cell surface. Mucin
D009298 Nasal Polyps Focal accumulations of EDEMA fluid in the NASAL MUCOSA accompanied by HYPERPLASIA of the associated submucosal connective tissue. Polyps may be NEOPLASMS, foci of INFLAMMATION, degenerative lesions, or malformations. Nasal Polyp,Polyp, Nasal,Polyps, Nasal
D011956 Receptors, Cell Surface Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D001241 Aspirin The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis.

D013256 Steroids A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed) Steroid,Catatoxic Steroids,Steroids, Catatoxic
