BACKGROUND
Nasal polyposis is principally treated by surgery, which may be combined with administration of topical corticosteroids to postpone or prevent recurrences.
OBJECTIVE
In this study endoscopic sinus surgery and subsequent use of topical corticosteroids (budesonide) for 1 year was
OBJECTIVE
Nasal polyps (NP) are a chronic inflammatory disease of the nasal mucosa; their etiology is suspected to involve oxidative stress. Growth differentiation factor-15 (GDF-15), brain natriuretic peptide (BNP), and ischemia-modified albumin (IMA) are biomarkers used especially in the early
OBJECTIVE
We aim to provide useful evidence on the relationship between the albumin levels and chronic rhinosinusitis with nasal polyp (CRSwNP) and its potential use as an inexpensive, reliable, and independent prognostic marker of CRSwNP.
METHODS
Forty-five patients with CRSwNP and 45 healthy
BACKGROUND
Edema represents a key feature of nasal polyp (NP) disease. Members of the vascular endothelial growth factor (VEGF) family may be involved, but the precise role of VEGF-A, VEGF-B, placental growth factor (PlGF), and their receptors VEGFR1 and VEGFR2 in NP edema formation remains
Morphological studies during the treatment of patients with nasal polyps with beclomethasone dipropionate aerosol for one year showed a trend towards a decrease in the number of eosinophils in nasal smears and falls in the increased concentrations of albumin, IgG and IgE in the nasal secretion. No
Objective: To investigate the role of lymph vessel density (LVD) and microvessel pericyte coverage index (MPI) in the pathogenesis of nasal polyps. Methods: Using immunohistochemistry and immunofluorescence double staining method, the expressions of albumin, D2-40 and CD34-α-SMA in 11 specimens of
OBJECTIVE
To confirm the local production of IgE antibody from the nasal polyp tissue, and to evaluate the difference between atopics and non-atopics, nasal polyp tissues were taken from both 10 atopic and 10 non-atopic subjects. The tissue total IgE (tlgE) level was measured by enzyme-linked
BACKGROUND
There is little evidence on the efficacy of glucocorticoid transnasal nebulization therapy in patients with eosinophilic chronic rhinosinusitis with nasal polyps (CRSwNP).
OBJECTIVE
We sought to evaluate the immunologic and remodeling effects of budesonide transnasal nebulization in
Nasal polyps are characterized by chronic eosinophilic inflammation and often coexist with rhinitis and asthma. Many patients with polyps have no detectable allergy, and it is considered that allergy, at least in many cases, is not relevant to polyp to pathogenesis. To explore the association of
BACKGROUND
Nasal polyps (NPs) are characterized by intense edema or formation of pseudocysts filled with plasma proteins, mainly albumin. However, the mechanisms underlying NP retention of plasma proteins in their submucosa remain unclear.
OBJECTIVE
We hypothesized that formation of a fibrin mesh
Ligneous conjunctivitis (LC) is a rare disease characterized by wood-like pseudomembranes developing on the ocular and extraocular mucosae secondary to plasminogen (PLG) deficiency. In this paper, we report two cases of LC in two sisters of 57 and 62 years of age that presented with recurrent,
Although the etiology of nasal polyposis is still not revealed, insights in the pathogenesis have largely expanded over the last years. Usually nasal polyps occur in adults, are bilateral and are characterized by a manifest tissue eosinophilia. Deposition of plasma-proteins (albumin), potentially
OBJECTIVE
The role of the complement system in nasal polyps (CRSwNP) has so far scarcely been studied. Because nasal polyps are characterized by bacterial colonization, and the complement system is an effective defense mechanism, it might be involved in the pathogenesis of CRSwNP. This study was
OBJECTIVE
Nasal polyposis is a chronic inflammatory disease of the upper airway characterized histologically by the infiltration of inflammatory cells like eosinophils or neutrophils. Several hypotheses have been put forward regarding the underlying mechanisms including chronic infection, aspirin
