The Global Allergy and Asthma European Network (GALEN rhinosinusitis cohort: a large European cross-sectional study of chronic rhinosinusitis patients with and without nasal polyps.

BACKGROUND: Chronic rhinosinusitis (CRS) is a common yet under-recognised chronic inflammatory disease of the nose and paranasal sinuses that is classified according to the presence (CRSwNP) or absence (CRSsNP) of nasal polyps. METHODS: This paper reports the methodology and descriptive results of the Global Allergy and Asthma European Network (GALEN) rhinosinusitis cohort. We established a large CRS cohort within the GALEN consortium (European FP6 research initiative) to identify inflammatory endotypes, the natural disease course, and its impact on health-related quality of life (HRQoL). Detailed information on the impact of CRS on HRQoL, comorbidity incidence, objective disease measures, and medical and surgical treatments were collected. RESULTS: This multicentre cross-sectional case-control study recruited 935 adults (869 eligible for analysis: 237 CRSsNP; 445 CRSwNP; 187 controls [reference group]). Comorbidities such as asthma, allergy, eczema, food allergy, urticaria, and chronic obstructive pulmonary disease were significantly more frequent in CRS patients. Nasal corticosteroids, antibiotics, and oral corticosteroids were the most common treatments. Significantly more CRSwNP patients reported previous sinonasal surgery. CONCLUSIONS: This study provides detailed information that facilitates studying CRS and its main phenotypes. However, patient distribution of this study does not necessarily reflect disease distribution in the general population.

The GALEN rhinosinusitis cohort: chronic rhinosinusitis with nasal polyps affects health-related quality of life.

BACKGROUND: Chronic rhinosinusitis (CRS) significantly affects health-related quality of life (HRQoL). Few multinational observational studies have evaluated the impact of CRS with nasal polyps (CRSwNP) on patients’ HRQoL. This study aimed to assess HRQoL outcomes (including analyses by disease severity and impact of comorbidities and refractory disease) in CRSwNP patients from a large European database. METHODOLOGY: Data were analysed from the Global Allergy and Asthma European Network (GALEN) Rhinosinusitis Cohort, including sociodemographic data, patient-reported disease severity (visual analogue scale), and scores on the 36-Item ShortForm Health Survey (SF-36) questionnaire. Differences in mean SF-36 scores were evaluated between patients with CRSwNP and population norms and between subgroups of interest (disease severity, comorbidity, and refractory disease, defined by a history of sinonasal surgery). RESULTS: Patients with CRSwNP (N = 445) had significantly lower mean SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores vs population norms, demonstrating that CRSwNP negatively affects HRQoL. The presence of comorbidities affected HRQoL, as shown by significant differences in PCS scores in patients with asthma or non-steroidal antiinflammatory drug-exacerbated respiratory disease, compared with patients without asthma. Patients with moderate-to-severe disease had significantly lower PCS scores than patients with mild disease. Severe disease had a significant impact on MCS score. History of surgery had a clinically meaningful negative effect on HRQoL compared with no history of surgery. CONCLUSIONS: CRSwNP patients have significantly lower HRQoL compared with population norms. The impact is greater in patients with greater disease severity, comorbidities, or refractory disease.

Impaired virus replication and decreased innate immune responses to viral infections in nasal epithelial cells from patients with allergic rhinitis.

The aim of this study was to assess the immune response to parainfluenza virus type 3 (PIV3), rhinovirus 1B (RV1B) and intracellular Toll-like receptors (TLR) agonists in nasal epithelial cells (NECs) from patients with allergic rhinitis and healthy controls. NECs were obtained from eight patients with allergic rhinitis (AR) and 11 non-atopic healthy controls (HC) by nasal scraping, grown to confluence and exposed to PIV3, RV1B infection or TLR-3 and TLR-7/8 agonists. Interferon (IFN)-λ1, IFN-α, IFN-ß and regulated on activation, normal T expressed and secreted (RANTES) release into the cell culture supernatants was assessed at 8, 24 and 48 h upon infection or 8 and 24 h after stimulation with poly(I:C) and R848. mRNA levels of IFNs, RANTES, interferon regulatory transcription factor (IRF)3, IRF7 and viral gene copy number were determined using real-time polymerase chain reaction (RT-PCR). PIV3 but not RV1B replication 48 h after infection was significantly lower (P < 0·01) in NECs from AR patients compared to HC. PIV3 infection induced significantly less IFN-λ1 (both protein and mRNA) in NECs from AR compared to HC. IFN-ß mRNA expression and RANTES protein release and mRNA expression tended to be smaller in AR compared HC cells in response to both viruses. Stimulation with TLR-3 agonist [poly (I:C)] induced similar IFN-λ1 and RANTES generation in AR and HC subjects. Viral infections in NECs induced IRF7 expression, which correlated with IFN and RANTES expression. These data suggest that virus proliferation rates and the immune response profile are different in nasal epithelial cells from patients with allergic rhinitis compared to healthy individuals.

Important research questions in allergy and related diseases: 3-chronic rhinosinusitis and nasal polyposis - a GALEN study.

Chronic rhinosinusitis is one of the most common health care challenges, with significant direct medical costs and severe impact on lower airway disease and general health outcomes. The diagnosis of chronic rhinosinusitis (CRS) currently is based on clinical signs, nasal endoscopy and CT scanning, and therapeutic recommendations are focussing on 2 classes of drugs, corticosteroids and antibiotics. A better understanding of the pathogenesis and the factors amplifying mucosal inflammation therefore seems to be crucial for the development of new diagnostic and therapeutic tools. In an effort to extend knowledge in this area, the WP 2.7.2 of the GA(2)LEN network of excellence currently collects data and samples of 1000 CRS patients and 250 control subjects. The main objective of this project is to characterize patients with upper airway disease on the basis of clinical parameters, infectious agents, inflammatory mechanisms and remodeling processes. This collaborative research will result in better knowledge on patient phenotypes, pathomechanisms, and subtypes in chronic rhinosinusitis. This review summarizes the state of the art on chronic rhinosinusitis and nasal polyposis in different aspects of the disease. It defines potential gaps in the current research, and points to future research perspectives and targets.

Histopathological verification of clinical indications to partial inferior turbinectomy.

Surgical treatment in cases where disturbances of the nasal patency causes changes in the nasal inferior turbinates is controversial. The authors performed light- and electron microscopy and morphometric examinations of the mucous membrane of the nasal inferior turbinates obtained after partial inferior turbinectomy in patients with vasomotor and perennial allergic rhinitis and compensation hypertrophy of the nasal inferior turbinate accompanied by nasal deviation of the septum. In specimens obtained from patients with vasomotor rhinitis, a small number of glands and fibrosis of the lamina propria was observed. In specimens obtained from perennial allergic rhinitis patients, plenty of glands and large oedema was observed. In the group with compensatory hypertrophy of the inferior turbinate, normal glands and fibred areas around the vessels were observed. The largest histopathological changes of degeneration and hypertrophy of the nasal mucosa were observed in vasomotor rhinitis patients. Histopathological examination of nasal mucosa slides confirmed the usefulness of a partial inferior turbinectomy, but only in vasomotor rhinitis patients.

Tinnitus suppression by electrical promontory stimulation (EPS) in patients with sensorineural hearing loss.

OBJECTIVE: Almost 10-15% of the population suffer from chronic tinnitus. There are clinical indications that a 'pathological sound' may be induced by any level of the auditory pathways. Theraupeutical difficulties and many hypotheses about tinnitus and places from which they originate might indicate various methods of treatment. Electrostimulation tinnitus suppression was achieved by many authors from 22 (Graham, Hazell) to 87% (Portman). The aim of our study was to define the usefulness of electrostimulation in treatment of persistent noise induced cochlear lesion tinnitus (group I - 43 men) and compare the results with the non noise induced tinnitus group II (68 patients). METHODS: Otolaryngological and audiological examination of the patients was made before and after electrostimulation, and at 90 days. The stimulation system consisted of a prototype tinnitus suppressor, the active platino-iridium needle electrode and silver surface electrode located on the forehead. Transtympanal electrical stimulation was performed using positive polarity direct current. Parameters of electrical impulse were individually different and depended on tinnitus parameters and patients sensation. The current levels ranged from 20 to 600 microA and frequency ranged from 60 to 10000 Hz. Average time of EPS was 60 s. RESULTS: The control examination 90 days after stimulation in group I showed subjective improvement in 18 (41.9%) patients, 22 (51.2%) did not notice any change and tinnitus deteriorated in 3 (6.9%) of the patients. In the comparative group II improvement was occurred in 34 (50%) persons including 2 (17.6%) in whom tinnitus was abolished, in 30 (44.1%) tinnitus was unchanged and 4 (0.6%) became worse. In both groups our method did not have a destructive influence on hearing. Electrical stimulation to relieve tinnitus has been used for nearly 200 years, but it is unclear how electrical stimulation works to suppress tinnitus. CONCLUSION: In our opinion electrical stimulation by using positive DC changes the spontaneous activity of cochlear nerve fibres. According to our results it is suggested that the mechanism of beneficial effects is due to increased microcirculation in part of the auditory pathways. Poorer results in patients with noise induced tinnitus could be explained by greater damage of the cochlea outer hair cells. In our opinion EPS could be a method of treatment for persistent tinnitus in cases which fail to respond to other methods.

[Treatment results of acoustic trauma]. / Wyniki leczenia ostrych urazów akustycznych.

20 patients aged from 18 to 42 treated in the past few years because of acoustic trauma. Together the investigations concerned 24 years. Therapeutic schema comprised intravenous infusion--Sermion (Nicergoline--amp. a 4 mg) or Cavinton (Vinpocetine--amp. a 10 mg) 1 amp.--twice a day for 10 days. The treatment of 60% of the patients started in the first week after the trauma occurred, of 20% in the second week and the remaining 20% later on after 15 days when the trauma took place. The obtained results of treatment both of improvement of hearing (79.2%) and tinnitus (66.6%), support the necessity of treatment of acoustic trauma independently from the time that passed after trauma had occurred. Better results of audiometric improvement of hearing (54.2%) and tinnitus disappearance (50%) were obtained in the patients whose treatment started in the first week after trauma. The improvement of hearing and tinnitus disappearance was more observed in patients after treatment by using Sermion than Cavinton.
