The effect of nasal douching by hypertonic 2.3 per cent sea water with algae extracts on the concentration of epidermal growth factor, transforming growth factor-α and interleukin-8 in nasal secretions of patients with nasal polyposis following endoscopic surgical treatment

OBJECTIVE

To investigate epidermal growth factor, transforming growth factor-α and interleukin-8 production in nasal mucosa irrigated with hypertonic 2.3 per cent solution with algae extracts, in comparison to 0.9 per cent NaCl during the first two weeks after surgery for nasal polyposis, in relation to symptoms and local findings.

METHODS

This prospective study included 20 nasal polyposis patients postoperatively irrigated with hypertonic solution and 20 nasal polyposis patients postoperatively irrigated with isotonic solution. We evaluated nasal symptom score, endoscopic score and mediator levels in nasal secretions before and after irrigation.

RESULTS

Following treatment, nasal symptom score and endoscopic score were significantly lower in the hypertonic solution group (p = 0.023; p < 0.001, respectively). The increase in the epidermal growth factor and the decrease in the transforming growth factor-α and interleukin-8 concentration were higher in the hypertonic group (p < 0.001 for all mediators).

CONCLUSION

Irrigation with a hypertonic solution was found to be more effective than an isotonic solution in nasal mucosa reparation.

Inflammatory mediators in nasal secretions of patients with nasal polyposis with and without aspirin sensitivity

BACKGROUND

The aim of this cross-sectional study was to compare the levels of inflammatory mediators in nasal secretions in patients with aspirin-exacerbated respiratory disease (AERD) and in those with nasal polyposis (NP) without aspirin-sensitivity and to correlate nasal fluid mediator concentrations with clinical parameters of the disease.

METHODS

A total of 30 patients with AERD, 30 chronic rhinosinusitis (CRS) with NP patients without aspirin sensitivity (CRSwNP), and 30 control subjects without inflammation of the nasal mucosa (C), selected for surgical treatment entered the study. The total nasal symptom score (TNSS), endoscopic score (ES), and Lund-Mackay score (LMS), were evaluated. The concentrations of eosinophil cationic protein (ECP), tryptase, heat shock protein 70 (HSP70), substance P and Clara cell protein 16 (CC16) were determined in nasal secretions.

RESULTS

Higher concentrations of ECP, tryptase, and HSP70 were measured in the AERD patients than in the CRSwNP patients and the C group (p < .001; p < .001, respectively for all mediators). However, levels of CC16 were higher in the C group than in the AERD and CRSwNP groups (p < .001; p < .001, respectively). A positive correlation between the TNSS and CC16 and a negative one between CC16 and tryptase levels were found in the C group. The CRSwNP group showed positive correlations between ECP, HSP70, and tryptase and negative correlations between substance P, ES, and LMS, as well as between CC16 and tryptase levels. In the AERD group, we found a positive correlation between HSP70 and ECP levels and a negative correlation between the TNSS and CC16 concentration.

CONCLUSION

The obtained results indicate the increased production of mediators of eosinophil and mast cell function, and the decreased production of biomarker of respiratory epithelial function in AERD patients. Clinical and biochemical parameters correlate in different ways in the AERD and CRSwNP patients.

Simultaneous Nasal Septal Schneiderian Papilloma and Respiratory Epithelial Adenomatoid Hamartoma

Schneiderian papilloma is typically found on the lateral nasal wall, but, in rare cases, can be located at the mucosa of the nasal septum. Respiratory epithelial adenomatoid hamartoma (REAH) is rare, non-neoplastic lesion characterized by an abnormal proliferation of glandular part of the respiratory nasal mucosa. We present a case of a 42-year-old man with five-year history of bilateral nasal obstruction, rhinorrhea, epistaxis, and hyposmia. On endoscopic examination, we found lobulated, yellowish-pink soft tissue masses on both sides of the nasal septum. The results of histopathological analyses showed the characteristics of Schneiderian papilloma in the lesion excised from the right and REAH in the lesion excised from the left side of the nasal cavity. To our knowledge, cases of simultaneous presentation of Schneiderian papilloma and REAH on opposite sides of the nasal septum have not been published so far. An appropriate cooperation of rhinologist and pathologist allows for a correct diagnosis of these rare and unusual lesions.

Effects of Pelargonium sidoides extract on chemokine levels in nasal secretions of patients with non-purulent acute rhinosinusitis

Objective

Previous investigations suggest the use of extract from the roots of Pelargonium sidoides (EPs 7630) for improvement of the symptoms of uncomplicated upper airway inflammations, due to its antimicrobial and immunomodulatory actions. The aim of this investigation was to evaluate the effects of EPs 7630 on chemokine production in nasal mucosa and clinical parameters of patients with acute postviral rhinosinusitis (APRS).

Methods

Twenty-six (n = 26) APRS patients and 25 (n = 25) control subjects were included in this prospective study. We measured the concentrations of thirteen chemokines in nasal secretions of APRS patients and controls by flow cytometry. The patients with APRS were treated by EPs 7630 20 mg oral tablets, three times daily for 10 days. We compared the chemokine levels in nasal secretions, nasal symptoms and endoscopic findings in patients, before and after therapy.

Results

We found higher Total Symptom Score (TSS) and higher concentrations of MCP-1, MIP-1α, MIP-1β, MIP-3α, ENA-78 and IL-8 in nasal secretions of APRS patients than in controls. After therapy by EPs 7630, we found significant improvement in all symptoms and endoscopic findings of APRS. The concentrations of MCP-1, IP-10 and MIP-1β were significantly increased and levels of MIP-1α, ENA-78, GROα and IL-8 significantly decreased in nasal fluid samples after therapy. No adverse effects were reported during the treatment.

Conclusion

Our results suggest the presence of modulatory effects of EPs 7630 on production of chemokines regulating the function of neutrophils and monocytes in the site of inflammation of the nasal mucosa in patients with APRS.

Herbal Drug EPs 7630 versus Amoxicillin in Patients with Uncomplicated Acute Bacterial Rhinosinusitis: A Randomized, Open-Label Study

OBJECTIVE

Previous investigations suggest the use of extract from the root of Pelargonium sidoides (EPs 7630) for the therapy of uncomplicated acute upper airway inflammations, due to its strong antimicrobial and immunomodulatory effect. We aimed to compare clinical efficacy, safety and bactericidal effect of EPs 7630 and amoxicillin monotherapy in treatment of patients with mild to moderate acute bacterial rhinosinusitis (ABRS).

METHODS

Fifty ABRS patients were divided into two groups by randomization. Group 1 (n = 25) received EPs 7630 tablets, 3 × 20 mg/day per os for 10 days. Group 2 (n = 25) received amoxicillin tablets 3 × 500 mg/day per os, for 10 days. We assessed total symptom score (TSS), individual symptom scores for each symptom (nasal obstruction, rhinorrhea, postnasal drip, facial pain/pressure, loss of the sense of smell), endoscopic findings, including total endoscopic score (TES) and individual endoscopic signs (mucosal edema, mucopurulent secretion), before and after treatment. Samples of discharge taken from the middle meatus of all patients were cultivated for bacteria before and after therapy.

RESULTS

Higher absolute improvement after treatment was found for TSS, nasal obstruction, facial pain/pressure, impaired sense of smell, TES, mucosal edema and mucopurulent secretion in EPs 7630 group compared to amoxicillin group (P < .001 for all parameters). However, there were no differences in absolute improvement of rhinorrhea score and postnasal drip score between groups (P = .248; P = .679, respectively). Fewer types of bacteria grew on culture from middle meatal samples in EPs 7630 group compared to amoxicillin group. There were no reported adverse events from patients from either group.

CONCLUSION

Our results demonstrated better clinical and antimicrobial efficacy of EPs 7630 than amoxicillin. EPs 7630 was shown as a potent agent and good alternative to antibiotic treatment of uncomplicated ABRS.

Efficacy of hypertonic (2.3%) sea water in patients with aspirin-induced chronic rhinosinusitis following endoscopic sinus surgery

BACKGROUND

Aspirin-induced chronic rhinosinusitis (CRS) is a severe progressive persistent disease, usually associated with nasal polyps (NPs).

AIM/OBJECTIVE

To compare effect of hypertonic (2.3% NaCl) sea water and isotonic 0.9% NaCl on symptoms and endoscopic findings in those patients in the period of 1 month after endoscopic sinus surgery (ESS).

MATERIAL AND METHODS

This prospective, randomized study included 30 patients with aspirin-induced CRS undergoing ESS. Patients were divided into two groups of 15 subjects and one of the two nasal irrigation solutions was administered in each group. Intensity of 5 symptoms (nasal obstruction, nasal discharge/postnasal drip, facial pain/pressure, headache and trouble sleeping) and endoscopic findings were assessed during the 1st, 7th, 14th, 21st and 28th days after the nasal packs removal.

RESULTS

We found significantly lower total symptom score (TSS) during the 7th (p = .009), 14th (p = .003), 21st (p < .001) and the 28th day (p = .001), lower total endoscopic score (TES) on the 21st (p = .002) and 28th day (p = .001), lower nasal obstruction, facial pain/pressure, headache and trouble sleeping, and lower nasal mucosal edema, nasal secretion and nasal crusting in patients treated by hypertonic sea water.

CONCLUSION AND SIGNIFICANCE

Hypertonic sea water should be recommended douching solution in the early postoperative care of patients with aspirin-induced CRS.
