Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial inflammatory disease, the treatment of which has undergone significant changes in recent years. In addition to surgical approaches, topical and systemic steroids, and adaptive acetylsalicylic acid (ASA) desensitization, three specific antibodies have complemented the therapeutic portfolio since 2019. METHODS A retrospective evaluation of all patients who presented as outpatients for the first time due to CRSwNP in 2007 and 2008 (collective A) and 2017 and 2018 (collective B) was performed, up to and including June 2023. RESULTS The clinical courses of 463 patients (mean age 49.1 years, range 5-82 years; 65.9% male) were included in the analysis. Conservative treatment with nasal corticosteroids started before initial presentation was more frequent in collective B (collective A 43.9% vs. collective B 72.2%). In 278 of the 463 patients (60%; A: 62%, B: 58%), at least one operation on the nasal sinuses had been performed after initial presentation; in 101 of these patients (36.3%) recurrent polyposis (within mean follow-up of 2.4 years) required further treatment. The indication for ASA provocation/desensitization was applied less frequently in collective B, also due to a high discontinuation rate (at least 38%) of the maintenance therapy. Of the total cohort, 16 patients (3.5%; A: n = 8, B: n = 8) were meanwhile switched to antibody therapy at recurrence. CONCLUSION A step-by-step guideline-orientated approach is recommended in the treatment of CRSwNP. Systemic antibodies as an add-on to nasal corticosteroids are a relatively new therapeutic option for treatment-refractory CRSwNP, which reduces the indication for ASA desensitization, which is associated with a relatively high incidence of side effects and poor compliance.

Abstract
PURPOSE An up-to-date overview of diagnosis, differential diagnosis, comorbidities, and current medical and surgical management of pediatric chronic rhinosinusitis (PCRS). METHODS Review of current evidence-based literature on PCRS. RESULTS Diagnosis of PCRS seems to be improving based on recent evidence using nasal endoscopy as well as computed tomography scanning. Recent literature supports the fact that chronic adenoiditis can be an independent etiology of symptoms of chronic sinusitis, that are very similar to chronic adenoiditis. Allergic rhinitis and immune deficiency play important roles in the management of PCRS. Surgery for PCRS has evolved significantly in the last 15-20 years to include adenoidectomy as well as endoscopic sinus surgery. CONCLUSIONS PCRS is very common in children causing poor QOL for these children. Medical management remains the main stay of treatment with attention to management of co-morbidities that may contribute to the disease severity. Making the correct diagnosis will help with the choice of surgical intervention if medical management fails.

Abstract
Objective: To evaluate the clinical efficacy of topical nasal Pomegranate Fruit Extract (PFE) for Chronic Rhinitis (CR), Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP), and Chronic Rhinosinusitis without Nasal Polyposis (CRSsNP). Methods: Prospective, double-blinded, randomized study including 111 consecutive patients, between April 2012 and January 2017, afflicted by CRSwNP, CRSsNP, and CR. Patients from each group were randomly assigned to either PFE treatment or placebo twice daily for 30 days. Therapeutic efficacy was assessed by Ear Nose and Throat, blood and tomographic examinations, and the SNOT-20 questionnaire. Results: CR patients treated with PFE suffered significantly less from thick nasal discharge, difficulty falling asleep, reduced productivity, reduced concentration, and sadness (P = .004, P = .02, P = .03, P = .007 and P = .02, respectively). Conclusions: Topical nasal PFE was found to have some benefits for CR patients, however, not for CRS with or without Nasal Polyposis.

J Inflamm Res 2024; 17:1295-1323. [PMID: 38434581 PMCID: PMC10906676 DOI: 10.2147/jir.s443420] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 01/23/2024] [Indexed: 03/05/2024] Open
Abstract
Rhinosinusitis (RS) is an acute (ARS) or chronic (CRS) inflammatory disease of the nasal and paranasal sinus mucosa. CRS is a heterogeneous condition characterized by distinct inflammatory patterns (endotypes) and phenotypes associated with the presence (CRSwNP) or absence (CRSsNP) of nasal polyps. Mucosal barrier and mucociliary clearance dysfunction, inflammatory cell infiltration, mucus hypersecretion, and tissue remodeling are the hallmarks of CRS. However, the underlying factors, their priority, and the mechanisms of inflammatory responses remain unclear. Several hypotheses have been proposed that link CRS etiology and pathogenesis with host (eg, "immune barrier") and exogenous factors (eg, bacterial/fungal pathogens, dysbiotic microbiota/biofilms, or staphylococcal superantigens). The abnormal interplay between these factors is likely central to the pathophysiology of CRS by triggering compensatory immune responses. Here, we discuss the role of the sinonasal microbiota in CRS and its biofilms in the context of mucosal zinc (Zn) deficiency, serving as a possible unifying link between five host and "bacterial" hypotheses of CRS that lead to sinus mucosa remodeling. To date, no clear correlation between sinonasal microbiota and CRS has been established. However, the predominance of Corynebacteria and Staphylococci and their interspecies relationships likely play a vital role in the formation of the CRS-associated microbiota. Zn-mediated "nutritional immunity", exerted via calprotectin, alongside the dysregulation of Zn-dependent cellular processes, could be a crucial microbiota-shaping factor in CRS. Similar to cystic fibrosis (CF), the role of SPLUNC1-mediated regulation of mucus volume and pH in CRS has been considered. We complement the biofilms' "mechanistic" and "mucin" hypotheses behind CRS pathogenesis with the "structural" one - associated with bacterial "corncob" structures. Finally, microbiota restoration approaches for CRS prevention and treatment are reviewed, including pre- and probiotics, as well as Nasal Microbiota Transplantation (NMT).

Infect Drug Resist 2023; 16:7029-7040. [PMID: 37954509 PMCID: PMC10638656 DOI: 10.2147/idr.s433439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/09/2023] [Indexed: 11/14/2023] Open
Abstract
Objective To investigate the antibacterial impact of daptomycin and azithromycin in vitro on methicillin-resistant Staphylococcus aureus (MRSA) biofilm. Methods (1) Measure the strain growth curve and the biofilm formation curve. (2) Determine the minimum inhibitory concentrations (MICs) of daptomycin and azithromycin. (3) Investigate the antibacterial impact of the combination of daptomycin and azithromycin. (4) Perform the evaluation of the intervention impact of antimicrobial agents on MRSA biofilm. (5) Observe the biofilm after intervention with the antibacterial agent. Results (1) MRSA exhibited three phases: lag phase (0-4 h), logarithmic growth (4-8 h) and stationary phase after 18 h; its biofilm began to form at 6 h, semi-matured at 24 h, and reached maturity after 48 h. (2) The MICs of daptomycin and azithromycin were 8 μg/mL and greater than 256 μg/mL, respectively. (3) The combination of daptomycin and azithromycin has an additive effect on MRSA (Fractional Inhibitory Concentration Index [FICI] 0.625) (FICI = MIC of drug A in combination/MIC of drug A alone + MIC of drug B in combination/MIC of drug B alone). Evaluation criteria: Synergistic effect is considered when FICI ≤ 0.5; additive effect is considered when 0.5 < FICI ≤ 1; irrelevant effect is considered when 1 < FICI ≤ 2; antagonistic effect is considered when FICI > 2). (4) Daptomycin or azithromycin at MICs inhibited not only the growth of planktonic bacteria but also the formation of biofilm. (5) The combination of both, in which group the ratio of live/dead bacteria is low and the biofilm morphology was incomplete, was more productive than monotherapy in against biofilm. Conclusion Both daptomycin and azithromycin have anti-MRSA biofilm activity, and daptomycin is dominant. The fact that the combination of both can significantly inhibit the further maturation of MRSA biofilm and destroy already formed biofilm demonstrates the superiority of the combination over the monotherapy.

Abstract
Chronic rhinosinusitis (CRS) is a common chronic sinonasal mucosal inflammation associated with Staphylococcus aureus biofilm and relapsing infections. This study aimed to determine rates of S. aureus persistence and pathoadaptation in CRS patients by investigating the genomic relatedness and antibiotic resistance/tolerance in longitudinally collected S. aureus clinical isolates. A total of 68 S. aureus paired isolates (34 pairs) were sourced from 34 CRS patients at least 6 months apart. Isolates were grown into 48 h biofilms and tested for tolerance to antibiotics. A hybrid sequencing strategy was used to obtain high-quality reference-grade assemblies of all isolates. Single nucleotide variants (SNV) divergence in the core genome and sequence type clustering were used to analyse the relatedness of the isolate pairs. Single nucleotide and structural genome variations, plasmid similarity, and plasmid copy numbers between pairs were examined. Our analysis revealed that 41 % (14/34 pairs) of S. aureus isolates were persistent, while 59 % (20/34 pairs) were non-persistent. Persistent isolates showed episode-specific mutational changes over time with a bias towards events in genes involved in adhesion to the host and mobile genetic elements such as plasmids, prophages, and insertion sequences. Furthermore, a significant increase in the copy number of conserved plasmids of persistent strains was observed. This was accompanied by a significant increase in biofilm tolerance against all tested antibiotics, which was linked to a significant increase in biofilm biomass over time, indicating a potential biofilm pathoadaptive process in persistent isolates. In conclusion, our study provides important insights into the mutational changes during S. aureus persistence in CRS patients highlighting potential pathoadaptive mechanisms in S. aureus persistent isolates culminating in increased biofilm biomass.

Abstract
Chronic rhinosinusitis is a condition characterized by inflammation of the paranasal sinuses causing several symptoms, including facial pain, anosmia, nasal drainage, and obstruction for a minimal duration of three months. It is a commonly occurring disease and is diagnosed through direct visualization or the detection of inflammation on a CT scan. A mucosal tissue biopsy typically reveals stromal fibrosis and an increase in submucosal glands, and infiltration of mixed mononuclear cells, neutrophils, and eosinophils may also be present but typically makes up less than 10% of the total cells. T helper type 2 releasing cytokines, interleukins (IL-5 and IL-13), as well as histamine, are frequently found in high concentrations in polyp tissue. We report a case of rare chronic rhinosinusitis. The patient's specimen shows a very high number of immunoglobulin G4 (IgG4)-positive plasma cells.

Abstract
Background: Thrombophilia due to Protein C deficiency is a rare condition, present in 0.2% of general population. Cerebral venous thrombosis has an incidence of 3-4 cases per million in adults. A combination of both is very uncommon. Patients with these conditions are prone to life-threatening superinfections.
Case: A 51-year-old woman presented with pressing frontal headache accompanied with left periorbital edema, fever, diplopia, and disorientation. Laboratory findings showed low protein C levels. Computed tomography demonstrated sphenoidal rhinosinusitis. Magnetic resonance venography revealed cavernous sinus thrombosis. The patient was started on empiric antibiotic treatment (vancomycin, ceftriaxone, and metronidazole) and anticoagulants.
Conclusion: This case report emphasizes the importance of early diagnosis and appropriate management of patients with protein C deficiency complicated by septic cavernous sinus thrombosis.

Abstract
PURPOSE OF REVIEW Control is a global disease metric defined as the extent to which manifestations of a disease are within acceptable limits. Control serves as the goal of treatment for chronic diseases, such as chronic rhinosinusitis (CRS), that cannot be cured. The objective of this review is to summarize recommendations for assessment of CRS control with a specific focus on how these recommendations align with patients' and healthcare providers' perspectives of CRS control. RECENT FINDINGS Several staging systems for CRS control have been developed with the first and most widely recognized by the 2012 European Position Paper on Rhinosinusitis and Nasal Polyps, which was developed through expert opinion. Patients' and providers'/guideline-based assessments of CRS control frequently do not align. Patients understand the concept of CRS control and their assessment is dominated by the perceived severity of nasal symptoms. In comparison, providers' and guideline-based assessments of control are more global, incorporating nasal and extra-nasal symptoms, need for systemic antibiotics and corticosteroids, and nasal endoscopy. SUMMARY Although more research is needed, future development of CRS control criteria through consensus around explicitly determined perspectives of healthcare providers and patients may one day serve as the foundation for a standardized approach to treatment of CRS.

Abstract
BACKGROUND Macrolides have shown beneficial effects in the treatment of chronic rhinosinusitis (CRS). This study aimed to compare the effect of azithromycin and clarithromycin in combination with conventional therapies for the treatment of CRS. METHODS This single-blind randomized controlled trial was conducted during 2018-2019 at the Otorhinolaryngology Clinic of Shahid Mohammadi Hospital, Bandar Abbas, Iran. Out of 102 selected patients, 90 were included in the analysis. Patients were selected through convenience sampling and randomly assigned to two equal groups. In addition to conventional therapies (nasal irrigation, betamethasone injection, oxymetazoline and fluticasone spray, guaifenesin syrup, and steam inhalation), the patients in the clarithromycin group received clarithromycin 500 mg tablets twice daily for four weeks. The other group received azithromycin 500 mg tablets daily for four weeks. Patients' symptoms were evaluated pre- and post-intervention, and the Lund-Mackay (LM) scoring system was used for the staging of CRS based on computed tomography scan findings. Data were analyzed using SPSS software, and P<0.05 was considered statistically significant. RESULTS Patients in both groups were comparable in terms of age and sex. Complete resolution of symptoms was significantly higher in the azithromycin group than the clarithromycin group (71.1% vs. 24.4%, P<0.001). Baseline LM scores did not differ significantly between the groups (P=0.120). However, post-intervention, LM scores reduced considerably in both groups, but the change was significantly higher in the azithromycin group (P<0.001). CONCLUSION In combination with conventional therapies for CRS in adults, a four-week course of treatment with azithromycin is more effective than clarithromycin.Trial Registration Number: IRCT20201209049661N1.

Abstract
OBJECTIVE The objective of this systematic review and meta-analysis was to evaluate the role of doxycycline in the management of chronic rhinosinusitis. METHOD This was a systematic review using Ovid Medline, Cinahl, Scopus and Cochrane and was limited to meta-analyses, systematic reviews and randomised, clinical trials. A combination of the following search terms was used: 'sinusitis', 'nasal polyps', 'doxycycline' and 'tetracycline'. Raw means and standard deviations were extracted from the included studies. The meta-analysis was performed using mean differences of pre- versus post-doxycycline treatment. RESULTS A total of 279 studies were screened, of which 5 studies met the criteria (all randomised, controlled trials published between 2010 and 2021). The interventions, endpoints and measured outcomes varied across all studies. Meta-analysis performed on pre- versus post-doxycycline treatment for Sino-Nasal Outcome Test-22, nasal polyp scores and symptom scores did not yield statistically significant results. CONCLUSION This review identified a small number of high-quality studies on the use of doxycycline in chronic rhinosinusitis. There does not seem to be convincing evidence for the routine use of doxycycline in patients with chronic rhinosinusitis. Further research may try to identify certain phenotypes of chronic rhinosinusitis that may better respond to doxycycline.

Abstract
An important role has been recently reported for bacterial biofilm in the pathophysiology of chronic diseases, such as chronic rhinosinusitis (CRS). CRS, affecting sinonasal mucosa, is a persistent inflammatory condition with a high prevalence around the world. Although the exact pathological mechanism of this disease has not been elicited yet, biofilm formation is known to lead to a more significant symptom burden and major objective clinical indicators. The high prevalence of multidrug-resistant bacteria has severely restricted the application of antibiotics in recent years. Furthermore, systemic antibiotic therapy, on top of its insufficient concentration to eradicate bacteria in the sinonasal biofilm, often causes toxicity, antibiotic resistance, and an effect on the natural microbiota, in patients. Thus, coming up with alternative therapeutic options instead of systemic antibiotic therapy is emphasized in the treatment of bacterial biofilm in CRS patients. The use of topical antibiotic therapy and antibiotic eluting sinus stents that induce higher antibiotic concentration, and decrease side effects could be helpful. Besides, recent research recognized that various natural products, nitric oxide, and bacteriophage therapy, in addition to the hindered biofilm formation, could degrade the established bacterial biofilm. However, despite these improvements, new antibacterial agents and CRS biofilm interactions are complicated and need extensive research. Finally, most studies were performed in vitro, and more preclinical animal models and human studies are required to confirm the collected data. The present review is specifically discussing potential therapeutic strategies for the treatment of bacterial biofilm in CRS patients.

Chronic Rhinosinusitis and Alzheimer's Disease-A Possible Role for the Nasal Microbiome in Causing Neurodegeneration in the Elderly. Int J Mol Sci 2021; 22:ijms222011207. [PMID: 34681867 PMCID: PMC8541405 DOI: 10.3390/ijms222011207] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 10/08/2021] [Accepted: 10/14/2021] [Indexed: 12/25/2022] Open
Abstract
Among millions of sufferers of chronic rhinosinusitis (CRS), the challenge is not only constantly coping with CRS-related symptoms, such as congested nose, sinus pain, and headaches, but also various complications, such as attention difficulties and possible depression. These complications suggest that neural activity in the central nervous system may be altered in those patients, leading to unexpected conditions, such as neurodegeneration in elderly patients. Recently, some studies linked the presence of CRS and cognitive impairments that could further develop into Alzheimer’s disease (AD). AD is the leading cause of dementia in the elderly and is characterised by progressive memory loss, cognitive behavioural deficits, and significant personality changes. The microbiome, especially those in the gut, has been recognised as a human organ and plays an important role in the development of various conditions, including AD. However, less attention has been paid to the microbiome in the nasal cavity. Increased nasal inflammatory responses due to CRS may be an initial event that changes local microbiome homeostasis, which may further affect neuronal integrity in the central nervous system resulting in AD. Evidence suggests a potential of β-amyloid deposition starting in olfactory neurons, which is then expanded from the nasal cavity to the central nervous system. In this paper, we reviewed currently available evidence that suggests this potential mechanism to advise the need to investigate the link between these two conditions.

Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) affects approximately 12% of the population and leads to increased health care utilization and indirect costs exceeding $20 billion annually in the United States. The Lund-Mackay score (LMS) measures radiographic disease severity for CRS but poorly correlates with symptom scores. The association between LMS and health care utilization in CRS patients has not yet been investigated. The study aimed to assess the association between health care utilization and CRS radiographic severity using LMS. METHODS CRS patients enrolled in a clinical registry were evaluated. Nasal endoscopy findings and LMS were recorded for patients with sinus CT imaging. Patient symptom scores, demographic characteristics, and health care utilization measures were collected. The relationship between these factors and LMS was examined. RESULTS A total of 556 patients met inclusion criteria. Mean age was 45.3 years, 53.4% were male, and 41.7% had nasal polyps. There was no difference in sex, smoking history, 22-item Sino-nasal Outcome Test scores, or past medical history factors between patients with high (≥8, n = 410) and low (<8, n = 146) LMS. Among high LMS patients, 73.7% underwent endoscopic sinus surgery (ESS) compared to 55.5% with low LMS (P < .01), and a greater percentage of patients had nasal polyps (49.3% vs 20.5%, P < .01). On multivariable logistic regression, high LMS patients used fewer antibiotic courses (OR: 0.68 [0.51-0.91]), but were more likely to be managed with ESS (OR: 2.28 [1.41-3.73]), and have nasal polyps (OR: 2.11 [1.16-3.93]) compared to low LMS patients. There was no significant difference in the number of steroid courses, over the counter pill use, provider visits, work/school days missed, or symptom duration between the two LMS groups. CONCLUSION CRS patients with severe radiographic disease are more likely to have nasal polyps, undergo ESS, and take fewer antibiotic courses. However, there is no association between radiographic disease severity and other measures of health care utilization. LEVEL OF EVIDENCE 2b, individual retrospective cohort study.

Abstract
PURPOSE Chronic rhinosinusitis (CRS) is a heterogeneous chronic inflammatory condition of the paranasal sinuses and nasal passages. Although antibiotics are used to reduce inflammation or to treat an episode of acute rhinosinusitis, their effects on the nasal environment and host response in CRS is unclear. METHODS We analyzed the effects of antibiotics on the nasal microbiome and secreted proteome in CRS using multi-omic analysis. Nasal secretions were collected from 29 controls, 30 CRS patients without nasal polyps (NP), and 40 CRS patients with NP. A total of 99 subjects were divided into 2 groups that included subjects who had taken antibiotics 3 months prior to sampling and those who had not. We performed 16S ribosomal DNA sequence analyses and Orbitrap mass spectrometry-based proteomic analyses. Spearman correlation was used to assess the correlations between the nasal microbiome and secreted proteome. RESULTS The associations between the nasal microbiome and secreted proteome were noted in subjects who had used antibiotics. Antibiotics could have stronger effects on their associations in patients with CRS with NP than in those without. It remains unknown whether these holistic changes caused by antibiotics are beneficial or harmful to CRS, however, the associations could be differentially affected by disease severity. CONCLUSION These findings provide new insight into the nasal environment and the host response in CRS.

Abstract
Background Chronic rhinosinusitis (CRS) is a common and debilitating inflammatory condition of the sinuses, afflicting 5% of the general population. Although antibiotics are frequently prescribed for the medical management of CRS, there is surprisingly little evidence to support their efficacy. In this study, we aimed to establish associations between medication usage, the sinus microbiota and patients’ clinical outcomes. Methods Antibiotic prescription patterns for the year before sample collection of 156 CRS patients, 45 disease control patients (mostly requiring septoplasty and inferior turbinate reduction) and 35 healthy control subjects were examined and analyzed together with previously published bacterial 16S rRNA gene amplicon data from our group. Results The highest antibiotic usage was observed among the two CRS patient categories. Despite heavy antibiotic usage, CRS patients’ clinical outcomes as indicated by patient questionnaires and radiologic scores were similar to those patients that did not receive any antibiotics. The sinus microbiota was dominated by members of the bacterial genera Corynebacterium and Staphylococcus in all three cohorts. Bacterial community dispersion as measured by principal coordinate analysis was significantly higher in CRS patients compared to healthy control subjects, but not disease control patients. Pairwise comparisons within cohorts revealed differences in the relative 16S rRNA gene sequence abundances of the genera Staphylococcus and Lawsonella between antibiotic users and non-users. However, overall antibiotic effects were minimal and unpredictable. Conclusion The unpredictable effects of antibiotic treatment on the sinus microbiota found in this study, together with the lack of differences in patients’ symptom scores between cohorts, do not support preoperative antibiotic treatment for CRS patients.

Abstract
Chronic rhinosinusitis (CRS) is a chronic disease that involves long-term inflammation of the nasal cavity and paranasal sinuses. Bacterial biofilms present on the sinus mucosa of certain patients reportedly exhibit resistance against traditional antibiotics, as evidenced by relapse, resulting in severe disease. The aim of this study was to determine the killing activity of human cathelicidin antimicrobial peptides (LL-37, LL-31) and their D-enantiomers (D-LL-37, D-LL-31), alone and in combination with conventional antibiotics (amoxicillin; AMX and tobramycin; TOB), against bacteria grown as biofilm, and to investigate the biological activities of the peptides on human lung epithelial cells. D-LL-31 was the most effective peptide against bacteria under biofilm-stimulating conditions based on IC50 values. The synergistic effect of D-LL-31 with AMX and TOB decreased the IC50 values of antibiotics by 16-fold and could eliminate the biofilm matrix in all tested bacterial strains. D-LL-31 did not cause cytotoxic effects in A549 cells at 25 μM after 24 h of incubation. Moreover, a cytokine array indicated that there was no significant induction of the cytokines involving in immunopathogenesis of CRS in the presence of D-LL-31. However, a tissue-remodeling-associated protein was observed that may prevent the progression of nasal polyposis in CRS patients. Therefore, a combination of D-LL-31 with AMX or TOB may improve the efficacy of currently used antibiotics to kill biofilm-embedded bacteria and eliminate the biofilm matrix. This combination might be clinically applicable for treatment of patients with biofilm-associated CRS.

Abstract
Bacterial biofilm formation and antibiotic resistance are the main factors of surgical wound complications. Traditional treatments in some cases cannot provide complete bacterial eradication and new therapeutic approaches should be developed to overcome antibiotic resistance. Silver nanoparticles (AgNPs) can be the first choice for bacteria treatment but their clinical application is limited due to toxic effects. Combination of AgNPs with the low-frequency ultrasound (US) treatment expected to decrease toxicity and leads to the facilitation of wound healing. In current research we investigated the antibacterial activity of AgNPs per se and in combination with low-frequency US, assessed the cytotoxicity of AgNPs on human dermal fibroblasts and finally, wound healing was evaluated in purulent wound model (96 white laboratory rats) applying AgNPs and US as a treatment strategy. Our results demonstrate no toxic effect of AgNPs in minimum inhibitory concentrations and show increasing their antibacterial effectiveness after US application. The combination of low-frequency US and AgNPs provides reduction of the inflammatory reaction, microorganism elimination and leads to facilitation of new tissue formation with complete epithelization. All effects were significant over the Chlorhexidine treatment, monotherapy with AgNPs or US. Advanced effectiveness of complex therapy opens new perspectives for clinical application of AgNPs solution accompanied by US.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) is associated with a significant decrease in general health-related quality of life (QOL). The EuroQol 5-dimensional questionnaire measures general health-related quality of life through a health utility value (EQ-5D HUV)-based on five domains reflecting mobility, self-care, activities of daily life, pain/discomfort, and anxiety/depression-and an unbiased visual analog scale (EQ-5D VAS). We sought to identify characteristics of CRS patients with a high EQ-5D HUV but low EQ-5D VAS score. MATERIALS AND METHODS Retrospective cross-sectional study of 300 CRS patients with EQ-5D HUV equal to 1.0 (reflecting perfect health). All patients completed a 22-item Sinonasal Outcome Test (SNOT-22)-from which nasal, sleep, ear/facial discomfort, and emotional subdomain scores were calculated, as well as the EQ-5D. Low EQ-5D VAS was defined as a score less than 80. RESULTS On multivariate analysis, low EQ-5D VAS was associated with only the SNOT-22 sleep subdomain score (odds ratio [OR] = 1.07, 95%CI: 1.02-1.12, P = .003). Comorbid asthma was also associated with lower EQ-5D VAS (OR = 2.16, 95%CI: 1.02-4.59, P = .045). In contrast, polyps were negatively associated with having a lower EQ-5D VAS (OR = 0.34, 95%CI: 0.17-0.69, P = .003). CONCLUSION There are patients with perfect general health-related QOL according to a health utility value-based methodology (like the EQ-5D HUV) who report low general health-related QOL on an unbiased measure like the EQ-5D VAS. In CRS patients with perfect EQ-5D HUV, poor sleep and asthma were associated with low QOL on the EQ-5D VAS, while polyps were negatively associated with low QOL.

Azithromycin and ciprofloxacin inhibit interleukin-8 secretion without disrupting human sinonasal epithelial integrity in vitro. Int Forum Allergy Rhinol 2020; 11:136-143. [PMID: 32725797 DOI: 10.1002/alr.22656] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/16/2020] [Accepted: 06/26/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND We recently developed a ciprofloxacin and azithromycin sinus stent (CASS) to target recalcitrant infections in chronic rhinosinusitis (CRS). The objective of this study was to evaluate the anti-inflammatory activity of azithromycin released from the CASS and assess the impact on the integrity and function of primary human sinonasal epithelial cells (HSNECs). METHODS Pseudomonas aeruginosa lipopolysaccharide (LPS)-stimulated HSNECs were treated with azithromycin and/or ciprofloxacin at concentrations attainable from CASS release. Interleukin-8 (IL-8) secretion was quantified by enzyme-linked immunosorbent assay (ELISA). Epithelial integrity (transepithelial resistance [TEER], paracellular permeability [fluorescein isothiocyanate-labeled dextran], lactate dehydrogenase [LDH] assays) and function (ciliary beat frequency [CBF]) were also evaluated. RESULTS Azithromycin significantly reduced secreted IL-8 from P. aeruginosa LPS-stimulated HSNECs at all concentrations tested (mean ± standard deviation; control = 5.77 ± 0.39 ng/mL, azithromycin [6 μg/mL] = 4.58 ± 0.40 ng/mL, azithromycin [60 µg/mL] = 4.31 ± 0.06, azithromycin [180 µg/mL] = 4.27 ± 0.26 ng/mL, p < 0.05). Co-incubation with azithromycin (6 µg/mL) and ciprofloxacin (2.4 µg/mL) in LPS-stimulated HSNECs also displayed a significant reduction in secreted IL-8 when compared to P. aeruginosa LPS alone (co-treatment = 4.61 ± 0.29 ng/mL, P. aeruginosa LPS = 7.35 ± 0.89 ng/mL, p < 0.01). The drugs did not negatively impact TEER, paracellular permeability, LDH release, or CBF, indicating retention of cell integrity and function. CONCLUSION Azithromycin decreased P. aeruginosa LPS IL-8 production in HSNECs at drug concentrations attainable with sustained release of azithromycin from the CASS. In addition to antibacterial activity, anti-inflammatory properties of the CASS should provide further benefit for patients with recalcitrant CRS.

Laryngoscope 2020; 131:707-712. [PMID: 32628769 DOI: 10.1002/lary.28879] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 03/16/2020] [Accepted: 05/29/2020] [Indexed: 12/23/2022]
Abstract
OBJECTIVES Chronic rhinosinusitis (CRS), like other sinonasal diseases, may be associated with avoidance of daily activities. Our goal was to identify characteristics associated with avoidance of activities due to CRS. MATERIALS AND METHODS A total of 194 CRS patients were recruited. CRS symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). SNOT-22 nasal, sleep, ear/facial discomfort and emotional/psychological subdomain scores were calculated. Depressed mood was assessed using the two-item Patient Health Questionnaire (PHQ-2). Personality traits including conscientiousness, neuroticism, agreeableness, openness, and extraversion were assessed using the Big Five Inventory-10 (BFI-10) questionnaire. As the primary outcome, participants rated how often in the prior week that they had avoided any activities in day-to-day life due to their nasal or sinus symptoms on a scale of "never," "rarely," "sometimes," "often," or "extremely often." Ordinal regression models, with bootstrap validation, were used to identify associations between activity avoidance and participants' characteristics. RESULTS On multivariable analysis, SNOT-22 score (odds ratio [OR] = 1.03, 95% CI, 1.01-1.04, P = .026), and conscientiousness personality trait (OR = 1.38, 95% CI, 1.05-1.81, P = .019) were positively associated with activity avoidance while age (OR = 0.98, 95% CI, 0.96-0.99, P = .049) was negatively associated with activity avoidance. Of CRS symptom burden/SNOT-22 subdomains, only the emotional/psychological subdomain score (OR = 1.28, 95% CI, 1.12-1.46, P < .001) was associated with activity avoidance. CONCLUSION Younger age and the conscientiousness personality trait were associated with activity avoidance in CRS patients. Of CRS-associated symptomatology, sadness and embarrassment were associated with activity avoidance. Emotional traits and personality most strongly predict avoidance of activities in CRS patients.

Escherichia coli Strains with Virulent Factors Typical for Uropathogens were Isolated from Sinuses from Patients with Chronic Rhinosinusitis-Case Report. Pathogens 2020; 9:pathogens9050318.

Abstract
Escherichia coli were isolated from three patients with chronic rhinosinusitis (CRS) by intraoperative sinus tissue biopsy. Taking into account the unusual replicative niche and previous treatment failures, it was decided to focus on the virulence and drug resistance of these bacteria. The strains turned out to be multi-sensitive, but the rich virulence factors profile of bacteria typical for phylogenetic group B2 deserved attention. Tests were carried out for the presence of 32 genes using the PCR method. Particularly noteworthy are the toxins Cnf-1, HlyA, Usp-an extensive iron uptake system (enterobactin, salmochelin, yersiniabactin and outer membrane hemin receptor ChuA)-SPATE autotransporters such as vat and pic, Ag43 autoaggregative protein-important for biofilm formation-and TosA/B which enhance the fitness of E.coli. All these virulence factors are identified predominantly in UPEC strains and provide a fitness advantage during colonization of the sinuses. Patients with CRS should be asked for past or present UTI. The specific virulence factors of E. coli that facilitate the colonization of the GI tract and urinary tract may also favor the colonization of a new ecological niche (sinuses) as a result of microbial imbalance or dysbiosis.

Abstract
OBJECTIVE To review the diagnosis of chronic wound biofilms and discuss current treatment approaches. DATA SOURCES Articles included in this review were obtained from the following databases: Wanfang, China National Knowledge Infrastructure, PubMed, and the Web of Science. We focused on research published before August 2019 with keywords including chronic wound, biofilm, bacterial biofilms, and chronic wound infection. STUDY SELECTION Relevant articles were selected by carefully reading the titles and abstracts. Further, different diagnosis and clinical treatment methods for chronic wound biofilm were compared and summarized from the selected published articles. RESULTS Recent guidelines on medical biofilms stated that approaches such as the use of scanning electron microscopy and confocal laser scanning microscopy are the most reliable types of diagnostic techniques. Further, therapeutic strategies include debridement, negative pressure wound therapy, ultrasound, antibiotic, silver-containing dressing, hyperbaric oxygen therapy, and others. CONCLUSION This review provides the identification and management of biofilms, and it can be used as a tool by clinicians for a better understanding of biofilms and translating research to develop best clinical practices.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a chronic inflammatory disease characterized by persistent inflammation and bacterial infection. Ciprofloxacin and azithromycin are commonly prescribed antibiotics for CRS, but the ability to provide targeted release in the sinuses could mitigate side effects and improve drug concentrations at the infected site. This study was aimed to evaluate the efficacy of the novel ciprofloxacin-azithromycin sinus stent (CASS) in vitro. METHODS The CASS was created by coating ciprofloxacin (hydrophilic, inner layer) and azithromycin (hydrophobic, outer layer) onto a biodegradable poly-l-lactic acid (PLLA) stent. In-vitro evaluation included: (1) assessment of drug-coating stability within the stent using scanning electron microscopy (SEM); (2) determination of ciprofloxacin and azithromycin release kinetics; and (3) assessment of anti-biofilm activities against Pseudomonas aeruginosa. RESULTS The ciprofloxacin nanoparticle suspension in the inner layer was confirmed by zeta potential. Both ciprofloxacin (60 µg) and azithromycin (3 mg) were uniformly coated on the surface of the PLLA stents. The CASS showed ciprofloxacin/azithromycin sustained release patterns, with 80.55 ± 11.61% of ciprofloxacin and 93.85 ± 6.9% of azithromycin released by 28 days. The CASS also significantly reduced P aeruginosa biofilm mass compared with bare stents and controls (relative optical density units at 590-nm optical density: CASS, 0.037 ± 0.006; bare stent, 0.911 ± 0.015; control, 1.000 ± 0.000; p < 0.001; n = 3). CONCLUSION The CASS maintains a uniform coating and sustained delivery of ciprofloxacin and azithromycin, providing anti-biofilm activities against P aeruginosa. Further studies evaluating the efficacy of CASS in a preclinical model are planned.

Abstract
The chronically inflamed mucosa in patients with chronic rhinosinusitis (CRS) can additionally be infected by bacteria, which results in an acute exacerbation of the disease (AECRS). Currently, AECRS is universally treated with antibiotics following the guidelines for acute bacterial rhinosinusitis (ABRS), as our understanding of its microbiology is insufficient to establish specific treatment recommendations. Unfortunately, antibiotics frequently fail to control the symptoms of AECRS due to biofilm formation, disruption of the natural microbiota, and arising antibiotic resistance. These issues can potentially be addressed by phage therapy. In this study, the endoscopically-guided cultures were postoperatively obtained from 50 patients in order to explore the microbiology of AECRS, evaluate options for antibiotic treatment, and, most importantly, assess a possibility of efficient phage therapy. Staphylococcus aureus and coagulase-negative staphylococci were the most frequently isolated bacteria, followed by Haemophilus influenzae, Pseudomonas aeruginosa, and Enterobacteriaceae. Alarmingly, mechanisms of antibiotic resistance were detected in the isolates from 46% of the patients. Bacteria not sensitive to amoxicillin were carried by 28% of the patients. The lowest rates of resistance were noted for fluoroquinolones and aminoglycosides. Fortunately, 60% of the patients carried bacterial strains that were sensitive to bacteriophages from the Biophage Pharma collection and 81% of the antibiotic-resistant strains turned out to be sensitive to bacteriophages. The results showed that microbiology of AECRS is distinct from ABRS and amoxicillin should not be the antibiotic of first choice. Currently available bacteriophages could be used instead of antibiotics or as an adjunct to antibiotics in the majority of patients with AECRS.

Abstract
PURPOSE The effects of nasal obstruction in patients with chronic rhinosinusitis (CRS) are associated with depressed mood. We sought to validate this finding by determining whether improvement in nasal obstruction would translate to improvement in depressed mood. METHODS This was a prospective observational study of 150 patients undergoing medical management for CRS. Data were collected at two timepoints: enrollment and a subsequent follow-up visit 3-12 months later. Impact of nasal obstruction was measured using the Nasal Obstruction Symptom Evaluation (NOSE) instrument and depressed mood was measured using the 2-item Patient Health Questionnaire (PHQ-2). Sinonasal symptoms associated with CRS were also measured using the 22-item Sinonasal Outcome Test (SNOT-22). Clinical and demographic characteristics were collected. The relationship between changes in PHQ-2 and NOSE scores was determined with correlation and linear regression. RESULTS Change in PHQ-2 score was significantly correlated with change in NOSE score (ρ = 0.30, p < 0.001). After controlling for covariates, change in PHQ-2 score was associated with change in NOSE score (adjusted linear regression coefficient [β] = 0.014, 95% CI 0.006-0.022, p = 0.001). We confirmed these relationships, finding that change in PHQ-2 was associated (adjusted β = 0.037, 95% CI 0.013-0.061, p = 0.003) with change in the nasal subdomain score of the SNOT-22. Improvement in NOSE score by greater than 22 points was predictive of improvement in PHQ-2 score with sensitivity 54.5% and 83.8% specificity (p < 0.001). CONCLUSION These results provide evidence that improvements in nasal manifestations/symptoms of CRS translate to significant improvements in mood.

Abstract
PURPOSE Microbial biofilms have been implicated in the pathogenesis of chronic rhinosinusitis with nasal polyposis (CRSwNP). The aim of our study was to evaluate in vitro effects of amoxicillin-clavulanic acid and levofloxacin on biofilm formation by bacterial species isolated from sinus tissue in patients with CRSwNP. METHODS The sinus mucosal specimens were harvested from the upper parts and roof of ethmoid cavity of 48 patients with CRSwNP. Each sample was washed thoroughly in three separate beakers of sterile saline to remove any planktonic bacteria and further subjected to microbiology analysis. The biofilm-forming capacity of isolated strains was detected by microtiter-plate method and the effects of subinhibitory (1/2× to 1/16× MIC) and suprainhibitory concentrations (4, 8, 16, 32, and 64 µg/ml) of amoxicillin-clavulanic acid and levofloxacin on biofilm production were investigated. RESULTS Bacterial strains were isolated in 42 (87.5%) patients: one microorganism in 80.9% and two microorganisms in 19.1% of patients. The most prevalent bacteria in CRSwNP biofilms were Staphylococcus epidermidis (34%) and S. aureus (28%) followed by S. haemolyticus (12%), Pseudomonas aeruginosa (8%), Moraxella catarrhalis (6%), Streptococcus pneumoniae (6%), and other staphylococci (6%). Subinhibitory concentrations of amoxicillin-clavulanic acid and levofloxacin significantly reduced biofilm formation (p < 0.01 and p < 0.05, respectively), with better efficacy of amoxicillin-clavulanic acid (1/2-1/8× MIC) on staphylococci and levofloxacin (1/2- 1/4× MIC) on M. catarrhalis and P. aeruginosa biofilm formation. Suprainhibitory concentrations of both tested antibiotics (4-64 µg/ml) significantly eradicated mature biofilms of staphylococci (p < 0.01). The effect of levofloxacin on eradication of staphylococcal biofilms was more noticeable, compared to the effect of amoxicillin-clavulanic acid (p < 0.01). Suprainhibitory concentrations of both tested antibiotics had no effect on eradication of previously formed M. catarrhalis and P. aeruginosa biofilms (p > 0.05). CONCLUSIONS The amoxicillin-clavulanic acid and levofloxacin are shown to be potent antibiofilm agents in patients with CRSwNP. The effects of tested compounds depend on bacterial species and the volume of formed biofilm.

Abstract
BACKGROUND Antibiotics and corticosteroids are prescribed to patients with chronic rhinosinusitis (CRS) to reduce bacterial burden and mucosal inflammation. Unfortunately, clinical improvement is often short-lived and symptoms frequently recur following cessation of treatment. The impact of these systemic therapies on bacterial communities is not well understood. Improved knowledge of how medical therapies influence the intranasal ecosystem may allow for more effective prescribing and the development of more targeted treatments. METHODS Twenty patients with CRS were randomized to receive either doxycycline 100 mg twice daily or prednisone 30 mg once daily for 7 days. A further 6 patients with CRS were recruited as untreated controls. Swabs were taken immediately before and after the study period. Symptom scores (22-item Sino-Nasal Outcome Test [SNOT-22]) were recorded. Bacterial communities were characterized using 16S ribosomal RNA (rRNA) gene-targeted amplicon sequencing. Bacterial abundance was estimated using quantitative polymerase chain reaction (PCR) of 16S rRNA gene copies. RESULTS Bacterial profiles were dominated by members of the genera Corynebacterium and Staphylococcus. Patients treated with either doxycycline or prednisone had variable and unpredictable changes in communities. The average relative abundance of Propionibacterium increased after treatment in the doxycycline treatment group, and Corynebacterium reduced in the prednisone group. Significant differences in clinical scores, bacterial community richness, diversity, and bacterial abundance were not seen after treatment. CONCLUSION The short-term response of bacterial communities to antibiotic or corticosteroid therapy is unpredictable. This study suggests that the use of systemic therapy in patients with stable CRS should be rationalized to minimize antibiotic-associated morbidity and bacterial dysbiosis.
