Abstract
This review examines the complex connection between commensal microbiota and the development of opportunistic infections. Several underlying conditions, such as metabolic diseases and weakened immune systems, increase the vulnerability of patients to opportunistic infections. The increasing antibiotic resistance adds significant complexity to the management of infectious diseases. Although commensals have long been considered beneficial, recent research contradicts this notion by uncovering chronic illnesses linked to atypical pathogens or commensal bacteria. This review examines conditions in which commensal bacteria, which are usually beneficial, contribute to developing diseases. Commensals' support for opportunistic infections can be categorized based on factors such as colonization fitness, pathoadaptive mutation, and evasion of host immune response. Individuals with weakened immune systems are especially susceptible, highlighting the importance of mucosal host-microbiota interaction in promoting infection when conditions are inappropriate. Dysregulation of gut microbial homeostasis, immunological modulation, and microbial interactions are caused by several factors that contribute to the development of chronic illnesses. Knowledge about these mechanisms is essential for developing preventive measures, particularly for susceptible populations, and emphasizes the importance of maintaining a balanced gut microbiota in reducing the impact of opportunistic infections.

[PMID: 38440589 PMCID: PMC10908717 DOI: 10.1007/s12070-023-04321-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 10/23/2023] [Indexed: 03/06/2024] Open
Abstract
Aims To know the microorganism causing rhinosinusitis & to study the antibiotic sensitivity pattern for the isolated nasal microbiota in this region. Background Rhinosinusitis is inflammatory condition of nose and paranasal sinuses [1]. It is multifactorial condition, in which microorganisms play pathogenic role [2]. Interactions between microorganisms, mucosa and environmental changes influence on composition of bacterial ecosystem [2]. Though antibiotics are frequently used for medical management of rhinosinusitis, sensitivity directed antibiotics are rarely prescribed. So, this study is directed to know microbial isolate in rhinosinusitis and its antibiotic sensitivity pattern. Methodology in this 6 months prospective study during March to September 2022, done at Department of Otorhinolaryngology, Raichur Institute of Medical Sciences, Raichur; patients attending Otorhinolaryngology outpatient department and diagnosed to have rhinosinusitis were selected. Nasal swabs were collected from the middle meatus by diagnostic nasal endoscopy and were sent for culture and sensitivity. Statistical tests were applied for results(Size = 100). Results Out of 100 patients, 52 were males, 48 were females; 88 were adults & 12 were paediatric patients. 59 patients had acute, 32 chronic and 9 had recurrent rhinosinusitis. Most common organisms isolated in acute rhinosinusitis was Klebsiella 28%, Staphylococcus aureus 56% & 66% in chronic & recurrent rhinosinusitis respectively. Klebsiella was sensitive to beta lactams & quinolones, while Staphylococcus aureus was sensitive to beta lactams & cephalosporins. Conclusion Increase in antibiotic use has led to antibiotic resistance. Hence judicious, sensitivity directed antibiotic usage reduces the risk of antibiotic resistance and unnecessary use of antibiotics.

Comput Biol Med 2023; 167:107693. [PMID: 37976818 DOI: 10.1016/j.compbiomed.2023.107693] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 10/24/2023] [Accepted: 11/06/2023] [Indexed: 11/19/2023]
Abstract
Sinusitis is one of the most common respiratory inflammatory conditions and a significant health issue that affects millions of people worldwide with a global prevalence of 10-15%. The side effects of available drug regimens of sinus infection demand the urgent development of new drug candidates to combat sinusitis. With the aim of identifying new drug-like candidates to control sinus, we have conducted multifold comprehensive screening of drug-like molecules targeting α2-adrenergic receptor (α2-AR), which serve as the primary drug target in sinusitis. By structure-based virtual screening of in-house compound's database, ten molecules (CP1-CP10) with agonistic effects for α2-AR were selected, and their binding mechanism with critical residues of α2-AR and their physicochemical properties were studied. Moreover, the process of receptor activation by these compounds and the conformational changes in α2-AR caused by these molecules, were further explored by molecular dynamic simulation. The MM-PBSA estimated free energies of compounds are higher than that of reference agonist (ΔGTOTAL = -39.0 kcal/mol). Among all, CP2-CP3, CP7-CP8 and CP6 have the highest binding free energies of -78.9 kcal/mol, -77.3 kcal/mol, -75.60 kcal/mol, -64.8 kcal/mol, and -61.6 kcal/mol, respectively. While CP4 (-55.0 kcal/mol), CP5 (-49.2 kcal/mol), CP9 (-54.8 ± 0.07 kcal/mol), CP10 (-56.7 ± 0.10 kcal/mol) and CP1 (-46.0 ± 0.08 kcal/mol) also exhibited significant binding free energies. These energetically favorable binding energies indicate strong binding affinity of our compounds for α2-AR as compared to known partial agonist. Therefore, these molecules can serve as excellent drug-like candidates for sinusitis.

Effect of an Intranasal Corticosteroid on Quality of Life and Local Microbiome in Young Children With Chronic Rhinosinusitis: A Randomized Clinical Trial. JAMA Pediatr 2023; 177:345-352. [PMID: 36848113 PMCID: PMC9972242 DOI: 10.1001/jamapediatrics.2022.6172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 12/14/2022] [Indexed: 03/01/2023]
Abstract
Importance Intranasal corticosteroids (INCs) remain the first-line treatment of chronic rhinosinusitis (CRS) in both adults and children, despite the lack of evidence regarding their efficacy in the pediatric population. Similarly, their effect on the sinonasal microbiome has not been well documented. Objective To assess the clinical, immunological, and microbiological effects of 12 weeks of an INC in young children with CRS. Design, Setting, and Participants This open-label randomized clinical trial was performed in a pediatric allergy outpatient clinic in 2017 and 2018. Children aged 4 to 8 years with CRS diagnosed by a specialist were included. Data were analyzed from January 2022 to June 2022. Interventions Patients were randomized to receive intranasal mometasone in an atomizer for 12 weeks (1 application per nostril, once per day) and supplemental 3-mL sodium chloride (NaCl), 0.9%, solution in a nasal nebulizer once a day for 12 weeks (INC group) or 3-mL NaCl, 0.9%, solution in a nasal nebulizer once a day for 12 weeks (control group). Main Outcomes and Measures Measures taken both before and after treatment included the Sinus and Nasal Quality of Life Survey (SN-5), a nasopharynx swab for microbiome analysis by next-generation sequencing methods, and nasal mucosa sampling for occurrence of innate lymphoid cells (ILCs). Results Of the 66 children enrolled, 63 completed the study. The mean (SD) age of the cohort was 6.1 (1.3) years; 38 participants (60.3%) were male and 25 (39.7%) were female. The clinical improvement reflected by reduction in SN-5 score was significantly higher in the INC group compared with the control group (INC group score before and after treatment, 3.6 and 3.1, respectively; control group score before and after treatment, 3.4 and 3.8, respectively; mean between-group difference, -0.58; 95% CI, -1.31 to -0.19; P = .009). The INC group had a greater increase in nasopharyngeal microbiome richness and larger decrease in nasal ILC3 abundance compared with the control group. A significant interaction was observed between change in microbiome richness and the INC intervention on the prediction of significant clinical improvement (odds ratio, 1.09; 95% CI, 1.01-1.19; P = .03). Conclusions and Relevance This randomized clinical trial demonstrated that treatment with an INC improved the quality of life of children with CRS and had a significant effect on increasing sinonasal biodiversity. Although further investigation is needed of the long-term efficacy and safety of INCs, these data may reinforce the recommendation of using INCs as a first-line treatment of CRS in children. Trial Registration ClinicalTrials.gov Identifier: NCT03011632.

Abstract
Hyaluronic acid has been increasingly involved in recent research due to its many chemical and physical properties. This is a review of the literature for studies involving the use of hyaluronic acid in rhinology. Hyaluronic acid washes and irrigation have been increasingly used in chronic sinusitis medical therapy and post-operatively with mixed results. It has also been shown to play a role in the treatment of nasal polyposis, allergic rhinitis, acute rhinosinusitis and empty nose syndrome. Its effect on biofilm in many disease entities has also been studied. HA is being recently used as ancillary treatment for several rhinologic conditions such as post-operative endoscopy care and chronic sinonasal infections. The properties of HA have intrigued researchers over the past years particularly in biofilm management, healing and inflammation.

The difference in pathogenic bacteria between chronic rhinosinusitis in patients with and without Sjogren's syndrome: a retrospective case-control study. BMC Infect Dis 2022; 22:666. [PMID: 35915401 PMCID: PMC9344658 DOI: 10.1186/s12879-022-07652-4] [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: 05/15/2022] [Accepted: 07/27/2022] [Indexed: 11/11/2022] Open
Abstract
Background Chronic rhinosinusitis (CRS) affects the quality of life of many people worldwide and can cause comorbidities. Our previous research proved that Sjogren’s syndrome (SS) is a predisposing factor for CRS, with a 2.5-fold associated risk. Antibiotics are important in CRS treatment; however, there is a paucity of research on the pathogenic bacteria of SS-CRS in the past. We conducted this study to investigate the pathogenic difference of SS-CRS and non-SS-CRS and aimed to give clinicians references when selecting antibiotics to treat SS-CRS. Materials and methods A total of 14,678 patients hospitalized for CRS operation from 2004 to 2018 were identified from the Chang Gung Research Database. These CRS cases were classified as either SS-CRS or non-SS-CRS. We analyzed their bacterial distribution by studying the results of the pus cultures performed alongside surgery. Results The top three facultative anaerobic or aerobic isolated bacteria in the SS-CRS group were coagulase-negative Staphylococcus (CoNS: 34.3%), Pseudomonas aeruginosa (28.6%), methicillin-sensitive Staphylococcus aureus (MSSA: 20%), and Staphylococcus epidermidis (20%). In the non-SS-CRS group, S. epidermidis (29.3%), CoNS (25.7%), and MSSA (14.2%) were identified. The top three anaerobic bacterial genera were Cutibacterium (54.3%), Peptostreptococcus (11.4%), and Fusobacterium (11.4%) in the SS-CRS group and Cutibacterium (53.8%), Peptostreptococcus (25%), and Prevotella (12.9%) in the non-SS-CRS group. Conclusions P.aeruginosa is a major pathogen in SS-CRS patients. In addition, physicians should be aware of potential Fusobacterium and antibiotic-resistant bacterial infection in patients with SS-CRS.

Abstract
Chronic rhinosinusitis (CRS) is a significant health problem. It affects 5–12% of the general population. The causes that underlie the onset of CRS are not yet well known. However, many factors may contribute to its onset, such as environmental factors and the host’s general condition. Medical treatment mainly uses local corticosteroids, nasal irrigation, and antibiotics. In recent years, a new therapeutic approach that employs the use of probiotics emerged. Probiotics have been extensively studied as a therapy for dysbiosis and inflammatory pathologies of various parts of the body. We aimed to examine the studies in vivo and in vitro and clinicals reports in the existing literature to update probiotics’ role in rhinosinusitis chronic medical treatment.

Abstract
Malassezia are a lipid-dependent basidiomycetous yeast of the normal skin microbiome, although Malassezia DNA has been recently detected in other body sites and has been associated with certain chronic human diseases. This new perspective raises many questions. Are these yeasts truly present in the investigated body site or were they contaminated by other body sites, adjacent or not? Does this DNA contamination come from living or dead yeast? If these yeasts are alive, do they belong to the resident mycobiota or are they transient colonizers which are not permanently established within these niches? Finally, are these yeasts associated with certain chronic diseases or not? In an attempt to shed light on this knowledge gap, we critically reviewed the 31 published studies focusing on the association of Malassezia spp. with chronic human diseases, including psoriasis, atopic dermatitis (AD), chronic rhinosinusitis (CRS), asthma, cystic fibrosis (CF), HIV infection, inflammatory bowel disease (IBD), colorectal cancer (CRC), and neurodegenerative diseases.

Abstract
Chronic rhinosinusitis (CRS) is widely prevalent within the population and often leads to decreased quality of life, among other related health complications. CRS has classically been stratified by the presence of nasal polyps (CRSwNP) or the absence nasal polyps (CRSsNP). Management of these conditions remains a challenge as investigators continue to uncover potential etiologies and therapeutic targets. Recently, attention has been given to the sinunasal microbiota as both an inciting and protective influence of CRS development. The healthy sinunasal microbiologic environment is largely composed of bacteria, with the most frequent strains including Staphylococcus aureus, Streptococcus epidermidis, and Corynebacterium genera. Disruptions in this milieu, particularly increases in S. aureus concentration, have been hypothesized to perpetuate both Th1 and Th2 inflammatory changes within the nasal mucosa, leading to CRS exacerbation and potential polyp formation. Other contributors to the sinunasal microbiota include fungi, viruses, and bacteriophages which may directly contribute to underlying inflammation or impact bacterial prevalence. Modifiable risk factors, such as smoking, have also been linked to microbiota alterations. Research interest in CRS continues to expand, and thus the goal of this review is to provide clinicians and investigators alike with a current discussion on the microbiologic influence on CRS development, particularly with respect to the expression of various phenotypes. Although this subject is rapidly evolving, a greater understanding of these potential factors may lead to novel research and targeted therapies for this often difficult to treat condition.

Abstract
Upper respiratory tract infections include inflammations of the nose, sinuses (sinusitis), pharynx (tonsillitis, pharyngitis) and larynx (laryngitis) with bacteria or viruses as the main cause of these conditions. Due to their repetitive nature, chronic respiratory infections represent a global problem which is often a result of improper treatment. If not treated adequately, these conditions may have serious consequences. On the other hand, mis - and overuse of antibiotics has reduced their efficiency and accelerated the development of resistant bacterial strains, which further complicates the treatment of infections. This literature review will focus on current knowledge regarding medicinal plants and mushrooms which have been traditionally used in the treatment of infections caused by chronic sinusitis and tonsillitis commonly linked to bacteria - Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Fusobacterium nucleatum, Haemophilus influenzae and Moraxella catarrhalis. The present literature overview might be considered as a starting point for the development of novel, natural antimicrobial products with potential practical use in the treatment of chronic tonsillitis and sinusitis.

Abstract
The review presents the current understanding of the pathogenesis of chronic rhinosinusitis. The causes of damage to the mucous membrane of the paranasal sinuses are most often the result of a combination of immunological, infectious and anatomical factors. This indicates the need for a multidisciplinary approach to the study of the pathogenesis of this pathology. There is no single universally recognized classification of chronic rhinosinusitis, which takes into account histological and immunological changes in the mucous membrane of the paranasal sinuses. The discovery of the mechanism of completion of the life cycle of neutrophils - the formation of a neutrophil extracellular trap or NETosis, different from necrosis and apoptosis, opened up new prospects in the study of the pathogenesis of inflammatory processes, including rhinosinusitis. Neutrophil extracellular traps reduce the permeability of the epithelial barrier in the mucous membrane of the paranasal sinuses. This determines their possible role in the etiopathogenesis of rhinosinusitis. In recent years, more and more attention has been paid to the feasibility, effectiveness and safety of therapy that affects the immune component of the inflammatory process, including NETosis. The data obtained in the study of extracellular traps can be used in clinical practice. It is neutrophil extracellular traps that can become a potential target in the treatment of patients with chronic rhinosinusitis.

Exp Mol Med 2020; 52:978-987. [PMID: 32595207 PMCID: PMC7338545 DOI: 10.1038/s12276-020-0458-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 04/10/2020] [Accepted: 04/15/2020] [Indexed: 12/14/2022] Open
Abstract
Dysbiosis of the sinus microbiome affects the pathophysiology of chronic rhinosinusitis with nasal polyps (CRSwNPs). We investigated whether the sinus microbiota in CRSwNPs is associated with eosinophilic inflammation, especially in relation to innate lymphoid cells (ILCs), prognosis, and serum extracellular vesicles (EVs). Middle meatal swabs and serum from 31 CRSwNPs patients and six healthy controls were analyzed by 16S ribosomal RNA sequencing. ILC2s and cytokines from sinonasal tissues were measured by flow cytometry and ELISA, respectively. The relative abundances (RAs) of bacteria were compared based on eosinophilic inflammation and surgical outcome. The correlations between sinus bacteria and ILC2s, cytokines, and serum EVs were analyzed. The compositions of sinus bacteria were different between groups at the genus level. In eosinophilic CRSwNPs patients, the RA of Anaerococcus was significantly decreased (P = 0.010), whereas that of Lachnoclostridium was significantly increased (P = 0.038) compared with that in controls. The RA of Lachnoclostridium showed a significant positive correlation with interleukin (IL)-5-producing ILC2 populations (R = 0.340, P = 0.049), whereas the RA of Anaerococcus showed a negative correlation with IL-5-producing ILC2 populations (R = −0.332, P = 0.055). The RAs of Corynebacterium, Anaerococcus, and Tepidimonas were significantly decreased in patients with suboptimal outcomes compared with those in patients with optimal outcomes and control subjects. Some sinus bacteria and serum EVs showed positive correlations. CRSwNPs patients showed distinct microbiota compositions based on eosinophilic inflammation in relation to ILC2s and surgical outcome. These findings support a relationship between the microbiota and the host immune response in CRSwNPs. Microbes living in the sinonasal cavity seem to affect the immune responses and clinical outcomes of patients with an inflammatory disease that can cause lasting pain, pressure, and swelling in the sinuses. Ji Heui Kim from the Asan Medical Center in Seoul, South Korea, and colleagues collected nasal swabs and blood from 31 people suffering from chronic rhinosinusitis with nasal polyps and from six healthy control individuals. They identified several specific bacterial groups whose presence or absence was associated with the abundance of certain white blood cell populations, a sign of inflammation. Some of these groups were linked to patient outcomes after nasal surgery but additional groups were also observed. The findings could help lead to new treatment strategies or diagnostic biomarkers for patients with this sinus disorder.

Clinical Detection of Chronic Rhinosinusitis through Next-Generation Sequencing of the Oral Microbiota. Microorganisms 2020; 8:microorganisms8060959.

Abstract
Chronic rhinosinusitis (CRS) is the chronic inflammation of the sinus cavities of the upper respiratory tract, which can be caused by a disrupted microbiome. However, the role of the oral microbiome in CRS is not well understood. Polymicrobial and anaerobic infections of CRS frequently increased the difficulty of cultured and antibiotic therapy. This study aimed to elucidate the patterns and clinical feasibility of the oral microbiome in CRS diagnosis. Matched saliva and nasal swabs were collected from 18 CRS patients and 37 saliva specimens from normal volunteers were collected for 16S rRNA sequencing. The α-diversity of the saliva displayed no significant difference between control and CRS patients, whereas the β-diversity was significantly different (p = 0.004). Taxonomic indices demonstrated that Veillonella dispar, Rothia mucilaginosa, and Porphyromonas endodontalis were enriched, while Campylobacter and Cardiobacterium were reduced in the saliva of CRS patients. These microbial markers could significantly distinguish CRS patients from control (AUC = 0.939). It is noted that the 16S rRNA results of the nasal swab were consistent with the nasopharynx aerobic culture, and additionally detected multiple pathogens in CRS patients. In summary, these results indicated these oral microbiomes may provide a novel signal for CRS detection and that NGS may be an alternative approach for CRS diagnosis.

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
Background We developed and validated an artificial intelligence (AI)-assisted prediction of preeclampsia applied to a nationwide health insurance dataset in Indonesia. Methods The BPJS Kesehatan dataset have been preprocessed using a nested case-control design into preeclampsia/eclampsia (n = 3318) and normotensive pregnant women (n = 19,883) from all women with one pregnancy. The dataset provided 95 features consisting of demographic variables and medical histories started from 24 months to event and ended by delivery as the event. Six algorithms were compared by area under the receiver operating characteristics curve (AUROC) with a subgroup analysis by time to the event. We compared our model to similar prediction models from systematically reviewed studies. In addition, we conducted a text mining analysis based on natural language processing techniques to interpret our modeling results. Findings The best model consisted of 17 predictors extracted by a random forest algorithm. Nine∼12 months to the event was the period that had the best AUROC in external validation by either geographical (0.88, 95% confidence interval (CI) 0.88–0.89) or temporal split (0.86, 95% CI 0.85–0.86). We compared this model to prediction models in seven studies from 869 records in PUBMED, EMBASE, and SCOPUS. This model outperformed the previous models in terms of the precision, sensitivity, and specificity in all validation sets. Interpretation Our low-cost model improved preliminary prediction to decide pregnant women that will be predicted by the models with high specificity and advanced predictors.

Abstract
Chronic rhinosinusitis (CRS) is persistent inflammation and/or infection of the nasal cavity and paranasal sinuses. Recent advancements in culture-independent molecular techniques have enhanced understanding of interactions between sinus microbiota and upper airway microenvironment. The dysbiosis hypothesis-alteration of microbiota associated with perturbation of the local ecological landscape-is suggested as a mechanism involved in CRS pathogenesis. This review discusses the complex role of the microbiota in health and in CRS and considerations in sinus microbiome investigation, dysbiosis of sinus microbiota in CRS, microbial interactions in CRS, and development of preclinical models. The authors conclude with future directions for CRS-associated microbiome research.

Abstract
All nontechnical factors were analyzed to predict nasal bacterial culture results in patients with chronic rhinosinusitis (CRS). Four hundred and ninety-six CRS patients, who underwent functional endoscopic sinus surgery (FESS), were enrolled. Prior to FESS, the severity of each patient's CRS was evaluated using a questionnaire, endoscopic examination, acoustic rhinometry, smell test, saccharine transit test, and CT scan. Nasal bacterial cultures were collected from both middle meati using a cotton-tipped stick. Our results showed that the symptom severity complained of by patients and their loss of smell function did not influence the bacterial culture rate. We discovered that the bacterial culture rate was significantly higher in nostrils with nasal polyps than those without polyps, along with nostrils experiencing thick, purulent discharge as opposed to those without discharge. Additionally, this result also occurred in nostrils with a saccharin transit time of more than 30 min than it did in those with a saccharin transit time of less than or equal to 30 min. Both the total endoscopic score and anterior group CT score were significantly higher in nostrils with positive culture than those with negative culture, while the second minimal cross-sectional area (MCA2) of the nasal cavity was significantly lower in nostrils with positive culture than those with negative culture. Multiple logistic regression analysis showed that both nasal polyps and MCA2 were the predictors for positive nasal bacterial culture results. It was concluded that nasal polyps and MCA2 were the predictors for positive nasal bacterial culture results in CRS patients.

Abstract
Background: Acute exacerbations of chronic rhinosinusitis (CRS) have been increasingly recognized as an important disease entity with a significant impact on the quality of life. There is a growing amount of research on the etiopathogenesis and management of acute exacerbations of CRS. This review aims to summarize the current literature and provide an overall understanding of acute CRS exacerbations. Methods: A related literature review with the key terms of “chronic rhinosinusitis” and “exacerbation” was performed using PubMed. Results: There is no consensus definition of the acute exacerbation of CRS. Impaired mucociliary clearance, atrophic rhinitis, and immunologic changes are important predisposing factors for acute CRS exacerbations. Current evidence supports the role of the transient viral infection as the initial inflammatory stimulus in the pathogenesis of acute CRS exacerbations. Secondary bacterial infection or microbial community dysbiosis within the sinonasal cavity is the main event during the acute exacerbation of CRS. Distinct changes in local and systemic immune responses during exacerbation provide new insights into the pathophysiology of CRS exacerbation. Although current guidelines suggest the use of short-term antibiotics in patients with acute CRS exacerbation for symptomatic relief, evidence-based treatment recommendations for acute CRS exacerbation are still lacking, and large-high-quality RCTs are required. Conclusion: There have been significant advances in understanding the etiology and immunological feathers of acute CRS exacerbation. Nevertheless, consensus definition, diagnostic criterion, biomarkers to differentiate acute CRS exacerbation from CRS, assessment of disease severity, and evidence-based treatment options for acute CRS exacerbation are still lacking.

Abstract
This study aimed to identify trends in bacteria isolated from Korean adults with chronic rhinosinusitis (CRS). Enrolled were CRS patients who underwent sinus bacterial culture during endoscopic sinus surgery between 2007–2008, 2011–2012, and 2017–2018 (n = 510). Patients’ clinical characteristics, bacterial culture results, and antibiotic resistance were reviewed. The bacteria isolation rate was 76.3% (73.9% for CRS with nasal polyps and 82.8% for CRS without nasal polyps; p = 0.038). In total, 650 strains were isolated, the most common was Coagulase Negative Staphylococci (CNS) (28.0%), followed by Streptococcus species (12.2%), Propionibacterium species (8.0%), Corynebacterium species (7.5%), Staphylococcus aureus (6.2%), Haemophilus species (5.7%), Klebsiella species (5.1%), and Pseudomonas aeruginosa (4.2%). Furthermore, an analysis of the bacterial trends in the three groups showed significant increases over time for the isolation of CNS (p = 0.006), Klebsiella (p = 0.002), and P. aeruginosa (p = 0.007) and extended-spectrum beta-lactamase (ESBL) producing Klebsiella (p < 0.001) and Enterobacter (p = 0.007) species in terms of antibiotics resistance. This study demonstrates that the frequency of CNS, Klebsiella, and P. aeruginosa in CRS patients and the ESBL-producing Klebsiella and Enterobacter species has significantly increased in CRS patients over the last decade.
