Rhinitis Disease Burden and the Impact of Social Determinants of Health.

Social determinants of health (SDHs) have a substantial impact on patient care and outcomes globally, both in low- to middle-income countries and in high-income countries. In the clinic, lack of availability of diagnostic tools, inequities in access to care, and challenges obtaining and adhering to prescribed treatment plans may further compound these issues. This article addresses a case of rhinitis in the context of SDHs and inequities in care that may affect various communities and populations around the world. SDHs may include various aspects of one's financial means, education, access to medical care, environment and living situation, and community factors, each of which could play a role in the rhinitis disease manifestations, diagnosis, and management. Allergic and nonallergic rhinitis are considered from this perspective. Rhinitis epidemiology, disease burden, and risk factors are broadly addressed. Patient evaluation, diagnostic tests, and management options are also reviewed, and issues related to SDHs are noted. Finally, inequities in care, knowledge gaps, and unmet needs are highlighted. It is critical to consider SDHs and care inequities when evaluating and treating patients for rhinitis and other allergic conditions.

Optimizing the timing of biologic and surgical therapy for patients with refractory chronic rhinosinusitis with nasal polyposis (CRSwNP).

INTRODUCTION: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is often treated with endoscopic sinus surgery (ESS); however, patients may require revision surgery due to recurrence. To date, no studies have compared outcomes for combined surgery and biologic therapy for CRSwNP compared with biologic therapy alone. METHODS: Retrospective case-control study of CRSwNP patients who underwent ESS while on dupilumab or mepolizumab (ESS-biologic cohort) compared with CRSwNP patients on biologic therapy (biologic-only controls). Cohorts were matched according to indication, aspirin-exacerbated respiratory disease (AERD), sinonasal outcome test-22 (SNOT-22), and total polyp scores. RESULTS: Sixteen patients underwent ESS while on biologic therapy (13 dupilumab and 3 mepolizumab). Sixteen patients were biologic-only controls. There were no significant differences between indication, baseline SNOT-22 scores, polyp scores, and AERD status between cohorts. Patients underwent surgery a median of 33 days after starting biologic therapy. After 12 months of follow-up, the total polyp score for the ESS-biologic cohort decreased from 4.73 to 0.09 compared with a decrease from 5.22 to 3.38 for the biologic-only controls (95% confidence interval [CI] of difference: -5.37 to -1.38, Cohen's d: 2.40, p = 0.005). In the ESS-dupilumab subanalysis, the ESS-dupilumab cohort had a significant reduction in polyp burden from 4.85 to 0.00 compared with 4.88 to 3.50 for the controls (95% CI of difference: -5.68 to -1.32, Cohen's d: -1.69, p = 0.009). CONCLUSION: In CRSwNP patients, combined ESS and biologic therapy results in a significant and sustained decrease in polyp burden compared with biologic therapy alone. Larger studies are warranted to further examine the impact of combined therapy.

Allergic Rhinitis, Rhinosinusitis, and Asthma: Connections Across the Unified Airway.

The upper and lower airways are referred to as a single, integrated entity in the unified airway paradigm. When an allergen exposure occurs, the body responds locally and systemically, causing inflammation in other respiratory sites. As a result, asthmatic lower airway inflammation frequently coexists with upper airway inflammation, such as allergic rhinitis. Otolaryngologists are in a unique position to detect undiagnosed lower airway illness, start the proper therapy, and improve patient outcomes since they regularly encounter patients with upper airway problems.

Benefits of Immunoglobulin (Ig) Replacement Therapy for Primary and Secondary Immunodeficiency in Chronic Rhinosinusitis.

This is the first study to examine chronic rhinosinusitis (CRS) outcomes after starting immunoglobulin (Ig) replacement therapy for patients with primary (PID) and secondary immunodeficiency (SID). This is a retrospective review of patients diagnosed with CRS from 2018 to 2022 prior to initiating Ig therapy for the treatment of PID or SID. Outcomes included medication use and Sinonasal Outcome Test (SNOT-22) scores. Ten patients met the inclusion criteria. PID and SID patients had a decrease in antibiotics (PID: 9.40 to 3.20, P = .05, SID: 8.20 to 2.00, P = .04) and steroids (PID: (5.40 to 0.60; P = .06; SID: 2.20 to 0.20, P = .047) prescribed in the year after Ig compared to the year prior. Patients with SID had a decrease in mean SNOT-22 scores by 12 months after Ig (47.50 to 20.50, P = 0.03). Patients receiving Ig for PID and SID showed decreased medication use and SID patients experienced subjective improvement in CRS symptoms in year-over-year comparison.

Association Between SARS-CoV-2 Variants and Frequency of Acute Symptoms: Analysis of a Multi-institutional Prospective Cohort Study-December 20, 2020-June 20, 2022.

Background: While prior work examining severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern focused on hospitalization and death, less is known about differences in clinical presentation. We compared the prevalence of acute symptoms across pre-Delta, Delta, and Omicron. Methods: We conducted an analysis of the Innovative Support for Patients with SARS-CoV-2 Infections Registry (INSPIRE), a cohort study enrolling symptomatic SARS-CoV-2-positive participants. We determined the association between the pre-Delta, Delta, and Omicron time periods and the prevalence of 21 coronavirus disease 2019 (COVID-19) acute symptoms. Results: We enrolled 4113 participants from December 2020 to June 2022. Pre-Delta vs Delta vs Omicron participants had increasing sore throat (40.9%, 54.6%, 70.6%; P < .001), cough (50.9%, 63.3%, 66.7%; P < .001), and runny noses (48.9%, 71.3%, 72.9%; P < .001). We observed reductions during Omicron in chest pain (31.1%, 24.2%, 20.9%; P < .001), shortness of breath (42.7%, 29.5%, 27.5%; P < .001), loss of taste (47.1%, 61.8%, 19.2%; P < .001), and loss of smell (47.5%, 55.6%, 20.0%; P < .001). After adjustment, those infected during Omicron had significantly higher odds of sore throat vs pre-Delta (odds ratio [OR], 2.76; 95% CI, 2.26-3.35) and Delta (OR, 1.96; 95% CI, 1.69-2.28). Conclusions: Participants infected during Omicron were more likely to report symptoms of common respiratory viruses, such as sore throat, and less likely to report loss of smell and taste. Trial registration: NCT04610515.

Evaluation and treatment of rhinosinusitis with primary antibody deficiency in adults: Evidence-based review with recommendations.

BACKGROUND: There is clear evidence that the prevalence of primary antibody deficiency (PAD) is higher in patients with recurrent and chronic rhinosinusitis (CRS) than in the general population. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on rhinosinusitis with PAD, summarize the existing evidence, and provide recommendations on the evaluation and management of rhinosinusitis in patients with PAD. METHODS: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through August 2022. Studies on the evaluation and management of rhinosinusitis in PAD patients were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on the evaluation and management principles for PAD were generated. RESULTS: A total of 42 studies were included in this evidence-based review. These studies were evaluated on incidence of PAD in rhinosinusitis patients, incidence of rhinosinusitis in PAD patients, and on the different treatment modalities used and their outcome. The aggregate quality of evidence was varied across reviewed domains. CONCLUSION: Based on the currently available evidence, PAD can occur in up to 50% of patients with recalcitrant CRS. Despite the presence of multiple studies addressing rhinosinusitis and PAD, the level of evidence supporting different treatment options continues to be lacking. Optimal management requires a multidisciplinary approach through collaboration with clinical immunology. There is need for higher-level studies that compare different treatments in patients with PAD and rhinosinusitis.

Multimodal Analgesia and Patient Education Reduce Postoperative Opioid Consumption in Otology.

OBJECTIVE: This study sought to validate alternative pain management strategies that can reduce reliance on opioids for postoperative pain management in otology. STUDY DESIGN: Prospective cohort study. SETTING: Single tertiary-care facility. METHODS: Adult patients who underwent outpatient otologic surgery from September 2021 to July 2022 were randomized into treatment cohorts. The opioid monotherapy cohort received a standard opioid prescription. The multimodal analgesia cohort received the same opioid prescription, prescriptions for acetaminophen and naproxen, and additional pain management education with a flyer on discharge. All patients completed a questionnaire 1 week after surgery to evaluate opioid usage and pain scores. RESULTS: Eighty-six patients completed the study. The opioid monotherapy cohort (n = 42) and multimodal analgesia cohort (n = 44) were prescribed an average of 42.1 ± 20.4 morphine milligram equivalents (MME) and 38.4 ± 5.7 MME, respectively (p = 0.373). Four patients (9.52%) in the opioid monotherapy cohort required opioid refills compared to 1 patient (2.27%) in the multimodal analgesia cohort (p = 0.156). Multivariate analysis demonstrated that the multimodal analgesia cohort consumed significantly fewer opioids on average than the opioid monotherapy cohort (11.9 ± 15.9 MME vs 22.8 ± 28.0 MME, respectively). There were no significant differences in postoperative rehospitalizations (p = 0.317) or Emergency Department visits (p = 0.150). Pain scores on the day of surgery, postoperative day (POD) 1, POD3, and POD7 were not significantly different between cohorts (p = 0.395, 0.896, 0.844, 0.765, respectively). CONCLUSION: The addition of patient education, acetaminophen, and naproxen to postoperative opioid prescriptions significantly reduced opioid consumption without affecting pain scores, refill rates, or complication rates after otologic surgery.

Severe Fatigue and Persistent Symptoms at 3 Months Following Severe Acute Respiratory Syndrome Coronavirus 2 Infections During the Pre-Delta, Delta, and Omicron Time Periods: A Multicenter Prospective Cohort Study.

BACKGROUND: Most research on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants focuses on initial symptomatology with limited longer-term data. We characterized prevalences of prolonged symptoms 3 months post-SARS-CoV-2 infection across 3 variant time-periods (pre-Delta, Delta, and Omicron). METHODS: This multicenter prospective cohort study of adults with acute illness tested for SARS-CoV-2 compared fatigue severity, fatigue symptoms, organ system-based symptoms, and ≥3 symptoms across variants among participants with a positive ("COVID-positive") or negative SARS-CoV-2 test ("COVID-negative") at 3 months after SARS-CoV-2 testing. Variant periods were defined by dates with ≥50% dominant strain. We performed multivariable logistic regression modeling to estimate independent effects of variants adjusting for sociodemographics, baseline health, and vaccine status. RESULTS: The study included 2402 COVID-positive and 821 COVID-negative participants. Among COVID-positives, 463 (19.3%) were pre-Delta, 1198 (49.9%) Delta, and 741 (30.8%) Omicron. The pre-Delta COVID-positive cohort exhibited more prolonged severe fatigue (16.7% vs 11.5% vs 12.3%; P = .017) and presence of ≥3 prolonged symptoms (28.4% vs 21.7% vs 16.0%; P < .001) compared with the Delta and Omicron cohorts. No differences were seen in the COVID-negatives across time-periods. In multivariable models adjusted for vaccination, severe fatigue and odds of having ≥3 symptoms were no longer significant across variants. CONCLUSIONS: Prolonged symptoms following SARS-CoV-2 infection were more common among participants infected during pre-Delta than with Delta and Omicron; however, these differences were no longer significant after adjusting for vaccination status, suggesting a beneficial effect of vaccination on risk of long-term symptoms.

Extensive Healthy Donor Age/Gender Adjustments and Propensity Score Matching Reveal Physiology of Multiple Sclerosis Through Immunophenotyping.

Quantifying cell subpopulations in biological fluids aids in diagnosis and understanding of the mechanisms of injury. Although much has been learned from cerebrospinal fluid (CSF) flow cytometry in neuroimmunological disorders, such as multiple sclerosis (MS), previous studies did not contain enough healthy donors (HD) to derive age- and gender-related normative data and sufficient heterogeneity of other inflammatory neurological disease (OIND) controls to identify MS specific changes. The goals of this blinded training and validation study of MS patients and embedded controls, representing 1,240 prospectively acquired paired CSF/blood samples from 588 subjects was (1) to define physiological age-/gender-related changes in CSF cells, (2) to define/validate cellular abnormalities in blood and CSF of untreated MS through disease duration (DD) and determine which are MS-specific, and (3) to compare effect(s) of low-efficacy (i.e., interferon-beta [IFN-beta] and glatiramer acetate [GA]) and high-efficacy drugs (i.e., natalizumab, daclizumab, and ocrelizumab) on MS-related cellular abnormalities using propensity score matching. Physiological gender differences are less pronounced in the CSF compared to blood, and age-related changes suggest decreased immunosurveillance of CNS by activated HLA-DR+T cells associated with natural aging. Results from patient samples support the concept of MS being immunologically single disease evolving in time. Initially, peripherally activated innate and adaptive immune cells migrate into CSF to form MS lesions. With progression, T cells (CD8+ > CD4+), NK cells, and myeloid dendritic cells are depleted from blood as they continue to accumulate, together with B cells, in the CSF and migrate to CNS tissue, forming compartmentalized inflammation. All MS drugs inhibit non-physiological accumulation of immune cells in the CSF. Although low-efficacy drugs tend to normalize it, high-efficacy drugs overshoot some aspects of CSF physiology, suggesting impairment of CNS immunosurveillance. Comparable inhibition of MS-related CSF abnormalities advocates changes within CNS parenchyma responsible for differences in drug efficacy on MS disability progression. Video summarizing all results may become useful educational tool.

Cisplatin induces neuronal activation and increases central AMPA and NMDA receptor subunit gene expression in mice.

Although rats and mice do not vomit, these species are widely studied as models of energy balance and sickness behavior. Previous work has shown that rats exhibit similar neuroanatomical activation of brain and visceral afferent pathways following cisplatin chemotherapy compared to vomiting species. However, the neural response to cisplatin in mice is understudied. Here, food intake, body weight, and central c-Fos immunofluorescence were analyzed in the hindbrains of male C57BL/6 mice following IP saline or cisplatin (5mg/kg, and 20mg/kg doses). As glutamate receptor signaling is classically linked to inhibitory feeding pathways in the rodent, gene expression of selected α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and N-methyl-d-aspartic acid (NMDA) receptor subunits were assessed in the dorsal vagal complex (DVC), parabrachial nucleus (PBN), amygdala, and bed nucleus of the stria terminalis (BNST). Our results show dose-dependent reductions in food intake and body weight following cisplatin treatment, as well as increases in cisplatin-induced c-Fos in the PBN and throughout the DVC. Quantitative PCR analysis shows cisplatin-induced increases in NMDA receptor subunit expression, particularly NR2B, in the DVC, PBN, BNST, and amygdala. In addition, upregulation of AMPA receptor subunits (GluA1 and/or GluA2) were observed in all regions examined except the amygdala. Taken together, these results suggest similar neural pathways mediating cisplatin effects in mice compared to other well-studied species, which are likely mediated by central upregulation of AMPA and NMDA receptors.
