Influence of Frailty Status on the Efficacy of Epidural Steroid Injections in Elderly Patients With Degenerative Lumbar Spinal Disease.

Background: The global increase in the elderly population has led to a higher prevalence of degenerative lumbar spinal diseases. Epidural steroid injection (ESI) is a widely used procedure for managing lower back pain. This study investigated the association of preprocedural frailty status with the efficacy of ESI in elderly patients diagnosed with degenerative lumbar spinal diseases. Methods: This retrospective observational study included patients aged 65 years and older who underwent lumbar ESI. Frailty status (robust, prefrail, and frail) assessed via the Frailty Phenotype Questionnaire was collected along with demographic and clinical parameters. Good analgesia was defined as a ≥ 50% reduction in pain score at 4-week follow-up evaluation. Multivariable logistic regression analyses were performed to identify factors associated with poor analgesia. Results: We included 289 patients in this study. Frailty status correlated with analgesic outcomes, with worsening frailty status correlating with increasingly poor analgesia after the injection (robust = 34.5%, prefrail = 40.8%, and frail = 60.0%, p=0.003), predominantly in female patients. After adjusting for demographic and clinical factors, frail patients demonstrated much higher odds of poor analgesia than robust individuals (adjusted odds ratio [aOR] = 2.673, 95% confidence interval [CI] = 1.338-5.342, p=0.005). Conversely, prefrail patients did not show a significant association with analgesic outcome (aOR = 1.293, 95% CI = 0.736-2.272, p=0.372). Conclusions: Frailty, but not prefrailty, appeared to be an independent factor associated with poor analgesic efficacy of ESI in elderly patients with symptomatic degenerative lumbar spinal disease receiving conservative care.

Prediction of transforaminal epidural injection success in sciatica (POTEISS): a protocol for the development of a multivariable prediction model for outcome after transforaminal epidural steroid injection in patients with lumbar radicular pain due to disc herniation or stenosis.

BACKGROUND: Transforaminal epidural injections (TEI) can alleviate symptoms and help to maintain physical functioning and quality of life in patients with lumbar radicular pain. We aim to develop a prediction model for patient outcome after TEI in patients suffering from unilateral lumbar radicular pain due to lumbar disc herniation (LDH) or single-level spinal stenosis (LSS). The secondary aim is to estimate short-term patient outcome differences between LDH and LSS patients, the association between psychological variables and patient outcome, the rate of additional injections, surgery and complications, and to explore the short-term cost-effectiveness of TEI. METHODS: This study is designed as a multi-centre, observational, prospective cohort study in two large regional hospitals in the Netherlands. Patients diagnosed with unilateral lumbar radicular pain secondary to LDH or LSS and congruent with MRI findings, who are referred for TEI along usual care pathways, are eligible for study participation. A total of 388 patients with LDH or LSS will be included. A pre-defined set of demographic, clinical and radiological variables will be used as the predictors in the model. The primary outcome measure is the Numerical Rating Scale (NRS) for leg pain. Secondary outcome measures include back pain, physical functioning, perceived recovery, pain coping strategies, anxiety and depression and use of analgesics and physical therapy. Patients will be evaluated at baseline, 2 weeks and 6 weeks after treatment. NRS leg pain and Likert perceived recovery data will be used as the dependent variables in a generalized linear mixed model for prediction of TEI outcome, with internal validation of performance (explained variation) by bootstrap resampling. Cost-effectiveness for a period of 6 weeks prior to and after treatment will be performed with decision-analytic modelling. DISCUSSION: Patients with severe lumbar radicular pain often request additional treatment when conservative care is insufficient. TEI can offer relief of symptoms. Currently, it is not possible to predict responsiveness to this treatment for individual patients. This study is designed to explore predictors that can differentiate between patients that will and will not have a positive outcome after TEI. This information may support treatment strategies for this patient group. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov database under registry number NCT04540068 on September 1, 2020.

Investigating Topical Steroid Withdrawal Videos on TikTok: Cross-Sectional Analysis of the Top 100 Videos.

BACKGROUND: Social media platforms like TikTok are a very popular source of information, especially for skin diseases. Topical steroid withdrawal (TSW) is a condition that is yet to be fully defined and understood. This did not stop the hashtag #topicalsteroidwithdrawal from amassing more than 600 million views on TikTok. It is of utmost importance to assess the quality and content of TikTok videos on TSW to prevent the spread of misinformation. OBJECTIVE: This study aims to assess the quality and content of the top 100 videos dedicated to the topic of TSW on TikTok. METHODS: This observational study assesses the content and quality of the top 100 videos about TSW on TikTok. A total of 3 independent scoring systems: DISCERN, Journal of the American Medical Association, and Global Quality Scale were used to assess the video quality. The content of the videos was coded by 2 reviewers and analyzed for recurrent themes and topics. RESULTS: This study found that only 10.0% (n=10) of the videos clearly defined what TSW is. Videos were predominantly posted by White, middle-aged, and female creators. Neither cause nor mechanism of the disease were described in the videos. The symptoms suggested itching, peeling, and dryness which resembled the symptoms of atopic dermatitis. The videos fail to mention important information regarding the use of steroids such as the reason it was initially prescribed, the name of the drug, concentration, mechanism of usage, and method of discontinuation. Management techniques varied from hydration methods approved for treatment of atopic dermatitis to treatment options without scientific evidence. Overall, the videos had immense reach with over 200 million views, 45 million likes, 90,000 comments, and 100,000 shares. Video quality was poor with an average DISCERN score of 1.63 (SD 0.56)/5. Video length, total view count, and views/day were all associated with increased quality, indicating that patients were interacting more with higher quality videos. However, videos were created exclusively by personal accounts, highlighting the absence of dermatologists on the platform to discuss this topic. CONCLUSIONS: The videos posted on TikTok are of low quality and lack pertinent information. The content is varied and not consistent. Health care professionals, including dermatologists and residents in the field, need to be more active on the topic, to spread proper information and prevent an increase in steroid phobia. Health care professionals are encouraged to ride the wave and produce high-quality videos discussing what is known about TSW to avoid the spread of misinformation.

Negative association of steroids with immunotherapy efficacy in a multi-tumor cohort: time and dose-dependent.

Previous studies have suggested a negative impact of steroids on the efficacy of immune checkpoint inhibitors (ICI), but how this effect is modulated by the dosage and time of administration is yet to be clarified. We have performed a retrospective analysis of 475 patients with advanced solid tumors treated with ICI as monotherapy from 2015 to 2022. Data regarding immune-related adverse events (irAEs) and clinical outcomes were collected. For each patient, the daily steroid dose (in mg/kg of prednisone) was registered until disease progression or death. The impact of cumulative doses on response rates and survival outcomes was analyzed within different periods. The objective response rate (ORR) was significantly lower among patients exposed to steroids within 30 days before the first cycle of ICI (C1) (20.3% vs. 36.7%, p < 0.01) and within the first 90 days of treatment (25.7% vs. 37.7%, p = 0.01). This negative association was confirmed by multivariable analysis. Higher mean steroid doses were observed among non-responders, and cumulative doses were inversely correlated with the disease control rate (DCR) around ICI initiation. Remarkably, poorer outcomes were observed even in patients belonging to the lowest dose quartile compared to the steroid-naïve population. The exposure to steroids after 6 months of ICI was not associated with worse survival outcomes. Our results suggest that the potential impact of steroids on ICI efficacy may be time-dependent, prevailing around ICI initiation, and dose-dependent, with modulation of neutrophil-to-lymphocyte ratio as a possible underlying mechanism.

Prophylactic antibiotics in patients with alcohol-associated hepatitis receiving steroids: A systematic review and meta-analysis.

BACKGROUND & AIMS: The benefits of prophylactic antibiotics in patients with alcohol-associated hepatitis (AH) receiving steroids remain unclear. We aimed to assess the clinical impact of prophylactic antibiotics in AH patients receiving steroids. METHODS: We systematically reviewed four electronic databases from inception to 30 November 2023. Pooled estimates were analysed using random-effects models. The primary outcome was 90-day survival. Secondary outcomes included infection at days 30 and 90 days, hepatorenal syndrome (HRS), acute kidney injury (AKI), hepatic encephalopathy (HE) and drug-related adverse events (AE). Trial sequential analyses were performed for the primary outcome of 90-day mortality. RESULTS: We screened 419 articles and included six eligible studies (four RCTs and two matched cohort studies) with a total of 510 patients. Compared to standard medical treatment (SMT), prophylactic antibiotics were associated with a lower risk of infection at 30 days (OR: 0.35, 95%CI: 0.20-0.59, I 2 = 0%), infection at 90 days (OR: 0.26, 95%CI: 0.10-0.67, I 2 = 0%) and a lower rate of HE (OR: 0.32, 95%CI: 0.12-0.87, I 2 = 0%). However, prophylactic antibiotics did not improve 90-day survival, sepsis-related mortality, HRS, or AKI. The risks of drug-related AE and fungal infections were similar in patients with AH who received prophylactic antibiotics or SMT. Using trial sequential analysis, the minimum sample size required to detect a 15% relative risk reduction in 90 days mortality with prophylactic antibiotics was 1171. CONCLUSIONS: In hospitalized AH patients receiving steroid therapy, prophylactic antibiotics reduced the risk of infection and HE, but did not improve survival or prevent AKI compared to SMT.

A rare cause of pelvic pain: Osteitis pubis treated with steroid injection under fluoroscopy guidance.

Osteitis pubis (OP) is a rare, inflammatory disorder that affects the pubic bone, symphysis, and adjacent structures. OP is reported after urological and gynecological surgeries and documented in athletes. OP is a self-limiting condition, but sometimes symptoms may persist for a long time. Conservative modalities are generally able to treat OP. Here we report a patient treated with a steroid injection under fluoroscopy guidance. A 63-year-old male patient developed pelvic pain after prostate surgery, and the pain was intractable to non-steroidal anti-inflammatory drugs. He underwent a steroid injection under fluoroscopy, and his pain affecting daily living activities and walking was eased for three months.

Effect of Chronic Steroid Use on Postoperative Wound Complications in Patients Undergoing Arterial Bypass Surgery for Lower Extremity Peripheral Arterial Disease.

BACKGROUND: While existing literature reports adverse effects of chronic steroid use on surgical wound outcomes, there remains lack of data exploring the effect of steroids on postoperative outcomes following lower extremity arterial bypass surgery. This study aims to explore the effect of chronic steroid use on surgical outcomes in patients undergoing open revascularization for lower extremity arterial occlusive disease. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) files between 2005 and 2020, all patients receiving aortoiliac or infrainguinal arterial bypass for peripheral arterial disease (PAD) were identified by Current Procedural Terminology (CPT) codes. Patient characteristics and 30-day outcomes were compared using χ2 test and independent t-test, and the association of chronic steroid use with wound complications was studied using multivariable logistic regression analysis. RESULTS: A total of 44,675 patients undergoing open lower extremity revascularization (LER) were identified, of which 1,807 patients were on chronic steroids, and 42,868 patients were not on chronic steroids. On multivariable logistic regression analysis, being on chronic steroids was associated with higher rates of deep surgical site infections (SSIs) (odds ratio [OR] 1.37, 95% confidence interval [CI] 1.03-1.83), any SSI (OR 1.22, 95% CI 1.04-1.43), and wound dehiscence (OR 1.42, 95% CI 1.03-1.96). Chronic steroid users also had significantly increased odds of developing sepsis (OR 1.56, 95% CI 1.19-2.04), pneumonia (OR 1.44, 95% CI 1.08-1.91), urinary tract infection (UTI) (OR 1.54, 95% CI 11.13-2.09), deep vein thrombosis (DVT) (OR 1.60, 95% CI 1.01-2.53), 30-day readmission (OR 1.30, 95% CI 1.12-1.50), reoperation (OR 1.17, 95% CI 1.01-1.37), and mortality (OR 1.33, 95% CI 1.01-1.76) compared with nonchronic steroid users. CONCLUSIONS: This study confirms that chronic corticosteroid use is associated with higher risk of SSIs in patients undergoing lower extremity arterial bypass surgery. These patients typically have various underlying health issues, emphasizing the need for personalized treatment and management to reduce steroid-related postoperative complications and improve survival.

Lumbar transforaminal epidural steroid injections with particulate vs. nonparticulate steroid: an evidence-informed review on shifting gear to a personalized medicine paradigm.

PURPOSE OF REVIEW: To provide an evidence-informed review weighing the pros and cons of particulate vs. nonparticulate steroids for lumbar transforaminal epidural steroid injections (TFESI). RECENT FINDINGS: The relative use of nonparticulate vs. particulate steroids for lumbar TFESI has risen recently in light of catastrophic consequences reported for the latter during cervical TFESI. Among various causes of spinal cord infarct, an exceedingly rare event in the lower lumbar spine, embolization of particulate steroid is among the least likely. Case reports have documented cases of spinal cord infarct during lower lumbar TFESI with both particulate and nonparticulate steroids, with database reviews finding no difference in complication rates. There is some evidence for superiority of particulate over nonparticulate steroids in well-designed studies, which could lead to increase steroid exposure (i.e. more injections) and treatment failure resulting in surgical and/or opioid management when nonparticulate steroids are utilized. SUMMARY: Similar to a paradigm shift in medicine, a personalized approach based on a shared decision model and the consequences of treatment failure, should be utilized in deciding which steroid to utilize. Alternatives to ESI include high-volume injections with nonsteroid solutions, and the use of hypertonic saline, which possesses anti-inflammatory properties and has been shown to be superior to isotonic saline in preliminary clinical studies.

Cerebral Venous Sinus Thrombosis After Lumbar Epidural Steroid Injection: A Case Report.

Cerebral venous sinus thrombosis (CVST) is an exceedingly rare complication of epidural anesthesia, with only a handful of known cases after epidural steroid injection (ESI). We report a case of CVST in a 33-year-old male patient that presented with headache after lumbar ESI. His clinical status initially improved on anticoagulation in the intensive care unit. However, he had a sudden worsening of cerebral edema that required an emergent hemicraniectomy. Ultimately, the patient was pronounced dead by neurologic criteria. This case highlights the importance of keeping this rare but potentially fatal diagnosis in the differential even in lower-risk patient populations.

Preoperative chronic steroid use as a risk factor for complications following open reduction internal fixation for proximal humerus fracture.

PURPOSE: The primary objective of this study was to investigate the association between preoperative chronic steroid use and postoperative complications following open reduction internal fixation (ORIF) for proximal humerus fractures (PHF). METHODS: The American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for all patients who underwent PHF ORIF between 2015 and 2021. A total of 6,273 patients were included in this study, of which 3.4% (n = 212) were in the chronic steroid use cohort. Patient characteristics including demographics, comorbidities, and 30-day postoperative complications after PHF ORIF were collected. Bivariate logistic regression and multivariate logistic regression analysis, adjusted for all significantly associated variables, was conducted to investigate the relationship between preoperative chronic steroid use and postoperative complications. RESULTS: Chronic steroid use was significantly associated with age ≥ 75 (p < 0.001), male gender (p =0.006), dependent functional status (p = 0.008), American Society of Anesthesiologist (ASA) ≥ 3 (p < 0.001), CHF (p = 0.007), hypertension (p < 0.001), COPD (p < 0.001), bleeding disorder (p = 0.007), ascites (p = 0.040), disseminated cancer (p< 0.001), and systemic sepsis (p < 0.001). After adjusting for all significantly associated variables, chronic steroid use was independently associated with major complication (OR 1.60, 95% CI 1.06-2.43; p = 0.026), and non-home discharge (OR 1.05, 95% CI 1.01-1.08; p = 0.014). CONCLUSION: Preoperative chronic steroid use is associated with increasing rate of postoperative complications following PHF ORIF. Better understanding and characterizing chronic steroid use as a preoperative risk factor can aid physicians in risk stratification to reduce rates of postoperative complications following PHF ORIF. LEVEL OF EVIDENCE: III. Retrospective Cohort Comparison; Prognosis Study.

New investigational drugs for steroid-refractory acute graft-versus-host disease: a review of the literature.

INTRODUCTION: Steroid-refractory acute graft-versus-host disease (SR-aGVHD) remains a formidable obstacle in the field of allogeneic hematopoietic cell transplantation (allo-HCT), significantly contributing to patient morbidity and mortality. The current therapeutic landscape for SR-aGVHD is limited, often yielding suboptimal results, thereby emphasizing the urgent need for innovative and effective treatments. AREAS COVERED: In light of the pivotal REACH2 trial, ruxolitinib phosphate, a Janus kinase inhibitor, has gained prominence as the standard treatment for SR-aGVHD. Nevertheless, a considerable number of patients either do not respond to or cannot tolerate this therapy. This review delves into emerging treatments for SR-aGVHD, including mesenchymal stromal cells (MSCs), fecal microbiota transplantation (FMT), CD3/CD7 blockade, neihulizumab, begelomab, tocilizumab, and vedolizumab. While some of these agents have shown encouraging results in early-phase trials, issues such as treatment-related toxicities and inconsistent responses in larger studies highlight the necessity for ongoing research. EXPERT OPINION: Current trials exploring new agents and combination therapies offer hope for fulfilling the unmet clinical needs in SR-aGVHD, potentially leading to more effective and precise treatment strategies.

Regression course of ostium granulomas under topical intranasal steroids coverage after endoscopic dacryocystorhinostomy.

This study aimed to elucidate the regression process of ostium granulomas under the usage of intranasal steroid after primary endoscopic dacryocystorhinostomy (DCR). The authors retrospectively reviewed 57 patients (a total of 72 ostia) who had ostium granulomas after primary endoscopic DCR between 2011 and 2015. Topical intranasal steroid spray was applied in all the patients since postoperative day 1. Adjunctive intralesional triamcinolone acetonide injections were administered for extensive and large-sized granulomas that caused impending ostium blockage. Sequential regression of the ostium granulomas and success rates of DCR were assessed using endoscopic photos. The granulomas completely disappeared in 69 (95.8%) ostia, and the average time interval from the surgery to the disappearance was 6.9 ± 2.8 months. Anatomical and functional surgical success rates were 90.3% and 84.7%, respectively. Intralesional steroid injections for ostium granulomas did not alter the outcomes compared to topical intranasal steroid usage significantly (p = 0.445). In conclusion, we observed that, by continuing the usage of intranasal steroids, ostium granulomas disappear gradually at postoperative 6 months. The intranasal surgical manipulation of granulomas, which results in more mucosal cicatricial change and impedes patient satisfaction, can be successfully avoided.

Comparison of Single Lumbar Transforaminal Epidural Steroid Injections for Treatment of Early and Late Recurrent Lumbar Disc Herniation.

AIM: To compare the results of fluoroscopically guided transforaminal epidural steroid injection (TESI) for pain reduction in ipsilateral early recurrent lumbar disc herniation (RLDH) with ipsilateral late RLDH. MATERIAL AND METHODS: A total of 738 patients complaining of radicular pain due to ipsilateral early and late RLDH were assessed. Of these, TESI was administered to 390 subjects for ipsilateral early RLDH and 346 for ipsilateral late RLDH. TESIs were performed based on radicular leg pain; all subjects were followed up and reexamined after 12 weeks of the therapy. Pre- and postprocedural visual analog scale (VAS) scores and all complications were recorded for the study. RESULTS: For radicular pain, the mean pre-, and postprocedural VAS scores for ipsilateral early RLDH were 85.44 ± 6.85 and 20.16 ± 3.77 respectively. For late RLDH, the mean pre-, and postprocedural VAS scores were 72.82 ± 5.12 and 30.87 ± 4.17, respectively. A significant statistical difference for pre- and postprocedural VAS scores were observed between ipsilateral early and late recurrent disc herniation TESI groups (p < 0.05). CONCLUSION: TESI was more effective for early RLDH than for late RLDH during the 12-week follow-up period.

Real-world incidences and risk factors of immune-related adverse events in patients treated with immune checkpoint inhibitors: A nationwide retrospective cohort study.

Immune-related adverse events (irAEs) caused by immune checkpoint inhibitors (ICIs) are rare but fatal, requiring systemic steroid use. Therefore, to examine the outcomes, incidence, timing, and risk factors of ICI-associated steroid-requiring severe irAEs, we conducted a nationwide, retrospective, cohort study utilizing the Korean Health Insurance and Review Assessment database. We identified 357,010 patients with lung cancer, bladder cancer, or skin melanoma, eligible for ICI reimbursement in Korea between January 2012 to June 2020. Steroid-requiring severe irAEs following ICI treatment or treatment-emergent AEs following cytotoxic chemotherapy were defined as moderate- or high-dose steroid administration for over 2 consecutive days, along with corresponding ICD-10 codes indicating affected organ systems. The ICI-exposed group (N = 10,118) was compared to a matched cohort of 55,436 ICI-unexposed patients treated with cytotoxic chemotherapy. Incidences of acute severe irAEs requiring moderate- and high-dose steroids were higher in the ICI-exposed group (1.95% and 6.42%, respectively). The ICI-exposed group also had a higher risk of developing delayed severe irAEs requiring moderate- and high-dose steroid use (3.89% and 7.39%). Male sex, high comorbidity index, or previously diagnosed autoimmune diseases were associated with an increased risk of severe irAEs. Notably, 27.4-38.8% of the patients experienced recurrent severe irAEs after re-challenge with ICIs following moderate- or high-dose steroid use, with the severity matching the initial episode. Steroid-requiring severe irAEs were significantly more prevalent among patients exposed to ICIs than among those treated with chemotherapy in acute and delayed periods.

Combined Ultrasound and Fluoroscopy versus Ultrasound versus Fluoroscopy-Guided Caudal Epidural Steroid Injection for the Treatment of Unilateral Lower Lumbar Radicular Pain: A Retrospective Comparative Study.

Background and Objectives: This study aimed to evaluate the mid-term effectiveness and safety of a combined ultrasound (US) and fluoroscopy (FL)-guided approach in comparison to US-guided and FL-guided caudal epidural steroid injections (CESI) for treating unilateral lower lumbar radicular pain. Materials and Methods: A total of 154 patients who underwent CESI between 2018 and 2022 were included. Patients were categorized into three groups based on the guidance method: combined US and FL (n = 51), US-guided (n = 51), and FL-guided (n = 52). The study design was retrospective case-controlled, utilizing patient charts and standardized forms to assess clinical outcomes, adverse events, complications during the procedures. Results: In all groups, Oswestry Disability Index and Verbal Numeric Scale scores improved at 1, 3, and 6 months after the last injection, with no significant differences between groups (p < 0.05). The treatment success rate at all time points was also similar among the groups. Logistic regression analysis showed that injection method, cause, sex, age, number of injections, and pain duration did not independently predict treatment success. Blood was aspirated before injection in 2% (n = 1), 13.5% (n = 7), and 4% (n = 2) of patients in the combined US and FL groups, FL-guided groups, and US-guided groups, respectively. Intravascular contrast spread was detected in one patient in the combined method groups and seven in the FL-guided groups. Conclusions: When comparing pain reduction and functional improvement, there was no significant difference between the three methods. The combined method took less time compared to using FL alone. The combined approach also showed a lower occurrence of intravascular injection compared to using FL alone. Moreover, blood vessels at the injection site can be identified with an ultrasound using the combined method. Given these advantages, it might be advisable to prioritize the combined US- and FL-guided therapy when administering CESI for patients with unilateral lumbar radicular pain.

Unintentional Injection Into the Retrodural Space of Okada During Transforaminal Epidural Steroid Injection.

BACKGROUND: Transforaminal epidural steroid injection (TFESI) is commonly used for radicular pain, but can lead to an unintentional injection into the retrodural Space of Okada (RSO), an extradural space located dorsal to the ligamentum flavum, instead of the epidural space. OBJECTIVES: To determine the prevalence and describe the fluoroscopic imaging features of an unintentional injection into the RSO during a TFESI and to review the history of injections into the RSO. STUDY DESIGN: Observational study and original research. SETTING: This work was conducted at Jeju National University School of Medicine, Jeju, Republic of Korea. METHODS: A total of 5,429 lumbar TFESIs performed from the September 1, 2018 through October 31, 2021 were analyzed for unintentional RSO injections using fluoroscopic-guided contrast medium patterns. RESULTS: The rate of unintentional injection into the RSO was 0.20% (11 incidents). Contrast medium patterns in the RSO had a sigmoid or ovoid shape confined to the affected facet joint, or a butterfly-shaped pattern extending into the contralateral facet joint, but rarely extending beyond the upper or lower level. LIMITATION: The rarity of unintentional injection into the RSO prevented a randomized controlled study design. CONCLUSIONS: Careful fluoroscopic examination of contrast medium patterns during lumbar TFESI is crucial to identify needle placement in the RSO. If detected, the procedure can be corrected by slightly advancing the needle into the foramen.

Preoperative laboratory measurements as a predictor for nasal steroid irrigations after sinus surgery for chronic rhinosinusitis with nasal polyps.

PURPOSE: To assess whether preoperative C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), immunoglobulin E (IgE), and blood eosinophil percentage (EOS) can predict need for steroid irrigations after FESS. MATERIALS AND METHODS: Adult patients at BIDMC from inception until September 8, 2023 with chronic rhinosinusitis with nasal polyps who underwent FESS and had preoperative CRP (n = 129), ESR (n = 79), IgE (n = 107), or EOS (n = 125) were included. Labs were divided into normal (CRP: 0-5.0 mg/L; ESR: 0-15 mm/h; IgE: 150-300Ul/mL; EOS: 1-7 %) and high groups (CRP: >5.0 mg/L; ESR: >15 mm/h; IgE: >300Ul/mL; EOS: >7 %). The primary outcome was need for intranasal steroid irrigations after FESS (≤4 weeks, 4-12 weeks, 12-26 weeks, 26-52 weeks, 1-3 years, 3-5 years, and > 5 years). Receiver operating characteristic curves were created to determine thresholds for predicting postoperative steroid irrigations. RESULTS: Elevated IgE required intranasal steroid irrigation at 1-3 years (normal 34 %, high 62 %, p = 0.02), 3-5 years (normal 24 %, high 48 %, p = 0.04), and > 5 years (normal 19 %, high 43 %, p = 0.02). Elevated EOS required intranasal steroid irrigation at 26-52 weeks (normal 7 %, high 25 %, p = 0.009) and > 5 years (normal 19 %, high 46 %, p = 0.005). The area under the curve for IgE at 1-3 years was 0.696 (95 % CI: 0.597-0.795) with cutoff at 144-148 Ul/mL. CRP and ESR were not predictive of postoperative intranasal steroid treatment. CONCLUSIONS: Elevated IgE and EOS (but not CRP or ESR) may predict need for intranasal steroid treatment after FESS.
