Intraclass comparison of inhaled corticosteroids for the risk of pneumonia in chronic obstructive pulmonary airway disorder: a network meta-analysis and meta-regression.

BACKGROUND: Inhalational corticosteroids (ICS) were observed to increase the pneumonia risk in chronic obstructive pulmonary airway disorder (COPD). However, it is unknown whether any differences exist between the drugs within the ICS class. AIM: This study aimed to evaluate the risk of pneumonia associated with different ICS and identify factors that predict pneumonia in patients with moderate-to-severe COPD using a network meta-analysis. METHOD: Electronic databases (Medline, Cochrane CENTRAL and Google Scholar) were searched for trials comparing ICS in COPD patients. The outcomes were pneumonia and serious pneumonia. Odds ratios (OR) with 95% confidence interval (95% CI) were estimated. Meta-regression was used to identify the predictors. The strength of evidence was graded using the Grading of Recommendations, Assessment, Development, and Evaluations approach. RESULTS: Sixty-six studies (103,347 participants) were included. Fluticasone (OR: 1.46; 95% CI: 1.26, 1.7), mometasone (OR: 2.2; 95% CI: 1.05, 4.6), and beclometasone (OR: 1.7; 95% CI: 1.1, 2.6) were observed with an increased pneumonia risk compared to placebo. Fluticasone (OR: 1.5; 95% CI: 1.3, 1.7) was observed with an increased risk of serious pneumonia. High doses (OR: 1.2; 95% CI: 1.03, 1.4), BMI ≥ 25 kg/m2 (OR: 1.6; 95% CI: 1.1, 2.2), and history of exacerbations in the preceding year predicted the pneumonia risk. Evidence strength was moderate. CONCLUSION: ICS class differences in pneumonia risk were observed in terms of pooled effect estimates but it is unlikely that any clinically relevant differences exist. Risk-benefit analysis supports ICS use in moderate-severe COPD.

The impact of combined administration of surfactant and intratracheal budesonide compared to surfactant alone on bronchopulmonary dysplasia (BPD) and mortality rate in preterm infants with respiratory distress syndrome: a single-blind randomized clinical trial.

BACKGROUND: Respiratory distress syndrome (RDS) is one of the most important and common disorders among premature infants. OBJECTIVE: This study aimed to compare the effect of the combination of surfactant and budesonide with surfactant alone on Bronchopulmonary dysplasia (BPD) and mortality rate among premature infants with RDS. METHOD: An outcome assessor-blind randomized clinical trial was conducted on 134 premature infants with RDS who were born in Ayatollah Mousavi Hospital, Zanjan, Iran in 2021. The covariate adaptive randomization method was utilized to allocate participants into two groups (surfactant alone and a combination of surfactant and budesonide). The primary outcomes were BPD and Mortality rate from admission to hospital discharge. The data in this study were analyzed using SPSS software version 18. RESULTS: Overall the comparison of mortality rate and BPD between the two groups did not show a significant difference(p > 0.05). The subgroup results showed that administering surfactant with budesonide to infants under 30 weeks of age significantly reduced the number of deaths compared to using surfactant alone (5 vs. 17). Similar positive effects were observed for the occurrence of Pulmonary Hemorrhage, the need for a second dose of surfactant, oxygen index, mean blood pressure and mean arterial pressure (MAP) in infants under 34 weeks of age compared to more than 34 weeks (p < 0.05). CONCLUSION: These findings suggest that the combination therapy of surfactant and budesonide may be beneficial, particularly in preterm infants with less than 34 weeks gestational age and 1500 birth weight. However, further studies with larger sample sizes and longer follow-up periods are needed to confirm these results and assess long-term outcomes.

The Effects of Budesonide Inhalation Treatment on the Expression Levels of Serum IL-6, TGF-ß1, and IgE and Pulmonary Function in Patients with Cough Variant Asthma and an Evaluation of Treatment Efficacy.

Objective: To retrospectively study the effects of budesonide inhalation combined with conventional symptomatic treatment on serum inflammatory factor expression levels and pulmonary function in patients with cough variant asthma (CVA) and to evaluate treatment efficacy. Methods: This retrospective cohort study included 200 patients diagnosed with CVA at the Second Hospital of Jiaxing between January 2022 and June 2023 and given conventional symptomatic treatment plus budesonide inhalation were included in this study. Patients were divided into a no remission group, a partial remission group and a complete remission group based on treatment effect. The expression levels of serum inflammatory factors, cough symptom scores, and small airway function indicators in the three groups of patients at different time points were compared. Results: In the three groups of CVA patients, after receiving budesonide inhalation combined with conventional symptomatic treatment, the expression levels of serum IL-5, IL-6, IL-8, TNF-α, TGF-ß1, and IgE and number of eosinophils significantly decreased (P <0.05). There were statistically significant differences in the IL-6 and TGF-ß1 levels among the three groups of CVA patients at T1, T2 and T3. There were statistically significant differences in IgE levels, number of eosinophils, cough symptom scores, and small airway function indicators between T2 and T3 (P<0.05). The receiver operating characteristic (ROC) curve prediction analysis revealed significant differences in the expression of IL-6 and TGF-ß1 at T1, T2, and T3. Conclusion: Budesonide inhalation combined with conventional symptomatic treatment can significantly reduce the levels of serum inflammatory factors in patients with CVA to reduce inflammation and the allergic response, thereby reducing the cough symptom score, improving pulmonary function, and improving therapeutic efficacy. In addition, IL-6 and TGF-ß1 can be used as early predictors of budesonide inhalation efficacy.

Comparative Efficacy of Budesonide/Formoterol Versus Fluticasone/Salmeterol in Patients With Moderate-to-Severe Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis.

BACKGROUND/OBJECTIVE: To compare the efficacy of budesonide/formoterol (BF) versus fluticasone/salmeterol (FS) in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). METHODS: The PubMed, Embase, Cochrane Library, and Web of Science databases were searched for studies comparing BF versus FS in the treatment of COPD from inception to July 17, 2023. Outcomes, including exacerbations, hospitalizations, pneumonia, emergency department (ED) visits for COPD, length of hospitalization, and number of exacerbations, were compared using risk ratio (RR) with corresponding 95% confidence interval (CI) or weighted mean difference (WMD) with 95% CI. All statistical analyses were performed using Stata version 12.0. RESULTS: Ten studies comprising a total of 136,369 participants were included. Compared with those treated with FS, patients with COPD treated with BF experienced a reduced number of exacerbations (RR 0.91 [95% CI 0.83-1.00]; p = 0.040), hospitalizations (RR 0.77 [95% CI 0.67-0.88]; p < 0.001), and frequency of pneumonia (RR 0.77 [95% CI 0.64-0.92]; p = 0.05). However, no significant difference was observed between BF and FS in terms of ED visits for COPD (RR 0.87 [95% CI 0.69-1.10]; p = 0.243), length of hospitalization (WMD -0.18 [95% CI -0.62-0.27]; p = 0.437), and number of exacerbations (WMD -0.06 [95% CI -0.28-0.16]; p = 0.602). Notably, no significant heterogeneity was noted in length of hospitalization between the two groups, whereas clear heterogeneity was observed in other outcomes (I2 > 50%, p < 0.05). CONCLUSION: Compared with FS, BF therapy appears to be a more promising treatment strategy for patients with moderate-to-severe COPD; however, this should be verified in further high-quality studies.

Evolving Utilization of Topical Budesonide Following Endoscopic Sinus Surgery.

Topical budesonide irrigations are frequently prescribed after endoscopic sinus surgery (ESS) to manage mucosal inflammation. However, this off-label indication may conflict with health insurance formularies. We sought to quantify the relative frequency of postoperative budesonide prescriptions to determine if this could be considered common practice after ESS. We extracted and analyzed postoperative prescription data for patients undergoing ESS from 2016 to 2022 within our health care system. Overall, among 8157 ESS patients, 15.9% and 22.1% received topical budesonide prescriptions within 30 or 180 days postoperatively, respectively. On a year-over-year basis, budesonide prescription frequency increased significantly over time, culminating at 20.3% and 24.9% in 2022. Conversely, postoperative oral corticosteroid (OCS) prescriptions showed a decreasing frequency over the same time period (P < .001). Our results show topical budesonide irrigations are increasingly frequently prescribed after ESS and may offset postoperative OCS requirements. This argues for coverage of topical budesonide as a formulary medication after ESS.

Oral Budesonide and low serum albumin levels at surgery are associated with a higher risk of postoperative intra-abdominal septic complications after primary ileocaecal resection for Crohn's disease: A retrospective analysis of 853 consecutive patients.

BACKGROUND AND AIMS: The terminal ileum is the most frequent site of Crohn's Disease (CD) that necessitates surgery. Of the postoperative complications (POCs) associated with ileocaecal resection for CD, intra-abdominal septic complications (IASCs) include anastomotic leak, abscesses, and entero-cutaneous fistula. We aimed to identify predictors of IASCs and severe POCs (Clavien-Dindo ≥3) after primary ileocaecal resection for CD. METHODS: This is a retrospective single-centre cohort study including all consecutive primary ileocaecal resection for CD in a tertiary IBD centre between 2004 and 2021. RESULTS: A total of 853 patients underwent primary ileocaecal resection for CD. 307 (36.6 %) patients were receiving antibiotics, 253 (29.8 %), systemic steroids, and 178 (21.0 %) oral budesonide at surgery. At 90 days, 260 (30.8 %) patients developed POCs, 62 (7.3 %) severe POCs, and 56 (6.6 %) IASCs. At multivariate analysis, severe POCs were associated with lower preoperative albumin levels (OR1.58, 95 %CI 1.02-2.50, p = 0.040) and a history of cardiovascular diseases (OR2.36, 95 %CI 1.08-7.84, p = 0.030). IASCs were associated with lower preoperative albumin levels (OR1.81, 95 %CI 1.15-2.94, p = 0.011) and oral budesonide (OR2.07, 95 %CI 1.12-3.83, p = 0.021) with a dose-dependent effect. CONCLUSIONS: The independent association, dose-dependent effect, and biological plausibility of budesonide and IASCs suggest a robust causal effect. Oral budesonide should be carefully assessed before primary ileocaecal resection for CD.

Diagnosing and Treating IgAN: Steroids, Budesonide, or Maybe Both?

IgA nephropathy (IgAN), the most common primary glomerulonephritis worldwide, is characterized by a mesangial IgA deposit and a variety of histological lesions, as described by the Oxford classification system. Despite the well-described "four-hit hypothesis", there are still plenty of less or undescribed mechanisms that participate in the disease pathogenesis, such as B-cell priming, which seems to be initiated by different antigens in the intestinal microbiota. Diagnosis of the disease is currently based on kidney biopsy findings, as the sensitivity and specificity of the many serum and urinary biomarkers described so far do not seem to have diagnostic accuracy. Therapeutic strategies consist of the initial step of non-immune medication, aiming to reduce both the intraglomerular pressure and proteinuria to below 0.5 g/day, followed by systemic corticosteroid administration in patients who remain at high risk for progressive chronic kidney disease despite the maximum non-immune treatment. The 6-month systemic corticosteroid treatment reduces proteinuria levels; however, the increased possibility of adverse events and increased relapse rate after treatment raises the need for a new therapeutic approach. Targeted-release budesonide is a therapeutic modality that aims to inhibit disease pathogenetic pathways at early stages; it has minor systemic absorption and proven beneficial effects on renal function and proteinuria. In the present systemic review, the benefits and adverse events of steroids and budesonide are described, and the possibility of combined treatment is questioned in selected cases with active histologic lesions.

Thermodynamic and Structural Study of Budesonide-Exogenous Lung Surfactant System.

The clinical benefits of using exogenous pulmonary surfactant (EPS) as a carrier of budesonide (BUD), a non-halogenated corticosteroid with a broad anti-inflammatory effect, have been established. Using various experimental techniques (differential scanning calorimetry DSC, small- and wide- angle X-ray scattering SAXS/WAXS, small- angle neutron scattering SANS, fluorescence spectroscopy, dynamic light scattering DLS, and zeta potential), we investigated the effect of BUD on the thermodynamics and structure of the clinically used EPS, Curosurf®. We show that BUD facilitates the Curosurf® phase transition from the gel to the fluid state, resulting in a decrease in the temperature of the main phase transition (Tm) and enthalpy (ΔH). The morphology of the Curosurf® dispersion is maintained for BUD < 10 wt% of the Curosurf® mass; BUD slightly increases the repeat distance d of the fluid lamellar phase in multilamellar vesicles (MLVs) resulting from the thickening of the lipid bilayer. The bilayer thickening (~0.23 nm) was derived from SANS data. The presence of ~2 mmol/L of Ca2+ maintains the effect and structure of the MLVs. The changes in the lateral pressure of the Curosurf® bilayer revealed that the intercalated BUD between the acyl chains of the surfactant's lipid molecules resides deeper in the hydrophobic region when its content exceeds ~6 wt%. Our studies support the concept of a combined therapy utilising budesonide-enriched Curosurf®.

Evaluating the efficacy of nasal irrigation in postoperative functional endoscopic sinus surgery patients: a systematic review and meta-analysis.

PURPOSE: Functional endoscopic sinus surgery (FESS) is a mainstay surgical intervention for chronic rhinosinusitis with nasal polyposis (CRSwNP). Nasal irrigation, particularly with normal saline, is a widely recommended postoperative care modality. This systematic review and meta-analysis aimed to assess the efficacy of various nasal irrigation solutions in postoperative FESS patients. METHODS: A comprehensive search was conducted in multiple databases for randomized controlled trials investigating normal saline and various substances for nasal irrigation post-FESS. The systematic review followed PRISMA guidelines, and the meta-analysis used R software for data synthesis. Outcome measures included SNOT-22 and LKES scores. The Cochrane tool was employed to evaluate the potential for bias. RESULTS: Results from 14 studies, focusing on six each for SNOT-22 and LKES, revealed a significant reduction in symptoms and endoscopic scores with various solutions compared to normal saline. The meta-analysis using the random-effects model indicated a negative standardized mean difference (SMD) of - 0.69(95% CI [- 1.64; 0.27], p = 0.157) for symptoms and endoscopic scores (SMD = - 0.48, 95% CI [- 1.32; 0.36], z = - 1.12, p = 0.264). Subgroup analyses highlighted budesonide's efficacy over normal saline, but substantial heterogeneity and potential publication bias were noted. CONCLUSION: Nasal irrigation with various solutions postoperative FESS patients demonstrated significant improvements in patient-reported symptoms and endoscopic scores compared to normal saline. Budesonide appeared particularly effective. However, high heterogeneity and potential publication bias warrant cautious interpretation. Standardized outcome measures and further research are needed to strengthen the evidence.

Quantification of Budesonide Retained in the Sinonasal Cavity After High-Volume Saline Irrigation in Post-Operative Chronic Rhinosinusitis.

BACKGROUND: Budesonide high-volume saline irrigations (HVSIs) are routinely used to treat chronic rhinosinusitis (CRS) due to improved sinonasal delivery and efficacy compared to intranasal corticosteroid sprays. The off-label use of budesonide is assumed to be safe, with several studies suggesting the systemically absorbed dose of budesonide HVSI is low. However, the actual budesonide dose retained in the sinonasal cavity following HVSI is unknown. The objective of this study was to quantify the retained dose of budesonide after HVSI. METHODS: Adult patients diagnosed with CRS who had undergone endoscopic sinus surgery (ESS) and were prescribed budesonide HVSI were enrolled into a prospective, observational cohort study. Patients performed budesonide HVSI (0.5 mg dose) under supervision in an outpatient clinic, and irrigation effluent was collected. High-performance liquid chromatography was employed to determine the dose of budesonide retained after HVSI. RESULTS: Twenty-four patients met inclusion criteria. The average corrected retained dose of budesonide across the cohort was 0.171 ± 0.087 mg (37.9% of administered budesonide). Increased time from ESS significantly impacted the measured retained dose, with those 3 months post-ESS retaining 27.4% of administered budesonide (P = .0004). CONCLUSION: The retained dose of budesonide in patients with CRS after HVSI was found to be significantly higher than previously estimated and decreased with time post-ESS. Given that budesonide HVSI is a cornerstone of care in CRS, defining the retained dose and the potential systemic implications is critical to understanding the safety of budesonide HVSI.

Efficacy of the posterior nasal nerve resection combined with hormone transnasal nebulization on difficult-to-treat rhinosinusitis: a retrospective analysis.

OBJECTIVE: A retrospective analysis was performed to explore the clinical effect of the Posterior Nasal Nerve (PNN) resection combined with hormone transnasal nebulization on Difficult-to-Treat Rhinosinusitis (DTRS). METHODS: A total of 120 DTRS patients were selected and divided into a control group (n = 60) and a study group (n = 60) according to different treatments. The control group patients were treated via PNN resection, followed by normal saline transnasal nebulization; the study group patients were given PNN resection and then treated with budesonide suspension transnasal nebulization. Subsequently, the comparison was performed between the two groups in terms of (1) Clinical baseline characteristics; (2) Sino-nasal Outcome Test (SNOT)-22 scores before treatment and after 3-months, 6-months and 12-months of treatment; (3) Lund-MacKay scores before treatment and after 10, 30, 90, and 180 days of treatment; (4) Incidence of adverse reactions during treatment. RESULTS: There was no significant difference in SNOT-22 or Lund-Kennedy scores between the two groups before treatment (p > 0.05). After treatment, the SNOT-22 and Lund-Kennedy scores of the control and the study groups were decreased, and compared with the control group, the SNOT-22 and Lund-Kennedy scores in the study group improved more significantly (p < 0.05). In addition, the study group and the control group presented with 1 and 4 cases of nasal adhesion, 2 and 3 cases of epistaxis, 1 and 4 cases of sinus orifice obstruction, 1 and 3 cases of lacrimal duct injuries, respectively. The incidence of adverse reactions in the study group was significantly lower than that in the control group (8.3% vs. 23.3%) (p < 0.05). CONCLUSION: PNN resection combined with hormone transnasal nebulization treatment can improve the symptoms and quality of life of DTRS patients, with good clinical efficacy but few adverse reactions. Therefore, such combination treatment deserves a promotion and application clinically. LEVEL OF EVIDENCE: Level 3.

The effect of budesonide combined with bifidobacteria and lactobacilli on lung function and gut microbiota of patients with chronic obstructive pulmonary disease.

Objective: To explore the effects of budesonide combined with Bifidobacteria and Lactobacilli on the lung function and intestinal microbiota of patients with chronic obstructive pulmonary disease (COPD). Methods: Clinical data of 124 COPD patients admitted to Fengcheng Hospital, Fengxian District, Shanghai from February 2021 to February 2023 were retrospectively analyzed. Patients either received budesonide treatment alone (n=59, control group) or budesonide combined with Bifidobacteria and Lactobacilli (n=65, observation group). Levels of lung function indicators, symptom relief time, gut microbiota levels, and quality of life were compared between the two groups before and after the treatment. Results: After two weeks of treatment, the improvement of lung function in the observation group was better than that in the control group (P<0.05). Compared to budesonide treatment alone, combined budesonide, Bifidobacteria, and Lactobacilli treatment were associated with shorter symptom relief time (P<0.05), and with more significant improvement of intestinal microbiota level (P<0.05) and the quality of life (P<0.05). Conclusions: Budesonide combined with Bifidobacteria and Lactobacilli can effectively alleviate clinical symptoms, regulate intestinal microbiota, improve lung function and the quality of life of COPD patients.

Expert panel consensus recommendations on the utilization of nebulized budesonide for managing asthma and COPD in both stable and exacerbation stages in Thailand.

OBJECTIVE: This study investigated the utilization of nebulized budesonide for acute asthma and COPD exacerbations as well as for maintenance therapy in adults. DATA SOURCES: We conducted a search on PubMed for nebulized budesonide treatment. SELECTED STUDIES: Selecting all English-language papers that utilize Mesh phrases "asthma," "COPD," "budesonide," "nebulized," "adult," "exacerbation," and "maintenance" without temporal restrictions, and narrowing down to clinical research such as RCTs, observational studies, and real-world studies. RESULTS: Analysis of 25 studies was conducted to assess the effectiveness of nebulized budesonide in asthma (n = 10) and COPD (n = 15). The panel in Thailand recommended incorporating nebulized budesonide as an additional or alternative treatment option to the standard of care and systemic corticosteroids (SCS) based on the findings. CONCLUSION: Nebulized budesonide is effective and well-tolerated in treating asthma and COPD, with less systemic adverse effects compared to systemic corticosteroids. High-dose nebulized budesonide can enhance clinical outcomes for severe and mild exacerbations with slow systemic corticosteroid response. Nebulized budesonide can substitute systemic corticosteroids in some situations.

Poly(malic acid)-budesonide nanoconjugates embedded in microparticles for lung administration.

To improve the therapeutic activity of inhaled glucocorticoids and reduce potential side effects, we designed a formulation combining the advantages of nanoparticles, which have an enhanced uptake by alveolar cells, allow targeted delivery and sustained drug release, as well as limited drug systemic passage, with those of microparticles, which display good alveolar deposition. Herein, a polymer-drug conjugate, poly(malic acid)-budesonide (PMAB), was first synthesized with either 11, 20, 33, or 43 mol% budesonide (drug:polymer from 1:8 to 3:4), the drug creating hydrophobic domains. The obtained conjugates self-assemble into nanoconjugates in water, yielding excellent drug loading of up to 73 wt%, with 80-100 nm diameters. In vitro assays showed that budesonide could be steadily released from the nanoconjugates, and the anti-inflammatory activity was preserved, as evidenced by reduced cytokine production in LPS-activated RAW 264.7 macrophages. Nanoconjugates were then embedded into microparticles through spray-drying with L-leucine, forming nano-embedded microparticles (NEMs). NEMs were produced with an aerodynamic diameter close to 1 µm and a density below 0.1 g.cm-3, indicative of a high alveolar deposition. NEMs spray-dried with the less hydrophobic nanoconjugates, PMAB 1:4, were readily dissolved in simulated lung fluid and were chosen for in vivo experiments to study pharmacokinetics in healthy rats. As it was released in vivo from NEMs, sustained distribution of budesonide was obtained for 48 h in lung tissue, cells, and lining fluid. With high loading rates, modulable release kinetics, and low cytotoxicity, these nanoconjugates delivered by NEMs are promising for the more efficient treatment of pulmonary inflammatory diseases.

National survey conducted among Italian pediatricians examining the therapeutic management of croup.

OBJECTIVES: Practice-to-recommendations gaps exist in croup management and have not been critically investigated. This study examined the therapeutic management of croup among a national sample of Italian pediatric providers. METHODS: A survey was administered online to a sample of primary care and hospital-based pediatricians. Demographic data, perception regarding disease severity, treatment and knowledge of croup, choices of croup treatment medications, and knowledge of and adherence to treatment recommendations were compared between hospital and primary care pediatricians. Oral corticosteroids alone, oral corticosteroids with or without nebulized epinephrine and nebulized epinephrine plus oral or inhaled corticosteroids were considered the correct management in mild, moderate and severe croup, respectively. The determinants for correct management were examined using multivariate logistic regression analysis. RESULTS: Six hundred forty-nine pediatricians answered at least 50% of the survey questions and were included in the analysis. Providers reported extensive use of inhaled corticosteroids for mild and moderate croup. Recommended treatment for mild, moderate and severe croup was administered in 46/647 (7.1%), 181/645 (28.0%) and 263/643 (40.9%) participants, respectively. Provider's age and knowledge of Westley Croup Score were significant predictors for correct management of mild croup. Being a hospital pediatrician and perception of croup as a clinically relevant condition were significant for moderate croup. CONCLUSIONS: Significant differences exist between recommended guidelines and clinical practice in croup management. This study suggests wide variability in both the treatment of croup and clinical decision making strategies among hospital and primary care pediatricians. Addressing this issue could lead to noteworthy clinical and economic benefits.

The association between drugs and repeated treatment with budesonide in patients with microscopic colitis: a retrospective observational study.

Background: Smoking and the use of non-steroidal anti-inflammatory drugs (NSAIDs) acetylsalicylic acid (ASA), proton pump inhibitors (PPIs), serotonin reuptake inhibitors (SSRIs), and statins have been associated with microscopic colitis (MC). Objectives: We investigated whether these factors were associated with repeated budesonide treatments in patients diagnosed with MC. Design: Retrospective observational study. Methods: All patients with a histologically verified diagnosis of MC at our clinic between the years 2006 and 2022 were identified. Baseline factors and drugs prescribed before and after diagnosis were registered. The influence of risk factors on the odds of having a prescription of oral budesonide and the odds of having a second course of budesonide was studied. Results: Patients with MC (n = 183) with a mean age of 62.3 years [standard deviation (SD): 13.3 years] were followed for a median of 5 years (25th-75th percentile 4-10 years) after diagnosis. In all, 138 patients (75%) had at least one prescription of budesonide after diagnosis, and 90 patients (49%) had at least one clinical relapse treated with budesonide. Patients who had been prescribed NSAIDs within 1 year before clinical relapse had higher odds for clinical relapse [odds ratio (OR): 3.70, 95% confidence interval (CI): 1.06-12.9] but there was no increased risk for clinical relapse for the use of ASA (OR: 0.99, 95% CI: 0.39-2.90), PPIs (OR: 1.09, 95% CI: 0.45-2.63), SSRI (OR: 1.41, 95% CI: 0.82-2.44), or statins (OR: 0.83, 95% CI: 0.35-1.99). No association was seen between being a smoker and/or being prescribed NSAID, ASA, PPI, SSRI, and statins at baseline and the odds of having a prescription of oral budesonide within 1 year after diagnosis. Conclusion: The risk of being prescribed a second course of budesonide is associated with receiving a prescription of NSAIDs but not with the use of ASA, PPIs, SSRIs, and statins.

The use of drugs and the odds for patients with microscopic colitis of having a second course of budesonide Microscopic colitis is a common cause of chronic diarrhea. Previous studies have shown that the use of non-steroidal anti-inflammatory drugs, acetylsalicylic acid, proton-pump inhibitors, serotonin reuptake inhibitors and statins are used more often in patients who later develop microscopic colitis. We aimed to study if these drugs also had an association to an increased risk of disease flares treated with budesonide in 183 patients with known microscopic colitis. Oral budesonide for 6-8 weeks are recommended for disease flares of microscopic colitis. In our study, 90 patients (49%) were prescribed a second course of budesonide probably due to a disease flare. We found a higher odds for being prescribed a second course of budesonide in patients with microscopic colitis who were prescribed non-steroidal anti-inflammatory drugs but no higher risk for the other 'risk drugs' for microscopic colitis.

Double Blinded Randomized Controlled Trial Comparing Budesonide and Saline Nasal Rinses in the Post-operative Management of Chronic Rhinosinusitis.

Post-operative management of chronic rhinosinusitis is very crucial for outcomes following surgery, Normal saline nasal irrigation and steroid spray form the standard treatment of care in this period. However nasal irrigation may not be adequate and spray is usually started after 2 weeks of surgery which in any case does not deliver optimum dosage of drug to the paranasal sinus mucosa. Budesonide nasal irrigation in a high-volume low-pressure system could be the solution for a better outcome. A double blinded randomized control trial with 88 patients in 2 groups of 44 each received normal saline or Budesonide nasal irrigation (0.5 mg in 200 ml) twice daily. Patients were followed up at 2 weeks post-operatively and 3 months, a SNOT 22 and Lund Kennedy Endoscopic scores were assessed for subjective and objective assessment. Subset analysis of only CRS patients (55) were done, and results presented. Patient reported subjective score at 3 months post operatively, SNOT22 was significantly (p < 0.0001) improved with the use of Budesonide irrigation (26.69 ± 2.92) as compared to Normal saline (30.54 ± 2.81) and objective assessment score, LKES was significantly (p = 0.0031) better in Budesonide group (4.06 + 0.74) in comparison to Normal saline in the saline (4.50 + 0.67) respectively. The mean scores 3 months post op visit was significantly lower for both subjective SNOT (p < 0.001) and objective score LKES (p < 0.0001) in Budesonide groups. Budesonide nasal irrigation with positive pressure high volume device has better patient benefits and wound healing when compared to normal saline irrigation in the post-operative management of chronic rhinosinusitis.

Budesonide/Formoterol or Budesonide/Albuterol as Anti-Inflammatory Reliever Therapy for Asthma.

Overuse of reliever as short-acting beta-agonist and associated underuse of controller as inhaled corticosteroid (ICS) administered via separate inhalers results in worse asthma outcomes. Such discordance can be obviated by combining both controller and reliever in the same inhaler. So-called anti-inflammatory reliever (AIR) therapy comprises the use of a single inhaler containing an ICS such as budesonide (BUD) in conjunction with a reliever as either albuterol (ALB) or formoterol (FORM), to be used on demand, with variable dosing driven by asthma symptoms in a flexible patient-centered regimen. Global guidelines now support the use of BUD-ALB as AIR therapy to reduce exacerbations, either on its own in mild asthma or in conjunction with fixed-dose maintenance ICS-long-acting beta-agonist in moderate to severe asthma. Using BUD-FORM on its own allows patients to seamlessly move in an intuitive flexible fashion between AIR and maintenance and reliever therapy, by stepping up and down the dosing escalator across a spectrum of asthma severities. Head-to-head clinical studies are indicated to compare BUD-FORM versus BUD-ALB as AIR in mild asthma, and also BUD-FORM as maintenance and reliever therapy versus BUD-ALB as AIR plus maintenance ICS-long-acting beta-agonist in moderate to severe asthma. Patients should be encouraged to make an informed decision in conjunction with their health care professional regarding the best therapeutic option tailored to their individual needs, which in turn is likely to result in long-term compliance and associated optimal asthma control.

Effect of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler combined with nasal high-flow nasal cannula on elderly patients with COPD and respiratory failure.

Objective: To explore the clinical effect of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) combined with high-flow nasal cannula (HFNC) in the treatment of elderly patients with chronic obstructive pulmonary disease (COPD) and respiratory failure. Methods: The clinical records of 94 elderly patients with COPD and respiratory failure who were treated in Yongkang First People's Hospital from February 2022 to January 2023 were retrospectively selected. Among them, 46 patients received HFNC alone (Control-group) and 48 patients received HFNC combined with BGF MDI (Study-group). The treatment effect, arterial blood gas status, pulmonary function, and acute physiology and chronic health evaluation (APACHE) II score before and after treatment were analyzed in both groups. Results: The total efficacy of treatment in the Study-group (95.8%) was higher than that in the Control-group (78.3%) (P<0.05). After treatment, the partial pressure of arterial carbon dioxide (PaCO2), residual volume, and APACHE II scores in the two groups decreased compared to those before treatment, with the Study-group lower overall. However, arterial oxygen saturation (SaO2), oxygen partial pressure (PaO2), the percentage of peak expiratory flow (PEF), and forced expiratory volume in one second (FEV1) as percent of predicted (%FEV1) were higher than before treatment, and higher in the Study-group (P<0.05). Conclusions: Compared with HFNC alone, BGF MDI combined with HFNC can effectively regulate the arterial blood gas status of elderly patients with COPD and respiratory failure, restore pulmonary function, and improve the overall treatment effect.
