RESUMO
BACKGROUND: Japanese guidelines recommend triple inhaled corticosteroid (ICS)/long-acting muscarinic antagonist (LAMA)/long-acting ß2-agonist (LABA) therapy in patients with chronic obstructive pulmonary disease (COPD) and no concurrent asthma diagnosis who experience frequent exacerbations and have blood eosinophil (EOS) count ≥ 300 cells/mm3, and in patients with COPD and asthma with continuing/worsening symptoms despite receiving dual ICS/LABA therapy. These post-hoc analyses of the KRONOS study in patients with COPD and without an asthma diagnosis, examine the effects of fixed-dose triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) versus dual therapies on lung function and exacerbations based on blood EOS count - focusing on blood EOS count 100 to < 300 cells/mm3 - as a function of exacerbation history and COPD severity. METHODS: In KRONOS, patients were randomized to receive treatments that included BGF 320/14.4/10 µg, glycopyrronium/formoterol fumarate dihydrate (GFF) 14.4/10 µg, or budesonide/formoterol fumarate dihydrate (BFF) 320/10 µg via metered dose inhaler (two inhalations twice-daily for 24 weeks). These post-hoc analyses assessed changes from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over 12-24 weeks and moderate or severe COPD exacerbations rates over 24 weeks. The KRONOS study was not prospectively powered for these subgroup analyses. RESULTS: Among patients with blood EOS count 100 to < 300 cells/mm3, least squares mean treatment differences for lung function improvement favored BGF over BFF in patients without an exacerbation history in the past year and in patients with moderate and severe COPD, with observed differences ranging from 62 ml to 73 ml across populations. In this same blood EOS population, moderate or severe exacerbation rates were reduced for BGF relative to GFF by 56% in patients without an exacerbation history in the past year, by 47% in patients with moderate COPD, and by 50% in patients with severe COPD. CONCLUSIONS: These post-hoc analyses of patients with moderate-to-very severe COPD from the KRONOS study seem to indicate clinicians may want to consider a step-up to triple therapy in patients with persistent/worsening symptoms with blood EOS count > 100 cells/mm3, even if disease severity is moderate and there is no recent history of exacerbations.

Nefecon, a targeted-release capsule formulation of budesonide approved for the reduction of proteinuria in adults with primary immunoglobulin A nephropathy, targets overproduction of galactose-deficient immunoglobulin A type 1 in the Peyer's patches at the gut mucosal level. To investigate whether the commercial formulation of Nefecon capsules reliably releases budesonide to the distal ileum, a human study was conducted with test capsules reproducing the delayed-release function of Nefecon capsules. Caffeine was included in the test capsules as a marker for capsule opening in the gut since it appears rapidly in saliva after release from orally administered dosage forms. Magnetic resonance imaging with black iron oxide was used to determine the capsule's position in the gut at the time caffeine was first measured in saliva and additionally to directly visualize dispersion of the capsule contents in the gut. In vitro dissolution results confirmed that the test capsules had the same delayed-release characteristics as Nefecon capsules. In 10 of 12 human volunteers, the capsule was demonstrated to open in the distal ileum; in the other two subjects, it opened just past the ileocecal junction. These results compared favorably with the high degree of variability seen in other published imaging studies of delayed-release formulations targeting the gut. The test capsules were shown to reliably deliver their contents to the distal ileum, the region with the highest concentration of Peyer's patches.

By applying the phosphonic acid ligand to the solvothermal reaction of nitrobenzylphosphonic acid (H2L) with Cd(NO3)2·4H2O in a mixed solvent of water and DMF, a novel Cd(II)-based coordination polymer, {[Cd(L)(H2O)2](H2O)}n (1), was successfully synthesized in this study. The excellent fluorescence performance of complex 1 was confirmed through fluorescence spectroscopy testing, and the obtained CIE standard coordinates (0.1599, 0.0786) positioned it in the blue fluorescence region. Transparent hyaluronic acid/carboxymethyl chitosan hydrogels were prepared using chemical synthesis, and their internal microstructure was observed. Using budesonide as a drug model, a new budesonide metal gel was prepared, and its therapeutic efficacy in treating pediatric asthma was evaluated. Molecular docking simulations indicated that the Cd complex formed three hydrogen bonding interactions with the target protein through its nitro group, revealing the potential origin of its biological activity.
RESUMO
BACKGROUND AND AIM: Early treatment response of ulcerative colitis (UC) symptom resolution is desirable. This post hoc analysis evaluated efficacy outcomes, including endoscopic remission, by responder status and the influence of once-daily (QD) versus twice-daily (BID) budesonide foam dosing in patients with UC. METHODS: Data were pooled from phase 2 and phase 3 clinical trials of budesonide rectal foam QD or BID or placebo for up to 12 weeks. Outcomes were evaluated by treatment and budesonide administration regimen and by responder group: early (rectal bleeding subscore [RBS] 0 from Week 2 through Week 6), delayed (RBS 0 at Week 6), and nonresponder (RBS > 0 at Week 6). RESULTS: The main analysis set included 55 (QD) and 120 (BID) budesonide-treated patients and 116 placebo-treated patients. At Week 6, the trend in early response rate was significant among treatment groups (BID, 45.3%; QD, 32.1%; placebo, 12.8%; P < 0.0001). Among BID recipients, trends for complete endoscopic remission rate (Mayo endoscopic score [MES] = 0) and endoscopic remission rate (MES = 0 or 1) were significant among responder status groups (early responder, 67.4% and 95.4%, respectively; delayed responder, 48.1% and 85.2%; nonresponder, 24.0% and 64.0%; P < 0.001 for both). Regardless of the administration regimen, most early responders achieved endoscopic remission at Week 6. Among responder status groups, early responders' cumulative non-relapse period was greatest (P = 0.07). CONCLUSION: A BID budesonide administration regimen is preferred to increase the probability of early response and, following endoscopic remission, a better prognosis after stopping treatment.
RESUMO
OBJECTIVES: Oral viscous budesonide (OVB) is a common medication used to treat eosinophilic esophagitis (EoE). It is typically mixed with Splenda to produce a slurry, but other delivery vehicles have been used in clinical practice. We aimed to evaluate outcomes of pediatric EoE patients treated with OVB using different drug delivery vehicles. METHODS: We performed a retrospective chart review of pediatric EoE patients treated with OVB. The primary aim was to evaluate rates of histologic remission (defined by <15 eosinophils per high power field in both mid and distal esophagus) after 6-12 weeks of OVB treatment for each delivery vehicle. Secondary aims were to evaluate histologic response and endoscopic response and remission of different delivery vehicles, and to compare the efficacy of different treatment regimens. RESULTS: A total of 111 patients were included in the study. Median treatment duration was 3.4 months. Overall rate of histologic remission with OVB was 52.6%. There was no difference in rates of histologic remission (p = 0.313) or response (p = 0.195 and p = 0.681 in mid and distal esophagus, respectively) among the different vehicle types or treatment regimens. Similarly, there was no difference in endoscopic remission and response among the different vehicle types (p = 0.853 and p = 0.727) or treatment regimens (p = 0.244 and p = 0.157). Patients who achieve histologic remission were more likely to be non-Hispanic Caucasian. CONCLUSION: Our findings suggest there is no difference in histologic and endoscopic outcomes with various delivery vehicles or combination therapy with OVB in the treatment of EoE. More palatable and cost-effective vehicles can be used to treat EoE.

OBJECTIVE: The aim of this pilot study was to assess the efficacy of doxofylline as an ICS-sparing agent in the treatment of Mexican children with asthma. METHODS: 10-week, open-label, crossover, pilot study, we examined the steroid-sparing effect of doxofylline in Mexican children with asthma. Patients aged 6-16 years treated with inhaled corticosteroids (ICS) for at least 8 wk before enrollment were divided randomly into two groups at the baseline visit. Group A (n = 31) received doxofylline (18 mg/kg/day) plus standard-dose budesonide (D + SDB) for the first 4-week period followed by doxofylline plus reduced-dose budesonide (D + RDB) for the second 4-week period. Group B (n = 30) received D + RDB followed by D + SDB. Clinical outcomes assessed included lung function (forced expiratory volume; in 1 s, FEV1), fractional exhaled nitric oxide (FeNO), asthma control, number of exacerbations and use of rescue medication (salbutamol). RESULTS: It was shown that combined use of doxofylline and ICS may allow children with asthma to reduce their daily dose of ICS while maintaining lung function and improving asthma control (p = 0.008). There were few asthma exacerbations and only one patient required treatment with systemic corticosteroids. Rescue medication use decreased significantly in patients receiving D + SDB during the first 4-week period. CONCLUSIONS: Our results suggest that doxofylline may be a steroid-sparing treatment in asthma, but longer-term, controlled studies are needed to confirm these observations.

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.
RESUMO
OBJECTIVE: To review the efficacy, symptoms, inflammatory factors and pulmonary function of different doses of budesonide aerosol inhalation in the treatment of patients with asthma. METHODS: The Chinese and English literature databases were searched with "Effects of different doses of budesonide aerosol inhalation on the efficacy, lung function, inflammation, symptoms and adverse reactions in patients with asthma" as the search direction, and a Meta-analysis was performed. RESULTS: Compared with the low dose group, the efficacy, PEF and FEV1 were significantly increased and the clinical symptom score, TNF-α and IL-4 were significantly decreased in the high dose group (p < 0.05). There was no significant difference in IFN-γ level and the incidence of adverse reactions between the two groups (p > 0.05). CONCLUSION: High-dose budesonide aerosol inhalation therapy can improve the efficacy and lung function of patients, reduce inflammation and clinical symptoms, and does not increase the risk of adverse reactions, which is worthy of clinical promotion.
RESUMO
INTRODUCTION: Non-responsive coeliac disease (NRCD), where symptoms and enteropathy persist despite a prolonged gluten-free diet (GFD), is common. Refractory coeliac disease (RCD), characterised by malabsorption and extensive enteropathy, is rare but serious. In both, treatment options are limited. Topical budesonide may help and an open capsule format promoting proximal small intestinal delivery may be advantageous. AIM: To describe the effect of budesonide and its presentation on mucosal healing, symptoms, and tolerability in NRCD and RCD. METHODS: A retrospective cohort study of NRCD and RCD patients who received budesonide for enteropathy despite a strict GFD for over 12 months. Primary outcome was improvement in histology. Symptoms and adverse treatment effects were recorded. RESULTS: 50 patients with NRCD (n = 14; 86% F), RCD type 1 (n = 30; 60% F), and RCD type 2 (n = 6 based on aberrant duodenal T cells; 33% F) were identified. Common RCD symptoms were diarrhoea (68%), fatigue (40%), and weight loss (34%). 16 received closed capsule budesonide (CCB) 9 mg OD and 35 open capsule budesonide (OCB) 3 mg 3 times a day. Complete and partial mucosal healing was significantly higher after OCB compared to CCB (p < 0.001, Mann-Whitney U test). Symptom improvement was also significantly higher after OCB compared to CCB (p = 0.002, Mann-Whitney U test). Side effects were mild and self-limiting and were reported in 25% of both cohorts. CONCLUSION: OCB was well tolerated and associated with improvements in enteropathy (83%) and symptoms (90%) in NRCD and RCD. Our findings support OCB as the preferred 1st-line therapy for NRCD and RCD type 1.

Budesonide is a 'non-absorbable' corticosteroid often used for gut graft versus host disease. Systemic exposure is usually minimal because of metabolism by cytochrome (CYP) 3A4 in enterocytes and the liver. However, concomitant use of posaconazole and voriconazole, inhibitors of CYP3A4 commonly used as antifungal prophylaxis in allograft patients receiving immunosuppression, can lead to substantial systemic steroid exposure. This paper describes a case of severe iatrogenic Cushing syndrome and tertiary adrenal insufficiency because of this interaction, highlighting the necessity for improved awareness of this phenomenon.

BACKGROUND: Post-operative sore throat (POST) has an incidence ranging from 21 to 80%. To prevent the development of POST, several pharmacological measures have been tried. Aim of this study was to compare the efficacy of preoperative zinc, magnesium and budesonide gargles in reducing the incidence and severity of POST in patients who underwent endotracheal intubation for elective surgeries. METHODS: We conducted a prospective, randomized, double-blind, controlled equivalence trial in 180 patients admitted for elective surgical procedures under general anaesthesia. Patients were randomised into three groups; group Z received 40 mg Zinc, group M received 250 mg Magnesium Sulphate and group B received 200 µg Budesonide in the form of 30 ml tasteless and colourless gargle solutions. Sore throat assessment and haemodynamic recording was done postoperatively at immediate recovery (0 h) and 2, 4, 6, 8, 12 and 24 h post-operatively. POST was graded on a four-point scale (0-3). RESULTS: POST score was comparable at all recorded time points i.e. 0,2,4,6,8,12 and 24 h. Maximum incidence was seen at 8 h in group B (33.3%) and the minimum incidence was at 24 h in group Z (10%) (p > 0.05). It was found that the incidence of POST was more in the surgeries lasting longer than 2 h in all groups. This difference was found to be statistically significant in Groups M and B. The incidence of POST was found to be comparable between laparoscopic and open procedures. CONCLUSION: Magnesium, zinc and budesonide have an equivocal effect in the prevention of POST at different time points. The incidence of sore throat increases significantly in surgeries lasting more than two hours if magnesium or budesonide have been used as premedicant. Duration of surgery is an independent predictor for POST. TRIAL REGISTRATION: CTRI/2021/05/033741 Date-24/05/2021(Clinical Trial Registry of India).

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. TRIAL REGISTRATION: The study was registered at the Iranian Registry of Clinical Trials website under the code IRCT20201222049802N1. https://en.irct.ir/user/trial/48117/view .

BACKGROUND: Budesonide and tixocortol pivalate as markers of contact allergy to corticosteroids have been questioned, as they are not able to detect a significant percentage of allergic patients. OBJECTIVES: To investigate the potential role of clobetasol propionate in enhancing corticosteroid sensitisation detection. METHODS: Between January 2022 and December 2023, patients who attended centres involved in the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy were tested with an extended baseline series that included budesonide, tixocortol pivalate, clobetasol propionate 0.1% in ethanol and 1% in petrolatum. RESULTS: A total of 4338 patients were tested. Twenty-four patients were allergic to budesonide (0.55%, 95% CI: 0.37-0.82); nine patients were allergic to tixocortol pivalate (0.21%, 95% CI: 0.11-0.39); and 23 patients were allergic to clobetasol (0.53%, 95% CI: 0.35-0.79). Only four of those patients allergic to clobetasol were detected by budesonide and one by tixocortol pivalate. No significant differences in the number of positive tests were found between clobetasol in petrolatum or ethanol. CONCLUSIONS: In Spain budesonide remains the main corticosteroid allergy marker whereas the role of tixocortol pivalate is questionable. The addition of clobetasol propionate to the Spanish baseline series would improve the ability to detect patients allergic to corticosteroids.

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.

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.

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®.

The current budesonide formulations are inadequate for addressing left-sided colitis, and patients might hesitate to use an enema for a prolonged time. This study focuses on developing a single-layer coating for budesonide pellets targeting the descending colon. Pellets containing budesonide (1.5%w/w), PVP K30 (5%w/w), lactose monohydrate (25%w/w) and Avicel pH 102 (68.5%w/w) were prepared using extrusion spheronization technique. Coating formulations were designed using response surface methodology with pH and time-dependent Eudragits. Dissolution tests were conducted at different pH levels (1.2, 6.5, 6.8, and 7.2). Optimal coating formulation, considering coating level and the Eudragit (S + L) ratio to the total coating weight, was determined. Budesonide pellets were coated with the optimized composition and subjected to continuous dissolution testing simulating the gastrointestinal tract. The coating, with 48% S, 12% L, and 40% RS at a 10% coating level, demonstrated superior budesonide delivery to the descending colon. Coated pellets had a spherical shape with a uniform 30 µm thickness coating, exhibiting pH and time-dependent release. Notably, zero-order release kinetics was observed for the last 9 h in colonic conditions. The study suggests that an optimized single-layer coating, incorporating pH and time-dependent polymers, holds promise for consistently delivering budesonide to the descending colon.

Objective: To explore the clinical effect of various doses of Budesonide combined with Tiotropium bromide in the treatment of elderly patients with chronic obstructive pulmonary disease (COPD). Methods: Clinical data of elderly patients with COPD, admitted to Affiliated Hospital of Shaoxing University from April 2021 to February 2023, were retrospectively analyzed. Based on the dosage of Budesonide combined with Tiotropium bromide, patients were divided into Low-dose group (Budesonide = 1mg), Medium-dose group (Budesonide = 2mg), and High-dose group (Budesonide = 3mg). All groups were matched for age, gender, course of disease, and BMI. Patients treated with Tiotropium bromide alone were assigned to the Control group. The clinical effect, pulmonary function index level, symptom improvement, inflammatory factor index level and adverse reactions in all groups were analyzed and compared. Results: A total of 88 patients were included in this study with 22 patients in each group. The total efficacy of Medium-dose (90.91%) and High-dose group (90.91%) was significantly higher than that of Low-dose group (63.64%) and the Control group (59.09%) (P<0.05). After the treatment, levels of pulmonary function, symptom improvement and inflammatory factors in the High-dose and the Medium-dose groups were better than those in the Low-dose group and the Control group. Pulmonary function, symptom improvement and levels of inflammatory factors was significantly better in the Low-dose group compared to the Control group (P<0.05). Conclusions: Budesonide combined with tiotropium bromide is better than tiotropium bromide alone in the treatment of elderly patients with COPD. Compared with low (1mg) dosage, medium (2mg) and high (3mg) dosage of budesonide are more effective in improving lung function, alleviating symptoms, reducing inflammatory response,, and are not associated with increased rate of adverse reactions.
RESUMO
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.
RESUMO
Objective: To explore the clinical value of Vitamin-D combined with budesonide/formoterol (BF) and theophylline sodium glycinate (TSG) sustained-release tablets in the treatment of patients with chronic obstructive pulmonary disease (COPD). Methods: Medical records of 114 patients with CODP, treated in Wenzhou Geriatric Hospital from October 2020 to February 2023, were retrospectively analyzed. Of them, 59 received treatment with Vitamin-D combined with BF and TSG sustained-release tablets (Group-A), and 55 patients received treatment with BF combined with TSG sustained-release tablets (Group-B). Lung function indicators, blood gas status, inflammatory factors, fractional exhaled nitric oxide (FeNO), and 25-hydroxyvitamin D [25(OH)D] levels before and after the treatment in both groups were collected. Results: After the treatment, lung function indicators, blood gas status, inflammatory factors, FeNO, and 25 (OH) D levels in both groups were significantly improved compared to pretreatment levels, and were significantly better in the Group-A compared to Group-B (P<0.05). Conclusions: The combination of Vitamin-D, BF, and TSG sustained-release tablets can effectively regulate the blood gas status of patients with COPD, improve lung function, regulate FeNO and 25 (OH) D, and effectively downregulate the levels of inflammatory factors, thus reducing the degree of inflammatory response.
