Background: Real-world data on currently used biologic agents in patients with severe asthma are lacking. Methods: In this retrospective study, we recorded between 16 May 2020 and 31 December 2024 consecutive patients who presented to our asthma outpatient clinic received a diagnosis of uncontrolled severe asthma and were treated with biologic agents. Outcomes included a comparison of disease phenotypic characteristics, as well as asthma control, lung function, longitudinal use of corticosteroids, and hospitalizations due to exacerbations at baseline and post-biologic treatment at 6-month follow-up. Results: We identified 80 patients with uncontrolled severe asthma treated with biologic agents. The median age (95% CI) at the time of diagnosis was 67.0 (61.0 to 70.0) years. Most patients were female (65.0%, n = 52) and never smokers (51.3%, n = 41). The median value of ACT (95% CI) was 15 (15 to 16) at the time of diagnosis. The mean FEV₁% predicted ±SD at the baseline was 68.9 ± 22.0. The median value of blood eosinophils (95% CI) was 365 (252 to 448) K/μL in the overall population. One-third (36.3%) of patients were hospitalized due to severe asthma exacerbation in the previous year. Longitudinal use of oral corticosteroids was recorded in 11.3% of included patients. Three patients (3.8%) were treated with omalizumab, 23 patients (28.8%) with mepolizumab, 33 patients (41.2%) with benralizumab and 21 patients (26.2%) with tezepelumab. The median value of ACT (95% CI) post-biologic treatment at 6-month follow-up was 20 (20 to 21), p < 0.0001. The mean FEV₁% predicted ±SD at 6-month follow-up was 77.6 ± 25.2, p = 0.12. The median value of blood eosinophils (95% CI) 6 months after initiation of biologic treatment was 100 (40 to 121) K/μL, p < 0.0001. Elimination of hospitalizations due to asthma flares was recorded in 97.5% of patients (p < 0.0001). With regard to the longitudinal use of oral corticosteroids, we noticed that 96.2% of patients achieved discontinuation. No treatment-related adverse events were noticed. Conclusions: The administration of current biologic agents in patients with severe asthma seems to be both effective and safe, sparing the toxicity of oral corticosteroids.

Background: Accurate and timely molecular testing in patients with non-small cell lung cancer (NSCLC) is mandatory for targeted therapies and improved outcomes. Real-world obstacles, including geographic distance from specialized lung cancer services, along with comorbidities, may delay molecular diagnosis and subsequent treatment, therefore hampering survival. Methods: We conducted a retrospective, multi-departmental observational study of 927 patients with newly diagnosed NSCLC that were referred to a tertiary hospital in western Greece between January 2021 and December 2024. Patients were classified based on distance of residence (<30 km vs. ≥30 km). Clinical characteristics, time elapsed from pathological to final molecular diagnosis, and survival outcomes were analyzed and compared. Multivariable Cox regression was used to identify independent predictors of overall survival. Results: Patients residing ≥30 km away (61.2%) experienced delays in molecular testing (median 31 vs. 26 days, p = 0.002) and were less likely to undergo such testing (p = 0.012) compared to those residing 30 km also had a higher prevalence of COPD (42.5% vs. 31.2%, p = 0.002). Median survival from initial pathological diagnosis to death was significantly shorter in non-urban patients (129 vs. 215 days, p = 0.010). A molecular testing delay >35 days was independently associated with worse survival (HR = 0.684, 95% CI: 0.508–0.923, p = 0.013). No differences in TNM stage distribution were observed between geographical groups. Conclusions: Geographic disparities significantly impact access to advanced lung cancer services and molecular diagnostics and may provisionally affect prognosis in NSCLC. Improving testing pathways, incorporating reflex testing in pathological molecular analysis, and optimizing referral systems in rural areas may help to reduce inequalities and improve patient outcomes.

Background and Objectives: Despite the devastating impact of acute exacerbations of fibrotic interstitial lung diseases (AE-fILDs), established treatment strategies are majorly lacking. The therapeutic potential of intravenous immunoglobulin (IVIG) in AE-fILDs was explored considering its anti-inflammatory and immunomodulatory effects, as well as the immunocompromised status of fILD patients and the high frequency of infections that AE-fILDs triggers. Materials and Methods: This was an observational, retrospective study. We investigated the therapeutic potential of IVIG in patients hospitalized for AE-fILDs between May 2021 and November 2024. Results: We included 39 patients diagnosed with AE-fILDs. All patients received IVIG (total dose of 1 g/kg, divided into three daily doses), pulse corticosteroids for three days and broad-spectrum antibiotics. No adverse events were considered to be related to IVIG therapy during the study period. The in-hospital and the 90-day mortality were 10 (26%) and 13 (33%) patients, respectively. Twenty-nine patients (74%) were discharged and 18 of them (62%) were in need of long-term oxygen therapy. The mean PaO₂/FiO₂ ratio (P/F ratio) was 183 mmHg on admission and 294 mmHg on discharge (t-test, p < 0.0001). Conclusions: This study suggests a potential therapeutic signal, indicating that IVIG is a relatively harmless, well-tolerated, and a potentially effective add-on treatment to current therapeutic approaches. Further research is essential to clarify the role of IVIG, determine optimal treatment protocols, and assess its efficacy in different ILD subtypes.

Background: Hypersensitivity pneumonitis (HP) represents a chronic lung disease with an unpredictable clinical course. There is a pressing need for clinically applicable prognostic biomarkers in patients with HP. Methods: This was an observational, retrospective study. We investigated the prognostic potential of complete blood count parameters in treatment-naïve patients diagnosed with HP between 15 December 2010 and 1 October 2023. Receiver operating characteristic (ROC) curve analysis identified the optimal cut-off thresholds for each parameter in terms of mortality prediction. Results: We included 129 patients diagnosed with HP [median age: 68.0 years (95% CI: 65.0 to 69.0), fibrotic HP: n = 85, 65.9%]. Patients with HP and an eosinophil count > 160 cells/μL [ROC curve, area under curve (AUC): 0.61] exhibited increased mortality risk compared to patients with HP and an eosinophil count ≤ 160 cells/μL [Kaplan–Meier, HR: 2.95 (95% CI: 1.36 to 6.42), p = 0.006]. Patients with HP and a monocyte count > 350 cells/μL (ROC curve, AUC: 0.52) had worse survival compared to patients with HP and a monocyte count lower than this threshold [Kaplan–Meier, HR: 2.48 (95% CI: 1.03 to 5.09), p = 0.04]. Patients with HP and an eosinophil–lymphocyte ratio (ELR) > 0.09 (ROC curve, AUC: 0.64) had a higher risk of mortality compared to patients with HP and ELR ≤ 0.09 [Kaplan–Meier, HR: 2.75 (95% CI: 1.3 to 5.78), p = 0.008]. Conclusions: This study demonstrated that eosinophil count, monocyte count, and ELR could be prognostic biomarkers in patients with HP. Further studies aiming to validate the prognostic potential of complete blood count parameters in patients with HP are greatly anticipated.
