To describe severe infection, foci of infection, microorganisms, associated factors, and impact on mortality in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). The study was based on a multicenter prospective cohort of patients with RA-ILD followed up from 2015 to 2023. The main outcome measures were incident severe infection and fatal infection. We evaluated infectious foci, etiologic agents, vaccination status, variables associated with lung function, and clinical-therapeutic variables in RA. The incidence rate (IR) for infection and mortality was calculated per 100 person-years, and 3 multivariate models were constructed to explore factors associated with infection. We followed up 148 patients with RA-ILD for a median 56.7 months (699.3 person-years). During this period, 142 patients (96%) had at least 1 infection. A total of 368 infectious episodes were recorded, with an IR of 52.6 per 100 person-years. Of the 48 patients who died, 65% did so from infection. Respiratory infections were the most common first infection (74%), infection overall (74%), and fatal infection (80%) and were caused mostly by SARS CoV-2 , and influenza A virus. The factors associated with an increased risk of infection and death in patients with RA-ILD were age, inflammatory activity, and therapy with corticosteroids and immunosuppressants. Patients with RA-ILD have a high risk of serious infection, especially respiratory infection. Infection develops early, is recurrent, and is frequently fatal. The presence of associated factors such as advanced age, joint inflammation, and treatment highlight the importance of integrated and preventive medical care.

SARS-CoV-2 (COVID-19) patients who develop acute respiratory distress syndrome (ARDS) can suffer acute lung injury, or even death. Early identification of severe disease is essential in order to control COVID-19 and improve prognosis. Oxidative stress (OS) appears to play an important role in COVID-19 pathogenesis; we therefore conceived a study of the potential discriminative ability of serum biomarkers in patients with ARDS and those with mild to moderate disease (non-ARDS). 60 subjects were enrolled in a single-centre, prospective cohort study of consecutively admitted patients: 29 ARDS/31 non-ARDS. Blood samples were drawn and marker levels analysed by spectrophotometry and immunoassay techniques. C-reactive protein (CRP), lactate dehydrogenase (LDH), and ferritin were significantly higher in ARDS versus non-ARDS cases at hospital admission. Leukocytes, LDH, ferritin, interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α) were also significantly elevated in ARDS compared to non-ARDS patients during the hospital stay. Total thiol (TT) was found to be significantly lower in ARDS. Conversely, D-dimer, matrix metalloproteinase-9 (MMP-9) and advanced glycosylated end products (AGE) were elevated. Leukocytes, LDH, CRP, ferritin and IL-6 were found to be significantly higher in non-survivors. However, lymphocyte, tumour necrosis factor beta (TGF-β), and TT were lower. In summary, our results support the potential value of TT, ferritin and LDH as prognostic biomarkers for ARDS development in COVID-19 patients, distinguishing non-ARDS from ARDS (AUCs = 0.92; 0.91; 0.89) in a fast and cost-effective manner. These oxidative/inflammatory parameters appear to play an important role in COVID-19 monitoring and can be used in the clinical management of patients.

There is increasing evidence supporting the use of morphofunctional assessment (MFA) as a tool for clinical characterization and decision-making in malnourished patients. MFA enables the diagnosis of malnutrition, sarcopenia, obesity, and cachexia, leading to a novel phenotype-based classification of nutritional disorders. Bioelectrical impedance analysis (BIVA), nutritional ultrasound® (NU) and computed tomography (CT) are included, along with functional tests like the Timed Up and Go test (TUG). Myoesteatosis, detectable via CT, can occur independently from nutritional phenotypes and has been identified as a significant mortality predictor in idiophatic pulmonary fibrosis (IPF). Our aim is to analyze the prevalence and overlap of nutritional phenotypes in IPF and evaluate the prognostic value of myoesteatosis. Our bicenter cross-sectional study included 82 IPF patients (84.1% male and with a medium age of 71.1 ± 7.35 years). MFA was performed using BIVA, NU, CT at the T12 level (CT-T12), the handgrip strength (HGS) test, and the TUG. CT-T12 BC parameters were analyzed using FocusedON® software, while statistical analyses were conducted with JAMOVI version 2.3.22. All four major nutritional phenotypes were represented in our cohort, with significant overlap. A total of 80.5% met the GLIM criteria for malnutrition, 14.6% had cachexia, 17% were sarcopenic, and 28% were obese. Of the obese patients, 70% were also malnourished, while 100% of sarcopenic obese patients (5.9% of total) had malnutrition. A total of 55% of sarcopenic patients with available CT also had myosteatosis, suggesting muscle quality deterioration as a potential driver of functional impairment. The presence of myosteatosis > 15% in T12-CT was an independent predictor of 12-month mortality (HR = 3.13; 95% CI: 1.01–9.70; p = 0.049), with survival rates of 78.1% vs. 96.6% in patients with vs. without myosteatosis, respectively. To conclude, this study underscores the relevance of MFA in the nutritional characterization of patients with IPF, demonstrating its potential to identify specific phenotypes associated with malnutrition, functional impairment, and the presence of myoesteatosis, thereby providing a valuable tool for clinical decision-making.

Triple therapy significantly enhances both clinical and functional outcomes in patients with uncontrolled chronic obstructive pulmonary disease (COPD), even when they are already receiving treatment. However, it is often prescribed with multiple inhalers, which can affect adherence to treatment. The evidence on the effectiveness of extrafine single inhaler triple therapy (efSITT) compared to multiple inhalers triple therapy (MITT) in patients with moderate-to-severe COPD in the real-world setting is limited. TRIPOLI was a unicentric retrospective observational study that compared one year of efSITT with beclomethasone dipropionate, formoterol fumarate dihydrate, and glycopyrronium with one year of MITT in terms of exacerbations, use of rescue medication, adherence, and lung function in patients with COPD. A total of 71 patients were analyzed. The mean number of total and moderate exacerbations showed a significant reduction of 27.56% (p = 0.0043) and 29.56% (p = 0.0008), respectively, after efSITT. The percentage of patients with poor adherence decreased from 30.2% to 9.9% with efSITT and the proportion of patients with complete adherence increased from 55.8% to 81.7%. An improvement of 2.29% was described in mean forced expiratory volume in the first second (% pred). No differences were observed in the rate of pneumonia between the treatment with efSITT and MITT. The TRIPOLI study suggests that switching from MITT to efSITT might reduce exacerbations in patients with moderate-to-severe COPD, likely attributable to improved adherence in real-world settings.

Cytisinicline has proven to be an effective, efficient, and safe molecule in smoking cessation. However, the established 25-day regimen could be insufficient in a high percentage of smokers, so it is necessary to study maintained therapies of this drug. This study aims to compare the efficacy of the cytisinicline regimen used in routine clinical practice versus 2 maintained regimens of 50 and 75 days, respectively. In addition, the safety and economic impact of each regime will be determined. A prospective, multicenter, open-label, controlled, parallel, phase IV clinical trial of 402 smoker patients prepared to quit smoking. The study was conducted in 10 hospitals in Spain. A control group is compared to 2 intervention groups in which the duration of the drug is increased without increasing its dose, administering half and all, respectively, of an additional marketed container that includes 100 tablets. Thus, participants will be randomized to three groups in a 1:1:1 ratio to receive cytisinicline: (1) a control group treated with cytisinicline according to the usual clinical guidelines and product information (25 days); (2) a group with a 50-day cytisinicline regimen (an additional 25 days at a dose of 1.5 mg every 12 hours), seeking to increase its efficacy while minimally impacting adherence; and (3) a group with a 75-day regimen (an additional 50 days at a dose of 1.5 mg every 12 hours), attempting to increase its efficacy, although the longer duration of the drug may threaten adherence. Efficacy in the 3 arms will be analyzed through sustained abstinence at 6 and 12 months, point abstinence rate assessed every 7 days, and abstinence rate from Day 25 to Day 50 and from Day 25 to Day 75 in the 3 study arms. (1) The variation in withdrawal and craving symptoms in the 3 groups, (2) safety through the percentage of adverse events in the 3 treatment arms, and (3) economic impact by evaluating the cost-effectiveness and cost-utility ratios of the 2 prolonged regimens versus the usual clinical cytisinicline regimen. To calculate the differences between the 3 groups for each outcome variable, a univariate analysis will be performed. Statistically significant variables will be included in a multivariate model. Recruitment for the trial and patient enrollment were completed in November 2026. Follow-up of all participants will extend to December 2027. In conclusion, this study evaluates the optimization of cytisinicline in daily clinical practice, increasing the benefits of its pharmaceutical properties without affecting patient safety. All of this will improve the effectiveness of smoking cessation by reducing the number of smokers, which implies lower morbidity and mortality and lower costs associated with smoking.

Background: The value of the phase angle (PhA), measured via bioelectrical impedance analysis (BIA), could be considered a good marker of the cell mass and the cell damage of a patient; however, there are new techniques, such as muscle ultrasonography, that allow the quantity and quality of muscle to be assessed in a minimally invasive way. The aim of this study is to determine the prognostic value of morphofunctional techniques in the prognosis of mortality in patients with idiopathic pulmonary fibrosis (IPF). Methods: This multicenter, cross-sectional study included 86 patients with idiopathic pulmonary fibrosis with a mean age of 71 years, 82.7% of whom were male. The nutritional risk of the patients was assessed by means of questionnaires, such as the Subjective Global Assessment (SGA), and non-invasive functional techniques, including BIA, nutritional ultrasound, and hand grip strength (HGS). Statistical analysis of the sample was performed using JAMOVI version 2.3.22. Results: Correlations were made between the RF-CSA techniques with PhA (r = 0.48, p < 0.001), BCM (r = 0.70, p < 0.001), SMI (r = 0.64, p < 0.001), and HGS (r = 0.54, p < 0.001). The cut-off points for 12-month mortality were PhA = 4.5° (AUC = 0.722, sensitivity of 72.7% and specificity of 66.6%), BCM = 28.8 kg (AUC = 0.609, sensitivity of 32.4% and specificity of 100.0%), RF-CSA = 3.00 cm2 (AUC = 0.857, sensitivity of 64.4% and specificity of 100.0%), 6MMW = 420 m (AUC = 0.830, sensitivity of 63.27% and specificity of 100.0%), and TUG = 7.2 s (AUC = 0.771, sensitivity of 100.0% and specificity of 56.67%). In addition, a multivariate analysis was performed with RF-CSA, HR = 8.11 (1.39–47.16, p = 0.020), and PhA of 6.35 (1.29–31.15, p = 0.023), taking into account age, sex, and BMI to determine mortality. Finally, a Kaplan–Meier survival analysis was conducted with low or normal values for classical parameters (GAP and T6MM) and new parameters (PhA, BCM, RF-CSA, and TUG). Conclusion: RF-CSA and PhA were shown to be good prognostic markers of 12-month mortality and could, therefore, be useful screening tools to complement the nutritional assessment of IPF patients.

To describe the clinical management of asthmatic patients and the level of compliance with the (GEMA, Spanish Guidelines for Asthma Management) in the influential al area of Virgen de la Victoria University Hospital, Málaga (Spain). Descriptive, cross-sectional study in asthma patients from the Virgen de la Victoria University Hospital influential area, Málaga (Spain). Asthma Control Test (ACT) results, demographic and clinical characteristics, and GEMA indicators of quality asthma care were obtained from each participating patient. Two hundred and eighty-eight patients (64.2% woman, mean age 48.6 years) were included in the study. The evaluation of the level of compliance with the GEMA quality indicators showed that in 20.8% of the patients the diagnosis of asthma was confirmed by spirometry and bronchodilator test, and 52.5% of the patients with suspicion of allergic asthma performed a sensitization test. Among the smoker patients, 76.3% were recommended to stop smoking; 14.2% of the patients received a paper-based educational plan. Regarding asthma treatment, 92.3% of patients with persistent asthma received inhaled glucocorticoids (IGC). IGC and LABA were the most common treatments for asthma, used in combination (ICG + LABA) in 139 (48.3%) patients; 32.6% discontinued SABA treatment during the study period. Asthma was well controlled in 54.9% of the patients (ACT score ≥20), and 13.9% of the patients registered exacerbations during the previous year with a mean (SD) of 1.38 (0.74) events. Most of the GEMA quality indicators of asthma care are not followed in real-world clinical practice. Specialists select the best option among the available treatments but there is an unmet need for training plans in other relevant aspects, such as diagnosis and/or disease monitoring.

Objective: To prospectively evaluate the safety and efficacy profile of abatacept in patients with rheumatoid arthritis–associated interstitial lung disease (RA-ILD). Methods: We performed a prospective observational multicenter study of a cohort of patients with RA-ILD treated with abatacept between 2015 and 2021. Patients were evaluated using high-resolution computed tomography and pulmonary function tests at initiation, 12 months, and the end of follow-up. The effectiveness of abatacept was evaluated based on whether ILD improved, stabilized, progressed, or was fatal. We also evaluated factors such as infection, hospitalization, and inflammatory activity using the 28-joint Disease Activity Score with the erythrocyte sedimentation rate (DAS28-ESR). Cox regression analysis was performed to identify factors associated with progression of lung disease. Results: The study population comprised 57 patients with RA-ILD treated with abatacept for a median (IQR) of 27.3 (12.2–42.8) months. Lung disease had progressed before starting abatacept in 45.6% of patients. At the end of follow-up, lung disease had improved or stabilized in 41 patients (71.9%) and worsened in 13 (22.8%); 3 patients (5.3%) died. No significant decreases were observed in forced vital capacity (FVC) or in the diffusing capacity of the lung for carbon monoxide (DLCO).The factors associated with progression of RA-ILD were baseline DAS28-ESR (OR [95% CI], 2.52 [1.03–3.12]; p = 0.041), FVC (OR [95% CI], 0.82 [0.70–0.96]; p = 0.019), and DLCO (OR [95% CI], 0.83 [0.72–0.96]; p = 0.018). Only 10.5% of patients experienced severe adverse effects. Conclusion: Pulmonary function and joint inflammation stabilized in 71% of patients with RA-ILD treated with abatacept. Abatacept had a favorable safety profile.

Objectives: To describe the frequency of COVID-19 and the effect of vaccination in patients with interstitial lung disease and systemic autoimmune disease (ILD-SAD) and to identify factors associated with infection and severity of COVID-19. Methods: We performed a cross-sectional multicenter study of patients with ILD-SAD followed between June and October 2021. The main variable was COVID-19 infection confirmed by a positive polymerase chain reaction (PCR) result for SARS-CoV-2. The secondary variables included severity of COVID-19, if the patient had to be admitted to hospital or died of the disease, and vaccination status. Other variables included clinical and treatment characteristics, pulmonary function and high-resolution computed tomography. Two logistic regression was performed to explore factors associated with “COVID-19” and “severe COVID-19”. Results: We included 176 patients with ILD-SAD: 105 (59.7%) had rheumatoid arthritis, 49 (27.8%) systemic sclerosis, and 22 (12.54%) inflammatory myopathies. We recorded 22/179 (12.5%) SARS-CoV-2 infections, 7/22 (31.8%) of them were severe and 3/22 (13.22%) died. As to the vaccination, 163/176 (92.6%) patients received the complete doses. The factors associated with SARS-CoV-2 infection were FVC (OR (95% CI), 0.971 (0.946–0.989); p = 0.040), vaccination (OR (95% CI), 0.169 (0.030–0.570); p = 0.004), and rituximab (OR (95% CI), 3.490 (1.129–6.100); p = 0.029). The factors associated with severe COVID-19 were the protective effect of the vaccine (OR (95% CI), 0.024 (0.004–0.170); p < 0.001) and diabetes mellitus (OR (95% CI), 4.923 (1.508–19.097); p = 0.018). Conclusions: Around 13% of patients with ILD-SAD had SARS-CoV-2 infection, which was severe in approximately one-third. Most patients with severe infection were not fully vaccinated.

Objectives: To describe the characteristics and progression of interstitial lung disease in patients with associated systemic autoimmune disease (ILD-SAI) and to identify factors associated with progression and mortality. Patients and methods: We performed a multicenter, retrospective, observational study of patients with ILD-SAI followed between 2015 and 2020. We collected clinical data and performed pulmonary function testing and high-resolution computed tomography at diagnosis and at the final visit. The main outcome measure at the end of follow-up was forced vital capacity (FVC) >10% or diffusing capacity of the lungs for carbon monoxide >15% and radiological progression or death. Cox regression analysis was performed to identify factors associated with worsening of ILD. Results: We included 204 patients with ILD-SAI: 123 (60.3%) had rheumatoid arthritis (RA), 58 had (28.4%) systemic sclerosis, and 23 (11.3%) had inflammatory myopathy. After a median (IQR) period of 56 (29.8–93.3) months, lung disease had stabilized in 98 patients (48%), improved in 33 (16.1%), and worsened in 44 (21.5%). A total of 29 patients (14.2%) died. Progression and hospitalization were more frequent in patients with RA (p = 0.010). The multivariate analysis showed the independent predictors for worsening of ILD-SAI to be RA (HR, 1.9 [95% CI, 1.3–2.7]), usual interstitial pneumonia pattern (HR, 1.7 [95% CI, 1.0–2.9]), FVC (%) (HR, 2.3 [95% CI, 1.4–3.9]), and smoking (HR, 2.7 [95%CI, 1.6–4.7]). Conclusion: Disease stabilizes or improves after a median of 5 years in more than half of patients with ILD-SAI, although more than one-third die. Data on subgroups and risk factors could help us to predict poorer outcomes.
