Trends and Outcomes in Pituitary Apoplexy Management: A Spanish Observational Multicenter Study.

Currently, the management for pituitary apoplexy (PA) has been promoted toward a more conservative approach, particularly for patients with low-grade PA scores. Our aim was to investigate trends in PA management and compare clinical presentation, therapeutic approaches, and outcomes before and after 2017, additionally to evaluate long-term outcomes in conservatively treated patients. Spanish multicenter, retrospective study. Statistical analyses compared clinical presentation and outcomes between periods, adjusting for confounders. A total of 215 patients with PA and nonfunctioning pituitary adenoma were included, with the median age of 62.2 years and 68.4% were male patients. Of which 94 (43.7%) were diagnosed before 2017 and 121 (56.3%) in 2017 or later. Conservative treatment increased from 17% before to 30.6% in the recent period (odd ratio 0.47, 95% CI 0.24-0.90, P 0.02) This trend remained significant after adjusting for hospital, age, and Knosp grade (odd ratio 0.46, 95% CI 0.22-0.89, P = .03). However, surgery remained the most frequently used therapeutic option in both periods. There were no statistically significant differences in outcomes at 3 months between periods. Surgery compared with conservative management was associated with higher permanent arginine vasopressin deficiency in both periods (0 vs 17.9%, P = .07 before 2017; 0 vs 16.7%, P = .01 after). Up to 89.7% of patients treated conservatively, presented more than 25% spontaneous tumor shrinkage, and 74.4% had more than 50% tumor reduction. Although conservative management increased in the last years, surgery remains the predominant option. Patients managed conservatively experience a lower risk of permanent arginine vasopressin deficiency, and a high proportion exhibit clinically significant tumor shrinkage over time.

Prognostic risk and survival of asymptomatic IgM monoclonal gammopathy: Results from a Spanish Multicenter Registry.

Asymptomatic IgM gammopathy encompasses IgM monoclonal gammopathy of undetermined significance (MGUS) and asymptomatic Waldenström macroglobulinemia (AWM), both having a risk of progression to symptomatic disease. Here, we assessed the risk of progression and the mortality of 956 patients with asymptomatic IgM gammopathy across 25 Spanish centers. After a median follow-up of 5.7 years, 156 patients progressed, most of them to symptomatic WM (SWM). The cumulative incidence of progression was 13% and 20% at 5 and 10 years, respectively. The serum IgM ≥10 g/L, bone marrow (BM) infiltration ≥20%, β2-microglobulin ≥3 mg/L, and albumin <4 g/dL were the most potent predictors of disease progression in a multivariate Cox regression model, allowing the identification of three risk categories. The probability of progression to symptomatic disease at 5 years was 4.5%, 15.7%, and 42.8% for low-, intermediate-, and high-risk groups, respectively. In patients without a BM evaluation, the presence of none or 1 risk factor and 2 or 3 risk factors conferred a progression risk of 6% and 27% at 5 years, respectively. The model was independent of the presence of MYD88 L265P, which conferred a negative impact only in AWM patients. The relative survival (RS) ratio at 5 years of asymptomatic patients was similar to the Spanish population, which contrasted with the 0.76 5-year RS of SWM patients. Overall, the Spanish Multicenter Model comprehensively describes the risk of progression of asymptomatic patients and shows that the excess mortality is increased only in the symptomatic stage of the disease.

A booster dose of SARS-COV-2 vaccine improves suboptimal seroconversion rates in patients with inflammatory bowel disease. Results of a prospective multicenter study of GETECCU (VACOVEII study)

BackgroundThe response to SARS-CoV-2 vaccination decreases in inflammatory bowel disease (IBD) patients, specially under anti-TNF treatment. However, data on medium-term effectiveness are limited, specially using new recommended seroconversion rate (>260BAU/mL). Our aim was to evaluate the 6-month>260 BAU-seroconversion rate after full vaccination and after booster-dose. MethodsVACOVEII is a Spanish multicenter, prospective study promoted by GETECCU. IBD patients full vaccinated against SARS-CoV-2 and without previous COVID-19 infection, treated or not with immunosuppressants, were included. The booster dose was administered 6 months after the full vaccination. Seroconversion was set at 260BAU/mL, according to most recent recommendations and was assessed 6 months after the full vaccination and 6 months after booster-dose. ResultsBetween October 2021 and March 2022, 313 patients were included (124 no treatment or mesalazine; 55 immunomodulators; 87 anti-TNF; 19 anti-integrin; and 28 ustekinumab). Most patients received mRNA-vaccines (86%). Six months after full vaccination, overall seroconversion rate was 44.1%, being significantly lower among patients on anti-TNF (19.5%, p<0.001) and ustekinumab (35.7%, p=0.031). The seroconversion rate after booster was 92%. Again, anti-TNF patients had a significantly lower seroconversion rate (67%, p<0.001). mRNA-vaccine improved seroconversion rate (OR 11.720 [95% CI 2.26–60.512]). ConclusionThe full vaccination regimen achieves suboptimal response in IBD patients, specially among those anti-TNF or ustekinumab. The booster dose improves seroconversion rate in all patients, although it remains limited in those treated with anti-TNF. These results reinforce the need to prioritize future booster doses in patients on immunosuppressants therapy, specially under anti-TNF, and using mRNA-vaccines.

Pituitary Apoplexy: Comorbidities, Management and Outcomes. A Spanish Observational Multicenter Study

Abstract Background Pituitary apoplexy (PA) is the paradigm of endocrine and neurosurgical emergency. Objective To evaluate the comorbidities, risk factors, clinical presentation, pituitary apoplexy score (PAS) and the outcomes of surgical vs. conservative management of PA in Spain. Methods Spanish multicenter, observational study of 301 patients with acute PA. Statistical analyses compared risk factors, clinical presentation and outcomes between the surgical and conservative treatment groups, adjusting for potential confounders. The prevalence of cardiovascular risk factors in patients with pituitary apoplexy was compared with the Spanish population and with patients with non-functioning pituitary adenomas. Results Median age was 59.3 years, 201 (66.8%) were men and non-functioning adenomas (77.9%) were the most common tumor type. The prevalence of diabetes (20.3% vs 13.9%, p&amp;lt;0.01), hypertension (48.8% vs 33.4%, p&amp;lt;0.01) and dyslipidemia (44.2% vs 23.3%, p&amp;lt;0.01), exceeded the Spanish age-adjusted population prevalence. Overall, 209 (69.4%) underwent surgery and 92 (30.6%) received conservative treatment. Surgical patients had larger tumors (26.2 vs 21.0 mm, p&amp;lt;0.01), chiasmal compression more frequently (77.2% vs 53.4%, p&amp;lt;0.01) and higher values of PAS. In the follow-up, while there were no statistically significant differences in anterior pituitary hormonal deficits between treatments, permanent vasopressin deficiency was more frequent after surgery (14.8% vs 3.3%, p&amp;lt;0.01). Conclusion There is a high burden of cardiovascular risk factors among patients with PA suggesting that metabolic factors may play a potential role in the development of PA. This underscores the need for comprehensive management of these conditions in addition to treating the apoplexy itself in this population. Surgical management has a relevant place in PA approach mainly in patients with higher PAS. However, it leads permanent vasopressin deficit more frequently than conservative approach.

Evaluating the Safety of the Intragastric Balloon: Spanish Multicenter Experience in 20,680 Cases and with 12 Different Balloon Models.

Intragastric balloon (IGB) is a minimally invasive and reversible option for obesity treatment. There is a worldwide growing number of different IGB models. The efficacy and safety profile for each model must be demonstrated. We aim to evaluate IGB safety profile according to the experience of the Spanish Bariatric Endoscopy Group (GETTEMO). A survey of 37 IGBs safety-related questions was sent to all GETTEMO members, to retrospectively collect a multicenter Spanish registry. Incidence, causes, and resolution of both major and minor complications and adverse events (AEs), including legal consequences, differentiated for each balloon model were evaluated. Secondary outcome was weight loss data to confirm efficacy. Twenty-one Spanish hospitals experienced in IGBs responded. The overall data encompassed 20,680 IGBs, including 12 different models. Mean %TBWL of 17.66 ± 2.5% was observed. Early removal rate due to intolerance was 3.62%. Mean major complications rate was 0.70% (> 1% in Spatz2, HB, and Spatz3 models), mainly complicated gastric ulcer. Minor AEs rate was 6.37%, mainly esophagitis. Nine cases (0.04%) required surgery. A single case of mortality (0.0048%) occurred. Seven lawsuits (0.0034%) were received, all with favorable resolution. In the Spanish experience accumulating 20,680 IGBs and including 12 different balloon models, a low incidence rate of major complications and minor AEs are observed (0.70% and 6.37%, respectively), mostly resolved with medical/endoscopic management. IGB shows good tolerance and efficacy profile. These safety data are within the accepted quality standards.

Childhood-Onset Non-Infectious Uveitis in the “Biologic Era”. Results From Spanish Multicenter Multidisciplinary Real-World Clinical Settings

ABSTRACT Objective To characterize and describe clinical experience with childhood-onset non-infectious uveitis. Study Design A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared. Results IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use. Conclusion Prognosis of childhood uveitis has improved in the “biologic era,” particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.

Assessing Outcomes of Patients Subject to Intensive Care to Facilitate Organ Donation: A Spanish Multicenter Prospective Study.

Intensive Care to facilitate Organ Donation (ICOD) consists of the initiation or continuation of intensive care measures in patients with a devastating brain injury (DBI) in whom curative treatment is deemed futile and death by neurological criteria (DNC) is foreseen, to incorporate organ donation into their end-of-life plans. In this study we evaluate the outcomes of patients subject to ICOD and identify radiological and clinical factors associated with progression to DNC. In this first prospective multicenter study we tested by multivariate regression the association of clinical and radiological severity features with progression to DNC. Of the 194 patients, 144 (74.2%) patients fulfilled DNC after a median of 25h (95% IQR: 17-44) from ICOD onset. Two patients (1%) shifted from ICOD to curative treatment, both were alive at discharge. Factors associated with progression to DNC included: age below 70 years, clinical score consistent with severe brain injury, instability, intracranial hemorrhage, midline shift ≥5mm and certain types of brain herniation. Overall 151 (77.8%) patients progressed to organ donation. Based on these results, we conclude that ICOD is a beneficial and efficient practice that can contribute to the pool of deceased donors.

Frailty Changes After Liver Transplantation. Results From a Spanish Multicenter Prospective Cohort Study.

Until now, there has been limited evidence, primarily from US cohorts, focusing on frailty as a patient-oriented outcome after liver transplantation (LT). Our study aimed to explore the relationship between pre- and post-LT frailty in a multicenter European cohort of outpatients with cirrhosis undergoing LT. We conducted a prospective analysis of data from 180 LT recipients recruited between 2018 and 2020 from 5 Spanish centers. Participants underwent objective and subjective frailty assessments using the Liver Frailty Index (LFI) and the Subjective Clinician Assessment (SCA) pretransplant and at 3- and/or 6-mo posttransplant. The median pretransplant LFI was 3.9, showing minimal change at 3 mo (3.8; P = 0.331) and improvement at 6-mo post-LT (3.6; P = 0.001). Conversely, the SCA significantly improved early post-LT: at 3 mo, poor SCA decreased from 11% to 1%, and good SCA increased from 54% to 89% (P < 0.001), remaining stable between 3- and 6-mo post-LT. Multivariable analysis revealed that each 0.1 increase in pretransplant LFI correlated with a reduced probability of being robust at 3-mo (odds ratio [OR] = 0.75; P < 0.001) and 6-mo post-LT (OR = 0.74; P < 0.001). There was poor concordance between SCA and LFI, with SCA underestimating frailty both pre- and post-LT (Kappa < 0.20). In our European cohort, incomplete improvement of physical frailty was observed, with <20% achieving robust physical condition within 6-mo post-LT. The pretransplant LFI strongly predicted posttransplant frailty. As the SCA tends to overestimate physical function, we recommend using both subjective and objective tools for frailty assessment in LT candidates and recipients.

Ceft-to-Ceft Study: Real-Life Experience with Ceftaroline and Ceftobiprole in Treatment of the Principal Infectious Syndromes in a Spanish Multicenter Hospital Cohort.

To compare the real-life effectiveness and safety of ceftaroline fosamil (ceftaroline-F) and ceftobiprole medocaril (ceftobiprole-M) for infections in hospitalized patients. This comparative, observational, retrospective, and multicenter Spanish study included patients receiving outpatient parenteral antimicrobial therapy (OPAT) and hospitalized patients treated for at least 48 h with ceftaroline-F or ceftobiprole-M between their first incorporation in the clinical protocol of each hospital and 31 July 2022. Ceftaroline-F was administered to 227 patients and ceftobiprole-M to 212. In comparison to the latter, ceftaroline-F-treated participants were younger (63.02 vs. 66.40 years, OR 1.1; 95%CI: 1.001-1.05) and had higher rates of septic shock (OR 0.27; 95%CI: 0.09-0.81) and higher frequencies of targeted (57.7 vs. 29.7%; OR: 0.35; 95%CI: 0.18-0.69) and combined (89.0 vs. 45.8%, OR: 0.13; 95%CI: 0.06-0.28) therapies that were second line or more (82.4% vs. 64.6%%; OR 0.35; 95%CI: 0.18-0.69), and higher rates of infections due to Gram-positive cocci (92.7 vs. 64.7%, p = 0.001), bacteremia (51.9 vs. 21.7%, p = 0.001), infective endocarditis (24.2 vs. 2.4%, p = 0.0001), and mechanical ventilation-associated pneumonia (8.8 vs. 2.4%, p = 0.0001). Ceftobiprole-M was more frequently administered against polymicrobial infections (38.1 vs. 14.0%, p = 0.001), those produced by Gram-negative bacilli (19.7 vs. 6.0%, p = 0.0001), nosocomial pneumonia (33 vs. 10.6%, p = 0.0001), and skin and soft-tissue infections (25.4 vs. 10.1%, p = 0.0001). Patients treated with ceftaroline-F had a longer hospital stay (36 (IQR: 19-60) vs. 19.50 (IQR: 12-30.75, p = 0.0001) days), with no difference in infection-related mortality at 14 (13.2 vs. 8.0%, p = 0.078) or 28 (4.8 vs. 3.3%, p = 0.415) days or in dropout rate for adverse effects (2.2 vs. 0.9%; p = 1). The fifth-generation cephalosporins, ceftaroline-F and ceftobiprole-M, are safe and effective in real life, with no difference between them in health outcomes.

A booster dose of SARS-COV-2 vaccine improves suboptimal seroconversion rates in patients with inflammatory bowel disease. Results of a prospective multicenter study of GETECCU (VACOVEII study)

BackgroundThe response to SARS-CoV-2 vaccination decreases in inflammatory bowel disease (IBD) patients, specially under anti-TNF treatment. However, data on medium-term effectiveness are limited, specially using new recommended seroconversion rate (>260BAU/mL). Our aim was to evaluate the 6-month>260 BAU-seroconversion rate after full vaccination and after booster-dose. MethodsVACOVEII is a Spanish multicenter, prospective study promoted by GETECCU. IBD patients full vaccinated against SARS-CoV-2 and without previous COVID-19 infection, treated or not with immunosuppressants, were included. The booster dose was administered 6 months after the full vaccination. Seroconversion was set at 260BAU/mL, according to most recent recommendations and was assessed 6 months after the full vaccination and 6 months after booster-dose. ResultsBetween October 2021 and March 2022, 313 patients were included (124 no treatment or mesalazine; 55 immunomodulators; 87 anti-TNF; 19 anti-integrin; and 28 ustekinumab). Most patients received mRNA-vaccines (86%). Six months after full vaccination, overall seroconversion rate was 44.1%, being significantly lower among patients on anti-TNF (19.5%, p<0.001) and ustekinumab (35.7%, p=0.031). The seroconversion rate after booster was 92%. Again, anti-TNF patients had a significantly lower seroconversion rate (67%, p<0.001). mRNA-vaccine improved seroconversion rate (OR 11.720 [95% CI 2.26–60.512]). ConclusionThe full vaccination regimen achieves suboptimal response in IBD patients, specially among those anti-TNF or ustekinumab. The booster dose improves seroconversion rate in all patients, although it remains limited in those treated with anti-TNF. These results reinforce the need to prioritize future booster doses in patients on immunosuppressants therapy, specially under anti-TNF, and using mRNA-vaccines.

Takotsubo Syndrome, Stressful Triggers, and Risk of Recurrence

The risk of recurrence in takotsubo syndrome (TTS) appears to be low, although previous studies have shown conflicting results and factors associated with recurrences are unclear. The aim of this study is to evaluate the incidence and predictors of TTS recurrences. Adult patients included in the Spanish Multicenter REgistry of TAKOtsubo syndrome (RETAKO) between January 2003 and September 2019 were identified. Patients were categorized based on recurrences during follow-up and a multivariate logistic regression model was used to identify factors associated with recurrences. A total of 1097 patients (mean age 71.0±11.9 years, 87% females) were included, repeated TTS events were documented in 44 patients (4.0%), including 13 patients with prior TTS and 31 patients with recurrent TTS during a median follow-up of 279 days. Two patients (0.02%) had two episodes of recurrence. Compared to patients who had no recurrence of TTS, those with recurrent TTS more frequently had no identifiable stressful trigger in the index admission (20 [64.5%] vs 352 [33.0%], p <0.001). Primary TTS, defined as TTS without physical trigger, was also more common in the recurrence group (93.5% vs 68.3%, p <0.001). The only factor independently associated with recurrences was the absence of an identifiable trigger (odds ratio 3.7 [95% confidence interval 1.8-7.8], p=0.001). In conclusion, our data indicate that for patients presenting with TTS, the rate of early recurrent TTS is approximately 4% per year. Among TTS patients, those who have no identifiable trigger events appear to have a higher rate of recurrence.

Treatment of early borderline lesions in low immunological risk kidney transplant patients: a Spanish multicenter, randomized, controlled parallel-group study protocol: the TRAINING study

BackgroundSubclinical inflammation, including borderline lesions (BL), is very common (30–40%) after kidney transplantation (KT), even in low immunological risk patients, and can lead to interstitial fibrosis/tubular atrophy (IFTA) and worsening of renal function with graft loss. Few controlled studies have analyzed the therapeutic benefit of treating these BL on renal function and graft histology. Furthermore, these studies have only used bolus steroids, which may be insufficient to slow the progression of these lesions. Klotho, a transmembrane protein produced mainly in the kidney with antifibrotic properties, plays a crucial role in the senescence-inflammation binomial of kidney tissue. Systemic and local inflammation decrease renal tissue expression and soluble levels of α-klotho. It is therefore important to determine whether treatment of BL prevents a decrease in α-klotho levels, progression of IFTA, and loss of kidney function.MethodsThe TRAINING study will randomize 80 patients with low immunological risk who will receive their first KT. The aim of the study is to determine whether the treatment of early BL (3rd month post-KT) with polyclonal rabbit antithymocyte globulin (Grafalon®) (6 mg/kg/day) prevents or decreases the progression of IFTA and the worsening of graft function compared to conventional therapy after two years post-KT, as well as to analyze whether treatment of BL with Grafalon® can modify the expression and levels of klotho, as well as the pro-inflammatory cytokines that regulate its expression.DiscussionThis phase IV investigator-driven, randomized, placebo-controlled clinical trial will examine the efficacy and safety of Grafalon® treatment in low-immunological-risk KT patients with early BL.Trial registrationclinicaltrials.gov: NCT04936282.

EP08.02-149 Spanish Multicenter Retrospective Study of Real-Life Experience of Advanced NSCLC with EGFR Exon 20 Insertions Treated With Amivantamab

Amivantamab is a novel anti-EGFR/c-MET bispecific antibody with clinical activity in EGFR mutated(m) advanced non-small cell lung cancer (aNSCLC) harboring exon20 insertions (ex20ins), recently approved by FDA; the activity/safety in real-world data (RWD) is very limited. We aimed to assess the activity/safety of amivantamab in a RWD-cohort of patients with Ex20ins aNSCLC from an Expanded Access Program (EAP).

Translated article] Surgical Risk Following Anatomic Lung Resection in Thoracic Surgery: A Prediction Model Derived From a Spanish Multicenter Database

IntroductionThe aim of this study was to develop a surgical risk prediction model in patients undergoing anatomic lung resections from the registry of the Spanish Video-Assisted Thoracic Surgery Group (GEVATS). MethodsData were collected from 3533 patients undergoing anatomic lung resection for any diagnosis between December 20, 2016 and March 20, 2018.We defined a combined outcome variable: death or Clavien-Dindo grade IV complication at 90 days after surgery. Univariate and multivariate analyses were performed by logistic regression. Internal validation of the model was performed using resampling techniques. ResultsThe incidence of the outcome variable was 4.29% (95% CI 3.6–4.9). The variables remaining in the final logistic model were: age, sex, previous lung cancer resection, dyspnea (mMRC), right pneumonectomy, and ppo DLCO. The performance parameters of the model adjusted by resampling were: C-statistic 0.712 (95% CI 0.648–0.750), Brier score 0.042 and bootstrap shrinkage 0.854. ConclusionsThe risk prediction model obtained from the GEVATS database is a simple, valid, and reliable model that is a useful tool for establishing the risk of a patient undergoing anatomic lung resection.

Differences in Malnutrition Inflammation Score of Hemodialysis Patients Associated With Hemodialysis Factors. A Spanish Multicenter Epidemiologic Study

The aims of this study are to analyze the prevalence of malnutrition in hemodialysis (HD) patients in Spain, and to assess the association of malnutrition in these patients with sociodemographic characteristics, comorbidity, and parameters related to HD. A multicenter, retrospective, cross-sectional study in HD patients from centers all over Spain was conducted. Nutritional status of patients was assessed using Malnutrition Inflammation Score (MIS), and was stratified according to MIS values into 5 categories: ≤2, normal nutrition; >2 to ≤5, mild malnutrition or risk of malnutrition; >5 to ≤7, moderate malnutrition; >7 to ≤10, severe malnutrition, and >10, extreme malnutrition. A total of 52 Spanish HD Units participated in the study enrolling 2,748 patients. Mean age of patients was 68.20±14.24years, 1,811 (65.9%) were men. Mean time on HD was 55.63±63.25months. Using an MIS cut-off point of 2 for malnutrition, 89% of patients were malnourished (MIS > 2). However, with a cut-off point of 5, more commonly described in the literature, the percentage of patients with malnutrition was reduced to 51.7%. Using this cut-off, we observed significant differences between patients with malnutrition and normo-nourished patients in biochemical parameters, age, Charlson Index, HD residual renal function, scheme, and vascular access (permanent catheter vs arteriovenous fistula). A multivariate regression analysis showed that age, sex, HD scheme, vascular access, residual renal function, and comorbidity index were predictive factors for malnutrition. We found that a high percentage of HD patients with malnutrition did not receive oral supplementation. The prevalence of malnutrition in HD patients in Spain, assessed using the MIS scale, was high. Higher malnutrition was associated with the use of catheter versus fistula, and standard HD versus online hemodiafiltration, and with the absence of residual renal function, older age, greater comorbidity, and male sex. Malnourished patients had a low rate of oral supplementation.

Safety of digoxin in nonagenarian patients with atrial fibrillation: lessons from the Spanish Multicenter Registry.

BACKGROUNDThe association between digoxin and mortality is an unclear issue. In older patients with atrial fibrillation (AF), where use of digoxin is frequent, the evidence of its safety is scarce. Our aim is to assess the safety of digoxin in nonagenarian patients with AF.METHODSWe evaluated data from 795 nonagenarian patients with non-valvular AF from the Spanish Multicenter Registry. We analyzed the relationship between digoxin and all-cause mortality with the Cox proportional-hazards model.RESULTSFollow-up was 27.7 ± 18.3 months. Mean age was 92.5 ± 3.8 years, and 71% of nonagenarian patients were female. Digoxin was not associated with increased risk of mortality [adjusted hazard ratio (aHR) = 1.16, 95% CI: 0.96−1.41,P = 0.130]. However, we found a significant increase in mortality in the subgroup with estimated glomerular filtration rate (eGFR) < 30 mL/min per 1.73 m 2 (aHR = 2.01, 95% CI: 1.13−3.57,P = 0.018), but not in the other subgroups of eGFR (30−59 mL/min per 1.73 m2 and ≥ 60 mL/min per 1.73 m2). When exploring the risk of mortality according to sex, male subgroup was associated with an increase in mortality (aHR = 1.48, 95% CI: 1.02−2.14,P = 0.041). This was not observed in females subgroup (aHR = 1.03, 95% CI: 0.81−1.29,P = 0.829). Based on the presence or absence of heart failure, we did not find significant differences (aHR = 1.20, 95% CI: 0.87−1.65,P = 0.268 vs. aHR = 1.15, 95% CI: 0.90−1.47,P = 0.273, respectively). CONCLUSIONSIn our large registry of nonagenarian patients with AF, we did not find an association between digoxin and mortality in the total sample. However, in the subgroup analyses, we found an increase in mortality with the use of digoxin in men and in patients with an eGFR < 30 mL/min per 1.73 m 2.

Efficacy and safety of oral fosfomycin for asymptomatic bacteriuria in kidney transplant recipients: Results from a Spanish multicenter cohort.

Current guidelines recommend against systematic screening or treating asymptomatic bacteriuria (AB) among kidney transplant (KT) recipients, although the evidence regarding episodes occurring early after transplantation or in the presence of anatomical abnormalities is inconclusive. Oral fosfomycin may constitute a good option for the treatment of post-transplant AB, particularly due to the emergence of multidrug-resistant (MDR) uropathogens. Available clinical evidence supporting its use in this specific setting, however, remains scarce. We performed a retrospective study in 14 Spanish institutions from January 2005 to December 2017. Overall, 137 episodes of AB diagnosed in 133 KT recipients treated with oral fosfomycin (calcium and trometamol salts) with a test-of-cure urine culture within the first 30 days were included. Median time from transplantation to diagnosis was 3.1 months (interquartile range [IQR]: 1.1 - 10.5). Most episodes (96.4% [132/137]) were caused by gram-negative bacteria (GNB), and 56.9% (78/137) were categorized as MDR (extended-spectrum β-lactamase-producing Enterobacterales [20.4%] and carbapenem-resistant GNB [2.9%]). Rate of microbiological failure at month 1 was 40.1% (95% confidence interval [95%CI]: 31.9 - 48.9) for the whole cohort and 42.3% (95%CI: 31.2 - 54.0) for episodes due to MDR pathogens. Previous urinary tract infection (odds ratio [OR]: 2.42; 95%CI: 1.11 - 5.29; P-value = 0.027) and use of fosfomycin as salvage therapy (OR: 8.31; 95%CI: 1.67 - 41.35; P-value = 0.010) were predictors of microbiological failure. No severe treatment-related adverse event were detected. Oral fosfomycin appears to be a suitable and safe alternative for the treatment (if indicated) of AB after KT, including those episodes due to MDR uropathogens.
