Seven- and thirty-day mortality in digoxin poisoning: Results from the DIGITOX study.

BACKGROUND: Digoxin poisonings are relatively common and potentially fatal, requiring immediate therapeutic intervention, with special attention to the patient's hemodynamic status and the presence of electrocardiographic and electrolytic disturbances. OBJECTIVE: To identify factors associated with seven-day and thirty-day mortality in digoxin poisoning. DESIGN, SETTINGS AND PARTICIPANTS: A retrospective, observational, multicenter study was conducted across 15 Hospital Emergency Departments (HED) in Spain. All patients over 18 years of age who presented to participating HEDs from 2015 to 2021 were included. The inclusion criteria encompassed individuals meeting the criteria for digoxin poisoning, whether acute or chronic. OUTCOMES MEASURE AND ANALYSIS: To identify independent factors associated with 7-day and 30-day mortality, a multivariate analysis was conducted. This analysis included variables of clinical significance, as well as those exhibiting a trend (p < 0.1) or significance in the bivariate analysis. MAIN FINDINGS: A total of 658 cases of digoxin poisoning were identified. Mortality rates were 4.5% (30 patients) at seven days and 11.1% (73 patients) at thirty days. Regarding 7-day mortality, the mean age of deceased patients was comparable to survivors (84.7 (8.9) vs 83.9 (7.9) years; p = ns). The multivariate analysis revealed that factors independently associated with 7-day mortality encompassed the extent of dependence assessed by the Barthel Index (BI 60-89 OR 0.28; 95% CI 0.10-0.77; p = 0.014 and BI>90 OR 0.22; 95% CI 0.08-0.63; p = 0.005), the identification of ventricular arrhythmias (OR 1.34; 95% CI 1.34-25.21; p = 0.019), and the presence of circulatory (OR 2.84; 95% CI 1.19-6.27; p = 0.019) and neurological manifestations (OR 2.67; 95% CI 1.13-6.27; p = 0.025). Factors independently associated with 30-day mortality encompassed extent of dependence (BI 60-89 OR 0.37; 95% CI 0.20-0.71; p = 0.003 and BI>90 OR 0.18; 95% CI 0.09-0.39; p < 0.001) and the identification of circulatory (OR 2.13; 95% CI 1.10-4.15; p = 0.025) and neurological manifestations (OR 2.39; 95% CI 1.25-3.89; p = 0.006). CONCLUSIONS: The study identifies the degree of dependency assessed by the Barthel Index and the presence of cardiovascular and neurological symptoms as independent predictors of both 7-day and 30-day mortality. Additionally, the detection of ventricular arrhythmia is also an independent factor for 7-day mortality.

Bronchopulmonary penetration of isavuconazole in lung transplant recipients.

Isavuconazole's (ISA) pharmacokinetics was studied among lung transplant recipients to evaluate its bronchopulmonary penetration. This study included 13 patients and showed mean serum concentrations of 3.30 (standard deviation [SD] 0.45), 5.12 (SD 1.36), and 6.31 (SD 0.95) at 2 h, 4 h, and 24 h respectively. Mean concentrations in the epithelial lining fluid were 0.969 (SD 0.895), 2.141 (SD 1.265), and 2.812 (SD 0.693) at the same time points. ISA is a drug with a tolerable safety profile that achieves adequate concentrations in the lung.

A Retrospective Controlled Cohort Study of the Impact of Glucocorticoid Treatment in SARS-CoV-2 Infection Mortality.

Evidence to support the use of steroids in coronavirus disease 2019 (COVID-19) pneumonia is lacking. We aim to determine the impact of steroid use for COVID-19 pneumonia on hospital mortality. We performed a single-center retrospective cohort study in a university hospital in Madrid, Spain, during March of 2020. To determine the role of steroids in in-hospital mortality, patients admitted with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia and treated with steroids were compared to patients not treated with steroids, and we adjusted with a propensity score for patients on steroid treatment. Survival times were compared using the log rank test. Different steroid regimens were compared and adjusted with a second propensity score. During the study period, 463 out of 848 hospitalized patients with COVID-19 pneumonia fulfilled inclusion criteria. Among them, 396 (46.7%) patients were treated with steroids and 67 patients were not. Global mortality was 15.1%. The median time to steroid treatment from symptom onset was 10 days (interquartile range [IQR], 8 to 13 days). In-hospital mortality was lower in patients treated with steroids than in controls (13.9% [55/396] versus 23.9% [16/67]; hazard ratio [HR], 0.51 [95% confidence interval, 0.27 to 0.96]; P = 0.044). Steroid treatment reduced mortality by 41.8% relative to the mortality with no steroid treatment (relative risk reduction, 0.42 [95% confidence interval, 0.048 to 0.65]). Initial treatment with 1 mg/kg of body weight/day of methylprednisolone versus steroid pulses was not associated with in-hospital mortality (13.5% [42/310] versus 15.1% [13/86]; odds ratio [OR], 0.880 [95% confidence interval, 0.449 to 1.726]; P = 0.710). Our results show that the survival of patients with SARS-CoV-2 pneumonia is higher in patients treated with glucocorticoids than in those not treated. Rates of in-hospital mortality were not different between initial regimens of 1 mg/kg/day of methylprednisolone and glucocorticoid pulses.

Effectiveness, safety and clinical outcomes of direct-acting antiviral therapy in HCV genotype 1 infection: Results from a Spanish real-world cohort.

BACKGROUND & AIMS: Clinical trials evaluating second-generation direct-acting antiviral agents (DAAs) have shown excellent rates of sustained virologic response (SVR) and good safety profiles in patients with chronic hepatitis C virus (HCV) genotype 1 infection. We aimed to investigate the effectiveness and safety of two oral DAA combination regimens, ombitasvir/paritaprevir/ritonavir plus dasabuvir (OMV/PTV/r+DSV) and ledipasvir/sofosbuvir (LDV/SOF), in a real-world clinical practice. METHODS: Data from HCV genotype 1 patients treated with either OMV/PTV/r+DSV±ribavirin (RBV) (n=1567) or LDV/SOF±RBV (n=1758) in 35 centers across Spain between April 1, 2015 and February 28, 2016 were recorded in a large national database. Demographic, clinical and virological data were analyzed. Details of serious adverse events (SAEs) were recorded. RESULTS: The two cohorts were not matched with respect to baseline characteristics and could not be compared directly. The SVR12 rate was 96.8% with OMV/PTVr/DSV±RBV and 95.8% with LDV/SOF±RBV. No significant differences were observed in SVR according to HCV subgenotype (p=0.321 [OMV/PTV/r+DSV±RBV] and p=0.174 [LDV/SOF]) or degree of fibrosis (c0.548 [OMV/PTV/r/DSV±RBV] and p=0.085 [LDV/SOF]). Only baseline albumin level was significantly associated with failure to achieve SVR (p<0.05) on multivariate analysis. Rates of SAEs and SAE-associated treatment discontinuation were 5.4% and 1.7%, in the OMV/PTV/r+DSV subcohort and 5.5% and 1.5% in the LDV/SOF subcohort, respectively. Hepatocellular carcinoma (HCC) recurred in 30% of patients with a complete response to therapy for previous HCC. Incident HCC was reported in 0.93%. CONCLUSIONS: In this large cohort of patients managed in the real-world setting in Spain, OMV/PTV/r+DSV and LDV/SOF achieved high rates of SVR12, comparable to those observed in randomized controlled trials, with similarly good safety profiles. LAY SUMMARY: In clinical trials, second-generation direct-acting antiviral agents (DAAs) have been shown to cure over 90% of patients chronically infected with the genotype 1 hepatitis C virus and have been better tolerated than previous treatment regimens. However, patients enrolled in clinical trials do not reflect the real patient population encountered in routine practice. The current study, which includes almost 4,000 patients, demonstrates comparable rates of cure with two increasingly used DAA combinations as those observed in the clinical trial environment, confirming that clinical trial findings with DAAs translate into the real-world setting, where patient populations are more diverse and complex.

Real-World Effectiveness and Safety of Oral Combination Antiviral Therapy for Hepatitis C Virus Genotype 4 Infection.

Patients with hepatitis C virus (HCV) genotype 4 infection are poorly represented in clinical trials of second-generation direct-acting antiviral agents (DAAs). More data are needed to help guide treatment decisions. We investigated the effectiveness and safety of DAAs in patients with genotype 4 infection in routine practice. In this cohort study, HCV genotype 4-infected patients treated with ombitasvir/paritaprevir/ritonavir (OMV/PTVr) + ribavirin (RBV) (n=122) or ledipasvir/sofosbuvir (LDV/SOF) ± RBV (n=130) included in a national database were identified and prospectively followed up. Demographic, clinical and virologic data and serious adverse events (SAEs) were analyzed. Differences between treatment groups mean that data cannot be compared directly. Overall sustained virologic response at Week 12 post treatment (SVR12) was 96.2% with OMV/PTVr+RBV and 95.4% with LDV/SOF±RBV. In cirrhotic patients, SVR12 was 91.2% with OMV/PTVr+RBV and 93.2% with LDV/SOF±RBV. There was no significant difference in SVR12 according to degree of fibrosis in either treatment group (P = .243 and P = .244, respectively). On multivariate analysis, baseline albumin <3.5 g/dL (OMV/PTVr) and bilirubin >2 mg/dL (both cohorts) were significantly associated with failure to achieve SVR (P < .05). Rates of SAEs and SAE-associated discontinuation were 5.7% and 2.5%, respectively, in the OMV/PTVr subcohort and 4.6% and 0.8%, respectively, in the LDV/SOF subcohort. DAA-based regimens returned high rates of SVR12, comparable to limited data from clinical trials, in cirrhotic and non-cirrhotic HCV genotype 4 patients managed in a realworld setting. Safety profiles of both regimens were good and comparable to those reported for other HCV genotypes.

Prevalence and Risk Factors of Prolonged Corrected QT Interval Among Children and Adolescents Treated With Antipsychotic Medications: A Long-Term Follow-Up in a Real-World Population.

PURPOSE: This study aimed to describe the prevalence of corrected QT (QTc) interval disorders and the possible predisposing factors in children and adolescents treated with antipsychotic (AP) medications in a real-world population with a long-term follow-up. METHODS: Data were obtained from the SafEty of NeurolepTics in Infancy and Adolescence (SENTIA) registry (https://sentia.es). The SENTIA includes patients younger than 18 years who are currently taking or initiating treatment with AP medications and have agreed to participate in the registry. The SENTIA's follow-up includes an electrocardiogram (ECG) assessment before starting treatment and at 1, 3, and 6 months after treatment initiation or after any changes in the patient's AP medication treatment. Thereafter, all participants undergo an ECG every 6 months. A QTc interval more than 450 milliseconds, increases in QTc interval of 60 milliseconds or more, or QTc dispersion more than 100 milliseconds were considered abnormal. RESULTS: Since January 1, 2011, 101 patients have been enrolled in SENTIA and have had at least 1 ECG assessment. The mean age at inclusion was 11.5 years; 75% of the patients were men. The mean follow-up time was 20.0 ± 15.1 months. The most frequently prescribed AP medications were risperidone (52.2%) and aripiprazole (45.5%). Seven patients (6.9%) had abnormal changes in QTc. No patient had a QTc interval more than 500 milliseconds. All patients were asymptomatic. The QTc changes were observed at different times of exposure, with a range of 1 to 39 months after beginning AP treatment. Concomitant use of attention deficit and hyperactivity disorder drugs seemed a possible factor associated with QTc disorders. CONCLUSIONS: Patients should undergo a baseline ECG assessment before starting AP medication treatment, particularly patients with concomitant use of attention deficit and hyperactivity disorder drugs or a family/personal history of heart disease.

Safety and efficacy of triple therapy with peginterferon, ribavirin and boceprevir within an early access programme in Spanish patients with hepatitis C genotype 1 with severe fibrosis: SVRw12 analysis.

BACKGROUND & AIMS: The addition of protease inhibitors (PIs) changed the hepatitis C virus (HCV) treatment standards and improved sustained viral response (SVR) rates in patients with genotype 1 HCV infection. METHODS: Prospective, multicentre, national registry that includes naïve and treatment-experienced patients with HCV genotype 1 infection, who had bridging fibrosis or cirrhosis and were treated with triple therapy (peginterferon alfa-2a or alfa-2b, ribavirin and boceprevir) as compassionate use, and in accordance with the Summary of Product Characteristics. RESULTS: Most of the patients (68.2%) were male, with a mean age of 53 years, 75% (n = 128) had HCV 1b genotype and baseline viral load of 6.2 log. According to prior treatment, 20% of patients were treatment-naïve and 80% had received prior treatment. Approximately 36.5% of patients (n = 62) reported at least one serious adverse events (SAEs) (total SAEs = 103). The most common SAEs were neutropenia (57.6%), anaemia (47.6%) and grade 3 thrombopenia (25.9%). Patients with albumin <3.5 g/dl and bilirubin >2 mg/dl had an increased relative risk (greater than one-fold) for SAEs, including infections and hepatic decompensation. In the intent-to-treat analysis (n = 170), the overall percentage of patients with SVRw12 was 46.5%. In patients with 1 log decrease at week 4 (lead-in phase), the overall SVRw12 rate was 67.0%. In the patients initiating triple therapy with boceprevir (n = 139), the global response rate was 56.4%. In a multivariate analysis, an increased probability of achieving SVR was associated with response to prior treatment (relapsers), >1 log decrease in viral load in the lead-in phase and baseline albumin >3.5 g/dl. CONCLUSIONS: Triple therapy in patients with severe fibrosis/cirrhosis is associated with a higher rate of SAE and a lower rate in comparison with patients with mild disease. However, for patients with intact liver function, it could be considered as a treatment option, when other alternatives would not be available.

Dose increase needed in most cystic fibrosis lung transplantation patients when changing from twice- to once-daily tacrolimus oral administration.

AIM: The aim of this pharmacokinetic (PK) study was to evaluate tacrolimus (TAC) exposure in stable cystic fibrosis (CF) lung transplant (LT) recipients, converted from TAC twice daily to TAC once daily in an open-label, prospective, single-centre study. METHODS: Eligible patients were post-transplant CF patients (18-65 years) with stable lung function, on stable doses of TAC twice daily and who were candidates to switch to TAC once daily. Twelve consecutive patients were included in the study. Patients had their first PK analysis on day 1, still under the stable TAC twice-daily regimen, and were converted to TAC once daily from day 2 onwards. The doses were adjusted according to clinical judgement to achieve target levels, and a second 24-h PK period profile was obtained once the patient was on a stable dosage on the therapeutic range. RESULTS: The mean total (SD) daily dose of TAC twice daily at baseline upon enrolment was 0.17 (0.10) mg/kg/day. The mean (SD) daily dose of TAC once daily after adjustments was 0.22 (0.12) mg/kg/day. In order to achieve target C min levels with a similar AUC0-24, 82% of subjects who were converted to TAC once daily required an increase of dose, in a range of 0-66.7%, with a mean dose increase of 28%. CONCLUSIONS: Our study results indicate that the switch for conversion from TAC twice daily to TAC once daily in patients with CF may need dose adjustment in order to reach levels within the therapeutic target.

Prevalence of Body Dysmorphic Disorder in the Spanish Population: Cross-Sectional Web-Based Questionnaire Study.

BACKGROUND: Body dysmorphic disorder (BDD) is defined as excessive concern with mild or nonexistent defects in personal physical appearance, which are not perceived by others. The worldwide prevalence of BDD ranges between 0.5% and 3.2%, with no differences across genders. The mean age of onset of BDD is 16.9 years. BDD is typically associated with young age, psychiatric disorders, and dermatological procedures. Patients with BDD typically display poorer mental health status than patients diagnosed with other mental disorders. OBJECTIVE: The aim of this study was to estimate the prevalence of BDD in Spain and to identify the variables associated with BDD. METHODS: We performed a cross-sectional descriptive study by collecting data through an anonymous web-based survey targeting the Spanish population aged 18 years or older. The measures in this study were (1) sociodemographic variables, (2) variables associated with dermatological and psychiatric disorders and cosmetic procedures, (3) scales measuring quality of life (12-item Short Form health survey, version 2) and (4) BDD (BDD Questionnaire). Statistical analysis was performed with SPSS software version 21. P values less than .05 were considered significant. RESULTS: Of the 2091 participants who took the survey, 322 (15.2%) met the criteria of having BDD. The mean age of the participants with BDD was 23.5 (SD 9.6) years. In terms of BDD prevalence, women accounted for 19.9% (284/1421), men accounted for 5.2% (34/653), and students accounted for 25.2% (263/1043). Approximately 46.6% (150/322) of the participants with BDD reported a history of psychiatric comorbidities, including anxiety disorders, depressive disorders, and eating disorders. BDD was significantly associated with female gender, younger age (18-24 years), students, monthly income of less than €500 (€1=US $1.11), and the presence of dermatological and some psychiatric disorders such as depression, anxiety, and eating disorders (P<.05). The number of body parts of concern in participants with BDD was significantly higher than that in those without BDD (4.6 vs 2.2, respectively; P<.001). Regarding the body parts of concern, body fat was the most common concern for both groups with BDD and without BDD, followed by thighs, face, hips, and skin in the BDD group and thighs, teeth, and hair in the non-BDD group. Participants with BDD showed a significantly poorer self-perception of their mental health, irrespective of the presence of any mental disorder (P<.001). CONCLUSIONS: Our findings showed that the prevalence of BDD in Spain was higher than expected. Further, BDD is frequently associated with other psychiatric disorders, particularly depressive disorder, anxiety disorder, and eating disorder. Participants with BDD had a poorer perception of quality of life associated with mental but not physical health problems. Finally, the perception of quality of mental health life in participants with BDD was independent of diagnosis of any mental disorder.

Efficacy of amoxicillin/clavulanic acid after surgical drainage of perianal abscess in the prevention of the development of anal fistula (PERIQxA study): study protocol for a multicenter randomized, double-blind clinical trial.

BACKGROUND: Anorectal fistula, which is a relatively common pathology, is the chronic manifestation of the acute perirectal process that forms an anal abscess. The development of a fistula after incision and drainage of an anal abscess is seen in approximately 26-37%. Its treatment is a relevant topic, and the role of the use of antibiotic therapy in its prevention remains controversial, after the publication of several studies with contradictory results and several methodological limitations. Our hypothesis is that the combination of amoxicillin and clavulanic acid will reduce the incidence of anal fistula. METHOD: The aim of this study is to evaluate the efficacy of antibiotherapy after surgical drainage of perianal abscess in the development of perianal fistula. The PERIQxA study is a multicenter, randomized, double-blind controlled trial. The study has been designed to include 286 adult patients who will be randomly (1:1) assigned to either the experimental (amoxicillin/clavulanic acid 875/125 mg TDS for 7 days) or the control arm (placebo). The primary outcome measure is the percentage of patients that develop perianal fistula after surgery and during follow-up (6 months). DISCUSSION: This clinical trial is designed to evaluate the efficacy and safety of amoxicillin/clavulanic in the prevention of perianal fistula. The results of this study are expected to contribute to stablish the potential role of antibiotherapy in the therapeutics for anal abscess. TRIAL REGISTRATION: EudraCT Number: 2021-003376-14.

Clinical features and predictors of delayed neurological syndrome in carbon monoxide poisoning: the AMICO study. / Caracterización clínica y factores predictivos de desarrollo de síndrome neurológico tardío en la intoxicación por monóxido de carbono: estudio AMICO.

OBJECTIVES: To identify predictors for developing delayed neurological syndrome (DNS) after an initial episode of carbon monoxide (CO) poisoning in the interest of detecting patients most likely to develop DNS so that they can be followed. MATERIAL AND METHODS: Retrospective review of cases of CO poisoning treated in the past 10 years in the emergency departments of 4 hospitals in the AMICO study (Spanish acronym for the multicenter analysis of CO poisoning). We analyzed demographic characteristics of the patients and the clinical characteristics of the initial episode. The records of the cohort of patients with available follow-up information were reviewed to find cases of DNS. Data were analyzed by multivariant analysis to determine the relationship to characteristics of the initial exposure to CO. RESULTS: A total of 240 cases were identified. The median (interquartile range) age of the patients was 36.2 years (17.6-49.6 years); 108 patients (45.0%) were men, and the poisoning was accidental in 223 cases (92.9%). The median carboxyhemoglobin concentration on presentation was 12.7% (6.2%-18.7%). Follow-up details were available for 44 patients (18.3%). Eleven of those patients (25%) developed DNS. A low initial Glasgow Coma Scale score predicted the development of DNS with an odds ratio (OR) of 0.61 (95% CI, 0.41-0.92) and an area under the receiver operating characteristic curve of 0.876 (95% CI, 0.761-0.990) (P .001). CONCLUSION: The initial Glasgow Coma Scale score seems to be a clinical predictor of DNS after CO poisoning. We consider it important to establish follow-up protocols for patients with CO poisoning treated in hospital EDs.

OBJETIVO: Identificar factores pronósticos de desarrollo de síndrome neurológico tardío (SNT) después de un episodio inicial de intoxicación por monóxido de carbono (ICO), con el fin detectar precozmente a la población más susceptible y facilitar su acceso a un seguimiento específico. METODO: Revisión retrospectiva de todos los casos de ICO que acudieron a los servicios de urgencias (SU) de 4 hospitales durante los últimos 10 años. Se analizaron datos demográficos y características clínicas en el momento del episodio. En la cohorte de pacientes con datos de seguimiento disponibles, se evaluó la aparición de SNT y su relación con diferentes variables en la exposición inicial al CO a través de técnicas de análisis multivariante. RESULTADOS: Se identificaron 240 pacientes. La mediana de edad fue de 36,2 años (17,6-49,6). De ellos 108 (45,0%) eran hombres y 223 casos (92,9%) fueron accidentales. El nivel medio de COHb fue del 12,7% (6,2-18,7). En 44 (18,3%) episodios se disponía de datos de un seguimiento específico. En esta cohorte, 11 (25%) pacientes desarrollaron SNT. Una puntuación inicial más baja en la Escala Coma de Glasgow (GCS) (OR: 0,61, IC 95%: 0,41-0,92) fue predictor independiente del desarrollo del SNT, con un ABC en la curva COR de 0,876 (IC 95%: 0,761-0,990, p 0,001). CONCLUSIONES: Una puntuación inicial baja en la GCS parece ser un predictor clínico de desarrollo de SNT en la ICO. Dada la incidencia de SNT, consideramos fundamental establecer protocolos de seguimiento específico de estos pacientes tras su asistencia inicial en los SU.

Drug utilization and off-label drug use in Spanish pediatric gastroenterology outpatients.

BACKGROUND AND OBJECTIVES: The clinical use of medicines outside the conditions authorized in their Summary of Product Characteristics (SPC) (off-label use) is a common practice in pediatrics. The aim of the present study was to describe and quantify the medicines received by children attended in the pediatric gastroenterology department, their off-label use, and compliance with accepted rules for said use. METHODS: A retrospective observational study was performed on all of the patients who had their first consultation in pediatric gastroenterology between January 1 and October 31, 2010. All of the clinical information and medicines prescribed were analyzed. Off-label use was defined as the use of medicines in indications not included in the officially approved SPC or in ages not included or recommended in the SPC as well as the use of doses, intervals, or administration routes different from those considered in the SPC. RESULTS: A total of 695 patients (52.8% male) were included, 48.2% younger than 2 years. Two-hundred seven patients (29.8%) received 331 prescriptions. The most commonly used medicines were anti-H2 and proton pump inhibitors. Of all the prescriptions, 33.2% were considered off-label, and up to 47.3% of the prescribed patients had at least 1 medicine under off-label conditions. The medical records contained no documentation on information given to the parents regarding off-label use. CONCLUSIONS: The study found a high percentage of off-label use of medicines in the Pediatric Gastroenterology outpatient setting, especially in children younger than 2 years. Several initiatives were derived from the present study and implemented in our hospital.

The Need for the Closer Monitoring of Novel Drugs in MS: A Siponimod Retrospective Cohort Study (Realhes Study).

BACKGROUND: Severe cases of lymphopenia have been reported during siponimod clinical trials, which may negatively impact its benefit/risk profile. OBJECTIVE: We aimed to evaluate the incidence of lymphopenia following the initiation of siponimod treatment in clinical practice. The secondary objectives included the analysis of factors predisposing to and the clinical relevance of lymphopenia events. METHODS: In this multicenter retrospective cohort study, information collected from the medical records of 129 patients with MS from 15 tertiary hospitals in Spain who initiated treatment with Siponimod were followed-up for at least 3 months, including at least one lymphocyte count evaluation per patient. RESULTS: Of the 129 patients, 121 (93.6%) reported lymphopenia events, including 110 (85.3%) with grade ≤ 3 and 11 (8.5%) with grade 4 lymphopenia, higher than those reported in the pivotal clinical trial (73.3% and 3.3% for grade ≤ 3 and grade 4 lymphopenia, respectively). The study included an unexpectedly high proportion of male subjects (72.9%), which might have led to an underestimation of the actual magnitude of the risk. CONCLUSIONS: In this study, the incidence and severity of lymphopenia after starting siponimod treatment were higher than those reported in previous clinical trials. Therefore, our results reinforce the need for the closer monitoring of novel MS drugs in clinical practice, as well as larger and longer follow-up studies to properly characterize this risk.

Treatment With Adalimumab 80 mg Every Other Week in Inflammatory Bowel Disease: Results of Treatment Intensification in Clinical Practice.

Background: Loss of response to anti-tumor necrosis factor drugs in patients with inflammatory bowel disease (IBD) is frequent and, in case of low drug levels, treatment intensification is recommended. In addition, in cases in which clinical response without attainment of remission (clinical, endoscopic, or radiological), intensification could be justified since higher drug levels are associated with better outcomes. For adalimumab (ADA), the standard intensification regimen is 40 mg every week (ew). Availability of ADA 80 mg prefilled pens has enabled every other week (eow) intensification. We assessed the clinical efficacy of intensification with ADA 80 mg eow. Methods: This retrospective study was conducted at a tertiary hospital in Spain. Patients with IBD receiving maintenance ADA 80 mg eow with clinical, biomarker, and drug-level assessments were included. Demographics and clinical, biological, and endoscopic evaluation of the disease before and after ADA intensification, and pharmacokinetic assessments, were collected. Results: Eighty-seven patients (72 Crohn's disease, 15 ulcerative colitis; average age 50 years) were included. Reasons for ADA intensification were: low ADA levels-<5 µg mL-1-(17%), low ADA levels-<5 µg mL-1-without clinical response (63%), clinical response without clinical remission (15%) and active disease on objective evaluation (including colonoscopy, magnetic resonance imaging, capsule endoscopy, and/or intestinal ultrasound; 5%). Following treatment intensification to ADA 80 mg eow, 75 patients (86%) were in clinical remission and 69 (79.3%) were in biologic remission (clinical remission and normalization of biomarkers). After a median follow-up of 19 months (interquartile range 13-25), 63 patients (72%) remained on treatment and in clinical remission. There were no serious infections, hospitalizations, or deaths. Drug costs did not increase with the 80 mg eow regimen versus a standard intensification regimen. Conclusions: ADA intensification to 80 mg eow was safe, effective, and did not increase drug costs versus standard intensification to 40 mg ew in our experience.

Peginterferon alpha-2a and ribavirin in patients with hepatitis C virus genotype 1 infection with persistently normal alanine aminotransferase levels.

BACKGROUND AND AIM: To evaluate the efficacy and safety of peginterferon α-2a plus ribavirin at standard doses in patients with hepatitis C virus (HVC) genotype 1 infection with persistently normal alanine aminotransferase (ALT) levels. METHODS: Patients aged 18 to 65 years were included in this observational, prospective study if they had evidence of a HCV genotype 1 infection. The serum HCV RNA concentration was determined at baseline and week 12. A qualitative HCV RNA test was performed at baseline and at weeks 48 and 72. Liver function tests were performed at each study visit. The primary efficacy measure was the sustained virological response in the intention-to-treat population. Logistic regression analyses were also performed to explore predictors of virological response. RESULTS: A sustained virological response was observed in 100 of the 175 patients (57%). An early virological response and end-of-treatment response were seen in 159 patients (91%) and 133 patients (76%), respectively. Thirty-seven of the 122 evaluable patients for this outcome (30%) showed a rapid virological response. A higher viral load was a significant predictor for a lack of rapid virological response and lack of sustained virological response. There were not any unexpected safety or tolerability findings. CONCLUSIONS: Our study suggests that the efficacy of the combination of peginterferon α-2a and ribavirin in patients with HCV genotype 1 infection and normal ALT levels is at least similar to that reported in patients with elevated ALT levels.

Nurses competence in the reporting of medication-related incidents: An intervention study.

OBJECTIVES: Less than 5% of all harmful medicine-related incidents (MIs) or adverse drug reactions received by the Spanish Pharmacovigilance system are notified by Registered Nurses (RNs). The main objective of this study was to determine the impact of a multifaceted institutional intervention (MII) in patient safety on the reporting competence of medication incidents of hospital RNs. DESIGN: One-group pre-test-posttest design. SETTING: Tertiary, public, teaching hospital in Spain. PARTICIPANTS: A total of 139 RNs responded to pre- and postintervention questionnaires constituting the paired sample subjected to analysis. INTERVENTION: A MII, consisting of educational activities and materials, change in MI reporting form from paper to electronic and appointment of reporting support services, was designed and directed to all hospital RNs and midwifes. MAIN OUTCOME MEASURES: Overall MIs reporting competence (OC) and its dimensions (attitudes, knowledge and skills) were measured through a synthetic variable (total OC value range: 34-170 points) by means of an electronic questionnaire. RESULTS: A statistically significant 7.96-point increase in OC from baseline to the final measurement was obtained (CI: 5.05-10.85). There was an increase of 7.38 points in the skills dimension (CI: 5.06-9.68). After the MII, 73.4% nurses improved their OC and 33.8% reported at least one no-harm MI postintervention compared to 4.4% pre-intervention (p < .001). A one-point increase in OC improved the probability of becoming reporter by 2.9% and a one-point increase in skills by 6.4%. CONCLUSION: MIs reporting competence among RNs increased after a multifaceted institutional intervention, due to an improvement in the skills dimension. The MII was also effective in raising both, the rate of RNs who become reporters and the number of no-harm MIs reported.

Red blood cell distribution width as a marker of hyperinflammation and mortality in COVID-19.

BACKGROUND: Red blood cell distribution width (RDW) could reflect interleukin-6 (IL-6) systemic activity since anisocytosis represents the inhibition of erythropoiesis, leaded by the hyperinflammatory background. Our objective was to analyze RDW performance to predict outcome in coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS). METHODS: Retrospective observational study including 173 patients with COVID-19-associated ARDS. Data was analyzed at hospital admission, inclusion in the TOCICOV Study (day 0), days 1, 3, 7 and 15 post-inclusion. RESULTS: Overall, 57% patients received tocilizumab. Overall mortality was 20.8%. RDW was higher in non-survivors compared to survivors at admission (13.53% vs. 14.35, P=0.0016), day 0 (13.60% vs. 14.42, P=0.026), day 3 (13.43% vs. 14.36, P<0.001) and day 7 (13.41% vs. 14.31, P=0.046), presenting better discrimination ability for mortality than other prognostic markers [area under the curve-receiver operating characteristic (AUC-ROC) =0.668 for admission RDW, 0.680 for day 0 RDW, 0.695 for day 3 RDW and 0.666 for day 7 RDW]. RDW values did not vary significantly according to tocilizumab treatment. When adjusted by hemoglobin and tocilizumab treatment, only RDW at admission, day 0, day 3 and C reactive protein (CRP) at day 0 and day 1 were associated with mortality (P<0.05). Only in non-tocilizumab treated patients, IL-6 levels at day 0 were correlated with day 3 RDW (r=0.733, P=0.004) and with day 3 CRP (r=0.727, P=0.022). Both parameters showed significant statistical correlation (r=0.255 for day 1 RDW and CRP in the overall cohort and r=0.358 for day 3 RDW and CRP in patients not treated with tocilizumab, P<0.015). CONCLUSIONS: RDW predicts COVID-19-associated ARDS mortality and reflects the hyperinflammatory background and the effects of cytokines such as IL-6, irrespective of tocilizumab treatment.

Bronchopulmonary Penetration of Isavuconazole in Pulmonary Transplant Recipients (PBISA01): Protocol for a Phase IV Clinical Trial With a Single Treatment Arm.

BACKGROUND: Aspergillosis is the most frequently observed invasive fungal disease (IFD) in lung transplant recipients. Isavuconazole (ISA) has shown a better safety profile and noninferiority to voriconazole in the treatment of patients with IFD. OBJECTIVE: The aim of this study is to describe the bronchopulmonary pharmacokinetic profile of oral ISA by analyzing the degree of penetration in the epithelial lining fluid and alveolar macrophages in patients receiving lung transplantation with a diagnosis of IFD. METHODS: A total of 12 patients aged ≥18 years receiving a lung transplant with an IFD diagnosis and indication for ISA treatment and follow-up bronchoscopy will be included in the study. After 5 days of treatment with ISA and before the treatment is discontinued, the patients will be randomized (1:1:1:1) to perform the scheduled bronchoscopy at various times after the administration of ISA (2, 4, 8, and 12 hours). In total, 4 blood samples will be obtained per patient: at 72 hours after treatment initiation, on the day of the bronchoscopy, at the time of the bronchoalveolar lavage (simultaneously), and at 7 days after treatment initiation, to analyze tacrolimus and ISA plasma levels. ISA concentrations will be measured in plasma, epithelial lining fluid, and alveolar macrophages by a high-performance liquid chromatography/UV coupled to fluorescence method. RESULTS: Enrollment for the PBISA01 trial began in October 2020 and was completed in October 2021. All samples will be analyzed once recruitment is complete, and the results are expected to be published in October 2022. CONCLUSIONS: There are no clinical studies that analyze the bronchopulmonary penetration of ISA. Bronchoalveolar lavage performed routinely in the follow-up of lung transplant recipients constitutes an opportunity to analyze the bronchopulmonary penetration of ISA.
