Introduction and objectives Optimal medical therapy decreases mortality and heart failure (HF) hospitalizations in HF patients with reduced left ventricular ejection fraction. Women have been underrepresented in clinical trials and not specifically evaluated. This study aimed to compare the safety and effectiveness of drug titration in women vs men. Methods This post hoc gender study of the ETIFIC multicenter randomized trial included hospitalized patients with new-onset HF with reduced ejection fraction and New York Heart Association II-III and no contraindications to beta-blockers. A structured 4-month titration process was implemented in HF clinics. The primary endpoint was the mean relative dose (% of target dose) of beta-blockers achieved by women vs men. Secondary endpoints included the mean relative doses of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and mineralocorticoid receptor antagonists, adverse events, and other clinical outcomes at 6 months. Results A total of 320 patients were included, 83 (25.93%) women and 237 (74.06%) men (76 vs 213 analyzed). The mean±standard deviation of the relative doses achieved by women vs men were as follows: beta-blockers 62.08%±30.72% vs 64.4%±32.77%, with a difference of−2.32% (95%CI,−10.58-5.94), P = .580; and mineralocorticoid receptor antagonists 79.85%±27.72% vs 67.29%±31.43%, P =.003. No other differences in drug dosage were found. Multivariate analysis showed nonsignificant differences. CV mortality was 1 (1.20%) vs 3 (1.26%), P=1, and HF hospitalizations 0 (0.00%) vs 10 (4.22%), P=.125. Conclusions In a post hoc analysis from the HF-titration ETIFIC trial, we found nonsignificant gender differences in drug dosage, cardiovascular mortality, and HF hospitalizations (AU)

RESUMO

Objetivos: Describir las características clínicas y el manejo terapéutico y determinar los eventos cardiovasculares tras un año de seguimiento en una población contemporánea con insuficiencia cardíaca (IC) con y sin diabetes tipo 2 en España. También se analizó en la población DAPA-HF (pacientes que cumplieron la mayoría de los criterios de inclusión del estudio DAPA-HF) y en los pacientes tratados basalmente con inhibidores SGLT2.Métodos: Estudio observacional, retrospectivo, poblacional, empleando la base de datos BIG-PAC. La fecha índice fue 1 de enero de 2019. Se seleccionaron sujetos≥18 años que recibieron tratamiento por IC en 2019. Se analizaron los eventos durante 2019.Resultados: Se identificaron 21.851 pacientes con IC (78±11,3 años; 53% varones; 50,9% IC con fracción de eyección reducida; 44,5% en clase funcional NYHA II). La prevalencia de IC fue del 1,88% y la incidencia 2,83 por 1.000 pacientes-año. El 66,1% tomaba inhibidores del sistema renina-angiotensina, el 69,4% betabloqueantes, el 31,2% antialdosterónicos y el 7,5% sacubitrilo/valsartán. Durante el año de seguimiento, el 29,8% fue hospitalizado por descompensación de la IC (tiempo medio primer evento 120,9±72,5 días), un 12,3% murieron, un 8,1% murieron durante la hospitalización. Los eventos fueron más frecuentes en los pacientes con diabetes tipo 2. Las hospitalizaciones por IC fueron más comunes en la población similar a DAPA-HF.Conclusiones: En España, la población con IC es anciana y tiene muchas comorbilidades. Aproximadamente la mitad de los pacientes tienen IC con fracción de eyección reducida. Existe margen de mejora en el manejo de la IC, en particular mediante el empleo de aquellos fármacos que reducen tanto la hospitalización por IC como la mortalidad, para disminuir la carga de IC (AU)


Objective: This work aims to describe the clinical characteristics and therapeutic management and to determine cardiovascular outcomes after one year of follow-up in a contemporaneous population with heart failure (HF) with and without type 2 diabetes in Spain. These factors were also analyzed in the DAPA-HF-like population (patients who met most inclusion criteria of the DAPA-HF trial) and in patients treated with SGLT2 inhibitors at baseline.Methods: This work is an observational, retrospective, population-based study using the BIG-PAC database. The index date was January 1, 2019. People aged≥18 years who received care for HF in 2019 were selected. Events that occurred in 2019 were analyzed.Results: We identified 21,851 patients with HF (age 78.0±11.3 years, 53.0% men, 50.9% with HF with reduced left ventricular ejection fraction, 44.5% in NYHA functional class II). HF prevalence was 1.88% and incidence was 2.83 per 1,000 person-years. Regarding HF treatments, 66.1% were taking renin-angiotensin system inhibitors, 69.4% beta blockers, 31.2% aldosterone antagonists, and 7.5% sacubitril/valsartan. During the year of follow-up, 29.8% had HF decompensation which led to hospitalization (mean time to first event of 120.9±72.5 days), 12.3% died, and 8.1% died during hospitalization. Events were more common among patients with type 2 diabetes. Hospitalizations for HF were more common in the DAPA-HF-like population.Conclusions: In Spain, the population with HF is elderly and has many comorbidities. Approximately half of patients have HF with reduced left ventricular ejection fraction. There is room for improvement in HF management, particularly through the use of drugs that reduce both HF hospitalization and mortality, in order to reduce the burden of HF (AU)

RESUMO

La insuficiencia cardiaca (IC) constituye actualmente uno de los problemas sociosanitarios más importantes en nuestro país, con una prevalencia en continuo crecimiento. Los avances en el conocimiento de las distintas respuestas biológicas que favorecen el remodelado cardiaco y de la congestión venopulmonar constituyen la base del tratamiento actual. En este artículo elaborado por miembros de los grupos de IC de las sociedades españolas de Cardiología y Medicina Interna se comentan las estrategias terapéuticas actuales para el paciente congestivo refractario a tratamiento diurético, introduciendo nuestra experiencia clínica con el uso de tolvaptán como tratamiento adicional en la congestión asociada a hiponatremia. Para ello se propone un algoritmo sobre el uso de tolvaptán en pacientes con IC congestiva, natremia inferior a 130mEq/l y mala respuesta al tratamiento diurético convencional (AU)


Heart failure (HF) is currently one of the most significant healthcare problems in Spain and has a continuously increasing prevalence. Advances in our understanding of the various biological responses that promote cardiac remodelling and pulmonary venous congestion constitute the basis of current treatment. This article, prepared by members of the HF groups of the Spanish Society of Cardiology and the Spanish Society of Internal Medicine, discusses the current therapeutic strategies for patients with congestion refractory to diuretic treatment. The article includes our clinical experience with the use of tolvaptan as an additional treatment for congestion associated with hyponatraemia. To this end, we propose an algorithm for the use of tolvaptan in patients with congestive HF, natraemia <130mEq/l and poor response to conventional diuretic treatment (AU)

RESUMO

El déficit de hierro en los pacientes con insuficiencia cardiaca es un problema médico que últimamente suscita un interés particular. Esto se debe a la publicación de varios ensayos clínicos que demuestran que la administración de hierro intravenoso en estos pacientes mejora su capacidad funcional, e incluso reduce los ingresos por descompensación de insuficiencia cardiaca. Sin embargo, la aplicación de la evidencia aportada por estos estudios en la práctica clínica es aún controvertida, tanto en los criterios diagnósticos del déficit de hierro, absoluto y funcional, como en la forma óptima de reposición del hierro. Este artículo es un documento de consenso que integra las recomendaciones de las Sociedades Españolas de Medicina Interna y Cardiología en el que se revisa la evidencia científica y se propone un protocolo de actuación diagnóstica y terapéutica del déficit de hierro en la insuficiencia cardiaca (AU)


Iron deficiency in patients with heart failure is a medical problem of recent particular interest. This interest has resulted from the publication of several clinical trials that demonstrated that the administration of intravenous iron to such patients improved their functional capacity and even reduced the number of hospitalisations for heart failure decompensation. However, applying the evidence from these studies in clinical practice is still controversial, both in terms of the diagnostic criteria for iron deficiency (absolute and functional) and the optimal method for iron replenishment. This article is a consensus document that integrates the recommendations of the Spanish Society of Internal Medicine and the Spanish Society of Cardiology. The article reviews the scientific evidence and proposes a diagnostic and therapeutic performance protocol for iron deficiency in heart failure (AU)

RESUMO

Cytomegalovirus (CMV) infection remains a major complication of solid organ transplantation. Because of management of CMV is variable among transplant centers, in 2011 the Spanish Transplantation Infection Study Group (GESITRA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) developed consensus guidelines for the prevention and treatment of CMV infection in solid organ transplant recipients. Since then, new publications have clarified or questioned the aspects covered in the previous document. For that reason, a panel of experts revised the evidence on CMV management, including immunological monitoring, diagnostics, prevention, vaccines, indirect effects, treatment, drug resistance, immunotherapy, investigational drugs, and pediatric issues. This document summarizes the recommendations.

RESUMO

Treatment of solid-organ transplant (SOT) patients with ganciclovir (GCV)-valganciclovir (VGCV) according to the manufacturer's recommendations may result in over- or underexposure. Bayesian prediction based on a population pharmacokinetics model may optimize GCV-VGCV dosing, achieving the area under the curve (AUC) therapeutic target. We conducted a two-arm, randomized, open-label, 40% superiority trial in adult SOT patients receiving GCV-VGCV as prophylaxis or treatment of cytomegalovirus infection. Group A was treated according to the manufacturer's recommendations. For group B, the dosing was adjusted based on target exposures using a Bayesian prediction model (NONMEM). Fifty-three patients were recruited (27 in group A and 26 in group B). About 88.6% of patients in group B and 22.2% in group A reached target AUC, achieving the 40% superiority margin (P< 0.001; 95% confidence interval [CI] difference, 47 to 86%). The time to reach target AUC was significantly longer in group A than in group B (55.9 ± 8.2 versus 15.8 ± 2.3 days,P< 0.001). A shorter time to viral clearance was observed in group B than in group A (12.5 versus 17.6 days;P= 0.125). The incidences of relapse (group A, 66.67%, and group B, 9.01%) and late-onset infection (group A, 36.7%, and group B, 7.7%) were higher in group A. Neutropenia and anemia were related to GCV overexposure. GCV-VCGV dose adjustment based on a population pharmacokinetics Bayesian prediction model optimizes GCV-VGCV exposure. (This study has been registered at ClinicalTrials.gov under registration no. NCT01446445.).

RESUMO

A multicenter cross-sectional study was conducted to determine the current heart transplant (HTx) outcomes in Spain. Clinical and functional status, health-related quality of life (HRQoL), social support, and caregiver burden were analyzed in 303 adult transplant recipients (77.9% males) living with one functioning graft. Mean age at time of HTx (SD) was 56.4 (11.4) years, and the reason for transplantation in all patients was congestive heart failure. All patients had received a first heart transplant 6 (± 1), 12 (± 2), 36 (± 6), 60 (± 10), or 120 (± 20) months previously. Participants completed the Kansas City Cardiomyopathy Questionnaire (KCCQ), the EQ-5D, the Duke-UNC Functional Social Support Questionnaire, and the Zarit Caregiver Burden Scale. Reasonable HRQoL, social support, and caregiver burden levels were found at all time points, although a slight decrease in HRQoL was recorded at 120 months (p ≤ 0.033). Multivariate regression analyses showed that complications, comorbidities, and hospitalizations were associated with HRQoL (EQ-5D: 48.4% of explained variance, F4,164 = 38.46, p < 0.001; KCCQ overall summary score: 45.0%, F3,198 = 54.073, p < 0.001). Patient functional capabilities and complications affected caregiver burden (p < 0.05). In conclusion, HTx patients reported reasonable levels of HRQoL with low caregiver burden. Clinical variables related to these outcomes included functional status, complications, and number of admissions.

RESUMO

Donor-transmitted malaria is a rare complication in solid organ transplantation, which causes high mortality. Data concerning the use of artesunate in solid organ transplant recipients are lacking. We report a heart transplant patient who developed donor-derived severe Plasmodium falciparum malaria, successfully treated with artesunate. Transmission of malaria to 2 of the other transplant recipients from the same donor was also documented.

RESUMO

INTRODUCTION: The use of proliferation signal inhibitors (PSIs) for calcineurin-inhibitor (CNI) minimization or conversion protocols has been promoted for heart transplantation (HT) in the contexts of renal insufficiency, cardiac allograft vasculopathy (CAV), or malignancy. We evaluated our experience with conversion of patients from a CNI-based to a PSI-based immunosuppressive regimen. We focused on improvement in renal function. METHODS: This prospective follow-up included 96 HT patients converted to a PSI-based regimen from 2001 to 2010. We evaluated changes in creatinine clearance (CrCl) prior to at 1 year and at the end of follow-up after conversion. RESULTS: Ninety-six patients including 86% men showed a mean age of 62 ± 8 years. They were converted to a PSI-based regimen at 6.3 ± 4 years post-HT due to the following causes: CNI toxicity (45%), CAV (16%), cancer (16%), CNI toxicity + CAV (17%), or CNI toxicity + cancer (6%). CNI withdrawal was achieved in 77 cases (80%) and minimization in 19 (20%). Everolimus was used in 54 (56%) and sirolimus in 42 (44%) cases. Median follow-up time was 3.8 years. PSI discontinuation due to side effects was common (38%). There were 43 deaths mainly due to cancer and CAV. CrCl improved albeit not significantly in the withdrawal group from a median of 51 mL/min preconversion to 59 mL/min at the last follow-up (P = .12). In the minimization group, median CrCl worsened from a median of 61 mL/min preconversion to 51 mL/min at the last follow-up (P = .001). In the 58 cases (61%) of CNI nephrotoxicity, median CrCl improved from a median of 41 mL/min preconversion to 49 mL/min at the last follow-up (P = .04). CONCLUSION: Despite high rates of discontinuation of PSIs during long-term follow-up, the conversion regimen seemed to be useful to diminish CNI-related renal insufficiency especially with CNI withdrawal.

RESUMO

Ganciclovir-resistant (GanR) cytomegalovirus (CMV) infection after organ transplantation is emerging as a significant therapeutic challenge. We report two cases of GanR CMV infection successfully managed by switching immunosuppression from calcineurin inhibitors to an mTOR inhibitor-based regimen. This salvage therapy should be considered when other options are not available.

RESUMO

Chronic renal failure (CRF) due to calcineurin inhibitor (CNI) nephrotoxicity is a frequent complication among heart transplant (HT) recipients. Small studies have suggested that the introduction of mycophenolate mofetil (MMF) can help to reduce CNI doses thereby to maintaining or improving renal function. We conducted a 4-year, prospective, multicenter study in 89 maintenance HT recipients at 5.6 ± 2.7 years postgrafting who displayed CRF (serum creatinine > 1.4 mg/dL) and were undergoing treatment with cyclosporine and prednisone ± azathioprine. We introduced MMF and reduced cyclosporine to level below 100 ng/mL. Creatinine clearance (CrCl), acute rejection episodes, and survival were through retrospectively compared with a contemporary cohort of HT recipients who were not treated with MMF (control group; n = 38). After conversion to MMF, a rapid increase was observed in the CrCl, which was maintained over the follow-up: namely, CrCl at month 6 and at 4 years were 51.0 ± 15.6 and 54.1 ± 15.6 mL/min versus 41.9 ± 11.1 mL/min at baseline (P < .0001). No renal function changes were observed among the control group. Acute rejection rates were 5.6% and 2.6% in the MMF versus control groups (P = NS) with 4-year survivals >85%. In conclusion, the introduction of MMF allowed a safe reduction of cyclosporine and significantly improved renal function after 4 years.

RESUMO

BACKGROUND: The objectives of this epidemiological, prospective study were to describe the characteristics of cytomegalovirus (CMV) infection in heart transplant (HT) recipients and to identify the variables that may influence the development of CMV viremia and CMV disease in these patients. METHODS: HT recipients ≥18 years of age (n=199) were included in the study. Variables studied included CMV serostatus, immunosuppressive treatment, and administration of anti-CMV prophylaxis. RESULTS: The mean age of the population was 52 years, and 84% were males. Immunosuppressive regimens were administered as induction therapy to 92.5% of patients; 88.5% of patients received calcineurin inhibitors as maintenance therapy. Anti-CMV treatment was given to 59% of 199 patients as prophylaxis (70%), preemptive therapy (10%), or to treat CMV infection (20%). Overall, 43% of patients had at least 1 positive viremia test. No patient with a high-risk serostatus (donor+/recipient-) receiving prophylaxis developed CMV syndrome, and only 2.5% of 199 patients developed CMV invasive disease. Multivariate analysis showed that having a positive donor CMV serostatus was associated with an increased risk of developing CMV viremia (P<0.012), while use of mammalian target of rapamycin (mTOR) inhibitors was associated with a decreased risk (P=0.005). CONCLUSIONS: In a population of HT recipients, the CMV infection rate was similar to that seen in previous studies, but the progression to overt CMV disease was very low. Having a CMV-positive donor was identified as an independent risk factor for developing CMV viremia, while the use of mTOR inhibitors was protective against viremia.

RESUMO

INTRODUCTION: The incidence of skin cancer in heart transplant (HT) patients is higher than in the general population, reversing the proportion of cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with a predominance of the former. The etiologic role of new immunosuppressants is not well known. We sought to ascertain the incidence of SCC and BCC in HT patients and the risk factors for its occurrence. PATIENTS AND METHODS: We report the incidence of all types of post-HT skin cancer, SCC, and BCC among adult HT patients in Spain (4089 subjects) as well as the influence of gender, age at heart transplant, immunosuppression, and sunlight exposure. RESULTS: The incidence rates of SCC and BCC, per 1000 persons/year, were 8.5 and 5.2, respectively. Males had a higher risk of SCC but not BCC. Induction therapy increased the risk of SCC and BCC. The relative risk of mycophenolate mofetil (MMF) was 0.3 (0.2-0.6; P<.0005) and azathioprine (AZA) 1.8 (1.2-2.7; P<.0032) for SCC, whereas tacrolimus and cyclosporine showed no difference. The relative risk of BCC was not affected by any immunosuppressant. CONCLUSION: Age at transplantation>45 years, induction therapy use, and high sunshine zone were risk factors for both SCC and BCC. Different immunosuppressive agents have different risks of nonmelanoma skin cancer, as AZA increases the risk of SCC and MMF is a protective factor. The relative risk of BCC was not affected by any immunosuppressor.

RESUMO

Oral (p.o.) or intravenous (IV) ganciclovir (GCV) has been the first-line agent for prevention and treatment of cytomegalovirus (CMV) infection and disease in solid organ transplantation (SOT). The introduction of p.o. valganciclovir, with higher bioavailability than p.o. GCV, has proven to be a suitable approach toward outpatient p.o. therapy for CMV infection/disease. The present single-arm, exploratory pilot trial performed with 21 patients investigates the efficacy and safety of a short therapeutic course (21 days) based on an initial IV treatment with GCV (5 mg/kg twice daily, for 5 days) followed by p.o. valganciclovir (900 mg twice daily, for 16 days) for CMV infection/disease in SOT patients. In all cases, doses were adjusted for renal function. Moreover, the study allowed comparison of exposure to GCV after p.o. valganciclovir with respect to IV GCV in the same patients. Response to treatment was monitored until day 180. Viral load eradication was achieved in 66.7% of patients, on day 21. Although not statistically significant, a trend was seen toward increased persistence of viral load on day 21 for patients with donor positive/recipient negative CMV serostatus or receiving either anti-rejection therapy or polyclonal anti-thymocyte globulin. CMV clinical infection recurred in 14.3% of patients, with higher recurrence rates in patients with risk factors for persistence of viremia. Exposures to GCV after using IV GCV or p.o. valganciclovir showed comparable values (P=0.054). This short course, combining initial IV GCV and subsequent p.o. valganciclovir, may provide effective exposure and therapeutic response in the treatment of CMV infection in SOT patients with adequate drug exposure and with the additional potential benefit of shortening the length of hospital stay, which may result in cost reduction and improved patient comfort.
