Cabotegravir and Rilpivirine Long-Acting Antiretroviral Therapy Administered Every 2 Months is Cost-Effective for the Treatment of HIV-1 in Spain

Adherence; Antiretroviral therapy; HIVAdherència; Teràpia antiretroviral; VIHAdherencia; Terapia antirretroviral; VIHIntroduction Current antiretroviral therapies (ARTs) have improved outcomes for people living with HIV. However, the requirement to adhere to lifelong daily oral dosing may be challenging for some people living with HIV, leading to suboptimal adherence and therefore reduced treatment effectiveness. Treatment with long-acting (LA) ART may improve adherence and health-related quality of life. The objective of this study was to evaluate the cost-effectiveness of cabotegravir + rilpivirine (CAB+RPV) LA administered every 2 months (Q2M) compared with current ART administered as daily oral single-tablet regimens (STRs) from a Spanish National Healthcare System perspective. Methods A hybrid decision-tree and Markov state-transition model was used with pooled data from three phase III/IIIb trials (FLAIR, ATLAS, and ATLAS-2M) over a lifetime horizon, with health states defined by viral load and CD4+ cell count. Direct costs (in €) were taken from Spanish public sources from 2021 and several deterministic and probabilistic analyses were carried out. An annual 3% discount rate was applied to both costs and utilities. Results Over the lifetime horizon, CAB+RPV LA Q2M was associated with an additional 0.27 quality-adjusted life years (QALYs) and slightly greater lifetime costs (€4003) versus daily oral ART, leading to an incremental cost-effectiveness ratio of €15,003/QALY, below the commonly accepted €30,000/QALY willingness-to-pay threshold in Spain. All scenario analyses showed consistent results, and the probabilistic sensitivity analysis showed cost-effectiveness compared with daily oral STRs in 62.4% of simulations, being dominant in 0.3%. Conclusion From the Spanish National Health System perspective, CAB+RPV LA Q2M is a cost-effective alternative compared with the current options of daily oral STR regimens for HIV treatment.This study, including the journal’s Rapid Service fee, was funded by ViiV Healthcare, Durham, NC, USA

Fascin-1 is released from proximal tubular cells in response to calcineurin inhibitors (CNIs) and correlates with isometric vacuolization in kidney transplanted patients

Fascin-1; Nephrotoxicity; TransplantFascina-1; Nefrotoxicitat; TrasplantamentFascina-1; Nefrotoxicidad; TrasplanteImmunosuppression based on calcineurin inhibitors (CNIs) has greatly improved organ transplantation, although subsequent nephrotoxicity significantly hinders treatment success. There are no currently available specific soluble biomarkers for CNI-induced nephrotoxicity and diagnosis relies on renal biopsy, which is costly, invasive and may cause complications. Accordingly, identification of non-invasive biomarkers distinguishing CNI-induced kidney tubular damage from that of other etiologies would greatly improve diagnosis and enable more precise dosage adjustment. For this purpose, HK-2 cells, widely used to model human proximal tubule, were treated with CNIs cyclosporine-A and FK506, or staurosporine as a calcineurin-independent toxic compound, and secretomes of each treatment were analyzed by proteomic means. Among the differentially secreted proteins identified, only fascin-1 was specifically released by both CNIs but not by staurosporine. To validate fascin-1 as a biomarker of CNI-induced tubular toxicity, fascin-1 levels were analyzed in serum and urine from kidney-transplanted patients under CNIs treatment presenting or not isometric vacuolization (IV), which nowadays represents the main histological hallmark of CNI-induced tubular damage. Patients with chronic kidney disease (CKD) and healthy volunteers were used as controls. Our results show that urinary fascin-1 was only significantly elevated in the subset of CNI-treated patients presenting IV. Moreover, fascin-1 anticipated the rise of sCr levels in serially collected urine samples from CNI-treated pulmonary-transplanted patients, where a decline in kidney function and serum creatinine (sCr) elevation was mainly attributed to CNIs treatment. In conclusion, our results point towards fascin-1 as a putative soluble biomarker of CNI-induced damage in the kidney tubular compartment

Post-mortem findings in Spanish patients with COVID-19; a special focus on superinfections

IntroductionWhole-body autopsies may be crucial to understand coronavirus disease 2019 (COVID-19) pathophysiology. We aimed to analyze pathological findings in a large series of full-body autopsies, with a special focus on superinfections. MethodsThis was a prospective multicenter study that included 70 COVID-19 autopsies performed between April 2020 and February 2021. Epidemiological, clinical and pathological information was collected using a standardized case report form. ResultsMedian (IQR) age was 70 (range 63.75-74.25) years and 76% of cases were males. Most patients (90%,) had at least one comorbidity prior to COVID-19 diagnosis, with vascular risk factors being the most frequent. Infectious complications were developed by 65.71% of the patients during their follow-up. Mechanical ventilation was required in most patients (75.71%) and was mainly invasive. In multivariate analyses, length of hospital stay and invasive mechanical ventilation were significantly associated with infections (p = 0.036 and p = 0.013, respectively). Necropsy findings revealed diffuse alveolar damage in the lungs, left ventricular hypertrophy in the heart, liver steatosis and pre-infection arteriosclerosis in the heart and kidneys. ConclusionOur study confirms the main necropsy histopathological findings attributed to COVID-19 in a large patient series, while underlining the importance of both comorbid conditions and superinfections in the pathology

Epidemiological trends of HIV/HCV coinfection in Spain, 2015-2019

Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population.This work was supported in part by the Spanish AIDS Research Network (RD16/0025/0017, RD16/0025/0018), which is included in the Spanish I+D+I Plan and is co-funded by the ISCIII-Subdirección General de Evaluación and European Funding for Regional Development (FEDER).

Un siglo de luz : Historia empresarial de Iberdrola

El libro se divide en épocas y, dentro de cada una de ellas, se analizan los avatares de las tres empresas fundadoras de Iberdrola. La parte I tiene carácter de introducción y sus dos capítulos responden al deseo de integrar la historia de Iberdrola, tanto en el sector eléctrico espafíol como en el de otros países de Europa. La parte II abarca hasta el afío 1944, fecha de la fusión entre Saltos del Duero e Hidroeléctrica Ibérica. La parte III comprende los afíos 1944-1973, con la crisis energética como límite diferenciador. La parte IV comprende desde el comienzo de la crisis hasta la fusión de Iberduero e Hidrola, en 1991. La última parte del libro, en la que se hace la historia reciente de la empresa, ha sido escrita por sus principales protagonistas, lo cual afíade un interés muy especial a los capítulos catorce, quince y dieciséis, con los que termina la obra
