RESUMEN

A 98-year-old woman presented with histologically confirmed locally advanced basal cell carcinoma of the face. A multidisciplinary approach excluded surgery because of the site near sensitive organs, extension, age, and comorbidities. Patient and caregivers declined radiotherapy considering the necessity of multiple hospital appointments. The patient was then placed on therapy with sonidegib, an oral inhibitor of the Hedgehog signaling pathway. There was a very rapid clinical response after only 28 days of treatment. The basal cell carcinoma improved progressively, with no adverse events reported. This case illustrates the efficacy and safety of this treatment in an advanced age patient. This treatment had a remarkably positive impact on quality of life, including that of the caregivers.

RESUMEN

BACKGROUND: Clinical trials have provided evidence that transplants of dopaminergic precursors, which may be replaced by new in vitro stem cell sources, can integrate into the host tissue, and alleviate motor symptoms in Parkinson´s disease (PD). In some patients, deterioration of graft function occurred several months after observing a graft-derived functional improvement. Rejection of peripheral organs was initially related to HLA-specific antibodies. However, the role of non-HLA antibodies is now considered also relevant for rejection. Angiotensin-II type-1 receptor autoantibodies (AT1-AA) act as agonists of the AT1 receptors. AT1-AA are the non-HLA antibodies most widely associated with graft dysfunction or rejection after transplantation of different solid organs and hematopoietic stem cells. However, it is not known about the presence and possible functional effects of AT1-AA in dopaminergic grafts, and the effects of treatment with AT1 receptor blockers (ARBs) such as candesartan on graft survival. METHODS: In a 6-hydroxydopamine PD rat model, we studied the short-term (10 days)- and long-term (3 months) effects of chronic treatment with the ARB candesartan on survival of grafted dopaminergic neurons and microglial graft infiltration, as well as the effects of dopaminergic denervation and grafting on serum and CSF AT1-AA levels. The expression of AT1 receptors in grafted neurons was determined by laser capture microdissection. RESULTS: At the early period post-grafting, the number of grafted dopaminergic neurons that survived was not significantly different between treated and untreated hosts (i.e., control rats and rats treated with candesartan), probably because, just after grafting, other deleterious factors are predominant for dopaminergic cell death, such as mechanical trauma, lack of growth factors/nutrients and ischemia. However, several months post-grafting, we observed a significantly higher number of surviving dopaminergic neurons and a higher density of striatal dopaminergic terminals in the candesartan-treated group. For several months, grafted rats showed blood and cerebrospinal fluid levels of AT1-AA higher than normal controls, and also higher AT1-AA levels than non-grafted parkinsonian rats. CONCLUSIONS: The results suggest the use of ARBs such as candesartan in PD patients, particularly before and after dopaminergic grafts, and the need to monitor AT1-AA levels in PD patients, particularly in those candidates for dopaminergic grafting.

RESUMEN

Basal cell carcinoma (BCC) is highly curable by surgical excision or radiation. In rare cases, BCC can be locally destructive or difficult to surgically remove. Hedgehog inhibition (HHI) with vismodegib or sonidegib induces a 50-60% response rate. Long-term toxicity includes muscle spasms and weight loss leading to dose decreases. This retrospective chart review also investigates the impact of CoQ10 and calcium supplementation in patients treated with HHI drugs at a single academic medical center from 2012 to 2022. We reviewed the charts of adult patients diagnosed with locally advanced or metastatic BCC treated with vismodegib or sonidegib primarily for progression-free survival (PFS). Secondary objectives included overall survival, BCC-specific survival, time to and reasons for discontinuation, overall response rate, safety and tolerability, use of CoQ10 and calcium supplements, and insurance coverage. Of 55 patients assessable for outcome, 34 (61.8%) had an overall clinical benefit, with 25 (45.4%) having a complete response and 9 (16.3%) a partial response. Stable disease was seen in 14 (25.4%) and 7 (12.7%) progressed. Of the 34 patients who responded to treatment, 9 recurred. Patients who were rechallenged with HHI could respond again. The median overall BCC-specific survival rate at 5 years is 89%. Dose reductions or discontinuations for vismodegib and sonidegib occurred in 59% versus 24% of cases, or 30% versus 9% of cases, respectively. With CoQ10 and calcium supplementation, only 17% required a dose reduction versus 42% without. HHI is highly effective for treating advanced BCC but may require dosing decreases. Sonidegib was better tolerated than vismodegib. CoQ10 and calcium supplementation can effectively prevent muscle spasms.

RESUMEN

We aimed in this study to investigate the possible cardioprotective effects of sacubitril/valsartan against sunitinib-induced cardiac fibrosis (CF) and oxidative stress via targeting thioredoxin-interacting protein/thioredoxin (TXNIP/TRX) system and nuclear factor-kappa B (NF-κB)/Wingless-related MMTV integration site (Wnt)/ß-catenin/Sex-determining region Y box 9 (SOX9) signaling. CF was induced in male Wistar albino rats by cumulative dose of sunitinib (300 mg/kg, given over 4 weeks as: 25 mg/kg orally, three times a week), which were co-treated with sacubitril/valsartan (68 mg/kg/day, orally) for four weeks. Significant elevation in blood pressure, cardiac inflammatory and fibrotic markers besides cardiac dysfunction were observed. These alterations were associated with disruption of TXNIP/TRX system, upregulation of NF-κB/Wnt/ß-catenin/SOX9 pathway along with marked increase in lysyl oxidase (LOX) and matrix metalloproteinase-1 (MMP-1) expressions and extensive deposition of collagen fibers in cardiac tissues. Luckily, sacubitril/valsartan was able to reverse all of the aforementioned detrimental effects in sunitinib-administered rats. These findings illustrate a potential role of sacubitril/valsartan in alleviating CF and oxidative stress induced by sunitinib via antioxidant, anti-inflammatory and antifibrotic properties. These remarkable effects of sacubitril/valsartan were mediated by its ability to improve TXNIP/TRX system and downregulate NF-κB/Wnt/ß-catenin/SOX9 signaling in addition to decreasing LOX and MMP-1 expressions in cardiac tissues. In summary, this study highlights sacubitril/valsartan as a potential therapeutic agent in mitigating CF and oxidative stress especially in cancer cases treated with sunitinib.

RESUMEN

Lung cancer is a serious health issue globally, and current treatments have proven to be inadequate. Therefore, immune checkpoint inhibitors (ICIs) that target the PD-1/PD-L1 pathway have become a viable treatment option in lun cancer. Honokiol, a lignan derived from Magnolia officinalis, has been found to possess anti-inflammatory, antioxidant, and antitumor properties. Our research found that honokiol can effectively regulate PD-L1 through network pharmacology and transcriptome analysis. Cell experiments showed that honokiol can significantly reduce PD-L1 expression in cells with high PD-L1 expression. Molecular docking, cellular thermal shift assay (CETSA) and Bio-Layer Interferometry (BLI)indicated that Honokiol can bind to PD-L1. Co-culture experiments on lung cancer cells and T cells demonstrated that honokiol mediates PD-L1 degradation, stimulates T cell activation, and facilitates T cell killing of tumor cells. Moreover, honokiol activates CD4 + and CD8 + T cell infiltration in vivo, thus suppressing tumor growth in C57BL/6 mice. In conclusion, this study has demonstrated that honokiol can inhibit the growth of lung cancer by targeting tumor cell PD-L1, suppressing PD-L1 expression, blocking the PD-1/PD-L1 pathway, and enhancing anti-tumor immunity.

RESUMEN

Sacubitril/Valsartan, the combination of angiotensin receptor inhibitor and neprilysin inhibitor, is now becoming the class 1 recommendation for HFrEF. Some studies have shown the positive effect of Sacubitril/Valsartan on HFrEF cancer patients, while there is devoid of evidence about the effect of this drug in aged cancer patients with HFmrEF and HFpEF. By searching the patients with a diagnosis of both cancer and Heart failure (HF) over 65, the patients who had received treatment with Sacubitril/Valsartan were selected as the candidates for Sacubitril/Valsartan group, and the patients who had received conventional HF therapy without Sacubitril/Valsartan were chosen as the control group. Data were collected for up to 9 months. We filtered 38 patients and 50 patients valid for Sacubitril/Valsartan group and control group, respectively. After initiation of heart failure management, our study found a better cardiac condition in Sacubitril/Valsartan group, having better LVEF, LVFS, NT-proBNP in 3rd, 6th, 9th month (P < .05) and better NYHA function classification after the treatment. We also observed fewer cases of deterioration on LAD (P = .029) and LVEDD (P = .023) in Sacubitril/Valsartan group. In subgroup analysis, our study showed that all 3 kinds of HF patients had better LVEF, LVFS, and NT-proBNP in Sacubitril/Valsartan group (P < .05). Our study further indicated that Sacubitril/Valsartan can improve cardiac function and benefit cardiac remolding in aged cancer patients of all 3 kinds of HF. This is the first study to provide new evidence for the use of Sacubitril/Valsartan in aged cancer patients of 3 kinds of HF.

RESUMEN

OBJECTIVE: This study aimed to determine the evolution of sacubitril-valsartan research and analyze the publications quantitatively and qualitatively. MATERIALS AND METHODS: We used the bibliometric method and a combination of CiteSpace_6.1.6 and VOSviewer_1.6.18 to identify top authors, countries, institutions, co-cited articles, co-cited journals, keywords, and trends. This study prioritized key aspects in the existing global research on Entresto (Sacubitril/Valsartan) to assess our depth of knowledge in this field and identify potential insights. The objective was to generate a reference for the utilization of the "angiotensin receptor-neprilysin inhibitor" (ARNI). RESULTS: From 2008 to 2022, citations of sacubitril-valsartan showed an upward trend. VOSviewer keyword analysis of 3,408 publications identified 624 keywords and divided them into seven different clusters. The clustered network was constructed based on 1,191 references cited by 3,408 publications that met the terms, where the clustered network of sacubitril-valsartan was presented. These publications can be regarded as fundamental to Entresto's research. Analysis of co-cited reference clusters showed that other than Entresto's novel application in other diseases, the new combination with other medication or mechanical assistance therapies against heart failure was Entresto's latest focus. Analysis of citation bursts showed that the rank of the top 25 keywords, according to the chronological sequence, marked Entresto's research entering a new era of exploring the extended application in other diseases and novel combinations with other diverse therapies. CONCLUSIONS: We found that emerging new mechanisms in sacubitril-valsartan therapy intended for more targets in the pathogenesis of specific diseases will be the focus of further studies.

RESUMEN

BACKGROUND: Increasing arterial stiffness is a prominent feature of the aging cardiovascular system. Arterial stiffening leads to fundamental alterations in central hemodynamics with widespread detrimental implications for organ function resulting in significant morbidity and death, and specific therapies to address the underlying age-related structural arterial remodeling remain elusive. The present study investigates the potential of the recently clinically available dual angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril/valsartan (LCZ696) to counteract age-related arterial fibrotic remodeling and stiffening in 1-year-old mice. METHODS AND RESULTS: Treatment of in 1-year-old mice with ARNI (sacubitril/valsartan), in contrast to angiotensin receptor blocker monotherapy (valsartan) and vehicle treatment (controls), significantly decreases structural aortic stiffness (as measured by in vivo pulse-wave velocity and ex vivo aortic pressure myography). This phenomenon appears, at least partly, independent of (indirect) blood pressure effects and may be related to a direct antifibrotic interference with aortic smooth muscle cell collagen production. Furthermore, we find aortic remodeling and destiffening due to ARNI treatment to be associated with improved parameters of cardiac diastolic function in aged mice. CONCLUSIONS: This study provides preclinical mechanistic evidence indicating that ARNI-based interventions may counteract age-related arterial stiffening and may therefore be further investigated as a promising strategy to improve cardiovascular outcomes in the elderly.

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) is the most common cancer in the Caucasian population. It has a multifactorial pathogenesis, in which constitutive activation of the Sonic Hedgehog signalling (SHH) pathway (via mutations in PTCH1 or SMO genes) represents by far the most common genetic aberration. The introduction of vismodegib and sonidegib, two SHH pathway inhibitors, changed the therapeutic approach of locally advanced and metastatic BCCs. EADO's (European Association of Dermato-Oncology) new staging system refers to these as 'difficult-to-treat' BCCs. OBJECTIVE: The aim was to evaluate sonidegib's effectiveness in patients affected by difficult-to-treat BCCs by using non-invasive diagnostic techniques. METHODS: We retrospectively evaluated 14 patients (4 females, 10 males; mean age 77 ± 11 years) affected by difficult-to-treat BCCs treated with oral sonidegib 200 mg/day that were followed with total body videodermoscopy (V-Track, Vidix 4.0) and dynamic optical coherence tomography (D-OCT, VivoSight Dx) since May 2022. Considering the risk of rhabdomyolysis routine blood tests, especially for creatine kinase concentrations, were performed. All treated patients were inserted in the BasoCare database, which aims to offer support to patients taking sonidegib. Complete and partial responses were evaluated by the overall reduction of the number of lesions and their individual sizes. Safety was evaluated by assessing the occurrence and severity of adverse reactions. RESULTS: Eighty per cent achieved complete clearance and 75% reduction of diameter. D-OCT scans performed at every follow-up showed concordance with clinical appearance and demonstrated reduction of hyporeflective structures, that is, islets of tumour cells and overall improvement of morphology. CONCLUSION: Sonidegib can be considered an effective treatment option in cases where surgery or radiotherapy would be unfeasible or has previously failed, although pigmented lesions did not show complete clearance, suggesting that there are factors other than the SHH pathway involved in tumour growth. Videodermoscopy and D-OCT were useful in the quick and seamless follow-up of lesions and added valuable information in assessing efficacy.

RESUMEN

BACKGROUND: Sacubitril/valsartan, a new pharmacological class of angiotensin receptor neprilysin inhibitor, is beneficial to heart failure through blocking the degradation of natriuretic peptides and inhibiting renin-angiotensin-aldosterone system (RAAS) activation which also relate to the pathophysiologic mechanisms of chronic kidney disease (CKD). However, its effects on CKD remain unclear. To assess the efficacy and safety of sacubitril/valsartan for patients with CKD, we performed this meta-analysis. METHODS: The Embase, PubMed and the Cochrane Library were searched for randomized controlled trials (RCTs) that compared sacubitril/valsartan with ACEI/ARBs in patients with CKD whose estimated glomerular filtration rate (eGFR) was below 60 mL/min/1.73 m2. We adopted the Cochrane Collaboration tool for assessing the risk of bias. The effect size was estimated using the odds ratio (OR) with 95% confidence interval (CI). RESULTS: Six trials with a total of 6217 patients with CKD were included. In terms of cardiovascular events, sacubitril/valsartan attenuated the risk of cardiovascular death or heart failure hospitalization (OR: 0.68, 95% CI 0.61-0.76, P < 0.00001, I2 = 43%). With respect to renal function, sacubitril/valsartan prevented the incidence of serum creatinine (Scr) elevation among patients with CKD (OR: 0.79, 95% CI 0.67-0.95, P = 0.01, I2 = 0%). Subgroup analysis about eGFR demonstrated that with long follow-up, sacubitril/valsartan significantly decreased the number of patients with more than 50% reduction in eGFR compared with ACEI/ARBs (OR: 0.52, 95% CI 0.32-0.84, P = 0.008, I2 = 9%). In patients with CKD, the incidence of end-stage renal disease (ESRD) was reduced with sacubitril/valsartan treatment, despite no statistically significant difference between the two groups (OR: 0.59, 95% CI 0.29-1.20, P = 0.14, I2 = 0%). As for the safety, we found that sacubitril/valsartan was associated with the occurrence of hypotension (OR: 1.71, 95% CI 1.15-2.56, P = 0.008, I2 = 51%). However, there was no trend towards increasing the risk of hyperkalemia in patients who received sacubitril/valsartan (OR: 1.09, 95% CI 0.75-1.60, P = 0.64, I2 = 64%). CONCLUSION: This meta-analysis indicated that sacubitril/valsartan improved renal function and conferred effective cardiovascular benefits in patients with CKD, without serious safety issues being observed. Thus, sacubitril/valsartan may be a promising option for patients with CKD. Certainly, further large-scale randomized controlled trials are needed to confirm these conclusions.

RESUMEN

Basal cell carcinoma accounts for 75% of skin cancers worldwide and is the most common malignancy in Caucasians. Since chronic ultraviolet exposure is the major risk factor for its development, sun-exposed areas such as the face are frequently affected. The gold-standard treatment is surgical excision. Radiotherapy may be considered in selected cases such as unresectable primary tumors. In some patients, when the risk of a significant functional/cosmetic deficit advises against both surgery and radiotherapy, target therapy (hedgehog pathway inhibitors) can be administered alone or in a neoadjuvant setting, to reduce the tumor size and make it eligible for surgery. Vismodegib as a neoadjuvant treatment before surgery has been investigated in a single, multicentre, open-label, phase II trial (VISMONEO); however, sonidegib has not yet been evaluated in this setting. We report the cases of two patients with locally advanced basal cell carcinoma of the face who achieved complete remission with sonidegib followed by a more limited surgical excision than would have been needed without target therapy.

RESUMEN

BACKGROUND: Valsartan was recalled by the US Food and Drug Administration in July 2018 for carcinogenic impurities, resulting in a drug shortage and management challenges for valsartan users. The influence of the valsartan recall on clinical outcomes is unknown. We compared the risk of adverse events between hypertensive patients using valsartan and a propensity score-matched group using nonrecalled angiotensin receptor blockers and angiotensin-converting enzyme inhibitors. METHODS AND RESULTS: We used Optum's deidentified Clinformatics Datamart (July 2017-January 2019). Hypertensive patients who received valsartan or nonrecalled angiotensin receptor blockers/angiotensin-converting enzyme inhibitors for 1 year before and on the recall date were compared. Primary outcomes were measured in the 6 months following the recall and included: (1) a composite measure of all-cause hospitalization, all-cause emergency department visit, and all-cause urgent care visit, and (2) a composite cardiac event measure of hospitalizations for acute myocardial infarction and hospitalizations/emergency department visits/urgent care visits for stroke/transient ischemic attack, heart failure, or hypertension. We compared the risk of outcomes between treatment groups using Cox proportional hazard models. Of the hypertensive patients, 76 934 received valsartan, and 509 472 received a nonrecalled angiotensin receptor blocker/angiotensin-converting enzyme inhibitor. Valsartan use at the time of recall was associated with a higher risk of all-cause hospitalization, emergency department use, or urgent care use (hazard ratio [HR], 1.02 [95% CI, 1.00-1.04]) and the composite of cardiac events (HR, 1.22 [95% CI, 1.15-1.29]) within 6 months after the recall. CONCLUSIONS: The valsartan recall and shortage affected hypertensive patients. Local- and national-level systems need to be enhanced to protect patients from drug shortages by providing safe and reliable medication alternatives.

RESUMEN

Despite the demonstrated advantages of angiotensin receptor/neprilysin inhibitors in the management of heart failure, the pivotal Angiotensin-Neprilysin Inhibition versus Enalapril in Heart Failure (PARADIGM-HF) trial, which explored this class of medications, did not include individuals from Saudi Arabia. Recognizing that different nations and ethnic groups may exhibit unique characteristics, this study aimed to compare the demographics and outcomes of patients in Saudi Arabia who received sacubitril/valsartan (Sac/Val) with those enrolled in the PARADIGM-HF trial. In this retrospective, multicenter cohort study, we included all adult patients diagnosed with heart failure with reduced ejection fraction (HFrEF) within a tertiary healthcare system in Saudi Arabia between January 2018 and December 2021 and were initiated on Sac/Val. The primary objective was to compare the patient characteristics of those initiating Sac/Val treatment with the participants in the PARADIGM-HF trial. The secondary endpoints included the initiation setting, dose initiation, and titration, as well as alterations in B-type natriuretic peptide and ejection fraction at the 6-month mark. Furthermore, we reported the hospitalization and mortality event rates at the 12-month time point. The study included 400 patients with HFrEF receiving Sac/Val. Compared with the PARADIGM-HF trial, the cohort had a younger mean age and a higher prevalence of diabetes mellitus. SAC/VAL was prescribed as the initial therapy for 34% of the patients, while the remaining participants were initially treated with either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker before transitioning to Sac/Val. Approximately 75% of patients were initiated on 100 mg Sac/Val twice daily, and 90% initiated therapy in the inpatient setting. The mean ejection fraction significantly improved from 26.5 ±â€…8.4% to 30.5 ±â€…6.4% at 6 months (P < .001), while the median B-type natriuretic peptide level change was not significant (P = .39). Our study revealed notable disparities in the baseline characteristics of patients with HFrEF compared with those in the PARADIGM-HF trial. These findings offer valuable real-world insights into the prescription patterns and outcomes of Sac/Val in patients with HFrEF in Saudi Arabia, an aspect not previously represented in the PARADIGM-HF study.

RESUMEN

In patients with heart failure (HF), the neuroendocrine systems of the sympathetic nervous system (SNS), the renin-angiotensin-aldosterone system (RAAS) and the arginine vasopressin (AVP) system, are activated to various degrees producing often-observed tachycardia and concomitant increased systemic vascular resistance. Furthermore, sustained neurohormonal activation plays a key role in the progression of HF and may be responsible for the pathogenetic mechanisms leading to the perpetuation of the pathophysiology and worsening of the HF signs and symptoms. There are biomarkers of activation of these neurohormonal pathways, such as the natriuretic peptides, catecholamine levels and neprilysin and various newer ones, which may be employed to better understand the mechanisms of HF drugs and also aid in defining the subgroups of patients who might benefit from specific therapies, irrespective of the degree of left ventricular dysfunction. These therapies are directed against these neurohumoral systems (neurohumoral antagonists) and classically comprise beta blockers, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers and vaptans. Recently, the RAAS blockade has been refined by the introduction of the angiotensin receptor-neprilysin inhibitor (ARNI) sacubitril/valsartan, which combines the RAAS inhibition and neprilysin blocking, enhancing the actions of natriuretic peptides. All these issues relating to the neurohumoral activation in HF are herein reviewed, and the underlying mechanisms are pictorially illustrated.

RESUMEN

Heart failure is an increasing public health issue with substantial morbidity and mortality rates. This study aimed to evaluate the efficacy, safety, and long-term outcomes of angiotensin receptor neprilysin inhibitor (ARNi) in the treatment of heart failure with reduced ejection fraction (HFrEF) 5 years after treatment initiation. This retrospective study analyzed a cohort of 75 patients diagnosed with HFrEF over a period of 5 years after the initiation of ARNi therapy. The initial clinical condition, laboratory and echocardiographic measurements including left ventricular ejection fraction (LVEF), New York Heart Association functional classes (NYHA-FC) and the prognostic nutritional index were compared to the corresponding values obtained after a 5-year period of ARNi therapy. In addition, the number of annual hospitalizations, mortality rates and any history of adverse effects during the follow-up period were recorded. The N-terminal pro-brain natriuretic peptide (NT-proBNP) level, LVEF, and NYHA-FC values demonstrated significant improvement at the end of the 5-year follow-up period (all parameters, P < .001). Although the observed increase in the prognostic nutritional index was not statistically significant (P = .077), it is worth noting. A significant reduction in daily diuretic doses and hospitalizations due to heart failure was observed following the use of ARNi (all comparisons, P < .001). The prevalence of hypotension was around 16% (being symptomatic in 4%), making it the most frequently observed adverse event. The 5-year cardiovascular mortality rate was 17.3%. The use of ARNi in HFrEF patients was associated with a notable improvement in NYHA-FC, LVEF, and NT-proBNP levels in the long-term, while also leading to a better nutritional status and reduced need for diuretics and annual hospitalization. Additionally, ARNi usage has been associated with improved nutritional status, decreased reliance on diuretics, and reduced frequency of annual hospitalizations. These effects were associated with a lack of significant increase in adverse effects. These results may contribute to a better understanding of ARNi's long-term effects on patient outcomes.

RESUMEN

This study aimed to evaluate the efficacy of nifedipine controlled-release tablets combined with sacubitril valsartan in diabetic nephropathy (DN) patients with hypertension. One hundred and twelve DN patients with hypertension were enrolled. They were randomly divided into the control group (treated with nifedipine controlled-release tablets combined with valsartan) and the observation group (treated with nifedipine controlled-release tablets combined with sacubitril valsartan). Renal function, endothelial function and inflammatory response were examined. After three-months treatment, the levels of clinical indexes (glycosylated hemoglobin, fasting blood glucose, systolic and diastolic blood pressure), renal function indicators (urinary albumin excretion rate, blood urea nitrogen, serum creatinine and cystatin C), endothelial function indicators (microalbumin, angiotensin II, thrombomodulin and cartilage oligomeric matrix protein) and inflammatory response factors (interleukin-6 and tumor necrosis factor-α) in the observation group were significantly lower than those in the control group. Nifedipine controlled-release tablets combined with sacubitril valsartan could effectively alleviate the progression of DN combined with hypertension.

RESUMEN

BACKGROUND: Sonidegib is approved to treat locally advanced basal cell carcinoma (laBCC) in patients not amenable to surgery or radiation. The BOLT trial demonstrated durable efficacy of sonidegib in laBCC patients over 42 months. BCC is most common in the elderly, who often take chronic medications. OBJECTIVES: We evaluated the efficacy of sonidegib (200 mg daily) in laBCC patients on select concomitant medications. MATERIALS & METHODS: In the Phase II BOLT study, laBCC patients were randomized 1:2 to sonidegib 200 mg:800 mg daily. The primary endpoint was objective response rate (ORR) per central review. Post hoc assessments included ORR and duration of response (DOR) per investigator review for patients on concomitant medications. RESULTS: At 42 months, ORR for laBCC patients taking sonidegib 200 mg daily (n=66) was 71.2% and DOR was 15.7 months according to investigator review. Patients on select concomitant medications (n=37) had an ORR of 73.0%; DOR was not estimable. CONCLUSION: Administration of sonidegib with concomitant medications, excluding strong cytochrome P450 3A4/5 inhibitors/inducers, does not appear to alter its efficacy in laBCC patients.

RESUMEN

AIMS: Adrenomedullin is a vasodilatory peptide with a role in microcirculatory and endothelial homeostasis. Adrenomedullin is a substrate for neprilysin and may therefore play a role in beneficial effects of sacubitril/valsartan (Sac/Val) treatment. METHODS AND RESULTS: Mid-regional pro-adrenomedullin (MR-proADM) was measured in 156 patients with heart failure with reduced ejection fraction (HFrEF) treated with Sac/Val and 264 patients with heart failure with preserved ejection fraction (HFpEF) randomized to treatment with Sac/Val or valsartan. Echocardiography and Kansas City Cardiomyopathy Questionnaire results were collected at baseline and after 6 and 12 months in the HFrEF cohort. Median (Q1-Q3) baseline MR-proADM concentrations were 0.80 (0.59-0.99) nmol/L in HFrEF and 0.88 (0.68-1.20) nmol/L in HFpEF. After 12 weeks of treatment with Sac/Val, MR-proADM increased by median 49% in HFrEF and 60% in HFpEF, while there were no significant changes in valsartan-treated patients (median 2%). Greater increases in MR-proADM were associated with higher Sac/Val doses. Changes in MR-proADM correlated weakly with changes in N-terminal pro-B-type natriuretic peptide, cardiac troponin T and urinary cyclic guanosine monophosphate. Increases in MR-proADM were associated with decreases in blood pressure, but not significantly associated with changes in echocardiographic parameters or health status. CONCLUSIONS: MR-proAD concentrations rise substantially following treatment with Sac/Val, in contrast to no change from valsartan. Change in MR-proADM from neprilysin inhibition did not correlate with improvements in cardiac structure and function or health status. More data are needed regarding the role of adrenomedullin and its related peptides in the treatment of heart failure.

RESUMEN

Sacubitril/valsartan (SAC/VAL), an angiotensin receptor blocker-neprilysin inhibitor, has been widely used to treat several types of heart failure. Nevertheless, the effects of drugs in mitral regurgitation patients, from the molecular level to therapeutic effects, remain unclear. This study investigates the roles of SAC/VAL on cardiac function, mitochondrial quality, autophagy, mitophagy, and natriuretic peptides in a rat model of chronic mitral regurgitation. Male Sprague-Dawley rats underwent MR induction (n = 16) and sham surgeries (n = 8). Four weeks post-surgery confirmed MR rats were randomly divided into MR (n = 8) and SAC/VAL (n = 8) groups. The SAC/VAL group was administered SAC/VAL, whereas the MR and the sham rats received vehicle via oral gavage daily for 8 weeks. Cardiac geometry, function, and myocardial fibrosis were assessed by echocardiography and histopathology. Spectrophotometry and real-time PCR were performed to assess the pharmacological effects on mitochondrial quality, autophagy, mitophagy, and natriuretic peptides. MR rats demonstrated significant left heart dilation and left ventricular systolic dysfunction compared with the sham group, which could be significantly improved by SAC/VAL. In addition, SAC/VAL significantly reduced myocardial cardiac remodeling and fibrosis in MR rats. SAC/VAL improved the mitochondrial quality by attenuating mitochondrial reactive oxygen species production and mitochondrial depolarization compared with the MR group. Also, the upregulation of autophagy-related, mitophagy-related, and natriuretic peptide system gene expression in MR rats was attenuated by SAC/VAL treatment. In conclusion, this study demonstrated that SAC/VAL treatment could provide numerous beneficial effects in MR conditions, suggesting that this drug may be an effective treatment for MR.

RESUMEN

PURPOSE: Sacubitril/valsartan is a mainstay of the treatment of heart failure with reduced ejection fraction (HFrEF); however, its effects on exercise performance yielded conflicting results. Aim of our study was to evaluate the impact of sacubitril/valsartan on exercise parameters and echocardiographic and biomarker changes at different drug doses. METHODS: We prospectively enrolled consecutive HFrEF outpatients eligible to start sacubitril/valsartan. Patients underwent clinical assessment, cardiopulmonary exercise test (CPET), blood sampling, echocardiography, and completed the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Sacubitril/valsartan was introduced at 24/26 mg b.i.d. dose and progressively uptitrated in a standard monthly-based fashion to 97/103 mg b.i.d. or maximum tolerated dose. Study procedures were repeated at each titration visit and 6 months after reaching the maximum tolerated dose. RESULTS: Ninety-six patients completed the study, 73 (75%) reached maximum sacubitril/valsartan dose. We observed a significant improvement in functional capacity across all study steps: oxygen intake increased, at peak exercise (from 15.6 ± 4.5 to 16.5 ± 4.9 mL/min/kg; p trend = 0.001), while minute ventilation/carbon dioxide production relationship reduced in patients with an abnormal value at baseline. Sacubitril/valsartan induced positive left ventricle reverse remodeling (EF from 31 ± 5 to 37 ± 8%; p trend < 0.001), while NT-proBNP reduced from 1179 [610-2757] to 780 [372-1344] pg/ml (p trend < 0.0001). NYHA functional class and the subjective perception of limitation in daily life at KCCQ-12 significantly improved. The Metabolic Exercise Cardiac Kidney Index (MECKI) score progressively improved from 4.35 [2.42-7.71] to 2.35% [1.24-4.96], p = 0.003. CONCLUSIONS: A holistic and progressive HF improvement was observed with sacubitril/valsartan in parallel with quality of life. Likewise, a prognostic enhancement was observed.
