Areas covered: This review summarizes current evidences about HBV reactivation risk in patients undergoing rituximab-based treatments and appropriate options of antiviral prophylaxis with lamivudine, entecavir or tenofovir, as well as pre-emptive strategy in HBsAg-negative/HBcAb-positive patients. Moreover previous experiences with IFN-based AT as well as recent studies with DAAs in HCV-associated indolent lymphomas or diffuse large B-cell lymphoma (DLBCL) are reviewed.
Expert opinion: Entecavir or tenofovir prophylaxis is recommended for HBsAg-positive patients, while universal prophilaxis with lamivudine may be preferred in HBsAg-negative/anti-HBc-positive patients. In asymptomatic patients with HCV-associated indolent lymphoma DAA-based AT should be used as first-line option, while in DLBCL its deliver after immunochemotherapy-induced complete remission is suggested. 相似文献
Areas covered: We consider the effects of statins on microalbuminuria, proteinuria, glomerular filtration rate, AKI associated with angiography or percutaneous coronary intervention and on CVD event rates in patients with CKD.
Expert opinion: Current evidence points towards the need to prescribe high-potency statins in patients with CKD, before a major decline in kidney function occurs. This may reduce CVD risk and delay the progress of CKD. Administration of either atorvastatin or rosuvastatin can prevent contrast-induced AKI before angiography or percutaneous coronary intervention. The combination of simvastatin + ezetimibe may decrease vascular events in patients with advanced CKD. 相似文献
Areas covered: The aim of this systematic review is to analyze the experimental and early investigational therapies currently under evaluation in this field. Data from completed clinical trials were retrieved from the currently available scientific literature and from the ClinicalTrials.gov website.
Expert opinion: Among the drugs currently being explored, mammalian target of rapamycin inhibitors reduce kidney volume enlargement but their role remains uncertain. The most promising drug is the V2 receptor antagonist tolvaptan, which reduces the increased rate of total kidney volume and slows down glomerular filtration rate decline. The main candidates for the treatment of cysts growth, both in the kidney and in the liver whenever present, are the somatostatin analogues, such as lanreotide and octreotide and more recently pasireotide. As for other therapies, some favorable results have been achieved but data are still not sufficient to establish if these approaches may be beneficial in slowing ADPKD progression in the future. 相似文献
Methods: This study included 60 patients [mean age of 33.97 ± 6.70 years and treated with VPA (n = 24) or CBZ (n = 36) for mean duration of treatment of 6.03 ± 2.81years. Measurements of serum creatinine (sCr), urinary creatinine, creatinine clearance (CrCl) and serum kidney injury molecule 1 (KIM-1), markers of renal dysfunction/injury were done.
Results: Compared to controls, patients had higher sCr, KIM-1 and lower CrCl levels. Compared to patients on VPA, those on CBZ had relatively higher KIM-1 and lower CrCl levels. We reported only significant correlations between KIM-1 with sCr (r = 0.324, p = 0.001) and duration of treatment with AEDs (r = 0.301, p = 0.02).
Conclusion: Chronic VPA and CBZ therapy may be associated with subclinical renal glomerular and/or proximal tubular dysfunctions or injuries. The treating neurologist have to consider this while selection of AED on start treating patients or modifying the AED for patients at high risk of kidney injury. 相似文献
Areas covered: This review will serve to highlight the various pharmacotherapies available to clinicians for patients with HCV recurrence post-liver transplant. A brief history of prior regimens is provided with evidence for newer treatments presented. Also detailed are updated guidelines from societal organizations. Finally, timing of HCV treatment is discussed as the decision to treat patients in a pre or post-liver transplant setting remains challenging.
Expert opinion: While there are many potential available therapies for HCV recurrence in the post-liver transplant setting, daclatasvir/sofosbuvir and ledipasvir/sofosbuvir have been the most extensively studied. Newer, pangenotypic generation drugs require more evidence before routine utilization in post-liver transplant recipients. 相似文献
Areas covered: Data have been extracted from the most important published clinical trials, cumulative real-world experience reports and data from the most relevant studies presented in the last international meetings (European and American International Liver Congresses). In addition, data from the recently updated international guidelines have also been included.
Expert opinion: Although there are many differences in health-care budgets among countries in the world which will surely compromise drug availability and treatment decisions, this review aims to give a general and brief recommendation to help treating physicians to choose the best option to treat hepatitis C. 相似文献
Areas covered: This review covers the mechanism of action, pharmacokinetics, clinical applications, efficacy, and safety profile of glecaprevir/pibrentasvir. It also covers key phase 2 and 3 clinical trials that led to licensure of this regimen.
Expert opinion: Glecaprevir/pibrentasvir is the latest antiviral regimen licensed in the United States for treatment of HCV infection. Although several other direct-acting antiviral agents (DAAs) are currently available, glecaprevir/pibrentasvir has some unique characteristics that expand treatment options for HCV infection, including patients with comorbidities such as advanced stage CKD or prior treatment failure to antiviral regimens containing other DAAs. 相似文献
Areas covered: We review the evidence for existing glucose-lowering treatments in the prevention of DKD, and research into techniques to better target individuals who will benefit from these therapies.
Expert opinion: Diabetic patients with established kidney disease may benefit from glucose-lowering treatment, particularly if a safer side-effect profile of these treatments is achieved. Better understanding of glucose homeostasis and evaluation of compounds inhibiting its downstream effects are required in order to improve the outlook for individuals with DKD. An additional approach to improve the success rate of glucose-lowering treatment is to improve the selection of individuals who may benefit from treatment. A potential means to identify such subjects could involve the use of biomarkers. 相似文献
Areas covered: This review highlights the current treatment options for people with DKD with a particular focus on angiotensin pathway blockade and the potential use of sodium glucose linked transporter 2 (SGLT2) inhibitors. These treatments are associated with an initial decrease in glomerular filtration rate (GFR) and albuminuria; there is also attention on renal hyperfiltration as therapeutic target. Both clinical and preclinical testing are facilitated by leveraging albuminuria reduction as a dynamic biomarker of drug effect linked to renal failure. It is critical to ensure that animal models exhibit both albuminuria and progressive loss of renal function so drug effects can be established in both.
Expert opinion: New pathways and potential drug targets are emerging from gene expression profiling of human kidney biopsies and genome wide association studies. By harmonizing animal experimentation endpoints with clinical outcomes, focusing on disease pathophysiology and incorporating novel gene expression and biomarker changes, therapeutics can be advanced into clinical testing with greater confidence. 相似文献
Areas covered: In this review, the authors look at drugs in early development for the treatment of HCV-related hepatic fibrosis. Their mechanism of action is based on the inhibition of hepatic inflammation, the modulation of cellular sources of extracellular matrix (ECM), the stimulation of ECM degradation and prevention of collagen crosslinking. Importantly, significant antifibrotic effects have been demonstrated with both IFN-based and IFN-free anti-HCV regimens.
Expert opinion: Successful future therapy is likely to be based on sequential administration of drugs leading initially to HCV clearance, followed by treatment for the possible reversal of liver fibrosis. The primary consideration with clinical trials carried out in patients with advanced liver disease is safety. Indeed, the evaluation of anti-fibrotic therapy depends on reliable noninvasive techniques for quantification of liver fibrosis, such as transient or shear-wave elastography or serologic tests which are able to replace liver biopsy. 相似文献
Areas covered: The present review summarizes DCV key pharmacokinetic features and results from Phase II and III trials, discussing also NS5A resistance. Main literature articles have been identified through Pubmed and Medline search; moreover, abstracts from recent international meetings on liver disease have been scrutinized.
Expert opinion: DCV in combination with other DAAs has provided IFN-free regimens with increased efficacy and tolerability. However, suboptimal barrier to resistance and the rapid development of new second-generation NS5A inhibitors will probably make DCV a relatively short-lived drug. 相似文献
Areas covered: This review evaluates the aspects underlying the benefit of treating chronic HCV infection at the early stage of disease. It outlines the considerations that have to be taken into account when planning treatment in patients with HCV and minimal liver disease, assessing the positive reflex of viral eradication on several HCV-associated extra-hepatic conditions such as the risk of lymphoma, insulin-resistance and glycaemic control, and renal function. Lastly, it also covers the improvement of patients’ quality of life and the pharmaco-economic aspects associated with early treatment.
Expert commentary: Treatment of patients with HCV and minimal liver disease is associated with a beneficial, pleiotropic effect of viral eradication that goes beyond the simplistic consideration of the improvement in liver disease-related outcomes. 相似文献
Areas covered: Available data on epidemiology, type, and possible risk factors for nephrotoxicity of sofosbuvir-containing treatment are reviewed. Related articles were collected by searching Scopus, Pubmed, and Science direct. Search terms were ‘sofosbuvir’, ‘nephrotoxicity’, ‘acute kidney injury’, ‘renal impairment’, and “direct acting antiviral agents.
Expert commentary: AKI may happen in 1–15% of patients who are treated with sofosbuvir-containing regimens. Compared with patients with normal kidney function, higher incidences of AKI have been reported in patients with baseline moderate to severe kidney dysfunction. Median time to AKI is 9 weeks after starting sofosbuvir. Baseline renal impairment, presence of ascites, diabetes or concomitant use of nephrotoxic drugs are possible risk factors for sofosbuvir-induced AKI. AKI following sofosbuvir-containing treatment is characterized by histological feature of acute interstitial nephritis and may be reversible following drug discontinuation. Monitoring of kidney function is recommended in sofosbuvir-treated patients. 相似文献
Areas covered: We searched for investigational drugs agents that target different pathophysiological pathways using the key words ‘FSGS’ and ‘podocyte’ in American and European clinical trial registers (clinicaltrials.gov; clinicaltrialsregister.eu). Published articles were searched in PubMed, Medline, the Web of Science and the Cochrane Central Register of Controlled Trials Library.
Expert opinion: Progress is being made in defining the mechanism of action of subtypes of FSGS. Current and investigational therapies for FSGS target these different pathways of injury. It is anticipated that advances in systems biology will further refine the classification of FSGS by subdividing the disease based on the primary mechanism of glomerular injury, identify biomarkers to discriminate between different subtypes, and enable appropriate selection of appropriate therapy for each individual in accordance with the goals of precision medicine. 相似文献
Areas covered: This review discusses the pharmacotherapeutic options for IBS-D including currently used medications, the two newly FDA approved medications, as well as emerging therapies with potential benefit in IBS-D. Particular emphasis is placed on rifaximin and eluxadoline and their possible use in IBS-D.
Expert Opinion: Current pharmacological treatment of IBS-D includes loperamide, bile acid sequestrants, antispasmodics, tricyclic antidepressants, alosetron, eluxadoline and rifaximin. The latter two treatments have significantly added to the pharmacotherapeutic options for patients suffering from IBS-D. 相似文献
Areas covered: In recent years, HCV treatment has changed rapidly and significantly. All-oral treatment regimens show promise for treatment with shorter duration and more manageable side effects. New antivirals aimed at improving SVR may provide a cure to nearly all HCV-infected patients. The unique combination of ABT-450 (paritaprevir) and ABT-267 (ombitasvir) provides highly effective treatment for patients with genotype 1 HCV. This review will examine the antiviral properties, pharmacokinetics, pharmacodynamics, and side effects of these agents.
Expert opinion: The combination of ABT-450/r and ABT-267 has improved potency, favorable side effect profile, and low risk of resistance compared to the first-generation protease inhibitors. This combination is likely to be a major part of novel upcoming HCV treatment regimens and is likely to be widely used by clinicians. Additional data is awaited in additional patient populations, and with possible shorter treatment durations. 相似文献
Areas covered: This article reviews the pharmacokinetic and pharmacodynamic properties of the SOF/LDV fixed dose combination for the treatment of HCV. The topics covered include data regarding the drug´s absorption, distribution, metabolism and excretion and antiviral activity strategies such as the clinical dose selection and treatment duration.
Expert opinion: The SOF/LDV fixed dose combination has good pharmacological properties that lead to a high sustained virological response after 12 or 24 weeks of treatment; there is minimal interference with other drugs or associated renal or hepatic impairment, such that dose adjustment is not necessary. 相似文献
Areas covered: Paritaprevir–ritonavir–ombitasvir and dasabuvir (PrOD), with or without ribavirin, is an all-oral regimen approved for the treatment of HCV genotype 1 infections, including patients with compensated cirrhosis. Phase 2 and 3 clinical trials demonstrated the safety and efficacy of this regimen in HCV genotype 1-infected patients who are treatment-naïve and those who have failed peginterferon/ribavirin therapy. Additional studies evaluated the use of PrOD with or without ribavirin among special populations, including patients co-infected with human immunodeficiency virus-1 and HCV, liver transplant recipients with HCV recurrence, and patients with severe renal impairment. Additionally, the combination of paritaprevir-ritonavir-ombitasvir plus ribavirin is found to be highly efficacious, and is now approved in the US, for the treatment of HCV genotype 4 infections.
Expert opinion: The availability and use of interferon-free DAA combination regimens has resulted in a major paradigm shift in the treatment of HCV. PrOD, with or without ribavirin, is an effective, safe and tolerable treatment option. 相似文献
Areas covered: This review discusses current therapeutic approaches in preclinical and clinical stages, aimed at controlling or preventing hRSV infection. These methods include passive immunization, experimental drugs, vaccine candidates and maternal immunization.
Expert opinion: Based on the results of various immunization strategies and therapeutic approaches, it is likely that the most effective strategy against hRSV will be a prophylactic tool aimed at developing a strong antiviral T-cell response capable of both, promoting the generation of hRSV-specific high affinity antibodies and leading the protective immunity required to prevent the disease caused by this virus. Alternatively, if prophylactic strategies fail, antiviral drugs and novel passive immunity strategies could significantly contribute to reducing hospitalization rates in susceptible individuals. 相似文献
Areas covered: Since platinum free interval (PFI) represents the most important predictive factor for response to platinum re-treatment in ROC, non-platinum regimens are conventionally considered the most appropriate approaches.
Impressive progress has been made in recent decades, resulting in the identification of most effective cytotoxic agents and in the development of new target strategies.
However, the efficacy of most of these drugs for the treatment of PR disease is still limited.
Expert opinion: The most favorable benefit for the treatment of PR disease, has been described by the AURELIA trial that showed a 3.3 months increase in progression free survival (PFS) when bevacizumab was combined with non-platinum single agent chemotherapy in bevacizumab-naïve patients.
Nevertheless, the use of novel agents is associated to important costs for just little gains in survival.
Thus, in our opinion the economic evaluation, such as the incorporation of quality of life into the clinical studies is crucial for the development of future trials for PR-ROC. 相似文献
