Salama II, Raslan HM, Abdel-Latif GA, Salama SI, Sami SM, Shaaban FA, Abdelmohsen AM, Fouad WA. Impact of direct-acting antiviral regimens on hepatic and extrahepatic manifestations of hepatitis C virus infection. World J Hepatol 2022; 14:1053-1073. [PMID: 35978668 PMCID: PMC9258264 DOI: 10.4254/wjh.v14.i6.1053] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 04/01/2022] [Accepted: 05/23/2022] [Indexed: 02/06/2023] Open
Abstract
Hepatitis C virus (HCV) is a common cause of liver disease and is associated with various extrahepatic manifestations (EHMs). This mini-review outlines the currently available treatments for HCV infection and their prognostic effect on hepatic manifestations and EHMs. Direct-acting antiviral (DAA) regimens are considered pan-genotypic as they achieve a sustained virological response (SVR) > 85% after 12 wk through all the major HCV genotypes, with high percentages of SVR even in advanced fibrosis and cirrhosis. The risk factors for DAA failure include old males, cirrhosis, and the presence of resistance-associated substitutions (RAS) in the region targeted by the received DAAs. The effectiveness of DAA regimens is reduced in HCV genotype 3 with baseline RAS like A30K, Y93H, and P53del. Moreover, the European Association for the Study of the Liver recommended the identification of baseline RAS for HCV genotype 1a. The higher rate of hepatocellular carcinoma (HCC) after DAA therapy may be related to the fact that DAA regimens are offered to patients with advanced liver fibrosis and cirrhosis, where interferon was contraindicated to those patients. The change in the growth of pre-existing subclinical, undetectable HCC upon DAA treatment might be also a cause. Furthermore, after DAA therapy, the T cell-dependent immune response is much weaker upon HCV clearance, and the down-regulation of TNF-α or the elevated neutrophil to lymphocyte ratio might increase the risk of HCC. DAAs can result in reactivation of hepatitis B virus (HBV) in HCV co-infected patients. DAAs are effective in treating HCV-associated mixed cryoglobulinemia, with clinical and immunological responses, and have rapid and high effectiveness in thrombocytopenia. DAAs improve insulin resistance in 90% of patients, increase glomerular filtration rate, and decrease proteinuria, hematuria and articular manifestations. HCV clearance by DAAs allows a significant improvement in atherosclerosis and metabolic and immunological conditions, with a reduction of major cardiovascular events. They also improve physical function, fatigue, cognitive impairment, and quality of life. Early therapeutic approach with DAAs is recommended as it cure many of the EHMs that are still in a reversible stage and can prevent others that can develop due to delayed treatment.

Abstract
Diagnosis of renal transplant rejection is dependent on interpretation of renal allograft biopsies. The Banff Classification of Allograft Pathology, which was developed as a standardized working classification system in 1991, has contributed to the standardization of definitions for histologic injuries resulting from renal allograft rejections and provided a universal grading system for assessing these injuries. It has also helped to provide insight into the underlying pathogenic mechanisms that contribute to transplant rejection. In addition to histological and immunologic parameters, molecular tools are now being used to facilitate the diagnosis of rejection. In this review, I will discuss morphologic features of renal transplant rejections as well as major revisions and pitfalls of the Banff classification system, and provide future perspectives.

Transpl Infect Dis 2018; 21:e13018. [PMID: 30369001 DOI: 10.1111/tid.13018] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 09/17/2018] [Accepted: 10/01/2018] [Indexed: 12/24/2022]
Abstract
OBJECTIVES To assess the efficacy and the risk of sofosbuvir-daclatasvir treatment among kidney transplant recipients (KTRs) with chronic hepatitis C virus (HCV) infection. METHODS A real-life retrospective cohort analysis was performed on KTRs treated with sofosbuvir-daclatasvir at our center between January 2016 and March 2018. We collected data from 19 KTRs (13 males; age 48.3 ± 9.6 years; HCV genotype I, n = 16; chronic active hepatitis B coinfection, n = 8). Virological and clinical data were assessed. RESULTS Overall, 100% of the patients had achieved a sustained virological response 12 weeks after treatment (SVR12). Their liver function improved notably, with a significant decline in the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels (ALT 34.8 ± 18.6 IU/L pre-treatment and 15.0 ± 6.8 IU/L post-treatment, P = 0.0003; AST: 35.05 ± 18.1 IU/L pre-treatment and 19.1 ± 7.0 post-treatment, P = 0.001). A significant amelioration was observed in patients with proteinuria (n = 12) (0.95 [0.35-3.31] g/g at baseline to 0.39 [0.27-1.02] g/g post-therapy, P = 0.048). The serum creatinine, eGFR, and tacrolimus levels were stable during therapy. CONCLUSION The preliminary data demonstrated that sofosbuvir-daclatasvir was highly effective in treating HCV infection in KTRs with acceptable tolerance.

Abstract
We herein report a unique case of hepatitis C virus (HCV)-associated renal disease without cryoglobulinemia that showed proteinuria, hypoproteinemia, ascites, and edema. Due to combination therapy with daclatasvir and asunaprevir, the patient achieved sustained virological response at week 24 of the therapy. Furthermore, the therapy caused marked amelioration of her proteinuria, ascites, edema, and hypoalbuminemia, and finally improved her estimated glomerular filtration rate. There were no adverse events, and the combination therapy was well-tolerated. We recommend that HCV eradication with antiviral therapy using direct-acting antiviral agents be attempted first for all renal disease with HCV infection, regardless of cryoglobulinemia, considering the existence of resistance-associated variants.

Rituximab for Treatment of Membranoproliferative Glomerulonephritis and C3 Glomerulopathies. BIOMED RESEARCH INTERNATIONAL 2017; 2017:2180508. [PMID: 28573137 PMCID: PMC5440792 DOI: 10.1155/2017/2180508] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Accepted: 04/20/2017] [Indexed: 01/18/2023]
Abstract
Membranoproliferative glomerulonephritis (MPGN) is a histological pattern of injury resulting from predominantly subendothelial and mesangial deposition of immunoglobulins or complement factors with subsequent inflammation and proliferation particularly of the glomerular basement membrane. Recent classification of MPGN is based on pathogenesis dividing MPGN into immunoglobulin-associated MPGN and complement-mediated C3 glomerulonephritis (C3GN) and dense deposit disease (DDD). Current guidelines suggest treatment with steroids, cytotoxic agents with or without plasmapheresis only for subjects with progressive disease, that is, nephrotic range proteinuria and decline of renal function. Rituximab, a chimeric B-cell depleting anti-CD20 antibody, has emerged in the last decade as a treatment option for patients with primary glomerular diseases such as minimal change disease, focal-segmental glomerulosclerosis, or idiopathic membranous nephropathy. However, data on the use of rituximab in MPGN, C3GN, and DDD are limited to case reports and retrospective case series. Patients with immunoglobulin-associated and idiopathic MPGN who were treated with rituximab showed partial and complete responses in the majorities of cases. However, rituximab was not effective in few cases of C3GN and DDD. Despite promising results in immunoglobulin-associated and idiopathic MPGN, current evidence on this treatment remains weak, and controlled and prospective data are urgently needed.
