We report the case of a 7-year-old unimmunized boy who presented with generalized anasarca for the first time, along with nephrotic-range proteinuria, hypoalbuminemia, microscopic hematuria and hypertension. Special investigations revealed ELISA test to be positive for hepatitis B surface antigen (HBsAg) and hepatitis B envelope antigen (HBeAg); hepatitis B viral DNA load (HBV DNA) level (real-time polymerase chain reaction) was 54 360 903 IU/ml. For hepatitis B virus (HBV)-related glomerulopathy, he was started on enalapril and lasilactone, and percutaneous renal biopsy was performed, which revealed membranous nephropathy (MN)...

Interferon-alpha (IFN-alpha) is recommended in neuroendocrine tumors (NET). Malignant pheochromocytoma and paragangliomas (MPPGLs) constitute a rare subgroup of NET with few treatment options. IFN-alpha efficacy in patients with MPPGLs was evaluated in a single-center retrospective study. Progression-free survival (PFS) was the primary endpoint according to RECIST 1.1 and/or PERCIST 1.0, and response rate, safety, and symptomatic efficacy were secondary endpoints. Fourteen patients received peginterferon alfa-2a (90 to 180 μg/week) or interferon alfa-2b (1...

The phase 2b EMERGE study compared the efficacy/safety of peginterferon lambda-1a (Lambda) and peginterferon alfa-2a (Alfa), both with ribavirin (RBV), for treatment of chronic hepatitis C virus (HCV) infection. A key safety finding was a higher frequency of hyperbilirubinemia with Lambda/RBV versus Alfa/RBV. To characterize mechanisms of hyperbilirubinemia associated with Lambda/RBV, we conducted a retrospective analysis of safety data from the HCV genotype 1 and genotype 4 cohort of the EMERGE study. Subjects were randomized to once-weekly Lambda (120/180/240 μg) or Alfa (180 μg), with daily RBV, for 48 weeks...

BACKGROUND & AIMS: Peginterferon lambda-1a (lambda) is a Type-III interferon, which, like alfa interferons, has antiviral activity in vitro against hepatitis B virus (HBV) and hepatitis C virus (HCV); however, lambda has a more limited extra-hepatic receptor distribution. This phase 2b study (LIRA-B) evaluated lambda in patients with chronic HBV infection. METHODS: Adult HBeAg+ interferon-naive patients were randomized (1:1) to weekly lambda (180 μg) or peginterferon alfa-2a (alfa) for 48 weeks...

Peginterferon alfa (alfa) increases the risk of autoimmune disease. Peginterferon lambda-1a (Lambda) acts through a receptor with a more liver-specific distribution compared to the alfa receptor. In a phase-2b study, 525 treatment-naive patients with chronic hepatitis C virus (HCV) infection received ribavirin and Lambda interferon (120, 180, or 240 μg) or alfa interferon (180 μg) for 24 (genotypes 2 and 3) or 48 (genotypes 1 and 4) weeks. Retrospective analysis found that adverse events of MedDRA-coded thyroid dysfunction and abnormal levels of thyroid-stimulating hormone (TSH) were significantly more frequent with alfa versus Lambda (12% versus 2...

PURPOSE: The pharmacology, pharmacokinetics, efficacy, safety, costs, and place in therapy of simeprevir and sofosbuvir in the management of hepatitis C virus (HCV) infection are reviewed. SUMMARY: Sofosbuvir and simeprevir are classified as direct-acting agents because they target specific proteins essential to the replication of HCV. Phase III trials demonstrated that simeprevir in combination with peginterferon alfa and ribavirin was superior to placebo combined with peginterferon alfa and ribavirin in achieving a sustained virological response in both treatment-naive patients and patients who relapsed after treatment with peginterferon alfa-2a or alfa-2b and ribavirin...

Chronic HCV is one of the commonest causes of chronic liver disease worldwide with about 15% of population infected in Egypt. Certain single nucleotide polymorphisms (SNPs) lying near the IL28B gene were found to affect the spontaneous clearance as well as treatment outcome of HCV. To examine the association between different IL28B variants and the relapse of HCV infection after combined therapy with ribavirin and pegylated interferon (pegIFN). Hundered HCV genotype four patients received 1.5 mg/kg/week peginterferon alfa-2b plus 800-1400 mg/d ribavirin (weight-adjusted) for 48 weeks...

Dual hepatitis C virus (HCV) and hepatitis B virus (HBV) infection is not rare in HBV or HCV endemic areas, and can be found in populations at risk of parenteral viral transmission. Clinical observatory studies suggest a higher risk of liver disease progression in patients with dual HCV/HBV infection than in HBV or HCV monoinfected patients. Recent trials confirmed that combination therapy of peginterferon alfa-2a or alfa-2b and ribavirin was effective and safe in dually infected patients with positive HCV RNA...

Chronic hepatitis B (CHB) continues to be an important public health problem worldwide, including in the United States. An algorithm for managing CHB was developed by a panel of United States hepatologists in 2004 and subsequently updated in 2006 and 2008. Since 2008, additional data on long-term safety and efficacy of licensed therapies have become available and have better defined therapeutic options for CHB. The evidence indicates that potent antiviral therapy can lead to regression of extensive fibrosis or even cirrhosis, thus potentially altering the natural history of CHB...

The incidence of malignant melanoma is increasing. The majority of patients are diagnosed in early stages when the disease is highly curable. However, the more advanced or metastatic cases have always been a challenge for clinicians. The poor prognosis for patients with melanoma is now changing as numerous of promising approaches have appeared recently. The discovery of aberrations of pathways responsible for intracellular signal transduction allowed us to introduce agents specifically targeting the mutated cascades...

Peginterferon lambda-1a (Lambda), a type III interferon (IFN), acts through a unique receptor complex with limited cellular expression outside the liver which may result in a differentiated tolerability profile compared to peginterferon alfa (alfa). In Phase 2b clinical studies, Lambda administered in combination with ribavirin (RBV) was efficacious in patients with hepatitis C virus (HCV) infection representing genotypes 1 through 4, and was associated with more rapid declines in HCV RNA compared to alfa plus RBV...

INTRODUCTION: The WHO estimates that 180 million people are chronically infected with hepatitis C virus (HCV) throughout the world. Despite the emergence of new therapies, the combination of pegylated interferon and ribavirin remains the accepted standard of care in low-income countries, including Mexico. Two types of peginterferon are available (peginterferon alfa-2a and peginterferon alfa-2b), and both are recommended for the treatment of HCV, although there is controversy over which treatment option is most effective...
