Article Abstract
Objective: To evaluate long-term cost-effectiveness of nucleoside analogues and peg-interferon alfa-2a (peg-IFNa2a) for the treatment of chronic hepatitis B (CHB) in hepatitis B e antigen (HBeAg)-negative patients.
Methods: A multi-health slate Markov model was developed based on the disease progression pattern to estimate the long-term effect and medical expense of different treatments for HBeAg-negative CHB.Incremental cost-effectiveness analysis was then carried out.
Results: In comparison with no antiretroviral treatment, all of the antiretroviral treatments were capable of prolonging CHB patients' life years.In particular, entecavir plus adefovir dipivoxil combination therapy showed the best 2 year survival, with expected life-years and quality-adjusted life-years (QALYs) being 19.59 years and 10.12 years, respectively, which were 1.46 years and 1.12 years better than with no antiretroviral treatment. The most cost-effective treatment for HBeAg-negative CHB was lamivudine plus adefovir dipivoxil rescue therapy, as it prolonged survival by 0.95 QALYs with an additional 15459 yuan; the incremental medical cost for gaining 1 QALY was 16273 yuan.
Conclusion: Among the antiretroviral medicines applied as therapy for HBeAg-negative CHB in China, the most effective treatment is entecavir plus adefovir dipivoxil rescue therapy and the most cost-effective treatment is lamivudine plus adefovir dipivoxil rescue therapy.

Article Synopsis
- Hypophosphatemic osteomalacia is a rare condition marked by low phosphate levels, which can occur due to genetic or acquired factors, and a case study discusses its management and prognosis when caused by specific antiviral drugs.
- A 55-year-old man with chronic hepatitis B experienced symptoms like chest pain and fatigue after switching from adefovir to tenofovir, leading to the diagnosis of drug-induced hypophosphatemic osteomalacia.
- Treatment included stopping the problematic drugs, switching to entecavir, and recommending dietary changes and supplements, which resulted in improved phosphate levels and resolution of symptoms.

Article Synopsis
- Adefovir was studied to understand how it interacts with renal transporters when combined with other drugs, showing a 20% increase in systemic exposure when used together with metformin, sitagliptin, pitavastatin, and digoxin.
- A population pharmacokinetic (popPK) model was used to analyze data from 24 healthy subjects, revealing that adefovir's absorption and bioavailability were significantly higher during combination therapy compared to when it was administered alone.
- The findings indicate that while co-administering drugs mainly influenced adefovir's absorption and conversion, its renal elimination process remained unchanged, suggesting limited drug-drug interactions in this context.

To study the curative effect of rehmannia glutinosa leaves total glycoside capsules and the role of mitochondrial autophagy on nucleos(t)ide drug-induced renal injury. Adefovir dipivoxil (ADV) was used to construct a hepatitis B virus (HBV) transgenic mouse model for renal injury. Renal function was measured in each group at one and two weeks of modeling.

This study presents the case of a 53-year-old man who had been taking ADV 10 mg daily for 10 years to treat chronic hepatitis B (CHB) and subsequently developed Fanconi syndrome. The clinical manifestations included hypophosphatemic osteomalacia, glucosuria, renal tubular acidosis, low-molecular-weight proteinuria, and renal insufficiency.
