Tenofovir Disoproxil Fumarate Reduces the Severity of COVID-19 in Patients with Chronic Hepatitis B.

ABSTRACT:

Background and aims

HIV-positive patients on tenofovir hydroxyl fumarate (TDF)/emtricitabine have a lower risk of COVID-19 and hospitalization than those given other treatments. Our aim was to analyze the severity of COVID-19 in patients with chronic hepatitis B (CHB) on TDF or entecavir (ETV).

Methods

Spanish hospital databases (n = 28) including information regarding adult CHB patients on TDF or ETV for the period February 1st to November 30th 2020 were searched for COVID-19, defined as a positive SARS-CoV-2 polymerase chain reaction, and for severe COVID-19.

Results

Of 4736 patients, 117 had COVID-19 (2.5%), 67 on TDF and 50 on ETV. Compared to patients on TDF, those on ETV showed (p < 0.05) greater rates of obesity, diabetes, ischemic cardiopathy, and hypertension. COVID-19 incidence was similar in both groups (2.3 vs. 2.6%). Compared to TDF, patients on ETV more often (p < 0.01) had severe COVID-19 (36 vs. 6%), required intensive care unit (ICU) (10% vs. 0) or ventilatory support (20 vs. 3%), were hospitalized for longer (10.8 ± 19 vs. 3.1 ± 7 days) or died (10 vs. 1.5%, p = 0.08). In an IPTW propensity score analysis adjusted for age, sex, obesity, comorbidities, and fibrosis stage, TDF was associated with a sixfold reduction in severe COVID-19 risk (adjusted-IPTW-OR 0.17, 95%CI 0.04-0.67, p = 0.01).

Conclusion

Compared to ETV, TDF seems to play a protective role in CHB patients with SARS-CoV-2 whereby the risk of severe COVID-19 is lowered.

Project description:Background & aimsAntiviral therapy may attenuate the risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). We aimed to explore how tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) affect HCC risk in patients with CHB.MethodsThe REACH-B, aMAP, and mPAGE-B models were utilized to assess HCC risk in patients with CHB from two global randomized-controlled trials evaluating the impact of TAF vs. TDF treatment. Standard incidence ratios (SIRs) were calculated using data from the REACH-B model as a ratio of observed HCC cases in the TAF- or TDF-treated patients vs. predicted HCC cases for untreated historical controls. Proportions of treated patients shifting aMAP and mPAGE-B risk categories between baseline and Week 240 were calculated.ResultsOf the 1,632 patients (TAF, n = 1,093; TDF, n = 539) followed for up to 300 weeks, 22 HCC cases developed. Those receiving TAF had an SIR that was lower compared to the SIR of individuals receiving TDF: 0.32 (p <0.001) vs. 0.56 (p = 0.06). In the general study population, individuals without cirrhosis at baseline had an SIR that was lower compared to the SIR of individuals with cirrhosis at baseline: 0.37 (p <0.001) vs. 0.58 (p = 0.15). Of the patients at low risk of HCC at baseline, the majority (97%) remained low risk by mPAGE-B and aMAP scoring at Week 240. Among those at medium or high risk at baseline, substantial portions shifted to a lower risk category by Week 240 (mPAGE-B: 22% and 42%; aMAP: 39% and 63%, respectively).ConclusionsThis evaluation provides evidence that treatment with TAF or TDF can reduce HCC risk in patients with CHB, particularly in patients without cirrhosis.Impact and implicationsDespite the substantial impact of HCC on long-term outcomes of patients with CHB, the differential risk of HCC development among those receiving treatment with TAF vs. TDF has not been well elucidated. Using three validated risk prediction models, we found that TAF is at least as effective as TDF in reducing HCC risk in patients with CHB. While TDF is well-studied in the context of HCC risk reduction, our novel findings underscore the effectiveness of TAF as a treatment option for patients with CHB.Clinical trial numbersNCT01940341; NCT02836249; NCT01940471; NCT02836236.

Project description:This study aimed to compare the serum lipid profiles between tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) in the long-term treatment of chronic hepatitis B (CHB). We analyzed data from treatment-naïve CHB patients administered with TDF or TAF, collected from electronic medical records between May 2017 and September 2022. Serum lipid indices, including total cholesterol (TC), triglycerides (TG), low-density (LDL) and high-density lipoprotein (HDL), and their ratios (TC/HDL, LDL/HDL), were assessed at baseline, and at 48 and 96 weeks. Propensity score matching (PSM) adjusted for baseline differences between groups. From 2344 patients initially screened, 418 were included for the 48-week analysis (265 on TDF, 153 on TAF) and 292 for the 96-week analysis (238 on TDF, 54 on TAF). At 48 weeks, comparing the serum lipid indicators between the pre- and post-treatment, TDF significantly reduced TC and TC/HDL, whereas TAF induced widespread dyslipidemia, characterized by elevated levels of TC, TG, LDL, LDL/HDL, and TC/HDL, and reduced HDL (P < 0.05). After PSM grouping, TAF remained significantly associated with higher TC, TG, LDL, LDL/HDL, and TC/HDL compared to TDF (P < 0.05). Over 48 weeks, TAF treatment was associated with significant increases in TC, TG, and LDL, whereas TDF treatment led to decreases (P < 0.05). TC/HDL and LDL/HDL increased in both groups, but more significant in TAF (P < 0.05). At 96 weeks, the TAF group continued to exhibit significantly higher levels of TC, LDL, and LDL/HDL compared to the TDF group (P < 0.05). Notably, LDL levels were 115.65 ± 28.07 mg/dL in TAF versus 96.07 ± 23.97 mg/dL in TDF. The increase in TC/HDL ratio in the TAF group was higher than in the TDF group, though not statistically significant. Furthermore, TAF treatment was associated with significant increases in LDL (18.58 ± 24.35 mg/dL) and LDL/HDL ratio (0.41 ± 0.95) over 96 weeks, while TDF treatment showed reductions in TC (-8.13 ± 30.86 mg/dL). Between 48 and 96 weeks, most lipid changes in the TDF group were not statistically significant, except for increases in LDL and LDL/HDL. In the TAF group, an increasing trend of LDL and TC/HDL was noted, although LDL showed a slight turnover after 48 weeks. This real-world study provides new evidence that TAF can induce dyslipidemia, while TDF exhibits a lipid-lowering effect in CHB. Patients at high risk for hepatic steatosis and cardiovascular diseases should consider these effects when choosing between TAF and TDF.
