Aims: TASL HCV Registry (TACR) is a nationwide registry program organized and supervised by Taiwan Association for the Study of the Liver (TASL), which aims to setup the database and biobank of patients with chronic hepatitis C (CHC) in Taiwan. The present study aimed to evaluate the treatment outcome of sofosbuvir (SOF)/ledipasvir (LDV) in Taiwanese CHC patients in TACR. Methods: By May 2020, 19 tertiary hospitals, 23 community hospitals and one primary care clinic join the TACR program. The baseline characteristics, prior liver and non-liver related medical history, DAA regimens, laboratory results, treatment course and outcome were recorded. The primary objective was sustained virological response, defined as undetectable HCV RNA 3 months after end-of-treatment (SVR12). Results: A total of 4742 SOF/LDV+ ribavirin treated CHC patients with available SVR12 data from 39 sites were enrolled in the current analysis. The mean age was 61.3 years, and female accounted for 54.8% of the population. The dominant viral genotypes were GT1b (52.6%) and GT2 (35.6%). 1354 (28.6%) patients had liver cirrhosis, including 156 (3.3%) with liver decompensation, 552 (11.6%) had preexisting hepatocellular carcinoma (HCC) before DAAs treatment and 413 (8.7%) had hepatitis B virus dual infections. The overall SVR12 rate was 98.5%, with 98.5%, 98.2%, 99.7% and 98.6% in treatment- naïve non-cirrhotics, treatment-naïve cirrhotics, treatment- experienced non-cirrhotics and treatment-experienced cirrhotics patients, respectively. While patients were stratified by HCV genotype, the SVR12 was 98.5%, 98.4% and 98.5% among those with GT1, GT2 and GT6 infection, respectively. The strongest factor independent associated with treatment failure was DAA adherence < 60% (odds ratio [OR]/95% confidence intervals [CI]: 125.4/25.7-612.4, P<0.0001), followed by active HCC (OR/CI: 6.20/2.57-14.97, P<0.0001), HIV co-infection (OR/CI: 3.01/1.14-7.92, P=0.026), and male gender (OR/ CI: 1.85/1.09-3.13, P=0.023). The eGFR decreased significantly at the end of treatment (EOT) (89.3 ml/min/1.73㎡ vs. 93.2 ml/min/1.73㎡, P< 0.001) and remained stable 3 months after EOT (89.3 ml/min/1.73㎡). However, the decreased eGFR was observed only in patients whose baseline eGFR > 90 ml/ min/1.73㎡. Instead, patients with chronic kidney diseases whose pretreatment eGFR < 60 ml/min/1.73㎡ had improved eGFR after SOF/LDV. Conclusions: SOF/LDV is highly effective in treating CHC patients in real-world setting of Taiwan. The satisfactory result could be explicitly generalized to patients with different viral genotypes and liver disease severities.

Neutron and X-ray scattering on the monolayer structure of a lecithin fullerene-derivative.

<P>Using neutron reflectivity with contrast variation, X-ray reflectivity, and grazing incident small-angle X-ray scattering (GISAXS), we have characterized the in-depth and in-plane structural characteristics of the Langmuir and Langmuir-Blodgett (LB) films formed by a novel lecithin C60-derivative, FPTL, of three phospholipids jointly bonded on one single olefinic moiety of a C60 cage. Based on the neutron reflectivity measured, we have proposed a monolayer structure, with the C60 cages of FPTL lifted into the air and hydrophilic phospholipid heads immersed in water, for the FPTL Langmuir layer formed on water. On the other hand, the LB film of FPTL prepared on mica exhibits clear Kiessig fringes in the X-ray reflectivity profile, indicating a 27 angstroms monolayer film with less molecular orientation. With GISAXS, we have extracted an in-plane correlation length of about 210 A for a possible in-plane aggregation of C60 of FPTL in the LB monolayer. We have also demonstrated the highly ordered monolayer structures of a lecithin lipid, in elucidating the positive effect of the attached functional group-phospholipids on the monolayer formation of the lecithin C60-derivative.</P>
