Published: April 1999

Trovafloxacin, a new fluoroquinolone, produced bactericidal activity (-0.33 +/- 0.13 delta log10 CFU/ml.h; intravenously [i.v.] administered dose, 15 mg/kg) comparable to that of vancomycin (-0.39 +/- 0.18 delta log10 CFU/ml.h; i.v. admininistered dose, 20 mg/kg) in the treatment of experimental meningitis in rabbits due to a pneumococcal strain highly resistant to penicillin (MIC of penicillin G, 4 micrograms/ml). The combination of both drugs significantly increased (P < 0.05) the killing rate (-0.60 +/- 0.23 delta log10 CFU/ml.h) compared to that produced by either monotherapy. These results were also confirmed in vitro.

Background And Aim: Bulevirtide (BLV) leads to beneficial virologic and biochemical responses when given alone to treat hepatitis delta virus (HDV) infection, which causes the most severe form of chronic viral hepatitis. We evaluated 48 weeks of BLV monotherapy, BLV + tenofovir disoproxil fumarate (TDF) and BLV + pegylated interferon alfa-2a (Peg-IFNα-2a), with 24-week follow-up.

Methods: Ninety patients were enrolled into six arms of 15 each (A-F); 60 patients were included in the main randomisation (arms A-D), and 30 patients (arms E-F) were randomised to the extension phase: (A) Peg-IFNα-2a 180 μg once weekly (QW); (B) BLV 2 mg once daily (QD) + Peg-IFNα-2a 180 μg QW; (C) BLV 5 mg QD + Peg-IFNα-2a 180 μg QW; (D) BLV 2 mg QD; (E) BLV 10 mg QD + Peg-IFNα-2a 180 μg QW and (F) BLV 10 mg (5 mg twice daily) + TDF QD.

Background And Aims: Bulevirtide (BLV) 2 mg/day is EMA approved for treatment of compensated chronic hepatitis due to Delta virus (HDV) infection, however real-life data in large cohorts of patients with cirrhosis are lacking.

Methods: Consecutive HDV-infected patients with cirrhosis starting BLV 2 mg/day since September 2019 were included in a European retrospective multicenter real-life study (SAVE-D). Patient characteristics before and during BLV treatment were collected.

Electronic address:

Background & Aims: Serum HBV RNA and hepatitis B core-related antigen (HBcrAg) levels have been proposed as useful biomarkers in the management of patients with HBV; however, their role in chronic hepatitis delta (CHD) is currently unknown.

Methods: Consecutive untreated patients with CHD were enrolled in a cross-sectional study in three EU centers. Clinical and virological characteristics were collected.

Article Synopsis
  • Immunosuppressive medication dosing after organ transplantation typically relies on therapeutic drug monitoring, but this method may not effectively predict rejection or infections.
  • The TTVguideIT trial investigates using Torque Teno Virus (TTV) load measurement via qPCR as a potentially better alternative for dosing tacrolimus.
  • Results demonstrated that the TTV R-GENE® assay showed excellent accuracy and consistency across participating labs, allowing for standardized TTV load measurement in clinical trials.

Article Synopsis
  • The study investigates the link between Torque Teno virus (TTV) load and the immune system's functionality, proposing TTV as a potential monitoring tool for immune-modulating therapy.
  • There is a noted correlation between decreased complement activity due to the anti-C1s antibody sutimlimab and an increase in TTV load among both healthy volunteers and kidney transplant recipients.
  • The findings suggest that the classical complement pathway may play a significant role in regulating TTV load, with varying trends based on the dosing of sutimlimab.
