Second-Line Tisagenlecleucel or Standard Care in Aggressive B-Cell Lymphoma.

Background: Patient outcomes are poor for aggressive B-cell non-Hodgkin's lymphomas not responding to or progressing within 12 months after first-line therapy. Tisagenlecleucel is an anti-CD19 chimeric antigen receptor T-cell therapy approved for diffuse large B-cell lymphoma after at least two treatment lines.

Methods: We conducted an international phase 3 trial involving patients with aggressive lymphoma that was refractory to or progressing within 12 months after first-line therapy.

Neonates Born to Mothers With COVID-19: Data From the Spanish Society of Neonatology Registry.

Objectives: To describe neonatal and maternal characteristics of the largest prospective cohort of newborns from mothers with coronavirus disease 2019 (COVID-19), the data of which were prospectively collected from the nationwide registry of the Spanish Society of Neonatology.

Methods: Between March 8, 2020, and May 26, 2020, the data of 503 neonates born to 497 mothers diagnosed with COVID-19 during pregnancy or at the time of delivery were collected by 79 hospitals throughout Spain.

Results: Maternal symptoms were similar to that of the general population, with 5% of severe forms.

Optimisation of the use of APRI and FIB-4 to rule out cirrhosis in patients with chronic hepatitis B: results from the SONIC-B study.

Background: Ruling out the presence of cirrhosis is important for the management of chronic hepatitis B. We aimed to study and optimise the performance of two non-invasive indices for ruling out cirrhosis: the aspartate aminotransferase-platelet ratio index (APRI) and fibrosis score based on four factors (FIB-4).

Methods: We applied established cutoffs to rule in (APRI >2·00; FIB-4 >3·25) or rule out (APRI <1·00; FIB-4 <1·45) cirrhosis to data from eight global randomised trials that required baseline biopsy, and identified new cutoffs aiming for a sensitivity for detection of cirrhosis greater than 90% and a negative predictive value (NPV) of greater than 95% in the same dataset.

New Dual Combination of Dolutegravir-Rilpivirine for Switching to Maintenance Antiretroviral Therapy.

Advances in antiretroviral therapy have led to dramatic improvements in survival of HIV-infected persons. However, HIV cure remains elusive and lifelong treatment is needed. Attempts for reducing long-term drug exposure, toxicities, and cost, while maintaining viral suppression, have led to explore whether maintenance strategies with less than triple therapy could be feasible using the newest more potent antiretrovirals.

Thrombotic thrombocytopenic purpura relapse induced by acute hepatitis E transmitted by cryosupernatant plasma and successfully controlled with ribavirin.

Background: Hepatitis E virus (HEV) can be transmitted by transfusion of any type of blood component, but there are few data on the potential risk of transmitting this virus and the associated complications. We provide evidence that HEV can be transmitted by cryosupernatant plasma, and that HEV infection can act as a trigger for thrombotic thrombocytopenic purpura (TTP).

Study Design And Methods: A patient with a history of TTP treated with plasmapheresis 2 months previously developed jaundice and a TTP exacerbation with purpura, thrombocytopenia, schistocytes, and undetectable ADAMTS-13 activity.

Hepatitis B virus: The challenge of an ancient virus with multiple faces and a remarkable replication strategy.

The hepatitis B virus (HBV) is the prototype member of the Hepadnaviridae, an ancient family of hepatotropic DNA viruses, which may have originated from 360 to 430 million years ago and with evidence of endogenization in reptilian genomes >200 million years ago. The virus is currently estimated to infect more than 250 million humans. The extremely successful spread of this pathogen among the human population is explained by its multiple particulate forms, effective transmission strategies (particularly perinatal transmission), long induction period and low associated mortality.

Efficacy of Sofosbuvir and Velpatasvir, With and Without Ribavirin, in Patients With Hepatitis C Virus Genotype 3 Infection and Cirrhosis.

Background & Aims: In phase 3 trials and real-world settings, smaller proportions of patients with genotype 3 hepatitis C virus (HCV) infection and cirrhosis have a sustained virologic response 12 weeks after treatment (SVR12) with the combination of sofosbuvir and velpatasvir than in patients without cirrhosis. It is unclear whether adding ribavirin to this treatment regimen increases SVRs in patients with genotype 3 HCV infection and cirrhosis.

Methods: We performed a phase 2 trial of 204 patients with genotype 3 HCV infection and compensated cirrhosis (mean age 51 ± 7.

Long-term safety and efficacy of guanfacine extended release in children and adolescents with ADHD.

Data are reported from SPD503-318, a phase 3, open-label, safety study of guanfacine extended release (GXR) in European children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Participants received dose-optimized GXR (1-7 mg/day) for up to 2 years. Of 215 enrolled participants, 214 were included in the safety population and 133 completed the study.

Long-term safety and efficacy of nucleo(t)side analogue therapy in hepatitis B.

Long-term treatment of chronic hepatitis B (CHB) with nucleos(t)ide analogues is often necessary to achieve durable viral suppression. Therefore, current guidelines recommend the most potent drugs with optimal resistance profiles. Entecavir (ETV), tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) are the first-line monotherapies for CHB.

Kidney allograft subclinical rejection modulates systemic inflammation measured by C-reactive protein at 1 year after transplantation.

Kidney allograft inflammation is associated with proinflammatory modifications of peripheral blood mononuclear cells, suggesting that renal inflammation contributes to systemic inflammation. Thus, the aim of this study was to evaluate the relationship between subclinical inflammation in surveillance biopsies performed at 1 year and systemic inflammation assessed by C-reactive protein (CRP) levels at the time of biopsy. We analyzed 544 surveillance biopsies performed at 1 year that were classified as normal (n = 368), borderline (n = 148), or subclinical rejection (SCR) (n = 28).

Hepatitis C in Patients With Minimal or No Hepatic Fibrosis: The Impact of Treatment and Sustained Virologic Response on Patient-Reported Outcomes.

Background: While the necessity of treatment of hepatitis C virus (HCV)-infected patients with advanced liver disease is widely accepted, the benefit of treating patients without significant liver disease is less well established. Our aim was to assess the effect of treating HCV in patients with no or minimal fibrosis (Metavir stage F0-F1) on patient-reported outcomes (PROs).

Methods: HCV-infected patients with F0-F1 from 16 clinical trials were included.

Tenofovir Alafenamide Fumarate: A New Tenofovir Prodrug for the Treatment of Chronic Hepatitis B Infection.

Tenofovir alafenamide fumarate (TAF), a new prodrug of tenofovir and a potential successor of tenofovir disoproxil fumarate (TDF), has been approved in the United States and Europe for treating adolescents and adults with chronic hepatitis B infection. TAF is formulated to deliver the active metabolite to target cells more efficiently than TDF at lower doses, thereby reducing systemic exposure to tenofovir. In patients with chronic hepatitis B, TAF appears to be as effective as TDF, with lower bone and renal toxicity.

Downregulation of mucosal mast cell activation and immune response in diarrhoea-irritable bowel syndrome by oral disodium cromoglycate: A pilot study.

Background And Goal: Diarrhoea-predominant irritable bowel syndrome (IBS-D) exhibits intestinal innate immune and mucosal mast cell (MC) activation. MC stabilisers have been shown to improve IBS symptoms but the mechanism is unclear. Our primary aim was to investigate the effect of oral disodium cromoglycate (DSCG) on jejunal MC activation and specific innate immune signalling pathways in IBS-D, and secondarily, its potential clinical benefit.

Serum hepatitis B core-related antigen is more accurate than hepatitis B surface antigen to identify inactive carriers, regardless of hepatitis B virus genotype.

Objectives: To investigate whether hepatitis B surface antigen (HBsAg) and hepatitis B core-related antigen (HBcrAg) levels are useful to identify inactive carriers among HBeAg-negative patients infected by different hepatitis B virus (HBV) genotypes.

Methods: In all, 202 consecutive HBeAg-negative patients with chronic hepatitis B, 135 inactive carriers and 67 with HBV activity, were prospectively followed for 1 year.

Results: In HBeAg-negative patients, HBsAg levels differed across the different genotypes (p <0.

Management of direct antiviral agent failures.

The current standard of care for patients with chronic hepatitis C virus (HCV) infection is a combination of direct-acting antiviral agents (DAAs). Most HCV patients treated with these drugs achieve viral elimination, but 1% to 15% fail to attain this objective. Treatment failures are usually related to relapse, and less often to on-treatment viral breakthrough.

Effectiveness and Safety of Entecavir or Tenofovir in a Spanish Cohort of Chronic Hepatitis B Patients: Validation of the Page-B Score to Predict Hepatocellular Carcinoma.

Background: Long-term antiviral therapy has resulted in viral suppression and biochemical response in chronic hepatitis B, although the risk of hepatocellular carcinoma has not been abolished. The Page-B score could be useful to estimate the probability of HCC.

Aims: To analyze the effectiveness and safety of entecavir or tenofovir for more than 4 years and the usefulness of Page-B score in the real-world setting.

Red blood cell transfusion-transmitted acute hepatitis E in an immunocompetent subject in Europe: a case report.

Background: Acute hepatitis E in industrialized countries is usually related to intake or manipulation of undercooked or raw meat. Cases of transfusion-transmitted hepatitis E have rarely been documented in immunosuppressed patients, mainly after receiving frozen plasma.

Study Design And Methods: A 61-year-old man was admitted to hospital for jaundice.

Inflammation in Early Kidney Allograft Surveillance Biopsies With and Without Associated Tubulointerstitial Chronic Damage as a Predictor of Fibrosis Progression and Development of De Novo Donor Specific Antibodies.

Background: Interstitial fibrosis and tubular atrophy (IFTA) associated with interstitial inflammation in nonscarred areas (IFTA+i) is associated with poorer graft outcome than inflammation without IFTA or IFTA without inflammation.

Methods: We evaluated if histological categories at week 6 could predict the development of interstitial fibrosis and de novo donor specific anti-HLA antibodies (dnDSA) at 1 year. Biopsies were classified according to Banff criteria as normal (i+t≤1 and ci+ct≤1), inflammation (i+t≥2 and ci+ct≤1), IFTA (i+t≤1 and ci+ct≥2) or IFTA+i (i+t≥2 and ci+ct≥2).

Management of direct-acting antiviral agent failures.

Failure to respond to the approved combinations of multiple direct-acting antiviral agents is relatively low in hepatitis C virus treatment registration studies, with rates of 1% to 7%, depending on the patients' baseline characteristics. In real life, failure is slightly higher, likely because of lower compliance. Treatment failures are usually related to relapse and less often to on-treatment viral breakthrough.

Tenofovir discontinuation after long-term viral suppression in HBeAg negative chronic hepatitis B. Can HBsAg levels be useful?

Background: Recent studies have shown that antiviral treatment discontinuation is safe and associated with virologic remission in HBeAg-negative patients. However, the period of viral suppression and follow-up in these studies was relatively short.

Objectives: To investigate whether continuous viral suppression with tenofovir disoproxil fumarate for more than 7 years is associated with HBsAg loss and sustained response after treatment discontinuation and receiving a full course of hepatitis B vaccination.

Hyperlactatemia and in utero exposure to antiretrovirals: is the control group the clue?

Perinatal antiretroviral (ARV) exposure has been related to hyperlactatemia and lactic acidosis in infants born to HIV-infected mothers. Our objective was to determine the incidence of these conditions during the first year of life in uninfected infants born to HIV-infected mothers and compare the data with infants born to mothers with hepatitis C virus (HCV) infection. We investigated the relationships between hyperlactatemia and neurological and neurodevelopmental disorders by conducting a prospective, comparative cohort study (October 2004 to October 2007) consecutively including children of HIV- and HCV-infected mothers.
