Efficacy and safety of gene therapy with onasemnogene abeparvovec in children with spinal muscular atrophy in the D-A-CH-region: a population-based observational study.

Background: Real-world data on gene addition therapy (GAT) with onasemnogene abeparvovec (OA), including all age groups and with or without symptoms of the disease before treatment are needed to provide families with evidence-based advice and realistic therapeutic goals. Aim of this study is therefore a population-based analysis of all patients with SMA treated with OA across Germany, Austria and Switzerland (D-A-CH).

Methods: This observational study included individuals with Spinal Muscular Atrophy (SMA) treated with OA in 29 specialized neuromuscular centers in the D-A-CH-region.

Immune correlates of protection of the four-segmented Rift Valley fever virus candidate vaccine in mice.

Rift Valley fever (RVF) is a mosquito-borne zoonotic disease caused by RVF virus (RVFV). RVFV infections in humans are usually asymptomatic or associated with mild febrile illness, although more severe cases of haemorrhagic disease and encephalitis with high mortality also occur. Currently, there are no licensed human vaccines available.

Phenylbutyrate Treatment in a Boy with MCT8 Deficiency: Improvement of Thyroid Function Tests and Possible Livertoxicity.

Context: Monocarboxylate transporter 8 (MCT8) deficiency is a rare X-chromosomal inherited disease leading to severe cognitive impairment, muscular hypotonia and symptoms of peripheral thyrotoxicosis. Experimental approaches aiming to functionally rescue mutant MCT8 activity by the chemical chaperone phenylbutyrate (PB) demonstrated promising effects in vitro for several MCT8 missense mutations.

Objective: The objective was to evaluate biochemical and clinical effects of PB in doses equivalent to those approved for the treatment of urea cycle disorders in a boy with MCT8 deficiency due to a novel MCT8 missense mutation c.
