Efficacy and safety of hizentra®, a new 20% immunoglobulin preparation for subcutaneous administration, in pediatric patients with primary immunodeficiency.

Subcutaneous IgG treatment for primary immunodeficiencies (PI) is particularly well suited for children because it does not require venous access and is mostly free of systemic adverse events (AEs). In a prospective, open-label, multicenter, single-arm, Phase III study, 18 children and five adolescents with PI were switched from previous intravenous (IVIG) or subcutaneous (SCIG) IgG treatment to receive dose-equivalent, weekly subcutaneous infusions of Hizentra(®) for 40 weeks. Mean IgG trough levels were maintained in patients previously on SCIG, or increased in those previously on IVIG, regardless of age.

Clinical presentation and personality factors are predictors of the response to treatment in patients with functional dyspepsia; a randomized, double-blind placebo-controlled crossover study.

The role of psychological factors or symptom pattern for the response to treatment in patients with unexplained (functional) dyspepsia is unknown. We hypothesized that patients with reflux- and ulcer-like symptoms would be more likely to respond to acid-lowering therapy, while psychological disturbances would be associated with a less favorable response to treatment. Seventy-eight patients with a diagnosis of functional dyspepsia were recruited and 75 completed the trial.
