The German National Registry of Primary Immunodeficiencies (2012-2017).

The German PID-NET registry was founded in 2009, serving as the first national registry of patients with primary immunodeficiencies (PID) in Germany. It is part of the European Society for Immunodeficiencies (ESID) registry. The primary purpose of the registry is to gather data on the epidemiology, diagnostic delay, diagnosis, and treatment of PIDs.

Lung disease in STAT3 hyper-IgE syndrome requires intense therapy.

Background: Pulmonary complications are responsible for high morbidity and mortality rates in patients with the rare immunodeficiency disorder STAT3 hyper-IgE syndrome (STAT3-HIES). The aim of this study was to expand knowledge about lung disease in STAT3-HIES.

Methods: The course of pulmonary disease, radiological and histopathological interrelations, therapeutic management, and the outcome of 14 STAT3-HIES patients were assessed.

Hematopoietic Stem Cell Transplantation as Treatment for Patients with DOCK8 Deficiency.

Background: Biallelic variations in the dedicator of cytokinesis 8 (DOCK8) gene cause a combined immunodeficiency with eczema, recurrent bacterial and viral infections, and malignancy. Natural disease outcome is dismal, but allogeneic hematopoietic stem cell transplantation (HSCT) can cure the disease.

Objective: To determine outcome of HSCT for DOCK8 deficiency and define possible outcome variables.

Efficacy and safety of trimodulin, a novel polyclonal antibody preparation, in patients with severe community-acquired pneumonia: a randomized, placebo-controlled, double-blind, multicenter, phase II trial (CIGMA study).

Purpose: The CIGMA study investigated a novel human polyclonal antibody preparation (trimodulin) containing ~ 23% immunoglobulin (Ig) M, ~ 21% IgA, and ~ 56% IgG as add-on therapy for patients with severe community-acquired pneumonia (sCAP).

Methods: In this double-blind, phase II study (NCT01420744), 160 patients with sCAP requiring invasive mechanical ventilation were randomized (1:1) to trimodulin (42 mg IgM/kg/day) or placebo for five consecutive days. Primary endpoint was ventilator-free days (VFDs).

TNFRSF1A and MEFV mutations in childhood onset multiple sclerosis.

To investigate frequency and phenotype of TNFRSF1A and MEFV mutations in childhood-onset multiple sclerosis (MS). Twenty-nine clinically well characterized patients were investigated for mutations in exons 2, 3, 4, and 6 of the TNFRSF1A gene and in exons 2, 3, 9, 10 of the MEFV gene. Standardized morbidity ratio (SMR) was used to assess whether the number of observed mutations was higher than expected.
