Acquired and Innate Immunity Impairment and Severe Disseminated Mycobacterium genavense Infection in a Patient With a NF-κB1 Deficiency.

Background: NF-κB1 is a master regulator of both acquired and innate responses. NFKB1 loss-of-function mutations elicit a wide clinical phenotype with asymptomatic individuals at one end of the spectrum and patients with common variable immunodeficiency, combined immunodeficiency or autoinflammation at the other. Impairment of acquired and innate immunity and disseminated Mycobacterium genavense infection expands the clinical and immunological phenotype of NF-κB1 deficiency. Objective: Functional and molecular characterization of a patient with a novel phenotype of NF-κB1 deficiency. Methods: Circulating T, B, dendritic cell subsets and innate or unconventional T-cells were quantified. The cytokine production in stimulated whole blood samples was assessed and molecular characterization by next generation sequencing and gene expression assays were also performed. Results: We report a patient presenting with features of combined immunodeficiency (CID) and disseminated Mycobacterium genavense infection. Sequencing of genomic DNA identified a novel synonymous mutation (c.705G > A) in NFKB1 gene which resulted in exon 8 skipping and haploinsufficiency of the NF-κB1 subunit p50. The susceptibility to atypical mycobacterial infection has not been previously reported and may be the result of a dendritic cell deficiency. A selective deficiency of circulating follicular helper T (cTFH) cells responsible for mediating the differentiation of naive B cells into memory and plasma cells was also present in the patient. It could affect the maturation of innate or unconventional T cells where NF-κB1 could also be involved. Conclusion: These findings showed that the role of NF-κB1 in humans could be critical for the development of acquired and innate immunity and further highlights the role of human T cells in anti-mycobacterial immunity.

Extreme Phenotypes With Identical Mutations: Two Patients With Same Non-sense NHEJ1 Homozygous Mutation.

Cernunnos/XLF deficiency is a rare primary immunodeficiency classified within the DNA repair defects. Patients present with severe growth retardation, microcephaly, lymphopenia and increased cellular sensitivity to ionizing radiation. Here, we describe two unrelated cases with the same non-sense mutation in the NHEJ1 gene showing significant differences in clinical presentation and immunological profile but a similar DNA repair defect.

The effect of the European traditional use directive on the register of herbal medicinal products in Spain / Efecto en España de la directiva Europea de uso tradicional sobre el registro de medicamentos a base de plantas

Background: Directive 2004/24/EC, which came into force in 2011, created new regulatory requirements for traditional herbal medicines (THM). This study compared the Spanish THM registry before and after the Directive came fully into force in 2011. Methods: We consulted the herbal medicinal plant and drug catalogues (General Council of the Official Colleges of Pharmacists), the website of the European Medicines Agency (EMA), and retail web sites. Results: Of 315 THM (from 39 companies) licensed in Spain in 2010, only 48 (10 companies) remained licensed in 2013, mainly due to their withdrawal: the EMA had received just 123 applications from Spain and at least 34% formerly licensed THM had shifted to the less strictly regulated food sector, while up to 54% might have disappeared from the market. However, there is still a significant presence of retail websites making illegal health claims. Conclusion: In Spain, the public health benefits of the Directive 2004/24/EC might be less than expected (AU)

Antecedentes: En 2011 entró totalmente en vigor la Directiva 2004/24/CE, que impone nuevos requerimientos a los medicamentos tradicionales a base de plantas. Este trabajo analiza el efecto sobre su registro en España. Métodos: Se consultaron los catálogos de plantas medicinales y de medicamentos (CGCOF), la página web de la Agencia Europea del Medicamento (EMA) y sitios de venta en Internet. Resultados: De los 315 medicamentos a base de plantas autorizados en 2010, procedentes de 39 compañías; solo quedaban 48 (10 compañías) en 2013 por renuncia de la mayoría: sólo 123 solicitudes fueron recibidas a la EMA y al menos un 34% se pasó al sector de alimentación (menos estrictamente regulado). Hasta un 54% podría no comercializarse actualmente. Sin embargo, existe una presencia significativa de sitios web anunciando ilegalmente propiedades saludables para sus productos. Conclusión: Los beneficios de la Directiva 2004/24/CE para la salud pública española podrían ser menos de los esperados (AU)
