Social Resources for Transplanted Children and Families in European Union Hospitals of ERN TransplantChild.

Social well-being is an intrinsic part of the current concept of health. In the context of chronic disease, there are many challenges we face in order to provide social well-being to patients and their families, even more if we talk about rare diseases. TransplantChild, a European Reference Network (ERN) in paediatric transplantation, works to improve the quality of life of transplanted children. It is not possible to improve the quality of life if the human and material resources are not available. With this study, we want to identify the economic aids, facilities, services, and financed products that are offered to families in different European centres. We also want to find out who provides these resources and the accessibility to them. We designed an ad hoc survey using the EU Survey software tool. The survey was sent to representatives of the 26 ERN members. In this article we present the results obtained in relation to two of the aspects analysed: long-term financial assistance and drugs, pharmaceuticals and medical devices. Some resources are equally available in all participating centres but there are significant differences in others, such as education aids or parapharmacy product financing. A local analysis of these differences is necessary to find feasible solutions for equal opportunities for all transplanted children in Europe. The experience of centres that already provide certain solutions successfully may facilitate the implementation of these solutions in other hospitals.

The allele MICB 0050204, over-represented in the Caucasian population, has an additional exon resulting from a new splice junction sequence.

We report that the allele MICB 0050204(1) allele, present in the majority of the Spanish population (70% of healthy controls) is characterized by the presence of an extra exon found between the sequence corresponding to exon 1 and 2. This is generated by a dinucleotide polymorphism in the first MICB intron that introduces a new splice junction, which can generate, by alternative splicing, transcripts with an additional exon. This new exon contains a premature stop codon and therefore the transcript does not produce a functional protein.

Contribution of KIR3DL1/3DS1 to ankylosing spondylitis in human leukocyte antigen-B27 Caucasian populations.

Killer cell immunoglobulin-like receptors (KIRs) and human leukocyte antigen (HLA) loci are both highly polymorphic, and some HLA class I molecules bind and trigger cell-surface receptors specified by KIR genes. We examined whether the combination of KIR3DS1/3DL1 genes in concert with HLA-B27 genotypes is associated with susceptibility to ankylosing spondylitis (AS). Two HLA-B27-positive Caucasian populations were selected, one from Spain (71 patients and 105 controls) and another from the Azores (Portugal) (55 patients and 75 controls). All were typed for HLA-B and KIR (3DS1 and 3DL1) genes. Our results show that in addition to B27, the allele 3DS1 is associated with AS compared with B27 controls (p < 0.0001 and p < 0.003 in the Spanish population and Azoreans, respectively). We also observed that the association of KIR3DS1 to AS was found in combination with HLA-B alleles carrying Bw4-I80 in trans position in the Spanish population (30.9% in AS versus 15.2% in B27 controls, p = 0.02, odds ratio (OR) = 2.49) and in Azoreans (27.2% in AS versus 8.7% in B27 controls, p = 0.01, OR = 4.4 in Azoreans). On the other hand, 3DL1 was decreased in patients compared with B27 controls (p < 0.0001 in the Spanish population and p < 0.003 in Azoreans). The presence of this allele in combination with Bw4-I80 had a protective effect against the development of AS in the Spanish population (19.7% in AS, 35.2% in B27 controls; p = 0.03, OR = 0.45). The presence of KIR3DS1 or KIR3DL1 in combination with HLA-B*27s/HLA-B Bw4-I80 genotypes may modulate the development of AS. The susceptibility to AS could be determined by the overall balance of activating and inhibitory composite KIR-HLA genotypes.
