Several studies indicate genetic involvement of Th2 cytokines in allergic diseases. Interleukin (IL)-13 has been mapped to the cytokine cluster on chromosome 5q31-33, which has been associated with atopic conditions. Recently, an association was reported between the T allele in a promoter polymorphism in the IL-13 gene (C to T exchange) at position -1055 and allergic asthma in a population study in the Netherlands. This observation was apparently confirmed in a case-control study using probands and spouses from a Dutch asthma family study, but the polymorphism in that study was reported to occur at position -1111. In the present study, we established that this polymorphism is located at position -1024 relative to the ATG translation initiation codon, and investigated whether it confers a genetic predisposition to atopic conditions and the Th1 condition multiple sclerosis (MS) in Caucasian subjects. We confirmed the association between the IL-13 -1024TT genoype and inhalation allergy (P = 2.4E-02). By combining the data from the three studies, we demonstrated a strong association (P = 1.09E-05) between the IL-13 -1024 marker and inhalation allergy. Furthermore, we showed for the first time that this association also exists in atopic dermatitis (P = 2.0E-02). No association with MS was found.

Following the bone marrow transplantation, the child had developed severe pulmonary fibrosis. Surgery and the early postoperative course have been uncomplicated. Immunosuppression with corticosteroids was administered for a short period, after which all immunosuppressive treatment was discontinued.The operation and the outcome are described both in the donor and recipient. Rehabilitation was slow, but one year later the patient is doing well.
As the understanding of the autoimmune inflammatory response in multiple sclerosis (MS) expands, polymorphic genes involved in this process become possible candidates that may determine the severity of disease. Therefore, three candidate genes DRB1*1501, CCR5 and apolipoprotein E (APOE) were examined in a population-based patient sample (n = 70) to assess an association between disease progression measured by clinical disability and MRI parameters. The total lesion area (TLA) on T2-weighted images was measured with a semi-automated threshold technique. Patients with the CCR5delta32 allele showed a non-significant trend towards a smaller lesion burden (TLA/years duration), but were not associated to a milder EDSS/years duration. Our data support previous assumptions of a modulation of severity in MS by the CCR5delta32 genotype, which may convey less inflammation and tissue destruction. Carriers of the DRB1*1501 and APOE-epsilon4 allels did not reveal more severe disease progression, neither by the EDSS/years of duration nor by the TLA/years duration. This study was performed on a population-based sample in a genetically homogeneous Danish population but, due to the limited number of patients examined, weak associations between candidate genes and disease variables cannot be excluded.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
