Use of intravenous immunoglobulins in Lyell syndrome: Experience of three cases
1996
We present our experience of treatment of the last three cases of Lyell syndrome we have observed. They are three female children, aged between 16 months and 3 years, who showed many features in common with severely burnt patients (large exuding lesions, severe reduction of circulating plasmatic volume, large denuded body surfaces, severe tendency to infections, ...). Therefore, together with the already known scheme of treatment (corticosteroids, correction of hydroelectrolitic balance, antimicrobials), we decided to use intravenous Immunoglobulins (IVIG), which had been already positively used in severely burnt patients. The favorable evolution of the affection in all three cases and the …
Cryptic Insertions Of The Immunoglobulin Light Chain Enhancer Region Near CCND1 In T(11;14)-Negative Mantle Cell Lymphoma
2019
Cyclin D1+ mantle cell lymphoma (MCL) is molecularly characterized by the t(11;14)(q13;q32) or rearrangements of CCND1 gene with the immunoglobulin (IG) light chains.1,2 Most MCL can be diagnosed based on the characteristic pathologic features and cyclin D1 expression without the need for demonstrating the genetic translocation. However, in cases with atypical morphologic or phenotypic features other B-cell neoplasms that sometimes also have cyclin D1 positivity may be in the differential diagnosis.1 In these situations the detection of the CCND1 rearrangements may assist in the diagnosis since most other lymphomas do not carry translocations of the gene.3-7 A subset of plasma cell myelomas…
Immunofluorescence Analysis as a Diagnostic Tool in a Spanish Cohort of Patients with Suspected Primary Ciliary Dyskinesia
2020
Primary ciliary dyskinesia (PCD) is an autosomal recessive rare disease caused by an alteration of ciliary structure. Immunofluorescence, consisting in the detection of the presence and distribution of cilia proteins in human respiratory cells by fluorescence, has been recently proposed as a technique to improve understanding of disease-causing genes and diagnosis rate in PCD. The objective of this study is to determine the accuracy of a panel of four fluorescently labeled antibodies (DNAH5, DNALI1, GAS8 and RSPH4A or RSPH9) as a PCD diagnostic tool in the absence of transmission electron microscopy analysis. The panel was tested in nasal brushing samples of 74 patients with clinical suspic…
The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…
2004
One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…
