Hereditary spherocytosis (HS) is a very heterogenous condition both at clinical and biochemical level. To establish the relationship between these aspects we performed a clinical and biochemical study in 87 Italian HS subjects. Patients were divided into three groups based on clinical severity (mild, typical and severe) and into five subgroups based on(More)
The present study was aimed at verifying the occurrence, if any, of in vivo oxidative DNA damage in FA homozygotes, their parents and siblings. 8-Hydroxy-2'-deoxyguanosine (8-OHdG) was measured, by HPLC/EC, in DNA from circulating blood leucocytes from FA homozygotes and their relatives and compared with a group of paediatric and adult healthy subjects. The(More)
A kindred with hereditary spherocytosis and beta-thalassaemia trait was identified. Detailed studies of the red cell membrane proteins on polyacrylamide gels with sodium dodecyl sulphate (SDS-PAGE) demonstrated the presence of band 3 (anion transporter) deficiency in all HS subjects (20-25% reduction) whereas spectrin content was in the normal range. The(More)
We describe three Italian subjects from two unrelated families affected with isolated hereditary spherocytosis (HS) without other clinical abnormalities, associated with partial spectrin and ankyrin deficiency. In both families the propositus has normal biological parents, and thus appears to be the result of a new mutation; in one of them the disease is(More)
Scope Th e journal/newsletter aims to provide a basis for conservation information relating to the primates of the Neotropics. We welcome texts on any aspect of primate conservation, including articles, thesis abstracts, news items, recent events, recent publications , primatological society information and suchlike. Contributions Manuscripts may be in(More)
We report a new mutation responsible for nonhemolytic hereditary elliptocytosis (HE). The proband displayed an impaired spectrin self-association and an increase of the alpha I 74-kD fragment (alpha I/74 abnormality). The responsible mutation occurred in exon 2 of spectrin alpha-gene: alpha 34 Arg-->Trp (CGG-->TGG), defining spectrin Genova. In Trans to(More)
BACKGROUND Natural rubber latex (NRL) allergy is a worldwide problem. Although prevention is sufficient to reduce sensitization, prolonged avoidance is needed to prevent resensitization or adverse reactions on re-exposure. OBJECTIVES This double-blind, placebo-controlled study was conducted to determine the efficacy of sublingual immunotherapy (SLIT) with(More)
BACKGROUND Hereditary spherocytosis encompasses a heterogenous group of inherited disorders due to alteration of r.b.c. surface/volume ratio. Spectrin deficiency is the most common observed defect. We analyzed a case of HS associated with band 3 deficiency without spectrin reduction. METHODS In the study of a family originating from southern Italy, we(More)
