The chronic lymphocytic leukemia (CLL) immunoglobulin repertoire is biased and characterized by the existence of subsets of cases with closely homologous ("stereotyped") complementarity-determining region 3 (CDR3) sequences. In the present series, 201 (21.9%) of 916 patients with CLL expressed IGHV genes that belonged to 1 of 48 different subsets of(More)
The responsiveness and diversity of peripheral B-cell repertoire decreases with age, possibly because of B-cell clonal expansions, as suggested by the incidence of serum monoclonal immunoglobulins and of monoclonal chronic lymphocytic leukemia (CLL)-like B lymphocytes in clinically silent adults. We phenotyped peripheral blood cells from 500 healthy(More)
We studied immunoglobulin variable heavy-chain (IGHV) repertoire and mutational status in 553 patients with chronic lymphocytic leukemia (CLL) from the Mediterranean area to gain insight into the potential pathogenetic role of antigenic stimulation. The most commonly represented IGHV genes mirrored the usage of normal B cells, with the exception of(More)
BACKGROUND Hypoxia and snoring-related mechanical trauma contribute to airway inflammation in obstructive sleep apnoea (OSA). Increased exhaled nitric oxide (FENO), an airway inflammation marker, has been reported in OSA patients. We propose the measure of NO in the oral cavity (oNO) as marker of oropharyngeal inflammation in OSA. METHODS We compared oNO(More)
The natural history of B-chronic lymphocytic leukemia (CLL) is not entirely explained by intrinsic defects of the neoplastic cell, but is also favored by microenvironmental signals. As CLL cells retain the capacity to respond to CD40 ligand (CD40L) and as CD4(+) T cells are always present in involved tissues, we asked whether malignant CLL cells might(More)
BACKGROUND The role that nasal nitric oxide (nNO) plays in sinonasal diseases is increasingly appreciated. OBJECTIVE To test the diagnostic value of measuring nNO levels in a symptomatic population undergoing evaluation for potential chronic rhinosinusitis (CRS). METHODS Of the patients referred to an outpatient allergy clinic for persistent nasal(More)
Chronic lymphocytic leukemia (CLL) has a variable clinical course. CD38 expression and IgV(H) gene mutational status are independent predictors of prognosis, but their relationships and the CD38 cutoff level are unknown. Using cytofluorography, we analyzed CD38 in 148 patients, in 108 of whom we were able to evaluate IgV(H) mutations, make correlations with(More)
SUMMARY A total of 507,671 people > or =65 experienced hip fractures between 2000 and 2005. In 2005, 94,471 people > or =65 were hospitalized due to hip fractures, corresponding to a 28.5% increase over 6 years. Most fractures occurred in patients > or =75 (82.9%; n = 420,890; +16% across 6 years), particularly in women (78.2%; n = 396,967). INTRODUCTION(More)
To gain further insight into the mechanism of cell photostimulation by laser light, both RNA and protein synthesis were measured in mitochondria irradiated with the low power continuous wave He-Ne laser (Energy dose: 5 Joules/cm2). Following mitochondrial irradiation, both the rate and amount of incorporation of alpha-[32P]UTP and L-[35S]methionine, used to(More)
BACKGROUND Rhinitis and asthma represent the manifestation of one syndrome. Our hypothesis is that in patients with symptoms of persistent rhinitis, lower airway inflammation, lower respiratory symptoms, and lung function abnormalities compatible with asthma are more frequently associated with the diagnosis of allergic rhinitis (AR) and chronic(More)
