Alpha 2A-adrenergic receptor polymorphisms were investigated in 55 unrelated Caucasian Catalan individuals. Phenotypes were expressed by alpha 2-adrenoreceptor density and affinity determined by radioligand binding. In addition to the two previously described biallelic restriction fragment length polymorphisms (RFLP) (DraI and Bsu36I) [Hoehe et al 1988; Sun(More)
We evaluated cardiovascular risk factors, morbidity and mortality in patients with lupus nephritis (LN). We prospectively studied 70 consecutive patients with LN, and 70 age- and sex-matched controls with systemic lupus erythematosus (SLE) but no evidence of nephropathy, from 1988 to 1998. Patients were evaluated at entry for hypertension, diabetes,(More)
A 43-year-old man with ankylosing spondylitis (AS) was admitted with proteinuria and renal insufficiency. Coincidental IgA nephropathy and secondary renal amyloidosis were diagnosed on renal biopsy. This is the first case reported of coincidental IgA nephropathy and renal amyloidosis as a cause of renal insufficiency in a patient with AS. Both entities(More)
BACKGROUND AND OBJECTIVE Schizophrenia is a high prevalent disorder associated with huge economic and sanitary costs. Negative symptoms represent the main prognostic factors, thus to identify them is important to design effective guidelines of treatment. The Schedule for the Deficit Syndrome (SDS) is the only validated method to evaluate those symptoms as(More)
Isolated mesangial C3 proliferative glomerulonephritis is a nephropathy poorly defined among glomerular diseases. Clinical picture is characterized by episodes of gross hematuria and/or persistent or recurrent microhematuria and/or proteinuria. Short-term prognosis (less than 3 years) is considered to be benign, although not much information is available in(More)
Several recent studies have focused on the discrepancy between lupus nephropathy and clinical renal involvement and, consequently, question the relevance of renal biopsy in these patients. We analyze the clinical characteristics, histological renal findings and subsequent course of patients with silent renal disease. Renal biopsy was performed in 15(More)
BACKGROUND The aims of the present study were to analyze the clinical and immunologic characteristics of a wide group of patients with systemic lupus erythematosus (SLE) and define homogeneous subgroups with their own characteristics. METHODS A prospective study of 300 patients diagnosed of SLE were studied. These patients were subdivided according to(More)
