Paricalcitol as an Antiproteinuric Agent Can Result in the Deterioration of Renal and Heart Function in a Patient with Fabry Disease.

BACKGROUND Fabry disease is a rare and progressive X-linked inherited disorder of glycosphingolipid metabolism that is due to deficient or absent lysosomal a-galactosidase A activity. Among its other associated signs and symptoms, patients present with renal failure and proteinuria, which are markers of disease progression. Renin-angiotensin-aldosterone system (RAAS) blockers can slow the progression of chronic renal failure and proteinuria.

Urinary immunoglobulin G to albumin ratio and N-Acetyl-Beta-D-Glucosaminidase as early predictors of therapeutic response in ANCA-associated glomerulonephritis.

Background: The aim of our study was to evaluate the prognostic value of glomerular and tubular proteinuria and tubular enzymuria as early indicators of therapeutic response to induction therapy with i.v. pulse cyclophosphamide (CyC) and methylprednisolone (MP) in patients with antineutrophil cytoplasmic antibody (ANCA) associated glomerulonephritis.

Electrocardiographic findings in children with erythema migrans.

Objective: To assess electrocardiographic findings in children with erythema migrans and to compare them with findings obtained in a healthy control group of comparable age and with a similar proportion of boys and girls.

Methods: Electrocardiograms were carried out in 147 children under the age of 15 years before treatment with antibiotics for erythema migrans (solitary 68 patients, multiple 79 patients) and in the control group of 148 healthy children.

Results: Abnormal electrocardiographic findings were detected more often in healthy children than in patients (14% versus 5%; P = 0.
