Very few patients with familial hypomagnesemia, hypercalciuria and nephrocalcinosis have been described. Information about clinical course, familial studies or evolution after renal transplantation is very scant. We have studied eight patients with this syndrome who belong to five different families. The mean age at diagnosis was 15 +/- 7 years (5 to 25(More)
We studied renal involvement in 42 children with mitochondrial diseases (MDs). The diagnosis of MD was established by morphological, biochemical, and molecular genetic criteria. Renal disease was considered when patients had renal failure, nephrotic syndrome, Fanconi’s syndrome or any symptomatic renal alteration. Mild tubular disorder was established if(More)
BACKGROUND AND OBJECTIVES Our aim was to evaluate the growth-promoting effect of growth hormone (GH) treatment in infants with chronic renal failure (CRF) and persistent growth retardation despite adequate nutritional and metabolic management. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The study design included randomized, parallel groups in an open,(More)
BACKGROUND Dent's disease is a rare renal tubular disorder characterized by low-molecular weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis, rickets and eventual renal failure. The selective loss of low-molecular weight proteins points to a defect of the proximal tubule, where filtered proteins are normally reabsorbed by endocytosis. The(More)
BACKGROUND Cysteamine has improved survival and prognosis in cystinosis. Increasing numbers of patients reach adulthood and face new challenges such as compliance that wanes over time. The aim of this study was to evaluate adherence to cysteamine treatment in a group of cystinotic patients in Spain in an attempt to identify potential therapy pitfalls and(More)
Mutations in the assembly chaperone BCS1L constitute a major cause of mitochondrial complex III deficiency. We studied the presence of BCS1L mutations in a complex III-deficient patient with metabolic acidosis, liver failure, and tubulopathy. A previously reported mutation, p.R56X, was identified in one BCS1L allele, and two novel heterozygous mutations,(More)
Dent's disease is an X-linked proximal tubulopathy characterized by low-molecular-weight proteinuria, hypercalciuria, nephrocalcinosis, nephrolithiasis and progressive renal failure. This disorder is frequently caused by mutations in the CLCN5 gene encoding the electrogenic chloride/proton exchanger ClC-5. Occasionally, Dent's disease has been associated to(More)
