RESUMO
INTRODUCTION: Lowe Syndrome, or Oculocerebrorenal Dystrophy (OCRL), has a recessive inheritance linked to X chromosome. It presents cataracts and glaucoma, delay in neuropsychomotor development, cognitive deficits, and renal Fanconi syndrome. OBJECTIVE: Describe five patients with OCRL, attended at Tubulopathy outpatient clinic. METHOD: We performed a retrospective assessment of 5 male patient clinical charts of OCRL patients. RESULTS: Mean age at first consultation was 76.5 and mean follow up interval was 30.5 months (8-53 months). Symptoms and clinical signs included cataracts and nystagmus. Neuropsychomotor development and weight and height deficits were present in whole cases, as well as polyuria, polydipsia, and intestinal constipation, metabolic acidosis, phosphaturia, bicarbonaturia, proteinuria, hypercalciuria, hyperuricosuria. Nephrocalcinosis was identified in one, renal lithiasis in three, and reduced kidney size in two patients. We found pathological fractures and rachitism in two, bone rarefaction and delay of bone age in all of the patients. One patient presented a reduction in the rhythm of glomerular filtration. Therapeutically, all patients received alkali, phosphorus and vitamin D reposition in addition to a dietary orientation adequate to their needs. CONCLUSION: This study emphasizes the importance of early diagnosis and medico-nutritional followup, to avoid complications related to metabolic disturbances.
