Measurement of foveal thickness by optical coherence tomography in adult haemodialysis patients with diabetic nephropathy.

Background: Several studies have demonstrated the efficacy of hemodialysis (HD) on macular edema in diabetic patients.

Objective: To study the effects of a HD session on foveal thickness by optical coherence tomography (OCT) in adult patients with type 2 diabetes mellitus with chronic renal failure (CRF) secondary to stage 5 diabetic nephropathy in HD.

Patients And Methods: We studied 25 eyes of 14 patients who underwent analytical studies and pre-HD and post-HD OCT.

Hypouricemia and tubular transport of uric acid.

Hypouricemia is defined when a serum urate concentration is less than or equal 2.0mg/dl. Differential diagnosis is made by fractional uric acid excretion with the identification of urate transporters and intracellular proteins involved in the tubular transport of uric acid.
