We investigated the effects of 3 days treatment with acetazolamide 250 mg three times daily on kidney function in 8 Type 1 (insulin-dependent) diabetic patients with nephropathy, and in 7 healthy subjects in a double-blind placebo controlled cross-over study. Glomerular filtration rate and extracellular fluid volume were measured with the single injection 51Cr-EDTA technique and fluid flow rate from the proximal tubules was determined by measurement of the renal lithium clearance. A 24% decline in glomerular filtration rate was observed in both groups during acetazolamide treatment (control subjects: 108 +/- 11 vs 82 +/- 9 ml/min, p less than 0.02, diabetic patients: 71 +/- 19 vs 54 +/- 14 ml/min, p less than 0.01). The renal lithium clearance (ml/min) remained about the same (control subjects: 22 +/- 6 vs 27 +/- 8, NS, diabetic patients: 14 +/- 5 vs 15 +/- 4, NS). Absolute proximal tubular reabsorption of water (ml/min) was reduced by about one-third (control subjects: 85 +/- 11 vs 56 +/- 7, p less than 0.02, diabetic patients: 55 +/- 17 vs 37 +/- 6, p less than 0.02), and fractional proximal reabsorption of water and sodium (%) declined (control subjects: 79 +/- 5 vs 67 +/- 8, p less than 0.02, diabetic patients: 79 +/- 5 vs 72 +/- 6, p less than 0.02). Renal sodium clearance and distal fractional reabsorption of sodium was unchanged. Extracellular fluid volume declined by 10% in both groups (p less than 0.02). Albuminuria and fractional albumin clearance decreased significantly in the nephropathic patients (p less than 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)

D003922	Diabetes Mellitus, Type 1	A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.

D003928	Diabetic Nephropathies	KIDNEY injuries associated with diabetes mellitus and affecting KIDNEY GLOMERULUS; ARTERIOLES; KIDNEY TUBULES; and the interstitium. Clinical signs include persistent PROTEINURIA, from microalbuminuria progressing to ALBUMINURIA of greater than 300 mg/24 h, leading to reduced GLOMERULAR FILTRATION RATE and END-STAGE RENAL DISEASE.

D000086	Acetazolamide	One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition.
