Peritoneal function tests: usefulness of simplified methods.

The Peritoneal Equilibration Test (PET) as standardized by Twardowski (T) and simplified Mass Transfer Coefficients (MTC) as per Garred (G) and Krediet (K) have been employed in our patients to assess: 1) the reproducibility of results, 2) correlation between methods, and 3) usefulness of patient categorization by simplified methods in contrast to PET patterns. We have performed 29 standardized PET (Dianeal 2.5%) in 24 stable CAPD patients. We have collected dialysate samples at 0, 30, 60, 120, 180 and 240 minutes. With this data we were able to calculate the dialysate/plasma ratio for PET, MTC as per Garred and MTC as per Krediet. Our results were not significantly different from data reported by the original authors, except for PET D/P urea at 240': 0.91 +/- 0.07(T) vs. 0.87 +/- 0.08 (our), p < 0.05. In our patients, good correlation was found between PET and MTC for urea, creatinine, and glucose, using both formulae (G and K). Patient categorization as High, High Average, Low Average, and Low by MTCs can well predict PET categorization with acceptable sensitivity and good specificity. We conclude there is good reproducibility of the methods. There is also a close correlation between PET, K and G methods for solute transport evaluation and patient categorization. Simplified methods can be substituted for the more complex ones.

[Athero-embolic nephropathy. Report of 2 cases].

Two cases of athero-embolic nephropathy unrelated with known precipitating factors such as aortic surgery, angiography, anticoagulation or pharmacological fibrinolysis are reported. In one, the histological study additionally disclosed endo-extracapillary proliferative glomerulonephritis. Hypocomplementemia or hypereosinophilia, which some authors consider very characteristic findings, could not be demonstrated in any of the two patients. The difficulties in the diagnosis of athero-embolic nephropathy and the possible indications of renal biopsy are discussed. Emphasis is made on prevention as the best approach to management, no specific treatment being available.

Hypertension and renal artery aneurysm: spontaneous cure.

An 18-year-old man is described with an aneurysm of the left renal artery diagnosed during study for hypertension. Medical treatment achieved control of the blood pressure. The patient voluntarily interrupted treatment 1 1/2 years after initial diagnosis but the blood pressure remained normal. Angiography at that time revealed almost complete thrombosis of the aneurysm and peripheral plasma renin activity returned to normal in contrast to the high figures registered initially (15 ng. per ml., normal values 0.51 to 2.64). The patient had normal blood pressure, received no medication and was on only a salt-free diet 1 year after this event.

Rhabdomyolysis, oedema and arterial hypertension: different syndromes related to topical use of 9-alpha-fluoroprednisolone.

Over a one year period we detected five cases of iatrogenic mineralocorticoidism secondary to topical application of creams containing 9-alpha-fluoro-prednisolone. Although the same product was involved in all cases, the clinical features differed and included two cases of myopathy and hypokalemic rhabdomyolysis, one of oedema and two of arterial hypertension. Discontinuation of treatment and administration of potassium supplements produced a rapid recovery and all patients remain well six months later.
