Abstract A case of severe methanol intoxication (1300 mg/L) was associated with markedly increased serum creatinine (490 mg/L) despite normal urea values and the absence of any other signs of renal disease. These values declined progressively to normal, and the patient recovered with no visual impairment. Additional laboratory experimentation suggested that the high creatinine value was probably ascribable to some unknown foreign material(s) in the patient's blood that reacted with the alkaline picrate used in the measurement of creatinine. One of the presumed metabolites of methanol, formaldehyde, reacts with creatinine but the product does not react with picrate. We believe that the foreign material was derived from either commercial preparations of methanol or contaminants in the patient's drinking water.

Rate Of Decline

Many clinical studies of the effects of low-protein and low-phosphorus diets on the course of chronic renal disease have used the rate of decline in renal function to assess the rate of progression. In this report, data from the feasibility phase of the Modification of Diet in Renal Disease Study were used to analyze methods used in other studies. The focus is particularly on the effects of duration of follow-up and of regression to the mean. The findings are summarized as follows. (1) During the mean follow-up period of 14.1 months, rates of decline in glomerular filtration rate, creatinine clearance, and the reciprocal of the serum creatinine concentration were highly variable among individuals, and mean rates of decline were slow. (2) Precision of estimates of individual rates of decline in renal function were relatively low and improved with increasing duration of follow-up. (3) Correlations between rates of decline in creatinine clearance and the reciprocal of the serum creatinine concentration with glomerular filtration rate in individuals were significant but weak and became stronger with increasing duration of follow-up. (4) After entry into the study, mean rate of decline in the reciprocal of the serum creatinine concentration became less negative. The change predicted simply from regression to the mean was 68.4% of the observed change.(ABSTRACT TRUNCATED AT 250 WORDS)

The Mean

A 2-year concurrent drug use evaluation was conducted in 156 patients to determine whether Abelcet (amphotericin B lipid complex injection) was being prescribed according to institution-approved guidelines and to characterize the patient population receiving Abelcet. Eighty-nine patients (57%) had fungal infections documented by chest x-ray, computed tomography, or fungal cultures. Sixty-seven (43%) had clinically suspected fungal infections. The Abelcet mean dose by weight was 5 mg/kg/day (actual body weight). Seventy-one patients (46%) met the established guidelines for use; 85 (54%) did not. Premedication was given to 64% of the patients; only 15 patients (10%) experienced documented fever and chills. A total of 72 patients (46%) died during therapy. Of the 75 patients who completed therapy in the hospital, 41 were switched to conventional amphotericin B, fluconazole, or itraconazole following a decrease in serum creatinine concentration, and 34 did not receive further antifungal therapy. The mean length of Abelcet therapy was 11 days. The mean increase in serum creatinine concentration at discontinuation of therapy was 0.2 mg/dL. Continued monitoring of Abelcet use was recommended and established guidelines were reaffirmed. Hydration with normal saline before and after dosing was suggested to help improve renal function, and dopamine was recommended to increase renal blood flow.

Renal Uptake

Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations > 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow < 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 ± 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 ± 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis.
