The GFR and other kidney function assessments were measured during a 24-hour period.
Data collected per patient encompasses admission demographic data, daily morning hemodynamic parameters, daily laboratory values specific for kidney function, assessments of fluid balance including net fluid in and net fluid out, and use of nephrotoxins or diuretic agents.
This confirmed the impossibility to distinguish among these conditions solely on the basis of kidney function assessment or proteinuria.
Plasma BUN and Cr levels were measured for kidney function assessment, while ALP, T.Bil, D.Bil, GGT, ALB, ALT, and AST were done for liver function evaluation.
Furthermore, kidney function assessment is not included in the routine work-up of pregnant women according to the main current pregnancy management guidelines, including the Italian ones and the well-known NICE ones [ 38, 39].
The overall results of the kidney-function assessment in this study show that the relative change in the glomerular filtration rate was positive in response to the increase in daily protein ingestion of 18.1 g achieved with the ricotta cheese.
Because we had access to laboratory data allowing a gold standard assessment of kidney function, we primarily assessed the presence of chronic kidney disease using estimated glomerular filtration rate (eGFR) and albuminuria rather than administrative data.
Glomerular filtration rate (GFR) is considered the best measure of kidney function, but repeated assessment is not feasible in most research studies.
In critically ill patients with early AKI: Urinary clearance of creatinine should not be used as a reference method when validating new methods for assessing kidney function Estimating equations for assessment of GFR perform poorly.
Physical exams, toxicity assessments and laboratory assessments (including electrolytes, kidney function, liver function, complete blood count and fasting lipids) were obtained every 4 weeks.
Particularly, patients receiving tenofovir may benefit from frequent assessments of kidney function, serum phosphate levels, and urinalyses to monitor for early signs of nephrotoxicity [ 6, 30].
