RESULTS: In the 10 patients with lupus nephritis, urinary NAG before treatment was 16.9 ± 13.39 U/gCr (P = 0.005 compared with controls). NAG in controls was 1.73 ± 0.51 U/gCr. Proteinuria before treatment was 3.84 ± 1.93 g/24 h. [ncbi.nlm.nih.gov]

The aim of the present study was to determine whether the comorbidity of RTD, as assessed by UBCR, predicts cardiac prognosis in patients with CHF. [circheartfailure.ahajournals.org]

Prognosis Most patients die within the first year of life despite supportive care for metabolic acidosis and cholestasis and those surviving longer show cirrhosis and severe developmental delay. [orpha.net]

Treatment: High doses of bicarbonate are required but the prognosis is good. Correcting acidosis and low potassium levels allows normal growth and prevents bone disease; however, vitamin D supplements may also be required. [patient.info]

Measuring tubular secretion as an independent marker of kidney function may provide insight into kidney disease etiology and prediction of adverse outcomes. [digital.lib.washington.edu]

Etiology Mutations in the VPS33B gene (15q26.1), involved in intracellular protein trafficking and membrane fusion, have been found in 75% of ARC families, as well as mutations in the VIPAR gene (C14ORF133), encoding a protein that complexes with VPS33B [orpha.net]
