Excretion patterns of kidney related urinary proteins such as lysosomal beta-N-acetylglucosaminidase (beta NAG), brush-border Ala-(Leu-Gly)-aminopeptidase (AAP), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (AP) as well as of IgG, albumin, and alpha-1-microglobulin, were assessed in patients with chronic glomerulonephritis (n = 53), pyelonephritis (n = 27), systemic lupus erythematodes (n = 5), and patients with essential arterial hypertension (n = 18). Excretion of tubular marker enzymes and serumproteins (related to urine creatinine concentration = protein creatinine index) in spontaneously voided second morning urine was significantly higher as compared to the controls (n = 2). Alpha-1-microglobulin was markedly elevated in both pyelonephritis and glomerulonephritis indicating disturbance in tubulointerstitial handling of microglobulins also in cases with primary glomerulopathy. Rise of albumin, IgG, and alpha-1-microglobulin as well as of tubular kidney markers AAP, AP, GGT, and beta NAG in cases with arterial hypertension without preexisting nephropathy support the hypothesis of a defect in charge and size permselectivity in these patients which is probably due to an increase in glomerular capillary perfusion pressure and hyperfiltration.

In 180 children (87 children belonging to a control group, 68 with fever of non-renal origin, and 25 with pyelonephritis) albumin and immunoglobulin G (markers for glomerular dysfunction), alpha-1-microglobulin and beta-NAG (markers for proximal tubular dysfunction) and apolipoprotein A1 (marker of "postrenal' dysfunction) were measured in second-voided morning urine. In children with fever of non-renal origin, glomerular dysfunction was encountered in 8.8%, tubular dysfunction in 17.6% and mixed glomerular-tubular dysfunction in 14.7% of cases. Among children with pyelonephritis, 28% revealed glomerular dysfunction and 44% mixed glomerular-tubular dysfunction. No case of solitary proximal tubular dysfunction was observed in children with pyelonephritis. There were highly significant differences in presence and expression of glomerular dysfunction between children with fever of non-renal origin and children with pyelonephritis (P < 0.0001), whereas with regard to proximal tubular dysfunction, the differences were only moderately significant (beta-NAG: P < 0.01) or of low significance (alpha-1-microglobulin: P < 0.05). This may indicate that morphologic changes occur during interstitial pyelonephritis due to inflammation of glomeruli, resulting in glomerular dysfunction, while proximal tubular dysfunction may additionally be due to fever-associated function processes.

We evaluated the diagnostic utility of urinary alpha1-microglobulin, alpha2-macroglobulin and albumin in the diagnosis of acute prostatitis. We studied 133 men (43 +/- 17 years) with, and a reference population (n=36, 41 +/- 16 years) without, urinary tract infection. Prostatectomy samples were used to study the potential interference between prostatic proteins and protein analysis. Urinary alpha2-macroglobulin/albumin ratio was significantly lower in prostatitis compared to the reference population, cystitis or acute pyelonephritis (p < 0.0001). Low alpha2-macroglobulin concentrations in prostatitis are due to inhibition (p = 0.0001) of the immune reaction between alpha2-macroglobulin in presence of polyclonal rabbit antibodies (used for immunonephelometry) by soluble prostatic proteins (+/- 60 kDa) which appear in urine in acute prostatitis. The urinary alpha1-microglobulin/creatinine ratio diagnoses acute pyelonephritis (sensitivity 100% and specificity 87%) and the urinary alpha2-macroglobulin/albumin ratio diagnoses acute prostatitis (sensitivity 100% and specificity of 90%). Stepwise multinomial logistic regression analysis reveals that urinary alpha1-microglobulin, alpha2-macroglobulin, albumin and creatinine provide optimal differentiation between acute pyelonephritis and acute prostatitis (pseudo R2=0.83; Loglikelihood -30.55, p < 0.000001). In conclusion, the combination of hematuria and absence of urinary alpha-2-macroglobulin is diagnostic for acute prostatitis. Even without hematuria, alpha2-macroglobulin remains lower compared to patients without prostatitis.

The evolution and the relationship between inflammatory and renal-injury markers in women with acute uncomplicated pyelonephritis under antimicrobial therapy were investigated in a prospective study. Markers were measured before and 6 and 24 h after the intravenous administration of 1 g of ceftriaxone. Before treatment, the median levels of all markers except the serum creatinine levels were high. Twenty-four hours after the onset of antibiotic treatment, the C-reactive protein (CRP) level continued to be high, while the serum interleukin-6 (IL-6) levels and the urine IL-6, IL-8, albumin, and immunoglobulin G (IgG) levels decreased significantly. In contrast, serum creatinine and tumor necrosis factor alpha levels and urine N-acetyl-beta-glucosaminidase, alpha1-microglobulin, and beta2-microglobulin levels did not change over time. There was a significant correlation between IL-6 and IL-8 levels and urine albumin and IgG levels (urine albumin and IgG levels are glomerular and urinary tract-injury markers) as well as between serum CRP levels and the levels of the tubular-injury markers. In women with acute pyelonephritis, appropriate antibiotic treatment rapidly decreases serum IL-6 levels and urine IL-6 and IL-8 levels, which correlate well with urine albumin and IgG levels.
