The association of xanthogranulomatous pyelonephritis and systemic amyloidosis is extremely rare. To our knowledge, despite innumerable cases of xanthogranulomatous pyelonephritis reported in the literature, this association has been described on only 2 occasions. Clinical, analytical and radiographic findings can be highly suggestive of the diagnosis. We report on 2 patients with xanthogranulomatous pyelonephritis, systemic amyloidosis and the nephrotic syndrome: 1 died 4 1/2 years after diagnosis and 1 was stable with good general health 3 years after diagnosis. The clinical aspects as well as the treatment given to both patients are discussed. We describe the natural history of an association that due to its rarity is not currently well known.

Urinary glycyl-prolyl dipeptidyl aminopeptidase (GP-DAP) activity was measured in 18 healthy adults and 252 patients with urological diseases. The GP-DAP activity was significantly higher in patients with prostatic cancer, bladder cancer or renal cancer and also in patients with acute prostatitis or pyelonephritis than in healthy adults. GP-DAP activity was also studied during anticancerous chemotherapy and proved to be a sensitive parameter for renal damage as are urinary N-acetyl-beta-D-glucosaminidase, alanine aminopeptidase, beta 2-microglobulin, alpha 1-microglobulin, and albumin. The analysis of tissue activities suggested that GP-DAP was located not only in the renal parenchyma but also in the prostate and seminal vesicles.

We are reporting 2 cases of xanthogranulomatous pyelonephritis in boys of 7 and 2 year-old. The inflammatory lesion had extended to perirenal tissues and appeared as a lumbar abscess in case 1. The kidneys affected were diffusely compromised by the lesion. Both cases showed Proteus mirabilis after microbiologic cultures. Definitive diagnosis was done by pathology examination. Nephrectomy was curative.

++Non-ezymatic lipid peroxidation (LP) and total lipids (TL) in serum and erythrocytic membranes were studied in 42 hypertensive subjects and 35 chronic sufferers with pyelonephritis accompanied by arterial hypertension. The measurements performed at different phases of the clinical course provided evidence in favour of possible application of LP and TL tests in differentiating essential hypertension from chronic pyelonephritis with arterial hypertension.

The evaluation of hormonal adaptation of the fetoplacental unit (FPU) in pregnant women with somatic and obstetric complications has demonstrated 4 patterns of adaptation: normal, stressful, maladaptive and unstable. The distribution of FPU adaptive responses across diagnostic groups correlated with types of diseases and their duration in pregnant women. Controlled heart diseases, chronic pyelonephritis without exacerbations, mild toxemia were mostly associated with a normal FPU adaptation. Decompensated heart disease, acute episodes of chronic pyelonephritis, deteriorating toxemia, decompensated diabetes mellitus produced functional activation of FPU hormones. Pregnant women with stable hypertension in the presence of moderately severe toxemia and essential hypertension showed hormonal FPU maladaptation. Differential evaluation of FPU adaptation in pregnant women with somatic and obstetric diseases provides a guide to a range and sequence of interventions for fetal disorders.

Primary disorders of water balance (central diabetes insipidus, congenital nephrogenic diabetes insipidus, and psychogenic polydipsia) should always be considered in the differential diagnosis of polyuria and polydipsia. In general, animals with these disorders have only one laboratory abnormality, a low urine specific gravity. The more common causes of polyuria and polydipsia (eg, hypercalcemia, chronic renal insufficiency, pyelonephritis, hyperadrenocorticism), in most instances, have specific and obvious abnormalities associated with the complete blood count (CBC), serum chemistry profile, and urinalysis. However, in some cases, a low urine specific gravity may initially be the only abnormality in these more common ruleouts. The workup for polyuria and polydipsia, especially in those cases with normal or near normal blood work, can be tedious, time consuming, confusing, and not without significant patient morbidity. This chapter will focus on the problems associated with diagnostic testing used to evaluate animals with disorders of water balance.

Studies using cultured cells have shown that gamma interferon (IFN-gamma) induces the expression of Fc gamma RI (the type I Fc receptor for IgG) on human polymorphonuclear neutrophils (PMN) and greatly increases the number of these receptors on human monocytes. Administration of rIFN-gamma in vivo also causes enhanced Fc gamma RI expression on these cell populations. Because streptococcal antigens are potent inducers of IFN-gamma in vitro, we postulated that IFN-gamma would be produced endogenously in vivo in patients with streptococcal infections. Such production of IFN-gamma in vivo, even at low levels, might be expected to induce the expression of Fc gamma RI on monocytes and neutrophils. To evaluate this possibility, we used monoclonal antibody 32 (mAb 32), which is specific for Fc gamma RI, to quantitate the expression of this receptor on human peripheral blood cells. We measured the binding of mAb 32 to monocytes and PMNs isolated from healthy donors and from patients with group A beta-hemolytic streptococcal (GABHS) pharyngitis. PMNs from healthy donors (n = 12) had 700 +/- 600 (mean +/- SD) mAb 32 binding sites. Patients with pharyngitis and negative throat culture for GABHS (n = 11) had 2,100 +/- 1,600 sites on their PMNs. In contrast, the PMNs from patients with documented GABHS pharyngitis (n = 12) had 11,600 +/- 7,500 mAb 32 binding sites on their surface. There was a similar change in the expression of Fc gamma RI on monocytes, with control monocytes having a mean of 19,900 +/- 3,200 mAb 32 binding sites per cell and the GABHS-positive monocytes having 47,500 +/- 21,400 sites. The GABHS-negative throat culture group had a slightly elevated number of Fc gamma RI with a mean of 28,200 +/- 8,400 sites. 10 patients with documented urinary tract infections and three patients with uncomplicated pyelonephritis had no elevation in Fc gamma RI expression. These studies demonstrate that a localized group A streptococcal infection can cause systemic activation of the entire circulating pool of phagocytes, and suggest that a similar level of activation is uncommon in localized gram-negative infections of the urinary tract.

Emphysematous pyelonephritis in patients with diabetes mellitus is increasingly recognised as a disease requiring urgent and aggressive treatment. We present 3 cases of emphysematous pyelonephritis; 1 patient required percutaneous nephrostomy followed by nephroureterectomy but the other 2 were successfully managed with antibiotics and control of diabetes. Diagnosis was confirmed by sequential imaging techniques which demonstrated an inflammatory renal mass associated with gas and fluid.

Escherichia coli (E. coli) causes greater than 90% of urinary tract infections, UTI, in childhood. The capacity to adhere to urinary tract epithelial cells characterizes E. coli strains that cause acute pyelonephritis. Adherence of uropathogenic E. coli is the result of a specific interaction between bacterial adhesins and glycolipid receptors on the host cells, especially the globoseries of glycolipids which share the Galactose alpha 1-greater than 4Galactose beta disaccharide (Gal alpha 1-greater than 4Gal beta). In childhood UTI, Gal alpha 1-greater than 4Gal beta-binding bacteria caused significantly higher body temperature, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and pyuria, and lower renal concentrating capacity, than E. coli lacking this specificity. The Gal alpha 1-greater than 4Gal beta-binding bacteria thus appeared to be more potent inducers of inflammation than other strains. Since inflammation may lead to tissue damage we examined the relationship of infection with Gal alpha 1-greater than 4Gal beta-positive bacteria to renal scarring. The frequency of renal scarring was 5% in boys with Gal alpha 1-greater than 4Gal beta-positive and 40% in boys with Gal alpha 1-greater than 4Gal beta-negative E. coli. Bacterial binding to Gal alpha 1-greater than 4Gal beta can be detected with a commercially available test reagent. This reagent can thus be used as an effective predictor of risk for renal scarring. Interleukin-6 (IL-6) is a pyrogen and inducer of the acute phase reactants. It was shown to be produced locally in the urinary tract, in response to UTI, and to spread systemically. Mucosal challenge with dead bacteria was sufficient to induce the IL-6 response. Circulating IL-6, and/or IL-1 and tumor necrosis factor could explain the fever, as well as increased ESR and CRP found in association with acute symptomatic UTI.

Eight pediatric cases of the diffuse form of xanthogranulomatous pyelonephritis are reported. These patients were selected among 17 with destruction of one kidney. Clinical symptoms were suggestive of a tumor in some instances. However, an infectious etiology was strongly suggested by the presence of a renal lithiasis in seven cases (including five staghorn stones) and of a urinary tract infection in six cases (usually caused by a Proteus). Nephrectomy was performed in every case.
