Abstract

The purpose of the study was to investigate the management of pyelonephritis in a large Italian pediatric population. A total of 1,333 patients (36% male) were considered. Escherichia coli was the most frequently isolated agent (89.9%), followed by Proteus mirabilis (3.6%) and Klebsiella oxytoca (2.1%). 27% of microorganisms were resistant to amoxicillin, 4% to amoxicillin/clavulanic acid, 11% to trimethoprim-sulfamethoxazole, 2.4% to gentamicin and less than 2% to ceftazidime. Despite this resistance pattern showing that oral antibiotics, such as amoxicillin/clavulanic acid, are effective in vitro as well as parenteral antimicrobials, a parenteral antibiotic was given initially to 756 (57.2%) children. A prophylactic regimen was started in 922 patients with a rate of reinfection during prophylaxis of 9.5%; a higher rate of reinfection was observed in patients with reflux (25%) compared to children without reflux (3%) (p < 0.0001). Vesicoureteral reflux was demonstrated in 30% of patients. The number of renal abnormalities detected by DMSA in patients with and without reflux was significantly different (p < 0.001). CRP was higher in patients with scars (p < 0.02). In conclusion, pyelonephritis represents a common disease with about 2,500 days of hospitalization per year in the Veneto Region where there is a pediatric population of about 800,000 under 15 years of age. The results of antimicrobial in vitro tests indicate that amoxillicin/clavulanic acid could represent the antibiotic of choice. The high frequency of malformations, observed even in children between 6 and 12 years of age, may suggest the need of an imaging study including DMSA scan and VCUG in all age groups.

Abstract

PAX2, a homeotic gene of ‘paired box family’, is a nuclear transcription factor expressed in mesenchymal/epithelial conversion during the early stages of nephrogenesis; however, its repression is necessary for terminal differentiation of mature tubular cells. Transgenic overexpression in animal model causes epithelial hyperproliferation and microcyst formation. In humans, PAX2 expression has been observed in cystic and dysplasic tubular epithelia in kidney malformation and in kidney disease. We have investigated PAX2 expression and its colocalization with cytokeratin and/or vimentin in 17 biopsies of juvenile nephronophthisis (NPH), an autosomal-recessive renal disease characterized by diffuse renal fibrosis and occasional cysts. Fourteen cases were analyzed for deletion and mutation in the NPH1 gene locus and 33% resulted to be deleted or mutated; for the remaining cases the diagnosis was based on clinical and pathological criteria. The control group included 4 congenital dysplastic kidneys, and 10 biopsies of nephropathies with secondary chronic tubulointerstitial damage. In all cases of renal dysplasia a strong nuclear positivity was observed in immature tubules surrounded by αSMA-positive mesenchymal cells. In NI biopsies the tubular epithelia were almost PAX2 negative, although tubulointerstitial damage was severe. In 14/17 NPH1 moderate-to-strong nuclear PAX2 positivity of tubular cells was observed, particularly in cystic distal tubules located at the corticomedullary junction, but also in proximal tubular sections. The PAX2 signal co-localized more with cytokeratin staining than with vimentin. Our results confirm the observation of PAX2 expression in immature dysplastic tubules and its repression in mature renal tubular cells, also in the presence of severe secondary interstitial fibrosis. PAX2 seems to be overexpressed in NPH. The genetic defect of NPH, a disease probably due to a primary defect along the cascade of mesenchymal epithelial differentiation, could generate a functionally abnormal protein involved in focal adhesion signaling and cell/matrix interaction. The failure of PAX2 repression or its reactivation in NPH could be a marker of hyperproliferation and incomplete maturation of epithelial tubular cells, probably due to a defect cell/matrix cross-talk, and involved in interstitial fibrosis and cysts formation.

Abstract

A nonradioactive in situ hybridization technique was utilized for the rapid and early diagnosis of cytomegalovirus (CMV) infection in children undergoing kidney transplantation. The cellular samples were obtained directly from the organs thought to be affected on the basis of clinical findings: bronchoalveolar lavage during interstitial pneumonia (7 samples from 6 cases); fine-needle aspiration biopsy (FNAB) of the liver during acute hepatitis (1 case); kidney FNAB and peripheral blood where there was a greater than or equal to 25% creatinine rise with or without fever (26 episodes). Standard virus isolation procedures and an immunofluorescent technique on short-term cultures of human fibroblast cells were performed as a control. 6/23 children followed had a symptomatic CMV infection (4 had interstitial pneumonia; 1 had acute hepatitis, and there was 1 case of creatinine rise with fever). In all cases, the diagnosis was provided by in situ hybridization in less than 24 h. These results were confirmed 48 h later by immunofluorescence and after 5-25 days by standard viral cultures. In situ hybridization with a biotinylated probe proved to be a rapid and sensitive method for diagnosis of CMV disease, when performed on specimens obtained from the involved organs at an early stage of the infection. This diagnostic approach allowed a specific antiviral therapy to be undertaken promptly.
