T1  - Relationship between urinary Tamm-Horsfall protein excretion and renal function in dogs with naturally occurring renal disease
JF  - Veterinary clinical pathology
N2  - Background Tamm-Horsfall protein (THP) is physiologically excreted in urine, but little is known about the role of THP in the diagnosis of renal disease in dogs. Objective The aim of this study was to evaluate to which extent naturally occurring renal disease affects the urinary excretion of THP. Methods Dogs were divided into 5 groups according to plasma creatinine concentration, urinary protein-to-creatinine ratio (UP/UC), and exogenous plasma creatinine clearance (P-ClCr) rates: Group A (healthy control dogs; n=8), nonazotemic and nonproteinuric dogs, with P-ClCr rates > 90mL/min/m2; group B (n=25), nonazotemic and nonproteinuric dogs with reduced P-ClCr rates (51-89mL/min/m2); group C (n=7), nonazotemic but proteinuric dogs with P-ClCr rates 53-98mL/min/m2; group D (n=8), azotemic and borderline proteinuric dogs (P-ClCr rates: 22-45mL/min/m2); and group E (n=15), azotemic and proteinuric dogs (not tested for P-ClCr). THP was measured by quantitative Western blot analysis, and the ratio of THP-to-urinary creatinine (THP/UC) was calculated. Results The THP/UC concentrations were not different among dogs of groups A-D, but were reduced in dogs of group E (P<.001). THP/UC correlated negatively with serum creatinine (P<.01) and UP/UC (P<.01), but was not significantly associated with P-ClCr. Conclusions Decreased levels of THP/UC were present in moderately to severely azotemic and proteinuric dogs. This suggests tubular injury in these dogs and that THP might be useful as urinary marker to study the pathogenesis of renal disease.

T1  - Calcitriol induced hypercalcemia in a hunting dog with a disseminated Paecilomyces variotii infection
T1  - Calcitriol-bedingte Hyperkalzämie bei einem Jagdhund mit disseminierter Paecilomyces variotii-Infektion

N2  - A 5-year old hunting dog was presented with reduced appetite, weight loss and polyuria/polydipsia. Hematology and clinical chemistry revealed anemia, leukocytosis, increased liver enzymes, hypoalbuminemia and hypercalcemia. The cytological, pathohistological and microbiological examination identified a disseminated infection with the saprophytic mould fungus Paecilomyces variotii in the biopsies of the spleen and a lymph node. Determination of vitamin D metabolites confirmed a calcitriol induced hypercalcemia.
N2  - Ein 5-jähriger Jagdhund wurde wegen verminderter Futteraufnahme, Gewichtsverlust und Polyurie/Polydipsie vorgestellt. In der hämatologischen und klinisch-chemischen Blutuntersuchung wurde neben einer Anämie und Leukozytose eine Erhöhung der Leberenzyme, Hypoalbuminämie und Hyperkalzämie festgestellt. Durch zytologische, pathohistologische und mikrobiologische Untersuchungen von Biopsien aus Milz und Lymphknoten konnte eine systemische Schimmelpilzinfektion mit Paecilomyces variotii nachgewiesen werden. Die Bestimmung der Vitamin-D-Metabolite bestätigte das Vorliegen einer Hyperkalzämie infolge einer Erhöhung der Calcitriolkonzentration.
