RESUMEN
BACKGROUND: Previous studies have documented vitamin D imbalance in dogs with acute pancreatitis (AP), but no studies have investigated serum vitamin D receptor (VDR) and vitamin D-binding protein (VDBP) concentrations. OBJECTIVES: Compare serum 25-hydroxyvitamin D (25[OH]D), VDR, and VDBP concentrations in healthy dogs and dogs with AP and identify correlations between these concentrations with ionized calcium, C-reactive protein (CRP), and canine-specific pancreatic lipase (Spec cPL) concentrations. ANIMALS: Twenty-two dogs with AP and 20 healthy control dogs. METHODS: Prospective cross-sectional study. Serum 25(OH)D concentrations were measured using a chemiluminescence immunoassay, and VDR and VDBP concentrations were measured using a ELISA kit designed for dogs. RESULTS: Serum concentrations of 25(OH)D were lower in dogs with AP (mean ± SD, 66.1 ± 39.2 ng/mL) than in controls (96.8 ± 30.4 ng/mL; P = .01), and VDR concentrations were lower in dogs with AP (5.3 ± 3.5 ng/mL) than in controls (7.4 ± 2.5 ng/mL; P = .03). No difference was observed in serum VDBP concentrations between the groups. Serum VDR concentrations differed between survivors (median [interquartile range] = 6.6 [4.3-8.2] ng/mL) and nonsurvivors (2.7 [0.5-3.5] ng/mL; P = .01). Negative correlations were observed among serum VDR, CRP (rs = -0.55), and Spec cPL (rs = -0.47) concentrations in dogs with AP. CONCLUSIONS AND CLINICAL IMPORTANCE: Dogs with AP had lower serum 25(OH)D and VDR concentrations than controls. Additionally, our study suggests a potential role of VDR expression in the inflammatory process of AP in dogs.

Pseudozyma species rarely cause invasive diseases in humans, which are usually isolated from plants. There have been anecdotal reports regarding Pseudozyma species infections in patients with underlying diseases or in neonates. However, clinical data and the pathogenicity in humans are still insufficient. We experienced a case of Pseudozyma aphidis fungaemia with invasive fungal pneumonia that developed during reinduction chemotherapy in a 51-year-old male with acute myeloid leukaemia (AML). P. aphidis was suspected based on the morphology of the yeast isolated from the blood and was confirmed via rDNA gene sequencing analysis. The patient successfully underwent stem cell transplantation with continuing antifungal treatment and finally completely recovered from both the AML and infectious complications. Here, we report a case of P. aphidis infection that developed during neutropenia in an AML patient and review the global literature.
