Secreted by osteocytes and osteoblasts in response to hyperphosphatemia and increased plasma calcitriol concentrations.
acts in the kidney to inhibit calcitriol production by reducing mRNA expression of the vitamin D synthesis enzyme (25-hydroxyvitamin D-1a-hydroxylase) and to increase phosphaturia by down-regulating sodium-phosphorus type II co-transporters (NaPi-IIa and NaPi-IIc) in the proximal tubules.
Also acts in parathyroid gland to decrease PTH production and secretion.

Conclusion: Underlying pathophysiologic processes associated with PH instead of severeity of PH are likely responsible for increased RDW in dogs with PH
Palm 2016 Urinary Neutrophil Gelatinase-associated Lipocalin as a Marker for Identiﬁcation of Acute Kidney Injury and Recovery in Dogs with Gentamicin-induced Nephrotoxicity
Acute kidney injury was diagnosed signiﬁcantly earlier based on a 7-fold increase in UNCR (urine NGAL to creatinine ratio) compared to a > 50% increase in serum creatinine concentration
During recovery, the initial decrease in UNCR preceded the decrease in serum creatinine concentration by a median of 2 days.
Peters 2016: Cytological Findings of 140 Bile Samples from Dogs and Cats and Associated Clinical Pathological Data
Infectious agents in 30% canine samples and 22% feline samples
Inflammation in 5% of canine samples and 19% of feline samples.
Presence of microorganism more often detected on cytology than culture.
Most common isolates- e coli and enterococcus.
Only increased cPLI was significantly associated with presence of microorganisms, inflammatory cells or both in bile.
Piccione 2016: Tick-Borne Relapsing Fever in Dogs
What bugs cause it?
What tick transmits it?
What bloodwork finding is common?
How do you treat?
tick borne relapsing fever caused by borrelia turicatae and borrelia hermsii.
Transmitted by ornithodoros spp. ticks.
In the 5 dogs described, all had fevers and spirochetes seen in blood, all were thrombocytopenic.
Treat with tetracycline
Swann 2016 Demographic Characteristics, Survival and Prognostic Factors for Mortality in Cats with Primary Immune-Mediated Hemolytic Anemia
-sex, age or breed disposition?
- what were negative prognostic indicators?
- what were positive prognostic indicators?
No sex or breed predisposition was identiﬁed for the development of primary IMHA in comparison to the control cats, but cats in the age range 2.1–5.9 years were predisposed.
Higher total bilirubin concentration and age were signiﬁcant negative prognostic factors
higher lymphocyte numbers and serum globulin concentration were positive prognostic factors in a multivariable model.
Tamborini 2016 Bacterial Cholangitis, Cholecystitis, or both in Dogs
Most frequent isolates? Frequency of complications and association with mortality?
Most frequent isolates were e. coli, enterococcus and clostridium. High antimicrobial resistance.
Biliary tract rupture in 1/3 of cases, with 50% mortality rate.
Thomason 2016: The Effects of Cyclosporine and Aspirin on Platelet Function in Normal Dogs
Low-dose aspirin inhibits cyclosporine-induced thromboxane synthesis, and concurrent use of these medications does not alter the antiplatelet effects of aspirin.
Tjostheim 2016: Effects of Toceranib Phosphate on Systolic Blood Pressure and Proteinuria in Dogs
Systolic BP significantly higher in previously normotensive dogs afer initiation of treatment with toceranib phosphate compared to baseline. 37% of treated dogs developed SBP ≥ 160 mmHg.
Base-line prevelance of hypertension and proteinuria was not different from controls.
What is MOA of toceranib phosphate?
Tyrosine kinase inhibitor- inhibits the VEGF pathway. VEGF plays a key role in tumor neoangiogenesis.
White 2016: Subclinical Bacteriuria in Older Cats and its Association with Survival
The prevalence of SB varied between 10 and 13%, and incident infections were uncommon. Female cats were 21 times more likely to have a positive urine culture than were male cats
Williams 2016: Serum Cystatin C Concentrations in Cats with Hyperthyroidism and Chronic Kidney Disease
serum CysC not reliable in hyperthyroid cats.
SCysC in nonhyperthyroid cats with azotemic CKD and healthy older cats not significantly different.
