- The aim of this study was to assess clinical signs and altered pulmonary cell expression of cytokines related to eosinophil kinetics in horses with pulmonary eosinophilia. Pulmonary eosinophilia was detected by bronchoalveolar lavage (BAL) in a group of standardbreds in training. Horses had detailed clinical examination, bronchoscopy, endobronchial biopsy and BAL on three occasions at approximately 6 month intervals. During the second sampling period BAL eosinophils were significantly elevated (p > ; 0.010), with five horses having from 5% to 37% eosinophils in BAL. Neither detailed clinical examination parameters nor gene expression of IL-4 and IL-5 mRNA (real-time-PCR) were associated with BAL eosinophilia. Pulmonary eosinophilia abated without treatment apart from deworming. It appears that pronounced lung eosinophilia in horses can be transient, abate without specific treatment, and in this instance, lack correlation to upregulation of expression of either IL-4 or IL-5.

- BACKGROUND: Biological variation (BV) of urinary (U) biochemical analytes has not been described in absolute terms, let alone as a ratio of the U-creatinine or fractional excretion in healthy dogs. These analytes are potential diagnostic tools for different types of kidney damage and electrolyte disorders in dogs.OBJECTIVES: We aimed to investigate the BV of specific gravity, osmolality, creatinine, urea, protein, glucose, chloride, sodium, potassium, calcium, and phosphate in urine from healthy pet dogs.METHODS: Blood and urine samples from 13 dogs were collected once weekly for 8 weeks. Samples were analyzed in duplicate and in randomized order. For each sample, U-analyte and serum concentrations were measured, and U-analyte/U-creatinine and fractional excretion (FE) were calculated. Components of variance, estimated by restricted maximum likelihood, were used to determine within-subject variation (CVI ), between-subject variation (CVG ), and analytical variation (CVA ). Index of individuality (II) and reference change values were calculated.RESULTS: CVI for all urine analytes varied between 12.6% and 35.9%, except for U-sodium, U-sodium/U-Cr, and FE-sodium, which had higher CVI s (59.5%-60.7%). For U-protein, U-sodium, U-potassium, U-sodium/U-creatinine, FE-urea, FE-glucose, FE-sodium, FE-potassium, and FE-phosphate II were low, indicating that population-based RIs were appropriate. The remaining analytes had an intermediate II, suggesting that population-based RIs should be used with caution.CONCLUSION: This study presents information on the biological variation of urinary and serum biochemical analytes from healthy dogs. These data are important for an appropriate interpretation of laboratory results.

- Background In the dog, the normal estrous cycle includes a prolonged luteal phase. Progesterone stimulates local canine mammary growth hormone (GH) production, which may act systemically and contribute to insulin resistance. Swedish Elkhounds are predisposed to progesterone-related diabetes mellitus, and the relationship among insulin resistance, GH, and insulin-like growth factor I (IGF-I) is of particular interest. Objective To study insulin resistance in relation to GH and IGF-I in nondiabetic Swedish Elkhounds during diestrus. We also assessed whether alterations in these hormones could predict diestrus-linked diseases and all-cause mortality. Animals Eighty-four privately owned female intact Swedish Elkhounds >4years of age. Methods Blood sampling and clinical examination during luteal phase, with a follow-up questionnaire after 20months. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Results In multivariable regression analysis, GH was positively associated with HOMA-IR (P=.009). An increase in GH of 1ng/mL was associated with a 12.7% increase in HOMA-IR. Moreover, C-peptide was positively associated with IGF-I (P=.04), and an increase in C-peptide of 0.1ng/mL was associated with a 6.9% increase in IGF-I. Structural equation modeling supported these results. Twenty-three animals were found to have previously unrecognized mammary masses and had higher GH (P<.0001) and IGF-I (P=.007) than dogs without mammary masses (n=61). There was no association between high GH and IGF-I concentrations at sampling and future mammary masses. Conclusion We showed that GH was strongly associated with insulin resistance in older Swedish Elkhounds during diestrus.
