Vasopressin response to osmotic stimulation in 18 young dogs with polyuria and polydipsia

Common disorders of water homeostasis leading to polyuria include a variety of endocrine, metabolic, and renal disturbances. After exclusion of most of these conditions, the diagnostic dilemma of differentiating between central diabetes insipidus, primary polydipsia, and nephrogenic diabetes insipidus may remain. Here, we report on 18 young dogs with polyuria that had been present in most cases since the dogs were puppies. The conditions were categorized according to the plasma vasopressin (VP) response to hypertonicity. The VP response to osmotic stimulation was tested by IV infusion of 20% NaCl for 2 hours. The VP response in all dogs was abnormal. Three categories could be distinguished: an exaggerated response (n = 3), a subnormal response (n = 4), and a nonlinear response with high plasma VP concentrations unrelated to increases in plasma osmolality (n = 11). The VP response to hypertonicity did not consistently distinguish among different clinical entities. In the 9 dogs with variations in urine osmolality compatible with primary polydipsia, exaggerated, subnormal, and nonlinear responses were observed. Examination of the present data questions the generally accepted notion that VP measurements during hypertonic saline infusion are the "gold standard" for the diagnostic interpretation of causes of polydipsia and polyuria. Studies of the peripheral reflection in plasma of the pulsatile VP release in healthy and polyuric individuals, with and without osmotic provocation, should be performed.  相似文献   

Configuration of antibodies for assay of urinary cortisol in dogs influences analytic specificity     

F.K. Zeugswetter  F. Neffe  I. Schwendenwein  A. Tichy  E. Möstl 《Domestic animal endocrinology》2013

Whether the variation in the reported urinary corticoid-to-creatinine ratio in dogs is affected by the application of 2 commonly applied anticortisol antibodies was investigated. Free-catch morning urine samples of 50 healthy dogs were analyzed in duplicate with the use of 2 different polyclonal antibodies (antibody A and B) raised in different rabbits. Antibody A was raised against cortisol-3-carboxymethyl-oxime and antibody B against cortisol-21-hemisuccinate linked to BSA. Enzyme immunoassays were applied by using corresponding biotinylated labels. To examine possible cross-reactions with conjugated and nonconjugated cortisol metabolites, EIA measurements were performed with urine samples both before (directly assayed) and after diethyl-ether extraction, as well as after reversed-phase HPLC. Although the results correlated (P < 0.001), urinary corticoid concentrations and accordingly the urinary corticoid-to-creatinine ratios were 8 times higher when using antibody A than when using antibody B (mean ± SD corticoid concentrations, 223 ± 131 vs 29 ± 12 nmol/L; P < 0.001). Irrespective of the antibody used, extraction significantly decreased measured corticoid concentrations (antibody A, 158 ± 120 nmol/L; antibody B, 15 ± 8 nmol/L; P < 0.001), but the decrease was conspicuous when antibody A was used. Antibody A cross-reacted significantly with polar (eg, conjugated) metabolites, clearly depicted in the chromatogram by 3 additional peaks in earlier fractions well separated from cortisol. In contrast the assay that used antibody B was specific, showing only 1 major peak in the fractions eluting authentic cortisol. In summary, the study indicates that the configuration of the antibody considerably influences the analytic specificity of cortisol assays and underlines the pivotal importance of assay validation for each species and sample material.  相似文献   

Successful outcome in a case of equine multinodular pulmonary fibrosis (EMPF) treated with valacyclovir     

B. Schwarz  I. Schwendenwein  R. van den Hoven 《Equine Veterinary Education》2013,25(8):389-392

Equine multinodular pulmonary fibrosis (EMPF) is a progressive fibrosing interstitial lung disease, which has been associated with γ‐herpesviruses. This report describes a 22‐year‐old Warmblood stallion diagnosed with EMPF on the basis of clinical examination, laboratory results, lung radiographs and ultrasound, lung biopsy and inclusion bodies found in macrophages of broncho‐alveolar lavage fluid (BALF) as well as an identification of EHV‐5 DNA by polymerase chain reaction (PCR). The horse recovered after one week of treatment with valacyclovir (40 mg/kg bwt per os q. 8 h) and is clinically healthy 2 years later. To our knowledge this is the first report describing treatment of EMPF with valacyclovir.  相似文献   

Effect of altrenogest‐treatment of mares in late gestation on adrenocortical function,blood count and plasma electrolytes in their foals     

S. Neuhauser  F. Palm  F. Ambuehl  E. Möstl  I. Schwendenwein  C. Aurich 《Equine veterinary journal》2009,41(6):572-577

Reasons for performing study: Mares with compromised pregnancies are often treated with altrenogest to prevent abortion. However, there is only limited information about effects on the foal when altrenogest treatment is continued during final maturation of the fetus. Objectives: To determine effects of altrenogest treatment during late gestation in mares on maturity, haematology changes, adrenocortical function and serum electrolytes in their newborn foals. Methods: Six mares were treated with altrenogest (0.088 mg/kg bwt) once daily from Day 280 of pregnancy until foaling and 7 mares served as controls. Results: Foals born to altrenogest‐treated mares had a significantly lower neutrophil/lymphocyte ratio on the first day after birth than control foals (P<0.05). Basal plasma cortisol concentrations immediately after birth were higher in foals of altrenogest‐treated mares than in control foals (P<0.05). Cortisol release in response to exogenous adrenocorticotropic hormone (ACTH) ‐ except for higher values 15 min after ACTH injection in foals of altrenogest‐treated mares on Day 1 ‐ revealed no differences in adrenocortical function between the groups of foals. Plasma potassium concentration in foals from altrenogest‐treated mares compared to control foals was significantly lower immediately after birth (P<0.05) and plasma ionised calcium concentration was significantly lower 3 h after birth (P = 0.01). Conclusions and potential relevance: Altrenogest treatment of pregnant mares prolonged labour had no major effects on adrenocortical function in foals. A reduced neutrophil/ lymphocyte ratio in these foals may suggest either immunomodulatory effects of altrenogest or dysmaturity of the foals.  相似文献   

Disturbed Vasopressin Release in 4 Dogs with So-Called Primary Polydipsia     

Ilse K. van  Vonderen  Hans S. Kooistra  Elpetra P.M. Sprang  Ad Rijnberk 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》1999,13(5):419-425

Primary polydipsia is characterized by a marked increase in water intake and secondary polyuria, and in dogs often is described as a behavioral problem or a psychological disorder. We describe 4 dogs with primary polydipsia, diagnosed on the basis of a modified water deprivation test, in which further examination included serial measurements of urine osmolality (UOsm) and plasma vasopressin (VP) measurements during water deprivation and hypertonic saline infusion. The dogs, ranging in age from 4 months to 4 years, all were presented for evaluation of polyuria and polydipsia. Physical examination, routine blood chemistry, and urinalysis disclosed no specific cause for the polyuria and polydipsia. During serial measurements UOsm spontaneously reached high concentrations in 2 dogs, whereas in the other 2 dogs UOsm also fluctuated but on no occasion exceeded 1,000 mosm/kg. Primary polydipsia was diagnosed when UOsm exceeded 1,000 mosm/kg at the end of the modified water deprivation test and plasma osmolality did not exceed the upper limit of the reference range during testing. During water deprivation, plasma VP concentrations remained relatively low. The VP response to hypertonic saline infusion was abnormal, with an increased threshold value in 3 dogs, an increased sensitivity in 2 dogs, and an exaggerated response in 1 dog. It is concluded that some dogs fulfilling current criteria for primary polydipsia produce concentrated urine spontaneously throughout the day in a pattern similar to what has been observed in healthy pet dogs. This finding can be regarded as diagnostic and precludes the need for a water deprivation test. During water deprivation testing, all 4 dogs produced highly concentrated urine in the face of low basal plasma VP concentrations. The observed abnormal VP release in response to hypertonic stimulation may be interpreted as a primary disturbance in the regulation of VP secretion, although it might also be the result of overhydration caused by a primary abnormality in drinking behavior.  相似文献   

Polyclonal antibody–based immunohistochemical detection of intraleukocytic Theileria parasites in roan and sable antelopes     

Sarah J. Clift  Bernat Martí-Garcia  Rephima M. Phaswane  Emily P. Mitchell  Antoinette I. Josemans  Ilse Vorster  Katja N. Koeppel  Jeanni Fehrsen 《Journal of veterinary diagnostic investigation》2021,33(6):1079

Theileria parasites commonly infect African wild artiodactyls. In rare roan (Hippotragus equinus) and sable (H. niger) antelopes, Theileria sp. (sable)-associated calf mortalities constrain breeding programs. The pathogenicity of most leukocyte-transforming Theileria spp. originates in their invasion of and multiplication in various mononuclear leukocytes, the transformation of both infected and uninfected leukocytes, and their infiltration of multiple organs. Understanding the pathogenesis of theileriosis can be improved by the use of immunohistochemistry (IHC) to identify the localization of the parasites in tissue sections. Our aim was to develop a reproducible IHC assay to detect leukocyte-associated Theileria parasites in formalin-fixed, paraffin-embedded roan and sable tissues. Polyclonal antibodies were purified from the sera of 5 roans from an area endemic for Theileria sp. (sable) and tested for IHC reactivity in 55 infected and 39 control roan and sable antelopes, and for antigen and species cross-reactivity in an additional 58 cases. The 3 strongest antibodies consistently detected intraleukocytic theilerial antigens in known positive cases in roan and sable antelopes, and also detected other Theileria spp. in non-hippotraginid wild artiodactyl tissues. The antibodies did not cross-react with other apicomplexan protozoa, with the exception of Cryptosporidium. Given that PCR on its own cannot determine the significance of theilerial infection in wild ruminants, IHC is a useful laboratory test with which to confirm the diagnosis in these species.  相似文献
