SCHWARTZ-BARTTER SYNDROME (SIADH) IN DOGS AND CATS – AN ENDOCRINE DISORDER RARELY DIAGNOSED IN VETERINARY PRACTICE.
Schwartz-Bartter syndrome also known as syndrome of inappropriate antidiuretic hormone secretion (SIADH) or syndrome of inappropriate antidiuresis (SIAD) is an endocrine disorder of sodium and water balance caused by inappropriate secretion of antidiuretic hormone (arginine vasopressin). Rarely this syndrome may be also caused by genetic mutation which leads to permanent activation of vasopressin receptors in kidneys. In human medicine SIADH is considered as one of the main causes of plasma hypoosmolality in hospitalized patients. Although many reports of SIAD in human medicine, only 18 cases were reported in dogs and cats (15 in dogs and 3 in cats). The purpose of this review article (divided into two parts) was to present to Polish veterinary practitioners currently known mechanisms of action of antidiuretic hormone, causes and types of SIAD, pathogenesis of SIAD, the course of SIADH in dogs and cats, diagnosis of this disorder, and treatment of hyponatremia with emphasized risk of osmotic myelinolisis development as a result of the therapy.
Hyperaldosteronism in canine babesiosis. Życie Weterynaryjne, 2019, 94(2), 134-141. [IN POLISH]
Gójska-Zygner O., Zygner W.
In dogs and cats overproduction of aldosterone (mineralocorticoid homone) leads to hyperaldosteronism which may be primary or secondary. In primary hyperaldosteronism increased secretion of aldosterone results from independent production of the hormone by active tumor of the adrenal gland. In secondary hyperaldosteronism increased production and secretion of aldosterone results from stimulation of renin-angiotensin-aldosterone system by stimuli such as hypotension, hyponatremia and decreased renal perfusion. In canine babesiosis all these stimuli were observed and in 2015 the authors of this article detected secondary hyperaldosteronism in dogs infected with Babesia canis (results published in Veterinary Quarterly, doi: 10.1080/01652176.2014.981765 [LINK]. In this review article physiology of the renin-angiotensin-aldosterone system is presented, and probable mechanism of the development of secondary hyperaldosteronism in canine babesiosis is proposed.
Polybrominated diphenyl ethers in feline hyperthyroidism. Życie Weterynaryjne, 2019, 94(1), 29-33. [IN POLISH]
Polybrominated diphenyl ethers (PBDEs) are used in industry as fire retardants in the production of electrical and electronic equipment, plastic items, furniture etc. Many studies showed increased concentration of PBDEs in human and animal tissues. It seems probable that PBDEs contribute in feline hyperthyroidism development. Associations between risk factors of feline hyperthyroidism and PBDEs were discussed in this review article.
Over 20 years of research on canine babesiosis in Faculty of Veterinary Medicine WULS-SGGW in Warsaw. Medycyna Weterynaryjna, 2017, 73(10), 606-612. [IN POLISH]

The first case of canine babesiosis (protozoan disease caused by the infection with the parasite of the genus Babesia) in Poland was detected in Lublin in July 1964, and the case report was published in 1966 in the journal "Medycyna Weterynaryjna" by Pinkiewicz E. and Grzebuła S. [LINK], veterinarians from the Faculty of Veterinary Medicine in Lublin. However, the first two cases of the infection in Warsaw was detected in 1994 (published in 1995) by Hułas C. and Dobrzyński A. [LINK], veterinarians from the Faculty of Veterinary Medicine in Warsaw. Since that time many studies on the occurrence, prevalence, diagnostics, and pathogenesis of canine babesiosis were published by veterinarians and researchers from Poland. Scientists and veterinarians from the Faculty of Veterinary Medicine in Warsaw contributed in many of those works. Over 20 years of studies on canine babesiosis in Warsaw are discussed in this review work.
Feline acromegaly from the perspective of the Polish veterinary practitioner. Weterynaria po Dyplomie, 2014, 15(4), 14-15. [IN POLISH]
The article is commentary on two review articles of Wakayama J. and Bruyette D.S. about diagnosis and treatment of feline acromegaly which were published in Polish translation in "Weterynaria po Dyplomie". It presents choices and costs of the diagnosis and treatment of feline acromegaly in Poland.
Cutaneous paraneoplastic syndrome in cats with thymoma. Życie Weterynaryjne, 2014, 89(3), 204-207. [in Polish]
Gójska-Zygner O. , Karaś-Tęcza J., Rodo A.
Thymoma (a tumor developing from epithelial cells of the thymus) is a rare neoplastic disease in cats, which leads to the development of skin disease as a paraneoplastic syndrome (pathological changes associated with a neoplastic disease but distant from the tumor). According to the authors’ knowledge there were no previous reviews in the Polish veterinary literature about feline thymoma and subsequent dermatological signs caused by this tumor. Pathogenesis, diagnosis and treatment of cats with thymoma and cutaneous paraneoplastic syndrome is presented in this article.

Canine Conn’s syndrome (primary hyperaldosteronism) is a rare endocrine disorder in dogs that is not well known to many veterinary practitioners, and according to the authors knowledge there were no articles about this disease in the Polish veterinary literature except for one case report (Gójska-Zygner and Marciński 2013) published in Weterynaria w Praktyce (the article presented on this website in the Case Report bookmark). The lack of a review article about Conn’s syndrome in dogs in the Polish veterinary literature represented a significant gap, especially because of the fact that the first description of presumptive primary hyperaldosteronism (two cases of men with hypertension, renal insufficiency, and adrenal tumors, with proliferation of cells resembling those from zona glomerulosa observed in microscopic examination) was presented in the year 1953 (two years before Dr. Jerome W. Conn) in Polski Tygodnik Lekarski by Polish internist Dr. Michał Lityński. Therefore, the authors of the presented review article about canine primary hyperaldosteronism considered there was a need for such a publication in the Polish veterinary literature, and of course Dr. Michał Lityński is also mentioned in this work.
