“…The successful use of triamcinolone acetonide has previously been reported in the treatment of equine cutaneous pythiosis (Cuero-Castilla & Mendoza-Espinoza 1985apud Mendoza et al 1996, Cardona-Álvarez et al 2016. Our experience with only one horse in the final phase of the disease confirmed these results.…”

“…Our experience with only one horse in the final phase of the disease confirmed these results. As surgical removal would be ineffective and pythiosis vaccines have not yet been approved in Uruguay, we decided to administer 50 mg IM triamcinolone acetonide biweekly, as previously recommended (Cardona-Álvarez et al 2016).…”

“…Some authors point to the high efficacy of the use of amphotericin B in a 10% solution of dimethylsulfoxide by means of the intravenous distal regional perfusion technique (Dória et al 2015). An earlier report of several horses cured following the use of the synthetic corticosteroid triamcinolone acetonide intramuscularly (Cuero-Castilla & Mendoza-Espinoza 1985apud Mendoza et al 1996 was recently confirmed in a case-control study with 100% efficacy in 12 affected horses (Cardona-Álvarez et al 2016(Cardona-Álvarez et al , 2017.…”

Equine pythiosis is an ulcerative and granulomatous disease of the skin, caused by the oomycete Pythium insidiosum (Pythiaceae). The objective of this study was to describe seven cases of equine pythiosis that occurred from 2012 to 2017 in the eastern region of Uruguay. Six of the seven cases occurred in the eastern wetland ecosystems of the Merin basin, and the remaining case occurred in the wetland fluvial plains of the Tacuarembó River. Lesions consisted of a large, rapidly growing ulcerated tumor with abundant granulation tissue, serosanguineous secretion, and fistulous tracts containing large concretions or kunkers. The animals presented intense pruritus, claudication and loss of body condition, with death or euthanasia in extremis in six cases. The main histological lesions consisted of an eosinophilic and pyogranulomatous inflammatory process, with numerous foci of eosinophilic necrosis (kunkers), collagenolysis, and a Splendore-Hoeppli reaction. In all cases, silver coloration (Grocott) showed intralesional hyphae compatible with P. insidiosum, which was confirmed by immunohistochemistry in three cases. A horse in the terminal phase of the disease was treated with triamcinolone acetonide (50mg IM every 15 days), and fully recovered after 1 year. It is concluded that equine pythiosis is prevalent in the wetland ecosystems of eastern Uruguay and that treatment with triamcinolone is auspicious.

“…Surgical excision is the most commonly applied therapy and is preferably combined with drugs such as potassium iodide or antifungal agents such as amphotericin B (DÓRIA et al, 2012(DÓRIA et al, , 2015CARVALHO et al, 2016). We also found reports of therapeutic success with 'Pitium-Vac' immunotherapy (SAMPAIO et al, 2016) and application of corticosteroid triamcinolone acetonide (CARDONA-ÁLVAREZ et al, 2016).…”

Cutaneous pythiosis is an important disease affecting horses raised in regions with a hot climate and water stagnation, occurring throughout all regions of Brazil. The disease progresses rapidly, and treatment for chronic lesions is challenging. The purpose of this study was to evaluate the efficacy of fluconazole after surgical excision and electrocauterization of cutaneous lesions in horses naturally infected with Pythium insidiosum. We treated 10 horses with cutaneous pythiosis, whose diagnoses were confirmed by histopathological and immunohistochemical examinations. After surgical debridement of lesion, animals received fluconazole orally for 21 days, in combination with topical treatment for the wounds. After 7 days of therapy, there was decreased serosanguineous secretion and no kunkers in the wounds in all horses. All lesions healed completely after therapy, and there were no recurrences 10 months after discharge. When associated with surgical excision, oral fluconazole therapy was an effective treatment in clinical cases of equine cutaneous pythiosis.

Se reporta un caso de una yegua criolla colombiana, color castaño, de 7 años y un peso de 300 Kg, la cual fue atendida por el Servicio Clínico Ambulatorio del área de Clínica Médico-Quirúrgica de Grandes Animales de la Universidad de Córdoba. La anamnesis indica que la yegua presentó un aumento progresivo de tamaño a nivel de la glándula mamaria, con secreción mucopurulenta constante por diferentes orificios, así mismo el propietario reporta que le realizó incisiones para facilitar el drenaje de material desde la glándula mamaría, ya que pensaba que ese aumento consistía en un absceso, de igual forma, informó la aplicación de antibióticos a base de tetraciclinas y antiinflamatorios no esteroidales. Al examen clínico, se determinó la presencia de una lesión granulomatosa que comprometía toda la glándula mamaria, con presencia de varias aberturas en forma de cráter y salida de material fibrinopurulento, a la compresión presento salida de mayor cantidad de secreción, así como masas caseificadas llamadas Kunker. Se decidió realizar mastectomía total como medida de control y alargar la vida útil de la yegua. Durante el procedimiento quirúrgico bajo anestesia general, se evidenció la presencia de abundante tejido granulomatoso, así como la presencia de grandes cantidades de kunkers acumulados en cavitaciones originadas por la invasión del Pythium insidiosum en el tejido granular. Se concluye la importancia de conocer la epidemiología de la Pythiosis, siendo relevante la ubicación de casos clínicos a nivel de glándula mamaria en yeguas criollas colombianas expuestas a factores de riesgo.
