Potencial da ozonioterapia como adjunto no tratamento de púrpura hemorrágica equina

Abstract

Hemorrhagic purpura in horses is an acute and non-contagious disease resulting from an immune-mediated hypersensitivity reaction characterized by generalized vasculitis, generally caused by a complication of equine infection.Streptococcus equi (S. equi) subspecies equi (subsp. equi). The disease is characterized by generalized edema in the subcutaneous tissue, the presence of hemorrhages in the mucous membranes and fistulas in the extremities. The diagnosis is made based on clinical signs, anamnesis and complementary exams, such as blood count, biochemistry, skin biopsy and isolation of the agent. The objective of this work is to report the use of ozone therapy as an adjuvant therapy in the treatment of hemorrhagic purpura in horses. A 6-year-old female horse, Quarter Horse, with a history of equine adenitis treated with a underdose of antibiotics, had presented apathy, dyspnea, limb edema, petechial hemorrhages in the ocular and vaginal mucosa and fistulas in all four limbs for 15 days. Allopathic therapy associated with ozone therapy by rectal insufflation and minor autohemotherapy at VG1 points and immunity points was instituted. After 30 days of treatment, the animal showed regression of clinical signs and complete recovery. The combination of therapies was effective in the treatment of hemorrhagic purpura in horses, but more studies must be carried out in order to standardize ozone therapy protocols and minor autohemotherapy in the treatment of conditions in horses.
