Prednisolone associated with doxycycline on the hematological parameters and serum proteinogram of dogs with ehrlichiosis / Efeitos da influência da prednisolona associada à doxiciclina nos parâmetros hematológicos e proteinograma sérico de cães com erliquiose

The objective of the present study was to assess the treatment of dogs with ehrlichiosis (tropical canine pancytopenia (TCP)) with doxycycline hydrochloride associated or not with prednisolone on the hematological profile and serum proteins. Ten dogs with TCP were selected in the Small Animal Medical Clinic Veterinary Hospital, Federal University of Campina Grande-UFCG-PB, Brazil. The diagnosis was obtained by clinical examination, hemogram and immunochromatographic test (with anti Ehrlichia canis antibodies). Samples were distributed randomly in two experimental groups of five animals each (n = 5), named GD and GDP. The GD group was treated with doxycycline (5 mg/kg, VO, BID for 28 days) and the GDP group was treated with doxycycline at the same dose and duration and prednisolone (2 mg/kg, VO, BID, for five days). Four blood collections were made during the treatment period: a base collection (M0), one at 10 days (M10), a second at 21 days (M21) and another at the end of the treatment (M28). These samples were used for the tests erythrogram, leucogram, plateletgram and proteinogram (dose of total proteins, pre-albumin, albumin, albumin, -1 globulin, -2 globulin, ß-globulin, -globulin and C- reactive protein) in the Clinical Pathology Laboratory, Veterinary Hospital-UFCG-PB. Results, that presented normal distribution, was submitted to the Tukey test (P 0.05). Comparison of treatments GD and GDP showed that both promoted discreet and similar response in the hematological parameters at different times. Results obtained allowed the conclusion that both therapeutic protocols resulted in clinical, hematological parameter and proteinogram improvement, but the use of prednisolone at the dose administered during the first five days of treatment did not show more beneficial effects than isolated administration of doxycycline.(AU)

Objetivou-se com este estudo avaliar os efeitos do tratamento de cães com erliquiose monocítica canina (EMC) com cloridrato de doxiciclina associada ou não à prednisolona sobre o perfil hematológico e de proteínas séricas. Foram selecionados, na Clínica Médica de Pequenos Animais do Hospital Veterinário da Universidade Federal de Campina Grande (UFCG), 10 cães com EMC. O diagnóstico foi obtido através de exame clínico, hemograma e teste de imunoensaio imunocromatográfico (com anticorpos anti Ehrlichia canis). As amostras foram distribuídas aleatoriamente em dois grupos experimentais, com cinco animais cada (n=5), denominados GD e GDP. O grupo GD foi tratado com doxiciclina (5 mg/kg, VO, BID durante 28 dias) e o grupo GDP, tratado com doxiciclina na mesma dose e duração e prednisolona (2 mg/kg, VO, BID, durante 5 dias). Durante o período de tratamento, foram realizadas quatro coletas de sangue; uma coleta basal (M0), uma com 10 dias (M10), uma aos 21 dias (M21) e outra ao final do tratamento (M28). Dessas amostras foram realizados eritrograma, leucograma, plaquetograma e proteinograma (dosagem de proteínas totais, pré-albumina, albumina, -1 globulina, -2 globulina, ß-globulina, -globulina e proteína C-reativa) no Laboratório de Patologia Clínica do Hospital Veterinário da UFCG. Os resultados que apresentaram distribuição normal foram submetidos ao teste de Tukey (P 0,05). Ao comparar os tratamentos GD e GDP, observou-se que os dois promoveram resposta discreta e semelhante dos parâmetros hematológicos nos diferentes momentos. Os resultados obtidos permitem concluir que ambos os protocolos terapêuticos resultaram em melhora clínica e dos parâmetros hematológicos e do proteinograma. Porém, o uso da prednisolona na dose empregada durante os primeiros cinco dias de tratamento não demonstrou efeitos mais benéficos do que a administração isolada da doxiciclina.(AU)

Reação imunológica decorrente a transfusão de concentrado de plaquetas em cão / Immunological reaction due to transfusion of platelet concentrate in dog

A transfusão de hemocomponente na medicina veterinária vem aumentando nos últimos anos, com isso aumenta-se também o potencial de reações transfusionais, que eventualmente podem ser fatais. Neste estudo, um cão de 3 meses de idade, fêmea, Sem Raça Definida com diagnóstico de hemoparasitose, realizado a partir de hemograma (anemia regenerativa com visualização de mórula de Ehrlichia canis em leucócitos e trombocitopenia de 80 mil plaquetas/dL) e ultrassonografia (hepatoesplenomegalia), foi encaminhado ao banco de sangue para ser submetido a transfusão de concentrado de plaquetas (CP), visto que apresentava petéquias, sufusões abdominais e havia sofrido alguns episódios de epistaxe. Após exame físico da paciente que se apresentava com parâmetros normais para a espécie, iniciou-se a transfusão do CP pela veia cefálica. Aos 30 minutos do início do procedimento documentou-se sialorréia intensa e eritema cutânea. A transfusão foi interrompida. Aplicou-se 0,5 mg/Kg de dexametasona por via intravenosa, 0,044 mg/Kg de atropina e 0,2 mg/Kg de prometazina ambos por via subcutânea, e em 40 minutos ocorreu normalização dos parâmetros clínicos. A transfusão de concentrado de plaquetas é um procedimento terapêutico e profilático importante no tratamento e prevenção de hemorragias, quando por deficiência numérica ou qualitativa das plaquetas. No entanto, riscos inerentes ao processo devem ser considerados, e expostos ao tutor. Contudo, descrevemos neste relato reação adversa em cão jovem (hipersensibilidade tipo 1) revertida com o uso imediato de corticosteróide associado a um antagonista colinérgico e anti-histaminico.(AU)

The transfusion of blood components in veterinary medicine has been increasing in recent years, thereby increasing the potential for transfusion reactions, which can eventually be fatal. In this study, a 3-month-old, female, Non-Breed dog diagnosed with hemoparasitosis, carried out using a complete blood count (regenerative anemia with visualization of Ehrlichia canis morula in leukocytes and thrombocytopenia of 80 thousand platelets/dL) and ultrasonography (hepatosplenomegaly), was referred to the blood bank to undergo a transfusion of platelet concentrate (PC), since she had petechiae, abdominal suffusions and had suffered some episodes of epistaxis. After physical examination of the patient who presented with normal parameters for the species, began the transfusion of PC through the cephalic vein. At 30 minutes from the beginning of the procedure, intense sialorrhea and skin erythema were documented. The transfusion was stopped, and 0.5 mg / kg of dexamethasone was applied intravenously, 0.044 mg / kg of atropine and 0.2 mg / kg of promethazine both subcutaneously. 40 minutes latter occurred normalization of clinical parameters. Platelet concentrate transfusion is an important therapeutic and prophylactic procedure in the treatment and prevention of bleeding, when due to numerical or qualitative platelet deficiency. However, risks inherent to the process must be considered, and exposed to the tutor. In this report, we describe an adverse reaction in a young dog (type 1 hypersensitivity) reversed with the immediate use of corticosteroids associated with a cholinergic and antihistamine antagonist.(AU)

Achados hematológicos em sangue e medula óssea de cães naturalmente infectados por Ehrlichia spp. e Anaplasma spp. / Hematological observations in the blood and bone marrow of dogs naturally infected by Ehrlichia spp. and Anaplasma spp.

Objetivou-se analisar os achados hematológicos em sangue periférico e medula óssea em cães infectados por Ehrlichia spp. e Anaplasma spp.. Avaliaram-se 44 cães com suspeita clínica de hemoparasitose, de diferentes raças, idades e de ambos os sexos, submetidos ao exame sorológico pelo SNAP Test, a análises hematológicas e mielograma. Dos 44 cães avaliados, 63,6% (28/44) foram sorologicamente reagentes, sendo 57,1% (16/28) positivos para Ehrlichia spp., 21,4% (6/28) para Anaplasma spp. e 21,4% (6/28) de coinfectados. A trombocitopenia foi a alteração hematológica mais frequente em cães positivos para Ehrlichia spp., presente em 93,7% (15/16) (p=0,015) dos animais, enquanto a anemia macrocítica e hipocrômica prevaleceu em 66,7% (4/6) (p=0,010) dos animais infectados por Anaplasma spp.. Ao mielograma, 62,5% (10/16) (p=0,005) dos animais positivos para Ehrlichia spp. apresentaram hipoplasia medular e 75,0% (12/16) (p=0,044) diminuição do índice mieloide:eritroide (M:E). Nos animais positivos para Anaplasma spp., destacou-se a hiperplasia da série eritroide em 50,0% (3/6) (p=0,022) dos cães. Não houve associação significativa em nenhuma das análises com o grupo coinfecção (p>0,05). Os resultados obtidos neste estudo permitem inferir que o somatório de métodos laboratoriais é essencial na caracterização das hemoparasitoses em cães, agregando valor e permitindo uma efetiva consolidação do diagnóstico relacionado a essas doenças.(AU)

This study aimed to analyze the hematological and cytomorphological findings in the peripheral blood and bone marrow of dogs infected with Ehrlichia spp. and Anaplasma spp. Forty-four dogs with clinically suspected hemoparasitosis, belonging to different breeds, ages, and both sexes, underwent serological examination by SNAP Assay, hematological analysis, and myelogram. Among them, 63.6% (28/44) tested serologically positive; among the serologically positive dogs, 57.1% (16/28) tested positive for Ehrlichia spp., 21.4% (6/28) for Anaplasma spp., and 21.4% (6/28) were coinfected. Thrombocytopenia was the most frequent hematologic alteration in dogs positive for Ehrlichia spp., present in 93.7% (15/16) (p=0.015) of the infected animals, while macrocytic and hypochromic anemia were observed in 66.7% (4/6) (p=0.010) of the animals infected with Anaplasma spp. In the myelogram, 62.5% (10/16, p=0.005) and 75.0% (12/16, p=0,044) of the animals positive for Ehrlichia spp. presented with bone marrow hypoplasia and decrease in the myeloid: erythroid (M:E) ratio, respectively. Hyperplasia of the erythroid series was observed in 50.0% (3/6) (p=0.022) of the animals positive for Anaplasma spp. No significant association was observed between the hematological alterations and the coinfection group (p >0.05). On the basis of these hematological observations, it can be inferred that the aforementioned laboratory examinations could be employed for the characterization and confirmative diagnosis of hemoparasitosis in dogs.(AU)

Serum biochemistry in dogs infected with Ehrlichia canis, Anaplasma platys and Leishmania sp / Bioquímica sérica de cães infectados por Ehrlichia canis, Anaplasma platys e Leishmania sp

Background: Hemoparasitoses have major importance in clinical diseases of small animals for infections are highly prevalent, easily transmitted and difficult to control. Clinical signs are nonspecific, but laboratory abnormalities are frequent, especially changes in serum biochemistry. In veterinary medicine, laboratorial findings may favor the diagnosis of hemoparasitoses and improve the quality of treatment given to these patients. The present study aimed at evaluating changes in serum biochemistry in dogs with molecular diagnosis of hemoparasites (Ehrlichia canis, Anaplasma platys and Leishmania sp.).Materials, Methods & Results: Molecular diagnosis for Ehrlichia canis, Anaplasma platys and Leishmania sp. were obtained in 26 dogs. A complete serum biochemical profile was determined in biochemical analyzer COBAS Mira. Biochemical analyzes, using commercial kits from Synermed, included total and partial protein by colorimetric method, creatinine by the kinetic method, urea, alanine aminotransferase (ALT), aspartate aminotrasnferase (AST), gamma glutamyl transferase (GGT) and alkaline phosphatase by enzymatic method. Considering reference values for canine species, it was observed an increase in the average value for serum urea concentration in dogs with leishmaniasis. These dogs also presented higher globulin concentration, while presenting reduction in serum albumin...(AU)
