An 8-year-old castrated male Shih Tzu dog (weighing 7.0 kg) presented with anemia and lethargy. Initial diagnosis indicated immune-mediated hemolytic anemia. During therapy, a secondary urinary infection, probably due to the immune suppressive therapy, was diagnosed. Subsequent diagnostic tests, including urinalysis and urine culture, indicated candidal cystitis. Despite ketoconazole therapy for candidal cystitis, the dog died suddenly. A Candida albicans infection was confirmed upon postmortem evaluation. Prolonged immunosuppressive therapy might be the cause of this infection. This is the first case report describing a Candida albicans urinary tract infection accompanied by hemolytic anemia in a dog in Korea.

A 10-year-old spayed female Maltese presented with purpura and hematemesis. Initial laboratory evaluation revealed immune-mediated thrombocytopenia, but evidence of hemolytic anemia was not identified. Three milligrams of human intravenous immunoglobulin (hIVIG) was administered for 3 hours following prednisolone and mycophenolate mofetil. A pale mucous membrane was identified, and the packed cell volume decreased by 3%. Blood film examination revealed significant spherocytosis with auto-agglutination. Blood transfusions and immunosuppression were continued for 4 days, and hIVIG was discontinued. This report describes a case of increased immune-mediated hemolysis after hIVIG administration, possibly due to new-onset immune-mediated hemolytic anemia or enhanced immunogenicity.

A 3-year-old, 4.0 kg, intact male shih-tzu dog with anorexia, depression, pale mucous membranes, tachypnea, tachycardia was referred to the Veterinary Medical Teaching Hospital. Autoagglutination was observed by naked eye when blood was collected in an EDTA-tube and many spherocytes were found on a Diff-Quik stained blood smear. PCV was 6% and indirect bilirubin was increased markedly. So the immune-mediated hemolytic anemia was diagnosed. Autoagglutination was too severe to perform cross-matching test. Blood was not transfused as it might accelerate or precipitate hemolytic crisis, and regeneration of erythrocytes was very good. Thus corticosteroid of immunosuppressive dose and fluid were administered and PCV was monitored. Although blood was not transfused, PCV increased from 6 to 15.9% in a day and to 30% 7 days later. Therapy for liver was concurrently conducted because liver enzyme activities were high. Corticosteroid tappering therapy was conducted for 75 days and PCV was recovered to 46% after 4 months form start of the treatment.

A 5-year-old castrated male Shih-tzu dog and a 9-year-old intact female Schnauzer dog were presented with anorexia and depression. These 2 dogs were diagnosed based on which criteria as primary immune-mediated hemolytic anemia (IMHA). Blood examination showed anemia, spherocytosis, auto-agglutination and total bilirubinemia in 2 cases. These dogs were recovered by treatment of mycophenolate mofetil and prednisolone, and showed good prognosis until now. Mycophenolate mofetil is recommended as initial treatment in canine IMHA.

Three different dogs who had immune-mediated hemolytic anemia (IMHA) were treated for more than two weeks with blood transfusion in an animal clinic. Despite this treatment and hospitalization, there was no clinical improvement in clinical signs as well as complete blood cell count (CBC) including hematocrit (HCT) and C-reactive protein (CRP). All cases were then injected two or three times with allogeneic stem cells through an intravenous route for treatment. Upon administrating stem cells to the IMHA dogs, clinical conditions and the indexes of HCT and CRP were clinically improved within or close to normal ranges.

Immune-mediated hemolytic anemia (IMHA) is autoimmune disease which is anemia caused by own immune system destroying the red blood cells (RBC). It can be diagnosed with spherocytosis, positive auto-agglutination of RBCs and direct antiglobulin test (DAT, Coomb's test). The treatment for IMHA are blood transfusion, immunosuppressive agents including glucocorticoids and other supportive therapies. Danazol is synthetic androgen that has effect of interfering the autoimmune reaction to RBCs. It can be used as an adjunctive agent in addition to glucocorticoids. To investigate its effectiveness, the medical records of 10 IMHA-diagnosed dogs were evaluated. All subjects were treated with blood transfusion, prednisolone, mycophenolate mofetil, and intravenous human immunoglobulin G. Additionally, 6 subjects were administered with danazol and 4 subjects were not. The results of initial blood examination and responses to the treatment for IMHA were compared between the groups. There were significant differences in the number of blood transfusions; once in group with danazol, twice in group without danazol, duration of recovery to normal hematocrit; 7.67±3.08 days in group with danazol, 22.00±5.66 days in group without danazol, and hospitalization; 5.17±0.75 days in group with danazol, 12.75±2.22 days in group without danazol. Therefore, danazol has potential effective on treating IMHA for rapid improvement.

A 3-year-old spayed female Persian feline with non regenerative anemia showed persistent autoagglutination in EDTA anticoagulated blood. Primary immune-mediated hemolytic anemia (IMHA) was suspected and the underlying causes for IMHA were excluded by radiologic, sonographic, serologic and molecular studies. Cytologic examination of the bone marrow revealed that dysmyelopoiesis and dysplastic changes were prominent in the erythroid cells. These changes included asynchronous maturation of the nucleus and cytoplasm, binucleation, trinucleation, fragmented or lobulated nuclei and multilineages. Mild dysgranulopoiesis and dysmegakaryocytopoiesis were also detected including pseudo Pelger-Huet anomalies, giant band neutrophils, asynchronous maturation of the nucleus and cytoplasm in granulopoiesis and large hypolobulated forms as well as dwarf megakaryocytes in megakaryocytopoiesis. Myelodysplastic syndrome and congenital dysmyelopoiesis was ruled out by the low number of blast cells. Finally, secondary dysmyelopoiesis associated with IMHA was diagnosed and immunosuppressive treatment was successfully responsive.

Anemia is a common problem in sick dogs, and immune-mediated hemolytic anemia (IMHA) is one of the most common causes of anemia in dogs. Since death can occur rapidly in dogs with IMHA even with appropriate treatment, it is important to differentiate IMHA from other causes of anemia in its first stages. To diagnose underlying diseases in anemic dogs and differentiate IMHA cases from others, 29 patient dogs suffering from severe anemia that had been referred to Veterinary Medical Teaching Hospital at a National University from June 2004 to April 2005 were examined. The most common cause of anemia in the patient dogs was found to be liver disease accounting for 31.0% (9/29) of all, and the second most common was IMHA with 13.7% (4/29). Four dogs confirmed as IMHA cases all reacted positive to direct anti-globulin test and showed spherocytes and polychromatic erythrocytes in the blood smear. Most of the IMHA cases (3/4) were female aged 2 to 7 years and were in a severe state of anemia with less than 20% of PCV.

Cytauxzoonosis is caused by Cytauxzoon felis (C. felis) in wild and domestic cats. However, cytauxzoonosis is uncommon in Asia. Additionally, clinical reports of C. felis infection along with associated complications are rare. A seven-year-old neutered male Maine Coon cat was presented with acute dyspnea and lethargy despite the absence of a history of overseas travel. Mild regenerative anemia and autoagglutination were detected in hematological investigations. The parasitic and viral PCR assays revealed infection with C. felis and feline immunodeficiency virus (FIV). Thoracic radiographs showed pleural effusion with secondary bacterial infection. Ultimately, a diagnosis of infection-induced secondary immune-mediated hemolytic anemia (IMHA) and pyothorax was established. The cat was treated with a combination of atovaquone, prednisolone, and cyclosporine over 6 months and the final treatment was completed 8 months after initiation of therapy. This is the first report of its kind demonstrating successful management of feline IMHA and fatal pyothorax induced by FIV and C. felis in South Korea.
