Canine leishmaniasis, a generally fatal parasitic disease, was diagnosed in 2 dogs with a medical history of foreign travel, lymphadenopathy, emaciation, anorexia, intermittent fever, and cutaneous lesions. Clinically, hyperproteinemia, proteinuria, azotemia, and glomerulopathy were evident. Isolation of Leishmania species was done using Schneider's Drosophila medium. Syrian hamsters were used for infectivity studies. Clear taxonomic identification was done biochemically by isoenzyme analysis and comparison of zymogram banding patterns with 6 World Health Organization reference strains. Based on the geographic origin of affected dogs, clinicopathologic presentation, visceralization with hepatosplenomegaly in hamsters, and isoenzyme analysis, a diagnosis of Leishmania leishmania infantum was made. This study, representing the first taxonomic identification of an isolate from canine leishmaniasis, demonstrates the zoonotic and epidemiologic implications of this disease.

Two children with prototypic hemolytic-uremic syndrome had prolonged acute dialysis-dependent renal failure (74 and 84 days) associated with a state of hyperproteinemia induced by extensive infusion of fresh frozen plasma (283 and 307 units). We believe that the hyperproteinemia prolonged the duration of renal failure. Following cessation of plasma therapy, the hyperproteinemic state reversed, the degree of proteinuria decreased and renal function quickly recovered. Although the pathophysiological mechanism requires further evaluation, we speculate that an alteration in the colloid oncotic pressure and/or aggravation of tubulointerstitial injury due to overload-proteinuria may have increased the duration of renal failure.

The authors have presented a review of literature and their own data on acute tubulointerstitial nephritis combined with uveitis in a patient aged 47. In foreign literature this combination is defined as a separate syndrome (TIN-uveitis or TINU). The development of nonspecific symptoms (fatigue, weakness, nausea, loss of body mass, pains in the joints, skin rash) was characterized by change in some laboratory indices (raised ESP, anemia, eosinophilia, hyperproteinemia, hypergammaglobulinemia) and nephropathy. The signs of nephropathy were polyuria, a decrease in relative urine density, proteinuria of tubular genesis, renal glucosuria and aminoaciduria. A decrease in glomerular filtration and an increase in the level of blood serum creatinine were noted in most of the cases. In spite of the development of renal failure TINU prognosis is favorable: renal function gets back to normal by itself or after corticosteroid therapy. Uveitis shows a tendency to recurrence. The immune genesis of the TINU syndrome is assumed.

Multiple myeloma was diagnosed in a horse on the basis of clinical signs, protein electrophoresis pattern, Bence-Jones proteinuria, and radiographic changes in bone. The horse had mild depression, weight loss, edema of the distal portion of the left hind limb, anemia, hyperproteinemia, and monoclonal gammopathy in the beta 2 region. Radiographically, punctate cortical lysis of bone was seen. Specific treatment for the multiple myeloma was not attempted and the horse was euthanatized.

Renal amyloidosis was diagnosed in 8 related Abyssinian cats. The kidneys were characterized pathologically by medullary interstitial and glomerular amyloid deposition, interstitial fibrosis, and papillary necrosis. Amyloid deposits were birefringent under polarized light after Congo red staining, were thioflavine-T positive, and lost Congo red staining after permanganate oxidation. Four of the cats were evaluated clinically. Two of these cats were terminally uremic, with nonregenerative anemia, azotemia, hyperphosphatemia, metabolic acidosis, mild hyperglycemia, isosthenuria, proteinuria, cylindruria, and mild hematuria. The remaining 2 cats were only moderately azotemic. Three of the cats had severe gingivitis and all 4 cats had hyperproteinemia due to hyperglobulinemia.

Plasma cell myelomas in horses have been reported infrequently. Data from 10 cases, 9 from the literature and 1 new case, are used to characterize the disease in the horse. Hot-blooded horses (7/10), specifically Quarter Horses (4/10), were most often affected. Median age at diagnosis was 11 years (range, 3 mo-22 yr) and both male (5) and female horses (5) were represented equally. Clinical findings included weight loss (6/8), anorexia (4/8), fever (4/8), limb edema (4/8), pneumonia (3/8), rear leg paresis/ataxia (3/8), epistaxis (3/8), palpable lymphadenopathy (2/8), and bone pain (2/8). Anemia (8/8) was present routinely, and in three horses, RBCs were macrocytic. Leukopenia (2/8), thrombocytopenia (2/8), and circulating plasma cells (3/8) were variable findings. Except for abnormal protein concentrations and hyponatremia (3), abnormal results from serum biochemical analysis including hypocholesterolemia (1), hypercalcemia (1), and azotemia (1) were reported infrequently. Hyperproteinemia (8/9), hypoalbuminemia (7/9), and hyperglobulinemia (8/9) were characteristic but not invariable findings. Monoclonal proteins (7/7) were detected in the alpha 2, beta, or gamma region by serum electrophoresis. The paraprotein's heavy chain, determined in four horses, was a subclass of IgG. Three horses had decreased concentrations of normal immunoglobulins. Variable proteinuria (trace to 4+) was detected by routine urinalysis in four of six horses. Bence Jones proteinuria was detected in one of five horses (heat precipitation) and monoclonal proteins were detected in two of three electrophoresed urine samples. Three of the horses had lytic bone lesions detected radiographically. Bone marrow aspirates were diagnostic in two of five horses.(ABSTRACT TRUNCATED AT 250 WORDS)

The medical records of 158 dogs with visceral leishmaniasis confirmed cytologically and/or serologically were reviewed. Ages of affected dogs varied from nine months to 15 years, with a male-to-female ratio of 1.3. The most common clinical manifestations of the disease were variable cutaneous lesions such as exfoliative dermatitis and skin ulcerations, chronic renal failure, peripheral lymphadenopathy or lymph node hypoplasia, masticatory muscle atrophy (i.e., chronic myositis), ocular lesions (i.e., conjunctivitis, keratoconjunctivitis sicca, blepharitis, and uveitis), and poor body condition. Ascites, nephrotic syndrome, epistaxis, polyarthritis, and ulcerative stomatitis were seen only in a small number of cases. Clinical splenomegaly was not a common finding. The clinicopathological abnormalities were nonregenerative anemia, hyperproteinemia, glomerular proteinuria, and symptomatic or asymptomatic azotemia. In this study, an indirect immunofluorescence assay's diagnostic sensitivity was found to be higher than that of lymph node aspiration cytology.

A 5-year old Tinker gelding was referred to the Department of Equine Sciences with a left eye uveitis and fever. At presentation the horse showed a mild lethargy, fever and decreased vision of the left eye. Rectal examination revealed an enlarged left kidney, with a hard and an irregular surface. The cranial mesentery artery had an enlarged and irregular aspect. Blood analysis showed anaemia, leucocytosis, increased blood urea nitrogen and creatinine and a hyperproteinemia. Urine analysis repeatedly showed a marked proteinuria and an increased gammaGT/creatinine ratio. The amount of abdominal fluid was slightly increased. However, the aspect, amount of cells and protein were normal. In the following two days the fever persisted and the horse showed anorexia and severe neurological signs. The horse was euthanized with permission of the owner. Post mortem examination showed a generalized parasitic infestation of Halicephalobus gingivalis in the uvea of the left eye, the kidneys and the central nerve system.

The present study aimed to evaluate the renal and hepatic responses in eight dogs with visceral leishmaniasis submitted to treatment with meglumine antimoniate and to verify the occurrence of possible side effects. Urinalysis, hepatic and renal function tests were carried out in all animals at up to seven moments. After the end of a six-month observation period, all dogs were euthanized. Before the beginning of the experiment urinary and biochemical alterations were observed in four dogs due to the changes caused by the parasite itself. These alterations included the presence of renal cells, cylindruria, proteinuria, azotemia, hyperproteinemia and hypoalbuminemia. One dog died on the third day after treatment because an aggravation of the clinical picture, probably due to the medication. During the course of the study, an increase in hepatic enzymes was verified in two animals. Sixty days after the beginning of the treatment four dogs showed remission of clinical signs. The other three were asymptomatic with persistent biochemical alterations. From these, two presented recurrence of clinical signs about 150 days after the beginning of the treatment while in the other, hyperproteinemia persisted. Meglumine antimoniate was not efficient to treat dogs with severe renal dysfunction and the side effects observed were pain at the site of injection and the probable transient hepatotoxicity, evidenced by biochemical examinations, but without the presence of clinical signs.

A 7-year-old neutered male domestic shorthair cat was presented to the Veterinary Medical Teaching Hospital at the University of Georgia for further evaluation of a suspected osteolytic lesion of the left 10th rib. Results of a CBC and biochemistry profile revealed mild nonregenerative anemia, hyperproteinemia, hyperglobulinemia, and hypercalcemia. Serum protein electrophoresis was consistent with a monoclonal gammopathy. Marked proteinuria with an increased urine protein to creatinine ratio was found. Cytologic examination of the liver, spleen, and bone marrow revealed numerous plasma cells, many of which were erythrophagocytic. Within the bone marrow, the plasma cells contained phagocytosed metarubricytes in addition to phagocytosed erythrocytes. A diagnosis of erythrophagocytic multiple myeloma was made and treatment with prednisone and melphalan was begun. Four weeks after presentation, the cat was euthanized due to clinical deterioration. A complete necropsy was performed. The distal one-third of the left 10th rib was completely absent. Histologically, there was no evidence for osteolysis or neoplastic cells in the remaining portion of the rib. However, large sheets of plasma cells were found infiltrating the spleen and bone marrow. Moderate erythrophagocytosis by the plasma cells was observed in both organs. The plasma cells, including the erythrophagocytic cells, were positive for CD79alpha by immunohistochemical staining. Erythrophagocytosis by plasma cells as a cause of anemia is uncommon in people with multiple myeloma and is rare in animals. To our knowledge, this is the first report of erythrophagocytic plasma cells in a cat with multiple myeloma.
