A 36-year-old man had pain in both knees and an elevated uric acid concentration; his liver function was normal. Allopurinol therapy was started, 100 mg twice daily. After one month fever, lethargy, and severe polyarthralgia developed. On admission to our hospital liver function was abnormal, and a liver biopsy specimen showed granulomas with cholangitis and pericholangitis. He also had lymphopenia with a reduced number of T cells and granulomas in the bone marrow. One month after discontinuation of allopurinol therapy the patient was clinically well with normal liver function and a normal lymphocyte count. A repeated liver biopsy specimen showed normal liver tissue with no granulomas. The onset of the symptoms and findings shortly after the initiation of allopurinol therapy, and their disappearance after the discontinuation of therapy suggest a drug-induced hypersensitivity.

A porcine strain of Pasteurella multocida (serotype D:3) produced a toxin causing turbinate atrophy (TA) in pigs. The toxin (TAT), processed on a high performance liquid chromatography size exclusion column, eluted as a single peak (molecular weight of about 160,000) containing trace amounts of endotoxin (lipopolysaccharide, LPS; protein:LPS, 85:1). The eluted fraction migrated on sodium dodecyl sulfate polyacrylamide gels as a single band. It could be prevented from dissociating into two prominent polypeptides by addition of a protease inhibitor. A single dose (2.0 to 79.0 micrograms/kg) of TAT given to pigs intravenously was lethal. Doses from 0.02 to 1.0 microgram/kg caused transient clinical signs of porcine systemic toxicosis with reduced appetite, generalized weakness, depression, lethargy, weight loss, and in some instances, death. Intradermal doses of TAT (greater than or equal to 0.1 microgram/site) produced hemorrhagic areas within four hours. Systemically, TAT causes bilateral TA, lymphopenia, liver dysfunctions, and possible renal impairment. Affinity of TAT for cells of epithelial origin was demonstrated in mice given 125I-TAT. In vitro, TAT stimulated DNA and protein syntheses of peripheral blood lymphocytes and suppressed syntheses in turbinate and kidney cell cultures without being cytolytic. Biological effects of TAT were eliminated by exposure to either heat, trypsin or anti-TAT antibody.

The first case of canine ehrlichiosis in Connecticut is reported. A female Brittany spaniel from Milford presented with lethargy, anorexia, fever, petechiae, splenomegaly, thrombocytopenia, anemia, elevated serum alkaline phosphatase, lymphopenia, and hypoalbuminemia. Serologic analysis revealed antibodies to Ehrlichia canis (titer, 1:2,560). This documents a more northern geographic distribution in the United States for this infectious agent than had previously been suspected.

The clinical and haematological changes which occurred in 18 Bali cattle (Bos javanicus) experimentally infected with Jembrana disease are described. The major clinical signs were an elevated rectal body temperature persisting for 7 days (range 5 to 12 days), lethargy, anorexia, enlargement of the superficial lymph nodes, a mild ocular and nasal discharge, diarrhoea with blood in the faeces and pallor of the mucous membranes. Not all of these changes occurred in all affected cattle. The major haematological changes included leucopenia, lymphopenia, eosinopenia and a slight neutropenia, a mild thrombocytopenia, a normocytic normochromic anaemia, elevated blood urea concentrations and reduced total plasma protein. The mortality rate in the experimentally infected cattle was 17 per cent. The similarity of Jembrana disease to malignant catarrhal fever and to diseases of cattle associated with Ehrlichia is discussed.

Thirty-two cats referred to the Feline Studies Centre between June 1987 and October 1988, and 14 in-contact cats, were found to be infected with feline immunodeficiency virus. Most of the 46 cats were non-pedigree and free ranging; 27 were male (19 neutered) and 19 were female (18 neutered). Their ages ranged from one to 17 years and the average age was 5.8 years. The most common clinical signs were lethargy, inappetence, weight loss, pyrexia and lymphadenopathy; most cases had multiple abnormalities. Other common signs were gingivitis, diarrhoea, rhinitis and ocular discharge. Eight cats had neoplasia. The commonest haematological abnormalities were anaemia, neutropenia, lymphopenia and monocytosis. Eight cats had lymphocytosis; seven of these were in a single house-hold. Several cats had high serum globulin levels and half of those tested had high IgG levels. Seven cats had no detectable antibody to feline immunodeficiency virus even though the virus was cultured from the peripheral blood lymphocytes. During follow-up for up to 60 weeks one cat died and 23 were destroyed on humane grounds.

The medical records of 59 dogs with renal amyloidosis were reviewed. Most dogs with amyloidosis were greater than 6 years old, and females were affected more often than males. Beagles, Collies, and Walker Hounds were at increased risk, whereas German Shepherd Dogs and mixed-breed dogs were at decreased risk. Common historical findings were anorexia, polyuria, polydipsia, lethargy, vomiting, and weight loss. Common laboratory findings were leukocytosis, lymphopenia, nonregenerative anemia, hypercholesterolemia, azotemia, hyperphosphatemia, metabolic acidosis, isosthenuria, cylindruria, and proteinuria. Proteinuria was moderate to severe in most dogs, as assessed by qualitative determination of urine protein concentration, urine protein/urine creatinine ratio, and 24-hour urine protein excretion. Conservative medical management was of little value, and survival ranged from 3 to 20 months in 12 dogs for which this information was available. Moderate to severe diffuse global glomerular amyloidosis was detected in all dogs. Medullary amyloid deposition was multifocal and less severe, but was evident in most dogs. Secondary tubulointerstitial and glomerular lesions were mild or absent in most dogs. Thromboembolism was identified in approximately 14% of affected dogs, underlying inflammatory disease in 37%, and neoplasia in 20%. Laboratory indicators of renal function correlated poorly with histologic lesions, with the exception of glomerular amyloid deposition and "chronic renal disease" index with endogenous creatinine clearance.

15 patients aged between 24 and 66 years with 10 different malignant tumor diseases were treated with a recombinant human tumor necrosis factor preparation PAC-4D in a phase-I trial. The starting dose was 10(5) U PAC-4D as an intravenous short infusion. The maximally tolerable dose is around 18 X 10(5) U/m2. As the main clinical side effects were observed: fever, chills, hypertension with subsequent hypotension, lethargy, transient somnolence, headache, neurological deficiency symptoms, nausea and vomiting. Important laboratory-chemical parameters were the increase in transaminases and, in higher dose levels, leukocytosis with the left shift and lymphopenia in the differential blood picture. As dose-limiting toxicity are estimated hypotension, and neurological side effects and hepatotoxicity. In one female patient who received 27 X 10(5) U PAC-4D there appeared pronounced, histologically verified necroses in the metastases of a malignant fibrous histiocytoma.

We have developed a rabbit model of toxic shock syndrome that uses a subcutaneous infusion pump to administer toxic shock syndrome toxin 1 (TSST-1). A dose of 150 micrograms, infused at a constant rate over a period of 7 days, resulted in a characteristic illness highlighted by fever, conjunctival hyperemia, cachexia, and lethargy. The illness was uniformly fatal, with a mean interval until death of 3.2 +/- 0.4 days. Serial determinations of serum chemistries confirmed the multisystem nature of this illness. Rabbits developed profound hypocalcemia, with levels falling from 15.5 +/- 0.2 to 7.6 +/- 0.4 mg/dl under the influence of TSST-1. Blood urea nitrogen and creatinine rose dramatically, in the setting of oliguria or anuria. Serum glutamicpyruvic transaminase was the most reliable indicator of hepatic dysfunction, with the mean rising from 48 U/liter before administration of TSST-1 to 546 U/liter among rabbits surviving 2 days of the infusion. Creatine phosphokinase also rose dramatically in 10 of 16 rabbits. Rabbits demonstrated relative neutrophilia and lymphopenia as well as an increase in the partial thromboplastin time. Histopathologic examination demonstrated disease of multiple organs, particularly the liver, spleen, and lymph nodes, all of which demonstrated inflammation, thrombosis, hemorrhage, and erythrophagocytosis. The concurrent administration of prednisolone with TSST-1 prevented death in four of four rabbits and greatly lessened the morbidity. Rabbits were not protected from morbidity or mortality by the concurrent administration of polymyxin B. We believe that a constant, subcutaneous infusion of TSST-1 in rabbits provides a reproducible model for studying the pathogenesis of TSS.

The historic, physical, laboratory, and histologic findings for 74 cats with chronic renal disease were reviewed. Most cats were older, and no breed or sex predilection was detected. This most common clinical signs detected by owners were lethargy, anorexia, and weight loss. Dehydration and emaciation were common physical examination findings. Common laboratory findings were nonregenerative anemia, lymphopenia, azotemia, hypercholesterolemia, metabolic acidosis, hyperphosphatemia, and isosthenuria. The most common morphologic diagnosis was chronic tubulointerstitial nephritis of unknown cause. The other pathologic diagnoses were renal lymphosarcoma, renal amyloidosis, chronic pyelonephritis, chronic glomerulonephritis, polycystic renal disease, and pyogranulomatous nephritis secondary to feline infectious peritonitis.

Of cases of hyperadrenocorticism in small animals 80-85% are the result of adrenocortical hyperplasia. Middle-aged or older Poodles, Dachshunds, Boston Terriers and Boxers are most commonly affected, and cats rarely. Clinical signs include polydipsia, polyuria, alopecia, abdominal distension, lethargy, weakness, hepatomegaly, calcinosis cutis, testicular atrophy and anestrus. Hematologic and biochemical changes may include neutrophilia, lymphopenia, monocytosis, eosinopenia, increased blood levels of alkaline phosphatase, SGPT, cholesterol, Na and glucose, and decreased K and T4 levels. The high-dosage dexamethasone suppression test helps differentiate pituitary-dependent hyperadrenocorticism from that caused by adrenal tumors. The low-dosage dexamethasone suppression test, determination of plasma ACTH levels, and ACTH response test are additional diagnostic aids in the diagnosis of Cushing's disease. Medical treatment involves oral use of mitotane (o,p'-DDD) at 50 mg/kg/day for 7 days and prednisone or prednisolone at 0.05 mg/kg/day. Hypophysectomy has been used with only 5% mortality in cases of pituitary-dependent hyperadrenocorticism. Adrenalectomy is indicated in cases of adrenal neoplasia.
