Pale chicks with necrotic dermatitis, small bursas of Fabricius (BFs), small thymuses, pale bone marrow, and watery blood were suspected of having parvovirus-like virus- (PVLV) associated disease. Histologic lesions included atrophy or hypoplasia of thymuses and BFs, and septic necrotizing clostridial dermatitis and hepatitis. Clostridium perfringens was cultured from skin and liver. A PVLV was isolated in a Marek's disease tumor cell line (MDCC-MSB1) culture and was identified by physicochemical, immunofluorescent, and morphologic features. This isolate was named GA-1 PVLV. Specific-antibody-negative chicks and embryos infected with heat- or chloroform-treated GA-1 PVLV developed anemia at the same rate. Control chicks never were anemic. This is the first isolation of PVLV from clinically ill chickens in the United States and the first report of PVLV-induced anemia in chickens in the Western Hemisphere.

Wild-caught African Vervet monkeys are commonly infected by Simian T-lymphotropic virus I (STLV1) and Simian immunodeficiency virus (SIV), yet the natural histories of these infections are largely unknown. Seropositivity was associated with increased total, T and atypical lymphocytes. In seropositive females there was mild, normocytic, normochromic anaemia. Lymphoid hepatitis was present in seven seropositive cases. African Vervets used in biomedical research, vaccine production and organ transplantation research are often infected by exogenous retroviruses which can be oncogenic and immunosuppressive in captive monkeys. Elimination of these infections may be possible by breeding Vervets in captivity.

Transfusion of homologous blood components is associated with immunological (incompatibility, alloimmunization, immunosuppression) and infectious risks (hepatitis, cytomegalovirus, HIV and other agents). Endoprosthetic surgery of the hip and knee frequently requires transfusion. Preoperative deposit of autologous blood can reduce homologous transfusion requirements. The simplest method is liquid storage of whole blood. In order to re-examine the efficiency of our present scheme of preoperative deposit, we studied patients scheduled for endoprosthetic surgery with respect to the amount of blood deposited, stimulation of erythropoiesis, and homologous blood requirements at the time of operation. PATIENTS AND METHODS. Sixty-seven consecutive patients (33 men, 34 women) scheduled for endoprosthetic replacement of hip or knee or for revision arthroplasty of the hip were studied. Patients with anemia, coagulopathies, coronary heart disease, severe obstructive or restrictive pulmonary disease, cerebral sclerosis, syncopes and seizures were excluded from preoperative deposit. Patients deposited 450 ml at weekly intervals, with occasionally slightly higher or lower volumes. A patient was temporarily deferred when the hemoglobin concentration prior to donation fell below 11 g/dl. Blood was collected in CPDA-1 buffer. The aim was a deposit of three units. In patients undergoing exchange reoperation of a total hip arthroplasty, intra- and postoperative autotransfusion with a cell separator was employed in addition to preoperative donation. RESULTS. The age of the patients ranged from 43 to 83 years (mean +/- SD: 61.2 +/- 9.1). The differences between men and women with respect to height (172.9 +/- 6.8 vs 160.6 +/- 7.4 cm; p less than or equal to 0.001), weight (75.7 +/- 11.2 vs 69.1 +/- 11.0 kg; p less than or equal to 0.05), calculated blood volume (p less than or equal to 0.001), and erythrocyte volume prior to donation (p less than or equal to 0.001) were significant. A total of 185 units was deposited. Men donated 1350 (450-1970) ml blood (median, range) and women 1260 (340-1450) ml (p less than or equal to 0.01). Hemoglobin concentrations decreased significantly from an average of 14.7 g/dl in men and 13.8 g/dl in women prior to donation to 13.4 g/dl and 12.3 g/dl preoperatively (p less than or equal to 0.0001 for both groups). The donation was not associated with serious complications. For 4 patients the scheduled operation was deferred for a longer term. Forty-six patients (23 men, 23 women) underwent total hip arthroplasty, 12 (4 men, 8 women) exchange of total hip arthroplasty, and 5 (3 men, 2 women) endoprosthetic knee surgery. In total hip arthroplasty men required 0 to 500 ml homologous packed red cells (median=0), women 0 to 1250 ml (median=0;p less than or equal to 0.05). Thirty-nine (69.6%) of the patients, 19 (82.6%) men and 13 (56.5%) women, did not require homologous transfusion.(ABSTRACT TRUNCATED AT 400 WORDS)

The traditional options available for the correction of hemodialysis-related anemia are blood transfusions and androgen therapy to stimulate erythropoiesis. A new therapeutic option, recombinant human erythropoietin (r-HuEPO; EPOGEN, AMGEN Inc, Thousand Oaks, CA), is currently undergoing clinical trials. Each treatment alternative has certain attendant adverse effects. The adverse effects of transfusion include transmission of infections such as hepatitis or acquired immunodeficiency syndrome, iron overload, and sensitization to histocompatibility antigens. Androgen therapy can cause masculinization of women and children and, in some forms, is associated with a high incidence of abnormal liver function. Treatment with r-HuEPO has some potential adverse effects, including hypertension, thrombosis of arteriovenous fistulae, prolonged duration of dialysis, hyperkalemia, and iron deficiency. Gradual and careful introduction of r-HuEPO should prevent hypertension from becoming problematic.

In 21 children with weakened immune response++ (18 patients after immunosuppression and/or after radiotherapy because of neoplastic disease, 1 patients with diagnosed hepatitis chronica persistens, 1 patient with streptococcal septicemia and one infant with protein deficiency and severe anemia) Zovirax was applied in treatment of Varicella virus infection. Clinical observation showed a positive effect of Zovirax in treatment of VZV infection which was manifested by a milder course of the infection and disappearance symptoms. Better effects were obtained when the treatment was started in the first 72 hours of infection.

Subacute fascioliasis was diagnosed by pathomorphological and parasitological investigations on 13 dead moufflons (Ovis ammon musimon) from a herd of 21 animals (mortality 62%) which had succumbed between January and April 1988. The flock had been kept on meadow in the so-called Leipziger Auenwald. The main findings like severe hepatitis traumatica fasciolosa, fibrinous and fibrous perihepatitis, chronic interstitial hepatitis (pseudocirrhosis), cholangitis fasciolosa (X 13), wasting (X 8), heart dilatation (X 10), lung oedema (X 12), anemia (X 5), ascites (X 3), gut oedema (X 3) and occasionally observed lesions are described in detail and discussed with regard to diagnosis and pathogenicity. Beside severe infection with Fasciola hepatica (juvenile and adult flukes) the parasitological investigation demonstrated, in some cases, various additional but unimportant infections with protostrongylids, gastro-intestinal nematodes, coccidia (X 2) and Moniezia expansa (X 1). The analysis of meteorological data (January 1987 till March 1988) established optimal conditions for F. hepatica development stages and Galba truncatula so that high multiplication and infection rates of the snails and long surviving of metacercariae must be assumed.

The presentation and subsequent course of respiratory syncytial virus (RSV) bronchiolitis may be atypical and unusually severe when simultaneous infection due to other pathogenic agents is present. During the past two years, nine of the 189 pediatric patients hospitalized with documented RSV infection were found to have the following simultaneous isolates from initial respiratory tract specimens: four adenovirus, four pneumococcus, one cytomegalovirus, and one Pneumocystis carinii. Noted complications attributable to the second pathogen included thrombocytopenia and anemia (cytomegalovirus), hepatitis and disseminated intravascular coagulation (adenovirus), and sepsis and osteomyelitis (pneumococcus). Three of the four patients with RSV and adenovirus died of severe respiratory failure despite mechanical ventilation; two of these patients received ribavirin therapy. Rapid identification of RSV is important but should not be a substitute for more comprehensive viral and bacterial evaluation.

A 24-year-old patient was admitted to our hospital because of vertigo, coldness and exercise-dependent pain in the left arm. She reported to have suffered from tuberculosis of the lung and a non-A-non-B hepatitis five years ago. Angiography of the aorta thoracica revealed a complete obstruction of the left arteria (a.) subclavia, stenosis of the a. carotis communis on both sides, of the a. carotis interna and the a. vertebralis on the left side as well as a non-detectable perfusion of the upper and medium segment of the left lung. ESR was elevated with 89/128 mm n.W., a hypochromic anaemia, thrombocytosis, hypalbuminaemia, elevation of alpha 2 and gammaglobulins in serum as well as a reduced quick value were found. AT III and protein C concentrations in plasma were also decreased, whereby protein C activity was reduced additionally. HLA-B-51 was positive. Takayasu's arteriitis was diagnosed by us. High-dose treatment with corticosteroids led to a considerable improvement of the clinical status and laboratory parameters of the patient. As this therapy was not associated with a normalization of protein C and AT III concentrations in plasma, protein C and AT III deficiency could be of significance in the development of Takayasu's arteriitis. Until now protein C and AT III deficiency were not described in patients with Takayasu's arteriitis.

Human parvovirus is the causative agent of erythema infectiosum, a mild epidemic illness. In a recent outbreak in northeast Scotland, six women had serologic evidence of having contracted human parvovirus infection during pregnancy. Two of the women had midtrimester abortions, and both abortuses were grossly hydropic with anemia. They had similar microscopical histopathological features--a pronounced leukoerythroblastic reaction, hepatitis, excessive iron pigment in the liver, and eosinophilic changes in the hematopoietic cell nuclei. Dot hybridization with radiolabeled human parvovirus DNA probes revealed viral DNA in several tissues from both fetuses, indicating that they had been infected by the virus in utero. The remaining four women had uncomplicated pregnancies and delivered apparently healthy babies, none of whom had human parvovirus-specific IgM antibody at delivery. We conclude that this common virus may pose a serious risk to the fetus after maternal infection.

Feline leukemia virus (FeLV) infection was diagnosed immunohistologically on paraffin-embedded tissues obtained from 1,095 necropsied cats. Significant association of FeLV infection was demonstrated by chi 2 and Fisher's tests with various conditions and diseases (ie, anemia, tumors of the leukemia/lymphoma complex, feline infectious peritonitis, bacterial infections, emaciation, FeLV-associated enteritis, lymphatic hyperplasia, and hemorrhage). Unexpected findings associated with FeLV infection were icterus, several types of hepatitis, and liver degeneration. A negative association with FeLV infection was found for most parasitic and viral infections, including feline panleukopenia. Neither positive nor negative associations were established for FeLV infection and most forms of nephritis, including severe glomerulonephritis. Feline leukemia virus-infected cats were significantly (Kruskal-Wallis test) older than were FeLV-negative cats with the same nonneoplastic FeLV-associated diseases.
