Fifty patients with lymphocytic lymphoma and chronic lymphocytic leukemia underwent splenectomy for various combinations of anemia, thrombocytopenia, and leukopenia. All of these patients had advanced lymphoproliferative disease, and most had infiltration of bone marrow by neoplastic cells. Good response in all hematologic parameters was obtained in 27 of 48 evaluable patients. An additional 13 patients responded in one or two parameters; there were only 8 complete failures. The over-all surgical mortality was 8%. The median duration of response was 4 months, and the mean, 7 months. Increased tolerance to further antitumor therapy and a decreased transfusion requirement were seen among responding patients. Those patients with anemia who had evidence of shortened erythrocyte survival and splenic sequestration of 51Cr-labelled erythrocytes uniformly responded with rises in hemoglobin. However, half of the patients with negative splenic sequestration also showed improvement of anemia. Preoperative diagnostic studies failed to predict favorable responses of patients with thrombocytopenia or leukopenia. The classical criteria for the diagnosis of hypersplenism are not applicable in many cases of neoplastic lymphoproliferative disease; splenectomy could have been considered "contraindicated" in most of the patients in this series. We conclude that splenectomy is worth undertaking in patients with lymphoproliferative disease complicated by hematologic depression regardless of marrow findings or the results of other diagnostic studies.

Between May and September 1973, 68 cases of scrub typhus in Chinese military personnel on the Pescadores Islands were studied. The common symptoms and signs were fever, chills, headache, eschar, myalgia, and lymph node enlargement. Most eschars were located in the axilla, waist, groin and genitals, and neck. These lesions were painless and not noticed by the patients themselves. Regional lymph node enlargement at the site of eschar drainage was common. Relative bradycardia with fever was observed in 40%, a skin rash in 35% of the patients. Leucopenia was noted more frequently in the febrile than in the convalescent stage, but more than half of the patients had a normal count. Lymphocytosis was prominent, especially during the convalescent period. An acceleration of ESR was noted. Instead of depression of the erythroid series in the marrow which was reported previously, 47% of examined patients were found to have erythroid hyperplasia. Two patients showed marked hypocellularity of the marrow in the acute febrile stage; later on became normocellular. Albuminuria was present in 15 and BUN increased in 12 patients. Elevation of serum bilirubin and SGOT was also noted. Biologic false positive VDRL tests were observed in nine patients. In 30 tests elevation of Proteus OX-K titres between 1:160 and 1:640 was noted. A geometric mean OX-K titre rise in the patients is presented; the mean titre reached a peak in the third week of illness, and then fell off. Most of the patients were treated with tetracycline 500 mg every six hours for about nine days. The fever usually subsided within 36 hours. Complications or mortality were not encountered.

Two cases of irreversible bone marrow failure are described, one with rheumatoid disease and one with systemic lupus erythematosus. Each case was associated with prior chlorambucil administration, effective in controlling the clinical manifestations (total dosage 398 and 1,764 mg respectively). The irreversibility of the bone marrow depression in the two cases presented stands in contrast to published assurances that chlorambucil-associated leukopenia is dose-related and readily reversible. The cases illustrate that chlorambucil therapy should not be continued after initial leukopenia, until peripheral counts or marrow cellularity has returned to normal. Titration of drug dosage and leukocyte count, as frequently employed with cyclophosphamide and other alkylating agents, must be presumed hazardous. Additional studies are needed to determine if irreversible bone marrow depression is dose-related or idiosyncratic.

The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

The influence of dexamethasone and cyclophosphamide on the goat immune system was investigated. Seven goats, with a previous contact with caprine herpesvirus type 1 (CHV-1), were used. All had been vaccinated with live Mycobacterium paratuberculosis vaccine. Six goats were injected intravenously (i.v.) with dexamethasone daily for 5 days (2.5-4 mg/kg BW per day). Three also received 25 mg/kg BW of cyclophosphamide on day 0. The seventh goat was not treated. Dexamethasone alone caused depression, slight lymphopenia and fall in tuberculin reaction. Dexamethasone plus cyclophosphamide caused a severe clinical reaction, marked leukopenia (lymphopenia and polymorphopenia), fall in tuberculin reaction and significant increase in CHV-1 neutralizing antibody titres. M. paratuberculosis antibody reaction was variable and thus difficult to be assessed. CHV-1 was not isolated.

Erythroderma as a manifestation of graft-versus-host disease after cardiac operations with blood transfusion may occur more frequently in Japan than in other countries. We have seen this problem in five patients who, after heart operations, died with symptoms and signs characteristic of graft-versus-host disease: cutaneous eruption, fever, diarrhea, leukopenia associated with agranulocytosis, and liver dysfunction. In the three patients seen most recently, skin biopsy showed findings similar to those of graft-versus-host disease after bone marrow transplantation. In addition, immunologic investigation showed remarkable differences in the findings in these patients and in those who did not have a graft-versus-host disease-like syndrome after cardiac operations. In particular, interleukin-2 production in response to mitogen stimulation was markedly diminished after operation in our patients, and the ratio of OKT4+ cells to OKT8+ cells in peripheral blood was low, reflecting increased numbers of OKT8+ cells after the occurrence of symptoms. The results raise the possibility that transient depression of cellular immunity after cardiac operations with blood transfusion may contribute to the occurrence of postoperative acute graft-versus-host disease.

A total of 12 patients with advanced renal cell carcinoma received interferon alpha (3 million units intramuscularly 6 times weekly) and OK-432 (5 KE (Klinische Einheit) intramuscularly twice weekly). Metastatic lesions appeared before operation in six patients and after operation in six patients. Among them 5 patients had received interferon therapy and this combination therapy was started after the judgment of progressive disease for interferon therapy. Eleven pulmonary and 5 bone metastases were evaluable. The median duration of the combination therapy was 89.3 weeks. There were 4 partial responses and no complete responses among the 12 patients, giving a response rate of 33.3%. The median duration of response was 25 months, with a range of 6 to 54 months. Responses were seen predominantly in patients in whom metastases appeared after operation (3 of 4 responders). However, regarding the individual organs, two complete and 2 partial responses were observed among 11 pulmonary metastases and 2 partial responses among 5 bone metastases. The survival period after discovery of the metastasis was 10 to 67 months and the 5-year survival rate was 70.5%. Almost all patients had fever and induration at the injection site. Other side effects included leukopenia, anorexia, and depression. This combination therapy is thought to be effective against bone or other organs metastasis resistant to interferon alone.

The effect of an intravenous bolus injection of endotoxin, 0.1, 1 or 10 micrograms/kg, on rectal temperature, clinical appearance, haematological parameters, and on gastrointestinal electrical activity was examined in 11 conscious piglets of 4-5 weeks of age, with implanted electrodes in the antrum pylori, duodenum, jejunum and ileum. All doses resulted in a significant and dose-dependent increase in rectal temperature, in pronounced clinical signs and in distinct changes in haematological values. These included shivering, depression, respiratory distress, a leukopenia (0.1 micrograms/kg) or a leukocytosis (1 microgram/kg) with a shift to the left, an accelerated sedimentation rate and a decreased packed cell volume. Doses of 1 and 10 micrograms/kg induced a transient inhibition of gastroduodenal electrical activity. These results suggest that, in the piglet, endotoxin primarily manifests general clinical signs and that the gastrointestinal effects coincide with these.

Healthy yearling beef and dairy cattle were inoculated with a vaccine containing modified-live bovine respiratory syncytial virus (ML-BRSV), and sequential changes in clinical signs of disease, blood leukocyte subsets, BRSV-specific antibody titer, and in vitro lymphocyte blastogenic responses were monitored. Vaccination with ML-BRSV did not cause pyrexia, local or systemic hypersensitivity reaction, or respiratory tract disease. Episodes of leukopenia, abnormalities in lymphocyte subsets, or depression of phytomitogen-induced blastogenic responses were not observed subsequent to vaccination. Exposure to ML-BRSV resulted in at least a 16-fold increase in serum neutralizing antibody titer, with no increase seen in nonvaccinated contact controls. Significant BRSV-specific lymphocyte blastogenic responses were not detected, using one dose of several BRSV antigen preparations in a whole blood culturing system.

A phase I study with continuous infusion carboplatin for 21 days every 6 weeks using a venous access port and portable pump was performed over a dose range of 12 to 32 mg/m2/d, with increments of 2 mg/m2/d. Forty-four patients received 107 courses (median, two; range, one to nine). World Health Organization (WHO) grade III/IV leukopenia and thrombocytopenia occurred in one of seven patients at 30 mg/m2/d, and in two of six and four of six patients at 32 mg/m2/d. Cumulative platelet depression was found at dose levels of 28 mg/m2/d or more. Median glomerular filtration rate (GFR) and effective renal plasma flow, monitored by radioisotope clearances at doses greater than or equal to 20 mg/m2/d, decreased 8.2% (P less than .05) and 10.9% (P less than .01) after two courses. There was a relationship (r = .50, P less than .0002) between the percentage of platelet depression and GFR. No other toxicity was observed. Of the 17 patients who were evaluable, one complete response and four partial responses were observed. In addition, six patients had stable disease. Pharmacokinetic analysis of total and ultrafiltrable platinum (UFPt) was performed by atomic absorption spectrophotometry. Steady-state plasma levels for UFPt were reached after 8 hours. These levels could be detected from the 20 mg/m2/d dose. During steady state, carboplatin dose and UFPt plasma levels were not correlated, but steady-state UFPt and GFR (r = -.27, P less than .05) were. Twenty-four percent of total platinum (Pt) was present as UFPt during steady state (x = 160 +/- 10 micrograms/L). Total body clearance of UFPt exceeded GFR 2.2 times. Mean area under the curve (AUC) for UFPt during continuous infusion was 4,921.8 +/- 301.72 mg.min/L. For total Pt, steady-state plasma levels were not reached; total Pt plasma levels increased between day 7 and day 21 (P less than .0001). There was a significant relation between total Pt serum levels day 7, 14, and 21 and the drug dose administered. Immunohistochemical analysis of DNA-bound Pt in leukocytes showed a linear increase from day 7 to day 14 to day 21 (r = .97) between DNA-bound Pt and duration of infusion in individual patients. The maximum-tolerable dose of carboplatin is 30 mg/m2/d for 21 days (total dose 630 mg/m2) and is recommended for phase II studies.
