Under the treatment with ampicillin or oxacillin resp. hematologic changes turn up very rarely except for eosinophilia, in addition it is only granulocytes or platelets alone which are involved in the cases yet published. In the case presented here therapy by an ampicillin/Oxacillin combination induces bone marrow depression with peripheral pancytopenia on a toxic or allergic base.

Twenty-six patients with mycosis fungoides were treated topically with three nitrosourea compounds: carmustine (BCNU), lomustine (CCNU), and 1-methyl-1-nitrosourea. A high percentage experienced good to excellent results. Remissions following treatment of individual lesions varied from one month to at least three years. Remissions following total body surface treatment varied from two weeks to at least four months. Two of 13 patients treated over the entire body suffered temporary bone marrow depression, indluding one with severe pancytopenia. This toxic effect was attributed to lomustine and was not seen in patients treated with carmustine alone. Thirteen patients highly allergic to mechlorethamine hydrochloride showed no cross-sensitivity to nitrosourea compounds. A primary irritant dermatitis occurred in about one half of the patients and telangiectasia in two. Two patients developed hypersensitivity to nitrosourea compounds. Carmustine is the preferred nitrosourea compound for topical therapy of mycosis fungoides.

So-called "Postoperative Erythroderma" was experienced in a 68 year-old man who received CABG for unstable angina. After a seemingly uneventful recovery, he revealed high grade fever on 13th post operative day (POD), rashes over the whole body on 15th POD and pancytopenia on 20th POD. He died of sepsis, multiple organ failure and DIC on 21st POD. Blood transfusion (concentrated red cell: 3 units) was done on operation. In this case, the rate of premature and atypical lymphocytes increased, and the ratio of OKT4 (helper)/OKT8 (suppressor) decreased. These findings of the examination suggested that there was a possibility of cell-mediated immunological depression. We considered this to be acute GVHD after blood transfusion.

Mice ingesting 30 to 50% D2O (heavy water, deuterium oxide) developed a dose-dependent depression of formed peripheral blood elements in 4 to 9 days. The principal mechanism of anemia and thrombocytopenia is impaired hematopoiesis. Despite pancytopenia in the peripheral blood, bone marrow cellularity and morphology remained normal. Upon replacement of D2O with tap water, platelet and neutrophil concentrations returned to normal within 48 to 72 hr. In contrast, blood lymphocyte concentrations remained low for several weeks. B-lymphocytes may be more affected by deuteration than other lymphocyte subsets. In vivo reticuloendothelial cell function, as assessed by 51Cr-labeled sheep erythrocyte clearance, was unaffected by D2O. Although a dose-dependent decrease in fluid intake occurred during deuteration, hematocytopenia was not a consequence of dehydration. In view of the known kinetics of D2O in biological systems, the rapid response of myeloid elements to deuteration must be due primarily to the solvent (nonmetabolic) isotope effect. Prolonged deuteration has proven toxic when included in regimens for treatment of neoplasia, including leukemia, in animal models. The present study shows that modulation of hematopoiesis by D2O is possible without invoking the toxicities associated with prolonged deuteration.

A case of a male patient with bronchopneumonia incorrectly treated for a long time with methacycline (rondomycin), an oxytetracycline drug, is reported. methacycline was applied in a dose of 8 capsules daily (2 capsules 4 times) in the course of 2 1/2 months, the total dose amounting to about 150 g. The patient developed severe toxic hepatitis as a result of this incorrect treatment. The hepatitis was manifested by jaundice and cytolysis. The bone marrow was also affected--hypoplasia marked by combined depression of leuko-, erythro- and thrombopoiesis and peripheral pancytopenia. In addition chloramphenicol treatment was applied which increased the toxic impairment of the liver and the bone marrow. The liver and bone marrow impairment are most probably due to the direct toxic action of methacycline applied for a very long time in an unusually high dose.

Benzene is one of the world's major commodity chemicals. It is derived from petroleum and coal and is used both as a solvent and as a starting material in chemical syntheses. The numerous industrial uses of benzene over the last century need not be recounted here, but the most recent addition to the list of uses of benzene is as a component in a mixture of aromatic compounds added to gasoline for the purpose of replacing lead compounds as anti-knock ingredients. The best known and longest recognized toxic effect of benzene is the depression of bone marrow function seen in occupationally exposed individuals. These people have been found to display anemia, leucopenia, and/or thrombocytopenia. When pancytopenia, i.e., the simultaneous depression of all three cell types, occurs and is accompanied by bone marrow necrosis, the syndrome is called aplastic anemia. In addition to observing this decrease in humans and relating it to benzene exposure, it has been possible to establish animal models which mimic the human disease. The result has been considerable scientific investigation into the mechanism of benzene toxicity. Although the association between benzene exposure and aplastic anemia has been recognized and accepted throughout most of this century, it is only recently that leukemia, particularly of the acute myelogenous type, has been related to benzene. The acceptance of benzene as an etiological agent in aplastic anemia in large measure derives from our ability to reproduce the disease in most animals treated with sufficiently high doses of benzene over the necessary time period. Unfortunately, despite extensive efforts in several laboratories, it has not been possible to establish a reproducible, reliable model for the study of benzene-induced leukemia. The recent demonstration that several animals exposed to benzene either by inhalation or in the drinking water during studies by Drs. B. Goldstein and C. Maltoni suggests that such a model may be forthcoming. Nevertheless, at this time it is not clear whether bone marrow damage of the type that leads to aplastic anemia is required for the development of leukemia. Most studies of benzene toxicity have involved dosing animals with benzene either by inhalation or by injection, using high doses to ensure a toxic response. Very few studies have concentrated on the oral route of administration and none have concentrated on administering benzene by mouth at the low doses occasionally detected in drinking water.(ABSTRACT TRUNCATED AT 400 WORDS)

A patient with the acquired immune deficiency syndrome experienced pancytopenia during the course of his illness. At the time of maximum depression of the blood cell counts, the hematocrit value was 21%; the WBC count, 1,000/cu mm; and the platelet count, 27,000/cu mm. Lymphopenia was persistent but the number of juvenile neutrophilis was not diminished. Peripheral blood smears were noteworthy for the presence of atypical monocytes with phagocytic vacuoles. Histiocytic hemophagocytophagia was prominent in bone marrow aspirate specimens. Bone marrow biopsy specimens were usually hypocellular and contained collections of atypical lymphocytes and increased reticulin. These hematologic abnormalities are most likely the consequence of persistent viral infection in an immunocompromised host.

A 77-year-old man received cefoxitin for the treatment of peritonitis. He developed hemolytic anemia and became clinically jaundiced. The patient was switched from cefoxitin to doxycycline. His total bilirubin decreased and his hematocrit increased. Several weeks later he developed septicemia. For an infiltration in the left lower lobe, he was treated with cefoxitin and gentamicin. The patient proceeded to develop a mild granulocytopenia and thrombocytopenia. Anemia was not seen because the patient was transfused several times. Bone marrow aspiration showed a mildly hypocellular marrow with a depression of all cell series, suggesting drug-induced bone marrow toxicity. Nine days after discontinuing cefoxitin, his blood elements had gone back to normal. This is the fourth case on file at Merck Sharp & Dohme of hemolytic anemia induced by cefoxitin. There have been several reports of hemolytic anemia or pancytopenia caused by cephalothin, but few, if any, citing the other cephalosporins, particularly cefoxitin. Clinicians should be made aware of the possibility of hematologic toxicities occurring with cefoxitin therapy. Patients should have their erythrocytes, leukocytes, and platelets monitored while on this drug.

The administration of estrogen-induced severe bone marrow depression in 9 of 12 ferrets, independent of sex (male, female) or ovariohysterectomy. Resultant pancytopenia was manifested by subcutaneous petechiae, melena, hematomyelia, pale mucous membranes, pale bone marrow, centrilobular hepatic degeneration, hydrometra, and pyometra. These findings are compatible with the naturally occurring estrus-associated anemia seen in female ferrets.
