An improved understanding of medical problems of alcoholic patients can be gained from commonly encountered laboratory test results. Liver function tests--such as measures of alkaline phosphatase, gamma-glutamyl transpeptidase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase--may provide evidence of altered hepatic activity of different types, such as obstruction and hepatocellular injury. Other test results may indicate impaired hepatic function, such as measurements of albumin, bilirubin, prothrombin time, and blood urea nitrogen. Alterations are also common in electrolytes, blood glucose, magnesium, phosphate, uric acid, and acid-base balance. Disturbances in hematologic function are not infrequent in alcoholic patients, including anemias from many causes, altered granulocyte responses, and thrombocytopenia.

Criteria for the classification of polyarteritis nodosa were developed by comparing 118 patients who had this disease with 689 control patients who had other forms of vasculitis. For the traditional format classification, 10 criteria were selected: weight loss greater than or equal to 4 kg, livedo reticularis, testicular pain or tenderness, myalgias, mononeuropathy or polyneuropathy, diastolic blood pressure greater than 90 mm Hg, elevated blood urea nitrogen or serum creatinine levels, presence of hepatitis B reactants in serum, arteriographic abnormality, and presence of granulocyte or mixed leukocyte infiltrate in an arterial wall on biopsy. The presence of 3 or more of these 10 criteria was associated with a sensitivity of 82.2% and specificity of 86.6%. A classification tree was also constructed, with 6 criteria being selected. Three of these, angiographic abnormality, biopsy-proven granulocyte or mixed leukocyte infiltrate in arterial wall, and neuropathy, were criteria used in the traditional format. The other 3 criteria used in the tree format included the patient's sex, weight loss greater than 6.5 kg, and elevated serum aspartate aminotransferase or alanine aminotransferase levels above the range of normal. The classification tree yielded a sensitivity of 87.3% and a specificity of 89.3%.

cis-Bis-neodecanoato-trans-R,R-1,2-diaminocyclohexaneplatinum++ +(II) (NDDP) is a liposome dependent cisplatin analogue since the liposome carrier is required for its i.v. administration and for its biological activity. A Phase I study of liposome entrapped NDDP (L-NDDP) was performed using a single i.v. injection every 4 weeks. L-NDDP was prepared and characterized at M. D. Anderson Cancer Center. The maximum tolerated dose of L-NDDP was 312.5 mg/m2. The dose-limiting toxicity was myelosuppression, affecting all three blood cell lineages. The granulocyte nadir occurred on days 14-18, and the platelet nadir consistently earlier (days 11-12). The median day of recovery of blood cell counts was day 21 (range, 18-32). Other toxicities included grade 2 nausea and vomiting, fever consisting of a single temperature spike in most patients, grade 1 diarrhea after 60% of courses, and grade 1-2 malaise lasting for 5-10 days after the infusion in 73% of courses. Transient alanine aminotransferase elevations without clinical relevance were common. No signs of renal dysfunction or ototoxicity were observed. One patient with a preexisting peripheral neuropathy showed some progression of the neuropathy after a cumulative dose of 1605 mg/m2. Except for fever and transient liver dysfunction, no liposome related side effects were observed in spite of the high doses of lipid administered. The blood clearance of L-NDDP fits a two-compartment model at lower doses and a single-compartment model at the maximum tolerated dose, suggesting that saturation of the reticuloendothelial organs occurs at the maximum tolerated dose. Two minimal responses were observed. L-NDDP has a toxicity profile similar to that of carboplatin. Phase II studies to address the issue of how the therapeutic index of platinum compounds is affected by liposome entrapment are being planned.

Fundamental and clinical studies of OFLX were performed against the patients with typhoid fever and typhoid carriers. 1) Clinical and bacteriological effects: Eight patients with typhoid fever and 3 typhoid carriers were treated with OFLX. Daily doses of the agent were 900 mg in 5 adult patients, 600 mg in a child patient and 3 adult carriers. In one case of the remaining 2 adult patients, daily doses of the agent changed from 800 mg to 1200 mg and from 900 mg to 1200 mg in the other one. The duration of the treatment was 9, 14 or 21 days. Clinical efficacies of OFLX against the patients proved 4 cases were "excellent", 3 cases were "good" and one case was "poor". The eradication of Salmonella typhi recognized in all cases containing 3 carriers with the exception of the "poor" case. Adverse reactions were observed transiently in 3 patients, such a slight decrease of RBC count, decrease of granulocyte count and elevation of GPT value respectively. 2) Antimicrobial activity: MICs of OFLX against 40 strains of S. typhi were 0.05 micrograms/ml and 0.1 micrograms/ml. The MICs of NFLX, CPFX and T-3262 were almost the same as that of OFLX, and those of ENX, NY-198 and NA were higher than that of OFLX. The peaks of MIC of CP and ABPC, first choice drug against typhoid fever, were 1.56 micrograms/ml and 0.38 micrograms/ml respectively. 3) Serum concentration; Serum concentrations of OFLX were serially measured on 5 patients through the day. The concentrations of the drug were distributed from 0.82 micrograms/ml to 6.34 micrograms/ml at 6.30 a.m. and from 2.52 micrograms/ml to 11.2 micrograms/ml at 9:00 p.m. Those of the day time showed considerable individual differences.

Heparinized venous blood was stored under sterile conditions at different temperatures (4 C, 20 C, 37 C) for various intervals (0-7 days). After storage the granulocytes and lymphocytes were isolated with routine methods. Naphthol AS-D-chloroacetate esterase as a granulocyte marker and acid alpha-naphthyl acetate esterase as a T-lymphocyte marker were identified on smears of the washed cell suspension. Different enzymes were identified in the cell sediment with electrophoresis. Relatively pure lymphocyte suspensions were obtained within the first 24 h. After this time, however, the percentage of these mononuclear cells declined markedly. The percentage of isolated granulocytes varied slightly; there was a marked predominance of granulocytes (more than 70%) at all intervals investigated during the isolation. Cytochemical analysis of the granulocytes and lymphocytes indicated that the decrease in the percentage of enzyme-positive cells depends in each case on the duration of the storage interval. During the first 24 h, only PGM1 and GOTM could be identified in the lymphocyte suspension with horizontal starch gel electrophoresis. The enzymes PGM1, PGM3, PGI, MDH, GOTM, 6-PGD, ADA could always be identified in the granulocyte suspension; AK, FUCA, MEM could be occasionally identified; and GPT and GLO could never be identified.

A combination antibacterial therapy with fosfomycin (FOM) and sulbactam/cefoperazone (SBT/CPZ) was applied to 78 patients with severe infections associated with hematological diseases. In this protocol, FOM was followed by SBT/CPZ and each drug was administered for 1 hour intravenously and consecutively. Among 72 evaluable patients, 43 patients had acute leukemia, myeloblastic or lymphoblastic, 22 had malignant lymphoma, 3 had multiple myeloma, and 4 had other hematological diseases as underlying diseases. Bacterial infections diagnosed were sepsis in 21 patients, suspected sepsis in 47, and other infections in 4. The overall efficacy rate of this treatment was 72.2%, and those for individual infections were 66.7% for sepsis, 74.5% for suspected sepsis, and 75.0% for other infectious diseases. Among 22 bacteria separated from patients with sepsis, 78.6% (11/14 strains) were eradicated by this treatment. This protocol was also effective in 57.1% (8/14) of patients whose granulocyte count was less than 100/mm3 during the course of treatment as well as in 83.3% (15/18) of patients with granulocyte count over 500/mm3. There was no difference in effectiveness between those patients to whom G-CSF was administered and those to whom it was not (17/24, 70.8% vs 35/48, 72.9%). As an adverse reaction, a transient increase of GOT and/or GPT was observed in 2 patients (2.8%). The consecutive administration treatment of FOM and SBT/CPZ is thus an effective and safe regimen for the treatment of patients with hematological diseases complicated by severe infections.

Nitrobenzene (NBZ) is primarily employed as an oxidizing agent in the synthesis of analine and benzene compounds. It produces myelotoxic effects and effects on erythrocytes in both animal models and man. Reported hepatosplenomegaly and effects on the bone marrow are indicators that NBZ may be immunotoxic. In these studies, female B6C3F1 mice were exposed to 30, 100 and 300 mg/kg of NBZ in corn oil by gavage for 14 consecutive days. To assess the immunotoxic potential of NBZ, body and organ weights were determined and selected immunologic and host resistance responses were studied. In these studies, the liver and spleen appeared to be the primary target organs. Both liver and spleen weights were dose dependently increased. Gross histopathologic examinations revealed significant changes in the spleen, consisting of severe congestion of the red pulp areas with erythrocytes and reticulocytes. Serum chemistry profiles showed increases in alanine aminotransferase and aspartate aminotransferase activities, indicating liver toxicity. Hematologic studies showed a decrease in erythrocyte number and a concomitant increase in mean corpuscular hemoglobin and mean corpuscular volume. A dose-dependent increase in peripheral reticulocytes was also seen. DNA synthesis was enhanced, as was the number of formed elements and the number of monocyte/granulocyte stem cells in the bone marrow of treated mice. IgM responses were decreased and the phagocytic activity of macrophages in the liver was dose dependently increased with a concomitant decrease in the activities in the spleen and lung. Other immunological parameters examined were unchanged. Host resistance to microbial or viral infection was not markedly altered by NBZ; however, there were trends towards increased susceptibility where T-cell function contributes to host defense. These data indicate that NBZ-induced hemolysis and liver injury are linked to the observed alterations in bone marrow activity.

We evaluated clinical effects and toxicities of a combination of fosfomycin (FOM) and clavulanic acid/ticarcillin (CVA/TIPC) for treatment of infections complicated with hematological disorders in 61 patients. Fifty-eight patients were evaluable, including 40 with acute leukemia, 13 with malignant lymphoma and 5 with other hematological disorders. Clinical efficacies were excellent in 21 cases, good in 13 cases, fair in 2 cases and poor in 22 cases. The efficacy rate was 58.6% (34 cases/58 cases). This treatment was also effective in 12 of 20 cases in which granulocyte counts were less than 500/microliters through the course of administration. No subjective side effects were observed. Abnormal values in laboratory tests were noted in 1 case. Mild elevations of GOT and GPT were observed. Thus, the combination of FOM and CVA/TIPC is an effective and safe regimen for the treatment of infections in patients complicated with hematological disorders.

We evaluated clinical effects and toxicities of a combination in treatment with cefodizime (CDZM) and minocycline (MINO) for infections complicated with hematological disorders in 67 patients. Fifty-nine patients were evaluable, including 32 with acute leukemia, 15 with malignant lymphoma, and 12 with other hematological disorders. Clinical efficacies were excellent in 17 cases, good in 24 cases, fair in 2 cases, and poor in 16 cases. The efficacy rate was 69.5% (41 cases/59 cases). This treatment was also effective in 8 of 12 cases in which granulocyte counts were less than 500/microliter through the course of administration. No subjective side effects were observed. Abnormal values in laboratory tests were noted in 5 cases. Mild elevations of GOT, GPT, Al-P and bilirubin were observed, but none was serious. Thus, the combination of CDZM and MINO is an effective and safe regimen for the treatment of infections in patients complicated with hematological disorders.

A 67-year-old woman was admitted to our hospital with a fever. She had been experiencing arthralgia for about one month. On admission, she had a fever of 38.5 degrees C, was anemic and was experiencing tenderness in the joints of both hands, elbows and feet. Laboratory data revealed proteinuria, urinary cylinders, pancytopenia (WBC 900/mm3, Hb 9.5 g/dl, Plt 7.8 x 10(4)/mm3), liver dysfunction (GOT 414 IU/l, GPT 140 IU/l), and hyper-gamma globulinemia. Antibiotics and granulocyte-colony stimulating factor were administered intravenously. Bone marrow aspiration was unsuccessful, but a bone marrow biopsy revealed bone marrow fibrosis. Immunological examinations were positive for antinuclear antibodies, anti-deoxyribonucleic acid (DNA) antibodies, anti-double stranded anti- DNA antibodies, as well as a decreased level of serum complement and an increased level of serum immune complexes. Tests for viral antigens and antibodies known to cause hepatitis were negative. Based on these findings, a diagnosis of SLE accompanied by liver dysfunction and bone marrow fibrosis was made. Steroid pulse therapy was initiated, but her liver function deteriorated on the first day of steroid therapy, and she died three days later. SLE accompanied by myelofibrosis is extremely rare, and only 17 and cases have been reported to date. Among these reports, the present case is the second oldest subject and the first SLE patient to suffer from both myelofibrosis and severe liver dysfunction.
