Two hundred forty children with acute leukaemia in remission for at least 1 year were immunized with live attenuated varicella vaccine. All were susceptible to varicella before immunization. There was a seroconversion to varicella-zoster virus in approximately 85% after 1 dose, and in 97% after 2 doses. The major side effect was mild to moderate rash, seen mainly in children with maintenance chemotherapy suspended for 1 week before and 1 week after vaccination. Vaccinees with rash were at some risk (10%) to transmit vaccine virus to varicella susceptibles with whom they had close contact. Twenty-nine vaccinees were subsequently exposed to varicella in their households. The attack rate of clinical varicella in these vaccinees was 21%, which is significantly lower than the 80%-90% attack rate occurring in varicella susceptibles after household exposure. All these breakthrough cases of varicella were mild, even in leukaemics receiving chemotherapy. Varicella vaccine was approximately 80% effective in preventing clinical varicella in children with leukaemia and completely effective in preventing severe varicella in this high-risk group.

Nineteen children with acute lymphoblastic leukaemia or other malignancies, aged 3-13 years, with negative histories of varicella-zoster virus (VZV) and of whom 5 were still on regular maintenance chemotherapy, were vaccinated with the Oka-strain varicella vaccine. Mild systemic reactions, involving low-grade fever of a few days duration, were recorded in 4 of the vaccinees. Two of them also developed an extremely sparse rash. A mild local reaction at the vaccination site was observed in 1 child. Conversion rates for circulating VZV antibody, measured at 4-6 weeks and 4-6 months after vaccination using an indirect immunofluorescence test, were 8/12 (67%) and 5/9 (56%), respectively. Markedly lower antibody conversion rates of 5/18 (28%) and 5/14 (36%) were found by means of the enzyme-linked immunosorbent assay method. Corresponding conversion rates for cell-mediated immunity against VZV, determined using a specific lymphocyte stimulation technique, were 9/17 (52%) and 12/14 (86%), respectively.

Live attenuated varicella vaccine has been administered to 307 children with leukemia in remission and to 86 healthy adults. The vaccine was well tolerated and immunogenic. The major side effect in leukemic children receiving maintenance chemotherapy was development of a vaccine-associated rash. Vaccinees in whom a rash developed were potentially somewhat infectious to others about 1 month after immunization. Vaccination was not associated with an increase in the incidence of herpes zoster or in relapse of leukemia. Vaccination provided excellent protection against severe varicella. It was associated with a significant decrease in the attack rate of chickenpox following an intimate exposure to varicella-zoster virus, conferring about 80% protection in leukemic children. The cases of breakthrough varicella that occurred were mild. Thus, the vaccine may either prevent or modify varicella in high-risk individuals. It may also have use for prevention of nosocomial varicella.

Immunoblastic lymphadenopathy (IBL)-like T-cell lymphoma is a distinct peripheral T-cell lymphoma, which closely resembles angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) and/or IBL, but is characterized by focal or sheet-like proliferation of immunoblasts and pale cells of T-cell nature. In this report, 36 patients with IBL-like T-cell lymphoma were analyzed. The disease is clinically characterized by generalized lymph node swelling, hepatosplenomegaly, fever, skin rash, polyclonal hypergammaglobulinemia, marked male predominance, predilection for the elderly, and poor prognosis. There was no association with human T-cell leukemia virus type I or human immunodeficiency virus. IBL-like T-cell lymphoma may be divided into two categories (CD4+ type and CD8+ type) by surface marker analysis. It can also be divided into three categories on the basis of the histologic findings of distribution of morphologically recognizable tumor cells: nine cases of "inconspicuous type," six cases of "patchy type," and 21 cases of "diffuse type." Two cases of "inconspicuous type" converted later to "diffuse type." DNA hybridization analyses in the ten recent cases revealed that three of four "inconspicuous types" and five of six "diffuse types" showed clonal rearrangement of T-cell receptor-beta chain gene without rearrangement of immunoglobulin heavy chain gene, providing strong evidence for clonal proliferation of T cells.

Over a two year period 174 evaluable episodes of fever in neutropenic patients were treated in a randomized study comparing four beta-lactam antibiotics, each given in combination with netilmicin. Exclusions included episodes due to viral or fungal infection, and trial violations. Most patients were receiving treatment for leukaemia, including 18% undergoing bone marrow transplantation. The overall response rate (EORTC criteria) was 66%, ranging from 56% for cefoperazone to 76% for mezlocillin. Microbial documentation was obtained in 31% of episodes; Gram-positive isolates were most frequent but Pseudomonas aeruginosa was found in 18 patients. In patients with microbiologically documented infection 70% improved, overall--from 40% with cefoperazone to 80% with piperacillin (P less than 0.05). Nephrotoxicity was seen in 6.7% and was associated with severe documented sepsis. Hypokalaemia was seen in 29% and was most marked in patients receiving ticarcillin. Rashes occurred in 6.6% overall, with no difference between the groups. Ototoxicity, shown by serial audiograms, was seen in 4.7% of patients. No evidence of vestibular dysfunction was seen in 62 patients studied. Of thirteen deaths due to the primary infection, seven were caused by Ps. aeruginosa and five by fungi.

Thirty-one patients with hairy-cell leukemia were treated with 2'-deoxycoformycin (DCF) in a National Cancer Institute of Canada multicenter trial. The DCF was administered in a cycle (4 mg/m2 iv weekly X 3), which was repeated every 8 weeks. Following a complete remission, consolidation was done with two further cycles of DCF. Of 28 patients evaluable for response, 25 obtained a complete remission; 3 had a partial response. To date there has been only one relapse; the median time with no therapy was 429.5 days (range 99-743 days). Toxicity was moderate and included nausea and vomiting, lethargy, and skin rash; with the first cycle of treatment, neutropenia and an increased incidence of fever or infection were also observed. We conclude that low-dose DCF is highly effective in treating hairy-cell leukemia.

Although leukaemic infiltration of the skin commonly occurs in acute monoblastic leukaemia, the association with chronic myelomonocytic leukaemia (CMML) has only been described recently. We confirm the association and report histologically proven monocytic infiltration of the skin in four patients with CMML. This did not herald a more aggressive phase of the disease as previously suggested. Treatment of the rash with low dose cytarabine or etoposide was effective but razoxane produced no benefit. Superficial radiotherapy was useful to control pruritus in one patient.

Seventy-one patients with severe infections associated with hematologic disorders including leukemia, lymphoma and aplastic anemia were treated with ceftizoxime (CZX) in daily doses of 4-6 g for an average of 20.1 days. Infections associated with hematologic disorders consisted of sepsis and pneumonia, and most of the causative organisms appeared to be Gram-negative bacteria. Of the 64 patients who completed the trial, excellent response was observed in 16 and moderate response in 26. The rate of clinical effectiveness was 65.6%. Side effects observed during the treatment included skin rash in only 1 patient, and hepatic disorders in 6 patients. However, the relationship between CZX and these abnormal findings was not established. These results indicate that CZX is a therapeutically effective and safe antibiotic for the treatment of severe infections associated with hematologic disorders.

Ninety nine patients with leukemia and/or related disorders were treated with cefmenoxime (CMX). Among them, 77 patients had severe infections, while other 22 patients did not suffer from infection, but it was expected that they would fall into serious conditions if they were infected. Sixty of the 77 patients who had severe infection were used in the evaluation of effectiveness. The remaining 17 patients were not evaluated because they were subjected to combined treatments of CMX and other therapeutic agents such as other antibiotics, gamma-globulin or interferon. Excellent responses were found in 26 (43.3%) patients and good responses in 12 (20.0%) patients. In total, the rate of effectiveness was 63.3%. Nineteen of the 22 patients who were treated prophylactically with CMX were used in the evaluation of effectiveness, while 3 patients were excluded from the evaluation because peripheral neutrophils were counted to be more than 1,000/mm3 before CMX was administrated, although these 3 patients were used in the final evaluation to examine side effects. In the prophylactic treatment, the rate of effectiveness was 89.5%. The side effects were seen in 4 patients (4/82:4.9%). A different symptom was identified in each patient. These symptoms were skin rash, mild nausea, mild diarrhea and slight elevation of serum bilirubin. Prompt improvements of these symptoms occurred as soon as CMX administration was stopped. These results show that CMX is a therapeutically effective and safe antibiotics for the treatment of severe infections or for the prophylaxis of infections in patients associated with leukemia and/or related disorders.

Timentin (5.2 g tds) and tobramycin (40 mg tds) were administered to 51 patients (22 male, 29 female, age range 17-72, mean age 40.4) with acute leukaemia, chronic myeloid leukaemia in blastic crisis, severe aplastic anaemia and acute agranulocytopenia. All patients had neutropenia (PMN less than 1000/mm3) and fever (greater than 38 degrees C). Febrile episodes consisted of 22 proved septicaemias due to Gram-positive organisms (Staphylococcus aureus, S. epidermidis, enterococcus) in 11 cases and to Gram-negative organisms (Escherichia coli, Pseudomonas aeruginosa, Alkaligenes faecalis, Serratia marcescens, Klebsiella pneumoniae) in 10 cases. One patient had a polymicrobial infection (P. aeruginosa, S. aureus, non-haemolytic streptococcus). Twenty-nine infections were diagnosed only clinically. The mean duration of treatment was 11.1 days (range 4-20 days). Eighty-seven per cent of evaluable febrile episodes improved. Among 11 infections due to Gram-positive cocci, eight (72%) resolved, and in nine (90%) of ten cases due to Gram-negative bacilli success was obtained. The polymicrobial infection also resolved. In only four patients were mild side effects seen, e.g. exanthema, pruritus, phlebitis: renal toxicity was not observed. These data suggest that the combination of Timentin and tobramycin is an effective and safe empirical antibiotic regimen in febrile neutropenic patients.
