[Pulmonary tuberculosis in patients with hematological malignancies].

INTRODUCTION: Lung tuberculosis, resulting from decreased cellular immunity, is associated with malignancies and is most frequently seen in Hodgkin's disease, leukemia and T-cell lymphoma. MATERIAL AND METHODS: In the period 1995-2000, 20 patients (pts) with lung tuberculosis and hematological malignancies were analyzed, out of whom 7 (35%) were females, with mean age of 56 years, and 13 (65%) were males, with mean age of 55 years. RESULTS AND DISCUSSION: Among the affected, 8 (40%) patients had Non-Hodgkin's lymphoma, 5 (25%) suffered from chronic lymphocytic leukemia, 4 (2%) had Hodgkin's disease, 1 (5%) manifested a myelodysplastic syndrome, 1 (5%) multiple myeloma and 1 (5%) had chronic myeloid leukemia. The average time from completing a specific cancer therapy and development of tuberculous infection was 20 months, except in 3 cases who had a hematological malignancy and lung tuberculosis at the time of initial diagnosis. The diagnosis was made on the basis of positive findings of sputum smear in 15 (75%) pts, by bronchological examination and sputum analysis in 3 (15%) pts, lymph node biopsy and sputum analysis in 1 (5%) case, pleural biopsy in 1 (5%) patient, and finally confirmed by culture in 19 (95%) pts. Radiological examination revealed fibrocaseous tuberculosis in 14 (70%) pts, out of whom 12 with bilateral and 2 with unilateral changes, 3 (15%) manifested miliary tuberculosis, and 3 (15%) had pleural effusion and tuberculosis. CONCLUSION: Successful outcome was achieved in 18 (90%) pts, while lethal outcome was reported in 2 (10%) cases with miliary pulmonary tuberculosis.

Palifermin (Kepivance) for the treatment of oral mucositis in patients with hematologic malignancies requiring hematopoietic stem cell support.

OBJECTIVE: To provide a comprehensive review of the clinical use of the recombinant biological agent, palifermin, with particular reference to its use in its approved indication, oral mucositis resulting from high dose chemotherapy and radiation in patients with hematologic malignancies requiring hematopoietic stem cell support. DATA SOURCES: A MEDLINE search was conducted using the terms 'palifermin' and 'Kepivance.' All data available from MEDLINE were reviewed. The reference lists from retrieved articles were reviewed and other relevant papers were identified. DATA SUMMARY: Keratinocyte growth factor (KGF) is a growth factor that acts specifically on epithelial cells playing a role in proliferation, migration, and morphogenesis. Palifermin is a recombinant human form of KGF. Because of its ability to cause proliferation of the oral mucosa and to protect against mucosal injury, palifermin is a treatment option for patients who are at high risk for oral mucositis, specifically patients with hematological malignancies receiving stem cell transplantation (SCT). In a phase III study of these patients, the overall incidence of World Health Organization (WHO) grade 3 or 4 oral mucositis was significantly reduced in the palifermin group (palifermin = 63% versus placebo = 98%, P < 0.001). Among the patients who experienced WHO grade 3 or 4 oral mucositis the average duration of this grade of mucositis in the palifermin group was six days compared with nine days in the placebo group (P < 0.001). Common adverse effects of palifermin include pruritus, erythema, mouth and tongue disorders, and taste alterations.

[Therapeutic effect of ticarcillin against severe infection in patients with hematologic malignancy (author's transl)].

Seventy patients with severe infection accompanying hematologic disorders including leukemia and lymphoma were treated with ticarcillin in combination with aminoglycosides and/or cephem derivatives. Of the 58 patients in whom the efficacy could be evaluated, 17 (29%) responded markedly and 22 (38%) moderately, the effective rate being 67%. Side effects attributable to the treatment were noted: rash in 2, fever and rash in 1, vascular pain in 2 (5 and 7 years of age). Renal and hepatic functions were abnormal in 4 each. However, these abnormal findings were not attributed to ticarcillin. These results indicate that ticarcillin is an effective and safe antibiotic for the treatment of severe infection accompanying hematologic malignancy when used in combination with aminoglycosides and/or cephem derivatives.

Platelet transfusions in advanced hematological malignancies: a position paper.

Treatment of patients with advanced-stage hematological malignancies (HM) includes frequent transfusions. Given present limited hospital budgets, administrative pressure is increasing on hematology services to limit the cost of these transfusions. An expert multidisciplinary panel involved in hematology formed a working party to draw up a series of proposals, including definitions of advanced stage disease and the indications for platelet transfusion. Their proposals included: (a) Platelet transfusions are indicated for the treatment of bleeding caused by low platelet counts; (b) Patients should receive full information, including the basic criteria for platelet transfusion; (c) Doctors should be trained to assess whether or not platelet transfusions are urgently required; and (d) The practice of home transfusions should be encouraged.

Impact of prophylactic donor leukocyte infusions on mixed chimerism, graft-versus-host disease, and antitumor response in patients with advanced hematologic malignancies treated with nonmyeloablative conditioning and allogeneic bone marrow transplantation.

In an attempt to capture graft-versus-tumor effects without graft-versus-host disease (GVHD), the authors initiated a trial of nonmyeloablative allogeneic bone marrow transplantation (BMT) in patients with advanced hematologic malignancies, with the majority of patients having chemotherapy-refractory disease. Forty-two patients received an HLA-matched related donor BMT after a cyclophosphamide and antithymocyte globulin-based conditioning that also included thymic irradiation for patients who had not received prior mediastinal radiotherapy. Prophylactic donor leukocyte infusion (pDLI) at a dose of 1 x 10(7) CD3(+) cells per kilogram were given beginning 5 weeks post-BMT to 16 patients with mixed chimerism (MC) but without GVHD, whereas 26 patients did not receive pDLI, either because of GVHD or early relapse. Twelve of 16 patients (75%) receiving pDLI had T cell chimerism at the time of pDLI >/=40%. These patients, by day 100 post-BMT, either converted to full donor chimerism (FDC) (n = 10) or had an increase in or stable donor chimerism (n = 2) after pDLI. Four of 4 patients whose T cell chimerism was </=20% at the time of pDLI, lost the graft. In contrast, only 5 of 18 evaluable patients (28%) not receiving a pDLI converted to FDC by day 100 post-BMT, 7 maintained MC, and 10 of an evaluable 22 lost the graft. Patients who had undergone a previous autologous stem cell transplant had a higher rate of conversion to FDC (69% v 31%) and higher incidence of GVHD (69% v 34%) compared with those who did not have a previous autologous SCT. Eleven of 16 patients (69%) who received a pDLI achieved a remission with 50% 1-year progression-free survival rate and 44% 3-year overall survival rate. Nineteen of 42 patients (45%) had >/=grade II acute GVHD, including 12 after BMT and 7 after pDLI. Approximately one third of patients, after having initial MC, eventually lost their donor graft. The authors conclude that (1) pDLI has the potential to convert MC to FDC; (2) sustained remissions can be achieved in patients with chemorefractory hematologic malignancies who receive a pDLI, albeit with a significant risk of acute GVHD; and (3) the degree of donor T cell chimerism at the time of pDLI is predictive of the fate of MC, ie, donor T cell chimerism >/=40% or </=20% at the time of pDLI correlates with conversion of MC or loss of the graft, respectively.

Compound GW506U78 in refractory hematologic malignancies: relationship between cellular pharmacokinetics and clinical response.

PURPOSE: In vitro investigations with arabinosylguanine (ara-G) demonstrated potent cytotoxicity to T-lymphoblastoid cell lines. The goals of the present study were to evaluate GW506U78, a prodrug of ara-G, against human hematologic malignancies and to determine its pharmacokinetics in plasma and cells. PATIENTS AND METHODS: During a phase I multicenter trial of GW506U78, 26 patients were treated at M.D. Anderson Cancer Center (MDACC). Daily doses between 20 and 60 mg/kg were administered for 5 days. Parallel plasma and cellular pharmacokinetic studies were conducted. RESULTS: Complete (n=5) or partial remission (n=5) was achieved in T-cell acute lymphoblastic leukemia (T-ALL), T-lymphoid blast crisis, T-lymphoma, and B-cell chronic lymphocytic leukemia (B-CLL) (n=13). In contrast, patients with B-ALL, B-lymphoma, acute myelogenous leukemia (AMI), or T-CLL did not respond. Peak plasma concentrations of GW506U78 and ara-G were dose-dependent. The elimination of GW506U78 (half-life [t1/2]=17 minutes) was faster than the elimination of ara-G (t1/2=3.7 hours). Median peak concentrations of ara-GTP were 23, 42, 85, and 93 micromol/L at 20, 30, 40, and 60 mg/kg, respectively. T-lymphoblasts accumulated significantly (P=.0008) higher peak arabinsylguanosine triphosphate (ara-GTP) (median, 140 micromol/L; n=7) compared with other diagnoses (median, 50 micromol/L; n=9) and normal mononuclear cells (n=3). The ara-GTP elimination was slow in all diagnoses (median, > 24 hours). Responders accumulated significantly (P=.0005) higher levels of ara-GTP (median, 157 micromol/L) compared with patients who failed to respond (median, 44 micromol/L). CONCLUSION: GW506U78 is an effective prodrug and a potent agent for hematologic malignancies with major efficacy in T-cell diseases. The pharmacokinetics of ara-GTP in leukemia cells are strongly correlated with clinical responses to GW506U78.

Severe liver disease is caused by HBV rather than HCV in children with hematological malignancies.

UNLABELLED: Patients receiving chemotherapy experience exacerbations of chronic hepatitis B (HBV) or hepatitis C (HCV) viral infections. We examined the pattern of liver disease induced by these infections in 92 children and adolescents with elevated transaminases (median age: 9 years). This included 76 with hematological malignancies (55 ALL, 15 NHL and six Hodgkin's disease) and 16 with thalassemia major. Liver disease was graded: A--occasional hypertransaminemia, B--persistent hypertransaminemia, C--severe hepatitis without encephalopathy, D--fulminant hepatic failure (FHF) and death. Screening included HBsAg, anti-HCV antibody, HBV-DNA and HCV-RNA: 26 had liver biopsies. A total of 60 (79%) patients with malignancies were HBsAg and/or HBV-DNA(+)(genotype D-E) and 47 (62%) were anti-HCV and/or HCV-RNA(+); 33 were coinfected with HBV and HCV. Grade A (n=24) included 16 with HCV and 12 with HBV (six coinfected); 18 with HBV and 11 with HCV (10 coinfected) were graded B (n=22). All grade C (n=25) had HBV with 16 HCV coinfected. FHF and death occurred in five HBV-DNA(+) patients, in four within a month of i.v. methotrexate. Patterns C and D were associated with HBsAg and HBV-DNA (P=0.001 and P<0.001, respectively). In all, 70% of HBV-infected children suffered chemotherapy-associated flares. None of the thalassemics had severe hepatitis exacerbations; 94% had HCV markers with none HBV-DNA(+). One died of progressive cirrhosis. CONCLUSIONS: Children with hematological malignancies have worse liver disease when associated with chronic HBV. FHF occurred in HBsAg/HBV-DNA(+) children following i.v. methotrexate. Early recognition of hepatic dysfunction in HBV carriers is essential in order to reduce incidence of life-threatening complications.

Invasive pulmonary aspergillosis in patients with hematologic malignancies: survival and prognostic factors.

BACKGROUND AND OBJECTIVES: Despite improvements made in its early diagnosis and effective treatment, invasive pulmonary aspergillosis (IPA) remains a devastating opportunistic infection. In this retrospective study we have reviewed all consecutive cases of IPA diagnosed in adult patients with hematologic malignancies in our center from 1995 to 2000 to determine survival and prognostic factors. DESIGN AND METHODS: Forty-one patients were included in the study. Ante-mortem classification of cases of IPA were: 4 definite, 10 highly probable, 19 probable and 8 possible cases; all these last eight patients were later upgraded to definite IPA at post-mortem examination. Clinical charts were reviewed and factors possibly affecting the outcome of IPA were analyzed. RESULTS: All but two patients received chemotherapy and/or immunosuppresive therapy before the onset of IPA (conventional chemotherapy = 24, allogeneic stem cell transplantation [SCT] = 12, autologous SCT = 3). At IPA diagnosis 28 patients were neutropenic (< 0.5 x 10(9)/L) for a median of 25 days (range 7-135), and 10 allogeneic SCT patients were receiving corticosteroids for graft-versus-host-disease. All but two patients received antifungal treatment for IPA. The median delay from diagnosis to start of therapy was two days (range 0-20). The median follow-up after the first symptom or sign of IPA was 42 days with a maximum follow-up of 61 months. The actuarial 4-month infection-free survival was 40% (95% CI 25% to 55%). Thirty-three patients died during follow-up and IPA was implicated in the patients' death in 24 cases (75%). In multivariate analysis prolonged survival was associated with recovery of neutropenia during treatment (p = 0.001) and not having received an allogeneic SCT (p = 0.003). INTERPRETATION AND CONCLUSIONS: Despite prompt initiation of antifungal therapy, survival of patients with a hematologic malignancy and IPA is currently low. Perhaps the introduction of more sensitive diagnostic methods will allow the onset of intensive therapy prior to the appearance of more advanced clinical symptoms and/or radiological signs, and the time will come to test whether earlier and more intensive therapy will improve survival.

Aspergillus pneumonia in hematologic malignancy. Improvements in diagnosis and therapy.

Pulmonary aspergillosis in patients with leukemia or lymphoma is usually a fatal infection. However, difficulty in obtaining a premortem diagnosis has often prevented an adequate trial of anti-fungal chemotherapy. In this report, nine cases of aspergillus pneumonia in patients with hematologic malignancy were diagnosed during a one-year period. Five of nine patients had a premortem diagnosis (56%) and eight of nine (89%) received a premortem trial of amphotericin B. Two of nine patients survived infection, including one patient with prolonged neutropenia. Better diagnostic methods and wider use of antifungal chemotherapy may improve prognosis for aspergillus infection in patients with hematologic malignancy.

Pathologic rupture of the spleen in hematologic malignancies: two additional cases.

Pathologic rupture of the spleen in hematologic malignancies is rare. We present two cases of splenic rupture which occurred in a man with a secondary high-grade non-Hodgkin's lymphoma and a woman with chronic lymphocytic leukemia (CLL). In a review of the literature, we have been able to identify 136 cases of pathologic splenic rupture since 1861; 34% have occurred in acute leukemias, 34% in non-Hodgkin's lymphomas, and 18% in chronic myelogenous leukemia (CML). We find a male-to-female ratio of 3:1, with considerable differences for the specific diseases encountered. Pathologic rupture of the spleen has happened almost exclusively in adults and the ruptured spleens are generally moderately to severely enlarged. It seems that, apart from splenic infiltration by a hematologic disease, splenic infarcts and coagulation disorders (which have previously been advanced as the most important pathophysiologic factors leading to rupture), male sex, adulthood, severe splenomegaly, and cytoreductive chemotherapy may increase the risk for pathologic splenic rupture. We briefly discuss symptoms preceding the event, diagnostic possibilities, and the outcome with operative and conservative approaches.

The value of an immunoenzymatic test (enzyme-linked immunosorbent assay) for the diagnosis of strongyloidiasis in patients immunosuppressed by hematologic malignancies.

The diagnosis of strongyloidiasis relies upon the identification of the parasite in stool samples. In 1981, a serologic assay was developed, which was useful in the diagnosis of strongyloidiasis in the immunocompetent host. In the present study, we evaluated the enzyme-linked immunosorbent assay (ELISA) in patients with hematologic malignancies. Between April 1995 and December 1998, sera from 164 consecutive patients were tested for the presence of IgG antibody to Strongyloides stercoralis. Patient was considered uninfected after at least three negative stool examinations. The prevalence of strongyloidiasis was 13%. The underlying diseases were acute leukemia in 21% and lymphoma in 52% of the patients. The majority of the patients were receiving chemotherapy (93%) and steroids (76%). The sensitivity, specificity, and positive and negative predictive values were 68%, 89%, 48%, and 95%, respectively. The ELISA may be an excellent assay to rule out the diagnosis of strongyloidiasis in patients with hematologic malignancies.

A phase I study of a new cisplatin derivative for hematologic malignancies.

DWA2114R (DWA) is a new derivative of platin compounds that is currently being used in Phase II studies of solid tumors in Japan. The dose-limiting factor is myelotoxicity with mild extramedullary toxicity. This Phase I study consisted of adult patients with relapsed hematologic malignancies. Eight patients received a total of 15 treatment courses of DWA. The starting dose was 800 mg/m2 over 24 hours by continuous infusion. The dose was first increased to 1200 mg/m2 and then to 1600 mg/m2. Clinical toxicity and urinary excretion studies of DWA suggested that 1200 mg/m2/d for successive days would be the best type of administration. When 1200 mg/m2/d was given for 5 days, Grade 2 to 3 diarrhea and nausea and vomiting were encountered requiring parenteral fluids and nutritional support. This suggested that the dose-limiting factor with this schedule was gastrointestinal toxicity. Myelotoxicity was severe, as expected, but tolerable. One of the five patients with acute nonlymphocytic leukemia (ANLL) entered into complete remission and one patient with chronic myelogenous leukemia (CML) in crisis returned to the chronic phase. A Phase II trial of DWA is warranted for hematologic malignancies, especially in myeloid diseases.

P-glycoprotein expression by technetium-99m-MIBI scintigraphy in hematologic malignancy.

UNLABELLED: Our aim was to ascertain the relationship between the degree of 99mTc-MIBI uptake and the level of p-glycoprotein (Pgp) expression determined by flow cytometry and reverse transcription-polymerase chain reaction (RT-PCR) techniques in patients with hematologic malignancy. METHODS: A total of 21 samples (19 patients) were evaluated. Two patients had repeat studies after therapy. Thirteen samples were studied at the time of initial diagnosis and 8 during relapse after therapy. After MIBI imaging, either bone marrow aspiration or peripheral blood was obtained for flow cytometric and RT-PCR analyses. Flow cytometry was performed using two different antibodies. After the injection of 555 MBq MIBI, whole-body and pelvic spot images were acquired using a dual-head gamma camera. The uptake in the bone marrow was evaluated against the background (adjacent soft tissue) by both qualitative (scoring system) and quantitative (tm/bkg ratios) analyses. RESULTS: For flow cytometry, the limit for Pgp overexpression was set at >15% Pgp-positive mononuclear bone marrow or peripheral blood cells. There was an inverse correlation between the levels of Pgp and MIBI imaging using both the qualitative (scoring system) and quantitative (tm/bkg ratios) analyses (p = 0.022). Mean values were statistically different between Pgp+ and Pgp- groups for both qualitative and quantitative analyses (p = 0.009 and 0.024, respectively). For RT-PCR, there was statistical support toward a difference in the mean values between Pgp+ and Pgp- groups by qualitative analysis (p = 0.061); however, no statistical difference was found between these two groups by quantitative analysis (p = 0.179). CONCLUSION: Based on the strong correlation between the imaging and flow cytometry and a statistical support toward the correlation between the imaging and RT-PCR, MIBI imaging may be used for the in vivo detection of Pgp in patients with hematologic malignancy.

Update on the role of epoetin alfa in hematologic malignancies and myelodysplastic syndromes.

Anemia is a frequent complication in hematologic malignancies. In advanced stages of chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and myeloma, anemia usually develops in parallel with marrow involvement. However, anemia may occur in the absence of overt infiltration of bone marrow by malignant cells. When all other causes of anemia (such as chronic bleeding, vitamin deficiency, hemolysis, and pure red blood cell aplasia) are eliminated, anemia can be related to "anemia of chronic disorders." Myelodysplastic syndromes are characterized by cytopenias. Anemia is very frequent, and nearly 90% of patients present with anemia during the evolution of the disease. In this disorder, erythroid progenitors are defective for their proliferation and maturation, as shown by in vitro culture techniques. Moreover, these patients often have a high endogenous serum erythropoietin level. The rationale for treating these patients with epoetin alfa is the possibility of overcoming the defective proliferation by pharmacologic doses of epoetin alfa. The response rate was rather low with epoetin alfa alone. Combinations with earlier-acting cytokines, such as recombinant human granulocyte colony-stimulating factor, have been tested in an attempt to improve response rates.

Role of interleukin-2 in human hematological malignancies.

Clinical studies with Interleukin-2 (IL-2) in human hematologic malignancies were initiated in the late 1980s. Based on clinical studies on various solid tumors, and laboratory research on hematopoietic cells, IL-2 was shown to be effective in 150 acute myeloid leukemia (AML) patients mainly for maintenance therapy in first complete remission, or with residual blast cells in the marrow. IL-2 has also been shown to be effective in remission induction in 10 patients with chronic myeloid leukemia (CML). The role of IL-2 in lymphoma patients remains to be established. IL-2 alone or in combination with Interferon-alpha, may intensify remission and prolong disease-free survival when given post autologous bone marrow transplantation (BMT) to patients with lymphoma and myeloid leukemia, and to a lesser degree, to patients with acute lymphatic leukemia (ALL). IL-2 in combination with HLA-matched or mismatched peripheral blood lymphocytes was also used post autologous BMT in preliminary studies. IL-2 was administered with or without peripheral blood lymphocytes, for prevention of relapse post T-cell-depleted allogeneic BMT in CML, ALL and AML, with encouraging results. The same strategy was shown to be effective in the reinduction of remission in patients with CML, who relapsed post BMT.

Surgical interventions in patients with hematologic malignancies.

While surgery is not a part of treatment of hematological malignancies a significant number of patients suffering from such diseases need to undergo surgical interventions. These may comprise of very minor procedures such port implantation, however, already the indication for appendicectomy could be a difficult scenario being influenced by the underlying disease and side effects of the treatment. Often septic foci need to be cleared prior to start of systemic treatment. Out of the really major problems, the surgical resection of aspergillomas represent a demanding task accompanied by significant morbidity and mortality. Emergency situations sometimes are induced by treatment such as necrotizing enterocolitis but sometimes are mimicked by drug-induced abdominal symptoms. An experienced team of surgical and medical oncologists is required for successful management. As the number of long-term surviving patients increases, secondary problems as aseptic bone necrosis need to be addressed and adequately handled. Even at this stage it might be difficult to assess the patients risk for open-heart surgery adequately. This group of patients if scheduled for any operative intervention needs to undergo a very careful selection process and perfect perioperative management to make sure that the result of surgery are excellent and do not compromise further medical treatment of the underlying disease.

[Doxorubicin-induced myocardial damage in elderly patients with hematologic malignancies].

Cardiac function was evaluated in 53 elderly patients with hematologic malignancies who were being treated with doxorubicin (DXR). The left ventricular ejection fraction was measured by radionuclide angiocardiography, the washout rate by 123I-MIBG myocardial SPECT, the extent and severity scores by 123I-BMIPP myocardial SPECT, and the frequency of premature ventricular contractions by Holter electrocardiography. 1) In some patients, both the washout rate and the extent and severity scores were abnormally high before treatment. 2) Because the washout rate correlated with the total dose of DXR, it may be an early indicator of cardiac sympathetic nervous dysfunction. 3) The left ventricular ejection fraction correlated with the extent and severity scores, but not with the washout rate or with the frequency of premature ventricular contractions. 4) The washout rate correlated with the frequency of premature ventricular contractions. These data show that elderly patients had abnormal cardiac function even before treatment with DXR; that cardiac sympathetic dysfunction and cardiac mitochondrial dysfunction developed at total DXR doses of 250 to 300 mg/m2 or higher; and that the left ventricular ejection fraction was less than or equal to 50% in many patients. Consequently, when DXR is used to treat elderly patients, multimodal evaluation of cardiac function is necessary to detect cardiotoxicity and to determine the optimal total dose and the optimal dosage.

Amphotericin B lipid complex (ABLC) for the treatment of confirmed or presumed fungal infections in immunocompromised patients with hematologic malignancies.

Sixty-four adult patients (median age 43) with hematologic malignancies who were immunocompromised after allogeneic (n = 23) or autologous (n = 9) blood/marrow transplantation, or chemotherapy (n = 32) received 68 courses of amphotericin B lipid complex (ABLC, Abelcet) at the daily dose of 5 mg/kg for presumed (n = 52) or proven (n = 16) fungal infection. The major indications for ABLC were failure of previous antifungal therapy and/or renal dysfunction. Fifty-three treatment courses in 49 patients comprising 4-58 doses (median 10) were considered evaluable. Fourteen courses administered for confirmed infections resulted in nine complete and one partial responses, and four failures (71% response). Thirty-nine empiric courses resulted in 18 complete and six partial responses, and 14 failures (64% response). The overall response rate was 66%. Five of seven evaluable patients with aspergillus pneumonia responded. Response rates were comparable for chemotherapy, autograft and allograft recipients. The change in serum creatinine from the beginning to the end of therapy was -284 to +277 mumol/l (median +24). The creatinine doubled during seven evaluable courses of therapy, five of which were associated with concomitant nephrotoxic therapy. Nephrotoxicity was comparable for transplant and chemotherapy patients. Renal dysfunction necessitated discontinuation of ABLC in only four patients. These data suggest that ABLC is effective in presumed or confirmed fungal infections in immunocompromised patients after transplantation or chemotherapy.
