Successful treatment of severe hemorrhagic cystitis after hemopoietic cell transplantation by selective embolization of the vesical arteries.

Hemorrhagic cystitis (HC) is a common and sometimes life-threatening complication of hemopoietic cell transplantation (HCT) occurring in 7-52% of transplant recipients. In this setting it is usually either related to the use of cyclophosphamide or to a viral infection (BK, JC viruses and adenovirus type 11). Treatment is based on hyperhydration, platelet and blood-cell transfusions, bladder irrigation and pain management. Where these measures have failed to control HC, numerous therapeutic approaches including surgery have been tried with poor success. We report two HCT patients with severe HC successfully treated with selective embolization of the vesical arteries.

Serial quantification of lymphoid and myeloid mixed chimerism using multiplex PCR amplification of short tandem repeat-markers predicts graft rejection and relapse, respectively, after allogeneic transplantation of CD34+ selected cells from peripheral blood.

We used multiplex amplification of nine microsatellite sequences (PCR-STR) to analyse chimerism in pure populations of T cells and neutrophils from peripheral blood from 40 patients submitted to an allogeneic transplant, 22 having received a T-cell depleted (TCD) peripheral blood graft by means of CD34(+) selection (allo-PBT/CD34(+)), and 18, an unmodified graft (allo-SCT; 13 allogeneic bone marrow transplants and five allo-PBT). T-cell mixed chimerism (TcMC) was observed in 16 of the 22 (72.3%) patients receiving an allo-PBT/CD34(+), but in only one of the 18 (5.5%) patients receiving an allo-SCT (P=0.0001). TcMC was transient (n=6), stable (n=7), and associated with poor haematopoietic engraftment (n=4). All patients with TcMC who developed graft failure had more than 30% of host T cells. Myeloid MC (MyMC) was observed in four (19%) allo-PBT/CD34(+) patients and in three (17%) allo-SCT patients (P=NS). Five out of seven (71%) patients with MyMC relapsed, all of them diagnosed with myeloid malignancies, as compared with two of the 20 (10%) patients with complete donor chimerism (P&<0.0001). In conclusion, TcMC appears in a significant number of allo-PBT/CD34(+) patients and may be associated with poor engraftment when the percentage of host T cells is >30%; likewise, MyMC appears in a small percentage of recipients of both allo-PBT/CD34(+) and allo-SCT patients, and is associated with leukaemia relapse in myeloid malignancies.

Allogeneic transplantation of CD34(+) selected cells from peripheral blood from human leukocyte antigen-identical siblings: detrimental effect of a high number of donor CD34(+) cells?

Clinical results after T-cell-depleted allografts might be improved by modifying the graft content of progenitor and accessory cells. Although the association of the number of donor T cells with the clinical outcome has been studied extensively, the optimum number of progenitor cells that should be administered to patients is unknown. The characteristics of 84 consecutive human leukocyte antigen (HLA)-identical sibling transplants of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood progenitor cells depleted of T cells by CD34(+) positive selection (allo-PBT/CD34(+)) were analyzed for their effect on clinical outcome. After a median follow-up of 24 months (range, 1-70 months), 50 patients remain alive (59.5%) and 34 have died (21 [25%] as a result of the transplant and 13 [15.5%] due to disease relapse). The median number of CD34(+) cells administered to the patients was 3.9 x 10(6)/kg (range, 1.2-14.3 x 10(6)/kg). A number of CD34(+) cells in the inoculum of 1 x 10(6)/kg to 3 x 10(6)/kg was associated with increased survival: 21 of 28 (75%) patients are alive, as compared with 29 of 56 (52%) patients receiving more than 3 x 10(6)/kg (actuarial probability 75% vs. 42%, respectively; P =.01). In the multivariate analysis, the independent prognostic variables for survival were CD34(+) cell dose 1 x 10(6)/kg to 3 x 10(6)/kg (RR = 4.8; P =.0008), sex-pairing match (RR = 3.2; P =.002), and early stage of disease (RR = 2.8; P =.007). From these results it appears that, in allo-PBT/CD34(+) from HLA-identical siblings, a number of CD34(+) cells in the inoculum between 1 x 10(6)/kg to 3 x 10(6)/kg is an important factor for better survival, and that higher CD34(+) cell doses might be associated with a poorer outcome.

Bacteremia caused by Capnocytophaga species in patients with neutropenia and cancer: results of a multicenter study.

We investigated 28 cases of bacteremia caused by Capnocytophaga species that occurred during an 8-year period, most of which were in patients with hematologic malignancy and neutropenia. Infections were uncomplicated, without serious organ involvement and without any apparent source except ulcerations of the oropharyngeal mucosa, and only 1 isolate showed resistance to beta-lactam antibiotics; 9 of 16 isolates were resistant to ciprofloxacin.

MRI and CSF oligoclonal bands after autologous hematopoietic stem cell transplantation in MS.

OBJECTIVE: To analyze the MRI and CSF oligoclonal bands (OB) changes in patients with MS who underwent an autologous hematopoietic stem cell transplantation (AHSCT). BACKGROUND: AHSCT is evaluated as an alternative therapy in severe MS. In previous series of AHSCT for MS, data on MRI or OB outcome were limited or not provided. METHODS: Five patients with a median Kurtzke's EDSS score of 6.5, more than two attacks, and confirmed worsening of the EDSS in the previous year received an AHSCT. Hematopoietic stem cells were mobilized with cyclophosphamide (3 g/m2) and granulocyte colony-stimulating factor (5 microg/kg/d). The graft was T cell depleted by positive CD 34+ selection. Conditioning regimen included BCNU (300 mg/m(2)), cyclophosphamide (150 mg/kg in 3 days), and antithymocyte globulin (60 mg/kg in 4 days). MRI scans were scheduled at baseline and 1, 3, 6, and 12 months and OB analysis at baseline and 3 and 12 months post-AHSCT. RESULTS: Four patients had a stable or improved EDSS after a median follow-up of 18 months (range, 12 to 24 months). The fifth patient's condition deteriorated during AHSCT. She partially improved and remained stable after month 3 after AHSCT. The baseline CSF OB persisted 1 year after AHSCT. MRI studies after AHSCT showed no enhanced T1 lesions and no new or enlarging T2 lesions. The median percentage change of T2 lesion load was -11.8% (range, -26.6 to -4.0%). All patients had a decrease of corpus callosum area at 1 year (median, 12.4%; range, 7.8% to 20.5%) that did not progress in the two patients evaluated at 2 years after AHSCT. CONCLUSIONS: Although the persistence of CSF OB suggests the lymphocytes were not eliminated from the CNS, the follow-up MRI studies showed no enhanced T1 brain lesions and a reduction in the T2 lesion load that correlated with the clinical stabilization of MS after AHSCT.

Allogenic stem cell transplantation as salvage therapy for patients relapsing after autologous transplantation: experience from a single institution.

The prognosis of patients relapsing after an autologous transplant (autoSCT) is very poor. Allogenic stem cell transplantation (alloSCT) offers the possibility of curing some of these patients, at the cost, however, of a high transplant related mortality (TRM). The aim of this study was to analyze the outcome of 14 consecutive patients with hematologic malignancies, from a single institution, who underwent alloSCT for progressive disease after autoSCT. Patients had relapsed at a median of 11.5 months (range 2-72) after autoSCT and they underwent alloSCT at a median of 25.5 months (range 7-73) from the first transplant. Ten patients received HLA-identical related peripheral blood progenitor cells, three patients underwent matched-unrelated donor marrow transplants, and one patient received a mismatched related transplant. Conditioning regimens consisted of total body irradiation plus cyclophosphamide (n=5) or melphalan (n=1), or high-dose combination chemotherapy (n=8). Cyclosporin A and methotrexate were administered as graft-versus-host disease (GVHD) prophylaxis. Eight patients (57%) developed grade II-IV acute GVHD. All evaluable patients (n=6) presented extensive chronic GVHD. Overall survival at 1 year was 16% (median 3.5 months, 95% CI 0.7-10.3). Ten patients (71%) died from transplant related complications at a median of 3.5 months (range 0.7-11). Only one patient died of recurrent disease. Three patients remain alive and in complete remission at the time of this report (4, 20 and 20 months, respectively). In conclusion, alloSCT offers the possibility of a sustained control of the disease in some patients who relapse after an autoSCT. However, the procedure is associated with a high transplant-related mortality. Better results might be obtained by carefully selecting patients and by reducing the intensity of the preparative regimen.

Reduced-intensity conditioning reduces the risk of severe infections after allogeneic peripheral blood stem cell transplantation.

We compared the occurrence of severe infections following 71 reduced-intensity conditioning (RIC) allogeneic peripheral blood stem cell transplants (PBSCT) and 123 standard myeloablative PBSCT (MINI and STAND groups, respectively) from HLA-identical siblings. The probability of 1-year infection-related mortality (IRM) was 19% in the STAND group and 10% in the MINI group (log-rank, P = 0.3). On multivariate analysis the only significant variable associated with a higher risk of IRM was the development of moderate-to-severe GVHD (P = 0.005). The probability of developing CMV infection was 39% in the STAND group and 21% in the MINI group (P = 0.03) (43% and 21%, respectively, in seropositive donor/recipient pairs, P = 0.01), and the probability of developing CMV disease was 9.5% and 1%, respectively (P = 0.05) (11% and 1%, respectively, in seropositive donor/recipient pairs, P = 0.03). Multivariate analysis of CMV infection identified four variables associated with a higher risk: CMV positive serostatus (P = 0.05), STAND transplant group (P = 0.02), the development of moderate-to-severe GVHD (P < 0.001) and a dose of CD34(+) cells infused below 6 x 10(6)/kg (P = 0.01). Invasive fungal infections and pneumonias of unknown origin did not differ between groups, and neither did other severe non-CMV viral infections and bacterial infections. Our results suggest that RIC allogeneic PBSCT may decrease the risk of dying from an opportunistic infection and reduces the occurrence of CMV infection and disease. Overall, the development of GVHD (acute or chronic) is an important risk factor for these complications. Other infections continue to pose a significant threat to recipients of RIC allografts, stressing that prophylactic and supportive measures are an important aspect in their care.

Allogeneic transplantation of CD34+-selected cells from peripheral blood in patients with myeloid malignancies in early phase: a case control comparison with unmodified peripheral blood transplantation.

An allogeneic transplantation of CD34(+)-selected cells from peripheral blood (allo-PBT/CD34(+)) from HLA-identical sibling donors was performed in 50 adult patients with acute myeloid leukemia in first complete remission (AML CR1) (n = 29), myelodysplastic syndrome (MDS) (n = 4), or chronic myeloid leukemia in first chronic phase (CML CP1) (n = 17). Clinical results were compared to a concurrent group of 50 patients transplanted with unmodified peripheral blood progenitor cells (allo-PBT), matched for age, diagnosis, and disease stage. The median follow-up period was 29 months (range 1-69). The actuarial probability of developing acute GVHD clinical grade II to IV was 16% (95%CI: 6-26) for the allo-PBT/CD34(+) group and 41% (95%CI: 29-57) for the allo-PBT group (P = 0.002). The actuarial probability of developing extensive chronic GVHD was 22% (95%CI: 8-36) for the allo-PBT/CD34(+) group and 47% (95%CI: 31-63) for the allo-PBT group (P = 0.02). Recipients of allo-PBT/CD34(+) had less toxicity associated with the transplant and better Karnofsky index at the last follow-up. For AML/MDS patients, the actuarial probability of disease-free survival (DFS) for recipients of allo-PBT/CD34(+) and allo-PBT was 65% (95%CI: 45-85) vs43% (95%CI: 28-58) (P = 0.05), respectively. These data provide a rationale for a randomised trial of allo-PBT/CD34(+) vs allo-PBT in AML/MDS patients in early stage of the disease.

Dramatic improvement of POEMS syndrome following autologous haematopoietic cell transplantation.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, serum monoclonal protein and skin changes) is a rare plasma cell disorder of unknown pathogenesis and is diagnosed by the demonstration of a plasma cell proliferation at the biopsy of an osteoesclerotic lesion. When the lesions are in a limited area, radiation therapy is usually highly effective. Patients with disseminated disease require systemic chemotherapy, which is not effective in most cases. A patient with severe widespread POEMS syndrome resistant to melphalan who experienced a dramatic improvement after high-dose melphalan followed by autologous haematopoietic cell transplantation (AHCT) is reported. We believe that this is the first reported case of POEMS syndrome treated with AHCT, a procedure that could be considered in similarly affected patients.

Pulmonary infiltrates in non-HIV immunocompromised patients: a diagnostic approach using non-invasive and bronchoscopic procedures.

BACKGROUND: The development of pulmonary infiltrates is a frequent life threatening complication in immunocompromised patients, requiring early diagnosis and specific treatment. In the present study non-invasive and bronchoscopic diagnostic techniques were applied in patients with different non-HIV immunocompromised conditions to determine the aetiology of the pulmonary infiltrates and to evaluate the impact of these methods on therapeutic decisions and outcome in this population. METHODS: The non-invasive diagnostic methods included serological tests, blood antigen detection, and blood, nasopharyngeal wash (NPW), sputum and tracheobronchial aspirate (TBAS) cultures. Bronchoscopic techniques included fibrobronchial aspirate (FBAS), protected specimen brush (PSB), and bronchoalveolar lavage (BAL). Two hundred consecutive episodes of pulmonary infiltrates were prospectively evaluated during a 30 month period in 52 solid organ transplant recipients, 53 haematopoietic stem cell transplant (HSCT) recipients, 68 patients with haematological malignancies, and 27 patients requiring chronic treatment with corticosteroids and/or immunosuppressive drugs. RESULTS: An aetiological diagnosis was obtained in 162 (81%) of the 200 patients. The aetiology of the pulmonary infiltrates was infectious in 125 (77%) and non-infectious in 37 (23%); 38 (19%) remained undiagnosed. The main infectious aetiologies were bacterial (48/125, 24%), fungal (33/125, 17%), and viral (20/125, 10%), and the most frequent pathogens were Aspergillus fumigatus (n=29), Staphylococcus aureus (n=17), and Pseudomonas aeruginosa (n=12). Among the non-infectious aetiologies, pulmonary oedema (16/37, 43%) and diffuse alveolar haemorrhage (10/37, 27%) were the most common causes. Non-invasive techniques led to the diagnosis of pulmonary infiltrates in 41% of the cases in which they were used; specifically, the diagnostic yield of blood cultures was 30/191 (16%); sputum cultures 27/88 (31%); NPW 9/50 (18%); and TBAS 35/55 (65%). Bronchoscopic techniques led to the diagnosis of pulmonary infiltrates in 59% of the cases in which they were used: FBAS 16/28 (57%), BAL 68/135 (51%), and PSB 30/125 (24%). The results obtained with the different techniques led to a change in antibiotic treatment in 93 cases (46%). Although changes in treatment did not have an impact on the overall mortality, patients with pulmonary infiltrates of an infectious aetiology in whom the change was made during the first 7 days had a better outcome (29% mortality) than those in whom treatment was changed later (71% mortality; p=0.001). CONCLUSIONS: Non-invasive and bronchoscopic procedures are useful techniques for the diagnosis of pulmonary infiltrates in immunocompromised patients. Bronchial aspirates (FBAS and TBAS) and BAL have the highest diagnostic yield and impact on therapeutic decisions.

Severe infections after allogeneic peripheral blood stem cell transplantation: a matched-pair comparison of unmanipulated and CD34+ cell-selected transplantation.

BACKGROUND AND OBJECTIVES: T-cell depletion of the graft delays immune recovery following allogeneic peripheral blood stem cell transplantation (PBSCT), but it is not clear whether it actually increases the risk of severe infections after the transplant. DESIGN AND METHODS: We have compared the occurrence of severe infections following 162 CD34+ cell-selected allogeneic PBSCT and 162 unmanipulated PBSCT (CD34+ and UM groups, respectively) from HLA-identical siblings. RESULTS: The probability of infection-related mortality (IRM) was 22% in the UM group and 31% in the CD34+ group (log-rank, p=0.2). In multivariate analyses only the use of fluconazole prophylaxis showed a protective effect on IRM in the whole set of patients, while in both transplant groups the most significant factor was the development of moderate-to-severe graft-versus-host disease (GVHD). The probability of developing cytomegalovirus (CMV) infection was 42% in the UM group and 59% in the CD34+ group (p=0.002), with no differences in CMV disease (10% and 9%, respectively). Multivariate analysis of CMV infection identified three variables associated with a higher risk in the whole set of patients: CMV positive serostatus, CD34+ transplant group and recipient age above 40 years. The development of moderate-to-severe GVHD was a significant factor only in the UM group. Disseminated varicella-zoster virus infection was more common in the CD34+ group (19% and 12%, p=0.05), as were early (< 30 days post-transplant) severe bacterial infections (28% vs 14%, p=0.002). Invasive fungal infections and pneumonias of unknown origin did not differ between groups. INTERPRETATION AND CONCLUSIONS: Our results do not show a significant increase in the risk of dying from an opportunistic infection with CD34+-PBSCT, but the risk of CMV infection is increased, with no differences in CMV disease or mortality attributable to CMV. There is an additive effect on IRM of developing moderate-to-severe GVHD (acute or chronic) following CD34+-PBSCT, and in this subset of patients maximum efforts for the prevention and early treatment of opportunistic infections should be pursued.

Toxoplasmosis after hematopoietic stem cell transplantation.

Forty-one cases of toxoplasmosis were diagnosed in 15 European transplantation centers in patients who had undergone allogeneic hematopoietic stem cell transplantation (HSCT) from 1994 through 1998. Most patients (39 [94%]) were seropositive for Toxoplasma gondii before they underwent transplantation, and 30 (73%) had developed moderate to severe acute graft-versus-host disease before they developed toxoplasmosis. Thirty-five (85%) patients had Toxoplasma disease with evidence of organ involvement, whereas 6 (15%) patients had Toxoplasma infection, as defined by fever and a positive polymerase chain reaction (PCR) finding for T. gondii in blood. Nine patients were diagnosed at autopsy. Thirty patients (73%) had not received antimicrobial prophylaxis with anti-Toxoplasma activity after undergoing transplantation. The median day of onset of disease after HSCT was 64. Twenty-two (63%) patients died from toxoplasmosis, and 23 (66%) received adequate anti-Toxoplasma therapy for > or =3 days. Among these 23 patients, 11 (48%) showed a complete response and 3 (13%) showed improvement. In univariate and multivariate analyses, having received adequate therapy and experiencing late infection (>63 days after HSCT) were associated with a lower risk of dying from toxoplasmosis. Toxoplasmosis after HSCT is a severe infection with a high mortality rate even when diagnosed soon after HSCT, and PCR may help establish the diagnosis earlier.

Tuberculosis after hematopoietic stem cell transplantation: incidence, clinical characteristics and outcome. Spanish Group on Infectious Complications in Hematopoietic Transplantation.

A national survey of tuberculosis after hematopoietic stem cell transplant (SCT) was undertaken to study incidence, clinical presentation and outcome. Twenty confirmed cases were found among 8,013 patients (eight in 5,147 autologous and 12 in 2,866 allogeneic SCT). The estimated incidence in cases/10(5) patients/year (95% CI) was 101 (56.5-145) for the whole group, 71.1 (21.8-120) in autologous and 135.6 (58.9-212) in allogeneic transplants. Compared with the general population, tuberculosis was more frequent after allogeneic (RR 2.95) but not after autologous SCT. Tuberculosis after SCT is a late infection (median 324 days post transplant), predominately affects the lungs (80% of the cases), appears to respond well to treatment but has a high mortality (25%) in allogeneic recipients. It can also complicate the post-transplant management as antituberculosis drugs frequently decrease the serum levels of cyclosporine causing an aggravation of GVHD. Graft-versus-host disease, corticosteroid treatment and total body irradiation appear to be associated with tuberculosis in allogeneic recipients. No obvious factors were associated with tuberculosis in autologous transplants. Finally, we found that the published literature on tuberculosis after solid and SCT has overestimated its incidence due to the direct translation of tuberculosis frequency into incidence.

Patients with mantle-cell lymphoma relapsing after autologous stem cell transplantation may be rescued by allogeneic transplantation.

Two patients with disseminated mantle-cell lymphoma relapsed 24 and 13 months, respectively, after high-dose chemotherapy and autologous stem cell transplantation (autoSCT). Both patients had an HLA-identical sibling and received an allogeneic stem cell transplant (alloSCT) 32 and 18 months after autologous transplant, after conditioning with fractionated 12 Gy total body irradiation plus cyclophosphamide 120 mg/kg. They are both alive and in complete remission 24 months after transplant. Both patients have developed chronic graft-versus-host disease and their Karnofsky performance status is 90%. AlloSCT may offer a useful approach in a subgroup of patients with mantle-cell lymphoma who have relapsed after autologous transplantation.

Complete remission of idiopathic myelofibrosis following donor lymphocyte infusion after failure of allogeneic transplantation: demonstration of a graft-versus-myelofibrosis effect.

A patient with idiopathic myelofibrosis (IM) in the osteosclerotic phase received an allogeneic stem cell transplant. Hemopoietic engraftment was rapid, and full donor chimerism was observed on day +70. However, a few months later, replacement of donor hemopoiesis by the patient's 20q- cell clone was observed, followed by reappearance of the blood IM features, marrow fibrosis and osteosclerosis. At 8 months from transplant donor lymphocytes were infused, which induced chronic GVHD. This resulted in normalization of the blood, with disappearance of the fibrosis and osteosclerosis, effects which persisted 20 months later. This case provides evidence for a graft-versus-disease effect in IM.

High-dose therapy autotransplantation/intensification vs continued standard chemotherapy in multiple myeloma in first remission. Results of a non-randomized study from a single institution.

The purpose of this study was to analyze the outcome of patients with multiple myeloma (MM) responding to initial chemotherapy who received intensification with high-dose therapy/autotransplantation (HDT) as compared to that of those who were continued on standard chemotherapy. From 1 January 1990 to 30 June 1998, 64 patients with MM who were younger than 65 years achieved a response to initial chemotherapy. Due to referral reasons, patients preference or inclusion in trials, 31 patients received HDT as early intensification while 33 were continued on standard chemotherapy. The presenting features were similar in both groups, except for the median age, which was lower in the HDT group (53 vs 58 years, P = 0.007). Complete response negative immunofixation - (CR) was achieved in 12 of 31 (39%) patients intensified with HDT and in two of 33 (6%) patients who were continued on conventional chemotherapy (P = 0.002). Event-free survival (EFS) was significantly longer in the HDT group (median, 43 vs 21 months; P = 0.007). Overall survival (OS) was not significantly different between groups (median, 62 vs 38 months; P = 0.21). However, patients in the HDT group who achieved CR had an EFS (median, 51 vs 31 months; P = 0.03) as well as an OS (median, not reached vs 50 months; P = 0.0006) significantly longer than those achieving a lower degree of response. In conclusion, this non-randomized study shows that early HDT increases CR rate and prolongs EFS. In addition, these results highlight CR as a crucial step for achieving long-lasting disease control and prolonged survival in patients with MM.

Itraconazole oral solution for primary prophylaxis of fungal infections in patients with hematological malignancy and profound neutropenia: a randomized, double-blind, double-placebo, multicenter trial comparing itraconazole and amphotericin B.

Systemic and superficial fungal infections are a major problem among immunocompromised patients with hematological malignancy. A double-blind, double-placebo, randomized, multicenter trial was performed to compare the efficacy and safety of itraconazole oral solution (2.5 mg/kg of body weight twice a day) with amphotericin B capsules (500 mg orally four times a day) for prophylaxis of systemic and superficial fungal infection. Prophylactic treatment was initiated on the first day of chemotherapy and was continued until the end of the neutropenic period (>0.5 x 10(9) neutrophils/liter) or up to a maximum of 3 days following the end of neutropenia, unless a systemic fungal infection was documented or suspected. The maximum treatment duration was 56 days. In the intent-to-treat population, invasive aspergillosis was noted in 5 (1.8%) of the 281 patients assigned to itraconazole oral solution and in 9 (3.3%) of the 276 patients assigned to oral amphotericin B; of these, 1 and 4 patients died, respectively. Proven systemic fungal infection (including invasive aspergillosis) occurred in 8 patients (2.8%) who received itraconazole, compared with 13 (4.7%) who received oral amphotericin B. Itraconazole significantly reduced the incidence of superficial fungal infections as compared to oral amphotericin B (2 [1%] versus 13 [5%]; P = 0.004). Although the incidences of suspected fungal infection (including fever of unknown origin) were not different between the groups, fewer patients were administered intravenous systemic antifungals (mainly intravenous amphotericin B) in the group receiving itraconazole than in the group receiving oral amphotericin B (114 [41%] versus 132 [48%]; P = 0.066). Adequate plasma itraconazole levels were achieved in about 80% of the patients from 1 week after the start of treatment. In both groups, the trial medication was safe and well tolerated. Prophylactic administration of itraconazole oral solution significantly reduces superficial fungal infection in patients with hematological malignancies and neutropenia. The incidence of proven systemic fungal infections, the number of deaths due to deep fungal infections, and the use of systemic antifungals tended to be lower in the itraconazole-treated group than in the amphotericin B-treated group, without statistical significance. Itraconazole oral solution is a broad-spectrum systemic antifungal agent with prophylactic activity in neutropenic patients, especially for those at high risk of prolonged neutropenia.
