    ABSTRACT: Vanishing bile duct syndrome (VBDS) in association with Hodgkin lymphoma (HL) is well described but not well understood. We report an unusual case of a 75-year-old patient presenting with biopsy-proven VBDS and immunodeficiency, without identifiable cause, which showed a waxing and waning course, culminating in the development of HL 18 months later. To our knowledge, this is the first adult case in which VBDS preceded the diagnosis of HL by such a long period.

    ABSTRACT: Invasive fungal disease (IFD) causes significant morbidity and mortality in patients undergoing allogeneic haemopoietic stem cell transplantation or chemotherapy for haematological malignancy. Much of these adverse outcomes are due to the limited ability of traditional diagnostic tests (i.e. culture and histology) to make an early and accurate diagnosis. As persistent or recurrent fevers of unknown origin (PFUO) in neutropenic patients despite broad-spectrum antibiotics have been associated with the development of IFD, most centres have traditionally administered empiric antifungal therapy (EAFT) to patients with PFUO. However, use of an EAFT strategy has not been shown to have an overall survival benefit and is associated with excessive antifungal therapy use. As a result, the focus has shifted to developing more sensitive and specific diagnostic tests for early and more targeted antifungal treatment. These tests, including the galactomannan enzyme-linked immunosorbent assay and Aspergillus polymerase chain reaction (PCR), have enabled the development of diagnostic-driven antifungal treatment (DDAT) strategies, which have been shown to be safe and feasible, reducing antifungal usage. In addition, the development of effective antifungal prophylactic strategies has changed the landscape in terms of the incidence and types of IFD that clinicians have encountered. In this review, we examine the current role of EAFT and provide up-to-date data on the newer diagnostic tests and algorithms available for use in EAFT and DDAT strategies, within the context of patient risk and type of antifungal prophylaxis used. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

    ABSTRACT: There is a strong argument for the use of antifungal prophylaxis in high-risk patients given the significant mortality associated with invasive fungal disease, the late identification of these infections, and the availability of safe and well-tolerated prophylactic medications. Clinical decisions about which patients should receive prophylaxis and choice of antifungal agent should be guided by risk stratification, knowledge of local fungal epidemiology, the efficacy and tolerability profile of available agents, and estimates such as number needed to treat and number needed to harm. There have been substantial changes in practice since the 2008 guidelines were published. These include the availability of new medications and/or formulations, and a focus on refining and simplifying patient risk stratification. Used in context, these guidelines aim to assist clinicians in providing optimal preventive care to this vulnerable patient demographic. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

    ABSTRACT: The myelodysplastic syndromes (MDS) are a group of disorders characterized by ineffective haematopoiesis, bone marrow dysplasia and cytopenias. Failure of red cell production often results in transfusion dependency with subsequent iron loading requiring iron chelation in lower risk patients. Consistent with previous reports, we have observed haematopoietic improvement in a cohort of patients treated with the oral iron chelator deferasirox (DFX). It has been postulated that MDS patients have a pro-inflammatory bone marrow environment with increased numbers of activated T cells producing elevated levels of tumour necrosis factor (TNF), which is detrimental to normal haematopoiesis. We demonstrate that DFX inhibits nuclear factor (NF)-κB dependent transcription without affecting its proximal activation, resulting in reduced TNF production from T cells stimulated in vitro. These results suggest that the haematopoietic improvement observed in DFX-treated patients may reflect an anti-inflammatory effect, mediated through inhibition of the transcription factor NF-κB and support the therapeutic targeting of this pathway, which is aberrantly activated in a large proportion of haematological malignancies.

    ABSTRACT: The effectiveness of ethanol locks for prevention of central venous catheter (CVC)-associated bloodstream infection (CLABSI) in adult haematology patients has not been thoroughly evaluated. This study aimed to compare prospectively heparinized saline with 70% ethanol locks using 2 h dwell time in patients with tunnelled CVCs. In saline (N = 43) and ethanol (N = 42) groups, CLABSI rates were 6.0 [95% confidence interval (CI): 3.4–9.8] and 4.1 (95% CI: 1.9–7.7) per 1000 CVC days, respectively (P = 0.42). In the ethanol group, two exit-site infections and one tunnel/pocket infection were observed. Reduction in device-associated infection was not achieved with prophylactic 70% ethanol locks in patients with haematological malignancy and tunnelled CVCs.

    ABSTRACT: The efficacy of a fixed-dose rituximab schedule was prospectively explored in primary/acute refractory, relapsed or chronic (platelet count >10 × 109/l and ≤50 × 109/l) idiopathic thrombocytopenic purpura (ITP). Patients received two doses of rituximab (1000 mg) on days 1 and 15 and were followed-up on weeks 1–8, 12, 26, 39 and 52. A total of 122 patients were included in the safety population; efficacy was analysed in 108 patients. Overall response rate (ORR) at week 8, defined as the proportion of patients achieving complete response (CR; platelet count >150 × 109/l) or partial response (PR; platelet count >50 × 109/l) was 44%. Therapeutic response, defined as achieving a response at week 8, with at least a minor response (MR; platelet count >30 × 109/l), sustained up to weeks 26 and 52 and accompanied by a reduction in ITP medications, was achieved in 44% (week 26) and 35% (week 52) of patients, respectively. Treatment was well tolerated with no safety concerns. While this study failed to meet its primary endpoint of an ORR of 50%, the efficacy of two fixed doses of rituximab appear to provide similar efficacy to the standard 375 mg/m2 four-dose schedule in relapsed/chronic ITP.

    ABSTRACT: In CML patients, a BCR-ABL1 value >10% at 3 months of therapy is statistically associated with poorer outcome, yet many of these patients still achieve satisfactory outcomes. We investigated 528 first-line imatinib-treated patients to determine whether patients with the poorest outcome can be better discriminated at 3 months. All outcomes were significantly superior for the 410 patients with BCR-ABL1 ≤10% at 3 months, P<.001. However, the poorest outcomes among the 95 evaluable patients with BCR-ABL1 >10% at 3 months were identified by the rate of BCR-ABL1 decline from baseline; assessed by estimating the number of days over which BCR-ABL1 halved. Patients with BCR-ABL1 halving time less than 76 days (n=74) had significantly superior outcomes compared to patients whose BCR-ABL1 values did not halve by 76 days (n=21); 4 year overall survival 95% versus 58%, P=.0002; progression-free survival 92% versus 63%, P=.008; failure-free survival 59% versus 6%, P<.0001; and MMR 54% versus 5%, P=.008. By multivariate analysis, the halving time was an independent predictor of outcome in this poor risk group. Our study has highlighted that the rate of BCR-ABL1 decline may be a critical prognostic discriminator of the patients with very poor outcome among those >10% at 3 months.

    ABSTRACT: Increasing dose intensity (DI) of chemotherapy for patients with aggressive non-Hodgkin lymphoma (NHL) may improve outcomes at the cost of increased toxicity. This issue was addressed in a randomised trial aiming to double the DI of myelosuppressive drugs. Between 1994 and 1999, 250 patients with previously untreated aggressive NHL were randomised to treatment with 6 cycles of three weekly standard (s) or intensive (i) chemotherapy: s-CEOP – cyclophosphamide 750 mg/m2, epirubicin 75 mg/m2, vincristine 1.4 mg/m2 all on day 1 and prednisolone 100 mg days 1-5; i-CEOP – cyclophosphamide 1500 mg/m2, epirubicin 150 mg/m2, vincristine 1.4 mg/m2 all on day 1 and prednisolone 100 mg days 1-5. Primary endpoint was 5-year overall survival (OS). Relative to s-CEOP patients, i-CEOP patients achieved a 78% increase in the DI of cyclophosphamide and epirubicin. Despite this, there was no significant difference in any outcome: 5-year OS (56.7% i-CEOP; 55.1% s-CEOP; P=0.80); 5-year PFS (41% i-CEOP; 43% s-CEOP; P=0.73), 5-year TTP (44% i-CEOP; 47% s-CEOP; P=0.72) or CR + unconfirmed CR (CRu) rates (53% i-CEOP; 59% s-CEOP; P=0.64). Long-term follow up at 10 years also showed no significant differences in OS, PFS, or TTP. The i-CEOP arm had higher rates of febrile neutropenia (70% vs 26%), hospitalisations, blood product utilisation, haematological and gastrointestinal toxicities, and lower QOL scores during treatment, although without significant differences 6 months later. In the treatment of aggressive NHL in the pre-rituximab era, increasing DI did not result in improved outcomes while at the same time lead to increased toxicity.

    ABSTRACT: To identify favored choice of transplantation in patients with acute promyelocytic leukemia in second complete remission. We studied 294 acute promyelocytic leukemia (APL) patients receiving allogeneic (n=232) or autologous (62) hematopoietic cell transplantation (HCT) in second complete remission (CR2) reported to the Center for International Blood and Marrow Transplantation Research (CIBMTR) from 1995 to 2006 including pre-HCT PML/RAR∝ status in 155 (49% of allogeneic and 66% of autologous). Patient characteristics and transplant characteristics including treatment related mortality, overall survival, and disease free survival were collected and analyzed for both univariate and multivariate outcomes. With median follow-up of 115 (allogeneic) and 72 months (autologous), 5-year disease-free survival (DFS) favored autologous 63% (49-75%) compared to allogeneic 50% (44-57%) (p=0.10) and overall survival (OS) 75% (63-85%) vs. 54% (48-61%) (p=.002) Multivariate analysis showed significantly worse DFS after allogeneic HCT (HR=1.88, 95% CI=1.16-3.06, p=0.011) and age >40 years (HR=2.30, 95% CI 1.44-3.67, p=0.0005). OS was significantly worse after allogeneic HCT (HR=2.66, 95%CI 1.52-4.65, p=0.0006; age >40 (HR=3.29, 95% CI 1.95-5.54, p<0.001) and CR1<12 months (HR=1.56 95% CI 1.07-2.26, p=0.021). Positive pre-HCT PML-RAR∝ status in 17/114 allogeneic and 6/41 autologous transplants did not influence relapse, treatment failure or survival in either group. The survival advantage for autografting was attributable to increased 3 years TRM: allogeneic 30%; autologous 2%, and GVHD. We conclude that autologous HCT yields superior overall survival for APL in CR2. Long term DFS in autologous recipients, even with MRD+ grafts remains an important subject for further study.

    ABSTRACT: Therapeutic options are limited for elderly patients with acute myeloid leukemia (AML). A phase Ib/II study was undertaken to evaluate the maximum-tolerated dose (MTD) and preliminary efficacy of the pan-histone deacetylase inhibitor panobinostat (LBH589) in combination with azacitidine in patients with AML or high-risk myelodysplastic syndrome (MDS) naïve to intensive chemotherapy. Thirty-nine patients (AML=29, MDS=10) received azacitidine 75 mg/m(2) subcutaneously (days 1-5) and oral panobinostat (starting on day 5, thrice weekly for seven doses) in 28-day cycles until toxicity or disease progression. Dose-limiting toxicities during the phase Ib stage were observed in 0/4 patients receiving 10 mg panobinostat, in 1/7 patients (fatigue) receiving 20 mg, in 1/6 patients (fatigue) receiving 30 mg and in 4/5 patients (fatigue, syncope, hyponatremia and somnolence) receiving 40 mg. In phase II, an additional 17 patients received panobinostat at a MTD of 30 mg. The overall response rate (ORR=CR+CRi+PR) in patients with AML was 31% (9/29) and that in patients with MDS was 50% (5/10). After a median follow-up of 13 months, the median overall survival was 8 and 16 months in patients with AML and MDS, respectively. Increased histone H3 and H4 acetylation was a useful early biomarker of clinical response. Combining panobinostat with azacitidine was tolerable and clinically active in high-risk MDS/AML patients, warranting further exploration.

    ABSTRACT: Patients with lymphoma who have experienced a first relapse or progression and have disease deemed sensitive to salvage chemotherapy nevertheless have a high likelihood of having a second relapse. To decrease the likelihood of a second relapse after high-dose therapy (HDT) and autologous stem cell transplantation (ASCT), interferon (IFN) α-2b was given in a prospective randomized international trial. In this trial, 221 patients with varying histologic diagnoses (8 small lymphocytic, 37 follicular, 9 mantle, 90 diffuse large B-cell, 20 peripheral T-cell, 3 high-grade B-cell non-Hodgkin lymphoma, and 54 Hodgkin lymphoma) were randomly assigned to receive no further treatment (arm A: 117 patients) or IFNα-2b, 3 MU three times weekly, for 18 months (arm B: 104 patients). In arm B, 21 patients (20%) did not receive IFNα-2b because of early progression or absence of hematologic recovery, 29 patients (28%) completed the 18 months of treatment, and 54 patients (52%) interrupted treatment because of progression (23%) or toxicity (29%). Event-free survival and overall survival were not different between the two arms on an intent-to-treat analysis and also if analysis was restricted to patients who were alive and had not experienced disease progression three months after transplantation. The study was not sufficiently powered to evaluate effects in histologic subtypes. In this trial, post-autograft IFNα-2b did not improve outcomes in a heterogeneous group of patients with lymphoma.

    ABSTRACT: Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPN) but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPN specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in 9 of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events with the majority of these occurring prior-to or within three months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPN and have important clinical consequences for management.

    ABSTRACT: Central nervous system (CNS) multiple myeloma (MM) is exceedingly rare and portends a dismal prognosis. While immunomodulators have contributed to the improvement in survival in MM, they appear to have limited activity against CNS MM and, paradoxically, may contribute to the evolution of resistant MM clones capable of surviving within the CNS. We undertook a retrospective analysis to characterize the features of CNS MM and outcome in 17 patients from four institutions identified between 2000 and 2011. The median age was 58 years. Patients had received a median of three prior therapies and all had been exposed to at least one of the so-called novel anti-MM agents before the diagnosis of CNS MM. The median time to CNS disease from initial diagnosis was 36 months. Cerebrospinal fluid (CSF) light chain measurements produced discrepant results to serum light chain measurements in some patients. Treatments included systemic pharmacotherapy, intrathecal (IT) chemotherapy and/or radiotherapy (RT). The median overall survival (OS) from diagnosis of CNS MM was only 4 months. OS was significantly better in patients who received IT chemotherapy (20 months vs. 2 months, respectively; P < 0·02). We conclude that the systematic evaluation of IT therapy and diagnostic utility of CSF light chain measurements in CNS MM are warranted.

    ABSTRACT: Most patients with chronic myeloid leukemia (CML) treated with imatinib will relapse if treatment is withdrawn. We conducted a prospective clinical trial of imatinib withdrawal in 40 chronic phase CML patients who had sustained undetectable minimal residual disease (UMRD) by conventional Q-PCR on imatinib for at least 2 years. Patients stopped imatinib and were monitored frequently for molecular relapse. At 24 months the actuarial estimate of stable treatment-free remission was 47.1%. Most relapses occurred within 4 months of stopping imatinib, and no relapses beyond 27 months were seen. In the 21 patients treated with interferon before imatinib a shorter duration of interferon treatment before imatinib was significantly associated with relapse risk, as was slower achievement of UMRD after switching to imatinib. Highly sensitive patient-specific BCR-ABL DNA PCR showed persistence of the original CML clone in all patients with stable UMRD, even several years after imatinib withdrawal. No patients with molecular relapse after discontinuation have progressed or developed BCR-ABL mutations (median follow-up 42 months). All patients who relapsed remained sensitive to imatinib re-treatment. These results confirm the safety and efficacy of a trial of imatinib withdrawal in stable UMRD with frequent, sensitive molecular monitoring and early rescue of molecular relapse.

    ABSTRACT: Background: The optimal treatment strategy in patients with aggressive B cell central nervous system lymphoma suitable to receive intensive therapy is unknown. The benefit of incorporating rituximab in systemic therapy remains unclear. We performed a retrospective study examining the impact of rituximab in the context of concomitant therapies, including methotrexate, cytarabine, and radiotherapy, in patients treated with curative intent at 4 university teaching hospitals during 1996-2011.MethodsA retrospective study of CNS lymphoma cases treated at the participating institutions was performed in accordance with institutional ethical guidelines. Patients were included if they received a diagnosis of primary diffuse large B cell lymphoma of the CNS, were HIV negative, and were treated with curative intent.ResultsOne hundred twenty patients aged 21-81 years were identified. Rituximab recipients and nonrecipients were similar, except for rituximab recipients being more likely to have received a diagnosis after 2004. The median follow-up of surviving patients was 30 months. The 5-year overall survival was 46%. Univariate analysis revealed age ≤60 years, ECOG performance status ≤1, normal lactate dehydrogenase, diagnosis after 2004, and treatment with cytarabine and rituximab as predictive of favorable overall survival. Multivariate analysis identified age to be an independent predictor of overall survival, with a trend toward improved survival from the other variables that were significant in univariate analyses.ConclusionsIn this retrospective analysis, the addition of rituximab to high-dose methotrexate-based chemotherapy in patients with aggressive B cell CNS lymphoma was associated with improved overall survival. Further studies are underway to prospectively validate these findings.

    ABSTRACT: BACKGROUND: Fluconazole, posaconazole and voriconazole are used prophylactically in patients with acute myeloid leukaemia (AML). This study evaluated the clinical and economic outcomes of these agents when used in AML patients undergoing consolidation chemotherapy. METHODS: A retrospective chart review (2003-10) of AML patients receiving consolidation chemotherapy was performed. Patients were followed through their first cycle of consolidation chemotherapy. Antifungal prescribing patterns, clinical outcomes and resource consumptions were recorded. A decision analytical model was developed to depict the downstream consequences of using each antifungal agent, with success defined as completion of the designated course of initial antifungal prophylaxis without developing invasive fungal disease (IFD). Cost-effectiveness and sensitivity analyses were performed. RESULTS: A total of 106 consecutive patients were analysed. Baseline characteristics and predisposing factors for IFD were comparable between groups. Three IFDs (one proven, one probable and one suspected) occurred, all in the posaconazole group. Patients receiving posaconazole had the highest rate of intolerance requiring drug cessation (13% versus 7% in each of the fluconazole and voriconazole groups). Fluconazole conferred overall savings per patient of 26% over posaconazole and 13% over voriconazole. Monte Carlo simulation demonstrated a mean cost saving with fluconazole of AU$8430 per patient (95% CI AU$5803-AU$11 054) versus posaconazole and AU$3681 per patient (95% CI AU$990-AU$6319) versus voriconazole. One-way sensitivity analyses confirmed the robustness of the model. CONCLUSIONS: This is the first study to show that, in the setting of consolidation therapy for AML, fluconazole is the most cost-effective approach to antifungal prophylaxis compared with posaconazole or voriconazole.

    ABSTRACT: Chronic GVHD (cGVHD) is an important complication of allogeneic hematopoietic cell transplantation (HCT). As preemptive therapy might be efficacious if administered early post transplant, we set out to determine whether cGVHD can be predicted from the serum level of a biomarker on day 7 or 28. In a discovery cohort of 153 HCT recipients conditioned with BU, fludarabine and rabbit antithymocyte globulin (ATG), we determined serum levels of B-cell-activating factor, vascular endothelial growth factor, soluble TNF-α receptor 1, soluble IL2 receptor α, IL5, IL6, IL7, IL15, γ-glutamyl transpeptidase, cholinesterase, total protein, urea and ATG. Patients with low levels of IL15 (<30.6 ng/L) on day 7 had 2.7-fold higher likelihood of developing significant cGVHD (needing systemic immunosuppressive therapy) than patients with higher IL15 levels (P<0.001). This was validated in a validation cohort of 105 similarly-treated patients; those with low IL15 levels had 3.7-fold higher likelihood of developing significant cGVHD (P=0.001). Low IL15 was not associated with relapse; it trended to be associated with acute GVHD and was associated with low infection rates. In conclusion, low IL15 levels on day 7 are predictive of cGVHD, and thus could be useful in guiding preemptive therapy.Bone Marrow Transplantation advance online publication, 19 November 2012; doi:10.1038/bmt.2012.210.

    ABSTRACT: PURPOSE OF REVIEW: Therapeutic drug monitoring (TDM) may be an important adjunct to optimizing the use of posaconazole. RECENT FINDINGS: Limited clinical studies suggest that an exposure-response relationship for posaconazole exists for the treatment of established invasive fungal diseases (IFDs), with emerging but less compelling data supporting its role in prophylaxis. The high prevalence of subtherapeutic levels has not translated to high prophylactic failure rates perhaps because of preferential uptake by effector cells important in the front-line defence against Aspergillus species. Nevertheless, TDM would appear prudent in patients deemed at highest risk for IFD with correction of patient modifiable factors and attention to drug administration important in optimizing drug exposure. TDM performed within a few days after commencing posaconazole may be predictive of steady-state levels, thus minimizing the delay in obtaining results in addition to identifying a subset of patients who may remain persistently subtherapeutic and also resistant to dose-escalation. Trough levels may be supplanted by untimed levels at steady state, thereby expanding the practicalities of TDM. We propose that TDM becomes one of the several measures in an integrated approach to IFD prevention combining screening of high-risk haematology patients for invasive aspergillosis at presentation, together with prospective surveillance for IFD, explicit criteria for switching to an alternative prophylactic agent and adherence to infection control practices. SUMMARY: Growing evidence supports the value of TDM for posaconazole to identify patients who may benefit from correction of modifiable factors impacting bioavailability, dosage adjustment or switch to an alternative agent.
