Evaluation of infectious morbidity due to BTK inhibitors in indolent B-cell lymphomas: latest research findings and systematic analysis. Expert Opin Pharmacother 2024; 25:1525-1540. [PMID: 39109526 DOI: 10.1080/14656566.2024.2390121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Accepted: 08/05/2024] [Indexed: 08/28/2024]
Abstract
INTRODUCTION Randomized clinical trials (RCTs) have suggested that BTK inhibitors (BTKis) might increase infectious disease (ID) risk. Systematic analysis of this topic as derived from RCTs and clinical practice is needed. AREAS COVERED An extensive Medline, Embase, and Cochrane search of peer-reviewed sources reporting on ID morbidity in patients on BTKis was performed (1 January 2014 - 31 December 2013). Contribution of intrinsic immune defects in indolent B-cell lymphomas to this morbidity was carefully considered. EXPERT OPINION Patients with indolent B-cell lymphomas display a wide range of innate and adaptive immune defects. In addition, BTKi use is linked with an increased signal of upper respiratory tract infections (URTIs) and pneumonias, mainly grade 1-2. These agents also increase the risk of rare invasive fungal infections (IFIs), mainly due to Cryptococcus and Aspergillus spp. with a peak within several months after the start of therapy. More than half of these IFIs are fatal. Research suggests a similar ID risk across 1st, 2nd and 3rd generations of BTKis, all causing B-cell dysfunction due to BTK inhibition, along with off-target functional neutrophil/macrophage alterations. Expanding the knowledge base on ID morbidity in patients on BTKis would facilitate timely diagnosis and treatment, and improve clinical outcomes.

Abstract
Redundant tumor microenvironment (TME) immunosuppressive mechanisms and epigenetic maintenance of terminal T cell exhaustion greatly hinder functional antitumor immune responses in chronic lymphocytic leukemia (CLL). Bromodomain and extraterminal (BET) proteins regulate key pathways contributing to CLL pathogenesis and TME interactions, including T cell function and differentiation. Herein, we report that blocking BET protein function alleviates immunosuppressive networks in the CLL TME and repairs inherent CLL T cell defects. The pan-BET inhibitor OPN-51107 reduced exhaustion-associated cell signatures resulting in improved T cell proliferation and effector function in the Eμ-TCL1 splenic TME. Following BET inhibition (BET-i), TME T cells coexpressed significantly fewer inhibitory receptors (IRs) (e.g., PD-1, CD160, CD244, LAG3, VISTA). Complementary results were witnessed in primary CLL cultures, wherein OPN-51107 exerted proinflammatory effects on T cells, regardless of leukemic cell burden. BET-i additionally promotes a progenitor T cell phenotype through reduced expression of transcription factors that maintain terminal differentiation and increased expression of TCF-1, at least in part through altered chromatin accessibility. Moreover, direct T cell effects of BET-i were unmatched by common targeted therapies in CLL. This study demonstrates the immunomodulatory action of BET-i on CLL T cells and supports the inclusion of BET inhibitors in the management of CLL to alleviate terminal T cell dysfunction and potentially enhance tumoricidal T cell activity.

Abstract
Chronic lymphocytic leukemia (CLL) is characterized by immune dysfunction resulting in heightened susceptibility to infections and elevated rates of morbidity and mortality. A key strategy to mitigate infection-related complications has been immunization against common pathogens. However, the immunocompromised status of CLL patients poses challenges in eliciting an adequate humoral and cellular immune response to vaccination. Most CLL-directed therapy disproportionately impairs humoral immunity. Vaccine responsiveness also depends on the phase and type of immune response triggered by immunization. In this review, we discuss the immune dysfunction, vaccine responsiveness, and considerations for optimizing vaccine response in patients with CLL.

Abstract
Patients with chronic lymphocytic leukemia (CLL) typically suffer from frequent and severe bacterial infections. Although it is well known that neutrophils are critical innate immune cells facilitating the early defense, the underlying phenotypical and functional changes in neutrophils during CLL remain largely elusive. Using a murine adoptive transfer model of CLL, we demonstrate aggravated bacterial burden in CLL-bearing mice upon a urinary tract infection with uropathogenic Escherichia coli. Bioinformatic analyses of the neutrophil proteome revealed increased expression of proteins associated with interferon signaling and decreased protein expression associated with granule composition and neutrophil migration. Functional experiments validated these findings by showing reduced levels of myeloperoxidase and acidification of neutrophil granules after ex vivo phagocytosis of bacteria. Pathway enrichment analysis indicated decreased expression of molecules critical for neutrophil recruitment, and migration of neutrophils into the infected urinary bladder was significantly reduced. These altered migratory properties of neutrophils were also associated with reduced expression of CD62L and CXCR4 and correlated with an increased incidence of infections in patients with CLL. In conclusion, this study describes a molecular signature of neutrophils through proteomic, bioinformatic, and functional analyses that are linked to a reduced migratory ability, potentially leading to increased bacterial infections in patients with CLL.

Abstract
Chronic lymphocytic leukaemia (CLL) is a heterogeneous disease with uncertain course. Treatment should be tailored to the patient's disease as well as the prognostic subgroup. With the increased use of rituximab as well as other selective and non-selective immunomodulatory agents, the incidence of infectious complications and second malignancies has also increased. Progressive multifocal leucoencephalopathy (PML) is a complication of rituximab in HIV-negative patients. A 56-year-old male with CLL had been treated and relapsed four times in 6 years. Rituximab was added to the combination after the second relapse and repeated in the third relapse in combination with bendamustine. In the seventh year of diagnosis, relapse of CLL and an ulcerated tumorous lesion was observed in the left index finger, which progressed in 3 months and was later diagnosed as angiosarcoma. The cancer was treated with local radiotherapy and combination chemotherapy. One year after the last rituximab exposure, progressive muscle weakness developed and polyoma JC virus DNA was observed with increased titres in the cerebrospinal fluid, and the patient was diagnosed as having PML. The patient died 2 months later. Our patient had an unusual course of CLL over 8 years, with relapses, complicated with a secondary malignancy and an infectious complication.

Abstract
PURPOSE Infectious complications constitute a leading cause of morbidity and mortality in chronic lymphocytic leukemia (CLL). Patients respond poorly to vaccines, particularly pneumococcal polysaccharide and influenza vaccines. In addition, patients with genetically high-risk disease are at increased risk for early disease progression and death. Lenalidomide, an oral immunomodulatory agent with demonstrated clinical activity in CLL, can potentially restore immune system dysfunction associated with CLL while improving disease outcomes. PATIENTS AND METHODS Phase II study randomized 49 patients with genetically high-risk CLL or small lymphocytic lymphoma [SLL; defined as unmutated Ig heavy chain variable region, deletion(17p) or (11q), and/or complex abnormal karyotype], to receive lenalidomide either concurrent (arm A) or sequential to (arm B) two doses of 13-valent protein-conjugated pneumococcal vaccine (PCV13) administered 2 months apart, in patients not meeting International Workshop on Chronic Lymphocytic Leukemia treatment criteria. RESULTS Four serotypes (3, 4, 5, 6B) achieved the additional seroprotection definition of a fourfold increase in arm A, and six serotypes (3, 4, 5, 6B, 19A, 19F) in arm B. All patients achieved the defined concentration of 0.35 μg/mL for at least one serotype tested. No significant difference was observed with the addition of lenalidomide. At median time on treatment of 3.6 years, median progression-free survival (PFS) was 5.8 years [95% confidence interval (CI), 3.1-not reached]. PFS at 1, 2, and 3 years was 85% (95% CI, 72-93), 79% (95% CI, 64-88), and 72% (95% CI, 57-83), respectively. CONCLUSIONS Lenalidomide is efficacious with manageable toxicities as an early intervention strategy in patients with high-risk CLL, but did not enhance humoral response to PCV13 vaccine.

Abstract
Duvelisib (also known as IPI-145) is an oral, dual inhibitor of phosphatidylinositol 3-kinase δ and γ (PI3K-δ,γ) being developed for treatment of hematologic malignancies. PI3K-δ,γ signaling can promote B-cell proliferation and survival in clonal B-cell malignancies, such as chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). In a phase 1 study, duvelisib showed clinically meaningful activity and acceptable safety in CLL/SLL patients. We report here the results of DUO, a global phase 3 randomized study of duvelisib vs ofatumumab monotherapy for patients with relapsed or refractory (RR) CLL/SLL. Patients were randomized 1:1 to oral duvelisib 25 mg twice daily (n = 160) or ofatumumab IV (n = 159). The study met the primary study end point by significantly improving progression-free survival per independent review committee assessment compared with ofatumumab for all patients (median, 13.3 months vs 9.9 months; hazard ratio [HR] = 0.52; P < .0001), including those with high-risk chromosome 17p13.1 deletions [del(17p)] and/or TP53 mutations (HR = 0.40; P = .0002). The overall response rate was significantly higher with duvelisib (74% vs 45%; P < .0001) regardless of del(17p) status. The most common adverse events were diarrhea, neutropenia, pyrexia, nausea, anemia, and cough on the duvelisib arm, and neutropenia and infusion reactions on the ofatumumab arm. The DUO trial data support duvelisib as a potentially effective treatment option for patients with RR CLL/SLL. This trial was registered at www.clinicaltrials.gov as #NCT02004522.

Abstract
One cause of morbidity and mortality in chronic lymphocytic leukemia (CLL) is infection, which results from defects in a number of components of the immune system. In particular, dendritic cells (DCs) are functionally defective in patients with CLL. To understand the molecular mechanism for this abnormality, we focused on signal transduction pathways that regulate the function of monocyte-derived dendritic cells (Mo-DCs). Monocytes from CLL patients exhibit high IL-4Rα expression due to the enhanced activation of STAT3. However, IL-4R signaling is decoupled from activation of its downstream mediator STAT6 by enhanced levels of the negative regulator SOCS5. This impairs differentiation of functionally mature DCs leading to decreased expression of HLA-DR and costimulatory molecules, and reduced secretion of pro-inflammatory cytokines in LPS-activated DCs. Moreover, Mo-DCs from CLL patients display a decreased ability to induce pro-inflammatory T-cell responses. IL-10-treatment of monocytes from healthy donors mimics the alteration in signaling observed in CLL patients, through enhanced STAT3-dependent expression of SOCS5. The higher level of SOCS5 inhibits STAT6 activation and leads to defective DC differentiation. These findings indicate that SOCS5 mediates the impaired function of DCs in CLL patients, and has the potential to be a new therapeutic target for reversing cancer-associated immune suppression.

Abstract
We studied the risk of infections in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL). Major infections were defined as requiring hospital admission or intravenous antimicrobial treatment. Incidence rate (IR) ratios (IRR) were used to compare infection rates. Of 263 CLL patients followed for 936.9 person-years, 60% required treatment for progressive CLL (66 received ibrutinib). Infections occurred in 71.9% patients (IR 92.4/100 person-years) with 31.9% having major infections (IR 20.3/100 person-years) and infections causing 37.5% of deaths. CLL treatment was associated with significantly higher risk of major (IRR 3.31, 95% CI 2.10, 5.21) and minor (IRR 1.78, 95% CI 1.43, 2.22) infections. Compared to their previous chemoimmunotherapy patients receiving salvage ibrutinib therapy (n = 47) had a significantly increased risk of a major infection (IRR 2.35 95% CI 1.27, 4.34). The risk of infection in CLL patients remains high even with use of less immunosuppressive therapies.

[PMID: 28122892 DOI: 10.1093/jjco/hyw146] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Revised: 08/25/2016] [Accepted: 09/12/2016] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVE To evaluate the safety, efficacy and pharmacokinetics of alemtuzumab in Japanese patients, we conducted a phase I study in patients with relapsed or refractory B-cell chronic lymphocytic leukemia. METHODS Six patients received alemtuzumab by intravenous infusion every other day three times a week for 12 weeks. The dose was gradually escalated on daily basis (3, 10 and then 30 mg) until the patient tolerated. The primary objective was to evaluate the safety of alemtuzumab in Japanese patients and the secondary objectives were to evaluate the overall response rate and the pharmacokinetics. RESULTS The major treatment-emergent adverse events were anemia, neutropenia (6/6 patients each) and thrombocytopenia (5/6 patients) in hematologic adverse events, and nausea, vomiting, decreased appetite, cytomegalovirus test positive and pyrexia (4/6 patients) in non-hematologic adverse events. As serious adverse events, cytomegalovirus infection, pulmonary tuberculosis and diffuse large B-cell lymphoma were reported in 1/6 patient each. The overall response rate was 33% (95% confidence interval: 4-78) (1/6 patient each achieved complete response and partial response, respectively) and 3/6 patients had stable disease and 1/6 patient had progressive disease. The median time to response was 2.9 months. After last intravenous dosing (Week 12) of alemtuzumab 30 mg every other day three times a week, Cmax, tmax, AUC0-τ and t1/2 were higher and CL and Vss were lower than the values observed after the first dose. CONCLUSIONS The efficacy, safety and pharmacokinetics results observed with alemtuzumab in Japanese patients were generally similar to those reported in overseas clinical studies. Alemtuzumab at 30 mg by intravenous infusion every other day three times a week for 12 weeks should be safe and effective similarly in Japanese B-cell chronic lymphocytic leukemia patients. CLINICAL TRIAL REGISTRATION NO NCT00923182.

Abstract
Few reports have described the coincidence of chronic lymphocytic leukemia (CLL) and HIV. We administered bendamustine to an HIV-positive refractory CLL patient and obtained a significant objective response. Our results indicate that bendamustine can be used in HIV-infected CLL patients. We also reviewed 12 cases of CLL with HIV infection.

Abstract
PURPOSE Chemoimmunotherapy has been the standard of care for chronic lymphocytic leukemia (CLL). However, the introduction of B-cell receptor (BCR) kinase inhibitors such as ibrutinib has the potential to eliminate the role of chemotherapy in the treatment of CLL. How to best incorporate old and new therapies for CLL in this landscape is increasingly complex. METHODS This article reviews current data available to clinicians and integrates these data to provide a strategy that can be used to approach the treatment of CLL in the era of BCR signaling inhibitors. RESULTS Current strategies separate patients based on age or functional status as well as genetics [presence or absence of del(17)(p13.1)]. In the era of targeted therapy, this will likely continue based on current available data. Phase III studies support chemoimmunotherapy as the initial standard therapy for patients without del(17)(p13.1). Choice of chemotherapy (fludarabine plus cyclophosphamide, bendamustine, or chlorambucil) and anti-CD20 antibody (rituximab, ofatumumab, or obinutuzumab) varies based on regimen and patient status. For patients with del(17)(p13.1), no standard initial therapy exists, although several options supported by phase II clinical trials (methylprednisolone plus alemtuzumab or ibrutinib) seem better than chemoimmunotherapy. Treatment of relapsed CLL seems to be best supported by ibrutinib-based therapy. Completion of trials with ibrutinib and other new agents in the near future will offer opportunity for chemotherapy-free treatment across all groups of CLL. CONCLUSION Therapy for CLL has evolved significantly over the past decade with introduction of targeted therapy for CLL. This has the potential to completely transform how CLL is treated in the future.

Abstract
The treatment of chronic lymphocytic leukemia (CLL) is evolving rapidly. Insight into the genetics and biology of the disease, including the importance of intracellular signaling pathways and interactions with the microenvironment has led to the development of rational targeted therapies which are having a major impact on the survival of patients with relapsed and high-risk disease. In addition, an exciting array of cellular therapies and immunotherapy options are in various stages of development. We review the current understanding of CLL genetics and biology, current treatment strategies in specific patient groups and opportunities for future treatment combinations which will bring the goal of cure or long-term disease control with minimal toxicity within reach for the majority of patients.

Abstract
BACKGROUND Chronic lymphocytic leukemia (CLL) leads to significant immune system dysfunction. The predominant clinical presentation in 50% of patients involves recurrent, often severe, infections. Infections are also the most common (60-80%) cause of deaths in CLL patients. The scope of infections varies with the clinical stage of the disease. Treatment-naive patients typically present with respiratory tract infections caused by encapsulated bacteria Streptococcus pneumoniae and Haemophilus influenzae. Since 2012, the 13-valent pneumococcal conjugate vaccine (PCV13) has been recommended in the United States and some EU countries for pneumococcal infection prevention in patients with CLL (besides the long-standing standard, 23-valent pneumococcal polysaccharide vaccine, PPV23). The aim of this study was to compare the immune response to PCV13 in 24 previously untreated CLL patients and healthy subjects. METHODS Both groups were evaluated for: the levels of specific pneumococcal antibodies, the levels of IgG and IgG subclasses and selected peripheral blood lymphocyte subpopulations including the frequency of plasmablasts before and after immunization. RESULTS Adequate response to vaccination, defined as an at least two-fold increase in specific pneumococcal antibody titers versus pre-vaccination baseline titers, was found in 58.3% of CLL patients and 100% of healthy subjects. Both the CLL group and the control group demonstrated a statistically significant increase in the IgG2 subclass levels following vaccination (P = 0.0301). After vaccination, the frequency of plasmablasts was significantly lower (P<0.0001) in CLL patients in comparison to that in controls. Patients who responded to vaccination had lower clinical stage of CLL as well as higher total IgG, and IgG2 subclass levels. No significant vaccine-related side effects were observed. CONCLUSIONS PCV13 vaccination in CLL patients is safe and induces an effective immune response in a considerable proportion of patients. To achieve an optimal vaccination response, the administration of PCV13 is recommended as soon as possible following CLL diagnosis.

Abstract
OBJECTIVE To compare knowledge, attitudes, and risks related to pet contact in households with and without immunocompromised children. STUDY DESIGN A questionnaire was distributed to parents of children diagnosed with cancer (immunocompromised; n=80) or diabetes (immunocompetent; n=251) receiving care at the Children's Hospital of Eastern Ontario. Information was collected on knowledge of pets as sources of disease, concerns regarding pet-derived pathogens, and pet ownership practices. Data were analyzed with multivariable logistic regression. RESULTS The questionnaire was completed by 65% (214 of 331) of the individuals to whom it was given. Pet ownership was common; 45% of respondents had a household pet when their child was diagnosed, and many (households with a child with diabetes, 49%; households with a child with cancer, 20%) acquired a new pet after diagnosis. Most households that obtained a new pet had acquired a pet considered high risk for infectious disease based on species/age (diabetes, 73%; cancer, 77%). Parents of children with cancer were more likely than parents of children with diabetes to recall being asked by a physician/staff member if they owned a pet (OR, 5.9) or to recall receiving zoonotic disease information (OR, 5.3), yet these interactions were reported uncommonly (diabetes, ≤13%; cancer, ≤48%). Greater knowledge of pet-associated pathogens was associated with recalled receipt of previous education on this topic (OR, 3.9). Pet exposure outside the home was reported frequently for children in non-pet-owning households (diabetes, 48%; cancer, 25%). CONCLUSION Improved zoonotic disease education is needed for pet-owning and non-pet-owning households with immunocompromised children, with ongoing provision of information while the children are at increased risk of disease. Additional efforts from pediatric and veterinary healthcare professionals are required.

Abstract
Infectious complications remain a significant issue in the care of patients with hematologic malignancies. Inherent immune defects related to the primary disease process are present in patients with disorders such as chronic lymphocytic leukemia, multiple myeloma, hairy cell leukemia, and Hodgkin lymphoma. Therapy-related immunosuppression is also commonplace in these patients. This includes not only treatment-related neutropenia, but also defects in cell-mediated immunity, such as those that occur with purine analog therapy. In this chapter, we will review the pathogenesis of infection in these disorders, as well as the spectrum of infectious complications seen and suggested strategies for the prevention of infection.

Abstract
Herpes simplex virus has protean manifestations and is an important cause of morbidity in the immunocompromised host. We report a case of recurrent lymphadenopathy and rash in a patient with chronic lymphocytic leukemia. The elusive clinical diagnosis eventually required core biopsy of a lymph node with immunohistochemistry and confirmation by polymerase chain reaction. This case illustrates the challenging clinical and laboratory diagnosis of herpes simplex virus lymphadenitis and the need to maintain a high index of suspicion for infection when treating an immunocompromised patient with unusual and/or persistent symptoms.

Abstract
AbstractDespite the advanced age at onset, chronic lymphocytic leukemia (CLL) shortens the life expectancy of the majority of newly diagnosed patients. The management of elderly patients with CLL is more complex than that of younger patients due to the greater frequency of comorbidities and functional impairment as well as reduced organ function. Many of the recent advances in the care of CLL patients (prognostication, more intense combination therapy regimens) are of unclear relevance for elderly patients. This review addresses 5 key questions in the management of elderly patients with CLL: (1) why is classifying the “fitness” of CLL patients necessary; (2) what criteria should be used to classify patient fitness; (3) when should elderly patients be treated; (4) how should therapy be selected for elderly patients; and (5) which therapy is best (for this patient)?

Abstract
B cell-chronic lymphocytic leukemia (CLL), the commonest adult leukemia in western world, is today most often diagnosed at early-stage, following the accidental detection of lymphocytosis during a routine blood analysis. Moreover, the expectations of CLL patients have dramatically changed in the past decade and for the first time a significant overall survival improvement has been demonstrated in the disease--at least in the younger and fit patients--with the use of the FCR regimen, which combines rituximab fludarabine and cyclophosphamide. New drugs and new regimens are currently being developed for the relapsed patients and for those too old or too frail to receive aggressive treatments. Some of these promising compounds will likely be part of the future front-line treatments. Additionally, the increasing knowledge on the molecular features that predict the clinical outcome may soon result in a molecular classification of the disease. These acquisitions are producing a migration from palliative care to a curative and individually-tailored approach. In this review we tried to summarize the advances achieved in the past decade and help the specialists in internal medicine and the general practitioners to understand the completely changed scenario in which the disease should nowadays be managed.

Abstract
Purpose Chronic lymphocytic leukemia (CLL) is associated with an increased risk of developing second cancers. However, it is unknown whether CLL alters the disease course of these cancers once they occur. Patients and Methods All patients with cancers of the breast (n = 579,164), colorectum (n = 412,366), prostate (n = 631,616), lung (n = 489,053), kidney (n = 95,795), pancreas (n = 82,116), and ovary (n = 61,937) reported to the SEER program from 1990 to 2007 were identified. Overall survival (OS; death resulting from any cause) and cancer-specific survival were examined, comparing patients with and without pre-existing CLL. Cancer-specific survival was evaluated for each tumor type in a site-specific manner (eg, death resulting from breast cancer in a patient with breast cancer). Results Patients with cancers of the breast (hazard ratio [HR], 1.70; P < .001), colorectum (HR, 1.65; P < .001), kidney (HR, 1.54; P < .001), prostate (HR, 1.92; P < .001), or lung (HR, 1.19; P < .001) had inferior OS if they had a pre-existing diagnosis of CLL after adjusting for age, sex, race, and disease stage. These results for OS remained significant for patients with cancers of the breast, colorectum, and prostate after excluding or censoring CLL-related deaths. Cancer-specific survival was also inferior for patients with cancers of the breast (HR, 1.41; P = .005) and colorectum (HR, 1.46; P < .001) who had pre-existing CLL after adjusting for age, sex, race, and disease stage. Conclusion Inferior OS and cancer-specific survival was observed for several common cancers in patients with pre-existing CLL. Additional studies are needed to determine the optimal management of these malignancies in patients with CLL and whether more aggressive screening or alternative approaches to adjuvant therapy are needed.

Abstract
BACKGROUND Although recent studies have demonstrated an improvement in the prognosis of critically ill cancer patients, little is known regarding the prognosis of patients with non-aggressive underlying malignancies. The aims of this study were to assess the prognosis of critically ill patients with chronic lymphocytic leukemia (CLL) and to evaluate risk factors for hospital mortality. METHODS In retrospective mono-center cohort study, consecutive adult patients with CLL requiring ICU admission from 1997 to 2008 were included. RESULTS Sixty-two patients of 67 years (62-75) were included. Median time interval between CLL diagnosis and ICU admission was 6.7 years (2.6-10.8). Nine patients (15 %) had stage C disease at the time of ICU admission, and seven patients (11 %) had Richter syndrome. Most ICU admissions were related to bacterial or fungal pulmonary infections (n = 47; 76 %). ICU, in-hospital, and 90-day mortality were 35 % (n = 22), 42 % (n = 26), and 58 % (n = 36), respectively. Only three factors were independently associated with in-hospital mortality: oxygen saturation lower than 95 % when breathing room air (odds ratio (OR) 5.80; 95 % confidence interval (CI) 1.23-27.33), need for vasopressors (OR 27.94; 95 % CI 5.37-145.4), and past history of infection (OR 6.62; 95 % CI 1.34-32.68). The final model did not change when disease-related variables (Binet classification, Richter syndrome, long-term steroids) or treatment-related variables (fludarabine, rituximab, or alemtuzumab) were included. CONCLUSION Acute pulmonary infections remain the leading cause of ICU admission in patients with CLL. The severity at ICU admission and past history of infection were the only factors associated with hospital mortality. Neither disease characteristics nor previous cancer treatments were associated with outcome.

Abstract
Background Syncytial giant cell hepatitis (GCH) is an uncommon and an underreported disease entity. In two previously reported cases of GCH in patients with Chronic Lymphocytic Leukemia (CLL) liver failure ensued. Autoimmune and infective causes have been implicated but its etiology remains unclear. Case Presentation A 60-year-old female with CLL presented with acute hepatitis with negative viral and auto-immune serologies and without any prior toxic exposure. Liver biopsy showed typical histological features of GCH. The patient was successfully treated with corticosteroids and intravenous immunoglobulin (IVIG). Her liver enzymes returned to baseline and have remained normal as of the last follow up almost 4 years later. Conclusions Association of GCH with CLL may be under recognized. Clinical suspicion of GCH in CLL patients with serology-negative hepatitis, early liver biopsy and therapeutic intervention may influence outcome. This is the first case report of successful treatment of GCH in CLL patients. Moreover, our case also demonstrates the ability to resume effective CLL therapy post-GCH diagnosis without detriment to the liver.

Abstract
Although the risk of progression from monoclonal B-cell lymphocytosis (MBL) to chronic lymphocytic leukemia (CLL) has been well characterized, it is unknown whether other common complications associated with CLL, such as increased risk of infection, occurs in individuals with MBL. We used the Mayo CLL database to identify cohorts of individuals with newly diagnosed MBL (n=154) or newly diagnosed CLL (n=174) who resided within 50 miles of Mayo Clinic. A cohort of 689 adult patients seen for a general medical examination who resided within 50 miles of Mayo clinic and who enrolled in a case-control study of non-Hodgkin lymphoma (NHL) was used as a comparison cohort. Hospitalization with infection was more common among individuals with MBL (25/154; 16.2%), and CLL (32/174; 18.4%) than controls (18/689; 2.6%). On pooled multivariable Cox proportional hazards analysis of all 1017 patients (controls, MBL and CLL), male sex (hazards ratio (HR)=2.3; P=0.002), major co-morbid health problems (HR=1.7, P=0.04), the presence of CLL (HR=3.2, P<0.001), treatment for progressive CLL (HR=2.4, P=0.001) and the presence of MBL (HR=3.0, P=0.001) were independently associated with risk of hospitalization for infection. These results suggest the risk of serious infection in clinical MBL is substantially greater than the risk of progression requiring treatment.

Abstract
The aim of the study was to assess the frequency and predisposing factors of colonization of upper respiratory tract by Gram-negative rods (GNRs) in chronic lymphocytic leukemia (CLL) patients. Antimicrobial susceptibility of the isolated strains was determined. A significantly higher frequency of GNR colonization in CLL patients was observed (36.7%) in comparison to healthy volunteers (8.3%). GNR isolates mainly belonged to the Enterobacteriaceae family. Three isolates of GNR demonstrating presence of AmpC β-lactamases and one ESBL-producing strain were obtained from CLL patients. GNR colonization rate was higher among CLL patients with lower level of IgG in serum (P = 0.017), with higher number of neutrophils (P = 0.039) or higher number of lymphocytes in serum (P = 0.053). The longer the time elapsed since diagnosis, the higher the frequency of GNR colonization observed. Multivariate analysis showed importance of the Rai stage, number, and type of infections as independent predictors of GNR colonization in CLL patients.

Abstract
BACKGROUND The impact of physicians' disease-specific expertise on patient outcome is unknown. Although previous studies suggest a survival advantage for cancer patients cared for at high-volume centers, these observations may simply reflect referral bias or better access to advanced technologies, clinical trials, and multidisciplinary support at large centers. METHODS We evaluated time to first treatment (TTFT) and overall survival (OS) of patients with newly diagnosed chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) at a single academic center based on whether they were cared for by a hematologist/oncologist who subspecializes in CLL (CLL hematologist) or a hematologist/oncologist with expertise in other areas (non-CLL hematologist). RESULTS Among 1309 newly diagnosed patients with CLL cared for between 1999 and 2009, 773(59%) were cared for by CLL hematologists and 536 were cared for by non-CLL hematologists. Among early-stage patients (Rai 0-I), median TTFT (9.2 vs 6.1 years; P < .001) and OS (10.5 years vs 8.8 years; P < .001) were longer for patients cared for by CLL hematologists. For all patients, OS was superior for patients cared for by CLL hematologists (10.5 years vs 8.4 years; P = .001). Physician's disease-specific expertise remained an independent predictor of OS after adjusting for age, sex, stage, and lymphocyte count at diagnosis. Patients seen by a CLL hematologist were also more likely to participate in clinical trials (48% vs 16%; P < .001). CONCLUSIONS Physician disease-specific expertise appears to influence outcome in patients with CLL. To the greatest extent possible, patients should be cared for by a hematologist/oncologist expert in the care of their specific malignancy. When not possible, practice guidelines developed by disease-specific experts should be followed.

Abstract
Celiac crisis is an acute, fulminant form of celiac disease manifesting with severe diarrhea, metabolic and electrolyte abnormalities, and weight loss. It is mostly seen in children, and there are very few reports in adults. We present a 67-year-old patient with chronic lymphocytic leukemia (CLL) who presented with weight loss of 40 pounds, severe diarrhea, hypoalbuminemia and hypokalemia. The patient was immunosuppressed with hypogammaglobulinemia, which is common in CLL. Thus, the patient had negative serological studies for celiac disease. An endoscopic evaluation and HLA typing supported the diagnosis of celiac disease. Although the differential diagnosis was broad, exclusion of other etiologies for diarrhea, prompt diagnosis of celiac disease and initiation of gluten-free diet resolved the crisis. This is the first such report of a patient presenting with celiac crisis on a background of hypogammaglobulinemia.

Abstract
Before the contemporary development of rationally designed antineoplastic therapies, cladribine was identified as a lymphocyte-specific agent. Its profound impact on the natural history of hairy cell leukemia, with responses approaching 100% and a median duration of response of nearly a decade after only a single 7-day course, is well known and revolutionized the treatment of hairy cell leukemia. However, cladribine's impressive activity in other lymphoproliferative disorders has been generally underappreciated. Multiple single-arm phase 2 trials have demonstrated cladribine's potency across the full spectrum of lymphoid malignancies. In a limited number of phase 3 trials and cross-study analyses, cladribine compared favorably with fludarabine, another purine nucleoside analog that is more commonly used in the treatment of indolent lymphoid malignancies. Cladribine has been noted to have particular activity among lymphoid disorders with few effective therapies, specifically, chronic lymphocytic leukemia, lymphoplasmacytic lymphoma, marginal zone lymphoma, and mantle cell lymphoma. Recently approved novel agents may act in synergy with cladribine for these conditions and should be incorporated into future clinical studies.

Abstract
Fludarabine is an antineoplastic agent used in the treatment of hematological malignancies, particularly chronic lymphocytic leukemia (CLL) and indolent B-cell lymphoma. Because of its immunosuppressive effects, fludarabine has been added to reduced intensity conditioning regimens. The oral formulation of fludarabine has become widely available. Pharmacokinetic studies have shown that an oral dose of 40 mg/m2/d would provide systemic drug exposure similar to the standard intravenous (IV) dose of 25 mg/m2/d. The oral dose can be taken once daily without any dietary restrictions. Dose adjustments are mandatory in patients with renal impairment to avoid increased toxicity. Several noncomparative trials in previously untreated and treated patients with CLL have shown that treatment with the oral formulation demonstrates similar efficacy compared to historical control groups treated with the IV formulation. The tolerability profile of oral fludarabine seems similar to that of the IV formulation. Myelosuppression and infectious complications are the most frequently reported adverse events. Gastrointestinal toxicity is more frequent with the oral formulation, but is usually of mild or moderate severity. Although oral fludarabine makes treatment more convenient, health care workers must be aware of the compliance behavior of each patient.

Abstract
Chronic lymphocytic leukemia (CLL) involves a profound humoral immune defect and tumor-specific humoral tolerance that directly contribute to disease morbidity and mortality. CD154 gene therapy can reverse this immune defect, but attempts to do this pharmacologically have been unsuccessful. The immune-modulatory agent lenalidomide shows clinical activity in CLL, but its mechanism is poorly understood. Here, we demonstrate that lenalidomide induces expression of functional CD154 antigen on CLL cells both in vitro and in vivo. This occurs via enhanced CD154 transcription mediated by a Nuclear Factor of Activated T cells c1 (NFATc1)/Nuclear Factor-kappaB (NF-kappaB) complex and also through phosphoinositide-3 (PI3)-kinase pathway-dependent stabilization of CD154 mRNA. Importantly, CD154-positive CLL cells up-regulate BID, DR5, and p73, become sensitized to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis, and promote costimulatory activation of normal B cells to produce antibodies. In CLL patients receiving lenalidomide, similar evidence of CD154 activation is observed including BID, DR5, and p73 induction and also development of anti-ROR1 tumor-directed antibodies. Our data demonstrate that lenalidomide promotes CD154 expression on CLL cells with subsequent activation phenotype, and may therefore reverse the humoral immune defect observed in this disease. This study is registered at http://clinicaltrials.gov as NCT00466895.

Abstract
Epstein-Barr virus (EBV) is important in the development of post-transplant lymphoproliferative disease in allogeneic stem cell and solid organ transplant recipients. We have studied the clinical significance of EBV DNAaemia among nontransplant patients in a tertiary referral hospital. We retrospectively reviewed the medical records for main diagnosis, outcome, immunosuppressive/cytotoxic chemotherapy and other opportunistic infections of the patients who were found positive in quantitative real-time PCR assay for EBV (EBV-qPCR) between the years 2000 and 2007. Allogeneic stem cell and solid organ transplant recipients were excluded, and all patients in nonsurgical adult wards were included. Altogether, 62 patients had at least one plasma sample positive with an EBV-qPCR. Fifteen were immunocompetent, most had primary EBV infection, and the outcome was good. On the other hand, 36 had malignant disease, seven had HIV infection and seven had immunosuppressive conditions of an other aetiology. All but one of the malignancies were of lymphoid origin, and most of these patients had a history of multiple cytotoxic treatments. Immunosuppressed patients had higher viral loads. EBV viraemia is associated with severe immunosuppression and lymphoid malignancies.

Abstract
Long-term survival of patients with chronic lymphocytic leukemia (CLL) is over 10 years, and such patients are thus potential kidney recipients in the case of superimposed end-stage renal disease. However, the renal and patient outcome in this condition is unknown. We report the charts of four patients with CLL who were engrafted in France with a deceased-donor kidney and underwent routine triple immunosuppressive therapy. The results show that these patients developed severe infectious episodes (fatal in one case) and tumoral complications including rapid progression of CLL in two cases. Moreover, the graft may be infiltrated and damaged by monoclonal B cells: one patient lost his graft 14 months after transplantation. Various therapeutic options (modifications of the immunosuppressive regimen, anti-CD20 antibodies, irradiation of the graft) showed little (if any) efficacy. Therefore, we believe that CLL is a too hazardous condition to envisage solid organ transplantation with a routine immunosuppressive regimen, and we propose a more appropriate approach.

Abstract
BACKGROUND Chronic lymphocytic leukaemia patients harbour important impairments in both their cellular- and humoral-mediated immunity, which accounts for their notorious susceptibility to a multitude of infections and various autoimmune cytopenias. It has also been shown that the rate of second cancers is increased in chronic lymphocytic leukaemia. OBJECTIVE The aim of this study was to review the immune alterations in untreated and treated chronic lymphocytic leukaemia and define their impact for clinical practice. METHODS The author gives a comprehensive review of the most relevant preclinical and clinical studies pertaining to various immune abnormalities and infectious complications in both untreated and treated chronic lymphocytic leukaemia. Landmark clinical trials involving the contemporary chronic lymphocytic leukaemia chemo- and immunotherapies, alone or in combination, as well as the main epidemiological studies establishing the increased rate of second cancers in chronic lymphocytic leukaemia are also discussed. RESULTS/CONCLUSIONS Iatrogenic immunosuppression in chronic lymphocytic leukaemia alters the pattern of opportunistic infections, can cause autoimmune cytopenias and might further increase the rate of second malignancies in patients whose disease already places them at a greater risk. Careful consideration of existing risk factors in chronic lymphocytic leukaemia could establish the optimal screening and follow-up schedule for chronic lymphocytic leukaemia patients as its therapeutics evolves.

Abstract
INTRODUCTION Patients with chronic lymphocytic leukaemia (CLL) have progressive immunodeficiency and infection is the commonest cause of death. This review seeks to identify the extent of the abnormality, its cause, clinical significance and any possible remedy. SOURCES OF DATA TJH has studied CLL for the past 40 years and has scanned or read every paper he could find published on the topic since 1970 and most of those of historical importance published before that date. He has read around the subject, covering relevant articles on immunology, cell biology, oncology and genetics. Furthermore, he has attended most major meetings dealing with CLL in this time and has written many reviews to update the state of knowledge about the topic. He receives weekly updates of papers published on CLL from PubMed and Science Direct with the keywords 'chronic lymphocytic leukaemia'. AREAS OF AGREEMENT The immunodeficiency chiefly manifests as hypogammaglobulinaemia but involves all elements of the immune system. It is caused by the interpolation of tumour cells among immunological cells and mediated by bi-directional cell contact and secretion of cytokines, which both sustain and invigorate the tumour and suppress immunity. CLL treatment generally makes the immunodeficiency worse. Intravenous immunoglobulin is clinically effective but not cost-effective, while prophylactic antibiotics are useful in appropriate circumstances. Vaccination against infectious disease is usually ineffective. AREAS OF CONTROVERSY Exactly how the presence of tumour cells in the immune organs renders the patient immunodeficient is controversial as is the clinical significance of minor degrees of immunodeficiency in early or indolent cases. The immunosuppressive effect of most forms of treatment is agreed, but how much this should figure in the choice of treatment is a matter of dispute. GROWING POINTS The study of tumour-stromal interactions is an area of intense research. AREAS TIMELY FOR DEVELOPING RESEARCH There has been little done to develop better vaccination strategies in patients with CLL, and although effective antimicrobials have been developed to protect against opportunistic infections, many are both expensive and inconvenient. More work is necessary to define precisely which patients should be offered them and when.
