Hänsel L, Schumacher J, Denis B, Hamane S, Cornely OA, Koehler P. How to diagnose and treat a non-HIV patient with Pneumocystis jirovecii pneumonia (PCP)? Clin Microbiol Infect 2023:S1198-743X(23)00186-6. [PMID: 37086781 DOI: 10.1016/j.cmi.2023.04.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 04/12/2023] [Accepted: 04/13/2023] [Indexed: 04/24/2023]
Abstract
BACKGROUND Pneumocystis jirovecii Pneumonia (PCP) incidence is increasing in non-HIV infected patients. In contrast to PCP in patients infected with HIV, diagnosis is often delayed, and illness is associated with an increased mortality. OBJECTIVE To provide a comprehensive review of clinical presentation, risk factors, diagnostic strategies, and treatment options of PCP in non-HIV-infected patients. SOURCES Web-based literature review on PCP for trials, meta-analyses and systematic reviews using PubMed. Restriction to English language was applied. CONTENT Common underlying conditions in non-HIV-infected patients with PCP are haematological malignancies, autoimmune and inflammatory diseases, solid organ or haematopoietic stem cell transplant and prior exposure to corticosteroids. New risk groups include patients receiving monoclonal antibodies and immunomodulating therapies. Non-HIV-infected patients with PCP present with rapid onset and progression of pneumonia, increased duration of hospitalization and a significantly higher mortality rate than patients infected with HIV. PCP is diagnosed by a combination of clinical symptoms, radiological and mycological features. Immunofluorescence microscopy from bronchoalveolar lavage (BAL) or PCR testing CT imaging and evaluation of the clinical presentation are required. The established treatment regime consists of trimethoprim and sulfamethoxazole. IMPLICATIONS While the number of patients immunosuppressed for other causes than HIV is increasing, a simultaneous rise in PCP incidence is observed. In the group of non-HIV-infected patients, a rapid onset of symptoms, a more complex course, and a higher mortality rate are recorded. Therefore, time to diagnosis must be as short as possible to initiate effective therapy promptly. This review aims to raise awareness of PCP in an increasingly affected at-risk group and provide clinicians with a practical guide for efficient diagnosis and targeted therapy. Furthermore, it intends to display current inadequacies in research on the topic of PCP.

Abstract
Although chronic lymphocytic leukemia (CLL) is a malignancy characterized by accumulation of tumor cells in the blood, bone marrow, lymph nodes and secondary lymphoid tissues, the hallmark of the disease and the major cause of death for patients with CLL is actually immune dysfunction and associated infections. Despite improvement in treatment based on combination chemoimmunotherapy and targeted treatment with BTK and BCL-2 inhibitors leading to longer overall survival for patients with CLL, the mortality due to infections have not improved over the last 4 decades. Thus, infections are now the main cause of death for patients with CLL, posing threats to the patient whether during the premalignant state of monoclonal B lymphocytosis (MBL), during the watch & wait phase for treatment naïve patients, or upon treatment in terms of chemoimmunotherapy or targeted treatment. To test whether the natural history of immune dysfunction and infections in CLL can be changed, we have developed the machine learning based algorithm CLL-TIM.org to identify these patients. The CLL-TIM algorithm is currently being used for selection of patients for the clinical trial PreVent-ACaLL (NCT03868722), testing whether short-term treatment with the BTK inhibitor acalabrutinib and the BCL-2 inhibitor venetoclax can improve immune function and decrease the risk of infections for this high-risk patient population. We here review the background for and management of infectious risks in CLL.

Abstract
Infections are a common cause of morbidity and mortality in patients with lymphoid cancer. With evolving cancer therapeutics, including new targeted and immunotherapies, clinicians need to be aware of additional risk factors and infections that may arise in patients treated with these agents. This "How I Treat" article will highlight fundamental issues including risk factors for infection, infectious diseases screenings and antimicrobial prophylaxis recommendations in patients with lymphoid cancers. We present 4 scenarios of patients with lymphoid cancers with varied infections and describe a treatment approach based on a combination of evidence-based data and experience, as there are limitations in objective infection data especially with newer agents. The goal of this discussion is to provide a framework for institutions and health care providers to develop their own approach in preventing and treating infections in patients with lymphoid cancer.

Abstract
B-cell chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the United States, and its diagnosis can have many dermatologic implications. For one, the cutaneous manifestations of CLL include several entities, most notably leukemia cutis, eosinophilic dermatosis of hematologic malignancy, and a heightened risk of skin infections. Additionally, CLL patients are at an increased risk of secondary malignancies, most commonly of the skin. Furthermore, a number of commonly utilized treatments for CLL have cutaneous implications which should be considered in the interdisciplinary management of CLL patients. In this review, we will provide an update on the diverse cutaneous manifestations of CLL and CLL-directed therapies in order to help guide dermatologic management of this increasingly prevalent patient population.

Abstract
The therapeutic armamentarium for the treatment of patients with lymphoproliferative diseases has grown considerably over the most recent years, including a large use of new immunotherapeutic agents. As a consequence, the epidemiology of infectious complications in this group of patients is poorly documented, and even more importantly, the potential benefit of antimicrobial prophylaxis remains a matter of debate when considering the harmful effect from the emergence of multidrug resistant pathogens. The present position paper is addressed to all hematologists treating patients affected by lymphoproliferative malignancies with the aim to provide clinicians with a useful tool for the prevention of bacterial, fungal and viral infections.

Abstract
OBJECTIVE Opportunistic infections in chronic lymphocytic leukemia (CLL) have been described in clinical trials, single-center studies, and case reports. We performed a nationwide study to estimate the incidence and impact of inpatient opportunistic infections. METHODS The incidence rate (IR) and incidence rate ratio (IRR) for Swedish CLL patients diagnosed 1994-2013, and matched controls were calculated, as well as the case-fatality ratio (CFR). RESULTS Among 8989 CLL patients, a total of 829 opportunistic infections were registered (IR 16.6 per 1000 person-years) compared with 252 opportunistic infections in 34 283 matched controls (IR 0.99). The highest incidence in the CLL cohort was for Pneumocystis pneumonia (200 infections, IR 4.03); Herpes zoster (146 infections, IR 2.94), and Pseudomonas (83 infections, IR 1.66) infections. The highest risk relative to matched controls was observed for Pneumocystis pneumonia (IRR 114, 95% confidence interval 58.7-252). The 60-day CFR for CLL patients with opportunistic infections was 23% (188/821), highest for progressive multifocal encephalopathy (5/7, 71%) and aspergillosis (25/60, 42%). CONCLUSION We have uniquely depicted the incidence of rare and serious infections in CLL patients and found a relatively high incidence of Pneumocystis pneumonia. Of the most common opportunistic infections, CLL patients with aspergillosis had the poorest prognosis.

Abstract
We describe the opportunistic infections occurring in 362 patients with lymphoproliferative disorders treated with ibrutinib and idelalisib in clinical practice. Overall, 108 of 362 patients (29·8%) developed infections, for a total of 152 events. Clinically defined infections (CDI) were 49·3% (75/152) and microbiologically defined infections (MDI) were 50·7% (77/152). Among 250 patients treated with ibrutinib, 28·8% (72/250) experienced one or more infections, for a total of 104 episodes. MDI were 49% (51/104). Bacterial infections were 66·7% (34/51), viral 19·6% (10/51) and invasive fungal diseases (IFD) 13·7% (7/51). Among the 112 patients treated with idelalisib, 32·1% (36/112) experienced one or more infections, for a total of 48 episodes. MDI were 54·2% (26/48). Bacterial infections were 34·6% (9/26), viral 61·5% (16/26) and IFD 3·8% (1/26). With ibrutinib, the rate of bacterial infections was significantly higher compared to idelalisib (66·7% vs. 34·6%; P = 0·007), while viral infections were most frequent in idelalisib (61·5% vs. 19·6%; P < 0·001). Although a higher rate of IFD was observed in patients treated with ibrutinib, the difference was not statistically significant (13·7% vs. 3·8% respectively; P = 0·18). Bacteria are the most frequent infections with ibrutinib, while viruses are most frequently involved with idelalisib.

Abstract
Immune dysregulation in chronic lymphocytic leukemia (CLL) contributes to a high rate of infections and morbidity. The Bruton tyrosine kinase (BTK) inhibitors ibrutinib and acalabrutinib mark major breakthroughs in the treatment of CLL, however many patients require long-term therapy with these agents. Despite receiving effective therapy for CLL, patients on BTK inhibitors remain immunocompromised and at risk of infectious complications. We previously reported that treatment of CLL with ibrutinib leads to partial reconstitution of humoral immunity and fewer infections during the first two years of therapy. It is currently unclear whether the positive effects of ibrutinib on the immune system are sustained during long-term therapy. Acalabrutinib is a newer, more selective BTK inhibitor than ibrutinib; however a detailed evaluation of the immunologic impact of acalabrutinib therapy is lacking. Herein, utilizing two independent trials, we assessed the immunological effects and infectious risk of ibrutinib and acalabrutinib treatment in patients with CLL.

Abstract
This review summarizes the more recent evidence about epidemiology and risk factors for invasive fungal infections (IFI) in patients affected by Chronic Lymphocytic Leukemia (CLL), indolent Non Hodgkin Lymphoma (iNHL) and Multiple Myeloma (MM). Despite advances in the prognosis and treatment of hematological malignancies in recent years, susceptibility to infection remains a significant challenge to patient care. A large amount of data regarding patients with acute leukemia has been published while little information is available on the incidence of IFI in chronic lymphoproliferative disorders (CLD). New drugs are now available for treatment of lymphoproliferative disorders which may cause suppression of humoral immunity, cellular immunity, and deficiency of white blood cells, increasing the risk for infections which remain the leading cause of mortality in these patients.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in Western countries. A common first-line therapy offered to qualifying patients includes ibrutinib, an oral covalent inhibitor of Bruton's tyrosine kinase. Treatment of CLL with ibrutinib therapy is generally well tolerated; however, serious opportunistic infections are being reported in patients treated with ibrutinib. In this report, we present a patient with CLL on ibrutinib therapy who developed rapidly declining neurological status concerning for the central nervous system (CNS) process related to his immunocompromised status. Despite multiple testing modalities, no evidence was found to explain the acute changes the patient was experiencing, and he had no improvement with common antimicrobial coverage. The patient ultimately expired, and autopsy of the brain revealed granulomatous amebic encephalitis due to opportunistic infection by Acanthamoeba species. As evidenced by this case, ibrutinib therapy, despite being generally well tolerated, has the potential to predispose patients to opportunistic infections like amebic encephalitis. Amebic encephalitis is a highly lethal CNS infection, and it is important for clinicians to recognize early on the potential for infection in patients on ibrutinib therapy presenting with CNS symptoms.

Abstract
Aim: A systematic literature review and network meta-analysis were conducted to determine the relative efficacy and safety of interventions for treatment-naive chronic lymphocytic leukemia patients, as comparative evidence is scarce. Materials & methods: Relative treatment effects of progression-free survival, overall survival and safety outcomes were estimated via network meta-analysis based on data identified via systematic literature review. Results: Ibrutinib was superior in all pairwise comparisons for progression-free survival (probability to be better [P] range: overall population: 69–100%; fludarabine-ineligible population: 69–100%) and overall survival (P range: overall: 89–100%; fludarabine-ineligible: 91–100%) and had the highest probability of being best for all outcomes. Conclusion: Ibrutinib provides superior benefit in survival and safety compared with other front-line treatments of chronic lymphocytic leukemia.

Abstract
Therapy-related acute myeloid leukemia (t-AML) is a heterogeneous entity most frequently related to breast cancer or lymphoproliferative diseases (LD). Population-based studies have reported an increased risk of t-AML after treatment of lymphomas. The aim of this study was to describe the characteristics and outcome of 80 consecutive cases of t-AML following treatment of LD. t-AML accounted for 2.3% of all AML cases, occurred 60 months after LD diagnosis, and were characterized by a high frequency of FAB M6 AML and poor-risk cytogenetic abnormalities. Time to t-AML diagnosis was influenced by patient age, type of LD, and treatment. Among the 48 t-AML patients treated with intensive chemotherapy, median overall survival (OS) was 7.7 months compared to 26.1 months in de novo, 4.2 months in post-myeloproliferative neoplasm, 9.4 months in post-myelodysplastic syndrome, 8.6 months in post-chronic myelomonocytic leukemia AML, 13.4 months in t-AML secondary to the treatment of solid cancer, and 14.7 months in breast cancer only. OS of post-LD t-AML patients was significantly influenced by age, performance status, myelodysplastic syndrome prior to LD/t-AML, and treatment regimen for LD. Thus, t-AML following lymphoid malignancies treatment should be considered as very high-risk secondary AML. New treatment strategies in patients with LD/t-AML are needed urgently.

Abstract
Herpes simplex virus (HSV) adenitis is a rare but important cause of morbidity in immunocompromised patients. Chronic lymphocytic leukaemia (CLL)/Small lymphocytic lymphoma (SLL) is an indolent disease which impairs the cellular and humoral immunity, predisposing patients to a myriad of infections. Clinically, herpetic adenitis can mimic large cell (Richter's) transformation in patients with CLL. To date, less than 30 cases of HSV adenitis have been reported in the literature. We report a case of a patient with CLL with no prior history of HSV infection, who presented with rapidly enlarging lymph nodes after initial response to idelalisib raising the suspicion of Richter's transformation. However, excisional biopsy of a lymph node revealed HSV adenitis along with CLL, which was confirmed by immunohistochemical staining.

Abstract
Chronic lymphocytic leukemia (CLL) mainly affects older people: the median age at diagnosis is > 70 years. Elderly patients with CLL are heterogeneous with regard both to the biology of their disease and aging. Following the diagnosis of CLL in an elderly individual, careful risk assessment is essential when treatment options are evaluated. This includes not only clinical staging and evaluation of disease-specific prognostic biomarkers such as 17p deletion and TP53 mutation, but also of comorbidities, physical capacity, nutritional status, cognitive capacity, ability to perform activities of daily living and social support. Comorbidity scoring and geriatric assessment tools are helpful in achieving such multidimensional evaluation in a systematic manner. The introduction of new drugs including novel monoclonal antibodies and kinase inhibitors offers enhanced opportunities for the treatment of elderly patients with CLL. This position paper of a Task Force of the International Society of Geriatric Oncology (SIOG) reviews currently available evidence relevant to such patients. All types of elderly patient (i.e. chronological age > 65-70 years) are considered, from robust (fit) to vulnerable (unfit) to the terminally ill. Among the topics covered are the following: (i) the relationship between chronological age, prognosis and survival, (ii) assessment of biological aging, (iii) biological age as a determinant of treatment feasibility and tolerance and (iv) tailoring of both first and further-line treatment to the circumstances of the individual patient.

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.

Abstract
Data in the literature are lacking regarding the infection-related adverse events of bendamustine-containing regimens. Therefore, we aimed to assess this risk. We conducted a systematic review and meta-analysis of all randomized controlled trials including bendamustine-containing regimens and those administered for any lymphoproliferative disorder or plasma cell dyscrasia compared with any other regimens. A comprehensive search was conducted until December 2015. Two reviewers appraised the quality of trials and extracted data. Primary outcomes were any infections, grade 3 to 4 infections; secondary outcomes were grade 3 to 4 neutropenia and grade 3 to 4 lymphopenia. Relative risks (RRs) with 95% confidence intervals (CIs) were estimated and pooled. A fixed-effect model was used to pool data unless there was significant heterogeneity, in which case a random-effects model was used. Nine trials published between 2006 and 2016 and randomizing 2620 patients were included. There was no statistically significant effect for bendamustine on the rate of any infection (RR 1.09 [95% CI, 0.87-1.36]) or on the rate of grade 3 to 4 infections (RR 1.04 [95% CI, 0.64-1.71]). There was no increase in the rate of grade 3 to 4 neutropenia in the bendamustine arm (RR 0.84 [95% CI, 0.63-1.12]). Our systematic review demonstrates no effect of bendamustine on the rate of infections when compared with either alkylating agents or fludarabine. Thus, bendamustine remains a safe therapeutic option.

Abstract
Because of the widespread use of immunosuppressive drugs, CMV infection is one of the most important causes of morbidity and mortality in patients with haematological malignancies worldwide. The aim of the study was to retrospectively analyse the epidemiology of CMV infection in haematological patients. Between 2008 and 2014, 1238 quantitative CMV DNA detections from plasma specimens were performed. These specimens were collected from 271 patients with haematological malignancy. Patients were grouped on the basis of underlying diseases (lymphoid and myeloid malignancies and other haematological diseases). In the lymphoid and myeloid groups, we distinguished ASCT and non-ASCT groups. During the studied period, the majority of examined patients (82.6 %) were treated with lymphoproliferative disease. A total of 126 (46.5 %) patients underwent ASCT, while 145 (53.5 %) did not have stem cell transplantation. A total of 118 (9.5 %) of 1238 plasma specimens proved to be positive for CMV DNA; these specimens were collected from 66 (24.4 %) patients. Twenty-four (16.6 %) of 145 non-ASCT patients had CMV PCR positive specimens. Among non-ASCT patients with positive CMV PCR results, 10 patients were asymptomatic, 14 had symptomatic reactivation, while 2 had CMV disease. In the ASCT group, 42 (33.3 %) patients had CMV PCR positive samples. CMV reactivation was asymptomatic in 34 (81 %) cases, and 8 (19 %) patients had symptomatic reactivation. In the non-ASCT group, the rate of CMV infection is low. In the ASCT group, the prevalence of CMV infection was higher than in the non-ASCT group, but the majority of CMV infection was asymptomatic and only small number of patients had symptomatic reactivation. Thus, our results also showed that the use of routine CMV DNA monitoring is not necessary in patients with haematological malignancies not receiving fludarabine-containing regimen or alemtuzumab, in spite of this to decrease the mortality we have to consider the use of molecular tests in case of suspected infectious conditions.

Abstract
Bendamustine is being increasingly used in patients with indolent non-Hodgkin lymphoma, mantle cell lymphoma and chronic lymphocytic leukemia. This review summarizes available evidence regarding the effects of bendamustine on the immune system, examines its role in consequent infections as reported in randomized controlled trials, prospective observational investigations, retrospective studies and individual published case reports. Myelosuppression including lymphopenia occurs relatively frequently after therapy with bendamustine. It is mostly CD4 + T cell counts that are suppressed, yet when given in combination with rituximab, both T cell and B cell depletion have been recorded. In addition, hypogammaglobulinemia after bendamustine therapy has also been reported. Variable infection rates have been documented and these include different bacterial, viral and fungal infections. Finally, we also consider issues relating to the use of prophylactic antibiotics in patients receiving the drug.

Abstract
Purpose To describe the health-related quality of life (HRQoL) of an unselected population of patients with chronic lymphocytic leukaemia (CLL) including untreated patients. Methods HRQoL was measured by the EORTC QLQ-C30 including the CLL16 module, EQ-5D, and VAS in an observational study over multiple years. All HRQoL measurements per patient were connected and analysed using area under the curve analysis over the entire study duration. The total patient group was compared with the general population, and three groups of CLL patients were described separately, i.e. patients without any active treatment (“watch and wait”), chlorambucil treatment only, and patients with other treatment(s). Results HRQoL in the total group of CLL patients was compromised when compared with age- and gender-matched norm scores of the general population. CLL patients scored statistically worse on the VAS and utility score of the EQ-5D, all functioning scales of the EORTC QLQ-C30, and the symptoms of fatigue, dyspnoea, sleeping disturbance, appetite loss, and financial difficulties. In untreated patients, the HRQoL was slightly reduced. In all treatment stages, HRQoL was compromised considerably. Patients treated with chlorambucil only scored worse on the EORTC QLQ-C30 than patients who were treated with other treatments with regard to emotional functioning, cognitive functioning, bruises, uncomfortable stomach, and apathy. Conclusions CLL patients differ most from the general population on role functioning, fatigue, concerns about future health, and having not enough energy. Once treatment is indicated, HRQoL becomes considerably compromised. This applies to all treatments, including chlorambucil, which is considered to be a mild treatment.

Abstract
The introduction of novel agents to the therapeutic armamentarium for oncologic, rheumatologic, and neurologic disorders has resulted in major clinical advances. These agents impact immune function, resulting in a discrete spectrum of infectious complications. Purine analogues and alemtuzumab alter cell-mediated immunity, resulting in opportunistic viral/fungal infections. Herpes zoster incidence increases with bortezomib. Hepatitis B reactivation may occur with rituximab. Cases of progressive multifocal leukoencephalopathy have occurred following monoclonal antibody therapy. Tumor necrosis factor-α inhibitor therapy is complicated by tuberculosis reactivation and fungal infections. We summarize the impact of these therapies on pathogenesis and spectrum of infection complicating their usage.

Abstract
A multi-center retrospective analysis of a cohort of patients in Israel treated with any bendamustine containing regimen between 2010-2014 was performed in order to determine the incidence and predictors for infection. The Kaplan Meier Model, employing log rank analysis, was used to assess time-to-infection. The Cox Proportional Hazards model was used to analyze multivariate effects of risk and 234 patients were included in the analysis. One hundred and nine (46.6%) developed at least one infection and 33.76% had severe infections. Seventy-six (41.5%) developed bacterial infection, nine (3.8%) fungal infection and 26 (11.5%) had viral infections. Factors significantly associated with time to infection on multivariable analysis were: bendamustine-combinations [hazard ratio (HR) = 0.589 (95% CI = 0.374-0.926), p = 0.022], Hb level [HR = 0.791 (95% CI = 0.716-0.875), p < 0.0001] and ischemic heart disease [HR = 1.828 (95% CI = 1.165-2.868), p = 0.009]. Infections were associated with a higher mortality and hospitalization rate.

Abstract
Infectious complications are a major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL) due to impaired immunity secondary to the disease itself and to the immunosuppressive therapies administered to these patients. We report a 78-year-old woman with CLL who was treated with steroids for autoimmune hemolytic anemia (AIHA). A few weeks later, she was admitted for severe acute hepatitis with disseminated intravascular coagulation (DIC). Despite the symptomatic treatment of DIC, standard reanimation and probabilistic antibiotics, the patient died within 24h with severe hepatic failure. Autopsy was in favor of a disseminated viral infection with esophageal, hepatic and pulmonary cytopathologic lesions with acidophilic intranuclear inclusions suggestive of herpes virus, even though HSV 1 and 2, CMV and HHV6 PCRs were negative. This case of severe viral hepatitis with esophagitis occurring three weeks after the introduction of high-dose steroid treatment for AIHA in a CLL patient calls for anti-herpetic prophylaxis in such patients, immunodepressed by their diseases and the treatment they receive.

Abstract
Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of CD5+CD19+ B cells in the peripheral blood, and in primary and secondary lymphoid organs. A major complication associated with CLL is severe recurrent infections, which are often fatal. Vulnerability to infection is due to a wide variety of immunological defects, yet the initiating events of immunodeficiency in CLL are unclear. Using CLL patient samples and a mouse model of CLL, we have discovered that plasmacytoid dendritic cells (pDCs), which underpin the activity of effector immune cells critical for anti-viral immunity and anti-tumor responses, are reduced in number and functionally impaired in progressive CLL. As a result, the levels of interferon alpha (IFNα) production, a cytokine critical for immunity, are markedly reduced. Lower pDC numbers with impaired IFNα production was due to the decreased expression of FMS-like tyrosine kinase 3 receptor (Flt3) and Toll-like receptor 9 (TLR9), respectively. Reduced Flt3 expression was reversed using inhibitors of TGF-β and TNF, an effect correlating with a reduction in tumor load. Defects in pDC numbers and function offer a new insight into mechanisms underpinning the profound immunodeficiency affecting CLL patients and provide a potentially novel avenue for restoring immuno-competency in CLL.

Abstract
Chlorambucil is an alkylating agent commonly used in treatment of chronic lymphocytic leukemia (CLL). We report a case of interstitial pneumonitis developing in an 83-year-old man 1.5 months after completing a six-month course of chlorambucil for CLL. The interstitial pneumonitis responded to therapy with prednisone. We performed a systematic review of literature and identified 13 other case reports of chlorambucil-induced pulmonary toxicity, particularly interstitial pneumonitis. No unifying risk factor could be discerned and the mechanism of injury remains unknown. In contrast, major randomized trials of chlorambucil therapy in CLL have not reported interstitial pneumonitis as an adverse effect, which may be due to the rarity of the phenomenon or due to underreporting of events occurring after completion of treatment. Clinicians should consider drug-induced interstitial pneumonitis in the differential diagnosis of a suggestive syndrome developing even after discontinuation of chlorambucil.

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
Fludarabine-based regimens and CHOP (doxorubicin, cyclophosphamide, vincristine, prednisone)-like regimens with or without rituximab are the most common treatment modalities for indolent lymphoma. However, there is no clear evidence to date about which chemotherapy regimen should be the proper initial treatment of indolent lymphoma. More recently, the use of fludarabine has raised concerns due to its high number of toxicities, especially hematological toxicity and infectious complications. The present study aimed to retrospectively evaluate both the efficacy and the potential toxicities of the two main regimens (fludarabine-based and CHOP-like regimens) in patients with previously untreated indolent lymphoma. Among a total of 107 patients assessed, 54 patients received fludarabine-based regimens (FLU arm) and 53 received CHOP or CHOPE (doxorubicin, cyclophosphamide, vincristine, prednisone, or plus etoposide) regimens (CHOP arm). The results demonstrated that fludarabine-based regimens could induce significantly improved progression-free survival (PFS) compared with CHOP-like regimens. However, the FLU arm showed overall survival, complete response, and overall response rates similar to those of the CHOP arm. Grade 3–4 neutropenia occurred in 42.6% of the FLU arm and 7.5% of the CHOP arm (P < 0.000). Moreover, the FLU arm also had a higher occurrence of infection than the CHOP arm (27.8% vs 8.5%; P = 0.034). Multi-factor regression of infection revealed that only age (>60 years) and presentation of grade 3–4 myelosuppression were the independent factors to infection, and the FLU arm had significantly higher myelosuppression. In conclusion, the present study revealed that the use of fludarabine-based regimens could induce high rates of myelosuppression over CHOP-like regimens, in spite of significant increases in PFS.

Abstract
UNLABELLED Rituximab targets normal B cells and tumor B cells. We used a unique data-mining tool to identify patients with lymphoma who were treated with rituximab and who had serial pre and post rituximab immunoglobulin concentrations evaluated. After treatment, 39% (69/179) of patients had low levels of immunoglobulin G. Recurrent sinopulmonary infections were seen in 6.6% (14/211). Intravenous immune globulin appeared to reduce the frequency of infection. BACKGROUND Rituximab has altered the treatment approach to B-cell malignancies and other diseases. Reports consider that rituximab had limited impact on serum immunoglobulins. However, anecdotes suggest that rituximab can cause symptomatic hypogammaglobulinemia. This retrospective study examined the relationship among rituximab, hypogammaglobulinemia, and treatment of symptomatic hypogammaglobulinemia with intravenous immune globulin (IVIG). METHODS Patients with serial quantitative serum immunoglobulin (SIgG) concentrations before and subsequent to rituximab administration at Memorial Sloan-Kettering Cancer Center were identified. Information regarding rituximab administration, SIgG concentrations, frequency of infection, and administration of IVIG were recorded. RESULTS Between December 1998 and April 2009, 211 patients with B-cell lymphoma treated with rituximab and with serial SIgG concentrations were identified. One hundred seventy-nine (85%) patients had normal SIgG before rituximab, 32 (15%) had low SIgG. After rituximab use, hypogammaglobulinemia was identified in 38.54% of patients with initially normal SIgG. The risk was greater in patients who received maintenance rituximab. Symptomatic hypogammaglobulinemia that prompted IVIG administration developed in 6.6% of patients. CONCLUSIONS In this data set, rituximab administration was associated with a high frequency of hypogammaglobulinemia, particularly symptomatic hypogammaglobulinemia, among patients who received multiple courses of rituximab. Baseline and periodic monitoring of SIgGs is appropriate in patients who receive rituximab.

Abstract
Infectious complications have been known to be a major cause of morbidity and mortality in Chronic Lymphocytic Leukemia (CLL) patients who are prone to infections because of both the humoral immunodepression inherent to the hematologic disease and to the immunosuppression related to the therapy. The majority of infections in CLL patients treated with alkilating agents is of bacterial origin. The immunodeficiency and natural infectious history of alkylator-resistant, corticosteroid-treated patients appears to have changed with the administration of purine analogs, which has been complicated by very severe and unusual infections and also more viral infections due to sustained reduction of CD4-positive T lymphocytes. The subsequent introduction of monoclonal antibodies in therapies, in particular alemtuzumab, further increased the immunodepression, increasing also infections which appeared more often in patients with recurrent neutropenia due to chemotherapy cycles.Epidemiological data regarding fungal infections in lymphoproliferative disorders are scarce. Italian SEIFEM group in a retrospective multicentre study regarding CLL patients reported an incidence of mycoses 0.5%; however, chronic lymphoproliferative disorders emerged as second haematological underlying disease after acute leukemia in a French study on aspergillosis; in particular CLL with aspergillosis accounted for a third of these chronic lymphoproliferative diseases presenting mould infection.

Abstract
BACKGROUND Scientific literature on infectious complications of chemotherapy in lymphomas is often based on retrospective studies or clinical trials performed with selected patients. This population may not be representative of the routine clinical practice. We aimed to analyse the incidence and type of infections associated to standard chemotherapy in clinically aggressive mature B and T cell lymphomas (AMBTL) and to detect baseline variables predictive of the risk of infection in a cohort of unselected patients. METHODS A prospective observational study of all the patients treated with first line chemotherapy for AMBTL in our Lymphoma Unit, in the setting of a community based teaching hospital, was performed. The statistical methods were univariate and multivariate analyses. RESULTS 183 infectious episodes were registered in 97 (49%) of the 198 patients. Seventy-nine of them (43%) were associated to febrile neutropenia (27% of the patients). Microbiological documentation was obtained in 46% and only clinical documentation in 15%; 39% were classified as fever of unknown origin. Gram negative bacilli were the predominant aetiology. There were several variables related to risk of infection, but in multivariate analysis only a poor initial performance status was predictive of the risk of febrile neutropenia and infection during the first line chemotherapy. CONCLUSIONS In our cohort of AMBTL patients treated with first line chemotherapy, more than half of the relevant infections occurred without febrile neutropenia. A poor performance status was the only independent variable associated with the risk of febrile neutropenia or infection in the course of first line chemotherapy.

Abstract
BACKGROUND Chronic lymphocytic leukemia (CLL) patients are at high risk for acute respiratory illness (ARI). OBJECTIVE We evaluated the safety and efficacy of a proprietary extract of Panax quinquefolius, CVT-E002, in reducing ARI. METHODS This was a double-blind, placebo-controlled, randomized trial of 293 subjects with early-stage, untreated CLL conducted January-March 2009. RESULTS ARI was common, occurring on about 10% of days during the study period. There were no significant differences of the 2 a priori primary end points: ARI days (8.5 ± 17.2 for CVT-E002 vs 6.8 ± 13.3 for placebo) and severe ARI days (2.9 ± 9.5 for CVT-E002 vs 2.6 ± 9.8 for placebo). However, 51% of CVT-E002 vs 56% of placebo recipients experienced at least 1 ARI (difference, -5%; 95% confidence interval [CI], -16% to 7%); more intense ARI occurred in 32% of CVT-E002 vs 39% of placebo recipients (difference, -7%; 95% CI, -18% to 4%), and symptom-specific evaluation showed reduced moderate to severe sore throat (P = .004) and a lower rate of grade ≥3 toxicities (P = .02) in CVT-E002 recipients. Greater seroconversion (4-fold increases in antibody titer) vs 9 common viral pathogens was documented in CVT-E002 recipients (16% vs 7%, P = .04). LIMITATIONS Serologic evaluation of antibody titers was not tied to a specific illness, but covered the entire study period. CONCLUSION CVT-E002 was well tolerated. It did not reduce the number of ARI days or antibiotic use; however, there was a trend toward reduced rates of moderate to severe ARI and significantly less sore throat, suggesting that the increased rate of seroconversion most likely reflects CVT-E002-enhanced antibody responses.

Abstract
PURPOSE The standard of care and novel treatments for chronic lymphocytic leukemia (CLL) are reviewed. SUMMARY Recent advances in the treatment of CLL have dramatically changed the therapeutic landscape for both patients and health care professionals. The majority of conventional first-line therapies are noncurative and are only used to treat disease that is symptomatic or progressive and include chlorambucil, monotherapy with purine analogues, and combination chemotherapy. Immunotherapeutic agents such as rituximab and alemtuzumab may be indicated in select patient populations. However, because clinical trials have found that overall survival does not depend on the initial therapy, selection of first-line therapy should be based on patient-specific factors and the patient's goals for therapy with respect to response, survival, and symptom palliation. Progression-free survival time and time to treatment are critical endpoints for CLL treatment. An increasingly important endpoint is minimal residual disease (MRD), as it is considered to be the major cause of relapse in CLL. Finally, comparison of toxicities between different therapies is critical in CLL, as it is in other disease states. Several new agents are currently being evaluated for use in CLL, including alvocidib, oblimersen, and lumiliximab. CONCLUSION Chemotherapy remains the mainstay of treatment for the majority of patients with CLL. The introduction of rituximab, alemtuzumab, and bendamustine has improved the current outlook for patients with CLL. As overall survival does not appear to depend on the initial therapy, treatment should be selected based on patient-specific factors and goals. Challenges in CLL include determining when to initiate therapy, eradicating MRD, and managing therapeutic resistance.

The pathogenesis of infections in these patients is multifactorial, related to inherent immune defects and therapy-related immunosuppression. Hypogammaglobulinaemia is an important predisposing factor for infection in all patients. The use of the purine analogues such as fludarabine, and monoclonal antibodies such as rituximab and alemtuzumab, has introduced a new spectrum of infectious complications caused by pathogens such as Pneumocystis, Listeria, mycobacteria, herpesviruses Candida and Aspergillus, related to the cellular immune suppression induced by these agents. This review focuses on the pathogenesis and risk factors for infections in patients with CLL, the spectrum of infectious complications and preventive approaches to infection in these patients, using antimicrobial and immunoglobulin prophylaxis and vaccination strategies.

Abstract
There have been tremendous advances in the treatment of chronic lymphocytic leukemia (CLL) over the past decade, with the goal of therapy no longer being just to palliate symptoms but now to achieve complete remission, eradicate minimal residual disease, and improve survival. During this period, there have also been major advances in identification of molecular factors associated with increased risk of progression. The clinical utility of these factors is being explored to determine whether we can identify groups of patients who should be treated earlier in their disease course and whether we can tailor therapy for groups of patients with specific molecular markers of disease. First-line chemoimmunotherapy approaches now offer prolonged survival, and there is a need to identify patients who are suitable candidates for allogeneic stem-cell transplantation that uses reduced-intensity conditioning regimens. The vast majority of CLL patients are either too old or do not have sufficiently high-risk disease to warrant these approaches, and effective therapies that can be tolerated by the more frail elderly patients with this disease are urgently needed. Numerous novel agents are being developed, and their role in the first-line treatment of frail patients or those who relapse after previous treatment is being explored in clinical trials.

Kelesidis T, Daikos G, Boumpas D, Tsiodras S. Does rituximab increase the incidence of infectious complications? A narrative review. Int J Infect Dis 2010; 15:e2-16. [PMID: 21074471 DOI: 10.1016/j.ijid.2010.03.025] [Citation(s) in RCA: 146] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2009] [Revised: 03/23/2010] [Accepted: 03/30/2010] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Rituximab has increasingly been used for the treatment of hematological malignancies and autoimmune diseases, and its efficacy and safety are well established. Although clinical trials have shown conflicting results regarding the association of rituximab with infections, an increased incidence of infections has recently been reported in patients with lymphomas being treated with rituximab. However, clinical experience regarding the association of rituximab with different types of infection is lacking and this association has not been established in patients with rheumatoid arthritis. METHODS All previous studies included in our literature review were found using a PubMed, EMBASE, and Cochrane database search of the English-language medical literature applying the terms 'rituximab', 'monoclonal antibodies', 'infections', 'infectious complications', and combinations of these terms. In addition, the references cited in these articles were examined to identify additional reports. RESULTS We performed separate analyses of data regarding the association of rituximab with infection in (1) patients with hematological malignancies, (2) patients with autoimmune disorders, and (3) transplant patients. Recent data show that rituximab maintenance therapy significantly increases the risk of both infection and neutropenia in patients with lymphoma or other hematological malignancies. On the other hand, data available to date do not indicate an increased risk of infections when using rituximab compared with concurrent control treatments in patients with rheumatoid arthritis. However, there is a lack of sufficient long-term data to allow such a statement to be definitively made, and caution regarding infections should continue to be exercised, especially in patients who have received repeated courses of rituximab, are receiving other immunosuppressants concurrently, and in those whose immunoglobulin levels have fallen below the normal range. Few data are available concerning the risk of organ transplant recipients developing infections following rituximab therapy. Data from case reports, case series, and retrospective studies correlate rituximab use with the development of a variety of infections in transplant patients. CONCLUSIONS Further studies are needed to clarify the association of rituximab with infection. Physicians and patients should be educated about the association of rituximab with infectious complications. Monitoring of absolute neutrophil count and immunoglobulin levels and the identification of high-risk groups for the development of infectious complications, with timely vaccination of these groups, are clearly needed.

HBV reactivation after fludarabine chemotherapy identified on investigation of suspected transfusion-transmitted Hepatitis B virus. J Hepatol 2010; 53:780-7.

Abstract
BACKGROUND & AIMS Multi-transfused patients often receive treatments inducing various levels of immunodeficiency. Acute viral infections may then be attributed either to transfusion-transmitted infection (TTI) or reactivation of a past infection. METHODS A patient with chronic lymphocytic leukemia (CLL) who had >250 blood donor exposures developed acute Hepatitis B virus (HBV) infection. Routine donor testing for HB core antibodies (anti-HBc) was in place in the relevant period and investigations undertaken on the blood donors were negative. RESULTS Review of historical, molecular, and antigenic evidence demonstrated reactivation of a recovered HBV infection dating >30 years and the selection of a rare escape mutant that briefly replicated and caused acute liver disease. This mutant was unreactive with several HBsAg assays and poorly reactive with an HBV vaccine plasma. Correcting the C139Y substitution by site directed mutagenesis of recombinant surface proteins re-established assay reactivity. CONCLUSIONS Fludarabine, but not Chlorambucil, appeared sufficiently immunosuppressive to trigger reactivation despite low levels of neutralizing antibodies. Differentiating between TTI and reactivation of HBV becomes more challenging with the increasing frequency of immunocompromised blood recipients. Chemotherapy with Fludarabine alone should be considered as carrying high risk of viral reactivation. Pre-treatment testing and peripheral blood sample archiving may be indicated in HBsAg negative patients.

Abstract
BACKGROUND JC virus (JCV), a polyoma virus, is the etiological agent of progressive multifocal leukoencephalopathy in immunosuppressed patients. JCV T-Ag has proven oncogenic potential and is expressed in colonic polyps and carcinomas. We proposed that the prevalence of JCV T-Ag DNA is higher in the normal gastrointestinal (GI) mucosa of immunosuppressed patients compared with their immunocompetent counterparts. AIMS To look for JCV T-Ag DNA in the normal gastrointestinal mucosa of immunosuppressed patients compared with immunocompetent controls. METHODS Macroscopically normal samples of upper and lower GI mucosa were obtained from 38 immunosuppressed patients. A control group included samples from 19 immunocompetent inflammatory bowel disease (IBD) and 29 non-IBD cases. DNA was extracted and polymerase chain reaction (PCR) was performed using primers specific for T-Ag. RESULTS JCV T-Ag DNA was found in nine of the immunosuppressed patients (23.7%) and in three of the controls (6.3%; P = 0.02). Transplant recipients had a particularly high prevalence of JCV T-Ag DNA (35.3%). Patients with IBD receiving immunosuppressive drugs had a higher prevalence of JCV T-Ag DNA in comparison with IBD patients who did not receive immunosuppression (22.2% versus 10.5%, respectively), but this difference was not statistically significant (P = 0.574). CONCLUSION JCV T-Ag DNA is more prevalent in the upper and lower GI mucosa of immunosuppressed patients, possibly indicating that the virus resides in these patients. This may account for the higher prevalence of GI carcinomas in immunosuppressed patients.

Abstract
Infections continue to be a major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL), as therapeutic advances have occurred over the past several decades. The pathogenesis of infection in these patients is multifactorial, including inherent immune defects related to the primary disease process, such as hypogammaglobulinemia, as well as therapy-related immunosuppression. A characteristic spectrum of infectious complications has been described for specific treatment agents. With chlorambucil, most infections are bacterial in origin, caused by common Gram-positive and -negative organisms. Recurrent infections are a hallmark, with the respiratory tract being the most common site of infection. The pathogenesis of infection with the purine analogues is related to the quantitative and qualitative T-cell abnormalities induced by these agents. Risk factors for infection identified in patients treated with fludarabine include advanced-stage disease, prior CLL therapy, response to therapy, elevated serum creatinine, hemoglobin < 12 g/dL, and decreased serum IgG. As compared with patients receiving chlorambucil, patients receiving fludarabine have more major infections and herpes virus infections. However, Pneumocystis, Aspergillus, and cytomegalovirus (CMV) infections are uncommon. The use of alemtuzumab is complicated by frequent opportunistic infections. CMV reactivation is especially problematic, occurring in 10%-25% of patients. For prevention of infection, the use of vaccinations and immunoglobulin replacement has been studied. Recommendations for prophylactic antimicrobial therapy have arisen from CLL treatment trials and anecdotal reports. As new treatment approaches are developed for CLL, one must consider not only the efficacy of these agents for disease response but also the effect on subsequent infectious complications. Infectious complications remain a significant cause of morbidity and mortality in patients with CLL. We will review the pathogenesis as well as the spectrum of infections in these patients. We will also discuss approaches to the prophylactic and therapeutic management of infections in these patients.

Abstract
Although chronic lymphocytic leukemia (CLL) remains incurable, over the past decade there have been major advances in understanding the pathophysiology of CLL and in the treatment of this disease. This has led to greatly increased response rates and durations of response but not yet improved survival. Advances in the use of prognostic factors that identify patients at high risk for progression have led us to the question whether there is still a role for a "watch and wait" approach in asymptomatic high-risk patients or whether they should be treated earlier in their disease course. Questions remain, including, what is the optimal first-line treatment and its timing and is there any role of maintenance therapy or stem cell transplantation in this disease? CLL is a disease of the elderly and not all patients are eligible for aggressive up-front chemoimmunotherapy regimens, so what is the optimal treatment approach for more frail elderly patients? It is highly likely that our treatment approaches will continue to evolve as the results of ongoing clinical trials are released and that further improvements in the outcome of this disease will result from identification of therapies that target the underlying pathophysiology of CLL.

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.
