Abstract
Despite the widespread use of combined antiretroviral therapy (cART) and the subsequent decrease in AIDS-defining cancers, HIV-related lymphomas remain a leading cause of morbidity and mortality in people with HIV (PWH). Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma (NHL) subtype in PWH. This lymphoma is a heterogeneous disease including morphological variants and molecular subtypes according to the cell of origin or the mutation profile. In the pre-cART era, treatment with standard-dose chemotherapy induced high rates of toxicity and outcomes were very poor. The introduction of cART and the incorporation of infection prophylaxis allowed the use of conventional intensive chemotherapy regimens used in the general population, such as R-CHOP or R-EPOCH. The use of cART during chemotherapy treatment was initially controversial due to the potential risk of adverse drug-drug interactions. However, the availability of current cART regimens with less potential to cause drug interactions and evidence that cART improves survival rates in NHL strongly support the use of cART in PWH with DLBCL. Consequently, interdisciplinary collaboration between HIV specialists and hemato-oncologists for the management of potential interactions and overlapping toxicities between antiretroviral and antineoplastic drugs is crucial for the optimal treatment of PWH with NHL.

Hodgkin Lymphoma in People Living with HIV. Cancers (Basel) 2021; 13:cancers13174366.

Abstract
Simple Summary Hodgkin lymphoma (HL) is a non-AIDS defining neoplasm, but people living with HIV (PLWH) have between a 5- and 26-fold higher risk of developing it than the general population. Epstein-Barr virus is present in almost all HIV-related HL cases, and plays an important role in its etiopathogenesis. Despite the aggressive characteristics, the prognosis of HL affecting PLWH is similar to that of the general population if patients are treated following the same recommendations. Administration of cART concomitantly with chemotherapy is highly recommended. However, this combination may be challenging due to drug–drug interactions and overlapping toxicity. Thus, interdisciplinary collaboration between hemato-oncologists and HIV specialists is crucial for the optimal treatment of both lymphoma and HIV infection. Abstract Despite widespread use of combined antiretroviral therapy (cART) and increased life expectancy in people living with HIV (PLWH), HIV-related lymphomas (HRL) remain a leading cause of cancer morbidity and mortality for PLWH, even in patients optimally treated with cART. While the incidence of aggressive forms of non-Hodgkin lymphoma decreased after the advent of cART, incidence of Hodgkin lymphoma (HL) has increased among PLWH in recent decades. The coinfection of Epstein–Barr virus plays a crucial role in the pathogenesis of HL in the HIV setting. Currently, PLWH with HRL, including HL, are treated similarly to HIV-negative patients and, importantly, the prognosis of HL in PLWH is approaching that of the general population. In this regard, effective cART during chemotherapy is strongly recommended since it has been shown to improve survival rates in all lymphoma subtypes, including HL. As a consequence, interdisciplinary collaboration between HIV specialists and hemato-oncologists for the management of potential drug–drug interactions and overlapping toxicities between antiretroviral and antineoplastic drugs is crucial for the optimal treatment of PLWH with HL. In this article the authors review and update the epidemiological, clinical and biological aspects of HL presenting in PLWH with special emphasis on advances in prognosis and the factors that have contributed to it.

Abstract
Objective: To describe data with selected malignancies in people living with HIV (PLWH) and HIV in individuals affected by both conditions and to summarize drug-drug interactions (DDIs) with clinical recommendations for point-of-care review of combination therapies. Data Sources: Literature searches were performed (2005 to December 2018) in MEDLINE and EMBASE to identify studies of malignancies in PLWH in the modern era. Study Selection and Data Extraction: Article bibliographies and drug interaction databases were reviewed. Search terms included HIV, antiretroviral therapy, antineoplastic agents, malignancies, and drug interactions. Data Synthesis: In the pre-antiretroviral therapy (ART) era, malignancies in PLWH were AIDS-defining illnesses, and life expectancy was shorter. Nowadays, PLWH are living longer and developing malignancies, including lung, anal, and prostate cancers. Concurrently, the oncology landscape has evolved, with novel oral targeted agents and immunotherapies becoming routine elements of care. The increased need for and complexity with antineoplastics in PLWH has led to recommendations for multidisciplinary care of this unique population. Evaluation of DDIs requires review of metabolic pathways, absorption mechanisms, and various drug transporters associated with antineoplastics and ART. Relevance to Patient Care and Clinical Practice: This review summarizes available data of non-AIDS-defining malignancies, principles of HIV care in the patient with malignancy, and guidance for assessing DDIs between antineoplastics and ART. Summary DDI tables provide point-of-care recommendations. Conclusions: The availability of ART has transformed AIDS into a chronic medical condition, and PLWH are experiencing age-related malignancies. Pharmacists play an important role in the management of this patient population.

Outcome effects of antiretroviral drug combinations in HIV-positive patients with chemotherapy for lymphoma: a retrospective analysis. Int J Clin Pharm 2018; 40:1402-1408. [PMID: 29948741 PMCID: PMC6208603 DOI: 10.1007/s11096-018-0620-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2017] [Accepted: 03/15/2018] [Indexed: 12/22/2022]
Abstract
Background The combination of combined active antiretroviral therapy (cART) with chemotherapy in the treatment of lymphoma in human immunodeficiency virus (HIV)-positive patients has improved the overall survival of these patients. However, drug–drug interactions between antineoplastic agents and the antiretroviral agents non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs) can occur by influencing the activity of the CYP3A4 enzyme. So far, little is known about the clinical relevance of this interaction: the effect on the efficacy and toxicity of the chemotherapy. Also, there is no general consensus which cART is preferable in combination with antineoplastic drugs. Objective To compare PI-based with NNRTI-based cART on the efficacy and toxicity of chemotherapy in lymphoma patients. Setting The Onze Lieve Vrouwe Gasthuis, located in Amsterdam, The Netherlands. Method A retrospective observational cohort study including all patients with HIV and lymphoma over a 10-year period. Clinical outcome (response to chemotherapy and survival) and toxicity of chemotherapy (renal, hepatic and bone marrow toxicity as well as dose reduction, treatment delay and discontinuation) was compared in patients with PI based and NNRTI-based cART. Main outcome measure: Response to chemotherapy and survival. Results Patients using PI-based cART (n = 22) had a significantly lower 1 year survival compared to NNRTI-based cART (n = 21). No significant differences were observed in reaching complete remission after chemotherapy. No overall significant differences in toxicity and discontinuation of the chemotherapy were observed. However, there was a trend towards more severe bone-marrow toxicity in patients with PI-based cART. In addition, patients with PI-based cART received earlier dose-reduction and treatment delay, indicating increased toxicity in PI-treated patients. Conclusion This retrospective study shows that PI-based cART is inferior in combination with chemotherapy to NNRTI-based cART: a lower 1 year survival is observed and dose-reduction and treatment delay occur earlier, possibly based on an earlier onset of toxicity.

Abstract
Background Co-administration of antineoplastics with ART is challenging due to potential drug-drug interactions (DDIs). However, trials specifically assessing such DDIs are lacking. Our objective was to simulate DDIs between the antineoplastics erlotinib and gefitinib with key antiretroviral drugs and to predict dose adjustments using a physiologically based pharmacokinetic (PBPK) model. Methods In vitro data describing chemical properties and pharmacokinetic processes of each drug and their effect on cytochrome P450 isoforms were obtained from the literature. Plasma drug-concentration profiles were simulated in a virtual population of 50 individuals receiving erlotinib or gefitinib alone or with darunavir/ritonavir, efavirenz or etravirine. Simulated pharmacokinetic parameters and the magnitude of DDIs with probe drugs (midazolam, maraviroc) were compared with literature values. Erlotinib and gefitinib pharmacokinetics with and without antiretrovirals were compared and dose-adjustment strategies were evaluated. Results Simulated parameters of each drug and the magnitude of DDIs with probe drugs were in agreement with reference values. Darunavir/ritonavir increased erlotinib and gefitinib exposure, while efavirenz and etravirine decreased erlotinib and gefitinib concentrations. Based on our predictions, dose-adjustment strategies may consist of once-daily dosing erlotinib at 25 mg and gefitinib at 125 mg with darunavir/ritonavir; or erlotinib at 200 mg and gefitinib at 375 mg with etravirine. The interaction with efavirenz was not overcome even after doubling erlotinib or gefitinib doses. Conclusions PBPK models predicted the in vivo pharmacokinetics of erlotinib, gefitinib and the antiretrovirals darunavir/ritonavir, efavirenz and etravirine, and the DDIs between them. The simulated dose-adjustments may represent valuable strategies to optimize antineoplastic therapy in HIV-infected patients.

Abstract
The advent of combination antiretroviral treatment (cART) has been followed by a decrease in HIV-associated morbidity and mortality, but also by an apparent increase in the incidence of non-AIDS-defining cancers (NADCs). The risk of lung cancer is substantially higher in HIV-infected patients than in the general population, in part due to aging and tobacco use, and it is the most frequent NADC. The management of lung cancer in HIV-infected patients has some peculiarities that need to be taken into account. This review focuses on the epidemiology, risk factors, and clinical management of lung cancer in HIV-infected patients. In addition, screening tools and future perspectives are also discussed.

Abstract
In human immunodeficiency virus (HIV)-infected persons, the incidence of hematologic malignancies, including leukemia and lymphoma, is increased despite the use of successful antiretroviral therapy. Hematopoietic stem cell transplantation (SCT) is emerging as a safe and effective therapy for HIV-infected persons with hematologic malignancies. Management of these patients is complicated by drug-drug interactions involving antiretroviral therapy (ART) that may impact conditioning agent efficacy and metabolism of immunosuppressive medications and potentiate drug toxicities. As such, optimal strategies for ART remain controversial. We discuss recent advances, controversies, and future directions related to SCT in HIV-infected persons, including the investigation of allogeneic SCT as a strategy for HIV cure.

Abstract
Highly active antiretroviral therapy (HAART) has dramatically improved the morbidity and mortality of patients with HIV. Although the incidence of AIDS-defining neoplasms is decreasing with this therapy, they must still be considered in patients who present with suspicious symptoms. Early diagnosis and treatment may help to improve quality of life and clinical outcome. We report the case of a 30-year-old man on HAART who presented with an expanding lump in the left groin, thought to be a haematoma for 5 months. A high level of suspicion led to a prompt diagnosis of Burkitt's lymphoma followed by timely treatment with chemotherapy. This culminated in complete remission, with an improved quality of life.

Abstract
The optimal antiretroviral therapy (ART) regimen for human immunodeficiency virus (HIV)-infected patients with cancer remains unknown, as clinical trials are lacking and published data are insufficient to guide recommendations. When concomitant use of chemotherapy and ART is anticipated, overlap of toxic effects and drug-drug interactions between chemotherapy and ART may alter the optimal choice of ART. Prospective studies are urgently needed to further define the toxic effects of combined chemotherapy and ART in HIV-positive cancer patients. Such studies should aid the development of guidelines for treatment of this population. For now, clinicians should individualize decisions regarding treatment of HIV according to clinical and laboratory findings, cancer treatment plan (chemotherapy, radiotherapy, or surgery), liver or renal disease, potential adverse drug effects (eg, rash, gastrointestinal intolerance, bone marrow suppression), and patient preference. This review focuses on what infectious disease specialists need to know to select the most appropriate ART regimens for patients receiving chemotherapy.

Abstract
Data from Italy, Spain and the USA all highlight the worrying fact that presentation with advanced HIV disease - defined as a cluster of differentiation 4 (CD4) count <50 cells/mm(3) or the presence of an acquired immunodeficiency syndrome-defining illness - is increasingly common. A review from 2003 showed that 31% of patients in the UK and Ireland presented late (<200 CD4 cells/mm(3)). Early diagnosis is vital to ensure that patients benefit from antiretroviral therapy, and when patients present late, they do not obtain the benefits of early treatment. The risk of death is lower when antiretroviral therapy is initiated at CD4 counts of 201-350 cells/mm(3) than at lower CD4 cell counts. In addition, the risk of unintentional infection of others is increased, which is particularly troubling in light of evidence that transmission of resistance can occur even in the absence of antiretroviral therapy. The management of patients with advanced disease and no complications is complex, but issues of transmitted resistance and comorbid conditions further confuse management decisions in the treatment of patients with higher CD4 counts. This article reviews recent evidence on transmitted resistance, the pharmacokinetics of antiretroviral drugs in patients with central nervous system disease and the management issues in patients with comorbid malignancies to offer practical advice on therapeutic options for treatment-naïve patients who present with advanced HIV disease.

Abstract
Few genetic markers are used routinely to predict clinical effectiveness and toxic effects despite the fact that physicians and their patients are consistently confronted with this balance. Because one of the goals of pharmacogenomics is to identify individuals and target populations that might have adverse outcomes, pharmaceutical companies have been reluctant to use a strategy that might identify patients who are not eligible for a particular treatment. This view is changing because drug-discovery programmes and treatments that target specific pathways, are showing improvements in surrogate and survival endpoints. HIV and cancer are now regarded as chronic diseases, which commonly need life-long systemic treatment from the time of diagnosis. HIV and cancer medicine have used pharmacogenomics to some extent in clinical care. Common and classic features of pharmacogenomics that are related to both antiretroviral treatment and to cytotoxic treatment are discussed in this review, providing a framework for individual treatment of these diseases.
