ABSTRACT

ABSTRACT Introduction: The oral cavity can present the first clinical manifestations of leukemia, therefore; it is important to recognize their principal characteristics. Objective: To identify oral manifestations as the first clinical signs of leukemia. Methods: This is an integrative review, that gathered data from articles with oral manifestations of leukemia as part of its first clinical features. The were included case reports, case series, clinical research, or reviews with case reports. The variables that were considered relevant: age, sex, sites of the oral lesions, characteristics of the oral lesions, medical history and physical examination, time of evolution, radiographic examination, blood test results, initial diagnosis, differential diagnosis and final diagnosis. Results: A total of 31 studies were included, with a total of 33 individuals identified. There were 19 (57.57%) males and 14 (42.42%) females. The age range was from 1.6 to 74 years. Acute myeloid leukemia (72.72%) and acute lymphoid leukemia (18.18%) presented more oral manifestations as the first clinical signs of the disease. All individuals with leukemia presented lesions, such as ulcer, erosion, bleeding, ecchymosis, color change of the bluish or pale mucous membranes and areas of tissue necrosis. Hard tissue lesions were less frequent, being 6 (18.18%). Conclusion: The first clinical manifestations of leukemia can be present in the oral cavity, mainly in acute myeloid leukemia. The principal oral tissues affected were gingival tissue, buccal mucosa and hard and/or soft palate. When hard tissues, such as the maxilla bone or mandible bone were affected, dental mobility was the principal clinical sign.

ABSTRACT

Resumen Los virus de inmunodeficiencia y leucemia felina representan un problema de gran envergadura para los felinos domésticos debido a la multiplicidad de sintomatologías que manifiestan. El objetivo del presente estudio fue establecer, retrospectivamente, la prevalencia en la presentación de ViLeF y VIF en pacientes de seis clínicas de pequeños animales en Bogotá y Chía, en relación con factores como su edad, raza y género. Se realizó un estudio transversal y retrospectivo, mediante la recopilación de datos de 1.014 historias clínicas de pacientes felinos que ingresaron a seis clínicas de la ciudad de Bogotá y Chía, para determinar la prevalencia de VIF y ViLeF y la asociación de estas con factores como edad, género y raza, entre 2015 y 2019, a través de la prueba OR. La detección de los virus se realizó mediante una prueba rápida basada en inmunocromatografía. La mayor prevalencia para cada enfermedad por año fue: 12,3% para VIF en 2012 y 18% para ViLeF en 2019. Los machos presentaron mayores seroprevalencias para ambas enfermedades durante la mayoría los años evaluados. Factores como raza (criolla: VIF: 1,85; ViLeF: 2,01), género (macho: VIF: 1,53 OR; ViLeF: 1,64) y edad (> 7 años: VIF: 3,82; ViLeF: 3,21) se relacionaron positivamente con la presentación de ambas enfermedades en la población felina evaluada.


Abstract Immunodeficiency virus and feline leukemia virus represent major problems for domestic felines due to the multiplicity of symptoms they manifest. The objective of the present study was to establish, retrospectively, the prevalence in the presentation of FeLV and FIV in patients from six small animal clinics in Bogota and Chia, related to factors such as age, race, and gender. A cross-sectional and retrospective study was carried out, collecting data from 1.014 clinical records of feline patients who were admitted to six clinics in the city of Bogota and Chia, to determine the prevalence of FIV and FeLV and their association with factors such as age, gender, and race, between 2015 and 2019 through the OR test. The detection of the viruses was carried out through a rapid test based on immunochromatography. The highest prevalence for each disease per year was 12,3% for FIV in 2012 and 18% for FeLV in 2019. Males presented higher seroprevalences for both diseases during most of the years evaluated. Factors such as race (Creole: FIV: 1,85; FeLV: 2,01), gender (male: FIV: 1.53 OR, FeLV: 1,64), and age (> 7 years: FIV: 3.82; FeLV: 3.21) were positively related to the presentation of both diseases in the feline population evaluated.

ABSTRACT

Abstract Introduction Coronavirus disease 2019 (COVID-19) may present with extrapulmonary manifestations, including hematologic changes. Previous studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) can interact with the renin-angiotensin system, ultimately causing increased production of angiotensin II. By reporting the cases of previously healthy young adults diagnosed with a hematologic malignancy after experiencing COVID-19, we raise the hypothesis that the SARS-Cov-2 infection could act as a trigger for leukemogenesis in predisposed individuals. Methods This was a case series performed through extraction of relevant clinical information from the medical records of three patients admitted to our Hematology unit between August 2020 and September 2020. Main Results Considering the relatively rapid development of cytopenias following recovery from COVID-19, it cannot be ruled out that SARS-Cov-2 played a role in leukemogenesis in those patients. Based on previous in vitro studies, the renin-angiotensin system imbalance induced by SARS-CoV-2 could potentially promote in vivo leukemogenesis through several mechanisms. Conclusion Despite the advances in pathophysiological and clinical characterization of COVID-19, the consequences of the pandemic to the incidence of hematologic diseases are still to be elucidated. In this context, future dissection of the status of the local bone marrow renin-angiotensin system in leukemogenesis is a clinically relevant basic research area.

ABSTRACT

Objective: To construct chimeric antigen receptor (CAR) T cells targeting CD52 (CD52 CAR-T) and validate the effect of CD52 CAR-T cells on CD52-positive leukemia. Methods: A second-generation CD52-targeting CAR bearing 4-1BB costimulatory domain was ligated into a lentiviral vector through molecular cloning. Lentivirus was prepared and packaged by 293 T cells with a four-plasmid system. Fluorescein was used to label cell surface antigens to evaluate the phenotype of CD52 CAR-T cells after infection. Flow cytometry and ELISA were used to evaluate the specific cytotoxicity of CD52 CAR-T cells to CD52-positive cell lines in vitro. Results: ①A pCDH-CD52scFv-CD8α-4-1BB-CD3ζ-GFP expressing plasmid was successfully constructed and used to transduce T cells expressing a novel CD52-targeting CAR. ②On day 6, CD52-positive T cells were almost killed by CD52-targeted CAR-T post lentivirus transduction [CD52 CAR-T (4.48 ± 4.99) %, vs Vector-T (56.58±19.8) %, P=0.011]. ③T cells transduced with the CAR targeting CD52 showed low levels of apoptosis and could be expanded long-term ex vivo. ④The CD52 CAR could promote T cell differentiation into central and effector memory T cells, whereas the proportion of T cells with a CD45RA(+) effector memory phenotype were reduced. ⑤CD52 CAR-T cells could specifically kill CD52-positive HuT78-19t cells but had no killing effect on CD52-negative MOLT4-19t cells. For CD52 CAR-T cells, the percentage of residual of HuT78-19t cells was (2.66±1.60) % at an the E:T ratio of 1∶1 for 24 h, while (56.66±5.74) % of MOLT4-19t cells survived (P<0.001) . ⑥The results of a degranulation experiment confirmed that HuT78-19t cells significantly activated CD52 CAR-T cells but not MOLT4-19t cells[ (57.34±11.25) % vs (13.06± 4.23) %, P<0.001]. ⑦CD52 CAR-T cells released more cytokines when co-cultured with HuT78-19t cells than that of vector-T cells [IFN-γ: (3706±226) pg/ml, P<0.001; TNF-α: (1732±560) pg/ml, P<0.01]. Conclusions: We successfully prepared CD52 CAR-T cells with anti-leukemia effects, which might provide the foundation for further immunotherapy.

ABSTRACT

OBJECTIVE@#To explore the expression levels and clinical significance of helper T cell 1/helper T cell 2 (Th1/Th2) cytokine and interleukin-6 (IL-6) in patients with acute leukemia (AL) complicated by infection.@*METHODS@#68 patients with AL complicated by infection admitted to Wuhan Fifth Hospital from May 2017 to January 2020 were enrolled as study group, 50 AL patients without infection were enrolled as AL group, and 30 healthy volunteers checked in physical examination center were enrolled as healthy control group. The levels of serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10), and peripheral blood Th1/Th2 cells subsets were measured and compared among the three groups. The serum IL-6, IL-10, TNF-α and Th1/Th2 were compared between the patients with mild to moderate infection (n=52) and septic shock (n=16). The relationship between IL-6, IL-10, TNF-α, Th1/Th2 and AL infection was analyzed.@*RESULTS@#The levels of IL-6, IL-10 , TNF-α, and the proportion of Th2 of the patients in study group and AL group were significantly higher than those in healthy control group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in healthy control group (P<0.001). The levels of IL-6, IL-10 and TNF-α, and the proportion of Th2 the patients in study group were significantly higher than those in AL group (P<0.001), while the proportion of Th1 and Th1/Th2 were significantly lower than those in AL group (P<0.001). The serum IL-6, IL-10 and TNF-α level of the patients in septic shock group were significantly higher than those in mild-to-moderate infection group (P<0.001), while Th1/Th2 was lower than those in mild-to-moderate infection group (P<0.001). The results of ROC curve analysis showed that the area under the ROC curve (AUC) values of IL-6, IL-10, TNF-α and Th1/Th2 alone for the diagnosis of septic shock were 0.779, 0.761, 0.724 and 0.718, which were lower than that their combination (0.910) (P<0.05).@*CONCLUSION@#The levels of serum IL-6, IL-10 and TNF-α are high in patients with AL complicated infection and septic shock, while Th1/Th2 cell subsets is low. The combined detection of serum IL-6, IL-10, TNF-α and Th1/Th2 is a good diagnostic value for predicting the occurrence of severe septic shock.

ABSTRACT

OBJECTIVE@#To explore the effect of carvacrol on the biological behavior of leukemia cells and its regulation to circ-0008717/miR-217 molecular axis.@*METHODS@#Human acute lymphoblastic leukemia cells Molt-4 were cultured in vitro, and different concentrations of carvacrol were added to the cells. si-NC and si-circ-0008717 were transfected into Molt-4 cells (si-NC group, si-circ-0008717 group). pcDNA, pcDNA-circ-0008717, anti-miR-NC, anti-miR-217 were transfected into Molt-4 cells and then added to carvacrol-treated cells (carvacrol+pcDNA group, carvacrol+pcDNA-circ-0008717 group, carvacrol+anti-miR-NC group, carvacrol+anti-miR-217 group). MTT, plate clone formation experiment, and flow cytometry were used to detect the viability of the cell, colony formation number, and apoptosis rate of cells, respectively. The RT-qPCR method was used to detect the expression levels of circ-0008717 and miR-217. The dual luciferase reporter gene experiment was used to detect the targeting relationship between circ-0008717 and miR-217.@*RESULTS@#After carvacrol treatment, the cell viability decreased significantly (r=-0.9405), expression level of circ-0008717 decreased (r=-0.9117), colonies formed number decreased (r=-0.9256), while the cell apoptosis rate increased (r= 0.8464), and the expression level of miR-217 increased (r=0.9468). Compared with the si-NC group, the expression level of miR-217 in si-circ-0008717 group increased (P<0.001), the cell apoptosis rate increased (P<0.001), while cell viability decreased (P<0001), the number of colonies formed decreased (P<0.001). Compared with the carvacrol+pcDNA group, the cell viability of the carvacrol+pcDNA-circ-0008717 group increased (P<0.001), the number of colonies formed increased (P<0.001), while the cell apoptosis rate decreased (P<0.001). circ-0008717 could target miR-217. The cell viability of the carvacrol+anti-miR-217 group increased (P<0.001), and the number of colonies formed increased (P<0.001), while the cell apoptosis rate decreased (P<0001) as compared with the carvacrol+anti-miR-NC group.@*CONCLUSION@#Carvacrol can promote the expression of miR-217 by down-regulating the expression of circ-0008717, thereby reducing the proliferation and cloning ability of leukemia cells and promoting cell apoptosis.

ABSTRACT

OBJECTIVE@#To explore the relationship between the level of soluble HLA-E (sHLA-E) molecules in plasma and gene polymorphism and leukemia in Shenzhen of China.@*METHODS@#Enzyme-linked immunosorbent assay was used to detect sHLA-E level in plasma of 103 leukemia patients and 113 healthy blood donors. PCR-SBT was used to identify the HLA-E genotype of 73 leukemia patients and 76 healthy blood donors.@*RESULTS@#The level of plasma sHLA-E of 103 leukemia patients was significantly higher than that of 113 healthy blood donors (P<0.001); And the level of plasma sHLA-E in 77 myeloid leukemia patients was also significantly higher (P<0.001). The percentage of patients with plasma sHLA-E concentration of 0-199 ng/ml in leukemia and myeloid leukemia patients was 37.86% and 32.47%, respectively, which was significantly lower than 53.98% of healthy donors, the difference was statistically significant (P<0.05, P<0.01); While, when the plasma sHLA-E concentration was more than 400 ng/ml, the percentage was 33.01% and 36.36%, respectively, which was significantly higher than 13.28% of healthy donors, the difference was also statistically significant (P=0.001, P<0.001). There was no significant difference in the level of plasma sHLA-E among different HLA-E genotypes (P>0.05), whether healthy blood donors or leukemia patients.@*CONCLUSION@#The level of plasma sHLA-E in patients with leukemia (especially myeloid leukemia) is significantly higher than that of healthy blood donors, but different HLA-E genotypes do not affect the level of plasma sHLA-E. A cut-off value for the concentration of plasma sHLA-E (recommended risk value >400 ng/ml) can be set to assess the risk of certain pre-leukemia patients.

ABSTRACT

OBJECTIVE@#To detect loss of heterozygosity (LOH) at human leukocyte antigen (HLA) loci in a Chinese patient with leukemia after haploidentical hematopoietic stem cell transplantation.@*METHODS@#HLA genotyping was carried out on peripheral blood, hair follicle and buccal swab samples derived from the patient after the transplantation as well as peripheral blood samples from his parents by using PCR-sequence specific oligonucleotide probe method and PCR-sequence based typing method. Short tandem repeat (STR) loci were detected by using a 23 site STR assay kit and a self-developed 6 STR loci assay for the HLA regions.@*RESULTS@#After the transplantation, the HLA genotype of the peripheral blood sample of the patient was identical to his father. The patient was HLA-A*02:01,24:02, C*03:03,03:04, B*13:01,15:01, DRB1*08:03,12:02, DQB1*03:01,06:01 for his hair follicle specimen. However, homozygosity of the HLA loci was found in his buccal swab sample. Only the HLA-A*24:02-C*03:03-B*15:01-DRB1*08:03-DQB1*06:01 haplotype from his father's was present, while the HLA-A*02:01-C*03:04-B*13:01-DRB1*12:02-DQB1*03:01 haplotype from his mother was lost. After the transplantation, the alleles of the 23 STR sites in the patient's peripheral blood sample were consistent to his father, with no allelic loss detected in his buccal swab sample. However, at least 4 STR loci in the HLA region were lost in his buccal swab sample.@*CONCLUSION@#LOH at the HLA loci has been detected in the buccal swab sample of a patient with leukemia who received haploidentical hematopoietic stem cell transplantation.

ABSTRACT

To investigate the toxicity and related mechanism of miltirone to human acute myeloid leukemia THP-1 cells. To be specific, the active components and targets of miltirone were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the target proteins were converted into standard gene names with UniProt. Acute leukemia-rela-ted target genes were screened from GeneCards and DisGeNET. Venn diagram was constructed with Venny 2.1 to yield the common targets of the disease and the drug. The protein-protein interaction(PPI) network was constructed by STRING and Cytoscape 3.8.2. THP-1 cells in the logarithmic growth phase were treated with dimethyl sulfoxide(DMSO), and 2.5, 5, 10, 15, and 20 μmol·L~(-1) miltirone for 24 h, respectively. The proliferation rate of cells was analyzed by carboxyfluorescein diacetate succinimidyl ester(CFSE), apoptosis rate by flow cytometry with Annexin V-PE/7 AAD staining, and cell morphology by acridine orange staining. Real-time quantitative PCR(qPCR) was employed to detect the mRNA levels of nuclear receptor coactivator 2(NCOA2), poly(ADP-ribose) polymerase-1(PARP1), B-cell lymphoma-2(Bcl-2)-associated X protein(Bax), Bcl-2, and cysteine aspartyl protease-3(caspase-3). The effect of miltirone on apoptosis was detected in presence of caspase inhibitor Z-VAD-FMK. A total of 26 targets of miltirone, 1 046 genes related to acute leukemia, and 6 common targets of the two were screened out. Flow cytometry result showed miltirone at 10 μmol·L~(-1) can inhibit proliferation and promote apoptosis of THP-1 cells. The typical manifestations of apoptosis, such as cell shrinkage, nuclear rupture, and chromatin agglomerate were displayed by acridine orange staining. The decreased mRNA levels of NCOA2 and PARP1 and increased Bax/Bcl-2 ratio and the activity of pro-apoptotic protein caspase-3 were observed. Z-VAD-FMK can attenuate the apoptosis-inducing effect of miltirone. This study indicates that miltirone can inhibit the proliferation and promote the apoptosis of THP-1 cells, by down-regulating NCOA2 and PARP1, raising Bax/Bcl-2 ratio, and activating caspase-3.

ABSTRACT

RESUMO Objetivo Identificar a ocorrência de disfunções orofaciais em pacientes infantojuvenis com leucemia aguda, submetidos à quimioterapia de remissão. Métodos Em um período de 16 meses, 40 pacientes com leucemias agudas, entre 3 e 18 anos de idade, foram admitidos em um hemocentro no estado do Amazonas. Destes, 23 foram incluídos neste estudo transversal e submetidos à avaliação das funções orofaciais, por meio do Nordic Orofacial Test-Screening (NOT-S), entre o trigésimo (D30) e o trigésimo terceiro dia (D33) da fase de indução da remissão. A presença de manifestações orais também foi avaliada por meio de exame clínico. Resultados Disfunção orofacial foi observada em, aproximadamente, metade dos casos avaliados (n=11). Destes pacientes, todos tiveram o domínio Secura de Boca (VI) alterado e 81,8% (n=9) apresentaram alteração no domínio Mastigação e Deglutição (IV). Mucosites em lábios, língua, soalho e orofaringe foram as lesões orais mais encontradas após a fase de indução. Houve associação entre a ocorrência de lesões orais nos pacientes avaliados e a presença de disfunção orofacial, segundo o NOT-S (IC 95%, p-valor = 0,027). Conclusão Sugere-se que a disfunção orofacial seja frequente na fase de indução da remissão em pacientes infantojuvenis com leucemias agudas. Estudos sobre as disfunções orofaciais nessa população, bem como sua relação com as lesões orais são necessários para melhor esclarecimento e compreensão dos impactos funcionais.


ABSTRACT Purpose To Identify the occurrence of orofacial dysfunctions in young children and adolescents with acute leukemia who are undergoing remission chemotherapy. Methods Over a period of 16 months, 40 three to eighteen year -old patients with acute leukemia were admitted to the Amazonas State Hemocenter. Of these, 23 were included in the cross-sectional study and submitted to the evaluation of orofacial functions using the Nordic Orofacial Test-Screening, between D30 and D33 of the remission induction phase. The presence of oral manifestations was also evaluated via clinical examination. Results Orofacial dysfunction was observed in approximately half of the evaluated cases (n=11). Of these patients, all had alterations in the Dryness of the Mouth (VI) domain and 81.8% (n=9) showed alterations in the Chewing and Swallowing (IV) domain. Mucosites on lips, tongue, floor of the mouth and the oropharynx were the most commonly found oral lesions after the remission induction phase. According to the NOT-S, there was an association between the occurrence of oral lesions in the evaluated patients and the presence of orofacial dysfunction (95% CI, p-value = 0.027). Conclusion It is suggested that orofacial dysfunction is frequent in the remission induction phase in children and adolescents with acute leukemia. Studies regarding these orofacial dysfunctions in this population, as well as their relationship with oral lesions, are needed in order to fully understand their functional impact.

ABSTRACT

Trata-se de um estudo do tipo caso-controle pareado com o objetivo de verificar a associação entre ocupações e cânceres linfohematopoiéticos em um hospital público de referência no Estado do Ceará, Brasil, durante 2019-2021. O grupo caso foi constituído por pacientes hematológicos que apresentavam mieloma múltiplo, leucemias ou linfomas não Hodgkin, acompanhados pelo serviço social de uma unidade hospitalar de transplante de medula óssea (n = 114), enquanto indivíduos comparáveis de unidade hospitalar distinta constituíram o grupo controle (n = 114), formando pares 1:1. O diagnóstico foi efetuado por equipe médica e as variáveis foram aferidas por acesso aos registros hospitalares. Comparamos os grupos em regressão logística condicional bivariada e ajustada por região de residência. Entre os resultados, destacamos que o câncer de maior prevalência no grupo caso foi o mieloma múltiplo (43,9%), seguido pelas leucemias (43%) e por linfomas não Hodgkin (13,2%). Proporções de ocupações, zona de residência, abastecimento de água e Superintendência Regional de Saúde de residência apresentaram diferença estatisticamente significante entre os grupos caso e controle. Verificamos que trabalhadores rurais possuíam maiores chances de apresentar os cânceres estudados (ORbruto = 5,00, IC95%: 1,91; 13,06 e ORajustado = 3,38, IC95%: 1,20; 9,54), enquanto trabalhadores do comércio apresentaram menores chances (ORbruto = 0,26, IC95%: 0,10; 0,70 e ORajustado = 0,30, IC95%: 0,10; 0,88). Os achados deste estudo possibilitam reflexões sobre o processo de adoecimento dos trabalhadores rurais e refletem o potencial dos serviços de saúde em contribuir com investigações sobre exposições ocupacionais.


This is a paired case-control study that sought to verify the association between professions and lymphohematopoietic cancers in a public reference hospital in the State of Ceará, Brazil, during 2019-2021. Case group consisted of hematological patients with multiple myeloma, leukemias or non-Hodgkin lymphomas, monitored by the social service of a bone marrow transplant hospital unit (n = 114), whereas comparable individuals from a different hospital unit made up the control group (n = 114), forming 1:1 pairs. Diagnosis was performed by a medical team and the variables were measured by accessing hospital records. Group comparison was conducted using bivariate conditional logistic regression and adjusted by region of residence. Results show that multiple myeloma (43.9%), leukemias (43%) and non-Hodgkin lymphomas (13.2%) were the cancer with the highest prevalence in the case group. Proportions of jobs, area of residence, water supply and Regional Superintendence of Health showed statistically significant difference between the case and control groups. Rural workers were more likely to present the cancers studied (ORraw = 5.00, 95%CI: 1.91; 13.06 and ORadjusted = 3.38, 95%CI: 1.20; 9.54), whereas trade workers had lower odds (ORraw = 0.26, 95%CI: 0.10; 0.70 and ORadjusted = 0.30, 95%CI: 0.10; 0.88). The findings allow us to reflect on the process of illness among rural workers and illustrate the potential of health services to contribute to investigations on occupational exposures.

ABSTRACT

Introducción: el benceno es un hidrocarburo aromático obtenido por destilación del alquitrán utilizado en gasolineras y como solvente industrial, clasificado como cancerígeno por exposición ocupacional o ambiental. Está relacionado con el desarrollo de leucemia mieloide aguda (LMA) por su absorción principal por vía inhalatoria, y su metabolismo hepático con producción de benzoquinona de alta liposolubilidad que le permite depositarse en la médula ósea y tejido graso. Objetivo: analizar la asociación de las formas de exposición por actividades económicas, oficios, cargos, exposición ambiental y aditiva con el desarrollo de LMA. Materiales y métodos: revisión sistemática de la literatura en las bases de datos Medline, Embase, Lilacs, Cochrane Library, Toxnet y OpenGrey, en inglés y español con los términos benzene, cancer, leukemia, occupational and enviromental exposition. Resultados: la mayoría de los estudios muestran una relación causal entre la exposición a benceno y el desarrollo de LMA, con predominio en ambientes laborales, seguidos de factores ambientales y aditivos como el humo del cigarrillo. Conclusiones: se encontró evidencia de asociación entre la exposición a benceno ocupacional y/o ambiental con el desarrollo de leucemia mieloide aguda, debido a que altera el estrés oxidativo y la desregulación del aryl hidrocarburo generando efectos citogenéticos, mutación genética y alteraciones epigenéticas que se expresan en hematotoxicidad y desarrollo de leucemia.


Introduction: Benzene is an aromatic hydrocarbon obtained by distillation of tar used in gas stations and as an industrial solvent, classified as a carcinogen by occupational and environmental exposure. It is related with the development of acute myeloid leukemia (AML) mainly due to its absorption by inhalation and hepatic metabolism producing highly-lipid soluble benzoquinone allowing it to deposit in bone marrow and fatty tissue. Objective: to analyze the association of forms of exposure including economic activities, type of workplace, environmental and additive exposure with the development of AML. Material and Methods: systematic review of the literature in Medline, Embase, Lilacs, Cochrane Library, Toxnet and OpenGrey databases in English and Spanish, using the terms benzene, cancer, leukemia, occupational and environmental exposure. Results: most studies show a causal relationship between benzene exposure and AML development, predominantly in work settings, followed by environmental factors including additive sources such as cigarette smoke. Conclusions: we found evidence of an association between occupational and/or environmental exposure to benzene and the development of AML, for it alters oxidative stress and aryl hydrocarbon deregulation inducing cytogenetic aberrations, genetic mutations and epigenetic changes expressed as hematotoxicity and leukemia development.

ABSTRACT

Resumen Una de las herramientas más novedosas en inmunoterapias adoptivas contra leucemias y tumores malignos es el uso del receptor de antígeno quimérico "CAR". El receptor CAR ha sido ampliamente utilizada en células T (células CAR-T) potenciando su eficacia en el reconocimiento y eliminación de tumores, obteniéndose a la fecha terapias basadas en esta tecnología. No obstante, las células CAR-T llegan a repercutir negativamente en la salud del paciente, presentando el síndrome neurológico de efecto inmune asociado a células (ICANS) y el síndrome de lanzamiento de citocinas (SLC). Como consecuencia, el paciente necesita ser hospitalizado durante la terapia. Además, el coste de manufactura y terapia es elevado, siendo una tecnología limitada a un sector muy bajo de la población. En este trabajo, mencionamos el empleo de una terapia emergente de células asesinas naturales (NK) con el receptor CAR (CAR-NK), que cuentan con muchas ventajas por encima de las células CAR-T. Las células CAR-NK conservan su capacidad citotóxica en contra de tumores gracias a su acción dependiente de receptores activadores e inhibidores, por lo que el receptor CAR, solo estimula sus habilidades y persistencia. Sumado a esto, el coste de una terapia de células CAR-NK podría resultar redituable debido a la capacidad de las células CAR-NK de eliminar múltiples células tumorales sin generar daño colateral en el paciente. Aquí analizamos las características de los múltiples receptores CAR y los fenotipos de células NK que han sido utilizados durante múltiples ensayos (NK-92, células NK de sangre cordal y periférica, y células NK iPSC).


Abstract One of the novel and effective devices against leukemia and solid tumors in adoptive immunotherapies is the use of the chimeric antigen receptor "CAR". CAR technology has been widely used in T-cells (CAR-T cells) empowering its efficacy on the identification and elimination of tumor cells, getting today certain drugs based on this technology. Nevertheless, CAR-T cells can have a negative impact on patient health, causing in many cases immune effector cell-associated neurotoxicity syndrome (ICANS) and cytokine release syndrome (CRS). As a consequence, the patient will have to be hospitalized for the duration of therapy. Moreover, the cost of manufacture and therapy is quite expensive, limiting its use to a low range of people. On the other hand, we analyze the advantages of Natural Killer cells with the CAR receptor (CAR-NK), which have many plusses over CAR-T cells. CAR-NK cells retain their cytotoxic abilities against tumor cells due their activator/ inhibitor receptors balance. Thus, the CAR receptor technology just increases their skills and persistence. Furthermore, CAR-NK therapy could be more profitable since CAR-NK can eliminate multiple tumor cells without generating collateral damage on patient health. Here, we discuss the characteristics of the multiples CAR receptors in general and the NK types cells that have been used in trials demonstrating their viable emerging therapy (NK-92, cord and peripheral blood NK cells, and iPSC-derived NK cells).
