Estado nutricional, força muscular e capacidade funcional em portadores de mieloma múltiplo / Nutritional status, muscle strength and functional capacity in patients with multiple myeloma

O mieloma múltiplo é uma neoplasia maligna caracterizada pela proliferação clonal de plasmócitos na medula óssea. O objetivo deste trabalho foi avaliar as possíveis associações entre o estado nutricional, força muscular e capacidade funcional de pacientes ambulatoriais portadores de mieloma múltiplo. Trata-se de estudo transversal realizado em amostra não probabilística de pacientes com mieloma múltiplo atendidos no Hospital das Clínicas, em Goiânia. Os dados foram coletados entre agosto e dezembro de 2015, utilizando-se de entrevistas e informações dos prontuários. O estado nutricional foi avaliado aplicando-se a Avaliação Subjetiva Global Produzida pelo Próprio Paciente; a força muscular medida por meio da Força do Aperto de Mão e a capacidade funcional, pela Escala de Performance de Karnofsky. O estudo foi aprovado pelo Comitê de Ética e Pesquisa do referido hospital. Foram avaliados 52 pacientes, em que 48,1% estavam desnutridos, 30,8% apresentavam baixa força muscular e 73,1%, comprometimento da capacidade funcional. A força muscular e a capacidade funcional foram menores nos desnutridos. Observou-se que aqueles que utilizavam corticoides apresentaram 18% menos chance de se tornarem desnutridos (OR=0,18; IC=0,05-0,62; p=0,011) porém, é importante considerar as possíveis causas de viés; por outro lado, os pacientes com baixa força muscular ou faziam quimioterapia apresentaram, aproximadamente, quatro vezes mais chances de desnutrição, respectivamente (OR=3,46; IC=0,99-12,08; p=0,047) (OR=3,64; IC=1,13-11,69; p=0,027). Concluiu-se que a desnutrição é comum nos pacientes portadores de mieloma múltiplo, indicando a necessidade premente de intervenção nutricional apropriada e precoce.

Multiple myeloma is a malignant neoplasm characterized by the clonal proliferation of plasma cells in the bone marrow. The objective of this study was to evaluate possible associations between nutritional status, muscle strength and functional capacity of outpatients with multiple myeloma. This is a cross-sectional study carried out on a non-probabilistic sample of patients with multiple myeloma treated at Hospital das Clínicas, in Goiânia. Data were collected between August and December 2015, using interviews and information from medical records. Nutritional status was assessed using the Patient Generated Subjective Global Assessment; muscular strength measured using Hand Grip Strength and functional capacity, using the Karnofsky Performance Scale. The study was approved by the Ethics and Research Committee of that hospital. 52 patients were evaluated, of which 48.1% were malnourished, 30.8% had low muscle strength and 73.1% had impaired functional capacity. Muscle strength and functional capacity were lower in malnourished individuals. It was observed that those who used corticosteroids were 18% less likely to become malnourished (OR=0.18; CI=0.05-0.62; p=0.011), however, it is important to consider the possible causes of bias; on the other hand, patients with low muscle strength or undergoing chemotherapy were approximately four times more likely to be malnourished, respectively (OR=3.46; CI=0.99-12.08; p=0.047) (OR=3.64; CI=1.13-11.69; p=0.027). It was concluded that malnutrition is common in patients with multiple myeloma, indicating the pressing need for appropriate and early nutritional intervention.

Six-year experience with GM test in hematological patients in a public Brazilian tertiary hospital

Abstract Invasive fungal infection (IFI) is frequent in patients with hematologic malignancies or submitted hematopoietic stem cell transplantation (HSCT). Objectives To evaluate the role of the GM (galactomannan) test in prescribing therapeutic antifungals; to determine invasive aspergillosis (IA) frequency, the factors associated with positive GM test, and the in-hospital mortality. Methods We conducted a retrospective observational study including patients aged 18 or over with hematological malignancy or submitted to HSCT. GM test was measured twice weekly. The hypothesis of IFI was considered in patients with neutropenia and persistent fever despite broad-spectrum antibiotics. Results A total of 496 patients were evaluated; the mean of GM tests performed per patient was 4.2 (+3.1), and 86 (17.3 %) had positive results. IFI was diagnosed in 166 (33.5 %) and IA in 22 (24.6 %) patients. Positive GM test was more frequent in patients with IFI (72.2 % and 25.1 %; OR 8.1; 95 % CI 4.8 - 13.8), and was associated with therapeutic antifungals prescription (52, 9 % and 20.5 %; OR 4.3, 95CI% 2.0 - 9.4), as well as lung abnormalities on HRCT (45.3% vs. 21.5 %; OR 3.0, 95 %CI 1.4 - 6.5). Mortality was 31.6 %. In the multivariate analysis, the variables associated with mortality were the hypothesis of IFI (OR 6.35; 95 % CI 3.63-11.12.0), lung abnormalities on HRCT (57.9 % and 26.9 %; OR 2 0.6; 95 % CI 1.5 - 4.4), and positive GM test (57.9 % and 26.9 %; OR 2.7 95 % CI 1.6 - 4.5). Conclusions Positive GM test was associated with lung abnormalities on HRCT and with the introduction of therapeutic antifungals. If adequate anti-mold prophylaxis is available, the GM test should not be used as screening, but to investigate IFI in high-risk patients. The diagnosis of IFI, positive GM test and lung abnormalities on HRCT were predictors of hospital mortality in patients with hematological malignancies or undergoing HSCT.

Risk prediction model of survival after hematopoietic stem cell transplantation in patients with malignant hematological diseases / 公共卫生与预防医学

Objective To analyze the risk factors for survival in patients with hematological malignancies after hematopoietic stem cell transplantation (HSCT), to establish a risk prediction and survival prediction model, and to provide a reference for clinical diagnosis and treatment. Methods A total of 237 patients with malignant hematological diseases who underwent HSCT at West China Hospital of Sichuan University from January 2017 to April 2019 were selected as the study subjects. The survival of all patients after HSCT was statistically analyzed. The influencing factors of survival were analyzed by multivariate regression analysis, and the prediction model was constructed. Results A total of 237 patients with hematological malignancies were included in this study. After 3 years of follow-up, 85 patients died, with a mortality rate of 35.86%. Multivariate logistic analysis showed that diabetes mellitus (OR=4.358, P=0.007), infection (OR=3.522, P=0.000), neutropenia time >7d (OR=2.734, P=0.009), incomplete HLA matching (OR=5.688, P=0.000), cGVHD (OR=2.593, P=0.007) and HCT-CI (OR=6.701, P=0.000) were independent risk factors affecting the survival of patients with hematological malignancies after HSCT (P(3.192 + 01.259 + 1.472 ×(diabetes mellitus) + 1.259×(infection) + 1.006 ×(neutropenia time) + 1.738 ×(HLA matching) + 0.953 ×(cGVHD) + 1.902 ×(HCT-CI)), Hosmer-Lemeshow χ2=6.692, P=0.462. AUC and 95%CI of the model for predicting survival were 0.836 and 0.783-0.888, showing good fit and predictive efficiency. Conclusion Diabetes mellitus, infection, neutropenia time >7d, incomplete HLA matching, cGVHD and HCT-CI are all high-risk factors of survival in patients with malignant hematologic disease after HSCT. Clinically, attentions should be paid to these patients and intervention measures should be taken to improve their survival after HSCT.

Seroprevalence of the specific antibody against Toxoplasma gondii among patients with hematological diseases / 中国血吸虫病防治杂志

Objective To investigate the seroprevalence of Toxoplasma gondii infections among patients with hematological diseases, so as to provide insights into improving the prognosis and quality of life among patients with hematological diseases. Methods A total of 240 patients with hematological diseases (including 170 patients with hematological tumors and 70 patients with non-tumor hematological diseases) admitted to The Affiliated Hospital of Putian University during the period from January 1, 2021 through October 10, 2023 and 500 healthy volunteers in the hospital during the same period were enrolled. Subjects’ demographics and serum samples were collected, and serum specific IgG and IgM antibodies against T. gondii were detected using the chemiluminescence assay, with any of a positive IgG or IgM antibody defined as a positive T. gondii infection. The seroprevalence of specific IgG and IgM antibodies against T. gondii was compared between patients with hematological diseases and healthy volunteers. Results The mean age (F = 2.034, P > 0.05) and gender distribution (χ2 = 0.462, P > 0.05) were comparable among patients with hematological tumors, patients with non-tumor hematological diseases and healthy volunteers, and there was no significant difference in the proportion of history of cat or dog contacts between patients with hematological diseases and healthy volunteers (χ2 = 0, P > 0.05). The seroprevalence of anti-T. gondii antibody was significantly higher among patients with hematological diseases than among healthy volunteers (15.8% vs. 0.6%; χ2 = 71.902, P < 0.01), and there was a significant difference in the seroprevalence of anti-T. gondii antibody among patients with hematological tumors (18.2%), patients with non-tumor hematological diseases (10.0%) and healthy volunteers (χ2 = 78.327, P < 0.01). The seroprevalence of anti-T. gondii antibody was significantly higher among patients with hematological tumors and non-tumor hematological diseases than among healthy volunteers (both P values < 0.05), while no significant difference was seen in the seroprevalence of anti-T. gondii antibody between patients with hematological tumors and non-tumor hematological diseases (P > 0.05). In addition, the proportion of history of cat or dog contacts was significantly higher among patients with hematological diseases that were positive for serum anti-T. gondii anti-body than among those negative for serum anti-T. gondii antibody (21.1% vs. 5.4%; χ2 = 8.653, P < 0.05). Conclusions There is a high seroprevalene rate of T. gondii infections among hematological diseases, which is significantly greater than that among healthy volunteers.

Hematological Indicators of Glucose-6-Phosphate Dehydrogenase (G6PD) Deficiency in Malaria-Infected Individuals

@#Introduction: Malaria, a life-threatening infectious disease caused by Plasmodium parasites, continues to be a major global health concern, particularly in regions with high transmission rates. This retrospective cohort study aimed to investigate the hematological indicators of G6PD deficiency in individuals infected with malaria. The study utilized medical records and laboratory test results to analyze the hematological parameters and markers in individuals with confirmed malaria and G6PD deficiency. Methods: Data were collected from the laboratory unit of Mosul Teaching Hospitals in Ninevah Province, Iraq, from March 2021 to November 2022. The study population consisted of individuals diagnosed with malaria and with available G6PD deficiency test results. G6PD deficiency was determined by measuring the G6PD enzyme activity in the patient’s blood. Hematological parameters, including complete blood counts, platelet counts, and red blood cell indices, were recorded using a laboratory information system. Results: The study population exhibited a relatively low prevalence of G6PD deficiency, with no significant differences observed in age or gender distribution between individuals with and without G6PD deficiency. The distribution of malaria types did not differ significantly between the two groups. However, patients with G6PD deficiency showed a significantly higher monocyte count, indicating a potential association between G6PD deficiency and altered monocyte response during malaria infection. The clinical significance of this finding requires further investigation. Conclusion: This study sheds light on the hematological indicators of G6PD deficiency in individuals infected with malaria. The findings suggest a potential relationship between G6PD deficiency and altered monocyte response during malaria infection.

Research Progress of Endoplasmic Reticulum Stress PERK-eIF2α-AFT4-CHOP Signaling Pathway in Hematological Malignancies / 肿瘤防治研究

The biosynthesis and maturation of proteins are primarily regulated by the endoplasmic reticulum in its physiological state. Thus, the disruption of physiological homeostasis initiates the buildup of unfolded and misfolded proteins in the endoplasmic reticulum, resulting in endoplasmic reticulum stress (ERS) and unfolded protein response (UPR). One of the important pathways by which UPR maintains intracellular homeostasis under ERS is activating protein kinase R-like endoplasmic reticulum kinase (PERK). The activation of the PERK pathway stimulates eukaryotic translation initiation factor 2 subunit-α (eIF2α) phosphorylation and the selective translation of active transcription factor 4 (ATF4), and PERK induces cell apoptosis by directly binding to the promoter of pro-apoptotic transcription factor C/EBP homologous protein (CHOP). This signaling pathway is also one of the important mechanisms by which UPR participates in the regulation of hematological malignancies and immune cells in a tumor microenvironment. This article provides an overview of advancements in research into the PERK-eIF2α-ATF4-CHOP signaling pathway in hematological malignancies and the potential therapeutic benefits of targeting this signaling pathway.

Etiología, clínica y evolución de infecciones fúngicas invasoras en pacientes con neoplasias hematológicas en un hospital universitario de Argentina

Introducción: Las infecciones fúngicas invasoras (IFI) en pacientes con neoplasias hematológicas (NH) representan un desafío diagnóstico y terapéutico. Objetivos: Describir la etiología, características clínicas, diagnóstico y evolución de los episodios de IFI probadas y probables en pacientes con NH y trasplante de progenitores hematopoyéticos (TPH). Pacientes y Métodos: Estudio descriptivo, retrospectivo y de cohorte que incluyó IFI probadas y probables en pacientes adultos con NH y TPH. Se realizó seguimiento hasta el día 90. Resultados: Se incluyeron 80 episodios de IFI: 49% probadas y 51% probables, 67,5% por hongos filamentosos (HF), 30% por hongos levaduriformes (HL) y 2,5% por hongos dimorfos. Los tipos de IFI más frecuentes fueron aspergilosis invasoras pulmonares (AP) y candidiasis invasoras (CI), en su mayoría por Candida spp. no albicans. Todos los casos de AP se diagnosticaron por detección de galactomanano en sangre y/o lavado broncoalveolar, y solamente 22,2% presentaban nódulos con halo en la tomografía computada (TC) de tórax, siendo los infiltrados inespecíficos los hallazgos más frecuentes. Tuvieron coinfección bacteriana y viral el 30 y 17,5%, respectivamente. El 50% fueron IFI de brecha, y la mortalidad global y mortalidad relacionada a la IFI fue 51 y 24%, respectivamente. Conclusión: Los HF fueron la principal causa de IFI, con una gran proporción de IFI de brecha, y presentaron elevada mortalidad. Para el diagnóstico, resulta importante la utilización de biomarcadores y jerarquizar cualquier imagen patológica en la TC.

Background: Invasive fungal infections (IFI) in patients with hematological malignancies (HM) represent a diagnostic and therapeutic challenge. Aim: To describe the etiology, clinical characteristics, diagnosis and evolution of proven and probable IFI episodes in patients with HM and hematopoietic stem cell transplantation (HSCT). Methods: Retrospective, descriptive, cohort study performed in adult patients with HM and HSCT, who developed proven and probable IFI. Follow-up was carried out until day 90. Results: A total of 80 IFI episodes were included: 49% proven and 51% probable, 67,5% due to mold (M), 30% to yeast-like fungi (Y) and 2,5% to dimorphic fungi. The most frequent causes were probable pulmonary aspergillosis (PA) and invasive candidiasis (IC), mainly due to non-albicans Candida species. PA were all diagnosed by detection of galactomannan (GM) in blood and bronchoalveolar lavage, and only 22,2% presented halo sign on chest CT. Bacterial and viral coinfections were reported in 30% and 17,5% respectively. Breakthrough IFI occurred in 50%, and global and IFI-related mortality were 51% and 24% respectively. Conclusion: Mold was the main cause of IFI, with a large proportion of breakthrough IFI, presenting high mortality. The use of biomarkers and the classification of any pathological image on CT contribute to the diagnosis.

Perfil de parámetros hematológicos en el HIV pediátrico y los cambios asociados al tratamiento antirretroviral / Hematological parameters profile in pediatric HIV and changes associated with antiretroviral treatment / Perfil de parâmetros hematológicos no HIV pediátrico e as alterações associadas ao tratamento anti-retroviral

Resumen Las alteraciones hematológicas son comunes durante la infección por el virus de la inmunodeficiencia humana (HIV). El objetivo de este trabajo fue describir los perfiles hematológicos e inmunológicos de niños infectados, antes y después de 36 meses de implementado el tratamiento antirretroviral (TARV). Se revisaron historias clínicas de niños expuestos, atendidos en este hospital en el período 2008-2018, con edades entre 6 meses y 14 años. Fueron empleados un contador hematológico (ADVIA 2120), un citómetro de flujo (FACScalibur BD) y una PCR en tiempo real Nuclisens EasyQ (bioMérieux). En 486 historias clínicas se encontraron 58 pacientes sin TARV, 30 por diagnóstico reciente y 28 por adherencia incorrecta o abandono de tratamiento. En ambos grupos se observó disminución porcentual de hemoglobina (Hb) (53% y 43%), volumen corpuscular medio (VCM) (43% y 7%) y LTCD4+ (37% y 57%), respectivamente, sin alteraciones significativas en otros parámetros hematológicos. Veintidós niños con correcta adherencia al TARV incrementaron significativamente los niveles de LTCD4+ (t0:18,8±9%, t1:32,7±6%), Hb (t0:10,9±1,6 g/dL, t1:12,6±1,1g/dL) y VCM (t0:78,7±4,5 fL, t1:101,9±5,6 fL), con disminución simultánea de la carga viral (CV) (t0:4,4±0,75 log t1:<1,70 log) después del seguimiento. La disminución de Hb observada aproximadamente en el 50% de los pacientes sin TARV estaría asociada a la acción viral y al tiempo de evolución de la infección. El incremento en los niveles, asociados a macrocitosis, se relacionaría con el aumento de LTCD4+ y disminución de la CV.

Abstract Hematologic abnormalities are common during human immunodeficiency virus (HIV) infection. Our aim was to describe hematological and immunological profiles present in antiretroviral treatment (ART)-naïve infected children and the changes observed after 36 months of ART initiation. Medical records of exposed children attended at this hospital in the 2008-2018 period were reviewed. Children between 6 months and 14 years were included. An automated blood analyser ADVIA 2120, a FACScalibur BD flow cytometer, and a Nuclisens EasyQ bioMérieux real-time PCR were used to determine different parameters. In 486 medical records evaluated, 58 patients ART-naïve were found, 30 due to recent diagnosis and 28 for incorrect adherence or abandoned treatment. In both groups, a percentage decrease in hemoglobin (Hb) (53% and 43%), mean corpuscular volume (MCV) (43% and 7%) and LTCD4+ (37% and 57%) levels respectively, was observed, without significant alterations in other hematological parameters. Twenty-two children with ART correct adherence increased significantly CD4+T cells (t0:18.8±9%, t1:32.7±6%), Hb (t0:10.9±1.6 g/dL, t1:12.6±1.1 g/dL) and MCV (t0:78.7±4.5 fL, t1:101.9±5.6 fL) levels, with simultaneous decrease of viral load (VL), (t0:4.4±0.75 log, t1:<1.70 log), after 36 months of follow-up. The reduction in Hb levels observed in 50% approximately of patients without ART would be associated with viral action and time of evolution of the infection. The increase in Hb levels and an associated macrocytosis would be related to the CD4+ T cells increase and VL decrease.

Um contador hematológico (ADVIA 2120), um citômetro de fluxo (FACScalibur BD) e um PCR em tempo real Nuclisens EasyQ (bioMérieux), foram usados. Em 486 prontuários foram encontrados 58 pacientes livres de TARV, 30 por diagnóstico recente e 28 por adesão incorreta ou abandono do tratamento. Em ambos os grupos, observou-se diminuição percentual de hemoglobina (Hb) (53% e 43%), volume corpuscular médio (VCM) (43% e 7%) e LTCD4+ (37% e 57%), respectivamente, sem alterações significativas nos demais parâmetros hematológicos. Vinte e duas crianças com adesão correta ao TARV aumentaram significativamente os níveis de LTCD4+ (t0:18,8±9%, t1:32,7±6%), Hb (t0:10,9±1,6 g/dL, t1:12,6±1,1 g/dL) e VCM (t0:78,7±4,5 fL, t1:101,9±5,6 fL), com diminuição simultânea da carga viral (CV) (t0:4,4±0,75 log, t1:<1,70 log), depois do seguimento. A diminuição dos níveis de Hb observada em aproximadamente 50% dos pacientes sem TARV estaria associada à ação viral e ao tempo de evolução da infecção. O aumento nos níveis, associados a macrocitose, estaria relacionado com o aumento de LTCD4+ e diminuição da CV.

Iron profile of pregnant sickle cell anemia patients in Odisha, India

ABSTRACT Introduction: During pregnancy, the iron requirement increases to meet the optimal growth of the fetus and prevent iron deficiency anemia-related complications in the mother. However, in sickle cell disease (SCD) primarily due to repeated blood transfusions and hemolysis-induced recycling of iron, its supplementation during pregnancy remains questionable and may be harmful. Methods: Twenty-five pregnant women with homozygous SCD and 25 pregnant women with normal hemoglobin variants were included as cases and control, respectively. Pregnancy and sickle cell anemia (SCA) were diagnosed using standard protocols. The serum iron, serum ferritin, total iron-binding capacity (TIBC), percentage transferrin saturation and C-reactive protein were estimated, as per the manufacturer's protocol. The complete blood count was performed. The unpaired 't-test' was performed using the SPSS v23.0 and the principal component analysis (PCA) was performed using the online software MetaboAnalyst for statistical analysis. Main Results: The studied cases had significantly lower mean hemoglobin and higher mean corpuscular volume (MCV), compared to controls. The mean serum-iron, serum-ferritin and percentage transferrin-saturation in the cases were significantly higher than that of the controls, while the TIBC was lower in the cases (p < 0.0001). The mean level of serum iron, ferritin, percentage transferrin saturation and TIBC were 309.44 ± 122.40mcg/dl, 860.36 ± 624.64ng/ml, 42.6 ± 17.30% and 241.32 ± 96.30 mcg/dl, respectively, in the cases and 95.36 ± 41.90mcg/dl, 122.28 ± 49.70ng/ml, 15.83 ± 3.10% and 492.6 ± 149.40mcg/dl in the controls, respectively. Higher MCV, mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) with lower hemoglobin (Hb) were noted in the cases. The PCA revealed that the cases were more heterogeneous in terms of the variability of the iron status and hematological indices than the controls. Conclusion: The current study shows iron sufficiency in most cases of pregnancy with SCA and suggests that evaluation of iron status must be made before initiating iron prophylaxis in pregnant women with SCA, especially in regions having a high prevalence of sickle cell hemoglobinopathy.

Asociación entre parámetros hematológicos y fenotipos metabólicamente poco saludables en niños y adolescentes

Introducción: El síndrome metabólico se ha asociado con cambios en parámetros hematológicos (glóbulos rojos, plaquetas y leucocitos); se pueden utilizar para identificar sujetos en riesgo de fenotipos metabólicamente no saludables (MUP). Se investigó si estos parámetros hematológicos sirven como biomarcadores para distinguir el fenotipo metabólicamente sano (MHP) del MUP en niños y adolescentes. Métodos: Estudio transversal, 292 niños y adolescentes. El diagnóstico de MUP fue según consenso. Se utilizó ANOVA unidireccional en las comparaciones, regresión logística múltiple para determinar si el sexo, el grupo etario, el estado nutricional, la pubertad, los parámetros hematológicos y la resistencia a la insulina se asociaron con MUP. Resultados: Edad media 11 años (DE: 2,61). Los valores de RDW fueron significativamente más bajos en los niños en el grupo de peso normal metabólicamente insalubre (MUNW) en comparación con los niños con obesidad metabólicamente no saludable (MUO) (12,33 ± 0,90 vs. 13,67 ± 0,52; p = 0,01) y en la obesidad metabólicamente saludable (MHO) en comparación con el grupo MUO (13,15 ± 0,53 vs. 13,67 ± 0,52; p = 0,04). En adolescentes, la relación plaquetas/linfocitos fue mayor en el grupo MHNW (con un valor medio de 152,60 (DE 62,97) vs 111,16 (DE 44,12) para el grupo MHO. Al ajustar por edad, estado nutricional y pubertad, los índices hematológicos no se asociaron con MUP. Conclusión: Los parámetros hematológicos no están asociados independientemente con el MUP, y es poco probable que representen biomarcadores confiables para la detección del MUP en la población pediátrica.

Introduction: Metabolic syndrome has been associated with changes in several hematological parameters, such as red blood cells, platelets, and leucocytes. Therefore, hematologic parameters can be used to identify the subjects at risk of metabolically unhealthy phenotypes (MUP). The current study investigated if hematological parameters can serve as biomarkers to distinguish metabolically healthy phenotype (MHP) from MUP in children and adolescents. Methods: Two hundred ninety-two children and adolescents were enrolled in this cross-sectional study. The MUP was diagnosed using consensus-based criteria. Group comparisons were performed using one-way ANOVA. Multiple logistic regression analysis was used to determine if sex, age group, nutritional status, puberty, hematological parameters, and insulin resistance were associated with MUP. Results: The subject's age mean was 11 years (SD: 2.61). RDW values were significantly lower in children in the metabolically unhealthy normal weight (MUNW) group compared to children with metabolically unhealthy obesity (MUO) group (12.33 ± 0.90 vs. 13.67 ± 0.52; p = 0.01) and in metabolically healthy obesity (MHO) compared to MUO group (13.15 ± 0.53 vs. 13.67 ± 0.52; p = 0.04). In adolescents, the platelet-to-lymphocyte ratio was higher in the MHNW group, with a mean value of 152.60 (SD 62.97) compared to 111.16 (SD 44.12) for the MHO group. However, after adjusting for age, nutritional status, and puberty, hematological indices were not associated with MUP. Conclusions: The study demonstrates that hematologic parameters are not independently associated with the MUP, and it is unlikely that they represent reliable biomarkers for screening for the MUP in the pediatric population.

One-year mortality of hematopoietic stem cell recipients admitted to an intensive care unit in a dedicated Brazilian cancer center: a retrospective cohort study

ABSTRACT BACKGROUND: Hematopoietic stem cell transplantation (HSCT) recipients requiring intensive care unit (ICU) admission early after transplantation have a poor prognosis. However, many studies have only focused on allogeneic HSCT recipients. OBJECTIVES: To describe the characteristics of HSCT recipients admitted to the ICU shortly after transplantation and assess differences in 1-year mortality between autologous and allogeneic HSCT recipients. DESIGN AND SETTING: A single-center retrospective cohort study in a cancer center in Brazil. METHODS: We included all consecutive patients who underwent HSCT less than a year before ICU admission between 2009 and 2018. We collected clinical and demographic data and assessed the 1-year mortality of all patients. The effect of allogeneic HSCT compared with autologous HSCT on 1-year mortality risk was evaluated in an unadjusted model and an adjusted Cox proportional hazard model for age and Sequential Organ Failure Assessment (SOFA) at admission. RESULTS: Of the 942 patients who underwent HSCT during the study period, 83 (8.8%) were included in the study (autologous HSCT = 57 [68.7%], allogeneic HSCT = 26 [31.3%]). At 1 year after ICU admission, 21 (36.8%) and 18 (69.2%) patients who underwent autologous and allogeneic HSCT, respectively, had died. Allogeneic HSCT was associated with increased 1-year mortality (unadjusted hazard ratio, HR = 2.79 [confidence interval, CI, 95%, 1.48-5.26]; adjusted HR = 2.62 [CI 95%, 1.29-5.31]). CONCLUSION: Allogeneic HSCT recipients admitted to the ICU had higher short- and long-term mortality rates than autologous HSCT recipients, even after adjusting for age and severity at ICU admission.

Hematological abnormalities in patients of alcoholic chronic liver disease – A cross-sectional study in a tertiary care hospital in Eastern Zone of India

Background: Alcohol abuse is on increasing trend in world as well as in India, especially in young population. Long-term alcohol intake may leads to alcoholic chronic liver disease which may turns in to end stage liver diseases. Alcoholic chronic liver disease is associated with some hematological abnormalities which if detected at early stage may provide clear therapeutic implications in managing these patients and reducing the adverse events. Aims and Objectives: Our aim of the study was to identify various hematological abnormalities in patients of alcoholic chronic liver disease. Materials and Methods: This hospital-based cross-sectional study includes 100 randomly selected patients with alcoholic chronic liver disease attending Out-Patient Department and admitted in General Medicine ward of Burdwan Medical College satisfying the inclusion and exclusion criteria. Data were analyzed for hemoglobin (Hb), red blood cell (RBC), total leukocyte count (TLC), platelet count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), MCH concentration, and prothrombin time-international normalized ratio. The mean and standard deviation, percentages, and ratio were calculated and presented in the form of tables with the help of SPSS (IBM) ver-23. P < 0.05 was considered statistically significant. Results: Hematological abnormalities were found more with increased duration of alcohol consumption. Prolonged bleeding time was observed in 23% cases and prolonged clotting time was observed in 21% cases. Maximum patients belonged to Child–Pugh grade C. Hematological abnormalities were more in patients belonging to Child–Pugh grade C. Hb, RBC, platelet, and packed cell volume were significantly lower in patients belonging to Child–Pugh class C, whereas TLC, MCV, and MCH were significantly higher in class C. Conclusion: It can be concluded that related hematological changes, which are common in alcoholic chronic liver disease endanger the lives of these patients. They should be detected and corrected at earliest to minimize morbidity and mortality.

Spectrum-of-haematological-disorders-in-bone-marrow-aspiration-at-tertiary-care-hospital-jorhat

Anemia is a common symptom of haematological disorders in people of all ages .The spectrum of haematological disorders differs significantly between developing and industrialized countries. The primary use of bone marrow aspirate is for cytological examination. It enables study into the cellularity of the bone marrow as a whole, the detection of specific lesions, and the amount of infiltration by various disease entities. The aim of the study is toAims & objective: evaluate the spectrum of haematological disorders reported in bone marrow aspiration and to know the age and sex incidence. This prospective study is an observational study was conducted over a one-yearMaterials and methods: period on 73 patients and the spectrum of hematological disorders was studied on bone marrow aspiration smears. Conclusion: A thorough examination of the bone marrow is essential for diagnosing haematologic disorders. It is a simple and cost effective procedure which can be performed routinely without using any specialized equipment or a need of general anaesthesia

Comparative analysis between cytomorphology and flow cytometry methods in central nervous system infiltration assessment in oncohematological patients

ABSTRACT Introduction Oncohematological patients require the evaluation for possible infiltration of the central nervous system (CNS) by neoplastic cells at diagnosis and/or during the monitoring of the chemotherapeutic treatment. Morphological analysis using conventional microscopy is considered the method of choice to evaluate the cerebrospinal fluid (CSF) samples, despite technical limitations. Objective This study aimed to compare the performance of the cytomorphology and flow cytometric immunophenotyping (FC) in the detection of CNS infiltration. Method We evaluated 520 CSF samples collected from 287 oncohematological patients for whom the detection of neoplastic cells was simultaneously requested by cytomorphology and FC. Results Laboratory analyses revealed 435/520 (83.7%) conclusive results by the two methods evaluated, among which 385 (88.5%) were concordant. Discordance between the methods was observed in 50/435 (11.5%) samples, 45 (90%) being positive by FC. Furthermore, the FC defined the results in 69/72 (95.8%) inconclusive samples by cytomorphology. The positivity of FC was particularly higher among hypocellular samples. Among 431 samples with a cell count of < 5/μL, the FC identified neoplastic cells in 75 (17.4%), while the cytomorphology reported positive results in 26 (6%). Among the samples that presented adequate cell recovery for evaluation by both methods (506/520), the comparative analysis between FC and cytomorphology revealed a Kappa coefficient of 0.45 (CI: 0.37-0.52), interpreted as a moderate agreement. Conclusion The data showed that the CSF analysis by FC helps in the definition of CNS infiltration by neoplastic cells, particularly in the cases with dubious morphological analysis or in the evaluation of samples with low cellularity.

Exposição ambiental ao benzeno, parâmetros hematológicos e níveis urinários de ácido trans, trans-mucônico em uma comunidade da região Nordeste do Brasil / Environmental exposure to benzene, hematological parameters, and urinary levels of trans,trans-muconic acid in a community in the Northeast region of Brazil

Resumo Introdução O metabólito do benzeno ácido trans, trans-mucônico (t, t-MA) urinário é considerado bom bioindicador de exposição a níveis de benzeno no ar superiores a 0,50 ppm. Objetivo Determinar níveis urinários de ácido trans, trans-mucônico (t, t-MA) e investigar relação com potenciais fontes de exposição ao benzeno e associação com parâmetros hematológicos. Método Estudo seccional, com 150 moradores de Açailândia, Maranhão, Brasil. Utilizou-se questionário estruturado para caracterização sociodemográfica, ocupacional, dentre outras. Coletaram-se amostras de urina e sangue para determinar níveis de t, t-MA e realização de hemograma. As associações foram exploradas mediante regressão logística e linear múltipla. Resultados O t, t-MA foi detectado em 27% dos participantes, sendo a média da concentração 0,15 mg/g de creatinina. As alterações hematológicas mais frequentes foram bastonetes baixos (41%), eosinofilia (33%) e níveis reduzidos de hemoglobina (19%). Não encontrou-se correlação estatisticamente significativa entre t, t-MA e parâmetros do hemograma. Os fatores que influenciaram de forma significativa a excreção de t, t-MA foram cor da pele, prática regular de atividades de lazer com exposição a solventes orgânicos e consumo de refrigerante e refresco nas últimas 24 horas. Conclusão A população parece não estar exposta a concentrações elevadas de benzeno. Entretanto, o perfil hematológico revelou presença de alterações bioquímicas compatíveis com anemia e comprometimento imunológico.

Abstract Background The urine benzene metabolite trans,trans-muconic (t,t-MA) is considered a good bioindicator of exposure to benzene levels in the air above 0.50 ppm. Objective Determine urinary levels of trans, trans-muconic acid (t,t-MA) and investigate the relationship with potential sources of exposure to benzene and its association with hematological parameters. Method A sectional study was carried out with 150 residents of Açailândia, Maranhão, Brazil. A structured questionnaire was used for sociodemographic and occupational characterization, among others. Urine and blood samples were collected to determine t,t-MA levels and blood counts. Associations were explored using multiple linear and logistic regressions. Results The t,t-MA was detected in 27% of the participants, with an average concentration of 0.15 mg/g creatinine. The most frequent hematological changes were low rods (41%), eosinophilia (33%), and reduced hemoglobin levels (19%). No statistically significant correlation was found between t,t-MA and blood count parameters. The factors that significantly influenced the excretion of t, t-MA were skin color, regular practice of leisure activities with exposure to organic solvents, and consumption of soda and soft drinks in the last 24 hours. Conclusion The population does not appear to be exposed to high concentrations of benzene. However, the hematological profile revealed the presence of biochemical changes compatible with anemia and immunological impairment.

Pregnancy is a state characterized by physiological changes. These changes are interpreted by comparison between known reference values, which themselves depend on factors such as ethnicity, environment, diet, age, sex… However, the reference values being used in clinical practice in the Democratic Republic of Congo (DRC) are derived from general populations. Therefore, this study aimed to determine the reference values of hematological parameters among pregnant women in Kinshasa. Methods. This analytical cross-sectional study recruited pregnant women in Kinshasa, DRC from December 2022 to April 2023. The Complete blood count was carried out for all participants using Mindary BC-5150 hematology analyzer. The mean, median, and reference values were determined using SPSS version 23. Results. A Total of 451 healthy pregnant women were enrolled in the study. The participant age range was from 18 to 49 years old, 386 (85.6 %) were married and 152 (33.75) paucipare. The defined Reference values were: RBC : 2,79-4,78 x106/µl , Hb : 10,5-12,7 g/dl, HCT :24,3-38,9 %, MCV : 84,3-99,9 fl, MCH : 25,8-29,8 pg, MCHC : 30,0-36,1 g/dl, WBC : 2,83-10,56 x103/µl , Neutrophils :0,8-7,68 x103/µl , lymphocytes : 0,72-2,83 x103/µl , Monocytes :0,10-1,06 x103/µl , Eosinophils : 0,0-0,32 x103/µl , Basophils : 0,0-0,03 x103/µl , Platelet count :189-322 x103/µl, MPV : 7,9-12,6 fl. Conclusion. Changes were observed in hematological parameters between different trimesters of the pregnancy. Considerable differences were also observed when comparing reference values in the present study to those from studies conducted in other countries.

La grossesse est un état caractérisé par des changements physiologiques. Ces changements sont interprétés par comparaison à des valeurs de référence connues qui dépendent elles-mêmes de l'ethnie, de l'environnement, de l'alimentation, de l'âge, du sexe… Cependant, les valeurs de référence utilisées dans la pratique clinique proviennent de populations générales. La présente étude a visé à déterminer les valeurs de référence des paramètres hématologiques chez les femmes enceintes dans la ville de Kinshasa. Méthodes. Cette étude transversale et analytique a recruté des femmes enceintes à Kinshasa, de décembre 2022 à avril 2023. L'hémogramme a été réalisé chez toutes les participantes sur l'analyseur d'hématologie Mindray BC-5150.

Prise en charge des hémopathies malignes au centre national d'oncologie médicale et de radiothérapie Alassane Ouattara d'Abidjan / Managem ent of hem atologic neoplasm sat the Centre National d'Oncologie Médicale et de Radiothérapie Alassane Ouattara ofAbidjan

Introduction. Les hémopathies malignes sont des proliférations anormales et anarchiques de cellules hématopoïétiques à point de départ médullaire ou périphérique. Notre étude qui avait pour objectif de faire le bilan de la prise en charge des hémopathies malignes au Centre national d'oncologie médical et de radiothérapie Alassane Ouattara. Méthodes. Il s'agissait d'une étude rétrospective descriptive d'une durée de 2 ans 3 mois allant du 1er janvier 2018 au 31 Mars 2020 portant sur 80 dossiers de malades porteurs d'hémopathies malignes et prise en charge dans le centre. Résultats. Notre étude a permis de recenser 2,2% d'hémopathies malignes sur les 3650 cas de pathologies cancéreuses recensées au CNRAO, soit une incidence 26,66 cas/an avec un sex-ratio 1,2. Les syndromes lymphoprolifératifs (SLP) sont les plus fréquents (96,25 %), sous trois principales formes: lymphomes malins non hodgkiniens (LMNH) non Burkitt (51,25%), leucémie myéloïde chronique (20%) et le myélome multiple (16,25%). Les LMNH représentent 51,25% des HM recensées avec 41,46 % de lymphomes de haut grade de malignité. La chimiothérapie était de mise chez tous nos patients. Ainsi sur 41 cas de LMNH, seulement 12 (29,27%) ont bénéficié du protocole R-CHOP. On notait 46,34% de réponse complète. Dans notre étude, le LH représentait 8,75% il était traité à 71,43% avec le protocole ABVD avec une réponse complète chez 6 patients. 37,5% des patients porteurs de leucémie myéloïde chronique ont reçu le Rituximab; ils ont été traités par les protocoles COP (31,25%), CHOP (31,25%), RCVP (12,5%) et R-CHOP (25%). La réponse thérapeutique était complète à 68,75%. Le protocole utilisé dans le traitement du myélome multiple a été le VMCD-REV à 76,92% avec pour réponse thérapeutique complète chez 6 patients, 3 réponses partielles et 4 en cours de traitement. Conclusion. Les SLP qui sont les plus fréquents des HM avec trois principales formes: LMNH non Burkitt, leucémie myéloïde chronique et myélome multiple. Nous avons cependant des difficultés quant à la mise en route de la chimiothérapie.

Introduction. Hematologic neoplasms are abnormal and anarchic proliferations of hematopoietic cells with a medullary or peripheral starting point. Our study aimed to report the management of hematological malignancies at the Centre National d'Oncologie Médicale et de Radiothérapie Alassane Ouattara (CNRAO). Methods. This was a descriptive retrospective study lasting 2 years 3 months from January 1st, 2018 to March 31st, 2020 concerning 80 patients with hematologic neoplasms who were managed in the CNRAO. Results. Hematologic neoplasms represented 2.2% of cancers (80/3650) at CNRAO, giving an annual incidence of 26.66 cases. The sex ratio was 1.2. Lymphoproliferative syndromes were the most common subgroups (96.25%). These were mainly non-Burkitt non Hodgkin lymphoma (51.25%), high grade lymphomas (41.46%), chronic lymphocytic lymphoma (20%) and multiple myeloma (16.25%). Chemotherapy was administered to all patients. Among 41 cases of non-Hodgkin lymphoma, 12 (29.27%) benefited from the R-CHOP protocol and full response was observed in 46.34% of them. We found 7 patients with Hodgkin lymphoma (8.75%) and the ABVD protocol was used for 6 cases (71.43%). Six out of these seven patients were in complete response. Among the 16 patients with chronic lymphocytic leukemia, 6 (37.5%) received Rituximab. The distribution of the patients with chronic lymphocytic leukemia was as follows: COP 31.25%, CHOP 31.25%, RCVP 12.5% and R-CHOP 25% and 68.75% had full response. The most common treatment protocol for multiple myeloma was VMCD-REV (76.92%). Six patients had complete response, 3 had partial response and 4 were in the course of treatment. Conclusion. In our practice, hematologic neoplasms are mainly lymphoproliferative syndromes and the most common varieties are non-Burkitt non Hodgkin lymphoma, high grade lymphomas, chronic lymphocytic lymphoma and multiple myeloma. We have difficulties in getting chemotherapy started.

Hémopathies malignes de l'adulte à Kinshasa: analyse documentaire d'une série des cas de 2011 à 2021 / Hematological malignancies in adults in Kinshasa: retrospective serial cases from 2011 to 2021

Contexte et objectif. Les hémopathies malignes (HM) constituent un problème majeur de santé publique en Afrique sub-saharienne où les moyens de prise en charge sont limités. L'objectif de l'étude était de décrire les aspects diagnostiques, thérapeutiques et évolutifs observées dans la prise en charge des HM en milieu hospitalier de Kinshasa. Méthodes. Etude observationnelle historique de type suivi des cas d'HM hospitalisés, dans formations sanitaires de Kinshasa entre les 1er janvier 2011 et 31 décembre 2021. Seuls les patients âgés de plus de 18 ans ont été inclus. Les paramètres d'intérêt étaient englobés les données sociodémographiques, cliniques, biologiques, d'imagerie, du myélogramme, de l'analyse histopathologique des pièces biopsiques ganglionnaires ou extra ganglionnaires, le type de chimiothérapie et de la survie à 6 mois. Les tests de chi-carré et de Student ont comparé respectivement les proportions et les moyennes. L'analyse de Kaplan Meier et la régression de Cox ont respectivement décrit la survie et recherché les facteurs associés à la mortalité à 6 mois. Résultats.Sur 2678 patients suspects d'HM, seuls de 250 patients (9,3%, âge moyen 47,6 ± 15,8 ans, 62,4% d'hommes) ont eu un bilan de confirmation. Les adénopathies périphériques (54 %), la fièvre au long cours (48 %) et la poly transfusion (29 %) étaient les principaux motifs de consultation. Les perturbations hématologiques rencontrées étaient l'anémie (72 %), la thrombopénie (50 %), l'hyperleucocytose ( 0 %) et la leucopénie ( 0 %). Les syndromes lymphoproliferatif (68 %) étaient plus fréquents et répartis en lymphomes non hodgkiniens (50 %), Lymphome hodgkinien (27%) et myélome multiple (15 %). Les leucémies aigues venaient en deuxième position (12 %) suivi des syndromes myélodysplasiques (11 %) et des syndromes myéloprolifératifs (8 %). 61 % des patients ont bénéficié de la chimiothérapie. Durant les 6 premiers mois de prise en charge, la létalité globale était de 58,4 %. Conclusion. En milieu hospitalier de Kinshasa, très peu de patients suspects d'HM bénéficient d'une mise au point complète et de la chimiothérapie. Les adultes jeunes, surtout les hommes, sont très affectés et plus de la moitié d'entre eux décèdent endéans 6 mois. L'amélioration de l'accessibilité à la chimiothérapie et du plateau technique permettra une réduction de la létalité.
