ABSTRACT

ABSTRACT There have been significant improvements in therapeutic options for relapsed multiple myeloma (MM) over the past two decades, with many novel agents including proteasome inhibitors, immunomodulatory agents, and more recently monoclonal antibodies demonstrating efficacy in this setting. However, there is a paucity of real-world data comparing outcomes seen in patients treated with novel agents as opposed to older agents. We report a historical single center cohort of patients diagnosed with myeloma between the years 1991-2012 in order to explore possible differences in outcomes. A total of 139 patients who underwent stem cell transplantation were included in our study. In our study, 88 patients were treated with cyclophosphamide and steroids alone at relapse whereas 51 patients were treated with Len-Dex. In the multivariate analysis, TTNT was shorter for patients who received Cyclo compared to Len-Dex (HR = 1.74; 95% CI, 1.01-2.99; p = 0.04); however, we could not detect an overall survival benefit (HR = 1.20; 95% CI 0.63-2.29; p = 0.57). Adverse event rates were similar in the two groups. In this retrospective single center analysis, Len-Dex was associated with longer TTNT compared with Cyclo at first relapse following autoSCT in MM; however its effect on overall survival in this setting was less clear.

ABSTRACT

Abstract Complete hydatidiform mole (CHM) is a rare type of pregnancy, in which 15 to 20% of the cases may develop into gestational trophoblastic neoplasia (GTN). The diagnostic of GTN must be done as early as possible through weekly surveillance of serum hCG after uterine evacuation.We report the case of 23-year-old primigravida, with CHM but without surveillance of hCG after uterine evacuation. Two months later, the patient presented to the emergency with vaginal bleeding and was referred to the Centro de Doenças Trofoblásticas do Hospital São Paulo. She was diagnosed with high risk GTN stage/score III:7 as per The International Federation of Gynecology and Obstetrics/World Health Organization (FIGO/WHO). The sonographic examination revealed enlarged uterus with a heterogeneous mass constituted of multiple large vessels invading and causing disarrangement of the myometrium. The patient evolved with progressive worsening of vaginal bleeding after chemotherapy with etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO) regimen. She underwent blood transfusion and embolization of uterine arteries due to severe vaginal hemorrhage episodes, with complete control of bleeding. The hCG reached a negative value after the third cycle, and there was a complete regression of the anomalous vascularization of the uterus as well as full recovery of the uterine anatomy. The treatment in a reference center was essential for the appropriate management, especially regarding the uterine arteries embolization trough percutaneous femoral


Resumo Mola hidatiforme completa (MHC) é um tipo raro de gravidez, na qual 15 a 20% dos casos podem desenvolver neoplasia trofoblástica gestacional (NTG). O diagnóstico de NTG deve ser feito o mais cedo possível, pelo monitoramento semanal do hCG sérico após esvaziamento uterino. Relatamos o caso de uma paciente primigesta, de 23 anos de idade, com MHC, sem vigilância de hCG após esvaziamento uterino. Dois meses depois, a paciente compareceu na emergência com sangramento vaginal, sendo encaminhada ao Centro de Doenças Trofoblásticas do Hospital São Paulo, onde foi diagnosticada com NTG de alto risco, estádio e score de risco III:7 de acordo com a The International Federation of Gynecology and Obstetrics/Organização Mundial de Saúde (FIGO/OMS). O exame ultrassonográfico revelou útero aumentado com uma massa heterogênea constituída pormúltiplos vasos volumosos invadindo e desestruturando o miométrio. A paciente evoluiu com piora progressiva do sangramento vaginal após quimioterapia com o regime etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO). Ela foi submetida a transfusão de sangue e embolização das artérias uterinas devido aos episódios graves de hemorragia vaginal, com completo controle do sangramento. O hCG atingiu valor negativo após o terceiro ciclo, havendo regressão completa da vascularização uterina anômala, assim como recuperação da anatomia uterina. O tratamento em um centro de referência permitiu o manejo adequado, principalmente no que se refere à embolização das artérias uterinas através da punção percutânea da artéria femoral, que foi crucial para evitar a histerectomia, permitindo a cura da NTG e a manutenção da vida reprodutiva.

ABSTRACT

Introducción: La esclerosis sistémica es una enfermedad autoinmune del tejido conectivo donde ocurre inicialmente la vasculopatía y persiste durante toda la enfermedad. El índice de actividad revela un periodo crítico de la enfermedad. Objetivo: Evaluar la evolución clínica del índice de actividad de pacientes con esclerosis sistémica para determinar si el esquema terapéutico aplicado disminuye los síntomas de actividad sistémica. Métodos: Estudio cuasi experimental terapéutico de 31 pacientes atendidos en el Hospital Lucía Íñiguez Landín de Holguín que se dividieron en dos grupos según las etapas clínicas obtenidas del índice de desarrollo integral desde marzo del 2013 hasta marzo del 2016: el grupo A (etapas clínicas I y II) con 16 pacientes y el grupo B (etapas clínicas III y IV) con 15 pacientes. La evolución se evaluó según variables del instrumento al inicio, a los 6 y 12 meses de aplicado el esquema terapéutico. Se utilizó la prueba T o la prueba exacta de Fisher cuando los valores eran igual a 3 o menores. El cálculo de la media, análisis porcentual y la prueba de Wilcoxon se usaron para conocer la relación de variables en el tiempo. Resultados: El esquema terapéutico aplicado, previa validación, mejoró el índice de actividad de los pacientes de ambos grupos A y B (en etapas clínicas tempranas y tardías). Al evaluar el índice de actividad, en esta serie predominó la actividad moderada, tanto a los 6 como a los 12 meses durante el tratamiento médico. En ambos grupos la mejoría del índice de actividad fue significativa, tanto para la actividad moderada como para la intensa, más notable a partir de los 12 meses con p≤0,05 para el grupo A. Hubo baja susceptibilidad para la mejoría de los sistemas gastrointestinal y respiratorio, en el trascurso de la evaluación de este índice. Conclusiones: Se alcanzó mejoría en el índice de actividad de pacientes con esclerosis sistémica, con el esquema terapéutico aplicado, con estabilidad clínica y humoral desde las etapas iniciales de la enfermedad(AU)


Introduction: The systemic sclerosis is an autoimmune disease of the connective tissue where the vasculopathy happens initially and persist during all the disease. The immune component starts since the inflammatory process triggers off but he diminishes until you dwell on the evolutionary course and it is substituted for fibrosis, this ends pathogenic acquires great significance in the process. The index of activity reveals a critical period of the disease. Objective: Evaluating patients' clinical evolution of the index of activity with systemic sclerosis with the applied therapeutics. Methods: The study was quasi-experiences (or secondary prevention). In order to determine if the therapeutic applied scheme decreases symptomatology of its systemic activity. You started in March of the 2013 to March of the 2016, with duration of 24 months. They were 31 patients that split into two groups according to the clinical stages obtained of Comprehensive Development Index. In the group to (clinical stages I and II) 16 patients and in the group B (clinical stages III and IV) 15 patients. The evolution evaluated according to variables of the instrument of evaluation the start, to the six and 12 months itself of once the therapeutic scheme was applied. The T utilized the proof itself, or exact Fisher's proof when moral values were all the same or minor to three, the statistical significance determined in p≥ 0.05 itself. The calculation of the stocking, percentage analysis, and Wilcoxon's proof to know the relation of variables through the time. Results: The therapeutic applied scheme, previous validation, you improved the index of activity of the patients of both groups A and B that is in clinical premature and overdue stages. In the activity moderated for the group A statistical significance for system microvascular (0.023) and respiratory (0.025) to the six months, and to the 12 months' skin (0.023) and microvascular (0.006). For the intense activity significant improvement to the six months for muscleskelettic (0.005) and rheumatoid positive factor (0.008), to the 12 months' significant improvement for muscleskelettic (0.004); and examine of laboratory like erythrocyte sedimentation rate (0.008) circulating immune complexes (0.005), and rheumatoid factor (0.003). For the group B in the moderate activity significant improvement for respiratory system existed (0.014), and cardiovascular (0.020) that kept to the 12 months, added up its digestive system (0.008). Evident level improvement of skin (0.004), circulating immune complexes (0.008) and rheumatoid factor were caught up within the intense activity to the 12 months (0.014). Conclusions: Improvement in the index of activity of patients with systemic sclerosis, with the therapeutic scheme applied, with clinical stability and humoral from initial stages of the disease was caught up with(AU)

ABSTRACT

El linfoma de Burkitt es una neoplasia altamente agresiva y es un tipo raro de linfoma no Hodgkin localizado. Aunque los niños son los más frecuentemente afectados, en adultos ocurren principalmente durante el embarazo o el puerperio. La mama rara vez constituye la localización primaria del linfoma no Hodgkin. Se presenta un caso de linfoma de Burkitt primario de mama durante el embarazo. Paciente de 37 años con embarazo de 24 semanas quien presentó aumento de volumen difuso de mama derecha. La mama estaba aumentada de tamaño, dolorosa y homogénea con tumoración elástica y firme. La ecografía demostró inflamación difusa con tumoración heterogénea e hipoecoica con contornos ligeramente irregulares, marcadores tumorales estaban normales las pruebas serológicas fueron negativas. La biopsia de la lesión mostró tejido mamario reemplazado por células linfoideas de tamaño mediano con citoplasma basófilo y múltiples vacuolas. Estudios inmunohistoquímicos fueron positivos para el antígeno leucocitario común, CD10, CD20, CD43, Bcl-6. El análisis cromosómico reveló que más del 90 % de las células neoplásicas exhibieron translocación t llevando al diagnóstico final de linfoma de Burkitt de mama. Luego de evaluar las posibilidades terapéuticas y del consentimiento de la paciente se inició tratamiento citostático sistémico. Los linfomas primarios de mama son extremadamente raros. El linfoma de Burkitt primario de la mama es mucho menos común que los otros linfomas. Los métodos de clasificación, detección y tratamiento de esta afección siguen siendo objeto de debates e investigaciones(AU)


The Burkitt's lymphoma is a highly aggressive neoplasm and is a rare type of localized non-Hodgkin lymphoma. Although children are the most frequently affected, in adults they occur mainly during the pregnancy or the puerperium. The breast rarely constitutes the primary location for non-Hodgkin lymphoma. The study of a case of primary Burkitt lymphoma of the breast during pregnancy is presented. This is a 37 year old patient with a 24 week pregnancy who presented a diffuse increase in the volume of the right breast. The breast was enlarged, painful and homogeneous with a firm, elastic mass. The ultrasonography showed diffuse inflammation with a heterogeneous and hypoechoic tumor with slightly irregular contours. The tumor marker values were normal and the serological tests were negative. The biopsy of the lesion showed breast tissue replaced by medium-sized lymphoid cells with basophilic cytoplasm and multiple vacuoles. Immunohistochemically studies were positive for the common leukocyte antigen, CD10, CD20, CD43, Bcl-6. The chromosomal analysis revealed that more than 90 % of neoplastic cells exhibited t translocation leading to the final diagnosis of Burkitt lymphoma of the breast. After evaluating the therapeutic possibilities and the patient's consent, systemic cytostatic treatment was started. Primary breast lymphomas are extremely rare. The primary Burkitt lymphoma of the breast is much less common than other lymphomas. The methods of classification, detection, and the treatment of this condition continue to be the subject of debate and research(AU)

ABSTRACT

ABSTRACT Objective: To observe clinically, in rabbits, the side effects of topical injection of subconjunctival cyclophosphamide, studying its role as an antifibrotic drug. Methods: Prospective study in 20 albino rabbits of New Zealand race. All rabbits were treated with cyclophosphamide, 10mg/ml in a volume of 0.3 ml, in the left eye through subconjunctival injection. They were evaluated for 1, 7, 30, and 60 days after the procedure. All the animals were examined for the detection of ocular reactions such as necrosis, hyperemia, chemosis, secretion, opacity, and iritis. Other side effects as changes in the behavior, in the feed, and the water consumption were also evaluated. Results: It was observed that from the 20 rabbits studied, three rabbits (15%) showed side effects only at the 24 hours analysis. One rabbit (5%) presented hyperemia, one rabbit (5%) had hyperemia associated with iritis, and one rabbit (5%) presented hyperemia associated with secretion. These reactions were not observed at 1, 7, 30, and 60 days. Conclusion: Cyclophosphamide subconjunctival injection induces minor side effects on the conjunctiva of rabbits such as hyperemia, associated with iritis and secretion.


RESUMO Objetivo: Observar clinicamente os efeitos colaterais de injeção subconjuntival de ciclofosfamida, pensando em sua ação como um agente antifibrótico. Métodos: Estudo prospectivo realizado com 20 coelhos albinos da raça Nova Zelândia. Todos os coelhos foram submetidos a 0,3 ml de injeção subconjuntival de ciclofosfamida 10mg/ml no olho esquerdo e foram avaliados de acordo com os efeitos locais no primeiro dia após a injeção, 7, 30 e 60 dias. Foram examinados para detecção de reações oculares como necrose, hiperemia, quemose, secreção, opacidade corneana, irite além de alterações comportamentais e variação no consumo de água e alimentação. Resultados: Dos 20 coelhos estudados, apenas 3 apresentaram reações oculares e somente na leitura de 24 horas. Um coelho (5%) apresentou hiperemia, 1 coelho (5%) apresentou hiperemia associada a presença de irite e 1 coelho (5%) apresentou hiperemia associada a presença de secreção. As reações não foram mais observadas durante os exames de 7, 30 e 60 dias. Conclusão: A ciclofosfamida subconjuntival causou poucos efeitos colaterais na conjuntiva dos coelhos. Os únicos efeitos encontrados foram hiperemia, irite e secreção.

ABSTRACT

RESUMO Objetivo: Avaliar a inibição da proliferação de fibroblastos in vitro das conjuntivas obtidas através de exérese de pterígios de pacientes utilizando mitomicina C (MMC) e ciclofosfamida (CF). Métodos: Os pterígios foram retirados de 7 pacientes e submetidos a cultivo celular. Após o cultivo, 3 fragmentos de dimensões iguais deste material foram colhidos de áreas adjacentes do pterígio removido de cada paciente. Eles foram randomicamente selecionados de tal forma que: um fragmento de cada paciente foi exposto: ao meio de cultura (grupo controle), a MMC e a CF por igual período de tempo nas concentrações de 0,4 mg/ml e 10 mg/ml respectivamente. Após este período realizou-se a contagem celular de fibroblastos destes 3 grupos. Cada grupo continha 7 fragmentos. Resultados: Com a utilização da MMC tivemos uma taxa de 95% da inibição da proliferação dos fibroblastos, enquanto com a CF 100%. Conclusões: Ambas as drogas apresentaram elevada taxa da inibição da proliferação de fibroblastos, porém a CF apresentou inibição maior que a MMC.


Abstract Objective: To evaluate the inhibition of fibroblast proliferation in vitro of conjunctiva obtained by excision of pterygium from patients using mitomycin (MMC) and cyclophosphamide (CF). Methods: Pterygiums were removed from 7 patients and subjected to cell culture. After cell cultivation, 3 fragments of equal dimensions of these tissues were collected from adjacent areas of each patient removed pterygium. They were randomly selected in such a way that one fragment of each patient was exposed to: the culture medium (group control), to MMC and to CF for an equal period of time at concentrations of 0,4 mg/dl and 10 mg/dl respectively. After this period, the fibroblast cell count of these groups were performed. Each group had seven fragments. Results: With the use of MMC we had a 95% rate of inhibition of fibroblast proliferation, while with CF 100%. Conclusion: Both drugs showed a high rate of inhibition of fibroblast proliferation, but CF showed greater inhibition than MMC.

ABSTRACT

Abstract Background: Systemic sclerosis (SSc) Is a clinically complex and challenging disease, that leads to skin fibrosis. Its most frequent complication is interstitial lung disease (ILD), which leads to a worse prognosis. In this situation, cyclophosphamide is considered the gold standard for its treatment, despite the controversies regarding its efficacy and toxicity. However, studies using rituximab (RTX) have shown that this drug may be a promising therapeutic option. Objectives: This paper objective was to analyze the scientific evidence on the RTX effects on SSc. Methods: A systematic review (SR) was performed including clinical trials (CTs) on the use of RTX in SSc, published up to May 2020. The studies were identified through systematic searches in bibliographic databases using a predefined search strategy. The following databases were used: PUBMED, SCOPUS, SCIELO, LILACS, SCIENCE DIRECT, WEB OF SCIENCE, COCHRANE, WHOLIS, PAHO and EMBASE. Also, a manual search was performed. The methodological quality of the studies was determined using Jadad scale, Risk of Bias Tool (RoB 2.0) and Risk of Bias in Non-Randomized Studies - of Interventions tool (ROBINS-I). A meta-analysis of the randomized CTs was performed, using Review Manager. Results: Ten CTs were included in this SR. Of these, three were randomized and seven were non-randomized. Five showed a statistically significant improvement in forced vital capacity (FVC) at some time during follow-up. Regarding the skin, eight studies showed statistically significant improvements according toa the modified Rodnan skin score. The meta-analysis found positive effects of RTX in SSc, with a statistical significance for lung disease. Conclusion: Rituximab is a promising strategy for the SSc-associated ILD and cutaneous fibrosis treatment. PROSPERO registration number: CRD42019132018.(AU)

ABSTRACT

BACKGROUND@#With current chemotherapy treatment, >90% of survival has been obtained for Burkitt lymphoma (BL). In this study, the demographic characteristics and treatment outcomes are presented for 78 children in China with central nervous system-positive (CNS+) BL.@*METHODS@#This retrospective study consecutively enrolled 78 CNS+ BL patients in Beijing Children's Hospital (BCH) from 2007 to 2019 who received the BCH B-cell non-Hodgkin's lymphoma regimen (modified by French-American-British mature lymphoma B-cell 96 [FAB/LMB96] C1 arm ± rituximab). Clinical characteristics, methods of disease detection in the CNS, and outcomes were evaluated. Univariate and multivariate analyses were used to assess prognostic factors.@*RESULTS@#The median age of 65 boys and 13 girls at the time of diagnosis was 5.7 years (ranging from 1 to 14 years). Patients were followed up for a median time of 34 months (ranging from 1 to 72 months). Bone marrow invasion was found in 38 (48.7%) patients. There were 48 (61.5%), 44 (56.4%), and 25 (32%) patients with cranial nerve palsy, intracerebral mass (ICM), and para-meningeal extension, respectively. Abnormal cerebrospinal fluid (CSF) morphology and CSF immunophenotype appeared in 15 (19.2%) and 15 (19.2%) patients, respectively. There were 69 (88.5%) patients treated with chemotherapy combined with rituximab, and nine patients were treated solely with chemotherapy. Finally, five patients died of treatment-related infection, recurrence occurred for 13, and one developed a second tumor. The 3-year overall survival and event-free survival rates were 78.9% ± 4.7% and 71.4% ± 6.0%, respectively. Treatment with chemotherapy only, ICM positivity, and >4 organs involved at diagnosis were independent risk factors.@*CONCLUSIONS@#Rituximab combined with a modified LMB96 regimen has greatly increased the efficacy of treatment for Chinese children with CNS+ BL, and with the continuous collection of outcome data, treatment-related complications are decreasing. For further verification, a large sample multicentre randomized controlled study should be performed to explore a treatment scheme for Chinese children with even greater efficacy.

ABSTRACT

OBJECTIVE@#To evaluate the safety and efficacy of BUCY (busulfan and cyclophosphamide) conditioning regimen for autologous hematopoietic stem cell transplantation (ASCT) in patients with multiple myeloma (MM).@*METHODS@#The clinical data of 72 MM patients received transplantation in the Hematology Department of the First Affiliated Hospital of Soochow University from May 2012 to June 2015 were retrospectively analyzed. Among them, 36 patients received BUCY conditioning regimen while the others received high-dose melphalan (HDM) conditioning regimen. The complication, post-transplantation hematopoietic reconstitution and efficacy between the two groups were compared.@*RESULTS@#There were no significant differences in sex, age, isotype, stage, induction therapy, mobilization method and proportion of conditioning regimen with Bortezomib between the two groups. The median time of neutrophil engraftment for the patients in BUCY and HDM groups was 10 (8-17) and 10 (9-13) d (P=0.046), and the median time of platelet engraftment was 10 (8-18) and 11 (9-47) d (P=0.017), respectively. The transplant related mortality of the patients in both groups was 2.7%. The CR rates of the patients after ASCT (38.9% and 50.0%) were higher than those before ASCT (27.8% and 19.4%) in the two groups. For the patients in BUCY group, the median follow-up time was 45 (0-61) months. Fifteen patients (41.7%) achieved disease progression. While for the patients in HDM group, the median follow-up time was 52(0-75) months. Twenty-two patients (61.1%) achieved disease progression.@*CONCLUSION@#The BUCY conditioning regimen is a safe and effective therapy for ASCT in patients with MM. Besides, in terms of safety and efficacy, BUCY regimen is not inferior to HDM regimen. BUCY regimen may replace HDM regimen as a standard conditioning regimen for ASCT in MM.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of CHOP regimen based on doxorubicin hydrochloride liposome in the initial treatment of elderly patients with diffuse large B-cell lymphoma (DLBCL).@*METHODS@#Thirty-one patients with DLBCL treated from January 1, 2012 to December 31, 2019 were analyzed retrospectively, their median age was 83 (71-95) years old, and all of them were in Ⅲ-Ⅳ stage, including 17 cases who had international prognostic index (IPI) ≥ 3. The patients were treated with R-CHOP and CHOP regimens based on doxorubicin hydrochloride liposome. The efficacy and safety were evaluated during and after treatment.@*RESULTS@#A total of 219 chemotherapy cycles and 7 median cycles were performed in 31 patients. The overall response (OR) rate and complete remission (CR) rate was 80.7% (25/31) and 61.3% (19/31), respectively, as well as 2 cases (6.5%) stable, 4 cases (12.9%) progressive. The main toxicities were as follows: the incidence of grade Ⅲ -Ⅳ neutropenia was 29% (9/31); two patients (6.5%) developed degree Ⅰ-Ⅱ cardiac events, which were characterized by new degree Ⅰ atrioventricular block; there were no cardiac events requiring emergency treatment and discontinuation of chemotherapy. The 1-year, 2-year and 3-year overall survival rate was 83.9%, 77.4% and 61.3%, respectively. The 1-year, 2-year and 3-year progression-free survival rate was 77.4%, 64.5% and 61.3%, respectively.@*CONCLUSION@#The chemotherapy regimen based on doxorubicin hydrochloride liposome has better efficacy and higher cardiac safety for elderly patients with DLBCL.

ABSTRACT

Post-transplantation cyclophosphamide (PT-Cy) alone or in combination with other immunosuppressive drugs has emerged as a promising strategy in the setting of allogeneic hematopoietic stem cell transplantation. Improved survival rate was reported in lymphoid malignancies following PT-Cy strategy compared with myeloid disease in non-myeloablative bone marrow transplant setting. Thus, we aimed to evaluate the safety and efficacy of PT-Cy combined with cyclosporine as graft-versus-host disease (GVHD) prophylaxis after myeloablative conditioning and T cell-replete peripheral stem cell transplantation in lymphoid malignancies. This single-arm phase II clinical trial (NCT01435447) involving 31 adult patients was conducted from January 2013 to June 2018. The donor-type neutrophil engraftment rate was 100%, and the overall incidence of grade II to IV and grade III to IV acute GVHD was 39% and 24%, respectively. The cumulative incidence rates of chronic GVHD (35%), including moderate to severe forms (10%), were reduced compared with those of the historical group (P = 0.03 and P = 0.04, respectively). With a median follow-up of 18 months, the estimated 2-year overall and event-free survival was 64.8% (95% confidence interval: 47.8%-86.7%) and 58.4% (95% CI: 41.9%-81.7%), respectively. The 2-year cumulative incidence rate of relapse was 19.5% (95% CI: 9.0%-35.8%), whereas the non-relapse mortality rate was 21.8% (95% CI: 11.3%-38.1%). These results demonstrated the feasibility of PT-Cy as GVHD prophylaxis in this clinical setting. This strategy could significantly reduce the incidence of chronic GVHD and its moderate to severe forms but not of acute GVHD and results in similar survival outcomes compared with the historical group. A prospective study with additional patients is warranted to confirm the role of PT-Cy in lymphoid malignancy.

ABSTRACT

La esclerosis sistémica (ES) es una enfermedad de causa desconocida, que se caracteriza por una producción exagerada de moléculas que componen la matriz extracelular. La disminución en la producción de óxido nítrico por las células endoteliales de la microvasculatura parece desempeñar un papel central en la patogenia de la enfermedad. Los resultados alcanzados en un estudio de serie de casos de un universo de 44 pacientes y muestra de 31, con baja incidencia de las causas neoplásicas en la muerte y como reacciones secundarias a tratamiento inmunosupresor con ciclofosfamida, según la conducta terapéutica aplicada, fue el motivo para la presentación de este trabajo, que reflejó la posible relación entre la esclerosis sistémica y las neoplasias. Se concluyó que la relación entre autoinmunidad y cáncer puede ser el resultado de un origen etiológico común (genético, hormonal, metabólico o factores ambientales) o un mecanismo de síndrome paraneoplásico. La enfermedad es terreno de riesgo para la ocurrencia de neoplasias, así como las neoplasias pueden inducir ES(AU)


The systemic sclerosis (SS) is a disease of unknown cause, that the fact that they fix the extra-cell womb characterizes itself for a production exaggerated of molecules. The decrease in the production of nitric oxide for the microvasculature's endothelial cells seems to play a central role in the pathogenesis of the disease. The results attained in 44 patients' study of series of cases of universe and inmunosupresor with cyclophosphamide according to therapeutic applied conduct shows of 31, with low incidence of the causes neoplastic in the death like secondary reactions and to treatment you went from motivation for the presentation of this work, that you reflected the possible relation between the systemic sclerosis and the neoplastic. It was concluded that the relation between auto-immunity and cancer can stem from an etiological common origin (genetic, hormonal, metabolic or environmental factors) or a mechanism of syndrome paraneoplastic. The disease is earthly of risk for neoplastic funny remark, the same way that the neoplastic can induce SS(AU)

ABSTRACT

ABSTRACT Background: The treatment of multiple myeloma (MM) has evolved significantly in the past decade, and new drug combinations have improved the response rates and prolonged survival. Studies comparing different induction chemotherapy regimens have shown that triple combinations have better results than double combinations. However, comparisons among different triple combinations are rare in the literature. Methods: We retrospectively compared two triple combinations comprising bortezomib, cyclophosphamide and dexamethasone (VCD) versus thalidomide, cyclophosphamide and dexamethasone (CTD), and aimed at identifying which of the two combinations would yield better response rates following four induction cycles prior to hematopoietic cell transplantation in patients with untreated multiple myeloma. Results: We retrospectively reviewed the medical records of 311 patients from 24 different centers.The VCD regimen was used as induction therapy by 117 (37.6%) patients, whereas 194 (62.4%) patients received the CTD regimen. After four cycles of induction on an intention-to-treat basis, 54% of the patients in the VCD group achieved at least very good partial response versus 42.8% in the CTD group (p = 0.05). We observed no difference in neuropathy or thrombotic events rates among the two regimens. Conclusion: Our results corroborate the superiority of the triple combination regimes containing bortezomib over the triple combination with thalidomide as pre ASCT induction therapy in MM.

ABSTRACT

Introducción: Las infecciones por virus o la reactivación de virus en estado latente son frecuentes durante el estado de inmunosupresión que sigue al trasplante de progenitores hematopoyéticos, y constituyen una causa importante de complicaciones, como la cistitis hemorrágica, que se caracteriza por disuria, polaquiuria, dolor abdominal y hematuria. La aparición precoz se asocia a la administración de citostáticos como la ciclofosfamida, y el comienzo tardío a la primoinfección o reactivación de virus como citomegalovirus, los adenovirus o los poliomavirus como el BK y el JC. Objetivo: Describir las características clínicas, la evolución y el manejo de la cistitis hemorrágica postrasplante. Casos clínicos: Se presentan dos pacientes con leucemia mieloide aguda que desarrollaron cistitis hemorrágica asociada a infección viral por virus BK y citomegalovirus después del trasplante haploidéntico con ciclofosfamida postrasplante. La cistitis hemorrágica de causa viral después del trasplante hematopoyético en estos pacientes estuvo asociada a una severa inmunosupresión, por lo que constituyó una complicación potencialmente letal. Los dos pacientes presentaron cistitis hemorrágica grado IV y fallecieron a pesar del tratamiento. Conclusiones: El trasplante haploidéntico con la administración de ciclofosfamida postrasplante incrementa la posibilidad de donantes de progenitores hematopoyéticos para los pacientes sin un hermano HLA idéntico pero el mayor nivel de inmunosupresión podría aumentar la incidencia de cistitis hemorrágica de causa viral(AU)


Introduction: Viral infections or latent-virus reactivation are frequent during the immunosuppressed cincition that follows hematopoietic stem-cell transplantation, and an important cause of complications, such as hemorrhagic cystitis, characterized by dysuria, urinary frequency, abdominal pain, and hematuria. The early appearance is associated with the administration of cytostatic drugs such as cyclophosphamide, and the late onset is associated with primary infection or reactivation of viruses such as cytomegalovirus, adenoviruses, or polyomaviruses such as BK and JC. Objective: To describe the clinical characteristics, evolution and management of post-transplant hemorrhagic cystitis. Clinical cases: The cases are presented of two patients with acute myeloid leukemia who developed hemorrhagic cystitis associated with viral infection by BK virus and cytomegalovirus after haploidentical transplantation with post-transplant cyclophosphamide. Viral hemorrhagic cystitis after hematopoietic transplantation in these patients was associated with severe immunosuppression, making it a potentially lethal complication. Both patients presented grade IV hemorrhagic cystitis and died despite treatment. Conclusions: Haploidentical transplantation with the of post-transplant cyclophosphamide administration increases the possibility for donors of hematopoietic progenitor cells to patients without an identical HLA match, but the higher level of immunosuppression could increase the incidence of viral hemorrhagic cystitis(AU)
