Vacinas de DCs vêm sendo utilizadas como forma de tratamento imunoterápico adjuvante para várias neoplasias. Protocolos para geração dessas células têm sido desenvolvidos e o método ideal de produção para uso clínico ainda necessita ser definido. É fundamental a definição de protocolos e reagentes que ofereçam, a partir de células mononucleares do sangue periférico, células dendríticas seguras e funcionais para uso clínico. A suplementação de meios de cultura com soro de origem animal e humano leva á riscos de xenosensibilização e transmissão de doenças. O uso do soro autólogo parece oferecer menos riscos ao paciente, porém a presença de fatores imunossupressores nesse soro poderia interferir na qualidade das DCs produzidas. Vários tipos de meios livres de soro, baseados nas boas práticas de produção - "good manufacture practice" (GMP), têm sido utilizados recentemente e parecem ser uma opção viável. O objetivo desse estudo foi avaliar os resultados da diferenciação, maturação e funcionalidade de DCs de pacientes com LMA, produzidas em meios livres de soro e em meio suplementado com soro autólogo. Concluímos que os meios de cultura livres de soro foram eficientes na produção de DCs para fins imunoterápicos em pacientes com LMA. Em contrapartida, o uso de soro autólogo parece interferir na capacidade funcional das DCs geradas / Abstract: Dendritic cells (DCs) are the main antigen-presenting cells of the immune system, capable of stimulating T lymphocytes to initiate specific immune responses. Vaccines based on DCs have been used as a treatment adjuvant immunotherapy for various malignancies. Protocols for generating these cells have been developed and the optimal method of production for clinical use remains to be defined. There is a great interest in the definition of protocols and reagents providing from peripheral blood mononuclear cells, functional and safe dendritic cells for clinical use. Supplementation of culture media with serum from animal and human leads to reactions due the animal proteins and transmission of disease. The use of autologous serum seems to offer less risk to the patient, but the presence of immunosuppressive factors may affect the quality of the DCs produced. Several types of serum-free media, based on "good manufacture practice" (GMP), have been used recently and seem to be a viable option. The aim of this study was to evaluate the results of the differentiation, maturation and function of DCs from AML patients, generated in serum-free media and media supplemented with autologous serum. We concluded that the serum-free media were efficient in the production of DCs for immunotherapy in AML patients. However, the use of autologous serum appears to interfere with the functional capacity of generated DCs / Mestrado / Biologia Estrutural, Celular, Molecular e do Desenvolvimento / Mestra em Fisiopatologia Médica

<p>Uvod: Febrilna neutropenija, kao prvi znak infekcije, je česta komplikacija u fazi postterapijske aplazije kostne srži u obolelih od akutne nelimfoblastne leukemije. Klinička slika febrilne neutropenije može biti suptilna, a progresija u stanje septičnog &scaron;oka znatno brža nego kod imunokompetentnih bolesnika. Rana predikcija rizika od komplikacija febrilne neutropenije i uvođenje empirijske antibiotske terapije može da pobolj&scaron;a prognozu bolesnika. Insulinska rezistencija, dislipidemija i inflamacija masnog tkiva se javljaju u sklopu sistemske inflamacije. Njihova uloga i značaj kao potencijalnih faktora predikcije toka i ishoda febrilne neutropenije nisu ispitani. Ciljevi istraživanja: Ustanoviti promene pokazatelja stepena insulinske senzitivnosti, ukupnog holesterola, triglicerida, HDL - holesterola, LDL - holesterola, apolipoproteina A-I, lipoproteina (a) i adiponektina pre i u fazi febrilne neutropenije kod bolesnika sa akutnom nelimfoblastnom leukemijom. Uporediti vrednosti pokazatelja stepena insulinske senzitivnosti, ukupnog holesterola, triglicerida, HDL - holesterola, LDL - holesterola, apolipoproteina A-I, lipoproteina (a) i adiponektina bolesnika sa akutnom nelimfoblastnom leukemijom pre početka febrilne neutropenije i kontrolne grupe gojaznih. Uporediti vrednosti pokazatelja stepena insulinske senzitivnosti, ukupnog holesterola, triglicerida, HDL - holesterola, LDL - holesterola, apolipoproteina A-I, lipoproteina (a) i adiponektina bolesnika sa akutnom nelimfoblastnom leukemijom u fazi febrilne neutropenije i kontrolne grupe gojaznih. Utvrditi da li su pokazatelj stepena insulinske senzitivnosti, ukupni serumski holesterol, trigliceridi, HDL - holesterol, LDL - holesterol, apolipoprotein A-I, lipoprotein (a) i adiponektin bolesnika sa akutnom nelimfoblastnom leukemijom u fazi febrilne neutropenije u korelaciji sa vrednostima parametara inflamacije, njenim tokom i ishodom. Materijal i metode: Istraživanje je sprovedeno u Klinici za hematologiju i Klinici za endokrinologiju, dijabetes i bolesti metabolizma. Obuhvatilo je 60 ispitanika, od kojih je 30 ispitanika obolelo od akutne nelimfoblastne leukemije, a 30 ispitanika je činilo kontrolnu grupu gojaznih. Nakon uključivanja u istraživanje, ispitanicima su urađeni predviđeni pregledi i laboratorijske analize u cilju procene insulinske senzitivnosti, metaboličkog statusa i serumskog adiponektina. Navedena merenja su urađena pre hemioterapije i u febrilnoj neutropeniji. Zdravstveno stanje ispitanika je praćeno do kraja prve hospitalizacije. Statistička obrada je izvr&scaron;ena uz pomoć statističkog paketa Statistica. Podaci su predstavljeni tabelarno i grafički, a statistička značajnost je odreĎivana na nivou p &lt; 0.05. Rezultati: U febrilnoj neutropeniji bolesnika sa akutnom leukemijom je do&scaron;lo do razvoja insulinske rezistencije (t = - 2.43, p = 0.021), dislipidemije sa značajnim sniţenjem ukupnog holesterola (t = 3.59, p = 0.0012), LDL &ndash; holesterola (t = 3.56, p = 0.0013) i apoA &ndash; I (t = 2.27, p = 0.03). Oboleli od akutne nelimfoblastne leukemije u febrilnoj neutropeniji su razvili metaboličke promene viđene kod gojaznih osoba sa insulinskom rezistencijom. Nastanak i progresija insulinske rezistencije je bila u pozitivnoj korelaciji sa fibrinogenom kao pokazateljem težine inflamacije (r = 0.59, p &lt; 0.05) dok je apoA - I negativno korelirao sa CRP (r = - 0.37, p &lt; 0.05). Ispitanici sa nižom insulinemijom i vrednostima HDL - holesterola pre hemoterapije su imali značajno bolji tok febrilne neutropenije (t = -2.38, p = 0.024 vs. t = - 2.87, p = 0.007). Ispitanici sa većim indeksom telesne mase (BMI) i obimom struka imali su povoljniji ishod febrilne neutropenije (r = - 0.47, p &lt; 0.05 vs. r = - 0.40, p &lt; 0.05). Drugi pokazatelji insulinske senzitivnosti, metaboličkog statusa i adiponektin nisu značajno uticali na tok i ishod febrilne neutropenije. Normalna telesna masa pre hemioterapije, a u febrilnoj neutropeniji temperatura u trajanju dužem od 7 dana, niže vrednosti MASCC indeksa rizika, vi&scaron;e vrednosti CRP, vi&scaron;e vrednosti adiponektina, niže vrednosti Lp(a) i komplikovan tok febrilne neutropenije su bili prediktori lo&scaron;ije prognoze febrilne neutropenije. Zaključak: Pored klasičnih hematolo&scaron;kih parametara potrebno je uzeti u obzir antropometrijske karakteristike, redistribuciju masne mase, disfunkcionalnost masne mase, insulinsku rezistenciju i metaboličke parametre u cilju praćenja i predviđanja mogućih komplikacija i komorbiditeta.</p> / <p>Introduction: Febrile neutropenia is a common complication in posttreatment aplasia in patients with acute nonlymphoblastic leukemia. Its clinical manifestation can be subtle. However, it can progress to septic shock more quickly than in immunocompetent patients. Early prediction of complications and recognition of risk factors can improve outcome. Systemic inflammation is characterized by insulin resistance, dyslipidemia and adipocyte dysfunction. However, their importance in predicting complications and outcome of febrile neutropenia is not entirely known.<br />Aims: To determine changes in HOMA-IR, total cholesterol, triglycerides, HDL - cholesterol, LDL - cholesterol, apolipoprotein A-I, lipoprotein (a) and adiponectin in patients before chemotherapy and during febrile neutropenia. To compare HOMA-IR, total cholesterol, triglycerides, HDL - cholesterol, LDL - cholesterol, apolipoprotein A-I, lipoprotein (a) and adiponectin in patients before chemotherapy and the obese. To compare HOMA-IR, total cholesterol, triglycerides, HDL - cholesterol, LDL - cholesterol, apolipoprotein A-I, lipoprotein (a) and adiponectin in patients during febrile neutropenia and the obese. To determine whether HOMA-IR, total cholesterol, triglycerides, HDL - cholesterol, LDL - cholesterol, apolipoprotein A-I, lipoprotein (a) and adiponectin in febrile neutropenia are in correlation with the severity of the infection, appearance of complications and outcome. Materials and methods: The study was conducted at the Clinic for hematology and Clinic for endocrinology, diabetes, and metabolic disorders. 60 patients who fulfilled the inclusion criteria were included in the study. 30 patients had acute leukemia, and 30 were obese. Clinical and laboratory examination to assess insulin sensitivity, metabolic disorders and adiponectin was done before chemotherapy and during febrile neutropenia. Patients were followed up until the end of the first hospitalization. Data were analyzed with Statistica software and presented in tables and graphs. Statistical significance was set at p&lt;0.05. Results: During febrile neutropenia, patients with acute leukemia developed insulin resistance (t = - 2.43, p = 0.021), alongside significant decline of total cholesterol (t = 3.59, p = 0.0012), LDL &ndash; cholesterol (t = 3.56, p = 0.0013) and apoA &ndash; I (t = 2.27, p = 0.03). In acute inflammation, metabolic changes in patients with acute leukemia resembled those in the obese with insulin resistance. HOMA-IR values were in positive correlation with fibrinogen (r = 0.59, p &lt; 0.05) whereas apoA-I was in negative correlation to CRP (r = - 0.37, p &lt; 0.05). Patients with higher body mass index and waist circumference had better course and outcome of febrile neutropenia (r = - 0.47, p &lt; 0.05 vs. r = - 0.40, p &lt; 0.05). Patients with lower insulin levels and HDL - cholesterol prior to chemotherapy had a significantly better course of febrile neutropenia (t = -2.38, p = 0.024 vs. t = - 2.87, p = 0.007). Other parameters of insulin sensitivity, metabolic status, and adiponectin did not influence the course and outcome of inflammation significantly. Normal body weight, duration of febrile neutropenia for longer than 7 days, lower MASCC risk index, higher CRP and adiponectin, low Lp(a) in febrile neutropenia and a complicated course od febrile neutropenia were predictors of a worse outcome. Conclusion: Besides known hematological risk factors for complications in febrile neutropenia, anthropometric characteristics, fat mass distribution and disfunction, insulin resistance and metabolic parameters are useful predictors of the course and outcome of febrile neutropenia.</p>
