Full textResumo: O sistema de qualidade é de suma importância em laboratórios clínicos para avaliação de processos analíticos de maneira que os resultados liberados sejam verdadeiros. Para a metodologia de imunofenotipagem celular por citometria de fluxo as amostras devem ser frescas e os exames realizados preferencialmente dentro de 48 horas. É relevante utilizar amostras de controle de qualidade internos (CQI) padronizadas, de modo que possam ser repetidas rotineiramente, como referencial de qualidade. No Brasil, poucos serviços comercializam amostras preservadas para uso como CQI. Deste modo, a padronização in house com validação de processo para obtenção de amostras que possam ser utilizadas para esta finalidade é relevante. O objetivo deste trabalho foi desenvolver controle de qualidade interno para as rotinas de quantificação de células progenitoras hematopoéticas (CPH), utilizando solução preservante e avaliar a reprodutibilidade e estabilidade ao longo do tempo. Foram preparadas soluções preservantes contendo diferentes concentrações de anticoagulantes e fixadores, e destas, foi selecionada uma composição, originalmente padronizada neste estudo. Foram utilizados 5mL de sangue periférico, sendo este acrescido da solução a ser testada. Imediatamente, realizou-se a quantificação das populações de CPH em tubo Trucount®, usando anti-CD45, anti-CD34 e 7-AAD, conforme indicado pelo fabricante. A leitura foi realizada em citômetro de fluxo modelo FACSCalibur®-BD, para obtenção dos valores abs... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The quality system is of paramount importance in clinical laboratories for evaluating analytical processes in order to consider true the released results. The samples must be performed fresh preferably within 48 hours for the cell immunophenotyping methodology by flow cytometry. It is relevant to use standardized internal quality control (IQC) samples, thus they could be repeated routinely, as a quality benchmark. In Brazil, only a few services commercialize preserved samples for use as IQC. Therefore, it is relevant to use in-house standardization with process validation to obtain samples that can be used for this purpose. The objective of this work was to develop an IQC for a daily routine quantification of hematopoietic stem cells (HSCs) by using a preservative solution and to evaluate the reproducibility and stability over time. Preservative solutions containing different concentrations of anticoagulants and fixatives were prepared, and from these, a composition was selected, which was previously originally standardized in this study. 5mL of peripheral blood were used, which was added to the solution to be tested. The HSCs populations were immediately quantified in a Trucount® tube, using anti-CD45, anti-CD34 and 7-AAD, as indicated by the manufacturer. The reading was performed in a flow cytometer model FACSCalibur®-BD in order to obtain the absolute values of HSCs on day zero, 7, 21, 35 and 49. During this period, the samples were kept refrigerated (2 to 8ºC). The value... (Complete abstract click electronic access below)

Resumo: As células progenitoras endoteliais (EPCs) estão envolvidas em neovasculogênese e na manutenção da homeostase vascular, sua deficiência pode ter papel na patogênese da hipertensão. Este estudo teve como objetivo analisar o perfil de expressão das EPCs circulantes e diferentes fatores de risco cardiovascular em mulheres hipertensas, na pré-menopausa, em comparação com mulheres normotensas saudáveis. Realizou-se um estudo caso-controle com 45 mulheres voluntárias, faixa etária de 30 a 50 anos (41 ± 6) no Ambulatório do Pronto Socorro Cardiológico de Pernambuco. As EPCs definidas como CD45-/CD34+/KDR+ foram coletadas em sangue venoso periférico e analisadas por citometria de fluxo. As mulheres foram classificadas como controles (CT) saudáveis normotensas com PAS (pressão arterial sistólica) < 130 mmHg e PAD (pressão arterial diastólica) < 85 mmHg (n=15), com hipertensão primária: a) Leve (HL) PAS=140-159mm Hg e PAD=90-99 mmHg (n=15) e b) Severa (HS) PAS > 180 mmHg e PAD > 110 mmHg (n=15). Os grupos foram entrevistados quanto aos hábitos de fumo, prática de exercícios físicos e Índice de Massa Corporal (IMC), sendo aferido o nível da PA em repouso. Realizou-se análise nos prontuários dos resultados dos exames séricos de colesterol total, lipoproteínas de alta densidade-colesterol (HDL-c), lipoproteínas de baixa densidade-colesterol (LDL-c), triglicerídeos e glicemia de jejum, no mês da coleta das amostras sanguíneas. Os resultados comprovaram redução significativa ao número de EPCs no HL (74%) e HS (88%) versus CT; e redução de 67% no HS versus HL, evidenciando relação inversa entre o número de células e o estágio da hipertensão. O grupo HS apresentou aumento de 49% de células CD45+ demonstrando padrão inflamatório e redução de 61% de CD45-/CD34+. Quanto aos níveis séricos verificou-se: HDL-c [HL (52±7); HS (48±5)]; LDL-c [HL (130±8); HS (143±15)]; triglicerídeos [HL (138±19); HS(153 ±40)]; glicemia de jejum [HL(95±7);HS(121±39)] e IMC [HL(31±4);HS(29±3)]; revelando que 67% das mulheres com hipertensão severa apresentavam síndrome metabólica (SM). O desenvolvimento da hipertensão e da SM foi diretamente correlacionado com a diminuição das EPCs. Portanto, a contagem de EPCs pode ser considerada um marcador biológico adequado para indicar a gravidade do estado hipertensivo em mulheres
Abstract: Endothelial progenitor cells (EPCs) are involved in neovasculogenesis and maintenance of vascular homeostasis and their impairment may have a role in the pathogenesis of hypertension. This study aimed analyzes the expression profile of circulating EPCs and different cardiovascular risk factors in hypertensive premenopausal women compared with healthy normotensive women. A case-control study was conducted enrolling 45 women volunteers, aged from 30- 50 years (41 ± 6) in Ambulatory of the Cardiologic Emergency Hospital of Pernambuco. EPCs numbers were determined by flow cytometry in peripheral blood as the CD45-/CD34+/KDR+ cells. The women were classified as healthy normotensive controls (CT) with SBP (systolic blood pressure) <130 mmHg and DBP (diastolic blood pressure) < 85 mmHg (n=15), and with essential hypertension; a) mild (MH), SBP=140-159 mmHg and DBP=90-99 mmHg (n=15); and b) severe (SH), SBP>180 mmHg and DBP>110 mmHg (n=15). The group were interviewed regarding smoking habits, physical exercise and body mass index (BMI), and measured the level of blood pressure at quiescent. An analysis in records of test results cholesterol, high density lipoprotein-cholesterol (HDL-c), low density lipoprotein-cholesterol (LDL-c), triglycerides and fasting glucose in the month of collection of blood samples. The results found a significant reduction in circulating EPCs numbers in MH (74%) and SH (88%) when compared to the CT and reduction of 67% in SH when compared to MH, an inverse relationship between the number of cells and the stage of hypertension. SH group showed an increase of 49% CD45+ cells demonstrating inflammation and reduction of 61% CD45-/ CD34+ cells. Regarding the biochemical serum was found: HDL-c [MH (52±7); SH (48±5)]; LDL-c [MH (130±8); SH (143±15)]; triglycerides [MH (138±19); SH (153±40)]; fasting glucose [MH (95±7); SH (121±39)] and BMI [MH (31±4); SH (29±3)]; revealing that 67% of women with severe hypertension had metabolic syndrome (MS). Development of hypertension and the parameters related to MS are directly correlated with a decrease of circulating EPCs. Therefore, the EPCs counting may be considered a suitable biological marker to follow up the evolution of the hypertensive state in women
