ABSTRACT

PURPOSE: Mycophenolic acid is one of the most used immunosuppressive drugs in solid organ transplant treatments in the world. Developing a highly sensitive analytical method to analyse the drug and its metabolites in oral fluid and plasma is important to evaluate the possibility of using oral fluid as a biological matrix in therapeutic drug monitoring, instead of plasma. METHOD: The liquid chromatography coupled to mass spectrometry (LC-MS) method was developed and validated for determining mycophenolic acid (MPA) and its glucuronide metabolite (MPAG) in oral fluid and plasma, with both matrices presenting a detection limit of 1 ng/mL for MPA and 5 ng/mL for MPAG. Both analytes were analysed after a simple protein precipitation procedure. Transplanted-kidney samples of oral fluid and blood were collected from 13 patients that were hospitalised and kept at - 80 °C until analyses. RESULTS: The proposed method was linear in the concentration range of 5-500 ng/mL for MPA and 10-500 ng/mL for MPAG, with correlation coefficients (r) between 0.9925 and 0.9973. It was then applied to samples collected from kidney-transplanted patients and used for calculation of pharmacokinetics parameters. CONCLUSION: After comparing plasma and oral fluid concentrations as well as performing a non-compartmental pharmacokinetic analysis of the average curves, it is possible to suggest that oral fluid concentration may be used as an alternative for MPA and MPAG monitoring in kidney transplant patients.

ABSTRACT

INTRODUÇÃO: A higienização das mãos é um importante procedimento para a prevenção de infecções relacionadas à diálise peritoneal. OBJETIVO: Comparar a eficácia de duas técnicas de higienização das mãos na redução do número de unidades formadoras de colônia em pacientes em programa de diálise peritoneal. MATERIAIS E MÉTODO: Ensaio Clínico controlado. Trinta indivíduos submetidos a três coletas da flora microbiológica das mãos, em três momentos distintos: antes e após higienização das mãos com água e sabão glicerinado; após aplicação de álcool-gel etílico glicerinado a 70%. Culturas obtidas da superfície dos dedos das mãos, diretamente em placas de Agar Sangue de Carneiro. RESULTADOS: O crescimento médio nas culturas foi 31, 30 e 12 unidades formadoras de colônia antes da higienização, após a lavagem com água e sabão glicerinado e após a fricção com álcool gel, respectivamente (p < 0, 001). Staphyloccocus epidermidis ou Estafilococo coagulase-negativo foi o germe predominante, presente em 93,7% das placas. CONCLUSÃO: A higienização com álcool gel produziu maior redução no número de unidades formadoras de colônia.


INTRODUCTION: Hand hygiene is an important procedure in preventing peritoneal dialysis-related infections. OBJECTIVE: To compare the effectiveness of two distinct techniques for hand hygiene in reducing the number of colony-forming units in patients on peritoneal dialysis. MATERIALS AND METHOD: Controlled clinical trial. Thirty patients underwent three collections of microbiological flora from the hands in three different instances: before and after hand washing with glycerin soap and water, and after rubbing 70% glycerin gel-alcohol. Cultures were obtained by applying the fingers surface directly on agar-blood plates. RESULTS: Cultures mean growth were 31, 30 e 12 colony-forming units prior to washing, after washing with glycerin soap and water, and following gel-alcohol, respectively (p < 0.001). Staphylococcus epidermidis was the predominant germ in culture, occurring in 93.7% of seeded plates. CONCLUSION: Hand rubbing with gel-alcohol was more effective in reducing the number of colonies recovered than the other methods.

ABSTRACT

INTRODUCTION: Hepatitis B (HB) may progress to cirrhosis and liver carcinoma. Its prevalence is estimated at 3.2 % in hemodialysis (HD) patients. HB vaccine when applied intramuscularly (IM) in end-stage renal disease patients often does not induce appropriate antibody titers. However, there has been suggestion for intradermal (ID) to be a more effective inoculation method. OBJECTIVE: To compare the immune response to IM or ID vaccine administration on HD patients. PATIENTS AND METHODS: Thirty one incident HD patients were randomly assigned alternately to IM or ID vaccine inoculation. Vaccine doses were applied at three monthly intervals, with patients being followed-up for six months. Sixteen patients were assigned to IM (40 mg/dose) and 15 to ID (4 mg/dose) vaccine administration. HB-virus surface antibody titer, hematimetric parameters, serum urea level and Kt/V were monthly evaluated. C-reactive protein, parathormone, ferritin, aminotransferases and albumin serum levels were evaluated before and at the sixth month of the initial inoculation. RESULTS: Urea levels were significantly higher in the ID group (P(1) = 0.031); ferritin levels were higher in the IM (P(2) = 0.037) and C-reactive protein levels tended to be higher in the ID group. An interim evaluation by the Safety Monitoring Committee recommended discontinuing the study as IM vaccination had converted 62.5% of the exposed subjects, while ID inoculation converted only 13.3%. CONCLUSION: As performed, ID applied vaccine was inferior to the IM inoculation. Such result may depend on the inoculated doses or some other factor, such as inflammation.

ABSTRACT

INTRODUÇÃO: A hepatite B pode evoluir para cirrose e hepatocarcinoma. Sua prevalência estimada é de 3,2 por cento em pacientes em hemodiálise (HD). A vacina para hepatite B (HB), quando aplicada por via intramuscular (IM) em pacientes com insuficiência renal crônica fase V, frequentemente não induz produção adequada de anticorpos. A injeção intradérmica (ID) foi sugerida como sendo o método de inoculação mais eficiente. OBJETIVO: Comparar a resposta imune à injeção IM ou ID da vacina em indivíduos em HD. PACIENTES E MÉTODOS: Trinta e um pacientes incidentes em HD foram randomizados alternativamente para vacinação contra HB via IM ou ID. Dezesseis foram designados aleatoriamente para receber vacina IM (40 mg/dose) e 15 ID (4mg /dose). Os níveis de anticorpos de superfície do vírus da hepatite B, parâmetros hematimétricos, ureia sérica, e Kt/V foram avaliados mensalmente. Proteína-C reativa, paratormônio, ferritina, aminotransferases e albumina foram avaliados antes da inoculação inicial e seis meses após a mesma. RESULTADOS: Os níveis de uréia foram maiores no grupo ID (P(1) = 0,031); os níveis de ferritina foram mais elevados no IM (P(2) = 0,037). Houve tendência a aumento nos níveis de proteína C reativa no grupo ID. A avaliação do Comitê de Monitoramento de Segurança dos indivíduos expostos recomendou a suspensão do estudo já que a inoculação por via IM converteu 62,5 por cento e a ID converteu apenas 13,3 por cento dos pacientes expostos. CONCLUSÃO: Com a metodologia utilizada, os resultados da vacina contra HB aplicada por via ID foi inferior à inoculação IM. Tais resultados podem ser decorrentes das doses inoculadas ou de outros fatores, como inflamação.

ABSTRACT

Estudo de corte avaliando efeitos de programa de ensino-aprendizagem sobre o metabolismo e controle de níveis séricos de cálcio (Ca), fósforo (PO4), paratormônio (PTH), produto Ca x PO4, em 33 pacientes estáveis em HD, randomizados para dois grupos: Controle (n=17) e Intervenção (n=16). O grupo Controle recebeu informação sobre acesso vascular: a Intervenção sobre metabolismo de Ca, PO4 e PTH. Mudanças de conhecimento avaliadas por testes pré e pós-classe; adesão à terapia por dosagens laboratoriais seriadas. Não houve mudança significativa de conhecimento em qualquer grupo [Intervenção: 8/17 vs. 14/17 pacientes competentes no pré e pós-teste, respectivamente (P<0.001); Controle: 11/16 vs. 13/16 pacientes competentes, respectivamente (P<0.001)]. Houve redução de PO4 e produto Ca x PO4 entre tempos 0 e 1 em ambos os grupos e entre tempos 1 e 2 no grupo Controle. Concluiu-se que o programa não induziu mudança de conhecimento ou comportamento e que os programas de ensino-aprendizagem para renais crônicos devem ser contínuos.


This cohort study evaluated the effects of an educational program about metabolism and control of serum levels of calcium (Ca), phosphorus (PO4), parathormone (PTH), Ca x PO4 product on 33 stable patients on hemodialysis. Patients were randomized into two groups: control (n=17) and intervention (n=16). The control group received information on vascular access. The intervention group was informed about Ca, PO4 and PTH metabolism. The changes in knowledge were evaluated using tests. Treatment compliance was assessed by serial laboratory tests. No significant change was observed in their knowledge [intervention: 8/17 vs. 14/17 competent patients before and after class, respectively (P<0.001); control: 11/16 vs. 13/16 competent patients, respectively (P<0.001)]. A reduction was observed in PO4 and Ca x PO4 product between time 0 and 1 in both groups and between time 1 and 2 in the control group. The program did not induce changes in knowledge or behavior. In conclusion, chronic renal patients should be offered continuous educational programs.

ABSTRACT

Atherosclerosis, beginning in childhood, is dependent on several risk factors and may be predictive of coronary artery disease in adulthood. The risk factors for subclinical atherosclerosis are similar to those for clinical disease. Carotid intima-media thickness is a measure of subclinical atherosclerosis and a predictor of subsequent vascular events. This study aimed to examine the relationships of carotid intima-media thickness with known risk factors in asymptomatic children. Family history of cardiovascular disease was collected, together with anthropometric, demographic, and clinical data. Body mass index z-scores were calculated. Serum glucose, lipid fractions, fibrinogen, and C-reactive protein were determined. High-resolution ultrasonography was used to assess intima-media thickness. Associations and relationships of risk factors with composite intima-media thickness were explored. The study enrolled 93 children (44 girls) ranging in age from 49 to 169 months. The boys had a thicker intima-media (0.46 +/- 0.06 mm) than the girls (0.43 +/- 0.06 mm; p = 0.028). The unadjusted triglyceride levels were significantly higher in the overweight and obese children (p = 0.010). Body mass index and overweight/obesity were positively related to intima-media thickness (r = 0.259; p = 0.012 and r (s) = 0.230; p = 0.027, respectively), whereas family history of cardiovascular disease was unrelated. Only gender and overweight/obesity were related to intima-media thickness in a multiple linear regression model (R (2) = 0.125; p = 0.002). Male gender and overweight/obesity were associated with increased intima-media thickness, whereas family history of cardiovascular disease was unrelated.

ABSTRACT

Hypokalemic periodic paralysis is a rare life-threatening syndrome, potentially reversible when detected at an early stage. Hypokalemia may also occur in other conditions characterized by muscle weakness. Acute myopathy associated with thyrotoxicosis has been described in Asian populations, although it seldom affects Caucasians or African-Americans. It can be difficult to recognize in western populations. Acute recurrent episodes of flaccid paralysis, symmetrically affecting the proximal muscles of the lower limbs, either following strenuous physical activity or carbohydrate overindulgence, is the usual presentation. Hypokalemia seems to result from transcellular shifts of potassium rather than losses. A case of thyrotoxic hypokalemic periodic paralysis occurring in a young Caucasian male diagnosed with Graves' disease is reported.

ABSTRACT

BACKGROUND: This study was aimed at examining the effects of radiocontrast agents on selected membrane transport functions. METHODS: The effect of diatrizoate sodium (DS), diatrizoate meglumine (DM), and diatrizoate compound (DC) on Na+/K+ pump activity and number, L-arginine, and choline transports were evaluated in erythrocytes of normal individuals and patients undergoing cardiac catheterization. RESULTS: Norrmal individuals' erythrocytes potassium influxes were 1.50+/-0.35, 1.32+/-0.37, 1.28+/-0.30, and 1.01+/-0.25 mmol/L cell/h in control, DS, DM, and DC groups, respectively (P=0.004; DC vs. control). Patients exposure to Hypaque M-76 significantly diminished Na+/K+ pump activity (1.40+/-0.36 before, vs. 1.27+/-0.40 mmol/L cell/h after; P=0.039). The number of Na+/K+ pumps was reduced (156+/-36 vs. 143+/-34 pumps/erythrocyte; P=0.015) in presence of DS. L-arginine and choline transports changed only at high radiocontrast concentrations. CONCLUSION: Selective changes in erythrocytes membrane transport function take place on exposure to radiocontrasts.

ABSTRACT

A hipertensão arterial no pós-operatório de cirurgia cardíaca ocorre em até 80 dos pacientes. A hipótese de que esta complicação estaria relacionada com função miocárdica preservada foi sugerida após relatos observacionais. Sabe-se que a hipertrofia venticular esquerda pode apresentar-se com função sistólica supranormal. Este estudo tem como objetivo determinar a associação de condições pré-operatórias e eventos cirúrgicos com o desenvolvimento de hipertensão, após cirurgia cardíaca. No hospital São Lucas da PUCRS entre janeiro de 1996 e abril de 1997 foram avaliados 227 pacientes submetidos a cirurgia de revascularização miocárdica e verificado no pré operatório a função ventrícula e a presença de HVE através do Ecocardiograma. A incidência de hipertensão no pós-operatório foi de 52. A fração de ejeção média foi de 64 nos pacientes que desenvolveram hipertensão contra 46 naqueles que não desesnvolveram (P < 0,05). Na análise de regressão logística multivariada, apresentaram-se como preditores independentes as seguintes variáveis: Fração de ejeção > 40 e Hipertrofia ventricular esquerda. A fração de ejeção com cortes em 50 e 60 também mostrou correlação positiva para hipertensão. A maior probabilidade de hipertensão no pós-operatório foi a associação de hipertrofia ventricular esquerda e FE > 60, mostrando uma probabilidade de 0,93. Os dados sugerem que hipertensão no pós-operatório está relacionada a função ventricular prevervada e hipertrofia ventricular esquerda.

ABSTRACT

INTRODUÇÃO: Os índices preditivos de desfecho disponíveis, aplicados a pacientes com insuficiência renal aguda (IRA), podem se tornar imprecisos quando transportados para outras populações de pacientes ou sob diferentes condições de tratamento intensivo. A finalidade do presente trabalho foi avaliar o desempenho de dois índices conhecidos - um geral e outro específico para IRA - e compará-los a outro, localmente desenvolvido. PACIENTES E MÉTODO: Uma amostra de 280 pacientes em IRA e que necessitaram diálise foi avaliada. Fatores causais, disfunções orgânicas, variáveis clínicas e escores prognósticos foram avaliados. Parâmetros que foram selecionados por análise bivariada foram submetidos a modelos de análise de regressão multivariada, e um índice local foi desenvolvido. Na determinação da capacidade de discriminação e para avaliar a calibração do índice usou-se curvas Receiver Operating Characteristics (ROC), o teste Goodness-of Fit e análise de regressão linear. Para validar o modelo logístico foi usada a técnica de Bootstrapping. O desfecho foi mortalidade hospitalar. RESULTADOS: A mortalidade da amostra foi 85 por cento (238 pacientes) e o número médio de disfunções orgânicas 3.7 (ñ 1,3). O risco estimado de morte pelo índice local, pelo geral e pelo específico para IRA foi 0,85 (IC 95 por cento: 0,83-0,87; P = 1,00), 0,47 (IC 95 por cento: 0,45-0,49; P = 0,001) e 0,66 (IC 95 por cento: 0,64-0,68; P < 0,001), e; as áreas sob a ...(au)

ABSTRACT

Foram analisados os prontuários de 35 pacientes com diagnóstico clínico de Lupus Eritematoso Sistêmico, dos quais dois foram excluídos. Material histológico de 43 biópsias renais, das quais seis foram desprezadas por inadequaçäo do material, foram examinadas e classificadas, independentemente, por dois observadores. Lesäo Proliferativa Difusa (Classe IV da Classificaçäo da OMS) foi a de maior prevalência no material histológico examinado. Este grupo apresentou os maiores índices de atividade e cronicidade, bem como as mais severas manifestaçöes clínicas. Näo se detectou correlaçäo entre os índices de atividade e cronicidade com a evoluçäo clínica. O quadro histológico pode sofrer modificaçöes ao longo do tempo. A sobrevida destes pacientes, em Hemodiálise Crônica, näo parece ser diferente da de outros grupos de urêmicos

ABSTRACT

Diálise Peritoneal Ambulatorial Contínua (CAPD) vem sendo usada para tratamento de pacientes com Insuficiência Renal Crônica há cerca de dez anos. Há três anos foi implantado no Hospital Säo Lucas da PUCRS como método alternativo à Hemodiálise. O tratamento foi aplicado a dezoito pacientes urêmicos crônicos, com 22 catéteres de silástico modelo Tenck-hoff. Durante dois anos foi observada a evoluçäo e eventuais complicaçöes. Analisamos a incidência das complicaçöes, comparando-se à de outros centros de diálise peritoneal. O índice de peritonites foi semelhante ao da literatura (1,52 peritonites/paciente-ano), assim como a freqüência de hospitalizaçöes. Houve mais infecçöes de trajeto e retirada de catéteres tardiamente. O método parece ser suficientemente bom para garantir sua aplicaçäo a um grupo selecionado de pacientes urêmicos crônicos
