Plasmapheresis as an Adjuvant Therapy for Hypertriglyceridemia-Induced PancreatitisIskandar, Said B., Olive, Kenneth E. 01 January 2004 (has links)
Hypertriglyceridemia is an uncommon cause of pancreatitis. A serum triglyceride level of more then 1000 to 2000 mg/dL is an identifiable risk factor. Interestingly, serum pancreatic enzyme levels may be normal or only minimally elevated in such cases. The reduction of triglyceride level to below 1000 mg/dL effectively prevents further episodes of pancreatitis. The mainstay of treatment for the hypertriglyceridemia associated with pancreatitis includes dietary restriction of fat and administration of lipid-lowering agents. It is thought that within 24 to 48 hours of the onset of pancreatitis, in the majority of patients, triglyceride levels fall rapidly as a result of fasting status, as the absorption of chylomicrons to the blood is cut off. Experiences with plasmapheresis are limited. We report a case of hypertriglyceridemic necrotizing pancreatitis with mildly elevated amylase and lipase, treated successfully with plasmapheresis.

Efetividade da plasmaférese no pré-operatório de timectomia em pacientes com miastenia gravis - revisão sistemática e metanáliseReis, Tarcísio Albertin dos January 2018 (has links)
Orientador: Daniele Cristina Cataneo / Resumo: Objetivo: avaliar, por meio de uma revisão sistemática, a efetividade da plasmaférese no pré-operatório de timectomia em pacientes com miastenia gravis (MG). Métodos: Foram pesquisadas as bases Medline, Embase, Lilacs, Scopus e Central para busca de estudos experimentais e observacionais que avaliaram a plasmaférese no pré-operatório de timectomia em pacientes com MG. Grupo com plasmaférese (PPG) e grupo sem plasmaférese (NPPG). Os desfechos avaliados foram: crise miastênica, mortalidade, pneumonia, sangramento, uso de ventilação mecânica, tempo de permanência hospitalar e em unidade de terapia intensiva (UTI). Utilizou-se para metanálise o software RevMan 5.3 fornecido pela Colaboração Cochrane. Resultados: O número total de pacientes avaliados em seis estudos selecionados foi de 323 (143 PPG e 180 NPPG). A plasmaférese pré-operatória não diminuiu a crise miastênica (RR 0,36, IC 95% 0,08 a 1,66; I2 = 44%; 5 estudos, 243 pacientes). Também não houve alteração na mortalidade (RR 0,7, IC 95% 0,11 a 4,62; I² = 0%; 3 estudos, 172 pacientes) ou taxa de pneumonia (RR 0,28, IC 95% 0,07 a 1,09; I2 = 27%; 5 estudos, 272 pacientes). Os pacientes do grupo NPPG sangraram menos em comparação com o grupo PPG (diferença média 34,34 ml, IC 95% 24,93 a 43,75; I² = 0%). Foi avaliada a necessidade de ventilação mecânica em três estudos (213 pacientes) e a permanência hospitalar e em UTI em dois (121 pacientes), que não foram adequados para realizar a metanálise devido à alta heterogeneidade nes...

Methods: Medline, Embase, Lilacs, Scopus and Central databases were searched for experimental and observational studies that evaluated plasmapheresis in the preoperative period of thymectomy in MG patients. Plasmapheresis group (PPG) and without plasmapheresis group (NPPG). The outcomes evaluated were: myasthenic crisis, mortality, pneumonia, bleeding, use of mechanical ventilation, length of hospital stay and intensive care unit (ICU) stay. The RevMan 5.3 software provided by the Cochrane Collaboration was used for meta-analysis. Results: The total number of patients evaluated in six included studies was 323 (143 PPG and 180 NPPG). Preoperative plasmapheresis did not decrease the myasthenic crisis (RR 0.36, 95% CI 0.08 to 1.66, I2 = 44 %; 5 studies, 243 patients). There was also no change in mortality (RR 0.7, 95% CI 0.11 to 4.62, I² = 0%; 3 studies, 172 patients) or pneumonia (RR 0.28, 95% CI 07 to 1.09, I2 = 27%; 5 studies 272 patients). Patients in the NPPG group bleed less in comparison to the PPG group (mean difference 34.34 ml, 95% CI 24.93 to 43.75, I² = 0%).

A análise dos subgrupos mostrou que a realização da plasmaférese no pré-operatório de pacientes com doença grave (Osserman III e IV) diminuiu a crise miastênica no pós-operatório (RR 0,12, IC 95% 0,02 a 0,65; I² = 63%). Conclusão: A plasmaférese pode reduzir as crises miastênicas pós-operatória em pacientes com doença grave (Osserman III e IV), mas pode produzir pouca ou nenhuma diferença em pacientes com doença de expressão clínica leve (Osserman II). / Objective: to evaluate, through a systematic review, the efficacy of plasmapheresis in the preoperative thymectomy in patients with myasthenia gravis (MG).

Subgroup analysis showed that the preoperative plasmapheresis performed in patients with severe disease (Osserman III and IV) decreased the myasthenic crisis postoperatively (RR 0.12, 95% CI 0.02 to 0.65, I² = 63 %). Conclusion: Plasmapheresis may reduce postoperative myasthenic crisis in patients with severe disease (Osserman III and IV), but may produce little or no difference in patients with mild clinical expression disease (Osserman II).

Influência do uso da plasmaferese sobre o tempo de recuperação de caprinos doadores de sangue ou plasma / Influence of the plasmapheresis uses in the recovery time of blood or plasma donor goatsSantos, Rogerio Batista dos 19 December 2005 (has links)
O objetivo desta pesquisa foi determinar a influência do uso da plasmaferese sobre o tempo de recuperação clínica e hematológica de caprinos doadores de sangue total ou plasma. Para tanto, foram utilizados 20 caprinos adultos e clinicamente sadios, distribuídos por dois grupos de 10 animais cada, a saber: grupo controle (de animais doadores de sangue total não tratados) e grupo experimental (de animais doadores que foram tratados através da plasmaferese). Os caprinos foram selecionados e monitorados através de exames físicos (funções vitais) e complementares (hemograma, proteínas totais, albumina, globulinas, relação A:G, uréia, creatinina e hemoglobina livre no plasma) realizados nos seguintes momentos: imediatamente antes e após a doação de sangue: 12 h, 24h, 72h, 120h, 360h, 480h, e 720 horas após os procedimentos. Os resultados foram analisados com comparações dentro e entre os dois grupos nos diferentes momentos do estudo. As observações clínicas efetuadas durante o período de até trinta dias após a doação de 20% do volume sangüíneo total, com ou sem a realização da plasmaferese nos animais dos grupos estudados não sofreram variações influenciadas por esses procedimentos. Observou-se significativa variação dos componentes do eritrograma, tendo o grupo experimental apresentado as melhores taxas de recuperação em função do tempo. Com base nos resultados obtidos, a aplicação da técnica da plasmaferese em caprinos mostrou-se eficiente como recurso para a otimização do tempo de recuperação dos valores do hemograma de animais doadores de plasma, não determinando hemólise durante o seu procedimento / The objective of this study was to determine the influence of plasmapheresis on clinical and haematological recovery time of whole blood or plasma donor goats. For this, 20 clinically healthy adult goats were divided into two groups of ten animals each: control group (not-treated whole blood donor animals), and experimental group (donor animals which were treated with plasmapheresis). Goats were selected and evaluated through physical examination (vital functions) and complementary tests (haemogram, total proteins, albumin, globulin, albumin:globulin ratio, urea nitrogen, creatinine, and plasma free haemoglobin), carried out at the following moments: immediately before and after blood donation, 12, 24, 72, 120, 360, 480, and 720 hours after the procedures. Results were analysed comparing animals in and between both groups (at differents moments of the study). The clinical observations made during the period of thirty days after donation of 20% of total blood volume, with or without plasmapheresis in the animals of studied groups, were not influenced by these procedures. The results revealed significant variation of eritrogram components, showing the experimental group to have better recovery rates according to time. Based on the results obtained in the present study, plasmapheresis technique application in goats showed to be efficient as a resource to optimize recovery time of haemogram values of plasma donor animals, and did not cause hemolisis during its procedure

(thesis): Basis: This diploma thesis follows the bachelor thesis that concentrates on the eating habits and water intake of blood plasma donors before plasmapheresis. Goals: The research had four goals: 1) explore to what extent does providing of the educational material influence the awareness of blood plasma donors. 2) To map subjective state of health and lifestyle of plasma donors regarding their physical activity, healthy, regular, varied diet, smoking and sleep schedule. 3) To explore the knowledge of regime measures and risk behaviour before donating blood plasma. To evaluate donors' eating habits and water intake before plasmapheresis and reveal potential deficiencies. 4) Evaluate the knowledge of a given problem with those respondents who were provided with educational material in comparison with those respondents who got no educational material. Methods: An educational material was created regarding regime measures of blood plasma donors. This educational material served as the basis for standardized anonymous questionnaire. Maintaining the ethical principles and with the ethical committee's approval, overall data of 40 respondents frequenting Haematology Department and blood transfusion of the Military University Hospital Prague. The sample consisted of two groups of randomly selected...
