Allocation to highly sensitized patients based on acceptable mismatches results in low rejection rates comparable to non-sensitized patients

Whereas regular allocation avoids unacceptable mismatches on the donor organ, allocation to highly sensitized patients within the Eurotransplant Acceptable Mismatch (AM) program is based on the patient's HLA phenotype plus acceptable antigens. These are HLA antigens to which the patient never made antibodies, determined by extensive laboratory testing. AM patients have superior long-term graft survival compared to highly sensitized patients in regular allocation. Here, we questioned whether the AM program also results in lower rejection rates. From the PROCARE cohort, consisting of all Dutch kidney transplants 1995-2005, we selected deceased donor single transplants with minimum one HLA mismatch and determined the cumulative 6-month rejection incidence for patients in AM or regular allocation. Additionally, we determined the effect of minimal matching criteria of one HLA-B plus one HLA-DR, or two HLA-DR antigens on rejection incidence. AM patients showed significantly lower rejection rates than highly immunized patients in regular allocation, comparable to non-sensitized patients, independent of other risk factors for rejection. Contrasting to highly sensitized patients in regular allocation, minimal matching criteria did not affect rejection rates in AM patients. Allocation based on acceptable antigens leads to relatively low risk transplants for highly sensitized patients with rejection rates similar to non-immunized individuals.

Influence of personalized extended interval dosing on the natalizumab wearing-off effect - a sub-study of the NEXT-MS trial

Background and objectives: Wearing-off symptoms during natalizumab treatment in multiple sclerosis are characterized by an increase of MS-related symptoms prior to natalizumab administration. The influence of extended interval dosing (EID) on wearing-off symptoms are important to consider, as this might cause hesitancy in initiating or continuing EID. Methods: Participants of the NEXT-MS trial, in which treatment intervals are adjusted based on drug concentrations, were divided into two groups: an extended group containing participants with at least one week of additional interval extension, and a group with a fixed interval during the trial (range 4–7 weeks). Changes in the occurrence, frequency, onset, and severity of wearing-off symptoms were evaluated. Results: 255 participants were included (extended group n = 171, fixed group n = 84). The odds on occurrence of wearing-off symptoms in the extended group did not increase after extending the treatment interval. Additional analyses for frequency, onset, and severity of wearing-off symptoms showed no changes over time. Mean decrease in natalizumab drug concentration did not influence the frequency of wearing-off symptoms. Discussion: Wearing-off symptoms were not reinforced by further extending the natalizumab interval. Wearing-off symptoms might increase in a minority of patients after EID, although our data support the view that wearing-off symptoms appear to be unrelated to the decrease in natalizumab trough drug concentrations.</p

Orientador: Ivan Santa MariaMonografia (Especialização) - Universidade Federal do Paraná,Setor de Ciências Sociais Aplicadas, Departamento de Contabilidade, Curso de Especialização em Administração PolicialResumo: O presente trabalho monográfico abordou o problema da aplicabilidade de policiais-militares em atividades consideradas meio na Organização, sendo que os mesmos poderiam ser substituídos por deficientes físicos em algumas funções básicas, como telefonista, recepcionista, digitador e outros, redundando num maior emprego de policiaismilitares nas ruas. Para tanto, buscou primeiramente retratar a realidade na PMPR; caracterizar atividades de cunho civil e de cunho militar na atividade meio; além de onde e como aplicar a pessoa portadora de deficiência física. Na parte do desenvolvimento, foram abordadas conceituações básicas, como atividade Policial Militar, atividades-meio e atividades-fim da Polícia Militar, cunho civil e militar na atividade-meio. Na seqüência, abordaram-se aspectos da pessoa portadora de deficiência, sendo navegado em assuntos a respeito da antigüidade, do renascimento, a política demográfica, deficiência em si, Programa Nacional de Direitos Humanos, a realidade social do deficiente e sua situação atual. Tratou-se também dos deficientes físicos e a Polícia Militar, em que buscou-se evidenciar o que existe em legislação peculiar e cargos privativos de militares. Quanto aos direitos dos deficientes, relatou-se a respeito dos tratados internacionais e a legislação brasileira. Ainda no capítulo referente ao desenvolvimento retratou-se a respeito do PSAV - Prestador de Serviço Auxiliar Voluntário (Deficientes Físicos); APR - Associação Paranaense de Reabilitação; ADFP -Associação dos Deficientes Físicos do Paraná; empresas que abrem caminhos para deficientes; uma importante matéria veiculada na Gazeta do Povo com o título "700 Deficientes podem Perder o Emprego", postura esta defendida pelo Estado como sendo o serviço prestado de grande importância econômica e social. Um capítulo tratou sobre a presença de pessoal civil na Polícia Militar, com seus fundamentos legais e doutrinários. Chegou-se ao final do desenvolvimento retratando como seria uma possível implantação da alocação de deficientes físicos em certas atividades-meio da Polícia Militar do Paraná Finalizou o presente estudo tratando das considerações finais, em que algumas propostas foram colocadas, ressaltando-se a importância de primeiramente serem readequadas as instalações físicas das Unidades Policiais-Militares para o ideal recebimento destes funcionário

The presence of donor-specific anti-HLA antibodies (DSAs) is associated with increased risk of graft failure after kidney transplant. We hypothesized that DSAs against HLA class I, class II, or both classes indicate a different risk for graft loss between deceased and living donor transplant. In this study, we investigated the impact of pretransplant DSAs, by using single antigen bead assays, on long-term graft survival in 3237 deceased and 1487 living donor kidney transplants with a negative complement-dependent crossmatch. In living donor transplants, we found a limited effect on graft survival of DSAs against class I or II antigens after transplant. Class I and II DSAs combined resulted in decreased 10-year graft survival (84% to 75%). In contrast, after deceased donor transplant, patients with class I or class II DSAs had a 10-year graft survival of 59% and 60%, respectively, both significantly lower than the survival for patients without DSAs (76%). The combination of class I and II DSAs resulted in a 10-year survival of 54% in deceased donor transplants. In conclusion, class I and II DSAs are a clear risk factor for graft loss in deceased donor transplants, while in living donor transplants, class I and II DSAs seem to be associated with an increased risk for graft failure, but this could not be assessed due to their low prevalence

Allocation to highly sensitized patients based on acceptable mismatches results in low rejection rates comparable to nonsensitized patients

Whereas regular allocation avoids unacceptable mismatches on the donor organ, allocation to highly sensitized patients within the Eurotransplant Acceptable Mismatch (AM) program is based on the patient\'s HLA phenotype plus acceptable antigens. These are HLA antigens to which the patient never made antibodies, as determined by extensive laboratory testing. AM patients have superior long-term graft survival compared with highly sensitized patients in regular allocation. Here, we questioned whether the AM program also results in lower rejection rates. From the PROCARE cohort, consisting of all Dutch kidney transplants in 1995-2005, we selected deceased donor single transplants with a minimum of 1 HLA mismatch and determined the cumulative 6-month rejection incidence for patients in AM or regular allocation. Additionally, we determined the effect of minimal matching criteria of 1 HLA-B plus 1 HLA-DR, or 2 HLA-DR antigens on rejection incidence. AM patients showed significantly lower rejection rates than highly immunized patients in regular allocation, comparable to nonsensitized patients, independent of other risk factors for rejection. In contrast to highly sensitized patients in regular allocation, minimal matching criteria did not affect rejection rates in AM patients. Allocation based on acceptable antigens leads to relatively low-risk transplants for highly sensitized patients with rejection rates similar to those of nonimmunized individuals

Evaluation of the treatment of patients with abdominal complaints at the first aid department of a city hospital, where patients were treated by emergency doctors (EMD) in combination with specialists. Retrospective, descriptive. Onze Lieve Vrouwe Gasthuis, first aid department, Amsterdam, the Netherlands. Data were collected on diagnosis, treatment and course in 3235 patients with abdominal complaints seen at the first aid department in 1997. Non-referred patients were treated by EMD who if necessary consulted a specialist. Referred patients were seen by specialists. Of the 2931 patients who visited the first aid department once, 1975 patients (67%) were seen after self-referral. Of this group, 1557 patients (79%) were treated by the EMD alone and could be sent to the general practitioner (GP) without consulting a specialist. These accounted for 53% of the 2931 patients with abdominal complaints. The EMD used fewer additional tests than the specialist. Of the patients, 91% could be treated conservatively, only 9% were operated. Fifty-three patients died. Analysis of the group of 304 patients who visited the first aid department more than once in the year of study, showed that in 28 cases the diagnosis was missed (in 17 cases by the EMD and in 11 by the specialist). Of this group 23 had to be operated upon. The organisation of a first aid department like that in the OLVG, with EMDs and specialists, appeared efficient; the rates of morbidity, mortality and missed diagnoses are acceptable. With relatively few additional tests, the EMD appeared to be able to differentiate between GP care and hospital car
