The Impact

Abstract Abstract 869 Polymorphisms in drug metabolizing enzymes are known to contribute to inter-individual differences in the pharmacokinetics (PK) of the two most commonly used drugs for conditioning for hematopoietic stem cell transplantation (HSCT), busulfan (Bu) and cyclophosphamide (Cy) and their metabolites in plasma. We have previously reported the impact of CYP genes on the PK of Cy, [Blood (ASH Annual Meeting Abstracts), Nov 2004; 104: 99] and the influence of Cy PK on transplant outcome [Blood (ASH Annual Meeting Abstracts), Nov 2004; 104: 1820]. We have now extended this study to evaluate a total of 19 polymorphisms in 11 genes that are known to be involved in the metabolism of Bu and Cy. 180 of the 276 patients with thalassemia major who underwent HSCT between March 1991 and Dec 2008 and for who genomic DNA was available were included in the study. The following polymorphisms were screened using PCR followed by RFLP and/ or gel electrophoresis: GSTA1*B, GSTM1 and GSTT1 deletion, GSTP1*B, CYP2B6*2, *3, *4, *5 and *6, CYP2C9*2, *3 and *4, CYP2C19*2, *3, CYP3A4*1B, CYP3A5*3, *6 and ALDH1A1*2 and ALDH3A1*2. Polymorphism frequencies were associated with regimen related toxicities, other transplant related complications using Fischer's Exact test and Cox-proportional hazard's model.. Significant associations are shown in the Table. On univariate analysis, CYP2B6*4 variant genotype was associated with incidence of hemorrhagic cystitis (HC); CYP2C9*3 variant genotype was associated with the severity of HC; CYP2C19*3 and 2C9*2 genotypes were associated with overall and even-free survival (OS and EFS) and CYP2C9*2 and CYP2C9*3 genotype was associated with transplant related mortality (TRM). Multivariate analyses performed adjusting for known clinical risk factors still showed these genotypes to be significantly associated with outcome parameters. Variant genotypes of polymorphisms that result in decreased metabolism of Cy are protective against regimen related toxicities while these polymorphisms were risk factors for EFS and OS in the present study. This is the first report on the influence of common GST, CYP and ALDH polymorphisms on outcome of HSCT in patients with thalassaemia major. Screening for these polymorphisms in patients with beta thalassaemia undergoing HSCT can help identify patients at higher risk of complications.Table:EndpointGenotypeRelative risk (95% CI)P- value HCCYP2B6*4 variant0.3 (0.13-0.889)0.028 HC grade 1 vs. HC grade 2-4CYP2C9*3 variant0.2 (0.073-0.962)0.043 TRM2C9*2 variant2.7 (1.08-6.77)0.034 2C9*3 variant2.3 (1.0-5.7)0.049 OS and EFS2C19*3 variant3.3 (1.2-9.3)0.018 2C9*2 variant1.3 (0.93-2.03)0.070 Disclosures: No relevant conflicts of interest to declare.

Probability Of Death

SummaryA total of 333 patients with stable intermittent claudication at recruitment were followed up for 6 years to determine risk factors associated with subsequent mortality. Cardiovascular diseases were the underlying cause of death in 78% of the 114 patients who died. The strongest independent predictor of death during the follow-up period was the plasma fibrinogen level, an increase of 1 g/l being associated with a nearly two-fold increase in the probability of death within the next 6 years. Age, low ankle/brachial pressure index and a past history of myocardial infarction also increased the probability of death during the study period. The plasma fibrinogen level is a valuable index of those patients with stable intermittent claudication at high risk of early mortality. The results also provide further evidence for the involvement of fibrinogen in the pathogenesis of arterial disease.

<strong>Objective:</strong> We aimed to evaluate the risk factors associated with acute renal failure in patients who underwent coronary artery bypass surgery.<br /><strong>Methods:</strong> One hundred and six patients who developed renal failure after coronary artery bypass grafting (CABG) constituted the study group (RF group), while 110 patients who did not develop renal failure served as a control group <br />(C group). In addition, the RF group was divided into two subgroups: patients that were treated with conservative methods without the need for hemodialysis (NH group) and patients that required hemodialysis (HR group). Risk factors associated with renal failure were investigated.<br /><strong>Results:</strong> Among the 106 patients that developed renal failure (RF), 80 patients were treated with conservative methods without any need for hemodialysis (NH group); while <br />26 patients required hemodialysis in the postoperative period (HR group). The multivariate analysis showed that diabetes mellitus and the postoperative use of positive inotropes and adrenaline were significant risk factors associated with development of renal failure. In addition, carotid stenosis and postoperative use of adrenaline were found to be significant risk factors associated with hemodialysis-dependent renal failure (P &lt; .05). The mortality in the RF group was determined as 13.2%, while the mortality rate in patients who did not require hemodialysis and those who required hemodialysis was 6.2% and 34%, respectively.<br /><strong>Conclusion:</strong> Renal failure requiring hemodialysis after CABG often results in high morbidity and mortality. Factors affecting microcirculation and atherosclerosis, like diabetes mellitus, carotid artery stenosis, and postoperative vasopressor use remain the major risk factors for the development of renal failure.<br /><br />

Objetivo: Ainda não está claro quais são os fatores de risco para a esquizofrenia resistente ao tratamento (ERT) em primeiro episódio psicótico (PEP). O objetivo deste trabalho é investigar indicadores de risco para ERT em PEP. Métodos: Foram selecionados 53 pacientes em primeiro episódio psicótico, com diagnóstico de esquizofrenia, que deram entrada à enfermaria de psiquiatria do Hospital das Clínicas Luzia de Pinho Melo entre 2011 e 2015. Ao ser admitido na enfermaria, o paciente era avaliado com a Escala de Sintomas para as Síndromes Positiva e Negativa (Positive and Negative Syndrome Scale – PANSS) e recebia tratamento inicial por 4 semanas. Caso sua resposta fosse inferior a 40% de redução na PANSS, o antipsicótico era trocado, e as escalas eram aplicadas novamente após mais 4 semanas. Após a falha com dois antipsicóticos, em doses plenas, por 4 semanas cada, a clozapina era introduzida, e o paciente era considerado ERT. Uma regressão logística foi aplicada onde sexo, idade de início, tempo de doença não tratada, uso de substâncias, avaliação global do funcionamento inicial e PANSS inicial total foram inseridos como variáveis independentes, e ERT foi inserida como variável dependente. Resultados: Tempo de doença não tratada apresentou significância de p = 0,038 e Exp (B) = 4,29, enquanto que PANSS total apresentou p = 0,012 e Exp (B) = 1,06. Conclusão: Identificar os fatores associados à resistência precoce ao tratamento poderia permitir aos clínicos evitar o atraso na introdução da clozapina e prevenir um pior prognóstico para esses pacientes.
