Mycophenolate mofetil (MMF) is an immunosuppressive prodrug approved for use in transplantation. Its active metabolite, mycophenolic acid, is mainly metabolized by UDP-glucuronosyltransferase (UGT) enzymes. In this study, we retrospectively analyzed 74 kidney transplant patients who had been prescribed MMF as part of their immunosuppression regimen.(More)
The aim of this study was to describe the demographic, clinical and laboratory features of idiopathic acute transverse myelitis (IATM). Patients with non-compressive ATM receiving care at Hospital da Lagoa, Rio de Janeiro (Brazil) between 2000 and 2008 were selected. Of the 70 cases of acute myelopathies, the idiopathic form was identified in 41 following(More)
Polymorphisms within genes encoding glutathione S-transferases (GSTs) may affect responses against damage induced by oxidative stress and therefore play a role to prevent chronic allograft dysfunction (CAD). In the present study, we estimated the frequencies of GSTM1- and GSTT1-null genotypes among 227 renal transplant recipients seeking to establish an(More)
BACKGROUND The visual evoked potential (VEP) is used in the evaluation of multiple sclerosis (MS) patients, showing a delay in P100 wave latency with no changes in amplitude in 60-100% of cases. In the last decade, the recurrent form of neuromyelitis optica (NMO) has been recognized, and clinically characterized by acute events of transverse myelitis (TM)(More)
BACKGROUND AND PURPOSE During the last two decades, clinical reports have begun to place increasing emphasis on the possible neurological complications related to dengue. However, reports of cases with myelitis post dengue are rare. This study describes an unprecedented cluster of transverse myelitis following a dengue virus infection. METHODS 51 possible(More)
BACKGROUND The anti-aquaporin4 (anti-AQP4) antibody is specific for neuromyelitis optica (NMO), but is also found in limited forms. The presence of this antibody in acute transverse myelitis (ATM) has been associated with recurrence and conversion to NMO, but the influence on disability has not yet been described. OBJECTIVE To describe the frequency of(More)
The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.4%-27.5%) living in areas of low MS prevalence.(More)
The aim of this study was to analyze the HLA class II alleles in neuromyelitis optica (NMO) and MS patients from Rio de Janeiro to clarify whether the pattern of genetic predisposition in NMO is different from the one seen in MS or whether it is possible to determine specific alleles of susceptibility or resistance. The DR3 haplotype was over represented in(More)
