RESUMO
INTRODUCTION: Contrast-induced acute kidney injury (CI-AKI) is a serious complication of coronary angiography (CA). The aim of this randomized, parallel group, single blind, sham-controlled trial was to assess the safety and efficacy of the remote ischemic preconditioning on the prevention of CI-AKI. METHODS: Patients of 18-80 years of age with CKD 3 and 4, who were admitted for elective coronary angiography in a tertiary care hospital in eastern India were randomized in a 1:1 ratio to standard care with ischemic preconditioning (n = 45; intermittent arm ischemia through 4 cycles of 5-min inflation and 5-min deflation of a blood pressure cuff) or with standard care and sham ischemic preconditioning (n = 42). Overall, both study groups were at moderate risk of developing CI-AKI according to the Mehran risk score. The primary endpoint was the incidence of CI-AKI, defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dL above baseline at 48 h after contrast medium exposure. RESULTS: CI-AKI occurred in 8 patients (19.04%) in the control group and 2 (4.4%) in the remote ischemic preconditioning group (odds ratio, 0.198, 95% confidence interval, 0.087 to 0.452; P = 0.04). No major adverse events were related to remote ischemic preconditioning. CONCLUSIONS: This study indicates that remote ischemic preconditioning is a simple and well-tolerated procedure, which reduces the incidence of CI-AKI in CKD 3 and 4 patients undergoing coronary angiography.
RESUMO
INTRODUCTION: Acute disseminated encephalomyelitis (ADEM) is a monophasic, inflammatory, immune-mediated disorder of the central nervous system. It is particularly difficult to distinguish between ADEM and an initial attack of multiple sclerosis (MS) clinically and based on magnetic resonance imaging (MRI) or cerebrospinal fluid. ADEM is quite rare after malaria infection. Our patient, although diagnosed provisionally of ADEM after mixed malaria infection, had neuroimaging closely simulating MS. CASE REPORT: We report a case of a woman with an adult type 2 diabetes presenting with fever and diagnosed by antigen assay to be suffering from mixed malaria infection (Plasmodium falciparum, Plasmodium vivax). While recovering with artesunate and doxycycline therapy, she developed acute onset bladder retention followed by paraparesis. On examination she had evidence of Upper Motor Neuron (UMN) signs in all the 4 limbs along with truncal sensory loss. DISCUSSION: Her MRI of spine showed T2 hyperintensities suggestive of resolving myelitis. MRI of the brain showed multifocal and confluent areas of demyelination mostly involving the corpus callosum and periventricular region. Lesions, particularly the callosal ones, closely simulated MS. In accordance with the McDonald Criteria and Barkhof's MRI Criteria, this patient did not fit into the diagnosis of MS. Our provisional diagnosis was ADEM.
