Since the introduction of enzyme replacement therapy (ERT), with recombinant human GAA for the early onset PD patient, a relevant field of clinical research due to the benefits regarding survival rate has been widely documented worldwide. Objective: To describe the clinical characteristics and the ERT effects in a series of Brazilian patients with infantile onset PD (IOPD) under ERT. Methods: Brazilian patients diagnosed with IOPD under ERT were recruited through their physicians participating in the International Pompe Disease Registry from 2009 to 2017. Data were collected by an online survey. Results: 10 IOPD patients were identified through the survey with a death rate of 30% and technology dependency rate reported as 80% (motor, respiratory or nutritional fields) of the patients. After the third year of ERT, motor disabilities were lost in 50% of ambulated patients. The overall characteristics were similar to international studies. Conclusion: Despite ERT benefits in cardiac involvement, motor disabilities seem to be much more compromised in IOPD patients, with high technology dependence, especially after three years of age.展开更多

Methods This retrospective observational study considered 538 older adults consecutively admitted, who had been followed-up for 31 ± 20 months. Subjects with poor short-term prognosis were excluded. Charlson comorbidity index （CCI） and estimated glomerular filtration rate （eGFR） was calculated, along with the independent relationship between all-cause mortality and clinical data. Hazard Ratio （HR） was calculated by Cox regression analysis. Results Mean age of the population was 85 ± 3.7 years, and causes for implantation were atrioventricular block in 51.9% and other bradyarrhythmias in 48.1% of cases. Mean eGFR was 58.3 ± 24 mL/min per 1.73 m2, and mean CCI was 3.65 ± 2.28. Death for all-causes was recorded in 213 subjects. Deceased patients were older, had lower eGFR, higher comorbidity, higher prevalence of myocardial infarction, congestive heart failure, cerebrovascular disease, dementia and chronic pulmonary disease. Age （HR： 1.081, 95% CI： 1.044-1.119; P 〈 001）, CCI （HR： 1.651, 95% CI： 1.286-2.121, P 〈 001） and eGFR 〈 45 mL/min per 1.73 m2 （HR： 1.360, 95% CI： 1.024-1.806; P = 0.033） were predictors of death. Conclusions Renal dysftmction, as well as comorbidity, impacts negatively survival of older adults treated with pacemaker implantation because of bradyarrhythmias.展开更多
