Background: The effect of repeated intravenous amantadine (IVAM) in advanced Parkinsonism has not been studied in depth.

Objectives: To report the experience of our medical center with repeated IVAM infusions in patients with advanced Parkinsonism.

Methods: Thirty patients with advanced Parkinsonism of various etiologies were enrolled in an open-label retrospective study. All patients were treated with IVAM infusions in a neurological daycare center. Treatment was initiated with a loading dose of 200/400 mg per day for 5 days followed by a once-daily maintenance dose of 200/400 mg every 1 to 3 weeks. Patients and their caregivers participated in a structured interview and independently completed a clinical global impression of changes scale questionnaire on various motor and non-motor symptoms.

Results: Patient mean age was 73.3 ± 9.7 years, average disease duration was 6.2 ± 5.7 years, and mean Hoehn and Yahr score was 3.2 ± 0.84. Mean duration of the IVAM treatment was 15.1 ± 11.6 months. An improvement in general function was reported by 91% of the patients and 89% of the caregivers. Most of the patients reported improvement in tremor and rigidity, as well as in gait stability, freezing of gait, and reduced falls. The treatment was safe with few side effects.

Conclusions: Our data suggest that repeated IVAM infusions could be an effective treatment against various motor symptoms and for improvement of mobility in patients with advanced Parkinsonism. Further randomized clinical trials with a larger sample size using objective measures are warranted to validate our results.

Background: Contemporary therapies improve prognosis and may restore left ventricular (LV) size and function.

Objectives: To examine the prevalence, clinical features and therapies associated with reverse remodeling (RR) in dilated cardiomyopathy (DCM).

Methods: The study group comprised 188 DCM patients who had undergone two echo examinations at least 6 months apart. RR was defined as increased LV ejection fraction (LVEF) by ≥ 10% concomitant with ≥ 10% decreased LV end-diastolic dimension.

Results: RR occurred in 50 patients (26%) and was associated with significantly reduced end-systolic dimension, left atrial size, grade of mitral regurgitation, and pulmonary artery pressure. NYHA class improved in the RR group. RR was less common in familial DCM and a long-standing disease and was more prevalent in patients with prior exposure to chemotherapy. Recent-onset disease, lower initial LVEF and normal electrocardiogram were identified as independent predictors of RR. Beta-blocker dose was related to improved LVEF but not to RR. Over a mean follow-up of 23 months, 16 patients (12%) from the 'no-RR' group died or underwent heart transplantation compared to none from the RR group (P < 0.01).

Conclusions: Contemporary therapies led to an an improvement in the condition of a considerable number of DCM patients. A period of close observation while optimizing medical therapy should be considered before deciding on invasive procedures.
