OBJECTIVE: To describe the rate of suicide and explore its possible related factors among patients with X-linked Dystonia Parkinsonism. Specifically, this paper aimed to describe the rate of suicide among patients with XDP based on the Philippine XDP registry and to describe these patients in terms of severity of XDP and psychosocial factors.
BACKGROUND: Chronic progressive neurologic conditions have been associated with serious psychosocial stresses. Suicide among patients with X-linked Dystonia Parkinsonism has been previously reported to be high.
METHODS: A retrospective chart review was done on XDP patients with deaths attributable to suicide. XDP related variables and available psychosocial factors were noted.
RESULTS: The prevalence of suicide among all XDP patients registered is 4.16%. There are 194 deaths in the Philippine XDP registry, 21 of which were attributable to suicide, a proportion of 10.8%. Their mean age at suicide was 44, around 7.76 mean years from the onset of illness. All of the patients were either in generalized dystonia or parkinsonian stage when they had suicide. Psychosocial variables noted were marital and family conflict, and loss of employment. None of the patients had a prior documented psychiatric illness but several of them showed symptoms of depression prior to suicide.
CONCLUSIONS: There is a high rate of suicide among patients with XDP which is comparable to other disabling neurodegenerative diseases. It occurs relatively late in the course where the patient is already in the stage of generalized dystonia or parkinsonism. Possible psychosocial risks include poor family support, marital conflict, loss of employment and symptoms suggestive of depression. The present understanding is that depression and suicide in XDP is more likely reactive to the disease rather than part of its clinical feature. This study supports this view.

BACKGROUND: XDP is an X-linked recessive disorder characterized by parkinsonism and dystonia described among Filipinos. Oral medications are frequently ineffective. Lately, DBS have been promising. However these are not generally available or affordable for the vast majority of patients. We then decided to evaluate the effectiveness of levodopa-carbidopa for XDP.
OBJECTIVE: To compare the efficacy, safety and tolerability of levodopa-carbidopa vs. placebo in XDP patients.
METHODS: After informed consent and randomization, the BFM and the UPDRS parts III and IV were performed at baseline and monthly up to 6 months. Patients were randomized to receive either levodopa-carbidopa at a starting dose of 125 mg levodopa/ day in 2 divided doses or corresponding placebo. Gradual uptitration was done to a maximum of 1000 mg levodopa/ day or until side effects appeared.
Homogeneity of the characteristics of patients in the 2 groups was determined using Independent t-test and Chi-square test. To determine the significance of changes in the efficacy parameters within each group, Wilcoxon Matched Pairs Signed Ranks Test was used. To compare the scores of the different efficacy parameters of the 2 groups, Mann Whitney U Test was applied to the data. A p?0.050 was considered significant.
RESULTS: A total of 107 patients were recruited. There were 13 screen failures, and 94 were subsequently enrolled. The baseline characteristics (age, duration of illness, baseline BFM and UPDRS (motor) scores were not significant between levodopa and placebo (age in years: 47 + 9.35 vs. 50 + 9.51; duration of illness in years 6.3 + 7 vs. 6.2 + 5.2; BFM score: 32.8 + 24.5 vs. 28.4 + 26.5; UPDRS score 29.9 + 20.7 vs. 34.8 + 26.8).
There was a decrease in BFM scores from baseline to all follow-up periods in patients given levodopa but were statistically significant only on visit 2 and visit 9. In the placebo group, decrease in scores was also observed in some observation periods but no statistical significance was shown. A comparison of the 2 groups showed that the magnitude of decrease in the levodopa group was statistically greater than the placebo group on the second visit. There were no significant differences observed in all other follow-up periods. Both groups showed a decrease in UPDRS scores but significant decrease was observed in visits 2, 5, 6, 7, 9 of the levodopa group. While in the placebo group, a significant decrease was observed only on visit 2. Comparison of the 2 groups did not show any significant differences.
There were 17 patients from the levodopa group who reported adverse events (most common: increased involuntary movements, nausea/ vomiting/ dizziness, headache, and generalized weakness. In the placebo group, there were 11 patients (most common: increased involuntary movements, abdominal pain). There were 9 patients who dropped out (levodopa: 4, placebo: 5).
CONCLUSION: There was a significant decrease in the BFM and UPDRS scores in XDP patients given levodopa compared to placebo. Levodopa is a safe and effective drug that may be considered in patients with XDP.

X-linked dystonia parkinsonism (XDP) is a rapidly progressive and disabling neurodegenerative disease affecting mainly male Filiponos with origins from Panay Island. We reviewed all the past neurosurgical ablative procedures done for XDP patients listed in the Philippine XDP registry. From 1960 to 1982, six patients had undergone bilateral chemopallidotomies or bilateral thalomotomies stage over time. Half of these patients had significant improvement in their symptoms but five of the six patients (83%) developed postoperative morbidities, mainly speech impairment or hemiparesis, All the five reported GPi deep brain stimulation (DBS) cases for XDP were also reviewed, showing consistently immediate improvement of symptoms (61.5%-88.3% decrease in the Burke-Marsden Dystonia Rating Scale) lasting up to a year with effects noted. We also present the first Philippine case of GPi DBS done in the youngest XDP patients to date. This present case showed dramatic improvement(83.3% desrease of the Burke-Marsden_Fahn Dystonia Rating Scale) of his dystonic symptoms, without incurring any persistent adverse effects. The results of these early cases of pallidal DBS for XDP show that DBS is generally a safe and effective procedure for alleviating the disabling symptoms of XDP in contrast to previous ablative surgeries on these patient

Hydroxychloroquine (HCQ) has been used as an investigational drug for patients with moderate to severe coronavirus disease 2019 (COVID-19). There have been concerns of potential harms from side effects of the drug. We present a case of a 38-year-old male who was started on HCQ for COVID-19 pneumonia. He was referred for evaluation of myoclonus of all extremities, which resolved after discontinuation of HCQ. The involuntary movements were first reported after the initiation of HCQ, persisted despite improvement in inflammatory and radiologic parameters and eventually resolved after HCQ discontinuation. This supports a possible causality related to adverse drug reactions from HCQ that have not been commonly reported.

INTRODUCTION: Coenzyme Q10, also known as Ubiquinone, is a substance now being used as a dietary supplement in many countries including the Philippines. It has also been the focus of several researches as treatment for several diseases including Parkinson's Disease. Several studies have shown that Coenzyme Q10 inhibits mitochondrial dysfunction in Parkinson's Disease, hence delaying its progression.
OBJECTIVES: The objective of this study is to assess and summarize the available evidence on the efficacy and safety of Coenzyme Q10 administration in the prevention of the progression of early Parkinson's Disease.
METHODS: This is meta-analysis of randomized controlled trials on the use of Coenzyme Q10 in Parkinson's Disease. A literature search in several databases was conducted for relevant studies. Three randomized controlled trials met the inclusion criteria. The efficacy of Coenzyme Q10 were measured using the total and the component scores of the Unified Parkinson Disease Rating Scale on follow-up. On the other hand, safety were measured using the withdrawal rate and the associated adverse reactions during the therapy of CoQ10. The Review Manager Software was utilized for the meta-analysis.
RESULTS: Compared to Placebo, treatment of CoQ10 did not show any significant difference in the mean scores of the UPDRS mental and ADL scores. Interestingly, the UPDRS motor score showed a significant difference between Coenzyme Q10 and placebo, but no significant difference when a subgroup analysis between high-dose (-4.03 [-15.07-7.01], p-value 0.47, I2 67%, P for heterogeneity 0.08) and low-dose Coenzyme Q10 (0.53 [-0.89-1.94], p-value 0.47, I2 34%, P for heterogeneity 0.22) was done. Overall, there was no significant difference in the total UPDRS score (0.68 [-0.61-1.97], p-value 0.30, I2 0%, P for heterogeneity 0.70). The anxiety, back pain, headache, sore throat, nausea, dizziness and constipation.
CONCLUSION: Contrary to some animal and human studies, this meta-analysis showed that the use of CoQ10 results to non-significant improvement in all components of the UPDRS scores as opposed to placebo. However, the use of CoQ10 is tolerated and seems to be safe but further studies are needed to validate this finding.
