Aims: This study aimed to systematically compare the effectiveness, safety, and costs of different anti‐Parkinson drugs (APDs). Methods: This is a multi‐center study that retrospectively analyzed the data of 8420 outpatients with PD from 2014 to 2019 across 30 tertiary hospitals in China. The effectiveness was evaluated by changes in total dosages of APDs, normalized by levodopa equivalent dose (LED) and presented as ΔLEDs; levodopa equivalent dose cost (LEDc) represented the daily cost of APDs; and newly added diagnostics were represented as APDs‐related adverse events. Results: A total of 384 patients with eligible medical records for three consecutive years were enrolled. Patients treated with carbidopa/levodopa or levodopa/benserazide had significantly lower mean ΔLEDs than other groups (p < 0.01), followed by pramipexole and selegiline. The piribedil group had the highest ΔLEDs, with mean differences of 112.56–355.04 mg compared to other groups (p < 0.01). Meanwhile, LEDc in the levodopa/benserazide, carbidopa/levodopa, and piribedil groups were significantly lower than those in pramipexole or selegiline groups ($0.088–0.135/day for levodopa/benserazide; $0.070–0.126/day for carbidopa/levodopa; $0.112–0.138/day for piribedil; $0.290–0.332/day for pramipexole; $0.229–0.544/day for selegiline; p < 0.01). Patients with piribedil had more adverse events, with an incidence rate of 35.7%, followed by levodopa/benserazide (25.6%), selegiline (23.5%), carbidopa/levodopa (23.3%), and pramipexole (16.4%). Pramipexole showed a lower incidence rate of adverse events than piribedil, including neuropsychiatric symptoms (p = 0.006), headache/dizziness (p = 0.016), and gastrointestinal symptoms (p = 0.031). Conclusions: Carbidopa/levodopa or levodopa/benserazide might exhibit better clinical improvement with less medical cost, while piribedil presented less clinical improvement but a higher risk of headache/dizziness, gastrointestinal, and neuropsychiatric symptoms.

Aim: Examining the association between HLA-A/B alleles and different carbamazepine (CBZ)-induced cutaneous adverse reactions in the Chinese population. Methods: A systematic review and meta-analysis of case-control studies was conducted. A systematic search was conducted of PubMed, Embase, the Cochrane Library, National Knowledge Infrastructure, the Chinese Biomedical Literature database and Wanfang Digital Periodicals. Results: 23 studies with a total of 1174 patients were included. In the Han population, HLA-B*15:02 is significantly associated with the increased risk of CBZ-related Stevens-Johnson syndrome/toxic epidermal necrolysis, and this correlation was not related to geographic distribution. HLA-A*31:01 , B*38:02 are associated with CBZ-related maculopapular eruption in South Han population. HLA-A*31:01 is associated with CBZ-DRESS in Taiwan Han population. Conclusion: HLA-B*15:02, A*31:01 and B*38:02 genes were found to be involved in the occurrence of CBZ cutaneous adverse reactions in Han Chinese.
