Proprotein convertase subtilisin/kexin type 9 (PCSK9) has attracted lots of attention in preventing the clearance of plasma low‐density lipoprotein cholesterol (LDL‐C). PCSK9 inhibitors are developed to primarily reduce the cardiovascular risk by lowering LDL‐C level. Recently, a number of pleiotropic extrahepatic functions of PCSK9 beyond the regulation of cholesterol metabolism, particularly its effects on central nervous system (CNS) diseases have been increasingly identified. Emerging clinical evidence have revealed that PCSK9 may play a significant role in neurocognition, depression, Alzheimer's disease, and stroke. The focus of this review is to elucidate the functions of PCSK9 and highlight the effects of PCSK9 in CNS diseases, with the aim of identifying the potential risks that may arise from low PCSK9 level (variant or inhibitor) in the clinical practice.

Half of the world's population is Helicobacter pylori carrier. Updated guidelines and consensus have been issued across regions with the main aim of reducing social transmission and increasing H. pylori eradication rate. Although alternative therapies including traditional Chinese medicine and probiotics have also been used to improve H. pylori eradication rate in clinical practice, current mainstream treatment is still dependent on triple and quadruple therapies that includes antibacterial agents (e.g., amoxicillin and furazolidone) and proton pump inhibitor. Researches also assessed the eradication rate of optimized high‐dose dual therapy in treating H. pylori infection. With the increase of antibiotic resistance rate, the treatment strategies for H. pylori infection are constantly adjusted and improved. Besides, low medication compliance is another key influencing factor for H. pylori treatment failure. Emerging studies indicate that pharmacists' intervention and new pharmaceutical care methods can enhance patient medication compliance, reduce adverse drug reactions, and improve H. pylori eradication rate. The purpose of this review is to summarize the advances in treating H. pylori infection and highlight the necessity of developing novel strategies to cope with the increasing challenges and to achieve personalized medication. Also, this review attaches great importance to pharmacists in optimizing H. pylori treatment outcomes as a routine part of therapy. [ABSTRACT FROM AUTHOR]
