RESUMO
BACKGROUND: Ankylosing spondylitis (AS) is a chronic inflammatory disease known for causing pain, stiffness, and reduced mobility in the axial skeleton. Adalimumab, a tumor necrosis factor (TNF) inhibitor, has emerged as a promising therapeutic option for AS. METHODS: This systematic review involved a comprehensive search of randomized controlled trials related to AS treatment, conducted in major databases such as MEDLINE, Google Scholar, and PubMed. The search terms encompassed ankylosing spondylitis, adalimumab, methotrexate, other non-biologic DMARDs, glucocorticoids, NSAIDs, and analgesics. A total of 14 randomized controlled trials with 4,500 participants were included in the review. RESULTS: The review's results revealed that adalimumab demonstrated notable superiority when compared to a placebo. It effectively reduced disease activity, improved physical function, and lowered inflammatory markers such as C-reactive protein and erythrocyte sedimentation rate. Adalimumab demonstrated a favorable safety profile, with adverse events comparable to those observed with placebo. CONCLUSION: Based on the results, adalimumab is deemed an effective treatment for AS, showcasing its potential as a first-line therapeutic option. Notably, no significant increase in adverse events was observed compared to placebo. However, the conclusion emphasizes the need for further studies with extended follow-up durations to ascertain the long-term efficacy and safety of adalimumab in AS management. This systematic review provides valuable insights supporting the use of adalimumab in the treatment of AS and underscores the importance of ongoing investigations into its long-term effects to optimize its clinical utilization in AS patients.

INTRODUCTION: Fluoxetine is used in the treatment of patients with recurrent depressive disorder. Some of these patients do not achieve an adequate response to a treatment regimen containing fluoxetine, and many of these patients experience dose-dependent adverse drug reactions. The cytochrome P450 enzyme CYP2D6 is involved in the biotransformation of fluoxetine, the activity of which is quite dependent on the polymorphism of the gene encoding this enzyme. OBJECTIVE: The objective of the study was to investigate the influence of the 1846G>A polymorphism of the CYP2D6 gene on the concentration/dose indicator of fluoxetine in patients diagnosed with major depressive disorder and comorbid alcohol use disorder. METHODS: Our study included 101 patients with major depressive disorder and alcohol use disorder (average age: 41.3±14.5 y) who were treated with fluoxetine at an average dose of 26.1±8.7 mg/d. Treatment efficacy was assessed using validated psychometric scales, and the safety/tolerability of the therapy was assessed using the Udvalg for Kliniske Undersogelser Side-Effect Rating Scale. Genotyping was done using a real-time polymerase chain reaction. Therapeutic drug monitoring was performed using high-performance liquid chromatography-mass spectrometry. RESULTS: CYP2D6 genotyping by polymorphic marker 1846G>A (rs3892097) in the 101 patients found that there were 81 patients (80.2%) with the GG genotype ("wild-type," normal metabolism), 20 (19.8%) with the GA genotype (intermediate metabolism), and no subjects with the AA genotype (poor metabolism). Statistically significant results in treatment efficacy as evaluated by Hamilton Rating Scale for Depression scores at the end of the treatment course were found: GG 9.0 [confidence interval (CI): 6.0; 12.0] and GA 12.0 (CI: 9.5; 14.0), P=0.005. Statistically significant results were also obtained for the safety profile as measured by scores on the Udvalg for Kliniske Undersogelser Side-Effect Rating Scale: GG 3.0 (CI 2.0; 4.0) and GA 5.0 (CI: 4.0; 5.0), P<0.001. Finally, a statistically significant difference was found in concentration/dose indicators of fluoxetine in patients with the different genotypes: GG 4.831 (CI: 3.654; 6.204) and GA 7.011 (CI: 5.431; 8.252), P<0.001. CONCLUSION: The effect of the genetic polymorphism of the CYP2D6 gene on the efficacy and safety profiles of fluoxetine was demonstrated in a group of 101 patients with major depressive disorder and alcohol use disorder.

This review is about the significance of the use of lipidomic analysis for identifying susceptibility to skin diseases. Exactly this article describes the use of lipidomic analysis in different studies to detect abnormalities in the lipid composition of the skin to diagnose and prevent various dermatological diseases.
RESUMO
2-ethyl-6-methyl-3-hydroxypyridine (EMHP) succinate is the original antioxidant and antihypoxic drug commonly prescribed in Russia. The objective of this study was to develop a rapid, simple and sensitive high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for EMHP quantitation in rat brain tissue with the use of a bead beating homogenizer. The comparison between two approaches to brain tissue preparation was performed, when spiking the blank brain tissue with EMHP reference standard and internal standard (IS) before and after homogenization step. Chromatographic separation was achieved using Zorbax Eclipse Plus C18 column (1.8⯵m, 2.1â¯×â¯50â¯mm) and elution was performed with the mobile phase, consisting of 10â¯mM of ammonium formate aqueous solution with 0.1% formic acid as solvent A and 0.1% formic acid in methanol as solvent B [44%(Ð):56%(Ð), v/v]. Flow rate was 0.4â¯mL/min and the total run time for each sample analysis was 2.0â¯min. EMHP and amantadine, IS of this study, were analyzed in positive ionization mode. Ion transitions of m/z 138.0â¯ââ¯123.0 for EMHP and m/z 152.0â¯ââ¯135.0 for amantadine were selected in multiple reaction monitoring mode. The developed method for EMHP determination in rat brain samples was validated for selectivity, linearity, accuracy, precision, matrix effects, and stability. The lower and upper limits of quantification were determined to be 1 and 1500â¯ng/g, respectively. The developed and validated HPLC-MS/MS method was successfully applied to determine EMHP concentrations in rat brain tissue following the intraperitoneal administration at a dose of 3.4â¯mg/kg.
