© 2020 Elsevier B.V. Alprazolam is used in the treatment of patients with anxiety disorders comorbid with alcohol use disorder. Some proportion of these patients does not respond adequately to treatment with alprazolam, while many of them experience dose-dependent adverse drug reactions. Results of the previous studies have shown that CYP3A is involved in the biotransformation of alprazolam, the activity of which is dependent, inter alia, on the polymorphism of the encoding gene. Objective: The objective of our study was to investigate the effect of 99366316G>A polymorphism of the CYP3A4 gene on the concentration/dose indicator of alprazolam in patients with anxiety disorders comorbid with alcohol use disorder, using findings on enzymatic activity of CYP3A (as evaluated by the 6-beta-hydroxy-cortisol/cortisol ratio measurement) and on CYP3A4 expression level obtained by measuring the miR-27b plasma concentration levels in patients with anxiety disorders comorbid with alcoholism. Material and methods: Our study enrolled 105 patients with anxiety disorders comorbid with alcohol use disorder (age - 37.8±14.6 years). Therapy included alprazolam in an average daily dose of 5.6±2.4 mg per day. Treatment efficacy was evaluated using the psychometric scales. Therapy safety was assessed using the UKU Side-Effect Rating Scale. For genotyping and estimation of the microRNA (miRNA) plasma levels, we performed the real-time polymerase chain reaction. The activity of CYP3A was evaluated using the HPLC-MS/MS method by the content of the endogenous substrate of the given isoenzyme and its metabolite in urine (6- beta-hydroxy-cortisol/cortisol). Therapeutic drug monitoring (TDM) has been performed using HPLC-MS/MS. Results: Our study revealed the statistically significant results in terms of the treatment efficacy evaluation (HAMA scores at the end of the treatment course): (GG) 3.0 [2.0; 5.0] and (GA) 4.0 [4.0; 5.0], p = 0.007; at the same time, the statistical significance in the safety profile was not obtained (the UKU scores): (GG) 3.0 [2.0; 3.8] and (GA) 3.0 [1.5; 4.0], p = 0.650. We revealed a statistical significance for concentration/dose indicator of alprazolam in patients with different genotypes: (GG) 1.583 [0.941; 2.301] and (GA) 2.888 [2.305; 4.394], p = 0.001). Analysis of the results of the pharmacotranscriptomic part of the study didn't show the statistically significant difference in the miR-27b plasma levels in patients with different genotypes: (GG) 25.6 [20.4; 28.8], (GA) 25.7 [19.7; 33.1], p = 0.423. At the same time, correlation analysis revealed a statistically significant relationship between the alprazolam efficacy profile evaluated by changes in HAMA scale scores and the miR-27b plasma concentration: rs = 0.20, p = 0.042. Also, we didn't reveal the correlation between the miRNA concentration and safety profile: rs = 0.15, p = 0.127. In addition, we revealed the relationship between the CYP3A enzymatic activity (as evaluated by 6-beta-hydroxycortisol/ cortisol ratio measurement) and the miR-27b plasma concentration: rs = −0.27, p = 0.006. At the same time, correlation analysis revealed a statistically significant relationship between the alprazolam concentration and the miR-27b plasma concentration: rs = 0.28, p = 0.003. Conclusion: The effect of genetic polymorphism of the CYP3A4 gene on the efficacy and safety profiles of alprazolam was demonstrated in a group of 105 patients with anxiety disorders comorbid with alcohol use disorder. At the same time, miR-27b remains a promising biomarker for assessing the level of CYP3A4 expression, because it correlates with the encoded isoenzyme's activity.

Non-small cell lung carcinoma (NSCLC) is the major cause of cancer-associated mortality. Identification of rearrangements in anaplastic lymphoma kinase (ALK) gene is an effective instrument for more effective targeted therapy of NSCLC using ALK inhibitors dramatically raising progression-free survival in the ALK-mutated group of patients. However, the tumors frequently develop resistance to ALK inhibitors. We describe here a case of 48 y.o. male patient with ALK-positive NSCLC who was clinically managed for 6.5 years from the diagnosis. The tumor was surgically resected, but 8 months later multiple brain metastases were discovered. The patient started receiving platinum-based chemotherapy and then was enrolled in a clinical trial of second-generation ALK inhibitor ceritinib, which resulted in a 21 months stabilization. Following disease relapse, the patient was successfully managed for 33 months with different lines of chemo- and local ablative therapies. Chemotherapy regimens, including off-label combination of crizotinib + bevacizumab + docetaxel, were selected using the cancer transcriptome data-guided bioinformatical decision support system Oncobox. These therapies led to additional stabilization for 22 months. Survival of our patient after developing resistance to ALK inhibitor was longer for 16 months than previously reported average survival for such cases. This case shows that transcriptomic-guided sequential personalized prescription of targeted therapies can be effective in terms of survival and quality of life in ALK-mutated NSCLC.

© 2018 Sychev et al. Purpose: The aim of this study was to determine the impact of ABCB1 (MDR1) rs1045642 polymorphisms on the efficacy and safety of amlodipine in Caucasian patients. Patients and methods: The 12-week study included 100 patients. Patients with the newly diagnosed stage I–II hypertension (HT) were recruited to complete genotyping of the rs1045642 single-nucleotide polymorphism (SNP). The study design did not include a control group. Before treatment, all patients either did not undergo antihypertensive treatment at all or did not receive regular antihypertensive therapy. The initial dose was 5 mg/day. Four office blood pressure measurements, two 24-hour noninvasive ambulatory blood pressure measurements, and questionnaires of Tsvetov were used to evaluate the efficacy and safety of amlodipine. Results and conclusion: The highest antihypertensive effect in combination with the lowest incidence of adverse reactions was observed in the TT group, while patients with the CC genotype showed a low antihypertensive effect and the highest incidence of adverse effects. Patients with the CC genotype presented with adverse effects predominantly in the form of edema. A total of 33 patients reached the target blood pressure (SBP <140 mmHg; DBP <90 mmHg): two patients with the CC genotype (12%); 18 patients with the CT genotype (34%); and 13 patients with the TT genotype (43%). The intergroup differences were: CC vs CT, P=0.02; CC vs TT, P=0.02; and CT vs TT, P=0.05. The results of this study indicate the potential of pharmacogenetic testing for rs1045642 SNP when prescribing amlodipine for the first time in Caucasian patients with stage I–II arterial HT.

BACKGROUND: Alcohol dependence is often combined with affective disorders, in particular, depressive disorder (DD), which worsens adversely affects the prognosis of the course of both diseases and their outcomes. For the treatment of DD, drugs from the group of selective serotonin reuptake inhibitors, whose representative is fluvoxamine, are used. Fluvoxamine therapy is often associated with a risk of development is shown to be ineffective, and a part of patients develop dose-dependent adverse drug reactions (ADR) and pharmacoresistance. OBJECTIVE: To study the effects of CYPD6 isoenzyme activity on the efficacy and safety of fluvoxamine therapy in patients with depressive disorders, comorbid with alcoholism. METHODS: The study was conducted on 117 Russian patients with DD, alcohol-dependent comorbid. For the purpose of correction of depressive disorders within the framework of cyclothymia, fluvoxamine (Fevarin) was administered to patients at a dosage of 50−150 mg/day. Genotyping was carried out by the method of polymerase chain reaction in Real-time mode with allele-specific hybridization. Efficacy and safety were assessed using validated psychometric scales and an assessment of the severity of ADR. To evaluate the activity of CYP2D6, the method of high performance liquid chromatography with mass spectrometry was used to measure the urinary content of the endogenous substrate of this isoenzyme and its metabolite, the ratio of 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline. RESULTS: By the 9th day of the study, the severity of depressive symptoms on the HAMD scale was statistically significantly different in patients with different genotypes: (GG) 7.0 [6.0; 8.0], (GA) 4.0 [3.0; 5.0] (p<0.001); safety indicator, estimated on a UKU scale: 3.0 [2.0; 4.0], (GA) 4.0 [4.0; 4.2] (p<0.001). The presence of differences persisted on the 16th day: (GG) 5.0 [3.0; 6.0], (GA) 1.5 [1.0; 3.0] (p<0.001); safety indicator, estimated on a UKU scale: (GG) 9.0 [9.0; 10.0], (GA) 6.0 [6.0; 7.0] (p<0.001). The calculation of the correlation coefficients between the difference in the number of scores on psychometric scales and the metabolic ratio showed a statistically significant inverse correlation of the average power degree between the efficiency index estimated by the HAMD scale (r=-0.467, p<0.05). There was no connection with the difference on the UKU scale (r=0.173, p>0.05). CONCLUSION: In a study of a group of 117 patients with DD, comorbid with alcohol dependence, the effect of CYP2D6 activity, estimated by the ratio of the endogenous substrate concentrations of pinolin and its metabolite 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline, on the efficacy of fluvoxamine therapy. This effect was also shown using the results of genotyping. The results of genotyping also showed the existence of a difference in the safety index in patients with different genotypes from the polymorphic marker CYP2D6 1846G>A.
