Lipid spectrum of cell membranes and blood plasma in adolescents with recurrent cephalgia associated with arterial hypertension. Methods of correction

Purpose. To study the characteristics of the content of neutral lipids and phospholipid fractions in the membranes of erythrocytes and blood plasma of adolescents with cephalalgia and arterial hypertension (AH). Materials and methods. Subject of the study – adolescents 12–17 years old (boys and girls) with cephalgia and the presence of AH (main group) and without AH (comparison group). Methods: questionnaires, laboratory, statistical. Examination program: verification of the clinical form of cephalgia (episodic, chronic); assessment of the presence of AH (using percentile tables, taking into account age, gender and height percentile); determination of the concentration of neutral lipids and phospholipid fractions in blood plasma and erythrocyte membranes using thin layer chromatography. Results. Of the 64 examined adolescents – patients of the pediatric department with recurrent cephalgia, the frequent (chronic) form of cephalgia was verified in 40 (62.5%) people, AH was diagnosed in 10 (25.0%) adolescents with chronic cephalgia and in 30 (75.0%) adolescents with this form of cephalalgia AH were not identified. Features of the lipid spectrum of adolescents with a chronic form of cephalgia associated with AH included a lower concentration of total lipids and triglycerides in erythrocyte membranes, higher values of the general phospholipids/free cholesterol ratio and a smaller number of statistically significant correlations. Conclusion. The features we identified in the lipid spectrum of erythrocyte membranes and blood plasma in adolescents with a frequent (chronic) form of cephalalgia associated with AH may indicate the presence in adolescents of initial minimal changes in the biochemical status of cell membranes at the stages of development of cardiovascular pathology – hypertension and coronary heart disease.
