Determination of somatic status of girls with chronic vulvovaginitis in the neutral period of life

Abstract

The objective: a determination of the spread of somatic pathology and polymorphism of the MSM6 gene in the development of chronic recurrent vulvovaginitis in girls. Materials and methods. The study involved 54 girls 1–6 years old. Inclusion criteria: complaints of patients on itching or pain in the genital area, dysuria, the presence of synechiae of the vulva, clinical manifestations of vulvitis during the visual examination. General laboratory diagnostic methods were used (blood test, general urine analysis with determination of ketone bodies, bacterioscopic examination of vaginal smears, vaginal culture for flora and antibiotic sensitivity, determination of glucose levels in blood serum and urine). For diagnosis of lactose malabsorption by polymerase chain reaction, a mutation in the MCM6 gene was studied, the genetic marker of which is C (-13910). Results. The somatic status of patients with chronic vulvovaginitis was presented by pathology of the gastrointestinal digestive tract in 68.5 % cases, atopic dermatitis – 53.7 %, diseases of the respiratory system – 33.3 %, infectious processes of the kidneys and urinary tract – 24.1 %. 77.6 % of girls had nondiabetic acetone syndrome, 75.9 % – dysmetabolic nephropathy. The presence of lactose malabsorption was revealed by homozygosity for the MCM6 gene mutation (C/C) in 26.1% of patients, heterozygosity for the MCM6 gene mutation (C/T) - in 56.5 %, the absence of the MCM6 gene mutation (T/T) was in 8 (17.4 %). Conclusions. In girls in the neutral period of life with chronic vulvovaginitis, non-infectious forms of the disease were found, which were not independent pathology, but associated with other pathological processes of metabolic disorders. Taking into account the obtained data on lactose malabsorption, we consider to include in the examination the algorithm of the verification of the MCM6 gene mutation and examination of urine for lactosuria and blood with lactose load.
