Abstract

Introduction. Pneumofibrosis (PF) is a morphological outcome of acute and chronic lung diseases, the progression of which leads to organ deficiency.Aim. Development of a prognostic algorithm for assessing the risk of progression of post-inflammatory PF in children with chronic nonspecific lung diseases (CNSLD).Materials and methods. The examination of 52 children with CNSLD with focal post-inflammatory PF was conducted, of which 26 children with progressive PF and 26 children with non-progressive PF. The children were selected according to the “case-control” scheme. The patients had a dynamic clinical and laboratory examination with multispiral computed tomography of the lungs. Determination of the “zero” genotypes of the detoxification genes GSTM1, GSTT1 was carried out by means of polymerase chain reaction. The odds ratio indicator was used to assess the relative risk.Results. Based on the analysis of medico-social, clinical characteristics and genetic polymorphism, an individual prognostic algorithm for the risk of progression of post-inflammatory PF in children with CNSLD was developed. The algorithm includes the calculation of the total score (TS) of 7 medical and social indicators (living in an urban area; the presence of passive smoking; the duration of a pulmonological history of 4-9 years; the presence of congenital lung malformation; the number of acute respiratory infections (ARI) 4 or more times/year; the duration of ARI 11 days or more; taking antibiotics for more than 3 once/year) and the presence of deletions in the detoxification genes GSTM1 and GSTT1. With a value of TS 6.97 or more, a high risk of progression of PF is predicted, with TS 3.47-6.96 points, a moderate risk of progression of PF is diagnosed, with TS 3.46 or less points, a minimal risk of progression of PF.Conclusion. The proposed algorithm allows predicting the risk of progression of post-inflammatory PF in children with CNSLD at the stage of early diagnosis and will prevent the spread of the process in the lungs with the help of preventive measures and preventive therapy, which will increase the duration and improve the quality of life of the patient.
