RESUMO
OBJECTIVE: to analyze comorbid pathology by methods of its quantitative assessment in servicemen exposed toextreme factors of military service (a set of factors of radiation accidents, the influence of modern armed conflictsand modern combat trauma without blood loss). MATERIALS AND METHODS: Studies of comorbid pathology were performed in 613 servicemen who were treated at theclinical base of the Ukrainian Military Medical Academy (UMMA) in National Military Medical Clinical Center «MainMilitary Clinical Hospital¼ NMMCC «MMCH¼ during 1989-2018 years. Soldiers who suffered from acute radiation sick-ness (ARS) in 1961 (n = 34), participants in the liquidation of the consequences of the Chornobyl catastrophe(PLCChC) 15 years after participating in the elimination of its consequences and in a later period (respectivelyPLCChC 1st group (n = 59) and the 2nd group (n = 337)). Soldiers are participants in the anti-terrorist operation(ATO)/Combined Forces (CFO) operation who did not receive modern combat injuries with blood loss (participants inthe ATO/CFO, n = 183). All servicemen did not have any diseases limiting their fitness capabilities for military serv-ice before being exposed to extreme factors of military service. A cumulative CIRS scale was used to comprehensive-ly assess comorbidity. RESULTS: With increasing time after participation in the elimination of the consequences of radiation accidents, thecourse of arterial hypertension (AH) is aggravated, but the dose-dependence of the severity of AH on the receivedradiation dose has not been established. The easier course of hypertension in ATO/CFO servicemen compared to ARSremote servicemen and group 2 PLCChC servicemen can be explained by their younger age at the time of the surveyand less time after exposure to extreme military service factors. In the military in the remote period after exposureto a complex of factors of radiation accidents, the frequency of diagnosing diseases by individual organs and bodysystem increases comparing to non-irradiated servicemen. The total number of disease severity scores on the cumu-lative scale of CIRS diseases is also higher. However, a dose-dependent effect of the severity of comorbid patholo-gy was also not found. These data indicate a higher prevalence of comorbid pathology in servicemen affected by acomplex of factors of radiation accf5idents, compared with participants in the anti-terrorist operation / environ-mental protection. However, the lower severity of comorbid pathology in ATO/CFO participants can also be explainedby their younger age at the time of the survey and less time after exposure to extreme factors of military service. CONCLUSIONS: For servicemen, with increasing time after participation in the elimination of the consequences ofradiation accidents, the course of hypertension without its dose dependence becomes more difficult. The total num-ber of disease severity scores on the cumulative scale of CIRS diseases in servicemen in the remote period after participation in the elimination of the consequences of radiation accidents is higher than in non-irradiated service-men. However, a dose-dependent effect of the severity of comorbid pathology was also not found.
