Analysis of the development dynamics of cough syndrome in acute nasopharyngitis with intoxication syndrome

Abstract

Introduction. Although acute cough in acute inflammatory diseases of the upper respiratory tract seems to be a minor problem and can be stopped on its own, it holds the leading position among all reasons for population receiving health care due to significant decrease in life quality.Purpose. To analyze the cough severity in patients with acute nasopharyngitis with intoxication syndrome in the treatment of systemic non-steroidal anti-inflammatory drugs (NSAIDs) and local interferon therapy.Materials and methods. The study included 62 patients with acute nasopharyngitis with intoxication syndrome, in the period from the onset of the first symptoms to the visit to the doctor was no more than 24 hours. They were divided into 2 groups: group 1 − 32 people (14 men, 18 women, age 34.4 ± 10.3 years) received traditional systemic therapy with NSAIDs, group 2 − 30 people (13 men, 17 women, age 41.1 ± 13.7 years) received interferon-α2b intranasally. Cough severity was assessed using a 3-point visual analog scale (VAS) on the day of admission and for the next 7 days.Results. On the 1st day dry cough was observed in 62.5–63.3% of cases. Starting from the 3rd day of observation, there were statistically significant differences in the intensity of this symptom between the groups. In the traditional therapy of NSAIDs, an increase in the number of patients with a complaint of cough, and an increase in its severity compared with the first day of observation was revealed. They lasted until the 6th day of illness, which was explained by the spread of the inflammatory process to the trachea and bronchi. In the treatment of local interferon therapy, cough regression was noted on day 4 in 83.3% of cases, with its complete disappearance in this group on day 6. The total duration of cough in group 1 was 6.0 (5.0; 8.0) days, in group 2 – 2.0 (1.0; 3.0) days.Conclusion. In acute inflammatory diseases of the upper respiratory tract, cough in the absence of prescribing drugs that affect this symptom persists on the eighth day of observation in 56.2% of patients with traditional therapy with systemic NSAIDs.
