RESUMO

The objective of the present work was to study the influence of allelic variant associations of 1-beta interleukin (C3953T, &511C, T31C), interleukin-6 (C174G), and tumour necrosis factor-alpha (G308A) gene polymorphisms on the serum cytokine level in the patients presenting with chronic suppurative otitis media. A total of 299 patients at the age varying from 16 to 55 years with this condition divided into three groups were examined. Group 1 was comprised of 146 patients suffering from the tubotympanic form of chronic suppurative otitis media (CSOM). Group 2 was composed of 153 patients with epitympanic antral form of this condition. The control group included 183 subjects who have never suffered pathological changes in the middle ear. Human genomic DNA was analyzed with the use of the polymerase chain reaction (PCR). The serum cytokine levels were measured by the solid-state enzyme immunoassay in the beginning and at the end of the treatment period. The study has demonstrated that 56.2% of the healthy residents of the trans-Baikal region had the C/T Il-1b (C3953T) genotype. 79.1% of the patients presenting with the carious carious-destructive form of chronic suppurative otitis media were the heterozygous carriers of the T511C gene of 1-beta interleukin and had the maximally high concentrations of this interleukin in the blood serum. A rise in the production of the pro-inflammatory mediator (IL-6) was found to be related to the severity of the inflammatory process in the middle ear. The TNF-alpha content in the patients with CSOM during the active period of the disease proved to increase by a factor of 6 in comparison with that in the subjects of the control group irrespective of the type of mutation.

RESUMO

We present the results of the surgical treatment of 300 patients presenting with chronic suppurative otitis media. The changes in the mucous membrane of the tympanic cavity were revealed in 61% of the patients with mesotympanitis while spreading cholesteatoma occurred in 48% of the cases of «dry¼ perforations. The cholesteatomic process was documented in 64% of the patients with epitympanitis, the remaining patients presented with the pyo-carious process. The efficiency of the surgical intervention on the «dry¼ ear of the patients with the tubotympanic form of chronic suppurative otitis media (CSOM) amounted to 91.4% compared with 85% in the case of the altered mucous membrane of the tympanic cavity, 85.5% and 92.9% in the patients with the pyo-carious and cholesteatomic forms of the tympano-antral lesions, respectively. Residual cholesteatomas were found in 7.8% of the patients suffering from epitympanitis during the three year follow-up period. It is concluded that the results of clinical and morphological observations taken together with intraoperative findings give reason to consider mesotympanitis to be a prognosticallyunfavourable form of chronic suppurative otitis media.

RESUMO

The objective of the present work was to study the characteristics of middle ear microflora in the patients presenting with chronic suppurative otitis media (CSOM), clarify changes in its species composition over the territory of the Transbaikal Krai during the period from 2000 till 2013, and elucidate its dependence on the treatment prescribed with due regard for sensitivity of microorganisms to medications. The results of 13 year observations of the bacterial contents and resistance of microflora to antibacterial preparations in the middle ear of the patients suffering from CSOM in the Transbaikal Krai are presented.
