NCT04682964

Brief Summary

The patients received bacteriophage therapy with a liquid piobacteriophage complex (liquid pyobacteriophage complex - PCL). PСL was administered via nebulizer inhalation to irrigate the tonsil mucosa. A total of 5 ml of PCL was inhaled for 10 minutes every 5 days. The drug causes the lysis of certain bacteria, including staphylococcus, enterococcus, streptococcus, enteropathogenic E. coli, Proteus vulgaris, Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae and Klebsiella oxytoca. The choice of this drug was based on bacteriological studies.

Outcome Measures

Primary Outcomes (3)

  • Clinical observation of sick children.

    Children with clinically diagnosed acute tonsillitis are examined. The clinical study will be carried out on an outpatient basis in cooperation with the clinic of the Tashkent Pediatric Medical Institute. Prior to the study, written permission will be obtained from the parents or guardians of the children to participate in the study. Investigated: anamnesis of the child, the course of the disease, complaints of parents about the child's condition, body temperature in dynamics, visually - the state of the nasopharynx, the manifestation of clinical symptoms (sore throat, headaches, difficulty swallowing food, aphonia, and other signs) in dynamics, the functional state of internal organs (percussion, palpation and auscultation).

    study of one patient - 4 weeks

  • Laboratory research methods.

    All examined children will undergo general clinical examination and pharyngoscopy. Additionally, all patients will have tonsil swabs for bacteriological examination (bacteriological culture, n x 10⁴/mL ) according to the standard technique. Also, swabs from the nasopharynx will be taken for viral lesions by the standard method - PCR (polymerase chain reaction). The research will be carried out in specialized laboratories.

    study of one patient - 2 weeks

  • Experimental clinical stage. Bacteriophage therapy.

    Comprehensive outpatient treatment will be based on standard clinical guidelines. Patients will be prescribed antibiotic therapy based on possible pathogens. Patients will receive bacteriophage therapy using a liquid pyobacteriophage complex (liquid pyobacteriophage complex - PCL), through nebulizer inhalation to irrigate the mucous membranes of the tonsils. Just 5 ml PCL for 10 minutes once every 5 days. Efficacy will be studied based on immunological studies.A study of cellular (class of T-lymphocytes, Inflammatory cytokines (e.g., IL-1,2,4,5,6,11,13 - U/ml) and TNF-α) and humoral ( IgA / IgM / IgG -IU/mL) immunity in children will be carried out, using (Enzyme Linked Immunosorbent Assay) ELISA which is an immunoassay, suited to the determination of antibodies in the field of infectious serology.

    study of one patient - 4 weeks

Secondary Outcomes (1)

  • The second stage of the study (statistical).

    4 weeks

Study Arms (1)

Nebulizer inhalation bacteriophage therapy

EXPERIMENTAL

To study the effects of bacteriophage therapy on acute tonsillitis in children and adolescents in an outpatient setting.

Drug: Nebulizer inhalation irrigation of the mucous membranes of the tonsils with a bacteriophage.

Interventions

Bacteriophage therapy using a liquid complex of pyobacteriophages (pyobacteriophage complex liquid - PСL). PСL was administered via nebulizer inhalation to irrigate the mucous membranes of the tonsils. In total, 5 ml of PCL was inhaled for up to 10 minutes once every 5 days.

Also known as: Bacteriophage therapy.
