About this study

Official title: Bacteriophage Therapy in Acute Tonsillitis

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.

Read the detailed description

Comprehensive outpatient treatment was based on standard clinical guidelines, and symptomatic treatment was performed. On the first day of diagnosis, patients were prescribed complex antibacterial therapy on the basis of possible causative agents. Subsequently, antibiotic therapy was adjusted based on the results of the bacteriological examinations. A total of 67 patients received 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.

The drug causes lysis of specific bacteria including Staphylococcus, Enterococcus, Streptococcus, enteropathogenic Escherichia coli, Proteus vulgaris, Proteus mirabilis, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Klebsiella oxytoca. The drug is recommended for use for diseases of the ear, throat, nose, respiratory tract and lungs; inflammation of the sinuses and middle ear; tonsillitis; pharyngitis; laryngitis; tracheitis; bronchitis; pneumonia, pleurisy; and other inflammatory diseases. The choice of this drug was based on bacteriological studies.

Being tested
Nebulizer inhalation irrigation of the mucous membranes of the tonsils with a bacteriophage.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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).

    Measured: study of one patient - 4 weeks

  2. 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.

    Measured: study of one patient - 2 weeks

  3. 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.

    Measured: study of one patient - 4 weeks

Secondary outcomes (1)
  1. The second stage of the study (statistical).

    The results will be analyzed using a statistical program based on Excel 2017 (Microsoft Office 2017). Clinical signs will be calculated as a percentage (%) incidence. We will calculate the chi-square (χ2) test or Fisher's exact test (for expected values <5) to assess if certain pairs of microbes are more common than expected by chance in bacteriological examination. In addition, we will use the Kruskal-Wallis test to compare the average delay between disease onset and sample collection between samples containing one or more organisms. When evaluating immunological analyzes, characterizing the statistical significance of differences, the Student's t-test will be used with the definition of the confidence interval. The X-square test will be used to assess the frequency of identifying qualitative features. In all analyzes, P ≤ 0.05 was considered significant.

    Measured: 4 weeks

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical observation of sick children. (time frame: study of one patient - 4 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
