Insights
Immunotherapy effectively treated recurrent respiratory tract infections in children by boosting T cells. Treatments like TFX and Levamisol showed the most positive results, improving immune function.
Area of Science:
- Pediatrics
- Immunology
- Infectious Diseases
Background:
- Recurrent respiratory tract infections (RRTIs) in children are often linked to depressed T lymphocyte counts, similar to conditions seen in AIDS patients.
- Elevated serum IgM concentrations were also observed in affected children.
Purpose of the Study:
- To evaluate the effectiveness of various immunotherapies in managing RRTIs in children.
- To assess changes in immunologic parameters following different treatment modalities.
Main Methods:
- A study involving 117 children aged 12 months to 10 years with RRTIs.
- Treatment groups received TFX, Levamisol, Broncho-Vaxom, PADMA, or climatotherapy; a control group received no immunostimulants.
- Immunologic parameters, including T lymphocyte counts and serum IgM, were monitored.
Main Results:
- All investigated treatments demonstrated beneficial effects on RRTIs.
- TFX and Levamisol yielded the highest percentage of positive outcomes.
- An increase in T cells percentage was observed across all treatment groups, most notably with Levamisol.
Conclusions:
- Immunotherapies, particularly TFX and Levamisol, are effective in treating RRTIs in children.
- While T cell percentages increased with treatment, no direct correlation was found between T cell numbers and clinical improvement.
Abstract:
Selected immunologic parameters and effectivity of immunotherapy was evaluated in 117 children (12-month-10-year-1-old) suffering from recurrent respiratory tract infections. All the children displayed a profound depression of T lymphocytes number, which resemble the situation seen in AIDS patients. An increase of serum IgM concentration was also noted. Immunotherapy included treatment with the following preparations: TFX and Levamisol which stimulate T cell functions, Broncho-Vaxom which stimulates specific antibody production and a complex herb preparation PADMA showing undefined general stimulatory activity. Separate group of children was subjected to climatotherapy in Czerniawa Sanatorium and received no immunostimulants. All methods of treatment employed had beneficial effect. The highest percentage of positive results was obtained in children receiving TFX and Levamisol. In all groups under study, an elevation of T cells percentage was observed. This was especially evident in Levamisol treated patients. There was no correlation, however, between T cells number and clinical improvement.
