Insights
Recurrent vaginal candidosis may stem from diminished peripheral T lymphocytes. Immunologic treatment with thymopentin can help restore T-helper cells and reduce candidosis relapses.
Area of Science:
- Immunology
- Mycology
- Infectious Diseases
Background:
- Chronic recurrent vaginal candidosis presents therapeutic challenges.
- Investigating immunologic factors is crucial for understanding treatment failures.
Purpose of the Study:
- To identify immunologic factors contributing to chronic recurrent vaginal candidosis.
- To evaluate the efficacy of immunologic treatment for recurrent cases.
Main Methods:
- Studied T lymphocytes and subpopulations in women with acute and chronic vaginal candidosis (Candida albicans and C. glabrata).
- Conducted in vitro T lymphocyte proliferation tests.
- Administered thymopentin to patients with chronic recurrent candidosis and monitored clinical outcomes.
Main Results:
- Women with C. albicans vulvovaginitis had reduced peripheral T lymphocytes compared to healthy controls.
- Non-specific killer (NK) cells were lower in acute C. albicans infections.
- Thymopentin treatment led to recovery in patients with initially low T-helper cells.
Conclusions:
- Diminished peripheral T lymphocytes may be a factor in chronic recurrent C. albicans vaginitis.
- Immunologic treatment, specifically with thymopentin, can decrease relapse rates in these patients.
Objective:
According to unsatisfactory therapeutic results in patients with chronically recurrent vaginal candidosis, we investigated if immunologic patient factors could be found and treated.
Methods:
In 42 women with chronically recurrent and 20 women with acute Candida albicans vulvovaginitis, as well as 14 women with C. glabrata vaginitis, the following investigations were carried out: identification of yeast species; quantification of T lymphocytes and their subpopulations in sera; proliferation tests of T lymphocytes in vitro; treatment of 18 patients with chronically recurrent vaginal candidosis with the synthetic T-lymphocyte- stimulator thymopentin; and, finally, control of the above-mentioned parameters in the clinical course.
Results:
Women with C. albicans vulvovaginitis showed fewer T lymphocytes and subpopulations in the peripheral blood than healthy women. Only the number of non-specific killer (NK) cells, however, was significantly lower in cases of acute C. albicans vulvovaginitis. In women with C. glabrata vaginitis, the number of T lymphocytes in the blood was within the normal range. In vitro proliferation tests using mitogens, bacterial antigens, and commercially available candida antigens with and without addition of thymopentin were carried out on the T lymphocytes of women with chronically recurrent C. albicans vulvovaginitis. These tests revealed no significant differences compared with the other patients with C. albicans infections. The patients were treated with thymopentin. Those women who revealed an increase of initially low numbers of T-helper cells recovered from vaginal candidosis after thymopentin treatment.
Conclusions:
The peripheral T lymphocytes may be diminished in patients with chronically recurrent C. albicans vaginitis, and immunologic treatment can reduce the relapse rate.
