Нарушения микробиоценоза кишечника у больных ВИЧ-инфекцией

Нарушения микробиоценоза кишечника у больных ВИЧ-инфекцией

Abstract

Цель. Оценка нарушений микробиоценоза кишечника у больных ВИЧ-инфекцией. Методы. Проведено микробиологическое исследование образцов кала у 317 пациентов, находящихся на разных стадиях ВИЧ-инфекции: 13 (4,1%) больных — на стадиях острой инфекции (2А, 2B, 2В), 217 (68,5%) — на III стадии, 87 (27,4%) — на стадиях IVА-Б (по классификации Покровского В.И., 2001). Проведено микробиологическое исследование образцов кала путём посева на питательные среды. Результаты. Нарушения микробиоценоза кишечника выявлены у 94% пациентов. Преобладало снижение облигатных микроорганизмов, особенно бифидобактерий (снижение их содержания ниже нормативных показателей отмечено у 70,3% больных). У 57,1% пациентов отмечен избыточный рост условно-патогенных микроорганизмов, лидирующую позицию среди которых занимают S. аureus и грибы рода Candida. Микробный пейзаж кишечника не зависел от клинической стадии ВИЧ-инфекции и наличия оппортунистических инфекций. Единственным признаком, ассоциированным с выраженностью микробиологических нарушений, было низкое количество CD4-лимфоцитов. Вывод. Нарушения микробиоценоза кишечника типичны для больных ВИЧ-инфекцией на всех стадиях заболевания независимо от наличия оппортунистических инфекций; низкое содержание СD4-лимфоцитов ассоциировано с большей выраженностью указанных изменений.

Aim. To assess the changes in intestinal microbiota in patients with HIV. Methods. The cultures of stool samples of 317 patients with different stages of HIV [13 (4.1%) patients — with the acute infection stage (2A, 2B, 2C), 217 (68.5%) — with the stage III, 87 (27.4%) — with the stages IVA-B according to classification by Pokrovsky V.I., 2001] were examined by plating on the growth medium and further microbiologic examination. Results. Changes in intestinal microbiota were found in 94% of the patients. The decrease in the obligatory microorganisms quantity, especially in bifidobacteria (lower than reference ranges in 70.3% of patients) was the most frequent finding. Bacterial overgrowth of conditionally pathogenic biota (mainly S. aureus and Candida) was registered in 57.1% of patients. The intestinal microbiota composition did not depend on the clinical stage of HIV infection and presence of opportunistic infections, with only CD-4 count associated with the degree of intestinal microbiota changes. Conclusion. Intestinal microbiota changes are typical for patients with HIV infection at all stages of the disease regardless of opportunistic infections presence. Low CD-4 count is associated with higher severity of intestinal microbiota changes
