The paper deals with studies of the intestinal microflora in 114 patients with acne vulgaris (94 and 20 with its papulopustular and nodulocystic forms). Sixty-one (54%) patients have either the first (21%) or second (78.7%) impaired bacterial microflora. At the same time, there are no great differences in the content of the intestinal microflora in different forms of acne. It is noted that adding intestinal microflora-correcting agents to combined therapy in patients with papulopustular acne vulgaris and verified dysbacteriosis reduces the duration of treatment by over twice and makes its duration the same as that in patients without dysbacteriosis.
