Objective. Determination of morphological features of skin lesions in patients with widespread psoriasis, study of the level of expression of immunohistochemical markers of vascularization.
Materials and methods. 80 patients with psoriasis were under observation. The control group consisted of 20 practically healthy people (control group) of the same age. All patients underwent a skin biopsy with a histological evaluation of the biopsy material to determine the form and severity of the course of psoriasis in accordance with the requirements of the morphological section of the modern classification.
Results and discussion. Applying the scale of intensity of skin vascularization according to Amin M.M. et. al. (2012), it was detected that damaged dermal areas due to psoriasis, on average, had 17.25±5.34 micro vessels at magnification (×400), which corresponds to the level of moderate vascularization (11-20 capillaries). Normal skin in control group had mean index 4.32±2.01 at (×400) at the level of weak vascularization (4-10 capillaries), which statistically reliably differs from general group (р˂0.05). Analysis of the condition of vascular bed at different levels of severity of psoriasis course showed that a number of cells at moderate degree of severity (22.65±5.87) was considerably higher than at mild psoriasis (10.09±3.22), and even more numerous than in CG (4.32±2.01). Statistically reliably both groups differ between them (р<0.05), and with CG (р<0.05). According to Fisher’s exact test, distribution of absolute meanings of monitoring of intensity of cytoplasmic staining with VEGF marker in all groups between them had a reliable difference (р<0.05). We detected a moderate correlation connection between increased intensity of VEGF expression and amplification of the severity of psoriasis course (r=+0.430). According to Fisher’s exact test, distribution of monitoring of intensity of cytoplasmic staining with MMP-9 marker in all groups between them had a reliable difference (р<0.05); a moderate correlation connection between increased intensity of MMP-9 marker expression and amplification of the severity of psoriasis course was detected (r=+0.532).
Conclusions. The results of conducted clinical, morphological and immunohistochemical investigations enable to consider importance of neoangiogenesis processes in pathogenesis of this dermatosis and need in elaboration of therapeutic measures with direct influence on this aspect of pathogenesis.
Key words: psoriasis, immunity, neoangiogenesis.

Introduction. Acne is one of the most common dermatological diseases. It may have a chronic course, leaving permanent marks, and in last years has been tending to have more and more severe clinical course with widespread skin lesions. According to recent studies, the development of acne is due to the combined effect of endogenous and exogenous factors, among which endocrine diseases, disorders of metabolic processes, reduced systemic immunity and phagocytic ability of mononuclear phagocytes and granulocytes at various stages of phagocytosis of pyogenic cocci, which contributes to more severe clinical course, and frequent relapse of this diseases. It was also proved that the intestinal microbiota plays an important role in the formation of homeostasis and immune response. The Objective of the study is to determine the evolution of phagocytosis indices in patients with acne under different comprehensive treatments, using oral antibiotics, immunotherapy (PRPtherapy), probiotics, low-dose birth control pills and IPL- therapy.
Materials and methods. We observed 93 women with acne aged from 18 to 25 years old. In 19 (20.43%) patient mild acne was diagnosed, in 41 (44.09%) – moderate acne, in 33 (35.48%) persons – severe acne, 54 (58.06%) persons suffered from acne up to 1 year, 39 (41.93%) – from 1 to 3 years. To assess the state of phagocytosis in patients with acne vulgaris, we determined phagocytic activity (PA) and phagocytic index (PI) of polymorphonuclear leukocytes, nitro blue tetrazolium recovery test (NBT test spontaneous) and NBT-test pyrogenal stimulated by recognized methods.
Results. Analysis of the studied parameters of phagocytosis at the end of treatment showed a significant increase in patients of the core group who were administered a comprehensive treatment which included oral antibiotic, probiotic, and low-dose birth control pills, PRP-therapy and IPLtherapy, as compared with the patients of other groups under study.
Conclusions. Using combined therapy for women with acne occurring against the backdrop of a sluggish process of phagocytosis and concomittant intestinal dysbiosis leads to normalization of the leading indices of phagocytosis (PI, PA, NBT tests both spontaneous and stimulated), and enchances their phagocytic activity both during capture and formation of bactericidal activity and in the final stages of phagocytosis justifying the feasibility of a combined use of antibiotics, probiotic, low-dose birth control pills PRP-therapy and IPL-therapy in the treatment of acne.
