Abstract.Patients with condyloma acuminata (CA) during pregnancy represent a special risk group. The outcomes of many treatment methods for such cases are not satisfactory. The purpose of the present study was to evaluate the treatment outcome and safety of cryotherapy combined with proanthocyanidins (PCs) for CA in pregnant women. In this study, 46 pregnant women with CA were treated with cryotherapy combined with PCs. The lesions were sprayed with liquid nitrogen until the color of the wart changed from flesh colored to purple. A PC-containing formulation was then sprayed onto a non-woven fabric or single-layer gauze and applied to the affected area. The PC treatment was applied for 20 min, 2 or 3 times per day. All patients were followed up at 1 and 3 months. No visible warts remained after the cryotherapy and PC treatment. At the 1-month follow-up, only 1 case of recurrence was identified. At 3 months, 5 cases of recurrence were identified, and the recurrence rate was 10.9%. The satisfaction rate of the patients was 94% at 1 month and 87% at 3 months after treatment. All pregnancies resulted in healthy live births without delivery complications. Cryotherapy combined with PCs is indicated to be a safe and effective procedure and may serve as a treatment option for pregnant women with CA. IntroductionCondyloma acuminata (CA) are symptomatic genital lesions caused by human papilloma virus (HPV). Patients who have CA during pregnancy are a particular risk group. During pregnancy, vaginal secretions contacting the skin and mucous membranes are more abundant (1), meaning that the vulva will remain in a moist and immersed state, which would be problematic for CA patients. Several factors associated with pregnancy can promote the growth of HPV-induced lesions, for example, pregnancy hormones and reduced immunoresponsiveness. Cases of CA in pregnancy are normally characterized by fast-growing warts, and a reduced tolerance and poor compliance to treatment (2).Only a small number of treatments have been tested and recommended in pregnancy; at present, bi-and tri-chloroacetic acid (BCA/TCA), cryotherapy, electrocautery and surgical excision, including laser treatment, are the only recommended treatments. In addition to high recurrence rates, significant side effects have been observed for these methods, including local ulceration and scar formation, which may reduce a patient's compliance with treatment requirements (3). Moreover, medicine could potentially cause fetal malformation and laser treatment and surgical excision may cause uterine contraction, or even abortion (1,4).Cryotherapy is widely used for the treatment of CA. During the cryotherapy procedure, liquid nitrogen freezes the tissue and thereby causes necrosis; the treatment also stimulates specific immune responses, such as an immunomodulatory action of T lymphocytes against the remaining viable wart tissue (5,6). The advantages of cryotherapy are that it is simple, inexpensive, rarely causes scarring or depigmentation, and is safe for use in pregnancy.Pro...

Atopic dermatitis (AD) and psoriasis are both chronic recurrent inflammatory skin diseases. However, research on AD and psoriasis co-morbidity is still in early stages and limited to clinical manifestations. In this study, we studied the role of autophagy-related genes in AD and psoriasis by used integrated bioinformatics methods. We obtained differentially expressed genes (DEGs) for psoriasis and AD by analyzing the datasets GSE14905(psoriasis) and GSE32924(atopic dermatitis). We further identified autophagy-related DEGs by intersecting above-obtained DEGs with autophagy-related genes. Then we performed Gene Ontology (GO), Kyoto Encyclopedia Genes and Genomes (KEGG) and Gene Set Enrichment Analysis (GSEA). And hub genes were identified by constructing protein-protein interaction (PPI) networks. Finally, we conducted ROC validation of hub genes and explored the correlation of hub genes with other molecules and immune cells in atopic dermatitis and psoriasis. Finally, we concluded that the 13 autophagy-related genes are involved in the pathogenesis and progression of AD and psoriasis by regulating cell cycle, cellular components eradication and drug metabolisms, and could predict the onset and severity of diseases.
