Minimally Invasive Treatment of Benign Thyroid Nodules

Background. Nodular goitre is the commonest pathology of thyroid gland. According to published evidence, the endemic prevalence of iodine deficiency varies within 19–76 % population. The high rates and lack of symptoms at progressive nodules growth warrant the development of effective organ-preserving treatments. Imaging techniques for local precision targeting of individual lesions enable maximum-preserving interventions at thyroid tissue. Today’s world experience of percutaneous ethanol sclerotherapy and radiofrequency ablation is adequate. However, there exist no clear indications for sclerotherapy and radiofrequency ablation, and their consecutive use has not been assessed.Materials and methods. We analyse minimally invasive organ-preserving treatments of benign thyroid nodules (ethanol sclerotherapy, RFA) in 63 patients at the outpatient and general surgery units of BSMU Clinic and MEGI Medical Centre, Ufa, during February 2019 — December 2020.Results and discussion. Ethanol sclerotherapy was highly effective in 46.5 % patients, as evident from discontinued nodule’s blood supply in CDI and B-mode ultrasound, which remained stable in 10.5 % and restored after 3–4 weeks in 25 % patients. Sclerotherapy in colloid goitre was efficient only in 37.5 % patients. Ethanol sclerotherapy was RFA-followed in 25.4 % patients. RFA was favoured at a low-effective sclerotherapy providing for a weak positive dynamics of nodule size, local parietal blood flow preservation and intranodular vessels recanalisation at re-examination.Conclusion. Sclerotherapy was high-effective in cystic nodules. Radiofrequency ablation can be considered most adequate for treating solid nodules. RFA-followed sclerotherapy is a rational choice in treatment of large cystic nodules (>5 cm3 )

Changes of the inflammatory activity and fibrosis in patients with alcoholic liver cirrhosis after autologous hematopoietic stem cell transplantation

Evaluation of treatment results of chronic liver diseases should be made on the basis of morphological analysis of liver biopsies. The aim of our study was to investigate the effect of autologous hematopoietic stem cell transplantation on histology activity index and grade of fibrosis in alcoholic liver cirrhosis patients. The study was performed on liver biopsies of 11 patients with alcoholic liver cirrhosis. Biopsies were taken before the injection of autologous peripheral blood stem cells into celiac trunk, 3 and 12 months after the procedure. Liver biopsy specimens were stained with hematoxylin-eosin and Van Gieson's. Results showed improvement of liver structure and decrease in histology activity index in liver biopsies performed 3 and 12 months after transplantation. Our data suggest that autologous transplantation of hematopoietic stem cell in patients with alcoholic liver cirrhosis is effective method that is capable to reduce inflammation activity in the liver, improve its structure and decrease liver fibrogenesis

Встречаемость йододефицита в  эндемических регионах варьирует, по литературным данным, от 19  до 76  % населения. Высокая распространенность, бессимптомное течение с прогрессирующим ростом узлов диктуют необходимость выработки эффективных органосохраняющих методов лечения. Имея визуализирующие способы локального прецизионного воздействия на отдельные патологически измененные структуры, можно выполнять вмешательства с максимальным сохранением неизмененной ткани щитовидной железы. На сегодня в мире уже накоплен достаточный опыт применения чрескожной склеротерапии этанолом и радиочастотной абляции (РЧА). Однако не разработаны четкие показания к применению склеротерапии и радиочастотной абляции и не оценена возможность последовательного их применения.Материалы и методы. В работе представлен анализ лечения доброкачественных узлов щитовидной железы мини-инвазивными органосохраняющими методами (этаноловая склеротерапия, РЧА) у 63 пациентов, проведенными на базе амбулаторного отделения и отделения общей хирургии Клиники Башкирского государственного медицинского института и медицинского центра «МЕГИ», г. Уфа, в период с февраля 2019 до декабря 2020 г.Результаты и обсуждение. Применение этаноловой склеротерапии было высокоэффективным у  46,5  % пациентов, оценку проводили по нарушению питания узла в виде исчезновения кровотока при УЗД исследовании в режиме ЦДК и B-flow, которое отмечалось в 10,5 % случаев — стабильное и в 25 % отмечено восстановление кровотока спустя 3–4 недели. При склеротерапии узлов с признаками организации коллоида эффективность отмечена только у 37,5 % пациентов. У 25,4 % исследуемых после этаноловой склеротерапии была проведена последующая РЧА. Решение в пользу РЧА было принято при малоэффективном курсе склеротерапии в виде слабой положительной динамики размеров узла, сохранения пристеночных локусов кровотока и реканализации внутринодулярных сосудов при повторном осмотре.Заключение. Высокая эффективность склерозирующей терапии отмечалась при кистозном характере узла. В лечении узлов, имеющих солидный характер, лучшим методом следует признать радиочастотную деструкцию. При лечении кистозно-трансформированных узлов больших размеров (более 5 см3 ) рационально проведение сеансов склеротерапии перед РЧА.

First-in-class humanized FSH blocking antibody targets bone and fat

Blocking the action of FSH genetically or pharmacologically in mice reduces body fat, lowers serum cholesterol, and increases bone mass, making an anti-FSH agent a potential therapeutic for three global epidemics: obesity, osteoporosis, and hypercholesterolemia. Here, we report the generation, structure, and function of a first-in-class, fully humanized, epitope-specific FSH blocking antibody with a KD of 7 nM. Protein thermal shift, molecular dynamics, and fine mapping of the FSH-FSH receptor interface confirm stable binding of the Fab domain to two of five receptor-interacting residues of the FSHβ subunit, which is sufficient to block its interaction with the FSH receptor. In doing so, the humanized antibody profoundly inhibited FSH action in cell-based assays, a prelude to further preclinical and clinical testing
