Background: Mesenchymal dysplasias or inherited connective tissue diseases are the group of diseases with deficiency of various components of connective tissue. Connective tissue disorders can affect different organs: skeleton, sight organ, skin, lungs, heart. But the most dangerous is vascular wall insufficiency leading to high risk of hemorrhage, especially during pregnancy and delivery due to hemodynamic and hormonal effects on the walls of the modified vessels. Aim: To evaluate the risk of complications during the pregnancy and delivery in patients with mesenchymal dysplasias. Study design: Fifty-six pregnancies in patients with mesenchymal dysplasias, including subclinical forms of diseases: 23 with Marfan syndrome (I group), 22 with Ehlers–Danlos syndrome (II group), and 11 with Osler–Weber–Rendu syndrome (hereditary hemorrhagic telangiectasia) (III group) of the age from 18 to 36. The study included retrospective analysis (for the period from 1993 to 2005) and prospective study. Results of study showed high risk of life-threatening complications during pregnancy and delivery, especially the risk of hemorrhage and cardiovascular complications. In all the patients, we observed the progression of bleeding or development of bleeding in new localizations (epistaxis in 27 patients, easy brushing in 22, skin and mucosa telangiectasia in 20, gastrointestinal bleedings in 4, hemoptysis in 4, hematomas for minor traumas in 14, conjunctivas hemorrhages in 5). Conclusion: The pathogenesis of bleeding in such patients has mixed pattern: besides vascular wall pathology coagulation deficiency plays some role. The preferred delivery method for such patients is caesarean section. Deep vaginal ruptures and serious hemorrhage accompany vaginal delivery.

The objective of this article is to attract the attention of clinical physicians to the rare but extremely relevant clinical pathology of mesenchymal dysplasias (Marfan syndrome, Ehlers–Danlos syndrome, hereditary hemorrhagic telangiectasia) and especially specific characteristics of such diseases during pregnancy. Connective tissue pathology can cover different organs and systems, symptoms of the same disease can vary in different patients thus making diagnostics significantly difficult. Here clinical diagnostic criteria and methods of molecular diagnostics of diseases are described. The pathogenesis of mesenchymal dysplasias is not currently well understood. For the patients with mesenchymal dysplasias pregnancy is fraught with high risk of life-threatening complications. The preferred delivery method for such patients is caesarean section.

Study of pancreatitis remains a topical theme also for the paediatric cohort, especially taking into account practically similar morbidity rates in adults and children. The review presents information and analyzes main genetic risk factors of the development of pancreatitis. Mutations and polymorphisms of the CFTR, CTRC, SPINK1, CPA1, PRSS1, PRSS2 genes that are significant for functioning of the pancreas are discussed in detail. Examples of genetic variants associated with increased or decreased risks of developing disease are given. Special attention is paid to difficulties of interpreting the results of molecular-genetic testing associated with certain gene homology, presence of pseudogenes and disease cases conditioned by spontaneous mutation. Detection of genetic risk factors of chronic pancreatitis allows to early prevent the development of disease in the proband’s relatives, and also to take a more personalized approach to the patient’s treatment.

Moreover, there are signs of their common pathogenesis: a number of proteins, such as PAI-1, play an important role in the pathogenesis of both conditions, as well as in the development of infertility in patients with HT and uCTD Objective — to determine the morphological substrate and molecular mechanisms of impaired pregnancy outcomes in women with uCTD and HT. Subject and methods. A study group included 130 reproductive-aged female patients with primary infertility and a control group consisted of 11 patients (surrogate mothers). An endometrial pipelle biopsy sample was taken from each patient on days 6—8 after ovulation according to the ultrasound findings. The study group patients were divided into subgroups: 1A) infertility and HT (n=91); 1B) infertility, NT, and uCTD (n=19); 1C) infertility and uCTD (n=20). The investigators examined obstetric/gynecological history data, determined the levels of PAI-1 and homocysteine in the blood samples of patients in the subgroups with HT (1A and 1B); assessed the results of the methionine test, and identified the polymorphism or mutations of the following genes: FII, FV (Leiden), FVII, FXII, FXIII, GpIa, GpIb (-5), GpIb (T145M), GpIIIa, PAI-1, FBGb, MTHFR, MTRR, MTR, SLC19A1, angiotensin gene (M235T and T145M), angiotensin-converting enzyme, and their homo-or heterozygosity. Endometrial morphological and immunohistochemical examinations were carried out using primary antibodies to sex hormone receptors, LIF, PAI-1, and osteopontin. Results. The number of pregnancies in the study group was comparable to the number of patients in each subgroup. Childbirth was considered to be a favorable pregnancy outcome; missed miscarriage was an unfavorable one. There were the most favorable outcomes in Subgroup 1C with uCTD and the least one in Subgroup 1B. Comparison of hemostatic system indicators revealed statistically significant differences only in the incidence of disaggregated thrombopathy (88% in Group 1B and 55% in Group 1A). In the endometrium of the study group, there was delayed maturation; sclerotic foci and dyscirculatory disorders were more frequent in the stroma. Conclusion. In HT, uCTD, and, to a greater extent, its concurrence, a genetically determined predisposition to impaired implantation develops due to genetically determined endometrial remodeling that leads to infertility and impaired pregnancy outcomes.
