Psoriatic onychodystrophy is quite common in patients with psoriasis. Changes in psoriatic nails have a wide range of clinical manifestations, including symptoms of damage of the nail bed and/or nail matrix. The article presents information about clinical and pathological manifestations of psoriatic onychodystrophy, the mechanisms of formation of pathological changes. The existence of the relationship between the change of nail plates in patients with psoriasis and the development of psoriatic arthritis is explained, the prognostic value of individual symptoms is analyzed. The diagnostic criteria for the histological diagnosis of psoriatic onychodystrophy are described. The information about the occurrence of each symptom in patients with psoriasis with dystrophic nail changes is given.

Psoriatic arthritis (PsA) is a chronic immune-mediated disease from a group of spondyloarthritis, which is characterized by damage to the musculoskeletal system with a wide range of different clinical manifestations and is usually associated with psoriasis. Activation of the interleukin (IL) 23/IL17 axis plays a key role in the pathogenesis of PsA and psoriasis. When non-steroidal and synthetic disease-modifying antirheumatic drugs are insufficiently effective, biological drugs are recommended. In recent years, there have been considerable advances in PsA treatment with tumor necrosis factor-α (IFN-α) inhibitors and IL-12/23 inhibitors. However, in some cases, this therapy fails to provide the desired effect and a search for new treatments for PsA seems to be an urgent task. The paper desctibes a clinical case demonstrating the efficacy of the IL17A inhibitor ixekizumab in a patient with high PsA activity and recurrent uveitis in both eyes. Ixekizumab therapy resulted in positive changes as the reduced severity of articular syndrome and psoriasis and normalization of acute phase parameters. Assessing the activity of PsA over time when using ixekizumab during a year showed an average decrease in ESR from 72 to 19 mm/h, in CRP from 162.1 to 0 mg/L, BSA from 51 to 0.25%, PASI from 43. 6 to 0, DAPSA from 78.2 to 2, ASDAS-SRB from 5.11 to 1.12, BASDAI from 4.85 to 1, BASFI from 5.3 to 0.7, BASMI from 5.0 to 2.6, MASES from 6 to 0, LEI from 2 to 0, SPARCC from 6 to 0, and NAPSI from 28 to 8. Thus, this clinical case is an example of successful treatment with the IL17 inhibitor ixekizumab for PsA with recurrent uveitis in the patient who has previously received three drugs from the TNFα group without any effect.

Methods: We reviewed retrospectively the charts of psoriatic arthritis patients who died from 1995-2010.We included 13 deceased patients with a psoriatic arthritis di-agnosis and compared them with 140 patients living with psoriatic arthritis that at-tend the same clinic. The population was derived from a single academic rheumatol-ogist’s practice in St. John’s, Newfoundland, Canada. Patients are seen at six-month intervals with a history and physical exam performed at each visit. Laboratory data was collected at each visit. Diagnosis of psoriatic arthritis is based on the CASPAR Classifcation and Diagnostic Criteria for Psoriatic Arthritis. Results: The mean age of the 13 deceased patients was 62.9 years. Of these, 38.5% were female and 85.7% had an erythrocyte sedimentation rate greater than 15 mm/hour vs. 36.4% of patients living with psoriatic arthritis. Of deceased patients, 16%had dystrophic nail changes of vs. 59.6% of living patients. Health Assessment Questionnaire was found to show a signifcantly greater loss in function in deceasedpatients. (1.39 vs. 0.70, p= 0.002). Almost half of the deceased patients had used Prednisone (46.2%) as opposed to 11.2% of living patients. Conclusions: We realize that this study employs a small sample size. Increased ESR and Health Assessment Questionnaire score were found to be associated with mor-tality in psoriatic arthritis patients. Dystrophic nail changes were found to be pro-tective for psoriatic arthritis patients.

Dystrophic nail changes without a skin lesion is a rare form of psoriasis. We describe a patient that presented with a chronic nail onychomycosis and a destructive thumb interphalangeal joint which was initially considered as onychomycotic joint infection, and was later diagnosed as having dystrophic nail changes in psoriatic arthritis and coexistent onychomycosis. The nail changes were completely normalized after methotrexate treatment.

Background: Nail changes are common in psoriatic arthritis (PsA), with varying relationships existing between skin, nail, and joint disease. Objective: To further characterize relationships between nail changes, psoriasis, and joint involvement in PsA patients. Methods: One hundred eighty-eight PsA patients had skin, fingernail, and rheumatological assessments completed. Hand and fingernail photographs were taken and reviewed by a dermatologist. Results: Higher swollen joint counts were associated with distal interphalangeal (DIP)/periungual psoriasis ( P = .001), more splinter hemorrhages ( P = .006), and any nail bed change ( P = .03). Higher tender joint counts were associated with rough onychorrhexis ( P < .001), DIP/periungual psoriasis ( P = .03), red lunula ( P = .001), nail crumbling ( P = .046), any nail matrix ( P = .03), and nail bed change ( P = .03). Joint involvement was associated with same-digit nail changes; strongest association was swollen or tender DIP with subungual hyperkeratosis, odds ratio = 26.6 (95% CI, 5.1-139.1). Conclusion: The DIP/periungual psoriasis and specific nail changes were associated with higher joint counts and certain nail changes with same-digit joint involvement.

The role of monetary factor in generating inflationary processes in Russia has stimulated various debates in social and scientific circles for a relatively long time. The authors show that identification of the specificity of relationship between money and inflation requires a complex approach based on statistical modeling and involving a wide range of indicators relevant for the price changes in the economy. As a result a model of inflation for Russia implying the decomposition of inflation dynamics into demand-side and supply-side factors is suggested. The main conclusion drawn is that during the recent years the volume of inflationary pressures in the Russian economy has been determined by the deviation of money supply from money demand, rather than by money supply alone. At the same time, monetary factor has a long-run spread over time impact on inflation.

Проведено исследование гена интерферон индуцированного трансмембранного белка 5 (IFITM5) у 99 пациентов с несовершенным остеогенезом (НО) из 86 неродственных семей. НО - клинически и генетически гетерогенное наследственное заболевание соединительной ткани, основное клиническое проявление которого - множественные переломы, начиная с неонатального периода жизни, зачастую приводящие к инвалидизации с детского возраста. К основным клиническим признакам НО относятся голубые склеры, потеря слуха, аномалия дентина, повышенная ломкость костей, нарушения роста и осанки с развитием характерных инвалидизирующих деформаций костей и сопутствующих проблем, включающих дыхательные, неврологические, сердечные, почечные нарушения. НО встречается как у мужчин, так и у женщин. До сих пор не определена степень генетической гетерогенности заболевания. На сегодняшний день известно 20 генов, вовлеченных в патогенез НО, и исследователи разных стран продолжают искать новые гены. В последнее десятилетие стало известно, что аутосомно-рецессивные, аутосомно-доминантные и Х-сцепленные мутации в широком спектре генов, кодирующих белки, которые участвуют в синтезе коллагена I типа, его процессинге, секреции и посттрансляционной модификации, а также в белках, которые регулируют дифференцировку и активность костеобразующих клеток, вызывают НО. Мутации в гене IFITM5, также называемом BRIL (bone-restricted IFITM-like protein), участвующем в формировании остеобластов, приводят к развитию НО типа V. До 5% пациентов имеют НО типа V, который характеризуется образованием гиперпластического каллуса после переломов, кальцификацией межкостной мембраны предплечья и сетчатым рисунком ламелирования, наблюдаемого при гистологическом исследовании кости. В 2012 г. гетерозиготная мутация (c.-14C> T) в 5’-нетранслируемой области (UTR) гена IFITM5 была идентифицирована как основная причина НО V типа. В представленной работе проведен анализ гена IFITM5 и идентифицирована мутация c.-14C>T, возникшая de novo, у одного пациента с НО, которому впоследствии был установлен V тип заболевания. Также выявлены три известных полиморфных варианта: rs57285449; c.80G>C (p.Gly27Ala) и rs2293745; c.187-45C>T и rs755971385 c.279G>A (p.Thr93=) и один ранее не описанный вариант: c.128G>A (p.Ser43Asn) AGC>AAC (S/D), которые не являются патогенными. В статье уделяется внимание особенностям клинических проявлений НО V типа и рекомендуется определение мутации c.-14C>T в гене IFITM5 при подозрении на данную форму заболевания. A study was made of interferon-induced transmembrane protein 5 gene (IFITM5) in 99 patients with osteogenesis imperfecta (OI) from 86 unrelated families and a search for pathogenic gene variants involved in the formation of the disease phenotype. OI is a clinically and genetically heterogeneous hereditary disease of the connective tissue, the main clinical manifestation of which is multiple fractures, starting from the natal period of life, often leading to disability from childhood. The main clinical signs of OI include blue sclera, hearing loss, anomaly of dentin, increased fragility of bones, impaired growth and posture, with the development of characteristic disabling bone deformities and associated problems, including respiratory, neurological, cardiac, and renal disorders. OI occurs in both men and women. The degree of genetic heterogeneity of the disease has not yet been determined. To date, 20 genes are known to be involved in the pathogenesis of OI, and researchers from different countries continue to search for new genes. In the last decade, it has become known that autosomal recessive, autosomal dominant and X-linked mutations in a wide range of genes encoding proteins that are involved in the synthesis of type I collagen, its processing, secretion and post-translational modification, as well as in proteins that regulate the differentiation and activity of bone-forming cells cause OI. Mutations in the IFITM5 gene, also called BRIL (bone-restricted IFITM-like protein), involved in the formation of osteoblasts, lead to the development of OI type V. Up to 5% of patients have OI type V, which is characterized by the formation of a hyperplastic callus after fractures, calcification of the interosseous membrane of the forearm, and a mesh lamellar pattern observed during histological examination of the bone. In 2012, a heterozygous mutation (c.-14C> T) in the 5’-untranslated region (UTR) of the IFITM5 gene was identified as the main cause of OI type V. In the present work, the IFITM5 gene was analyzed and the de novo c.-14C> T mutation was identified in one patient with OI who was subsequently diagnosed with type V of the disease. Three known polymorphic variants were also identified: rs57285449; c.80G> C (p.Gly27Ala) and rs2293745; c.187-45C> T and rs755971385 c.279G> A (p.Thr93 =) and one previously undescribed variant: c.128G> A (p.Ser43Asn) AGC> AAC (S / D), which were not pathogenic. The article focuses on the features of the clinical manifestations of OI type V, and it is recommended to determine the c.-14C> T mutation in the IFITM5 gene if this form of the disease is suspected.

Introduction: Viral encephalitis accounts for 40-70% of all cases worldwide, central nervous system infections pose a diagnostic challenge because clinical manifestations are not typically pathognomonic for specific pathogens, and a wide range of agents can be causative. The aim: To assess the diagnostic value of intrathecal synthesis of specific antibodies in patients with inflammatory lesions of the central nervous system. Materials and methods: Within the framework of the study, two groups of 90 people in each were formed from the patients with neuroinfections admitted to our Center. Intrathecal synthesis (ITS) of total (unspecific) IgG in members of one of group (group of compare) was determined. Brain synthesis of specific antibodies (Ab) to some neurotropic pathogens (herpes simplex virus 1/2, cytomegalovirus, Epstein-Barr virus, varicella zoster virus, rubella virus, Borrelies) was studied in the second group of patients (group of interest). There were no statistically significant differences between groups by gender and age. Encephalitis and encephalomyelitis prevailed among patients of both groups Results: ITS of total IgG was established in 30 (33.3 ± 6.1 %) patients of the first group with IgG index more than 0.6 indicating on inflammatory process in CNS and no marked changes of CSF. ITS of specific Ab was determined in 23 of 90 (25.6 ± 4.6 %) patients included into group of interest. In more than half of cases Ab to several infectious agents were detected simultaneously. ITS of various specificity, in particular, to measles and rubella viruses, and VZV, known as MRZ-reaction, is characteristic of some autoimmune lesions of CNS, multiple sclerosis first of all. In fact, further research of 5 patients with MRZ-reaction confirmed their autoimmune failure of CNS. Detection of ITS in the CSF samples didn’t depend on concentration of specific Ab in serum and CSF and wasn’t followed by HEB dysfunctions which were observed with the same frequency in patients with or without ITS (13.0 % and 13.6 % respectively). Conclusion: Specific Ab synthesis to several neurotropic pathogens in the CSF of significant part of examined patients was established. Thus, diagnostic value of ITS of specific immunoglobulins seems to be limited to cases in which autoimmune damage of the CNS is suspected.
