COVID-19 is an infectious disease caused by the beta-coronavirus SARS-CoV-2 that in 2020 has spread worldwide. In most severe patients, the clinical picture begins with respiratory failure further deteriorating up to multiple organ failure. Development of coagulopathy is the most adverse prognostic. Analyzing currently available clinical data revealed that 71.4 % and 0.6 % of survivors and fatal cases, respectively, demonstrated signs of overt disseminated intravascular coagulation (DIC). Monitoring D-dimer level, prothrombin time, platelet count and fibrinogen content is important for determining indications for treatment and hospitalization in COVID-19 patients. In case such parameters deteriorate, a more pro-active “aggressive” intensive care should be applied. Low molecular weight heparin (LMWH) should be administered to all patients with diagnosed COVID-19 infection (including non-critical patients) requiring hospitalization, but having no contraindications to LMWH.
Introduction. Human papillomavirus infection (HPV-infection) remains one of the most important health problems as it significantly reduces the quality of life and stigmatizes the patients. Also, the prevalence of cervical cancer – the most severe outcome of the HPV-infection is 5 % of the global burden of cancer. Although vaccination against human papillomavirus has been proved efficient, its availability in Russia continues to be limited. Therefore, it is important to review other methods of HPV-infection control. A number of studies have confirmed the efficacy of glucosaminylmuramyl dipeptide (GMDP) in the treatment of diseases associated with HPV-infection, but no systematic evaluation of these studies has been published in the available literature.Aim: to analyze the data on the efficacy and safety of GMDP in the treatment of diseases and conditions associated with HPVinfection.Materials and methods. We used the PRISMA approach. The search for the relevant publications was conducted in international scientific databases: the Scientific Electronic Library, the Google Scholar, the ScienceDirect, the Cochrane Community Library, the Pubmed/MEDLINE, and clinical research registries. For this systematic analysis, only full-text publications were used. We evaluated the reliability of evidence and the methodological quality of the studies.Results. We used the following search queries: "glucosaminyl-muramyl dipeptide", "glucosamine L'muramyl dipeptide", "H-acetylglucosaminyl-H-acetylmuramyl dipeptide", "GMDP", "Licopid" (both in Russian and English transcriptions). Based on the results of the screening, 14 full-text publications were selected. At the final stage, review articles with secondary data were excluded; also excluded were original articles published in doubtful resources and those with an unclear status of peer reviewing. This systematic analysis includes 7 publications of acceptable methodological quality. Here, we summarize the consistent conclusions derived from these reports: the addition of therapy with GMDP to local (surgical) methods increases the efficacy of treatment and the duration of remission; destruction of condylomas is more effective when combined with the course of GMDP as compared to using the local destruction alone; GMDP enhances the production of cytokines that have a direct antiviral and antiproliferative effect in HPV-infection (interleukin-1, tumor necrosis factor alpha, gamma-interferon); GMDP causes normalization of cellular and humoral immunity (T-lymphocytes, T-cytotoxic lymphocytes, B-lymphocytes, CD3+, CD4+, CD8+, CD16+, and CD72+ lymphocytes, as well as the production of serum immunoglobulins IgA, IgG, and IgM). A high safety profile of GMDP is evidenced from the absence of reports on adverse events.Discussion. The recommendation for the inclusion of GMDP into a comprehensive treatment for HPV-infection in addition to local interventions is a strong recommendation. The differences between the Russian and international approaches can be explained by the difference in the available resources and funding. We propose to test whether using GMDP for reducing the risk of recurrent HPV-infection is beneficial in terms of pharmacoeconomics. Conclusion. The high efficacy and safety of GMDP in the combined therapy of HPV-infection has been confirmed. Further carefully designed studies on GMDP are needed.
There is a global problem of increment of the number of children with clinical features that mimic Kawasaki Disease (KD) during the ongoing Coronavirus Disease 2019 (COVID-19) pandemic. The disease was first reported by Tomisaku Kawasaki, a Japanese pediatrician, in a fouryear-old child with a rash and fever at the Red Cross Hospital in Tokyo in January 1961. Now Kawasaki disease is recognized worldwide. The complexity of symptoms was defined as an «acute febrile mucocutaneous lymphnode syndrome". At the moment, it is still unclear whether the coronavirus itself can lead to development of mucocutaneous lymph node syndrome. However, it is believed that COVID-19 virus infection worsens the course of Kawasaki disease, and in some cases, children affected by SARS-V-2 may develop a disease that has a clinical picture similar to Kawasaki disease.
Background:Although guidelines do not recommend antiphospholipid antibodies testing after 60 yo, recent data reported late onset antiphospholipid syndrome (APS).Objectives:To comparatively analyse the clinical, laboratory features and outcomes in 695 cases with primary APS between patients older and younger than 70 yo.Methods:we have performed an international study within the framework of the International Registry of primary APS patients treated with Hydroxychloroquine, HIBISCUS (an ongoing retrospective and prospective register launched in 2016). 28 centres from 17 countries participate. Data about late onset APS were analysed in 695 patients and were obtained from a standardized form registered in the database containing 66 items with respect to demographics, clinical and biological features.Results:Arterial events and especially stroke represented the main initial and recurrent clinical manifestation in 40 primary APS patients older than 70 yo. There were not statistically significant differences with respect to cardiovascular risk factors between the two groups of patients. A significant male predominance, a familial APS history, a higher prevalence of triple positivity, lower complement levels, and anticardiolipin antibodies (aCL) IgA isotype were found in older patients. Low anticoagulation regimens were safe and efficient, with a low relapse rate in older patients.Conclusion:we suggest that the detection of aPL antibodies should be included into the initial screening panel tests in elderly with thrombotic events, especially arterial, in particular those with recurrent stroke and familial APS.Our study further suggests that lower intensity anticoagulation regimens could be a therapeutic option in older APS patients, as no differences in outcomes and relapse rate were found between patients with high and low intensity anticoagulation regimens.References:[1]Grimaud F et al.
