Background:Anti-B-cell therapy is seen as a promising therapeutic option for systemic sclerosis (SSc). The study of antinuclear antibody levels during treatment with rituximab (RTX) in patients (pts) with SSc could have theoretical and practical interest.Objectives:To assess the changes in ANA, anti-topoisomerase-1 (Scl-70) levels and B-lymphocytes (B-lymph) count during RTX therapy during prospective observation.Methods:This prospective study included 88 pts with SSc, 83% of them had interstitial lung disease and 75% had positive Scl-70 autoantibody. The mean age was 47 yrs (17-71), female-73 pts (83%), the diffuse cutaneous subset of the disease had 50 pts (57%). The mean disease duration was 5,9±4,8 yrs. The mean follow-up period was 27 months (12-42). The cumulative mean dose of RTX was 2,9±1,1grams. All patients received prednisolone at a dose of 11,7±4,4 mg, immunosuppressants received 42% of them. Patients were divided into groups depending on the duration of the disease: group 1 (n=33) - up to 3 yrs, group 2 (n=25) - from 3 to 6 yrs, group 3 (n=30) - more than 6 years (6-18yrs). The results are presented in the form of mean values, median, upper and lower quartiles.Results:Parallel to clinical improvement in most patients (96%) we found positive changes in many parameters at the end of the study compared to the baseline. The Rodnan skin score decreased from 11,21±9,33 to 6,19±4,74 (p<0,001). The disease activity index (EScSG-AI) decreased from 2,9±1,74 to 1,36±1,15 (p<0,001). Forced vital capacity, % predicted, increased from 76,35±19,65 to 84,37±21,04 (p<0,001). Diffusing capacity for carbon monoxide, % predicted, increased from 45,56±17,72 to 47,62±16,96 (p<0,019). The dose of prednisolone decreased from 11,7±4,4 to 9,2±3,2 mg (p<0,001). The absolute number of B-lymph decreased from 0,224±0,19 to 0,0175±0,058 (p<0,001). The pts of the group 1 showed the highest values of B-lymph at baseline and level of B-lymph decreased from 0,326±0,22 to 0,008±0,01 (Δ 0,318) at the end of the study. In group 2 depletion was less pronounced (from 0,197±0,14 to 0,026±0,07 (Δ 0,171) and the lowest depletion was observed in group 3 (from 0,151±0,16 to 0,019±0,07 (Δ 0,131), p<0,001 for all groups. An initially positive ANA was found in 92% of pts (range 1/320-1/1280). During observation, the number of pts with high (1/640-1/1280) ANA titers decreased from 70 to 41 (p<0,001), and the average level of ANA decreased by 30-40% in all groups. At baseline 63 pts (75%), had positive Scl-70 with equal levels in all groups. At the end of the study level of Scl-70 decreased from 125,02±89,12 to 108,6±86,89 units/ml (p<0,007). A negative correlation was found between the duration of the disease and ANA (r = -0,54; p<0,003) and Scl-70 (r = -0,44; p<0,017).Conclusion:In our study a clinical improvement was shown in most pts at the long-term complex therapy, including RTM. We found a significant decrease in the absolute number of B-lymph, as well as decrease of ANA and Scl-70 levels. Initially pts with a short duration of the disease had a higher level of B-lymph and in these pts depletion was more pronounced, compared to those with a longer duration of the disease. However, the level of Scl-70 and ANA decreased both to those who started RTX therapy at an early stage of the disease (<3yrs) and to those who had a long disease duration.Disclosure of Interests:None declared

Granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood progenitor cells (PBPC) have successfully been used as stem cells for both autologous and allogeneic transplants. However, little is known concerning the absolute number and phenotype of primitive progenitors, such as long-term culture-initiating cells (LTC-IC) in mobilized PBPC. The aim of our study was to evaluate the capacity of G- CSF to mobilize LTC-IC in the PB of normal individuals and to evaluate the phenotypic and functional characteristics of G-CSF mobilized LTC- IC. G-CSF was administered to 29 healthy volunteers at 7.5 micrograms or 10 micrograms/kg/d subcutaneously (SC) for 5 consecutive days and PBPC were harvested on day 6. Mobilization with G-CSF increased the absolute number of week 5 LTC-IC in PB 60-fold, while the number of CD34+ cells and committed colony forming cells (CFC) was increased sevenfold to 12-fold. The frequency of CFC and week 5 LTC-IC in CD34+ cells selected by fluorescence-activated cell sorter (FACS) from mobilized PBPC was 2 +/- 0.3-fold and 9 +/- 2.2-fold higher respectively than in CD34+ cells selected from unmobilized PBMNC. CFC were enriched in the CD34+ CD38+ and CD34+ HLA-DR+ populations. The absolute number of LTC-IC present in CD34+ CD38- and CD34+ HLA-DR- cells selected by FACS from either mobilized PBPC, unmobilized PBMNC or steady state bone marrow (BM) was similar (0.5% to 2%). In contrast to unmobilized PBMNC or steady state BM CD34+ CD38+ and CD34+ HLA-DR+ cells, which contain less than 0.1% LTC-IC, CD34+ CD38+ and CD34+ HLA- DR+ cells sorted from mobilized PBPC contained 0.5% to 5% of cells capable of sustaining hematopoiesis in long-term cultures for 5 weeks. However, 90% to 95% of LTC-IC present in mobilized CD34+ CD38+ and CD34+ HLA-DR+ cells were not able to sustain hematopoiesis for 8 weeks, while 30% of CD34+ CD38- and CD34+ HLA-DR- LTC-IC present in mobilized PBPC could sustain hematopoiesis for at least 8 weeks. This suggests that the majority of CD34+ CD38+ and CD34+ HLA-DR+ week 5 LTC-IC represent progenitors at an intermediate state of differentiation. We conclude that G-CSF effectively mobilizes LTC-IC in the blood of normal individuals. Although a fraction of these cells has functional characteristics similar to those of steady state PBMNC or BM LTC-IC, more than 85% of mobilized PBPC LTC-IC are CD34+ CD38+ and CD34+ HLA- DR+, capable of sustaining hematopoiesis for 5 weeks, but not for 8 weeks. The functional and phenotypic characterization of primitive and more mature populations of LTC-IC in mobilized PBPC should prove extremely useful in future studies examining the role of these progenitors in engraftment following transplantation.

The study and monitoring of international indicators of the health status of premature infants is the current vector of scientific research in neonatology.Objective. To assess the effectiveness of the nursing technologies of premature babies in the Republic of Belarus based on the analysis of long-term indicators of morbidity, mortality and survival of the infants with extremely low body weight.Material and methods. Statistical reports data were used for a retrospective analysis of epidemiological indicators for the period of 2002–2018.Results. The proportion of premature infants in the Republic of Belarus was stabilized at 4,2–4,5% increase in the absolute numbers, including those born weighing less than 1500 g. The ratio of the absolute number of alive and stillborn infants with extremely low body weight is many times higher than the initial values (p<0,05). The survival rate of infants with a body weight of 500–999g up to 1 year increased 2 times to the maximum level in 2018 (81,5%). There was an increase in the overall incidence of premature children in 2002–2010 (p<0,05) and a decrease by 2016 (p=0,001), including those born with a body weight of 500–999 g. Respiratory distress syndrome, intrauterine hypoxia and asphyxia during childbirth, an increase in the frequency of infections specific to the perinatal period (p <0,05) were registered more often. Among the children born with a body weight of 500–999 g, the incidence of congenital pneumonia for the period 2002–2009 increased to a maximum level of 263,4 ‰ (p <0,05) with a twofold decrease by 2018. The republican mortality rate of premature babies was stabilized at the level of 0,95 ‰ in the last 9 years, while the indicator was decreased 5 times among children weighing 500–999 g.Conclusion. The assessment of the long-term dynamics of the main indicators of the health status of premature infants in the Republic of Belarus testified to the effectiveness of a complex of organizational and medical measures for their nursing.

In spite of the fact that food production in developing countries doubled over the last 25 years undernutrition is still widely spread. At the beginning of the eighties, according to FAO, 335 to 494 million people in developing countries suffered from serious undernutrition the difference being due to different concepts to determine undernutrition on which scientist were unable to find a consensus.) Unfortunately there is no recent comprehensive analysis of the food situation comparable to those of previous World Food Surveys but it can be taken for sure that the absolute number of undernourished has increased. According to unofficial FAO sources a figure of 870 million was estimated for 1990 (22 percent of the total population in developing countries) using the same concept that led to the figure of 494 million in 1979-81 (23 percent of the total population in developing countries) which means that most probably the number of undernourished increased at a rate slightly less than population growth.

Ketamine has been shown to be efficacious for the treatment of depression, specifically among individuals who do not respond to first-line treatments. There is still, however, a lack of clarity surrounding the clinical features and response periods across samples that respond to ketamine. This paper systematically reviews published randomized controlled trials that investigate ketamine as an antidepressant intervention in both unipolar and bipolar depression to determine the specific clinical features of the samples across different efficacy periods. Moreover, similarities and differences in clinical characteristics associated with acute versus longer-term drug response are discussed. Similarities across all samples suggest that the population that responds to ketamine’s antidepressant effect has experienced chronic, long-term depression, approaching ketamine treatment as a “last resort”. Moreover, differences between these groups suggest future research to investigate the potential of stronger efficacy towards depression in the context of bipolar disorder compared to major depression, and in participants who undergo antidepressant washout before ketamine administration. From these findings, suggestions for the future direction of ketamine research for depression are formed.
