One of the main genetic factors of the development of atopic dermatitis (AD) in children are single nucleotide polymorphisms (SNP) of the filagrin gene (FLG), particularly rs_7927894 FLG. One of the mostly studied and promising AD marker chemokines (CK) is the thymusE and activation regulated chemokine (TARC/CCL17). Purpose – to detect the associations and role of different variants of SNP rs_7927894 FLG gene and TARC/CCL17 in children suffering different AD clinical proE files (CP) – isolated or combined with comorbid atopic disorders (AtD). Materials and methods. The main group comprised 39 patients aged 3 to 18 years, suffering the isolated AD or combined with comorbid AtD. The control group comprised 47 patients aged 3 to 18 years, suffering the pathology of gastrointestinal tract without clinical signs of atopy. All the patients of the main and control groups had undergone detection of the genotype variants of SNP rs_7927894 FLG gene by real-time polymerase chain reaction and detection of TARC/CCL17 serum concentrations in venous blood. The cutEoff value of statistical significance was set as p<0.05. Results. The incidence and association of genotype variants C/C, C/T and T/T SNP rs_7927894 FLG gene in patients of cohorts of the studied groups were detected as follows: C/T rs_7927894 FLG was significantly the most common in the general main group (56.4%, p<0.05), within the cohort of CP AD isolated (61.1%, p<0.05) and CP of AD combined with comorbid AtD (52.4%, p<0.05). There were detected the associations of studied SNP with AD: C/T rs_7927894 FLG is significantly directly associated with AD (r=0.291, p<0.05), C/C rs_7927894 FLG has a reverse association with a trend to significance (r=-0.194, p=0.07). Mean serum concentrations of TARC/CCL17 did not differ significantly among patients cohorts of the main and control groups, respectively: general main group — 615.8 pg/ml, main with a CP AD isolated — 651.3 pg/ml, main with a CP of AD combined with comorbid AtD — 585.4 pg/ml, control — 608.4 pg/ml (p>0.05). Associations of serum TARC/CCL17 concentrations were determined as follows: elevation trending to significance within increasing AD severity degree (r=0.290, p=0.07) and significant elevation within the AD exhacerbation period (r=0.426, p<0.05). No significant association of TARC/CCL17 as to AD patients compared to the control group was detected in our study (r=-0.027, p>0.05). Conclusions. The genotype heterozygote variant C/T rs_7927894 FLG is significantly the most common and associated with all AD CP in children — isolated and combined with comorbid AtD. Variant C/C rs_7927894 of FLG gene is significantly reversely associated with AD in children. Serum concentrations of TARC/CCL17 did not reveal any significant differences between the AD patients and nonEatopic ones. However, they significantly elevate within AD exacerbation phase and trending to significance within AD severity degree increase in children. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: atopic dermatitis, children, associations, polymorphism, filaggrin, thymus- and activation regulated chemokine.

Background Antioxidants show nephroprotective effect against vancomycin associated nephrotoxicity (VAN) in animals. This study aimed to assess the ascorbic acid nephro-protective role against VAN clinically. Methods Forty-one critically ill patients were randomly assigned to one of two groups: intervention group (vancomycin IV plus ascorbic acid, n=21) or control group (vancomycin IV only, n=20). Primary outcomes were the incidence of VAN and the absolute change in creatinine parameters, while mortality rate was the secondary outcome. Nephrotoxicity was defined as an increase in serum creatinine (S.cr) by at least 0.5 mg/dL or 50% of baseline for at least two successive measurements. This study is registered at Clinicaltrials.gov (NCT03921099), April 2019. Results Mean absolute S.cr increase was significant when compared between both groups, P-value = 0.036, where S.cr increased by 0.05(0.12) and 0.34(0.55) mg/dL in the intervention and control groups, respectively. Mean absolute Cr.cl decline was significant when compared between both groups, P-value = 0.04, where Cr.cl was decreased by 5.9(17.8) and 22.3(30.4) ml/min in the intervention and control groups, respectively. Incidence of VAN was 1/21(4.7%) versus 5/20(25%) in the intervention and control groups, respectively (RR: 0.19; CI: 0.024–1.49; P-value = 0.093). Mortality was higher in the control group; however, it was not statistically significant, P-value = 0.141. Conclusion Co-administration of ascorbic acid with vancomycin preserved renal function and reduced the absolute risk of VAN by 20.3%, however, the reduction in VAN incidence didn’t reach statistical significance level. Further large multicenter prospective trials are recommended.

ABSTRACT In this study, 20 women with staphylococcal mastitis were randomly divided in two groups. Those in the probiotic group daily ingested 10 log10 CFU of Lactobacillus salivarius CECT5713 and the same quantity of Lactobacillus gasseri CECT5714 for 4 weeks, while those in the control one only ingested the excipient. Both lactobacillus strains were originally isolated from breast milk. On day 0, the mean staphylococcal counts in the probiotic and control groups were similar (4.74 and 4.81 log10 CFU/ml, respectively), but lactobacilli could not be detected. On day 30, the mean staphylococcal count in the probiotic group (2.96 log10 CFU/ml) was lower than that of the control group (4.79 log10 CFU/ml). L. salivarius CECT5713 and L. gasseri CECT5714 were isolated from the milk samples of 6 of the 10 women of the probiotic group. At day 14, no clinical signs of mastitis were observed in the women assigned to the probiotic group, but mastitis persisted throughout the study period in the control group women. In conclusion, L. salivarius CECT5713 and L. gasseri CECT5714 appear to be an efficient alternative for the treatment of lactational infectious mastitis during lactation.

ABSTRACT A cattle trial using artificially inoculated calves was conducted to determine the effect of the addition of colicinogenic Escherichia coli strains capable of producing colicin E7 (a 61-kDa DNase) to feed on the fecal shedding of serotype O157:H7. The experiment was divided into three periods. In period 1, which lasted 24 days, six calves were used as controls, and eight calves received 107 CFU of E. coli (a mixture of eight colicinogenic E. coli strains) per g of feed. Both groups were orally inoculated with nalidixic acid-resistant E. coli O157:H7 strains 7 days after the treatment started. In periods 2 and 3, the treatment and control groups were switched, and the colicinogenic E. coli dose was increased 10-fold. During period 3, which lasted as long as period 1, both groups were reinoculated with E. coli O157:H7. The numbers of E. coli O157:H7 were consistently greater in the control groups during the three periods, but comparisons within each time period determined a statistically significant (P < 0.05) difference only at day 21 of period 1. However, when the daily average counts were compared between the period 1 control group and the period 3 treatment group that included the same six animals, an overall reduction of 1.1 log10 CFU/g was observed, with a maximum decrease of 1.8 log10 CFU/g at day 21 (overall statistical significance, P = 0.001). Serotype O157:H7 was detected in 44% of the treatment group's intestinal tissue samples and in 64% of those from the control group (P < 0.04). These results indicated that the daily addition of 108 CFU of colicin E7-producing E. coli per gram of feed could reduce the fecal shedding of serotype O157:H7.

To assess endothelial function in the newborns born to mothers with preeclampsia and without preeclampsia the scientists assessed the content of nitricoxide and hydrogen sulfide in the umbilical and venous blood of these children. The main group consisted of 80 women with moderate preeclampsia and their80 newborns; the control group included 50 children born to women without preeclampsia. The authors studied the content of nitric oxide by determining the totalnitrates and nitrites (NOx), hydrogen sulfide in mixed cord blood collected within 30 minutes after delivery, and venous blood taken from newborns on the 1-3rd day of life. Umbilical cord blood demonstrated no significant differences in the content of NO xand hydrogen sulfide in newborns of the main and control groups. However, in general, the study of umbilical cord blood revealed a relationship between the concentration of hydrogen sulfide and the possibility of developing intraventricular hemorrhagein a newborn of the main and control groups. In the venous blood there was a significant increase in the content of NOx and hydrogen sulfide in newborns born to mothers with preeclampsia. It may cause vasodilation asa compensatory reaction of the body during the period of postnatal adaptation of the child’s body, aimed at life support.

Introduction. In patients with chronic loco-motor system diseases the pain often persists after arthroplasty and does not respond to symptomatic therapy.Purpose of study: to evaluate the efficacy of perioperative use of Meloxicam in patients after hip arthroplasty. Patients and methods. The follow-up covered 120 patients (mean age 64.4±5.23 years) after hip arthroplasty. In the main group (n=60) Meloxicam was given 7 days prior to and 3 weeks after surgery; after intervention narcotic analgesic was used on the request. In control group (n=60) the patients were only on narcotic analgesic on request after operation. Treatment results were assessed by 100-millimeter visual analog scale (VAS) and D’Aubigné-Postel Score.Results. Seven days before the surgery the pain severity in the main and control groups was comparable: 85±2.3 and 84±2.1, respectively. In 2 days after operation the pain relief was more pronounced in the main group — 69±2.1 mm versus 82±3.4 mm in the control group (p0.05). In 3 months those indices made up 10±2.1 and 35±12.6 mm (p0.001), respectively. In the main group the result was assessed as the excellent and good in 22 patients, in the rest of patients as satisfactory by d’Aubigné-Postel Score. In the control group the good result was recorded in 9, satisfactory — in 47 and poor — in 4 cases.Conclusion. Meloxicam may be considered as an effective perioperative analgesic in large joints arthroplasty.

Abstract Background Atopic dermatitis (AD) incidence has increased over the past decades, especially among young adults. However, their bone health has not been clearly elucidated with discordant results. Objective We aimed to investigate the bone mineral density (BMD) measured by double energy X-ray absorptiometry and Z-score at the lumbar spine, femur neck, and total femur to evaluate the risk of osteoporosis in men aged <50 years and premenopausal women with AD.Methods The Korea National Health and Nutrition Examination Survey 2007-2009 data were used in this case-control cohort study. We included young AD patients (aged 19≤ and <50 years) diagnosed by a doctor and compared these patients with 1:5 propensity score weighting controls by age, sex, body mass index (BMI), vitamin D level, and alcohol/smoking status. Results We analyzed 311 (weighted n=817,014) AD patients and 1,555 (weighted n=4,155,855) controls. BMD at the lumbar spine was significantly lower in the male AD group than in the male control group (mean ± SE, 0.989 ± 0.002 vs. 0.954 ± 0.016, P = 0.03) while BMDs at the femur neck and total femur were comparable. For women, BMDs at the three sites were not significantly different between the AD and control groups. Low bone mass (defined by a Z-score of ≤2.0) was not significantly different between the AD and control groups in both sexes. Conclusions Bone health, especially BMD and Z-score, in young AD patients were comparable with those without AD. AD was not a risk factor for low BMD.

Hypothesis/aims of study. It is assumed that intestinal dysbiosis, as well as bacterial vaginosis, may be one of the risk factors, and in some cases, the direct cause of pregnancy complications. This study was aimed to assess the intestinal and vaginal microbiocenosis composition in women with threatened miscarriage and normal pregnancy. Study design, materials and methods. The study involved 68 women aged 18 to 35 years (mean age 27.6 0.7 years) in pregnancy from 6 to 18 weeks. The main group consisted of 38 women with threatened miscarriage. The control group included women (n = 30) with normal pregnancy. Patients of the main and control groups were examined in accordance with the requirements of the Ministry of Health order No. 572n. In addition, a qualitative and quantitative microbiological analysis of vaginal discharge and feces was performed using the real-time polymerase chain reaction method. Results. Vaginal dysbiosis was detected in 60.5% of pregnant women of the main group and only 13.3% of women of the control group. In the main group, grade II dysbiosis was found in 23.7% of cases, and grade I dysbiosis in 36.8% of cases, while in the control group, these grades were found only in 3.3% and 10% of cases, respectively. Intestinal dysbiosis was diagnosed in 100% of the examined pregnant women. In patients of the main group, intestinal dysbiosis was detected as follows: grade I in 29% of cases, grade II in 52.6% of cases, and grade III in 18.4% of cases. In patients of the control group, the disorders corresponded mainly to grade I (83.4%) and, to a lesser extent, grade II (16.6%) dysbiosis, there being no cases of severe dysbiosis revealed. Conclusion. Women with threatened miscarriage had the most pronounced dysbiotic changes in vaginal and intestinal microflora compared to the control group. Vaginal dysbiosis was combined with intestinal dysbiosis in 100% of cases in patients of the main and control groups, and the degree of dysbiotic changes in the vaginal microflora was directly proportional to the degree of intestinal dysbiosis.

BACKGROUND: Alopecia areata is a non-scarring hair loss, which typically starts quickly. Atopy is one of the possible predisposing risk factors for this condition.AIM: This study aimed to evaluate the prevalence of thyroid disease, atopic dermatitis and allergic diseases in children with alopecia areata and compare the results with healthy individuals.METHODS: This case-control study was conducted on 50 patients with alopecia areata, diagnosed by a dermatologist, and 150 healthy individuals as the control group. Participants filled the questionnaires, and necessary tests were performed.RESULTS: In this study, the mean age of the participants was 2.55 ± 14.26 and 3.19 ± 11.92 in the case and control groups, respectively. Prevalence of asthma was 22% in the case group and 12.5% in control group (P = 0.109). Also, allergic rhinitis and eczema were observed in 20% and 22% of the subjects of the case group, whereas they were reported to be 8% and 10% in the control group (PV = 0.03 and 0.175, respectively). Moreover, 28% and 8% of the participants in the case and control groups had a family history of atopy and allergic disorders, respectively (P = 0.046). A significant difference was observed between the two groups regarding gender, type of delivery and contact with animals.CONCLUSIONS: According to the results of this study, a significant association was observed between the prevalence of alopecia areata and atopic conditions, such as allergic rhinitis and history of atopic dermatitis.

Objective.To evaluate the prevalence rates of peripheral joint, enthesis, tendon, and bursa abnormalities by power Doppler (PD) ultrasonic examination in patients with psoriatic arthritis (PsA), psoriatic patients without clinical signs of arthritis (non-PsA psoriasis group), and healthy individuals, to detect subclinical PsA.Methods.A total of 253 healthy volunteers, 242 non-PsA psoriatic patients, and 86 patients with PsA were assessed by 2-dimensional and power Doppler (PD) ultrasound. Peripheral joint, enthesis, tendon, and bursa abnormalities were observed, characterizing abnormal PD. The affected patients and sites with abnormalities in various ages were compared among groups; PD signal grades for the abnormalities were also compared.Results.In the PsA group, significantly higher percentages of sites showing joint effusion/synovitis, enthesitis, and tenosynovitis in all age groups, and markedly higher rates of sites with bursitis were found in young and middle age groups, compared with the non-PsA and control groups (all p < 0.01). Meanwhile, the non-PsA group showed significantly higher rates of joint effusion/synovitis and enthesitis sites, and elevated PD signal grades of synovitis, enthesitis, and tenosynovitis in comparison with the control group, both in young and middle age groups (all p < 0.01).Conclusion.Patients with PsA have high percentages and PD signal grades of peripheral joint, tendon, enthesis, and bursa involvement. Young and middle-aged non-PsA patients have high synovitis and enthesitis percentages, and elevated PD signal grades of synovitis, enthesitis, and tenosynovitis.
