Aim. To study cellular and humoral immunological parameters of the employees of production sites located at the former mining and uranium ore processing territories. Materials and methods. In this work the clinical laboratory and immunological methods of examination were used. Statistical processing of the results was performed by using nonparametric analysis methods in the StatSoft Statistica 6 software package. Results. 101 employees of Chepetskiy mechanical plant were examined at the age of 19-62. 76 (75.2%) of them contacted with industrial factor, 64 - with radiation and 12 - with chemical. 25 (24.8%) employees had no contact with industrial factor. The immunological examination of the employees in contact with industrial factor revealed laboratory signs of imbalance in the immune system with IgE-overproduction. The risk group for secondary immunodeficiency with the leading infectious syndrome was 15.8%. Conclusion. Changes of cellular and humoral parameters on average values were not revealed. Infectious syndrome - recurrent ETN viral infections (13.9%) and herpes virus infection (13.9%) prevailed in the structure of the employees of Chepetskiy mechanical plant. A statistically significant difference in the content (percentage and absolute) of CD16+ lymphocytes was found in the employees of Chepetskiy mechanical plant contacted with industrial factor. These results had no clinical significance, what can be considered as an adaptive response to the chemical factor.

VVD hypotensive type significantly reduces the quality of life, prevents normal growth and differentiation of organs and tissues of the child’s body, promotes the formation of a number of life-threatening pathological processes in adulthood. In order to determine the initial vegetative tonus in 63 children aged 11-14 years suffering from hypotensive type VVD, the averaged values of cardiointervalograms consisting of 100 consecutive cardiocycles were determined. Vegetative reactivity has been studied through the conduct and evaluation of a clinoortostatic test, consisting in the sequential recording of blood pressure and cardiograms first in a horizontal and then in an upright position. As a control group, 27 practically healthy peers were examined, who underwent a similar complex of clinical, laboratory and instrumental studies. Statistical processing of the obtained results was carried out by parametric and nonparametric methods with the help of STATISTICA and Microsoft Excel for Windows packages on the IBM “Pentium 166” computer. As a result of the study, a significant difference in vegetative tone was found in children with hypotensive VVD from normal. In this case, vegetative status is characterized either by the initial high level of functioning of sympathoadrenal regulatory mechanisms with insufficient increase in their adaptive activity or by the predominance of the initial cholinergic vegetative tension and the corresponding hypersympathicotonic reactivity, which is the marker of the greatest threat of transformation in this group of children of the hypersensitive type to the hypertensive and then into hypertensive disease.

Abstract Background High-resolution computed tomography (HRCT) has proved to be an important diagnostic tool throughout the COVID-19 pandemic outbreaks. Increasing number of the infected personnel and shortage of real-time transcriptase polymerase chain reaction (RT-PCR) as well as its lower sensitivity made the CT a backbone in diagnosis, assessment of severity, and follow-up of the cases. Results Two hundred forty patients were evaluated retrospectively for clinical, laboratory, and radiological expression in COVID-19 infection. One hundred eighty-six non-severe cases with home isolation and outpatient treatment and 54 severe cases needed hospitalization and oxygen support. Significant difference between both groups was encountered regarding the age, male gender, > 38° fever, dyspnea, chest pain, hypertension, ≤ 93 oxygen saturation, intensive care unit (ICU) admission, elevated D-dimer, high serum ferritin and troponin levels, and high CT-severity score (CT-SS) of the severe group. CT-SS showed a negative correlation with O2 saturation and patients’ outcome (r − 0.73/p 0.001 and r − 0.56/p 0.001, respectively). Bilateral peripherally distributed ground glass opacities (GGOs) were the commonest imaging feature similar to the literature. Conclusion Older age, male gender, smoking, hypertension, low O2 saturation, increased CT score, high serum ferritin, and high D-dimer level are the most significant risk factors for severe COVID-19 pneumonia. Follow-up of the recovered severe cases is recommended to depict possible post COVID-19 lung fibrosis.

Abstract Background Neonatal HSV infection is associated with substantial morbidity and mortality. Therefore, prompt identification and treatment of infected neonates is paramount. At Nationwide Children’s Hospital (NCH), Columbus, OH all neonates admitted in the first 2 weeks (up to 2010) and 4 weeks (since 2010) of age are evaluated for HSV infection in addition to routine bacterial and other viral infections. The frequency of co-infection with HSV and other potential pathogens is not fully known. Methods Retrospective review of the medical records of infants admitted to NCH with a diagnosis of neonatal HSV infection from 2001 to 2019. Patients less than 6 weeks of age were identified by review of the NCH Virology and Molecular Laboratory results for all positive HSV PCRs obtained from any body site as well as by discharge ICD-9 and ICD-10 codes for HSV infection. Medical records were reviewed for demographic, clinical, laboratory, outcome data, and maternal history of genital HSV lesions at or before delivery. Occurrence of positive bacterial and/or viral co-detection were identified. The data were managed using REDCap electronic data capture tools hosted at NCH. Results There were 93 infants with neonatal HSV infection (mean age, 9.5 days [IQR, 7-15]; 42%, HSV1; 53%, HSV-2). 32 infants had central nervous system infection (CNS) while 31 had Skin-Eye-Mouth (SEM) infection and 30 had Disseminated Disease. Mortality was 15% (n=14). Only 3 mothers had active genital HSV lesions at delivery. Of the 93 infants, 5 (5%) had bacterial (n=2) or viral (n=3) co-infections. All of the infants only had mucosal sites positive for HSV 1 (n=4) or 2 (n=1). Of the 2 infants with bacterial infection, 1 had bacteremia due to viridans streptococci while the other one had necrotizing enterocolitis and a positive blood culture for Clostridium butyricum. The 3 infants with viral co-detection also were full term and all had positive enterovovirus PCR tests (1, blood, throat; 1, blood and ceerebrospinal fluid (CSF); 1, CSF) Conclusion 5% of infants with neonatal HSV infection had bacterial or enteroviral co-infection. These findings have important implications in the management of neonates evaluated for possible sepsis.

Background:Musculoskeletal Ultrasonography (MSUS) is now a widely used tool for monitoring of rheumatoid arthritis (RA). Although there are many proposed sets of composite scores, a fixed set of joints may not be an ideal tool to assess a disease like RA, which affects many joints and tendons in different presentations. In previous study (1) U9 score was proven to be correlated with disease activity parameters.Objectives:To determine whether US assessment using U9 score is useful for monitoring response to treatment for RA or not?Methods:A prospective, multicenter study were conducted in period from July 2019 to December 2019. All recruited RA patients were subjected to: Disease activity assessment by clinical disease activity indices (CDAI and DAS28 ESR). Functional status assessment by (HAQ) and ultrasonographic assessment using U9 score which include 8 joints (bilateral wrists,2ndMCP,3RDMCP and knees) plus most clinically affected joint or tendon (one joint or one tendon). Most clinically affected joints from 48 joints. Any affected tendons could be choosing. All targeted joints were evaluated according to EULAR guidlines and by EULAR/ OMERACT combined score (0-3). Targeted tendons were scored (0-3).All patients received their treatment (biologic and non biologic DMARDs) according to the decision of the treating physicians. No specific therapy is needed. CDAI and DAS28 ESR, HAQ and U9 score were repeated after 3 months to detect the response to change after receiving the therapy.Results:One hundred and forty patients (23.6% were male) with mean age 39.26±11.30 were recruited from 4 tertiary referral university hospitals.There was a significant difference (<0.001) between the first and second visits as regards clinical, laboratory and ultrasonographic parameters. DAS 28 decreased form (5.29±1.21) to (3.95±0.99), ESR decreased from (42.12±15.24) to (26.84±12.32), HAQ2 improved from (0.652±0.350) to (0.510±0.237) and U9 total US score decreased from (13.56±5.18) to (8.02±4.28).There was significant correlation between U9 ultrasonographic score and clinical parameters at both visits (table 1).Table 1.correlation between U9 ultrasonographic score and clinical parameters.U9 at 1stvisitU9 at 2ndvisitDAS-28Pearson Correlation(P value)0.806<0.0010.790<0.001CDAIPearson Correlation(P value)0.787<0.0010.773<0.001HAQPearson Correlation(P value)0.431<0.0010.317<0.001We found that the most suitable cut-off value of U9 score to predict high disease activity was 11.5 (sensitivity 85.7% and specificity 80.6%), cut off value for moderate disease activity was 5.5(sensitivity 83.2% and specificity 88%) and cut off value for low disease activity was 3.5 (sensitivity of 83.3% and specificity 57.1%).

Background: Mangosteen and propolis extracts (MAEC) have been potential therapeutic agents known to exhibit powerful antioxidant and anti-inflammatory properties. The aim of the current study was to evaluate the clinical and immunological efficacy of MAEC as well as safety and patient-reported outcomes (PROMs) on gingivitis and incipient periodontitis. Methods: This study was performed on 104 patients diagnosed with gingivitis or incipient periodontitis. At baseline, the participants were randomly allocated to either the test group, with daily intake of a single capsule containing 194 mg of MAEC for eight weeks, or control group, with placebo. Clinical periodontal evaluation and immunological parameters from saliva and gingival sulcular fluid were assessed at baseline, four, and eight weeks. Individual PROMs were assessed by OHIP-14 questionnaires. Results: There was a significant difference of modified gingival index at four and eight weeks between the test and control groups. In the test group, crevicular interleukin (IL)-6 was reduced, and the salivary matrix metalloproteinase (MMP)-9 was increased after eight weeks. PROMs were improved up to four weeks compared to placebo. Conclusion: Oral administration of MAEC would have a potential to reduce gingival inflammation clinically and immunologically in the patients with gingivitis and incipient periodontitis.

Abstract Objective The interference of the hemoglobin variant (Hb J-Bangkok) was evaluated on 4 different glycated hemoglobin assays and compared with a reference immuno assay. Methods An overall test of coincidence of 2 least-squares linear regression lines was performed to determine whether the presence of Hb J-Bangkok caused a statistically significant difference in HbA1c results compared with a reference immuno assay. Statistical analysis was performed on the difference of the estimated average glucose calculated from HbA1c values and fasting plasma glucose in the Hb J-Bangkok variant group using the different detection systems. Deming regression analysis was used to determinate whether Hb J-Bangkok had a significant interference on HbA1c results using an HbA1c±10% relative bias at 6% and 9% HbA1c as evaluation limits. Results Turbidimetric inhibition immunoassay method, and enzymatic methods were not affected by Hb J-Bangkok. However, Hb J-Bangkok showed statistically significant interference to the two ion-exchange high-performance liquid chromatography methods. Conclusion When performing HbA1c tests, clinical laboratory personnel should identify the Hb variant and select the appropriate methods or use alternative indicators.

Background: Chronic kidney disease (CKD) is well known to increase the risk of cardiovascular disease (CVD). However, there is limited knowledge about the association between CKD in persons living with HIV (PLWH) and CVD. We sought to investigate the prevalence and characteristics of CVD in PLWH with and without CKD at a large single center in South Florida. Methods: A retrospective chart review of 985 of PLWH from a Special Immunology clinic at a large center in South Florida between 2017-2019 was performed. Data on demographics, clinical, laboratory and diagnostic studies were obtained from electronic health records. Results: The prevalence of CKD in PLWH in our cohort was 11%. The group of CKD was older (58 vs. 51 years p<0.05), with significantly more men (66% vs. 53% p=0.012). The CKD cohort had increased rates of hypertension, coronary artery disease (CAD), heart failure, diabetes mellitus, and cerebrovascular disease (<0.05 for all). PLWH with CKD had a significantly higher HbA1C level, systolic and diastolic blood pressure, statin use, and lower LDL-C (p<0.05 for all). Subjects with HIV and CKD had a higher rate of cardiac catheterization (7.2%), with an increased rate of obstructive CAD (6.3%), when compared to PLWH without CKD (1.3% and 0.7%, respectively, p<0.05 for both). The rate of diastolic dysfunction was significantly higher in PLWH with CKD than those without CKD (p=0.004), although, no difference in ejection fraction (p=0.079) was noted. We found a significantly lower average CD4 count in individuals with HIV and CKD compared to those without CKD (483 ± 297 cells/mm 3 vs. 570 ± 342 cells/mm 3 , p=0.006). No significant difference was noted between groups in mean viral load, proportion with undetectable viral load, and use of antiretroviral medications. Prevalence of chronic hepatitis infection (B and/or C) was also higher in the CKD cohort (p<0.05). Conclusion: In this study, we found a comparable rate of CKD compared to age-matched patients from the general population. We found higher rates of traditional CVD risk factors and disease in the CKD cohort, without significant difference in HIV-related factors. This supports the importance of CVD risk factor optimization in this population.

Infertility is the inability of a partner to get pregnant after regular sexual intercourse without contraception for 12 months. Based on the cause, male infertility is caused by genetic, hormonal, infectious, sexual, and unexplained infertility. However, many infertile couples are classified into unexplained infertility without an antisperm antibody (ASA) immunological examination. This study aimed to prove that couples classified as unexplained infertility can be caused by ASA wives. This was an observational study with a cross sectional study design. The sample consisted of 2 groups, in which the first group consisted of 36 fertile couples and the second group consisted of 35 unexplained infertility couples. All samples were carried out indirect MAR test to obtain the ASA value of the wife. If the wife's ASA value was >40%, the ASA results were positive. Conversely, if the ASA value was <40%, the ASA results were negative. From these 2 groups, there was a statistically significant difference (p<0.0001) that the wife's ASA value in the unexplained infertility group was significantly higher than that in the fertile group. This study concluded that the positive ASA results from the indirect MAR test were significantly found in the unexplained infertility sample.

History Of

Subacute thyroiditis is an inflammatory thyroid disorder associated with viral infections. Rare cases of subacute thyroiditis have also been described following vaccination. Recently, a few cases of subacute thyroiditis following SARS-CoV-2 vaccination have also been reported. Here, we present two cases of cytological proven subacute thyroiditis after receiving the first dose of a SARS-CoV-2 vaccination. We describe clinical, laboratory, imaging and cytological findings in two cases of subacute thyroiditis that presented in our department 2 weeks after SARS-CoV-2 vaccination with Spikevax (Moderna Biotech, Spain) and Vaxzevria (AstraZeneca; Sweden). Both cases did not have a previous history of thyroid disorders and presented with anterior and lateral neck pain. Clinical test results as well as cytological findings were consistent with subacute thyroiditis. Subacute thyroiditis may develop following a SARS-CoV-2 vaccination and should be considered as a possible side effect in cases that present with thyroid pain.
