Abstract Background. Approximately 5% of COVID-19 patients suffer near fatal disease. Clinical and radiologic features may predict severe disease albeit with limited specificity and radiation hazard. Laboratory biomarkers are eyed as simple, specific and point of care triage tools to optimize management decisions.This study aimed to study the role of inflammatory markers in prognosticating COVID-19 patients.Methodology. A hospital based retrospective study was conducted on COVID-19 adult inpatients classified into three groups as mild disease-recovered [Group I], severe disease-recovered [Group II] and dead [Group III]. Categorical outcomes were compared using Chi square test. Univariate binary logistic regression analysis was performed to test the association between the explanatory and outcome variables. Unadjusted OR along with 95% CI was calculated. The utility of lab parameters (Ferritin, LDH, D dimer, N/L ratio and PLT/L ratio) in predicting severity of COVID-19 was assessed by Receiver Operative Curve (ROC) analysis. P value < 0.05 was considered statistically significant.Results. The mean age was 49.32 +/- 17.1 years. Among study population, 378 were Group I, 66 Group II, and 56 Group III. Median levels of Ferritin among the 3 groups were 62ng/mL, 388.50 ng/mL and 1199.50 ng/mL. Median value of LDH were 95U/L, 720 and 982.50(p <0.001). D-dimer values of 3 groups were 23.20ng/mL, 104.30 ng/mL and 197.10 ng/mL (p <0.001). CRP done qualitatively was positive in 2 (0.53%), 30 (45.45%) and 53 (94.64%) of patients. The odds of patients suffering severe COVID-19 rose with rising values of ferritin, LDH and D-dimer [unadjusted OR 1.007, 1.004 &1.020]Conclusion. One time measurement of serum ferritin, LDH, D-dimer and CRP is promising to predict outcomes for COVID 19 inpatients. Single qualitative CRP was equally good but more cost effective than quantitative CRP. The most specific combination was NLR, Lymphocyte percentage and D-dimer levels done between 7th – 10th day of symptoms.

Background: COVID-19 patients experience cytokine storm which cause pulmonary and extra-pulmonary complications even with currently available of standard of care. Additional antiviral and immune boosters are the need of hour to treat COVID-19 and to prevent post covid complications.Methods: In this study we enrolled 40 asymptomatic to mild COVID-19 patients to receive azadvir herbal steam inhaler along with standard of care. We evaluated the benefits of azadvir herbal steam inhaler by assessing RT-PCR conversion, clinical outcomes and improvement in immune markers (LDH, CRP, D-DIMER).Results: At the end of the study the immune markers improved significantly in study patients. In mild symptomatic cases IL-6 was 23.2 pg/ml on day 0 and 21.8 pg/ml on day 14. Reduction in IL-6 in mild symptomatic patients was statistically highly significant (p=0.0056). Mean IL-6 in asymptomatic patients was 22.3 pg/ml on day 0 and 21.1 pg/ml on day 14. Reduction in IL-6 in asymptomatic patients was statistically highly significant (p=0.0035).  Mean D-dimer was showing decreasing trend from day 0 to day 14 in mild symptomatic patients. In asymptomatic patients D dimer was 0.8 µg/ml on day 0 and 0.6 µg/ml on day 14. D-dimer decreased significantly from day 0 to day 14 (p value =0.0013). Mean LDH values on day 0 in mild symptomatic patients was 319.4 U/l and 219.3 on day 14. The reduction in LDH values in mild symptomatic patients is statistically significant (p value <0.0122). In asymptomatic patients mean LDH values on day 0 was 237 U/l and 194 U/l on day 14. The reduction in LDH values in asymptomatic group was statistically significant. Mean CRP values in mild symptomatic patients on day 0 was 12.2 mg/l and 3.8 mg/l on day 14. There was significant reduction in CRP values in mild symptomatic group which was statistically significant (p value =0.0546). Mean CRP values in asymptomatic patients on day 0 was 4.9 mg/l and 2.8 mg/l on day 14. There was significant reduction in mean CRP in asymptomatic patients which was statistically significant (p value =0.0446). In the present study all 40 patients (100%) cleared the virus and became negative for RT PCR test within 6 days. None of the patients progressed to severe COVID-19 and none of the patients succumbed to the disease.Conclusions: Azadvir accelerated recovery of COVID-19 patients by RT-PCR conversion, early improvement in clinical symptoms and immune markers in this study. This study results clearly indicates that azadvir has antiviral, immune booster activity and has definitive role in the management of asymptomatic to mild COVID-19 patients along with standard of care (CTRI no. CTRI/2020/06/026181).

Legionella pneumophila is gram-negative bacterium which causes Legionnaires’ disease and Pontiac fever.To determine the frequency of serogroup 1 and other serogroup of Legionellapneumophila in pneumonic patients and the clinical utilityofLegionellapneumoniaurinary antigen test (LPUAT)in terms of sensitivity and specificity andcomparethe results with q Real Time PCR using serum samples. A total of 100 pneumonic patients were enrolled in this studyduring a period between October 2016 to April 2017; all patients under therapy with antibiotics.Serum and urine specimens were obtained from all patients; urine samples were processed for urinary antigen test. Serum samples were collected and submitted to DNA extraction for detection of L. pneumophila mip gene by q RT PCRassay. The percentage of L. pneumophila in two hospitals In Baghdad was 30%. Of these 26% was serogroup 1 detected by UAT. In the other hand, 23 % of samples were positive by q RT- PCR based mip gene,of these 19 % were serogroup 1 and 4% were other serogroups. The sensitivity of UAT is high (P value< 0.001), which means statistically highlysignificance than q RT PCR. Legionellapneumophila urinary antigen test is a rapid tool for early diagnosis of Legionella infection which highlights the need of using this test in hospitals and health institutions and there is a high prevalence of L.pneumophila in Iraqthat refer to the necessity of considering this microorganism point of view in future studies for detection and treatment in pneumonic patients.

Background:: The understanding of pathogenesis is necessary for the development of effective treatment for COVID-19. Various studies have postulated that there is a complex interplay of mediators of coagulation and inflammation responsible for the pathogenesis of COVID-19. We did this study on coagulation parameters and inflammatory markers and their effect on outcome in patients with COVID-19. Methods: This was a single centre observational cross-sectional study. Procoagulants [Prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, lupus anticoagulant (LA), fibrinogen, factor-VIII (F-VIII)]; anticoagulants [protein-C (PC), protein-S (PS), antithrombin] and inflammatory markers [interleukin-6 (IL-6) and highly sensitive – C-reactive protein (hs-CRP)] were measured at the time of hospitalization and correlated with the severity of the disease. Results: A total of 230 patients were enrolled, of which 61.3%, 20.0%, and 18.7% had asymptomatic/ mild, moderate, or severe disease, respectively. COVID-19 disease severity was associated with rising trends with coagulation parameters (PT, APTT, D-Dimer; p value 0.01, <0.0001, <0.0001, respectively). Falling trends of anticoagulant (PC, Antithrombin; p value <0.0001, 0.003 respectively) and rising trends of procoagulant (fibrinogen, F-VIII; p value 0.004, <0.0001 respectively) were observed with increasing COVID-19 disease severity. Multivariate logistic regression analysis found that advanced age, D-Dimer, and hs-CRP (p value 0.035, 0.018, <0.0001 respectively) were independent predictors of mortality in COVID-19. Procoagulant parameters (D-dimer, APTT, Factor VIII) were positively correlated with anticoagulant parameters (PC and PS) and inflammatory parameters (hs-CRP). Conclusions: This study revealed increased levels of coagulation and inflammatory parameters, which correlated with the severity of COVID-19. Age, D-dimer, IL-6, hs-CRP, APTT, fibrinogen, and Factor VIII were significantly higher in patients with moderate and severe disease as compared to asymptomatic/mild disease. Advanced age, D dimer, and hs-CRP were significantly associated with poor outcomes.

Background: The novel coronavirus ( SARS CoV 19) is responsible for the pandemic infection after starting in 2019 in Wuhan city /China, several small studies were done since then to determine the effects of smoking on the severity, outcome & mortality of patients with COVID-19 but the results were inconclusive, this study aims to assess the impact of active smoking on severity and outcome in patients with COVID-19 infection in Mosul city/Iraq. Methods: A prospective cohort study was conducted on 160 patients ( 80 patients were active smokers & 80 non-smoker patients) who have been diagnosed with COVID-19 infection by using real-time PCR, the study was done at Ibn-Sina teaching hospital in Mosul city/Iraq from May 2020 until December 2020. A detailed history was taken from the patients, full clinical examination & blood tests were done. The following parameters were recorded & compared between the 2 groups: severity of symptoms, inflammatory markers, D dimer, liver function test (LFT), oxygen use, hospitalization & outcome. Results: the symptoms of COVID-19 were more severe in the non smokers group (34.4%) compared to the smokers (25%) & it was statistically significant (p-value = 0.016), the inflammatory markers were also higher in the non-smokers (31.9%) compared to the smokers (20.0%) ( p-value = 0.011) , D dimer & LFT were also higher in the non-smoker group ( p-value = 0.01 & 0.008 respectively). There was no statistical difference regarding oxygen use, hospitalization, ICU admission, mortality, or post-recovery complications. Conclusion: severe symptomatic COVID-19 infection was more common in the non-smoker group, the inflammatory markers, D-dimer & LFT were higher in the non-smokers compared to the smokers. No statistical difference was found regarding O2 use, hospitalization, ICU admission, mortality & residual complications.

Introduction and Aim: Various hematological and biochemical parameters are assessed as biomarkers of COVID-19, caused by the SARS-CoV-2. In this study, efforts were made to identify the correlation of cytokines (IL-6, TNF-?, IL-1?, and IL-1?) with the liver function enzyme markers, LDH, CRP, Ferritin, and D-dimer. We also assessed the correlation of cytokines with severity of COVID-19.   Materials and Methods: We analyzed 53 serum samples of RT-PCR-positive patients admitted to the hospital. Cytokines (IL-6, TNF-?, IL-1?, and IL-1?) were analyzed with sandwich ELISA.  The levels of cytokines were compared between mild, moderate, and severe cases of COVID-19, and the correlation among cytokines, liver function marker enzymes, LDH, CRP, D-dimer, and ferritin were analyzed.   Results: Along with CRP, LDH and ferritin, IL-6 showed significant difference between mild, moderate, and severe COVID groups. significant correlation between IL-6 & LDH (p -.002), IL-6 & D-Dimer (p- .010), IL-6 & IL-1? (p- .027), IL-1? & D-Dimer (p- .010), IL-1? & LDH (p-.027), and IL-1? & TNF-? & (p-.000).   Conclusion: Cytokines especially IL-6 correlated with disease severity. Assaying the profile of cytokines could be of immense value in diagnosis, prognosis, and management of COVID-19.

Background: Oxandrolone is a synthetic testosterone analogue that is widely used among bodybuilders and athletes. However, oxandrolone causes male infertility. Recently, it was found that metformin reduces the risk of infertility associated with diabetes mellitus. Aim: This study aimed to investigate the protective effects of metformin against oxandrolone-induced infertility in male rats. Methods: Rats continuously received one of four treatments (n=7) over 14 days: control DMSO administration, oxandrolone administration, metformin administration, or co-administration of oxandrolone and metformin. Doses were equivalent to those used for human treatment. Subsequently, testicular and blood samples were collected for morphological, biochemical, and histological examination. In addition, gene expression of the testosterone synthesizing enzyme CYP11A1 was analyzed in the testes using RT-PCR. Results: Oxandrolone administration induced male infertility by significantly reducing relative weights of testes by 48%, sperm count by 82%, and serum testosterone levels by 96% (ANOVA, P value < 0.05). In addition, histological examination determined that oxandrolone caused spermatogenic arrest which was associated with 2-fold downregulation of testicular CYP11A1 gene expression. However, co-administration of metformin with oxandrolone significantly ameliorated toxicological alterations induced by oxandrolone exposure (ANOVA, P value < 0.05). Conclusion: Metformin administration protected against oxandrolone-induced infertility in male rats. Further clinical studies are needed to confirm the protective effect of metformin against oxandrolone-induced infertility among athletes.

Background: We report an outbreak of SARS coronavirus-2 (SARS-CoV-2) infection among healthcare workers (HCW) in an NHS elective healthcare facility. Methodology: A narrative chronological account of events after declaring an outbreak of SARS-CoV-2 among HCWs. As part of the investigations, HCWs were offered testing during the outbreak. These were: (1) screening by real-time reverse transcriptase polymerase chain reaction (RT- PCR) to detect a current infection; and (2) serum samples to determine seroprevalence. Results: Over 180 HCWs were tested by real-time RT-PCR for SARS-CoV-2 infection. The rate of infection was 15.2% (23.7% for clinical or directly patient-facing HCWs vs. 4.8% in non-clinical non-patient-facing HCWs). Of the infected HCWs, 57% were asymptomatic. Seroprevalence (SARS-CoV-2 IgG) among HCWs was 13%. It was challenging to establish an exact source for the outbreak. The importance of education, training, social distancing and infection prevention practices were emphasised. Additionally, avoidance of unnecessary transfer of patients and minimising cross-site working for staff and early escalation were highlighted. Establishing mass and regular screening for HCWs are also crucial to enabling the best care for patients while maintaining the wellbeing of staff. Conclusion: To our knowledge, this is the first UK outbreak report among HCWs and we hope to have highlighted some key issues and learnings that can be considered by other NHS staff and HCWs globally when dealing with such a task in future.

A serological survey for bovine viral diarrhoea virus (BVDV) antibodies on a collection of 1295 serum samples obtained from 6-12 months old cattle originating from 45 farms in Slovakia was carried out. On 13 farms more than 90% of the examined animals were seropositive, on 14 farms 71-90% seroprevalence was observed, on 13 farms only 50-70% animals were found to be positive for BVDV antibodies, while the remaining 5 farms showed fewer than 50% seropositive animals. The average incidence of BVDV antibodies (around 70%) was similar as determined 30 years ago. Of 84 serum samples from seronegative animals originating from 14 farms in which 70-98% seropositivity was observed, six were positive in Ag-BVDV ELISA indicating persistently infected (PI) cattle. On a farm to which animals were imported from abroad, a BVD outbreak was observed. Of 110 animals tested, four were positive in Ag-ELISA indicating the presence of PI cattle on this farm. Genetic typing of two isolates from imported animals performed by RT-PCR (324/326 primers from 5´-UTR), sequencing of PCR products and computer-assisted phylogenetic analysis revealed that they belong to BVDV-1h group.

This report describes the first prevalence of antibodies and experimental inoculation of suspected samples of porcine reproductive and respiratory syndrome virus (PRRSV) from ELISA positive pigs from swine herds in Brazil. Based on the hypothesis that this agent is present in swine herds worldwide, the objective of this work was to establish a diagnostic methodology and to investigate the occurrence of PRRSV in Brazilian swine herds. Fifty-four swine herds, the total number which imported genetic material (live pigs or swine semen) from countries where PRRS was endemic from 1990 to December 2000, from eight Brazilian States all included in this study. The sampling used was such as to detect a prevalence of infection of 5%, with a confidence level of 95%. A total of 3785 serum samples were tested for PRRSV antibodies by ELISA. Following the ELISA test, which was performed with two different commercial kits, all serum positive pigs were retested, examined and additional materials were collected. Viral isolation in permissive tissue culture cells and swine bioassays were performed. Additionally, reverse transcriptase polymerase chain reaction (RT-PCR) and nested RT-PCR were also performed. We could not demonstrate the presence of PRRSV or RNA of PRRSV by viral isolation or RT-PCR (or nested RT-PCR), respectively in all of the analyzed samples. Furthermore, the pigs inoculated with PRRSV suspicion samples did not seroconvert nor produce characteristic PRRS lesions in the swine bioassay. Thus, our results indicate no evidence of PRRSV in the samples analyzed from swine herds in this study.
