The reliable detection of T cell response to COVID-19 or COVID-19 vaccination is important for individual patient care and for monitoring the immune response e.g. in COVID-19 vaccine trials in a standardized fashion.
OBJECTIVES AND STUDY DESIGN
We used blood samples from health care workers (HCW) with or without history of COVID-19 to define test accuracy of a novel interferon-textgreekg release assay (IGRA). For a real-life performance evaluation, we analysed interferon-textgreekg response to complete COVID-19 vaccination in HCW receiving homologous or heterologous vaccination regimens and in patients receiving immunosuppressive or immune modulating therapies.
RESULTS
The assay had a specificity of 100%. Sensitivity of the IGRA to detect past infection was 72.2% after infection more than 5 months ago and 93.8% after COVID-19 up to 5 months ago. Quantitative results showed significant differences between first and second vaccine dose, but no difference between homologous and heterologous vaccination regimen. Immunocompromised patients often had no immune response or isolated T cell or antibody response to complete vaccination.
CONCLUSIONS
The novel IGRA proved to be a highly specific tool to detect SARS-CoV-2 specific T cell response to COVID-19 as well as COVID-19 vaccination, with sensitivity getting lower over time. In perspective, it may serve as a standardized tool in COVID-19 vaccine trials and in clinical care of immunosuppressed patients.},

In this study we set out to examine the efficacy of the hyperimmunoglobulin (HIG treatment in women with a recent primary CMV infection up to 14 weeks' gestation.
METHODS
Ongoing observational study at the prenatal medicine departments of Tuebingen, Bonn, Cologne and Erlangen, Germany as well as the laboratory Prof. Gisela Enders and Colleagues in Stuttgart, Germany and the Institute for Medical Virology at the University of Tuebingen. Enrollment criteria were the presence of confirmed, very recent primary CMV infection in the first trimester and a gestational age at first HIG administration of $\leq$ 14 weeks. The following inclusion criteria indicated a recent primary infection: low anti-IgG levels, low anti-CMV-IgG avidity in the presence of a positive CMV IgM test and no or just seroconversion anti-gB2-IgG-reactivity. The HIG administration (Cytotect CPcircledR, Biotest, Germany) was started as soon as possible within few days after the first visit in the four units. HIG was administered at 200 IU per kilogram bodyweight intravenously and repeated every two weeks until about 18 weeks' gestation. Maternal-fetal transmission at the time of amniocentesis was considered as relevant primary outcome measure. Multivariate logistic regression analysis was used to determine significant covariates that could be used for the prediction of maternal-fetal transmission.
RESULTS
149 pregnant women and 153 fetuses were treated. Median maternal age and weight was 32.0 years and 65.0 kg, respectively. Median gestational age at the time of the first referral to one of the four centers was 9.4 weeks. Median anti-CMV-IgG levels, the anti-CMV-IgM index and the CMV IgG avidity was 5.7 U/ml, 2.5, and 22.3%, respectively. Treatment with HIG started at a median gestational age of 10.6 weeks and ended at 17.9 weeks. Within this time frame, HIGs were administered on average 4 times. Amniocentesis was carried out at a median gestational age of 20.4 weeks. In 143 (93.6%) of the 153 cases, the fetus was not infected. Maternal-fetal transmission occurred in 10 cases (6.5%, [95% CI 3.2 - 11.7]). In the uni- and multivariate logistic regression analysis, only the level of the anti-IgM index was significantly associated with maternal-fetal transmission at the time of the amniocentesis. However, only four (40.0%) of the 10 cases with maternal-fetal transmission had an anti-IgM level above 11.4 which corresponds to the 95th centile of the pregnancies without transmission.
CONCLUSION
HIG is a treatment option to prevent maternal-fetal transmission in a case of a primary CMV infection. However, treatment is only beneficial in women with a very recent primary infection in the first trimester or during the periconceptional period, a timely start and an appropriate treatment interval.

However, only four (40.0%) of the 10 cases with maternal-fetal transmission had an anti-IgM level above 11.4 which corresponds to the 95th centile of the pregnancies without transmission.
CONCLUSION
HIG is a treatment option to prevent maternal-fetal transmission in a case of a primary CMV infection. However, treatment is only beneficial in women with a very recent primary infection in the first trimester or during the periconceptional period, a timely start and an appropriate treatment interval.

Dosing recommendations for the treatment of pregnancy-acquired toxoplasmosis are empirical and widely based on experimental data. There are no pharmacological data on pregnant women with acute Toxoplasma gondii infection under treatment with pyrimethamine (PY) and sulfadiazine (SA) and our study intends to tighten this gap.
METHODS
In this retrospective case-control study, we included 89 pregnant women with primary Toxoplasma infection (PT) treated with PY (50~mg first dose, then 25~mg/day), SA (50~mg/kg of body weight/day), and folinic acid (10-15~mg per week). These were compared to a group of 17 women with acute ocular toxoplasmosis (OT) treated with an initial PY dose of 75~mg, thereafter 25~mg twice a day but on the same SA and folinic acid regimen. The exact interval between drug intake and blood sampling and co-medication had not been recorded. Plasma levels of PY and SA were determined 14 $pm$ 4~days after treatment initiation using liquid chromatography-mass spectrometry and compared using the Mann-Whitney U test at a p textless 0.05 level.
RESULTS
In 23 PT patients (26%), SA levels were below 20~mg/l. Fifteen of these 23 patients (17% of all patients) in parallel presented with PY levels below 700~µg/l. Both drug concentrations differed remarkably between individuals and groups (PY: PT median 810~µg/l, 95% CI for the median [745; 917] vs. OT 1230~µg/l [780; 1890], p = 0.006; SA: PT 46.2~mg/l [39.9; 54.4] vs. OT 70.4~mg/l [52.4; 89], p = 0.015) despite an identical SA dosing scheme.
CONCLUSIONS
SA plasma concentrations were found in the median 34% lower in pregnant women with PT compared to OT patients and fell below a lower reference value of 50~mg/l in a substantial portion of PT patients. The interindividual variability of plasma concentrations in combination with systematically lower drug levels and possibly a lower compliance in pregnant women may thus account for a still not yet supportable transmission risk. Systematic drug-level testing in PT under PY/SA treatment deserves to be considered.},

Results: Against murine norovirus, the reduction factors~(RF;~RF mean~$pm$ standard deviation~log10 reduction of postsampling) for ethanol gel 86% v/v (RF 1.96~$pm$~0.64), ethanol 89.5% v/v (RF 2.49~$pm$~0.59)~and ethanol 72.4% v/v (RF 2.61~$pm$~0.50), were all significantly superior to that of~the reference solution. Conclusion: All three handrubs passed the criteria set out in prEN 17430 and exhibited excellent virucidal efficacy.

abstract = {BACKGROUND
After the introduction of a vaccine against B. pertussis the seasonal pattern with the highest number of infections in the spring to summer months changed. Recent studies from around the world suggest that B. pertussis infections again follow a seasonal pattern with increased incidence in summer.The aim of this study was to investigate whether respiratory infections caused by B. pertussis in the period from January 2008 to December 2018 also seasonally spread in Germany and if so, when the B. pertussis activity peaked.
METHODS
We tested 19,031 samples, mainly from Southern Germany, collected in the period from January 2008 to December 2018 using a Multiplex PCR assay. We assessed the number and proportion of samples positive for B. pertussis, stratified by patient's age and month. The seasonal distribution was investigated by plotting the average proportion of positive samples for each month.
RESULTS
We observed a B. pertussis seasonality with the highest number of positive samples in the months from June until September. In contrast, testing of samples for B. pertussis was requested most frequently in the period from October until March. The proportion of positive samples increased earlier in adolescents (age 10 to 19) than in other age groups.
CONCLUSIONS
We found a seasonality of B. pertussis infections in Germany, which differs from the time when most samples are sent in for testing of B. pertussis. Our study suggests that clinicians should be more aware of B. pertussis infections in the months from June until September to prevent further transmission to vulnerable family members.},

abstract = {INTRODUCTION
As of 22 June 2020, Severe Acute Respiratory Syndrome (SARS)-coronavirus (CoV)-2 has infected more than 8.95 million people worldwide, causing textgreater 468,000 deaths. The virus is transmitted through respiratory droplets and physical contact from contaminated surfaces to the mucosa. Hand hygiene and oral decontamination among other measures are key to preventing the spread of the virus. We report the in vitro virucidal activity of topical and oral povidone-iodine (PVP-I) products against SARS-CoV-2.
METHODS
Suspension assays were used to assess the virucidal activity of PVP-I against SARS-CoV-2. Products were tested at a contact time of 30~s for virucidal activity. Viral titres were calculated using the Spearman-K\"{a}rber method and reported as median tissue culture infectious dose (TCID50)/mL.
RESULTS
All four products [antiseptic solution (PVP-I 10%), skin cleanser (PVP-I 7.5%), gargle and mouth wash (PVP-I 1%) and throat spray (PVP-I 0.45%)] achieved $geq$ 99.99% virucidal activity against SARS-CoV-2, corresponding to $geq$ 4 log10 reduction of virus titre, within 30~s of contact.
CONCLUSION
This study provides evidence of rapid and effective virucidal activity of PVP-I against SARS-CoV-2. PVP-I-based products are widely available for medical and personal use for hand hygiene and oral decontamination, and could be readily integrated into coronavirus disease, COVID-19, infection control measures in hospital and community settings.},
