Serious complications of COVID-19 vaccines: A mini-review

Τhe most promising approach of fighting COVID-19 and restraining the course of this pandemic is indisputably the universal vaccination of the population with safe and effective vaccines. However, besides the common and usually mild side effects of the authorized vaccines, some rare, major adverse reactions are increasingly being reported worldwide during the post marketing surveillance phase of vaccines’ circulation, such as anaphylaxis, vaccine-induced thrombotic thrombocytopenia, myopericarditis and Guillain-Barré syndrome. Despite rare cases with complications from COVID-19 vaccines, the net benefit-risk ratio shows a clearly favorable balance towards COVID-19 vaccination for all age and sex groups. Vaccine adverse events should be identified early and monitored closely. As many aspects of these adverse effects remain still obscure for the medical community and the relevant stakeholders, it is also highly important to be promptly reported. Nonetheless, these complications should not constitute a reason to change the vaccine policy and further studies are needed to alleviate concerns and reluctance to COVID-19 vaccinations.

Angiotensin-converting-enzyme insertion/deletion polymorphism, ACE activity, and COVID-19: A rather controversial hypothesis. A case-control study

Accumulating data has shown a contribution of the renin‐angiotensin system in COVID‐19 pathogenesis. The role of angiotensin‐converting enzyme (ACE) insertion (I)/deletion (D) polymorphism as a risk factor in developing COVID‐19 disease comes from epidemiological data and is controversially discussed. We conducted a retrospective case‐control study and assessed the impact of ACE I/D genotype in COVID‐19 disease prevalence and severity. In 81 COVID‐19 patients explicitly characterized and 316 controls, recruited during the first wave of COVID‐19 pandemic, ACE I/D genotype, and ACE activity were determined. A generalized linear model was used and Poisson regression analysis estimated the risk ratios (RRs) of alleles and genotypes for disease severity. DD patients had almost 2.0‐fold increased risk (RR: 1.886, confidence limit [CL] 95%: 1.266–2.810, p = 0.0018) of developing a more severe disease when contrasted to ID and II individuals, as did D allele carriers compared to I carriers (RR: 1.372; CL 95%: 1.051–1.791; p = 0.0201). ACE activity (expressed as arbitrary units, AU/L) was lower in patients (3.62 ± 0.26) than in controls (4.65 ± 0.13) (p < 0.0001), and this reduction was observed mainly among DD patients compared to DD controls (3.97 ± 0.29 vs. 5.38 ± 0.21; p = 0.0014). Our results demonstrate that ACE DD genotype may predispose to COVID‐19 increased disease severity via a mechanism associated, at least in part, with the significant fall in their ACE activity. Our findings suggest a more complex pattern of synergy between this polymorphism and ACE activity in COVID‐19 patients compared to healthy individuals and set the grounds for large‐scale studies assessing ACE genotype‐based optimized therapies with ACE inhibitors and angiotensin receptor blockers.

Real-life evaluation of a COVID-19 rapid antigen detection test in hospitalized children

Rapid antigen detection (RAD) tests for the detection of SARS-CoV-2 are simpler, faster, and less expensive than the reverse-transcription polymerase chain reaction (RT-PCR) that is currently considered the gold standard for the diagnosis of coronavirus disease 2019 (COVID-19). The objective of this study was to determine the performance of the PANBIO COVID-19 Ag RAD (Abbott) test, a lateral flow immunoassay that detects the nucleocapsid protein, using as a reference RT-PCR method the Cobas®8800 System (Roche Diagnostics). This prospective study was conducted in a tertiary Children's Hospital and included individuals aged ≤16 years with COVID-19-related symptoms or epidemiological criteria for COVID-19. Two nasopharyngeal samples were collected to perform the PANBIO RAD test and RT-PCR. Of 744 children included, 51 (6.86%) had a positive RT-PCR result. The RAD test detected 42 of 51 PCR-positive children while there were no false-positive results. The overall sensitivity and specificity were 82.35% (95% CI, 71.9%-92.8%) and 100%, respectively. Sensitivity was >95% in symptomatic children. The assay performed poorly in asymptomatically infected children. In agreement with previous studies in adults, the PANBIO RAD test can be useful in screening for COVID-19 in children admitted with symptoms suggestive of the disease, especially in the first days of the illness.

Use of point-of-care molecular tests reduces hospitalization and oseltamivir administration in children presenting with influenza-like illness

Influenza is associated with increased morbidity, healthcare costs, hospitalization rates, and mortality in children. Rapid immunochromatography assay (ICA), a test with low sensitivity, is often used as point-of-care (POC) test. Recently, the rapid syndromic molecular test FilmArray has become available. This observational study aims to evaluate whether the use of FilmArray would decrease the use of antivirals and hospitalization rates among children presenting to the emergency room (ER) with influenza-like illness (ILI) symptoms. Nasopharyngeal swabs were prospectively collected from children, aged 0-16 years, presenting with ILI at the ER of a tertiary hospital during the peak endemic period. Patients were allocated to be tested by either FilmArray or ICA. The use of antivirals and hospitalization rates were noted. Logistic regression models were used to investigate the impact of testing methods on decision-making. Overall, 80 children were included (mean age: 5 years). Admissions were more likely to occur if an ICA test was performed (OR, 3.16; 95% CI, 1.01-9.82; p = .046). Oseltamivir administration was more likely among children who had undergone the ICA test (OR, 4.67; 95% CI, 1.06-20.43; p = .041). The implementation of rapid molecular test had no impact on complementary diagnostic testing or antibacterial prescription. The use of FilmArray significantly reduced both hospitalization and oseltamivir administration in children. Further knowledge on the use of POC tests is required to improve current management of children presenting with ILI and decrease associated healthcare costs.

Is Hepatobiliary Scintigraphy Sufficient to Diagnose Rotor Syndrome in a 3-Year-Old Boy?

Rotor syndrome (RS) is a benign, inherited, commonly misdiagnosed cause of conjugated hyperbilirubinemia whose identification prevents unnecessary invasive investigations. We present the case of a 3-y-old boy with phenotypic and laboratory findings of RS but negative genetic test results, whose diagnosis was confirmed by hepatobiliary scintigraphy.

Outcome of refractory to conventional and/or biologic treatment adult Still's disease following canakinumab treatment: Countrywide data in 50 patients

OBJECTIVE

To assess the efficacy and safety of the IL-1b inhibitor canakinumab in all adults with refractory Still's disease identified from the National Organization For Medicines for off-label drug use.

METHODS

In a retrospective longitudinal multicenter cohort of 50 patients (median age 39 years) with active Still's disease despite treatment with corticosteroids (n = 11), conventional and synthetic (n = 34) and/or biologic disease modifying anti-rheumatic drugs (n = 30), we assessed the efficacy of canakinumab 150-300 mg administered every 4 (n = 47) or 8 weeks (n = 3) as combination therapy or monotherapy (n = 7) during a median follow-up of 27 (3-84) months.

RESULTS

Α complete response was initially observed in 78% of patients within 3 months (median), irrespective of age at disease onset. A partial response was evident in 20%. One patient had resistant disease. Treatment de-escalation was attempted in 15 of 39 complete responders and a complete drug discontinuation in 21 patients for 8 months (median). Eleven patients (22%) relapsed during treatment, one during de-escalation process, and 11 after treatment discontinuation. Overall, 9 of 11 relapses were successfully treated with canakinumab treatment intensification or re-introduction. At last visit, 18% of patients were off treatment due to remission and 26% due to disease activity. Canakinumab had a significant corticosteroid sparing effect allowing weaning in 21 of 41 cases. Infections (20%, severe 4%) and leucopenia (6%) led to treatment cessation in one patient.

CONCLUSION

High rates of sustained remission were observed in this, largest so far, real-life cohort of adult patients with refractory Still's disease treated with canakinumab.

Effects of measles-containing vaccination in children with severe underlying neurologic disease

BACKGROUND

Measles outbreaks pose significant risk for those unvaccinated.

PATIENTS AND METHODS

Measles-containing vaccine was offered to unvaccinated children with severe neurologic diseases during a measles outbreak. Vaccination adverse events were reported by parents 30 days following vaccination. Long term effects were evaluated 12 months post vaccination.

RESULTS

Twenty-seven children were vaccinated (36 doses given). Half of parents (51.8%) reported no adverse events following immunization. Adverse events included afebrile seizures (6/36), fever alone (5/36) and febrile seizures (5/36). Two children required hospitalization. Quadrivalent measles-containing vaccine combined with varicella was associated with febrile seizures (p = 0.04). No child needed adjustment of the anti-epileptic treatment or exhibited developmental regression.

CONCLUSION

Ina series of children with prior severe neurologic disease, the safety-tolerability profile ofvaccines containing a measles vaccine component suggests that vaccination is justified. Main side effect was seizure aggravation in children with known epileptic disease.

Breastfeeding during the novel coronavirus (COVID-19) pandemic: guidelines and challenges

COVID-19 pandemic has raised questions on pregnant women and newborns' management. Guidelines, issued by most international agencies and national bodies, recommend rooming-in and direct breastfeeding. In the early days of this pandemic, breastfeeding practices have been challenged by fear among both parents and healthcare workers occasionally resulting in mother-newborn separation. We herein review current breastfeeding guidelines and discuss remaining questions and challenges. As we are facing the second wave of this pandemic, more information is gathered, especially regarding possible virus transmissibility through breastfeeding, enabling more definite instructions about breastfeeding practices.

Asian-Pacific perspective on the psychological well-being of healthcare workers during the evolution of the COVID-19 pandemic

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has led to significant strain on front-line healthcare workers.

AIMS

In this multicentre study, we compared the psychological outcomes during the COVID-19 pandemic in various countries in the Asia-Pacific region and identified factors associated with adverse psychological outcomes.

METHOD

From 29 April to 4 June 2020, the study recruited healthcare workers from major healthcare institutions in five countries in the Asia-Pacific region. A self-administrated survey that collected information on prior medical conditions, presence of symptoms, and scores on the Depression Anxiety Stress Scales and the Impact of Events Scale-Revised were used. The prevalence of depression, anxiety, stress and post-traumatic stress disorder (PTSD) relating to COVID-19 was compared, and multivariable logistic regression identified independent factors associated with adverse psychological outcomes within each country.

RESULTS

A total of 1146 participants from India, Indonesia, Singapore, Malaysia and Vietnam were studied. Despite having the lowest volume of cases, Vietnam displayed the highest prevalence of PTSD. In contrast, Singapore reported the highest case volume, but had a lower prevalence of depression and anxiety. In the multivariable analysis, we found that non-medically trained personnel, the presence of physical symptoms and presence of prior medical conditions were independent predictors across the participating countries.

CONCLUSIONS

This study highlights that the varied prevalence of psychological adversity among healthcare workers is independent of the burden of COVID-19 cases within each country. Early psychological interventions may be beneficial for the vulnerable groups of healthcare workers with presence of physical symptoms, prior medical conditions and those who are not medically trained.

FRI0543 BIRTH REGISTRY OF WOMEN WITH SYSTEMATIC LUPUS ERYTHEMATOSUSAND COURSE OF THE DISEASE DURING FIRST YEARS POST-PARTUM-THE GREEK EXPERIENCE

Background:

Pregnancy in women with SLE Systematic Lupus Erythematosus (SLE) has been related with adverse events both in the mother and the foetus.1Many studies have reported relapse of the disease during the pregnancy and post-labour, while others have not confirmed this finding.2To this end, most of these results originate from retrospective studies with patients of diverge ethnicities.

Objectives:

To record the Greek experience with pregnancies in mothers with SLE and their outcomes, as well as the course of the disease during first year post labor.

Methods:

This is a prospective, multicentre, observation study lasting three years. Women diagnosed with SLE who became pregnant consented to be monitored by their treating Rheumatologist. A structured questionnaire is used for monitoring at the beginning of pregnancy (positive pregnancy test) and at least every 3 months thereafter, depending on the course of the disease and pregnancy, until one year after childbirth.

Results:

A total 64 women and 81 pregnancies were recorded (1.27 pregnancies per patient). Patient’s age at conception was 32.8 ± 5.9 years (mean ± standard deviation). Thirteen patients (20.3%) had past history of nephritis. Regarding pregnancy outcomes, 62 (76.5%) pregnancies ended in live births, miscarriages during 1st, 2ndand 3rdtrimester occurred in 13 (16%). Six pregnancies were lost to followup. Prematurity occurred in 28 live births (45.1% in total), 26-32w (3.2%), 32-36w (22.5%), <37w (19.3%). No cases of preeclampsia occurred. Mean age of birth36.9 weeksand mean birth weight2750gr.The majority (72.5%) of deliveries were performed by caesarean section. In terms of disease activity, most of the women had mild disease at conception, (SLEDAI-2K: 2.67±2.69) that declined during 1st/2ndpregnancy trimester (SLEDAI-2K:1.91±2.09, 1.70±2.22)) but increased during the 1stand 2ndtrimester post labor (SLEDAI-2K: 2.47±4.29 and 2.52±3.2).

Conclusion:

This is the first Greek inception cohort with prospective monitoring of pregnant SLE patients. Adverse outcomes occur with prematurity being the most frequent. In our cohort disease activity tends to increase during 1stand 2ndtrimester post-labor without serious relapses. Vigilant monitoring during pregnancy and post-labour is advised.

FRI0493 THE INTERLEUKIN-1B INHIBITOR CANAKINUMAB FOR REFRACTORY STILL’S DISEASE: LONG-TERM EXPERIENCE IN 50 CONSECUTIVE PATIENTS

Background:

Interleukin-1 (IL-1) is a major mediator of the inflammatory cascade in Still’s disease and an established therapeutic target.

Objectives:

To assess the efficacy and safety of the IL-1b inhibitor canakinumab in adolescent and adult patients with refractory Still’s disease.

Methods:

We conducted a retrospective longitudinal outcome study of 50 consecutive patients aged 39 years (median, range 14-72), fulfilling the Yamaguchi disease classification criteria, with active disease despite treatment with corticosteroids (CS) (n=11) and/or methotrexate (n=9) and/or biologics (n=30) [tumor necrosis factor inhibitors (n=13), IL-6 blockade (n=7), abatacept (n=2), anakinra (n=24); ≥1 biologics (n=13)]. Canakinumab 150-300 mg was administered sc, starting every 4 (n=48) or 8 weeks (n=2), for a median of 24 months (range 3-84). Concomitant treatment included CS (n=41), methotrexate (n=12) and leflunomide (n=3).

Results:

Complete remission was initially achieved in 78% of patients within a median time of 3 months, irrespective of age at disease onset. Partial clinical and laboratory response was evident in 20%. Canakinumab was discontinued in one patient with resistant disease (primary failure) and in 6 out of 10 initial responders, who relapsed during treatment (secondary failure). Of 39 patients in complete remission, increase in drug administration interval and/or drug dose reduction was attempted in 7, of which only 1 relapsed, whereas drug discontinuation was attempted in 19 patients for a median time of 8 months (range 3-68), of which 8 relapsed. Overall, in half of all disease flares, canakinumab re-introduction or intensification was successful. Canakinumab had a significant CS sparing effect permitting weaning in 21 of 41 cases. Infections (20%, severe 4%) and leucopenia (6%) led to treatment cessation in one patient.

Conclusion:

In this largest so far real-life patient cohort with refractory Still’s disease, high rates of sustained remission were induced by canakinumab both in adolescent and adult patients.

Antenatal imaging and clinical outcome in congenital CMV infection: A field-wide systematic review and meta-analysis

OBJECTIVES

Postnatal outcome in fetuses with congenital cytomegalovirus infection (cCMV) varies from asymptomatic infection to severe neurodevelopmental impairment. Αntenatal biomarkers of long-term clinical outcome, have yet to be established. Α systematic review and meta-analysis was performed to examine whether prenatal cerebral ultrasonography (US) and magnetic resonance imaging (MRI) findings in cCMV fetuses may predict clinical outcome.

METHODS

PubMed and the Web of Science were systematically searched to identify studies reporting on any prenatal US and/or MRI imaging of fetuses with cCMV as well as their postnatal clinical outcome. All reported associations between imaging and postnatal clinical outcome were systematically extracted. Where appropriate, the reported associations were quantitatively synthesized within Bayesian random-effects meta-analyses.

RESULTS

A total of 1336 studies were screened to identify 26 eligible observational studies. Overall, 4181 fetuses were studied, of which 1518 had been diagnosed with cCMV. All studies performed fetal US while in 14 (54%) MRI was also performed. Studies substantially varied in timing of fetal imaging, reporting of abnormalities, definition of poor outcome and statistical analysis. Among studies reporting on statistical significance, 6/6 for US and 3/4 for MRI identified significant associations between imaging findings and outcome. In our meta-analyses, within isolated abnormalities, only microcephaly had greater than 95% probability of being associated with poor outcome (OR 26.7; 95% CI, 1.44-1464.5; I², 19%). Effect sizes for US were higher than those for MRI findings.

CONCLUSIONS

Although studies displayed significant heterogeneity in both methodology and analytical decisions, it became evident that when both prenatal cerebral US and MRI are normal the negative predictive value of poor outcome is high. This is important for clinicians when consulting pregnant women. Need to standardize practices and definitions become evident.

Risk of congenital cytomegalovirus infection in children born to women with IgG avidity in the grey zone during first trimester of pregnancy

INTRODUCTION

Cytomegalovirus (CMV) is the most common congenital viral infection and is regarded as the leading nongenetic cause of sensorineural hearing loss. Currently, international consensuses discourage prenatal screening of pregnant women. However, in few countries mainly in Southern Europe, screening of pregnant women for CMV infection is common practice. Management of women found with IgG+/IgM + and IgG avidity titers in the grey zone during first trimester causes significant stress to both families and health care workers.

PATIENTS AND METHODS

Pregnant women referred to our outpatient clinic with the diagnosis of acute CMV infection (IgM+/IgG+) during early pregnancy (gestational age ≤ 14 weeks) and IgG avidity in the grey zone were prospectively followed. The administration of CMV-HIG was offered and follow-up included fetal U/S, amniocentesis for CMV-DNA detection and MRI when appropriate. All neonates were examined by urine PCR and prospectively followed according to existing recommendations.

RESULTS

Ninety women (mean age 30.8 years) were retrospectively analyzed. Most (79.6%) received CMV-HIG. Four women terminated pregnancy (2 unrelated to CMV reasons and 2 because of CMV-positive amniotic fluid). Eighty-seven babies were born asymptomatic. Two newborns were diagnosed with congenital CMV infection. The overall transmission rate was 4.4%; 4.3 versus 5.6% for those receiving or not CMV-HIG. No adverse outcomes were detected during follow-up (median 24 months). Maternal age, parity, detection of maternal CMV-viremia upon diagnosis, delay between diagnosis and consultation, gestational week of first consultation, administration of CMV-HIG and number of doses were not associated with the risk of vertical CMV transmission.

DISCUSSIONS

Vertical transmission of CMV infection in pregnancies with acute CMV-infection and IgG avidity titers in the grey zone during first trimester was 4.4%, higher than that in infants born post nonprimary infection (NPI) during pregnancy. More powered studies are needed to prove a significant reduction in transmission using CMV-HIG.

Epidemiology, Microbiological and Clinical Features, Treatment, and Outcomes of Infective Endocarditis in Crete, Greece

Background

This study aimed to evaluate the epidemiology, clinical and microbiological features, treatment, and outcomes of infective endocarditis (IE) on the island of Crete, a region with high levels of antimicrobial resistance.

Materials and Methods

Medical records of all hospitalized patients diagnosed with IE at the University Hospital of Heraklion, Crete, Greece, from 1995 to 2015, were retrospectively reviewed. Patients who met the modified Duke's criteria for definite or possible IE were included.

Results

A total of 82 IE patients (median age 67 [range 21–86] years) were included. Most patients suffered from left-sided IE (94%), while most cases of infection occurred in native valves (53.6%). Systemic inflammatory response syndrome criteria were lacking in almost half of the patient population. The leading causative microorganism was Staphylococcus aureus, isolated in 24 cases (29%), followed by Streptococcus spp. in 15 (18%) and Enterococcus spp. in 12 (14.5%). A number of rare and difficult to treat microorganisms had been identified, such as Gemella morbillorum in four cases (4.5%), Streptococcus lugdunensis in two (2.5%) and Streptococcus pneumoniae in one (1%). One patient was serologically positive for Coxiella burnetii (1%). All patients received empirical antimicrobial treatment, proven appropriate in 39 blood culture-positive patients (56.5%). Thirteen (16%) patients were classified as culture negative. Seven patients (8.5%) were surgically treated. In-hospital death occurred in 9 patients (11%).

Conclusion

Changes in IE profile requires continuous epidemiological updates. Staphylococcus and Streptococcus spp. remain the most common etiologic agents. However, the presence of uncommon and/or difficult to treat pathogens raise concerns on the appropriate prophylaxis as well as empirical treatment.
