PRES update regarding COVID-19 vaccination in children with rheumatic diseases

June 2021

Covid-19 in rheumatic patients

In general, the occurrence and clinical presentation of COVID-19 among children with rheumatic diseases (RD) do not differ from that of the general population; with the primary risk of cardiovascular diseases. Studies analyzing the risk-factors for hospitalization among 3,000 adult patients with RD from 40 countries, based on data from the Global Rheumatology Alliance, found an increased risk for hospitalization (46%) and death (9%) among SLE and vasculitis patients. The major risk-factors for hospitalization were history of cardiovascular disease, Afro-American, Hispanic or Asian origin, and prednisone dose of > 10 mg/day. These studies suggested a protective role of TNF inhibitors and/or synthetic DMARDs regarding hospitalization (1-3).

Covid-19 in pediatric rheumatic  patients

The European Registry collected data on 376 pediatric RD patients infected with COVID-19; the majority had JIA, 164 poly-articular and 115 oligo-articular subtypes. Initial outcome data from the registry are very reassuring, with only 1 in 20 patients hospitalized. Due to the database design and inherent reporting bias, this is likely an overestimate; suggesting that overall outcomes among this population appear to be generally good, with mild infection. As more reports are added to the database, further exploration of drug- and disease-specific outcomes will become available (4).

Covid-19 complications in children without RD

Regarding healthy children, multisystem inflammatory syndrome (MIS-C) resembling Kawasaki disease was described following COVID-19 (5), in most cases involving the heart with multisystem inflammation, shock and multi-organ failure (6).

Chronic COVID-19 syndrome was described in children, similar to what is seen in adults. Data from an Italian registry describe that more than half of the children recovering from COVID-19 had at least one ongoing symptom 120 days after the disease, and 43% experienced symptoms during daily activities. Major symptoms were tiredness, musculoskeletal pain, headache, insomnia, difficulty in breathing and palpitations, similar to those observed in the adult population (7). Data from the UK show that 13% of children ages 2-11 years and 14% of children ages 12-16 years had ongoing symptoms 5 weeks after their primary COVID-19 disease. This means that 1 of every 7-8 children with COVID-19 had ongoing symptoms (8).

A review summarizing data from several countries, analyzed 1,475 cases of children hospitalized with COVID-19. Among them, 615 (42%) had moderate or severe disease (9). Still, the disease is present in children, and hospitalization in adolescents 12-17 years was reported (10).

Currently, as COVID-19 cases are declining in some countries, primarily due to high vaccination rates in adults, the disease age distribution has changed: the highest COVID-19 incidence is seen in children and adolescents.

In addition, closing schools and kindergartens during the pandemic caused psycho-social and educational harm to children and adolescents, including anxiety, eating disorders, behavioral changes, decreased ability to study and concentrate, and increased violent and delinquent behaviors (11).

All the above suggest significant morbidity in children due to the pandemic, and might affect vulnerable pediatric patients with RD.

As the pandemic is ongoing, it is possible that COVID-19 cases may increase substantially in the setting of low vaccination rates and/or high transmissibility of new variants (for example, the new delta variant), affecting the unvaccinated pediatric population.

Covid-19 vaccines

In late 2020, the results of the Phase 1/2 and Phase 3 research on the efficacy and safety of vaccines developed by Pfizer (BNTb262) and Moderna (mRNA-1273) were published; reporting an efficacy of about 95%. Cumulative data continue to show efficacy and safety.

The EULAR COVID-19 Vaccination (COVAX) Registry is an observational registry that includes 1,519 adult patients with rheumatic and musculoskeletal diseases who were vaccinated against COVID-19. The safety profiles for COVID-19 vaccines in RD patients were reassuring. Most adverse events were the same as those in the general population: non-serious and involved short-term local and systemic symptoms. Only 0.1% reported severe adverse events. Most patients tolerated vaccination well, with rare reports of RD flare (5%; 1.2% severe) (12).

A large, prospective, multicenter study investigated immunogenicity, efficacy, and safety of the COVID-19 vaccination among 686 adults with RD and 121 controls. Vaccination resulted in an adequate immunogenic response with an acceptable safety profile in most patients with RD. Immunogenicity was severely impaired by rituximab and mildly impaired by methotrexate. Post-vaccination disease activity remained stable in most patients (13). A study examined the humoral response of 264 adult rheumatic patients following vaccination. A good humoral response was seen in 86%, with minor vaccine-related side-effects and no effect on the rheumatic disease (14).

These studies and additional data confirm that most DMARDs can be safely continued during vaccination. Withholding treatment with mycophenolate and abatacept, especially when combined with methotrexate, may be considered.

Clinical trial data (15), as well as data from a vast vaccination effort in Israel (16) show that vaccination of people 16 years and older is safe and has excellent efficacy, around 95% in preventing disease.

In a multinational, placebo-controlled trial with 2,260 adolescents, the immunogenicity, efficacy, and safety profiles observed in children ages 12-15 was similar to that of young adults. Adverse events were mild, mainly local reactions, pain at the injection site. Systemic side effects – mainly weakness, headache and chills were mild and resolved within 24-48 hours. No major side effects were reported (17).

In addition to preventing COVID-19, the vaccine prevented asymptomatic infections with an efficacy of 80%-90% (18) and reduced the viral load (19). This means that in addition to its excellent effect on reducing the disease, the vaccine limits the infective ability of the virus.

Based on clinical studies, several regulatory agencies extended approval for the vaccine to the age of 12, including authorities in Canada, USA-Advisory Committee on Immunization Practices (ACIP) (FDA approval), the UK, and the European Union EMA (20-22).

Vaccine and Myocarditis

There are reports of increased risk for myocarditis following vaccination (23-25). These are rare, given the hundreds of millions of vaccine doses administered, and have been reported administration of the mRNA COVID-19 vaccine, particularly amongst male adolescents and young adults more often after getting the second dose, and typically within several days after COVID-19 vaccination. Most patients responded well to treatment and rest, and had an excellent outcome. In 95% of cases, the symptoms were mild and resolved quickly. According to the Centers for Disease Control and Prevention (CDC), 300 cases of myocarditis and pericarditis (inflammation of the heart) were documented among the 20 million adolescents and young adults vaccinated in the USA (23). From extrapolation of the known reported rate of myocarditis in the 16-19 years old age group, the risk is about 1:6,000 in boys after receiving the second dose. In 95% of cases, symptoms are mild and resolve quickly. The CDC and ACIP continues to recommend COVID-19 vaccination for everyone 12 years of age and older, within the context of COVID-19 illness and related, possibly severe complications (23).

Conclusions

To summarize, it seems that the vaccine is as safe and effective for children with rheumatic diseases, as it is among the healthy pediatric population. It seems that despite the changing variants of the virus, the Covid-19 vaccine is still highly effective. Data are still being gathered daily, but so far there is no evidence of disease flare following vaccination. The risk for myocarditis is low. Vaccination should be considered for each child separately, based on the known COVID-19 status in a specific country. For children recovering from COVID-19, vaccine can be given no sooner than 3 months after the disease resolved.

 

Summary of PRES recommendations

•       The risk and morbidity of acquiring COVID-19 is relatively similar among healthy children and those with rheumatic diseases.

•       The new COVID -19 vaccines are approved by various health authorities for patients 12 years of age and older, and are recommended for pediatric rheumatic patients, as well.

•       It is recommended to vaccinate patients 12 years of age and older with low disease activity or those in remission, who are treated with methotrexate and biologic therapies.

  • When using prednisone above 20 mg/day or above 0.5mg/kg/day consult the rheumatologist.

•       It is advised to consult your pediatric rheumatologist to assess your disease activity and medications before deciding about vaccination.

•       It is important to establish registries regarding the efficacy, immunogenicity and safety of COVID-19 vaccines for patients with pediatric rheumatic diseases.

•       The PReS vaccination study group is conducting an ongoing registry study that aims to evaluate the safety and immunogenicity of the COVID-19 vaccines among patients with childhood RD. So far there are no safety concerns following available data on about 100 patients.

•       It is advisable to adhere to the annual flu vaccine however; the influenza vaccine should not be given together with the COVID-19 vaccine (best 2 weeks apart).

•       The vaccine will most likely protect the patient from getting a severe course of COVID-19, but it is still possible that vaccinated people can carry the virus and be contagious to others. Therefore, vaccinated patients should still wear masks and practice physical distancing, according to the local health guidelines.

•       A child who has recovered from COVID-19 can receive a vaccine at least 3 months after the day of full recovery. This is valid for the first vaccine dose as well as the second dose. In situations where a child had COVID-19 after receiving the first dose, the second dose can be given at least 3 months following the day of full recovery.

  • Following MISC it is suggested to consider vaccination according to the local health authorities

PRES update regarding COVID-19 vaccines in pediatric rheumatic patients

(Published on 30 December 2020)

  • The risk and morbidity of acquiring COVID-19 is relatively similar among healthy children and those with rheumatic diseases.
  • The new COVID -19 vaccines are approved by various health authorities for patients 16 years of age and older, and are recommended for pediatric rheumatic patients above those ages.
  • It is recommended to vaccinate patients 16 years of age and older with low disease activity or those in remission, who are treated with methotrexate and biologic therapies.
  • It is advised to consult your pediatric rheumatologist in order to assess your disease activity and medications before making a decision regarding vaccination.
  • It is important to establish registries regarding the efficacy and safety of COVID-19 vaccines for patients with pediatric rheumatic diseases.
  • It remains important to be vaccinated against influenza; however, the influenza vaccine should not be given together (best 2 weeks apart) from the COVID-19 vaccine.
  • Vaccine will most likely protect the patient from getting severe course of COVID-19, but it is still possible that vaccinated person could carry the virus and be contagious to others. Therefore, vaccinated patients should still be wearing masks and practicing physical distancing.

 

Updated PRES recommendations for coronavirus outbreak

(Update: 21 September 2020)

1. Be updated and follow your country’s Ministry of Health/National Public Health Care Body’s recommendations.

2. Ensure you meticulously follow all hygiene recommendations.

Simple measures are likely to help preserve your health and that of your family and friends:

•           Wear a mask. Practice social distancing. At least 1.5 meter is recommended

•           Avoid touching your face.

•           Coughing or sneezing should be into an elbow or tissue paper and the latter should be discarded safely.

•           Wash your hands very regularly for at least 20 seconds using soap and water. Dry hands thoroughly afterwards.

•           Use disposable tissues.

•           We should greet each other without shaking hands, and avoid hugs.

3. Current available scientific data shows lower disease incidence, and morbidity among children. Therefore, we recommend at present that children with rheumatic diseases on medication continue all therapies as usual.

Do not stop taking your medications, including methotrexate (MTX) and biologics, without consulting your rheumatologist. This may cause a flare of your rheumatic disease.

Be aware that at this stage, recommendations may vary from one country to the other.

4. If you are on corticosteroid therapy, consult your rheumatologist regarding possible dose adjustment

5. Follow your country’s Ministry of Health/National Public Health Care Body’s/Ministry of Education recommendations regarding school participation and activities.

Current knowledge shows that patients receiving MTX or biologics (anti TNF, anti IL-1, anti IL-6) as a monotherapy or a combination of MTX and anti-TNF medications, or Mycophenolate, cyclosporine, are not considered to be at increased risk of contracting Corona or having a severe disease. They can attend school, educational and social activities with the precautions mentioned above.

Consider that paediatric rheumatic patients might be at higher risk for COVID-19 if they are receiving corticosteroids >0.5 mg/kg/d or immunosuppressive treatment, such as cyclophosphamide, and rituximab. In this case, consult your paediatric rheumatologist.

6. Patients in isolation or quarantine (without symptoms) should continue therapy as usual.

For asymptomatic patients who tested positive for COVID-19, ask your physician if you should continue or stop treatment. Based on current knowledge, you can probably continue therapy.

7. In case of fever and suspicion of an infectious disease, follow your country’s advice for access to healthcare and to test for COVID-19. In the meantime, stop MTX and, if taking biologics, contact your treating rheumatologist for guidance.

If you are symptomatic and positive for COVID-19, consult your physician regarding continuing medications.

8. In the event that you have a routine rheumatology appointment consider to ask your primary care physician, or rheumatologist if this is essential, or if it can be performed by telephone or another remote device ("telemedicine"). This facility may vary in availability across different health care settings.

9. Everyone, including patients with paediatric rheumatic diseases, avoid unnecessary travel and crowds.

10. Wishing you good health and that we should all be back on our regular track soon.

There are 2 running updated registries for COVID-19. See below:

Physician registry
PRES encourages all paediatric rheumatologists who have seen or are aware of a case of COVID-19 infection in any child with a pre-existing rheumatic disease to report it here https://www.eular.org/eular_covid19_database.cfm
