About Coronavirus and Coronavirus Disease 2019
Coronavirus belongs to a large family of single-stranded RNA viruses. Initially, the new virus was called 2019-nCoV. Later, it was renamed as SARS-CoV-2 virus as it is very similar to the one that caused the SARS outbreak (SARS-CoVs) in 2002–2003. Disease caused by this virus is called as coronavirus disease 2019 (COVID-19).
COVID-19 can spread from one person to another through small droplets from the nose or mouth when a person with COVID-19 coughs or exhales. Fever, tiredness, and dry cough are the most common symptoms of COVID-19. Some patients may also have aches and pains, nasal congestion, runny nose, sore throat, or diarrhea. Usually, these symptoms are mild and begin gradually. About 80% of patients recover from the disease without any special treatment. Around one out of every six people who gets COVID-19 becomes seriously ill and develops difficulty in breathing. Elderly people, and those with medical conditions such as hypertension, cardiac problems or diabetes, chronic obstructive airway disease, are more likely to develop serious illness.
Thyroid Disorders in India
Thyroid diseases are common worldwide. In India too, there is a significant burden of thyroid diseases.
Among adult people in India, the prevalence of hypothyroidism is 10.95% (approximately 1 in 10 adults). The prevalence of subclinical hypothyroidism was also high in this study, the value being 8%Congenital hypothyroidism (CH) is the most common cause of preventable mental retardation. A study conducted by the Indian Council of Medical Research between 2007 and 2012 reported the overall incidence of CH to be 1:1130 newbornsIn India, the overall prevalence of hyperthyroidism is reported to be 0.6%–1.9% which can be overt or subclinical,In India, the age-adjusted incidence rates of thyroid cancer per 100,000 are about 1 for male and 1.8 for female and the most common type of thyroid cancer is papillary thyroid cancer, followed by follicular thyroid cancerPatients with hypothyroidism show a greater propensity for comorbidities and complications as compared to the general population
Diabetes: Hypothyroidism and diabetes mellitus (DM) are the most common endocrine disorders in clinical practice and are often associated in the same individual. The prevalence of hypothyroidism in type 2 DM (T2DM) in India was found to be about 24%Dyslipidemia: Hypothyroidism has significant impact on lipids as well as other cardiovascular risk factors. Fifteen percent of dyslipidemics may have hypothyroidism as underlying causeHypertension: Hypothyroidism is a remediable cause of hypertension. The prevalence of hypothyroidism in T2DM and hypertension in India was found to be about 33%.
Hypothyroidism and Coronavirus Disease 2019
There is no information on how it affects individuals with hypothyroidism. As such patients with hypothyroidism are not at increased risk of viral infections in general and there is no association between hypothyroidism and severity of viral infectionIt is recommended that patients with hypothyroidism should continue taking their levothyroxine treatment as suggestedHypothyroidism in pregnancy:
There is no evidence that suggests that pregnant women are at increased risk of COVID-19Pregnancy alters the body's immune system and response to viral infections in general, which can occasionally be related to more severe symptoms, and this will be the same for COVID-19Pregnant patients with hypothyroidism should continue taking levothyroxine treatment.
Patients with hypothyroidism and other comorbidities:
Most distinctive comorbidities reported with COVID-19 patients are diabetes, coronary heart diseases, cerebrovascular disease, and hypertensionDiabetes: Both diabetes type 1 and 2 can increase risk of contraction of COVID-19 due to immune dysfunctionPatients with hypothyroidism and other comorbidities such as diabetes, cardiac disease, and hypertension are at high risk for severe COVID-19 infection and such patients need to take more precautions.
Thyrotoxicosis and Coronavirus Disease 2019
There is no information on how it affects individuals with thyrotoxicosis. However, uncontrolled thyrotoxicosis may be at higher risk of complications (such as thyroid storm) from any infection. It is recommended that patients with thyrotoxicosis continue taking their thyroid medication(s) to reduce this riskAntithyroid drugs (ATDs) are not known to increase the risk of infection, unless they result in neutropenia, which is very rare. Patients on ATDs are not at higher risk of contracting COVID-19 or of developing more severe disease in the event of contracting the infectionPatients on corticosteroids or immunosuppressive agents for thyroid eye disease are more susceptible and are at high risk of severe illness from COVID-19, and such patients need to take more precautionsAny nonurgent surgeries or procedures for definitive treatment for thyrotoxicosis should be postponed
Thyroid Cancer and Coronavirus Disease 2019
There is no evidence that patients who have recently had radioiodine therapy or thyroid surgery for thyroid cancer are at increased risk of COVID-19All elective surgeries for thyroid cancer should be postponedPatients on suppressive doses of levothyroxine should continue their current dose. Being on suppressive dose of levothyroxine does not increase the risk of COVID-19 infection.
Recommendations for Thyroid Function Test in Patients With Coronavirus Disease 2019 Infection
In COVID-19 patients with existing thyroid disease and on thyroid medications, if there is no indication, thyroid function test (TFT) should not be repeatedIn COVID-19 patients admitted in the intensive care unit, routine TFT is not recommended. There is no benefit of levothyroxine treatment in patients with euthyroid sick syndrome.
Protective Measures to Avoid Infection
Patients should continue taking prescribed medicationsIt is recommended that patients should have adequate supply of medications but should avoid overstockingRegularly and thoroughly clean hands with an alcohol-based hand rub or wash them with soap and waterAvoid touching eyes, nose and mouthKeep a distance of at least 1 m from people with a cough, cold, or fluPatients should adhere to social distancing guidelines.
