Case report: Paradoxical manifestation of covid 19 induced thyroiditis in the unvaccinated patient.

ABSTRACT:

Introduction and importance

Subacute thyroiditis (SAT) is a self-limiting viral or post-viral thyroid illness with triphasic clinical history of thyrotoxicosis, hypothyroidism and restoration to normal thyroid function.COVID-19 have wide range of clinical manifestation involving both respiratory and non-respiratory symptoms. Subacute Thyroiditis is one of the emerging symptoms of COVID-19 infection. We reviewed various articles from different online platforms and found that viral antigen binds to HLA B35 molecules on the macrophages which activates cytotoxic T lymphocytes which damage the thyroid follicular cells by binding to ACE2 receptors.

Case

We presented a case of COVID-19 induced subacute thyroiditis in an unvaccinated male patient whose physical symptoms manifested in the second week of infection. He presented with History of difficulty breathing associated with increased perspiration, generalized body weakness.

Clinical findings and investigation

His clinical Findings and laboratory finding were suggestive of subacute thyroiditis.

Intervention and outcome

The patient had been followed for a period of 15 days and was treated effectively with steroids which improved his symptoms. He was also counseled for vaccination.

Project description:We report a case of overlooked Subacute Thyroiditis (SAT) potentially induced by the administration of a COVID-19 vaccine. This case prompted a thorough review of the existing literature to elucidate possible mechanisms by which immune responses to the COVID-19 vaccine might precipitate thyroid damage. The primary objective is to enhance the clinical understanding and awareness of SAT among healthcare professionals. Subacute thyroiditis is a prevalent form of self-limiting thyroid disorder characterized by fever, neck pain or tenderness, and palpitations subsequent to viral infection. The development of numerous SARS-CoV-2 vaccines during the COVID-19 pandemic was intended to mitigate the spread of the virus. Nevertheless, there have been documented instances of adverse reactions arising from SARS-CoV-2 vaccines, such as the infrequent occurrence of subacute thyroiditis. While the majority of medical practitioners can discern classic subacute thyroiditis, not all cases exhibit typical characteristics, and not all systematic treatments yield positive responses. In this study, we present a rare case of subacute thyroiditis linked to the administration of the SARS-CoV-2 vaccine. A previously healthy middle-aged female developed fever and sore throat 72 h post-inoculation with the inactivated SARS-CoV-2 vaccine. Initially attributing these symptoms to a common cold, she self-administered ibuprofen, which normalized her body temperature but failed to alleviate persistent sore throat. Suspecting a laryngopharyngeal disorder, she sought treatment from an otolaryngologist. However, the pain persisted, accompanied by intermittent fever over several days. After an endocrinology consultation, despite the absence of typical neck pain, her examination revealed abnormal thyroid function, normal thyroid antibodies, heterogeneous echogenicity on thyroid ultrasonography, and elevated levels of Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP). These findings led to a consideration of the diagnosis of SAT. Initially, she was treated with non-steroidal anti-inflammatory drugs (NSAIDs) for her fever, which proved effective, but her neck pain remained uncontrolled. This suggested a poor response to NSAIDs. Consequently, steroid therapy was initiated, after which her symptoms of fever and neck pain rapidly resolved.
