Time-Lag Between Symptom Onset and Diagnosis of Subacute Thyroiditis – How to Avoid the Delay of Diagnosis and Unnecessary Overuse of Antibiotics

Horm Metab Res DOI: 10.1055/a-1033-7524Clinical symptoms of subacute thyroiditis (SAT) may be misleading and the proper diagnosis is significantly delayed, and many unnecessary therapeutic methods are used, including application of antibiotics. The purpose of the study is to analyze the reasons and frequency of delayed SAT diagnosis and unnecessary antibiotic treatment and to propose a simple algorithm to facilitate the diagnosis and prevent antibiotic abuse. Sixty-four SAT patients were divided into groups depending on the period of time from the first symptoms of SAT to diagnosis and on the unnecessary use of antibiotics. Data from medical history and laboratory test results were analyzed for individual groups to determine the reasons for delayed diagnosis and incorrect treatment. In 73% of patients, the diagnosis was delayed from over two weeks up to six months. Among 62 patients who provided data on antibiotic use, 29 (46.77%) were treated with one or more antibiotics due to SAT symptoms. Fever, preceding infection, increased C-reactive protein (CRP), and WBC were characteristic for the antibiotic treated group. Fever, preceding infection, increased CRP and WBC are typical for both SAT and infection and are the main symptoms leading to misdiagnosis and unnecessary antibiotic treatment in SAT. Thus, in all patients with neck pain or other SAT-like symptoms, thorough clinical examination of the neck is mandatory. When firm and/or tender thyroid nodule/goitre is present and ...
