Thyroid Research in Bangladesh - Current Status and Future Directions

Thyroid disorders are among the most common endocrine diseases, including conditions such as hyperthyroidism, hypothyroidism, thyroid nodules, and thyroid adenomas. In recent decades, the incidence of these conditions has increased. Notably, cases of thyroid cancer, particularly papillary thyroid carcinoma, have risen modestly. Despite this increase, the mortality rate for thyroid cancer remains low, potentially due to overdiagnosis. Consequently, the decision between immediate surgical intervention and active surveillance for thyroid cancer treatment has become a prominent topic of discussion.[1] In addition, benign thyroid conditions, such as hyperthyroidism and hypothyroidism, continue to be the most common endocrine diseases globally. As research progresses, there has been a shift in focus and emerging areas of interest. Significant advancements have been made in understanding the mechanisms underlying thyroid diseases, leading to more personalized approaches in their diagnosis, treatment, and prevention. These developments enable patients with thyroid disorders to receive more precise therapies and achieve improved prognoses.[2] Thyroid disorders are a significant health concern in Bangladesh, with studies suggesting that up to 20%–30% of the general population may be affected.[3] Thyroid disease research has seen global contributions from 175 countries and regions. Among these, 54 nations have each published over 100 articles on the subject. Leading this scholarly output is the United States, with 16,120 publications and 678,255 citations, indicating both high productivity and significant impact. China follows with 10,565 publications and 141,486 citations, while Italy ranks third, contributing 6333 publications and 222,807 citations. Notably, France boasts the highest average citations per article[4] among the top 10 countries, reflecting the substantial influence of its research. In addition, China has the most recent average publication year, suggesting a strong focus on current research, closely followed by South Korea. Between 2000 and 2021, the volume of publications on thyroid disease research generally increased annually despite occasional fluctuations. The United States led in both publication count and citation frequency, highlighting its significant role in this field. In recent years, there has been a notable rise in thyroid disorder research from China and South Korea, possibly due to higher incidence rates and growing academic interest.[5,6] Among the top 20 institutions by publication volume, Harvard University distinguished itself with the highest number of publications and citations, collaborating with 222 prolific institutions and serving as a central hub for global research collaboration. In addition, 97% of the 397 leading authors in this domain are part of collaborative networks, indicating a high degree of cooperation among top researchers. Despite this, comprehensive epidemiological data on the prevalence and types of thyroid dysfunction in the country remain limited. Research output from Bangladesh in the field of endocrinology, including thyroid studies, has been minimal on the global stage. Between 1972 and 2021, Bangladesh contributed only 0.132% of global endocrine publications, though there has been a gradual increase in recent years.[7] In terms of clinical practice, the Bangladesh Endocrine Society has developed guidelines for diagnosing and managing thyroid diseases, including recommendations for screening thyroid function during pregnancy.[8] Looking ahead, there is a pressing need to enhance thyroid research in Bangladesh. This includes conducting large-scale epidemiological studies to accurately assess the burden of thyroid disorders, investing in research infrastructure, and fostering collaborations both nationally and internationally. Such efforts are essential to improve understanding, diagnosis, and management of thyroid diseases in the country. Even then, Selim et al. found an unsanitary level of compliance with established guidelines or recommendations by practicing physicians in Bangladesh.[9] Notably, discussions on the current status and future directions of thyroid research in Bangladesh are taking place in academic forums, such as the 7th International Conference of the Bangladesh Endocrine Society scheduled for 2024. Thyroid disorders are a significant health concern in Bangladesh, affecting a substantial portion of the population with conditions such as hypothyroidism, hyperthyroidism, goiter, and iodine deficiency disorders. Thyroid research in Bangladesh is evolving, and several key areas offer promising future directions: Promotion of research activities: Encouraging and supporting young endocrinologists to engage in research will enhance the understanding of thyroid disorders specific to the Bangladeshi context. This includes providing research grants, facilitating access to advanced training, and fostering a culture of scientific inquiry. Prevalence studies: Expanding epidemiological studies to assess the prevalence of thyroid disorders across different regions and demographics can provide a clearer picture of the public health impact Yazdaan HE, Jaya F, Sanjna F, Junaid M, Rasool S, Baig A, et al.

Cureus. 2023;15:e48961. doi: 10.7759/cureus.48961 Impact of lifestyle factors: Studying the influence of lifestyle changes, urbanization, and environmental factors on thyroid health could yield important insights Addressing environmental factors: Investigating environmental contributors, such as arsenic exposure, which may influence thyroid health in certain regions of Bangladesh, is essential for developing targeted public health interventions Iodine deficiency and supplementation: Ongoing studies on iodine status in various populations, including the effects of iodized salt programs, can inform public health initiatives Public awareness campaigns: Research on the effectiveness of educational campaigns can help improve awareness and early detection of thyroid disorders Impact of lifestyle factors: Studying the influence of lifestyle changes, urbanization, and environmental factors on thyroid health could yield important insights Thyroid cancer research: Increased focus on the incidence, risk factors, and outcomes of thyroid cancer, especially given rising rates, can guide screening and treatment protocols International collaboration: Partnering with regional and international endocrine societies can provide access to global expertise, research methodologies, and funding opportunities. The Bangladesh Endocrine Society’s affiliation with organizations such as the South Asian Federation of Endocrine Societies and the International Society of Endocrinology is a positive step in this direction Training and capacity building: Investing in training healthcare professionals in endocrinology can strengthen the overall approach to thyroid health in Bangladesh. By focusing on these strategic areas, Bangladesh can enhance its capacity to manage thyroid disorders effectively, improve patient outcomes, and contribute valuable insights to the global understanding of these conditions. In summary, thyroid disorders are a significant health concern in Bangladesh, affecting approximately one-fourth of the population. However, there is a considerable gap in understanding the actual prevalence of various thyroid conditions, including iodine deficiency disorders, hypothyroidism, hyperthyroidism, goiter, and thyroid malignancy. Addressing this gap through dedicated research initiatives and strategic planning is crucial for the effective management of thyroid health in the country. Financial support and sponsorship Nil.
