Hyperprolactinemia and Tuberculosis: An Atypical Presentation – Acase Study
Abstract
Abstract: Hyperprolactinemia diagnosis can be challenging due to various potentialcauses. Commonly, a prolactin level above 200-250 ng/ml indicatesprolactinomas. However, this may not always apply, as other causes,including tuberculosis affecting the pituitary, can lead to elevatedprolactin levels. Tuberculosis-induced pituitary involvement is rare andmainly detected through precise imaging, particularly in tropicaltuberculosis-endemic areas. Misidentification as a pituitary adenoma canresult in delayed diagnosis and treatment, causing enduring damage toboth the endocrine and nervous systems. This case study, a rarity inGuyana, was identified via histopathological studies, initially escapingdetection in advanced radiological assessments without signs ofextrapulmonary or pulmonary tuberculosis.
Objectives
Objective: · To highlight pitfalls in prolactin testing. · To elucidate the impact of tuberculosis on the pituitary gland. · To underscore the significance of considering tuberculosis as a cause ofprolactinomas, particularly in endemic regions.
Case
Case study.
Method
Methodology: This case study reviews relevant research papers, emphasizingtheimportance of considering tuberculosis as a cause ofprolactinomas,especially in endemic areas. It explores common causesofhyperprolactinemia and potential pitfalls in laboratory findingsofprolactin levels.
Results
Results: Endocrine and metabolic manifestations due to tuberculosisareinfrequent but can be severe and complex. Although theadvancedtreatment of Mycobacterium tuberculosis reduces endocrineglandinvolvement, it can affect any endocrine structure. Symptomsaffectingthe endocrine and metabolic systems may arise from theinfection, treatment, or physiological processes. Some patients mayexperienceimmunosuppression, increasing susceptibility to tuberculosis.Symptoms often resolve with anti-tuberculosis medication, while othersmay require hormonal therapy.
Conclusion
Conclusion: Diagnosing pituitary tuberculosis is challenging, often relyingonhistological or post-mortem discoveries. Clinicians shouldconsiderpituitary tuberculosis in patients with pituitary dysfunction,especiallyfrom endemic areas or with a positive TB diagnosis. Earlyrecognitionand treatment are crucial to prevent lasting endocrine andnervoussystem damage.
