Abstract
Background: Primary autoimmune hypothalamitis is an exceptionally rare inflammatory condition of the hypothalamus. Its etiology, clinical presentation, and management are not well established, with significant overlap and distinctions from hypophysitis.
Material and methods: This study presents management and outcomes of patients with autoimmune hypothalamitis managed at a tertiary care centre. A literature review was also performed analyzing clinico-demographic, biochemical, radiological, and therapeutic characteristics.
Results: There were 4 cases of autoimmune hypothalamitis out of 2200 sellar-suprasellar lesions managed over the past decade at our centre. Case 1 presented with arginine vasopressin (AVP) deficiency and adipsia, showing partial radiological response to glucocorticoids. Case 2 presented with neuropsychiatric features, with limited improvement on therapy. Case 3 had panhypopituitarism with stable disease on imaging, while Case 4 had AVP deficiency and hypogonadism with no significant radiological or hormonal recovery post therapy. Literature review (n = 34) of all cases showed female predominance (88%), but minimal association with pregnancy (6%). Polyuria-polydipsia was the most common presentation (81%), followed by memory disturbances and/or confusion (35%). Secondary hypogonadism was most common (88%) hormone deficiency followed by hypocortisolism (85%) and AVP deficiency (82%). T2 hyperintensity was the most common feature (95%) on MRI. Glucocorticoids enabled partial radiological response in most cases (82%), with hormonal recovery being less common (18%). Adjunctive medical therapy was required in 54.1% cases (most commonly azathioprine). Surgery was primarily used for biopsy and adjunctive radiotherapy in 3 cases. FDG-PET demonstrated utility in diagnosis, systemic involvement and follow-up.
Conclusion: Autoimmune hypothalamitis remains a challenging diagnosis due to its rarity and overlapping features with other sellar pathologies. Histopathological evaluation or circulating antibodies can point towards the diagnosis. FDG-PET can be valuable in diagnosis and follow-up. Glucocorticoids are the mainstay of treatment, with partial radiological response commonly observed.
期刊介绍:
Well-established as a major journal in today’s rapidly advancing experimental and clinical research areas, Endocrine publishes original articles devoted to basic (including molecular, cellular and physiological studies), translational and clinical research in all the different fields of endocrinology and metabolism. Articles will be accepted based on peer-reviews, priority, and editorial decision. Invited reviews, mini-reviews and viewpoints on relevant pathophysiological and clinical topics, as well as Editorials on articles appearing in the Journal, are published. Unsolicited Editorials will be evaluated by the editorial team. Outcomes of scientific meetings, as well as guidelines and position statements, may be submitted. The Journal also considers special feature articles in the field of endocrine genetics and epigenetics, as well as articles devoted to novel methods and techniques in endocrinology.
Endocrine covers controversial, clinical endocrine issues. Meta-analyses on endocrine and metabolic topics are also accepted. Descriptions of single clinical cases and/or small patients studies are not published unless of exceptional interest. However, reports of novel imaging studies and endocrine side effects in single patients may be considered. Research letters and letters to the editor related or unrelated to recently published articles can be submitted.
Endocrine covers leading topics in endocrinology such as neuroendocrinology, pituitary and hypothalamic peptides, thyroid physiological and clinical aspects, bone and mineral metabolism and osteoporosis, obesity, lipid and energy metabolism and food intake control, insulin, Type 1 and Type 2 diabetes, hormones of male and female reproduction, adrenal diseases pediatric and geriatric endocrinology, endocrine hypertension and endocrine oncology.
