Challenges in autoimmune polyendocrine syndrome type 2 with the full triad induced by anti-programmed cell death 1: a case report and review of the literature.

Background: Immune checkpoint inhibitors (ICPis) induce autoimmune diseases, including autoimmune polyendocrine syndrome type 2 (APS-2), which is defined as a combination of at least two of the following endocrinopathies: autoimmune thyroid disease, type 1 diabetes, and Addison's disease. Cases with the full triad are rare. We present a case of an elderly woman who developed APS-2 with the complete triad shortly after starting anti-programmed cell death 1 (anti-PD1) treatment and review the related literature. Case: A 60-year-old woman, without any personal or family history of autoimmune and endocrine diseases, started the immunotherapy of anti-PD1 (camrelizumab) for squamous cell carcinoma of the urethral meatus. She developed primary hypothyroidism with elevated antibodies to thyroid peroxidase and thyroglobulin after 25 weeks of treatment, and developed primary adrenal insufficiency with adrenal crisis and fulminant type 1 diabetes with ketoacidosis after 45 weeks. Therefore, this patient met the diagnosis of APS-2 and was given multiple hormone replacement including glucocorticoid, levothyroxine and insulin therapy. Continuous improvement was achieved through regular monitoring and titration of the dosage. Conclusions: Different components of APS-2 may appear at different time points after anti-PD1 administration, and can be acute and life-threatening. A good prognosis can be obtained by appropriate replacement with multiple hormones. Insights: With the clinical application of ICPis to APS-2, the complexity of its treatment should be paid enough attention.

VKH with APECED in a Two-Year-Old Child: A Rare Concomitant Diagnosis in an Unprecedented Age.

PURPOSE: To present a case of Vogt Koyanagi Harada (VKH) associated with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) in a two-year-old. CASE PRESENTATION: A two-year-old type 1 diabetic with hypothyroidism presented with impaired fixation. Ocular examination revealed right vitritis, choroiditis, a hyperemic disc, and an area of exudative detachment. At the same time, there was no fundus view in the left eye, and ultrasonographic assessment revealed vitritis and a thickened choroid. Patient developed sunset glow fundus with alopecia, poliosis and vitiligo and a diagnosis of complete VKH with APECED was made. CONCLUSION: APECED is a rare endocrine disorder and has been reported to be associated with VKH twice. Likewise, VKH is commonly present in much older patients; this is the first time ever to be diagnosed in a two-year-old child.

Identification of AIRE pathogenic variants ends diagnostic odyssey for Saudi child with infantile-onset keratoconjunctivitis as an early sign of autoimmune polyglandular syndrome type1; a case report.

PURPOSE: Chronic keratoconjunctivitis is a rare presentation of autoimmune polyglandular syndrome type 1 (APS-1) during the first year of life. Herein, We report a case of a 10-month-old baby girl with chronic bilateral keratoconjunctivitis, corneal scarring and neovascularization that was treated initially with topical immunosuppressants. METHODS: Detailed ophthalmological assessment followed by molecular testing using whole exome sequencing. RESULTS: In addition to the severe chronic bilateral keratoconjunctivitis, corneal scarring and neovascularization, patient weight was found to be low than 10th percentile. Further genetic testing revealed autoimmune regulator (AIRE) gene variant that was only reported once in the literature confirming the diagnosis of APS-1. Further workup detected hypoparathyroidism that was treated with calcium supplementation. CONCLUSION: Our case represents the importance of multidisciplinary services and highlights the role of genetic testing in diagnosing such syndromic cases. We reviewed previous reports and found that available treatment for ocular involvement is usually nonsatisfactory; however, early detection and referral by ophthalmologists could result in treating previously undetected endocrine disorders that can be life threatening if left untreated.

Autoimmune Polyglandular Syndrome Type 3 Complicated with IgG4-related Disease.

A 52-year-old Japanese woman developed type 1 diabetes mellitus (type 1 DM) at 41 years old. She became complicated with Hashimoto's disease and showed swelling of both submandibular glands, which was diagnosed as IgG4-related disease (IgG4-RD). This is a rare case of a Japanese patient with autoimmune polyglandular syndrome type 3A (APS-3A) coexisting with autoimmune thyroid disease (AITD) and type 1 DM complicated by IgG4-RD. Bilateral submandibular gland resection was successfully performed without steroid therapy. We discuss the possibility that the immunological pathogenic mechanisms of APS-3A and IgG4-RD are related.

Evaluation of a large set of patients with Autoimmune Polyglandular Syndrome from a single reference centre in context of different classifications.

PURPOSE: To characterize patients with APS and to propose a new approach for their follow-up. Query ID="Q1" Text="Please check the given names and familynames." METHODS: Monocentric observational retrospective study enrolling patients referred to the Outpatients clinic of the Units of Endocrinology, Diabetology, Gastroenterology, Rheumatology and Clinical Immunology of our Hospital for Autoimmune diseases. RESULTS: Among 9852 patients, 1174 (11.9%) [869 (73.9%) female] were diagnosed with APS. In 254 subjects, the diagnosis was made at first clinical evaluation (Group 1), all the other patients were diagnosed with a mean latency of 11.3 ± 10.6 years (Group 2). Group 1 and 2 were comparable for age at diagnosis (35.7 ± 16.3 vs. 40.4 ± 16.6 yrs, p = .698), but different in male/female ratio (81/173 vs 226/696, p = .019). In Group 2, 50% of patients developed the syndrome within 8 years of follow-up. A significant difference was found after subdividing the first clinical manifestation into the different outpatient clinic to which they referred (8.7 ± 8.0 vs. 13.4 ± 11.6 vs. 19.8 ± 8.7 vs. 7.4 ± 8.1 for endocrine, diabetic, rheumatologic, and gastroenterological diseases, respectively, p < .001). CONCLUSIONS: We described a large series of patients affected by APS according to splitters and lumpers. We propose a flowchart tailored for each specialist outpatient clinic taking care of the patients. Finally, we recommend regular reproductive system assessment due to the non-negligible risk of developing premature ovarian failure.

IPEX syndrome from diagnosis to cure, learning along the way.

In the past 2 decades, a significant number of studies have been published describing the molecular and clinical aspects of immune dysregulation polyendocrinopathy enteropathy X-linked (IPEX) syndrome. These studies have refined our knowledge of this rare yet prototypic genetic autoimmune disease, advancing the diagnosis, broadening the clinical spectrum, and improving our understanding of the underlying immunologic mechanisms. Despite these advances, Forkhead box P3 mutations have devastating consequences, and treating patients with IPEX syndrome remains a challenge, even with safer strategies for hematopoietic stem cell transplantation and gene therapy becoming a promising reality. The aim of this review was to highlight novel features of the disease to further advance awareness and improve the diagnosis and treatment of patients with IPEX syndrome.

A novel missense mutation in the AIRE gene underlying autoimmune polyglandular syndrome type 1.

The immune regulator gene AIRE plays an essential role in the establishment of immune tolerance and the prevention of autoimmunity. This transcription factor plays a critical role in promoting self-tolerance in the thymus by regulating the expression of a large number of self-antigens that share the common feature of being tissue-restricted in their expression pattern in the periphery. Dysfunction of AIRE in humans causes a rare disease, autoimmune polyglandular syndrome type 1 (APS1), characterized by an autoimmune response against peripheral tissues, particularly endocrine tissues. Although a few dominant mutations have been described, the inactivation of AIRE is usually caused by recessive mutations. Recent data suggests that alterations in AIRE function contribute not only to APS1 but also to more common forms of autoimmune disease. Here, we present a previously unreported missense mutation (NM_000383.2:c.260 T > C) in exon 2 of the AIRE gene, predicted to cause the substitution (p.(Leu87Pro)) in the CARD domain of the AIRE protein. When inherited in conjunction with another dysfunctional AIRE allele, this mutation was associated with immune dysregulation in a pediatric patient. The presence of hypergammaglobulinemia, malabsorption syndrome, ectodermal dysplasia, mucocutaneous candidiasis, vitiligo, and hypothyroidism as well as the presence of multiple autoantibodies allowed us to confirm an APS1 diagnosis.

A case report of anti-GAD65 antibody-positive autoimmune encephalitis in children associated with autoimmune polyendocrine syndrome type-II and literature review.

Background: Glutamic acid decarboxylase (GAD) is the rate-limiting enzyme for the synthesis of gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the central nervous system. Antibodies against glutamic acid decarboxylase (GAD) are associated with various neurologic conditions described in patients, including stiff person syndrome, cerebellar ataxia, refractory epilepsy, and limbic and extra limbic encephalitis. While there are few case reports and research on anti-GAD65 antibody-associated encephalitis in adults, such cases are extremely rare in pediatric cases. Methods: For the first time, we report a case of anti-GAD65-positive autoimmune encephalitis associated with autoimmune polyendocrine syndrome (APS) type II. We reviewed previously published pediatric cases of anti-GAD65 autoimmune encephalitis to discuss their clinical features, laboratory tests, imaging findings, EEG patterns, and prognosis. Case presentation: An 8-year-old, male child presented to the outpatient department after experiencing generalized convulsions for twenty days. The child was admitted for epilepsy and had received oral sodium valproate (500 mg/day) in another center, where investigations such as USG abdomen and MRI brain revealed no abnormalities, however, had abnormal EEG with diffuse mixed activity in the left anterior middle prefrontal temporal region. On the follow-up day, a repeat blood test showed a very low serum drug concentration of sodium valproate hence the dose was increased to 750 mg/day. Then, the child experienced adverse effects including increased sleep, thirst, and poor appetite, prompting the parents to discontinue the medication. A repeat MRI showed increased signals on FLAIR sequences in the right hippocampus hence admitted for further management. The child's past history included a diagnosis of hypothyroidism at the age of 4, and receiving levothyroxine 75 mcg once daily. His parents are healthy with no history of any similar neurological, autoimmune, or genetic diseases, but his uncle had a history of epilepsy. At presentation, he had uncontrolled blood glucose levels with elevated HbA1c levels. Additionally, the serum and CSF autoantibodies were positive against the anti-GAD65 antibody with the titer of 1:100 and 1:32 respectively. The patient was managed with a mixed type of insulin regimen and received first-line immunotherapy (intravenous immunoglobulin, IVIG) for five consecutive days, followed by oral prednisone and sodium valproate as an antiepileptic drug. Upon achieving a favorable clinical outcome, the patient was discharged with oral medications. Results: Among the 15 pediatric patients reported in this literature, nine presented with limbic encephalitis (LE), three with extralimbic encephalitis (ELE), and three with a combination of limbic and extralimbic encephalitis. Most of these cases exhibited T2-W FLAIR hyperintensities primarily localized to the temporal lobes in the early phase, progressing to hippocampal sclerosis/atrophy in the later phase on MRI. EEG commonly showed slow or spike waves on frontotemporal lobes with epileptic discharges. Prognostic factors varied among patients, with some experiencing persistent refractory seizures, type-1 diabetes mellitus (T1DM), persistent memory impairment, persistent disability requiring full assistance, and, in severe cases, death. Conclusion: Our findings suggest that anti-GAD65 antibody-positive autoimmune encephalitis patients may concurrently present with other APS. Our unique case presented with multiple endocrine syndromes and represents the first reported occurrence in children. Early diagnosis and timely initiation of immunotherapy are crucial for improving clinical symptoms and reducing the likelihood of relapses or permanent disabilities. Therefore, emphasis should be placed on prompt diagnosis and appropriate treatment implementation to achieve better patient outcomes.

[Autoimmune polyendocrine syndrome in adults. Focus on rheumatological aspects of the problem: A review].

Autoimmune polyglandular syndromes (APS) are a heterogeneous group of clinical conditions characterized by functional impairment of multiple endocrine glands due to loss of central or peripheral immune tolerance. These syndromes are also often accompanied by autoimmune damage to non-endocrine organs. Taking into account the wide range of components and variants of the disease, APS is usually divided into a rare juvenile type (APS 1) and a more common adult type (APS 2-4). APS type 1 is caused by a monogenic mutation, while APS types 2-4 have a polygenic mode of inheritance. One subtype of adult APS (APS 3D) is characterized by a combination of autoimmune thyroid disease and autoimmune rheumatic disease. This review considers the available literature data on combinations that meet the above criteria. Many studies have noted a significantly higher prevalence of rheumatic diseases in patients with autoimmune thyroid disease compared with the control group. Also, as in a number of rheumatic diseases, a more frequent occurrence of autoimmune thyroiditis, primary hypothyroidism and Graves' disease was noted.

[Polyendocrine syndromes in dogs]. / Polyendokrine Syndrome beim Hund.

The autoimmune polyendocrine syndrome (APS) refers to a combination of autoimmune endocrine disorders. It is rarely described in dogs. The most common combinations are hypoadrenocorticism and hypothyroidism, followed by diabetes mellitus, and less often hypoparathyroidism and orchitis. The diagnosis of the APS is based on the diagnosis of each endocrinopathy, as is the therapy, which involves the substitution of deficient hormones. If a patient was previously stable under treatment and is showing further signs (e.g. polyuria, polydipsia, or weight loss), the development of additional endocrinopathies like hypoadrenocorticism or diabetes mellitus should be considered. The diagnosis of the initially diagnosed endocrinopathy should also be critically questioned. This article summarizes some cases of our own animal hospital and selected cases published in the available literature.

Clinical characteristics and management of autoimmune enteropathy in children: case reports and literature review.

BACKGROUND: Autoimmune enteropathy (AIE) defined by intractable diarrhoea and nonceliac enteropathy with villous atrophy, is a rare digestive disease. Case reports of this disease are sporadic and the clinical characteristics of AIE is seldom discussed. PURPOSE: We evaluate the clinical, laboratory, histopathological features, response to therapy and outcome of AIE in children. METHOD: We conducted a retrospective analysis of five children with AIE in our hospital. A comprehensive search of MEDLINE was performed using PubMed, through keywords of "autoimmune enteropathy, pediatric or children". The clinical manifestations, endoscopic results, pathological results, and medication therapy of these children were collected and the cases were divided into two groups, infants (≤ 1 year old) and children (> 1 year old). RESULTS: Five cases treated in our department: one case took eight years to make the final diagnosis; one case was positive for anti-intestinal epithelial cell (AE) antibody; three cases showed crypt apoptosis in histopathology; and two cases showed celiac-like changes. All cases were responsive to glucocorticoid therapy in the early stage of treatment, while three cases required immunosuppressant maintenance. After reviewing the literature, we performed a statistical analysis of 50 cases with a male-to-female ratio of 31:19. Among them, 35 patients (70%) were within 1 year of age, and their clinical manifestations were mainly watery stool (43 cases, 86%), weight loss (28 cases, 56%), abdominal distension (3 cases, 6%), serum AE or anti-goblet cell (AG) antibody positivity (32 cases, 64%), other immune-related antibodies (21 cases, 42%), gene mutations (9 cases, 18%), and family history (21 cases, 42%). All the children showed different degrees of intestinal villous atrophy. Thirty-seven (74%) of the children were treated early, and their clinical symptoms were relieved. Comparing the cases between different age groups, it was found that the mortality rate of children with onset in infancy was higher (P < 0.05), and there was no difference in other autoimmune diseases, AE antibody positivity rates, and other antibodies between the two groups. In addition to survival rate between different age group (P = 0. 005), there was no difference in sex, autoantibody positivity rate, single gene mutation, or family history between the two groups (P > 0.05) through analysis of mortality and clinical remission cases. CONCLUSION: Endoscopic examination and mucosal pathological examination should be performed to diagnose AIE in children with watery stool and weight loss who fail to be treated with diet therapy. Immunotherapy is the core of medical management of AIE and can improve prognosis. Children with a poor prognosis in infancy should be actively treated to reduce mortality rates associated with AIE.

Autoimmune polyglandular syndrome type 4: experience from a single reference center.

Purpose: To characterize patients with APS type 4 among those affected by APS diagnosed and monitored at our local Reference Center for Autoimmune Polyglandular Syndromes. Methods: Monocentric observational retrospective study enrolling patients affected by APS diagnosed and monitored in a Reference Center. Clinical records were retrieved and analyzed. Results: 111 subjects (51 males) were affected by APS type 4, mean age at the onset was 23.1 ± 15.1 years. In 15 patients the diagnosis of APS was performed during the first clinical evaluation, in the other 96 after a latency of 11 years (range 1-46). The most frequent diseases were type I diabetes mellitus and celiac disease, equally distributed among sexes. Conclusions: The prevalence of APS type 4 is 9:100,000 people. Type I diabetes mellitus was the leading indicator of APS type 4 in 78% subjects and in 9% permitted the diagnosis occurring as second manifestation of the syndrome. Our data, showing that 50% of patients developed APS type 4 within the first ten years, don't suggest any particular follow-up time and, more importantly, don't specify any particular disease. It is important to emphasize that 5% of women developed premature ovarian failure.

Leber congenital amaurosis as the initial and essential manifestation in a Chinese patient with autoimmune polyglandular syndrome Type 1.

PURPOSE: Autoimmune polyglandular syndrome Type 1 (APS-1) is a rare autosomal recessive disorder caused by defects in the autoimmune regulator (AIRE) gene. Patients are generally diagnosed at ages between five and fifteen years when they exhibit three or more manifestations, most typically mucocutaneous candidiasis, autoimmune Addison's disease, and hypoparathyroidism. Our study aims to report the first case of a Chinese APS-1 patient, presented with LCA as the initial and essential clinical feature of this rare syndrome. METHODS: Detailed medical and family history were recorded for the patient. Also, the comprehensive ophthalmological examinations were conducted. Whole exome sequencing (WES) was applied to screen pathogenic variants. Sanger sequencing validation and segregation analysis were further performed for confirmation. RESULTS: A 3-year-old boy with severely impaired vision and initially referred as LCA. However, with a detailed history review, oral candidiasis, dental enamel hypoplasia, and nail candida infection were revealed. Moreover, genetic analysis revealed the homozygous c.769C>T (p.R257X) in AIRE gene (NM_000383.3) as the causative variant. CONCLUSION: We presented one case diagnosed with APS-1 based on clinical characteristics and genetic analysis. Our study demonstrated that LCA could serve as a warning sign for APS-1 and a potential trigger of early screening, which might prevent life-threatening complications.

Ocular features of autoimmune polyendocrinopathy candidiasis ectodermal dystrophy.

Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a multisystemic rare genetic disorder characterised by abnormalities of the immune system. We report the ocular features of APECED in two siblings of an Indian family, out of four who are still living. The ocular features of this disorder primarily included madarosis, refractive error, heterochromia, corneal opacity and peripheral retinal pigment epithelium degeneration. There is marked phenotypical heterogeneity in this disorder. We found differences even between monozygotic twins. While one of the twins did not have any ocular issues, the other one did. The child with corneal involvement was the most symptomatic; however, it did not lead to visual impairment. On genetic workup, homozygous p.M1V mutation was found in exon 1 of AIRE gene that has not been studied in Indian subjects with APECED. To the best of our knowledge, there is no report in literature describing ocular features of APECED in an Indian family with distinctive genetic involvement.

Autoimmune adrenal insufficiency in children: a hint for polyglandular syndrome type 2?

BACKGROUND: Primary adrenal insufficiency (PAI) in childhood is a life-threatening disease most commonly due to impaired steroidogenesis. Differently from adulthood, autoimmune adrenalitis is a rare condition amongst PAI's main aetiologies and could present as an isolated disorder or as a component of polyglandular syndromes, particularly type 2. As a matter of fact, autoimmune polyglandular syndrome (APS) type 2 consists of the association between autoimmune Addison's disease, type 1 diabetes mellitus and/or Hashimoto's disease. CASE PRESENTATION: We report the case of an 8-year-old girl who presented Addison's disease and autoimmune thyroiditis at an early stage of life. The initial course of the disease was characterized by numerous crises of adrenal insufficiency, subsequently the treatment was adjusted in a tertiary hospital with improvement of disease control. CONCLUSIONS: APS type 2 is a rare condition during childhood, probably because it may remain latent for long periods before resulting in the overt disease. We recommend an early detection of APS type 2 and an adequate treatment of adrenal insufficiency in a tertiary hospital. Moreover, we underline the importance of a regular follow-up in patients with autoimmune diseases, since unrevealed and incomplete forms are frequent, especially in childhood.

Analysis of a series of Italian APECED patients with autoimmune hepatitis and gastro-enteropathies.

Introduction: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) syndrome is a rare monogenic disease determined by biallelic mutations in AIRE gene, which encodes a transcription factor essential for central immune tolerance. Classic diagnosis is determined by the presence of two of the main APECED clinical diseases: chronic mucocutaneous candidiasis, chronic hypoparathyroidism, and Addison's disease. Non-endocrine autoimmunity, involving the liver, intestine, eyes, and kidneys, is generally reported in a minority of European patients, while American APECED patients have a higher tendency of developing organ-specific non-endocrine manifestations early in life. This observation led to the revision of the diagnostic criteria to permit earlier diagnosis based on the appearance of one classic triad symptom or one non-classical manifestation at a young age in the presence of IFNωAbs or AIRE mutations (Ferre-Lionakis criteria). Patients and methods: We analyzed the clinical, genetic, and autoantibody (Ab) profiles in a series of 14 pediatric Italian APECED patients with gastrointestinal manifestations (seven male and seven female patients). Ten patients presented hepatitis (APECED-associated hepatitis (APAH)), while seven were affected by constipation, diarrhea, and malabsorption. Four patients had developed APAH before classic triad symptoms. Results: Based on the age of appearance of non-endocrine manifestations including APAH and gastro-enteropathy, the Ferre-Lionakis criteria would have allowed an expedited diagnosis in 11/14 patients. Abs to tryptophan hydroxylase (TPHAb) and hepatic aromatic l-amino acid decarboxylase (AADC) were significantly associated with APECED patients of the present series. Abs to cP4501A2 were detectable in the serum of 4/8 patients with APAH, and Abs to cP4502A6 were detectable in 3/8 patients. AADC Abs tested positive in 5/7 patients, which is indicative of gastrointestinal dysfunction in APECED and TPHAb in 5/7 patients with gastrointestinal dysfunction. IFNAb was significantly associated with the syndrome. Conclusion: Although Ferre-Lionakis expanded criteria applied to the American cohorts of APECED patients would require validation in independent large cohorts of European patients, the results of this study emphasize the importance to evaluate the presence and the age of appearance of APAH and autoimmune enteropathy even in European cohorts for an earlier APECED diagnosis. An earlier APECED diagnosis would also allow the prevention of episodes of life-threatening hypocalcemic seizures and adrenal crisis, which are the main manifestations of undiagnosed APECED.

A Rare Case of Autoimmune Enteropathy Associated with Autoimmune Hepatitis.

A 74-year-old woman was admitted for weight loss, abdominal pain and diarrhea for a year. Blood tests showed elevated transaminases, cholestasis and hyperbilirubinemia. Capsule endoscopy revealed extensively scattered lymphangiectasias, shortened villi and erosions in the jejunum and ileum. The histological examination of the small bowel mucosa biopsies evidenced severe mucosal atrophy and crypt hyperplasia, without significant intraepithelial lymphocytosis. The clinical picture, lack of response to a gluten-free diet and endoscopic and histopathologic findings were compatible with autoimmune enteropathy. Simultaneously, autoimmune hepatitis was also diagnosed. The patient showed significant improvement after starting treatment with prednisolone and azathioprine. To our knowledge, this is the first case of autoimmune enteropathy diagnosed simultaneously with autoimmune hepatitis.

SARS-CoV-2-induced adrenal crisis in a patient with autoimmune polyglandular syndrome type 1: case report.

Autoimmune polyglandular syndromes (APS) are rare disorders characterized by the coexistence of endocrine and non-endocrine dysfunctions mediated by autoimmune mechanisms. Autoimmune polyglandular syndrome type 1 is defined as coexistence of chronic mucocutaneous candidiasis, hypoparathyroidism, and autoimmune adrenal insufficiency. Addison's disease as the obligatory component is potentially life threatening.Herein, we demonstrate a case of a 44-year-old woman with APS-1 (hypoparathyroidism, adrenal insufficiency, hypergonadotropic hypogonadism) and SARS-CoV-2-induced adrenal crisis. The patient presented with the typical manifestations of hypotensive shock, electrolyte disturbances of hyponatremia and hyperkalemia, and hypoglycaemia.Our case report illustrates the increased risk of severe course of COVID-19 in APS-1 syndrome patients along with heightened exposure to medical complications. The case reinforced the significance of a timely diagnosis, appropriate treatment, and education of patients with such a rare condition like APS-1.

[Autoimmune polyglandular syndrome type 3 diagnosed with cerebral venous sinus thrombosis: a case report].

A 67-year-old woman with a history of diabetes mellitus was admitted to our hospital with convulsions due to bilateral frontal subcortical hemorrhages. MR venography showed a defect in the superior sagittal sinus, and thrombi were demonstrated in the same lesion with head MRI three-dimensional turbo spin echo T1-weighted imaging. She was diagnosed with cerebral venous sinus thrombosis. As precipitating factors, we found high levels of free T3 and T4, low levels of thyroid stimulating hormone, anti-thyroid stimulating hormone receptor antibody, and anti-glutamic acid decarboxylase antibody with her. We diagnosed her with autoimmune polyglandular syndrome type 3 with Graves' disease and slowly progressive type 1 diabetes mellitus. Since she also had nonvalvular atrial fibrillation, she was treated with apixaban subsequently to intravenous unfractionated heparin in the acute phase, resulting in partial regression of the thrombi. Autoimmune polyglandular syndrome should be considered when multiple endocrine disorders are identified as precipitating factors for cerebral venous sinus thrombosis.
