21-hydroxylase (21-OH) is the main antigen of the adrenal cortex, so the determination of antibodies (Ab) to 21-OH can help in the diagnosis and prognosis of chronic primary adrenal insufficiency (CPAI). Purpose of the study: evaluation of the relevance of Ab to 21-OH for the diagnosis and prediction of autoimmune CPAI. Materials and methods of research: the study consisted of three blocks: 1) assessment of the specificity and sensitivity, as well as the prognostic potential of Ab to 21-OH in patients with polyglandular autoimmune syndrome (APS) – individuals with APS type 1 with and without CPAI (n=106); 2) assessment of the dynamics of the level of Ab to 21-OH – patients with autoimmune CPAI were included (n=41); 3) assessment of the significance of Ab data for the differential diagnosis of various forms of CPAI, including patients with CPAI and APS type 1 exclusion (n=30). The study of Ab to 21-hydroxylase was performed using enzymelinked immunosorbent assay (BioVendor kits, Czech Republic). Results: statistically significant differences were obtained in the frequency of detection of Ab to 21-OH in patients with or without PCNI (p<0,001). The sensitivity of the method was 96%, specificity was 75%, a positive predictive value was 90%, and the negative predictive value was 89%. In 83% of patients, the level of Ab decreased with time (median size decreases – 20,4%/year). An inverse relationship was also found between the level of Ab and the duration of the course of CPAI (R=–0,460, p<0,001). In a group of 30 patients with CPAI and with exclusion of APS type 1, 21 were found to have Ab to 21-OH, only one of them had a monogenic non-autoimmune cause of CPAI (a mutation in the MC2R gene). Monogenic forms of CPAI were found in another 7 patients (mutations were found in the DAX1 and ABCD1 genes), among them an increase in Ab to 21-OH was not detected. Conclusion: determination of Ab to 21-OH is a specific and sensitive method for the diagnosis of autoimmune CPAI. An increase in Ab to 21-OH is a risk marker of autoimmune CPAI development.

The article describes a clinical case of primary adrenal insufficiency which manifested at an atypically advanced age. Primary adrenal insufficiency combined with other clinical symptoms suggested the autoimmune polyendocrine syndrome type 1. Subsequently, the diagnosis was confirmed by the results of genetic testing. The particulars of the clinical case include the age of patient at manifestation of the disease (49  years). The lack of treatment resulted in dramatic clinical decompensation. This clinical case is intended to draw clinicians' attention to the necessity of detection of primary adrenal insufficiency and appropriate and timely treatment. Taking into account eventual diagnostic problems, it is necessary to raise awareness about this disease among practicing doctors of various specialties.

Abstract Objectives To describe an atypical presentation of primary adrenal insufficiency in conjunction with new onset type 1 diabetes. Case presentation Here, we describe a case of new-onset type 1 diabetes (T1D) presenting simultaneously with an unusual presentation of primary adrenal insufficiency in a previously healthy 16-year-old. He was admitted for a typical presentation of diabetic ketoacidosis, but with extreme hyponatremia. An extensive workup revealed a low aldosterone level, appropriate cortisol level, and positive 21-hydroxylase antibodies. While the phenomenon of multiple autoimmune conditions developing in the same patient is well-described, this particular case has several atypical aspects. Our patient’s case highlights the danger of relying on random serum cortisol in the setting of acute illness to rule out adrenal insufficiency. Conclusions Adrenal insufficiency can present as isolated hypoaldosteronism without hypocortisolemia and can manifest as severe hyponatremia in the context of diabetic ketoacidosis. Workup for an unusual presentation of T1D should include a 21-hydroxylase antibody, as well as thyroid and celiac disease studies.

Specificity And Sensitivity

AbstractThe aim of this study is to evaluate temperature measurement methods in children. Body temperatures of 3 to 18 years old patients were measured with a tympanic infrared thermometer, a noncontact infrared skin thermometer and with a temporal artery thermometer. While the specificity of temporal artery and noncontact thermometers were good in determination of temperatures above 37.5°C, their sensitivities were low. Positive predictive value and negative predictive value for both thermometers were sufficient. Both specificity and sensitivity of both thermometers were determined to be good at temperature values above ≥ 38°C. It is thought that noncontact and temporal artery thermometers can be used for screening in pediatric emergency departments.

The One

Primary adrenal insufficiency is manifested by a deficiency of adrenal cortex hormones and can lead to a life-threatening condition. Early diagnosis is key to patient survival. Auto-antibodies to one of the adrenal steroidogenesis enzymes, 21-hydroxylase, are an immunological marker of autoimmune adrenal insufficiency. On the one hand, the study of antibodies to 21-hydroxylase is a method that helps establish the etiology of the disease the autoimmune genesis of adrenal gland damage. On the other hand, the determination of autoantibodies to 21-hydroxylase is the only prognostic factor of the risk of adrenal insufficiency, which makes it possible to prevent the development of acute adrenal crisis. The article provides a brief literature review on autoantibodies to 21-hydroxylase and the pathogenesis of autoimmune adrenal insufficiency, and a series of clinical cases that illustrates the significant role of autoantibodies to 21-hydroxylase in diagnosis of adrenal insufficiency.

At present, four main types of autoimmune polyglandular syndromes (APS) are distinguished. Type 1 APS is associated with candidiasis, primary hypoparathyroidism, and primary adrenal insufficiency developing in the childhood as a result of mutations in the AIRE gene. Type 2 APS involves primary adrenal insufficiency in combination with autoimmune thyroid diseases and/or type 1 diabetes mellitus. Type 3 APS is characterized by the combination of autoimmune thyroid diseases with other endocrine and non-endocrine autoimmune pathologies in the absence of adrenal cortical dysfunction and hypoparathyriodism. Type 4 APS is presented by the combinations of autoimmune diseases other than the aforementioned ones. The above syndromes usually manifest themselves at the age between 20 and 60 years; they are of the polygenic type and associated with the genetic markers, such as HLAII-complex haplotypes, CTLA-4, PTPN22, FOXP3 genes, etc. In addition, the latent forms of APS have been described that occur in the populations much more frequently than the manifest disorders. These latent diseases can exert strong influence on the compensation and risk of complications of the underlying pathology. Of great importance in this context is the timely identification of the groups of patients at risk of developing clinical forms of APS among the subjects presenting with a single endocrine pathology.

Endocrinology Clinic

A 46-year-old woman was referred to the endocrinology clinic for evaluation of progressive fatigue, dizziness and treatment-resistant hypothyroidism. Initial laboratory results revealed hypothyroidism, hyponatraemia and hyperkalaemia. Liothyronine sodium (Cytomel) was initiated, which exacerbated her fatigue and dizziness. Suspecting adrenal insufficiency, an 08:00 cortisol level was obtained and found to be low with failure to increase following cosyntropin stimulation test. Diagnosis of primary adrenal insufficiency was confirmed via CT abdomen and pelvis revealing diminutive adrenal glands and elevated 21-hydroxylase antibody. Treatment was initiated with hydrocortisone 10 mg every morning and 5 mg at 16:00/day, with plan for patient follow-up in 3 weeks to assess need for mineralocorticoid replacement. Polyglandular syndromes are rare and have a wide variety of presentation. Thus, we recommend screening patients with a single autoimmune disorder who do not respond to conventional therapy to prevent possible life-threatening adrenal crisis.
