NEW-ONSET PRIMARY ADRENAL INSUFFICIENCY AFTER COVID-19: CASE REPORT.

COVID-19 primarily affects the respiratory system. What comes after the disease is now a greater concern for the scientific world. It is remarkable for causing endocrine organ involvement, particularly in the adrenal glands. However, its effect on the adrenal gland has not been fully elucidated. A case of primary adrenal insufficiency after COVID-19. A 31-year-old female patient who presented with complaints of weakness, anorexia, nausea, recent onset of vomiting, dizziness, and low blood pressure for two months was admitted to the outpatient Department of Endocrinology and Metabolism. After discharge, the patient had routine follow-ups, and here we present the information on the first and seventh month after discharge. The patient was diagnosed with primary adrenal insufficiency with cortisol <0.054 µg/dL and adrenocorticotropic hormone >1200 pg/mL in the laboratory. In the non-contrast computed tomography taken in the adrenal protocol, the stem and leaves of both adrenal glands are significantly thinned and appear atrophic, the right adrenal gland is hardly distinguished. Hydrocortisone was started. All complaints were resolved within a week, except hyperpigmentation, which was resolved six months later after treatment. Our study support adrenal gland involvement due to COVID-19, further research is needed to obtain data on damage mechanisms.

The multiple faces of autoimmune Addison's disease in children.

Primary adrenal insufficiency (PAI) is a rare medical condition, characterized by a deficiency in adrenal hormones. Although rare, PAI is a life-threatening disease requiring prompt recognition and treatment. However, symptoms of PAI are often non-specific and diagnosis can be challenging, causing frequent diagnostic delays. In adults, autoimmunity is the most common cause of PAI in industrialized countries, whereas in children, the most frequent etiology is represented by congenital defects of steroidogenesis and, in particular, by congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. A few recent case series from different countries have reported that autoimmunity is the second most common etiology of PAI in the pediatric age group. However, data on autoimmune PAI in children are still scant and the exact epidemiology, clinical manifestations, and long-term outcomes of this condition have yet to be defined. The scope of this review is to summarize the current knowledge on the etiology, presentation, and treatment of autoimmune PAI in childhood and to increase physicians' awareness of the signs that should raise an early suspicion of this condition.

Increased prevalence of negative pregnancy and fetal outcomes in women with primary adrenal insufficiency. A systematic review and meta-analysis.

Maternal primary adrenal insufficiency (PAI) during pregnancy, due to either Addison disease (AD) or congenital adrenal hyperplasia (CAH), is rare. Only few studies have examined the subsequent important outcomes of maternal glucocorticoid and mineralocorticoid deficiencies during pregnancy upon the fetus and the neonate. Therefore, this systematic review and meta-analysis evaluated the impact of these deficiencies, with data from PubMed/Medline, Cochrane/CENTRAL, and Google Scholar. A total of 31 studies were included for qualitative analysis and 11 for quantitative analysis. Studies examining the prevalence of spontaneous abortion, preterm birth, the occurrence of small for gestational age (SGA) neonates, as well as the neonatal birth weight were included. The systematic review revealed a substantial number of spontaneous abortions, preterm births and SGA neonates in pregnant women with PAI. The meta-analysis showed a mean spontaneous abortion prevalence of 18%, 18% and 17% in women with PAI, AD or CAH, respectively. The mean preterm birth prevalence was 11% when women with AD or CAH were analyzed together, and 13% and 9% in women with AD or CAH, respectively, when these women were analyzed separately. The mean prevalence of SGA neonates was 8% when women with AD or CAH were analyzed together, and 5% and 10% in women with AD or CAH, respectively, when these women were analyzed separately. The mean fetal birth weight was within normalcy in all women with PAI, as well as in women with AD or CAH. In conclusion the executed systematic review of 31 studies followed by a meta-analysis of 11 studies in pregnant women with PAI has shown a greater prevalence of pregnancies with negative outcome (spontaneous abortion, preterm birth) and of negative fetal outcome (SGA) in women with either AD or CAH, as compared to control pregnant women.

Insight into the role of TXNRD2 in steroidogenesis through a novel homozygous TXNRD2 splice variant.

OBJECTIVE: Adrenal cortisol production occurs through a biosynthetic pathway which depend on NADH and NADPH for energy supply. The mitochondrial respiratory chain and the reactive oxygen species (ROS) detoxification system are therefore important for steroidogenesis. Mitochondrial dysfunction leading to oxidative stress has been implicated in the pathogenesis of several adrenal conditions. Nonetheless, only very few patients with variants in one gene of the ROS detoxification system, Thioredoxin Reductase 2 (TXNRD2), have been described with variable phenotypes. DESIGN: Clinical, genetic, structural, and functional characterization of a novel, biallelic TXNRD2 splice variant. METHODS: On human biomaterial, we performed whole exome sequencing to identify and RNA analysis to characterize the specific TXNRD2 splice variant. Amino acid conservation analysis and protein structure modeling were performed in silico. Using patient's fibroblast-derived human induced pluripotent stem cells, we generated adrenal-like cells (iALC) to study the impact of wild-type (WT) and mutant TXNRD2 on adrenal steroidogenesis and ROS production. RESULTS: The patient had a complex phenotype of primary adrenal insufficiency (PAI), combined with genital, ophthalmological, and neurological features. He carried a homozygous splice variant c.1348-1G > T in TXNRD2 which leads to a shorter protein lacking the C-terminus and thereby affecting homodimerization and flavin adenine dinucleotide binding. Patient-derived iALC showed a loss of cortisol production with overall diminished adrenal steroidogenesis, while ROS production was significantly increased. CONCLUSION: Lack of TXNRD2 activity for mitochondrial ROS detoxification affects adrenal steroidogenesis and predominantly cortisol production.

Too Dry for Primary Adrenal Insufficiency (PAI): PAI Masked by Volume Depletion.

Adrenal insufficiency (AI) is a rare but potentially life-threatening endocrine disorder characterized by inadequate production or impaired response to adrenal hormones. Symptoms may range from acute emergent crisis presenting as hemodynamic shock or may be more chronic in presentation with a gradual onset of nonspecific symptoms. These vague symptoms are often accompanied by typical laboratory findings, such as hyponatremia, hypotension, and hyperkalemia, and point toward a diagnosis of chronic AI. In this case presentation, we demonstrate chronic AI presenting with severe hyponatremia, which was revealed after return to an euvolemic baseline. Because of an insidious presentation, AI can be both an incidental finding and easily missed. This case highlights the importance of evaluating suspected cases of AI at a baseline metabolic and hemodynamic state, including volume status. High clinical suspicion is warranted in these patients to avoid potential emergent adrenal crisis and to provide appropriate replacement therapy once etiology is established.

Clinical spectrum of human STAR variants and their genotype-phenotype correlation.

Biallelic variants of steroidogenic acute regulatory protein (STAR/STARD1) may cause primary adrenal insufficiency and 46,XY disorder of sex development. STAR plays a pivotal role in transporting cholesterol into mitochondria where cholesterol serves as an essential substrate for initiating steroid biosynthesis by its conversion to pregnenolone. Generally, loss-of-function mutations of STAR cause the classic form of lipoid congenital adrenal hyperplasia (LCAH) where steroidogenesis of the adrenal cortex and the gonads is severely affected. By contrast, partial activity of STAR causes a less severe phenotype, the non-classic LCAH, which is characterized by later onset and initial manifestation with isolated adrenal insufficiency only. Disease-causing STAR variants are very rare. Numerous variants of all types have been described worldwide. Prevailing variants have been reported from Japan and Korea and in some population clusters where STAR is more common. Genotype-phenotype correlation is pretty good for STAR variants. While the exact mechanisms of cholesterol transport into mitochondria for steroidogenesis are still under investigation, the important role of STAR in this process is evident by inactivating STAR variants causing LCAH. The mechanism of disease with STAR deficiency is best described by a two-hit model: the first hit relates to impaired cholesterol import into mitochondria and thus lack of substrate for all steroid hormone biosynthesis; the second hit then relates to massive cytoplasmic lipid overload (evidenced by typically enlarged and fatty adrenal glands) leading to cell death and organ destruction. This review summarizes phenotype and genotype characteristics of human STAR variants found through the ClinVar database.

Primary adrenal insufficiency developed 22 years after the diagnosis of light and heavy chain deposition disease: a case report.

Monoclonal immunoglobulin deposition diseases (MIDDs), including light and heavy chain deposition disease (LHCDD), are rare and heterogeneous disorders associated with underlying B-cell clonal disorders. Adrenal involvement is a potential extrarenal manifestation of MIDDs; however, limited data are available regarding its prevalence and clinical presentation. Herein, the present report describes, for the first time, a case of primary adrenal insufficiency that developed twenty-two years after a diagnosis of LHCDD had been made. A 69 year-old woman with a 10 year history of hemodialysis suddenly became bedridden after falling down stairs in the absence of focal neurological deficits. Subsequently, she experienced appetite loss, nausea, vomiting, a fever of unknown origin, and unexplained hypotension. Several months later, primary adrenal insufficiency and normal pressure hydrocephalus were diagnosed and successfully managed. The long-term clinical prognosis of MIDDs has not been fully elucidated despite recent advances in the management of the disorders. This report may contribute to improving our understanding of the disease course.

Novel STAR Gene Variant of Congenital Lipoid Adrenal Hyperplasia With Testicular Adrenal Rests.

A mutation in the steroidogenic acute regulatory protein (STAR) gene, which encodes a protein that plays a crucial role in steroid hormone synthesis, causes a severe form of congenital adrenal hyperplasia (CAH) known as lipoid CAH (LCAH). LCAH presents with primary adrenal insufficiency (PAI) as well as atypical genitalia. Individuals with LCAH require adrenal steroid hormone supplements for survival. Masculinization in males with STAR deficiency varies from incomplete to normal virilization. Radiological examinations reveal enlarged and lipid-laden adrenals. A 10-year-old boy born of second-degree consanguinity presented with weight gain and hyperpigmentation for 1 year. He was diagnosed with PAI at age 7 months and treated with hydrocortisone and fludrocortisone. Dynamic adrenal gland testing revealed undetectable hormone reserves. Imaging detected hypoplastic adrenals and a small testis with testicular adrenal rests (TART). Genetic analysis indicated a novel homozygous pathogenic variant of STAR in exon 7, c.814C > G(pArg272Gly) associated with LCAH (OMIM No. 201710). Testing revealed that asymptomatic family members and relatives were heterozygotes for the variant. The patient was diagnosed with nonclassic LCAH with hypoplastic adrenals and TART. Adequate hormone supplementation resulted in TART regression. This genetic variation is reported for the first time.

A Case of Primary Adrenal Insufficiency Triggered by Cytomegalovirus Infection after Obinutuzumab plus Bendamustine Therapy for Follicular Lymphoma.

A 69-year-old man was diagnosed with follicular lymphoma (Grade 3A). Obinutuzumab combined with bendamustine (OB) therapy was initiated as salvage chemotherapy. Nausea, abdominal pain, and hyponatremia appeared after six courses of OB therapy; cytomegalovirus (CMV) enteritis with primary adrenal insufficiency (PAI) was a complication. Ganciclovir and hydrocortisone were administered, and the clinical findings improved. PAI caused by CMV infection has mainly been reported in patients with acquired immunodeficiency syndrome. In the present case, the PAI triggered by CMV infection led to immunodeficiency after chemotherapy.

Severe adrenal insufficiency in six neonates with normal newborn screening for CAH.

BACKGROUND: Newborn screening (NBS) reduces the risk of mortality in congenital adrenal hyperplasia (CAH), mainly due to the salt-wasting form of 21-hydroxylase deficiency. There is limited knowledge regarding the results of NBS in non-CAH primary adrenal insufficiency (non-CAH PAI). PATIENTS AND METHODS: Clinical and NBS for CAH data of neonates who were diagnosed with non-CAH PAI between January and December 2022 were examined. RESULTS: Patients (n = 6, 4 females) were presented with severe hyperpigmentation (n = 6), hypoglycemia (n = 4), hyponatremia (n = 3), hyperkalemia (n = 1), respiratory distress syndrome (n = 1) between 3rd hour to 2 months of life. All had normal NBS results. The median first-tier 17-hydroxyprogesterone (17OHP) concentration in NBS for CAH was 0.14 ng/mL (range; 0.05-0.85). Molecular studies revealed biallelic mutations in the MC2R (n = 4; 3 homozygous, 1 compound heterozygous), MRAP (n = 1) and STAR (n = 1) genes. Glucocorticoid with or without mineralocorticoid replacement was initiated once the diagnosis of non-CAH PAI was established. CONCLUSION: Neonates with non-CAH PAI have always normal NBS due to persistently low 17OHP, even when these newborn infants are severely symptomatic for adrenal insufficiency. Clinicians should be alert for signs of adrenal insufficiency in neonates, even if the patient has a 'normal' screening for CAH, so as not to delay diagnosis and treatment. This fact should be kept in mind particularly in countries where these conditions are more common than elsewhere.

Challenges and pitfalls in the management of endocrine toxicities from immune checkpoint inhibitors: a case presentation of synchronous thyrotoxicosis and primary adrenal insufficiency in a melanoma patient.

BACKGROUND: Immune checkpoint inhibitors have revolutionized the therapeutic approach to several solid tumors, becoming the standard of care for cancer treatment in different disease settings. Despite the fact that these agents are better tolerated than conventional chemotherapy, their use is associated with a specific toxicity profile, so-called immune-related adverse events (irAEs), that can involve several organs. Endocrine irAEs are among the most frequent toxicities (around 10 to 16%) and include hypophysitis, thyroid disorders, adrenalitis, and diabetes mellitus. Some of them may be life-threatening if not promptly recognized (such as diabetic ketoacidosis and acute adrenal crisis). CASE PRESENTATION: A 55-year-old woman with a personal history of euthyroid Hashimoto's thyroiditis was diagnosed with a metastatic melanoma, BRAF wild type. Under treatment with anti-PD-1 pembrolizumab, she developed thyrotoxicosis followed by hypothyroidism due to destructive thyroiditis and concurrent primary adrenal insufficiency due to adrenalitis. CONCLUSIONS: The simultaneous occurrence of adrenal and thyroid autoimmune diseases, resembling autoimmune polyendocrine syndrome type 2, may occur as a rare but serious side effect of ICI treatment. It often presents with abrupt onset and rapid evolution towards polyglandular insufficiency. Physicians should be aware of the potential association of two or more endocrine disorders and careful monitoring of endocrine function is needed during ICI therapy.

Addison's disease caused by adrenal tuberculosis may lead to misdiagnosis of major depressive disorder: A case report.

BACKGROUND: Addison's disease (AD) is a rare but potentially fatal disease in Western countries, which can easily be misdiagnosed at an early stage. Severe adrenal tuberculosis (TB) may lead to depression in patients. CASE SUMMARY: We report a case of primary adrenal insufficiency secondary to adrenal TB with TB in the lungs and skin in a 48-year-old woman. The patient was misdiagnosed with depression because of her depressed mood. She had hyperpigmentation of the skin, nails, mouth, and lips. The final diagnosis was adrenal TB that resulted in the insufficient secretion of adrenocortical hormone. Adrenocortical hormone test, skin biopsy, T cell spot test of TB, and adrenal computed tomography scan were used to confirm the diagnosis. The patient's condition improved after hormone replacement therapy and TB treatment. CONCLUSION: Given the current status of TB in high-burden countries, outpatient doctors should be aware of and pay attention to TB and understand the early symptoms of AD.

Posaconazole-induced primary adrenal insufficiency: A rare but real risk.

Primary adrenal insufficiency (PAI) consists in a lack of adrenal hormones, and particularly of cortisol and aldosterone. It typically presents with fatigue, weakness, loss of appetite, increased thirst and skin hyperpigmentation. While most cases stem from an autoimmune etiology, rare instances of PAI have been attributed to infection, adrenal hemorrhage and medication disrupting steroidogenesis pathways. This report presents two patients with hematologic malignancies who developed primary glucocorticoid deficiency due to posaconazole. Both received allogeneic stem-cell transplantation and used posaconazole as antifungal prophylaxis. Both patients had low morning cortisol and elevated ACTH levels, which suggested primary adrenal insufficiency. Posaconazole, widely used for antifungal prophylaxis and long-term therapy, undoubtedly affects adrenal steroid synthesis. Thus, healthcare providers must be aware of that posaconazole may cause adrenal insufficiency, and should monitor patients taking this medication.

Lack of NAD(P)+ transhydrogenase activity in patients with primary adrenal insufficiency due to NNT variants.

BACKGROUND: Pathogenic variants in the nicotinamide nucleotide transhydrogenase gene (NNT) are a rare cause of primary adrenal insufficiency (PAI), as well as functional impairment of the gonads. OBJECTIVE: Despite the description of different homozygous and compound heterozygous NNT variants in PAI patients, the extent to which the function and expression of the mature protein are compromised remains to be clarified. DESIGN: The activity and expression of mitochondrial NAD(P)+ transhydrogenase (NNT) were analyzed in blood samples obtained from patients diagnosed with PAI due to genetically confirmed variants of the NNT gene (n = 5), heterozygous carriers as their parents (n = 8), and healthy controls (n = 26). METHODS: NNT activity was assessed by a reverse reaction assay standardized for digitonin-permeabilized peripheral blood mononuclear cells (PBMCs). The enzymatic assay was validated in PBMC samples from a mouse model of NNT absence. Additionally, the PBMC samples were evaluated for NNT expression by western blotting and reverse transcription quantitative polymerase chain reaction and for mitochondrial oxygen consumption. RESULTS: NNT activity was undetectable (<4% of that of healthy controls) in PBMC samples from patients, independent of the pathogenic genetic variant. In patients' parents, NNT activity was approximately half that of the healthy controls. Mature NNT protein expression was lower in patients than in the control groups, while mRNA levels varied widely among genotypes. Moreover, pathogenic NNT variants did not impair mitochondrial bioenergetic function in PBMCs. CONCLUSIONS: The manifestation of PAI in NNT-mutated patients is associated with a complete lack of NNT activity. Evaluation of NNT activity can be useful to characterize disease-causing NNT variants.

[Case Report of a 14-Year-Old Girl with Addison's Disease Under Initial Presumptive Diagnosis of Anorexia Nervosa: Confusingly Similar and Yet so Different?] / Kasuistik einer früh im Lebensverlauf an Morbus Addison erkrankten 14 Jahre alten Patientin bei Verdachtsdiagnose einer Anorexia nervosa.

Case Report of a 14-Year-Old Girl with Addison's Disease Under Initial Presumptive Diagnosis of Anorexia Nervosa: Confusingly Similar and Yet so Different? Abstract: Objective: Primary adrenal insufficiency (Addison's disease) is a rare differential diagnosis of anorexia nervosa. This case report presents important differential diagnostic aspects. Methods: We prepared a case report of a 14-year-old female patient according to the CARE guidelines, taking the patient's and the child's parents' view into consideration. Results: The diagnosis of primary adrenocortical insufficiency was reached using specific laboratory diagnostics approximately 9 months after the onset of symptoms, including sudden body weight loss. Significant differential diagnostic aspects were the absence of a body schema disorder and skin hyperpigmentation prominent in the physical examination. The patient experienced a high psychosocial burden because of the unclear diagnosis over 9 months. The diagnosis and substitution therapy with hydrocortisone led to a rapid improvement of the physical and psychological symptoms. Conclusions: This case report emphasizes the importance of a thorough somatic differential diagnosis in the context of a suspected anorexia nervosa.

Ultradian hydrocortisone replacement alters neuronal processing, emotional ambiguity, affect and fatigue in adrenal insufficiency: The PULSES trial.

BACKGROUND: Primary adrenal insufficiency (PAI) mortality and morbidity remain unacceptably high, possibly arising as glucocorticoid replacement does not replicate natural physiology. A pulsatile subcutaneous pump can closely replicate cortisol's circadian and ultradian rhythm. OBJECTIVES: To assess the effect of pump therapy on quality of life, mood, functional neuroimaging, behavioural/cognitive responses, sleep and metabolism. METHODS: A 6-week randomised, crossover, double-blinded and placebo-controlled feasibility study of usual dose hydrocortisone in PAI administered as either pulsed subcutaneous or standard care in Bristol, United Kingdom (ISRCTN67193733). Participants were stratified by adrenal insufficiency type. All participants who received study drugs are included in the analysis. The primary outcome, the facial expression recognition task (FERT), occurred at week 6. RESULTS: Between December 2014 and 2017, 22 participants were recruited - 20 completed both arms, and 21 were analysed. The pump was well-tolerated. No change was seen in the FERT primary outcome; however, there were subjective improvements in fatigue and mood. Additionally, functional magnetic resonance imaging revealed differential neural processing to emotional cues and visual stimulation. Region of interest analysis identified the left amygdala and insula, key glucocorticoid-sensitive regions involved in emotional ambiguity. FERT post hoc analysis confirmed this response. There were four serious adverse events (AE): three intercurrent illnesses requiring hospitalisation (1/3, 33.3% pump) and a planned procedure (1/1, 100% pump). There was a small number of expected AEs: infusion site bruising/itching (3/5, 60% pump), intercurrent illness requiring extra (3/7, 42% pump) and no extra (4/6, 66% pump) steroid. CONCLUSIONS: These findings support the administration of hormone therapy that mimics physiology.

A novel mutation in the NNT gene causing familial glucocorticoid deficiency, with a literature review.

Familial glucocorticoid deficiency (FGD) is an autosomal recessive disorder characterized by low cortisol levels despite elevated adrenocorticotropin (ACTH). Mineralocorticoid secretion is classically normal. Clinical manifestations are secondary to low cortisol levels (recurrent hypoglycemia, chronic asthenia, failure to thrive, seizures) and high levels of ACTH (cutaneous-mucosal hyperpigmentation). FGD is often caused by mutations in the ACTH melanocortin 2 receptor gene (MC2R, 18p11.21, FGD type 1) or melanocortin receptor 2 accessory protein gene (MRAP, 21q22.11, FGD type 2). But mutations have also been described in other genes: the steroidogenic acute regulatory protein (STAR, 8q11.2q13.2, FGD type 3), nicotinamide nucleotide transhydrogenase (NNT, 5p12, FGD type 4) and thioredoxin reductase 2 genes (TXNRD2, 22q11.21, FGD type 5). We report the case of a 3-year-old boy recently diagnosed with FGD type 4 due to a novel mutation in NNT gene. A homozygous variant in exon 18 of the NNT gene, NM_012343.3:c.2764C>T, p.(Arg922*), determines a stop codon and, consequently, a non-functional truncated protein or absence of protein due to the nonsense-mediated decay (NMD) mechanism. We review the recent literature on NNT mutations and clinical presentations, which are broader than suspected. This disorder can result in significant morbidity and is potentially fatal if untreated. Precise diagnosis allows correct treatment and follow-up.

Major immunophenotypic abnormalities in patients with primary adrenal insufficiency of different etiology.

Introduction: Patients with primary adrenal insufficiency (PAI) suffer from increased risk of infection, adrenal crises and have a higher mortality rate. Such dismal outcomes have been inferred to immune cell dysregulation because of unphysiological cortisol replacement. As the immune landscape of patients with different types of PAI has not been systematically explored, we set out to immunophenotype PAI patients with different causes of glucocorticoid (GC) deficiency. Methods: This cross-sectional single center study includes 28 patients with congenital adrenal hyperplasia (CAH), 27 after bilateral adrenalectomy due to Cushing's syndrome (BADx), 21 with Addison's disease (AD) and 52 healthy controls. All patients with PAI were on a stable GC replacement regimen with a median dose of 25 mg hydrocortisone per day. Peripheral blood mononuclear cells were isolated from heparinized blood samples. Immune cell subsets were analyzed using multicolor flow cytometry after four-hour stimulation with phorbol myristate acetate and ionomycin. Natural killer (NK-) cell cytotoxicity and clock gene expression were investigated. Results: The percentage of T helper cell subsets was downregulated in AD patients (Th1 p = 0.0024, Th2 p = 0.0157, Th17 p < 0.0001) compared to controls. Cytotoxic T cell subsets were reduced in AD (Tc1 p = 0.0075, Tc2 p = 0.0154) and CAH patients (Tc1 p = 0.0055, Tc2 p = 0.0012) compared to controls. NKCC was reduced in all subsets of PAI patients, with smallest changes in CAH. Degranulation marker CD107a expression was upregulated in BADx and AD, not in CAH patients compared to controls (BADx p < 0.0001; AD p = 0.0002). In contrast to NK cell activating receptors, NK cell inhibiting receptor CD94 was upregulated in BADx and AD, but not in CAH patients (p < 0.0001). Although modulation in clock gene expression could be confirmed in our patient subgroups, major interindividual-intergroup dissimilarities were not detected. Discussion: In patients with different etiologies of PAI, distinct differences in T and NK cell-phenotypes became apparent despite the use of same GC preparation and dose. Our results highlight unsuspected differences in immune cell composition and function in PAI patients of different causes and suggest disease-specific alterations that might necessitate disease-specific treatment.

Health-Related Quality of Life in Patients with Primary Adrenal Insufficiency.

(1) Background: Patients with primary adrenal insufficiency (PAI) suffer from a reduced quality of life. However, clinical factors associated with this impairment remain unclear. The aim of this study was to assess the health-related quality of life (HRQoL) and to evaluate the associations with clinical and hormonal parameters in a group of patients with PAI. (2) Methods: The study included 32 patients with autoimmune PAI, who answered the quality of life in Addison's disease questionnaire (AddiQoL). Clinical data and hormonal measurements were collected from the patients. (3) Results: The total AddiQoL score of males was significantly higher than that of females (p = 0.011). Furthermore, males reached significantly higher scores in each of the four subscales (fatigue-p = 0.013, emotional sphere-p = 0.048, adrenal insufficiency symptoms-p = 0.039, and miscellaneous questions-p = 0.034). There was a negative correlation between HRQoL and gonadotropin levels (FSH and fatigue r = (-)0.38, p = 0.032; FSH and emotional sphere r = (-)0.416, p = 0.018). This study found no significant associations between AddiQoL scores and the presence of autoimmune comorbidities; only fatigue scores were worse in the presence of autoimmune thyroiditis (p = 0.034). The doses of hydrocortisone and fludrocortisone in the replacement therapy were not associated with AddiQoL scores. AddiQoL scores correlated negatively with the age of diagnosis (p = 0.015). (4) Conclusions: Female sex, higher gonadotropins level, and older age at diagnosis were associated with impaired HRQoL in the studied group of patients with PAI.

Primary Adrenal Insufficiency in Acute Progressive Systemic Inflammation Accompanied by Latent Tuberculosis: A Case Report.

A 64-year-old man presented with general malaise, edema, and other nonspecific symptoms, prompting extensive diagnostic evaluation. The patient's early morning cortisol and adrenocorticotropic hormone levels were consistent with primary adrenal insufficiency without evident secondary or tertiary causes on magnetic resonance imaging. The interferon gamma release assay (T-SPOT®) was positive, suggesting latent tuberculosis, although there were no signs of active tuberculosis. The potential of extrapulmonary tuberculosis as a causative factor for adrenal insufficiency was explored but remained unconfirmed on contrast-enhanced computed tomography. Eosinophilia was detected, suggesting a link between adrenal insufficiency and the occurrence of atopic dermatitis. This case underscores the multifaceted nature of adrenal insufficiency and its potential associations. While autoimmune conditions are commonly associated with adrenal insufficiency, infectious diseases (e.g., tuberculosis) can also be contributing factors. Eosinophilia further indicates the likelihood of coexisting allergic or atopic conditions, particularly adrenal dysfunction. Although not dominant, the presence of latent tuberculosis can cause severe complications, including adrenal insufficiency, highlighting the requirement of vigilant monitoring. Clinicians are advised to consider adrenal insufficiency in the differential diagnosis of patients with generalized symptoms and perform comprehensive evaluations, including cortisol level assessment and tuberculosis screening.
