Does fludrocortisone treatment cause hypomagnesemia in children with primary adrenal insufficiency?

Background/aim: Aldosterone is a mineralocorticoid that secreted from adrenal glands and a known factor to increase magnesium excretion by direct and indirect effects on renal tubular cells. Although the frequency of hypomagnesemia was found to be approximately 5% in adult studies, there is no study in the literature investigating the frequency of hypomagnesemia in children by using fludrocortisone, which has a mineralocorticoid activity. Materials and methods: A multi-center retrospective study was conducted, including children who were under fludrocortisone treatment for primary adrenal insufficiency and applied to participant pediatric endocrinology outpatient clinics. Results: Forty-three patients (58.1% male, 41.9% prepubertal) included in the study, whose median age was 9.18 (0.61-19) years, and the most common diagnosis among the patients was a salt-wasting form of congenital adrenal hyperplasia (67.4%). Mean serum magnesium level was 2.05 (±0.13) mg/dL, and hypomagnesemia was not observed in any of the patients treated with fludrocortisone. None of the patients had increased urinary excretion of magnesium. Conclusion: Unlike the studies performed in adults, we could not find any evidence of magnesium wasting effect of fludrocortisone treatment with normal or even high doses in children and adolescents.

Stress-Dosed Glucocorticoids and Mineralocorticoids Before Intensive Endurance Exercise in Primary Adrenal Insufficiency.

Patients with primary adrenal insufficiency (PAI) require increased doses of glucocorticoids and mineralocorticoids during stressors, such as surgery, trauma, and sepsis. Although current guidelines exist for dose adjustments in these situations, there is no accepted dosing regimen for patients with PAI participating in intensive endurance exercise. Given the extensive physiologic stress of events, such as marathons, triathlons, and similar events, it is likely that a "stress-dose" of adrenal replacement therapy will not only prevent adrenal crisis, but also improve performance. A 50-year-old male endurance athlete with known PAI reported severe fatigue, nausea, and malaise after competing in prior marathons and intensive endurance exercise. After supplementing with glucocorticoids and mineralocorticoids before competition, he experienced decreased symptoms and improved performance. To better care for these patients, further studies should be conducted to provide safe and effective glucocorticoid and mineralocorticoid dose adjustments before intensive endurance exercise.

High-intensity interval training prevents oxidant-mediated diaphragm muscle weakness in hypertensive mice.

Hypertension is a key risk factor for heart failure, with the latter characterized by diaphragm muscle weakness that is mediated in part by increased oxidative stress. In the present study, we used a deoxycorticosterone acetate (DOCA)-salt mouse model to determine whether hypertension could independently induce diaphragm dysfunction and further investigated the effects of high-intensity interval training (HIIT). Sham-treated (n = 11), DOCA-salt-treated (n = 11), and DOCA-salt+HIIT-treated (n = 15) mice were studied over 4 wk. Diaphragm contractile function, protein expression, enzyme activity, and fiber cross-sectional area and type were subsequently determined. Elevated blood pressure confirmed hypertension in DOCA-salt mice independent of HIIT (P < 0.05). Diaphragm forces were impaired by ∼15-20% in DOCA-salt vs. sham-treated mice (P < 0.05), but this effect was prevented after HIIT. Myosin heavy chain (MyHC) protein expression tended to decrease (∼30%; P = 0.06) in DOCA-salt vs. sham- and DOCA-salt+HIIT mice, whereas oxidative stress increased (P < 0.05). Enzyme activity of NADPH oxidase was higher, but superoxide dismutase was lower, with MyHC oxidation elevated by ∼50%. HIIT further prevented direct oxidant-mediated diaphragm contractile dysfunction (P < 0.05) after a 30 min exposure to H2O-2 (1 mM). Our data suggest that hypertension induces diaphragm contractile dysfunction via an oxidant-mediated mechanism that is prevented by HIIT.-Bowen, T. S., Eisenkolb, S., Drobner, J., Fischer, T., Werner, S., Linke, A., Mangner, N., Schuler, G., Adams, V. High-intensity interval training prevents oxidant-mediated diaphragm muscle weakness in hypertensive mice.

Mineralocorticoid receptor stimulation effects on spatial memory in healthy young adults: A study using the virtual Morris Water Maze task.

OBJECTIVES: Stress hormones such as cortisol are known to influence a wide range of cognitive functions, including hippocampal based spatial memory. In the brain, cortisol acts via two different receptors: the glucocorticoid (GR) and the mineralocorticoid receptor (MR). As the MR has a high density in the hippocampus, we examined the effects of pharmacological MR stimulation on spatial memory. METHODS: Eighty healthy participants (40 women, 40 men, mean age=23.9years±SD=3.3) completed the virtual Morris Water Maze (vMWM) task to test spatial encoding and spatial memory retrieval after receiving 0.4mg fludrocortisone, a MR agonist, or placebo. RESULTS: There was no effect of MR stimulation on spatial encoding during the vMWM task. However, participants who received fludrocortisone exhibited improved spatial memory retrieval performance. There was neither a main effect of sex nor a sex-by-treatment interaction. CONCLUSION: In young healthy participants, MR stimulation improved hippocampal based spatial memory retrieval in a virtual Morris Water Maze task. Our study not only confirms the importance of MR function in spatial memory, but suggests beneficial effects of acute MR stimulation on spatial memory retrieval in humans.

Differential effects of mineralocorticoid and angiotensin II on incentive and mesolimbic activity.

The controls of thirst and sodium appetite are mediated in part by the hormones aldosterone and angiotensin II (AngII). The present study examined the behavioral and neural mechanisms of altered effort-value in animals treated with systemic mineralocorticoids, intracerebroventricular AngII, or both. First, rats treated with mineralocorticoid and AngII were tested in the progressive ratio operant task. The willingness to work for sodium versus water depended on hormonal treatment. In particular, rats treated with both mineralocorticoid and AngII preferentially worked for access to sodium versus water compared with rats given only one of these hormones. Second, components of the mesolimbic dopamine pathway were examined for modulation by mineralocorticoids and AngII. Based on cFos immunohistochemistry, AngII treatment activated neurons in the ventral tegmental area and nucleus accumbens, with no enhancement by mineralocorticoid pretreatment. In contrast, Western blot analysis revealed that combined hormone treatment increased levels of phospho-tyrosine hydroxylase in the ventral tegmental area. Thus, mineralocorticoid and AngII treatments differentially engaged the mesolimbic pathway based on tyrosine hydroxylase levels versus cFos activation.

Successful treatment of a cat with primary hypoadrenocorticism and severe hyponatremia with desoxycorticosterone pivalate (DOCP).

A 6-year-old, castrated male Siamese cat was diagnosed with primary hypoadrenocorticism, confirmed by an adrenocorticotopic hormone (ACTH) stimulation test documenting both hypocortisolism and hypoaldosteronism. The cat was successfully treated using a combination of prednisolone and desoxycorticosterone pivalate (DOCP). This case demonstrates that DOCP can be used successfully as mineralocorticoid supplementation in cats with hypoadrenocorticism and may have a longer therapeutic duration than that in dogs.

Traitement réussi d'un chat atteint d'hypoadrénocorticisme primaire et d'hyponatrémie à l'aide de pivalate de désoxycorticostérone (DOCP). Un diagnostic d'hypoadrénocorticisme primaire a été posé pour un chat Siamois castré âgé de 6 ans et confirmé par un test de stimulation de l'hormone adrénocorticotope (ACTH) qui a documenté l'hypocortisolisme et l'hypoaldostéronisme. Le chat a été traité avec succès à l'aide d'une combinaison de prednisolone et de pivalate de désoxycorticostérone (DOCP). Ce cas démontre que le DOCP peut être utilisé avec succès en tant que supplément de minéralocorticoïdes chez les chats atteints d'hypoadrénocorticisme et peut présenter une durée thérapeutique plus longue que chez les chiens.(Traduit par Isabelle Vallières).

Molecular testing in congenital adrenal hyperplasia due to 21α-hydroxylase deficiency in the era of newborn screening.

Newborn screening (NBS) identifies the majority of classical [salt-wasting (SW) and simple-virilizing (SV)] cases of congenital adrenal hyperplasia (CAH) due to 21α-hydroxylase (21α-OHase) during the first days of life. Diagnosis of classical CAH is confirmed by follow-up serum 17-hydroxyprogesterone and/or the adrenocorticotropin stimulation test; however, neither test definitively distinguishes between the classical subtypes. After confirmation, all newborns are started on hydrocortisone (glucocorticoid) and fludrocortisone (mineralocorticoid) treatment. While initiating fludrocortisone treatment in classical CAH patients, independent of subtype and before SW signs or symptoms occur, prevents a life-threatening SW crisis, it may later complicate distinguishing between the classical subtypes. Genotype-phenotype correlations in 21α-OHase deficiency are excellent; however, molecular testing is not a regular part of the diagnostic workup. Molecular testing on 39 patients (25 identified by NBS) with an already established diagnosis of CAH identified 11 SW patients (8 identified by NBS) whose mutations suggested further biochemical and clinical reassessment of their subtype. Overall, SW accounted for 57.6% of our classical CAH patients, below the generally accepted figure that >75% of classical CAH are comprised of the SW form. In the era of NBS, molecular testing is a valuable supplemental tool identifying patients who may benefit from reassessment of their salt-retaining ability.

What is the best long-term management strategy for patients with primary adrenal insufficiency?

Primary adrenal insufficiency is treated with glucocorticoid and mineralocorticoid replacement therapy. Recent data revealed that health-related quality of life in adrenal insufficiency is impaired in many patients and that patients with adrenal insufficiency are also threatened by an increased mortality and morbidity. This may be caused by inadequate glucocortiocid therapy and adrenal crisis. Therefore, the optimization of hormone replacement therapy remains one of the most challenging tasks in endocrinology because it is largely based on clinical grounds because of the lack of objective assessment tools. This article provides answers to the important daily clinical questions, such as correct dose finding, dose adaptation in special situations, e g, pregnancy, improvement of quality of life and measures for protection from adrenal crisis. Other important aspects discussed are side effects of glucocortiocid replacement therapy and interactions with other drugs.

Management of Infants with Congenital Adrenal Hyperplasia.

Treatment of congenital adrenal hyperplasia (CAH) requires lifelong replacement of glucocorticoids with regular follow up to manage associated morbidities. The current review focuses on follow-up and management of infants diagnosed with classical CAH pertinent to Indian context. Early initiation of oral hydrocortisone in divided doses is recommended after diagnosis in newborn period, infancy and childhood. Fludrocortisone is recommended for all infants with classical CAH. All infants should be monitored as per protocol for disease and treatment related complications. The role of prenatal steroids to pregnant women with previous history of CAH affected infant for prevention of virilization of female fetus is controversial.

[Therapy of primary hypoadrenocorticism in dogs with low dose desoxycorticosterone pivalate]. / Therapie des primären Hypoadrenokortizismus beim Hund mit niedrig dosiertem Desoxycorticosteronpivalat.

OBJECTIVE: Since 2016 the only approved drug for the treatment of primary hypoadrenocorticism (Addisons disease) in dogs in Germany is desoxycorticosterone pivalate (DOCP), namely Zycortal®. The initial dose recommended by the manufacturer is 2.2 mg/kg. Our own experience and select publications raise the suspicion that a distinctly lower initial dose would be sufficient. Mainly cost reduction motivates for dose reduction and with it comes a higher owner motivation and compliance. It was the objective of our retrospective study to show that an initial dose of 1.5 mg/kg DOCP is sufficient for controlling canine hypoadrenocorticism. MATERIAL AND METHODS: Dogs with primary hypoadrenocorticism were included if the initial starting dose was 1.5 mg/kg DOCP subcutaneously. The first, second and the last known dose of DOCP were documented. Electrolyte concentrations at the time of diagnosis as well as 10-14 days after the first injection, on the day of the second injection as well as at the last known injection were recorded. A dog was considered medically well-regulated when clinically healthy, sodium and potassium concentrations within the reference ranges, and when the responsible veterinarian did not recommended a dose alteration. RESULTS: All 13 included dogs were clinically healthy after the first or second injection. One dog received 1.6 mg/kg DOCP as last documented dose, all other dogs received ≤ 1.5 mg/kg (median: 1.3, range: 0.4-1.6) DOCP. Eleven dogs were injected once monthly, 2 dogs received injections every 60 days. The dogs were followed at least 7 months (median: 20 months, range: 7-26 months). CONCLUSION AND CLINICAL RELEVANCE: We were able to show that a starting dose of 1.5 mg/kg DOCP (Zycortal®) is sufficient for controlling primary hypoadrenocorticism in dogs. Adjustments of the dose are needed in some dogs. Regular measurement of electrolyte concentrations 10 days after treatment initiation and at the monthly DOCP injection is required for a correct disease management with DOCP.

Plasma Renin Measurements are Unrelated to Mineralocorticoid Replacement Dose in Patients With Primary Adrenal Insufficiency.

CONTEXT: No consensus exists for optimization of mineralocorticoid therapy in patients with primary adrenal insufficiency. OBJECTIVE: To explore the relationship between mineralocorticoid (MC) replacement dose, plasma renin concentration (PRC), and clinically important variables to determine which are most helpful in guiding MC dose titration in primary adrenal insufficiency. DESIGN: Observational, retrospective, longitudinal analysis. PATIENTS: A total of 280 patients (with 984 clinical visits and plasma renin measurements) with primary adrenal insufficiency were recruited from local databases and the international congenital adrenal hyperplasia (CAH) registry (www.i-cah.org). Thirty-seven patients were excluded from the final analysis due to incomplete assessment. Data from 204 patients with salt-wasting CAH (149 adults and 55 children) and 39 adult patients with Addison disease (AD) were analysed. MAIN OUTCOME MEASURES: PRC, electrolytes, blood pressure (BP), and anthropometric parameters were used to predict their utility in optimizing MC replacement dose. RESULTS: PRC was low, normal, or high in 19%, 36%, and 44% of patients, respectively, with wide variability in MC dose and PRC. Univariate analysis demonstrated a direct positive relationship between MC dose and PRC in adults and children. There was no relationship between MC dose and BP in adults, while BP increased with increasing MC dose in children. Using multiple regression modeling, sodium was the only measurement that predicted PRC in adults. Longitudinally, the change in MC dose was able to predict potassium, but not BP or PRC. CONCLUSIONS: The relationship between MC dose and PRC is complex and this may reflect variability in sampling with respect to posture, timing of last MC dose, adherence, and concomitant medications. Our data suggest that MC titration should not primarily be based only on PRC normalization, but also on clinical parameters such as BP and electrolyte concentration.

Current Management and Outcome of Pregnancies in Women With Adrenal Insufficiency: Experience from a Multicenter Survey.

CONTEXT: Appropriate management of adrenal insufficiency (AI) in pregnancy can be challenging due to the rarity of the disease and lack of evidence-based recommendations to guide glucocorticoid and mineralocorticoid dosage adjustment. OBJECTIVE: Multicenter survey on current clinical approaches in managing AI during pregnancy. DESIGN: Retrospective anonymized data collection from 19 international centers from 2013 to 2019. SETTING AND PATIENTS: 128 pregnancies in 113 women with different causes of AI: Addison disease (44%), secondary AI (25%), congenital adrenal hyperplasia (25%), and acquired AI due to bilateral adrenalectomy (6%). RESULTS: Hydrocortisone (HC) was the most commonly used glucocorticoid in 83% (97/117) of pregnancies. Glucocorticoid dosage was increased at any time during pregnancy in 73/128 (57%) of cases. In these cases, the difference in the daily dose of HC equivalent between baseline and the third trimester was 8.6 ± 5.4 (range 1-30) mg. Fludrocortisone dosage was increased in fewer cases (7/54 during the first trimester, 9/64 during the second trimester, and 9/62 cases during the third trimester). Overall, an adrenal crisis was reported in 9/128 (7%) pregnancies. Cesarean section was the most frequent mode of delivery at 58% (69/118). Fetal complications were reported in 3/120 (3%) and minor maternal complications in 15/120 (13%) pregnancies without fatal outcomes. CONCLUSIONS: This survey confirms good maternal and fetal outcome in women with AI managed in specialized endocrine centers. An emphasis on careful endocrine follow-up and repeated patient education is likely to have reduced the risk of adrenal crisis and resulted in positive outcomes.

Untreated congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Congenital adrenal hyperplasia (CAH) is an inherited metabolic disease caused by the deficiency of one of the enzymes necessary for cortisol synthesis. With carefully supervised medical treatment, CAH patients have the capacity for normal puberty and fertility. We report on a 12.4-year-old female who, because of the early interruption of treatment, developed progressive virilization with reduced final height and altered psycho-social orientation to male. One of the reasons for interrupting replacement therapy in our case was the difficult social and economic status of the family, who lived for many years without basic medical care.

Evaluation of a low-dose desoxycorticosterone pivalate treatment protocol for long-term management of dogs with primary hypoadrenocorticism.

BACKGROUND: Lowering the dose of desoxycorticosterone pivalate (DOCP) for the treatment of dogs with primary hypoadrenocorticism (PH) decreases costs and could lead to increased owner motivation to treat their affected dogs. OBJECTIVE: To evaluate the efficacy of a low-dose DOCP treatment protocol in dogs with PH. ANIMALS: Prospective study, 17 client-owned dogs with naturally occurring PH (12 newly diagnosed, 5 previously treated with fludrocortisone acetate [FC]). METHODS: Dogs with newly diagnosed PH were started on 1.5 mg/kg DOCP SC; dogs previously treated with FC were started on 1.0-1.8 mg/kg DOCP SC. Reevaluations took place at regular intervals for a minimum of 3 months and included clinical examination and determination of serum sodium and potassium concentrations. The DOCP dosage was adjusted to obtain an injection interval of 28-30 days and to keep serum electrolyte concentrations within the reference interval. RESULTS: Median (range) follow-up was 16.2 months (4.5-32.3 months). The starting dosage was sufficient in all but 2 dogs and had to be significantly decreased after 2-3 months to a median dosage (range) of 1.1 mg/kg (0.7-1.8). Dogs 3 years of age or younger needed significantly higher dosages compared to older dogs. None of them, however, needed the 2.2 mg/kg DOCP dosage, recommended by the manufacturer. CONCLUSIONS AND CLINICAL IMPORTANCE: A starting dosage of 1.5 mg/kg DOCP is effective in controlling clinical signs and serum electrolyte concentrations in the majority of dogs with PH. An additional dose reduction often is needed to maintain an injection interval of 28-30 days. Young and growing animals seem to need higher dosages.

Sex-Specific Risk of Cardiovascular Disease in Autoimmune Addison Disease-A Population-Based Cohort Study.

CONTEXT: Little is known of cardiovascular disease (CVD) in autoimmune Addison disease (AAD). Inadequate glucocorticoid replacement might potentially increase CVD risk. OBJECTIVE: To examine CVD in AAD in subgroups of ischemic heart disease (IHD) and cerebrovascular disease (CeVD) and investigate the effects of glucocorticoid and mineralocorticoid dosing. DESIGN, SETTING, AND PATIENTS: In this cohort-control study, we used Swedish health registries from 1964 to 2013 to identify 1500 subjects with AAD and 13,758 matched controls. Incident CVD was analyzed from 2006 to 2013. Adjusted hazard ratios (aHRs) were calculated using Cox proportional hazard models. Glucocorticoid and mineralocorticoid doses were stratified to examine dose-related risks. RESULTS: During 8807 person-years (PY), 94 events of first CVD (10.7/1000 PY) in patients with AAD occurred compared with 563 events during 80,163 PY (7.0/1000 PY) in controls. IHD was significantly more common in women (aHR, 2.15; 95% CI, 1.49 to 3.10) but not men (aHR, 1.16; 95% CI, 0.75 to 1.78) with AAD compared with controls. No increase in CeVD risk was detected (aHR, 0.88; 95% CI, 0.56 to 1.37, women; aHR, 0.88; 95% CI 0.53 to 1.50, men). CVD was associated with greater glucocorticoid and mineralocorticoid replacement doses in women but not men. CONCLUSION: The risk of IHD but not CeVD is increased in AAD, especially in women. The risk of CVD independently correlated with greater glucocorticoid and mineralocorticoid replacement doses in women. Our data suggest that close monitoring and early treatment of risk factors for CVD, among women in particular, might be warranted.

Chronic treatment with the mineralocorticoid hormone aldosterone results in increased anxiety-like behavior.

Aldosterone is the last component of the renin-angiotensin-aldosterone system inducing its peripheral effects via mineralocorticoid receptors (MR). Brain MR bind preferentially glucocorticoids. So far, the role of MR in behavioral functions has been investigated almost exclusively in relation to glucocorticoids. Recently, aldosterone itself has been linked to affective disorders. The aim of this study was to test the hypothesis that chronic elevation of circulating levels of aldosterone leads to increased anxiety. We have investigated the effects of chronic aldosterone treatment on (1) anxiety-like behavior, and (2) basal and stress-induced levels of selected hormones. Forty male Wistar rats were subcutaneously implanted with osmotic minipumps and treated with aldosterone (2 microg/100 g/day) or vehicle for two weeks. Aldosterone concentrations in plasma showed a mild (approximately four-fold) increase at the end of two-week aldosterone treatment. This mild hyperaldosteronism resulted in a significant enhancement of anxiety as demonstrated by alterations in all indicators of anxiety-like behavior measured in the open field and elevated plus-maze tests, without significant changes in measures of general locomotor activity. Aldosterone treatment affected not only the spatiotemporal measures of anxiety, but also the ethological parameters related to exploration and risk assessment. Chronic treatment with aldosterone was associated with increased water intake and decreased plasma renin activity, but failed to modify basal or stress-induced activity of the hypothalamic-pituitary-adrenocortical axis. The results provide evidence on anxiogenic action of prolonged increase in circulating aldosterone concentrations. Thus, aldosterone may represent an important target for future antidepressant and anxiolytic drug development.

Patients with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency can achieve their target height: the Leipzig experience.

BACKGROUND: Despite treatment, the mean final height (FH) of patients with classic congenital adrenal hyperplasia (CAH) is below the mean height of a normal population. AIMS: To show that CAH patients can achieve their target height (TH), 39 adult subjects, whose therapy had started in infancy, were studied in a retrospective analysis. All height SDS were corrected so that they related to TH SDS. PATIENTS: Group 1: patients born before 1975 (n = 13) had received prednisolone, at doses equivalent to hydrocortisone 39.4 +/- 15.6 mg/m2 BSA daily, together with DOCA in the first 2 years of life. Group 2: patients born from 1975 to 1986 (n = 26) received at this age lower hydrocortisone doses (16.4 +/- 6.9 mg/m2 BSA daily, divided 8 hourly; p < 0.001) combined with fludrocortisone, had outpatient visits every 3 months and bone age (BA) estimation every 6 months. RESULTS: Patients of group 1 (FH SDS -1.2 +/- 1.0) had a poor outcome, whereas patients of group 2 (FH SDS 0.1 +/- 0.9; p = 0.01) achieved their TH. CONCLUSION: Combined corticoid administration adjusted quarterly to keep height, BMI, blood pressure and BA within normal limits resulted in FH close to TH in patients with classic CAH.

[Testicular adrenal rest tumors (TART) in adult men with classic congenital adrenal hyperplasia (CAH)]. / Testikuläre adrenale Resttumoren (TART) bei erwachsenen Männern mit klassischem adrenogenitalen Syndrom (AGS).

BACKGROUND: Information about treatment of adult male patients with congenital adrenal hyperplasia (CAH) and testicular adrenal rest tumors (TART) is scarce. Diagnostic and therapeutic guidelines do not exist. The aim of this review is to evaluate the current state of therapeutic options in adult male patients with CAH. METHODS: We performed an extensive search of the literature of the last 10 years by using PubMed/MEDLINE. RESULTS: The aims of treatment in adult male patients with CAH are prevention of adrenal crisis and TART, improvement of general well-being, good quality of life and sexual well-being, fertility, and prevention of side effects of gluco- and mineralocorticoid therapy. However, fertility is impaired in these patients and correlates with TART. The current therapeutic concepts are discussed. CONCLUSIONS: A future system of regular follow-up visits and standards in therapeutic concepts is needed to guarantee an improved fertility and lifelong good quality of life in adult male patients with CAH.

Three new Brazilian cases of 17α-hydroxylase deficiency: clinical, molecular, hormonal, and treatment features.

BACKGROUND: Deficiency of 17α-hydroxylase (17OHD) is a rare form of adrenal hyperplasia. Diagnosis is generally delayed, impairing appropriate treatment. CASE PRESENTATION: Here, we report the clinical, molecular, hormonal, and treatment data of three unrelated 17OHD patients, aged 14-16 years with hypergonadotrophic hypogonadism; uncontrolled hypertension; primary adrenal insufficiency; and high progesterone, low to normal potassium, and low dehydroepiandrosterone, androstenedione, and testosterone levels. Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) at baseline and after an adrenocorticotropic hormone test showed low cortisol and cortisone and high deoxycorticosterone (DOC) and corticosterone levels; both DOC/21-deoxycortisol and costicosterone/cortisol ratios were very high. Patient 2 had 46,XX karyotype and patients 1 and 3, had 46,XY. A molecular analysis showed that two of the patients were homozygous for p.W406R mutation and the other patient was compound heterozygous for p.W406R and p.P428L. Hypertension was controlled only after the administration of both prednisone and mineralocorticoid antagonist. CONCLUSIONS: Hypertension in young women must lead to diagnostic suspicion, even in the pre-pubertal period. The basal level of progesterone is an indicator of 17OHD. Mineral and glucocorticoid ratios obtained from LC-MS/MS can reinforce the diagnosis. Hypertension can be controlled using glucocorticoid replacement therapy and mineralocorticoid antagonist.

Bilateral Adrenalectomy in Congenital Adrenal Hyperplasia: A Systematic Review and Meta-Analysis.

CONTEXT: Management of congenital adrenal hyperplasia (CAH) involves suppression of the hypothalamic-pituitary-adrenal axis using supraphysiological doses of exogenous glucocorticoids. This can pose a challenge, with Cushing syndrome a frequent complication of adequate suppression. Bilateral adrenalectomy, with subsequent replacement of glucocorticoids and mineralocorticoids at physiological doses, has been proposed as an alternative therapeutic strategy. OBJECTIVE: To review the outcomes after bilateral adrenalectomy for CAH. DATA SOURCES: A systematic search of PubMed/MEDLINE and Web of Science, identifying relevant reports published up to 10 January 2018. STUDY SELECTION: Case reports or case series were included if they reported individual patient data from patients with CAH who had undergone bilateral adrenalectomy. DATA EXTRACTION: Information regarding the following was extracted: first author, country, sex, age at adrenalectomy, year of adrenalectomy, diagnosis, molecular abnormality, pre- and postoperative biochemistry, pre- and postoperative medications, pre- and postoperative body mass index, indication for adrenalectomy, surgical technique, gross and microscopic adrenal characteristics, follow-up duration, and short- and long-term postoperative outcomes. DATA SYNTHESIS: We identified 48 cases of bilateral adrenalectomy for CAH, with patients aged from 4 months to 56 years at surgery. The most common indication for surgery was the inability to control hyperandrogenism/virilization and/or Cushing syndrome (n = 30; 62%). Most patients (n = 34; 71%) reported symptomatic improvement postoperatively, with some cases of short-term (n = 5; 10%) and long-term (n = 13; 27%) adverse outcomes. CONCLUSIONS: Bilateral adrenalectomy for CAH appears to be a reasonable therapeutic option for carefully selected patients who have had unsatisfactory outcomes with conventional medical management.
