RESUMO

Introducción: la hiperplasia suprarrenal congénita (HSC) comprende un conjunto de enfermedades hereditarias que involucran alteraciones en el ciclo del cortisol a nivel enzimático. La forma clásica tiene una incidencia de 1:14.000 a 1:18.000 nacimientos, mientras que la no clásica se presenta en 1:2.000 recién nacidos. Según la enzima involucrada, las manifestaciones clínicas varían desde asintomáticas a alteraciones en medio interno que comprometen la vida, por lo que debe tenerse un alto nivel de sospecha clínica para diagnosticarla en forma oportuna. En Uruguay, desde el año 2007, se cuenta con el pesquisaje de la 17-OH progesterona, producto aumentado en la forma más frecuente de HSC. El diagnóstico prenatal mediante la búsqueda de mutaciones en el gen CYP21A2, a través de punción de vellosidades coriales o amniocentesis, o del ADN fetal en sangre materna se recomienda en HSC con ambos padres portadores de la mutación severa y el antecedente de un hijo previo con la forma clásica. El tratamiento prenatal se considera en etapa experimental, con dexametasona en fetos femeninos con riesgo de enfermedad clásica, manteniéndose con la confirmación hasta el parto. Se presenta el caso clínico de una recién nacida de 11 días con HSC perdedora de sal y virilización de genitales externos, diagnosticada por la pesquisa neonatal. Se reporta su manejo interdisciplinario y evolución. Conclusiones: la hiperplasia suprarrenal es una enfermedad hereditaria potencialmente grave. La pesquisa neonatal constituye una herramienta efectiva para la detección de esta enfermedad. El manejo multidisciplinario es clave para el seguimiento y la optimización del tratamiento.


Introduction: congenital adrenal hyperplasia (CAH) involves a set of hereditary diseases that include alterations in the cortisol cycle, at enzymatic level. The classic variant has an incidence of 1:14,000 to 1:18,000 births, while the non-classic one occurs in 1:2,000 newborns. As a result of the enzyme involved, the clinical manifestations change from asymptomatic to alterations in the internal environment that compromise life, so clinical suspicion must be high in order to diagnose it in a timely manner. The diagnosis is more frequently made by neonatal screening than by physical examination, and it is a more sensitive method, especially in males, since there are no changes at the level of external genitalia. The implementation of screening has reduced the time prior to diagnosis. In Uruguay, since 2007, a universal screening has been carried out measuring 17-OH progesterone, which is increased in the most frequent form of CAH. Treatment is lifelong, consisting of oral glucocorticoids (hydrocortisone) and mineralocorticoids (fludrocortisone). We recommend prenatal diagnosis by searching for mutations in the CYP21A2 gene through chorionic villus puncture or amniocentesis, or fetal DNA in maternal blood in cases of CAH if both parents are carriers of the severe mutation and have a history of a previous classic case. Prenatal treatment with dexamethasone is considered in the experimental stage, in female fetuses at risk of the standard disease, which is maintained until birth if confirmed. We present a clinical case of an 11-day-old newborn with salt-wasting congenital adrenal hyperplasia and virilization of the external genitalia, diagnosed by neonatal screening. We report her management and interdisciplinary evolution. Conclusion: adrenal hyperplasia is a potentially serious inherited disease. Neonatal screening is an effective tool for detecting this disease. Multidisciplinary management is key to monitoring and optimizing treatment.


Introdução: a hiperplasia adrenal congênita (HAC) compreende um conjunto de doenças hereditárias que envolvem alterações no ciclo do cortisol, em nível enzimático. A forma clássica tem incidência de 1:14.000 a 1:18.000 nascimentos, enquanto a forma não clássica ocorre em 1:2.000 recém-nascidos. Dependendo da enzima envolvida, as manifestações clínicas variam de assintomáticas até alterações do ambiente interno que comprometem a vida, portanto é necessário ter um alto nível de suspeita clínica para diagnosticá-la em forma precoce. No Uruguai, desde 2007, existe triagem para 17-OH progesterona, produto aumentado na forma mais frequente de HAC. O diagnóstico pré-natal pela busca de mutações no gene CYP21A2 por meio de punção de vilosidades coriônicas ou amniocentese, ou DNA fetal no sangue materno é recomendado na HAC com ambos os pais portadores da mutação grave e história de filho anterior com a forma clássica. O tratamento pré-natal é considerado em fase experimental, com dexametasona em fetos femininos com risco de doença clássica, continuando com confirmação até o parto. É apresentado o caso clínico de um recém-nascido de 11 dias com hiperplasia adrenal congênita perdedora de sal e virilização da genitália externa, diagnosticado por triagem neonatal. Relatamos sua gestão interdisciplinar e evolução. Conclusões: a hiperplasia adrenal é uma doença hereditária potencialmente grave. A triagem neonatal é uma ferramenta eficaz para detectar esta doença. O manejo multidisciplinar é fundamental para monitorar e otimizar o tratamento.

RESUMO

SUMMARY Hyperreninemic hypoaldosteronism due to aldosterone synthase (AS) deficiency is a rare condition typically presenting as salt-wasting syndrome in the neonatal period. A one-month-old Portuguese boy born to non-consanguineous parents was examined for feeding difficulties and poor weight gain. A laboratory workup revealed severe hyponatremia, hyperkaliaemia and high plasma renin with unappropriated normal plasma aldosterone levels, raising the suspicion of AS deficiency. Genetic analysis showed double homozygous of two different mutations in the CYP11B2 gene: p.Glu198Asp in exon 3 and p.Val386Ala in exon 7. The patient maintains regular follow-up visits in endocrinology clinics and has demonstrated a favourable clinical and laboratory response to mineralocorticoid therapy. To our knowledge, this is the first Portuguese case of AS deficiency reported with confirmed genetic analysis.

RESUMO

Intradialytic hypotension during dialysis adversely affects a patient's prognosis and increases mortality. We report a case in which intradialytic hypotension that persisted after the administration of midodrine was relieved after the use of fludrocortisone. Administration of 0.2 mg of fludrocortisone occurred 30 minutes before dialysis. We compared 45 sessions of dialysis without fludrocortisone administration and 45 sessions of dialysis with fludrocortisone administration in one patient. The number of times in which systolic blood pressure became lower than 80 mmHg and the number of early terminations of dialysis due to a decrease in systolic blood pressure were higher in the sessions without fludrocortisone administration than in the sessions with fludrocortisone administration (P < 0.05). Fludrocortisone may be helpful for the treatment of intradialytic hypotension that does not respond to midodrine administration.

RESUMO

BACKGROUND: Primary adrenal insufficiency (PAI) is a rare, potentially life-threatening condition. There are few Korean studies on PAI, and most have had small sample sizes. We aimed to examine the etiology, clinical characteristics, treatment, and mortality of PAI in Korean patients. METHODS: A nationwide, multicenter, registry-based survey was conducted to identify adults diagnosed with or treated for PAI at 30 secondary or tertiary care institutions in Korea between 2000 and 2014. RESULTS: A total of 269 patients with PAI were identified. The prevalence of PAI was 4.17 per million. The estimated incidence was 0.45 per million per year. The mean age at diagnosis was 49.0 years, and PAI was more prevalent in men. Adrenal tuberculosis was the most common cause of PAI in patients diagnosed before 2000; for those diagnosed thereafter, adrenal metastasis and tuberculosis were comparable leading causes. The etiology of PAI was not identified in 34.9% of cases. Of the patients receiving glucocorticoid replacement therapy, prednisolone was more frequently administered than hydrocortisone (69.4% vs. 26.5%, respectively), and only 27.1% of all patients received fludrocortisone. We observed an increased prevalence of metabolic disease and osteoporosis during the follow-up period (median, 60.2 months). The observed overall mortality and disease-specific mortality rates were 11.9% and 3.1%, respectively. CONCLUSION: The prevalence of PAI is significantly lower in Koreans than in reports from Western countries. The high frequency undetermined etiology in patients with PAI suggests the need to reveal accurate etiology of PAI in Korea.

RESUMO

Antley-Bixler syndrome (ABS) is a rare form of syndromic craniosynostosis with additional systemic synostosis, including radiohumeral or radioulnar synostosis. Another characteristic feature of ABS is mid-facial hypoplasia that leads to airway narrowing after birth. ABS is associated with mutations in the FGFR2 and POR genes. Patients with POR mutations present with either skeletal manifestations or congenital adrenal hyperplasia with ambiguous genitalia. We report here two cases of ABS caused by mutations in FGFR2 and POR. Although the patients had craniosynostosis and radiohumeral synostosis in common and cranioplasty was performed in both cases, the male with POR mutations showed an elevated level of 17α-hydroxyprogesterone during newborn screening and was diagnosed with congenital adrenal hyperplasia by adrenocorticotropic hormone stimulation. This patient has been treated with hydrocortisone and fludrocortisone. He had no ambiguous genitalia but had bilateral cryptorchidism. On the other hand, the female with the FGFR2 mutation showed severe clinical manifestations: upper airway narrowing leading to tracheostomy, kyphosis of the cervical spine, and coccyx deformity. ABS shows locus heterogeneity, and mutations in two different genes can cause similar craniofacial and skeletal phenotypes. Because the long-term outcomes and inheritance patterns of the disease differ markedly, depending on the causative mutation, early molecular genetic testing is helpful.

RESUMO

No Hospital de Base de São José do Rio Preto, uma paciente com diabetes melito tipo 2, apresentando quadro de acidose metabólica, foi tratada na emergência da clínica médica. Foi seguido inicialmente protocolo de cetoacidose diabética. Após um dia sem melhora clínica, com a hipótese diagnóstica de acidose tubular renal tipo IV, confirmada pela acidose metabólica hipercalêmica e hiperclorêmica, foi optado por introduzir fludrocortisona no tratamento. Devido à melhora clínica e laboratorial fechou-se o diagnóstico e a paciente encontra-se em acompanhamento no ambulatório.


At the Hospital de Base hospital in São José do Rio Preto, a type II diabetic patient presenting metabolic acidosis was treated at the internal medicine ER. Initially the diabetic ketoacidosis treatment protocol was followed. Due to no improvement after one day of treatment, the diagnostic hypothesis of renal tubular acidosis type IV was confirmed by the hyperkalemic and hyperchloremic metabolic acidosis. We treated the patient with fludrocortisone. Due to clinical recovery and improvement of laboratory results, the patient was discharged and is now an outpatient in our institution.

RESUMO

Hyponatremia secondary to the Syndrome of Inappropriate Anti-Diuretic Hormone [SIADH] secretion is commonly observed in patients with various neurological disorders. Cerebral Salt Wasting [CSW] resulting in hyponatremia is also an infrequent occurrence in some patients with neurological disorders. Confusion in differentiating CSW from SIADH may arise since both results in similar electrolyte disturbances. Herein, we report three cases of CSW with intracranial afflictions. CSW was diagnosed on the basis of fractional excretion of urinary sodium and uric acid along with extremely low serum uric acid. Improvements in serum sodium levels after saline hydration and fludrocortisone administration further supported the diagnosis

RESUMO

Cerebral salt-wasting syndrome (CSWS) is a rare disease characterized by a extracellular volume depletion and hyponatremia induced by marked natriuresis. It is mainly reported in patients who experience a central nervous system insult, such as cerebral hemorrhage or encephalitis. The syndrome of inappropriate antidiuretic hormone secretion is a main cause of severe hyponatremia after hematopoietic stem cell transplantation, whereas CSWS is rarely reported. We report 3 patients with childhood acute leukemia who developed CSWS with central nervous system complication after hematopoietic stem cell transplantation. The diagnosis of CSW was made on the basis of severe hyponatremia accompanied by increased urine output with clinical signs of dehydration. All patients showed elevated natriuretic peptide and normal antidiuretic hormone. Aggressive water and sodium replacement treatment was instituted in all 3 patients and 2 of them were effectively recovered, the other one was required to add fludrocortisone administration.

RESUMO

Orthostatic hypotension (OH) occurs when mechanisms for the regulation of orthostatic BP control fails. Such regulation depends on the baroreflexes, normal blood volume, and defenses against excessive venous pooling. OH is common in the elderly and is associated with an increase in mortality rate. There are many causes of OH. Aging coupled with diseases such as diabetes and Parkinson's disease results in a prevalence of 10-30% in the elderly. These conditions cause baroreflex failure with resulting combination of OH, supine hypertension, and loss of diurnal variation of BP. The treatment of OH is imperfect since it is impossible to normalize standing BP without generating excessive supine hypertension. The practical goal is to improve standing BP so as to minimize symptoms and to improve standing time in order to be able to undertake orthostatic activities of daily living, without excessive supine hypertension. It is possible to achieve these goals with a combination of fludrocortisone, a pressor agent (midodrine or droxidopa), supplemented with procedures to improve orthostatic defenses during periods of increased orthostatic stress. Such procedures include water bolus treatment and physical countermaneuvers. We provide a pragmatic guide on patient education and the patient-orientated approach to the moment to moment management of OH.

RESUMO

Hyperkalemia is often detected in young infants, particularly in association with acute pyelonephritis or a urinary tract anomaly. Cases of hyperkalemia in this population may also be due to transient pseudohypoaldosteronism, or immaturity of renal tubules in handling potassium excretion. Symptoms of hyperkalemia are non-specific, but are predominantly related to skeletal or cardiac muscle dysfunction, and can be fatal. Therefore, treatment has to be initiated immediately. Administration of fludrocortisone for hyperkalemia is appropriate in cases with hypoaldosteronism, but is challenging in young infants with hyperkalemia due to renal tubular immaturity, without pseudohypoaldosteronism. We report the case of a 25-day-old male presenting with persistent hyperkalemia with normal serum aldosterone, who was admitted with a first episode of pyelonephritis and unilateral high-grade vesicoureteral reflux. The patient was treated successfully with fludrocortisone.

RESUMO

X-linked adrenal hypoplasia congenita is caused by the mutation of DAX-1 gene (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1), and can occur as part of a contiguous gene deletion syndrome in association with glycerol kinase (GK) deficiency, Duchenne muscular dystrophy and X-linked interleukin-1 receptor accessory protein-like 1 (IL1RAPL1) gene deficiency. It is usually associated with hypogonadotropic hypogonadism, although in rare cases, it has been reported to occur in normal puberty or even central precocious puberty. This study addresses a case in which central precocious puberty developed in a boy with X-linked adrenal hypoplasia congenita who had complete deletion of the genes DAX-1, GK and IL1RAPL1 (Xp21 contiguous gene deletion syndrome). Initially he was admitted for the management of adrenal crisis at the age of 2 months, and managed with hydrocortisone and florinef. At 45 months of age, his each testicular volumes of 4 mL and a penile length of 5 cm were noted, with pubic hair of Tanner stage 2. His bone age was advanced and a gonadotropin-releasing hormone (GnRH) stimulation test showed a luteinizing hormone peak of 8.26 IU/L, confirming central precocious puberty. He was then treated with a GnRH agonist, as well as steroid replacement therapy. In Korea, this is the first case of central precocious puberty developed in a male patient with X-linked adrenal hypoplasia congenita.

RESUMO

OBJECTIVE: The protocols for glucocorticoid replacement in children with salt wasting 21-hydroxylase deficiency are well established; however, the current recommendation for mineralocorticoid replacement is general and suggests individualized dose adjustments. This study aims to retrospectively review the 9-∝-fludrocortisone dose regimen in salt wasting 21-hydroxylase deficient children who have been adequately treated during infancy. METHODS: Twenty-three salt wasting 21-hydroxylase deficient patients with good anthropometric and hormonal control were followed in our center since diagnosis. The assessments of cortisone acetate and 9-∝-fludrocortisone doses, anthropometric parameters, and biochemical and hormonal levels were rigorously evaluated in pre-determined intervals from diagnosis to two years of age. RESULTS: The 9-∝-fludrocortisone doses decreased over time during the first and second years of life; the median fludrocortisone doses were 200 µg at 0-6 months, 150 µg at 7-18 months and 125 µg at 19-24 months. The cortisone acetate dose per square meter was stable during follow-up (median = 16.8 mg/m²/day). The serum sodium, potassium and plasma rennin activity levels during treatment were normal, except in the first month of life, when periodic 9-∝-fludrocortisone dose adjustments were made. CONCLUSIONS: The mineralocorticoid needs of salt wasting 21-hydroxylase deficient patients are greater during early infancy and progressively decrease during the first two years of life, which confirms that a partial aldosterone resistance exists during this time. Our study proposes a safety regiment for mineralocorticoid replacement during this critical developmental period.

RESUMO

Background: Patients with postural orthostatic tachycardia syndrome (POTS) report dizziness, lightheadedness, weakness, blurred vision, and fatigue upon standing. The diagnosis of the syndrome is made when an orthostatic intolerance and tachycardia appear in the standing position. Aim: To report 15 patients with POTS. Material and Methods: Review of Tilt test reports in a period of 15 years. Those reports in which orthostatic postural tachycardia and symptoms compatible with POTS appeared, were selected for analysis. Results: We identified 15 patients (3.1% of all positive Tilt test reports) with compatible signs and symptoms. There was a lag of 8 -10 years between the onset of symptoms and the time of diagnosis. Most patients complained of orthostatic intolerance, dizziness and frequent fainting. Orthostatic tachycardia and symptoms occurred on average after 2.9 and 6.1 minutes, respectively,of staying in the standing position. These patients had a high frequency of family history of syncope orpresyncope (66% frequency) and hyper mobility syndrome (53% prevalence). Only 33% of the patients reported relief of their symptoms after being treated (most of them with fludrocortisone). Most patients that reported little or no relief, did not use medications or were treated for a short period. Conclusions: POTS syndrome is uncommon but disturbs quality of life of those who suffer it. Its association with hyper mobility syndromes must be investigated.

RESUMO

Cerebral salt wasting is characterized by inappropriate natriuresis and volume contraction with associated cerebral pathology. It is distinct from the syndrome of inappropriate antidiuretic hormone secretion, which is characterized by inappropriate retention of free water. We report a patient with a porencephalic cyst who developed cerebral salt wasting. His initial treatment was supplementation of water and salt, which did not improve natriuresis or volume contraction. Fludrocortisone administration effectively managed the cerebral salt wasting.

RESUMO

Adrenal myelolipoma is an uncommon non-functioning tumor that is composed of variable amounts of mature adipose tissue and scattered islands of hematopoietic elements, including erythroid, myeloid, lymphoid series, and megakaryocytes. Adrenal myelolipoma should be differentiated from other fat-containing adrenal masses, such as teratoma, lipoma, and liposarcoma. This case report describes a 50-year-old adult who was raised as a male and developed giant adrenal myelolipomas that presented as symptomatic adrenal masses, and which were misdiagnosed as liposarcoma on radiologic examination. The patient had been raised as a male despite ambiguous genitalia, and a thorough investigation was never carried out because of his poor socioeconomic status. Physical examination showed profound short stature (<-3.0 standard deviation score), hyperpigmentation, and a micropenis without palpable gonads. Both a uterus and ovaries were evident in the pelvic cavity on abdominopelvic computed tomography. Adrenocorticotropic hormone stimulation tests confirmed adrenal insufficiency. Steroid replacement therapy was initiated before bilateral adrenalectomy and the histologic findings indicated myelolipoma. The patient's karyotype was 46, XX and mutation analysis of the CYP21A2 gene identified compound heterozygosity consisting of p.I173N and p.Q319*. The patient was treated with once-daily 0.5 mg dexamethasone and once-daily 0.1 mg fludrocortisone. Because the subject had been raised as a male, additional procedures such as an oophorohysterectomy are currently under consideration. We here describe an adrenal myelolipoma in this case that was complicated by a 21-hydroxylase deficiency. We conclude from our analysis that patients with congenital adrenal hyperplasia should be screened for incidental adrenal masses to avoid unnecessary surgical procedures.

RESUMO

Adrenal insufficiency is a life-threatening disorder which must be treated with glucocorticoid replacement and needs permanent dose adjustment during patient's different somatic situations. Insufficient glucocorticoid doses result in adrenal crisis and must be treated with intravenous hydrocortisone. The patient was known with Adrenal insufficiency and was treated optimally with fludrocortisone and prednisolone since seven years with no history of adrenal crisis. The patient was admitted with abdominal pain, weakness, fatigue and nausea developed 3-4 days after taking psyllium, a bulking agent, prescribed by a surgeon to diagnose anal fissure. Detailed medical history, physical examinations, laboratory and imaging examinations did not approve any other cause of adrenal crisis. Psyllium may interfere with gastrointestinal absorption of prednisolone and/or fludrocortisone and trigger acute adrenal crisis in patients with adrenal insufficiency

RESUMO

Bilateral spontaneous renal rupture is a rare event that has been documented in only a few reports. We report a spontaneous, but not simultaneous rupture of both kidneys in a 64-year-old man with end-stage renal disease who had been treated with hemodialysis for 78 months. He complained of sudden left flank pain. Abdominal computed tomography (CT) revealed a huge perirenal hematoma with multiple renal cysts. The patient underwent an urgent left nephrectomy and was diagnosed as multiple acquired renal cysts with rupture and focal incidental papillary renal cell carcinoma. Twenty-two days after the left nephrectomy, he complained of sudden right flank pain and abdominal CT showed another massive perirenal hematoma. The patient underwent a right nephrectomy and was diagnosed as renal cyst rupture with perirenal hemorrhage. However, there was no evidence of renal cell carcinoma in the right kidney. Postural hypotension and frequent hypotensive episodes developed during hemodialysis several months after both nephrectomies. He was diagnosed as primary adrenal insufficiency with rapid adrenocorticotropic hormone (ACTH) stimulation test and the level of plasma ACTH and was treated with prednisolone and fludrocortisone. The patient died of acute myocardial infarction 32 months after bilateral nephrectomies.

RESUMO

The authors report two cases of adrenal insufficiency secondary to infiltration of the adrenal glands by Paracoccidioides brasiliensis. The first patient had been treated for a chronic multifocal form of paracoccidiodomycosis 11 years ago. The diagnosis of the mycosis was done simultaneous with that of the adrenal insufficiency in the second patient. In both patients the diagnosis was done by direct visualization of fungus in adrenal biopsies. They were treated with hormonal supplements and itraconazol by 12 and six months, without relapses during the follow-up period.


Os autores apresentam dois casos de insuficiência supra-renal secundária à infiltração das adrenais pelo Paracoccidioides brasiliensis. O primeiro paciente tinha sido tratado de paracoccidioidomicose crônica multifocal 11 anos atrás. No segundo paciente, o diagnóstico da micose foi feito de forma simultânea com o da insuficiência adrenal. Em ambos os pacientes, o diagnóstico foi feito pela visualização direta do fungo nas biopsias adrenais. Eles foram tratados com suplementos hormonais com itraconazol por seis a 12 meses, sem recaídas durante o período de acompanhamento.
