【Objective】 To investigate the urinary tract characteristics of diabetes insipidus (DI) complicated with upper urinary tract dilatation (UUTD), and to summarize the treatment experience. 【Methods】 The clinical data of 28 DI patients treated in China Rehabilitation Research Center were retrospectively analyzed with UUTD and all urinary tract dysfunction (AUTD) systems to evaluate the urinary tract characteristics. The relevant laboratory results, video-urodynamic recordings (VUDS), UUTD, neurophysiologic tests, treatment regimens and follow-up data were summarized. 【Results】 There were 21 DI cases (75.0%) and 7 cases of DI with neurogenic bladder (NB). Polyuria, polydipsia, urine specific gravity, urine osmotic pressure and water deprivation vasopressin test had diagnostic value for DI. In addition, detailed history, neurological examination, VUDS and neurophysiologic tests had significant diagnostic value for DI with NB. Enterocystoplasty was recommended for 2 DI with NB patients with poor bladder capacity, compliance and renal impairment. For the remaining 26 patients, individualized medication combined with bladder neck incision and appropriate bladder management, including intermittent catheterization, catheter indwelling and regular voiding, achieved satisfactory results. High serum creatinine decreased from (269.8±105.7)μmol/L to (164.4±90.2)μmol/L in 13 patients with abnormal renal function. Forty-eight dilated ureters showed significant improvement in the UUTD grade, and the median grade decreased from 3 to 2. 【Conclusion】 Bladder distension, trabeculation and decreased or absent sensations were common features for DI patients with UUTD. Individualized therapy by medication combined with appropriate bladder management can improve the dilatation and renal function.

ABSTRACT Objective: Quality of Life (QoL) has been a multifactorial concerning issue in oncology. We aimed to inspect the pre-operative QoL among patients with craniopharyngioma and to explore the potential correlations between parameters of QoL and clinical indices. Subjects and methods: We enrolled a total of 109 patients with craniopharyngioma. We utilized Short Form 36 (SF-36), Symptom Check List-90, Generalized Anxiety Disorder Questionnaire scale (GAD7), Patient Health Questionnaire Depression (PHQ9) and Pittsburgh Sleep Quality Index to prospectively evaluated their QoL. Parameters of QoL along with clinical indices were compared among sub-groups divided according to Puget classification. Correlation analyses and regression analyses were performed to detect influential determinants to self-reported wellness. Results: Patients presented impaired QoL compared with general population ( p < 0.001), as assessed by SF-36. Correlation analyses indicated the detrimental influence resulting from central diabetes insipidus (CDI). Multivariate linear regression unveiled the adverse effect of CDI on Mental Component Summary (coefficient = −13.869, p = 0.007), GAD7 total score (coefficient = 2.072, p = 0.049) as well as PHQ9 total score (coefficient = 3.721, p = 0.001). Multivariate logistic regression verified CDI as a risk factor of developing depressive symptoms (OR = 6.160, p = 0.001). Conclusion: QoL of patients with craniopharyngioma was remarkably compromised before operation. CDI exerted detrimental influences on patients' QoL and it might serve as a marker for early identification of patients at risk of depression.

Abstract Introduction : Primary hypophysitis (PH) is a rare disease that represents a challenge among differential diagnosis and management. Our aim was to describe clinical characteristics, diagnostic criteria and different treatment outcomes in patients with PH. Multicentric, retrospective study. Clinical presentation, endocrine function, magnetic resonance imaging findings, visual field defects at diagnosis and treatment outcomes were recorded. Methods : Twenty-eight patients (23 women), with PH were included. Median age: 37. Results : The most frequent symptoms: headache: 68%, polyuria-polydipsia: 50% and visual disturbances: 48%. At diagnosis, anterior pituitary deficiency was present in 71%, being hypogonadotrophic hypogonad ism the most frequent manifestation. The radiological findings: symmetric lesion: 78.5%, homogeneous en hancement: 78.5% and pituitary stalk thickening: 70%. Association with pregnancy or puerperium was found in 4/23 women (17%). Fourteen patients did not receive any treatment ("wait and see" group), 8 underwent surgery for mass reduction or resection and 6 were treated with immunosuppression therapy. Among 15 patients with histopathological diagnosis, 9 were lymphocytic hypophysitis, 5 IgG4 related hypophysitis and 1 xanthomatous hypophysitis. Thirteen were di agnosed by established clinical criteria. Mass reduction was observed in 43% of "wait and see group" patients, 62.5% of operated patients and 50% with immuno suppression therapy. Compressive symptoms showed improvement in the 3 groups, with modest effect on anterior pituitary function, diabetes insipidus did not resolve in any patients. Discussion : In patients without severe compressive symptoms, we adopted a "wait and see" approach. In patients with uncertain diagnosis of PH or severe com pressive symptoms, transsphenoidal surgery was the best option.

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.
Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Objective:To investigate the clinical and genetic characteristics, pathogenesis and treatment strategy of congenital nephrogenic diabetes insipidus(CNDI)combined with hyperuricemia.Methods:The clinical manifestations and laboratory data of an infant patient diagnosed as CNDI with hyperuricemia and his family members were collected and retrospectively analyzed. Whole exome sequencing(WES)was applied to detect the proband′s genome variation of each exon and suspected variants of AVPR2 and ABCG2 were verified by PCR-Sanger sequencing of members from his pedigree. Furthermore, we retrospectively collected the serum uric acid levels of patients(≤14-year-old) with CNDI in the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2022.Results:The proband was clinically diagnosed with CNDI and the rest of the family members had no symptoms of polydipsia or polyuria. In addition to the proband, his father was also suffered from hyperuricemia. WES showed that the proband carried a hemizygous AVPR2 gene variation(p.S331R)and a heterozygous ABCG2 gene variation(p.N308K). The former was X-linked recessive inheritance from his mother, and the latter was autosomal dominant inheritance from the father. Fraction excretion of uric acid(FEUA)of the proband and his father with hyperuricemia were 3.1% and 2.7%, respectively. Twelve children(≤14-year-old)were diagnosed with CNDI from the respective study. Among all the cases, 11 patients were male and 1 was female, ranging from 3-month to 14-year-old. Five patients were accompanied with hyperuricemia.Conclusion:Children with CNDI may be complicated with hyperuricemia, and the regimen of hydrochlorothiazide combined with benzbromarone is effective. The pathogenicity of the AVPR2 gene variation(p.S331R)and ABCG2 gene variation(p.N308K)in this pedigree needs to be further studied.

Objective:To improve clinicians' understanding of congenital nephrogenital diabetes insipidus (CNDI) and to reduce missed and misdiagnosis. Methords Based on the literature, the clinical data and gene mutation of 2 patients with CNDI who were admitted to the Department of Endocrinology and Metabolism of the First Affiliated Hospital of Henan University of Science and Technology on July 30, 2020 were analyzed retrospectively. Results:(1) The presentee, 4 years old, had irritable thirst, polydipsia and polyuria for more than 3 years. The sister, 2.5 years old, had irritable thirst, polydipsia and polyuria for more than 2 years. The clinical diagnosis was “CNDI”, and the symptoms improved after treatment with hydrochlorothiazide. (2) The genetic test revealed that the congenital nephrogenic uremia and her sister had a heterozygous mutation of c.170A>C (p.Q57P) and c.211G>A (p.Vl71M) in the aquaporin-2 gene, and the mother carried the AQP2 gene. c.170A>C(p.Q57P) mutation.Conclusion:CNDI is a rare disease. Early diagnosis and treatment can improve the prognosis of patients to the greatest extent, and prenatal diagnosis can guide eugenics.

Objective To investigate the level of serum uric acid in patients with diabetes insipidus (DI),summarize the clinical characteristics of central diabetes insipidus (CDI) patients with hyperuricemia (HUA),and analyze the factors affecting the level of serum uric acid in the patients with CDI. Methods The clinical data of DI patients admitted to Peking Union Medical College Hospital from 2018 to 2021 were retrospectively analyzed.The patients were assigned into a child and adolescent group (≤ 18 years old) and an adult group (>18 years old) according to their ages.The demographic and biochemical data between two groups of patients with and without HUA were compared.Spearman correlation analysis and multiple linear regression analysis were performed to analyze the correlations between serum uric acid level and other factors. Results Among the 420 DI patients,411 patients had CDI (97.9%),including 189 patients with HUA (46.0%).Thirteen (6.9%) out of the 189 CDI patients with HUA presented the disappearance of thirst.The prevalence of HUA in children and adolescents was higher than that in adults (χ2=4.193,P=0.041).The level of serum uric acid in the CDI patients with HUA and disappearance of thirst was higher than those without disappearance of thirst (U=2.593,P=0.010).The multiple linear regression predicted serum creatinine (β=0.472,95%CI=2.451-4.381,P<0.001) and body mass index (β=0.387,95%CI=6.18-12.874,P<0.001) as the independent risk factors of serum uric acid level increment in children and adolescents,while serum creatinine (β=0.361,95%CI=1.016-1.785,P<0.001),body mass index (β=0.208,95%CI=2.321-6.702,P<0.001),triglyceride (β=0.268,95%CI=12.936-28.840,P<0.001),and total cholesterol (β=0.129,95%CI=2.708-22.250,P=0.013) were the independent risk factors in adults. Conclusions The patients with CDI were more likely to have HUA,and the prevalence of HUA in children and adolescents was higher than that in adults.Body mass index,serum creatinine,triglyceride,total cholesterol,and disappearance of thirst were the risk factors for the increased level of serum uric acid in CDI patients.

ABSTRACT Diabetes insipidus is a rare disorder characterized by the inability to concentrate urine, which results in hypotonic urine and increased urinary volume. It may occur because of antidiuretic hormone deficiency or resistance to its action in the renal tubules. When there is a deficiency in the synthesis of antidiuretic hormones, diabetes insipidus is called central; when there is resistance to its action in the renal tubules, it is said to be nephrogenic. We report a case of idiopathic partial central diabetes insipidus and highlight the management and treatment of the disease.

RESUMEN La diabetes insípida central se produce por déficit de síntesis o secreción de hormona antidiurética. Es una entidad de muy baja prevalencia que se puede ver asociada a hipofisitis linfocítica y silla turca vacía. Sin embargo, el diagnóstico histopatológico solo se realiza cuando es necesaria la cirugía debido a un compromiso neurológico. Se presentó el caso de un paciente masculino de 41 años que acudió a consulta porque orinaba frecuentemente y bebía mucha agua. Se le realizó prueba de supresión de líquidos, seguida de prueba de la vasopresina, que fueron consistente con el diagnóstico de diabetes insípida central. La resonancia magnética de la hipófisis reveló silla turca vacía parcial y signos de infundíbulo-neurohipofisitis, coincidencia que ha sido escasamente reportada. En el seguimiento se evidenció hipogonadismo hipogonadotrópico y baja reserva adrenal. Se indicó tratamiento de reemplazo hormonal con desmopresina y testosterona, con lo cual el paciente ha mantenido buena calidad de vida. Se concluye que la diabetes insípida puede ser la primera manifestación de una panhipofisitis. La asociación de estas enfermedades con el síndrome de silla turca vacía es infrecuente, pero puede ser el curso natural de la enfermedad.
ABSTRACT Central diabetes insipidus is caused by a deficiency in the synthesis or secretion of antidiuretic hormone. It is a very low prevalence entity that can be seen associated with lymphocytic hypophysitis and empty sella turcica. However, histopathological diagnosis is only made when surgery is necessary due to neurological compromise. The case of a 41-year-old male patient who came to the clinic because he urinated frequently and drank a lot of water was presented. A fluid suppression test was performed, followed by a vasopressin test, the results of which were consistent with a diagnosis of central diabetes insipidus. Magnetic resonance imaging of the pituitary gland revealed partial empty sella turcica and signs of infundibulo-neurohypophysitis, a coincidence that has been rarely reported. In the follow-up, hypogonadotropic hypogonadism and low adrenal reserve were revealed. Hormone replacement treatment with desmopressin and testosterone was indicated, with which the patient has maintained a good quality of life. It is concluded that diabetes insipidus may be the first manifestation of panhypophysitis. The association of these diseases with the empty sella syndrome is rare, but it may be the natural course of the disease.

Abstract Lithium carbonate is a commonly prescribed drug for bipolar disorders. In addition to its action on the central nervous system, lithium has systemic effects on multiple organs such as kidney, heart, motor end plate, thyroid and parathyroid glands. It can cause hypothyroidism, hyperthyroidism, goiter and oph thalmopathy by different mechanisms. It increases intrathyroid iodine content or compete for iodine transport, resulting in low iodine uptake by the thyroid. It also inhibits the coupling of iodotyrosine residues to form iodothy ronines and inhibits the release of T4 and T3. Lithium has direct actions on parathyroid glands by antagonizing the calcium sensing receptor, which may induce hypercalcemia or even hyperparathyroidism, requiring surgery in some cases. Furthermore, it inhibits the expression of aquaporins, mainly aquaporin 2, in the renal collecting tubule by unknown mechanisms leading to nephrogenic diabetes insipidus. This adverse effect is usually reversible after drug withdrawal. However, some patients may present irreversible kidney damage due to chronic interstitial nephropathy.
Resumen El carbonato de litio es un fármaco que se prescribe comúnmente para el tratamiento de trastornos bipolares. Además de su acción sobre el sistema nervioso central, el litio tiene repercusiones sistémicas, afectando a múltiples órganos como el riñón, el corazón, la placa motora terminal y glándulas tiroides y paratiroides. Puede causar hipotiroidismo, hipertiroidismo, bocio y oftalmopatía por diferentes mecanismos; también aumentar el contenido de yodo intratiroideo o competir por el transporte de yodo, lo que resulta en una baja captación tiroidea de yodo. Inhibe el acoplamiento de residuos de yodotirosina para formar yodotironinas e inhibe la liberación de T4 y T3. Tiene acciones directas sobre las glándulas paratiroides antagonizando el receptor sensor de calcio, lo que puede inducir hipercalcemia e incluso hiperparatiroidismo, y puede requerir cirugía en algunos casos. Inhibe la expresión de acuaporinas en el túbulo colector renal, prin cipalmente acuaporina 2, por mecanismos que aún no se conocen, produciendo diabetes insípida nefrogénica; este efecto adverso suele ser reversible tras la suspensión del fármaco. Sin embargo, algunos pacientes pueden presentar daño renal irreversible por nefropatía intersticial crónica.

Diagnosis of central diabetes insipidus (CDI) requires a high index of clinical suspicion, especially when it manifests as a coexisting condition like traumatic brain injury or following neurosurgery. We would like to report a rare case of necrotizing infundibulohypophysitis (NIH) as a cause of CDI in a 21-year-young male who presented with a severe progressive headache not responding to routine analgesics followed by vomiting, altered sensorium. His baseline blood investigations were normal including his cerebrospinal fluid examination, plain and contrast magnetic resonance imaging (MRI) scan. The patient partially responded to the treatment of headache and after 2 days, complained of polyuria with severely reduced serum sodium level. A repeat plain and MRI of the brain was done which showed classical findings of NIH with CDI which we discuss along with the differential diagnosis and its prognosis

The data of 10 patients with pituitary metastases were retrospectively analyzed, including tumor origin, clinical features, imaging characteristics, diagnosis and differential diagnosis, treatment and prognosis. The results showed that the average age of 10 patients at the time of consultation was 62.0 years. Nine metastases were originated from lung cancer and one from breast cancer. All patients started with central diabetes insipidus, and some of them accompanied with hypopituitarism, as well as occupancy manifestations such as headache, blurred vision, etc. MRI showed abnormalities in the pituitary stalk and posterior pituitary, four of which showed characteristic " dumbbell-shaped" changes. Three patients with epidermal growth factor receptor(EGFR)-mutated lung adenocarcinoma revealed improvement in both primary lesion and pituitary metastases after targeted therapy.

La hipofisitis autoinmune es un cuadro caracterizado por la infiltración linfocítica de la hipófisis que produce deficiencia de una o más hormonas, tanto de la adenohipófisis como de la neurohipófisis. Para el diagnóstico, es necesario un alto índice de sospecha, más aún considerando la relación temporal con el embarazoo el parto. Las características clínicas e imagenológicas sugieren el diagnóstico. A pesar que el diagnóstico definitivo es por biopsia, esta no se suele realizar por los potenciales efectos adversos del procedimiento. Presentamos un caso que describe la forma de manifestación de la enfermedad y las características imagenológicas típicas en la resonancia magnética nuclear.
Autoimmune hypophysitis is a condition characterized by lymphocytic infiltration of the pituitary resulting in deficiency of one or more hormones of both the adenohypophysis and the neurohypophysis. For diagnosis, a high index of suspicion is necessary, even more so considering the temporal relationship with pregnancy or childbirth. Clinical and imaging features are suggestive of the diagnosis. Although the definitive diagnosis is by biopsy, this is not usually performed because of the potential adverse effects of the procedure. We present a case describing the form of manifestation of the disease and the typical imaging features on magnetic resonance imaging.

The purpose of this study was to improve the ability to visualize and diagnose congenital nephrogenic diabetes insipidus (CNDI). The clinical manifestations, laboratory examination findings, imaging features and treatment outcomes of 22 patients with CNDI admitted to the First Affiliated Hospital of Zhengzhou University from May 2013 to May 2020 were retrospectively analyzed. Among the 22 patients with CNDI, 86.4% (19 cases) were male. The age of the 22 patients ranged from 2 months to 47 years old, in which 20 cases were younger than 30 years old and 2 cases were older than 30 years old. The clinical manifestations were polydipsia and polyuria, accompanied with various degrees of fever, defects in growth and development, and increased serum creatinine in some patients. Fifteen patients (68.2%) had different degrees of bilateral kidney and ureteral hydronephrosis, and increased residual urine volume in the bladder. Pituitary magnetic resonance imaging (MRI) enhanced scan showed that the high signal intensity in the posterior pituitary lobe was not detectable in 5 cases (22.7%), and blurred in 6 cases (27.3%). Seven tested patients were all found AVPR2 gene mutation. For patients with suspected CNDI, water-inhibiting vasopressin test and genetic testing should be performed in time so as to confirm diagnosis and treat as early as possible.

La diabetes insípida es el resultado de una secreción o acción reducidas de la hormona vasopresina, expresada clínicamente por un cuadro de poliuria-polidipsia. Los arbovirus pueden tener afinidad por el sistema nervioso y se ha demostrado que el Zika desencadena un trastorno autoinmune que ataca a las células nerviosas, lo que puede traer como consecuencia una diabetes insípida central. En la literatura médica nacional e internacional revisada no se reportan casos anteriores donde se vincule la diabetes insípida con el virus del Zika. Se presenta un caso a propósito de esta asociación: paciente femenina de 53 años, diagnosticada con infección por el virus del Zika dos semanas antes de comenzar con los síntomas sugestivos de diabetes insípida. El potencial neurotrópico del virus, así como los resultados en la resonancia magnética nuclear y la determinación de marcadores de autoinmunidad anti-ADNdc positivos, son elementos que apoyan la hipótesis de que la paciente presentó una posible hipofisitis autoinmune, como respuesta inflamatoria post-infección, desarrollando diabetes insípida central transitoria(AU)
Diabetes insipidus is the result of reduced secretion or action of the vasopressin hormone, which is clinically expressed by a polyuria-polydipsia picture. Arboviruses can have a nervous system affinity and Zika has been shown to trigger an autoimmune disorder that attacks nerve cells, which can result in central diabetes insipidus. The reviewed national and international medical literatures does not report previous cases linking diabetes insipidus with Zika virus. It is presented a case about this association: 53-year-old female patient diagnosed with Zika virus infection two weeks before starting symptoms suggestive of diabetes insipidus. The neurotropic potential of the virus, as well as the results in nuclear MRI and the determination of positive anti-ADNdc autoimmunity markers are elements that support the hypothesis that the patient had a possible autoimmune hypophysis, as a post-infection inflammatory response, developing transient central diabetes insipidus(AU)

SUMMARY INTRODUCTION: Nephrogenic diabetes insipidus (DI) is a polyuric and polydipsic syndrome and can have multiple causing factors. CASE DESCRIPTION: A 69-year-old woman with bipolar disorder medicated with lithium 400mg for 12 years on a daily basis. The patient was admitted, after psychiatric decompensation, with hypernatremia unresponsive to hypotonic iv fluids. The diagnosis of DI was made with high plasmatic osmolality measurement, low urine osmolality, and high levels of antidiuretic hormone. Full clinical recovery was possible with lithium suspension, hydration, and chlorthalidone. DISCUSSION: Although frequently used in the past, Lithium (Li) is nowadays rarely used in clinical practice for prolonged treatments because of its potentially devastating side effects. Clinicians must be aware of those side effects in order to prevent organ damage, mainly in patients with severe bipolar disease and precarious response to alternative treatments.
RESUMO INTRODUÇÃO: O diabetes insípido nefrogênico faz parte das síndromes poliúricas polidipsicas e pode ter múltiplos fatores causais. CASO CLÍNICO: Mulher de 69 anos, com doença bipolar medicada com lítio 400 mg por dia durante 12 anos. A doente foi internada, após descompensação da doença bipolar, por hipernatremia não responsiva a fluidoterapia hipotônica endovenosa. O diagnóstico de DI foi realizado com base na elevação da osmolaridade plasmática, baixa osmolaridade urinária e níveis elevados de hormona antidiurética. Verificou-se recuperação clínica completa com suspensão do lítio, hidratação e clorotalidona. DISCUSSÃO: Apesar do seu uso frequente no passado, o lítio (Li) é hoje em dia raramente utilizado na prática clínica por períodos prolongados pelos seus efeitos potencialmente devastadores. Os médicos devem ter em conta os potenciais efeitos secundários de forma a prevenir lesão de órgão em doentes com doença bipolar de difícil controle com outra terapêutica.

SUMMARY Checkpoint inhibitors have substantially improved the prognosis for patients with advanced malignancy. Treatment with immunomodulants has the ability to reactivate the immune system against tumor cells, but can also trigger the development of immune-related adverse events that reflects a loss of tolerance of the immune system for self-antigens. Regarding the endocrine system, thyroid and pituitary are the most frequent glands involved; in particular hypophysitis is commonly observed with anti-CTLA4 with a variable impaired anterior pituitary dysfunction (mainly ACTH and TSH dysregulation) while a posterior pituitary dysfunction has been rarely described. A 68-year-old man with a diagnosis of metastatic mesothelioma started in September 2016 first-line treatment with tremelimumab and durvalumab. After 3 cycles he presented sudden onset of polydipsia and polyuria without other symptoms. Diagnostic work-up, including a water deprivation test, established a diagnosis of central diabetes insipidus. Patient started sublingual desmopressin 60 mcg three times a day, that was subsequently increased up to 480 mcg/die. At magnetic resonance imaging the posterior lobe of pituitary gland did not show high signal intensity on T1-weighted images. After regression of diabetes insipidus symptoms under desmopressin, patient restarted cancer treatment and received additional 10 doses without worsening of endocrinological toxicity or further treatment-related toxicities, maintaining the same desmopressin dosage. Posterior pituitary dysfunction has been rarely observed in patients treated with immunomodulants. To our knowledge, this is the first observation of permanent central diabetes insipidus in patients treated with combined immune checkpoint inhibitors (tremelimumab and durvalumab).

Resumen El magnesio sérico es el "ion olvidado" en la práctica médica: la mayoría de veces no se tiene en cuenta en los estudios clínicos, sus alteraciones tienden a ser ignoradas y su aproximación terapéutica no está definida de forma adecuada. La sintomatologia producto de la hipomagnesemia es inespecífica y su aproximación diagnostica es compleja. Se presenta el caso de una paciente con hipomagnesemia sintomática severa asociada a daño renal por hipercalcemia durante la gestación.
Abstract Serum magnesium is the «forgotten ion¼ in medical practice. Most of the time it is not taken into account in clinical studies, its alterations tend to be ignored and its therapeutic approach is not well defined. The symptomatology produced by hypomagnesemia is nonspecific and its diagnostic approach is complex. We present the case of a pregnant patient with symptomatic hypomagnesemia secondary to renal damage due to hypercalcemia.
