A 58-year-old right-handed woman presented to our institution with a 1-month history of polydipsia and polyuria. She had a remote history of neurofibroma excision by dermatology and, on examination, was noted to meet the clinical diagnostic criteria for neurofibromatosis type 1. Laboratory investigations revealed hypernatraemia and elevated serum osmolality, accompanied by reduced urinary osmolality. A subsequent water deprivation test confirmed central diabetes insipidus, which responded to treatment with desmopressin...

REVIEW
Karl-Erik Andersson, Philip Van Kerrebroeck
PURPOSE OF REVIEW: To assess current pharmacological principles used for treatment of nocturia/nocturnal polyuria. RECENT FINDINGS: The pathophysiology of nocturia is often multifactorial, but two main mechanisms have been identified, occurring alone or in combination: low functional bladder capacity and nocturnal polyuria. The multifactorial pathophysiology not only implies several possible targets for therapeutic intervention but also means that it is unlikely that one treatment modality including drugs will be successful in all patients...

OBJECTIVES: Cisplatin (CIS) is an effective antitumor drug. However, its clinical use is limited due to nephrotoxicity. l-Carnitine and vitamin C are both natural antioxidant that can be obtained from diets. This study investigated the effects of l-carnitine and/or vitamin C in rats against cisplatin-induced nephrotoxicity. METHODS: Twenty-five male Wistar rats were divided into 5 groups of 5 rats each. Group 1, normal control. Group 2, positive control, received cisplatin (10 mg/kg/day intraperitoneally [i...

BACKGROUND: Lithium remains first choice as maintenance treatment for bipolar affective disorder. Yet, about half of all individuals may stop their treatment at some point, despite lithium's proven benefits concerning the prevention of severe affective episodes and suicide. METHODS: Retrospective cohort study in the Swedish region of Norrbotten into the causes of lithium discontinuation. The study was set up to (1) test whether patients with bipolar affective disorder or schizoaffective disorder, treated with lithium maintenance therapy, were more likely to discontinue lithium because of adverse effects than lack of therapeutic effectiveness, (2) explore gender differences, (3) understand the role of diagnosis and (4) identify who, patient or doctor, took the initiative to stop lithium...

BACKGROUND: It has been reported that mutations in arginine vasopressin type 2 receptor (AVPR2) cause congenital X-linked nephrogenic diabetes insipidus (NDI). However, only a few cases of AVPR2 deletion have been documented in China. METHODS: An NDI pedigree was included in this study, including the proband and his mother. All NDI patients had polyuria, polydipsia, and growth retardation. PCR mapping, long range PCR and sanger sequencing were used to identify genetic causes of NDI...

BACKGROUND: Gestational diabetes insipidus (GDI) is a rare endocrine complication during pregnancy that is associated with vasopressinase overproduction from the placenta. Although increased vasopressinase is associated with placental volume, the regulation of placental growth in the later stage of pregnancy is not well known. CASE PRESENTATION: A 16-year-old pregnant woman was urgently transferred to our hospital because of threatened premature labor when the Kumamoto earthquakes hit the area where she lived...

Lithium is widely used in treatment of bipolar affective disorders, but often causes nephrogenic diabetes insipidus (NDI), a disorder characterized by severe urinary concentrating defects. Lithium-induced NDI is caused by lithium uptake by collecting duct principal cells and altered expression of aquaporin-2 (AQP2), which are essential for water reabsorption of tubular fluid in the collecting duct. Sex hormones have previously been shown to affect the regulation of AQP2, so we tested whether tamoxifen (TAM), a selective estrogen receptor modulator, would attenuate lithium-induced alterations on renal water homeostasis...

Neonatal severe hyperparathyroidism (NSHPT) is a rare autosomal recessive disease. Children present within the first 6 months of life and more commonly in the first few weeks. Common presentation is poor feeding, polyuria, dehydration, lethargy, failure to thrive, hypotonia, gastrointestinal dysmotility, osteopenia and symptoms of respiratory distress due to a poorly developed chest cage. We present a case of a 2-month old girl with severe hypercalcemia and hyperparathyroidism. She was found to have a novel homozygous mutation in the acceptor splicing site of intron 4 (c...

Nephropathy is a well-characterized complication of type 1 diabetes (T1D), resulting in proteinuria and urinary loss of micronutrients. We previously found that a whole egg-based diet maintained vitamin D balance in type 2 diabetic rats despite excessive urinary losses due to nephropathy. The goal of this study was to investigate the impact of whole egg consumption in T1D rats. Sprague-Dawley rats were randomly assigned to T1D or nondiabetic control groups and fed a casein or whole egg-based diet for 32 days...

In the country presently, preclinical medical students are not routinely exposed to real patients. Thus, when they start clinical postings, they are found to have poor clinical reasoning skills. Simulated virtual patients (SVPs) can improve clinical skills without endangering real patients. This pilot study describes the development of two SVPs in endocrine physiology and their validation in terms of acquisition of clinical knowledge and student engagement. Two SVPs, Nandini Sharma (unintentional weight gain) and Sunil Yadav (polyuria), were created and published on the i-Human Patients platform through an iterative, interdisciplinary, and transdisciplinary collaborative process using the conceptual framework of Kim et al...

Central diabetes insipidus is a rare disease in children caused by a deficiency of vasopressin. Its main clinical manifestations are polyuria and polydipsia. Brain malformations are one of the main causes. Desmopressin is the synthetic drug of choice for the treatment. One of the routes of administration is sublingual and its use in infants is very limited. We describe two infants with central diabetes insipidus and hydranencephaly who were successfully treated with sublingual desmopressin.

BACKGROUND/PURPOSE: Common variable immunodeficiency (CVID) is typically characterized by hypogammaglobulinemia and often but not always recurrent infections. Paradoxically, 8-22% of patients with CVID develop granulomatous disease. Granulomata have been described in many organs including the lungs, skin, liver, spleen, kidneys, eyes, lymph nodes, and intestines. Data about central nervous system (CNS) involvement in CVID are extremely rare. We aim to describe a case series and include an extensive literature review of CNS involvement in CVID to understand the different features and patterns of the disease...

INTRODUCTION: Diabetes insipidus is characterized by hypoosmotic polyuria related to deficiency of arginine-vasopressin (AVP) secretion (central diabetes insipidus, CDI) or renal insensitivity to AVP (nephrogenic diabetes insipidus, NDI). The water deprivation test with assessment of AVP activity is currently the gold standard for differential diagnosis in patients presenting polyuria-polydipsia syndrome. Nevertheless, it can be dangerous without proper surveillance and its interpretation may be challenging...

BACKGROUND: Arterial hypertrophy and interstitial fibrosis are important characteristics in kidneys of angiotensinogen-knockout (Atg -/-) mice. In these mice, which exhibit polyuria and hypotension, sympathetic nerve signaling is estimated to be compensatorily hyperactive. Furthermore, transforming growth factor (TGF)-β1 is overexpressed in mice kidneys. To determine whether sympathetic nerve signaling and TGF-β1 exacerbate arterial hypertrophy and interstitial fibrosis, intervention studies of such signaling are required...
