Summary
Central diabetes insipidus (CDI) in a young girl was diagnosed and treated with desmopressin. This case highlights the importance of differential diagnosis and family involvement in managing CDI.
Area of Science:
- Pediatric Endocrinology
- Neuroendocrinology
Background:
- Polyuria and polydipsia are symptoms of several conditions, including psychogenic polydipsia, central diabetes insipidus (CDI), and nephrogenic diabetes insipidus.
- CDI can result from various lesions, genetic defects, or be idiopathic, affecting vasopressin (AVP) production.
Observation:
- A 5.5-year-old female presented with polyuria and polydipsia, prompting an endocrinology referral.
- Hormonal tests confirmed CDI with normal anterior pituitary function; MRI revealed absent posterior pituitary hyperintensity.
Findings:
- The patient was diagnosed with CDI and initiated on desmopressin (Minirin) therapy.
- Follow-up showed the patient in good condition with stable hydro-electrolytic balance, normal growth, and consistent MRI findings.
Implications:
- This case underscores the challenges in differential diagnosis for polyuria and polydipsia.
- Emphasizes the critical role of comprehensive follow-up, including family participation, in managing pediatric CDI.

01:29Diabetes Insipidus I: Introduction
Definition Diabetes insipidus is a disorder marked by the production of large amounts of dilute urine because of impaired vasopressin production, release, or kidney response. The lack of effective vasopressin action limits water reabsorption in the renal collecting ducts, which leads to excessive urinary water loss and intense thirst.Clinical PresentationIndividuals with diabetes insipidus report persistent thirst and very high urine output. In severe cases, fluid intake can reach up to 20...
01:15Diabetes: Symptoms, Diagnosis, and Complications
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
01:22Diabetes Insipidus II: Pathophysiology
Normally, water balance is maintained through three interconnected mechanisms: the hypothalamic thirst center, the synthesis and release of antidiuretic hormone (ADH, or vasopressin), and the kidneys' responsiveness to this hormone. ADH is synthesized in the hypothalamus, released from the posterior pituitary, and acts on the distal nephron, allowing water reabsorption and concentrated urine production.Diabetes Insipidus and Its TypesIn diabetes insipidus (DI), this regulatory system is...
01:29Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
