Resumen
Este reporte de caso detalla un paciente con esquizofrenia paranoide que experimenta polidipsia psicógena e hiponatremia. Se probó la naltrexona, reduciendo con éxito los comportamientos de ingesta compulsiva de líquidos en la comunidad.
Área de la Ciencia:
- Psiquiatría; Medicina Interna; Farmacología
Sus antecedentes:
- La polidipsia psicógena es una complicación rara en pacientes con esquizofrenia paranoide. Las estrategias de tratamiento efectivas para la polidipsia psicógena siguen siendo limitadas. El manejo generalmente implica restricción de líquidos y terapia conductual.
Objetivo del estudio:
- Informar un caso de polidipsia psicógena en un paciente con esquizofrenia paranoide. Explorar opciones de tratamiento novedosas para controlar los comportamientos de ingesta compulsiva de líquidos asociados con esta condición.
Principales métodos:
- Se realizó una revisión exhaustiva del historial médico del paciente. Se obtuvieron consultas multidisciplinarias para compilar el reporte de caso. Se inició una prueba de naltrexona (25 mg) para abordar la ingesta compulsiva de líquidos.
Principales resultados:
- El paciente presentó hiponatremia crónica, una complicación de la polidipsia psicógena. Los ajustes de medicación incluyeron la interrupción de la duloxetina y la reducción de la dosis de olanzapina. La prueba de naltrexona demostró una reducción en el comportamiento de ingesta de líquidos del paciente.
Conclusiones:
- La naltrexona muestra promesa en la reducción de los comportamientos de ingesta compulsiva de líquidos. Este caso resalta un posible papel terapéutico para la naltrexona en el manejo de la polidipsia psicógena en la esquizofrenia.

01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
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...
01:12Type I Diabetes I: Introduction
Type 1 diabetes mellitus is a chronic metabolic disorder characterized by an absolute deficiency of insulin resulting from the autoimmune destruction of pancreatic β-cells. Although it can occur at any age, it is most commonly diagnosed in childhood, adolescence, or early adulthood. The loss of insulin production impairs cellular glucose uptake, resulting in persistent hyperglycemia and necessitating lifelong insulin therapy.Autoimmune Destruction of β-CellsThe hallmark of type 1 diabetes is an...
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...
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
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...
