Hormonas no anticonceptivas y artritis reumatoide en mujeres perimenopáusicas y posmenopáusicas
JAMA
|March 14, 1986
Resumen
El uso de hormonas no anticonceptivas, incluidos los anticonceptivos orales, se asoció con un riesgo reducido de desarrollar artritis reumatoide en mujeres perimenopáusicas y posmenopáusicas. Este efecto protector se confirmó en un estudio que comparó a mujeres con artritis reumatoide con aquellas con otras afecciones reumáticas.
Área de la Ciencia:
- Reumatología Reumatología.
- Endocrinología Endocrinología.
- Epidemiología La epidemiología.
Sus antecedentes:
- La artritis reumatoide (AR) es una enfermedad autoinmune crónica que afecta a las articulaciones.
- El papel de los factores hormonales, en particular las hormonas no anticonceptivas, en el desarrollo de la AR no se entiende completamente.
- Las mujeres perimenopáusicas y posmenopáusicas representan un grupo demográfico clave para estudiar las influencias hormonales en las enfermedades crónicas.
Objetivo del estudio:
- Investigar la asociación entre el uso no anticonceptivo de hormonas y la aparición de la artritis reumatoide.
- Para comparar el uso de hormonas en mujeres con AR frente a aquellas con otras afecciones reumatológicas.
- Confirmar el efecto protector potencial de los anticonceptivos orales contra el desarrollo de AR.
Principales métodos:
- Un estudio de caso-control que comparó a 490 mujeres con artritis reumatoide con 659 controles con trastornos reumatológicos de los tejidos blandos y/o osteoartritis.
- Las participantes fueron mujeres perimenopáusicas y posmenopáusicas seleccionadas al azar entre las asistentes a clínicas de reumatología.
- Se realizaron análisis univariados y multivariados para controlar las variables de confusión.
Principales resultados:
- Se observó una asociación negativa significativa entre el uso previo de hormonas no anticonceptivas y el desarrollo de artritis reumatoide (odds ratio, 0.32; 95% CI, 0.16-0.64).
- Esta asociación se mantuvo significativa después de ajustar por posibles factores de confusión.
- El análisis de subgrupos confirmó un efecto protector del uso de anticonceptivos orales en la aparición de AR.
Conclusiones:
- El uso previo de hormonas no anticonceptivas, incluidos los anticonceptivos orales, se asocia con un riesgo reducido de desarrollar artritis reumatoide.
- Las terapias hormonales pueden desempeñar un papel protector en la patogénesis de la artritis reumatoide.
- Se justifica una mayor investigación sobre los mecanismos subyacentes a esta protección hormonal.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:22Hormonal Regulation of the Menstrual Cycle
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

01:28Menopause
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
01:27Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.

01:21Rheumatic Heart Disease III: Medical Management
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...
