ABSTRACT

El sueño es una necesidad biológica. Regula las funciones inmunitarias. Las funciones inmunológicas dependen de los ritmos circadianos y del sueño regular. Según estudios previos a la pandemia, la corta duración del sueño o privación de sueño, en la semana cercana a la vacunación, se asocia con respuestas más bajas de anticuerpos. La privación de sueño da como resultado una función inmunológica más deficiente (es decir, actividad reducida de las células natural killer, producción de IL-2 suprimida) así como un aumento de los niveles circulantes de marcadores inflamatorios (IL-6, TNF-α [factor de necrosis tumoral] y proteína C reactiva). Los médicos deben ser conscientes de que muchas enfermedades que mencionamos en esta resumida actualización son comórbidas con alteraciones del sueño, y es importante, por ello, enseñar a los pacientes a mejorar su comportamiento con respecto al sueño y fomentar la educación sobre higiene del sueño. Destacamos que, en el interrogatorio de cualquier especialidad médica, deben incorporarse preguntas sobre el "dormir", dado que el sueño de buena calidad es fundamental en la prevención y el tratamiento de diversas enfermedades.

Sleep is a biological necessity. Regulates immune functions. Immune functions depend on circadian rhythms and regular sleep. According to studies prior to the pandemic, short duration of sleep or sleep deprivation, in the week leading up to vaccination, is associated with lower antibody responses to vaccination. Sleep deprivation results in poorer immune function (i.e., reduced natural killer cell activity, suppressed IL-2 production) as well as increased circulating levels of inflammatory markers (IL-6, factor of tumor necrosis, C-reactive protein). Clinicians should be aware that many illnesses, which we mention in this brief update, are comorbid with sleep disturbances and it is therefore important to teach patients to improve their sleep behavior and should encourage sleep hygiene education . We emphasize that in the questioning of any medical specialty, questions about "sleep" should be incorporated, given that good quality sleep is essential in the prevention and treatment of various diseases.

ABSTRACT

Se cree que los ancianos necesitan dormir menos. Sin embargo, no es la necesidad de sueño sino la capacidad de dormir lo que disminuye con la edad, en paralelo a la mayor prevalencia de enfermedades cardiovasculares o metabólicas, o de depresión. Poco se ha descripto sobre los hallazgos polisomnográficos de esta población. En el presente estudio analizamos los hallazgos polisomnográficos en pacientes mayores de 65 años. Se realizó un estudio descriptivo a partir del análisis de una base de datos de 551 pacientes mayores de 65 años evaluados entre junio de 2013 y diciembre de 2014. Todos los sujetos se realizaron una polisomnografía (PSG) nocturna de 6 horas de duración. Las variables analizadas fueron: latencia de sueño (LS), eficacia de sueño (ES), latencia de fase REM (Lat R), % de R, índice de apneas hipopneas (IHA) y movimientos periódicos de piernas durante el sueño (PLMS). Se dividió la población en 3 grupos: G1: de 65 a 70 años; G2: 71 a 75; G3: mayor de 75 años. Se analizaron los datos de la serie general y las diferencias intergrupos. El IHA se incrementó con la edad y resultó más severo en los pacientes mayores de 75 años en relación con el grupo de menor edad. El incremento del IAH no se asoció a un incremento del índice de masa corporal ni a mayor somnolencia diurna. (AU)


It is believed that the elderly need less sleep. However, it is not the need for sleep but the ability to sleep that decreases with age, in parallel to the increasing prevalence of cardiovascular or metabolic disease, or depression. Little has been described about the polysomnographic findings of this population, hypothesizing that there are several alterations that prematurely corrected could improve the quality of life as the years go by. We analyzed the polysomnographic findings in patients over 65 years of age. A descriptive study was carried out based on the analyses of a database of 551 patients over 65 years of age evaluated between June 2013 to December 2014. All subjects underwent nocturnal PSG of 6 hours duration. The polysomnographic variables analyzed were: sleep latency (LS), sleep efficiency (ES), latency R phase (Lat R), % R, Apneas Hypoapneas Index (AHI) and Periodic Limb Movements of Sleep (PLMS). The population was divided into 3 groups: G1: from 65 to 70 years G2: 71 to 75, G3 greater than 75. AHI increased with age, being more severe in patients over 75 years of age in relation to the younger age group. The increase in AHI was not associated with an increase in Body Mass Index (BMI) or greater daytime sleepiness. (AU)

ABSTRACT

El zolpidem es una droga hipnótica utilizada para el tratamiento del insomnio. Disminuye la latencia del sueño, el número total de despertares y aumenta el tiempo total del sueño respetando en general su arquitectura. Se cree que aumenta la fase 3 del sueño lento profundo. Nuestro objetivo es comunicar 8 casos de síndrome de ingesta nocturna relacionado al sueño y conductas automáticas complejas asociadas a sonambulismo como efecto colateral del zolpidem. Se analizaron las historias clínicas de 8 pacientes tratados con zolpidem que referían ingesta nocturna de alimentos con amnesia total o parcial del episodio. Se presentan 6 mujeres y 2 hombres, entre 32 y 72 años (media: 58 años), 7 tratados con zolpidem 10 mg/noche y 1 con zolpidem 12.5 mg/noche de liberación prolongada. El tiempo de exposición previo al desarrollo de eventos fue de 1 a 180 días (media de 39.8). El número de episodios relatados era de 1 a 8/noche (media 2.5) asociado con amnesia. Los episodios desaparecieron por completo en el 100% de los casos al suspender la medicación. El síndrome de ingesta nocturna relacionado al sueño es una parasomnia de sueño lento profundo que consiste en episodios de ingesta de alimento o bebida durante la noche, con amnesia parcial o completa del episodio. El zolpidem podría inducir el síndrome de ingesta nocturna relacionado al sueño en aproximadamente el 1% de pacientes, aunque creemos que es un efecto adverso que está subdiagnosticado. Se resuelve simplemente suspendiendo la medicación.


Zolpidem is a hypnotic drug used in sleep disorders. It binds selectively to alpha 1 subunit of the GABA A benzodiazepine receptor. Zolpidem reduces sleep latency, number of arousals and increases the total time of sleep. However, it is considered that it may increase phase 3 of non rapid eye movement sleep, where somnambulism can take place. Our aim is to report 8 cases of sleep related eating disorders associated with the use of this drug. We have evaluated the medical history of 8 patients who had received zolpidem for sleeping disorders and who have presented sleep related eating disorders. Eight patients (6 women, 2 men) aged between 32 to 72 years old, which received 10 mg of zolpidem/night except 1 that received 12.5 mg, were presented. They have referred strange eating behavior compatible to sleep related eating disorder. Symptoms appeared at a mean of 39.8 days after starting the medication. The numbers of nocturnal episodes recorded by the family or by the patient were 1 to 8 episodes of nocturnal eating per night. The morning after, patients found leftovers from the night before which they did not recall to have eaten. The remission was complete after discontinuing zolpidem. Zolpidem may induce sleep related eating disorder in about 1% of patients, although we consider there may be a subdiagnosis of this phenomenon. It will be important to bear in mind and look for this side effect because all the episodes could easily be controlled by withdrawing the drug.

ABSTRACT

A matter of interest is still knowing the disease in carriers of HVC among relatives. We studied 270 relatives of carriers of HVC. In only 3 cases the serology was (+). We did not found differences between our results and what was published. This could mean that the differences were not due only too transfusional transmission and could exist others possibilities.
