[From neurasthenia to post-exertion disease: Evolution of the diagnostic criteria of chronic fatigue syndrome/myalgic encephalomyelitis]. / De la neurastenia a la enfermedad postesfuerzo: evolución de los criterios diagnósticos del síndrome de fatiga crónica/encefalomielitis miálgica.

Changes in the terminology and diagnostic criteria for chronic fatigue syndrome/myalgic encephalomyelitis are explained in this paper. This syndrome is a complex and controversial entity of unknown origins. It appears in the medical literature in 1988, although clinical pictures of chronic idiopathic fatigue have been identified since the nineteenth century with different names, from neurasthenia, epidemic neuromyasthenia, and benign myalgic encephalomyelitis up to the current proposal of disease of intolerance to effort (post-effort). All of them allude to a chronic state of generalised fatigue of unknown origin, with limitations to physical and mental effort, accompanied by a set of symptoms that compromise diverse organic systems. The International Classification of Diseases (ICD-10) places this syndrome in the section on neurological disorders (G93.3), although histopathological findings have not yet been found to clarify it. Multiple organic alterations have been documented, but a common biology that clarifies the mechanisms underlying this disease has not been established. It is defined as a neuro-immune-endocrine dysfunction, with an exclusively clinical diagnosis and by exclusion. Several authors have proposed to include CFS/ME within central sensitivity syndromes, alluding to central sensitisation as the common pathophysiological substrate for this, and other syndromes. The role of the family doctor is a key figure in the disease, from the detection of those patients who present a fatigue of unknown nature that is continuous or intermittent for more than 6 months, in order to make an early diagnosis and establish a plan of action against a chronic disease with high levels of morbidity in the physical and mental sphere. OBJECTIVE: To carry out a bibliographic review of the terminology and diagnostic criteria of the chronic fatigue syndrome/myalgic encephalomyelitis, in order to clarify the pathology conceptually, as a usefulness in the diagnosis of Primary Care physicians.

High prevalence of asymptomatic carriers of Tropheryma whipplei in different populations from the North of Spain.

INTRODUCTION: Tropheryma whipplei is the causative agent of Whipple disease. T. whipplei has also been detected in asymptomatic carriers with a very different prevalence. To date, in Spain, there are no data regarding the prevalence of T. whipplei in a healthy population or in HIV-positive patients, or in chronic fatigue syndrome (CFS). Therefore, the aim of this work was to assess the prevalence of T. whipplei in stools in those populations. METHODS: Stools from 21 HIV-negative subjects, 65 HIV-infected, and 12 CFS patients were analysed using real time-PCR. HIV-negative and positive subjects were divided into two groups, depending on the presence/absence of metabolic syndrome (MS). Positive samples were sequenced. RESULTS: The prevalence of T. whipplei was 25.51% in 98 stool samples analysed. Prevalence in HIV-positive patients was significantly higher than in HIV-negative (33.8% vs. 9.09%, p=0.008). Prevalence in the control group with no associated diseases was 20%, whereas no positive samples were observed in HIV-negative patients with MS, or in those diagnosed with CFS. The prevalence observed in HIV-positive patients without MS was 30.35%, and with MS it was 55.5%. The number of positive samples varies depending on the primers used, although no statistically significant differences were observed. CONCLUSIONS: There is a high prevalence of asymptomatic carriers of T. whipplei among healthy and in HIV-infected people from Spain. The role of T. whipplei in HIV patients with MS is unclear, but the prevalence is higher than in other populations.

[Exercise prescription in post-COVID syndrome: A challenge for primary healthcare]. / Prescripción de ejercicio en condición pos-COVID. Un reto en Atención Primaria.

After the SARS-CoV-2 pandemic we face a new global epidemic: the Post-COVID Syndrome. This novel condition has fluctuating progression and a wide range of symptoms, such as fatigue, headaches, muscle pain or breathlessness. Although its pathophysiology is not clear, a multiorganic affection is suspected, altering the immune, cardiorespitatory and nervous systems. Whereas there is no consensus over its treatment, most of the researches conclude the effectiveness of therapeutic exercise and a multicomponent rehabilitation, coordinating and cooperating between different health professionals. A functional, respiratory and strength evaluation prior to treatment prescription is highly recommended, since it will help professionals to precisely prescribe and objectively measure the evolution of our patients. In this article we suggest a few tests, adequate to primary health requirements, to evaluate our patients' initial condition, as well as the most secure way to initiate a therapeutic exercise programme, together with other healthcare providers.

[Long COVID: Is it really myalgic encephalomyelitis? Bibliographic review and considerations]. / COVID persistente: ¿es en realidad una encefalomielitis miálgica? Revisión bibliográfica y consideraciones.

Clinical sequelae of a disease as widespread as COVID-19 can be of great importance for primary care due to their prevalence and the morbidity they entail. The definition of long COVID and the establishment of its temporality are various, but some authors consider possible that this syndrome is actually myalgic encephalomyelitis. Similarities are observed when comparing the International Consensus Criteria for the diagnosis of myalgic encephalomyelitis with the symptoms described for long COVID. Blood tests, pulse oximetry, chest radiography, and thoracic ultrasound are recommended in patients with persistent symptoms after acute infection. Management in both conditions consists of treating the main symptoms. The possibility that COVID-19 can lead to a chronic condition such as myalgic encephalomyelitis makes long-term follow-up of patients who have suffered from this infection essential.

[What scientific evidence do the current classifications have in order to assess occupational disability in patients with central sensitisation syndrome?] / ¿Qué evidencia científica tienen los métodos propuestos para valorar la discapacidad laboral de los pacientes con síndrome de sensibilización central?

Central sensitisation syndrome includes disorders such as fibromyalgia, chronic fatigue syndrome, multiple chemical sensitivity, and electromagnetic sensitivity syndrome. These disorders have been acquiring both medical and social relevance due to the increase in prevalence, the absence of a curative treatment, the limitations they cause, and the high healthcare costs they involve. Furthermore, all of them share an unknown aetiology and the absence of objective parameters to establish their diagnosis and severity. Multiple methods and classifications have been proposed to graduate the disability of these patients, but currently none of them have obtained sufficient evidence.

HPV vaccination syndrome: A clinical mirage, or a new tragic fibromyalgia model. / Síndrome posvacunal VPH. ¿Un espejismo clínico, o un nuevo modelo trágico de fibromialgia?

Independent investigators have described the onset of a chronic painful dysautonomic syndrome soon after human papillomavirus (HPV) vaccination. The veracity of this syndrome is hotly debated. Many of the reported post-HPV vaccination cases fullfill fibromyalgia diagnostic criteria. This article discusses the arguments favoring the existence of a syndrome associated to HPV vaccination. We propose that fibromyalgia dysautonomic-neuropathic model could help in the diagnostic and therapeutic process in those patients in whom the onset of a painful chronic illness began after HPV immunization. On the other hand, if its veracity is corroborated, HPV vaccination syndrome may become a new tragic fibromyalgia model.

Introducción. Una vez declarada la pandemia por COVID-19, los servicios de rehabilitación empezaron a prepararse para la atención, mediante diferentes abordajes, de los pacientes que se recuperaran de esta enfermedad. Objetivo. Correlacionar los resultados obtenidos en el Cuestionario Respiratorio de Saint George (CRSG), la Escala de Severidad de la Fatiga (FSS) y la Escala de Actividades de la Vida Diaria London Chest (LCADL) aplicados en pacientes recuperados de COVID-19 para medir su calidad de vida y la fatiga. Métodos. Estudio descriptivo retrospectivo realizado en 60 pacientes recuperados de COVID-19, moderado o grave, que ingresaron al programa de rehabilitación pulmonar de un hospital de tercer nivel de Bogotá, Colombia, entre el primero de octubre de 2020 y el 30 de junio de 2021. Se analizaron variables demográficas y para caracterizar la calidad de vida y la fatiga de los participantes se utilizó el cuestionario CRSG, la escala FSS y la escala LCADL, cuyos resultados se compararon mediante correlación de Spearman. Para el análisis estadístico se utilizó el programa de SPSS versión 28. Resultados. La fatiga está correlacionada con la calidad de vida, y al ser identificada se puede intervenir mediante los ejercicios terapéuticos de los programas de rehabilitación pulmonar, lo cual optimiza los resultados esperados. Conclusiones. Existe una adecuada correlación entre las escalas CRSG y LCADL; esto es importante porque aplicar escalas de calidad de vida en pacientes con SARS-CoV-2 permite conocer las áreas que pueden ser intervenidas mediante programas de rehabilitación pulmonar para lograr una intervención adecuada

Introduction. Once the COVID-19 pandemic was declared, rehabilitation services began to prepare for the care, through different approaches, of patients recovering from this disease. Objective. To correlate the results obtained in the Saint George's Respiratory Questionnaire (CRSG), the Fatigue Severity Scale (FSS) and the London Chest Activities of Daily Living Scale (LCADL) applied in patients recovered from COVID-19 to measure their quality of life and fatigue. Methods. Retrospective descriptive study conducted in 60 patients recovered from COVID-19, moderate or severe, who were admitted to the pulmonary rehabilitation program of a third level hospital in Bogota, Colombia, between October 1, 2020 and June 30, 2021. Demographic variables were analyzed and the CRSG questionnaire, the FSS scale and the LCADL scale were used to characterize the quality of life and fatigue of the participants, whose results were compared by Spearman correlation. SPSS version 28 was used for statistical analysis. Results. Fatigue is correlated with quality of life, and when identified, it can be intervened by means of therapeutic exercises in pulmonary rehabilitation programs, which optimizes the expected results. Conclusions. There is an adequate correlation between the CRSG and LCADL scales; this is important because applying quality of life scales in patients with SARS-CoV-2 allows us to know the areas that can be intervened through pulmonary rehabilitation programs to achieve an adequate intervention.

Síndrome Pos-COVID y Síndrome de Fatiga Crónica: ¿Dos caras de la misma moneda? / POST-COVID SYNDROME AND CHRONIC FATIGUE SYNDROME: TWO SIDES OF THE SAME COIN

El síndrome de fatiga crónica es una enfermedad caracterizada, principalmente, por la manifestación de la fatiga, el dolor muscular difuso, y alteraciones en el sueño, en un periodo de no menos de 6 meses y que no son explicables por alguna causa. Es llamativo que, luego de un periodo de tiempo de padecer la COVID-19, los pacientes presenten síntomas similares a los hallados en el síndrome de fatiga crónica. A esta afección se la denomino síndrome pos-COVID. Los virus son los principales sospechosos en la aparición de ambos síndromes, estos podrían ocasionar la generación de daño mitocondrial, una neuroinflamación, alteración en el sistema glinfático o la disfunción en el eje hipotálamo-pituitario-adrenal entre otros. Dichos mecanismos serían los implicados en la aparición de los síntomas que padecen los pacientes con estos síndromes. El objetivo de esta revisión literaria es analizar y describir los posibles mecanismos que explicarían la manifestación de los síntomas del síndrome de fatiga crónica en los pacientes que hayan sufrido la COVID-19. Hasta el momento no existen tratamientos totalmente efectivos para erradicar los síntomas en ambos síndromes. Dado el abanico de síntomas que padecen estos pacientes, el enfoque terapéutico debe ser interdisciplinario para tratar de mejorar su calidad de vida.

Gender differences in chronic fatigue syndrome.

BACKGROUND AND OBJECTIVES: Chronic fatigue syndrome (CFS) is a chronic condition that predominantly affects women. To date, there are few epidemiologic studies on CFS in men. The objective of the study was to assess whether there are gender-related differences in CFS, and to define a clinical phenotype in men. PATIENTS AND METHODS: A prospective, cross-sectional cohort study was conducted including CFS patients at the time of diagnosis. Sociodemographic data, clinical variables, comorbid phenomena, fatigue, pain, anxiety/depression, and health quality of life, were assessed in the CFS population. A comparative study was also conducted between genders. RESULTS: The study included 1309 CFS patients, of which 119 (9.1%) were men. The mean age and symptoms onset were lower in men than women. The subjects included 30% single men vs. 15% single women, and 32% of men had specialist work vs. 20% of women. The most common triggering factor was an infection. Widespread pain, muscle spasms, dizziness, sexual dysfunction, Raynaud's phenomenon, morning stiffness, migratory arthralgias, drug and metals allergy, and facial oedema were less frequent in men. Fibromyalgia was present in 29% of men vs. 58% in women. The scores on physical function, physical role, and overall physical health of the SF-36 were higher in men. The sensory and affective dimensions of pain were lower in men. CONCLUSIONS: The clinical phenotype of the men with CFS was young, single, skilled worker, and infection as the main triggering agent. Men had less pain and less muscle and immune symptoms, fewer comorbid phenomena, and a better quality of life.

Chronic fatigue syndrome and sleep disorders: clinical associations and diagnostic difficulties. / Síndrome de fatiga crónica y los trastornos del sueño: relaciones clínicas y dificultades diagnósticas.

INTRODUCTION: Chronic fatigue syndrome (CFS) is characterised by the presence of intractable fatigue and non-restorative sleep, symptoms which are also very prevalent in multiple diseases and appear as side effects of different drugs. Numerous studies have shown a high prevalence of sleep disorders in patients with CFS. However, non-restorative sleep and fatigue are frequently symptoms of the sleep disorders themselves, so primary sleep disorders have to be ruled out in many cases of CFS. DEVELOPMENT: This review was performed using a structured search of the MeSH terms ([Sleep]+[Chronic fatigue syndrome]) in the PubMed database. CONCLUSION: Identifying primary sleep disorders in patients meeting diagnostic criteria for CFS will allow for a more comprehensive treatment approach involving new diagnostic and therapeutic strategies that may improve quality of life for these patients.

Los trastornos neuropsiquiátricos más frecuentes fueron depresión (85,7%), migraña (35%) y ansiedad (14,7%). Los fármacos más utilizados fueron los inhibidores de la recaptación de serotonina y duales, acetaminofén y gabaérgicos. Manejo con terapias complementarias e intervención psicológica se observaron en baja proporción. Conclusiones: La fibromialgia y las enfermedades neuropsiquiátricas son patologías que coexisten con frecuencia; la presentación sociodemográfica y clínica es similar a lo descrito en la literatura, sin embargo, la presencia de depresión en esta población fue mayor. Un enfoque terapéutico transdisciplinario, favorecería la calidad de vida de los pacientes y el curso de la enfermedad.

ABSTRACT Introduction: Fibromyalgia is a common cause of chronic pain in the world, with a prevalence of 0.2% to 6.4% in the general population. These patients are more likely to have neuropsychiatric disorders. The objective of this study was to describe the sociodemographic and clinical profile of patients with fibromyalgia and neuropsychiatric comorbidity. Methods: A cross-sectional, descriptive study was conducted in which Information was collected from the medical records of patients with fibromyalgia and neuropsychiatric comorbidity, from specialist institution in Antioquia, during the years 2010 to 2016. Descriptive statistics tools were applied. Results: Of the 1,106 medical records with a confirmed diagnosis of fibromyalgia, 497 had neuropsychiatric comorbidity. The median age was 54 years (IQR 15), and the majority were women, residing in an urban area, and were married or living with their partner. Low-medium socioeconomic status and basic-medium educational level were the most reported. The most frequent symptoms were sleep disturbances (70.6%), myalgia (66.4%), and chronic fatigue (55.9%). The most frequent neuropsychiatric disorders were depression (85.7%), migraine (35%), and anxiety (14.7%). The most commonly used drugs were serotonin and dual reuptake inhibitors, acetaminophen, and GABAergic drugs. A low percentage was managed with complementary therapies and psychological intervention. Conclusions: Fibromyalgia and neuropsychiatric diseases are diseases that frequently coexist. Although the sociodemographic and clinical presentation is as described in the literature, the presence of depression was greater in this population. A multidisciplinary therapeutic approach would favour the quality of life of the patients and the course of the disease.

Abstract Objective: To establish the effect of therapeutic dance and physical exercise on the symptomatology and number of painful points in women with fibromyalgia. Materials and methods: Quasi-experimental study that considered a randomized probabilistic sample. A total of 37 women with fibromyalgia underwent therapeutic dance (n=18) and physical exercise (n=19) programs. The average age was 47.4 ± 8.4 years. The length of the intervention was 3 months with a training frequency of 2 sessions per week and a duration of 60 minutes per session. All the participants provided information that allowed to determine the general pain index (GPI) and the scale of symptom severity (SSS). Results: Therapeutic dance and physical exercise significantly decreased the number of painful points (from 12.1 ± 2.8 to 7.3 ± 3.1 for pre- and post-values respectively (p = 0.000)) and the symptoms associated with fibromyalgia (8.7 ± 2.3 to 5.7 ± 2.6 for pre- and post-values respectively (p = 0.000)). Conclusions: Therapeutic dance and physical exercise have an equivalent beneficial effect on the reduction of the general pain index, depression, cognitive symptoms and sleep disorders in women with fibromyalgia.

[Impact of the fibromyalgia in the chronic fatigue syndrome]. / Impacto de la fibromialgia en el síndrome de fatiga crónica.

BACKGROUND AND OBJECTIVE: Different studies have showed association of the chronic fatigue syndrome (CFS) with other pathologies, including fibromyalgia (FM). The objective of this study is to analyze whether there are differences in the clinic and in the assessment of fatigue in CFS patients associated or not with FM. PATIENTS AND METHODS: A cross-sectional, single-site observational study was undertaken on a consecutive cases of a register of CFS patients at CFS Unit in Vall d'Hebron Hospital, Barcelona, from January 2008 until March 2011. The variables analyzed were FM comorbidity, sleep and fatigue characteristics and cognitive, neurological and autonomic symptoms. Questionnaires of fatigue impact scale, fatigue strength and impact on quality of life SF-36 were evaluated. RESULTS: We included 980 CFS patients (mean age: 48±9 years; 91% women). Fibromyalgia was present in 528 patients (54%). The level of fatigue (P=.001) and pain (P<.001) was higher in FM patients. Patients with CFS and FM had more prevalence of sleep-related phenomena. The percentage of patients and the degree of severity of cognitive symptoms, neurological and autonomic dysfunction was higher in FM patients (P<.001). FM patients scored higher on the fatigue impact scale (P<.001) and showed worse results in the quality of life questionnaire (P<.001). CONCLUSIONS: FM co-morbidity worse clinical parameters, fatigue and the perception of quality of life in CFS patients.

Prevalencia del síndrome de fatiga crónica en trabajadores de una fábrica mexicana de cierres / Prevalence of the chronic fatigue syndrome in workers of a Mexican factory of zippers

Antecedentes: El síndrome de fatiga crónica (SFC) se caracteriza por cansancio persistente e inexplicado a pequeños esfuerzos tanto físicos como mentales, y suele acompañarse de un contexto sintomático tipo inflamatorio; su curso crónico y persistente ocasiona limitación funcional. Es una entidad subdiagnosticada y de etiología múltiple: puede ser infecciosa, de origen ambiental, tóxico y psicosocial; con prevalencia que oscila entre el 2,6% y el 2,8% en la población general; su frecuencia en población trabajadora ha sido muy poco explorada. Objetivo: Determinar la prevalencia del SFC en trabajadores de una fábrica de cierres del estado de Hidalgo, México. Métodos: Estudio transversal que incluyó una muestra por conveniencia no aleatoria de 137/152 (90%) trabajadores de una fábrica de cierres localizada en el estado de Hidalgo, México, y en quienes se exploraron diversas variables sociodemográficas, clínicas y laborales; para el diagnóstico de SFC se aplicaron los criterios del Centro de Control de Enfermedades (CDC) 1994. Se realizó análisis simple descriptivo con cálculo de prevalencia puntual. Resultados: En la población trabajadora estudiada se encontró una prevalencia de 19,71%, sin encontrar diferencias proporcionales de las variables estudiadas, excepto en su distribución por sexo (p<0,05) con predominio del sexo femenino. Conclusión: La prevalencia de SFC en el grupo de trabajadores estudiados fue más elevada que la referida en población general. Los resultados se apegan a la idea que el trabajo podría contribuir de manera importante al desarrollo de SFC.

Background: Chronic fatigue syndrome (CFS) is characterized by persistent fatigue and unexplained to small physical and mental effort, and usually accompanied by an inflammatory symptomatic context, its course is chronic and persistent that cause functional limitation. It is an underdiagnosed entity with multiple etiologies: it may be infectious, environmental, toxic or psychological, with prevalence that ranges between 2,6% and 2,8% in the general population, its frequency among workers has been very little explored. Objective: To determine the prevalence of CFS in workers at a zipper factory in the state of Hidalgo, Mexico. Methods: Cross-sectional study included a non random convenience sample of 137/152 (90%) workers in a factory zippers located in the state of Hidalgo, Mexico, and who were explored in several sociodemographic, clinical and labor variables; for CFS diagnose criteria of the Center for Disease Control (CDC) 1994 were applied. Simple descriptive analysis was performed to estimate punctual prevalence. Results: We determined prevalence of 19.71% in the working population studied, no differences in proportion of the studied variables, except sex distribution (p <0.05) with female predominance. Conclusion: CFS prevalence in the group of workers studied was higher than that reported in general population. Results agree with the idea that work could contribute significantly to CFS development.

Dificultades en el diagnóstico y tratamiento de la disautonomía / Difficulties in the diagnosis and dysautonomia treatment

La disautonomía es una condición médica frecuente que, por lo general, cursa sin ser diagnosticada y es causa de fatiga crónica, mareos, desmayos y mala calidad de vida. estos enfermos muchas veces peregrinan de médico en médico, se les hacen múltiples exámenes, se plantean múltiples hipótesis, pero el diagnóstico preciso no se hace, ya que no se tiene en cuenta la disautonomía. Ésta frecuentemente se asocia al Síndrome de Hiperlaxitud Articular, que es una de las alteraciones hereditarias de la fibra colágena que es muy prevalente en Chile. El tratamiento, que es muy eficaz, suele fallar, ya que los enfermos temen tomar muchos líquidos y aumentar la sal y por miedo a los mineralocorticoides.

Dysautonomia is a frequent medical condition which goes undiagnosed and produces chronic fatigue, dizziness, syncope and poor quality of life. It is usually seen in association with the Joint Hypermobility Syndrome. Patients with Dysautonomia perambulate from physician to physician, get multiple tests, are given different medical hypothesis, but the precise diagnosis is not made. Even though there is a good treatment, the results are not as good as expected, because the patients are concerned about taking too much salt and water and are afraid of mineralocorticoids.
