The association between borderline personality disorder, fibromyalgia and chronic fatigue syndrome: systematic review

Lacticaseibacillus rhamnosus Strains for Alleviation of Irritable Bowel Disease and Chronic Fatigue Syndrome

Lacticaseibacillus rhamnosus is applied as a probiotic to alleviate various metabolic, gastrointestinal, and psychological symptoms and diseases, and its probiotic effectiveness is strain-specific. In this study, we obtained 21 strains of Ls. rhamnosus, and their genomes were sequenced. We defined the pan- and core-genomes of Ls. rhamnosus. Phenotypes such as the assimilation of carbohydrates and antibiotic resistance were experimentally characterized and associated with genome annotations. Nine strains were selected and tested for growth rates, tolerance to acidity/alkalinity and bile acids, the production of short-chain fatty acids, and competition with pathogenic microbes. Strains WL11 and WL17 were targeted as potential probiotics and were applied in mouse model tests for the alleviation of chronic fatigue syndrome (CFS) and irritable bowel syndrome (IBS). The results showed that WL11 and WL17 effectively alleviated slow body weight gain, anxiety, poor memory, and cognitive impairment in CFS mouse models. They also reduced the expression of pro-inflammatory factors, such as TNF-α and IL-6, and alleviated intestinal peristalsis, visceral hypersensitivity, and anxiety-like behavior in IBS mouse models. This study reports new Ls. rhamnosus strain resources and their effect on alleviation of both IBS and CFS symptoms with mouse models; the probiotic functions of those strains in human patients remain to be further tested.

Psychosomatic Approach to Fibromyalgia Syndrome: Concept, Diagnosis and Treatment

Fibromyalgia syndrome (FMS) has chronic widespread pain (CWP) as a core symptom and a variety of associated somatic and psychological symptoms such as fatigue, sleep problems, cognitive disturbances, multiple somatic pain, and depression. FMS is the subject of considerable controversy in the realm of nosology, diagnosis, pathophysiology, and treatment.Moreover, the fact that FMS and mental illness are closely associated with each other might intensify the confusion for the distinction between FMS and mental disorders. This narrative literature review aims to provide the concept, diagnosis, and treatment of FMS from the integrative biopsychosocial and psychosomatic perspective. This article first explains the concepts of FMS as a disease entity of biopsychosocial model, and then summarizes the changes of diagnostic criteria over past three decades, differential diagnosis and comorbidity issue focused on mental illnesses. In addition, an overview of treatment of FMS is presented mainly by arranging the recommendations from the international guidelines which have been developed by four official academic associations.

The Effect of Multiprobiotics on Memory and Attention in Fibromyalgia: A Pilot Randomized Controlled Trial

Fibromyalgia syndrome (FMS) is a chronic, generalized and diffuse pain disorder accompanied by cognitive deficits such as forgetfulness, concentration difficulties, loss of vocabulary and mental slowness, among others. In recent years, FMS has been associated with altered intestinal microbiota, suggesting that modulating gut microbiota (for example, through probiotics) could be an effective therapeutic treatment. Thus, the aim of the present study was to continue exploring the role of probiotics in cognitive processes in patients with FMS. A pilot randomized controlled trial was conducted in 31 patients diagnosed with FMS to compare the effects of a multispecies probiotic versus a placebo on cognitive variables (memory and attention) after eight weeks. Results showed that treatment with a multispecies probiotic produced an improvement in attention by reducing errors on an attention task, but it had no effect on memory. More specifically, a tendency to reduce errors of omission (Go trials) during the Go/No-Go Task was observed after treatment. These findings, along with our previous results in impulsivity, underline the relevance of using probiotics as a therapeutic option in FMS, although more research with a larger sample size is required.

Mitochondria and immunity in chronic fatigue syndrome

It is widely accepted that the pathophysiology and treatment of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) could be considerably improved. The heterogeneity of ME/CFS and the confusion over its classification have undoubtedly contributed to this, although this would seem a consequence of the complexity of the array of ME/CFS presentations and high levels of diverse comorbidities. This article reviews the biological underpinnings of ME/CFS presentations, including the interacting roles of the gut microbiome/permeability, endogenous opioidergic system, immune cell mitochondria, autonomic nervous system, microRNA-155, viral infection/re-awakening and leptin as well as melatonin and the circadian rhythm. This details not only relevant pathophysiological processes and treatment options, but also highlights future research directions. Due to the complexity of interacting systems in ME/CFS pathophysiology, clarification as to its biological underpinnings is likely to considerably contribute to the understanding and treatment of other complex and poorly managed conditions, including fibromyalgia, depression, migraine, and dementia. The gut and immune cell mitochondria are proposed to be two important hubs that interact with the circadian rhythm in driving ME/CFS pathophysiology.

Exploring the links among borderline personality disorder symptoms, trauma, and pain in patients with chronic pain disorders

OBJECTIVE

Chronic pain and borderline personality disorder (BPD) are commonly comorbid and jointly associated with increased symptoms of both disorders and clinical and functional impairment. Little is known, however, about specific links between these disorders. In a cross-sectional study of patients with chronic pain, we compared participants high or low on BPD symptoms on patterns of pain experience and types of child and adult traumas.

METHODS

Adults (N = 181) with chronic pain completed self-reports of pain severity, dimensions of pain experiencing, body coverage of pain, and clinical indicators of central sensitization (i.e., chronic hypersensitivity of the central nervous system), as well as measures of child and adult physical abuse, sexual abuse, trauma, and neglect. Participants also completed the McLean Screening Instrument for BPD.

RESULTS

Participants with clinically significant BPD symptoms (n = 32) reported more childhood sexual trauma, punishment, and neglect, as well as adult physical/sexual trauma, than those without elevated BPD symptoms. Among participants with clinically significant BPD symptoms, affective pain and central sensitization were elevated, potentially explained by heightened negative affect in BPD.

CONCLUSION

BPD symptoms are associated with increased clinical severity among patients with chronic pain as well as a unique manifestation of pain experiencing (i.e., increased affective pain and central sensitization in particular). Childhood trauma of all types is associated with chronic pain and BPD co-occurrence. Researchers and clinicians should assess for BPD in people with chronic pain to enhance conceptual models of the transaction between these disorders and to improve clinical care.

Personality Traits in Fibromyalgia (FM): Does FM Personality Exists? A Systematic Review

Introduction:

Fibromyalgia (FM) is the second most common rheumatic disease with many effects on patient's quality of life. It has been described as a chronic condition characterized by widespread musculo-skeletal pain, sleep disorders and prominent fatigue. Regarding the role of personality factors in fibromyalgia, researchers have focused both on personality traits and psychopathological aspects showing inconsistent results. In particular, several studies have examined the role of alexithymia in FM patients, a trait of personality characterized by difficulty in identification, recognition and description of emotions and feelings, while others have focused on a specific type of personality, such as type D personality (distressed personality). Other studies investigated personality in FM patients referring to Cloninger’s model, a psychobiological model of personality that includes both temperamental and character dimensions of personality. Analyzing scientific literature on this subject seems well suited to provide a critical review of the latest studies and their results.

Methods:

The method used for this review satisfies the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). We identified PsycInfo and PubMed as databases for our research.

Results:

Personality is studied under many aspects and a reference model is not always present. Many studies underline high levels of alexithymia and type D personality in FM patients but when depression is controlled, these results do not differ from those of healthy controls.

Conclusion:

Studies that use a comprehensive model of personality present a different theoretical approach and use alternatively the Big-Five model, Eysenck’s and Cloninger’s models. The use of a comprehensive model of personality and the control of psychopathological disorders, such as anxiety and depression, seem to be very relevant for a better understanding of a specific personality profile associated with fibromyalgia.

School Nurses Can Improve the Lives of Students With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic illness that is defined and diagnosed by its symptoms: extreme fatigue made worse by physical and mental activity, pain and decreased mental stamina, among others. A long-held, erroneous belief that ME/CFS is not a physiological illness has persisted among some clinicians, leading to the denial of a patient's physical illness and attributing the symptoms to other causes. The debilitating effects of ME/CFS in the pediatric population can affect all aspects of academic, social, emotional, and physical development. ME/CFS has been diagnosed in children younger than 10 years. Therefore, the school nurse is likely to encounter one or more students in the various stages of this disease, putting the school nurse in a position to ameliorate the impact of this potentially devastating chronic condition.

The complexities of fibromyalgia and its comorbidities

PURPOSE OF REVIEW

Fibromyalgia syndrome (FMS) is defined as chronic, widespread musculoskeletal pain and tenderness with concomitant mood and cognitive dysfunction. Several comorbidities have been reported to be associated with FMS. We reviewed the literature concerning the most noteworthy chronic conditions associated with FMS.

RECENT FINDINGS

There is mounting evidence displaying the concurrence of fibromyalgia and coexisting medical and psychiatric conditions. Such comorbidities may blur the classical clinical presentations and erroneously lead to misinterpretation of disease activity. The recognition of this fact should be underlined, as misrecognition may lead to excessive therapy and avoidable side-effects of medications on the one hand and to a better handling of FMS on the other hand, leading to improved clinical outcomes.

SUMMARY

A greater proportion of psychiatric and rheumatologic disorders are associated with FMS patients than the population. Consequently, physicians treating patients with either condition should keep in mind that these patients may have such comorbidities and should be treated accordingly.

Are probiotic treatments useful on fibromyalgia syndrome or chronic fatigue syndrome patients? A systematic review

Evidence suggests that the gut microbiota might play an important role in fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS). Our goal is to systematically review the reported effect of probiotic treatments in patients diagnosed with FMS or CFS. A systematic review was carried out using 14 databases (PubMed, Cochrane Library, Scopus, PsycINFO, and others) in February 2016 to search for randomised controlled trials (RCTs) and pilot studies of CFS or FMS patient, published in the last ten years (from 2006 to 2016). The Jadad scale was used to asseverate the quality of the clinical trials considered. Two studies (n=83) met the inclusion criteria, which were performed in CFS patients and both studies were considered as a 'High range of quality score'. The administration of Lactobacillus casei strain Shirota in CFS patients, over the course of 8 weeks, reduced anxiety scores. Likewise, this probiotic changed the faecal composition following 8 weeks of treatment. Additionally, the treatment with Bifidobacterium infantis 35624 in CFS patients, during the same period, reduced inflammatory biomarkers. The evidence about the usefulness of probiotics in CFS and FMS patients remains limited. The studied strains of probiotics have demonstrated a significant effect on modulating the anxiety and inflammatory processes in CFS patients. However, more experimental research, focusing mainly on the symptoms of the pathologies studied, is needed.

Burnout, Depression, and Borderline Personality: A 1,163-Participant Study

We examined the association of burnout with borderline personality (BP) traits in a study of 1,163 educational staff (80.9% women; mean age: 42.96). Because burnout has been found to overlap with depression, parallel analyses of burnout and depression were conducted. Burnout symptoms were assessed with the Shirom-Melamed Burnout Measure, depressive symptoms with the PHQ-9, and BP traits with the Borderline Personality Questionnaire. Burnout was found to be associated with BP traits, controlling for neuroticism and history of depressive disorders. In women, burnout was linked to both the "affective insecurity" and the "impulsiveness" component of BP. In men, only the link between burnout and "affective insecurity" reached statistical significance. Compared to participants with "low" BP scores, participants with "high" BP scores reported more burnout symptoms, depressive symptoms, neuroticism, and occupational stress and less satisfaction with life. Disattenuated correlations between burnout and depression were close to 1, among both women (0.91) and men (0.94). The patterns of association of burnout and depression with the main study variables were similar, pointing to overlapping nomological networks. Burnout symptoms were only partly attributed to work by our participants. Our findings suggest that burnout is associated with BP traits through burnout-depression overlap.

Are Traditional Remedies Useful in Management of Fibromyalgia and Chronic Fatigue Syndrome? A Review Study

Fibromyalgia and chronic fatigue syndrome are disorders that often occur simultaneously and are characterized by widespread pain and persistent fatigue. The patients are associated with disability and impairment social and physical functions. There are many remedies in traditional Persian medicine suggested for management of the disease complaints. The aim of this study was to investigate the clinical presentations and pathophysiology of disorders with the basic and principal textbook of traditional Persian medicine written by Avicenna (Canon of Medicine). According to Persian medicine, the term E’aya can be matched by mentioned disorders. Avicenna believed that strenuous activities play an important role in the beginning of some types of fatigue. He classified fatigue into 4 groups, and in each type the clinical symptoms varied. The multifaceted entity of fibromyalgia and chronic fatigue syndrome in Persian medicine and conventional medicine suggests multidisciplinary therapies in management of these disabling disorders.
