Retrospective Analysis of Fibromyalgia: Exploring the Interplay Between Various Triggers and Fibromyalgia's Severity.

OBJECTIVES: This study aimed to explore the diverse etiological factors associated with fibromyalgia (FM), including trauma, stress, infections, and head injuries, and investigate their potential correlation with FM severeness manifestation, aiming to discern FM subgroups. METHODS: The study was a retrospective analysis, conducted with data of 182 FM patients. Each patient's medical history was analyzed to identify a primary etiological event preceding FM. Following this, correlations were examined between each etiology group and different measurements, such as the impact of FM on overall function, widespread pain, depression, anxiety, and cognitive impairments. Cluster analysis was conducted to distinguish between groups of symptoms and functioning. RESULTS: Contrary to the initial hypothesis, no direct association between a specific trigger and symptom manifestation was identified. However, cluster analyses revealed 2 distinct profiles based on symptom severity. Emotional trauma emerged as a potential contributor to heightened symptom severity, impacting overall function and cognitive abilities. DISCUSSION: Emotional trauma and stress are crucial factors exacerbating FM symptoms, highlighting the importance of managing these elements in FM patients. This study underscores the complexity of FM, necessitating a nuanced understanding of its etiology and symptomatology. We recommend a multidisciplinary treatment approach that includes assessing and addressing chronic stress and trauma and incorporating stress management interventions to improve patient outcomes.

Hyperbaric oxygen therapy vs. pharmacological intervention in adults with fibromyalgia related to childhood sexual abuse: prospective, randomized clinical trial.

Fibromyalgia syndrome (FMS) is a chronic pain syndrome characterized by disruptions in pain processing within the central nervous system. It exhibits a high prevalence among patients with a history of traumatic experiences, notably childhood sexual abuse (CSA). This study compared the efficacy of hyperbaric oxygen therapy (HBOT) to the current pharmacological standard of care for individuals suffering from CSA-related FMS. Forty-eight participants diagnosed with FMS and a history of CSA were randomly assigned to either the HBOT group (60 sessions of 100% oxygen at 2 ATA for 90 min, with air breaks every 5 min) or the medication (MED) group (FDA-approved medications, Pregabalin and Duloxetine). The primary endpoint was the Fibromyalgia impact questionnaire (FIQ) score, while secondary endpoints encompassed emotional status and daily functioning questionnaires, as well as pain thresholds and conditioned pain modulation tests. Brain activity was evaluated through single photon emission computed tomography (SPECT). Results revealed a significant group-by-time interaction for the FIQ score favoring HBOT over MED (p < 0.001), with a large effect size (Cohen's d = - 1.27). Similar findings were observed in emotional symptoms and functional measures. SPECT imaging demonstrated an increase in activity in pre-frontal and temporal brain areas, which correlated with symptoms improvement. In conclusion, HBOT exhibited superior benefits over medications in terms of physical, functional, and emotional improvements among FMS patients with a history of CSA. This associated with increased activity in pre-frontal and temporal brain areas, highlighting the neuroplasticity effect of HBOT.

The use of hyperbaric oxygen for veterans with PTSD: basic physiology and current available clinical data.

Post-traumatic stress disorder (PTSD) affects up to 30% of veterans returning from the combat zone. Unfortunately, a substantial proportion of them do not remit with the current available treatments and thus continue to experience long-term social, behavioral, and occupational dysfunction. Accumulating data implies that the long-standing unremitting symptoms are related to changes in brain activity and structure, mainly disruption in the frontolimbic circuit. Hence, repair of brain structure and restoration of function could be a potential aim of effective treatment. Hyperbaric oxygen therapy (HBOT) has been effective in treating disruptions of brain structure and functions such as stroke, traumatic brain injury, and fibromyalgia even years after the acute insult. These favorable HBOT brain effects may be related to recent protocols that emphasize frequent fluctuations in oxygen concentrations, which in turn contribute to gene expression alterations and metabolic changes that induce neuronal stem cell proliferation, mitochondrial multiplication, angiogenesis, and regulation of the inflammatory cascade. Recently, clinical findings have also demonstrated the beneficial effect of HBOT on veterans with treatment-resistant PTSD. Moderation of intrusive symptoms, avoidance, mood and cognitive symptoms, and hyperarousal were correlated with improved brain function and with diffusion tensor imaging-defined structural changes. This article reviews the current data on the regenerative biological effects of HBOT, and the ongoing research of its use for veterans with PTSD.
