HRV biofeedback appears to be a useful adjunctive treatment for the treatment of MDD, associated with large acute increases in HRV and some chronic increases, suggesting increased cardiovagal activity. It is possible that regular exercise of homeostatic reflexes helps depression even when changes in baseline HRV are smaller. A randomized controlled trial is warranted.
These data suggest that HRV biofeedback may be a useful treatment for FM, perhaps mediated by autonomic changes. While HRV effects were immediate, blood pressure, baroreflex, and therapeutic effects were delayed. This is consistent with data on the relationship among stress, HPA axis activity, and brain function.
Objective. Affective balance, relative levels of negative affect (NA) and positive affect (PA), better describes emotional functioning than NA or PA alone. Affect balance styles and their relationship to clinical outcomes were compared between patients with fibromyalgia (FM) and controls. Methods. FM patients (n ؍ 79) were compared with patients with other medical conditions (controls; n ؍ 92). Patients underwent a physical examination, completed questionnaires, and were screened for clinical disorders such as depression, with diagnoses confirmed by structured interview. Affect balance style categories were calculated as follows: healthy (high PA/low NA), low (low PA/low NA), reactive (high PA/high NA), and depressive (low PA/high NA). Results. Compared with controls, FM patients had lower levels of PA (P ؍ 0.0031; P values are adjusted for multiple testing), higher levels of NA (P ؍ 0.0061), lower levels of functioning (P < 0.0001), and more clinical disorders (P ؍ 0.0031). Groups differed regarding affect balance style (P ؍ 0.0061), with FM patients being more likely than controls to be categorized as depressive (odds ratio 5.60) and reactive (odds ratio 3.81). FM patients and controls with reactive and depressive affect balance styles reported poorer functioning (P < 0.0001) compared with patients with healthy affect balance style. Finally, there was an association between affect balance style and psychiatric comorbidity (P < 0.0001), with patients with depressive and reactive affect balance styles having a 9.00 and 4.75 odds ratio, respectively, of having psychiatric comorbidity compared with patients with healthy affect balance style. Conclusion. Depressive (low PA, high NA) and reactive (high PA, high NA) affect balance styles were predominant in FM patients and related to poor functioning and psychiatric comorbidity.
Body and self-image are important issues for individuals with SLE. Yet participants in our study generally felt that their health care providers did not give enough consideration to their concerns over the outward appearance effects of both the disease and its treatment.
Background-There is no evidence of current or previous B. burgdorferi infection in most patients evaluated at University-based Lyme disease referral centers. Instead, psychological factors likely exacerbate the persistent diffuse symptoms or "Chronic Multisymptom Illness" incorrectly ascribed to an ongoing chronic infection with B. burgdorferi. The objective of this study was to assess the medical and psychiatric status of such patients and compare these findings to those from patients without CMI.

Objective. To evaluate the prevalence and role of psychiatric comorbidity and other psychological factors in patients with chronic Lyme disease (CLD). Methods. We assessed 159 patients drawn from a cohort of 240 patients evaluated at an academic Lyme disease referral center. Patients were screened for common axis I psychiatric disorders (e.g., depressive and anxiety disorders); structured clinical interviews confirmed diagnoses. Axis II personality disorders, functional status, and traits like negative and positive affect and pain catastrophizing were also evaluated. A physician blind to psychiatric assessment results performed a medical evaluation. Two groups of CLD patients (those with post-Lyme disease syndrome and those with medically unexplained symptoms attributed to Lyme disease but without Borrelia burgdorferi infection) were compared with 2 groups of patients without CLD (patients recovered from Lyme disease and those with an identifiable medical condition explaining symptoms attributed to Lyme disease). Results. After adjusting for age and sex, axis I psychiatric disorders were more common in CLD patients than in comparison patients (P ؍ 0.02, odds ratio 2.64, 95% confidence interval 1.30 -5.35), but personality disorders were not. Patients with CLD had higher negative affect, lower positive affect, and a greater tendency to catastrophize pain (P < 0.001) than comparison patients. All psychological factors except personality disorders were related to level of functioning. A predictive model based on these psychological variables was confirmed. Fibromyalgia was diagnosed in 46.8% of CLD patients. Conclusion. Psychiatric comorbidity and other psychological factors distinguished CLD patients from other patients commonly seen in Lyme disease referral centers, and were related to poor functional outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
