Objectives. This study compares the effects of an integrated yoga program with brief supportive therapy in breast cancer outpatients undergoing adjuvant radiotherapy at a cancer center. Methods. Eighty-eight stage II and III breast cancer outpatients are randomly assigned to receive yoga (n = 44) or brief supportive therapy (n = 44) prior to radiotherapy treatment. Assessments include diurnal salivary cortisol levels 3 days before and after radiotherapy and self-ratings of anxiety, depression, and stress collected before and after 6 weeks of radiotherapy. Results. Analysis of covariance reveals significant decreases in anxiety ( P < .001), depression ( P = .002), perceived stress ( P < .001), 6 a.m. salivary cortisol ( P = .009), and pooled mean cortisol ( P = .03) in the yoga group compared with controls. There is a significant positive correlation between morning salivary cortisol level and anxiety and depression. Conclusion. Yoga might have a role in managing self-reported psychological distress and modulating circadian patterns of stress hormones in early breast cancer patients undergoing adjuvant radiotherapy.
Objectives:This study compares the effects of an integrated yoga program with brief supportive therapy on distressful symptoms in breast cancer outpatients undergoing adjuvant radiotherapy.Materials and Methods:Eighty-eight stage II and III breast cancer outpatients were randomly assigned to receive yoga (n = 44) or brief supportive therapy (n = 44) prior to their radiotherapy treatment. Intervention consisted of yoga sessions lasting 60 min daily while the control group was imparted supportive therapy once in 10 days during the course of their adjuvant radiotherapy. Assessments included Rotterdam Symptom Check List and European Organization for Research in the Treatment of Cancer—Quality of Life (EORTC QoL C30) symptom scale. Assessments were done at baseline and after 6 weeks of radiotherapy treatment.Results:A GLM repeated-measures ANOVA showed a significant decrease in psychological distress (P = 0.01), fatigue (P = 0.007), insomnia (P = 0.001), and appetite loss (P = 0.002) over time in the yoga group as compared to controls. There was significant improvement in the activity level (P = 0.02) in the yoga group as compared to controls. There was a significant positive correlation between physical and psychological distress and fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, and constipation. There was a significant negative correlation between the activity level and fatigue, nausea and vomiting, pain, dyspnea, insomnia, and appetite loss.Conclusion:The results suggest beneficial effects with yoga intervention in managing cancer-and treatment-related symptoms in breast cancer patients.
Background:Studies have shown that distress and accompanying neuroendocrine stress responses as important predictor of survival in advanced breast cancer patients. Some psychotherapeutic intervention studies have shown have modulation of neuroendocrine-immune responses in advanced breast cancer patients. In this study, we evaluate the effects of yoga on perceived stress, sleep, diurnal cortisol, and natural killer (NK) cell counts in patients with metastatic cancer.Methods:In this study, 91 patients with metastatic breast cancer who satisfied selection criteria and consented to participate were recruited and randomized to receive “integrated yoga based stress reduction program” (n = 45) or standard “education and supportive therapy sessions” (n = 46) over a 3 month period. Psychometric assessments for sleep quality were done before and after intervention. Blood draws for NK cell counts were collected before and after the intervention. Saliva samples were collected for three consecutive days before and after intervention. Data were analyzed using the analysis of covariance on postmeasures using respective baseline measure as a covariate.Results:There was a significant decrease in scales of symptom distress (P < 0.001), sleep parameters (P = 0.02), and improvement in quality of sleep (P = 0.001) and Insomnia Rating Scale sleep score (P = 0.001) following intervention. There was a decrease in morning waking cortisol in yoga group (P = 0.003) alone following intervention. There was a significant improvement in NK cell percent (P = 0.03) following intervention in yoga group compared to control group.Conclusion:The results suggest modulation of neuroendocrine responses and improvement in sleep in patients with advanced breast cancer following yoga intervention.
Background:Cancer-related fatigue is widely prevalent in cancer patients and affects quality of life in advanced cancer patients. Fatigue is caused due to both psychologic distress and physiological sequel following cancer progression and its treatment. In this study, we evaluate the effects of yogic intervention in managing fatigue in metastatic breast cancer patients.Methods:Ninety-one patients with metastatic breast cancer were randomized to receive integrated yoga program (n = 46) or supportive therapy and education (n = 45) over a 3-month period. Assessments such as perceived stress, fatigue symptom inventory, diurnal salivary cortisol, and natural killer cell counts were carried out before and after intervention. Analysis was done using an intention-to-treat approach. Postmeasures for the above outcomes were assessed using ANCOVA with respective baseline measure as a covariate.Results:The results suggest that yoga reduces perceived stress (P = 0.001), fatigue frequency (P < 0.001), fatigue severity (P < 0.001), interference (P < 0.001), and diurnal variation (P < 0.001) when compared to supportive therapy. There was a positive correlation of change in fatigue severity with 9 a.m. salivary cortisol levels.Conclusion:The results suggest that yoga reduces fatigue in advanced breast cancer patients.
The aim of this study is to determine whether treatment increases the levels of anti-Proteus antibodies (APA) in patients with rheumatoid arthritis (RA). The blood samples of 32 patients suffering from RA who were recruited in our previous study and continued to participate in our follow-up study were collected after 1 year. Their first and follow-up samples were analysed for the presence of IgG isotype and total immunoglobulins (IgG+IgA+IgM) against Proteus mirabalis (PM) using enzyme-linked immunosorbent assay with two kinds of antigen preparations: whole bacteria and sodium dodecyl sulphate (SDS) lysed bacterial extract. All patients were treated with methotrexate and hydroxychloroquine with adequate dose of non-steroidal anti-inflammatory drug. After 1 year, 11 patients were in clinical remission [erythrocyte sedimentation rate (ESR) less than 30 mm/h and C-reactive protein (CRP) less than or equal to 10 mg/l], while the rest of the 21 were in the state of active disease. Correlation and Student's t test were used for statistical analysis. APA titres were significantly elevated in patients after 1 year of therapy. However, the rise was not different between patients who were in clinical remission and those in the state of active disease. APA titre increases in the treatment of RA, and the probable mechanisms are discussed.
Proteus mirabilis (PM) is implicated in different studies in the pathogenesis of rheumatoid arthritis (RA) because of the structural homogeneity of its haemolysin B precursor with EQRRAA sequences in DRB 1 haplotype. The aim of the study was to compare the levels of antibodies specific to PM in the sera of patients with RA and healthy controls in our population. Serum samples from 78 consecutive RA patients and 75 healthy controls were analysed for the presence of IgG isotype and total immunoglobulins (IgG + IgA + IgM) against PM using enzyme-linked immunosorbent assay (ELISA) with two kinds of antigen preparations, whole bacteria and SDS-lysed bacterial extract. There was no significant increase in the concentrations of anti- Proteus antibodies (APA) in patients with RA compared to healthy controls in our population, when SDS-lysed bacterial extract or whole bacteria were used as antigen. The APA levels did not correlate with serum CRP levels. We conclude that P. mirabilis has no pathological or aggravating role in RA.
Objective To describe the distribution of specific mitochondrial DNA (mtDNA) haplogroups (hgs) in a cohort of patients with rheumatoid arthritis (RA). Methods Two-hundred nineteen consecutive patients with RA had mtDNA isolated from their blood, sequenced and haplotyped. Patients were diagnosed according to the American College of Rheumatology (ACR)/European league against Rheumatism (EULAR) criteria. Demographic and clinical data were retrieved from the Danish nationwide database (DANBIO). Logistic regression analyses were performed to test for associations. Results One-hundred eighty-four patients were eligible for analysis. Haplogroup frequencies were: H (n = 88; 47.8%), U (n = 37; 20.1%), T (n = 22; 12.0%), J (n = 16; 8.7%), K (n = 11; 5.9%), HV (n = 6; 3.3%) and V (n = 4; 2.2%). The distribution of individual hgs was identical to the background population. Radiographic erosions were significantly associated with hg clusters JT (OR = 2.37, 95% confidence interval (CI): 1.07-5.53, p = 0.038). Significantly fewer patients from hg cluster JT received biological treatment (OR = 0.17, 95% CI: 0.03-0.87, p = 0.038). Albeit, none of these associations were significant when corrected for multiple tests.
