Low-to-moderate intensity aerobic exercise training modulates irritable bowel syndrome through antioxidative and inflammatory mechanisms in women: Results of a randomized controlled trial. Cytokine 2018; 102:18-25. [PMID: 29274540 DOI: 10.1016/j.cyto.2017.12.016] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Revised: 12/12/2017] [Accepted: 12/14/2017] [Indexed: 02/07/2023]
Abstract
Our aim was to explore the putative beneficial effects of low-to-moderate intensity exercise training program in patients with irritable bowel syndrome (IBS). This study evaluated the changes in blood oxidative stress status, inflammatory biomarkers and IBS severity symptoms following 24 weeks of moderate aerobic exercise in sedentary IBS patients. A total of 109 female volunteers (aged 18-41 yrs) who fulfilled Rome III criteria for the diagnosis of IBS were screened and 60 were randomized to exercise (EX, n = 30) and non-exercise (NON-EX, n = 30) groups. Exercise intervention favorably attenuated inflammation as indicated by plasma cytokines (IL-1β, IL-6, IL-8, IL-10 and TNF-α), adenosine deaminase, oxidative stress (XO, MDA and NO) and enhanced antioxidants (SOD, CAT and GSH-Px) (P < .05), and these alterations correlate with promising improvements in IBS symptoms (P < .05). Taken together, low-to-moderate intensity exercise training program attenuates symptoms in IBS. Symptom improvement was associated with a reversal of the ratio of anti- to pro-inflammatory cytokines as well as facilitating blood redox homeostasis, suggesting an immune- and redox modulating function for exercise training.

Abstract
BACKGROUND An individual's level of physical activity is one of a set of lifestyle and behavioral factors that can affect immune function and health. METHODS The purpose of this review is to summarize the current knowledge in this research field and to review the recent developments in exercise immunology. RESULTS Most studies show that regular exercise training increases immune competence and reduces the risk of infection compared to a sedentary lifestyle. In contrast, acute prolonged bouts of exercise and periods of intensified training are followed by a temporary increase in the risk of infection. These observations have been attributed to differential exercise-induced changes of a series of humoral and cellular immune system parameters. Furthermore, regular exercise training is a countermeasure against a persistent systemic inflammatory state which is a typical feature of cardiovascular and metabolic diseases is by lowering levels of pro-inflammatory cytokines. It is supposed that these effects are mediated by a modification of metabolic signals and innate immune regulation, the release of anti-inflammatory cytokines from muscle, the release of stress hormones, and a process known as browning of adipose tissue. CONCLUSION The effects of physical activity on the immune system strongly depend on the mode and intensity of exercise or training. Thereby, considerable knowledge has accumulated concerning the significance of exercise as an important lifestyle factor for prevention and therapy of major chronic diseases.

Abstract
Paraneoplastic syndromes in lymphatic or myeloid neoplasms can present with musculoskeletal symptoms, vasculitis-like or febrile symptoms. Hematologic diseases are also associated with rheumatic diseases whereas inflammatory rheumatic diseases are often associated with an increased risk for lymphoproliferative disease. Atypical disease characteristics, lack of disease-specific antibodies or therapeutic response are red flags for diagnosing paraneoplastic or coexistent malignant diseases. New onset of systemic symptoms, worsening of general condition, night sweats or weight loss need to be considered during follow-up and differential diagnostics. This article focuses on musculoskeletal, vasculitis-like and systemic signs of lymphatic or myeloid neoplasms either because of coexistency, tumor association or paraneoplastic disease.

Abstract
The strong coupling constant α s is determined from inclusive jet and dijet cross sections in neutral-current deep-inelastic ep scattering (DIS) measured at HERA by the H1 collaboration using next-to-next-to-leading order (NNLO) QCD predictions. The dependence of the NNLO predictions and of the resulting value ofα s ( m Z ) at the Z-boson mass m Z are studied as a function of the choice of the renormalisation and factorisation scales. Using inclusive jet and dijet data together, the strong coupling constant is determined to beα s ( m Z ) = 0.1157 ( 20 ) exp ( 29 ) th . Complementary,α s ( m Z ) is determined together with parton distribution functions of the proton (PDFs) from jet and inclusive DIS data measured by the H1 experiment. The valueα s ( m Z ) = 0.1142 ( 28 ) tot obtained is consistent with the determination from jet data alone. The impact of the jet data on the PDFs is studied. The running of the strong coupling is tested at different values of the renormalisation scale and the results are found to be in agreement with expectations.

Abstract
Long-term cigarette smoking induces inflammatory processes in the pulmonary system that are suggested to "spill over" into systemic inflammation. Regular exercise has been shown to have anti-inflammatory properties. The aim of the study was to investigate the effects of therapeutic exercise on inflammation and muscle wasting in smoke-exposed mice. C57BL/6J mice ( n = 30) were separated into three groups to receive either 1) no specific treatment (control group), 2) 8-mo exposure to cigarette smoke [smoke-exposed (SE) group], or 3) 8 mo of cigarette smoke combined with exercise training during the last 2 mo (SEex group). The inflammatory status was analyzed by quantifying levels of various plasma proteins using multiplex ELISA and detection of lymphocyte surface markers by flow cytometry. Muscle tissue was analyzed by histological techniques and measurements of RNA/protein expression. SE led to decreased maximal O2 uptake (V̇o2max) and maximal running speed ( Vmax), which was reversed by exercise ( P < 0.05). Expression of ICAM-1, VCAM-1, and CD62L on T cells increased and was reversed by exercise ( P < 0.05). Similarly, SE induced an increase of various inflammatory cytokines, which were downregulated by exercise. In muscle, exercise improved the structure, oxidative capacity, and metabolism by reducing ubiquitin proteasome system activation, stimulating insulin-like growth factor 1 expression, and the SE-induced inhibition of mammalian target of rapamycin signaling pathway ( P < 0.05). Exercise training reverses smoke-induced decline in exercise capacity, systemic inflammation, and muscle wasting by addressing immune-regulating, anabolic, and metabolic pathways.

Abstract
INTRODUCTION High-intensity interval training (HIT) exercise has gained much interest in both performance and recreational sports. This study aims to compare the effect of HIT versus continuous (CONT) exercise with regard to changes of circulating T cells and progenitor cells. METHODS Subjects (n = 23) completed an HIT test and an isocaloric CONT test. Blood samples were collected before, immediately after, and 3 and 24 h postexercise for the assessment of low differentiated (CD3CD28CD57), highly differentiated T cells (CD3CD28CD57), regulatory T cells (Tregs) (CD4CD25CD127), hematopoietic progenitor cells (CD45CD34), and endothelial progenitor cells (CD45CD34KDR) by flow cytometry. The detection of apoptosis was performed by using labeling with annexin V. To analyze potential mechanisms affecting T cells, several hormones and metabolites were analyzed. RESULTS Both exercise tests induced an increase of catecholamines, cortisol, and thiobarbituric acid-reactive substances (P < 0.05). CONT induced a higher increase of apoptosis in low differentiated T cells compared with the HIT (CONT: 3.66% ± 0.21% to 6.48% ± 0.29%, P < 0.05; HIT: 3.43% ± 0.31% to 4.71% ± 0.33%), whereas HIT was followed by a higher rate of apoptotic highly differentiated T cells (CONT: 21.45% ± 1.23% to 25.32% ± 1.67%; HIT: 22.45% ± 1.37% to 27.12% ± 1.76%, P < 0.05). Regarding Tregs, HIT induced a mobilization, whereas CONT induced apoptosis in these cells (P < 0.05). The mobilization of progenitor cells did not differ between the exercise protocols. CONCLUSION These results suggest that HIT deletes mainly highly differentiated T cells known to affect immunity to control latent infections. By contrast, CONT deletes mainly low differentiated T cells and Tregs, which might affect defense against new infectious agents.

Abstract
Rheumatoid arthritis is the most common inflammatory rheumatic disease. Due to the destruction of joints in the course of the disease it leads to significant morbidity in affected patients. The quality of life and even life expectancy can be severely impaired. Early diagnosis and early initiation of treatment is a decisive step towards a more benign course of the disease. New classification criteria have been published in order to help in early diagnosis. Methods of imaging, such as ultrasound and magnetic resonance imaging help in the detection of synovitis, which is the major pathomorphological manifestation of arthritis and should be identified without any doubt. Treatment follows the rule of treat to target with the aim of achieving remission or if this is not realistic, at least the lowest possible level of disease activity. The first and perhaps most important step in therapy is the initiation of methotrexate or if contraindications are present, another disease-modifying antirheumatic drug (DMARD) as soon as the diagnosis is made. Initial addition of glucocorticoids is recommended, which should be reduced in dose and terminated as soon as possible. Furthermore, either the combination of different DMARDs or the start of biologic DMARDs, such as tumor necrosis factor alpha (TNF-alpha) inhibitors or second generation biologic DMARDs is possible as a treatment option. The treatment follows the rule of shared decision-making and is the standard to treat comorbidities, the use an interdisciplinary approach and to treat functional deficits by rehabilitation measures, such as physiotherapy.

Abstract
BACKGROUND Numerous studies have reported favorable outcomes using drug-coated balloons (DCBs) for treatment of symptomatic peripheral artery disease of the superficial femoral and popliteal arteries. However, the treatment effect compared with an uncoated balloon has differed greatly among the randomized trials, with better outcomes observed with higher-dose DCBs. This European trial was designed to assess the safety and effectiveness of a next-generation low-dose (2-µg/mm2 surface dose of paclitaxel) DCB. METHODS This was a prospective, randomized, multicenter, single-blinded trial. Patients were randomized (3:1) to treatment with a low-dose DCB or an uncoated percutaneous transluminal angioplasty (PTA) balloon. The primary safety end point was a composite of freedom from device- and procedure-related death through 30 days after the procedure and freedom from target limb major amputation and clinically driven target lesion revascularization through 12 months after the procedure. The primary effectiveness end point was primary patency at 12 months. RESULTS Patients were randomized to treatment with a DCB (222 patients, 254 lesions) or uncoated PTA balloon (72 patients, 79 lesions) after successful predilatation. Mean lesion length was 7.2 and 7.1 cm, and 19.2% and 19.0% of lesions represented total occlusions, respectively. The primary safety end point was met, and superiority was demonstrated; freedom from a primary safety event was 94.1% (193 of 205) with DCB and 83.3% (50 of 60) with PTA, for a difference of 10.8% (95% confidence interval, 0.9%-23.0%). The primary effectiveness end point was met, and superiority of DCB over PTA was achieved (83.9% [188 of 224] versus 60.6% [40 of 66]; P<0.001). Outcomes with DCB were also superior to PTA per the Kaplan-Meier estimate for primary patency (89.0% versus 65.0% at 365 days; log-rank P<0.001) and for rates of clinically driven target lesion revascularization (5.9% versus 16.7%; P=0.014). CONCLUSIONS Superiority with a low-dose DCB for femoropopliteal interventions was demonstrated over PTA for both the safety and effectiveness end points.

Abstract
Pulmonary hypertension (PH) is characterized by severe exercise limitation mainly attributed to the impairment of right ventricular function resulting from a concomitant elevation of pulmonary vascular resistance and pressure. The unquestioned cornerstone in the management of patients with pulmonary arterial hypertension (PAH) is specific vasoactive medical therapy to improve pulmonary hemodynamics and strengthen right ventricular function. Nevertheless, evidence for a beneficial effect of exercise training (ET) on pulmonary hemodynamics and functional capacity in patients with PH has been growing during the past decade. Beneficial effects of ET on regulating factors, inflammation, and metabolism have also been described. Small case-control studies and randomized clinical trials in larger populations of patients with PH demonstrated substantial improvements in functional capacity after ET. These findings were accompanied by several studies that suggested an effect of ET on inflammation, although a direct link between this effect and the therapeutic benefit of ET in PH has not yet been demonstrated. On this background, the aim of the present review is to describe current concepts regarding the effects of exercise on the pulmonary circulation and pathophysiological limitations, as well as the clinical and mechanistic effects of exercise in patients with PH.

Abstract
PURPOSE The purpose of this double-blind, randomized, placebo-controlled clinical trial was to investigate the effects of the natural combination medicine Traumeel (Tr14) consisting of 14 diluted biological and mineral components on the inflammatory immune response and recovery up to 72 h after repetitive bouts of bicycle tests. METHODS Antigen-stimulated IL-1ra and IL-6 were defined as primary outcome measures. Moreover, various immunological and serum muscle damage markers were investigated. The evaluation was performed using the score of the area under the curve with respect to increase (AUCi) for 24 and 72 h after the second exercise test (EX2). RESULTS The Tr14 group indicated a lower decrease of lymphocytes by tendency (p = 0.06) and a lower activation of lymphocyte activation markers (CD62L absolute: p = 0.04; CD69: p = 0.01 and CD69 absolute: p = 0.05) in the period 24 h after EX2. In addition, the Tr14 group indicated a higher expression of antigen-stimulated CCL3 (p = 0.01), CCL4 (p = 0.07) and serum CCL2 (p = 0.05) in the period 24 h after EX2. There was a tendentially lower decrease of monocytes (p = 0.09) and a lower expression of antigen-stimulated MMP-3 (p = 0.01) in the Tr14 group in the period 72 h after EX2. However, antigen-stimulated IL-1ra and IL-6 showed no group differences. CONCLUSION In line with the previous results, it was shown that Tr14 attenuates the adaptive immune response partially. Furthermore, the results indicate that Tr14 is able to stimulate the innate immune system via an increased production of pro-inflammatory chemokines. It is speculated that the higher expression of chemokines might play a role in the regeneration and recovery after exercise.

Abstract
Psoriatic arthritis is a chronic inflammatory disease of the musculoskeletal system with association to skin psoriasis and is characterized by variable clinical symptoms with very heterogeneous degrees of disease suffering for patients. Clinical manifestations essentially include alterations to the skin and nails, peripheral arthritis, enthesitis, dactylitis and/or spinal involvement. This variability necessitates an individualized therapy of patients with different therapy targets. Apart from international guidelines no therapy recommendations are available in Germany for treatment of psoriatic arthritis. For this reason this article summarizes the established points, characteristics and aspects to be considered in the therapy of psoriatic arthritis in Germany, taking the various main forms of the disease into consideration.

Abstract
Due to the increasing prevalence of gout, particularly in old age, the disease is becoming of increasing importance in Germany. Gout is one of the most common forms of recurrent inflammatory arthritis and is induced by the deposition of monosodium urate crystals in synovial fluid and other tissues. The principal goals of therapy in chronic gout are the symptomatic treatment of the acute joint inflammation and the causal treatment of the underlying metabolic cause, the hyperuricemia. Only a consistent and permanent reduction of the serum uric acid level ultimately results in an efficient avoidance of further gout attacks and therefore the prevention of structural damage. Due to an often inadequate treatment of gout, the target of healing the disease is often not achieved. A correct and timely diagnosis and adequate assessment of comorbidities associated with gout are, however, of substantial importance for patient and physician to achieve remission of the disease. In order to create a solid basis for a timely and effective treatment of affected patients, in 2016 the German Society of Rheumatology (DGRh) initiated the development of S2e guidelines on gouty arthritis for specialists. This article summarizes these S2e guidelines on the management of gouty arthritis in the specialist sector.

Abstract
Cardiovascular (CV) events are among the most important comorbidities and are the major cause of death in inflammatory rheumatic diseases, such as rheumatoid arthritis (RA). Disease activity and traditional CV risk factors contribute to the total CV risk. Among the antirheumatic drugs used for long-term treatment of RA, non-steroidal anti-inflammatory drugs (NSAID) and glucocorticoids lead to an increased risk but disease-modifying antirheumatic drugs (DMARD), such as hydroxychloroquine, methotrexate and especially biologics significantly reduce the risk. Besides achieving the best possible disease control, rheumatologists should identify additional CV risk factors and also initiate adequate treatment in order to reduce or even eliminate the CV risk. When treating rheumatic diseases possible drug-induced elevation of CV risk must be considered. Finally, the CV risk should be regularly monitored.

Abstract
The aim of this study was to investigate whether honey supplementation (70g, ninety minutes before each training session) attenuates changes in lymphocyte counts, DNA damage, cytokines, antioxidative and peroxidative biomarkers following moderate-to-intensive exercise training in male road cyclists. Healthy nonprofessional cyclists (n=24, aged 17-26years) were randomly assigned to exercise+supplement (EX+S, n=12) and exercise (EX, n=12) groups for an experimental period of 16weeks. Moderate-to-intensive exercise training increased lymphocytes DNA damage, cytokines and peroxidative biomarkers as well as decreased antioxidative biomarkers in the EX group. These changes were significantly attenuated in the EX+S group. Furthermore, for both groups the observed changes in peroxidative and antioxidative biomarkers could be correlated positively and negatively, respectively, with lymphocyte DNA damage and cytokines. Findings suggest that honey attenuates oxidative stress and lymphocyte DNA damage after exercise, activities that are most likely attributable to its high antioxidant capacity.

Abstract
Strenuous exercise is followed by an elevation of many cytokines with inflammation regulating properties. Since most cytokines act at pico- or nanomolar concentrations many investigations failed to detect their concentrations in vivo. Hence, the aim of this study was to evaluate the significance of cytokine measurements (IL-1β, TNF-α, IL-1ra, IL-6, CCL2 and CXCL8) in a stimulated whole-blood culture (sWBC) compared to serum with respect to their exercise-induced kinetics and detection rates. 40 male volunteers (age: 25,5±4,3years, BMI: 24,00±2,24, VO2peak: 46,9±4,1mL/kg×min) performed 60min of intensive bicycle exercise (80% VO2peak). Blood samples were taken before and for up to 24h after exercise. All cytokines were determined by a multiplex ELISA. There were weak to moderate correlations between cytokines in sWBC and serum. While exercise did not affect pro-inflammatory cytokines in serum, in sWBC only IL-1β was increased 1.2-fold at 3h (p<0,05). All other cytokines increased both in sWBC and serum. The detection rate was superior in sWBC vs serum for most cytokines. Exercise-induced cytokine kinetics in sWBC do not reflect systemic changes. Both approaches provide a synergistic insight into inflammatory processes on the cytokine level.

Abstract
Mainly due to the general demographic changes and decreasing mortality in rheumatic diseases based on therapeutic progress, the proportion of older patients treated by rheumatologists is growing. Drug treatment in the elderly, however, harbors certain risks including age-specific pharmacokinetic features and high rates of multimorbidity and polypharmacy resulting in a risk of drug interactions and adherence problems. Nevertheless, older patients suffering from rheumatic diseases ought to be treated with the same intensity and same targets as the younger counterparts. Bearing all these facts in mind it is a balancing act for rheumatologists to find an optimal treatment for the individual elderly patient. Fear of risks should not lead to hesitant use of drugs leaving these patients alone with treatment deficits, as some studies have suggested.

Abstract
Introduction: Postpancreatectomy haemorrhage (PPH) is a dangerous complication after pancreatic resection. Patients and Methods: From 2006 to 2015, 400 consecutive pancreatic head resections and pancreatectomies were performed and prospectively documented. This study analysed incidence, treatment and outcome of patients with PPH. Results: Incidence of PPH was 5.5 % (n = 22). PPH occurred in a median of eight days after pancreatic surgery with an equal frequency of symptoms being caused by gastrointestinal bleeding (n = 11) and abdominal bleeding (n = 11). Postoperative pancreatic fistulas (POPF) were significantly more frequent in case of PPH (45 % POPF in case of PPH vs. 20 % POPF in case of no PPH, p < 0.01). PPH was more frequent after pancreatogastrostomy (8/70; 11 %) than after pancreatojejunostomy (11/281; 4 %; p = 0.01). The majority of bleedings after pancreatogastrostomy came from the intragastric cut surface of the pancreas. During the first week, relaparotomy was significantly more frequent (n = 5; 56 %) than in late PPH (n = 1; 8 %; p = 0.01). In late PPH, interventions (angiography; n = 7, endoscopy; n = 4) were more frequent. In 16 severe cases, surgical/interventional bleeding control (n = 12) or relevant transfusions of more than 3 units of packed red blood cells (n = 4) were performed. Compared with the whole group, mortality was significantly increased in case of PPH (13.6 % in case of PPH vs. 3.7 % in case of no PPH; p = 0.03). Conclusion: PPH is an episodic and potentially life-threatening complication with an increased mortality rate, which is frequently associated with impaired healing of the pancreatic anastomosis. Diagnostic investigation and treatment of PPH requires an experienced surgical centre with a close cooperation with endoscopy and (interventional) radiology.
