The effects in vitro of TNF-α and its antagonist 'etanercept' on ejaculated human sperm.

Tumour necrosis factor (TNF)-α is primarily involved in the regulation of cell proliferation and apoptosis; in addition it possesses pro-inflammatory properties. Anti-TNF-α strategies involve either administration of anti-TNF-α antibody or soluble TNF receptor to mop up circulating TNF-α. Etanercept, a recombinant human TNF-α receptor, was found to be effective in the treatment of rheumatoid arthritis. The impact of TNF-α inhibitors on human fertility is of notable interest. This in vitro study investigated the effect of different concentrations of TNF-α and etanercept used alone or in combination on sperm viability, motility, mitochondrial function, percentage of apoptosis and chromatin integrity in swim-up selected human spermatozoa. A negative effect of TNF-α (300 and 500ng mL-1) and etanercept (from 800µg mL-1 to 2000µg mL-1) individually on sperm viability, motility, mitochondrial function, percentage of apoptotic spermatozoa and sperm DNA integrity was demonstrated. However, at concentrations of 100 and 200µg mL-1, etanercept can block, in a significant way, the toxic effects of TNF-α (500ng mL-1) on studied sperm characteristics. Our results confirm that TNF-α has a detrimental effect on sperm function and suggest, for the first time, that etanercept may counteract the in vitro toxic action of TNF-α. This data appears to be quite promising, although further studies, both in vivo and in vitro, are needed to understand the exact mechanism of action of TNF-α and TNF-α antagonists on sperm function.

Effect of Mud-Bath Therapy on Serum Biomarkers in Patients with Knee Osteoarthritis: Results from a Randomized Controlled Trial.

BACKGROUND: Balneotherapy is one of the most commonly used non-pharmacological approaches for osteoarthritis (OA). Recent data indicate that some biomarkers could be useful to predict OA progression and to assess therapeutic response. OBJECTIVES: To evaluate the effects of mud-bath therapy on serum biomarkers in patients with knee OA. METHODS: The study group comprised 103 patients with primary symptomatic bilateral knee OA who were randomly assigned to receive a cycle of mud-bath therapy over a period of 2 weeks or to continue their standard therapy alone. Clinical and biochemical parameters were assessed at baseline and after 2 weeks. Clinical assessments included global pain score on a visual analogue scale (VAS) and the Western Ontario and McMaster Universities Index (WOMAC) subscores for knee OA. Cartilage oligomeric matrix protein (COMP), C-terminal cross-linked telopeptide type II collagen (CTX-II), myeloperoxidase (MPO) and high sensitivity C-reactive protein (hsCRP) serum levels were assessed by ELISA. RESULTS: At the end of mud-bath therapy we observed a statistically significant improvement in VAS and WOMAC subscores. Serum levels of COMP, MPO and hsCRP did not show any significant modification in either group, while a significant increase (P < 0.001) in CTX-II serum levels was observed in the mud-bath group after the treatment. CONCLUSIONS: A cycle of mud-bath therapy added to the usual treatment had a beneficial effect on pain and function in patients with knee OA. The evaluation of serum biomarkers showed a significant increase of CTX-II only, perhaps due to an increase of cartilage turnover induced by thermal stress.

One year in review: novelties in the treatment of rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic disease characterised by inflammation of the synovial tissue in joints, which can lead to joint destruction. The primary aim of the treatment is to control pain and inflammation, reduce joint damage and disability, and maintain or improve physical function and quality of life. In this article, we provide a critical analysis of the recent literature on the novelties in the treatment of RA, with a particular focus on the most relevant studies published over the last two years.

Short-Term Effect of Topical Cetylated Fatty Acid on Early and Advanced Knee Osteoarthritis: A Multi-Center Study.

OBJECTIVES: This study aims to investigate if short-term topical treatment with cetylated fatty acid (CFA) cream reduces the detrimental effects of early and advanced knee osteoarthritis (OA). PATIENTS AND METHODS: The study included 113 patients (32 males, 81 females; median age 70.0 years; 95% CI: 69.0 to 71.4 years) with knee OA diagnosed according to American College of Rheumatology classification criteria. Each patient underwent knee X-rays, followed by a CFA topical treatment (two applications per day for one week). Before and after the treatment, patients completed a Western Ontario and McMaster Universities Osteoarthritis Index questionnaire. All knee X-rays were classified according to Kellgren-Lawrence scale. RESULTS: After one week of treatment, decreased Western Ontario and McMaster Universities Osteoarthritis Index overall scores and sub-scale scores were observed in the whole cohort (p<0.005) and Kellgren-Lawrence scale grade 3 group (p<0.05). In the Kellgren-Lawrence scale grade 2 group, overall Western Ontario and McMaster Universities Osteoarthritis Index scores and pain and functional ability sub-scale scores improved (p<0.05). CONCLUSION: Administration of topical CFA may mitigate most common symptoms in knee OA. Our findings suggest that topical CFA is effective in all knee OA patients with slightly higher evidence for those with advanced disease.

Gemcitabine, oxaliplatin, levofolinate, 5-fluorouracil, granulocyte-macrophage colony-stimulating factor, and interleukin-2 (GOLFIG) versus FOLFOX chemotherapy in metastatic colorectal cancer patients: the GOLFIG-2 multicentric open-label randomized phase III trial.

The GOLFIG-2 phase III trial was designed to compare the immunobiological activity and antitumor efficacy of GOLFIG chemoimmunotherapy regimen with standard FOLFOX-4 chemotherapy in frontline treatment of metastatic colorectal cancer (mCRC) patients. This trial was conceived on the basis of previous evidence of antitumor and immunomodulating activity of the GOLFIG regimen in mCRC. GOLFIG-2 is a multicentric open/label phase III trial (EUDRACT: 2005-003458-81). Chemo-naive mCRC patients were randomized in a 1:1 ratio to receive biweekly standard FOLFOX-4 or GOLFIG [gemcitabine (1000 mg/m(2), day 1); oxaliplatin (85 mg/m(2), day 2); levofolinate (100 mg/m(2), days 1-2), 5-fluorouracil (5-FU) (400 mg/m(2) in bolus followed by 24 h infusion at 800 mg/m(2),days 1-2), sc. GM-CSF (100 µg, days 3-7); sc. aldesleukin (0·5 MIU bi-daily, days 8-14 and 17-30)] treatments. The study underwent early termination because of poor recruitment in the control arm. After a median follow-up of 43.83 months, GOLFIG regimen showed superiority over FOLFOX in terms of progression-free survival [median 9·23 (95% confidence interval (CI), 6·9-11.5) vs. median 5.70 (95% CI, 3.38-8.02) months; hazard ratio (HR): 0.52 (95% CI, 0.35-0.77), P=0·002] and response rate [66.1% (95% CI, 0.41-0.73) vs. 37·0% (95% CI, 0.28-0.59), P=0.002], with a trend to longer survival [median 21.63 (95% CI, 18.09-25.18) vs. 14.57 mo (95% CI, 9.07-20.07); HR: 0·79 (95% CI, 0.52-1.21); P=0.28]. Patients in the experimental arm showed higher incidence of non-neutropenic fever (18.5%), autoimmunity signs (18.5%), an increase in the number of monocytes, eosinophils, CD4(+) T lymphocytes, natural killer cells, and a decrease in immunoregulatory (CD3(+)CD4(+)CD25(+)FoxP3(+)) T cells. Taken together, these findings provide proof-of-principle that GOLFIG chemoimmunotherapy may represent a novel reliable option for first-line treatment of mCRC.

Fibromyalgia syndrome and spa therapy: myth or reality?

Fibromyalgia syndrome (FS) is a common musculoskeletal disorder characterized by otherwise unexplained chronic widespread pain, a lowered pain threshold, high tender point counts, sleep disturbances, fatigue, headache, irritable bowel syndrome, morning stiffness, paraesthesias in the extremities, often psychological distress and depressed mood. Consequently, FS has a negative impact on working capacity, family life, social functioning and quality of life. Because of unknown etiology and not clearly understood pathogenesis, there is no standard therapy regime for FS. A variety of medical treatments, including antidepressants, opioids, analgesic or non-steroidal anti-inflammatory drugs, sedatives, muscle relaxants and antiepileptics, have been used to treat FS. Currently, no pharmacological treatment for FS is consistently successful. According to recent guidelines, the optimal treatment of FS requires a multidisciplinary approach with a combination of non-pharmacological and pharmacological treatment modalities. Spa therapy is a popular treatment for FS in many European countries, as well as in Japan and Israel. However, despite their long history and popularity spa treatments are still the subject of debate and their role in modern medicine is still not clear. The objective of this review is to summarize the currently available information on clinical effects and mechanism of action of spa therapy in FS. We also provide some suggestions for further development in this area.
