Cellular adhesion molecules are expressed by activated endothelial cells in severe bum. The release of these molecules can lead to organ damage. We measured E-selectin levels in the blood of 20 severe-burn patients. Then the patients were divided into two groups of 10 patients each. In the study group, atorvastatin 20 mg/day was administered orally for 14 days. In the control group, an equal volume of placebo was administered orally for 14 days. In both groups, following the last dose of the agents, serum E-selectin levels were measured again. Mean burn size and the percentage of third-degree bums of total burned area were not significantly different between the groups. Serum E-selectin level obtained at the beginning of the treatment was 23.69 +/- 2.71 ng/ml in the atorvastatin group and 18.08 +/- 0.97 ng/ml in the control group. Serum E-selectin level obtained at the end of the treatment was 10.86 +/- 1.36 ng/ml in the atorvastatin group and 21.69 +/- 2.11 ng/ml in the control group. The difference between the two groups was statistically significant (p < 0.05). In the comparison of early and late serum E-selectin levels in the atorvastatin group, a significant decrease was obtained (p < 0.05). In the control group, serum E-selectin levels were found to be increased in the late period. However, the difference between the early and late values was nonsignificant (p > 0.05). We concluded that atorvastatin is effective in the prevention of E-selectin release in severely burned patients.
The aim of this retrospective study was to evaluate melanoma biopsy specimens from the Greek population living in the prefecture of Larissa for the presence of human papillomavirus (HPV) DNA and to determine the possible relationship between HPV and clinical outcome in these patients. Twenty-eight melanoma biopsy specimens, 20 from primary cutaneous melanoma and eight from melanoma metastasis were obtained from 28 patients. The biopsy samples were formalin-fixed and paraffin wax-embedded. The control group consisted of three junctional melanocytic nevi, histologically confirmed, and three punch biopsies from normal skin that were obtained from six healthy individuals. The presence and types of HPV DNA were assessed by the amplification of a fragment of the LI region by consensus primer polymerase chain reaction (PCR) combined with restriction fragment length polymorphism analysis (RFLPA). In each biopsy specimen that was evaluated, HPV 6, HPV 11, HPV 16 and HPV 18 positive controls from genital HPV lesions were included. Five of 28 (17.85%) biopsy melanoma specimens were positive for HPV DNA. Conversely, HPV was not detected in any of the biopsy specimens of the control group (0/6). HPV viral type 16 was found in two samples and HPV 6 DNA in three. Our results regarding the possible relationship between melanoma and HPV DNA were not statistically significant (p > 0.05). These findings suggest that ultraviolet sun exposure remains the main cause of melanoma in our region. The role of cutaneous HPV infection in the pathogenesis of melanoma remains elusive.
Chronic low-grade inflammation is associated with insulin resistance. The aim of this study was to determine insulin response to intravenous glucose load and insulin sensitivity in patients with ankylosing spondylitis (AS). Fourteen nonobese male patients with AS and 14 matched healthy controls underwent frequent-sampling intravenous glucose tolerance test (FSIVGTT). Insulin secretion and insulin sensitivity were calculated using the computer-minimal and homeostasis-model assessment 2 (HOMA2) models. Fasting glucose, insulin, cholesterol, high-density lipoprotein and low-density lipoprotein cholesterol, triglyceride levels, HOMA2, glucose effectiveness, insulin sensitivity and insulin response to FSIVGTT did not differ between patients and controls. Tumor necrosis factor-alpha and interleukin (IL)-6 concentrations tended to be higher in AS patients than in controls. Second-phase beta-cell responsiveness was 37% lower (p = 0.05) in AS patients than in controls. A negative correlation was found between the percentage of beta-cell secretion and IL-6 in all subjects (r = -0.54, p = 0.006). We found normal insulin sensitivity but attenuated glucose utilization in the second phase of FSIVGTT in AS patients. Our results indicate that elevated IL-6 levels may play a pathophysiological role in attenuating beta-cell responsiveness, which may explain the association between elevated IL-6 levels and increased risk for type 2 diabetes.
We investigated the urinary pharmacokinetics of monomeric anthocyanins in seven healthy volunteers. The volunteers were administered a single oral dose of 3.57 g total anthocyanins contained in 150 ml of a concentrated elderberry juice under fasting conditions. Within 24 h the urinary excretion of unchanged cyanidin-3,5-diglucoside (cyanidin-3-sambubioside-5-glucoside and cyanidin-3,5-diglucoside were calculated as cyanidin-3,5-diglucoside equivalents), cyanidin-3-glucoside, cyanidin-3-sambubioside and total anthocyanins (i.e., the sum of all quantifiable anthocyanidin glycosides) was 0.16, 0.06, 0.05 and 0.06% of the administered doses, respectively. Maximum excretion rates were determined within 1.0 h after intake. The estimates (arithmetic mean +/- SD) of t(1/2) were 1.25 +/- 0.25, 1.53 +/- 0.36, 1.38 +/- 0.20 and 1.35 +/- 0.18 h for cyanidin-3,5-diglucoside, cyanidin-3-glucoside, cyanidin-3-sambubioside and total anthocyanins, respectively. The urinary excretion of intact anthocyanins was fast and the decline of excretion rates appeared to be monophasic, suggesting a one-compartment pharmacokinetic model, The low urinary excretion of dietary anthocyanidin glycosides with values below 1% indicates that a large proportion of these plant pigments consumed are metabolized before entry into the circulation.
Methotrexate (MTX)-induced acute lung injury developed in a female patient with rheumatoid arthritis. She was successfully treated with high-dose glucocorticoid therapy. During her hospital stay, the serum concentration of surfactant protein (SP)-D, which was markedly elevated on admission, was finally normalized and the disease resolved. However the serum concentration of Klebs von den Lungen (KL)-6 remained high. Although the mechanisms of lung injury by MTX have not been well defined, serial measurements of serum SP-D might be useful for the clinical evaluation of drug-induced acute lung injury.
Viscosuppplementation with intra-articular hyaluronic acid (hyaluronan [HA]) is a relatively new option for improving pain and articular function in patients with symptomatic knee osteoarthritis. An open multi-center study was performed in 365 patients with definite and symptomatic knee osteoarthritis from seven Latin American countries. Five doses of HA were administered once a week. The parameters studied were pain (six items), stiffness (two items) and functional capacity (17 items). The parameters were evaluated 1 week after the corresponding injection. Statistical differences were found when basal determinations of the three parameters were compared with the results of the first and fourth administration (p < 0.05). Intra-articular HA administration was well tolerated. Treatment-related nonserious adverse events were registered in 2.5% of administrations. Based on the results obtained, HA is a useful and well-tolerated symptomatic treatment for knee osteoarthritis with a rapid onset of action.
Biphosphonates, which are antiresorptive agents used to treat osteoporosis, inhibit the mevalonate pathway, preventing protein prenylation and inhibiting osteoclast activity. Statins decrease cholesterol biosynthesis by blocking the mevalonate pathway and have been reported to have beneficial effects on bone. D-003 is a mixture of high molecular weight acids purified from sugarcane wax that inhibits cholesterol biosynthesis before mevalonate production. D-003 prevents bone loss and resorption in rats with osteoporosis induced with ovariectomy or corticoids. Biochemical markers of bone turnover are used to monitor the short-term efficacy of antiosteoporotic therapy. This randomized, double-blind, placebo-controlled study was undertaken to investigate the short-term effects of D-003 (10 mg/day) on biochemical markers of bone turnover in postmenopausal women with low bone mineral density (BMD). After 4 weeks on a low-fat diet, 34 women were randomized to D-003 (10 mg/day) or placebo for 6 months. Pre- and post-treatment samples were analyzed for urinary excretion of deoxypyridinoline (DPD)/creatinine (Cr), a marker of bone resorption, and serum bone specific alkaline phosphatase (BSAP), a marker of bone formation. The effects on lipid profile and safety indicators, as well as adverse events (AE), were investigated. D-003 (10 mg/day) lowered urinary excretion of tDPD/Cr versus baseline (20.6%) (p < 0.001) and placebo (33.7%) (p < 0.01), but did not modify serum BSAP. D-003 decreased low-density lipoprotein-cholesterol (LDL-C) (32.8%), total cholesterol (TC) (16.4%) and the TC/high-density lipoprotein-cholesterol (HDL-C) ratio (34.7%), increased HDL-C (30.3%) (p < 0.001) and did not modify triglycerides. The effects on these variables were significant as early as 3 months after treatment initiation. D-003 was well tolerated. Three patients (one in the placebo group and two in the D-003 group) withdrew from the study. Two of these withdrawals were due to AE: abdominal pain (placebo) and heartburn (D-003). Five patients (four in the placebo group [22.2%] and one in the D-003 group [6.3%]) reported mild AE. In conclusion, D-003 (10 mg/day) reduced urinary excretion of tDPD/Cr, a bone resorption marker and did not change serum BSAP, a bone formation marker, while it lowered cholesterol in study patients. These preliminary results suggest that D-003 could be useful in treating postmenopausal women with low BMD. However, the potential value of D-003 in treating or preventing osteoporosis deserves further clinical investigation.
Psoriasis is a chronic debilitating cutaneous disorder that affects both sexes and appears clinically as inflamed, edematous skin lesions covered with a silvery white scale. Strong evidence suggests that immune mechanisms are implicated in its pathogenesis, such as persistent activation of T-lymphocytes, excessive proliferation of keratinocytes and reactivation of proto-oncogenes and other elements. Additionally, several recent studies have demonstrated that cytokines play a significant role in the pathogenesis of the disease, as they can be found in the affected skin of psoriatic patients. In this study we evaluated levels of circulating cytokines in the serum of 45 Greek psoriatic patients before initiation of treatment and compared the results with those in 45 healthy volunteers. According to our findings interleukin (IL)-2, IL-10, IL-12 and tumor necrosis factor-alpha (TNF-alpha) levels were statistically significantly elevated in the serum of psoriatic patients before therapy compared with those of controls. IL-6 serum levels did not differ between psoriatic patients and healthy volunteers. Conversely, interferon-gammaserum levels of psoriatic patients were statistically significantly lower than those of healthy volunteers.
Ranitidine has been found to have anti-inflammatory action as well as antisecretory action in experimental models. However, there are no reports in human gastric ulcer. The aim of this study was to investigate the effects of ranitidine compared with those of famotidine on the quality of gastric ulcer healing. We randomly assigned 69 consecutive patients with gastric ulcers to ranitidine (n = 34) or famotidine (n = 35) for 12 weeks, with endoscopic assessment of the quality of gastric ulcer healing and histological assessment of gastric mucosa 12 weeks after treatment started. Ulcer healing rates of over 95% were very similar in the two groups. The rates of ulcer scars with a flat pattern (good-quality healing) were significantly higher in the ranitidine group than in the famotidine group (per protocol, 63.0% and 34.5%, p = 0.033). The neutrophil infiltration score in the body mucosa treated with famotidine, but not ranitidine, significantly increased after treatment. In contrast, the mononuclear cell infiltration score in the antral mucosa treated with ranitidine, but not in that treated with famotidine, had significantly decreased. In conclusion, initial therapy with ranitidine significantly improved the quality of gastric ulcer healing and the histological scores of gastric mucosa compared with famotidine.
Psoriasis is a chronic inflammatory skin disorder Recent advances in the understanding of its immunological basis have led to its redefinition as being T-cell mediated. New biological agents have been developed as effective selective target therapies and promise to be an alternative to conventional systemic medications. Etanercept is a recombinant human protein recently approved for psoriatic arthritis treatment that has activity against tumor necrosis factor-alpha (TNF-alpha). It is composed of the human TNF receptor linked to the Fc portion of human IgG1. TNF-alpha seems to play a key role in the pathogenesis of psoriasis and psoriatic arthritis. Therefore,. etanercept TNF antagonism is an effective approach for severe psoriasis. We describe two case reports of severe recalcitrant psoriasis, also with arthritis, that showed a remarkable improvement with etanercept, with no adverse events.
We report a case of guttate psoriasis in a 28-year-old woman who had been suffering from scalp psoriasis from the age of 14. After an upper respiratory infection she presented with the typical exanthema of guttate psoriasis. Despite initial treatment with antibiotics and emollients, the rash continued to spread. Two months after the flare of psoriasis we decided to treat the patient with calcipotriol and betamethasone dipropionate ointment applied once daily, using an intermittent treatment modality. The lesions disappeared and despite two small recurrences on the legs we managed to maintain clearance after a 2-year follow-up. Although the application of calcipotriol and betamethasone dipropionate ointment was cumbersome, due to the extent of the eruption, the result was highly effective and safe without any lesional/perilesional adverse reaction during application and with normal blood examinations.
Patients receiving paclitaxel or docetaxel also receive a significant amount of ethanol, as both products contain ethanol as solvent. Patients in our clinics have occasionally exhibited signs of alcohol intoxication immediately after paclitaxel infusion. In 2002, the Japanese government lowered the minimum ethanol concentration for the definition of drunk driving, with the threshold breath alcohol concentration (BRAC) of 0.15 mg/l. The aim of this study was to measure BRAC in Japanese outpatients treated with paclitaxel or docetaxel and to assess intoxication according to this standard. Fifty-two Japanese patients were enrolled from October 2003 to February 2004. Patient characteristics were as follows: male/female, 13/39: median age, 71 (range: 34-78); breast/lung/ovarian cancer 24/16/12; and paclitaxel/docetaxel treatment: 36/16, respectively. The mean total doses of paclitaxel or docetaxel were 178 mg (range: 107-300) and 53 mg (30-100), respectively. Breath samples were measured three times immediately following the infusion of paclitaxel or docetaxel via ethyl alcohol detector and the mean value was recorded. BRAC was detected in 20 patients (56%) with paclitaxel and in none of the docetaxel patients. BRAC was measured again 30 min after the initial measurement in BRAC-detected cases with the patients' permission. In four of six BRAC-remeasured patients, BRAC became undetectable after 30 min. There was no correlation between the total doses of paclitaxel and BRAC or between the infusion rates of paclitaxel and BRAC. In conclusion, clinicians should recognize the potential for alcohol intoxication with paclitaxel administration. Patients should be instructed to avoid driving on the day of paclitaxel administration.
Bisphosphonates are a potential therapy for osteoclast-mediated bone disease, such as renal osteodystrophy. This study evaluated ibandronate bone-binding in patients with secondary hyperparathyroidism and renal osteodystrophy and examined whether there is a correlation with bone metabolism parameters. Sixteen patients with end-stage renal disease and secondary hyperparathyroidism receiving regular hemodialysis were recruited to this 12-week trial. Intravenous ibandronate 2 mg was administered for 5 min every 4 weeks directly after hemodialysis. Ibandronate levels were measured 15 min after infusion and at trough levels before the next hemodialysis. Serological markers of bone metabolism were also measured. After the first infusion, the peak ibandronate level was 154 +/- 75.1 ng/ml and the trough level was 2.7 +/- 1.7 ng/ml. At week 12, peak and trough ibandronate levels were 164.8 +/- 89.9 ng/ml and 3.2 +/- 2.6 ng/ml, respectively. Ibandronate bone uptake was 98.0% at first application and 98.4% at week 12. In patients with remaining diuresis, ibandronate urine excretion was < 0.001% of the administered dose. There was no correlation of ibandronate bone-binding with parameters of osteoclast activity or parathyroid hormone (PTH). The correlation with markers of osteoblast activity was significant but weak. Ibandronate had a bone-binding capacity of approximately 98% in hemodialysis patients. After repeated dosing ibandronate bone-uptake remained stable and was independent of osteoclast activity or PTH levels. Due to the high bone-binding of ibandronate in these patients, a 2 mg dose of intravenous ibandronate is equivalent to a 4-5 mg dose of ibandronate in patients with normal renal function.
TS-1 is a novel oral 5-fluorouracil containing tegaful (prodrug of 5-FU) and two biochemical modulators. These modulators feature effect-enhancing and adverse reaction-reducing activity. We investigated the histological response and toxicities of combination chemotherapy with TS- 1 and low-dose cisplatin and evaluated its usefulness as preoperative chemotherapy Forty-four newly diagnosed patients with stage Il-IV oral squamous cell carcinoma were enrolled in this study from February 2002 to April 2004. Patients were administered TS-1 80 mg/m2/day (days 1-14) and cisplatin 5 mg/m2/day (days 1-5 and 8-12) followed by radical surgery within 2 weeks. The histopathological effect of chemotherapy, which was a surrogate endpoint of this trial, was evaluated with surgical or biopsy specimens. The rate of histological antitumor effect was as follows: complete response (CR) 36.4%, partial response (PR) 25.0%, minor response (MR) 18.1% and no change (NC) 20.5%. The rate of histological response (CR + PR) was 61.4%. The CR rate of effective cases was 59.3%. The main toxicities occurred in bone marrow and the digestive tract. The incidence of severe toxicity such as grade 3 or 4 was 4.5% in anemia, 9% in leukocytopenia, 11.4% in neutropenia, 4.5% in thrombocytopenia and 2.3% in anorexia, diarrhea and urticaria. Most patients showed no toxicity or mild toxicities. TS- 1 with low-dose cisplatin has highly effective antitumor activity and mild toxicities. In particular, the CR rate was very high. It is suggested that this regimen is suitable for neoadjuvant chemotherapy. We expect that this chemotherapy will contribute to avoidance of surgery for small tumors (stages I and II) and will enable function-preserving surgery for advanced tumors.
A major component of genetic susceptibility to rheumatoid arthritis (RA) appears to be explained by inheritance of HLA-DRB1 alleles. Multiple HLA-DRB1 alleles (DRB1*0401, *0404, *0405, *0408, *0101, *102, *1001 and *1402) encoding a shared epitope at amino acid positions 70-74 are associated with susceptibility to RA. There is ethnic variation in the clinical expression of RA and in both the frequency and type of HLA-DRB1 alleles carrying the shared epitope. We evaluated the prevalence of the alleles of HLA-DRB1 locus encoding for SE in 42 outpatients with RA attending the Rheumatology Center of the University of Genoa, Bruzzone Institute, and living in Liguria. A control group was composed of Italian marrow donors. DNA genotyping was performed using a low-resolution polymerase chain reaction technique for characterization of the families of HLA-DRB1 alleles for each of the 42 patients studied. Subsequently, subjects with *01 and *04 haplotype were tested with high-resolution HLA-DRB 1 typing to characterize the *01 and *04 alleles. No statistically significant differences were found in the prevalence of RA-associated single alleles *01 and *04 in the study group or in the control group. In contrast, the sum of susceptibility *04 alleles studied by resolution typing was strongly related to RA in the study group in comparison with the control group.
The weight-loss efficacy of a novel, water-soluble, calcium-potassium salt of (-)-hydroxycitric acid (HCA-SX) was re-examined in 90 obese subjects (BMI: 30-50.8 kg/m2). We combined data from two previously reported randomized, double-blind, placebo-controlled clinical studies in order to achieve a better statistical evaluation based on a larger population. This re-examination of data also allowed us to reflect more intensely on various aspects of weight loss studies. Subjects were randomly divided into three groups: group A received a daily dose of HCA-SX 4, 667 mg (providing 2,800 mg HCA per day); group B was given a daily dose of a combination of HCA-SX 4,667 mg, niacin-bound chromium (NBC) 4 mg (providing 400 microg elemental chromium), and Gymnema sylvestre extract (GSE) 400 mg (providing 100 mg gymnemic acid); and group C received a placebo in three equally divided doses 30-60 min before each meal. All subjects were provided a 2,000 kcal diet/day and participated in a supervised walking program for 30 min/day, 5 days/week. Eighty-two subjects completed the study. At the end of 8 weeks, in group A, both body weight and BMI decreased by 5.4%, low-density lipoprotein and triglycerides levels were reduced by 12.9% and 6.9%, respectively, while high-density lipoprotein levels increased by 8.9%, serum leptin levels decreased by 38%, serotonin levels increased by 44.5% and urinary excretion of fat metabolites increased by 32-109%. Group B demonstrated similar beneficial changes, but generally to a greater extent. No significant adverse effects were observed. The combined results confirm that HCA-SX and, to a greater degree, the combination of HCA-SX plus NBC and GSE reduce body weight and BMI, suppress appetite, improve blood lipid profiles, increase serum leptin and serotonin levels and increase fat oxidation more than placebo. We conclude that dosage levels, timing of administration, subject compliance and bioavailability of HCA-SX significantly affect results and that when taken as directed, HCA-SX is a highly effective adjunct to healthy weight control.
Intestinal parasitic infections are major causes of childhood diseases in rural regions. The significant causes of this problem are the insufficient resources to improve the infrastructure in these regions and inadequate health services in both the diagnosis and treatment of diseases, The aim of this study was to assess the association between intestinal parasitic infections and clinical symptoms of infected children. Cellophane tape and stool samples of 100 children, aged between 7-10 years, from two villages of Manisa city, were examined for intestinal parasites and their symptoms were recorded. Although some symptoms, such as abdominal pain, anorexia and fatigue were found to be common in infected children, no significant relationship was found between symptoms and intestinal parasitic infections.
This retrospective study was carried out to evaluate the seropositivity of hepatitis B surface antigen (HbsAg), anti-hepatitis C virus (HCV), anti-human immunodeficiency virus (HIV) and syphilis in blood donors in Manisa Government Hospital. Data were evaluated in 10, 189 blood donors between April 1, 1997, which is the time from which regular records began to be collected, and April 1, 2003. The blood samples of the blood center from April 1, 1997, to January 1, 1998, were examined via the card method, those between January 1, 1998, and January 1, 2002, were examined via micro enzyme-linked immunosorbent assay (ELISA) method and the rest were evaluated with macro ELISA methods. In blood donors, the positivity of HbsAg, anti-HCV anti-HIV and the rapid plasmin reagin test were 2.95%, 0.68%, 0.00% and 0.16%, respectively.
Treatment of chronic hepatitis C virus (HCV) infection with interferon (IFN) and ribavirin improves the rate of eradication of the virus by less than 20% in patients with genotype 1b and a high viral load. In this study we assessed whether IFN-beta induction/IFN-alpha2b plus ribavirin enhances the efficacy of the therapy in patients with chronic hepatitis C. The efficacy of IFN-beta induction/IFN-alpha2b plus ribavirin therapy (group A, n=7) was compared with that of IFN-alpha2b plus ribavirin (group B, n=7) in 14 patients with high levels of HCV-RNA (> 100 K/U/ml). No significant differences were observed in the clearance of HCV-RNA between the two groups (A and B, respectively) 2 weeks after the start of the treatment (0% and 14.3%), at the end of the treatment (71.4% and 100%) and 6 months after the end of the treatment (28.6% and 14.3%). Recovery was complete in 28.6% and 14.3%, transient in 42.9% and 85.7% and absent in 28.6% and 0% in groups A and B, respectively. Early log changes in the viral load from the baseline after 2 weeks of treatment were 2.41 +/- 0.91 and 2.77 +/- 0.20 in groups A and B, respectively, with no significant difference between the two groups. In the present study, we were not able to demonstrate that IFN-beta induction/IFN-alpha2b plus ribavirin therapy was superior to IFN-alpha2b plus ribavirin therapy in patients with genotype 1b and high viral loads.
Several studies have demonstrated that matrix metalloproteinases (MMPs) are frequently implicated in the destruction of articular cartilage in arthritis. The control of MMP activity is dependent on the local concentration of tissue inhibitors of metalloproteinases (TIMPs), and the imbalance of the enzyme-to-inhibitor ratios plays an important role in the remodeling of articular tissues. Some cytokines such as interleukin (IL)-1 and tumor necrosis factor (TNF)-alpha which regulate leukocyte activities, promote MMP secretion and, as a consequence, cartilage degradation. The aim of the present study was to investigate whether a natural treatment is effective in reducing cartilage inflammation and degradation by influencing MMP and TIMP serum levels. Eighty patients with osteoarthritis (OA) were enrolled in the trial and were divided into group A (30 patients who did not undergo mud bath therapy), group B (28 patients repeating mud bath therapy more than 5 times and less than 10) and group C (22 patients repeating mud bath therapy more than 10 times). Blood samples were obtained from all the patients for assay of MMP-1, -2, -3, -8 and -9 and TIMP-1 and -2. The parameters were determined by an ELISA technique. Statistical indexes were calculated for each parameter and mean values were compared. The differences between mean values of MMP-3, -8 and -9 were statistically significant between group A and the treated groups (B and C). Analysis of variance established a significant difference (p < 0.05) between groups A and C in mean serum levels of MMP-8, MMP-9 showed a statistically significant difference (p < 0.05) in mean serum concentration between groups A and B. Regression analysis showed a very high R2 between MMP-2 and TIMP-2. One of the most interesting findings in this study was that MMP-3 serum levels were significantly lower in the treated groups, since this enzyme plays an important role in cartilage degradation, suggesting that mud bath therapy contributes to matrix integrity in OA cartilage. In contrast, MMP-8 and -9 were higher in the treated subjects and no correlation with TIMPs was evident. One possible explanation is that these enzymes are required for the efficient degradation and removal of already compromised cartilage matrix and that they operate as part of a matrix turnover and repair process. In conclusion, our data suggest that mud bath therapy alone is not able to influence chondrocyte metabolic activity in the advanced phases of OA. There could be a synergic and sequential association with pharmacologic therapy and/or interventions.
