Combined chondroitin sulfate and glucosamine for painful knee osteoarthritis: a multicentre, randomised, double-blind, non-inferiority trial versus celecoxib.
    Annals of the rheumatic diseases, 2016, Volume: 75, Issue:1

    To compare the efficacy and safety of chondroitin sulfate plus glucosamine hydrochloride (CS+GH) versus celecoxib in patients with knee osteoarthritis and severe pain.. Double-blind Multicentre Osteoarthritis interVEntion trial with SYSADOA (MOVES) conducted in France, Germany, Poland and Spain evaluating treatment with CS+GH versus celecoxib in 606 patients with Kellgren and Lawrence grades 2-3 knee osteoarthritis and moderate-to-severe pain (Western Ontario and McMaster osteoarthritis index (WOMAC) score ≥301; 0-500 scale). Patients were randomised to receive 400 mg CS plus 500 mg GH three times a day or 200 mg celecoxib every day for 6 months. The primary outcome was the mean decrease in WOMAC pain from baseline to 6 months. Secondary outcomes included WOMAC function and stiffness, visual analogue scale for pain, presence of joint swelling/effusion, rescue medication consumption, Outcome Measures in Rheumatology Clinical Trials and Osteoarthritis Research Society International (OMERACT-OARSI) criteria and EuroQoL-5D.. The adjusted mean change (95% CI) in WOMAC pain was -185.7 (-200.3 to -171.1) (50.1% decrease) with CS+GH and -186.8 (-201.7 to -171.9) (50.2% decrease) with celecoxib, meeting the non-inferiority margin of -40: -1.11 (-22.0 to 19.8; p=0.92). All sensitivity analyses were consistent with that result. At 6 months, 79.7% of patients in the combination group and 79.2% in the celecoxib group fulfilled OMERACT-OARSI criteria. Both groups elicited a reduction >50% in the presence of joint swelling; a similar reduction was seen for effusion. No differences were observed for the other secondary outcomes. Adverse events were low and similarly distributed between groups.. CS+GH has comparable efficacy to celecoxib in reducing pain, stiffness, functional limitation and joint swelling/effusion after 6 months in patients with painful knee osteoarthritis, with a good safety profile.. NCT01425853.

Effect of Chondroitin Sulfate on Blood Serum Cytokine Profile during Carrageenan-induced Edema and Monoiodoacetate-induced Osteoarthritis in Rats.
    Reviews on recent clinical trials, 2019, Volume: 14, Issue:1

    Blood cytokines affect the development of inflammatory processes in both normal and pathological states. We have studied changes in the concentration of interleukins (ILs) - 1β, IL-4, IL-10, IL-12B p40, transforming growth factor β (TGF β), tumor necrosis factor (TNF-α) in acute carrageenan-induced inflammation and degenerative-dystrophic changes of knee joint caused by monoiodoacetate-induced Osteoarthritis (OA) in experimental models on rats. We also investigated the change in the cytokine profile during prophylactic and therapeutic administration of chondroitin sulfate to animals under experimental conditions.. The concentration of the cytokines was measured in blood serum by enzyme-linked immunosorbent assay.. The manifestation of articular lesions was characterized by a disturbance in the balance between proinflammatory (IL-1β, IL-12B p40, TNF-α) and anti-inflammatory (IL-4, IL-10, TGF -β) cytokines.. A reduction in the concentration of proinflammatory cytokines in blood serum after prophylactic and therapeutic administration of chondroitin sulfate to the rat with experimental models of acute inflammation of the hind limb and degenerative-dystrophic changes in the knee joint with OA is associated with anti-inflammatory and regenerative properties of the drug.

Occurrence of sulfated fucose branches in fucosylated chondroitin sulfate are essential for the polysaccharide effect preventing muscle damage induced by toxins and crude venom from Bothrops jararacussu snake.
    Toxicon : official journal of the International Society on Toxinology, 2015, Volume: 98

    Snake envenoming is an important public health problem around the world, particularly in tropics. Beyond deaths, morbidity induced by snake venoms, such as myotoxicity, is of pivotal consequence to population. Bothrops jararacussu is the main venomous snake in southeast region of Brazil, and particularly presents strong myotoxic effect. The only available therapy, antibothropic antivenom, poorly affects venom-induced myotoxicity. The aim of this study is to assess the ability of fucosylated chondroitin sulfate (fucCS), a glycosaminoglycan with anticoagulant and antithrombotic properties, and its derivatives to inhibit toxic activities of B. jararacussu crude venom and its isolated toxins, named bothropstoxins (BthTX-I and BthTX-II). The in vitro myotoxic activities induced by crude venom, by BthTX-I alone and by toxins together were abolished by fucCS. Carboxyl reduction (fucCS-CR) kept this ability whereas defucosilation (defucCS) abrogates myoprotection. We observed the same pattern in the response of these polysaccharides in antagonizing the increase in plasma creatine kinase (CK) levels, the reduction of skeletal muscle CK content and the rise of myeloperoxidase (MPO) activity induced by crude venom and isolated toxins. FucCS inhibited edematogenic activity and partially prevented the reduction of total leukocytes in blood when pre-incubated with crude venom. Furthermore, the venom procoagulant effect was completely antagonized by increasing concentrations of fucCS, although this polyanion could stop neither the tail bleeding nor the skin hemorrhage induced by Bothrops jararaca venom. The B. jararacussu phospholipase, hyaluronidase, proteolytic and collagenase activities were inhibited in vitro. The results suggest that fucCS could be able to interact with both toxins, and it is able to inhibit BthTX-II phospholipase activity. Light microscopy of extensor digitorum longus muscle (EDL) muscle showed myoprotection by fucCS, once necrotic areas, edema and inflammatory cells were all decreased as compared to venom injection alone. Altogether, data show that fucCS was able to inhibit myotoxicity and inflammation induced by B. jararacussu venom and its phospholipase toxins, BthTX-I and BthTX-II. Thus, fucosylated chondroitin sulfate is a new polyanion with potential to be used as an adjuvant in the treatment of snakebites in the future.

Intravesical chondroitin sulfate inhibits recruitment of inflammatory cells in an acute acid damage "leaky bladder" model of cystitis.
    Urology, 2012, Volume: 79, Issue:2

    To investigate whether a physiologic effect of "glycosaminoglycan (GAG) replenishment therapy" altered recruitment of inflammatory cells in an acute bladder damage model. Replacement of the GAG layer with intravesically administered GAGs is an effective therapy for interstitial cystitis in at least some patients. Intravesically administered chondroitin sulfate was previously shown to bind to and restore the impermeability of surface-damaged ("leaky") urothelium to small ions.. Rat bladders were damaged with 10 mM HCl. Negative control bladders were treated with phosphate-buffered saline. On the following day, the animal bladders were treated with 20 mg/mL chondroitin sulfate in phosphate-buffered saline, and the negative and positive controls were treated with phosphate-buffered saline alone. At 2 and 4 days after treatment with chondroitin sulfate, the rats were killed, and sections of their bladders were analyzed using toluidine blue staining for mast cell immunohistochemical labeling using antibodies against CD45 for lymphocytes and myeloperoxidase for neutrophils.. Chondroitin sulfate treatment reduced the recruitment, in a statistically significant manner, of inflammatory cells, including neutrophils and mast cells to the suburothelial space but did not alter recruitment of CD45-positive lymphocytes.. For the first time, we have demonstrated that intravesical GAG replenishment therapy also produces a physiologic effect of decreasing recruitment of inflammatory cells in an acute model of the damaged bladder. These findings support the use of intravesically administered GAG for bladder disorders that result from a loss of impermeability, including interstitial, radiation, and chemical cystitis, and possibly others as well.

Outbreak of adverse reactions associated with contaminated heparin.
    The New England journal of medicine, 2008, Dec-18, Volume: 359, Issue:25

    In January 2008, the Centers for Disease Control and Prevention began a nationwide investigation of severe adverse reactions that were first detected in a single hemodialysis facility. Preliminary findings suggested that heparin was a possible cause of the reactions.. Information on clinical manifestations and on exposure was collected for patients who had signs and symptoms that were consistent with an allergic-type reaction after November 1, 2007. Twenty-one dialysis facilities that reported reactions and 23 facilities that reported no reactions were included in a case-control study to identify facility-level risk factors. Unopened heparin vials from facilities that reported reactions were tested for contaminants.. A total of 152 adverse reactions associated with heparin were identified in 113 patients from 13 states from November 19, 2007, through January 31, 2008. The use of heparin manufactured by Baxter Healthcare was the factor most strongly associated with reactions (present in 100.0% of case facilities vs. 4.3% of control facilities, P<0.001). Vials of heparin manufactured by Baxter from facilities that reported reactions contained a contaminant identified as oversulfated chondroitin sulfate (OSCS). Adverse reactions to the OSCS-contaminated heparin were often characterized by hypotension, nausea, and shortness of breath occurring within 30 minutes after administration. Of 130 reactions for which information on the heparin lot was available, 128 (98.5%) occurred in a facility that had OSCS-contaminated heparin on the premises. Of 54 reactions for which the lot number of administered heparin was known, 52 (96.3%) occurred after the administration of OSCS-contaminated heparin.. Heparin contaminated with OSCS was epidemiologically linked to adverse reactions in this nationwide outbreak. The reported clinical features of many of the cases further support the conclusion that contamination of heparin with OSCS was the cause of the outbreak.

Chondroitin sulfate intake inhibits the IgE-mediated allergic response by down-regulating Th2 responses in mice.
    The Journal of biological chemistry, 2006, Jul-21, Volume: 281, Issue:29

    Chondroitin sulfate (CS) was administered orally to BALB/c mice immunized intraperitoneally with ovalbumin (OVA) and/or dinitrophenylated OVA. The titers of antigen-specific IgE and IgG1 in mouse sera were determined. The antigen-specific IgE production by mice fed ad libitum with CS was significantly inhibited. We also examined the effect of feeding CS on immediate-type hypersensitivity. One hour after antigen stimulation, the ears of mice fed with CS swelled less than those of the control mice. Furthermore, the rise in serum histamine in the mice fed with CS under active systemic anaphylaxis was significantly lower than that in the controls. We next examined the pattern of cytokine production by splenocytes from mice followed by re-stimulation with OVA in vitro. The splenocytes from the mice fed with CS produced less interleukin (IL)-5, IL-10, and IL-13 than those from the control group. In contrast, the production of interferon-gamma and IL-2 by the splenocytes of mice fed with CS was not significantly different from those in the control mice. In addition, the production of transforming growth factor-beta from the splenocytes of mice fed with CS was significantly higher than that of the control mice. Furthermore, we showed that the percentages of CD4(+) cells, CD8(+) cells, and CD4(+)CD25(+) cells in the splenocytes of mice fed with CS are significantly higher than those of the control. These findings suggest that oral intake of CS inhibits the specific IgE production and antigen-induced anaphylactic response by up-regulating regulatory T-cell differentiation, followed by down-regulating the Th2 response.

Chondroitin sulfate-based anti-inflammatory macromolecular prodrugs.
    European journal of pharmaceutical sciences : official journal of the European Federation for Pharmaceutical Sciences, 2006, Volume: 29, Issue:1

    Macromolecular prodrugs of three non-steroidal anti-inflammatory drugs (NSAIDs), ibuprofen, ketoprofen, and naproxen, were prepared by the covalent attachment of the drugs onto chondroitin sulfate (ChS) using PEG 1000 as a spacer. Drug-PEG adducts were synthesized using 1,1'-carbonyl diimidazole as a coupling agent in dimethyl sulfoxide, followed by the reaction with ChS in highly dilute aqueous solution at pH 6.8 via N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDAC) as a conjugation agent. The drug-ChS conjugates were confirmed by FTIR, 1H NMR and 13C NMR and the molar percent of drug substitution onto ChS was characterized by 1H NMR using the peak areas of the three protons of -PhiCHCH3 on the drugs to those of -NHCOCH3 on ChS. All drug-ChS conjugates are water-soluble. The release amounts of the free drugs from their corresponding drug-ChS conjugates were evaluated in the presence or absence of either esterase or chondroitinase, and the both enzymes in pH 7.4 Tris-buffer solutions at 37 degrees C by high performance liquid chromatography (HPLC). Keto-ChS conjugates released approximately 100% ketoprofen within 12h in the presence of esterase, but the combination with chondroitinase did not accelerate the release rate. The degradation of Keto-ChS conjugates by chondroitinase was confirmed by gel permeation chromatography (GPC). The Keto-ChS conjugates still retained the enzymatic recognition even at the substitution of ketoprofen as high as 56 mol%. The inhibition percent of carrageenan-induced edema of Keto-ChS-56 was comparable to that of a simple blend of ChS and ketoprofen, suggesting that biologically active ChS and ketoprofen could be liberated from the conjugate.

Effects of low molecular weight chondroitin sulfate on type II collagen-induced arthritis in DBA/1J mice.
    Biological & pharmaceutical bulletin, 2004, Volume: 27, Issue:1

    In order to evaluate the improvement in the treatment of chronic arthritis, we investigated chondroitin sulfate depolymerization product (low molecular weight chondroitin sulfate, LMWCS) and intact chondroitin sulfate (CS) in vitro and in vivo. LMWCS was prepared by a chemical depolymerization process induced by hydrogen peroxide in the presence of copper salts. LMWCS (300 mg/kg) and CS (1200 mg/kg) were orally administered to DBA/1J mice once daily for 14 d prior to initial immunization with type II collagen. Their elastase activities and the production of cytokines in sera were examined on type II collagen-induced arthritis in DBA/1J mice. We also compared the paracellular transport of LMWCS and CS across Caco-2 cell monolayers and examined the inhibitory effects on elastase activities. LMWCS inhibited elastase activity slightly, but CS did not show inhibition. Hind paw edema was significantly decreased by LMWCS treatment. Levels of anti-type II collagen antibody and tumor necrosis factor-alpha (TNF-alpha) in sera were also reduced by LMWCS treatment but not in case of CS, although no significant difference was observed between LMWCS and CS on interleukin-6 (IL-6) induction. The LMWCS preparation showed preventive effects on the type II collagen-induced arthritis in DBA/1J mice and better permeability through Caco-2 cells.

Administration of hyaluronic acid and chondroitin-4-sulfate limits endogenous antioxidant depletion and reduces cell damage in experimental acute pancreatitis.
    Pancreas, 2004, Volume: 28, Issue:2

    Several reports have described a loss of endogenous antioxidants and molecular oxidative damage during acute pancreatitis. Since hyaluronic acid and chondroitin-4-sulfate possess antioxidant properties, the effect of the administration of these glycosaminoglycans in a cerulein-induced acute pancreatitis in rats was investigated. Cerulein administration produced pancreatic edema and a marked increase in serum lipase and amylase activity; induced a severe depletion of reduced glutathione, catalase, and superoxide dismutase levels; primed lipid peroxidation; and promoted neutrophil intervention. Intraperitoneal pretreatment of rats with hyaluronic acid or chondroitin-4-sulfate or with both compounds ameliorated pancreatic cell conditions; restored the endogenous antioxidants reduced glutathione, catalase and superoxide dismutase; limited cell membrane peroxidation; and reduced neutrophil activation. Our data confirm the antioxidant activity of these 2 glycosaminoglycans.

Effects of chondroitin sulfate-C on articular cartilage destruction in murine collagen-induced arthritis.
    Arzneimittel-Forschung, 2000, Volume: 50, Issue:2

    The effects of chondroitin sulfate-C (CAS 25322-46-7, Chondroitin ZS Tab) on type II collagen (CII)-induced arthritis (CIA) in mice were evaluated. DBA/1J mice were immunized with bovine CII emulsified in Freund's complete adjuvant, followed by a booster injection 21 days later. Chondroitin sulfate-C at doses of 100, 300 and 1000 mg/kg was administered orally once daily beginning 14 days before initial immunization. An arthritis index and hind paw edema were examined from day 0 to day 49, when the mice were killed by ether anesthesia for histopathological examination. The delayed-type hypersensitivity (DTH) reaction, serum anti-CII antibody titer, and histopathologic characteristics of both synovitis and destruction of articular cartilage were analyzed. Both the arthritis index and the serum anti-CII antibody titer were reduced by treatment with chondroitin sulfate-C in a dose-dependent manner. Chondroitin sulfate-C (1000 mg/kg) significantly inhibited hind paw edema, synovitis and destruction of the articular cartilage, but not DTH reaction.

Ultrastructural and histochemical features of the ground substance in cyclosporin A-induced gingival overgrowth.
    Journal of periodontology, 1996, Volume: 67, Issue:1

    The overgrowth-affected gingiva of patients treated with cyclosporin A after kidney transplant was examined with ultrastructural and histochemical methods to evaluate the involvement of connective tissue. Gingival overgrowth has the same clinical signs as local edema. The ultrastructural study showed that the dimensional increase was largely due to increased production of amorphous ground substance by fibroblasts, possibly resulting from an increased release of histamine by mast cells. The histochemical data revealed that the affected tissues contained higher levels of glycosaminoglycans and that cyclosporin A induced comparably high levels of glycosaminoglycans in in vitro cultures of fibroblasts obtained from normal gingiva. The combination of ultrastructural and histochemical data, therefore, strongly suggests that the response of the connective tissue in gingival overgrowth cannot be ignored and may be the main cause of the observed pathological condition.

Heparin, a potent releasing agent of extracellular superoxide dismutase (EC-SOD C), suppresses ischaemic paw oedema in mice.
    Free radical research communications, 1990, Volume: 9, Issue:2

    Heparin (2,000 U/kg, i.v.) increases the plasma superoxide dismutase (SOD) activity by 2-3 times after 5 min. followed by a gradual decrease. A high dose of heparin (4 x 10(3) and 10 x 10(3) U/kg) exhibits a lower increase in the release of SOD. Ischaemic paw oedema in mice was suppressed by various types of SOD and heparin also suppresses this oedema. The dose-dependent curve of heparin of oedema suppression corresponds well with the increased plasma level of SOD. Inducibility with heparin, slow clearance from the bloodstream and blocking of oedema suppression by the copper chelator, diethyldithiocarbamate (DDC), suggest that the oedema suppressing SOD was the extracellular (EC)-SOD C. Other anticoagulants such as citrate and EDTA had no effect. Chondroitin sulphate A and C or carrageenan exhibited weak suppression. A complex of EC-SOD C and heparin appears not to bind to the endothelium in contrast to the injected free EC-SOD C. When heparin is re-injected, more than 1 week was required to get the same degree of oedema suppression. This indicates the necessity of newly synthesized enzyme. A biological role for heparin-induced release of plasma SOD is demonstrated for the first time in this investigation.

Development of the biochemical and morphological changes induced by administration of a beta-xyloside to chick embryos.
    Teratology, 1982, Volume: 25, Issue:1

    4-Methylumbelliferyl beta-D-xyloside was administered to 9-day-old chick embryos, and the morphological and chemical changes in the embryo were followed daily. Increases in wet weight, Na and Cl content, and visible edema were detectable at 10 days and fully apparent at 11 days. Dry weight increased to the same extent in control and treated embryos for four days, but then diverged. The degree of sulfation of chondroitin sulfate was slightly less in treated than control embryos at 10 days, and reached a steady low value at 11 days. Analysis of glycosaminoglycans in skin, muscle, and aorta showed an increase in chondroitin and its sulfates in the two former tissues but not the latter. In muscle and aorta, the degree of sulfation of chondroitin sulfate was markedly reduced; but in skin the results suggested a more complex picture in which the normal metabolism of glycosaminoglycans was altered. A possible physiological role is suggested for chondroitin sulfate in embryonic soft tissues.
