Osteoarthritis is the most prevalent joint disease. Glucosamine sulphate has been widely used in humans to treat osteoarthritis for more than two decades, although there are not enough trials to confirm that glucosamine sulphate has therapeutic effect. Differential scanning calorimetry has been widely used for determining physicochemical transformations that occur during thermal degradation. The purpose of this study was to elucidate complex deviations that develop from the normal matrix composition during osteoarthritis and osteoarthritis with glucosamine sulphate treatment contributing to disease progression in monosodium iodoacetate osteoarthritis rat model. Osteoarthritis was induced by the intraarticular injection of monosodium iodoacetate. Glucosamine sulphate solution dissolved in water was administered to rats, two weeks after the monosodium iodoacetate injection. The control group received the same volume of distilled water. For sample preparation the rats were anesthetized and a 2 mm disc was removed from the unhealthy and healthy cartilage surfaces. The thermal properties of samples were determined by differential scanning calorimetry method. With the rise of temperature an endothermic reaction was observed in all cases. The enthalpy change of the process initiated by the temperature change showed marked difference (p<0.0001) between the normal and pathological groups. Interestingly the rats injected with monosodium iodoacetate and pretreated with oral glucosamine sulphate showed significantly higher increase in the value of the enthalpy change than the non-treated but osteoarthritis induced cartilage samples. Characterization of the altered metabolism in cartilage that promotes disease development should lead to future treatment options that can prevent structural damage. [ABSTRACT FROM AUTHOR]

Kobaltovi katalizatorji se v zadnjih letih vedno bolj uporabljajo za tvorbo vezi ogljik-ogljik. Prednost kobalta pred ostalimi prehodnimi kovinami je predvsem njegova dostopnost, nizka toksičnost ter nizka cena. Zaradi naštetih razlogov spadajo katalitski sistemi, ki kot katalizator uporabljajo kobaltove komplekse, med bolj ekološke. Reakcije z njimi potekajo v dokaj milih pogojih, za potek reakcije pa potrebujemo še bazo in ligand, s katerim kobalt tvori kompleks predhodno, ali pa in-situ. Tekom izdelave magistrske naloge smo sintetizirali nove derivate glukozamina kot ligande za katalitske sisteme. V teh sistemih z uporabo Grignardovih reagentov in s pomočjo kobalta in ligandov stereoselektivno tvorimo nove vezi ogljik-ogljik. Sintetizirali smo 8 potencialnih ligandov, od katerih smo nato tri uporabili v izbranem katalitskem sistemu. Sintetizirane spojine smo testirali tudi na encimih acetilholinesteraza, butirilholinesteraza in monoaminooksidaza A in B. Zaviralno aktivnost sta izkazovali dve spojini, in sicer na encimu butirilholinesteraza. Nazadnje smo ligandom določili tudi sposobnost kelacije nekaterih prehodnih kovin. Komplekse s kobaltom (Co2+) je tvorilo šest spojin, z železom (Fe2+) pa ena. Spojine, sposobne kelacije prehodnih kovin, se lahko potencialno uporabijo kot zdravilne učinkovine, kot kelatorji, ali pa kot učinkovine, kjer je prehodna kovina del zdravilne učinkovine in igra pri klinični aplikaciji ključno vlogo. Anorganska farmacevtska kemija je v uporabi sicer še vedno na drugem mestu za organsko kemijo, a številne raziskave v zadnjem desetletju dokazujejo njen potencial na številnih področjih medicine in farmacije. Sintetizirane derivate glukozamina smo tako uporabili za tri različne namene: - kot ligande v katalitskih sistemih, kjer smo tvorili nove vezi ogljik-ogljik - kot potencialne zaviralce encimov AChE, BChE, MAO-A in MAO-B - kot kelatorje nekaterih prehodnih kovin. Cobalt-based catalytic systems are being more widely used in the carbon-carbon bond formation. In comparison to some other transition metals, cobalt is easily accessible, has low toxicity and lower cost, which makes cobalt-based catalytic systems more eco-compatible and eco-friendly. Reactions take place under mild conditions. For the reaction to occur, a base and a ligand need to be added. The ligand forms a complex with the cobalt, either beforehand or in-situ. This Master's thesis is focused on the design of new glucosamine derivatives, to be used as ligands in catalytic systems, where carbon-carbon bonds were formed stereoselectively, using Grignard reagents and cobalt as a catalyst. We synthesised 8 potential ligands, of which three were used as ligands in the catalytic system. We tested the synthesised compounds on enzymes: acetylcholinesterase, butyrylcholinesterase, monoamino oxidase A and monoamino oxidase B. Two compounds showed inhibitory activity on butyrylcholinesterase. Lastly, we determined the ligands' chelating ability of certain transition metals. Six compounds formed complexes with cobalt (Co2+), whereas one compound formed complexes with iron (Fe2+). Compounds with chelating abilities can potentially be used as drugs – either as drugs that target metal ions in some form (chelators), or metal-based drugs, where the metal ion is crucial to the clinical application. Pharmaceutical industry is still dominated by drugs of organic origin, but numerous researches in the past decade have shown the potential of the medicinal inorganic chemistry. Synthesised glucosamine derivates can potentially be used as: - ligands in catalytic systems, where carbon-carbon bonds are formed - inhibitors for AChE, BChE, MAO-A and MAO-B - chelators of certain transitiona metals.

Artan yaşam süresiyle, osteoartrit dünya çapında yaygın bir sağlık problemidir. En sık görülen artrik şekli olup gittikçe önem kazanan hale gelmiştir. Bu hastalarda sürekli ağrı karakteristiktir ve ağrılı OA (Osteoartrit)'lı hastalar sıklıkla `alternatif` tedavi seçeneklerini denemeye teşebbüs ederler. Osteoartrit tedavisinde farmakolojik ve non farmakolojik birçok tedavi seçeneği vardır.Tıp bilimi hastayı korumak, yeniden sağlığına kavuşturmak ve acıdan kurtarmak için çalışır. Tüm bu hedeflere ulaşmak için ise ağrıyı tanımak gerekir. Ağrı hastaların doktora gitmesine neden olan en yaygın belirtidir. Ağrı ise vücudu korumayı ve dengeyi devam ettirmeyi hedefler. Ağrıyı bularak, konumlandırarak ve doku zedelendirmesini durdurarak bu işi yapar. Hastanın ağrı yakınmasının niteliği, zaman aralığı ve hassas bölgenin konumu teşhise yönelik önemli ipuçları verir. Fonksiyonel besinler sağlığımızın korunması ve geliştirilmesi açısından ilgi çeker hale gelmiştir. Temel besleyici özelliklerin ötesinde sağlığımıza olumlu katkıları olan besinlere fonksiyonel besin adı verilmektedir. Düzenli fonksiyonel besin olan Omega 3 ve Glukozamin tüketimi osteoperozun önlenmesinde etkili olduğu ve ağrı semptomlarının hafiflediği bilinmektedir. Çalışmamız toplamda 200 hasta ile çalışılmıştır. Fonksiyonel besin olan omega-3 ve glukozamin ağrı üzerinde etkisi hastalara görsel ağrı skalasında 1'den 10'a kadar değerlendirmesi istenilerek çalışmıiştır. Çalışma sonucunda omega-3 ve glukozamin kullanan hastalarda ağrıda anlamlı bir azalma olduğu gözlemlenmiştir.Anahtar Kelimeler: Glukozamin, Omega-3, Osteoartrit, Osteoporoz By the increasing of lifetime, osteoarthritis is a worldwide health problem. It is the most common arctic pattern and has become increasingly important. Patients with OA (Osteoarthritis) often attempt to try alternative treatment options. There are many pharmacological and non-pharmacological treatment options in the treatment of osteoarthritis. Medical science aims to protect the patient, restore health and save it from pain. In order to achieve all these goals, it is necessary to recognize the pain. Pain is the most common symptom that causes patients to go to the doctor. However pain tries to protect and maintain the balance of body. Medical science carries out by finding the pain, positioning it and stopping the tissue damage. The nature of the patient's pain complaint, time interval, and location of the sensitive area show important clues to diagnosis. Nutraceuticals have become of interest in the protection and development of our health. Beyond basic nutritive properties, nutrients that are positive contributors to human health are called nutraceuticals. It is known that consumption of Omega-3 and Glucosamine, which are regular nutraceuticals, is effective in preventing osteoporosis and relieves pain symptoms. Our study was conducted with a total of 200 patients. The effect of omega-3 and glucosamine on pain was studied by asking patients to evaluate 1 to 10 on visual pain scale. As a result of the study, a significant decrease in pain was observed in patients using omega-3 and glucosamine.Key Words: Glucosamine, Omega-3, Osteoarthritis, Osteoporosis, 58

Goal of osteoarthritis (OA) treatment is to relieve the pain and to reduce the loss of patient's physical functionality. Therapy consists of: nonpharmacological measures, pharmacotherapy and surgery. Although nonpharmacological approach represents a basis of OA treatment, pharmacotherapy is an important adjunct. Medications that are used in this disease can be administered orally, topically or intra-articularly. In OA treatment the following medications are used: analgesics, glucosamine- and chondroitin-based preparations, glucocorticoids and hyaluronic acid (intra-articular administration) and other medications. Nonopioid analgesics represent a corner stone in OA pharmacotherapy. Treatment initiation with paracetamol (acetaminophen) and/or topical nonsteroidal anti-inflammatory drug (NSAID) is recommended. Afterwards, in a case of complete or partial treatment failure, oral traditional NSAID (tNSAID) or selective COX-2 inhibitor should be used, or opioids as a substitute or an adjunct. Glucosamine- and chondroitin-based preparations are not recommended for OA treatment. Intra-articular use of glucocorticoid (triamcinolon) can lead to short lasting removal of pain and inflammation, while intra-articular use of hyaluronic acid is not recommended. Surgical treatment is important for heavy joint damage and in the case of failure of other treatment modalities. Cilj lečenja osteoartritisa (OA) je ublažiti bol i smanjiti gubitak fizičke funkcionalnosti pacijenta. Terapija se sastoji od: nefarmakoloških mera, farmakoterapije i hirurgije. Mada nefarmakološki pristup predstavlja osnovu lečenja OA, farmakoterapija je važan dodatak lečenju. Lekovi koji se primenjuju u ovoj bolesti mogu se davati per os, topikalno ili intraartikularno. U lečenju OA koriste se sledeći lekovi: analgetici, preparati na bazi glukozamina i hondroitina, glukokortikoidi i hijaluronska kiselina (intraartikularna primena) i ostali lekovi. Kamen temeljac u farmakoterapiji OA čine neopioidni analgetici. Preporučuje se otpočinjanje terapije paracetamolom i/ili topikalnim nesteroidnim antiinflamatornim lekom (NSAIL), nakon čega u slučaju potpunog ili delimičnog neuspeha treba primeniti oralne tradicionalne NSAIL/selektivne inhibitore ciklooksigenaze 2, ili opioide kao zamenu ili dodatak terapiji. Preparati na bazi glukozamina i hondroitina se ne preporučuju za lečenje OA. Intraartikularna primena glukokortikoida (triamcinolon) može da dovede do kratkotrajnog otklanjanja bola i inflamacije, dok se intraartikularna primena hijaluronske kiseline ne preporučuje. Hirurško lečenje je važno kod teških oštećenja zglobova u OA i neuspeha ostalih oblika lečenja.

Optimally balanced diet in order to body weight control in combination with adequate physical activity has an important role in the prevention of degenerative joint disorders. Weight reduction is important in ameliorating some of the manifestations of osteoarthritis (OA) and improving the quality of life. There is growing interest in the beneficial effects of some nutrients, especially polyunsaturated fatty acids and vitamin D, as well as many non-nutrient biological active compounds on progression structural damages, pain and functions of the joints. Glucosamine, chondroitin sulfate, S-adenosylmethionine, methylsulfonylmethane, alone or in combination, are among the most widely used dietary supplements for the prevention and treatment of OA. However, there are limited high-quality designed clinical trials which supported its potential symptomatic and structure-modifying effects. Optimalna ishrana u cilju održavanja idealne telesne mase uz odgovarajuću fizičku aktivnost ima značajnu ulogu u prevenciji degenerativnih oboljenja zglobova. Klinička ispitivanja su pokazala da gubitak povećane telesne mase smanjuje simptome i poboljšava kvalitet života pacijenata sa osteoartritisom (OA). Takođe, sve je veće interesovanje o uticaju pojedinih nutrijenata, posebno polinezasićenih masnih kiselina i vitamina D, kao i brojnih nenutritivnih biološki aktivnih sastojaka, na strukturna i funkcionalna oštećenja zglobova, kao i kontrolu bola kod OA. Najčešći sastojci dijetetskih suplemenata sa potencijalnim hondroprotektivnim delovanjem su: glukozamin, hondroitin-sulfat, S-adenozilmetionin, metilsulfonilmetan i dr, pojedinačno ili u kombinaciji. Međutim, ograničeni broj adekvatno dizajniranih randomizovanih kontrolisanih ispitivanja potvrdio je njihove simptomatske i strukturno modifikujuće efekte.

Osteoartrit (OA) eklemde ağrı, hareket kısıtlılığı, deformite ve tedavi edilmediği taktirde sakatlığa ve ölüme yol açabilen eklem hastalığıdır. Hastalığın seyrini değiştiren glukozamin (GA) ve kondroitin sülfat (KS)'ın eklem kıkırdağını besleyen sinovyal sıvıya nasıl ulaştığı ve etkisini nasıl gösterdiği az bilinir. Çalışmanın araştırma soruları; (1) Hyaluronik asit (HA) nanopartikül (nHA) şeklinde geliştirilerek eklem içinde kontrollü ilaç salım sistemi olarak kullanılabilir mi? (2) GA, nHA kullanılarak eklem içine taşınabilir mi? (3) GA'lar nHA'lardan kontrollü bir şekilde salınır mı? (4) GA-nHA hücre yapışması ve çoğalmasını arttırabilir mi? (5) GA-nHA'lar kemik iliği kaynaklı mezenkimal kök hücrelerin (Kİ-MKH) kıkırdak hücresine farklılaşmasına pozitif yönde etki eder mi? (6) GA-nHA'lar sağlıklı ve OA'lı insan kıkırdak hücrelerinin ekstraselüler matriks sentezini artırıp OA işaretlerini azaltır mı? nHA üretildikten sonra yapısal özellikleri Taramalı Elektron Mikroskobu (SEM), Dinamik Işık Saçılımı (DLS) ve Nükleer Manyetik Rezonans (¹H NMR) ile belirlenmiştir. nHA'ya GA ve KS bağlandıktan sonra bu moleküllerin salımı Yüksek Performanslı Sıvı Kromatografisi (HPLC) ile ölçülmüştür. KS'in nHA'dan salınmadığı görüldüğü için deneyler GA ile sürdürülmüştür. 1, 10 ve 100 µg/ml GAnHA'ların kondrosarkoma (SW-1353) hücreleri üzerindeki etkisi WST-1 hücre ii proliferasyon testi ile ölçülmüştür. GA-nHA'nın Kİ-MKH üzerindeki erken kondrojenik farklılaşma işaretlerinden SRY-Box-9 (SOX-9) ve kıkırdak oligomerik matriks proteini (COMP) ifadelerinin üzerine etkisini ölçmek için RT-PCR yapılmıştır. GA-nHA'ların sağlıklı ve OA'lı kondrositler üzerindeki ekstraselüler matriks işaretleri olan tip II kollajen (COL2A1) ve COMP üzerine etkisi ve OA işareti olan matriks metalloproteinaz-13 (MMP-13) üzerindeki etkisi ise yine RTPCR ile değerlendirilmiştir. ¹H NMR sonuçlarındaki 0.6-5.0 ppm arasındaki pikler nHA'ların başarılı bir şekilde sentezlendiğini, SEM ve DLS sonuçları ise partiküllerin 200-600 nm boyutları arasında homojen dağıldığını göstermektedir. HPLC ile ölçülen salım sonuçlarıyla GA'ların nHA'lardan 21 günde %20 oranında salım yaptığı belirlenmiştir. WST-1 proliferasyon testi sonuçlarına göre GA-nHA'nın üç dozu da hücre proliferasyonunu kontrol grubuna göre anlamlı olarak artırmamıştır. Ancak, GA'yı tek başına hücrelere uygulamanın kontrol grubuna göre anlamlı olarak proliferasyonu artırdığını göstermiştir. GA-nHA kondrojenik farklılaşma işaretleri olan SOX-9 ve COMP ifadesini anlamlı olarak değiştirmemiştir. OA'lı kondrositlerde 1 µg/ml GA-nHA MMP-13 seviyesini düşürmüş, 10 µg/ml GA-nHA uygulaması ise MMP-13 seviyesini düşürürken COMP ve COL2A1 seviyelerinde artışa neden olmuş ancak istatistiksel fark bulunmamıştır. Sağlıklı kondrositlerde ise üç dozda GA-nHA uygulaması kontrol grubu ile karşılaştırıldığında MMP-13 ifadesini baskılamış ancak bu da istatistiksel olarak anlamlı bulunmamıştır. Tek başına GA uygulandığında ise MMP-13 seviyesi anlamlı olarak düşmüş , farklılaşma işareti olan COMP seviyesini ise anlamlı olarak yükseltmiştir. Tek başına 10 µg/ml HA uygulaması sağlıklı kondrositlerin COMP ve COL2A1 seviyesinde artış sağlasa da yine kontrol grubu ile istatistiksel olarak anlamlı fark yoktur. GA-nHA'ların hücre proliferasyonuna ve Kİ-MKH'lerin kondrojenik farklılaşmasında bir etkisi olmamakla beraber OA'lı kondrositlerde MMP-13 ifadesini düşürdüğü, COMP ve COL2A1 seviyesini artırdığı görülmüştür. Sonuçlar istatistiksel olarak anlamlı olmasa da klinik olarak anlamlı olduğu düşünülmektedir. GA ve HA'yı tek başına uygulamalarda bazı olumlu sonuçlara ulaşmamız, GA-nHA'nın nanopartikül formunda hücrenin kullanamayacağı bir forma getirilmesinden kaynaklandığı düşünülmektedir. GA-nHA'ların OA tedavisinde etkili bir yöntem olup olmadığının belirlenebilmesi için hücre kültür ortamındaki dinamikleri, hücreye alım, hücrede işlenme mekanizmaları izlenmeli ve hücre kültüründeki etkileri uzun dönemde araştırılmalıdır. Osteoarthritis (OA) is a articular joint disease which causes pain, limitation of movement, deformity and can lead to disability and mortality. Glucosamine (GA) and chondroitin sulfate (CS) are alter the course of the disease but it is lesser known that how they are reach to the synovial fluid and show their effects. Research questions of this study whether (a) we could produce and use as a drug delivery system hyaluronic acid nanoparticles (nHA). (b) GA would transport to joint cavity using with nHAs. (c) GA-nHA would increase cell proliferation, (d) GAnHA would stimulate chondrogenesis of bone marrow mesenchymal stem cells (BM-MSC), and (e) GA-nHA would improve extracellular matrix (ECM) production and reduce OA markers of normal and osteoarthritic chondrocytes. After production of nHA's its structural property determined with SEM, DLS and ¹H NMR. After conjugating CS and GA to nHA's, release dynamics of these molecules determined with HPLC. CS didn't release from nHA's so studies contiuned with GA. Effects of 1, 10, 100 µg/ml GA-nHA's on chondrosarcoma cell line (SW-1353) measured by WST-1 Cell Proliferation Assay. Efficacy of early chondrogenic markers including cartilage oligomeric matrix protein (COMP) and SRY-Box-9 (SOX-9) expression on BM-MSCs of GA-nHAs measured by RT-PCR. Efficacy of extracellular matrix components including type II collagen (COL2A1) and COMP expression and OA marker matix metalloproteinase-13 (MMP-13) iv expression on healthy and osteoarthritic human chondrocytes of GA-nHAs mesaured by RT-PCR, again. Peaks between 0.6 and 5.0 ppm of ¹H NMR results showed that nHAs succesfully synthesised. SEM and DLS results showed particule size dispersed between 200 and 600 nm homogeneously. HPLC results showed us GA released in the ratio of 20% in 21 days. Three doses of GA-nHA's didin't increase proliferation of chondrosarcoma cells according to WST-1 Proliferation Assay outcomes. However, application of GA alone increased the proliferation significantly compare to control group. GA-nHAs did not significantly change the SOX-9 and COMP expressions. On OA chondrocytes, 1 µg/ml GA-nHA administration significantly decreased MMP-13 expression, 10 µg/ml GA-nHA administration decreased MMP-13 expression and incresed COMP and COL2A1 expressions, yet there is no significant difference was found. On healthy chondrocytes, three doses of GAnHA administration repressed the MMP-13 expression compared with the control group, but no significant changes were observed. When GA applied alone, MMP13 levels significantly decreased and chondrogenic marker COMP levels significantly increased compared with the control group. Also, 10 µg/ml HA group increased COMP and COL2A1 levels of healthy chondrocytes but there is no significant difference with control group. In conclusion, GA-nHAs did not effect cell proliferation and chondrogenic differentiation but decreased MMP-13 expression, increased COMP and COL2A1 expression of OA chondrocytes. Although these results are not statistically significant, they may be clinically significant. When we apply GA and HA alone, some of the positive results may be due to the fact that GA-nHA is in a form that cells can not use with nanoparticle form. In order to determine whether GA-nHAs is an effective method in the treatment of OA, the dynamics of cell culture medium, cellular uptake, cell processing mechanisms of GA-nHA should be monitored and long term effects of cell culture should be investigated. 97

WOS: 000315847100002 PubMed ID: 23588972 BACKGROUND The aim of this study is to determine whether glucosamine-sulfate has any effects on bone-healing. METHODS A unilateral fracture was created in the tibia of sixty-one female rats. Rats were given no drug or 230 mg/kg glucosamine- sulfate daily. Fractures were analyzed during the first, second and fourth weeks after creation of fracture. Quantitative measurement for new bone formation and osteoblast lining were determined histologically. Semiquantitative score for fracture healing was used for histomorphometric analyses. Bridging bone formation was assessed radiographically. RESULTS New bone formation and osteoblast lining were significantly higher in glucosamine-treated group at week 1. Surrounding connective tissue was more cellular and vascular, and the newly formed bone trabecules were present in greater amounts in glucosamine-treated group, compared to control group at week 1 and 4. But radiologically, the control group had better scores than that of the glucosamine- treated group at week 4. CONCLUSION These data demonstrate that daily glucosamine-sulfate administration accelerates early phase of fracture repair in the rat tibia, with increased new bone formation and osteoblast lining histologically, but radiologic bone union is not favored on radiographs. Bu çalışmanın amacı kıkırdak glukozaminin kırık iyileşmesi üzerinde etkisi olup olmadığının araştırılmasıdır. GEREÇ VE YÖNTEM Altmış bir dişi şıçan tibiasında tek taraflı kırık oluşturuldu. Sıçanlara ya 230 mg/kg glukozamin sülfat verildi ya da ilaç verilmedi. Kırıklar, kırık oluşumundan sonra birinci, ikinci ve dördüncü haftalarda incelendi. Yeni kemik oluşum miktarı ve osteoblast sayısı histolojik olarak ölçüldü. Histomorfometrik analiz için kırık iyileşmesi semikantitatif olarak skorlandı. Radyografik olarak kemik köprü oluşumu değerlendirildi. BULGULAR Glukozamin verilen grupta yeni kemik oluşumu ve osteoblast sayısı 1. haftada anlamlı derecede yüksekti. 1. ve 4. haftalarda kontrol grubuna göre, glukozamin verilen grupta çevre bağ dokusu hücre sayısı bakımından zengin, daha vasküler ve yeni oluşan kemik trabekülleri daha fazla sayıdaydı. Fakat radyolojik olarak 4. haftada kontrol grubu, glukozamin verilen gruptan daha iyi skorlar aldı. SONUÇ Bu veriler günlük glukozamin verilmesinin sıçan tibiasında kırık iyileşmesinin erken fazını, artmış yeni kemik oluşumu ve osteoblast sayısı ile histolojik olarak hızlandırdığı, fakat radyolojik olarak aynı etkinin görülmediğini göstermektedir

Takođe, sve je veće interesovanje o uticaju pojedinih nutrijenata, posebno polinezasićenih masnih kiselina i vitamina D, kao i brojnih nenutritivnih biološki aktivnih sastojaka, na strukturna i funkcionalna oštećenja zglobova, kao i kontrolu bola kod OA. Najčešći sastojci dijetetskih suplemenata sa potencijalnim hondroprotektivnim delovanjem su: glukozamin, hondroitin-sulfat, S-adenozilmetionin, metilsulfonilmetan i dr, pojedinačno ili u kombinaciji. Međutim, ograničeni broj adekvatno dizajniranih randomizovanih kontrolisanih ispitivanja potvrdio je njihove simptomatske i strukturno modifikujuće efekte.

- Abstract
Goal of osteoarthritis (OA) treatment is to relieve the pain and to reduce the loss of patient's physical functionality. Therapy consists of: nonpharmacological measures, pharmacotherapy and surgery. Although nonpharmacological approach represents a basis of OA treatment, pharmacotherapy is an important adjunct. Medications that are used in this disease can be administered orally, topically or intra-articularly. In OA treatment the following medications are used: analgesics, glucosamine- and chondroitin-based preparations, glucocorticoids and hyaluronic acid (intra-articular administration) and other medications. Nonopioid analgesics represent a corner stone in OA pharmacotherapy. Treatment initiation with paracetamol (acetaminophen) and/or topical nonsteroidal anti-inflammatory drug (NSAID) is recommended. Afterwards, in a case of complete or partial treatment failure, oral traditional NSAID (tNSAID) or selective COX-2 inhibitor should be used, or opioids as a substitute or an adjunct. Glucosamine- and chondroitin-based preparations are not recommended for OA treatment. Intra-articular use of glucocorticoid (triamcinolon) can lead to short lasting removal of pain and inflammation, while intra-articular use of hyaluronic acid is not recommended. Surgical treatment is important for heavy joint damage and in the case of failure of other treatment modalities., Cilj lečenja osteoartritisa (OA) je ublažiti bol i smanjiti gubitak fizičke funkcionalnosti pacijenta. Terapija se sastoji od: nefarmakoloških mera, farmakoterapije i hirurgije. Mada nefarmakološki pristup predstavlja osnovu lečenja OA, farmakoterapija je važan dodatak lečenju. Lekovi koji se primenjuju u ovoj bolesti mogu se davati per os, topikalno ili intraartikularno. U lečenju OA koriste se sledeći lekovi: analgetici, preparati na bazi glukozamina i hondroitina, glukokortikoidi i hijaluronska kiselina (intraartikularna primena) i ostali lekovi. Kamen temeljac u farmakoterapiji OA čine neopioidni analgetici. Preporučuje se otpočinjanje terapije paracetamolom i/ili topikalnim nesteroidnim antiinflamatornim lekom (NSAIL), nakon čega u slučaju potpunog ili delimičnog neuspeha treba primeniti oralne tradicionalne NSAIL/selektivne inhibitore ciklooksigenaze 2, ili opioide kao zamenu ili dodatak terapiji. Preparati na bazi glukozamina i hondroitina se ne preporučuju za lečenje OA. Intraartikularna primena glukokortikoida (triamcinolon) može da dovede do kratkotrajnog otklanjanja bola i inflamacije, dok se intraartikularna primena hijaluronske kiseline ne preporučuje. Hirurško lečenje je važno kod teških oštećenja zglobova u OA i neuspeha ostalih oblika lečenja.

- Abstract
Cilj ove disertacije je bio da se ispita i utvrdi simptomatski i strukturalni efekat primene kristalnog glukozamin sulfata (KGS) (1.5 g/dan) kod osteoartroze kolena. Primena KGS je upoređivana u odnosu na nesteroidne antiinflamatorne lekove (NSAIL) (ibuprofen 1200-1600 mg/dan; diklofenak natrijum 75mg/dan). U otvorenu, prospektivnu studiju sa periodom praćenja od godinu dana, je uključeno 111 ambulatnih bolesnika oba pola, starosti ≥55 godina. Istraživanje je sprovedeno u Specijalnoj bolnici za reumatske bolesti u Novom Sadu u periodu od 2011.-2013. godine. Do kraja je u studiji ostalo 80 bolesnika. Bolesnici su dolazili na zakazane kontrole nakon 1.,3.,6.,9. i 12. meseca (5 kontrola). Procena terapijskog efekta je praćena pomoću kliničkih (WOMAC index i Lequesne index) i strukturalnih parametara bolesti (radiološko merenje širine zglobnog prostora u medijalnom kompartmanu tibiofemoralanog zgloba kolena). Nakon 1. meseca kod bolesnika NSAIL grupe je registrovano statistički značajnije smanjenje bola i ukočenosti i poboljšanje funkcije (p<0.05). Za isti period obe grupe bolesnika su imale niži Lequesne indeks, bez statistički značajne razlike (p>0.05). Nakon 3. meseca kod bolesnika KGS grupe i bolesnika NSAIL je registrovano ublažavanje simptoma bolesti, bez statistički značajne razlike (p>0.05). Nakon 6. meseca, primena KGS je dovela do značajnijeg smanjenja bola, poboljšanja funkcije zgloba i smanjenja Lequesne indeksa (p<0.01). Daljom primenom KGS nastavljen je trend smanjenja simptoma bolesti. Na kraju istraživanja bolesnici KGS grupe su imali statistički značajnije smanjenje bola, poboljšanje funkcije (WOMAC bol, WOMAC funkcionalni status i ukupan WOMAC zbira) (p<0.01) i poboljšanje simptoma praćenih pomoću Lequene indeksa u odnosu na bolesnike NSAIL grupe (p>0.05). U periodu prekida uzimanja KGS (početak 7. do kraja 9. meseca) kod bolesnika je registrovano pogoršanje simptoma bolesti u odnosu na prethodnu kotrolu, ali je tokom 1. meseca prekida uzimanja KGS (7., The aim of this thesis was to research and ablish symptomatic and struc - tural effect of crystalline glucosamine sulfate (CGS) (1.5 g/day) in knee osteoarthrosis. CGS treatment was compared to nonsteroid anti-inflammatory drugs (NSAID) (ibuprofen 1200- 1600 mg/day; diclofenac sodium 75 mg/day). The open, prospective studyStudy was carried out in the Special hospital for rheumatic diseases in Novi Sad, during 2011-2013 period with one year fol- low-up included 111 outpatients of both genders, 55 years of age or morEighty patients had completed the study. Every patient had checkups scheduled after 1, 3, 6, 9and 12 months (5 checkups total). Assessment of therapy effect has been done using clinical (WOMAC index and Lequesne index) and structural parameters of the disease (radiologic measurements of joint space width at the medial compartment in tibiofemoral knee joint) .Af- ter one month, a statistically significant reduction of pain and stiffness with improvement of joint function (p<0.05) was noted in patients from NSAID group. In this period, both groups had lower Lequesne index, without statistical significance (p>0.05). After 3 months, in both groups (CGS and NSAID patients), symptoms improvement was noted without statistically significant differences (p>0.05). After 6 months, CGS brought significant pain reduction im -provement of joint function and decrease in Lequesne index (p<0.01). Further treatment by CGS continued to reduce symptoms of the disease. At the end of trial, patients from CGS group had statistically more significant pain reduction, function improvement (WOMAC pain, WOMAC functional status and total WOMAC score) (p<0.01) and symptoms improve- ments measured by Lequesne index in comparison to patients from NSAID group (p>0.05). In the period of pause in CGS treatment (months 7 to 9), worsening of symptoms has been noted in patients in comparison to previous checkup, but during the first month of pause (sev- enth month of trial) prolong
