"Latar belakang: Sumsum tulang merah merupakan sumber utama sel punca mesenkim walaupun penggunaannya menimbulkan morbiditas situs donor. Pengambilan sel punca dari sumsum tulang menyebabkan nyeri dan seringkali sukar dilakukan sehingga membutuhkan sumber alternatif. Karena penyembuhan tulang sekunder terjadi melalui pembentukan kalus hasil proliferasi dan diferensiasi sel punca, kalus mungkin menjadi sumber alternatif pengambilan sel punca mesenkim. Penelitian ini membandingkan jumlah plastic-adherent cells dari kalus dan sumsum tulang setelah dua minggu kultur sel.Metode: Enam belas kelinci Selandia Baru dilakukan prosedur frakturisasi diafisis tulang femur. Lalu, seluruh kelinci dirawat. Selanjutnya, dua minggu pasca-frakturisasi, 3 mL aspirasi sumsum tulang krista iliaka dan ekstraksi kalus situs fraktur pada delapan kelinci dilakukan kultur (kelompok I). Delapan kelinci lainnya dilakukan hal yang sama pada empat minggu pasca-frakturisasi (kelompok II). Seluruh kultur diamati setelah satu dan dua minggu. Setelah empat minggu, kultur dipanen. Jumlah sel dihitung dengan hemositometer Neubauer. Kemudian, perbandingan jumlah sel dianalisis menggunakan uji t tidak berpasangan.Hasil: Pada kelompok I terdapat jumlah sel sebanyak 2,6 ± 0,1 x 104 untuk kultur aspirat sumsum tulang krista iliaka dan 2,5 ± 0,1 x 104 untuk kultur ekstraksi kalus situs fraktur. Tidak terdapat perbedaan bermakna secara statistik antara keduanya (p = 0,34). Sedangkan pada kelompok II didapatkan hasil sebesar 2,7 ± 0,1 x 104 sel dan 2,1 ± 0,1 x 104 sel secara berurutan dan terdapat perbedaan yang bermakna secara statistik antara keduanya (p < 0,001).Kesimpulan: Situs kalus fraktur dua minggu pasca-frakturisasi memiliki potensi sebagai situs donor untuk isolasi dan ekspansi plastic-adherent cells.

Background: Red marrow has been described as the main source of mesenchymal stem cells although its aspiration and isolation from bone marrow was reported to have significant donor site morbidity. Since secondary bone healing occurs through formation of callus as the result of proliferation and differentiation of mesenchymal stem cells, callus may become alternative source for mesenchymal stem cells. In this study, we compared the number of plastic-adherent cells from fracture site callus and bone marrow of iliac crest after two and four weeks of culture.

Methods: Sixteen New Zealand rabbits were fracturized at the femoral shaft. Then, these rabbits were taken care. After two weeks of fracturization, 3 mL iliac crest bone marrow aspiration and callus extraction of eight rabbits were cultured (group I). The other eight rabbits were treated equally after four weeks of fracturization (group II). Simultaneously, the cultures were observed after one and two weeks. Four weeks later, they were harvested. Cells were counted using Neubauer hemocytometer. The average number of cells between the sources and groups were statistically analyzed using the unpaired t-test.

Results: In group I, there were 2.6 ± 0.1 x 104 cells in the culture of iliac crest bone marrow aspirate and 2.5 ± 0.1 x 104 cells in culture of callus extract from fracture site (p = 0.34). In group II, there were 2.7 ± 0.1 x 104 cells and 2.1 ± 0.1 x 104 cells, respectively (p < 0.001).

Conclusion: Fracture site callus at the second week post-fracturization may be potential as source of plastic-adherent cells compared with iliac crest bone marrow."

"ABSTRAKSaat ini terdapat perbaikan Angka Harapan Hidup (AHH) penduduk Indonesia dan penambahan populasi penduduk lanjut usia. Pada tahun 2017, AHH mencapai 71,06 tahun, dan jumlah lansia 23,4 juta orang (8,97% dari seluruh penduduk Indonesia). Hal ini berisiko meningkatkan kejadian penyakit degeneratif. Osteoartritis (OA) adalah penyakit yang sering dikaitkan dengan kondisi degeneratif dan mengakibatkan ketidakaktifan fisik. Pada Riskesdas 2013, penyakit Artritis berada di urutan kedua penyakit terbanyak diderita lansia dengan prevalensi 45% (55-64 tahun), 51,9% (65-74 tahun) dan 54,8% (usia >75 tahun). Pengobatan simtomatik dengan OAINS yang berkepanjangan dapat mengakibatkan efek samping yang fatal. Terdapat berbagai faktor risiko berkembangnya OA lutut, di antaranya konsentrasi serum Vitamin D (25(OH)D. Proporsi perempuan lansia dengan defisiensi 25(OH)D pada penelitian di Jakarta dan Bekasi mencapai 35,1%. Terdapat hubungan antara kadar Vitamin D (25(OH)D) yang rendah dengan nyeri lutut dan perubahan kartilago sendi lutut pada OA. Serum Cartilage Oligomeric Matrix Protein (COMP) merupakan produk degradasi penting dari kartilago sendi dan dapat menjadi marker diagnosis untuk OA lutut. Penelitian ini bertujuan mengetahui pengaruh pemberian suplemen Vitamin D (Alphacalcidol) selama 12 minggu terhadap derajat nyeri berdasarkan indikator WOMAC, dan kondisi obyektif kartilago sendi dengan perubahan marker serum COMP pada penderita OA lutut lansia. Disain penelitian uji klinis teracak, tersamar ganda, dan terkontrol plasebo. Subyek dengan OA lutut simtomatis direkruit secara consecutive sampling dan dilakukan anamnesis, diperiksa kondisi fisik, radiologi lutut, kadar serum Vitamin D (25(OH)D), serum Calcium dan marker COMP. Subyek dialokasikan secara acak (random allocation) pada kelompok perlakuan yang diberikan suplemen Vitamin D (Alphacalcidol) atau kelompok kontrol yang diberikan plasebo. Populasi sumber xviii Universitas Indonesia pada penelitian ini ialah pasien OA lutut lanjut usia yang berobat ke KPKM FKIK UIN Jakarta. Dari hasil pemeriksaan konsentrasi serum Vitamin D 25(OH)D sebelum dilakukan intervensi, 53,4% responden mengalami insufisiensi dan 12,3% responden mengalami defisiensi Vitamin D. Pemberian suplemen Vitamin D (Alphacalcidol) selama 12 minggu, mempengaruhi penurunan derajat nyeri berdasarkan indikator WOMAC pada penderita OA lutut lansia yang bermakna secara statistik dengan perbedaan perubahan skor pra dan pascaintervensi pada kelompok intervensi dibanding kontrol sebesar 2,174 (p=0,00). Pemberian suplemen Vitamin D (Alphacalcidol) selama 12 minggu, mempengaruhi penurunan konsentrasi serum COMP pada penderita OA lutut lansia, dengan perbedaan perubahan skor pra dan pascaintervensi pada kelompok intervensi dibandingkan kelompok kontrol sebesar 38,15 ng/ml namun tidak bermakna secara statistik (p=0,39)

ABSTRACTAt present there are improvements in the Life Expectancy (AHH) of the Indonesian population and the addition of the elderly population. In 2017, AHH reached 71.06 yo and the number of elderly people reached 23.4 million people (8.97% of the total population of Indonesia). This has the potential to increase degenerative diseases. Osteoarthritis (OA) is a disease that is often associated with degenerative conditions and physical inactivity. Riskesdas in 2013 stated that Arthritis was the second most common disease suffered by the elderly with a prevalence of 45% (55-64 yo), 51.9% (65-74 yo) and 54.8% (>75 yo). Symptomatic treatment with prolonged NSAIDs can cause fatal side effects. There are various risk factors for developing knee OA, including serum Vitamin D (25(OH)D) concentrations. The proportion of elderly women with 25(OH)D deficiency in studies in Jakarta and Bekasi reaches 35.1%. It has been found an association between low Vitamin D levels (25(OH)D) with knee pain in OA and changes in the knee joint cartilage. Cartilage Oligomeric Matrix Protein (COMP) is an important degradation product of joint cartilage and can be act as a diagnostic marker of knee OA. This study aims to determine the effect of Vitamin D supplementation (Alphacalcidol) for 12 weeks on the degree of pain based on WOMAC indicators, and the objective conditions of joint cartilage with changes in COMP serum markers in patients with knee OA in the elderly. The research design is a randomized, double-blind, and placebo-controlled clinical trials. Subjects with symptomatic knee OA will be recruited by consecutive sampling and continued with history taking, physical conditions examinatons, knee radiology, and blood test for serum vitamin D (25(OH)D), serum calcium and marker COMP. Subjects were then randomly allocated to the treatment group given Vitamin D supplements (Alphacalcidol) or the control group given a placebo. The source population in this study was elderly with knee OA patients xx Universitas Indonesia who went to Primary Health Care Clinic (KPKM) of FKIK UIN Jakarta. We found that before intervention was done, 53.4% of respondents had Vitamin D insufficiency and 12.3% of respondents had Vitamin D deficiency. The administration of Vitamin D supplements (Alphacalcidol) for 12 weeks, influenced the decrease in the degree of pain based on the WOMAC indicator in knee OA of elderly patients significantly, with differences in changes in pre and post intervention scores of 2.174 compare with control (p=0.00). The administration of Vitamin D supplements (Alphacalcidol) for 12 weeks, affected the decrease in the serum concentration of COMP in knee OA of elderly patients, with differences in changes in pre and post intervention scores in the intervention group compared to the control group of 38.15 ng/ml but not statistically significant (p=0.39)."
