    ν•™μœ„λ…Όλ¬Έ(석사) -- μ„œμšΈλŒ€ν•™κ΅λŒ€ν•™μ› : μ˜κ³ΌλŒ€ν•™ μ˜ν•™κ³Ό, 2023. 2. μœ€μ •ν™˜.Background & Aims: There is no proven treatment for ursodeoxycholic acid (UDCA) refractory primary biliary cholangitis (PBC) other than obeticholic acid. Although fibrates have been reported to improve biochemical parameters, the long‐term effects remain unclear. This study evaluated the effect of fibrate on clinical outcomes of UDCA‐refractory PBC. Methods: Patients whose alkaline phosphatase (ALP) was not normalized with at least 13 mg/kg of UDCA treatment for >1 year were included from two tertiary referral centres. The primary outcome was ALP normalization. Secondary outcomes included the development of cirrhosis and hepatic deterioration. Immortal time bias was adjusted using the Mantel‐Byar method. Results: A total of 100 UDCA‐refractory PBC patients were included: 71 patients received UDCA alone (the UDCA group) and 29 patients received UDCA plus additional fibrate treatment of 160 mg/d fenofibrate or 400 mg/d bezafibrate (the fibrate/UDCA group). During the follow‐up period, the probability of ALP normalization was significantly higher in the fibrate/UDCA group (hazard ratio [HR] = 5.00, 95% confidence interval = 2.87-8.27, P < 0.001). Among 58 non cirrhotic patients (43 in the UDCA group and 15 in the fibrate/UDCA group), 19 patients (44.1%) in the UDCA group and none in the fibrate/UDCA group developed cirrhosis (HR = 0.12, P = 0.04). Hepatic deterioration (Child‐Pugh score increase or signs of decompensated cirrhosis) occurred in 17 patients (23.9%) of the UDCA group and none in the fibrate/UDCA group in which the difference was significant (HR = 0.12, P = 0.04). Conclusions: In patients with UDCA‐refractory PBC, additional fibrate treatment is associated with a higher probability of ALP normalization and a lower risk of cirrhosis development and hepatic deterioration.μ„œλ‘ : μ•„μ§κΉŒμ§€ 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚°μ— λΆˆμ‘ν•˜λŠ” μ›λ°œμ„± 담즙성 담관염에 λŒ€ν•œ μΉ˜λ£ŒλŠ” λͺ…ν™•νžˆ ν™•λ¦½λ˜μ§€ μ•Šμ€ 상황이닀. μ—¬λŸ¬ 후보 μ•½μ œλ“€ 쀑 νŒŒμ΄λΈŒλ ˆμ΄νŠΈλ“€μ˜ 경우 κ°„μˆ˜μΉ˜λ₯Ό ν¬ν•¨ν•œ 생화학적 μ§€ν‘œλ“€μ˜ ν˜Έμ „μ„ λ³΄μΈλ‹€λŠ” 보고듀은 일뢀 μžˆμ—ˆμœΌλ‚˜, μž₯κΈ°κ°„ νš¨κ³Όλ“€μ— λŒ€ν•΄μ„œλŠ” 아직 λͺ…ν™•νžˆ ν™•μΈλœ λ°”κ°€ μ—†λŠ” 상황이닀. 이에 λ³Έ μ—°κ΅¬μ—μ„œλŠ” 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚° λΆˆμ‘μ„± μ›λ°œμ„± 담즙성 λ‹΄κ΄€μ—Ό ν™˜μžλ“€μ—κ²Œ μžˆμ–΄ 파이브레이트 μΉ˜λ£Œμ™€ μž„μƒμ  μ§€ν‘œλ“€ κ°„μ˜ 관계λ₯Ό ν™•μΈν•˜κ³ μž ν•˜μ˜€λ‹€. 방법: 두 개의 3μ°¨ λ³‘μ›μ—μ„œ μ›λ°œμ„± 담즙성 λ‹΄κ΄€μ—ΌμœΌλ‘œ 진단받고 치료 λ°›λŠ” ν™˜μžλ“€ 쀑 μΆ©λΆ„ν•œ μš©λŸ‰(13mg/kg의 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚°)을 1λ…„ λ„˜κ²Œ μ‚¬μš©ν•˜μ˜€μŒμ—λ„ ν˜ˆμ€‘ μ•ŒμΉ΄λ¦¬μ„± μΈμ‚°ν™”λΆ„ν•΄νš¨μ†Œκ°€ 정상화 λ˜μ§€ μ•Šμ€ ν™˜μžλ“€μ„ λŒ€μƒμœΌλ‘œ 연ꡬ가 μ§„ν–‰λ˜μ—ˆλ‹€. 일차 평가 λ³€μˆ˜λ‘œλŠ” μ•ŒμΉ΄λ¦¬μ„± μΈμ‚°ν™”λΆ„ν•΄νš¨μ†Œμ˜ 정상화 μ—¬λΆ€μ˜€μœΌλ©°, 이차 평가 λ³€μˆ˜λ‘œλŠ” κ°„κ²½ν™” 및 κ°„λΆ€μ „ λ°œμƒ μ—¬λΆ€μ˜€λ‹€. μ‘°κΈ°λ°œκ²¬κΈ°κ°„ 였λ₯˜μ˜ 문제λ₯Ό ν•΄κ²°ν•˜κΈ° μœ„ν•΄μ„œ Mantel-Byar 방법을 ν™œμš”ν•˜μ˜€λ‹€. κ²°κ³Ό: 총 100λͺ…μ˜ 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚° λΆˆμ‘μ„± μ›λ°œμ„± 담즙성 λ‹΄κ΄€μ—Ό ν™˜μžλ“€μ΄ 연ꡬ에 ν¬ν•¨λ˜μ—ˆλ‹€: 71λͺ…μ˜ ν™˜μžλ“€μ€ 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚°λ§Œ 처방 λ°›μ•˜μœΌλ©°(UDCA κ΅°), 29λͺ…μ˜ ν™˜μžλ“€μ€ 파이브레이트λ₯Ό λ™μ‹œ 처방 λ°›μ•˜λ‹€(fibrate/UDCA κ΅°). κ΄€μ°° κΈ°κ°„ 쀑, fibrate/UDCA κ΅°μ—μ„œ μ•ŒμΉ΄λ¦¬μ„± μΈμ‚°ν™”λΆ„ν•΄νš¨μ†Œ 수치의 μ •μƒν™”μ˜ κ°€λŠ₯성이 UDCAꡰ에 λΉ„ν•΄μ„œ μœ μ˜ν•˜κ²Œ λ†’μ•˜λ‹€(μœ„ν—˜λ„ [HR]=5.00, 95% 신뒰ꡬ간 = 2.87-8.27, P<0.001). 간경변이 μ—†λŠ” 58λͺ…μ˜ ν™˜μž(UDCA κ΅° 43λͺ…, fibrate/UDCA κ΅° 15λͺ…)λ“€μ—μ„œ 19λͺ…(44.1%)의 ν™˜μžλ“€μ—μ„œ 간경변이 λ°œμƒν•˜μ˜€λŠ”λ°, μ΄λŠ” λͺ¨λ‘ UDCA κ΅°μ—μ„œλ§Œ λ°œμƒν•˜μ˜€λ‹€(HR=0.12, P=0.04). κ°„λΆ€μ „(2점 μ΄μƒμ˜ μ°¨μΌλ“œ-퓨 점수 증가, λ˜λŠ” λΉ„λŒ€μƒμ„± κ°„κ²½λ³€μ˜ λ°œμƒ) λ˜ν•œ 17λͺ…(23.9%) μ—μ„œ λ°œμƒν•˜μ˜€λŠ”λ°, λͺ¨λ‘ UDCA κ΅°μ—μ„œλ§Œ λ°œμƒν•˜μ˜€λ‹€(HR=0.12, P=0.04). κ²°λ‘ : 우λ₯΄μ†Œλ°μ˜₯μ‹œμ½œλ¦°μ‚° λΆˆμ‘μ„± μ›λ°œμ„± 담즙성 λ‹΄κ΄€μ—Ό ν™˜μžλ“€μ—κ²Œ μžˆμ–΄ 좔가적인 파이브레이트 치료λ₯Ό ν•˜λŠ” 경우, μ•ŒμΉ΄λ¦¬μ„± μΈμ‚°ν™”λΆ„ν•΄νš¨μ†Œμ˜ μ •μƒν™”μ˜ ν™•λ₯ μ΄ λ†’μ•„μ§€λŠ” 것과 κ°„λΆ€μ „ λ˜λŠ” κ°„κ²½ν™” λ°œμƒ κ°μ†Œμ™€ 연관성이 μžˆμ–΄λ³΄μΈλ‹€.Introduction 1 Methods 3 Patients 3 Treatment 4 Outcomes and evaluation 4 Statistical analysis 5 Results 8 Baseline characteristics 8 Biochemical normalization 11 Long-term liver-related events 19 Safety 36 Discussion 38 References 43 Abstract 50석

[영문] Bone morphogenetic proteins(BMPs) are regarded as members of the transforming growth factor-Ξ² superfamily with characteristic features in their amino acid sequences. A number of studies have demonstrated the biologic activities of BMPs, which include the induction of cartilage and bone formation. Recently there was a attempt to overcome a limitation of mass production, and economical efficieny of rh-BMPs. The method producing PTD by using bacteria have advantages of acquiry a mass of proteins. Hences, a new treatment which deliver protein employed by protein transduction domain(PTD) has been tried. The purpose of this study was to evaluate the bone regenerative effect of TATBMP-2 and TAT-HA2-BMP-2 employed by PTD from HIV-1 TAT protein for protein translocation in the rat calvarial model. An 8mm calvarial, critical size osteotomy defect was created in each of 32 male Spraque-Dawley rats(weight 250~300g). The animals were divided into 4 groups of 32 animals each (4 animals/group/healing interval). The defect was treated with TATBMP-2/ACS(Absorbable collagen sponge) (TATBMP-2 0.1 mg/ml) , TAT-HA2-BMP-2/ACS(TAT-HA2-BMP-2 0.1mg/ml) , ACS alone or left untreated for surgical control(negative control). The rats were sacrificed at 2 or 8 weeks postsurgery, and the results were evaluated histologically. The results were as follows: 1.New bone formation were not significantly greater in the TATBMP-2/ACS group relative to negative, and positive control groups. 2.New bone was evident at the defect sites in TAT-HA2-BMP-2/ACS group relative to negative, positive control and TATBMP-2 groups. There were a little bone regeneration in TATBMP-2 groups. While, enhanced local bone formation were observed in TAT-HA2-BMP-2 group. But, The results was not the same in all rat defects. Therefore, further investigations are required to develop a method, which disperse homogenously, and adhere to target cells.ope
