This study set out to establish the clinical risk factors resulting in IPGF after OLT. METHODS: Eighty cases of OLT were analyzed. The IPGF group consisted of patients with alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) above 1500 IU/L within 72 hours after OLT, while those in the non-IPGF group had values below 1500 IU/L. Recipient-associated factors before OLT analyzed were age, sex, primary liver disease and Child-Pugh classification; factors analyzed within the peri-operative period were non-heart beating time (NHBT), cold ischemia time (CIT), rewarming ischemic time (RWIT), liver biopsy at the end of cold ischemia; and factors analyzed within 72 hours after OLT were ALT and/or AST values. A logistic regression model was applied to filter the possible factors resulting in IPGF. RESULTS: Donor NHBT, CIT and RWIT were significantly longer in the IPGF group than in the non-IPGF group; in the logistic regression model, NHBT was the risk factor leading to IPGF (P < 0.05), while CIT and RWIT were possible risk factors. In one case in the IPGF group, PGNF appeared with moderate hepatic steatosis. CONCLUSIONS: Longer NHBT is an important risk factor leading to IPGF, while serious steatosis in the donor liver, CIT and RWIT are potential risk factors.展开更多
文摘目的分析侵袭性牙周炎(aggressive periodontitis,AgP)患者牙周-正畸联合治疗长期疗效的相关影响因素。方法纳入2002年1月至2010年9月于北京大学口腔医学院·口腔医院牙周科就诊,并完成牙周-正畸治疗的AgP患者25例,收集初诊(T0)、正畸治疗完成后(T1)、正畸结束3年以上末次复查(T2)时的全口根尖X线片,通过根尖X线片评价患者根形态异常情况、正畸前后剩余牙槽骨高度(residual alveolar bone height,RBH)的变化。评价根形态异常对牙周-正畸治疗的影响,并进行多因素分析,评价与正畸后长期牙槽骨高度变化相关的牙和个体水平因素。结果T0、T1时统计25例患者的693颗牙,T2期随访14例患者,共观测368颗牙。牙周-正畸治疗前后,牙槽骨高度变化的主要影响因素为根形态异常(估计值为-2.392)、牙位(上颌牙vs.下颌牙估计值为3.139;前牙vs.后牙估计值为?3.469)和T0期的牙槽骨高度变化(估计值为-0.391)(P<0.05)。根形态异常、下颌牙、前牙以及T0时牙槽骨高度高,都是牙槽骨增加的不利因素。正畸后长期观察,牙槽骨高度变化的主要影响因素为牙位(上颌牙vs.下颌牙估计值为3.735;前牙vs.后牙估计值为-5.318)、T0时探诊深度(估计值为-1.594)和T0时牙槽骨高度(估计值为-0.498)(P<0.05)。下颌牙、前牙、T0时牙槽骨高度增加和T0探诊深度增加,都是正畸后长期牙槽骨增加的不利因素。结论多因素分析显示,正畸治疗结束时,牙槽骨高度变化的主要影响因素为根形态异常、牙位和T0时牙槽骨高度;正畸后3年以上复查,牙槽骨高度变化的主要影响因素为牙位、T0时的探诊深度和T0时牙槽骨高度。
