Background
The main challenge with cytomegalovirus (CMV) prophylaxis in IgG donor-positive/recipient-negative (D+/R–) kidney transplant recipients is late-onset CMV disease. We evaluated a novel protocol for the prevention of late-onset CMV infection and disease in D+/R? organ recipients.Methods
Our prospective, observational, cohort study included 100 adult kidney transplant recipients. Prophylaxis with low-dose valganciclovir (450 mg/d, 3 times a week for 6 months) was administered to D+/R? recipients. Risk factors for CMV infection and disease were identified. Renal function and the outcomes of CMV infection and disease were compared between D+/R? (n = 15) and recipient-positive (R+; n = 81) organ recipients.Results
D+/R? recipients showed significant independent risk factors with high hazard ratios for CMV infection (2.04) and disease (10.3). The proportion of CMV infection in D+/R? and R+ recipients was 80% and 46% (P = .023), and that of CMV disease was 33% and 6.2% (P = .008), repectively. D+/R? recipients developed CMV infection and disease within 6 months after transplantation. However, both CMV infection- and disease-free survival rates beyond 1 year post-transplantation defined as late-onset were stable in D+/R? recipients. Moreover, serum creatinine levels at 1 year post-transplantation were comparable between D+/R? and R+ recipients (1.45 ± 0.71 vs 1.16 ± 0.35 mg/dL, P = .26).Conclusion
Our novel protocol prevented late-onset CMV infection and disease beyond 1 year post-transplantation in D+/R? recipients. 相似文献2.

Background
Cytomegalovirus (CMV) infection can increase morbidity and mortality in kidney transplant (KT) patients. Chemoprophylaxis with valganciclovir (VGCV) is recommended for ABO-incompatible (ABOi) KT patients as it significantly reduces CMV disease and infection. The recommended dose of VGCV for prevention of CMV in a KT recipient is 900 mg once daily, and the treatment duration is 6 months. However, because it is expensive, sufficient amounts might not be administered.Methods
We investigated whether ultralow-dose VGCV (450 mg every other day) and short dosing period (3 months) was sufficient to prevent CMV infection after ABOi KT. We retrospectively evaluated 74 adult CMV-seropositive donor/CMV-seropositive recipient (D+/R+) ABOi KT recipients from June 2009 to July 2016 who received ultralow-dose VGCV prophylaxis for 3 months. The primary outcome was occurrence of CMV infection. Secondary outcomes were leukopenia and thrombocytopenia.Result
All patients received intravenous rituximab 200 mg once and plasmapheresis for reduction of anti-A/B antibodies and interleukin-2 antibodies before undergoing ABOi KT. Mean prophylaxis and follow-up durations were 3 and 52 months, respectively. One patient died of bacterial pneumonia. Four patients lost graft function and were undergoing hemodialysis; 3 cases were caused by antibody-mediated rejection, and 1 was due to mechanical complication after surgery. Fortunately, CMV infection did not occur in any patient.Conclusion
Ultralow-dose VGCV is an effective prophylaxis for D+/R+ ABOi KT recipients. Especially, ultralow-dose VGCV CMV infection prevention protocol in Asian populations reduced the side effects and cost. 相似文献3.

Background
Cytomegalovirus-negative recipients of kidneys from cytomegalovirus (CMV)-positive donors (D+/R?) are at high risk to develop severe clinical manifestations of CMV disease. Long-term data about incidence and timing of CMV seroconversion, CMV disease, and the influence of prolonged valganciclovir prophylaxis on the clinical course of CMV infection are missing.Methods
We conducted a retrospective long-term study of 89 consecutive CMV D+/R? kidney transplant recipients transplanted between 2003 and 2012. All recipients received valganciclovir prophylaxis after transplantation (median 187 [126-261] days) with a median dose of 213 (181-338) mg/d. Long-term outcome was assessed over a maximum of 10 years post-transplant.Results
During follow-up (median 62 months) 60 of 89 (67%) patients had CMV seroconversion, and 29 of 89 (33%) developed symptomatic CMV disease. In addition, in 38 of the 60 (63%), seroconversion occurred during prophylaxis (median 154 days post-transplant), and in 22 patients, after the end of prophylaxis (median 320 days after transplantation). Baseline characteristics of the 2 groups did not differ significantly. Seroconversion during prophylaxis vs seroconversion after the end of prophylaxis was associated with significantly lower incidence of CMV disease (34% vs 73%, P = .007), less severe CMV disease (16% vs 64%, P < .001), and fewer organ manifestations (26% vs 64%, P = .006). The risk of CMV disease was limited to the first 475 days after transplantation. Valganciclovir resistance occurred in just 1 case (1%).Conclusions
Prolonged prophylaxis with low-dose valganciclovir allowed CMV seroconversion during prophylaxis in a high proportion of D+/R? patients. Seroconversion occurred after a median of 154 days and was associated with significantly lower incidence of CMV disease, less severe CMV disease, and fewer CMV complications. 相似文献4.

Background
Resistant cytomegalovirus (R-CMV) is an emerging problem in the renal transplantation population. The most frequent CMVs are high-resistance mutations (UL97 gene).Methods
We describe our experience in management of R-CMV after renal transplant at our center (2012–2016).Results
We encountered 3 cases of R-CMV infection after renal transplant (all primary infections). All 3 patients received induction therapy with corticosteroids, tacrolimus, and mycophenolate mofetil. The first patient (basiliximab induction, preemptive CMV) developed CMV replication on day +53, which responded poorly both to standard-dose valganciclovir (vGCV) and high-dose ganciclovir (GCV) (creatinine clearance [CrCl] >70 mL/min; vGCV 900 mg twice daily for 50 days and GCV 7.5 mg/kg twice daily for 8 days). Hematologic toxicity occurred. The R-CMV test was positive and foscarnet (FOS) was initiated (90 mg/kg twice daily for 21 days). The second patient presented CMV infection (day +30, thymoglobulin induction, CMV prophylaxis), which was not controlled with the high dose (CrCl 23 mL/min; GCV 3.5 mg/kg twice daily and vGCV 900 mg twice daily), resulting in severe neutropenia. R-CMV was detected and FOS initiated (FOS 50 mg/kg twice daily for 7 days and 50 mg/kg every 2 days for 13 days). The third patient's infection occurred on day +22 (basiliximab induction, preemptive CMV). Standard-dose vGCV was uneffective (CrCl >70 mL/min, vGCV 900 mg twice daily) and it did not respond to the high dose (GCV 7.5 mg/kg twice daily and vGCV 2700 mg/d). Moderate hematologic toxicity occurred. R-CMV was diagnosed and FOS treatment begun (FOS 70 mg/kg per day for 2 weeks).Conclusions
Resistant CMV infection may be severe due to viral infection and side effects of high-dose antiviral treatment. We presented 3 cases requiring the use of FOS in the absence of response or toxic effects from the usual treatment, with an optimal sustained response (temporary in case 2) and without serious side effects. 相似文献5.

Background
Cytomegalovirus (CMV) is the most common viral infection after kidney transplantation and is associated with significant morbidity and mortality. Recent studies showed that CMV-specific CD8+ T cells play the crucial role in protection against CMV. The Quantiferon-CMV (QF-CMV) is an interferon gamma (IFN-γ) release assay (IGRA test) that measures the IFN-γ response to a range of T-cell epitopes of CMV. In the present study, we analyzed the clinical utility of QF-CMV assay to predict CMV infection in kidney transplant recipients and evaluated if reactive result in QF-CMV test could be predictor of the duration of treatment.Methods
We studied 75 renal transplant recipients who had IGRA testing just before transplantation. The donor and recipient variables were reported from the clinical history. The variables related to transplantation were collected from transplantation process data and included CMV infection or disease, CMV treatment, and immunosuppressive treatment. Laboratory variables were C3-C4 complement fractions and DNA quantification of CMV.Results
Fifty percent of patients had CMV infection, and 35.9% had CMV disease. The time of negativization of CMV DNA was 56.61 ± 23.5 days. Univariate analysis related to CMV infection only showed a statistically significant relation with thymoglobulin treatment (P = .001). Statistically significant variables in relation with CMV infection incidence were donor serology (P = .044) and thymoglobulin treatment (P = .004). The probability of CMV infection was lower with positive IGRA assay (P = .025).Conclusion
We found that IFN-γ response measured by QF-MV is a protective factor against CMV infection in post-transplantation kidney recipients. 相似文献6.

Introduction
Cytomegalovirus (CMV) infection is a relevant cause of morbidity and mortality in transplantation patients. Its major incidence is in the first year and viral replication is related to acute rejection, survival reduction, and graft vascular disease.Objective
This study aims to evaluate retrospectively whether a high dose of calcineurin inhibitors correlates with CMV-positive polymerase chain reaction (PCR), need for treatment, and death in cardiac transplantation patients.Methods
This is a case-control study including patients who underwent transplantation between 2014 and 2016. They were separated into two groups (positive or negative PCR) and evaluated for dosage serum levels of cyclosporine and tacrolimus. Patients were classified with adequate dose of immunosuppressant or high dose, and was analyzed that there was any association with those and positive CMV-PCR, need for treatment for CMV, and deaths. For statistical analysis, the Student t test was used for the quantitative variables and the Fisher’s Exact Test for qualitative variables. To show CMV-free survival, the Kaplan-Meier curve was used. The level of significance was set at 5%.Results
CMV-positive PCR in the sample was 72% for a total of 50 individuals. Positive PCR correlated with a high dose of calcineurin inhibitors in a statistically significant way (P = .002), as did a high dose of cyclosporine (P = .004); however, a high dose of tacrolimus had no such association (P = .17). When a high dose was assessed with a need for treatment, the chance of needing treatment increased more than eight times (P = .024; odds ratio = 8.25; 95% CI = 1.33 to 51.26), which was different from results found with high-dose tacrolimus (P = 1.0). However, no significant association was found in relation to deaths.Conclusions
Tacrolimus serum levels showed no association with CMV-PCR, which was different from serum cyclosporine, which showed association with CMV-PCR positivity, increasing the need for treatment approximately 8-fold, without association with death. 相似文献7.

Background
Topical antibiotics have been shown to reduce exit-site infection and peritonitis. The aim of this study was to compare infection rates between mupirocin and gentamicin.Methods
Multiple comprehensive databases were searched systematically to include relevant randomized controlled trials and observational studies. Pooled risk ratios (RRs) and 95% confidence intervals were calculated for the incidences of exit-site infection and peritonitis.Results
Seven studies (mupirocin group n = 458, gentamicin group n = 448) were analyzed for exit-site infection. The risk of gram-positive exit-site infection was similar between the groups. Gram-negative exit-site infection rate was higher in the mupirocin group (RR = 2.125, P = 0.037). Six studies were assessed the peritonitis risk. There was no difference in the gram-positive and -negative peritonitis rate.Conclusions
Topical use of gentamicin is associated with fewer exit-site infections caused by gram-negative organisms. Gentamicin has comparable efficacy to mupirocin for peritonitis and gram-positive exit-site infection. 相似文献8.

Background
Although the clinical outcomes of pediatric renal transplantation (RT) in developed countries have improved significantly, the data on clinical outcomes in developing countries are wildly different.Methods
Children and adolescents who had undergone RT at Ramathibodi Hospital between March 2001 and August 2014 were included.Results
Patients were divided into 2 groups: living related donor (LRD) group (n = 13) and deceased donor (DD) group (n = 30). Prolonged cold ischemic time over 13 hours was significantly associated with delayed graft function (P = .029). The prevalence of infection was 90.7%, in which urinary tract infection (UTI) was the most common infection. Although almost none of the patients in the LRD group received induction therapy, the prevalence of rejection was not significantly different between the 2 groups (P = .817). The comparison of graft survivals between LRD and DD groups were 100% vs 100%, 92.3% vs 100%, and 85.7% vs 81.8% at 1, 3, and 5 years, respectively (P = .938). Recurrent UTI and cytomegalovirus (CMV) infection had a negative effect on graft function at 1-year follow-up (P < .05). Rejections, bladder dysfunction, and donors aged ≥50 years were associated with graft deterioration at 3 years after RT (P < .01). None of these patients died with functioning graft.Conclusion
This study demonstrated good graft and patient survival in Thai pediatric RT recipients. Although recurrent UTI and CMV infection were related to graft dysfunction at 1-year follow-up, infections had no effect on graft and patient survival in long-term follow-up. 相似文献9.

Purpose
To clarify whether there is any difference in mid-term clinical and radiologic outcomes between bone-grafted laminoplasty (BG LAMP) and non-bone-grafted laminoplasty (non-BG LAMP) when used to treat cervical spondylotic myelopathy.Background
Conventional BG LAMP includes bone grafting at the lamina hinge site to prevent closure of the lamina postoperatively, but it often results in segmental fusion and sometimes causes loss of cervical mobility and lordotic alignment. Non-BG LAMP can now be performed to address this problem and preserve mobility postoperatively. However, there have been no studies comparing BG LAMP and non-BG LAMP to date.Methods
Forty-one patients who underwent BG LAMP (n = 24) or non-BG LAMP (n = 17) and had 5 years of follow-up were enrolled in the study. Neurological status was assessed preoperatively and postoperatively using the Japanese Orthopedic Association (JOA) scoring system. The Numeric Rating Scale (NRS) was used to assess neck pain after surgery at the final visit. Radiographic parameters were evaluated at 1, 3, and 5 years after surgery. Postoperative segmental fusion was defined as the level at which the segmental flexion–extension range of motion was <1°.Results
There was no significant difference in JOA score or recovery rate between the groups. NRS score was significantly lower in the BG group, indicating less neck pain (P < .01). The lordotic angle and range of motion at C2-C7 were significantly decreased in the BG group (P < .05). The segmental fusion was evident from 1 year postoperatively in both groups, but the fusion rate was significantly higher in the BG group (P < .05).Conclusions
Neurologic outcomes were similar between the two groups, whereas axial symptom was lower in the BG group than in the non-BG group.Level of evidence

Background
Adverse events due to conventional immunosuppressive therapy decrease both graft and patient survival. We aimed to establish a new protocol using everolimus (EVR) to safely minimize conventional immunosuppressants in maintenance kidney transplant recipients.Methods
A total of 86 consecutive kidney transplant recipients with no complications were maintained with triple-drug combination therapy (conventional group). In case of complications, the administration of very low-dose tacrolimus (C0: 5.0 to <3.0 ng/mL), reduced mycophenolate mofetil (1000–1500 to 500–1000 mg), and EVR (C0: 3.0–5.0 ng/mL) and methylprednisolone withdrawal (2–4 to 0 mg) were simultaneously conducted (EVR group). Graft survival and acute rejection rate were compared between groups. Within the EVR group, the dose of conventional immunosuppressants was compared between pre- and post-EVR administration. Renal function was evaluated 1 year post-EVR administration.Results
All grafts survived in the conventional (n = 50) and EVR (n = 36) groups, and biopsy-proven acute rejection rate exhibited no significant difference between these groups (12% vs 17%; P = .55). Furthermore, no acute rejection occurred post-EVR administration. In the EVR group, all immunosuppressants significantly decreased post-EVR administration compared with those pre-EVR administration (P < .01), and serum creatinine significantly improved at postoperative year 1 (P = .031).Conclusions
EVR administration enables very low-dose tacrolimus administration, helps reduce mycophenolate mofetil and steroid withdrawal, and ameliorates renal function in maintenance kidney transplant recipients experiencing complications associated with conventional immunosuppressive therapy. 相似文献11.

Aim
We designed a retrospective case-control study to determine the efficacy and feasibility of everolimus (EVR) combined with low-dose tacrolimus (Tac) ab initio versus standard-dose Tac after liver transplantation (LT).Methods
Seventy-one adult LT patients, receiving EVR and low-dose Tac without corticosteroids or induction therapy from postoperative day 1 (EVR group) were compared with a well-matched control group of 61 recipients treated with standard-dose Tac in association with antimetabolite.Results
Baseline characteristics for the two groups were comparable. The overall patient and graft survival rates were similar (P = .908). Liver function was stable during the follow-up. In the EVR group, biopsy-proven acute rejection occurred in two cases (2.8%), whereas chronic rejection occurred in one (1.4%). The EVR group experienced a better renal function already after 2 weeks (estimated glomerular filtration rate: 89.85 [36.46 to 115.3] mL/min/1.73 m2 vs. 68.77 [16.11 to 115.42] mL/min/1.73 m2; P = .013), which was also observed after a median time of 27 months (range, 0 to 82 months) from LT (estimated glomerular filtration rate: 80 [45 to 118.3] mL/min/1.73 m2 vs. 70.9 [45 to 88.4] mL/min/1.73 m2; P = .04). After a median time of 27 months, the EVR group showed lower incidence of arterial hypertension and insulin-dependent diabetes mellitus.Conclusion
Ab initio EVR-based immunosuppression could be a valid option immediately after surgery in recipients at high-risk for post-LT renal impairment. 相似文献12.

Background
Perioperative insulin resistance is associated with significant hyperglycemia-related morbidity in patients undergoing major surgery. We sought to assess the effect of preoperative loading with a low-dose maltodextrin/citrulline solution compared to a commercially available sports drink on glycemic levels in an established colorectal enhanced recovery program.Methods
Retrospective analysis was undertaken of elective non-diabetic colectomies and enterectomies from January 2016–March 2017. Cohorts included simple (SIM) and complex carbohydrate (COM) groups. Statistical analysis was performed with linear and logarithmic regression.Results
83 patients were included (42 SIM, 41 COM). SIM group was older (61.7 vs 52.7 p = 0.012) Glycemic variability was less in the COM group (7.6% vs 21.4% P = 0.034). The frequency of hyperglycemia, postoperative complications, and length of stay trended higher in the SIM group.Conclusions
This retrospective analysis identifies significant improvement in the perioperative glycemic variability with preoperative low dose complex carbohydrate loading compared to simple carbohydrate loading in colorectal surgery patients. 相似文献13.

Background
The effectiveness of everolimus (EVR) for ABO-incompatible (ABOi) kidney transplantation is unknown. We evaluated outcomes of conversion from steroid to EVR in ABOi kidney transplant recipients.Methods
We performed a retrospective observational cohort study of 33 de novo consecutive adult ABOi living donor kidney transplant recipients. Desensitization was performed using 0 to 4 sessions of plasmapheresis and 1 to 2 doses of 100 mg rituximab according to the anti-A/B antibody titer. ABOi recipients were administered a combination of tacrolimus, mycophenolate mofetil, and methylprednisolone. Diabetic patients were converted from methylprednisolone to EVR at 1 to 15 months post-transplantation to prevent diabetes progression. Graft outcomes, hemoglobin A1c (HbA1c) levels, and cytomegalovirus infection rates were compared between the EVR (n = 11) and steroid (n = 22) groups.Results
Mean postoperative duration was 814 and 727 days in the EVR and steroid groups, respectively (P = .65). Between the 2 groups, graft survival rate (100% vs 95.5%, P > .99), acute rejection rate (9.1% vs 18.2%, P = .64), and serum creatinine levels (1.46 mg/dL vs 1.68 mg/dL, P = .66) were comparable. Although HbA1c levels were elevated in the steroid group (5.47%, 5.87%; P = .003), no significant deterioration was observed in the EVR group without additional insulin administration (6.10%, 6.47%; P = .21). Cytomegalovirus infection rate was significantly lower in the EVR group than in the steroid group (18.2% vs 63.6%, P = .026).Conclusion
Conversion from steroid to EVR in ABOi kidney transplant recipients maintained excellent graft outcomes and avoided diabetes progression and cytomegalovirus infection. 相似文献14.

Background
The significance of proinflammatory M1 (classically activated) and profibrotic M2 (alternatively activated) macrophages in antibody-mediated rejection (ABMR) after kidney transplantation has not been investigated.Methods
Fifty-five biopsy-confirmed ABMR samples were stained with MRP 8/14 (a marker of M1 macrophages) and CD163 (a marker of M2 macrophages), and positive cells were counted in glomeruli and the tubulointerstitium, respectively. Patients were classified into M1 and M2 polarization groups according to the glomerular and tubulointerstitial M1:M2 ratio, and the results were compared with Banff scores, serum creatinine level, estimated glomerular filtration rate (eGFR), and graft survival.Results
The glomerular M2 polarization group showed significantly higher chronic glomerulopathy scores, serum creatinine levels, and lower eGFR at the time of biopsy (P = .019 and P = .015, respectively) and 3-month postbiopsy (P = .016 and P = .032, respectively) than the M1 polarization group. The tubulointerstitial M2 polarization group had significantly lower glomerulitis, arteritis, peritubular capillaritis, and glomerulitis + peritubular capillaritis scores than the M1 polarization group, but there was no significant difference in renal function. Long-term graft survival was not associated with macrophage polarization.Conclusion
Glomerular M2 polarization in ABMR biopsy samples is associated with chronic glomerular injury and poorer graft function, but without graft survival. 相似文献15.

Background
End-stage renal disease due to type 1 diabetes mellitus appears to be a regular indication for simultaneous pancreas and kidney transplantation (SPKT). Although transplantation improves a patient's health condition, it does not mean that all complications will be eliminated.Methods
We performed a retrospective analysis of 73 patients who underwent SPKT and follow-up between 1988 and 2015 at our institute. The number, duration, and reasons for hospitalization at 1, 5, 10, and 15 years after SPKT were analyzed.Results
The average number of hospitalizations at 1, 5, 10, 15 years after SPKT were 1.66, 0.39, 0.36, and 0.33, respectively. The main reason for hospitalization over the 15-year period was infections, at 32.4% (SD, 6.8%). Within the first year after SPKT, 6.8% of hospital admissions were caused by cytomegalovirus (CMV) infection. Over time, the percentage of hospitalizations for cardiovascular complications increased from 0.6% at 1 year to 29% at 12–15 years. Incidence of hospitalization due to cardiovascular complications correlated with a longer period of dialysis and a diagnosis of ischemic heart disease before transplant (r = 0.56, P = .004; r = 0.54, P < .0001, respectively). At 12–15 years after transplantation, 18.2% of hospitalizations were caused by secondary complications of diabetes.Conclusion
The most common reason for hospitalization after SPKT is infectious complications. In the first year posttransplant, there is a high percentage of CMV infections. Hospitalization associated with cardiovascular complications was found to be most common in the latter follow-up period and showed a correlation with longer dialysis period. 相似文献16.

Background
Hepatic artery thrombosis (HAT) is reported in 4%-15% of orthotopic liver transplants. Risk factors include technical error in the anastomosis, vascular anatomic variation, and high microvascular resistance. The aim of this study was to verify the incidence of HAT, early or late, and possible risk factors.Methods
This was a retrospective study from January 2007 to December 2012 at the State University of Campinas. Variables analyzed were age, sex, cold and warm ischemia times, underlying disease, presence of hepatocellular carcinoma, Model for End-Stage Liver Disease (MELD) score, arterial anatomic variation in the graft, cytomegalovirus (CMV) infection, rejection, biliary complications, retransplantation rate, and survival.Results
The incidence of HAT was 21/263, or 7.9%. Pure average MELD score was 22 ± 7.4. There was vascular anatomic variation in the graft in 14.2% of cases, in the majority (66.6%) a right hepatic artery from the superior mesenteric artery, and 4.76% of patients had CMV infection and acute cellular rejection (1 case each). There were biliary complications in 38% of patients, 13.3% of cases in patients with early HAT, and 100% of patients with late HAT (P = .002). Body mass index in late HAT was higher (P = .01).Conclusions
Late HAT was related to a significant increase in biliary complications (stenosis), and the survival rate was similar at 5 years. 相似文献17.

Introduction
Sarcopenia and osteopenia are highly prevalent in older patients, and are associated with a high risk for falls, fractures, and further functional decline. However, related factors in kidney transplant recipients suffering from osteosarcopenia, the combination of sarcopenia and osteopenia, remain unknown.Material and methods
Fifty-eight transplant recipients (42 men and 16 women), with a mean age of 46.6 ± 12.7 years, were enrolled in this study. Sarcopenia was diagnosed according to the criteria of the Asia Working Group for Sarcopenia. Osteopenia was diagnosed according to World Health Organization criteria using bone mineral density (BMD) of the lumbar spine. Patients who met the diagnostic criteria of both diseases were defined as having osteosarcopenia.Results
Ten patients had osteosarcopenia. According to univariate analyses, there were significant differences between osteosarcopenia group and non osteosarcopenia group in age (P = .002), duration of dialysis (P = .013), vitamin D levels (P = .002), and MET (P = .007). There was a significant positive correlation between vitamin D level and MET (r = .464; P < .001). The results of the multivariate analysis indicated that only MET was a relevant factor in osteosarcopenia.Conclusion
Duration of dialysis, low vitamin D levels, and physical activity after kidney transplantation were related to osteosarcopenia. These results suggested that osteosarcopenia in kidney transplant recipients is a carryover from the dialysis period. 相似文献18.

Donor safety is one of the most important factors in living-donor liver transplantation. Duodenal ulcer (DU) is a common postoperative complication. Here we aimed to reveal the risk factors associated with postoperative DU in the donors.Methods
Between April 2007 and March 2017, 318 cases underwent donor hepatectomy for liver transplantation at Kumamoto University Hospital. We classified the donors into two groups: a DU group and a non-DU group. DU was defined as mucosal break with unequivocal depth requiring an endoscopic procedure. The characteristics and clinical factors of the donors were retrospectively analyzed.Results
Postoperative DU occurred in 17 donors during the study period. The mean interval after donor hepatectomy to occurrence of DU was 124.8 ± 185.4 days. The two groups were comparable in terms of age at time of the donor hepatectomy (P = .45). The male-to-female ratio (P = .03) was significantly different between the two groups and left-side hepatectomy was performed more often in the DU group (P = .003). Multivariable logistic regression revealed that left-side hepatectomy was independently associated with postoperative DU in the donors.Conclusions
These findings indicated that left-side hepatectomy is a risk factor for postoperative DU in the donors. 相似文献19.

Intoduction
Infection by cytomegalovirus (CMV) is a major cause of morbidity among immunosuppressed patients, especially after solid organ transplantation. The risk of CMV after organ transplantation is strongly related to the serology of the donor and the recipient. The objective of this study was to analyze the outcomes and costs of pre-emptive therapy in patients after liver transplantation with donor-positive/recipient-negative (D+/R?) serostatus.Methods
This retrospective study analyzed all patients who underwent liver transplantation with CMV serostatus D+/R? between January 2012 and December 2015. The service protocol adopts pre-emptive therapy. The outcomes and costs of this therapy are described.Results
Of the 119 patients undergoing liver transplantation, 19 were D+/R? and entered the main analysis. Of these, 7 had positive polymerase chain reaction (PCR) results, and 1 developed CMV disease. Of the 6 patients who received no treatment, none developed CMV disease. Analyzing costs, pre-emptive therapy for these patients generated service savings of R$32,346.00.Conclusions
Although outcomes of universal prophylaxis and pre-emptive therapy are similar, pre-emptive therapy save on costs and have to be considered in patients with high-risk CMV disease after liver transplantation. 相似文献20.
