ObjectiveTo examine the characteristics of Rhodococcus equi (R. equi) infection for better awareness of this disease.MethodsThe clinical data of a patient with pulmonary abscess caused by R. equi after renal transplantation were reported. We also reviewed the reports of infections caused by R. equi.ResultsThe clinical manifestations and laboratory examination of the patient were consistent with the characteristics of R. equi infection. The growth of R. equi was found in sputum and blood culture. The follow-up data showed that the treatment was effective. Literature search identified 23 similar patients. In all the 24 patients (containing this one), the time of infection after renal transplantation ranged from 4 months to 11 years. There were 21 patients with cumulative pulmonary infection, and 10 patients had a clear epidemiological history of direct or indirect contact with horses. Eighteen patients improved after regular antibacterial treatment or surgical treatment.ConclusionsOpportunistic infections caused by R. equi mainly affect transplant recipients and other patients with lower immunity. Infections caused by R. equi may affect many organ systems with various manifestations. The optimal therapy is not established due to the rarity of this infection. Clinicians should select antibiotic agents rationally based on antimicrobial susceptibility testing and treatment response of patients.
ObjectivesTo establish statistical analysis and result reporting model for evaluation of the applicability of the clinical guidelines. We conducted empirical study for clinical guidelines for diagnosis and treatment of renal transplantation rejection in China.MethodsA cross-sectional survey was conducted to select 16 medical institutions in China which had carried out kidney transplantations. In each medical institution, 6 to 8 clinicians from the kidney transplantation department or related departments were selected to complete the questionnaire. Descriptive analysis was carried out for characteristics of evaluators, scores of each dimension, access to guidelines and factors affecting implementation. The Kruskal-Wallis rank sum test and Nemenyi test were used for multi-group comparison and pairwise comparison. Multiple linear regression with stepwise strategy were used to screen out the association factors.ResultsIn this survey, 128 questionnaires were distributed, in which 105 valid questionnaires were collected, and the recovery rate was 82.03%. The subjects of this survey were all kidney transplant clinicians from public tertiary hospitals, with an average 10.95 years of working time. The results showed the accessibility score was lowest and the acceptability score was highest. The results of multi-group comparison and multiple linear regression analysis showed that familiarity with the guidelines was the influencing factor of each score (P<0.05). The guidelines were primarily obtained from biomedical literature database (73.3%), academic journals (55.2%) and academic conferences (55.2%). Among the evaluators, 44 (41.9%) believed that there were implementation obstacles in the guidelines, among which 40 (38.1%) believed that implementation obstacles were environmental factors.ConclusionsThe applicability of clinical guidelines for diagnosis and treatment of renal transplantation rejection in China is adequate. However, the publicity of the guideline requires improvement. As the guideline is updated, consideration should be given to including access to the guideline, adding free public information promotion, and familiarizing clinicians with the guidelines through training programs to promote application of the guideline.
Objective To formulate an evidence-based treatment plan for a patient with hepatitis C after kidney transplantation with combination of interferon-α and ribavirin. Methods Based on an adequate assessment of the patient’ s condition and using the principle of PICO, we searched The Cochrane Library (Issue 1, 2009), PubMed (1995 to March 2009), and CHKD (1995 to 2008.12). Results Eighteen studies were identified including 17 in English (5 case reports, 11 cohort studies, and 1 meta–analysis) and 1 in Chinese. According to the current evidence as well as the patient’ s clinical condition and preference, PEG-IFNα-2b 50 μg /week plus ribavirin 600 mg/day was given to the patient for 6 months. Conclusion Evidence-based approaches help us to prepare the anti-viral therapy plan and will improve the assessment of the efficacy and safety in kidney transplantation.
Objective To evaluate the effectiveness and safety of calcineurin inhibitor (CNI) withdrawal from target-of-rapamycin-inhibitor(TOR-I)-based immunosuppression in kidney transplant recipients. Methods We searched MEDLINE, EMbase, SCI, CBM and The Cochrane Library to screen randomized controlled trials (RCT) of calcineurin inhibitor (CNI) withdrawal from target-of-rapamycin-inhibitor-(TOR-I)-based immunosuppression in kidney transplant recipients. The search was updated in Semptember 2009. The quality of the included trials was assessed. RevMan 5.0 software was used for meta-analyses. Results A total of 14 reports from 10 RCTs were identified. Five RCTs were graded A and five graded B. The meta-analyses indicated: RR (95%CI) values of the 1, 2, 4-year acute rejection rates were 1.64 (1.19, 2.27), 1.53 (1.06, 2.22) and 1.21 (0.73, 1.98), respectively; RD (95%CI) values of 1, 2, 4-year patient survival rates were – 0.01 (– 0.02, 0.01), – 0.00 (– 0.03, 0.02) and 0.03 (– 0.01, 0.08), respectively; RD (95%CI) values of 1, 2, 4-year graft survival rates were 0.00 (– 0.02, 0.02), 0.00 (– 0.03, 0.04) and 0.07 (0.01, 0.12), respectively; and glomerular filtration rate WMD was 9.50 and 95%CI 2.96 to 16.03. Conclusion Based on the current evidence, compared to CNI, CNI withdrawal from sirolimus-based immunosuppression in kidney transplantation could be advantageous for renal function. One-year acute rejection rate and 4-year graft survival rate increase. One-year patient/graft survival and fouryear acute rejection rate remain virtually unvariable. The long-term results need further confirmation.
目的 研究無創通氣(NIPPV)治療對腎移植術后巨細胞病毒(CMV)肺炎患者的療效。方法 1998年1月~2005年12月間入住中山大學附屬第一醫院內科重癥監護病房(MICU)的78例腎移植術后CMV肺炎患者，根據是否接受無創通氣治療而分為非NIPPV組和NIPPV組，比較兩組患者在接受有創機械通氣比例、病死率、住院時間及并發癥等方面的差異。對52例NIPPV組患者，比較無創通氣治療前后生命體征及血氣分析指標的變化。結果 NIPPV組與非NIPPV組相比，接受有創機械通氣比例(30.8％ 比80.8％)、醫院獲得性肺炎發生率（32.7％ 比61.5％)及病死率(30.8％ 比57.7％)較低，兩組比較均有顯著性差異(P均lt;0.05)；而住院時間、氣壓傷發生率無顯著差異。NIPPV組患者無創通氣治療后患者呼吸頻率有所減慢，動脈血pH值逐漸降低，PaCO2水平緩慢上升，PaO2、PaO2 ／FiO2及SaO2明顯升高，兩組比較均有顯著差異(P均lt;0.05)。而無創通氣治療前后心率、血壓的變化則無明顯規律。結論 NIPPV治療能夠改善腎移植術后CMV肺炎患者的低氧血癥，緩解呼吸窘迫癥狀，降低有創機械通氣治療比例及醫院獲得性肺炎的發生率，從而降低病死率。用無創通氣治療巨細胞病毒肺炎值得在臨床上推廣使用。
Objective To explore the effect of kidney transplantation on chronic prostatitis-like symptoms. Methods A total of 300 male renal transplant recipients between January 2015 and January 2017 were collected in the study. All recipients received the questionnaire survey of the National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) preoperatively and at 3 months after transplantation. The score and relevant risk factors were statistically analyzed. Results A total of 210 recipients (70.0%) completed questionnaire effectively, in whom 150 (71.4%) had preoperative and 90 (42.9%) had postoperative chronic prostatitis-like symptoms, respectively. In the 210 patients, the preoperative and postoperative pain score was 6.57±3.12 vs. 3.57±3.16 (P<0.001), voiding score was 3.71±2.38vs. 3.29±2.66 (P=0.116), quality of life score was 7.57±1.60 vs. 5.14±2.75 (P<0.001), and the total NIH-CPSI score was 17.86±3.81vs. 12.00±6.65 (P<0.001), respectively. The severity of chronic prostatitis-like symptoms was alleviated significantly after kidney transplantation. Conclusion Kidney transplantation can alleviate the chronic prostatitis-like symptoms significantly, and improve the quality of life in uremia patients.
ObjectiveTo compare the outcomes of kidney transplantation (KT) between Tibetan and Han recipients.MethodsPatients greater than 18 years old, who had received the first ABO-compatible KT between April 2006 and March 2017, were retrospectively included. A propensity score matching (PSM) of Tibetans to Hans was performed by 1∶3 ratio. Survival, renal function and adverse events of the two groups were compared.ResultsOf the 1 820 patients who fit the screening criteria, 123 Tibetans and 357 Hans were included after PSM. The median follow-up time was 48 months. There was no statistically significant difference in death-censored grafts survival (P=0.061) or patients survival (P=0.440) between the two groups. The serum creatinine was higher in Tibetans than that in Hans within one year after KT (P<0.05), and the estimated glomerular filtration rate was lower in Tibetans than that in Hans within 5 years after KT (P<0.05), but no difference thereafter (P>0.05). The incidence of delayed graft function in Tibetan patients after operation was higher than that in Han patients (4.9% vs. 1.4%, P=0.037), but there was no significant difference in the incidence of acute rejection, infection, reoperation, or cancer between the two groups (P>0.05).ConclusionTibetans receiving KT achieve excellent and comparable long-term graft and patient survival to Hans, with similar long-term graft function.
ObjectiveTo conduct a Meta-analysis to determine the clinical effect of protocol biopsy (PB)-monitored therapy after renal transplantation.MethodsPubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Standards Database and VIP Database for Chinese Technical Periodicals were searched for trials comparing the efficacy of timely intervention under PB surveillance with the conventional treatment. The quality of included studies was assessed and Meta-analysis was conducted by RevMan 5.3 software.ResultsSix randomized controlled trials met our inclusion criteria, including 698 cases. No significant difference was found between the PB group and the control group in 1-year [relative risk (RR)=0.99, 95% confidence interval (CI) (0.97, 1.01), P=0.39] and 2-year recipient survival rate [RR=1.00, 95%CI (0.97, 1.02), P=0.72]. Graft survival rate after 1 year [RR=1.01, 95%CI (0.99, 1.04), P=0.29] and 2 years [RR=1.02, 95%CI (0.99, 1.06), P=0.19] were also statistically similar. No statistical difference was found in glomerular filtration rate between the two groups [mean difference (MD)=0.45 mL/(min·1.73 m2), 95%CI (–3.77, 4.67) mL/(min·1.73 m2), P=0.83]. Renal function of PB group, monitored by serum creatinine, was superior to the control group [MD=–0.46 mg/dL, 95%CI (–0.63, –0.29) mg/dL, P<0.000 01]. No statistical difference was found in infection between the two groups [RR=1.23, 95%CI (0.69, 2.19), P=0.48].ConclusionsOur study did not suggest PB for every kidney transplantation recipient. However, long-term randomized controlled trials with larger sample size would be necessary to determine whether PB was effective for specific populations.
Objective To compare the therapeutic effect of new “One-Stitch” ureterovesical anastomosis to that of the classic Lich-Gregoir method. Methods From January 2002 to December 2004, 445 patients suffering from uremia due to chronic nephritis were treated with renal transplantation. Among them, 121 patients were operated with our new modified ureteroneocystostomy technique (the new One-Stitch group), and 324 patients were operated with Lich-Gregoir technique (the Lich-Gregoir group). In the new One-Stitch group, there were 79 males and 42 females, aged 20-62 years (35.7 years on average). The course of the disease was 2-11 years (2.7 years on average). In the Lich-Gregoir group, there were 211 males and 113 females, aged 19-65 years (33.9 years on average). The disease course was 1-14 years (2.3 years on average). There was no significant difference between the two groups in age, proportion of genders, primary diseases and course of the disease (P gt; 0.05). The operative time, the ureteral compl ications and non-ureteral compl ications were compared between the two groups after the renal transplantation. Results The operative time for the new One-Stitch and Lich-Gregoir techniques was (8.7 ± 1.1) minutes and (22.4 ± 5.1) minutes, indicating the difference was significant (P lt; 0.05). All recipients were followed up for 3-5 years. In the new One-Stitch group, there were 5 patients with leakage of urine, 15 with gross hematuria, 4 with ureteral obstruction and 28 with urinary system infection. Symptomatic vesicoureteral reflux and stone formation were not observed in this group. In the Lich-Gregoir group, there were 17 patients with leakage of urine, 12 with gross hematuria, 13 with ureteral obstruction, 86 with urinary system infection, 6 with symptomatic vesicoureteral reflux and 2 with stones. In the new One-Stitch group, the incidence rate of compl ications of gross hematuria was 12.4%, which was significantly different from 3.7% in the Lich-Gregoir group (P lt; 0.05). The incidence rates of ureteral compl ications in the Lich-Gregoir and the new One-Stitch groups were 19.8% and 15.4%, respectively. The difference was not significant (P gt; 0.05). There was no significant difference between the two groupsin incidence rate of urinary system infection, delayed recovery of kidney function after kidney transplantation and rejectionreaction (P gt; 0.05). Conclusion The new One-Stitch group has no significant difference in ureteral compl ications ompared with the Lich-Gregoir group, and has become a preferential ureterovesical reimplantation technique because of its simple and has convenient operation.
