ABSTRACT

Objective:To investigate the clinical application of continuous renal replacement therapy (CRRT) in infants with acute kidney injury (AKI) after liver transplantation.Methods:A retrospective study was conducted on infants with AKI after liver transplantation in Tianjin First Center Hospital from January 1, 2019 to June 1, 2021. Infants with AKI within 1 year after liver transplantation were divided into CRRT group and non-CRRT group according to whether CRRT was performed. The preoperative and intraoperative condition, the postoperative complications were compared, the risk factors of CRRT for AKI infants, the clinical characteristics of CRRT were analyzed, and the prognosis between CRRT group and non-CRRT group were compared.Results:① A total of 512 cases of pediatric liver transplantation were performed. A total of 189 cases (36.9%) developed AKI within 1 year after surgery, including 18 cases in CRRT group and 171 cases in non-CRRT group. ② There was no significant difference in preoperative conditions between the two groups. The duration of liver transplantation (hours: 8.8±1.5 vs. 7.5±1.3) and intraoperative blood loss [mL: 370 (220-800) vs. 310 (200-400)] in CRRT group were significantly higher than those in non-CRRT group. CRRT group had significantly higher incidence of postoperative complication [unplanned operation: 8 cases (44.4%) vs. 14 cases (8.2%), primary nonfunction: 1 case (5.6%) vs. 0 case (0%), retransplantation: 3 cases (16.7%) vs. 0 case (0%), hepatic artery thrombosis: 3 cases (16.7%) vs. 4 cases (2.3%), intestinal fistula: 2 cases (11.1%) vs. 2 cases (1.2%)] than non-CRRT group (all P < 0.05). ③ The average start time of CRRT was 10 (1-240) days. The per capita frequency of CRRT treatment was 3.3 (1.0-14.0) times. The average duration of each CRRT treatment was 10.1 (6.0-19.3) hours, the average reduction rate of serum creatinine (SCr) was 25.6% (13.5%-45.0%) after CRRT. ④ In CRRT group, 5 patients died, the 1-year and 2-year survival rates were both 72.22%. In non-CRRT group, 6 patients died, the 1-year and 2-year survival rates were 97.1% and 96.5%, respectively. There were significant differences in 1-year and 2-year survival rates between the two groups (both P < 0.01). Conclusions:The incidence of AKI after pediatric liver transplantation was high, and most infants treated with CRRT were associated with serious surgical complications. CRRT was a powerful means to remove inflammatory factors and maintain the stability of circulation and internal environment, which could improve the multi-organ dysfunction effectively.

ABSTRACT

Objective To summarize the experience of diagnosis and treatment of Takotsubo syndrome (TTS) after liver transplantation. Methods Clinical data of one TTS patient after liver transplantation was retrospectively analyzed. Clinical features, diagnosis and treatment strategies were summarized, and literature review was conducted. Results A 43-year-old female patient successfully underwent split liver transplantation due to primary biliary cirrhosis for 8 years. At postoperative 3 d, the patient developed anxiety, irritation, dyspnea, disorientation, hypotension, N-terminal pro-brain natriuretic peptide (NT-proBNP) of > 35 000 pg/mL, creatine kinase isoenzyme (CK-MB) of 5.9 U/L and troponin I (TnI) of 1.78 μg/L. Electrocardiogram indicated the signs of sinus rhythm. Echocardiography indicated diffuse weakening of the left ventricular wall motion and spherical dilatation of the apex, accompanied with moderate and severe regurgitation of the mitral valve and tricuspid valve. The left ventricular ejection fraction (LVEF) declined to 23%, whereas no abnormal segmental motion of ventricular wall or corresponding electrocardiogram changes were observed. The possibility of acute coronary syndrome was excluded. The InterTAK diagnostic score was 73. The diagnosis of TTS after liver transplantation was considered. Metoprolol, coenzyme Q10, recombinant human brain natriuretic peptide, deacetyl lanatoside and lorazepam were given. Echocardiography at postoperative 10 d showed that the left ventricular function was significantly improved and the LVEF recovered to 50%. The patient was discharged 40 d after liver transplantation. The liver function was recovered well. During postoperative follow-up, she was given with metoprolol till the submission date, and no recurrence was reported. Conclusions TTS after liver transplantation is rare in clinical practice. It is difficult to make the diagnosis. The condition of TTS is severe and clinical prognosis is poor. Prompt diagnosis and interventions should be implemented.

ABSTRACT

Objective:To study the use of digital subtraction angiography (DSA) guided transnasal ileus tube placement in management of abdominal compartment syndrome (ACS) after liver transplantation.Methods:From January 2015 to December 2019, a total of 30 patients who developed ACS after liver transplantation who were admitted to the Transplantation Intensive Care Unit of Tianjin First Central Hospital were retrospectively studied. According to the way of decompression, these patients were divided into the study group and the control group. Patients in the control group were treated with conventional abdominal decompression, while patients in the study group were treated with DSA guided transnasal ileus tube placement based on management principles developed in conventional abdominal decompression. Changes in intra-abdominal pressure, treatment efficacy rates and liver functions were monitored in the two groups up to 7 days after abdominal decompression.Results:There were 23 males and 7 females, aged (53.4±11.6) years. After treatment, the IAP, portal venous blood flow velocity, bile drainage volume, ALT and AST in the study group were significantly better when compared with the findings before treatment: [IAP: (7.13±3.87) vs (22.73±2.09) mmHg, portal vein blood flow velocity: (34.76±10.31) vs (21.45±6.47) cm/s, bile drainage volume: (198.43±19.94) vs (80.72±9.52) ml/d, ALT: (158.92±67.56) vs (278.73±99.17) U/L, AST: (79.36±15.63) vs (196.71±89.05) U/L], ( P<0.05). After treatment, when compared with the control group, the IAP, portal vein blood flow velocity, bile drainage and TBil in the study group were significantly better [IAP: (7.13±3.87) vs (13.47±6.19) mmHg, portal vein blood flow velocity: (34.76±10.31) vs (24.98±8.54) cm/s, bile drainage: (198.43±19.94) vs (108.73±21.30) ml/d, TBil: (258.85±91.95) vs (343.69±89.45) μmol/L], ( P<0.05). In the control group, the IAP significantly decreased on the fourth day after treatment, ( P<0.05); compared with the significant difference in the study group on the second day after treatment ( P<0.05). After 7 days of treatment, the efficacy rate of the control group was 46.7% (7/15), compared to 86.7% (13/15) in the study group. The difference between the two groups was significant (χ 2=5.400, P<0.05). Conclusion:DSA guided transnasal ileus tube placement for treatment of abdominal compartment syndrome after liver transplantation resulted in a better treatment efficacy rate than conventional treatment.

ABSTRACT

Objective:To explore the application of extracorporeal membrane oxygenation (ECMO)for severe acute respiratory distress syndrome(ARDS)in children after liver transplantation.Methods:The clinical data were retrospectively analyzed for two ECMO-supported children with severe ARDS after liver transplantation. There were suspected pneumocystis carinii pneumonia(n=1)and identified pneumocystis carinii pneumonia(n=1).Results:Veno-arterial ECMO(VA-ECMO)was performed and oxygen saturation index(OSI)before an initiation of ECMO was 31.8 and 23.9 respectively. Both were successfully separated from ECMO after 219 h and 168 h support respectively, and both were weaned from ventilator after 342 h and 232 h invasive mechanical ventilation respectively. The length of ICU stay was 31 and 18 days and the length of hospital stay 57 and 33 days respectively. During ECMO support, liver function remained stable and there was no new onset of organ dysfunction or life-threatening complications.Conclusions:ECMO is a potential therapy for children with severe ADRS after liver transplantation and the assessment and management of complications with ECMO support should be further studied.

ABSTRACT

Objective To analyze the incidence and risk factors of de novo malignant tumors in renal transplant recipients. Methods Clinical data of 1 549 renal transplant recipients were retrospectively analyzed, including the basic status, pathological type and incidence rate of patients with de novo malignant tumors after renal transplantation. The survival situation of these patiensts was assessed. And the risk factors of de novo malignant tumors after renal transplantation were identified. Results The incidence rate of de novo malignant tumors in renal transplant recipients was 3.03%(47/1 549). The 47 recipients were (48±12) years old when undergoing renal transplantation, and they were (55±12) years old when diagnosed malignant tumors. The time interval between transplantation and diagnosis was 66 (36, 100) months. Among the de novo malignant tumors, colorectal cancer was the most common, with a cumulative incidence rate (CIR) of 0.58%. The survival time of 47 recipients with de novo malignant tumors after renal transplantation was 59 (2, 135) months, and the 5-year survival rate was 50%. The recipients with the age > 45 years old when undergoing renal transplantation was a risk factor for de novo malignant tumors after renal transplantation (P < 0.05). Conclusions The incidence rate of de novo malignant tumors is relatively high in renal transplant recipients. The recipients with the age > 45 years old when undergoing renal transplantation is a risk factor for de novo malignant tumors.

ABSTRACT

Hyperammonemia syndrome (HS) is a comparatively rare but often fatal clinical syndrome characterized by progressive respiratory alkalosis and abrupt mental status alteration associated with markedly elevated plasma ammonium levels. Although the exact mechanism of HS remains unclear, infection with urease producing microbes is proposed as the main etiology of HS recently. A patient with HS after repeated autologous skin transplantation was admitted to Tianjin First Center Hospital in March 2018, presented with fever, coma and epilepsy. The infection of Mycoplasma hominis was confirmed in blood sample by high throughput gene detection. The patient was survived after multimodal management including antimicrobial treatment, aggressive ammonia removal by continuous renal replacement therapy in combination with lactulose, and mechanical ventilation. She was successfully discharged from intensive care unit (ICU) with clear consciousness, normal temperature and smooth breath. In view of the experience of the case treatment, a review of literature was conducted to discuss the epidemiology and clinical characteristics, possible etiologies and mechanisms, and outcomes with emphasis on treatment strategies of HS and to promote more clinicians to recognize this rare disease.

ABSTRACT

Objective To review the development of adult and pediatric liver transplantation in Tianjin First Center Hospital, and to enhance academic exchanges, improve technological innovation, and jointly promote the progress and maturity in the field of liver transplantation. Methods The development of liver transplantation in Tianjin First Center Hospital was analyzed. The clinical data of adult and pediatric liver transplantation from September 1998 to September 2018 were collected. The important events and technological innovation achievements of liver transplantation during the 20 years were summarized. Results The first clinical liver transplantation was attempted in Tianjin First Central Hospital in April 1980. The first long-term survival adult liver transplantation in China was completed in 1994 (11 years survival after the operation). The specialized team of liver transplantation was formally established in September 1998. The 20-year clinical exploration and progress reflected the characteristics of era changes and technological innovation during the rapid development of liver transplantation in China. Our center performed liver re-transplantation in January 1999, reduced-size pediatric liver transplantation in August 2000. In May 2001, we organized the formulation for the preventive and treatment plan for hepatitis B recurrence after liver transplantation. We performed combined liver and kidney transplantation in July 2002, split liver transplantation (SLT) in April 2004, the first domino liver transplantation (DLT) in August 2005. Pediatric living donor liver transplantation (LDLT) was initiated in October 2006, adult LDLT was carried out in August 2007. In September 2007, the first living donor combined liver and kidney transplantation from the same donor in Asia was performed. The first domino+living donor double grafts liver transplantation in the world was performed in January 2009. In March 2011, we performed laparoscopically assisted right hepatic lobe liver transplantation (LDLT) with middle hepatic vein. In May 2014, living donor laparoscopic left lateral lobe procurement was successfully established. In April 2016, simultaneous liver, pancreas and kidney multi-organ transplantation was completed. Domino donor-auxiliary liver transplantation was performed in February 2017. In December 2017, extracorporeal membrane oxygenation (ECMO)-supported liver transplantation in a patient with severe pulmonary hypertension was successfully completed. Liver transplantation combined with partial splenectomy was established in April 2018. Cross-domino liver transplantation (hypersensitive kidney transplantation with auxiliary liver transplantation+pediatric liver transplantation) was performed in May 2018. During the 20 years, the team has performed or assisted other centers in Beijing, Shanghai, Guangzhou and Shenzhen to carry out more than 10 000 cases of liver transplantations. A total of 7 043 cases of various types of liver transplantation were performed in the single center of the hospital (6 005 adult liver transplantations and 1 038 pediatric liver transplantations). Concerning adult liver transplantation, the cumulative 1-year, 3-year and 5-year survival rate from September 1998 to March 2003 were 83.1%, 73.0% and 69.0%, from April 2003 to March 2009 were 85.3%, 76.2% and 72.1% and from April 2009 to September 2018 were 87.5%, 79.2% and 75.1%, respectively. The cumulative 1-year, 3-year and 5-year survival rate for pediatric liver transplantation were 93.5%, 92.2% and 90.2%, respectively. The nucleoside (acid) analogue combined with low dose hepatitis B immunoglobulin (HBIG) was developed to prevent the recurrence of hepatitis B after liver transplantation, this plan has reduced the recurrence rate of hepatitis B and the 5-year re-infection rate of hepatitis B virus (HBV) after liver transplantation significantly. The risk assessment system for tumor recurrence after liver transplantation was established and individual treatment method was established based on this assessment system. Continuous exploration and improvement of liver transplantation for liver cancer, liver re-transplantation, liver transplantation with portal vein thrombosis, SLT, DLT and multi-organ combined transplantation have significantly improved the clinical efficacy of patients and the post-operative survival rate. Conclusions The liver transplantation team of Tianjin First Center Hospital has carried out a scientific and technological exploration on the key problems and technical difficulties of clinical liver transplantation. This work strongly has initiated and promoted the rapid development of liver transplantation in China. The restrictive barrier of hepatitis B recurrence after liver transplantation has been overcome. The risk prevention and control system of tumor recurrence after liver transplantation has been established. A series of innovative achievements that can be popularized have been achieved in the field of complex liver transplantation and expansion of donor liver source. The iterative progress and sustainable development of liver transplantation have been realized.

ABSTRACT

OBJECTIVE@#To analyze the characteristics of BK polymavirus (BKV) infection and the optimal time window for intervention in kidney transplant recipients (KTRs).@*METHODS@#We retrospectively analyzed the clinical data and treatment regimens in 226 KTRs in our center between January, 2013 and January, 2018. Among the recipients, 157 had a urine BKV load ≥1.0×10 copy/mL after transplantation, and 69 had a urine BKV load below 1.0×10 copy/mL (control group).@*RESULTS@#Among the 157 KTRs, 60 (38.2%) recipients were positive for urine BKV, 66 (42.0%) had BKV viruria, and 31(19.7%) had BKV viremia. The incidence of positive urine occult blood was significantly higher in BKV-positive recipients than in the control group ( < 0.05). The change of urine BKV load was linearly related to that of Tacrolimus trough blood level (=0.351, < 0.05). In urine BKV positive group, the average estimated glomerular filtration rate (eGFR) was below the baseline level (60 mL·min·1.73 m) upon diagnosis of BKV infection reactivation, and recovered the normal level after intervention. In patients with BKV viruria and viremia, the average eGFR failed to return to the baseline level in spite of improvement of the renal function after intervention.@*CONCLUSIONS@#Positive urine occult blood after transplantation may be associated with BKV infection reactivation in some of the KTRs. BKV infection is sensitive to changes of plasma concentration of immunosuppressive agents. Early intervention of BKV replication in KTRs with appropriate dose reduction for immunosuppression can help to control virus replication and stabilize the allograft function.

ABSTRACT

Clinical data of 113 patients with non-alcoholic fat liver disease (NAFLD) diagnosed by liver biopsy from January 2015 to January 2017 in Taizhou People's Hospital were retrospectively reviewed . Patients all underwent transient elastographic ( TE) examination and the values of fat attenuation index (FAI) were obtained.The hepatocyt fatty changes in pathological examination were scored as 0 (<5%, n=40), 1 (5%-33%,n =27), 2 (34% -66%,n =28) and 3 (>66%, n =18).There were significant differences in AST , Glu, TC and FAI among patients with hepatocyte fatty change scores 0, 1, 2 and 3, and the FAI was significantly correlated with the degree of fatty liver disease .The areas under the ROC curve (AUCs) of FAI in patients with hepatocyte fatty change scores 1, 2 and 3 were 0.78, 0.90 and 0.96, respectively.Logistic regression analysis showed that FAI was correlated with TG , TC and BMI.The results suggest that FAI in TE can be a non-invasive, rapid and objective evaluation method for patients with NAFLD.

ABSTRACT

Objective To discuss the surgical strategy for children with complex congenital heart disease (CHD) and end-stage liver disease (ESLD).Methods We reported two eases of pediatric liver transplantation in patients with complex CHD and ESLD.Medical data including operation procedure,ICU management and outcomes were reviewed retrospectively.Also we reviewed the literature on the topic of clinical outcomes resulted from different surgery options.Results The first case was a seven-month-old male patient with biliary atresia and complex CHD (unroofed coronary sinus syndrome,persistent left superior vena cava,patent foramen ovale,and peripheral pulmonary stenosis).Liver transplantation was successfully performed without corrective heart surgery.The operation time was 6 h and 35 min.The patient suffered acute cardiac dysfunction and significant hypoxemia after extubation,then pneumonia developed,and eventually the patient died on post-operative day 12.The second case was a seven-month-old male patient with biliary atresia and complex CHD (ventricular septal defect,patent foramen ovale,patent ductus arteriosus,pulmonary stenosis).Liver transplantation was performed on the same day following total correction of cardiac defects by open-heart surgery.The operation time was 16 h and 15 min.The patient was extubated after 60 h ventilation,and was transferred to ward from ICU on post-operative day 6 with stable cardiopulmonary function.However,hepatic artery occlusion occurred on early postoperative stage,and consequently the patient received the second liver transplantation for ischemic biliary complication on post-operative day 40.The second liver transplantation procedure was uneventful.The liver graft recovered smoothly with stable hemodynamics.Conclusion Children with complex CHD undergoing liver transplantation are at an increased perioperative risk.The surgical strategy for each patient must be tailored individually according to specific cardiovascular status and limited hepatic reserve.

ABSTRACT

Objective To summarize the clinical course of acute interstitial pneumonitis (AIP) associated pediatric acute respiratory distress syndrome (PARDS) in 8 recipients after liver transplantation,and further discuss the potential risk factors and therapeutic highlights.Methods A total of 476 pediatric patients received liver transplantation in Tianjin First Center Hospital from January 2012 to September 2016.Among them,8 cases of AIP associated PARDS in ICU were recruited in this study.Medical data including clinical presentation,ICU management and outcomes were analyzed retrospectively.Results The onset time-window of AIP associated PARDS was (2.67 ± 0.77) months after liver transplantation,and the time interval between initial symptom and ICU administration was (6.75 ± 5.82) days.Five cases had the history of acute rejection therapy,and 5 cases had CMV and/or EBV viremia history.All 8 cases received mechanical ventilation,2 cases given nasal non-invasive ventilation and the rest 6 cases given invasive ventilation,3 of which were switched to high frequency oscillatory ventilation (HFOV) combined with inhaled nitric oxide.At the stage of hypoxic climax,the fraction of inspired oxygen (FiO2) was up-regulated to 1.0 to maintain the oxygenation index (OI) of (25.24 ± 5.94).Temporary replacement of immunosuppressants with intravenous glucocorticoids was implemented in all 8 cases without acute rejection episode.Of 8 cases,2 cases died from PARDS,1 case died from portal thrombosis associated hepatic failure,and the rest 5 cases survived.Conclusion AIP associated PARDS is a critical complication with high mortality in pediatric patients after liver transplantation.Excessively strong immunosuppression therapy at early post-transplant stage shows a risk factor for AIP.Lung protective ventilation strategy and HFOV are recommended to reduce ventilator induced lung injury in pediatric patients.Temporary intravenous glucocorticoids may reduce acute inflammatory reaction in PARDS patients without increasing the risk of acute rejection.

ABSTRACT

Objective To investigate the therapeutic methods of hyperpotassemia induced by excessively high blood concentration of tacrolimus (FK506) caused by drug use after renal transplantation. Methods Clinical data of 10 patients diagnosed with hyperpotassemia induced by excessively high blood concentration of FK506 after administration of antifunga l medication following renal transplantation were collected and retrospectively analyzed. Results At 1-2 months after renal transplantation, 10 patients suffered from pulmonary infectiono r pneumonia complicated with pulmonary fungal infection . An appropriate dose of compound sulfamethoxazole, micafungin, cefoperazone sodium-sulbactam sodium and moxifloxacin was administered for antifungal infection. After potassium-lowering therapy, termination of antifungal medication and FK506 dose adjustment (replaced by cyclosporin for certain cases), the serum level of potassium was declined and maintained within normal range for 10 cases. The serum concentration of FK506 was within normal range. No sign of excessively high level of potassium was observed without any potassium-lowering intervention. Conclusions Postoperative administration of drugs is likely to cause excessively high level of FK506 and hyperpotasesmia. Potassium-lowering therapy, termination of drug use and adjustment of immunosuppressive agents should be adopted to avoid the incidence of adverse pharmacologic interaction.

ABSTRACT

Objective To explore the effectiveness of octreotide therapeutic strategy to attenuate portal hyperperfusion resulted from small-for-size graft in infant liver transplantation.Methods A total of 22 infants received small-for-size liver graft (defined as GV/SLV<0.5,and GV< 150 g) in our hospital from December 2013 to August 2016.Twelve cases (octreotide group) were treated with intravenous octreotide infusion (300 g daily for 24-96 h) to attenuate the portal hyperperfusion after transplantation,and the rest 10 cases given liver transplantation at the early stage did not receive the intervention of octreotide and served as control group.Results The initial portal vein flows (PVFs) in octreotide group and control group were (413.43 ± 76.24) (390.83 ± 107.89) ml/(min 100 g),and there was no significant difference between two groups (P>0.05).The PVFs on postoperative day (POD) 3 and POD5 in octreotide group and control group were (334.90 ± 96.67) and (441.04 ± 117.41),and (322.20 ± 81.04) and (423.23 ± 100.81) mL/(min 100 g) respectively (P<0.05 for all).However,there were no significant differences in serum AST and bilirubin levels at four time points (initial,POD3,POD5 and POD7) after transplantation between two groups (P>0.05).The incidence of hepatic artery occlusion,and biliary complications in octreotide group and ontrol group was 33.33% and 44.44%,and 33.33% and 11.11% respectively (P > 0.05 for all).Conclusion Octreotide treatment attenuated portal hyperperfusion resulted from small-for-size graft in infant liver transplantation.However,the effects of octreotide therapy on graft biochemical tests,the hepatic artery and biliary complications were still unclear,and further investigation is needed.

ABSTRACT

Objective To evaluate the effect of nasal continuous positive airway pressure (nCPAP) in pediatric patients with respiratory failure after liver transplantation.Method A prospective? randomized controlled clinical trial was conducted during June 1st 2013 to June lst2015 in 71 pediatric patients with respiratory failure after liver transplantation.A total of 66 patients completed the trial and 5 patients quitted.Conventional oxygen therapy group included 35 cases and nCPAP group included 31 cases.The vital sign,blood-gas analysis,intra-abdominal pressure and prognosis were compared between the two groups.Result After nCPAP treatment,the heart rate,respiratory rate,and PCO2 decreased at 4 and 24 h (P<0.05),oxygenation index was improved at 24 and 48 h (P<0.05),and intra-abdominal pressure decreased at 48 h (P<0.05).nCPAP showed better outcome than conventional oxygen therapy (P<0.05).The incidence of refractory atelectasis,intra-abdominal hypertension,and epilepsy was higher in treatment failure population.Conclusion nCPAP is more suitable for pediatric patients with respiratory failure after liver transplantation,especially for those accompanied with intra-abdominal hypertension.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the characteristics of urinary tract infection (UTI) between kidney transplant recipients and non-recipient patients.</p><p><b>METHODS</b>Forty-nine kidney transplant recipients with UTI (69 episodes) and 401 non-recipient patients with UTI (443 episodes) admitted in Nanfang Hospital from January 2003 to August 2014 were enrolled in the study. The characteristics of UTI were compared between two groups.</p><p><b>RESULTS</b>In both groups of UTI, female patients comprised a greater proportion (63.3% and 58.6%) and Escherichia coli was the most common pathogen isolated (37.7% and 34.1%). However, the infection rate of Klebsiella pneumonia in recipients was higher than that in non-recipients (11.6% vs 3.2%, P= 0.001), while the infection rate of Candida albicans was lower (1.5% vs 11.3%, P=0.008) than that in non-recipients. Recipients were likely to develop antibiotic resistance and with a higher recurrence rate than non-recipient patients (38.8% vs 16.7%, P<0.001). Compared to non-recipient UTI patients, the symptoms of urinary irritation in recipient UTI patients were more common. There was higher percentage of neutrophil granulocyte (72.65% ± 1.90% vs 68.59% ± 0.73%, P=0.048), lower proportion of lymphocytes (17.73% ± 1.27% vs 21.28% ± 0.61%, P=0.037), and less platelets [(187.64 ± 10.84) × 10(9)/L vs (240.76 ± 5.26) × 10(9)/L, P<0.01] in recipients than in non-recipient UTI patients.</p><p><b>CONCLUSION</b>These results indicate that the characteristics of UTI in kidney transplantation recipients and non-recipients patients are different.</p>
