RESUMO
Pathogen detection is very important to improve the prognosis of patients with peritoneal dialysis-associated peritonitis. The paper reported a case of peritonitis caused by Ureaplasma parvum diagnosed by metagenomics next-generation sequencing（mNGS）technology. The patient was a middle-aged woman and hospitalized due to abdominal pain and muddy effluent. Anti-infective treatments such as ceftazidime and vancomycin were given but the effect was poor. The result of traditional culture was negative. Ureaplasma parvum was detected by mNGS. After using doxycycline，the patient's inflammation was controlled. It is suggested that mNGS plays an important role in the detection of the pathogens in peritoneal dialysis-associated peritonitis patients with negative culture. Through this case report and literature review，clinical experience is provided for the diagnosis and treatment in such patients.
RESUMO
Objective:To determine whether the early stage platelet count can predict the outcome of peritoneal dialysis-associated peritonitis (PDAP).Methods:A retrospective cohort study was conducted by selecting PDAP patients who were hospitalized in the First People's Hospital of Foshan from January 2012 to January 2019. According to the final treatment outcome, the patients were divided into cured group and withdrawn group. The withdrawn group included patients who transferred to hemodialysis or died. Basic data on demography, blood routine examination, peritoneal fluid, biochemical indicators were compared between the two groups. Logistic regression analysis was used to analyze the withdrawn risk factors of PDAP.Results:There were 180 patients included in the study, including 112 cases in the cured group and 68 cases in the withdrawn group. Compared with the cured group, there were older age [(53.38±14.17) years old vs (48.41±13.04) years old, t=2.407, P=0.017], longer age of dialysis [(49.20±26.05) months vs (30.36±32.97) months, t=4.034, P<0.001], longer hospital stay [(23.88±11.50) d vs (17.80±3.95) d, t=5.133, P<0.001] and higher platelet count [(285.55±107.23)×10 9/L vs (234.90±74.03)×10 9/L, t=3.450, P=0.001], lower serum albumin [(31.72±7.47) g/L vs (35.40±4.93) g/L, t=-3.972, P<0.001] in the withdrawn group. Multivariate logistic regression analysis showed that longer dialysis age ( OR=1.012, 95% CI 1.007-1.024, P=0.015) and higher platelet count ( OR=1.013, 95% CI 1.004-1.026, P=0.008) were independent risk factors, and higher serum albumin ( OR=0.941, 95% CI 0.896-0.988, P=0.005) was an independent protective factor of withdrawal from peritoneal dialysis in PDAP patients. Conclusions:The long dialysis age, early high platelet count are independent risk factors and high serum albumin level is an independent protective factor for withdrawal from peritoneal dialysis in PDAP patients.
RESUMO
Objective To compare the influence of hemodialysis (HD) and peritoneal dialysis (PD) on early outcome of patients underwent kidney transplantation from donation after cardiac death (DCD).Methods Patients admitted in the First People's Hospital of Foshan with DCD kidney transplant from January 1st,2011 to June 30th,2016 were analyzed retrospectively.Recipients were grouped into HD group (n=61) and PD group (n=28) according to their pre-transplant dialysis modality.Their short-term outcomes after DCD kidney transplant were compared,including recovery of renal function,short-term complications and laboratory data.Results Patients had longer dialysis duration and lower hemoglobin,serum albumin and phosphorus in PD group than those in HD group (all P ＜ 0.05),but no significant difference shown in age,gender,body mass index,primary disease,blood pressure,and hepatitis B infection (all P ＞ 0.05).HD patients with 6.00(4.00,11.00) d recovery time of renal function,18.00(17.00,21.50) d hospital time,had 24.59％ the delayed graft function (DGF),3.28％ acute rejection and 16.39％ infection during hospitalization.While for PD patients the recovery time of renal function was 4.00(3.75,7.00) d;hospital time was 19.00(15.00,21.75) d;the incidence rate of DGF was 14.29％;acute rejection was 3.57％;and infection during hospitalization reached 17.86％.Above indexes were not significantly different between HD and PD groups (all P ＞0.05).Repeated measure ments showed that,compared with those before transplant surgery,after 1 month,3 months and 6 months HD and PD groups had decreased creatinine and phosphorus,and increased hemoglobinserum albumin and calcium;Serum albumin and calcium were different between the two groups (P ＜ 0.001,P=0.040),whereas creatinine,hemoglobin and phosphorus did not show difference (all P ＜ 0.05).After transplantation the trends of creatinine,hemoglobin,calcium and phosphorus were not different between the two groups (P values were 0.295,0.310,0.501 and 0.063,respectively).Conclusions No significant difference of the recovery regarding renal function,anemia,nutrition status and mineral metabolites was found between pre-transplant HD and PD modality in patients who underwent DCD kidney transplantations.
