ABSTRACT

Objective:To investigate the long-term outcome and prognostic indicators of diffuse pro-liferative lupus nephritis (DPLN).Methods:The primary endpoint of long-term follow-up and factors pos- sibly influencing the outcome were analyzed retrospectively in DPLN patients admitted to the First Affiliated Hospital of Wenzhou Medical University between Jan 1, 2000 and Dec 31, 2014. Patients were classified into three groups according to the evaluated glomerular filtration rate(eGFR) on the first day of admission: eGFR≥60 ml·min -1·1.73 m -2 (regular illness group); 15 ml·min -1·1.73 m -2≤eGFR<60 ml·min -1·1.73 m -2 (serious illness group); eGFR<15 ml·min -1·1.73 m -2 or dialysis (critical illness group). Clinical, histological, and outcome differences among the three groups were evaluated and compared using one-way analysis of variance (ANOVA) , χ2 test, Kaplan-Meier survival curve and Cox reggression analysis. Results:167 DPLN patients were studied [155 women; mean age (30±10) years; mean follow-up of (61±45) months]. Renal and patient survival of all patients was 86% at 5 years and 79% at 10 years. Kaplan-Meier analysis showed the renal and patient survival rate at 10 years in the regular illness group, serious illness group and critical illness group was 91%, 70% and 8%, respectively ( χ2=121.93, P<0.01, overall); regular illness group vs serious illness group ( χ2=4.05, P<0.05); regular illness group vs critical illness group ( χ2=97.05, P<0.01); serious illness group vs critical illness group ( χ2=52.28, P<0.01). Multivariable Cox regression analysis found that haematoglobin (Hb)<80 g/L [ HR=2.7, 95% CI(1.2, 6.3), P=0.019], eGFR<60 ml·min -1·1.73 m -2 [ HR=4.1, 95% CI(2.0, 8.2), P<0.01] and large crescents ≥30%[ HR=1.8, 95% CI (1.1, 2.9), P=0.021], were risk factors for the long-term outcome. Conclusion:DPLN patients with normal or slightly decreased renal function have a better long-term prognosis. Moderate to severe impairment of renal function, anemia and large crescents are associated with poor outcome.

ABSTRACT

Objective To investigate the features of malignancy in end-stage aristolochic acid nephropathy (AAN) patients undergoing renal replacement therapy in the First Affiliated Hospital of Wenhou Medical University.Methods One hundred and two patients diagnosed as end-stage AAN during 2004 to 2013 were enrolled in the study,and separately udergoing hemodialysis,peritoneal dialysis and renal transplantation,to study the features of the malignancy and its risk factors.Results (1) There were totally 42 AAN patients suffering from malignancy,and 39 of them had urinary cancer.Eight cases of urinary cancer had metastasis,and 11 cases of bladder cancer had repeated recurrences.Patients suffering from malignancy had an increased mortality compared to patients without malignancy (13/42 vs 7/60,P =0.022).(2) Thirteen malignacy cases were diagnosed before the end-stage of AAN,the rest cases appeared in 1-13 years[(4.62±3.31) years] after renal replacement.(3) A further logistic regression analysis of the 29 maligancy patients after renal replacement showed that,the dose of aristolochic acid (counted by Mutong) was the only risk factor of malignancy (P =0.091),compared with the dose of Mutong less than 60 g,the patients with an accumulated dose of Mutong more than 200 g had a 4.26 folds (95%CI 1.02,17.83)higher risk of malignancy.There was no statistic difference of the malignancy risk among different renal replacement therapies,which however might influence the pathogenic sites of the urinary cancer.The simple bladder cancer was the most common malignancy among the hemodialysis patients (72.72%),and the upper urinary tract cancer among the peritoneal dialysis patients (66.67%),while the complex of both were dominant among the renal transplantation patients(40.00%).Conclusions Among the end-stage of AAN patients undergoing renal replacement therapy in Wenzhou area,the incidence of urinary cancer is high,with a character of complex,multiple and repeated recurrences.The occurence of malignancy seems to be separated from the renal function,but turns out obviously dose-dependent.There was no statistical difference of cancer risk among hemodialysis,peritoneal dialysis,and renal transplantation,which may induce different pathogenic sites of the urinary cancer.

ABSTRACT

Objective To study the association between Mycoplasma penetrans (Mpe) infection and clinicopathology of IgA nephropathy (IgAN). Methods Blood samples of 118 IgAN patients, 90 patients with chronic kidney disease (CKD) and 89 healthy people were collected. Mpe DNA in serum was detected by PCR and positive samples were confirmed by Southern blotting. According to Mpe infection, IgAN patients were divided into positive and negative groups. Association between clinicopatholgical features of IgAN and Mpe infection was examined.Results Significantly higher Mpe positive rate was found in IgAN group as compared to CKD and healthy groups (16.0% vs 2.2% and 1.1%, P<0.01). In Mpe positive group, 42.1% patients presented macroscopic hematuria, which was significantly higher than that in Mpe negative group (P<0.01). While Mpe negative group had greater proteinuria, higher serum creatinine level, higher Lee grading of pathology compared to Mpe positive group. There were no differences of tubulointerstitial lesions and arteriole hypertrophy between two groups. Conclusions IgAN patients have higher Mpe infection rate than CKD patients and healthy people. Mpe positive IgAN patients have more macroscopic hematuria. Mpe infection may be associated with the pathogenesis of IgAN.

ABSTRACT

Objective To evaluate the efficacy of confocal laser endomicroscopy(CLE)for the assessment of the grading of gastric intestinal metaplasia(GIM)in vivo.Methods Patients with known GIM underwent CLE(Pentax EC-3870K).The presence of GIM was indentified immediately by the endoscopist during the procedure.The updated Sydney Classifycation System as reference,GIM was subdivided as mild,moderate and severe according to the area of intestinal metaplasia glands and the number of goblet cells.The histological evaluation remained the gold standard for the final diagnosis of GIM.The presence of the dysplasia and the expression of the Ki67 were examined.Results A total of 151 GIM positive areas were found in 58 patients with mild in 92,moderate in 34.and severe in 25 by CLE. One hundred and forty-six GIM areas were examined histopathologically with positive rate of 96.7%(mild in 82,moderate in 36 and severe in 28).The sensitivity and specificity of CLE were 90.2%and 73.9%in diagnosis of mild GIM,69.4 oA and 92.2%in moderate GIM,71.4% and 95.9%in severe GIM.The kappa coefficient of CLE criteria and the histopathological grading for mild,moderate and severe GIM were 0.65,0.63 and 0.70,respectively.The more severe the GIM,the higher the ratio of incomplete GIM,the ratio of dysplasia and the stronger expression of Ki67.Conclusions CLE may offer an instant and reliable diagnosis for GIM with high accuracy.It is helpful in grading of GIM.

ABSTRACT

<p><b>OBJECTIVE</b>To understand the prevalence and spatial distribution of vitamin A deficiency (VAD) in China among children at ages under six years.</p><p><b>METHODS</b>About 8,600 children under 6 years of age in 14 cities and 28 counties of 14 provinces were selected with stratified cluster sampling for survey, including interview with questionnaire for their family information and nutritional status. Blood specimens were collected for measuring serum level of VA with fluorescent spectrophotometry in laboratory.</p><p><b>RESULTS</b>Totally, 8,669 children under 6 (2,877 in urban area and 5,792 in rural area) were surveyed in 14 provinces, with 4,629 males and 4,040 females. Eight cases of night blindness and seven cases of xerophthalmia were found among the children at ages of two to five years. Sixty-one mothers of the children in this group were also found suffering from night blindness. All the cases of night blindness and xerophthalmia both in children and mothers were living in rural areas. Based on their serum levels of VA, 11.7% of the all 1 018 children were diagnosed as VAD, with serum VA concentrations below or equal to 0.70 micro mol/L. Prevalence of VAD was 15.0% and 5.8% in rural (23.3% in the poverty-stricken counties) and urban areas, respectively, and 5.8%, 11.5% and 16.8% in the coastal, inland and remote areas, respectively. The average serum level of VA was 1.20 micro mol/L and 0.99 micro mol/L for urban and rural areas, respectively, with a national average of 1.06 micro mol/L. And, babies under six months of age with an average serum levels of VA < or = 0.70 micro mol/L accounted for 33.4%, and those at ages of four to five years with the same level of VA accounted for 8%. There was significant difference in serum levels of VA between ages, but no significant difference between genders.</p><p><b>CONCLUSION</b>VAD did exist in children of China, especially in the remote and poverty-stricken rural areas and VA supplementation is urgently needed for the children in these regions.</p>
