Clinical and pathological analysis of patients with primary mesangial proliferative glomerulonephritis in different genders / 中国综合临床

ABSTRACT

Objective To understand the differences between sexes in the clinical and pathological features of patients with mesangial proliferative glomerulonephritis(MPGS).MethodsOne hundred and five patients with MPGS admitted to our hospital were retrospectively studied in clinical and pathological aspects.Results( 1 ) The proportion of male patients were 75 of 105 ( 71.43 ％ ) and that of females were 30 of 105 ( 28.57％ ) ; ( 2 ) The average age of the male patients was ( 40.25 ± 15.50 ) and that of the females was (36.23 ± 15.26) in year.There was no significant difference between the two groups( t =1.206,P =0.231 ) ;(3) There was no significant difference in duration of disease,hematuria,edema,hypertension prevalence and mean blood pressure( P ＞ 0.05 ).The proportion of patients with hematuria was 56.19％ (59/105).The males accounted for 69.33％ ( 52/75 ) and the females were 63.33％ ( 19/30 ) in the main clinical manifestations of nephrotic syndrome.There was no significant difference( x2 =0.352,P ＞ 0.05 ) between the proportion of males and females; (4)Males and females groups had no significant difference( P ＞ 0.05 )on levels of urinary protein,serum albumin,immunoglobulin,complement,urea nitrogen and serum creatinine.Complement decreased in 53 cases,accounting for 53％ of all the participants.The proportion of male patients with renal insufficiency was 24.00％ (18/75),and the proportion of females with renal insufficiency was 13.33％ (4/30).There was no significant difference ( x2 =1.472,P ＞ 0.05 )on the percentage of males and females with renal insufficiency.The mean value of urea nitrogen was higher than the normal levels ; (5) The proportion of male cases with different deposition of immune complexes was 93.06％ (67/72),and the proportion in females were 92.86％ (26/28) in the exception of 5 cases ( male 3 and female 2 ) with no glomeruli in immunofluorescence examination.No significant difference was found between the two groups( x2 =0.001,P ＞ 0.05 ) ; ( 6 ) There was no significant gender differences( x2 =1.696,P ＞ 0.05 ) found in risk assessment.ConclusionThe prevalence of MPGS is higher in male patients than in females,the main clinical manifestations of which were nephrotic syndrome.Patients were found to have a higher rate of hematuria,decreased complement C3,and renal dysfunction than the normal levels.There was no significant difference in gender on the clinical and pathological aspects of MPGS.
