Background: There is a limited knowledge about the morphological features of IgA nephropathy (IgAN)in the middle east region.Objectives: The objective of this study was to evaluate the spectrum of histopathological findings in IgAN patients at our laboratory.Patients and Methods: At this work, an observational study reported which was conducted on IgAN patients using the Oxford–MEST classification system.Results: In this survey, of 102 patients 71.6 % were male. The mean age of the patients was 37.7 13.6 years. Morphologic variables of MEST classification was as follows; M1: 90.2 %, E: 32 %, S: 67 % also,T in grads I and II were in 30% and 19% respectively, while 51% were in grade zero. A significant difference was observed in segmental glomerulosclerosis (P=0.003) and interstitial fibrosis\tubular atrophy frequency distribution (P= 0.045), between males and females . Furthermore, it was found that mesangial hypercellularity was more prevalent in yonger patients. Moreover, there was a significant correlation between serum creatinine and crescents (P0.001). There was also significant correlation of serum creatinine with segmental glomerulosclerosis (P0.001).Conclusions: Higher prevalence of segmental glomerulosclerosis and interstitial fibrosis\ tubular atrophy, as the two of, four variables of Oxford–MEST classification of IgAN in male patients further attests that male gender is a risk factor in this disease.In this study the significant correlation between serum creatinine and crescent was in an agreement with previous studies and suggests for the probable accomodation of extracapillary proliferation as a new variable in MEST system.

Background: Oxford classification for IgA nephropathy (IgAN) did not include pattern of immunostaining in the analysis.Objective: The aim of this study is to determine the potential correlation between the immunostaining data and morphologic variables of Oxford classification (MEST) and various clinical and demographic data of patients with IgAN.Patients and Methods: The pathologic diagnosis of IgAN requires the demonstration of IgA–dominant mesangial or mesangio–capillary immune deposits through immunofluorescence (IF) microscopy. The immune deposits were semiquantitatively assessed as 0 to 3+ positive bright. These were correlated with various clinical, demographic and histological variables of Oxford classification.Results: A total of 114 biopsies were enrolled to the study (70.2% were male). Mean age of the patients was 37.7 ± 13.6 years. This study showed that, only C3 deposits had a significant correlation with serum creatinine. Other antibodies (IgA, IgM and IgG) had no significant association with serum creatinine. This study also showed that IgA deposition score had significant positive association with endocapillary proliferation (E) and segmental glomerulosclerosis (S) variables of Oxford classification. Moreover, IgM deposition score had positive association with S variable. There was no significant association of IgG deposition score with four morphologic variables of Oxford classification. There was significant association of C3 deposition score with S and E variables too.Conclusions: The significant relationships of IgA and C3 deposits with some of the Oxford variables need more attention. We propose to further investigate this aspect of IgAN disease.
