Background: Post-transplant recurrent nephritis is the third common complication that leads to graft loss, which affects the long-term graft survival of kidney transplant patients. Immunoglobulin A nephropathy (IgAN) is the most common for recurrent nephritis, with a recurrence rate of 13–53%. In this study, 12 patients diagnosed with recurrent IgAN were divided into two groups, one which under...
Renal involvement in visceral leishmaniasis (VL) is very frequent but the pathogenesis of this nephropathy is poorly understood. In previous studies using dogs with VL we have detected new immunopathological elements in the glomeruli such as T cells and adhesion molecules. Although Leishmania (Leishmania) chagasi-infected dogs and hamsters are considered to be good models for VL, their use is l...
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 classifi...
The Oxford Classification of IgA Nephropathy (IgAN) identified mesangial hypercellularity (M), endocapillary proliferation (E), segmental glomerulosclerosis (S), and tubular atrophy/interstitial fibrosis (T) as independent predictors of outcome. Whether it applies to individuals excluded from the original study and how therapy influences the predictive value of pathology remain uncertain. The V...
Adipose tissue samples were biopsied from three subcutaneous sites in 80 obese and 27 non-obese patients. Additional samples were taken from intra-abdominal sites in 44 of the patients. There was a small increase in the calculated number of fat cells in the more obese patients, but there was no relation between fat-cell number and obesity of childhood onset. Omental fat cells were one-third the...
We present an unusual case of shunt nephritis in a 39-year-old male who presented 21 years after placement of a ventriculoperitoneal (VP) shunt. He complained of fevers, headaches, dizziness, and urticarial plaques on arms, trunks, and legs and was found to have anemia, low complement levels, elevated serum creatinine, proteinuria, and new onset microhematuria. Blood and urine cultures were neg...
Implication for health policy/practice/research/medical education: It is essential to conduct more studies using a larger number of patients or studies from different geographic parts and ethnicities to obtain the other important prognostic morphologic variables, other than four morphologic variables of Oxford classification.

Endothelium-derived nitric oxide (NO) causes vasodilatation by activating soluble guanylate cyclase, and glomerular mesangial cells respond to NO with elevations of intracellular guanosine 3',5'-cyclic monophosphate (cGMP). We explored whether mesangial cells can be stimulated to produce NO and whether NO modulates mesangial cell function in an autocrine or paracrine fashion. Tumor necrosis fac...
