Focal segmental glomerulosclerosis (FSGS) is a glomerulopathy associated with nephrotic syndrome and podocyte injury. FSGS occurs both in children and adults and it is considered the main idiopathic nephrotic syndrome nowadays. It is extremely difficult to establish a morphological diagnosis, since some biopsies lack a considerable quantifiable number of sclerotic glomeruli, given their focal aspect and the fact that FSGS occurs in less than half of the glomeruli. Therefore, many biological molecules have been evaluated as potential markers that would enhance the diagnosis of FSGS. Some of these molecules and receptors are associated with the pathogenesis of FSGS and have potential use in diagnosis.

AbstractFocal segmental glomerulosclerosis (FSGS) is a serious condition leading to kidney failure. We aimed to investigate the clinical characteristics of FSGS and its differences compared with minimal change disease (MCD) using cross-sectional data from the Japan Renal Biopsy Registry. In Analysis 1, primary FSGS (n = 996) were stratified by age into three groups: pediatric (< 18 years), adult (18–64 years), and elderly (≥ 65 years), and clinical characteristics were compared. Clinical diagnosis of nephrotic syndrome (NS) was given to 73.5% (97/132) of the pediatric, 41.2% (256/622) of the adult, and 65.7% (159/242) of the elderly group. In Analysis 2, primary FSGS (n = 306) and MCD (n = 1303) whose clinical diagnosis was nephrotic syndrome (NS) and laboratory data were consistent with NS, were enrolled. Logistic regression analysis was conducted to elucidate the variables which can distinguish FSGS from MCD. On multivariable analysis, higher systolic blood pressure, higher serum albumin, lower eGFR, and presence of hematuria associated with FSGS. In Japanese nationwide registry, primary FSGS patients aged 18–64 years showed lower rate of NS than those in other ages. Among primary nephrotic cases, FSGS showed distinct clinical features from MCD.

Nephrotic Range Proteinuria

Physiological proteinuria is common during pregnancy, but pathological proteinuria may also occur. Nephrotic range proteinuria most commonly occurs due to preeclampsia, but primary renal disease may also occur. We present a case of a woman who presented with nephrotic range proteinuria and nephrotic syndrome at an early stage of her second pregnancy. Due to proteinuria, haematuria, progressive symptoms and high need for medical treatment, renal biopsy was performed and she was noted to have focal segmental glomerulosclerosis (FSGS). She commenced immunosuppression but remained nephrotic during pregnancy. She delivered a healthy baby boy at 35 weeks gestation. Postpartum she remained nephrotic, and developed further complications requiring renal replacement therapy. Despite a successful pregnancy, this case of FSGS highlights that despite aggressive treatment FSGS in pregnancy is often associated with adverse renal outcome. We discuss investigations, including renal biopsy and empiric treatment options in this report.

Sjögren‘S Syndrome

Background. Renal tubular acidosis and tubulointerstitial nephritis constitute the primary renal complications associated with Sjögren’s syndrome (SjS), and glomerulonephritis and nephrotic syndrome are rare. Case Presentation. A 79-year-old Japanese woman presented with bilateral leg edema and weight gain and was diagnosed with nephrotic syndrome. In addition, she reported a 5-year history of dryness of mouth and was diagnosed with SjS. Renal biopsy revealed segmental glomerulosclerosis, with some specimens showing collapse of the glomerular capillary loops, proliferation of glomerular epithelial cells, and sclerotic lesions at the tubular poles, without spike formation, double contour lesions, or any other changes of the glomerular basement membrane. Immunofluorescence staining showed no immune complex (immunoglobulin IgG, IgA, or IgM) or complement (C3) deposition in the glomerular capillary walls. Based on these findings, she was diagnosed with focal segmental glomerulosclerosis (FSGS). The administration of steroid and cyclosporine achieved complete remission of nephrotic syndrome. Conclusion. Although glomerular diseases are rare, a variety of glomerular lesions including FSGS are reported in patients with SjS. Therefore, renal biopsy is warranted in patients with SjS presenting with severe urinary abnormalities.

Nephrotic Range Proteinuria

OBJECTIVE: To find out the pattern of glomerulopathies in paediatric population, undergoing renalbiopsy at Khyber Teaching Hospital, Peshawar.METHODS: This was a prospective study carried out at the department of Nephrology at Khyber TeachingHospital, Peshawar from June 2010 till June 2012. Ultrasound guided percutaneous renal biopsies werecarried out in patients with the finding of; 1 ) Nephrotic range proteinuria in children. 2) Non-Nephroticrange proteinuria with evidence of hypertension / haematuria / deranged renal function or active sedimentson urine microscopy. 3) Steroid resistant nephrotic syndrome in children (patients not responding to steroidin eight weeks time) and 4) Children with nephrotic syndrome who were not tolerant of steroid therapy orwere considered for immunosuppressive drugs.RESULT: A total of 155 renal biopsies were done. Out of these 90 were male patients and 65 were females.The most common histopathological lesion among children population was minimal change disease(42.66%) followed by focal segmental glomerulosclerosis (25.33%) and membranous GN (16.0%). Weobserved that nephrotic range proteinuria was most prevalent in minimal change disease and membranousGN followed by focal segmental glomerulosclerosis. While non-nephrotic range proteinuria was mostlyseen in patients with membranoprolifirative GN.CONCLUSION: In paediatric population, minimal change disease is the most common encounteredglomerulopathy, followed by focal segmental glomerulosclerosisand membranous GN.KEY WORDS: Nephrotic syndrome, Renal biopsy, Proteinuria, Glomerulopathy
