BACKGROUND: We present a patient fulfilling the electrophysiological criteria for definite chronic inflammatory demyelinating polyneuropathy (CIDP), antibody-positive myasthenia gravis (MG), and membranous glomerulonephritis (MGN) confirmed by biopsy. To our knowledge, this is the first case of the concomitant appearance of these three autoimmune diseases in a single patient. CASE REPRESENTATION: A 42-year-old Caucasian male presented with rapidly progressive gait disturbance, distal weakness of the lower extremities, ascending hypoesthesia, impaired fine motor skills, and beginning cranial nerve palsy showing dysarthrophonia, facial paralysis, and eye movement abnormalities and was diagnosed as rapid onset (atypical) CIDP...

REVIEW

Cyclophosphamide is a prodrug that is converted to inactive carboxy-cyclophosphamide, acrolein and phosphoramide mustard, an agent that adds alkyl groups to oxygen and nitrogen atoms of guanine, one of the four nitrogen bases that form the DNA nucleotides, causing DNA cross-links and introducing DNA breaks. These cytotoxic and mutagenic effects mainly occur in proliferating cells. Repair mechanisms may prevent DNA damage in quiescent cells, but they may be insufficient to contrast the side effects of cyclophosphamide if high doses of the drug are used...

Rationale: Late-onset systemic lupus erythematosus (SLE) represents a specific subgroup of SLE, and although there is no strict age cut-off, 50 years is commonly used as the minimum age for disease onset. In this report, we present a case of a 74-year-old male with late-onset SLE and biopsy-proven lupus nephritis (LN). Presenting concerns of the patient: A 74-year-old male was referred to the nephrology clinic with a rapidly rising creatinine from a baseline of 60 µmol/L to 176 µmol/L...

Introduction: Renal biopsy is the principal instrument to evaluate the diagnosis and prognosis of children with kidney disease. There are relatively few studies establishing epidemiology of its findings in the pediatric population. Methods: A descriptive study was conducted to describe characteristics of pediatric patients who had undergone a renal biopsy over the last 10 years in a national reference center, trying to accomplish an etiopathogenic approach of biopsy findings...

Approximately one in four patients (23.3%) with inflammatory myositis including dermatomyositis can require evaluation for acute kidney injury. The main cause of kidney injury is acute tubular necrosis from medications or myoglobinuria, though clinicians should be aware of a wide variety of possible aetiologies. We present the case of a 44-year-old woman with stable anti-Jo1 dermatomyositis, who presented with acute kidney injury. During her hospital course, she was diagnosed with double-positive disease characterised by circulating anti-glomerular basement membrane antibody and myeloperoxidase antineutrophil cytoplasmic antibody and renal biopsy revealing crescentic glomerulonephritis with linear staining of capillary wall for IgG...

BACKGROUND: Membranous glomerulonephritis (MGN) is the most common cause of nephrotic syndrome in adult patients. Despite extensive evidences suggested that many immune-related genes could serve as effective biomarkers in MGN, the potential has not been sufficiently understood because of most previous studies have concentrated on individual gene and not the entire interaction network. METHODS: Here, we integrated multiple levels of data containing immune-related genes, MGN-related genes, protein-protein interaction (PPI) networks and gene expression profiling data to construct an immune or MGN-directed neighbor network (IOMDN network) and an MGN-related genes-directed network (MGND network)...

Nivolumab, an anti-programmed death-1 immune checkpoint inhibitor (ICI), is now widely used to treat numerous cancers. Although most adverse effects related to ICIs are controllable, fulminant immune-related adverse events can occur. A 74-year-old patient with non-small-cell lung cancer was treated with nivolumab as a second-line treatment. After 8 cycles, acute kidney injury with macroscopic hematuria appeared, followed by diffuse ground-glass opacities with hemoptysis. Since the clinical course suggested Goodpasture's disease, methylprednisolone pulse therapy and plasma exchange were started...

Genetic deletion of the Src family tyrosine kinase Lyn in mice recapitulates human systemic lupus erythematosus, characterized by hyperactive BCR signaling, splenomegaly, autoantibody generation, and glomerulonephritis. However, the molecular regulators of autoimmunity in Lyn-deficient mice and in human lupus remain poorly characterized. In this study, we report that conditional deletion of the membrane-cytoskeleton linker protein ezrin in B cells of Lyn-deficient mice (double knockout [DKO] mice) ameliorates B cell activation and lupus pathogenesis...

A 71-year-old woman presented with massive proteinuria and microhematuria. Renal biopsy showed diffuse global membranoproliferative and endocapillary proliferative lesions with leukocytic infiltration and an irregular duplication of the glomerular basement membrane on light microscopy. Immunofluorescence study showed granular deposits of monoclonal immunoglobulin G3 (IgG3) kappa, C3, and C1q in the glomeruli. Electron microscopy revealed unique structurally organized microlamellar electron-dense deposits. There was no evidence of systemic diseases such as paraproteinemia, cryoglobulinemia, or systemic lupus erythematosus...

Renal involvement is the most common extrahepatic manifestation of chronic hepatitis B virus (HBV) infection. While membranous nephropathy is the most frequent, the association with focal segmental glomerulosclerosis (FSGS) is not as strong, and only a few cases have been described in the literature. In particular, the tip variant FSGS is extremely rare and to our knowledge has not previously been described in association with chronic HBV infection. The management of such cases can be challenging. Immunosuppression may lead to enhanced viral replication and flare-up of the hepatic disease...

Native kidney biopsy reports in previous studies that are mostly originated in Western countries show various results in different parts of the world. In this study, we aimed to determine the prevalence of renal biopsy disorders in Iran and compare it with that of other studies in the world. This cross-sectional study evaluated consecutive native kidney biopsies performed in four centers in Isfahan, Iran, from 2009 to 2014. We also reviewed other relevant studies in Iran and the world. Overall, 1547 renal biopsies were reviewed; 493 cases were excluded (transplant or re-biopsy cases) and 1054 cases (43...

Renal cell carcinoma (RCC) comprises 2%-3% of all visceral and 80%-85% of all adult kidney malignancies. Nephrectomy is the treatment of choice for renal tumors. The accurate pathological evaluation of nonneoplastic renal parenchyma in nephrectomy specimens is important for subsequent management. Eighty-two patients with RCC who underwent surgery at Imam Khomeini Hospital, Urmia, Iran, from April 2006 to February 2015 were studied. Paraffin blocks of the hospital archives were stained by hematoxylin and eosin (H and E) and periodic acid-Schiff staining...

The extent of recurrence of original kidney disease after kidney transplantation has been underestimated for several reasons. First, the duration of observation varies among studies. Second, the criteria used to schedule protocol and episode biopsies differ among institutions. And third, diagnostic modalities used for early detection of recurrent original kidney disease also vary. Thus, rates of graft loss attributable to a recurrence of original kidney disease vary among institutions and are often underestimated...

The adult population above the age of 60 years has significantly increased in India, with a life expectancy of 68.4 years in 2016. Data regarding the renal histopathology in these patients are scarce though the number of native kidney biopsies done in this subset of population is increasing. The present study is a retrospective analysis of 231 biopsies from a total of 700 biopsies, from patients above 60 years of age (M = 65.8%; F = 34.2%) with a mean age of 64 ± 6.03 years. The indications for kidney biopsy included nephrotic syndrome (NS) (30...

AIMS: Chronic kidney disease (CKD) is a common complication after liver transplantation (LT). The etiology of CKD is broad and may only be assessed accurately by renal histology. The current study aimed to analyze the safety of renal biopsy in daily clinical practice as well as its usefulness regarding management of CKD after LT. METHODS: We performed a retrospective analysis of clinical data and renal biopsies obtained from patients with severe renal impairment (overt proteinuria, progressive deterioration of renal function) after LT with respect to safety, etiology of renal disease, and therapeutic consequences...
