Tubuloreticular inclusions (TRIs) are subcellular structures located within the cisternae of endoplasmic reticulum. Formation of TRIs has been linked to the exposure of excess interferon (IFN), either from endogenous or exogenous sources. In renal disease, TRIs have been most commonly associated with systemic lupus erythematosus (SLE), and human immunodeficiency virus-associated nephropathy (HIVAN). Case reports of patients with renal biopsies showing TRIs without underlying SLE or HIV are infrequent in adults, and to our knowledge none have been reported in children...

BACKGROUND: In clinical trials, the addition of rituximab (RTX) to the combination therapeutic regimen of mycophenolate mofetil (MMF) and corticosteroids failed to improve outcome in lupus nephritis (LN). However, recent data suggest that RTX may have steroid-sparing beneficial effects with an efficacy similar to that of conventional regimens. We report our experience with RTX in the treatment of children with LN. METHODS: Patients treated with RTX for first occurrence of LN class III to V were enrolled in the study...

BACKGROUND: Best practices for managing childhood-onset membranous lupus nephritis (MLN) are not yet established. Most studies involve primarily or exclusively adult cohorts or pediatric cohorts with combinations of pure or mixed membranous and proliferative nephritis. METHODS: We performed a single-center cohort study of consecutively diagnosed children with pure MLN from 1990 and 2016. Patients received care in Houston, Texas, one of the most diverse metropolitan areas in North America...

INTRODUCTION: Systemic lupus erythematosus is an autoimmune disease in which the severity varies according to race, sex and age of onset. This variation is also observed in the genetic markers associated with the disease, including PTPN22, VDR and TNF genes. The genetic stratification in different populations worldwide can influence the variability. OBJECTIVE: To analyze the heritability of PTPN22, VDR and TNF genetic variants and their association with pediatric lupus nephritis in Colombian families...

BACKGROUND: BK virus (BKV) is a ubiquitous polyoma virus that lies dormant in the genitourinary tract once acquired in early childhood. In states of cellular immunodeficiency, the virus can reactivate to cause hemorrhagic cystitis and nephritis. Children with systemic lupus erythematosus (SLE) have an increased risk of developing infectious complications secondary to their immunocompromised state from the administration of several immuno-modulatory drugs. Currently, there are no data regarding the prevalence of BK viruria or viremia in children with SLE...

Lupus nephritis (LN) is one of the major clinical manifestations of systemic lupus erythematosus (SLE) which occurs frequently in the early stages of pediatric-onset cases. Since SLE is a chronic disease associated with frequent disease flares and effective and safe maintenance therapy is required for achieving a favorable outcome, optimal treatment for LN in pubertal patients is a great challenge that remains to be overcome. Although its etiology remains unclear, it has been reported that the innate and adaptive immune systems have been reported to play an important role in the pathogenesis of SLE...

BACKGROUND: Childhood-onset lupus nephritis (LN) is one of the most severe manifestations of systemic lupus erythematosus (SLE). Despite treatment-related toxicities, cyclophosphamide (CYC) and glucocorticoid-based treatment protocols are still considered standard therapy in managing this multisystem disorder. An effective and safe alternative induction regimen is needed. METHODS: Forty-four pediatric patients with active LN aged 3.5-13.8 (median 8.4) years, of whom 32 entered the study at diagnosis of SLE, were followed over 36 months...

Nearly 20% of SLE corresponds to the pediatric population, and 75% of them have kidney involvement representing an important etiology of chronic kidney disease. A correlation between SLE and ANCA-associated vasculitis has been identified as an overlapping syndrome. Kidney allograft recurrence is rare in SLE when disease control is achieved and with nowadays immunosuppression treatment. Histologic transformation is unusual, especially when there are negative serologic markers and no immune complex deposition reported in native kidneys...

The discovery of serum biomarkers specific for paediatric lupus nephritis (pLN) will facilitate the non-invasive diagnosis, follow-up and more appropriate use of treatment. The aim of this study was to explore the role of serum high-mobility group box 1 (HMGB1) protein, antibodies against nucleosomes (anti-NCS), complement factor C1q (anti-C1q) and glomerular basement membrane (anti-GBM) in pLN. Serum samples of 42 patients with paediatric systemic lupus erythematosus (pSLE) (22 with pLN and 20 without renal involvement), 15 patients with other autoimmune nephritis (AN) and 26 healthy controls (HCs) were examined using enzyme-linked immunosorbent assay (ELISA)...

A 9-year-old female child was initially diagnosed of having nephrocalcinosis with distal renal tubular acidosis (dRTA) while investigating for short stature. She later on developed features of nephrotic syndrome (NS) while on treatment for RTA. Investigation for the cause of NS revealed very strong serological evidence in favor of systemic lupus erythematosus (SLE). Histopathological confirmation could not be done due to bilateral severely contracted kidneys. There are a few case reports of dRTA as the presentation of SLE, but nephrocalcinosis with dRTA with subsequent manifestation of SLE has hitherto not been reported in literature...

Lupus nephritis is identified in up to 75% of patients with juvenile systemic lupus erythematosus and may present with abnormal urinary findings (overt lupus nephritis) or be apparent only upon renal biopsy (silent lupus nephritis). We investigated whether serum complement levels correlate with renal pathology in pediatric patients with silent lupus nephritis. We performed baseline renal biopsy in 45 children diagnosed with juvenile systemic lupus erythematosus who were admitted to Kagoshima University Hospital between January 2000 and June 2015...

The care of children with lupus nephritis (LN) has changed dramatically over the past 50 y. The majority of patients with childhood-onset systemic lupus erythematosus (cSLE) develop LN. In the 1960's, prognosis in children was worse than in adults; therapies were limited and toxic. Nearly half of cases resulted in death within 2 y. Since this time, several diagnostic recommendations and disease-specific indices have been developed to assist physicians caring for patients with LN. Pediatric researchers are validating and adapting these indices and guidelines for the treatment of LN in cSLE...

INTRODUCTION: Epithelial-mesenchymal transition (EMT) is a process in which epithelial cells may express mesenchymal cell markers with subsequent change in their functions, and it may be part of the etiopathogenesis of kidney disease. OBJECTIVE: The aim of this study was to evaluate the immunexpression of some EMT inducers and markers in frequent nephropathies in pediatric patients. METHODS: 59 patients aged 2-18 years old were selected and divided into 6 groups of frequent nephropathies in children and adolescents, as well as one control group...
