Bullous systemic lupus erythematosus is a rare distinctive subepidermal blistering disorder that can occur in patients with systemic lupus erythematosus (SLE). It is histologically characterized by a neutrophil-predominant infiltrate in the subepidermal region with deposition of immunoglobulins (IgG, IgA, IgM), C3, and auto-antibodies against collagen VII. Herein, we report a case of a 13-year-old girl who presented with bullous SLE and Class III lupus nephritis, which is extremely rare at this age.

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...

Autoimmunity involves immune responses directed against self, which are a result of defective self/foreign distinction of the immune system, leading to proliferation of self-reactive lymphocytes, and is characterized by systemic, as well as tissue-specific, inflammation. Numerous mechanisms operate to ensure the immune tolerance to self-antigens. However, monogenetic defects or genetic variants that weaken immune tolerance render susceptibility to the loss of immune tolerance, which is further triggered by environmental factors...

Systemic lupus erythematosus (SLE) is characterized by a multifaceted pathogenesis and a heterogeneous clinical expression. The kidney involvement is almost unavoidable in all forms of SLE with chronic evolution, 75% of patients developing renal lesions defined as lupus nephritis (LN) - a glomerulonephritis with an extremely diverse lesion spectrum. The present study aimed to reevaluate a series of cases diagnosed as LN, focusing on the histological features in correlation with the level of activity and chronicity...

Though recent reports suggest that neutrophil extracellular traps (NETs) are a source of antigenic nucleic acids in systemic lupus erythematosus (SLE), we recently showed that inhibition of NETs by targeting the NADPH oxidase complex via cytochrome b-245, β polypeptide (cybb) deletion exacerbated disease in the MRL.Faslpr lupus mouse model. While these data challenge the paradigm that NETs promote lupus, it is conceivable that global regulatory properties of cybb and cybb-independent NETs confound these findings...

INTRODUCTION: C1q play an important role in clearance of immune complexes and apoptotic cell debris. Impaired clearance leads to exposure of C1 native antigen and development of anti-C1q antibody formation. Anti-C1q antibody is well studied in Systemic Lupus Erythematosus (SLE). Significance of anti-C1q Ab in Indian SLE patients and their clinical manifestations is not clear. AIM: The aim of this study was to investigate associations between anti-C1q antibody and clinical as well as serological markers of SLE...

Lupus nephritis is a leading cause of mortality among systemic lupus erythematosus (SLE) patients, and its heterogeneous nature poses a significant challenge to the development of effective diagnostics and treatments. Single cell RNA sequencing (scRNA-seq) offers a potential solution to dissect the heterogeneity of the disease and enables the study of similar cell types distant from the site of renal injury to identify novel biomarkers. We applied scRNA-seq to human renal and skin biopsy tissues and demonstrated that scRNA-seq can be performed on samples obtained during routine care...

We investigated whether lupus nephritis (LN) patients could be distinguished based on the time of disease onset and, if so, whether the groups differed in their clinical and laboratory features and long-term prognosis in ethnically homogeneous Korean patients. We enrolled 117 systemic lupus erythematosus patients with available clinical data at the time of renal biopsy of LN. Sociodemographic, clinical, and laboratory data and concomitant diseases were evaluated at the time of renal biopsy. We divided LN patients, according to age at LN diagnosis, into three groups: juvenile-onset LN (JLN, diagnosed at ≤18 years), adult-onset LN (ALN, diagnosed at 18-50 years), and late-onset LN (LLN, diagnosed at >50 years) and compared demographic, clinical, histological, and laboratory findings...

Background.: The role of repeat renal biopsy in lupus nephritis (LN) to guide treatment or predict prognosis has been controversial. We assessed glomerular and tubulointerstitial histological characteristics of serial renal biopsies, correlations with clinical variables and the impact on subsequent management. Methods.: Out of a large single-centre cohort of 270 biopsy- proven LN patients, 66 (24%) had serial biopsies. LN classes based on glomerular pathology were defined according to the International Society of Nephrology/Renal Pathology Society 2003 classification, while tubulointerstitial pathologies were evaluated using the revised Austin's semi-quantitative scoring system...
