Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that may affect any organ of the body. We report here an unusual case of seronegative SLE presented as vasculitis with rash, lower gastrointestinal system bleeding and acute renal failure. The patient was a 13-year-old boy, with abdominal distention, pretibial edema, arthritis and petechia on bilateral ankles. He had deteriorated renal functions (creatinine 1.65 mg/dl), hypoalbuminemia (1.6 g/dl) and hypocomplementemia with nephrotic range proteinuria and hematuria. He developed pleural effusion and peritonitis. Serum ANA, anti dsDNA, p ANCA, c ANCA, anticardiolipin IgM and IgG titers were negative. A renal biopsy was performed which revealed diffuse proliferative glomerulonephritis with full-house staining pattern in immunofluorescent microscopic examination suggesting Class IV Lupus Nephritis. He was administered a total of six courses of monthly intravenous pulse methyl prednisolone, dipyridamole, oral cyclophosphamide followed by azothiopirine and oral prednisolone therapy. The renal functions and serum albumin levels turned normal but peritonitis persisted and disappeared after the third pulse steroid therapy. In conclusion, we presented this patient to remind the possibility of SLE in such seronegative patients with unusual findings in order to avoid the delay in the management of this disease with high mortality and morbidity if not treated. Full-house nephropathy is an important clue especially for the diagnosis of ANA negative SLE.

Antineutrophil cytoplasmic antibodies (ANCAs) are associated with small vessel vasculitis but their prevalence is not rare in other immune diseases. In lupus nephritis (LN), their pathological role and clinical relevance have been the target of controversial views. We present a case of acute kidney injury and nephrotic syndrome in a young woman with diffuse global proliferative and membranous nephritis on her kidney biopsy, showing a full-house immunofluorescence pattern, very allusive of class IV + V LN, but lacking associated clinical criteria and laboratory findings to support the diagnosis of systemic lupus erythematosus (SLE). Furthermore, the patient presented with high titers of ANCA, steadily decreasing alongside the renal function and proteinuria improvements, with mycophenolate mofetil (MMF) and steroid treatment. The authors believe this is a case of lupus-like nephritis, in which ANCAs are immunological markers, although they are not directly involved in the pathogenesis.
Delayed onset of systemic lupus erythematosus in patients with ”full-house" nephropathy
Pediatric Nephrology, 1999
Three patients are described who presented with a glomerulopathy suggestive of lupus nephritis in the absence of other clinical and biological evidence of systemic lupus erythematosus (SLE). Renal biopsies showed a "full-house" immunofluorescence pattern and two patients also had cytoplasmic tubuloreticular inclusions by electron microscopy. All these patients developed antinuclear and anti-double-stranded DNA antibodies 3, 5, and 10 years after their original presentation. Subsequently, 1 patient also developed clinical symptoms of lupus. Reviewing all renal biopsies performed in our department, we found 14 additional patients who presented with a "full-house" immunofluorescence glomerulonephritis in the absence of other features of SLE. After a mean follow-up of 5.8 years, these patients have not developed serological or clinical evidence of SLE. We conclude that a "full-house" glomerulopathy in children may be the first symptom of SLE, especially when cytoplasmic tubuloreticular inclusions are detected. The appearance of other clinical and biological symptoms may be delayed by several years.
Renal-limited 'lupus-like' nephritis
Nephrology Dialysis Transplantation, 2011
In the setting of an IgG-dominant immune complex-mediated glomerulonephritis, there are multiple pathological findings that strongly suggest the diagnosis of lupus nephritis (LN) including (i) 'full-house' immunofluorescence staining for IgG, IgM, IgA, C3 and C1; (ii) extraglomerular immune deposits; (iii) combined mesangial, subendothelial and subepithelial immune deposits and (iv) the presence of endothelial tubuloreticular inclusions. We report four female adult patients with renal biopsy findings which are highly suggestive of LN but without extrarenal signs, symptoms or serologies of systemic lupus erythematosus at the time of biopsy or over a mean follow-up period of 3 years. Despite aggressive therapy, outcomes were poor in this small cohort. We refer to these cases as renal-limited 'lupus-like' nephritis.
An Interesting Case of Nonlupus Full-House Nephropathy
Case Reports in Nephrology, 2021
Full-house immunofluorescence and endothelial tubuloreticular inclusions are known as characteristic features of lupus nephritis. However, both features are not pathognomonic for lupus nephritis. A kidney biopsy specimen showing full-house immunofluorescence pattern in the absence of autoantibodies and classical clinical features of Systemic Lupus Erythematosus (SLE) is now considered as nonlupus full-house nephropathy (FHN). Nonlupus FHN may be idiopathic or due to other disease processes known as secondary nonlupus FHN. Here, we report the case of a 36-year-old female who presented with nephrotic proteinuria with bland urine sediment. Additional analyses revealed normal serum antinuclear antibody (ANA), normal anti-double-stranded DNA (anti-dsDNA) antibodies, and normal serum C3 and C4 levels. A renal biopsy showed a normal-appearing glomerulus without any proliferation or capillary wall thickening and widespread glomerular immune deposits (full-house effect; IgA, IgG, IgM, C3, an...
Lupus nephritis with an unusual histopathological pattern
Portuguese Journal of Nephrology & Hypertension, 2021
Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organs. When the kidney is involved it is generally termed lupus nephritis (LN), and is a major contributor to the morbidity and mortality associated with SLE. The classic pattern of lupus nephritis in a renal biopsy is an immune complex mediated glomerulonephritis. The presence of crescents, in diffuse proliferative lupus nephritis, and serologic positivity for antineutrophil cytoplasmatic antibodies (ANCA), more often antimyeloperoxidase than anti-proteinase 3, has been linked with specific clinicopathological features, poor treatment response and a worse kidney survival. Clinical case: We present the case of a 19-year-old male, without relevant past medical history, who presented severe headaches, hypertension and peripheral edema. The blood analysis revealed hemoglobin (Hb) 7.6 g/dL, creatinine (Cr) 2.64 mg/dL, blood urea nitrogen (BUN) 101 mg/dL, and urine analysis, hematuria and ...
Renal-Limited "Lupus-Like" Nephritis: How Much of a Lupus?
Case reports in nephrology and dialysis
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by development of autoantibodies to nuclear and cytoplasmic antigens. A small subset of SLE patients who had the typical clinical features of SLE was reported to show persistently negative antinuclear antibody tests. Our report describes a 5-year-old male who presented with histopathological findings suggestive of lupus nephritis with no clinical signs or symptoms of SLE and negative autoantibodies. He was treated with corticosteroids, mycophenolate mofetil, and monthly intravenous cyclophosphamide. During the 2-year follow-up period, the proteinuria resolved and kidney function improved with continued negative autoantibody workup. This case presents a category of renal-limited "lupus-like" glomerulonephritis which can be challenging to treat and carries a poor prognosis.
Necrotizing and Crescentic Lupus Nephritis with Antineutrophil Cytoplasmic Antibody Seropositivity
Clinical Journal of the American Society of Nephrology, 2008
Background and objectives: Lupus nephritis is a classic immune complex glomerulonephritis. In contrast, antineutrophil cytoplasmic antibodies are associated with necrotizing and crescentic glomerulonephritis, in the absence of significant immune deposits. Antineutrophil cytoplasmic antibodies are detected by indirect immunofluorescence in 20% of patients with systemic lupus erythematosus. We report 10 cases of necrotizing and crescentic lupus nephritis with antineutrophil cytoplasmic antibody seropositivity.
The Various Forms of Nephrotic Syndrome in a Patient with Systemic Lupus Erythematosus
Case Reports in Nephrology, 2020
Kidney involvement is frequent in patients with systemic lupus erythematosus (SLE), although it may not be present from disease onset. Renal lupus itself is highly heterogenous with respect to the combination and/or severity of clinical and/or laboratory manifestations. This is a case of a 45-year-old Caucasian female with an established diagnosis of SLE, who presented four times with new onset of proteinuria during a follow-up time of ten years, since the diagnosis of SLE. Specifically, she experienced two episodes of lupus membranous nephropathy, and after she achieved remission, she developed twice overt nephrotic syndrome associated with new and biopsy proven lupus podocytopathy. All these episodes of nephrotic syndrome were combined with systemic symptoms, attributed to lupus itself, while serological activity of lupus was also noted. This case highlights the importance of performing a kidney biopsy in all patients with SLE who have new renal manifestations, including nephrotic...
