A 79-year-old woman with familial hyperlipidemia was treated with low-density lipoprotein apheresis. She was hospitalized due to fatigue and edema, and massive proteinuria was discovered. Renal biopsy revealed no distinct abnormalities, thus suggesting a diagnosis of minimal change nephrotic syndrome. She developed acute kidney injury and hemodialysis was initiated. Two series of steroid pulse therapy were given, but the proteinuria did not decrease. Thereafter, she developed thrombocytopenia and fell into a stupor. Thrombotic microangiopathy (TMA) was the most likely diagnosis. Plasma exchange was initiated, resulting in improvements in platelet counts and in her level of consciousness. Clinicians should therefore be aware that TMA can occur as a result of steroid pulse therapy.

Acute infection with Epstein-Barr virus (EBV) causes fever, fatigue and pharyngitis. Renal involvement in systemic EBV infections typically manifests as acute tubular necrosis or tubulointerstitial nephritis. Rarely, EBV infection causes nephrotic syndrome due to minimal change disease. A 22-year-old male with infectious mononucleosis (IM) presented with nephrotic syndrome. Renal biopsy showed minimal change disease with diffuse foot process effacement of the podocytes. Treatment with methylprednisone led to rapid and complete clinical remission. Minimal change nephropathy is a very rare manifestation of EBV infection and should be considered in patients with IM and proteinuria.

Nephrotic syndrome (NS) consists of peripheral edema, heavy proteinuria, and hypoalbuminemia, often with hyperlipidemia. Patients typically present with edema and fatigue, without evidence of heart failure or severe liver disease. The diagnosis of NS is based on typical clinical features with confirmation of heavy proteinuria and hypoalbuminemia. The patient history and selected diagnostic studies rule out important secondary causes, including diabetes mellitus, systemic lupus erythematosus, and medication adverse effects. Most cases of NS are considered idiopathic or primary; membranous nephropathy and focal segmental glomerulosclerosis are the most common histologic subtypes of primary NS in adults. Important complications of NS include venous thrombosis and hyperlipidemia; other potential complications include infection and acute kidney injury. Spontaneous acute kidney injury from NS is rare but can occur as a result of the underlying medical problem. Despite a lack of evidence-based guidelines, treatment consisting of sodium restriction, fluid restriction, loop diuretics, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy, and careful assessment for possible disease complications is appropriate for most patients. Renal biopsy is often recommended, although it may be most useful in patients with suspected underlying systemic lupus erythematosus or other renal disorders, in whom biopsy can guide management and prognosis. Immunosuppressive treatment, including corticosteroids, is often used for NS, although evidence is lacking. Routine prophylactic treatment to prevent infection or thrombosis is not recommended. A nephrologist should be consulted about use of anticoagulation and immunosuppressants, need for renal biopsy, and for other areas of uncertainty.

Minimal change disease (MCD) is an etiology of nephrotic syndrome that is more common in the pediatric population as compared to the adult population. Steroids are an effective treatment for MCD. Non-steroidal anti-inflammatory drugs (NSAIDS) are well known for their nephrotoxicity when used chronically. However, there are only few cases of NSAIDS-induced MCD that have been reported in the literature. Our patient is a 72-year-old male with no significant past medical history who presented with shortness of breath, fatigue, and malaise for few weeks. His renal function was declining in the hospital despite renal protective therapies. His medication history was significant for chronic BC powder (high dose aspirin with caffeine) use. Renal biopsy was performed and showed MCD and acute tubular necrosis. Steroids were initiated and patient's kidney function improved.

Amyloid light chain (AL) amyloidosis is a disease of misfolded, fibrous proteins, either kappa or lambda subtype, that can be deposited into one or more organs, caused by a proliferation of plasma cells. The liver is uncommonly the main organ system affected and rarely the only organ affected by amyloid deposition. With hepatic involvement, the most common presenting findings are hepatomegaly and elevation of serum alkaline phosphatase. We report a case of a 50-year-old male who presented to our gastroenterology clinic with marked hepatomegaly secondary to hepatic amyloidosis, in concert with bone marrow involvement and nephrotic syndrome. Biopsies in conjunction with Congo red staining demonstrated 95% replacement of hepatic structure and 80% replacement of bone marrow with amyloid deposition. Despite these findings, liver chemistries, renal function, and blood count were normal. Our case presents not only the rare finding of primary hepatic amyloidosis but also an atypical presentation of this disorder. Although rare, AL amyloidosis should be in a differential diagnosis of any patient who presents with unexplained hepatomegaly, nephrotic-range proteinuria, heart failure with preserved ejection fraction, fatigue, weight loss or a history of monoclonal gammopathy of undetermined significance.

Relatively little is known about phenotypic variability in nonsyndromic nephropathy associated with the gene encoding the WT1 transcription factor. We report a 12-mo-old female who presented with vomiting, diarrhea, and fatigue in the setting of renal failure and malignant hypertension. Trio ultra-rapid whole-genome sequencing identified a novel, likely pathogenic, de novo missense variant (c.485T > A, p.Val162Asp) in WT1 in 46 h, consistent with a diagnosis of nephrotic syndrome type 4 (NPHS4; OMIM 256370). This disorder typically presents with nephrotic syndrome (gross proteinuria, hypoalbuminemia, and edema). Rapid diagnosis had an immediate impact on her clinical management in the pediatric intensive care unit. Diagnostic renal biopsy was avoided, and placement of permanent dialysis access, a gastrostomy tube, and bilateral nephrectomy were accelerated. This report expands the presenting phenotype of nonsyndromic nephrotic syndrome and/or renal failure due to heterozygous variants in WT1 (NPHS4). It also highlights the relationship between time to genomic diagnosis and clinical utility in critically ill infants.

Membranous nephropathy (MN) is a common glomerular disease that is characterized by diffuse thickening of the glomerular basement membrane, and a common cause of nephrotic syndrome (NS). MN is often accompanied with malignant disease; The solid tumors are commonly associated with MN, whereas hematological malignancies are rarely found in patients with MN. A 68-year-old man with a history of diabetes mellitus visited a hospital with a chief complaint of general fatigue. He was previously not diagnosed with any complications of diabetes. Computed tomography revealed a pancreatic tumor, and the pathological findings of the biopsied tumor revealed the tumor was diffuse large B-cell lymphoma (DLBCL). Concurrently, he developed severe proteinuria, hypoalbuminemia, systemic edema and hyperlipidemia, consistent with the diagnosis of NS. The biopsied renal specimen revealed minute spike lesions of glomerular basement membrane, and abnormal lymphocytes infiltrated in the kidney interstitially. Anti-glomerular basement membrane antibody, proteinase-3-/myeloperoxidase antineutrophil cytoplasmic antibody and hepatitis B antigenemia, are absent in the patient. Serum anti-phospholipase A2 receptor (PLA2R) antibody (marker for primary MN) was not detected. A diagnosis of secondary MN induced by DLBCL was made. He received rituximab containing chemotherapy for DLBCL, resulting in amelioration of both DLBCL and MN. We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN.
