< b > < i > Lautropia mirabilis < /i > < /b > : An Exceedingly Rare Cause of Peritoneal Dialysis-Associated Peritonitis
We present an exceedingly rare case of peritoneal dialysis-associated peritonitis due toL. mirabilis in a patient with a recent history of periodontal infection, successfully treated with intraperitoneal antibiotics. We propose that clinicians consider this organism as a potential cause of illness.Case Rep Nephrol Dial 2022;12:81 –84 (Source: Case Reports in Nephrology and Dialysis)

Interest of a Kidney Biopsy to Rule out ANCA-Associated Renal Vasculitis in Glomerulonephritis Patients with a Positive ANCA
We present a series of 4 cases with a high clinical suspicion of ANCA-associated crescentic glomerulonephritis based on rising serum creatinine, presence of proteinuria and/or hematuria, and presence of ANCA with specificity against PR-3 or MPO. The main diagnosis, however, was arterionephrosclerosis without renal AAV. Certain comorbidities, such as diabetes and/or high blood pressure, can quickly mimic progressive glomerulonephritis. In addition, some patients with AAV do not have high creatinine, proteinuria, or hematuria levels. ANCA alone is not specific to AAV and has a poor positive predictive value. The main concern...

Polyclonal Immunotactoid Glomerulopathy Associated with Monoclonal Gammopathy of IgM Type and Underlying Plasmacellular Disease: Successful Treatment with Rituximab Alone
Immunotactoid glomerulopathy (ITG) occurs infrequently and is characterized by organized IgG containing deposits. It most usually manifests as a concomitant disease of a broad spectrum of oncologic entities. We here present an exceptional case of ITG without glomerular light chain restriction secondary to a IgM kappa type monoclonal gammopathy of undetermined significance. Due to nephrotic syndrome and deterioration of kidney function a rituximab monotherapy was initiated without targeting the plasmacellular augmentation, which was confirmed as the underlying process. The treatment led to a long-term improvement of protein...

Hemodialysis-Related Vision Loss from Anterior Ischemic Optic Neuropathy
Vision loss from nonarteritic anterior ischemic optic neuropathy (NAION) is a rare complication of hemodialysis. Here, we present a case in a young woman and discuss the pathophysiology and implications for the nephrologist. A 24-year-old woman with end-stage renal disease developed unilateral, painless vision loss following treatment with hemodialysis. Fundoscopy revealed severe left inferior chalky-white opticdisc edema, a presentation consistent with NAION. Her intradialytic blood pressure was reviewed and found to be significantly lower than her baseline, and a multidisciplinary meeting took place between her ophthalmo...

Coexistence of Light- and Heavy-Chain Deposition Disease and Immunotactoid Glomerulopathy in a Patient with Multiple Myeloma: A Case Report
Multiple myeloma is a malignant neoplasm leading to a variety of renal diseases. Although most patients have only one pattern of renal pathology, two or more patterns can exist in some patients. Here, we report a 61-year-old man with multiple myeloma developed proteinuria, hematuria, hypertension, and renal insufficiency. A combined presentation of light- and heavy-chain deposition disease and immunotactoid glomerulopathy was proved by kidney biopsy. Treatment of multiple myeloma resulted in a complete resolution of the renal manifestations. This case illustrates the complexity of paraprotein associated renal lesions and e...

De novo Minimal Change Disease in an Adolescent after Pfizer-BioNTech COVID-19 Vaccination: A Case Report
This is the first report in an adolescent of minimal change disease (MCD) after the first injection of the BNT162b2 COVID-19 vaccine (Pfizer-BioNTech) with complete remission following steroid treatment. An 18-year-old white male with no prior medical history complained of gastrointestinal symptoms 11 days after his vaccination. Ascites and lower extremity edema were observed a few days later. He was admitted to a hospital as laboratory testing revealed proteinuria of 10.5 g/24 h, normal creatinine levels, and serum albumin of 1.8 g/dL, confirming the presence of nephrotic syndrome. Immunology and serology tests were unrem...

Minimal Change Disease Secondary to Graft-versus-Host Disease after Allogeneic Hematopoietic Cell Transplant for Myelodysplastic Syndrome
Chronic graft-versus-host disease (cGVHD) is a leading cause of non-relapse mortality in allogeneic hematopoietic cell transplant (HCT) recipients. While the current standard of care is proactive in detecting cGVHD in the lungs, liver, and skin, cGVHD involving kidneys is an underrecognized and likely underdiagnosed cause of post-HCT renal dysfunction. Nephrotic syndrome (NS) is a very rare complication of HCT that is postulated to be a glomerular manifestation of cGVHD. Herein, we report 2 cases of post-HCT minimal change disease likely secondary to cGVHD. In both cases, the onset of NS coincided with tapering of calcineu...

Antineutrophil Cytoplasmic Autoantibody-Associated Glomerulonephritis as a Complication of Home Parenteral Nutrition
Patients on long-term home parenteral nutrition (HPN) occasionally develop glomerulonephritis due to chronic central venous catheter (CVC)-related infection. Most previously reported cases were membranoproliferative glomerulonephritis (MPGN). This is a case report of a 16-year-old girl receiving HPN for short bowel syndrome. After 11 years on HPN, she developed acute kidney injury with macroscopic hematuria, nephrotic-range proteinuria, and a reduced glomerular filtration rate (GFR). Initially, MPGN associated with chronic bacteremia was suspected with the assumption that the condition would be treated with antibiotics and...

Thinking Beyond Acute Kidney Injury
In this report, we present the case of a middle-aged female with no known past medical history who presented with AKI secondary to malignant retroperitoneal fibrosis as the first manifestation of metastatic breast cancer. Her AKI was associated with acute onset anuria and was found to have nondilated postrenal AKI with no significant abnormalities on renal imaging. Early onset anuria in the setting of AKI, which persists despite fluid resuscitation, can suggest complete urinary tract obstruction even with reassuring results of initial renal images, and in the pa tient with no history of cancer screening, malignancy should ...

Genetically Confirmed < b > < i > Edwardsiella tarda < /i > < /b > Peritonitis was Associated with Improper Caregiver ’s Hand Hygiene during Peritoneal Dialysis Bag Exchange
Edwardsiella tarda is a Gram-negative bacillus and is responsible for waterborne disease. This is the first case report of peritoneal dialysis (PD)-associated peritonitis caused by genetically confirmedE. tarda, which was transmitted from the caregiver ’s hand during PD bag exchange. Aside from that, the caregiver was a fishmonger and a gastrointestinal carrier of the pathogen. Prior to the onset of peritonitis, the caregiver reported that she did not wash her hands every time when performing the PD bag exchange. Although extraintestinal edwards iellosis usually poses a poor outcome, PD-associated peritonitis with this s...

Small Bowel Obstruction with a Transition Point in a Patient on Peritoneal Dialysis
We present a case of SBO that was caused by mechanical obstruction from omental adhesions around the PD catheter. This is the case of 71-year-old female with end-stage renal disease who was recently started on PD and presented with recurrent syncopal episodes and altered mental status. During hospitalization, the patient began experiencing incomplete drainage of the PD solution. Abdominal computerized tomography revealed SBO with a transition point near the PD catheter. The patient then underwent laparoscopy, which revealed omental adhesions around the PD catheter near the obstruction area, but no adhesion of the intestine...

Transient Hyperkalemia Following Treatment of Chronic Hypokalemia: A Case Report and Review of Distal Tubule Physiology
Hypokalemia is a relatively common electrolyte disorder usually resulting from gastrointestinal wasting. Transient hyperkalemia in those treated for hypokalemia has been previously described to occur in 16% of hospitalized patients. The majority of those patients had acute, hospital-acquired hypokalemia. Here, we report a case of a young man with alcohol use disorder and chronic hypokalemia who was hospitalized for muscle weakness, abdominal pain, and intractable emesis. His potassium was 2.5 mEq/L on the day of admission. Four days later, with a creatinine at baseline (0.9 mg/dL), potassium abruptly increased to 6.7 mEq/L...
