Two preterm infants, with extremely low birth weight born at gestational weeks 24 and 25, showed generalized proximal tubular dysfunction during their stay in the neonatal intensive care unit, including glucosuria, low molecular weight proteinuria, phosphaturia, uricosuria, enzymuria (elevated urine N-acetyl-β-D-glucosaminidase), panaminoaciduria, and hypercalciuria, associated with renal calcification. Renal tubular acidosis was not present in either patient. DNA mutation analysis for Dent's disease, performed in patient 1, was negative...

INTRODUCTION: The toxic effects of the ingestion of star fruit (Averrhoa carambola) in chronic kidney disease patients are well described in the literature. Recently, the compound caramboxin has been isolated, explaining the mechanisms of its neurotoxicity. Bilimbi fruit belongs to the family Oxalidaceae, Averrhoa bilimbi species, and exhibits similar biochemical characteristics to star fruit. OBJECTIVE: To report the case of a patient with chronic kidney disease who developed a seizure disorder after the ingestion of bilimbi fruit...

Recurrence of focal segmental glomerulosclerosis (FSGS) after renal transplantation occurs in up to 20-50% of FSGS patients and is associated with inferior allograft survival. Treatment of both primary FSGS as well as recurrent FSGS after transplantation with plasma exchange and immunosuppression is often unsuccessful and remains a major challenge as the disease still leads to end-stage renal disease and decreased graft survival. Previous case reports have described patients with recurrent FSGS who were successfully treated with a B7-1 inhibitor (abatacept) inducing partial or complete remission...

Pregnancy-associated thrombotic microangiopathy is a very rare condition; however, it significantly increases fetal or maternal morbidity and mortality. Pregnancy may trigger atypical hemolytic uremic syndrome (aHUS) or thrombotic thrombocytopenic purpura. The risk for pregnancy-associated aHUS is highest during the second pregnancy. The outcome is usually poor with 50-60% mortality; renal dysfunction and hypertension are the rule in those who survive the acute episode. After the development of complement regulation mechanisms and aHUS pathogenesis, eculizumab has been widely used as a first-line treatment in aHUS...

We report a case of glomerulopathy in a 36-year-old Japanese woman with primary Sjögren syndrome (pSS). The first renal biopsy suggested membranous glomerulonephritis. However, repeat biopsy was performed after 16 years because of increased proteinuria, revealing membranoproliferative glomerulonephritis with mesangial deposits, subendothelial deposits, and subepithelial deposits. Immunofluorescent studies showed predominant deposition of IgG2 and IgG4. This patient was positive for antinuclear antibody and anti-SS-A antibody...

The usual manifestation of brachial artery aneurysms is the incidental finding of a swelling of the arm, combined with paresthesia or pain in some cases. The etiology is often traumatic or secondary to drug abuse. Pathophysiology of brachial artery dilation in these cases is not completely clear. We herein describe a case of a 61-year-old male presenting with a giant, painful, pulsatile mass on his left arm. He was submitted to a cadaveric kidney transplant in 2005. He had a functioning arteriovenous fistula (AVF) on his right arm, and a spontaneously thrombosed radiocephalic AVF on his left arm...

Hemolytic uremic syndrome (HUS) is defined by the simultaneous occurrence of hemolytic anemia, thrombocytopenia, and acute kidney injury due to thrombotic microangiopathy (TMA) mainly occurring in renal and cerebral microvessels. Although the most common cause of HUS in children is Shiga toxin-producing Escherichia coli, atypical forms in which Shiga toxin is not the trigger may occur. Research over the last few years has shown that complement dysregulation secondary to mutations of genes coding for proteins involved in the regulation of the alternative pathway of complement account for most forms of atypical HUS (aHUS)...

Hyperoxaluria after Roux-en-Y gastric bypass (RYGB) increases the risk for kidney injury. Medical therapies for hyperoxaluria have limited efficacy. A 65-year-old female was evaluated for acute kidney injury [AKI, serum creatinine (Cr) 2.1 mg/dl, baseline Cr 1.0 mg/dl]. She did not have any urinary or gastrointestinal symptoms or exposure to nephrotoxic agents. Sixteen months prior to this evaluation, she underwent RYGB for morbid obesity. Her examination was unremarkable for hypertension or edema and there was no protein or blood on urine dipstick...

Many types of inherited renal diseases have ocular features that occasionally support a diagnosis. The following study describes an unusual example of a 40-year-old woman with granular corneal dystrophy type II complicated by renal involvement. These two conditions may coincidentally coexist; however, there are some reports that demonstrate an association between renal involvement and granular corneal dystrophy type II. Granular corneal dystrophy type II is caused by a mutation in the transforming growth factor-β-induced (TGFBI) gene...

We report the case of a 22-year-old African American female who presented to another facility for routine follow-up in the 34th week of pregnancy with lower extremity swelling and nephrotic-range proteinuria. Although she was normotensive, it was initially thought that she had preeclampsia. She was monitored carefully and delivery was induced at 37 weeks of gestation. She was transferred to our hospital, where she was diagnosed with systemic lupus erythematosus (SLE) based on clinical and laboratory criteria...

Although Brucella species is known to affect almost all organs in humans, renal involvement presenting as acute pyelonephritis remains a rare entity in brucellosis. We report the case of a female patient who presented with symptoms of fever with chills, right loin pain and dysuria in the emergency room. Blood cultures drawn at the time of admission grew Brucella spp., but no organisms were isolated from urine culture although urinalysis data was indicative of urinary tract infection. Empiric therapy with piperacillin/tazobactam plus gentamicin relieved her symptoms...

Renal failure and infectious disease are strongly associated with morbidity and mortality in patients with severe generalized recessive dystrophic epidermolysis bullosa (RDEB-sev gen). However, it is reportedly difficult to introduce hemodialysis with an arteriovenous fistula (AVF). We encountered a 32-year-old man with RDEB-sev gen in whom hemodialysis with a native AVF was introduced that favorably affected his long-term survival. This patient eventually died because of cachexia related to the recurrence of cutaneous squamous cell carcinoma 51 months after hemodialysis introduction...

INTRODUCTION: IgG4-related disease (IgG4-RD) is a fibroinflammatory disorder that may involve almost each organ or system. IgG4-related kidney disease (IgG4-RKD) refers to renal lesions associated with IgG4-RD. The most frequent morphological type of renal lesions is IgG4-related tubulointerstitial nephritis (IgG4-TIN) which is associated with increased IgG4-positive plasma cell infiltration and interstitial fibrosis. CASE REPORT: Herein, we present a rare case with coexisting IgG4-RKD and acute crescent glomerulonephritis with concomitant severe tubulointerstitial lesions instead of classic IgG4-TIN...

A 95-year-old woman was admitted to our hospital for evaluation of bilateral lower-limb edema persisting for 3 months. Serum creatinine was 1.55 mg/dl, and urinary protein excretion was 9.1 g/day. Renal biopsy revealed stage 1 membranous glomerulonephritis (MGN) with immunoglobulin G4-dominant staining. This patient did not have any underlying disease such as infection with hepatitis B or C virus or malignancy, and anti-phospholipase A2 receptor (PLA2R) antibody was detected in the serum. Accordingly, idiopathic MGN was diagnosed...

The anti-CD20 monoclonal antibody rituximab is associated with rare but significant adverse events, notably posterior reversible encephalopathy syndrome (PRES) and acute respiratory distress syndrome (ARDS). We report a case of concomitant ARDS and PRES developing after rituximab therapy for treatment of cryoglobulinaemic vasculitis. There are 7 reported cases of PRES complicating rituximab use. PRES onset varied from immediate to 21 days after administration. All patients recovered completely, and rituximab was reintroduced in half of the cases...

Acute postinfectious glomerulonephritis (PIGN) affects children typically after upper respiratory tract or skin infections with streptococci but can complicate the course of other infections. In children, it is generally a self-limiting disease with excellent prognosis. This paper reports a previously healthy 4-year-old boy who experienced a protracted course of PIGN with persisting episodes of gross haematuria, proteinuria, decreased complement C3c levels but normal P-creatinine levels. Due to the protracted course and the nephrotic-range proteinuria, a renal biopsy was performed 6 months after the initial presentation and the overall pathology was consistent with acute endocapillary glomerulonephritis...

A common renal phenotype of paired box protein 2 (PAX2) mutations is renal coloboma syndrome. We report a single family with diverse renal phenotypes associated with PAX2 mutation. The proband presented steroid-resistant focal segmental glomerulosclerosis with optic coloboma, whereas his two sons showed severe renal hypoplasia with end-stage renal disease, with or without optic coloboma. In all three cases, a heterozygous PAX2 genetic mutation was identified (exon 2; NM_003987.3:c.76dupG, p.Val26Glyfs*28). Based on histopathological findings of the proband, we hypothesized that autophagic dysfunction was associated with the pathophysiology of the focal segmental glomerulosclerosis with PAX2 mutation...

Focal segmental glomerulosclerosis (FSGS) causes glomerular lesions that can progress to end-stage renal disease. It is suspected to be caused by a circulating factor that is amenable to plasmapheresis removal and exhibits a risk for recurrence in the renal allograft. We present two patients with FSGS recurrence in their allograft kidneys diagnosed by biopsy after significant proteinuria developed in the posttransplant setting. Treatment with therapeutic plasma exchange induced long-term remission in both patients...

Brown tumors are focal bone lesions, encountered in patients with uncontrolled hyperparathyroidism. They can be located in any part of the skeleton. Clinically significant lesions in the craniofacial bones are rare. Craniofacial involvement may cause facial disfiguration and compromise social ease of the patient and normal functions, such as chewing, talking, and breathing. In this case report, we present a patient with a brown tumor of the craniofacial bones provoked by secondary hyperparathyroidism and review the last 10 years of craniofacial brown tumors associated with secondary hyperparathyroidism in the English literature...

We encountered 2 cases of hypophosphatemia due to Legionella pneumonia. Both cases showed increased urinary phosphate excretion and renal tubular dysfunction, which ameliorated with recovery from Legionella pneumonia. Serum fibroblast growth factor-23 level was suppressed, whereas serum 1,25(OH)2 vitamin D and parathyroid hormone levels were normal. Delayed elevation of serum 1,25(OH)2 vitamin D levels was observed with improvement in renal tubular function. These findings suggested hypophosphatemia might be mediated by renal tubular dysfunction...
