LMX1B-associated nephropathy that showed myelin figures on electron microscopy.

CEN Case Rep 2021 Jun 2. Epub 2021 Jun 2.

Department of Nephrology, Tokyo Medical University Ibaraki Medical Center, 3-20-1 Chuo Ami, Inashiki, Ibaraki, 300-0395, Japan.

The mutation of LIM homeodomain transcription factor LMX1B gene leads to nail-patella syndrome (NPS), which is characterized by dysplastic nails, hypoplastic patellae, iliac horns and nephropathy. The characteristic renal histological finding of NPS nephropathy is irregular thickening of the glomerular basement membrane with patchy lucent areas, including deposits of bundles of type III collagen fibrils revealed by electron microscopy (EM). Fabry disease is a lysosomal storage disorder caused by a deficiency of α-galactosidase A activity, and the characteristic EM finding is a lamellated membrane structure (myelin figures). Read More

From Skin to Kidneys: Cutaneous Clues of Renal Disease in Children.

Dermatol Pract Concept 2020 Oct 26;10(4):e2020095. Epub 2020 Oct 26.

Dermatology Unit, University of Campania Luigi Vanvitelli, Naples, Italy.

Background: The skin is often seen as a world apart, but not rarely do cutaneous manifestations reveal signs of systemic disease.

Objectives: The aim of this review is to include in one paper all the possible correlations between nephrological and dermatological manifestations of the same disease in pediatric patients while also keeping in mind that in apparent exclusively dermatological diseases there can be nephrological manifestations as part of the same disorder and vice versa.

Methods: We searched on PubMed for a possible link between skin and kidney matching the following terms and correlated MeSH terms: dermatology, skin, kidney, renal disease, nephrology, pediatrics, child, childhood, vasculitis, and cancer. Read More

Telmisartan alleviates collagen type III glomerulopathy: A case report with literature review.

Exp Ther Med 2020 Dec 5;20(6):140. Epub 2020 Oct 5.

Department of Nephrology, The Second Hospital of Jilin University, Changchun, Jilin 130041, P.R. China.

Collagen type III is commonly detected in the renal interstitium and vasculature; however, it is absent in healthy glomeruli. Deposition of collagen type III in the glomerular mesangium and capillary basement membranes may arise in two rare diseases, namely collagen type III glomerulopathy (CG) and nail patella syndrome. CG is a rare glomerular disease with no specific treatment, although supportive measures for control of hypertension and edema may help to relieve symptoms. Read More

Unidad de Investigación, Hospital Universitario Nuestra Señora de Candelaria, 38010 Santa Cruz de Tenerife, Spain.

Nail-Patella syndrome (NPS) is an inherited disease characterized by nail and skeletal anomalies, nephropathy and glaucoma. The diagnosis of NPS is based on clinical findings, including hypoplastic or absent patella, dystrophic nails, dysplasia of the elbows and iliac horns. However, the main determinant of NPS prognosis is nephropathy, which may range from asymptomatic proteinuria to end-stage renal disease. Read More

Nail-patella-like renal disease masquerading as Fabry disease on kidney biopsy: a case report.

BMC Nephrol 2020 08 13;21(1):341. Epub 2020 Aug 13.

Division of Nephrology and Hypertension, Department of Medicine, Mayo Clinic, 200 First St SW, Rochester, MN, 55905, USA.

Background: Genetic changes in the LIM homeobox transcription factor 1 beta (LMX1B) have been associated with focal segmental glomerulosclerosis (FSGS) without the extra-renal or ultrastructural manifestations of Nail-patella syndrome (NPS) known as Nail-patella-like renal disease (NPLRD). Fabry disease (FD) is an X-linked lysosomal disease caused by the deficiency of alpha-galactosidase A. The classic form of the disease is characterized by acroparesthesia, angiokeratomas, cornea verticillata, hypertrophic cardiomyopathy, strokes, and chronic kidney disease. Read More

Case Rep Nephrol 2020 24;2020:8879555. Epub 2020 Jul 24.

Nephrology Service, Hospital Británico de Buenos Aires, Buenos Aires, Argentina.

Focal and segmental glomerulosclerosis (FSGS) is a histopathological pattern of injury. As such, it encompasses a wide variety of dissimilar entities with different pathophysiologic mechanisms. Although ultrastructural morphological characteristics can specifically diagnose certain diseases and genetic mutations can also be unravelled, this ideal situation is generally not available worldwide.

Clinical and genetic characterization of nephropathy in patients with nail-patella syndrome.

Eur J Hum Genet 2020 10 26;28(10):1414-1421. Epub 2020 May 26.

Department of Pediatrics, Graduate School of Medicine, The University of Tokyo, Tokyo, Japan.

Nail-patella syndrome (NPS) is a multi-system disorder characterized by hypoplastic nails, hypoplastic patella, skeletal deformities, and iliac horns, which is caused by heterozygous variants of LMX1B. Nephropathy ranging from mild urinary abnormality to end-stage renal disease occurs in some individuals with NPS. Because of the low prevalence of NPS and the lack of longitudinal studies of its kidney involvement, the clinical, pathological, and genetic features characterizing severe nephropathy remain unclear.

Myelin bodies in LMX1B-associated nephropathy: potential for misdiagnosis.

Pediatr Nephrol 2020 09 30;35(9):1647-1657. Epub 2020 Apr 30.

Department of Pathology, Stanford University, H2110, 300 Pasteur Drive, Stanford, CA, 94305, USA.

Background: Myelin figures, or zebra bodies, seen on electron microscopy were historically considered pathognomonic of Fabry disease, a rare lysosomal storage disorder caused by alpha-galactosidase A deficiency and associated with X-linked recessive mode of inheritance. More recently, iatrogenic phospholipidosis has emerged as an important alternate cause of myelin figures in the kidney.

Methods: We report two families with autosomal dominant nephropathy presenting with proteinuria and microscopic hematuria, and the kidney biopsies were notable for the presence of myelin figures and zebra bodies. Read More

A Double Case of Nail-Patella Syndrome in the Same Family: The Importance of Nail Changes as Diagnostic Clues for Renal Involvement.

Skin Appendage Disord 2019 Nov 10;5(6):405-408. Epub 2019 Jul 10.

Department of Experimental, Diagnostic and Specialty Medicine, Division of Dermatology, University of Bologna, Bologna, Italy.

Nail diseases are rarely given significant importance in general consultation and their specific examination is often neglected, while localization to the nails could be an initial sign of a syndrome or a systemic disorder. Although rarely, nail alterations could be a sign of a systemic disorder, in which a prompt observation is crucial for an early diagnosis. We describe the case of an elderly woman with a long history of nail dystrophy, previously labelled as nail fragility. Read More
