Glomerulonefritis membranosa merupakan lesi yang menyebar difus pada semua glomerulus karena terjadi penebalan membran basalis. Secara morfologis. Biopsia renal que demuestre glomerulonefritis mesangial clase IIb, . Los pacientes con glomérulonefritis proliferativa o membranosa (Clase III, IV y V de la . We recommend that initial therapy be started ONLY in patients with nephrotic syndrome AND when at least ONE of the following conditions are met.
He developed end-stage renal failure at the age of 6 years and received a renal allograft from an unrelated living donor. Four years later, he was hospitalized again with an abdominal mass.
Burkitt's lymphoma was diagnosed and he was put on chemotherapy. However, unfortunately, he died because of cancer progression 7 months later. Genetic studies on DNA samples of the patient and his parents were performed to analyze the NPHS1 gene for suspected congenital nephrotic syndrome, Finnish type.
PCR amplicons were purified and subjected to direct sequencing using an automated capillary sequencer. Sequences were compared to the reference sequences deposited in the public database NCBI.
In the patient, homozygosity for a 1 bp duplication near the splice acceptor site of exon 17 of the NPHS1 gene was detected intron c. In both parents the heterozygous carrier status for the mutation was confirmed Figure 2.
This variation has not been described as a mutation or polymorphism, so far. It is predicted to abrogate splice acceptor function and lead to abnormal splicing of exon 17, thus indicating that this change is indeed a pathogenic mutation. These findings strongly confirmed the diagnosis of CNF in this patient.
Figure 2. Electropherograms showing the junction region of intron 16 and exon 17 the shadow, uppercase letters of the NPHS1 gene. The arrow marks the mutation. The NPHS1 gene covers 26 kb of genomic sequence, comprises 29 exons, and is located on chromosome 19q It encodes nephrin, a single pass transmembrane protein consisting of eight extracellular immunoglobulin-like modules, a fibronectin type III-like motif and a cytosolic C-terminal tail.
Nephrin represents an important structural and signaling protein in podocytes, that regulate ultrafiltration of proteins at the slit diaphragm and connects foot processes in a zipper-like fashion. To date, many other NPHS1 mutations have been reported in Finnish and non-Finnish populations, including deletions, insertions, nonsense, missense, splice site and promoter mutations.
Three serious adverse events occurred over 51 patient years. No patients died or progressed to ESKD. Conclusions Treatment of idiopathic membranous nephropathy with RCP resulted in high rates of complete remission.
Larger studies evaluating this regimen are warranted. Electronic supplementary material The online version of this article doi Keywords: Membranous nephropathy, Cyclophosphamide, Rituximab, Remission Background Membranous nephropathy MN is one of the most common causes of the nephrotic syndrome [ 1 ].
The course of idiopathic MN in patients not receiving immunosuppressive therapy is variable. When immunosuppressive therapy is indicated, current guidelines recommend the Ponticelli protocol, a 6-month course of alternating monthly oral cyclophosphamide and corticosteroids [ 6 , 7 ]. Alternatively, a calcineurin inhibitor-based regimen with or without low-dose prednisone is recommended if there is a desire to avoid an alkylating agent [ 6 ].
The M-type phospholipase A2 receptor PLA2R , a transmembrane protein expressed on glomerular podocytes, has been demonstrated to be the target antigen in most cases of idiopathic MN [ 11 ]. The median follow-up since the renal biopsy was 63 months range Bad prognostic factors were an elevated creatinine and high blood pressure at the moment of the biopsy.
Conclusions: The clinical outcome of these patients was bad. Twelve percent reached a stage of terminal renal failure. Este compromiso renal, en algunos casos, conduce a insuficiencia renal terminal IRT y es una de las causas principales de muerte. Las causas de muerte se agruparon en: lupus activo, complicaciones de la IRT, infecciones y otras.
