Detailed Description
Systemic lupus erythrematosus (SLE) is an autoimmune disease with increasing prevalence and incidence , The clinical manifestation is multifaceted and targets the musculoskeletal system, the skin and different organs like lung and kidney From 30-80% of SLE patients develop lupus nephritis (LN) which often leads to chronic kidney disease (CKD) and end-stage renal disease (ESRD) and is associated with an overall poor prognosis and high mortality Diagnosis of LN is made by kidney biopsy, which still remains the gold standard Histological evaluation distinguish between different stages of LN upon morphological changes within the kidney .
However, noninvasive methods to diagnose and guide LN therapy are currently not established in the clinic.
On the other hand, an early diagnosis is important for the therapeutic success and thereby lowers the risk of ESRD In this context, classical clinical markers for renal dysfunction are insufficient for an early assessment of the need for renal biopsies and subsequently to decide about the optimal therapy.
Even though traditional biomarkers like antids DNA antibodies and complement deficiency are widely accepted as diagnostic instruments to assess disease activity, their specificity is rather low, and they appear to be more suitable to confirm diagnosis of SLE and LN in an already likely clinical setting Ceramides are a family of waxy lipid molecules ,composed of sphingosine and fatty acide ,found in high concentration with in the cell membrane of eukaryocyte cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer Ceramides and other sphingolipids found in cell membrane were purely supporting structural elements,also participate in variety of cellular signaling, regulating differentiation, proliferation, Programmed cell death(PCD) Sphingolipids are a heterogenous group of lipids with more than 400 single compounds formed by structural and chemical modifications of a sphingosine backbone Recent studies reveal that blood sphingolipids not only have important signaling properties but also serve as biomarkers in various renal disease Patyna etal in 2019 concluded that ceramides in blood could act as potent biomarker for renal impairment in patient
