Rapidly progressive renal failure to reveal LCAT deficiency in an Algerian family.

Lecithin-cholesterol acyltransferase (LCAT) deficiency is an autosomal recessive disorder that can reveal two different diseases: a very interesting nephrological picture of complete enzyme deficiency characterized by the association of dyslipidemia, corneal opacities, anemia, and progressive nephropathy; and a partial form (fish-eye disease) with dyslipidemia and progressive corneal opacities only. We report herein the case of a 35-year-old man who presented hypertension, renal symptomatology of rapidly progressive glomerulonephritis associates: nephrotic proteinuria, severe renal failure, in combination with annular corneal opacities, anemia, and dyslipidemia. The diagnosis of familial LCAT deficiency was confirmed by clinical examination, characteristic dyslipidemia, undetectable LCAT levels in plasma, and positive family history.

Acute Cellular Rejection in A Kidney Transplant Recipient Following Vaccination with Inactivated SARS-CoV-2 Vaccine.

SARS-CoV-2 vaccines are being administered worldwide. Most of the reported side effects are mild and self-limiting with few reported cases of severe adverse reactions. Here we report a case of acute cellular rejection in a kidney transplant recipient following vaccination with an inactivated SARS-CoV-2 vaccine. fifty- one years old man with autosomal dominant polycystic kidney disease, who had received a kidney transplantation from a living related donor, 3 years ago, presented with an impaired kidney function seven days after receiving the first dose of Sinovac's COVID-19 vaccine. Kidney transplant biopsy revealed acute cellular rejection. The allograft function completely recovered after treatment with steroids. The analysis and investigation of the complications and adverse reactions induced by anti-COVID-19 vaccines, could increase our understanding of the underlying pathogenesis.  DOI: 10.52547/ijkd.6915.

[Leukocytoclastic vasculitis and acute renal failure following inactivated SARS-CoV-2 vaccine]. / Vascularite leucocytoclasique et néphrite interstitielle aiguë après vaccin à SARS-CoV-2 inactivé.

SARS-CoV-2 vaccines are being administered worldwide. Most side effects are mild and self-limiting with few reported cases of severe reactions. We report a case of leukocytoclastic vasculitis with acute kidney failure following aninactivated SARS-CoV-2 vaccine, unique for its dramatic visual presentation and its rapid response to treatment. This is the case of a 58years-old man presenting with fever, arthralgias and vascular purpura on his limbs associated with acute kidney failure requiring hemodialysis nine days after anti-COVID-19 vaccination. Skin biopsy revealed a leukocytoclastic vasculitis and a renal biopsy showed an acute tubulointerstitial nephritis. The vascular purpura resolved 7days after initiating treatment with prednisone but the patient remains in chronic renal failure. The analysis and investigation of the complications and adverse events induced by anti-COVID-19 vaccines could increase our understanding of the underlying pathogenesis.
