A rare case of hydatid cyst-associated AA amyloidosis and literature review of hydatid cyst-associated nephropathy

Abstract

Hydatid disease is an infective picture caused by echinococcus, which progresses with cysts in various organs, especially in the liver. Renal involvement is an unusual location in the course of the disease. Although mostly asymptomatic renal cysts are seen, rarely glomerular or tubular associated nephropathy develops. In addition, the development of amyloidosis has been shown previously in patients with untreated chronic hydatid cysts. We wanted to bring a 27-year-old female patient with a 10-year history of hydatid cyst and AA amyloidosis to the literature. In addition, in our literature review for hydatid disease-associated nephropathies, we brought together data from 12 studies involving a total of 21 cases. Of these cases, 3 were membranous glomerulonephritis (MGN), 5 were, membranoproliferative glomerulonephritis (MPGN), 1 was minimally change disease (MCD), 5 were AA amyloidosis (including our case), 3 were immunoglobulin A nephropathy (IgAN), 1 was tubulointerstitial nephritis (TIN), 1 was chronic kidney disease (CKD), 1 was TIN with mesangioproliferative glomerulonephritis (MesPGN), 1 was TIN with IgAN, 1 was MPGN with immunoglobulin M nephropathy (IgMN). In this way, we wanted to shed light on the relationship between Echinococcus and nephropathy. In this way, we wanted to emphasise the necessity of doing renal examinations in the follow-up of hydatid cyst patients.
