Cytopenia in autosomal dominant polycystic kidney disease (ADPKD): merely an association or a disease-related feature with prognostic implications?

Tijdschriftbijdrage - Tijdschriftartikel

Autosomal dominant polycystic kidney disease (ADPKD) is associated with distinct cytopenias in observational studies; the most consistent and strongest association is seen with alternations in the lymphocytic lineages. Although the underlying mechanism of these associations is unclear, it has been hypothesized to be secondary to sequestration of white blood cells in cystic organs, or related to the uremic environment in chronic kidney disease (CKD). However, since mutations in PKD1 or -2 affect several immunomodulating pathways, cytopenia may well be an unrecognized extrarenal manifestation of ADPKD. Furthermore, many important questions on the clinical implications of this finding and the effect on the disease course in these patients are unanswered. In this review article, we provide an overview of the current evidence on cytopenia in ADPKD and explore the underlying mechanisms of this association and its potential prognostic implications. Based on the current literature, we hypothesize that polycystin deficiency can disturb immune cell homeostasis and that cytopenia is thus an intrinsic feature of ADPKD, related to genetic factors. Taken together, these findings warrant further investigation to establish the exact etiology and role of cytopenia in patients with ADPKD.
