          Abstract

          Background/Aim: Aneurysms are known manifestations of autosomal dominant polycystic kidney disease (ADPKD). We investigated whether the dimensions of arteriovenous fistulas created for performance of haemodialysis were affected by the original disease. Methods: The lumen diameter of the fistula was studied by ultrasound in 19 patients with ADPKD and in 19 control patients. The patients’ sex, age, the duration of their fistulas, haemoglobin values and blood pressure levels were similar in both groups. The monitoring was performed along the forearm part of the vein, and the maximal diameter was measured. The diameters at the two needle insertion sites were also measured. Results: The ADPKD patients had a significantly higher fistula diameter than the control patients: 12 (range 8–19) mm versus 8 (range 6–24) mm at the widest level (p = 0.003). There were no significant differences in the diameters at the needle insertion sites. Conclusion: The receiving veins of arteriovenous fistulas in patients with ADPKD have an abnormality that causes a greater than normal dilatation in response to the arterialization. We postulate that this phenomenon is linked with the increased prevalence of aneurysms in ADPKD.

            Cellular localization and tissue distribution of polycystin-1.

             L Spruit,  J. Bruijn,  E Heer (1999)
            Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the formation of fluid-filled cysts in both kidneys, in addition to a variety of extra-renal manifestations. The PKD1 gene product, polycystin-1, encodes a novel protein with a putative role in cell-cell/cell-matrix interactions. The present study we focused on the (sub)cellular localization of polycystin-1 in cultured cells, and on its tissue distribution in various organs. In Madin Darby canine kidney (MDCK) cells, several polyclonal antibodies showed intense staining at the sites of interaction between adjacent cells, which remained after Triton extraction. Weak cytoplasmic staining was observed. No signal was detected at the free borders of cell aggregates, supporting a role for polycystin-1 in cell-cell interactions. At the tissue level, polycystin-1 expression was observed in specific cell types in tissues with known manifestations of the disease, but also in tissues of organs which have not been reported to be affected in ADPKD. Expression was frequently seen in epithelia, but also in endocrine cells (pancreatic islets, parathyroid-producing cells, clusters in the adenohypophysis, clusters in the adrenal gland, and Leydig cells in the testis). In addition, expression was observed in myocardium and more weakly in myocytes of cardiac valves, of the cerebral arteries, and of skeletal muscles. Copyright 1999 John Wiley & Sons, Ltd.
