Due to the increase of organ shortage and still inadequate development of cadaver transplantation, many end-stage patients from the Balkan region travel mostly to India to buy a kidney. Despite all the ethical dilemmas and discussions, organ sales is present nowdays in Third-World countries. Sixteen patients (13 from Macedonia and 3 from Kosovo, SCG) were observed clinically during a period of 10 years. Recipients of mean age 36.5 years (range 10 to 58) displayed the following underlying diseases: chronic glomerulonephritis (n = 5), urethral valves with reflux (n = 2), ADPKD (n = 1), hypertensive nephropathy (n = 4), lithiasis (n = 1), and unknown cause of ESRD (n = 3). The donor population was young (22 to 29 years). Most patient records did not include data on HLA, cross-match, MLC, kind of surgery, or usual pretransplant workup. The immunosuppressive protocol included CyA, PRED, and AZA or MMF. All transplanted patients were followed on an outpatient basis in our department; patients with complications were hospitalized. The 1, 3, 5, and 10 year Kaplan Meier graft survival rates were 78.6%, 50.2%, 33.3%, and 18.8%, respectively. Seven patients were lost (43.7%), two during the first month after transplantation, two at the end of the first year, and three at 5, 6, and 8 years thereafter. The main reasons for death were severe pulmonary infections with sepsis, hepatitis B with liver cirrhosis, Kala Azar, CMV, and cancer of the colon. Five grafts were lost due to repeated rejection episodes and chronic graft nephropathy. The last three cases remained with good renal function and actual serum creatinine values of 135 +/- 9. In view of this experience, the authors cannot recommend this type of transplantation, not only from the ethical point of view, but also from frequent medical and surgical complications which are sometimes life threatening.

Endothelin (ET)-1 is a potent vasoconstrictor peptide with pro-inflammatory, mitogenic, and pro-fibrotic properties that is closely involved in both normal renal physiology and pathology. ET-1 exerts a wide variety of biological effects, including constriction of cortical and medullary vessels, mesangial cell contraction, stimulation of extracellular matrix production, and inhibition of sodium and water reabsorption along the collecting duct, effects that are primarily mediated in an autocrine/paracrine manner. Increasing evidence indicates that the ET system is involved in an array of renal disorders. These comprise chronic proteinuric states associated with progressive glomerular and tubulointerstitial fibrosis, including diabetic and hypertensive nephropathy, glomerulonephritis and others. In addition, ET-1 is causally linked to renal disorders characterized by increased renal vascular resistance, including acute ischaemic renal failure, calcineurin inhibitor toxicity, endotoxaemia, hepatorenal syndrome and others. Furthermore, derangement of the ET system may be involved in conditions associated with inappropriate sodium and water retention; for example, in congestive heart failure and hepatic cirrhosis. Both selective and non-selective ET receptor antagonist have been developed and tested in animal models with promising results. As key events in progressive renal injury like inflammation and fibrosis are mediated via both ET(A) and ET(B) receptors, while constrictor effects are primarily transduced by ET(A) receptors, dual ET receptor blockade may be superior over selective ET(A) antagonism. Several compounds have been developed with remarkable effects in several models of acute and progressive renal injury. Thus, clinical studies are required to assess whether these results can be confirmed in humans, hopefully leading to novel and effective therapeutic options with few side effects.

Hepatitis C virus (HCV) infection is often associated with kidney diseases such as membranoproliferative glomerulonephritis (MPGN), with and without cryoglobulinemia, membranous glomerulonephritis (MGN) or glomerulosclerosis (FSGN). The aim of our study was to determine the frequency of HCV with or without hypertransaminasemia in patients with chronic nephropathy in the predialytic phase. We tested 340 subjects with chronic renal insufficiency (CRI) from our hospital's nephrology outpatient clinic for anti-HCV antibodies. In positive subjects we tested for HCV RNA by PCR method, monitoring, for at least 4 months, common biohumoral parameters including transaminases (AST, ALT). Of the 340 subjects, 46 (13.5%) were positive for HCV RNA, and 8 of these (17%) showed constant alteration of transaminases. HBsAg was found in 8 of the total study population (2.3%), and none of these showed altered transaminases. Type II diabetes mellitus was found in 26% (12/46) of the HCV-RNA positive patients, and in only 12.5% (37/294) of the negative ones. The kidney diseases we found in the 46 HCV-RNA positive patients were: diabetic nephropathy in 11 (23.9%), MPGN in 7 (15.2%), MPGN + cryoglobulinemia in 2 (4.3%), interstitial nephropathy in 4 (8.7%), IgA mesangial GN in 3 (6.5%), hypertensive nephropathy in 2 (4.3%), focal and segmental GN in 1 (2.2%), urologic disease in 4 (8.7%), other (hematological, genetic, iatrogenic) in 3 (6.6%), unknown in 9 (19.6%). Our data show that the most frequent kidney diseases associated with HCV infection were diabetic related nephropathy and MPGN with and without cryoglobulinemia. HCV infection had a positive association with diabetes. It is interesting to note that in this study population the hepatitis C concomitant to kidney disease was unusually mild: only 4 of the 46 subjects (9%) showed clinical, biohumoral and ultrasound evidence of cirrhosis.
