Unlabelled: CKD patients present deficient elimination of potassium. Ambulatory treatment with hypotensors, mainly angiotensin-renin system inhibitors, can be associated in these patients with potassium retention and risk of hyperkalemia. In pre-dialysis stage-5 CKD patients, the use of medication accompanied by hyperkalemia increases risks of developing it. Using diuretics like spironolactone also increases this risk. Serum potassium can also increase in case of inappropriate consumption of potassium-rich food (bananas). Since ambulatory care does not always rigorously control hyperkalemia in CKD patients we consider it is useful to screen patients when they are referred to dialysis services. The screening can reflect the management of ambulatory CKD patients under treatment with ACE-I and ARB hypotensors. We remark that beta-blockers are attributed a (limited) role in increasing the values of serum K., Material and Method: We studied a group of 477 stage-5 CKD patients referred for dialysis to The Dialysis Centre of the Emergency County Hospital Timişoara. The average age of the patients was 57.41 +/- 14.26 years. 260 were males and 217 females. All were stage-5 CKD with GFR < 15 mL/min/1.73 m2, with a group average value of eGFR of 5.72 +/- 2.81 mL/min/1.73m2. Our investigations showed hypokalemia in 14 patients (2.93%). Hyperkalemia was found in 179 patients. Of these, 124 had mild hyperkalemia (5.5-6.4 mEq/L), 45 patients had medium hyperkalemia (6.5-7.5 mEq/L) and 10 (2.09%) had severe hyperkalemia (K > 7.5 mEq/L)., Discussion: Hyperkalemia was more frequent in patients who had been treated with blockers of the renin-angiotensin system than in patients who had used other hypotensors or who had not needed hypotensors and had not taken diuretics. Severe hyperkalemia (K > 7.5 mEq/L) was present both in patients treated with blockers of the renin-angiotensin system and in those treated with other hypotensors and in 1 case without hypotensor or diuretic treatment. 2 cases treated with blockers of the renin-angiotensin-aldosterone system with severe hyperpotassemia associated antialdosteronic diuretics, cumulating hyperpotassemic effects. Diuretic treatments with loop diuretics influenced the values of serum K of most patients. Hyperkalemia represents an important problem in nephrology because of the risks it induces in the treatment ofpre-dialysis CKD patients and it requires attentive monitoring.

Background: It is known that secondary hyperparathyroidism (SH) and particularly skeletal changes is a severe condition in chronic kidney disease (CKD). Sagliker syndrome (SS) is a very prominent feature in CKD including uglifying human face appearances, short stature, extremely severe maxillary and mandibulary changes, soft tissues in the mouth, teeth-dental abnormalities, finger tip changes and severe psychological problems., Methods: In the last 8 years we have confronted 36 extremely incredible SS cases in CKD by performing an international study in Turkey, India, Malaysia, Romania and Egypt., Results: In addition to the uglifying human face appearance, we found extremely severe X-ray and tomographical, pantomographical, histo-pathological changes in the head and whole body. Finally, we compared previous face pictures with recent ones. Just a few years earlier they had been pretty and good-looking young boys and girls. By investigating their history, we understood they had not received proper therapy and were in the late-irreversible period., Conclusion: SS is a serious and severe complication of CKD. Late and improper treatment leads to abnormalities throughout skeleton particularly in the skull and face. Changes particularly in children and teens become irreversible-disastrous for appearance and psychological health. Appropriate treatment must begin as early as possible in specialized centers. It is possible that SS patients may survive long-term with dialysis, but with all those particular changes could anyone claim this type of life would continue in an acceptable way without extending their height, correcting all the changes in the skull and face, remodeling new faces and most particularly convincing the patients to deal with all those tragi-dramatic psychological problems?

Unlabelled: INTRODUCTION. This report describes the current status of nephrology and renal replacement therapy (RRT) in Romania, a country with previously limited facilities, highlighting national changes in the European context., Methods: Trends in RRT development were analysed in 2003, on a national basis, using the same questionnaires as in previous surveys (1991, 1995). Survival data and prognostic risk factors were calculated retrospectively from a large representative sample of 2284 patients starting RRT between January 1, 1995 and December 31, 2001 (44% of the total RRT population investigated)., Results: In 2003, RRT incidence [128 per million population (p.m.p.)] and prevalence (250 p.m.p.) were six and five times higher, respectively, than in 1995. The annual rate of increase in the stock of RRT patients (11%) was supported mainly by an exponential development of the continuous ambulatory peritoneal dialysis (CAPD) population (+600%), while the haemodialysis (HD) growth rate was stable (+33%) and renal transplantation made a marginal contribution. Renal care infrastructure followed the same trend: nephrology departments (+100%) and nephrologists (+205%). The characteristics of RRT incident patients changed accordingly to current European epidemiology (increasing age and prevalence of diabetes and nephroangiosclerosis). The estimated overall survival of RRT patients in Romania was 90.6% at 1 year [confidence interval (CI) 89.4-91.8] and 62.2% at 5 years (CI 59.4-65.0). Patients' survival was negatively influenced (Cox regression analysis) by age >65 years (P < 0.001), lack of pre-dialysis monitoring by a nephrologist [P = 0.01, hazards ratio (HR) = 0.8], severe anaemia, lack of erythropoetin treatment (P < 0.001, HR = 0.6), and co-morbidity, e.g. cardiovascular diseases (P < 0.001, HR = 1.8) and diabetes mellitus (P < 0.001, HR = 2.2)., Conclusions: Although the rate of increase in RRT patient stock in 1996-2003 in Romania was the highest in Europe, the prevalence remained below the European mean. As CAPD had the greatest expansion, followed by HD, an effective transplantation programme must be set up to overcome the imbalance. The quality of RRT appears to be good and survival was similar to that in other registries. Further evolution implies strategies of prevention, based on national surveys, supported by the Romanian Renal Registry.

This retrospective study was performed on 92 patients diagnosed with acute renal failure (ARF) post discontinuous rifampicin treatment, admitted between 1974-2000, in Hemodialysis Center of 1st Timisoara Clinical County Hospital. The passage from the continuous treatment (7/7) to discontinuous RMP treatment triggered the ARF in 77 patients and the restart of the treatment after one year or more of treatment arrest, lead to ARF in 15 cases. The ARF symptomatology appeared in the first 12 hrs of treatment resumption in 14.13% cases and in 85.87% after 38.5 +/- 8.2 hrs. The most frequent symptoms were lumbar pain in 76.08%, nausea and vomiting in 60.86%, abdominal pain (52.17% of cases) flu-like (fever, chills, myalgia), jaundice, diarrhea, hypotension, confusion and hypertension in only 7.6% of cases. In 94.56% of cases renal symptoms appeared in normal kidneys. The renal injury evolution was favorable, with significant improvements after 20 days in serum and urine biological parameters. The antibodies anti-RMP were present in serum 55.43% of patients, in 80.39% of them, the presence of antibodies was related to high values of gamma-globulins. In 33.69% of patients sterile leukocyturia, considered a marker of interstitial nephritis, was present. The most frequent associated ARF complications were the hemolytic anemia emphasized by high levels of unconjugated bilirubin and positive Coombs' test in 93.3% of patients, and liver injuries, present in 41.69% of cases. Thrombocytopenia was registered in 27.7% of cases, infections in 28.6%, gastrointestinal complications in 11.95%, and cardiovascular complications in 9.78% of cases, these severe forms leading to the death of patients. The ARF post discontinuous rifampicin treatment presents a favorable evolution even when it is associated with other organ or systems complications. The ARF and associated complications are due to the specific immune system activation by rifampicin, and by direct toxic effects of rifampicin at tissues level.
