In this study we determine the sexual problems and the prevalence of erectile dysfunction (ED) in male hemodialysis patients by means of the International Index of Erectile Function (IIEF). A total of 187 male patients were included in the study. All of the patients who underwent hemodialysis were asked to complete the IIEF questionnaire. The IIEF domain scores were calculated and erectile dysfunction grading was determined on erectile function domain. Patients were also asked to report whether they had disclosed their sexual problems to physicians or not.The mean age was 49.3 AE 13.2 y and the duration of hemodialysis was 38.1 AE 8.4 months. By means of the IIEF, the prevalence of erectile dysfunction of any degree was 80.7%. The prevalence of any ED for the patients < 50 y and ! 50 y was 74.5% and 86.6%, respectively. The prevalence and the severity of ED was significantly higher in patients ! 50 y. The frequency of intercourse attempts during the last four weeks was 1 -2 in 130 (69.5%) of patients. Only 1% of patients disclosed their erectile problems and sought medical assistance prior to our study.Erectile dysfunction is highly prevalent in hemodialysis patients. The prevalence and the severity of ED increased with age. Evaluations for ED should be included in routine assessment of hemodialysis patients.
Glomerular C4d deposition was found to be associated with more unfavorable histopathological and clinical findings at the time of diagnosis. Association of mesangial IgM deposition with the activation of lectin pathway is a novel finding. Mesangial IgM deposition in our patients may reflect the genetic heterology of IgAN between diverse populations. However, since these data are about association, a cause-and-effect about IgM and IgAN cannot be proven solely with these findings.
Objective To assess the efficacy of sildenafil for erectile dysfunction (ED) in patients on haemodialysis (HD) or peritoneal dialysis (PD), as men with end-stage renal disease (ESRD) often have sexual dysfunction (up to 82% among those on chronic dialysis). Patients and methods Forty-one patients with ED and in ESRD participated in an open-label prospective study. Thirty patients on HD and 11 on PD were asked to complete the International Index of Erectile Function (IIEF) and Fugl-Meyer life-satisfaction scale before and after sildenafil treatment. A total score in the erectile function domain of ≤ 25 was accepted as indicating ED. All patients were started on a 25-mg dose, which was increased to 50 mg if there was no response after two trials. In addition, the overall efficacy question was used to evaluate satisfaction, and patients reported any side-effects during treatment. Results The erectile function and intercourse satisfaction domains improved significantly in both groups ( P < 0.01). After sildenafil treatment, two-thirds of those on HD (20/30) and nine of the 11 on PD recovered their erectile function. The pretreatment scores on the IIEF and four domains (except sexual desire) of those responding were significantly higher than in those not responding ( P < 0.05). The satisfaction rate on the overall efficacy question was 80% and 82% for the HD and PD groups, respectively. At least one sideeffect was seen in 17 patients (43%); one had severe hypotension in the PD group. Overall, mild headache (seven patients, 18%) and flushing (12, 30%) were reported most often. Conclusions Sildenafil is a safe and satisfactory drug for improving erectile function in patients with ESRD.Patients were satisfied whether treated by HD or PD. Pretreatment scores on the IIEF may be useful for predicting the success of treatment.
Background: Renal transplant recipients should be considered at high risk for development of Mycobacterium tuberculosis infection (tuberculosis, TB). TB is relatively more frequent among transplant recipients than general population, depending on its epidemicity in the geographic region. Clinical manifestations in this group of patients may be atypical and deserve aggressive investigations for diagnosis. Tuberculin skin test has several limitations regarding diagnosis in chronic renal failure patients. In this retrospective study, we aimed to explore the prevalence and clinical manifestations of TB in renal transplant patients. Materials and methods: We retrospectively analyzed the data for TB prevalence, clinical presentations, and patient and graft survivals of total 320 pediatric and adult renal transplant recipients in our center between 1992 and 2010. Results: The prevalence of TB was 2.8%. Five patients received kidney from living-donor related and four from cadaveric donors. Cadaveric-donor patients received antithymocyte globulin for induction, and four patients received pulse steroid for acute rejection. The median duration of time between transplantation and TB was 21 (1-150) months, and between induction/pulse therapy and infection was 5 (1-100) months. The immunosuppressive protocols included prednisolone and cyclosporine/rapamycin with or without mycophenolate mofetil/azathioprine. The major symptoms were fever (77%), cough (66%), and abdominal pain (22%). Extrapulmonary TB with intestinal (2/9), pericardial (1/9), lymph node (1/9), and cerebral (1/9) involvements developed in five patients. One patient had both pulmonary and testicular involvements. All patients received quartet of anti-TB therapy for a median duration of 9 months. One patient died at the second month of therapy because of dissemination of TB, and one patient returned to hemodialysis because of chronic allograft nephropathy. Conclusion: The prevalence of TB was 2.8% in our renal transplant patients. The quartet of anti-TB treatment including rifampicin resulted in success in a majority of patients.
Aim: Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease. It accounts for 5–10% of patients with end-stage renal disease (ESRD). The aim of this multicenter study was to investigate the demographic and clinical characteristics of patients with ADPKD. Methods: 1,139 patients with ADPKD who were followed up at 12 different centers were recruited for this study. The investigated demographic and clinical characteristics were gender, age, smoking history, educational status, the existence of hypertension, hematuria, urinary tract infection, urinary tract stones and renal replacement therapy. Patients were considered as hypertensive if they were taking antihypertensive medications or if they had blood pressure (BP) of 140/90 mm Hg or greater. If the patients were currently on antihypertensive drugs, the classes of these agents were noted. Results: 548 male and 591 female patients were included and the mean age at initial diagnosis was 37.1 ± 16.3 years. 20.3% were current smokers whereas 15% were ex-smokers. The mean systolic and diastolic BPs were 136.1 ± 29.8 and 84.9 ± 17.8 mm Hg, respectively. 63.7% used antihypertensive drugs and 73.1% of those used renin-angiotensin system blockers. 11.8% had ESRD, of which 75.8% were treated with hemodialysis. Conclusion: This study showed that hypertension is the most common (72.6%) clinical finding in ADPKD patients in Turkey and renin-angiotensin system blockers are widely used.
In anaemia of chronic renal failure, the most important factor in the shortened erythrocyte survival may be lipid peroxidation of the cell membrane. Defective antioxidant activity may increase this damage. Although recombinant human erythropoietin (r-HuEPO) can effectively correct anaemia in chronic haemodialysis patients, its actions on lipid peroxidation and antioxidant activity are not clear. These actions were investigated in 13 patients undergoing chronic haemodialysis. Antioxidant activity, including red blood cell superoxide dismutase and total glutathione peroxidase levels and the lipid peroxidation product malondialdehyde, were measured before and 3 months after initiation of r-HuEPO treatment, using heparinized venous whole blood for cell and plasma determinations. Age-matched healthy volunteers were controls. Significantly higher levels of superoxide dismutase and total glutathione peroxidase were found in the patients than in the controls (p < 0.01). Plasma malondialdehyde levels were not affected by r-HuEPO. The results are explained by erythropoiesis and cellular haemoglobin synthesis due to r-HuEPO, followed by increase of circulating young red cells. The membranes of these young cells contain more antioxidant enzymes than the others. Despite r-HuEPO treatment, plasma malondialdehyde levels in haemodialysis patients may be higher than normal because of the uraemic milieu and the chronic haemodialysis.
Behçet's disease is a chronic multisystem vasculitis of unknown aetiology. This case report describes a patient who applied to the hospital because of dyspnoea, ascites, oedema of lower extremities and recurrent episodes of haemoptysis. For the last 12 yr, he had superior vena cava syndrome (SVCS) and cardiac and pulmonary involvement of Behçet's disease, and biochemical examination of ascite fluid yielded a chylous effusion containing triglyceride 421 mg dl-1 and cholesterol 49 mg dl-1. Chyloptysis was also detected by Sudan III stain. The patient died from cardiac tamponade in spite of cardiac fenestration. To the authors' knowledge, this is the first reported case of Behçet's disease with chylous ascites and chyloptysis in the English literature.
A patient with end-stage renal disease presented with reflex sympathetic dystrophy syndrome (RSDS) on her left hand 1 month after arteriovenous fistula (AVF) surgery. Magnetic resonance angiography revealed steal syndrome at the AVF level. Bone scintigraphy revealed early-stage RSDS. We considered that arterial insufficiency because of steal phenomenon following AVF surgery and underlying occlusive arterial disease triggered RSDS development.
