Although antibody titers in Tx, CAPD and HD patients presented significant increases after vaccination, the proportions of patients with protective antibody titers were lower in comparison to control group. Tx, CAPD and HD patients should be vaccinated every year to be able avoid potential morbidity and mortality of the influenza infection. Trial of high dose vaccination protocols may be useful to increase the proportion of patients with protective antibody levels.
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.
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.
Primary failure, early thrombosis, and inadequate maturation are the main complications encountered in arteriovenous fistulas. Doppler ultrasonographic assessment of flow-mediated dilatation (FMD) is currently used for the early diagnosis of atherosclerosis. Clinical experience in the use of FMD for preoperative assessment of vasculature is rather limited; therefore, we sought to elucidate the relationship between preoperative FMD and primary failure of the fistula. Thirty-three patients with end-stage renal disease who were admitted to our hospital between January and July 2005 were included in our study. Medical histories were established and the internal diameter, wall thickness, peak systolic flow rate, and resistive index (RI) were measured in the cephalic vein and radial and brachial arteries. Flow-mediated dilatation and nitrate-mediated dilatation (NMD) of the brachial artery were assessed. Fistulas were evaluated 48 hours and 30 days postoperatively. Brachial arterial internal diameter was lower in all fistulas that developed primary failure in 48 hours (0.4 ± 0.07 cm vs. 0.35 ± 0.07 cm, P = 0.016). The radial artery RI was found to be significantly elevated in fistulas with both early (48-hour) and late-term (30-day) failure (0.9 ± 0.08 vs. 0.68 ± 0.3, P = 0.01, and 0.86 ± 0.8 vs. 0.67 ± 0.3, P = 0.038, respectively). The brachial artery peak systolic flow rate was significantly reduced in patients in the radiocephalic fistula group that developed early and late-term failure (42.9 ± 12 cm/sec vs. 68.4 ± 10 cm/sec, P = 0.01, and 44.1 ± 13 cm/sec vs. 57.7 ± 16 cm/sec, P = 0.038, respectively). Our study, constrained by a smaller, older patient group, was unable to show a statistically significant correlation between FMD, NMD, and fistula success. Any single parameter may not be sufficient to assess vascular health preoperatively. A multifactorial approach incorporating parameters evaluating arterial and venous function might be more effective in predicting fistula success. Further studies on larger patient groups may indeed demonstrate the value of these assessments.
In the present study, it was observed that I.V administered iron in 20 and 100 mg doses did not cause additional deteriorating effect on oxidant stress and EDEF was even improved by I.V iron.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
