Pneumonia after kidney transplant: Incidence, risk factors, and mortality

Objectives: Pneumonia is an important cause of morbidity and mortality in recipients of solid-organ transplant. We aimed to determine risk factors for development of pneumonia and associated deaths in kidney transplant recipients. Materials and Methods: A retrospective review of medical records was performed for all kidney transplant recipients from December 1988, to April 2011. The diagnosis of community-acquired pneumonia was made from symptoms, clinical findings, and chest radiography. The diagnosis of nosocomial pneumonia was made according to published criteria. Laboratory and serologic tests, radiographic findings, cultures of respiratory specimens, and tissue biopsies were reviewed. Results: In 406 kidney transplant recipients, there were 82 patients (20%) who had 111 episodes of pneumonia, including 49 nosocomial episodes of pneumonia (44%). Bacterial infections were the most common cause (34 episodes [31%]). In multivariate analysis, significant risk factors associated with pneumonia episodes were older age, hypertension, cardiac disease, history of acute graft rejection, and not using everolimus/mycophenolate mofetil/prednisolone protocol. There were 28 episodes that resulted in death (25%), including 20 nosocomial episodes (71%). In multivariate analysis, significant risk factors associated with death from pneumonia episodes were antibiotic use in the previous 3 months, high C-reactive protein, and low albumin. Cutoff values for increased risk of death from pneumonia included C-reactive protein > 10 mg/dL and procalcitonin > 8.8 ng/mL. Conclusions: Recipients of kidney transplant may be at risk for pneumonia and associated death. Nosocomial pulmonary infections may be associated with marked morbidity and mortality in kidney transplant recipients

Analysis of liver function test abnormalities in kidney transplant recipients: 7 year experience

Objective: Immunosuppressive drugs, antimicrobial agents and infectious complications may cause liver function test abnormalities (LFTA) in kidney transplant recipients (KTR). The objectives of this study were to identify the outcome of (LFTA). To identify the risk factors affecting development and severity of hepatotoxicity in KTR. Methods: We retrospectively evaluated the medical records of KTR. Hepatotoxicity attacks were defined as impairment in liver function tests that was responsive to drug dose reduction or discontinuation, or treatment of specific causes such as infectious complications. Results: One hundred-fifty-six episodes of hepatotoxicity occurred in 107 patients in 281 KTR, with an incidence of 38%. Patients with hepatotoxicity episodes had a high total mortality rate, higher incidence of positive pre-transplant cytomegalovirus (CMV) IgM test, higher creatinine values during the first month post-transplant, underwent additional acute rejection episodes, and received fewer cyclosporin A based ID. Only positive CMV IgM testing was identified as a significant independent risk factor for hepatotoxicity in our multiple analysis. Mycophenolatemofetil (MMF) related hepatotoxicity was the most common cause of drug related LFTA. Conclusions: Patients with LFTA can have significant complications. Pre-transplant positive CMV IgM tests predispose transplant recipients to the development of LFTA during the post-transplant period. MMF can be a serious hepatotoxic drug

Does Serum R-Spondin-1 Play a Role in PCOS Pathophysiology?

Objective: Many new inflammatory and metabolic markers are considered to be involved in etiology of Polycystic ovary syndrome (PCOS). R-spondin-1 (Rspo1) is a member of the roof plate-specific spondin protein family. Rspo1 levels have been associated with obesity and insulin resistance. We aimed to investigate whether Rspo1 has a role in the pathophysiology of PCOS. Materials and Methods: This cross-sectional study was planned with newly diagnosed and untreated PCOS cases and a control group without PCOS. Patients with PCOS and healty participants were compared for Rspo1 levels. In addition, the PCOS group was also grouped according to body mass index (BMI) and Ferriman Gallwey scores (FGS) and compared in terms of Rsop1 levels. Results: A total of 47 patients in the PCOS group and 36 participants in the control group, as total 83 participants were included in the study. PCOS and control groups had similar age and BMI. As compared to the control group, PCOS patients had significantly higher FGS, homeostasis model assessment of insulin resistance scores, Rspo1, and total testosterone levels (

Effects of balance-coordination, strengthening, and aerobic exercises to prevent falls in postmenopausal patients with osteoporosis: A 6-month randomized parallel prospective study

Osteoporosis is a systemic disease characterized by the increase of bone fragility and fracture risk. Postmenopausal female osteoporotic patients were randomized into three groups: balance and coordination, strengthening, and aerobic exercise. The exercise programs were performed for 12 weeks, 1 hr each day for 3 days of the week. Patients were followed-up for 12 weeks after the initial intervention. After the exercise program, patients continued their daily life activities and were called back to the clinic for additional testing after 12 weeks. Static and dynamic balance measurements and pain and life quality assessments were performed at enrollment, and at the 12th and 24th weeks. Significant improvements in both the Timed Up and Go test and Berg Balance Scale values at the 12th week were only observed in the balance-coordination group. There were statistically significant improvements in night and daytime pain visual analog scale scores at the 12th and 24th weeks in the strengthening exercise group. No patient experienced falling during the 24th week follow-up. The strengthening exercises were observed to be more effective in pain reduction, and balance and coordination exercises were found to be more effective in improvement of static and dynamic balance

Assessing the impact of insulin glargine and detemir treatment to serum total IGF1 levels in the insulin-naive type 2 diabetic patients

Aim: The mitogenic potential of analog insulins due to their different insulin-like growth factor-1 (IGF1) receptor affinity is a situation that causes concern related to cancer risk. We aimed to examine the changes in the serum IGF1 levels formed by insulin glargine and detemir in the insulin-naive type 2 diabetic patients. Methods: The serum total IGF1 levels of the 62 insulin-naive type 2 diabetic patients were studied before and after 12 weeks of the started treatment with basal insulin analogs. Twenty-two and twenty patients (Group I and II) using the single-dose and double-dose insulin detemir and twenty patients (Group III) using insulin glargine were evaluated. Results: In Group I and Group II, the average 8.5% and 0.1% increases and in the Group III, 6.5% decreases were determined in the IGF1 values. The IGF1 changes were significant in the men but not in the women. Conclusion: In our study, it was determined that the insulin glargine depressed the serum IGF1 levels much more when compared to the insulin detemir. This result can be evaluated as the in vivo reflection of the in vitro findings related to the fact that the IGF1 receptor affinity of the glargine is higher

Assessment of factors related to the understanding of education and knowledge of self-care among patients with diabetes mellitus: A cross-sectional prospective study

The prevalence of diabetes mellitus is rapidly increasing particularly in developing countries. The aim of this study was to assess the knowledge and self-care practices of diabetes patients and to assess the contribution of the education to this knowledge level and glycemic control. We formed patient groups consisting of 15-30 diabetic patients. First, patients were surveyed using a diabetes self-care knowledge questionnaire (DSCKQ-30). Sunsequently, a standard PowerPoint presentation about diabetes self-management was made to the patients who were then surveyed again using DSCKQ-30. All patients were invited to hospital to measure their control glycated hemoglobin (HbA1c) level 3 months later. Of the total 364 participants, 62.9% were females. Significant increases in the percentage of correct responses were determined in all components between, before and after education. There was a significant decline of 1.1 in HbA1c levels after 3 months of education. Married or active working patients had a better understanding of the education about diabetes and had a greater knowledge of self-care management regardless of their level of education or income. Education about diabetes can significantly improve knowledge of self-care management and can help in achieving glycemic control. Continuing education about self-care management and complications is crucial and this should be accompanied by a regular assessment of pateients' diabetic knowledge

The effect of hemodialysis, peritoneal dialysis and renal transplantation on nutritional status and serum micronutrient levels in patients with end-stage renal disease; Multicenter, 6-month period, longitudinal study

Purpose: Nutritional status and micronutrient levels of end stage renal disease (ESRD) patients may vary depending on the mode of renal replacement therapy (RRT). We aimed to compare the effects of hemodialysis, peritoneal dialysis (PD) and renal transplantation (RT) on micronutrient levels and nutritional status in ESRD patients. Patients and Methods: A total of 77 ESRD patients who had not received RRT were included in this prospective longitudinal study. All ESRD patients underwent a blood serum analysis that assessed the micronutrients such as selenium, copper, zinc, chromium, retinol, thiamine and vitamin B6 as well as a nutritional status assessment. After the baseline assessments and the initiation of RRT was accomplished, all patients were followed for 6 months. Results: The study showed significant improvements in subjective global assessment scores (percentage increases in score A were 26.6 and 36.6; p= 0.039 and p= 0.001; respectively), mid-arm circumference and the skin-fold thicknesses (p < 0.001, p < 0.001; respectively) in the RT and hemodialysis groups. The examinations at sixth month revealed a significant increase in body weight (4.8 kg; p= 0.002) and albumin levels (0.6 g/dL; p < 0.001) in only RT group. Zinc, thiamin and vitamin B6 were the most deficient micronutrients (44.1 %, 24.7 % and 35.1 %; respectively) in ESRD patients. There was a significant increase in selenium and retinol levels (p= 0.020 and p < 0.001; respectively) but a significant decrease in thiamin levels (p= 0.041) in RT patients. A significant increase in retinol levels (p= 0.028) and a significant decrease in thiamin levels (p= 0.022) was observed in the hemodialysis patients. However, no significant change in micronutrient levels was observed in the PD patients. Conclusion: The results support the recommendation that ESRD patients should be supplemented with watersoluble vitamins, especially thiamine and vitamin B6, and trace elements, especially zinc. RT appears to be superior to other modes of RRT when examining SGA score, anthropometric measurements, albumin and micronutrient levels
