The relationship between serum albumin levels and 24-h ambulatory blood pressure monitoring recordings in non-diabetic essential hypertensive patients
OBJECTIVES: The goal of this study was to evaluate the relationship between serum albumin levels and 24-hour ambulatory blood pressure monitoring (24-h ABPM) recordings in non-diabetic essential hypertensive patients. METHODS: A total of 354 patients (mean [SD] age: 55.5 [14.3] years, 50% females) with essential hypertension and 24-h ABPM recordings were included. Patient 24-h nighttime and daytime ABPM values, systolic and diastolic dipping status and average nocturnal dipping were recorded. The correlations between serum albumin levels and nocturnal systolic and diastolic dipping were evaluated, and correlates of average nocturnal systolic dipping were determined via a linear regression model. RESULTS: Overall, 73.2% of patients were determined to be non-dippers. The mean (SD) levels of serum albumin (4.2 [0.3] g/dL vs. 4.4 [0.4] g/dL,
Clinical outcomes and mortality in elderly peritoneal dialysis patients
OBJECTIVES: To evaluate the clinical outcomes and identify the predictors of mortality in elderly patients undergoing peritoneal dialysis. METHODS: We conducted a retrospective study including all incident peritoneal dialysis cases in patients ≥65 years of age treated from 2001 to 2014. Demographic and clinical data on the initiation of peritoneal dialysis and the clinical events during the study period were collected. Infectious complications were recorded. Overall and technique survival rates were analyzed. RESULTS: Fifty-eight patients who began peritoneal dialysis during the study period were considered for analysis, and 50 of these patients were included in the final analysis. Peritoneal dialysis exchanges were performed by another person for 65% of the patients, whereas 79.9% of patients preferred to perform the peritoneal dialysis themselves. Peritonitis and catheter exit site/tunnel infection incidences were 20.4±16.3 and 24.6±17.4 patient-months, respectively. During the follow-up period, 40 patients were withdrawn from peritoneal dialysis. Causes of death included peritonitis and/or sepsis (50%) and cardiovascular events (30%). The mean patient survival time was 38.9±4.3 months, and the survival rates were 78.8%, 66.8%, 50.9% and 19.5% at 1, 2, 3 and 4 years after peritoneal dialysis initiation, respectively. Advanced age, the presence of additional diseases, increased episodes of peritonitis, the use of continuous ambulatory peritoneal dialysis, and low albumin levels and daily urine volumes
Ertapenem-induced acute reversible peripheral neuropathy in chronic kidney disease: 3 case reports
Sahutoglu, Tuncay/0000-0003-2015-4421; Yildirim Disli, Safak/0000-0002-5869-0679WOS: 000369249900006PubMed: 26558370Background: Ertapenem is a broad-spectrum and long-acting carbapenem which is predominantly eliminated by the kidneys, and it requires dose adjustment in renal failure. Although it is known that excessive doses of ertapenem can cause neurotoxicity, there are very few case reports of ertapenem-induced reversible peripheral neuropathy in the literature when used with renal adjusted doses. Study design and methods: We report 3 patients with a history of stage 4 or 5 chronic kidney disease (CKD) who developed acute reversible peripheral neuropathy proven with electroencephalography (EEG) and electromyography (EMG). All patients received renal adjusted doses of ertapenem for complicated urinary tract infection (UTI). We also discuss the incidence of carbapenem-related neurotoxicity, mechanisms, and risk factors with a review of the literature. Results: All patients developed acute peripheral, and additionally one acute central nervous system, neuropathy within 1 week of treatment with ertapenem, which was confirmed by EMG. Complete clinical recovery was obtained in all patients within 2 weeks of cessation of ertapenem treatment, and electromyography was confirmatory in all patients. Conclusion: Ertapenem is potentially neurotoxic in patients with CKD even when it is given with renal adjusted doses according to recommendations. Although carbapenem-related neurotoxicity most commonly manifests as seizures, our series indicates that acute and reversible peripheral neuropathy can also develop. Clinicians administering ertapenem for patients with a GFR of < 30 mL/min/1.73 m(2) should be cautious
Persistent left superior vena cava: Two case reports and a review from nephrologists' perspective
Sahutoglu, Tuncay/0000-0003-2015-4421; sevinc, mustafa/0000-0003-2804-4884; Hasbal, Nuri Baris/0000-0002-2229-5140WOS: 000379825800009PubMed: 26843030Thoracic venous anomalies without congenital heart anomalies are present in minority of the population, but they are frequent enough to be encountered while placing hemodialysis catheters through the jugular or subclavian veins. Persistent left superior vena cava is the most commonly seen anomaly and it is rarely noticed before the observation of an unusual course of hemodialysis catheter or guidewire on chest X-ray. We present two patients with previously unspotted persistent left superior vena cava and uncomplicated hemodialysis catheter insertions through the internal jugular veins with good catheter functions. Review of the relevant literature from a nephrologists' perspective with technical aspects is provided
Acute severe hepatitis and hemophagocytosis in adult onset Still’s disease
We report a 44-year-old male Turkish patient with adult onset Still's disease (AOSD) complicated by acute severe hepatitis and hemophagocytosis. Initial investigations for fever and rapidly progressive elevation of liver function tests were not diagnostic. Routine evaluations of liver and bone marrow biopsies missed the fundamental pathology. Extremely elevated ferritin levels led to a more detailed search, and immunohistochemical staining with CD68 for macrophages revealed extensive hemophagocytosis in both the first and second bone marrow biopsies, as well as in the liver biopsy. Treatment with steroid and cyclosporine A induced complete remission

Clinical course of abdominal aortic aneurysms in Behcet disease: a retrospective analysis
Arterial aneurysms are rare manifestations of Behcet Disease (BD) with high morbidity and mortality. This study aimed to investigate the clinical course of BD patients with abdominal aortic aneurysms (AAA). We retrospectively searched charts of BD patients, followed up between 1988 and 2011, to identify those with AAA with at least 6-month clinical and radiological follow-up data. Chart review revealed 12 patients (11 males) with AAA amongst 1224 patients; follow-up data from 11 patients were available. The most common symptoms were lower back and abdominal pain. The only pre-treatment complication was a spontaneous rupture. All but one patient received corticosteroid and cyclophosphamide pulses for the induction, and corticosteroid and azathioprine for the maintenance treatment; one patient received only the maintenance treatment. Two patients had surgical graft interposition, without postoperative complications. Seven patients had endovascular stenting; five of them (71.4%) showed radiological regression after 32.5(13.4-53.8)months, while four (57%) had clinical improvement after 11.8(0.2-29.4)months. However, one non-responsive patient developed stent infection and exsanguinated during percutaneous drainage, and one patient developed femoral artery pseudo-aneurysm at the catheter insertion site. Another patient developed a new aneurysm under the maintenance treatment. Medical treatment alone yielded radiological regression in one of two patients. Current immunosuppressive, surgical or endovascular approaches can provide clinical and radiological improvements lately in BD patients with AAA. Furthermore, complication rates seem to be high with interventional approaches. These findings suggest an unmet need for safer alternative treatments
The predictive value of malnutrition - inflammation score on 1-year mortality in Turkish maintenance hemodialysis patients
Sahutoglu, Tuncay/0000-0003-2015-4421; sevinc, mustafa/0000-0003-2804-4884WOS: 000384940700006PubMed: 27345184Objective: the aim of this study was to evaluate the predictive value of malnutrition-inflammation score (MIS) on short-term mortality and to identify the best cut-off point in the Turkish maintenance hemodialysis (MHD) population. Methods: A total of 100 patients on MHD were included in this prospective single-center study. Demographic, anthropometric, and biochemical data were obtained from all patients. the study population was followed up as a 12-month prospective cohort to evaluate mortality as the primary outcome. Results: Median (IQR) age and HD vintage of 100 patients (M/F: 52/48) were 53 (39.5 - 67) years and 53.5 (11 - 104.7) months, respectively. Deceased patients (n = 7) had significantly older age (years) (50 (38.5 - 63.5) vs. 70 (62 - 82), respectively, p = 0.001), lower spKt/V (1.60 (1.40 - 1.79) vs. 1.35 (0.90 - 1.50), respectively, p = 0.002), lower triceps skinfold thickness (14 (10 - 19) vs. 9 (7 - 11), respectively, p = 0.021) and higher MIS (5 (4 - 7) vs. 10 (7 - 11), respectively, p = 0.013). in the ROC analysis, we found that the optimal cut-off value of MIS for predicting death was 6.5 with 85.7% sensitivity and 62.4% specificity (positive and negative predictive values were 0.6951 and 0.8136, respectively). Advanced age, low spKt/V, and high MIS were found to be predictors of mortality in multivariate logistic regression analysis. the 1-year mortality rate was significantly higher in MIS > 6.5 group compared to the MIS 6.5 was found to be significantly lower (47.8 +/- 0.16 vs. 43.6 +/- 1.63 weeks, respectively, p (log-rank) = 0.012). Conclusion: MIS is a robust and independent predictor of short-term mortality in MHD patients. Patients with MIS > 6.5 had a significant risk, and additional risk factors associated with short-term mortality were advanced age and low spKt/V
