Our aim was to determine the relationship between the modality of renal replacement therapy and inflammation markers, BP control, and quality of life (QoL). Sixteen hemodialysis, 17 peritoneal dialysis patients, and 27 kidney transplant receivers (KTr) have been included in this study. Short Form-36 (SF-36) for the evaluation of QoL and ambulatory BP monitoring were performed on the same day. Erythrocyte sedimentation rate, CRP, IL-6, and IL-10 were measured. While the mean IL-10, IL-6, and CRP levels were the highest in the dialysis groups, there were no significantly differences any parameters for all groups. QoL was better in the KTr almost as in healthy controls but worse in the dialysis patients. It should be taken into account that hypertension may occur at night even if the daytime BP is normal in KTr., (© 2021 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.)

To investigate the frequency and risk factors of ED in haemodialysis patients (HDps) and kidney transplantation (KTx) recipients (KTxRs). HDps and KTxRs between the ages of 18-65 were compared in terms of ED. IEFF-15 (International Index of Erectile Function) score was used to evaluation of ED. Fifty-seven male HDps and 52 male KTxRs with a mean age of 45.6 ± 10.4 years were included in our study. DM, CAD, hyperlipidaemia, smoking and beta blocker use were higher HDps (p = 0.037, p < 0.001, p = 0.001, p = 0.001 and p = 0.031 respectively). There was no ED in five (8.8%) HDps and 27(51.9%) KTxRx. Severity of ED was significantly higher in HDps (p < 0.001). In multiple logistic regression analysis, KTx was found the most relevant associated factor with ED. KTxRs had decreased risk for ED (OR = 0.09, 95% CI 0.02-0.30, p < 0.001). ED is significantly more common in HDps than KTxRs. Known risk factors for ED, HT, DM, CAD, HL, smoking, obesity and beta-blocker use were not related to ED in the HDps and KTxRs, and the KTx was positively effective for ED in patients undergoing renal replacement therapy., (© 2021 Wiley-VCH GmbH.)

Secondary hyperparathyroidism (SHPT) is a common problem in patients with end-stage renal disease. In cases with severe and resistant SHPT, surgical parathyroidectomy (PTX) is recommended. Hungry bone syndrome (HBS) following surgical PTX is most often associated with hypocalcemia and hypophosphatemia. The mechanisms for the HBS are not clear, and a method for its prevention has not been established. We present three hemodialysis patients with persistant hypophosphatemia after PTX. In our parathyroidectomized patients, hypocalcemia could be corrected with calcium and vitamin D treatment, but hypophosphatemia continued for eight months in one patient and in two other patients until the last visit (10 and 2 months, respectively). Predisposing factors such as old age, diabetes mellitus and parathyroid adenoma were not found in our patients. All three patients were younger (<35 years old) and anuric. Hemodialysis durations were seven, three and two years. In summary, HBS presented with hypocalcemia, and especially hypophosphatemia cannot be developed uncommonly and may persist for a long time following PTX in HD patients.

Objective: It is known that skeletal changes due to secondary hyperparathyroidism (SH) can be severe in chronic kidney disease (CKD). Recently described Sagliker syndrome (SS) is a very striking and prominent feature of SH in CKD, including an uglifying appearance to the face, short stature, extremely severe maxillary and mandibulary changes, soft tissue in the mouth, teeth/dental abnormalities, fingertip changes, knee and scapula deformities, hearing abnormalities, and neurological and, more important, severe psychological problems., Design, Setting, Patients: In the past 8 years, we have encountered 40 cases of SS in SH and CKD by performing an international study in Turkey, India, Romania, Egypt, Maleysia, Tunis, and China., Results: The medical history of these patients showed that they did not receive proper therapy. Changes, particularly in children and teenagers, become irreversible, which was disastrous for the patients both aesthetically and psychologically., Conclusion: Treatment must begin early and be the appropriate treatment given in centers with sophisticated skills. Otherwise, the inability to correct all the changes in the skull and face, to remodel a new face, to extending the height, and, most important, to convince the patients to face the dramatic psychological problems can be catastrophic for those patients.

Patients with chronic renal failure (CRF) often have signs and symptoms related to fluid and electrolyte disturbances, anemia, malnutrition, bone disease, and gastrointestinal problems. Vascular and neurologic impairment in particular remain an important source of morbidity and mortality in this vulnerable patient population. Sagliker syndrome is a novel syndrome that was recently described in 2004 in patients with CRF and severe and late secondary hyperparathyroidism who suffered from severe skull and facial bone changes, particularly from uglifying human face appearances and neuropsychiatric disorders. The goal of this study was to assess neuropsychiatric manifestations occurring in CRF patients with Sagliker syndrome. Four female and 8 male patients with CRF on regular dialysis at the hemodialysis units of the Internal Medicine Departments around southern Turkey participated in the study. All patients underwent a clinical neurologic examination performed by the same neurologist. Neuropsychiatric signs and symptoms were found in all cases. The results showed that the most frequent neurologic manifestations in CRF patients with Sagliker syndrome were headache, polyneuropathy, cranial neuropathy, fatigue, and psychiatric disorders.

It is well known that secondary hyperparathyroidism may be an extremely severe condition in chronic renal failure, and almost all patients with chronic kidney disease, even in the well-developed countries, encounter every kind of bone abnormalities if they are not treated properly. Although some sporadic cases have been reported of unique facial bone changes, the largest collection of this phenomenon has been reported by Sagliker et al. We also have found 6 of 9 patients who have these changes (Sagliker syndrome) to manifest class II malocclusion of the upper and lower jaws according to dental universally accepted criteria by performing cephalometric studies, x-ray plain films, tomographic procedures, and drawing technology.

Objective: Cardiovascular complications due to atherosclerosis (AS) are the major cause of mortality in hemodialysis (HD) patients. Inflammation may play an important role in the development of AS. Several studies have demonstrated an association between AS and acute-phase proteins and cytokines in the general population and in HD patients. Interleukin-10 (IL-10) is an anti-inflammatory cytokine. The aim of this study was to compare serum levels of inflammatory and anti-inflammatory indicators in HD patients according to the presence or absence of AS., Material and Methods: A total of 33 HD patients were studied. AS was defined as the presence of plaques as detected by Doppler ultrasonography. The patients were subgrouped according to the presence or absence of plaques. Serum levels of IL-1, -2, -6 and -10, C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-alpha) were measured. Risk factors for AS, such as age, gender, hypertension, hyperlipidemia and duration of HD, were also evaluated., Results: Patients with AS had significantly higher high sensitivity (hs)-CRP and lower IL-10 levels. Blood pressure was also elevated in patients with AS. There was an inverse correlation between CRP and IL-10 levels in patients with AS., Conclusion: Patients with AS undergoing HD had low serum levels of the anti-inflammatory cytokine IL-10 and high serum levels of hs-CRP. These results may suggest that limitation of the anti-inflammatory response in atherosclerotic uremic patients is a triggering or contributory factor for AS.

Almost every patient with chronic renal failure (CRF) eventually develops secondary hyperparathyroidism (SH) unless they are treated with proper and novel medications in advanced medical centers by skilled medical personnel. Every kind of bone abnormality including skull deformities has been described in detail by almost every concerned researcher and textbook, but descriptions of this phenomenon are limited in the medical literature to the years from 1973 to 1977. To our knowledge, extensive data regarding uglifying human face appearances have not been defined so far in the literature. We are therefore making this addition to the clinical nephrology field by accumulating such data. After we found 2 consecutive peculiar and unique patients with uglifying human face appearances in 2000, we attempted to inform and draw attention to this new entity to all hemodialysis (HD) centers in Turkey, as well as in other developing countries around the world to collect data on this phenomenon. Accordingly, we visited dialysis centers and patients' houses to collect detailed information, including medical clinical histories, physical examinations, laboratory data, biographies, current medications, and so forth. We found 25 patients who had CRF, SH, short stature, extremely severe skull changes, maxillary and mandibular bone changes, teeth/dental abnormalities, and soft and innocuous tumoral tissues in the mouth (hence, uglifying the appearance of the face), fingertip changes, severe psychologic problems, and depression. It appears that patients with CRF may have a new syndrome of bone deformities that have long been neglected, ignored, and forgotten since the mid-1970s when they were first described. This is vital and critical information for the clinical status of patients who suffered from the syndrome that we have named Sagliker syndrome (SS), and we believe there are many more patients in the world who are suffering from it.

Arteriosclerosis is characterized by stiffening of arteries. The incremental elastic modulus (Einc) measurement is a good marker of arterial wall stiffness. Metabolic, inflammatory and hemodynamic alterations cause structural changes and vascular complications in end stage renal disease. The aim of the present study was to evaluate the factors that may affect the development of arteriosclerosis by measurement of Einc in hemodialysis (HD) patients. Thirty-two patients (16 men; 16 female) on chronic HD with a mean age of 42.2 +/- 19.3 (range: 15-80) were included in the study. The carotid Einc was measured to determine arteriosclerosis by high-resolution echo-tracking system (Acuson Aspen, Acuson Corp., Mountain View, California, USA). Einc measurement was calculated from transcutaneous measurements of common carotid arterial (CCA) internal diameter and wall thickness and carotid pulse pressure. Common carotid compliance and distensibility were determined from changes in carotid artery diameter during systole and simultaneously measured carotid pulse pressure. Common carotid artery stuffiness (Einc) was influenced by age, systolic blood pressure (SBP), pulse pressure (PP), calcium (Ca) and alkaline phosphatase (ALP). The distensibility of CCA was correlated with age, SBP, diastolic blood pressure (DBP), PP, Ca, ALP, and parathormone (PTH). The inflammatory parameter, hs-CRP, was increased with Einc. The mean Einc measurement was found significantly increased in patient receiving vitamin D. In conclusion, the stiffening of carotid artery in HD patients is related not only to hemodynamic changes (increased SBP, PP) but also to metabolic (increased Ca) and to inflammation (increased hs-CRP). Carotid Einc is accepted independent risk factor for cardiovascular mortality. Because of the positive correlation between Einc and serum Ca, vitamin D and Ca containing phosphorus (P) binders should be used carefully.

Objective: Autonomic neuropathy and impairment of left ventricular functions (LVF) have been frequently encountered in chronic renal failure (CRF). The aim of the present study was to evaluate the relationship of cardiac autonomic modulation impairments, as assessed by means of heart rate variability (HRV), with clinical characteristics, and left ventricular function in the patients with CRF undergoing hemodialysis (HD)., Methods: Twenty control subjects (Group I) and 22 comparable by age and gender patients with CRF undergoing hemodialysis (Group II) were enrolled in the study. After routine clinical and biochemical evaluations, electrocardiography, and 2 Dimensional, M Mode echocardiography were performed in all participants. Frequency domain HRV analysis was studied by using Kardiosis System. The powers (P1 and P2) and the central frequencies (F1 and F2) of low and of high frequency spectral bands were recorded., Results: End systolic (ESV) and end diastolic volumes (EDV) were significantly higher in Group II (59.3 +/- 21.1mL vs. 34.0 +/- 14.3 mL and 131.5 +/- 37.3 mL vs. 96.9 +/- 18.9 mL, p < 0.01, p < 0.05, respectively) when compared to those of Group I. Ejection fraction (EF) and fractional shortening (FS) were significantly lower in Group II than in control subjects (52.3 +/- 2.4% vs. 63.7 +/- 10.1% and 0.29 +/- 0.01 vs. 0.34 +/- 0.07, p < 0.001, p < 0.05, respectively). P and P2 were decreased in Group II than in Group I (136.2 +/- 173.9 m s2 vs. 911.0 +/- 685.5 and 96.5 +/- 149.6 vs. 499.7 +/- 679.5, p < 0.001, p < 0.01, respectively). Significant correlations were found between high frequency spectral power and dialysis duration (DD), ESV, EDV, EF, FS (r = 0.52 p < 0.01, r = 0.68 p < 0.001, r = 0.65 p < 0.002, r = 0.66 p < 0.02, and r = 0.69 p < 0.01)., Conclusion: As a result, the dependence of cardiac autonomic neuropathy on the disease duration and degree of left ventricular function impairment was shown in the patients undergoing chronic hemodialysis.
