Health-related quality of life after kidney transplantation in comparison intermittent hemodialysis, peritoneal dialysis, and normal controls.

The purpose of this study was to compare the quality of life (QOL) in renal transplantation patients. QOL is one of the important indicators of the effects of medical treatment. In this cross-sectional study, QOL was analyzed in 302 renal transplant recipients compared with 64 hemodialysis (HD) patients, 207 (PD) peritoneal dialysis patients, and 278 normal controls (NC) matched as closely as possible to the grafted patients regarding age, gender, education, and occupation. All groups were asked to estimate their subjective QOL by responding to sociodemographic data, Turkish adapted instruments of the Nottingham Health profile (NHP), and the Short-form 36 (SF-36). Transplant recipients were significantly younger than the HD and PD patients (P < .0001). There was no statistically significant differences between normal controls and transplant patients ages. Among the three renal replacement methods, QOL in transplants was clearly better than that in HD or PD patients (P < .0001). The QOL measured by the NHP and SF-36 scale showed that the normal population was statistically significantly better than the transplant recipients (P < .0001). Transplant renal replacement therapy provides a better QOL compared with other replacement methods.

Severe vitamin D deficiency in chronic renal failure patients on peritoneal dialysis.

UNLABELLED: The aim of this study was to evaluate the prevalence of vitamin D deficiency in chronic renal failure (CRF) patients on peritoneal dialysis (PD) and to correlate the findings with various demographic and renal osteodystrophy markers. METHOD: This cross-sectional, multicenter study was carried out in 273 PD patients with a mean age of 61.7 +/- 10.9 years and mean duration of PD 3.3 +/- 2.2 years. It included 123 female and 150 male patients from 20 centers in Greece and Turkey, countries that are on the same latitude, namely, 36-42 degrees north. We measured 25(OH)D3 and 1.25(OH)2D3 levels and some other clinical and laboratory indices of bone mineral metabolism. RESULTS: Of these 273 patients 92% (251 patients) had vitamin D deficiency i.e. serum 25(OH)D3 levels less than 15 ng/ml, 119 (43.6%) had severe vitamin D deficiency i.e., serum 25(OH)D3 levels, less than 5 ng/ml, 132 (48.4%) had moderate vitamin D deficiency i.e., serum 25(OH)D3 levels, 5-15 ng/ml, 12 (4.4%) vitamin D insufficiency i.e., serum 25(OH)D3 levels 15 - 30 ng/ml and only 10 (3.6%) had adequate vitamin D stores. We found no correlation between 25(OH)D3 levels and PTH, serum albumin, bone alkaline phosphatase, P, and Ca x P. In multiple regression analyses, the independent predictors of 25(OH)D3 were age, presence of diabetes (DM-CRF), levels of serum calcium and serum 1.25(OH)2D3. CONCLUSION: We found a high prevalence (92%) of vitamin D deficiency in these 273 PD patients, nearly one half of whom had severe vitamin D deficiency. Vitamin D deficiency is more common in DM-CRF patients than in non-DM-CRF patients. Our findings suggest that these patients should be considered for vitamin D supplementation.

Lessons learned from the catastrophic Marmara earthquake: factors influencing the final outcome of renal victims.

BACKGROUND: During catastrophic earthquakes, crush syndrome is the second most frequent cause of death after the direct impact of trauma. The Marmara earthquake, which struck Northwestern Turkey in August 1999, was characterized by 639 crush syndrome victims with acute renal problems. The factors influencing their final outcome have been the subject of this study. PATIENTS/METHODS: Within the first week of the disaster questionnaires asking about 63 clinical and laboratory variables were sent to 35 reference hospitals that treated the victims. Information obtained by means of these questionnaires, including the factors with a potential influence on outcome, was submitted to analysis. RESULTS: Overall mortality rate was 15.2%. In univariate analysis, nonsurvivors were older (p = 0.048); the highest mortality rates were observed among the victims coming from the closest cities to the reference hospitals. Admission within the first 3 days of the disaster (p = 0.016), with oliguria (p = 0.042), lower figures for blood pressure (p < 0.001), platelets (p = 0.004) and serum albumin (p = 0.005) were associated with mortality. Also, higher body temperature (p = 0.013) and serum potassium (p < 0.001) as well as suffering from thoracic or abdominal traumas, extremity amputations and medical complications other than renal failure (for all 4: p < 0.0001) in addition to need of dialysis support (p = 0.015) and mechanical ventilation (p < 0.0001) indicated higher risk of death. In the multivariate analysis, age (p = 0.030, OR = 1.02), presence of disseminated intravascular coagulation (p = 0.001, OR = 4.49), abdominal trauma (p = 0.012, OR = 4.05) and amputations (p = 0.010, OR = 2.81) were predictors of mortality. Dialyzed patients were characterized by higher mortality rates than nondialyzed victims (17.2% versus 9.3%, p = 0.015). CONCLUSION: Outcome of the renal victims of catastrophic earthquakes is influenced by the type of trauma, comorbid events and complications observed during the clinical course as well as epidemiological features such as age, distance to reference hospitals and time lapse between disaster and admission to reference hospitals.

Acute renal failure due to carnitine palmitoyltransferase II deficiency.

Carnitine palmitoyltransferase II (CPT-II) deficiency is the most common long-chain fatty acid oxidation defect, resulting in rhabdomyolysis and acute renal failure (ARF). There are three forms of CPT-II deficiency: the neonatal, infantile and adult form. We report an adult form of CPT-II deficiency in a patient who presented with attacks of exercise-induced rhabdomyolysis and ARF.

Amyloid goitre in familial Mediterranean fever: report on three patients and review of the literature.

Familial Mediterranean fever (FMF) is a hereditary disease, the most threatening complication of which is systemic amyloidosis. The thyroid gland may be asymptomatically involved in most patients with systemic amyloidosis secondary to FMF. However, clinically detectable thyroid goitre is quite rare, and until now only nine cases of thyroid goitre secondary to amyloid deposition in FMF have been reported. Of 1,100 FMF patients regularly followed up at our centre, thyroid goitre due to the accumulation of amyloid substance could be detected in only three (0.27%). In this report, we summarise the clinical and laboratory features of these patients. All three patients were euthyroid. Total thyroidectomy was performed for compressive symptoms in one patient and for aesthetic purposes in the other two. In countries with a high prevalence of FMF, such as Turkey, secondary amyloidosis of the thyroid gland should be borne in mind in long-standing FMF patients.

Fever of unknown origin in uremic patients: a controlled prospective study.

Twenty-nine uremic patients with fever of unknown origin (FUO) admitted to our clinic between 1994 and 1998 were evaluated prospectively. A group of 50 consecutive non-uremic patients with FUO followed up during the same period was used for comparison. The causes of FUO found in the uremic and non-uremic groups, respectively were as follows: infectious diseases, 69 vs. 44% (p = 0.03); collagen vascular diseases, 6.9 vs. 6%; neoplasms, 3.4 vs. 26%; miscellaneous causes, 3.4 vs. 16%; and undiagnosed, 17.2 vs. 8%. Tuberculosis was the most common cause of FUO in both groups. The spectrum of underlying conditions for FUO in our uremic patients differed from that in the non-uremic patients and the uremic patients had a very high propensity for infectious diseases, especially tuberculosis.

Mycobacterium tuberculosis infections after renal transplantation.

The incidence of tuberculosis was found to be 5.8% (16/274) in 274 kidney graft recipients in our centre between 1986 and 1998. The kidney recipients were evaluated retrospectively. A total of 51 recipients received isoniazid prophylaxis for 6 months. The prevalence of tuberculosis was found similar (6% vs. 8.8%, p = 0.15) between recipients with prophylaxis and no prophylaxis. Eight patients were recipients of cadaveric donor kidneys and 8 were recipients of living donor kidneys. Lungs were the most frequently affected site, as in the normal population. M. tuberculosis grew in 7 patients. In 5 patients, M. tuberculosis was also detected on direct microscopy and polymerase chain reaction. In 4 patients, diagnosis was made on clinical grounds and later confirmed by positive response to therapy. In 8 patients, invasive procedures were performed for diagnosis. Five patients had miliary tuberculosis at the time of diagnosis. In 3 patients dissemination occurred during follow-up. Nine patients responded to anti-tuberculous therapy while still preserving their graft function, 1 patient rejected the graft while under treatment and returned to haemodialysis. Five patients (31%) died. Since the risk of dissemination of tuberculosis is high in these patients, anti-tuberculous therapy should be started whenever clinical findings suggestive of tuberculosis are present, even in the absence of any microbiological and/or histological evidence.

Long-term CAPD--some U.K. experience.

As many UK renal units commence more patients on CAPD than hemodialysis (HD) as the first mode of therapy a retrospective study of long-term CAPD (greater than 4 years continuous CAPD) was performed in 4 centers with substantial CAPD programs. One hundred and seventy-seven patients (103M, 74F) started CAPD before December, 1981. There was no difference in primary renal disease. Age was significantly greater in 2 units (51.9 +/- 11.7 and 53.2 +/- 12.1 vs 40.6 +/- 16.2 and 42.5 +/- 14.6 years, p less than 0.05) and correlates with pre-CAPD activity scores (Scale 3-0). After 4 years: 34 patients (19.2%) remained on CAPD: the proportion was similar in all centers. Sixty-five percent of patients were alive but 54% transferred to HD mainly due to peritonitis (overall 2.0 episodes/intercenter variation p less than 0.001). Fourty-four patients were transplanted. Significant increases occurred in hemoglobin, albumin, calcium and creatinine; a decrease in activity score (2.4 +/- 0.7 to 1.5 +/- 0.9, p less than 0.005); no change in weight, BP, urea or bone disease. Thirty-eight patients died, mainly cardiac (14) or sepsis (11). Using Cox's method of analysis significant risk multipliers were age (2.07 per decade), male sex (2.18), frequency of peritonitis (1.36), activity score less than 2 (4.45) and amyloidosis (12.45). Despite differing techniques in different centers CAPD offered a satisfactory mode of therapy for many patients; peritonitis was the main reason for transfer to HD and several significant factors were identified.

Prevalence of serum antibodies to hepatitis B and C viruses in patients with primary glomerulonephritis.

We retrospectively analysed the medical records of patients who underwent renal biopsy in our nephrology department over the past 8 years. Our aim was to discover the frequency of hepatitis B (HBV) and hepatitis C virus (HCV) in patients with primary glomerulonephritis (GN) in Turkey, a moderately endemic country for both infections. The study included 144 male and 104 female patients aged between 12-70 years. The frequency of HBsAg and anti-HCV were found to be similar to healthy controls, respectively 6.5% and 1.6% (p>0.05). As is true for low endemic countries, HBV and HCV infections might be rarely associated with GN in Turkey.

Colchicine neuromyopathy: a report of six cases.

Colchicine has been in use for therapeutic purposes for many years. It can, however, cause subacute onset muscle and peripheral nerve toxicity in patients with chronic renal failure. In this report we describe 6 patients who developed neuromyopathy after the administration of colchicine. All patients presented with proximal muscle weakness, elevated serum creatine kinase (CK) levels, and neuropathy and/or myopathy on electromyography (EMG). The diagnosis of colchicine toxicity was confirmed in all cases by the normalization of CK levels and EMG after discontinuation of the drug. Toxicity developed in 4 renal failure patients on therapeutic doses of the drug, while one patient took a massive dose for suicidal reasons, and the other was on high-dose therapy. Patients using colchicine--especially those with renal failure--should be warned about the side effects of the drug and physicians should be careful in the administration of the drug.
