RESUMEN
Documenting primate life history characteristics is important because it provides information about traits that affect the timing and rate of reproduction in these long-lived species. This study describes the hormonal correlates of female reproductive events and quantifies for the first time key life history variables for Colobus vellerosus, using hormonal and observational data. This study also biologically validates that the reproductive events determined in the hormone profiles correspond to observed reproductive events for each female. We collected behavioural data on 18 females in our four study groups during 12 months (May 2012-2013) at the Boabeng-Fiema Monkey Sanctuary, using 10-min continuous focal and ad libitum sampling. We concurrently collected faecal samples (n = 1866) every 2-3 days from these 18 females (prepubescent n = 2, cycling n = 2, lactating n = 12, pregnant, n = 7, and post-reproductive n = 1) and extracted oestrogen (E2) and progesterone (P) metabolites in the field using solid-phase extraction cartridges. We created a hormone profile for each female by analyzing 1586 of our samples for E2 using radio-immuno assays, and P using enzyme-immunoassays at the Wisconsin National Primate Research Center. Mean ovarian cycle length was 24 days ± 1 (n = 2 cycles). Mean gestation length was 23 weeks (range = 21-25 weeks, n = 2 complete pregnancies). For females whose infants survived to nutritional independence, the mean inter-birth interval (IBI) was significantly longer than for females whose infants died prior to reaching nutritional independence (Mann-Whitney U Test; U = 14.5, p = 0.006; IBI surviving infants: 17.75 months, range = 8-20.75 months, n = 11 vs. IBI infant death: 11.89 months, range = 8-18.5 months, n = 9). The values for most life history traits reported in this study are similar to those documented in other similarly sized colobine species. Some values are on the lower end of the range for similarly sized colobines; C. vellerosus shows a cycle of 24 days and gestation length of 5.75 months vs. a range of 24-29 days for cycle length and 5.25-7.5 months for gestation length in other colobines. This may be due to C. vellerosus' smaller body size, or their limited access to higher quality food resources.

OBJECTIVE: Data on transplantation survival is widely available for developed countries where cadaveric transplantation is the dominant transplantation type. We aimed to assess patient and graft survival and to determine the possible factors affecting graft survival in a developing country where kidney transplantations were mainly performed from living donors. METHODS: We retrospectively analyzed data from 427 adult kidney transplantations performed at our center from January 1990 to November 2010. We collected data from patient files, including characteristics of the recipients and donors, transplantation-related factors, post-transplantation features, causes of graft loss, and patient death. The Kaplan-Meier method was used to analyze survival, and Cox regression analysis was used to evaluate the effects of multiple factors on graft survival. RESULTS: Most of the recipients (82.6%) received their organs from living donors. One-year and 5-year graft survival rates were 87.5% and 78.3%, respectively, where the 5-year graft survival rates were 87.1% for living donors and 74.8% for cadaveric donors. The 1-year and 5-year patient survival rates were 90.9% and 88.9%, respectively. Univariate analysis showed that predictors for better graft survival were serum creatinine levels <1.5 mg/dL at 1 month after transplantation, proteinuria <500 mg/d at 1 year after transplantation, use of tacrolimus and mycophenolic acid derivative-based immunosuppression at baseline, living-donor transplantation, and transplantations performed in the years 2000-2010. CONCLUSIONS: We report data on kidney transplantation in an emerging country where living-donor transplantation constitutes a large proportion of kidney transplant activities. Modern immunosuppressive medications help to achieve a better survival. Our 5-year results are similar to those of developed countries.

Aim: Peritonitis is one of the major comorbidities of peritoneal dialysis (PD) patients. The aim of this study was to concentrate on potential risk factors, including more recently studied ones among the classical ones for peritonitis, in PD patients. Materials and methods: We analysed 109 patients (F/M = 42/67) followed up at least for 3 months in a single centre, a tertiary referral hospital for 360.1 patient years. In the study which is designed as a retrospective cohort study, demographic characteristics, conditions for choosing PD, type of PD treatment, some chemical tests and peritonitis episodes were recorded from the files of the patients. Results: The rate of peritonitis was found to be 0.22 episode/patient year and 22 (20.18%) of the patients had more than one episode. Twenty seven (24.8%) of the patients were allocated to PD due to obligatory reasons. According to multiple regression analysis, the assosciated factors were found to be PD allocation type (obligatory versus voluntary) (p = 0.04; RR = 2.6), serum albumin level (p = 0.05; RR = 1.2), and anti-hepatitis C Virus Antibody positivity (p = 0.03; RR = 1.6). Frequency of female patients were significantly higher in the group who had multiple episodes (p = 0.01). Conclusion: Obligatory referral which can be an indication of loss of motivation for peritoneal dialysis procedures, is thought to be a strong risk factor for peritonitis in PD patients and should be further studied. Patients with multiple episodes had a higher frequency of obligatory referral as expected and additionally, they were higher in number of females when compared to the ones with single episode (AU)
Objetivo: La peritonitis es una de las principales comorbilidades que presentan los pacientes en diálisis peritoneal (DP). El objetivo de este estudio es centrarnos en los posibles factores de riesgo, incluidos los de más reciente estudio entre los ya clásicos factores de la peritonitis en pacientes en DP. Materiales y métodos: Analizamos 109 pacientes (H/M = 67/42) sometidos a seguimiento durante al menos tres meses en un único centro, un hospital terciario con una tasa de 360,1 años-paciente. En este trabajo, concebido como un estudio de cohorte retrospectivo, se registraron las características demográficas, las condiciones que llevaron a la DP, tipo de DP, pruebas químicas y episodios de peritonitis. Esta información se extrajo de los historiales. Resultados: Se descubrió que la tasa de peritonitis era de 0,22 episodios/años-paciente y 22 pacientes (20,18%) habían padecido más de un episodio. Veintisiete (24,8%) de los pacientes recibían DP por obligación. Gracias al análisis de regresión múltiple, se descubrió que los factores relacionados eran el tipo de llegada al tratamiento (obligatoria frente a voluntaria) (p = 0,04; RR = 2,6), los niveles de albúmina sérica (p = 0,05; RR = 1,2), y la positividad para anticuerpos contra el virus de hepatitis C (p = 0,03; RR = 1,6). La frecuencia de pacientes mujeres era significativamente mayor en el grupo que había padecido múltiples episodios (p = 0,01). Conclusión: La remisión obligatoria, que puede ser un indicio de la falta de motivación por los procedimientos de DP, es un importante factor de riesgo de peritonitis en los pacientes en DP y merece ser objeto de estudio. Como era de esperar, los pacientes con múltiples episodios presentaron una mayor frecuencia de remisión obligatoria y además, el número de mujeres era mayor en comparación con el grupo que había padecido un único episodio (AU)

We compared the tolerability and efficacy of mycophenolate mofetil (MMF) versus mycophenolate sodium (MPS) among renal transplant recipients on tacrolimus-based immunosuppression. The 105 patients who underwent kidney transplantation between January 2002 and March 2008 and were treated with steroid, tacrolimus, and a mycophenolic acid compound were enrolled in the study. From patient files we collected on demographics data, donors, immunosuppressive drug doses, biochemical and hematologic parameters, gastrointestinal and hematologic side effects, and kidney function. Fifty-six patients were prescribed MMF and 49 of them were taking MPS. Demographic parameters and pretransplantation dialysis duration were similar between the 2 groups. After the third month, the MPS dose was higher than that of MMF. There were no clinically important differences between the 2 groups, regarding other immunosuppressive drug doses. Gastrointestinal side effects were similar: 42.4% in the MMF versus 44.8% in the MPS group (P = .846). Six patients in the MMF group and 1 patient in the MPS group underwent a switch of the mycophenolic acid therapy due to severe gastrointestinal side effects (P = .183). Biopsy-proven acute rejection was reported in 6 patients on MMF and 7 patients on MPS therapy (P = .768). The log-rank test evaluating a 50% reduction in glomerular filtration rate (GFR) showed no significant difference between the 2 groups (P = .719). No deaths were recorded during the study period; there was only 1 graft loss, which occurred in the MMF group. We did not observe a significant difference in tolerability and efficacy between the 2 widely used mycophenolic acid derivatives. Economic considerations can be an important factor when choosing the drug.

Hyperphosphatemia is independently associated with an increased risk of death among dialysis patients. In this study, we have assessed the status of phosphate control and its clinical and laboratory associations in a large international group of patients on chronic peritoneal dialysis (PD) treatment. This cross-sectional multicenter study was carried out in 24 centers in three different countries (Canada, Greece, and Turkey) among 530 PD patients (235 women, 295 men) with a mean+/-s.d. age of 55+/-16 years and mean duration of PD of 33+/-25 months. Serum calcium (Ca(2+)), ionized Ca(2+), phosphate, intact parathyroid hormone (iPTH), 25-hydroxy vitamin D(3), 1,25-dihydroxy vitamin D(3), total alkaline phosphatase, and bone alkaline phosphatase concentrations were investigated, along with adequacy parameters such as Kt/V, weekly creatinine clearance, and daily urine output. Mean Kt/V was 2.3+/-0.65, weekly creatinine clearance 78.5+/-76.6 l, and daily urine output 550+/-603 ml day(-1). Fifty-five percent of patients had a urine volume of <400 ml day(-1). Mean serum phosphorus level was 4.9+/-1.3 mg per 100 ml, serum Ca(2+) 9.4+/-1.07 mg per 100 ml, iPTH 267+/-356 pg ml(-1), ionized Ca(2+) 1.08+/-0.32 mg per 100 ml, calcium phosphorus (Ca x P) product 39+/-19 mg(2)dl(-2), 25(OH)D(3) 8.3+/-9.3 ng ml(-1), 1,25(OH)(2)D(3) 9.7+/-6.7 pg ml(-1), total alkaline phosphatase 170+/-178 U l(-1), and bone alkaline phosphatase 71+/-108 U l(-1). While 14% of patients were hypophosphatemic, with a serum phosphorus level lower than 3.5 mg per 100 ml, most patients (307 patients, 58%) had a serum phosphate level between 3.5 and 5.5 mg per 100 ml. Serum phosphorus level was 5.5 mg per 100 ml or greater in 28% (149) of patients. Serum Ca(2+) level was > or =9.5 mg per 100 ml in 250 patients (49%), between 8.5 and 9.5 mg per 100 ml in 214 patients (40%), and lower than 8.5 mg per 100 ml in 66 patients (12%). Ca x P product was >55 mg(2)dl(-2) in 136 patients (26%) and lower than 55 mg(2)dl(-2) in 394 patients (74%). Serum phosphorus levels were positively correlated with serum albumin (P<0.027) and iPTH (P=0.001), and negatively correlated with age (P<0.033). Serum phosphorus was also statistically different (P = 0.013) in the older age group (>65 years) compared to younger patients; mean levels were 5.1+/-1.4 and 4.5+/-1.1 mg per 100 ml, respectively, in the two groups. In our study, among 530 PD patients, accepted uremic-normal limits of serum phosphorus control was achieved in 58%, Ca x P in 73%, serum Ca(2+) in 53%, and iPTH levels in 24% of subjects. Our results show that chronic PD, when combined with dietary measures and use of phosphate binders, is associated with satisfactory serum phosphorus control in the majority of patients.

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.

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.

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.

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.

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.

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.

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.

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.

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.
