RESUMO
OBJECTIVE: Postoperative pancreatic fistula (POPF) is the most common and critical complication of pancreatoduodenectomy (PD). In this study, we aimed to define preoperative, perioperative, and postoperative conditions that may cause POPF and examine the predictive value of drain fluid amylase (DFA) values in showing the clinical severity of POPF. PATIENTS AND METHODS: Between December 2018 and December 2019, 49 patients who underwent PD for malignant reasons by a single team were retrospectively analyzed. Patients with benign indications, vascular reconstruction, preoperative biliary drainage catheterization, resectable liver metastases, POPF that occurred after reoperation, and patients undergoing neoadjuvant oncological treatment were excluded from the study. The patients were divided into two groups developing (FP) and non-developing (FN) POPF. RESULTS: There was no difference between the groups in terms of gender (p=0.781), age (p=0.219), American Society of Anesthesiologists (ASA) score (p=0.338), and comorbidity status (p=0.219). The mean body mass index (BMI) kg/m2 values of the patients in the FN and FP groups were 25.2±4.0 kg/m2 and 27.4±2.6 kg/m2, respectively (p=0.042). An increased BMI increases the risk of POPF. Preoperative prognostic nutritional index (PNI) score (p=0.588), preoperative total bilirubin level (p=0.707), pancreatic duct diameter (p=0.334), pancreatic texture (p=0.334), operation time (p=0.659) do not pose a risk for POPF. Increased perioperative bleeding amounted to a risk for POPF (123.8±46.7 ml, 244.7±66.3 ml in FN and FP groups, respectively, p=0.024). Drain fluid amylase (DFA) values (p<0.001, p=0.043, p=0.019, respectively) were found to be high in patients with POPF on postoperative days 1, 4, and 7. CONCLUSIONS: Increased BMI and excess perioperative blood loss increase the risk of POPF. DFA level is an easily applicable method that provides early diagnosis for POPF.

ABSTRACT Introduction: High uric acid levels are commonly encountered in kidney transplant recipients, and can be associated with allograft dysfunction. Our study aims to examine the relationship between UA levels and graft function in patients discontinuing steroids. Methods: In this single-center-retrospective study, 56 patients discontinued steroid therapy from among 678 RT patients transplanted from living donors between 1999-2020 were included. The mean age of the study group was 45.8±8.8 years. Causes of steroid discontinuation, creatinine levels concurrent with uric acid levels before and after steroid discontinuation (mean 3.9 ± 2.1 years), acute rejection numbers, demographics, durations of dialysis and transplantation, medications, laboratory data, human leukocyte antigen (HLA) mismatch numbers, blood-pressure (BP), body mass index, delayed acute rejection (DAR) numbers (3 months post-transplantation) were all recorded. Results: Creatinine and uric acid levels were seen to have increased after steroid discontinuation, there was a significant relationship between them (p<0.001). Statistically significant correlation was found between increased creatinine levels after steroid discontinuation and graft survival with higher HLA mismatch; 39 (69.6%) patients with mismatch ≥2, and 17 patients with mismatch <2 (30.4%) (p=0.049) . No significant relationship was found between DAR numbers before and after steroid discontinuation, and creatinine levels after steroid discontinuation. Conclusion: Per model obtained as a result of multivariate linear analysis, hyperuricemia and HLA mismatch numbers (p= 0.048 and p= 0.044, respectively) are independent predictive factors for graft dysfunction in patients discontinuing steroids. Accordingly, negative effects of modeling should be kept in mind for long-term graft survival in patients who plan to continue with steroid-sparing regimens.
RESUMEN Introducción: Con frecuencia se registran niveles elevados de ácido úrico en receptores de trasplantes renales que pueden estar asociados a disfunción de aloinjerto. El presente estudio tiene por objeto examinar la relación entre los niveles de AU y la función del injerto en pacientes que interrumpieron la terapia con esteroides. Métodos: En este estudio retrospectivo en un solo centro participaron 56 pacientes con interrupción de la terapia con esteroides de un total de 678 pacientes con TR receptores de trasplante de donantes vivos en el período 1999-2020. La edad promedio de la población de estudio fue de 45,8 ± 8,8 años. En el estudio se registraron causas de la interrupción de la terapia con esteroides, niveles de creatinina concurrentes con niveles de ácido úrico antes y después de la interrupción de la terapia con esteroides (promedio de 3,9 ± 2,1 años), números de rechazo agudo, datos demográficos, duraciones del período de diálisis y trasplante, medicación (uso de inmunosupresores, antihipertensivos), datos de laboratorio, números de desajuste del antígeno leucocitario humano (HLA), presión arterial (PA), índice de masa corporal, números de rechazo agudo retardado (DAR) (3 meses después del trasplante). Resultados: Se observó que los niveles de creatinina y ácido úrico aumentaron tras interrumpir la administración de esteroides, con una relación significativa entre ambos (p<0,001). Se identificó una correlación estadísticamente significativa entre el aumento en los niveles de creatinina tras la interrupción de la terapia de esteroides y la supervivencia del injerto con un mayor desajuste de HLA: 39 pacientes (el 69,6%) con desajuste ≥2 y 17 (el 30,4%) pacientes con desajuste <2 (p=0,049). No se encontró una relación significativa entre el número de DAR antes y después de la interrupción del tratamiento con esteroides, así como en los niveles de creatinina tras la interrupción de la terapia con esteroides. Conclusión: De acuerdo con el modelo obtenido como resultado del análisis lineal multivariable, la hiperuricemia y los números de desajuste de HLA (p=0,048 y p=0,044, respectivamente) constituyen factores predictivos independientes para la disfunción del injerto en pacientes que interrumpen la terapia con esteroides. En consecuencia, se deben tener en cuenta los efectos negativos del modelado para la supervivencia del injerto a largo plazo en pacientes que planean proseguir con regímenes con reducción de la administración esteroides.
RESUMO
Opioid dependence is an increasing public health problem. One of the complications of intravenous opioid use is hepatitis C virus infection, which, in turn, is one of the most common indications for liver transplantations throughout the world. Therefore, the treatment of opioid dependence in a liver transplant recipient requires special attention in terms of graft function, drug interactions, and patient compliance. Buprenorphine is a semi-synthetic opioid-derived agent with analgesic effects. To prevent buprenorphine abuse, it is combined with the opioid antagonist naloxone. This buprenorphine/naloxone combination is the only drug approved for the treatment of opioid dependence in Turkey. Although the literature includes data about the safe usage of buprenorphine in liver transplantation in animals, there is no such evidence in either case reports or clinical trials for the same in humans. In this article, we present a report of our treatment of 2 opioid-dependent patients with buprenorphine/naloxone after liver transplantation due to hepatitis C virus-induced liver cirrhosis.

INTRODUCTION: Transplantation is the most effective treatment strategy for end-stage renal failure. We aimed to investigate the correlation of volume control parameters with health-related quality of life (HRQoL) in renal transplantation patients during the pre- and post-transplantation periods. MATERIAL AND METHODS: Seventy-seven patients who underwent renal transplantation from deceased donors between January 2011 and January 2013 were included in the study. The biochemical markers, complete blood count, and creatinine levels were measured during pretransplantation and at post-transplantation month 6. The Turkish version of the Short Form 36 (SF-36) health survey questionnaire was used for the assessment of HRQoL. Blood pressure (BP) and echocardiographic measurements were used to evaluate the volume status. RESULTS: Significant improvements were achieved in all echocardiographic measurements, biochemical parameters except Ca(++), and SF-36 questionnaire domain scores (DSs) except vitality in the post-transplantation period. Systolic BP (SBP), the left atrium index, vena cava inferior collapsibility index (VCCI), and diastolic BP were associated with vitality (P = .02, .03, .05, and .04, respectively); SBP was associated with social functioning (P < .01) and role emotional (P < .01); and left ventricular mass index was associated with mental health (P = .05) DSs during the pretransplantation period. In the post-transplantation period, VCCI, left ventricular mass index, and SBP were associated with general health (P = .02, .05, and .05, respectively); VCCI and SBP were also associated with mental health (P = .05 and .01, respectively); and left atrium index was associated with role emotional (P = .05) DSs. CONCLUSION: Concomitant improvement in the volemic status may contribute to improvements in HRQoL after renal transplantation.

BACKGROUND: We evaluated the prevalence of pretransplantation and posttransplantation anemia and its effect on serum creatinine levels among living donor kidney transplant recipients. METHODS: We reviewed retrospectively 170 adult patients who underwent living donor kidney transplantation between 1994 and 2009. We defined anemia as hemoglobin (Hb) ≤12 g/dL for women and ≤13 g/dL for men with severe anemia as Hb <11 g/dL for both men and women (World Health Organization criteria). Patients were also categorized according to Hb levels less than or greater than 10 g/dL for correlation with recipient serum creatinine levels at months 1, 3, 6, and 12. RESULTS: Mean recipient and donor ages were 33 ± 10 and 45 ± 12 years, respectively. Mean cold ischemia time was 76 ± 43 minutes. At the time of transplantation, anemia and severe anemia prevalences were 86.7% and 58.8%, respectively. Anemia was observed in 64 patients (42.1%) at posttransplantation month 3. Pretransplantation severe anemia was a good predictor of both Hb levels and anemia presence posttransplantation. Pretransplantation anemia and severe anemia caused greater requirements for posttransplantation blood transfusions (P < .05). Younger age and female gender were significant risk factors for severe anemia pretransplantation. There was a significant correlation between posttransplantation Hb levels and serum creatinine levels at 12 month (P = .01). Recipient female gender and longer hospital stay were significant risk factors for both anemia and severe anemia posttransplantation. Higher recipient weight and history of acute rejection episode were also significant for posttransplantation severe anemia. CONCLUSION: This study indicated that successful kidney transplantation had a positive effect on Hb levels. Posttransplantation anemia predicted worse graft function in the first month after transplantation.
