Prognostic value of transthoracic echocardiography and biomarkers of cardiac dysfunction in community-acquired pneumonia.

The aim of this study was to determine the prognostic role of echocardiography and compare with admission N-terminal proB-type natriuretic peptide (NT-proBNP) levels in adult patients with community-acquired pneumonia (CAP). Consecutive adult patients hospitalized with CAP were prospectively enrolled and followed-up until hospital discharge or death. Echocardiography was performed within the first 48 hours. Complicated hospitalization (CH) was defined as intensive care unit admission, need for mechanical ventilation or in-hospital mortality. This study was registered with ClinicalTrials.gov, number NCT02441855. A total of 15 CH (13.5%) occurred among 111 patients with CAP. CAP patients with a CH compared with those without CH had significantly higher NT-proBNP values (1267.4±1146.1 vs. 305.6±545.7 pg/mL, p <0.001) and troponin I (23.8±24.3 vs. 10.3±6.3 ng/mL, p 0.02) but had lower left ventricle ejection fraction (52.7±8.7 vs. 60.5±6.7%, p <0.001) and tricuspid annular plane systolic excursion (TAPSE), which is a measure of right ventricular systolic function (17.1±4.4 vs. 21.8±4 mm; p 0.001). Patients with elevation of NT-proBNP and decreased TAPSE at presentation had a significantly higher probability of CH (60%) than patients with either elevated NT-proBNP or decreased TAPSE (40%). Patients with neither elevated NT-proBNP nor decreased TAPSE had a 0% probability of CH. This is the first study to demonstrate that decreased right ventricular systolic function is associated with increased rates of adverse events in patients with CAP.

Do obesity and age effect the clinicopathological features and survival outcomes in premenopausal women with endometrial cancer?

PURPOSE: The purpose of this study was to review the effect of age and body mass index (BMI) on the prognosis, demographic characteristics, and pathological features of patients diagnosed with endometrial cancer, specifically before menopause. MATERIALS AND METHODS: Patients that were diagnosed with endometrial cancer before menopause, were screened retrospectively. Between 1999 and 2011, 163 patients were identified while 40 were excluded. Patients were classified into three groups according to age (under 40 years, between 40-45 years, more than 45 years) and BMI (normal weight group, overweight group, and obese weight group). Demographical characteristics, histopathological features (Stage, grade and histology of the tumor, the presence of myometrial and/or lymphovascular invasion, history of diabetes mellitus, history of hypertension, hormonal contraception method, smoking, parity, infertility, family history, and recurrences) and survival rates were compared among the groups. RESULTS: In total, 123 patients with a mean of 65.0 months follow up were enrolled into the study. The majority of the patients had endometrioid type in all age-related subgroups. Advanced stage endometrium cancer (Stage 2 and greater) was seen more commonly in the group of patient over 45 years of age against the other age-related subgroups (27.9% vs. 8% vs. 3.3%). Ratio of myometrial invasion more than 50% and occurrence of well-differentiated tumor were seen with a similar ratio among the age-related subgroups. Ratio of nulliparity and infertility were found statistically significant in the group of patients under 45 years of age against the group of patients over 45 years of age (p = 0.001, p = 0.03). The five-year estimated disease-free survival rates of women under 40 years of, women with an age between 40-45 years, and women over the age of 45 years were calculated as 73%, 95%, and 87%, respectively (p = 0.152). Concerning the histopathological features, there were no statistical differences between weight related subgroups. Comorbid conditions (hypertension and diabetes mellitus) were found as statistically high in the obese patients' group (43.5%-25.8%). In contrast to comorbid conditions, nulliparity and infertility histories were observed more often within the normal weight group (55.6%-38.5%). Mean disease-free survival time was calculated as 155.81 months in the normal weight group; 114.691 months in the overweight group, and 144.677 months in the obese group. Five-year disease-free survival rate was calculated as 91%, 81%, and 87%, respectively (p = 0.452). CONCLUSION: Women with premenopausal cancers generally exhibit early and favorable histopathological symptoms. Although advanced stage endometrium cancer incidence was detected to be higher in the premenopausal endometrium cancer patients aged above 45 years compared to other age subgroups. A significant difference in terms of survival rates between these groups was not reached. In the same manner, the authors did not find a significant difference in survival rates among different weight subgroups of premenopausal endometrium cancer patients. As a secondary result, the authors discovered that diabetes mellitus and hypertension play a key role in patients with a BMI above 30 kg/m2 and nulliparity and infertility play a key role in patients with a BMI below 25 kg/m2 in the development of premenopausal endometrial cancer.

Infections in travellers returning to Turkey from the Arabian peninsula: a retrospective cross-sectional multicenter study.

Mass gatherings pooling people from different parts of the world-the largest of which is to Mecca, Saudi Arabia, for Hajj-may impose risks for acquisition and dissemination of infectious diseases. A substantial number of pilgrims to Hajj and Umrah are Turkish citizens (456,000 in 2014) but data are lacking on scale of the problem. We did a retrospective cross-sectional multicenter study in Turkey to explore the range of infections among inpatients who had recently returned from the Arabian Peninsula. Our inclusion criteria were patients who had acquired an infection during their trip to an Arabian Peninsula country, or who became symptomatic within 1 week of their return. The data were collected retrospectively for January 1, 2013 and March 1, 2015. 185 Turkish patients were recruited to the study across 15 referral centers with travel associated infectious diseases after returning from Arabian Peninsula countries (predominantly Saudi Arabia 163 [88.1 %] for religious purposes 162 [87.5 %]). Seventy four (40.0 %) of them were ≥ 65 years old with numerous comorbidities including diabetes (24.3 %) and COPD (14.1 %). The most common clinical diagnosis was respiratory tract infections (169 [91.5 %]), followed by diarrheal diseases (13 [7 %]), and there was one case of MERS-CoV. Patients spent a median of 5 (3-7) days as hospital inpatients and overall mortality was 1.1 %. Returning travellers from the Arabian Peninsula present as inpatients with a broad range of infectious diseases similar to common community acquired infections frequently seen in daily medical practices in Turkey.

Genitourinary brucellosis: results of a multicentric study.

This study reviewed the clinical, laboratory, therapeutic and prognostic data on genitourinary involvement of brucellosis in this largest case series reported. This multicentre study pooled adult patients with genitourinary brucellar involvement from 34 centres treated between 2000 and 2013. Diagnosis of the disease was established by conventional methods. Overall 390 patients with genitourinary brucellosis (352 male, 90.2%) were pooled. In male patients, the most frequent involved site was the scrotal area (n=327, 83.8%), as epididymo-orchitis (n=204, 58%), orchitis (n=112, 31.8%) and epididymitis (n=11, 3.1%). In female patients, pyelonephritis (n=33/38, 86.8%) was significantly higher than in male patients (n=11/352, 3.1%; p<0.0001). The mean blood leukocyte count was 7530±3115/mm3. Routine laboratory analysis revealed mild to moderate increases for erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). The mean treatment duration and length of hospital stay were significantly higher when there were additional brucellar foci (p<0.05). Surgical operations including orchiectomy and abscess drainage were performed in nine (2.3%) patients. Therapeutic failure was detected in six (1.5%), relapse occurred in four (1%), and persistent infertility related to brucellosis occurred in one patient. A localized scrotal infection in men or pyelonephritis in women in the absence of leucocytosis and with mild to moderate increases in inflammatory markers should signal the possibility of brucellar genitourinary disease.

Liver involvement in patients with brucellosis: results of the Marmara study.

Brucellosis is a zoonotic disease that primarily affects the reticuloendothelial system. But, the extent of liver damage in due course of the disease is unclear. This study included 325 brucellosis patients with significant hepatobiliary involvement identified with microbiological analyses from 30 centers between 2000 and 2013. The patients with ≥5 times of the upper limit of normal for aminotransferases, total bilirubin level ≥2 mg/dl or local liver lesions were enrolled. Clinical hepatitis was detected in 284 patients (87.3 %) and cholestasis was detected in 215 (66.1 %) patients. Fatigue (91 %), fever (86 %), sweating (83 %), arthralgia (79 %), and lack of appetite (79 %) were the major symptoms. Laboratory tests showed anemia in 169 (52 %), thrombocytopenia in 117 (36 %), leukopenia in 81 (25 %), pancytopenia in 42 (13 %), and leukocytosis in 20 (6 %) patients. The most commonly used antibiotic combinations were doxycycline plus an aminoglycoside (n = 73), doxycycline plus rifampicin (n = 71), doxycycline plus rifampicin and an aminoglycoside (n = 27). The duration of ALT normalization differed significantly in three treatment groups (p < 0.001). The use of doxycycline and an aminoglycoside in clinical hepatitis showed better results compared to doxycycline and rifampicin or rifampicin, aminoglycoside, doxycycline regimens (p < 0.05). However, the length of hospital stay did not differ significantly between these three combinations (p > 0.05). During the follow-up, treatment failure occurred in four patients (1 %) and relapse was seen in three patients (0.9 %). Mortality was not observed. Hepatobiliary involvement in brucellosis has a benign course with suitable antibiotics and the use of doxycycline and an aminoglycoside regimen seems a better strategy in select patients.

Hemoperitoneum and acute abdomen caused by the rupture of ovarian granulosa cell tumor: a case report.

Granulosa cell tumors (GCT) constitute 70% of all ovarian sex-cord stromal tumors, which account for less than five percent of all ovarian carcinoma. The authors herein report a rare case of a ruptured GCT of the ovary in a 43-year-old female who was admitted to the emergency department with signs of acute abdomen.

Acute hemorrhage related to spontaneous rupture of an uterine fibroid: a rare case report.

The authors present smooth muscle tumors of uncertain malignant potential (STUMP) diagnosis and surgical management of a spontaneously-ruptured degenerated uterine fibroids. A 48-year-old nulliparous presented with a two-day history of abdominal pain, bloating, constipation, and menorrhagia. Within eight hours, her distress level increased. Computed tomography (CT) scanning of the abdomen showed a large, 31 x 25 cm solid-cystic lesion. An emergency laparotomy was indicated. Surgery revealed approximately 2,000 cc of blood and a 30 cm degenerated uterine fibroid with a fundal rupture, cystic, and solid components extending to the lower pole of the liver. Pathology results noted mild nuclear atypia, six mitoses per ten high-power fields (hpf) and necrosis spread that was not coagulative with a STUMP diagnosis. STUMP presents a problematic group of uterine smooth muscle tumors for any clinician. In addition, STUMP can rarely cause acute complications like a rupture. Therefore, prompt diagnosis and effective management are important.

A rare case of lymphangiomyomatosis treated with leuprolide acetate: five-years follow-up.

Lymphangiomyomatosis (LAM) is a rare and systemic disease that is characterized by the abnormal proliferation of smooth muscle-like cells in the lungs and along the axial lymphatic system. The authors herein present a rare case of LAM that was treated with long-term use of leuprolide acetate, a gonadotropin-releasing hormone analogue (GnRHa).

How often do we face side effects of sirolimus in pediatric renal transplantation?

We analyzed 25 pediatric renal transplantation patients on sirolimus (SRL) therapy to assess changes in serum creatinine, glomerular filtration rate, electrolytes, triglycerides, cholesterol, and side effects. Mean time to initiate SRL therapy was 3.2 years. The serum creatinine levels of patients on SRL treatment at 1, 6, 12, and 24 months were 1.67 ± 1.15 mg/dL, 1.18 ± 0.52 mg/dL, 1.24 ± 0.32 mg/dL, 1.15 ± 0.31 mg/dL, and 1.17 ± 0.12 mg/dL, respectively. We observed proteinuria in 3, hyperlipidemia in 5, and anemia in 2 patients, but none had the treatment discontinued. We diagnosed interstitial pneumonia in (n = 1), nasal acneiform lesions (n = 1), and lower extremity edema (n = 1). Hypokalemia developed in 1 subject with high blood SRL levels. In the follow-up period there was no case of acute rejection episode during SRL therapy.

The efficacy of minocycline against methotrexate-induced pulmonary fibrosis in mice.

OBJECTIVES: In addition to its antimicrobial effects, inhibitory effects of minocycline have been demonstrated, including against inflammation, apoptosis, proteolysis, angiogenesis, and tumor metastasis. In this study, we aimed to determine the beneficial effects of minocycline on lung histology and its antioxidant activity in a murine model of pulmonary fibrosis. MATERIALS AND METHODS: Twenty-eight Swiss albino mice were randomly allocated into four groups of seven animals per group. Group I (control group) received intraperitoneal injection of saline. Group II (methotrexate group) received methotrexate orally 3 mg/kg for 28 days. Group III (minocycline group) received methotrexate orally 3 mg/kg and 15 mg/kg of intraperitoneally injected minocycline for 28 days. Group IV (minocycline group) received 15 mg/kg of intraperitoneally injected minocycline for 28 days. Twenty-eight days later, the animals were euthanized. Thereafter, lung tissue samples were harvested. Histological findings of airways were evaluated by light microscopy. The levels of malondialdehyde (MDA), the product of reactive oxygen in lung tissue, and catalase, an antioxidant enzyme, were also determined. RESULTS: In the light microscopic examination, the lung tissues of the control group showed normal histological features. In the methotrexate group, the degree of lung damage (grade 3 fibrosis) was higher than the control and other groups (p: 0.001). In the minocycline-treated group, improvement in lung tissue was noted (median fibrosis score: 3 (MTX group) vs 1 (MTX plus minocycline group); p: 0.001). Only the minocycline group showed normal histological features. Although minocycline reduced the MDA levels in lung tissue, an increase in catalase activity was detected (p: 0.018 and p: 0.014, respectively). CONCLUSIONS: The administration of minocycline may be effective in MTX-induced lung fibrosis in mice. However, further studies with high-dose and long-term treatments are needed.

Outcome of the using older donors for kidney transplantation;Gazi University, Ankara experience.

The extreme organ shortage in Turkey has led to expansion of living and diseased donors. We retrospectively analyzed patient data to determine the outcomes of elderly donors. Among 210 donors, 28 (13.3%) were atleast ≥55 years old. In this group, 17 were from living and 11 from diseased donors. Mean cold ischemia time was 68 ± 21 minutes. The immunosuppressive protocol consisted of induction therapy (simulect 20 mg on days 0 and 4) and immunosuppression with calcineurin inhibitors, mycophenolic acid, and steroids. Nine patients (32.6%) with delayed graft function (DGF) required transient hemodialysis. None of the recipients or their grafts were lost due to surgical complications. We noted 5 acute rejection episodes which were all reversed by pulse steroids. Mean creatinine levels at 1, 3, and 5 years were 1.7, 2.1 and 2.3 mg/dL respectively. Patient and graft survivals at 1, 3, and 5 years were 100%, 96%, and 92% and 100%, 92%, and 92%, respectively. Although 3.6% of recipients displayed DGF, it did not affect graft outcomes. In conclusion, kidney transplantation from older donors should be considered to be an option for kidney transplantation.

Protective effect of resveratrol, a red wine constituent polyphenol, on rats subjected to portal vein thrombosis.

This experimental study investigated the prophylactic effects of the antioxidant and antiaggregant compound resveratrol (R) on portal vein thrombosis (PVT) in rats. Thirty rats weighing 200- 250 g were distributed in 3 groups: Group A (n = 10) and underwent PVT+R, Group B (n = 10) PVT alone, and Group C (n = 10) were subjected to a sham operation. Group A rats received R (60 mg/d per naso-gastric tube) for 10 days before PVT. Concerning antioxidant status, statistically significant increases in both tissue and plasma levels of reduced glutathione (GSH) and decrease in malondialdehyde (MDA) levels were observed in the PVT+R group compared with the PVT group (P < .001 for all). Comparison of these parameters with those of the sham group revealed significantly higher tissue and plasma levels of GSH and low MDA levels among the sham-operated group when compared with to the PVT+R or PVT groups (P < .001 for all). Concerning the antiaggregant status, significant increases of c-AMP levels were detected in rats treated with R before experiencing PVT (P < .001). Cyclic AMP levels in the sham group were significantly higher than those of either the PVT or PVT+R groups (P < .001). One may advise patients undergoing liver transplantation and carrying certain cardiovascular disease risk factors to ingest foods containing R to minimize PVT.

Successful solid organ transplantation from septicemic cadaveric donors: case report.

Systemic donor infections especially with gram-negative organisms are regarded as an absolute contraindication to cadaveric organ donation for transplantation. This is largely due to fear of transmitting the pathogenic organisms to the immunosuppressed recipient. However, due to the current shortage of organs available for transplantation, clinicians are faced with the option to use organs from infected donors. Between 1996 to January 2006, we collected 44 solid organs. Two out of nine donors had microorganisms from blood cultured. Case 1 was of 23-year old woman whose cause of brain death was intracerebral bleeding due to a traffic accident. The donor had stayed 9 days in the intensive care unit prior to brain death. Two kidneys, two livers (split), and or heart were used. Klebsiella was the organism on blood culture. Case 2 was of 35-year-old man; cause of brain death was cerebral hematoma due to traffic accident. The donor had stayed 6 days prior to brain death onset. The liver and two kidneys were used. Acinetobacter baumannii was yielded upon blood culture. All donors were treated with appropriate antibiotics for at least 48 hours prior to organ procurement with consequent negative blood cultures, while the recipients received the same culture-specific antibiotics for 10 days following transplantation. One donor (case 1) heart and both donor corneas were not used due to infection. All patients are alive with excellent graft function at a median of 90 days following transplantation. In conclusion, our results suggested that bacteremic donors with severe sepsis under proper treatment can be considered for transplantation.

Renal transplantation in children.

INTRODUCTION: Various immunological, metabolic, and technical factors render pediatric recipients with end-stage renal disease unique from their adult counterparts. In addition, the potential for complications after renal transplantation is far greater in children than in adults. In this study, we retrospectively analyzed 83 pediatric recipients who underwent kidney transplantation at our institution from 1975 to 2004. MATERIALS AND METHODS: From November 1975 to December 2004, 1523 renal transplantations were performed at our institution with 56 procedures in 83 pediatric patients (44 boys and 39 girls; age range, 7 to 17 years; mean age, 14.9 +/- 2.2 years). RESULTS: Long-term follow-up revealed the following morbidities in 14 (16.3%) recipients: lymphocele in 7 (8.1%) patients, perirenal hematoma in 2 (2.3%), graft renal artery stenosis in 2 (2.3%), ureteral stenosis in 2 (2.3%), and ureteral anastomotic leak in 1 (1.2%). Six (7.2%) recipients with a functioning graft died during follow-up (five deaths were infection related, and the cause of one death was unknown). Five grafts failed (four for immunological reasons and one as a result of recurrent disease). The 1-, 3-, 5-year patient and graft survival rates were 98%, 93%, 92% and 91%, 78%, 67% for living related transplantations versus 98%, 91%, 90% and 92%, 76%, 65% for cadaveric transplantations, respectively. DISCUSSION: Better outcomes for renal transplantation in children may be obtained by strict adherence to precise surgical techniques, better immunosuppressive management, and early diagnosis/effective treatment of complications.

A corner-saving ureteral reimplantation technique without stenting.

In this study we present our new technique, which will simplify reconstruction of even a small-caliber ureter. Our transplantation team has performed 1523 renal transplantation since 1975. From 1975 to 1983, we performed 300 ureteroneocystostomies using the modified Politano-Leadbetter technique. Since 1983, the extravesical Lich-Gregoir technique was used in combination with temporary ureteral stenting in 1141 patients. After September 2003, we began a corner-saving technique. Eighty-two (62 living related, 20 cadaver) renal transplantations have been performed since September 2003. The mean recipient age was 32.2 +/- 10.9 years (range, 7 to 63). Mean donor age was 38.9 +/- 13.1 years. For ureteral reimplantation, a running suture is started from 3 mm ahead from the middle of the posterior wall and finished 3 mm afterward. After the last stitch, both ends of the suture material are pulled and the posterior wall of the ureter and bladder are approximated tightly. The anterior wall is sewn either with the same suture or another running suture. Since using this technique, we have not employed a double J or any other stent to prevent ureteral complications at the anastomosis side. We have seen only two (2.4%) ureteral complications. In conclusion, due to the low complication rate, we believe that our new technique is the safest way to perform a ureteroneocyctostomy.

Expanded criteria for liver transplantation in patients with hepatocellular carcinoma.

INTRODUCTION: Liver transplantation is the only curative treatment for patients with cirrhosis and unresectable hepatocellular carcinoma (HCC) without extrahepatic dissemination. Since criteria for transplantation in HCC are controversial, we evaluated our early results of liver transplantation for unresectable HCC. MATERIALS AND METHODS: Three women and 14 men (age range, 1.1 to 64 years) with preoperatively diagnosed or incidentally discovered HCC underwent liver transplantation. Six grafts were obtained from cadaveric donors, and each of the remaining 11 grafts from a living related donor. Criteria for participation, independent of tumor size and number of tumor nodules, were no invasion of major vascular structure and no evidence of extrahepatic disease. In nine patients, tumors were beyond the Milan criteria. Twelve patients (86.7%) received tacrolimus and 2 (13.30%), rapamycin monotherapy with early withdrawal of corticosteroid therapy. Two patients underwent neoadjuvant chemoembolization before transplantation; none received adjuvant chemotherapy. Seven patients with hepatitis B virus infection underwent antiviral prophylaxis with antibody to hepatitis B surface antigens and lamivudine. RESULTS: During follow-up (range, 1 to 17 months), all patients exhibited excellent graft function. Imaging studies revealed no evidence of tumor recurrence and no elevation of alpha fetoprotein or carcinoembryonic antigen levels. DISCUSSION: Low-dose immunosuppressive therapy and expanded criteria for liver transplantation in patients with HCC, especially when donation from a living related donor is possible, appear to inhibit disease recurrence and improve outcomes.

Venous complications after orthotopic liver transplantation.

We report venous complications, including portal vein and hepatic vein stenoses, that required interventional radiological treatment in three pediatric and two adult living related liver transplant recipients. Between April 2001 and April 2005, 81 liver transplantations were performed at our hospital. Sixty-two grafts were from living donors. During follow-up, three portal vein stenoses were identified in three pediatric recipients, and two hepatic vein stenoses in two adult patients. In the children, two had received left lateral segment grafts, and one had received a right lobe graft from two mothers and one father, respectively. The etiologies of liver failure were Alagille syndrome, biliary atresia, and fulminant Wilson's disease. Portal vein stenoses were identified at 8, 11, and 12 months after transplantation; all three patients underwent percutaneous transhepatic portal venous angioplasty with a success rate of 100%. The mean follow-up was 102 days; no recurrence has occurred. In contrast, hepatic venous stenoses were diagnosed in two adult recipients. One of them was a 24-year-old woman with autoimmune hepatitis and the other a 43-year-old man with cryptogenic cirrhosis. Hepatic vein stenoses were diagnosed at 3 and 4 months after transplantation. Both hepatic vein stenoses were dilated with balloon angioplasties via the transjugular route. Venous complications identified by Doppler ultrasonography were confirmed by computerized tomographic angiography. Angioplasty represents an effective and safe alternative to reconstructive surgery in the treatment of venous complications after liver transplantation.

The effect of graft nephrectomy on long-term graft function and survival in kidney retransplantation.

We retrospectively evaluated the long-term results of 53 (3.5%) recipients who received second allograft among 1486 kidney transplants between November 3, 1975 and June 30, 2004. Two study groups were patients in Group 1 (n = 21) who underwent allograft nephrectomy and those in Group 2 (n = 32) who did not. We assessed demographic features, rejection rates throughout the follow-up period, and serum creatinine levels at 12 months as well as graft and patient survival rates, postoperative complications, time interval between transplantations, and HLA matches. Forty-three patients who underwent retransplantation received kidneys from living-related donors and the remaining 10 from cadaveric donors. Mean serum creatinine levels of Group 1 versus Group 2 were 1.8 mg/dL (range, 0.8 to 6.6 mg/dL) versus 2.1 +/- 1.1 mg/dL (range, 1.1 to 7.1 mg/dL). HLA-AB and HLA-DR mismatches were 1.9 +/- 1.1 versus 1 +/- 0.6, respectively (P = .01). Acute rejection rates were not significantly different between Groups 1 (9/21, 43%) and 2 (12/32, 38%) (P < .05). The average intervals between the first and the second transplantations were 62 +/- 26 months in Group 1 (P = .02) and 32 +/- 11 months in Group 2. One-, 3-, and 5-year graft survival rates in Group 1 versus Group 2 were 83% versus 89% (P > .05); 64% versus 79% (P > .05), and 45% versus 68% (P = .04), respectively. In conclusion, we did not observe any advantage of graft nephrectomy before retransplantation. The length of the interval between the first and the second transplantations may have a negative correlation with second graft survival.

Living-related liver transplantation in pediatric patients.

INTRODUCTION: Many developments in surgical technique, immunosuppression, and patient selection criteria have led to improved long-term patient and graft survival in pediatric patients receiving liver transplants. In this study, we examined the early results of 26 pediatric recipients who underwent 26 liver transplantations between January 2003 and December 2004 at our institution. MATERIALS AND METHODS: The most common indications for liver transplantation were cholestasis in 10 patients (38.5%) and Wilson's disease in 8 (30.8%). Other indications were fulminant hepatic failure (4 patients, 15.4%), tyrosinemia (2 patients, 7.7%), Caroli disease (1 patient, 3.8%), and cryptogenic cirrhosis (1 patient, 3.8%). One recipient with Byler disease and two with tyrosinemia also had incidental hepatocellular carcinoma. RESULTS: Of 26 patients, 24 (92.3%) underwent living-related liver transplantation and 2 (7.7%) underwent cadaveric transplantation. The medical records of all patients were retrospectively reviewed. Twenty-two of 26 survived with excellent graft function, showing 91.2%, 86.4%, and 81.6% at 3, 12, and 24 months graft and patient survival rates, respectively. Sixteen patients (61.5%) developed various morbidities with biliary and vascular complications being the most common. Four patients (15.3%) developed bile leaks. Four patients (15.3%) developed hepatic artery thromboses. Five patients (19.2%) developed life-threatening infections. Four patients (15.4%) died during the study period, three owing to infectious complications. The other patient died due to acute respiratory distress syndrome. CONCLUSION: Despite technical difficulties and a donor organ shortage, the results of liver transplantation in pediatric patients with end-stage liver disease have demonstrated promising results at our institution.
