          Abstract

          We describe a 14-year-old girl, who was 13 y after liver transplantation for biliary atresia with an unremarkable postoperative course. She presented with fever of up to 40°C, extreme fatigue, malaise, anorexia, and occasional vomiting. On physical examination the only finding was splenomegaly. Lab results showed hyperglobulinemia and an elevated sedimentation rate. Liver function tests were normal except for mild elevation of γGTP. Abdominal U/S and CT demonstrated an enlarged spleen with retroperitoneal and mesenteric lymph nodes enlargement. An exhaustive evaluation for infectious causes, autoimmune conditions, and malignancy was negative. A full recovery after 5 months prompted testing for self-limited infectious etiologies. Yersinia enterocolitica infection was diagnosed.

          Yersinia enterocolitica infection in children.

          Yersinia enterocolitica can cause illness ranging from self-limited enteritis to life-threatening systemic infection. The present study was undertaken to review the epidemiology, clinical manifestations, complications and outcome of Y. enterocolitica enteritis in children seen at a large children's hospital. The project consisted of a retrospective chart review of medical and microbiologic records of all children with stool cultures positive for Y. enterocolitica during a 7-year period. The review included 142 patients with Y. enterocolitica enteritis. Patients' ages ranged from 18 days to 12 years, and the majority (85%) were younger than 1 year. Most patients presented during November, December and January. History of exposure to chitterlings (raw pork intestines) at home was elicited in 25 of 30 cases. Y. enterocolitica accounted for 12.6% (142 of 1,120) of all bacterial intestinal pathogens isolated during the study period. Blood cultures were positive in 7(9%) of 78 patients; 6 were younger than 1 year and one 12-year-old had sickle cell disease. Of 132 isolates tested all were susceptible to trimethoprim-sulfamethoxazole, tobramycin and gentamicin; the majority were susceptible to cefotaxime (99%), ceftazidime (89%) and cefuroxime (88%). All bacteremic patients responded to cefotaxime treatment. Follow-up evaluation of 40 ambulatory patients revealed no difference in clinical improvement between those treated with oral trimethoprim-sulfamethoxazole (17 of 23) and those who were not treated (8 of 17) (P = 0.1). Y. enterocolitica is an important cause of enteritis in our young patient population during the winter holidays. Exposure of infants to chitterlings appears to be a risk factor. Infants younger than 3 months are at increased risk for bacteremia. Cefotaxime is effective in the treatment of Y. enterocolitica bacteremia; however, the role of oral antibiotics in the management of enteritis needs further evaluation.

            Long-term outcome after liver transplantation in children.

            Children (defined as under 18 yr of age) account for approximately 12.5% of all liver transplants in the United States. Even though the annual number of liver transplantation procedures remains relatively constant, the population of long-term survivors of liver transplantation has grown. Presently, the population of long-term survivors of liver transplantation is 10-fold greater then the number of transplantations carried out each year. For long-term survivors of liver transplantation, the goal is to maintain graft function and wellness while decreasing the morbidity associated with long-term immunosuppression. The primary diagnosis leading to liver transplantation in children do not recur in the allograft. Consequently, many of the complications of liver transplantation, both early and long term, relate to the need for immunosuppression. Children may be at increased risk to develop significant end-organ damage as a result of increased serum lipid levels, elevated blood pressure, altered glucose metabolism, decreased renal function, cancer, and diminished bone accretion that occur as a result of immunosuppressive therapy or complications of therapy. As survival rates have increased, health care providers have begun to assess health-related quality of life. We will review our current knowledge of long-term outcome following pediatric liver transplantation in children.
