In this retrospective study of hepatitis C virus (HCV)-infected transplant recipients in the 9-center Adult to Adult Living Donor Liver Transplantation Cohort Study, graft and patient survival and the development of advanced fibrosis were compared among 181 living donor liver transplant (LDLT) recipients and 94 deceased donor liver transplant (DDLT) recipients. Overall 3-year graft and patient survival were 68% and 74% in LDLT, and 80% and 82% in DDLT, respectively. Graft survival, but not patient survival, was significantly lower for LDLT compared to DDLT (P = 0.04 and P = 0.20, respectively). Further analyses demonstrated lower graft and patient survival among the first 20 LDLT cases at each center (LDLT 20; P = 0.002 and P = 0.002, respectively) and DDLT recipients (P < 0.001 and P = 0.008, respectively). Graft and patient survival in LDLT >20 and DDLT were not significantly different (P = 0.66 and P = 0.74, respectively). Overall, 3-year graft survival for DDLT, LDLT >20, and LDLT 20 were not significantly different. Important predictors of graft loss in HCV-infected patients were limited LDLT experience, pretransplant HCC, and higher MELD at transplantation. 相似文献

This prospective study was designed to identify the role of postnatal penicillin prophylaxis in the prevention of neonatal group B streptococcus (GBS) infection. We studied 10 998 infants. Of these, 5389 were in the penicillin prophylaxis group (PP) and 5609 infants did not receive penicillin prophylaxis (NPP). Infants were allocated to treatment by month of birth, alternating 3-mo blocks or 2-mo blocks to the two groups after the first block was randomly assigned. The use of PP reduced the incidence of clinical sepsis (1.7% PP versus 2.5% NPP, p < 0.01), GBS infection (0.4% PP versus 0.9% NPP, p < 0.001) and deaths from sepsis (0.1% PP versus 0.3% NPP, p < 0.05). We conclude that the routine use of postnatal penicillin prophylaxis appears to be effective in reducing the incidence of clinical sepsis and death from sepsis in neonates. 相似文献

We report a case of Klippel-Trenaunay-Weber syndrome presenting prenatally as a massive congenital lymphangiohemangioma of the thigh. Routine ultrasonographic examination revealed multiple distorted cystic areas extending from the right flank through the right lower extremity of a 30-week fetus. A diagnosis of cystic lymphangioma of the thigh was suspected prenatally. Neonatal evaluation confirmed the prenatal findings. Neonatal color Doppler imaging revealed blood vessels within the tumor. The differential diagnosis is discussed together with available therapeutic procedures. 相似文献

Nephrogenic systemic fibrosis (NSF) is a debilitating disorder seen in-patient with advanced chronic kidney disease (CKD). Recent evidence suggests a link between NSF and the administration of gadolinium-based contrast agents (Gd-CA). In addition, other risk factors have also been suggested to facilitate the development of NSF in this population after Gd-CA. These include metabolic acidosis, high-dose erythropoietin therapy, and the altered mineral metabolism of CKD. While it is possible that these factors may increase the risk of NSF after Gd-CA exposure, they may also simply reflect conditions that increase the risk of getting exposed to Gd-CA, particularly at high doses. Furthermore, given the risk of NSF in CKD, physicians must weigh the risks of NSF versus the risk of contrast-induced nephropathy (CIN) with iodinated agents in this population. In this review, we will provide a nephrologist's perspective on these issues and the nephrologist's role in the prevention of NSF. 相似文献

Summary. Homeless adults are at high risk for hepatitis B virus (HBV) infection. In addition to culturally sensitive programmes designed to enhance vaccination compliance, accelerated HBV vaccination (three doses over 21 days) have also been suggested to improve compliance among high-risk groups. In this paper, we examined predictors of completers of two of three doses of a HAV/HBV vaccine series, normally delivered over a 6-month period, to simulate compliance with an accelerated series, dosed over 4 weeks. A convenience sample of 865 homeless adults was randomized into a nurse case-managed approach (NCMIT) vs standard programmes with (SIT) and without tracking (SI). Each group was assessed for completion of two of the three dose HAV/HBV vaccine series as well as the full three dose vaccine series. Sixty-eight percent of the NCMIT participants completed the three dose vaccination series at 6 months compared to 61% of SIT participants and 54% of SI participants. Eighty-one percent of the NCMIT participants completed two of the vaccinations compared to 78% of SIT participants and 73% of SI participants. The NCMIT approach resulted in greater numbers of completers of two of three doses and of the full three dose vaccine series. Predictors of completers of two doses and the full three dose vaccine series are provided. A greater number of homeless persons completed two doses across the three groups compared to the three dose vaccine series. The use of nurse case-management and tracking, coupled with an accelerated HAV/HBV vaccination schedule, may optimize vaccination compliance in homeless adults. 相似文献

Hepatitis C is the leading cause of liver-related US morbidity and mortality. The ultimate goal of therapy is to prevent disease
complications and improve life expectancy. Effective antiviral therapy uses pegylated interferon and ribavirin. Certain populations
pose a significant challenge to treatment success. The likelihood of achieving sustained virologic response rates depends
on host, viral, and treatment factors, with genotype the strongest predictor. The greatest impact in optimizing drug exposure
can result from targeting modifiable factors and, in some instances, from extending treatment duration or increasing standard
treatment doses. Adherence to treatment duration and administration is crucial in obtaining optimal sustained virologic responses.
Accurately assessing which patients may be hard to treat is of utmost importance because it facilitates setting realistic
goals with the patient, which may prompt a more aggressive and multidisciplinary approach to treating these individuals. 相似文献
