Forty-seven patients presenting with primary human immunodeficiency virus (HIV) infection were treated with zidovudine 200 mg 3 times a day, lamivudine 150 mg 2 times a day, and indinavir 800 mg 3 ...times a day for 1 year. From a mean pretreatment viral RNA level of 4.93 log10 copies/mL, the proportions of patients having <500 copies/mL at 24 and 52 weeks were 92.0% and 89.2%, respectively. For the 35 patients with data available at 24 and 52 weeks, the corresponding proportions for the <50 copies/mL analysis were 86.6% and 79.3%, respectively. The change in virus load was −2.19 and −2.41 log10 copies/mL at weeks 8 and 52, respectively. CD4 cell counts increased, from a mean of 546 cells/mm3, by 142 cells/mm3 at week 24 and by 210 cells/mm3 at week 52. Three patients discontinued the study because of drug-related toxicity. Six (12.8%) patients had adverse experiences associated with nephrolithiasis. Combination therapy with zidovudine, lamivudine, and indinavir during primary HIV infection results in a profound and sustained reduction in virus load with concurrent recovery of the CD4 cell population.
Objectives: Neisseria gonorrhoeae infections are the second most commonly reported disease in the United States and cause significant morbidity. We describe the prevalence of gonorrhea in a large ...sample of men tested for gonorrhea and Chlamydia trachomatis in Baltimore, Denver, San Francisco, and Seattle. Methods: Gonorrhea prevalence was measured among 17,712 men tested in a variety of non-sexually transmitted disease (STD) clinic venues using urine-based nucleic acid amplification tests. Results: Among 16,850 asymptomatic men, prevalence ranged from 0% to 1.5% by city (P = 0.20): Baltimore 1.3%, Denver 1.5%, San Francisco 1.5%, and Seattle 0%. Among 862 symptomatic men, the gonorrhea prevalence varied from 0.0% to 28.3% by city (P <0.01). Conclusions: The high prevalence of gonorrhea in symptomatic men supports the importance of testing for symptomatic men. The prevalence of gonorrhea among asymptomatic men is low, and routine screening cannot be recommended when screening is performed for chlamydia, unless a substantial local prevalence of gonorrhea can be documented in specific targeted venues or population groups.
The authors analyze a single center's 11-year experience with 190 orthotopic liver transplants for congenital biliary atresia.
Hepatic portoenterostomy generally is the initial treatment for children ...with congenital biliary atresia. Despite multiple modifications of the hepatic portoenterostomy, two thirds of treated patients still develop recurrent cholestasis, portal hypertension, cholangitis, and cirrhosis. Therefore, the only hope of long-term survival in the majority of children with congenital biliary atresia is definitive correction with orthotopic liver transplantation.
The medical records of 190 consecutive patients undergoing orthotopic liver transplantation for congenital biliary atresia from July 1, 1984 to February 29, 1996 were reviewed. Results were analyzed via Cox multivariate regression analysis to determine the statistical strength of independent associations between pretransplant covariates and patient and graft survival. Actuarial patient and graft survival was determined at 1, 2, and 5 years. The type and incidence of post-transplant complications were determined, as was the quality of long-term graft function. The median follow-up period was 3.21 years.
The liver grafts were comprised on 155 whole-organ, 24 reduced-size, and 11 living donor organs. Median pretransplant values for recipient age, weight, and total bilirubin were 1.4 years, 12.3 kg, and 13.8 mg/dL, respectively. One hundred sixty-four patients (86%) had undergone prior hepatic portoenterostomy. Eighty-seven patients (46%) were United Network for Organ Sharing (UNOS) status 1 or 2 at the time of liver transplantation. The majority (15/24, 62%) of reduced-size graft recipients were UNOS status I at the time of transplantation. One hundred fifty-nine patients (84%) received a single graft, whereas 31 patients required 37 retransplants. The 1, 2, and 5 year actuarial patient survival rates were 83%, 80% and 78% respectively, whereas graft survival rates were 81%, 77%, and 76%, respectively. Cox multivariate regression analysis demonstrated that pretransplant total bilirubin, UNOS status, and graft type significantly predicted patient survival, whereas recipient age, weight, and previous hepatic portoenterostomy did not. Current median follow-up values for total bilirubin and aspartate aminotransferase levels in the 154 surviving patients were 0.5 mg/dL and 34 international units/L, respectively.
Long-term patient survival after orthotopic liver transplantation for congenital biliary atresia is excellent and is independent of recipient age, weight, or previous hepatic portoenterostomy. Optimal results are obtained in this patient population when liver transplantation is performed before marked hyperbilirubinemia, and when possible, using a living-donor graft.
We sought to determine the incidence of subacute (within 24 hours) resumption of isthmus conduction after ablation of atrial flutter and to determine whether early repeat ablation would preclude a ...long-term recurrence of atrial flutter. Follow-up study 24 hours after ablation identified some patients likely to develop a recurrence of atrial flutter because of a subacute resumption of isthmus conduction; however, this approach was not uniformly successful because resumption of isthmus conduction occurred over a continuum extending beyond 24 hours of ablation.
