RESUMO
Approximately 50% of human immunodeficiency virus (HIV)-infected adolescents fail to achieve complete viral suppression, largely due to nonadherence to their antiretroviral drug regimens. Numerous personal, financial, and societal barriers contribute to nonadherence, which may lead to the development of HIV drug resistance. Long-acting antiretroviral drugs hold the promise of improved adherence because they remove the need for swallowing one or more pills daily. Cabotegravir (an integrase strand transfer inhibitor) and rilpivirine (a non-nucleoside reverse transcriptase inhibitor) can now be intramuscularly co-administered to HIV-infected adolescents every 4-8 weeks if they are virologically suppressed and without resistance mutations to cabotegravir or rilpivirine. Adverse effects are few and non-severe. Widespread use of this complete antiretroviral therapy may be limited by drug costs, need for sites and skilled personnel who can administer the injections, and ethical challenges. Other long-acting medications and new antiretroviral therapy delivery systems are under active investigation and show great promise.

BACKGROUND: Clostridium difficile infection (CDI) is one of the most common nosocomial infections in the United States, with an increasing incidence in children. Approximately 20% of pediatric patients develop recurrent infections. It's imperative to further analyze the incidence of recurrent CDI in the pediatric population and determine the most effective treatments. The primary goal of this study is to characterize children with recurrent CDI at our institution, including both hospital-acquired CDI (HA-CDI) and community-acquired CDI (CA-CDI) cases, summarize the various treatments utilized, including fecal microbiota transplant (FMT) and compare their success rates. METHODS: A retrospective cohort study of pediatric patients 1-21 years of age treated for CDI at a single institution from January 2010 to December 2014 was performed. RESULTS: There were 175 subjects with 215 separate episodes of CDI. Oral metronidazole was the most common initial treatment (145/207, 70%) followed by oral vancomycin (30/207, 15%), with recurrence rates of 30% (42/145) and 37% (11/30), respectively. Twenty-nine percent (63/215) of all initial CDI cases had at least 1 documented recurrence. Using multivariate analysis, subjects with HA-CDI were 2.6 times less likely to recur than those with CA-CDI (odds ratio: 0.39; 95% confidence interval: 0.18-0.85; P = 0.018). The overall success rate for FMT at our institution was 10/12 (83%). CONCLUSIONS: Our data show that cases of HA-CDI were less likely to recur compared with CA-CDI. Although currently reserved for multiply-recurrent cases, FMT was highly successful in our small cohort. More studies on FMT should be conducted to further evaluate its usefulness in the treatment of recurrent CDI in children.

Salmonella enterica serotype Panama accounts for <1% of all reported cases of Salmonellosis. Previous reports suggest that it may be unusually virulent in children. We report the case of a family, five of six of whom developed a diarrheal illness due to this organism following exposure during a trip to Costa Rica. Included among these patients were three children, all of whom developed clinical shock requiring aggressive fluid resuscitation, and all of whom ultimately recovered. DNA fingerprinting, using pulsed-field gel electrophoresis, demonstrated that all three children were infected with an identical strain of Salmonella. Moreover, this strain was unique among strains recovered in Nebraska. Clinicians should be aware of the propensity of Salmonella enterica serotype Panama to cause especially severe disease in children; laboratory personnel should be aware of the unique need for thiourea buffering when attempting to perform pulsed-field gel electrophoresis analysis on such strains.
