Strongyloidiasis has been estimated to affect over 600 million people worldwide. It is caused by Strongyloides stercoralis , a roundworm endemic to the tropics and subtropics, especially areas where sanitation is suboptimal Autochthonous transmission has been documented in rural areas of the USA and Europe. Humans are infected when larvae penetrate the skin or are ingested. Autoinfection, in which larvae generated in the host go on to re-infect the host, leads to a state of chronic asymptomatic infection often with eosinophilia. Hyperinfection syndrome may develop when patients develop immune suppression, due to medications such as corticosteroids or following solid-organ transplantation. Hyperinfection is characterized by exponential increase in parasitic burden, leading to tissue invasion and life-threatening disease and associated bloodstream infections due to enteric organisms. Cases following use of corticosteroids for COVID-19 pneumonia have been described. Strongyloidiasis can be diagnosed by direct visualization of larvae in stool or other body fluids, or by serology. Ivermectin is highly effective in treating the disease. Patients with exposure to endemic areas and those expected to become immune suppressed should be screened and treated before starting immune suppressive agents. Empiric treatment should be considered when timely testing is not readily available.
ObjectiveA rise in incidence of STIs has been noted in the USA and in the District of Columbia (DC). We aim to describe changes in incident STIs among persons in care for HIV in Washington, DC as well as trends in HIV viral load among those with incident STIs.MethodsWe conducted a retrospective DC Cohort analysis (n=7810) measuring STI incidence (syphilis, gonorrhoea and chlamydia) as well as incare viral load (ICVL) and percentage with all viral loads less than the limit of detection (%<LLOD) by year (2012–2016) among those with incident STIs.ResultsFrom 2012 to 2016, the incidence of STIs increased: chlamydia from 2.1 to 3.4 cases/100 person-years (p=0.0006), gonorrhoea from 2.1 to 4.0 (p<0.0001), syphilis from 1.7 to 2.6 (p=0.0042) and any STI episode from 5.3 to 8.8 (p<0.0001). STI incidence rates increased for those aged 18–34 (from 13.2 to 23.2 cases/100 person-years, p<0.0001), cisgender men (from 6.5 to 11.5, p<0.0001), non-Hispanic whites (from 8.6 to 16.1, p=0.0003) and men who have sex with men (from 9.3 to 15.7, p<0.0001). During 2012–2016, the ICVL among those with incident STIs improved from 108 to 19 copies/mL and %<LLOD from 23.6% to 55.1%. However, even in 2016, younger participants, cisgender and transgender women, non-Hispanic blacks and Hispanics had higher ICVLs and lower %<LLOD.ConclusionsRates of incident STIs rose among persons in care for HIV in Washington, DC, with improved but not optimal measures of HIV viral suppression. These findings inform focused interventions towards preventing STI transmission and ending the HIV epidemic.
The field of transplant infectious diseases is rapidly evolving, presenting a challenge for clinical practice and trainee education. Here we describe the construction of transplantid.net, a free online library, crowdsourced and continuously updated for the dual purpose of point-of-care evidence-based management and teaching.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
