ABSTRACT

Babesiosis is an emerging infection in the state of Pennsylvania, and clinicians need to be made aware of its clinical manifestations as well as the risk factors associated with severe disease. Before 2010, our tertiary academic center in central Pennsylvania previously saw zero cases of babesiosis. We saw our first confirmed case of Babesia infection acquired in Pennsylvania in 2011; we recorded 2 confirmed cases in 2017 and 4 confirmed cases in 2018. All 4 cases from 2018 were thought to be acquired in southcentral Pennsylvania counties, whereas prior reports of cases were predominately in the southeast and northeast counties of the state.

ABSTRACT

OBJECTIVES: In multiple countries, endovascular/disseminated Mycobacterium chimaera infections have occurred in post-cardiac surgery patients in association with contaminated, widely-distributed cardiac bypass heater-cooler devices. To contribute to long-term characterization of this recently recognized infection, we describe the clinical course of 28 patients with 3-7 years of follow-up for survivors. METHODS: Identified at five hospitals in the United States 2010-2016, post-cardiac surgery patients in the cohort had growth of Mycobacterium avium complex (MAC)/M. chimaera from a sterile site or surgical wound, or a clinically compatible febrile illness with granulomatous inflammation on biopsy. Case follow-up was conducted in May 2019. RESULTS: Of 28 patients, infection appeared to be localized to the sternum in four patients. Among 18 with endovascular/disseminated infection who received combination anti-mycobacterial treatment and had sufficient follow-up, 39% appeared to have controlled infection (>12 months), 56% died, and one patient is alive with relapsed bacteremia. While the number of patients is small and interpretation is limited, four (67%) of six patients who had cardiac prosthesis removal/replacement appeared to have controlled infection compared to three (25%) of 12 with retained cardiac prosthesis (p >0.14; Fisher's exact test). CONCLUSIONS: Given poor response to treatment and potential for delayed relapses, post-cardiac surgery M. chimaera infection warrants aggressive treatment and long-term monitoring.

ABSTRACT

We conducted a case-control study to examine the association between outpatient infectious disease (ID) follow-up and risk of 30-day readmission in 384 patients receiving outpatient parenteral antimicrobial therapy. ID outpatient follow-up within 2 weeks was associated with lower risk of all-cause 30-day readmission (adjusted odds ratio, 0.33; P = .0001).

ABSTRACT

Sepsis mortality may be improved by early recognition and appropriate treatment based on evidence-based guidelines. An intervention was developed that focused on earlier identification of sepsis, early antimicrobial administration, and an educational program that was disseminated throughout all hospital units and services. There were 1331 patients with sepsis during the intervention period and 1401 patients with sepsis during the control period. After controlling for expected mortality, patients in the intervention period had 30% lower odds of dying (odds ratio = 0.70, 95% confidence interval [CI] = 0.57 to 0.84). They also had 1.07 fewer days on average in the intensive care unit (95% CI = -1.98 to -0.16), 2.15 fewer hospital days (95% CI = -3.45 to -0.86), and incurred on average $1949 less in hospital costs, although the effect on costs was not statistically significant. Continued incremental improvement and sustainment is anticipated through organizational oversight, continued education, and initiation of an automated electronic sepsis alert function.

ABSTRACT

CONTEXT: People living with human immunodeficiency virus (HIV)/AIDS (PLWHA) who continue high-risk behaviors may represent an important source for transmitting HIV infections. OBJECTIVE: To identify factors associated with high-risk behaviors among PLWHA and to plan better HIV prevention intervention strategies in HIV care. DESIGN: A cross-sectional survey to assess HIV transmission risk behaviors including sexual practices, disclosure of HIV infection status to sexual partner(s), and injection drug use. SETTING: Five HIV outpatient clinics serving diverse PLWHA in south central Pennsylvania. PARTICIPANTS: A total of 519 HIV-infected patients. MAIN OUTCOME MEASURES: Two high-risk behaviors that may increase HIV transmission risk: (1) any unsafe sexual behavior and (2) nondisclosure of HIV infection status to sexual partner(s). An unsafe sexual behavior was defined as inconsistent condom use, sex under the influence of alcohol or drugs, or exchange of sex for money. A subgroup analysis was performed to examine factors related to unprotected anal intercourse among sexually active men who have sex with men. RESULTS: About two-thirds of 519 HIV patients (65.7%) were sexually active, and nearly 50% of sexually active patients reported at least 1 unsafe sexual behavior. Nondisclosure of HIV infection status was reported by about 15% of the patients. Partners' characteristics including HIV infection status and the perceived partner behavior (ie, partner may have sex with other people) were significantly associated with unsafe sexual behaviors and with nondisclosure of HIV infection status. Non-Hispanic black males were more likely to withhold their HIV infection status from their sexual partner(s) (adjusted odds ratio = 4.51) than their white counterparts. In addition, the perceived partner sexual behavior was significantly related to unprotected anal intercourse among men who have sex with men (adjusted odds ratio = 2.00). CONCLUSIONS: High-risk sexual behaviors are commonly reported by PLWHA, and these behaviors may be influenced by their partners' characteristics. HIV prevention interventions and public health strategies need to be incorporated into HIV care.

ABSTRACT

INTRODUCTION: Histoplasmosis is an endemic mycosis with most cases of clinical illness reported in North and Central America. Rarely, patients develop progressive disseminated histoplasmosis with extrapulmonary manifestations. These infections are fatal if not appropriately treated. CASE PRESENTATION: We report a case of progressive disseminated histoplasmosis presenting with fever, progressive dyspnea, and pancytopenia in a 51-year-old Caucasian man who had been treated with chronic steroids for a diagnosis of sarcoidosis made 20 years previously. His presentation was initially mistaken for sarcoidosis but, fortunately, laboratory results showed hematologic abnormalities, and the diagnosis of histoplasmosis was made by bone marrow biopsy. CONCLUSIONS: Sarcoidosis reduces T cell activity, and the addition of steroids for treatment causes further immunosuppression and vulnerability for development of a disseminated infection. The diagnosis of histoplasmosis depends mainly on clinical presentation and host factors. Although there are diagnostic laboratory tests available, clinicians may need to diagnose histoplasmosis by history and physical examination alone and treat empirically, since awaiting Histoplasma-specific laboratory results would delay initiation of treatment. Primary care providers, hospitalists, and subspecialists alike should be aware of the overlap in clinical and radiological presentations of sarcoidosis and histoplasmosis, and when and how to pursue diagnostic testing for endemic mycoses, since these infections can be fatal in immunosuppressed patients without appropriate treatment.

ABSTRACT

OBJECTIVE: Syphilis incidence has been steadily increasing among HIV-infected men in the United States, representing an important public health challenge to HIV prevention. Clinic-based HIV prevention interventions are available but may need to be revisited in response to syphilis epidemic. We wanted to better understand the current epidemiology of syphilis in rural HIV-infected men who routinely received HIV risk-reduction counseling in order to plan more effective HIV prevention strategies in clinical care. METHODS: We conducted a retrospective cohort study to examine factors associated with syphilis infections in rural HIV-infected men who received sexually transmitted disease screening and HIV risk-reduction counseling during HIV primary care from January 2008 to June 2013. We assessed patients' demographic, clinical, behavioral and psychosocial characteristics and performed a multivariable exact logistic regression to identify factors related to syphilis. RESULTS: Despite routine risk screening and HIV risk-reduction counseling, a total of 51 syphilis infections were diagnosed among 702 HIV-infected men (5 patients were diagnosed ≥ 2 episodes). The majority of the study participants was sexually active and reported at least one unsafe sexual behavior, mainly inconsistent condom use. Younger age (<35 years, adjusted odds ratio (aOR)=3.09), higher educational attainment (some college or above, aOR=3.72), and perception that the partner may have sex with other people (aOR=3.10) were significantly associated with syphilis infection. Non-injection drug use was related to syphilis in HIV-infected men who have sex with men (aOR=2.86). DISCUSSION: Some HIV-infected men, especially young, educated men, or those who perceived that their partners may have sex with other people, continue to have high-risk behaviors that increase their own risks of acquiring syphilis and may also facilitate HIV transmission. New strategies need to be developed for HIV primary care providers to help HIV-infected patients maintain safer sex practices.
