Strokes in Patients With Injection Drug Use and Tricuspid Valve Endocarditis - A Case Series.

Research Design: In this study, we describe patients from a tertiary care safety-net hospital endocarditis registry with tricuspid valve infective endocarditis (TVIE), and concomitant acute or subacute ischemic stroke predominantly associated with injection drug use (IDU). We retrospectively obtained data pertinent to neurologic examinations, history of injection drug use (IDU), blood cultures, transthoracic/transesophageal echocardiography (TTE/TEE), neuroimaging, and Modified Rankin Scale (mRS) scores at discharge. Only those patients with bacteremia, tricuspid valve vegetations, and neuroimaging consistent with acute to subacute ischemic infarction and microhemorrhages in two cases were included in this series. Results: Of 188 patients in the registry, 66 patients had TVIE and 10 of these were complicated by ischemic stroke. Neurologic symptoms were largely non-specific, eight patients had altered mental status and only 3 had focal deficits. Nine cases were associated with IDU. Two patients had evidence of a patent foramen ovale on echocardiography. Blood cultures grew S. aureus species in 9 of the patients, all associated with IDU. Three patients died during hospitalization. The mRS score at discharge for survivors ranged 0-4. Conclusions: Patients with strokes from TVIE had heterogeneous presentations and putative mechanisms. We noted that robust neuroimaging is lacking for patients with TVIE from IDU and that such patients may benefit from neuroimaging as a screen for strokes to assist peri-operative management. Further inquiry is needed to elucidate stroke mechanisms in these patients.

Surgical outcomes of pulmonary valve infective endocarditis: A US population-based analysis.

BACKGROUND: Pulmonary valve infective endocarditis (PVIE) represents a rare subset of right-sided IE. This study aimed to evaluate the population-level surgical outcomes of PVIE in the United States. METHODS: We performed a retrospective observational study using the 2002-2017 National Inpatient Sample database. We included hospitalizations with both IE and PV interventions. We excluded Tetralogy of Fallot, congenital PV malformation, and those who underwent the Ross procedure. The primary outcome was in-hospital mortality. The secondary outcomes included major complications and length of hospital stay. RESULTS: We identified 677 PVIE hospitalizations that underwent surgical treatment, accounting for 0.06% of all IE hospitalizations. The mean age was 35.2 ± 1.7 years; 60.0% were White, 30.3% were women, and 11.4% were intravenous drug users. Most were treated in large-sized (70.1%) urban teaching (88.8%) hospitals. Close to 30% of patients received at least one concomitant valve procedure. The in-hospital mortality was 5.5% for the entire cohort, and the median length of stay was 16 days. Major complications included complete heart block (8.7%), acute kidney injury (8.1%), and stroke (1.3%). The differences in mortality and complications rate comparing PV repair and replacement were not statistically significant. PV repair was associated with a longer length of hospital stay compared to PV replacement (median: 25 vs. 16 days, p = 0.03). CONCLUSIONS: This study defines the population-level in-hospital outcomes after surgical intervention of PVIE. Surgically treated PVIE patients are associated with relatively low mortality and morbidities. The outcomes between PV replacement and repair are similar.

Rethinking Home-based Outpatient Parenteral Antibiotic Therapy for Persons Who Inject Drugs: An Opportunity for Change in the Time of COVID-19.

Outpatient parenteral antibiotic therapy (OPAT) refers to the monitored provision of intravenous antibiotics for complicated infections outside of a hospital setting, typically in a rehabilitation facility, an infusion center, or the home. Home-based OPAT allows for safe completion of prolonged courses of therapy while decreasing costs to the healthcare system, minimizing the risk of hospital-related infectious exposures for patients, and permitting patients to recover in a familiar environment. Amidst the COVID-19 pandemic, during which nursing facilities have been at the center of many outbreaks of the SARS-CoV-2 virus, completion of antimicrobial therapy in the home is an even more appealing option. Persons who inject drugs (PWID) frequently present with infectious complications of their injection drug use which require long courses of parenteral therapy. However, these individuals are frequently excluded from home-based OPAT on the basis of their addiction history. This commentary describes perceived challenges to establishing home-based OPAT for PWID, discusses ways in which this is discriminatory and unsupported by available data, highlights ways in which the COVID-19 pandemic has accentuated inequities in care, and proposes a multidisciplinary approach championed by Addiction specialists to increasing implementation of OPAT for appropriate patients with substance use disorders.

Early administration of interleukin-6 inhibitors for patients with severe COVID-19 disease is associated with decreased intubation, reduced mortality, and increased discharge.

OBJECTIVE: The aim of this observational study was to determine the optimal timing of interleukin-6 receptor inhibitor (IL6ri) administration for coronavirus disease 2019 (COVID-19). METHODS: Patients with COVID-19 were given an IL6ri (sarilumab or tocilizumab) based on iteratively reviewed guidelines. IL6ri were initially reserved for critically ill patients, but after review, treatment was liberalized to patients with lower oxygen requirements. Patients were divided into two groups: those requiring ≤45% fraction of inspired oxygen (FiO2) (termed stage IIB) and those requiring >45% FiO2 (termed stage III) at the time of IL6ri administration. The main outcomes were all-cause mortality, discharge alive from hospital, and extubation. RESULTS: A total of 255 COVID-19 patients were treated with IL6ri (149 stage IIB and 106 stage III). Patients treated in stage IIB had lower mortality than those treated in stage III (adjusted hazard ratio (aHR) 0.24, 95% confidence interval (CI) 0.08-0.74). Overall, 218 (85.5%) patients were discharged alive. Patients treated in stage IIB were more likely to be discharged (aHR 1.43, 95% CI 1.06-1.93) and were less likely to be intubated (aHR 0.43, 95% CI 0.24-0.79). CONCLUSIONS: IL6ri administration prior to >45% FiO2 requirement was associated with improved COVID-19 outcomes. This can guide clinical management pending results from randomized controlled trials.

Neurological Complications of Endocarditis: A Multidisciplinary Review with Focus on Surgical Decision Making.

Infective endocarditis (IE) is a systemic disease with many potential neurologic manifestations including ischemic and hemorrhagic strokes, cerebral microbleeding, infectious intracranial aneurysms, meningitis, brain abscesses, and encephalopathy. The majority of left-sided (heart) IE patients have brain lesions that may alter management decisions, warranting the systematic use of magnetic resonance imaging. Many patients require surgical treatment of valvular disease, and central nervous system lesions weigh into decision making. Data regarding the timing of surgery are conflicting, but earlier surgery appears to be safe in most ischemic strokes, while ideally surgery should be delayed for 3 to 4 weeks in patients with hemorrhagic strokes. IE requires a multidisciplinary team to collaboratively care for the patient. In this article, we review the current understanding and management of the neurological complications of IE and their impact on the performance and timing of cardiac surgery.

Evaluating Quality of Care for Sexually Transmitted Infections in Different Clinical Settings.

BACKGROUND: We examined quality of care across different clinical settings within a large safety-net hospital in Massachusetts for patients presenting with penile discharge/dysuria or vaginal discharge. METHODS: Using a modified Delphi approach, a list of sex-specific sexually transmitted infection (STI) quality measures, covering 7 domains of clinical care (history, examination, laboratory testing, assessment, treatment, additional screening, counseling), was selected as standard of care by a panel of 5 STI experts representing emergency department (ED), obstetrics/gynecology (Ob/Gyn), family medicine (FM), primary care (PC), and infectious disease. Final measures were piloted with 50 charts per sex from the STI Clinic and age, sex, and visit date-matched charts from PC, FM, ED, and Ob/Gyn. Performance was scored as compliance among individual measures within 7 domains, standardized to add up to one to adjust for variable number of measures per domain, with an overall score of 7 indicating complete adherence to standards. RESULTS: Expert review process took 2 weeks and resulted in 24 and 34 final measures for male and female patients, respectively. Performance on 7 clinical domains ranged from 3.16 to 4.36 for male patients and 3.17 to 4.33 for female patients. Sexually transmitted infection clinic seemed to score higher on laboratory testing, additional screening, and counseling, but lower on examination and assessment, and ED seemed to score higher on examination and treatment, PC and FM on laboratory testing for male patients and on examination and treatment for female patients, and Ob/Gyn on treatment. CONCLUSIONS: An instrument to discern standard of care and identify strengths and weaknesses in specific domains of clinical documentation for patients presenting with STI complaints can be developed and implemented for quality evaluation across care settings. Further research is needed on whether these findings can be integrated into site-specific quality improvement processes and linked to cost analyses.
