Abstract Background Patients with injection drug use (IDU) have increased risk of developing infective endocarditis (IE). Previous studies have reported recurrent IE, increased duration of hospital stay, poor adherence and compliance as well as higher mortality and worse outcomes after surgery in the IDU-IE patient group. Further studies are needed to provide a basis for optimized care and prevention of readmissions in this population. This study aims to describe the clinical characteristics and outcomes among patients with IDU-IE. Methods Data of adults with IDU-IE and non-IDU-IE, treated between 2008 and 2017 at the Karolinska University Hospital in Stockholm were obtained from the Swedish National Registry of Infective Endocarditis. Clinical characteristics, microbiological results, treatment durations, results from echocardiography and in-hospital mortality were compared between the groups. Results Of the total 522 patients, 165 (32%) had IDU-IE. Patients with IDU-IE were younger than the patients with non-IDU-IE (mean age IDU-IE: 41.6 years, SD 11.9 years; non-IDU-IE: 64.3 years, SD 16.4 years; P <  0.01). No difference in distribution of gender was observed, 33% were females in both the IDU-IE and the non-IDU-IE group. History of previous IE (IDU-IE: n = 49, 30%; non-IDU-IE: n = 34, 10%; P <  0.01) and vascular phenomena (IDU-IE: n = 101, 61%; non-IDU-IE: n = 120, 34%; P <  0.01) were more common among patients with IDU-IE while prosthetic heart valves (IDU-IE: n = 12, 7%; non-IDU-IE: n = 83, 23%; P <  0.01) and known valvular disease (IDU-IE: n = 3, 2%; non-IDU-IE: n = 78, 22%; P <  0.01) were more common among patients with non-IDU-IE. Aetiology of Staphylococcus aureus (IDU-IE: n = 123, 75%; non-IDU-IE: n = 118, 33%; P <  0.01) as well as tricuspid (IDU-IE: n = 91, 55%; non-IDU-IE: n = 23, 6%; P <  0.01) or pulmonary valve vegetations (IDU-IE: n = 7, 4%; non-IDU-IE: n = 2, 1%; P <  0.01) were more common in the IDU-IE group. The overall incidence of IDU-IE decreased during the study period, while the incidence of definite IE increased (P <  0.01). Conclusions This study presents that patients with IDU-IE were younger, less frequently treated with surgery and had higher prevalence of vascular phenomena and history of previous IE, aspects that are important for improved management of this population.

Abstract Background: Patients with injection drug use (IDU) have increased risk of developing infective endocarditis (IE), however data of these patients are scarce and need to be explored further. This study aims to describe the clinical characteristics and outcomes among patients with IDU-IE.Methods: Data of adults with IDU-IE and non-IDU-IE, treated between 2008-2017 at the Karolinska University Hospital in Stockholm were obtained from the Swedish National Registry of Infective Endocarditis. Clinical characteristics, microbiological results, treatment durations, results from echocardiography and in-hospital mortality were compared between the groups. Results: In total, 165 (32%) of the included patients had IDU-IE. Patients with IDU-IE were younger than the patients with non-IDU-IE (mean age IDU-IE: 41.6 years; non-IDU-IE: 64.3 years; P<0.01). No difference in distribution of genders was observed, 33% women in both groups. History of previous IE (n=49, 30%) and vascular phenomena (n=101, 61%), were more common among patients with IDU-IE while prosthetic heart valves (n=83, 23%) and known valvular disease (n=78, 22%) were more common among patients with non-IDU-IE (P<0.05). Aetiology of Staphylococcus aureus (n=121, 73%) and tricuspid (n=91, 55%) or pulmonary valve (n=7, 4%) vegetations were more common among IDU-IE (P<0.05). The overall incidence of IDU-IE decreased during the study period, while the incidence of definite IE increased (P<0.01). Conclusions: Patients with IDU-IE were younger, frequently presenting with right-sided vegetations and S. aureus aetiology, and were less frequently treated with surgery. Patients with IDU-IE had higher prevalence of vascular phenomena and history of previous IE, aspects that are important for improved management of this population.

Abstract Background Street-based female sex workers (FSWs) are highly at risk of HIV and other harms associated with sex work. We assessed the prevalence of non-injection and injection drug use and their associated factors among street-based FSWs in Iran. Methods We recruited 898 FSWs from 414 venues across 19 major cities in Iran between October 2016 and March 2017. Correlates of lifetime and past-month non-injection and injection drug use were assessed through multivariable logistic regression models. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were reported. Results Lifetime and past-month non-injection drug use were reported by 60.3% (95% CI 51, 84) and 47.2% (95% CI 38, 67) of FSWs, respectively. The prevalence of lifetime and past-month injection drug use were 8.6% (95% CI 6.9, 10.7) and 3.7% (95% CI 2.6, 5.2), respectively. Recent non-injection drug use was associated with divorced marital status (AOR 2.00, 95% CI 1.07, 3.74), temporary marriage (AOR 4.31 [1.79, 10.40]), had > 30 clients per month (AOR 2.76 [1.29, 5.90]), ever alcohol use (AOR 3.03 [1.92, 6.79]), and history of incarceration (AOR 7.65 [3.89, 15.30]). Similarly, lifetime injection drug use was associated with ever alcohol use (AOR 2.74 [1.20–6.20]), ever incarceration (AOR 5.06 [2.48–10.28]), and ever group sex (AOR 2.44 [1.21–4.92]). Conclusions Non-injection and injection drug use are prevalent among street-based FSWs in Iran. Further prevention programs are needed to address and reduce harms associated with drug use among this vulnerable population in Iran.

Significant Difference

AbstractBackgroundInfective endocarditis (IE) often requires surgical intervention. An increasingly common cause of IE is injection drug use (IDU-IE). There is conflicting evidence on whether postoperative mortality differs between people with IDU-IE and people with IE from etiologies other than injection drug use (non–IDU-IE). In this manuscript, we compare short-term postoperative mortality in IDU-IE vs non–IDU-IE through systematic review and meta-analysis.MethodsThe review was conducted according to the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Publication databases were queried for key terms included in articles up to September 2017. Randomized controlled trials, prospective cohorts, or retrospective cohorts that reported on 30-day mortality or in-hospital/operative mortality following valve surgery and that compared outcomes between IDU-IE and non–IDU-IE were included.ResultsThirteen studies with 1593 patients (n = 341 [21.4%] IDU-IE) were included in the meta-analysis. IDU-IE patients more frequently had tricuspid valve infection, Staphylococcus infection, and heart failure before surgery. Meta-analysis revealed no statistically significant difference in 30-day postsurgical mortality or in-hospital mortality between the 2 groups.ConclusionsDespite differing preoperative clinical characteristics, early postoperative mortality does not differ between IDU-IE and non–IDU-IE patients who undergo valve surgery. Future research on long-term outcomes following valve replacement is needed to identify opportunities for improved healthcare delivery with IDU-IE.

Abstract Background Sepsis is an important cause of morbidity and mortality in the pregnant patient. Injection drug use in pregnant populations has led to increased cases of bacteremia and infective endocarditis (IE) due to Staphylococcus aureus. We describe all cases of S. aureus bacteremia and IE among admitted pregnant patients at our hospital over a 6-year period. Methods This was a retrospective review of pregnant patients hospitalized with S. aureus bacteremia between April 2013 and November 2019. Maternal in-hospital mortality and fetal in-hospital mortality were the primary outcomes measured; the secondary outcome was the rate of 6-month maternal readmission. Results Twenty-seven patients were included; 15 (56%) had IE. The median (interquartile range [IQR]) age was 29 (25–33) years; 22 (82%) patients had methicillin-resistant S. aureus. Infection onset occurred at a median (IQR) of 29 (23–34) weeks’ gestation. Twenty-three (85%) mothers reported active injection drug use, and 21 (78%) were hepatitis C seropositive. Fifteen (56%) mothers required intensive care unit (ICU) care. Twenty-two (81%) patients delivered 23 babies; of the remaining 5 mothers, 3 (11%) were lost to follow-up and 2 (7%) terminated pregnancy. Sixteen (73%) babies required neonatal ICU care, and 4/25 (16%) infants/fetuses died during hospitalization. One (4%) mother died during hospitalization, and 7/26 (27%) mothers were readmitted to the hospital within 6 months for infectious complications. Conclusions Injection drug use is a modifiable risk factor for S. aureus bacteremia in pregnancy. Fetal outcomes were poor, and mothers were frequently readmitted secondary to infection. Future targeted interventions are needed to curtail injection drug use in this population.

Abstract Background No International Classification of Diseases, 10th revision (ICD-10), diagnosis code exists for injection drug use–associated infective endocarditis (IDU-IE). Instead, public health researchers regularly use combinations of nonspecific ICD-10 codes to identify IDU-IE; however, the accuracy of these codes has not been evaluated. Methods We compared commonly used ICD-10 diagnosis codes for IDU-IE with a prospectively collected patient cohort diagnosed with IDU-IE at Barnes-Jewish Hospital to determine the accuracy of ICD-10 diagnosis codes used in IDU-IE research. Results ICD-10 diagnosis codes historically used to identify IDU-IE were inaccurate, missing 36.0% and misclassifying 56.4% of patients prospectively identified in this cohort. Use of these nonspecific ICD-10 diagnosis codes resulted in substantial biases against the benefit of medications for opioid use disorder (MOUD) with relation to both AMA discharge and all-cause mortality. Specifically, when data from all patients with ICD-10 code combinations suggestive of IDU-IE were used, MOUD was associated with an increased risk of AMA discharge (relative risk [RR], 1.12; 95% CI, 0.48–2.64). In contrast, when only patients confirmed by chart review as having IDU-IE were analyzed, MOUD was protective (RR, 0.49; 95% CI, 0.19–1.22). Use of MOUD was associated with a protective effect in time to all-cause mortality in Kaplan-Meier analysis only when confirmed IDU-IE cases were analyzed (P = .007). Conclusions Studies using nonspecific ICD-10 diagnosis codes for IDU-IE should be interpreted with caution. In the setting of an ongoing overdose crisis and a syndemic of infectious complications, a specific ICD-10 diagnosis code for IDU-IE is urgently needed.
