Abstract
Importance Although early trials of endovascular renal denervation (RDN) for patients with resistant hypertension (RHTN) reported inconsistent results, ultrasound RDN (uRDN) was found to decrease blood pressure (BP) vs sham at 2 months in patients with RHTN taking stable background medications in the Study of the ReCor Medical Paradise System in Clinical Hypertension (RADIANCE-HTN TRIO) trial. Objectives To report the prespecified analysis of the persistence of the BP effects and safety of uRDN vs sham at 6 months in conjunction with escalating antihypertensive medications. Design, Setting, and Participants This randomized, sham-controlled, clinical trial with outcome assessors and patients blinded to treatment assignment, enrolled patients from March 11, 2016, to March 13, 2020. This was an international, multicenter study conducted in the US and Europe. Participants with daytime ambulatory BP of 135/85 mm Hg or higher after 4 weeks of single-pill triple-combination treatment (angiotensin-receptor blocker, calcium channel blocker, and thiazide diuretic) with estimated glomerular filtration rate (eGFR) of 40 mL/min/1.73 m2 or greater were randomly assigned to uRDN or sham with medications unchanged through 2 months. From 2 to 5 months, if monthly home BP was 135/85 mm Hg or higher, standardized stepped-care antihypertensive treatment starting with aldosterone antagonists was initiated under blinding to treatment assignment. Interventions uRDN vs sham procedure in conjunction with added medications to target BP control. Main Outcomes and Measures Six-month change in medications, change in daytime ambulatory systolic BP, change in home systolic BP adjusted for baseline BP and medications, and safety. Results A total of 65 of 69 participants in the uRDN group and 64 of 67 participants in the sham group (mean [SD] age, 52.4 [8.3] years; 104 male [80.6%]) with a mean (SD) eGFR of 81.5 (22.8) mL/min/1.73 m2 had 6-month daytime ambulatory BP measurements. Fewer medications were added in the uRDN group (mean [SD], 0.7 [1.0] medications) vs sham (mean [SD], 1.1 [1.1] medications; P = .045) and fewer patients in the uRDN group received aldosterone antagonists at 6 months (26 of 65 [40.0%] vs 39 of 64 [60.9%]; P = .02). Despite less intensive standardized stepped-care antihypertensive treatment, mean (SD) daytime ambulatory BP at 6 months was 138.3 (15.1) mm Hg with uRDN vs 139.0 (14.3) mm Hg with sham (additional decreases of -2.4 [16.6] vs -7.0 [16.7] mm Hg from month 2, respectively), whereas home SBP was lowered to a greater extent with uRDN by 4.3 mm Hg (95% CI, 0.5-8.1 mm Hg; P = .03) in a mixed model adjusting for baseline and number of medications. Adverse events were infrequent and similar between groups. Conclusions and Relevance In this study, in patients with RHTN initially randomly assigned to uRDN or a sham procedure and who had persistent elevation of BP at 2 months after the procedure, standardized stepped-care antihypertensive treatment escalation resulted in similar BP reduction in both groups at 6 months, with fewer additional medications required in the uRDN group.

Abstract
BACKGROUND The multicenter, international, randomized, blinded, sham-controlled RADIANCE-HTN SOLO trial (A Study of the ReCor Medical Paradise System in Clinical Hypertension) demonstrated a 6.3 mm Hg greater reduction in daytime ambulatory systolic blood pressure (BP) at 2 months by endovascular ultrasound renal denervation (RDN) compared with a sham procedure among patients not treated with antihypertensive medications. We report 6-month results after the addition of a recommended standardized stepped-care antihypertensive treatment to the randomized endovascular procedure under continued blinding to initial treatment. METHODS Patients with a daytime ambulatory BP ≥135/85 mm Hg and <170/105 mm Hg after a 4-week discontinuation of up to 2 antihypertensive medications, and a suitable renal artery anatomy, were randomized to RDN (n=74) or sham (n=72). Patients were to remain off antihypertensive medications throughout the first 2 months of follow-up unless safety BP criteria were exceeded. Between 2 and 5 months, if monthly measured home BP was ≥135/85 mm Hg, a standardized stepped-care antihypertensive treatment was recommended consisting of the sequential addition of amlodipine (5 mg/d), a standard dose of an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and hydrochlorothiazide (12.5 mg/d), followed by the sequential uptitration of hydrochlorothiazide (25 mg/d) and amlodipine (10 mg/d). Outcomes included the 6-month (1) change in daytime ambulatory systolic BP adjusted for medications and baseline systolic BP, (2) medication burden, and (3) safety. RESULTS A total of 69/74 RDN patients and 71/72 sham patients completed the 6-month ambulatory BP measurement. At 6 months, 65.2% of patients in the RDN group were treated with the standardized stepped-care antihypertensive treatment versus 84.5% in the sham group (P=0.008), and the average number of antihypertensive medications and defined daily dose were less in the RDN group than in the sham group (0.9±0.9 versus 1.3±0.9, P=0.010 and 1.4±1.5 versus 2.0±1.8, P=0.018; respectively). Despite less intensive standardized stepped-care antihypertensive treatment, RDN reduced daytime ambulatory systolic BP to a greater extent than sham (-18.1±12.2 versus -15.6±13.2 mm Hg, respectively; difference adjusted for baseline BP and number of medications: -4.3 mm Hg, 95% confidence interval, -7.9 to -0.6, P=0.024). There were no major adverse events in either group through 6 months. CONCLUSIONS The BP-lowering effect of endovascular ultrasound RDN was maintained at 6 months with less prescribed antihypertensive medications compared with a sham control.

Abstract
Early detection of coronary artery dysfunction is of paramount cardiovascular clinical importance, but a noninvasive assessment is lacking. Indeed, the brachial artery flow-mediated dilation test only weakly correlated with acetylcholine-induced coronary artery function ( r=0.36). However, brachial artery flow-mediated dilation methodologies have, over time, substantially improved. This study sought to determine if updates to this technique have improved the relationship with coronary artery function and the noninvasive indication of coronary artery dysfunction. Coronary artery and brachial artery function were assessed in 28 patients referred for cardiac catheterization (61±11 years). Coronary artery function was determined by the change in artery diameter with a 1.82 μg/min intracoronary acetylcholine infusion. Based on the change in vessel diameter, patients were characterized as having dysfunctional coronary arteries (>5% vasoconstriction) or relatively functional coronary arteries (<5% vasoconstriction). Brachial artery function was determined by flow-mediated dilation, adhering to current guidelines. The acetylcholine-induced change in vessel diameter was smaller in patients with dysfunctional compared with relatively functional coronary arteries (-11.8±4.6% versus 5.8±9.8%, P<0.001). Consistent with this, brachial artery flow-mediated dilation was attenuated in patients with dysfunctional compared with relatively functional coronaries (2.9±1.9% versus 6.2±4.2%, P=0.007). Brachial artery flow-mediated dilation was strongly correlated with the acetylcholine-induced change in coronary artery diameter ( r=0.77, P<0.0001) and was a strong indicator of coronary artery dysfunction (receiver operator characteristic=78%). The current data support that updates to the brachial artery flow-mediated dilation technique have strengthened the relationship with coronary artery function, which may now provide a clinically meaningful indication of coronary artery dysfunction.

Abstract
Coronary artery disease of the septal perforator branches can lead to clinical ischemia and conduction abnormalities. Performing interventional procedures in these vessels is frequently impossible because they are small, which makes it difficult to approach them and to select appropriate equipment. Larger septal perforator branches have been treated percutaneously in a few patients; however, the clinical effectiveness and long-term outcomes are not known. We present our experience in managing obstructive septal perforator branch stenosis in 4 patients.

Abstract
Patients with unprotected left main coronary artery (ULMCA) disease are increasingly treated with percutaneous coronary intervention (PCI) using new-generation drug-eluting stents (DES); however, the benefits of DES compared with coronary artery bypass grafting (CABG) in ULMCA remain controversial. This meta-analysis evaluated the effects of PCI with DES compared with CABG for the treatment of ULMCA stenosis. Databases were searched through November 30, 2016. Randomized controlled trials (RCTs) comparing DES with PCI versus CABG for ULMCA stenosis were identified. We calculated summary odds ratios (ORs) and 95% CIs with the random-effects model. The primary outcome was major adverse cardiovascular events, defined as a composite of death from any cause, stroke, or myocardial infarction (MI). The analysis included 4,612 patients from 5 RCTs. Compared with CABG, patients assigned to PCI had a similar rate of major adverse cardiovascular events (OR 1.06, 95% CI 0.79 to 1.43), all-cause mortality (OR 1.03, 95% CI 0.79 to 1.35), cardiovascular death (OR 1.03, 95% CI 0.73 to 1.45), stroke (OR 0.81, 95% CI 0.38 to 1.76), and MI (OR 1.47, 95% CI 0.87 to 2.47). The risk of any repeat revascularization was significantly greater in the PCI group than that in the CABG group (OR 1.85, 95% CI 1.53 to 2.24). In conclusion, our meta-analysis of RCTs suggest that PCI with DES results in comparable mortality, stroke, and MI compared with CABG for revascularization of ULMCA stenosis, with PCI associated with higher rates of repeat revascularization.

Abstract
Background:
Ticagrelor improves survival in patients with acute coronary syndromes (ACS) compared to clopidogrel. Patients are often urgently loaded with P2Y12 inhibitors in the setting of ACS, with little time to consider barriers for continuation in the outpatient setting. We sought to evaluate the association between socioeconomic factors (type of insurance, medication co-payment) and patient choice to switch from ticagrelor to clopidogrel prior to hospital discharge.
Methods:
Our medical center implemented a standardized protocol to load ACS patients with ticagrelor in 2015. During the hospitalization, pharmacists specialized in cardiovascular treatment reviewed the out-of-pocket costs with the patient and assessed their willingness to continue ticagrelor in the outpatient setting. Based on patient choice, some patients were re-loaded with clopidogrel prior to discharge. Using the ACTION Registry-GWTG, we identified all ACS patients who were loaded with ticagrelor since the start of the protocol. We examined the association between switching and socioeconomic factors using chi-squared and rank sum tests.
Results:
We identified a total of 162 ACS patients who were loaded with ticagrelor prior to percutaneous coronary intervention (PCI). Of these patients, 84 (51.9%) were discharged on clopidogrel. Patients who switched to clopidogrel prior to discharge were more likely to have federal outpatient or no prescription insurance (p<0.01), and were more likely to be non-white race (p=0.05; Table). Co-payment data were available for 70.4% of the 162 ticagrelor-loaded patients. For patients who were discharged on ticagrelor, the median monthly co-payment for continuing the drug in the outpatient setting was $18.00 (interquartile range, 18 to 45). The median monthly co-payment for patients who were not discharged on ticagrelor was $253.77 (IQR, 45 to 350; p<0.01).
Conclusion:
Co-payment, race, and prescription insurance are associated with patient choice to switch from ticagrelor to clopidogrel in the ACS setting. This finding implies that socioeconomic factors, namely drug cost, are barriers to implementation of standardized ticagrelor use in ACS patients. While clinical trials suggest a mortality benefit with ticagrelor, real-world practice may not realize this benefit.

Abstract
BACKGROUND Remote ischemic preconditioning (RIPC) has been associated with reduced risk of myocardial injury in patients undergoing cardiovascular surgery, but uncertainty about clinical outcomes remains, particularly in the light of 2 recent large randomized clinical trials (RCTs) which were neutral. We performed a meta-analysis to evaluate the efficacy of RIPC on clinically relevant outcomes in patients undergoing cardiovascular surgery. METHODS We searched PubMed, Cochrane CENTRAL, EMBASE, EBSCO, Web of Science and CINAHL databases from inception through November 30, 2015. RCTs that compared the effects of RIPC vs. control in patients undergoing cardiac and/or vascular surgery were selected. We calculated summary random-effect odds ratios (ORs) and 95% confidence intervals (CI). RESULTS The analysis included 5652 patients from 27 RCTs. RIPC reduced the risk of myocardial infarction (MI) (OR 0.72, 95% CI, 0.52 to 1.00; p=0.05; number needed to treat (NNT)=42), acute renal failure (OR 0.73, 95% CI, 0.53 to 1.00; p=0.05; NNT=44) as well as the composite of all cause mortality, MI, stroke or acute renal failure (OR 0.60, 95% CI, 0.39 to 0.90; p=0.01; NNT=25). No significant difference between RIPC and the control groups was observed for the outcome of all-cause mortality (OR 1.10, 95% CI, 0.81 to 1.51). Randomization to RIPC group was also associated with significantly shorter hospital stay (weighted mean difference -0.15days; 95% CI -0.27 to -0.03days). CONCLUSIONS RIPC did not decrease overall mortality, but was associated with less MI and acute renal failure and shorter hospitalizations in patients undergoing cardiac or vascular surgery.

Abstract
Background Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy for patients presenting with ST‐segment elevation myocardial infarction; however, to be effective, PCI must be performed in a timely manner. Rural regions are at a severe disadvantage, given the relatively sparse number of PCI hospitals and long transport times. Methods and Results We developed a standardized treatment and transfer protocol for ST‐segment elevation myocardial infarction in the rural state of Wyoming. The study design compared the time‐to‐treatment outcomes during the pre‐ and postintervention periods. Details of the program, changes in reperfusion strategies over time, and outcome improvements in treatment times were reported. From January 1, 2013, to December 31, 2014, 889 patients were treated in 11 PCI‐capable hospitals (4 in Wyoming, 7 in adjoining states). Given the large geographic distance in the state (median of 47 miles between patient and PCI center), 52% of all patients were transfers, and 36% were administered fibrinolysis at the referral facility. Following the intervention, there was a significant shift toward greater use of primary PCI as the dominant reperfusion strategy (from 47% to 60%, P=0.002), and the median total ischemic time from symptom onset to arterial reperfusion was decreased by 92 minutes (P<0.001). There was a similar significant reduction in median time from receiving center door to balloon of 11 minutes less than the baseline time (P<0.01). Conclusions Rural systems of care for ST‐segment elevation myocardial infarction require increased levels of cooperation between emergency medical services agencies and hospitals. This study confirms that total ischemic times can be reduced through a coordinated rural statewide initiative.

Abstract
Introduction:
Regional systems of care for ST-elevation myocardial infarction (STEMI), such as in Minnesota and North Carolina, have demonstrated improvements in quality of care outcomes. The objective in this study was to collect baseline data on Wyoming statewide STEMI incidence and assess changes in ischemic times and mortality following deployment of a statewide, system of care initiative in the rural state of Wyoming.
Methods:
American Heart Association organized a STEMI initiative in 2012 in Wyoming to address the needs for enhanced rural cardiovascular care. Participating were all 10 STEMI-receiving centers in and around the state, 25 acute care/critical access hospitals, Wyoming Department of Health, 56 emergency medical service (EMS) agencies, and hundreds of volunteer multidisciplinary stakeholders. The initiative deployed approximately 30 training programs, placed 165 12-lead electrocardiogram (ECG) devices in ambulance service, and developed dozens of protocols concerning transfers, treatment, and transport for Wyoming and surrounding border-states. The study design was pre-posttest design, using observational methods of de-identified myocardial infarction data extracted from all 10 participating percutaneous coronary intervention (PCI) facilities’ National Cardiovascular Data Registry (NCDR) submissions. There were 2,301 total MI’s, and 889 STEMIs during calendar years 2013-2014 (24 months). We established the first two quarters as our baseline period, and compared differences in median values using Kruskal-Wallis (KW) and chi-square analyses of variances relative to the the subsequent 6 quarters across several outcome measures (total ischemic time, mortality, thrombolytic administration rates).
Results:
Wyoming has an extremely high transfer rates into PCI, over twice the national average (62%). These transfers produced a long total ischemic time of 291 minutes (nearly 5 hours) in the baseline period, with door-in-door-out times consuming nearly 120 minutes, median. There was a statistically significant 51 minute median reduction in total ischemic times following the program (291 in baseline quarters vs. 241 minutes in subsequent post-intervention periods; KW χ2=4.327, p<.05). There was simultaneously a significant increase in the percent of patients undergoing primary PCI (pPCI) from 54% to 57% (χ2=7.610, p<.01), coupled with a statistically significant reduction in the rate of thrombolytic administration s (46% in the baseline period vs. 37% in the subsequent periods; χ2=6.359, p<.05). Mortality rates were lower than national benchmarks, averaging 3.9% for all MI (5.3% for STEMI), but there were no statistical changes in mortality rates over time.
Conclusions Mission:
Lifeline Wyoming demonstrated statistically significant reductions in median total ischemic time and higher primary PCI reperfusion rates.

Abstract
Background Initial catheter-based renal sympathetic denervation (RSD) studies demonstrated promising results in showing a significant reduction of blood pressure, while recent data were less successful. As an alternative approach, the objective of this study was to evaluate the feasibility of using magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) to perform RSD in a porcine model. Methods An intravascular fiber optic temperature probe was used to confirm energy delivery during MRgHIFU. This technique was evaluated both in a vascular phantom and in a normotensive pig model. Five animals underwent unilateral RSD using MRgHIFU, and both safety and efficacy were assessed. MRI was used to evaluate the acoustic window, target sonications, monitor the near-field treatment region using MR thermometry imaging, and assess the status of tissues post-procedure. An intravascular fiber optic temperature probe verified energy delivery. Animals were sacrificed 6 to 9 days post-treatment, and pathological analysis was performed. The norepinephrine present in the kidney medulla was assessed post-mortem. Results All animals tolerated the procedure well with no observed complications. The fiber optic temperature probe placed in the target renal artery confirmed energy delivery during MRgHIFU, measuring larger temperature rises when the MRgHIFU beam location was focused closer to the tip of the probe. Following ablation, a significant reduction (p = 0.04) of cross-sectional area of nerve bundles between the treated and untreated renal arteries was observed in all of the animals with treated nerves presenting increased cellular infiltrate and fibrosis. A reduction of norepinephrine (p = 0.14) in the kidney medulla tissue was also observed. There was no indication of tissue damage in arterial walls. Conclusions Performing renal denervation non-invasively with MRgHIFU was shown to be both safe and effective as determined by norepinephrine levels in a porcine model. This approach may be a promising alternative to catheter-based strategies.

Abstract
Cardiovascular (CV) assessment in prerenal transplant patients varies by center. Current guidelines recommend stress testing for candidates if ≥ 3 CV risk factors exist. We evaluated the CV assessment and management in 685 patients referred for kidney transplant over a 7-year period. All patients had CV risk factors, and the most common cause of end-stage renal disease was diabetes. Thirty-three percent (n = 229) underwent coronary angiography. The sensitivity of stress testing to detect obstructive coronary artery disease (CAD) was poor (0.26). Patients who had no CAD, nonobstructive CAD, or CAD with intervention had significantly higher event-free survival compared with patients with obstructive CAD without intervention. There were no adverse clinical events (death, myocardial infarction, stroke, revascularization, and graft failure) within 30 days post-transplant in patients who had preoperative angiography (n = 77). Of the transplanted patients who did not have an angiogram (n = 289), there were 8 clinical events (6 myocardial infarctions) in the first 30 days. In conclusion, our results indicate that stress testing and usual risk factors were poor predictors of obstructive CAD and that revascularization may prove beneficial in these patients.

Abstract
BACKGROUND Regional myocardial infarction systems of care have been shown to improve timely access to primary percutaneous coronary intervention (PCI). However, there is a relatively sparse research on rural "frontier" regions. Arrival mode, high rates of interhospital transfers, long transport times, low population density, and mostly volunteer emergency medical services (EMS) distinguish this region from metropolitan systems of care. We sought to assess the effect of interhospital transfers, distance, and arrival mode on total ischemic times for patients with ST-elevation myocardial infarctions undergoing primary PCI. METHODS We assessed patient data from our observational cohort of 395 patients with ST-elevation myocardial infarction with PCI as their primary treatment strategy. Data came from the 10 PCI hospitals participating in the Wyoming Mission: Lifeline program from January 2013 to September 2014. We performed both regression and tests of differences. RESULTS Median total ischemic time was nearly 2.7 times greater in transferred patients than those presenting directly (379 vs 140 minutes). Distance in miles traveled between patient's home and PCI facility was 2.5 times larger in transfer patients (51 vs 20 miles). Emergency medical services arrival was associated with 23% shorter total ischemic times than self-arrival. CONCLUSIONS Transfer patients from referral hospitals had significantly greater total ischemic time, and use of EMS was associated with significantly lower times. Transport distance was mixed in its effect. These findings suggest a continued focus on improving transitions between referral and receiving centers and enhancing coordination in rural systems of care to reduce the multiplier effect of transfers on total ischemic time.

Abstract
BACKGROUND Obesity is associated with significantly increased cardiovascular mortality that has been attributed, in part, to sympathetic activation. Gastric bypass surgery (GBS) appears to increase long-term survival in the severely obese, but the mechanisms responsible for this increase are still being sought. Heart rate (HR) recovery after exercise reflects the balance of cardiac autonomic input from the sympathetic and parasympathetic systems. Blunted HR recovery is a very powerful predictor of increased mortality, whereas enhanced HR recovery portends a good prognosis. OBJECTIVE The purpose of this study was to evaluate the effect of marked weight loss achieved via GBS on HR recovery. METHODS Severely obese patients underwent submaximal exercise testing (80% predicted maximum HR) at baseline and 2 years after GBS (n = 153) or nonsurgical treatment (n = 188). RESULTS Patients in the GBS group lost an average of 100 ± 37 lb compared to 3 ± 22 lb in the nonsurgical group (P <.001, GBS vs nonsurgical). Resting HR decreased from 73 bpm to 60 bpm in the GBS group and from 74 bpm to 68 bpm in nonsurgical patients (P <.001). HR recovery improved by 13 bpm in the GBS group but did not change in the nonsurgical group (P <.001 GBS vs nonsurgical). In multivariable analysis, the independent correlates of HR recovery at the 2-year time point were resting HR, treadmill time, age, body mass index, and HOMA-IR (an index of insulin resistance). CONCLUSION Marked weight loss 2 years after GBS resulted in a significant decrease in resting HR and an enhancement in HR recovery after exercise. These changes likely are attributable to improvement in insulin sensitivity and cardiac autonomic balance. Whether and to what extent this contributes to a reduction in cardiovascular mortality with GBS remains to be determined.

Abstract
Ecological behaviors of uropathogenic bacteria in the infected urine were characterized, and they were compared to those in vitro cultivation. The organisms directly collected from the infected urine revealed no piliation, but when they were isolated and cultured in heart infusion broth (HIB), the pili appeared. The pili were identified as Type I pili as examined by immunogold electron microscopy. Although the organisms directly collected from the infected urine did not have pili and did not agglutinate against anti-Type I pili anti-serum, the whole cell lysate analysis by western blotting revealed that the organisms express Type I pili antigen intracellularly. The organisms in some cases revealed a capsule formation in the urine, but it disappeared when cultured in vitro. Hemolytic Escherichia coli were isolated from 9 cases out of 20 with acute cystitis, however, hemolysin was not detected from the infected urine and the organisms. When they were cultured in HIB, all strains produced the hemolysin. The composition of outer membrane proteins (OMPs) of the organisms in the infected urine was clearly different from those in vitro cultivation. As the most prominent finding, a 70 kDa OMP of the organisms in the infected urine disappeared in vitro. Antibacterial activities of several drugs examined in healthy human urine and in HIB were variable from drug to drug. The mean value of minimum inhibitory concentration (MIC) of ofloxasin was 25 times higher in the urine than in HIB, whereas the MIC of erythromycin was almost equal in both conditions.

Abstract
Cefpodoxime (CPDX-PR) was evaluated clinically in respiratory tract infections. The results obtained are summarized as follows; 1. The total number of the patients who were treated with CPDX-PR was 61, out of whom 53 cases were evaluated for clinical efficacy and 55 cases were investigated for the safety of the drug. CPDX-PR was given orally twice a day at 100-200 mg for 5-21 days. 2. Clinical efficacies were excellent in 9 patients, good in 36, fair in 4 and poor in 4. The overall clinical efficacy was 84.9%. In particular, CPDX-PR showed satisfactory efficacy for acute respiratory infections and mild chronic respiratory infections, with efficacy rates of 88.6% (31/35) and 100% (8/8), respectively. 3. No adverse reactions was observed, but slight and transient elevation of BUN was noted. In conclusion, it has been confirmed that CPDX-PR is an excellent and safe drug for the treatment of the respiratory tract infections.

Abstract
A 80 year-old male was transferred to our department on 18th Aug. 1988, for high fever and clouding of the consciousness. He had been treated with steroid hormone (betamethasone 3.0 mg/day for 15 days) for his uveitis. Enterococcus faecium was isolated from both blood and spinal fluid, and then Strongyloides sterocoralis was revealed both in the sputum and stool. Anti-Human T-cell leukemia virus 1 (HTLV-1) antibody was also positive serologically. At first, beta-lactam antibiotics were used for the treatment of purulent meningitis and sepsis, but after performing sensitivity tests for E. faecium, the antibiotics were changed to rifampicin (RFP), fosfomycin (FOM) and ofloxacin (OFLX) for their excellent activity against the organism. After the clinical symptoms, subsided, thiabendazole was used for disseminated strongyloidiasis in daily doses of 2,500 mg for six days initially. The drug was used three times with two week intervals. Both bacterial and parasite infections subsided and no recurrence has been noticed until now. This is the first case of meningitis caused by E. facium complicated with strongyloidiasis.
