Abstract Background Coronary microvascular dysfunction (CMD) is common in end-stage renal disease (ESRD) and is an adverse prognostic marker. Coronary flow velocity reserve (CFVR) is a measure of coronary microvascular function and can be assessed using Doppler echocardiography. Reduced CFVR in ESRD has been attributed to factors such as diabetes, hypertension and left ventricular hypertrophy. The contributory role of other mediators important in the development of cardiovascular disease in ESRD has not been studied. The aim of this study was to examine the prevalence of CMD in a cohort of kidney transplant candidates and to look for associations of CMD with markers of anaemia, bone mineral metabolism and chronic inflammation. Methods Twenty-two kidney transplant candidates with ESRD were studied with myocardial contrast echocardiography, Doppler CFVR assessment and serum multiplex immunoassay analysis. Individuals with diabetes, uncontrolled hypertension or ischaemic heart disease were excluded. Results 7/22 subjects had CMD (defined as CFVR < 2). Demographic, laboratory and echocardiographic parameters and serum biomarkers were similar between subjects with and without CMD. Subjects with CMD had significantly lower haemoglobin than subjects without CMD (102 g/L ± 12 vs. 117 g/L ± 11, p = 0.008). There was a positive correlation between haemoglobin and CFVR (r = 0.7, p = 0.001). Similar results were seen for haematocrit. In regression analyses, haemoglobin was an independent predictor of CFVR (β = 0.041 95% confidence interval 0.012–0.071, p = 0.009) and of CFVR < 2 (odds ratio 0.85 95% confidence interval 0.74–0.98, p = 0.022). Conclusions Among kidney transplant candidates with ESRD, there is a high prevalence of CMD, despite the absence of traditional risk factors. Anaemia may be a potential driver of microvascular dysfunction in this population and requires further investigation.

No single-tablet antiretroviral (ARV) regimens (STRs) are approved for patients with human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) on hemodialysis (HD). Based on known pharmacokinetic (PK) properties, abacavir (ABC)/lamivudine (3TC)/dolutegravir (DTG) STR may represent a promising option. This case series presents the safety and efficacy of ABC/3TC/DTG STR in patients with HIV and ESRD on HD. Patients were included if they were HIV-positive, maintained on intermittent HD for ESRD, switched to an ARV regimen containing ABC/3TC/DTG, and had at least one set of virologic data before and after the switch. Average age (±standard deviation) was 59 (±8) years. The majority of patients were cis-gender male and non-Hispanic Black. Only one demonstrated clinically significant resistance at baseline. All were on multiple-tablet regimens prior to the switch. Five patients (83%) achieved undetectable HIV-RNA after the switch while only four patients (46%) were undetectable immediately prior. No decline in immune function was noted. ABC/3TC/DTG STR was well tolerated. Only one patient self-reported an adverse event (nausea), which resolved without drug discontinuation. Based on these data, it appears that ABC/3TC/DTG may be a safe and effective ARV-STR option for patients with HIV and ESRD on HD. A larger trial including a PK analysis is needed to confirm these findings.

A 54-year-old man with remote large cell non-Hodgkin’s lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening throughout the coronary vasculature. Given concern for IgG4-related disease (IgG4-RD), a renal biopsy was pursued that confirmed the diagnosis. 18F-fluorodeoxyglucose positron emission tomography-CT identified only mild aortic inflammation. The patient was treated with high-dose steroids and rituximab. The serological inflammatory markers improved, and he underwent coronary artery bypass grafting. Pericardial, aortic adventitial, left internal mammary artery, and saphenous vein biopsies showed cardiovascular involvement of IgG4-RD. The patient has been maintained on rituximab with normalization of his LVEF and no recurrence of chest pain over the past eighteen months. IgG4-RD is a fibroinflammatory systemic disease newly described in 2003 and only recently found to involve the cardiovascular system with several reports of peripheral aneurysmal disease. To our knowledge, the current case represents the first report of a patient successfully treated for biopsy-proven IgG4-RD associated with coronary artery disease and left ventricular systolic dysfunction. IgG4-RD may represent a novel mechanism underlying some forms of peripheral and coronary arterial disease and may offer new insights into vascular biology.

Rationale: End-stage renal disease (ESRD) patients have high annual mortality mainly due to cardiovascular causes. The acute effects of obstructive and central sleep apnea on cardiac function in ESRD patients have not been determined. We therefore tested, in patients with ESRD, the hypotheses that (1) sleep apnea induces deterioration in cardiac function overnight and (2) attenuation of sleep apnea severity by ultrafiltration (UF) attenuates this deterioration. Methods: At baseline, ESRD patients, on conventional hemodialysis, with left ventricular ejection fraction (LVEF) >45% had polysomnography (PSG) performed on a non-dialysis day to determine the apnea-hypopnea index (AHI). Echocardiography was performed at the bedside, before and after sleep. Isovolumetric contraction time divided by left ventricular ejection time (IVCT/ET) and isovolumetric relaxation time divided by ET (IVRT/ET) were measured by tissue doppler imaging. The myocardial performance index (MPI), a composite of systolic and diastolic function was also calculated. One week later, subjects with sleep apnea (AHI ≥15) had fluid removed by UF, followed by repeat PSG and echocardiography. ­Results: Fifteen subjects had baseline measurements, of which 7 had an AHI <15 (no–sleep-apnea group) and 8 had an AHI ≥15 (sleep-apnea group). At baseline, there was no overnight change in the LVEF in either the no-sleep-apnea group or the sleep-apnea group. In the no-sleep-apnea group, there was also no overnight change in MPI, IVCT/ET and IVRT/ET. However, in the sleep-apnea group there were overnight increases in MPI, IVCT/ET and IVRT/ET (p = 0.008, 0.007 and 0.031, respectively), indicating deterioration in systolic and diastolic function. Following fluid removal by UF in the sleep-apnea group, the AHI decreased by 48.7% (p = 0.012) and overnight increases in MPI, IVCT/ET and IVRT/ET observed at baseline were abolished. Conclusions: In ESRD, cardiac function deteriorates overnight in those with sleep apnea, but not in those without sleep apnea. This overnight deterioration in the sleep-apnea group may be at least partially due to sleep apnea, since attenuation of sleep apnea by UF was accompanied by elimination of this deleterious overnight effect.
