As in heart failure, obstructive and central sleep apnoea (OSA and CSA, respectively) are common in end-stage renal disease. Fluid overload characterises end-stage renal disease and heart failure, and in heart failure plays a role in the pathogenesis of OSA and CSA. We postulated that in end-stage renal disease patients, those with sleep apnoea would have greater fluid volume overload than those without.End-stage renal disease patients on thrice-weekly haemodialysis underwent overnight polysomnography on a nondialysis day to determine their apnoea–hypopnoea index (AHI). Extracellular fluid volume of the total body, neck, thorax and right leg were measured using bioelectrical impedance.28 patients had an AHI ≥15 (sleep apnoea group; OSA:CSA 21:7) and 12 had an AHI <15 (no sleep apnoea group). Total body extracellular fluid volume was 2.6 L greater in the sleep apnoea group than in the no sleep apnoea group (p=0.006). Neck, thorax, and leg fluid volumes were also greater in the sleep apnoea than the no sleep apnoea group (p<0.05), despite no difference in body mass index (p=0.165).These findings support a role for fluid overload in the pathogenesis of both OSA and CSA in end-stage renal disease.

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.
