"Shaping the new freedom": A reflexive thematic analysis on patients' post cure needs after years of living with hepatitis C.

BACKGROUND: Direct-acting antivirals present a treatment opportunity that provides high rates of sustained viral response even for people who have lived for years with hepatitis C virus (HCV) infection. While it is known that liver-related morbidity and mortality can be decreased and many symptoms reversed, this population's need for post-treatment professional support has not been extensively assessed. Therefore, our study aimed to describe the experiences of patients cured of chronic HCV infection and explore the meaning of these experiences regarding specific follow-up care needs within the context of the Swiss health system. METHODS: For this qualitative study, we applied a reflexive thematic analysis approach with a social constructivist orientation. Twelve participants shared their experiences of being cured and their needs regarding follow-up care. Subsequently, the data were analysed in an iterative process based on Braun and Clarke's six phases of analysis. RESULTS: In the overarching theme, participants summarised their new situation with the statement, "being cured feels like being released from a cage". They experienced striking health improvements with overwhelmingly positive influences on their everyday lives. This experience was characterised for all participants by important changes on three levels. We categorised these in three sub-themes: a) "the ball and chain have been lightened": this sub-theme illustrates the reduction of social limitations and emotional stress; b) "the gnawing at the liver has let up": this signifies relief from physical symptoms and strongly improved well-being. And under the third sub-theme, "shaping the new freedom", the participants described their new situation as a sometimes-stressful challenge because they had to reorient their self-management. They shared their concerns regarding the ongoing stigma of HCV infection, feeling insecure in their own health after being cured, and learning how to use their heightened sense of confidence and openness to enact behavioural changes that would improve their health-related lifestyles. CONCLUSION: The findings of this study provide insights into treatment experiences of patients cured of chronic HCV infection and the need for follow-up care even after successful virus eradication. The results can sensitise healthcare professionals to patients' post-cure challenges and guide their care interventions. Some of these challenges, such as dealing with stigma, can be addressed during treatment; other needs, like providing motivation to engage in healthy behaviour, may warrant targeted follow-up.

Hyperechogenic intimal lesions and wall thickness of the temporal and facial arteries in elderly patients with arterial occlusions of the eye.

OBJECTIVE: To determine the association of arteriosclerosis, characterised by hyperechogenic intimal lesions (HIL), with wall thickness of the temporal and facial arteries in elderly patients with ocular arterial occlusions. METHODS: Patients suffering from non-arteritic ocular perfusion disorders were included. High-resolution compression sonography (18 MHz) images of the temporal arteries (frontal and parietal branch at the upper margin of the auricle) and facial arteries (at the crossing point of the artery over the mandible) were analysed for the presence of HIL (grade 0: absent; grade 1: moderate; grade 2: severe). Characteristics of patients with and without evidence of HIL >grade 1 were compared. RESULTS: In total, 330 cranial artery segments of 55 patients were analysed. HIL ≥grade 1 was present in 13.0% of all artery segments and in 38.1% of all patients. Patients with HIL ≥grade 1 in at least one arterial segment displayed significantly increased maximum wall thickness of the temporal arteries (0.62±0.23 mm vs 0.50±0.13 mm; p<0.01) and facial arteries (0.71±0.20 mm vs 0.54±0.19 mm; p=0.01). Patients with at least one temporal or facial artery segment with HIL were older, more often male and more frequently suffered from diabetes mellitus. CONCLUSION: The presence of HIL goes along with a significantly increased wall thickness of the temporal and facial arteries. These findings should be considered when interpreting the results of sonography of the cranial arteries in the diagnostic workup of suspected giant cell arteritis.

Renin, a marker for left ventricular hypertrophy, in primary aldosteronism: a cohort study.

CONTEXT: Primary aldosteronism (PA) causes left ventricular hypertrophy (LVH) via hemodynamic factors and directly by aldosterone effects. Specific treatment by mineralocorticoid receptor antagonists (MRA) or adrenalectomy (ADX) has been reported to improve LVH. However, the cardiovascular benefit could depend on plasma renin concentration (PRC) in patients on MRA. PATIENTS AND OBJECTIVE: We analyzed data from 184 patients from the Munich center of the German Conn's Registry, who underwent echocardiography at the time of diagnosis and 1 year after treatment. To assess the effect of PRC on cardiac recovery, we stratified patients on MRA according to suppression (n = 46) or non-suppression of PRC (n = 59) at follow-up and compared them to PA patients after ADX (n = 79). RESULTS: At baseline, patients treated by ADX or MRA had comparable left ventricular mass index (LVMI, 61.7 vs 58.9 g/m2.7, P = 0.591). Likewise, patients on MRA had similar LVMI at baseline, when stratified into treatment groups with suppressed and unsuppressed PRC during follow-up (60.0 vs 58.1 g/m2.7, P = 0.576). In all three groups, we observed a significant reduction in LVMI following treatment (P < 0.001). However, patients with suppressed PRC had no decrease in pro-BNP levels, and the reduction of LVMI was less intense than in patients with unsuppressed PRC (4.1 vs 8.2 g/m2.7, P = 0.033) or after ADX (9.3 g/m2.7, P = 0.019). Similarly, in multivariate analysis, higher PRC was correlated with the regression of LVH. CONCLUSION: PA patients with suppressed PRC on MRA show impaired regression of LVH. Therefore, dosing of MRA according to PRC could improve their cardiovascular benefit.

Transocular sonography in acute arterial occlusions of the eye in elderly patients: Diagnostic value of the spot sign.

PURPOSE: To characterize the diagnostic yield of the spot sign in the diagnostic workup of acute arterial occlusions of the eye in elderly patients. METHODS: Clinical characteristics of consecutive patients aged ≥ 50 years with acute central retinal artery occlusion (CRAO), branch retinal artery occlusion (BRAO) or anterior ischemic optic neuropathy (AION) were recorded. Videos of transocular sonography were assessed for the presence of the spot sign by two blinded readers. Group comparisons were made between CRAO-patients with and without the spot sign. Two experienced cardiovascular physicians allocated CRAO-cases to a presumed aetiology, without and with knowledge on the presence/absence of the spot sign. RESULTS: One-hundred-twenty-three patients were included, 46 of whom suffered from CRAO. A spot sign was seen in 32 of 46 of patients with CRAO and in 7 of 23 patients with BRAO. Interobserver agreement was excellent (Cohen`s kappa 0.98). CRAO-patients with the spot sign significantly more frequently had a medical history of cardiovascular disease (62.8 vs. 21.4%, p = 0.03) and left heart valve pathologies (51.9 vs. 10%, p = 0.03). The spot sign was not found in any of the three patients with CRAO secondary to cranial giant cell arteritis. The assumed CRAO aetiology differed in 37% of cases between two cardiovascular physicians, regardless whether transocular sonography findings were known or not. CONCLUSION: The spot sign is a simple sonographic finding with excellent interobserver agreement, which proofs the embolic nature of CRAO, but does not allow exact attribution of the underlying aetiology.

Atherosclerotic Burden and Arterial Stiffness are Not Increased in Patients with Milder Forms of Primary Aldosteronism Compared to Patients with Essential Hypertension.

Patients with primary aldosteronism (PA) are at increased cardiovascular risk, compared to patients with essential hypertension (EH). Cardiovascular damage could depend on PA phenotype, potentially being lower in milder forms of PA. Our aim was to assess atherosclerotic burden and arterial stiffness in 88 prospectively recruited patients, including 44 patients with mild PA and EH respectively. All patients underwent a structured study program, including measurements of ankle-brachial index, oscillometric measurement of central pulse wave velocity (cPWV) and vascular ultrasound examination of the supraaortic arteries, the abdominal aorta, and the femoropopliteal arteries. A plaque score was calculated to estimate atherosclerotic burden for each patient. This is a prospective case-control study set at a tertiary care hospital. Patients with PA and EH matched well for age, gender, blood pressure, BMI, and cardiovascular risk factors such as diabetes mellitus and smoking status. Common carotid intima-media thickness (0.77 vs. 0.75 mm; p=0.997) and cPWV (7.2 vs. 7.1 m/s; p=0.372) were comparable between patients with PA and EH. The atherosclerotic burden, as expressed by the plaque score, did not differ between the two groups (p=0.159). However, after initiation of treatment cPWV was significantly decreased in patients with PA (p=0.017). This study shows that subclinical atherosclerotic burden and arterial stiffness in patients with milder forms of PA is comparable to patients with EH. Nevertheless, specific treatment for PA significantly improved cPWV, which argues for a more liberal use of mineralocorticoid receptor antagonists in patients with arterial hypertension.

Retrobulbar Spot Sign in Metachronous Bilateral Central Retinal Artery Occlusion of Cardioembolic Origin.

ABSTRACT: A 78-year-old man suffered sudden visual loss of his right eye. Five years earlier, he had experienced vision loss of his left eye due to central retinal artery occlusion (CRAO); back then, the etiology for the CRAO was not established. Current ocular ultrasound depicted a hyperechoic spot within the optic nerve in both eyes. Echocardiography identified a calcified mass adherent to the mitral valve as the embolic source of the CRAO. This case shows the value of ocular B-mode ultrasound in demonstration and proof of the etiology for CRAO.

Temporal artery compression sonography for the diagnosis of giant cell arteritis in elderly patients with acute ocular arterial occlusions.

OBJECTIVES: To validate cut-off values of quantitative high-resolution temporal artery compression sonography (TCS) for the diagnosis of cranial GCA (cGCA) in patients with acute arterial ocular occlusions and in an independent control group. METHODS: Consecutive patients who underwent TCS as part of the diagnostic workup of acute arterial ocular occlusions and controls not suffering from ocular ischaemia/systemic vasculitis were included. The diagnostic accuracy of the established TCS cut-off value of maximum temporal artery wall thickness (≥0.7 mm) and a novel numeric TCS score incorporating the degree of wall thickening in the four temporal artery segments assessed (0-3 points per segment) was tested by receiver operating characteristics analysis. Subgroup analyses were performed for female and male patients and patients older and younger than age of 70 years. RESULTS: Of 114 patients with acute ocular arterial occlusions, 30 patients received a final clinical diagnosis of cGCA. The sensitivity and specificity of the ≥0.7 mm TCS cut-off for the diagnosis of cGCA were 100 and 84.5% in the overall cohort. The TCS score did not improve the diagnostic yield (cut-off ≥5; sensitivity 100%, specificity 85.7%). In male patients >70 years of age, the specificity of TCS was limited, secondary to age- and sex-related differences in temporal artery wall thickness, which we confirmed in the independent control group. CONCLUSION: TCS yields high diagnostic accuracy in the diagnosis of cGCA in patients with acute ocular arterial occlusions. Age- and sex-related differences in temporal artery wall thickness influence the diagnostic accuracy of TCS.

Ocular ischaemic complications in giant cell arteritis: CHADS2-score predicts risk of permanent visual impairment.

OBJECTIVES: To identify independent risk factors for permanent visual loss (PVL) in patients with giant cell arteritis (GCA), with a special focus on sonographic findings of the temporal, carotid and subclavian/axillary arteries, and on established scoring systems of ischaemia risk assessment. METHODS: Consecutive patients with a diagnosis of GCA between 2002 and 2013 were retrospectively identified from a prospectively maintained database. Data on clinical characteristics including ophthalmological findings, laboratory values, and sonographic findings of the temporal, carotid an axillary arteries were extracted. CHADS2- and CHA2DS2-VASc-score were calculated. Clinical, laboratory and sonographic characteristics of patients with and without PVL were compared. Multiple logistic regression models were calculated to identify variables independently associated with PVL. RESULTS: One-hundred-fifty-two patients were included in the analysis. PVL occurred in 30.2% of patients, with anterior ischaemic optic neuropathy as predominant underlying cause (91.3%). The frequency of PVL was strongly dependent on the age at diagnosis, with a significant increase after the age of 70 years. In multivariate analysis, axillary artery vasculitis with an odds ratio (OR) of 0.3 and constitutional symptoms with an OR of 0.1 were negatively associated with PVL. A CHADS2-score of 1 (OR 10.7) or ≥2 (OR 25) was associated with a significantly increased risk of PVL. CONCLUSIONS: The risk of PVL secondary to GCA increases with age but is lower in patients presenting with constitutional symptoms and/or exhibiting axillary artery involvement. The CHADS2-score may help to discriminate patients with low vs. high risk of PVL.

Assessment of Disease Activity in Takayasu Arteritis: Potential Role of Contrast-Enhanced Ultrasound.

PURPOSE: To assess the diagnostic value of intima media thickness measurements and contrast-enhanced ultrasound (CEUS) of the supraaortic arteries in the assessment of disease activity in Takayasu arteritis (TA). MATERIALS AND METHODS: Patients with TA and involvement of the carotid and/or subclavian/axillary arteries underwent CEUS imaging in addition to B-mode and color duplex ultrasound. The maximum IMT (mIMT) was measured and high-resolution CEUS of the most prominently thickened vessel segment was performed. Two blinded readers reviewed the CEUS movies, with semiquantitative assessment of microbubble enhancement of the arterial wall (grade 0: no or minimal; grade 1: moderate; grade 2: pronounced). Clinical symptoms, acute phase reactants, and established indices of clinical disease activity (NIH criteria, ITAS score) were recorded. RESULTS: 40 examinations in 17 patients were analyzed. According to clinical judgement, 27 and 13 cases were classified as clinically inactive and active, respectively. An mIMT-cutoff of > 2.7 mm identified active disease with a sensitivity and specificity of 69.2 % and 88.9 %, respectively (area under the curve 0.83). The interobserver agreement of CEUS analysis was substantial (Cohen's kappa 0.76). By consensus reading, 17, 15, and 8 cases were classified as uptake grade 0, grade 1 and grade 2, respectively. Grade 0 uptake was exclusively present in 17 clinically inactive patients. Grade 1 uptake was seen in 10 patients with clinically inactive disease and 5 patients with clinically active disease. Grade 2 uptake was exclusively present in 8 patients with active disease. CONCLUSION: Both sonographic IMT measurements and high-resolution CEUS are promising in the ad-hoc assessment of disease activity in patients with TA.

Human bone marrow contains high levels of extracellular vesicles with a tissue-specific subtype distribution.

INTRODUCTION: Extracellular vesicles (EV) are shed from a broad variety of cells and play an important role in activation of coagulation, cell to cell interaction and transport of membrane components. They are usually measured as circulating EV in peripheral blood (PB) and other body fluids. However, little is known about the distribution, presence and impact of EV and their subpopulations in bone marrow (BM). In our study, we focused on the analysis of different EV subtypes in human BM as compared to EV subsets in PB. METHODS: EV in BM and PB from 12 healthy stem cell donors were measured by flow-cytometry using Annexin V and cell-specific antibodies for hematopoietic stem cells, leucocytes, platelets, red blood cells, and endothelial cells. Additionally, concentrations of tissue factor-bearing EV were evaluated. RESULTS: High numbers of total EV were present in BM (median value [25-75 percentile]: 14.8 x10(9)/l [8.5-19.3]). Non-significantly lower numbers of total EV were measured in PB (9.2 x10(9)/l [3.8-14.5]). However, distribuation of EV subtypes showed substantial differences between BM and PB: In PB, distribution of EV fractions was similar as previously described. Most EV originated from platelets (93.9%), and only few EV were derived from leucocytes (4.5%), erythrocytes (1.8%), endothelial cells (1.0%), and hematopoietic stem cells (0.7%). In contrast, major fractions of BM-EV were derived from red blood cells or erythropoietic cells (43.2%), followed by megacaryocytes / platelets (27.6%), and by leucocytes as well as their progenitor cells (25,7%); only low EV proportions originated from endothelial cells and hematopoietic stem cells (2.0% and 1.5%, respectively). Similar fractions of tissue factor-bearing EV were found in BM and PB (1.3% and 0.9%). CONCULSION: Taken together, we describe EV numbers and their subtype distribution in the BM compartment for the first time. The tissue specific EV distribution reflects BM cell composition and favours the idea of a BM-PB barrier existing not only for cells, but also for EV.

Cortisol Excess in Patients With Primary Aldosteronism Impacts Left Ventricular Hypertrophy.

Context: Primary aldosteronism (PA) represents the most frequent form of endocrine hypertension. Hyperaldosteronism and hypercortisolism both induce excessive left ventricular hypertrophy (LVH) compared with matched essential hypertensives. In recent studies frequent cosecretion of cortisol and aldosterone has been reported in patients with PA. Objective: Our aim was to investigate the impact of cortisol cosecretion on LVH in patients with PA. We determined 24-hour excretion of mineralocorticoids and glucocorticoids by gas chromatography-mass spectrometry and assessed cardiac remodeling using echocardiography initially and 1 year after initiation of treatment of PA. Patients: We included 73 patients from the Munich center of the German Conn's registry: 45 with unilateral aldosterone-producing adenoma and 28 with bilateral adrenal hyperplasia. Results: At the time of diagnosis, 85% of patients with PA showed LVH according to left ventricular mass index [(LVMI); median 62.4 g/m2.7]. LVMI correlated positively with total glucocorticoid excretion (r2 = 0.076, P = 0.018) as well as with tetrahydroaldosterone excretion (r2 = 0.070, P = 0.024). Adrenalectomy led to significantly reduced LVMI in aldosterone-producing adenoma (P < 0.001) whereas mineralocorticoid receptor antagonist therapy in bilateral adrenal patients with hyperplasia reduced LVMI to a lesser degree (P = 0.024). In multivariate analysis, the decrease in LVMI was positively correlated with total glucocorticoid excretion and systolic 24-hour blood pressure, but not with tetrahydroaldosterone excretion. Conclusion: Cortisol excess appears to have an additional impact on cardiac remodeling in patients with PA. Treatment of PA by either adrenalectomy or mineralocorticoid receptor antagonist improves LVMI. This effect was most pronounced in patients with high total glucocorticoid excretion.

Omega-3 Index and Obstructive Sleep Apnea: A Cross-Sectional Study.

STUDY OBJECTIVES: Erythrocyte levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Omega-3 Index) were previously found to be associated with obstructive sleep apnea (OSA) at very low levels (< 5.0%) in only one epidemiologic study. OSA has comorbidities, such as arterial hypertension, heart failure, or major depression, also associated with a low Omega-3 Index. These comorbidities can be improved by increasing intake of EPA and DHA, and thus the Omega-3 Index, preferably to its target range of 8% to 11%. Symptoms of OSA might improve by increasing the Omega-3 Index, but more research is needed. METHODS: In our sleep laboratory, 357 participants with OSA were recruited, and data from 315 participants were evaluated. Three categories of OSA (none/ mild, moderate, severe) were defined based on apnea-hypopnea index. Anthropometrics and lifestyle characteristics (smoking, alcohol, fish intake, omega-3 supplementation) were recorded. Erythrocyte fatty acid compositions were assessed with the HS-Omega-3 Index methodology. RESULTS: The mean Omega-3 Index in all 3 categories of OSA was 5.7%, and no association with OSA was found. There were more male participants with severe OSA (79.7%, P = .042) than females, and participants with severe OSA had a significantly higher body mass index (32.11 ± 6.39 kg/m2, P = .009) than participants with mild or moderate OSA. Lifestyle characteristics were not significantly different. CONCLUSIONS: In contrast to our hypothesis, an Omega-3 Index of 5.7% was not associated with OSA severity. Previously, an Omega-3 Index < 5.0% was associated. Although our results suggest aiming for an Omega-3 Index > 5.7% in an intervention trial with EPA and DHA in OSA, comorbidities of OSA suggest a target range of 8% to 11%.

Bioavailability of Dietary Omega-3 Fatty Acids Added to a Variety of Sausages in Healthy Individuals.

A low Omega-3 Index (eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in erythrocytes) is associated with cardiac, cerebral, and other health issues. Intake of EPA and DHA, but not of alpha-linolenic acid (ALA), increases the Omega-3 Index. We investigated bioavailability, safety, palatability and tolerability of EPA and DHA in a novel source: a variety of sausages. We screened 96 healthy volunteers, and recruited 44 with an Omega-3 Index <5%. Participants were randomly assigned to receive a variety of sausages enriched with approximately 250 mg EPA and DHA per 80 g (n = 22) daily for 8 weeks, or matching placebo sausages (n = 22). All sausages contained approximately 250 mg ALA/80 g. In the verum group, the mean Omega-3 Index increased from 4.18 ± 0.54 to 5.72 ± 0.66% (p < 0.001), while it remained unchanged in the placebo group. While ALA levels increased only in the placebo group, DPA levels increased in both groups. Inter-individual variability in the response was large. The mean increase of the Omega-3 Index per intake of EPA and DHA we observed was higher than for other sources previously studied, indicating superior bioavailability. As increasing production of EPA and DHA is difficult, improvements of bioavailability can facilitate reaching the target range for the Omega-3 Index (8-11%).

A Left-to-Right Shunt After Transfemoral TAVR Using Edwards SAPIEN 3.

Transcatheter aortic valve replacement (TAVR) is used for the treatment of aortic stenosis (AS). Besides major bleeding, conduction blocks, stroke or atrial fibrillation, complications include cardiac perforation with possible left-to-right-shunts. Herein is reported the sixth case of a left-to-right shunt in an 87-year-old man who underwent TAVR using a 29 mm Edwards SAPIEN S3 prosthesis to treat AS. Soon after the procedure, a small channel evolving from the right coronary cusp could be detected on echocardiography. The patient was managed medically.

Bioavailability of fatty acids from krill oil, krill meal and fish oil in healthy subjects--a randomized, single-dose, cross-over trial.

BACKGROUND: Krill contains two marine omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), mainly bound in phospholipids. Typical products from krill are krill oil and krill meal. Fish oils contain EPA and DHA predominantly bound in triglycerides. The difference in the chemical binding of EPA and DHA has been suggested to affect their bioavailability, but little is known on bioavailability of EPA and DHA in krill meal. This study was undertaken to compare the acute bioavailability of two krill products, krill oil and krill meal, with fish oil in healthy subjects. METHODS: A randomized, single-dose, single-blind, cross-over, active-reference trial was conducted in 15 subjects, who ingested krill oil, krill meal and fish oil, each containing approx. 1 700 mg EPA and DHA. Fatty acid compositions of plasma triglycerides and phospholipids were measured repeatedly for 72 hours. The primary efficacy analysis was based on the 72 hour incremental area under the curve (iAUC) of EPA and DHA in plasma phospholipid fatty acids. RESULTS: A larger iAUC for EPA and DHA in plasma phospholipid fatty acids was detected after krill oil (mean 89.08±33.36%×h) than after krill meal (mean 44.97±18.07%xh, p<0.001) or after fish oil (mean 59.15±22.22%×h, p=0.003). Mean iAUC's after krill meal and after fish oil were not different. A large inter-individual variability in response was observed. CONCLUSION: EPA and DHA in krill oil had a higher 72-hour bioavailability than in krill meal or fish oil. Our finding that bioavailabilities of EPA and DHA in krill meal and fish oil were not different argues against the interpretation that phospholipids are better absorbed than triglycerides. Longer-term studies using a parameter reflecting tissue fatty acid composition, like erythrocyte EPA plus DHA are needed. TRIAL REGISTRATION: NCT02089165.

Cellular origin of platelet-derived microparticles in vivo.

INTRODUCTION: Microparticles (MP), presumably of platelet origin, are the most abundant microparticles in blood. To which extent such MP may also directly originate from megakaryocytes, however, is unknown. During hematopoietic stem cell transplantation, patients undergo total body irradiation which leads to an irreversible destruction of hematopoiesis. MATERIAL AND METHODS: We studied the levels of "platelet-derived" MP (PMP) in 13 patients before and after total body irradiation with 12 Gy (4 Gy for 3 days, dose rate 4.5 cGy/min). PMP were isolated and double-stained with annexin V and anti-CD61. In 6 patients, we additionally analyzed MP exposing P-selectin or CD63. RESULTS: PMP rapidly declined upon total body irradiation, which was 2.4-fold faster than platelet disappearance. In contrast, the kinetics of MP exposing P-selectin or CD63 was comparable to platelets. CONCLUSIONS: Since CD61-positive MP disappear faster than platelets or MP exposing P-selectin or CD63, our data indicate that MP exposing P-selectin or CD63 are likely to originate from platelets, whereas at least a major fraction of CD61-exposing MP is likely to originate from megakaryocytes in vivo.

Effects of a convenience drink fortified with n-3 fatty acids on the n-3 index.

There is strong evidence that the intake of EPA and DHA reduces the risk of adverse cardiac events. Fish and fish oil capsules are not necessarily an ideal source of EPA and DHA for every individual. The aim of the present study was to evaluate the effect of a convenience drink enriched with 500 mg EPA and DHA on the n-3 index, a biomarker of EPA and DHA status in an individual. Of the 190 subjects with atherosclerotic disease screened between February and June 2009, 50 were recruited based on an n-3 index < 5 %. Participants were randomly assigned to receive a convenience drink supplemented either with n-3 fatty acids (n 40, 200 mg EPA and 300 mg DHA) or placebo (n 10, 1.1 g linoleic acid, C18 : 2n-6, from maize oil) daily for 8 weeks. The primary end point was a change in the n-3 index. Intention-to-treat analysis was done. After 8 weeks of daily intake of 200 mg EPA+300 mg DHA, the mean n-3 index increased from 4.37 (sd 0.51) to 6.80 (sd 1.45) % (P < 0.001). Interindividual variability in response was high (CV of the Delta, cv = 0.21). The control group showed no change in the n-3 index. The results showed that daily intake of a convenience drink supplemented with n-3 fatty acids leads to a significant increase of the n-3 index with high interindividual variability in response. Dose and preparation used were safe, well tolerated and highly palatable.
