[Retinal vascular network: Changes with aging and systemic vascular disease (cardiac and cerebral)]

For over 10 years, the description of the retinal microvascular network has benefited from the development of new imaging techniques. Automated retinal image analysis software, as well as OCT angiography (OCT-A), are able to highlight subtle, early changes in the retinal vascular network thanks to a large amount of microvascular quantitative data. The challenge of current research is to demonstrate the association between these microvascular changes, the systemic vascular aging process, and cerebrovascular and cardiovascular disease. Indeed, a pathophysiological continuum exists between retinal microvascular changes and systemic vascular diseases. In the Montrachet study, we found that a suboptimal retinal vascular network, as identified by the Singapore I Vessel Assessment (SIVA) software, was significantly associated with treated diabetes and an increased risk of cardiovascular mortality. In addition, we supplemented our research on the retinal vascular network with the use of OCT-A. In the EYE-MI study, we showed the potential role of quantitative characterization of the retinal microvascular network by OCT-A in order to assess the cardiovascular risk profile of patients with a history of myocardial infarction. A high AHA (American Heart Association) risk score was associated with low retinal vascular density independently of hemodynamic changes. Thus, a better understanding of the association between the retinal microvasculature and macrovascular disease might make its use conceivable for early identification of at-risk patients and to suggest a personalized program of preventative care. The retinal vascular network could therefore represent an indicator of systemic vascular disease as well as an interesting predictive biomarker for vascular events.

[BCG strain shortage from 2012 to 2014: Evaluation of its impact on the management of patients with high-risk NMIBC]

INTRODUCTION

BCG instillations are the gold-standard treatment for high-risk non-muscle-invasive bladder cancer (NMIBC) with a decreased risk of tumor recurrence and muscle infiltration. From 2012 to 2014, a stock shortage of the Connaught strain has led to the cessation of supply for immucyst in France. The objective of this study was to evaluate the potential impact of BCG shortage on the management of patients with NMIBC.

PATIENTS AND METHODS

We conducted a retrospective single-center study including patients followed from May 2005 to May 2015 with a high-risk NMIBC (primo-diagnosis). Patients were separated into two groups: not impacted by the shortage (NISG: 56 patients) and impacted by the shortage (ISG: 53 patients). Data on tumour recurrence (RFS), muscle progression (PFS) and overall and specific survival (OS and SS) were also analysed.

RESULTS

The BCG induction schedule could not be carried out in 20.8% of cases in the ISG compared to only 5.3% of cases in NISG (P=0.02). Similarly, the maintenance treatment was incomplete for 56.6% of cases versus 37.5% in NISG (P=0.047). Nevertheless, it should be underlined that very high-risk NMIBC received a complete induction BCG schedule. The ISG seems to have benefited with the evolution of the guidelines with the use of diagnosis bladder fluorescence but without significant difference on the rate of second look bladder trans-uretral resection. The cystectomy rate was higher in ISG. No significant difference in RFS, PFS, OS, and SS between the two groups.

CONCLUSION

In our experience, RFS, PFS, OS or SS were not impacted by the BCG shortage. These data may be explained by a better selection of very high-risk patients including the recommended BCG schedule and more frequently the use of diagnosis bladder fluorescence.

Serum fructosamine predicts macrosomia in well-controlled hyperglycaemic pregnant women: An observational cross-sectional study

AIM

While serum fructosamine may be a good marker of glucose control in pregnant women with diabetes, its relationship with macrosomia is still uncertain.

METHODS

In 130 hyperglycaemic women with singleton pregnancies (117 gestational diabetes mellitus, 13 pregestational diabetes), serum fructosamine and HbA1c levels were measured at 25±7 weeks of gestation. Levels in mothers of infants with and without macrosomic newborns (birth weight>4000g and/or large-for-gestational-age birth weight>90th percentile) were compared using logistic regression analysis adjusted for macrosomia risk factors.

RESULTS

These 130 pregnant women were 33±5 years old; their BMI before pregnancy was 27.7±6.9kg/m², and they gained 7.5±5.1kg during the first 6 months of gestation. Glucose control was good according to HbA1c levels (5.3±0.3%; 34±2mmol/mol), yet 17/130 (13%) newborns had macrosomia: 3900±227g vs 3057±512g (P<0.001) in the others. These mothers were older and had higher parity, whereas their BMI scores before pregnancy and gestational weight gains did not differ. Fructosamine levels were also higher at 221±40μmol/L vs 192±22μmol/l (P<0.001), respectively, and remained significant even after adjusting for maternal age, BMI, parity, type of diabetes, antecedents of macrosomia and excessive gestational weight gain. By contrast, HbA1c did not differ between the two groups. In fact, nearly two-thirds (64.7%) of the mothers of macrosomic newborns had fructosamine levels>200μmol/l vs 31.9% of mothers with non-macrosomic newborns (P<0.05).

CONCLUSION

High fructosamine levels are associated with macrosomia in the newborns of well-controlled hyperglycaemic pregnant women.

The association of vision loss and dimensions of depression over 12 years in older adults: Findings from the Three City study

BACKGROUND

The established relationship between vision impairment and depression is limited by the examination of depression only as a unidimensional construct. The present study explores the vision-depression relationship using a dimensional approach.

METHODS

9036 participants aged 65 years and above enrolled in the Three-City study were included. Relationships between baseline near Vision Impairment (VI) or self-reported distance Visual Function (VF) loss with trajectory of four dimensions of depression - depressed affect, positive affect, somatic symptoms and interpersonal problems - over 12 years were examined using mixed-effects models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD).

RESULTS

In the fully adjustment models, mild near VI predicted poorer depressed affect (b = 0.04, p = .002) and positive affect (b = -0.06, p < 0.001) over time, with evidence of longer term adjustment. Distance VF loss was associated with poorer depressed affect (b = 0.27, p ≤ .001), positive affect (b = -0.15, p = .002), and somatic symptoms (b = 0.18, p ≤ .001) at baseline, although only the association with depressed affect was significant longitudinally (b = 0.01, p = .001). Neither near VI nor distance VF loss was associated with interpersonal problems.

LIMITATIONS

This paper uses a well-supported model of depression dimensions, however, there remains no definite depression dimension model. Distance VF loss was self-reported, which can be influenced by depression symptoms.

CONCLUSIONS

Vision impairment in older adults is primarily associated with affective dimensions of depression. A reduction in social connectedness and ability to engage in pleasurable activities may underlie the depression-vision relationship. Older adults with vision impairment may benefit from targeted treatment of affective symptoms, and pleasant event scheduling.

Bidirectional associations of vision and hearing loss with anxiety: prospective findings from the Three-City Study

OBJECTIVE

the aim of this study was to examine the bidirectional association of vision loss (VL) and hearing loss (HL) with anxiety over a 12-year period.

DESIGN

this was a prospective population-based study.

SETTING

community-dwelling French adults.

PARTICIPANTS

the study included 3,928 adults aged 65 and above from the Three-City study.

METHODS

the relationships of VL, as assessed by near visual acuity and self-reported HL to a diagnosis of generalised anxiety disorder (GAD) were assessed over 12 years. A further objective was to explore whether sensory loss has a differential relationship with GAD than with anxiety symptoms, assessed by the Spielberger's State-Trait Anxiety Inventory.

RESULTS

at baseline, HL [odds ratio (OR) = 1.41, 95% confidence interval (CI) 1.02-1.96, P = 0.04], but not mild or moderate to severe VL, was associated with self-reported anxiety symptoms (OR = 1.07 95% CI 0.63-1.83, P = 0.80; OR = 0.66 95% CI 0.12-2.22, P = 0.50, respectively). Neither vision nor HL was significantly associated with incident GAD. Baseline GAD was related to increased risk of incident HL (OR = 1.17, 95% CI 1.07-1.28, P < 0.001), but not mild or moderate to severe vision loss (OR = 1.01, 95% CI 0.96-1.06, P = 0.81; OR = 0.97, 95% CI 0.89-1.05, P = 0.45, respectively).

CONCLUSIONS

increased anxiety symptoms were observed in older adults with HL, whereas we found no evidence for an association between VL and anxiety. Anxiety was prospectively associated with increased risk of reporting HL. Improved detection of anxiety in older adults with HL may improve quality of life.

Skin autofluorescence predicts major adverse cardiovascular events in patients with type 1 diabetes: a 7-year follow-up study

Background

Advanced glycation end-products play a role in diabetic vascular complications. Their optical properties allow to estimate their accumulation in tissues by measuring the skin autofluorescence (SAF). We searched for an association between SAF and major adverse cardiovascular events (MACE) incidence in subjects with Type 1 Diabetes (T1D) during a 7 year follow-up.

Methods

During year 2009, 232 subjects with T1D were included. SAF measurement, clinical [age, sex, body mass index (BMI), comorbidities] and biological data (HbA1C, blood lipids, renal parameters) were recorded. MACE (myocardial infarction, stroke, lower extremity amputation or a revascularization procedure) were registered at visits in the center or by phone call to general practitioners until 2016.

Results

The participants were mainly men (59.5%), 51.5 ± 16.7 years old, with BMI 25.0 ± 4.1 kg/m², diabetes duration 21.5 ± 13.6 years, HbA1C 7.6 ± 1.1%. LDL cholesterol was 1.04 ± 0.29 g/L, estimated Glomerular Filtration Rates (CKD-EPI): 86.3 ± 26.6 ml/min/1.73 m². Among these subjects, 25.1% were smokers, 45.3% had arterial hypertension, 15.9% had elevated AER (≥ 30 mg/24 h), and 9.9% subjects had a history of previous MACE. From 2009 to 2016, 22 patients had at least one new MACE: 6 myocardial infarctions, 1 lower limb amputation, 15 revascularization procedures. Their SAF was 2.63 ± 0.73 arbitrary units (AU) vs 2.08 ± 0.54 for other patients (p = 0.002). Using Cox-model, after adjustment for age (as the scale time), sex, diabetes duration, BMI, hypertension, smoking status, albumin excretion rates, statin treatment and a previous history of MACE, higher baseline levels of SAF were significantly associated with an increased risk of MACE during follow-up (HR = 4.13 [1.30–13.07]; p = 0.02 for 1 AU of SAF) and Kaplan–Meier curve follow-up showed significantly more frequent MACE in group with SAF upper the median (p = 0.001).

Conclusion

A high SAF predicts MACE in patients with T1D.

The association amongst visual, hearing, and dual sensory loss with depression and anxiety over 6 years: The Tromsø Study

OBJECTIVE

To examine the longitudinal association of dual and single (vision and hearing) sensory loss on symptoms of depression and anxiety in older adults.

METHODS

Two thousand eight hundred ninety adults aged 60 years or over who participated in the longitudinal population-based Tromsø Study, Norway, were included. The impact of objective vision loss, self-report hearing loss, or dual sensory loss on symptoms of depression and anxiety, as assessed by the Hopkins Symptom Checklist 10, was examined at baseline and 6-year follow-up using linear mixed models.

RESULTS

Hearing loss had a cross-sectional relationship with increased depression (b = 0.1750, SE = 0.07, P = .02) and anxiety symptoms (b = 0.1765, SE = 0.08, P = .03); however, these relationships were not significant at the 6-year follow-up. Both vision loss only and dual sensory loss predicted increased depression scores at follow-up (b = 0.0220, SE = 0.01, P = .03; and b = 0.0413, SE = 0.02, P = .01, respectively). Adjustment for social isolation did not attenuate the main depression results.

CONCLUSION

Dual sensory loss resulted in increased depression symptomatology over time and posed an additional long-term risk to depression severity beyond having a single sensory loss only. Only hearing loss is associated with anxiety symptoms. Older adults with vision, hearing, and dual sensory loss have different mental health profiles. Therefore, management and intervention should be tailored to the type of sensory loss.

The role of mineral metabolism and inflammation on dialysis vascular access failure

Thrombosis of arteriovenous fistula (AVF) is the leading cause of vascular access (VA) loss usually due to silent stenosis. Therefore, assessment of relevant risk factors of VA monitoring may provide insight into potential therapeutic targets for stenosis and thrombosis. The aim of this study was to evaluate the influence of cardiovascular risk factors (including inflammation and mineral metabolism dysfunctions) on the failure of internal AVF in HD patients.

128 HD patients with internal AVF were included in the study and followed up for two years. At baseline, VA morphology and function were followed by Doppler ultrasonography and serum albumin, prealbumine, C-reactive protein, orosomucoid, calcium, phosphorus, parathyroid hormone, bone-type alkaline phosphatase, osteoprotegerin and receptor activator of nuclear factor κB ligand were measured.

At baseline, 50 stenoses were detected but none of them required any intervention. Age and biological parameters did not significantly differ between patients with or without VA stenosis. Over the two year- follow up, VA thrombosis occurred in 19 patients. Preexisting stenosis of VA was present in 9/19 patients (47.3% of cases) (chi-square = 3.708, p = 0.0538). Despite the low rate of events, phosphorus [1.75 (0.95–2.77) vs 1.42 (0.47–3.22) mmol/L, p = 0.0416], Calcium x Phosphorus product [4.00 (2.00–5.90) vs 3.40 (1.10–6.80) mmol2/L2, p = 0.0676] and parathyroid hormone [165.00 (1.00–944.00) vs 79.50 (1.00–846.60) ng/L, p = 0.0814) levels were higher in the 19 thrombotic patients whereas all other biological parameters did not significantly differ.

These results, which confirm that VA thrombosis occurs more frequently upon preexisting stenosis, also demonstrate that mineral metabolism disorders, compared to inflammation, may contribute to VA dysfunction leading to thrombosis.

Urethral pressure controlled balloon refilling or balloon change for artificial sphincter secondary procedure?

OBJECTIVES

To report our experience of inflating or changing pressure balloon to treat recurrent urinary incontinence after AMS800^® implantation instead of changing all the devices.

PATIENTS AND METHODS

A retrospective study was conducted in a tertiary reference center between 2005 and 2015. All patients, treated by AMS800^® implantation for post-prostatectomy urinary incontinence and whom balloon was subsequently changed or inflated, were included. Main clinical end point was the need for another surgery. Secondary end points were urethral erosion, infection, and efficacy on pad test and pad use.

RESULTS

Thirty-one patients were included. All had had a 61-70cm H₂0 balloon implanted, with a single cuff (13 with transcorporeal placement). Twenty-one patients had their balloon changed for a 71-80cm H₂0 type, while 10 patients had their balloon refilled (median 3mL [range 2-7]). Median follow-up was 23 months (range 1-129). Overall rate of another subsequent surgery was 48.3% (n=15). Erosion and atrophy occurred more frequently after balloon repressurizing than after balloon replacement (80% vs 33%, P=0.024). At last follow-up, median pad use was higher in repressurizing group (2 vs 1, P=0.033).

CONCLUSION

Balloon repressurizing is associated with a higher erosion and reoperation rate than changing pressure balloon. Continence results seem better when PRB is changed. It could be an alternative instead of changing all devices in patients with frail urethra.

Sequential treatment with ProACT™ device implantation after male sling failure for male urinary incontinence

OBJECTIVES

There is no strong evidence for second line therapy after male sling failure for post-prostatectomy urinary incontinence (PPUI). We report the outcomes after periurethral balloons implantation for persistence or recurrence of mild PPI symptoms after male sling implantation.

METHODS

All patients implanted of a ProACT™ device (Uromedica, Inc., MN, USA) following I-STOP transobturator male sling (TOMS) failure, in a tertiary reference center between 2009 and 2016, were included. Patients were evaluated by 24-hour pad-test before and after implantation, and after each balloon repressurizing procedure. PGI-I and Likert scale patient satisfaction were estimated during a telephone interview conducted in 2016. Objective and subjective cure of urinary incontinence were defined by a 24-hour pad-test<8g and the use of zero or one pad per day, respectively.

RESULTS

Fourteen patients were included. Median follow-up was 34months [4-89]. Objective and subjective cure were 29% (n=4) and 57% (n=8), respectively. Median pad-test decreased from 95g [IQR: 130] to 34g [IQR: 83] (P=0.022). ProACT™ significantly decreased median pad-test by a factor 2.73 [1.19-6.29]. Eighty-eight percent patients were feeling a little better, much better or very much better and 77% were satisfied or very satisfied at the end of follow-up. Reoperation rate was 28% (n=4): 3 balloons were changed for caudally migration (n=2) or deflation (n=1) and 1 had a urinary sphincter implanted for severe UI.

CONCLUSIONS

ProACT™ is a safe and efficient treatment that can be used in second line therapy after TOMS failure for PPUI.

[HoLEP learning curve: Toward a standardised formation and a team strategy]

AIM

Holmium laser enucleation of prostate (HoLEP) is renowned for the difficulty of its learning curve. Our aim was to evaluate the interest of a three-step tutorial in the HoLEP learning curve, in a university center.

METHODS

It is a retrospective, monocentric study of the 82 first procedures done consecutively by the same operator with a proctoring in early experience and after 40 procedures. For all patients were noted: enucleation efficiency (g/min), morcellation efficiency (g/min), percentage of enucleated tissue (enucleated tissue/adenome weigth evaluated by ultrasonography. g/g), perioperative morbidity (Clavien), length of hospital stay, length of urinary drainage, functional outcomes at short and middle term (Qmax, post-void residual volume [PVR], QOL scores and IPSS at 3 and 6months).

RESULTS

Enucleation and morcellation efficiency were significantly higher after the second proctoring (0.87 vs 0.44g/min; P<0.0001 and 4.2 vs 3.37g/min, P=0.038, respectively) so as the prostatic volume (43.5 vs 68.1mL, P=0.0001). Percentage of enucleated tissue was higher in the second group, however, the difference was not significant (69.5% vs 80.4%, P=0.03). Per- and postoperative complications, hospital length of stay, urinary drainage length and functional results at 3 and 6months were not significantly different.

CONCLUSION

The learning curve did not interfere with functional results. The second proctoring was essential to us in order to grasp the technique. These data underlined the necessity of a pedagogic reflexion in order to built a standardized formation technique to the HoLEP.

[External sphincterotomy in neurological patients: A monocentric experience]

AIM

The aim of this study was to assess the feasibility, efficacy and tolerance of Greenlight™ and Holmium sphincterotomy for treating detrusor-sphincter dyssynergia.

METHODS

All men treated with this two techniques between may 2012 and june 2015 were analyzed. Preoperative evaluation included kidney ultrasound scan, urodynamic, retrograde and voiding urethrocystography. Postoperative assessment was composed of a post-void residual volume measurement when the urethral catheter was removed and 1 year after the procedure, a retrograde and voiding urethrocystography at 3 months and telephonic Likert scale questionnaire.

RESULTS

Twelve patients were operated with Greenlight™ and 12 with Holmium. Eleven had a memocath urethral stent preoperatively. Post-void residual volume median for both techniques was 285 cc preoperatively vs 137.5 cc postoperatively (P<0.001). Likert scale global satisfaction was 75%. Five stenosis (20.8%) were observed within a median of 4 months.

CONCLUSION

Greenligth™ and Holmium procedures are efficient techniques with low morbidity. However, superiority toward monopolar incision remains to be demonstrated through complementary studies.

Abstract 180: The Relation of Timing and Degree of Blood Pressure Control with Hematoma Growth - Secondary Analysis of The Interact2 Trial

Background: Acute blood pressure (BP) lowering therapy has shown clinical benefit in patients with acute intracerebral hemorrhage (ICH), but the effect of timing and degree of BP control on ICH growth has received less study.

Methods: Among the INTERACT2 participants (N=2839) with acute ICH allocated either to intensive BP lowering therapy (IT, systolic target <140mmHg) or standard BP treatment (ST), CT brain imaging at baseline and 24 hours were centrally analysed in a subset of 491 (34%) in the IT and 473 (34%) in the ST groups.

Results: Absolute mean ICH growth was lower in patients reaching BP target in <1h from randomization (1.7ml), as compared to those reaching target in 1-6h (4.2ml), and >6h (4.6ml, p=0.04). Hematoma growth was particularly high (14.4ml, 95%CI:10.0-18.8) in patients admitted with systolic BP>160mmHg who achieved <10mmHg systolic BP lowering over 24h, as compared to those achieving 10-20mmHg (3.7ml, 95%CI:0.3-7.1) or 20-30mmHg BP reduction (2.7ml, 95%CI:1.1-4.3); p<0.01). Patients maintaining target BP at 0-2 measurements over 24h had higher absolute volume increase (3.6ml; 95%CI:1.8-5.4) as compared to those who maintained target BP over 3-4 (1.6ml, 95%CI:-0.3-3.5), or 5-8 measurements (0.4ml, 95%CI:-1.7-2.4; p=0.01).

Conclusion: These findings suggest that early and sustained BP control have favorable effects on hematoma growth. This reinforces the principle for patients with acute ICH to receive BP lowering therapy as early as possible and to achieve a lower level of systolic BP for the most favorable outcome.

Nutrition and age-related eye diseases: the Alienor (Antioxydants, Lipides Essentiels, Nutrition et maladies OculaiRes) Study

BACKGROUND

Worldwide, degenerative eye diseases (age-related maculopathy (ARM), cataract, glaucoma) are the main causes of visual impairment and blindness, which contribute to disability in the elderly. Mainly three types of nutritional factors are investigated for their potential protection against eye ageing: antioxidants; lutein and zeaxanthin (carotenoids which accumulate specifically in the eye); omega 3 polyunsaturated fatty acids. Few epidemiological studies have been conducted in this field, particularly in Europe.

OBJECTIVE

The Alienor (Antioxydants, Lipides Essentiels, Nutrition et maladies OculaiRes) Study aims at assessing the associations of eye diseases with nutritional factors, determined from plasma measurements and estimation of dietary intakes.

DESIGN, SETTING AND PARTICIPANTS

Subjects were recruited in Bordeaux (France) from the ongoing population-based 3C study. In 2006-2008, 963 subjects from the 3C Study, aged 73 years or more, had an eye examination and will have follow-up eye examinations every 2 years.

MEASUREMENTS

Vascular, genetic and nutritional factors were assessed at baseline (1999-2001) and follow-up examinations of the 3C Study. Eye diseases were classified according to international classifications.

RESULTS

Nutritional status and vascular disease and risk factors were similar between participants and non participants, except for a slight difference in plasma triglycerides and HDL-cholesterol. As expected, the prevalence of eye diseases was high: early and late ARM (28.4 % and 5.6 %, respectively), open-angle glaucoma and treated ocular hypertension (4.8 % and 10.0 %, respectively), cataract extraction (45.2 %), retinopathy (8.4 %), retinal vein occlusion (1.1 %), epiretinal membrane (3.9 %), current use of artificial tears (17.3 %).

CONCLUSIONS

This study confirms the high prevalence of eye diseases in the elderly. Its main strength is the combination of nutritional, vascular and genetic information, collected over a 7 year period of time before the first eye examination. It may help design future interventional studies, which might be common with other age-related disorders, because of common nutritional factors.

The Second (Main) Phase of an Open, Randomised, Multicentre Study to Investigate the Effectiveness of an Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (Interact2)

Rationale:

The INTERACT pilot study demonstrated the feasibility of the protocol, safety of early intensive blood pressure lowering and effects on haematoma expansion within 6h of onset of intracerebral haemorrhage. This article describes the design of the second, main phase, INTERACT2.

Aims:

To compare the effects of a management strategy of early intensive blood pressure lowering with a more conservative guideline-based blood pressure management policy in patients with acute intracerebral hemorrhage.

Design:

INTERACT2 is a prospective, randomized, open label, assessor-blinded end-point (PROBE). Patients with a systolic blood pressure greater than 150 mmHg and no definite indication for or contraindication to blood pressure-lowering treatment are centrally randomised to either of two treatment groups within 6h onset of intracerebral haemorrhage. Those allocated to intensive blood pressure lowering will receive primarily intravenous, hypotensive agents to achieve a systolic blood pressure target of <140 mmHg within 1 h of randomisation and to maintain this level for up to 7 days in hospital. The control group will receive blood pressure-lowering treatment to a target systolic blood pressure of < 180 mmHg. Both groups are to receive similar acute stroke unit care, therapy and active management. Oral antihypertensive therapy is recommended in patients before hospital discharge with a long-term systolic blood pressure goal of 140 mmHg according to secondary stroke prevention guidelines. A projected 2800 subjects are to be enrolled from approximately 140 centres worldwide to provide 90% power (α 0·05) to detect a 14% difference in the risk of death and dependency between the groups, which equates to one or more cases of a poor outcome prevented in every 15 patients treated.

Study outcomes:

The primary outcome is the combined end-point of death and dependency according to the modified Rankin Scale at 90 days. The secondary outcomes are the separate components of the primary end-point in patients treated <4 hours of ICH onset, grades of physical function on the modified Rankin Scale, health-related quality of life on the EuroQoL, recurrent stroke and other vascular events, days of hospitalisation, requirement for permanent residential care and unexpected serious adverse events. The study is registered under NCT00716079, ISRCTN73916115 and ACTRN12608000362392.

Waist Circumference Adds to the Variance in Plasma C-Reactive Protein Levels in Elderly Patients with Metabolic Syndrome

BACKGROUND

C-reactive protein (CRP), a nonspecific marker of the inflammatory status, is associated with cardiovascular disease risk factors and may be an important feature of the metabolic syndrome (MSX) in middle-aged subjects.

OBJECTIVES

We assessed the relationship of CRP levels to specific components of MSX and other potential determinants in apparently healthy elderly subjects living in the South of France.

METHODS

In the framework of the population-based POLA (Pathologies Oculaires Liées à l'Age) Study, performed in 2,404 subjects aged 60 years or more, we measured the plasma CRP levels. All subjects with known systemic inflammatory diseases, such as chronic bronchitis, cardiovascular disease, and diabetes, and those who were on systemic steroid therapy as well as subjects with CRP levels >10 mg/l were excluded from the study, leaving 1,709 subjects for the statistical analyses. MSX was defined according to NCEP (National Cholesterol Education Program) criteria. Other potential determinants were assessed through interviewer-based questionnaire.

RESULTS

We grouped the subjects into three categories based on the 75th and 25th percentiles, corresponding to 3.05 and 0.82, respectively. We compared subjects in the highest quartile, i.e., with CRP >/=3.05 mg/l, with those in the two intermediate quartiles, i.e., with 0.82 < CRP < 3.05, and those in the lowest quartile, i.e., with CRP <0.82 mg/l according to gender. MSX, which had a prevalence of 31%, was significantly associated with elevated CRP levels. Among MSX components, the strongest positive association with the highest quartile of CRP was with waist circumference in males as well as in females (age-adjusted odds ratio OR 3.06 and 95% confidence interval CI 1.82-5.14; OR 7.04 and 95% CI 4.79-10.34, respectively). Each component of the MSX, such as abnormal fasting plasma glucose (OR 2.90, 95% CI 1.69-4.99), triglycerides (OR 1.96, 95% CI 1.30-2.96), high-density lipoprotein cholesterol (OR 2.31, 95% CI 1.61-3.30), and blood pressure (OR 1.66, 95% CI 1.12-2.45), was significantly associated with high CRP values in elderly women only. In men, only current smoking was significantly associated with high CRP levels (OR 1.52, 95% CI 1.04-2.2). In multivariate analysis, the waist circumference remained significantly associated with high CRP levels, with a graded effect of CRP quartile whatever the gender. In men, current and former smoking remained significantly associated with the CRP levels. In women, the association observed in univariate analysis with fasting glucose or hypertension did not reach statistical significance in the multivariate analysis, while only a weak association could be observed with lipid parameters such as triglycerides and high-density lipoprotein cholesterol.

CONCLUSIONS

Abdominal adiposity adds to the variance in plasma CRP levels in elderly patients with MSX. This suggests that weight loss or other interventions targeted at adipocyte-related inflammation may represent an important means to prevent subclinical inflammation in the elderly, bearing a high risk of cardiovascular disease.

Types of choroidal neovascularisation in newly diagnosed exudative age-related macular degeneration

AIM

To describe the types and location of choroidal neovascularisation (CNV) in exudative age-related macular degeneration (AMD), including vascularised pigment epithelial detatchments (PED), and most recently described subtypes, such as retinal choroidal anasmostosis, also termed "retinal angiomatous proliferation" (RAP).

METHODS

Prospective multicentre consecutive descriptive case series. A total of 207 consecutive cases of newly diagnosed exudative AMD undergoing fluorescein angiography (FA) were recruited by 7 French referral hospital-based or private centres. Indocyanine green angiography (ICG) also was performed, when judged necessary by investigators. Types and location of CNV were classified by two independent experts and adjudicated by a third when discordant.

RESULTS

All patients had FA, while ICG was performed in 50% of subjects. A total of 17.6% had classic CNV only, 5.4% and 8.3% had predominantly and minimally classic CNV, respectively. Occult CNV could be classified in occult CNV without PED (32.7%) and occult CNV with PED, ie, vascularised PED (23.9%). RAP was observed in 15.1% of cases, and accounted for 30% of vascularised PED. In 5.8% of the cases there was haemorrhagic AMD and 4.8% had fibrovascular scars. Lesions were mainly subfoveal (80%). Agreement between the centre's ophthalmologist and the final validated expert classification was moderate (kappa = 0.52 for location and 0.59 for type of lesion).

CONCLUSION

This study confirms that newly diagnosed cases of exudative AMD are mainly occult and subfoveal. RAP appeared as a common lesion in patients with newly diagnosed exudative AMD.

Dietary fat and the risk of age-related maculopathy: the POLANUT study

This study aimed at assessing the associations of dietary fat with the risk of age-related maculopathy (ARM), in the framework of a population-based study from southern France. Nutritional data were collected using a dietitian-administered food-frequency questionnaire. ARM was classified from retinal photographs using the international classification and included neovascular age-related macular degeneration, geographic atrophy, soft indistinct drusen, soft distinct drusen associated with pigmentary abnormalities. After multivariate adjustment, high total, saturated and monounsaturated fat intake were associated with increased risk for ARM (odds ratio (OR)=4.74, P=0.007; OR=2.70, P=0.04; and OR= 3.50, P=0.03, respectively). Total polyunsaturated fatty acid was not significantly associated with ARM. Total and white fish intake was not significantly associated with ARM, but fatty fish intake (more than once a month versus less than once a month) was associated with a 60% reduction in risk for ARM (OR=0.42, P=0.01).
