LDL-apheresis in acute anterior ischemic optic neuropathy

Acute anterior ischemic optic neuropathy (AION) is a disabling disease which impairs visual function. Standard treatment is unable to affect the outcome and the visual damage persists. We describe the case of a 64-year-old patient affected by AION, whose only known risk factor was hypercholesterolemia. After a first onset of involvement of the right eye (RE), the patient presented four weeks later with an analogous episode affecting the left eye (LE). Since standard treatment, started at involvement of the RE, had not yielded any beneficial effect, the patient underwent three sessions of LDL apheresis. The scotomatous portion of the visual field reduced even after the first session, there was further improvement after the third, and after six months the condition remained stable. Corrected vision improved from 2/10 to 6/10 after the third session. LDL cholesterol and fibrinogen decresade after the third session from 239 mg/dL to 31 mg/dL and from 289 mg/dL to 92 mg/dL, respectively. In conclusion, thanks to its effect of antagonizing hemorheologic disorders of the ocular microcirculation, LDL apheresis seems to be an efficacious treatment of AION, especially in patients suffering from hypercholesterolemia.     

Liposomal daunorubicin versus standard daunorubicin: long term follow-up of the GIMEMA GSI 103 AMLE randomized trial in patients older than 60 years with acute myelogenous leukaemia

This randomized phase III clinical trial explored the efficacy of DaunoXome (DNX) versus Daunorubicin (DNR) in acute myeloid leukaemia (AML) patients aged >60 years. Three hundred and one AML patients were randomized to receive DNR (45 mg/m(2) days 1-3) or DNX (80 mg/m(2) days 1-3) plus cytarabine (AraC; 100 mg/m(2) days 1-7). Patients in complete remission (CR) received a course of the same drugs as consolidation and then were randomized for maintenance with AraC+ all trans retinoic acid or no further treatment. Among 153 patients in the DNR arm, 78 (51.0%) achieved CR, 55 (35.9%) were resistant and 20 (13.1%) died during induction. Among 148 patients in the DNX arm, 73 (49.3%) achieved CR, 47 (31.8%) were resistant and 28 (18.9%) died during induction. Univariate analysis showed no difference as to induction results. After CR, DNX showed a higher incidence of early deaths (12.5% vs. 2.6% at 6 months, P = 0.053) but a lower incidence of relapse beyond 6 months (59% vs. 78% at 24 months, P = 0.064), with a cross in overall survival (OS) and disease-free survival (DFS) curves and a later advantage for DNX arm after 12 months from diagnosis. DNX seems to improve OS and DFS in the long-term follow-up, because of a reduction in late relapses.     

Liver frailty and all-cause mortality in the older participants of the Salus in Apulia Study

The liver contribution to the biological network underlying physical frailty in aging is underestimated. How best to measure this contribution magnitude and impact on health risk trajectories in frail individuals is not yet entirely clear. We analyzed the association of a novel liver frailty phenotype with the risk of death in older participants of the Salus in Apulia Study cohort. Clinical and physical examination, routine biomarkers, medical history, and anthropometry were analyzed in 1929 older adults (65?+). Physical frailty was classified by Cardiovascular Health Study criteria, and liver fibrosis risk by fibrosis-4 (FIB-4). The liver frailty phenotype was defined as physical frailty plus high-risk liver fibrosis (score?>?2.67). Physical frailty, high-risk liver fibrosis, and liver frailty subjects were compared to subjects without these conditions (non-frail). Proportional Cox regression tested the adjusted association between liver frailty and all-cause mortality for each category. The liver frailty prevalence was relatively low (3.8%), but higher in men (58.1%). Compared to non-frail older subjects, liver frailty subjects were significantly older (effect size (ES)???1.11, 95% confidence interval (CI)???1.35 to???0.87), with a lower education (ES 0.48, 95%CI 0.24 to 0.71) and higher multimorbidity (ES 15.81, 95%CI 4.20 to 27.41). Cox multivariate analyses showed a two-fold increased risk of overall mortality (hazard ratio 2.09, 95%CI 1.16–3.74) even after the adjustment for age, sex, education, and alcohol consumption. The liver frailty phenotype runs twice the risk of overall mortality compared with the non-frail population. This clinical tool, validated in a Southern Italian population, is based on simple sets of measures that can conveniently be assessed also in the primary care setting.

     

Photodynamic therapy with verteporfin for retinal angiomatous proliferation

Purpose The aim of this study was to evaluate the results of photodynamic therapy (PDT), using verteporfin, for subfoveal neovascular age-related macular degeneration (ARMD) with retinal angiomatous proliferation (RAP) with pigment epithelial detachment (PED) and/or choroidal neovascularization (CNV).Methods In this non-comparative, consecutive, interventional, case series, the data on 21 eyes (19 with stage 2 and two with stage 3 RAP) of 20 patients were reviewed. Serous PED occupied more than 50% of the lesion in 19 eyes. PDT was performed as per TAP protocol. Biomicroscopy and fluorescein and indocyanine-green angiography were performed to evaluate anatomical results and need for retreatment. Changes from baseline in best-corrected visual acuity (BCVA), and complications, were assessed.Results A mean of 3.5±0.9 treatments was performed. After 13.7±2.2 months, mean BCVA decreased from 20/80 to 20/174 (P=0.0063). In six eyes (28.6%) BCVA remained stable, whereas in 15 eyes (71.5%) it decreased. Occlusion of RAP and flattening of PED was observed in three (14.2%) eyes, conversion to disciform lesion in one (4.7%), and persistence of PED in 11 eyes (52.3%). One eye (4.7%) evolved to haemorrhagic PED, and one (4.7%) toward stage 3 RAP. A tear in the retinal pigment epithelium (RPE) was observed in four eyes (19%). Eleven (52.3%) showed progression of leakage, six moderate leakage (28.6%), and three (14.2%) absence of leakage.Conclusions Timely PDT with verteporfin in the early stages in eyes with smaller lesions has the potential for a beneficial effect on vision, whereas it might worsen the natural course of larger lesions, with most eyes undergoing enlargement, disciform transformation or RPE tear.Presented in part as a paper at the American Academy of Ophthalmology Annual Meeting, Anaheim, California, 15–18 November 2003The authors have no financial interest in this study     

Effect of cataract surgery and foldable intraocular lens implantation on retinal nerve fiber layer as measured by scanning laser polarimetry with variable corneal compensator

PURPOSE: Scanning laser polarimetry (SLP) enables the measurement of retinal nerve fiber layer (RNFL) thickness in vivo. As SLP measurements can be influenced by several conditions such as corneal birefringence, the new version GDx Access is implemented by the variable corneal compensator (VCC). The aim of this study was to evaluate the influence of cataract extraction and foldable intraocular lens (IOL) implantation on SLP parameters measured by GDx Access. METHODS: Sixty-eight eyes of 68 patients undergoing phacoemulsification with foldable IOL implantation (silicone and acrylic) were examined by SLP before and after surgery. SLP was performed using GDx Access (with VCC). Mean values for SLP parameters were compared before and after 30 days from surgery with paired two-tailed Student's t-test. RESULTS: No statistically significant differences were found between SLP parameters before and after cataract surgery, and regardless of the type of IOL implanted. CONCLUSIONS: Phacoemulsification and foldable IOL implantation do not influence RNFL parameters, as measured by GDx Access.     

Photodynamic therapy for retinal angiomatous proliferations and pigment epithelium detachment

PURPOSE: To evaluate results of photodynamic therapy (PDT) with verteporfin for subfoveal neovascular age-related macular degeneration (ARMD) with retinal angiomatous proliferation (RAP) and pigment epithelial detachment (PED). DESIGN: Interventional case series. METHODS: Thirteen eyes (11 stage 2 and 2 stage 3 RAP) underwent PDT. Best-corrected visual acuity (BCVA), fluorescein and indocyanine-green angiography were performed to evaluate the outcome. RESULTS: After 13.5 +/- 2.5 months and 1.7 +/- 0.4 treatments, mean BCVA decreased from 20/73 to 20/174 (P = .04). Occlusion of RAP and flattening of PED was observed in three eyes, and persistence of PED in six. Two eyes deteriorated to disciform lesions, one developed hemorrhagic PED, and one evolved toward stage 3 RAP. Three eyes, with PED exceeding 50% of the entire lesion, developed retinal pigment epithelium tear. CONCLUSIONS: PDT might prove effective for neovascular ARMD with RAP and small PED, whereas it might cause acute retinal pigment epithelium tear for RAP with PED exceeding 50% of the lesion.     

Luxated intraocular lens fixation using anterior chamber slipknot of the haptic to the sclera: a simple procedure to fixate intraocular lens to the sclera

PURPOSE: To describe a technique for suturing a luxated intraocular lens (IOL) in the vitreous cavity directly to the ciliary sulcus using intraocular slipknot without IOL extraction. DESIGN: Noncomparative interventional case series. MATERIALS AND METHODS: A three-port vitrectomy was performed in all cases. According to the Lewis procedure, two scleral flaps and relative sclerectomies were performed at 3 and 9 o'clock position. IOL was rescued from vitreous cavity by means of perfluorocarbon and stabilized in anterior chamber by intravitreal forceps. Corneal endothelium was preserved by a dispersive ophthalmic viscosurgical device coating. Double armed 10-0 polypropylene was introduced into the vitreous cavity through the 9 o'clock sclerotomy incision and both the needles were passed out of the eye by the 3-o'clock position sclerotomy, guided by a bent 27-gauge needle 1.5 mm from the limbus. Hooking the slipknot around the haptics of the IOL in the anterior chamber by means of vitreous forceps, the 10-0 polypropylene was pulled so that the IOL haptic was fixated onto the sulcus. The same procedure was used to fixate the opposite haptic to the ciliary sulcus at the opposite position. RESULTS: In all four cases, the IOL fixated stably and remained well positioned. No significant intraoperative or postoperative complications occurred. CONCLUSIONS: This technique enables secure fixation of the luxated IOL in the vitreous without extracting it.
