RESUMO

BACKGROUND: This study investigated whether directly measured small dense low-density lipoprotein cholesterol (D-sdLDL-C) can predict long-term coronary artery disease (CAD) events compared with low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B (apoB), and estimated small dense low-density lipoprotein cholesterol (E-sdLDL-C) determined by the Sampson equation in patients with stable CAD. METHODS: D-sdLDL-C measured at Showa University between 2010 and 2022, and E-sdLDL-C were evaluated in 790 male and 244 female patients with stable CAD. CAD events, defined as sudden cardiac death, onset of acute coronary syndrome, and/or need for coronary revascularization, were monitored for 12 years. Cutoff lipid levels were determined by receiver operating characteristic curves. RESULTS: CAD events were observed in 238 male and 67 female patients. The Kaplan-Meier event-free survival curves showed that patients with D-sdLDL-C ≥32.1 mg/dL (0.83 mmol/L) had an increased risk for CAD events (P = 0.007), whereas risk in patients with E-sdLDL-C ≥36.2 mg/dL (0.94 mmol/L) was not increased. In the group with high D-sdLDL-C, the multivariable-adjusted hazard ratio (HR) was 1.47 (95% CI, 1.15-1.89), and it remained significant after adjustment for LDL-C, non-HDL-C, or apoB and in patients treated with statins. HRs for high LDL-C, non-HDL-C, or apoB were not statistically significant after adjustment for high D-sdLDL-C. Higher D-sdLDL-C was associated with enhanced risk of high LDL-C, non-HDL-C, and apoB (HR 1.73; 95% CI, 1.27-2.37). CONCLUSIONS: Higher D-sdLDL-C can predict long-term recurrence of CAD in stable CAD patients independently of apoB and non-HDL-C. D-sdLDL-C is an independent risk enhancer for secondary CAD prevention, whereas E-sdLDL-C is not.UMIN-CTR Clinical Trial Number: UMIN000027504.

RESUMO

Purpose: An intraocular hemorrhage is an adverse event that can lead to visual acuity impairment. Antithrombotic therapy with antiplatelet agents and anticoagulants may increase intraocular hemorrhage. However, since their frequency is low, studies on the risk of intraocular hemorrhage with these drugs, especially under combination therapy, are limited. This study aimed to investigate the occurrence of intraocular hemorrhages under monotherapy and combination therapy with antiplatelets and anticoagulants by analyzing a large pharmacovigilance database. Methods: Intraocular hemorrhage signals with oral antiplatelets and anticoagulants were evaluated by calculating reporting odds ratios and information components using the Japan Adverse Drug Reactions Report database from April 2004 to March 2022. In addition, differences in signals between younger and elderly patients, affecting factors, and time-to-onset from initial antiplatelet and anticoagulant treatments were analyzed. Results: Aspirin, clopidogrel, warfarin, apixaban, and rivaroxaban, but not ticagrelor, ticlopidine, prasugrel, dabigatran, and edoxaban showed intraocular hemorrhage signals under monotherapy. In combination therapy, dual therapy (aspirin + P2Y12 inhibitors, warfarin, direct oral anticoagulants, and P2Y12 inhibitors + warfarin) and triple therapy (aspirin + P2Y12 inhibitors + warfarin) resulted in intraocular hemorrhage signals. Intraocular hemorrhage signals were observed in younger patients receiving monotherapy with aspirin and in elderly patients receiving monotherapy and combination therapy with warfarin. Affecting factors were diabetes mellitus in patients with prasugrel, use of medications for intravitreal injections, and posterior sub-Tenon injections with some antiplatelets and anticoagulants. The median period of intraocular hemorrhage occurrence after starting monotherapy with aspirin, clopidogrel, warfarin, or rivaroxaban was within 90 days. Conclusion: In addition to monotherapy with several antiplatelets and anticoagulants, combination therapy using aspirin, P2Y12 inhibitors, and warfarin has the potential risk of intraocular hemorrhage. Particular attention should be paid to the occurrence of intraocular hemorrhages in younger patients taking aspirin, in elderly patients taking warfarin, and within the first 90 days of antiplatelet and anticoagulant use.

RESUMO

PURPOSE: To assess the effects of half-dose photodynamic therapy (PDT) combined with an intravitreous aflibercept (IVA) injection for pachychoroid neovasculopathy (PNV) and its predictive factors. METHODS: Clinical information of 43 patients (43 eyes) with PNV obtained before and 6 months after treatment with half-dose PDT combined with IVA was retrospectively analyzed. Patients were categorized into the sufficient (25 eyes, 58.1%) or insufficient (18 eyes, 41.9%) group based on resolution or persistence/recurrence of subretinal fluid (SRF), respectively, and clinical data were compared. Macular neovascularization (MNV) change was studied in 30 cases with available pre- and post-treatment optical coherence tomography angiography images. RESULTS: The sufficient group included younger patients with better baseline best-corrected visual acuity (BCVA), more treatment-naïve eyes, and smaller MNV lesions at baseline than the insufficient group (all, P < 0.047). Complete SRF resolution was 81.8% in treatment-naïve eyes and only 33.3% in previously treated eyes. MNV expanded after half-dose PDT was combined with IVA regardless of the treatment outcome (P = 0.003). CONCLUSION: Half-dose PDT combined with IVA was effective for PNV treatment, especially for younger patients with good baseline BCVA, treatment-naïve eyes, and small MNV sizes at baseline. MNV expanded after treatment regardless of the treatment outcomes.

RESUMO

PURPOSE: To investigate the influence of an excess inverted internal limiting membrane (ILM) flap that covers the fovea in idiopathic macular hole surgery on postoperative visual acuity and macular morphology. METHODS: This retrospective study included 66 patients with an idiopathic macular hole who underwent vitrectomy using the inverted ILM flap technique. They were divided into three groups: normal morphology (N), detached ILM (D), or ILM proliferation (P) in the parafoveal area. They were followed up for at least 6 months, and their best-corrected visual acuity, central retinal thickness, and parafoveal retinal thickness were measured. RESULTS: There were no significant differences in preoperative or postoperative mean best-corrected visual acuities or postoperative CRTs among the groups. The postoperative inferior parafoveal retinal thicknesses were 319.2 ± 38.0, 377.1 ± 60.6, and 373.1 ± 67.3 µ m in the N, D, and P groups, respectively (P vs. D group, P = 0.963; P vs. N group, P = 0.008; N vs. D group, P = 0.004). CONCLUSION: Regardless of the postoperative morphology of the inverted ILM flap, there was no effect on postoperative best-corrected visual acuity or CRT.

RESUMO

PURPOSE: To examine the morphologic changes in macular neovascularization (MNV) secondary to age-related macular degeneration after 2 years of aflibercept treatment under a treat-and-extend (T&E) regimen. METHODS: This retrospective study analyzed the medical records for 26 eyes of 25 patients diagnosed with treatment-naive neovascular age-related macular degeneration and treated with aflibercept under a treat-and-extend regimen for 2 years. The areas of the MNV and vascular structures were assessed using swept-source optical coherence tomography angiography at baseline and after 2 years of treatment. RESULTS: The mean MNV area increased significantly from 0.65 ± 0.42 mm 2 at baseline to 0.78 ± 0.45 mm 2 at 2 years. At 2 years, the mean change in the MNV area from baseline was 22% (interquartile range: 4%-60%). The baseline MNV area was negatively correlated with the change ratio of the MNV areas at 2 years and baseline ( R = -0.68, P < 0.001). Nine of the 26 eyes (34.6%) showed newly formed mature vessels, and 7 eyes (26.9%) showed prominently developing preexisting mature vessels. CONCLUSION: Macular neovascularization expanded and showed vascular maturation under aflibercept treatment with a treat-and-extend regimen. The smaller the MNV at baseline, the greater is its expansion in 2 years.

RESUMO

PURPOSE: To determine the characteristics of eyes diagnosed with Best vitelliform macular dystrophy (BVMD) and autosomal recessive bestrophinopathy (ARB) complicated by choroidal neovascularization (CNV). METHODS: This was a retrospective, multicenter observational case series. Fourteen genetically confirmed BVMD patients and 9 ARB patients who had been examined in 2 ophthalmological institutions in Japan were studied. The findings in a series of ophthalmic examinations including B-scan optical coherence tomography (OCT) and OCT angiography (OCTA) were reviewed. RESULTS: CNV was identified in 5 eyes (17.9%) of BVMD patients and in 2 eyes (11.1%) of ARB patients. Three of 5 eyes with BVMD were classified as being at the vitelliruptive stage and 2 eyes at the atrophic stage. The CNV in 2 BVMD eyes were diagnosed as exudative because of acute visual acuity reduction, retinal hemorrhage, and intraretinal fluid, while the CNV in 3 BVMD eyes and 2 ARB eyes were diagnosed as non-exudative. The visual acuity of the two eyes with exudative CNV did not improve despite anti-VEGF treatments. None of the eyes with non-exudative CNV had a reduction of their visual acuity for at least 4 years. All of the CNV were located within hyperreflective materials which were detected in 16 eyes (57.1%) of the BVMD eyes and in 7 eyes (38.9%) of the ARB eyes. CONCLUSIONS: CNV is a relatively common complication in BEST1-related retinopathy in Asian population as well. The prognosis of eyes with exudative CNV is not always good, and OCTA can detect CNV in eyes possessing hyperreflective materials.

RESUMO

PURPOSE: To assess the effects of half-dose photodynamic therapy on subretinal fluid and macular neovascularization (MNV) using optical coherence tomography angiography in patients with chronic central serous chorioretinopathy. METHODS: Clinical information on 168 patients (168 eyes) with chronic central serous chorioretinopathy obtained before and 6 months after treatment with half-dose photodynamic therapy was retrospectively analyzed. Patients were categorized into a success (145 eyes) or failure (23 eyes) group based on the absence or presence of subretinal fluid, respectively, and clinical data were compared between them. Macular neovascularization was studied in 147 cases with available optical coherence tomography angiography images. P < 0.05 indicated statistical significance. RESULTS: The success group showed a younger patient age, better posttreatment best-corrected visual acuity, and thicker pretreatment central choroidal thickness (all, P < 0.047) than did the failure group. Regarding MNV analysis, nine, eight, and 130 eyes had definite, possible, and no MNV, respectively, at baseline; among them, 100.0%, 75.0%, and 2.3%, respectively, had MNV at 6 months posttreatment. Patients with definite MNV at baseline were less likely to show successful subretinal fluid resolution. CONCLUSION: Although half-dose photodynamic therapy is generally effective for the treatment of chronic central serous chorioretinopathy, coexisting MNV may compromise the outcome; thus, optical coherence tomography angiography-based assessment of chronic central serous chorioretinopathy is important.

RESUMO

PURPOSE: To investigate whether previously reported seasonal variation and winter-dominant prevalence of acute massive submacular hemorrhages (SMHs) caused by age-related macular degeneration (AMD) disappeared, and those caused by retinal microaneurysms (RMAs) emerged. METHOD: The medical charts of 95 patients (95 eyes) with SMH caused by AMD and 76 patients (76 eyes) with SMH caused by RMAs in 2012-2019 were retrospectively reviewed. For each subject, the month of onset, the mean ambient temperature of that month were recorded. RESULTS: The monthly numbers of cases of SMHs caused by AMD from January to December were 6, 8, 4, 9, 7, 10, 9, 11, 7, 11, 3, and 10. No significant seasonal variation in the monthly incidence was identified (Roger's R = 1.89, p = 0.39). The monthly numbers of SMHs caused by RMAs from January to December were 3, 11, 11, 8, 7, 8, 5, 5, 2, 4, 7, and 5. There was significant seasonal variation in the monthly incidence (Roger's R = 7.67, p = 0.02). There was no significant correlation between the monthly incidence of SMHs caused by RMAs and mean ambient temperature. CONCLUSION: Our previous study conducted for cases obtained in 1998-2005 showed seasonal cyclic trend in the number of SMHs caused by AMD, with the peak in winter. However, that significant seasonal variation disappeared in 2012-2019 in the present study. Common usage of OCT devices and anti-VEGF drugs might be the reason for the lack of seasonal variation in the cases of SMH caused by AMD.

RESUMO

PURPOSE: To describe the intraoperative and postoperative morphological and functional outcomes after autologous neurosensory retinal flap transplantation (ART) for a high myopia-related refractory macular hole (MH). METHODS: This prospective interventional study enrolled five eyes of five patients (age range 54-84 years) with highly myopic refractory MHs who underwent ART. All cases were evaluated with intraoperative optical coherence tomography and postoperative optical coherence tomography, optical coherence tomography angiography, and microperimetry for at least 6 months postoperatively. RESULTS: Intraoperatively, the MH was covered by an ART flap with a persistent small subretinal space that was filled with the ART flap after 4 days to 6 days. Optical coherence tomography discriminated the original from the transplanted retina. The mean basal diameter of the original MH decreased from 1,504 ± 684 µm preoperatively to 1,111 ± 356 µm postoperatively. The best-corrected visual acuity improved in two cases, was stable in two cases, and deteriorated in one case. Microperimetry demonstrated no obvious postoperative changes in the fixation points and the absolute scotoma corresponding to the base of MHs with chorioretinal atrophy. In two eyes, choroidal neovascularization developed beneath the transplanted retinas. CONCLUSION: Transplanted tissue was in a fixed position by 1 week postoperatively with a decreased diameter of the original MH. Postoperative fixation points were on the original retina at the MH edge. Because choroidal neovascularization may develop, detailed monitoring is required.

RESUMO

PURPOSE: To examine the characteristics of polypoidal choroidal vasculopathy using B-scan optical coherence tomography angiography (OCTA), and determine the diagnostic criteria of polypoidal choroidal vasculopathy based on OCTA. METHODS: This retrospective case series included patients diagnosed with treatment-naïve polypoidal choroidal vasculopathy who underwent indocyanine green angiography (ICGA) and swept-source OCTA at baseline. We compared the characteristics of the polyps detected using B-scan OCTA and ICGA. Then, the diagnostic concordance of each polypoidal lesion between ICGA and OCTA was evaluated. RESULTS: Among 54 eyes of 52 patients, all 54 eyes showed flow signals indicating polyps on both ICGA and B-scan OCTA. All polyps on B-scan OCTA were detected as round/ring-like flow signals inside pigment epithelial detachments, incomplete round/ring-like flow signals overlaid with round/ring-like OCT structures inside pigment epithelial detachments, or flow signals adjacent to a pigment epithelial detachment notch. Using B-scan OCTA, 94.7% of the polypoidal lesions were detected by an independent evaluator with an overall accuracy of 92.6% for counting the polypoidal lesions per eye relative to ICGA and a Kappa value of 0.82. CONCLUSION: Polyp detection on B-scan OCTA demonstrates high accuracy and is comparable to that obtained on ICGA. B-scan OCTA could replace ICGA for the diagnosis of polypoidal choroidal vasculopathy.

RESUMO

PURPOSE: To study B-scan flow overlay and en face flow optical coherence tomography angiography (OCT-A) images of Type 3 neovascularization (NV) and to characterize a staging system for Type 3 NV based on the OCT-A findings. METHODS: We retrospectively collected data on consecutive treatment-naive eyes with Type 3 NV. All eyes underwent fluorescein angiography, indocyanine green angiography, structural spectral domain OCT, and OCT-A (AngioPlex). Localization and extension of abnormal flows detected by B-scan flow overlay and en face OCT-A images were assessed. RESULTS: Of 24 eyes of 22 patients with Type 3 NV, B-scan flow overlay images showed that 4.2% had telangiectatic flow in the deep retinal layer without outer plexiform layer disruption (Stage 1), 8.3% had downward intraretinal flow and subretinal flow without retinal pigment epithelium disruption (Stage 2), and 87.5% had downward flow and retinal pigment epithelium disruption (Stage 3). Of the Stage 3 eyes, 95.2% showed flow signal penetrating at the site of the retinal pigment epithelium disruption on the B-scan flow overlay images. CONCLUSION: We showed the characteristics of Type 3 NV using B-scan flow overlay and en face OCT-A images. B-scan flow overlay OCT-A images seem useful to improve the detection and accurate diagnosis of Type 3 NV.

RESUMO

PURPOSE: To assess the morphological changes of cone photoreceptors in eyes with autosomal recessive bestrophinopathy. METHODS: Both eyes of five patients with autosomal recessive bestrophinopathyunderwent spectral domain optical coherence tomography and adaptive optics fundus imaging. The cone photoreceptor densities were measured at intervals of 100 µm between 500 µm nasal and temporal eccentricities from the foveal center. RESULTS: The median age of the patients was 30 years (range, 23-45 years), and the best-corrected visual acuity ranged from 20/20 to 20/80. Adaptive optics fundus images showed reduced cone photoreceptor densities corresponding to the damages of the photoreceptor layer in the spectral domain optical coherence tomography images in four patients with relatively good best-corrected visual acuity. The cone photoreceptor densities at the center of the fovea were less than one-third of the normal cone densities (range 11,600-30,400 cells/mm). Cone photoreceptor mosaics were visible over the lesions with serous retinal detachment and retinal edema, although they were partially hyporeflective. CONCLUSION: There is a significant cone photoreceptor loss in the macular region of patients with autosomal recessive bestrophinopathy, although they had relatively good visual acuity. Monitoring cone photoreceptors by adaptive optics fundus imaging should provide accurate assessments of the disease status and indications for future therapeutic interventions.

RESUMO

BACKGROUND: Previously, we showed that serum malondialdehyde (MDA) was significantly higher in patients with neovascular age-related macular degeneration (nAMD) than in those without AMD. The Diacron reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) tests are known markers of oxidative stress. The aim of this study was to use d-ROMs and BAP tests to evaluate changes in systemic oxidative stress in patients with nAMD. METHODS: Blood serum samples were collected from 34 patients with nAMD (mean age: 76.5 ± 7.7 years; 22 men) and 20 control subjects (mean age: 62.9 ± 14.0 years; 10 men), and d-ROMs and BAP tests were examined. RESULTS: In men, the mean level of d-ROMs for the nAMD patients was significantly higher than that for the controls (312.0 ± 52.4 vs. 275.1 ± 45.5 U.CARR, respectively; P < .05). There was a significant correlation between d-ROM level and CNV lesion area in the male nAMD group (r = .42, P = .05). There were no significant differences in mean BAP test results between the nAMD patients and controls for either sex (men: 2241 ± 549 vs. 2136 ± 246 µmol/L; women: 2263 ± 292 vs. 2335 ± 161 µmol/L). CONCLUSION: The d-ROMs test may provide a useful indicator of nAMD in men but not in women.

RESUMO

PURPOSE: The internal limiting membrane (ILM), the innermost basement membrane of the retina, is peeled occasionally during vitreous surgery. This study aimed to investigate the effect of ILM loss on the retina. METHODS: We used optical coherence tomography to retrospectively evaluate retinal changes in 26 eyes (11 ILM-peeled and 15 ILM-unpeeled eyes) of 26 patients after vitrectomy for retinal detachment. In addition, we studied six eyes of three patients with Alport syndrome, in which ILM is genetically impaired. RESULTS: We observed significant inner retinal displacement of the foveal pit toward the optic disk with inner retinal thickening in the nasal area (fellow, 191.9 ± 24.3 µm vs. affected, 210.3 ± 31.4 µm; P = 0.048), inner retinal thinning in the temporal area (fellow, 174.3 ± 18.3 µm vs. affected, 142.2 ± 23.6 µm; P < 0.001), foveal thickening (ILM-unpeeled, 217.0 ± 39.4 µm vs. ILM-peeled, 302.0 ± 86.2 µm; P = 0.006), inner retinal dimples predominantly in the temporal area, and deviation between the foveal pit and foveal bulge. Eyes with Alport syndrome exhibited similar findings. CONCLUSION: Internal limiting membrane loss seems to cause characteristic inner retinal changes of the macula in both congenital and acquired conditions.

RESUMO

PURPOSE: To examine the characteristics of the foveal vascular structure of patients with retinopathy of prematurity (ROP) by optical coherence tomography angiography. METHODS: Ten patients with a history of laser photocoagulation or cryopexy treatment for Stage 3 (Zone ≥ II) ROP and 10 normal subjects (controls) were included. Foveal avascular zone, vessel density, vessel length, and vascular diameter index were measured by optical coherence tomography angiography using the 3 × 3-mm Early Treatment Diabetic Retinopathy Study (ETDRS) sectors. RESULTS: The median foveal avascular zone values of the patients with ROP and controls were 0.103 mm and 0.260 mm, respectively (P = 0.0025). The medians of the vessel density, vessel length, and vascular diameter index of the patients with ROP were 0.218 mm/mm, 11.75 mm/mm, and 18.00 µm, respectively, in ETDRS Sector 1 and did not significantly differ from those of the controls (P = 0.940, 0.733, and 0.705, respectively). For the average of ETDRS Sectors 2 to 5, the medians of the vessel density, vessel length, and vascular diameter index for the patients with ROP were 0.347 mm/mm, 18.95 mm/mm, and 18.28 µm, respectively; vessel density and vessel length were significantly smaller than those of the controls (P = 0.002 and 0.003, respectively), but there was no significant difference in vascular diameter index (P = 0.286). CONCLUSION: Optical coherence tomography angiography-guided foveal avascular zone was significantly smaller in patients with ROP than in controls. Our results indicate that foveal vascular development may be altered in patients with a history of treatment-requiring ROP.

RESUMO

PURPOSE: To assess predictive factors and surgical outcomes for myopic traction maculopathy. METHODS: This retrospective observational case study enrolled 73 patients who underwent vitrectomy for myopic traction maculopathy. The 79 eyes obtained from our study sample were divided into 4 types: retinoschisis, lamellar macular hole (lamellar MH), foveal retinal detachment (FRD), and FRD + lamellar MH, or into 2 types according to the presence of FRD preoperatively. Dependent variables of interest were age, sex, pre- and postoperative best-corrected visual acuity (BCVA) at 6 months, and axial length. RESULTS: All the four types showed moderately strong-to-strong positive correlations with pre- and postoperative BCVA (retinochisisi: r = 0.61; lamellar MH: r = 0.62; FRD: r = 0.51; FRD + lamellar MH; r = 0.83). Preoperative BCVA was associated with postoperative BCVA (P < 0.0001), but age, axial length, and the types of preoperative foveal status were not. Eyes with FRD had significantly worse pre- and postoperative BCVA than eyes without FRD (P = 0.036 and P = 0.046, respectively). Postoperative full-thickness macular holes developed in 5.1% of cases and in all types but retinoschisis. CONCLUSION: Preoperative visual acuity and the presence of FRD should be considered for surgical indication of myopic traction maculopathy.

RESUMO

PURPOSE: To determine the prognosis of eyes with central retinal vein occlusion that had a preserved foveal depression at the baseline and were treated by intravitreal ranibizumab injections (IRIs). METHODS: The authors reviewed the medical records of 23 eyes of 23 consecutive treatment-naive patients who received IRIs to treat the macular edema due to central retinal vein occlusion. Eyes were classified by the pre-IRI presence or absence of a foveal depression. A foveal depression was defined as a central foveal thickness that was <50 µm thinner than the average thickness at 200 µm temporal and nasal to the central fovea. The characteristics of the two groups were compared. RESULTS: Seven of 23 eyes had a preserved foveal depression before the IRI. The mean number of injections within 12 months after the initial IRI was significantly fewer (P < 0.001) in eyes with foveal depression (1.6 ± 0.5) than in eyes without foveal depression (4.3 ± 1.3). The mean best-corrected visual acuity at 12 months after the initial IRI was significantly better (P = 0.003) in eyes with foveal depression (0.10 ± 0.17 logarithm of the minimum angle of resolution [logMAR] units; 20/25 Snellen units) than in eyes without foveal depression (0.77 ± 0.54 logMAR units; 20/118 Snellen units). CONCLUSION: These results indicate that the prognosis is better for eyes with a foveal depression before the IRI treatment for a macular edema secondary to central retinal vein occlusion.

RESUMO

PURPOSE: To investigate the microvascular changes in choroidal neovascularization (CNV) using optical coherence tomography angiography (OCTA) during anti-vascular endothelial growth factor (VEGF) therapies. METHODS: We retrospectively collected data on consecutive treatment-naïve eyes with typical age-related macular degeneration that initially received 3 aflibercept injections. OCTA was performed at baseline and at 1, 2, and 4 months of follow-up. The CNV images were analyzed using open-source software to assess vessel area and junction density. RESULTS: Fifteen eyes of 15 patients were included. The mean vessel area at baseline was 0.50 ± 0.33 mm2; at 1, 2, and 4 months, the ratios of change in vessel area from baseline were 66.6 ± 38.8%, 80.5 ± 25.5%, and 94.0 ± 29.3%, respectively. The vessel area was significantly reduced at 1 month from that at baseline (p = 0.0015) but significantly increased at 4 months from that at 1 month (p = 0.011). The mean junction density was also significantly reduced from 4.70 ± 1.30/mm at baseline to 3.82 ± 1.06/mm at 1 month (p = 0.00084). However, junction density did not continue to decrease at 2 and 4 months. CONCLUSION: OCTA quantification revealed that CNV rebounded after repeat aflibercept injections despite shrinking in response to the first injection.

RESUMO

Following publication of the original article [1], the authors identified a number of errors. In Result (P.3), Table 1 (P.4), Table 5 (P.9) and Supplementary Table 1, the correct unit for adiponectin was µg/mL. In Table 1 (P.4), the correct value for the post treatment body weight in dapagliflozin was 76.2±14.8. In Table 6 (P.10), the correct value for the pre treatment sd LDL/LDL-C in decreased LDL-C group was 0.38±0.10.

RESUMO

BACKGROUND: The sodium-glucose co-transporter-2 (SGLT-2) inhibitors have been reported to increase both low-density lipoprotein (LDL) and high-density lipoprotein (HDL)-cholesterol (C). This study aimed to determine how SGLT-2 inhibitors affect LDL and HDL-C subspecies. METHODS: This single center, open-label, randomized, prospective study included 80 patients with type 2 diabetes taking prescribed oral hypoglycemic agents. Patients were allocated to receive dapagliflozin (n = 40) or sitagliptin (n = 40) as add-on treatment. Fasting blood samples were collected before and 12 weeks after this intervention. Small dense (sd) LDL-C, large buoyant (lb) LDL-C, HDL2-C, and HDL3-C levels were determined using our established homogeneous assays. Statistical comparison of blood parameters before and after treatment was performed using the paired t test. RESULTS: Dapagliflozin and sitagliptin comparably decreased HbA1c (0.75 and 0.63%, respectively). Dapagliflozin significantly decreased body weight, systolic blood pressure, plasma triglycerides and liver transaminases, and increased adiponectin; sitagliptin did not alter these measurements. LDL-C and apolipoprotein (apo) B were not significantly changed by dapagliflozin, whereas HDL-C and apo AI were increased. Dapagliflozin did not alter concentrations of LDL-C, but sd LDL-C decreased by 20% and lb LDL-C increased by 18%. Marked elevation in lb LDL-C (53%) was observed in individuals (n = 20) whose LDL-C was elevated by dapagliflozin. However, sd LDL-C remained suppressed (20%). Dapagliflozin increased HDL2-C by 18% without affecting HDL3-C. Sitagliptin did not alter plasma lipids or lipoprotein subspecies. CONCLUSIONS: A SGLT-2 inhibitor, dapagliflozin suppresses potent atherogenic sd LDL-C and increased HDL2-C, a favorable cardiometabolic marker. Although LDL-C levels are elevated by treatment with dapagliflozin, this was due to increased concentrations of the less atherogenic lb LDL-C. However, these findings were not observed after treatment with dipeptidyl peptidase-4 inhibitor, sitagliptin. Trial registration UMIN Clinical Trials Registry (UMIN000020984).
