The association between duration of remission, fatigue, depression and health-related quality of life in Italian patients with systemic lupus erythematosus.

OBJECTIVE: To evaluate the impact of duration of remission on the health-related quality of life (HRQoL) of patients with systemic lupus erythematosus (SLE). METHODS: We conducted a 5-year retrospective study on two Italian cohorts. Remission was defined as a continuative period of no clinical disease activity, according to the Systemic Lupus Erythematosus Disease Activity Index 2 K, and a permitted maximum prednisone dose of 5 mg/day. HRQoL was measured using the 36-Item Short-Form Health Survey (SF36) during the last visit. RESULTS: We enrolled 136 female SLE patients. During observation, 15 (11%) patients had been in remission for ≥1 and <2 years, 15 (11%) for ≥2 and <3 years, 19 (14%) for ≥3 and <4 years, 9 (7%) for ≥4 and <5 years, and 53 (39%) had been in prolonged remission for ≥5 years. In the multivariate model, considering depression and fatigue as covariates, patients in prolonged remission showed significantly better scores in the physical functioning (p = 0.039), role physical (p = 0.029), bodily pain (p = 0.0057), general health (p = 0.0033) and social functioning (p = 0.0085) components of the SF36, compared with those in remission <5 years or unremitted. Subsequent mediation analyses found that these effects were partly influenced by depression. CONCLUSION: Lupus remission could improve the HRQoL of SLE patients, particularly when associated with appropriate management of depression and fatigue.

Psychological, emotional and social impairments are associated with adherence and healthcare spending in type 2 diabetic patients: an observational study.

OBJECTIVE: The aim of the present study was to assess the association among anxiety, depression, stress, social support and emotional abilities with adherence and healthcare spending in type 2 diabetic patients. PATIENTS AND METHODS: Sixty-four patients were enrolled and completed: Interpersonal Processes of Care (IPC), 20-item Toronto Alexithymia Scale (TAS-20), Rapid Stress Assessment Scale (RSAS), Morisky Medication Adherence Scale (MMAS-4), International Physical Activity Questionnaire (IPAQ)-Short Form and a socio-anamnestic questionnaire regarding also the healthcare spending. RESULTS: Mathematical linear regressions models were performed showing the predictive effects of: anxiety and social support scores (RSAS) on adherence levels (respectively p =. 019; p =. 016); adherence levels on anxiolytic use (p =.04); aggressiveness scores (RSAS) on the number of general check-ups (p =.031); TAS-20 and physician-patient communication (IPC) on the number of hospitalization days (respectively p=.001; p=.008); physician patient decision making (IPC) scores on physical activity (IPAQ) levels (p=.025); physical activity (IPAQ) on the number of medical examinations (p=.039). CONCLUSIONS: An association among psychosocial impairment, adherence and healthcare spending was found. Future studies should investigate the effect of a brief psychological intervention in increasing adherence levels and reducing the healthcare spending in this clinical population.

Health status and concomitant prescription of immunosuppressants are risk factors for hydroxychloroquine non-adherence in systemic lupus patients with prolonged inactive disease.

Background/objective The objectives of this paper are to assess the extent of and the factors associated with hydroxychloroquine (HCQ) non-adherence in systemic lupus erythematosus (SLE) patients with prolonged inactive disease and to investigate relationships between blood HCQ concentration and quality of life (QoL). Methods Consecutive SLE patients, in remission for at least one year and taking a stable dose of HCQ were investigated. At study entry (T0) and six months later (T6) a blood venous sample was taken to measure whole blood concentration of [HCQ] and desethylchloroquine ([DCQ]). Moreover, at T0 each patient completed validated questionnaires assessing QoL, disability, anxiety, depression and visual analogue scales for fatigue, pain, general health (GH), and self-assessment of disease activity. Results Eighty-three patients with a median [HCQ] of 327 ng/ml were enrolled. At T0, 24 (29%) were defined as non-adherent ([HCQ] < 100 ng/ml). At multiple logistic regression analysis the physical summary of SF-36 ( p = 0.038), and the concomitant use of immunosuppressants ( p = 0.010) were independently associated with non-adherence. A significant increase of HCQ adherence was observed at T6 ( p < 0.05). Conclusions A better health status and the concomitant prescription of immunosuppressants represent risk factors for HCQ non-adherence in SLE patients in remission. Monitoring HCQ levels might represent an important opportunity to improve adherence.

Primary prevention of cardiovascular disease in patients with systemic lupus erythematosus: case series and literature review.

Background Systemic lupus erythematosus is associated with an increased risk of cardiovascular disease. Low-dose aspirin, hydroxychloroquine and statins have been suggested to play a prophylactic role of cardiovascular events. This study is devoted to reviewing the literature on the topic and assessing the effects of these drugs in preventing a first cardiovascular event in a two-centre Italian series. Methods A PubMed search on cardiovascular prevention in systemic lupus erythematosus was performed. Moreover, systemic lupus erythematosus patients admitted to two centres from 2000-2015, who at admission had not experienced any cardiovascular event, were investigated. Aspirin, hydroxychloroquine and statin use, and the occurrence of any cardiovascular event, were recorded at each visit. Kaplan-Meier and Cox regression analyses were performed to evaluate the role of traditional, disease-related cardiovascular risk factors and of each of the three drugs in the occurrence of new cardiovascular events. Results The literature search produced conflicting results. Two hundred and ninety-one systemic lupus erythematosus patients were included in the study and followed for a median of eight years. During follow-up, 16 cardiovascular events occurred. At multivariate analysis, taking aspirin (hazard ratio: 0.24) and hydroxychloroquine for more than five years (hazard ratio: 0.27) reduced, while antiphospholipid antibody positivity (hazard ratio: 4.32) increased, the risk of a first cardiovascular event. No effect of statins emerged. Conclusion Our study confirms an additive role of aspirin and hydroxychloroquine in the primary prophylaxis of cardiovascular events in Italian patients with systemic lupus erythematosus. The lack of any detected effect in previous reports may depend on the design of studies and their short follow-up period.

Choroidal excavation in choroidal osteoma complicated by choroidal neovascularization.

PurposeTo describe multimodal imaging features of choroidal osteoma (CO) complicated by choroidal neovascularization (CNV) and focal choroidal excavation (FCE).MethodsPatients presenting with CO and CNV between January and October 2016 were considered for this study. Diagnosis of CO was confirmed by ultrasound examination. All patients underwent multimodal imaging including optical coherence tomography (OCT), swept-source OCT angiography (DRI OCT Triton, Topcon, Inc., Tokyo, Japan) and fluorescein angiography (Spectralis HRA+OCT; Heidelberg Engineering, Heidelberg, Germany).ResultsTwo patients (one with bilateral CO) were included in the study. OCT showed a FCE in two eyes of two patients (one in correspondence of the CNV and the other adjacent to the CNV). OCT-A demonstrated presence of microvascular flow within neovascular network of the CNVs. Decalcification of the tumor was noted in correspondence of one eye with FCE.ConclusionsFCE may be found in eyes with choroidal osteoma and CNV. OCT-A was a valuable tool for detection of CNV complicating choroidal osteoma. Decalcification of choroidal osteoma may represent a common pathogenic pathway for development of FCE and CNV in choroidal osteoma.

Optical Coherence Tomography Angiography of Diabetic Retinopathy.

PURPOSE: To describe the optical coherence tomography angiography (OCTA) features of diabetic retinopathy. METHODS: Literature review and case series. RESULTS: Four cases are presented. CONCLUSION: OCTA is an effective method for evaluating retinal changes in diabetic retinopathy and represents a novel complement or alternative to fluorescein angiography. Although OCTA should currently be considered an investigational technique, in the near future, it may play key roles in the diagnosis and management of diabetic retinopathy.

Management of atrial fibrillation in patients undergoing percutaneous coronary intervention.

Atrial fibrillation (AF) is the most common cardiac arrhythmia, occurring in 1-2% of overall population, involving more than 6 millions of European people. It is associated to a reduced quality of life and an increased morbidity and mortality. The Framingham study showed the link between angina and AF. The same risk factors, such as hypertension, diabetes and obesity promote both AF and coronary artery disease (CAD). About 1/4 of AF patients develop a CAD and, in this setting, about 1/5 undergoes a percutaneous coronary intervention (PCI). In patients with both AF and CAD, the optimal medical strategy is challenging and it is still debated in cardiological community, since patients treated by dual (two antiplatelets drugs ore one antiplatelets drug and an oral anticoagulant drug) or triple therapy (two antiplatelets drugs and an oral anticoagulant drug) are exposed to divergent risk of bleeding or thromboembolic and ischemic complications. Aim of this paper is to focus the attention on the different problems arising from the presence of AF in patients undergoing PCI, such as the risk of stroke, bleeding and stent thrombosis.

OCT-guided photodynamic therapy for angiographic occult CNV in pathologic myopia.

PURPOSE: Pathologic myopia (PM) is frequently complicated by choroidal neovascularization (CNV). Diagnosis is mainly clinical and angiographic but in recent years optical coherence tomography (OCT) has been noted to add important information. The authors report on the successfully OCT-guided photodynamic therapy (PDT) of an angiographic occult CNV complicating PM. METHODS: Observational case report. Fluorescein angiography with a confocal SLO (HRA, Heidelberg Engineering, Germany) and OCT Stratus (Carl Zeiss Meditec, Inc.) imaging were used for diagnosis and monitoring of the CNV. Standard PDT was performed. RESULTS: A highly myopic 17-year-old girl complained of a drop in visual acuity (VA) in left eye (LE), dating back a few weeks. Her best-corrected (BC) VA was 20/40 in the LE, with some metamorphopsia. No hemorrhage or evident signs of CNV were visible either at fundus or at dynamic fluorescein angiography. OCT scans indicated a slight elevation of the RPE-choriocapillary complex with rarefaction of neuroretinal tissue that has been interpreted as CNV. PDT was then performed. LE BCVA had improved to 20/25, metamorphopsias disappeared, and at OCT examination no retinal morphologic modification was evident. Nine months later, BCVA and ophthalmoscopy are still stable. CONCLUSIONS: In this case, OCT was the fundamental tool for the correct diagnosis and posttherapymonitoring of CNV-complicated PM. The CNV, not clearly detectable using angiographic imaging, was treated with PDT, and results in terms of VA and anatomic resolution were good.

Observation or surgical excision of bilateral subfoveal choroidal neovascularization in Best disease.

The purpose of this article is to describe a case of bilateral neovascularization complicating Best Disease. A 12-year-old patient with bilateral neovascularization was managed with observation in the right eye and surgical removal in the other eye. Visual acuity, biomicroscopy and fluorangiography were carried out from 1997 to 2005. The right eye did not experience any change in visual acuity from baseline (20/50) while left eye varied from 20/200 to 20/32. Macular exudative-hemorrhagic manifestations resolved bilaterally. Eight years later, VA and retinal findings were unchanged. In this case, although VA was reasonably good in both eyes, it is difficult to assess the prognosis of surgically excised neovascularization vs natural history, also considering that nowadays photodynamic therapy and antiangiogenetic drugs are considered the therapy of choice in subfoveal neovascularization.

Optical coherence tomography (OCT) in retinal angiomatous proliferation (RAP).

PURPOSE: To verify the utility of optical coherence tomography (OCT) for diagnosing retinal angiomatous proliferations (RAP) in patients with exudative age-related macular degeneration (AMD). METHODS: Multiple cross-sections were taken with OCT from 41 eyes of 39 consecutive patients with AMD and RAP. The presence and the location of the angiomatous complexes had already been documented by fluorescein angiography (FA) and high-speed confocal indocyanine green videoangiography (ICGA). RESULTS: RAP was detectable by OCT scans in all 41 eyes, appearing as a focal hyper-reflecting area in the neuroretinal layers; it was frequently located close to the inner surface of the retinal pigment epithelium (29 eyes [70.7%]). All eyes had either no or only a low-reflecting OCT signal surrounding the RAP, caused by serous intraretinal edema. Only 13 eyes (31.7%), however, had large serous retinal detachment (SRD). OCT detected pigment epithelium detachment in 31 eyes (75.6%), but none had underlying choroidal neovascularization. CONCLUSIONS: OCT findings confirm the intraretinal localization of the RAP which are always associated with impressive exudative phenomena. OCT is therefore a useful diagnostic tool, adding information to FA and high-speed ICGA. (Eur J Ophthalmol 2002; 12: 467-72).

Macular thickness measured by optical coherence tomography (OCT) in diabetic patients.

PURPOSE: 1) To compare macular thickness (MT) by optical coherence tomography (OCT) in diabetics and controls; 2) to assess the relationship between MT and stage of diabetic retinopathy (DR) and macular edema (ME); 3) to quantify MT changes after laser treatment for ME. METHODS: One-hundred and thirty-seven patients with diabetes mellitus (216 eyes) were admitted to the study and examined by stereo-color fundus photos, retinal fluorangiography and OCT. DR was classified as: 1) no DR (46 eyes: 21.3%); 2) background DR (66 eyes: 30.6%); 3) pre-proliferative DR (50 eyes: 23.1%); 4) proliferative DR (54 eyes: 25%). The study group was then divided into three ME groups: 1) no edema (65 eyes: 30.1%); 2) not clinically significant ME (no CSME) (45 eyes: 20.8%); 3) clinically significant macular edema (CSME) (106 eyes: 49.1%). Three-month follow-up tomograms were taken to evaluate eyes laser-treated only for ME. The control group consisted of 50 eyes of 50 non-diabetic, age- and sex-matched subjects. RESULTS: MT was 369.3 +/- 163.2 microm in diabetics and 161.9 +/- 12.9 microm in controls (p < 0.001). In the four DR groups it was: 1) 211.0 +/- 37.6 microm; 2) 370.8 +/- 159.6 microm; 3) 419.1 +/- 138.2 microm; 4) 456.1 +/- 162.0 microm (p<0.001). In the three ME groups, MT was: 1)227.8 +/- 53.4 microm; 2) 321.8 +/- 124.2 microm; 3) 476.2 +/-146.6 microm (p < 0.001). In the 52 eyes treated with laser photocoagulation of the posterior pole only and with a follow-up > 3 months, MT before and after treatment was 468.2 +/- 83. 17 microm and 372.1 +/- 120.63 microm. CONCLUSIONS: MT was greater in diabetics than controls and tended to increase with DR and ME severity. OCT is a sensitive technique for detecting early diabetic macular abnormalities and quantifying their reduction after laser treatment.

Optical coherence tomography (OCT) angiomatous prolifieration (RAP) in retinal.

PURPOSE: To verify the utility of optical coherence tomography (OCT) for diagnosing retinal angiomatous proliferations (RAP) in patients with exudative age-related macular degeneration (AMD). METHODS: Multiple cross-sections were taken with OCT from 41 eyes of 39 consecutive patients with AMD and RAP. The presence and the location of the angiomatous complexes had already been documented by fluorescein angiography (FA) and high-speed confocal indocyanine green videoangiography (ICGA). RESULTS: RAP was detectable by OCT scans in all 41 eyes, appearing as a focal hyper-reflecting area in the neuroretinal layers; it was frequently located close to the inner surface of the retinal pigment epithelium (29 eyes [70. 7%]). All eyes had either no or only a low-reflecting OCTsignal surrounding the RAP, caused by serous intraretinal edema. Only 13 eyes (31.7%), however, had large serous retinal detachment (SRD). OCT detected pigment epithelium detachment in 31 eyes (75.6%), but none had underlying choroidal neovascularization. CONCLUSIONS: OCT findings confirm the intraretinal localization of the RAP which are always associated with impressive exudative phenomena. OCT is therefore a useful diagnostic tool, adding information to FA and high-speed ICGA.

Choroidal calcifications in patients with Gitelman's syndrome.

Gitelman's syndrome is a renal tubular disorder characterized by a sodium and chloride reabsorption defect in distal tubular cells that determines hypokalemia, metabolic alkalosis, hypomagnesemia, and low calcium excretion. The presence of choroidal calcifications was sought in five patients with Gitelman's syndrome by ophthalmic examination, fluorescein angiography, indocyanine green angiography, and ocular ultrasonography. Calcifications observed in the choroid of two patients were shown by ultrasonography in both patients. Ophthalmic and fluorangiographic examinations detected this alteration in one of the two subjects. Chondrocalcinosis was found in one patient with choroidal calcifications. These findings suggest that precipitation of calcium salts can occur in the choroidal tissue of patients with Gitelman's syndrome. Deposits appeared to be well seen by ultrasonography because of their depth in ocular tissues. Sclerochoroidal calcifications may be favored by the low calcium excretion, which is associated with normal intestinal calcium absorption in patients with Gitelman's syndrome.

Unilateral macular retinoschisis with stellate foveal appearance in two females with myopia.

Stellate foveal retinoschisis is considered the hallmark of X-linked retinoschisis. We describe the finding of unilateral retinoschisis with stellate foveal appearance in 2 females with myopia who had no evidence of familial disease. Optical coherence tomography (OCT) and fluorescein angiography were obtained in both cases. Neither patient had a family history of low vision, night blindness, or retinal detachment. Visual acuity in the affected eyes was 20/50 and 20/25, respectively. Both fellow eyes had normal fundi, except for mild myopic changes. With OCT, widespread retinal splitting was detected at the posterior pole in the affected eyes, whereas the fellow eyes were normal. In one case, OCT showed that foveal retinoschisis represented the macular involvement of a flat inferior retinoschisis, although this was not clinically apparent. Macular retinoschisis with stellate foveal appearance may rarely be associated with pathologic myopia. OCT was useful to establish the true extension of these macular changes.

Axial length in patients with diabetes.

PURPOSE: To investigate the relationship between axial length and retinal involvement in patients with diabetes. METHODS: A total of 157 consecutive patients with diabetes underwent biometry. The patients were divided into three groups, according to retinopathy: 44 without retinopathy, 37 with background retinopathy, and 76 with proliferative retinopathy. To compare axial length in diabetic versus nondiabetic subjects, a control group of 157 healthy subjects with age and sex distribution similar to the diabetic group was selected from an orthopedic clinic. We investigated in the diabetic group whether the axial length was related to specific type of diabetes (non-insulin-dependent or insulin-dependent), duration of disease, presence of retinopathy, or laser treatment. To eliminate the confounding effect of myopia, we excluded all patients with axial length greater than 24 mm from the two groups. Comparison of diabetic patients without retinopathy versus nondiabetic subjects was also performed. RESULTS: Diabetic patients presented shorter axial lengths compared with the controls (mean +/- standard deviation, 22.4+/-1.3 mm versus 23.4+/-1.3 mm; P<0.001). Significantly shorter axial lengths were found in the background and proliferative retinopathy groups compared with the group without retinopathy (22.0+/-1.2 mm and 22.1+/-1.1 mm versus 23.2+/-1.4 mm, respectively; P<0.05). No difference in axial length was found between the diabetic patients without retinopathy and the nondiabetic subjects (P = 0.3). Multivariate analyses showed that retinopathy was negatively correlated with axial length (P<0.01). Including only the patients with axial length under 24 mm, we obtained similar results. CONCLUSION: Axial length is shorter in diabetic patients than in nondiabetic subjects. Within the diabetic group, patients with retinopathy had shorter axial lengths than did patients without retinopathy.

Optical coherence tomography in idiopathic epiretinal macular membrane surgery.

PURPOSE: To evaluate the usefulness of Optical Coherence Tomography (OCT) images for surgical indication, intraoperative management and postoperative outcome of patients with idiopathic epiretinal macular membrane (IEMM). METHODS: 28 selected eyes underwent surgery for removal of IEMM. The patients' mean age was 57.3 years. The macular region and the IEMMs were studied before and after surgery using OCT, slit-lamp biomicroscopy and fundus photography. The mean postoperative follow-up was 6.2 months (range 1.3-14). RESULTS: Preoperatively, in 12 of the 28 eyes (42.9%) only the OCT images revealed IEMM partially separated from the macula, with tractional focal point(s) of attachment to the macular region. In the other 16 eyes (57.1%) in which IEMMs were totally adherent to the macular region, the membranes were barely visible by OCT in 13 eyes and not visible in three. Intraoperatively, the surgeon was guided in the peeling procedures. A significant correlation (p < 0.001) was found between visual acuity and macular thickness before surgery and at the end of the postoperative follow-up. CONCLUSIONS: OCT images provide very useful information for the surgical indication, intraoperative management and postoperative outcome of patients with IEMM.

Ultrasound biomicroscopic evaluation of ciliochoroidal effusion after laser treatment.

We evaluated ciliochoroidal effusion (CE) by ultrasound biomicroscopy (UBM) following diode endophotocoagulation at the end of the vitreoretinal surgery. The aim of our study was to assess any differences in the CE morphology following diode endophotocoagulation or transpupillary krypton photocoagulation, and to demonstrate the influence of diabetes and intravitreal surgery on CE formation. Sixty-six consecutive patients were divided in to four groups. Twenty-nine patients with proliferative retinopathy underwent transpupillary krypton photocoagulation; 11 diabetic patients underwent vitreoretinal surgery and diode endophotocoagulation; 18 nondiabetics underwent vitreoretinal surgery and diode endophotocoagulation; 8 consecutive nondiabetic patients were the control group and underwent vitreoretinal surgery, without laser treatment. UBM was performed in the four groups before and after laser treatment, if performed. We determined, by UBM, not only the presence, but also the thickness of CE. CE was present in all the patients treated by laser, diabetics and nondiabetics, and its thickness was not correlated with the number of laser spots (p = 0.28). CE was seen ultrasonically in all the patients undergoing transpupillary photocoagulation or endophotocoagulation, regardless of diabetes and surgical trauma.

High-frequency ultrasound biomicroscopy versus ultrasound and optical pachymetry for the measurement of corneal thickness.

The aim of this study was to correlate central corneal thickness measurements obtained using optical as well as ultrasound pachymeters and high-frequency ultrasound biomicroscopy (UBM), assuming UBM as reference. Each measurement was performed on 32 patients (60 eyes) by three observers unaware of the other's results, on 3 different days. Pearson correlation was used. A strong correlation was found between UBM and ultrasound pachymetry measurements (r=0.858), a weaker one between UBM and optical pachymetry (r=0.506). Optical versus ultrasound measurements were poorly correlated (r=0.540). Each correlation was statistically significant (p<0.001). UBM can be used as an accurate and reproducible method for determining corneal thickness.

Extraocular muscle size comparison between normal and myopic eyes using standardized A scan echography.

The aim of this study was to establish the range of diameters of extraocular muscles in myopic patients and to obtain the baseline data to follow progression or regression of pathologies involving them. Standardized A scan and B scan ultrasound was used to measure the thickness of straight extraocular muscles at the muscle belly. No statistical differences were seen between right and left eyes. We found no consistent correlation with age or with axial length in the control or in the myopic patients (p>0.05). Diameters in myopic and control eyes were similar. This lack of difference between myopic and control muscle sizes means that we can obtain accurate measurements also from myopic patients.
