Long-term outcome in corneal endotheliitis with molecular detection of herpes simplex virus 1 and human herpes virus 6: a case report.

BACKGROUND: Human herpesvirus 6B (HHV-6B) is known to cause exanthema subitem and has been detected in various ocular diseases, including keratitis, uveitis, optic neuritis, and endophthalmitis; however, the long-term outcome after the reactivation of HHV-6B has not been well-addressed. Sugita et al. previously reported the concomitant presence of HHV-6B with herpes simplex virus-1 (HSV-1) in the aqueous fluid at the onset of corneal endotheliitis. We focused on the same patient with corneal endotheliitis, in whom both HSV-1 and HHV-6B sequences were observed, and reported the clinical course and long-term outcomes. CASE PRESENTATION: A 64-year-old woman was referred to our center for visual disturbances in the left eye. Her best-corrected visual acuity in the left eye was 0.5 and the left intraocular pressure was elevated to 33 mmHg. Mid-sized keratic precipitates and 2+ cells were observed in the anterior chamber with corneal endothelial edema and reduction of the corneal endothelial cell density to 1828 cells/mm2. The patient was diagnosed with corneal endotheliitis with increased intraocular pressure. Polymerase chain reaction analysis revealed the concomitant presence of both HSV-1 and HHV-6B sequences in the left aqueous fluid. After treatment with oral valacyclovir and topical betamethasone, her intraocular inflammation gradually improved and has not recurred at 12 years after corneal endotheliitis onset although corneal opacity remained. CONCLUSIONS: Reactivation of HHV-6B infection might be associated with HSV-1 corneal endotheliitis; however, no serious late sequelae occurred after appropriate treatment for HSV-1 infection in this immunocompetent host.

Long-Term Clinical and Angiographic Outcomes After Implantation of New-Generation Drug-Eluting Stents for Patients on Maintenance Hemodialysis.

Prior research has revealed poorer clinical outcomes after drug-eluting stent (DES) implantation for hemodialysis patients. This study aims to investigate the long-term clinical and angiographic outcomes after new-generation DES implantation for hemodialysis patients.We retrospectively enrolled 91 consecutive patients (118 lesions) who underwent successful new-generation DES (everolimus-, zotarolimus-, and biolimus-eluting stents) implantation for the first time. We measured the serum calcium and phosphorus levels in the blood samples obtained just before hemodialysis. The follow-up period of clinical events was, at least, 1.5 years. In this study, major adverse cardiac and cerebrovascular events (MACCE) and clinically driven target lesion revascularization were reported in 36 (39.6%) and 11 (12.1%) patients, respectively. The prevalence of peripheral artery disease was significantly higher in the MACCE group (41.7% versus 14.5%, P = 0.006). The serum calcium level was significantly higher in the MACCE group (9.34 ± 0.92 mg/dL versus 8.77 ± 0.88 mg/dL; P = 0.004). The multivariate Cox proportional hazards model revealed that the serum calcium level (hazard ratio, 1.86; 95% confidence interval [CI]: 1.26-2.77; P = 0.002), suboptimal (over 55 mg2/dL2) calcium-phosphorus product (hazard ratio, 3.27; 95% CI: 1.41-7.61; P = 0.006) and the coexistence of peripheral artery disease (hazard ratio, 3.15; 95% CI: 1.49-6.65; P = 0.003) were independent predictors of MACCE.For hemodialysis patients, MACCE remains a frequent occurrence after new-generation DES implantation and is associated with calcium-phosphate metabolism and peripheral artery disease.

Acquired myopia in Vogt-Koyanagi-Harada disease.

PURPOSE: To analyze the change in refractive error and the axial length of chronic Vogt-Koyanagi-Harada (VKH) disease. METHODS: Medical records of 106 eyes of 54 adult VKH patients were analyzed. The refractive error and the axial length were compared between the baseline (defined as the time point at least 2 weeks after acute stage of VKH) and the final visit. The rate of the eyes with significant myopia progression [defined as refraction change toward myopia > 1 diopter (D)] was examined. The correlation of the degree of sunset glow fundus/choroidal thickness with the change in refractive error was also evaluated. RESULTS: At the final visit, the mean refractive error was more myopic and the axial length was longer than at baseline. Seventeen of the 106 eyes (16.0%) showed significant myopia progression. The mean change in refractive error during a follow-up in these 17 eyes was - 2.7 D (range - 7.5 to - 1.1 D). The axial length data both at baseline and at the final visit were obtained only in 8 eyes. The mean change in axial length during a follow-up in these 8 eyes was 1.3 mm (range 0-3.7 mm). In the cases with myopia progression, sunset glow fundus was more frequent and subfoveal choroid was thinner than those without myopia progression. CONCLUSIONS: Myopia progression as well as increase in axial length occurs in VKH disease. The link between choroidal thinning and axial length elongation in VKH patients gives some insights into axial length increase of pathologic myopia.

[The anti-inflammatory effect of 0.1% bromfenac and 0.1% betamethasone combination in post-cataract surgery patients with diabetes mellitus].

PURPOSE: To compare the post cataract surgery anti-inflammatory effect of bromfenac monotherapy and of bromfenac and betamethasone combination therapy in diabetes mellitus patients. METHODS: A prospective study approved by the Institutional Review Board. Fifty-one eyes of 51 patients were randomly allocated to either bromfenac 0.1% monotherapy (n = 23) or combined therapy with bromfenac 0.1% and betamethasone 0.1% (n = 28). After surgery, monotherapy group was administered bromfenac alone for 8 weeks, while the combined therapy group was administered both bromfenac and betamethasone for 2 weeks, bromfenac alone for the next 6 weeks. The amount of change from preoperative values in anterior chamber flare and foveal thickness were compared between the 2 groups. RESULTS: There was no significant difference in change in anterior chamber flare between the 2 groups. The increase in foveal thickness 4 weeks postoperatively was significantly larger in the bromfenac group (p = 0.0356). Four patients of the bromfenac group, all with a history of diabetic macular edema, developed macular edema after surgery. CONCLUSION: Bromfenac and betamethasone combination exhibited a stronger anti-inflammatory effect after cataract surgery patients with diabetes mellitus. In particular, patients with a history of diabetic macular edema were susceptible to foveal thickening and macular edema, and a combined treatment is desirable.

Human T-cell Leukemia Virus Type 1 (HTLV-1)-induced Uveitis.

Human T-cell leukemia virus type 1 (HTLV-1) is a human retrovirus that causes T-cell malignant diseases (adult T-cell leukemia/lymphoma) and HTLV-1-related non-malignant inflammatory diseases, such as HTLV-1 uveitis. Although the symptoms and signs of HTLV-1 uveitis are nonspecific, intermediate uveitis with various degrees of vitreous opacity is the most common clinical presentation. It can occur in one or both eyes and its onset is acute or subacute. Intraocular inflammation can be managed with topical and/or systemic corticosteroids; however, recurrence of uveitis is common. The visual prognosis is generally favorable, but a certain proportion of patients have a poor visual prognosis. Systemic complications of patients with HTLV-1 uveitis include Graves' disease and HTLV-1-associated myelopathy/tropical spastic paraparesis. This review describes the clinical characteristics, diagnosis, ocular manifestations, management, and immunopathogenic mechanisms of HTLV-1 uveitis.

Perceived Future Outcomes of Unsuccessful Treatment and Their Association with Treatment Persistence Among Type-2 Diabetes Patients: A Cross-Sectional Content Analysis.

INTRODUCTION: Despite the known strong association between patients' knowledge of outcomes of type 2 diabetes mellitus (T2DM) and treatment persistence, this knowledge in this patient population requires further clarification. The aim of our study was to reveal the perception of unsuccessful treatment outcomes among patients with T2DM and its association with treatment persistence by analysing answers to open-ended questions. METHODS: In this cross-sectional study, 106 patients with T2DM who lived in Fukushima Prefecture, Japan, had a medical record in the Fukushima National Health Insurance Organisation database and had no cognitive problems were enrolled by purposive sampling. Treatment status was defined as "non-persistent" when a participant's treatment medical record was absent for a continuous period of ≥ 6 months; otherwise, it was referred to as "persistent". We asked about the possible future problems of untreated T2DM, inductively classified the open answers into 15 codes and then statistically examined the association between these codes and treatment persistence using logistic regression analysis adjusted for age and sex. RESULTS: Persistent treatment was prevalent among participants who mentioned the code "treatment", which encompasses the terms that indicated invasiveness, such as dialysis, insulin injection, and shots (odds ratio 4.339; 95% confidence interval 1.104-17.055). CONCLUSION: Persistent treatment was prevalent among patients with T2DM who mentioned the code "treatment", suggesting that these patients may anticipate a threat due to the invasiveness of diabetes and thus participate in persistent treatment to avoid this threat. Healthcare professionals should provide appropriate information and supportive conditions to achieve both a reduced feeling of threat and persistent treatment engagement.

Corneal Toxicity After Stinging by a Sea Anemone, Anthopleura uchidai: A Case Report With Confirmation by In Vitro Study.

PURPOSE: This study aimed to present a case of transient corneal damage after exposure to the effluent squirting from a sea anemone, Anthopleura uchidai, and to experimentally confirm the presence of toxic substances from an A. uchidai in the tissue culture. METHODS: We reviewed the clinical course of a 51-year-old man who complained of decreased vision in his left eye after the stinging of a sea anemone, A. uchidai. The toxicity of the effluents from an A. uchidai in immortalized human corneal endothelial cells (HCEnC-21T) and human corneal epithelial cells in vitro were evaluated. RESULTS: Corneal edema was observed, and his best-corrected visual acuity was 0.2. Corneal endothelial cell density decreased to 1435 cells/mm2. Although his corneal edema and visual acuity recovered after topical instillation with a topical steroid and 5% NaCl, corneal endothelial cell density did not recover for 3 years after the injury. The in vitro study revealed fractioned effluence from the sea anemone, by size-exclusion chromatography, containing a substance toxic to HCEnC-21T with cytoplasmic swelling and nuclear dislocation. CONCLUSIONS: It is necessary to be cautious of effluents from sea anemones along the coast, and ophthalmologists should be aware that sea anemones can cause corneal endothelial dysfunction.

Qualitative and Quantitative Study on Components of Future Time Perspective and Their Association with Persistent Treatment for Type 2 Diabetes.

INTRODUCTION: Future time perspective (FTP) means the capacity to foresee, anticipate, and plan for future desired outcomes, and it contributes to persistent treatment for type 2 diabetes mellitus (T2DM). However, the components of FTP specific to T2DM patients have not been clarified. This study aimed to explore the components of FTP and to examine the associations between such components and persistent/impersistent diabetes treatment. METHODS: In this cross-sectional study, using qualitative and quantitative methods, 106 T2DM patients were enrolled by purposive sampling. The participants were interviewed in October and November 2018 by public health nurses in Koriyama City Public Health Center, Japan. In addition to the participants' status of treatment engagement (persistent/impersistent), their responses regarding reasons for persistent/impersistent treatment were collected and then summarized into nine subthemes, which were then merged into two main themes according to the presence or absence of FTP with a sense of T2DM ownership for analysis. RESULTS: The main theme, "presence of FTP with a sense of T2DM ownership," included subthemes such as "securing social independence," "planning on living a long and healthy life," "prioritizing avoiding being a burden on family and friends," "valuing improvement of diabetes," "avoiding tragic results," "optimistically viewing treatment as a form of self-development," and "improving mental health," whereas the main theme, "absence of FTP with a sense of T2DM ownership," included "lack of consciousness of disease" and "living a dissipated life." The association between the presence of FTP with a sense of T2DM ownership and persistent treatment for T2DM was found using Fisher's exact test (p < 0.001). CONCLUSION: Health care professionals should support T2DM patients in having an FTP with a sense of T2DM ownership and purpose in life instead of treatment goals when such patients mention their dissipated life or lack of insight into the disease.

Distinguishing Features of Anterior Uveitis Caused by Herpes Simplex Virus, Varicella-Zoster Virus, and Cytomegalovirus.

PURPOSE: To determine distinguishing features of the clinical characteristics of anterior uveitis (AU) caused by herpes simplex virus (HSV), varicella-zoster virus (VZV), and cytomegalovirus (CMV). DESIGN: Retrospective, multicenter case series. METHODS: Consecutive patients with herpetic AU examined at 11 tertiary centers in Japan between January 2012 and December 2017 and who were followed for ≥3 months were evaluated. Diagnosis was made by polymerase chain reaction (PCR) for HSV, VZV, or CMV in the aqueous humor, or classical signs of herpes zoster ophthalmicus. RESULTS: This study enrolled 259 herpetic AU patients, including PCR-proven HSV-AU (30 patients), VZV-AU (50), and CMV-AU (147), and herpes zoster ophthalmicus (32). All HSV-AU and VZV-AU patients were unilateral, while 3% of CMV-AU patients were bilateral. Most HSV-AU and VZV-AU patients were sudden onset with an acute clinical course, while CMV-AU had a more insidious onset and chronic course. There were no significant differences for all surveyed symptoms, signs, and complications between HSV-AU and VZV-AU. However, significant differences were detected for many items between CMV-AU and the other two herpetic AU types. Ocular hyperemia and pain, blurring of vision, ciliary injection, medium-to-large keratic precipitates (KPs), cells and flare in the anterior chamber, and posterior synechia significantly more often occurred in HSV-AU and VZV-AU vs CMV-AU. In contrast, small KPs, coin-shaped KPs, diffuse iris atrophy, elevated intraocular pressure, and glaucoma surgery were significantly more frequent in CMV-AU vs HSV-AU and VZV-AU. CONCLUSION: This multicenter, retrospective study identified distinguishing features of HSV-AU, VZV-AU, and CMV-AU.

Serum KL-6 elevation in a uveitis patient with Behçet's disease treated with adalimumab.

PURPOSE: To report a case of uveitis with Behçet's disease in which serum levels of Krebs von den Lungen (KL)-6, a marker of interstitial lung disease, were elevated during treatment with adalimumab and returned to baseline after discontinuation of the agent. OBSERVATIONS: A 67-year-old man complaining of vision disturbance was referred to our hospital. The patient had a history of recurrent episodes of bilateral uveitis and oral ulcers, and had been diagnosed with Behçet's disease. While uveitis activity was not well controlled under administration of oral prednisolone and cyclosporin, cataract of the right eye developed and required surgery. Biweekly administration of adalimumab 40 mg was therefore initiated with prednisolone at 15 mg/day. Uveitis became well controlled and cataract surgery was successfully carried out for the right eye. However, serum KL-6 gradually elevated to 1002 U/ml by 6 months after adalimumab initiation and 1277 U/ml at 9 months. Because serum KL-6 >1000 U/ml has been reported to predict interstitial lung disease, we discontinued adalimumab and started cyclosporine at 100 mg/day. Serum KL-6 gradually decreased and returned to baseline levels, no interstitial lung disease developed and exacerbation of uveitis was avoided. CONCLUSIONS AND IMPORTANCE: This case implies the clinical importance of monitoring serum KL-6 in patents with non-infectious uveitis being treated with adalimumab.

Spontaneous resolution of myopic foveoschisis and a macular hole with retinal detachment.

PURPOSE: The aim of this report was to describe a case of myopic foveoschisis and a macular hole with retinal detachment that resolved spontaneously. OBSERVATIONS: A 62-year-old woman with bilateral blurred vision was referred to our department. Her best-corrected visual acuity (BCVA) was 0.4 bilaterally; the standard equivalent refractive error was -17.0 diopters in the right eye and -18.75 diopters in the left eye. The axial length was 31.4 mm and 31.2 mm, respectively. After cataract surgery was performed, the BCVA of the right and left eye was 0.6 and 1.0, respectively. Four years later, slight macular traction, foveoschisis, and the macular hole had progressed in the left eye and the BCVA had decreased to 0.7. However, the macular hole had closed, the foveoschisis had resolved, and retinal detachment had mostly resolved three weeks later. The BCVA improved to 0.8. The macular hole did not reoccur and retinal detachment resolved completely after six more months. CONCLUSIONS AND IMPORTANCE: This case demonstrated that myopic foveoschisis and a macular hole with retinal detachment could improve spontaneously. It is necessary to decide carefully whether surgery is required or whether the patient should be observed.

Human T Cell Leukemia Virus Type 1 and Eye Diseases.

Human T cell leukemia virus type 1, also known as human T lymphotropic virus type 1 (HTLV-1), is a retrovirus that encodes a reverse transcriptase, which translates viral RNA into a DNA provirus that is integrated into the host genome. The virus was found to be a causative agent of adult T cell leukemia/lymphoma (ATL) in the early 1980s, and was also found to cause the neurological disorder tropical spastic paraparesis (TSP)/HTLV-1-associated myelopathy (HAM) and the inflammatory disorder HTLV-1 uveitis in the mid 1980s and early 1990s, respectively. This article reviews eye diseases caused by or related to HTLV-1: HTLV-1 uveitis, ocular and systemic complications of HTLV-1, keratoconjunctivitis sicca, interstitial keratitis, and ATL.

Treatment of rheumatoid arthritis with biologics may exacerbate HTLV-1-associated conditions: A case report.

RATIONALE: There are roughly 5 to 10 million persons infected with human T-lymphotropic virus type 1 (HTLV-1) worldwide, and the safety of treating this population with biologics remains poorly understood. PATIENT CONCERNS AND DIAGNOSIS: An HTLV-1-infected 66-year-old female with HTLV-1 uveitis (HU) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Her HU had been in remission and her HAM/TSP symptoms had been managed effectively with oral steroids for years. However, she developed severe rheumatoid arthritis (RA) after failing to respond well to conventional anti-rheumatic agents. INTERVENTIONS: She was administered two intravenous 8mg/kg doses of the biologic tocilizumab. OUTCOMES: Subsequently, her RA symptoms resolved, but she suffered a recurrence of HU and exacerbation of HAM/TSP symptoms. When she was switched back to steroid-based treatment, HU and HAM symptoms both improved, but RA symptoms again worsened. Finally, an attempt to substitute the biologic abatacept and reduce the steroids failed when HAM/TSP symptoms again became aggravated. LESSONS: To the best of our knowledge, this represents the first report worldwide of a biologic aggravating HTLV-1-associated conditions. This report suggests that caution is advised when using biologics to treat HTLV-1-infected patients, though further research is required to clarify the situation.

Clinical utility of femtosecond laser-assisted astigmatic keratotomy after cataract surgery.

PURPOSE: To examine the clinical utility of femtosecond laser-assisted astigmatic keratotomy (FSL-AK) for eyes after cataract surgery. METHODS: Eight eyes of 6 patients with an intraocular lens and corneal astigmatism of 2.0 diopters (D) or more underwent FSL-AK. The mean preoperative manifest cylindrical refraction was 2.88 ± 0.64 D and the mean corneal astigmatism was 2.84 ± 0.83 D. Paired symmetrical arcuate incisions were created with the same settings, except for the incision depth. Uncorrected distance visual acuity (UDVA), manifest cylindrical power, and surgically induced astigmatism (SIA) were measured at 1 day, 1 week, and 1 month postoperatively. Fourier analysis of corneal topography and incision depths measured with anterior-segment optical coherence tomography were evaluated 1 month postoperatively. RESULTS: In all eyes, the UDVA improved at 1 week and 1 month postoperatively, and the manifest cylinder also decreased postoperatively, while the SIA showed overcorrections in 6 eyes. Fourier analysis showed decreases in spherical and regular astigmatic components and increases in higher-order irregularity. The mean incision depth was measured as 60 µm deeper than the intended depth. CONCLUSION: The FSL-AK effectively reduced corneal astigmatism and improved the UDVA, although it was demonstrated that the deeper incisions led to overcorrection.

Age differences in sarcoidosis patients with posterior ocular lesions.

PURPOSE: To determine if age- and gender-related differences are correlated with the clinical aspects of posterior ocular lesions in sarcoidosis patients. METHODS: Age at disease onset, gender, and ocular findings were obtained from clinical records. Out of the 84 patients enrolled in the study, 22 were 45 years old or younger while 62 were older than 45. After division of the fundus field into three areas, lesion locations were investigated. RESULTS: The mean age of disease onset in the male (44.5 ± 16.8 years) was lower than in the female (55.5 ± 16.8 years). The lesions at the posterior segment in the older patients were found to be located around the peripheral area. However, no statistically significant difference in the location of the lesions was found for gender. CONCLUSIONS: There was a statistically significant difference between younger and older sarcoidosis patients for the disease lesions. Lesions were located around the peripheral area at the posterior segment in older patients.

Comparison of the ocular characteristics of anterior uveitis caused by herpes simplex virus, varicella-zoster virus, and cytomegalovirus.

PURPOSE: To compare the clinical characteristics of anterior uveitis (AU) caused by herpes simplex virus (HSV), varicella-zoster virus (VZV), or cytomegalovirus (CMV). METHODS: The medical records were reviewed of 46 patients whose diagnoses were based on their clinical characteristics [e.g., unilateral involvement, presence of keratic precipitates (KPs), and elevation of intraocular pressure (IOP)] and on PCR detection of herpes virus DNA in the aqueous humor. The demographics, chief complaints, and clinical characteristics of the three types of herpetic AU were compared. RESULTS: Of the 46 patients with AU, eight had HSV-AU, 20 had VZV-AU, and 18 had CMV-AU. HSV-AU and VZV-AU shared common features, i.e., a relatively acute disease process and the presence of large KPs. Among the three groups of patients, the characteristic features of those with VZV-AU were severe intraocular inflammation, as shown by severe aqueous flare, highest viral load in the aqueous humor, and presence of segmental iris atrophy. In comparison, patients with CMV-AU had the mildest intraocular inflammation, lowest corneal endothelial cell density, and highest IOP. CONCLUSIONS: Although the AU caused by each of the three types of herpes viruses has a number of common features, each disease also has distinct features that should facilitate an accurate diagnosis.
