Background Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is often fatal. Although pharmacological treatments have been studied, outcomes remain poor. This study evaluated the effectiveness of pharmacological treatments for AE-IPF. Methods This retrospective study comprised 88 patients who received a diagnosis of AE-IPF and were admitted to our center during the period from January 2008 through April 2017. We reviewed the clinical features, treatments, and outcomes of the 88 patients. Cox proportional hazards regression analysis was used to identify variables that were significant predictors of 3-month death. Results Data from 88 AE-IPF patients (age range, 56-81 years) were analyzed. In all patients, corticosteroid (CS) pulse therapy was performed an average of 1.7 times, and the initial CS maintenance dose was 1 mg/kg for 65 patients and 0.5 mg/kg for 23 patients. The combination treatments received were sivelestat in 83 patients (94%), recombinant human thrombomodulin (rhTM) in 45 patients (51%), pirfenidone in 41 patients (47%), and cyclosporine in 71 patients (81%). Univariate analysis showed that use of rhTM, and an initial CS maintenance dose of 0.5 mg/kg were associated with better 3-month survival. In multivariate analysis, both use of rhTM and an initial CS maintenance dose of 0.5 mg/kg were associated with better 3-month survival. Other treatments, including sivelestat, cyclosporine, pirfenidone, and polymyxin B-immobilized fiber column-direct hemoperfusion, were not associated with better 3-month survival. Conclusion Addition of rhTM to CS, and a low initial CS maintenance dose (0.5 mg/kg), were associated with better 3-month survival in patients with AE-IPF.Purpose Family-based genetic linkage analysis and genome-wide association studies (GWASs) have identified many genomic loci associated with primary open-angle glaucoma (POAG). Several causative genes of POAG have been intensively analyzed by sequencing in different populations. However, few investigations have been conducted on the identification of variants of coding region in the genes identified in GWASs. Therefore, further research is needed to investigate whether they harbor pathogenically relevant rare coding variants and account for the observed association. Methods To identify the potentially disease-relevant variants (PDVs) in POAG-associated genes in Chinese patients, we applied molecular inversion probe (MIP)-based panel sequencing to analyze 26 candidate genes in 235 patients with POAG and 241 control subjects. Results The analysis identified 82 PDVs in 66 individuals across 235 patients with POAG. By comparison, only 18 PDVs in 19 control subjects were found, indicating an enrichment of PDVs in the POAG cohort (28.1% versus 7.9%, p = 8.629e-09). Among 26 candidate genes, the prevalence rate of PDVs in five genes showed a statistically significant difference between patients and controls (33 out of 235 versus 1 out of 241, p = 4.533e-10), including ATXN2 (p = 0.0033), TXNRD2 (p = 0.0190), MYOC (p = 0.0140), FOXC1 (p = 0.0140), and CDKN2B (p = 0.0287). Acetyl-CoA carboxyla chemical Furthermore, two sisters harboring a stop-loss mutation EFEMP1 p.Ter494Glu were found in the POAG cohort, and further analysis of the family strongly suggested that EFEMP1 p.Ter494Glu was a potentially disease-causing mutation for POAG. A statistically significant difference in age at diagnosis between patients with PDVs and those without PDVs was found, implying that some of the identified PDVs may have a role in promoting the early onset of POAG disease. Conclusions The results suggest that some of the associations identified in POAG risk loci can be ascribed to rare coding variants with likely functional effects that modify POAG risk.Purpose Risk for age-related macular degeneration (AMD), a slowly progressing, complex disease, is tied to an overactive complement system. Efforts are under way to develop an anticomplement-based treatment to be delivered locally or systemically. We developed an alternative pathway (AP) inhibitor fusion protein consisting of a complement receptor-2 fragment linked to the inhibitory domain of factor H (CR2-fH), which reduces the size of mouse choroidal neovascularization (CNV) when delivered locally or systemically. Specifically, we confirmed that ARPE-19 cells genetically engineered to produce CR2-fH reduce CNV lesion size when encapsulated and placed intravitreally. We extend this observation by delivering the encapsulated cells systemically in Matrigel. Methods ARPE-19 cells were generated to stably express CR2 or CR2-fH, microencapsulated using sodium alginate, and injected subcutaneously in Matrigel into 2-month-old C57BL/6J mice. Four weeks after implantation, CNV was induced using argon laser photocoagulation. Progression of CNV was analyzed using optical coherence tomography. Bioavailability of CR2-fH was evaluated in Matrigel plugs with immunohistochemistry, as well as in ocular tissue with dot blots. Efficacy as an AP inhibitor was confirmed with protein chemistry. Results An efficacious number of implanted capsules to reduce CNV was identified. Expression of the fusion protein systemically did not elicit an immune response. Bioavailability studies showed that CR2-fH was present in the RPE/choroid fractions of the treated mice, and reduced CNV-associated ocular complement activation. Conclusions These findings indicate that systemic production of the AP inhibitor CR2-fH can reduce CNV in the mouse model.Purpose To explore the correlation of tear and conjunctival cytokines and sensory hypersensitivity in mild dry eye (MDE) patients characterized by symptoms outweighing signs (DESOS). Methods The subjects comprised 39 patients with MDE characterized by DESOS, 18 patients with common MDE (CMDE), and 15 healthy controls. The patients with DESOS were randomly subdivided into two groups; the C-DESOS group received artificial tears only, and the G-DESOS group received artificial tears and 0.1% fluorometholone eye drops three times a day. Symptoms were assessed using the Ocular Surface Disease Index (OSDI) and the Neuropathic Pain Symptoms Inventory modified for Eye (NPSI-E) questionnaire. Ocular examinations and in vivo confocal microscopy (IVCM) were also employed. Tear and conjunctival cytokines were measured using Multiplex or RT-PCR on Days 0, 7, and 30. The correlation between the expression of cytokines and hypersensitivity status was analyzed. Results Compared with the CMDE and control groups, the DESOS groups showed a significant increase in symptom scores and in the ratio of symptoms versus signs. IL-1 β, IL-2, IL-6, and TNF-α in tears and conjunctiva increased in the DESOS groups compared to the CMDE and control groups, indicating a high correlation with hypersensitivity status in the DESOS groups. Glucocorticoid treatment significantly decreased the level of cytokines in tears and conjunctiva in the G-DESOS group and subsequently ameliorated the symptoms. Conclusions Tear and conjunctival cytokines, including IL-1 β, IL-2, IL-6, and TNF-α, were correlated with sensory hypersensitivity status in the DESOS groups, suggesting they play an important role in the discordance of symptoms outweighing signs.Despite decades of research, diabetic retinopathy remains the leading cause of blindness in working age adults. Treatments for early phases for the disease remain elusive. One pathway that appears to regulate neuronal, vascular, and inflammatory components of diabetic retinopathy is the cyclic adenosine 3', 5'-monophosphate (cAMP) pathway. In this review, we discuss the current literature on cAMP actions on the retina, with a focus on neurovascular changes commonly associated with preproliferative diabetic retinopathy models.Purpose North Carolina macular dystrophy (NCMD) is an autosomal dominant maculopathy that is considered a non-progressive developmental disorder with variable expressivity. Our study aimed to clinically and genetically characterize macular dystrophy in a family (MOL1154) consisting of six affected subjects with a highly variable maculopathy phenotype in which no correlation between age and severity exists. Methods Clinical characterization included visual acuity testing and electroretinography. Genetic analysis included Sanger sequencing and whole exome sequencing (WES). Results WES analysis performed on DNA samples from two individuals revealed a heterozygous deletion of six nucleotides [c.2247_2252del; p.(Leu750_Lys751del)] in the CFH gene. Co-segregation analysis revealed that five of the six NCMD affected subjects carried this deletion, while one individual who had a relatively mild phenotype compatible with dry age-related macular degeneration (AMD) did not carry it. We subsequently analyzed the upstream region of PRDM13 that has previously been reported to be associated with NCMD and identified a unique heterozygous transversion (chr6100040974A>C) located within the previously described suspected control region in all six affected individuals. This transversion is likely to cause NCMD. Conclusions NCMD has a wide spectrum of clinical phenotypes that can overlap with AMD, making it challenging to correctly diagnose affected individuals and family members. The DNA sequence variant we found in the CFH gene of some of the affected family members may suggest some role as a modifier gene. However, this variant still does not explain the huge phenotypic variability of NCMD and needs to be studied in other and larger populations.Long-standing atrial fibrillation is associated with significant morbidity including stroke and development of heart failure. Patients also report poor quality of life as a result of debilitating symptoms or treatment side effects from antiarrhythmic medications. Radio frequency or cryothermal mediated catheter ablation has a central role in the management of symptomatic patients with paroxysmal or persistent atrial fibrillation. Circumferential pulmonary vein isolation is vital to the success of this therapy and other ancillary techniques have been described, especially for persistent atrial fibrillation. Several randomized controlled studies have been reported over the last two decades studying important clinical outcomes in patients with atrial fibrillation. In this article, we aim to provide a review of the major studies that have helped define the role of catheter ablation in the management of symptomatic atrial fibrillation in patients with both diseased and structurally normal hearts.Atrial fibrillation is a common arrhythmia which may cause symptoms that significantly impact quality of life and is associated with increased risk of stroke, heart failure, and sudden death. Over the past three decades many surgical techniques as well as catheter-bases procedures have been developed to treat atrial fibrillation. In this review we describe the indications, treatments, outcomes, surgical techniques, and technical advances reported in the literature.Atrial fibrillation is the most common arrhythmia in the adult population, and its incidence and prevalence are still rising. Cardiac devices are widely used in clinical practice in the management of various rhythm disturbances and heart failure treatment. Many patients who receive a pacemaker, implantable cardioverter-defibrillator, or cardiac resynchronization therapy also experience atrial fibrillation in the course of their life. Therefore, this review aims to describe the role of these devices in the treatment and prevention of atrial fibrillation in the device recipients. In addition, all these implantable devices also serve as permanent ECG (electrocardiogram) monitors, thus providing important information about the presence and characteristics of atrial fibrillation that may or may not be detected by the patient but can modify our therapeutical approach with regard to the stroke prevention.
