ABSTRACT

Introduction: Photodynamic therapy (PDT) has shown substantial benefit in the treatment of choroidal hemangioma (CH) in recent years. This report describes the use of PDT with overlapping spots in a patient with Sturge-Weber syndrome (SWS) and large circumscribed CH. Case Presentation: A 9-year-old girl with SWS and a history of glaucoma in her left eye was referred to a retina clinic for possible macular changes. Examination revealed decreased vision in the left eye, pigmentary changes in the macula, and choroidal thickening in the posterior pole. After being lost to follow-up for 2 years, the patient returned with further vision deterioration with best-corrected visual acuity (BCVA) of 20/150 and new subretinal fluid (SRF). Imaging findings were consistent with a diagnosis of CH and SRF. PDT with verteporfin was initiated on the entire area with multiple overlapping spots, resulting in resolution of SRF and improvement in visual acuity and choroidal contour. At 18-month post-treatment, the patient's BCVA was 20/25 with no recurrence of SRF or increased choroidal thickening. Significant pigmentary changes and subretinal hyper-reflective material were observed in the OCT of the treated area. Conclusion: Multiple overlapping laser spots of PDT can result in longstanding regression of large circumscribed CH in a patient with SWS with excellent final visual acuity. However, significant subretinal changes may also result following this method of treatment.

ABSTRACT

BACKGROUND: Serum globulin is a major component of total protein and can be elevated in inflammatory disease states. While inflammation is common in hemodialysis patients and associated with mortality and morbidity, the association between serum globulin and mortality has never been examined in hemodialysis patients. METHODS: In a retrospective cohort of 104 164 incident hemodialysis patients treated by a large dialysis organization from 2007 to 2011, we explored the association between baseline serum globulin, albumin: globulin (A:G) ratio and serum protein levels and all-cause, cardiovascular and infection-related mortality with adjustments for demographic variables and laboratory markers of malnutrition and inflammation using Cox proportional hazards models. RESULTS: Patients with a globulin concentration >3.8 g/dL had a higher all-cause and infection-related mortality risk {hazard ratio [HR] 1.11 [95% confidence interval (CI) 1.06-1.16] and HR 1.28 [95% CI 1.09-1.51], respectively} in the fully adjusted model when compared with the reference group of 3.0- <3.2 g/dL. In addition, patients with an A:G ratio <0.75 had a 45% higher all-cause mortality hazard [HR 1.45 (95% CI 1.38-1.52)] and patients with total serum protein <5.5 g/dL had a 34% higher risk of death [1.34 (95% CI 1.27-1.42)] when compared with the reference (A:G ratio 1.05- <1.15 and total serum protein 6.5- <7 g/dL). CONCLUSIONS: Among incident hemodialysis patients, a higher globulin level was associated with a higher mortality risk independent of other markers of malnutrition and inflammation, including albumin. A lower A:G ratio and serum protein was also associated with a higher mortality hazard. The mechanisms that contribute to elevated serum globulin should be further explored.

ABSTRACT

BACKGROUND: Patients with ESRD on maintenance hemodialysis (MHD) are particularly susceptible to dysregulation of energy metabolism, which may manifest as protein energy wasting and cachexia. In recent years, the endocannabinoid system has been shown to play an important role in energy metabolism with potential relevance in ESRD. N-acylethanolamines are a class of fatty acid amides which include the major endocannabinoid ligand, anandamide, and the endogenous peroxisome proliferator-activated receptor-α agonists, oleoylethanolamide (OEA) and palmitoylethanolamide (PEA). METHODS: Serum concentrations of OEA and PEA were measured in MHD patients and their correlations with various clinical/laboratory indices were examined. Secondarily, we evaluated the association of circulating PEA and OEA levels with 12-month all-cause mortality. RESULTS: Both serum OEA and PEA levels positively correlated with high-density lipoprotein-cholesterol levels and negatively correlated with body fat and body anthropometric measures. Serum OEA levels correlated positively with serum interleukin-6 (IL-6) (rho = 0.19; p = 0.004). Serum PEA and IL-6 showed a similar but nonsignificant trend (rho = 0.12; p = 0.07). Restricted cubic spline analyses showed that increasing serum OEA and PEA both trended toward higher mortality risk, and these associations were statistically significant for PEA (PEA ≥4.7 pmol/mL; reference: PEA <4.7 pmol/mL) after adjustments in a Cox model (hazard ratio 2.99; 95% confidence interval 1.04, 8.64). CONCLUSIONS: In MHD patients, OEA and PEA are significantly correlated with variables related to lipid metabolism and body mass. Additionally, higher serum levels of PEA are associated with mortality risk. Future studies are needed to examine the potential mechanisms responsible for these findings and their clinical implications.
