Glaucomatous damage in normotensive fellow eyes of patients with unilateral hypertensive pseudoexfoliation glaucoma: normotensive pseudoexfoliation glaucoma?

BACKGROUND: The objective of the study was to investigate the prevalence of glaucomatous damage in normotensive fellow eyes of patients with unilateral high-tension pseudoexfoliation (PX) glaucoma. METHODS: Initial examination records of 111 patients with unilateral PX glaucoma with intraocular pressure (IOP) > or = 22 mmHg in the hypertensive eye and IOP < or = 21 mmHg in the normotensive fellow eye without any prior antiglaucomatous treatment were retrospectively studied. Visual field and optic disc examination results were evaluated for glaucomatous damage in the normotensive eyes. RESULTS: Glaucomatous changes were detected in 45 of the 111 fellow eyes (40%). The damage was mild in 25 eyes (22%), moderate in 18 eyes (16%), and severe in 2 (2%). The factors significantly associated with glaucomatous findings in the normotensive eyes were clinical detection of PX, higher age (> or =70 years), higher maximal IOP (> or =18 mmHg) and wider IOP fluctuation (> or =6 mmHg) in the univariate analyses. In the multivariate analysis, associated factors remained as higher maximal IOP (odds ratio = 7.92, confidence interval = 2.82-22.23, P < 0.001) and wider IOP fluctuation (odds ratio = 5.67, confidence interval = 2.05-15.74, P = 0.001). CONCLUSION: Normotensive fellow eyes of patients with unilateral high-tension PX glaucoma are under significant risk of glaucomatous damage, related with the level and the fluctuation range of IOP.

Adiponectin levels and atherosclerotic risk factors in pediatric chronic peritoneal dialysis patients.

BACKGROUND: Atherosclerotic vascular diseases are the major cause of mortality in patients with end-stage renal disease (ESRD) treated with chronic peritoneal dialysis (CPD), even in children. Adiponectin (ADPN) is a recently discovered adipocyte-derived plasma protein having anti-atherogenic properties. ADPN levels are elevated in ESRD but it has been reported that ESRD patients with low plasma ADPN levels have a high risk of cardiovascular death. OBJECTIVE: To clarify the atherosclerotic risk and especially the significance of ADPN levels in pediatric patients on CPD. DESIGN: Cross-sectional studyin the pediatric peritoneal dialysis unit of a university hospital. PATIENTS: 18 children, aged 12.6 +/- 5.6 years, being treated with CPD and 20 healthy age- and sex-matched control subjects were enrolled in this study. METHODS: Serum ADPN levels and other risk factors, including blood pressure, blood glucose, serum lipid/lipoprotein fractions, apolipoprotein B, C-reactive protein (CRP), lipoprotein(a), and homocysteine levels, were studied in CPD patients and compared to the controls. RESULTS: Serum ADPN levels were three times higher in the CPD group compared to the control subjects, as was previously reported. Apolipoprotein B and CRP levels were also high in the CPD group. No significant difference was found in other atherosclerotic parameters, including lipoprotein(a) and homocysteine levels. Interestingly, we found a negative correlation between log ADPN and creatinine levels among the CPD patients (r = -0.54, p < 0.05). There was no correlation between log ADPN and duration of CPD. Creatinine and low-density lipoprotein levels could account for 54% of the total variation in ADPN levels. CONCLUSION: Among pediatric CPD patients, serum levels of the anti-atherogenic protein, ADPN, were inversely associated with creatinine. ADPN level might be a novel marker to predict prognosis in pediatric CPD patients.
