The relationship between high levels of anti-Varicella Zoster Virus (VZV) IgG in cerebrospinal fluid (CSF) and cerebrovascular atherosclerosis commends a possible similar association in other vessels. We aimed to investigate the association of VZV-seropositivity with coronary artery atherosclerosis. We recruited 88 newly diagnosed patients with more than 50% stenosis in at least one of the main coronary arteries. As the control group, 99 age-matched individuals with normal/insignificant coronary artery findings were included. Clinical, paraclinical, and demographical data were gathered at the time of sampling. High-sensitivity C-reactive protein(hsCRP) levels were measured by nephelometry. VZV-seropositivity was determined by measuring of anti-VZV IgG level in . plasma. Multivariable logistic regression was used to evaluate the correlation of data with coronary vascular atherosclerosis. The frequency of VZV-seropositivity was significantly higher in the atherosclerosis group compared to the controls (OR=1.88; 95%CI=1.03-3.44). The plasma levels of anti-VZV IgG were significantly higher in patients with atherosclerosis (Median=2.70, IQR=1.53-4.30 AU/mL) than in the controls (Median=2.10, IQR=1.70-3.10 AU/mL,p=0.034). The hsCRP levels in patients and controls were 5.19 +/- 2.00 and 1.51 +/- 1.07 mg/L, respectively. The correlation between hsCRP and anti-VZV IgG level in plasma was observed (r=0.40, p<0.001). The levels of hsCRP and anti-VZV IgG increased based on the number of diseased vessels but only the difference in hsCRP levels reached a significant level (p<0.001 and p=0.168, respectively). Our data suggest that VZV-seropositivity and hsCRP elevation jointly increase the risk of atherosclerosis. The multifactorial nature of atherosclerosis; however, leaves more options for the inflammatory milieu to be generated.

A 54 year old female presented to the ophthalmology clinic with pain and decreased vision in her left eye. No past medical history other than primary varicella zoster infection, in her childhood. The eye exam revealed a macular region with scattered areas of retinal opacity along with patches of necrosis on the periphery. She was started on valganciclovir and referred to the infectious disease clinic. Cell Count, blood chemistry and HIV were negative. Serum was sent for polymerase chain reaction (PCR) for Varicella Zoster Virus (VZV), Herpes Simplex Virus (HSV) and Cytomegalovirus (CMV). The VZV PCR was positive. She had decreased vision on the right eye two days later, and exam revealed peripheral retinal whitening. She was admitted and started on intravenous acyclovir. VZV is one of the most common causes of ARN and has been described in both immunocompetent and immunocompromised persons. Visual changes are usually noted weeks to months after the antecedent herpes zoster. Retinal involvement is bilateral in over half of cases, suggesting that VZV reaches the central nervous system hematogenously. The retinal exam reveals multifocal necrotizing lesions, often initially involving the peripheral retina. Therapy includes intravenous acyclovir with consideration of intravitreal foscarnet and other antivirals for progressing disease. (C) 2019 Published by Elsevier Ltd.
