Background/Aim: To describe a case of invasive orbital aspergillosis and evaluate treatments and outcomes. Methods: A case report and review of orbital aspergillosis treatment with voriconazole in the English language literature. Conclusion: Amphotericin B with debridement is the current standard of care for orbital aspergillosis; however, its prognosis is unfavorable. When compared to amphotericin B, voriconazole demonstrates a survival benefit, has less systemic toxicity, and is better tolerated by patients. While a prospective trial comparing amphotericin B to voriconazole in orbital aspergillosis is not feasible, there is evidence to support the use of voriconazole as primary therapy.

Giant cell arteritis (GCA) and Takayasu’s disease are inflammatory vasculitic syndromes (IVS) causing sudden blindness and widespread arterial obstruction and aneurysm formation. Glucocorticoids and aspirin are mainstays of treatment, predominantly targeting T cells. Serp-1, a Myxomavirus-derived serpin, blocks macrophage and T cells in a wide range of animal models. Serp-1 also reduced markers of myocardial injury in a Phase IIa clinical trial for unstable coronary disease. In recent work, we detected improved survival and decreased arterial inflammation in a mouse Herpesvirus model of IVS. Here we examine Serp-1 treatment of human temporal artery (TA) biopsies from patients with suspected TA GCA arteritis after implant (TAI) into the aorta of immunodeficient SCID (severe combined immunodeficiency) mice. TAI positive for arteritis (GCApos) had significantly increased inflammation and plaque when compared to negative TAI (GCAneg). Serp-1 significantly reduced intimal inflammation and CD11b+ cell infiltrates in TAI, with reduced splenocyte Th1, Th17, and Treg. Splenocytes from mice with GCApos grafts had increased gene expression for interleukin-1beta (IL-1β), IL-17, and CD25 and decreased Factor II. Serp-1 decreased IL-1β expression. In conclusion, GCApos TAI xenografts in mice provide a viable disease model and have increased intimal inflammation as expected and Serp-1 significantly reduces vascular inflammatory lesions with reduced IL-1β.

Large and giant paraclinoid aneurysms are challenging to treat by either surgical or endovascular means. Visual dysfunction secondary to optic nerve compression and its relationship with aneurysm size, pulsation and thrombosis is poorly understood. We present a patient with a giant paraclinoid aneurysm resulting in bilateral visual loss that worsened following placement of a Pipeline Embolization Device and adjunctive coiling. Visual worsening occurred in conjunction with aneurysm thrombosis, increase in maximal aneurysm diameter and new adjacent edema. Her visual function spontaneously improved in a delayed fashion to better than pre-procedure, in conjunction with reduced aneurysmal mass effect, size and pulsation artifact on MRI. This report documents detailed ophthalmologic and MRI evidence for the role of thrombosis, aneurysm mass effect and aneurysm pulsation as causative etiologies for both cranial nerve dysfunction and delayed resolution following flow diversion treatment of large cerebral aneurysms.

A case of fulminant bilateral chorioretinitis and papillitis that resulted in bilateral vision loss despite high-dose steroids within 24 hours of initial loss in vision is presented in this study. The patient was found to have high titers of coxsackievirus B3, B4,B5 after presentation and her condition improved after treatment with intravenous immunoglobulin, suggesting a plausible immune component.
