Bartonella Henselae-Associated Recurrent, Bilateral Segmental Periphlebitis
American journal of ophthalmology case reports(2022)
摘要
Purpose: To describe a patient with atypical Bartonella henselae (B. henselae)-associated ocular inflammation that manifested with recurrent, bilateral segmental periphlebitis. Observations: A 32-year-old White man presented with multiple paracentral scotomata in each eye. Examination revealed mild vitreous cell, segmental sheathing of the retinal veins, and inflammation of the paravenous retina in each eye. Multimodal imaging, including optical coherence tomography as well as widefield fundus autofluorescence, fluorescein angiography, and indocyanine green angiography, was consistent with bilateral, segmental retinal periphlebitis with paravenous inflammation and retinochoroidal scarring. Serology showed elevated B. henselae antibody titers, but was otherwise unrevealing, and the patient was diagnosed with presumed B. henselae-associated ocular inflammation. Treatment with systemic doxycycline (100 mg PO BID) for four weeks improved the patient's symptoms and posterior uveitis. However, after an asymptomatic period of nearly one year, his bilateral pericentral scotomata recurred and posterior segment examination confirmed new foci of retinal periphlebitis in each eye. Re-treatment with doxycycline (100 mg PO BID) for four weeks again yielded improvement, but one month after completing his antibiotic course, his visual symptoms recurred, and we observed additional areas of periphlebitis and paravenous retinitis with associated branch retinal vein occlusions in each eye. This time a dual antibiotic regimen of doxycycline (100 mg PO BID) and rifampin (300 mg PO BID) was administered for three months, with improvement. Over the next eight years, the patient experienced no further disease relapse, and the previous sites of retinal periphlebitis eventually developed perivenous fibrosis with paravenous retinochoroidal scarring. Conclusion: Rarely, patients with B. henselae-associated ocular inflammation develop segmental retinal periphlebitis with or without retinal vein occlusion. This form of ocular bartonellosis can recur, requiring multiple courses of antimicrobial therapy.
