A human immunodeficiency virus-positive woman with toxic epidermal necrolysis treated with human intravenous immunoglobulin

We report an Acanthamoeba keratitis case associated with the use of contact lens in a 28-year-old female from Bras ília, Brazil. Samples from corneal scraping and contact lens case were used for culture establishment, PCR amplification, and partial sequencing (fragments of ~400kb) of small subunit rDNA; both culture and PCR were positive. The sequence analyses of the cornea and of isolates from the contact lens case showed similarity with the T4 genotype. To the best of our knowledge, this is the first report of T4 Acanthamoeba keratitis case from the Midwest region of Brazil.

Authors: Tananuvat N, Techajongjintana N, Somboon P, Wannasan A Abstract Acanthamoeba keratitis (AK) is a rare sight-threatening corneal infection, often reporting from contact lens wearers. An asymptomatic human immunodeficiency virus (HIV)-infected Thai male without history of contact lens use complained foreign body sensation at his left eye during motorbike riding. He had neither specific keratitis symptoms nor common drugs responding, which contributed to delayed diagnosis. By corneal re-scraping, Acanthamoeba-like cysts were detected by calcofluor white staining and agar culture. The etiological agent obtaine...

Abstract PURPOSE: To study the surgical outcome of therapeutic penetrating keratoplasty (TPK) for medically uncontrolled microbial keratitis at a tertiary hospital in Taiwan over a 14-year period. METHODS: This is a retrospective case series study. Patients who underwent TPK at National Taiwan University Hospital in 2001-2014 were included. Patients were divided into 3 diagnostic groups: bacterial keratitis, fungal keratitis, and acanthamoeba keratitis. Each of the following criteria was evaluated: graft clarity at 1 month and 1 year postoperatively, cure of the disease, and anatomical success rate. RESU...

This patient with recurrent unilateral ocular complaints, a lid lesion, and keratitis unresponsive to numerous medications as well as a negative work-up for infectious agents leaves us with numerous diagnostic possibilities. These include: viral shedding from the lid lesion as with molluscum, eyelid deformity with corneal exposure, limbal stem cell deficiency of uncertain etiology, ocular surface dysplasia or neoplasia, superior limbic keratoconjunctivitis, vernal keratoconjunctivitis, herpes group viruses, Acanthamoeba keratitis, eyelid foreign body, medicamentosa, and many others.

Conclusions: In an in vitro assay, voriconazole reduced the cysticidal activity of 2 commonly used antiamoebic drugs. Although the in vivo drug interactions could be different, these observations may be useful in cases of nonhealing Acanthamoeba keratitis being treated with combination therapies that include voriconazole.

CONCLUSION: PHMB 0.02% monotherapy for the initial treatment of AK is as effective as biguanide+diamidine combination therapy. Chlorhexidine monotherapy was too infrequent for comparison. The outcome data are the most detailed available. PMID: 31401556 [PubMed - as supplied by publisher]

ConclusionPKP à chaud within 5.3 months after first symptoms of therapy-resistant AK seems to result in better final BCVA than delayed graft surgery if the disease is resistant to a classical topical triple therapy. In addition, early PKP may have a favorable impact on epithelial healing and graft survival.FundingWe thank the Alexander von Humboldt Foundation for supporting the work of Prof. N.
