چکیده
INTRODUCTION This case report describes a human survivor of Balamuthia mandrillaris infection. This is a free-living amoeba that can cause infection with the devastating consequence of near universally fatal encephalitis. We report this case to demonstrate the possibility of recovery. CASE PRESENTATION A 26-year-old Hispanic male, a landscape gardener, presented to the hospital in March 2010 with a two month history of headache, visual disturbances and new-onset seizures. Brain imaging identified two enhancing central lesions and Balamuthia mandrillaris was later identified by brain biopsy. He received several months of various antimicrobials including miltefosine, a novel use of the drug in this disease at the time. Seven weeks into therapy, considerations were made to switch him to 'comfort care' because of worsening clinical status and seemingly lack of response to treatment. The patient finally demonstrated clinical and radiological improvement after eight weeks with modified therapy, despite experiencing some debilitating toxic effects likely to be related to antibiotics. Two years after his initial presentation he made a complete recovery. CONCLUSION Balamuthia mandrillaris amoebic encephalitis is considered an almost universally fatal disease; this case demonstrates the possibility of recovery. This report outlines his treatment, drug toxicities and includes additional information regarding the therapeutic use of the drug miltefosine. Whether his survival is related to the specific antimicrobials used in this case is unknown and further investigation is warranted.

Balamuthia mandrillaris: identification of clinical and environmental isolates using genus-specific PCR.
The protist genus Balamuthia was first described as the causative agent of a fatal case of encephalitis in a mandrill [8]. Originally classified as a leptomyxid ameba, it was eventually given genus status as Balamuthia mandrillaris [8,9]. Since the original isolation, numerous isolates have been found in granulomatous amebic encephalitis (GAE) cases in a number of vertebrates, including humans,...
متن کاملIdentification of Balamuthia mandrillaris by PCR assay using the mitochondrial 16S rRNA gene as a target.
Balamuthia mandrillaris is an opportunistic pathogen that causes granulomatous amebic meningoencephalitis in animals, including humans. Based on sequence analysis of mitochondrial small-subunit-rRNA genes, we developed primers that amplify a Balamuthia-specific PCR product. These primers will be useful for retrospective analyses of fixed tissues and possible identification of Balamuthia in vivo.

Balamuthia amoebic encephalitis is a rare infection but it almost always proves fatal with the mortality rate of more than 95%. Thus it is not surprising that the majority of cases are identified at the post-mortem stage. Early diagnosis followed by aggressive treatment may lead to successful prognosis for the patient. The clinical diagnosis requires a high level of suspicion, awareness of the ...
