A case report: primary amoebic meningoencephalitis in a young Zambian adult
BACKGROUND: Primary amoebic meningoencephalitis (PAM) is a fulminant disease of the brain caused by Naegleria fowleri. Although the disease is rare, the case fatality rate is very high. In this report, we describe the first case of PAM in Zambia. CASE PRESENTATION: The patient presented with sudden...

Sumario: | BACKGROUND: Primary amoebic meningoencephalitis (PAM) is a fulminant disease of the brain caused by Naegleria fowleri. Although the disease is rare, the case fatality rate is very high. In this report, we describe the first case of PAM in Zambia. CASE PRESENTATION: The patient presented with sudden onset of seizures and fever on admission. On physical examination he was febrile, comatose and with a stiff neck. Cerebral spinal fluid (CSF) collected on admission did not reveal any organism on microscopy or culture but showed elevated white cell count. A working diagnosis of severe septicemia with acute meningoencephalitis was then made and the patient was started on IV Cephtriaxone (2 g) twice daily. Despite receiving treatment, his condition deteriorated. A second CSF sample collected on day 3 was also negative for bacteria and other organisms. However, a repeat CSF sample collected on day 8 revealed numerous motile organisms that were identified as Naegleria on microscopy and confirmed to be N. fowleri on polymerase chain reaction. The patient died on day 8 of hospital admission after having received one dose of Amphotericin B (50 mg). Features consistent with PAM were detected on autopsy. CONCLUSION: The isolation of N. fowleri in this patient calls for increased awareness among clinical and laboratory staff on suspected PAM cases to promptly diagnose and effectively manage the disease.
