This is a
report of 2 cases of
human hydatidosis caused by
Echinococcus ortleppi in
Vietnam. The
patients were a 12-year-old
male (case 1) having a
cyst of 10.0×9.0 cm size in the
lung and a 50-year-old
female with a 3.0×3.3 cm-sized
cyst in the
heart.
Eosinophilia was 33.7% in the
male and 45.8% in the
female patient.
C-reactive protein was increased to 16.5 mg/L in the
male and 18.2 mg/L in the
female. Both
patients were positive for
ELISA at OD=2.5 and 3.1, respectively.
Echinococcus protoscolices were collected from the
cysts by
amniocentesis and
surgery. The protoscolices were identified as E. ortleppi by morphology and
analysis of mitochondrial
NADH dehydrogenase 1 (nad1)
gene sequence. Both
patients were cured by surgical resection of the
hydatid cyst combined with
albendazole medication. The E. ortleppi
infection in
lung is the second
report, and the other in the
heart is the first in
Vietnam.
