Résumé

Scrub typhus is a mite-borne zoonotic disease caused by Orientia tsutsugamushi and commonly presents with fever, rash, and eschar. Systemic complications develop later in the illness including, meningoencephalitis, pericardial effusion, myocarditis, and pneumonitis. In this article, we will be presenting different neurological manifestations of scrub typhus along with functional outcomes studied at a tertiary care center in New Delhi. This ambispective observational study was conducted at Army Hospital Research and Referral, New Delhi, during January 2018- January 2020. Febrile illness, serologically confirmed as scrub typhus and developing neurological complications were included. A predesigned clinical proforma was recorded for demographics, clinical features, neurological examination, supported with laboratory and/or radiology evaluation, and functional outcomes using the modified Rankin Scale (mRS). In our cohort of 7 patients' majority were male (71%) with mean age at presentation being 42.5 years. Eschar was present in only 2 cases (28%) and a syndromic clinical diagnosis of meningoencephalitis was made in 3 (43%), acute flaccid quadriparesis in 2 (28%); and symptomatic seizure and parkinsonism in 1 patient each (14%). CSF showed lymphocytic pleocytosis with protein elevation in 57% cases. Systemic dysfunction was noted in the form of thrombocytopenia (57%), hyponatremia (42%), elevated transaminases (57%). Symptoms resolved with Doxycycline ± Rifampicin therapy in all cases, with good functional outcomes in majority of (89%) cases. Neurological complications in scrub typhus have a wide spectrum involving meninges, encephalon, basal ganglia, cranial, and peripheral nerves. High index of suspicion with early serological testing (ELISA) is a must in undifferentiated fevers. Timely initiation of appropriate therapy leads to good clinical outcomes, in majority of cases with neurological involvement.

BACKGROUND BACKGROUND
Scrub typhus is a mite-borne zoonotic disease caused by Orientia tsutsugamushi and commonly presents with fever, rash, and eschar. Systemic complications develop later in the illness including, meningoencephalitis, pericardial effusion, myocarditis, and pneumonitis. In this article, we will be presenting different neurological manifestations of scrub typhus along with functional outcomes studied at a tertiary care center in New Delhi.
METHODS METHODS
This ambispective observational study was conducted at Army Hospital Research and Referral, New Delhi, during January 2018- January 2020. Febrile illness, serologically confirmed as scrub typhus and developing neurological complications were included. A predesigned clinical proforma was recorded for demographics, clinical features, neurological examination, supported with laboratory and/or radiology evaluation, and functional outcomes using the modified Rankin Scale (mRS).
RESULTS RESULTS
In our cohort of 7 patients' majority were male (71%) with mean age at presentation being 42.5 years. Eschar was present in only 2 cases (28%) and a syndromic clinical diagnosis of meningoencephalitis was made in 3 (43%), acute flaccid quadriparesis in 2 (28%); and symptomatic seizure and parkinsonism in 1 patient each (14%). CSF showed lymphocytic pleocytosis with protein elevation in 57% cases. Systemic dysfunction was noted in the form of thrombocytopenia (57%), hyponatremia (42%), elevated transaminases (57%). Symptoms resolved with Doxycycline ± Rifampicin therapy in all cases, with good functional outcomes in majority of (89%) cases.
CONCLUSION CONCLUSIONS
Neurological complications in scrub typhus have a wide spectrum involving meninges, encephalon, basal ganglia, cranial, and peripheral nerves. High index of suspicion with early serological testing (ELISA) is a must in undifferentiated fevers. Timely initiation of appropriate therapy leads to good clinical outcomes, in majority of cases with neurological involvement.
