What are the complications of scrub typhus?

Question

Hello doctor,

Last week, my uncle was diagnosed with scrub typhus and put on doxycycline. His fever has gone down, but he has become very confused and disoriented. The doctor said it could be due to general weakness, but I have read that scrub typhus can sometimes affect the brain.

Should we be concerned about neurological complications such as encephalitis? Recent blood tests showed elevated liver enzymes and a low platelet count. Are these results typical of scrub typhus, or do they indicate that his condition is getting worse? Should we do a brain MRI (magnetic resonance imaging) or a spinal tap to rule out serious complications? We want to make sure we are not missing anything before his condition worsens.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Neurological complications of scrub typhus are

Confusion and disorientation: While weakness can confuse, scrub typhus can affect the brain, leading to neurological complications like encephalitis.
Concerns: Given your uncle's symptoms, it's essential to investigate further to rule out serious neurological complications.

Blood test findings

Elevated liver enzymes: This is a common finding in scrub typhus, indicating liver inflammation.
Low platelet counts: Thrombocytopenia (low platelet count) is also common in scrub typhus, increasing the risk of bleeding.

Further testing

Brain MRI: A brain MRI may be necessary to rule out encephalitis or other neurological complications.
Spinal tap (lumbar puncture): This test may be performed to check for meningitis or encephalitis.

Next steps

Consult an infectious disease specialist: Consider consulting an infectious disease specialist for further guidance if clinically deteriorating.
Monitor vital signs: Closely monitor your uncle's vital signs, including temperature, blood pressure, and oxygen saturation.

I hope this information helps you.

Thank you.
