How can scrub typhus affect the health of a diabetic patient?

Question

Hello doctor,

I am really worried about my 52-year-old uncle, who was recently diagnosed with scrub typhus. He has had uncontrolled diabetes for years, and his blood sugar levels are typically around 260 to 300 mg/dL. He is experiencing a fever that would not go down, chills, and has developed a rash on his chest. The doctor prescribed antibiotics (I believe Doxycycline, though I am not sure of the exact name), but his blood sugar levels are fluctuating significantly. We have also noticed that he is feeling dizzy, and his appetite is gone.

Is the persistent fever a typical symptom of scrub typhus, or could his diabetes be making it worse? Additionally, can this infection cause damage to his kidneys or heart? What should we be monitoring at home, and how can we best manage his blood sugar levels while he is sick?

Any guidance would be greatly appreciated.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Scrub typhus is caused by the Orientia tsutsugamushi bacteria, which is transmitted through the bite of a larval trombiculid mite, typically found in areas with dense vegetation, such as forests or rich tree areas. The site where the mite bites and transmits the bacteria is typically characterized by a wound scab known as an "eschar."

Common symptoms of scrub typhus include high-grade fever with chills, loss of appetite, and a rash. If treatment is delayed beyond one week, the infection can progress and potentially involve multiple organs. However, if treatment is started within seven to 10 days, the condition is usually treatable and reversible.

Treatment typically involves Doxycycline (100 mg) to neutralize the bacteria, Paracetamol (500 mg) for fever, and Levocetirizine to help with chills and rashes. If Doxycycline is not well tolerated, Azithromycin can be used as an alternative. If the patient has diabetes (chronic high blood sugar) or hypertension (high blood pressure), their regular diabetic medications should be continued during treatment.

In your uncle’s case, his fever, chills, and loss of appetite are likely due to scrub typhus. If he is not eating properly and continues with his diabetic medications, he may feel weak, dizzy, and fatigued. Therefore, he needs to have proper nutrition during this time. If he is unable to eat, consider giving him oral rehydration solutions or intravenous (IV) fluids. In a hospital setting, blood sugar levels can be better controlled with Insulin, in addition to the antibiotics for scrub typhus.

If his condition worsens rapidly, an injection of Azithromycin may be necessary. If left untreated, scrub typhus can lead to multi-organ involvement, affecting the kidneys, liver, and brain.

In terms of monitoring at home, please track the following:

Oxygen saturation levels.
Fever progression and chills.
The rash and the appearance of the eschar (wound site).
Any changes in mental status, such as confusion or seizures (sudden uncontrolled brain activity).
Diarrhea or vomiting.

Routine tests, including complete blood count (CBC), liver function tests (LFTs), kidney function tests (KFTs), chest X-ray, and blood sugar levels, should be considered. If these symptoms or test results worsen, hospitalization will be necessary. If his condition improves and stabilizes, he may be able to recover at home.

Additionally, it would be beneficial to consult a diabetic specialist to better manage his blood sugar levels while he is undergoing treatment for scrub typhus.

I hope this helps.
