Rheumatic Fever – Diagnosis and Treatment

Rheumatic fever is a serious health condition that can develop after a throat infection caused by certain types of bacteria. It most often affects children and teenagers but can occur at any age.

This disease can lead to lasting problems, especially with the heart, if not treated properly. Early recognition and proper care play a key role in managing symptoms and preventing complications.

Diagnosis

Laboratory and Imaging Evaluations

Doctors use a mix of clinical tools to diagnose rheumatic fever because no single test can confirm it.

They usually begin by thoroughly reviewing symptoms such as joint pain, skin rashes like erythema marginatum, subcutaneous nodules, a heart murmur, and signs of heart inflammation.

Key assessments often include:

  • Blood Tests:
    • C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) track inflammation.
    • Other blood tests check for antibodies against streptococcal pharyngitis.
  • Throat Culture or Rapid Antigen Test: This detects an ongoing or recent strep infection.
  • Echocardiography and Doppler: These create images of the heart and help find problems related to rheumatic heart disease and track blood movement.
  • Electrocardiogram (EKG): An EKG can reveal a prolonged PR interval, which may be linked to rheumatic fever.

Doctors often use the Jones criteria recommended by groups like the American Heart Association to confirm the diagnosis.

Test/Sign Purpose
CRP, ESR Detect inflammation
Throat Culture Find strep infection
EKG Spot heart rhythm issues
Echocardiography View heart structure/function

Treatment

Medications Used for Treatment

Doctors primarily treat rheumatic fever with antibiotic therapy to eliminate the strep infection.

They often use penicillin-based antibiotics or suitable alternatives to clear the bacteria from the body. Some patients may receive other types of antibiotics if they have allergies.

After the initial course, patients typically continue on long-term, low-dose antibiotic prophylaxis to prevent rheumatic fever from returning.

The length of this treatment depends on individual risk factors and whether the heart was affected. In some cases, it continues for 5 to 10 years or longer, especially if heart inflammation occurred.

To reduce joint pain and swelling, doctors recommend nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin or naproxen, which help lower inflammation.

If NSAIDs are not effective or if symptoms are severe, corticosteroids may be prescribed. In some cases, salicylates are also used to ease inflammation.

If a patient develops involuntary movements, such as those seen in Sydenham chorea, doctors may prescribe anticonvulsant medications to help control the symptoms.

Medicine Type Main Purpose
Antibiotics Remove strep infection, prevent return
NSAIDs and Salicylates Reduce inflammation, ease symptoms
Corticosteroids Lessen severe swelling
Antiseizure Drugs Treat involuntary movement

Simple Daily Habits and Self-Care

  • Doctors often recommend bed rest until symptoms improve.
  • Patients may need to limit physical activities.
  • Following these steps supports recovery and helps prevent complications.

Getting Ready for Your Visit

Steps You Can Take Beforehand

Before the appointment, patients should ask if any special steps are required. For example, some blood tests may require fasting for a short time.

It helps to make a list of important information, such as:

  • Current symptoms, including anything unusual, even symptoms that do not seem to be related.
  • Key personal details, such as major stress, recent changes in life, and any family history of medical problems.
  • A record of medication, including all prescribed drugs, over-the-counter medicines, vitamins, or supplements, plus how much is taken of each.

Bringing this information eases communication with the healthcare team. Keeping a written list ensures nothing important is missed during the visit.

A list of questions can also help. Useful questions could include:

  • What could be causing these symptoms?
  • Which tests are needed?
  • What treatment do you recommend?
  • Are there other treatments available?
  • How should other health problems be handled with this condition?
  • Should there be any activity or dietary changes?
  • Is it necessary to see a specialist?

Tip: Patients should feel comfortable asking about any concerns or fears.

Here’s a quick table to help with organization:

What to Bring Why It’s Helpful
List of symptoms Helps explain the current problem.
Medicine/supplement list Avoids medicine mix-ups.
Family medical history Detects possible risk factors.
List of questions Make sure you get the answers you need.

Planning ahead can make the visit go smoothly and ensure all concerns are addressed.

Questions the Doctor Might Ask

The healthcare provider will often have several questions to better understand the situation. They may ask:

  • When did the symptoms start?
  • Are the symptoms better or worse at some times?
  • What seems to make the symptoms change?
  • Do the symptoms come and go, or are they constant?
  • Has anyone close by had a cold, strep throat, or similar illness recently?
  • Is there a family history of strep diseases such as scarlet fever?
  • Were antibiotics taken, and if so, was the full course finished?

Preparing to answer these questions helps the provider make the right choices about tests and treatment. Keeping notes at home about symptom changes or factors that make things better or worse can be useful.

Doctors might also discuss any past treatments or health issues that could affect care decisions. They might ask about:

  • Recent hospital stays.
  • Past diagnoses related to heart, joint, or throat illnesses.
  • Side effects noticed from treatments or medicines.

Being ready to answer these questions, and having any important medical papers handy, can save time and help the appointment go faster.

Remember: Honest and complete information is important. The more details the healthcare provider has, the more accurate the evaluation and plan will be. If a cardiologist is involved because of heart issues, extra specific questions about heart health may come up.

Staying organized and open during the visit supports the best care and helps everyone work together to find solutions.
