Definition of Intermittent Fever

  Definition of Intermittent Fever

   Intermittent fever is a type of fever that occurs in cycles or episodes. (Health)

      In this condition, the body temperature rises above normal, returns to baseline or subnormal levels after a specific period, and repeats the cycle.

       It is often associated with infections and systemic diseases, particularly those caused by parasites, bacteria, or chronic illnesses.

       Causes of Intermittent Fever

       Intermittent fever can result from various underlying conditions, including:

        Malaria: Caused by Plasmodium species, often associated with fevers recurring every 48-72 hours.

        Typhoid fever: Caused by Salmonella typhoid bacteria.

         Tuberculosis: A chronic bacterial infection that can cause fluctuating fever.

          Brucellosis: An infection caused by Brucella bacteria, leading to undulating fever patterns.

          Sepsis: A systemic infection that can cause irregular fever spikes.

          Autoimmune disorders: Diseases like lupus or rheumatoid arthritis may present with intermittent fever due to chronic inflammation.

Symptoms of Intermittent Fever

      The symptoms of intermittent fever may vary depending on the underlying cause, but some common features include:

Core Symptoms

     1. Temperature fluctuations: Fever spikes followed by periods of normal or subnormal temperature.

      2. Chills and rigors: Sudden onset of shivering, often preceding fever.

      3. Sweating: Excessive perspiration as the fever subsides.

      4. General malaise: Fatigue, weakness, and a lack of energy.

      5. Headache: Often accompanies fever episodes.

Additional Symptoms by Cause

     Malaria:

      Profuse sweating during defervescence.

      Muscle aches and nausea.

      Anemia and splenomegaly in prolonged cases.

     Typhoid Fever:

      Abdominal discomfort and diarrhea or constipation.

      Rose-colored spots on the trunk.

     Tuberculosis:

      Persistent cough (with or without blood).

      Weight loss and night sweats.

     Sepsis:

      Rapid heartbeat and breathing.

      Confusion or altered mental state.

Diagnosis

        Identifying intermittent fever involves clinical examination, patient history, and diagnostic tests:

       1. History-taking:

         Documenting the fever pattern, duration, and associated symptoms.

         Travel history (to endemic areas for malaria or typhoid).

        2. Physical Examination:

         Checking for signs of systemic infection, such as lymphadenopathy or organ enlargement.

        3. Laboratory Tests:

          Complete blood count (CBC): To detect anemia, leukocytosis, or thrombocytopenia.

          Blood cultures: To identify bacterial infections like typhoid.

          Malaria parasite smear or rapid antigen test: For diagnosing malaria.

          Tuberculin skin test (Mantoux test) or chest X-ray: For tuberculosis.

          C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR): For inflammatory markers.

         4. Imaging Studies:

          Ultrasound or CT scan: To evaluate abdominal organs.

          Chest imaging: To identify respiratory infections like TB.

Treatment of Intermittent Fever

          The treatment of intermittent fever depends on the underlying cause. Addressing the root cause is critical to resolving the condition. Below is a breakdown of treatment options for common causes:

        1. Malaria

        Antimalarial drugs:

         Chloroquine or hydroxy chloroquine for Plasmodium vivax.

          Artemisinin-based combination therapies (ACTs) for Plasmodium falciparum.

        Supportive care:

         Hydration, fever management (using antipyretics like paracetamol).

        2. Typhoid Fever

Antibiotics:

         Ciprofloxacin, ceftriaxone, or azithromycin, depending on resistance patterns.

        Hydration:

         Oral or intravenous fluids to combat dehydration.

         Dietary adjustments:

          Soft, easily digestible foods during recovery.

         3. Tuberculosis

        Antitubercular therapy (ATT):

         A combination of isoniazid, rifampin, pyrazinamide, and ethambutol (initial phase).

         The continuation phase includes isoniazid and rifampin.

        Nutritional support:

         High-protein diet and vitamin supplementation to enhance recovery.

        4. Sepsis

         Antibiotics:

           Broad-spectrum antibiotics are administered initially and tailored later based on culture results.

         Intensive care:

        Oxygen therapy, vasopressors, and fluid resuscitation for shock.

         Monitoring:

          Continuous monitoring of vital signs and organ function.

         5. Autoimmune Disorders

         Immunosuppressive therapy:

          Corticosteroids or disease-modifying antirheumatic drugs (DMARDs).

         Supportive therapy:

          Physical therapy and pain management.

Symptomatic Treatment

          Regardless of the cause, symptomatic treatment can help manage fever-related discomfort:

        Antipyretics:

         Paracetamol or ibuprofen to reduce fever and relieve pain.

        Hydration:

          Encouraging fluids to prevent dehydration.

        Rest:

         Adequate rest to conserve energy.

Side Effects of Treatment

         Treatments for intermittent fever can sometimes lead to side effects, which vary based on the medications or therapies used.

        1. Antimalarial Drugs

         Chloroquine: May cause itching, nausea, and visual disturbances.

       ACTs: Can lead to headache, dizziness, or gastrointestinal upset.

        2. Antibiotics

Fluoroquinolones (e.g., ciprofloxacin):  Risk of tendonitis or gastrointestinal issues.

    Ceftriaxone: Can cause allergic reactions or diarrhea.

     Azithromycin: Possible nausea and abdominal discomfort.

      3. Antitubercular Therapy

       Isoniazid: This may cause liver toxicity or peripheral neuropathy.

       Rifampin: Commonly causes orange discoloration of bodily fluids and gastrointestinal upset.

       Pyrazinamide: This can lead to joint pain or hepatotoxicity.

       4. Sepsis Treatment

       Broad-spectrum antibiotics: Risk of antibiotic resistance or secondary infections like Clostridium difficile.

        Fluid resuscitation: Overuse may lead to pulmonary edema.

        Vasopressors: Can cause reduced blood flow to peripheral tissues.

         5. Immunosuppressive Therapy

        Corticosteroids: Risk of weight gain, osteoporosis, and increased susceptibility to infections.

         DMARDs: May cause nausea, liver dysfunction, or blood count abnormalities.

General Side Effects

       Fever medications (paracetamol/ibuprofen):

         Overuse can lead to liver or kidney damage.

        Hydration therapy:

         Excessive intravenous fluids may result in fluid overload.

Prevention of Intermittent Fever

         Preventing intermittent fever involves addressing its root causes and practicing good hygiene:

       1. Malaria Prevention:

        Use of insecticide-treated bed nets.

         Avoiding mosquito bites with repellents and protective clothing.

         Prophylactic antimalarial medication when traveling to endemic regions.

       2. Typhoid Prevention:

         Drinking clean, boiled, or filtered water.

         Ensuring proper food hygiene.

         Vaccination in high-risk areas.

        3. Tuberculosis Prevention:

         Timely vaccination with the Bacillus Calmette-Guérin (BCG) vaccine.

         Avoiding close contact with infected individuals.

        4. Sepsis Prevention:

         Prompt treatment of localized infections.

         Vaccination against pneumonia and meningitis.

       5. General Hygiene:

         Regular handwashing.

         Safe disposal of waste.

        Maintaining clean surroundings.

         Prognosis

        The outcome of intermittent fever depends on timely diagnosis and appropriate treatment. 

        While most cases can be managed effectively, delays in treatment may lead to complications, such as:

       Malaria: Cerebral malaria, anemia, or organ failure.

       Typhoid fever: Intestinal perforation or chronic carrier state.

       Tuberculosis: Lung scarring or dissemination to other organs.

        Sepsis: Multiorgan failure or septic shock.
