Case Presentation

A 41-year-old male business professional presented to the clinic with a several-day history of feeling unwell, accompanied by subjective symptoms of bitterness in the mouth and a sensation of heat in his body resembling fever. He reported partial relief after taking herbal medication but noted persistent malaise. The patient has no significant past medical or surgical history, is not on any prescribed medications, and has no known drug allergies. He does not smoke or consume alcohol and is able to perform activities of daily living without limitations.

Clinical Examination

Vital Signs:

• Blood Pressure: 122/81 mmHg
• Pulse: 84 beats per minute
• Temperature: 37
• Respiratory Rate: Not documented
• BMI: 18.52 (borderline low)

Physical Examination Findings: Warm to touch, suggesting possible subclinical fever. Lungs clear to auscultation bilaterally. Cardiovascular system shows normal heart sounds. Abdomen soft, non-tender, with no palpable masses. Skin normal, gait normal.

Laboratory and Radiological Findings

Additional Investigations Recommended: Full Blood Count (FBC), Basic Urine Examination (BUE), Liver Function Tests (LFT), Lipid Profile, Prostate-Specific Antigen (PSA), Glycated Hemoglobin (HbA1c).

Differential Diagnosis

• Acute Malaria (confirmed)
• Acute Typhoid Fever (confirmed)
• Iron Deficiency Anemia (microcytic normochromic anemia)
• Other Infectious Causes (less likely)
• Liver Dysfunction (monitoring required)

Diagnosis

• Acute Malaria
• Acute Typhoid Fever
• Iron Deficiency Anemia

Treatment Plan

• Malaria Management: Artemether/Lumefantrine (Coartem) prescribed for 3 days.
• Typhoid Fever Management: Levofloxacin 500 mg once daily for 10 days.
• Anemia Management: Feroglobin capsules one daily.
• Monitoring: Follow-up tests including FBC, BUE, LFT, lipids, PSA, HbA1c.

Discussion

Malaria and typhoid are common febrile illnesses in tropical regions. Co-infection is well-documented and poses diagnostic challenges. Iron supplementation addresses anemia, while monitoring liver function ensures safety from potential hepatotoxicity.

Conclusion

This case underscores the diagnostic complexity and therapeutic challenges associated with concurrent infections of malaria, typhoid fever, and iron deficiency anemia in a 40-year-old male. Such co-infections are particularly prevalent in regions where these diseases are endemic, necessitating a high index of suspicion among healthcare providers. The patient's persistent fever and hematological abnormalities, including anemia and thrombocytopenia, highlight the intricate interplay between these infections. Studies have demonstrated that malaria can predispose individuals to invasive bacterial infections, notably Salmonella species, due to malaria-induced hemolysis and immune modulation. This phenomenon is well-documented in a case report where a traveler returning from Nigeria developed concomitant Plasmodium falciparum malaria and non-typhoidal Salmonella bacteremia. Moreover, hematological abnormalities such as anemia and thrombocytopenia are common in both malaria and typhoid infections. A study conducted in the Tamale Metropolis of Ghana found significant associations between these cytopenias and malaria, particularly among middle-aged individuals.Additionally, malaria has been linked to immune-mediated hemolytic anemia, further complicating the clinical picture. This case emphasizes the importance of comprehensive diagnostic evaluations and a multidisciplinary approach to manage such co-infections effectively. Timely identification and treatment are crucial to prevent severe complications and improve patient outcomes.
