Insights
Tuberculosis (TB) can cause rare infectious renal artery stenosis in children, leading to severe hypertension. Early diagnosis and preventive therapy are crucial to avoid serious complications like stroke and malnutrition.
Area of Science:
- Pediatric Nephrology
- Infectious Diseases
- Cardiology
Background:
- Renal artery stenosis is a frequent cause of pediatric hypertension.
- Infectious etiologies of renal artery stenosis are uncommon.
- Diagnosing tuberculosis (TB) in children presents significant challenges, often leading to delayed identification.
Observation:
- A 4-year-old girl presented with loss of consciousness and seizures.
- She had severe acute malnutrition, TB symptoms, and contact with smear-positive TB adults.
- Her blood pressure was recorded at 200/140 mmHg.
Findings:
- The patient was diagnosed with disseminated TB, left renal artery stenosis, severe hypertension, cardiomegaly, upper gastrointestinal bleeding, stroke, and severe malnutrition.
- Diagnosis was confirmed via head CT scan, MRI, and renal ultrasound.
- While antituberculosis drugs and supportive care resolved most symptoms, hypertension persisted, requiring surgical intervention for renal stenosis.
Implications:
- Atypical presentations of TB necessitate consideration, particularly with a history of close contact.
- Timely tuberculosis preventive therapy could have potentially averted the severe complications observed in this case.
Background:
Renal artery stenosis is a common cause of hypertension in children; however, infectious causes of renal artery stenosis are rare. Diagnosis of TB in children is challenging, causing delay in diagnosis.
Case Presentation:
We report a case of a 4-year-old girl who was presented with loss of consciousness and seizure of one day duration. The patient had severe acute malnutrition, symptom complex of TB and contact with adults having smear positive tuberculosis. Subsequently, her blood pressure was 200/140 mmhg. The patient was diagnosed with disseminated TB with left renal artery stenosis, severe hypertension, cardiomegaly, upper gastrointestinal bleeding, stroke and severe malnutrition. Diagnosis was confirmed with head CT scan, MRI and ultrasound of the kidneys. The patient was on antituberculosis drugs, prednisolone, nifedipine, furosemide, antiepileptic drugs and nutritional therapy. After treatment with antituberculosis drugs and other supportive care all the symptoms subsided, while the hypertension was not controlled, necessitating surgical intervention for the left renal stenosis.
Conclusion:
Atypical presentations of TB have to be considered especially when there is a strong contact history. Tuberculosis preventive therapy may have prevented all the complications, had it been given the moment the index cases were diagnosed.
