Doctors at Sterling Hospitals have successfully treated a 14-year-old girl who developed a rare, life-threatening hyperinflammatory complication after contracting dengue. What initially appeared to be a standard case of viral fever rapidly escalated into secondary haemophagocytic lymphohistiocytosis (HLH)—a dangerous condition where the body’s immune system goes into overdrive, threatening vital organs such as the liver, kidneys, and brain.
The teenager, who has a history of bronchial asthma, initially sought treatment for high fever, severe headache, rapid heart rate, and breathlessness. After a PCR test confirmed dengue, her condition took a alarming turn when her platelet count plummeted from 3,50,000/μL to a critical 8,000/μL. Coupled with neurological symptoms, internal fluid leakage, and extensive skin rashes, physicians faced a race against time to prevent total multiorgan failure.
High-Risk Hyperinflammation Swiftly Intercepted
The breakthrough in the teenager's treatment came when diagnostic blood tests revealed her serum ferritin levels had spiked to nearly 8,000 ng/mL—a key indicator of severe internal inflammation. This crucial red flag allowed the medical team to immediately initiate targeted steroid therapy using dexamethasone alongside neurological care, platelet support, and carefully regulated fluid management.
The patient’s journey to recovery involved intense clinical management:
- Neurological Impact: The teenager suffered brief episodes of abnormal eye movements and brain dysfunction (encephalopathy), confirmed by an electroencephalogram (EEG), though brain scans showed no structural damage.
- Fluid Leakage: Fluid accumulated around her lungs and abdomen alongside heavy menstrual bleeding and rashes.
- Rapid Stabilization: By the fourth day of targeted treatment, her platelet count rebounded, ferritin levels normalized, and neurological symptoms fully resolved without needing a red-cell transfusion.
Dr Rajesh Mishra, Senior Consultant Intensivist and Internist at Sterling Hospitals, highlighted that dengue is far more complex than just a low platelet disease. "Dengue can severely affect the blood vessels and cause the immune system to overreact violently, leading to HLH and potential organ damage," he explained. He cautioned against routine or panic-driven platelet transfusions and excessive fluid administration, noting that both can cause unnecessary complications unless strictly required.
Young Adults Hit Hardest as Dengue Admissions Surge
The case comes amid a shifting trend in seasonal dengue infections across Ahmedabad. Data from Sterling Hospitals reveals a 4% increase in overall dengue inpatient admissions between June and September 2026 compared to the same period in 2025, rising from 99 to 103 cases.
Crucially, infections among young adults aged 24 to 28 have surged by 145.5%—jumping from 11 to 27 cases—and accounted for 26.2% of total hospital admissions for dengue this season. Medical experts urge early diagnostic testing, including serum ferritin and blood clotting parameters, to spot severe complications before they become fatal.
