17-Year-Old Recovers From Multi-Organ Failure Triggered By Enteric Fever At Apollo Speciality Hospitals, Teynampet.

Chennai, 29th of September, 2026 : A 17-year-old college student has made a successful recovery after enteric fever triggered a rare immune-related complication that progressed to multi-organ failure, requiring intensive care and mechanical ventilation at Apollo Speciality Hospitals, Teynampet.

The teenager was admitted with high-grade fever, vomiting, loose stools, nasal bleeding and breathlessness and was initially diagnosed with enteric fever. Despite treatment, his condition worsened, with a sharp fall in haemoglobin, white blood cells and platelets, along with deteriorating kidney and liver function and markedly elevated ferritin and inflammatory markers.

The persistent fever, falling blood counts and increasing inflammation raised suspicion of secondary Hemophagocytic Lymphohistiocytosis (HLH) — an uncommon condition in which excessive immune activation causes widespread inflammation and can damage multiple organs. A bone marrow examination showed haemophagocytic activity, supporting the diagnosis of enteric fever-associated secondary HLH.

His condition subsequently progressed to Disseminated Intravascular Coagulation (DIC), causing severe clotting abnormalities, followed by kidney and liver dysfunction. He also developed Acute Respiratory Distress Syndrome (ARDS) and required mechanical ventilation.

Multidisciplinary team approach

Recognising the complexity and rapidly evolving nature of the condition, the patient was managed by an expert multidisciplinary team at Apollo Speciality Hospitals, Teynampet, with coordinated care across Internal Medicine, Critical Care, Pulmonary Medicine, Haemato Oncology and Infectious Diseases, supported by nursing and allied healthcare teams.

The clinical team included:

* Dr Syed Hafeezullah, Consultant – Internal Medicine

* Dr Kannaiyan R, Senior Consultant – Internal Medicine

* Dr Ashwin K. Mani, Senior Consultant in Pulmonary Medicine and Clinical Lead for Critical Care

* Dr Srikanth Muralikrishnan, Senior Consultant, Hemato Oncology

* Dr Abdul Ghafur, Senior Consultant – Infectious Disease

The doctors treated both the underlying infection and the excessive inflammatory response. Treatment included intravenous antibiotics, corticosteroids, blood-product support and intensive care management for multi-organ dysfunction.

With coordinated multidisciplinary intervention, the patient’s condition gradually improved. His respiratory function recovered, allowing him to be weaned off the ventilator, while his vital parameters and laboratory values stabilised. He was subsequently shifted from intensive care to the ward for physiotherapy and supportive care.

The patient has since been discharged from Apollo Speciality Hospitals, Teynampet. He is clinically stable, breathing independently, ambulatory and in good health, with appropriate follow-up advised.

The Internal Medicine team at Apollo Speciality Hospitals, Teynampet, said, “The patient initially presented with features suggestive of a significant infection. However, the persistence of fever, progressive reduction in all three blood cell lines and markedly elevated ferritin levels indicated that an additional underlying process could be contributing to his deterioration. This prompted further evaluation for HLH. The bone marrow findings supported the diagnosis, enabling the multidisciplinary team to address both the underlying infection and the associated hyperinflammatory response.”

The treating doctors highlighted that secondary HLH can be difficult to identify because its early features may resemble severe infection or sepsis. Persistent fever accompanied by falling blood counts, bleeding, breathlessness, reduced urine output, altered consciousness or other signs of organ dysfunction warrants urgent medical evaluation.

While enteric fever does not commonly lead to HLH, infections can, in rare cases, trigger an exaggerated immune response. In this case, the expert multidisciplinary team at Apollo Speciality Hospitals, Teynampet, worked in close coordination to identify the evolving complications, manage the underlying infection and control the hyperinflammatory response, ultimately helping the 17-year-old patient recover and return home in stable health.

Mr. Harshad Reddy, Director – Group Oncology and International Business, Apollo Hospitals, said, “This case is a reminder of how a common infection can, in rare instances, evolve into a complex, multi-system illness. It reflects the importance of early recognition and close coordination between specialities, which remains central to how we approach critical and complex care across our network.”

Mr. Karan Puri, CEO, Apollo Speciality Hospitals, Teynampet, said, “This case required the clinical teams to respond to a rapidly changing situation and address both the infection and its complications. The coordinated involvement of critical care, haematology, infectious diseases and general medicine was important in managing the patient’s recovery. The successful outcome reflects the strength of multidisciplinary care available at Apollo Speciality Hospitals, Teynampet.”

The case highlights the importance of early recognition, timely intervention and seamless multidisciplinary coordination in managing rare and life-threatening complications of infections.
