Abstract:
Reports of histopathological findings in a patient infected with H1N1 influenza virus are limited in the literature, although many deaths have occurred because of this viral infection. In an otherwise healthy individual with no underlying co-morbid conditions, this virus passes off as a very mild disease. However, it can be fatal in the presence of underlying risk factors. Here, we present the autopsy findings of a patient who died of H1N1 infection, but who was apparently healthy with no predisposing ailments. The autopsy revealed chronic kidney disease and caseating granulomatous lymphadenitis in addition to the known classical diffuse alveolar damage picture seen in this condition. These underlying co-morbidities may provide greater insight and a better understanding of this infection.
Insights
Autopsy revealed unexpected chronic kidney disease and lymphadenitis in a fatal H1N1 influenza case. These findings in an apparently healthy individual highlight potential underlying factors in severe H1N1 infection.
Area of Science:
- Pathology
- Virology
- Nephrology
Background:
- Limited histopathological data exists for fatal H1N1 influenza cases.
- H1N1 influenza typically presents mildly in healthy individuals but can be severe with co-morbidities.
Observation:
- Autopsy findings in a fatal H1N1 influenza case are presented.
- The patient was apparently healthy with no known predisposing conditions.
Findings:
- Diffuse alveolar damage, characteristic of H1N1 influenza, was observed.
- Unexpected findings included chronic kidney disease and caseating granulomatous lymphadenitis.
Implications:
- These co-morbidities may offer new insights into severe H1N1 influenza pathogenesis.
- Understanding underlying conditions is crucial for managing severe H1N1 influenza cases.
