Title: Morbidly obese patient with non-alcoholic steatohepatitis-related cirrhosis who died from sepsis caused by dental infection of Porphyromonas gingivalis: A case report.
Abstract: Non-alcoholic steatohepatitis (NASH) is associated with increased risks of developing lifestyle-related diseases including type 2 diabetes, cardiovascular disease and cerebral vessel disease. While the two-hit hypothesis and, recently, multiple parallel hits hypothesis of NASH pathogenesis were proposed, further details have not emerged. Recently, dental infection of Porphyromonas gingivalis (P. gingivalis) has been reported as a critical risk factor for NASH progression, which acts as multiple parallel hits to induce inflammation and fibrogenic responses in steatosis. We describe here a 54-year-old woman who died from sepsis and was diagnosed with NASH. Briefly, her body mass index (BMI) at the age of 35 years old had been 25.6 kg/m(2) , but she became obese after withdrawing into her home at the age of 45 years. Severe obesity continued over 19 years without diabetes mellitus. She was admitted to our hospital due to a sudden disturbance of consciousness. On admission, her BMI was 48.5 kg/m(2) . Computed tomography revealed cirrhotic liver with massive ascites, and laboratory data indicated increased inflammatory responses, renal failure and C grade Child-Pugh classification, suggesting the diagnosis of sepsis. Also, severe periodontal disease was present, because the patient's front teeth fell out easily during intubation. Although the focus of infection was not specified, the oral flora Parvimonas micra, a periodontal pathogen, was detected in venous blood. In spite of intensive care including artificial respiration management and continuous hemodiafiltration, she died on the 43rd day after admission. Surprisingly, P. gingivalis was detected in her hepatocytes. This case may represent the significance of P. gingivalis in the progress to cirrhosis in NASH patients.
