RESUMO
BACKGROUND: One of the most severe forms of TB, disseminated TB (dTB) is associated with significant mortality. A retrospective study was undertaken to assess the proportion of dTB among inpatient deaths and to describe the pathological spectrum of lesions. Associated comorbidities and missed dTB cases ante-mortem were also sought.METHODS: Data on autopsy-confirmed cases of dTB from over three decades (1988-2016) obtained from the departmental archives of the Post Graduate Institute of Medical Education and Research, Chandigarh, India, were reviewed for clinical details, as well as gross and histopathological findings. The proportion of autopsy-confirmed dTB were reported.RESULTS: During this period, a total of 243 autopsy-confirmed cases were retrieved. The organs most commonly involved in these cases were the lungs (90.1%), followed by the liver (72%), spleen (44%), kidneys (37%), bone marrow (17%), adrenals (12.2%), intestine (11.4%), pancreas (8.5%) and reproductive organs (6.9%). The brain was involved in 73.3% cases. In one third of cases, the diagnosis of TB was not suspected ante-mortem. Comorbid conditions were noted in 36.2% cases.CONCLUSION: A significant burden of dTB was noted among hospital inpatient deaths. Due to multi-organ involvement, dTB has atypical symptoms and may remain undiagnosed ante-mortem. Increased awareness and robust screening of TB cases are mandatory, particularly in patients with underlying comorbidities.
