Summary

Diagnosing miliary tuberculosis (TB) is challenging, especially cryptic forms. Delayed diagnosis and treatment of TB in Finland pose risks in healthcare and at autopsy.

Area of Science:

  • Medical research
  • Infectious diseases
  • Public health

Background:

  • Miliary tuberculosis (TB) is a severe disseminated form of TB.
  • Accurate and timely diagnosis of miliary TB is crucial for effective patient management and public health.
  • Autopsy data provides valuable insights into diagnostic challenges of fatal TB cases.

Purpose of the Study:

  • To analyze autopsy-confirmed miliary tuberculosis deaths in Finland.
  • To identify factors contributing to diagnostic delays and improve diagnostic strategies for miliary TB.

Main Methods:

  • Analysis of autopsy-confirmed miliary tuberculosis deaths in Finland.
  • Examination of mortality statistics to identify miliary TB cases.
  • Review of medical records and chest X-ray findings of autopsied patients.

  • Classification of cases into 'overt' and 'cryptic' disease groups.

    • Main Results:

    • 114 overt and 140 cryptic miliary TB cases were identified, with a majority of females in both groups.
    • No significant differences were observed in previous TB history, predisposing factors, or symptoms between overt and cryptic groups.
    • Suspicion of TB was recorded in 86% of overt cases versus 53% of cryptic cases.
    • Chemotherapy was administered to 50% of overt cases but only 25% of cryptic cases.
    • Autopsies were performed without suspicion of TB in one-third of all cases, particularly in the cryptic group.

    Conclusions:

    • Suspicion of miliary tuberculosis, especially the cryptic form, arose too infrequently.
    • Delayed diagnosis and inadequate chemotherapy administration were noted.
    • Lack of timely suspicion and diagnosis increases risks in healthcare settings and during post-mortem examinations.
