Abstract:
Background
Tuberculosis is a major health problem in Saudi Arabia and developing countries. Understanding the epidemiology of the disease helps in its early identification and prevention. This study was conducted to evaluate the pattern and clinical presentation of Mycobacterium tuberculosis (MTB) among Saudi nationals. Materials And Methods
We reviewed the clinical and laboratory records of 147 patients with proven cultural diagnosis of MTB attending King Khalid National Guard Hospital (KKNGH)، Jeddah، Saudi Arabia between June 1993 and June 1999 and also studied the symptoms and clinical pattern of the disease. Results
Our study demonstrated that MTB affected mainly young adults in their second and third decades. There was no significant difference in the prevalence of the disease between the genders، though slightly more males (75/147، 51%) were affected compared to females (72/147، 49%). There was a high incidence of extra-pulmonary TB (36. 6%)، with lymph node involvement being the most common extra-pulmonary site (27%). Although the most common symptoms were chronic cough (51. 7%)، fever (46. 3%) and weight loss (41. 5%)، these symptoms seem to occur less frequently in patients with TB than previously reported. There was an alarming high prevalence of drug resistant MTB (15% for isoniazid، 9. 5% for rifampicin، 8. 2% for pyrazinamide، 15. 6% for ethambutol، and 9. 5% for multi-drug resistant). Conclusion
The presence of classical symptoms of MTB (cough، fever، weight loss) was less frequent than expected suggesting atypical presentation of the disease may be more common than what was previously held. There was a high incidence of extra pulmonary TB in our study، lymph node involvement being the most common. Physicians working in Saudi Arabia should be aware of the unusual presentation of the disease. The high prevalence of drug resistant MTB emphasizes the importance of performing culture and sensitivity tests for MTB in all new cases. (Tanaffos 2005; 4(14): 37-42)Language:
