TB Treatment Started on X‑Ray Alone Risks Misdiagnosis
Lucknow, July 24 – Health experts caution that initiating tuberculosis (TB) medication solely on the basis of a chest X‑ray and vague symptoms can expose patients to serious danger. At the Civil Hospital in the state capital, numerous cases are reported where anti‑TB drugs are prescribed without laboratory confirmation, while many genuine TB patients continue treatment for unrelated lung conditions.
Specialists stress that a reliable TB diagnosis requires a combination of investigations such as sputum microscopy, CB‑NAAT, GeneXpert, CT scans, and a thorough review of the patient’s medical history, alongside the X‑ray.
A 46‑year‑old resident from Ahimamau, who complained of persistent cough, breathlessness, and weight loss, was given TB tablets after a private doctor noticed shadows on his X‑ray. After a week of medication, his condition showed no improvement.
Further examinations at the Civil Hospital revealed that the patient actually suffered from a lung nodule, not TB. The anti‑TB regimen was immediately stopped.
Senior pulmonologist Dr. Ashutosh Dubey explains that not every opacity on an X‑ray indicates TB. Lung cancer, nodules, asthma, bronchitis and TB can appear similar radiographically. Approximately 30 % of cases diagnosed only by X‑ray prove to be incorrect.
The hospital treats 150‑200 new TB cases each month, including 2‑3 multidrug‑resistant (MDR) cases. Uttar Pradesh registers 15‑17 000 MDR‑TB patients annually. Early detection and complete therapy have now pushed the cure rate above 90 % and lowered incidence to less than 200 per lakh population.
An untreated TB patient can infect about 15 others per year. Incomplete treatment may give rise to MDR‑TB, and if MDR treatment is abandoned, extensively drug‑resistant (XDR) TB can develop, requiring up to two years of therapy.
Dubey also described the four phenotypes of Mycobacterium tuberculosis – rapid growers, intracellular, cell‑wall, and dormant bacilli – noting that standard drugs eliminate the first three but spare the dormant form, which can reactivate when immunity wanes.
TB bacteria survive six months in cold, dark, moist settings and up to a month in sunlight. Transmission occurs through coughing or sneezing, especially in close, unmasked contact lasting half an hour or more.
The doctor highlighted additional risk factors such as smoking, substance abuse, malnutrition, junk food, weakened immunity, diabetes, HIV, cancer, anemia, and old age. Overcrowded, damp slums in districts like Agra, Firozabad, Kanpur, Varanasi, Lucknow and Prayagraj record the highest case numbers.
The state government provides a monthly nutrition allowance of ₹1,000 to registered TB patients. Prompt detection, testing and uninterrupted treatment remain the most effective strategy to eradicate the disease.
At the Institute of Medical Sciences, a cutting‑edge endobronchial ultrasound (EBUS) unit now offers live imaging of the airways through a thin oral tube, enabling early and accurate identification of TB, lung cancer and mediastinal lymph‑node disorders without surgical intrusion.
