A lady diagnosed with sputum positive TB. Best management is:
**Core Concept**
The management of sputum positive TB involves a combination of antitubercular medications to effectively kill the bacteria, prevent drug resistance, and minimize the risk of transmission to others. The World Health Organization (WHO) recommends a standardized treatment regimen for all forms of TB.
**Why the Correct Answer is Right**
The standard treatment for sputum positive TB involves a combination of four first-line antitubercular drugs: Isoniazid (H), Rifampicin (R), Pyrazinamide (Z), and Ethambutol (E). This regimen is often abbreviated as HRZE. The combination of these drugs targets different aspects of the TB bacteria's life cycle, making it more effective than monotherapy. Rifampicin and Isoniazid are particularly crucial, as they have a synergistic effect in killing the bacteria. The duration of treatment typically lasts for 6 months, with the first two months involving daily administration of HRZE, followed by continuation phase where only H and R are given for the next 4 months.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incomplete and does not specify the combination of drugs.
**Option B:** This option might be referring to a treatment regimen for drug-resistant TB, which would involve a different combination of drugs.
**Option C:** This option is not a standardized treatment regimen for sputum positive TB.
**Clinical Pearl / High-Yield Fact**
When initiating TB treatment, it's essential to remember the "4 Cs" of TB treatment: Combine (multiple drugs), Continue (for the full duration), Complete (all doses), and Confirm (through regular sputum smear microscopy and/or culture).
**Correct Answer: D. HRZE (Isoniazid, Rifampicin, Pyrazinamide, and Ethambutol)**
