How is the treatment regimen revised if a patient under SLOR FQ - S shows resistance in LPA testing?

The correct answer involves consulting with the TB MAC (Tuberculosis Medical Advisory Committee) because this step ensures that treatment decisions are made based on expert recommendations and the latest evidence on managing drug-resistant tuberculosis.

When a patient shows resistance in LPA (Line Probe Assay) testing, it indicates that the standard treatment regimen may not be effective. The involvement of the TB MAC is crucial as they can provide tailored advice and the best course of action, which may include endorsing specific second-line therapies or alternative regimens based on the patient's resistance profile.

Addressing the other options, halting all medications would not be appropriate, as this could lead to treatment failure and the risk of further disease transmission. Switching to second-line therapy only might not consider the complexity of the patient's resistance, and therefore a more comprehensive approach is required. Continuing current therapy without adjusting for resistance would likely result in ineffective treatment and progression of the disease.
