Tuberculosis Treatment Springfield Lakes: Expert TB Care 2025
Concerned about tuberculosis exposure or symptoms? TB affects 1,200 Australians annually, with Queensland having higher rates. Early diagnosis and proper treatment can cure TB and prevent transmission to others.
Understanding Tuberculosis
Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis bacteria that primarily affects the lungs but can involve any organ system.
Types of TB
| Type | Description | Infectiousness | Treatment Duration |
|---|---|---|---|
| Latent TB | Infection without disease | Non-infectious | 3-9 months |
| Active pulmonary TB | Disease in lungs | Highly infectious | 6-9 months |
| Extrapulmonary TB | Disease outside lungs | Usually non-infectious | 6-12 months |
| Drug-resistant TB | Resistant to standard drugs | Variable | 18-24 months |
TB Transmission
- Airborne droplets – coughing, sneezing, speaking
- Close contact – prolonged exposure required
- Environmental factors – poor ventilation increases risk
- Host factors – immunosuppression increases susceptibility
- Not transmitted – through touching, sharing food/drinks
Risk Factors and Epidemiology
High-Risk Populations
| Population | Risk Level | Screening Frequency |
|---|---|---|
| Recent migrants | High | Within 6 months of arrival |
| Close contacts | Very high | Immediately after exposure |
| Immunocompromised | Very high | Annual screening |
| Healthcare workers | Moderate | Baseline + annual |
| Indigenous Australians | Higher than average | Regular screening |
Medical Risk Factors
- HIV infection – 20-30x increased risk
- Diabetes mellitus – 2-3x increased risk
- Chronic kidney disease – 10-25x increased risk
- Immunosuppressive therapy – 5-10x increased risk
- Malnutrition – 2-3x increased risk
- Alcohol use disorder – 2-3x increased risk
Social Risk Factors
- Crowded living conditions – dormitories, shelters
- Poverty – limited access to healthcare
- Recent incarceration – higher prevalence settings
- Substance use – injection drug use
- Homelessness – multiple risk factors combined
Symptoms and Clinical Presentation
Pulmonary TB Symptoms
- Persistent cough – >2-3 weeks duration
- Hemoptysis – blood in sputum (30-40% of cases)
- Chest pain – pleuritic or dull aching
- Dyspnea – progressive breathlessness
- Weight loss – unintentional, significant
Constitutional Symptoms
- Fever – low-grade, afternoon/evening
- Night sweats – drenching sweats
- Fatigue – profound tiredness
- Loss of appetite – anorexia
- Malaise – general feeling of illness
Extrapulmonary TB Sites
| Site | Frequency | Key Symptoms |
|---|---|---|
| Lymph nodes | 35% | Painless swelling |
| Pleura | 20% | Chest pain, dyspnea |
| Genitourinary | 15% | Dysuria, hematuria |
| Bone/joints | 10% | Pain, swelling |
| CNS | 5% | Headache, confusion |
| Abdomen | 5% | Pain, bowel symptoms |
Diagnosis and Testing
Screening Tests
Tuberculin Skin Test (TST):
- Injection – intradermal PPD injection
- Reading – 48-72 hours post-injection
- Interpretation – based on risk factors and induration size
- Limitations – affected by BCG vaccination, immunosuppression
Interferon-Gamma Release Assays (IGRAs):
- QuantiFERON-Gold – blood test for TB infection
- Advantages – not affected by BCG, single visit
- Limitations – expensive, false negatives in immunocompromised
- Preferred – for BCG-vaccinated individuals
Diagnostic Tests for Active TB
| Test | Sensitivity | Specificity | Time to Result |
|---|---|---|---|
| Sputum smear | 50-70% | >95% | 1-2 hours |
| Sputum culture | 80-85% | >98% | 2-8 weeks |
| Xpert MTB/RIF | 85-90% | >98% | 2 hours |
| Chest X-ray | 70-80% | Variable | Immediate |
Radiological Findings
- Upper lobe involvement – classic pattern
- Cavitation – suggests high bacillary load
- Pleural effusion – common in young adults
- Miliary pattern – disseminated TB
- Normal chest X-ray – 15% of pulmonary TB cases
Treatment and Management
First-Line Anti-TB Drugs
Standard Treatment Regimen (RIPE):
| Drug | Dose | Duration | Key Side Effects |
|---|---|---|---|
| Rifampin (R) | 10mg/kg daily | 6 months | Orange discoloration, hepatitis |
| Isoniazid (I) | 5mg/kg daily | 6 months | Hepatitis, peripheral neuropathy |
| Pyrazinamide (P) | 25mg/kg daily | 2 months | Hepatitis, hyperuricemia |
| Ethambutol (E) | 15mg/kg daily | 2 months | Optic neuritis |
Treatment Phases
Intensive Phase (2 months):
- Four drugs – RIPE daily
- Purpose – rapidly reduce bacterial load
- Monitoring – weekly for first 2 weeks, then fortnightly
- Sputum conversion – expected by 2-3 months
Continuation Phase (4 months):
- Two drugs – Rifampin + Isoniazid daily
- Purpose – eliminate dormant bacteria
- Monitoring – monthly clinic visits
- Completion – total 6 months treatment
Directly Observed Therapy (DOT)
- Definition – healthcare worker observes drug ingestion
- Indications – all TB patients in Australia
- Benefits – ensures adherence, monitors side effects
- Methods – clinic visits, home visits, video observation
- Documentation – treatment cards, electronic records
Treatment Monitoring
Clinical Monitoring:
- Symptom improvement – fever resolution within 2 weeks
- Weight gain – nutritional recovery
- Sputum conversion – negative smears/cultures
- Side effect assessment – regular symptom review
Laboratory Monitoring:
| Test | Frequency | Purpose |
|---|---|---|
| Liver function | Baseline, 2, 4, 8 weeks | Hepatotoxicity monitoring |
| Visual acuity | Monthly (if ethambutol) | Optic neuritis screening |
| Kidney function | Baseline, monthly | Renal toxicity |
| Sputum microscopy | Monthly until negative | Treatment response |
Drug-Resistant TB
Types of Drug Resistance
| Type | Definition | Treatment Duration |
|---|---|---|
| Mono-resistant | Resistant to one first-line drug | 6-9 months |
| Multi-drug resistant (MDR) | Resistant to rifampin + isoniazid | 18-24 months |
| Extensively drug-resistant (XDR) | MDR + fluoroquinolone + injectable | 18-24 months |
Second-Line Drugs
- Fluoroquinolones – levofloxacin, moxifloxacin
