Disease Overview：Cough Variant Asthma（CVA）
Cough Variant Asthma (CVA) is a phenotypic subtype of asthma characterized predominantly by chronic, non-productive cough lasting more than eight weeks, without classic bronchospastic symptoms such as wheezing or dyspnea. It results from airway hyperresponsiveness and eosinophilic inflammation, often triggered by allergens, viral infections, or environmental irritants. Diagnosis requires exclusion of other causes—such as GERD, postnasal drip, or chronic bronchitis—and confirmation via bronchial provocation testing (e.g., methacholine challenge) or therapeutic response to inhaled corticosteroids (ICS) and long-acting beta-agonists (LABA). Untreated CVA may progress to classic asthma in up to 30% of cases, underscoring the importance of early, targeted intervention.
China offers distinct advantages for CVA management: leading respiratory centers—such as Peking Union Medical College Hospital and Shanghai Ruijin Hospital—employ advanced pulmonary function labs, fractional exhaled nitric oxide (FeNO) monitoring, and high-resolution CT for differential diagnosis. Clinical protocols align with GINA guidelines, and real-world data show >85% symptom control rates within 12 weeks using personalized ICS/LABA regimens. Treatment costs are typically 40–60% lower than in the US or Western Europe, with no compromise in evidence-based care. As a dedicated medical tourism agency, we facilitate seamless access to these accredited institutions—handling hospital referrals, visa support, multilingual consultations, and transparent, all-inclusive pricing. Our patient coordinators accompany individuals throughout diagnosis, therapy initiation, and follow-up planning, ensuring continuity and confidence in outcomes.

Treatment Options & Itemized Cost Breakdown: Cough Variant Asthma (CVA)
Non-Surgical / Conservative / Medication Management
*Target Criteria:* Confirmed diagnosis via bronchial provocation test (methacholine/histamine), FeNO ≥25 ppb, or documented bronchodilator response; no structural airway obstruction or alternative etiology (e.g., GERD, postnasal drip).
- •Step 1: Low-Dose ICS (Budesonide/Formoterol DPI)
- Includes: 2 inhalers (120 doses each), spacer device (¥45/$6), pharmacist counseling (¥0 — bundled)
- •Diagnostic & Monitoring Exams (per episode)
- Fractional Exhaled Nitric Oxide (FeNO): ¥120 ($17) - Chest HRCT (if atypical presentation): ¥480 ($67) - Total baseline workup: ¥860 ($120)
- •Add-on Therapy (Moderate-severe or ICS-refractory)
- High-dose ICS/LABA (e.g., Salmeterol/Fluticasone DPI): 3-month supply ¥620 ($87)
Surgical / Procedural / Interventional Options
*Eligibility Criteria:* Documented severe, refractory CVA unresponsive to ≥6 months of high-dose ICS/LABA + LTRA, with objective evidence of eosinophilic airway inflammation (sputum eosinophils ≥3% or blood eosinophils ≥300/μL), and exclusion of vocal cord dysfunction or chronic cough due to non-asthmatic causes.
- •Bronchial Thermoplasty (BT)
- Preoperative: PFT + DLCO (¥180/$25), sputum eosinophil count (¥150/$21), CT angiography (¥520/$73), anesthesiology evaluation (¥300/$42) → Total pre-op: ¥1,150 ($161) - *Note:* BT is performed in respiratory endoscopy suite under conscious sedation; not indicated for mild-moderate CVA.
Special / Complex Condition Management
- •CVA with Severe Comorbid GERD: Esophageal pH-impedance monitoring (¥1,200/$168) + 3-month high-dose PPI (¥240/$34); total add-on: ¥1,440 ($202)
- •CVA with Obesity (BMI ≥30): Structured weight-loss program (respiratory-nutrition co-management): ¥1,800 ($252) for 12 weeks (includes 4 visits, spirometry tracking, dietary planning)
- •Pediatric CVA (<12 years): Nebulized budesonide (3-month course): ¥420 ($59) + pediatric-specific FeNO/PFT (¥220/$31)
Quick Selection Guide
- •Children (5–12 y), Mild CVA, Budget-Conscious: Start with low-dose ICS DPI + FeNO monitoring → Total Year 1: ~$190
- •Adults (18–65 y), Moderate CVA, Comorbid GERD: ICS/LABA + PPI + pH monitoring → Total Year 1: ~$320
- •Adults (>50 y), Severe Refractory CVA, No Comorbidities: Bronchial thermoplasty pathway → Total Year 1 (incl. pre-op, procedure, 3-month follow-up): ~$6,500
- •Elderly (>70 y) or Frail Patients: Low-dose ICS + LTRA only; avoid BT or high-dose regimens → Total Year 1: ~$150
Pricing & Service Differences: International / VIP Dept vs. Regular Clinic
International Medical Services (IMS / VIP Departments) at Grade-3A public hospitals and private international clinics operate under self-regulated VIP fee schedules. Fees are higher than standard public clinics (which are subsidized solely for domestic citizens and do not accept overseas insurances). In exchange, international patients receive 6 exclusive medical privileges:
