Case Summary: Effective Treatment of Pediatric Acute Bronchitis

A previously healthy 8-year-old boy presented with a persistent cough that had worsened over the course of one week. Initial home treatments failed to provide relief, prompting his parents to seek medical attention. After thorough clinical evaluation and diagnostic testing, he was diagnosed with acute bronchitis, likely caused by a Mycoplasma pneumoniae infection. The treatment plan included azithromycin dry suspension combined with supportive herbal therapy. Within two weeks, the child showed significant improvement—his symptoms resolved completely, and follow-up tests confirmed full recovery.

Patient Profile & Clinical Overview

Gender/Age: Male, 8 years oldDiagnosis: Acute bronchitis due to Mycoplasma infectionHospital: Third Xiangya Hospital, Central South UniversityDate of Visit: April 2022Treatment Plan: Oral azithromycin dry suspension + Huanglong Cough-Relief GranulesDuration: Outpatient care for 14 daysOutcome: Complete symptom resolution; normal blood test results upon follow-up

Initial Consultation: Recognizing the Signs

The child's parents reported that he began experiencing frequent dry coughing approximately seven days before the clinic visit. At home, they had administered cefadroxil granules and Zibei Cough Relief Granules without noticeable improvement. Two days prior to the appointment, his condition deteriorated—he became more fatigued and developed low-grade fever symptoms, increasing parental concern.

Upon physical examination, the patient's vital signs were stable: temperature 37.3°C (99.1°F), heart rate 80 bpm, respiratory rate 18 breaths per minute. Examination revealed mild pharyngeal congestion and Grade I tonsillar enlargement. Lung auscultation showed coarse breath sounds bilaterally, though no wheezing or crackles were detected. Cardiac assessment was unremarkable.

Blood tests indicated a slight elevation in white blood cell count, suggesting an ongoing infection, while other markers remained within normal limits. Based on clinical presentation and preliminary lab data, acute bronchitis was suspected, and further diagnostics were recommended to confirm the underlying cause.

Diagnostic Process and Treatment Plan

To pinpoint the etiology, a Mycoplasma pneumoniae antibody test was performed—and returned positive, confirming an atypical bacterial infection commonly seen in school-aged children. A subsequent chest X-ray revealed increased bronchovascular markings but no signs of pneumonia or lung consolidation, supporting the diagnosis of non-bacterial pneumonia-type acute bronchitis.

After discussing the findings with the family, a targeted antibiotic regimen was initiated. Azithromycin dry suspension, a macrolide-class antibiotic known for its high tissue penetration and once-daily dosing, was prescribed. Its mechanism involves binding to the 50S ribosomal subunit of susceptible bacteria, effectively inhibiting protein synthesis without affecting human cells.

The dosing followed a pulsed protocol: three days of active treatment followed by four days off, then another three-day cycle—ideal for managing Mycoplasma infections while minimizing gastrointestinal side effects. Additionally, Huanglong Cough-Relief Granules, a traditional Chinese medicine formulation with anti-inflammatory and expectorant properties, was added as adjunctive therapy to soothe airway irritation and support recovery.

The parents were thoroughly educated on medication adherence, potential side effects, and warning signs requiring immediate re-evaluation. They were encouraged to maintain open communication with the healthcare team throughout the treatment period.

Follow-Up and Recovery Progress

Fourteen days after initiating therapy, the family returned for a follow-up visit. The parents reported dramatic improvement: fever subsided within 48 hours of starting azithromycin, and cough frequency decreased significantly by day seven. By the end of the two-week course, all symptoms had vanished entirely.

Repeat laboratory testing—including complete blood count and chest imaging—showed no abnormalities. The treating physician concluded that the infection had been successfully eradicated, and no further intervention was necessary. The parents expressed high satisfaction with both the treatment outcome and the clarity of medical guidance provided.

Key Recommendations for Families Managing Childhood Respiratory Infections

Parents often feel anxious when their children suffer from prolonged respiratory illness. To ensure optimal recovery and prevent complications, consider the following evidence-based advice:

1. Adhere Strictly to Prescribed Medications

Do not stop or adjust antibiotics based on perceived symptom improvement. Completing the full course ensures the pathogen is fully eliminated and reduces the risk of developing resistant strains.

2. Support Immune Function Through Nutrition

Focus on a balanced diet rich in vitamins and protein. Incorporate fresh fruits, leafy vegetables, dairy products, eggs, and lean meats to fuel the body's natural healing processes during illness.

3. Encourage Moderate Physical Activity

Once fever-free and feeling better, light aerobic activities like walking or gentle play can boost circulation and immune resilience—just avoid overexertion.

4. Monitor for Warning Signs

Seek prompt medical attention if new symptoms arise, such as difficulty breathing, chest pain, persistent high fever, or lethargy.

Clinical Insights: Understanding Acute Bronchitis in Children

Acute bronchitis is an inflammation of the trachea and bronchial tubes, typically triggered by viral or bacterial infections, environmental irritants, or allergic reactions. While often self-limiting, cases involving pathogens like Mycoplasma pneumoniae may require specific antimicrobial therapy.

Symptoms include persistent cough (sometimes lasting several weeks), mucus production, chest tightness, shortness of breath, and occasionally low-grade fever. Unlike common colds, these symptoms tend to linger and progressively worsen without proper management.

This case highlights the importance of accurate diagnosis through lab testing and imaging, especially when initial treatments fail. Early identification of Mycoplasma infection allowed for timely use of azithromycin—an effective, well-tolerated option for pediatric patients. With appropriate care, most children recover fully without long-term consequences.

In conclusion, recognizing the signs of respiratory infection, seeking professional evaluation early, and following a structured treatment plan are critical steps toward ensuring a swift and safe recovery for young patients.
