A bacterial test in children with sinusitis can reduce the use of antibiotics

In a recent study published in JAMA, researchers from the University of Pittsburgh and UPMC found that a simple nasal swab test for three types of bacteria can help determine whether antibiotics are likely to be effective in children with suspected sinusitis. The condition, characterized by inflammation or swelling of the sinuses, can cause congestion, discomfort, and difficulty breathing. Currently, doctors often prescribe antibiotics to treat sinusitis, but this approach may not be necessary as the condition can also be caused by viruses.

Lead author Dr. Nader Shaikh, a pediatrician at UPMC Children’s Hospital of Pittsburgh and professor of pediatrics and clinical and translational science at Pitt, explained that only about half of the five million children in the U.S. prescribed antibiotics for sinusitis experience symptom improvement with this treatment. By identifying which children are likely to benefit from antibiotics, unnecessary antibiotic use could be significantly reduced.

The study aimed to develop a better diagnostic tool for bacterial sinusitis. Approximately 500 children with sinusitis symptoms were enrolled from six centers across the U.S. and randomly assigned to receive either antibiotics or a placebo. Nasal swabs were taken from each child and tested for the three main types of bacteria associated with sinusitis. The results showed that children who tested positive for the bacteria had better symptom resolution with antibiotic treatment compared to those without bacteria, suggesting that bacterial testing could effectively identify children who would benefit from antibiotics.

Dr. Shaikh emphasized the importance of avoiding unnecessary antibiotic use, as these medications can have side effects and contribute to antibiotic resistance. The belief that yellow or green nasal discharge indicates a bacterial infection was also debunked in the study. Color should not be used as a guide for medical decisions regarding sinusitis treatment.

The researchers are now exploring how to implement nasal testing in clinics. Current bacterial culture-based tests are not easily accessible for most family doctors and may take several days to yield results. To address this, commercially available molecular testing could be a practical option, providing faster results. Additionally, the development of rapid antigen tests similar to COVID-19 at-home testing kits is being considered. Further investigation into other biomarkers in nasal discharge that may indicate bacterial presence and be easier to test for is also planned.

Standards of Treatment of Bacterial Sinusitis in Children

Bacterial sinusitis is a common condition among children, characterized by inflammation or swelling of the sinuses. When bacterial infection is the underlying cause, appropriate treatment becomes essential to alleviate symptoms and prevent potential complications. The standards of treatment for bacterial sinusitis in children are based on evidence-based guidelines established by medical experts and organizations.

Proper diagnosis is crucial to distinguish bacterial sinusitis from viral infections or other conditions. Physicians typically consider the duration of symptoms, such as persistent nasal congestion, runny nose, and facial discomfort, lasting more than 10 days, as an indication of possible bacterial sinusitis. Additional clinical factors and history may also be taken into account. Diagnostic tools may include physical examinations, medical history assessment, and, in some cases, imaging studies.

When bacterial sinusitis is diagnosed, appropriate antibiotics are prescribed to target the specific bacteria causing the infection. Commonly used antibiotics for pediatric sinusitis include amoxicillin, amoxicillin-clavulanate, and cefdinir. The choice of antibiotic depends on the child’s age, the severity of symptoms, and any known allergies to medications.

The duration of antibiotic treatment for bacterial sinusitis in children typically ranges from 10 to 14 days. It is essential for parents and caregivers to ensure that the entire course of antibiotics is completed, even if the child starts feeling better before finishing the medication. Prematurely stopping antibiotics may lead to incomplete eradication of the bacteria, potentially contributing to antibiotic resistance.

Regular follow-up visits with the healthcare provider are important to monitor the child’s progress and assess the effectiveness of the chosen treatment. If the symptoms do not improve or worsen during or after the antibiotic treatment, further evaluation may be required to rule out complications or alternative diagnoses.

In addition to antibiotics, supportive care plays a significant role in managing bacterial sinusitis in children. Adequate hydration, rest, and over-the-counter medications for symptom relief, such as nasal decongestants and pain relievers (age-appropriate and approved by the healthcare provider), can be beneficial in easing discomfort.

Healthcare providers strive to limit antibiotic overuse and avoid prescribing antibiotics for viral infections, as they are ineffective against viruses and may contribute to antibiotic resistance. By carefully evaluating the symptoms and confirming bacterial involvement through diagnostic tests, antibiotics can be more appropriately prescribed only when necessary.

It is important to note that treatment approaches may vary depending on individual patient factors and local antibiotic resistance patterns. Parents and caregivers should always consult a qualified healthcare professional for an accurate diagnosis and appropriate management of bacterial sinusitis in children. Adherence to established standards of treatment helps ensure optimal outcomes and minimizes the risk of complications while preserving the efficacy of antibiotics for future use.
