What is the treatment approach for Respiratory Syncytial Virus (RSV) infection in elderly patients?

Treatment Approach for Respiratory Syncytial Virus (RSV) in Elderly Patients

Treatment for RSV in elderly patients is primarily supportive care, as there are no specific FDA-approved antiviral treatments for RSV in adults, while vaccination is now recommended as the primary preventive strategy for this high-risk population. 1

Supportive Care Management

• Supportive care remains the mainstay of RSV treatment in elderly patients, including:

  • Adequate hydration and fluid management 2, 3
  • Antipyretics for fever control 4
  • Oxygen supplementation when needed to maintain adequate oxygen saturation 4, 3
  • Close monitoring of respiratory status and prompt intervention for respiratory distress 1, 3

• For elderly patients with underlying respiratory conditions such as COPD or asthma, management of exacerbations according to standard protocols is essential 1

• Functional status assessment should be incorporated into care plans, as RSV infection can cause significant functional decline in elderly patients, particularly those with pre-existing frailty 1

Diagnostic Considerations

• Nucleic acid-based testing (RT-PCR) is recommended for diagnosis of RSV in elderly patients, particularly those at high risk for severe disease 1

• Testing is especially important in immunocompromised elderly patients, including those with:

  • Solid organ or hematopoietic stem cell transplants 1
  • Hematological malignancies or solid tumors 1
  • Chronic immunosuppressive therapy 1
  • HIV infection 1

Special Considerations for High-Risk Elderly Patients

• For severely immunocompromised elderly patients (particularly transplant recipients), off-label use of ribavirin may be considered based on observational data 1, 3

• For immunocompromised patients, early bronchoscopy may be valuable for diagnosis 3

• Intravenous immunoglobulin has been used in combination with ribavirin in immunocompromised patients with severe disease, though evidence is limited 2, 3

• Standard infection control practices are crucial, especially in nursing homes and long-term care facilities:

  • Hand hygiene 2, 3
  • Use of gowns and gloves 2, 3
  • Isolation precautions for infected patients 1

Prevention Through Vaccination

• Two RSV vaccines are now available and recommended for elderly patients 1:

  • RSVPreF3 (recombinant RSV pre-fusion F protein adjuvanted with AS01E) for adults ≥60 years and adults 50-59 years at increased risk 1
  • RSVpreF (recombinant bivalent RSV-A and RSV-B pre-fusion F protein) for adults ≥60 years 1

• Vaccination is particularly important for:

  • All adults aged ≥75 years regardless of comorbidities 5
  • Adults aged 60-74 years with risk factors (COPD, asthma, heart failure, chronic kidney disease, diabetes, chronic liver disease, immunocompromise) 5
  • Residents of nursing homes or long-term care facilities 5

• Vaccination should preferably be administered between September and November, before or early in the RSV season 5

• A single dose is recommended, and can be co-administered with seasonal influenza vaccine at different injection sites 5

Clinical Pitfalls and Caveats

• RSV infection in elderly patients is often underdiagnosed due to:

  • Symptoms that mimic influenza or other respiratory infections 2, 3
  • Lower viral titers in nasal secretions making detection more difficult 2, 3
  • Limited availability of sensitive diagnostic tests in many settings 2

• The mortality rate from RSV in hospitalized elderly patients can be significant (4.6% in those aged 60-74 years and 6.1% in those ≥75 years) 1

• Elderly patients with dementia have higher mid- to long-term mortality following RSV infection (aHR = 1.86) 1

• Functional decline following RSV infection can be prolonged, particularly in frail elderly patients from skilled nursing facilities 1
