Pneumococcal Vaccination para sa Pasyenteng may PTB

Para sa isang lalaking pasyente na may Pulmonary Tuberculosis (PTB) at walang history ng pneumococcal vaccination, dapat bigyan ng PCV (PCV20 o PCV15) muna, hindi PPSV23 lang. 1, 2

Rekomendasyon ng Bakuna

Bigyan ng PCV muna, hindi PPSV23 lang. Ang tamang sequence ay:

Option 1 (Pinakamainam): PCV20 Alone

  • Magbigay ng isang dose lang ng PCV20 3, 1
  • Tapos na ang series - hindi na kailangan ng PPSV23 pagkatapos 3, 1
  • Ito ang pinakasimple at pinaka-recommended na approach 2

Option 2: PCV15 + PPSV23 Sequential

  • Magbigay ng PCV15 muna 3, 1
  • Sundan ng PPSV23 pagkalipas ng ≥1 taon 3, 1, 2
  • Ang PTB ay chronic lung disease, kaya 1-year interval ang standard (hindi 8 weeks) 3, 1

Bakit PCV Muna, Hindi PPSV23?

  • Ang PCV ay dapat laging unang ibigay bago ang PPSV23 1, 4
  • Kung PPSV23 ang unang ibibigay, bumababa ang immune response sa susunod na PCV - ito ay tinatawag na "immunologic hyporesponsiveness" 4, 5
  • Ang PCV ay mas mataas ang kalidad ng immune response dahil T-cell-dependent 5
  • Ang PPSV23 pagkatapos ng PCV ay nagbibigay ng mas mataas na antibody levels kaysa PPSV23 alone 6, 5

Timing ng Vaccination

  • Maghintay na gumaling muna ang acute PTB symptoms bago magbakuna 4
  • Kapag clinically stable na ang pasyente at hindi na acutely ill, pwede na magbakuna 4
  • Walang specific waiting period pagkatapos ng PTB diagnosis - ang importante ay clinical recovery 4

Mga Dapat Tandaan (Common Pitfalls)

  • Huwag magbigay ng PPSV23 bago ang PCV - ito ay mali at makakababa ng vaccine effectiveness 4, 5
  • Huwag i-delay ang vaccination nang sobra - kapag stable na ang pasyente, magbakuna na para maprotektahan laban sa pneumococcal pneumonia 4
  • Huwag magbigay ng PCV at PPSV23 sa same day - dapat sequential with proper interval 2
  • Kung PCV20 ang ginamit, tapos na - hindi na kailangan ng additional pneumococcal vaccines 3, 1

Rationale para sa PTB Patients

  • Ang PTB ay chronic lung disease, kaya ang pasyente ay high-risk para sa pneumococcal disease 3, 1
  • Ang chronic lung disease (kasama ang PTB) ay indication para sa pneumococcal vaccination 3, 1
  • Ang 1-year interval (hindi 8 weeks) ang ginagamit dahil ang PTB ay chronic medical condition, hindi immunocompromising condition 3, 1
  • Ang mas mahabang 1-year interval ay nagbibigay ng mas mataas na booster effect kaysa 0.5-year interval 6

Summary ng Sequence

Pinakamainam na approach:

  1. Maghintay na gumaling ang acute PTB symptoms 4
  2. Magbigay ng PCV20 (single dose) 3, 1
  3. Tapos na - walang kailangan pang additional doses 3, 1

Alternative approach:

  1. Maghintay na gumaling ang acute PTB symptoms 4
  2. Magbigay ng PCV15 3, 1
  3. Pagkalipas ng ≥1 taon, magbigay ng PPSV23 3, 1, 2
