Insights

Vaccinations against encapsulated bacteria, including pneumococcal, meningococcal, and Haemophilus influenzae (Hib), are crucial for preventing post-splenectomy sepsis. Optimal timing for these essential immunizations is at least 14 days before surgery or after the 14th postoperative day.

Area of Science:

  • Infectious Disease
  • Immunology
  • Surgical Outcomes

Background:

  • Post-splenectomy sepsis is a serious risk following spleen removal.
  • Encapsulated bacterial pathogens are a primary cause of post-splenectomy infections.

Purpose of the Study:

  • To review the evidence for immunizations in preventing post-splenectomy sepsis.
  • To establish recommended vaccination protocols for asplenic patients.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) for pneumococcal vaccine efficacy.
  • Systematic review of clinical trials for meningococcal and Haemophilus influenzae (Hib) vaccine efficacy.

Main Results:

  • Immunization significantly reduces the incidence of post-splenectomy sepsis.
  • Pneumococcal, meningococcal, and Hib vaccines are indicated for patients undergoing splenectomy.

Conclusions:

  • Vaccination is a key strategy to mitigate infection risk in asplenic individuals.
  • Recommended vaccination timing is at least 14 days pre-operatively or post-14th day post-operatively.

Overview
Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Vaccines01:21

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...
Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
