Elixhauser comorbidity method in predicting death of Spanish inpatients with asplenia and pneumococcal pneumonia. Pneumococcal pneumonia (PP) is a serious infection caused by Streptococcus pneumoniae (pneumococcus), with a wide spectrum of clinical manifestations. The aim of this study was to analyze the comorbidity factors that influenced the mortality in patients with asplenia according to PP . Discharge reports from the Spanish Minimum Basic Data Set (MBDS) was used to retrospectively analyze patients with asplenia and PP, from 1997 to 2021. Elixhauser Comorbidity Index (ECI) was calculated to predict in-hospital mortality (IHM). 97,922 patients with asplenia were included and 381 cases of PP were identified. The average age for men was 63.87 years and for women 65.99 years. In all years, ECI
Effects of a health psychology-based intervention for patients with asplenia on psychological determinants of preventive behaviour: A propensity score analysis. Patients with asplenia have an increased lifelong risk of severe infections especially post splenectomy sepsis with hospital mortality rates of 30-50%. Adherence to existing guidelines for preventive measures is low. Objective of the study is the evaluation of a novel intervention to increase health psychological outcomes in patients with asplenia resulting in better adherence to preventive measures. The intervention was evaluated by conducting a prospective, two-armed historical control group design via propensity score analysis. Focus are health-psychological outcomes: self-efficacy, intention, risk perception, behaviour
Spleen Australia guidelines for the prevention of sepsis in patients with asplenia and hyposplenism in Australia and New Zealand People with asplenia/hyposplenism are at increased risk of fulminant sepsis, which carries a high mortality rate. A range of preventive measures is recommended although there is ongoing evidence that knowledge of and adherence to these strategies is poor. There have been significant changes in recommended vaccinations since the previously published recommendations in 2008. We provide current recommendations to help Australian and New Zealand clinicians in the prevention of sepsis in patients with asplenia and hyposplenia. The guideline includes Australian epidemiological data, preferred diagnostic techniques and recommendations for optimal antimicrobial
Risk of invasive pneumococcal disease in patients with asplenia/hyposplenism: A nationwide population-based study in Korea, 2009-2018. We aimed to determine the incidence and relative risk (RR) of invasive pneumococcal disease (IPD) in patients with asplenia/hyposplenism, using a nationwide population-based database. From 2009 to 2018, all claimed cases of newly diagnosed asplenia/hyposplenism in the National Health Insurance Service in South Korea were included. The incidence and RR of IPD in asplenia/hyposplenism patients were investigated using the Korean Center for Disease Control criteria. Fifty-seven IPD cases were identified among 21,376 patients with 82,748 person-years of exposure. The cumulative 8-year IPD incidence was 0.5%; 45.6% of the infections occurred within two years after
Prevention of post-splenectomy sepsis in patients with asplenia - a study protocol of a controlled trial. Patients with asplenia have a significantly increased lifelong risk of severe invasive infections, particular post-splenectomy sepsis (PSS). Clear preventive measures have been described in the literature, but previous studies found poor implementation of prevention recommendations. Aim outcomes include, amongst others, patient self-efficacy and action-planning, asplenia-specific health literacy, general self-management and asplenia-specific self-management. In a process-evaluating part of the study interview-data on patients' and physicians' evaluation of the intervention will be gathered. This trial will provide evidence about the effectiveness of the novel prevention intervention
Sickle cell disease and malaria: decreased exposure and asplenia can modulate the risk from Plasmodium falciparum. Patients with sickle cell disease (SCD), an inherited haemoglobinopathy, have increased risk of malaria, at least in part due to impaired splenic function. Infection with Plasmodium falciparum in SCD patients can trigger painful vaso-occlusive crisis, increase the severity
Case report of congenital asplenia presenting with Haemophilus influenzae type a (Hia) sepsis: an emerging pediatric infection in Minnesota. In the pre-vaccine era, invasive disease with Haemophilus influenzae, type b (Hib) commonly presented with osteoarticular involvement. Haemophilus influenzae, type a (Hia) sepsis is a rare but emerging problem in recent years. Here, we report a case of sepsis with concomitant osteoarthritis due to Hia that was the presenting infectious disease manifestation of isolated asplenia in a young child. This unique observation adds to our understanding of sepsis and asplenia in children. A five-year-old girl developed acute Hia bacteremia and sepsis. The patient developed arthritis shortly after onset of septic shock. Arthrocentesis was culture-negative
Venous Thromboembolism in Special Populations: Preexisting Cardiopulmonary Disease, Cirrhosis, End-Stage Renal Disease, and Asplenia. Venous thromboembolism (VTE) is a common cause of morbidity and mortality. Presence of preexisting conditions, such as cardiopulmonary diseases, cirrhosis, renal dysfunction, and asplenia, commonly occurs in VTE patients. Moreover, these conditions often are risk factors for developing VTE. These preexisting conditions make VTE diagnosis and treatment challenging and worsen outcomes. Current guidelines do not include detailed features in the diagnosis and management of patients with preexisting conditions. This review discusses presence of VTE in patients with preexisting cardiopulmonary diseases, cirrhosis, renal dysfunction, and asplenia.
A registry for patients with asplenia/hyposplenism reduces the risk of infections with encapsulated organisms. Overwhelming post-splenectomy infection (OPSI) is a serious complication of asplenia. Clinical guidelines recommend numerous measures to reduce the risk of OPSI, but awareness and adherence to preventative measures are generally poor. We aimed to determine whether a registry Australia prevents 5-6 invasive infections with encapsulated organisms annually among registrants. Systematic, long-term approaches to post-splenectomy care can significantly reduce the risk of infection with encapsulated organisms among individuals with asplenia/hyposplenism.
Sporadic isolated congenital asplenia with fulminant pneumococcal meningitis: a case report and updated literature review. Isolated congenital asplenia (ICA) is a rare and life-threatening condition that predisposes patients to severe bacterial infections. Most of the reported cases are familial and the mode of inheritance is usually autosomal dominant. Here, we report a case of sporadic isolated asplenia and review the literature while focusing on sporadic cases. We report the case of an 11-month-old female infant who developed fulminant pneumococcal meningitis. The pneumococcal vaccine-unimmunized patient was hospitalized with fever, irritability, and purpura, and was diagnosed as having meningitis, septic shock, and disseminated intravascular coagulation. Streptococcus pneumoniae
A Rare Association of Congenital Asplenia with Jejunal Arteriovenous Malformation BACKGROUND Isolated congenital asplenia is a poorly understood and rare form of primary immunodeficiency, often associated with life-threatening infections. CASE REPORT We encountered a unique case of a 22-year-old asplenic male who presented with severe iron-deficiency anemia secondary to occult gastrointestinal bleeding since age 15. Our extensive work-up confirmed jejunal arteriovenous malformations as the source of the bleed. Six months after the treatment, the patient has reported no further episodes of gastrointestinal bleeding and his hemoglobin has remained stable. CONCLUSIONS A comprehensive literature review confirmed that this is the first reported case of adult congenital asplenia associated
Incidentally detected asplenia in a healthy 64-year-old female live kidney donor Heterotaxia syndromes are rare birth defects which can result in developmental malformations. A 64-year-old woman presented to the hospital for preoperative screening for kidney donation; during which she was found to have no gallbladder and no spleen, without any signs of surgical removal. This could be a new

Critical Illness in Patients with Asplenia. The critically ill, asplenic patient presents a variety of management challenges. Historically, the focus of the care of the asplenic population has been the prevention and management of infection, including the often-fatal overwhelming postsplenectomy infection with encapsulated organisms such as Streptococcus pneumoniae. Recently, however, there has
Asplenia Syndrome in a Neonate: A Case Report Asplenia syndrome is a syndrome of right isomerism or attempted bilateral right sidedness. It includes congenital asplenia in association with complex congenital cyanotic heart disease and situs anomalies of the other thoracoabdominal organs. Herein we report a case of asplenia syndrome so as to highlight and refocus attention on the possibility
Asplenia and fever A 45-year-old-man presented with the abrupt onset of a fever over 30 years after surgical splenectomy. He presented with symptoms and findings that seemed consistent with influenza. He rapidly developed fulminant meningitis that resulted in his death.
Meningococcal B Vaccine in Patients With Asplenia Patients without a spleen (asplenia) experience an increased risk for septicaemia from encapsulated bacteria, which is associated with a high mortality rate. Meningococcal bacteria can cause such infections and serogroup B is the dominant meningococcal subtype in Europe. Therefore, vaccination for risk populations like patients without a spleen a total of four study visits. A two dose schedule of BEXSERO® will be applied intramuscularly with a one month interval between doses. Seropositivity will be assessed at baseline during the first visit, one month and six months after the second vaccination. Basic demographic data (gender, age) and medical data (type of asplenia, time of splenectomy, underlying diseases, concurrent medical conditions
