How is OPSI diagnosed?
OPSI is a medical emergency that requires prompt diagnosis (with blood cultures and sensitivity, blood glucose levels, renal function tests, and electrolyte levels) and management with fluid resuscitation along with immediate administration of empirical antimicrobials.
What is the most common organism associated with OPSI?
The most important pathogen is Streptococcus pneumoniae, but Haemophilus influenza and Neisseria meningitidis are also significant. These are all encapsulated organisms that thrive in the absence of the opsonization and phagocytosis provided by splenic macrophages.
What causes OPSI?
The mechanism that connects splenectomy to WFS is unknown but the possible causes of OPSI include loss of splenic phagocytic function, decreasing serum immunoglobulin levels, suppression of lymphocyte sensitivity, or a change in the opsonin system[27,28].
How is OPSI treated?
Treatment of OPSI is generally aggressive with intravenous fluids, antibiotics, vasopressors, steroids, heparin, packed red blood cells, platelets, cryoprecipitates, and fresh frozen plasma [15]. Due to its fulminant and fatal nature, prevention is of utmost importance in immunocompromised asplenic patients [5].
What does OPSI mean?

How long does thrombocytosis last after splenectomy?
Reactive thrombocytosis is a predictable finding after splenectomy, with the platelet count peaking at 1 to 3 weeks and returning to normal levels in weeks, months, and, rarely, years (3).
What are the long term effects of a splenectomy?
A recent study from a large cohort of American veterans showed an increased risk of death due to septicemia, pulmonary embolism, coronary artery disease and cancer more than 10 years after splenectomy.
How does the spleen clear encapsulated bacteria?
Normally, encapsulated pathogens are opsonized with antibodies and then phagocytosed by specialized macrophages in the spleen. Individuals with asplenia lack these specialized macrophages, so pathogens are able to spread and cause sepsis.
How do you fix thrombocytosis?
Your doctor might prescribe platelet-lowering drugs primarily in the form of hydroxyurea (Droxia, Hydrea) or interferon alfa (Intron A). Platelets can be removed from your blood by a procedure that’s similar to dialysis.
How long do people live after a splenectomy?
Survival. When considering all cases, the median survival was 80 months. Following emergency splenectomy, the median survival was 72 months compared with 89 months following elective surgery (p=0.381) (Table 1).
Which is the most common early complication following splenectomy?
Infections, particularly pulmonary and abdominal sepsis, constitute the majority of the complications. The mortality rate from postoperative sepsis is substantial. Atelectasis, pancreatitis/fistula, pulmonary embolism and bleeding at the operative site are also relatively common occurrences following splenic removal.
What is OPSI in spleen?
An overwhelming post-splenectomy infection (OPSI) is a rare but rapidly fatal infection occurring in individuals following removal (or permanent dysfunction) of the spleen.
What is the meaning of OPSI?
OPSI may stand for: Overwhelming post-splenectomy infection, rapidly fatal septicaemia in a patient who has undergone splenectomy (removal of the spleen).
Which cancers cause high platelet count?
A recent increase in the platelet count was associated with risk of colon cancer (OR, 5.52; 95% CI, 5.21-5.86), lung cancer (OR, 4.77; 95% CI, 4.51-5.04), ovarian cancer (OR, 7.23; 95% CI, 6.12-8.53), and stomach cancer (OR, 5.51; 95% CI, 4.82-6.29) (Figure 3 and eTable 7 in the Supplement).
What are the symptoms of rare pancreatic cancer?

Insulinomas (excess insulin ): sweating, anxiety, lightheadedness, and fainting from low blood sugar Glucagonomas (excess glucagon): diarrhea, excessive thirst or urination, weight loss Gastrinomas (excess gastrin ): abdominal pain, stomach ulcers that can bleed, reflux,…
What are the symptoms of pancreatic insufficiency?
Because of the location of the pancreas in the body, symptoms include: Jaundice. Abdominal pain. Back pain. Bloating. Nausea. Vomiting.
What are the symptoms of Stage 7 pancreatic cancer?

What are the symptoms of pancreatic nets spreading?
Symptoms caused by the cancer spreading. When pancreatic NETs spread, most often they go to the liver. This can enlarge the liver, which can cause pain and loss of appetite. It can also affect liver function, sometimes leading to jaundice (yellowing of the skin and eyes) and abnormal blood tests.
