Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like infection. It can cause stroke, hearing loss, and brain damage. It can also harm other organs.

Specific Coding for Listerial meningitis and meningoencephalitis

Non-specific codes like A32.1 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for listerial meningitis and meningoencephalitis:

Information for Patients

Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever.

Is meningitis a localized infection?

So yes to your question, in that meningitis is originally localized to the CNS and then becomes systemic sepsis.

Is meningitis a PDX?

According to the logic under DRG tips pg 49 of the 2014 CDI Pocket Guide, Alt DRG 94 Meningitis as an interrelated PDX with sepsis. Tips, "Most cases of meningitis are caused by bacteria or viruses that enter the bloodstream via the upper respiratory tract and then infect the meninges of the brain. Meningitis is not typically a localized infection that progresses to sepsis. Bacteremia or septicemia, when it occurs, usually precedes the meningitis. Because there is no underlying/localized infection, the two may be considered interrelated and either sequenced as PDX, although meningitis is likely to be the focus of the admission".

What is the most common age for Listeria monocytogenes meningitis?

The highest age-specific rates for Listeria monocytogenes meningitis are amongst neonates and adults over 60 . Neonates acquire early-onset infection in utero, or late-onset within a few weeks of birth, when infection is more likely to lead to meningitis. In adults, pregnancy is the commonest risk factor. In other adults, risk factors include advanced age, immunosuppression, malignancy, renal failure, diabetes, alcohol abuse, HIV infection, organ transplantation and administration of corticosteroids or cytotoxic chemotherapy. Since the organism is intracellular, defects of cell-mediated immunity, but not complement or immunoglobulin deficiency, are risk factors for infection.

How does Listeria monocytogenes enter the brain?

We will now describe the mechanisms of brain invasion used by a bacterium that causes meningitis, Listeria monocytogenes.94 This Gram-positive bacterium is a food-borne pathogen that can invade the central nervous systems by three distinct mechanisms 95: (1) direct infection of endothelial cells, (2) passage of infected monocytes through the blood–brain barrier, and (3) infection of peripheral neurons and retrograde transport to the brain. In this respect, and although L. monocytogenes is far from a brain-exclusive pathogen, this bacterium is particularly efficient at invading brain tissues. Correspondingly, central nervous system infections are present in about 50% of infected patients. 96 Moreover, L. monocytogenes is one of the most common causes of bacterial meningitis in western countries. 97–99 As a food contaminant, L. monocytogenes enters the body through the gastrointestinal mucosa. 100 It has thus developed adaptive strategies to resist to the low pH of the stomach, and to the detergent activity of bile salts in the upper small intestine. 101 L. monocytogenes penetrates the intestinal mucosa directly via enterocytes, or indirectly via invasion of Peyer’s patches. 102 Following this passage through the gastrointestinal barrier, the bacterium spreads via the lymph and the blood to distant tissues. In the peripheral blood, L. monocytogenes is found in a subpopulation of monocytes that sustain a systemic infection status. 103 These infected monocytes can adhere to the wall of brain capillaries and migrate into brain tissues by diapedesis through the endothelium. 104 This Trojan horse mechanism mediated by infected monocytes is quite similar to the one described for HIV ( Fig. 12.6 ). Alternatively, free L. monocytogenes can infect brain endothelial cells and replicate in these cells. 105 Thus, direct infection of endothelial cells is a second route of entry of this bacterium from the blood stream to the brain. The third route of brain invasion by L. monocytogenes involves peripheral neurons and retrograde axonal transport, a mechanism also used by rabies virus ( Fig. 12.3 ). This neural route of infection has been suspected for several cases of brain encephalitis associated with L. monocytogenes.106 Correspondingly, inflammatory lesions associated with L. monocytogenes infection have been observed in cranial nerves V, VII, IX, and XII that innervate the oropharynx. 107

What is the pathogenicity of L. monocytogenes?

The pathogenicity of L. monocytogenes is mediated by a pore-forming hemolysin toxin, listeriolysin O. It is interesting to note that this toxin is used by the bacterium to escape the intracellular vacuoles of infected monocytes during the course of cell-to-cell transmission. 108 Listeriolysin O belongs to the family of cholesterol-dependent cytolysins that contains more than 20 pore-forming toxins produced by various bacteria including Bacillus anthracis (anthrolysin), Clostridium perfringens (perfringolysin), and Streptococcus pneumoniae (pneumolysin). 109 All these toxins are secreted by bacteria as soluble monomers but, following binding to cholesterol in host cell membranes, oligomerize into large pores (up to 35 nm in diameter). The choice of cholesterol among other lipids in the membrane of host cells is important, because it assures that the toxin cannot be harmful for the bacterium that produces it, given that bacterial membranes lack cholesterol. 109 Mutational studies have indicated that cholesterol is recognized by two consecutive amino acids, Thr-515 and Leu-516, 110,111 which form a “sensor” at the tip of a short loop joining two β-strands (505–514 and 517–525) in the C-terminal domain of listeriolysin O 112 ( Fig. 12.8 ).

What is the C-terminal region of listeriolysin?

The C-terminal region of listeriolysin O (PDB entry # 4CDB) contains a series of β-strands linked by short loops. One of these loops corresponds to a conserved undecapeptide involved in membrane insertion. A pair of residues (Thr-516/Leu-516) has been identified as critical for cholesterol binding by mutational studies. We find a cholesterol-binding domain (CBD, shaded in yellow in the model on the left) in the structure of listeriolysin O. Molecular dynamics simulations show that this domain displays a high affinity for cholesterol (model in the middle panel). The amino acid residues of the CBD involved in cholesterol binding are shown on the right panel.

What is the function of L monocytogenes?

L. monocytogenes expresses surface proteins termed internalins that promote its entry into epithelial cells and hepatocytes. After phagocytosis it becomes enclosed in a subcellular organelle, a phagolysosome, the low pH of which activates listeriolysin O, an exotoxin that leads to rapid lysis of the organelle membrane and release of the organism. Once in the cytoplasm, the organism proliferates, and becomes encased in host cell actin filaments that enable the organism to form a filopod, which may be ingested by adjacent cells, so allowing transmission of the disease without bacterial exposure to the extracellular environment. The organism crosses the meninges and blood–brain barrier by endothelial cell or macrophage phagocytosis, and the use of the host cell contractile system to migrate to and grow within the brain [94].

Is Listeria monocytogenes meningitis uncommon?

Listeria monocytogenes meningitis is less uncommon than previously thought. When it occurs in the newborn, it appears to result from maternal genital tract infection. It is also encountered in adults and is especially associated with lymphoreticular disease, immune suppression (as in transplant patients), pregnancy, ...

Does Listeria enter the brain?

Listeria may invade the brainstem and the cerebral cortex; this does not occur in other forms of bacterial meningitis. There are differences in the relative importance of host factors during the immune response to meningeal versus systemic listeriosis.
