CARDIOVASCULAR DISEASES Flashcards
a rare but serious bacterial infection in your blood. It causes severe symptoms that get worse fast, including muscle pain, cold hands and feet, lethargy, chills, fever, a rash and more
meningococcemia
causative agent of meningococcemia
neisseria meningitidis
how many serogroups are there in the capsular polysaccharide of n. meningitidis?
13 (A, B, C, D, 2gE, H, I, K, L, W135, X, Y, Z)
which 5 n. meningitidis serogroups are most frequent and vaccine preventable?
A, B, C, W135, Y
which n. meningitidis serogroup capsule is immunologically identical to E.coli K-1?
serogroup B
which n. meningitidis OMP define the serotype?
Class 2 and 3
which n.meningitidis OMP defines subtype?
class 1
true or false: meningococci is exclusively a human pathogen
true
common habitat or meningococci
oropharynx or nasopharynx
mode of transmission of n. meningitidis
- contact
- droplets
- follows URT infection
- multi-organ disease, consumptive, coagulopathy, petechial or purpuric rash
deficiency in complement C5 to C8 predisposes to infection
meningococcemia
- initially pink maculopapular lesions
- later evolves into non-blanching petechial rah in trunk and lower extremities
acute meningococcemia
- most severe form of meningococcemia
- high fever, shock, widespread pupura, intravascular coag, thrombocytopenia, and adrenal insufficiency
- hemorrhagic destruction of the adrenal glands
waterhouse-friderichsen syndrome
diagnostic procedure for meningococcemia
- CSF profile
- gram stain
treatment for meningococcemia
- penicillin G
vaccines for meningcoccemia
- MPSV4 polysacchariade vaccine
- MCV4 conjugate vaccine
MPSV4 vs MCV4
- quadrivalent
- for elderly > 55
MPSV4
MPSV4 vs MCV4
- quadrivalent + diptheria toxin mutant
- 2-55 y/o
MCV4
abnomal, delayed, often recurrent autoimmune reaction to Group A beta hemolytic streptococcal pharyngitis involving the joints, skin, brain, serous surface, and heart
rheumatic fever
rheumatic fever attacking and reccurence often results to
rheumatic heart disease
true or false: rheumatic fever is the most common cause of acquired disease in children more than 5 y/o in the ph
true
also classified as a post-infectious connective tissue disease
rheumatic fever
prevalence rate of rheumatic fever in the PH pero 1000
0.1 to 22 per 1000
percentage of recurrence of rheumatic fever / streptococcal infection in the PH
14.6%
