MS treatment Flashcards
(30 cards)
relpase of ms ttt
methypredinsalone
IV ; 1gm /day ; 3 - 5 days
po ; 50 mg/d for 5 dyas
dmd aim
- reduce relapse frequency and severity
- prossive disaability to be avoided
3.reduce disability from relapse
first line treatment of dmd
interferone or galitramer acteate
action of interferone
*Reduces leukocyte proliferation
*Reduces antigen presentation
*Modulates cytokine production
*Reduces T cell migration
names of drugs of interferone
Avonex Intramuscular β-interferon-1a 30ug once/week
› Rebif Subcutaneous β-interferon-1a 22 or 44ug 3 times/week
› Betaferon Subcutaneous β-beta interferon-1b 250ug alternate days
advantages of beta interferone
Modulates immune system
* Reduces relapse rate by 30%
* Reduces severe relapses by 50%
* Slows disability and cognitive impairment in relapsing remitting MS
by ~ 20%
* Reduces new MRI lesions by 50-70%
* No effect on primary orsecondary progression
* Long term effects (beyond 2-3 years) uncertain
side effect beta interferone
Flu-like symptoms, muscle aches, headache
* Injection site reactions (subcutaneous β- IFNs)
* Decreased white cell count, liver dysfunction
* Hair loss
* Depression
* Thyroid diseases
interferone must be followed up by
cbc and liverfunction because ; decrease wbcs and liver cell dysfunction
glatriamer acetate [ copaxone ]
Mechanism of action: Shift the population from TH1 cells to Th2 regulatory cells to suppress
the immune response.
* Cause in situ bystander suppression of auto-aggressive TH1 T cells
advantages of glatriamer
Regulates immune system
* Reduces relapse rate by 30%
* No effect on primary progressive MS
* No trials in secondary progressiveM
side effect of capoxane
injection site reaction
hypersenstivity [ rare]
allergic reactions ; chest tightness , shortness of breath , palpitations
loss of fat under site lipoatrophy at injection site
NHS “risk sharing scheme” guidelines for ß interferon & Galtiramer
actetate in RR M
- Two relapses in Two year
- Able to walk with or without assistance
NHS “risk sharing scheme” guidelines for ß interferon (1-b) in RR MS
- Two relapses in two years
- Able to walk at least 10 m with or without assistance
- Minimal increase in disability due to slow progression over 2 years
natluzimab [ biiological ]
humanized antibody
natalizumab [tysabri]
given once per month
adavntages of natalizumab
reduce relapse rate by 68 percent
80-90 percent reduce new mri lesion
reduce rate of disability progression by 42 percent
side effect of natalizumab
Infections
* Infusion (allergic) and hypersensitivity
reactions
* Urticaria
* Headache
* Dizziness
* Vomiting, nausea
* Arthralgia
* Progressive multifocal
leukoencephalopathy (PML) (1:500)a
natalizumab) increases the risk of PML, an opportunistic viral infection of the brain that usually leads to death or severe disability. Risk factors for the development of PML include the presence of anti-JCV antibodies, duration of therapy, and prior use of immunosuppressants.
serious side effect
indications fo use natalizumab
1.Natalizumab is recommended by NICE for rapidly
evolving severe RRMS (first line treatment)
* 2 or mores disabling attacks per year AND
* One or more enhancing lesions or significant
increase in T2 load compared with previous MRi
2.Natalizumab is also recommended by
NICE for RR MS with high disease activity
despite ß interferon (second line
treatment)
* 1 relapse in previous year while on
therapy AND
* At least 9 T2 lesions or one enhancing
lesion
Teriflunomide (Aubagio)
Mechanism of action: Decrease in lymphocytic profileration.
* Effectiveness: Relapse reduction rate of approx. 30%
* Indication: RRMS
side effect of aubigo
: slight thrombocyte and leukocyte reduction, gastrointestinal
symptoms, hepatic impairment, reversible hair thinning, peripheral neuropathies
and acute uric acid nephropathy
Dimethyl fumarate (Tecfidera):
Mechanism of action: amplification of Th2 responses
Has antioxidative and immunoregulatory effects
Modulation of the differentiation of antigen presenting cells.
* Effectiveness: reduction of relapse rate by approx. 50% vs. placebo
* Indication: RRMS
side effects of tecfidera
GIT upset
lymphopenia
pml
- Fingolimod (Gilenya
Was the first oral FDA approved drug for relapsing form of MS
