Multiple sclerosis, or MS, is aninflammatory, demyelinatingdisease of the central nervoussystem.
Continual deposition of scleroticplaques leads to progressivephysical disability. Etiologicagents, exacerbating or remittingagents, and curative modalitieshave not been firmly established.

In 1868, French neurologistJean-Martin Charcot becamethe first person to describemultiple sclerosis as a distinct
disease, calling it sclerose en plaques .Charcot's triad of multiplesclerosis refers to nystagmus,intention tremor, and telegraphicspeech. He was one of theforemost neurologists of his day,and many other medical termsalso bear his name: Charcot's
joint, Charcot-Marie- Toothdisease, Charcot-Leydencrystals, and others.

Multiple Sclerosis is the most common neurological disease affectingadults in Canada*Canada has one of the highest rates of Multiple Sclerosis in the world*
It is much more common among white persons living in northern
latitudes, but individuals who move to northern climates before the ageof 15 years also have an increased risk.Females are twice as likely as males to develop MS, and it mostcommonly affects adults aged 18-50.
In some MS natural-history studies, overall life expectancy has beenshown to be only 5-7 years shorter, but patients usually die from
complications associated with MS and not from the disease itself

Multiple sclerosis refers to the plaques that are deposited in theparenchyma of the brain, brain stem, optic nerves, and spinal cord
These MS lesions are perivenular infiltration of lymphocytes andmacrophages that most commonly involve the white matter

Common findings include localized weakness, focal sensorydisturbances, hyperreflexia, stiffness, ocular findings, and gait
disturbances.Secondary problems include infections, skin ulcers, andmusculoskeletal complaints.
The 10-point Kurtzke Expanded Disability Status Scale allows for accurate rating of disease sign and symptom severity.
COMMON PROBLEMS

Medications used to treat MS are classified as either disease-modifying or symptomatic managementNo currently approved medications offer any hope of cure.For acute exacerbations, methylprednisolone is given to shorten the
flare duration.For patients with relapsing MS, interferon beta (1a or 1b), natalizumab,glatiramer acetate, and mitoxantrone are FD A approved.Mitoxantrone is also approved for secondary-progressive andprogressive-relapsing MS.No approved treatments are available for primary-progressive MS.

Multiple Sclerosis is primarily a disease of women in their childbearing yearsMany women around the world diagnosed with MS are
fighting to live a normal life including becoming mothersBut« How informed are women about the diseaseinteraction with pregnancy?

94 (62.7%) of 150 women had at least one child In 36 women (24%) the diagnosis MS was known at the time of their
last pregnancyFour questions concerning MS and pregnancy were asked using
multiple-choice. Four possible answers to each question were given,one of which was correct. Of a total of 146 patients, only sevenpatients (4.8%) gave correct answers to all four questions
The level of knowledge concerning issues related to MS andpregnancy in the group of patients with the diagnosis MS at the time of their last pregnancy was significantly higher (p < 0.001, chi-square-

Scant information on the influence of MS on pregnancy and birthoutcomes in WW MS has been available
It has been generally assumed, from small studies, that the impact isminimal*
A PubMed scan using keywords ³MS and pregnancy outcomes´reveals 97 publications, compared to 554 citations using ³epilepsy andpregnancy outcomes.´
The majority of registries for MS are focused on the impact of pregnancy on disease or are specific to individual immune-modulatingdrugs in postmarketing surveillance efforts

births in this time period were 449 births given by MS mothers and851,060 control births The MS mothers had a higher rate of induction of labour, and there
was a strong trend for slower progression of second stage of labour and increased use of forceps
The MS group had lower birth weight and length of the neonates The frequency of birth defects and the neonatal mortality were not

There was a significantly lower mean birth weight in term births (adjustedfor gestation in weeks, mother's age, time period and caesarean section)in the manifest MS compared to the pre MS group (P = 0.046)
The rate of birth complications and interventions did not differ between thethree groups

The available published data confirms a significant increase in IUG R inwomen with MS.Patients with MS require more antenatal admissions
There is probably a higher risk of having a caesarean section.
Limited data suggests an increased risk of preterm birth.Because the available published data does not account for diseaseseverity and disability during pregnancy, we can not categorizepatients as ³High Risk´ or ³Low Risk´ MS patients.
The effect of concurrent use of long term medications, immune-modulators, and acute therapy of relapses during pregnancy is diluted
in the registry data.

Apart from methotrexate and cyclophosphamide, most drugs usedregularly to treat MS can safely be used by pregnant women
Intravenous steroids may be used with relative safety duringpregnancy
Maternal use of azathioprine is not associated with an increased risk of congenital malformations, though impaired foetal immunity, intrauterinegrowth retardation and prematurity are occasionally observedCyclosporin is not teratogenic, but may be associated with growthretardation and prematurity

Korn-Lubetzki and colleagues found, in a large retrospective study,that the frequency of relapses of multiple sclerosis decreased duringpregnancy, increased in the immediate post-partum period and wassimilar to the frequency observed out of pregnancy when considering
the pregnancy year (9 months of pregnancy and the first 3 monthspost-partum).

The Pregnancy in Multiple Sclerosis (PR IMS) study was the first largeprospective study of the natural history of multiple sclerosis in pregnantwomen254 women with multiple sclerosis during 269 pregnancies in 12
European countriesShowed a significant decline in the relapse rate during pregnancy,most marked in the third trimester, with a rebound increase in the first3 months post-partum. T here was no apparent acceleration of disability during the puerperium and neither breast-feeding nor epiduralanalgesia had any specific adverse effect.

During pregnancy, there is a measurable increase in the number of circulating CD4(+) IFN-gamma-producing cells
A decline in circulating CD4(+) IFN-gamma-producing cells leads topostpartum MS relapses. Our findings also suggest that the decline in
these cells may begin during late pregnancy and that lactationalamenorrhea induced by exclusive breastfeeding may be able tointerrupt this process.

The common knowledge after PR IMS and similar trials was thatbreastfeeding does not cause more relapse in women with MS.Exclusive breastfeeding and concomitant suppression of mensessignificantly reduce the risk of postpartum relapses in MS. T hese findingscall into question the benefit of foregoing breastfeeding to start MStherapies and should be confirmed in a larger prospective studies.
