我的女兒得脊椎性肌肉萎縮症?
Q:
> 您好!
>
> 我想請問貴單位:
> 我的小女兒現在7個月大,在她四個月的時候,發現她呼吸的聲音很大,且雙腳似乎比較無力,皆異於一般小孩,帶至基隆長庚醫院檢查,由於基隆長庚沒有支氣管鏡,於是建議我們帶至林口長庚兒童醫院,隔天便住進兒童醫院等待檢查。當天下午發現她有時嘴唇會發紫,於是醫院給予氧氣罩治療。由於她的呼吸一直有點急促,所以醫師不敢為她作支氣管鏡,住了兩星期僅作了一般的血液檢查、腦部超音波,其報告皆為正常,一直檢查不出原因,我們即為她辦理轉院回基隆長庚,以便就近照顧。當晚,她即因為呼吸急促轉進加護病房,在肌電圖及肌肉切片檢查下,醫師證實她為脊椎性肌肉萎縮症,不久後轉送中壢佑民醫院給予呼吸照護。

問題二:為什麼基因的檢查報告是正常的,那導致此病的真正原因為何?

問題三:難道我們現在只能耗到她走到生命盡頭?我們能為她做些什麼?

> This 5 m/o female patient is a victim of SMA type 1 confirmed by muscle

> Comments:
> NCS:
> Reduced amplitude of
R’t median CMAP.
> Absence amplitude of
Bil. ulnar peroneal tibial CMAP.
> Decreased R’t
median MNCV.
> EMG:
> Fib, PSW in R’t L4,
L5 muscle.
> Increase insertion
activity, fibrillation, positive sharp wave

> Conclusion:
> Anterion horn cell
disorder, such as SMA type I is highly

> Please correlate with
clinical condition.
> Suggest muscle biopsy.

> Muscle biopsy was performed also, and SMA type 1 has been confirmed and
> Endotracheal tube with ventilator dependent is necessary. Except for SMA

> Final diagnosis:
> 1) pneumonia and RUL collapse
> 2) SMA type 1.
> Tx:
> 1) chest care with supportive treatment
> 2) ETT tube with ventilator dependent were necessary.
> 3) Trachostomy was suggested

敬啟者:
1. 貴寶寶所患肌肉萎請縮症,確屬不治之罕見疾病。
2.
對於相關自身的疾病,最正確的診斷是肌肉切片檢查,其他檢查都是相關的佐証或
合併症的檢查。人体基因數目上萬,就所知的檢查屬正常,此疾相對基因,若無法正確
定位,當然,不易查其不正常之處,至於真正原因,目前不知道。
3.
正常肌肉的活動,由大腦發出信息,經神經傳導,每由神經、肌肉的收縮、活動。
當這些路徑有問題疾病時,都能導致肌肉的麻痺,活力減弱,而至萎縮,貴寶寶的疾病
是屬最後一關,肌肉本身的萎縮,原因不明,且是漸進式,先是微小的肌肉無力,眼皮
下重,聲音沙啞,吞嚥困難,呼吸無力,困難,行動無力‥我們能做的,盡力而為。
4. 衛生署公佈六十種罕見疾病,貴寶寶屬第5O種Spinal
Muscual Atrophy(SMA脊髓
性肌肉萎縮症)
