Olina cystine ezimba munda mu butoffaali bw’omubiri gwo? Kino kiyitibwa obulwadde bwa cystinosis!

Teebereza, kiki ekyandibaddewo singa amino asidi eyitibwa `(cystine)` (cysteine) etandika okukuŋŋaanyizibwa munda mu butoffaali obutonotono mu mubiri gwaffe? Eyo y’embeera eyitibwa `(Cystinosis). Buno bulwadde bwa buzaale obutatera kulabika nga tebutera kulabibwa, naye bulina okutwalibwa ng’ekikulu ennyo. `(cystine)` bwe ekuŋŋaanyizibwa ennyo munda mu butoffaali, obutoffaali obwo busobola okwonooneka. Okubeera omutuufu, `(cystine)` eno ereetera obuwundo obutono okutondebwa munda mu butoffaali, era bwe bukuŋŋaanyizibwa, buleeta obuzibu eri ebitundu n’ebitundu by’omubiri eby’enjawulo mu mubiri gwaffe. Ka twogere ku `(Cystinosis)` eno mu bujjuvu era mu ngeri ennyangu leero, okay?

Obulwadde bwa Cystinosis kye ki? Tutegeere bulungi!

Mu ngeri ennyangu, obulwadde bwa cystinosis mbeera ya buzaale . Ekibaawo mu kino kiri nti amino asidi `(cystine)` (cysteine) ekuŋŋaanyizibwa munda mu butoffaali bwaffe. Omanyi amino acids nkulu nnyo eri omubiri gwaffe. Naye singa kino `(cystine)` kibeerawo ekisusse mu butoffaali, kiba kya bulabe eri obutoffaali. Olw’ekisusse kino `(cystine)` , obuwundo obutono ng’ebintu butondebwa munda mu butoffaali. Ebiwujjo bino bikuŋŋaanyizibwa mpolampola ne bitandika okwonoona ebitundu by’omubiri n’ebitundu by’omubiri eby’enjawulo mu mubiri gwaffe.

Obulwadde bwa Cystinosis businga kukwata nsigo n'amaaso . Wabula era kiyinza okwonoona obwongo, ebinywa, ekibumba, thyroid, olubuto, ate mu basajja, ensigo.

Kino tekitera kubaawo nnyo, ekitegeeza nti kikwata abantu nga omu ku buli lukumi. Kyokka, bulwadde bwa maanyi nnyo, obumala obulamu bwo bwonna . Wabula singa bumanyibwa nga bukyali ne bujjanjabwa obulungi, okukula n’okweyongera kw’obulwadde buno okusinga busobola okufugibwa. Wabula abantu bangi okukkakkana nga bafunye obulwadde bw’ekibumba obw’omutendera ogw’enkomerero ne beetaaga okusimbibwa ekibumba.

Waliwo ebika by’obulwadde bwa cystinosis obw’enjawulo?

Yee, waliwo ebika bisatu ebikulu eby’obulwadde bwa cystinosis. Ebika bino bigabanyizibwa okusinziira ku myaka obubonero gye busooka okulabika (i.e. obulwadde lwe bwatandika) n’obuzibu bw’obubonero.

1. Obulwadde bwa Nephropathic cystinosis (ekika ky’abaana abawere) .

Kino kye kika ekisinga okumanyibwa . Abantu nga 95% abalina obulwadde bwa cystinosis balina ekika kino. Era kye kika ekisinga okuba eky'amaanyi . Era kiyitibwa obulwadde bwa infantile cystinosis.

Abalongo abalina obulwadde buno obwa `(Nephropathic cystinosis)` bafuna embeera ey'enjawulo eyonoona ensigo . Kiyitibwa `(obulwadde bwa renal Fanconi syndrome)`. Mu mbeera eno, ebiriisa n’ebiriisa ebirala omubiri gwaffe bye gwetaaga tebiyingira bulungi mu musaayi, wabula bifulumizibwa mu musulo. Teeberezaamu, omubiri gw’omwana omuto bwe gufiirwa ebintu bye gwetaaga mu ngeri eno, .Okukula kw'omwana kukendeera, amagumba ganafuwa, gayinza okufukamira (kino era kiyitibwa ``rickets''), era ebizibu ebirala bingi bisobola okubaawo.

Ebiseera ebisinga, ku myaka ebiri , obutafaali obuyitibwa cystine crystals butandika okutondebwa mu cornea y’amaaso g’omwana. Ebiwujjo bino bikuŋŋaanyizibwa, era ekiseera bwe kigenda kiyitawo, amaaso gafuuka gawulirwa ekitangaala (photophobia). Kino kiyinza okuvaako obulumi obw'amaanyi mu maaso n'obutabeera bulungi . Kiringa amaaso okufuuka bbululu nga gafunye omusana.

Abaana abalina kino `(Nephropathic cystinosis)` mazima ddala beetaaga okusimbibwa ekibumba. Singa abaana bano tebajjanjabwa, basobola okulemererwa ddala okukola nga bawezezza emyaka 10. Kyokka singa bajjanjabwa obulungi, abaana bano basobola okuwangaala okutuuka ku bukulu nga balina obulamu obulungi.

2. Obulwadde bwa cystinosis obw’omu makkati (ekika ky’okutandika kw’abaana abato) .

Kino era kiyitibwa obulwadde bwa cystinosis obw’abavubuka oba abato. Obubonero buno bufaananako n’obw’obulwadde bwa cystinosis mu baana abawere, naye obubonero buno bulabika mu buto oba mu myaka gy’obutiini . Obubonero buyinza obutaba butono oba buyinza okweyongera okubeera obw’amaanyi oluvannyuma lw’ekiseera.

Abantu abalina obulwadde bwa cystinosis obw’ekika kino okukkakkana nga beetaaga okusimbibwa ekibumba. Singa tezijjanjabwa, ensigo ziyinza obutakola bulungi mu myaka 15-25 .

3. Obulwadde bwa Non-nephropathic cystinosis (ekika ekikwata amaaso gokka) .

Kino era kiyitibwa obulwadde bwa benign cystinosis oba ocular cystinosis. Ekika kino kikwata amaaso gokka . Cystine crystals zitondebwa mu cornea y’eriiso, ekivaako okutya ekitangaala. Wabula abantu abasinga obungi abalina ekika kino tebalina kwonooneka kwa kibumba oba obubonero obulala .

Emyaka embeera eno gy’ezuulibwa (Non-nephropathic cystinosis) giyinza okwawukana, kubanga obubonero tebutera kulabika. Kyokka kitera okukwata abantu abakulu abali mu myaka egy’omu makkati.

Ani afuna obulwadde bwa cystinosis?

Cystinosis mbeera ya buzaale eyinza okukwata omuntu yenna . Obulwadde buno busikira mu nkola ya autosomal recessive pattern. Kino kitegeeza nti abazadde bombi balina okubeera n'obuzaale obukyusiddwa olw'obulwadde buno . Singa abazadde bombi baba basitula obuzaale obukyusiddwa (ekitegeeza nti tebalina bubonero, naye nga balina obuzaale), balina emikisa gya 25% (omu ku bana) okuzaala omwana alina obulwadde bwa cystinosis.

Obulwadde buno butera kwenkana wa?

Obulwadde bwa Cystinosis bulwadde obutatera kulabika nnyo . Mu nsi yonna, bukosa omuntu omu yekka ku baana 100,000 okutuuka ku 200,000 abazaalibwa.

Obulwadde bwa cystinosis bukosa butya omubiri gwaffe?

Cystinosis bulwadde obubeera mu kibinja ky’endwadde eziyitibwa `(lysosomal storage disorder)`. Teebereza, munda mu butoffaali bwaffe mulimu obutundutundu obutono obuyitibwa `(lysosomes)` . Bino biringa ebidomola bya kasasiro eby’akasenge. Zimenya ebiriisa nga carbohydrates, proteins, n’amasavu. Puloteeni ezimu zikola nga `(enzymes)` era ziyamba omubiri okunyiga ebiriisa bino. Puloteeni endala ezimu zikola nga `(abatambuza)`. Kwe kugamba, abatambuza bano baggya `(cystine)` esigaddewo okuva mu bintu ebyo ebimenyese okuva mu lysosomes.

Kati, singa ofiirwa emu ku puloteyina ezo ez’entambula, `(cystine)` tesobola kuva mu lysosomes n’etandika okukuŋŋaanyizibwa munda mu butoffaali. Wano `(cystine)` w'ekola ebibinja, ebyonoona ebitundu by'omubiri.

Bubonero ki obulaga obulwadde bwa cystinosis?

Obubonero n’obuzibu bwabwo byawukana okusinziira ku myaka obulwadde gye butandikira ne ddi lwe buzuulibwa.

Obubonero bw’obulwadde bwa nephropathic cystinosis (infantile form) butera okutandika okulabika wakati w’emyezi 6 ne 18 egy’obukulu , ng’ensigo eyonoonese. Buno bwe bubonero obukulu:

• Ennyonta esukkiridde (polydipsia).
• Okufulumya omusulo ekisusse (polyuria).
• Obutakwatagana mu masanyalaze mu mubiri.
• Okusesema.
• Okubulwa amazzi mu mubiri.
• Omusujja.

Obubonero obulala buyinza okuli:

• Okunafuwa kw’amagumba, okuzimba.
• Okulemererwa okukulaakulana.
• Enkovu oba ebire ku cornea y’amaaso.
• Okuwulira ekitangaala (photophobia).
• Obuzibu mu kulaba.
• Okukaluubirirwa okumira (dysphagia).

Obubonero bw’obulwadde bwa intermediate cystinosis (juvenile form) bufaananako n’obw’abaana abawere. Kyokka, zitandika okulabika mu buto oba mu myaka gy’obuvubuka. Ate era, obubonero buyinza obutaba bwa maanyi nnyo. Obubonero obulala obuyinza okulabibwa mu ngeri eno mulimu:

• Obukoowu, obukoowu.
• Obunafu bw'ebinywa .
• Obulwadde bw’ebinywa `(myopathy)` (myopathy).
• Obuwanvu obumpi.
• Okulwawo okutuuka mu myaka gy’obuvubuka.
• Obutazaala.

Ocular cystinosis (non-nephropathic cystinosis) ekosa cornea y’eriiso yokka. Okutya ebifaananyi ebiseera ebisinga bwe bubonero bwokka . Tewali bubonero bukwata ku kibumba.

Biki ebivaako obulwadde bwa cystinosis?

Kino kiva ku nkyukakyuka mu buzaale mu buzaale obuyitibwa CTNS.. Ensengekera eno eya `(CTNS)` eragira omubiri gwaffe okukola puloteyina eyitibwa `(cystinosin)`. `(Cystinosin)` ye puloteyina etambuza eyayogeddwako emabegako. Kwe kugamba, omulimu gwayo kwe kuggya amino asidi `(cystine)` mu lysosomes.

Kale, bwe wabaawo enkyukakyuka mu ggiini ya `(CTNS)`, wabaawo ekikyamu mu puloteyina ya `(cystinosin)`. Olwo, `(cystine)` tesobola kuva mu lysosomes n’etandika okukuŋŋaanyizibwa. Wano ebizimba we bikola ne byonoona obutoffaali mu bitundu by’omubiri.

Kigambibwa okuva edda nti kino kisikira mu ``autosomal recessive pattern''. Kino kitegeeza nti abazadde bombi balina okuba nga basitula obuzaale buno obukyusiddwa (tebalina bubonero) . Singa abazadde bombi basikira obuzaale buno obukyusiddwa, omwana y’ajja okufuna obulwadde buno.

Obulwadde bwa Cystinosis buzuulibwa butya?

Omusawo ajja kukubuuza ku bubonero bwo n’ebyafaayo by’obujjanjabi bw’amaka go. Olwo ajja kukeberebwa omubiri era alagire okukeberebwa okuwerako okuzuula embeera eno.

Kino kigezo ki ekikolebwa?

Omusawo ayinza okukola ebigezo bino:

• Okukebera omusaayi: Baggyibwako sampuli y’omusaayi gwo ne bakeberebwa omuwendo gwa cystine mu butoffaali obweru.
• Okukebera obuzaale: Omukugu mu by’obuzaale ajja kukebera oba waliwo enkyukakyuka mu buzaale bwo obwa CTNS.
• Okwekenenya omusulo: Sampuli y’omusulo bagiggyibwa ne bakeberebwa oba temuli mineral, ebiriisa, eminnyo ne amino acids ezisukkiridde.
• Okukebera amaaso: Omusawo w’amaaso ajja kukozesa microscope ey’enjawulo (eslit lamp) okunoonya cystine crystals mu cornea yo.

Bw’oba ​​oli lubuto ate ng’omuntu mu maka go alina obulwadde bwa cystinosis, era nga ggwe ne munno mwembi muzuuliddwa nti mulina obulwadde buno, okukeberebwa nga tonnazaala, gamba nga amniocentesis, kuyinza okukolebwa okuzuula oba omwana wo alina obulwadde buno . Kino kizingiramu okuggya sampuli y’obutoffaali okuva mu mazzi g’omu lubuto ageetoolodde omwana n’okukebera emiwendo gya cystine.

Okugezesebwa okulala okuyitibwa ``chorionic villus sampling`` nakyo kisobola okukozesebwa. Kino kikebera obutoffaali obuli mu nnabaana.

Bujjanjabi ki obw’obulwadde bwa cystinosis?

Eddagala eriyitibwa Cysteamine

Obujjanjabi obusinga ku bulwadde bwa cystinosis ddagala eriyitibwa cysteamine . Kino kirungo ekikendeeza ku cystine. Kino kitegeeza nti kikendeeza ku miwendo gya cystine mu butoffaali bwo.

Singa eddagala lino `(cysteamine)` litandikibwa nga bukyali, okwonooneka kw’ekibumba okusinga kuyinza okufugibwa n’okulwawo.. Eddagala lino liyambye okulwawo obwetaavu bw’okusimbuliza ekibumba. Abaana abamu basobodde okulwawo okusimbuliza ekibumba okutuusa lwe bakula. Ekirala eddagala lino litereeza enkula y’abaana abalina obulwadde buno.

Waliwo ebika bibiri ebya `(Cysteamine)`: `(CystagonTM)` ne `(ProcysbiTM)` (gano mannya ga kika). `(CystagonTM)` erina okumira buli luvannyuma lwa ssaawa mukaaga. `(ProcysbiTM)` (eri abo abasukka mu myaka 6) erina ekizigo eky’enjawulo, kale osobola okugimira buli luvannyuma lwa ssaawa 12.

Eddagala erya bulijjo `(cysteamine)` terijjanjaba `(cystine)` crystals mu cornea y'eriiso. Ku kino, waliwo ebika bibiri eby’amatondo g’amaaso aga `(cysteamine)` agakkirizibwa ekitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala `(FDA): `(CystaranTM)` ne `(CystadropsTM)`. Amatondo gano olina okugasiiga omulundi gumu mu ssaawa ng’ozuukuse. Zisaanuusa obuwundo obuli mu kitundu ky’amaaso (cornea) ne bukendeeza ku buwulizi bw’ekitangaala.

Enzijanjaba endala

Abaana abalina obulwadde bwa cystinosis bayinza okwetaaga obujjanjabi obulala, okusinziira ku bubonero bwabwe. Obujjanjabi bw’obulwadde bwa Fanconi syndrome mulimu:

• Nywa amazzi mangi n’ebirungo ebikola amasannyalaze (okuziyiza amazzi okufiirwa ennyo okuva mu mubiri).
• Eddagala okukuuma bbalansi y’omunnyo mu mubiri.
• Eddagala okutereeza ekikyamu mu kunyiga ekirungo kya phosphate ekibumba.

Obujjanjabi obulala obw’obulwadde bwa cystinosis mulimu:

• Obujjanjabi bw’obusimu bw’okukula.
• Bw’oba ​​olina obulwadde bwa sukaali obusinziira ku insulini, weetaaga insulini.
• Testosterone eri abasajja abalina obulwadde bwa hypogonadism.
• Obujjanjabi bw’okwogera n’olulimi.
• Okubuulirira ku buzaale.

Abaana abamu abafuna obuzibu mu kulya bayinza okwetaaga okuliisibwa nga bayita mu ttanka (gastronomy tube). Tubu eno ekozesebwa okuwa endya entuufu n’okugaba eddagala.

Obulwadde bwa ocular cystinosis obukwata amaaso gokka era busobola okujjanjabibwa mu ngeri zino wammanga:

• Okwewala ekitangaala ekimasamasa.
• Okwambala engatto z’omusana.
• Okukuuma amaaso nga mayonjo.
• Tekitera nnyo, okukyusa amaaso kiyinza okwetaagisa.

Okukyusa ekibumba

Ne bwe baba bazuuliddwa nga bukyali n’okujjanjabibwa, abantu abalina obulwadde bw’ekibumba n’obulwadde bwa cystinosis obw’omu makkati batuuka n’okulemererwa ekibumba. Mu kusooka, omusawo wo ayinza okujjanjaba ekibumba okulemererwa ng’akozesa dialysis. Okulongoosa omusaayi kyuma ekitwala ogumu ku mirimu ensigo zo gye zikola. Asengejja kasasiro okuva mu musaayi gwo n’ayamba okukuuma emiwendo emituufu egy’eddagala erimu mu mubiri gwo. Kyokka, okulemererwa kw’ekibumba tekikyuka, era okukkakkana ng’ekibumba kyetaagisa okukyusa .

Okukyusa ekibumba kukola bulungi nnyo eri abantu abalina obulwadde bwa cystinosis. Ekibumba ekiweereddwayo tekikung'aanya cystine . Wabula cystine akyayinza okukuŋŋaanyizibwa mu bitundu by’omubiri ebirala mu mubiri gwo. N’olwekyo, ojja kuba olina okumira eddagala obulamu bwo bwonna .

Waliwo ebizibu byonna ebiva mu bujjanjabi buno?

Eddagala `(cysteamine)` lirina akawoowo akabi katono ate nga liwooma obutanyuma . N’olwekyo, abantu abamu bayinza okuziyira, okusesema, n’okulumwa omutima nga bamira eddagala lino. `(cysteamine)` era asobola okuvaako asidi w'olubuto ayitiridde okuvaamu. Abantu abamu bamira eddagala nga `(proton pump inhibitors)` okukendeeza asidi mu lubuto. Kino kiyinza okukendeeza ku bubonero bwabwe obw’omu lubuto. `(cysteamine)` era esobola okuleeta okuwunya obubi `(halitosis)` n'okuwunya okuwunya.

Obulwadde bwa Cystinosis busobola okuziyizibwa?

Obulwadde bwa Cystinosis mbeera ya buzaale, n’olwekyo tesobola kuziyizibwa . Bw’oba ​​oli lubuto oba ng’oteekateeka okufuna olubuto, oyinza okwagala okulowooza ku ky’okukebera obuzaale okuzuula oba omwana wo ali mu bulabe bw’okufuna obulwadde buno.

Endowooza etya eri omuntu alina obulwadde bwa cystinosis? / Bayinza okuwangaala ebbanga ki?

Ekiseera ekimu, obulwadde bwa nephropathic cystinosis bwali bulwadde obutta abaana abato. Naye leero, olw’okukulaakulanya eddagala eriyitibwa cysteamine n’okukulaakulana mu kukyusa ekibumba, obulamu bw’abantu abalina obulwadde bwa cystinosis bugaziyiziddwa okutuuka mu bukulu . Abantu abamu bawangaala okutuuka ku myaka egisukka mu 50.

Okuzuula amangu obulwadde bwa cystinosis kikulu. Singa obulwadde buno bujjanjabiddwa bulungi, busobola okufugibwa. Singa tebajjanjabwa, abaana abalina obulwadde bwa cystinosis bajja kulemererwa ekibumba nga bawezezza emyaka 10. Ne bwe baba bajjanjabiddwa, abaana bangi bajja kulemererwa ekibumba mu buto oba mu myaka gy’obuvubuka. Kino kijja kwetaagisa okulongoosebwa ekibumba okukkakkana ng’akyusiddwa ekibumba.

Bw’oba ​​omira eddagala lya cysteamine, olina okugenda mu maaso n’okulimira obulamu bwo bwonna . Okunoonyereza kulaga nti esobola okuziyiza ebizibu bingi ebilwawo ebiva mu bulwadde bwa cystinosis obutakwatagana na nsigo.

N’ekisembayo, ebintu by’olina okujjukira

Obulwadde bwa Cystinosis mbeera ya buzaale eyinza okuleeta obubonero obw’enjawulo. Singa kizuulibwa nga bukyali era n’ajjanjabwa mangu, okukulaakulana kw’obulwadde buno okusinga kuyinza okufugibwa . Obulwadde buno edda nga butta abaana abato, kati busobola okujjanjabibwa n’eddagala. Ne bwe baba n’eddagala, abantu abalina obulwadde bwa cystinosis batuuka n’okulemererwa ekibumba ne beetaaga okusimbibwa ekibumba. Kyokka kati abantu abalina obulwadde buno bawangaala bulungi okutuusa lwe bakula.

Bw’oba ​​ggwe oba omuntu gw’omanyi alina obubonero buno, kikulu nnyo okugenda mu basawo amagezi mu bwangu.Teweeraliikiriranga naye kirungi buli muntu okubeera nga amanyi ebintu nga bino.

` cystinosis, cystine, obulwadde bw’ekibumba, obuzibu mu buzaale, Fanconi syndrome, cysteamine, obulwadde bw’ekibumba, obulwadde bw’obuzaale, obulamu bw’abaana
