Olina ammonia mungi mu musaayi gwo? Ka tuyige ku mbeera ey'akabi ey'obulwadde bwa hyperammonemia!

Ebintu bingi nnyo ebigenda mu maaso munda mu mibiri gyaffe, nedda? Oluusi, enkola zino bwe zigenda mu maaso katono, ebizibu ebinene bisobola okuvaamu. Okugeza, obulwadde bwa ‘hyperammonemia ’ mbeera ya maanyi ebaawo ng’ekintu ekicaafu ekiyitibwa ammonia yeeyongedde mu musaayi gwaffe. Kino kikulu nnyo okukimanya kubanga kiyinza okukosa ennyo obulamu bwo singa tolabirirwa bulungi.

Obulwadde bwa Hyperammonemia kye ki?

Mu ngeri ennyangu, hyperammonemia bwe buba nga ammonia mu musaayi gwo eri waggulu mu ngeri etaali ya bulijjo. Ammonia oba NH3, kasasiro akolebwa mu byenda byaffe nga tugaaya puloteyina ze tulya. Mu budde obwabulijjo, ammonia ono agenda mu kibumba kyaffe n’alongoosebwa eyo. Enkola eno tugiyita enzirukanya ya urea . Okuyita mu nsengekera eno, ammonia akyusibwa n’afuuka ekintu ekitali kya bulabe nnyo ekiyitibwa urea n’afulumizibwa mu musulo. Wabula singa wabaawo ekikyamu mu nsengekera eno eya urea, oba ekibumba bwe kiba nga tekisobola kukola bulungi ammonia ono, ammonia etandika okukuŋŋaanyizibwa mu musaayi. Okweyongera kuno okwa ammonia mu musaayi kwa butwa nnyo eri Central Nervous System yaffe (CNS) , nga eno ye bwongo n’omugongo. Eno y’ensonga lwaki obulwadde bwa hyperammonemia mbeera eyeetaaga okujjanjabibwa amangu era eyinza n’okuteeka obulamu mu matigga .

Ani ayinza okusinga okukulaakulanya kino?

Embeera eno eyitibwa hyperammonemia, esobola okukwata abalongo, abaana abato n’abantu abakulu.

• Mu bantu abakulu, nga 90% ku abo abatawaanyizibwa embeera eno bebo abalina obulwadde bwa cirrhosis of the liver .
• Abalongo abaakazaalibwa basobola okufuna kino kubanga bazaalibwa n’ekikyamu mu nsengekera ya urea (congenital urea cycle disorder) . Zino mbeera za buzaale.
• Ate era, ekibumba okulemererwa ennyo n’endwadde z’enkyukakyuka mu mubiri ezisikira bisobola okuleeta obulwadde bwa hyperammonemia mu baana abato.

Kizibu okwogera ddala engeri kino gye kitera okubaawo, kuba kiyinza okuva ku bintu eby’enjawulo. Naye abanoonyereza bateebereza nti obuzibu bw’okutambula kwa urea, ekimu ku buvaako, bukosa omwana omu ku buli baana 250,000 abazaalibwa mu Amerika ate omu ku buli baana 440,000 abazaalibwa mu nsi yonna.

Biki ebivaako obulwadde bwa hyperammonemia?

Kino kiyinza okubaawo ensonga eziwerako. Ensonga zino zisobola okukyuka n’emyaka. Naye okutwaliza awamu, bibiri ku bisinga okuvaako bye bizibu by’ekibumba n’obuzibu bw’enzirukanya ya urea (UCDs) .

Olw’obuzibu bw’ekibumba

Ekibumba kyaffe kye kitundu ekikulu ekikyusa ammonia okufuuka urea. Kale ekibumba bwe kiba kyonoonese oba ekirwadde, tekisobola kukola bulungi ammonia. Wano ammonia w’azimba mu musaayi. Wano waliwo embeera ezikwatagana n’ekibumba eziyinza okuvaako obulwadde bwa hyperammonemia:

• Obulwadde bw'ekibumba : Ekibumba bwe kyonoonese , obusobozi bwakyo okukola ammonia buba butono. Kino kisinga kubeera mu bulwadde bw’ekibumba obw’amaanyi, naye ne mu bantu abalina obulwadde bw’ekibumba obutakyukakyuka, omuwendo gwa ammonia oluusi guyinza okulinnya mu bwangu, okugeza, singa wabaawo ekintu ekibaawo mu lubuto oba mu byenda ( okuvaamu omusaayi mu lubuto ) oba singa wabaawo obutakwatagana mu byuma by’amasannyalaze . Kino kye kisinga okuvaako ammonia okubeera omungi mu bantu abakulu n’abaana.
• Hepatic encephalopathy : Kino kibaawo ng’ekibumba kyonoonese era nga tekisobola kukola bulungi ammonia. Ammonia yeeyongera mu musaayi n’agenda mu bwongo. Kino kiyinza okuvaako okutabulwa, okutabulwa , n’okutuuka n’okubeera mu kkoma. Oluusi kiyinza okutta omuntu.
• Obulwadde bw’ekibumba: Obulwadde bw’ekibumba kwe kukyusa ebitundu by’ekibumba ebiramu n’ossaamu enkovu. Kino kiyinza okuvaako ekibumba obutakola bulungi era kiyinza okuvaako obulwadde bwa hyperammonemia. Obulwadde bwa Cirrhosis bulwadde bwa kibumba obutawona.
• Acute liver failure: Kino kye kiseera ekibumba bwe kilekera awo okukola mu bwangu. Kiyinza okuva ku ndwadde n’embeera ez’enjawulo. Okugeza, obuvune bw’ekibumba obuva ku ddagala obuva ku ddagala erimu, gamba nga acetaminophen , bukola ebitundu 50% ku misango gyonna egy’okulemererwa kw’ekibumba okw’amaanyi mu Amerika. Kikola ebitundu 64% ku balwadde ba hyperammonemia mu baana.
• Okukendeera kw’omusaayi mu kibumba kyo: Singa omusaayi tegutambula bulungi mu kibumba kyo, omubiri tegusobola kusindika ammonia mu kibumba okulongoosebwa. Ne mu kiseera ekyo, ammonia yeeyongera mu musaayi.
• Obulwadde bwa Reye:Eno mbeera ya bbula nnyo. Kikosa omusaayi, obwongo n’ekibumba. Ebiseera ebisinga kivaako ammonia okulinnya mu musaayi n’okukendeera kwa glucose mu musaayi. Businga kukwata baana bato n’abakadde abawona obulwadde bw’akawuka nga ekifuba oba ssennyiga/ssennyiga era nga bamira aspirin olw’obubonero obwo. Ekituufu ekivaako obulwadde bwa Reye’s syndrome tekimanyiddwa. Wabula olw’akabi kano, aspirin tasaanidde kuweebwa baana bato n’abakadde okuggyako ng’omusawo alagiddwa mu ngeri ey’enjawulo.

Olw’obuzibu bw’enzirukanya ya Urea (UCDs) .

Nga bwe twayogeddeko emabegako, enzirukanya ya urea y’enkola ammonia ow’obutwa gy’akyusibwa n’afuuka urea n’afulumizibwa mu musulo. Enzirukanya eno erina emitendera egiwerako, nga buli emu yeetaaga ekika ky’enziyiza eky’enjawulo. Enziyiza zino ze zino:

• N-asetil-glutamate synthase (NAGS) .
• Ekirungo kya carbamoyl phosphate synthetase (CPS) .
• Ekirungo kya Ornithine transcarbamylase (OTC) .
• Ekirungo kya argininosuccinate synthetase (AS) .
• Asidi ya argininosuccinic yaasi (ASL) .
• Ekirungo kya Arginase (ARG1) .

Singa emu ku enzymes zino eba ebula, enzirukanya ya urea tekola bulungi. Ammonia yeeyongera mu musaayi. Ekika kino eky’obutaba na enzyme kiyitibwa obuzibu bw’okutambula kwa urea (UCD). UCDs zisobola okuleeta obulwadde bwa hyperammonemia, ekiyinza okuba obw’amangu oba obutawona. UCDs mbeera za kuzaalibwa. Abalongo ababulwa ddala enziyiza ya urea cycle batera okufuna obulwadde bwa acute hyperammonemia mu ssaawa 24 ku 72 nga bamaze okuzaalibwa. Ka kibe nti obutaba na enzyme butono oba kitundu, okuzimba ammonia kuyinza okubaawo ekiseera kyonna mu bulamu, mu kiseera ky’obulwadde, situleesi, oba ebintu ebirala ebinyigiriza. UCD zino zikola ebitundu 23% ku balwadde ba acute hyperammonemia mu baana abato abalwadde ennyo.

Ensonga endala

Ng’oggyeeko kino, wayinza okubaawo ensonga endala eziwerako:

• Okulemererwa kw’ekibumba (ekibumba): Singa enkizi tezisobola kufulumya bulungi urea olw’ekibumba okulemererwa, kiyinza okuvaako ammonia okukuŋŋaanyizibwa mu musaayi.
• Ebizibu ebimu eby’omusaayi: Hyperammonemia era eyinza okuva ku buzibu bw’omusaayi nga multiple myeloma ne acute leukemia.
• Yinfekisoni ezimu: ebiramu ebikola urease nga Proteus mirabilis , Escherichia coli (E. coli) ne KlebsiellaYinfekisoni za bakitiriya nga streptococci naddala mu baana abazaalibwa n’obulema mu nkola y’omusulo ne mu bantu abakulu abalina obuzibu bw’okufulumya omusulo olw’obulwadde bw’omusulo (UTIs), zisobola okuleeta obulwadde bwa hyperammonemia obw’amaanyi.

Bubonero ki obulaga obulwadde bwa Hyperammonemia?

Obubonero buyinza okwawukana ennyo okusinziira ku ngeri embeera eno gy’eri ennyangu oba ey’amaanyi, awamu n’emyaka gy’ekula.

Obubonero obutono obutera okubeera mu baana n’abantu abakulu

• Okuziyira n’okusiiyibwa
• Obulumi mu lubuto
• Okunyiiga ennyo
• Okulumwa omutwe (okulumwa omutwe) .
• Obuzibu mu bbalansi, okukwatagana, n‟okwogera (ataxia) .
• Enkyukakyuka mu nneeyisa

Obubonero obulala obutono obukwata abaana bokka

• Okulemererwa okukulaakulana
• Obunafu bw’ebinywa (hypotonia) .
• Okulwawo kw’enkula y’obusimu

Obubonero obw’amaanyi mu baana n’abantu abakulu

Buno bubonero bwa bulabe nnyo. Bw’oba ​​olina ekimu ku bino, olina okugenda mu basawo amagezi mu bwangu.

• Okutabulwa n’okutaataaganyizibwa
• Embeera ekyukakyuka
• Otulo otuyitiridde
• Enkyukakyuka mu kutegeera
• Okukonziba
• Okussa amangu (Hyperventilation) .
• Coma

Okulabula: Singa ggwe oba omuntu ali ku lusegere lwo alina obubonero buno, nsaba kuba 911 mu bwangu, oba genda mu kitongole ky’abalwadde ab’amangu mu ddwaaliro erikuli okumpi. Ammonia bw’alinnya mu musaayi kitta omuntu era kyetaagisa okujjanjabibwa amangu!

Obubonero mu baana abaakazaalibwa

Singa omwana eyaakazaalibwa akoseddwa obulwadde bwa hyperammonemia, obubonero buno wammanga butera okulabika mu ssaawa 24 ku 72 ng’azaalibwa:

• Okunyiiga ennyo, okukaaba ennyo
• Okusesema
• Obukoowu
• Okukonziba
• Okuwuuma ng’ossa
• Okussa amangu (Hyperventilation) .

Ekikulu: Omwana bw’aba alaga obubonero buno, ssimu mangu omusawo bw’oba ​​okyali mu ddwaaliro. Bw’oba ​​oli waka, kuba 911 mu bwangu, oba batwale mu ddwaaliro erikuli okumpi. Kino si kintu kya kulwawo.

Abasawo kino bakizuula batya ?

Abasawo batera okuteebereza nti obulwadde bwa ‘hyperammonemia’ nga bakebera omuwendo gwa ammonia mu musaayi.

• Ku balongo abatuuka ku mwezi gumu, singa ammonia mu musaayi esukka 80 micromol/liter (80 micromol/L).
• Ku baana abakulu, singa kiba kisukka 55 micromol/liter (55 micromol/L).
• Mu bantu abakulu, singa eba esukka 30 micromol/liter (30 micromol/L).

Ekitundu kino eky’okupima (micromol/L) ngeri ya kupima bungi bwa ammonia mu musaayi.

Bikebere ki ebikolebwa okuzuula kino?

Okukebera okukulu kwe kukebera omusaayi nga kupima omuwendo gwa ammonia mu musaayi gwo. Singa ammonia mungi, omusawo ayinza okukola okukebera okulala okuzuula ekivaako. Okugeza, okukebera omusaayi okukebera enkola y’ekibumba kyo n’enkola y’ekibumba , awamu n’okukebera omusulo . Olw’okuba obulwadde bwa hyperammonemia busobola okwonoona obusimu obw’omu makkati era nga buyinza okutta omuntu, omusawo wo ayinza n’okukebera ebifaananyi, gamba nga CT (computed tomography) scan oba MRI (magnetic resonance imaging) scan, okukebera oba waliwo ebizibu ebikosa obwongo.

Bujjanjabi ki obuweebwa obulwadde bwa hyperammonemia?

Obujjanjabi businziira ku kivaako. Okugeza mu muntu omukulu, kiva ku bulwadde bw’ekibumba oba obulwadde bw’ekibumba, oba mu mwana omuwere, kiva ku bulwadde bwa urea cycle disorder (UCD). Mu acute hyperammonemia, ekigendererwa ekikulu kwe kukendeeza ku muwendo gwa ammonia mu musaayi n’okufuga ebizibu ebitongole nga okuzimba obwongo n’okweyongera kwa puleesa okwetoloola obwongo (intracranial hypertension).

• Singa omwana eyaakazaalibwa aba n’obulwadde bwa ‘hyperammonemia’, abasawo bajja kulekera awo okubawa puloteyina (kubanga ammonia akolebwa nga puloteyina agayiridde) mu kifo ky’ekyo bamuwe glucose, ekirungo kya ssukaali, okusobola okufuna kalori. Era bagenda kukozesa enkola eyitibwa hemodialysis . Kino kizingiramu okuyonja omusaayi gw’omwana n’okuggyawo ammonia ng’oyita mu kyuma ekirongoosa omusaayi n’ekyuma ekisengejja eky’enjawulo (nga ekibumba eky’obutonde).
• Abantu abalina obulwadde bwa partial urea cycle enzyme deficiency (UCD) abafuna hyperammonemia olw’okunyigirizibwa, gamba nga stress-induced hyperammonemia, nabo baweebwa protein withdrawal ne glucose nga calories. Okulongoosa omusaayi kukolebwa singa ammonia yaabwe tekendeera mu ssaawa ntono oluvannyuma lw’okusooka okujjanjabwa.
• Obujjanjabi bw’obulwadde bw’obwongo mu kibumba kwe kukendeeza ku kukola ammonia mu byenda. Obujjanjabi obusooka bwe ddagala eriweebwa mu kamwa nga lirimu lactulose ne lactitol . Ssukaali ono akendeeza ku kukola n’okunyiga ammonia mu byenda.

Abasawo bayinza okukuwa amagezi ku mmere nga zino okuyamba abantu abalina obuzibu mu kutambula kwa urea okukendeeza ku mirundi gy’obubonero bwabwe:

• L-carnitine, eddagala eriyitibwa L-carnitine
• L-ornithine-L-aspartati (omubisi gw’enjuki).
• Arginine, eddagala eriweweeza ku bulwadde

Waliwo engeri gye tuyinza okwewala embeera eno?

Olw’okuba waliwo ebintu bingi ebivaako obulwadde bwa hyperammonemia, embeera zonna teziyinza kuziyizibwa. Wabula osobola okukola emitendera okutangira ebika by’endwadde z’ekibumba ezimu naddala ezikwatagana n’endya yo n’engeri gy’obeera. Bw’oba ​​oli mu bulabe bw’okulwala ekibumba, omusawo ayinza okukuwa amagezi okukola enkyukakyuka zino mu bulamu bw’omuntu:

• Si kibi okwewala oba okussa ekkomo ku kunywa omwenge.
• Weewale emmere n’ebyokunywa ebirimu amasavu aga ‘trans fats’ oba ‘high-fructose corn syrup’.
• Okwewala okwonooneka kw’ekibumba, weegendereze nnyo ng’okozesa eddagala eriwandiikiddwa omusawo n’erya ddagala eritali ku ddagala.
• Okukola dduyiro buli kiseera .
• Okussa ekkomo ku kulya ennyama emmyufu.

Okuziyiza obulwadde bwa Reye’s syndrome, embeera ereeta hyperammonemia mu baana n’abavubuka abakulu, towa baana aspirin olw’obubonero bw’obulwadde bw’akawuka (nga ssennyiga oba ekifuba) okuggyako ng’omusawo akugambye mu ngeri ey’enjawulo. Obulema mu nsengekera ya urea (UCDs) tebutera kubaawo, naye waliwo okukebera obuzaale okulaba oba olina obuzaale obubuleeta. Yogerako n’omusawo wo ku nsonga eno.

Kiki ekitegeeza embeera eno?

Endowooza y’obulwadde bwa hyperammonemia, kwe kugamba, obusobozi bw’okuwona, esinziira ku bintu ebiwerako:

• Engeri omuwendo gwa ammonia gwo gye guli waggulu.
• Ebbanga ki omuwendo gwa ammonia gwe gubadde gulinnyisibwa.
• Kiki ekivaako obulwadde bwa hyperammonemia?

Okutwalira awamu, entunula y’obulwadde bwa hyperammonemia mbi. Singa tebajjanjabwa oba okujjanjabibwa ekikeerezi, okuzimba obwongo obutakyuka kukwatagana n’omuwendo gw’abafa omungi. Ebyembi, ne bw’anaajjanjabwa amangu oba mu ngeri ey’obukambwe n’obulwadde bwa hyperammonemia obw’amaanyi, tewali bukakafu nti ebinaavaamu bijja kuba birungi. Mu Amerika, omuwendo gw’abantu abawangaala mu myaka 11 eri abantu abalina obuzibu mu urea cycle defects (UCDs) abafuna obulwadde bwa hyperammonemia nga bakyali bato guli nga 35%. Ku abo abafuna obulwadde bwa hyperammonemia nga bakuze, omuwendo gw’abawangaala guli nga 87%. Emiwendo gy’okuwangaala omwaka gumu n’emyaka esatu egy’abalwadde abalina obulwadde bw’ekibumba obw’amaanyi olw’obulwadde bwa hyperammonemia gibadde gitegeezeddwa okuba 42% ne 23%, okusinziira ku.

Bizibu ki ebiyinza okuva mu hyperammonemia?

Singa embeera eno tejjanjabibwa mangu, omuwendo gwa ammonia ogw’amaanyi guyinza okwonoona enkola y’obusimu obw’omu makkati ne kivaako ebizibu ebiyinza okutta omuntu. Ebizibu ng’ebyo mulimu:

• Okuzimba kw’obwongo
• Okwongera ku puleesa okwetoloola obwongo (Intracranial hypertension) .
• Brain herniation – Kino kisinga kuva ku kuzimba bwongo n’okweyongera puleesa okwetoloola obwongo.
• Coma
• Okufa

Singa omuntu alina obulwadde bwa chronic mild hyperammonemia okumala ebbanga eddene, ayinza okufuna obulemu ku magezi n’obuzibu obw’olubeerera mu nneeyisa n’eby’omutwe.

Ddi lwe tusaanidde okulaba omusawo?

Bw’oba ​​ggwe oba omuntu gw’ofaako alina obubonero bw’obulwadde bwa hyperammonemia, kuba 911 mu bwangu oba genda mu ddwaaliro erikuli okumpi. Kino si kintu kya kulwawo. Bw’oba ​​olina obulwadde bw’ekibumba oba obutaba na enzyme ya urea cycle ekitundu, kikulu nnyo okulaba omusawo buli kiseera okuddukanya embeera yo n’okulondoola omuwendo gwa ammonia.

Hyperammonemia mbeera ya maanyi era eyinza okuva ku bintu ebiwerako. Singa ggwe, omwana wo oba omwana wo mulina obubonero buno, noonya obuyambi amangu ddala. Bw’oba ​​olina obulwadde bw’ekibumba, oba omuntu mu maka go bw’aba alina obuzibu bw’okutambula kw’ekibumba (UCDs), yogerako n’omusawo wo ku bulabe bw’okufuna obulwadde bwa hyperammonemia. Baliwo okukuyamba.

N’ekisembayo, kino kijjukire.

Okay, kale bino bye bimu ku bintu ebikulu by’olina okujjukira okuva mu bye twogeddeko:

• Hyperammonemia ye ammonia omungi mu musaayi mu ngeri ey’akabi. Kino kya bulabe nnyo eri obwongo bwaffe n’obusimu bwaffe.
• Kino kiyinza okubaawo ensonga eziwerako. Obuzibu mu kibumba n’obuzibu bw’okutambula kwa urea (UCDs) bye bisinga okuvaako.
• Obubonero bwawukana okusinziira ku buzibu bw’embeera n’emyaka. Ziyinza okuva ku bubonero obutono ng’okuziyira, okusiiyibwa, n’okulumwa omutwe okutuuka ku bubonero obw’amaanyi ennyo ng’okutabulwa, okukonziba, n’okugwa mu kkoma. Abalongo nabo balina okweraliikirira naddala ku bubonero bwabwe.
• Bw’oba ​​olina obubonero obw’amaanyi, olina okugenda ew’abasawo awatali kulwa. Eno eyinza okuba embeera ey’obulamu oba okufa.
• Obujjanjabi businziira ku kivaako. Obujjanjabi obw’amangu busobola okukendeeza ku muwendo gwa ammonia n’okufuga ebizibu.
• Wadde ng’ebimu ku bivaako tebisobola kuziyizibwa, akabi akamu kasobola okukendeezebwa ng’okuuma obulamu obulungi n’okulabirira ekibumba kyo .
• Oba olina obulwadde bw’ekibumba oba omuntu mu maka go alina UCDs, kikulu okwekebeza abasawo buli kiseera.

Tewerabira, ggwe osinga okumanya obulamu bwo. Bw’oba ​​owulira ekintu kyonna eky’enjawulo oba ekitali kya bulijjo, totya kwogera na musawo. Hyperammonemia, ammonia, ekibumba, urea cycle, obwongo, obubonero, obujjanjabi
