Omanyi obulwadde bwa Erdheim-Chester? Ka twogere ku mbeera eno etali ya bulijjo!

Wali owuliddeko ku bulwadde bwa Erdheim-Chester Disease (ECD)? Oyinza okuba nga weewuunya katono ng’owulira erinnya lino. Kubanga buno bulwadde bwa bbula nnyo era nga tebutera kulabibwa mu nsi. Kyokka olw’okuba kisobola okukosa enkola z’ebitundu by’omubiri eby’enjawulo mu mubiri gwaffe, kya mugaso nnyo okukimanyaako katono. Kale leero, ka twogere ku bulwadde bwa Erdheim-Chester Disease (ECD).

Obulwadde bwa Erdheim-Chester (ECD) kye ki?

Mu ngeri ennyangu, obulwadde bwa Erdheim-Chester (ECD) bulwadde bwa musaayi obutatera kulabika nnyo. Kibeera mu kibinja ky'endwadde eziyitibwa histiocytosis . Kati oyinza okuba nga weebuuza nti histiocytes zino ze ziruwa. Histiocytes kika kya butoffaali kya njawulo mu baserikale baffe abaserikale b'omubiri . Balinga abaserikale abato abakuuma emibiri gyaffe. Obutoffaali buno butera okusangibwa mu bifo ng’amagumba gaffe, omusaayi, olususu, amawuggwe, enseke n’ekibumba.

Kyokka, mu muntu alina obulwadde bwa Erdheim-Chester (ECD), obusimu buno obuyitibwa histiocytes bukula mu ngeri etafugibwa . Kiringa okuba n'abajaasi abangi ennyo. Histiocytes zino ez’enjawulo zitandika okukula mu bitundu by’omubiri eby’enjawulo we zitasaanidde. Olwo zisobola okukola ebizimba ne zoonoona ebitundu ebiramu . Kino kye kibaawo mu ECD.

Obulwadde buno butera kwenkana wa?

Nga bwe twagambye emabegako, buno bulwadde bwa bbula nnyo . Lowooza ku kino, okuva obulwadde buno lwe bwasooka okuzuulibwa mu 1930, wabaddewo abantu nga 800 bokka abakwatibwa mu nsi yonna. Kyokka abasawo abamu balowooza nti omuwendo guno guyinza n’okusingawo kubanga abantu abamu abalina obulwadde buno tebazuulibwa bulungi. Kino era kiyinza okuba nga kiva ku kuba nti amawanga okwetoloola ensi yonna mu kiseera kino tegalina nkola ya wamu ey’okukuuma ebiwandiiko by’abalwadde bano.

Obulwadde bwa Erdheim-Chester (ECD) businga kubeera mu bantu abakulu ab’emyaka egy’omu makkati . Mu Amerika, emyaka gy’okuzuulibwamu obulwadde buno gya myaka 46. Wabula kibadde kitegeezeddwa mu baana abato ennyo. Ekirala abasajja batera okukwatibwa obulwadde buno. Kigambibwa nti abalwadde wakati wa 70% ne 75% basajja.

Obubonero bwe buliwa?

Engeri obulwadde bwa Erdheim-Chester (ECD) gye bukosaamu buli muntu ya njawulo nnyo . Kino kitegeeza nti si buli muntu nti alina obubonero bwe bumu. Obubonero businziira ku bitundu by’omubiri ebyonooneddwa obuwuka obuyitibwa histiocytes obusukkiridde, nga bwe twayogeddeko emabegako, n’enkola z’ebitundu ki ezikosebwa. Oluusi, obulwadde buno busobola okubaawo nga tebulaze bubonero bwonna (obubonero). Mu mbeera eyo, omusawo afuna ekisumuluzo ku nsonga eno okuva mu sikaani (`imaging`) oba okukebera omusaayi (`lab tests`) okukolebwa olw'ensonga endala.

Katutunuulire enkola z’ebitundu by’omubiri ezisinga okukosebwa n’obubonero obukwatagana nazo.

Engeri gye kikwata ku magumba

ECD esobola okuleeta amagumba okugonza mu ngeri etaali ya bulijjo (osteosclerosis). Kino oluusi kiyinza okuvaako amagumba okulumwa . Akabonero akasinga okulabika mu bulwadde buno kwe kugonza amagumba n’okulumwa naddala mu magulu gombi . Okugonza kw’amagumba kuno kuyinza okulabibwa bulungi ku sikaani.

Effect ku nsigo

Ensigo zaffe n’ebitundu ebitwetoolodde (the `retroperitoneum`) nabyo bisobola okwonooneka olw’obutoffaali buno obuyitibwa histiocytes. Kino kiyinza okuvaako embeera nga:

• Okuzimba kw’ekibumba.
• Okukendeera kw’ekibumba.
• Okulemererwa kw’ekibumba.

Enkola y’enkola y’endwadde z’omubiri (endocrine system) .

Singa histiocytes zino zoonoona endwadde ezikola obusimu obufuga enkola ez’enjawulo mu mubiri gwaffe, ebizibu by’obusimu eby’enjawulo bisobola okuvaamu. Obubonero bwawukana okusinziira ku nseke eyonoonese.

• Singa enseke y’omubiri eyonoonese: Okukendeera kw’okukola obusimu obumu oba ebisingawo (`hypopituitarism`).
• Singa endwadde ya thyroid eyonoonese: Okukendeera kw’obusimu bwa thyroid (hypothyroidism).
• Singa ebitundu by’omubiri ebiyitibwa gonads byonoonese: Okukendeera kw’obusimu bw’okwegatta (nga testosterone ne estrogen) (`hypogonadism`).
• Singa endwadde y’ekibumba eyonoonese: Okukendeera kw’obusimu bw’ekibumba (adrenal insufficiency).

Okwonooneka kw’endwadde z’omubiri (pituitary gland) kuyinza okuvaako embeera eyitibwa diabetes insipidus , ekivaako obubonero ng’okufulumya omusulo ennyo n’okulumwa ennyonta esukkiridde. Kizuuliddwa nti nga kitundu ku balwadde ba ECD nabo balina embeera eno.

Ebikosa enkola y’obusimu

Obwongo bwaffe n’obusimu nabyo bisobola okwonooneka olw’obutoffaali buno obuyitibwa histiocytes. Olwo oyinza okulaba obubonero nga:

• Okubulwa bbalansi ng’otambula, obuzibu mu kukwatagana (ataxia).
• Okwogera okutambula obubi (dysarthria) olw’obutasobola kufuga binywa nga oyogera.
• Okukaluubirirwa okulowooza, okussa ebirowoozo byo oba okujjukira.
• Okulumizibwa omutwe.

Effect ku maaso

ECD esobola okukosa eriiso erimu oba gombi.

• Ebizimba ebya kyenvu ebigonvu ku bikoola by’amaaso (xanthelasma).
• Okufuluma kw’ebikowe by’amaaso (proptosis).
• Okulumwa amaaso.
• Okukendeera oba okubulwa okulaba.

Ebikosa enkola y’okussa

Wadde nga sikaani ziraga nti amawuggwe gakosebwa obuwuka buno obuyitibwa histiocytes, obubonero butera obutabaawo . Kyokka singa obubonero bubaawo, buyinza okuli:

• Okukolola.
• Obuzibu mu kussa (dyspnea).

If not treated properly , kiyinza okuvaako enkovu ez’olubeerera mu mawuggwe (pulmonary fibrosis), embeera ey’amaanyi.

Ebikosa enkola y’emisuwa gy’omutima

Omusawo wo ayinza n’okulaba ku sikaani nti obutoffaali obuyitibwa histiocytes bukosezza omutima gwo n’emisuwa gyo. Kino kiyinza okutta omuntu singa tekijjanjabwa. ECD esobola okuleeta bino wammanga:

• Okuzimba kw’ensawo okwetoloola omutima (pericardial effusion).
• Puleesa (renal hypertension) ebaawo olw’omusaayi obutatambula bulungi mu nsigo.
• Omutima okulemererwa.

Effect ku lususu

Akabonero akasinga okulabibwa ku lususu bwe buzimba obwa kyenvu (`xanthelasma`) obulabika ku bikoola by’amaaso. Okugatta ku ekyo, ebizimba ebya kyenvu-kitaka nabyo osobola okubiraba mu bifo bino:

• Ku maaso.
• Ku bulago.
• Ekifuba n'olubuto (`Torso`).
• Mu kitundu ky’ekisambi.

Okugatta ku ekyo, obusimu buno obusukkiridde busobola okukuŋŋaanyizibwa ne bwonoona ebitundu by’omubiri mu bifo ng’ennywanto, ekibumba n’obusigo bw’amagumba.

Biki ebivaako obulwadde buno?

Kati tukimanyi nti ECD bulwadde nga histiocytes zeeyongera mu ngeri etafugibwa, ne zisaasaana, ne zoonoona ebitundu n’ebitundu ebiramu. Kyokka, bannassaayansi n’okutuusa kati tebamanyi bulungi nsonga lwaki obutoffaali buno bukula nga tebufugibwa. Kyokka, okunoonyereza okwakakolebwa kulaga nti enkyukakyuka ezimu ez’obuzaale zikola kinene.

Abantu abasoba mu kitundu abalina obulwadde bwa Erdheim-Chester (ECD) bazuuliddwa nga balina enkyukakyuka mu ggiini ya BRAF, ekivaako obusimu obuyitibwa histiocytes okukula mu ngeri etafugibwa.

Wadde ng’obuzaale bwa BRAF bwe businga okukyukakyuka, bannassaayansi bazudde enkyukakyuka endala eziwerako mu buzaale ezikwatagana ne ECD. Ebintu bino bye bazudde bisobozesezza bannassaayansi okukola obujjanjabi obugenderera obuzaale obwo obukyusiddwa ne bukomya okukula okutali kwa bulijjo okw’obutoffaali obuyitibwa histiocytes.

Obulwadde buno buzuulibwa butya?

Olw’okuba ECD bulwadde obutatera kulabika nnyo era obubonero bwawukana okusinziira ku muntu, abasawo bayinza obutateebereza mangu mbeera eno. N’olwekyo, kiyinza okutwala ekiseera okusobola okuzuula obulwadde . Oyinza okwetaaga okulaba abasawo abawerako.

Omusawo ajja kulowooza ku bubonero bwo wamu n’ebyava mu kukeberebwa okulala okuwerako okuzuula oba olina ECD. Bino wammanga bye bimu ku bintu ebiyinza okukuyamba okuzuula obulwadde:

• Enkola z’okukuba ebifaananyi: Sikaani ez’enjawulo (X-rays, bone scans, PET scans, CT scans, MRIs) zisobola okukozesebwa okulaba mu mubiri histiocytes zino we ziyingidde mu bitundu by’omubiri. Era zisobola okulaga okwonooneka kw’ebitundu ebigonvu ng’obwongo, ekifuba, n’ebitundu by’olubuto.
• Okukebera mu laboratory:Ebigezo bino bisobola okuzuula ebizibu ebimu ebikwata ku nkola y’ebitundu by’omubiri (ebiyinza okuba nga byekuusa ku ECD), wamu n’okukebera ebintu ng’okuzimba, obutali bwa bulijjo mu bungi bw’obutoffaali bw’omusaayi, n’enkyukakyuka mu busimu.
• Okukebera ebitundu by’omubiri: Okukebera ebitundu by’omubiri (biopsy) kizingiramu okutwala akatundu akatono ak’ebitundu ebikoseddwa n’okubikebera nga bakozesa microscope. Olwo obutoffaali buno bukeberebwa okulaba oba temuli bubonero bwa ECD n’enkyukakyuka mu buzaale nga BRAF. Okumanya engeri y’obutoffaali buno kiyinza okuyamba omusawo wo okusalawo obujjanjabi ki obusinga okukuyamba.

Obujjanjabi bwe buruwa?

Bw’oba ​​tolina bubonero era nga ECD yo tekosa bulamu bwo, omusawo ayinza okusalawo okulondoola embeera yo. Kyokka, abantu abasinga obungi abalina ECD bajja kwetaaga obujjanjabi . Wadde nga tewali ddagala, waliwo obujjanjabi obuwerako obuyinza okuyamba okuddukanya embeera eno.

Zino ze nkola enkulu ez’obujjanjabi:

• Obujjanjabi obugendereddwamu: Kino kizingiramu okukozesa eddagala erigenderera enkyukakyuka mu buzaale ezireetera obusimu obuyitibwa histiocytes okweyongera mu ngeri etafugibwa. Ekitongole kya FDA kikkirizza eddagala eriyitibwa Vemurafenib eri abalwadde ba ECD abalina enkyukakyuka mu buzaale bwa BRAF, n’eddagala eriyitibwa Cobimetinib eri abo abalina enkyukakyuka mu buzaale bwa MEK. Okusinziira ku kika ky’enkyukakyuka mu butoffaali bwo, omusawo ayinza okukuwa amagezi ku ddagala lino oba eddala erigendereddwamu oba eddagala erigatta.
• Obujjanjabi bw’abaserikale b’omubiri: Eddagala lino liyamba abaserikale baffe abaserikale okutegeera obulungi n’okulwanyisa obutoffaali bwa kookolo (mu mbeera eno, histiocytes ezitali za bulijjo). Interferon-alpha ddagala eritera okukozesebwa mu kujjanjaba obusimu obuziyiza endwadde ku ECD.
• Chemotherapy: Chemotherapy ekozesa eddagala okutta obutoffaali bwa kookolo (abnormal cells) mu mubiri gwonna n’okukomya okukula kw’ebizimba. Eddagala erisinga okukozesebwa ku ECD ye cladribine . Kyokka omusawo ayinza okukuwa amagezi okukozesa eddagala eddala erijjanjaba eddagala oba eddagala erigatta.

Ng’oggyeeko obujjanjabi buno obukulu, omusawo ayinza okukuwa amagezi ku bujjanjabi obulala okuyamba okumalawo obubonero bwo. Wadde obujjanjabi buno tebujja kulemesa histiocytes kuyingira mu bitundu byo, busobola okuyamba okukendeeza ku buzibu bw’owulira.

• Okulongoosebwa: Kiyinza okwetaagisa okulongoosebwa okuddaabiriza ebimu ku bitundu by’omubiri ebyonooneddwa olw’ECD. Okugeza okuzimba n’ebitundu ebyonooneddwa bisobola okuziba emisuwa egitambuza omusulo (ureters). Kino bwe kibaawo, kiyinza okwetaagisa okulongoosebwa okukiddaabiriza.
• Obujjanjabi bw’amasannyalaze (radiation therapy):Obujjanjabi bw’amasannyalaze buyinza okulagirwa okusaanyaawo obutoffaali obutali bwa bulijjo mu kitundu ekimu eky’omubiri n’okukendeeza ku bubonero obutanyuma bwe buleeta.
• Corticosteroids: Eddagala lino liyinza okukendeeza ku buzimba obuva ku kuyingira kw’obutoffaali obuyitibwa histiocytes.

Oyinza n'okufuna omukisa okwetaba mu kugezesebwa okw'obujjanjabi . Okugezesebwa mu malwaliro kwe kunoonyereza okugezesa obukuumi n’obulungi bw’obujjanjabi obupya n’obujjanjabi obupya obugatta. Buuza omusawo wo oba osobola okwetaba mu kugezesebwa okw’obujjanjabi ku bulwadde bwa Erdheim-Chester (ECD).

Kino kisobola okuziyizibwa?

Ebyembi, tewali ngeri yonna gye tuyinza kuziyiza bulwadde bwa Erdheim-Chester (ECD). Wabula obulwadde buno okusinga busobola okubujjanjabwa n’obujjanjabi.

Osobola okuwangaala n’obulwadde buno okumala bbanga ki?

Enteebereza yo esinziira ku bitundu by’omubiri gwo ebikoseddwa histiocytes n’engeri gy’okwatamu obujjanjabi. Naye, olw’okukola obujjanjabi obupya, gamba ng’obujjanjabi obugendereddwamu, ebiva mu bulamu ebikwatagana ne ECD kati biteredde nnyo.

Teebereza, mu 1996, omuwendo gw’okuwangaala kw’emyaka etaano eri abalwadde ba ECD gwali 43% zokka. Kyokka okusinziira ku kunoonyereza okwakakolebwa, omuwendo ogwo gweyongedde okutuuka ku bitundu 83%!

Yogerako n’omusawo wo ku ngeri obulwadde bwo gye bugenda okutambulamu mu biseera eby’omu maaso okusinziira ku mbeera yo n’engeri gy’okwatamu obujjanjabi.

Ddi lw’osaanidde okulaba omusawo?

ECD yeetaaga obujjanjabi n'okulondoola okugenda mu maaso . Omusawo ajja kukuwa amagezi ku mirundi gy’olina okulaba omusawo wo, n’okumanya oba olina okukeberebwa sikaani n’okukeberebwa omusaayi.

Obujjanjabi bungi ku ECD busobola okuleeta ebizibu ebitali birungi . Ng’oggyeeko ttiimu yo ey’obujjanjabi bwa ECD, okufuna obuyambi okuva mu ttiimu y’abajjanjabi eriweweeza ku bulwadde buno kiyinza okukuyamba okuddukanya ebizibu ebiva mu bujjanjabi buno n’okugumira situleesi ejja n’okuzuula obulwadde.

N’ekisembayo, ekisinga obukulu (Obubaka bw’okutwala awaka) .

Obulwadde bwa Erdheim-Chester (ECD) mbeera ekosa buli muntu mu ngeri ey’enjawulo, eva ku kukola ennyo kw’obutoffaali obuyitibwa histiocytes, obwonoona ebitundu by’omubiri. Obubonero n’obubonero bw’obulwadde buno bwawukana okusinziira ku muntu. Bino bisobola okukosa obumanyirivu bwo okutwalira awamu, nga mw’otwalidde n’obujjanjabi obuliwo.

Naye, ekirungi, olw’enkulaakulana gye buvuddeko, bannassaayansi basobodde okufuna obujjanjabi obulongoosa okuteebereza kwa ECD.Yogerako mu lwatu n’omusawo wo ku ngeri z’obujjanjabi ezikusaanira n’ebivaamu by’oyinza okusuubira, okusinziira ku ngeri entongole ez’embeera yo. Jjukira nti ne mu mbeera eno etali ya bulijjo, osobola okugenda mu maaso n’amaanyi ng’olina amagezi n’obuwagizi obutuufu obw’abasawo.

` Obulwadde bwa Erdheim-Chester, ECD, histiocytosis, endwadde ezitatera kulabika, enkyukakyuka mu buzaale, BRAF, obubonero, obujjanjabi
