Kuongororwa kwe sickle cell anemia
Tsanangudzo ye sickle cell anemia
La sickle cell anemia, Inonziwo sickle cell anemia, chirwere cheropa chinogarwa nhaka (kunyanya hemoglobin) inova chirwere chemajini chinowanzoitika muFrance neQuebec.
Ile-de-France ndiyo dunhu rakakanganisika zvakanyanya (kunze kweDOM-TOM) ine vanenge 1/700 vachangozvarwa vakabatwa. Pakazara, muFrance, vanhu vangangosvika gumi vanofungidzirwa kuti vari kurwara nechirwere chegomarara.
Chirwere ichi chinonyanya kubata vanhu vanobva kuMediterranean, Africa neCaribbean. Zvinofungidzirwa kuti vacheche vanosvika mazana matatu negumi nevaviri vanozvarwa vari kubatwa pasi rose, zvikuru muSouth Africa.
Sei vachangobva kuberekwa vachiongororwa chirwere chekushaya ropa?
Pakarepo chirwere ichi chinoonekwa, zviri nani kutarisirwa uye mikana yekurarama kwemwana.
MuFrance, a kuongororwa achangoberekwa saka inopihwa zvakarongeka kuvacheche vane vabereki vanobva kunzvimbo dziri panjodzi. Inoitwa muvana vese vachangozvarwa mumadhipatimendi ekumhiri kwemakungwa.
MuQuebec, kuongorora hakuna kurongeka kana kungoitawo zvawo: kubva muna Mbudzi 2013, vacheche vanoberekerwa muzvipatara nenzvimbo dzekuberekera muMontreal neLaval vanongokwanisa kuwana bvunzo yekuongorora sickle cell anemia.
Ndezvipi zvatingatarisira kubva mukuongororwa kwe sickle cell anemia?
Muedzo we chomukondombera inovavarira kuratidza kuvepo kwe masero matsvuku eropa asina kujairika maitiro echirwere, akaumbwa se "jeko". Zvakare kunzi jeko, vane chimiro chakareba chinogona kuonekwa pasi pemaikorosikopu (neropa smear). Izvo zvakare zvinokwanisika kuita genetic test kuti uone mutated gene.
Mukuita, kuongorora kuchangoberekwa kunobva pakuongorora hemoglobin ne electrophoresis, nzira yekuongorora iyo inogona kuona kuvapo kwehemoglobin isina kujairika, iyo "inofamba" zvishoma nezvishoma kupfuura hemoglobin yakajairika kana ichiendeswa kune imwe nzvimbo inokosha.
Iyi nzira inogona kuitwa paropa rakaomeswa, izvo zvinoitika panguva yekuongororwa kwevachangozvarwa.
Muedzo unoitwa sechikamu chekuongororwa kwezvirwere zvakasiyana zvisingawanzo pa72st awa yehupenyu muvana vachangoberekwa, kubva mumuenzaniso weropa wakatorwa nekubaya chitsitsinho. Hapana kugadzirira kunodiwa.
Ndedzipi mhedzisiro dzatingatarisire kubva pakuzvarwa patsva kuongororwa kwechirwere chesickle cell?
Mhedzisiro yebvunzo imwe chete haina kukwana kusimbisa kuongororwa. Kana pasina mubvunzo, vabereki vemwana achangoberekwa vachabatwa uye mimwe miedzo ichaitwa kusimbisa kuongororwa uye kuronga kurapwa.
Mukuwedzera, kuedza kunoita kuti zvikwanise kuona vana vanotambura nechirwere, asiwo vana vasina kukanganiswa asi vakatakura mutated gene. Vana ava havazorwari, asi vanenge vari panjodzi yekupfuudza chirwere ichi kuvana vavo. Ivo vanonzi "vatakuri vane hutano" kana kuti heterozygotes yejene cell gene.
Vabereki vanozoziviswawo nezvenyaya yekuti kune njodzi yechirwere kune vamwe vana vavo, uye genetic follow up ichapihwa kwavari.
