Hemoglobin (Hb) ndi metalloprotein yovuta yokhala ndi chitsulo yomwe imakhala mkati mwa maselo ofiira a m'magazi. Ntchito yake yayikulu ya thupi—kumanga mpweya wosinthika ndi kunyamula kuchokera ku alveoli ya m'mapapo kupita ku minofu yozungulira, pamodzi ndi kubweza kwa carbon dioxide—imapangitsa kuti ikhale yofunika kwambiri pa kupuma kwa maselo ndi kagayidwe kachakudya. Chifukwa chake, kuyeza kuchuluka kwa hemoglobin m'ma laboratories ndi chimodzi mwa mayeso ofunikira kwambiri komanso oyambira azachipatala. Kufunika kwake kumapitirira patali kuzindikira kuchepa kwa magazi m'thupi; imagwira ntchito ngati chida chofunikira chowunikira, kampasi yowunikira yosiyana, chizindikiro cholosera matenda osatha, komanso chinthu chofunikira popanga zisankho mu chisamaliro cha odwala omwe ali ndi khansa komanso opaleshoni.

Kuwunika Koyamba ndi Kuzindikira Matenda

Kufunika kwakukulu kwa mayeso a hemoglobin kuli mu mphamvu yake yeniyeni yoyezera mphamvu yonyamula mpweya m'magazi. Kupatuka kuchokera ku magawo odziwika bwino—nthawi zambiri 130–175 g/L kwa amuna akuluakulu ndi 115–150 g/L kwa akazi omwe si apakati—kumakhala ngati chizindikiro choyamba cha matenda awiri osiyana kwambiri. Kuchuluka kwa magazi pansi pa malire otsika kumatanthauza kuchepa kwa magazi m'thupi, vuto lomwe limadziwika ndi kuchepa kwa magazi m'thupi komwe kumaonekera m'thupi monga kutopa, khungu lotuwa, kupuma movutikira, ndi kulephera kuzindikira. Pa milandu yoopsa (Hb <70 g/L), kuchepa kwa magazi m'thupi kumeneku kumaika vuto lalikulu pa dongosolo la mtima, zomwe zingayambitse kulephera kwa mtima. Mosiyana ndi zimenezi, kuchuluka kwa magazi m'thupi kopitirira malire apamwamba kumasonyeza erythrocytosis, yomwe imakweza kukhuthala kwa magazi ndikuwonjezera kwambiri chiopsezo cha thromboembolic, zomwe zimapangitsa odwala kukhala ndi ngozi za mitsempha yamagazi komanso thrombosis ya mitsempha yamagazi.

Kuzindikira Kusiyanasiyana Pogwiritsa Ntchito Zizindikiro za Erythrocyte

Ngakhale kuti hemoglobin yeniyeni imasonyeza kuti pali vuto, mphamvu yake yeniyeni yodziwira matenda imatulutsidwa ikamasuliridwa limodzi ndi zizindikiro za maselo ofiira a magazi—makamaka, Mean Corpuscular Volume (MCV) ndi Mean Corpuscular Hemoglobin (MCH). Kugawika kwa kagayidwe kameneka ndi maziko a kafukufuku wa etiological. Microcytic hypochromic profile (low MCV ndi MCH) imasonyeza kwambiri kusowa kwa iron, komwe nthawi zambiri kumachokera ku kutuluka magazi m'mimba kosalekeza kapena menorrhagia, kapena, kumasonyeza khalidwe la thalassemia kapena kuchepa kwa magazi m'thupi la matenda osatha. Kusiyana kumeneku n'kofunika kwambiri pa chithandizo, chifukwa kuwonjezera iron mwa odwala a thalassemia kungayambitse kuchulukira kwa iron m'thupi. Macrocytic profile (MCV yokwezeka) imayambitsa kukayikira kwachipatala za cobalamin (vitamini B12) kapena kusowa kwa folate, komwe kumalumikizidwa ndi zotsatira za mitsempha, kapena ku matenda a myelodysplastic. Kachitidwe ka normocytic nthawi zambiri kamayambitsa kufufuzidwa kwa kutuluka magazi mwachangu, hemolysis, kapena kulephera kwa mafupa. Motero, kuyezetsa hemoglobin, pamodzi ndi zizindikiro, kumathandiza kuchepetsa kusiyana kwakukulu mu njira yodziwira matenda.

Chizindikiro cha Alonda cha Matenda Osatha a Thupi

Kupatula matenda oyamba a magazi, kuyang'anira hemoglobin mwatsatanetsatane kumagwira ntchito ngati mlonda wosamala pakukula kwa matenda osiyanasiyana osatha a m'thupi. Mu matenda osatha a impso (CKD), renal interstitium yolephera imapanga erythropoietin (EPO) yosakwanira, zomwe zimapangitsa kuti pakhale kuchepa kwa magazi m'thupi. Kuchuluka kwa hemoglobin m'magazi kumagwirizana mwachindunji ndi kuwonongeka kwa ntchito ya impso ndipo kumalamulira chisankho chachipatala choyambitsa chithandizo cholowa m'malo mwa EPO. Mu oncology, hemoglobin yosafotokozedwa bwino, yopita patsogolo imatsika mwa wodwala wodwala matenda a febrile nthawi zambiri imasonyeza kulowa kwa mafupa chifukwa cha metastases kapena kuyimira zotsatira za paraneoplastic za ma cytokines osatha otupa. Kuphatikiza apo, mwa odwala omwe akulandira myelosuppressive chemotherapy kapena radiotherapy, hemoglobin nadir ndi chizindikiro chofunikira chomwe madokotala a oncologists amagwiritsa ntchito kuti adziwe kusintha kwa mlingo, kufunikira kwa chithandizo chowonjezera magazi, kapena kufunikira kwa kusokoneza chithandizo.

Kugawa Ziwopsezo ndi Kuwunika Mankhwala

Mu nthawi ya opaleshoni, kuyezetsa hemoglobin musanachite opaleshoni sikungatheke. Kumagwira ntchito ngati chizindikiro champhamvu cha matenda ochitidwa opaleshoni; odwala omwe ali ndi kuchepa kwa magazi m'thupi asanachite opaleshoni amakhala ndi matenda ambiri pambuyo pa opaleshoni, kuchira kwa bala mochedwa, komanso kukhala kuchipatala kwa nthawi yayitali. Magulu opanga opaleshoni nthawi zambiri amagwiritsa ntchito choyambitsa magazi (nthawi zambiri Hb < 70-80 g/L mwa odwala okhazikika) kuti azitha kupereka mpweya wabwino asanayambe opaleshoni. Kuphatikiza apo, hemoglobin ndiye muyezo wagolide wowunikira momwe chithandizo chimagwirira ntchito. Mwachitsanzo, mu kuchepa kwa magazi m'thupi komwe kulibe chitsulo, kuwonjezeka koyezedwa kwa osachepera 10-20 g/L mu Hb mkati mwa milungu iwiri kapena inayi kuchokera pakumwa chithandizo cha chitsulo kumapereka umboni wotsimikizika wa kuyamwa kwa m'mimba ndi momwe mafupa amayankhira. Kusowa kwake kumayambitsa kuwunikanso nthawi yomweyo kwa matenda kapena kufufuza kuti palibe kutsatira.

Pomaliza, kuyezetsa hemoglobin sikuti ndi chizindikiro cha magazi wamba; ndi chizindikiro chofunikira kwambiri, chokhala ndi mbali zambiri chomwe chimagwirizanitsa kagwiridwe ka mpweya ndi chidziwitso cha matenda. Kuwunika kwake nthawi zonse kumathandiza kuchenjeza msanga, kugawa molondola matenda, kutsata matenda osatha, komanso kuyang'anira matenda mosamala komanso motsatira umboni m'madokotala onse.
