IVithamin C, ekwabizwa ngokuba yi-ascorbic acid, sisondlo esinyibilikayo emanzini. Abantu kunye nezinye izilwanyana (ezifana neeprimates, iihagu) zixhomekeke kwi-vitamin C kwisondlo seziqhamo kunye nemifuno (ipepile ebomvu, i-orenji, i-strawberry, i-broccoli, imango, i-lemon). Indima enokubakho ye-vitamin C ekukhuseleni nasekuphuculeni usulelo luye lwaqatshelwa kuluntu lwezonyango.
I-Ascorbic acid ibalulekile ekuphenduleni komzimba. Inomsebenzi obalulekileyo wokulwa nokuvuvukala, i-immunomodulatory, i-antioxidant, i-anti-thrombosis kunye ne-anti-viral properties.
I-Vitamin C ibonakala ikwazi ukulawula impendulo yomninimzi kwi-acute acute breathing syndrome ye-coronavirus 2 (SARS-CoV-2). ICoronavirus ngunobangela wobhubhani we-coronavirus ka-2019 (i-COVID-19), ngakumbi Ikwixesha elinzima. Kwingxelo yamva nje epapashwe kwi-Preprints *, uPatrick Holford et al. Isonjululwe indima kavithamin C njengonyango oluncedisayo kusulelo lokuphefumla, i-sepsis kunye ne-COVID-19.
Eli nqaku lixoxa ngendima enokubakho ye-vitamin C ekuthinteleni inqanaba elibalulekileyo le-COVID-19, usulelo oluqatha lokuphefumla kunye nezinye izifo ezivuthayo. Ukongezwa kweVithamin C kulindeleke ukuba ibe sisixhobo sothintelo okanye sonyango kwi-COVID-19-ukusilela okubangelwa sesi sifo, ukunciphisa uxinzelelo lwe-oxidative, ukomeleza imveliso ye-interferon kunye nokuxhasa iziphumo zokuchasa ukudumba kweglucocorticoids.
Ukuze kugcinwe amanqanaba eplasma aqhelekileyo kubantu abadala kwi-50 µmol/l, idosi ye-vitamin C yamadoda yi-90 mg/d kunye nabasetyhini i-80 mg/d. Oku kwanele ukukhusela i-scurvy (isifo esibangelwa ukungabikho kwe-vitamin C). Nangona kunjalo, eli nqanaba alanelanga ukukhusela ukuvezwa kwentsholongwane kunye noxinzelelo lomzimba.
Ngoko ke, i-Swiss Nutrition Society incoma ukuncedisa umntu ngamnye nge-200 mg ye-vitamin C-ukugcwalisa i-gap yesondlo sabantu bonke, ngakumbi abantu abadala be-65 iminyaka nangaphezulu. Esi songezo senzelwe ukomeleza amajoni omzimba. "
Ngaphantsi kweemeko zoxinzelelo lwe-physiological, amanqanaba e-serum ye-vitamin C ehla ngokukhawuleza. Isiqulatho se-serum yevithamin C kwizigulana ezilaliswe esibhedlele ngu-≤11µmol/l, kwaye uninzi lwabo luthwaxwa lusulelo olubukhali lokuphefumla, i-sepsis okanye i-COVID-19 eqatha.
Izifundo ezahlukeneyo ezivela kwihlabathi liphela zibonisa ukuba amanqanaba asezantsi evithamin C aqhelekile kwizigulana ezigula kakhulu ezinosulelo lokuphefumla, inyumoniya, i-sepsis kunye ne-COVID-19-eyona nkcazo inokwenzeka kukwanda kokusetyenziswa kwe-metabolic.
Uhlalutyo lwemeta luqaqambise oku kulandelayo: 1) Ukongezwa kweVithamin C kunokunciphisa kakhulu umngcipheko wenyumoniya, 2) Uphando lwasemva kobhubhani emva kokubhubha kwe-COVID-19 lubonise inyumoniya yesibini, kwaye 3) Ukunqongophala kweVithamin C kubalele kubo bonke abantu abanale ngxaki. inyumoniya 62%.
I-Vitamin C inesiphumo esibalulekileyo se-homeostatic njenge-antioxidant. Kuyaziwa ukuba inomsebenzi wokubulala intsholongwane ngokuthe ngqo kwaye inokunyusa imveliso ye-interferon. Ineendlela ezisebenzayo kuzo zombini izixokelelwano zokuzikhusela ezizalwa kunye neziguquguqukayo. I-Vitamin C inciphisa iintlobo ze-oksijeni ezisebenzayo (ROS) kunye nokuvuvukala ngokunciphisa ukusebenza kwe-NF-κB.
I-SARS-CoV-2 phantsi-ilawula ukubonakaliswa kohlobo loku-1 lwe-interferon (eyona ndlela yokukhusela i-antiviral ye-antiviral), ngelixa i-ascorbic acid iphakamisa-ilawula ezi proteni zingundoqo zokukhusela.
Inqanaba elibalulekileyo le-COVID-19 (elihlala linqanaba elibulalayo) lenzeka ngexesha lokuveliswa ngokugqithisileyo kweecytokines kunye neekhemokines ezisebenza ngokusukileyo. Oku kwakhokelela ekuphuhlisweni kokusilela kwamalungu amaninzi. Inxulumene nokufuduka kunye nokuqokelelwa kwe-neutrophils kwi-lung interstitium kunye ne-bronchoalveolar cavity, le yokugqibela ibe yinto ephambili yokumisela i-ARDS (i-Acute Respiratory Distress Syndrome).
I-concentration ye-ascorbic acid kwi-adrenal glands kunye ne-pituitary gland iphindwe kathathu ukuya kwishumi eliphezulu kunalo naliphi na ilungu. Ngaphantsi koxinzelelo lwe-physiological (ACTH stimulation) iimeko ezibandakanya ukuvezwa kwentsholongwane, i-vitamin C ikhutshwa kwi-adrenal cortex, ebangela ukuba amanqanaba e-plasma anyuke ngokuphindwe kahlanu.
I-Vitamin C inokunyusa ukuveliswa kwe-cortisol, kwaye iphucule i-anti-inflammatory kunye ne-endothelial cell effect ekhuselayo ye-glucocorticoids. I-Exogenous glucocorticoid steroids kuphela kweziyobisi ezithe zangqina ukunyanga i-COVID-19. I-Vitamin C i-multi-effect stimulating hormone, edlala indima ebalulekileyo ekulungelelaniseni impendulo yoxinzelelo lwe-adrenal cortex (ingakumbi i-sepsis) kunye nokukhusela i-endothelium kumonakalo we-oxidative.
Ukuthathela ingqalelo ifuthe levithamin C kwingqele-ukunciphisa ixesha, ubungqongqo kunye nokuphindaphinda kokuthatha ivithamin C ebandayo kunokunciphisa utshintsho ukusuka kusulelo olungephi ukuya kwixesha elibalulekileyo le-COVID-19.
Kuye kwaphawulwa ukuba ukongezwa kwevithamin C kunokunciphisa ubude bokuhlala kwi-ICU, kucuthe ixesha lokungena umoya kwizigulana ezigula kakhulu nge-COVID-19, kunye nokunciphisa izinga lokusweleka kwezigulana ze-sepsis ezifuna unyango nge-vasopressors.
Ukuqwalasela iimeko ezahlukeneyo zohudo, amatye entso kunye nokungaphumeleli kwezintso ngexesha eliphezulu, ababhali baxubusha ukhuseleko lomlomo kunye nokulawulwa kwe-intravenous ye-vitamin C. I-dose ekhuselekileyo yexesha elifutshane le-2-8 g / ngosuku inokunconywa ( ngononophelo uphephe iidosi eziphezulu kubantu abanembali yamatye ezintso okanye isifo sezintso). Ngenxa yokuba i-soluble yamanzi, inokukhutshwa kwiiyure ezimbalwa, ngoko ke i-dosage frequency ibalulekile ukugcina amanqanaba aneleyo egazi ngexesha losulelo olusebenzayo.
Njengoko sonke siyazi, i-vitamin C inokuthintela usulelo kwaye iphucule impendulo yomzimba. Ngokukodwa ngokubhekisele kwinqanaba elibalulekileyo le-COVID-19, ivithamin C idlala indima ebalulekileyo. Iphantsi-ilawula isivunguvungu se-cytokine, ikhusela i-endothelium kumonakalo we-oxidative, idlala indima ebalulekileyo ekulungiseni izicubu, kwaye iphucula impendulo yokuzivikela kwintsholongwane.
Umbhali ucebisa ukuba izongezo ze-vitamin C kufuneka zongezwe yonke imihla ukukhuthaza amaqela asemngciphekweni omkhulu wokusweleka kwe-COVID-19 kunye nokunqongophala kwevithamin C. Kufuneka bahlale beqinisekisa ukuba i-vitamin C yanele kwaye inyuse umthamo xa intsholongwane isuleleke, ukuya kwi-6-8 g / ngosuku. Inani lezifundo ezixhomekeke kumthamo wevithamin C ezixhomekeke kwidosi ziyaqhuba kwihlabathi liphela ukuqinisekisa indima yazo ekudambiseni i-COVID-19 kunye nokuqonda ngcono indima yayo njengento enokubakhona kunyango.
Iipreprints ziya kupapasha iingxelo zokuqala zenzululwazi ezingakhange zihlolwe ngoontanga, kwaye ngoko ke akufanele zithathwe njengento ecacileyo, ekhokelayo yokusebenza kweklinikhi / ukuziphatha okunxulumene nempilo okanye kuthathelwe ingqalelo ulwazi olucacileyo.
