I-Hypercalcemic Crisis of Malignancy noma i-Hyperparathyroidism: Amathambo, Amatshe, Ukugquma, Ukudlula Kwengqondo, kanye ne-Aggressive Saline-Calcitonin¶

I-hypercalcemic crisis (i-hypercalcemia enezimpawu ezinzima) iyisimo esiphuthumayo se-endocrine kanye ne-oncological esisongela ukuphila esichazwa yi-albumin-corrected total serum calcium ngenhla 14.0 mg/dL (3.50 mmol/L), noma i-ionized serum calcium engaphezu kuka-10.0 mg/dL (2.50 mg/dL (2.50 multi-mlorgan) noma iyiphi i-dyscue multi-mol/L i-calcium engaphezu kuka-12.0 mg/dL (3.00 mmol/L) yethula ngokuwohloka okukhulu kwemizwa, inhliziyo, noma izinso. Ngaphezu*** kwamaphesenti angu-90 azo zonke izinkinga ze-hypercalcemic** aqhutshwa yizimbangela ezimbili nje eziyisisekelo: I-Hypercalcemia of Malignancy (ethinta kufika kumaphesenti angu-20 kuya kwangu-30 eziguli ezinomdlavuza, ngokuvamile i-squamous cell lung, ikhanda-ne-neck, noma umdlavuza we-esophageal, renal cell carcinoma, umdlavuza webele, i-multiple myeloma, i-lymphoma ye-lymph, i-lymph nodes I-Hyperparathyroidism Eyinhloko (Inkinga Ye-Parathyroid) evela ku-hyperfunctioning parathyroid adenoma noma i-carcinoma. Odokotela baqaphela i-classic multi-system syndrome nge-mnemonic "Amathambo, Amatshe, I-Abdominal Groans, Ne-Psychiatric Moans (Overtones)": amathambo (i-osteolytic bone pain and pathologic fractures), stones (i-calcium kidney stones kanye ne-calcium-induced nephrogenic diabetes insipidus, okubangela ukuqina kwezinso i-polyuria engapheli yamalitha angu-4 kuye kwayi-8 ngosuku kanye ne-4-to-6-litre ejulile ye-intravascular dehydration), ukububula kwesisu (isicanucanu esingalawuleki, ukuhlanza, ukuqunjelwa okukhulu, izilonda ze-peptic, kanye acute hypercalcemic pancreatitis), kanye *ne-psychiatric overtones, i-leukemia, ukudideka, ukudideka kanye nekoma), eceleni izikhawu ezifinyeziwe ze-QTc, amagagasi e-Osborn J, i-bradycardia, ukuvimba kwenhliziyo okuphelele, kanye ne-fibrillation ye-ventricular. Uma noma isiphi isiguli esinomdlavuza, isifo se-parathyroid esaziwayo, noma ukudla ngokweqile kwe-vitamin D/calcium siba nokukhathala okukhulu, ukudideka, ukoma okungapheli nokuchama, ukuhlanza okungalawuleki, noma ukushaya kwenhliziyo okunensa/okungajwayelekile, shayela indawo yangakini. izinombolo eziphuthumayo ngokushesha. Futhi buyekeza imihlahlandlela yethu yezelamani ku I-tumor lysis syndrome (TLS) ngemuva kokwelashwa ngamakhemikhali, i-renal colic yezinso kanye nezinso ezithintekile, futhi i-pancreatitis eyingozi, i-gallbladder, kanye ne-cholangitis ekhuphukayo.

Okubalulekile kwakho ngokushesha ukuthutha isiguli esibhedlela Umnyango Wezimo Eziphuthumayo ukuze uthole ngokushesha i-ECG eholayo engu-12 (ukuhlola isikhawu esifushane se-QTc kanye nokuvinjwa kwenhliziyo) kanye ne-Albumin-Corrected + Ionized Calcium blood testing*, qala ngokushesha, okunolaka okufakwe emthanjeni okungu-0.9% okulandelwa yi-Nortation m2000 ilandelwa yi-Nortation m20000000000000 yosus 300 mL/ihora) ukuze uhlehlise ukuphelelwa amanzi emzimbeni okukhulu okubangelwa i-calcium-induced nephrogenic Diabetes insipidus NGAPHAMBI ngisho nokucabangela noma iyiphi i-loop diuretic, futhi enze I-Dual-Speed Pharmacological Rescue: I-Subcutaneous/IM Salmon Calcitonin (4 kuya ku-8 yehla kuya ku-calcium IU/kg emahoreni angu-6 njalo ngamahora angu-6) ngesikhathi esisodwa kubhangqwe ne-Intravenous Zoledronic Acid (4 mg IV phezu kwemizuzu engu-15) noma i-Subcutaneous Denosumab (60 kuya ku-120 mg, ethatha amahora angu-48 kuya kwangu-96 ukukhahlela kodwa inikeza ukulawula okuqhubekayo kwamaviki angu-3 kuya kwayi-4).

Yenza lokhu manje¶

1. Shayela inombolo yakho yasendaweni yezimo eziphuthumayo ngokushesha uma isiguli esinomdlavuza, i-hyperparathyroidism, noma isifo se-granulomatous siba nokudideka, ukozela okukhulu, ukuhlanza okungalawuleki, noma ubuthakathaka obukhulu. Shayela u-911 e-United States nase-Canada, 999 e-United Kingdom, 112 yonkana i-European Union, 000 e-Australia, noma uthintane nencwadi yethu yemibhalo izinombolo eziphuthumayo. I-hypercalcemia enzima ithuthuka ngokushesha isuka ebuthakathakeni kanye nenkulumo engahlangani iye kwikhoma, ukwehluleka kwezinso okukhulu, kanye nokuboshwa kwenhliziyo okungazelelwe kwe-bradycardic/ventricular.
2. Yeka ngokushesha yonke imithi ekhulisa i-calcium nezithasiselo ekhaya nasesibhedlela:
3. Misa zonke izithako ze-calcium ngomlomo, ama-calcium carbonate antacids (Tums, Rennie, Rolaids), kanye nezithako ze-Vitamin D / calcitriol.
4. Misa Izidakamizwa ze-Thiazide diuretics (hydrochlorothiazide, chlorthalidone, indapamide, metolazone), eziphoqa ishubhu elikude le-renal ukuthi limunce kabusha i-calcium egazini.
5. Misa I-Lithium (enyakazisa i-parathyroid calcium-sensing receptor setpoint phezulu) kanye ne-Digoxin (i-hypercalcemia enzima izwela imisipha yenhliziyo ukuba i-digoxin, ibangele ukufa **i-digoxin-induced ventricular arrhythmias kanye nenhliziyo ephelele **).
6. Uma isiguli siphapheme ngokuphelele, siqaphile, futhi singahlanzi, khuthaza ukuthi siphuze amanzi alula endleleni eya esibhedlela; uma usozela, udidekile, noma uhlanza, gcina i-Nothing by Mouth (NPO) futhi ubeke endaweni yokululama ngemuva. Sonke isiguli esisenkingeni ye-hypercalcemic siphelelwa amanzi emzimbeni ngamalitha angu-4 kuya kwangu-6 okulahlekelwa amanzi, kodwa iziguli ezozelayo zingafuna kalula uketshezi lomlomo.
7. Qinisekisa ukuthi Odokotela Basesibhedlela Babala I-Albumin-Corrected Calcium (noma Measure Direct Ionized Calcium) Futhi Bathola I-ECG Ehola 12 Ngokushesha. Ngoba iziguli ezinomdlavuza cishe zihlala zine-serum albumin ephansi (hypoalbuminemia), isamba "esiphezulu" esingalungisiwe esingalungisiwe sesamba se-calcium engu-\(12/indL nge-albhamu yesiguli esingu-\)12/indL yesiguli esingu-\(12. I-\)2.0\text{ g/dL}$ empeleni ibeka impilo engozini i-Albumin-Corrected Calcium engu-\(13.8\text{ mg/dL}\): $\(\text{I-Calcium Elungisiwe (mg/dL)} = \umbhalo{Ingqikithi Yengqikithi Ye-Ca (mg/dL)} + 0.8 \izikhathi \kwesokunxele(4.0 - \text{Serum Albumin [g/dL]}\kwesokudla)\)$
8. Phikelela Ekungeneni Ngemithambo Okunamandla 0.9% Okujwayelekile Kasawoti Wamanzi (200 kuya ku-300 mL/ngehora) OKOKUQALA, FUTHI UNGALOKOTHI Unikeze I-IV Furosemide (Lasix) Kuze Kube Ukuncipha Kwevolumu Kubuyiselwe Ngokugcwele. Iphutha elisabalele, eliyingozi ukujova i-IV furosemide ngokushesha nje lapho i-calcium ephezulu ibonakala kumalebhu. Ukunikeza i-loop diuretic esigulini esine-hypercalcemic enevolomu enciphile kwenza ukuphelelwa amanzi emzimbeni kubi, kwehlisa izinga lokuhlunga kwe-glomerular (GFR), futhi kwenyusa ukumuncwa kabusha kwe-calcium ye-tubular, kuqhubekisela phambili i-calcium yegazi ngaphezulu. Ama-Loop diuretics asetshenziswa kuphela ngemva kokuba amalitha kasawoti ojwayelekile esebuyisele i-euvolemia futhi kuphela uma kuvela izimpawu zokugcwala koketshezi.
9. Lawula i-Subcutaneous Calcitonin KANYE NE-Intravenous Zoledronic Acid (noma i-Subcutaneous Denosumab Ekuhlulekeni Okubi Kwezinso) Ndawonye Ngaphakathi Ihora Lokuqala. Ngoba i-Zoledronic Acid ne-Denosumab kuthatha izinsuku ezingu-2 kuya kwezingu-4 (amahora angu-48 kuya kwangu-96) ukuqala ukwehlisa igazi le-calcium, inikeze i-bisphonate yokuqala yodwa i-bisphonate eyingozi kakhulu amahora angu-8. Ukunikeza I-Subcutaneous Salmon Calcitonin (\(4\text{ IU/kg}\) njalo ngamahora angu-12) eduze kwamabhuloho e-Zoledronic Acid anegebe lamahora angu-48 ngokwehlisa i-serum calcium ngo-\(1\text{ ukuya }2\text{ mg/dL}\) phakathi kwamahora angu-4 kuya kwangu-6*.

Izimpawu zomtholampilo ze-Multi-system kanye nezimpawu ze-ECG ze-hypercalcemic crisis¶

1. Isistimu Yezitho Ezine ("Amathambo, Amatshe, Ukugquma, kanye Nezimo Zengqondo")¶

1. I-Neurological & Neuromuscular ("I-Psychiatric Overtones"): Ngenxa yokuthi i-calcium ephezulu ye-extracellular iphakamisa i-threshold voltage edingekayo ukuze kushiswe amashaneli e-sodium kuma-neurons ne-skeletal muscle (ulwelwesi oluqinisayo kanye **ne-excitability neuromuscular ecindezelayo **, okuphambene ncamashi ne-hypocalcemic tetany), iziguli ziba nobuthakathaka obukhulu i-proximal muscle reflexes, i-hyporeflex ejulile yemisipha ukudideka, i-acute delirium, paranoia/hallucinations, inkulumo engacacile, stupor, kanye nekhoma (ikakhulukazi uma i-calcium ilungisiwe idlula u-\(14\text{ ukuya }15\text{ mg/dL}\)).
2. Izinso ("Amatshe & I-Polyuria"): Isifo sikashukela i-Nephrogenic insipidus (ukoma okungapheli [i-polydipsia] nokuchama [i-polyuria]), ukuncipha okukhulu kwevolumu, i-calcium oxalate/phosphate nephrolithiasis (ubuhlungu be-flank), i-nephrocalcinosis, kanye nokulimala okukhulu kwe-prerenal + intrarenal.
3. Amathumbu ("Ukububula Kwesisu"): Imisipha ebushelelezi epheshaneni le-GI iba yi-hypotonic futhi ivilaphe, ibangele i-anorexia, isicanucanu esingalawuleki nokuhlanza, ukuvaleka okukhulu/ukuqunjelwa, nobuhlungu besisu. Ngaphezu kwalokho, i-calcium ephezulu ivuselela ukukhululwa kwe-gastrin (isifo sezilonda zesilonda) futhi isebenze ngaphambi kwesikhathi i-trypsinogen ngaphakathi kwamaseli e-pancreatic acinar, okubangela i-acute necrotizing pancreatitis.
4. Izinguquko ze-ECG zenhliziyo kanye ne-12-Lead:
5. Isikhawu esifushane se-QT / QTc: I-calcium ephezulu isheshisa ukuphindaphindeka kwe-plateau kweSigaba 2 samandla esenzo senhliziyo, idonsela igagasi le-T liye ngqo ngemuva kwenxanxathela ye-QRS (**ingxenye ye-ST efinyeziwe futhi ifinyeze isikhawu se-QTc \(< 340\text{ kuya ku-}360\text{ ms}\)*).
6. I-Osborn Waves (J-Waves) ku-Normothermic Patients: Kumaleveli e-calcium angaphezu kuka-\(14\umbhalo{ ukuya }ku-16\text{ mg/dL}\), ukuchezuka okuphozithiyo kwakudala ku-J-point (Osborn wave, okuvamise ukubonakala ku-hypothermia enzima) kuvela ku-ECG, elingisa i-ST-elevation myocardial infar
7. I-Bradyarrhythmias neHeart Block: Idigri yokuqala, idigri yesibili, noma okuphelele (idigri yesithathu) AV heart block, ibhulokhi yegatsha, ukuboshwa kwe-sinus, kanye ne-ventricular fibrillation engazelelwe.

Imibuzo evame ukubuzwa¶

Kungani i-calcium ephezulu egazini yenza umuntu aphelelwe amanzi emzimbeni kakhulu uma echama usuku lonke?¶

I-calcium ephezulu egazini ifaka ushevu ngokuqondile emishinini yezinso egxilisa amanzi, ibangele isimo esibizwa nge-calcium-induced nephrogenic diabetes insipidus. Ngokukhethekile, i-calcium eningi ivula ama-calcium-sensor receptors ku-Loop of Henle (esebenza njenge-non-stop loop diuretic elahla usawoti namanzi) futhi ivimbe imigudu yamanzi ye-Aquaporin-2 emiseleni eqoqayo ukuze izinso zingasakwazi ukuphendula ku-antidiuretic hormone (ADH). Ngenxa yalokhu, isiguli sichama amalitha angu-4 kuya kwangu-8 amanzi ahlanzekile, ahlanjululwe nsuku zonke kuyilapho ngesikhathi esifanayo sibhekana nesicanucanu esinamandla se-hypercalcemic nokuhlanza okusivimbela ukuba siphuze amanzi anele ukuze siqhubeke, sishiye amalitha angu-4 kuya kwangu-6 ephelelwe amanzi.

Kungani kuyingozi ngodokotela ukunikeza i-IV furosemide (Lasix) ngokushesha ukuze bakhiphe i-calcium ephezulu?¶

Emashumini eminyaka adlule, izincwadi zezokwelapha zafundisa odokotela ukuba banikeze kokubili i-furosemide evamile enosawoti kanye nedosi ephezulu ye-IV ukuze baphoqe izinso ukuba zikhiphe i-calcium. Ucwaningo lwezokwelapha kamuva lwafakazela ukuthi ukunikeza i-loop diuretic efana ne-furosemide ngaphambi kokuba isiguli sishodelwe amanzi ngo-4-to-6-litre wokuphelelwa amanzi emzimbeni sigcwaliswe ngokuphelele ngosawoti ovamile kuyingozi: kwandisa ukuphelelwa amanzi emzimbeni, kwehlise ukugeleza kwegazi kwezinso (GFR), futhi kuphoqelela ishubhu eliseduze lenso ukuthi limunce kabusha i-sodium ne-calcium eyengeziwe egazini, okwenza i-hypercalcemia ibe yimbi kakhulu. Namuhla, i-furosemide igodliwe ngokuqinile kuze kube yilapho umthamo we-intravascular ubuyiselwa ngokugcwele ngamalitha angu-0.9% we-saline evamile, futhi isetshenziswa kuphela uma isiguli siba nokugcwala koketshezi oluningi.

Kungani odokotela kufanele abale "Albumin-Corrected Calcium" ezigulini ezinomdlavuza?¶

Cishe amaphesenti angu-40 kuya kwangu-45 engqikithi ye-calcium entantayo egazini lakho iboshelwe kumaprotheni athwala, ngokuyinhloko i-albumin, kuyilapho amaphesenti angu-50 asele ekhululekile, esebenza ngokwebhayoloji "i-calcium ionized." I-calcium ionized yamahhala kuphela ithinta ubuchopho bakho, inhliziyo, nezinso. Iziguli eziningi ezinomdlavuza osekhulile noma izifo ezingelapheki zinezinga eliphansi kakhulu le-albumin egazini (hypoalbuminemia) ngenxa yokungondleki kahle noma ukuvuvukala. Uma i-albumin iphansi, ukuhlolwa kwelebhu "yengqikithi ye-calcium" okujwayelekile kubonakala kuphansi ngokukhohlisayo noma kuphakeme kancane ngisho noma i-calcium eyingozi ye-ionized yamahhala iphezulu kakhulu. Ukwengeza u-0.8 mg/dL engqikithini ye-calcium kuwo wonke u-1.0 g/dL i-serum albumin iwela ngaphansi kuka-4.0 g/dL (noma ukulinganisa i-calcium ionized eqondile) kuveza ubunzima bangempela benkinga.

Kungani odokotela benikeza kokubili i-Subcutaneous Calcitonin KANYE NE-Intravenous Zoledronic Acid ngesikhathi esisodwa?¶

I-Intravenous Zoledronic Acid (i-bisphosphonate enamandla) kanye ne-Subcutaneous Denosumab yizidakamizwa ezinamandla kakhulu zokuvala ukuphuka kwamathambo kanye nokugcina i-calcium yegazi evamile kumaviki angu-3 kuya kwangu-4, kodwa kuthatha amahora angu-48 kuya kwangu-96 (izinsuku ezimbili kuya kwezingu-4) ukuze ziqale ukusebenza. Ngokuphambene, i-Subcutaneous Salmon Calcitonin iqala ukwehlisa i-calcium egazini phakathi namahora angu-4 kuya kwangu-6 nje kuphela, kodwa iyeka ukusebenza ngokuphelele ngemva kwamahora angu-48 ngenxa yokuthi amangqamuzana amathambo afihla ngokushesha ama-calcitonin receptors (tachyphylaxis). Ukunikeza yomibili imithi ndawonye ngehora elingu-0 kusebenzisa iCalcitonin esebenza ngokushesha njengebhuloho lamahora angu-48 elisindisa ukuphila kuze kube yilapho i-Zoledronic Acid esebenza isikhathi eside noma i-Denosumab iqala ngoSuku lwesi-3.

Ukuhlolwa kwegazi okulula kwe-Parathyroid Hormone (PTH) kubatshela kanjani odokotela ukuthi i-calcium ephezulu ibangelwa umdlavuza noma isimila se-parathyroid gland?¶

Ku-Primary Hyperparathyroidism, enye yezindlala ezine ze-parathyroid ezincane ezisentanyeni isungule isimila esiyingozi (i-adenoma) noma i-hyperplasia ekhipha ngokuzenzakalelayo i-Parathyroid Hormone (PTH), ngakho ukuhlolwa kwelebhu kubonisa kokubili i-calcium ephezulu yegazi KANYE nezinga le-PTH eliphezulu (noma elingafanele) elingaguquki. Ku-Hypercalcemia of Malignancy, umdlavuza ukhuphula i-calcium yegazi ngokukhipha i-hormone elingisayo ebizwa ngokuthi i-PTHrP (engabhalisi esivivinyweni selebhu ye-PTH engaguquki) noma ngokuhlakazeka kwethambo, kanye nezindlala ze-parathyroid ezinempilo entanyeni zizwa i-calcium ephezulu esibhakabhakeni futhi zivale ukukhiqizwa kwazo kweqiniso kwe-PTH ngokuphelele (kucindezelwe ngaphansi kuka-1g0m2L eqinile).

Kusho ukuthini "Amathambo, Amatshe, Ukububula Kwesisu, kanye Nokwenyuka Kwengqondo"?¶

Lesi sisho sezokwelapha esivamile sifingqa izinqubo ezine zezitho ezishaywe yi-hypercalcemia: "Amathambo" abhekisela ebuhlungu obujulile obubuhlungu noma ukuphuka kwe-pathologic okuvela ku-calcium ekhishwa ku-skeleton (i-osteitis fibrosa cystica noma i-osteolytic metastases); "Amatshe" ibhekisela ezinso calcium amatshe kanye nephrogenic sikashukela insipidus dehydration; "Ukububula kwesisu" kubhekisela ekuqunjweni okukhulu, isicanucanu, ukuhlanza, izilonda ze-peptic, kanye ne-acute hypercalcemic pancreatitis; kanye nethi "Psychiatric Overtones" (noma "Moans") ibhekisela ekucindezelekeni, ukukhathala okukhulu, ukulahlekelwa inkumbulo, ukudideka, ukubona izinto ezingekho, kanye nekoma njengoba i-calcium ephezulu ibambezela ukudluliswa kwemizwa ebuchosheni.
