Interventions to Reduce the Risk of Hypocalcemia After Parathyroidectomy for People With Advanced Chronic Kidney Disease: A Systematic Review
Notice bibliographique
Résumé
Background: People with advanced chronic kidney disease (CKD) and secondary hyperparathyroidism (sHPT) refractory to medical therapy often require surgical parathyroidectomy. Severe and prolonged hypocalcemia immediately following parathyroidectomy for sHPT is often termed "hungry bone syndrome" (HBS). Objective: To systematically review the effect of pre-operative interventions on post-operative hypocalcemia, HBS, and other related outcomes in patients with CKD and sHPT undergoing parathyroidectomy. Design: This is a systematic review study. Setting: Diverse study designs conducted in any country. Patients: Adult patients with CKD complicated by sHPT undergoing parathyroidectomy. Measurements: Post-operative hypocalcemia, HBS, symptomatic hypocalcemia, and other related outcomes. Methods: We searched Ovid MEDLINE, Embase, and Cochrane Controlled Trials Registry from inception until June 2024 for trials and observational studies of adults with CKD and sHPT that evaluated pre-operative interventions aimed at reducing the risk of hypocalcemia following parathyroidectomy. After 2 phases of study screening conducted in duplicate, we extracted data on study design, patient characteristics, interventions, and outcomes. Hypocalcemia was defined as serum calcium <2.1 mmol/L and HBS as calcium <2.1 mmol/L for ≥4 days post-operatively. We evaluated the risk of bias and completed a narrative synthesis of the available literature across intervention types. Results: We identified 3616 studies; 35 underwent full-text review, and 9 met final eligibility criteria. Interventions included pre-operative calcitriol (n = 2), pre-operative cinacalcet (n = 3), pre-operative alkaline phosphatase (ALP) measurement to guide intravenous (IV) calcium administration (n = 3), and pre-operative pamidronate (n = 1). All studies reported on at least one of: median/mean post-operative calcium (n = 7), incidence of post-operative hypocalcemia (n = 3), HBS (n = 1), and symptomatic hypocalcemia (n = 4). Interventions that reported on the risk of post-operative hypocalcemia included pre-operative pamidronate (n = 1, 37 participants, odds ratio [OR] = 0.003, 95% confidence interval [CI] = 0.000-0.072) and IV calcium guided by pre-operative ALP (n = 1, 271 participants, OR = 0.292, 95% CI = 0.175-0.488). There were insufficient data to meta-analyze study-specific effects for any intervention or outcome. Limitations: Our study was limited by significant heterogeneity in outcome reporting, which resulted in substantial outcome reporting bias and prevented pooled analyses. Furthermore, no randomized control trials met our inclusion criteria, which limited assessment of publication bias. Conclusions: Pre-operative risk factors for HBS have been established in patients with CKD undergoing parathyroidectomy. However, limited research has evaluated pre-operative interventions to reduce the risk of HBS, and due to heterogeneity in outcome reporting across studies, there is still uncertainty about the effectiveness of such interventions. These findings support the need for future clinical trials.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
