Sagliker syndrome in a patient with end-stage renal disease with secondary hyperparathyroidism

Sagliker Syndrome: A Case Report of Facial Deformities and Renal Osteodystrophy Secondary to Hyperparathyroidism in End-Stage Renal Disease

Sagliker syndrome (SS) is a rare but distinctive form of renal osteodystrophy associated with poorly managed secondary hyperparathyroidism (SHPT) in patients with chronic kidney disease (CKD). We present a case of a 28-year-old male with end-stage CKD on hemodialysis for 10 years, who exhibited progressive facial deformities and maxillofacial bone pain. Physical examination revealed bilateral expansion of the maxillary and mandibular bones and facial asymmetry. Radiological findings included diffuse bone thickening and multilocular cysts in the maxillofacial bones, while laboratory tests showed decreased levels of calcium and elevated parathyroid hormone, confirming SHPT. Despite multidisciplinary management involving nephrology, endocrinology, and maxillofacial surgery, the patient's condition deteriorated and he manifested community-acquired pneumonia leading to cardiopulmonary arrest and death. This case underscores the challenges in managing severe HPT in CKD and emphasizes the importance of early assessment and comprehensive multidisciplinary care to prevent irreversible complications.

Case report: Sagliker syndrome in the patient with recurrent tertiary hyperparathyroidism due to intrathyroidal parathyroid carcinoma

Sagliker syndrome (SS) is an extremely rare disorder that manifests in patients with advanced chronic kidney disease (CKD) undergoing programmed hemodialysis as a renal replacement therapy. Treatment of secondary hyperparathyroidism (SHPT) in these patients is still challenging. The main clinical manifestations of SS include craniofacial and fingertip deformities, dental anomalies, gingival hyperplasia, short stature, hearing loss, neurological and psychiatric impairment. The etiology and pathogenesis of SS in patients with SHPT require further clarification. However, mutations in the GNAS1, FGF23, and FGFR3 genes were described in some patients, suggesting a possible role of genetic predisposition to the syndrome. The preferred therapeutic approach for SS is surgery, but the volume of the operation is debated. The main surgical strategies include total, subtotal parathyroidectomy, or total parathyroidectomy with autotransplantation of the parathyroid gland (PG). Unfortunately, parathyroidectomy does not contribute to the regression of significant skeletal deformities. We present a unique clinical case of a patient with classical features of SS, recurrent tertiary hyperparathyroidism (THPT) after total parathyroidectomy due to intrathyroidal parathyroid carcinoma (PC).

A new anesthesia scheme for parathyroidectomy under neuromonitoring: a retrospective cohort study

Background

Parathyroidectomy under nerve monitoring has been carried out for nearly ten years in the China-Japan Union Hospital of Jilin University. We retrospectively evaluated patients' prognosis with secondary hyperparathyroidism (SH) under neuro- and non-neuro-monitored parathyroidectomy anesthesia. The purpose of this study is to summarize and introduce a new anesthesia scheme for parathyroidectomy under nerve monitoring.

Methods

From January 2000 to December 2019, 200 patients with SH in the China-Japan Union Hospital of Jilin University were retrospectively analyzed. Among them, 100 patients underwent parathyroidectomy under neurological monitoring (Group A), and 100 patients underwent parathyroidectomy without neurological monitoring (Group B). The dosage of muscle relaxant, parathyroid hormone (PTH), serum calcium, phosphorus, urea, creatinine, and alkaline phosphatase (ALP) was recorded before surgery (T0), after surgery (T1), at discharge (T2), during skin incision (Ta), at four parathyroidectomies (Tb), and 10 min after total removal. The levels of PTH were measured at four-time points (Tc) and 30 minutes (Td) after complete resection.

Results

After screening and propensity score match (PSM), the data of 92 patients were analyzed. Group A's muscle relaxant dose was significantly less than Group B; the length of hospital stay in Group A was significantly lower than in Group B (P<0.05). The serum calcium levels, phosphorus, urea, and creatinine at T2 in Group A were lower than those in Group B (P<0.05).

Conclusions

Parathyroid nerve monitoring technology combined with preoperative complete anesthesia scheme, anesthesia induction with one time ED95 (95% effective drug dose) cis-atracurium, end breath gas, and sevoflurane maintenance anesthesia under BIS monitoring can improve the prognosis of patients, shorten the length of hospital stay, and is effective and safe.
