Abstract

Background: Nowadays, chronic kidney disease (CKD) is known as an epidemic disease all around the world. Chronic kidney disease considered as a serious health problem with numerous side effects, including complications progressive in reducing glomerular filtration rate (GFR), imbalances in the homeostasis of the body and decreased quality of life and finally an increase in mortality due to cardiovascular problems. End-stage renal disease leads to hypocalcemia and hyperphosphatemia, that as a result of, parathyroid hormone (PTH) will increased that secondary hyperparathyroidism will occurred eventually. So it is essential to routine examination of electrolytes in these patients. The current study have been done to determine the electrolytes in saliva as a non-invasive sample in hemodialysis patients in order to the saliva to be presented as an appropriate samples for clinical laboratories.

Methods: In the present case-control study that has been performed at Imam Ali Hospital, Bojnord, North Khorasan Province, Iran, in the summer of 2016, 44 hemodialysis patients and 44 aged, gender and body mass index (BMI) matched healthy controls were selected and then their cell count, Hb, HCT, iron, ferritin, total iron binding capacity (TIBC), glucose, CRP, triglycerides, cholesterol, urea, creatinine, calcium, phosphorus, potassium and PTH were measured.

Results: Calcium and phosphorus were higher in hemodialysis patients in comparison to the control group. Furthermore, there are not any significant relationship between levels of calcium, phosphorus and potassium in both serum and saliva samples. In addition, we observed the positive relationship between PTH in serum as well as phosphorus and potassium in the saliva.

Conclusion: The findings of current study have been shown that salivary levels of calcium and phosphorus in hemodialysis patients is higher than healthy people, therefor could be a non- invasive suitable marker for diagnosis. In addition, blood PTH levels in hemodialysis patients is associated with salivary levels of phosphorus and potassium, so, perhaps these parameters marked PTH's representative in the blood with further investigation of saliva’s electrolytes.

Abstract
Background: Adenoid cystic carcinoma (ACC) is a rare neoplasm of the major salivary glands, characterized by a slow-growing tumor, wide local infiltration, perineural spread, a propensity to local recurrence and distant metastasis, and has a poor prognosis. Although surgery and radiotherapy are considered standard treatments, the role of systemic therapy in advanced and metastatic stages remains unclear and rarely results in complete remission. Due to the rarity and limited number of reported cases, here, we report a complete response with systemic treatment in a case of metastatic ACC of the salivary gland.
Case Presentation: The patient is a 50-year-old woman with a history of ACC of the submandibular salivary gland at 20 years old. No recurrence of the disease was observed until, at 47 years old, when metastatic adenocarcinoma with salivary gland origin was diagnosed. From the age of 47 to 50 years, multiple cervical lymph node involvement, multiple masses in the parotid gland and thyroid tissue, as well as distant metastasis to the breast, ovary, and lungs were observed. The patient underwent cervical lymphadenectomy, total parotidectomy, and several courses of radiotherapy and chemotherapy. After six cycles of the Bevacizumab + Adriamycin + Cisplatin regimen, radiologic evaluation confirmed a complete response to the treatment with the disappearance of pulmonary nodules and parotid lesions. The patient is currently under follow-up.
Conclusion: Our reported case shows the aggressive nature of recurrent metastatic ACC of the salivary gland and the positive effect and importance of systemic treatment in these patients. Because the metastasis can appear very slowly, early diagnosis is essential for a better prognosis. These rare malignant lesions should be followed up for a long time after initial treatment due to slow growth, frequent recurrence and late and distant metastasis possibility. This case highlights the potential of systemic therapy to induce complete response even in extensively metastatic disease, suggesting that further clinical trials may be warranted.
