Abstract
BACKGROUND Previous studies suggest that free thyroxine may be used as a severity indicator of patients with acute pancreatitis (AP) in emergency department, helping determine the differential care of AP. However, there are no systematic reviews and the association between free thyroxine and AP is still not completely understood. Therefore, we will undertake a systematic review of the literature to summarize previous evidence regarding this topic, in order to clarify whether free thyroxine can help us pick out the mild AP cases. METHODS : We will search the EMBASE, Web of Knowledge, PubMed, ClinicalTrials.gov, and Cochrane Library from inception to Mar 2021 to retrieve relevant studies using the search strategy: ("free thyroxine") AND (pancreatitis OR pancreatitides). Two authors independently judged study eligibility and extracted data. Heterogeneity will be examined by computing the Q statistic and I2 statistic. RESULTS : This study proved the efficiency of free thyroxine in predicting the severity of patients with AP. CONCLUSIONS : This study will provide reliable evidence-based evidence for the clinical application of free thyroxine predicting the severity of patients with AP. ETHICS AND DISSEMINATION Ethical approval is unnecessary as this protocol is only for systematic review and does not involve privacy data. The findings of this study will be disseminated electronically through a peer-review publication or presented at a relevant conference.

Inhibition of macrophage migration inhibitory factor prevents thyroid dysfunction in pregnant rats with acute pancreatitis. Int Immunopharmacol 2020; 87:106771. [PMID: 32683302 DOI: 10.1016/j.intimp.2020.106771] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2019] [Revised: 02/20/2020] [Accepted: 06/30/2020] [Indexed: 01/14/2023]
Abstract
Acute pancreatitis during pregnancy (APIP) rarely occurs but may lead to preterm delivery and be associated with high fetal mortality. Macrophage migration inhibitory factor (MIF) participates in various inflammatory diseases as a pro-inflammatory cytokine. In this study, we aimed to explore the effects of (S, R)-3-(4-hydroxyphenyl)-4, 5dihydro-5-isoxazole acetic methyl ester (ISO-1), an inhibitor of MIF, on maternal thyroid injury associated with APIP and its potential mechanisms in a pregnant rat model. APIP model was induced by retrograde injection of sodium taurocholate. ISO-1 was injected intraperitoneally 30 min before model establishment. The severity of pancreatitis was assessed by levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β, IL-6 of maternal serum as well as histopathological score. Thyroid injury was determined by free triiodothyronine (FT3), free tetraiodothyronine (FT4) and thyroid histopathological score. Levels of MIF in maternal serum and the expression of MIF, CD68, CD3 and intercellular cell adhesion molecule-1 (ICAM-1) as well as oxidative stress status in maternal thyroid tissues were detected. Ultrastructure of maternal thyroid tissues was observed by transmission electron microscope. Thyroid injuries occurred in APIP and the lesions were attenuated with the pretreatment of ISO-1. Moreover, ISO-1 reduced the expression of MIF, attenuated the activations of CD68, CD3, ICAM-1 while improved oxidative stress status in maternal thyroid. Our research suggested a protective role of ISO-1 on thyroid injury and endocrine disorder during APIP, which may be associated with the inhibition of biological functions of MIF.

Abstract
Acute pancreatitis in pregnancy (APIP), which was thought to be a rare but severe disease, with a high perinatal mortality among maternal-fetuses. Our research aimed to study and assess thyroid injury in a rat model of APIP and its possible mechanisms. The APIP model was established by retrograde injection with sodium taurocholate. Sham-operated (SO) and APIP groups were performed at 3 time-points. Histological changes in the maternal thyroid and pancreas were assessed. The activities of serum amylase, lipase and levels of FT3, FT4, MDA, TNF-α and IL-1β were detected in maternal rats, and the expression of MIF, ICAM-1 and CD68 in the maternal thyroids were determined. In this study, maternal thyroid injury as well as pancreas injury occurred in a time-dependent manner. The activities of serum amylase, lipase and levels of MDA, TNF-α and IL-1β were markedly increased in acute pancreatitis rats, the levels of serum FT3 and FT4 were obviously decreased in APIP groups, and the expressions of MIF, ICAM-1 and CD68 were significantly increased in the thyroid of the APIP group. Ultrastructural thyroid injuries were observed in the APIP group. Our research suggests that thyroid injury is involved in the rat experimental model of APIP. The degree of thyroid dysfunction is associated with APIP, which may affect the prognosis of acute pancreatitis.
