ABSTRACT
A 38-year-old female presented with irregular menstruation and hirsutism that started at age of 16 and diagnosed with polycystic ovary syndrome at age of 29 with elevated testosterone. When treated with ethinestradiol cyproterone tablets, her menstruation returned to normal and androgen levels was not changed. At age of 38 she was referred to the hospital with infertility, a diagnosis of nonclassical 21-hydroxylase deficiency was confirmed using 17-hydroxyprogesterone, dehydroepiandrosterone-sulfate, a cosyntropin-stimulation test and genetic test. This case suggested that nonclassical congenital adrenal hyperplasia should be considered when a patient is presented with oligomenorrhea, hirsutism with hyperandrogenemia and infertility.
ABSTRACT
Objective:To investigate the effect and regulation of umbilical cord-derived mesenchymal stem cells (UC-MSCs) on islets function and NOD-like receptor family, pyrin domain containing 3 (NLRP3) and autophagy in type 2 diabetic mellitus (T2DM) mice.Methods:Experimental study. Twenty, 8-week-old, male C57BL/6J mice were selected and divided into a normal control group ( n=5) and a high-fat feeding modeling group ( n=15). The model of T2DM was established by high-fat feeding combined with intraperitoneal injection of low-dose streptozotocin. After successful modeling, those mice were divided into a diabetes group ( n=7) and a UC-MSCs treatment group ( n=7). The UC-MSCs treatment group was given UC-MSCs (1×10 6/0.2 ml phosphate buffer solution) by tail vein infusion once a week for a total of 4 weeks; the diabetes group was injected with the same amount of normal saline, and the normal control group was not treated. One week after the treatment, mice underwent intraperitoneal glucose tolerance tests and intraperitoneal insulin tolerance tests, and then the mice were sacrificed to obtain pancreatic tissue to detect the expressions of interleukin-1β (IL-1β) and pancreatic and duodenal homeobox 1 (PDX-1) by immunofluorescence. The bone marrow-derived macrophages were stimulated with lipopolysaccharide and adenosine triphosphate (experimental group) in vitro, then co-cultured with UC-MSCs for 24 h (treatment group). After the culture, enzyme-linked immunosorbent assay was used to detect the secretion level of IL-1β in the supernatant, and immunofluorescence staining was used to detect the expression of NLRP3 inflammasome, and related autophagy proteins. Statistical analysis was performed using unpaired one-way analysis of variance, repeated measure analysis of variance. Results:In vivo experiments showed that compared with the diabetes group, the UC-MSCs treatment group partially repaired islet structure, improved glucose tolerance and insulin sensitivity (all P<0.05), and the expression of PDX-1 increased and IL-1β decreased in islets under confocal microscopy. In vitro experiments showed that compared with the experimental group, the level of IL-1β secreted by macrophages in the treatment group was decreased [(85.9±74.6) pg/ml vs. (883.4±446.2) pg/ml, P=0.001], the expression of NLRP3 inflammasome and autophagy-related protein P62 was decreased, and the expressions of microtubule-associated protein 1 light chain 3β (LC3) and autophagy effector Beclin-1 were increased under confocal microscopy. Conclusions:UC-MSCs can reduce the level of pancreatic inflammation in T2DM mice, preserving pancreatic function. This might be associated with the ability of UC-MSCs to inhibit the activity of NLRP3 inflammasomes in macrophages and enhance autophagy levels.
ABSTRACT
Objective:To summarize the correlation between anterior pituitary function and tumor size in patients with different hormone-secreting pituitary adenomas.Methods:This was a retrospective case series study. The clinical data of 1 946 patients with pituitary adenoma hospitalized in the First Medical Center of Chinese PLA General Hospital from January 1, 2005, to December 31, 2020, were collected. The correlation between tumor size and anterior pituitary hormone levels was analyzed using Spearman rank correlation analysis in different types of pituitary adenomas.Results:The median age of the 1 946 patients was 45.1 years, of which 857 (44.0%) were men. The maximum tumor diameter of the patients [ M ( Q1, Q3)] was 22 (14, 30) mm. Tumor size in nonfunctioning adenomas ( n=1 191) was negatively correlated with adrenocorticotropic hormone (ACTH) ( r=-0.11, P<0.001), growth hormone ( r=-0.13, P<0.001), and luteinizing hormone (men: r=-0.26, P<0.001, women: r=-0.31, all P<0.001). The tumor size of somatotropic adenomas ( n=297) was positively correlated with growth hormone ( r=0.46, P<0.001), but negatively correlated with male testosterone ( r=-0.41, P<0.001). The tumor size of ACTH-secreting pituitary adenomas ( n=155) was positively correlated with the ACTH level at 8∶00 AM ( r=0.25, P<0.001); however, no correlation was found with cortisol at 8∶00 AM ( P>0.05). The tumor size of prolactinomas ( n=303) was positively correlated with the prolactin level (men: r=0.34, P=0.001; women: r=0.13, P=0.070). Conclusions:The correlation between the function of the anterior pituitary and size of the tumor depends on the cellular origin of the pituitary adenoma and specific type of hormone secretion. In somatotroph adenomas, ACTH-secreting pituitary adenomas, and prolactinomas, there is a positive correlation between tumor size and level of hormones secreted by the corresponding tumors. In patients with nonfunctioning adenomas, the tumor size was negatively correlated with the hormone levels of the pituitary-adrenal and pituitary-growth hormone axes.
ABSTRACT
Objective:To explore the characteristics of the association between the triglyceride glucose (TyG) index and nonfatal cardio-cerebrovascular disease risk in a community population.Method:This was a prospective cohort study. From December 2011 to April 2012, the first investigation was conducted among subjects with more than 40-year old who were from Shijingshan district and Pingguoyuan community in Beijing. The second investigation was conducted from April to October 2015. All the subjects were divided into three groups according to the tertile of the TyG index at baseline. The multivariate Cox proportional risk regression model was established to explore the correlation between the TyG index and nonfatal cardio-cerebrovascular disease risk and the Kaplan-Meier survival curve of the TyG index group was drawn. Subgroup analyses were performed according to age, gender, body mass index, type 2 diabetes mellitus (T2DM), hypertension, and hyperlipidemia to determine the correlation characteristics between the TyG index and nonfatal cardio-cerebrovascular disease among subgroups.Results:A total of 9 577 subjects were finally included to analyze. The mean follow-up time of this study was (34.14±3.84) months. During the follow-up, 363 subjects (3.8%) occurred nonfatal cardio-cerebrovascular disease. The multivariate Cox regression analysis results showed that the hazard ratio ( HR) of nonfatal cardio-cerebrovascular disease in the high TyG index group was 1.54 (95% CI 1.19-1.98), 1.60 (95% CI 1.23-2.10), and 1.57 (95% CI 1.20-2.05) in the three models, compared with the low TyG index group. The Kaplan-Meier analysis showed that the risk of nonfatal cardio-cerebrovascular disease increased from the low-TyG index group to the high-TyG index group ( P=0.015). In the six subgroups analysis, only gender was shown to have a significant interaction effect with the TyG index and nonfatal cardio-cerebrovascular disease risk. In the female population, the risk of nonfatal cardio-cerebrovascular disease is significantly increased with the increase in the TyG index level ( P<0.001). Conclusions:A high TyG index is independently related to the increased risk of nonfatal cardio-cerebrovascular disease in the Beijing community population. Gender has a significant interaction with the TyG index and nonfatal cardio-cerebrovascular disease risk. Therefore, the TyG index may be a useful marker to predict the nonfatal cardio-cerebrovascular disease risk of a community population.
ABSTRACT
Objective:To investigate the association between reproductive lifespan duration (RLD) and urinary albumin-creatinine ratio (UACR) in a Chinese postmenopausal population.Methods:This cross-sectional study included 11 055 naturally postmenopausal women from seven regions of China from May to December 2011. RLD was divided into four groups. Propensity score matching was performed to reduce bias, and logistic regressions and stratifications were conducted to investigate the association between RLD and increased UACR (≥30 mg/g). Mediation effect analysis was performed to quantify the effect of RLD on cardiovascular disease (CVD) induced by elevated UACR.Results:There were 2 373 participants with a RLD of 18-31 years, 2 888 participants with a RLD of 32-34 years, 2 472 participants with a RLD of 35-36 years, and 3 322 participants with a RLD of 37-50 years. The shortest RLD (18-31 years) group was characterized with older age ( P<0.001), a higher incidence of CVD ( P=0.025), and the highest level of UACR ( P<0.001). After adjusting for confounders, women with a longer RLD (37-50 years group) exhibited a lower risk of UACR elevation compared with those with the shortest RLD (18-31 years group) ( OR=0.72, 95% CI 0.64-0.82, P<0.001). Every 1-year extension in RLD was linked to a 2% reduction in the risk of UACR elevation ( OR=0.98, 95% CI 0.97-0.99, P<0.001). Stratified analysis revealed a more significant association between RLD and UACR in women who were a normal weight ( P=0.003) or overweight ( P=0.001), in those without CVD history ( P=0.001), and in those with impaired estimated glomerular filtration rate ( P=0.004). The mediation casual analysis showed that 3.0% of proteinuria inducing CVD events was mediated by RLD ( P=0.048). Conclusion:A longer RLD (37-50 years) is associated with a lower UACR in Chinese postmenopausal women.
ABSTRACT
Objective:Development and validation of a nomogram for predicting the 4-year incidence of type-2 diabetes mellitus (T2DM) in a Chinese population was attempted.Methods:This prospective cohort study was conducted in Shijingshan District Pingguoyuan Community (Beijing, China) from December 2011 to April 2012 among adults aged≥40 years not suffering from T2DM. Finally, 8 058 adults free of T2DM were included with a median duration of follow-up of 4 years. Participants were divided into a modeling group and verification group using simple random sampling at a ratio of 7∶3. Univariate and multivariate Cox proportional risk models were applied to identify the independent risk predictors in the modeling group. A nomogram was constructed to predict the 4-year incidence of T2DM based on the results of multivariate analysis. The Concordance Index and calibration plots were used to evaluate the differentiation and calibration of the nomogram in both groups.Results:A total of 5 641 individuals were in the modeling group and 2 417 people were in the validation group, of which 265 and 106 had T2DM, respectively, at 4-year follow-up. In the modeling group, age ( HR=1.349, 95% CI 1.011-1.800), body mass index ( HR=1.347, 95% CI 1.038-1.746), hyperlipidemia ( HR=1.504, 95% CI 1.133-1.996), fasting blood glucose ( HR=4.189, 95% CI 3.010-5.830), 2-h blood glucose level according to the oral glucose tolerance test ( HR=3.005, 95% CI 2.129-4.241), level of glycosylated hemoglobin ( HR=3.162, 95% CI 2.283-4.380), and level of γ-glutamyl transferase ( HR=1.920, 95% CI 1.385-2.661) were independent risk factors for T2DM. Validation of the nomogram revealed the Concordance Index of the modeling group and validation group to be 0.906 (95% CI 0.888-0.925) and 0.844 (95% CI 0.796-0.892), respectively. Calibration plots showed good calibration in both groups. Conclusion:These data suggest that our nomogram could be a simple and reliable tool for predicting the 4-year risk of developing T2DM in a high-risk Chinese population.
ABSTRACT
The clinical data, laboratory test, and gene mutations were collected from a family with Liddle syndrome. Literatures on Liddle syndrome published in domestic and abroad since 1994 were reviewed and the types of gene mutations were summarized. The proband was diagnosed with hypertension at the age of 24. Laboratory test showed that serum potassium was 3.65 mmol/L, plasma renin was <0.5 mU/L, and plasma aldosterone was 1.5 ng/dL. Proband′s father was diagnosed with hypertension at the age of 34 with the serum potassium 3.34 mmol/L, plasma renin 3.72 mU/L, and plasma aldosterone 6.04 ng/dL. A nonsense mutation(1724G>A, p.Trp575*) in exon 13 of SCNN1G gene was detected in the proband and his father. In 288 cases from 107 families reported in the review of domestic and foreign literature, the incidence of hypertension, hypokalemia, and low renin/low aldosterone were 95.1%, 55.2%, and 49.6%, respectively. This case suggests that the clinical phenotype of Liddle syndrome is heterogeneous. Patients with early-onset hypertension, regardless of whether they are accompanied by hypokalemia, should be screened for renin-angiotensin-aldosterone and genetic testing related to Liddle syndrome should be further detected in patients with low plasma renin/aldosterone.
ABSTRACT
Objective:To provide insight into the diagnosis for clinicians, the clinical characteristics, diagnosis and treatment history of 3 patients with 21-hydroxylase deficiency (21-OHD) and testicular adrenal rest tumors (TART) were analyzed.Methods:The clinical, laboratory and imaging data of 3 male patients with 21-OHD and TART, confirmed with CYP21 gene sequencing, from May 2010 to May 2021 in the First Medical Center of Chinese PLA General Hospital were analyzed retrospectively. The treatment strategy and clinical outcome were followed up.Results:All the 3 patients were first diagnosed with bilateral adrenal mass at the age of 27-42 years old. They were 145-162 cm tall. The levels of progesterone, 17-hydroxyprogesterone, and adrenocorticotropic hormone (ACTH) of the 3 patients were relatively high, and that of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) of the 3 patients were low. Testosterone level of 1 patient was significantly elevated, and that of the other 2 patients was below the lower limit of normal range. Testicular ultrasound showed heterogeneous hyperechoic masses in both testes. CT of the adrenal glands showed bilateral adrenal enlargement with mass. All 3 patients were treated with dexamethasone. After 4-96 months of follow-up, 17-hydroxyprogesterone level was kept above the median normal level. One of the patients got married and had a baby after treatment. The sizes of adrenal hyperplasia and testicular masses reduced to various degrees with the change of the testicular masses being proportional to that of adrenal hyperplasia.Conclusions:Patients with 21-OHD are prone to have TART, leading to the impaired testicular function. Early glucocorticold therapy is beneficial to the reduction of TART and restoration of testicular function.
ABSTRACT
Objective:To analyzed clinical characteristics of pituitary growth hormone(GH) adenomas patients with different responses to oral glucose inhibitory GH test.Methods:The clinical data of 50 patients with pituitary GH adenomas newly diagnosed with complete test data and case data in the Department of Endocrinology of Chinese PLA General Hospital was retrospectively analyzed from 2016 to 2021. The cases were divided into two groups according to the cutoff point of GH elevating to 50% of basaline during oral glucose test: abnormal elevation group(A group, n=16) and non-elevation group(B group, n=34). The clinical features, biochemistry, iconography, and immunohistochemistry of the two groups were analyzed. Results:The serum total cholesterol(TC)[(3.9±0.8) vs (4.6±0.9)mmol/L], 120 minutes insulin after glucose loading [11.2(4.4, 25.0) vs 92.0(10.8, 311.8)mU/L], long [1.0(0.4, 2.1) vs 1.5(0.5, 7.3) cm] and short[0.6(0.3, 1.3) vs 1.0(0.5, 5.8)cm] diameters of adenomas in A group were less than those in B group(all P<0.05) while insulin-like growth factor Ⅰ(IGF-Ⅰ) level was higher [(908.2±233.7) vs (743.1±273.1) ng/mL, P<0.05]. There were no significant differences in sex, age, disease course, clinical features, random GH, homeostasis model assessment of insulin resistance index(HOMA-IR), pituitary adenoma site, and invasive properties between the two groups. The immunohistochemical positive rates of ACTH(33% vs 0%) and prolactin(100% vs 28.6%)in A group were higher than those in B group( P<0.05). Conclusion:Pituitary GH adenomas patients with a paradoxical GH response pattern display lower serum TC and 120 minutes insulin levels as well as higher IGF-Ⅰ concentration and proportion of pituitary microadenomas. " Pure" growth hormone tumors may represent entities of a particular class of diseases in acromegaly.
ABSTRACT
Objective:To investigate the influence of hemoglobin glycation index (HGI) on the risk of incident chronic kidney disease (CDK) among nondiabetic patients.Methods:Prospective cohort study. At baseline, a total of 7 407 nondiabetic patients without a history of CKD from Pingguoyuan Community of the Shijingshan District in Beijing were included from December 2011 to August 2012, who were then divided into three groups according to the tertiles of their baseline HGI levels. The CKD incidence rate was compared among the different HGI groups at last follow-up. Cox multivariable regression was applied to evaluate whether HGI measures predicted CKD risk. Test for trend across tertiles were examined using ordinal values in separate models.Results:The mean age of the subjects was (56.4±7.5) years, and 4 933 (66.6%) were female. At mean follow-up of 3.23 years, 107 (1.4%) individuals developed CKD. The incidence of CKD was gradually increasing from the low to high HGI groups [1.1% (28/2 473) vs. 1.2% (31/2 564) vs. 2.0% (48/2 370), P=0.016]. In the multivariate Cox regression analysis, after adjustment for potential confounders, the high HGI group had a 68.5% increased risk of CKD compared with the low HGI group ( HR=1.685, 95% CI 1.023 to 2.774). CKD risk increased with increasing HGI tertiles ( P for trend=0.028). Conclusion:High HGI is associated with an increased risk for CKD in the nondiabetic population, indicating that HGI may help identify individuals at high risk for CKD.
ABSTRACT
Cystic lesions in the sellar region are one of the special types of space-occupying lesions in the sellar region, including cystic pituitary adenoma, craniopharyngioma, Rathke′s cyst, pituitary apoplexy, pituitary abscess, arachnoid cyst, epidermoid Cysts, etc. Each type of lesion has its corresponding treatment principles and strategies, and the prognosis also varies. Therefore, a clear preoperative diagnosis helps to hammer out the right treatment plan. If the volume of cystic lesions in the sellar region increases to a certain extent, mass effect and changes in pituitary hormones may occur. Different types of cystic lesions have their own characteristics, so as MRI and other imaging. In this paper, the diagnosis and differential diagnosis are analyzed and summarized based on clinical and imaging features, flow chart of differential diagnosis is developed.
ABSTRACT
Severe acute pancreatitis progresses rapidly, with many complications and high mortality. Currently, the clinical treatment of severe acute pancreatitis is limited, so it is of great significance to control and treat the organ failure and long-term complications caused by severe acute pancreatitis. Mesenchymal stem cells play a beneficial role on severe acute pancreatitis therapy by promoting tissue regeneration, antioxidation, regulating autophagy and secreting anti-inflammatory factors. This paper summarized the current research status of mesenchymal stem cells on severe acute pancreatitis therapy and also showed the application of exosomes and the regulation of macrophage polarization, to provide new ideas and new targets for the treatment of severe acute pancreatitis.
ABSTRACT
Diabetes is the most important comorbidity of cardiovascular disease, and cardiovascular disease is the main cause of mortality and disability of patients with type 2 diabetes. In order to standardize the diagnosis and treatment of patients with diabetes and cardiovascular disease, the National Health Commission Capacity Building and Continuing Education Center organized the experts from the field of cardiology and endocrinology systematically reviewing the research progresses and expert experiences of relevant disciplines from home and abroad, and formulated this consensus. This consensus covers the diagnosis, drug treatment, and risk factor management for patients with diabetes and cardiovascular disease (including atherosclerotic cardiovascular disease and heart failure) from the perspective of cardiovascular disease and diabetes management aiming to strengthen the comprehensive management of patients and ultimately to improve the prognosis of patients. The management of cardiovascular diseases mainly includes the management of blood pressure, blood lipids, anti-thrombosis, anti-myocardial ischemia, anti-ventricular remodeling and so on. Diabetes management mainly includes lifestyle intervention (including diet, exercise, weight loss, etc.), anti-hyperglycemia therapy (including drugs and insulin), blood glucose monitoring, and hypoglycemic prevention. In addition, specific clinical recommendations are given to patients with special health care needs such as diabetic nephropathy, elderly (>75 years), and cardiovascular critical illness.
ABSTRACT
We reported a case of polyglandular syndrome induced by programmed death-1(PD-1) inhibitors. The patient was a 51-years-old male with non-small cell lung cancer, treated with PD-1 inhibitor nivolumab/pembrolizumab because of postoperative subcarinal lymph node metastasis indicated by PET-CT. During 14 cycles of PD-1 inhibitor treatment, the patient successively developed primary hypothyroidism, and type 1 diabetes mellitus(T1DM). More than five months after the withdrawal of pembrolizumab, the patient experienced recurrentce. Laboratory examinations showed mild hyponatremia and hypopituitarism including ACTH and growth hormone(GH)/insulin-like growth factor-1(IGF-1) insufficiency. This is the first report of a patient diagnosed as polyglandular syndrome caused by PD-1 inhibitor. In particularly, the hypothyroidism and T1DM did not improve after drug withdrawal, while hypopituitarism was further aggravated. This case reminds us that we should pay more attention to the changes of endocrine function during and after the treatment of PD-1 inhibitor, so that we can make the correct diagnosis and take proper medical measures timely, to avoide missed diagnosis, and improper treatment.
ABSTRACT
Objective:To analyze the clinical characteristics of fulminant type 1 diabetes (FT1DM) in China.Methods:Clinical data of 279 cases related to FT1DM in Chinese Database from January 2005 to December 2018 were collected, and other 20 patients from our hospital were included in the present study.Results:(1) There has been a progressive increasing in the number of reported cases every year in China, and the number in the southern region were significantly more than that in the northern region. (2) The median age of the onset of FT1DM patients in China was 32.5 years old, without significant gender difference. Moreover, 36.5% (54/148) of the female patients caught the disease during their prenatal period, most of them were onset in the second or third trimesters of pregnancy and 2 weeks after delivery (37/40), and the prognosis of the fetus was extremely poor. (3) Compared with new-onset type 1 diabetes, FT1DM patients were younger, and with higher blood glucose [(39.7±15.3) vs (21.2 ± 9.9) mmol/L], higher serum creatinine [(188.4±115.9) vs (51.8 ±23.1) μmol/L], and higher amylase levels [245.5 (26.0-5 137.0) vs 54.7 (14.0-404.9) U/L]. FT1DM patients were with more severe acidosis, and lower HbA 1C level [(6.6 ±0.8)% vs (12.9 ± 2.5)%, P<0.01]. (4) FT1DM patients may combine with multiple organ dysfunction or severe metabolic disorders, electrolyte disorders, as well as liver and kidney dysfunctions, and elevation of amylase and muscle enzymes. Conclusion:FT1DM are with some clinical characteristics different from classic new-onset type 1 diabetes, including adult-onset, frequent in the southern China. Pregnancy may be a predisposing factor for female patients. Significant metabolic disorders and multiple organ involvements are common in the patients with FT1DM.
ABSTRACT
To discuss the clinical features and treatment of a 27-year-old female patient with Hashimoto thyroiditis and thyroxine autoantibody(T 4Ab) positive complained of abnormal thyroid function. The patient had no special clinical manifestations. Multiple measurements of thyroid function showed that surum FT 4 and TT 4 were elevated, while FT 3 and TT 3 remained normal, TSH was mainly elevated(occasionally normal or slight inhibited). We considered the possibility of the existence of laboratoury errors based on the inconsistency between the laboratory examination and clinical features, and the presence of T 4Ab was effectively confirmed by radioimmunoassay after comparing the test results of different methods and immunoprecipitation method. THAAb is a relatively rare antibody, which often leads to clinical misdiagnosis or even mistreatment. Therefore, clinicians should pay great attention to it.
ABSTRACT
This article reported a case of malignant pheochromocytoma and paraganglioma with cranial metastasis. The patient was a 25-year-old man. At the age of 10, he was diagnosed with retroperitoneal paraganglioma. He received radiotherapy after partial resection of the tumor. At the age of 15, when he consulted for headache and hypertension, a space occupying lesion was found on the right adrenal without further diagnosis and treatment. His headache and hypertension were aggravated at the age of 25. Then he visited our medical center and diagnosed with right adrenal pheochromocytoma. He undertook an operation to remove the right adrenal lesion, and his blood pressured could be controlled in the normal range with oral antihypertensive medication. One year after the surgery, a cranial lesion with positive 131I-metaiodobenzylguanidine imaging was found following the increase of norepinephrine and dopamine in both blood and urine. The diagnosis of malignant pheochromocytoma with cranial metastasis was confirmed. The cranial lesion was treated with cyberknife therapy for 4 times, and the lesion was slightly reduced. Four year after the removal of right adrenal tumor, he developed multiple bone metastasis in the right ribs and left ilium, and then he received 131I-metaiodobenzylguanidine radiotherapy. Additionally, the results of gene test indicated a pathogenic mutation of SDHB. During the follow-up period of one year after the treatment, his blood pressure fluctuated to about 140/90mmHg with 10mg of phenoxybenzamine once a day. The case is a malignant pheochromocytoma with multiple bone metastasis characterized by a long course with an ideal prognosis in a way. Consequently, we suggested the diagnostic pathway with genetic testing based on clinical phenotype to approach more timely diagnosis and reasonable evaluation of the prognosis in pheochromocytoma and paraganglioma. Furthermore, clinicians should pay more attention to the long-term surveillance.
ABSTRACT
Cushing′s syndrome during pregnancy is a very rare clinical condition, but can be seriously detrimental to mothers and fetuses. The gestation could lead to an increase of endogenous adrenal cortisol which could mimick the symptoms of Cushing′s syndrome and also cause difficulty in biochemical diagnosis. Moreover, the therapy of Cushing′s syndrome need to be optimized based on the classification of the pathogenesis, the timing of terminating pregnancy should be considered prudently and comprehensively in this condition. This article mainly reviews the diagnosis and therapies of Cushing′s syndrome concomitant with pregnancy and provides possible suggestions for the management of this condition.
