Bilateral giant adrenal myelolipoma associated with congenital adrenal hyperplasia / Mielolipoma adrenal gigante bilateral associado a hiperplasia adrenal congênita

Adrenal myelolipomas are rare benign tumors, often non-functioning, located in the adrenal cortex, consisting mainly of mature adipose tissue and hematopoietic tissue. Although uncommon, the number of reported cases has increased due to the greater use of diagnostic imaging techniques. This tumor is usually unilateral and found as an adrenal incidentaloma, although there is a predominance of bilaterality in patients with congenital adrenal hyperplasia (CAH). In this study, we report the case of a 33-year-old male patient with CAH due to 21-hydroxylase deficiency, in non-regular use of the control medication, with bilateral giant adrenal myelolipoma and subsequent evolution of bilateral testicular adrenal rest tumors. He underwent bilateral adrenalectomy by video laparoscopy. The anatomopathological analysis, which confirmed myelolipomas' diagnosis, revealed the right adrenal with 430 g and 12.5 x 9.3 cm and the left with 257 g and 11.5 x 10.4 cm. This tumor may be accompanied by adrenocortical adenoma and carcinoma, ganglioneuroma, pheochromocytoma, Addison's disease, Cushing's syndrome, or CAH. Among the hypotheses of its pathogenesis, we highlight an association between the development of adrenal myelolipoma and chronic hormonal stimulation by the adrenocorticotrophic hormone (ACTH), especially in CAH. The non-regular treatment of CAH with glucocorticoids may have contributed to the chronic and elevated secretion of ACTH and, consequently, to the development of bilateral giant adrenal myelolipoma (AU).

Mielolipomas adrenais são tumores benignos raros, com frequência não-funcionantes, localizados no córtex da adrenal, constituídos, principalmente, por tecido adiposo maduro e tecido hematopoético. Apesar de incomum, o número de casos relatados tem aumentado devido ao maior uso de técnicas diagnósticas de imagens. Esse tumor é geralmente unilateral e encontrado como um incidentaloma adrenal, embora haja predominância de bilateralidade em casos de portadores de hiperplasia adrenal congênita (HAC). Neste estudo, relatamos o caso de um paciente do sexo masculino, de 33 anos, portador de HAC por deficiência de 21-hidroxilase, em uso não-regular da medicação de controle, com mielolipoma adrenal gigante bilateral e posterior evolução de tumor bilateral testicular de restos de adrenais. Ele foi submetido à adrenalectomia bilateral por videolaparoscopia. A análise anátomo-patológica, que confirmou o diagnóstico de mielolipomas, revelou adrenal direita com 430 g e 12,5 x 9,3 cm, e esquerda com 257 g e 11,5 x 10,4 cm. Esse tumor pode vir acompanhado de adenoma e carcinoma adrenocortical, glanglioneuroma, feocromocitoma, doença de Addison, Síndrome de Cushing ou HAC. Dentre as hipóteses de sua patogênese, des-tacamos uma associação entre o desenvolvimento do mielolipoma adrenal e a estimulação hormonal crônica pelo hormônio adrenocorticotrófico (ACTH), especialmente na HAC. O tratamento não-regular da HAC com glicocorticoides pode ter contribuído para a secreção crônica e elevada de ACTH e, consequentemente, para o desenvolvimento do mielolipoma adrenal gigante bilateral (AU).

Protective Effects and Mechanisms of Huangqi Decoction Against Radiation-Induced Bystander Effects / Efectos Protectores y Mecanismos de la Decocción de Huangqi Contra los Efectos Secundarios Inducidos por la Radiación

SUMMARY: The 12C6+ heavy ion beam irradiation can cause bystander effects. The inflammatory cytokines, endocrine hormones and apoptotic proteins may be involved in 12C6+ irradiation-induced bystander effects. This study characterized the protective effects and mechanisms of Huangqi decoction (HQD) against 12C6+ radiation induced bystander effects. Wistar rats were randomly divided into control, 12C6+ heavy ion irradiation model, and high-dose/medium-dose/low-dose HQD groups. HE staining assessed the pathological changes of brain and kidney. Peripheral blood chemical indicators as well as inflammatory factors and endocrine hormones were detected. Apoptosis was measured with TUNEL. Proliferating cell nuclear antigen (PCNA) expression was determined with real-time PCR and Western blot.Irradiation induced pathological damage to the brain and kidney tissues. After irradiation, the numbers of white blood cells (WBC) and monocyte, and the expression of interleukin (IL)-2, corticotropin-releasing hormone (CRH) and PCNA decreased. The damage was accompanied by increased expression of IL-1β, IL-6, corticosterone (CORT) and adrenocorticotropic hormone (ACTH) as well as increased neuronal apoptosis. These effects were indicative of radiation-induced bystander effects. Administration of HQD attenuated the pathological damage to brain and kidney tissues, and increased the numbers of WBC, neutrophils, lymphocyte and monocytes, as well as the expression of IL-2, CRH and PCNA. It also decreased the expression of IL-1β, IL-6, CORT and ACTH as well as neuronal apoptosis. HQD exhibits protective effects against 12C6+ radiation-induced bystander effects. The underlying mechanism may involve the promotion of the production of peripheral blood cells, inhibition of inflammatory factors and apoptosis, and regulation of endocrine hormones.

La irradiación con haz de iones pesados 12C6+ puede provocar efectos secundarios. Las citoquinas inflamatorias, las hormonas endocrinas y las proteínas apoptóticas pueden estar involucradas en los efectos secundarios inducidos por la irradiación 12C6+. Este estudio caracterizó los efectos y mecanismos protectores de la decocción de Huangqi (HQD) contra los efectos externos inducidos por la radiación 12C6+. Las ratas Wistar se dividieron aleatoriamente en grupos control, modelo de irradiación de iones pesados 12C6+ y grupos de dosis alta/media/baja de HQD. La tinción con HE evaluó los cambios patológicos del cerebro y el riñón. Se detectaron indicadores químicos de sangre periférica, así como factores inflamatorios y hormonas endocrinas. La apoptosis se midió con TUNEL. La expresión del antígeno nuclear de células en proliferación (PCNA) se determinó mediante PCR en tiempo real y transferencia Western blot. La irradiación indujo daños patológicos en los tejidos cerebrales y renales. Después de la irradiación, disminuyó el número de glóbulos blancos (WBC) y monocitos, y la expresión de interleucina (IL)-2, hormona liberadora de corticotropina (CRH) y PCNA. El daño estuvo acompañado por una mayor expresión de IL-1β, IL-6, corticosterona (CORT) y hormona adrenocorticotrópica (ACTH), así como un aumento de la apoptosis neuronal. Estas alteraciones fueron indicativas de efectos inducidos por la radiación. La administración de HQD atenuó el daño patológico a los tejidos cerebrales y renales, y aumentó el número de leucocitos y monocitos, así como la expresión de IL-2, CRH y PCNA. También disminuyó la expresión de IL-1β, IL-6, CORT y ACTH, así como la apoptosis neuronal. HQD exhibe mecanismos protectores contra los efectos externos inducidos por la radiación 12C6+. El mecanismo subyacente puede implicar la promoción de la producción de células sanguíneas periféricas, la inhibición de factores inflamatorios y la apoptosis y la regulación de hormonas endocrinas.

Comparison of coagulation function between adrenocorticotropic hormone independent Cushing syndrome and nonfunctional adrenal adenoma and its influence factors / 北京大学学报(医学版)

OBJECTIVE@#To investigate the coagulation function indicators and identify influence factors of hypercoagulability in patients with adrenocorticotropic hormone (ACTH) independent Cushing syndrome (CS).@*METHODS@#In our retrospective study, the electronic medical records system of Peking University First Hospital was searched for the patients diagnosed with ACTH independent CS on discharge from January 2014 to June 2019. Nonfunctional adrenal adenoma patients were chosen as control group and matched 1 ∶1 by body mass index (BMI), gender, and discharge date. Clinical features and coagulation function indicators were compared between the two groups.@*RESULTS@#In the study, 171 patients were included in each group. Compared with control group, activated partial thromboplastin time (APTT), and prothrombin time (PT) in ACTH independent CS group were significantly lower [(29.22±3.39) s vs. (31.86±3.63) s, P < 0.001; (29.22±3.39) s vs. (31.86±3.63) s, P < 0.001], and both D-dimer and fibrin degradation products (FDP) levels were significantly higher (P < 0.05). Percentage of APTT levels under the lower limit of reference range in the CS patients was significantly higher than that in nonfunctional group (21.6% vs. 3.5%, P < 0.001). Percentage of D-dimer levels over the upper limit of reference range in the CS patients was significantly higher than that in nonfunctional group (13.5% vs. 6.6%, P=0.041). There were three patients with deep venous thrombosis and one patient with pulmonary embolism in CS group, however none was in control group. The area under curve (AUC) of serum cortisol rhythm (8:00, 16:00 and 24:00) levels was negatively associated with the levels of PT (r=-0.315, P < 0.001) and APTT (r=-0.410, P < 0.001), and positively associated with FDP (r=0.303, P < 0.001) and D-dimer levels (r=0.258, P < 0.001). There were no differences in coagulation function indicators among different histopathologic subgroups (adrenocortical adenoma, adrenocortical hyperplasia, oncocytic adenoma, adrenocortical carcinoma). With Logistic regression analysis, the AUC of cortisol and glycosylated hemoglobin A1c (HbA1c) levels were independent risk factors for hypercoagulability in the ACTH independent CS patients (P < 0.05).@*CONCLUSION@#ACTH independent CS patients were more likely in hypercoagulable state compared with nonfunctional adrenal adenoma, especially in ACTH independent CS patients with higher levels of cortisol AUC and HbA1c. These patients should be paid attention to for the hypercoagulability and thrombosis risk.

Hypothalamic-Pituitary-Adrenal axis activity in SARS-CoV-2 infected noncritically ill hospitalized patients / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#This study determined the baseline hormonal levels of the hypothalamic-pituitary-adrenal axis and their associated factors in noncritically ill hospitalized patients with coronavirus disease 2019 (COVID-19).@*Methodology@#This cross-sectional observational study was carried out in 91 noncritical RT-PCR-confirmed COVID-19 patients (18-65 years) recruited consecutively from the COVID unit, of two tertiary care hospitals over a period of six months. After screening for exclusion criteria relevant history and physical examinations were done, and blood was drawn between 07:00 am to 09:00 am in a fasting state to measure serum cortisol and plasma adrenocorticotropic hormone (ACTH) by chemiluminescent microparticle immunoassay.@*Result@#Of 91 patients, 54, 26, and 11 had mild, moderate, and severe disease respectively. Median values of serum cortisol (p=0.057) and plasma ACTH (p=0.910) were statistically similar among the severity groups. Considering cortisol cut-off of 276 nmol/L (<10 μg/dL), the highest percent of adrenal insufficiency was present in severe (27.3%), followed by mild (25.9%) and least in moderate (3.8%) COVID-19 cases. Using the cortisol/ACTH ratio >15, only 6.6% had enough reserve.@*Conclusions@#The adrenocortical response was compromised in a significant percentage of noncritically ill hospitalized patients with COVID-19, which is unrelated to infection severity, with greater percentages present in severely infected cases.

Factors influencing the efficacy of initial adrenocorticotropic hormone therapy for infantile epileptic spasms syndrome / 中国当代儿科杂志

OBJECTIVES@#To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis.@*METHODS@#The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis.@*RESULTS@#ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05).@*CONCLUSIONS@#Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

Clinical application value of Huanglian Jiedu Pills in improving syndrome of excess heat and fire toxin based on phase Ⅱ clinical trial study on plasma ATP, 4-HNE, and ACTH levels / 中国中药杂志

A randomized, double-blind, placebo-controlled, multi-center phase Ⅱ clinical trial design was used in this study to recruit subjects who were in line with the syndrome of excess heat and fire toxin, and were diagnosed as recurrent oral ulcers, gingivitis, and acute pharyngitis. A total of 240 cases were included and randomly divided into a placebo group and a Huanglian Jiedu Pills group. The clinical efficacy of Huanglian Jiedu Pills in treating the syndrome of excess heat and fire toxin was evaluated by using the traditional Chinese medicine(TCM) syndrome scale. Enzyme-linked immunosorbent assay(ELISA) was used to determine and evaluate the levels of adenosine triphosphate(ATP), 4-hydroxynonenal(4-HNE), and adrenocorticotropic hormone(ACTH) in plasma of the two groups before and after administration and to predict their application value as clinical biomarkers. The results showed that the disappearance rate of main symptoms in the Huanglian Jiedu Pills group was 69.17%, and that in the placebo group was 50.83%. The comparison between the Huanglian Jiedu Pills group and the placebo group showed that 4-HNE before and after administration was statistically significant(P<0.05). The content of 4-HNE in the Huanglian Jiedu Pills group decreased significantly after administration(P<0.05), but that in the placebo group had no statistical significance and showed an upward trend. After administration, the content of ATP in both Huanglian Jiedu Pills group and placebo group decreased significantly(P<0.05), indicating that the energy metabolism disorder was significantly improved after administration of Huanglian Jiedu Pills and the body's self-healing ability also alleviated the increase in ATP level caused by the syndrome of excess heat and fire toxin to a certain extent. ACTH in both Huanglian Jiedu Pills group and placebo group decreased significantly after administration(P<0.05). It is concluded that Huanglian Jiedu Pills has a significant clinical effect, and can significantly improve the abnormal levels of ATP and 4-HNE in plasma caused by the syndrome of excess heat and fire toxin, which are speculated to be the effective clinical biomarkers for Huanglian Jiedu Pills to treat the syndrome of excess heat and fire toxin.

Vigabatrina comparado con hormona adrenocorticotrópica para el tratamiento de espasmos infantiles y Síndrome de West / Vigabatrin compared with adrenocorticotropic hormone for the treatment of infantile spasms and West Syndrome

OBJETIVO: Determinar los riesgos y beneficios del uso de vigabatrina comparada con hormona adrenocorticotrópica (ACTH) para el tratamiento de espasmos infantiles. MÉTODO: Se realizó una búsqueda en Epistemonikos. Se extrajeron datos desde las revisiones identificadas. Se realizó un metaanálisis a partir de estudios primarios y se utilizó el método GRADE para la presentación de resultados. RESULTADOS: Se identificaron nueve revisiones sistemáticas. Se observó que el uso de vigabatrina en comparación con ACTH disminuye la resolución de espasmos (RR 0,8, IC 95% 0,65 - 0,98) y podría disminuir la resolución de hipsarritmia (RR 0,71, IC 95% 0,48 - 1,05). No fue posible determinar si el uso de vigabatrina disminuye el riesgo de desarrollar efectos adversos (RR 0,75, IC 95% 0,23 - 2,45) por certeza de evidencia muy baja. CONCLUSIONES: La evidencia parece inclinarse a favor del uso de ACTH. Sin embargo debe considerarse la necesidad de nuevas investigaciones para esclarecer su seguridad.

OBJECTIVE: To determine the risks and benefits of the use of vigabatrin compared to ACTH for the treatment of infantile spasms. METHOD: A search in Epistemonikos was performed. Data were extracted from the identified reviews. A meta-analysis was performed from primary studies and the GRADE method was used to present the results. RESULTS: Nine systematic reviews were identified. Vigabatrin use compared to ACTH was found to decrease resolution of spasms (RR 0.8, 95% CI 0.65 - 0.98) and might decrease resolution of hypsarrhythmia (RR 0.71, 95% CI 0 .48 - 1.05). It was not possible to determine whether the use of vigabatrin reduces the risk of developing adverse effects (RR 0.75, 95% CI 0.23 - 2.45) due to very low certainty of evidence. CONCLUSIONS: The evidence seems to lean in favor of the use of ACTH. However, the need for new research should be considered to clarify its safety.

Se obtuvieron 1819 resultados, de los cuales se seleccionaron 20 artículos con mayor validez y replicabilidad en el medio para establecer un protocolo unificado de actuación. CONCLUSIÓN. El objetivo de la terapia es el tratamiento de la hipotensión y reversión de las anomalías electrolíticas y de la deficiencia de cortisol. Se deben infundir por vía intravenosa grandes volúmenes (1 a 3 litros) de solución salina al 0,9% o dextrosa al 5% en solución salina al 0,9% y la administración de hidrocortisona (bolo de 100 mg), seguido de 50 mg cada 6 horas (o 200 mg / 24 horas como infusión continua durante las primeras 24 horas). Si no se dispone de hidrocortisona, las alternativas incluyen prednisolona, prednisona y dexametasona.

INTRODUCTION. Adrenal crisis refers to acute adrenal insufficiency; which is a disorder in which the adrenal cortex does not produce enough steroid hormones (especially cortisol) to meet the body's demands, according to the pathophysiological mechanism it can be classified as primary, secondary and tertiary, being more common in patients with primary adrenal insufficiency. It is a life-threatening emergency that requires immediate treatment. OBJECTIVE. To establish a strategy for the prevention and treatment of adrenal crisis, as well as the ideal pharmacotherapy and its valid alternatives. MATERIAL AND METHODS. A literature review was performed in several highly scientific virtual journals such as Cochrane Library, Cochrane Systematic Reviews Database, MEDLINE through PubMed and ClinicalTrial.gov. Systematic reviews with or without meta-analysis, clinical trials and expert recommendations related to prevention and treatment of adrenal crisis in general were selected. RESULTS. A total of 1819 results were obtained, from which 20 articles with greater validity and replicability in the setting were selected to establish a unified protocol for action. CONCLUSIONS. The aim of therapy is the treatment of hypotension and reversal of electrolyte abnormalities and cortisol deficiency. Large volumes (1 to 3 liters) of 0.9% saline or 5% dextrose in 0.9% saline and administration of hydrocortisone (100 mg bolus), followed by 50 mg every 6 hours (or 200 mg / 24 hours as a continuous infusion for the first 24 hours) should be infused intravenously. If hydrocortisone is not available, alternatives include prednisolone, prednisone, and dexamethasone.

Cushing's syndrome due to ectopic adrenocorticotropin secretion by a parotid carcinoma

SUMMARY We report a rare case of Cushing's syndrome in a 37-year-old female who initially presented with localized acinic cell carcinoma of the parotid gland. In January 2014, she underwent a right parotidectomy with facial nerve preservation and adjuvant radiotherapy. In August 2018, she presented a histologically-proven local regional relapse. The patient was considered for salvage surgery with facial nerve sacrifice and remained with no evidence of disease. One year later the patient developed pulmonary dissemination and started to gain weight and developed facial plethora and acne on the face and upper trunk. In a physical examination, the patient presented moon face, buffalo hump, acne and stage 2 hypertension. Biochemical evaluation confirmed ACTH-dependent Cushing's syndrome. IHC for ACTH in the lung biopsy revealed strong positive staining for ACTH confirming a diagnosis of ectopic ACTH secretion by a metastatic parotid acinic cell carcinoma. Ketoconazole (600 mg/d) was started to treat the CS. In addition, as chemotherapy was initiated to treat the metastatic disease. After the fifth cycle of chemotherapy, ketoconazole was suspended and the patient remained in remission of CS for four months, when CS recurred. A unique feature of this case is related to the clinical CS relapse associated with disease progression, which needed prompt treatment with ketoconazole, resulting in a significant improvement in the patient's condition. Although rare, should be attentive for possible CS features in patients with high-grade salivary gland carcinomas, since the diagnosis of ectopic secretion of ACTH may significantly impact their management and outcomes.

Efficacy of adrenocorticotropic hormone in children with frequently relapsing or steroid-dependent nephrotic syndrome / 中华儿科杂志

Objective: To investigate the efficacy and safety of adrenocorticotropic hormone (ACTH) in children with frequently relapsing or steroid-dependent nephrotic syndrome. Methods: The clinical data of 38 children with frequently relapsing or steroid-dependent nephrotic syndrome who were admitted to the Department of Nephrology, the Children Hospital, Zhejiang University School of Medicine from January 2015 to December 2020 were retrospectively analyzed. The general information, clinical manifestations, laboratory data of the children and follow-up (till 12 months after treatment) were collected. The patients were divided into ACTH group and Glucocorticoid (GC) group according to treatment plan. Cumulative remission, average recurrence rate, GC dosage, height and weight change and peripheral blood CD19+B lymphocyte count were compared between the two groups to evaluate the efficacy and adverse reactions of ACTH. Fisher's exact test, t test or rank sum test was used for comparison between groups. Results: Among the 38 patients, 28 were male and 10 were female, aged 84 (24, 180) months; 19 were in ACTH group and 19 were in GC group. The cumulative remission rate of 12 months in ACTH group was higher than that in GC group (9/19 vs. 2/19,χ²=6.81,P=0.009), the average recurrence rate was lower than that in GC group ((0.7±0.8) vs. (1.7±1.1) times, t=-3.27, P=0.011), and the average dosage of GC was lower than that in GC group ((0.27±0.16) vs. (0.51±0.27) mg/(kg·d), t=-3.21, P=0.014). The increase in height was higher than that in the GC group (4 (3,5) vs. 3 (2, 3) cm/year, Z=2.58, P=0.010), and the peripheral blood CD19+B lymphocyte count was lower than that in the GC group ((223±149)×106 vs. (410±213)×106/L,t=-3.35, P=0.009). In safety, 19 cases had transient decreased urine volume, 7 cases had hyperglycemia, and 3 cases had hypertension during the infusion of ACTH, which could be relieved after drug withdrawal. Conclusion: ACTH has a better effect on children with frequently relapsing or steroid-dependent nephrotic syndrome, which can improve cumulative sustained remission rate, lower relapses rate and decrease the dosage of GC, with good safety.

Effects of comprehensive treatment of infected wounds in patients with iatrogenic Cushing's syndrome / 中华烧伤杂志

Objective: To investigate the characteristics and comprehensive treatment of infected wounds in patients with iatrogenic Cushing's syndrome. Methods: A retrospective observational study was conducted. From May 2012 to December 2021, the data of 19 patients with iatrogenic Cushing's syndrome discharged from the Department of Burns and Plastic Surgery of the First Affiliated Hospital of Guangxi Medical University were collected, including 8 males and 11 females, aged 28-71 (56±11) years, with 12 cases of infected acute wounds and 7 cases of infected chronic wounds. The lesions were located in the limbs, perianal, and sacrococcygeal regions, with original infection ranging from 9 cm×5 cm to 85 cm×45 cm. After admission, the patients were performed with multidisciplinary assisted diagnosis and treatment, and the wounds were treated with debridement and vacuum sealing drainage, according to the size, severity of infection, suture tension, and bone and tendon tissue exposure of wounds, direct suture or autologous skin and/or artificial dermis and/or autologous tissue flap transplantation was selected for wound repair. The levels of cortisol and adrenocorticotropic hormone (ACTH) of patients at 8:00, 16:00, and 24:00 within 24 h after admission were counted. After admission, the number of operations, wound repair methods, and wound and skin/flap donor site healing of patients were recorded. During follow-up, the wounds were observed for recurrent infection. Results: The cortisol levels of 16 patients at 8:00, 16:00, and 24:00 within 24 h after admission were (130±54), (80±16), and (109±39) nmol/L, respectively, and ACTH levels were (7.2±2.8), (4.1±1.8), and (6.0±3.0) pg/mL, respectively; and the other 3 patients had no such statistical results. After admission, the number of surgical operation for patients was 3.4±0.9. The following methods were used for wound repair, including direct suturing in 4 cases and autologous skin and/or artificial dermis grafting in 9 cases, of which 2 cases underwent stage Ⅱ autologous skin grafting after artificial dermis grafting in stage Ⅰ, and 6 cases had pedicled retrograde island flap+autologous skin grafting. The wound healing was observed, showing that all directly sutured wounds healed well; the wounds in 6 cases of autologous skin and/or artificial dermis grafting healed well, and the wounds in 3 cases also healed well after the secondary skin grafting; the flaps in 4 cases survived well with the wounds in 2 cases with distal perforators flap arteries circumfluence obstacle of posterior leg healed after stage Ⅱ debridement and autologous skin grafting. The healing status of skin/flap donor sites was followed showing that the donor sites of medium-thickness skin grafts in the thigh of 4 cases were well healed after transplanted with autologous split-thickness grafts from scalp; the donor sites of medium-thickness skin grafts in 3 cases did not undergo split-thickness skin grafting, of which 2 cases had poor healing but healed well after secondary skin grafting 2 weeks after surgery; the donor sites of split-thickness skin grafts in the head of 2 patients healed well; and all donor sites of flaps healed well after autologous skin grafting. During follow-up of more than half a year, 3 gout patients were hospitalized again for surgical treatment due to gout stone rupture, 4 patients were hospitalized again for surgical treatment due to infection, and no recurrent infection was found in the rest of patients. Conclusions: The infected wounds in patients with iatrogenic Cushing's syndrome have poor ability to regenerate and are prone to repeated infection. Local wound treatment together with multidisciplinary comprehensive treatment should be performed to control infection and close wounds in a timely manner, so as to maximize the benefits of patients.

Yixin Ningshen Tablet Alleviates Comorbidity of Myocardial Infarction and Depression by Enhancing Myocardial Energy Metabolism and Increasing Availability of Monoamine Neurotransmitter / 中国结合医学杂志

OBJECTIVE@#To investigate the therapeutic effect of Yixin Ningshen Tablet (YXNS) on comorbidity of myocardial infarction (MI) and depression in rats and explore the underlying mechanism.@*METHODS@#The Sprague-Dawley rats were randomly divided into 5 groups with 7 rats in each group according to their weights, including control, model, fluoxetine (FLXT, 10 mg/kg), low-dose YXNS (LYXNS, 100 mg/kg), and high-dose YXNS (HYXNS, 300 mg/kg) groups. All rats were pretreated with corresponding drugs for 12 weeks. The rat model of MI and depression was constructed by ligation of left anterior descending coronary artery and chronic mild stress stimulation. The echocardiography, sucrose preference test, open field test, and forced swim test were performed. Myocardial infarction (MI) area and myocardial apoptosis was also detected. Serum levels of interleukin (IL)-6, IL-1β, tumor necrosis factor-α (TNF-α), 5-hydroxytryptamine (5-HT), adrenocorticotrophic hormone (ACTH), corticosterone (CORT), and norepinephrine (NE) were determined by enzyme linked immunosorbent assay. The proteins of adenosine 5'-monophosphate -activated protein kinase (AMPK), p-AMPK, peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), and nuclear respiratory factor 1 (NRF1) in heart were detected by Western blot analysis. The expression levels of TNF-α, IL-6, indoleamine 2,3-dioxygenase (IDO1), kynurenine 3-monooxygenase (KMO), and kynureninase (KYNU) in hippocampus were detected by real-time quantitative polymerase chain reaction.@*RESULTS@#Compared with the model group, the cardiac function of rats treated with YXNS improved significantly (P<0.01). Meanwhile, YXNS effectively reduced MI size and cardiomyocytes apoptosis of rats (P<0.01 or P<0.05), promoted AMPK phosphorylation, and increased PGC-1α protein expression (P<0.01 or P<0.05). HYXNS significantly increased locomotor activity of rats, decreased the levels of TNF-α, IL-6 and IL-1β, and increased the serum levels of 5-HT, NE, ACTH, and CORT (all P<0.05). Moreover, HYXNS decreased the mRNA expressions of IDO1, KMO and KYNU (P<0.05).@*CONCLUSIONS@#YXNS can relieve MI by enhancing myocardial energy metabolism. Meanwhile, YXNS can alleviate depression by resisting inflammation and increasing availability of monoamine neurotransmitters. It may be used as a potential drug to treat comorbidity of MI and depression.

Effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen: a prospective randomized controlled study / 中国当代儿科杂志

OBJECTIVES@#To study the effect of somatostatin on postoperative gastrointestinal function and stress level in children with acute abdomen.@*METHODS@#A total of 102 children with acute abdomen who underwent surgery in Xuzhou Children's Hospital from August 2019 to June 2021 were enrolled as subjects and were randomly divided into an observation group and a control group, with 51 children in each group. The children in the control group were given conventional treatment such as hemostasis and anti-infective therapy after surgery, and those in the observation group were given somatostatin in addition to conventional treatment. Peripheral blood samples were collected from both groups before surgery and on days 1 and 5 after surgery. The two groups were compared in terms of the serum levels of endothelin-1 (ET-1), adrenocorticotropic hormone (ACTH), cortisol, gastrin, and motilin, postoperative recovery, and the incidence rate of complications.@*RESULTS@#There was no significant difference in the serum levels of ET-1, ACTH, cortisol, gastrin, and motilin between the two groups before surgery (P>0.05). Compared with the control group, the observation group had significantly lower serum levels of ET-1, ACTH, and cortisol on days 1 and 5 after surgery (P<0.05) and significantly higher levels of motilin and gastrin on day 5 after surgery (P<0.05). Compared with the control group, the observation group had significantly shorter time to first passage of flatus, first bowel sounds, and first defecation after surgery, as well as a significantly shorter length of hospital stay (P<0.05). The incidence rate of complications in the observation group was significantly lower than that in the control group (6% vs 24%, P<0.05).@*CONCLUSIONS@#In children with acute abdomen, somatostatin can significantly reduce postoperative stress response, improve gastrointestinal function, and reduce the incidence rate of complications, thereby helping to achieve a good prognosis.

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases / 北京大学学报(医学版)

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases SUMMARY Programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) have been widely used in lung cancer treatment, but their immune-related adverse events (irAEs) require intensive attention. Pituitary irAEs, including hypophysitis and hypopituitarism, are commonly induced by cytotoxic T lymphocyte antigen 4 inhibitors, but rarely by PD-1/PD-L1 inhibitors. Isolated adrenocorticotropic hormone(ACTH) deficiency (IAD) is a special subtype of pituitary irAEs, without any other pituitary hormone dysfunction, and with no enlargement of pituitary gland, either. Here, we described three patients with advanced lung cancer who developed IAD and other irAEs, after PD-1 inhibitor treatment. Case 1 was a 68-year-old male diagnosed with metastatic lung adenocarcinoma with high expression of PD-L1. He was treated with pembrolizumab monotherapy, and developed immune-related hepatitis, which was cured by high-dose methylprednisolone [0.5-1.0 mg/(kg·d)]. Eleven months later, the patient was diagnosed with primary gastric adenocarcinoma, and was treated with apatinib, in addition to pembrolizumab. After 17 doses of pembrolizumab, he developed severe nausea and asthenia, when methylprednisolone had been stopped for 10 months. His blood tests showed severe hyponatremia (121 mmol/L, reference 137-147 mmol/L, the same below), low levels of 8:00 a.m. cortisol (< 1 μg/dL, reference 5-25 μg/dL, the same below) and ACTH (2.2 ng/L, reference 7.2-63.3 ng/L, the same below), and normal thyroid function, sex hormone and prolactin. Meanwhile, both his lung cancer and gastric cancer remained under good control. Case 2 was a 66-year-old male with metastatic lung adenocarcinoma, who was treated with a new PD-1 inhibitor, HX008, combined with chemotherapy (clinical trial number: CTR20202387). After 5 months of treatment (7 doses in total), his cancer exhibited partial response, but his nausea and vomiting suddenly exacerbated, with mild dyspnea and weakness in his lower limbs. His blood tests showed mild hyponatremia (135 mmol/L), low levels of 8:00 a.m. cortisol (4.3 μg/dL) and ACTH (1.5 ng/L), and normal thyroid function. His thoracic computed tomography revealed moderate immune-related pneumonitis simultaneously. Case 3 was a 63-year-old male with locally advanced squamous cell carcinoma. He was treated with first-line sintilimab combined with chemotherapy, which resulted in partial response, with mild immune-related rash. His cancer progressed after 5 cycles of treatment, and sintilimab was discontinued. Six months later, he developed asymptomatic hypoadrenocorticism, with low level of cortisol (1.5 μg/dL) at 8:00 a.m. and unresponsive ACTH (8.0 ng/L). After being rechallenged with another PD-1 inhibitor, teslelizumab, combined with chemotherapy, he had pulmonary infection, persistent low-grade fever, moderate asthenia, and severe hyponatremia (116 mmol/L). Meanwhile, his blood levels of 8:00 a.m. cortisol and ACTH were 3.1 μg/dL and 7.2 ng/L, respectively, with normal thyroid function, sex hormone and prolactin. All of the three patients had no headache or visual disturbance. Their pituitary magnetic resonance image showed no pituitary enlargement or stalk thickening, and no dynamic changes. They were all on hormone replacement therapy (HRT) with prednisone (2.5-5.0 mg/d), and resumed the PD-1 inhibitor treatment when symptoms relieved. In particular, Case 2 started with high-dose prednisone [1 mg/(kg·d)] because of simultaneous immune-related pneumonitis, and then tapered it to the HRT dose. His cortisol and ACTH levels returned to and stayed normal. However, the other two patients' hypopituitarism did not recover. In summary, these cases demonstrated that the pituitary irAEs induced by PD-1 inhibitors could present as IAD, with a large time span of onset, non-specific clinical presentation, and different recovery patterns. Clinicians should monitor patients' pituitary hormone regularly, during and at least 6 months after PD-1 inhibitor treatment, especially in patients with good oncological response to the treatment.

Effects of Chronic Restraint Stress on Apoptosis of Amygdala Cells in Rats / 法医学杂志

OBJECTIVES@#To explore the damage effects of chronic restraint stress (CRS) on amygdala cells through the rat CRS model.@*METHODS@#The rat CRS model was established, and the changes in body weight and adrenal mass in control group and CRS group were monitored at 1 d, 7 d, 14 d and 21 d. The behavior changes were evaluated by the percentage of retention time of open arms and open arm entries using the elevated plus maze (EPM). ELISA was used to detect the concentrations of rat's corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and cortisol. The changes of expression of glucocorticoid receptor (GR) and glial fibrillary acidic protein (GFAP) in amygdala were determined by immunohistochemistry and Western blotting. Ultrastructure changes of glial cell were observed by transmission electron microscopy. The apoptosis rate of amygdala was measured by flow cytometry.@*RESULTS@#Compared with the control group at the same time points, body weight of CRS 1 d, 7 d, 14 d and 21 d groups increased slowly, but adrenal mass increased significantly; the serum level of CRH, cortisol and ACTH increased significantly at 7 d, 14 d and 21 d respectively; the expression of GR in amygdala was increased while that of GFAP was decreased; EPM test suggested that the percentage of retention time of open arms and open arm entries decreased significantly after 14 d. The CRS group showed different degrees of glial cell damage in amygdala, and the apoptosis rate of glial cell was significantly increased in 21 d group.@*CONCLUSIONS@#This study successfully established a CRS model in rats, and anxiety-like behavioral changes in model rats may be caused by apoptosis of amygdala astrocytes.

Cyclic ACTH-secreting thymic carcinoid: a case report and review of the literature

SUMMARY Cyclic Cushing's syndrome (CS) due to thymic carcinoid is a rare disorder. We report a case of cyclic CS due to ectopic adrenocorticotropic hormone (ACTH)-secreting atypical thymic carcinoid tumor and reviewed similar cases published in the literature. Our patient had hypercortisolemia lasting approximately one month, followed by normal cortisol secretion, with relapse one year later. Histopathology revealed an atypical ACTH-positive thymic carcinoid. Ectopic CS can be derived from atypical thymic carcinoids, which can be aggressive tumors with early relapse, suggesting that this type of tumor probably needs aggressive treatment.

Comparison of a combination test (1 µg ACTH test plus glucagon test) versus 1 µg ACTH test and glucagon test in the evaluation of the hypothalamic-pituitary-adrenal axis in patients with pituitary disorders

ABSTRACT Objective To investigate whether a combination of the low-dose (1 µg) adrenocorticotropin (ACTH) stimulation test and glucagon stimulation test (GST) could overcome the problem of equivocal results with the GST or ACTH test alone in patients with pituitary disorders. Subjects and methods The study included 41 adult patients with pituitary disorders and 20 healthy subjects who underwent evaluation of cortisol response to ACTH, GST, and a combination of both tests. Blood samples for cortisol measurement were obtained at baseline and 30, 60, 90, and 120 minutes after intravenous administration of ACTH 1 μg and 90, 120, 150, 180, 210, and 240 minutes after subcutaneous injection of glucagon 1 mg. The combination test was performed by injecting ACTH 1 µg at the 180-minute time point of the GST, with blood samples for cortisol measurement obtained at 210 and 240 minutes. Results Overall, 28 patients with normal cortisol response to both tests also had a normal cortisol response to the combination test. Ten patients with adrenal insufficiency in both tests also had adrenal insufficiency in the combination test, including a patient who had a peak cortisol value of 12.4 µg/dL (which is the cutoff value for the combination test). Two patients with adrenal insufficiency in the ACTH stimulation test and one patient with adrenal insufficiency in the GST had normal cortisol responses to the combination test. Conclusion By using an appropriate cutoff value, the combination test may offer additional information in patients with equivocal results in the GST and ACTH stimulation test.

Adrenal function evaluation in critically ill dogs with low doses of synthetic ACTH / Avaliação da função adrenal em cães portadores de doenças críticas com baixa dose de ACTH sintético

The hypothalamus-pituitary-adrenal axis function may be impaired in patients with critical illnesses, especially cases of sepsis, named critical illness-related corticosteroid insufficiency (CIRCI). This study examined the function of the hypothalamic-pituitary-adrenal axis in normal dogs (n = 10) and dogs with critical diseases (n = 16), through determinations of endogenous ACTH (adrenocorticotropic hormone), basal cortisol and cortisol after stimulation in low doses of synthetic ACTH (1.0µg/kg/IV). The stimulation test with ACTH dose tested was verified as effective for evaluation of adrenal function in healthy and sick dogs. Ill dogs differed from healthy dogs by presenting higher basal cortisol values. Eight sick dogs presented a decrease in endogenous ACTH, basal cortisol, or Δ-cortisol. No significant differences were found between the control groups and critically ill dogs for the values of endogenous ACTH, cortisol after stimulation or Δ-cortisol. We concluded that the stimulation test with low-dose ACTH was effective for evaluation of adrenal function, as well as the fact that a considerable portion of critically ill dogs studied here, especially with sepsis, had evidence of inadequate corticosteroid response to stress.(AU)

A função do eixo hipotálamo-hipófise-adrenal pode estar comprometida em pacientes com doenças críticas, em especial casos de sepse, sendo nomeada de Insuficiência Corticosteroide Relacionada à Doença Crítica (ICRDC). O presente trabalho analisou a função do eixo hipotálamo-hipófise-adrenal em cães normais (n=10) e cães portadores de doenças críticas (n=16), por meio de determinações de ACTH (hormônio adrenocorticotrófico) endógeno, de cortisol basal e de cortisol após estímulo com baixa dose de ACTH sintético (1,0µg/kg/IV). Constatou-se que o teste de estimulação com ACTH na dose testada se mostrou eficaz para avaliação da função adrenal em cães sadios e doentes. Os cães doentes diferiram dos sadios ao apresentar valores maiores de cortisol basal. Oito cães doentes apresentaram diminuição do ACTH endógeno, do cortisol basal ou do Δ-cortisol. Não foram encontradas diferenças significativas entre os grupos Controle e Criticamente enfermos para os valores de ACTH endógeno, cortisol após estimulação ou Δ-cortisol. Concluiu-se que o teste de estimulação com baixa dose de ACTH mostrou-se eficaz para avaliação da função adrenal, assim como, uma parcela considerável da população de cães críticos aqui estudados, em especial com sepse, apresentaram evidências de resposta corticosteroide inadequada frente ao estresse.(AU)

Efectos endocrinológicos tardíos del tratamiento oncológico en supervivientes de meduloblastoma / Endocrinological late effects of oncologic treatment on survivors of medulloblastoma

INTRODUCCIÓN: La radioterapia, quimioterapia y la cirugía empleada en el tratamiento de los tumores cerebrales tienen efectos en el eje hipotálamo-hipofisario y pueden resultar en disfunción endocrina hasta en el 96% de los casos. PACIENTES Y MÉTODO: Estudio retrospectivo y descriptivo en pacientes diagnos ticados de meduloblastoma sometidos a tratamiento con quimio y radioterapia en los últimos 20 años en un hospital terciario. Se analizan variables edad, sexo, peso, talla, índice de masa corporal (IMC) al final del seguimiento, estadio de maduración sexual, niveles séricos de TSH y T4 libre, ACTH/cortisol e IGF-1, FSH, LH, estradiol, testosterona, perfil lipídico (colesterol total) y prueba de función dinámica de hormona de crecimiento. RESULTADOS: Muestra total de 23 pacientes. El déficit de hormona de crecimiento es la secuela más frecuente (82 %) seguido de disfunción ti roidea (44,8%) y disfunción puberal (24,1%). Solo se diagnosticó un caso de diabetes insípida y 2 casos de déficit de corticotrofina. CONCLUSIONES: El seguimiento a largo plazo de los supervivientes de meduloblastoma tratados con quimio y radioterapia revela una prevalencia muy alta de disfun ción endocrina, particularmente de deficiencia de hormona del crecimiento y de hipotiroidismo. Creemos oportuna la monitorización y el seguimiento a largo plazo de estos pacientes con el fin de garantizar un manejo terapéutico adecuado de aquellas disfunciones tratables.

INTRODUCTION: Radiation therapy, chemotherapy, and surgery used to treat brain tumors have effects on the hy pothalamic-pituitary-adrenal axis and can result in endocrine dysfunction in up to 96% of cases. PATIENTS Y METHOD: Retrospective and descriptive study in patients diagnosed with medulloblasto ma who underwent treatment with chemo and radiotherapy in the last 20 years in a tertiary hospital. The variables analyzed were age, sex, weight, height, body mass index (BMI) at the end of follow-up, sexual maturity stage, serum levels of TSH and free T4, ACTH/cortisol and IGF-1, FSH, LH, estradiol, testosterone, lipid profile (total cholesterol), and growth hormone dynamic function test. RESULTS: Total sample of 23 patients. Growth hormone deficiency is the most frequent sequelae (82%) fo llowed by thyroid dysfunction (44.8%), and disorders of puberty (24.1%). Only one case of diabetes insipidus and two cases of corticotropin deficiency were diagnosed. CONCLUSIONS: Long-term follow- up of medulloblastoma survivors treated with chemo and radiotherapy reveals a very high prevalence of endocrine dysfunction, especially growth hormone deficiency and hypothyroidism. We believe that monitoring and long-term follow-up of these patients is necessary in order to ensure adequate therapeutic management of those treatable dysfunctions.

Limited significance of repeated long-term radiological and hormonal examination in nonfunctioning adrenal incidentalomas

ABSTRACT Purpose: The purposes of the present study were to evaluate growth rate of nonfunctioning adrenal incidentalomas (AIs) and their development to hormonal hypersecretion on follow-up. Materials and methods: A retrospective study was conducted from the electronic medical records. A total of 314 patients were diagnosed with adrenal tumors between 2000 and 2016. After excluding patients who had overt adrenal endocrine disorders or whose adrenal tumors were clinically diagnosed as metastatic malignancies, we investigated 108 patients with nonfunctioning AIs including characteristics, the treatment, the way of follow-up and pathology. Results: Fifteen patients received immediate adrenalectomy because of the initial tumor size or patient's preference. Pathological examination revealed malignancy in 2 patients. In the remaining 93 patients, radiological examinations were performed periodically. Tumor enlargement of ≥ 1.0cm was observed in 8.6% of the patients who were followed up as nonfunctioning AIs with a median follow-up period of 61.5 months (range: 4-192). Eleven patients underwent adrenalectomy. On the pathological examinations, all of the tumors, which showed a size increase, were diagnosed as benign tumors. Regarding the followed up patients without adrenalectomy, only 2.4% of the patients had tumor enlargement during the prolonged follow-up. Furthermore, none of the patients developed hormonal hypersecretion or clinical signs such as obesity, glucose intolerance or poorly controlled hypertension. Conclusions: Tumor enlargement of AIs did not correlate with malignancy. The value of repeat radiological and hormonal examinations may be limited in the long-term follow-up of patients whose AIs are not enlarged.
