ABSTRACT
OBJECTIVE: To summarize findings from a case of adrenocortical hemorrhage following tetracosactide injection during ACTH stimulation testing for monitoring of trilostane therapy in a dog. ANIMAL: A 12-year old neutered male dog with adrenal-dependent hypercortisolism. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: 4 hours after ACTH stimulation testing, the patient developed vomiting, lethargy, and abdominal pain. Abdominal ultrasound was performed before and after an ACTH stimulation test. Following ACTH stimulation testing, there was progressive bilateral adrenal enlargement and free abdominal fluid had developed. This was considered to be caused by adrenocortical inflammation and hemorrhage secondary to the synthetic ACTH analog, tetracosactide, used during stimulation testing. A resting cortisol performed 5 hours after tetracosactide injection was not consistent with iatrogenic hypoadrenocorticism. TREATMENT AND OUTCOME: The patient was managed with analgesia, IV fluids, and corticosteroids and made a full recovery. CLINICAL RELEVANCE: To the authors' knowledge, this was the first reported case of adrenocortical hemorrhage following administration of a synthetic ACTH analog in a dog. This should be considered as a rare potential complication of ACTH stimulation testing.

OBJECTIVE: To report a prospectively planned analysis of two randomised controlled trials with embedded comparisons of prednisolone versus tetracosactide depot for the treatment of infantile epileptic spasms syndrome (IESS). METHODS: Individual patient data from patients randomly allocated to prednisolone or tetracosactide depot were analysed from two trials (UKISS, ICISS). The comparison was embedded within trials in which some patients also received vigabatrin but only patients receiving monotherapy with randomly allocated hormonal treatments are included in this analysis. The main outcome was cessation of spasms (Days 13-14 after randomisation). Lead time to treatment and underlying aetiology were taken into account. Cessation of spasms on Days 14-42 inclusive, electroclinical response (EEG Day 14), plus developmental and epilepsy outcomes (at 14 months in UKISS and 18 months in ICISS) are also reported. Minimum treatment was prednisolone 40 mg per day for two weeks or tetracosactide depot 0·5 mg IM on alternate days for two weeks, all followed by a reducing dose of prednisolone over two weeks. RESULTS: 126 infants were included in this study. On tetracosactide depot, 47 of 62 (76%) were free of spasms on Days 13-14 compared to 43 of 64 (67%) on prednisolone (difference 9%, 95% CI -7·2% to +25·2%, chi square 1·15, p = 0·28). For Day 14-42 cessation of spasms, on tetracosactide depot, 41 of 61 (67%) were free of spasms compared to 35 of 62 (56%) on prednisolone (difference 11%, 95% CI -6·4% to +28·4%, chi square 1·51, p = 0·22). There was no significant difference in mean VABS score between infants who received prednisolone compared with those who received tetracosactide depot (74·8 (SD 18·3) versus 78·0 (SD 20·2) t = -0·91 p = 0·36). The proportion with ongoing epilepsy at the time of developmental assessment was 20 of 61 (33%) in the tetracosactide group compared with 26 out of 63 (41%) in the prednisolone group (difference 8%, 95% CI -9·2% to +25·2%, Chi [2] 0·95, p = 0·33). SIGNIFICANCE: With hormone monotherapy, either prednisolone or tetracosactide depot may be recommended for infantile epileptic spasms syndrome.

BACKGROUND: Adrenal insufficiency can result in significant patient morbidity and mortality, but due to the range of symptoms and variable clinical course and etiologies, it can be a challenging condition to diagnose and manage. OBJECTIVE: This narrative review will discuss the evaluation of an adult patient at risk for a new diagnosis of adrenal insufficiency and the management of a patient with known or suspected adrenal insufficiency. DISCUSSION: A new presentation of adrenal insufficiency can range from nonspecific, minor symptoms including fatigue, to a life-threatening adrenal crisis with hemodynamic instability. Due to the variety of signs and symptoms, the diagnosis is often missed. Those with known adrenal insufficiency are at risk for adrenal crisis, which may occur due to a variety of triggers. Initial evaluation includes assessment for the underlying etiology or concomitant condition, laboratory analysis, and imaging, when clinically indicated. Although not necessary for evaluation in the emergency department setting, the diagnosis is confirmed by specific testing such as the cosyntropin stimulation test. The mainstay of treatment in adrenal crisis is hydrocortisone, intravenous fluid, glucose repletion, and treatment of the underlying acute trigger. CONCLUSIONS: Emergency clinicians must be prepared to recognize, evaluate, and manage those with known or suspected adrenal insufficiency or adrenal crisis.

OBJECTIVES: To examine adrenal cortex reserve in patients with rheumatic and musculoskeletal diseases (RMD) who relapse upon tapering of low glucocorticoid dose, despite concomitant treatment with disease-modifying anti-rheumatic drugs (DMARDs). METHODS: A morning standard dose of 250 mcg tetracosactide (Synacthen test) was given in 25 consecutive patients (13 rheumatoid arthritis, 2 psoriatic arthritis, 5 systemic lupus erythematosus, 2 dermatomyositis, 1 systemic sclerosis, 2 temporal arteritis) at the time of relapse upon small reductions (1-2 mg daily) of low prednisolone dose (<7.5 mg daily), while being on stable concomitant treatment with methotrexate, leflunomide, hydroxychloroquine, azathioprine, mycophenolate, tofacitinib, belimumab, anti-TNF, anti-IL-6 or anti-IL-1 regimens (n=14; 3; 9; 1; 2; 1; 1; 5; 2; 1, respectively). Sex-matched apparently healthy individuals (n=45) served as controls. RESULTS: Baseline cortisol levels and time-integrated cortisol response to tetracosactide were lower in patients than controls (12.01±4.47 vs. 15.63±4.16 mcg/dl, p=0.001, and 1050±286 vs. 1284±182, p<0.001, respectively). No significant associations were observed between the cortisol response to tetracosactide and age, duration of disease or glucocorticoid treatment. An abnormal Synacthen test, indicative of adrenal insufficiency, presumably secondary to chronic glucocorticoid administration, was noted in 5/25 patients. The remaining 20 patients (80%) had normal Synacthen test demonstrating, however, lower cortisol response than controls, independently of age (ß-coefficient=-0.373, p=0.033). CONCLUSIONS: Patients with RMD in remission under DMARDs who relapse upon concomitant low glucocorticoid dose tapering should be tested for iatrogenic adrenal insufficiency. Whether a marginally normal Synacthen test should discourage further attempts to withdraw glucocorticoid treatment in these patients warrants further investigation.

Objective: In a randomized trial, we aimed to evaluate the efficacy of cosyntropin injectable suspension, 1â mg/mL, compared to vigabatrin for infantile spasms syndrome. An additional arm was included to assess the efficacy of combination therapy (cosyntropin and vigabatrin) compared with cosyntropin monotherapy. Methods: Children (2 months to 2 years) with new-onset infantile spasms syndrome and hypsarhythmia were randomized into 3 arms: cosyntropin, vigabatrin, and cosyntropin and vigabatrin combined. Daily seizures and adverse events were recorded, and EEG was repeated at day 14 to assess for resolution of hypsarhythmia. The primary outcome measure was the composite of resolution of hypsarhythmia and absence of clinical spasms at day 14. Fisher exact test was used to compare outcomes. Results: 37 children were enrolled and 34 were included in the final efficacy analysis (1 withdrew prior to treatment and 2 did not return seizure diaries). Resolution of both hypsarhythmia and clinical spasms was achieved in in 9 of 12 participants (75%) treated with cosyntropin, 1/9 (11%) vigabatrin, and 5/13 (38%) cosyntropin and vigabatrin combined. The primary comparison of cosyntropin versus vigabatrin was significant (64% [95% confidence interval 21, 82], P < .01). Adverse events were reported in all 3 treatment arms: 31 (86%) had an adverse event, 7 (19%) had a serious adverse event, and 15 (42%) had an adverse event of special interest with no difference between treatment arms. Significance: This randomized trial was underpowered because of incomplete enrollment, yet it demonstrated that cosyntropin was more effective for short-term outcomes than vigabatrin as initial treatment for infantile spasms.

OBJECTIVES: To report the efficacy of intravenous (IV) synthetic ACTH (Tetracosactide) in the treatment of infantile spasms. METHODS: This is a retrospective chart review of patients with a diagnosis of infantile spasms conducted at the Pediatric Department of King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia, from 01-01-2005 to 31-12-2019. RESULTS: Of the 156 cases, 141 were treated initially with vigabatrin (VGB) with a complete response seen in 42(30%). Synthetic ACTH (Tetracosactide) IV injections were used in a total of 52 cases with response in 25(48%). Of the 35 cases which initially failed with VGB, 20(57%) responded to synthetic ACTH. The injections were used as a first line in 8 cases with response in 6(75%). The response to oral steroids was seen in 4/14(29%) cases. A relapse was seen in 2/42(5%) of patients treated with VGB and in 5/25(20%) of those who were treated with synthetic ACTH. The response was highest in the idiopathic group with 7/7(100%). Epilepsy at 2 years was seen in 26/50(52%) and 50/57(88%) of the responders and non-responders, respectively (p=0.000). Only 14/156(9%) of cases had a fair neurological outcome. All of them were from the responder group CONCLUSION: The response to VGB is suboptimal, while the response to synthetic ACTH is encouraging making it a good alternative for natural ACTH as a potential first line therapy in infantile spasms.

OBJECTIVES: The clinical presentation of patients with nonclassic 21-hydroxylase deficiency (N21OHD) is similar with that for other disorders of androgen excess. The diagnosis of N21OHD typically requires cosyntropin stimulation. Additionally, the management of such patients is limited by the lack of reliable biomarkers of androgen excess. Herein, we aimed to: (1.) compare the relative contribution of traditional and 11-oxyandrogens in N21OHD patients and (2.) identify steroids that accurately diagnose N21OHD with a single baseline blood draw. DESIGN: We prospectively enrolled patients who underwent a cosyntropin stimulation test for suspected N21OHD in two tertiary referral centers between January 2016 and August 2019. METHODS: Baseline sera were used to quantify 15 steroids by liquid chromatography-tandem mass spectrometry. Logistic regression modeling was implemented to select steroids that best discriminate N21OHD from controls. RESULTS: Of 86 participants (72 females), median age 26, 32 patients (25 females) had N21OHD. Age, sex distribution, and BMI were similar between patients with N21OHD and controls. Both testosterone and androstenedione were similar in patients with N21OHD and controls, while four 11-oxyandrogens were significantly higher in patients with N21OHD (ratios between medians: 1.7 to 2.2, P < 0.01 for all). 17α-Hydroxyprogesterone (6.5-fold), 16α-hydroxyprogesterone (4.1-fold), and 21-deoxycortisol (undetectable in 80% of the controls) were higher, while corticosterone was 3.6-fold lower in patients with N21OHD than in controls (P < 0.001). Together, baseline 17α-hydroxyprogesterone, 21-deoxycortisol, and corticosterone showed perfect discrimination between N21OHD and controls. CONCLUSIONS: Adrenal 11-oxyandrogens are disproportionately elevated compared to conventional androgens in N21OHD. Steroid panels can accurately diagnose N21OHD in unstimulated blood tests.

Rare or orphan diseases affect only small populations, thereby limiting the economic incentive for the drug development process, often resulting in a lack of progress towards treatment. Drug repositioning is a promising approach in these cases, due to its low cost. In this approach, one attempts to identify new purposes for existing drugs that have already been developed and approved for use. By applying the process of drug repositioning to identify novel treatments for rare diseases, we can overcome the lack of economic incentives and make concrete progress towards new therapies. Adrenocortical Carcinoma (ACC) is a rare disease with no practical and definitive therapeutic approach. We apply Heter-LP, a new method of drug repositioning, to suggest novel therapeutic avenues for ACC. Our analysis identifies innovative putative drug-disease, drug-target, and disease-target relationships for ACC, which include Cosyntropin (drug) and DHCR7, IGF1R, MC1R, MAP3K3, TOP2A (protein targets). When results are analyzed using all available information, a number of novel predicted associations related to ACC appear to be valid according to current knowledge. We expect the predicted relations will be useful for drug repositioning in ACC since the resulting ranked lists of drugs and protein targets can be used to expedite the necessary clinical processes.

OBJECTIVES: Postdural puncture headache is a challenging complication of diagnostic, therapeutic, and unintentional lumbar puncture. Literature evidence supports cosyntropin as a viable noninvasive therapy for adults who have failed conservative management, but pediatric data are limited. The purpose of this retrospective chart review was to describe the use of intravenous cosyntropin for refractory pediatric postdural puncture headache at a single free-standing tertiary care pediatric hospital. METHODS: Patients who had received cosyntropin were identified. Charts were retrospectively reviewed for indication, dosing information, efficacy, and side effects. The response was defined as a 50% reduction in pain score, with a secondary efficacy measure of time to discharge after the first dose. RESULTS: Over a 5-year period, 26 patients received 37 doses of cosyntropin. Dosing ranged from 5 to 15 mcg/kg (median, 10.4 mcg/kg). There was a significant reduction in pain scores after the first dose of cosyntropin (P=0.008). Eighty-one percent of patients (n=21) achieved either a 50% reduction in pain or were discharged within 24 hours after the first dose. The median time to 50% pain reduction in 13 patients who achieved it before or discharge was 5 hours (range, 1 to 30 h). The median time to discharge after the first dose was 20 hours (range, 2 to 72 h). Ten patients received >1 dose of cosyntropin. Three patients required an epidural blood patch. No adverse effects related to treatment were identified. DISCUSSION: This study suggests that while further research is warranted, cosyntropin is a potential alternative to epidural blood patch for pediatric patients with postdural puncture headache who fail conservative management.

CONTEXT: In autoimmune Addison's disease (AAD), exogenous glucocorticoid (GC) therapy is an imperfect substitute for physiological GC secretion. Patients on long-term steroid replacement have increased morbidity, reduced life expectancy, and poorer quality of life. OBJECTIVE: The objective of this article is to restore adrenocortical steroidogenic function in recent-onset AAD. DESIGN: An open-label, multicenter trial of immunotherapy and trophic stimulation in new-onset AAD was conducted. Serial measurement of serum and urine corticosteroids at baseline and throughout a 72-week follow-up period was performed. SETTING: This study was conducted at the.endocrine departments and clinical research facilities at 5 UK tertiary centers. PATIENTS: Thirteen participants (9 female, 4 male; age 19-64 years) were included with AAD confirmed by high adrenocorticotropin, low circulating cortisol (basal < 100 nmol/L or post-tetracosactide < 300 nmol/L), and positive serum 21-hydroxylase antibodies. INTERVENTION: All participants received dual therapy with B-lymphocyte-depleting immunotherapy (rituximab 1 g given twice) and repeated depot tetracosactide (1 mg on alternate days for 12 weeks). MAIN OUTCOME MEASURE: Restoration of normal GC secretion (stimulated cortisol > 550 nmol/L) at week 48 was the main outcome measure. RESULTS: Ten of 13 (77%) participants had detectable stimulated serum cortisol (26-265 nmol/L) at trial entry. Following intervention, 7 of 13 (54%) had an increase in stimulated cortisol measurement, with a peak response of 325 nmol/L at week 18 in 1 participant. Increased steroid metabolites, assayed by urine gas chromatography-mass spectrometry at week 12 and week 48, was detected in 8 of 13 (62%) individuals, reflecting an increase in endogenous steroidogenesis. Four of 13 had residual adrenal function at 72 weeks. CONCLUSION: Combined treatment with rituximab and depot tetracosactide did not restore normal adrenal function. Nevertheless, adrenocortical plasticity is demonstrated in some patients, and this has the potential to be exploited to improve adrenal function.

OBJECTIVE: To assess and compare diagnostic value of 30-minute cortisol level over 60-minute level in the diagnosis of adrenal insufficiency. METHODS: The comparative cross-sectional study was conducted at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from August 2017 to May 2018, and comprised patients referred to the facility for short synacthen test with suspicion of adrenal insufficiency. Blood samples for serum cortisol were taken at time-0 and then 30 and 60 minutes after the adreno-cortico-tropic hormone injection. Total serum cortisol was measured. Adrenal insufficiency was defined as stimulated cortisol level <500 nmol/l at 30 and 60 minutes post-stimulation. SPSS 24 was used for data analysis. RESULTS: Of the 111 subjects, 56(50.4%) were males and 55(49.5%) were females. Overall mean age was 34±20 years. Mean basal serum cortisol level was 110±98 nmol/l in patients with adrenal insufficiency and it was 294±164 nmol/l in patients with intact adrenal functions. Cortisol level at both 30 and 60 minutes was significant (p<0.001). Receiver Operating Characteristics curve was plotted which showed area under curve of 0.83 and 0.82 for 60 and 30 minutes respectively. CONCLUSIONS: The 30-minute cortisol level post-stimulation carried no diagnostic value . Measuring cortisol level once at 60-minute post-stimulation would be of more value apart from being cost-effective in the diagnosis of adrenal insufficiency.

BACKGROUND: Infantile spasms constitute a severe form of epileptic encephalopathy. In the International Collaborative Infantile Spasms Study (ICISS), we showed that combining vigabatrin with hormonal therapy was more effective than hormonal therapy alone at stopping spasms between days 14 and 42 of treatment. In this planned follow-up, we aimed to assess whether combination therapy was associated with improved developmental and epilepsy outcomes at 18 months of age. METHODS: In ICISS, a multicentre, open-label, randomised controlled trial, infants were enrolled from 102 hospitals (three in Australia, 11 in Germany, two in New Zealand, three in Switzerland, and 83 in the UK). Eligible infants had a clinical diagnosis of infantile spasms and a hypsarrhythmic (or similar) electroencephalogram (EEG) no more than 7 days before enrolment. Participants were randomly assigned (1:1) by a secure website to receive hormonal therapy with vigabatrin or hormonal therapy alone. If parents consented, there was an additional randomisation (1:1) of type of hormonal therapy used (prednisolone or tetracosactide depot). Block randomisation was stratified for hormonal treatment and risk of developmental impairment. Parents and clinicians were not masked to therapy, but investigators assessing epilepsy and developmental outcomes at 18 months were masked to treatment allocation. Minimum doses were oral prednisolone 10 mg four times a day or intramuscular tetracosactide depot 0·5 mg (40 IU) on alternate days with or without oral vigabatrin 100 mg/kg per day. The primary outcome at 18 months was development as assessed by the Vineland Adaptive Behaviour Scales (VABS) composite score. Secondary outcomes were the presence or absence of epileptic seizures or infantile spasms in the previous 28 days, as recorded by parents and carers, and the use of any anti-epileptic treatment (including ketogenic diet) in the previous 28 days. Analysis was by intention to treat. The trial is registered with the ISRCTN registry, number 54363174, and EudraCT, number 2006-000788-27. FINDINGS: Between March 7, 2007, and May 22, 2014, 766 infants were screened and, of those, 377 were randomly assigned to hormonal therapy with vigabatrin (n=186) or hormonal therapy alone (n=191). 362 infants were assessed for developmental and epilepsy outcomes at 18 months, 181 in each treatment group. Mean VABS scores did not differ significantly between the combination therapy group and the hormonal therapy alone group (73·9 [SE 1·3] vs 72·7 [1·4], difference -1·2 [95% CI -4·9 to 2·6], p=0·55). Presence of epilepsy at the assessment at age 18 months was similar in both treatment groups (54 [30·0%] of 180 infants who received combination therapy vs 52 [29·2%] of 178 who received hormonal therapy alone; difference 0·8% [95% CI -8·8 to 10·4], p=0·90). Presence of spasms was also similar in both treatment groups (27 [15·0%] of 180 infants on combination therapy vs 28 [15·7%] of 178 on hormonal therapy alone; difference 0·7% [95% CI -6·9 to 8·3], p=0·85). At the 18-month assessment, 158 (44·1%) of 358 infants were on some form of anti-epileptic treatment. Initial control of spasms between days 14 and 42 of treatment was associated with higher mean VABS scores at 18 months (79·1 [SE 1·2] vs 63·2 [1·1], difference 15·9 [95% CI 12·4 to 19·5], p<0·001) and with higher likelihood of absence of seizures at 18 months (in 39 [17·0%] of 229 infants who achieved spasm cessation vs 67 [51·9%] of 129 who did not; difference 34·9% [24·8 to 45·0], p<0·001). Increasing lead-time to treatment was associated with lower VABS scores (analysis of variance: F[4,354]=6·38, p<0·001) and worse epilepsy outcomes (p=0·023). INTERPRETATION: Combination therapy did not result in improved developmental or epilepsy outcomes at 18 months. However, early clinical response to treatment was associated with improved developmental and epilepsy outcomes at 18 months. Longer lead-time to treatment was associated with poorer outcomes. Rapid diagnosis and effective treatment of infantile spasms could therefore improve outcomes.

BACKGROUND: Synthetic adrenocorticotropic hormone (ACTH) has been demonstrated to be effective in patients with membranous nephropathy, minimal change disease and some histological subtypes of focal segmental glomerulosclerosis. Its clinical impact in patients with IgA nephropathy is currently unclear. CASE PRESENTATION: In this report, we describe the clinical use of ACTH in patients with IgA nephropathy. Three female patients (24-44 years) with overt proteinuria received intramuscular (IM) ACTH for varying time periods (8-14 months). Pre-treatment urine protein varied from 2.9 g/d to 4.3 g/d. CONCLUSIONS: There was complete remission in one patient on ACTH monotherapy and in the other two when prescribed as a steroid-sparing agent in combination with cyclophosphamide. All three had resolution in proteinuria to less than 1 g/d and maintained their GFR to baseline values. There were no reported side effects at a once a week dose. This study illustrates that ACTH is an effective agent that is well tolerated with minimal side effects and can be used as an alternative to prednisone in patients with IgA nephropathy.

Opsoclonus-myoclonus syndrome (OMS) is a neuroinflammatory disorder with pervasive morbidity that warrants better treatments. Twelve children with moderate/severe OMS (total score 23 ± 6) who did not remit to multiple immunotherapies were evaluated for neuroinflammation in a case-control study using cerebrospinal fluid (CSF) lymphocyte subset analysis by flow cytometry, chemokine/cytokine analysis by enzyme-linked immunoadsorption assay (ELISA), and oligoclonal bands by immunofixation with isoelectric focusing. Observations made on empirical treatment with rituximab, IVIg, and tetracosactide combination immunotherapy (coined "RITE-CI") were analyzed. All of the patients tested for multiple inflammatory markers were positive; 75% had ≥3 CSF markers. Fifty percent had CSF oligoclonal bands; 58%, B cell expansion; and 50 to 100%, elevated concentrations of multiple chemokines and neuronal/axonal marker neurofilament light chain. After RITE-CI, total score dropped significantly in the group (-85%, p < 0.0001) from moderate to trace, and by 2 to 4 severity categories in each patient. The 24-week schedule was well tolerated and clinically effective for moderate or severe OMS, as were other schedules. RITE-CI is feasible and effective as rescue therapy and presents an initial option for children with moderate/severe OMS. Though preliminary, the schedule can be adjusted to patient severity, propensity for relapse, and other factors.

We recently published a comparison of two hydrocortisone dosage regimens in patients with septic shock. We compare the results conferred by the two regimens as a function of the response to cosyntropin stimulation test (CST). Patients with septic shock were treated by one of two hydrocortisone regimens: either a 50-mg intravenous bolus every 6 h during 7 days (200âmg group; nâ=â49), or a 100-mg initial bolus followed by a continuous infusion of 300âmg daily for 5 days (300âmg group; nâ=â50). Nonresponders was defined as a CST response of 9âµg/dL or less. Nonresponders had more severe septic shock, greater fluid resuscitation needs, and greater vasopressor dependence than responders. When analyzed only as a function of CST results, there was no difference in survival between responders and nonresponders. However, analyses crossing CST results and the treatment regimens showed that patients who were responders and in the 300âmg group had significantly less intensive care unit mortality compared with responders in the 200âmg group (respective mortality of 24% vs. 55% [relative risk 0.43, 95% confidence interval, 0.20 to 0.94, Pâ=â0.018]). Multivariate analysis identified baseline blood cortisol as an independent prognostic factor for 28-day mortality in all groups (hazard ratio 1.002, 95% confidence interval, 1.001 to 1.002, Pâ≤â0.0001). The results suggest that in patients who respond to CST, hydrocortisone can provide a dose-dependent benefit. In contrast, nonresponse may indicate corticosteroid resistance. This heterogeneity of response to hydrocortisone may explain the difficulties encountered when trying to demonstrate its benefit in septic shock.

BACKGROUND: Cardiogenic shock shares with septic shock common hemodynamic features, inflammatory patterns, and most likely similar complications such as critical illness-related corticosteroid insufficiency. The aim of this study was to evaluate the prevalence of critical illness-related corticosteroid insufficiency in cardiogenic shock patients and to secondarily assess its prognostic value on 90-day mortality. METHODS: A single-center prospective observational study conducted over a 3-year period and including all patients with cardiogenic shock. Main exclusion criteria were patients with prior cardiac arrest, sepsis, ongoing corticosteroid therapy, and etomidate administration. A short corticotropin test was performed in the first 24âh following admission. Serum cortisol levels were measured before (T0) and 60âmin (T60) after administration of 250âµg of cosyntropin. Critical illness-related corticosteroid insufficiency was defined according to the 2017 consensus definition (basal total cortisol<10âµg·dL or a delta cortisol T60-T0<9âµg·dL) as well as the thresholds published in 2016 in cardiogenic shock patients associated with worst prognosis (basal total cortisol>29âµg·dL and delta cortisol T60-T0<17âµg·dL). RESULTS: Seventy-nine consecutive patients hospitalized in intensive care for cardiogenic shock met the inclusion criteria. Overall mortality was 43% at day 90. Forty-two percent had critical illness-related corticosteroid insufficiency using the 2017 consensus definition and 32% using the 2016 cardiogenic shock thresholds. Presence of critical illness-related corticosteroid insufficiency was not an independent factor associated with 90-day mortality irrespective of the thresholds used. CONCLUSION: Critical illness-related corticosteroid insufficiency is a frequent occurrence in medical cardiogenic shock. However, in this study, such insufficiency was not associated with prognosis.

Introducción. La vigabatrina (VGB) es un fármaco de primera línea para el tratamiento de espasmos infantiles. Diversos estudios han hallado anomalías en la resonancia magnética (RM) cerebral, que afectaban particularmente a los ganglios de la base, y especialmente en secuencias de difusión, en lactantes con espasmos que recibían VGB en altas dosis (> 100 mg/kg/día), y se ha observado la desaparición de las lesiones tras la retirada de dicho tratamiento. Casos clínicos. Se presentan dos casos clínicos con inicio de una encefalopatía epiléptica en el primer año de vida y crisis en forma de espasmos infantiles. Ambos recibieron tratamiento con distintos fármacos, entre ellos VGB hasta dosis de 200 mg/kg/día. Con 11 y 28 meses de vida, respectivamente, aparecían imágenes en la RM cerebral con una marcada hiperintensidad de señal en secuencias ponderadas en T2 en ambos pálidos, tálamos, porción posterior del tronco encefálico y núcleos dentados, que asociaban restricción en secuencias de difusión. Ambos disponían de estudios previos de RM, sin alteraciones. Tras excluir una metabolopatía subyacente, se decidió la retirada de la VGB y tres meses después, en una RM de control, se apreció la total reversibilidad de dichas lesiones. Conclusiones. Deben evaluarse con cautela los hallazgos de la RM cerebral en lactantes que reciban VGB en altas dosis para el tratamiento de espasmos. Su aparente efecto citotóxico sobre los ganglios de la base podría simular metabolopatías/ enfermedades mitocondriales. Conocer este efecto de la VGB y sus características típicas en la RM puede evitar pruebas innecesarias, como una biopsia muscular o un nuevo cribado metabólico (AU)
Introduction. Vigabatrin (VGB) is a first-line drug for the treatment of infantile spasms. Recently, several reports claim the existence of abnormalities in magnetic resonance imaging (MRI) (particularly affecting basal ganglia, and visible in T2 and diffusion sequences) in infants with spasms that were receiving high doses of VGB (> 100 mg/kg/day), which appear to be reversible after withdrawal of treatment. Case reports. We present two cases with an epileptic encephalopathy in the first year of life and seizures consisting of infantile spasms. Both were treated with several antiepileptic drugs, including VGB up to a maximum dosage of 200 mg/ kg/day. At the age of 11 and 28 months, respectively, MRI images showed marked signal hyperintensities on T2-sequences on bilateral globus pallidus, thalamus, posterior portion of the brainstem and dentate nuclei, also visible on diffusion sequences. Both had previous unaltered MRI studies. After excluding an underlying metabolic disease, VGB withdrawal is decided, appreciating the reversibility of those lesions in a prospective MRI study, three months later. Conclusions. We must consider and carefully evaluate findings on brain MRI in infants receiving VGB at high doses for treatment of spasms. The apparent cytotoxic effect on basal ganglia could simulate metabolic/mitochondrial diseases. By knowing this effect of VGB and its typical MRI features, unnecessary testing can be avoided in young infants with epileptic encephalopathies, including complex procedures like muscle biopsy or a new metabolic screening (AU)

BACKGROUND: Relative adrenal insufficiency (RAI) is common in intensive care unit patients, particularly during septic shock (SS). Cardiogenic shock (CS) may share some pathophysiological features with SS. The aim of this study was to evaluate the prevalence and long-term prognosis of RAI during CS. PATIENTS AND METHODS: Prospective observational study conducted in the intensive care and cardiology units in one university hospital in France. Patients meeting the criteria for CS without prior corticosteroid therapy were included. Total blood cortisol levels were assessed immediately before (T0) a short corticotropin stimulation test (0.25âmg i.v. of tetracosactrin) and 30 and 60 min afterward. Δmax was defined as the difference between the maximal value after the test and T0. RESULTS: Of the 92 patients enrolled, 42 (46%) (95% confidence interval [CI] [36%-56%]) died in hospital and 7 more died during a median follow-up of 616 [57-2,498] days, for an overall mortality rate of 53% (95% CI [43%-63%]). Three groups were identified based on the corticotropin test: group 1 (T0 ≤798ânmol/L and Δmax >473ânmol/L), group 2 ([T0 >798ânmol/L and Δmax >473ânmol/L] or [T0 ≤798ânmol/L and Δmax ≤473ânmol/L]), and group 3 (T0 >798ânmol/L and Δmax ≤473ânmol/L) with an overall survival of 76%, 43%, and 15%, respectively (log rank Pâ=â0.003). In the multivariable analysis, adrenal nonresponse (group 3) was an independent predictor of mortality (Pâ=â0.04), along with left ventricular ejection fraction, Simplified Acute Physiology Score II, and cardiac arrest. CONCLUSIONS: These data suggest that a short corticotropin test has a good prognostic value in CS and allows identifying patients at higher risk of death.

BACKGROUND: Infantile spasms constitutes a severe infantile epilepsy syndrome that is difficult to treat and has a high morbidity. Hormonal therapies or vigabatrin are the most commonly used treatments. We aimed to assess whether combining the treatments would be more effective than hormonal therapy alone. METHODS: In this multicentre, open-label randomised trial, 102 hospitals (Australia [three], Germany [11], New Zealand [two], Switzerland [three], and the UK [83]) enrolled infants who had a clinical diagnosis of infantile spasms and a hypsarrhythmic (or similar) EEG no more than 7 days before enrolment. Participants were randomly assigned (1:1) by a secure website to receive hormonal therapy with vigabatrin or hormonal therapy alone. If parents consented, there was an additional randomisation (1:1) of type of hormonal therapy used (prednisolone or tetracosactide depot). Block randomisation was stratified for hormonal treatment and risk of developmental impairment. Parents and clinicians were not masked to therapy, but investigators assessing electro-clinical outcome were masked to treatment allocation. Minimum doses were prednisolone 10 mg four times a day or intramuscular tetracosactide depot 0·5 mg (40 IU) on alternate days with or without vigabatrin 100 mg/kg per day. The primary outcome was cessation of spasms, which was defined as no witnessed spasms on and between day 14 and day 42 from trial entry, as recorded by parents and carers in a seizure diary. Analysis was by intention to treat. The trial is registered with The International Standard Randomised Controlled Trial Number (ISRCTN), number 54363174, and the European Union Drug Regulating Authorities Clinical Trials (EUDRACT), number 2006-000788-27. FINDINGS: Between March 7, 2007, and May 22, 2014, 766 infants were screened and, of those, 377 were randomly assigned to hormonal therapy with vigabatrin (186) or hormonal therapy alone (191). All 377 infants were assessed for the primary outcome. Between days 14 and 42 inclusive no spasms were witnessed in 133 (72%) of 186 patients on hormonal therapy with vigabatrin compared with 108 (57%) of 191 patients on hormonal therapy alone (difference 15·0%, 95% CI 5·1-24·9, p=0·002). Serious adverse reactions necessitating hospitalisation occurred in 33 infants (16 on hormonal therapy alone and 17 on hormonal therapy with vigabatrin). The most common serious adverse reaction was infection occurring in five infants on hormonal therapy alone and four on hormonal therapy with vigabatrin. There were no deaths attributable to treatment. INTERPRETATION: Hormonal therapy with vigabatrin is significantly more effective at stopping infantile spasms than hormonal therapy alone. The 4 week period of spasm cessation required to achieve a primary clinical response to treatment suggests that the effect seen might be sustained, but this needs to be confirmed at the 18 month follow-up.

BACKGROUND: Cardiopulmonary bypass (CPB) may lead to adrenal insufficiency (AI). Emerging evidence supports association of AI with morbidity after cardiac surgery. AIMS: The aim of this study was to define AI incidence in neonates undergoing complex cardiac surgery with CPB and its association with intraoperative post-CPB outcomes. METHODS: Forty subjects enrolled in a prior randomized control trial who received preoperative methylprednisolone as part of our institutional neonatal bypass protocol were included. No intraoperative steroids were given. ACTH stimulation tests were performed: preoperatively and 1 h after separation from CPB. AI was defined as <9 µg·ml-1 increase in cortisol at 30 min post cosyntropin 1 mcg. Clinical outcomes were collected up to 90 min after CPB. RESULTS: 2/40 (5%) subjects had preoperative AI vs 13/40 (32.5%) post-CPB AI, P ≤ 0.001. No significant difference was observed in age, gestational age, weight, CPB time, circulatory arrest, or STAT category between subjects with or without post-CPB AI. ACTH decreased from preoperative values 127.3 vs 35 pcg·ml-1 [median difference = 81.8, 95% CI = 22.7-127.3], while cortisol increased from 18.9 vs 75 µg·dl-1 [median difference = 52.2, 95% CI = 36.3-70.9]. Post-CPB AI was associated with increased median colloid resuscitation, 275 vs 119 ml·kg-1 [median difference = 97.8, 95% CI = 7.1-202.2]; higher median peak lactate, 9.4 vs 6.9 mg·dl-1 [median difference = 3.2, 95% CI = 0.04-6.7]; median post-CPB lactate, 7.9 vs 4.3 mg·dl-1 , [median difference 3.6, 95% CI = 2.1-4.7], and median lactate on admission to CICU, 9.4 vs 6.0 mg·dl-1 [median difference = 3, 95% CI = 1.1-4.9]. No difference was observed in blood pressure or vasoactive inotrope score at any time point measured in operating room (OR). Higher initial post-CPB cortisol correlated with decreased cosyntropin response. CONCLUSIONS: Neonatal cardiac surgery with CPB and preoperative methylprednisolone leads to AI as determined by low-dose ACTH stimulation test in one-third of patients. AI is associated with increased serum lactate and colloid resuscitation in OR. Impact of preoperative methylprednisolone on results is not defined. Benefit of postoperative steroid administration in neonates with post-CPB AI warrants further investigation.
