RESUMEN

BACKGROUND: Adrenal insufficiency is usually diagnosed in children who will need lifelong hydrocortisone therapy. However, medicines for pediatrics, in terms of dosage and acceptability, are currently unavailable. RESEARCH DESIGN AND METHODS: Semi-solid extrusion (SSE) 3D printing (3DP) was utilized for manufacturing of personalized and chewable hydrocortisone formulations (printlets) for an upcoming clinical study in children at Vall d'Hebron University Hospital in Barcelona, Spain. The 3DP process was validated using a specific software for dynamic dose modulation. RESULTS: The printlets contained doses ranging from 1 to 6 mg hydrocortisone in three different flavor and color combinations to aid adherence among the pediatric patients. The pharma-ink (mixture of drugs and excipients) was assessed for its rheological behavior to ensure reproducibility of printlets through repeated printing cycles. The printlets showed immediate hydrocortisone release and were stable for 1 month of storage, adequate for prescribing instructions during the clinical trial. CONCLUSIONS: The results confirm the suitability and safety of the developed printlets for use in the clinical trial. The required technical information from The Spanish Medicines Agency for this clinical trial application was compiled to serve as guidelines for healthcare professionals seeking to apply for and conduct clinical trials on 3DP oral dosage forms.

RESUMEN

BACKGROUND: Mitotane is the cornerstone of adjuvant adrenocortical cancer (ACC) treatment. However, its use is burdened with frequent adverse events. METHODS: A retrospective analysis of adverse events was performed in 26 ACC patients adjuvantly treated with mitotane. RESULTS: Mitotane toxicity was present in all patients (100%). Two (7.7%) patients developed 1-3 adverse events, 15 (57.7%) experienced 4-6 adverse events and 9 (34.6%) patients had more than 6 adverse events. Two (7.7%) patients discontinued mitotane due to adverse events. CONCLUSION: Careful monitoring and timely management are essential for ensuring mitotane treatment adherence and maximizing its benefits.

RESUMEN

Intensive care unit (ICU) admissions in the United States exceed 5.7 million annually, often leading to complications such as post-intensive care syndrome and high mortality rates. Among these challenges, critical illness-related corticosteroid insufficiency (CIRCI) requires emphasis due to its complex, multiple-cause pathophysiology and varied presentations. CIRCI, characterized by adrenal insufficiency during critical illness, presents in up to 30% of ICU patients and may manifest as an exaggerated inflammatory response. Factors such as dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, altered cortisol metabolism, tissue corticosteroid resistance, and drug-induced suppression contribute to CIRCI. Diagnosis is a complex process, relying on a comprehensive assessment including clinical presentation, laboratory findings, and dynamic stimulatory testing. Treatment involves intensive medical care and exacting glucocorticoid therapy. Recent guidelines advocate for individualized approaches tailored to patient presentation and etiology. Understanding the pathophysiology and treatment of CIRCI is vital for clinicians managing critically ill patients and striving to improve outcomes. This research paper aims to explore the latest developments in the pathophysiology and management of CIRCI.

RESUMEN

BACKGROUND: The combination of intravenous hydrocortisone and enteral fludrocortisone may reduce mortality in patients with septic shock. The optimal dose and reliability of absorption of fludrocortisone in critically ill patients are unclear. METHODS: In a multi-centre, open label, phase II randomized clinical trial, intravenous hydrocortisone alone or in combination with one of three doses of enteral fludrocortisone (50 µg, 100 µg or 200 µg daily) for 7 days was compared in patients with septic shock. The primary outcome was time to shock resolution. We conducted pharmacokinetic studies to assess absorption. RESULTS: Out of 153 enrolled patients, 38 (25%) received hydrocortisone alone, 42 (27%) received additional 50 µg, 36 (24%) received 100 µg and 37 (24%) received 200 µg fludrocortisone. Plasma concentrations of fludrocortisone were detected in 97% of patients at 3 h-median (interquartile range [IQR]) 261 (156-334) ng/L. There was no significant difference in the time to shock resolution between groups with median (IQR) of 3 (2.5-4.5), 3 (2-4), 3 (2-6) and 3 (2-5.5) days in the hydrocortisone alone, 50 µg, 100 µg and 200 µg fludrocortisone groups, respectively. The corresponding 28-day mortality rates were 9/38 (24%), 7/42 (17%), 4/36 (11%) and 4/37 (11%), respectively. There were no significant differences between groups with respect to, recurrence of shock, indices of organ failure or other secondary outcomes. CONCLUSIONS: Enteral fludrocortisone resulted in detectable plasma fludrocortisone concentrations in the majority of critically ill patients with septic shock, although they varied widely indicating differing absorption and bioavailability. Its addition to hydrocortisone was not associated with shorter time to shock resolution.

RESUMEN

BACKGROUND: Primary human hepatocytes (PHHs) are highly valuable for drug-metabolism evaluation, liver disease modeling and hepatocyte transplantation. However, their availability is significantly restricted due to limited donor sources, alongside their constrained proliferation capabilities and reduced functionality when cultured in vitro. To address this challenge, we aimed to develop a novel method to efficiently expand PHHs in vitro without a loss of function. METHODS: By mimicking the in vivo liver regeneration route, we developed a two-step strategy involving the de-differentiation/expansion and subsequent maturation of PHHs to generate abundant functional hepatocytes in vitro. Initially, we applied SiPer, a prediction algorithm, to identify candidate small molecules capable of activating liver regenerative transcription factors, thereby formulating a novel hepatic expansion medium to de-differentiate PHHs into proliferative human hepatic progenitor-like cells (ProHPLCs). These ProHPLCs were then re-differentiated into functionally mature hepatocytes using a new hepatocyte maturation condition. Additionally, we investigated the underlying mechanism of PHHs expansion under our new conditions. RESULTS: The novel hepatic expansion medium containing hydrocortisone facilitated the de-differentiation of PHHs into ProHPLCs, which exhibited key hepatic progenitor characteristics and demonstrated a marked increase in proliferation capacity compared to cells cultivated in previously established expansion conditions. Remarkably, these subsequent matured hepatocytes rivaled PHHs in terms of transcriptome profiles, drug metabolizing activities and in vivo engraftment capabilities. Importantly, our findings suggest that the enhanced expansion of PHHs by hydrocortisone may be mediated through the PPARα signaling pathway and regenerative transcription factors. CONCLUSIONS: This study presents a two-step strategy that initially induces PHHs into a proliferative state (ProHPLCs) to ensure sufficient cell quantity, followed by the maturation of ProHPLCs into fully functional hepatocytes to guarantee optimal cell quality. This approach offers a promising means of producing large numbers of seeding cells for hepatocyte-based applications.

RESUMEN

Oral hormone replacement therapy has been and continues to be the cornerstone of adrenocortical insufficiency management. However, the introduction of continuous subcutaneous hydrocortisone infusion (CSHI) shows great potential for advancing the management of adrenocortical insufficiency. It resembles the circadian rhythm of physiological cortisol secretion and was shown to have a promising outcome in terms of quality of life (QOL) and clinical outcomes in the literature. We conducted a systematic search strategy including MEDLINE, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and the online trials registers at ClinicalTrials.gov without geographic restrictions. Research investigations where self-reported quality of life (QOL) was assessed as a variable in adult individuals with confirmed adrenal disease, treated by CSHI, and results were presented in English. All articles included were published between 2014 and 2023, even though we had no timeframe limitations in our inclusion criteria. A total of six studies were included, with 63 subjects enrolled, and the average age was 40 years, a study showed a significant reduction in the average total daily dose of HC from 47.5 mg to 31.4 mg on CSHI, while other two studies estimated a reduction in the hospitalization rate due to adrenal crisis from 2.6 to 1.3 admissions per year on CSHI. Most of the studies on subjective well-being and quality of life have shown significant improvement. Overall, CSHI shows great potential as a treatment method for Adrenal insufficiency. It improves the quality of life and lowers hospitalization rates, resulting in increased patient satisfaction and acceptance. Additional comprehensive research is necessary to strengthen these discoveries, gain a deeper understanding of the effectiveness and safety of this treatment approach, and provide guidance for medical practitioners.

RESUMEN

Introduction: Atopic dermatitis (AD) is a type of chronic inflammatory disorder that affects children. Aim: To investigate whether hydrocortisone or tacrolimus could be more effective for treating AD in children. Patients and methods: This clinical randomized investigation included 100 children with AD who met the eligibility criteria. AD patients were recruited from Tanta University's Dermatology Department and divided into two groups (n = 50)., For four months, group 1 (the hydrocortisone group) received topical hydrocortisone cream. Group 2 received topical tacrolimus for four months. A dermatologist evaluated the patients at the start and four months after the treatment had been initiated to measure serum concentrations of neutrophil chemoattractant growth-related oncogene-α (GRO-α), interferon gamma induced protein 10 (IP-10), tumor necrosis factor alpha (TNF-α), vascular adhesion molecule 1 (VCAM-1), intercellular adhesion molecule 1 (ICAM-1). All patients were examined using the modified Eczema Area and Severity Index (mEASI) score. Results: Tacrolimus group showed a significant reduction in serum levels of all measured biomarkers (p < 0.05) when compared to its baseline and when compared to the hydrocortisone group. Both groups displayed a significant decline in mEASI score in comparison with their baseline values (p < 0.05). Conclusion: In children with AD, tacrolimus reduces inflammatory biomarkers better than hydrocortisone, suggesting its potential as a more effective treatment option.

RESUMEN

Background: The combined effects of metformin and epigallocatechin-3-gallate (EGCG) on cortisol, 11ß-hydroxysteroid dehydrogenase type 1 (11ß-HSD1), and blood glucose levels have not been investigated. This study evaluated the effectiveness of combining EGCG with metformin in regulating those levels in a rat model of diet-induced diabetes and obesity. Methods: Thirty diabetic and obese rats on a high-fat diet were treated daily for 28 days with EGCG (100 mg/kg of body weight/day), metformin (200 mg/kg of body weight/day), or both. Control groups comprised lean rats, untreated obese diabetic rats, and metformin-only-treated rats. Blood samples were collected to measure cortisol and fasting blood glucose (FBG) levels and liver tissue samples were examined for 11ß-HSD1 levels. Results: Rats receiving combination therapy had significantly reduced cortisol levels (from 36.70±15.13 to 31.25±7.10 ng/mL) compared with the untreated obese diabetic rats but not the rats receiving monotherapy. Rats receiving combination therapy and EGCG monotherapy had significantly lower 11ß-HSD1 levels compared with the untreated obese diabetic rats (92.68±10.82 and 93.74±18.11 ng/L vs. 120.66±14.00 ng/L). Combination therapy and metformin monotherapy significantly reduced FBG levels (440.83±133.3 to 140.50±7.36 mg/dL and 480.67±86.32 to 214.17±102.78 mg/dL, respectively) by approximately 68.1% and 55.4% compared with rats receiving EGCG monotherapy and untreated obese diabetic rats. Conclusion: Combining EGCG with metformin exhibited synergistic effects compared with monotherapy for managing diabetes, leading to improved outcomes in reduction of baseline cortisol levels along with reduction in 11ß-HSD1 and blood glucose levels.

RESUMEN

BACKGROUND: This study assessed the effect of hydrocortisone-fludrocortisone combination therapy on the mortality of patients with septic shock. METHODS: A literature search was conducted using Medline, Embase, the Cochrane Library, ClinicalTrials.gov, and other databases for articles published until October 1, 2023. Only clinical studies that assessed the clinical efficacy and safety of hydrocortisone-fludrocortisone therapy for the treatment of septic shock were included. The primary outcome was the in-hospital mortality rate. RESULTS: Seven studies with a total of 90, 756 patients were included. The study group exhibited lower in-hospital mortality rates (40.8% vs. 42.8%; OR, 0.86; 95% CI, 0.80-0.92). Compared to the control group, the study group also had lower intensive care unit (ICU) mortality (OR, 0.77; 95% CI, 0.63-0.95), 28-day mortality (OR, 0.85; 95% CI, 0.72-1.00), 90-day mortality (OR, 0.85; 95% CI, 0.71-1.01), 180-day mortality (OR, 0.82; 95% CI, 0.68-0.90), and one-year mortality (OR, 0.70; 95% CI, 0.42-1.16). Subgroup analyses showed a similar trend, particularly prominent in the pooled analysis of randomized clinical trials, multicenter studies, and ICU patients, the study drug regimen involved hydrocortisone at a dose of 50 mg every 6 h in combination with fludrocortisone at 50 µg daily, with the control group receiving either placebo or standard care. Hydrocortisone-fludrocortisone also increased vasopressor-free days and reduced vasopressor duration, without elevating the risk of adverse events. CONCLUSIONS: This study emphasizes the potential survival benefits of hydrocortisone-fludrocortisone combination therapy for patients with septic shock and its additional advantages, including reduced vasopressor use.

RESUMEN

BACKGROUND: Sepsis presents a challenge due to its complex immune responses, where balance between inflammation and anti-inflammation is critical for survival. Glucocorticoid-induced leucine zipper (GILZ) is key protein in achieving this balance, suppressing inflammation and mediating glucocorticoid response. This study aims to investigate GILZ transcript variants in sepsis patients and explore their potential for patient stratification and optimizing glucocorticoid therapy. METHODS: Sepsis patients meeting the criteria outlined in Sepsis-3 were enrolled, and RNA was isolated from whole blood samples. Quantitative mRNA expression of GILZ transcript variants in both sepsis patient samples (n = 121) and the monocytic U937 cell line (n = 3), treated with hydrocortisone and lipopolysaccharides, was assessed using quantitative PCR (qPCR). RESULTS: Elevated expression of GILZ transcript variant 1 (GILZ TV 1) serves as a marker for heightened 30-day mortality in septic patients. Increased levels of GILZ TV 1 within the initial day of sepsis onset are associated with a 2.2-[95% CI 1.2-4.3] fold rise in mortality, escalating to an 8.5-[95% CI 2.0-36.4] fold increase by day eight. GILZ TV1 expression is enhanced by glucocorticoids in cell culture but remains unaffected by inflammatory stimuli such as LPS. In septic patients, GILZ TV 1 expression increases over the course of sepsis and in response to hydrocortisone treatment. Furthermore, a high expression ratio of transcript variant 1 relative to all GILZ mRNA TVs correlates with a 2.3-fold higher mortality rate in patients receiving hydrocortisone treatment. CONCLUSION: High expression of GILZ TV 1 is associated with a higher 30-day sepsis mortality rate. Moreover, a high expression ratio of GILZ TV 1 relative to all GILZ transcript variants is a parameter for identifying patient subgroups in which hydrocortisone may be contraindicated.

RESUMEN

The management of adrenal insufficiency is challenging, and the overall goals of treatment are to prevent life-threatening adrenal crises, to optimize linear growth, to control androgen levels without overdosing in subjects with congenital adrenal hyperplasia (CAH) and to improve quality of life in affected individuals. Standard glucocorticoid formulations fail to replicate the circadian rhythm of cortisol and control the adrenal androgen production driven by adrenocorticotropic hormone. In order to personalize and tailor glucocorticoid therapy and to improve patient outcomes, new pharmacological strategies have been developed that best mimic physiological cortisol secretion. Novel therapeutic approaches in the management of adrenal insufficiency include new ways to deliver circadian cortisol replacement as well as various adjunctive therapies to reduce androgen production and/or androgen action/effects. Preclinical studies are exploring the role of restorative cell-based therapies, and a first recombinant adeno-associated virus-based gene therapy is also being developed in humans with CAH. In this article, we present three illustrative cases of adrenal insufficiency with different underlying etiologies and times of presentation. Diagnostic and management processes are discussed with emphasis on treatment and outcomes. We have also provided the most up-to-date evidence for the tailored management of children and adolescents with adrenal insufficiency.

RESUMEN

Objective. The hormonal balance is dependent on the internal and external stimuli. The baseline cortisol (BC) and thyroid stimulating hormone (TSH) levels have been observed to vary and have a predictive value in critical illness settings. Few reports have studied their variation in non-severe acute illness. The present study aims to describe the variation of BC and TSH levels and to determine the factors influencing BC and TSH levels in patients admitted with non-severe acute illness. Patients and Methods. This is a cross-sectional study of patients admitted to Infectious Diseases and Endocrinology units at the Department of Endocrinology-Diabetology and Internal Medicine at Tahar Sfar University Hospital between March 15th and September 15th, 2020. BC and TSH levels were obtained during the hospitalization. Results. A total of 143 patients were included in this study with 75 presenting with infection. All infections were community-acquired and predominantly non-severe. The BC levels were higher in patients with infection (p=0.004), especially those admitted via the emergency department (p=0.009) with a fever (p=0.015). The BC positively correlated with the temperature (p=0.002, r'=0.350), CRP levels (p=0.002, r'=0.355), neutrophil to lymphocyte ratio (p=0.045, r'=0.235), and SOFA score (p=0.023, r'=0.262). On the other hand, TSH levels were comparable in the presence of infection (p=0.400). TSH levels did not correlate with the fever, the severity of infection, or inflammation biomarkers. Both BC and TSH did not predict unfavorable outcomes in non-severe infected patients. Conclusion. In patients admitted with critical acute infections, the BC levels seem to indicate a relatively more severe infectious state. On the other hand, TSH levels did not show significant variations in these patients.

RESUMEN

BACKGROUND: Sepsis is associated with a highest mortality rate in the ICU. Present study tests the efficacy of combined therapy with vitamin C, hydrocortisone and thiamine (combined therapy) in the ovine model of sepsis induced by Pseudomonas aeruginosa. In this study, sepsis was induced in sheep by instillation of Pseudomonas aeruginosa (1 × 1011 CFU) into the lungs via bronchoscope, under anesthesia. Nine hours after injury, intravenous infusion of vitamin C (0.75 g every 6 h), hydrocortisone (25 mg every 6 h), and thiamine (100 mg every 12 h) or saline was given to the treatment and control groups. Cardiopulmonary variables were recorded. RESULTS: The survival rate was 16.7% in control and 33.3% in treatment groups. In the control group, mean arterial pressure dropped from 93.6 ± 8.6 to 75.5 ± 9.7 mmHg by 9 h, which was not affected by the combined therapy. Pulmonary dysfunction was not attenuated by the combined therapy either. The combined therapy had no effect on increased extravascular lung water content and fluid effusion into thoracic cavity. The bacterial number in the bronchoalveolar lavage fluid was significantly increased in the treatment group than the control group. The blood bacterial number remained comparable between groups. CONCLUSIONS: Combined vitamin C, hydrocortisone, and thiamine did not attenuate severity of ovine sepsis.

RESUMEN

BACKGROUND: In adults, cortisol levels show a pronounced 24-hour rhythm with a peak in the early morning. It is unknown at what age this early-morning peak in cortisol emerges during infancy, hampering the establishment of optimal dosing regimens for hydrocortisone replacement therapy in infants with an inborn form of adrenal insufficiency. Therefore, we aimed to characterize daily variation in salivary cortisol concentration across the first year of life. METHODS: We conducted a systematic review followed by an individual participant data meta-analysis of studies reporting on spontaneous (i.e., not stress induced) salivary cortisol concentrations in healthy infants aged 0-1 year. A one-stage approach using linear mixed-effects modelling was used to determine the interaction between age and time of day on cortisol concentrations. FINDINGS: Through the systematic review, 54 eligible publications were identified, reporting on 29,177 cortisol observations. Individual participant data were obtained from 15 study cohorts, combining 17,079 cortisol measurements from 1,904 infants. The morning/evening cortisol ratio increased significantly from 1.7 (95% CI: 1.3-2.1) at birth to 3.7 (95% CI: 3.0-4.5) at 6-9 months (p < 0.0001). Cosinor analysis using all available data revealed the gradual emergence of a 24-hour rhythm during infancy. INTERPRETATION: The early-morning peak in cortisol secretion gradually emerges from birth onwards to form a stable morning/evening ratio from age 6-9 months. This might have implications for hydrocortisone replacement therapy in infants with an inborn form of adrenal insufficiency.

RESUMEN

Chronic subdural hematomas (cSDH) are often managed with a burr-hole craniostomy and drainage, but surgery is associated with elevated mortality, morbidity, and recurrence. Despite reports of steroid use for such patients, its efficacy and feasibility are still debated. We present our patient series treated with low-dose hydrocortisone. We retrospectively reviewed data from patients treated with hydrocortisone between 2017 and 2023. Demographics, clinical and radiological data were collected. Of 27 patients identified, nine required a burr-hole craniotomy for an average volume of 120.23 cm3, average midline shift of 9 mm, and neurological deficits. Eighteen met the criteria for inclusion. The mean age was 78.5 years; 13 were male. None had severe symptoms requiring urgent intervention. Except for one with a Karnofsky Performance Scale score of 70, all could maintain normal activity before treatment. The mean baseline volume was 52.6 cm3. Midline shift, present in six, averaged 6.8 mm. Patients underwent treatment for an average of 5.15 months. Nine had complete resolution within 3 months, while nine required longer treatment, including one who needed 9 months for a re-bleed after a fall. Paired t-tests indicated significant reductions in hematoma volumes at the second week (p = 0.01), first month (p < 0.0001), and third month (p < 0.0001) of treatment. No complications occurred and the post-treatment Karnofsky scores ranged from 90 to 100. Treatment for cSDH should be tailored to the patient. Low-dose hydrocortisone is safe and effective in asymptomatic patients, those with mild to moderate symptoms, and those who are either unsuitable for or decline surgical intervention.

RESUMEN

OBJECTIVE: Adrenal insufficiency (AI) is characterized by increased mortality compared to general population, mainly due to cardiovascular disease. Conventional glucocorticoid (GC) replacement therapy has a role in determining the increased mortality risk. Primary outcome of the current study was to evaluate the impact of 10 years of conventional GCs and DR-HC on body weight changes in treatment-naive patients with AI. Secondary outcomes were changes from baseline to 5 and 10 years in anthropometric and metabolic profile, insulin sensitivity, cardiovascular, and bone parameters. DESIGN AND METHODS: We prospectively randomized 42 patients to conventional GCs (cortisone acetate or hydrocortisone) and 44 to DR-HC (1:1). Anthropometric, metabolic, cardiovascular, and bone parameters were evaluated at baseline and after 5 and 10 years of follow-up. This trial is registered at ClinicalTrials.gov NCT06260462. RESULTS: At 10 years of follow-up, patients with conventional GCs had significantly higher values of BMI (P = .031), waist circumference (P = .047), systolic blood pressure (P = .039), total and LDL cholesterol (P = .041 and P = .042), HbA1c (P = .040), HOMA-IR (P = .006), AUC2h of glucose (P < .001), thickness of the interventricular septum in diastole and of the posterior wall (both P < .001) and significantly lower values of oral disposition index (P = .001) and ISI-Matsuda (P < .001), lumbar spine T score (P = .036), and femoral neck Z score (P = .026), compared to patients treated with DR-HC. CONCLUSIONS: In patients with treatment-naive AI, 10 years of conventional GC treatment is associated with a worsening of metabolic, insulin-sensitivity, cardiac, and bone outcomes, while DR-HC had no impact on them achieving a lower risk of developing comorbidities.

RESUMEN

The objective of the conducted research was to design 2 mm orodispersible minitablets of pediatric doses of hydrocortisone (0.5 mg; 1.0 mg) with desirable pharmaceutical properties and eliminate the sensation of a bitter taste using preparation of solid dispersion by ball mill. Hydrocortisone was selected as the model substance, as it is widely utilized in the pediatric population. ODMTs were prepared by compression (preceded by granulation) in a traditional single-punch tablet machine and evaluated using pharmacopoeial tests, DSC, and FTIR analysis. The methods used to evaluate the effectiveness of the taste-masking effect included in vivo participation of healthy volunteers, in vitro drug dissolution and utilization of an analytical device-"electronic tongue". The research employed a preclinical animal model to preliminary investigate the bioequivalence of the designed drug dosage form in comparison to reference products. The study confirmed the possibility of manufacturing good-quality hydrocortisone ODMTs with a taste-masking effect owing to the incorporation of a solid dispersion in the tablet mass.

RESUMEN

Background: Children with Congenital Adrenal Hyperplasia (CAH) have a higher chance of hypertension. The likelihood of hypertension is higher in CAH children who get fludrocortisone medication and have an over-suppression. Plasma renin activity (PRA) is a sensitive indicator when the fludrocortisone dose is insufficient. The objective of this study is to assess the relationship between plasma renin activity with hypertension in 21-hydroxylase-deficient (21-OHD) CAH children. Methods: This cross-sectional observational analytical study was conducted in 2019 at the Pediatric Endocrinology Outpatient Clinic in Dr. Cipto Mangunkusumo Hospital (RSCM), Jakarta, Indonesia. The subjects were 21-OHD CAH children, aged >6 months to 18 years who had already taken hydrocortisone with or without fludrocortisone for at least 6 months, and were divided into hypertension and non-hypertension groups. The subjects were selected by a consecutive sampling method. Data was analyzed using SPSS software (version 23.0) with unpaired t test analysis and multiple logistic regression test. Statistical significance was achieved if P<0.05. Results: Forty 21-OHD CAH patients were included, and 20 subjects (50%) had hypertension. A higher incidence of hypertension was found in salt-wasting CAH than in simple virilizing types (59.3% vs 30.8%). There was a significant mean difference in PRA levels between hypertension and non-hypertension groups in salt-wasting patients (P=0.016). A significant difference between the last dose of hydrocortisone with the number of hypertension patients in salt-wasting patients (P=0.032) was found, and low PRA levels showed a 1.09 times higher risk of hypertension. Conclusion: Children with salt-wasting CAH with low PRA levels had a higher risk of getting hypertension.

RESUMEN

Hydrocortisone succinate (1) is a synthetic anti-inflammatory drug and key intermediate in the synthesis of other steroidal drugs. This work is based on the fungal biotransformation of 1, using Monascus purpureus and Cunninghamella echinulata strains. Comopound 1 was transformed into four metabolites, identified as hydrocortisone (2), 11ß-hydroxyandrost-4-en-3,17-dione (3), Δ1-cortienic acid (4), and hydrocortisone-17-succinate (5), obtained through side chain cleavage, hydrolysis, dehydrogenation, and oxidation reactions. These compounds have previously been synthesized either chemically or enzymatically from different precursors. Though this is not the first report on the biotransformation of 1, but it obviously is a first, where the biotransformed products of compound 1 have been characterized structurally with the help of modern spectroscopic techniques. It is noteworthy that these products have already shown biological potential, however a more thorough investigation of the anti-inflammatory properties of these metabolites would be of high value. These results not only emphasize upon the immense potential of biotransformation in catalysis of reactions, otherwise not-achievable chemically, but also holds promise for the development of novel anti-inflammatory compounds.
