Schmidt´s syndrome found by tan: a case report.

Addison´s disease can form part of type 2 autoimmune polyglandular syndrome. The article reports the case of a 41-year-old female patient with hypothyroidism and vitiligo, who came to the emergency department complaining of asthenia that had worsened in recent months, as well as anorexia, nausea, and weight loss (6 kg in a year). Cutaneous hyperpigmentation was the main finding on physical examination, together with vitiligo lesions on the face, hands, and armpits. Further study revealed a low serum cortisol level, normal urine-free cortisol, and an elevated adrenocorticotropic hormone (ACTH). Antiperoxidase antibodies and 17-alpha-hidroxylase antibodies were both positive. Treatment was started with prednisolone and fludrocortisone, and a good clinical response was obtained. This case report aims to draw attention to the high level of clinical suspicion required to diagnose Addison´s disease and the need to screen actively for other potentially associated autoimmune diseases that may be associated.

Protracted Febrile Myalgia Syndrome: A Rare and Difficult Manifestation of Familial Mediterranean Fever.

OBJECTIVE: Protracted febrile myalgia syndrome (PFMS) is characterized by severe myalgia, fever, abdominal pain, and arthralgia/arthritis episodes lasting for several weeks in patients with familial Mediterranean fever. Treatment options include nonsteroidal anti-inflammatory drugs, corticosteroids, and anti-interleukin-1 therapy. This study aimed to share our experiences of PFMS so as to shed light on this rare and elusive condition. METHODS: This cross-sectional analysis included 17 patients diagnosed with PFMS at our pediatric rheumatology clinic between January 2018 and September 2023. RESULTS: In our clinic, 17 (1%) of 1663 familial Mediterranean fever patients presented with PFMS, and it was the initial manifestation in 10 patients (58.8%) in the cohort. Eight of the 17 patients had an M694V homozygous mutation in the MEFV gene. A magnetic resonance imaging showed myositis and fasciitis in just 1 patient, and myositis alone was evident in 5 others. Symptoms improved in 2 patients with nonsteroidal anti-inflammatory drugs, whereas prednisolone improved symptoms in 12 patients and anakinra was required in 3 patients. Patients who received anakinra had another severe attack and required long-term anakinra or canakinumab. CONCLUSIONS: Syndrome for PFMS is difficult to recognize as it can sometimes be the first manifestation of familial Mediterranean fever. The syndrome is not accompanied by fever in some patients, even though the word febrile is part of its name. Most patients respond dramatically to nonsteroidal anti-inflammatory drugs or corticosteroids. In some patients with PFMS, long-term anakinra or canakinumab treatment may be more useful in preventing severe attacks of PFMS than short-term (5 to 7 days) anakinra treatment.

A bio-predictive release assay for liposomal prednisolone phosphate.

Predictive performance assays are crucial for the development and approval of nanomedicines and their bioequivalent successors. At present, there are no established compendial methods that provide a reliable standard for comparing and selecting these formulation prototypes, and our understanding of the in vivo release remains still incomplete. Consequently, extensive animal studies, with enhanced analytical resolution for both, released and encapsulated drug, are necessary to assess bioequivalence. This significantly raises the cost and duration of nanomedicine development. This work presents the development of a discriminatory and biopredictive release test method for liposomal prednisolone phosphate. Using model-informed deconvolution, we identified an in vivo target release. The experimental design employed a discrete L-optimal configuration to refine the analytical method and determine the impact of in vitro parameters on the dosage form. A three-point specification evaluated the key phases of in vivo release: early (T-5%), intermediate (T-20%), and late release behavior (T-40%), compared to the in vivo release profile of the reference product, NanoCort®. Various levels of shear responses and the influence of clinically relevant release media compositions were tested. This enabled an assessment of the effect of shear on the release, an essential aspect of their in vivo deformation and release behavior. The type and concentration of proteins in the medium influence liposome release. Fetal bovine serum strongly impacted the discriminatory performance at intermediate shear conditions. The method provided deep insights into the release response of liposomes and offers an interesting workflow for in vitro bioequivalence evaluation.

Sclerosing mesenteritis as a cause of porto-mesenteric vascular obstruction.

A woman in her 20s presented with haematemesis, post-prandial abdominal pain, weight loss and anaemia. Imaging revealed a non-enhancing mass in the retroperitoneal space along the mesenteric plane, encasing the porto-mesenteric vasculature. Endoscopy showed oesophageal varices. She was diagnosed with sclerosing mesenteritis, causing extrinsic compression of the portal vein and superior mesenteric artery. She underwent endoscopic variceal ligation and received prednisolone and tamoxifen. After 3 months, her post-prandial pain improved, and she did not have further bleeding episodes.

Glucocorticoid-induced acute diuresis in rats in relation to the reduced renal expression of sodium-dependent cotransporter genes.

Although several studies have shown that glucocorticoids exert diuretic effects in animals and humans, the underlying mechanism responsible for the acute diuretic effect remains obscure. Here we examined the mechanism in terms of gene-expression. We observed that glucocorticoids, including dexamethasone (Dex) and prednisolone (PSL), acutely induced diuresis in rats in a dose-dependent manner. Free water clearance values were negative after Dex or PSL treatment, similar to those observed after treatment with osmotic diuretics (furosemide and acetazolamide). Dex significantly increased the urinary excretion of sodium, potassium, chloride, glucose, and inorganic phosphorus. Renal microarray analysis revealed that Dex significantly altered the renal expression of genes related to transmembrane transport activity. The mRNA levels of sodium/phosphate (NaPi-2a/Slc34a1, NaPi-2b/Slc34a2, and NaPi-2c/Slc34a3) and sodium/glucose cotransporters (Sglt2/Slc5a2) were significantly reduced in the Dex-treated kidney, being negatively correlated with the urinary excretion of their corresponding solutes. Dex did not affect renal expression of the natriuretic peptide receptor 1 (Npr1) gene, or the expression, localization, and phosphorylation of aquaporin-2 (AQP2), a water channel protein. These findings suggest that the acute diuretic effects of glucocorticoids might be mediated by reduced expression of sodium-dependent cotransporter genes.

[Autoimmune hepatitis developed after COVID-19 vaccination and ameliorated temporarily but relapsed or stopped improving, and finally resolved by steroid therapy:a report of three cases].

The severe acute respiratory syndrome coronavirus 2 vaccine has contributed to infection control and the prevention of complications due to coronavirus disease 2019 (COVID-19). Conversely, the COVID-19 vaccine has been associated with adverse effects due to liver injury caused by autoimmunity or drugs. To date, Japanese journals have only published five reports of autoimmune liver damage associated with the COVID-19 vaccination. Although the pathogenic mechanism has not yet been fully elucidated, corticosteroids or azathioprine have shown effectiveness in certain patients. However, there have been cases of liver injury resulting in deaths. Here, we encountered three patients who developed autoimmune hepatitis (AIH) within 10 days following vaccination. All three patients were treated with prednisolone (PSL) and achieved remission. However, the serum alanine aminotransferase levels in all cases were observed to either increase or cease to improve during the therapeutic course before PSL administration. It is therefore imperative to closely monitor liver injury after the COVID-19 vaccination. In cases where AIH is suspected and a recurrence of liver dysfunction occurs, PSL may be administered. Future considerations should not only encompass the underlying mechanism by which autoimmunity contributes to the development of liver injury following COVID-19 vaccination but also the optimal treatment period for PSL and the long-term prognosis of AIH after COVID-19 vaccination.

Comparison of the Prevention of Esophageal Stricture Between Oral Prednisolone Alone and Oral Prednisolone Combined with Nasogastric Tube in Superficial Esophageal Cancer After Endoscopic Submucosal Dissection.

BACKGROUND/AIMS:  There is a lack of effective and safe methods for preventing esophageal stricture after large endoscopic submucosal dissection (ESD) in patients with superficial esophageal cancer. We aimed to compare the effectiveness of oral prednisolone alone versus a combination of oral prednisolone and nasogastric tube in preventing esophageal stricture following extensive ESD. MATERIALS AND METHODS:  We retrospectively gathered clinical data from a single center on patients with early esophageal cancer who underwent ESD. Patients were categorized into 2 groups: the steroid group (receiving only oral prednisolone) and the steroid+nasogastric tube retention (NGT) group. We analyzed the incidence of esophageal stricture and identified risk factors for its development. RESULTS:  The study included 79 patients, with 30 in the steroid group and 49 in the steroid+NGT group. The incidence of stricture was significantly higher in the steroid group (9/30, 30.0%) compared to the steroid+NGT group (3/49, 6.1%) (P = .004). Notably, we observed a significant difference in the stricture rates between the 2 groups, particularly in patients with a complete circumferential defect (100% and 16.7%) (P = .015). Multivariate logistic regression analysis revealed that a full circumferential defect of the esophageal mucosa (OR 12.501; 95% CI 1.907, 81.047; P = .008), invasion depth beyond the lamina propria (OR 5.635; 95% CI 1.039, 30.559; P = .045), and the absence of NGT retention (OR 12.896; 95% CI 2.099, 79.219; P = .006) were independent risk factors predicting the development of a stricture. CONCLUSION:  The combination of steroids with NGT retention is more effective than using oral steroids alone in preventing esophageal stricture after extensive ESD.

Preventing long-term disability in CIDP: the role of timely diagnosis and treatment monitoring in a multicenter CIDP cohort.

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an inflammatory disease affecting the peripheral nerves and the most frequent autoimmune polyneuropathy. Given the lack of established biomarkers or risk factors for the development of CIDP and patients' treatment response, this research effort seeks to identify potential clinical factors that may influence disease progression and overall treatment efficacy. METHODS: In this multicenter, retrospective analysis, we have screened 197 CIDP patients who presented to the University Hospitals in Düsseldorf, Berlin, Cologne, Essen, Magdeburg and Munich between 2018 and 2022. We utilized the respective hospital information system and examined baseline data with clinical examination, medical letters, laboratory results, antibody status, nerve conduction studies, imaging and biopsy findings. Aside from clinical baseline data, we analyzed treatment outcomes using the Standard of Care (SOC) definition, as well as a comparison of an early (within the first 12 months after manifestation) versus late (more than 12 months after manifestation) onset of therapy. RESULTS: In terms of treatment, most patients received intravenous immunoglobulin (56%) or prednisolone (39%) as their first therapy. Patients who started their initial treatment later experienced a worsening disease course, as reflected by a significant deterioration in their Inflammatory Neuropathy Cause and Treatment (INCAT) leg disability score. SOC-refractory patients had worse clinical outcomes than SOC-responders. Associated factors for SOC-refractory status included the presence of fatigue as a symptom and alcohol dependence. CONCLUSION: Timely diagnosis, prompt initiation of treatment and careful monitoring of treatment response are essential for the prevention of long-term disability in CIDP and suggest a "hit hard and early" treatment paradigm.

Methylprednisolone pulse and prednisolone for intensification of primary treatment in Kawasaki disease patients at high risk of treatment resistance: a multicenter prospective cohort study.

The purpose of this study is to determine whether adding intravenous methylprednisolone pulse (IVMP) to primary adjunctive prednisolone with intravenous immunoglobulin (IVIG) improves treatment resistance and coronary artery aneurysms (CAA) in patients with Kawasaki disease (KD) with a high risk of treatment resistance. This multicenter, prospective, observational study was conducted at 28 hospitals in Japan from October 2016 to June 2020. For patients predicted to be resistant to treatment based on a Kobayashi score ≥ 5 and total bilirubin ≥ 1.0 mg/dL, each hospital independently decided to add IVMP followed by prednisolone, prednisolone alone, or nothing to the primary IVIG therapy. In total, 2856 consecutive KD patients were enrolled; of these, 399 (14.0%) were predicted to be treatment resistant. Patients who were resistant to the primary treatment and required additional treatment comprised 59%, 20%, and 26% of the IVIG-alone group, IVIG-plus-prednisolone group, and IVIG-plus-IVMP group, respectively (P < .0001). The CAA incidence (Z score ≥ 2.5) at month 1 was similar among the treatment groups (6.7%, 4.8%, and 7.3%, respectively; P = .66). CAA occurred more frequently in patients who needed third- or later-line therapy.Conclusions: Primary adjunctive corticosteroid therapy improved the treatment response and suppressed inflammation. However, the study found no benefit of adding IVMP to prednisolone therapy. Patients receiving IVIG alone achieved coronary outcomes comparable to those of patients receiving primary adjunctive corticosteroid therapy although they were more likely to require additional rescue treatment. KD inflammation should be resolved no later than the third line of additional treatment to reduce the risk of CAA.Trial registration: University Hospital Medical Information Network Clinical Trials Registry in Japan ( https://www.umin.ac.jp/ctr/index.htm ) under code UMIN000024937.

Vitamin B12 deficiency presenting as progressive blindness in a 33-year-old HIV-positive female patient on Efavirenz-based regimen: case report.

Optic neuritis is a rare presentation of vitamin B12 deficiency. We describe a 33-year-old female patient living with HIV presenting with progressive loss of vision for 1 week. She had a history of severe peripheral neuropathy that was managed with vitamin B12-containing tablets approximately three years before presenting with progressive loss of vision. On examination, she had no perception of light in the left eye and no perception of hand motion in the right eye. The fundus in her left eye had mild blurring of disc margins. Results from tests done showed a haemoglobin of 12.9g/dl, MCV 101fl, a serum vitamin B12 of 78pmol/l, and cytomegalovirus (CMV) test showed no active disease. She was diagnosed with optic neuritis and started on 30 mg tablets of prednisolone for 1 week with slight improvement. She was then started on vitamin B12 injections 1 mg daily for 10 days and thereafter, monthly for 6 months. She reported gradual improvement and regained her sight after 5 months treatment of with Vitamin B12 injections. Ophthalmic manifestations of vitamin B12 deficiency are not common and may present without haematological signs therefore, a high index of suspicion is required for early diagnosis and management of vitamin B12 deficiency.

Remission of diabetes mellitus induced by prednisolone in combination with cyclosporine toxicity in a cat.

A 6-year-old spayed female domestic short-hair cat was presented for primary complaints of anorexia and lethargy. The cat was being treated with cyclosporine (25 mg/cat, PO q24h) and prednisolone (1 mg/kg, PO q12h) for feline hypersensitivity dermatitis and inflammatory bowel disease for 1 year, wherein prednisolone was withdrawn 2 weeks prior to presentation. At presentation, dehydration, hyperglycaemia, ketonaemia, increased fructosamine, glucosuria, ketonuria and metabolic acidosis were observed. The cat was diagnosed with diabetic ketoacidosis (DKA). Immediate treatments with insulin continuous-rate infusion and intravenous fluid therapy were initiated. A serum cyclosporine concentration was >2100 ng/mL, indicating cyclosporine toxicity. Cyclosporine was discontinued immediately. The cat's acidosis and ketonaemia were resolved within a week, allowing a switch from insulin continuous-rate infusion to subcutaneous glargine (1 IU/cat), which was eventually discontinued due to persistent normoglycaemia 12 days after initial presentation. Hyperglycaemia was not observed for 28 days thereafter without insulin, indicating remission of diabetes mellitus. This report suggests that using prednisolone, particularly immune suppressive doses, could be problematic in cats receiving long-term cyclosporine therapy. Additionally, diabetic cats receiving immune-suppressive agents can possibly achieve diabetic remission after surviving DKA through regular monitoring of blood glucose concentration, elimination of prednisolone and intensive blood glucose management.

Paradoxical development of Kimura's disease in a patient treated with mepolizumab for bronchial asthma.

A male patient in his early 30s was diagnosed with bronchial asthma 3 years previously. He responded well to inhaled corticosteroids and long-acting beta-agonists. Approximately 18 months from the onset, the patient reported worsening symptoms. These symptoms included severe functional limitations, requiring frequent exposure to high-dose prednisolone. Mepolizumab was added to the treatment, leading to optimal control of bronchial asthma. Despite receiving seven doses of mepolizumab at monthly intervals, the patient developed cervical and postauricular lymphadenopathy and subcutaneous swelling of soft tissue. A cervical lymph node biopsy confirmed the diagnosis of Kimura disease. Following treatment with oral glucocorticoids and methotrexate, the patient experienced a complete resolution of symptoms. He has been in remission and off oral prednisolone for the last 13 months. In this case, we highlight the development of Kimura disease in a patient undergoing mepolizumab treatment.

PREDNISOLONE EYE DROPS AS A POTENTIAL TREATMENT IN NONNEOVASCULAR PACHYCHOROID-RELATED DISEASES.

PURPOSE: To investigate the functional and structural outcomes after treatment with prednisolone eye drops in the following pachychoroid-related diseases: chronic central serous chorioretinopathy, pachychoroid pigment epitheliopathy, and peripapillary pachychoroid syndrome. METHODS: In this retrospective study, 54 eyes of 48 patients with pachychoroid-related disease were treated with prednisolone acetate 1% eye drops 3 times a day. Change in macular volume and retinal central subfield thickness on optical coherence tomography was measured. In addition, the foveal or complete resolution of fluid and the change in visual acuity were studied. RESULTS: The follow-up visit was at a mean of 41.2 ± 14.5 days. In the 44 eyes with chronic central serous chorioretinopathy, a significant reduction in retinal central subfield thickness ( P < 0.001) and macular volume ( P < 0.001) was observed. Foveal intra- or subretinal fluid resolved completely in 22% of the eyes. In the 8 peripapillary pachychoroid syndrome eyes, a reduction in the nasal retinal thickness was observed ( P = 0.025). One of the 2 pachychoroid pigment epitheliopathy eyes showed structural improvement. No significant change in visual acuity was observed in any of the pachychoroid spectrum diseases. CONCLUSION: In patients with chronic central serous chorioretinopathy, peripapillary pachychoroid syndrome, and pachychoroid pigment epitheliopathy, anatomical improvement was observed after therapy with prednisolone eye drops. Visual acuity did not change significantly.

Cancer-associated neuromyelitis optica spectrum disorder: a case report with literature review.

Neuromyelitis optica spectrum disorders (NMOSD) is one of autoimmune inflammatory diseases and is characterized by area postrema syndrome, brainstem syndrome, optic neuritis, and/or myelitis. Typical myelitis is longitudinally extended transverse myelitis (LETM) which extends over three vertebral bodies. Several previous case reports have suggested association between cancer and NMOSD. A 50-year-old woman had breast cancer and underwent mastectomy and, 10 months later, she had developed acutely progressive dysbasia. Spine MRI showed LETM in 13 vertebrae length and blood test revealed positive anti-aquaporin 4 (anti-AQP4) antibody based on enzyme-linked immunosorbent assay with index of over 40. She was treated by intravenous methylprednisolone, plasma exchange, and intravenous immunoglobulin, followed by oral prednisolone. The condition had mostly recovered after the treatment. A small population of NMOSD has the aspect of paraneoplastic neurological syndrome. The age of onset in patients with cancer-associated NMOSD tends to be higher than that in individuals with NMOSD due to any causes of NMOSD.

Remission of hypersensitivity pneumonitis after allogeneic hematopoietic stem cell transplantation.

A 50-year-old man was diagnosed with hypersensitivity pneumonitis caused by the environment of his bar owing to worsening symptoms, laboratory test results, and computed tomography images after an environmental inhalation challenge test. His hypersensitivity pneumonitis exacerbated despite receiving prednisolone 20 mg/day. The patient underwent allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen-matched unrelated donor for myelodysplastic syndrome. No exacerbation of hypersensitivity pneumonitis was observed after HSCT. An environmental inhalation challenge test involving exposure to his bar confirmed the remission of hypersensitivity pneumonitis after HSCT. This case demonstrates that hypersensitivity pneumonitis can be remitted by HSCT.

The remarkable antitumor efficacy of corticosteroid treatment in patients with refractory thymomas.

BACKGROUND: Some case reports have found that corticosteroid treatments shrunk thymoma lesions remarkably after the failure of chemotherapy or surgery. However, few studies have comprehensibly evaluated the antitumor effects of corticosteroids in patients with invasive thymomas. METHODS: We reviewed the medical records of 13 consecutively enrolled patients with locally advanced or metastatic thymomas treated via corticosteroid monotherapies from January 2010 to March 2021 in our institute. A Cox's proportional hazard model and the Kaplan-Meier method were used to identify factors associated with survival. RESULTS: The median follow-up time was 26 months (range, 13-115 months). The median initial dose of corticosteroid was 0.90 mg/kg/day prednisolone equivalent (range, 0.4-1.1 mg/kg/day). Of the 13 cases, 7 (53.8%, 95% CI: 0.25-0.81) exhibited a partial response and 5 (38.5%, 95% CI: 0.14-0.68) stable disease. The median progression-free survival was 5.7 months [95% confidence interval (CI): 1.5-9.6 months]. The median overall survival was 25.3 months (95% CI: 7.1-not attained). The median duration of corticosteroid use was 3 months (range, 1-64 months). Patients with WHO subtype B thymomas exhibited a better overall response rate to corticosteroids than did patients with other disease subtypes (75%, 95% CI: 0.19-0.99). Adverse events of Grade 3 or more were not observed. CONCLUSIONS: Corticosteroids are clinically valuable for patients with thymomas.

Serum bile acids profiles are altered without change of the gut microbiota composition following a seven-day prednisolone therapy in severe alcoholic hepatitis.

Severe Alcoholic Hepatitis (sAH) is an acute form of liver injury caused by chronic and heavy alcohol drinking. A one-month corticosteroids course is the only sAH reference treatment, and its interactions with the Gut Microbiota (GM), which is a key contributor to liver injury, remain unknown. To evaluate the evolution of the GM in sAH patients, we retrospectively investigated the composition of the GM of 27 sAH patients at the Amiens University Hospital before (D0) and after (D7) a 7-day corticotherapy course using fecal metagenomics sequencing. We also quantified fecal Short-Chain Fatty Acids (SCFA) and fecal and serum Bile Acids (BA), as well as serum Lipopolysaccharide-Binding Protein (LBP). Overall, the community and taxonomical analyses did not reveal any GM evolution between D0 and D7, nor did the SCFA profiles analysis. However, in serum but not fecal samples, the ratio of glyco-conjugated to tauro-conjugated BA was significantly reduced at D7, independently of the response to treatment, while two BA were enriched in non-responder patients. LBP concentration significantly diminished between D0 and D7, which may indicate an improvement of the gut barrier. The stability of the GM of sAH is interesting in the perspective of new treatments based on GM modulation.

There is a gap in the understanding of the effects of corticosteroids on the gut microbiota of severe alcoholic hepatitis patients.In this study, the composition of the Gut Microbiota of sAH patients treated with prednisolone remains unchanged after 7 days of prednisolone treatment.Short-Chain Fatty Acid profiles are not impacted by the treatment, while Bile Acids profiles change in serum but not in stool samples.Responders and non-responders show different lipopolysaccharide-binding protein serum concentration evolution across time, as well as distinct Bile Acid profiles.

Rheumatoid pleurisy confirmed by biopsy of a chest wall nodule by thoracoscopy under local anaesthesia.

Rheumatoid pleurisy is common in patients with rheumatoid arthritis, but distinguishing it from other diseases, such as heart failure and tuberculous pleurisy, is often difficult. A man in his 70s with stable rheumatoid arthritis presented with cardiac enlargement and bilateral pleural effusion on chest radiography. Pleural fluid studies showed lymphocytosis, adenosine deaminase level of 51.6 U/L and rheumatoid factor level of 2245.3 IU/mL, suggestive of rheumatoid pleurisy and tuberculous pleurisy. Thoracoscopy under local anaesthesia revealed erythema of the parietal pleura, small papillary projections and fibrin deposits. H&E-stained biopsy specimens showed inflammatory granulomas with strong lymphocytic infiltration and non-caseating granulomas. He was diagnosed with rheumatoid pleurisy. His symptoms improved with 30 mg of prednisolone. This study highlights that biopsy using thoracoscopy under local anaesthesia effectively diagnoses rheumatoid pleurisy, which may be challenging to diagnose.
