BACKGROUND: In this article, we present a clinical case of refractory septic shock resulting from intestinal perforation treated with high doses of vasopressin and hydrocortisone during emergency surgery. The use of such high doses of vasopressin for this type of shock is not described in the literature. CASE PRESENTATION: A 49-year-old white woman with grade III obesity, Crohn's disease, and an intestinal perforation presented with refractory septic shock. Initially, a low dose of vasopressin was used...

Background: Magnetic resonance imaging (MRI) of the spine is the preferred diagnostic tool for pathologic conditions affecting the spine. However, in patients receiving epidural corticosteroid injection (ESI) for treatment of spinal diseases, there is a possibility of misreading of MR images because of air or fluid in the epidural space after the injection. Therefore, we defined the characteristics of abnormal changes in MRI findings following an ESI in patients with low back pain. Methods: We reviewed the medical records of 133 patients who underwent MRI of the lumbar spine within 7 days after ESI between 2006 and 2015...

PURPOSE OF REVIEW: In this review, we will integrate recent knowledge on endoplasmic reticulum (ER) stress and allergy, thereby highlighting the therapeutic potential of ER stress in the context of precision medicine for allergic diseases. RECENT FINDINGS: Emerging evidence suggests that allergic diseases are very heterogeneous having numerous endotypes. This leads to the new era of modern medicine, which assumes that a particular endotype-driven therapy, called precision medicine, would be more efficacious in a specific group of patients rather than in all patients...

Background: Abiraterone acetate is an androgen synthesis inhibitor approved for the treatment of castration-resistant prostate cancer (CRPC). Although co-administration of either prednisone or prednisolone at 10 mg/d has been recommended to reduce the risk of abiraterone-induced hyperaldosteronism (notably hypokalemia) and to give adjunctive pain relief effects, whether these glucocorticoids can be substituted by dexamethasone remains unknown. Methods: We performed a retrospective review of medical records of patients who were given abiraterone for the treatment of CRPC with either prednisolone (ABI/PSL) 10 mg/d or dexamethasone (ABI/DEX) 0...

BACKGROUND: Henoch-Schönlein purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis involving the capillaries and by the deposition of IgA immune complexes. An association between HSP and atypical bacteria is uncommon in children. METHODS AND RESULTS: Here we report three cases of children, aged 5, 4 and 16 years, who were diagnosed with HSP associated with Mycoplasma pneumoniae or Chlamydia pneumoniae infection. In all presented cases, persistent cutaneous manifestations and abdominal pain were resistant to antibiotics and corticosteroids, but resolved during 48 h after the introduction of dapsone...

INTRODUCTION: Hepatotoxicity from T-cell checkpoint blockade is an increasingly common immune-related adverse event, but remains poorly characterised and can be challenging to manage. Such toxicity is generally considered to resemble autoimmune hepatitis, although this assumption is extrapolated from limited clinicopathological reports of anti-cytotoxic T-lymphocyte-associated protein 4-induced hepatotoxicity. METHODS: Here we report, with full clinicopathological correlation, three cases of T-cell checkpoint inhibitor-induced hepatotoxicity associated with anti-programmed cell death protein 1 agents...

FK506 binding protein of 51 kDa (FKBP51) is a heat shock protein 90 (Hsp90) co-chaperone involved in the regulation of steroid hormone receptors activity. It is known for its role in various regulatory pathways implicated in mood and stress-related disorders, cancer, obesity, Alzheimer's disease and corticosteroid resistant asthma. It consists of two FKBP12 like active peptidyl prolyl isomerase (PPIase) domains (an active FK1 and inactive FK2 domain) and one tetratricopeptide repeat (TPR) domain that mediates interaction with Hsp90 via its C-terminal MEEVD peptide...

The incidence of oral candidosis has increased in recent years due to the escalation in HIV-infection, cancer treatments, organ transplantation, and diabetes. In addition, corticosteroid use, dentures, and broad-spectrum antibiotic use have also contributed to the problem. Treatment of oral candidosis has continued to be problematic because of the potential toxicity of antifungals in clinical use, and, above all, development of drug resistance among patients. In this study, the antifungal effect of magnolol was investigated against 64 strains of Candida spp...

Acute graft versus host disease (aGVHD) remains an excessive cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Primary treatment consists of high-dose corticosteroids, but a small group of patients develop steroid refractory disease and their prognosis is especially poor. There is experimental evidence that co-existing inflammation aggravates aGVHD. Since C-reactive protein (CRP) is a systemic inflammatory marker, we aimed to investigate whether plasma CRP concentrations at aGVHD diagnosis could predict the risk of failing first-line therapy and developing steroid refractory disease...

Angioedema is the swelling of mucosal and sub-mucosal tissue. Typically, it manifests as the swelling of the face, lips, and tongue. Angioedema can be severe and life threatening when it involves the respiratory tract. Drug induced allergic angioedema and drug induced non-allergic angioedema differ in their mediator, their clinical presentations, and their management. In drug induced non-allergic angioedema, symptoms are resistant to antihistamine and corticosteroid treatment. The aim of the analysis was to identify which medications are associated with drug-induced non-allergic angioedema and to understand the mechanism of action via which of these medication cause angioedema...

The genus Malassezia includes yeasts that are commonly found on the skin or hair of animals and humans as commensals and are associated with a number of skin disorders. We have previously developed an Agrobacterium tumefaciens transformation system effective for both targeted gene deletion and insertional mutagenesis in Malassezia furfur and M. sympodialis In the present study, these molecular resources were applied to characterize the immunophilin FKBP12 as the target of tacrolimus (FK506), ascomycin, and pimecrolimus, which are calcineurin inhibitors that are used as alternatives to corticosteroids in the treatment of inflammatory skin disorders such as those associated with Malassezia species...

BACKGROUND: Rapidly progressive interstitial pneumonias (RPIPs) associated with clinically amyopathic dermatomyositis (CADM) are highly resistant to therapy and have a poor prognosis. Multimodal therapies, including direct hemoperfusion using a polymyxin B-immobilized fiber column (PMX-DHP), have a protective effect on RPIPs. We evaluated the effects of PMX-DHP on CADM-associated RPIPs. METHODS: We retrospectively enrolled 14 patients with CADM-associated RPIPs and acute respiratory failure treated with PMX-DHP, corticosteroids, and immunosuppressive agents...

PURPOSE OF REVIEW: The purpose of this review is to provide an update on the use and risks of long-term corticosteroids in the management of chronic rhinosinusitis (CRS). RECENT FINDINGS: Long-term use of systemic corticosteroids is not indicated in the management of CRS due to the associated side effects and potential complications. Therefore, recent research has focused on the safety and efficacy of topical corticosteroid, particularly second-generation corticosteroids, and their modes of administration...

Imatinib has clinical activity in chronic graft-versus-host disease (cGvHD), a significant complication of allogeneic hematopoietic cell transplant. Nilotinib is a tyrosine kinase inhibitor that targets the same receptors as imatinib but with different affinities. We tested the hypothesis that nilotinib is safe and has clinical activity in cGvHD. 33 participants were enrolled in a phase 1/2 dose escalation and dose extension clinical trial of nilotinib for the treatment of steroid refractory or dependent cGvHD (ClinicalTrials...

Diabetic macular edema (DME), which is the consequence of the failed blood-retinal barrier, has become a leading cause of blindness in diabetic patients. Vascular endothelial growth factors (VEGF) and a series of inflammatory factors participate in the pathophysiology of DME. Laser photocoagulation was accepted as the first-line therapy before anti-VEGF therapy was proved to be more effective by several clinical trials. Anti-VEGF therapy has been regarded as the standard treatment, but there are still lots of cases resistant to anti-VEGF therapy...

Corticosteroids are a class of steroid hormones that are produced and disengage in the adrenal cortex. Traditionally natural and synthetic corticosteroids are used for diagnosing and treating dysfunctions of the adrenal cortex and treating inflammatory and immunological diseases. Their use is also widespread in oncological practice. Corticosteroids are indispensable in palliative care, in certain urgent oncological cases, as premedication of some chemotherapies and last but not least they have a key role in the secondary hormonal manipulations of metastatic castrate-resistant prostate cancer...
