BACKGROUND: Sarcoidosis, a multisystem inflammatory non-caseating granulomatous disease, can present with neurologic lesions in up to 10% of patients. CASE DESCRIPTION: A 57-year-old male presented with three months of worsening upper extremity radicular pain associated with dysmetria, hyperreflexia, bilateral Hoffman's, and positive Babinski signs. The contrast magnetic resonance imaging (MRI) showed a diffuse T2 signal hyperintensity and T1-enhancing 2.5 cm lesion extending sagittally between C4 and C6...

BACKGROUND AND AIM: C-reactive protein (CRP)-to-albumin ratio (CAR) is a novel score with prognostic value in inflammatory conditions. This study assessed the performance of CAR as an objective marker of disease activity and prediction of subtherapeutic infliximab trough levels in patients with inflammatory bowel disease (IBD). METHODS: A retrospective study was conducted on three different patient cohorts with IBD: patients who had (i) fecal calprotectin (FC) measurements; (ii) Mayo Endoscopic Scores; and (iii) infliximab trough levels available...

Immune reconstitution inflammatory syndrome (IRIS) has been reported in immunocompromised patients with disseminated Mycobacterium genavense . Management relies on high-dose corticosteroids. We describe two cases of late-onset corticosteroid-refractory IRIS related to disseminated infection in a HIV-positive patient and a renal transplant patient who had a favorable outcome with a monoclonal TNF-α blocker.

SIGNIFICANCE: The Wound Healing Foundation recognized the need for consensus-based unbiased recommendations for the treatment of wounds. As a first step, a consensus on the treatment of chronic wounds was developed and published in 2022.(1) The current publication on acute wounds represents the second step in this process. Acute wounds may result from any number of conditions, including burns, military and combat operations, and trauma to specific areas of the body. The management of acute wounds requires timely and evidence-driven intervention to achieve optimal clinical outcomes...

BACKGROUND/OBJECTIVES: Adverse drug reactions (ADRs) can result in morbidity, mortality, and higher healthcare costs. Given the limited information available on ADRs associated with antirheumatic medications, this study aims to analyse and compare ADR reporting for these drugs in the pharmacovigilance datasets of Western Australia (WA) and the United States (US). METHODS: Therapeutic Goods Administration provided WA pharmacovigilance data of selected antirheumatic drugs to from 1995 to 2015...

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the digestive tract usually characterized by diarrhea, rectal bleeding, and abdominal pain. IBD includes Crohn's disease and ulcerative colitis as the main entities. IBD is a debilitating condition that can lead to life-threatening complications, involving possible malignancy and surgery. The available therapies aim to achieve long-term remission and prevent disease progression. Biologics are bioengineered therapeutic drugs that mainly target proteins...

PURPOSE OF REVIEW: This review details the three new agents, including two novel mechanisms of action, approved to treat Crohn's disease in recent years. We review efficacy, safety, prescribing information, and available data on positioning these new therapies. RECENT FINDINGS: Risankizumab and upadacitinib are novel mechanisms of action approved to treat moderate to severe Crohn's disease. Risankizumab targets the cytokine interleukin-23. Upadacitinib is a selective Janus kinase-1 inhibitor approved for use in individuals who have previously failed or are intolerant to an anti-TNF agent...

PURPOSE: Describe the safety, complications, and need for urgent surgery in patients requiring inpatient rescue infliximab for acute Crohn's disease (CD) flare. BACKGROUND: Infliximab is increasingly used for patients hospitalized with acute severe ulcerative colitis as rescue therapy; however, optimal management for patients hospitalized for CD flares remains unclear. METHODS: A single-institution retrospective study of patients aged 18+ admitted from 2008 to 2020 with acute Crohn's flare requiring induction of rescue infliximab therapy...

OBJECTIVES: Acute severe colitis (ASC) occurs in up to 15 percent of children with ulcerative colitis, with a high index of morbidity and mortality. Treatment includes high-dose steroids, infliximab, and salvage therapies. Unfortunately, up to 20 percent of patients may need an urgent colectomy due to treatment failure. We report our experience using tofacitinib for the treatment of six patients. METHODS: A retrospective review of our medical electronic records was conducted...

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoimmune disease that typically develops during adolescence and primarily affects women. CRMO primarily targets the bone in arms and legs, with sporadic occurrences in the mandible. CRMO is typically managed with medical treatment, and the efficacy of surgery remains controversial. Complications of surgery include massive bleeding and potential flare-up of CRMO symptoms. Herein, we report a patient with CRMO who had lesions in the bilateral rami of the mandible treated with aesthetic mandibular angloplasty...

Background Hidradenitis suppurativa (HS) is a challenging inflammatory skin condition. Recently, many different biologics have been tested for HS, but the paucity of head-to-head comparative trials makes it difficult to determine the real value of each biological intervention. We aimed to determine the relative efficacy among biologics in treating moderate-to-severe HS throughout a network meta-analysis (NMA) and, to identify which pathogenetic pathways may be the most appropriate to target. Methods We comprehensively identified studies in 3 databases and clinicaltrials...

Acute kidney injury (AKI) is often accompanied by uremic encephalopathy resulting from accumulation of uremic toxins in brain possibly due to impaired blood-brain barrier (BBB) function. Anionic uremic toxins are substrates or inhibitors of organic anionic transporters (OATs). In this study we investigated the CNS behaviors and expression/function of BBB OAT3 in AKI rats and mice, which received intraperitoneal injection of cisplatin 8 and 20 mg/kg, respectively. We showed that cisplatin treatment significantly inhibited the expressions of OAT3, synaptophysin and microtubule-associated protein 2 (MAP2), impaired locomotor and exploration activities, and increased accumulation of uremic toxins in the brain of AKI rats and mice...

INTRODUCTION: Multiple therapies are currently available for inflammatory bowel disease (IBD); it is therefore crucial to understand patterns of drug change. This study aimed to examine the patterns of biological drug change and identify predictors of change in patients with IBD. METHODS: We performed a retrospective study of patients diagnosed with IBD who were initiated on treatment with biologics between June 2017 and October 2022. The study's primary objective was to describe biologic drug change patterns...

BACKGROUND: Ulcerative colitis (UC) is characterized in part by a dysregulated response to tissue hypoxia. While intravenous (IV) steroids are the mainstay of treatment for acute severe UC (ASUC), up to one-third of patients are refractory to steroids alone and require rescue therapy. CASE DESCRIPTION: A 71-year-old female with extensive UC on infliximab presented with abdominal pain and more than 10 bloody bowel movements per day. Her infliximab concentration was undetectable with a positive antibody level...

UNLABELLED: Ulcerative colitis (UC) is an autoimmune disease associated with both intestinal and extraintestinal manifestations. The latter may include heart complications, such as myopericarditis leading to life-threatening arrythmias. Nowadays, UC is commonly treated with biologic medications and infliximab is the first line therapy in an outpatient setting, while it is also used as rescue therapy in acute severe UC. However, it has been associated with severe immunosuppression, cytomegalovirus (CMV) reactivation and drug-induced hepatitis...

BACKGROUND AND OBJECTIVE: Although little information is available on the pharmacokinetics (PK) of monoclonal antibodies (mAbs) during pregnancy, multiple mAbs are being used during pregnancy for various indications. The aim of this systematic literature review was to characterize the PK of mAbs throughout pregnancy. METHODS: A systematic literature search was carried out in PubMed and Embase on 21 April 2023. Articles were included when information on PK or exposure parameters of mAbs in pregnant women was available...

BACKGROUND: In this nationwide study, our objective was to compare the durability of first-line biologics in ulcerative colitis (UC), categorized into monotherapy and combotherapy with immunomodulators. METHODS: We utilized data from the nationwide epi-IIRN cohort from 2005 to 2020. Durability was defined as consistent treatment without surgery. Comparisons were based on stringent propensity score-matching. RESULTS: We included 15 111 patients with UC, of whom 2322 (15%) received biologics, with a median follow-up of 7...

BACKGROUND: Stem cell transplantation is a promising therapeutic option for curing perianal fistula in Crohn's disease (CD). Anti-tumor necrotic factor (TNF) therapy combined with drainage procedure is effective as well. However, previous studies are limited to proving whether the combination treatment of biologics and stem cell transplantation improves the effect of fistula closure. AIM: This study aimed to evaluate the long-term outcomes of stem cell transplantation and compare Crohn's perianal fistula (CPF) closure rates after stem cell transplantation with and without anti-TNF therapy, and to identify the factors affecting CPF closure and recurrence...

BACKGROUND: Many patients with ulcerative colitis (UC) do not respond well to, or tolerate conventional and biological therapies. There is currently no consensus on the treatment of refractory UC. Studies have demonstrated that the selective Janus kinase 1 inhibitor upadacitinib, a small-molecule drug, is effective and safe for treating UC. However, no studies have revealed that upadacitinib is effective in treating refractory UC with primary nonresponse to infliximab and vedolizumab...

BACKGROUND: Patients with Crohn's disease (CD) who lose response to biologics experience reduced quality of life (QoL) and costly hospitalizations. Precision-guided dosing (PGD) provides a comprehensive pharmacokinetic (PK) profile that allows for biologic dosing to be personalized. We analyzed the cost-effectiveness of infliximab (IFX) PGD relative to two other dose intensification strategies (DIS). METHODS: We developed a hybrid (Markov and decision tree) model of patients with CD who had a clinical response to IFX induction...
