    Tumor necrosis factor-alpha inhibitors (TNF-i) are commonly used to treat immune-mediated diseases such as psoriasis, psoriatic arthritis (PsA), inflammatory bowel disease (IBD), spondyloarthritis (SpA) and rheumatoid arthritis (RA). However, paradoxical psoriasis induced by TNF-i has been described and is not uncommon, particularly with infliximab and etanercept. The presentation of TNF-i-induced psoriasis is most commonly plaque or palmoplantar morphology. Optimal treatment strategies for recalcitrant psoriatic disease are not well understood. In this case series, we report three patients with TNF-i-induced psoriasis who were treated with upadacitinib and experienced complete resolution of their psoriatic eruptions. The efficacy of Janus kinase inhibitors (JAK-i) is possibly explained by mechanisms involving uncontrolled production of type 1 IFNs as well as increases in IL-23 and T-helper 17 cells upstream of relevant JAK/STAT pathways. We also offer a proposed treatment algorithm that includes the use of JAK-i as a promising management option in patients with recalcitrant disease. However, larger studies are needed to confirm the efficacy and safety of JAK-i in this patient population. J Drugs Dermatol. 2024;23(2): doi:10.36849/JDD.7645.

    Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF01:24

    Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

    Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

    Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

    Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

    Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

    Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

    Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

    Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
    These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

    Inflammatory Bowel Disease IV: Pharmacological Management

    Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

    Drugs for Treatment of Ulcerative Colitis in IBD

    Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...
