Case Report: Borderline Lepromatous Leprosy Therapy Complicated by Type 1 Leprosy Reaction and Adverse Reactions with Dapsone and Clofazimine
Am J Trop Med Hyg. 2024 Jan 23:tpmd220637. doi: 10.4269/ajtmh.22-0637. Online ahead of print.ABSTRACTLeprosy is a global health issue, causing long-term functional morbidity and stigma. Rapid diagnosis and appropriate treatment are important; however, early diagnosis is often challenging, especially in nonendemic areas. Here, we report a case of borderline lepromatous leprosy accompanied by dapsone-induced (neutropenia, anemia, and methemoglobinemia) and clofazimine-induced (skin discoloration and ichthyosis) side effects and type 1 leprosy reactions during administration of the multidrug therapy. The patient completely re...

Linear IgA bullous dermatosis associated with immunotherapy
We present the case of a 67-year-old woman with metastatic ovarian cancer receiving anti-PD1 and anti-CTLA4 with new onset pruritic tense bullae to the trunk, hands, elbows (in annular distribution) that occurred after immunotherapy. Skin biopsy showed subepidermal blister with abundant neutrophils on H&E histology, and linear IgA staining at the basement membrane on direct immunofluorescence consistent with the diagnosis of LABD. The condition did not improve on initial prednisone taper, but blisters rapidly resolved a few days after initiation of dapsone... (Source: Dermatology Online Journal)

Treatment of Pyoderma Gangrenosum
Pyoderma gangrenosum is a rare neutrophilic dermatosis that results in painful cutaneous ulcers and is frequently associated with underlying hematologic disorders, inflammatory bowel disease, or other autoimmune disorders. Pathogenesis involves an imbalance between proinflammatory and anti-inflammatory mediators, leading to tissue damage from neutrophils. First-line treatment options with the greatest evidence include systemic corticosteroids, cyclosporine, and tumor necrosis factor alpha inhibitors. Other steroid-sparing therapies such as dapsone, mycophenolate mofetil, intravenous immunoglobulin, and targeted biologic or...

Evaluation of dapsone and its synthetic derivative DDS ‑13 in cancer < em > in  vitro < /em >
The objectives of the present study were to evaluate the anticancer activity of both DDS and DDS-13 and to identify the physicochemical and pharmacokinetic properties of DDS-13. The results showed that DDS-13 presented a cytotoxic effect in the DU145 cell line (IC50=19.06 µM), while DDS showed a cytotoxic effect on both the DU145 (IC50=11.11 µM) and HeLa (IC50=13.07 µM) cell lines. DDS-13 appears to be a good cytotoxic candidate for the treatment of prostate cancer, while DDS appears to be a good candidate for both cervical and prostate cancer. Neither candidate showed a cytotoxic effect in non-cancerous cells. The diff...
