Abstract

The impact of new and emerging therapies on the microenvironment of primary cutaneous lymphomas (PCLs) has been recently raised in the literature. Concomitantly, novel treatments are already used or registered (dupilumab, upadacitinib) and others seem to be added to the armamentarium against atopic dermatitis. Our aim was to review the literature on interleukins 4, 13, 22, and 31, and JAK/STAT pathways in PCLs to elucidate the safety of using biologics (dupilumab, tralokinumab, fezakinumab, nemolizumab) and small molecule inhibitors (upadacitinib, baricitinib, abrocitinib, ruxolitinib, tofacitinib) in the treatment of atopic dermatitis. We summarized the current state of knowledge on this topic based on the search of the PubMed database and related references published before 21 October 2021. Our analysis suggests that some of the mentioned agents (dupilumab, ruxolitinib) and others may have a direct impact on the progression of cutaneous lymphomas. This issue requires further study and meticulous monitoring of patients receiving these drugs to ensure their safety, especially in light of the FDA warning on tofacitinib. In conclusion, in the case of the rapid progression of atopic dermatitis/eczema, especially in patients older than 40 years old, there is a necessity to perform a biopsy followed by a very careful pathological examination.

  • Emerging strategies for atopic dermatitis include microbiome modulation, neuroimmune pathway targeting, and biomarker-guided treatment selection.

    “Emerging strategies include microbiome modulation, neuroimmune pathway targeting, and biomarker-guided treatment selection, reflecting an evolving precision medicine approach in atopic dermatitis.”

    From The Cutaneous Immune Microenvironment in Selected Inflammatory Skin Diseases: Linking Histopathology, Mechanisms, and Targeted Therapy (2026) · cites this paper as [18]

    Section 2.1, “New Medications in AD” (page unavailable), describes nemolizumab targeting IL-31 signaling and acting on cutaneous sensory neurons, supporting neuroimmune pathway targeting. The passages found do not describe microbiome modulation or biomarker-guided treatment selection as emerging strategies for atopic dermatitis; searches for microbiome, microbial treatment, biomarkers, and patient selection did not establish those parts. (LLM, conf=0.86)

  • Recent real-world evidence supports the effectiveness of JAK inhibitors in moderate-to-severe atopic dermatitis, particularly in patients with inadequate response to biologic therapies.

    “Recent real-world evidence further supports the effectiveness of JAK inhibitors in moderate-to-severe atopic dermatitis, particularly in patients with inadequate response to biologic therapies [11,16,17,18,19].”

    From The Cutaneous Immune Microenvironment in Selected Inflammatory Skin Diseases: Linking Histopathology, Mechanisms, and Targeted Therapy (2026) · cites this paper as [18]

    Section 2.1, “New Medications in AD” (page unavailable), reports that JAK inhibitors were effective in phase III trials, including trials in moderate-to-severe atopic dermatitis. It does not report completed real-world effectiveness evidence or effectiveness specifically among patients who had responded inadequately to biologic therapies; the real-world upadacitinib study listed in the References was prospective. (LLM, conf=0.88)

  • These IL-17-producing populations produce IL-17A, IL-17F, IL-22, TNF-α, and other mediators that act directly on keratinocytes.

    “These populations produce IL-17A, IL-17F, IL-22, TNF-α, and other mediators that act directly on keratinocytes.”

    From The Cutaneous Immune Microenvironment in Selected Inflammatory Skin Diseases: Linking Histopathology, Mechanisms, and Targeted Therapy (2026) · cites this paper as [18]

    Section 2.3 (page unavailable) says Th22 lymphocytes and other immune subsets secrete IL-22, and reports IL-22 production by cultured CTCL cells. It does not establish that the specified populations produce the full list of IL-17A, IL-17F, IL-22 and TNF-α, or that those mediators act directly on keratinocytes; searches for those terms found no supporting passage. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • IL-22 stimulates keratinocyte hyperplasia and abnormal differentiation, contributing to acanthosis, parakeratosis, and loss of the granular layer.

    “IL-22 will stimulate keratinocyte hyperplasia and abnormal differentiation, contributing to acanthosis, parakeratosis, and loss of the granular layer.”

    From The Cutaneous Immune Microenvironment in Selected Inflammatory Skin Diseases: Linking Histopathology, Mechanisms, and Targeted Therapy (2026) · cites this paper as [18]

    Section 2.3 (page unavailable) links IL-22 activation to CCL20 activity and says enhanced CCL20 activity may induce epidermal hyperplasia. It does not state that IL-22 directly stimulates keratinocyte hyperplasia or abnormal differentiation, or describe acanthosis, parakeratosis, or loss of the granular layer. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • TNF-α, IL-17, and IL-22 magnify transcriptional responses in keratinocytes and endothelial cells.

    “TNF-α, IL-17, and IL-22 will magnify transcriptional responses in keratinocytes and endothelial cells.”

    From The Cutaneous Immune Microenvironment in Selected Inflammatory Skin Diseases: Linking Histopathology, Mechanisms, and Targeted Therapy (2026) · cites this paper as [18]

    Section 2.3 (page unavailable) says IL-22 induces CCL20 and STAT3 expression in the context of cutaneous T-cell lymphoma. It does not address whether TNF-α, IL-17, and IL-22 magnify transcriptional responses in keratinocytes or endothelial cells; searches for those cell types and cytokine combinations found no such passage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
