(1) Background: The epidermal growth factor inhibitors (EGFRIs)/tyrosine kinase inhibitors (TKIs) are effective for cancer target therapy, but acneiform rashes or so-called inflammatory papulopustular exanthemas are common (50% to 90%). The conventional therapy for EGFRIs/TKIs-induced skin toxicity is steroids and antibacterial drugs, but it is still ineffective for some patients, and EGFRIs/TKIs dose reduction/interruption may be needed. In this study, a modified Chinese herbal medicine, Huang-Lian-Jie-Du decoction cream with Yin-Cold (YC) medicine characteristic, was investigated for the effect on patients suffering EGFRIs/TKIs-induced skin toxicity. (2) Methods: The modified Huang-Lian-Jie-Du (mHLJD) decoction cream was made from 10 herbal medicines, including 4 major medicines (Huanglian, Huangqin, Huangbo, and Zhizi) in traditional HLJD decoction. Patients with EGFRIs/TKIs-induced skin toxicity were enrolled. Patients were excluded if they also used other cream for skin toxicity. Skin conditions were monitored by follow up every 2 weeks. The patients’ characteristics, the skin toxicities, treatment response, and adverse events were recorded and analyzed until skin problems resolved or the study ended. (3) Results: The mHLJD decoction cream and its sub-packages were stored at 4 °C before use. Thirty-four patients who had grade 1–3 skin toxicities after receiving EGFRIs/TKIs were enrolled. Seven patients withdrew or were excluded. Finally, data from 27 patients were analyzed. The mean grade of rash acneiform was significantly decreased from 2.19 (ranged 1 to 3) to 0.88 (ranged 0 to 2) after mHLJD decoction cream treatment for 4 weeks and to 0.55 (ranged 0 to 2) after mHLJD decoction cream treatment for 8 weeks. Additionally, the mean grade of dry skin was also significantly decreased from 1.57 (ranged 1 to 2) to 0.71 (ranged 0 to 1) after mHLJD decoction cream treatment for 4 weeks. The changes of skin toxicity were significant, with no obvious adverse events. (4) Conclusions: In summary, the mHLJD decoction cream provides benefits for alleviation of EGFRIs/TKIs-induced skin rash acneiform and dry skin. Additionally, no obvious side effects were found in patients using mHLJD decoction cream.

Dry skin is a symptom of skin barrier dysfunction that evokes pruritus; however, the cutaneous neuroimmune interactions underlying dry skin-induced pruritus remain unclear. Therefore, we aimed to elucidate the mechanisms underlying dry skin-induced pruritus. To this end, an acetone/ethanol/water (AEW)-induced mouse model of dry skin was used in this study. We observed that the production of thymic stromal lymphopoietin (TSLP) significantly increased in the keratinocytes of AEW mice. Importantly, treatment with an antagonist of transient receptor potential cation channel subfamily V member 4 (TRPV4), HC067047, ameliorated dry skin conditions in AEW mice. The symptoms of dry skin were significantly reduced in Trpv4 knockout (KO) mice following treatment with AEW. The increase in the intracellular calcium levels by TSLP in the dorsal root ganglia (DRG) of Trpv4 KO mice was also significantly attenuated. The spontaneous scratching bouts were significantly decreased in both the HC067047-treated and Trpv4 KO AEW mice. Importantly, the TSLP-dependent release of tryptase from the mast cells was significantly reduced in both the HC067047-treated mice and Trpv4 KO AEW mice. Notably, inhibition of the TSLP-induced signaling pathway in DRG selectively reduced the spontaneous scratching bouts in AEW mice. Overall, the results demonstrated that the cutaneous neuroimmune interactions of TSLP and TRPV4 play pivotal roles in dry skin-induced pruritus.
