This report involves a 54-year-old female patient diagnosed with diffuse large B-cell lymphoma who developed interstitial pneumonia (IP) during treatment. The patient presented to the ward with enlarged lymph nodes in the neck and was treated with the standard regimen, which included rituximab, cyclophosphamide, doxorubicin liposomes, vincristine, and prednisone (R-CDOP regimen). After 3 cycles, the treatment was assessed as effective. However, following the 4th cycle, the patient experience shortness of breath after physical activity. A repeat lung computer tomography indicated IP, which completely recovered after receiving "full coverage" treatment. Subsequently, the patient underwent 2 cycles of cyclophosphamide, doxorubicin liposomes, vincristine, and prednisone (CDOP), followed by local radiotherapy. Currently, the patient is now being followed up with regular reviews., (© 2023 The Author(s).)

Immune thrombocytopenia (ITP) is common in the elderly. Because of the coexistence of multiple diseases, there are many reservations regarding corticosteroid use in the elderly. Thrombopoietin (TPO) and its analogs can promote platelet production, but it is often difficult to correct TP in a short period. Recombinant human TPO (rh-TPO) acting on the cell membrane and the small-molecule TPO-receptor (MPL) agonist acting on the transmembrane receptor may have synergistic effects and accelerate platelet production because of different sites of action in the signaling pathway. In this study, two elderly patients with refractory ITP were successfully treated with two TPO-MPL signaling pathway agonists: recombinant human thrombopoietin (rh-TPO) and eltrombopag. This combination is safe with rapid and lasting effects. However, in elderly patients with refractory, recurrent, and glucocorticoid contraindications, the combination of different TPO agonists' clinical efficacy and adverse reactions needs to be further evaluated., (© 2022 Published by Elsevier B.V. on behalf of Chinese Medical Association (CMA).)
