Pendahulan: Imunoterapi untuk kanker digunakan berdasarkan prinsip penyakitnya bahwa sistem kekebalan tubuh mampu menghasilkan respons imun terhadap sel-sel tumor. Saat ini tatalaksana yang tersedia untuk pasien melanoma selektif berdasarkan tingkat respons dari penyakitnya. Tujuan: Untuk mengetahui tatalaksana melanoma yang menggunakan imunologi. Metode: Artikel ini disusun menggunakan metode literature review, menggunakan 32 sumber berasal dari jurnal dan buku. Hasil: Interferon-α telah disetujui untuk pengobatan ajuvan stadium III melanoma dengan peningkatan survival rate. Diperlukan pendekatan baru dan lebih inovatif dengan peningkatan efek terapi. Prognosis pasien dengan melanoma metastasis di dunia telah berubah secara dramatis sejak adanya imun checkpoint inhibitor. Pembahasan: Ipilimumab, yang menargetkan protein cytotoxic T lymphocyte-associated protein 4 (CTLA-4) adalah agen pertama yang ada. Selanjutnya nivolumab dan pembrolizumab yang berikatan dengan protein programmed death protein 1 (PD-1) telah terbukti lebih efektif dan lebih rendah angka toksisitasnya daripada ipilimumab. Kombinasi nivolumab atau pembrolizumab dengan ipilimumab telah menghasilkan peningkatan tingkat respons dan hasil survival rate pasien. Tinjauan pustaka ini akan mengeksplorasi data uji klinis penting yang telah menyebabkan penggunaan agen imunoterapi ini di dunia dan beberapa hasil uji klinis yang saat ini dilaporkan untuk terapi kombinasi baru. Simpulan: Saat ini terapi imunologi untuk tatalaksana melanoma dapat di terapkan.   Kata kunci: Imunoterapi, kemoterapi, melanoma, tatalaksana

Immune checkpoint inhibitors (ICIs) targeting cytotoxic T-lymphocyte associated protein-4 (CTLA-4), programmed cell death protein-1 (PD-1), and its ligand PD-L1 are established cancer immunotherapies for solid tumor and hematologic malignancies. These therapies are involved in immune-related adverse events (irAE), both general and rheumatic ones. In general, immune-related adverse events (irAE) management includes drug-holding, tapering doses of corticosteroids, and specific immunosuppression for clinically severe cases, such as infliximab or mycophenolate.

ABSTRACT Chronic helminth infections are known to be associated with the modulation of antigen-specific T-cell responses. Strongyloides stercoralis infection is characterized by the downmodulation of antigen-specific Th1 and Th17 responses and the upregulation of Th2 and Th9 responses. Immune homeostasis is partially maintained by negative regulators of T-cell activation, cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1), which dampen effector responses during chronic infections. However, their roles in S. stercoralis infection are yet to be defined. Therefore, we sought to determine the role of CTLA-4 and PD-1 in regulating CD4+ and CD8+ T-cell responses and examined the frequencies of monofunctional and dual functional Th1/T cytotoxic type 1 (Tc1), Th17/Tc17, Th2/Tc2, and Th9/Tc9 cells in S. stercoralis infection in 15 infected individuals stimulated with parasite antigen following CTLA-4 or PD-1 blockade. Our data reveal that CTLA-4 or PD-1 blockade results in significantly enhanced frequencies of monofunctional and dual functional Th1/Tc1 and Th17/Tc17 cells and, in contrast, diminishes the frequencies of monofunctional and dual functional Th2/Tc2 and Th9/Tc9 cells with parasite antigen stimulation in whole-blood cultures. Thus, we demonstrate that CTLA-4 and PD-1 limit the induction of particular T-cell subsets in S. stercoralis infection, which suggests the importance of CTLA-4 and PD-1 in immune modulation in a chronic helminth infection.

PURPOSE The risk of immune checkpoint inhibitor therapy–related GI adverse events in patients with cancer and inflammatory bowel disease (IBD) has not been well described. We characterized GI adverse events in patients with underlying IBD who received immune checkpoint inhibitors. PATIENTS AND METHODS We performed a multicenter, retrospective study of patients with documented IBD who received immune checkpoint inhibitor therapy between January 2010 and February 2019. Backward selection and multivariate logistic regression were conducted to assess risk of GI adverse events. RESULTS Of the 102 included patients, 17 received therapy targeting cytotoxic T-lymphocyte antigen-4, and 85 received monotherapy targeting programmed cell death 1 or its ligand. Half of the patients had Crohn’s disease, and half had ulcerative colitis. The median time from last active IBD episode to immunotherapy initiation was 5 years (interquartile range, 3-12 years). Forty-three patients were not receiving treatment of IBD. GI adverse events occurred in 42 patients (41%) after a median of 62 days (interquartile range, 33-123 days), a rate higher than that among similar patients without underlying IBD who were treated at centers participating in the study (11%; P < .001). GI events among patients with IBD included grade 3 or 4 diarrhea in 21 patients (21%). Four patients experienced colonic perforation, 2 of whom required surgery. No GI adverse event–related deaths were recorded. Anti–cytotoxic T-lymphocyte antigen-4 therapy was associated with increased risk of GI adverse events on univariable but not multivariable analysis (odds ratio, 3.19; 95% CI, 1.8 to 9.48; P = .037; and odds ratio, 4.72; 95% CI, 0.95 to 23.53; P = .058, respectively). CONCLUSION Preexisting IBD increases the risk of severe GI adverse events in patients treated with immune checkpoint inhibitors.

Background: Immune checkpoint blockade therapies including cytotoxic-T-lymphocyte antigen 4 (CTLA-4) and programmed cell death protein-1 (PD-1) inhibitors have become indispensable tools for treating melanoma and other cancers. An increasing number of diverse cutaneous adverse reactions to immunotherapy have been documented in the literature and have been reported to affect up to 40% of patients treated with targeted therapies. Method & results: Herein, we report a case of a patient with metastatic melanoma treated with checkpoint inhibitor therapy who developed vitiligo, gastritis and hepatitis, all identified as adverse immune events and attributable to his immunotherapy regimen. He subsequently developed acquired idiopathic generalized hypohidrosis with biopsy of lesional skin demonstrating a peri-eccrine lymphocytic infiltrate. Conclusion: These findings suggest this acquired generalized hypohidrosis represents a lymphocyte-mediated adverse immune event related to this patient’s checkpoint inhibitor therapy.

Immune checkpoint inhibitors (ICIs), including cytotoxic T-lymphocyte associated antigen 4 (CTLA-4) and programmed death protein 1 (PD-1) or its ligand (PD-L1), are a new generation of immuno-oncological drugs that to date have demonstrated efficacy in a number of malignancies. The mechanism of ICT inhibitors action consist in the potentiation of the immune response by eliminating the tumor cells inhibitory effect on the T-lymphocytes activation. However, excessive immune system activation can cause the development of a special class of immune-related adverse events (irAEs) involved a wide variety of organs and systems, including the kidneys. Despite the fact that immuno-mediated kidney injury caused by ICI therapy develops quite rarely, it can be serious and determine the patient's prognosis, which necessitates early diagnosis and timely start of treatment. In this regard, awareness of the manifestations of ICI-associated renal irAEs is particularly relevant not only for oncologists and for nephrologists, but for doctors of other specialties. In this review, we elucidated the main variants of immuno-mediated kidney injury caused by ICI therapy, discussed possible predictors and mechanisms of their development, and considers the general principles of diagnosis and management of patients according to the severity of irAEs.
