Abstract
Cancer is the second leading cause of death globally and its incidence and mortality are rapidly increasing worldwide. The dynamic interaction of immune cells and tumor cells determines the clinical outcome of cancer. Immunotherapy comes to the forefront of cancer treatments, resulting in impressive and durable responses but only in a fraction of patients. Thus, understanding the characteristics and profiles of immune cells in the tumor microenvironment (TME) is a necessary step to move forward in the design of new immunomodulatory strategies that can boost the immune system to fight cancer. Histamine produces a complex and fine-tuned regulation of the phenotype and functions of the different immune cells, participating in multiple regulatory responses of the innate and adaptive immunity. Considering the important actions of histamine-producing immune cells in the TME, in this review we first address the most important immunomodulatory roles of histamine and histamine receptors in the context of cancer development and progression. In addition, this review highlights the current progress and foundational developments in the field of cancer immunotherapy in combination with histamine and pharmacological compounds targeting histamine receptors.

Abstract
BACKGROUND COVID-19 can be related to any diseases caused by microbial infection(s) because 1) co-infection with COVID-19-related virus and other microorganism(s) and 2) because metabolites produced by microorganisms such as bacteria, fungi, and protozoan can be involved in necrotizing pneumonia and other necrotizing medical conditions observed in COVID-19. OBJECTIVE By way of illustration, the microbial metabolite of aromatic amino acid tryptophan, a biogenic amine tryptamine inducing neurodegeneration in cell and animal models, also induces necrosis. METHODS This report includes analysis of COVID-19 positivity by zip codes in Florida and relation of the positivity to population density, possible effect of ecological and social factors on spread of COVID-19, autopsy analysis of COVID-19 cases from around the world, serum metabolomics analysis, and evaluation of autoantigenome related to COVID-19. RESULTS In the present estimations, COVID-19 positivity percent per zip code population varied in Florida from 4.65% to 44.3% (February 2021 data). COVID-19 analysis is partially included in my book Microbial Metabolism and Disease (2021). The autoantigenome related to COVID-19 is characterized by alterations in protein biosynthesis proteins including aminoacyl-tRNA synthetases. Protein biosynthesis alteration is a feature of Alzheimer's disease. Serum metabolomics of COVID-19 positive patients show alteration in shikimate pathway metabolism, which is associated with the presence of Alzheimer's disease-associated human gut bacteria. CONCLUSION Such alterations in microbial metabolism and protein biosynthesis can lead to toxicity and neurodegeneration as described earlier in my book Protein Biosynthesis Interference in Disease (2020).

Abstract
Mast cells are unique tissue-resident immune cells of the myeloid lineage that have long been implicated in the pathogenesis of allergic and autoimmune disorders. More recently, mast cells have been recognized as key orchestrators of anti-tumor immunity, modulators of the cancer stroma, and have also been implicated in cancer cell intrinsic properties. As such, mast cells are an underrecognized but very promising target for cancer immunotherapy. In this review, we discuss the role of mast cells in shaping cancer and its microenvironment, the interaction between mast cells and cancer therapies, and strategies to target mast cells to improve cancer outcomes. Specifically, we address (1) decreasing cell numbers through c-KIT inhibition, (2) modulating mast cell activation and phenotype (through mast cell stabilizers, FcεR1 signaling pathway activators/inhibitors, antibodies targeting inhibitory receptors and ligands, toll like receptor agonists), and (3) altering secreted mast cell mediators and their downstream effects. Finally, we discuss the importance of translational research using patient samples to advance the field of mast cell targeting to optimally improve patient outcomes. As we aim to expand the successes of existing cancer immunotherapies, focused clinical and translational studies targeting mast cells in different cancer contexts are now warranted.

Abstract
Mast cells have historically been studied mainly in the context of allergic disease. In recent years, we have come to understand the critical importance of mast cells in tissue remodeling events and their role as sentinel cells in the induction and development of effective immune responses to infection. Studies of the role of mast cells in tumor immunity are more limited. The pro-tumorigenic role of mast cells has been widely reported. However, mast cell infiltration predicts improved prognosis in some cancers, suggesting that their prognostic value may be dependent on other variables. Such factors may include the nature of local mast cell subsets and the various activation stimuli present within the tumor microenvironment. Experimental models have highlighted the importance of mast cells in orchestrating the anti-tumor events that follow immunotherapies that target innate immunity. Mast cells are long-lived tissue resident cells that are abundant around many solid tumors and are radiation resistant making them unique candidates for combined treatment modalities. This review will examine some of the key roles of mast cells in tumor immunity, with a focus on potential immunotherapeutic interventions that harness the sentinel role of mast cells.

Abstract
Histamine dihydrochloride is a vasoactive biogenic amine. It inhibits the reactive oxygen species formation in monocytes via histamine H2 receptors and protects natural killer and T cells from oxidative damage. Histamine has the potential to optimize cytokine-induced activation of T cells and natural killer cells; therefore, the addition of histamine to cytokine treatment may improve treatment efficacy. Clinical trials in solid tumors and in acute myeloid leukemia have demonstrated the potential to improve treatment outcome when histamine dihydrochloride is combined with immunotherapy. In patients with metastatic malignant melanoma, this strategy improved remission rates and increased survival. On the other hand, less promising results were reported for histamine dihydrochloride added to cytokines in patients with other solid tumors, especially in advanced renal cell carcinoma. A recent international Phase III trial performed in 320 patients showed that maintenance therapy with histamine dihydrochloride and IL-2 was able to improve leukemia-free survival in patients with acute myeloid leukemia, without an effect on overall survival. The combination of histamine dihydrochloride with IL-2 potentially offers an efficacious and tolerable maintenance strategy for patients with acute myeloid leukemia; however, its impact on survival remains to be explored.

Abstract
Histamine modulates an immunological response through stimulation of appropriate receptor--H1R proinflammatory or H2R suppressive. The participation of histamine in regulation of an immunological response in the course of neoplastic disease is determined by the expression of particular receptor. The aim of our work was the investigation of the expression of mRNA of two types of histamine receptors in peripheral blood lymphocytes and the evaluation of skin-prick test with histamine in lung cancer patients before and after surgery. The investigation was performed on 15 patients qualified to surgery before and 7-10 days after treatment and on 12 healthy subjects. Reverse transcriptase polymerase chain reaction (RT-PCR) with primers labeled with fluorescent dyes was performed. Intensity of fluorescence was expressed as relative fluorescence units (RFU). The data were analysed using ABI Prism 310 GeneScan collection software Version 3.1. Skin-prick test with histamine was evaluated after 10 min by measuring the diameter of the weal. The expression of H1R and H2R mRNA in healthy subjects was not significantly different in contrast to the lung cancer patients in which a significant prevalence of H2R mRNA expression was observed before surgery and only slightly decreased after (P < 0.001). Skin-prick test--negative in one patient before surgery, after treatment was positive in all patients and the diameter of histamine weal was significantly increased (P < 0.001). One may assume that the prevalence of the expression of H2R mRNA in patients reflects the status of immunosuppression caused by cancer. Since histamine exerts its suppressive activity trough H2R it seems reasonably to include the antagonists of this receptor to the cancer therapy which may restore a relative balance between accessibility of both types of histamine receptors.

Abstract
Interleukin-2 (IL-2) is used to treat metastatic renal cell carcinoma and malignant melanoma, but its use is limited by the severe hypotension it produces. We have shown here that M40403, a superoxide dismutase (SOD) mimetic, blocked IL-2-induced hypotension and allowed the dose of IL-2 to be increased in mice. The reversal of IL-2-mediated hypotension was associated with an increase in plasma catecholamines. In addition, M40403 increased lymphokine-activated killer (LAK) cell cytotoxicity in vitro and in vivo, through inhibition of macrophage superoxide production. Treatment of methylcholanthrene-induced (Meth A) ascites tumors with IL-2 and > or =3 mg per kg body weight M40403 induced 50% complete remissions lasting for more than 200 d, which was longer than those of untreated mice (15-d median survival) or mice treated with IL-2 alone (22-d median). Growth of subcutaneous implants of RENCA renal carcinoma was also inhibited by the combination of IL-2 and M40403. These results established that M40403 prevented IL-2 from causing dose-limiting hypotension, while enhancing its anticancer activity.

Abstract
Melanoma cells constitutively produce various cytokines as well as growth factors and express their corresponding receptors. Exogenous histamine is known to be a growth factor for some tumours while in other cases histamine inhibits tumour growth, and acts on G protein-coupled H1 and H2 histamine receptors. In previous studies we have detected the expression of the l-histidine decarboxylase (HDC) gene and the presence of HDC protein in human melanoma cell lines. In the present study, the activities of the histamine-forming enzyme HDC and of the degrading enzymes diamine oxidase (DAO) and histamine N-methyltransferase (HNMT) were measured in primary (WM35 and WM983) and metastatic (M1 and HT168) human melanoma cell lines. HDC activity was found in WM35 and WM983 cell lines, while detectable HNMT activity was measured in WM983, M1 and HT168 lines. In contrast, DAO showed very low activity in melanoma cell lines. Melanoma cells release a detectable amount of histamine into the medium without external stimuli. These findings support the possibility of autonomous histamine metabolism in melanoma cells. Our results suggest that not only exogenous histamine but also histamine produced and released by the melanoma cells and acting as an autocrine and paracrine factor may influence cell proliferation and modulate the in situ immune response of the host.

Abstract
Intravenous high dose bolus therapy with interleukin-2 (IL2) is associated with low overall response rates (15%) and significant toxicity. Phase II and III trials of a lower dose subcutaneous regimen of IL2 administered alone (n = 152) or in combination with histamine dihydrochloride (n = 239) have recently been completed. This article describes a comprehensive safety and toxicity analysis of the results of these two trials. The phase III trial demonstrated a survival benefit in patients with liver metastases in the histamine/IL2 arm. Eligible patients had stage IV malignant melanoma with at least one measurable lesion. Toxicity was graded using the National Cancer Institute (NCI) common toxicity scale. All reported adverse events were included in the analysis. Almost all toxicities in each treatment group were NCI grade 1 or 2. The incidence of toxicities expected to occur with histamine treatment, such as hypotension/vasodilation, headache and injection site reaction, were higher among patients receiving histamine. With the exception of headache, the incidence of grade 3 or 4 toxicities was similar across the treatment groups. The addition of histamine to the subcutaneous IL2 regimen did not result in a difference in the incidence of drug interruption, dose modification or discontinuation. Study-related deaths were low and were not impacted by the addition of histamine to the IL2 regimen.

Abstract
The aim of the present work is to investigate whether histamine assay could be useful in detecting the presence of primary cancer. The high-performance liquid chromatographic (HPLC)-based o-phthalaldialdehyde (OPA) histamine derivatization assay was investigated with respect to several variables, dramatization reagent concentration, organic solvent requirement, derivatization time and counter-ion effect on chromatographic separation. The OPA histamine assay, in the absence of added -SH groups, was found to detect histamine in whole blood samples with relative standard deviations <14% and recoveries not less than 90%. The assay showed high selectivity towards other aminic-containing compounds and a detection limit of 18 nM of histamine was evaluated. Calibration curves in the range 50-500 nM were obtained by using histamine standards in 0.1 M HCl with a regression coefficient value (r(2)) of 0.9969. In order to assess the usefulness of this assay in primary tumor monitoring, two groups of individuals, 29 controls and 29 colon cancer patients were selected, and serum levels of histamine, carcinogen embrionary antigen (CEA), carcinogen antigen 19.9 (CA19.9), and tumor staging, were determined. A significant histamine reduction (P=0.028) between controls (180.12+/-70.4 nM) and patients (134.5+/-90.3 nM) was found, and a cut-off value of 157.5 nM was extrapolated as intercept point of sensitivity and specificity curves. Fifty percent of patients showed a histamine value below the cut-off, while 45.8 and 8.3% of patients were positive for CEA and CA19.9, respectively. No correlation was found between Tumor Node Metastasis staging and histamine amount, indicating that this marker is not related to the tumor mass. Our data suggest that histamine level, together with other classical tumor markers, could be a potentially interesting tumor marker in colon cancer monitoring.

Abstract
Recent clinical trials in melanoma and leukemia have demonstrated potential for increased survival time and improved remission when histamine dihydrochloride is added to cytokine monotherapy. In the present study, the pharmacokinetics of subcutaneous histamine (1 mg) in 21 healthy subjects and 12 melanoma patients was determined via model-dependent methods. Drug-drug interactions with subcutaneous interleukin-2 (1.1 mg) were evaluated in a combined cohort of patients with melanoma (n = 8) or renal cell carcinoma (n = 4). Histamine dihydrochloride administered over 10 minutes in healthy subjects peaked at 18 minutes (Cmax 38 nmol/L), attained a distribution volume of 59 L, and was eliminated at 6%/min. The results were similar in a 20-minute infusion in melanoma patients. No gender effects were observed (p > 0.05). Interleukin-2 injected either 10 minutes prior to or 10 minutes following histamine dihydrochloride had no effect on histamine kinetics. Histamine dihydrochloride administered 10 minutes prior to injection of interleukin-2 also had no effect on interleukin-2 kinetics. Maximal concentration of interleukin-2 (2,442 pg/ml) occurred at 2.5 hours with an elimination half-life of 1.7 hours, area under the curve (AUC) of 15,746 pg x h/ml, and volume of distribution and plasma clearance of 194 L and 74 L/h, respectively. However, interleukin-2 Cmax (1,758 pg/ml) and AUC (12,448 pg x h/ml) were reduced when histamine dihydrochloride was infused 10 minutes following interleukin-2, likely due to the pharmacodynamic effects of histamine, including increased heart rate and reduced blood pressure. It is concluded that histamine dihydrochloride and interleukin-2 can be safely coadministered with minimal interaction.

Abstract
Approximately 31,000 new cases of renal cell carcinoma (RCC) are diagnosed in the United States each year and 30% to 40% of these will eventually become metastatic disease. The primary tumor often grows to considerable size before symptoms are apparent, which could explain the high rate of metastatic RCC (mRCC). The median survival of mRCC after diagnosis is 8 to 12 months and the 5-year survival is less than ideal. Traditionally, surgery has been the treatment of choice for mRCC. Chemotherapeutic agents tested so far have been disappointing, perhaps because of a high expression of the multidrug resistance gene or the high content of glutathione in RCC cells. However, the spontaneous regression of mRCC in some cases suggests that these tumor cells are responsive to immunologic mechanisms. Initial interest has focused on two cytokines, interferon-alpha (IFN-alpha) and interleukin-2 (IL-2), with response rates ranging from 15% to 20%. Both IL-2 and IFN-alpha are pleiotropic compounds with specific effects on many leukocyte subsets, in addition to directly affecting tumor proliferation, angiogenesis, and antigen expression. The mechanisms by which these immunoenhancing cytokines exert antitumor effects are still unknown. However, many agree that activation of T cells and natural killer cells is a pivotal part of the antitumor efficacy. For example, some investigators have found that pretreatment levels of natural killer cells and T cells predict a response to IL-2 and IFN-alpha in mRCC. Others report a relationship between activation of peripheral blood lymphocytes and response to cytokine therapy. Expansion of activated T cells in blood during treatment with these two cytokines seems to relate to clinical efficacy in patients with RCC.

Abstract
Interleukin-2 and interferon-alpha have been used as therapeutic options in the treatment of certain malignancies such as metastatic malignant melanoma, acute myelogenous leukemia, and renal cell carcinoma. However, the outcome with these agents has been less than optimal. While experiments in vitro would lead one to believe that these agents would be useful therapeutic alternatives, the situation in vivo is confounded by the fact that the microenvironments of the tumor and surrounding tissue are infiltrated with monocytes and macrophages, which suppress the cytotoxic activity of T cells and natural killer cells. The mechanism by which this occurs is through the generation of reactive oxygen species that are responsible for apoptosis by both T cells and natural killer cells. Histamine abrogates this suppression, thus restoring the cytotoxicity of these cells. Therefore, the addition of histamine to regimens containing cytokines is expected to optimize cytokine therapy. Clinical trials with these regimens are under way in the treatment of metastatic malignant melanoma, acute myelogenous leukemia, and renal cell carcinoma. Results published thus far indicate that the addition of histamine to cytokine therapy is both safe and efficacious in the treatment of these diseases.

Abstract
PURPOSE Reactive oxidative species (ROS) produced by phagocytic cells have been ascribed a role in the localized suppression of lymphocyte function within malignant tumors. Histamine has been shown to inhibit ROS formation and possibly synergize with cytokines to permit activation of natural killer cells and T cells. This study was designed to determine whether the addition of histamine to a subcutaneous (SC) regimen of interleukin-2 (IL-2) would improve the survival of metastatic melanoma patients. PATIENTS AND METHODS A phase III, multicenter, randomized, parallel group study comparing IL-2 plus histamine with IL-2 alone was conducted in 305 patients with advanced metastatic melanoma. Patients were randomized to IL-2 (9 MIU/m(2) bid SC on days 1 to 2 of weeks 1 and 3, and 2 MIU/m(2) bid SC on days 1 to 5 of weeks 2 and 4) with or without histamine (1.0 mg bid SC days 1 to 5, weeks 1 to 4). The primary end point, survival, was prospectively applied to all randomized patients (intent-to-treat-overall population, ITT-OA) and all patients having liver metastases at randomization (ITT-LM population). Secondary end points included safety of the combined treatment, time to disease progression, and response rate. RESULTS Combined treatment with histamine plus IL-2 significantly improved overall survival in the ITT-LM population (P =.004) and showed a trend for improved survival in the ITT population (P =.125). Grade 3 and 4 adverse events were comparable in the two arms. CONCLUSION Use of histamine as an adjunct to IL-2 is safe, well tolerated, and associated with a statistically significant prolongation of survival compared with IL-2 alone in metastatic melanoma patients with liver involvement. Further trials to confirm and understand the role of histamine in this combination treatment are underway.

Abstract
Interleukin-2 is a remarkable activator of lymphocytes with anti-neoplastic properties such as T-cells or natural killer cells, but tumor regression only rarely occurs in interleukin-2-treated cancer patients. In this review, we focus on interactions between monocytes/macrophages and T-cells/natural killer-cells, and in particular the role of such interactions for the outcome of cancer immunotherapy with interleukin-2. We propose that interleukin-2 therapy should be supplemented with compounds that alleviate toxicity inflicted by monocyte/macrophage-derived reactive oxygen metabolites within and around tumors. The hypothesis is founded on data demonstrating that (i) functions of intratumoral lymphocytes in many human malignant tumors are inhibited by reactive oxygen metabolites, generated by neighboring monocytes/macrophages, (ii) interleukin-2 only weakly activates T-cells or natural killer cells in an environment of oxidative stress, and (iii) inhibitors of the formation of reactive oxygen metabolites or scavengers of reactive oxygen metabolites synergize with interleukin-2 to activate these lymphocyte subsets. We also review the preclinical background to the use of histamine dihydrochloride, an inhibitor of reactive oxygen metabolite formation in monocytes/macrophages, as a supplement to cancer immunotherapy with interleukin-2.

Abstract
The functions of intratumoral lymphocytes in many human malignant tumors are inhibited by reactive oxygen species (ROS), generated by adjacent monocytes/macrophages (MO). In vitro data suggest that immunotherapeutic cytokines such as interleukin-2 (IL-2) or interferon-alpha (IFN-alpha) only weakly activate T cells or natural killer (NK) cells in a reconstituted environment of oxidative stress and that inhibitors of the formation of ROS or scavengers of ROS synergize with IL-2 and IFN-alpha to activate T cells and NK cells. In this review, we focus on the immunoenhancing properties of histamine, a biogenic amine. Histamine inhibits ROS formation in MO via H2-receptors; thereby, histamine protects NK cells from MO-mediated inhibition and synergizes with IL-2 and IFN-alpha to induce killing of NK cell-sensitive human tumor cells in vitro. Histamine also optimizes cytokine-induced activation of several subsets of T cells by affording protection against MO-inflicted oxidative inhibition. The putative clinical benefit of histamine as an adjunct to immunotherapy with IL-2 and/or IFN-alpha is currently evaluated in clinical trials in metastatic malignant melanoma and acute myelogenous leukemia.

Abstract
The survival of patients with cancer has improved steadily but incrementally over the last century, with the advent of effective anticancer treatments such as chemotherapy and radiotherapy. However, the majority of patients with metastatic disease will not be cured by these measures and will eventually die of their disease. New and more effective methods of treating these patients are required urgently. The immune system is a potent force for rejecting transplanted organs or microbial pathogens, but effective spontaneous immunologically induced cancer remissions are very rare. In recent years, much has been discovered about the mechanisms by which the immune system recognizes and responds to cancers. The specific antigens involved have now been defined in many cases. Improved adjuvants are available. Means by which cancer cells overcome immunological attack can be exploited and overcome. Most importantly, the immunological control mechanisms responsible for initiating and maintaining an effective immune response are now much better understood. It is now possible to manipulate immunological effector cells or antigen-presenting cells ex vivo in order to induce an effective antitumour response. At the same time, it is possible to recruit other aspects of the immune system, both specific (e.g. antibody responses) and innate (natural killer cells and granulocytes).

Abstract
Interleukin-2 (IL-2) is an effective activator of lymphocytes with anti-neoplastic properties such as T-cells or natural killer cells, and this property of IL-2 has formed the basis for its widespread used as an immunotherapeutic agent in human neoplastic disease. In recent years, IL-2 therapy for solid neoplastic diseases and hematopoietic cancers has been supplemented with histamine dihydrochloride with the aim of counteracting immunosuppressive signals from monocytes/macrophages. Here we review the preclinical basis for the use of histamine as an adjunct to IL-2 in cancer immunotherapy.

Abstract
The ether phospholipid AMG-PC (1-O-hexadecyl-2-O-methyl-rac-glycero-3-phosphocholine, ET-16-OCH3) affects rat mast cell responses in a dual manner. A powerful synergistic interaction with the ionophore A23187 and the phorbol ester TPA indicated an involvement of mechanisms relating to activation of protein kinase C. In contrast, the related hexadecylphosphocholine (miltefosine) only causes inhibition. Here, the investigation is extended to include the antineoplastic ether phospholipids ET-18-OCH3 (edelfosine) and BM 41.440 (ilmofosine) as well as the heterocyclic hexadecylphosphocholine analogues D-20133 and D-21266. The four test drugs had an influence very similar to that of AMG-PC on mast cell responses to selected secretagogues, i.e., they both enhanced and inhibited antigen-induced histamine release whereas only inhibition was observed with compound 48/80. They significantly amplified the response to A23187 alone as well as in combination with TPA and, under certain conditions, inhibitory effects were observed with ET-18-OCH3, D-20133 and D-21266 but not with BM 41.440. The latter was more effective in enhancing A23187 mediated responses and had a wider concentration range of activity than the other three drugs. D-20133 and D-21266 influenced mast cells in a manner distinct from that of hexadecylphosphocholine and may share cellular targets with the ether phospholipids. The results raise speculation of an involvement of mast cells in the immunomodulatory action of these drugs.

Abstract
Over the last decade, there has been a considerable increase in understanding of immune responses against cancers, the antigenic structures on tumor cells recognised by the immune system, and the development of more effective vaccines. There is, however, very limited understanding of why the immune system most often fails to control tumor growth and progression. In some patients, it is difficult to demonstrate immune responses to their tumors, and it may be assumed that this reflects poor recognition of tumor antigens, induction of anergy in lymphocytes, or suppression of immune responses by tumor-derived factors. In other patients, tumor progression appears to occur despite the presence of antibody or cell-mediated responses. This may indicate selection of tumor cells that have lost tumor antigens or HLA antigens by immune responses against the tumor. Tumor cells may also become resistant to mediators of apoptosis, such as Fas ligand and tumor necrosis factor-related apoptosis-inducing ligand used by lymphocytes to kill tumor cells. It is suggested that development of effective immunotherapy will need to include strategies that take into account these limitations of immune responses and classification of tumors according to the treatment approach most likely to succeed.

Abstract
Interleukin-2 (IL-2) and interferon-alpha (IFN-alpha) are potent activators of natural killer (NK) cells and other anti-tumor effector cells, but the results obtained in clinical trials with these cytokines have proved disappointing in many forms of cancer. It may be that IL-2 and IFN-alpha are often not sufficiently effective because intratumoral monocytes/macrophages (MO) inhibit the cytokine-induced activation of cytotoxic effector lymphocytes such as NK-cells at the site of tumor growth. An essential part of this inhibitory signal is conveyed by MO-derived reactive oxygen species (ROS), which potently inhibit NK-cell-related functions, including the constitutive and cytokine-induced cytotoxicity against tumor cells. Histamine, a biogenic amine, inhibits ROS formation in MO; thereby, histamine synergizes with IL-2 and with IFN-alpha to induce killing of NK-cell-sensitive human tumor cells in vitro. Furthermore, treatment of tumor-bearing mice with histamine potentiates cytokine-induced killing of NK-cell-sensitive murine tumor cells in vivo. In ongoing clinical trials, histamine has been added to IL-2 or IFN-alpha in immunotherapy of human neoplastic disease. The results of two pilot trials in metastatic melanoma suggest that the addition of histamine to IL-2/IFN-alpha prolongs survival time and induces regression of tumors, such as liver melanoma, which are considered refractory to immunotherapy with IL-2 or IFN-alpha. In acute myelogenous leukemia (AML), histamine and IL-2 have been given in order to protect patients in remission against relapse of leukemic disease. The potential benefit of histamine therapy in melanoma and AML will be evaluated in randomized trials.
