A large body of clinical experience on the adverse consequences of cytokine administration has accumulated since the last decade. Side-effects reported after the therapeutic use of cytokines has provided evidence that activation of the immune response may sometimes have deleterious consequences. Several effects appeared as a direct consequence of the immune activation induced by cytokines, e.g. flu-like reactions, vascular leak syndrome. Cytokine-induced exacerbation of underlying diseases or immune dysregulation were other complications of growing concern. Interferon-alpha (IFN-alpha) treatment has now been clearly linked with the exacerbation or the occurrence of several types of autoantibodies or autoimmune diseases (thyroiditis, systemic lupus erythematosus, hematologic disorders, insulin-dependent diabetes mellitus) or diseases involving altered cell-mediated immune functions (inflammatory dermatologic diseases, nephritis, pneumonitis, colitis). By contrast immunological side-effects of IFN-beta and IFN-gamma have been seldom reported. However, the extent of clinical experience with both of these cytokines is still very limited. Interleukin-2 (IL-2) has also been implicated in various conditions that may involve immunopathological processes (thyroid disorders, rheumatoid arthritis, dermatological diseases, interstitial nephritis). Growth factors have been more specifically linked with the development or the exacerbation of dermatological inflammatory diseases through neutrophils, monocytes/macrophages or eosinophils activation (e.g. cutaneous
vasculitis
and generalized cutaneous eruption, Sweet's syndrome, bullous eruption, psoriasis). Exacerbation of autoimmune thyroiditis was described with
granulocyte-macrophage colony-stimulating factor
(
GM-CSF
) only. The immunogenicity of cytokines is also of great relevance and the occurrence of antibodies binding IFN-alpha and IFN-beta, IL2 and
GM-CSF
have been reported. While the clinical significance of non-neutralizing antibodies is not clearly established, an absence of response or reversal of clinical efficacy has been described in patients developing neutralizing antibodies. Finally, several isolated reports have recently suggested that IFN-alpha treatment may be associated with several immunosuppressive effects while IL-2 is clinically associated with an increased incidence of infectious complications.

Human T-cell lymphotropic virus type I (HTLV-I) is known to cause adult T-cell leukemia/T-cell lymphoma and tropical spastic paraparesis/HTLV-I-associated myelopathy. Recent seroepidemiologic, clinical, and virologic studies indicate that the virus is also related to a certain type of uveitis, which has been classified as uveitis without defined etiologies or idiopathic uveitis. According to the seroepidemiologic survey, the seroprevalence of HTLV-I in patients with idiopathic uveitis was significantly higher than that of two control groups, that is, patients with uveitis with defined etiologies and patients with nonuveitic ocular diseases. Clinically, the uveitis seen in HTLV-I carriers is characterized by moderate to severe cellular infiltration in the eye and by moderate retinal
vasculitis
, and the intraocular inflammation responds well to corticosteroid therapy. Interestingly, 25% of female patients with the disease had a previous history of Graves disease with hyperthyroidisms. The following virologic, molecular biologic findings suggest that cytokines produced by HTLV-I-infected T cells in the eye play the central role in the pathogenic mechanisms of the uveitis: (a) the virus load in the peripheral blood monocytes analyzed by the quantitative polymerase chain reaction methods was significantly greater in patients with the uveitis than in asymptomatic carriers, (b) the proviral DNA of HTLV-I and the gene expression of the virus at the mRNA level was detected in the infiltrating cells from the eyes of the patients, (c) the virus particles were detected by electron-microscopic examination in the T-cell clones established from the intraocular fluid of the patients, and (d) the HTLV-I-infected T cells produced a variety of cytokines without any stimuli, such as interleukin (IL)-1 alpha, IL-2, IL-3, IL-6, IL-8, IL-10, tumor necrosis factor alpha, interferon-gamma, and
granulocyte-macrophage colony-stimulating factor
. Based on the seroepidemiologic, clinical, and virologic data, the uveitis seen in HTLV-I carriers is considered to be a distinct clinical entity related to HTLV-I infection, and the disease is designated as HTLV-I uveitis.

Chronic neutropenia associated with collagen vascular disease is seen principally with Felty's syndrome complicating rheumatoid arthritis. Multiple recent reports document the efficacy of both
granulocyte-macrophage colony-stimulating factor
(
GM-CSF
) and granulocyte colony-stimulating factor (G-CSF) in reversing the neutropenia and decreasing the risk of infections in Felty's syndrome. Long-term use of G-CSF appears well tolerated and effective in Felty's syndrome. Of concern, however, have been flares of arthritis and development of leukocytoclastic
vasculitis
in several patients following the use of colony-stimulating factors (CSFs) in Felty's syndrome. The incidence of these complications of CSF therapy appears to be greater in Felty's syndrome than in other disorders. Future studies will need to address the incidence of these side effects, evaluate strategies to reduce risks, and clarify the optimum use of CFSs in Felty's syndrome.

Newer agents of particular interest to rheumatologists are increasingly associated with
vasculitis
. There is now good evidence that treatment with hematopoietic growth factors, including granulocyte colony-stimulating factor and
granulocyte-macrophage colony-stimulating factor
, can cause or mimic vasculitides such as Sweet's syndrome and pyoderma gangrenosum. Similarly, there is strong evidence that clinical use of interferons is associated with a variety of autoimmune phenomenon rarely including
vasculitis
. The increased availability of testing for antineutrophil cytoplasmic antibody (ANCA) has widened the clinical spectrum of systemic vasculitides. There are now many reports that treatment with either hydralazine or propylthiouracil is associated with ANCA-positive
vasculitis
. A small number of case reports also implicate penicillamine and minocycline as agents capable of inducing an ANCA-associated
vasculitis
. Clinicians should be aware of the potential of certain drugs to cause
vasculitis
and especially cautious in using these agents in patients with known
vasculitis
.

Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic growth factor (HGF) with many applications in cancer therapy. The most important applications are reduction in the incidence of febrile neutropenia, acceleration of neutrophil recovery after chemotherapy or bone marrow transplantation, and mobilization of progenitor cells. Many cutaneous adverse reactions associated with HGF have been reported in recent years, including injection site reactions, pyoderma gangrenosum, Sweet's syndrome, cutaneous leucocytoclastic
vasculitis
, and widespread folliculitis. The presence of large histiocytes on the dermis between collagen bundles has been proposed as a characteristic histopathologic finding in cutaneous eruptions secondary to granulocyte colony-stimulating factor and
granulocyte-macrophage colony-stimulating factor
. We report on a patient with a high-risk ductal infiltrating carcinoma of the breast who received high-dose chemotherapy (HDC) with peripheral blood progenitor cell (PBPC) rescue. The patient received G-CSF after PBPC for a faster granulocyte recovery. She developed a cutaneous eruption located on back, buttocks, axillae, groin and sites where electrocardiography electrodes had been placed. From the histopathological point of view, the eruption was characterized by the presence of numerous large, atypical histiocytes in the dermis with several mitotic figures, mimicking involvement of the dermis by a malignant process.

Vaccination with irradiated
granulocyte-macrophage colony-stimulating factor
(
GM-CSF
)-secreting gene-transduced cancer vaccines induces tumoricidal immune responses. In a Phase I human gene therapy trial, eight immunocompetent prostate cancer (PCA) patients were treated with autologous,
GM-CSF
-secreting, irradiated tumor vaccines prepared from ex vivo retroviral transduction of surgically harvested cells. Expansion of primary cultures of autologous vaccine cells was successful to meet trial specifications in 8 of 11 cases (73%); the yields of the primary culture cell limited the number of courses of vaccination. Side effects were pruritus, erythema, and swelling at vaccination sites. Vaccine site biopsies manifested infiltrates of dendritic cells and macrophages among prostate tumor vaccine cells. Vaccination activated new T-cell and B-cell immune responses against PCA antigens. T-cell responses, evaluated by assessing delayed-type hypersensitivity (DTH) reactions against untransduced autologous tumor cells, were evident in two of eight patients before vaccination and in seven of eight patients after treatment. Reactive DTH site biopsies manifested infiltrates of effector cells consisting of CD45RO+ T-cells, and degranulating eosinophils consistent with activation of both Th1 and Th2 T-cell responses. A distinctive eosinophilic
vasculitis
was evident near autologous tumor cells at vaccine sites, and at DTH sites. B-cell responses were also induced. Sera from three of eight vaccinated men contained new antibodies recognizing polypeptides of 26, 31, and 150 kDa in protein extracts from prostate cells. The 150-kDa polypeptide was expressed by LNCaP and PC-3 PCA cells, as well as by normal prostate epithelial cells, but not by prostate stromal cells. No antibodies against prostate-specific antigen were detected. These data suggest that both T-cell and B-cell immune responses to human PCA can be generated by treatment with irradiated,
GM-CSF
gene-transduced PCA vaccines.

Chronic neutropenia with autoimmune diseases is associated mainly with rheumatoid arthritis (RA), as Felty's syndrome or large granular lymphocyte (LGL) leukemia, and with systemic lupus erythematosus (SLE). Recent advances have allowed better understanding regarding the mechanism of neutropenia and improved options for treatment. Target antigens for antineutrophil antibodies have been identified for both Felty's syndrome and for SLE. The role of soluble Fas-ligand (FasL) in inducing apoptosis of neutrophils has been clarified for LGL leukemia and increased neutrophil apoptosis has been described in neutropenic patients with SLE. The role of immune complexes in affecting neutrophil traffic and function continues to be studied. Treatments of neutropenia have included methotrexate, cyclosporine A, and granulocyte colony-stimulating factor (G-CSF) as well as
granulocyte-macrophage colony-stimulating factor
(
GM-CSF
). The efficacy of both GM- and G-CSF in reversing neutropenia and decreasing the risk of infections in Felty's syndrome and SLE has been well documented. Of concern, however, have been flares of symptoms or development of leukocytoclastic
vasculitis
in some patients following the use of these cytokines. Recent results suggest that in these patients G-CSF should be administered at the lowest dose effective at elevating the neutrophil count above 1,000/microL.

A phase I study of
granulocyte-macrophage colony-stimulating factor
(
GM-CSF
) gene-transduced tumor vaccine for patients with metastatic renal cell carcinoma (RCC) was initiated in 1998, as the first cancer gene therapy in Japan. The study is still ongoing, but the first patient is presented here as a case report. The patient was a 60-year-old man with Stage IV CRC with multiple lung metastases. After surgical resection of the tumor, autologous tumor cells were transduced and cultured to produce
GM-CSF
. The patient received a total of 2.2 x 108 gene-transduced autologous vaccine cells by subcutaneous injection. During the course of vaccination, growth of the largest metastatic mass slowed to some extent; however, multiple new lesions developed. About 1 month after the start of low-dose IL-2 therapy, rapid and remarkable regression in a large lung hilar metastatic mass was noticed. The patient died of progressive disease 7 months after the start of
GM-CSF
gene therapy. Careful histological examination by autopsy revealed that the responding mass was infiltrated by CD8 positive dominant T lymphocytes, and did not exhibit
vasculitis
or any other changes associated with active autoimmune disease.

Several compelling lines of evidence suggest an important influence of genetic variation in susceptibility to Kawasaki disease (KD), an acute
vasculitis
that causes coronary artery aneurysms in children. We performed a family-based genotyping study to test for association between KD and 58 genes involved in cardiovascular disease and inflammation. By analysis of a cohort of 209 KD trios using the transmission disequilibrium test, we documented the asymmetric transmission of five alleles including the interleukin-4 (IL-4) C(-589)T allele (P=0.03). Asymmetric transmission of the IL-4 C(-589)T was replicated in a second, independent cohort of 60 trios (P=0.05, combined P=0.002). Haplotypes of alleles in IL-4,
colony-stimulating factor 2
(
CSF2
), IL-13, and transcription factor 7 (TCF7), all located in the interleukin gene cluster on 5q31, were also asymmetrically transmitted. The reported associations of KD with atopic dermatitis and allergy, elevated serum IgE levels, eosinophilia, and increased circulating numbers of monocyte/macrophages expressing the low-affinity IgE receptor (FCepsilonR2) may be related to effects of IL-4. Thus, the largest family-based genotyping study of KD patients to date suggests that genetic variation in the IL-4 gene, or regions linked to IL-4, plays an important role in KD pathogenesis and disease susceptibility.

Proteinase 3 (PR3) is a major autoantigen in anti-neutrophil cytoplasmic antibodies (ANCA)-associated systemic
vasculitis
(AASV), and the proportion of neutrophils expressing PR3 on their membrane (mPR3+) is increased in AASV. We have shown recently that mPR3 and CD177 are expressed on the same cells in healthy individuals. In this study we try to elucidate mechanisms behind the increased mPR3 expression in AASV and its relationship to CD177. All neutrophils in all individuals were either double-positive or double-negative for mPR3 and CD177. The proportion of double-positive neutrophils was increased significantly in AASV and systemic lupus erythematosus patients. The proportion of mPR3+/CD177+ cells was not correlated to general inflammation, renal function, age, sex, drug treatment and levels of circulating PR3. AASV patients had normal levels of granulocyte colony-stimulating factor and
granulocyte-macrophage colony-stimulating factor
. Pro-PR3 was found to constitute 10% of circulating PR3 but none of the mPR3. We found increased mRNA levels of both PR3 and CD177 in AASV, but they did not correlate with the proportion of double-positive cells. In cells sorted based on membrane expression, CD177-mRNA was several-fold higher in mPR3+ cells. When exogenous PR3 was added to CD177-transfected U937 cells, only CD177+ cells bound PR3 to their membrane. In conclusion, the increased membrane expression of PR3 found in AASV is not linked directly to circulating PR3 or PR3 gene transcription, but is dependent upon CD177 expression and correlated with the transcription of the CD177 gene.
