Abstract
INTRODUCTION One of the etiologies of non-Hodgkin lymphoma (NHL) is chronic infection related to lymphoma pathogenesis, with a high prevalence of hepatitis C virus (HCV) infection seen. In determining the treatment and prognosis of NHL, cluster of differentiation 30 (CD30) immunohistochemical staining plays an important role. High levels of CD30 are found in patients with HCV infection. This study aimed to determine the prevalence of CD30 and HCV expression and its correlation with clinicopathological characteristics of Indonesian diffuse large B-cell lymphoma (DLBCL) patients. METHODS A total of 86 formalin-fixed paraffin-embedded (FFPE) samples of DLBCL cases were collected over the course of two years from the Anatomical Pathology department at Dr. Sardjito General Hospital in the special region of Yogyakarta, Indonesia. Immunohistochemistry was performed to detect the two markers (CD30 and HCV). Chi-square tests were used to investigate the correlations between CD30 expression and clinicopathological features in DLBCL patients. RESULTS The positivity rate of CD30 expression in 86 DLBCL samples was 25.6% (22/86) when using a 0% cut-off, and 7.0% (6/86) while using a 20% cutoff. The positivity rate of HCV expression in DLBCL samples was 34.9% (30/86). Positive CD30 expression, HCV expression and clinicopathological features (age, sex, Ann Arbor stage, extranodal involvement, and morphological variations) did not have statistically significant relationships (p>0.05). CONCLUSION There was no statistically significant correlation between CD30 immunoreactivity (cut-off >0% or >20%) and HCV NS3 expression and clinicopathological features (age, sex, Ann Arbor stage, extranodal involvement, lactate dehydrogenase, Eastern Cooperative Oncology Group status and morphological variants) in DLBCL.

Abstract
Background: Even without treatment, most acute hepatitis E virus (HEV) infected patients resolve HEV but sometimes the disease leads to acute liver failure, chronic infection, or extrahepatic symptoms. The mechanisms of HEV pathogenesis appear to be substantially immune mediated. However, the immune responses to HEV are not precisely identified. Objectives: This study aimed to evaluate the Th1/Th2 ratio by investigating serum soluble markers from Th1 and Th2 cells in acute HEV infected patients. Patients and Methods: This case-control study included 35 acute HEV infected patients and 35 age and gender matched anti-HEV negative healthy controls. The serum levels of Interferon (IFN)-γ, IL-4, soluble CD26 (sCD26) and sCD30 were determined by the enzyme-linked immunosorbent assay. Results: The results showed a significant difference in IFN-γ and sCD26 (P < 0.0001 and P = 0.001) yet not IL-4 and sCD30 (P = 0.354 and P = 0.159) between acute HEV patients and controls, respectively. There was a positive direct correlation between serum levels of sCD26 and IFN-γ in acute HEV patients (r = 0.64, P = 0.001). In addition, the ratio of sCD26/sCD30 in the acute HEV group was more than two folds higher than in the HEV negative controls. Conclusions: Acute HEV infection shows a pattern of Th1-type immune response, and the direct significant positive correlation between the serum level of sCD26 and IFN-γ in acute HEV infected patients, suggests that the trend of sCD26 levels is a valuable marker for predicting hepatic inflammation in hepatitis E.

Abstract
INTRODUCTION Hepatitis B is a major health problem with serious consequences. In hepatitis B treatment host cellular immune responses have a determinant role and T helper cells are the main active members of immune system against virological infection. The aims of this study are to investigate response rate of patients to INF-α therapy and evaluation of sCD26 and sCD30 roles as presenters of T cells activities in predicting the outcome of therapy in chronic hepatitis B patients. METHODS AND MATERIALS Fifty three chronic hepatitis B patients received IFN-α 9 MU S.C three times weekly for 24 weeks, and were followed up for 24 weeks. Serum levels of sCD26 and sCD30, before, 1 and 3 months after treatment commencement were evaluated in 53 chronic hepatitis B patients and 30 healthy individuals as control group. RESULTS Normal level of ALT was seen in 64.1% (34/53) of patients and undetectable DNA was observed in 39.6% (21 out of 53) of them. Finally, 33.9% (18/53) of patients obtained sustain virological response. CD26 levels changes was correlated with response to treatment and significantly (p<0.001) increased during first 3 months of treatment among patients with successful response to therapy. CONCLUSION Interferon is an effective and safe treatment for chronic hepatitis B patients and sCD26 serum level changes might be useful in predicting the outcome of therapy in naïve chronic hepatitis B patients undergoing treatment with IFN-α, as it can help clinicians for withdrawing non-responder patients for prevention of adverse events and economical burden.

Abstract
Background We aimed to investigate the effects of ribavirin on hepatitis C virus (HCV). Immunological and virological effects were analysed in patients undergoing treatment with ribavirin monotherapy prior to the initiation of combination therapy with interferon-α. Methods A total of 25 patients with chronic HCV infection were enrolled in this study. All patients received ribavirin for 4 weeks during monotherapy; subsequently, interferon-α2b was additionally given as combined therapy. Patients were divided into two groups according to virological response. A rapid viral responder (RVR) was defined as a patient in whom HCV RNA became undetectable within 4 weeks after combination therapy. The changes of the T-helper (Th)1/Th2 subset of peripheral blood CD4+ T-cells, serum cytokine levels and the alignment of the interferon sensitivity- determining region (ISDR) during ribavirin monotherapy were analysed by flow cytometry, ELISAs and sequencing methods. Results A total of 17 patients were classed as RVR. In the RVR group, the mean ±sd serum alanine aminotransferase levels significantly decreased (before treatment 103 ±92 IU/l and after treatment 57 ±46 IU/l; P<0.05) during ribavirin monotherapy. The mean ±sd Th1/Th2 ratio significantly increased (before treatment 13.9 ±5.1 and after treatment 16.7 ±6.2; P<0.05), but did not change in the non-RVR group. The levels of Th2 cytokines (interleukin-10 and soluble CD30) significantly decreased, especially in the RVR group. The mean ±sd mutation rates of ISDR at the nucleotide level increased in the RVR group (before treatment 2.6 ±0.9 sites/clone and after treatment 3.9 ±1.6 sites/clone; P<0.05), but did not change in the non-RVR group. Conclusions Ribavirin administration might increase the efficacy of interferon therapy for patients with chronic hepatitis C by stimulating the host immune system and promoting HCV gene mutation.

Abstract
Hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT) significantly accelerates progression to allograft cirrhosis. Current biochemical parameters to monitor progression of chronic HCV after OLT have yielded low specificity and sensitivity. Here we investigated the HCV-specific immunity and serum levels of soluble CD30 (sCD30), a novel marker of Th2 immunity, in patients with and without allograft cirrhosis. Patients with hepatic inflammation but no cirrhosis (HIN, n=20) revealed elevated serum interferon (IFN)-gamma and high frequency of IFN-gamma producing CD4 T(h1) cells compared to those with hepatic cirrhosis (HFC, n=20) that had high interleukin (IL)-5 and IL-5 producing CD4 T(h2) cells. Patients with HFC, but not HIN, were found to have significantly higher levels of sCD30. Therefore, we conclude that lack of optimal Th1-type CD4 T cells is associated with HCV-induced allograft cirrhosis. Further, sCD30 may represent a novel marker for surveillance of hepatic cirrhosis in transplant recipients with chronic HCV infection.

Abstract
A nested case-control study was conducted to examine the association between host immune status, as characterized by serum immune marker levels, and the development of hepatocellular carcinoma (HCC) up to 8 years later in persons with chronic hepatitis C virus (HCV) infection. Cases (n = 39) and matched controls (n = 117) were selected from participants of the Town C HCV Study in Japan between 1996 and 2004 and matched on age at first available sample (+/-1 year), gender, and length of follow-up. Separate analyses were done for each of three serum immune markers: soluble tumor necrosis factor-receptor II (sTNF-R2) and soluble intercellular adhesion molecule-1 (sICAM-1), as indicators of type 1, cell-mediated immune response, and soluble CD30 (sCD30), as an indicator of type 2, humoral immune response. The median concentrations of sTNF-R2, sICAM-1, and sCD30 among controls were 3,170 pg/mL, 305 ng/mL, and 3.0 units/mL, respectively, and were higher among cases (3,870 pg/mL, 372 ng/mL, and 3.3 units/mL, respectively). The risk of developing HCC among subjects with immune marker concentrations above the median levels of the controls was >2-fold greater than among subjects with lower concentrations for all three markers [sTNF-R2: odds ratio (OR), 6.9; 95% confidence interval (95% CI), 2.4-20.5; sICAM-1: OR, 2.0; 95% CI, 0.9-4.1; and sCD30: OR, 2.1; 95% CI, 1.0-4.7]. Simultaneous adjustment for all three markers revealed only sTNF-R2 to be associated with HCC risk (OR, 6.4; 95% CI, 2.0-20.6). Adjustment for alcohol consumption and HCV serotype did not materially alter these associations. Results from this prospective, community-based study suggest that a dysregulation in both type 1-related and type 2-related host immunity contributes to the development of HCV-associated HCC.

Abstract
OBJECTIVE Leishmania tropica is the causative agent of anthroponotic cutaneous leishmaniasis (CL) in Iran. The disease often heals within a year; however, the non-healing forms of disease are also known. The aim of the present study was the determination of the levels of soluble (s) CD26 and CD30 co-stimulatory molecules in sera of L. tropica-infected individuals. The correlations of sCD26 and sCD30 levels with clinical presentation of the disease were assessed. METHODS The levels of sCD26 and sCD30 were determined by a sandwich enzyme-linked immunosorbent assay in sera from patients with acute and non-healing presentation of disease. RESULTS The serum level of sCD26 was significantly higher in non-healing patients than in cases with acute CL (P<0.001). There was no significant difference in sCD26 level between patients with acute CL and healthy controls. However, the levels of sCD30 in sera from all L. tropica-infected individuals were higher than controls (P<0.001). A significant difference was also found in sCD30 level between non-healing cases and patients with acute CL (P<0.001). CONCLUSION These findings suggest sCD30 is more relevant to clinical manifestation of cutaneous leishmaniasis than sCD26. The high sCD26 and sCD30 levels in non-healing patients reflect the presence of mixed Th1- and Th2-type responses in these patients.

Abstract
BACKGROUND Clearance of hepatitis C virus (HCV) is attributed to host cellular immune responses, in which T helper cells play a critical role. The purpose of the present paper was therefore to study the serial changes of serum soluble markers released from T helper 1 (Th1) and 2 (Th2) and their correlations with treatment responses in chronic hepatitis C patients receiving interferon-alpha plus ribavirin for 24 weeks. METHODS Serum markers (soluble CD26 and CD30 levels) of T helper cells were quantified before and 6 months after combination therapy in 33 chronic hepatitis C patients and in 20 healthy controls. RESULTS Compared to healthy controls, chronic hepatitis C patients had significantly lower serum soluble CD26 levels before (140.4 +/- 63.9 ng/mL vs 200.6 +/- 60.3 ng/mL, P < 0.0001) and after (115.9 +/- 32.9 ng/mL vs 200.6 +/- 60.3 ng/mL, P < 0.0001) combination therapy. The level was even lower in those with non-sustained virologic response (non-SVR; 139.0 +/- 50.9 ng/mL vs 117.7 +/- 40.3 ng/mL, P = 0.039). In contrast, soluble CD30 levels at 6 months after combination therapy were significantly lower in patients with SVR than those with non-SVR (6.4 +/- 3.5 U/mL vs 10.4 +/- 5.4 U/mL, P = 0.021). CONCLUSION Chronic hepatitis C patients have a weak Th1 response as reflected by lower soluble CD26 levels and the levels are even lower in non-sustained responders. In sharp contrast, downregulation of Th2 response with serial changes of soluble CD30 level is associated with successful treatment of HCV infection.

Abstract
Rapid progression of hepatitis C virus (HCV) disease in patients with HIV/HCV may reflect different cytokine responses and be influenced by HCV genotype. This is addressed by a study of patients with HIV/HCV coinfection and infection with HCV genotype 2 or 3 (2/3). They are compared with coinfected patients infected with genotype 1 and HCV monoinfected patients matched for HCV genotype. IFN-gamma, IL-10, IL-4 and IL-4delta2 mRNA were quantified by real-time PCR in unstimulated PBMC and after in vitro stimulation with HCV core or nonstructural 3/4A antigen. In unstimulated PBMC, levels of IFN-gamma and IL-4 mRNA were lowest in HIV/HCV genotype 1 patients, intermediate in HIV/HCV genotype 2/3 patients and highest in HCV genotype 2/3 patients. Neither HCV genotype nor HIV affected levels of IL-10 mRNA in unstimulated PBMC or IFN-gamma, IL-4 and IL-10 mRNA in PBMC stimulated with HCV antigens. Levels of IL-4 and IL-4delta2 mRNA correlated in mitogen-stimulated PBMC from all patient groups but both were low in HIV/HCV genotype 1 patients. Serum soluble CD30 levels (a putative marker of a T2 cytokine environment) did not differ between patient groups. The data do not suggest a shift in the T1/T2 balance driven by HIV coinfection or HCV genotype but either may affect IL-4 bioavailability.

Abstract
Leishmania infantum is the causative agent of zoonotic visceral leishmaniasis (VL). If untreated the disease could be fatal; however, in some cases the infection can run a subclinical course. In subclinical infections a Th1-response predominates, while Th2-responses and/or probably Treg cells are related to unfavourable outcome of the disease in active VL. In the present study we determined the levels of soluble (s) CD26 and CD30 co-stimulatory molecules in sera from patients with active VL, asymptomatic individuals and healthy volunteers. Results showed a significant difference in both sCD26 and sCD30 between infected cases and normal individuals (P < or = 0.001). However, there was no significant difference in sCD26 levels between asymptomatic cases and patients, although the difference was not significant. sCD30 levels were significantly higher in VL patients than asymptomatic cases (P < or = 0.001). These findings suggest a possible association between sCD26 and sCD30 levels and the clinical manifestation of L. infantum infection.

Abstract
Hepatitis C has emerged as a major worldwide public health problem. The host immune response to HCV infection is composed of both a non-specific immune response, including interferon (IFN) production and natural killer (NK) cell activity, and a virus-specific immune response, including humoral and cellular components. Susceptibility to infection has been related to immunological disturbances. Several studies have provided experimental evidence of disorders of both cellular and humoral immunity. The present study was carried out to evaluate the serum immunoglobulins level (IgG, IgM, IgA) and IgG-subclasses (IgG1-4) in chronic hepatitis C patients in comparison with healthy control patients. This study included 50 patients with biochemical, serologic, virologic, and histologic evidence of chronic hepatitis C. Total IgG, IgA, and IgM were assayed by nephelometry. IgG subclasses were assayed using human IgG subclasses enzyme immunoassay. The results showed a significant increase of total serum IgG and IgM levels found in patients with chronic HCV compared with the healthy control patients (P < 0.001 for each). There was a statistically significant difference in the IgG subclasses (IgG1 to IgG4) between the patients and controls (P < 0.001 for each). On the other hand, no significant difference was found between patients and healthy controls in IgA level (P = 0.4). The normal total serum immunoglobulins pattern is apparently shifted in chronic hepatitis C infection in the Egyptian patients. This pattern may include an ethnic or biologic background and could be used in the differentiation of the patients with minimal liver disease.

Abstract
It has been suggested that soluble CD30 (sCD30) serum levels in chronic hepatitis C are correlated with the activity of the disease and with the outcome of interferon (IFN) treatment. In this study, sCD30 serum levels in 25 patients with chronic hepatitis C, before and after treatment with IFN-2alpha, were measured. A total of 20 healthy subjects were used as controls. High sCD30 levels in serum were found in 36% of patients and in 5% of controls. In patients with sCD30 levels above or within the normal range, no significant differences in age, gender, serum transaminases and histology activity index were found. In relation to IFN treatment, only responder patients had serum sCD30 higher than controls, although the difference between responders and non-responders was not significant. No changes from baseline values were observed after treatment. Although high, sCD30 serum levels in chronic hepatitis C are not correlated with the disease activity, are not affected by IFN treatment and are not predictors of response to IFN treatment.

Abstract
SUMMARY The relationship between the balance of helper T-cell type 1 (Th1) or type 2 (Th2) cytokines and the clinical course of hepatitis C virus (HCV) infection is unclear. We evaluated Th1 [interleukin (IL)-2, interferon-gamma (IFN-gamma)] and Th2 cytokine (IL-4, IL-10) and 2,5-oligoadenylate synthetase (OAS, an IFN-induced antiviral protein) production by peripheral blood mononuclear cells from 10 healthy anti-HCV-positive individuals (group A), 10 HCV-RNA-positive with persistently normal alanine aminotransferase (ALT) levels (group B), 10 HCV-RNA-positive with abnormal ALT (group C) and 10 uninfected healthy controls. IL-2 production was significantly increased in group B when compared with all the other groups. No difference was found for IFN-gamma. IL-4 was significantly higher in group C than in both group B (P = 0.0006) and controls (P = 0.004). Compared with controls, IL-10 was significantly decreased in group A (P = 0.013) and B (P = 0.004). The production of 2,5-OAS was significantly higher in group B than in A (P = 0.04) and in C (P = 0.004). Finally, in all HCV-RNA-positive patients, a significant correlation was found between ALT and both IL-2 (r = -0.78; P = 0.0008) and IL-4 (r = 0.75; P = 0.0008). IN CONCLUSION (i) subjects who cleared HCV showed a cytokine profile similar to controls; (ii) a preferential shift towards a Th1 profile seems associated with a more favourable clinical outcome in chronic hepatitis C; and (iii) a prevalent Th2 profile seems implicated in HCV pathogenesis and severity of liver disease.

Abstract
Type 1 (T1) cytokine responses are required for the clearance of hepatitis C virus by cytotoxic T lymphocytes, but can promote liver damage. Interferon-alpha (IFN alpha) can be expected to promote T1 cytokine responses, so treatment outcome may depend on the T1/T2 cytokine environment and levels of immune activation at baseline. This model was tested by monitoring immunological markers in a pilot study of treatment naïve patients given IFN alpha 2b and ribavirin, with the aim of finding markers that predict virological outcome. Soluble (s) CD26/dipeptidyl peptidase IV enzyme activity and levels of sCD30, bioavailable IL-6, sTNF-RI, IL-1ra and nitrite/nitrate (NO(2)(-)/NO(3)(-)) were measured. Levels of IL-1ra and bioavailable IL-6 were lower in patients than controls and did not change with therapy. Treatment decreased sCD26/dipeptidyl peptidase IV enzyme activities and sCD30 levels and increased NO(2)(-)/NO(3)(-) levels. High baseline sCD30 levels predicted an early (P = 0.008) and sustained (P = 0.03) virological response to therapy, suggesting treatment may be more effective in patients with a predominant T2 profile.

Abstract
CD30, a member of the tumor necrosis factor receptor (TNFR) family, is a characteristic cell surface receptor for activated T-cells and the malignant cells of Hodgkin's disease (HD), anaplastic large cell lymphoma (ALCL) and a few other non-Hodgkin's lymphomas. As an independent predictor of disease progression and poor prognosis, high serum levels of soluble CD30 (sCD30) have prognostic significance for patients with CD30-positive lymphomas and viral infections. Activation of CD30 by ligand binding or cross-linking with immobilized antibody leads to trimerization of the receptor, recruitment of signaling proteins and transducing of numerous effects. Due to the lack of an intrinsic enzymatic domain, signal transduction is exclusively mediated by the members of the TNFR-associated factor (TRAF) family and the various TRAF-binding proteins. CD30 signaling can induce several pathways including the activation of NFkappaB and the MAP kinases. CD30 mediated signal transduction is capable of promoting cell proliferation and cell survival as well as antiproliferative effects and cell death depending on cell type and co-stimulatory effects. Some data indicate the opposite signaling of CD30 in HD or ALCL cells, while other information point to pleiotropic signaling pathways in both malignancies. The pro and contra of this controversy is discussed in this review.

Abstract
To evaluate the relationship between cytokine balance and responsiveness to interferon-alpha (IFN-alpha), we investigated the production of IFN-gamma, interleukin-10 (IL-10), IL-12 p70, and IL-12 p40 by peripheral blood mononuclear cell (PBMC) cultures from patients with chronic hepatitis C (CHC) before and after 1 year of IFN-alpha treatment. Before the therapy, responder (R) patients exhibited lower IFN-gamma release, higher IL-10 production, and higher values of the IL12 p40/p70 ratio compared with nonresponders (NR). Increased sensitivity to the effects of IL-12 and IL-10, as well as higher IL-12-dependent IFN-gamma secretion, were also found in the R subset. After IFN-alpha therapy, an increase in IFN-gamma production and a decrease in the IL-12 p40/p70 ratio were observed in R patients, whereas opposite results were obtained in the NR group. Finally, the therapy induced downregulation of IL-10 production and cell responsiveness to recombinant IL-12 in all patients. These findings imply that predominance of a T helper 2 (Th2) cytokine profile in CHC patients favors the beneficial effects of IFN-alpha, thus suggesting a therapeutic role for Th1-driven stimulation of immune response. The findings also stress the primary importance of the IL-12 p40 and p70 balance in the modulation of immune responses to hepatitis C virus (HCV).

Abstract
Current evidence suggests that increased expression of Th1-associated cytokines is important for immune-mediated eradication of hepatitis C infection, while an increase in Th2-associated cytokines is associated with persistence of infection. In this study we evaluated the effects of thymosin-alpha1 (TA1), a naturally occurring thymic peptide, and interferon-alpha (IFN-alpha) on cytokine production in peripheral blood mononuclear cells from untreated patients with chronic hepatitis C. We examined the effect of incubation with TA1, IFN-alpha, or both, on production of Th1-associated cytokines (IL-2, IFN-gamma), Th2-associated cytokines (IL-4, IL-10), and synthesis of the antiviral protein 2',5'-oligoadenylate synthetase. TA1 treatment induced a significant increase in production of IL-2 and 2',5'-oligoadenylate synthetase. Smaller increases were also seen after treatment with IFN-alpha, while incubation with TA1 and IFN-alpha together led to an additive or synergistic effect. Incubation with TA1 resulted in a decrease in IL-4 and IL-10, whereas IFN-alpha increased these cytokines. The addition of TA1 to IFN-alpha significantly reversed this IFN-alpha-induced increase. Hence, TA1 treatment could benefit patients with hepatitis C infection by increasing the Th1-type response, fundamental for sustained clearance of hepatitis C; and by decreasing the Th2-type response, associated with persistence of viraemia.
