Evaluation of prognostic value of cell adhesion molecules in chronic hepatitis C therapy

The most reliable determination of severity and prognosis in chronic viral hepatitis is the histological staging of the disease, which comprises an invasive procedure and is often not well accepted by patients. The search for alternative non-invasive methods is mandatory especially in follow-ups after initial assessment by biopsy. The aim of this study was to evaluate the role of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) in patients under interferon alpha therapy whether responsive or non-responsive to therapy. Thirty chronic hepatitis C patients (CHC) under combined therapy of interferon-α with ribavirin, whether responsive or non-responsive, were included in the study as well as ten healthy controls. Serum VCAM-1 and ICAM-1 levels were calculated using commercial enzyme linked immunosorbent assay (ELISA) kits. Before the therapy, sICAM-1 and sVCAM-1 levels were significantly higher among CHC patients (96.9 ± 39.74 and 679.4 ± 218.98 ng/mL, respectively) than in the control group (14.3 ± 4.32 and 108.9 ± 49.21 ng/mL, respectively), (p < 0.05 for both). They were higher among non-responsive than in responsive patients. Comparisons in soluble ICAM-1 (sICAM-1) levels of responsive persons during treatment revealed a statistically significant increase at baseline (81.27 ± 25.797) versus its value after one month (52.33 ± 12.76), p < 0.05 and after three months (49.67 ± 14.42), p < 0.05. However, no statistically significant difference was detected between one and three-month sICAM-1 levels post-therapy commencement (p = 0.055). Also, no statistically significant difference was detected between sVCAM-1 levels at baseline (521.47 ± 137.29) versus three months after therapy initiation (517.53 ± 130.6), p = 0.854. The occurrence of a significant decrease in sICAM-1 level as early as one month after therapy in responsive patients only allows us to conclude that sICAM-1 could be used as an early marker in CHC patients under interferon therapy to predict prognosis and guide the treatment, whereas sVCAM-1 does not present any difference between the studied groups.(AU)

Correlation between serum levels of interleukins 10 and 12 and thrombocytopenia in hepatitis C cirrhotic (class A) patients

Hepatitis C virus (HCV) patients commonly have low platelet counts; however, the exact role of HCV infection in thrombocytopenia is unknown. This work aimed to study the serum levels of interleukins (IL) 10 and 12 in patients with mild and moderate thrombocytopenia associated with chronic hepatitis C infection. Our study included 15 patients with chronic HCV infection and newly diagnosed isolated autoimmune thrombocytopenia (Group I) and 15 patients with chronic HCV infection and normal platelet count as controls (Group II). All patients were examined for personal history and clinical aspects, complete blood count, bone marrow aspiration, liver function tests, HCV antibody assay by ELISA and polymerase chain reaction (PCR), abdominal ultrasound, Helicobacter pylori stool antigen test, evaluation of serum levels of IL-10, IL-12 and platelet specific antibodies. Our results revealed that eight patients from Group l had mild thrombocytopenia and seven patients had moderate thrombocytopenia. Serum IL-10 level was significantly elevated (t = 9.301, p < 0.001) while serum IL-12 showed a significant decrease (t = 6.502, p < 0.001) in Group I compared to the control group. No correlation was detected between platelet counts and the serum levels of either IL-10 [r = 0.454, p = 0.089 (Group I), r = 0.038, p = 0.89 (Group II)] or IL-12 [r = 0.497, p = 0.06 (Group I), r = 0.499, p = 0.058 (Group II)]. However, in Group I, a significant correlation was present only between moderate thrombocytopenia and serum levels of either IL-10 (r = 0.794, p = 0.033) or IL-12 (r = 0.967, p = 0.001), while no correlation was detected between these interleukin parameters and mild thrombocytopenia (r = 0.311 and p = 0.453 for IL-10 and r = -0.08 and p = 0.851 for IL-12). Based on our data, we may conclude that interleukins 10 and 12 are involved in low platelet levels.(AU)
