OBJECTIVETo assess changes of liver function in HIV-positive children with/without HBV/ HCV co-infection after 1 year of highly active antiretroviral therapy (HARRT).

METHODSSeventy-eight pediatric AIDS patients with HBV/HCV co-infection,19 pediatric AIDS patients with HBV co-infection and 44 pediatric AIDS patients without HBV/HCV co-infection who received HAART at least for 1 year were enrolled. HIV-1 viral load was quantitatively detected using a standardized reverse transcriptase-polymerase chain reaction assay, and blood cells were determined by three-color flow cytometry. Anti-HCV antibody and HBsAg was detected using an enzyme-linked immunosorbent technique, and ALT, AST and TBIL were detected by automatic biochemical analyzer.

RESULTSAfter 1 year-HAART, the viral load was decreased to the lowest limit of detection in 90.34% patients (t=2.61, P<0.01), and CD4+ T cell counts were increased from 170.187±132.405/ μl to 796.014±158.491/ μl (t=3.17, P<0.01). The levels of ALT and AST were elevated (t=2.02, P<0.05), while the ALT and AST levels in patients receiving nevirapine (NVP) based HAART increased from 18.28±13.74 U/L and 24.23±8.09 U/L to 55.35±22.40 U/L and 69.97±26.72 U/L, respectively(t=3.80,t=4.11;Ps<0.01). The increment of ALT and AST in NVP based HAART were significantly higher than that in the efavirenz based HAART (ALT:46.28±13.35 U/L vs 37.70±15.25 U/L and AST:19.53±7.23 U/L vs 1.25±0.21 U/L, respectively; t=4.53, t=5.79; Ps<0.01), particularly in patients co-infected with HIV/HBV/HCV (ALT:54.32±22.85 U/L vs 16.89±14.42 U/L and AST:41.71±19.26 U/L vs -3.44±15.59 U/L, respectively; t=3.42, t=2.98, Ps<0.01).

CONCLUSIONHARRT can repress HIV-1 replication effectively, but it also cause the damage of liver function, especially in patients with HBV and/or HCV co-infection.

Chronic liver disease represents a major public health problem, accounting for significant morbidity and mortality worldwide. As prognosis and management depend mainly on the amount and progression of liver fibrosis, accurate quantification of liver fibrosis is essential for therapeutic decision-making and follow-up of chronic liver diseases. Even though liver biopsy is the gold standard for evaluation of liver fibrosis, non-invasive methods that could substitute for invasive procedures have been investigated during past decades. Transient elastography (TE, FibroScan(R)) is a novel non-invasive method for assessment of liver fibrosis with chronic liver disease. TE can be performed in the outpatient clinic with immediate results and excellent reproducibility. Its diagnostic accuracy for assessment of liver fibrosis has been demonstrated in patients with chronic viral hepatitis; as a result, unnecessary liver biopsy could be avoided in some patients. Moreover, due to its excellent patient acceptance, TE could be used for monitoring disease progression or predicting development of liver-related complications. This review aims at discussing the usefulness of TE in clinical practice.

OBJECTIVETo analyze the clinical features of interstitial pneumonitis (IP) associated with interferon therapy for chronic hepatitis C.

METHODSWe report the first case of IP in China resulting from pegylated interferon alpha-2a in combination with ribavirin for treatment of hepatitis C viral infection. A statistical analysis of the related literatures documenting such IP cases was performed using SPSS 11.5 software.

RESULTSOf the 22 patients reported to develop IP after interferon therapy alone or in combination with ribavirin, 83%, 72% and 56% of the patients had the symptoms of dyspnoea, dry cough and fever, respectively. Twenty of these cases presented with restrictive pulmonary functional impairment and/or hypoxemia, and diffuse infiltration on chest radiography and/or CT. Complications were documented in 71% of the cases within 12 weeks of the treatment. The majority (85%) of the patients had favorable prognoses with an average recovery time of 7.5 weeks. Compared with the patients with mild and moderate pulmonary function impairment, 8 patients with severe pulmonary functional impairment had early onset of IP during the interferon therapy (6.6 vs 14.1 weeks, P<0.05), and a higher rate of corticosteroid treatment (75% vs 54%, P>0.05).

CONCLUSIONIP is a rare pulmonary complication associated with IFN therapy, and patients with chronic hepatitis C should be followed up closely in the first 12 weeks of interferon therapy. Prompt discontinuation of medication is mandatory in the presence of IP, and corticosteroid therapy may not be essential for patients with mild or moderate pulmonary functional impairment under close monitoring. The severity of pulmonary damage is associated with the time of complication occurrence, and corticosteroids are required when obvious pulmonary toxicity occurs in early stage of the treatment (within 6 weeks) to reduce the pulmonary damage.

OBJECTIVETo analyze the frequency of thyroid dysfunction and determine its influencing factors in chronic hepatitis C (CHC) patients treated with pegylated-interferon alpha (peg-IFNa)-2a and ribavirin (RBV) combination therapy.

METHODSA total of 194 CHC patients were treated with peg-IFNa-2a and RBV for 48 weeks. Development of thyroid dysfunction was recorded. Clinical and biological factors from pre-treatment (baseline) to post-treatment were statistically analyzed to determine correlation with thyroid dysfunction in this patient population.

RESULTSFifty-two (26.80%) of 194 peg-IFNa-2a/RBV-treated patients developed thyroid dysfunction. Dysfunction severity ranged from hyperthyroidism (n = 1, 0.52%) and hypothyroidism (n = 10, 5.15%) to subclinical hyperthyroidism (n = 4, 2.06%) and subclinical hypothyroidism (n = 37, 19.07%). The dysfunction rate was significantly higher after peg-IFNa-2a/RBV treatment (26.80% vs. 12.37% at baseline, x2 = 12.829, P less than 0.05, odds ratio (OR) = 0.386, 95% confidence interval (CI): 0.226-0.657), in females (33.00% vs. 20.21% in males, P less than 0.05, 95% CI: 1.016-3.040), and in thyroid auto-antibody positive patients (64.29% vs. 23.89% in negative patients, P less than 0.05, 95% CI: 1.681-36.183). Early virological response did not have any significant effect on dysfunction rate (23.00% vs. 30.85% no early virological response, x2 = 1.522, P more than 0.05) nor did end of treatment response (27.19% vs. 26.25% no response at end of treatment, x2 = 0.021, P more than 0.05). Patients who developed thyroid dysfunction had higher interleukin (IL)-6 at baseline (i.e. before peg-IFNa-2a/RBV treatment) (27.08+/-14.90 vs. 11.65+/-5.46 in patients who maintained normal thyroid function, t = 3.127, P less than 0.05, 95% CI: 5.28-25.58). IL-6 levels were not significantly different between the two groups at 24 weeks (6.30+/-2.47 vs. 6.81+/-2.80, t = 0.352, P more than 0.05). IL-6 levels before and after 48 weeks of treatment in normal thyroid function patients were 27.08+/-14.90 and 6.30+/-2.47, t = 3.632, P less than 0.05, and in thyroid dysfunction patients were 11.65+/-5.46 and 6.81+/-2.80, t = 1.997, P more than 0.05.

CONCLUSIONPeg-IFNa-2a/RBV combination therapy may cause thyroid dysfunction, especially hypothyroidism, in CHC patients. Female sex and thyroid auto-antibody positivity may put CHC patients at higher risk of developing thyroid dysfunction during peg-IFNa-2a/RBV therapy. Elevated IL-6 may be a predictive marker of peg-IFNa-2a/RBV-induced thyroid dysfunction.

BACKGROUND/AIMS: Thyroid dysfunction (TD) is more likely to occur in patients with chronic hepatitis C (CHC) and is particularly associated with interferon (IFN) treatment. The purpose of this study was to investigate the incidence, outcomes, and risk factors for TD during pegylated interferon (PEG-IFN) and ribavirin (RBV) combined therapy in patients with CHC. METHODS: A total of 242 euthyroid patients with CHC treated with PEG-IFN/RBV were included. Thyroid function and autoantibodies were measured at baseline, and virologic response and thyroid function were assessed every 3 months during therapy. RESULTS: TD developed in 67 patients (27.7%) during the PEG-IFN/RBV treatment. The types of TD were subclinical hypothyroidism (50.7%), hypothyroidism (14.9%), thyroiditis (11.9%), subclinical hyperthyroidism (10.4%), and hyperthyroidism (10.4%). Most of the patients with TD recovered spontaneously; however, seven patients (10.4%) needed thyroid treatment. The sustained virological response rate was higher in patients with TD than those without (65.7% vs. 49.1%, p = 0.02). Baseline thyroid stimulating hormone (TSH) concentrations (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.96 to 8.77; p < 0.001), presence of the thyroid peroxidase antibody (OR, 8.81; 95% CI, 1.74 to 44.6; p = 0.009), and PEG-IFNalpha-2b (OR, 3.01; 95% CI, 1.43 to 6.39; p = 0.004) were independent risk factors for the development of TD. CONCLUSIONS: TD developed in 27.7% of patients with CHC during PEG-IFN/RBV treatment, and 10.4% of these patients needed thyroid treatment. TD is associated with a favorable virologic response to PEG-IFN/RBV. Assessment of TSH and thyroid autoantibodies at baseline and close monitoring of thyroid function during PEG-IFN/RBV therapy are necessary for early detection and management of IFN-induced TD.

OBJECTIVETo evaluate the efficacy of kushenin in treating patients with chronic hepatitis C after renal transplantation.

METHODSFifty-five patients were randomly assigned by lottery to the treatment group (29 cases) and control group (26 cases). The same immunosuppression therapy was given to all patients in both groups. Patients in the treatment group were treated with kushenin 0.6 g once a day, while those in the control group were treated with conventional liver protective agents such as vitamins. The treatment duration of both groups was 3 months. The incidences of serious hepatitis and acute rejection reaction, serum biochemistry parameters including indicators of liver and kidney functions, hepatic fibrosis index, and serum HCV-RNA were compared between the two groups.

RESULTS(1) The incidence of serious hepatitis in the treatment group and the control group was 3.45% (1/29 cases) and 11.54% (3/26 cases), respectively, which was insignificantly different between the two groups (P=0.335). (2) The incidence of acute rejection in the treatment group was 6.90% (2/29 cases) and that in the control group was 7.69% (2/26 cases), showing insignificant difference (P=0.335). (3) The differences in serum alanine aminotransferase (ALT), direct bilirubin (DBIL), hyaluronic acid (HA), propeptide collagen type III (PC III), laminin (LN), collagen type IV (Col IV) levels between the two groups were insignificant before transplantation (P>0.05), while the above-mentioned parameters in the treatment group were significantly lower than those in the control group after transplantation (P<0.05). The difference in serum creatinine (SCr) and endogenous creatinine clearance rate (CCr) between the two groups was insignificant before and after transplantation (P>0.05). (4) The negative conversion rate of HCV-RNA in the treatment group was 31.03% (9/29 cases), significantly higher than the value of 11.54% (3/26 cases) in the control group after transplantation (P<0.05). (5) The levels of serum ALT and DBIL in patients with HCV-RNA converted to negative were significantly lower than those with still-positive HCV-RNA (P<0.05).

CONCLUSIONSKushenin has a certain effect on inhibiting the proliferation of HCV, protecting liver cells, and anti-liver fibrosis. On the other hand, it has no obvious influence on renal allograft function. Thus, the drug is clinically safe and effective for use in treating patients with chronic hepatitis C after renal transplantation.
