Ovarian HBV replication following ovulation induction in female hepatitis B carriers undergoing IVF treatment: A prospective observational study

Hepatitis B virus (HBV) can be found in ovarian tissues. This study compared HBV DNA levels in follicular fluid collected during oocyte retrieval with paired serum samples in HBV carriers after ovarian stimulation during IVF treatment for infertility. Sixty‐four HBV carrier women referred to the Assisted Reproductive Units of two Hong Kong hospitals were recruited. At oocyte retrieval, the follicular fluid aspirated from the first follicle was collected for study. In 22 women, the first follicular fluid sample from both ovaries was similarly collected and studied. These women were also tested for liver function test and HBeAg. In 28 (43.8%) women, HBV DNA was detected in follicular fluid and the level correlated with serum levels (Spearman's correlation P < .001). There was concordant detection of HBV DNA in both ovaries, and the levels were significantly correlated (Spearman's correlation P = .029). In 40% of women with FF HBV DNA, the follicular fluid:serum ratio was >1.0, suggesting stimulation of HBV replication. These women also had significantly different liver function test results. Increased HBV replication exists in 40% of women with HBV DNA detected in follicular undergoing ovarian stimulation during IVF treatment.     

Telaprevir- and boceprevir-based tritherapies in real practice for F3-F4 pretreated hepatitis C virus patients

AIM:To assess,in a routine practice setting,the sus-tained virologic response(SVR) to telaprevir(TPV) or boceprevir(BOC) in hepatitis C virus(HCV) nullresponders or relapsers with severe liver fibrosis.METHODS:One hundred twenty-five patients were treated prospectively for 48 wk with TPV or BOC + pegylated-interferon(peg-INF) α2a + ribavirin(PR) according to standard treatment schedules without randomization.These patients were treated in routine practice settings in 10 public or private health care centers,and the data were prospectively collected.Only patients with severe liver fibrosis(Metavir scores of F3 or F4 upon liver biopsy or liver stiffness assessed by elastography),genotype 1 HCV and who were null-responders or relapsers to prior PR combination therapy were included in this study.RESULTS:The Metavir fibrosis scores were F3 in 35(28%) and F4 in 90(72%) of the patients.In total,62.9% of the patients were null-responders and 37.1% relapsers to the previous PR therapy.The overall SVR rate at 24 wk post-treatment withdrawal was 59.8%.The SVR was 65.9% in the TPV group and 44.1% in the BOC group.Independent predictive factors of an SVR included a response to previous treatment,relapsers vs null-responders [OR = 3.9;(1.4,10.6),P = 0.0084],a rapid virological response(RVR) [OR 6.9(2.6,18.2),P = 0.001] and liver stiffness lower than 21.3 kPa [OR = 8.2(2.3,29.5),P = 0.001].During treatment,63 patients(50.8%) had at least one severe adverse event(SAE) of grade 3 or 4.A multivariate analysis identified two factors associated with SAEs:female gender [OR = 2.4(1.1,5.6),P = 0.037] and a platelet count below 150 × 103/ mm3 [OR = 5.3(2.3,12.4),P ≤ 0.001].CONCLUSION:More than half of these difficult-to-treat patients achieved an SVR and had SAEs in an actual practice setting.The SVR rate was influenced by the response to previous PR treatment,the RVR and liver stiffness.     

Tuberculosis and Histoplasmosis among Human Immunodeficiency Virus–Infected Patients: A Comparative Study

In disease-endemic areas, histoplasmosis is the main differential diagnosis for tuberculosis among human immunodeficiency virus (HIV)–infected patients. However, no study has compared the two diseases. Thus, the objective of this study was to compare tuberculosis and histoplasmosis in HIV-infected patients. A population of 205 HIV-infected patients (99 with tuberculosis and 106 with histoplasmosis) hospitalized in Cayenne, French Guiana during January 1, 1997–December 31, 2008 were selected retrospectively from the French Hospital Database on HIV. Multivariate analysis showed that tuberculosis was associated with cough (adjusted odds ratio [AOR] = 0.20, 95% confidence interval [CI] = 0.05–0.73) and a C-reactive protein level > 70 mg/L (AOR = 0.98, 95% CI = 0.97–0.99). Variables associated with disseminated histoplasmosis were a γ-glutamyl transferase level > 72 IU/L (AOR = 4.99, 95% CI = 1.31–18.99), origin from French Guiana (AOR = 5.20, 95% CI = 1.30–20.73), disseminated localization (AOR = 6.40, 95% CI = 1.44–28.45), a concomitant opportunistic infection (AOR = 6.71, 95% CI = 1.50–29.96), a neutrophil count < 2,750 cells/mm³ (AOR = 10.54, 95% CI = 2.83–39.24), a CD4 cell count < 60 cells/mm³ (AOR = 11.62, 95% CI = 2.30–58.63), and a platelet count < 150,000/mm³ (AOR = 19.20, 95% CI = 3.35–110.14). Tuberculosis and histoplasmosis have similarities, but some factors show a greater association with one of these diseases. Thus, adapted therapeutic choices can be made by using simple clinical and paraclinical criteria.     

Excess primary intestinal lymphoproliferative disorders in patients with inflammatory bowel disease

BACKGROUND: It remains to be shown whether inflammatory bowel disease (IBD) is associated with an increased risk of primary intestinal lymphoproliferative disorders (PILD). We assessed this risk in the CESAME French nationwide prospective observational cohort. METHODS: In all, 680 gastroenterologists enrolled 19,486 patients with IBD (Crohn's disease in 60.3%) from May 2004 to June 2005. Follow-up ended on 31 December 2007. Available biopsy samples and surgical specimens from patients with PILD (n = 14) were centralized for review. The reference incidence of PILD in the general population was obtained from the C?te d'Or registry and was used as a comparator to assess the standardized incidence ratio (SIR). The influence of thiopurine exposure was explored in a nested case-control study. RESULTS: In the CESAME population the crude incidence of PILD was 0.12/1000 patient-years, with a corresponding SIR of 17.51 (95% confidence interval [CI], 6.43-38.11; P < 0.0001). The risk was highest in patients exposed to thiopurines (SIR 49.52, 95% CI 13.49-126.8; P < 0.0001), while it did not reach statistical significance in patients na?ve to thiopurines (SIR 4.83, 95% CI, 0.12-26.91; P = 0.37). The odds ratio associated with ongoing thiopurine exposure (vs. na?ve) was 2.97 (95% CI, 0.30-infinity; P = 0.38). All 14 cases of PILD were non-Hodgkin's B-cell LD, 78.6% occurred in males, 85.7% arose in IBD lesions, and 45.5% were Epstein-Barr virus-positive. Eleven cases occurred in patients with Crohn's disease. Mean (SD) age at PILD diagnosis was 55.1 (5.6) years and the median time since IBD onset was 8.0 years (interquartile range, 3.0-15.8). CONCLUSIONS: Patients with IBD have an increased risk of developing PILD. (Inflamm Bowel Dis 2012;).     

Outpatient penicillin use after negative skin testing and drug challenge in a pediatric population

The practice of elective penicillin skin testing could be compromised by the fact that patients, their parents, or their physicians remain reluctant to reuse penicillin-class antibiotics (PCAs) despite a negative evaluation by an allergist. This study addresses reuse of PCAs in a pediatric population after negative penicillin skin testing and drug challenge and factors associated with its reluctance. All children evaluated for a history of penicillin allergy at the CHU Sainte-Justine Allergy Clinic between January 1998 and June 2000 with negative skin testing and drug challenge were included in the study. A telephone survey was conducted between May and October 2002 to assess the perception of the initial reaction by the parents, subsequent use of antibiotics, and antibiotic-related adverse reactions. Among the 200 children selected, parents of 170 (85%) children completed the survey. Since the allergist evaluation, 130 (76%) children had received antibiotics. PCA was used in 59 (45%) children. Parents of 24 (18%) children refused PCAs because they still feared an adverse reaction. They were more likely to have been very frightened by their child's allergic reaction than other parents whose children had used PCAs (p = 0.008). Although elective penicillin skin testing is useful and safe in the pediatric population, a significant proportion of parents still refuse PCAs even though they are needed. Identification of parents that were very frightened by their children's allergic reactions and additional reassurance could improve this situation.
