Prevalence of harassment and discrimination among residents in three training hospitals in Saudi Arabia.

BACKGROUND AND OBJECTIVES: Multiple surveys of medical residents have shown a high incidence of harassment and discrimination in academic health centers. Harassment has a negative effects on residents' health and on their ability to function. No previous study has documented the prevalence of harassment and discrimination among residents in Saudi Arabia. We aimed in this study to assess the prevalence of harassment and discrimination among residents at a tertiary care academic hospitals in Saudi Arabia. DESIGN AND SETTING: Cross-sectional survey conducted at National Guard Hospitals in Riyadh, Jeddah and Al-Ahsa'a from 27 July to 20 August 2010. SUBJECTS AND METHODS: The survey included questions on the prevalence of harassment of different types, inlcuding verbal, academic, physical and sexual harassment, as well as discrimination on the basis of gender, region of origin or physical appearance. RESULTS: Of 380 residents, 213 (56%) returned a completed questionnaire (123 male, 57.8%). At least one of type of harassment and discrimination was reported by 83.6% of respondents. The most frequently reported forms were verbal harassment and gender discrimination (61.5% and 58.3%, respectively). Sexual harassment was commonly reported (19.3%) and was experienced significantly more often by female residents than by male residents (P=.0061). CONCLUSION: Harassment and discrimination of Saudi residents is common with more than three-quarters reporting having had such an experience. Identification of the risk factors is a necessary first step in clarifying this issue and could be used when planning strategies for prevention.

Safety and efficacy of peginterferon-α2a plus ribavirin treatment in renal transplant recipients with chronic hepatitis C.

BACKGROUND & AIMS: Interferon (IFN)-based therapy in chronic hepatitis C virus (HCV)-infected renal transplant (RT) recipients has been associated with a high risk of acute allograft rejection (AAR) and poor efficacy. We assessed the safety and efficacy of PegIFNα-2a and ribavirin (RBV) combination therapy in HCV-infected RT recipients. METHODS: Thirty-two adult RT recipients of >12-month duration, infected with HCV genotypes 1 (62.5%) and 4 (37.5%), and significant fibrosis (Metavir ≥ F2) were recruited in an open-label trial with PegIFNα-2a 135-180 µg/week, plus RBV 200-1200 mg/day for 48 weeks, based on the estimated glomerular filtration rate. Safety assessments were performed weekly for 4 weeks, 2-weekly for 8 weeks, and 6-weekly for 36 weeks. Study end points were sustained virologic response (SVR) or development of AAR. Allograft biopsies were performed for 20% increase in creatinine from pretreatment levels, or optionally at week 12 on surveillance protocol. Renal safety was compared with matched untreated historical controls (n=31). RESULTS: None of the treated patients showed AAR when biopsied for raised creatinine (12.5%) or during surveillance (37.5%), with incremental and sustained creatinine increases occurring in 6.3% of treated patients and 16.1% of untreated controls (p=0.148), by week 72 assessment. Mean pretreatment and end-of-assessment creatinine in treated patients remained similar (106.8 ± 32.0 vs. 113.4 ± 62.8, respectively; p=0.140), while levels increased significantly in the controls (106.6 ± 35.6 vs. 142.5 ± 93.0, respectively; p=0.013). Rapid, early virologic response (EVR) and SVR occurred in 12.5%, 56.3%, and 37.5% of cases, respectively. SVR was similar in both genotypes (p=1.000). PegIFN and RBV dose reductions were required in 34.4% and 78.1%, respectively; discontinuation was required in 12.5%. Binary logistic regression identified only EVR (OR, 20.4; 95% CI: 2.2-192.6; p=0.008) as an independent predictor of SVR. CONCLUSIONS: PegIFN/RBV therapy is not associated with AAR in RT recipients at low risk for rejection but has modest efficacy in the treatment of HCV.

Updated thresholds for alanine aminotransferase do not exclude significant histological disease in chronic hepatitis C.

BACKGROUND AND AIM: Histological changes in hepatitis C virus (HCV)-infected patients with persistently normal alanine aminotransferase (PNALT) have not been evaluated for updated upper limits of normal (ULN; ≤ 19/30 U/L for females/males). We assessed significant fibrosis (≥ F2, METAVIR) in patients with PNALT and persistently elevated alanine aminotransferase (PEALT). PATIENTS AND METHODS: Nine hundred and twenty consecutive, unselected HCV patients were stratified into four groups: Group I: (n = 124) PNALT within the updated ULN [0.5 × ULN (corresponding to ≤ 19 U/L) for females; 0.75 × ULN (corresponding to ≤ 30 U/L) for males]; Group II (n = 173): PNALT ≤ 1 × ULN but greater than Group I; Group III (n = 313): PEALT 1-2 × ULN; and Group IV (n = 310): PEALT > 2 × ULN. PNALT was defined as ≥ 3 determinations within the normal range over ≥ 6 months. RESULTS: Advanced ≥ F3 and ≥ F2 fibrosis increased incrementally across Groups I; II; III; and IV: 24.2 and 45.2%; 25.4 and 56.1%; 36.1 and 64.2%; and 50 and 77.1% respectively (P<0.0001 for both). Multivariable logistic regression analysis identified age [odds ratio (OR), 1.05; 95% confidence intervals (CI): 1.02-1.08; P<0.0001], alanine aminotransferase (ALT) groups (OR 1.38; 95% CI: 1.03-1.83; P = 0.030), presence of moderate-severe steatosis (OR 2.70; 95% CI: 1.19-6.15; P = 0.018) and ≥ A2 necroinflammation (OR 17.9; 95% CI: 8.88-36.20; P < 0.0001) as independent predictors of ≥ F2 fibrosis. Updated ULN for ALT were better at excluding ≥ F2 fibrosis compared with traditional ULN (90.6 vs. 74.2%, P = 0.0041) but less specific (20.8 vs. 44%, P = 0.0007) with similar positive/negative predictive values. CONCLUSIONS: HCV patients with 'updated' normal ALT have the lowest prevalence of significant fibrosis, although utilizing these levels without resorting to biopsy would miss significant fibrosis in almost one-half of such patients.
