TL;DR: Acute HCV is an uncommon disease to diagnose; it has favorable response to therapy if initiated early after a strict surveillance of patients for 8-16 weeks.
Abstract: Objective: To determine the frequency of acute HCV infection after needle stick injury and its treatment outcome. Methodology: Patients with HCV positive needle stick injury and reporting within 72 hours of incident were selected. Co-infections with HBV, HDV, HIV, hematological disorders and depression were excluded. Anti-HCV was done at presentation and those testing positive were excluded. HCV RNA was done after two weeks or anti-HCV after six weeks of incident. Those testing positive were kept under observation for 16 weeks for spontaneous resolution. After this period HCV RNA and Genotype were done and therapy with Peg-interferon was started. Rapid, early and sustained virological responses were checked. Results: Two hundred eight patients with HCV positive needle stick injury were selected, 10 (4.8%) developed acute HCV infection out of them one (10%) had spontaneous recovery during the observation period of 16 weeks. seven (77.8%) achieved rapid virological response and eight (88.9%) achieved sustained virological response. Conclusions: Acute HCV is an uncommon disease to diagnose; it has favorable response to therapy if initiated early after a strict surveillance of patients for 8-16 weeks.

TL;DR: To characterize hepatitis C virus (HCV) epidemiology in Pakistan and estimate the pooled mean HCV antibody prevalence in different risk populations, all available records of HCV incidence and/or prevalence from 1989 to 2016 were systematically reviewed.
Abstract: To characterize hepatitis C virus (HCV) epidemiology in Pakistan and estimate the pooled mean HCV antibody prevalence in different risk populations, we systematically reviewed all available records of HCV incidence and/or prevalence from 1989 to 2016, as informed by the Cochrane Collaboration Handbook. This systematic review was reported following the PRISMA guidelines. Populations were classified into six categories based on the risk of exposure to HCV infection. Meta-analyses were performed using DerSimonian and Laird random-effects models with inverse variance weighting. The search identified one HCV incidence study and 341 prevalence measures/strata. Meta-analyses estimated the pooled mean HCV prevalence at 6.2% among the general population, 34.5% among high-risk clinical populations, 12.8% among populations at intermediate risk, 16.9% among special clinical populations, 55.9% among populations with liver-related conditions and 53.6% among people who inject drugs. Most reported risk factors in analytical epidemiologic studies related to healthcare procedures. Pakistan is enduring an HCV epidemic of historical proportions—one in every 20 Pakistanis is infected. HCV plays a major role in liver disease burden in this country, and HCV prevalence is high in all-risk populations. Most transmission appears to be driven by healthcare procedures. HCV treatment and prevention must become a national priority.

TL;DR: Needle stick injury is the most important occupational health hazard in nurses with alarmingly high rates and screening of nurses after needle stick injury and promotion of safety measures against it should be greatly encouraged.
Abstract: Background: Needle-stick injury (NSI) is a major occupational health and safety issue faced by healthcare professionals globally. This study was aimed to assess the frequency and factors associated with NSIs in nurses of a tertiary health care facility in Lahore, Pakistan. It also focuses on safety measures adopted by these nurses after a needle stick injury. Methods : This cross-sectional descriptive study was conducted in Ghurki Trust Teaching Hospital, Lahore from October 2009 to January 2010. All nurses have participated in the study with a response rate of 99%. These responses were obtained via a pretested self-administered questionnaire. The data was analysed using SPSS-16. Percentages of the categorical variables were computed and represented in various statistical data presentation forms, for analysis and comparison. Chi-square test was applied as a test of significance with fixing the p value of 0.05 as significant. Results: Out of 77 nurses who participated in our study, only 33 (42%) nurses were aware of the occupational hazards of their profession when they joined nursing. Needle stick injury was reported by 40 (71.9%) of the nurses in last one year. About 17 (31.5%) were injured at the time of recapping the syringe. The availability of needle cutters in the hospital was reported by 75 (97.4%) nurses while only 46 (60%) of them had undertaken a sharp management training course. Approximately 50 (64.9%) nurses failed to use gloves while administering injections. After getting stuck by a contaminated needle 71 (92%) of the nurses cleaned the wound with a spirit swab, 67 (87%) washed the area with soap and water and 58 (75%) applied a readily available bandage. Only 38 (49%) went on to inform the higher officials about a needle stick injury. Fifty-seven (74%) of the nurses were vaccinated against HBV, and 56 (72.2%) of needle stick injured nurses proceeded for HBV screening, while 53 (68.6%) for HCV and 37(48.5%) for HIV. Conclusion: Needle stick injury is the most important occupational health hazard in nurses with alarmingly high rates. Reporting to the concerned authorities, screening of nurses after needle stick injury and promotion of safety measures against it should be greatly encouraged.

TL;DR: Though there is extensive variation in study-specific measures of HCV viremic rate, pooled mean estimates are similar regardless of risk population or subpopulation, country/subregion, HCV antibody prevalence in the background population, or sex.
Abstract: Objectives To estimate hepatitis C virus (HCV) viremic rate, defined as the proportion of HCV chronically infected individuals out of all ever infected individuals, in the Middle East and North Africa (MENA). Methods Sources of data were systematically-gathered and standardized databases of the MENA HCV Epidemiology Synthesis Project. Meta-analyses were conducted using DerSimonian-Laird random-effects models to determine pooled HCV viremic rate by risk population or subpopulation, country/subregion, sex, and study sampling method. Random-effects meta-regressions were conducted to identify predictors of higher viremic rate. Results Analyses were conducted on 178 measures for HCV viremic rate among 19,593 HCV antibody positive individuals. In the MENA region, the overall pooled mean viremic rate was 67.6% (95% CI: 64.9-70.3%). Across risk populations, the pooled mean rate ranged between 57.4% (95% CI: 49.4-65.2%) in people who inject drugs, and 75.5% (95% CI: 61.0-87.6%) in populations with liver-related conditions. Across countries/subregions, the pooled mean rate ranged between 62.1% (95% CI: 50.0-72.7%) and 70.4% (95% CI: 65.5-75.1%). Similar pooled estimates were further observed by risk subpopulation, sex, and sampling method. None of the hypothesized population-level predictors of higher viremic rate were statistically significant. Conclusions Two-thirds of HCV antibody positive individuals in MENA are chronically infected. Though there is extensive variation in study-specific measures of HCV viremic rate, pooled mean estimates are similar regardless of risk population or subpopulation, country/subregion, HCV antibody prevalence in the background population, or sex. HCV viremic rate is a useful indicator to track the progress in (and coverage of) HCV treatment programs towards the set target of HCV elimination by 2030.

TL;DR: Dental practitioners were at high risk of getting Needle Stick Injuries in dental offices because there was lack of practice of universal precautions.
Abstract: Background: Needle stick injury has been identified as the foremost health allied concern and the specialty of dentistry is not an exception. Its incidence can be reduced when a dental practitioner is completely proverbial to the standard cross-infection control measures. This study was intended to assess the knowledge, attitude and practices among the dental practitioners regarding Needle Stick Injuries and associated risk factors. Methods: This survey was carried out in the Oral Surgery Department, Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Karachi. Dental practitioners of different job categories were conveniently approached by the BDS students. They all were provided with a structured and validated, self-administered questionnaire. Descriptive statistics and Chi-square test was applied with 5% level of significance. Results: All 100 (55 females and 45 males) practitioners agreed to participate in the study. Prevalence of Needle Stick Injury observed was 30% with no significant relationship with the demographic characteristics. Seventy-four percent of the participants were aware of the universal guidelines. Majority (88%) of the dental personnel believed that recapping of needles should be performed soon after use and 53% knew about needle-less safety devices. These injuries were experienced by 30% of the respondents, of which just 28% were reported. Conclusion: Dental practitioners were at high risk of getting Needle Stick Injuries in dental offices. Most of them had knowledge about it but there was lack of practice of universal precautions. Keywords: Needle Stick Injury, Blood Borne Diseases, Dental Practitioners, precaution, infection

TL;DR: Early treatment of acute HCV infection with PegIFNα2a and ribavirin for 24 weeks yields a high sustained virological response rate in HIV-infected patients.
Abstract: BACKGROUND Treatment of acute hepatitis C (HCV) in HIV-infected patients has been poorly addressed. OBJECTIVE To evaluate the efficacy and tolerability of a 24 week course of pegylated interferon alfa 2a (PegIFNalpha2a) and ribavirin for the treatment of acute HCV infection in HIV-infected patients. METHODS This was a prospective pilot study of 25 consecutive HIV-infected men with acute HCV infection defined by documented HCV seroconversion to anti-HCV positive antibody and positive qualitative HCV RNA measurement. Patients with detectable HCV RNA (> 50 IU/ml) 12 weeks after diagnosis were offered treatment with PegIFNalpha2a (180 microg/week) and ribavirin (800 mg/day) for 24 weeks. Sustained virological response was defined by a negative qualitative HCV RNA measurement 24 weeks after the end of treatment. RESULTS At baseline, 23 patients were taking HAART, 23 patients had HIV RNA < 200 copies/ml and a median CD4 count of 345 cells/microl. Only one patient, with genotype 3 HCV, had a spontaneous clearance of HCV RNA. Of the remaining 24 patients, four refused anti-HCV therapy, ribavirin was contraindicated in one and 19 initiated anti-HCV therapy. Median time between acute HCV diagnosis and initiation of study treatment was 14 weeks. Of the 14 patients who have achieved the post-treatment follow-up at 24 weeks, 10 had a sustained virological response (71%). Study treatment was well tolerated, with no change in CD4 cell count. CONCLUSION Early treatment of acute HCV infection with PegIFNalpha2a and ribavirin for 24 weeks yields a high sustained virological response rate in HIV-infected patients.

TL;DR: The study underlines the importance of HBV vaccinations and access to HIV-post-exposure prophylaxis for HCWs as well as the use of anti-needlestick devices.
Abstract: Objectives: Our paper measures the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) in patients at the University Hospital of Frankfurt/Main, and correlates the prevalence with risk factors for exposure to and infection of healthcare workers (HCWs). Individual risk assessments were calculated for exposed HCWs. Methods: Survey of patients admitted to a German University Hospital. Markers for HBV, HCV and HIV were studied and evaluated statistically. Data on needlestick injuries (NSIs) among HCWs were correlated with the prevalence of infectious patients. Results: The HBV, HCV and HIV prevalence among patients at the University Hospital were 5.3% (n 5 709/13 358), 5.8% (n 5 1167/20 163) and 4.1% (n 5 552/13 381), respectively. Our results indicate that the prevalence of blood-borne infections in patients was about nine times higher for HBV, � 15 times higher for HCV and � 82 times higher for HIV than in the overall German population. The highest risk of acquiring a blood-borne infection via NSI was found in the department of internal medicine due to increased prevalence of blood-borne pathogens in patients under treatment. Conclusions: While accidental NSIs were most frequent in surgery, the nominal risk of blood-borne virus infection was greatest in the field of internal medicine. The study underlines the importance of HBV vaccinations and access to HIV-post-exposure prophylaxis for HCWs as well as the use of anti-needlestick devices.
