Serum zinc levels and efficacy of zinc treatment in acne vulgaris: A systematic review and meta-analysis.

Oral and topical zinc have been used for the treatment of acne, but there is a lack of definitive evidence for their efficacy. (a) To determine if mean serum zinc levels differ between acne patients and controls and (b) to determine the efficacy of zinc preparations in the treatment of acne. A systematic review and meta-analysis was performed according to recommended PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-Analyses] guidelines.

Tolerability and effectiveness of sofosbuvir and simeprevir in the post-transplant setting: systematic review and meta-analysis.

Background: Outcome data on simeprevir and sofosbuvir (SMV+SOF) in patients with liver transplantation (LT) with hepatitis C virus genotype 1 (HCV-1) are limited with individual studies having a small sample size and limited SVR12 (sustained virological response) data. Our goal was to perform a meta-analysis to study the outcome of SMV+SOF±ribavirin (RBV) in recipients with LT.

Methods: In April 2015, we conducted a literature search for 'simeprevir' in MEDLINE/EMBASE and five major liver meetings.

Lower response to simeprevir and sofosbuvir in HCV genotype 1 in routine practice compared with clinical trials.

Background: High sustained virological response at 12 weeks after end of treatment (SVR12) with 12 weeks of simeprevir and sofosbuvir±ribavirin (SMV+SOF±RBV) has been demonstrated in hepatitis C virus genotype 1 (HCV-1) but is based on limited data. Therefore, we performed a meta-analysis of available data evaluating the effectiveness of SMV+SOF±RBV in HCV-1.

Methods: We performed a comprehensive literature search in June 2015 to identify randomised controlled trials (RCTs) and observational studies of HCV-1 patients treated with 12 weeks of SMV+SOF±RBV.

Re-treatment of patients with chronic hepatitis C virus genotype 4 infection with pegylated interferon and ribavirin: a meta-analysis.

Background: An estimated 170 million people worldwide are infected with hepatitis C virus (HCV). HCV genotype 4 (HCV-4)-the most prevalent hepatitis C strain in the Middle East and Africa-is difficult to treat, with an estimated sustained virological response (SVR) of 53% when using pegylated interferon and ribavirin (P/R) in treatment-naïve patients with HCV-4 infection. In regions where access to direct-acting antivirals is limited, re-treatment of patients who failed therapy with another course of P/R may be an option if the success rate is acceptable.

Sustained virological response and its treatment predictors in hepatitis C virus genotype 4 compared to genotypes 1, 2, and 3: a meta-analysis.

Background: Pegylated interferon and ribavirin (PEG-IFN+RBV) may be more cost-effective than direct-acting antivirals in resource-limited settings. Current literature suggests sustained virological response (SVR) in hepatitis C virus genotype 4 (HCV-4) is similar to genotype 1 (HCV-1), but worse than 2 and 3 (HCV-2/3). However, few studies have compared treatment response between these groups and these have been limited by small sample sizes with heterogeneous designs.

Treatment of Acute Hepatitis C Infection with Pegylated Interferon and Ribavirin in Patients Coinfected with Human Immunodeficiency Virus: A Systematic Review and Meta-Analysis.

Background/aims: Of the 35 million human immunodeficiency virus (HIV)-positive patients worldwide, 10-40% are coinfected with chronic hepatitis C virus (HCV). Compared to HCV-monoinfected patients, those coinfected experience decreased spontaneous HCV clearance, accelerated liver fibrosis, and a decreased response to anti-HCV therapy. We conducted a meta-analysis to estimate the efficacy of treating acute HCV in HIV-positive patients with peginterferon and ribavirin combination therapy.

Meta-analysis of patients with hepatitis C virus genotype 6: 48 weeks with pegylated interferon and ribavirin is superior to 24 weeks.

Background: Hepatitis C virus genotype 6 (HCV-6) is common in patients from Southeast Asia and the surrounding regions. Optimal treatment duration for HCV-6 is unknown given the inconclusive evidence from studies with varying methodologies and small sample sizes.

Methods: A literature search for 'genotype 6' in MEDLINE and EMBASE in October 2013 produced 161 and 251 articles, respectively.

Sustained virologic response to standard interferon or pegylated interferon and ribavirin in patients with hepatitis C virus genotype 5: systematic review and meta-analysis of ten studies and 423 patients.

Background: Interferon (IFN)-free therapy has vastly improved therapeutic options for those with hepatitis C virus infection (HCV). However, the lack of data and the expense limit its use for lesser known genotypes such as HCV-5, especially in countries with financial limitations. Previous reports estimate sustained virologic response (SVR) rates in HCV-5 to be ~40-70%.

Meta-analysis: superior treatment response in Asian patients with hepatitis C virus genotype 6 versus genotype 1 with pegylated interferon and ribavirin.

Objective: Our goal was to systematically and quantitatively assess treatment response between Asian patients with hepatitis C virus genotype 6 (HCV-6) and hepatitis C virus genotype 1 (HCV-1) treated for 48 weeks with pegylated interferon and ribavirin.

Methods: We performed a literature search in MEDLINE and EMBASE for 'genotype 6' in August 2013. Additional abstracts from major international scientific conferences from 2012 to 2013 were reviewed.

Crusted scabies of the scalp in a patient with systemic lupus erythematosus.

Background: Crusted scabies is a severe, hyperkeratotic, psoriasiform disorder associated with immune suppression. Affected individuals typically present with crusted hyperkeratotic lesions in a variety of locations. This condition can lead to severe complications: institutional outbreaks and secondary bacterial infections associated with sepsis and high mortality.

Meta-analysis: influence of host and viral factors in patients with chronic hepatitis C genotype 4 treated with pegylated interferon and ribavirin.

The burden of hepatitis C virus genotype 4 (HCV-4) is high in Africa and East Mediterranean countries. Previous reports estimate sustained virologic response (SVR) rates in HCV-4 to be ∼20-70%. However, many of these studies are limited by different study designs and small sample sizes.

Extensive pulmonary involvement with raltegravir-induced DRESS syndrome in a postpartum woman with HIV.

An 18-year-old postpartum woman with HIV, on lamivudine-zidovudine, lopinavir-ritonavir and raltegravir, presented with a 1-week history of rash and fevers. Initially admitted to obstetrics and gynaecology service for treatment of possible endometritis, she was transferred to the HIV medicine service for high fever, respiratory distress, hypotension and tachycardia. On admission, she was febrile (102°F) with findings of cervical and submandibular lymphadenopathy, diffuse morbilliform rash, generalised pruritus, facial oedema, and oedematous hands and feet.
