Suboptimal MMR Vaccination Coverages-A Constant Challenge for Measles Elimination in Romania.

Measles is targeted for elimination since 2001, with a significant reduction in cases recorded worldwide, but outbreaks occur periodically due to immunization gaps. This study analyzes the evolution of vaccination coverage rates (VCRs) in Romania, a EU country with large measles epidemics during the last two decades, including an ongoing outbreak in 2023. Vaccination against measles has been part of the National Immunization Program since 1979, initially as a single dose, and from 1994 onwards it has had two doses.

HIV-HBV Coinfection-Current Challenges for Virologic Monitoring.

HIV-HBV coinfected patients have higher rates of liver-related morbidity, hospitalizations, and mortality compared to HBV or HIV mono-infected ones. Clinical studies have shown an accelerated progression of liver fibrosis and an increased incidence of HCC, resulting from the combined action of HBV replication, immune-mediated hepatocytolysis, and HIV-induced immunosuppression and immunosenescence. Antiviral therapy based on dually active antiretrovirals is highly efficient, but late initiation, global disparities in accessibility, suboptimal regimens, and adherence issues may limit its impact on the development of end-stage liver disease.

HIV transmission clusters among injecting drug users in Romania.

Unlabelled: Injection drug use is increasingly an important route of HIV transmission in Romania (from 1.5% of the newly diagnosed cases prior to 2010 to 31% in 2013). In this study we investigated the viral characteristics and relationships in newly HIV infected persons who inject drugs in Bucharest, Romania.

HCV non-1b genotypes in injecting drug users from Romania.

Introduction: Chronic hepatitis C cases diagnosed in Romania were mostly related to unsafe parenteral treatments and blood transfusions; HCV genotype 1b was prevalent. During the last decade, an increasing number of HCV infections was reported among people who inject drugs (PWID). The aim of the current study was to test if this epidemiological shift triggered a diversification of the circulating viral strains.

Injecting drug use: A vector for the introduction of new hepatitis C virus genotypes.

Hepatitis C virus (HCV) genotypes' monitoring allows real-time insight into the dynamic changes that occur in the global epidemiological picture of HCV infection. Intravenous drug use is currently the primary driver for HCV transmission in developed and developing countries. The distribution of HCV genotypes/subtypes differs significantly between people who inject drugs (PWID) and the general population.

ROMANIAN SCIENTISTS IN THE NOMINATION DATABASE FOR THE NOBEL PRIZE IN PHYSIOLOGY OR MEDICINE, 1901-1951.

Nobelprize.org site is the most reliable and complete resource of information on the Nobel Prize and the Nobel Laureates. The nomination database for Physiology or Medicine, 1901-1951, offers exciting facts about the Romanian Schools of Medicine from Bucharest, Iaşi and Cluj.

Influence of Staphylococcus aureus attachment to the herpes simplex virus infected cells.

The purpose of this study was to investigate the response of HeLa cells to the interaction with inactivated Staphylococcus aureus cells and live challenge with herpes simplex virus (HSV).The results of this study are indicating that the interaction between the HeLa cells and S. aureus inactivated whole cells could modulate the host cell apoptosis and cytokine production, and therefore, influence the progression of HSV infection.

The effectiveness of cytological rescreening in the reduction of false negative/positive Pap reports.

Background: Cytological investigation of the cervix has proven to be a valuable tool in the early detection of cervical cancer; however, the high incidence of false negative or false positive smear reports is an important drawback.

Objectives: To investigate retrospectively the value of partial rescreening methods as tools for improving the sensitivity and specificity of Pap test routine screening.

Methods: Out of a total of 4664 cervical samples examined by Pap test, 20% were randomly selected and rescreened with a more detailed examining protocol by the same cytologist; in addition, targeted rescreening of all samples with severe lesions was carried out.

Investigation of Th1/Th2 cytokine profiles in patients with laryngo-pharyngeal, HPV-positive cancers.

The aim of this study was to reveal the relationships between the features of the primary tumour, the degree of tumour stage, the presence of human papillomaviruses (HPV) in blood and the severity of Th1/Th2 serum cytokine imbalance in patients with laryngo-pharyngeal cancer. The study was performed on 50 patients (47 men and 3 women), with age ranging from 40 to 83 years (the mean of the patients' ages was 58.4 ± 9.

New interferons in the treatment of chronic hepatitis C.

The current standard therapy for chronic HCV infection is a combination of pegylated-interferon (PEG-IFN) and weight-based ribavirin, administered for 24-48 weeks, according to the viral genotype. Although the weekly administration of pegylated interferons provides superior antiviral efficacy over standard interferon alpha, the rate of sustained virological response rarely overpasses 50% in patients infected with HCV genotypes 1 and 4. Consequently, multiple clinical trials with congeners of interferon (consensus interferon, interferon lambda, albinterferon, and controlled-release interferons) are ongoing.

Tracking down of laryngo-pharyngeal metastasis.

Background: In Romania, the most optimistic statistics give a 5 years survival rate in approximately 33% of laryngo-pharyngeal cancer patients. Considering that a cell carrying the viral DNA is originating from primary tumor, we have tested whether HPV DNA could be detected in the blood cell of patients with laryngeal cancer as a marker of disease progression and metastases.

Methods: The study was performed on 85 patients (59 +/- 8.

Influence of social changes on the evolution of HIV infection in Romania.

The Romanian HIV epidemic started and evolved as a paediatric one, accounting for more than a quarter of the total European juvenile AIDS cases. In response to this major AIDS outbreak, emphasis was placed on the patient's treatment, by implementation of a free, universal access program of Highly Active AntiRetroviral Therapy. This approach has been highly successful, and has greatly increased the rate of survival in infected children.

High prevalence of hepatitis B virus markers in Romanian adolescents with human immunodeficiency virus infection.

Background: We evaluated the frequency of hepatitis coinfection in Romanian adolescents who were diagnosed with human immunodeficiency virus (HIV) infection prior to 1995.

Methods: One hundred sixty-one adolescents (13-18 years of age) with symptomatic HIV infection, but without signs of hepatic dysfunction, and 356 age-matched, HIV-uninfected controls underwent laboratory testing for markers of parenterally acquired hepatitis virus infection.

Results: Seventy-eight percent of HIV-infected adolescents had markers of past or present hepatitis B virus (HBV) infection, as compared with 32% of controls ( P = .

Alternatives to HIV-RNA and CD4 count to monitor HIV disease progression: a prospective cohort study in Romania.

Little evidence exists on how to efficiently and effectively monitor HIV-disease progression in developing countries. Better understanding regarding cost-effective tests may help to resolve questions regarding treatment. A prospective cohort study was conducted with a 1-year follow-up period.

Cloning and expression of the L1 major capsid protein of the human papillomavirus 18 in murine cells.

Human papillomavirus (HPV) type 18 is strongly associated with the development of cervical cancer. Studies of a model system with animal papillomaviruses have demonstrated the importance of neutralizing antibodies in preventing papillomavirus-associated disease. The immune response to HPV is poorly understood, and there are non- standardized serological assays to identify HPV infections.
