    Abstract Including HIV disease in the differential diagnosis is the responsibility of the treating physician. Unfortunately, despite 35 years passed from the description of the first cases of Acquired Immune Deficiency Syndrome, AIDS testing for HIV is offered sporadically in Poland. The aim of this paper is to present the current recommendations for HIV testing.

    Abstract Approximately 25% of HIV-infected patients are co-infected with HCV. Notably, the burden of HCV infection (e.g., viral persistence, viral load, or HCV-related liver symptoms) is more pronounced in the presence of HIV co-infection. However, to date, the underlying immune mechanisms accounting for accelerated disease progression in HIV/HCV-coinfected individuals have not been described in sufficient detail. We hypothesized that regulatory T cells (Treg) bearing potent immunosuppressive capacities could not only play a substantial role in the pathogenesis of HCV/HIV coinfection but also modulate the response to the standard anti-viral therapy. Materials and Methods: To this end, we studied alterations in frequencies of Treg cells in correlation with other Treg-related and virus-related parameters in both HCV and HCV/HIV-infected patients subjected to standard pegIFN-α/RBV therapy. Results: Notably, we found that pegIFN-α/RBV therapy significantly increased levels of Treg cells in HCV-infected but not in HIV/HCV-coinfected individuals. Furthermore, HIV/HCV-coinfection was demonstrated to inhibit expansion of regulatory T cells during anti-viral treatment; thus, it might probably be responsible for viral persistence and HCV-related liver damage. Conclusions: Therapy with pegIFN-α/RBV demonstrated a significant effect on regulatory T cells in the course of HIV and/or HCV infection indicating a crucial role in the anti-viral immune response.

    Title translation Microbial translocation in HIV infection.
    Abstract Contemporary antiretroviral therapy has significantly improved the prognosis of human immunodeficiency virus (HIV) infected individuals. However, treated individuals manifest increased mortality, compared to general population. This increased mortality seems to be associated with chronic immune activation which persist despite decrease of plasma HIV viremia levels. Recently, translocation of bacterial products from the gastrointestinal tract has been proposed as a major cause of pathological immune activation.

    Abstract Background: Metabolic syndrome (MS) is usually diagnosed based on the presence of abdominal obesity, elevated blood pres-sure (BP), elevated fasting plasma glucose, high serum triglycerides (TG), and low high-density lipoprotein (HDL) cholesterol levels. Whether HIV is associated with a higher prevalence of MS than in the general population remains unclear.
    Aim: The aim of the study was to determine the incidence of MS in the population of HIV-infected adults and its association with clinical, virological, and biochemical features.
    Methods: Two hundred and seventy HIV-infected Caucasian adult patients were enrolled in the study and evaluated based on clinical records in the years 2013-2015.
    Results: Metabolic syndrome was diagnosed in 60 of 270 (22%) patients, 47 (24%) males and 13 (17%) females, mostly (72%) aged above 40 years. The percentage of patients with diagnosed MS in specific age groups in comparison to the general Polish population for females aged < 40 years was 7% vs. 4%, and males in the same age - 18% vs. 9%, for females aged 40-59 years - 47% vs. 24.4%, and males - 33% vs. 28.3%. Particular components of MS in the MS population were found as follows: body mass index > 30 kg/m2 in 29%, waist circumference exceeding 94 cm in men and 80 cm in woman - 87.5%, TG ≥ 150 mg/dL - 82%, HDL cholesterol < 40/50 mg/dL (males/females) - 42%, systolic/diastolic BP ≥ 130 mmHg/≥ 85 mmHg - 83%, and fasting glucose > 100 mg/dL - 42%. In stepwise multivariate logistic regression analysis, age (odds ratio [OR] 1.052, 95% con-fidence interval [CI] 1.018-1.088, p = 0.003) and nadir CD4 < 350 cells/mm3 (OR 3.576, 95% CI 1.035-12.355, p = 0.04) were associated with MS. Patients with MS compared with those without this disorder had low, intermediate, high, and very high cardiovascular risk in 10% vs. 23%, 73% vs. 70%, 7% vs. 5%, and 10% vs. 2%, respectively (p = 0.006).
    Conclusions: Prevalence of MS in the HIV-infected population is higher than in the general Polish population. Age and low nadir CD4 were found to be associated with MS.

    Abstract In the last years the retroviral disease, caused by the human immunodeficiency virus (HIV), turned from an incurable to a chronic disease. This fundamental change happened due to a huge progress in the understanding of the pathogenesis and treatment of this infection. However, one question still remains open: what is the best time to introduce therapy. The CD4 count is the point of reference to start of the treatment in HIV infected patients. Tendency to introduce highly active antiretroviral therapy (HAART) as early as possible has been observed recently. According to the most recent guidelines of the World Health Organization HAART should be started when CD4 reaches < or = 500 cells/microl. The aim of this paper is justification for the early introduction of antiretroviral therapy in patients living with HIV.

    Title translation Delayed HIV disease diagnosis, despite multiple hospitalizations--case report.
    Abstract Prevalence of human immunodeficiency virus (HIV) infection remains very low in Poland and is estimated to be 0.2%. The number of people undergoing HIV-testing is low. Only 10% population was ever tested and the HIV morbidity increases yearly in Poland. The percentage of late diagnoses is high and remains so in recent years. The aim of the current paper was to present a case of female patient, the partner intravenous drug user, who was hospitalized several times due to: aseptic meningitis, delivery, thrombocytopenia and was never offered a HIV testing. The disease was diagnosed at the late stage with CD4 count of 39 cells/microl (13%). Diagnosis of the disease at the advanced stage potentially reduces a chance for successful treatment and is associated with worse prognosis. Routine testing for HIV infection should be widely available in any health care facility and be directed in particular to people with specific indicator conditions or risky behaviors.

    Abstract Background: HIV/HCV co-infection predisposes to accelerated liver damage and increased both liver-related and unrelated morbidity and mortality in patients with HIV infection.
    Objectives: The aim of this study was to evaluate the prevalence of HCV infection, seropositivity, risk factors and genotype distribution among treated HIV positive patients. Furthermore, the occurrence and causes of deaths were analyzed.
    Patients and methods: Adult HIV-1 infected patients, with at least one antiHCV result, treated in one of Polish HIV/AIDS reference centers, participated in this cross-sectional study.
    Results: Four hundred and fifty seven patients with a median age of 38 years (ranged 23 - 72), and predominantly male (76.6%) were enrolled in the study. Anti-HCV antibodies were detected in 325 individuals (71.1%). HCV RNA was detected in 207 of the 233 patients tested (88%). The HCV genotype analysis (n = 193) demonstrated almost equal distribution with slight genotype 1 domination as 37.3%, mainly 1b, followed by genotypes 3 as 32.1% and 4 as 30.6%. No association was found between HCV genotype and route of HIV acquisition. In univariate analysis, higher HCV seropositivity was related to male sex, intravenous drug use (IDU), mode of HIV transmission, history of drug and alcohol abuse and imprisonment. In multivariate analysis, only being injection drug user (P = 0.0001), imprisonment (P = 0.310) and younger age at the HIV diagnosis per each year (P = 0.025) were identified as risk factors for HCV infection. Sixty three deaths were reported; no association was found between HCV seropositivity and death prevalence.
    Conclusions: HIV/HCV co-infection is an important medical problem in North-Eastern Poland. A history of incarceration and younger age at HIV diagnosis were additional to IDU risk factors for HCV seropositivity in this cohort.

    Title translation Serum HCV core antigen concentration in HCV monoinfection and HCV/HIV coinfection.
    Abstract Unlabelled: Currently, in the diagnosis and monitoring of treatment of HCV infection are used molecular biology methods to detect HCV genetic material and which are based on the polymerase chain reaction (PCR). Due to limitations in the application of this method, such as expensiveness and labor intensive, the alternative might be quantification of HCV core antigen (HCVcAg). Aim of the study was an evaluation of HCVcAg concentrations in patients monoinfected with HCV and HCV/HIV coinfected depending on laboratory parameters characterizing HCV and HIV infections, as well as to evaluate the usefulness of HCVcAg concentrations as a predictor of treatment efficacy.
    Materials and methods: The study was conducted in 31 patients including 12 HCV/HIV coinfected and 19 HCV monoinfected enrolled for treatment with pegylated interferon combined with ribavirin. HCVcAg concentrations were analyzed with regard to HCV RNA level, laboratory indicators of liver function and hematology and additionally in HIV infected to HIV RNA level and immune status. During the treatment the prognostic value of HCVcAg concentrations were analyzed before treatment, at 24 hours, as well as 4 and 12 weeks after initiation of therapy for possible prediction of sustained virologic response (SVR).
    Results: Among HCV monoinfected patients significant correlation has been shown between HCVcAg concentrations and HCV RNA levels, that was not a case in HCV/HIV co-infection. Significant HCVcAg reduction was demonstrated in both groups during initial 24 hours of treatment, but there were no significant differences between groups at particular time points. Baseline HCVcAg levels were significantly higher in patients without SVR compared to those who achieved SVR and this trend continued throughout the analyzed treatment period.
    Conclusions: HCVcAg concentration demonstrate correlation with HCV RNA, and its decrease at the beginning of treatment can predict SVR. HIV coinfection does not affect HCVcAg concentration during therapy.
