Meeting the WHO 90% target: antiretroviral treatment efficacy in Poland is associated with baseline clinical patient characteristics.

INTRODUCTION: Modern combined antiretroviral therapies (cART) allow to effectively suppress HIV-1 viral load, with the 90% virologic success rate, meeting the WHO target in most clinical settings. The aim of this study was to analyse antiretroviral treatment efficacy in Poland and to identify variables associated with virologic suppression. M: ethods Cross-sectional data on 5152 (56.92% of the countrywide treated at the time-point of analysis) patients on cART for more than six months with at least one HIV-RNA measurement in 2016 were collected from 14 Polish centres. Patients' characteristics and treatment type-based outcomes were analysed for the virologic suppression thresholds of <50 and <200 HIV-RNA copies/ml. CART was categorized into two nucleos(t)ide (2NRTI) plus non-nucleoside reverse transcriptase (NNRTI) inhibitors, 2NRTI plus protease (PI) inhibitor, 2NRTI plus integrase (InI) inhibitor, nucleos(t)ide sparing PI/r+InI and three drug class regimens. For statistics Chi-square and U-Mann Whitney tests and adjusted multivariate logistic regression models were used. RESULTS: Virologic suppression rates of <50 copies/mL were observed in 4672 (90.68%) and <200 copies/mL in 4934 (95.77%) individuals. In univariate analyses, for the suppression threshold <50 copies/mL higher efficacy was noted for 2NRTI+NNRTI-based combinations (94.73%) compared to 2NRTI+PI (89.93%), 2NRTI+InI (90.61%), nucleos(t)ide sparing PI/r+InI (82.02%) and three drug class regimens (74.49%) (p < 0.0001), with less pronounced but significant differences for the threshold of 200 copies/mL [2NRTI+NNRTI-97.61%, 2NRTI+PI-95.27%, 2NRTI+InI-96.61%, PI/r+InI- 95.51% and 86.22% for three drug class cART) (p < 0.0001). However, in multivariate model, virologic efficacy for viral load <50 copies/mL was similar across treatment groups with significant influence by history of AIDS [OR:1.48 (95%CI:1.01-2.17) if AIDS diagnosed, p = 0.046], viral load < 5 log copies/mL at care entry [OR:1.47 (95%CI:1.08-2.01), p = 0.016], baseline lymphocyte CD4 count ≥200 cells/µL [OR:1.72 (95%CI:1.04-2.78), p = 0.034] and negative HCV serology [OR:1.97 (95%CI:1.29-2.94), p = 0.002]. For viral load threshold <200 copies/mL higher likelihood of virologic success was only associated with baseline lymphocyte CD4 count ≥200 cells/µL [OR:2.08 (95%CI:1.01-4.35), p = 0.049] and negative HCV status [OR:2.84 (95%CI:1.52-5.26), p = 0.001]. CONCLUSIONS: Proportion of virologically suppressed patients is in line with WHO treatment target confirming successful application of antiretroviral treatment strategy in Poland. Virological suppression rates depend on baseline patient characteristics, which should guide individualized antiretroviral tre0atment decisions.

Chronic hepatitis B monitoring and treatment patterns in five European countries with different access and reimbursement policies.

BACKGROUND: In Europe, health-care policies are determined at a national level and differ between countries. This analysis from a prospective, longitudinal, non-interventional study aimed to describe patterns in the clinical monitoring and treatment of chronic hepatitis B (CHB) in five European countries. METHODS: Country-specific cohorts of adult patients with compensated CHB managed in clinics in Germany, France, Poland, Romania and Turkey were followed for up to 2 years between March 2008 and December 2010. RESULTS: A total of 1,267 patients were included. Baseline age and gender distribution were similar across countries for patients who were treated (n=567) and untreated (n=700) at baseline. Most treated patients were receiving monotherapy at baseline, most frequently with entecavir or tenofovir in Germany, France and Turkey, and with lamivudine in Poland and Romania. Use of pegylated interferon was more frequent in Poland and Romania than in other countries. In Romania monotherapy with entecavir increased after it became reimbursed in 2008. Hospitalizations during follow-up were more frequent in Romania (1.45 hospital days/patient-year) and Poland (1.81 days/patient-year) than in Turkey, France and Germany (0.00, 0.05 and 0.10 days/patient-year, respectively); clinic visits were more frequent in Poland (3.20 versus 0.30-1.78 visits/patient-year across other countries). CONCLUSIONS: These results illustrate country-specific patterns in the management of CHB patients across Europe. Observed monitoring patterns, hospitalization rates and other health-care utilization may be related to cost and reimbursement issues; however, further study in individual countries would be required to confirm these (post hoc) observations.

Non-interventional study AI463-12 of real-world chronic HBV infection management--baseline characteristics and treatment patterns of Polish patients kohort.

AIM: This longitudinal non-interventional study aims to describe the demographics data disease characteristics and clinical management of a cross-sectional CHB patient population in Poland treated in regional medical centers. MATERIAL AND METHODS: [corrected] Between March 2008 and December 2010 we observed patients with HBV related liver disease from 5 medical centers in Poland, both sexes, > 18 years old. At baseline, we used a case report form to extract data from patient charts, comprising: sociodemographic data; disease characteristics, HBeAg/ antiHBeAg status, genotype HBV; co-morbidities; viral load, liver biopsy and ALT levels in previous 12 months; treatment history in previous 12 months; current CHB treatment; changes in disease characteristics and CHB management; time from diagnosis to the therapy and resource utilization and any reasons for termination of follow-up. Written informed consent was obtained from all participants RESULTS: The analysis population included 253 patients (94 treated and 159 non-treated at baseline) mostly male (69.1 vs. 56.6). Patients in treated group compared with untreated group were: significantly older (mean 42.6 vs. 37.5 years respectively, p < 0.001), observed longer since diagnosis(3.9 vs.2.9 years), with higher rate of HBeAg(+)(42.6% vs.5.1%), lower ALT activity, and higher VL HBV DNA PCR. Of the 53% of treated patients, the most frequently prescribed anti-HBV drugs were: Lamivudine (53%), Entecavir (23.7%), Pegylated IFN-alfa2a (23.7%), Adefovir (11.1%). During 24 months of follow-up in treated group 13(36.1%) patients underwent a treatment switch to another nucleosi(-ti)de analogue, in one (2.8%) patient another analogue was added, and in 25 (69.4%)patients the therapy was stopped. The proportion of all patients treated with monotherapy at the end of follow-up was 99.4%, unfortunately mostly with Lamivudine-49.3%. SUMMARY: 1. Despite the several methodological limitations usually associated with this type of observation, the collected data does characterize the demographics of polish patients chronically infected with HBV well, provides some insights into the determinants of treatment initiation and the clinical management of patients in real-word settings. 2. These results indicate that in clinical practice in 5 medical non-academic centers in Poland, European guidelines regarding the qualification to HBV treatment were followed, but there were discrepancies between the initial treatment decisions in real-life current clinical practice and guideline recommendations

[The program of early detection of HCV infection]. / Program wczesnego wykrywania zakazenia HCV.

UNLABELLED: All over the world there are over 170 million people with HCV infection and in Poland--about 500-730 thousands. Early detection of HCV infection is important for obtaining better results in treatment of chronic hepatitis C. AIM OF STUDY: Detection in Opolszczyzna people infected HCV, with risk factors of chronic hepatitis C, but not diagnosed before. METHODS: In year 2006 there were tested 143 persons for presence of HCV antibodies and level of ALT activity. Information about program of early detection of HCV infection was in local radio and newspaper. RESULTS: Among 143 tested persons 98 (68,5%) were women and 45 (31,5%)--men. Three of male patients (2,09%) had HCV antibodies and elevated ALT activity. Then they were further diagnosed and all of them had present HCV RNA in blood samples. DISCUSSION AND COCLUSIONS: Changing criteria of selection for such programs should improve percentage of detection of HCV infected people and then it would be beneficial and advantageous from economic but also social point of view.

[Case of typhoid fever in 43 old male]. / Zachorowanie na dur brzuszny 43-letniego mezczyzny.

The disease of 43 years old man, who was being taken in internal ward to diagnosis because of fever, was presented. In bacteriological culture Salmonella Typhi were kept. For reason the isolation was impossible on internal department, patient was conveyed to contagious department. As a result of carried out epidemiological inquiry, it turned out the man's infectious was coused by permanent carrier of typhoid fever.

[Could Legionella pneumophila infection cause bronchial hyperreactivity]. / Czy przyczyna nadreaktywnosci oskrzeli u dzieci moglo byc zakazenie Legionella pneumophila.

11 children with bronchial hyperreactivity were tested for Legionella pneumophila serotype 1 and 2-14, including 3 girls, who were treated a year before because of atypical pneumonia, probably caused by Legionella pneumophila, 2 brothers of the girls and 6 children from a different village as well as 5 adults--parents of the girls. In all of them a significant level of antibodies against Legionella pneumophila serotype 2-14 was detected with indirect immunofluorescence. One of previously treated girls presented with increased level of IgG antibodies (ELISA), the remaining two had increased levels of IgA against Legionella pneumophila serotype 1. Other patients in the group presented no IgM, IgA or IgG against Legionella pneumophila serotype 1. Patients with bronchial hypersensitivity received clarithromycin and inhalation steroids with good clinical effect.
