Abstract
Testing for HIV is critical for early diagnosis of HIV infection, providing long-term good health for the individual and prevention of onward transmission if antiretroviral treatment is initiated early. The main purpose of the 2021 European Guideline on HIV Testing in Genito-Urinary Settings is to provide advice on testing for HIV infection in individuals aged 16 years and older who present to sexually transmitted infection, genito-urinary or dermato-venereology clinics across Europe. The guideline presents the details of best practice and offers practical guidance to clinicians and laboratories to identify and offer HIV testing to appropriate patient groups.

Abstract
OBJECTIVES Pre-exposure prophylaxis (PrEP) for HIV infection is an important intervention for control of the HIV epidemic. The incidence of HIV infection is increasing in the countries of Central and Eastern Europe (CEE). Therefore, we investigated the change in PrEP use in CEE over time. METHODS The Euroguidelines in Central and Eastern Europe (ECEE) Network Group was initiated in February 2016 to compare standards of care for HIV and viral hepatitis infections in CEE. Data on access to PrEP were collected from 23 countries through online surveys in May-June 2017 (76 respondents) and in November 2018-May 2019 (28 respondents). RESULTS About 34.2% of respondents stated that tenofovir/emtricitabine (TDF/FTC) was licensed for use in their country in 2017, and 66.7% that it was licensed for use in 2018 (P = 0.02). PrEP was recommended in national guidelines in 39.5% of responses in 2017 and 40.7% in 2018 (P = 0.378). About 70.7% of respondents were aware of "informal" PrEP use in 2017, while 66.6% were aware of this in 2018 (P = 0.698). In 2018, there were 53 centres offering PreP (the highest numbers in Poland and Romania), whereas six countries had no centres offering PreP. The estimated number of HIV-negative people on PreP in the region was 4500 in 2018. Generic TDF/FTC costs (in Euros) ranged from €10 (Romania) to €256.92 (Slovakia), while brand TDF/FTC costs ranged from €60 (Albania) to €853 (Finland). CONCLUSIONS Although the process of licensing TDF/FTC use for PrEP has improved, this is not yet reflected in the guidelines, nor has there been a reduction in the "informal" use of PrEP. PrEP remains a rarely used preventive method in CEE countries.

Abstract
OBJECTIVES Although outcomes of antiretroviral therapy (ART) have been evaluated in randomized controlled trials, experiences from subpopulations defined by age, CD4 count or viral load (VL) in heterogeneous real-world settings are limited. METHODS The study design was an international multicohort collaboration. Logistic regression was used to compare virological and immunological outcomes at 12 ± 3 months after starting ART with an integrase strand transfer inhibitor (INSTI), contemporary nonnucleoside reverse transcriptase inhibitor (NNRTI) or boosted protease inhibitor (PI/b) with two nucleos(t)ides after 1 January 2012. The composite treatment outcome (cTO) defined success as VL < 200 HIV-1 RNA copies/mL with no regimen change and no AIDS/death events. Immunological success was defined as a CD4 count > 750 cells/μL or a 33% increase where the baseline CD4 count was ≥ 500 cells/μL. Poisson regression compared clinical failures (AIDS/death ≥ 14 days after starting ART). Interactions between ART class and age, CD4 count, and VL were determined for each endpoint. RESULTS Of 5198 ART-naïve persons in the International Cohort Consortium of Infectious Diseases (RESPOND), 45.4% started INSTIs, 26.0% PI/b and 28.7% NNRTIs; 880 (17.4%) were aged > 50 years, 2539 (49.4%) had CD4 counts < 350 cells/μL and 1891 (36.8%) had VL > 100 000 copies/mL. Differences in virological and immunological success and clinical failure among ART classes were similar across age groups (≤ 40, 40-50 and > 50 years), CD4 count categories (≤ 350 vs. > 350 cells/μL) and VL categories at ART initiation (≤ 100 000 vs. > 100 000 copies/mL), with all investigated interactions being nonsignificant (P > 0.05). CONCLUSIONS Differences among ART classes in virological, immunological and clinical outcomes in ART-naïve participants were consistent irrespective of age, immune suppression or VL at ART initiation. While confounding by indication cannot be excluded, this provides reassuring evidence that such subpopulations will equally benefit from contemporary ART.

Abstract
The EuroSIDA study was initiated in 1994 and follows adult people living with HIV (PLHIV) in 100 collaborating clinics across 35 countries covering all European regions, Israel and Argentina. The study aims to study the long-term virological, immunological and clinical outcomes of PLHIV and to monitor temporal changes and regional differences in outcomes across Europe. Annually collected data include basic demographic characteristics, information on AIDS- and non-AIDS-related clinical events, and details about antiretroviral therapy (ART), hepatitis C treatment and other medications, in addition to a range of laboratory values. The summer 2016 data set held data from a total of 23 071 individuals contributing 174 481 person-years of follow-up, while EuroSIDA's unique plasma repository held over 160 000 samples. Over the past 25 years, close to 300 articles have been published in peer-reviewed journals (h-index 52), covering a range of scientific focus areas, including monitoring of clinical and virological outcomes, ART uptake, efficacy and adverse events, the influence of hepatitis virus coinfection, variation in the quality of HIV care and management across settings and regions, and biomarker research. Recognizing that there remain unresolved issues in the clinical care and management of PLHIV in Europe, EuroSIDA was one of the cohorts to found The International Cohort Consortium of Infectious Disease (RESPOND) cohort consortium on infectious diseases in 2017. In celebration of the EuroSIDA study's 25th anniversary, this article aims to summarize key scientific findings and outline current and future scientific focus areas.

Abstract
Transmitted human immunodeficiency virus drug resistance in Europe is stable at around 8%. The impact of baseline mutation patterns on susceptibility to antiretroviral drugs should be addressed using clinical guidelines. The impact on baseline susceptibility is largest for nonnucleoside reverse transcriptase inhibitors. Background. Numerous studies have shown that baseline drug resistance patterns may influence the outcome of antiretroviral therapy. Therefore, guidelines recommend drug resistance testing to guide the choice of initial regimen. In addition to optimizing individual patient management, these baseline resistance data enable transmitted drug resistance (TDR) to be surveyed for public health purposes. The SPREAD program systematically collects data to gain insight into TDR occurring in Europe since 2001. Methods. Demographic, clinical, and virological data from 4140 antiretroviral-naive human immunodeficiency virus (HIV)–infected individuals from 26 countries who were newly diagnosed between 2008 and 2010 were analyzed. Evidence of TDR was defined using the WHO list for surveillance of drug resistance mutations. Prevalence of TDR was assessed over time by comparing the results to SPREAD data from 2002 to 2007. Baseline susceptibility to antiretroviral drugs was predicted using the Stanford HIVdb program version 7.0. Results. The overall prevalence of TDR did not change significantly over time and was 8.3% (95% confidence interval, 7.2%–9.5%) in 2008–2010. The most frequent indicators of TDR were nucleoside reverse transcriptase inhibitor (NRTI) mutations (4.5%), followed by nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.9%) and protease inhibitor mutations (2.0%). Baseline mutations were most predictive of reduced susceptibility to initial NNRTI-based regimens: 4.5% and 6.5% of patient isolates were predicted to have resistance to regimens containing efavirenz or rilpivirine, respectively, independent of current NRTI backbones. Conclusions. Although TDR was highest for NRTIs, the impact of baseline drug resistance patterns on susceptibility was largest for NNRTIs. The prevalence of TDR assessed by epidemiological surveys does not clearly indicate to what degree susceptibility to different drug classes is affected.

Abstract
European guidelines recommend the routine offer of an HIV test in patients with a number of AIDS-defining and non-AIDS conditions believed to share an association with HIV; so called indicator conditions (IC). Adherence with this guidance across Europe is not known. We audited HIV testing behaviour in patients accessing care for a number of ICs. Participating centres reviewed the case notes of either 100 patients or of all consecutive patients in one year, presenting for each of the following ICs: tuberculosis, non-Hodgkins lymphoma, anal and cervical cancer, hepatitis B and C and oesophageal candidiasis. Observed HIV-positive rates were applied by region and IC to estimate the number of HIV diagnoses potentially missed. Outcomes examined were: HIV test rate (% of total patients with IC), HIV test accepted (% of tests performed/% of tests offered) and new HIV diagnosis rate (%). There were 49 audits from 23 centres, representing 7037 patients. The median test rate across audits was 72% (IQR 32–97), lowest in Northern Europe (median 44%, IQR 22–68%) and highest in Eastern Europe (median 99%, IQR 86–100). Uptake of testing was close to 100% in all regions. The median HIV+ rate was 0.9% (IQR 0.0–4.9), with 29 audits (60.4%) having an HIV+ rate >0.1%. After adjustment, there were no differences between regions of Europe in the proportion with >0.1% testing positive (global p = 0.14). A total of 113 patients tested HIV+. Applying the observed rates of testing HIV+ within individual ICs and regions to all persons presenting with an IC suggested that 105 diagnoses were potentially missed. Testing rates in well-established HIV ICs remained low across Europe, despite high prevalence rates, reflecting missed opportunities for earlier HIV diagnosis and care. Significant numbers may have had an opportunity for HIV diagnosis if all persons included in IC audits had been tested.

Abstract
BACKGROUND The combination of tenofovir and efavirenz with either lamivudine or emtricitabine (TELE) has proved to be highly effective in clinical trials for first-line treatment of HIV-1 infection. However, limited data are available on its efficacy in routine clinical practice. METHODS A multicentre cohort study was performed in therapy-naive patients initiating ART with TELE before July 2009. Efficacy was studied using ITT (missing or switch = failure) and on-treatment (OT) analyses. Genotypic susceptibility scores (GSSs) were determined using the Stanford HIVdb algorithm. RESULTS Efficacy analysis of 1608 patients showed virological suppression to <50 copies/mL at 48 weeks in 91.5% (OT) and 70.6% (ITT). Almost a quarter of all patients (22.9%) had discontinued TELE at week 48, mainly due to CNS toxicity. Virological failure within 48 weeks was rarely observed (3.3%, n = 53). In multilevel, multivariate analysis, infection with subtype B (P = 0.011), baseline CD4 count <200 cells/mm³ (P < 0.001), GSS <3 (P = 0.002) and use of lamivudine (P < 0.001) were associated with a higher risk of virological failure. After exclusion of patients using co-formulated compounds, virological failure was still more often observed with lamivudine. Following virological failure, three-quarters of patients switched to a PI-based regimen with GSS <3. After 1 year of second-line therapy, viral load was suppressed to <50 copies/mL in 73.5% (OT). CONCLUSIONS In clinical practice, treatment failure on TELE regimens is relatively frequent due to toxicity. Virological failure is rare and more often observed with lamivudine than with emtricitabine. Following virological failure on TELE, PI-based second-line therapy was often successful despite GSS <3.

Abstract
We assessed hepatitis E virus (HEV) seroprevalence in patients with hepatic disorders as well as in human immunodeficiency virus (HIV)-infected patients and emphasised the issue of possible non-specific anti-HEV seroresponse and need for combining diagnostic methods for hepatitis E diagnosis. Over a two-year period, from March 2011 to February 2013, we determined anti-HEV immunoglobulin M (IgM) and IgG by enzyme immunoassays (EIA; Mikrogen, Germany) in 504 hepatitis patients negative for acute viral hepatitis A-C. Furthermore, 88 samples from randomly selected consecutive HIV-infected patients were also analysed. All EIA reactive samples were additionally tested by line immunoblot assays (LIA; Mikrogen, Germany). HEV nested reverse transcription polymerase chain reaction (RT-PCR) was carried out in 14 anti-HEV IgM LIA-positive patients. Anti-HEV IgM or IgG were detected in 16.9 % of patients by EIA and confirmed by LIA in 10.7 % [95 % confidence interval (CI) 8.3-13.7 %] of hepatitis patients. HEV RNA was detected in five patients. The agreement between EIA and LIA assessed by Cohen's kappa was 0.47 (95 % CI 0.55-0.75) for IgM and 0.83 (95 % CI 0.78-0.93) for IgG. Anti-HEV IgM and IgG seroprevalence in HIV-infected patients was 1.1 %, respectively. Our findings show a rather high HEV seroprevalence in patients with elevated liver enzymes in comparison to HIV-infected patients. Discordant findings by different methods stress the need to combine complementary methods and use a two-tier approach with prudent interpretation of reactive serological results for hepatitis E diagnosis.

Abstract
We provide a summary of the current status of the human immunodeficiency virus (HIV) epidemic, including data on the transmission of drug-resistant virus in the European Region of the WHO. The review was conducted by searching the reports of the European Centre for Disease Prevention and Control and the United Nations General Assembly Special Session country reports to identify the number of HIV cases reported in 2002-2011, the number of HIV tests performed, and the results of the most recent HIV surveys in at-risk groups. In the West, a 5-year linear trend analysis suggests an increase in the number of reported HIV cases in Belgium, Greece, and Iceland, and a decline in The Netherlands, Ireland, Portugal, Switzerland, and the UK. In the Centre, the number of reported cases increased in Bulgaria and Turkey, and in the East, the number of reported cases increased in Armenia, Georgia, and Ukraine. Estonia and Latvia reported a significant downward trend. HIV transmission in men who have sex with men (MSM) and heterosexual transmission accounted for, respectively, 40% and 38% of newly reported HIV cases in the West in 2011, whereas the epidemic in the Centre is predominantly concentrated in MSM. Although injection drug use remains the key driving force of the epidemic in the East, there is increasing evidence of sexual transmission from the core groups of injection drug users, and increasing spread within MSM. The pattern of transmitted drug resistance (TDR) is heterogeneous accross Europe; a significant number of clusters of TDR have been recently observed in several European countries.

Abstract
This study aimed to examine the influence of human herpesvirus type 8 (HHV-8) and herpes simplex virus type 2 (HSV-2) co-infections on apoptosis serum markers in human immunodeficiency virus (HIV)-infected patients. Sera from 110 HIV-infected and 59 HIV-uninfected individuals were analyzed for soluble Fas (sFas), sFas ligand (sFasL), caspase-8, and Bcl-2. The findings of HIV-infected patients with no co-infection (n = 37), HIV-infected patients with HHV-8 co-infection (n = 22), HIV-infected patients with HSV-2 co-infection (n = 51), and patients with HSV-2 co-infection and no HIV infection (n = 20) were compared to controls (reference group) with no HIV, HSV-2, and HHV-8 co-infections (n = 39). Soluble Fas and sFasL concentrations were the highest in HIV and HHV-8 co-infected patients (medians, 912.7 pg/ml and 74.3 pg/mL, respectively). No difference in caspase-8 concentrations was found, whereas Bcl-2 concentrations were the highest in HIV and HHV-8 co-infected individuals. Older age was associated with higher sFas (p < 0.001) and lower sFasL (p = 0.04) concentrations. In a robust regression model adjusted for age, the log-transformed sFas concentrations were significantly lower in HIV-infected patients with no co-infections (β = -0.244; p < 0.001) and higher in HIV and HHV-8 co-infected patients (β = 0.216; p = 0.012) compared to the reference group. Soluble FasL was significantly lower in HIV-infected patients with no co-infections (β = -0.284; p = 0.005) and in HIV-infected patients with HSV-2 co-infection (β = -0.381; p < 0.001) compared to the reference group. Soluble FasL was also higher in HIV and HHV-8 co-infected patients compared to controls (β = 0.248; p = 0.036). Our results suggest that HHV-8 and HSV-2 may have a significant effect on Fas-FasL-mediated apoptosis in HIV-1 patients. HHV-8 upregulates while HSV-2 downregulates sFas and sFasL.

Abstract
The occurrence of acute promyelocytic leukemia (APL) in HIV-infected patients has been reported in only five cases. Due to a very small number of reported HIV/APL patients who have been treated with different therapies with the variable outcome, the prognosis of APL in the setting of the HIV-infection is unclear. Here, we report a case of an HIV-patient who developed APL and upon treatment entered a complete remission. A 25-years old male patient was diagnosed with HIV-infection in 1996, but remained untreated. In 2004, the patient was diagnosed with primary central nervous system lymphoma. We treated the patient with antiretroviral therapy and whole-brain irradiation, resulting in complete remission of the lymphoma. In 2006, prompted by a sudden neutropenia, we carried out a set of diagnostic procedures, revealing APL. Induction therapy consisted of standard treatment with all-trans-retinoic-acid (ATRA) and idarubicin. Subsequent cytological and molecular ana?lysis of bone marrow demonstrated complete hematological and molecular remission. Due to the poor general condition, consolidation treatment with ATRA was given in March and April 2007. The last follow-up 14 months later, showed sustained molecular APL remission. In conclusion, we demonstrated that a complete molecular APL remission in an HIV-patient was achieved by using reduced-intensity treatment.

Abstract
Exposure prevention is the primary strategy to reduce the risk of occupational bloodborne pathogen infections in healthcare workers (HCW). HCWs should be made aware of the medicolegal and clinical relevance of reporting an exposure, and have ready access to expert consultants to receive appropriate counselling, treatment and follow-up.
Vaccination against hepatitis B virus (HBV), and demonstration of immunisation before employment are strongly recommended. HCWs with postvaccinal anti-HBs levels, 1-2 months after vaccine completion, >10 mIU/mL are considered as responders. Responders are protected against HBV infection: booster doses of vaccine or periodic antibody concentration testing are not recommended. Alternative strategies to overcome non-response should be adopted.
Isolated anti-HBc positive HCWs should be tested for anti-HBc IgM and HBV-DNA: if negative, anti-HBs response to vaccination can distinguish between infection (anti-HBs >50 mUI/ml 30 days after 1st vaccination: anamnestic response) and false positive results(anti-HBs >10 mUI/ml 30 days after 3rd vaccination: primary response); true positive subjects have resistance to re-infection. and do not need vaccination
The management of an occupational exposure to HBV differs according to the susceptibility of the exposed HCW and the serostatus of the source. When indicated, post-exposure prophylaxis with HBV vaccine, hepatitis B immunoglobulin or both must be started as soon as possible (within 1-7 days).
In the absence of prophylaxis against hepatitis C virus (HCV) infection, follow-up management of HCV exposures depends on whether antiviral treatment during the acute phase is chosen. Test the HCW for HCV-Ab at baseline and after 6 months; up to 12 for HIV-HCV co-infected sources. If treatment is recommended, perform ALT (amino alanine transferase) activity at baseline and monthly for 4 months after exposure, and qualitative HCV-RNA when an increase is detected.

Abstract
The main consequences of human immunodeficiency virus (HIV) infection and AIDS are frequent and persistent opportunistic infections at mucosal surfaces, but data upon impaired oral mucosal response in AIDS patients are still lacking. - The aim of this study was to determine salivary flow rates and peroxidase levels in unstimulated whole saliva in AIDS patients together with comparison to the healthy controls. Salivary peroxidase levels were determined according to Putter and Becker in 20 AIDS patients and 18 HIV-seronegative healthy controls. Statistical analysis was performed using Student t-test. Salivary peroxidase levels were significantly increased in the AIDS group (9.41 +/- 8.50 kU/L; p<0.009) when compared to the healthy controls (3.1 +/- 2.0 kU/L). Salivary flow rates were significantly decreased in AIDS patients (0.17+/-0.11 ml/min, p<0.009) when compared with healthy controls (0.58 +/- 0.19 ml/min). Elevated salivary peroxidase levels indicate increased salivary antimicrobial activity in AIDS patients.

Abstract
The prevalence of hepatitis C virus (HCV) infection in the population of human immunodeficiency virus 1 (HIV-1)-infected individuals from Slovenia and Croatia was determined. One hundred and sixty-six out of a total of 188 Slovenian HIV-1-infected individuals and 120 subjects who were randomly chosen out of a total 342 Croatian HIV-1 antibodies-positive individuals were tested for HCV infection. Detection of HCV antibodies was carried out by a third generation enzyme-linked immunoassay (ELISA) and the positive samples were additionally tested by a third generation immuno-blot assay. Additionally, the presence of HCV RNA was determined in all serum samples by a qualitative polymerase chain reaction (PCR). Twenty-four (14.5%) out of 166 Slovenian and 18 (15.0%) out of 120 Croatian HIV-1-infected individuals were HCV antibodies-positive. Nineteen out of 24 (79.2%) Slovenian and 13 out of 18 (72.2%) Croatian anti-HCV positive individuals were also viremic. HCV RNA was not detected in any of 244 HCV antibodies-negative/HIV-1-infected individual from both countries. A significant difference in the prevalence of HCV infection between blood (77.8% in Slovenia and 66.7% in Croatia) and sexual exposure risk groups (1.6% in Slovenia and 6.6% in Croatia) was found in both countries. In a study carried out on the highest proportion of entire population of HIV-1-infected individuals from a certain country or geographic region, Slovenia and Croatia were identified as countries with the second and third lowest prevalence of HCV infection among HIV-1/HIV-2 infected individuals worldwide.

Abstract
This study examines the presence of hepatitis B as a possible precursor marker for HIV/AIDS in 10 districts of Zagreb, Croatia. There were a total of 931 cases of hepatitis B in Zagreb in the period 1979-1995, the annual rate ranging from 3.1 to 15.4 per 10,000. The highest relative risk for hepatitis B for the 1979-1995 period was in the Pescenica district (Relative risk (RR): 1.4). There were 108 cases of HIV/AIDS diagnosed in Croatia in the period 1986-1996, with 34% from Zagreb. The highest relative risk for HIV/AIDS was within the Pescenica district (RR: 2.3). Pescenica had also a significantly higher incidence of hepatitis B when compared to other districts (p = 0.005). The cumulative incidence of hepatitis B in Zagreb was directly related to levels of neighborhood discomfort as determined by an index including unemployment, inflation and housing conditions (p = 0.005). This research demonstrates that the poor areas of the city with higher incidence of hepatitis B hold the greatest threat for the spread of HIV/AIDS.

Abstract
We present a case of meningitis and endocarditis caused by Streptococcus agalactiae (group B streptococcus) in an adult patient with human immunodeficiency virus (HIV) infection. To our knowledge, only four other cases of meningitis, none of which had concomitant endocarditis, have been reported so far. A 45-year-old homosexual patient presented with fever, confusion, and signs of meningeal irritation. Streptococcus agalactiae was cultured from the blood, urine, and cerebrospinal fluid (CSF). Diagnosis of meningitis caused by streptococcus agalactiae was made. On day 35, a heart murmur was noticed, and patient developed cardiac decompensation. Echocardiography revealed vegetations on the mitral and aortic valve. After nine weeks of antibiotic treatment, the patient was discharged from the hospital in good general condition, with improved CSF and echocardiographic findings.

Abstract
Human immunodeficiency virus (HIV) causes a chronic infection beginning in most individuals with an acute syndrome followed by an asymptomatic stage and progresses in untreated adults over a median of 10 years to the late stage called AIDS. The virus rapidly and enormously replicates from the initiation of infection. The principal immunodeficiency caused by HIV is depletion in the subset of T lymphocytes referred to as helper T cells. New anti-HIV drugs given in potent combination regimens have demonstrated impressive efficacy by both clinical and laboratory measures, and have provided evidence that drugs can suppress HIV replication and disease manifestations. HIV/AIDS is still uncommon in Croatia. In the period from 1986 to 2000, 171 patients with AIDS have been reported of whom 101 (59%) died. The incidence of AIDS in 2000 was about 4 cases per million inhabitants. Recent testing of injection drug users at a needle exchange program (Help, Split) revealed an HIV incidence of about 1%.

Abstract
BACKGROUND Body cavity-based lymphomas are rare malignancies in human immunodeficiency virus (HIV)-infected patients, but because of their unusual clinical, morphologic and immunophenotypic features, they are recognized as a distinct subgroup of lymphomas connected to human herpesvirus 8 (HHV-8) infection. CASE A 39-year-old, HIV-positive, homosexual man was admitted to the hospital because of a left-sided pleural effusion that contained malignant lymphoid cells. He responded partially to a low-dose cyclophosphamide/doxorubycin/vincristine/prednisone regimen and died five months after the diagnosis of lymphoma. On cytology, the sediments contained exclusively large, round, neoplastic, lymphoid cells with abundant basophilic cytoplasm and large, round nuclei with prominent nucleoli. Many cells had immunoblastic features, and some had plasmocytoid differentiation. Mitotic figures were numerous. On flow cytometry, the homogeneous population of large cells expressed CD45, CD38, HLA-DR and CD7 positivity. Other specific T-, B- and NK-cell markers tested negative. Polymerase chain reaction demonstrated Epstein-Barr virus (EBV) and HHV-8 in the malignant effusion. CONCLUSION Primary effusion from lymphoma with molecular evidence of HHV-8 and EBV coinfection represents a distinct clinical and morphologic entity in AIDS patients. However, immunophenotypic markers of malignant clones can be diverse in different cases.

Abstract
A computer based rule-generation system of Inductive Learning by Logic Minimization (ILLM) was used to determine the sufficient set of biochemical reactions and necessary conditions that have to be fulfilled for correct differentiation of enterococci recovered from humans. The simplest combination of physiological tests for differentiation Enterococcus faecalis from all other enterococcal species consisted of only 3 reactions. Reactions that tested the ability of acidification D-xylose, mannitol, L-arabinose and Na-pyruvate were useful for delineation of both E. faecalis and E. faecium from all other enterococci. For differentiation of all 12 currently known clinically significant species of enterococci any one of 3 sets of nine tests suggested by ILLM could be used. The tests suggested by ILLM were applied to 153 isolates of enteroccoci recovered at our Department of Microbiology and all E. faecalis (138, 90.2%), E. faecium (13, 8.5%) and E. avium strains (2, 1.3%) were correctly differentiated.

Abstract
The aim of this study was to analyse the lymphocyte subpopulations in the peripheral blood of HIV-1-infected adults to compare them with four patients with acute EBV infection. Lymphocyte subsets in 15 healthy controls, 40 HIV-1-infected adults and 4 EBV-infected patients with infectious mononucleosis were analysed by flow cytometry. The immunophenotyping of HIV-1-infected patients in different stages of disease showed a significant reduction in the percentage and absolute count of CD4+ T-lymphocytes, significantly increased percentage of CD8+ T-lymphocytes, inverted CD4/CD8 ratio and an increase in the expression of activation marker HLA-DR compared to controls. The immuno-phenotyping profiles of HIV and EBV infection share some similarities as they both result in the decreased percentage of CD4+ T-lymphocytes, increased CD8+ T-lymphocytes and an inverted CD4/CD8 ratio. Patients with HIV infection could be distinguished from patients with EBV infection by the absolute lymphocytosis and increased expression of HLA-DR seen in the patients with infectious mononucleosis. In conclusion, both HIV-1 and EBV profoundly change the distribution of lymphocyte subpopulations in the peripheral blood. It is our opinion that flow cytometry could be an aid in the rapid distinguishing of patients with suspected primary HIV-1 infection from those with infectious mononucleosis (before serology data are available).

Abstract
HIV-positive patients are liable to acquire opportunistic infections. Their liability to acquire other common infectious conditions is less frequently reported. In order to determine the frequency of urinary tract infections (UTI) in HIV-positive patients, we performed a retrospective analysis. The control group was formed from patients with community acquired pneumonia. We reviewed charts of 96 HIV-positive patients and of 314 patients in the control study group. The analysis has shown that patients with HIV had a UTI more frequently than the controls. Besides the difference in the frequency, we observed the difference in the etiology. Enterococci were the most frequent isolates in patients with HIV disease, whereas Escherichia coli was most frequently isolated in the controls. These facts should be taken into consideration when treatment of a UTI with suspected bacteremia in AIDS patients is initiated.

Abstract
A prospective, open, noncomparative study was conducted to assess the efficacy and safety of azithromycin given once daily for 3 or 5 days to eradicate Bordetella pertussis from the upper respiratory tract of infants and young children. Seventeen children received azithromycin in a dose of 10 mg/kg on day 1 followed by 5 mg/kg once daily for four consecutive days, and 20 were given 10 mg/kg once daily for 3 days. Seven days after the initiation of therapy, 33 of 35 (94.3%) patients had negative cultures for Bordetella pertussis. On day 14, cultures from all 34 evaluable patients were negative. These findings suggest that a controlled, comparative study of erythromycin versus short-term administration of azithromycin is justified.

Abstract
In this paper a novel computer example-based learning system (Inductive learning by logic minimization) was used to determine the sufficient set of biochemical reactions and necessary conditions that have to be fulfilled for the correct identification of enterococci isolated from human specimens. Several combinations for accurate identification of Enterococcus faecalis and Enterococcus feacium from other enterococci were found. The simplest combination set for E. faecalis identification consists of 3 reactions: growth in 0.04% K-tellurite, mannitol acidification, failure to acidify raffinose. The simplest set for E. faecium differentiation from other enterococcal species is performed by the following 3 reactions: failure to acidify D-xylose and Na-pyruvate, and acidification of L-arabinose. Only 4 tests are sufficient (acid from D-xylose, mannitol, L-arabinose and Na-pyruvate) for the correct identification of these two, the most frequently isolated species. If it is necessary to analyze all enterococcal species, then even three combinations of 9 tests for the correct differentiation of any of them, are available.

Abstract
Cytomegalovirus retinitis (CMVR) is a common opportunistic infection and a major cause of blindness in patients with AIDS. The aim of this study was to determine the frequency, clinical course and outcome of CMVR in patients treated at the University Hospital of Infectious Diseases "Dr. Fran Mihaljević" in Zagreb in the period from January 1995 to April 1996. CMVR was diagnosed in 8 (27.5%) of 29 patients with AIDS. The median CD4 lymphocyte count in patients with CMVR was 44 per mm3, six patients had less than 50 per mm3. Five patients died during the study period, the mean survival being 5.5 months. CMVR was present in both eyes in 5 (62.5%) patients at the time of diagnosis. Blindness in both eyes developed in 3 (37.5%) patients. In order to recognize and promptly treat CMVR frequent ophthalmologic examinations should be performed in patients with advanced HIV disease.

Abstract
This report reviews 55 cases of bacteremia due to group A streptococci (GAS) in patients treated at the University Hospital of Infectious Diseases, in Zagreb, Croatia, during the period 1974-1994. Clinical findings for 27 children (age, < 18 years) were compared with those for 28 adults. A clear predominance of the respiratory tract as a primary focus of infection in younger patients was observed (P = .00006). Children were more frequently colonized by GAS in their throats than were adults (P = .04). Suppurative osteoarticular metastatic foci were more often found in children (P = .02). Acute underlying conditions were more common in children (P = .04), whereas chronic underlying conditions were more common in adults (P = .00005). The case fatality rate was 23% among children (6 of 27) and 50% among patients aged > 60 years (5 of 10). The course of bacteremia due to GAS was benign in eight children (29.6%) and 12 adults (42.8%). Our experience suggests that there are significant differences in the presentation of bacteremia due to GAS in children and adults.

Abstract
In a one-year study at the University Hospital of Infectious Diseases in Zagreb, Croatia the rate of asymptomatic throat carriage of beta-haemolytic streptococci was investigated. Throat carriage was investigated in 1796 patients, none of whom had a sore throat nor signs and/or symptoms of a respiratory tract infection. The carrier rate of beta-haemolytic streptococci was 8.3%, for group A streptococci 6%, group B 1.3%, group C 0.3% and group F 0.1%. The highest rate was observed in the 6 to 14 year age group: 13.8% for all streptococcal groups, 11.7% for group A alone. The proportion of non-A streptococci was higher in older age groups. Tonsillectomised individuals were less frequently carriers. No sex or season-dependent variations were observed. In a four-month study of 629 patients with pharyngitis the throat cultures yielded: group A streptococci in 44.7%, group B in 1.7%, group C in 0.8%, and group G in 0.6% of the patients. Group A streptococci in 44.7%, group B in 1.7%, group C in 0.8%, and group G in 0.6% of the patients. Group A streptococcal rates in carriers compared to rates in patients with pharyngitis suggest that approximately one fourth of the schoolchildren with culture-positive pharyngitis actually are not truly infected, but only carriers currently having a sore throat of non-streptococcal etiology. Antibiotics were administrated to 605 (96.2%) patients with pharyngitis; in 571 (94.4%) of the cases before culture results became available. After culture-negative results were obtained the therapy was discontinued in only 28.5% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The pyrogenic exotoxin profiles were determined of group A streptococci isolated from patients in Zagreb, Croatia in the period 1989-1990. A total of 12 strains were studied, five from patients with serious infections and seven from patients with uncomplicated infections. Serotypes M1 and M3 were found in seven (58%) patients. Seven strains produced exotoxin A and ten strains exotoxin B. The proportion of exotoxin A and B producing strains in patients with severe infections (3 patients respectively) was similar to that found in patients with uncomplicated infections (4 and 7 patients respectively).

Abstract
We report clinical and laboratory findings in 11 previously healthy children with cytomegalovirus (CMV) mononucleosis and compare them with those of 18 adults with CMV mononucleosis and with those of 22 age-matched children with Epstein-Barr virus (EBV) mononucleosis. Exudative pharyngitis was more common in children whereas prolonged fever was more common in adults. Prominent lymphadenopathy and exudative pharyngitis, however, were less frequent in children with CMV mononucleosis than in those with EBV mononucleosis. Nevertheless, children with CMV mononucleosis are more likely to resemble those with EBV mononucleosis than adults with CMV mononucleosis.
