Acquired immune deficiency syndrome (AIDS) and late presentation in Poland - data from Test and Keep in Care (TAK) Polska project. HIV Med 2021; 22:387-396. [PMID: 33410278 DOI: 10.1111/hiv.13041] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 10/17/2020] [Accepted: 11/26/2020] [Indexed: 01/04/2023]
Abstract
OBJECTIVES Late presentation (LP) at HIV diagnosis is associated with worse prognosis and an increase in the number of new infections. We analyse the proportion of patients diagnosed late and factors related to LP in Poland in 2016-2017. METHODS Data were obtained from 13 out of 17 HIV centres in Poland from 2016 and 2017, including date of diagnosis, age, sex, transmission route, anti-hepatitis C virus (anti-HCV), Venereal Diseases Research Laboratory (VDRL) antibodies, AIDS diagnosis, baseline HIV viral load and CD4 count. RESULTS Out of 1522 patients, 88.9% were male with median age of 33.6 years. Men who have sex with men (MSM) comprised 69.4% of all new infections, heterosexual route of transmission (HTX) 18.2% and injecting drug use (IDU) 4.7%. Late presenters comprised 44.8% of the study group. Factors associated with LP were female sex [odds ratio (OR) = 1.5, 95% confidence interval (95% CI): 1.09-2.08], older age (OR = 1.59, 95% CI: 1.42-1.79 per decade), route of transmission (HTX: OR = 1.96, 95% CI: 1.50-2.56; IDU: OR = 3.17, 95% CI: 1.92-5.37), positive HCV results (OR = 1.90, 95% CI: 1.23-2.95) and syphilis diagnosis (OR = 2.06, 95% CI: 2.29-3.31). Adjusting for these factors, the only independent factors associated with LP were age (OR = 1.52, 95% CI: 1.35-1.71) and route of transmission (HTX: OR = 1.73, 95% CI: 1.23-2.44; IDU: OR = 2.24, 95% CI: 1.25-4.10). CONCLUSIONS Late presentation in Poland follows European trends. A total of 44.8% of all newly diagnosed patients in Poland continue to present late or at the AIDS stage. Independent factors associated with LP/AIDS were older age, IDU and HTX. Patients from these groups should be targeted to improve early diagnosis and medical care.

Abstract
INTRODUCTION Delay in HIV diagnosis and consequently late care entry with low CD4 counts remain a major challenge for the control of the HIV/AIDS epidemic. The aim of this study was to analyse the evolution of characteristics of the HIV epidemic in Poland. METHODS Cross-sectional data were collected for 3972 HIV-infected patients followed up in 14 of 17 Polish HIV treatment centres in the years 2000-2015. Clinical data were analysed and factors associated with late presentation (baseline CD4 count < 350 cells/μL or history of AIDS-defining illness) and advanced HIV disease (baseline CD4 count < 200 cells/μL or history of AIDS) were identified. RESULTS The majority (57.6%) of patients entered care late, while 35.6% presented with advanced HIV disease. The odds of being linked to care late or with advanced HIV disease increased consistently across age categories, increasing from 2.55 [95% confidence interval (CI) 1.46-4.47] for late presentation and 3.13 (95% CI 1.49-6.58) for advanced disease for the 21-30-year-old category to 5.2 (95% CI 1.94-14.04) and 8.15 (95% CI 2.88-23.01), respectively, for individuals > 60 years of age. Increased risks of late entry and advanced HIV disease were also observed for injecting drug users [adjusted odds ratio (aOR) 1.74 (95% CI 1.16-2.60) and 1.55 (95% CI 1.05-2.30), respectively], with lower aOR associated with the men who have sex with men transmission route [aOR 0.3 (95% CI 0.31-0.59) and 0.39 (95% CI 0.29-0.53), respectively]. The frequencies of cases in which patients were linked to care late and with advanced HIV disease decreased over time from 67.6% (2000) to 53.5% (2015) (P < 0.0001) and from 43.5% (2000) to 28.4% (2015) (P = 0.001), respectively. CONCLUSIONS Despite improvements over time, most patients diagnosed with HIV infection entered care late, with a third presenting with advanced HIV disease. Late care entry remains common among people who inject drugs and heterosexual groups.

Auditing HIV Testing Rates across Europe: Results from the HIDES 2 Study. PLoS One 2015; 10:e0140845.

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
OBJECTIVES The aim of the study was to investigate the organization and delivery of HIV and tuberculosis (TB) health care and to analyse potential differences between treatment centres in Eastern (EE) and Western Europe (WE). METHODS Thirty-eight European HIV and TB treatment centres participating in the TB:HIV study within EuroCoord completed a survey on health care management for coinfected patients in 2013 (EE: 17 respondents; WE:21; 76% of all TB:HIV centres). Descriptive statistics were obtained for regional comparisons. The reported data on health care strategies were compared with actual clinical practice at patient level via data derived from the TB:HIV study. RESULTS Respondent centres in EE comprised: Belarus (n = 3), Estonia (1), Georgia (1), Latvia (1), Lithuania (1), Poland (4), Romania (1), the Russian Federation (4) and Ukraine (1); those in WE comprised: Belgium (1), Denmark (1), France (1), Italy (7), Spain (2), Switzerland (1) and UK (8). Compared with WE, treatment of HIV and TB in EE are less often located at the same site (47% in EE versus 100% in WE; P < 0.001) and less often provided by the same doctors (41% versus 90%, respectively; P = 0.002), whereas regular screening of HIV-infected patients for TB (80% versus 40%, respectively; P = 0.037) and directly observed treatment (88% versus 20%, respectively; P < 0.001) were more common in EE. The reported availability of rifabutin and second- and third-line anti-TB drugs was lower, and opioid substitution therapy (OST) was available at fewer centres in EE compared with WE (53% versus 100%, respectively; P < 0.001). CONCLUSIONS Major differences exist between EE and WE in relation to the organization and delivery of health care for HIV/TB-coinfected patients and the availability of anti-TB drugs and OST. Significant discrepancies between reported and actual clinical practices were found in EE.

Abstract
40Ca+;{40,48}Ca,46Ti reactions at 25 MeV/nucleon have been studied using the 4pi CHIMERA detector. An isospin effect on the competition between fusionlike and binarylike reaction mechanisms has been observed. The probability of producing a heavy residue is lower in the case of N approximately Z colliding systems as compared to the case of reactions induced on the neutron rich 48Ca target. Predictions based on constrained molecular dynamics II calculations show that the competition between fusionlike and binary reactions in the selected centrality bins can constrain the parametrization of the symmetry energy and its density dependence in the nuclear equation of state.

Abstract
A new reaction mechanism of violent reseparation of a heavy nucleus-nucleus system, 197Au + 197Au, into three or four massive fragments in collisions at 15 MeV/nucleon has been observed. After reseparation, the fragments are almost exactly aligned, thus showing a very short time scale of the reseparation process, of about 70-80 fm/c.

Abstract
Anaplasma phagocytophilum infection is a recently emerged tick-borne zoonosis. The bacterium's reservoirs likely comprise cervids, some ruminants, rodents, and perhaps other small and intermediate-size mammals; the main vector in Europe is the Ixodes ricinus tick. The Białowieza Primeval Forest is an ecosystem with a known prevalence of tick-borne pathogens. We studied the root-vole Microtus oeconomus to evaluate the natural infection of A. phagocytophilum. Intragranulocytic bacterial clusters (morulae) were not seen, but the A. phagocytophilum-specific nested polymerase chain reaction (PCR) product, targeting the rrs gene, was detected in two out of 30 rodent samples (GenBank accession nos. DQ361024 and DQ361025). Twenty-six root vole (86.6%) hosted ticks, mainly Dermacentor reticulatus larvae and nymphs. Only two rodents were parasitazed by I. ricinus single larvae. These data show the presence of natural infection of A. phagocytophilum among the root-vole M. oeconomus in the Białowieza Primeval Forest ecosystem.

Abstract
PURPOSE Human granulocytic anaplasmosis, former ehrlichiosis, is a tick-borne zoonosis of increasing recognition. The aim of the study was: 1) to assess the prevalence of Anaplasma phagocytophilum infection in Ixodes ricinus ticks collected in recreational forests in Bialystok vicinity, the capital of podlaskie voivodship; 2) to evaluate the prevalence of IgG and IgM antibodies to A. phagocytophilum among forestry rangers from the same region. RESULTS Of the 372 ticks examined, 54 (14.5%) yield the positive PCR reaction. The highest prevalence was detected in females, up to 27.8% (37/133), almost one third lower in males--9.2% (13/142), followed by nymphs--4.1% (4/97). Human seropositivity study revealed IgG antibodies against A. phagocytophilum in 9 out of 231 individuals (3.9%). No IgM antibodies were found. Sixty-seven individuals 67/231 (29%) reported erythema migrans. IgM anti-Borrelia burgdorferi antibodies were detected in 32 out of 121 (26.4%) persons tested, IgG--in 43 out of 231 (18.6%). CONCLUSIONS The data obtained show relatively low A. phagocytophilum seroreactivity among professionally exposed to tick group of forestry workers despite high A. phagocytophilum infection level in the competent vector--I. ricinus ticks.

Abstract
Many hepatitis C virus (HCV)-infected individuals do not have any obvious risk factors and one of the putative sources of infection may be inadvertent exposure to infected blood or body fluids in the clinical setting. The aim of this study was to assess the role of medical procedures in transmission of hepatitis C in north-eastern Poland. In total, 194 patients with chronic hepatitis C were eligible for the study. The control group consisted of 275 age- and sex-matched individuals. Patients with a history of intravenous drug use were excluded. On multivariate analysis, transfusions [odds ratio (OR) = 3.7, 95% confidence interval (CI) 2.2-6.3], minor surgery (OR = 3.2, 95% CI 1.5-6.7) and dental care (OR = 2.3, 95% CI = 1.4-4.0) were independently associated with HCV infection. We conclude that apart from transfusion, minor medical procedures and dental care may carry a significant risk of hepatitis C infection. Improvements in basic hygiene routines and strict adherence to universal precautions may be essential to prevent iatrogenic transmission of the infection.

Abstract
PURPOSE We address the question whether lamivudine treatment modulates serum concentrations of hyaluronic acid and whether the pre-treatment HA level can give the information about the presumptive result of treatment and whether HA level evaluation can be useful in monitoring the antiviral therapy in chronic hepatitis B. MATERIAL AND METHODS Forty-nine patients, 31 man, aged 40 +/- 2.5 years were treated with 100 mg lamivudine per day for 48 weeks. Serum hyaluronic acid level was determined using enzyme-linked binding protein commercial assay (Corgenix Inc., USA). RESULTS The mean HA pre-treatment levels were higher than among controls (69.6 +/- 11.6 ng/ml vs 36.5 +/- 7.6 ng/ml, mean +/- SEM) and correlated with AST activity, p = 0.002; GGT activity, p = 0.006; ALP activity p < 0.001; prothrombin time, p = 0.01; and peripheral blood platelets count, p = 0.001 but did not correlated with ALT activity. The pre-treatment HA concentration correlated also with interlobular necroinflammatory activity score, p = 0.049 and with fibrosis score, p = 0.026, according to Scheuer classification. The mean HA levels decreased gradually during lamivudine treatment, up to levels lover than among controls (26.3 +/- 5.7 ng/ml). There were not significant differences in pre-treatment levels observed between patients neither with HBs seroconversion versus those without it, nor between patients with HBe seroconversion versus those without it and among patients with normalization of ALT activity versus ones without it. CONCLUSIONS Serum hyaluronic acid level decreases during lamivudine treatment both in patients with HBeAg seroconversion and without it; serum hyaluronic acid pretherapy levels correlate with necroinflammatory lobular activity score and with liver fibrosis score; serum hyaluronic acid is of no predictive value for lamivudine therapy response; serum hyaluronan may be valuable complementary marker in chronically HBV infected patients.

Abstract
Hepatitis C virus and hepatitis D virus have been shown to suppress HBsAg synthesis. Thus it is possible that HDV infection occurs despite the lack of detectable HBsAg. The aim of our study was to (a) determine the prevalence of HDV infection in patients with chronic hepatitis C (b) compare it with the prevalence of HDV infection in HBsAg positive patients with hepatitis B. The study group consisted of 51 chronic hepatitis C patients, 30 HIV infected drug addicts (27 of them were also positive for anti-HCV) and 102 hepatitis B patients. The participants were tested for anti-HDV, anti-HCV and HBsAg. All anti-HCV positive patients were negative for anti-HDV. Four individuals with anti-HDV belonged to hepatitis B group and constituted 3.9% of all HBsAg positive subjects. We conclude that (a) there is currently no evidence of HDV infection among HCV infected patients in our region (b) hepatitis delta infection is rare in north-eastern Poland.

Abstract
We evaluated the prevalence of hepatitis B virus (HBV) markers and established HBV vaccination status among 111 patients with hepatitis C virus (HCV) infection. A history of HBV immunisation was recorded in 30 patients (27.0%) and only 17/30 (66.7%) had anti-HBs level > or =10 mIU/ml. All patients were HBsAg-negative and 22.2% of nonvaccinated subjects had evidence of HBV infection as determined by anti-HBc presence. Among patients with anti-HBc in 7/18 cases (38.9%) anti-HBc was the only marker of HBV infection (without anti-HBs). The prevalence of anti-HBc was significantly higher among patients who reported a history of acute hepatitis. In conclusion the prevalence of HBV markers in patients with HCV infection in north-eastern Poland is similar to the prevalence in general population, which suggests no increased risk for nosocomial HBV infection among those individuals. HCV infection seems to favour unusual serological pattern of HBV infection with anti-HBc as the only marker. HBV vaccine use is low among patients with HCV infection in north-eastern Poland.

Abstract
The aim of this study was to determine the prevalence of anti-HAV antibodies and factors associated with HAV infection amongst patients with chronic hepatitis C. The prevalence of anti-HAV antibodies in hepatitis C patients was 69.2% and did not differ significantly from 63.3% observed in the group of healthy controls. In patients with chronic hepatitis C the occurrence of HAV antibodies was not associated with the duration of HCV infection, history of transfusions and surgeries. There was a tendency towards higher prevalence of anti-HAV in persons with history of numerous hospitalizations (60.8% of persons with the history of up to 5 hospitalizations were positive for anti-HAV and more than 84.6% of those with more than 5 hospitalizations). Only 38.5% of patients under 35 years had anti-HAV antibodies. In conclusion immunization against hepatitis A should be recommended for hepatitis C patients under 35 years of age, most of whom are not immune to HAV. Testing for anti-HAV prior to vaccination should be performed in individuals older than 35 because natural immunity is common.

Abstract
Human granulocytic ehrlichiosis (HGE) is an emerging tickborne zoonosis. First described in the USA, it is being increasingly reported from several European countries. This study was undertaken to provide serological and molecular evidence of the occurrence of the HGE focus in the Białowieza Primeval Forest, located in northeastern Poland. To this end, the seroprevalence of HGE in this area, where Lyme borreliosis and tickborne encephalitis are highly endemic, was determined by means of an indirect immunofluorescence antibody assay. In addition, the frequency of granulocytic Ehrlichia spp. infection in Ixodes ricinus ticks from the same area was estimated using a polymerase chain reaction method with EHR 521 and EHR 747 primers, which amplified a fragment of 16S rDNA. The rate of seropositivity for HGE was 6.2% (8/130 subjects). Individuals seropositive for Lyme borreliosis were more likely to have anti-HGE antibodies than seronegative ones (P<0.05; OR=6.34, 95%CI=1.12-36.98). There was no association between self-reported frequency of tick bites or forestry employment and HGE seropositivity. Sixty of 376 (16%) Ixodes ricinus ticks tested were positive for the Ehrlichia phagocytophila genogroup by polymerase chain reaction. Ehrlichial DNA was present in 59 of 302 (19.5%) adult ticks and in 1 of 74 nymphs (1.4%). There was a significantly higher infection rate among female ticks (32.9%; 49/149) than among male ticks (6.5%; 10/153) (P<0.05). Dual infection with Ehrlichia spp. and Borrelia burgdorferi sensu lato was detected in 10 samples that were positive for ehrlichiae. The results obtained confirm the perpetuation of the HGE agent in the primeval forest ecosystem of northeastern Poland.

Abstract
Chronic hepatitis C often occurs among patients with different diseases and may influence their natural history. From the other hand coexisting diseases may modify the hepatitis C infection. We present a case of a male patient with the histiocytosis X, earlier called Hand-Schüller-Christian disease with hepatitis C virus infection. The mild course of the chronic hepatitis C, not requiring anti-viral therapy, may be the result of immunomodulation relevant to Hand-Schüller-Christian disease.

Abstract
Cystic and alveolar echinococcosis, parasitic diseases, caused in humans by the larval stage of tapeworm Echinococcus granulosus and E. multilocularis are rare diseases in Poland. We have diagnosed 71 patients with cystic echinococcosis and 10 patients with alveolar echinococcosis during last 12 years. Echinococcosis still create significant diagnostic difficulties, particularly alveolar one. Progress and actually available radiological imaging techniques, which can be applied in the cystic and alveolar echinococcosis diagnostics, are presented. Ultrasound appearance, CT, MRI images are described. Own experience with Proton Magnetic Resonans Spectroscopy in two patients with recurrent alveolar echinococcosis are presented.

Abstract
Hepatitis C is a disease with varying rates of progression. The role of hepatitis B virus (HBV) as a cofactor in the development of hepatitis C virus (HCV)-related cirrhosis and hepatocellular carcinoma (HCC) has been suggested and the use of HBV vaccine in all HCV-infected patients has been advocated. This review presents the implications of HBV and HCV coinfection and addresses the issues of HBV vaccine immunogenicity and safety in patients with chronic HCV infection.

Abstract
Influenza, a disease known for centuries, continues to be a major medical problem throughout the world with substantial economical and health impact. The risk of death related to influenza is higher among individuals over 65 years of age and those with chronic diseases. Vaccination against influenza was successfully applied in massive prophylaxis of the disease in different countries for many years. Although there are some well known and monitored adverse reactions to influenza vaccines, the evidence whether influenza vaccination might be causally associated with higher risk of Guillain-Barré syndrome is not clear. In this paper the available literature data concerning this problem were reviewed. Own experiences on influenza vaccination and plasmapheresis treatment of Guillain-Barré syndrome were presented.

Abstract
Since the sensitivity and specificity of serologic tests for echinococcosis is low, the role of imaging techniques is increasing. The goal of this study was to determine the usefulness of ultrasonography in diagnostics and classification of liver hydatid cysts and in the follow up after antiparasitic treatment. The study group of 35 persons, 26 women (mean age 42 years) and 9 men (mean age 39 years) was selected. The echography diagnosis was made using Toschiba scanner (SSH 140 A) with 3.75 and 7.5 MHz transducers. All 35 patients had positive results of serological tests for echinococcosis (EIA and/or indirect hemagglutination). The liver hydatid cysts (h.c.) are classified into seven types according to Caremani et all: I--simple h.c., II--multiple h.c., III--h.c. with detachment of the wall, IV--h.c. with mixed pattern with or without septations, V--heterogenous h.c., VI--hyperechoic h.c., VII--calcified h.c. The antiparasitic chemiotherapy with albendazole (10 mg/kg) was applied to 23 patients with total number of 59 h.c. of types I, II, III, IV, V. The observation points that cysts types I, II, III, IV, V respond to antiparasitic treatment. Our findings show that the sonographic patterns of cyst degeneration are seen with greater frequency in treated cysts than in nontreated ones.

Abstract
Hydatid liver disease is the most common form of human echinococcosis in Poland. Epidemiological data show a rising number of cases recognised last years. It is probably because of easier availability of ultrasound examination and computed tomography in the diagnostic procedures. While surgery remains the only approach for a radical cure, the chemotherapy with albendazole has became a useful advance in the management of cystic echinococcosis for the problem patient (inoperable disease, widely disseminated cysts, high surgical risk, etc.). The authors describe a patient with hydatid liver disease successfully treated with albendazole as a alternative treatment to surgery. A cyclic treatment of 28 days with 2 week break in between for 9 months with low doses of albendazole (6 mg/kg) resulted in clinical improvement and involution of hepatic cysts.

Abstract
Most toxoplasmosis infections occur in the brain. Cerebral toxoplasmosis is a specially serious complication in patients with AIDS. Similarly to other opportunistic pathogens, Toxoplasma gondii causes rapidly progressive, and often fatal disease in immunosuppressed patients. The diagnosis is difficult, since no sensitive and specific non-invasive diagnostic tests exist. The subject of our study is a 27-old female initially diagnosed with metastasis in central nervous system.

Abstract
Vaccination against tick-borne encephalitis with FSME-Immun vaccine was started in the Department of Infectious Diseases, University Medical School of Białystok, Poland, in 1992. No serious adverse reactions after vaccine administration were observed. Post-vaccine side effects were reported in 242 (11.3%) persons after the first dose (n = 2,135) and only in 14 patients (1.2%) after the second one (n = 1,183). These effects were mild and transitory. No relationship was observed between the frequency of adverse reactions, general or local, and the initial anti-TBE virus antibody titres or the age of the immunized individuals. Post-vaccine side effects were reported significantly more frequently among people not bitten by ticks.

Abstract
The central nervous system (CNS) is the most common site of Toxoplasma gondii infection in HIV-positive patients, mainly due to reactivation of Toxoplasma cysts. The diagnosis is difficult since no sensitive and specific non-invasive diagnostic tests exist. The patient may present with rather unspecific signs and symptoms. We present atypical course of CNS-toxoplasmosis in two HIV-positive persons.

Abstract
The availability of more reliable assays made infections caused by hepatitis C virus (HCV) emerging as an extremely common and insidiously progressive disease. Since 1993, in 51 out of 798 patients admitted to Department of Infectious Diseases with acute hepatitis, HCV was diagnosed as a causative agent. Seventy one percent of acute hepatitis C cases were hospital associated and city residents represented the majority of all cases. The epidemiological data and clinical course of acute hepatitis C was analysed and compared with acute hepatitis B. The frequency of acute hepatitis C increased during last 3 years in Białystok region. The clinical course of acute hepatitis C was generally milder than acute hepatitis B, with lower aminotransferases activities and bilirubin level.

Abstract
Concentration of neopterin (NPT) was measured in 3-6 months intervals in the serum of HIV-infected drug users taking continuously intravenous drugs and those who stopped the habit (MONAR, ZOZ). After 6-12 months of observation the mean NPT concentration was higher in the active drug users what was statistically essential. The outcome of our study indicates that current state of the patient concerning taking of drugs must be taken under consideration when NPT concentration is assessed as marker of progression of HIV disease.
