RESUMEN
This article describes the May Measurement Month (MMM) 2021 campaign, which was the fourth time this annual hypertension screening campaign was conducted in Albania, a Mediterranean country in southeastern Europe. The MMM21 was conducted during the period of 28 September-30 November 2021, in 32 sites across several districts of Albania. Overall, 11 788 participants aged ≥18 years were included (63% women), with a mean age of 49.7 ± 14.9 years. Blood pressure (BP) was measured three times with Omron sphygmomanometers (model M3, Omron Healthcare, Kyoto, Japan), which are automatic upper arm BP monitors. Hypertension was defined as SBP ≥ 140â mmHg or diastolic blood pressure (DBP) ≥ 90â mmHg (based on the mean of the second and third recordings for SBP and DBP, respectively) or on antihypertensive medication. Self-reported data included pre-existing conditions, physical activity, smoking, alcohol consumption, COVID-19 testing, and use of contraception in women. Overall, 47.3% of screened participants had hypertension. Of those with hypertension, 70.1% were aware of their condition and 67.0% were on antihypertensive medication. About half (49.3%) of participants on antihypertensive medication had controlled BP (<140/90â mmHg). On average, BP was higher in those on antihypertensive medication and with increasing alcohol intake but lower in those with a history of stroke and those with higher levels of physical activity, previous positive COVID-19 test, and contraception use in women. In Albania, the MMM campaign continues to contribute to the early detection of hypertension among adults. Hence, it constitutes a valuable opportunistic screening instrument among other routine tools applied in the general Albanian population.
RESUMEN
Background: Healthcare workers (HCWs) have experienced high rates of coronavirus disease 2019 (COVID-19) morbidity and mortality. We estimated COVID-19 2-dose primary series and monovalent booster vaccine effectiveness (VE) against symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron (BA.1 and BA.2) infection among HCWs in 3 Albanian hospitals during January-May 2022. Methods: Study participants completed weekly symptom questionnaires, underwent polymerase chain reaction (PCR) testing when symptomatic, and provided quarterly blood samples for serology. We estimated VE using Cox regression models (1 - hazard ratio), with vaccination status as the time-varying exposure and unvaccinated HCWs as the reference group, adjusting for potential confounders: age, sex, prior SARS-CoV-2 infection (detected by PCR, rapid antigen test, or serology), and household size. Results: At the start of the analysis period, 76% of 1462 HCWs had received a primary series, 10% had received a booster dose, and 9% were unvaccinated; 1307 (89%) HCWs had evidence of prior infection. Overall, 86% of primary series and 98% of booster doses received were BNT162b2. The median time interval from the second dose and the booster dose to the start of the analysis period was 289 (interquartile range [IQR], 210-292) days and 30 (IQR, 22-46) days, respectively. VE against symptomatic PCR-confirmed infection was 34% (95% confidence interval [CI], -36% to 68%) for the primary series and 88% (95% CI, 39%-98%) for the booster. Conclusions: Among Albanian HCWs, most of whom had been previously infected, COVID-19 booster dose offered improved VE during a period of Omicron BA.1 and BA.2 circulation. Our findings support promoting booster dose uptake among Albanian HCWs, which, as of January 2023, was only 20%. Clinical Trials Registration. NCT04811391.
RESUMEN
Background: Healthcare workers have experienced high rates of morbidity and mortality from coronavirus disease 2019 (COVID-19). Methods: A prospective cohort study was conducted in three Albanian hospitals between 19 February and 14 December 2021. All participants underwent polymerase chain reaction (PCR) and serological testing at enrolment, regular serology throughout, and PCR testing when symptomatic.Vaccine effectiveness (VE) against COVID-19 and against all severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections (symptomatic or asymptomatic) was estimated. VE was estimated using a Cox regression model, with vaccination status as a time-varying variable. Findings: In total, 1504 HCWs were enrolled in this study; 70% had evidence of prior SARS-CoV-2 infection. VE was 65.1% [95% confidence interval (CI) 37.7-80.5] against COVID-19, 58.2% (95% CI 15.7-79.3) among participants without prior SARS-CoV-2 infection, and 73.6% (95% CI 24.3-90.8) among participants with prior SARS-CoV-2 infection. For BNT162b2 alone, VE was 69.5% (95% CI 44.5-83.2). During the period when the Delta variant was predominant, VE was 67.1% (95% CI 38.3-82.5). VE against SARS-CoV-2 infection for the full study period was 36.9% (95% CI 15.8-52.7). Interpretation: This study found moderate primary series VE against COVID-19 among healthcare workers in Albania. These results support the continued promotion of COVID-19 vaccination in Albania, and highlight the benefits of vaccination in populations with high levels of prior infection.
RESUMEN
Background: Healthcare workers (HCWs) have been disproportionally affected by COVID-19. We investigated factors associated with two- and three-dose COVID-19 vaccine uptake and SARS-CoV-2 seropositivity among 1504 HCWs enrolled (19 February-7 May 2021) in a prospective COVID-19 vaccine effectiveness cohort in Albania through a secondary analysis. Methods: We collected sociodemographic, occupational, health, prior SARS-CoV-2 infection, and COVID-19 vaccination data from all HCWs at enrollment. Vaccination status was assessed weekly through June 2022. A serum sample was collected from all participants at enrollment and tested for anti-spike SARS-CoV-2 antibodies. We analyzed HCWs characteristics and outcomes using multivariable logistic regression. Findings: By 11 June 2022, 1337 (88.9%) HCWs had received two COVID-19 vaccine doses, of whom 255 (19.1%) received a booster. Factors significantly associated with receiving three doses (adjusted odds ratio (aOR), 95% CIs) were being ≥35 years (35-44 years: 1.76 (1.05-2.97); 45-54 years: 3.11 (1.92-5.05); ≥55 years: 3.38 (2.04-5.59)) and vaccinated against influenza (1.78; 1.20-2.64). Booster dose receipt was lower among females (0.58; 0.41-0.81), previously infected (0.67; 0.48-0.93), nurses and midwives (0.31; 0.22-0.45), and support staff (0.19; 0.11-0.32). Overall 1076 (72%) were SARS-CoV-2 seropositive at enrollment. Nurses and midwifes (1.45; 1.05-2.02), support staff (1.57; 1.03-2.41), and HCWs performing aerosol-generating procedures (AGPs) (1.40; 1.01-1.94) had higher odds of being seropositive, while smokers had reduced odds (0.55; 0.40-0.75). Interpretation: In a large cohort of Albanian HCWs, COVID-19 vaccine booster dose uptake was very low, particularly among younger, female, and non-physician HCWs, despite evidence demonstrating the added benefit of boosters in preventing infection and severe disease. Reasons behind these disparities should be explored to develop targeted strategies in order to promote uptake in this critical population. SARS-CoV-2 seroprevalence was higher among non-physicians and HCWs performing APGs. A better understanding of the factors contributing to these differences is needed to inform interventions that could reduce infections in the future. Funding: This study was funded by the Task Force for Global Health (US Centers for Disease Control (CDC) cooperative agreement # NU51IP000873) and the World Health Organization, Regional Office for Europe.
RESUMEN
COVID-19 vaccination leads to lower infection, morbidity, and mortality rates. However, COVID-19 infection leads to the development of coagulopathy-related manifestations in the form of both venous and arterial thromboembolism. This study aimed to assess the severity and mortality predictors of COVID-19 patients with thrombotic events in hospitalized patients in Albania. This is a retrospective study conducted in the "Mother Tereza" University Hospital of Tirana. Data were retrieved from the electronic databases of the hospital and only COVID-19 cases admitted to the infectious department during August−December 2020 were selected. Patients who, at admission, had a C-reactive protein (CRP) (mg/L) more than double and a D-dimer (ng/mL) more than triple according to international standards were included in the study. We performed univariate and multivariable logistic regression analysis, calculating unadjusted and adjusted odds ratios (ORs). A p-value < 0.05 was considered statistically significant. The study population included 60 hospitalized persons with a mean age of 64.4 years. Increased lactate dehydrogenase (LDH) (OR = 2.93; 95% CI = 0.82−10.42, p-value = 0.1) and increased creatine kinase (CK) (OR = 2.17; 95% CI = 0.63−7.46, p-value = 0.22) were related with increased probability of death. Moreover, a decreased number of lymphocytes was associated with increased mortality but with no statistical significance (OR = 0.40; 95% CI = 0.11−1.40, p-value = 0.15). The survival rate was higher for patients without comorbidities (p = 0.045). These results could serve as a baseline and as a reference for healthcare personnel who provides services to hospitalized patients with COVID-19. Further studies should take into consideration the vaccination of the population as well as including more hospitals and patients.
RESUMEN
INTRODUCTION: Critical questions remain about COVID-19 vaccine effectiveness (VE) in real-world settings, particularly in middle-income countries. We describe a study protocol to evaluate COVID-19 VE in preventing laboratory-confirmed SARS-CoV-2 infection in health workers (HWs) in Albania, an upper-middle-income country. METHODS AND ANALYSIS: In this 12-month prospective cohort study, we enrolled HWs at three hospitals in Albania. HWs are vaccinated through the routine COVID-19 vaccine campaign. Participants completed a baseline survey about demographics, clinical comorbidities, and infection risk behaviours. Baseline serology samples were also collected and tested against the SARS-CoV-2 spike protein, and respiratory swabs were collected and tested for SARS-CoV-2 by RT-PCR. Participants complete weekly symptom questionnaires and symptomatic participants have a respiratory swab collected, which is tested for SARS-CoV-2. At 3, 6, 9 months and 12 months of the study, serology will be collected and tested for antibodies against the SARS-CoV-2 nucleocapsid protein and spike protein. VE will be estimated using a piecewise proportional hazards model (VE=1-HR). BASELINE DATA: From February to May 2021, 1504 HWs were enrolled. The median age was 44 (range: 22-71) and 78% were female. At enrolment, 72% of participants were seropositive for SARS-CoV-2. 56% of participants were vaccinated with one dose, of whom 98% received their first shot within 4 days of enrolment. All HWs received the Pfizer BNT162b2 mRNA COVID-19 vaccine. ETHICS AND DISSEMINATION: The study protocol and procedures were reviewed and approved by the WHO Ethical Review Board, reference number CERC.0097A, and the Albanian Institute of Public Health Ethical Review Board, reference number 156. All participants have provided written informed consent to participate in this study. The primary results of this study will be published in a peer-reviewed journal at the time of completion. TRIAL REGISTRATION NUMBER: NCT04811391.

This article discusses the results of the May Measurement Month (MMM) 2019 campaign, which contributed to a third round of MMM hypertension screening campaigns carried out in Albania, a transitional country in the Western Balkans. The hypertension screening campaign in Albania was carried out during the period 1-31 May 2019 in 30 sites in many districts of the country. Overall, 19 154 participants aged ≥18 years were included (approximately 68% of these were women), with an overall mean age of 47.0 ± 15.3 years. Blood pressure (BP) was measured with OMRON sphygmomanometers (Omron Healthcare, Kyoto, Japan). Hypertension was defined as systolic BP ≥140 mmHg, or diastolic BP ≥90 mmHg, or on treatment for hypertension. Self-reported data consisted of height and weight, pre-existing conditions, including smoking status and alcohol consumption. Overall, the proportion of participants with hypertension was 38.6%. Less than two-thirds (64.7%) of hypertensive individuals were aware of their condition. Also, less than half (48.3%) of participants on antihypertensive medication had controlled BP (<140/90 mmHg). The most sizable correlations of high BP were with known hypertension status, use of antihypertensive medication, and obesity. The MMM campaign contributes to routine hypertension screening in Albania. Hence, health professionals and policymakers in Albania should act on the findings of MMM screening campaigns and continue its support as a valuable tool for early detection of hypertension in the general population.
RESUMEN
OBJECTIVES: Carbapenemases represent a public health threat, as they can spread through horizontal gene transfer and cause outbreaks. New Delhi metallo-ß-lactamase-1 (NDM-1) is a metallo-ß-lactamase that has spread rapidly in the last decade, causing worldwide alarm. This study aimed to describe the first isolate of NDM-1-producing and extensively drug resistant Klebsiella pneumoniae in Albania, its clinical context and genetic characterization. METHODS: Strain was isolated from both oral and rectal intensive care unit admission screening swabs of a 70-year-old male patient with no history of international travel in the previous 6 months. Sequencing was performed by Illumina NextSeq500 platform, with a paired-end run of 2 by 150bp, after Nextera XT paired-end library preparation. Sequencing reads were assembled using SPAdes Genome (version 3.6.1) with accurate de novo settings. The assembled contigs were uploaded into the online tools: BIGSdb-Kp, ResFinder and PlasmidFinder. RESULTS: Isolate was resistant to all tested antibiotics but tigecycline and trimethoprim-sulfamethoxazole. Sequencing revealed the presence of acquired resistance genes conferring resistance to ß-lactams (blaNDM-1, blaCMY-6, blaCTX-M-15and blaSHV-28), aminoglycosides (rmtC, aac(6')-Ib3), fluoroquinolones (oqxA, oqxB, aac(6')-Ib-cr), fosfomycin (fosA) and sulfonamides (sul1). The blaNDM-1 gene was located on an IncA/C2 plasmid. Plasmid mediated mcr-1 to mcr-8 genes were absent in both isolates. Resistance to colistin was due to an amino acid substitution (Thr157Pro) in PmrB protein. CONCLUSIONS: NDM-1-producing Enterobacteriaceae are spreading in the Balkans. Identification of NDM-1-producing and extensively drug resistant K. pneumoniae ST15 in Albania is a cause for serious concern. There should be a continuous national and Balkan multinational surveillance of blaNDM-1-carrying isolates.

INTRODUCTION: Status asthmaticus is a life-threatening condition characterized by progressive respiratory failure due to asthma that is unresponsive to standard therapeutic measures. We used extracorporeal membrane oxygenation (ECMO) to treat patients with near-fatal status asthamticus who did not respond to aggressive medical therapies and mechanical ventilation under controlled permissive hypercapnia. MATERIALS AND METHODS: Between January 2011 and October 2015, we treated 16 adult patients with status asthmaticus (8 women, 8 men, mean age: 50.5±10.6years) with veno-venous ECMO (13 patients) or veno-arterial (3 patients). Patients failed to respond to conventional therapies despite receiving the most aggressive therapies, including maximal medical treatments, mechanical ventilation under controlled permissive hypercapnia and general anesthetics. RESULTS: Mean time spent on ECMO was 300±11.8 hours (range 36-384 hours). PaO2, PaCO2 and pH showed significant improvement promptly after ECMO initiation p=0.014, 0.001 and <0.001, respectively, and such values remained significantly improved after ECMO, p=0.004 and 0.001 and <0.001, respectively. The mean time of ventilation after decannulation until extubation was 175±145.66 hours and the median time to intensive care unit discharge after decannulation was 234±110.30 hours. All 16 patients survived without neurological sequelae. CONCLUSIONS: ECMO could provide adjunctive pulmonary support for intubated asthmatic patients who remain severely acidotic and hypercarbic despite aggressive conventional therapy. ECMO should be considered as an early treatment in patients with status asthmaticus whose gas exchange cannot be satisfactorily maintained by conventional therapy for providing adequate gas change and preventing lung injury from the ventilation.

INTRODUCTION: Tuberculosis affected about 8.5 million patients in 2011. Numerous efforts are needed to reduce the pool of individuals with latent TB infection (LTBI). The aim of the study was to describe a tuberculin skin testing (TST) survey carried out in Albania to estimate the LTBI burden; furthermore, knowledge of TB was evaluated through an ad hoc questionnaire. METHODOLOGY: A TST survey was performed in three geographical districts of Albania: Tirana-Kamez, Vlora, and Dibra. Cluster sampling was carried out of young Albanian students. In addition, the same students were given a questionnaire to assess their knowledge, attitudes, and any misconceptions about TB. The mean (standard deviation) age of the individuals, according to their educational level, was the following: grade five, 11.03 (0.18) years; grade six, 12.02 (0.17) years; and grade seven, 13.02 (0.16) years. RESULTS: The TST induration size was read in 4,648 students. About 5.0% showed a reaction >5 mm, with a significant variability in the districts selected (12.1% in the district of Dibra). An induration diameter >15 mm was found mainly in those areas with high TB incidence (i.e., Tirana-Kamez and Dibra). About 13% of the students had no knowledge of TB. CONCLUSION: LTBI prevalent cases are estimated to be low in Albania, although there are areas where the TB management should be improved to reduce the probability of Mycobacterium tuberculosis transmission. The level of knowledge about TB disease is inadequate and new public health strategies should be implemented, focusing on educational TV programs.
