Global Bibliometric Analysis of Leishmaniasis Literature for the Last 20 Years and Investigating the Contribution of Türkiye.

OBJECTIVE: Leishmaniasis is a global health problem seen in more than 98 countries. The aim of this study is to conduct a bibliometric analysis of worldwide scientific outputs related to leishmaniasis and to provide a perspective for researchers on this topic. It also aimed to investigate the contribution of Türkiye to the leishmaniasis literature. METHODS: This study was conducted using scientometric methodologies on leishmaniasis in the Web of Science database between 2003 and 2022. The visualizations were made with Vosviewer program. The most published institutions and organizations, countries, authors, trends in the number of publications and citations by year, H-indexes of the mostly publishing countries, the most popular keywords, scientific collaborations between countries, and many other bibliometric parameters were analyzed. RESULTS: In the last 20 years, research on Leishmania has been conducted in 143 different countries/regions. Brazil is the leading country with 4.463 articles (29.071%). The United States of America, India, Iran, and Spain published more than 1.000 articles, followed by European countries (Spain, United Kingdom, France, Germany, and Italy). CONCLUSION: The number of publications, especially in endemic areas, was found to be limited other than Brazil. Studies in this area should be supported to ensure the eradication of the disease.

Ocular Involvement of Brucellosis: A Pooled Analysis Study.

AIM: Brucellosis may affect the eye to varying degrees. The aim of this study was to investigate the ocular involvement of brucellosis and highlight key points. MATERIAL AND METHODS: Published literature in English language on the ocular involvement of brucellosis within last 30 years was evaluated. The PubMed international database was screened using certain keywords. RESULTS: The study included 27 publications evaluating a total of 159 cases. The most common types of ocular involvement were uveitis (52.2%) and conjunctivitis (17.6%). Most cases had concomitant systemic brucellosis (27.7%), and the most commonly used diagnostic method was a serological test (92.4%). Of all the patients, 37.1% recovered with sequelae. CONCLUSION: Brucellosis may cause a wide range of ophthalmic manifestations, and an overlooked or late diagnosis may also lead to the development of sequelae or loss of vision. A routine ophthalmologic examination should be performed in all patients with systemic brucellosis.

Association of Serum Krebs von den Lungen-6 (KL-6) Levels and Disease Severity in Patients Hospitalized with COVID-19.

Objective: We aimed to evaluate Krebs von den Lungen-6 (KL-6) as a possible biomarker in determining disease severity in patients with moderate and severe COVID-19. Materials and Methods: This cross-sectional study included moderate or severe COVID-19 patients; critically ill patients who were followed up in the intensive care unit were not included. KL-6 level and routine laboratory test measurements were performed on the first day of admission. The patients were also categorized according to their hyperinflammatory state. Results: The study included 92 patients, 56 (61%) women. The National Institutes of Health (NIH) score was 2 in 52.2% of the patients and 3 in 47.8%. KL-6 levels did not significantly differ in disease severity (NIH score 2 vs. 3; p=0.15). Median KL-6 values were 52.7 (29.1) in patients with <2 COVID-19 hyperinflammatory syndrome score (cHIS) and 61.7 (32.2) in patients with cHIS ≥ 2 (p= 0.077). KL-6 values tended to be higher among the patients with lower lymphocyte counts, but the difference was not statistically significant (<1000 mm³/L p=0.006 and higher cHIS scores ≥2 p=0.07). KL-6 values were also higher in the patients with diabetes mellitus compared to the remaining patients (p =0.036). Conclusion: There was no significant association between the serum KL-6 measured at admission and the severity of COVID-19.

The Evaluation of Cases with Ocular Complications due to Bacillus Calmette-Guerin (BCG) Treatment using the Pool Analysis Method.

OBJECTIVE: The aim of this study was to investigate cases with ocular complications associated with intravesical BCG therapy in terms of clinical features, demographic features and type of ocular involvement. METHODS: PubMed database was scanned for relevant publications using the keywords. Thirty-seven publications and 147 reported cases were identified related to the development of ocular complications due to intravesical BCG treatment. RESULTS: As a result of the analysis performed according to eye involvement, there were 17 cases of conjunctivitis, 7 uveitis, and 5 endophthalmitis. Only 27 (18.3%) cases were of primary ocular involvement and Reiter's syndrome was present in 120 (81.6%) of all cases. CONCLUSIONS: Most of the side-effects of BCG therapy are minor and of short duration. Although rare, it has been reported that potentially serious ocular complications can develop after treatment. Physicians must keep these facts in mind and be alert to the development of ocular symptoms following BCG therapy.

Antibiotic Use among Patients Hospitalized with COVID-19 and Treated in Three Different Clinics.

Objective: In this study, we aimed to determine and compare the rates of empirical antibiotic use and duration between the chest diseases clinic (CDC), infectious disease clinic (IDC), and internal medicine clinic (IMC) among patients hospitalized because of COVID-19. Methods: This cross-sectional study was performed in a single university hospital. The study included all patients aged 18 years and older hospitalized with a PCR-confirmed COVID-19 between May 30, 2021, and August 30, 2021. Clinical and laboratory findings were recorded from the electronic medical records database. Results: The study included a total of 581 inpatients, of whom 310 (53.4%) were women. Of the 581 patients, 475 (81.8%) were prescribed antibiotics. The rate of antibiotic prescription was 71.6% for IDC, 88.5% for CDC, and 87.4% for IMC. The most commonly used antibiotic was moxifloxacin in all groups. The mean treatment duration was 8.9±6.16 days. The mean duration of antibiotic treatment was 11.1±5.90 days for CDC, 11.3±6.74 days for IMC, and 5.3 days±3.76 for IDC. Conclusion: Patients with COVID-19 who were treated in IDC had a lower rate and shorter duration of antibiotic use compared to the other clinics. However, the rate of antibiotic prescription in all three groups was very high. Therefore, antimicrobial management programs should be meticulously conducted to reduce unnecessary antibiotic use.

Syphilis seroprevalence among HlV-infected males in Istanbul, Turkey / Seroprevalencia de la sífilis entre hombres infectados con el HIV en Estambul, Turquía

Abstract Syphilis has become a serious issue for human immunodeficiency virus (HIV)-infected patients worldwide in recent years; however, the studies related to HIV coinfection and syphilis reinfections in Istanbul, Turkey, are limited. Ourobjective was to determine the seroprevalence of syphilis among HIV-infected men in the city which has one of the highest HIV prevalence rates in Turkey. Two hundred and forty four (244) HIV-positive men were evaluated at Istanbul Medical Faculty, Department of Medical Microbiology from March to June 2018. Serum samples were screened for the presence of antibodies against Treponema pallidum using the chemilumines-cent microparticle immunoassay (CMIA). Samples found to be positive were investigated with the rapid plasma reagin (RPR) test and the T. pallidum hemagglutination assay (TPHA). The patients completed a questionnaire for sociodemographic data. The mean age was found to be 41.8 years; 35.6% were men who havesexwith men (MSM). The overall seroprevalence of syphilis among the patients was 19.3%. MSM had a significantly higher seroprevalence than heterosexual patients (28.7%). In Turkey, there is a high seroprevalence of syphilis in HIV-infected patients, MSM being the most affected group. Therefore, HIV-infected patients should be screened for syphilis at least annually and should be informed about sexually transmitted diseases (STDs).

Resumen En los últimos años, la sífilis se ha convertido en un problema grave para los pacientes infectados por el virus de la inmunodeficiencia humana (HIV) en todo el mundo; sin embargo, los estudios relacionados con la coinfección por HIV y las reinfecciones por sífilis en Estambul, Turquía, son limitados. Nuestro objetivo fue determinar la seroprevalencia de la sífilis entre los hombres infectados por el HIV en Estambul, ciudad con las tasas de prevalencia del HIV más altas de Turquía. Se evaluaron 244 hombres con HIV entre marzo y junio de 2018 en la Facultad de Medicina de Estambul, Departamento de Microbiología Médica. Las muestras de suero se analizaron para detectar la presencia de anticuerpos contra Treponema pallidum con un inmunoensayo de micropartículas quimioluminiscentes (CMIA). Las muestras que resultaron positivas en dicha prueba se investigaron con la prueba de reagina plasmática rápida (RPR) y el ensayo de hemoaglutinación T. pallidum (TPHA). Los pacientes completaron un cuestionario de datos sociodemográficos. La media de la edad fue de 41,8 anos; 35,6% eran hombres que tienen sexo con hombres (HSH). La seroprevalencia global de sífilis entre los pacientes fue del 19,3%. Los HSH tuvieron una seroprevalencia significativamente mayor que los pacientes heterosexuales (28,7%). En Turquía, existe una alta seroprevalencia de la sífilis en pacientes infectados por el HIV y los HSH son el grupo más afectado. Por lo tanto, los pacientes infectados por el HIV deben someterse a la detección de sífilis al menos una vez al año y deben ser informados sobre las enfermedades de transmisión sexual (ETS).
