Abstract
Objective Each year, approximately 125 million people visit malaria-endemic countries. This study aimed to investigate the clinical characteristics of imported Plasmodium falciparum malaria infections in Türkiye. Methods The study included patients diagnosed with P. falciparum malaria between 1996 and 2022. A retrospective evaluation was conducted on whole blood samples and/or blood smears, as well as detailed medical histories, clinical manifestations, and laboratory findings. A total of 131 imported cases of P. falciparum were included in the study. Results Among the patients, 121 were male. Of these, 101 had traveled to Africa, while 30 had visited Asia. Among the patients, 109 were returned travelers, and 22 were refugees/migrants. Early trophozoites were observed in all patients, while gametocytes were detected in 30 patients. Cerebral malaria developed in 15 patients, resulting in the death of two individuals. Additionally, 10 patients received preventive chemoprophylaxis. Conclusion Turkey is situated on migration routes that connect two continents to Europe, where more than 95% of the global malaria burden exists. The importation of malaria through returned travelers poses a risk of malaria reintroduction in our country, given the presence of suitable vectors, climate conditions, and environmental factors. Importantly, 30 patients (22.9%) exhibited gametocyte forms of P. falciparum, which have the potential to infect Anopheles species, thus establishing a basis for local malaria transmission.

Abstract
This study examines the risk of malaria, leishmaniasis, and scabies following earthquakes in southeastern Türkiye. The focus is on the impact on the local population and Syrian immigrants. Recommendations for prevention include vector control measures such as indoor residual spraying and distribution of insecticidal nets. Surveillance and early detection through rapid diagnostic tests and active case finding are important. Public awareness campaigns and community engagement are crucial for promoting protective measures. Strengthening healthcare infrastructure, providing essential supplies, and capacity building is essential. For leishmaniasis, early detection and treatment, vector control, health education, and community engagement are vital. Scabies outbreaks affect the socioeconomically depressed local population and Syrian immigrants. Early detection, treatment, contact tracing, health education, hygiene promotion, and improved living conditions are necessary. Implementing these interventions and strategies can effectively prevent, control, and manage these diseases. Tailoring approaches to the specific context and needs of affected communities is crucial. By addressing these challenges, we can protect the health and well-being of the affected population.

Knock, knock, knocking on Europe 's door: Threat of leishmaniasis in Europe with a focus on Turkey. CURRENT RESEARCH IN PARASITOLOGY & VECTOR-BORNE DISEASES 2023; 4:100150. [PMID: 37941928 PMCID: PMC10628545 DOI: 10.1016/j.crpvbd.2023.100150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 10/03/2023] [Accepted: 10/10/2023] [Indexed: 11/10/2023]
Abstract
Leishmaniasis epidemiology is currently undergoing substantial transformations in both Turkey and Europe, signifying potential implications for public health. This review analyzes the evolving patterns within Turkey and their potential ramifications for Europe. Within Turkey, the dynamics of leishmaniasis are undergoing noteworthy alterations, manifesting in a rise in cutaneous leishmaniasis (CL) cases and the emergence of Leishmania major and Leishmania donovani. These transformations are predominantly driven by factors such as the distribution of vectors, human activities, climate fluctuations, and migration. Across Europe, particularly in countries within the Mediterranean basin, leishmaniasis is endemic, primarily attributed to Leishmania infantum. Recent evidence suggests a resurgence of the disease even in previously non-endemic areas, propelled by climate change, urbanization, and migration. The changing landscape of leishmaniasis in Turkey carries direct implications for Europe. The presence and distribution of Leishmania tropica, L. major, and L. donovani raise concerns regarding cross-border transmission. Turkey's strategic position along migration routes further compounds the risk, alongside the facilitative effects of climate change and host mobility. Embracing a One Health approach with public awareness campaigns should be a priority. To ensure the protection of public health in Europe, it is imperative to adopt a proactive approach by establishing robust surveillance mechanisms, implementing preventive measures, and cultivating collaboration with Turkey. The invaluable experience, strategic geographical location, and well-established infrastructure of Turkey make this collaboration crucial in effectively addressing the evolving dynamics of leishmaniasis and its potential impacts on Europe.

Visceral Leishmaniasis Caused by Leishmania Tropica. Acta Parasitol 2023; 68:699-704. [PMID: 37351773 DOI: 10.1007/s11686-023-00695-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Accepted: 06/07/2023] [Indexed: 06/24/2023]
Abstract
PURPOSE In Turkey, the main causative agent of visceral leishmaniasis (VL) is Leishmania. infantum and the main causative agent of cutaneous leishmaniasis (CL) is Leishmania tropica. In this study, we aimed to discuss the possible mechanisms, clinical aspects, and threat of visceralizing L. tropica. METHODS This study includes seven cases of VL caused by L. tropica.Five patients were male (71%) and four were adults (57%). RESULTS All the VL patients complained of fever and splenomegaly. Fatigue, pancytopenia, and hepatomegaly were present in six patients each (86%), while weight loss and gastrointestinal system (GIS) symptoms were present in 5 patients (71%). CONCLUSIONS In this study, we have evaluated seven cases of visceralized L. tropica (VLT) in the context of the changing leishmaniasis epidemiology in Turkey. We have evaluated the possible mechanisms of visceralization; inter- and intraspecies genetic exchange with all the old world leishmaniasis agents present in the region, stress induced by inappropriate use of drugs, and possible ongoing adaptation mechanisms of Leishmania spp. The threat posed by VLT is significant as L. tropica is the most widespread and most common cause of leishmaniasis in Turkey. We do not know the vectorial capacity of the sand flies for the transmission of VLT strains or if these strains are in circulation in Turkey. Future studies should be carried out to investigate these issues as the transition of L. tropica from a mild disease-causing agent to a mortal one poses a significant public health concern for Turkey and Europe.

Autochthonous transmission of Leishmania donovani and Leishmania major with all the components of infection cycle at Europe's doorstep. Acta Trop 2022; 230:106385. [PMID: 35245491 DOI: 10.1016/j.actatropica.2022.106385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/20/2022] [Accepted: 02/22/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVES Leishmaniasis is a vector-borne disease and dogs may act as urban reservoirs. Turkey and most of the Mediterranean basin countries are endemic for leishmaniasis. In this study, it is aimed to report the autochthonous leishmaniasis cases, with all the components of the infection cycle (reservoir, vector, and the host) in a region close to Europe. METHODS Nine human and four canine autochthonous leishmaniasis cases were included in the study. Direct microscopy, culture methods, serological, and molecular tests were applied to the samples obtained from the cases. RESULTS VL and CL patients consisted of 2 L.infantum, 1 L. donovani, 2 L. tropica, and 2 L. tropica,1 L. major,1 L. infantum infected patients respectively. CanL cases were infected with L. infantum, L. donovani, L. tropica, and L. major. CONCLUSIONS All the cases were autochthonous cases located in Manisa province. As Greece and all the Mediterranean basin countries in Europe share competent vectors, it is concluded that the detection of all 4 species of Leishmania parasites in such proximity to Europe poses an important public health threat for Europe. This study reports all four species of Leishmania spp., including L. major and L.donovani in close proximity to continental Europe.

Abstract
OBJECTIVE Leishmaniasis is the second deadliest parasitic disease in the World Health Organisation's list of neglected diseases, following malaria. Cutaneous leishmaniasis (CL) is the most common form of the disease and it is one of the few communicable diseases with increasing incidence rates owing to factors like armed conflicts and climate change. CL can be divided into two major groups: Acute CL (ACL) and chronic CL (CCL). The aim of this study was to compare the in vitro efficacy of miltefosine and pentavalent antimony compounds in the CCL patient samples. METHODS Five isolates previously isolated from 5 CCL patients were included in this study. Genotyping is performed using internal transcribed spacer 1 (ITS 1) gene region real-time PCR. In vitro drug efficacy tests were applied to determine their activity against meglumine antimoniate (MA) and miltefosine. Serial dilutions (512, 256, 128, 64, 32, 16, 8 and 4 µg/mL) prepared from MA and miltefosine were prepared in 96-well flat-bottom cell culture plates and incubated at 24 °C for 48 hours. The efficacy of the drug on Leishmania spp. promastigotes after 24 and 48 hours was evaluated by hemocytometer slide and XTT cell viability test. RESULTS All of the samples were genotyped as L. tropica. Evaluation of 24 and 48 hours showed, 128 µg/mL and 256 µg/mL and 32 µg/mL and 64 µg/mL concentrations of miltefosine and MA were enough to kill all the promastigotes respectively. The results of the hemocytometer slide and XTT were consistent. CONCLUSION There are no studies investigating the in vitro efficacy of miltefosine with the CCL patient group. To overcome the treatment challenges experienced in this special patient group, more studies are needed. According to our results, it is concluded that miltefosine is efficient for the treatment of CCL and further clinical studies with miltefosine will reveal valuable data.

Abstract
OBJECTIVE This study aimed to assess the attitudes and awareness of medical doctors practicing in Turkey about the discipline of travel medicine (TM). METHODS This study was a cross-sectional survey conducted via the internet for 1 month between January 10, 2020 and February 10, 2020. The study participants were medical students or graduated medical doctors. The questionnaire used for the survey was broadly structured to measure participants' education on TM, perception of TM, and general knowledge about TM. RESULTS A total of 502 participants were included in the study, of which 188 (37.4%) were medical students and 314 (62.6%) were medical doctors. Forty-nine out of 82 (60%) medical faculties' students or graduates took part in this study. Experience in medicine was significantly associated with education and perception of TM but not with general knowledge about TM. CONCLUSION Our data indicate that medical doctors in Turkey are not familiar with the discipline (60%) and that the medical doctors believe that the importance of TM is increasing (58.4%). In total, 93.2% participants believe that social awareness about TM is insufficient. A total of 69% participants believe that infectious diseases make up the bulk of TM. To the best of our knowledge, this study is the first study to assess the awareness and attitudes of medical doctors in Turkey about TM.

Abstract
Intestinal protozoan parasites are common causes of infectious diarrhea in children receiving anticancer therapy or undergoing transplantation. Additionally, immunosuppression therapy in such patients may exacerbate the symptoms related to these parasitic infections. The aim of this study was to evaluate the prevalence and diagnostic importance of parasitic protozoan infections in children treated for malignancies or undergoing transplantation, and to highlight the control of intestinal parasitic infections for immunosuppressed patients at a hospital in İzmir, Turkey. In total, 82 stool samples from 62 patients were analyzed by microscopic examination and polymerase chain reaction (PCR) for the presence of coccidian parasites. Our results showed that Cryptosporidium, Cyclospora, and Cystoisospora were present in 22.5% (14/62), 9.6% (6/62), and 3.2% (2/62) of the cases using either method, respectively. The prevalence of these coccidian parasites identified with both methods was 35.4% (20/62). Other intestinal parasites (Blastocystis, Giardia, and Entamoeba coli) were detected in 10 patients. PCR analysis showed the presence of all coccidian parasites in the same stool sample for one patient. Finally, both PCR and microscopic examination of the stools revealed that there is a higher prevalence of Cryptosporidium, Cyclospora, and Cystoisospora in immunocompromised children. These examinations allowed an early start of appropriate antibiotic treatments and led to an increased percentage of correctly treated patients.

Abstract
OBJECTIVE Blastocystosis has been linked with non-specific symptoms, such as diarrhea, abdominal pain, and distention. In this study, we evaluated the relationship between Blastocystis spp. with urticaria and intestinal symptoms. METHODS The results of the stool examinations of the patients who were referred to Ege University Medical Faculty Hospital's Medical Parasitology Department Direct Diagnosis Laboratory with gastrointestinal (GIS) and/or dermatologic symptoms between January 2011 and July 2016 were retrospectively scanned. RESULTS Of the evaluated 37108 stool samples, 2573 (6.93 %) were identified to be positive for Blastocystis spp. The patients with gastrointestinal complaints comprised 68.4% of Blastocystis spp. positive samples (1.761 samples) while 30.1% of patients had dermatologic symptoms (urticaria) (776 samples). Blastocystis spp. density in the non-amplified (without using any stool concentration technique) stool samples of the patients with GIS and dermatological symptoms was as follows: 2.47%, 1.35% rare, 21.73%, 22.17% few, 49.65%, 54.29% medium, 26.27%, and 22.17% dense, respectively. CONCLUSION 75.92% and 76.46% of the patients with GIS and dermatological complaints had medium to dense parasite densities in their stool samples respectively. This suggests a positive correlation between parasite density and GIS and dermatologic symptomatology.

Abstract
OBJECTIVE Intestinal parasitic infections are common in immunodeficient patients. In developing countries, the incidence of diarrhea due to parasitic infections in HIV (human immunodeficiency virus)-positive individuals is reported to be over 90%. The present study aimed to investigate the presence of intestinal protozoa in HIV-positive patients with gastrointestinal complaints. METHODS The fecal samples of 65 HIV-positive patients (14 women, 51 men) were included. Clinical data obtained from patients' files and laboratory results were retrospectively scanned using laboratory information system. Age, sex, parasite positivity, CD4+ count, HIV RNA level, and antiretroviral therapy information were recorded. RESULTS Fourteen Cryptosporidium spp. (21.5%), 2 Cyclospora spp. (3.1%), 7 Blastocystis spp. (10.8%), and 1 Cryptosporidium spp.+Blastocystis spp. (1.5%) were detected. The median duration of antiretroviral treatment was 3 months and 12 months in patients with and without parasites in fecal samples, respectively. The duration of antiretroviral treatment was significantly higher in non-infected patients (p=0.002). No significant correlations were found between parasite presence and CD4+ T cell counts or HIV RNA levels. CONCLUSION Our findings suggest that positive effects of antiretroviral therapy on the immune system of HIV-infected patients reduce the risk of intestinal parasitic infection, and thus, this treatment may play an important role in protection.

Abstract
The most common types of malaria in the world are Plasmodium vivax and P. falciparum. In countries where both species are endemic, P. vivax and P. falciparum coinfection also occurs. Thus, the possibility of mixed malaria in Turkey should always be considered in cases with a traveling history to these countries. Here, we report a case of P. vivax/P. falciparum mixed infection that was diagnosed as P. falciparum malaria in Ethiopia. However, the administered treatment was inadequate, and infection recurred because of the miss in the diagnosis of P. vivax malaria, for which an effective drug for hypnozoites was not administered. This case report emphasizes the importance of diagnosis, correct and adequate treatment of infections, and a close follow-up of diseases.

Abstract
Leishmaniasis is a vector-borne zoonotic disease that shows different clinical features like cutaneous, mucocutaneous, visceral and viscerotropic forms. The protocols used in the treatment of leishmaniasis are toxic and have many limitations during administration. One of the limitations of treatment is the resistance against the protocols in practice. There is also a need to define new treatment options especially for resistant patients. Ex-vivo models using primary cell cultures may be a good source for evaluating new drug options in patients with antimony resistance, in addition to in-vitro and in-vivo studies. In this study, it was aimed to define a new ex-vivo culture model to evaluate treatment options in patients with cutaneous leishmaniasis who did not respond to treatment. In our experimental model of ex-vivo infection, Leishmania tropica promastigotes isolated from a case previously diagnosed with cutaneous leishmaniasis were used. The primary astroglial cell culture used for the ex-vivo model was prepared from 2-3 days old neonatal Sprague Dawley rat brains under sterile conditions by the modification McCarthy's method. The astroglia cells, which reached sufficient density, were infected with antimony resistant L.tropica promastigotes. After 24 hours of incubation, the supernatant on the cells were collected, the cell culture plate was dried at room temperature, then fixed with methyl alcohol and stained with Giemsa to search for L.tropica amastigotes. Amastigotes were intensely observed in glia cells in primary cell cultures infected with L.tropica promastigotes. No promastigotes were seen on Giemsa stained preparations of the precipitates prepared from the bottom sediment after the centrifugation of the liquid medium removed from the infected plates. In this study, promastigotes from a cutaneous leishmaniasis patient unable to respond to pentavalent antimony therapy were shown to infect rat glia cells and converted to amastigote form. This amastigote glial cell model, as far as we know, is the first model in the literature produced by L.tropica. The occurrence of L.tropica amastigote forms in glia cells may be indicative of the ability of Leishmania species to infect the central nervous system. The central nervous system may be an area for the Leishmania amastigotes to escape from the immune system in cases of leishmaniasis without a treatment response. Our study is important because it is the first study to show the infection of glia cells with L.tropica amastigotes.

Abstract
Travel medicine defines all diseases and medical situations that are related to travel. Travel medicine comprises infectious diseases, traumas, altitude sickness, sun burns, embolisms, jet lag, and many more travel-related situations. With the increasing possibility and ease of travel, the number of people who have travelled internationally has exceeded 1.13 billion in 2014, and the revenues of international travel have exceeded 1.25 trillion dollars. With every passing day, international travels are shifting toward the developing countries and to more exotic regions of the world, and travelers tend to be more adventurous and daring, thereby increasing risky behaviors during travels. Traveling plays an important role in transmitting infections such as Zika virus infection, Ebola, avian flu, severe acute respiratory syndrome, Chikungunya, and dengue fever and is the principal reason for the epidemics of these types of infections on a global scale. With this background, we suggest that travel medicine is an important but "neglected" medical discipline as the discipline of Parasitology itself like most parasitic diseases.

Abstract
OBJECTIVE Parasites might cause atypical and severe infections in immunocompromised hosts. The prevalence of diarrhea among common variable immune deficiency (CVID) syndrome patients varies between 20% and 94%, which indicates that diarrhea and gastrointestinal system (GIS) complaints could be the second leading cause of morbidity in CVID patients after respiratory tract infections. This study aimed to assess the prevalence of intestinal parasites in CVID patients with GIS complaints and diarrhea. METHODS In this study, all cases followed up in the Immunology and Allergy Clinic of Ege University School of Medicine from July 2008 to August 2015 with the diagnosis of CVID were reviewed retrospectively. The stool samples of patients with diarrhea were identified using direct microscopy of native (0.09% NaCl) and Lugol's iodine preparations followed by formol-ethyl acetate concentration to apply modified Kinyoun, trichrome, acid-fast trichrome, and modified trichrome stains for the presence of intestinal parasites. RESULTS Overall, 26 of 37 CVID patients had diarrhea; white and red blood cells (WBCs and RBCs, respectively) were identified in 11 and 10 of these 26 samples, respectively. Intestinal parasites were found to be present in 7 of the 11 patients with WBCs and 3 of the 10 patients with RBCs. With the addition of patients who neither had WBCs nor RBCs in their stool, a parasitic agent was detected in 13 (50%) of the 26 patients with diarrhea. There was no significant difference between the diarrheic patients with or without intestinal parasites with respect to cramps, fever, nausea and vomiting, tenesmus, bloody feces, and presence of mucus in the stool. Only one patient had malabsorption, which was not associated with intestinal parasites. The most common parasites detected in this study were Cryptosporidium spp. (n=9; 69.2%), Giardia spp. (n=7; 53.8%), and Blastocystis spp. (n=3; 23.1%). We also identified that parasitic diarrhea in CVID patients tended to last longer (M (mean): 16.2 days) than other causes of infectious diarrhea; this is in accordance with previous studies. CONCLUSION Cryptosporidium spp. was found be the major cause of parasitic intestinal infection in this patient population. It was concluded that parasitic infections may cause chronic diarrhea, which are major causes of morbidity in CVID patients. Therefore, special attention is necessary for the identification of intestinal parasites in CVID patients with diarrhea.
