13. Challenging Management of Hepatitis B infection in Ankylosing Spondylitis Patients in an Endemic Area during Immunosuppressive Therapy
Abstract Hepatitis B infection is a global health issue. When considering patients with rheumatic diseases, this is no different. By using immunosuppressant drugs, such as DMARDs and biologics, viral reactivation is possible, leading to serious consequences on the patient. We report 3 cases of association between ankylosing spondylitis and hepatitis B with t

14. Circulation of spotted fever group rickettsiae among dogs seropositive for Leishmania spp. in an urban area of Brazil
Abstract INTRODUCTION: Dogs play an epidemiological role in several vector-borne diseases that affect human and animal health worldwide. We aimed to identify rickettsial circulation among dogs with canine visceral leishmaniasis (CVL) from a region endemic for both diseases. METHODS: CVL-seropositive dogs were screened for spotted fever group rickettsiae

15. Nanoparticulate drug delivery systems for the treatment of neglected tropical protozoan diseases
Abstract Neglected Tropical Diseases (NTDs) comprise of a group of seventeen infectious conditions endemic in many developing countries. Among these diseases are three of protozoan origin, namely leishmaniasis, Chagas disease, and African trypanosomiasis, caused by the parasites Leishmania spp., Trypanosoma cruzi, and Trypanosoma brucei respectively. These d

16. Fatal case of spotted fever in a patient from Northeastern Brazil
ABSTRACT Spotted fevers are diseases caused by bacterial agents belonging to the spotted-fever (SF) group of the genus Rickettsia. The first documented case of SF in Pernambuco State, Northeast Brazil, was reported here. Also, it is the first case described of fatal SF in Northeast region of Brazil. The patient was a resident of Arcoverde municipality and th

17. Chagas disease and systemic autoimmune diseases among Bolivian patients in Switzerland
BACKGROUND Chronic cardiomyopathy occurs in 20-40% of the patients with Chagas disease. Autoimmune mechanisms may contribute to its pathogenesis. We diagnosed several cases of systemic autoimmune diseases among Bolivian migrants in Geneva with a high prevalence of Chagas disease. OBJECTIVES We tested the hypothesis of a clinical association between systemi

18. Synthesis of 3,5-Diarylisoxazole Derivatives and Evaluation of in vitro Trypanocidal Activity
Chagas disease is included in the neglected tropical diseases list and is endemic to 21 Latin American countries. The two drugs currently available for treating Chagas disease are nifurtimox and benznidazole and both result in many significant side effects. The study describes the synthesis and biological evaluation of 3,5-disubstituted isoxazoles. Isoxazole

19. Environmental suitability for Lutzomyia longipalpis in a subtropical city with a recently established visceral leishmaniasis transmission cycle, Argentina
BACKGROUND Visceral leishmaniasis (VL) is an endemic disease in northeastern Argentina including the Corrientes province, where the presence of the vector and canine cases of VL were recently confirmed in December 2008. OBJECTIVES The objective of this study was to assess the modelling of micro- and macro-habitat variables to evaluate the urban environme

20. Sandfly fauna (Diptera: Psychodidae) in an urban area, Central-West of Brazil
ABSTRACT Biological and ecological relations among vectors and their pathogens are important to understand the epidemiology of vector-borne diseases. Camapuã is an endemic area for visceral and tegumentary leishmaniasis. The aim of this study was to characterize the sandfly fauna present in Camapuã , MS, Brazil. Sand flies were collected every fortnight fr

21. Secondary Metabolites from an Infusion of Lippia gracilis Schauer Using the LC-DAD-SPE/NMR Hyphenation Technique
The genus Lippia comprises approximately 200 species of herbs, shrubs and small trees, distributed throughout the South and Central America and tropical Africa. The species Lippia gracilis Schauer is an endemic aromatic plant of the Brazilian Northeast normally found in the states of Bahia, Sergipe and Piauí. The traditional communities of Caatinga, a semi-

22. A tale of two neglected tropical infections: using GIS to assess the spatial and temporal overlap of schistosomiasis and leprosy in a region of Minas Gerais, Brazil
BACKGROUND Despite public health efforts to reduce the global burden of leprosy, gaps remain in the knowledge surrounding transmission of infection. Helminth co-infections have been associated with a shift towards the lepromatous end of the disease spectrum, potentially increasing transmission in co-endemic areas. OBJECTIVES Using this biologically plaus

23. Pharmacobotanical study of Hypericum thymopsis
ABSTRACT Hypericum thymopsis Boiss., Hypericaceae, is an endemic herb which generally grows at the calcareous steppe regions of Central Turkey. In flowering stage, the aerial parts of this species are used for wound-healing and sedation, and its infusions are used against stomach diseases and throat infections by local people. The aim of this study, to exami

24. Concordance between IFNγ gene +874 A/T polymorphism and interferon-γ expression in a TB-endemic indigenous setting
Abstract INTRODUCTION: Interferon-γ (IFN-γ) plays a crucial role in resistance to mycobacterial diseases; accordingly, variants of the gene encoding this cytokine may be associated with elevated risk of contracting pulmonary tuberculosis (TB). METHODS: Blood samples were collected from 135 Warao indigenous individuals with newly diagnosed sputum culture
