Arrais, Margarete; Dias, Welwitschia; Silva, Maura; Neto, Luquenia; Pedro, Naiol; Jungo, Sónia; Miguel, Avelina; Fortes-Gabriel, Elsa; Sebastião, CruzBackground: The impact of SARS-CoV-2 infection in Africa is still unclear. In comparison to Europe and North America, morbidity and death rates are lower. Several factors have been proposed, including geographical variation in virus impact, environmental factors, differences in age distribution, and the impact of infectious diseases such as malaria, HIV infection, and tuberculosis. Objectives: We investigated t...

Sebastião, Cruz S.; Cogle, Adis; Teixeira, Alice D’Alva; Cândido, Ana Micolo; Tchoni, Chissengo; Amorim, Maria João; Loureiro, N’guezaBackground: Infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with clinical features of diverse severity. Few studies investigated the severity and mortality predictors of coronavirus disease 2019 (COVID-19) in Africa. Herein, we investigated the clinical features of severity and mortality among COVID-19 patients in Luanda, Angola. Methods: This multicenter cohort study...

Sebastião, Cruz S.; Teixeira, Alice; Luísa, Ana; Arrais, Margarete; Tchonhi, Chissengo; Cogle, Adis; Sacomboio, Euclides; Cardoso, Bruno; Morais, JoanaSARS-CoV-2 is a public health concern worldwide. Identification of biological factors that could influence transmission and worsen the disease has been the subject of extensive investigation. Herein, we investigate the impact of the ABO/Rh blood group on susceptibility and severity among COVID-19 patients in Luanda, Angola. This was a multicentric cohort study conducted with 101 COVID-19 patients. Chi-square an...
Helminth infections and allergic diseases: systematic review and meta-analysis ...
Arrais, Margarete; Maricoto, Tiago; Nwaru, Bright I.; Cooper, Philip J.; Gama, Jorge M.R.; Brito, Miguel; Taborda-Barata, LuisBackground: There is considerable research interest in the role of helminth infections in the development of allergic diseases. However, findings from previous studies are mixed. Existing systematic reviews of these studies are outdated. We performed a systematic review of the global literature on the association between helminth infections and development and clinical outcomes of allergic diseases. Methods: We...
Lack of consistent association between asthma, allergic diseases, and intestina...
Arrais, Margarete; Lulua, Ofélia; Quifica, Francisca; Rosado-Pinto, José; Gama, Jorge M.; Cooper, Philip J.; Taborda-Barata, Luis; Brito, MiguelEpidemiological studies have shown conflicting findings on the relationship between asthma, atopy, and intestinal helminth infections. There are no such studies from Angola; therefore, we aimed to evaluate the relationship between asthma, allergic diseases, atopy, and intestinal helminth infection in Angolan schoolchildren. We performed a cross-sectional study of schoolchildren between September and November 20...
Helminth infections, atopy, asthma and allergic diseases: protocol for a system...
Arrais, Margarete; Maricoto, Tiago; Cooper, Philip; Gama, Jorge M. R.; Nwaru, Bright I; Brito, Miguel; Taborda Barata, LuisIntroduction: Childhood infections, particularly those caused by helminths are considered to be important environmental exposures influencing the development of allergic diseases. However, epidemiological studies focusing on the relationship between helminth infections and the risk of allergic diseases, performed worldwide, show inconsistent findings. Previous systematic reviews of observational studies publish...

Arrais, Margarete; Lulua, Ofélia; Quifica, Francisca; Rosado-Pinto, José; Gama, Jorge; Brito, Miguel; Taborda-Barata, LuisIntroduction and Objectives: In Africa, few studies of sensitization profiles have been performed in children or adolescents and, in Angola, there are none. The objectives of the present study were to assess the sensitization profile of Angolan schoolchildren and to determine the relationship between that pattern, sociodemographic factors, asthma, and other allergic diseases. Materials and Methods: Cross-sectio...
