Human parvovirus B19 infections may cause a widespread benign and self-limiting disease in children and adults, known as erythema infectiosum or fifth disease. A variety of further manifestations are associated with the infection such as arthralgias, arthritis, leukopenia and thrombocytopenia, anemia and vasculitis, spontaneous abortion and hydrops fetalis in pregnant women. Both in children and adults parvovirus B19 infections have been frequently implicated as a cause or trigger of various forms of autoimmune diseases affecting joints, connective tissue and large and small vessels. In addition, autoimmune neutropenia, thrombocytopenia and hemolytic anemia are known as sequelae of B19 infection. The molecular basis of the autoimmune phenomena and resultant pathogenesis is unclear. The involvement of molecular mimicry between cellular and viral proteins, the induction of enhanced cytokine production via the viral transactivator protein NS1 and the phospholipase A2-like activity of the capsid protein VP1 may contribute to the induction of autoimmune reactions. All the known data and the potential mechanisms involved in the pathogenesis will be discussed in this review.

Extremely widespread, the dengue is a reemerging infectious disease. In Burkina Faso, dengue is a reality that was little known. The aim of this study was to study epidemiology, diagnostic and outcomes of dengue patients in Ouagadougou. A retrospective study covered a period of two years, from 1 January 2013 to 31 December 2014 in a private clinic in Ouagadougou. Patients included in the study were hospitalized for fever and painful syndrome with a positive test to the dengue non-structural antigen 1 (NS1 Ag). Ninety-eight cases of dengue on 343 suspected cases were registered. The average age of patients was 35.9 years. The sex-ratio (M/F) was 1.18. According to the professional activity, there was a predominance of civil servants (35.7%). The pain syndrome was found in 93.9% of patients. Leukopenia (73.5%), neutropenia (56.1%) and severe thrombocytopenia (57.1%) were the predominant hematological disturbances. Of the patients, 18.4% had hemorrhagic dengue and 11.2%, a dengue shock syndrome. Four patients died. The use of non-steroidal antiinflammatory drugs was associated with the severity of the infection (p=0.04). Dengue fever occurs in our context and constitutes a risk of mortality. The diagnosis of dengue should be performed systematically in front of a painful and febrile syndrome. The vector control is the best way of prevention against dengue pending the development of a vaccine.
