Case report: acute portal vein thrombosis associated with acute cytomegalovirus infection in an immunocompetent adult
2017
Cytomegalovirus (CMV) infection is usually asymptomatic and self-limiting in healthy individuals, but significant complications can develop in immunosuppressed patients. Venous or arterial thromboembolic phenomena are uncommon yet very serious complications of CMV infection. Most published reports describe immunosuppressed patients, but thrombotic events in CMV-infected immunocompetent individuals may also occur. We describe the case of an immunocompetent young man with acute CMV hepatitis that was complicated with portal vein thrombosis (PVT). We also review the literature regarding the association between PVT and CMV in immunocompetent patients. Thromboembolism is an underestimated but si…
What Could Be a Primary Cause of Multiple Sclerosis: Is It an Autoimmunity Triggered by Chronic Protozoan Infection?
2013
The generally accepted paradigm of multiple sclerosis is the autoimmune one; still, a body of evidence suggests that this disease may actually be triggered by an infectious factor. In this paper, it is hypothesized that multiple sclerosis may actually be a rare complication of a protozoan infection, which is usually asymptomatic but in some susceptible individuals is accompanied by autoimmune attack against the nervous tissue. If multiple sclerosis were actually caused by such an infection, then a microorganism responsible should exhibit several properties: it (i) is transmitted by an arthropod vector; (ii) is characterized by specific metabolism of the lipids; (iii) should be dependent on …
