Low blood pressure is a frequently encountered phenomenon in clinical practice. Few practitioners in the Western world however regard chronic low blood pressure as a genuinely pathological disease state. Evidence is emerging that chronic hypotension is associated with considerable morbidity in the community. It has recently been implicated as the causative mechanism in patients with the chronic fatigue syndrome. Identification of low blood pressure can prove probjlematic, so ambulatory blood pressure monitoring may prove a more reliable method both for determining mean blood pressure levels and for identifying episodes of marked hypotension. Low blood pressure is broadly divided into two categories, chronic constitutional hypotension and hypotension associated with abnormal postural control. The causes are examined and the clinical presentations are discussed. An approach to investigation and diagnosis is outlined, and current options regarding treatment and management are described. The clinical spectrum of low blood pressure is wide. From young patients with vagally mediated syncope or patients with iatrogenic hypotension to elderly patients with autonomic degenerative conditions, there exists a substantial body of patients with potentially avoidable or treatable morbidity. Such a group requires more rigorous scientific investigation and a more sympathetic clinical approach.

Background Many natural compounds were tested for the ability to suppress viral replication. The present manuscript details an analysis of high dose vitamin C therapy on patients with EBV infection. Material and Methods The data were obtained from the patient history database at the Riordan Clinic. Among people in our database who were treated with intravenous vitamin C (7.5 g to 50 g infusions) between 1997 and 2006, 178 patients showed elevated levels of EBV EA IgG (range 25 to 211 AU) and 40 showed elevated levels of EBV VCA IgM (range 25 to 140 AU). Most of these patients had a diagnosis of chronic fatigue syndrome, with the rest being diagnosed as having mononucleosis, fatigue, or EBV infection. Results Our data provide evidence that high dose intravenous vitamin C therapy has a positive effect on disease duration and reduction of viral antibody levels. Plasma levels of ascorbic acid and vitamin D were correlated with levels of antibodies to EBV. We found an inverse correlation between EBV VCA IgM and vitamin C in plasma in patients with mononucleosis and CFS meaning that patients with high levels of vitamin C tended to have lower levels of antigens in the acute state of disease. In addition, a relation was found between vitamin D levels and EBV EA IgG with lower levels of EBV early antigen IgG for higher levels of vitamin D. Conclusions The clinical study of ascorbic acid and EBV infection showed the reduction in EBV EA IgG and EBV VCA IgM antibody levels over time during IVC therapy that is consistent with observations from the literature that millimolar levels of ascorbate hinder viral infection and replication in vitro.
