Podagra is a term used to describe acute monoarthritis of the first metatarsophalangeal (1st MTP) joint. The most common diagnoses of arthritis in this joint are: crystal-induced synovitis, septic arthritis, traumatic conditions and reactive arthritis. When etiologies other than gout are involved this is frequently referred to as pseudopodagra. We report the case of a patient who presented with pain and swelling of the 1st MTP The absence of intraarticular crystals and hyperuricemia encouraged further evaluation of the patient. A cardiac murmur was investigated by echocardiography, which revealed valvular vegetations and the diagnosis of infective endocarditis (IE) was established. This is the first reported case of a podagra-like presentation of IE. As in this case, the diagnosis of gout should rest on findings beyond the presence at 1st MTP arthritis, with evaluation of all extraarticular signs in order to rule out other possible diagnoses.

Metabolic syndrome (MetS) is a cluster of risk factors, including elevated mean arterial pressure (MAP), atherogenic dyslipidemia (elevated triglycerides [TRG]), abdominal obesity (increased body mass index [BMI]), glucose intolerance (elevated glucose [GLU]), and prothrombotic/inflammatory state (increases in uric acid [UA]), that are associated with increased risk of cerebrovascular disease. We studied if an association existed between MetS components and human immunodeficiency virus (HIV)-associated cryptogenic strokes-those not caused by HIV complications, endocarditis, or stimulant abuse. We performed a retrospective case-control study. Eleven cryptogenic strokes were identified from 2346 HIV-infected (HIV+) participants. Each case was matched by age, sex, and date of stroke diagnosis to five HIV+ controls without stroke. Nonparametric stratified Wilcoxon ranked sum tests with subsequent mixed effect logistic regression determined the influence of each MetS component on HIV-associated cryptogenic stroke. Although each MetS component appeared higher for HIV+ cases with cryptogenic strokes than HIV+ controls, only MAP (odds ratio [OR] = 5.70, 95% confidence interval [CI] = 1.15-28.3) and UA (OR = 1.88, 95% CI = 1.06-3.32) were statistically different. A significantly higher percentage of HIV-associated cryptogenic stroke cases met criteria for MetS (4/11 = 36%) compared to HIV+ controls (6/55 = 11%). This observational study suggests a possible role for MetS components in HIV+ cryptogenic stroke cases. Although MetS is defined as a constellation of disorders, elevated hypertension and hyperuricemia may be involved in stroke pathogenesis. Reducing MetS component levels in HIV+ patients could therefore protect them from subsequent stroke.
