RESUMO
Adults living with HIV (human immunodeficiency virus) infection (ALHIV) have high rates of cardiovascular events. New approaches are needed to detect subclinical cardiac dysfunction. We used conventional and speckle tracking echocardiography to investigate whether ALHIV display latent cardiac dysfunction. We analyzed 85 young subjects with HIV infection and free from cardiovascular risk factors (31 ± 4 years) and 80 matched healthy volunteers. We measured left ventricular (LV) layered global longitudinal strain, circumferential strain, peak longitudinal strain in the reservoir and contraction phases of the left atrium (LASr respectively LASct). In the HIV group, LV ejection fraction and s' TDI (tissue doppler imaging) were slightly lower but still in the normal ranges. Layered longitudinal strain showed no significant difference, whereas circumferential global strain was significantly lower in the HIV group (−20.3 ± 3.9 vs. −22.3 ± 3.0, p < 0.001). LASr (34.3% ± 7.3% vs. 38.0% ± 6.9%, p < 0.001) was also lower in ALHIV and multivariate analysis showed that age (ß = −0.737, p = 0.01) and infection duration (ß = −0.221, p = 0.02) were independently associated with LASr. In the absence of cardiovascular risk factors, adults living with HIV display normal LV systolic function. Left atrial reservoir strain, is, however, decreased and suggests early diastolic dysfunction.
RESUMO
Lemierre's syndrome is, presently, a very rare condition, but a life-threatening one. The syndrome was first described in 1936 by Andre Lemierre and comprises an oropharyngeal infection (most commonly associated with anaerobic bacteria Fusobacterium necrophorum), internal jugular vein thrombophlebitis and, possibly, secondary septic metastasis (common sites are lungs or brain). We describe such a rare case diagnosed at our Infectious Diseases Department in September 2019.
