Duration of anti-treponemal immunoglobulin M seroreversion after successful syphilis treatment in HIV-positive and -negative patients

Treponemal immunoglobulin M (IgM) antibody detection is currently among serologic tests used for syphilis diagnosis. However, the exact role of these antibodies is unclear. In this retrospective study of 326 (198 HIV positive and 128 negative) patients with early syphilis and positive IgM serology, data were analysed to investigate the time of IgM seroreversion after treatment and correlation with covariate factors. Median time of IgM seroreversion in the study population was 9 months (range 3-84, interquartile range 5-12). No statistically significant difference was observed between HIV-positive and -negative patients. At 12 months, 80.1% of the patients had a negative IgM test. At 6 months, 100% of HIV-positive patients had a fourfold decrease or greater in Venereal Disease Research Laboratory titres, but only 35.4% had a negative treponemal IgM. Secondary and early latent stage patients had a slower seroreversion of IgM (Hazard Ratio (HR) = 0.73, p = 0.064 and HR = 0.60, p = 0.023, respectively) than those with primary syphilis. A very strong association was observed of time to seroreversion of treponemal IgM with baseline VDRL titre (p < 0.001). Treponemal IgM antibody detection often cannot distinguish between active and successfully treated syphilis. Treponemal IgM may only be useful in the cases recommended in the guidelines, and in cases of untreated syphilis, it could support but not confirm the diagnosis.

Suicidal behaviour in HIV-infected patients in Greece

This study investigated suicide completion and suicide attempts by HIV-infected patients in Greece, which, from the existing literature, are more frequent than those among the general population. The study sample comprised HIV-infected patients who had been monitored for a minimum period of six months from 1992 through 2012 at the "Andreas Sygros" University Hospital in Athens. Among the 1884 patients who were monitored during the study period, 37 suicides were attempted by 28 (1.48%) patients (27 men and 1 woman). Six of them were fatal (0.3%, 52/100,000 person-years) while over the study, 397 patients died. No significant differences concerning main characteristics were recorded among patients with an attempted and those with a completed suicide. Seventeen of the 28 patients (60.71%) demonstrated psychiatric morbidities. Suicide attempts were more numerous before the advent of combined antiretroviral therapy (cART), whereas there was no difference in attempts before and after the Greek financial crisis in 2009. The suicide frequency was higher than that of the general population for the same period. However, it decreased after the introduction of cART. Special attention is required in recording coexisting mental disorders and providing specialized psychiatric care to HIV-infected patients.

Adherence to hepatitis A virus vaccination in HIV-infected men who have sex with men

Although vaccination against hepatitis A virus (HAV) is essential for human immunodeficiency virus (HIV)-infected patients, the uptake of HAV vaccine is reported to be very low. From 2007 to 2012, 912 HIV-infected men in Athens, Greece were screened for exposure to HAV. Two doses of an HAV vaccine were recommended to 569 eligible patients. Reminder cards with scheduled vaccination visits were given to each patient. Among eligible patients, 62.2% (354/569) received both doses. Patients who were fully vaccinated compared with non-adherent patients were natives, older, had undetectable HIV viral load, higher CD4 T cell counts and lower nadir CD4 T cell counts. Multivariate logistic regression revealed that the patient's country of origin (p = 0.024; OR = 2.712; 95% CI, 1.139-6.457), CD4 T cell count (p < 0.001) and nadir CD4 T cell count (p < 0.001) were factors directly associated with adherence. In conclusion, adherence to HAV vaccination was better than in previously published data. Because many of the factors related to vaccination completion are parameters of HIV infection, it appears that physician interest in HIV care and vaccination planning is crucial to enhancing vaccine uptake.
