Lymphogranuloma venereum (LGV) is a sexually transmitted disease (STD) caused by serovars L1-L3 of Chlamydia trachomatis. Rare in the western world prior to 2003, different outbreaks or clusters of LGV have been reported in Europe, North America and Australia among men who have sex with men (MSM) over the past few years. The majority were HIV infected MSM with high-risk sexual behaviour and a high rate of concomitant STD, including hepatitis C. Most of them presented with a proctitis syndrome and only a few with the classical bubonic form. A previously non-described serovar, L2b, has been identified as the main causative agent of the epidemic. A delay in diagnosis has been the rule because of the misleading symptomatology of LGV proctitis, the unfamiliarity of the disease to physicians, and the lack of a routine diagnostic test for LGV serovars. It is crucial to increase the awareness of the disease among physicians for prompt diagnosis and treatment, to avoid complications, and to stop ongoing transmission. It has additional public health implications since LGV may facilitate the transmission and acquisition of HIV and other STD.
With more effective and widespread antiretroviral treatment, the overall incidence of AIDS- or HIV-related death has decreased dramatically. Consequently, as patients are aging, cardiovascular disease (CVD) has emerged as an important cause of morbidity and mortality in the HIV population. The incidence of CVD overall in HIV is relatively low, but it is approximately 1.5-2-fold higher than that seen in age-matched HIV-uninfected individuals. Multiple factors are believed to explain this excess in risk such as overrepresentation of traditional cardiovascular risk factors (particularly smoking), toxicities associated with cumulative exposure to some antiretroviral agents, together with persistent chronic inflammation, and immune activation associated with HIV infection. Tools are available to calculate an individual's predicted risk of CVD and should be incorporated in the regular follow-up of HIV-infected patients. Targeted interventions to reduce this risk must be recommended, including life-style changes and medical interventions that might include changes in antiretroviral therapy.
With widespread and effective antiretroviral therapy, the life expectancy in the HIV population has dramatically improved over the last two decades. Consequently, as patients are aging with HIV, other age-related comorbidities, such as metabolic disturbances and cardiovascular disease (CVD), have emerged as important causes of morbidity and mortality. An overrepresentation of traditional cardiovascular risk factors (RF), toxicities associated with long exposure to antiretroviral therapy, together with residual chronic inflammation and immune activation associated with HIV infection are thought to predispose to these metabolic complications and to the excess risk of CVD observed in the HIV population.
The metabolic syndrome (MS) represents a clustering of RF for CVD that includes abdominal obesity, hypertension, dyslipidemia, and insulin resistance.
Hypertension is a prevalent feature of the MS in HIV, in particular in the aging population, and constitutes an important RF for CVD.
Physicians should screen their patients for metabolic and cardiovascular risk at the regular visits to reduce MS and the associated CVD risk among people aging with HIV, since many of RF are under-diagnosed and under-treated conditions.
Interventions to reduce these RF can include life-style changes and pharmacological interventions such as antihypertensive and lipid-lowering therapy, and treatment of glucose metabolism disturbances. Changes in antiretroviral therapy to more metabolic neutral antiretroviral drugs may also be considered.
European infectious diseases physicians, microbiologists and pathologists must be aware of histoplasmosis, particularly when facing HIV-infected immigrants from endemic areas. This is increasingly important due to migration and travel activities from these areas.
Pre-exposure prophylaxis (PrEP) is a new preventive treatment for individuals at high-risk for HIV infection, such as men who has sex with men (MSM). Studies have confirmed the efficacy but concerns about the potential induction of risk compensation remains. We aimed to assess the incidence of sexually transmitted infections (STIs) after PrEP initiation as a proxy for sexual risk behavior. This case-crossover study used data from medical records and from the Danish Microbiology Database from patients who initiated PrEP at the Region of Southern Denmark between 2017 and 2019. Poisson regression was used to assess STI incidence 6 months after PrEP initiation versus the 6 months before. To identify potential risk factors, we compared individuals with an increased STI incidence after PrEP initiation with those without, using logistic regression. In total, 46 MSM initiated PrEP in the study period. We found a significant increase in the number of positive samples for STI after PrEP initiation (IRR 1.83; 95% CI [1.03, 3.26]) and a tendency for higher incidence of STI episodes (1.67; 95% CI [0.91, 3.13]). The increase was concentrated to a group of users, but no significant correlation was found between increasing incidence and the baseline factors examined. We observed a degree of risk compensation after the implementation of PrEP among MSM, clustering to a group of users. Our results highlight the importance of frequent STI screening among MSM on PrEP as timely diagnosis could contribute to an overall decrease in STI incidence and incidence among MSM.
ObjectivesWe aimed to determine the fraction of HIV-diagnosed individuals who had primary health care (PHC) contacts 3 years prior to HIV diagnosis and whether the risk of HIV diagnosis and degree of immunodeficiency were associated with the frequency of visits or procedures performed.
MethodsWe used data from national registries to conduct a population-based nested case-control study. Cases were individuals diagnosed with HIV infection in Denmark from 1998 to 2016. Population controls were extracted from the general population matched 13:1 on gender and age. We used conditional logistic regression. As there was a statistically significant interaction, analyses were further stratified by gender and Danish/non-Danish origin.
ResultsWe identified 2784 cases and 36 192 controls. Ninety-three per cent of cases and 88% of controls attended PHC at least once in the 3 years prior to diagnosis, with a higher median number of visits to PHC (NVPC) for cases. We found a statistically significant positive association between NVPC and risk of subsequent HIV diagnosis in men and non-Danish women. A U-shaped association between NVPC and risk of HIV diagnosis among Danish women. No substantial association between NVPC and degree of immunodeficiency was found. Risk of HIV diagnosis and degree of immunodeficiency were weakly associated with type of procedures performed.
ConclusionsFor most HIV-infected individuals, there seem to be many opportunities for earlier diagnosis in PHC. In men and non-Danish women, the risk of HIV diagnosis but not the degree of immunodeficiency was related to NVPC. The results suggest that the type of medical procedure performed cannot not be used as a guide by the primary physician to indicate which patients to test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
