RESUMO

The HIV public health messages in South Africa have increased. Our objective was to evaluate changes over time in HIV testing behaviour, prevalence and knowledge. We prospectively enrolled adults (≥18 years) prior to HIV testing at one urban and one peri-urban outpatient department in Durban, South Africa. A baseline questionnaire administered before testing included the number of prior HIV tests and four knowledge items. We used test results to estimate previously undiagnosed HIV prevalence among those tested. We assessed linear trends over enrollment. From November 2006 to August 2010, 5229 subjects enrolled and 4877 (93%) were HIV tested and had results available. Subjects reporting prior testing over time increased, from 13% in study year 1 to 42% in year 4 (linear trend p < 0.001). The HIV prevalence among those tested declined steadily and significantly over time, from 64% of enrollees in study year 1 to 39% in the final year (linear trend p < 0.001). The percentage of subjects who recognised that medicine can help people with HIV live longer increased from 80% in study year 1 to 96% in study year 4. Rates of HIV testing have increased and prevalence among those tested has decreased in outpatients in Durban, South Africa.

RESUMO

Progressive multifocal leukoencephalopathy is a rare, demyelinating disease of the central nervous system caused by JC virus. Fewer than 30 cases have been reported in HIV- and non-infected children. We report the case of a 15-year-old girl with progressive multifocal leukoencephalopathy and AIDS who presented with nystagmus, dysarthria and ataxia. Following combined antiretroviral therapy, she developed immune reconstitution inflammatory syndrome, which proved fatal.

RESUMO

OBJECTIVES: Although youth (12-24 years) in Sub-Saharan Africa have a high HIV risk, many have poor access to HIV testing services and are unaware of their status. Our objective was to evaluate the proportion of adolescents (12-17 years) and young adults (18-24 years) who underwent HIV testing and the prevalence among those tested in an urban adult outpatient clinic with a routine HIV testing program in Durban, South Africa. DESIGN: We conducted a retrospective cross-sectional analysis of adolescent and young adult outpatient records between February 2008 and December 2009. METHODS: We determined the number of unique outpatient visitors, HIV tests, and positive rapid tests among those tested. RESULTS: During the study period, 956 adolescents registered in the outpatient clinic, of which 527 (55%) were female. Among adolescents, 260/527 (49%, 95% CI 45-54%) females underwent HIV testing compared to 129/429 (30%, 95% CI 26-35%) males (p<0.01). The HIV prevalence among the 389 (41%, 95% CI 38-44%) adolescents who underwent testing was 16% (95% CI 13-20%) and did not vary by gender (p = 0.99). During this period, there were 2,351 young adult registrations, and of these 1,492 (63%) were female. The proportion consenting for HIV testing was similar among females 980/1,492 (66%, 95% CI 63-68%) and males 543/859 (63%, 95% CI 60-66%, p = 0.25). Among the 1,523 (65%, 95% CI 63-67%) young adults who underwent testing, the HIV prevalence was 22% (95% CI 19-24%) in females versus 14% in males (95% CI 11-17%, p<0.01). CONCLUSIONS: Although the HIV prevalence is high among youth participating in an adult outpatient clinic routine HIV program, the uptake of testing is low, especially among 12-17 year old males. There is an urgent need to offer targeted, age-appropriate routine HIV testing to youth presenting to outpatient clinics in epidemic settings.

RESUMO

We evaluated the prevalence and correlates of depressive symptoms prior to HIV diagnosis and determined the effect of these symptoms on seeking HIV care at an urban and rural clinic in Durban, South Africa. Adults were administered a questionnaire which included the 5-item Mental Health Index (MHI-5) before HIV testing. We determined the depressive symptoms among HIV-infected subjects. Of 1,545 newly-diagnosed HIV-infected subjects, 55% had depressive symptoms by MHI-5 score. Enrolling at the urban clinic and decreasing functional activity score were associated with depressive symptoms. Subjects with depressive symptoms who were referred for HIV testing by a healthcare provider were less likely to obtain a CD4 count than those without depressive symptoms who self-referred for testing. Depressive symptoms were common among newly-diagnosed HIV-infected participants and impacted CD4 uptake. Depression screening at the time of HIV diagnosis is critical for improving linkage to mental health and HIV services in South Africa.

RESUMO

Balantidium coli is a cosmopolitan parasitic-opportunistic pathogen that can be found throughout the world. Pigs are its reservoir hosts, and humans become infected through direct or indirect contact with pigs. In rural areas and in some developing countries where pig and human fecal matter contaminates the water supply, there is a greater likelihood that balantidiosis may develop in humans. The infection may be subclinical in humans, as it mostly is in pigs, or may develop as a fulminant infection with bloody and mucus-containing diarrhea; this can lead to perforation of the colon. The disease responds to treatment with tetracycline or metronidazole. Balantidiosis is a disease that need never exist given access to clean water and a public health infrastructure that monitors the water supply and tracks infections. Its spread can be limited by sanitary measures and personal hygiene, but it is a disease that will be around as long as there are pigs. Immunocompromised individuals have developed balantidiosis without any direct contact with pigs, perhaps with rats or contaminated produce as a possible source of infection. For the clinician, balanatidiosis should be included in the differential diagnosis for persistent diarrhea in travelers to or from Southeast Asia, the Western Pacific islands, rural South America, or communities where close contact with domestic swine occurs. Warming of the earth's surface may provide a more favorable environment, even in the now-temperate areas of the world, for survival of trophic and cystic stages of Balantidium, and its prevalence may increase. Effective sanitation and uncontaminated water are the most useful weapons against infection. Fortunately, balantidiosis responds to antimicrobial therapy, and there have been no reports of resistance to the drugs of choice.
