Low tuberculosis knowledge among HIV-infected patients in a high HIV prevalence region within southeast India.

SETTING: A private multispecialty hospital in Kakinada, Andhra Pradesh, India. METHODS: A survey of knowledge, attitudes, and perceptions adapted from a pretested questionnaire was administered to 128 HIV-infected adults, from July to August 2008. RESULTS: A total of 31% had not heard of tuberculosis (TB), with 15 (38%) currently receiving anti-TB therapy or had received it in the past. Of those familiar with TB, 70% could not list a method by which it was spread. Low education attainment, female sex, and less frequent television exposure were associated with low TB literacy. CONCLUSIONS: HIV-infected patients in southeast India have poor knowledge of TB and the methods by which it is spread. Scale-up of patient-directed educational programs is necessary to help control TB in India.

Will patients "opt in" to perform their own rapid HIV test in the emergency department?

OBJECTIVE: We evaluate the feasibility and accuracy of existing point-of-care HIV tests performed by an untrained patient compared with the routinely used HIV point-of-care test offered to patients in 2 urban emergency departments (EDs). METHODS: From April 2008 through December 2009, patients who had completed a standard HIV oral fluid test performed by a trained health care professional and who were unaware of their results were recruited to perform a rapid point-of-care HIV test. Patients were given a choice of the oral fluid or the fingerstick blood point-of-care test. Evaluation of acceptability to perform the mechanics of the test was accessed by questionnaire. For the "self-test," the participant obtained his or her own sample and performed the test. The patient's results were compared with standard oral fluid results obtained by the health care professional. RESULTS: Overall, 478 of 564 (85%) patients receiving a standard oral fluid HIV test volunteered, with a mean age of 38 to 39 years. Ninety-one percent of participants chose oral fluid and 9% chose blood (P<.05). Self-test results were 99.6% concordant with health care professionals' test results. For the self-testers, 94% of oral fluid testers and 84.4% of blood testers reported trusting the self-administered test result "very much." Furthermore, 95.6% of the oral fluid group and 93.3% of the blood group would "probably" or "definitely" perform a test at home, if available. CONCLUSION: This study demonstrated that a significant proportion of patients offered a self-HIV point-of-care test volunteered and preferred using oral fluid. Patients' results agreed with standard HIV point-of-care results. The majority of participants trusted their results and would perform a point-of-care HIV test at home, given the opportunity.

Utilising the internet to test for sexually transmitted infections: results of a survey and accuracy testing.

BACKGROUND: Searching the internet for information about sexually transmitted infections (STI) is common. The goal of the study was to discover which internet sites offer STI tests and obtain information about the services and their validity. METHODS: Using internet web-based search engines, information was collected from the sites about STI testing services, costs and types of tests offered, and tests were evaluated for accuracy. 'Business' functions regarding consent and return of results were investigated. Contact attempts were made by phone, e-mail or 'contact us' links and by mail. Test kits were ordered from six commercial internet sites and one public health site. Their accuracy was evaluated for chlamydia and gonorrhoea. RESULTS: The study identified 27 national/international internet sites offering STI self-collection kits and services. Tests were available for gonorrhoea, syphilis, chlamydia, HIV, herpes, hepatitis viruses, trichomonas, mycoplasma and 'gardnerella'. All attempts to administer the survey yielded unsatisfactory results. After sending the survey by mail/e-mail to all the sites, four responded, two with the survey. Six websites appeared invalid based on non-deliverable e-mails and returned letters. The remainder did not respond. Test results were obtained from five of seven ordered kits. Two websites who were sent mocked urine specimens never provided results. The two 'perform-it-yourself' kits yielded false-negative results. Two mail-in urine specimens yielded correct positive results. The public health site kit yielded correct positive results. CONCLUSIONS: The internet STI testing sites were difficult to contact and demonstrated unwillingness to answer consumer-specific questions. Test accuracy varied, with home tests having poor accuracy and mail-in specimens demonstrating high accuracy.

Performance of three nucleic acid amplification tests for detection of Chlamydia trachomatis and Neisseria gonorrhoeae by use of self-collected vaginal swabs obtained via an Internet-based screening program.

Use of self-obtained vaginal specimens processed by nucleic acid amplification tests (NAATs) has significantly increased the utilization of nontraditional locations for Chlamydia trachomatis and Neisseria gonorrhoeae screening programs. One important emerging source of such venues includes home-based self-sampling kits available via the Internet. The objective of our study was to evaluate the performance of three commercially available NAATs (Becton-Dickinson ProbeTec SDA, Gen-Probe Aptima Combo2 TMA, and Roche Amplicor PCR) for detection of C. trachomatis and N. gonorrhoeae in vaginal samples obtained via an Internet-based screening program. From July 2004 to August 2005, 500 self-collected vaginal swabs were tested for C. trachomatis and N. gonorrhoeae by using all three NAATs. Another 500 samples were collected between August 2005 and November 2007 and tested by ProbeTec and Combo2; PCR testing was discontinued due to low specificity for N. gonorrhoeae. All tests were conducted according to the manufacturers' procedures; the "gold standard" for an infected C. trachomatis or N. gonorrhoeae patient was defined as > or = 2 positive NAAT results. Of the first 500 swabs submitted, 46 were C. trachomatis infected (9.2%) and 5 were N. gonorrhoeae infected (1.0%), and 3 of these were coinfected (0.6%). All C. trachomatis and N. gonorrhoeae Combo2-positive/ProbeTec-negative samples were confirmed as true positives by an alternative NAAT. For C. trachomatis, ProbeTec, Combo2, and PCR had sensitivities of 82.6%, 100%, and 100%, with specificities of 100%, 100%, and 99.3%, respectively. For N. gonorrhoeae, ProbeTec, Combo2, and PCR had sensitivities of 80%, 100%, and 100%, with specificities of 100%, 100%, and 98.8%, respectively. Of the total 1,000 swabs submitted, 92 were C. trachomatis infected (9.2%) and 15 were N. gonorrhoeae infected (1.5%), and 7 of these were coinfected (0.7%). There were no ProbeTec-positive/Combo2-negative samples. For C. trachomatis, ProbeTec and Combo2 had sensitivities of 81.5% and 100%, with specificities of 100% and 100%, respectively. For N. gonorrhoeae, ProbeTec and Combo2 had sensitivities of 80% and 100%, with specificities of 100% and 100%, respectively. Overall, ProbeTec had 17 C. trachomatis false-negative results (1.7%) and 3 N. gonorrhoeae false-negative results (0.3%), while Combo2 had none. Our results were consistent with the sensitivities and specificities stated by the manufacturers. NAATs perform well for detection of chlamydia and gonorrhea with self-obtained vaginal swabs shipped in a dry state to a laboratory. For 1,000 self-collected vaginal swabs tested by NAATs, the sensitivities for C. trachomatis and N. gonorrhoeae for Combo2 were 100% and 100%, while they were 81.5% and 80%, respectively, for ProbeTec. For 500 PCR samples, the C. trachomatis sensitivity was 100% and the N. gonorrhoeae sensitivity was 100%, with specificities of 99.3% and 98.8%, respectively.
