The Acceptability and Perceived Usefulness of a Weekly Clinical SMS Program to Promote HIV Antiretroviral Medication Adherence in KwaZulu-Natal,South Africa

Short message service (SMS) text messages have been used to remind and encourage patients to take ART in research studies. However, few studies have assessed the feasibility and acceptability of SMS in routine clinical practice. We report patient perspectives on a weekly SMS adherence support program after implementation into clinical care at an HIV clinic in KwaZulu-Natal, South Africa. We conducted structured interviews with a cross-sectional convenience sample of 100 adult patients who were invited to join the program, 88 of whom had received a program SMS. Of these respondents, 81 (92 %) would recommend the program to a friend. Sixty-eight (77 %) felt the program helped them remember clinic appointments, a response associated with male gender [odds ratio (OR) 5.88, 95 % confidence interval (CI) 1.52–23.26, P = 0.011] and HIV disclosure outside the home [OR 3.40, 95 %CI 1.00–11.60, P = 0.050]. This clinical SMS adherence program was found to have high patient-perceived usefulness.     

Perceptions About Local ART Adherence Norms and Personal Adherence Behavior Among Adults Living with HIV in Rural Uganda

AIDS and Behavior - Although misperceived norms often drive personal health behaviors, we do not know about this phenomenon in the context of antiretroviral therapy (ART) adherence. We conducted a...     

Real-time PCR assay for detection of quinolone-resistant Neisseria gonorrhoeae in urine samples

A need exists for the development of applicable surveillance tools to detect fluoroquinolone-resistant Neisseria gonorrhoeae (QRNG) in urine samples. We describe here a real-time PCR assay for detecting mutations in the Ser91 codon of the gyrA gene of N. gonorrhoeae in urine specimens. We tested 96 urine samples collected along with Gonorrhea Isolate Surveillance Project (GISP) urethral swab samples and compared the results with matched MICs of ciprofloxacin, as reported by the regional GISP laboratory. We then tested 100 urine specimens, known to be gonorrhea positive by nucleic acid amplification testing, provided by females to challenge the real-time PCR assay with urine specimens containing potentially less target DNA content than specimens from symptomatic males. With an MIC threshold of 0.125 mug of ciprofloxacin/ml, our assay correctly identified resistance in 41 of 44 (93.2%; 95% confidence interval [CI] = 81.3 to 98.6%) corresponding resistant culture specimens and correctly identified 51 of 51 (100%; 95% CI = 93.0 to 100%) susceptible specimens. One specimen did not amplify. The assay successfully amplified the gyrA amplicon and determined a susceptibility genotype in 72 of 100 (72%) urine specimens collected from female patients. We developed an assay for detecting QRNG in urine specimens that correlated well with MIC results of cultured specimens and had moderate sensitivity with urine specimens. This methodology might fulfill the need for a QRNG detection system for urine specimens, a useful characteristic in the age of nucleic acid amplification testing for gonococcal infection.     

Urgent need to improve programmatic management of patients with HIV failing first-line antiretroviral therapy

Introduction:Delayed identification and response to virologic failure in case of first-line antiretroviral therapy (ART) in resource-limited settings is a threat to the health of HIV-infected patients. There is a need for the implementation of an effective, standardized response pathway in the public sector.Discussion:We evaluated published cohorts describing virologic failure on first-line ART. We focused on gaps in the detection and management of treatment failure, and posited ways to close these gaps, keeping in mind scalability and standardization. Specific shortcomings repeatedly recorded included early loss to follow-up (>20%) after recognized first-line ART virologic failure; frequent delays in confirmatory viral load testing; and excessive time between the confirmation of first-line ART failure and initiation of second-line ART, which exceeded 1 year in some cases. Strategies emphasizing patient tracing, resistance testing, drug concentration monitoring, adherence interventions, and streamlined response pathways for those failing therapy are further discussed.Conclusion:Comprehensive, evidence-based, clinical operational plans must be devised based on findings from existing research and further tested through implementation science research. Until this standard of evidence is available and implemented, high rates of losses from delays in appropriate switch to second-line ART will remain unacceptably common and a threat to the success of global HIV treatment programs.     

High-output left ventricular failure after dextran use in an operative hysteroscopy.

High-output left ventricular failure occurred in a patient after a difficult case of hysteroscopic lysis of adhesions using dextran as a distension medium. The excessive dissection in the uterine wall, the long duration of the operation, and the large volumes of dextran probably caused intravasation of dextran into the systemic circulation inducing a significant shift of fluids from the third space. This was possibly assisted by the large volume of fluids given intravenously in a 45-kg patient initiating the reported sequence of events.     

Performance of rapid syphilis tests in venous and fingerstick whole blood specimens

OBJECTIVE: Rapid syphilis screening could facilitate case-identification during U.S. outbreaks. GOAL: The goal of this study was to determine the performance of 3 rapid syphilis tests in whole blood specimens in the laboratory and in patients at a sexually transmitted disease (STD) clinic. STUDY: We tested whole blood samples from STD clinic patients with 3 rapid tests and compared results with the serum treponemal pallidum particle agglutination (TP-PA) test. We evaluated the best performing of the 3 rapid tests on fingerstick specimens from STD clinic patients. RESULTS: The Abbott Determine TP (n = 127) had the highest sensitivity (88%; 95% confidence interval [CI], 81-96%) and lowest rate of indeterminate tests (0.8%), followed by Guardian Biosciences One Step (n = 116) (sensitivity 72%; 95% CI, 60-84%; indeterminate 6.5%), and Phoenix Biotech Trep-Strip IV (n = 71) (sensitivity 70%; 95% CI, 54-85%; indeterminate 30.3%). All 3 tests were 100% specific. The Abbott Determine TP showed excellent performance on fingerstick specimens (n = 99), exhibiting 100% sensitivity (95% CI, 93-100%), 100% specificity, and 2.9% indeterminate. CONCLUSIONS: The Abbott Determine TP test was an easy and accurate test that could facilitate rapid detection of syphilis in at-risk patients.     

Sexual Relationship Power and Malnutrition Among HIV-Positive Women in Rural Uganda

Inequality within partner relationships is associated with HIV acquisition and gender violence, but little is known about more pervasive effects on women's health. We performed a cross-sectional analysis of associations between sexual relationship power and nutritional status among women in Uganda. Participants completed questionnaires and anthropometric measurements. We assessed sexual relationship power using the Sexual Relationship Power Scale (SRPS). We performed logistic regression to test for associations between sexual relationship power and poor nutritional status including body mass index, body fat percentage, and mid-upper arm circumference. Women with higher sexual relationship power scores had decreased odds of low body mass index (OR 0.29, p = 0.01), low body fat percentage (OR 0.54, p = 0.04), and low mid-upper arm circumference (OR 0.22, p = 0.01). These relationships persisted in multivariable models adjusted for potential confounders. Targeted interventions to improve intimate partner relationship equality should be explored to improve health status among women living with HIV in rural Africa.
