Religious Leaders as Trusted Messengers in Combatting Hypertension in Rural Tanzanian Communities.

BACKGROUND: Hypertension is a growing public health emergency in rural sub-Saharan Africa. Based on the known influence of religious leaders in rural sub-Saharan Africa and our prior research, we explored perspectives of religious leaders on hypertension and potential strategies to improve hypertension control in their communities. METHODS: We conducted 31 in-depth interviews with Christian (n = 17) and Muslim (n = 14) religious leaders in rural Tanzania. Interviews focused on religious leaders' perceptions of hypertension and how they could play a role in promoting blood pressure reduction. We used interpretative phenomenological analysis, a qualitative research method, to understand religious leaders' perspectives on, and experiences with, hypertension. RESULTS: Three main themes emerged during analysis. First, we found that perceptions about causes, treatment, and complications of hypertension are influenced by religious beliefs. Second, religious beliefs can enable engagement with hypertension care through religious texts that support the use of biomedical care. Third, religious leaders are enthusiastic potential partners for promoting hypertension control in their communities. These themes were consistent between religion and gender of the religious leaders. CONCLUSIONS: Religious leaders are eager to learn about hypertension, to share this knowledge with others and to contribute to improved health in their communities.

Development and evaluation of a pilot nurse case management model to address multidrug-resistant tuberculosis (MDR-TB) and HIV in South Africa.

SETTING: Multidrug-resistant tuberculosis (MDR-TB) unit in KwaZulu-Natal, South Africa. OBJECTIVE: To develop and evaluate a nurse case management model and intervention using the tenets of the Chronic Care Model to manage treatment for MDR-TB patients with a high prevalence of human immunodeficiency virus (HIV) co-infection. DESIGN: A quasi-experimental pilot programme utilizing a nurse case manager to manage care for 40 hospitalized MDR-TB patients, 70% HIV co-infected, during the intensive phase of MDR-TB treatment. Patients were followed for six months to compare proximal outcomes identified in the model between the pre- and post-intervention period. RESULTS: The greatest percent differences between baseline and six-month MDR-TB proximal outcomes were seen in the following three areas: baseline symptom evaluation on treatment initiation (95% improvement), baseline and monthly laboratory evaluations completed per guidelines (75% improvement), and adverse drug reactions acted upon by medical and/or nursing intervention (75% improvement). CONCLUSION: Improvements were identified in guideline-based treatment and monitoring of adverse drug reactions following implementation of the nurse case management intervention. Further study is required to determine if the intervention introduced in this model will ultimately result in improvements in final MDR-TB treatment outcomes.

Prevalence and seroincidence of hepatitis B and hepatitis C infection in high risk people who inject drugs in china and Thailand.

We determined the prevalence and incidence of HBV and HCV infection in people who inject drugs (PWIDs) at high risk for HIV in China and Thailand and determined the association of HBV and HCV incidence with urine opiate test results and with short-term versus long-term buprenorphine-naloxone (B-N) treatment use in a randomized clinical trial (HPTN 058). 13.8% of 1049 PWIDs in China and 13.9% of 201 PWIDs in Thailand were HBsAg positive at baseline. Among HBsAg negative participants, the HBsAg incidence rate was 2.7/100 person years in China and 0/100 person years in Thailand. 81.9% of 1049 PWIDs in China and 59.7% of 201 in Thailand were HCV antibody positive at baseline. The HCV confirmed seroincidence rate among HCV antibody negative PWIDs was 22/100 person years in China and 4.6/100 person years in Thailand. Incident HBsAg was not significantly different in the short-term versus long-term B-N arm in China or Thailand. Participants with positive opiate results in at least 75% of their urines during the time period were at increased risk of incident HBsAg (HR = 5.22; 95% CI, 1.08 to 25.22; P = 0.04) in China, but not incident HCV conversion in China or Thailand.

Physician estimate of antiretroviral adherence in India: poor correlation with patient self-report and viral load.

Adherence to antiretroviral therapy (ART) is critical in maintaining viral suppression and minimizing resistance in HIV-infected patients. We compared physician estimates of their patients' ART adherence with participant's self-reported adherence to determine patient-provider agreement and identify correlates of discordance in three private clinics in Mumbai, India. Between December 2004 and April 2005, 277 persons receiving ART at three private clinics in Mumbai, India, were interviewed regarding adherence to ART using the Adult AIDS Clinical Trials Group questionnaire. Physicians were also asked to assess their patients' adherence. Quantitative HIV-1 RNA level was determined for 200 participants. Agreement between provider estimate of adherence and participant self-report was low, kappa = 0.058 (95% confidence interval [CI] 0.011-0126). Of 200 participants whose viral load was obtained, viral suppression was associated with participant self-reported adherence (odds ratio [OR] 3.08; 95% CI 1.65-5.74; p < 0.05), but not with provider estimated adherence (OR 1.2; 95% CI 0.67-2.14; p = 0.54). Cost of ART was positively associated with physician underestimation of participant adherence and older age was negatively associated. No independent correlates of physician overestimation of participant adherence were found. There was poor agreement between physician estimate of adherence and patient self-report. Providers should avoid using their own assessment of patient ART adherence. Instead, providers should rely on effective and validated measures, especially when viral load or drug level monitoring are not readily available.

One-, two-, and three-class resistance among HIV-infected patients on antiretroviral therapy in private care clinics: Mumbai, India.

HIV-infected patients receiving antiretroviral (ARV) therapy (ART) in India are not all adequately virally suppressed. We analyzed ARV drug resistance in adults receiving ART in three private clinics in Mumbai, India. HIV viral load was measured in 200 patients with the Roche AMPLICOR HIV-1 Monitor Test, v1.5. HIV genotyping was performed with the ViroSeq HIV-1 Genotyping System for 61 participants who had HIV-1 RNA >1000 copies/ml. Genotyping results were obtained for 51 samples. The participants with resistance results were on ART for a median of 24 months and were on their current regimen for a median of 12 months (median CD4 cell count: 217 cells/mm(3); median HIV viral load: 28,200 copies/ml). ARV regimens included nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimens (n = 27), dual nucleoside reverse transcriptase inhibitors (NRTIs, n = 19), protease inhibitor (PI)-based regimens (n = 3), and other regimens (n = 2). Twenty-six participants (51.0%) were on their first ARV regimen and 24 (47%) reported >95% adherence. Forty-nine participants (96.1%) had resistance to at least one ARV drug; 47 (92.2%) had NRTI resistance, 32 (62.7%) had NNRTI resistance, and four (7.8%) had PI resistance. Thirty (58.8%) had two-class resistance and three (5.9%) had three-class resistance. Four (8%) had three or more resistance mutations associated with etravirine resistance and two (4%) had two mutations associated with reduced darunavir susceptibility. Almost all patients with HIV-1 RNA >1000 copies/ml had NRTI resistance and nearly two-thirds had NNRTI resistance; PI resistance was uncommon. Nearly 60% and 6% had two- and three-class resistance, respectively. This emphasizes the need for greater viral load and resistance monitoring, use of optimal ART combinations, and increased availability of second- and third-line agents for patients with ARV resistance.

Adherence to antiretroviral therapy and virologic suppression among HIV-infected persons receiving care in private clinics in Mumbai, India.

BACKGROUND: Adherence to antiretroviral therapy (ART) and correlates of adherence and virologic suppression among human immunodeficiency virus (HIV)-infected persons receiving ART in private, outpatient clinics in India is unknown. METHODS: Between December 2004 and April 2005, persons receiving ART at 3 private clinics in Mumbai, India, were interviewed regarding HIV care and adherence to ART. Physicians also completed a survey for each participant. Quantitative HIV-1 RNA level was determined for 200 participants. RESULTS: Of 279 participants, 73% reported > or = 95% adherence to ART. Adherence was positively associated with age > or = 50 years (adjusted odds ratio [aOR], 3.90), presence of comorbid conditions (aOR, 1.92), medication self-efficacy (aOR, 4.01), absence of pain in the past month (aOR, 2.14), and support from family and friends (aOR, 2.57). Lack of reminders from family members to take medication (aOR, 0.27) was negatively associated with adherence. Of 200 participants, 127 (63.5%) had virologic suppression (RNA level, < 400 copies/mL). Independent correlates of suppression were a regimen containing > or = 3 ART drugs (aOR, 5.52), first ART regimen (aOR, 3.28), adherence to therapy > or = 95% (aOR, 5.70), female sex (aOR, 3.19), and a physical component score > or = 50 (aOR, 1.07). CONCLUSION: Self-reported adherence to ART in a sample of patients attending Mumbai's private clinics was relatively high. However, the fact that a detectable viral level was found in nearly 40% of patients suggests that second-line ART regimens, as well as an emphasis on adherence and appropriate ART regimens in India, is needed.

Same-sex behavior and high rates of HIV among men attending sexually transmitted infection clinics in Pune, India (1993-2002).

OBJECTIVES: To determine HIV/sexually transmitted infection (STI) prevalence, trends, and risk behaviors of men who have sex with men (MSM) and compare these with those of non-MSM attending STI clinics in Pune, India over a 10-year period. DESIGN: Cross-sectional. METHODS: From 1993 through 2002, men attending 3 STI clinics in Pune underwent HIV/STI screening. Demographic, risk behavior, clinical, and laboratory data were collected using standardized questionnaires and laboratory procedures. RESULTS: Of 10,785 men screened, 708 (6.6%) were MSM. Among these 708 MSM, 189 (31.7%) had 10 or more lifetime partners, 253 (35.7%) were married, 163 (23.1%) had sex with a hijra (eunuch), and 87 (13.3%) had exchanged money for sex. A total of 134 (18.9%) were HIV-positive, 149 (21.5%) had genital ulcer disease (GUD), 37 (5.8%) had syphilis, and 29 (4.3%) had gonorrhea (GC). Over the decade, neither HIV nor GC prevalence changed among MSM (P = 0.7), but syphilis and GUD decreased significantly (P < 0.0001). Compared with non-MSM, MSM were more likely to initiate sexual activity at age <16 years, to have >10 lifetime partners, to have sex with a hijra, and to use condoms regularly, but they did not differ significantly in HIV prevalence and had a lower prevalence of GC, GUD, and syphilis. Independent factors associated with HIV among MSM were employment (adjusted odds ratio [AOR] = 3.08; P = 0.02), history of GUD (AOR = 1.86; P = 0.003), and syphilis (AOR = 2.09; P = 0.05). CONCLUSIONS: Same-sex and high-risk sexual behaviors are prevalent among men attending STI clinics in India. Although syphilis and GUD rates decreased, HIV prevalence remained high during the decade, highlighting the importance of additional targeted efforts to reduce HIV risk among all men, including MSM, in India.

Complication rates among cancer patients with peripherally inserted central catheters.

PURPOSE: Peripherally inserted central catheters (PICCs) are frequently used to deliver outpatient courses of intravenous therapy. However, the rates and risks of complication for this device have not been well-studied. Our objective was to determine the incidence and risk factors of PICC-related complications with a 1-year prospective observational study. PATIENTS AND METHODS: All PICCs inserted in adult and pediatric patients at Memorial Sloan-Kettering Cancer Center (MSKCC) were followed prospectively. The device insertion team, inpatient nurses, and various home-care companies and outside institutions collected longitudinal data. RESULTS: Three hundred fifty-one PICCs were inserted during the study period and followed for a total of 10,562 catheter-days (median placement, 15 days; range, 1 to 487 days). Two hundred five PICCs (58%) were managed by home-care companies and outside institutions, and 146 PICCs (42%) were managed exclusively at MSKCC. For these 205 PICCs, 131 nurses from 74 home-care companies and institutions were contacted for follow-up clinical information. In all, 115 (32.8%) of 351 PICCs were removed as a result of a complication, for a rate of 10.9 per 1,000 catheter-days. Patients with hematologic malignancy or bone marrow transplant were more likely to develop a complication, whereas those with metastatic disease were less likely. CONCLUSION: Complications occur frequently among cancer patients with PICCs, and long-term follow-up is onerous. Despite a high complication rate, the ease of insertion and removal argues for continued PICC use in the cancer population.
