Analysis of drug-drug interactions in patients with HIV and metabolic syndrome.

BACKGROUND: People with HIV (PWH) are living longer directly related to benefits of highly effective antiretroviral therapy (ART). However, concurrent with improved longevity is the growing prevalence of metabolic comorbidities that drive morbidity and mortality among PWH. There is an increasing repertoire of treatment options for metabolic disorders. Thus, it is important for clinicians to understand the drug-drug interactions (DDIs) between ART and treatments for metabolic disorders. AREAS COVERED: This review will discuss DDIs between contemporary ART and agents used to treat metabolic syndrome (diabetes, dyslipidemia, obesity and hypertension). Literature review of published and unpublished data from manuscripts, conference proceedings, regulatory submissions, and drug prescribing information were conducted from the following sources: PubMed, Google, and Google Scholar through January 2024. EXPERT OPINION: People with HIV have a high prevalence of metabolic disorders. Most significant DDIs between ART and treatments for metabolic disorders are unidirectional with ART as perpetrators, rather than victims, such that careful selection of ART with low DDI propensity can address the concern. However, there are data gaps with DDI data for long-acting ART as well as newer oral and injectable medications for diabetes and weight loss. Nanotechnology-based drug delivery platforms hold promise to address some problematic DDIs.

Rapid cost-effectiveness analysis: hemodialysis versus peritoneal dialysis for patients with acute kidney injury in Rwanda.

BACKGROUND: To ensure the long-term sustainability of its Community-Based Health Insurance scheme, the Government of Rwanda is working on using Health Technology Assessment (HTA) to prioritize its resources for health. The objectives of the study were to rapidly assess (1) the cost-effectiveness and (2) the budget impact of providing PD versus HD for patients with acute kidney injury (AKI) in the tertiary care setting in Rwanda. METHODS: A rapid cost-effectiveness analysis for patients with AKI was conducted to support prioritization. An 'adaptive' HTA approach was undertaken by adjusting the international Decision Support Initiative reference case for time and data constraints. Available local and international data were used to analyze the cost-effectiveness and budget impact of peritoneal dialysis (PD) compared with hemodialysis (HD) in the tertiary hospital setting. RESULTS: The analysis found that HD was slightly more effective and slightly more expensive in the payer perspective for most patients with AKI (aged 15-49). HD appeared to be cost-effective when only comparing these two dialysis strategies with an incremental cost-effectiveness ratio of 378,174 Rwandan francs (RWF) or 367 United States dollars (US$), at a threshold of 0.5 × gross domestic product per capita (RWF 444,074 or US$431). Sensitivity analysis found that reducing the cost of HD kits would make HD even more cost-effective. Uncertainty regarding PD costs remains. Budget impact analysis demonstrated that reducing the cost of the biggest cost driver, HD kits, could produce significantly more savings in five years than switching to PD. Thus, price negotiations could significantly improve the efficiency of HD provision. CONCLUSION: Dialysis is costly and covered by insurance in many countries for the financial protection of patients. This analysis enabled policymakers to make evidence-based decisions to improve the efficiency of dialysis provision.

HIV risk profile and prevention needs of individuals seeking monkeypox (mpox) vaccination in an urban clinic in the U.S.: a brief report.

BACKGROUND: Our study survey assessed HIV risk profile and pre-exposure prophylaxis (PrEP) use among HIV-negative individuals seeking mpox vaccination, elucidating HIV prevention gaps and opportunities. METHODS: Anonymous cross-sectional surveys were self-administered at an urban academic center clinic in New Haven, CT, U.S. (August 18-November 18, 2022). Inclusion criteria included adults presenting for mpox vaccination who consented to the study. The study assessed STI risk (sexual practices, STI history, substance use). For HIV-negative participants, PrEP knowledge, attitudes, and preferences were assessed. RESULTS: Eighty-one of 210 individuals approached completed surveys (survey acceptance and completion rate 38.6%). Majority were cisgender-male (76/81; 93.8%), Caucasian (48/79; 60.8%), with median age 28 years (IQR-15). Nine of 81 (11.5%) self-reported HIV-positivity. Median sexual partner number (6 months prior) was 4 (IQR-5.8). Majority, 89.9% and 75.9%, reported insertive and receptive anal intercourse, respectively. 41% reported lifetime STI history, of whom 12.3% had an STI 6 months prior. Majority (55.8%) used ≥ 1 illicit substance; 87.7% moderate alcohol use. Among HIV-negative respondents, most (95.7%) were aware of PrEP, but only 48.4% used PrEP. CONCLUSION: Individuals seeking mpox vaccination engage in behaviors placing them at increased STI risk and would benefit from PrEP assessment.

Challenges in the Recognition and Management of Acute Kidney Injury by Hospitals in Resource-Limited Settings.

INTRODUCTION: Acute kidney injury (AKI) is prevalent in low- and middle-income countries (LMIC) and is associated with significant morbidity and mortality, particularly among hospitalized patients. Successful strategies for the prevention and management of AKI in these countries are dependent on the capacity of primary care centers to provide optimal initial management of patients at risk for this disorder. METHODS: From December 2018 to February 2019, using mixed methods, we assessed hospital capacity and the knowledge of clinicians relevant to the prevention, diagnosis, and management of AKI in Rwanda. A checklist based on Kidney Disease: Improving Global Outcomes (KDIGO) guidelines and clinical vignette-based assessment tool were used to assess hospital capacity and provider knowledge base, respectively. Data were analyzed using stata 13 with findings reported as simple frequencies or means with standard deviation. Multivariate analysis was used to assess factors associated with a higher knowledge score among clinicians. RESULTS: Ten hospitals and 193 health care providers from sites throughout Rwanda participated in the survey. Surveyed hospitals were equipped with basic general medical equipment but were deficient in diagnostic tools and medical supplies that would allow the diagnosis and nondialytic management of AKI. Although 20% of the hospitals could offer hemodialysis services, peritoneal dialysis services were nonexistent. With regard to knowledge base, the health care providers demonstrated significant deficiencies in the diagnosis and management of AKI. The mean knowledge score for all health providers was 6.3 (±1.5) of a maximum of 11, with a mean (±SD) score for doctors, nurses, and midwives of 6.3 ± 2.05, 6.4 ± 1.3, and 6.08 ± 1.2, respectively. On multivariate analysis, the length of clinical experience and age of the respondents were significantly associated with participants' knowledge score. CONCLUSION: This study documents significant barriers to providing optimal management of AKI in primary health care settings in Rwanda, a resource-limited setting. These include lack of specialized medical personnel, significant knowledge gaps among primary health care providers, suboptimal diagnostic capacity, and limited treatment options for detection and management of AKI.

Perceptions of HIV transmission and pre-exposure prophylaxis among health care workers and community members in Rwanda.

There are too many new HIV infections globally with 1.8 million persons infected in 2016 alone. Pre-exposure prophylaxis (PrEP) holds potential to decrease new infections and is synergistic with efforts currently in place to achieve an end to the AIDS epidemic in Sub-Saharan African, but uptake is limited. Given its novelty, assessing the beliefs and attitudes of healthcare professionals and members of the community towards HIV transmission and PrEP will be helpful to inform implementation efforts. Study was a random survey of 201 community members and 51 healthcare providers, carried out at multiple community sites in Huye district, Southern Province, Rwanda and at Kigali University Teaching Hospital (KUTH). The study findings are that there are still misconceptions about HIV in the community with some respondents believing that HIV is due to punishment from God (5.4%), poverty (3.0%), smoking cigarettes (1.0%), drinking alcohol (2.0%), punishment from ancestors (1.0%) and witchcraft (1.5%), and that its transmission is by mosquito bites (10.9%), sharing food or drinks with a HIV infected person (6.5%) or as a result of carelessness (47.8%). More than 50% of respondents from both groups had insufficient knowledge regarding PrEP, but expressed some interest in PrEP (82.6% of the respondents from the community and 86.5% of the health workers). However, some healthcare workers felt that promotion of safe sex practices (74.5%), HIV testing and treating HIV infected patients (60.8%) would work better than PrEP to decrease new HIV infections. Barriers to PrEP implementation included perceived stigma, delayed access to prevention services at the health facilities while personal-level concerns included lack of family support, reluctance to take a medication daily and fear of being perceived as having HIV. This study showed that health care workers and community members are willing to utilize PrEP in Rwanda, but many challenges exist including limited knowledge about PrEP, stigma, provider and system level service delivery barriers at health facilities among others. More studies are needed to assess ways of addressing and /or eliminating these barriers.

Clinical Profile and Outcome of Patients with Acute Kidney Injury Requiring Hemodialysis: Two Years' Experience at a Tertiary Hospital in Rwanda.

INTRODUCTION: Acute kidney injury (AKI) requiring renal replacement therapy is associated with high mortality. The study assessed the impact of the introduction of hemodialysis (HD) on outcomes of patients with AKI in Rwanda. METHODS: A single center retrospective study that evaluated the clinical profile and survival outcomes of patients with AKI requiring HD [AKI-D] at a tertiary hospital in Rwanda. Data was collected on patients who received HD for AKI from September 2014 to December 2016. Patient demographics, comorbidities, clinical presentation, laboratory tests, and mortality were reviewed and analyzed. Predictors of mortality were assessed using age and gender adjusted multivariate analyses. RESULTS: Of the 82 eligible patients, median age was 38 years (IQR 28-57 years). Males comprised 51% of the cohort. Infectious diseases including malaria, pneumonia, and sepsis (35.1%) and pregnancy-related conditions (26.9%) were the most frequent comorbidities. Pulmonary oedema (54.9%) and uremic encephalopathy (50%) were top indications for HD. Mortality was 34.1%. On multivariate analysis, receipt of <5 sessions of HD (OR = 4.01, 95% CI 1.185-13.61, P = 0.026) and hyperkalemia (OR = 3.23, 95% CI 1.040-10.065, P = 0.043) were associated with mortality. CONCLUSION: The availability of acute hemodialysis in Rwanda has resulted in improved patient survival and persistent hyperkalemia predicted higher mortality.

Blood pressure measurement techniques: Assessing performance in outpatient settings of a tertiary-level hospital in Rwanda.

Cardiovascular diseases (CVD) are the leading cause of mortality globally. Hypertension is a known modifiable risk factor for CVD. Diagnosis and management of hypertension hinges upon accurate blood pressure (BP) measurement. In this study, we assessed performance to recommended guidelines for BP measurement in Rwanda. In 2017, a cross-sectional study investigating performance on 11 techniques recommended for BP measurement was undertaken across outpatient settings of 3 departments at the University Teaching Hospital of Kigali, Rwanda. Performance was checked by an inside observer. The study enrolled 164 patients. The overall mean performance on the 11 BP measurement techniques was 5.69 (±1.02) out of the 11 possible points. There was no significant difference in performance across departments (P = .28). The findings suggest that performance on currently recommended guidelines for BP measurement is not optimal. Going forward, it is important to implement interventions that will enhance performance given that diagnosis and management of hypertension depend upon accurate BP measurement.

Obstructive uropathy as initial presentation of genitourinary tuberculosis and masquerading as a postsurgical complication.

A 46-year-old woman who had a recent total abdominal hysterectomy presented with a 1 month history of lower abdominal pain, 1 week of nausea and vomiting as well as decreased urinary output preceded by a year of significant unintentional weight loss. On renal imaging, she was found to have bilateral hydronephrosis and hydroureters in the setting of bilateral distal ureteric obstruction complicated with acute kidney injury and severe hyperkalaemia requiring haemodialysis. The initial concern was for ureteric injury, a known complication of abdominal hysterectomy procedures, however, a urological intervention, performed 9 months later to relieve the ureteric obstruction, revealed purulent material within the left ureter that was smear positive for acid fast bacilli. A GeneXpert test was positive for Mycobacterium tuberculosis She was diagnosed with genitourinary tuberculosis and responded well to antitubercular treatment and haemodialysis was discontinued after the surgery relieved her ureteric obstruction.
