Statin gap in patients living with HIV: assessing dose appropriateness

High low-density lipoprotein cholesterol levels in people with HIV by individual cardiovascular risk: A retrospective observational study

BACKGROUND

People with HIV (PWH) are at increased risk of atherosclerotic cardiovascular disease (ASCVD). Lowering low-density lipoprotein cholesterol (LDL-C) is central of cardiovascular disease prevention. The aim of this study was to assess the prevalence, treatment, and control of high LDL-C levels as assessed on the basis of the ASCVD risk profiles indicated by European Society of Cardiology (ESC) guidelines of a cohort of PWH in order to evaluate the state of LDL-C management in current clinical practice.

METHODS

We retrospectively assessed the prevalence, treatment, and control of high LDL-C levels in a cohort of PWH aged ≥40 years who accessed our HIV outpatient clinic between 1 March 2022 and 31 March 2023. Their 10-year ASCVD risk was calculated on the basis of their age and co-morbidities as recommended by guidelines. High LDL-C levels were defined as those above the "step two" target of their specific ASCVD risk category.

RESULTS

Among the 1404 assessed PWH, who were prevalently male (74.5 %) and Caucasian (85.6 %), and had a median age of 56 years (interquartile range [IQR] 49-61), 295 (21 %) were at very high risk (VHR), 634 (45.2 %) at high-risk (HR), and 348 (24.8 %) not at HR. The overall median LDL-C level was 116 mg/dL (IQR 96-141). Five hundred and sixteen (37 %) were undergoing lipid lowering treatment (LLT), and 650 (46.3 %) failed to achieve any step of their target LDL-C levels.

CONCLUSIONS

Despite the high prevalence of PWH at VHR/HR for ASCVD, LDL-C levels were poorly controlled and LLT was greatly under used.

Evaluation of infectious diseases physicians' attitudes to dyslipidemia management in PLWH

OBJECTIVES

Dyslipidemia is a well-established risk factor for atherosclerotic cardiovascular disease (ASCVD). ASCVD prevalence among people living with HIV (PLWH) is twice that of the general population. This study aimed to evaluate the infectious diseases (ID) physicians' attitudes on dyslipidemia management in PLWH.

METHODS

This observational, cross-sectional study was conducted as online survey among ID physicians between November 2023 and February 2024. An e-mail with the survey link, title and purpose of the study was sent to physicians through the local ID societies. The survey included questions about physicians' demographic characteristics and their attitudes toward treating dyslipidemia in PLWH.

RESULTS

A total of 242 physicians responded to the survey, of whom 59.9% (n = 145) were ID specialists and 40.1% (n = 97) were ID residents. Forty-one percent (n = 100) of physicians reported that they did not follow a guideline, and 26% of physicians reported that they did not use a cardiovascular risk calculator in their clinical practice. Specialists (69%) were more likely than residents (43.3%) to follow clinical guidelines for dyslipidemia management (p < 0.001). Seventy-two percent (n = 174) of physicians doubted the need to treat dyslipidemia, and 73% (n = 177) of physicians were affected by the patient skepticism. Workload and lack of time were identified by 68.6% of physicians as barriers to implementing dyslipidemia guideline recommendations.

CONCLUSION

A considerable number of Turkish ID physicians did not prefer using clinical guidelines for dyslipidemia and ASCVD risk calculators. Statin prescribing of physicians was influenced by workload, lack of time, patient skepticism, and lack of knowledge. Training ID physicians in primary prevention of ASCVD and management of dyslipidemia in PLWH is paramount.

Underprescribing of statin therapy in people with HIV at risk for atherosclerotic cardiovascular disease

DISCLAIMER

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

People with HIV (PWH) are at increased risk for developing atherosclerotic cardiovascular disease (ASCVD). The primary objective of this study was to evaluate adherence to guideline recommendations on statin use in PWH for both primary and secondary ASCVD prevention in a single healthcare institution.

METHODS

A retrospective chart review was performed to evaluate statin use for cardiovascular risk reduction in PWH 40 to 75 years of age at an HIV clinic over a 1-year evaluation period. The study included patients who met one of the 4 criteria for statin therapy defined in the "ACC/AHA Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults." Patient demographics were collected and a 10-year ASCVD risk score was calculated.

RESULTS

A total of 432 PWH were evaluated for statin therapy; 205 patients (47.5%) met criteria for statin therapy. The majority of patients were male, the average age was 58 years, and the average time since HIV diagnosis was 19 years. The mean ASCVD risk score was 14.2%. Only 79 patients (38.5%) who met criteria were prescribed statin therapy, and only 45 (56.9%) were prescribed statin therapy of appropriate intensity. Use of ART pharmacokinetic enhancer was low and did not affect statin prescribing. Multivariable analysis found that age, diabetes, clinical ASCVD, and an appointment with a pharmacist clinician prescriber predicted statin utilization. A high ASCVD risk score (>20%) did not predict statin treatment.

CONCLUSION

Statin prescribing is low in PWH, who are at increased risk for ASCVD. Future research in PWH should focus on improving ASCVD risk assessment and exploring causes for statin underprescribing.
