Factors associated with intention of clinical pharmacists and candidates to provide pharmaceutical care: application of theory planned behaviour.

BACKGROUND: Postgraduate education programs in clinical pharmacy have become widespread in Türkiye. This study aimed to identify factors associated with the intention of Turkish clinical pharmacists and candidates (who were graduates and students of postgraduate clinical pharmacy programs) to provide pharmaceutical care. METHODS: This prospective observational study was conducted between June 2021 and May 2022. After searching relevant studies, an expert panel discussion, translation, cultural adaptation, and a pilot study developed a 52-item Turkish scale based on the Theory of Planned Behavior (TBP). Cronbach alpha for each construct was calculated after an explanatory factor and test-retest reliability analysis. An online survey link was sent to all graduates or candidates of postgraduate clinical pharmacy programs in Türkiye. After univariate regression analysis, the multiple linear regression model was performed. RESULTS: One hundred fifty-six participants completed the survey (response rate: 59.1%). The Cronbach's alpha for attitude (9 items), subjective norm (6 items), perceived behavioural control (5 items), self-efficacy (6 items), intention (11 items) and past behaviour (15 items) were 0.945, 0.720, 0.751, 0.864, 0.934 and 0.955 respectively. The multiple linear regression analysis found a higher score of the subjective norm (p = 0.016), a higher score of self-efficacy (p < 0.001), younger age (p < 0.001) and having PhD (p = 0.038) were associated with increased intention score. CONCLUSIONS: It was shown that higher self efficacy and positive beliefs of their peers and other healthcare professionals were associated with their higher intention score for providing pharmaceutical care. Younger age and having a PhD were other factors associated with their intention to provide pharmaceutical care.

A retrospective study: Can dual ART mitigate the risk of potential drug-drug interactions among PLWH under stable ART?

Background/aim: People living with human immunodeficiency virus (PLWH) are getting older. Age-related comorbidities in PLWH result in polypharmacy and increase the risk for potential drug-drug interactions (pDDIs). This study aimed to evaluate how the rate of pDDIs would change if the treatment of patients receiving different combined antiretroviral therapies (ARTs) were theoretically changed with dolutegravir/lamivudine (DTG+3TC) or cabotegravir/rilpivirine (CAB+RPV). Materials and methods: This study was conducted at the infectious disease outpatient clinic of a university hospital as a follow-up of a previous study. The data of PLWH receiving at least 1 comedication other than antiretrovirals (ARVs) were retrospectively reviewed and analyzed. The Drugs.com/Drug Interactions Checker and University of Liverpool HIV Drug Interactions Checker databases were used to identify pDDIs and their severities. Results: A total of 75 PLWH, of whom 83% were male, with a mean age (± standard deviation) of 46.5 (±12.98) years were included. Polypharmacy was observed in 59 (79%) of the participants; however, with dual ARV options, the probability of polypharmacy was 35 (47%) (p < 0.001). In the Drugs.com database, no significant difference was found in terms of pDDIs between the treatment of current ARTs (64%) and DTG/3TC (%44) (p = 0.06) or CAB/RPV (%64) (p = 0.521). However, in the University of Liverpool database, the current rate of pDDIs (55%) was significantly higher compared to the theoretical treatment of DTG/3TC (40%) (p = 0.029), oral CAB/RPV (48%) (p = 0.003), and injectable CAB/RPV (31%) use (p = 0.006). Conclusion: The results suggest that dual treatment regimens can reduce pDDIs, resulting in better tolerance and probably higher quality of life among PLWH.

Implementation of Pharmacist-Driven Antifungal Stewardship Program in a Tertiary Care Hospital.

Antifungal stewardship (AFS) is recommended to reduce the inappropriate use of antifungal drugs. In this study, the role of AFS in providing appropriate antifungal therapy was evaluated. This study included three periods, consisting of observation, feedback/education, and daily AFS activities. In the observation period, the use of systemic antifungals was evaluated for a baseline measurement of appropriateness. In the second period, monthly meetings were organized to provide feedback and education to physicians regarding antifungal therapy and the rate of adherence to the clinical guidelines. In the final period, a clinical pharmacist participated in daily ward rounds to evaluate the appropriateness of the antifungal therapy. A scoring system for appropriateness was used for comparison between the three periods. Four hundred eighteen episodes of antifungal therapy were evaluated. Baseline demographics of patients were similar in all three periods for age, gender, and the number of comorbidities. The indications for antifungal use were for prophylaxis in 22.7%, Candida infections in 58.6%, and invasive mold infections in 18.7%. During the third period, 157 (78.9%) recommendations were made and 151 (96.2%) were accepted. The overall appropriateness of antifungal use increased significantly for prophylaxis (30.8%, 17.9%, and 46.3%; P = 0.046) and treatment of fungal diseases (27.8%, 32.4%, and 71.9%; P < 0.001) between the first, second, and third periods, respectively. The 30-day mortality was not significantly changed between the three periods (19%, 15.6%, and 27.5%; P = 0.050). Appropriateness in antifungal therapy can be augmented by the integration of an AFS program. A team-based evaluation of fungal infections and assessment of patients by a clinical pharmacist with a therapeutic perspective may help to increase the quality of antifungal therapy.

A case report of tigecycline induced acute pancreatitis in a renal transplant patient and review of the literature: Should we avoid tigecycline in patients on calcineurin inhibitors?

Tigecycline has been approved by the US (United States) Food and Drug Administration in a variety of complicated infections due to its broad-spectrum antibiotic activity. Following phase III trials, the product label was revised and acute pancreatitis was listed as an adverse effect. Its safety profile in special groups such as renal transplant patients is not exactly known. We report the first case of unintentional rechallenge of tigecycline induced pancreatitis in a renal transplant patient. Ten days following the renal transplantation, a 35-year-old patient presented to the clinic with acute rejection. He received anti-thymocyte globulin (ATG) and pulse steroid treatments for rejection. Following the treatment, he developed perianal cellulitis and tigecycline was started. Nine days following initiation of tigecycline he received thrombectomy for his incidental cardiac thrombus. One day after thrombectomy, he developed acute pancreatitis (AP). Thrombectomy was suspected to be the cause of AP. During hospitalization for transplant rejection, tigecycline was re-started for a newly developed complicated abdominal infection. On the third day of the tigecycline re-treatment, he developed a second episode of AP. Following tigecycline withdrawal, his symptoms resolved and serum pancreatic enzymes returned to normal, thus AP was ultimately attributed to tigecycline. This lethal side effect should be kept in mind while treating severe infections in renal transplant recipients.

Pharmacist intervention to improve patients' knowledge and attitude towards hepatitis B infection.

OBJECTIVE: Lack of knowledge/awareness of people living with hepatitis B (PLH) often leads to misinformation and stigmatisation. This study aimed to assess the contribution of the clinical pharmacist (CP)-led education on knowledge of PLH about their disease. METHODS: This prospective, cross-sectional study was carried out between 1 October 2017 and 1 April 2018, at infectious disease and gastroenterology outpatient clinics in a university hospital. All PLH were interviewed face-to-face by a CP and a questionnaire about hepatitis B virus (HBV) knowledge was applied both at the beginning of the study (first interview) and 3 months later (second interview). Correct information was provided verbally to the patients by the CP concerning their incorrect answers during the first interview. A 10% increase in the number of correct answers was targeted for the second interview. RESULTS: A total of 147 PLH with a mean age of 43.05 ± 13.25 years were included in the study (55.8% female). In the first interview, the mean (±standard deviation) number of correct answers was 35.53 ± 9.15 out of 51 questions. In the second interview, correct answers were 48.67 ± 2.74 with an increase of 25.8% (P < .001). In the first interview, the number of correct answers was higher for the following groups: 20-39 age group, people with monthly income of >1081 $ and university graduates. The number of correct answers to all questions but one was elevated (P < .001) in the second interview. Answers to the question "there is a carrier state in chronic hepatitis B (CHB)" did not change (P = .125). CONCLUSION: Significant improvement was observed in the correct answer rate after CP's contribution, therefore as a team member, CP has an important role in improving patients' knowledge and attitude towards HBV infection.

Pretreatment serum uric acid level is not a surrogate marker for the outcome of favipiravir treatment in COVID-19 patients.

BACKGROUND: To the editor, Favipiravir (FVP) was developed against the influenza virus infection and licensed for the treatment of influenza in Japan [1]. In addition to influenza viruses, FVP demonstrates a broad-spectrum activity against many RNA viruses including Ebola, Lassa, rabies, and severe fever with thrombocytopenia [2]. FVP exhibited a comparable in vitro efficacy against SARS-CoV-2 with remdesivir in a cell culture model [3]. DISCUSSION: The authors would like to acknowledge the contributions of numerous physicians, nurses, and healthcare personnel of Hacettepe University's COVID-19 response team for their selfless efforts in follow-up and care of the patients. Authors declare that there is no conflict of interest.

Polypharmacy and drug-related problems among people living with HIV/AIDS: a single-center experience

Background/aim: The HIV-infected population is aging, and the concomitant comorbidities increase the likelihood of polypharmacy. There is a scarcity of data for determining drug-related problems in people living with HIV/AIDS (PLWHA). Materials and methods: This cross-sectional study was carried out between 1 September 2015 and 1 July 2016. All patients underwent a face-to-face interview with a clinical pharmacist. PCNE Classification V 7.0 was used classify incident drug-related problems (DRPs). Results: The mean age of the patients was 40.4 ± 13.06 years. The rate of polypharmacy was 66.1% in patients with comorbidities and 12.3% in those without comorbidities (P < 0.001). DRPs were more prominent in older patients (46 vs. 37 years, P < 0.001), those with longer durations of antiretroviral therapy (ART) (45 vs. 27 months, P = 0.014), and those with lower education levels (P = 0.013). Receiving >3 ART drugs was associated with more DRPs in the logistic regression model (odds ratio: 8.299, 95% confidence interval: 1.924­35.803). Fifty-eight interventions were performed in 45 (24.9%) patients. Clinical pharmacist interventions were performed in 18.9% of patients without polypharmacy and in 38.9% of patients with polypharmacy (P < 0.001). Conclusion: DRPs and polypharmacy are common among elderly PLWHA. More interventions are warranted to boost the quality of life in aging PLWHA.

Tigecycline-associated hypofibrinogenemia: A single center, retrospective, controlled study.

BACKGROUND: Tigecycline-associated hypofibrinogenemia has been reported as an important adverse effect in recent years, but controlled studies minimizing confounding factors are needed. The objective of our study was to assess changes in fibrinogen levels in patients for hospitalization, comparing two antibiotic episodes (tigecycline and other) within the same patients. METHODS: The retrospective, self-controlled case series study was conducted at our University Hospitals. The study compared the change in fibrinogen levels during the patient's hospitalization for tigecycline (TigePer) and another antibiotic period (OtherPer). In addition, bleeding events, bleeding risk (determined by the IMPROVE bleeding risk score), as well as 15- and 30-day mortality rates between TigePer and OtherPer were compared. RESULTS: The study enrolled 50 patients with 100 episodes of antibiotic treatment. The median age (interquartile range) of the patients was 68.5 (21.5) years, and 38 % were female. As compared to OtherPer, TigePer had a statistically significant reduction in fibrinogen levels (p < 0.001), with a hypofibrinogenemia rate of 40 % in TigePer as compared to 2 % in OtherPer (p < 0.001). TigePer demonstrated a significantly higher 15-day mortality rate (p = 0.006). No significant differences were observed between the two periods in terms of bleeding risk, rate of bleeding events, and 30-day mortality rate (p > 0.05). CONCLUSION: Hypofibrinogenemia and other coagulopathies, without associated bleeding events, are more frequently observed in patients receiving tigecycline. Therefore, it is crucial for clinicians to monitor fibrinogen levels during tigecycline use.

Examination of drug removal profiles in patients undergoing therapeutic plasma exchange: A retrospective study.

INTRODUCTION: Therapeutic plasma exchange (TPE) eliminates disease-contributing substances but may also affect drug concentrations. This study aimed to assess the prevalence of prescription drugs removable via TPE by reviewing patient medication histories. METHODS: A retrospective, single-center study was conducted from January 1, 2021 to December 31, 2022. The study included 244 patients undergoing 1087 TPE sessions. Drugs prescribed to patients on TPE days were categorized as "yes" (probably removable), "maybe" (possibly removable), and "no" (unlikely removable) regarding their removability via TPE. RESULTS: Among 3966 prescriptions, 556 (14.0%) were analyzed, with 21.8%, 36.5%, and 41.7% falling into the "yes," "maybe," and "no" categories for removability. Although only 14.0% were categorized, 83.6% of patients received at least one analyzable drug. Among them, 83.8% had at least one potentially removable drug. CONCLUSION: Real-world data highlights the need for caution in drug treatments during TPE to ensure optimal therapeutic outcomes, particularly for specific drugs.

Antimicrobial management in patients undergoing therapeutic plasma exchange: A Cross-Sectional Nationwide Survey.

There is little evidence of antimicrobial elimination via therapeutic plasma exchange (TPE) and no guidelines for antimicrobial optimal dosing in patients undergoing TPE. We aimed to assess current practices and knowledge regarding antimicrobial management during TPE. A structured online survey was conducted from May to November 2023, and physicians were invited to participate through national scientific platforms and professional societies. One hundred five participants completed the survey, of whom 61% were infectious disease physicians, with 68.6% having more than 10 years of experience. That the TPE procedure could significantly affect plasma concentrations of antimicrobial agents was reported by 74.3% of the respondents. Among the physicians, 42.9% suggest antimicrobial dose adjustment, and 38.1% recommend temporarily discontinuing antimicrobial drug administration during TPE. Therapeutic drug monitoring was recommended by 33.3% of the respondents for certain antimicrobials, mainly glycopeptides and aminoglycosides, in patients undergoing concurrent TPE. Furthermore, 59.3% of physicians sometimes consult with another healthcare professional for treatment management, most commonly a pharmacist or a clinical pharmacist and an infectious diseases specialist. The core questions regarding potential drug-, procedure-, and patient-related antimicrobial elimination factors via TPE were responded to accurately by less than half of the physicians. It was clear that they had a lack of clinical practices and knowledge regarding antimicrobial management during TPE. To ensure the therapeutic efficacy of antimicrobials and avoid treatment failure, physicians should improve their practice strategies and consider antimicrobial elimination factors with TPE in this data-poor setting.

Battle of polymyxin induced nephrotoxicity: Polymyxin B versus colistin.

OBJECTIVES: Nephrotoxicity is the most serious and common adverse effect that limits the use of polymyxins. This study compared polymyxin E (colistin) and polymyxin B regarding drug-related nephrotoxicity. METHODS: This study was conducted as a retrospective cohort study in a university hospital between January 2020 and July 2022. Patients older than 18 years and who received colistin or polymyxin B were identified using electronic hospital records. Kidney disease improving global outcome criteria were used for assessing nephrotoxicity. RESULTS: A total of 190 patients, 95 in both groups, were evaluated. The incidence of acute kidney injury during the treatment was higher in the colistin group [52.6% (n = 50) and 34.7% (n = 33), P = 0.013]. In patients who were exposed to high-dose, the rate of nephrotoxicity was higher in patients receiving colistin [25% (n = 3) vs. 76.9% (n = 10); P = 0.017]. Nephrotoxicity was reversible in 64.4% (n = 38) of patients and the reversibility rate was similar (70% and 52.6% for colistin and polymyxin; P = 0.248). In the multivariable analysis, colistin treatment [odds ratio (OR): 3.882, 95% confidence interval (95% CI) = (1.829-8.241)], concomitant vasopressor use (OR = 2.08, CI: 1.036-4.179), and age (OR=1.036, CI: 1.014-1.058) were found to be independent markers of nephrotoxicity. CONCLUSION: Nephrotoxicity was more common in patients receiving high-dose colistin than polymyxin B. Therefore, the use of appropriate doses of colistin is important in terms of preventing nephrotoxicity. In addition, advancing age and concomitant use of vasopressors contribute to polymyxin-related nephrotoxicity.

Compliance with guideline recommendations in the management of patients with hospitalized community-acquired pneumonia.

Compliance with guidelines in the empirical treatment for community-acquired pneumonia (CAP) is very important to increase treatment success and reduce mortality. This study aimed to determine compliance with guideline recommendations for CAP and define the role of the clinical pharmacist (CP). Patients diagnosed with CAP were evaluated retrospectively between January 2018 and January 2020 and prospectively between February 2020 and February 2021. Compliance with guidelines was evaluated according to the local, national (Turkish Thoracic Society), and international (American Thoracic Society and Infectious Disease Society of America, European Society of Clinical Microbiology and Infectious Diseases) guidelines. A total of 751 patients (423 in the retrospective and 328 in the prospective period) were included. It was determined that the 30-day mortality and length of stay were higher in patients who were not treated according to the guidelines. The compliance for empirical treatments was 16.3%-59.1% and 7.8%-30.1% in retrospective and prospective periods, respectively. During the prospective period, a total of 603 recommendations were made by CP, and 578 (95.9%) were accepted and implemented. In the prospective period, treatment duration was shortened, inappropriate fluoroquinolone use was decreased, the switch to oral treatment was increased, and the number of potential drug-drug interactions was decreased (p < 0.001). Compliance with guidelines is essential to be improved to reduce mortality, shorten the length of stay, determine the appropriate antimicrobial duration, and reduce the use of fluoroquinolones and broad-spectrum antibiotics unless necessary. CP intervention contributes to the rational selection of antimicrobials, limiting drug-drug interactions, avoiding toxicities, and compliance with guidelines.

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.

Computational and Experimental Analysis of an In Vitro Microfluidic Experimental Setup on Testing Molteno, Ahmed Valve and Ex-Press Implants and Their Critical Comparisons.

PURPOSE/AIM OF THE STUDY: Researchers have investigated glaucoma drainage devices in various in vitro experimental setups to overcome their disadvantages. In this study, it is aimed to perform in vitro analyses of glaucoma drainage devices that are actively utilized for glaucoma treatment. MATERIALS AND METHODS: A new in vitro experimental setup is constructed and the first outcomes of numerical simulations and experimental trials are shared. Firstly, an in vitro experimental setup is designed and simulated in ANSYS Fluent, then assembled/fabricated using microfluidic equipment. Secondly, computational fluid dynamics results are expressed as pressure losses through an Ahmed Valve implant, a Molteno drainage device, an Ex-Press implant for physiological flow rates. RESULTS: In the scope of this study, Ahmed Valve (valved), Molteno (non-valved), Ex-Press (orbital shunt) implants are examined numerically using computational fluid dynamics tools. Results are compared with in vitro studies of the proposed experimental setup. Poiseuille and Reynolds numbers versus pressure drop characteristics of tested glaucoma drainage devices are also obtained using in vitro microfluidic experimental setup. In the range of 1.6-2.5 µl/min, Ahmed Valve implant created an active and effective pressure drop of 5.6 to 12 mmHg. Ahmed Valve and Molteno showed similar characteristics in terms of Poiseuille and Reynolds numbers variations with pressure drop across implants. Ex-Press, opposing Molteno and Ahmed Valve gave a reciprocal correlation between pressure drop and Po. CONCLUSIONS: High resemblances of pressure drops between computational fluid dynamics results and in vitro microfluidic experimental results proved that the setup will be a better choice compared to syringe pump type setups for testing different glaucoma drainage devices at the same conditions. In conclusion, a new glaucoma drainage device should be equipped with a slimmer but larger end plate and a valve mechanism similar to Ahmed Valve in the perspective of intraocular pressure drop performance.

Integrase inhibitor-based regimens are related to favorable systemic inflammatory index and platecrit scores in people living with HIV (PLWH) up to 2 years.

OBJECTIVES: Despite the advances in antiretroviral treatment (ART), persistent inflammation remained a challenge. We analyzed the inflammatory-score changes through 2-years in people living with HIV (PLWH) treated with different antiretroviral regimes. METHODS: This study was conducted in Hacettepe University HIV/AIDS Treatment and Research Center. PLWH diagnosed between 2014 and 2020 were included. Inflammatory and metabolic markers (CD4/CD8 ratio, C-reactive protein (CRP), Systemic Inflammatory Index (SII), Neutrophil-Lymphocyte Ratio (NLR), Mean Platelet Volume (MPV), Platecrite (PCT), and Low-Density Lipoprotein/High-Density Lipoprotein (LDL/HDL), Platelet-to-Lymphocyte Ratio (PLR) and ARTs were captured from database through 2-years from the diagnosis. The 2-year change (Δ) in markers was calculated and compared by ART type (backbone and 3rd agent). Mann-Whitney-U test and T-test were used for statistical analysis. RESULTS: This study included 205 PLWH; 175 (85.4%) were male, and the mean age was 38.98 (±10.88) years. The number of PLWH with suppressed viremia (<40 HIV-RNA copies/ml) was 164 (80%) at the end of the second year. MPV increased significantly higher among PLWH receiving ABC/3TC compared to PLWH receiving TDF/FTC (p < 0.05). The CD4:CD8 ratio increased, and SII, NLR, LDL/HDL ratios decreased significantly among PLWH treated with integrase strand transfer inhibitors (INSTI) compared with protease inhibitors (PI) and Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) (p < 0.05). CONCLUSIONS: Integrase inhibitor treatment is related to favorable inflammatory marker profile among PLWH in the 2-year follow-up. A favorable inflammatory profile may, in turn, contribute to the prevention of non-communicable diseases (NCD) among PLWH. This study showed that simple, easy-to-calculate markers could be implemented to define ongoing inflammation among PLWH under suppressive ART.
