The decline in kidney function after heart transplantation and its impact on survival.

BACKGROUND: Evidence of decline in native renal function after heart transplantation (HTx) in the Asian population is limited. This study determined the incidence and risk factors associated with declining kidney function after HTx and its impact on survival. METHODS: A retrospective study of consecutive adult heart transplant patients was conducted in a single center between 2010 and 2020. The decline in kidney function was defined as the presence of one of the following criteria, including a ≥ 40% decline in eGFR, absolute value <15 mL/min/1.73 m2 (calculated by the CKD-EPI method), doubling of serum creatinine, or dialysis. RESULTS: A total of 79 patients (77% male, mean age 44.5 ± 11.53 years, with a mean eGFR at discharge from the heart transplant admission of 87.9 ± 25.48 mL/min/1.73 m2 ) were included. During the median follow-up of 42 months, the rate of decline in eGFR was 3.9 mL/min/1.73 m2 per year, with a cumulative probability of decline in kidney function of 22% at 1 year and 43% at 5 years. The need for dialysis was 2.5% at 1 year and 5% at 5 years. The decline in kidney function within 1 year after discharge (hazard ratio (HR), 22.24; p = .007) and pre-HTx diabetes mellitus (DM) (HR, 8.99; p = .034) were independently associated with the need for dialysis. Post-HTx dialysis predicted all-cause mortality (HR, 4.47; p = .017). CONCLUSIONS: Approximately 20% of HTx patients developed a decline in kidney function within 1 year after discharge. These individuals and pre-HTx DM patients needed preventive measures to prevent progression to chronic dialysis, which impacted survival. (thaiclinicaltrials.org number, TCTR20230620004).

Prevalence and Associated Factors of Drug-Related Problems Among Older People: A Cross-Sectional Study at King Chulalongkorn Memorial Hospital in Bangkok.

BACKGROUND AND OBJECTIVE: The use of multiple medications and altered pharmacokinetics/pharmacodynamics may lead to drug-related problems in members of the older population. The aim of this study is to evaluate the prevalence of, and factors related to, drug-related problems in older urban-living Thai people. METHODS: We conducted a cross-sectional study involving 466 participants (aged ≥ 65 years) whose first-time health screening at the Geriatric Excellence Center, King Chulalongkorn Memorial Hospital, Bangkok was between May and October 2019. Participants were interviewed and assessed for drug-related problems by clinical pharmacists. RESULTS: In total, 54.5% (254) of the participants were aged 65-69 years and 77.0% (359) of the participants were women. Of the participants, 56.7% had three or more health conditions such as hyperlipidemia (62%), hypertension (46%), and cataract (18%). Fifty-five percent of the participants took five or more health products (polypharmacy) and 16% took ten or more products on a regular basis. Of the 2633 products used, 68% were prescription drugs and 32% were over-the-counter products. The prevalence of drug-related problems according to the criteria suggested by Cipolle-Strand-Morley (2012) was 63.3% (587 drug-related problems). Most of the problems came from: (a) non-adherence (28.6%); (b) needs for additional drug therapy (26.4%); and (c) adverse drug reactions (17.4%). Factors associated with drug-related problems were polypharmacy (odds ratio 2.50, 95% confidence interval 1.60-3.89) and multiple comorbidities [three or more conditions] (odds ratio 2.20, 95% confidence interval 1.41-3.43). CONCLUSIONS: The prevalence of drug-related problems in urban-living older people at King Chulalongkorn Memorial Hospital in Bangkok was high. Polypharmacy and multiple comorbidities were significantly related to drug-related problems. To decrease the number of drug-related problems, pharmacists should collaborate with healthcare teams and suggest how to correctly reduce the number of health products being consumed by older people.
