2024 KSoLA consensus on secondary dyslipidemia.

Elevated blood cholesterol and triglyceride levels induced by secondary causes are frequently observed. The identification and appropriate handling of these causes are essential for secondary dyslipidemia treatment. Major secondary causes of hypercholesterolemia and hypertriglyceridemia include an unhealthy diet, diseases and metabolic conditions affecting lipid levels, and therapeutic side effects. It is imperative to correct secondary causes prior to initiating conventional lipid-lowering therapy. Guideline-based lipid therapy can then be administered based on the subsequent lipid levels.

Treatment for multidrug-resistant tuberculosis: A comparative analysis of programmatic outcome indicators between Buenaventura and other municipalities of Valle del Cauca, Colombia / Tratamiento para tuberculosis resistente a rifampicina o multirresistente: análisis comparativo de indicadores programáticos entre Buenaventura y otros municipios del Valle del Cauca, Colombia

Introduction. Proper management of multidrug-resistant tuberculosis is a prioritized strategy for tuberculosis control worldwide. Objective. To evaluate differences concerning demographic and clinical characteristics and programmatic indicators of Buenaventura patient cohort with confirmed diagnosis of multidrug-resistant tuberculosis, compared to those of the other municipalities from Valle del Cauca, Colombia, 2013-2016. Materials and methods. We conducted an analytical cohort study to compare records of patients older than 15 years with multidrug-resistant tuberculosis included in the Programa de Tuberculosis de Buenaventura (with para-aminosalicylic acid) versus the other municipalities of Valle del Cauca (without para-aminosalicylic). Results. Ninety-nine cases were recorded with a median age of 40 years (IQR = 26 - 53); in Buenaventura, 56% of the patients were women, while in the other municipalities, men predominated with 67%; 95% had health insurance. The most common comorbidity was diabetes (14%). Adverse reactions to antituberculosis medications in Buenaventura were 1.3 times more frequent than in the other municipalities (OR = 2.3; 95% CI = 0.993 - 5.568; p = 0.04). In Buenaventura, the mortality rate was 5% compared to the 15% reported in the other municipalities. Treatment failures were not reported in Buenaventura, but 35% did not continue with the follow-up. Treatment success was higher in Buenaventura (56 %). Conclusion. A strengthened program in Buenaventura presented better programmatic results than those from the other municipalities of Valle del Cauca. Access to molecular tests, availability of shortened treatments, and continuous monitoring to identify adverse reactions to antituberculosis medications are routes for all other control programs.

El acceso a pruebas moleculares, la disponibilidad de tratamientos acortados y el seguimiento continuo para identificar reacciones adversas a medicamentos antituberculosos son un derrotero para todos los programas de control.

Elevated risk of adverse effects from foodborne contaminants and drugs in inflammatory bowel disease: a review.

The global burden of Inflammatory bowel disease (IBD) has been rising over the last decades. IBD is an intestinal disorder with a complex and largely unknown etiology. The disease is characterized by a chronically inflamed gastrointestinal tract, with intermittent phases of exacerbation and remission. This compromised intestinal barrier can contribute to, enhance, or even enable the toxicity of drugs, food-borne chemicals and particulate matter. This review discusses whether the rising prevalence of IBD in our society warrants the consideration of IBD patients as a specific population group in toxicological safety assessment. Various in vivo, ex vivo and in vitro models are discussed that can simulate hallmarks of IBD and may be used to study the effects of prevalent intestinal inflammation on the hazards of these various toxicants. In conclusion, risk assessments based on healthy individuals may not sufficiently cover IBD patient safety and it is suggested to consider this susceptible subgroup of the population in future toxicological assessments.

Reimagining the ADR Alert Card: a novel approach to recurrence prevention in low-cost settings for adverse drug reactions.

OBJECTIVES: Adverse drug reactions (ADRs) are among the leading standalone causes of morbidity and hospitalisation and contribute substantially to an increase in healthcare expenditure. Repeat ADR events, although difficult to quantify, are a recognised problem that lead to preventable suffering for the patient. The current approaches for the prevention of ADR recurrence in low/middle-income countries range from inefficient to non-existent. There is very little literature that focuses on the preventability of ADRs in such settings. This study aimed to develop the ADR Alert Card, an economical innovation designed as a stop gap in preventing ADR recurrence, and to evaluate its utility by validating the system through input from medical professionals. METHODS: The ADR Alert Card was validated and registered with the Copyrights Office of the Government of India. To obtain the opinion of healthcare professionals and gauge the status quo in prevention of ADR recurrence, we conducted an online descriptive cross-sectional study over a period of 6 months. RESULTS: The survey received 218 responses. Demographics varied, ranging across different healthcare specialties and years of experience. Our study found that existing practice in ADR recurrence prevention was inadequate, and most healthcare workers were unaware of an alternative approach. Unique solutions were provided by the respondents, with the majority favouring a card format for preventing recurrence. CONCLUSIONS: After being introduced to the ADR Alert Card, there was an overwhelming consensus on the utility and practicality of this card in preventing ADR recurrence.

Clozapine may consistently protect from suicidal behaviors while other antipsychotics may lack a specific protective effect: a comprehensive VigiBase study interpreted in the context of the prior literature.

BACKGROUND: In the United States clozapine was first approved for treatment-resistant schizophrenia and then for suicidality in schizophrenia psychoses. Systematic reviews support clozapine's anti-suicidal effect, but the forensic literature stresses its lethality during overdoses. RESEARCH DESIGN AND METHODS: Clozapine reports to the international pharmacovigilance database (VigiBase) were analyzed for suicidal ideation, suicide attempts, intentional overdose, and completed suicides from introduction to 1 January 2024. VigiBase uses the information component (IC) as a disproportionality analysis. RESULTS: The clozapine ICs (range: other antipsychotics) were: 1) suicidal ideation IC = 0.570 with IC025 = 0.454 to IC975 = 0.680 (IC = 3.568 for aripiprazole and 1.729 for risperidone), 2) suicide attempt IC = 1.428 with IC025 = 1.323 to IC975 = 1.529 (IC = 4.150 for quetiapine and 2.968 for risperidone), 3) intentional overdose: IC = 0.995 with IC025 = 0.864 to IC975 = 1.120 (IC = 4.080 for quetiapine and 1.957 for aripiprazole), and 4) completed suicide IC = 1.133 with IC025 = 1.026 to IC975 = 1.235 (IC = 4.648 for quetiapine and 2.160 for risperidone). In summary, all clozapine ICs were significantly lower. We found 2391 clozapine-treated patients on the suicidality spectrum (627 cases with suicidal ideation, 752 with suicide attempt, 488 with intentional overdose and 731 with completed suicide) but many were taking other antipsychotics. The most frequent reporting countries were the United States, the United Kingdom, and Croatia. CONCLUSION: This pharmacovigilance study, with all its inherent limitations, provides independent proof, not overlapping with prior literature, that clozapine may have specific strong anti-suicidal effects that do not appear to be present in other antipsychotics. Further VigiBase studies are needed to compare the lethality of an intentional overdose of clozapine (14.3%) with other antipsychotics.

The radiologist's role in detecting systemic anticancer therapy-related interstitial lung disease: an educational review.

Systemic anticancer therapies (SACTs) are the leading cause of drug-induced interstitial lung disease (ILD). As more novel SACTs become approved, the incidence of this potentially life-threatening adverse event (AE) may increase. Early detection of SACT-related ILD allows for prompt implementation of drug-specific management recommendations, improving the likelihood of AE resolution and, in some instances, widening the patient's eligibility for future cancer treatment options. ILD requires a diagnosis of exclusion through collaboration with the patient's multidisciplinary team to rule out other possible etiologies of new or worsening respiratory signs and symptoms. At Grade 1, ILD is asymptomatic, and thus the radiologist is key to detecting the AE prior to the disease severity worsening. Planned computed tomography scans should be reviewed for the presence of ILD in addition to being assessed for tumor response to treatment, and when ILD is suspected, a high-resolution computed tomography (HRCT) scan should be requested immediately. An HRCT scan, with < 2-mm slice thickness, is the most appropriate method for detecting ILD. Multiple patterns of ILD exist, which can impact patient prognosis. The four main patterns include acute interstitial pneumonia / acute respiratory distress syndrome, organizing pneumonia, hypersensitivity pneumonitis, and non-specific interstitial pneumonia; their distinct radiological features, along with rarer patterns, are discussed here. Furthermore, HRCT is essential for following the course of ILD and might help to determine the intensity of AE management and the appropriateness of re-challenging with SACT, where indicated by drug-specific prescribing information. ILD events should be monitored closely until complete resolution. CRITICAL RELEVANCE STATEMENT: The incidence of potentially treatment-limiting and life-threatening systemic anticancer therapy-related interstitial lung disease (SACT-related ILD) events is likely increasing as more novel regimens become approved. This review provides best-practice recommendations for the early detection of SACT-related ILD by radiologists. KEY POINTS: Radiologists are crucial in detecting asymptomatic (Grade 1) ILD before severity/prognosis worsens. High-resolution computed tomography is the most appropriate method for detecting ILD. Drug-induced ILD is a diagnosis of exclusion, involving a multidisciplinary team. Familiarity with common HRCT patterns, described here, is key for prompt detection. Physicians should highlight systemic anticancer therapies (SACTs) with a known risk for interstitial lung diseases (ILD) on scan requisitions.

Drug-Related Glomerular Phenotypes: A Global Pharmacovigilance Perspective.

Introduction: Adverse drug reactions are a significant problem in modern society, stemming from the increase in prescribed medications, over-the-counter drugs, and overall polypharmacy. Glomerular disorders are one of the frequently reported renal conditions associated with medication use. VigiBase is a significant tool for evaluating events associated with drug use, and, to the authors' knowledge, no study has yet assessed this database to identify the primary medications associated with glomerular disorders. Materials and Methods: We collected data from VigiBase for 54 years and evaluated data based on global frequencies, disproportionality (IC025 values), nephrotoxic potential, and physiopathological mechanisms. Results: Over the evaluation period, 33.932.051 spontaneous notifications of adverse drug reactions reported in VigiBase were assessed, from which 106.775 notifications of drug-associated glomerular disorders were extracted. The isolated medications were classified as 'potential nephrotoxins' (47.0%), with 40% of the medications lacking scientific references to report any association with the development of glomerular disorders. Among the evaluated medications, Inotersen (IC025 of 8.3), Penicillamine (IC025 6.8), Bevacizumab (IC025 5.9) and Lenvatinib (IC025 5.4) were identified as having the strongest association with these glomerular disorders. For medications classified as 'non-nephrotoxic', a high disproportionality index was observed, suggesting drugs that might be considered as new potential nephrotoxins. Conclusions: Drug-induced glomerular disorders were significantly associated with medications that had no established nephrotoxic role but demonstrated a high disproportionality index in VigiBase. These newly alleged nephrotoxic drugs warrant further evaluation in dedicated studies to assess their true nephrotoxic potential.

Endoscopic findings of immune checkpoint inhibitor-related gastrointestinal adverse events.

The use of immune checkpoint inhibitors (ICIs) for the treatment of various malignancies is increasing. Immune-related adverse events can occur after ICI administration, with gastrointestinal adverse events constituting a significant proportion of these events. When ICI-related diarrhea/colitis is suspected, endoscopic evaluation is recommended to differentiate it from other etiologies and assess the severity of colitis. The distribution of intestinal inflammation in ICI-related colitis demonstrates a high frequency of extensive colitis (23-86%). However, isolated right-sided colitis (3-8%) and ileitis (2-16%) are less prevalent. Endoscopic findings vary and predominantly encompass features indicative of inflammatory bowel disease, including aphthae, ulcers, diffuse or patchy erythema, mucosal edema, loss of vascular pattern, and friability. The presence of ulcers and extensive intestinal inflammation are associated with a reduced response to treatment. Microscopic inflammation can be observed even in endoscopically normal mucosa, underscoring the need for biopsies of seemingly normal mucosa. Histological findings present with acute/chronic inflammation and occasionally exhibit characteristics observed in inflammatory bowel disease, microscopic colitis, or ischemic colitis. The first-line therapeutic choice for ICI-related diarrhea/colitis with a common terminology criteria for adverse events grade of 2 or above is corticosteroids, whereas infliximab and vedolizumab are recommended for refractory cases.

Changing Gadolinium-Based Contrast Agents to Prevent Recurrent Acute Adverse Drug Reactions: 6-Year Cohort Study Using Propensity Score Matching.

OBJECTIVE: To determine the preventive effect of changing gadolinium-based contrast agents (GBCAs) to reduce the recurrence of GBCA-associated acute adverse drug reactions (ADRs). MATERIALS AND METHODS: This retrospective, observational, single-center study-conducted between January 2016 and December 2021-included 238743 consecutive GBCA-enhanced MRI examinations. We focused on a subgroup of patients who experienced acute GBCA-associated ADRs during any of these examinations and subsequently underwent follow-up GBCA-enhanced MRI examinations up until July 2023. The follow-up examinations involved either the same (non-change group) or different (change group) GBCAs compared to the ones that initially caused the acute ADR. Baseline participant characteristics, generic profile of the GBCAs, administration of premedication, history of prior ADR to iodinated contrast media, and symptoms of GBCA-associated acute ADRs were retrospectively analyzed. Multivariable logistic regression with generalized estimating equations and propensity score matching were used. RESULTS: A total of 1042 instances of acute ADRs (0.44%; 95% confidence interval [CI]: 0.41%-0.46%) were reported. Three-hundred and seventy-three patients underwent GBCA-enhanced MRI examinations after experiencing GBCA-associated acute ADRs within the study period; 31.9% (119/373) reexperienced acute ADRs at any of the follow-up examinations. The ADR recurrence was significantly lower in the GBCA change group than in the non-change group according to multivariable logistic regression (adjusted odds ratio [OR]: 0.35; 95% CI: 0.13-0.90; P = 0.03) and analysis with propensity score matching (14.3% [6/42] vs. 36.9% [31/84], respectively; OR: 0.32, 95% CI: 0.11-0.94; P = 0.04). A history of an ADR to iodinated contrast media (OR: 1.14, 95% CI: 0.68-1.90; P = 0.62) and premedication (adjusted OR: 2.09, 95% CI: 0.93-4.68; P = 0.07) were not significantly associated with GBCA-associated acute ADR recurrence. A separate analysis for recurrent allergic-like hypersensitivity reactions demonstrated similar results (adjusted OR: 0.20, 95% CI: 0.06-0.65; P < 0.01). CONCLUSION: Changing GBCAs may reduce the risk of GBCA-associated acute ADR recurrence.

Medication reviews by emergency department pharmacists in patients hospitalised for an adverse drug event: a cost study.

OBJECTIVE: To perform a cost study of pharmacist-led medication reviews in patients with an acute hospitalization for adverse drug events. METHOD: Emergency department pharmacists performed medication reviews in patients hospitalized after visiting the emergency department for an adverse drug event (ADE). Control patients were hospitalized after an emergency department visit not related to an ADE and received usual care. The costs of the intervention were labour costs of the junior emergency department pharmacist and the cost savings consisted of costs of medication that was stopped or reduced during six months after the intervention. Sensitivity analyses were performed to evaluate different scenarios. RESULTS: In the intervention group (n = 104) 113 medication changes led to stopping or reducing medication, accounting for averted costs of €22,850. In the control group (n = 112) 39 medication changes led to stopping or reducing medication, accounting for averted costs of €299. The mean labour costs of the intervention were €138 per patient, resulting in saved costs of €61 per patient per six months. Sensitivity analyses showed that if the intervention would be performed by a senior clinical pharmacist, there are no cost savings (€-21), if parts of the intervention would be executed by pharmacy technicians (e.g. administrative tasks), cost savings would be augmented to €87, if outliers in costs associated with medication reduction would be excluded, there are no cost savings (€-35) and if the costs of reduced medication were extrapolated to one year, cost savings would be €260. CONCLUSION: In this study, medication reviews by junior emergency department pharmacists in patients hospitalized after an emergency department visit for an ADE lead to a cost reduction over a six month period. TRIAL REGISTRATION: The main study is registered on the ISRCTN registry with trial ID ISRCTN12506329 on 06-03-2022.

Toxic-metabolic encephalopathy induced by metronidazole and disulfiram: classics never die.

A 53-year-old male with recovering alcohol dependency, diagnosed with bipolar disorder and recurrent episodes of diverticulitis, came to the emergency department with disorientation and confusion after 3 days of treatment with metronidazole 250 mg/12 hours and ciprofloxacin 500 mg/12 hours for acute diverticulitis. In the hospital emergency department, he presented moments of agitation, fluctuations of attitude, increased basal tremor, with rhythmic movement of the left arm and leg, as well as generalised rigidity with an episode of tonic-clonic seizure of 1.5-2 min duration. After performing different diagnostic tests, significant brain findings were ruled out. The pharmacy department recommended the discontinuation of one of the two drugs. As a result, the on-call doctor adjusted the patient's treatment: disulfiram and previous antibiotic therapy (metronidazole and ciprofloxacin) were discontinued, and amoxicillin/clavulanic acid 2 g/8 hour was prescribed instead. The patient progressed well and fully recovered.

Acyclovir-induced psychiatric and renal adverse effects in a diabetic patient: A case report.

Acyclovir can cause neurotoxicity and nephrotoxicity, especially in diabetic patients with renal impairment. Consider acyclovir dose adjustment, close monitoring of kidney function, and hemodialysis as a potential therapeutic option in such cases.

When Medications Backfire: A Case Report of Rifaximin-Induced Rhabdomyolysis in a Kidney Transplant Patient.

Rhabdomyolysis involves significant skeletal muscle injury and destruction, which can be triggered by trauma, intense physical activity, heat, prolonged immobility, certain medications, and endocrine disorders. Rhabdomyolysis in renal transplants can be more complicated, and the prognosis is not well known, especially in the context of coexisting rejection. We present a case of rifampicin-induced rhabdomyolysis with superimposed acute cellular rejection in a kidney transplant patient.

Pharmacotherapy assessment and adverse drug reactions in older patients admitted to intensive care.

INTRODUCTION: Older patients are more susceptible to medication use, and physiological changes resulting from aging and organic dysfunctions presented by critically ill patients may alter the pharmacokinetic or pharmacodynamic behavior. Thus, critically ill older people present greater vulnerability to the occurrence of pharmacotherapeutic problems. OBJECTIVE: To evaluate pharmacotherapy and the development of potential adverse drug reactions (ADRs) in older patients admitted to an intensive care unit (ICU). METHOD: A cohort study was conducted in an ICU for adults of a Brazilian University Hospital during a 12-month period. The patients' pharmacotherapy was evaluated daily, considering the occurrence of ADRs and drug-drug interactions (DDIs), the use of potentially inappropriate medications (PIMs) for older people, and the pharmacotherapy anticholinergic burden (ACB). A trigger tool was used for active search of ADRs, with subsequent causality evaluation. PIM use was evaluated by means of the Beers criteria and the STOPP/START criteria. The ABC scale was employed to estimate ACB. The Micromedex® and Drugs.com® medication databases were employed to evaluate the DDIs. RESULTS: The sample of this study consisted of 41 patients, with a mean age of 66.8 years old (±5.2). The 22 triggers used assisted in identifying 15 potential ADRs, and 26.8% of the patients developed them. The mean estimated ACB score was 3.0 (±1.8), and the patients used 3.1 (±1.4) and 3.3 (±1.6) PIMs according to the Beers and the STOPP criteria, respectively. A total of 672 DDIs were identified, with a mean of 16.8 (±9.5) DDIs/patient during ICU hospitalization. Our findings show an association between occurrence of ADRs in the ICU and polypharmacy (p=.03) and DDIs (p=.007), corroborating efforts for rational medication use as a preventive strategy. CONCLUSIONS: Using tools to evaluate the pharmacotherapy for older people in intensive care can assist in the recognition and prevention of pharmacotherapeutic problems, with emphasis on the identification of ADRs through the observation of triggers and subsequent causality analysis.

Effectiveness of self-reported management program of cancer patients.

Objective: This study aimed to analyze the effect of Smart Cancer Care program on the quality of life and ease of chemotherapy continuation in cancer patients and the effect of additional tele-management on frequency of use and satisfaction with the Smart Cancer Care program. Methods: 'Smart Cancer Care' is a mobile program that allows cancer patients undergoing chemotherapy to report symptoms of adverse events and receive remote management. In this study, patients were randomly assigned to three groups: Group A, who received only classical face-to-face management; Group B, who used the Smart Cancer Care program as addition; and Group C, who used the Smart Cancer Care program and received telephone management. After 12 weeks of follow-up, the effectiveness of using the Smart Cancer Care program was analyzed by examining the quality of life, ease of maintaining chemotherapy, and unplanned hospital visits in each group. The frequency of use and satisfaction with the Smart Cancer Care program were also analyzed. Results: Cancer patients who used the Smart Cancer Care program had 1.93-fold (1.15-3.25) higher overall quality of life than those who did not. This became 2.33-fold (1.34-4.04) higher when phone care was added. Patients with tele-management were significantly more likely to use the Smart Cancer Care program (odds ratio (OR) = 25.80; 95% confidence interval (CI), 11.28-58.97). Conclusions: A mobile self-reported management program has a positive effect on the quality of life of cancer patients undergoing chemotherapy. Tele-management is conducive to active and effective use of this program.

Assessment of centanafadine in adults with ADHD: a matching adjusted indirect comparison versus methylphenidate hydrochloride extended release (Concerta).

OBJECTIVE: To compare safety and efficacy of centanafadine versus methylphenidate hydrochloride extended release (ER; Concerta) in adults with ADHD. METHODS: Without head-to-head trials, anchored matching-adjusted indirect comparisons (MAIC) of adverse event rates reported across trials and mean change from baseline in Adult ADHD Investigator Symptom Rating Scale (AISRS) score between centanafadine and methylphenidate hydrochloride ER were conducted. Pooled patient-level data from two centanafadine trials (NCT03605680/NCT03605836) and aggregate data from one published methylphenidate hydrochloride ER trial (NCT00937040) were used. Characteristics of individual patients from the centanafadine trials were matched to aggregate baseline characteristics from the methylphenidate hydrochloride ER trial using propensity score weighting. A sensitivity analysis assessed the robustness of the results to the capping of extreme weights (i.e. >99th percentile). RESULTS: Compared with methylphenidate hydrochloride ER, centanafadine was associated with significantly lower risk of dry mouth (risk difference [RD] in percentage points: -11.95), initial insomnia (-11.10), decreased appetite (-8.05), anxiety (-5.39), palpitations (-5.25), and feeling jittery (-4.73) though a significantly smaller reduction in AISRS score (4.16-point). In the sensitivity analysis, the safety results were consistent with the primary analysis but there was no significant difference in efficacy between centanafadine and methylphenidate hydrochloride ER. CONCLUSION: In this MAIC, centanafadine had better safety and possibly lower efficacy than methylphenidate hydrochloride ER. While safety results were robust across analyses, there was no efficacy difference between centanafadine and methylphenidate hydrochloride ER in the sensitivity analysis. Considering its favorable safety profile, centanafadine may be preferred among patients for whom treatment-related adverse events are a concern.
