Effect of the combination of diuretics, renin-angiotensin-aldosterone system inhibitors, and non-steroidal anti-inflammatory drugs or metamizole (triple whammy) on hospitalisation due to acute kidney injury: A nested case-control study.

PURPOSE: Concomitant use of diuretics, renin-angiotensin-aldosterone system (RAAS) inhibitors, and non-steroidal anti-inflammatory drugs (NSAIDs) or metamizole, known as 'triple whammy' (TW), has been associated with an increased risk of acute kidney injury (AKI). Nevertheless, there is still uncertainty on its impact in hospitalisation and mortality. The aim of the study was to analyse the association between exposure to TW and the risk of hospitalisation for AKI, all-cause mortality and the need for renal replacement therapy (RRT). METHODS: A case-control study nested in a cohort of adults exposed to at least one diuretic or RAAS inhibitor between 2009 and 2018 was carried out within the Pharmacoepidemiological Research Database for Public Health Systems (BIFAP). Patients hospitalised for AKI between 2010 and 2018 (cases) were matched with up to 10 patients of the same age, sex and region of Spain who had not been hospitalised for AKI as of the date of hospitalisation for AKI of the matching case (controls). The association between TW exposure versus non-exposure to TW and outcome variables was analysed using logistic regression models. RESULTS: A total of 480 537 participants (44 756 cases and 435 781 controls) were included (mean age: 79 years). The risk of hospitalisation for AKI was significantly higher amongst those exposed to TW [adjusted odds ratio (aOR) 1.36, 95% confidence interval (95%CI) 1.32-1.40], being higher with current (aOR 1.60, 95%CI 1.52-1.69) and prolonged exposure (aOR 1.65, 95%CI 1.55-1.75). No significant association was found with the need of RRT. Unexpectedly, mortality was lower in those exposed to TW (aOR 0.81, 95%CI 0.71-0.93), which may be influenced by other causes. CONCLUSION: Vigilance should be increased when diuretics, RAAS inhibitors, and NSAIDs or metamizole are used concomitantly, especially in patients at risk such as elderly patients.

Impact of COVID-19 Pandemic in Antibiotic Consumption in Navarre (Spain): An Interrupted Time Series Analysis.

On 11 March 2020, the World Health Organization declared coronavirus disease 19 (COVID-19) a global pandemic. This exceptional situation changed the world not only in terms of mortality and morbidity, but also in terms of epidemiology and health system resources consumption. The objective of this work was to analyze the consumption of antibiotics during the period around the pandemic in our region. A drug utilization study was performed comparing the antibiotic consumption in the community during the years 2018, 2019, 2020, and 2021. Quarterly antibiotic use (defined daily doses (DDD) per 1000 inhabitants per day (DID)) and number of patients treated were the outcomes. Interrupted time series regression analysis was performed to estimate the statistical significance of the change in level of consumption before and after the COVID-19 pandemic. The drop of global antibiotic consumption was statistically significant, both in number of patients and in DID when analyzing pre-pandemic period versus pandemic period. The use of strategic antibiotics for respiratory infections such as amoxicillin, amoxicillin-clavulanic acid, and levofloxacin also decreased significantly. Seasonal pattern of use of antibiotics disappeared due to the global measures imposed over the world to work against COVID-19.

Statin-induced autoimmune myopathy: a case report.

Statins are widely used in the treatment of hypercholesterolemia. Muscle weakness and elevated creatine kinase (CK) are frequent side effects of statins with an incidence of about 15%. Statin-associated myopathy is more common in people who receive multiple drugs, the elderly or women but the mechanism underlying it is still unclear. These symptoms generally improve after drug discontinuation. However, there is a type of autoimmune mediated myopathy characterised by the persistence of muscle weakness and CK elevation after stopping statins. Herein, we discuss a case of autoimmune myopathy associated with statin exposure and responsive to immunossupresive drugs. The increased use of statins in recent years raises the importance of acquaintance with this disease in clinical practice.

Combination of ceftaroline and daptomycin as treatment for complicated osteomyelitis.

Osteomyelitis is an infection involving bone. Staphylococcus aureus is the pathogen most frequently implicated; less frequently involved are other gram-positive organisms, such as Staphylococcus epidermidis, and also gram-negative organisms. The antibiotic of choice for treatment of osteomyelitis caused by methicillin-resistant staphylococci (MRS) is vancomycin, although other alternatives such as daptomycin or teicoplanin are also considered. Osteomyelitis caused by MRS can be difficult to treat safely and effectively. This case report describes the successful use of daptomycin combined with ceftaroline for the treatment of osteomyelitis caused by methicillin-resistant S. epidermidis (MRSE) in a 54-year-old woman, emphasising the clinical pharmacist's role in antimicrobial stewardship programmes. This alternative combination has been studied in the treatment of methicillin-resistant S. aureus (MRSA), but it may also be useful in MRSE.

Bullous pemphigoid induced by ustekinumab: a case report.

A possible case of bullous pemphigoid (BP) that developed during treatment with ustekinumab is reported. Ustekinumab is a human monoclonal antibody found in pathologies such as psoriasis, which works by inhibiting the activity of interleukin-12 and interleukin-23. We describe the case of a 75-year-old woman who presented with new onset of erythematous and bullous lesions 5 days after receiving a fifth dose of ustekinumab. The patient was treated with corticosteroids and dapsone, whereupon the lesions disappeared. Ustekinumab was withdrawn. Currently the patient remains asymptomatic. In addition, the histopathological and immunofluorescence findings confirmed the diagnosis of BP. Three causality algorithms were applied and revealed a probable causal relationship. There may be a causal relationship between the use of ustekinumab and BP. This association should be taken into account by physicians when prescribing and reviewing drug therapies.

Ulcerative colitis induced by ixekizumab: a case report.

A possible case of ulcerative colitis (UC) developed during treatment with ixekizumab is reported. Ixekizumab is a human monoclonal antibody approved for chronic plaque psoriasis that works by blocking interleukin-17 (IL-17). Cytoquines, such as IL-17, may be involved in the pathophysiology of psoriasis and inflammatory bowel diseases. We describe the case of a 76-year-old woman who presented with an episode of acute self-limited colitis after receiving ten doses of ixekizumab. It was resolved after treatment withdrawal. A re-challenge was done after 3 months and symptoms returned. Colonoscopy results confirmed the diagnosis of UC. Symptoms remitted after drug discontinuation and treatment with corticosteroids. Four months after stopping ixekizumab, she remains asymptomatic and she is being treated with guselkumab with adequate response. The Naranjo algorithm revealed a probable causal relationship.This adverse event should be taken into account by physicians and pharmacists before prescribing or reviewing therapies in order to improve patients' safety.

Alcohol intake reduction for controlling hypertension.

BACKGROUND: High blood pressure constitutes one of the leading causes of mortality and morbidity all over the world. At the same time, heavy drinking increases the risk for developing cardiovascular diseases, including cardiomyopathy, hypertension, atrial arrhythmias, or stroke. Several studies have already assessed specifically the relationship between alcohol intake and hypertension. However, the potential effect on blood pressure of alcohol intake reduction interventions is largely unknown. OBJECTIVES: To assess the effect of any intervention to reduce alcohol intake in terms of blood pressure decrease in hypertensive people with alcohol consumption compared to a control intervention or no intervention at all. To determine additional effects related to mortality, major cardiovascular events, serious adverse events, or quality of life. SEARCH METHODS: The Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials up to June 2020: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 5, 2020), MEDLINE Ovid (from 1946), MEDLINE Ovid Epub Ahead of Print, and MEDLINE Ovid In-Process, Embase Ovid (from 1974), ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. Trial authors were contacted when needed and no language restrictions were applied. SELECTION CRITERIA: We included randomised controlled trials with minimum 12 weeks duration and including 50 or more subjects per group with quantitative measurement of alcohol consumption and/or biological measurement of the outcomes of interest. Participants were adults (16 years of age or older) with systolic blood pressure (SBP) greater than 140 mmHg and diastolic blood pressure (DBP) greater than 90 mmHg, and SBP ≥ 130 or DBP ≥ 80 mmHg in participants with diabetes. We included any intervention implemented to reduce their alcohol intake. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed search results and extracted data using standard methodological procedures adopted by Cochrane. MAIN RESULTS: A total of 1210 studies were screened. We included one randomised controlled trial involving a total of 269 participants with a two-year follow-up. Individual patient data for all participants were provided and used in this review. No differences were found between the cognitive-behavioural intervention group and the control group for overall mortality (RR 0.72, 95% CI 0.16 to 3.17; low-certainty evidence), cardiovascular mortality (not estimable) and cardiovascular events (RR 0.80, 95% CI 0.36 to 1.79; very low-certainty evidence). There was no statistical difference in systolic blood pressure (SBP) reduction (Mean Difference (MD) -0.92 mmHg, 95% confidence interval (CI) -5.66 to 3.82 mmHg; very low-certainty evidence) or diastolic blood pressure (DBP) decrease (MD 0.98 mmHg, 95% CI -1.69 to 3.65 mmHg; low-certainty evidence) between the cognitive-behavioural intervention group and the control group. We also did not find any differences in the proportion of subjects with SBP < 140 mmHg and DBP < 90 mmHg (Risk Ratio (RR) 1.21, 95% CI 0.88 to 1.65; very low-certainty evidence). Concerning secondary outcomes, the alcohol intake was significantly reduced in the cognitive-behavioural intervention compared with the control group (MD 191.33 g, 95% CI 85.36 to 297.30 g). We found no differences between the active and control intervention in the proportion of subjects with lower-risk alcohol intake versus higher-risk and extreme drinkers at the end of the study (RR 1.04, 95% CI 0.68 to 1.60). There were no estimable results for the quality of life outcome. AUTHORS' CONCLUSIONS: An intervention for decreasing alcohol intake consumption did not result in differences in systolic and diastolic blood pressure when compared with a control intervention, although there was a reduction in alcohol intake favouring the active intervention. No differences were found either for overall mortality, cardiovascular mortality or cardiovascular events. No data on serious adverse events or quality of life were available to assess. Adequate randomised controlled trials are needed to provide additional evidence on this specific question.

Telmisartan-induced sprue-like enteropathy: a case report.

A possible case of sprue-like enteropathy (SLE) induced by the use of telmisartan is reported. Telmisartan is an angiotensin-receptor II blocker (type 1) used for the treatment of hypertension. Several cases of SLE associated with olmesartan and other drugs of the same group have been reported. In all cases, SLE resolved following therapy withdrawal. We describe the case of an 80-year-old woman who presented with diarrhoea and abdominal pain. In the past 5 years she had been treated with telmisartan 40 mg once a day for hypertension, so we hypothesised that symptoms might be caused by telmisartan. After treatment discontinuation, diarrhoea disappeared. Three causality algorithms were applied and revealed a possible or likely causal relationship. At present, the patient remains asymptomatic. There is a causal relationship between the use of telmisartan and SLE. This association should be taken into account by physicians when prescribing and reviewing drug therapies.

Influence of Sex, Age, and Weight on Levetiracetam Pharmacokinetics.

BACKGROUND: Levetiracetam (LEV) is a second-generation antiepileptic drug extensively used in therapeutics. The aim of this study was to evaluate the influence that sex, age, and weight exert on LEV pharmacokinetics in clinical practice. METHODS: We conducted a 6-year retrospective observational study. Patients were classified in subgroups according to sex, weight (normal range, overweight, and obese), and age (young adult: 16-30 years old, middle-aged adult: 31-50 years old, advanced adult: 51-64 years old, and elderly adult: ≥65 years old). We compared LEV apparent oral clearance (LEV CL/F) between the subgroups. RESULTS: A total of 238 LEV basal serum concentrations (LEV C0) corresponding to 156 patients were identified. Significant differences were observed in LEV CL/F between males and females when LEV CL/F was expressed as L/h [mean (SD): 4.79 (1.84) L/h in males versus 4.13 (1.64) L/h in females; P < 0.001]. These differences were not significant when LEV CL/F was normalized by weight [mean (SD): 60.64 (24.90) mL/h/kg in males versus 64.10 (28.87) mL/h/kg in females; n.s.]. Weight in females was 17% lower compared with males. A progressive reduction in LEV CL/F was observed with increasing age, in a proportion that was similar to the decline in renal function. The elderly patients presented 30% lower LEV CL/F (mL/h/kg) and 43% lower creatinine clearance (CCr) in comparison with adults. No statistically significant differences were observed in LEV CL/F calculated in L/h between weight subgroups. However, when LEV CL/F was expressed in mL/h/kg, a progressive reduction was observed [normal weight: 72.21 (28.97); overweight: 57.84 (25.38); obese: 49.45 (14.50); P < 0.001]. A significant and positive correlation between CCr and LEV CL/F was observed, confirming the important role of the renal function in LEV CL/F. The CCr increased in each sex group when weight increased; however, LEV CL/F (L/h) remained constant. CONCLUSIONS: Sex, age, and weight affect LEV pharmacokinetics, having an impact on the individual dosage regimen needed to achieve the therapeutic objective. Sex is a conditioning factor of LEV CL/F, although its influence is principally due to the weight. LEV CL/F decreases with advancing age, proportionally to the decline in renal function. It is confirmed that LEV dosage per body weight is not required, and prescribing higher doses of LEV in obese patients is not justified. These data suggest that routine LEV therapeutic drug monitoring in the elderly patients, patients with renal dysfunction, and obese patients is indicated.

Influence of Comedication on Levetiracetam Pharmacokinetics.

BACKGROUND: To evaluate the effect of concomitant antiepileptic therapy on levetiracetam (LEV) pharmacokinetics. METHODS: A 6-year retrospective observational study. Patients were grouped according to the antiepileptic drug used as concomitant medication: group A, LEV in monotherapy; group B, LEV + enzyme-inducing antiepileptic drugs (EIAEDs); and group C, LEV + non-enzyme-inducing antiepileptic drugs (NEIAEDs). Apparent oral levetiracetam clearance (LEV CL/F) and basal serum levetiracetam concentrations (LEV C0) were compared among the different groups by analysis of variance. RESULTS: A total of 330 LEV C0 corresponding to 205 patients (56% men) were identified. The mean (±SD) of LEV CL/F in group A (n = 180), B (n = 92), and C (n = 58) was 4.41 ± 2.06 L/h, 7.23 ± 3.72 L/h, and 4.87 ± 1.65 L/h, respectively. EIAEDs increased LEV CL/F (L/h) by 64% compared with the monotherapy group and by 48% compared with the NEIAEDs group. The greatest induction in LEV CL/F, compared with the LEV monotherapy group, was observed with carbamazepine, followed by oxcarbazepine and phenobarbital, and was increased by 81%, 64%, and 44%, respectively. LEV C0 values were significantly lower in the EIAEDs group than in the monotherapy group (17.30 ± 7.77 versus 20.08 ± 9.69 mcg/mL; P = 0.038) or indeed the NEIAEDs group (17.30 ± 7.77 versus 20.49 ± 9.46 mcg/mL; P = 0.027). CONCLUSIONS: Comedication with EIAEDs increased LEV CL/F by more than 40%, whereas carbamazepine had the greatest inducing potency with LEV CL/F being 81% higher than that of the monotherapy group. These data suggest that monitoring LEV serum concentration during polytherapy with EIAEDs is indicated.
