Pharmacogenetic biomarkers of response in Crohn's disease.

Crohn's disease (CD) is a chronic condition, which affects the immune system. It can also affect any part of the digestive tract and be associated with external manifestations. The causes of the disease remain unknown, although it seems to be the result of a combination of factors, such as genetic predisposition, environment, lifestyle and the composition of the microbiota, among others. The treatment protocol begins with a change in eating and smoking habits, and is continued with different lines of treatment, including corticosteroids, immunomodulators and biologic therapy (infliximab and adalimumab), which have shown differences in response among patients, especially with biologic treatment. Several studies have considered the possibility that these differences in response are caused by the genetic variability of patients. Many genes have been investigated as potential predictors of response to biological drugs, such as ADAM17, ATG16L1, EMSY, CASP9, CCNY, CNTN5, FASLG, FCGR, NOD2, PTGER4, IL13, IL1B, IL27, IL11, IL17F, TNF and TNFR genes. In this review, we will gather the information on influence of gene polymorphisms investigated to date on response to biological drugs in CD patients.

Negative outcomes associated with medication in patients with chronic atrial fibrillation who present at the emergency department.

WHAT IS KNOWN AND OBJECTIVE: Medication is the main treatment option for patients with chronic atrial fibrillation. However, medication can have negative effects. We aimed to detect negative outcomes associated with medication that led to patients with chronic atrial fibrillation presenting themselves to hospital emergency departments. We assessed the severity of those outcomes and comment on whether they could have been avoided. METHODS: This descriptive, cross-sectional study included all patients with chronic atrial fibrillation who attended the emergency department of our tertiary hospital. We used the Dader method to identify and evaluate the negative outcomes associated with medication through interviews with patients and scrutiny of the clinical charts. RESULTS AND DISCUSSION: Of the 198 eligible patients who presented at the emergency department, 134 (67·7%) did so because of negative outcomes associated with medication (41% related to necessity, 32·1% to effectiveness and 26·9% to safety); 67·9% of those negative outcomes could have been avoided. In terms of severity, 6·7% were mild, 31·3% moderate, 51·5% severe and 10·4% fatal. The Anatomical Therapeutic Chemical Classification anatomical group most frequently associated with negative outcomes was the cardiovascular system, followed by blood/blood-forming organs. WHAT IS NEW AND CONCLUSION: A high percentage of patients with chronic atrial fibrillation presenting at hospital emergency departments had negative outcomes associated with medication. Some led to deaths. More than half of these were severe, and most could have been avoided.

A multidisciplinary consensus statement on the optimal pharmacological treatment for metastatic hormone-sensitive prostate cancer.

Androgen deprivation therapy (ADT) is the mainstay treatment for metastatic hormone-sensitive prostate cancer (mHSPC). The addition of docetaxel or new hormone therapies (abiraterone, apalutamide, or enzalutamide) improves overall survival and is currently the standard of care. However, the decision on the specific regimen to accompany ADT should be discussed with the patient, considering factors such as possible associated toxicities, duration of treatment, comorbidities, patient preferences, as there is no sufficient evidence to recommend one regimen over the other in most cases. This paper summarizes the evidence on the management of mHSPC and provides consensus recommendations on the optimal treatment in combination with ADT in mHSPC patients, with special attention to the patient's clinical profile.

Validation of a method for recording pharmaceutical interventions.

WHAT IS KNOWN AND OBJECTIVE: The validation of a method for recording pharmaceutical interventions measures the instrument's ability to provide consistent values when the same analysis is performed several times. Our aim was to validate the inter-rater reliability of the method used to record pharmaceutical interventions in our hospital. METHODS: We recorded interventions in a database, entering variables related to the patient, treatment and impact of the recommendation. We also recorded the type, cause and clinical significance of the negative outcome associated with use of the medicinal product (NOM). Twenty interventions performed during a 3-year study period (2007-2009) were randomly tested for consistency to analyse the kappa (κ) coefficient statistic of the recommendations as coded by nine senior and junior clinical pharmacists. RESULTS AND DISCUSSION: There were 87·8% global consistency for NOM cause, 66·1% for intervention impact and 95·0% for NOM type. Agreement was substantial for 'intervention reasons', with a κ value of 0·74 (95%CI 0·61-0·87), fair for 'intervention impact', with a κ value of 0·24 (95%CI 0·15-0·32) and excellent for 'NOM type', with a κ value of 0·87 (95%CI 0·71-1·00), respectively. Our results are globally good, especially with regard to the analysis of intervention reasons and NOM type, which matches other authors' findings. Furthermore, our validation method is suitable for recording and considering the impact of pharmaceutical interventions. WHAT IS NEW AND CONCLUSION: We describe a systematic method for clinical pharmacists to record their activities and assess their value. This methodology should help in the development of clinical pharmacy in Spain and should be translatable to other settings.

[Dispensing standardised medication in a tertiary hospital emergency department]. / Dispensación de medicación protocolizada en un servicio de urgencias de un hospital de tercer nivel.

INTRODUCTION: It is well-known that there is a lack of continuity in care received from the emergency department, as patients have to visit their physician in order to receive official prescriptions. A programme has been designed that aims to provide these patients with a therapeutic protocol to ensure that they are treated, thus improving coordination between the Hospital Emergency Department and Primary Care. METHODS: Creating a multidisciplinary team. Choosing the diagnoses that are most common in the emergency department and which are likely to be standardised. Developing treatment protocols, adapting them to the diagnoses selected. Creating a database, collecting, processing and analysing data. Designing satisfaction surveys, for patients given a therapeutic protocol, and for practitioners involved in the programme. RESULTS: Treatment protocols were assigned to the nine most common diagnoses in the emergency department, with three-day treatment. The selected diagnoses covered 19.5% of the population attending the Emergency Department. A treatment protocol was dispensed to 17.3% of patients with the selected diagnoses. Patient satisfaction was excellent. Physicians approved of the programme, but the treatment protocol prescription did not agree with the degree of approval. CONCLUSIONS: The results show that the programme was excellently accepted by both patients and physicians, although the coverage given to the needs identified was lower than required.

[Compliance of prescriptions for chronic obstructive pulmonary disease patients given upon hospital discharge]. / Adecuación de la prescripción al alta hospitalaria en pacientes con enfermedad pulmonar obstructiva crónica.

OBJECTIVE: Measure the degree of compliance of prescriptions given to Chronic Obstructive Pulmonary Disorder (COPD) patients upon hospital discharge by comparing them to international recommendations. Identify factors that influence the degree of compliance. Evaluate the effect of that degree of compliance on the number of COPD exacerbations. METHOD: Retrospective observational study. We selected all episodes identified as COPD in a tertiary hospital during 2006. By consulting the clinical history database, we accessed the hospital discharge report and calculated the treatment's degree of proximity to the recommendations issued in the Global Initiative for Chronic Obstructive Lung Disease (GOLD). For each episode, we calculated the number of exacerbations in the six following months. Descriptive, bivariate statistical analysis. RESULTS: We obtained 365 episodes. The mean degree of compliance was 82% (SD=15.9). The patient's age and the severity of the disease did not influence the degree of compliance. We observed an inverse correlation between the hospital stay and the degree of compliance (p=0.026). Discharge reports issued by the Pneumonology Department had a significantly higher degree of compliance (p<0.001). No statistically significant relationship was found between the degree of compliance and the number of exacerbations. CONCLUSIONS: The degree of compliance is high according to the GOLD recommendations. The Pneumology Department had the highest degree of compliance, and a higher degree of compliance was related to a shorter hospital stay. The treatment compliance had no effect on the number of exacerbations of the disease.

Randomized, double-blind, controlled trial, phase III, to evaluate the use of platelet-rich plasma versus hyaluronic acid in hip coxarthrosis. / Ensayo clínico fase III para evaluar la eficacia y seguridad del uso de plasma rico en plaquetas frente a ácido hialurónico en coxartrosis.

AIMS OF THE STUDY: To compare efficacy and safety of a home-made platelet-rich plasma (PRP) solution versus hyaluronic acid in patients with hip osteoarthritis not responding to conservative treatment and to correlate cellular composition of PRP to clinical outcomes. MATERIAL AND METHODS: This is a phase III clinical trial, double-blinded, controlled and randomised into two treatment groups (PRP and hyaluronic acid). Patients received one hip ultrasound-guided injection. Follow up was 12 months. Pain was assessed using VAS score, HHS and WOMAC were used as functional scores, analgesia, adverse events, cellular components (PRP group) in peripheral blood and in PRP were recorded. Clinical response was assessed using OARSI criteria. RESULTS: Seventy-four patients were included. Both groups improved in VAS, WOMAC and HHS score and reduced the amount of analgesia (p<.05). Significant differences were seen at 1 year post-treatment in HHS score (PRP 70.9 [3.7-58], hyaluronic acid 60.2[43-74.2] p<.05). No adverse events were observed in none of the groups. Platelet concentration was different between responders and non-responders (at 1 month, non-responders 449[438-578] x103 platelets/µl versus responders 565 [481-666] x103 platelets/µl, p<.044). There was a correlation between leukocytes concentration and clinical scores (VAS at six months, r=0.748, p<.013, WOMAC at 6 months r=0.748, p <.013). Patients with early stage hip OA showed higher response rate to PRP compared with late stage (11.51 OR, 95%CI 2.34-50.65, p<.03). CONCLUSIONS: Platelet-rich plasma injection improved hip function, reduced pain and the use of analgesia. It is important to bear in mind the cellular composition in order to achieve a better clinical response.

[Study of rituximab efficacy, cost, safety, and compliance of its package leaflet in a tertiary hospital]. / Estudio de adecuación a la ficha técnica, efectividad, seguridad y coste del rituximab en un hospital de tercer nivel.

INTRODUCTION: The appearance of monoclonal antibodies, and specifically, rituximab, has provided a new approach to treating non-Hodgkin's lymphomas and rheumatoid arthritis. The purpose of this study is to analyse whether this drug is used according to its package leaflet in clinical practice, evaluate the treatment's efficacy and determine its cost. METHODS: Ambispective, observational single-centre study of medication use set up as a prescription evaluation for the indication of rituximab in a tertiary hospital between March 2003 and 31 December 2007. RESULTS: 82 of the 221 patients who were treated (37.1 %) received the drug for a condition that does not appear in the package leaflet. 51.1 % and 27.5 % of response and progression were registered for approved diagnoses and 34.9 % and 47 % for non-approved diagnoses; the death rate was 25.3 % and 41.5 % respectively. The mean cost per treatment episode was the highest for idiopathic thrombocytopenic purpura (11,683 euro), whilst the highest treatment cost per patient was associated with follicular lymphoma (15,940 euro). DISCUSSION: We found that the main cause of the high rate of non-compliance with the package leaflet is patient lack of response to standard treatments, together with clinical practice guides that support the use of rituximab for conditions other than those for which it is indicated. Nevertheless, most of the clinical trials evaluating the efficacy of rituximab for these unauthorized diagnostic profiles have poor methodology, are in phase II, are open studies, have low patient numbers, or in some cases, are not comparative.

[Analysis of prescriptions given on discharge from the emergencies department. Economic impact]. / Análisis de la prescripción al alta en urgencias. Impacto económico.

OBJECTIVE: To analyse the characteristics and cost of medical prescriptions given upon discharge from the casualty department, as well as the savings made by making substitutions with generic drugs or other equivalent pharmaceutical products in a third level hospital. METHODS: 669 patients were chosen using a cluster sample with a sub-sample. The following variables were considered: a) analysis of the prescription (medication quantification, active ingredients and most prescribed therapeutic groups, and possibility of prescribing generic drugs); b) calculation of cost and saving estimate (price to public and equivalent products); c) prescription quality (adherence to the guide and percentage of products of high therapeutic use.) RESULTS: 370 of the 669 patients received medication when they were discharged, with an average of 1.7 per patient. 629 products were prescribed, 16 % due to their active ingredient, with 37.53 % generic products available. The main active ingredients prescribed were paracetamol, ibuprofen and omeprazole amounting to 26.70 % of the total prescribed and the therapeutic groups that were highlighted were locomotor apparatus, the nervous system, the digestive apparatus and metabolism with 69.39 % of the total. 92.84 % of the prescriptions adhered to the pharmaco-therapeutic guide and 98.41 % were of high therapeutic use. The annual cost of prescribed medication was 1,013,778 Euro and the saving made by generic product substitution and a programme of therapeutic equivalents was 145,971 Euro. CONCLUSIONS: A prescription based on its active ingredients and a therapeutic and generic substitution produce a significant saving both for the patient and for the hospital.

[Drug-related problems in the emergency department observation area of a third-level hospital]. / Problemas relacionados con los medicamentos en el área de observación de urgencias de un hospital de tercer nivel.

OBJECTIVE: The therapeutic armamentarium of developed countries has experienced a great advance; however, increased drug therapy not only provides benefits, as the inappropriate use of drugs results in relevant consequences for patients. METHOD: A 3-month, descriptive, cross-sectional, randomized study in 125 patients seen at the emergency department observation area of a third-level hospital to identify drug-related problems (DRPs). A hospital adaptation of Dader s method was used. RESULTS: A mean of 0.94 DRPs per patient was obtained. Major DRPs (mDRPs) represented 50% of all DRPs; 69.50% of DRPs were avoidable; 44% were moderate, 38% mild, and 18% serious; 54.4% of patients were admitted to hospital, which originated in a mDRP in 25% of cases--this represents 50% of all patients with a mDRP. CONCLUSIONS: A significant portion of patients admitted to the observation area present there as a result of a DRP.

[Pharmaceutical care for patients with enteral nutrition]. / Original breve Atención farmacéutica en pacientes con nutrición enteral.

OBJECTIVE: To detect potential complications and interactions between drugs and enteral nutrition (EN) as to describe the interventions carried out by the pharmacist in those circumstances and to propose strategies of improvement. METHOD: Prospective assessment of patients admitted to hospital candidates to receive EN. The pharmacist worked as part of the team of Endocrinology and Nutrition for one month. A data collection form was designed for the study in which the following information had to be recorded: NE indications, nutrition characteristics (type, route of administration, infusion rate), pharmacological therapy, drug/EN interaction and complications. RESULTS: The study included 14 patients (mean age of 50 +/- 13 years) in which digestive (35.7%) and neurological (28.6%) complications were the most frequent indications for EN. Eleven patients (78.57%) reported complications associated to EN, mostly digestive (57.14%). The main cause for consultation was related to the administration of drugs via NGT (nasogastric tube). A total of 77 drugs were prescribed, 23 of which were administered in this way, so a guidelines for the administration of drugs via nasogastric tube was prepared. CONCLUSIONS: The hospital pharmacist can actively cooperate with nutritional support units, given the need to assess the nutritional support administered and to manage potential complications and interactions between nutritional status, drugs and artificial nutrition. The pharmacist also plays a significant role in the prevention and identification of problems related to the administration of drugs via NGT.

[Pharmacotherapy follow-up for patients admitted to the Internal Medicine Department of Hospital Infanta Margarita]. / Seguimiento farmacoterapéutico en pacients ingresados en el Servicio de Medicina Interna del Hospital Infanta Margarita.

INTRODUCTION: In pharmacotherapeutic follow-up a pharmacist is responsible for drug-related patient needs (DRPN) by detecting, preventing and solving medication-related problems aiming at specific results to improve patient quality of life. Drug-related problems are pharmacotherapy failures leading to failed therapeutic goals or undesirable events. MATERIAL AND METHODS: In this study, Daders methodology for pharmacotherapeutic follow-up was used in patients admitted to the Internal Medicine Department of Hospital Infanta Margarita, Cabra-Córdoba, Spain. RESULTS: In all, 85 DRPNs (2.7 DRPNs per patient) were identified, and 36 pharmaceutical procedures were performed, with physicians accepting 92% of said procedures. Forty-nine percent of drug-related problems were related to need, 40% to effectiveness, and 11% to safety. CONCLUSIONS: The presence of a pharmacist at the Internal Medicine Department allows the detection of DRPNs that are mostly related to need and effectiveness. Pharmaceutical procedures are widely accepted by medical teams.

[Drug therapy follow-up in patients admitted to a Surgery Department]. / Seguimiento del tratamiento farmacológico en pacientes ingresados en un Servicio de Cirugía.

INTRODUCTION: Patients admitted to surgery departments receive multiple drugs before, during and after surgical procedures. Anti-infectious therapy, anesthetics, anti-embolic agents, and analgesics stand out amongst others. Our objective was to implement pharmacotherapeutic follow-up as a means to detect, prevent, and solve medication-related problems (MRPs) in inpatients, and to establish consensus strategies to solve avoidable MRPs. MATERIAL AND METHODS: An observational prospective study of 22 patients hospitalized in a Surgery Department, Hospital Infanta Margarita, Cabra (Córdoba) was conducted. Dader methodology was adapted for drug therapy follow-up in the hospital setting. RESULTS: In all, 108 MRPs were detected; 22.04% were associated with medication needs (MRP1:13.6% and MRP2: 8.5%), 40.68% with ineffectiveness (MRP3: 22.0% and MRP4: 18.6%), and 37.28% with lack of safety (MRP5: 10.2% and MRP6: 27.1%). Out of 108 MRPs found, 64 (59.3%) were avoidable; 97 pharmaceutical interventions were carried out (89.8% of cases), acting in 63 (58%) MRPs detected in cooperation with physicians, while 46 MRPs were solved (42%). We found 1 MRP in each 2.6 patients -- admission days, and 1 MRP per 4.5 patients -- admission days occurred after pharmaceutical intervention during the study period. CONCLUSIONS: The use of pharmacotherapeutic follow-up in patients admitted to this department has improved the quality of health care.

Pharmacogenetics role in the safety of acenocoumarol therapy.

Vitamin K antagonists (VKAs) remain as the most prescribed drug for treatment and prevention of thrombotic disorders in many countries, despite the recent approval of the new oral anticoagulants (NOACs). Although effectiveness and safety of VKAs are tightly associated to maintaining the patient within the international normalised ratio (INR) therapeutic range (TWR), they have been likened to NOACs when patients are in good INR control (≥66% of TWR). Therefore, assessing the safety of patients should be a priority in the selection of the anticoagulation therapy. The aim of this study was to evaluate the association between CYP2C9*2, CYP2C9*3, VKORC1, CYP4F2*3, ABCB1 C3435T, APOE, CYP2C19*2 and CYP2C19*17 gene polymorphisms and treatment safety in 128 patients diagnosed with atrial fibrillation or venous thromboembolism during the initial first seven months of acenocoumarol therapy. After the first month, VKORC1-T-allele and APOE-E3/E3 genotype were independently associated to higher time above therapeutic range (TAR) and lower time below the therapeutic range (TBR). After seven months, VKORC1 T-allele predicted higher TAR, and was also associated to increased INR>4, particularly the TT-genotype (odds ratio [OR]: 32; 95% confidence interval [CI95%]: 6-175; p=810⁻5). C-alleles for CYP2C9*3 (OR: 5.5; CI95%: 1.8-17; p=0.003) and ABCB1 (OR: 8.9;CI95%: 1.1-70; p=0.039) independently influenced on INR>6 . Patients VKORC1-TT/ABCB1-C remained 26.8% [19.7-38.9] TAR, with associated relative risk (RR) for INR>4 1.8 higher (CI95%: 1.2-2.5; p=0.015). Patients VKORC1-TT also presented the highest risk of bleeding events (RR: 3.5;CI95%: 1.4-8.4; p=0,010). In conclusion, VKORC1, CYP2C9*3, APOE and ABCB1 genotypes should be considered in prevention of overanticoagulation and bleeding events in the initiation of acenocoumarol therapy.

[Boceprevir and telaprevir safety in routine clinical practice]. / Seguridad de boceprevir y telaprevir en la práctica clínica habitual.

PURPOSE: To compare the safety profile of telaprevir (TLV) and boceprevir (BOC) with each other and with those described in clinical trials (CT). MATERIAL AND METHODS: Retrospective multicenter observational study. Variables collected: age, sex, type of patient (naive, nonresponder or recurrent), fibroscan, Hb nadir, neutrophil and platelet count, presence of rash, anorectal discomfort, number of patients treated with erythropoiesis stimulating factors (EPO) and colony stimulating factors granulocyte (G-CSF). RESULTS: BOC vs CT: anemia (56.5% vs. 49%.), Thrombocytopenia (56.5% vs 32%, p = 0.023). neutropenia (17.4% vs. 29.5%). Use of EPO (13% vs 43%;. p = 0.008), pruritus (13% vs. 21.1%), rash (16.1% vs. 8.7%), anorectal discomfort (4.3% vs. 0%, p = 0.0001), dysgeusia (47.8% vs. 37%). TLV vs. CT: anemia (51.2% vs. 32%, p = 0.014), neutropenia (2.3 vs 3.6%), thrombocytopenia (41.9% vs. 27.4%, p = 0.05), pruritus (39.5% vs 47), rash (16.3% vs 55%, P <0.001), anorectal discomfort (39.5% vs 26%), dysgeusia (14% vs. 9.5%). BOC vs TLV: anemia (56.5% vs 51.2%), neutropenia (17.4% vs 2.3%), thrombocytopenia (56.5% vs 41.9%), rash (8.7% vs 16.3%), pruritus (39.5% vs 13%) and anorectal discomfort (4.3% vs 39.5%, P = 0.006), dysgeusia (14% vs 47.8%, P = 0.007), EPO (13% vs. 25.6%). GCSF was used for a patient treated with TLV. CONCLUSIONS: 1. BOC and TLV have shown a worse safety profile for anemia, thrombocytopenia and anorectal discomfort than those described in CT. 2. As in CT, anemia, neutropenia and thrombocytopenia were more common with BOC. Patients treated with TLV experienced more pruritus, rash and anorectal discomfort.

[Improvement of the knowledge on allergic cross-reactions between two drug groups: beta-lactams and NSAIDS]. / Mejora del conocimiento sobre reacciones alérgicas cruzadas en dos grupos de medicamentos: ß-lactámicos y AINEs.

OBJECTIVES: To identify opportunities for improving the available knowledge of health care professionals (particularly, physicians, pharmacists, and nurses) on crossed allergic reactions (CAR) to penicillins and NSAIDs. METHOD: Quasi-experimental prospective pre-exposure study at a 412-beds hospital. An assessment of the knowledge on CAR to penicillins and NSAIDs was performed by means of anonymous questionnaires before (1st questionnaire) and after (2d questionnaire) the implementation of a series of improvement measures: protocol of "patient allergic to drugs", pocket card, poster with summarized information, and informative talks. The questionnaires served as the CRF and the statistical analysis was done with the SPSS v18.0 software. RESULTS: The mean number of errors in the first questionnaire on CARs of penicillin allergic patient and on CARs of NSAIDs allergic patients was 20.53 and 27.62, respectively. The mean number of errors in the second questionnaire on CARs of penicillin allergic patient and on CARs of NSAIDs allergic patients was 2.27 and 7.26, respectively. All the results were significant for a p level < 0.005. CONCLUSIONS: - There is insufficient knowledge on CARs to penicillins and NSAIDS, which justifies improvement measures. - After the implementation of improvement measures, there is an increased knowledge on CARs to penicillins and NSAIDs in the study groups.

Objetivos: Identificar oportunidades de mejora, sobre el conocimiento disponible del personal sanitario (en concreto a personal médico, farmacéutico y de enfermería), sobre reacciones alérgicas cruzadas (RAC) de penicilinas y AINEs. Método: Estudio prospectivo cuasiexperimental pre-exposición en un hospital de 412 camas. Se realizó una valoración del conocimiento sobre RAC de penicilinas y AINEs, a través de encuestas anónimas, antes (1a encuesta) y después (2a encuesta) de la implantación de una serie de medidas de mejora: protocolo "paciente alérgico a medicamentos", tarjeta de bolsillo, póster resumen de información y charlas divulgativas. Las propias encuestas sirvieron de hoja de recogida de datos y el análisis estadístico se llevó a cabo con el programa SPSS v18.0. Resultados: La media de errores en las 1as encuestas sobre "RAC en paciente alérgico a penicilinas" y sobre "RAC en paciente alérgico a AINEs", fue de 20,53 y 27,62, respectivamente. La media de errores en las 2as encuestas sobre "RAC en paciente alérgico a penicilinas" y sobre "RAC en paciente alérgico a AINEs", fue de 2,27 y 7,26, respectivamente. Todos los resultados se consideraron significativos para un nivel 945;< 0,05. Conclusiones: - No se dispone de un nivel adecuado de conocimiento sobre RAC de penicilinas y AINEs, lo que justifica la realización de un ciclo de mejora. - Tras la implantación de las medidas de mejora se aprecia un aumento en el nivel de conocimiento sobre RAC en penicilinas y AINEs, en los grupos de estudio.

[Effect of pharmaceutical follow-up in patients with secondary hyperparathyroidism treated with cinacalcet]. / Efecto del seguimiento farmacoterapéutico en pacientes con hiperparatiroidismo secundario tratados con cinacalcet.

OBJECTIVES: To assess the effect of pharmaceutical intervention in the identification of drug-related problems, to improve desired clinical outcomes, and to evaluate the effectiveness of cinacalcet in achieving clinical outcomes recommended by the KDOQI Clinical Guidelines. METHOD: Quasi-experimental pre-post intervention study. Patients with Secondary Hyperparathyroidism due to Chronic Kidney Disease, aged ≥18 years and under treatment with cinacalcet were recruited at the hospital outpatient pharmacy between 2007 and 2009. Dáder follow-up method and SMAQ and Moriski questionnaires were used to verify adherence at the first interview. Then, the pharmacist analyzed each case and designed an adequate intervention. Clinical parameters were consulted in the hospital laboratory data base. RESULTS: Thirty four patients were included, 29 drug-related problems were found before pharmacist intervention, and among these, non-adherence was the most common (15). After the intervention, 9 drug-related problems remained, which means that 68.9% of them were resolved (P<0.001), reaching an adherence of 80%. Parathyroid hormone, calcium and calcium-phosphorus product serum levels decreased significantly after 3 months of treatment (P<0.001, <0.001 and 0.045, respectively), achieving the KDOQI Clinical Guideline recommendations. CONCLUSION: These results suggest that this simple and easy-to-apply intervention was effective in preventing and resolving drug-related problems in these patients. Moreover, it improved patient adherence and confirmed that cinacalcet treatment is effective for achieving the clinical outcomes recommended by KDOQI clinical guidelines.
