Reações adversas medicamentosas em pacientes em quimioterapia e estratégias de intervenções / Adverse drug reactions in chemotherapy patients and intervention strategies / Reacciones adversas a medicamentos en pacientes quimioterápicos y estrategias de intervención

A quimioterapia do câncer pode ocasionar reações adversas medicamentosas (RAM), podendo resultar de interações medicamentosas (IM) e impactar na adesão. O presente estudo relatou as RAM apresentadas por pacientes em quimioterapia (QT) e propôs estratégias de intervenções. Este trabalho foi aprovado em comité de ética (5.160.503), sendo incluídos 23 pacientes em quimioterapia (oral- VO e/ou endovenosa- EV) e todos foram entrevistados. Recebiam apenas o QTEV, 20 pacientes e 2 QTEV e VO, a maioria em tratamento paliativo (50%), predomínio de estadiamento IV, sendo as doenças mais presentes de pâncreas (27,3%), estômago (22,7%) e mama (18,2%) e esquema mais usado foi Carboplatina + Paclitaxel. As principais comorbidades foram diabetes e hipertensão arterial. As interações medicamentosas foram classificadas em graves (45%), moderadas (55%) e intencional (75%), sendo necessário introdução de medicamentos de suporte (61%). Houve RAM de maior gravidade, neutropenia, sendo necessário a suspensão temporária, e de menor gravidade náuseas. Houve um óbito relacionado a evolução de doença e, talvez, o tratamento possa ter contribuído. Ao final, foram feitas as intervenções para cada caso e validado o formulário para a consulta farmacêutica a pacientes oncológicos.

Cancer chemotherapy can cause adverse drug reactions (ADRs), which can result from drug interactions (IM) and impact adherence. The present study reported the ADRs presented by patients undergoing chemotherapy (CT) and proposed intervention strategies. This work was approved by the ethics committee (5,160,503), and 23 patients on chemotherapy (oral-VO and/or intravenous-IV) were included and all were interviewed. Only received CTIV, 20 patients and 2 CTIV and VO, most in palliative treatment (50%), predominance of stage IV, being the most common diseases of pancreas (27.3%), stomach (22.7%) and breast (18.2%) and the most used regimen was Carboplatin + Paclitaxel. The main comorbidities were diabetes and arterial hypertension. Drug interactions were classified as severe (45%), moderate (55%) and intentional (75%), requiring the introduction of supportive drugs (61%). There were more severe ADRs, neutropenia, requiring temporary suspension, and less severe nausea. There was one death related to the evolution of the disease and, perhaps, the treatment may have contributed. At the end, interventions were made for each case and the form for the pharmaceutical consultation to cancer patients was validated.

Las principales comorbilidades fueron la diabetes y la hipertensión arterial. Las interacciones farmacológicas se clasificaron como graves (45%), moderadas (55%) e intencionadas (75%), requiriendo la introducción de fármacos de apoyo (61%). La RAM más grave fue la neutropenia, que requirió la suspensión temporal, y la menos grave las náuseas. Hubo una muerte relacionada con la evolución de la enfermedad y, tal vez, el tratamiento pudo haber contribuido. Al final, se realizaron intervenciones para cada caso y se validó el formulario de consulta farmacéutica a pacientes oncológicos.

Adverse effects associated with favipiravir in patients with COVID-19 pneumonia: a retrospective study

ABSTRACT BACKGROUND: Favipiravir is generally used in treating coronavirus disease 2019 (COVID-19) pneumonia in Turkey. OBJECTIVE: To determine the side effects of favipiravir and whether it is a good treatment option. DESIGN AND SETTING: Retrospective study conducted in Atatürk Chest Diseases and Chest Surgery Training and Research Hospital, Ankara, Turkey. METHODS: 357 patients who completed favipiravir treatment at the recommended dose were included. 37 patients with drug side effects and 320 patients without drug side effects were examined in two groups. RESULTS: Side effects were observed in 37 (10.36%) out of 357 patients using favipiravir. The most common side effect was liver dysfunction, in 26 (7.28%) of the patients. The following other side effects were also observed: diarrhea (1.4%), nausea (0.84%), abdominal pain (0.28%) and thrombocytopenia (0.28%). One patient (0.28%) presented both increased transaminases and nausea. CONCLUSION: In this study, it was determined that favipiravir may constitute an alternative for treating COVID-19 pneumonia given that its side effects are generally well tolerated and not serious.

A prospective randomized controlled study on the effects of compound analgesia in ultra-pulsed fractional carbon dioxide laser treatment of post-burn hypertrophic scars in children / 中华烧伤杂志

Objective: To investigate the effects of compound analgesia on ultra-pulsed fractional carbon dioxide laser (UFCL) treatment of post-burn hypertrophic s in children. Methods: A prospective randomized controlled study was conducted. From April 2018 to March 2020, 169 pediatric patients with post-burn hypertrophic s admitted to the First Affiliated Hospital of Air Force Medical University were randomly divided into general anesthesia alone group (39 cases, 19 males and 20 females, aged 35 (21, 48) months), general anesthesia+lidocaine group (41 cases, 23 males and 18 females, aged 42 (22, 68) months), general anesthesia+ibuprofen suppository group (41 cases, 25 males and 16 females, aged 38 (26, 52) months), and three-drug combination group with general anesthesia + lidocaine+ibuprofen suppository (48 cases, 25 males and 23 females, aged 42 (25, 60) months), and the pediatric patients in each group were treated with corresponding analgesic regimens when UFCL was used to treat s, and the pediatric patients were given comprehensive care throughout the treatment process. The pain degree of pediatric patients scar was evaluated by facial expression,legs,activity,cry,and consolability (FLACC) of children's pain behavior scale at 0 (immediately), 1, 2, and 4 h after awakening from the first anesthesia, respectively. At 4 h after awakening from the first anesthesia of postoperative pain assessment, the self-made analgesia satisfaction questionnaire was used to evaluate the satisfaction for the analgesic effect of the pediatric patients or their families, and the satisfaction rate was calculated. Within 2 h after the first operation, the occurrences of adverse reactions of the pediatric patients, such as nausea and vomiting, headache, dizziness, drowsiness, etc, were observed and recorded. Before the first treatment and 1 month after the last treatment, the Vancouver scar scale (VSS) was used to evaluate the pediatric patients scar, and the difference value between the two was calculated. Data were statistically analyzed with least significant difference test, Kruskal-Wallis H test, chi-square test and Fisher's exact probability test. Results: At 0 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group (P<0.01). The FLACC scores of the pediatric patients in anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than that in general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 1 and 2 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were both significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 4 h after awakening from the first anesthesia, the FLACC scores of the pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01). At 4 h after awakening from the first anesthesia, the satisfactions rate with the analgesic effect in the four groups of pediatric patients or their families were 79.49% (31/39), 85.37% (35/41), 87.80% (36/41), and 97.92% (47/48), respectively. The satisfaction rate of the pediatric patients in three-drug combination group was significantly higher than those in general anesthesia alone group, general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group. Within 2 h after the first operation, there was no significant difference in the overall comparison of adverse reactions such as nausea and vomiting, headache, dizziness, and drowsiness of pediatric patients among the 4 groups (P>0.05). The VSS scores of pediatric patients before the first treatment, 1 month after the last treatment, and and the difference value between the two in the 4 groups were not significantly different (P>0.05). Conclusions: Three-drug combination for analgesia has a good effect in the treatment of hypertrophic scars after burn in pediatric patients with UFCL. Pediatric patients or their families are highly satisfied with the effect, and the treatment effect and incidence of adverse reactions are similar to other analgesic regimens, so it is recommended to be promoted in clinical practice.

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases / 北京大学学报(医学版)

Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases SUMMARY Programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) have been widely used in lung cancer treatment, but their immune-related adverse events (irAEs) require intensive attention. Pituitary irAEs, including hypophysitis and hypopituitarism, are commonly induced by cytotoxic T lymphocyte antigen 4 inhibitors, but rarely by PD-1/PD-L1 inhibitors. Isolated adrenocorticotropic hormone(ACTH) deficiency (IAD) is a special subtype of pituitary irAEs, without any other pituitary hormone dysfunction, and with no enlargement of pituitary gland, either. Here, we described three patients with advanced lung cancer who developed IAD and other irAEs, after PD-1 inhibitor treatment. Case 1 was a 68-year-old male diagnosed with metastatic lung adenocarcinoma with high expression of PD-L1. He was treated with pembrolizumab monotherapy, and developed immune-related hepatitis, which was cured by high-dose methylprednisolone [0.5-1.0 mg/(kg·d)]. Eleven months later, the patient was diagnosed with primary gastric adenocarcinoma, and was treated with apatinib, in addition to pembrolizumab. After 17 doses of pembrolizumab, he developed severe nausea and asthenia, when methylprednisolone had been stopped for 10 months. His blood tests showed severe hyponatremia (121 mmol/L, reference 137-147 mmol/L, the same below), low levels of 8:00 a.m. cortisol (< 1 μg/dL, reference 5-25 μg/dL, the same below) and ACTH (2.2 ng/L, reference 7.2-63.3 ng/L, the same below), and normal thyroid function, sex hormone and prolactin. Meanwhile, both his lung cancer and gastric cancer remained under good control. Case 2 was a 66-year-old male with metastatic lung adenocarcinoma, who was treated with a new PD-1 inhibitor, HX008, combined with chemotherapy (clinical trial number: CTR20202387). After 5 months of treatment (7 doses in total), his cancer exhibited partial response, but his nausea and vomiting suddenly exacerbated, with mild dyspnea and weakness in his lower limbs. His blood tests showed mild hyponatremia (135 mmol/L), low levels of 8:00 a.m. cortisol (4.3 μg/dL) and ACTH (1.5 ng/L), and normal thyroid function. His thoracic computed tomography revealed moderate immune-related pneumonitis simultaneously. Case 3 was a 63-year-old male with locally advanced squamous cell carcinoma. He was treated with first-line sintilimab combined with chemotherapy, which resulted in partial response, with mild immune-related rash. His cancer progressed after 5 cycles of treatment, and sintilimab was discontinued. Six months later, he developed asymptomatic hypoadrenocorticism, with low level of cortisol (1.5 μg/dL) at 8:00 a.m. and unresponsive ACTH (8.0 ng/L). After being rechallenged with another PD-1 inhibitor, teslelizumab, combined with chemotherapy, he had pulmonary infection, persistent low-grade fever, moderate asthenia, and severe hyponatremia (116 mmol/L). Meanwhile, his blood levels of 8:00 a.m. cortisol and ACTH were 3.1 μg/dL and 7.2 ng/L, respectively, with normal thyroid function, sex hormone and prolactin. All of the three patients had no headache or visual disturbance. Their pituitary magnetic resonance image showed no pituitary enlargement or stalk thickening, and no dynamic changes. They were all on hormone replacement therapy (HRT) with prednisone (2.5-5.0 mg/d), and resumed the PD-1 inhibitor treatment when symptoms relieved. In particular, Case 2 started with high-dose prednisone [1 mg/(kg·d)] because of simultaneous immune-related pneumonitis, and then tapered it to the HRT dose. His cortisol and ACTH levels returned to and stayed normal. However, the other two patients' hypopituitarism did not recover. In summary, these cases demonstrated that the pituitary irAEs induced by PD-1 inhibitors could present as IAD, with a large time span of onset, non-specific clinical presentation, and different recovery patterns. Clinicians should monitor patients' pituitary hormone regularly, during and at least 6 months after PD-1 inhibitor treatment, especially in patients with good oncological response to the treatment.

Câncer infantojuvenil: perfil dos pacientes atendidos na unidade de alta complexidade em oncologia (Unacon) em Rio Branco - Acre, Brasil, no ano de 2017 / Child and youth cancer: profile of patients seen at the oncology high complexity unit (Unacon) in Rio Branco - Acre, Brazil, in 2017

O câncer infanto-juvenil corresponde a um grupo de várias doenças que têm em comum a proliferação descontrolada de células anormais e que pode ocorrer em qualquer órgão em fase de desenvolvimento. Assim, o objetivo deste estudo foi descrever o perfil clínico e epidemiológico de crianças e adolescentes atendidos na UNACON durante o ano de 2017. Trata-se de um estudo descritivo, de corte transversal, desenvolvido a partir da análise de 20 prontuários de crianças e adolescentes com câncer. Foram coletados dados sobre as características sociodemográficas e clínicas-epidemiológicas dos pacientes. Os dados foram digitados, revisados e analisados no programa estatístico SPSS, na versão 21.0. Foram calculadas as frequências e a média das variáveis de interesse. Observou-se que a maioria dos pacientes tinha de um a três anos (45,0%), era do sexo masculino (60,0%), pardos (70,0%), com renda familiar de até um salário mínimo (60,0%) e metade procedia do interior do estado (50,0%), sendo o tipo de câncer mais diagnosticado a leucemia linfoide aguda (45,0%) e o principal tratamento utilizado a quimioterapia (95,0%), causando principalmente alopecia (100%), algia (100%), náuseas (65,0%), palidez (40,0%) e febre (25,0%) nos pacientes. Foi possível concluir que conhecer o perfil pode contribuir para a tomada de decisões da equipe gestora e profissionais de saúde da unidade no estabelecimento de medidas assistenciais aos pacientes, visando um atendimento mais humanizado, voltado para as necessidades sociodemográficas e levando em consideração as características clínicas-epidemiológicas desse grupo populacional.

Child and youth cancer corresponds to a group of several diseases that have in common the uncontrolled proliferation of abnormal cells and that can occur in any organ during the development phase. Thus, the purpose of this study was to describe the clinical and epidemiological profile of children and adolescents cared at UNACON during 2017. It is a descriptive, cross-sectional study developed from the analysis of 20 records of children and adolescents with cancer. Data on the sociodemographic and clinical-epidemiological characteristics of the patients were collected. The data were entered, reviewed and analyzed using the SPSS statistical program, version 21.0. The frequencies and the average of the variables of interest were calculated. It could be observed that the majority of patients were aged between one and three years (45.0%), male (60.0%), brown (70.0%), with a family income of up to one minimum wage (60.0%) and half (50.0%) came from the interior of the state, with acute lymphoid leukemia (45.0%) being the most frequent diagnosis, and chemotherapy (95.0%) the most frequent treatment used, causing mainly alopecia (100%), pain (100%), nausea (65.0%), pallor (40.0%) and fever (25.0%) in patients. It was possible to conclude that knowing the profile can contribute to the decision-making of the management team and health professionals at the health facility in the establishment of care measures for patients, aiming at a more humanized care, focused on sociodemographic needs and taking into account the clinical-epidemiological characteristics of this population group.

Risk factors associated with antineoplastic chemotherapy-induced nausea and vomiting / Fatores de risco associados a náuseas e vômitos induzidos por quimioterapia antineoplásica

ABSTRACT OBJECTIVE: To estimate the incidence and to evaluate risk factors for antineoplastic nausea and vomiting with high and moderate emetogenic chemotherapy in adult patients in the first treatment cycle. METHODS: Prospective cohort study with follow-up of 269 adults during the first cycle of antineoplastic chemotherapy. The incidence of nausea and vomiting was evaluated in the acute phase (0-24 hours), in the late phase (24 hours-5th day) and in the total phase (0-5th day). RESULTS: In total, 152 patients underwent high emetogenic chemotherapy and 117 moderate emetogenic chemotherapy. The relative frequency of nausea was higher when compared with vomiting in the acute phase (p < 0.001) and in the late phase (p < 0.001). The risk factors identified were: age group ≤ 49 years (odds ratio = 0.47; 95%CI 0.23-0.95) and 50-64 years (odds ratio = 0.45; 95%CI 0.23-0.87), tobacco use (odds ratio = 0.35; 95%CI 0.14-0.88), and high emetogenic chemotherapy (odds ratio 0.55; 95%CI 0.31-0.95). CONCLUSION: The incidence of nausea was higher than that of vomiting, and adverse effects were more frequent in the late phase. The results suggest the risk factors for chemotherapy-induced nausea and vomiting are tobacco, age (young adults), and high emetogenic chemotherapy.

RESUMO OBJETIVO: Estimar a incidência e avaliar os fatores de risco para náuseas e vômitos induzidos por antineoplásicos com alto e moderado potencial emético em pacientes adultos, no primeiro ciclo de tratamento. MÉTODOS: Estudo de coorte prospectiva, com 269 adultos acompanhados durante o primeiro ciclo de quimioterapia antineoplásica. A incidência de náuseas e vômitos foi avaliada na fase aguda (0-24 horas), na fase tardia (24 horas-5° dia) e na fase total (0-5° dia). RESULTADOS: 152 pacientes foram submetidos a quimioterápico com alto potencial emético e 117 a moderado potencial emético. A frequência relativa de náuseas foi maior quando comparada à de vômitos na fase aguda (p < 0,001) e na fase tardia (p < 0,001). Os fatores de risco identificados foram: faixa etária ≤ 49 anos (odds ratio = 0,47; IC95% 0,23-0,95) e 50-64 anos (odds ratio = 0,45; IC95% 0,23-0,87), uso de tabaco (odds ratio = 0,35; IC95% 0,14-0,88) e alto potencial emético dos quimioterápicos (odds ratio 0,55; IC95% 0,31-0,95). CONCLUSÃO: A incidência de náuseas foi maior do que a de vômitos, e na fase tardia os efeitos adversos foram mais frequentes. Os resultados sugerem que os fatores de risco para náuseas e vômitos induzidos por quimioterapia são o tabaco, a idade (adultos jovens) e o alto potencial emético do quimioterápico.

What do Cochrane systematic reviews say about the use of cannabinoids in clinical practice?

ABSTRACT BACKGROUND: The therapeutic effects of cannabinoid compounds have been the center of many investigations. This study provides a synthesis on all Cochrane systematic reviews (SRs) that assessed the use of cannabinoids as a therapeutic approach. DESIGN AND SETTING: Review of SRs, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina (EPM), Universidade Federal de São Paulo (UNIFESP). METHODS: A broad search was conducted in the Cochrane Database of Systematic Reviews to retrieve any Cochrane SRs that assessed the efficacy and safety of cannabinoids as a therapeutic approach. The results and key characteristics of all reviews included were summarized and discussed. RESULTS: Eight SRs were included. They assessed the use of cannabinoids for the following types of conditions: neurological (two SRs), psychiatric (two SRs), rheumatological (one SR), infectious (one SR) and oncological (two SRs). There was moderate-quality evidence showing that the use of cannabinoids reduced nausea and vomiting among adults, compared with placebo. Additionally, there was moderate-quality evidence showing that there was no difference between cannabinoids and prochlorperazine regarding the number of participants who reported vomiting, in this same population. CONCLUSIONS: This review identified eight Cochrane systematic reviews that provided evidence of unknown to moderate quality regarding the use of cannabinoids as a therapeutic intervention. Further studies are still imperative for solid conclusions to be reached regarding practical recommendations.

Orthodontic approach to treat complex hypodontia using miniscrews in a growing patient

This article reports orthodontic treatment of a case of hypodontia of five premolars in an 11-year-old female patient with a positive tooth size-arch length discrepancy in both dental arches. The patient had a straight profile with balanced facial growth. Setup manufacture revealed the possibility of achieving ideal occlusion by mesializing permanent molars up to 15 mm, in addition to keeping a primary molar in the dental arch. With the aid of absolute anchorage, the proposed mechanics was performed and the occlusion predicted in the setup was achieved, while profile and facial growth pattern were maintained. The use of miniscrews for extensive orthodontic movements was successful. Furthermore, one primary molar was extensively mesialized. The indication of gingivoplasty to correct gingival smile proved effective. This is considered a useful technique for orthodontists.

Este artigo apresenta o tratamento ortodôntico de um caso com hipodontia de cinco pré-molares, em uma paciente, de 11 anos de idade, com discrepância positiva de modelo em ambas as arcadas. A paciente apresentava perfil reto, com crescimento facial equilibrado. Por meio da confecção de set-up, verificou-se a possibilidade de se estabelecer uma oclusão ideal por meio da mesialização, de até 15mm, dos molares permanentes e manutenção de um molar decíduo no arco. Com o auxílio de ancoragem absoluta, foi realizada a mecânica proposta, alcançando-se a oclusão prevista em set-up, além da manutenção do perfil e do padrão de crescimento facial. A utilização de mini-implantes para grandes movimentos ortodônticos foi favorável, incluindo a extensa mesialização de um molar decíduo. A indicação da gengivoplastia para correção do sorriso gengival se mostrou acertada, sendo essa uma técnica de grande auxílio à Ortodontia.

O manejo da êmese em uma unidade oncológica: a necessidade da intervenção farmacêutica em tempo real / The Management of Emesis in an Oncology Unit: the Need for Pharmaceutical Intervention in Real Time

Introdução: Náuseas e vômitos estão entre os efeitos mais frequentes da quimioterapia antineoplásica, afetando cerca de 70% a 80% dos pacientes. A terapia antiemética objetiva prevenir o surgimento desses efeitos. Objetivo: Verificar a conformidade das prescrições de antieméticos, em uma unidade oncológica, de acordo com as diretrizes internacionais. Método: Estudo retrospectivo-descritivo a partir da coleta de dados das prescrições de quimioterapia do serviço de oncologia de um hospital universitário de Belém. Foram analisadas as prescrições dos pacientes ambulatoriais atendidos durante o período de um ano. Para a classificação do nível emetogênico de quimioterápicos isolados, utilizaram-se as classificações adotadas pela Multinational Association of Suportive Care in Cancer, American Society of Clinical Oncology e National Comprehensive Cancer Network; e, para associações de quimioterápicos, o algoritmo de Hesketh e colaboradores. Resultados: Entre as 143 prescrições analisadas, 27,3% apresentaram nível emetogênico baixo, 0,7% moderado e 72% alto. O estudo demonstrou que houve variabilidade entre as prescrições de antieméticos analisadas e as principais diretrizes. Quanto às não conformidades observadas, 53,8% ocorreram no manejo da terapia de nível emetogênico baixo, envolvendo associação ou dose; 100% no nível moderado e 27,2% no nível alto, relacionados à dose.Conclusão: A prevenção adequada das náuseas e vômitos é essencial para preservar a qualidade de vida dos pacientes oncológicos. Dessa forma, é necessário um protocolo intra-hospitalar para prescrição de antieméticos conforme as diretrizes internacionais. Esta pesquisa também alerta para a necessidade da intervenção farmacêutica em tempo real a fim de contribuir para o uso racional de medicamentos.

Incidence and management of chemotherapy-induced nausea and vomiting in women with breast cancer / Incidencia y gestión de náuseas y vómitos en tratamiento quimioterapico en mujeres con cáncer de mama / Ocorrência e manejo de náusea e vômito no tratamento quimioterápico em mulheres com câncer de mama

The objective of this study was to analyze the incidence of chemotherapy-induced nausea and vomiting in women with breast cancer and identify strategies used by them to control these signs and symptoms. Data for this cross-sectional study were collected through interviews during the last cycle of chemotherapy, between August 2011 and March 2012, in a university hospital in the State of São Paulo. The sample consisted of 22 women between the ages of 31 and 70, of whom 77.3% reported nausea and 50% vomiting during treatment. Regarding symptom management, 82% of the women reported having received some information centered on the use of prescribed medication. However, 27.3% did not know what medication they had taken. We concluded that there is a lack of systematic care and institutional protocol to guide professionals in providing standardized information to women so they can better control nausea and vomiting.

Este estudio objetivó analizar la incidencia de náuseas y vómitos en mujeres con cáncer de mama durante la quimioterapia, identificar el manejo utilizado para controlar estos signos y síntomas. Estudio transversal, cuyos datos fueron recolectados por medio de entrevistas en el último ciclo de quimioterapia entre agosto 2011 y marzo 2012 en un hospital universitario en el Estado de São Paulo. La muestra consistió de 22 mujeres, con edades entre 31 y 70 años, que el 77,3% reportó náuseas y el 50% vómitos durante el tratamiento. Cuanto al manejo, el 82% afirmó que habían recibido algún tipo de información centrada en el uso de la medicación prescrita, sin embargo, el 27,3% no supo responder cuál medicación fue utilizada. Se concluye que falta de sistematización de la atención y protocolo institucional para orientar profesionales para ofrecer información estandarizada, posibilitando el seguimiento de las mujeres para tener un mejor control de náuseas y vómitos.

Pesquisa transversal, cujos dados foram coletados por meio de entrevista, no último ciclo de quimioterapia, entre agosto de 2011 e março de 2012 em um hospital universitário no interior do Estado de São Paulo. A amostra foi composta por 22 mulheres, com idade entre 31 e 70 anos, e 77,3% relataram náusea e 50% vômito, durante o tratamento. Quanto ao manejo, 82% delas afirmaram ter recebido algum tipo de informação que ficou centrada no uso da medicamento prescrito, entretanto, 27,3% não souberam responder qual medicamento usaram. Concluiu-se que há falta de sistematização da assistência e protocolo institucional que norteiem os profissionais a fornecer informações padronizadas, possibilitando o seguimento das mulheres, a fim de terem controle mais adequado da náusea e vômito.

Carbamazepine for prevention of chemotherapy-induced nausea and vomiting: a pilot study / Carbamazepina para prevenção de náusea e vômito induzidos por quimioterapia: um estudo piloto

CONTEXT AND OBJECTIVE: Nausea and vomiting are major inconveniences for patients undergoing chemotherapy. Despite standard preventive treatment, chemotherapy-induced nausea and vomiting (CINV) still occurs in approximately 50% of these patients. In an attempt to optimize this treatment, we evaluated the possible effects of carbamazepine for prevention of CINV. DESIGN AND LOCATION: Prospective nonrandomized open-label phase II study carried out at a Brazilian public oncology service. METHODS: Patients allocated for their first cycle of highly emetogenic chemotherapy were continuously recruited. In addition to standard antiemetic protocol that was made available, they received carbamazepine orally, with staggered doses, from the third day before until the fifth day after chemotherapy. Considering the sparseness of evidence about the efficacy of anticonvulsants for CINV prevention, we used Simon's two-stage design, in which 43 patients should be included unless overall complete prevention was not achieved in 9 out of the first 15 entries. The Functional Living Index-Emesis questionnaire was used to measure the impact on quality of life. RESULTS: None of the ten patients (0%) presented overall complete prevention. In three cases, carbamazepine therapy was withdrawn because of somnolence and vomiting before chemotherapy. Seven were able to take the medication for the entire period and none were responsive, so the study was closed. There was no impact on the patients' quality of life. CONCLUSION: Carbamazepine was not effective for prevention of CINV and also had a deleterious side-effect profile in this population. .

CONTEXTO E OBJETIVO: Náusea e vômito são inconvenientes importantes para pacientes submetidos a quimioterapia. A despeito do tratamento preventivo padrão, náuseas e vômitos induzidos por quimioterapia (NVIQ) ocorrem em aproximadamente 50% dos pacientes. Na tentativa de otimizar este tratamento, avaliamos os possíveis efeitos da carbamazepina na prevenção de náuseas e vômitos induzidos por quimioterapia. TIPO DE ESTUDO E LOCAL: Estudo fase II, prospectivo, não randomizado, aberto, realizado em um serviço público brasileiro de oncologia. MÉTODOS: Recrutaram-se continuamente pacientes alocados para o primeiro ciclo de quimioterapia altamente emetogênica. Além do protocolo anti-emético padrão disponibilizado, os pacientes receberam carbamazepina, por via oral, em doses escalonadas, a partir do terceiro dia anterior até o quinto dia após a quimioterapia. Dada a escassa evidência de eficácia dos anticonvulsivantes na prevenção de NVIQ, adotamos o desenho de Simon em duas fases, que deveria incluir 43 pacientes a não ser que prevenção completa global não fosse alcançada em 9 dos primeiros 15 participantes. O questionário "Functional Living Index-Emesis" foi usado para avaliar o impacto na qualidade da vida. RESULTADOS: Nenhum dos 10 pacientes (0%) apresentou prevenção completa global. Três tiveram a carbamazepina suspensa por sonolência e vômito antes da quimioterapia. Sete foram capazes de tomar a medicação por todo o período proposto e nenhum obteve resposta, sendo então interrompido o estudo. Não houve impacto na qualidade da vida. CONCLUSÃO: Carbamazepina não foi efetiva para prevenção de NVIQ e apresentou perfil deletério de efeitos adversos nesta população. .

Toxicity Profile of Temozolomide in the Treatment of 300 Malignant Glioma Patients in Korea

This study evaluated the toxicity profiles of temozolomide in the treatment of malignant glioma as either concurrent or adjuvant chemotherapy. We retrospectively reviewed the medical records of 300 malignant glioma patients treated with temozolomide in two medical institutions in Korea between 2004 and 2010. Two hundred nine patients experienced a total of 618 toxicities during temozolomide therapy. A total of 84.8% of the 618 toxicities were Common Terminology Criteria for Adverse Events (CTCAE) grade 1 or 2, while 15.2% were grade 3 or 4. Among the hematologic toxicities, thrombocytopenia (13.7%), anemia (11.0%), and AST/ALT increases (7.0%) were common. Among the non-hematologic toxicities, nausea (44.3%), vomiting (37.0%), and anorexia (14.3%) were the three most common toxicities. There was no mortality due to temozolomide. Although temozolomide showed many types of toxicities, the majority of the toxicities were tolerable and of lower grade. Gastrointestinal troubles are the most common toxicities in Korean patients treated with temozolomide.

A Phase 3, randomized, double-blind study of single-dose fosaprepitant for prevention of cisplatin-induced nausea and vomiting: Results of an Indian population subanalysis.

Context: Currently, there is limited data on the prevention of chemotherapy-induced nausea and vomiting (CINV) in Indian patients. Aims: This post hoc study assessed the efficacy and safety of fosaprepitant compared with aprepitant for prevention of CINV in the Indian population. A subgroup analysis was performed from data collected in a phase 3 study of intravenous (IV) fosaprepitant or oral aprepitant, plus the 5-HT 3 antagonist ondansetron and the corticosteroid dexamethasone, in cisplatin-naοve patients with solid malignancies. Materials and Methods: Patients scheduled to receive cisplatin (≥70 mg/m 2 ) were administered a single IV dose of fosaprepitant dimeglumine (150 mg) on day 1 or a 3-day dosing regimen of oral aprepitant (day 1:125 mg, days 2 and 3:80 mg) with standard doses of ondansetron and dexamethasone. Patients recorded nausea and/or vomiting episodes and their use of rescue medication and were monitored for adverse events (AEs) and tolerability. Statistical Analysis Used: Differences in response rates between fosaprepitant and aprepitant were calculated using the Miettinen and Nurminen method. Results: In the Indian subpopulation (n = 372), efficacy was similar for patients in both the fosaprepitant or aprepitant groups; complete response in the overall, acute, and delayed phases and no vomiting in all phases were approximately 4 percentage points higher in the fosaprepitant group compared with the aprepitant group. Fosaprepitant was generally well-tolerated; common AEs were similar to oral aprepitant. Conclusions: IV fosaprepitant is as safe and effective as oral aprepitant in the Indian subpopulation and offers an alternative to the oral formulation.

Intervenções Não Farmacológicas para Náuseas e Vômitos Induzidos por Quimioterapia: revisão integrativa / Non Pharmacological Interventions for Chemotherapy Induced Nauseas and Vomits: integrative review

Nausea and vomiting are one of the most common gastrointestinal toxicities of antineoplastic treatment; it may affect negatively patient`s nutritional condition, hidroeletrolitic balance and quality of life. This study aimed to identify evidences in medical literature regarding non-pharmacologic interventions to prevent and treat chemotherapy induced nausea and vomiting. We performed an integrative review on online databases for that purpose. We elected 9 articles from this research, which presented the following possible non-pharmacological interventions for chemotherapy emesis: accupressure, acupuncture, electroacupuncture, relaxing techniques and yoga. The authors concluded that the results suggested that these interventions should be recommended for cancer patients, mainly those presenting chemotherapy emesis in consecutive cycles.

Náuseas e vômitos são os sinais e sintomas mais prevalentes em relação à toxicidade gastrintestinal decorrentes da quimioterapia antineoplásica, podendo afetar a condição nutricional, o equilíbrio hidroeletrolítico e a qualidade de vida do paciente. Esse estudo teve como objetivo identificar evidências na literatura científica relacionadas a intervenções não farmacológicas para náuseas e vômitos induzidos por quimioterapia. Foi realizada revisão integrativa da literatura. 09 estudos elegíveis apresentaram intervenções não farmacológicas para o manejo de náuseas e vômitos em pacientes submetidos à quimioterapia, a saber: acupressão, acupuntura, eletroacunpuntura, relaxamento e yoga. Os autores concluem que os resultados sugerem que o uso de intervenções não farmacológicas para náuseas e vômitos induzidos por quimioterapia deve ser considerado em pacientes com câncer principalmente naqueles que experimentam recorrência de êmese em ciclos subseqüentes.

Efficacy and safety of ginger to reduce nausea and vomiting of pregnancy: a systematic review and meta-analysis

To assess the efficacy and safety of ginger [rhizome of Zingiber officinale] to reduce severity of nausea and numbers of vomiting in early pregnancy. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL and SID databaseswere searched for relevant sources. Randomized trials of oral ginger in comparison with placebo for nausea and/or vomiting in early pregnancy were selected. Two reviewers assessed the trial quality and extracted the data independently. Five trials met the inclusion criteria to assess the efficacy. Based on these trials, there was a significant reduction in severity of nausea after taking ginger compared with placebo [Pooled SMD= 0.882, 90% confidence interval 0.267 to 1.496]. Also there was similar effect in reducing number of vomiting [Pooled SMD= 0.631, 90% confidence interval 0.433 to 0.829]. In addition, there were 5 trials or observational studies which had assessed the potential fetomaternal side effects of ginger. There was no supporting evidence for increasing pregnancy complications after using Ginger. Based on the current evidences, Ginger reduces the severity of nausea and frequency of vomiting in early pregnancy. There are considerations about adverse effects, but they are not supported by the clinical evidence. It seems that ginger could be used during pregnancy in therapeutic doses [almost 1 gr per day] for limited durations

Effect of acupressure by sea-bands on nausea and vomiting of pregnancy

To determine the effect of continuous acupressure at P6.applied by Sea-Bands with acupressure buttons on the frequency and severity of nausea and vomiting of pregnancy during the 8-20 weeks. A two-group quasi-experimental posttest-only and posttest-repeated measure in seventeen medical clinics or offices in southern Tehran was carried out. A convenience sample of Persian-speaking; healthily pregnant women in their 8-20 weeks of pregnancy; who had at least one episode of nausea, vomiting, or both before their prenatal clinic/ office visit where they were recruited. The women were randomly assigned to treatment or placebo groups. Treatment group [1] applied Sea-Bands with acupressure buttons to both wrists for 4 days and removed the Sea-Bands for 3 subsequent days. Placebo group [2] applied the Sea-Bands with out acupressure buttons to both wrists on the same time schedule as group 1. Self-reported daily diaries of the number of times per day that participants experienced nausea, the severity of nausea, the number of vomiting episodes per day, and the severity of vomiting were recorded. Mann-Whitney U test revealed that the treatment group had significantly less frequency and severity of nausea and vomiting of pregnancy while wearing the Sea-Bands than did the placebo group. The treatment group also had significantly less frequency and severity of nausea and vomiting of pregnancy while wearing the Sea-Bands than when not wearing the Sea-Bands. Sea-Bands with acupressure buttons are a noninvasive, inexpensive, safe, and effective treatment for the nausea and vomiting of pregnancy
