Incorporação de esomeprazol em um hospital universitário: uma análise de custo-minimização / Incorporation of esomeprazole in a university hospital: a cost-minimization analysis

Introdução: Inibidores de bomba de prótons (IBP) são amplamente utilizados na profilaxia de úlceras de estresse. O omeprazol é o IBP mais prescrito no Brasil, porém, sua formulação oral convencional é inadequada para administração por sonda devido ao risco de obstrução. A apresentação injetável de omeprazol possui custo muito superior à formulação oral. O esomeprazol, por ser constituído de microgrânulos, é uma alternativa ao omeprazol injetável, pois pode ser administrado por sonda e ainda possibilitaria redução de custos. Objetivo: Analisar por meio de custo-minimização o impacto financeiro da incorporação do esomeprazol em um hospital universitário secundário. Material e Métodos: Estudo observacional transversal retrospectivo para identificar e analisar o consumo e custo relacionado ao uso de omeprazol injetável e esomeprazol nos anos de 2021 e 2022. A partir dos dados levantados, foi realizada análise de custo-minimização e determinado o impacto financeiro após incorporação do esomeprazol. Resultados: Houve redução de 76,7% no consumo de omeprazol injetável no ano de 2022. A análise de custo-minimização apontou um custo real de R$20.374,96 no ano de 2022, referente às 906 doses utilizadas no período, destas, 46,4% eram de omeprazol injetável e 53,6% de esomperazol. Considerando o cenário com terapia exclusiva com omeprazol injetável, o custo simulado foi de R$ 41.252,05. O impacto financeiro foi de R$ -20.877,09, resultando em economia de recursos de 50,6%. Conclusão: A incorporação de esomeprazol no elenco de medicamentos de um hospital universitário gerou redução significativa de custo, implicando em economia de mais de 50% no consumo global de IBP e de mais de 70% no consumo de omeprazol injetável, no ano de 2022.

Introduction: Proton pump inhibitors (PPIs) are widely used in stress ulcers prophylaxis. Omeprazole is the most prescribed PPI in Brazil, but its conventional oral formulation is unsuitable for administration through a tube due to the risk of obstruction. The injectable presentation of omeprazole has a much higher cost than the oral formulation. Esomeprazole, composed of microgranules, is an alternative to injectable omeprazole as it can be administered through a tube and could potentially lead to a cost reduction. Objective: To analyze, through cost minimization, the financial impact of incorporating esomeprazole in a secondary university hospital. Material and Methods: A retrospective cross-sectional observational study was conducted to identify and analyze the consumption and cost related to the use of injectable omeprazole and esomeprazole in the years 2021 and 2022. Cost-minimization analysis was performed based on the collected data, to determine the financial impact after incorporating esomeprazole. Results: There was a 76.7% reduction in the consumption of injectable omeprazole in 2022. The cost-minimization analysis indicated a real cost of R$20,374.96 in 2022 for the 906 doses used during the period, of which 46.4% were injectable omeprazole and 53.6% were esomeprazole. Considering the scenario with exclusive therapy using injectable omeprazole, the simulated cost was R$41,252.05. The financial impact was R$-20,877.09, resulting in a resource saving of 50.6%. Conclusion: The incorporation of esomeprazole into the list of medications at a university hospital led to a significant cost reduction, resulting in over 50% savings in PPI consumption and over 70% in injectable omeprazole consumption, in 2022.

Efficacy of intratympanic injection versus intravenous drip of prednisolone acetate in the treatment of sudden hearing loss / 中国基层医药

Objective:To investigate the efficacy of intratympanic injection versus intravenous drip of prednisolone acetate in the treatment of sudden hearing loss. Methods:A total of 120 patients with sudden hearing loss who received treatment in the Department of Otolaryngology, Mingzhou Hospital between January 2017 and January 2020 were included in this study. They were divided into intratympanic injection group (intratympanic injection of prednisolone acetate, n = 60) and intravenous injection group (intravenous injection of prednisolone acetate, n = 60) according to route of drug administration. After 8 days of treatment, clinical efficacy was compared between the two groups. The hearing thresholds at 500 Hz and 1 000 Hz in both groups were detected using pure tone audiometry. The levels of procalcitonin and high-sensitivity C-reactive protein and adverse drug reactions were compared between the two groups. Results:After treatment, total response rate in the intratympanic injection group was significantly higher than that in the intravenous injection group (93.33% vs. 80.00%, χ2 = 4.61, P < 0.05). The hearing threshold at 500 Hz in the intratympanic injection group was significantly lower than that in the intravenous injection group [(38.69 ± 3.56) vs. (42.36 ± 4.36), t = 5.05, P < 0.001). The hearing threshold at 1 000 Hz in the intratympanic injection group was significantly lower than that in the intravenous injection group [(32.36 ± 3.36) vs. (40.15 ± 4.12), t = 11.35, P < 0.001). After treatment, procalcitonin level in the intratympanic injection group was significantly lower than that in the intravenous injection group [(0.65 ± 0.12) μg/L vs. (0.98 ± 0.15) μg/L, t = 13.30, P < 0.001)]. High-sensitivity C-reactive protein level in the intratympanic injection group was significantly lower than that in the intravenous injection group [(3.28 ± 0.36) mg/L vs. (5.26 ± 0.56) mg/L, t = 23.03, P < 0.001]. There was no significant difference in incidence of adverse reactions between intratympanic injection and intravenous injection groups (8.33% vs. 10.00%, χ2 = 0.10, P > 0.05). Conclusion:Compared with intravenous drip of prednisolone acetate, intratympanic injection of prednisolone acetate can improve the clinical symptoms of patients with sudden hearing loss and enhance clinical efficacy.

Fatores associados com a escolha da terapia nos pacientes com doença inflamatória intestinal no Brasil / Factors associated with patient´s preference in choosing their therapy for inflammatory bowel disease in brazil

BACKGROUND: Biological therapy and new drugs have revolutionized the treatment of inflammatory bowel disease. Ideally, the choice of medication should be a shared decision with the patient, aiming at greater satisfaction, compliance, and consequently, favorable clinical outcome. OBJECTIVE: This study aims to evaluate patient's preferences in the choice of their therapy and the factors that influence this choice. METHODS: This cross-sectional study enrolled 101 outpatients with Crohn's disease or ulcerative colitis. The inclusion criteria were age ≥18 years and no previous exposure to biological therapy. Patients' preferences were assessed through questions that addressed the preferred mode of administration (oral, subcutaneous, or intravenous) and the factors that determined the choice of medication (efficacy, medical indication, fear of medication, convenience, mode of application, and personal doctors' indication). RESULTS: The mean age was 43.6±13.5 years, 75.3% were female, and 81.2% were cases of ulcerative colitis. Regarding the mode of administration, the majority of patients preferred oral (87.1%), followed by intravenous (6.93%) and subcutaneous (5.94%) medications. The reasons were "I prefer to take it at home" (42.57%), "I have more freedom" (36.63%), "I don't like self-application" (29.70%), and "I believe it works better" (19.80%). Younger patients and patients in clinical disease activity preferred intravenous mode compared to the oral route (P<0.05). Doctor's opinion (98%) was an important factor associated with the medication choice. CONCLUSION: Oral route was the preferred mode of administration and most patients took their physician's opinion into account in their choice of medication.

They recognize the importance of communication and notification in this process for improving patient safety.

Tratamento da hipomelanose gutata idiopática com laser Er:YAG 2940nm isolado ou combinado ao drug delivery de piperina: um estudo-piloto comparativo / Treatment of idiopathic guttate hypomelanosis with Er:YAG 2940nm laser alone or combined to piperine drug delivery: a pilot and comparative study

Introdução: Introdução: A hipomelanose gutata idiopática constitui uma leucodermia adquirida, cujas opções terapêuticas disponíveis apresentam resultados inconsistentes. Objetivos: Avaliar o efeito do laser fracionado ablativo isolado ou combinado ao drug delivery de piperina para tratamento de hipomelanose gutata idiopática. Materiais e métodos: Em um estudo prospectivo e comparativo, sete pacientes apresentando HGI nas pernas foram selecionadas, sendo escolhidas cinco lesões em cada perna de cada uma. Ambas as pernas de cada paciente foram submetidas a duas sessões de laser Er:- YAG 2940nm, seguido de drug delivery de piperina 20% somente na perna direita. A avaliação foi feita por avaliadores cegos por meio de fotografias e medidas comparativas das lesões. Resultados: O tamanho das lesões variou de 0,2cm a 1,5cm. Ambos os tratamentos reduziram significativamente o tamanho das lesões (p<0,00008 perna direita e p<0,002 perna esquerda). O método de equações de estimativas generalizadas demonstrou que não houve diferença estatística entre os grupos em relação à redução do tamanho das lesões. A avaliação atingiu melhores escores para a perna direita (laser + piperina) (p=0,126). Conclusão: Embora diferenças estatisticamente significativas não tenham sido encontradas entre o lado tratado com laser e drug delivery versus o lado tratado somente com laser, acreditamos que a técnica possa representar uma opção no arsenal terapêutico.

Introduction: Idiopathic guttate hypomelanosis is an acquired leukoderma, whose available therapeutic options have inconsistent results. Objectives: To evaluate the effect of isolated or combined ablative fractionated laser to drug delivery of piperine for treatment of idiopathic guttate hypomelanosis. Materials and methods: In a prospective and comparative study, seven patients with idiopathic guttate hypomelanosis in the legs were elected, and five lesions were selected on each leg of each. Both legs of each patient were submitted to two Er:YAG 2940nm laser sessions, followed by drug delivery of piperine 20% only in the right leg. Blind evaluators conducted the assessment through photographs and comparative measurements of the lesions. Results: The lesion size ranged from 0.2cm to 1.5 cm. Both treatments significantly reduced lesion size (p< 0.00008, right leg; p< 0.002, left leg). The generalized estimating equation method showed that there was no statistical difference between the groups regarding the reduction of lesion size. The evaluation achieved better scores for the right leg (laser + piperine) (p=0.126). Conclusion: Although statistically significant differences were not found between the side treated with laser and drug delivery versus the side treated only with laser, we believe that the technique may represent an option in the therapeutic arsenal.

The Effects of Menopausal Hormone Therapy on Serum Level of C-reactive Protein in Postmenopausal Korean Women

OBJECTIVES: Inflammation is a major mechanism underlying coronary heart disease (CHD) and C-reactive protein (CRP) is a marker of inflammation. When administered soon after menopause, menopausal hormone therapy (MHT) prevents CHD. This study was conducted to examine the impact of estrogen by administration route on CRP in postmenopausal Korean women using micronized progesterone (MP4) for endometrial protection. METHODS: This retrospective cohort study included 129 healthy women without CHD risk factors. Eighty-nine women took oral estrogen (conjugated equine estrogen, 0.625 mg/day or equivalent), and 40 women applied a 1.5-mg/day 0.1% percutaneous estradiol gel. MP4 was added in 82 women with an intact uterus. The CRP level was measured at baseline and three and six months after initiation of MHT. RESULTS: The baseline characteristics were comparable between the MHT groups except current age and age at menopause. After controlling for age, menopausal age, body mass index, and basal CRP, no significant change in CRP was observed in the oral estrogen group (n = 29). Follow-up CRP levels were also similar to the baseline in the percutaneous estrogen group (n = 18). However, three-month CRP was significantly lower than six-month CRP, and there was a significant time trend within the percutaneous estrogen group. However, the group difference did not reach statistical significance. CRP also did not differ by addition of MP4 in either group. CONCLUSIONS: In postmenopausal Korean women, no change in CRP was observed with oral estrogen, while percutaneous estrogen might decrease CRP.

Pharmacokinetics and drug therapy in neonates

Neonates include both full term and preterm infants up to 28 days of age. The heterogeneity and rapid physiologic change of neonates affect all aspects of pharmacokinetics such as absorption, distribution, metabolism, and elimination. This feature should be considered in determining the dose and regimen of drug therapy in neonates. However, the research on the safety and efficacy of specific drugs is limited due to ethical and technical issues. This review article focuses on the neonatal pharmacokinetics and the rationales of drug therapy in neonates based on findings of previous studies and empirical evidence.

Duración del tratamiento y administración oral de antimicrobianos en neumonía adquirida en la comunidad / Duration of treatment and oral administrad on of antibiotics in community acquired pneumonia

Community acquired pneumonia (CAP) is an important cause of morbidity and mortality around the world, with high treatment costs due to hospitalization and complications (adverse events due to medications, antibiotic resistance, healthcare associated infections, etc.). It has been proposed administration of short courses and early switch of intravenous administration to oral therapy to avoid costs and complications. There are recommendations about these topics in national and intemational guidelines, based on clinical trials which do not demónstrate diffe-rences in mortality and complications when there is an early change from intravenous administration to the oral route. There are no statistically significant differences in safety and resolution of the disease when short and long treatment schemes were compared. In this review we present the most important guidelines and clinical studies, taking into account the pharmacological differences between different medications. It is considered that early switch from intravenous to oral administration route and use of short cycles in CAP is safe and brings benefits to patients and institutions.

La neumonía adquirida en la comunidad (NAC) es una causa importante de morbilidad y mortalidad en el mundo, con costos elevados por cuenta de las hospitalizaciones y las complicaciones (infección asociada al cuidado de la salud, efectos adversos de medicamentos, resistencia antimicrobiana, etc.). Ante este panorama se ha propuesto administrar ciclos cortos y el cambio temprano de la vía administración de antimicrobianos de endovenosa a oral. Existen recomendaciones acerca de los puntos anteriores en guías locales e internacionales, así como ensayos clínicos que no demuestran diferencias en cuanto a mortalidad y complicaciones cuando se realiza un cambio temprano de vía de administración de endovenosa a oral en NAC. Tampoco hay diferencias estadísticamente significativas en seguridad y resolución de enfermedad cuando se compararon esquemas cortos y prolongados. En esta revisión se presentan las guías y estudios más importantes, considerando las diferencias farmacológicas de los diferentes medicamentos. Se considera que el cambio temprano de vía de administración y el uso de ciclos cortos en NAC es seguro y presenta beneficios para pacientes e instituciones.

Objective To investigate the therapeutic effect of topical corticosteroids injection and systemic application in the treatment of sudden hearing loss.Methods Total of 58 patients with sudden hearing loss were ran-domly divided into two groups.The systemic application group:dexamethasone (DEX)was applied by intravenous injection in dose of 10mg ×3d,followed by 5mg ×4d.And the postauricular injection group:methylprednisolone sodium succinate of 40mg was injected into cortical bone of mastoid region every three days,until hearing back to normal,or 15 days.SPSS 13.0 software was used to analyze the data.Results The total effective rate of systemic application group was 67.7%,the total effective rate of postauricular injection group was 64.7%.There was no statistical differ-ence between the two groups (χ2 =2.58,P =0.316).The recovery rate in cases with postauricular injection group was significantly increased in comparison with the systemic application group,but no statistical difference between the two groups(t =2.71,P =0.062).Patients with hearing loss in low frequencies(250Hz,500Hz),the recovery rate in cases with postauricular injection group was significantly increased in comparison with the systemic application group (t =3.82,P =0.031;t =3.26,P =0.042).Conclusion Postauricular topical injection and systemic application of glucocorticoids in the treatment of sudden hearing loss are all have good curative effect.Systemic application is select-ed by conventional treatment,and topical injection has a better effect in the hearing loss of low -middle frequencies.

The homing of bone marrow mesenchymal stem cells transplanted via the trachea into rats exposed to silica dust / 中国组织工程研究

BACKGROUND:Bone marrow mesenchymal stem cels transplantationvia the trachea can relieve the lung injury of rats exposed to silica dust, but their distribution and migrationin vivois stil unclear. OBJECTIVE:To investigate the distribution and homing of bone marrow mesenchymal stem cels transplanted via the trachea into rats exposed to silica dust. METHODS: Bone marrow mesenchymal stem cels from Sprague-Dawley rats were isolated through bone marrow adherent method and transfected with lentivirus carrying enhanced green fluorescent protein gene (Lv-eGFP). Trypan blue staining and cel counting kit-8 were applied to assay the viability and proliferation of the transfected and untransfected cels. Sprague-Dawley rats, SPF level, were randomized into control group and silica dust exposure group. Rats in the two groups were respectively injectedvia the trachea with 1 mL of sterile silica dust suspensions (40 g/L) and 1 mL of normal saline. At 2 days after modeling, 2.2×106 transfected bone marrow mesenchymal stem cels were injected via the trachea into the rats of control group and silica dust exposure group. Rats were kiled at weeks 1, 2, 3, 4 after transplantation, and the distribution and intensity of green fluorescence in the lung, heart, liver, spleen, kidney, and brain tissue were observed under the fluorescence microscopy by frozen sections and analyzed using imaging analysis software. RESULTS AND CONCLUSION: When the multiplicity of infection was 50, there were no significant differences between the viability and proliferation activity of the transfected and untransfected cels (P > 0.05). After transplantation of transfected bone marrow mesenchymal stem cels, strong green fluorescence was observed widely in the lung, especialy around the bronchus and blood vessels, and stil obvious at the 4th week. The fluorescence of other organs also could be observed at the 1st week. It was strong and wide in the liver, spleen and heart, while faint and less in the kidney and brain, and al reduced with time. It shows bone marrow mesenchymal stem cels transplantedvia the trachea into rats exposed to silica dust can be homing to the injured lung of rats.

Neural stem cell transplantation for central nervous system diseases via the cerebrospinal fluid / 中国组织工程研究

BACKGROUND:Currently, neural stem celltransplantation can be performed through three main approaches:local lesions, blood circulation, and cerebrospinal fluid. OBJECTIVE:To review the transplantation of neural stem cells or neural precursor cells via the cerebrospinal fluid in the treatment of central nervous system diseases. METHODS:A computer-based search of PubMed and CHKD databases was performed to retrieve articles concerning transplantation of neural stem cells via the cerebrospinal fluid, and its application and therapeutic mechanism in the treatment of central nervous system diseases in both animal experiment and clinic study published from 2000 to 2009. RESULTS AND CONCLUSION:It is suitable for neural stem cellsurvival, proliferation, and differentiation in the cerebrospinal fluid. Transplantation of neural stem cells via the cerebrospinal fluid is effective and feasible to treat central nervous system diseases. However, some problems have not been solved, such as the source of neural stem cells, the optimal time window and celldose, the safety and the long-term effect. Further studies are needed to pave the way for the intrathecal injection of neural stem cells in the treatment of central nervous system diseases.
