RESUMEN

Desde los años ochenta se ha explorado el tratamiento para el virus de la hepatitis C, aunque en ese entonces los medicamentos disponibles eran poco toleradas y poco eficaces. En el 2011, la introducción de antivirales de acción directa transformó significativamente el curso de la enfermedad, logrando tasas de curación superiores al 90 % en los pacientes. Este avance ha permitido prevenir complicaciones futuras con efectos adversos mínimos. La presente revisión aborda la línea de tiempo del descubrimiento de los antivirales, su mecanismo de acción, sus indicaciones y potencial impacto en la salud pública.


Since the 1980s, the treatment of hepatitis C has been explored, although at that time, the available medications were poorly tolerated and ineffective. In 2011, the introduction of direct-acting antivirals significantly transformed the course of the disease, achieving cure rates of over 90% in patients. This advance has made it possible to prevent future complications with minimal adverse effects. This review addresses the timeline of the discovery of antivirals, their mechanism of action, and their impact on medicine.

RESUMEN

ABSTRACT A 60-year-old-male with refractory relapsed multiple myeloma presented with redness, pain, foreign body sensation, and blurred vision in both eyes that gradually increased after his third belantamab mafotodin infusion. Biomicroscopy revealed bilateral microcyst-like epithelial changes and epithelial crystal-like deposits, whereas in vivo confocal microscopy revealed intraepithelial and subepithelial hyperreflective deposits in corneal epithelium. Belantamab mafodotin therapy was discontinued for seven weeks due to corneal toxicity, which cleared progressively. We aim to demonstrate belantamab mafodotin-related corneal toxicity that may be detected using slit lamp and in vivo confocal biomicroscopy.


RESUMO Um homem de 60 anos, diagnosticado com mieloma múltiplo recidivante refratário, apresentou vermelhidão, dor, sensação de corpo estranho e visão turva em ambos os olhos, aumentando gradualmente após sua terceira infusão de belantamabe mafodotina. À biomicroscopia, foram observadas alterações epiteliais bilaterais semelhantes a microcistos e depósitos epiteliais semelhantes a cristais. A microscopia confocal in vivo revelou depósitos hiper-refletivos intraepiteliais e subepiteliais na córnea. Devido à toxicidade corneana, a terapia com belantamabe mafodotina foi interrompida por sete semanas e a toxicidade foi gradualmente resolvida. Nosso objetivo é demonstrar os achados à biomicroscopia confocal in vivo e à lâmpada de fenda da toxicidade corneana relacionada ao belantamabe mafodotina.

RESUMEN

Abstract In dermatologists' clinical practice, the use of systemic glucocorticoids is recurrent for the management of different comorbidities that require chronic immunosuppression. The prescription of this medication requires caution and basic clinical knowledge due to the several adverse effects inherent to the treatment. However, different doubts may arise or inappropriate conduct may be adopted due to the lack of objective and specific guidelines for the screening, prophylaxis and management of complications from chronic corticosteroid therapy. Considering this problem, the authors carried out a narrative review of the literature to gather up-to-date data on adverse effects secondary to the chronic use of systemic glucocorticoids. The broad approach to this topic made it possible to review the pathophysiology and risk factors for these complications, as well as to develop updated orientation that can be used as a learning tool and quick reference for dermatologists during their clinical practice with glucocorticoids.

RESUMEN

ABSTRACT Bilateral acute depigmentation of the iris and bilateral acute iris transillumination (BAIT) are similar clinical entities. The former causes acute-onset depigmentation of the iris stroma without transillumination, whereas the latter causes depigmentation of the iris pigment epithelium with transillumination. The etiopathogenesis of these conditions is not yet fully understood, but the proposed causes include the use of systemic antibiotics (especially moxifloxacin) and viral triggers. We present a case series of five female patients with a mean age of 41 (32-45) years, all of whom suffered acute onset of bilateral pain and redness of the eyes after moxifloxacin use (oral or topical). It is important for ophthalmologists to be aware of the two forms of iris depigmentation since this case series suggests that SARS-CoV-2 or its empirical treatment with moxifloxacin may trigger iris depigmentation. If this is the case, clinicians will likely see increased incidences of bilateral acute depigmentation of the iris and bilateral acute iris transillumination during and after the COVID-19 pandemic.

RESUMEN

ABSTRACT OBJECTIVE To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil. METHODS This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis. RESULTS For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal. CONCLUSIONS The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.

RESUMEN

ABSTRACT The authors report full-field electroretinogram and optical coherence tomography findings of intravitreal melphalan retinal toxicity. An 18-month-old girl with unilateral group D retinoblastoma was evaluated with light-adapted 3 full-field electroretinogram protocol and optical coherence tomography (I-Stand optical coherence tomography, Optovue) after treatment with intravitreal melphalan for active vitreous seeds. After the third injection, the child developed retinal pigment epithelial changes near the injection site. The photopic response of the full-field electroretinogram standard flash cones showed a decrease in amplitude responses of waves a and b in the affected eye compared to the contralateral eye. Optical coherence tomography showed loss of photoreceptors and outer nuclear layers in the affected eye. Melphalan toxicity is dose-dependent, and despite its treatment benefits, it can affect vision. Our case shows an updated, in-depth retinal toxicity assessment of intravitreal melphalan in the human retina with optical coherence tomography and its correlation with electroretinogram changes.


RESUMO Os autores relatam os achados de eletrorretinograma de campo total e tomografia de coerência óptica (OCT) da toxicidade retiniana ao melfalan intravítreo. Menina de 18 meses com retinoblastoma foi avaliada com fases fotópicas do eletrorretinograma de campo total e tomografia de coerência óptica após o tratamento com melfalan intravítreo. Após a terceira injeção, a criança desenvolveu alterações do epitélio pigmentar da retina próximo ao local da injeção. A resposta fotópica do eletrorretinograma de campo total mostrou diminuição da amplitude das respostas das ondas a e b no olho afetado comparado com o olho sadio. A tomografia de coerência óptica mostrou alterações significativas nas camadas retinianas externas no olho comprometido. A toxicidade do melfalan é dose dependente e, apesar dos benefícios terapêuticos, podem causar alterações retinianas significativas. Este caso demonstra uma avaliação atual e aprofundada da toxicidade retiniana do melfalan intravítreo na retina humana através da tomografia de coerência óptica e sua correlação com as alterações no eletrorretinograma.

RESUMEN

ABSTRACT Neuroleptic malignant syndrome (NMS) is a neurologic emergency potentially fatal. This rare side effect is most commonly associated with first-generation antipsychotics and less frequently with atypical or second-generation antipsychotics. The diagnosis relies on both clinical and laboratory criteria, with other organic and psychiatric conditions being ruled out. CASE REPORT: A 39-year-old female patient, who is institutionalized and completely dependent, has a medical history of recurrent urinary infections and colonization by carbapenem-resistant Klebsiella pneumoniae. Her regular medication regimen included sertraline, valproic acid, quetiapine, risperidone, lorazepam, diazepam, haloperidol, baclofen, and fentanyl. The patient began experiencing dyspnea. Upon physical examination, she exhibited hypotension and a diminished vesicular murmur at the right base during pulmonary auscultation. Initially, after hospitalization, she developed high febrile peaks associated with hemodynamic instability, prompting the initiation of antibiotic treatment. Despite this, her fever persisted without an increase in blood inflammatory parameters, and she developed purulent sputum, necessitating antibiotherapy escalation. The seventh day of hospitalization showed no improvement in symptoms, suggesting NNMS as a differential diagnosis. All antipsychotic and sedative drugs, as well as antibiotherapy, were discontinued, after which the patient showed significant clinical improvement. CONCLUSION: Antipsychotic agents are commonly employed to manage behavioral changes linked to various disorders. However, their severe side effects necessitate a high degree of vigilance, the cessation of all medications, and the implementation of supportive care measures. A prompt and accurate diagnosis of NMS is crucial to alleviating the severe, prolonged morbidity and potential mortality associated with this syndrome.

RESUMEN

ObjectiveTo systematically evaluate the safety of Tianzhi granules used in the treatment of mild-to-moderate vascular dementia. MethodA randomized, double-blind, double-simulated, positive drug/placebo parallel controlled multi-center phase Ⅳ clinical trial and an open multi-center phase Ⅳ clinical trial of Tianzhi granules in the treatment of mild-to-moderate vascular dementia were conducted. Safety data of 1 492 patients were included and analyzed according to inclusion and exclusion criteria. The main evaluation measures were the incidence rate of adverse events/adverse reactions, laboratory indicators, vital signs, and electrocardiogram (ECG) results. ResultA total of six adverse events possibly related to the test drug occurred in 520 patients of the double-blind trial, and the symptoms were all mild and recovered. The incidence of adverse events was not statistically different among Tianzhi granules, donepezil, and placebo groups. Nine adverse events possibly related to the test drug were observed in 972 patients of the open trial, and the symptoms were mild and recovered. Laboratory tests (blood routine, urine routine, liver function, kidney function, and coagulation) and vital signs were compared before treatment (baseline) and after treatment of 12 and 24 weeks, respectively. There was no statistical significance in the main indicators before and after treatment. In the double-blinded trial, there was no significant difference in safety indicators between different groups before and after treatment. The most frequent adverse reaction was gastrointestinal discomfort, with an incidence rate of 6.64‰. ConclusionAdverse reactions occasionally occur in patients using Tianzhi granules, and it is safe to use Tianzhi granules to treat mild-to-moderate vascular dementia clinically.

RESUMEN

A vasculite leucocitoclástica é uma patologia cujos mecanismos estão associados ao processo de inflamação vascular. Estima-se que até 24% dos casos de vasculite estão relacionados ao uso de fármacos, sendo os antimicrobianos beta-lactâmicos um dos grupos farmacológicos comumente associados a este desfecho adverso. A oxacilina, uma penicilina semissintética, possui um anel beta-lactâmico que confere atividade biológica e está associada com maior frequência a relatos de vasculite leucocitoclástica. No entanto, casos semelhantes relacionados a esse antimicrobiano são raros, sendo identificados apenas três casos na literatura. Diante desse contexto, relatamos um quarto caso de vasculite leucocitoclástica em um homem de 56 anos, em tratamento com oxacilina, que desenvolveu a vasculite no 3º dia de uso do antimicrobiano. Além da suspensão da oxacilina, ele foi tratado com 125 mg/dia de metilprednisolona endovenosa por sete dias, seguido de 20 mg/dia de prednisona oral por quatro dias, resultan-do em remissão satisfatória das lesões cutâneas e ausência de novos desfechos adversos. Este caso corrobora a possível relação causal entre o uso de oxacilina e o desenvolvimento da vasculite leucocitoclástica, apesar de sua ocorrência ser rara. A resposta favorável às intervenções terapêuticas, incluindo a suspensão da oxacilina e o uso de corticosteroides, destaca a eficácia dessas abordagens no tratamento dessa complicação (AU).


Leukocytoclastic vasculitis is a pathology whose mechanisms are associated with the process of vascular inflammation. It is estimated that up to 24% of the cases of vasculitis are drug-related, with beta-lactam antimicrobials be-ing one of the pharmacological groups commonly associated with this adverse outcome. Oxacillin, a semisynthetic penicillin, has a beta-lactam ring that confers biological activity and is most frequently associated with reports of leukocytoclastic vasculitis. However, similar cases related to this antimicrobial are rare, with only three cases identified in the literature. Against this background, we report a fourth case of leukocytoclastic vasculitis in a 56-year-old man, on oxacillin treatment, who developed the vasculitis on the 3rd day of antimicrobial use. In addition to oxacillin suspension, he was treated with 125 mg/day of intravenous methylprednisolone for seven days, followed by 20 mg/day of oral prednisone for four days, resulting in satisfactory remission of the skin lesions and no new adverse outcomes. This case provides further evidence supporting the potential causal relationship between the use of oxacillin and the development of leukocytoclastic vasculitis, albeit a rare occurrence. The positive response to therapeutic interventions, such as oxacillin suspension and corticosteroid treatment, underscores the effectiveness of these approaches in addressing this complication (AU),

RESUMEN

Abstract Objective: to build and validate a clinical simulation scenario on hospital nurse managerial decision-making competence for undergraduate nursing students. Method: a descriptive and methodological study was carried out in a higher education institution, with the participation of 10 judges and five players. To do so, the conceptual simulation model proposed by Jeffries and standards of the International Nursing Association for Clinical Simulation and Learning were used to prepare the scenario and the checklist. Results: the scenario was called "Managerial decision-making of nurses in the face of adverse events in a hospital". The scenario script and checklist were built for validation. The checklist was face- and content-validated. Afterward, judges used the checklist to validate the scenario, which, in its final version, was composed of Prebriefing (seven items), Scenario in Action (18 items) and Debriefing (seven items). Conclusion: the scenario proved to be a teaching strategy that anticipates the reality of future nurses, bringing them the self-confidence to perform their activities and helping them to act critically and reflectively during decision-making processes.

RESUMEN

As irregularidades menstruais representam uma série de desordens na quantida- de, duração, frequência ou regularidade do sangramento uterino. Entre suas cau- sas destaca-se o sangramento secundário ao uso de anticoncepcionais, uma razão frequente de descontinuidade dos contraceptivos, podendo aumentar as taxas de gestações não planejadas. Boa parte dos contraceptivos pode levar a mudanças no padrão de sangramento uterino, e a abordagem inicial do sangramentos irregula- res inclui a avaliação de outras possíveis causas, o reforço do uso correto da medi- cação, a tranquilização da paciente quanto à benignidade do quadro e à tendência a melhora com a continuidade do uso. Os anti-inflamatórios podem ser usados como estratégia inicial, e, não havendo resposta satisfatória, há alternativas espe- cíficas para cada método. Este trabalho visa identificar as recomendações atuais sobre o manejo do sangramento anormal decorrente de contraceptivos, por meio de revisão narrativa de estudos publicados sobre o tema nos últimos vinte anos.


Abnormal uterine bleeding represents a series of disorders in the amount, du- ration, frequency and or regularity of uterine bleeding. Among its causes, uterine bleeding secondary to the use of contraceptives stands out as a frequent reason for contraceptive discontinuity, which could lead to unplanned pregnancies. Most contraceptives can cause changes in the pattern of uterine bleeding, and the ini- tial approach of the abnormal bleeding includes assessing other possible cau- ses, reinforcing the correct use of medication, and reassuring the patient about the benignity of the condition and the tendency to improve with the continuity of the treatment. Anti-inflammatory drugs can be used as an initial strategy, and, if there is no satisfactory answer, there are specific alternatives for each contracep- tive method. This work aims to identify them current recommendations on the management of abnormal bleeding resulting from contraceptives use, through a narrative review of studies published on the subject in the last twenty years.

RESUMEN

Abstract The frequency of the use of drugs that act on the epidermal growth factor receptor (EGFR) is increasing, with the consequent onset of cutaneous toxicity, specifically acneiform eruption. The authors extensively review the topic, focusing on describing how these drugs can affect the skin and its appendages, that is, the pathophysiology that encompasses the cutaneous toxicity related to the use of EGFR inhibitors. In addition, it was possible to list the risk factors that may be associated with adverse effects of these drugs. Based on this recent knowledge, the authors expect to aid in the management of patients who are more vulnerable to toxicity, reduce morbidities, and improve the quality of life of patients undergoing treatment with EGFR inhibitors. Other issues related to the toxicity of EGFR inhibitors, such as the clinical aspects of the acneiform eruption grades, and other different types of cutaneous and mucosal reactions, are also included in the article.

RESUMEN

Objetivo: El propósito de este trabajo es estudiar la prevalencia de eventos adversos medicamentosos (EAM) en pacientes hospitalizados durante el período 2019-2020 en Chile. Además, como parte de la investigación, se realizó una validación del método que etiqueta la ocurrencia de EAM en base a los diagnósticos de egreso de los casos analizados. Diseño: La prevalencia de EAM fue estudiada para cerca de 1,7 millones de pacientes, para los cuales se analizó, además de los diagnósticos CIE10 de egreso, información sociodemográfica e indicadores de resultado sanitario de la atención, tales como el peso GRD, largo de estadía y mortalidad. Para la validación del método de identificación de EAM, se seleccionó una muestra aleatoria representativa estratificada por sexo y especialidad médica del año 2019 en un hospital público de Chile, cuyos resúmenes de egreso fueron analizados por un grupo de expertos de forma retrospectiva. Resultados: Los resultados muestran una prevalencia de EAM u otras sustancias de 2,7% y 3,1% en los egresos hospitalarios de los años 2019 y 2020 a nivel nacional y una precisión del instrumento de al menos un 83,3% (IC 90%). Conclusiones: Este estudio permite describir un fenómeno por medio de la estimación basada en datos reales, el cual es esencial para el diseño de políticas públicas en salud y estudios que apunten a enriquecer la calidad y seguridad del paciente.


Objective: To study the prevalence of adverse drug events (ADE) in hospitalized patients in Chile. As part of our research, we also assessed the validity of the method used to identify the occurrence of an ADE based on the discharge diagnoses of the patient. Design: The study included 1,7 million patients hospitalized during 2019-2020. We analyzed the following variables for each patient: ICD-10 discharge diagnoses, sociodemographic information, and clinical outcome indicators, i.e., diagnosis-related group (DRG) weight, length of stay, and mortality. To validate the method for the identification of ADEs, first, we generated a random representative sample of patients, stratified by sex and medical specialty, hospitalized in a Chilean public hospital in 2019, and then we compared the outcome of the method with the opinion of a group of clinical experts that reviewed each patient's discharge summary retrospectively. Results: The prevalence of ADEs in hospitalized patients in Chile during 2019 and 2020 was 2,7% and 3,1%, respectively. The precision of the method used to identify ADEs was 83,3% or higher (CI 90%). Conclusions: This paper uses nationwide data to describe the prevalence of ADEs and their correlation with different factors associated with the patient, the patient's disease, and the health service. These studies are essential to designing public health policies that effectively address healthcare quality and patient safety.

RESUMEN

Abstract Introduction Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. Methods MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. Results The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. Conclusion There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

Materiales y Método: Estudio de serie de casos en Farmacovigilancia (FV). Se revisó la base de datos de reportes de sospecha de reacciones adversas a los medicamentos de la Unidad Coordinadora Provincial de Farmacovigilancia, entre 2014 y 2019. Resultados: Se evaluaron un total de 1926 reportes de reacciones adversas por medicamentos en ancianos, representaron el 24,3 % del total. Predominaron las mujeres (56,7 %) y el grupo de edad entre 60 y 69 años (51,4%). Prevaleció la erupción cutánea (13,4 %). Los antimicrobianos y los antiinflamatorios no esteroideos, fueron los que se asociaron más con las RAM en piel, así como del sistema digestivo. La tos estuvo relacionada con el captopril. Predominaron las reacciones adversas por medicamentos de baja frecuencia (55,2%), moderadas (83,8%) y las probables (77,1%) según imputabilidad. Conclusiones: El perfil de seguridad en ancianos en la provincia de Matanzas muestra un predominio de reacciones adversas frecuentes, moderadas y probables en mujeres con edades entre 60 a 69 años.

RESUMEN

Resumen La información sobre reacciones adversas es fundamental para conocer la seguridad real de los medicamentos comercializados. Existen casos de pacientes con síndrome de intolerancia a múl tiples drogas, una entidad poco reportada, la que puede presentarse cuando en un mismo paciente ocurren reacciones adversas a más de dos medicamentos no relacionados farmacológicamente. Se describe el caso de una mujer con diagnóstico de endocarditis por Staphylococcus aureus multisensible, que cursó con reacciones adversas a cinco antibióticos estructuralmente no relacionados y con mecanismos de acción diferentes, en dos internaciones consecutivas. Las reacciones fueron secundarias a cefazolina (tricitopenia), vancomicina (injuria renal), daptomicina (elevación de creatina fosfoquinasa) y linezolid (hepatotoxicidad) en la primera internación, y a cotrimoxazol (plaquetopenia) en la segunda. En todos los casos se observó daño transitorio en diferentes sistemas de órganos. Finalmente, se otorgó alta hospitalaria con clindamicina sin nuevas intercurrencias hasta finalizar tratamiento. Este caso podría corresponder al síndrome antes mencionado o a una entidad aún no caracterizada.


Abstract Adverse reaction reporting is essential to understand the actual safety of marketed medicines. There are cases of patients with multidrug intolerance syndrome, an under-reported entity, which can occur when adverse reactions to more than two pharmacologically unrelated drugs occur in the same patient. We describe the case of a woman diagnosed with multisensitive Staphylococcus aureus endocarditis who experienced adverse reactions to five structurally unrelated antibiotics with different mechanisms of action in two consecutive hospitalisations. The reactions were secondary to cefazolin (tricytopenia), vancomycin (renal injury), daptomycin (elevated creatine phosphokinase) and linezolid (hepatotoxicity) in the first hospitalization, and to cotrimoxazole (thrombocytopenia) in the second. Transient damage to different organ systems was observed in all cases. Finally, hospital discharge was granted with clindamycin without further intercurrences until treatment was completed. This case could cor respond to the aforementioned syndrome or to an as yet uncharacterized entity.

RESUMEN

Abstract Introduction The demand for apheresis platelets has increased in the recent past and the shrinking donor pool has shifted the trend to collection of double-dose or higher yield of platelets. Objective The present study aimed to determine the effect of double-dose plateletpheresis on the target yield and donor platelet recovery. Methods The study was conducted on 100 healthy plateletpheresis donors, 50 of whom were in the study group, which underwent double-dose plateletpheresis (DDP), and 50 of whom were in the control group for single-donor plateletpheresis. Pre- and post-procedure samples of donors were subjected to a complete blood count. The DDP product was sampled for platelet yield and then split into two parts. Platelet yield, collection efficiency, collection rate, recruitment factor and donor platelet loss were calculated. Results The mean platelet yield in the SDP was 4.09 ± 1.15 × 1011 and in the DDP, 5.93 ± 1.04 × 1011. There was a significant correlation between the pre-donation platelet count and platelet yield. The total of platelets processed for the SDP were 5.42 ± 1.08 × 1011 and for the DDP, 7.94 ± 0.77 × 1011. The collection efficiency was 71.93 ± 25.14% in the SDP and 72.94 ± 16.28% in the DDP, while the collection rates were 0.78 × 1011 and 0.94 × 1011 per minute, respectively. The average recruitment factor observed was 0.98 in the SDP, while it was 0.99 in the DDP. The mean platelet loss observed in the SDP was 35.55 ± 8.53% and in the DDP, 37.76 ± 8.65%. Conclusion The double-dose plateletpheresis supplements the platelet inventory in developing countries where the apheresis donor pool is limited. It is prudent to ensure stringent donor selection criteria for donors donating high-yield platelet products, thus enhancing donor safety and retention.
