ABSTRACT

Durante la pandemia por COVID-19 se observaron diversas reacciones adversas a fármacos. Esto pudo haber estado relacionado con una mayor susceptibilidad inmunológica de los pacientes con SARS-CoV-2 a presentar este tipo de cuadros, así como también con la exposición a múltiples medicamentos utilizados en su tratamiento. Comunicamos el caso de un paciente con una infección respiratoria grave por COVID-19, que presentó 2 reacciones adversas graves a fármacos en un período corto de tiempo. (AU)


During the COVID-19 pandemic, various adverse drug reactions were observed. This could have been related to a greater immunological susceptibility of patients with SARS-CoV-2 to present this type of symptoms, as well as exposure to multiple drugs used in their treatment. We report the case of a patient with a severe respiratory infection due to COVID-19, who presented 2 serious adverse drug reactions associated with paracetamol in a short period of time. (AU)

ABSTRACT

OBJECTIVE@#To investigate the predictive value of complete blood count (CBC) and inflammation marker on the recurrence risk in children with Henoch-Schönlein purpura (HSP).@*METHODS@#One hundred and thirty-three children with HSP admitted to Cangzhou Central Hospital from February 2017 to March 2019 were enrolled. The clinical data of the children were collected, at the time of admission CBC and C-reactive protein (CRP) were detected. After discharge, the children were followed up for 1 year, the clinical data of children with and without recurrence were compared, and multivariate logistic regression was used to analyze the risk factors affecting HSP recurrence. Receiver operating characteristic (ROC) curve should be drawn and the predictive value of CBC and CRP on HSP recurrence should be analyzed.@*RESULTS@#In the follow-up of 133 children, 8 cases were lost and 39 cases recurred, with a recurrence rate of 31.20% (39/125). The age, skin rash duration, proportion of renal damage at the initial onset, percentage of neutrophils, percentage of lymphocytes, platelet count (PLT), mean platelet volume (MPV) and neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), MPV/PLT ratio (MPR), and CRP level of patients with recurrence were statistically different from those without recurrence (P <0.05). Multivariate logistic regression analysis showed that long skin rash duration, renal damage at the initial onset, increased PLR, high PLT, increased MPV and elevated CRP level were independent risk factors for recurrence in children with HSP (P <0.05). The ROC curve analysis showed that the area under the curve (AUC) of the combination of the four blood and inflammation marker (PLT, MPV, PLR and CPR) in the early prediction of HSP recurrence was 0.898, which was higher than the initial renal damage (AUC=0.687) and persistent skin rash time (AUC=0.708), with a sensitivity of 84.62% and a specificity of 83.72%.@*CONCLUSION@#Observation of CBC and CPR can predict the risk of HSP recurrence early and guide early clinical intervention.

ABSTRACT

Descrever os casos suspeitos de sarampo e rubéola notificados no Sistema de Informação de Agravos de Notificação (Sinan), Brasil, 2007 a 2016. Métodos: Os dados foram extraídos do Sinan, referentes aos anos de 2007 a 2016. As variáveis utilizadas foram os números de notificações de casos de sarampo e rubéola por regiões e ano, idade, sexo, hospitalização, estado gestacional, histórico vacinal, realização de bloqueio vacinal, coletas sorológicas (S1 e S2), sinais e sintomas, investigação adequada, critério de confirmação ou descarte e classificação final do caso. Resultados: Entre 2007 e 2016 houve 127.802 casos suspeitos de sarampo e rubéola notificados. Aproximadamente 92% dos casos foram investigados, a maioria em menores de cinco anos. Os sintomas mais frequentes foram tosse (40%) e coriza (38%). Como instrumento de vigilância foi coletado sangue para confirmação laboratorial em 87% das notificações. A maioria dos casos de sarampo ocorreu entre os anos de 2011 e 2015, relacionados a casos importados, totalizando 1.443 casos; para rubéola, 10.125 casos foram confirmados. Foram descartados 1,3% (1.698/127.802) e 5,1% (6.555/127.802) das notificações de sarampo e rubéola, respectivamente. Foram ignorados 9% (11.523/127.802) para sarampo e 49% (62.978/127.802) para rubéola. Conclusão: A vigilância dos casos de doenças exantemáticas permitiu demonstrar a situação dos casos de doenças exantemáticas circulantes no país como importante ferramenta de saúde pública. O grande número de casos descartados classificados como ignorados merece atenção, no sentido de melhorar o encerramento dos casos suspeitos notificados


To describe the suspected cases of measles and rubella notified in the Notifiable Diseases Information System (Sinan), Brazil, from 2007 to 2016. Methods: Data were extracted from Sinan referring to the years 2007 to 2016. The variables used were the number of notifications of measles and rubella cases by region and year, age, gender, hospitalization, gestational status, vaccination history, vaccination blockade, serological collections (S1 and S2), signs and symptoms, adequate investigation, confirmation criteria or disposal and final case classification. Results: Between 2007 and 2016, there were 127,802 suspected cases of measles and rubella reported. Approximately 92% of cases were investigated, mostly in children under five years of age. The most frequent symptoms were cough (40%) and runny nose (38%). As a surveillance tool, blood was collected for laboratory confirmation in 87% of notifications. Most Measles cases occurred between 2011 and 2015, related to imported cases, totaling 1,443 cases; for Rubella 10,125 cases were confirmed. 1.3% (1,698/127,802) and 5.1% (6,555/127,802) of measles and rubella notifications, respectively, were discarded. 9% (11,523/127,802) for measles and 49% (62,978/127,802) for rubella were ignored. Conclusion: Surveillance of cases of exanthematous diseases allowed demonstrating the situation of cases of exanthematous diseases circulating in the country as an important public health tool. The large number of discarded cases classified as ignored deserves attention, in order to improve the closing of notified suspected cases

ABSTRACT

Introducción. El dengue es un problema de salud pública a nivel mundial. Confinado en sus orígenes a las zonas tropicales y subtropicales, en la actualidad se presenta en otras regiones como Argentina. Desde el año 2008 se presenta con brotes epidémicos en la Ciudad Autónoma de Buenos Aires, con escasos reportes en niños. Objetivo. Analizar y comparar las características clínicas, epidemiológicas, de laboratorio y evolutivas de los dos últimos brotes de dengue fuera del área endémica. Población y métodos. Estudio de series temporales. Se incluyeron pacientes menores de 18 años con dengue probable o confirmado, evaluados en un hospital pediátrico de la Ciudad de Buenos Aires durante los períodos 2015-2016 y 2019-2020. Resultados. Se incluyeron 239 pacientes, 29 (12 %) con antecedente de viaje. La mediana de edad fue de 132 meses (rango intercuartílico: 102-156). Todos tuvieron fiebre. Otros síntomas fueron: cefalea en 170 (71 %), mialgias en 129 (54 %) y exantema en 122 (51 %). Cuarenta pacientes (17 %) tenían comorbilidades. Presentaron signos de alarma 79 pacientes (33 %) y 14 (6 %) tenían dengue grave. Requirieron internación 115 pacientes (45 %) y ninguno falleció. El serotipo DENV-1 fue el más frecuente. El antecedente de viaje y la necesidad de internación predominaron en el primer período; el dengue grave y la infección previa, en el segundo. Conclusiones. Ningún paciente falleció de dengue en los períodos estudiados. Se observaron diferencias estadísticamente significativas en la frecuencia de internación; el antecedente de viaje fue más frecuente en el período 2015-2016 y el dengue grave, en el 2019-2020.


Introduction. Dengue is a public health problem worldwide. It was originally confined to tropical and subtropical areas, but it is now present in other regions, such as Argentina. Epidemic outbreaks have been observed in the City of Buenos Aires since 2008, with few reports in children. Objective. To analyze and compare the clinical, epidemiological, laboratory, and evolutionary characteristics of the latest 2 dengue outbreaks outside the endemic area. Population and methods. Time-series study. Patients under 18 years of age with probable or confirmed dengue and evaluated in a children's hospital of the City of Buenos Aires during the periods 2015-2016 and 2019-2020 were included. Results. A total of 239 patients were included; 29 (12%) had a history of travel. Their median age was 132 months (interquartile range: 102156). All had a fever. Other symptoms included headache in 170 (71%), myalgia in 129 (54%), and rash in 122 (51%). Forty patients (17%) had comorbidities.

ABSTRACT

Introdução: Doenças exantemáticas (DE) são patologias infecciosas agudas, que têm como característica principal a manifestação dermatológica. Entre elas, sarampo e rubéola são de notificação compulsória. A permanência da circulação destes vírus no mundo tem causado surtos em diversas regiões, como em SC, embora sejam doenças evitáveis por meio da imunização. Métodos: Trata-se de um estudo de delineamento ecológico, constituído de casos notificados por DE em SC no período de 2009 a 2019. Os dados foram coletados no Sistema Nacional de Agravos e Notificações (SINAN/DATASUS). Resultados: Foram notificados 190 casos de DE, 41,57% na faixa etária de 20 a 29 anos, 55,91% masculinos, 88,70% brancos e 2,15% gestantes. Houve confirmação laboratorial em 85,16%, e 72,72% foram causados pelo vírus sarampo selvagem. Exantema predominou em novembro em 46,77%, e febre em outubro, em 41,93%. Tosse esteve presente em 89,24%, coriza em 67,20% e conjuntivite em 50,53%. A macrorregião com maior média de cobertura vacinal foi a Grande Oeste, com 86,85%, e a menor, a Grande Florianópolis, com 72,07%. A maior incidência de sarampo ocorreu em 2019 no Nordeste e Planalto Norte com 11,34, e a de rubéola 0,13 no Grande Oeste no mesmo ano. Foi realizado bloqueio vacinal em 95,34% dos casos, e 64,28% foram autóctones. Conclusão: Observou-se que as DE acometem indistintamente ambos os sexos, etnias e idades, sendo a vacinação a forma mais eficaz de prevenir surtos. A reemergência ocorrida no estado foi consequência das baixas taxas de cobertura vacinal, apontando para a necessidade de melhorias nas ações de imunização.


Introduction: Exanthematous diseases (ED) are acute infectious pathologies that present mainly dermatological manifestations. Among them, measles and rubella demand compulsory notification. The continued circulation of these viruses has caused outbreaks in several regions, such as Santa Catarina, although they are preventable diseases through immunization. Methods: This is a study of ecological design consisting of cases notified of ED in SC from 2009 to 2019. Data collection from the National System of Diseases and Notifications (SINAN/DATASUS). Results: 190 cases of ED were notified, 41.57% in the age group 20 to 29 years, 55.91% male, 88.70% white, and 2.15% pregnant women. Laboratory confirmation occurred in 85.16%, and the wild measles virus was the cause in 72.72%. Exanthema predominated in November with 46.77% and fever in October with 41.93%. Cough was present in 89.24%, coryza in 67.20%, and conjunctivitis in 50.53%. The macro-region with the highest average vaccination coverage was the great west, 86.85%, and the lowest was greater Florianópolis, 72.07%. The highest incidence of measles occurred in 2019. Northeast and North Plateau scored 11.34, and rubella at 0.13 in the Great West in the same year. Vaccine block occurred in 95.34% of cases, and 64.28% were autochthonous. Conclusions: The study observed that EDs affect both sexes, ethnicities, and ages indistinctly, and vaccination is the most effective way to prevent outbreaks. The re-emergence that occurred in the state was a consequence of low rates of vaccination coverage, pointing to the need for improvements in immunization activities

ABSTRACT

Abstract Generalized pustular psoriasis (von Zumbusch) is a rare and acute eruption characterized by multiple sterile pustules over an erythematous and edematous background, eventually associated with psoriasis vulgaris. Classically, it manifests as a potentially severe systemic picture and demands prompt diagnosis and intervention. The duration of each flare-up and intervals between the pustular episodes is extremely variable. Recently, genetic abnormalities have been identified mainly in the familial and early variants of this disease. The therapeutic arsenal is limited; however, new drugs being evaluated aim to control both pustular flare-ups and disease recurrences.

ABSTRACT

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a benign, self-limited, immune-mediated, symmetric erythematous rash involving the buttocks and other intertriginous/flexural areas, observed after systemic exposure to a drug in an individual with or without prior sensitization. We present a 70-year old patient, who presented SDRIFE after the administration of piperacillin-tazobactam which improved rapidly after its suspension.


El exantema intertriginoso y flexural simétrico relacionado con fármacos (SDRIFE, por su sigla en inglés) es una erupción eritematosa simétrica, inmunomediada, benigna y autolimitada, que compromete glúteos y otras áreas intertriginosas, flexurales o ambas, y que se observa luego de la exposición sistémica a un fármaco en un individuo con sensibilización previa o sin ella. Se comenta el caso clínico de un paciente de 70 años de edad, que presentó SDRIFE posterior a la administración de piperacilina-tazobactam y que mejoró rápidamente luego de su suspensión.

ABSTRACT

Las manifestaciones cutáneas relacionadas a la infección por el coronavirus SARS-CoV-2, causante de COVID-19, se han descrito entre el 0,2% y 20,4% de las personas que cursan con esta enfermedad. Las más frecuentemente descritas son: lesiones maculopapulares (47%), lesiones acrales eritematosas con vesículas o pústulas (pseudoperniosis) (19%), urticariales (19%), lesiones vesiculosas (9%) y livedo/necrosis (6%). En particular, la pitiriasis rosada es una dermatosis autolimitada de etiología desconocida, sin embargo, se ha visto asociada a la infección por SARS-CoV-2, con algunos reportes de casos en la literatura. El mecanismo fisiopatológico de las lesiones cutáneas en COVID-19 no es claro, y se han planteado algunas teorías, entre las cuales está el papel que juega la enzima convertidora de angiotensina 2 (ACE2) utilizada por el virus para infectar las células, los infiltrados linfocíticos, los depósitos de factores del complemento en la piel, y la reactivación de virus latentes como los herpes virus humanos. Se presenta el caso de una paciente con pitiriasis rosada asociada a COVID-19 y se describen los casos reportados hasta la fecha

ABSTRACT

A Síndrome de DRESS (do inglês, Drug Rash with Eosinophilia and Systemic Symptoms) é uma patologia rara que consiste em uma severa reação medicamentosa mediada por células T. O presente relato de caso retrata uma paciente do sexo feminino, 59 anos, que apresentou icterícia, febre não termometrada, acolia, colúria, mialgia, placas hipercrômicas e lesões pruriginosas. Referiu uso recente de alopurinol, paracetamol e nimesulida, apresentando melhora importante e espontânea após a suspensão das medicações. A extensão do tempo de exposição ao medicamento agressor ocasiona um maior período de internação e risco de mortalidade. Além disso, os dados restritos sobre a Síndrome de DRESS impõe desafios ao seu diagnóstico. Sendo assim, este estudo busca destacar a importância do diagnóstico clínico precoce, a suspensão do medicamento agressor e a instituição da terapêutica adequada para um prognóstico favorável


The Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) Syndrome is a rare pathology that consists of a severe drug reaction mediated by T cells. The present case report depicts a female patient, 59 years old, who presented jaundice, non thermometered fever, acholia, choluria, myalgia, hyperchromic plaques and pruritic lesions. She mentioned recent use of allopurinol, paracetamol and nimesulide, showing significant and spontaneous improvement after discontinuation of medications. The extension of time of exposure to the offending drug causes a longer period of hospitalization and risk of mortality. In addition, the restricted data on DRESS Syndrome poses challenges to its diagnosis. Therefore, this study seeks to highlight the importance of early clinical diagnosis, suspension of the offending drug and the institution of appropriate therapy for a favorable prognosis

ABSTRACT

La evidencia de epidemias e infecciones se manifestó en las Américas -destacando Panamá entre los países afectados-, África y otros lugares. En el año 2016 la Organización Mundial de la Salud (OMS) declaró una emergencia internacional por la presencia de casos de microcefalia y otros trastornos neurológicos en algunas áreas afectadas por el virus Zika. Actualmente se han notificado infecciones por este virus transmitidas por mosquitos en un total de 86 países y territorios. El presente artículo tiene como objetivo estimar la prevalencia e identificar los factores de riesgo del virus Zika en embarazadas de Panamá, como grupo vulnerable ante esta afección. Si la infección por el virus del Zika es mayormente leve en adultos, en las gestantes se deben temer riesgos fetales graves en los casos de infección en el primer trimestre del embarazo. Sin embargo, todavía no hay suficientes investigaciones que aporten datos científicos para conocer el alcance de este riesgo y las consecuencias precisas de una infección fetal(AU)


The evidence of epidemics and infections was manifested in the Americas -Panama standing out among the affected countries-, Africa and other places. In 2016, the world Health Organization (WHO) declared an international emergency due to the presence of cases of microcephaly and other neurological disorders in some areas affected by the Zika virus. Mosquito-borne infections with this virus have now been reported from a total of 86 countries and territories. The objective of this article is to estimate the prevalence and identify the risk factors of the Zika virus in pregnant women in Panama, as a vulnerable group to this disease. If Zika virus infection is mostly mild in adults, serious fetal risks should be feared in pregnant women in cases of infection in the first trimester of pregnancy. However, there is still not enough research that provides scientific data to know the extent of this risk and the precise consequences of a fetal infection(AU)

ABSTRACT

Ethnicity might be associated with treatment outcomes in advanced prostate cancer. This study aimed to evaluate the efficacy and safety of androgen deprivation therapy (ADT) combined with apalutamide in East Asians with metastatic castration-sensitive prostate cancer (mCSPC). The original phase 3 Targeted Investigational Treatment Analysis of Novel Anti-androgen (TITAN) trial was conducted at 260 sites in 23 countries. This subgroup analysis included patients enrolled in 62 participating centers in China, Japan, and Korea. Radiographic progression-free survival (PFS), time to prostate-specific antigen (PSA) progression, and PSA changes from baseline were compared between groups in the East Asian population. The intent-to-treat East Asian population included 111 and 110 participants in the apalutamide and placebo groups, respectively. The 24-month radiographic PFS rates were 76.1% and 52.3% in the apalutamide and placebo groups, respectively (apalutamide vs placebo: hazard ratio [HR] = 0.506; 95% confidence interval [CI], 0.302-0.849; P = 0.009). Median time to PSA progression was more favorable with apalutamide than placebo (HR = 0.210; 95% CI, 0.124-0.357; P < 0.001). Median maximum percentages of PSA decline from baseline were 99.0% and 73.9% in the apalutamide and placebo groups, respectively. The most common adverse event (AE) was rash in the apalutamide group, with a higher rate than that in the placebo group (37.3% vs 9.1%). The most common grade 3 or 4 AEs were rash (12 [10.9%]) and hypertension (12 [10.9%]) for apalutamide. The efficacy and safety of apalutamide in the East Asian subgroup of the TITAN trial are consistent with the global results.

ABSTRACT

BACKGROUND@#Epidermal growth factor receptor (EGFR) and cellular-mesenchymal to epithelial transition factor (c-Met) are widely expressed on cancer cells. There is a synergistic effect of EGFR and HGF/c-Met pathways on proliferation, downstream activation of signal transduction and an additive effect. Studies show that combination of both signaling pathways could potentially be targeted in a synergistic fashion. Amivantamab, a bispecific monoclonal antibody targeting EGFR and c-Met, yielded robust and durable responses in a variety of clinicals trials. However, few researches have reported its efficacy in Chinese non-small cell lung cancer (NSCLC) patients. This study was conducted to evaluate the effectiveness and tolerance of Amivantamab in NSCLC patients with EGFR/MET gene abnormalities at Peking University Cancer Hospital.@*METHODS@#The study enrolled NSCLC patients who received Amivantamab in our hospital between August 2020 and December 2021, and analyzed the response, survival, and treatment-related adverse events.@*RESULTS@#Fifteen patients were enrolled in this research, and six of them received Amivantamab treatment and the other nine patients received Amivantamab plus Lazertinib treatment. The rates of partial response (PR), stable disease (SD), and progressive disease (PD) were 46.7% (7/15), 46.7% (7/15) and 6.7% (1/15), respectively. The overall response rate (ORR) and disease control rate (DCR) were 28.6% (2/7) and 100.0% (7/7) in seven patients with EGFR exon 20 insertion, respectively. The ORR and DCR were 40.0% (2/5) and 100.0% (5/5) in five post-osimertinib EGFR-mutant patients, respectively. After a median follow-up of 8.7 months, the median progression-free survival and overall survival were not reached. The most common treatment-related adverse events were rash (86.7%), paronychia (80.0%), and infusion-related reactions (60.0%), and most of them were graded as 1 to 2. Grade 3 to 4 adverse events included rash (33.3%), alanine aminotransferase elevation (13.3%), gamma-glutamyl transpeptidase elevation (13.3%), peripheral edema (6.7%), thromboembolism (6.7%), interstitial lung disease (6.7%), and thrombocytopenia (6.7%).@*CONCLUSIONS@#Amivantamab was effective in Chinese NSCLC patients with EGFR exon 20 insertion and post-Osimertinib EGFR-mutant patients, similar to the results of clinical trials conducted in western countries. Amivantamab was well tolerated and emphases should be put on adverse events such as rash, paronychia, and infusion-related reactions.

ABSTRACT

The mutation rate of anaplastic lymphoma kinase (ALK) in patients with non-small cell lung cancer is 3% to 7%. Due to its low mutation rate and better long-term survival compared with epidermal growth factor receptor-positive non-small cell lung cancer patients, therefore, it's called "diamond mutation". At present, there are three generations of ALK tyrosine kinase inhibitor (TKI) drugs in the world. The first-generation ALK-TKI drug approved in China is crizotinib, and the second-generation drugs are alectinib, ceritinib and ensartinib. Among them, ensartinib is an ALK-TKI domestically developed, and its efficacy is similar to that of alectinib. The main adverse event is transient rash, and compliance to ensartinib is better from the perspective of long-term survival of patients. The manifestation of rash caused by ensartinib is different from that of other ALK-TKI drugs. In order to facilitate clinical application and provide patients with more treatment options, under the guidance of the Committee of Cancer Rehabilitation and Palliative Care of China Anti-Cancer Association, this article collects and summarizes the common adverse reactions of ensartinib. Based on the clinical practice, a clear adverse classification and specific treatment plan are formulated, in order to provide a corresponding reference for clinicians to make more comprehensive clinical decisions.

ABSTRACT

Abstract Eruptive disseminated Spitz nevi is a rare clinical presentation that features an abrupt widespread eruption of Spitz nevi. Spontaneous regression of these nevi has been rarely reported in previous literature. The authors of the present study report the case of a 30-year-old man who presented eruptive disseminated Spitz nevi that appeared within a week and started regression in the following years.
