  • 文章类型: Journal Article
    背景:这项研究使用2020年的全国住院患者样本(NIS)数据调查了COVID-19对镰状细胞危象(SCC)患者的影响。方法:采用国际疾病分类(ICD-10)代码进行回顾性队列分析,以识别主要诊断为镰状细胞危象的成年人。检查的主要结果是住院死亡率,而评估的次要结局包括发病率,住院时间,和资源利用。用STATA进行分析。使用多变量逻辑和线性回归分析来调整混杂变量。结果:在66,415例确诊为SCC的成人患者中,875人被确诊为COVID-19感染。患有COVID-19的SCC患者的未调整死亡率(2.28%)高于没有COVID-19的患者(0.33%),调整后的比值比(aOR)为8.49(p=0.001)。他们还显示发生急性呼吸衰竭(aOR=2.37,p=0.003)和需要透析的急性肾损伤(aOR=8.66,p=0.034)的几率增加。此外,这些患者的住院时间较长,调整后平均为3.30天(p<0.001),住院费用较高,调整后平均为35,578美元(p=0.005).结论:患有COVID-19的SCC患者死亡率较高,发病率指标增加,住院时间更长,和巨大的经济负担。
    Background: This study investigated the impact of COVID-19 on patients with sickle cell crisis (SCC) using National Inpatient Sample (NIS) data for the year 2020. Methods: A retrospective cohort analysis was conducted utilizing International Classification of Diseases (ICD-10) codes to identify adults who were admitted with a principal diagnosis of sickle cell crisis. The primary outcomes examined were inpatient mortality, while the secondary outcomes assessed included morbidity, hospital length of stay, and resource utilization. Analyses were conducted with STATA. Multivariate logistic and linear regression analyses were used to adjust for confounding variables. Results: Of 66,415 adult patients with a primary SCC diagnosis, 875 were identified with a secondary diagnosis of COVID-19 infection. Unadjusted mortality rate was higher for SCC patients with COVID-19 (2.28%) compared to those without (0.33%), with an adjusted odds ratio (aOR) of 8.49 (p = 0.001). They also showed increased odds of developing acute respiratory failure (aOR = 2.37, p = 0.003) and acute kidney injury requiring dialysis (aOR = 8.66, p = 0.034). Additionally, these patients had longer hospital stays by an adjusted mean of 3.30 days (p < 0.001) and incurred higher hospitalization charges by an adjusted mean of USD 35,578 (p = 0.005). Conclusions: The SCC patients with COVID-19 presented higher mortality rates, increased morbidity indicators, longer hospital stays, and substantial economic burdens.

    简介镰状细胞性贫血(SCA),严重的血液病,其特征是存在镰刀形红细胞,阻塞毛细血管并限制血液流动。这种病理生理学不仅会促进全身并发症,还会影响心脏功能。心脏并发症是SCA患者死亡的主要原因,然而,与疾病严重程度相关的具体心电图(ECG)变化尚不完全清楚.这项横断面研究旨在探索患有SCA的成年人的ECG异常,并将这些发现与疾病严重程度相关联。方法进行为期18个月的观察性横断面研究,从2022年1月到2023年6月,在全印度医学科学研究所镰状细胞OPD的140名SCA患者中,雷普尔,雷普尔,印度。纳入经高效液相色谱法筛选的稳态SCA(HbS>50%)患者。一段历史,体检,全血细胞计数,对所有病例进行心电图检查。使用Adegoke和Kuti严重程度评分计算疾病严重程度评分,并研究了它们与各种ECG变化的关联。卡方检验(Fisher精确检验,在适用的情况下)用于比较比例。使用Pearson相关系数或Spearmanrho进行相关性。结果140例患者中,研究参与者的平均年龄为26±6岁.超过一半的病例(80;57%)属于18-27岁年龄段,男女比例为4:3。共有99名(70.7%)参与者患有轻度疾病,41例(29.3%)患有中度疾病。轻度疾病患者的QT间期明显高于中度疾病患者(p值:<0.01)。与轻度疾病相比,中度疾病患者的QTc离散度和QTc间期延长明显更高(p值分别<0.01、0.04)。窦性心动过速和右心室肥厚伴肺心病中度患者明显增高(p<0.01)。QTc离散度之间呈显著正相关,P波色散,和严重程度(r:0.19,0.17;p值:0.02,0.04,分别)。结论随着病情的加重,所研究的ECG变化具有较高的分布和意义.ECG是一种容易且广泛获得的研究,可用于筛查所有SCA患者,以早期识别各种潜在的心脏并发症。
    Introduction Sickle cell anemia (SCA), a severe hematological disorder, is characterized by the presence of sickle-shaped erythrocytes that obstruct capillaries and restrict blood flow. This pathophysiology not only promotes systemic complications but may also influence cardiac function. Cardiac complications are a leading cause of mortality in SCA patients, yet the specific electrocardiographic (ECG) changes associated with disease severity are not thoroughly understood. This cross-sectional study aimed to explore ECG abnormalities in adults with SCA and correlate these findings with disease severity. Methods An observational cross-sectional study was conducted over 18 months, from January 2022 to June 2023, among 140 SCA patients at the Sickle Cell OPD of All India Institute of Medical Sciences, Raipur, Raipur, India. Steady-state SCA (HbS >50%) patients screened by high-performance liquid chromatography were enrolled. A history, physical examination, complete blood count, and ECG were done for all cases. The disease severity score was calculated using the Adegoke and Kuti severity scores, and their association with various ECG changes was studied. The chi-square test (Fisher\'s exact test, wherever applicable) was used for comparing the proportion. The correlation was done using the Pearson correlation coefficient or Spearman\'s rho. Results Out of 140 patients, the mean age of the study participants was 26 ± 6 years. More than half of the cases (80; 57%) fall under the 18-27 age group, with a male-to-female ratio of 4:3. A total of 99 (70.7%) of the participants had mild disease, and 41 (29.3%) had moderate disease. The QT interval was significantly higher among patients with mild disease compared to those with moderate disease (p-value: <0.01). QTc dispersion and prolonged QTc interval were significantly higher among patients with moderate disease compared to mild disease (p-value <0.01, 0.04, respectively). Sinus tachycardia and right ventricular hypertrophy with p-pulmonale were significantly higher in moderate severity (p < 0.01). A significant positive correlation was observed between QTc dispersion, P-wave dispersion, and severity (r: 0.19, 0.17; p-value: 0.02, 0.04, respectively). Conclusion As the disease severity progressed, the ECG changes studied had a higher distribution and significance. ECG is a readily and widely accessible investigation that can be used to screen all SCA patients for early recognition of various underlying cardiac complications.

    众所周知,一种称为镰状细胞病(SCD)的遗传性血液疾病是一种基因的结果。已经确定了与SCD患者的实验室和临床病史相关的许多血液和尿液生物标志物。SCD有许多与之相关的相互作用途径,已通过生物标志物鉴定。这些机制包括一些例子,如内皮血管舒张反应,高凝状态,溶血,炎症,氧化应激,血管功能障碍,和再灌注损伤等等。为了有效地管理SCD,必须建立一组经过验证的血液和尿液生物标志物。尽管它是单基因遗传,SCD表型的复杂性阻碍了其治疗的进展.然而,临床生物技术取得了重大进展,为潜在的突破铺平道路。在SCD中,必须建立一组经过验证的血液和尿液生物标志物,however.尽管单基因遗传,SCD表型的复杂性阻碍了其管理的进展。除了少数例外,通过流行病学调查发现了疾病严重程度的临床生物标志物;然而,尚未将这些生物标志物系统地整合到临床治疗算法中。此外,镰状细胞危机,SCD的主要急性后果,用现在使用的生物标志物很难诊断。这些诊断限制的后果是缺乏适当的护理和临床研究的适当结果措施。随着分子和成像诊断的最新进展,SCD定制治疗的新篇章已经开始。精准医学的策略尤其重要,因为分子疗法已经触手可及。本研究综述了生化指标与SCD临床表现和亚表型鉴定相关的意义。
    It is known that an inherited blood condition called sickle cell disease (SCD) is a result of one gene. A number of blood and urine biomarkers have been determined in association with lab and clinical history for SCD patients. SCD has numerous interacting pathways associated with it, which have been identified by biomarkers. These mechanisms consist of some examples, such as endothelial vasodilation response, hypercoagulability, hemolysis, inflammation, oxidative stress, vascular dysfunction, and reperfusion injury among others. To effectively manage SCD, a comprehensive panel of validated blood and urine biomarkers must be established. Despite its monogenic inheritance, the complex nature of the SCD phenotype has impeded progress in its treatment. However, significant strides have been made in clinical biotechnology, paving the way for potential breakthroughs. In SCD, a panel of verified blood and urine biomarkers must be established, however. Despite monogenic inheritance, the great complexity of the SCD phenotype has hindered progress in its management. With few exceptions, clinical biomarkers of illness severity have been found through epidemiological investigations; nevertheless, systematic integration of these biomarkers into clinical treatment algorithms has not occurred. Furthermore, sickle cell crisis, the primary acute consequence of SCD, has been difficult to diagnose with the biomarkers now in use. Inadequate care and a lack of appropriate outcome measures for clinical research are the consequences of these diagnostic constraints. A new chapter in SCD customized treatment has begun with recent advancements in molecular and imaging diagnostics. Strategies in precision medicine are especially relevant now that molecular therapies are within reach. The significance of biochemical indicators linked to clinical manifestation and sub-phenotype identification in SCD is reviewed in this research.

    急性疼痛性血管闭塞性危象(VOC)是镰状细胞病(SCD)的常见表现,导致急诊室就诊。招生,发病率,死亡率,以及对生活质量的负面影响。在通常用于控制病情的各种治疗方法中,静脉(IV)水合作用也经常用于急诊和住院设置.虽然有助于克服脱水,静脉水合通常会导致不良后果,如液体超负荷,肺水肿,停留时间增加,转移到重症监护室,新的需氧量,等。进行小规模回顾性研究以研究静脉水化的结果,但未能最终证明其益处以及静脉输液的选择。静脉补液率,等。我们进行这篇综述,试图总结关于静脉水化在镰状细胞危象中的作用和效用以及报告的不良结果的现有证据。
    Acute painful vaso-occlusive crisis (VOC) is the common presentation of sickle cell disease (SCD) leading to emergency room visits, admissions, morbidity, mortality, and negative impacts on quality of life. Among various treatment approaches commonly employed to manage the condition, intravenous (IV) hydration is also frequently used in emergency and inpatient settings. Although helpful to overcome dehydration, IV hydration often leads to adverse outcomes like fluid overload, pulmonary edema, increased length of stay, transfer to intensive care unit, new oxygen requirement, etc. Small-scale retrospective studies are conducted to study the outcomes of IV hydration but have failed to conclusively demonstrate its benefits as well as choice of IV fluids, rate of IV fluid replacement, etc. We conduct this review as an attempt to summarize the available evidence on the role and utility of IV hydration in sickle cell crises along with reported adverse outcomes.

    我们介绍了一名19岁的男性,有镰状细胞性贫血病史,他因下肢疼痛恶化而住院。鉴于他的急性表现和复发性疼痛危机的历史,他因治疗疑似急性疼痛危机而入院。然而,由于持续的疼痛,获得的影像学检查显示了对其症状原因的不同诊断。左小腿MRI提示胫骨近端6.6×1.6×2.2cm内T1、T2高信号不均一,周边边缘厚不规则强化,周围有骨膜反应及软组织水肿。关于骨髓炎和Brodie脓肿的发展。患者接受了胫骨冲洗和清创术,并放置了万古霉素和妥布霉素珠。围手术期,软组织内没有发现有脓液,组织培养物上没有生物生长。患者的疼痛得到改善,他出院回家,计划完成六周的静脉注射抗生素。这种情况表明需要区分Brodie的脓肿和镰状细胞危象。临床医生也应该意识到,患有病态细胞疾病的患者容易出现Brodie的脓肿,这应该是缓解骨痛症状的区别。
    We present the case of a 19-year-old male with a history of sickle cell anemia who presented to the hospital with worsening lower extremity pain. Given his acute presentation and history of recurrent pain crises, he was admitted to the hospital for management of a suspected acute pain crisis. However, due to continued pain, imaging was obtained which revealed a different diagnosis for the cause of his symptoms. MRI of the left lower leg revealed heterogenous T1 and T2 hyperintense signals within the proximal tibial diaphysis measuring 6.6 × 1.6 × 2.2 cm with a thick rim of peripheral irregular enhancement with surrounding periosteal reaction and soft tissue edema, concerning for osteomyelitis and developing Brodie\'s abscess. The patient underwent tibia irrigation and debridement with the placement of vancomycin and tobramycin beads. Perioperatively, no purulence was noted within the soft tissues, and no organisms were grown on tissue cultures. The patient\'s pain improved and he was discharged home with a plan to complete six weeks of intravenous antibiotics. This case represents the need to differentiate Brodie\'s abscess from a sickle cell crisis. Clinicians should also be aware that patients with sick cell disease are prone to Brodie\'s abscess and it should be a differential for symptoms of relenting bone pain.

    红细胞交换(RCE)通过降低血液粘度和改善携氧能力来帮助治疗镰状细胞性贫血(SCA)的并发症。我们介绍了使用自动RCE管理的镰状细胞危象(SCC)病例,并回顾了文献以评估该疗法在印度的利用率和临床效率。一位19岁的绅士被诊断为SCA,并表现为急性胸部综合症。血红蛋白(Hb)为8.8g%,血细胞比容(HCT)为24%,HbS为90%。由于常规治疗的症状恶化,患者接受了两个自动RCE程序。患者的临床状况有所改善,术后HbS降至16%,HCT保持在21%。回顾了在印度进行的有关SCA中自动RCE的文章,并根据搜索策略对四篇文章进行了分析。所有纳入的文章都认为自动RCE是治疗SCA并发症的有效方法。在印度,常见的适应症是接受手术作为预防措施的SCA患者。自动化RCEs有望作为指示镰状细胞并发症的急性治疗方法。这种疗法在印度的情况下没有得到充分利用,尤其是SCC患者。
    Red cell exchanges (RCE) help in the treatment of complications of sickle cell anemia (SCA) by reducing the viscosity of blood and improving the oxygen-carrying capacity. We present a case of sickle cell crisis (SCC) managed with automated RCE and also reviewed the literature to assess the utilization and clinical efficiency of this therapy in India. A 19-year-old gentleman diagnosed with SCA presented with acute chest syndrome. Hemoglobin (Hb) was 8.8 g%, hematocrit (HCT) was 24%, and HbS was 90%. As there was worsening of symptoms with conventional management, the patient underwent two procedures of automated RCE. The clinical condition of the patient was improved, HbS was reduced to 16% and HCT was remained at 21% postprocedure. Articles on automated RCE in SCA conducted in India were reviewed and four articles were analyzed based on the search strategy. All the included articles concluded automated RCE as an effective procedure for complications of SCA. Common indication in India was SCA patients undergoing surgery as a prophylactic measure. Automated RCEs are promising as an acute treatment for indicated sickle cell complications. This therapy is underutilized in the Indian scenario, especially in patients with SCC.

    镰状细胞病(SCD)是世界上最常见的遗传性血红蛋白病。它导致死后计算机断层扫描(PMCT)的特征性急性和慢性发现,宏观和微观检查。虽然诊断成像和宏观特征本身并不针对SCD,当再加上镰状红细胞等微观特征和慢性静脉充血的证据(即,Gamna-Gandy尸体),这些线索有助于提醒法医病理学家注意SCD的存在.尽管这种疾病的流行和上面提到的一系列发现,SCD在法医病理学文献中并不经常被探索。此病例显示了PMCT上SCD的经典急性和慢性特征,宏观和微观检查。它探讨了导致SCD患者突然和意外死亡的病理生理学以及死亡原因归因的可能陷阱。
    Sickle cell disease (SCD) is the most common hereditary hemoglobinopathy worldwide. It results in characteristic acute and chronic findings on postmortem computed tomography (PMCT), macroscopic and microscopic examinations. While the diagnostic imaging and macroscopic features are not specific for SCD on their own, when coupled with microscopic features such as sickled erythrocytes and evidence of chronic venous congestion (i.e., Gamna-Gandy bodies), these clues can help alert forensic pathologists to the presence of SCD. Despite the prevalence of the disease and the constellation of findings alluded to above, SCD is not often explored in forensic pathology literature. This case demonstrates classic acute and chronic features of SCD on PMCT, macroscopic and microscopic examinations. It explores the pathophysiology leading to sudden and unexpected death in a person with SCD and possible pitfalls in attribution of cause of death.

    镰状细胞病是一种与多器官损伤相关的遗传性常染色体隐性血红蛋白病。这种单基因疾病涉及一个DNA碱基对的改变,生产HBS。镰状细胞在毛细血管中脱氧时形成。由此产生的红细胞淤滞导致缺血和疼痛,以及急性和慢性器官损伤。到牙科诊所就诊的SCD患者需要仔细检查,以排除任何当前的感染,神经缺陷,在制定牙科治疗计划之前,或其他器官受累,以避免长时间和复杂的程序。早期干预和牙科焦虑管理是SCD患者牙科治疗的关键。
    Sickle Cell Disease is an inherited autosomal recessive hemoglobinopathy associated with multiorgan damage. This single gene disorder involves one DNA base pair alteration, producing HbS. The sickle-shaped cells form when deoxygenated in the capillaries. The resulting RBC stasis leads to ischemia and pain, and acute and chronic organ damage. Patients with SCD presenting to a dental office need careful examination to rule out any current infections, neurologic deficits, or other organ involvement before formulating a dental treatment plan to avoid prolonged and complicated procedures. Early intervention and dental anxiety management are key to the dental treatment of patients with SCD.
