Abstract
Data on acute chest syndrome (ACS) in adult sickle cell disease patients are scarce. In this study, we describe 105 consecutive ACS episodes in 81 adult patients during a 32-month period and compare the characteristics as a function of the time to onset after hospital admission for a vaso-occlusive crisis (VOC), that is early-onset episodes (time to onset ≤24 h, 42%) versus secondary episodes (>24 h, 58%; median [interquartile range] time to onset: 2 [2-3] days). The median age was 27 [22-34] years, 89% of the patients had an S/S or S/β0 -thalassaemia genotype; 81% of the patients had a history of ACS (median: 3 [2-5] per patient), only 61% were taking a disease-modifying treatment at the time of the ACS. Fever and chest pain were noted in respectively 54% and 73% of the episodes. Crackles (64%) and bronchial breathing (32%) were the main abnormal auscultatory findings. A positive microbiological test was found for 20% of episodes. Fifty percent of the episodes required a blood transfusion; ICU transfer and mortality rates were respectively 29% and 1%. Secondary and early-onset forms of ACS did not differ significantly. Disease-modifying treatments should be revaluated after each ACS episode because the recurrence rate is high.

Abstract
Sickle cell disease is a frequent genetic condition, due to a mutation of the β-globin gene, leading to the production of an abnormal S hemoglobin and characterized by multiple vaso-occlusive events. The acute chest syndrome is a severe complication associated with a significant disability and mortality. It is defined by the association of one or more clinical respiratory manifestations and a new infiltrate on lung imaging. Its pathophysiology is complex and implies vaso-occlusive phenomena (pulmonary vascular thrombosis, fat embolism), infection, and alveolar hypoventilation. S/S or S/β0-thalassemia genotype, a history of vaso-occlusive crisis or acute chest syndrome, a low F hemoglobin level (<5%), a high steady-state hemoglobin level (> 10 g/dL), or a high steady-state leukocytosis (>10 G/L) are the main risk factors. Febrile chest pain, dyspnea, sometimes cough with expectorations are its main clinical manifestations, and bi-basal crackles are found at auscultation. Inferior alveolar opacities with or without pleural effusions are identified on chest X-ray or CT-scan. Management of the acute chest syndrome should be prompt and implies, besides the recognition of severity signs, a multimodal analgesia, oxygen supplementation, sometimes a parenteral antibiotic treatment and the frequent use of blood transfusions especially in the most severe cases. Prevention is important and includes a regular monitoring of hospitalized patients and the use of incentive spirometry.

Abstract
Acute chest syndrome (ACS) is the leading cause of death among people with sickle cell disease. ACS is clinically defined and diagnosed by the presence of a new pulmonary infiltrate on chest imaging with accompanying fever and respiratory symptoms like hypoxia, tachypnea, and shortness of breath. However, the characteristic chest x-ray (CXR) findings necessary for a clinical diagnosis of ACS can be difficult to detect, as is determining which patient needs a CXR. This makes early detection difficult; but it is critical in order to limit ACS severity and subsequent fatalities. This research project looks to apply percussion and auscultation techniques that can provide an immediate diagnosis of acute pulmonary conditions by using an automated standard percussive input and electronic auscultation for computational analysis of the measured signal. Measurements on sickle cell patients having ACS, vaso-occlusive crisis (VOC), and regular clinic visits (healthy) were recorded and analyzed. Average intensity of sound transmission through the chest and lungs was determined in the ACS and healthy subject groups, revealing an average of 10–14 dB decrease in sound intensity in the ACS group compared to the healthy group. A random under-sampling boosted tree classification model identified with 94% accuracy the positive ACS and healthy observations. The analysis also revealed unique measurable changes in a small number of cases clinically classified as complicated VOC, which later developed into ACS. This suggests the developed approach may also have early predictive capability, identifying patients at risk for developing ACS prior to current clinical practice.

Abstract
Sickle cell disease is a debilitating hematologic process that affects the entire body. Disease manifestations in the abdomen most commonly result from vaso-occlusion, hemolysis, or infection due to functional asplenia. Organ specific manifestations include those involving the liver (eg, hepatopathy, iron deposition), gallbladder (eg, stone formation), spleen (eg, infarction, abscess formation, sequestration), kidneys (eg, papillary necrosis, infarction), pancreas (eg, pancreatitis), gastrointestinal tract (eg, infarction), reproductive organs (eg, priapism, testicular atrophy), bone (eg, marrow changes, avascular necrosis), vasculature (eg, vasculopathy), and lung bases (eg, acute chest syndrome, infarction). Imaging provides an important clinical tool for evaluation of acute and chronic disease manifestations and complications. In summary, there are multifold abdominal manifestations of sickle cell disease. Recognition of these sequela helps guide management and improves outcomes. The purpose of this article is to review abdominal manifestations of sickle cell disease and discuss common and rare complications of the disease within the abdomen.

Abstract
BACKGROUND Sickle cell disease is an inherited autosomal recessive blood condition and is one of the most prevalent genetic blood diseases worldwide. Acute chest syndrome is a frequent complication of sickle cell disease, as well as a major cause of morbidity and the greatest single cause of mortality in children with sickle cell disease. Standard treatment may include intravenous hydration, oxygen as treatment for hypoxia, antibiotics to treat the infectious cause and blood transfusions may be given. This is an update of a Cochrane Review first published in 2010 and updated in 2016. OBJECTIVES To assess the effectiveness of blood transfusions, simple and exchange, for treating acute chest syndrome by comparing improvement in symptoms and clinical outcomes against standard care. SEARCH METHODS We searched The Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. Date of the most recent search: 30 May 2019. SELECTION CRITERIA Randomised controlled trials and quasi-randomised controlled trials comparing either simple or exchange transfusion versus standard care (no transfusion) in people with sickle cell disease suffering from acute chest syndrome. DATA COLLECTION AND ANALYSIS Both authors independently selected trials and assessed the risk of bias, no data could be extracted. MAIN RESULTS One trial was eligible for inclusion in the review. While in the multicentre trial 237 people were enrolled (169 SCC, 42 SC, 15 Sβ⁰-thalassaemia, 11Sβ+-thalassaemia); the majority were recruited to an observational arm and only ten participants met the inclusion criteria for randomisation. Of these, four were randomised to the transfusion arm and received a single transfusion of 7 to 13 mL/kg packed red blood cells, and six were randomised to standard care. None of the four participants who received packed red blood cells developed acute chest syndrome, while 33% (two participants) developed acute chest syndrome in standard care arm. No data for any pre-defined outcomes were available. AUTHORS' CONCLUSIONS We found only one very small randomised controlled trial; this is not enough to make any reliable conclusion to support the use of blood transfusion. Whilst there appears to be some indication that chronic blood transfusion may play a roll in reducing the incidence of acute chest syndrome in people with sickle cell disease and albeit offering transfusions may be a widely accepted clinical practice, there is currently no reliable evidence to support or refute the perceived benefits of these as treatment options; very limited information about any of the potential harms associated with these interventions or indeed guidance that can be used to aid clinical decision making. Clinicians should therefore base any treatment decisions on a combination of; their clinical experience, individual circumstances and the unique characteristics and preferences of adequately informed people with sickle cell disease who are suffering with acute chest syndrome. This review highlights the need of further high quality research to provide reliable evidence for the effectiveness of these interventions for the relief of the symptoms of acute chest syndrome in people with sickle cell disease.

Abstract
BACKGROUND The clinical presentation of acute chest syndrome is similar whether due to infectious or non-infectious causes, thus antibiotics are usually prescribed to treat all episodes. Many different pathogens, including bacteria, have been implicated as causative agents of acute chest syndrome. There is no standardized approach to antibiotic therapy and treatment is likely to vary from country to country. Thus, there is a need to identify the efficacy and safety of different antibiotic treatment approaches for people with sickle cell disease suffering from acute chest syndrome. This is an update of a Cochrane Review first published in 2007, and most recently updated in 2015. OBJECTIVES To determine whether an empirical antibiotic treatment approach (used alone or in combination):1. is effective for acute chest syndrome compared to placebo or standard treatment;2. is safe for acute chest syndrome compared to placebo or standard treatment;Further objectives are to determine whether there are important variations in efficacy and safety:3. for different treatment regimens,4. by participant age, or geographical location of the clinical trials. SEARCH METHODS We searched The Group's Haemoglobinopathies Trials Register, which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. We also searched the LILACS database (1982 to 23 October 2017), African Index Medicus (1982 to 23 October 2017) and trial registries (23 October 2017).Date of most recent search of the Haemoglobinopathies Trials Register: 10 July 2019. SELECTION CRITERIA We searched for published or unpublished randomised controlled trials. DATA COLLECTION AND ANALYSIS Each author intended to independently extract data and assess trial quality by standard Cochrane methodologies, but no eligible randomised controlled trials were identified. MAIN RESULTS For this update, we were unable to find any randomised controlled trials on antibiotic treatment approaches for acute chest syndrome in people with sickle cell disease. AUTHORS' CONCLUSIONS This update was unable to identify randomised controlled trials on efficacy and safety of the antibiotic treatment approaches for people with sickle cell disease suffering from acute chest syndrome. While randomised controlled trials are needed to establish the optimum antibiotic treatment for this condition, we do not envisage further trials of this intervention will be conducted, and hence the review will no longer be regularly updated.

Abstract
ACS (ACS) is a serious complication of sickle cell anaemia (SCA). We set out to describe the burden, presentation and organisms associated with ACS amongst children with SCA attending Mulago Hospital, Kampala, Uganda. In a cross-sectional study, 256 children with SCA and fever attending Mulago Hospital were recruited. Chest X-rays, blood cultures, complete blood count and sputum induction were performed. Sputum samples were investigated by Ziehl-Nielsen staining, culture and DNA polymerase chain reaction (PCR) for Chlamydia pneumoniae. Of the 256 children, 22·7% had ACS. Clinical and laboratory findings were not significantly different between children with ACS and those without, besides cough and abnormal signs on auscultation. Among the 83 sputum cultures Streptococcus pneumoniae (12%) and Moraxella spp (8%), were the commonest. Of the 59 sputa examined with DNA PCR, 59·3% were positive for Chlamydia pneumoniae. Mycobacterium tuberculosis was isolated in 6/83 sputa. These results show that one in 5 SCA febrile children had ACS. There were no clinical and laboratory characteristics of ACS, but cough and abnormalities on auscultation were associated with ACS. The high prevalence of Chlamydia pneumoniae in children with ACS in this setting warrants the addition of macrolides to treatment, and M. tuberculosis should be differential in sub-Saharan children with ACS.

Abstract
OBJECTIVE Controversy exists regarding which febrile children with sickle cell disease (SCD) should receive a chest x-ray (CXR). Our goal is to provide data informing the decision of which febrile children with SCD presenting to the emergency department (ED) require a CXR to evaluate for acute chest syndrome (ACS). METHODS Retrospective chart review of children ages 3 months to 21 years with SCD presenting to the ED at one of two academic children's hospitals with fever ≥38.5°C between January 1, 2010, and December 31, 2012. Demographic characteristics, respiratory symptoms, and laboratory results were abstracted. The primary outcome was the presence of ACS. Binary recursive partitioning was performed to determine predictive factors for a diagnosis of ACS. RESULTS A total of 185 (10%) of 1,837 febrile ED visits met ACS criteria. The current National Heart, Lung, and Blood Institute (NHLBI) consensus criteria for obtaining a CXR (shortness of breath, tachypnea, cough, or rales) identified 158 (85%) of ACS cases, while avoiding 825 CXRs. Obtaining a CXR in children with NHLBI criteria or chest pain and in children without those symptoms but with a white blood cell (WBC) count ≥18.75 × 109 /L or a history of ACS identified 181 (98%), while avoiding 430 CXRs. CONCLUSION Children with SCD presenting to the ED with fever and shortness of breath, tachypnea, cough, rales, or chest pain should receive a CXR due to high ACS rates. A higher WBC count or history of ACS in a child without one of those symptoms may suggest the need for a CXR. Prospective validation of these criteria is needed.

Abstract
BACKGROUND Even though sickle cell disease has a high prevalence amongst the black race and despite its well known potential of micro infarction, there have been only a few reports regarding the acute myocardial damage during vaso-occlusive crisis. The risk of atrio ventricular block during these crises has never been described in a large survey. PATIENTS AND RESULTS Ten patients (six men and four women, mean age 39 years old) were hospitalized for an acute atrio ventricular block. The patients were all African or Caribbean natives. Three patients were found with a heterozygous phenotype for hemoglobin S (sickle trait) and seven were found with a homozygous phenotype. The most common symptoms were asthenia (10 cases), shortness of breath (8 cases) and acute coronary syndrome (1 case) (syncope was not reported). Four patients had a second degree atrio ventricular block and six patients had third degree block. The treatment involved bed rest, intravenous hydration, and pain relief with opiates. All the cases of atrio ventricular block were only transitory and none of the patients underwent a pacemaker implantation. CONCLUSION This report is the largest survey regarding transitory acute atrio ventricular block in patients with sickle cell disease. A local ischemic event affecting the AV node and Hiss bundle area can explain the conduction abnormalities. Sickle cell disease must be ruled out in black patients with an AV block.

Abstract
The predominant pathophysiological feature of homozygous sickle cell anemia (SCA) is the vaso-occlusion. Vaso-occlusion can be associated with painful crises, which are the primary reason for those patients to seek medical care. Vaso-occlusion is responsible for the acute chest syndrome (ACS) with large morbidity and mortality or more rarely (and especially in adults) for priapism and acute neurological events (strokes). A 10-year-old boy with homozygous SCA was admitted to the Pediatric Emergencies with painful vaso-occlusive crisis and fever. Initially he had normal chest X-ray but, after 24-hour-hospitalization, he developed ACS with new chest X-ray findings. He was treated with broad spectrum antibiotics, blood transfusions and bronchodilators and after a six-day treatment, he was significantly improved. The patient was discharged 13 days later with no other therapy at home. The possibility of ACS development should be still considered, even when a known patient with SCA presents a painful vaso-occlusive crisis with an initial normal chest X-ray. Therefore, repeated clinical examination is required and possible changes in the clinical status could indicate the necessity of a new radiographic examination. In this way, early ACS could be recognized and the catastrophic consequences due to this syndrome could be avoided.

Abstract
AIMS To describe the epidemiology and clinical profile of acute chest syndrome (ACS) in Omani Arab children. METHODS Prospective, clinical study of consecutive episodes of ACS in patients with sickle cell disease (SCD) seen at Nizwa Regional Referral Hospital, Oman between June 2001 and May 2006. RESULTS Of 240 patients registered with SCD, 52 (22%) developed 55 episodes of ACS. There were 31 (59.6%) males and ages ranged between 14 months and 12 years [median (SD) 6.5 (2.49) years]; ACS occurred fairly evenly in those aged between 2 and 10 years. Ten (18%) episodes were mild, 51% moderate and 31% severe. In general, there was no relationship between severity of SCD and the incidence of ACS, but in 71% of cases a vaso-occlusive crisis (VOC) preceded the episodes. Other probable precipitating factors were acute upper respiratory tract infections (in 29% of cases) and use of morphine (26%). The distribution of ACS during the year was bimodal, peaking in May and September and at its lowest in June and December/January. Fever, cough, chest pain, tachypnoea, reduced breath sounds, crackles and chest radiograph opacities were the main manifestations. However, respiratory physical signs were absent in 36% of episodes. CONCLUSIONS ACS is common in SCD. Irrespective of SCD severity, all patients appeared to be at risk of the syndrome, but the risk is increased by VOCs. Prevention of VOCs, prompt and effective treatment of respiratory infections and caution in the use of morphine during a VOC should reduce the incidence of ACS.

Abstract
OBJECTIVES The objectives of this study were to determine the incidence of acute chest syndrome (ACS) in children with sickle cell disease (SCD) presenting with fever before and after the introduction of the 7-valent pneumococcal conjugate vaccine (PCV7) and to determine clinical factors associated with ACS for a febrile child with SCD. METHODS A retrospective chart review was undertaken for children with SCD from 1993 to 2009 in a single, urban, tertiary-care pediatric center. Clinical and laboratory data for each febrile event for each child with SCD were recorded. We compared incidence of ACS for the 3 PCV7 eras: pre-PCV7, inter-PCV7, and post-PCV7. Univariate analysis and stepwise logistic regression were used to identify clinical factors most associated with ACS in the post-PCV7 era. RESULTS Of 2504 febrile events in 466 children with SCD, we found 492 diagnoses of ACS. The incidence of ACS cumulatively decreased over time from 27.0% to 17.4% among febrile children with SCD (P < 0.001), although no change was seen in children younger than 2 years (P = 0.89). Independent predictors of ACS in the post-PCV7 era include history of previous ACS, upper respiratory tract infection symptoms, noncompliance to penicillin, male sex, hypoxemia, an absolute neutrophil count greater than 9 × 10/L, and hemoglobin less than 8.6 g/dL. CONCLUSIONS The incidence of ACS has decreased over time in febrile children with SCD. No effect was seen in those 2 years or younger. Children with SCD presenting with a fever had higher odds of developing ACS when accompanied by certain clinical, demographic, and laboratory features.

Abstract
A prospective cohort study to assess the risk factors for acute chest syndrome (ACS) in individuals with sickle cell disease was carried out in a referral center from Sergipe, Brazil. A total of 168 SS homozygotic individuals (ages between 12 wk and 26 y) were followed for 12 months. There were 134 admissions of 81 patients. There were 50 events of ACS, which was the second most frequent cause of hospital admission (after pain crisis). One patient died of ischemic stroke during follow up. In bivariate analysis, the following variables showed statistically significant associations with the occurrence of ACS: age less than 5 years, living in rural area, history of previous hospital admission; white blood cell count greater than 10,000/dL; hemoglobin concentration less than 7 g/dL and oxygen saturation ≤ 95% on admission. After controlling for confounding in multivariate logistic regression, only a history of previous admission remained as an independent predictor of ACS (relative risk=4.20; 95% confidence interval: 1.79-9.87; P=0.001). Patients with a positive history of hospital admission are under increased risk and should be monitored closely for prevention and early detection of ACS.

Abstract
Children frequently present to a pediatric office or emergency department with the complaint of chest pain. Between 0.3% and 0.6% of visits to a pediatric emergency department are for chest pain. Unlike adult patients with chest pain, most studies have shown that children with chest pain rarely have serious organic pathology. Infrequently, a child with chest pain will present with significant distress and require immediate resuscitation. Most children with chest pain are not in extremis, and for many, the pain is not acute in nature.

Abstract
BACKGROUND Sickle cell disease (SCD) is an inherited autosomal recessive blood condition and is one of the most prevalent genetic blood diseases worldwide. Acute chest syndrome (ACS) is a frequent complication of sickle cell disease, as well as a major cause of morbidity and the greatest single cause of mortality in children with SCD. Standard treatment may include intravenous hydration, oxygen as treatment for hypoxia, antibiotics to treat the infectious cause and blood transfusions may be given. OBJECTIVES To assess the effectiveness of blood transfusions, simple and exchange, for treating ACS by comparing improvement in symptoms and clinical outcomes against standard care. SEARCH STRATEGY We searched The Group's Haemoglobinopathies Trials Register, which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings.Most recent search: 27 March 2009. SELECTION CRITERIA Randomised controlled trials and quasi-randomised controlled trials comparing either simple or exchange transfusion versus standard care (no transfusion) in people with sickle cell disease suffering from acute chest syndrome. DATA COLLECTION AND ANALYSIS No studies were identified for inclusion in the review. MAIN RESULTS No studies were identified for inclusion in the review. AUTHORS' CONCLUSIONS There is currently no reliable evidence to support or refute the effectiveness of blood transfusions as treatment options for acute chest syndrome in people with sickle cell disease. Well-designed, adequately-powered randomised controlled trials are now required to assess the benefits and risks of this form of treatment.

Abstract
BACKGROUND Acute chest syndrome has been defined as a new infiltrate visible on chest radiograph associated with one or more symptoms, such as fever, cough, sputum production, tachypnea, dyspnea, or new-onset hypoxia. Symptoms and complications of this syndrome, whether of infectious or non-infectious origin, vary quite widely in people with sickle cell disease. Lung infection tends to predominate in children, whilst infarction appears more common in adults. However, these are often interrelated and may occur concurrently. The differences in clinical course and severity are suggestive of multiple causes for acute chest syndrome. Successful treatment depends principally on high-quality supportive care. The syndrome and its treatment have been extensively studied, but the response to antibiotics, anticoagulants, and other conventional therapies remains disappointing. The potential of inhaled nitric oxide as a treatment option has more recently provoked considerable interest. Nitric oxide appears to play a major role in both the regulation of vascular muscle tone at the cellular level and in platelet aggregation (clumping). Much of the pathophysiology of sickle cell disease is consistent with a mechanism of nitric oxide depletion and although there has been extensive research on the pathophysiology of acute chest syndrome, the possible therapeutic role of inhaled nitric oxide for acute chest syndrome in sickle cell disease is still to be determined. OBJECTIVES To assess the effectiveness of inhaled nitric oxide for treating acute chest syndrome by comparing improvement in symptoms and clinical outcomes against standard care. SEARCH STRATEGY We searched The Group's Haemoglobinopathies Trials Register, which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. In July 2007 the following clinical trials registers were searched: ClinicalTrials.gov (www.clinicaltrials.gov/); the WHO International Clinical Trials Registry Platform (www.who.int/trialsearch/); Current Controlled Trials (www.controlled-trials.com/) and CLINICALTRIALS.COM (www.clinicaltrials.com/). Most recent search of the Trials Register: November 2007. SELECTION CRITERIA All randomised or quasi-randomised controlled trials of people with sickle cell disease suffering from acute chest syndrome, comparing the use of inhaled nitric oxide to placebo or standard care for any single or multiple treatment and over any time period. DATA COLLECTION AND ANALYSIS No studies identified were eligible for inclusion. MAIN RESULTS No studies identified were eligible for inclusion. AUTHORS' CONCLUSIONS There is a need for well-designed, adequately-powered randomised controlled trial to assess the benefits and risks of this form of treatment as an adjunct to established therapies.

Abstract
BACKGROUND AND OBJECTIVES Genetic studies suggest that the sickle cell mutation has arisen on at least four separate occasions in Africa and as a fifth independent mutation in the Eastern Province of Saudi Arabia or India. The pathophysiology of sickle cell disease (SCD) is essentially similar in these different areas although the frequency and severity of complications may vary between areas. The aim of this study was to evaluate the prevalence and outcome of acute chest syndrome (ACS) in SCD patients from Eastern province of Saudi Arabia in comparison with patients with African haplotypes. MATERIALS AND METHODS This was a retrospective study involving 317 SCD patients who were two years or older, admitted to King Fahad Hospital Hofuf between January-May 2003 for different etiologies. Twenty six patients presented with different causes of ACS; 11 patients presented with different pathologies other than ACS, but had past history of ACS; 280 patients presented with different pathologies and never presented with ACS. Clinical features, CBC, Hb-electrophoresis, G6PD activity, cultures, chest X-ray, arterial oxygen saturation, blood transfusion rates and outcome were studied. Univariate and multiple regression analysis were carried out to evaluate influence on ACS. Comparison between SCD patients with ACS from this study and from Eastern province of Saudi Arabia to patients with African haplotypes were carried out, using data reported in the literature. RESULTS During the period of this study, 37 patients with new or previous episodes of ACS were studied (accounting for 11.67% of admitted SCD patients). Most of the patients with ACS had only one episode, but five patients (13.51%) had had episodes or more. One patient died giving an in-hospital mortality rate of 1/26 (3.85%). Comparison of recurrence of ACS and mortality between SCD patients in Eastern province of Saudi Arabia to that of patients with African haplotype showed that recurrence is significantly lower (P<0.025) in patients from Eastern province compared to patients with African haplotype, mortality also is lower but not statistically significant. CONCLUSION Acute chest syndrome in SCD patients in Eastern province of Saudi Arabia is relatively uncommon, but causes significant morbidity and mortality. Its prevalence and recurrence is low if compared to that of patients with African haplotypes.
