Recognize the clinical signs and symptoms of sickle cell crisis and its associated complications. Considerations Sickle cell disease is common, affecting approximately 1 in every 400 African Americans and 1 in 16,000 Asian Americans. It can affect almost any organ system and has a wide variety of clinical presentations. Acute chest syndrome is the leading cause of death and second leading cause of hospitalization among patients with sickle cell disease. Acute chest syndrome can present primarily or develop after a sickle cell patient is hospitalized for a vasoocclusive crisis. The clinician’s priorities are to differentiate the mild from the life-threatening crises and to treat them. The patient in this case, a 30-year-old woman with known sickle cell disease, has acute onset of chest pain, cough, fever, and subtle findings on the pulmonary examination. Her oxygen saturation is 94% on room air, which is concerning, and should be followed up with an arterial blood gas. Pulmonary embolism, pneumonia, and acute chest syndrome should be considered as possible diagnoses, as individual or concomitant conditions. Acute chest syn- drome is a constellation of symptoms that includes chest pain and tachypnea. It usually presents with some combination of chest pain, fever, hypoxia, and a new pulmonary infiltrate on chest radiography. Therefore, it is prudent to treat these patients with antibiotics, obtain a Gram stain and culture of the sputum, and admit them to the hospital. The treatment for acute chest syndrome is supportive and includes oxygen, intravenous fluid hydration, and analgesia. The most common cause of aplastic crisis appears to be infection, specifically parvovirus. However, in sickle cell disease, hemoglobin S (HbS) results when a valine is substituted for glutamine in the sixth position of the beta chain. Under hypoxic or acidotic conditions, this abnormal hemoglobin polymerizes and sickles, resulting in sludging in the microcirculation. Patients who are heterozygous (sickle cell trait) are generally asymptomatic except under extreme stress (eg, severe dehydra- tion, temperature, or pressure change), but do tend to be more susceptible than the general population to urinary tract infections. Those who have sickle cell disease (homozygous), in contrast, are highly susceptible to vasoocclusion and pain crises. Some common triggers include infections (bacterial and viral), dehydration, exposure to cold temperatures, low oxygen environments such as airplane travel or smoke-filled rooms, and trauma. It should be recognized, however, that spontaneous, unexplained crises are common. Because these patients are functionally asplenic after early childhood, they are also at significant risk for bacterial infections, especially by encapsulated organisms such as Salmonella typhi, Haemophilus influenza type B, Streptoccoccus pneumoniae, Neisseria meningitides, and Group B streptococci. In fact, the highest rate of mortality occurs in children between the ages of 1 and 3 years as a consequence of sepsis. During the assessment of patients with sickle cell disease, the history should focus on identifying any precipitating causes and complications. Pain that is different from previous pain crises may be an indicator of a potentially life-threatening event. A rapid assess- ment of the vital signs and a careful physical examination are important, because severe complications in sickle cell crisis often present with nonspecific manifesta- tions. The clinician’s concern should be heightened if the patient has a fever, severe abdominal pain, respiratory or neurological symptoms, joint swelling, priapism, or pain that is not relieved by usual measures. Polymerization of the sickle cell hemoglobin causes the red blood cells to become rigid and sticky and formed into shapes that sometimes have the appearance of a sickle, hence the name. Infarctions in the metacarpals result in episodes of pain and swelling involving the hands and feet. Infants and toddlers with dactylitis may become irritable, refuse to walk, or cry when touched or held. These vasoocclusive episodes usually last from 3 to 9 days, but it is not atypical for those patients with longer episodes to continue to have patterns where their episodes remain prolonged. In addition to sepsis, patients are susceptible to other infections such as pneumonia, meningitis, and osteomyelitis.
