HELLP, a syndrome characterized by hemolysis, elevated liver enzyme levels and a low platelet count, is an obstetric complication that is frequently misdiagnosed at initial presentation. Many investigators consider the syndrome to be a variant of preeclampsia, but it may be a separate entity. The pathogenesis of HELLP syndrome remains unclear. Early diagnosis is critical because the morbidity and mortality rates associated with the syndrome have been reported to be as high as 25 percent. Platelet count appears to be the most reliable indicator of the presence of HELLP syndrome. The D-dimer test may be a useful tool for the early identification of patients with preeclampsia who may develop severe HELLP syndrome. The mainstay of therapy is supportive management, including seizure prophylaxis and blood pressure control in patients with hypertension. Women remote from term should be considered for conservative management, whereas those at term should be delivered. Some patients require transfusion of blood products, and most benefit from corticosteroid therapy. Rarely, patients with refractory HELLP syndrome require plasmapheresis.
Nuclear medicine imaging techniques can help in patient evaluation where infectious and non-infectious inflammatory disorders are suspected. When selected and tailored to the clinical situation, most techniques already in use or available soon provide information with high sensitivity. However, almost all currently available techniques lack the specificity to discriminate between infectious and non-infectious inflammation. In undiagnosed fever, this non-specificity may be an advantage since fever of unknown origin is caused by infection in only about 25% of cases, but in the postoperative patient the reliable differentiation between infection and sterile inflammation is highly relevant to clinical management. The range of radiopharmceuticals to investigate infectious and non-microbial inflammatory disorders is expanding and developments in protein/peptide chemistry and in labelling technology should lead to agents with very high specific activities. Nuclear medicine has to add specificity to its already high sensitivity if it is to distinguish both categories of inflammatory disorder.
