A rapid and simple procedure measuring the rate of hemolysis of 50% of erytrocytes suspended in a standardized glycerol mixture (GLT/50) has been compared with the erytrocyte osmotic fragility to NaCl 0.375% concentration, carried out according to Parpat's method modified, in order to estimate the respective behaviour in the screening of beta-thalassemia trait. The GLT/50 is provided with more selectivity especially between beta-thalassemia trait carriers and other subjects with iron deficiency anemia.

A new test for the laboratory diagnosis of spherocytosis, conventionally called 'Pink test', is presented. This test, semi-quantitatively or quantitatively, determines the hemolysis of small blood samples in a solution containing glycerol (135 mmol/l), NaCl (25 mmol/l), NaN3 (1.5 mmol/l), buffered to pH 6.66 with Bis-Tris (70 mmol/l) and HCl. 'Pink test', as well as 'acidified' glycerol lysis test, were positive in 100% of 42 patients suffering from hereditary spherocytosis, and optimally discriminated them from healthy subjects, showing a diagnostic sensitivity greater than 'standard' glycerol lysis test and osmotic fragility in hypotonic saline solutions of fresh or incubated blood. 'Pink test' was also positive in some cases of renal failure, immunohemolytic anemia, chronic hemoproliferative disorders, normal pregnant women, and negative in other microcytic anemias (beta-thalassemia, iron deficiency anemia). The results do not critically depend on pH of the solution (differently from those obtained with 'acidified' glycerol lysis test), and for this reason they show a good reproducibility.

We report a 43-year-old Japanese woman with microcytic and hypochromic anemia, who had been erroneously diagnosed as having iron deficiency anemia 20 years previously at the time of her first labor, and treated with iron and blood transfusion. At the present visit to our clinic, she was found to have an increased HbA2 level and prolonged glycerol lysis time. Genetic analysis of the beta-globin gene revealed deletion of 3 bases at codons 127/128 (CAG/GCT-->CCT). A genetic study of the patient's family showed that two of her four children possessed the same mutation. The patient had mild anemia, her first son had very mild anemia, and her second daughter had moderate anemia with hemolysis. These affected family members were diagnosed as having dominant-phenotype beta-thalassemia.

A 40-year-old woman was diagnosed with iron deficiency anemia (hemoglobin 3.5 g/dl) induced by uterine myomas, and admitted to the Department of Gynecology of our hospital. During admission, she underwent the daily intravenous administration of saccharated ferric oxide for 3 weeks, and monthly GnRH analogue administration was started. Her hemoglobin level acutely increased to 9.3 g/dl over the next 18 days with normal blood pressure. Thirteen days after the 3rd administration of the GnRH analogue, she suddenly developed marked headache. Just before the onset, she had been driving a car, and spun the steering wheel to avoid a traffic accident on a busy street. This headache was so severe that she was brought to our hospital by ambulance. During transport to the hospital, her blood pressure was normal. Soon after arriving, she developed generalized convulsions, followed by status epilepticus. A brain MRI showed vasogenic edema in the posterior and parietal cortices including white matter bilaterally, and minimum subarachnoid hemorrhage was indicated in the bilateral frontal lobe and right temporal lobe. CSF analysis was unremarkable. Anticonvulsants, one course of steroid pulse therapy and glycerol were started, and status epilepticus disappeared on the same day. Abnormal areas on MRI decreased gradually. However, hyperintensity on T1- and FLAIR images remained in the right parietal lobe and bilateral occipital lobe white matter at 15 months after the onset Judging from the clinical and radiological findings, this patient was diagnosed as reversible posterior leukoencephalopathy syndrome (RPLS) accompanied with subarachnoid hemorrhage. This case suggests that an unexpected prompt physical activity or astonishment would induce RPLS in a patient treated with GnRH analogue.
