A 46-year-old woman with acute promyelocytic leukemia (APL) was treated with all-trans retinoic acid (ATRA) and chemotherapy according to the AML-92, M3 regimen of the Japan Adult Leukemia Study Group (JALSG). Between days 7 and 18 of therapy, she suffered chest discomfort, fever, cough, dyspnea and general fatigue. A chest roentogenogram showed bilateral interstitial infiltrates. Her leukocyte count began to increase rapidly to 6,400/microliters on day 14. Marked hypoxia (PO2 35.9 mmHg) suggested occurrence of retinoic acid (RA) syndrome. She underwent endotracheal intubation and mechanical ventilation with administration of methyl-prednisolone (m-PSL) pulse therapy. Her symptoms promptly abated. Therapy with ATRA was continued and her leukocyte count reached 44,800/microliters on day 19 of therapy. She achieved complete remission on day 48.

The retinoic acid derivatives are used for disorders of keratinization such as psoriasis. Acitretin, which is a synthetic, aromatic derivative of retinoic acid, is frequently used to treat psoriasis. The retinoic acid syndrome (RAS), described with all-trans-retinoic acid (ATRA) in patients with promyelocytic leukemia, is characterized by fever and respiratory distress. In this report we present a 32 year old male who developed high fever, dry cough and dyspnea while undergoing treatment with acitretin. During hospitalization, his acitretin was stopped and he was treated with corticosteroids. Significant improvement was observed within a few days.

Four new steroidal alkaloids, puqienine A (1), puqienine B (2), N-demethylpuqietinone (3), and puqietinonoside (4), along with a known steroidal alkaloid, puqietinone, were isolated from the bulbs of Fritillaria puqiensis. The structures of these compounds were elucidated on the basis of spectroscopic analysis. The compounds exhibited significant antitussive activity on ammonia liquor-induced cough in mice. Furthermore, the compounds were evaluated for activities against A549 human lung carcinoma cell line, BGC-823 human stomach adenocarcinoma cell line, SMMC-7721 human hepatocarcinoma cell line, and HL-60 human promyelocytic leukemia cell line.

Leukemic pulmonary infiltration, as an initial presentation of acute leukemia, is rare and poses a therapeutic dilemma. Leukemic infiltrate of the lung may be unrecognized, as patients can present with cough, fever and localized roentgenographic infiltrate, all suggestive of bacterial pneumonia. Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML) with distinct clinicopathologic features, such as: younger age of patients, shorter duration of symptoms before diagnosis, pulmonary infiltration with atypical promyelocytes and bleeding tendency due to disseminated intravascular coagulation (DIC). APL can become rapidly fatal if not treated early in its course. We report a case of APL with diffuse pulmonary infiltration and abnormal complete blood count. He was initially diagnosed and treated as an outpatient for community-acquired pneumonia. The patient returned with worsening pulmonary infiltrate, abnormal peripheral smear and respiratory failure, resulting in death within three months of his initial presentation. As evidenced by this case, acute leukemia should be considered in the differential diagnosis for pulmonary infiltrate and abnormal hematological findings.

Retinoic acid syndrome (RAS) is the clinical syndrome that occurs after treatment of acute promyelocytic leukemia with all-trans-retinoic acid (ATRA). The patients experience fever, dyspnea, hypotension, respiratory distress, edema and weight gain. Chest x-ray will show pulmonary infiltrates and pleuropericardial effusion. The onset of this syndrome is usually 5-21 days after ATRA treatment when white blood cell counts are rising more than 10,000/cu.mm. The authors have reported a case of RAS. The patient was a 29-year-old man who had been working in a battery manufacturing factory for 7 years. He presented with easily bruising for one month. The initial blood test showed hematocrit of 36.2%, white blood cells count of 3,200/cu.mm with 28% neutrophils, 20% lymphocytes, 2% eosinophils and 50% promyelocytes and platelet of 20,000/cu.mm. Peripheral blood smear revealed numerous fragmented red blood cells. Bone marrow examination showed hypercellularity with abnormal promyelocytes of 95% and bone marrow cytogenetics was translocation of chromosome 15 and 17 [t (15;17)(q22;q12)]. The diagnosis was acute promyelocytic leukemia and the patient was treated with ATRA 45 mg/m2/day per oral starting on day 1 and intravenous idarubicin 10 mg/n2 on day 4, 5 and 6. On day 13, he had a body temperature of 39 degrees C and a dry cough. The white blood cells were rising to 7,400/cu.mm with 16% neutrophils. On day 18, he had oliguria, high grade fever, hypotension, cough with chest pain and white blood cells rose to 21,300/cu.mm with 65% neutrophils and rising of blood urea nitrogen and creatinine. Chest x-ray showed enlarged cardiac shadow with pleural effusion. Echocardiogram revealed moderate amount of pericardial effusion. The diagnosis of RAS was made and ATRA was withdrawn. Intravenous dexamethasone 4 mg every 6 hours and hemodialysis was started. The patient's symptoms improved dramatically and bone marrow examination was in complete remission. He was subsequently given cytarabine and idarubicin as consolidation. This patient had clinical manifestation consistent with RAS, which improved after prompt treatment.

Bronchoalveolar lavage (BAL) is often performed in patients with acute leukemia developed with respiratory failure or pulmonary infiltrates. Patients usually undergo BAL to rule out infection. Occasionally, however, leukemic infiltrate may be detected. We present a series of 11 cases in which the diagnosis of leukemia was made on the BAL material. We retrospectively reviewed all BAL samples from January 1, 2006 to December 31, 2008. There were a total of 1,130 cases, of which 139 showed malignant cytology, including 10 with leukemia. Sixteen samples were unsatisfactory and 904 were benign, of which 32 had identifiable microorganisms. In additional to the 10 leukemia cases identified, two more were reviewed after the search criteria. The 12 patients (seven men, five women) ranged from 22 to 75 years old. All patients had previously biopsy-proven leukemia [two acute myelomonocytic leukemia, two acute promyelocytic leukemia, two acute myeloid leukemia (AML) with inv16, two therapy-related AML, one acute monocytic leukemia, one chronic myeloid leukemia in blast face, one AML with maturation, one myelodysplastic syndrome with excess blasts, and one large granular leukemia]. Four had a prior diagnosis of myelodysplastic syndrome. The time from initial diagnosis of leukemia to BAL ranged from 1 to 233 days, with 8 of 10 occurring within 8 days of diagnosis. Symptoms that prompted BAL included shortness of breath/hypoxia (8), fever (3), chest pain (2), and cough (2). Chest X-rays in all cases revealed opacities or consolidations mimicking an inflammatory process. Seven patients subsequently died, while three were alive, and, in remission, and two were lost to follow-up. The presence of a leukemic infiltrate can mimic infection. BAL is a relatively safe and useful diagnostic tool in this setting for differentiating a leukemic infiltrate from an infection/inflammatory infiltrate. The prognosis of patients with lung involvement of acute leukemia is poor.

A 31-year-old woman presented with secondary infertility, a history of previous miscarriage and two ectopic pregnancies. Salpingectomy had been performed for the left ruptured tubal pregnancy whereas the right unruptured tubal pregnancy was managed medically. In-vitro fertilization (IVF) was advised to treat tubal factor infertility of 2 years duration. The patient developed fever and cough on day-10 of ovarian stimulation. Complete blood count and peripheral smear with marked leukocytosis were suggestive of acute leukemia. After obtaining the patient's informed consent, 18 oocytes were retrieved. Following intra cytoplasmic sperm injection, 14 eggs were fertilized, and the resulting embryos were cryopreserved. On a referral to a hemato-oncologist, a bone marrow biopsy was performed, which confirmed acute promyelocytic leukemia (APL). Literature review suggests this to be the first case of APL reported during the course of ovulation stimulation for IVF.
