ABSTRACT
INTRODUCTION: Sertraline is a selective serotonin reuptake inhibitor which is often used as first-line treatment for depression. Several patterns of interstitial lung disease attributable to sertraline have been reported in the literature. CASE REPORT: A 69-year-old patient, who had been taking sertraline to treat severe depression for 10 months, presented with a deterioration in his general condition and respiratory symptoms found to be associated with bilateral pneumonitis. An exhaustive assessment did not reveal any infectious or autoimmune aetiology. Transthoracic lung biopsy revealed a pattern of eosinophilic lung disease. Sertraline-induced lung toxicity was then suspected and this treatment was therefore stopped. The patient's symptoms resolved and the chest imaging normalized. CONCLUSIONS: Our observation suggests that sertraline was the cause of chronic eosinophilic pneumonia characterized by an insidious clinical presentation several months after starting the medication. Given its widespread prescription, we encourage any clinician facing this disease to pay attention to possible drug-induced origins of lung disease.

Controlled-rate freezing and storage in vapour phase nitrogen are used by most transplantation teams for the cryopreservation and storage of peripheral blood haematopoietic stem cells (PBSC). In this study, we analysed 666 autologous PBSC transplants after uncontrolled freezing and storage of PBSC at -80 °C. Statistical analysis showed that neutrophil recovery was associated with both the infused CD34(+) cell dose (P=0.01) and the post transplantation use of growth factors (P<0.001) and that platelet recovery was associated with the infused CD34(+) cell dose (P<0.001) and with the diagnosis (P=0.02). We analysed three groups according to the duration of the cryopreservation period (less than 6 months, between 6 and 12 months or more than 1 year). Haematopoietic recovery was not found to be adversely affected by longer storage at -80 °C. The haematopoietic recoveries of 50 pairs of sequential transplantations from the same PBSC mobilization were analysed. Despite prolonged cryopreservation, there were no statistically significant differences in neutrophil (P=0.09) or platelet (P=0.22) recovery in the second compared with the first transplant. In conclusion, the long-term storage of PBSC at -80 °C after uncontrolled-rate freezing is an easy and comparatively inexpensive cryopreservation method that leads to successful haematopoietic recovery even after prolonged storage.

We report a case of bacteremia caused by Solobacterium moorei, an anaerobic, non-sporulated Gram-positive bacillus in a patient with a multiple myeloma. The source of infection was presumably related to multiple dento-alveolar abscesses. This is the first recovery of S. moorei from blood cultures.

OBJECTIVES: Follicular lymphoma (FL) is the most common adult non-Hodgkin's lymphoma. Diagnosis is based on morphology and can be confirmed by cytogenetic, flow cytometry (FCM) or molecular studies. Despite all these complementary approaches, diagnosis sometimes remains difficult. The purpose of the present work was to characterise the expression of new specific follicular cells markers which allows us to target specifically the abnormal FL cell population in FCM. METHODS: A total of 153 samples from healthy subjects and from patients with chronic B-cell lymphoproliferative disorders were analysed by FCM in the same conditions for purpose of comparison. RESULTS: We showed that CD44 is weakly expressed in FL cells compared with peripheral blood mononuclear cell from normal blood donors and others cells from B lymphoproliferative diseases. We nevertheless observed bone marrow samples where some immature B-cell population express CD44 with lower fluorescence intensity. Therefore, we developed a double antibody combination, using CD44 and CD38, which allowed us to separate the normal immature cells from the pathological population using FCM. CONCLUSION: This new phenotypic approach offers an accurate (sensitivity and specificity of 93% and 96%, respectively), fast and low sample consuming method for the diagnosis of FL.
