RESUMO
BACKGROUND: R-CHOP-21 has been the standard treatment for diffuse large B-cell lymphoma (DLBCL), but there is a paucity of evidence focusing on the number of cycles of regimens. PATIENTS AND METHODS: We conducted a retrospective study to compare the effectiveness of six cycles of standard regimens versus eight cycles for overall survival (OS) in DLBCL patients using propensity score matching, in consideration of relative dose intensity (RDI). RESULTS: A total of 685 patients with newly diagnosed DLBCL were identified in three institutions from 2007 to 2017. Patients treated using six cycles of standard regimens were matched by propensity scores with those treated using eight cycles. A 1 : 1 propensity score matching yielded 138 patient pairs. Eight cycles did not significantly improve OS in the conventional Cox proportional hazards model (hazard ratio 0.849, 95% confidence interval 0.453-1.588, P = 0.608). Restricted cubic spline Cox models for OS confirmed that the effect of the number of cycles was not modified by total average RDI, the International Prognostic Index, and age. Occurrence of adverse events did not differ between six and eight cycles. CONCLUSION: Even considering the impact of RDI, six cycles of the initial standard regimen for DLBCL is not inferior to eight cycles.

Acute fatty liver of pregnancy complicated with anterior pituitary insufficiency in a 24-year-old nullipara woman who presented fever and progressing liver damage after the delivery by Cesarean section is described. The liver biopsy revealed severe fatty changes with microvesicular fat drops in the hepatocytes. Serum growth hormone and adrenocorticotropic hormone levels were low, and did not respond to the stimulation. The daily urinary excretion of 17-hydroxycorticosteroid was also low. Acute fatty liver of pregnancy and antehypophyseal insufficiency were diagnosed. Secondary adrenal failure was also suspected. The co-existing hypercoagulable state could cause an ischemic attack on the pituitary gland.

A cDNA clone, which has an open reading frame of 1398 nucleotides encoding a 466-amino-acid peptide, has been isolated from rabbit liver cDNA library. Compared with the peptide sequence, it shows high homology to alpha1a adrenoceptors of human, bovine and rat. We expressed this clone in COS-7 and investigated the pharmacological properties, revealing similarity to those of human alpha1a adrenoceptors. Competitive RT/PCR has detected the mRNA in variety of rabbit tissues, especially abundantly in liver, vas deferens, brain, and aorta, but not in heart.
