Acute graft-versus-host disease GVHD (aGVHD) is the main complication during the first months after bone transplantation. Steroid therapy is clearly the upfront established treatment for aGVHD. However, there are patients with partial response to steroid treatment and steroid-refractory cases. For those patients, a vast number of therapeutic options have emerged, although the evidence is scarce.

We report the use of tocilizumab as salvage treatment in a patient with corticosteroid refractory pulmonary aGVHD that was admitted to the critical care unit for respiratory support measures.

We decided to use tocilizumab as rescue treatment, after failure of corticosteroid treatment, standard treatment with broad-spectrum antibiotics and etanercept. The patient showed a remarkable clinical improvement two days after first infusion and a total resolution of the symptomatology with normalization of the spirometry tests after 4 weeks of the administration of tocilizumab.

To the authors' knowledge, this is the first case that describes the effective and safe use of tocilizumab as a rescue treatment in a patient with steroid-refractory pulmonary aGVHD. It showed a rapid onset of action and a favorable safety profile, which could make it an interesting option for the treatment of this potentially fatal complication.

Although imatinib is the first-line of therapy for Philadelphia chromosome (Ph)-positive chronic myeloid leukemia (CML), in Japan, it is recommended by the manufacturer that lactating women treated with imatinib mesylate for CML should discontinue breastfeeding their infants.

A 32-year-old pregnant patient was diagnosed with Ph-positive CML at 13 weeks of gestation. She received imatinib (400 mg/day) after 28 weeks of gestation. A female infant was delivered at a gestational age of 35 weeks and 3/7 days after preterm premature rupture of membranes. It was decided to feed only colostrum to the infant and formula feeding was done subsequently because of the risk of the transfer of imatinib to breast milk. The milk/plasma (M/P) ratio and the relative infant dose (RID) for imatinib were calculated to be 0.35 and 1.4%, respectively at 5 days of life. Moreover, the serum level of imatinib in the child of age 5 days was 27 ng/mL, which was much lower than the target trough value for CML (1000 ng/mL).

The M/P ratio and RID values for maternally administered imatinib were within the safe range for breastfeeding, as reported in previous studies. In addition, it was found that the serum concentration of imatinib in the child was relatively low during short-term breastfeeding.

Hypersensitivity reactions (HSRs) to rituximab occur during the first infusion in 29% to 40% of patients. Commonly, these hypersensitivity reactions are the result of a release of cytokines, although IgE mediated reactions have also been reported.

A 7-year-old female patient with diagnosis of CD-20 positive acute lymphoblastic B-cell leukemia was included in a pilot study that consisted of two doses of rituximab treatment in the induction to remission phase by the pediatric hematology service; 30 minutes after the first administration of 300 mg of rituximab the patient started with generalized rash, nausea, vomiting, tachycardia, dyspnea, foreign body sensation in throat, oxygen desaturation until 89% and hypotension; therefore, the infusion of rituximab was suspended, and intramuscular epinephrine was administered as well as intravenous hydrocortisone and chlorphenamine and supplemental oxygen supply with adequate resolution of symptoms.

Intradermal skin testing with rituximab at the concentration 1 mg/ml (dilution 110), was positive. Desensitization to rituximab was indicated by our service with 4 bags - 16 steps protocol with an initial concentration dose of 1/1,000 of the total dose. The patient was premedicated 1 hour prior with intravenous chlorphenamine, methylprednisolone and ondansetron. Intravenous prophylactic fluids with normal saline solution were administered during the infusion. The procedure was carried out with close monitoring of vital signs in a course of 6.67 hours, without presenting hypersensitivity reactions.

HSR to rituximab may be induced by the activation of mast cells and basophils. Desensitization protocols are developed when there is no alternative drug for the underlying condition.

Endovascular aneurysm repair has become the primary treatment modality for ruptured infrarenal abdominal aortic aneurysm. This study examines the impact of endograft type on perioperative outcomes for ruptured infrarenal abdominal aortic aneurysm.

The targeted endovascular aneurysm repair files of the American College of Surgeons National Surgical Quality Improvement Program database (2012-2017) were used. Only patients treated for ruptured infrarenal abdominal aortic aneurysm were included. click here All patients requiring concomitant stenting of the visceral arteries or aneurysmal iliac arteries or open abdominal surgery were excluded. The characteristics of patients treated with the different endografts and the corresponding outcomes were compared using Stata software.

There were 479 patients treated with the three most common endografts Cook Zenith (
 = 127), Gore Excluder (
 = 239), and Medtronic Endurant (
 = 113). The number of other endografts was too small for statistical analysis. Compared to patients treated with Excluder or Endurant, the patients treated with Zenith had significantly lower body mass index (
