The use of imatinib mesylate (Gleevec), a selective tyrosine kinase inhibitor, has become the new gold standard for the treatment of chronic myeloid leukemia. Unfortunately, the medication has been commonly associated with mild to severe cutaneous reactions, which has limited its use for some patients. We describe a case of a successful progressive challenge of a patient with a drug-induced exanthem from imatinib mesylate and a review of the literature.

Progesterone induced dermatitis is a rare disorder. It typically occurs in females due to an autoimmune phenomenon to endogenous progesterone production, but can also be caused by exogenous intake of a synthetic progestin. Here in, we present a case of autoimmune progesterone anaphylaxis (AIPA) observed in an adolescent female. The patient is an 18-year-old Caucasian female with no significant past medical history and no prior exogenous hormone use, who presented to her primary care physician complaining of cyclic skin eruptions with dyspnea, cough and respiratory distress. She noted that her symptoms occurred monthly, just prior to her menses. An intradermal skin test using 0.1 cml of progesterone was performed. The patient developed a 15 mm wheal after 15 minutes, confirming the diagnosis of AIPA. The patient was started on a continuous regimen of an oral conjugated estrogen (0.625 mg). The skin eruptions and respiratory symptoms have not returned since the initiation of this therapy. Autoimmune progesterone dermatitis manifests via the occurrence of cyclic skin eruptions. Women with the disorder commonly present with dermatologic lesions in the luteal phase of the menstrual cycle, if there are any other organ involvement in addition to skin (e.g. lung, GI) the reaction should be called as autoimmune progesterone anaphylaxis. Diagnosis of AIPA is confirmed by performing a skin allergen test using progesterone.

Previous studies demonstrated significant differences in a number of HLA allele frequencies in leukemia patients and normal subjects. In this study, we have analyzed HLA class II alleles and haplotypes in 110 leukemia patients (60 acute myelogenous leukemia "AML", 50 chronic myelogenous leukemia"CML") and 180 unrelated normal subjects. Blood samples were collected from all of the patients and control subjects. DNA was extracted by salting out method and HLA typing was performed using PCR-SSP method. Significant positive association with AML was obtained for HLA-DRB1*11allele (35% vs. 24.7%, P=0.033). Two alleles including HLA-DRB4 and -DQB1*0303 were significantly less frequent in AML patients than in controls. HLA-DQB1*0303 allele was never observed in CML patients compared with allele frequency in controls (4.2%). According to haplotype analysis, HLA-DRB1*0101/DQA1*0104/-DQB1*0501 frequencies were significantly higher and -DRB1*16/-DQA1*01021/-DQB1*0501 frequencies were significantly lower in CML patients than in controls. In conclusion it is suggested that HLA-DRB1*16 allele and HLA-DRB1*15/-DQA1*0103/-DQB1*06011 and -DRB1*16/-DQA1*01021/-DQB1*0501 haplotypes predispose individuals to AML and HLA-DRB4 allele predispose to CML. Future studies are needed to confirm these results and establish the role of these associations in AML and CML.

N(epsilon) -(carboxymethyl)lysine (CML) expression is selectively present in the lower respiratory tract. We compared CML levels in exhaled breath condensate (EBC) between 19 asthmatics and 10 normal control subjects and its levels before and after tiotropium therapy in 11 non-smoking asthmatics and 10 smoking asthmatics. CML levels were significantly lower in asthmatics than in normal control subjects. Moreover, low CML level was associated with small airway dysfunction. After tiotropium therapy, CML level in non-smoking asthmatics was unchanged, while that in smoking asthmatics was significantly increased. Therefore, CML level in EBC is a non-invasive biomarker for evaluating small airway involvements in asthma.

Some of the genotypes of cytokines are associated with acute graft versus host disease after bone marrow transplantation. The purpose of the present investigation was to find out the possible association between transforming growth factor beta-1 (TGF-beta1) codon 25 polymorphism (rs:1800471) and acute graft versus host disease (aGVHD) after bone marrow transplantation from the sibling with the similar HLA among the Iranian population. In this retrospective case-control investigation, 172 subjects including 86 Iranian patients and their siblings with the similar HLA as donor/recipient pairs were recruited. All of the patients were diagnosed with one group of blood disorder consisting of Acute Myeloid Leukemia (AML)=40, Acute Lymphoblastic Leukemia (ALL)=25 and Chronic Myeloid Leukemia (CML)=21. PCR-SSP method was carried out to ascertain TGF- beta1 codon 25 G/C polymorphism genotypes. The frequency of TGF- beta1 codon 25 GG, GC and CC genotypes among all cases were 77.3%, 21.5% and 1.2%, respectively. Recipients with the GG genotype developed severe aGVHD significantly more than those with CC or GC genotypes (Odds Ratio =12.133, P=0.015). Genetic background of TGF-beta1 may be involved in aGVHD development and/or severity in the patients who received Bone Marrow Transplantation (BMT) from their siblings with the similar HLA among the Iranian population.
