Mastocytosis is a disorder characterized by abnormal mast cell proliferation and accumulation in one or more tissues. It presents in two major variants: cutaneous mastocytosis and systemic mastocytosis. Because the symptoms are related to mast cells, histamine receptor antagonists and leukotriene receptor antagonists are recommended as therapeutic options. Here, we report a 54-year-old male patient with a history of urticaria pigmentosa who presented with recurrent anaphylaxis. His serum tryptase level was 31.7 ng/mL and mast cell infiltration was observed in his bone marrow. He had frequent attacks of anaphylaxis despite treatment with ketotifen, levocetirizine, and montelukast. Symptoms related to systemic mastocytosis were controlled and the patient exhibited no recurrence of anaphylaxis following the introduction of monthly omalizumab injection. Omalizumab can be considered as a treatment option in patients with systemic mastocytosis unresponsive to conventional oral medications. 저자들은 빈번한 아나필락시스를 보이는 환자에서 비활동성 비만세포증을 확진하였으며, omalizumab으로 효과적으로 치료하였기에 문헌고찰과 함께 보고하는 바이다.

Background: Obesity is related to several comorbidities and mortality, but its relationship with acute kidney injury (AKI) and long-term mortality remain undetermined in patients undergoing coronary artery bypass grafting. Methods: Data from 3,018 patients (age ≥ 18 years) who underwent coronary artery bypass graft surgery from two tertiary referral centers were retrospectively reviewed between 2004 and 2015. Obesity was defined using the body mass index, according to the World Health Organization's recommendation. The odds and hazard ratios in post-surgical, AKI, and all-cause mortality were calculated after adjustment for multiple covariates. Patients were followed for 90 ± 40.9 months (maximum: 13 years). Results: Among the cohort, 37.4%, 2.4%, 21.1%, 35.1%, and 4.0% of patients were classified as normal weight, underweight, overweight-at-risk, obese I, and obese II, respectively. Post- surgical AKI developed in 799 patients (26.5%). Patients in the obese groups (overweight-at- risk to obese II) had a higher risk of AKI than did those in the normal-weight group. During the follow-up period, 787 patients (26.1%) died. Underweight patients had a higher risk of mortality than did normal-weight patients, whereas overweight-at-risk, obese I, and obese II patients showed better survival rates. Conclusion: After coronary artery bypass graft surgery, obese patients encountered a high risk of AKI, and underweight patients exhibited a low chance of survival. Awareness of both obese and underweight statuses should be raised in these patients.

Anaphylaxis is a sudden-onset life-threatening systemic hypersensitivity reaction. Allergens, such as foods, stinging insect venoms, and drugs, are the globally important causative factors for anaphylaxis. Para-phenylenediamine (PPD), an aromatic amine, is a well-known hair dye component that can act as a skin irritant and/or a skin sensitizer. As an allergen, PPD can induce various reactions; the most common being contact dermatitis, a delayed-type hypersensitivity reaction. Anaphylaxis or other immediate hypersensitivity reactions by hair dye contact is extremely rare, with only a few cases reported worldwide. Here, we report a case of a 63-year-old female who presented to the Emergency Department with dyspnea, rash, vomiting, and diarrhea within minutes after using a hair dye product containing PPD. Her past medical history includes urticaria of unknown cause. Her total IgE antibody level was increased to 630 kU/L. Skin prick and patch tests with the hair dye she applied at the time of anaphylaxis demonstrated an immediate reaction. An additional patch test with 25 common contact allergens showed positive reaction to PPD. This is the first case report of hair dye-induced contact anaphylaxis presenting sensitization to PPD in Korea.
