Objective: In this study, it was aimed to investigate the prevalence of type 1 hypersensitivity reaction under tuberculosis treatment and the management of hypersensitivity. Methods: The study is a case series. All of the patients who were hospitalized between 01.02.2015–01.05.2021 were examined. All patients who developed a drug-induced type 1 immediate hypersensitivity reaction were included. Antituberculosis drugs were given with the protocol made by Buhari et al. However, unlike what is stated in the protocol, pyrazinamide was given last during the administration of the drugs. Results: 2677 patients received inpatient tuberculosis treatment; type 1 immediate hypersensitivity reactions were seen in 94 (3.5%) patients. Due to missing data in the file, 81 patients were included in the study. 44 (54.3%) of the cases were women; mean age (mean ± SD) 50.7 ± 17.69 years; 76 (93.8%) of them are citizens of the Republic of Turkey; 58 (71.6%) of them were diagnosed bacteriologically; 65 (80.2%) of them were pulmonary tuberculosis. The most common skin finding was urticaria in 49 (60.5%). The drug responsible for the most common reaction was pyrazinamide. In 49 (60.5%) cases, drugs were given by desensitization and it was successful. The duration of treatment was 7.91 ± 2.5 months (6–18 months). When evaluated in terms of treatment results, 68 (84%) patients successfully completed the treatment. Conclusion: Our study is the largest series of patients who developed type 1 immediate hypersensitivity reaction while receiving antituberculosis treatment. A practical, easy desensitization scheme has been shared.

Alpha-gal allergy is the sensitization to Alpha-gal present in saliva when a tick bites and the development of an IgE-mediated reaction to Alpha-gal also present in red meat by cross-reactivity. In contrast to other food allergies, symptoms occur as late as 2-6 hours after a meal. Prick to prick testing with nonmammalian meat in combination with cooked mammalian meat is recommended for diagnosis. However, the main diagnostic test is Alpha-gal sIgE> 0.1 IU/mL. The primary recommendation in patients with Alpha-gal syndrome is to prevent new tick bites and avoid all mammalian meats. Since most of the dishes in our country's food culture contain red meat, elimination diet may adversely affect patients quality of life. In the management of these patients, the option of desensitization with red meat can be considered by evaluating the benefit-risk ratio together with the patient. Our patient with a history of tick bites and a reaction pattern ranging from urticaria to anaphylaxis two hours after meat consumption was evaluated for Alpha gal allergy. The patient was found to be positive by prick-to-prick with cooked red meat. In addition, the high level of Alpha-gal specific IgE (27.3 Ku/L) confirmed the Alpha-gal allergy, and the decision to apply desensitization with red meat was taken. There are only two literatures on this subject, one of which includes two adult cases and the other a single pediatric case. Since a reaction developed in the fifth step of the 27-step desensitization scheme (Ünal et al.), which we took as a reference, which led to a dose increase of more than 100 times, we modified the protocol by using an intermediate steps. We repeated the prick-to-prick test with red meat after desensitization in our case who successfully completed the modified desensitization protocol. Observation of more than half reduction in test edema diameter concretely supports the success of our modified desensitization protocol.

To evaluate drug resıstant tuberculosis patients who developed drug hypersensitivity to antituberculosis drug. This was a retrospective study. The primary aim of the study is to determine the demographic and clinical characteristics of patients who develop drug hypersensitivity in drug resistant tuberculosis patients. The secondary aim of the study is to examine the treatment results. Demographic features, tuberculosis diagnostic indicator, clinical signs of developing hypersensitivity reaction, reaction time, and treatment were evaluated. A total of 25 patients were included in the study. The prevalence of hypersensitivity in drug resistance patients was 11.9%. Twelve (48%) of the cases were women. Mean age (mean ± SD) was 37.24 ± 14.44 years; early type hypersensitivity reaction in 13 (52%). Three patients were isoniazid resistant; 19 patients were multidrug-resistant (MDR); 2 patients were pre-extensive drug resistant (Pre-XDR), 1 patient was extensive drug resistance (XDR) tuberculosis. The most common skin findings were maculopapular eruption and urticaria. But also we had seen ısole angıodema, urtıcarıa and angıoedema, erythema multıforme, lıchenoıd drug eruptıon and drug rash with eosinophilia and systemic symptoms. In patients who developed a hypersensitivity reaction, the responsible agent was identified in 14 cases in total. Among the drugs, pyrazinamide, ethambutol, moxifloxacin, amikacin, para amino salicylic, prothionamide, and cycloserine are the responsible agents. When evaluated in terms of treatment results, 15 (60%) patients successfully completed the treatment. Our study is the first study in the literature that evaluated the drug hypersensitivity in drug resıstance tuberculosis patients. Drug hypersensitivity that develops with tuberculosis treatment may lead to discontinuation or change in treatment. İt can cause treatment failure, drug resistance, relapse, and even death. In resistant tuberculosis, the already existing resistance pattern may become more difficult to treat. Success can be achieved with the right management in these patients who have few treatment options, more drug side effects, and high treatment failure rates. The established regimen should be curative and prevent recurrence.

Background: In the perioperative period, patients are exposed to many agents that may cause hypersensitivity reaction; so, finding the culprit drug is important for patient safety in the event of the need for repeat anesthesia. Aim: Our aim was to share demographic data, clinical features, and diagnostic tests of patients who developed perioperative hypersensitivity (POH) and in whom the culprit drug was identified. Methods: Patients evaluated for POH between 2016 and 2024 were retrospectively analyzed. Results of anesthesia notes, agents used in anesthesia, skin prick test, and intradermal test (IDT) to determine the culprit drug were examined. Patients were interviewed by telephone and questioned about their reanesthesia status. Results: The files of 167,688 patients were analyzed; 405 patients were referred and tested for POH and 330 patients were excluded from the study because they had no history of POH or the culprit drug could not be identified. The study was completed with 75 patients. POH developed during the induction of anesthesia (I) in 18, maintenance (M) in 34, and at the end (E) in 23 patients. The median age was 48, out of which 89.3% (n = 67) were females. Reactions developed during genitourinary system surgery in 33.3% (n = 25), ear-nose-throat surgery in 17.3% (n = 13), and abdominal surgery in 17.3% (n = 13); anaphylaxis developed in 56% (n = 42) (I: 9; M: 21; E: 12); cutaneous involvement in 73.3% (n = 55); cardiovascular involvement in 41.3% (n = 31), respiratory system involvement in 56% (n = 42), and gastrointestinal involvement in 4% (n = 3); Brown grade 1 in 44% (n = 33) and grade 3 in 38.7% (n = 29); Ring and Messmer classification, grade 1 in 44% (n = 33); and cardiac arrest in five patients. For the distribution of culprit drugs: neuromuscular blocking agents (NMBAs) in 22.7%, opioids in 21.4%, hypnotics in 17.3%, and antibiotics in 14.6%. In four patients, multiple agents were determined. Skin prick test was positive in 35.1% and IDT positivity was found in 98.6%. Surgery was cancelled in 40% (n = 30), but it was determined that 50 patients (66.7%) underwent surgery after drug tests. All of them tolerated surgery. Conclusıon: A large number of patients were evaluated because we are a reference hospital. The most common culprit drug group in POH is NMBA; reanesthesia situations are safe after allergist evaluation.

Background: The coinfection of Mycobacterium tuberculosis and SARS-CoV-2 is called tuberculosis and COVID-19 coinfection (TB–COVID-19). We aimed to share the clinical, radiological, and laboratory findings and treatment processes of our patients with TB–COVID-19 coinfection in our tertiary reference hospital. Methods: Patients aged 18 years and over and hospitalized in the tuberculosis service between March 2020 and September 2022 were included. All coinfected patients whose COVID-19 polymerase chain reaction results were positive while receiving tuberculosis treatment or who were diagnosed with tuberculosis while receiving treatment for COVID-19 were included. Results: The number of patients was 39; 61.6% of males; the mean age was 52 ± 17.1 years; 20% were foreign nationals; 92.5% were Asian; 69.5% had a bacteriological diagnosis; 84.6% had pulmonary tuberculosis; 10% had received antituberculosis treatment before; and 87.5% were sensitive to the first-line antituberculosis drugs. The most common comorbidities were diabetes and hypertension. 87.5% of the patients were diagnosed with tuberculosis and were superinfected with COVID-19 while receiving tuberculosis treatment. 49.5% of patients had received at least one dose of COVID-19 vaccine. The most common presenting symptom was cough and sputum; the prominent laboratory parameter was C-reactive protein increase, and thorax computed tomography finding was consolidation, tree-in-bud, and cavitation. While 45.9% of the patients were still under treatment, 1 (2.5%) patient also resulted in mortality. Conclusion: In this study, attention was drawn to two infectious diseases seen with respiratory tract symptoms. The mortality rate was found to be low. Neither disease was found to be a factor aggravating the course of each other.
