The long-term outcomes of mepolizumab treatment at 100 mg dose on idiopathic chronic eosinophilic pneumonia: A real-life experience.

Background: The standard therapeutic regimen for idiopathic chronic eosinophilic pneumonia (ICEP) involves the administration of oral corticosteroids (OCS). However, a notable proportion of individuals experience recurrent episodes after the tapering or cessation of OCS during the course of ICEP. There has been a growing interest in exploring alternative treatment modalities for patients with ICEP at heightened risk of relapse. Objective: The aim of this study was to assess the efficacy of mepolizumab at a dose of 100 mg administered every 4 weeks in preventing relapses of ICEP and its impact on the clinical outcomes. Methods: This retrospective clinical observational study used real-world data to assess the impact of mepolizumab on patients diagnosed with ICEP accompanied by severe asthma. Demographic information and clinical characteristics were extracted from medical records. The study examined the effect of mepolizumab on the annual relapse rate, OCS dose, eosinophil count, and respiratory function parameters. Results: All patients included in the study, with a median (range) follow-up period of 19 months (4-40 months), the annual relapse rate decreased from 0.33 to 0 after the initiation mepolizumab. In addition, the maintenance OCS dose, expressed in methylprednisolone equivalents, declined from 4 mg/day to 0 mg/day. A reduction in the blood eosinophil count was observed, alongside a partial improvement in respiratory function test results among the patients. Conclusion: A dose regimen of 100 mg of mepolizumab administered every 4 weeks emerges as a promising and well-tolerated therapeutic approach for averting relapses of ICEP.

Rapid drug desensitization to taxanes: a descriptive study from Turkey.

AIM: To present the characteristics of drug hypersensitivity reactions (DHRs) among taxane recipients with non-small cell lung carcinoma (NSCLC), and to describe the results of rapid drug desensitization (RDD). METHODS: A retrospective cross-sectional study included 45 patients who were treated with taxane for NSCLC and were found to be hypersensitive to taxane. All patients were administered the standard 3-bag, 12-step RDD protocol following the development of DHR. RDD success was evaluated separately for each cycle, and successful RDD was defined as the completion of the cycle with application of 12 steps of the desensitization protocol and the absence of early and/or late reactions afterwards. RESULTS: Among 45 patients hypersensitive to taxane 43 (95.6%) successfully received taxane cycles with desensitization. Failed RDD occurred in only 2 (4.4%) patients. The total number of desensitization cycles was 183, of which 181 (98.9%) were successful. The mean age of patients with successful desensitization was 59.42 ± 10.48 years and 37 (86.0%) of them were male. CONCLUSION: RDD is a reliable procedure that enables effective administration and completion of first-line taxane treatments in taxane-sensitive patients.

Regional variability of modified Ferriman-Gallwey scorring in premenopausal healthy women in Southern Turkey.

ObjectiveAlthough modified Ferriman-Gallwey (mF-G) scorring has been the gold standard for assessing hirsutism, also known that this scorring could show variability according to ethnicity. Hence, false positive hirsutism diagnosis and unnecessary anti-androgen therapy can prescribed. It was aimed to disclose the regional characteristics of this scorring in healthy women living in Southern Turkey.Methods360 women between 18 and 50 years of age were randomly screened. Their medical history, including ovulation periods, gestation(s), family history, known drug use was obtained. Physical examination with mF-G scoring and serum hormone measurements were performed. Women with hirsutism who scored ≥ 8 were further investigated for any underlying disease or cause of hirsutism. After these investigations, the women were divided into three groups according to the mF-G ≥ 8 score and evaluated. Group A (n = 59) had an mF-G ≥ 8 and, revealed an underlying disease causing hirsutism; group B (n = 42) had an mF-G ≥ 8, but no underlying disease responsible for hirsutism; and the third group (Group C, n = 259) had an mF-G ≤ 8 and thus, no signs of hirsutism.ResultsThe mean mF-G scores of three groups were 12.78 ± 4.4, 11.48 ± 4.6, and 5.53 ± 3.4, respectively. Of the 59 (16.1%) women in Group A, 46 (44.2%) were diagnosed as polycystic ovary syndrome (PCOS), 8 (7.7%) had idiopathic hyperandrogenism, 7 (6.7%) had nonclassic congenital adrenal hyperplasia, and 1 (1%) had a prolactinoma. When compared to group B, group A women had significantly decreased fertility (p = .001) and menstrual irregularities (p = .001).ConclusionsIn this study, results revealed a significant rate of healthy women (11.6%) who had an mF-G ≥ 8, but no underlying disease causing hirsutism yet were considered hirsute according to their mF-G cutoff. Also, the majority of the studied women (71.9%) living in Southern Turkey were found to have a hair-pattern similar to the European Women. Therefore, we suggest that regional and ethnical body-hair patterns should be considered before prescribing anti-androgen therapy.

Successful desensitization under antihistamine suppression in a case with urticaria due to osimertinib.

INTRODUCTION: Osimertinib is an approved therapy for patients with a Thr790met (T790M) mutation diagnosed with non-small cell lung cancer (NSCLC) that progresses during epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy. However, in 7-13% of patients, drug-related side effects lead to discontinuation of osimertinib treatment. In such cases, osimertinib desensitization is a treatment option that can be considered. CASE REPORT: A 59-year-old female patient, who was followed up with the diagnosis of stage 4 NSCLC, was consulted to the allergy clinic because of urticaria. The patient developed urticaria plaques 20 h after the third dose of osimertinib tablet. MANAGEMENT & OUTCOME: With the diagnosis of osimertinib-induced urticaria, desensitization was planned for the patient. Treatment was started with a dose of 0.1 mg/day osimertinib. The procedure was completed in approximately 50 days, and a dose of 80 mg/day was reached with antihistamine suppression. DISCUSSION: Here, a successful osimertinib desensitization in a patient with a history of osimertinib-related type 1 allergic reaction is reported. Osimertinib desensitization is a treatment option that should be considered in cases where treatment has to be ceased due to drug-related side effects.

Hypersensitivity reactions with first-line antituberculosis drugs and outcomes of rapid desensitizations.

Background: Data about drug hypersensitivity reactions with first-line antituberculosis drugs and their management is limited. Rapid drug desensitization seems to be an appropriate management. Objective: Evaluate the efficacy of the rapid desensitization protocols in patients who had a reaction phenotypically compatible with immediate-type drug hypersensitivity with first-line antituberculosis drugs and identify possible risk factors of breakthrough reactions during the protocols. Methods: This is a retrospective study of active tuberculosis patients who had a reaction phenotypically compatible with immediate-type drug hypersensitivity with first-line antituberculosis drugs and underwent desensitization with the drugs used during the reaction. Characteristics of drug hypersensitivity and breakthrough reactions, and outcomes of rapid desensitizations were recorded. Results: One hundred and seventy-nine patients were included in the study. Most of the initial reactions (n = 132, 73.7%) occurred within the first week of treatment and were mild (n = 146, 81.6%). A total of 690 desensitizations were performed. Desensitizations were successfully completed without any breakthrough reaction in 103 (57.5%) patients and in 29 of 36 (80.6%) patients after a breakthrough reaction. The overall success of desensitizations were found to be 95% (132 of 139 patients). Most of the breakthrough reactions (84%) were mild. Sixteen patients had breakthrough reactions with multiple drugs. Although pyrazinamide was the most common culprit of breakthrough reactions and had the lowest desensitization success, it had the highest rate of a single breakthrough reaction (p < 0.001). Timing of the initial reaction and concomitant breakthrough reaction with ethambutol were found to have increased the risk for breakthrough reaction caused by rifampicin (p = 0.017 and p = 0.010 respectively). Conclusion: The rapid desensitization protocols used in this study provide a successful and effective management of the patients with a reaction phenotypically compatible with immediate-type drug hypersensitivity with first-line antituberculosis drugs.

Demographic and Asthma-Related Characteristics of Asthmatics Using Pressurized Metered Dose Inhalers and Dry Powder Inhalers.

Background: Asthma controller medications can be delivered via pressurized metered dose inhaler (pMDI) or dry powder inhaler (DPI) devices. Objective: This study aimed to evaluate the frequency of exacerbations and satisfaction rate with device use in asthmatics using pMDIs or DPIs. Methods: A multicenter, cross-sectional study was conducted in adults who used pMDIs or DPIs with correct inhaler technique and good adherence for asthma treatment. Demographic and asthma-related characteristics of the subjects and data regarding device satisfaction were collected through a face-to-face interview in the outpatient clinic. Rates of pMDI and DPI users and the data were compared between the two groups. Results: The study included 338 patients (mean age: 48.6 ± 14.5 years, 253 [74.9%] women). Among participants, 96 (28.4%) were using pMDI and 242 (71.6%) were using DPI. The age of patients using pMDI were significantly lower compared with DPI users. No significant difference was observed in terms of device satisfaction and clinical outcomes of asthma between pMDI and DPI users with good inhaler technique and good adherence. Conclusion: More asthmatics use DPIs, however, pMDIs are used in younger asthmatic patients. No significant difference in terms of device satisfaction and clinical outcomes of asthma was observed between pMDI and DPI users.

Is YouTube useful as a source of information for approaches to reducing blood pressure and hypertension treatment?

Hypertension is an important public health problem due to its high prevalence and common complications. The aim of this study was to evaluate the quality of videos on YouTube related to reducing blood pressure and hypertension treatment. Using the six search terms "hypertension treatment", "cure hypertension", "hypertension medication", "control high blood pressure", "lower high blood pressure", and "reduce high blood pressure", a total of 360 relevant videos on YouTube were evaluated. Some parameters, i.e., the length of the video, number of days on YouTube, number of view counts, and number of likes, dislikes, and comments, were noted for all videos. The Global Quality Scale (GQS) was used to evaluate the quality of the videos. We categorized the video content as useful or misleading using the evidence-based medical literature. After exclusions, 104 videos were evaluated by two independent reviewers. Out of all the videos, 51% were useful, and 49% were misleading. Videos mentioned lifestyle changes (LCs) more (65 videos, 62.5%), and only 39.4% (41 videos) of all the videos contained information about pharmacological treatment (PT). Videos about alternative treatment (AT) had high numbers of views, and videos about PT had low numbers of views, and this difference was statistically significant. Videos that did not include PT but did include LCs and AT had more likes, similar to the number of views.

Characteristics of adverse reactions due to subcutaneous allergen immunotherapy applied between 2011-2021: Single center experience.

Introduction: The aim of this study was to elucidate the incidence of local, large local and systemic reactions after subcutaneus immunotherapy (SCIT) injections in our clinic and to determine the characteristic features of these adverse reactions. Materials and Methods: A total of 6000 SCIT injections administered to 163 patients between January 2011 and December 2021 were retrospectively evaluated. The study population consisted of patients with allergic rhinoconjunctivitis who underwent SCIT due to pollen, house dust mite or cat allergy, or patients who underwent SCIT due to venom allergy. Demographic characteristics of the patients, diagnoses, allergen sensitivities, immunotherapy protocol applied, adverse reactions, and the characteristics of these reactions were recorded. Result: Totally, 163 patients with a mean age of 36.8 ± 12.7 years were enrolled in this research. Sex distribution was as follows: 55.2% (n= 90) were females. During the study, 218 allergic reactions were detected in 83 patients. The incidence of adverse reactions per injection was 3.6%. The probability of developing an adverse reaction in a patient during the entire subcutaneous immunotherapy was 53.9%. Of the adverse reactions that developed, 94 (43.1%, n= 47) were observed locally while 56 (25.7%, n= 40) were large local reactions, and 68 (31.2%, n= 30) were systemic. Incidence of adverse reactions per injection were 1.5%, 0.9%, and 1.1% for local reaction, large local reaction, and systemic reaction, respectively. Conclusions: The results of this analysis elaborated that subcutaneous immunotherapy is a safe and tolerable treatment modality. However, before initiating treatment, the benefits and risks should be evaluated. The risk of systemic reactions is quite low, but fatal anaphylaxis can occur, so physicians need to be aware of the potential risks.
