In this study, we aimed to evaluate the pattern of lung impairment using various pulmonary tests and the effects of transfusion on pulmonary functions in patients with TM. <b><i>Materials and Methods:</i></b> The study was performed on patients 9-21 years of age prospectively. Spirometric tests, plethysmography, and CO diffusion tests were performed before and 2 h after erythrocyte transfusion. Patients also underwent a methacholine stimulation test 2 h after transfusion. <b><i>Results:</i></b> A total of 37 patients with TM were included in the study. There was no change in pretransfusion and post-transfusion spirometric test results. Plethysmographic tests revealed that both the median total lung capacity and the mean vital capacity values have decreased after transfusion. Medians of pretransfusion DLCO values significantly increased after transfusion. There was an impairment in diffusion in 16 (44.4%) patients, whereas it improved in 9 patients after transfusion. Bronchial hyperreactivity was detected in 10 out of 27 patients (37%) via methacholine stimulation test. There was obstructive airway disease in 20 patients (54%) out of 37 patients who had been tested. <b><i>Conclusions:</i></b> Patients with TM may have respiratory function abnormalities even while being asymptomatic. An obstructive airway pattern was the most common abnormality in our patient group.

Defects in the IL-10 signaling pathway, including mutations in interlaukin-10 receptor (IL-10R) beta, have been implicated in early-onset inflammatory bowel disease (IBD), often resistant to conventional treatments. <b><i>Case Presentation:</i></b> We report a 1.5-month-old male patient with IL-10R beta deficiency presenting with fever, vomiting, malnutrition, and sepsis. Despite normal initial evaluations, persistent fever and elevated inflammatory markers prompted the initiation of anakinra, an interleukin-1 receptor antagonist. Genetic testing confirmed a homozygous deletion in the <i>IL10RB</i> gene. Anakinra led to significant clinical improvement, including weight gain and symptom resolution. The patient was enrolled in an allogeneic hematopoietic stem cell transplantation (HSCT) program and successfully received HSCT from an HLA-matched related donor. <b><i>Discussion:</i></b> IL-10R beta deficiency presents with severe and early-onset symptoms, often unresponsive to standard IBD therapies. Anakinra has shown promise in bridging to HSCT by reducing inflammation and improving clinical outcomes in patients with IL-10 pathway defects. This case highlights the effectiveness of anakinra as a treatment strategy in severe, refractory IBD associated with IL-10R beta deficiency and underscores the importance of genetic testing for accurate diagnosis and treatment planning. <b><i>Conclusion:</i></b> Anakinra may provide significant clinical benefits in patients with IL-10R beta deficiency, serving as a bridge to definitive treatment with HSCT.
