A Tagging Polymorphism in Fat Mass and Obesity-Associated (FTO) Gene Is Associated with Sepsis Status in Children.

INTRODUCTION: Sepsis is one of the most common causes of death in patients admitted to intensive care units (ICUs). The development of sepsis is significantly influenced by genetic predisposition. In this study, we highlight a potential association between a variant of the fat mass and obesity-associated (FTO) gene and risk of sepsis in children and adolescents. METHODS: We investigated a first-intron tagging FTO polymorphism (rs17817449) by comparing a severe condition (SC) group, comprising 598 paediatric patients (ages 0-19 years) admitted to an ICU with fever, systemic inflammatory response syndrome (SIRS), sepsis, severe sepsis, septic shock, or multiple organ dysfunction syndrome (MODS), with a control group consisting of 616 healthy young adults. RESULTS: We observed a lower prevalence (p < 0.01; OR = 0.59, 95% CI = 0.39-0.87) of the FTO TT genotype in febrile and SIRS patients compared to patients with severe illness. There was a borderline trend towards a lower prevalence of the FTO TT genotype in the control group compared to the SC group (p < 0.09, OR = 0.81, 95% CI = 0.62-1.06). CONCLUSIONS: Our findings suggest that rs17817449, a common FTO polymorphism, may be a predictor of sepsis in paediatric patients, and that higher body weight is protective against this clinical complication.

Unvaccinated child tetanus from nasal toy battery.

We present the case report of an unvaccinated Czech child with tetanus. The child had not received any vaccines due to its parent's refusal. The disease originated from the wound in the nose caused by a small flat battery. The typical onset of tetanus followed after two weeks, rapidly progressing to respiratory failure with the need for mechanic ventilation despite intensive treatment. The child spent five weeks in the hospital. Mild long-term sequelae persisted 5 months.
