Severe Congenital Neutropenia (SCN) is a rare inherited disease characterized by an absolute neutrophil count (ANC) lower than 500/μL. Genetic heterogeneity and biallelic CSF3R mutation has rarely been identified as an underlying genetic defect in SCN. The majority of SCN patients respond to granulocyte colony stimulating factor treatment; however, in patients with inherited CSF3R mutation, ANC cannot generally be increased with granulocyte colony stimulating factor treatment. In such cases, granulocyte macrophage colony stimulating factor presents as an effective treatment option. Herein, we report a case of a 5-year-old SCN girl with homozygous c610-611 del ins AG (p.Q204R) mutation in the CSF3R gene, who was successfully treated with granulocyte macrophage colony stimulating factor.

Background and Aim: Neutrophil gelatinase–associated lipocalin (NGAL) is found in the granules of human neutrophils, with many diverse functions. Expression of NGAL is induced under various pathophysiological conditions, for example, infection, inflammation, kidney injury, cardiovascular disease, burn injury, and intoxication, and it has an important antiapoptotic and anti-inflammatory role. Patients and Methods: A total of 37 patients with thalassemia disease β-thalassemia major (24 male and 13 female individuals) and 37 healthy controls (17 male and 20 female) were enrolled in this study. All patients were regularly transfused, and all of them were using oral chelator, deferasirox. Results: NGAL and cystatin C levels were significantly higher in the case group than in the control group. Conclusion: In patients with β-thalassemia major, renal damage can occur owing to regular blood transfusion. Urinary NGAL levels in these patients may be considered as a marker for early renal injury.

Congenital neutropenia (CN) is a rare disorder, and the most common gene responsible for CN is ELANE. Furthermore, the mutations of HAX1, G6PC3, and JAGN1 genes may cause CN. These patients generally find great benefit from subcutaneous administration of Granulocyte Colony Stimulating Factor (GCSF). In recent years, Biallelic Colony Stimulating Factor 3 Receptor (CSF3R) mutations have been described as an underlying defect of CN in several children. In contrast to the previous group, the patients who have a CSF3R mutation do not respond to GCSF treatment. Here, we present a CN patient with hypomorphic biallelic CSF3R mutation responding to GCSF.

Objective To investigate the effect of inflammation on the conducting system of the heart in patients diagnosed with brucellosis. Methods A total of 42 patients diagnosed with brucellosis and 39 age and sex-matched healthy children were enrolled into the study. Pre- and post-treatment electrocardiographic parameters in brucellosis and control group were recorded from an electrocardiogram for each patient. Results The results indicated that the parameters including Pmax, Pdis, QTmax, QTdis, QTcdis, Tp-edis interval and Tp-emax/QTmax and Tp-emax/QTcmax ratios, which are known to be key indicators for the prediction of severe atrial or ventricular arrhythmia and sudden cardiac death and also important parameters used as the indicators for the non-invasive evaluation of the transmural heterogeneity were significantly longer in the study group compared with the control group (p < 0.05). Conclusion In this study, it was determined that the brucella disease had more cardiac involvement than thought, and this was more in the subclinical form of cardiac involvement.

Typhoid fever is an acute and systemic infectious disease that is specific to humans and is caused by Salmonella typhi. Patients may present with different findings ranging from simple fever to multiple organ failure. Hemophagocytosis and rhabdomyolysis are rare complications of typhoid fever. In this study, we presented a case of hemophagocytic lymphohistiocytosis and rhabdomyolysis in a 14-year-old girl who migrated from Mosul, Iraq, 1 month ago.
