Immune thrombocytopenia (ITP) is the most common cause of thrombocytopenia in children. This
retrospective study was designed to analyze presenting features of ITP cases in Benha, evaluate outcomes
in children and determine prognostic factors. This research was accepted by Research Ethics
Committee (REC) of Faculty of Medicine, Benha University (chairman: Prof. Nermeen Adly Mahmoud).
Ethics comittee refrence number MS 40-3/2019. Records of 308 children with ITP in Benha University
Hospitals and Benha Children Hospital haematology clinics between May 2014 and January 2021
were retrospectively analyzed. Socio-demographic, clinical, and laboratory data of the studied children
such as age, gender, the type of residence, the date of diagnosis, complaints at presentation,
preceding vaccination or infection, the type of bleeding, initial platelet count, LDH (lactate dehydrogenase)
level, initial treatment, and outcomes were recorded. A total of 308 children diagnosed with
ITP were included, clinical courses were determined as newly diagnosed and chronic in 71.4% and
28.6%, respectively. The median age of patients at diagnosis was 5 ± 3.4 years. The male/female ratio
was 1.14. The median age at diagnosis was significantly higher in chronic ITP patients (p < 0.001);
patients ≥ 10 years were more likely to develop chronic ITP than younger ones (p = 0.029). Regarding
residency, seasonality, type of bleeding and history of preceding infection or vaccination, the difference
was not statistically significant. Initial platelet counts > 20 × 109 were significantly more prevalent
in chronic ITP (p < 0.001). LDH level at presentation was significantly higher in chronic cases
(p = 0.046). Initial lines of treatment were the following: steroids, IVIG, and IVIG with steroids (in 88%,
5.2%, and 2.9% of the cases, respectively). A total of 3.9% of the children did not receive any treatment.
There was no significant difference in the outcomes between the initial lines of treatment
(p = 0.105). In our study, age > 10 years, female gender, higher platelet count and high LDH level at
presentation were found to increase the probability of chronic ITP. |
