Cerebral Venous Sinus Thrombosis due to Iron Deficiency Anemia in an Adolescent Girl.

Cerebral venous sinus thrombosis (CVST) is rare but now increasingly diagnosed in children. Early diagnosis is of prime importance as any delay leads to significant mortality and morbidity. It requires a high index of suspicion to diagnose CVST early as, often, the symptoms are vague and the signs are nonspecific.

Haploidentical Stem Cell Transplantation With Post-transplant Cyclophosphamide for Pediatric Acute Leukemia is Safe and Effective.

Background: Haploidentical family donor is universally available and is fast emerging as an alternative donor choice for children with leukemia needing hematopoietic stem cell transplant (HSCT). Here we describe our experience of treating children with acute leukemia by haploidentical HSCT with posttransplant cyclophosphamide (PTCy).

Methods: We retrospectively analyzed the outcome data of 17 children with acute leukemia who underwent related haploidentical HSCT.

Successful Haploidentical Stem Cell Transplant With Posttransplant Cyclophosphamide for Hemophagocytic Lymphohistiocytosis.

Allogeneic hematopoietic stem cell transplant (HSCT) has been known to be a curative therapy for patients with hemophagocytic lymphohistiocytosis (HLH) but donor availability is an issue. Haploidentical HSCT with posttransplant cyclophosphamide (PTCy) has been investigated as a feasible option for various malignant and nonmalignant conditions with reduced incidence of acute graft versus host disease (GVHD) and graft rejection. However, its use has not been described in children with HLH and here we describe 2 boys who underwent successful haploidentical HSCT with PTCy.

Successful Nonmyeloablative Allogeneic Stem Cell Transplant in a Child With Emberger Syndrome and GATA2 Mutation.

Emberger syndrome with underlying guanine-adenine-thymine-adenine 2 (GATA2) mutation is a rare disorder and very few successful nonmyeloablative allogeneic hematopoietic stem cell transplants (HSCTs) have been reported. We report a case of Emberger syndrome with GATA2 mutation in a 9-year-old girl who presented with congenital sensorineural deafness, warts, lymphedema, and Myelodysplastic syndrome. Her sister had died of a similar illness.

Reduced-toxicity alternate-donor stem cell transplantation with posttransplant cyclophosphamide for primary immunodeficiency disorders.

We describe here the outcomes of reduced-toxicity alternate-donor stem cell transplant (SCT) with posttransplant cyclophosphamide (PTCy) for primary immunodeficiency disorders (PIDs) in eight children (haploidentical-seven and matched unrelated donor-one). The conditioning was with serotherapy (alemtuzumab-3/rabbit-anti-thymoglobulin-5); fludarabine, cyclophosphamide, and total body irradiation-5 (additional thiotepa-3); fludarabine and treosulfan-2; and fludarabine and busulfan-1. All received PTCy 50 mg/kg on days 3 and 4 as graft versus host disease prophylaxis along with tacrolimus and mycophenolate.

Successful Reduced Intensity Conditioning Alternate Donor Stem Cell Transplant for Wiskott-Aldrich Syndrome.

There are very few reports of reduced intensity conditioning (RIC) hematopoietic stem cell transplant (HSCT) with alternate donor for Wiskott-Aldrich syndrome (WAS) and there is no report of RIC with posttransplant cyclophosphamide (PTCy) in WAS. There is only 1 report of T cell receptor αβ and CD19-depleted haploidentical HSCT for WAS. Here we report successful outcome in 3 children with WAS who underwent successful RIC alternate donor HSCT of whom 2 (matched unrelated donor and T-cell replete haploidentical) received PTCy and 1 underwent T cell receptor αβ and CD19-depleted haploidentical HSCT.
