Isolated acquired factor VII deficiency is a rare coagulopathy. It has been reported in 31 patients with malignancy, sepsis, postoperatively, aplastic anemia, and during bone marrow transplantation. We discuss, through a new case of acquired factor VII deficiency, the characteristics of this disease when it is associated with acute myeloid leukemia. Acquired factor VII deficiency in hematological diseases can be caused by intensive chemotherapy, infections, or hepatic dysfunction. The best treatment in developing countries remains corticosteroids associated with plasma exchange, frozen plasma, and antibiotics.

Treatment of acute myeloblastic leukemia in children, adolescents and young adults (AYA) is a challenge in low-income countries. To evaluate treatment outcomes of children (B 15 years) and AYA (15-30 years) diagnosed with novo AML and treated in a single center according to the AML-MA 2011 protocol. From January 2011 to December 2015, eligible patients (age B 30 years) with novo AML had been enrolled on a uniform treatment protocol. The diagnosis was confirmed according to the FAB classification using the WHO 2008 criteria. Patients with WBC C 50 G/L had pretreated 4 days of hydroxyurea followed by two inductions and two consolidations. Supportive care consisted of transfusion of labile blood products, antibiotics and antifungals, and patient and family education by the hygiene team. 155 patients were recruited, 41 were \ 15 years old (22 boys, median age 7.8 years). Of the 114 AYA enrolled, (48 women, median age 23 years). Complete remission after two inductions was 28/41 (68.3%) of the children, including 100% of the children in the favorable group and 71/114 (62.3%) of the AYA, 22 of whom (68.7%) were in the favorable group. The number of deaths among children was 6 (14.6%). The evaluation of the AML-MA-2011 National Protocol in the age groups of children and AYA reveals that the objective of treatment is almost achieved in terms of complete remission in the two age groups.

AIM:The goals of this paper are: to report the incidence of AML in elderly, to describe cytogenetic characteristics of this population, to observe rare and novel cytogenetic abnormalities and lastly, to compare our finding with that previously reported in the literature.METHODS:We conducted a retrospective analysis of 283 patients with acute myeloid leukaemia (AML) treated in our unit, we will report the incidence of AML in elderly, describe cytogenetic characteristics of this population, observe rare and novel cytogenetic abnormalities and compare our finding with that previously reported in the literature.RESULTS:Among the 283 patients, 157 (54.4%) patients performed the karyotype, the cytogenetic analysis failed in 17 cases (11%). Prognostic group distribution was found to be favorable in 8 patients (6%) with 6 cases of t (8; 21) and 2 cases of inv (16), intermediate group in 94 patients (67%), including 58 cases (41,5%) with a normal karyotype, and an unfavorable group in 38 patients (27%) including complex karyotype (15%), -5 or del 5q (3%), -7 or del 7q (3.5%), t (9; 22) (2%). Some rare anomalies were observed.CONCLUSION:However, the occurrence of a complex karyotype was more frequent than younger patients. In our unit, elderly benefit from supportive care, our study shows that it is a heterogeneous group and our treatment approach have to change especially for the patient from favourable risk group who can benefit from intensive chemotherapy. We have to improve our diagnosis with including molecular genetics that provides a documented substrate for a thoughtfully considered treatment plan.
