Bortezomib Prescription Pattern for the Treatment of Multiple Myeloma by Hematologists in Nigeria.

PURPOSE: Novel therapy has dramatically changed the outcome of patients with myeloma. Current National Comprehensive Cancer Network guidelines give bortezomib-based combinations a central role in the management of multiple myeloma (MM). The aim of this survey is to assess the use of bortezomib for the treatment of MM by hematologists practicing in Nigeria. MATERIALS AND METHODS: This is a cross-sectional observational survey. A structured, prevalidated questionnaire was self-administered to different cadres of hematologists. Data collected were analyzed using SPSS software version 21 (IBM, Chicago, IL). RESULTS: There were 54 respondents from 24 centers across the country. The most frequently used drugs for first-line therapy were thalidomide (66.7%), dexamethasone (54.2%), and bortezomib (48%), and a combination of bortezomib, thalidomide, and dexamethasone (16.7%) was the most frequently used first-line regimen. Of the 54 hematologists, 39 (72.2%) had prescribed bortezomib previously; no one had used bortezomib as monotherapy. Drug unavailability (86.7%) and cost (46.7%) were the major reasons for those who had not prescribed bortezomib. Approximately 56.4% of responders had patients who had experienced adverse effects, of which neuropathy was the most common (86.3%). CONCLUSION: Bortezomib, thalidomide, and dexamethasone was the most frequently used first-line regimen to treat myelomatosis. Thalidomide and dexamethasone were the most frequently used drugs in myeloma treatment. Despite poor access to health care, coupled with the high cost and poor availability of bortezomib in our low- or middle-income country, those who prescribed bortezomib did so frequently (in more than half of their patients).

Blood transfusion services for patients with sickle cell disease in Nigeria.

BACKGROUND: Safe, timely red blood cell transfusion saves lives and chronic transfusion therapy (CTT) prevents or limits morbidities such as stroke, therefore improving quality of life of patients with sickle cell disease (SCD). METHODS: This questionnaire-based study assessed the ability of sickle cell centers in Nigeria to provide safe blood to patients with SCD between March and August 2014. RESULTS: Out of the 73 hospitals contacted, responses were obtained from 31. Twenty four (78%) hospitals were unable to transfuse patients regularly due to blood scarcity. Packed red blood cells were available in 14 (45%), while only one provided leukocyte-depletion. Most centers assessed donor risk and screened for HIV in 30 (97%), hepatitis B in 31(100%) and hepatitis C in 27 (87%) hospitals. Extended phenotyping and alloantibody screening were not available in any center. A quarter of the hospitals could monitor iron overload, but only using serum ferritin. Access to iron chelators was limited and expensive. Seventeen (55%) tertiary hospitals offered CTT by top-up or manual exchange transfusion; previous stroke was the most common indication. CONCLUSION: Current efforts of Nigerian public hospitals to provide safe blood and CTT fall short of best practice. Provision of apheresis machines, improvement of voluntary non-remunerated donor drive, screening for red cell antigens and antibodies, and availability of iron chelators would significantly improve SCD care in Nigeria.
