Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and cyclosporine A (CsA) is the first-line therapy for acquired aplastic anemia (AA) in those not suitable for bone marrow transplant. Horse ATG (hATG) is preferred for this purpose, but its use is often impeded by shortages and costs. Being a rare disease, there is limited data on this therapy. This study aimed to evaluate this therapy in a large cohort of AA patients from western India. We retrospectively analyzed AA patients who received an indigenous preparation of hATG along with CsA as first-line treatment, between 2012 and 2015, at our center and evaluated the response, survival, and occurrence of adverse events. The response was further assessed separately for adults and children. During the period, 91 AA patients (4 non-severe, 57 severe and 30 very severe) were treated with IST. At 2 years, 23.5% adults and 39.1% children showed complete response and an overall of 68.1% cases became transfusion independent. More than half of the patients developed febrile neutropenia while roughly one sixth of the patients developed gum hypertrophy and/or hypertension. Two patients had clonal evolution. Mortality rate was calculated to be 31%; most common causes of death were infection and intracranial hemorrhage. The results of the study substantiate the effectiveness of IST in AA, using an inexpensive indigenous preparation of hATG along with CsA. [ABSTRACT FROM AUTHOR]

An experiment was made to identify the lymphoid cells by the use of indirect immunofluorescent staining with rabbit antiserum prepared against P3-J lymphoblastoid cells of Burkitt origin. Cultured lymphoblastoid cell line P3-J, Raji, RPMI #8226 and RPMI #4666 were stained positively with this antiserum. Nonlymphoid cell line RPMI #41 was negative for the staining. Lymphatic cells of stamped preparations from human lymph nodes were also positive for the staining. When human peripheral white cell smears were tested, only lymphocytic cells were positively stained. [ABSTRACT FROM AUTHOR]
