RESUMO
OBJECTIVE: Immune thrombocytopenia (ITP) is an immune haematologic disorder causing platelet destruction mediated by anti-platelet antibodies. In this study we aimed to evaluate the clinical and laboratory variables of ITP patients in southeast of Turkey. METHODS: In this retrospective study 167 ITP patients between 2005 and 2015 were evaluated. All patients were screened for immunological parameters including ANA (antinuclear antibodies), anti dsDNA (anti-double-stranded-DNA), ACA(anti-cardiolipin) IgM and IgG, LA (lupus anticoagulants). All patients were screened for Helicobacter pylori, HBsAg (Hepatitis B surface antigen), anti-HCV (hepatitis C virus antibody), and anti-HIV ½ (HIV antibody) and brucellosis.. RESULTS: Among the patients, 50 (29.9%) patients were male, 117 (70.1%) were female. The age range of patients was 18-86 (mean 38.16±14). In 56 patients (33.5%) splenectomy was performed. 36 patients (21.6%) were positive for ANA, 5 (3%) were positive for anti dsDNA, 14 (8.4%) for ACA Ig G, and 14 (8.4%) patients for ACA IgM. LA was tested in 165 patients and 30 (18%) patients were positive for LA. Microbiologic evaluation was as follows: 16 patients (9.6%) were positive for HbsAg, 109 (65.3%) positive for Anti-HBs, 5 positive for anti-HCV (3%), 56 (33.5%) patients were positive for Helicobacter pylori antigen, 5 (2.9%) for Brucella and one patient was positive for anti-HIV ½. CONCLUSIONS: Immune thrombocytopenia patients have to be evaluated according to their demographic characteristics and laboratory results. Secondary causes of ITP were HIV, HCV, Helicobacter pylori, brucellosis, tuberculosis, and autoimmune diseases in our region. Management of ITP patients can change in different regions.
