FCGR polymorphisms had been associated with the susceptibility and severity of various infections. FCGR2A 131R/R had been reported to attribute to the susceptibility of meningococcal infection, community-acquired pneumonia (CAP) caused by Haemophilus influenza, and the development of severe malaria [10] [11] [12] . FCGR2A 131H/H was reported to contribute to higher risk of bacteremia in pneumococcal CAP patients [13] . Another study showed that HIV-infected patients with FCGR2A 131R/R genotype progressed to a low CD4 + cell count at a faster rate, but conversely in individuals carried FCGR2A 131H/H there was an increased risk of Pneumocystis jiroveci pneumonia [14] . FCGR3A 158F/V gene polymorphism was not associated with progression of HIV infection, but predicted the risk of Kaposi's sarcoma [14] . A study on infections during induction chemotherapy found that FCGR2A 131H/H was associated with a decreased risk of pneumonia, FCGR3B NA1/NA1 associated with infections, and FCGR3A polymorphisms not associated with infections [15] . Sadki et al. investigated the influence of FCGR3A 158V/F and FCGR2A 131H/R polymorphisms on susceptibility to pulmonary tuberculosis in the Moroccan population but no association was found [16] . A study in East Africa found that the FCGR2B 232T/T genotype provided protectiveness for children against severe malaria [17] .
