Abstract:
BACKGROUND
Sickle  cell  anaemia(SCA)is  a  genetic  disorder  of  haemoglobin  and chronic inflammatory state. This study aimedto determine and compareC -reactiveprotein(CRP)levels and bloodcounts in participants with SCA(HbSS) andcontrol (HbAS and HbAA).
MATERIALS AND METHODS
Across-sectional  comparative  studywas carried  outamong steady-state HbSSindividuals with age-and sex-matched controlfrom August 2019 to February  2020. Using the method described by Charan and Biswasand sickle  cell disease  prevalence of 3.5%,a sample  size  of 47was  calculated.  However,  101participants  were  recruited  using  a consecutivesampling technique.An assay of haemoglobin phenotype, CRPleveland some haematological parameters, including haemoglobin level, white blood cell count and platelet count, were done. Data analysis was done usingSPSS software, version 26.
RESULTS
One  hundred  and  onesubjectsparticipatedinthe  study  and  were  made  up  of51 (50.5%) males and 50 (49.5%) females with an age range of 1 to 52 years. They comprised 58HbSS and 43 controls (23 HbAS and 20 HbAA).There was a significant increase in CRPlevel  among HbSS participants(5.4μg/ml±4.5)compared  to  those  of  HbAS(0.02μg/ml  ± 0.01)and HbAA(0.02μg/ml ± 0.01) (p = 0.000). Correlation between CRP level and blood counts showed weak positive relationship between CRP and WBC count (r = 0.285, P = 0.07)as  well  as  platelet  count  (r =  0.156, P =  0.336)  butnegative  correlation  between  CRP  and haemoglobin level(r = -0.073, P = 0.655).
CONCLUSION
There was  a  significantly  higher  CRP  levelamong  patients  with HbSS in  a steady state compared to control (HbAS and HbAA individuals).
Participants with HbSShada positivebut weakrelationshipbetween CRP and WBC count,  CRP  and  plateletcount  anda  weak  negative correlation  between  CRP  and haemoglobin level. Further studies are required on a broader scale to assess whether CRPlevelmaybe used to predict the occurrence of crisisin patients with SCA.
