ABSTRACT
Introduction: Spondyloarthropathies are a heterogeneousgroup of inflammatory interrelated diseases involvingperipheral joints and spine. All forms of spondyloarthropathiesare known to have a strong association with HLA-B27 gene invarious studies done. There was a paucity of literature aboutclinical and demographic characteristics of the HLA-B27positive arthritis patients in Rajasthan. So this study wasplanned to know the seropositivity of HLA-B27 amongseronegative spondyloarthritis patients and to find outassociation between socio-demographic and clinicalcharacteristics and HLA-B27 seroprevalence.Materials and Methods: A cross sectional observational studywas carried out from May 2017 to April 2018 in Department ofPathology, SMS Medical College, Jaipur (Rajasthan). A total of100 cases of spondyloarthritis disease were enrolled in thestudy to find out seroprevalence of HLA-B27 and todifferentiate the clinical and demographic characteristics inHLA-B27 positive and negative patients.Results: In the present study 29% seroprevalence of HLA-B27was observed. Seropositivity of HLA-B27 was significantlyassociated with age (P-value < 0.05) while sex, religion, caste,family history, raised ESR, Positive C-reactive protein, RAfactor etc. were showed no significant association (P-value >0.05).Conclusion: This study confirms the previously reportedassociation in ankylosing spondylitis patients between HLAB27 and earlier disease onset with male preponderance &family aggregation.
ABSTRACT
Background: Congenital B-cell Acute lymphoblastic leukemia (ALL) is a rare malignancy.Case Characteristics: A newborn infant presented with purpuric spots and ecchymoticpatches, blueberry muffin rash, depressed neonatal reflexes, respiratory distress andhepatosplenomegaly. Peripheral smear revealed atypical blast cells. Serum ELISA waspositive for Rubella IgM and IgG antibodies. Flow cytometry suggested congenital B-cellALL. Outcome: The baby died after 3 days due to suspected intracranial hemorrhage.Message: Congenital leukemia may be rarely associated with congenital rubella infection.
