Occurrence of asymptomatic microscopic haematuria in a filarial endemic area of Orissa, India.
To determine the frequency of occurrence of asymptomatic microscopic haematuria in filarial endemic area of Orissa, where the mf rate and disease rate were observed to be 14.8% and 37.2% respectively, clinical examination, night blood smear examination, morning midstream urine examination were conducted on 697 persons-randomly selected from all age groups in 8 villages of Puri tehsil. Out of them, 15.6% were found to have asymptomatic haematuria (Grade I-14.7%, Grade II-0.6%, Grade-III 0.3%). The prevalence of asymptomatic microscopic haematuria was observed to have positive statistical correlation with mf status (P < 0.001), filarial antigenaemia (Ag) (P < 0.001), antibody (Ab) (P < 0.001) and circulating immunocomplex antigen (CIC-Ag) (P < 0.001). The prevalence was also found to be increased with the progression of the disease process i.e. from endemic normal to chronic manifestations. None of the cases having Grade-II and III haematuria cases revealed any gross renal pathological lesions, when subjected to special investigations like X-ray, IVP, cystoscopy and urethroscopy.
