Introduction:The HIV epidemic has posed major, almost insurmountable, challenges to tuberculosis control efforts across the world. This study analyzes the prevalence and disease profile of HIV/AIDS coinfection in Vadodara, Gujarat, India.Materials and Methods:This study was conducted in the HIV Referral Clinic at Vadodara, India. Using convenience sampling method, 246 HIV-positive patients coinfected with tuberculosis were enrolled. A detailed history of every case was taken followed by a thorough physical examination. Baseline and follow up laboratory and radiological investigations were carried out as appropriately warranted.Results:Out of 500 HIV positive patients who presented to the clinic during the study period, 246 (49.2%) were coinfected with tuberculosis. Out of 246 coinfected cases, 35(14.2%) presented with demonstrable and documented tuberculosis whereas in 211(85.8%) cases, tuberculosis was extemporaneously detected by actively screening the patients. Sixty nine percent of patients were males, while 10.5% of cases were below fifteen years of age. The majority (68%) of patients had manifestations of extrapulmonary tuberculosis; but pulmonary tuberculosis, which is a more common presentation in HIV-negative cases, was present in only fifty five percent of this segment of the population. Abdominal tuberculosis was the most common site (74%) amongst extrapulmonary tuberculosis involvement, followed by clinically palpable lymph nodes (22%) and pleural effusion (17%).Conclusion:The prevalence of tuberculosis in HIV-positive patients in this study (49%) was substantially higher than that reported in previous studies. However, this could be attributed to a selection and/or a diagnosis bias. This study used abdominal ultrasound for the diagnosis of tuberculosis which might have obviously increased the prevalence. Moreover, these cases were not confirmed by biopsy or other definitive TB diagnostic methods.
It is interesting to study an autoimmune condition like dermatomyositis (DM) in the setting of immunosuppression due to human immunodeficiency virus (HIV) infection. An HIV seropositive female aged 30 years, presented with a nonitchy rash over the face, breathlessness, diarrhoea and difficulty in raising her hands above her head. A heliotrope rash around the eyes, Gottron's papules and proximal muscle weakness were found to be present. C reactive protein, erythrocyte sedimentation rate and lactate dehydrogenase levels were raised, but creatinine phosphokinase and anti-nuclear antibody profile were normal. Her HIV serostatus was confirmed by Western blotting, keeping in mind the potential for false positive HIV serology in an autoimmune disorder. Her CD4 count was 379 cells/mm3. An X-ray of the chest showed bilateral pleural effusion with raised pleural fluid adenosine deaminase levels. Clinical findings and laboratory investigations favored the diagnosis of DM and HIV infection with tuberculous effusion in an HIV seropositive patient. She was treated with antibiotics, four-drug anti-tubercular treatment, systemic steroids and later, antiretroviral treatment. Chances of a false positive antibody test for HIV should be considered in a patient having an autoimmune disease such as DM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
