Primary human parvovirus B19 infection in an HIV infected patient on antiretroviral therapy.

INTRODUCTION: Persons with HIV infection frequently present with anaemia from different causes, including use of antiretroviral therapy (typically zidovudine), iron deficiency, vitamin B12 deficiency, opportunistic infections (such as mycobacterial and fungal infections), chronic disease, AIDS-associated malignancies, autoimmune haemolysis, and direct effects of HIV infection itself. Persistent infection with Parvovirus B19 (B19) is an important treatable cause of anaemia in HIV-infected patients. CASE PRESENTATION: We present a case of anaemia in HIV positive patient who did not respond to change of drug therapy and nutritional supplements. Bone marrow biopsy suggested parvo virus infection. CONCLUSIONS: Chronic anaemia due to Parvo virus B19 infection is a treatable cause. Human Parvo virus B19 infection is a diagnosis of exclusion in patients who are started on antiretroviral therapy develop anaemia and later not responding to empirical management. Chronic anaemia requiring recurrent transfusions in HIV positive patient Parvo virus infection should be suspected and evaluated.

Assessment of the impact of heart failure on household economic well-being: a protocol.

Background: Heart failure (HF), which is an emerging public health issue, adversely affects the strained health system in India. The adverse impact of HF on the economic well-being has been narrated in various anecdotal reports from India, with affected individuals and their dependents pushed into the vicious cycle of poverty. There is limited research quantifying how HF impacts the economic well-being of households from low- and middle-income countries. Methods: We describe the methods of a detailed economic impact assessment of HF at the household level in India. The study will be initiated across 20 hospitals in India, which are part of the National heart Failure Registry (NHFR). The selected centres represent different regions in India, stratified based on the prevailing stages of epidemiological transition levels (ETLs). We will collect data from 1800 patients with acute decompensated HF and within 6-15 months follow-up from the time of initial admission. The data that we intend to collect will consist of a) household healthcare expenditure including out-of-pocket expenditure, b) financing mechanisms used by households and (c) the impoverishing effects of health expenditures including distress financing and catastrophic health expenditure. Trained staff at each centre will collect data by using a validated and structured interview schedule. The study will have 80% power to detect an 8% difference in the proportion of households experiencing catastrophic health expenditures between two ETL groups.  After considering a non-response rate of 5%, the target sample size is approximately 600 patients from each group and the total sample size is 1800 patients. Potential Impact: Our study will provide information on catastrophic health spending, distress financing and household expenditure in heart failure patients. Our findings will help policy makers in understanding the micro-economic impact of HF in India and aid in allocation of appropriate resources for prevention and control of HF.
