ABSTRACT
Background and objectives: Non-communicable diseases (NCDs) are highly prevalent in the tribal populations; however, there are limited data regarding health system preparedness to tackle NCDs among these populations. We estimated the availability of human resources, equipment, drugs, services and knowledge of doctors for NCD management in the selected tribal districts in India. Methods: A cross-sectional survey was conducted in 12 districts (one from each State) with at least 50 per cent tribal population in Andaman and Nicobar Islands, Himachal Pradesh, Madhya Pradesh, Odisha and eight northeastern States. Primary health centres (PHCs), community health centres (CHCs) and district/sub-district hospitals (DHs) were surveyed and data on screening and treatment services, human resources, equipment, drugs and information systems indicators were collected and analysed. The data were presented as proportions.Results: In the present study 177 facilities were surveyed, including 156 PHCs/CHCs and 21 DHs. DHs and the majority (82-96%) of the PHCs/CHCs provided outpatient treatment for diabetes and hypertension. Overall, 97 per cent of PHCs/CHCs had doctors, and 78 per cent had staff nurses. The availability of digital blood pressure monitors ranged from 35 to 43 per cent, and drugs were either not available or inadequate. Among 213 doctors, three-fourths knew the correct criteria for hypertension diagnosis, and a few correctly reported diabetes diagnosis criteria. Interpretation & conclusions: The results of this study suggest that the health system of the studied tribal districts was not adequately prepared to manage NCDs. The key challenges included inadequately trained workforce and a lack of equipment and drugs. It is suggested that capacity building and, procurement and distribution of equipment, drugs and information systems to track NCD patients should be the key focus areas of national programmes
ABSTRACT
Background & objectives: Non-communicable diseases (NCDs) are the leading cause of death in India. Although studies have reported a high prevalence of NCD in tribal populations, there are limited data pertaining mortality due to NCDs. Therefore, in this study we estimated the proportion of deaths due to NCDs among 15 yr and older age group in tribal districts in India. Methods: We conducted a community-based survey in 12 districts (one per State) with more than 50 per cent tribal population. Data were collected using a verbal autopsy tool from the family member of the deceased. The estimated sample size was 452 deaths per district. We obtained the list of deaths for the reference period of one year and updated it during the survey. The cause of death was assigned using the International Classification of Diseases-10 classification and analyzed the proportions of causes of death. The age-standardized death rate (ASRD) was also estimated. Results: We surveyed 5292 deaths among those above 15 years of age. Overall, NCDs accounted for 66 per cent of the deaths, followed by infectious diseases (15%) and injuries (11%). Cardiovascular diseases were the leading cause of death in 10 of the 12 sites. In East Garo Hills (18%) and Lunglei (26%), neoplasms were the leading cause of death. ASRD due to NCD ranged from 426 in Kinnaur to 756 per 100,000 in East Garo Hills. Interpretation & conclusions: The findings of this community-based survey suggested that NCDs were the leading cause of death among the tribal populations in India. It is hence suggested that control of NCDs should be one of the public health priorities for tribal districts in India.
ABSTRACT
Background: Though the natural history of Human Immunodeficiency Virus (HIV) infection in many patients has been dramatically altered through the use of antiretroviral therapy, this treatment paradigm of chronic chemotherapy may not be sustainable given the short and long-term toxicities of these medications. Currently, there is lack of data in the Indian literature regarding study of endothelial dysfunction in HIV patients. The purpose of our research was to study the effect of anti-retroviral therapy on the progression of endothelial dysfunction in HIV/AIDS patients.Methods: The study comprises a total number of 30 adult HIV positive patients of both sex with confirmed HIV seropositivity and CD 4+T cell count < 200/µl. None of these patients had ever received anti retroviral therapy (ART). These patients were subjected to detailed clinical examination and markers of endothelial dysfunction - Flow mediated vasodilatation (FMD) of brachial artery, S. Nitrite and C-reactive protein (CRP) were performed before starting ART. Study group patients were started on ART, they received triple drug ART (Lamivudine 150 mg BD, Stavudine 30 mg BD, Nevirapine 200 mg BD). In patients on ART after a period of 6 months, markers of endothelial dysfunction - FMD, S. Nitrite and CRP tests were reassessed.Results: FMD (4.08±3.58) and S. Nitrite (20.83±13.75) were also depressed after six months of anti retroviral therapy. Also, patients showed more CRP positivity and higher titres after ART. CD 4+T cell count before ART (124.16±84.46) and after ART (186.63±70.96). This rise in count was statistically significant.Conclusions: HIV patients who are receiving ART demonstrate a number of metabolic abnormalities with more severe depression in markers of endothelial function.
ABSTRACT
Background: Number of factors play a role in endothelial dysfunction observed in AIDS patients, which can lead to atherosclerosis along with cardiovascular mortality and morbidity. Human immunodeficiency virus (HIV), the etiologic agent of AIDS causes several vascular disorders characterized by an evident activation and perturbation of endothelial cells. Currently, there is lack of data in the Indian literature regarding study of endothelial dysfunction in HIV patients. The purpose of our research was to study the prevalence of endothelial dysfunction in HIV/AIDS patients.Methods: The study comprises a total number of 60 adult HIV positive patients of both sex (male and female) with confirmed HIV seropositivity. The patients were divided into two groups of 30 each, depending on the degree of immune dysfunction (CD 4 cell counts). Group I- patients with CD 4+T cell count>200/µl and group II-patients with CD 4+T cell count<200/µl. These patients were subjected to detailed clinical examination and markers of endothelial dysfunction-flow mediated vasodilatation (FMD) of brachial artery, S. nitrite and C-reactive protein (CRP) were performed.Results: The defect in endothelial function was most prevalent in patients with more severe immunosuppression. FMD of brachial artery was decreased in patients with CD 4+T cell count < 200/µl (7.07±2.89, p=0.00). S. nitrite was also significantly lower in group II patients (26.43±15.38), and these patients also showed more CRP positivity and higher CRP titres ranging from 1.2 mg/dl to 9.6 mg/dl.Conclusions: The defect in endothelial function was most prevalent in patients with more severe immunosuppression. FMD of brachial artery was decreased in patients with CD 4+T cell count <200/µl (7.07±2.89, p=0.00). S. nitrite was also significantly lower in group II patients (26.43±15.38), and these patients also showed more CRP positivity and higher CRP titres ranging from 1.2 mg/dl to 9.6 mg/dl.
