Strong association between serological status and probability of progression to clinical visceral leishmaniasis in prospective cohort studies in India and Nepal.

Introduction Asymptomatic persons infected with the parasites causing visceral leishmaniasis (VL) usually outnumber clinically apparent cases by a ratio of 4–10 to 1. We assessed the risk of progression from infection to disease as a function of DAT and rK39 serological titers. Methods We used available data on four cohorts from villages in India and Nepal that are highly endemic for Leishmania donovani. In each cohort two serosurveys had been conducted. Based on results of initial surveys, subjects were classified as seronegative, moderately seropositive or strongly seropositive using both DAT and rK39. Based on the combination of first and second survey results we identified seroconvertors for both markers. Seroconvertors were subdivided in high and low titer convertors. Subjects were followed up for at least one year following the second survey. Incident VL cases were recorded and verified. Results We assessed a total of 32,529 enrolled subjects, for a total follow-up time of 72,169 person years. Altogether 235 incident VL cases were documented. The probability of progression to disease was strongly associated with initial serostatus and with seroconversion; this was particularly the case for those with high titers and most prominently among seroconvertors. For high titer DAT convertors the hazard ratio reached as high as 97.4 when compared to non-convertors. The strengths of the associations varied between cohorts and between markers but similar trends were observed between the four cohorts and the two markers. Discussion There is a strongly increased risk of progressing to disease among DAT and/or rK39 seropositives with high titers. The options for prophylactic treatment for this group merit further investigation, as it could be of clinical benefit if it prevents progression to disease. Prophylactic treatment might also have a public health benefit if it can be corroborated that these asymptomatically infected individuals are infectious for sand flies.

Active case detection in national visceral leishmaniasis elimination programs in Bangladesh, India, and Nepal: feasibility, performance and costs

BackgroundActive case detection (ACD) significantly contributes to early detection and treatment of visceral leishmaniasis (VL) and post kala-azar dermal leishmaniasis (PKDL) cases and is cost effective. This paper evaluates the performance and feasibility of adapting ACD strategies into national programs for VL elimination in Bangladesh, India and Nepal.MethodsThe camp search and index case search strategies were piloted in 2010-11 by national programs in high and moderate endemic districts / sub-districts respectively. Researchers independently assessed the performance and feasibility of these strategies through direct observation of activities and review of records. Program costs were estimated using an ingredients costing method.ResultsAltogether 48 camps (Bangladesh-27, India-19, Nepal-2) and 81 index case searches (India-36, Nepal-45) were conducted by the health services across 50 health center areas (Bangladesh-4 Upazillas, India-9 PHCs, Nepal-37 VDCs). The mean number of new case detected per camp was 1.3 and it varied from 0.32 in India to 2.0 in Bangladesh. The cost (excluding training costs) of detecting one new VL case per camp varied from USD 22 in Bangladesh, USD 199 in Nepal to USD 320 in India. The camp search strategy detected a substantive number of new PKDL cases. The major challenges faced by the programs were inadequate preparation, time and resources spent on promoting camp awareness through IEC activities in the community. Incorrectly diagnosed splenic enlargement at camps probably due to poor clinical examination skills resulted in a high proportion of patients being subjected to rK39 testing.ConclusionNational programs can adapt ACD strategies for detection of new VL/PKDL cases. However adequate time and resources are required for training, planning and strengthening referral services to overcome challenges faced by the programs in conducting ACD.

Visceral Leishmaniasis Clinical Management in Endemic Districts of India, Nepal, and Bangladesh

Background. National VL Elimination Programs in India, Nepal and Bangladesh face challenges as home-based Miltefosine treatment is introduced. Objectives. To study constraints of VL management in endemic districts within context of national elimination programs before and after intervention. Methods. Ninety-two and 41 newly diagnosed VL patients were interviewed for clinical and provider experience in 2009 before and in 2010 after intervention (district training and improved supply of diagnostics and drugs). Providers were assessed for adherence to treatment guidelines. Facilities and doctor-patient consultations were observed to assess quality of care. Results. Miltefosine use increased from 33% to 59% except in Nepal where amphotericin was better available. Incorrect dosage and treatment interruptions were rare. Advice on potential side effects was uncommon but improved significantly in 2010. Physicians did not rule out pregnancy prior to starting Miltefosine. Fever measurement or spleen palpation was infrequently done in Bangladesh but improved after intervention (from 23% to 47%). Physician awareness of renal or liver toxicity as Miltefosine side effects was lower in Bangladesh. Bio-chemical monitoring was uncommon. Patient satisfaction with services remained low for ease of access or time provider spent with patient. Health facilities were better stocked with rK39 kits and Miltefosine in 2010.

Health & Demographic Surveillance System Profile: The Muzaffarpur-TMRC Health and Demographic Surveillance System

The Muzaffarpur-TMRC Health and Demographic Surveillance System (HDSS), established in 2007, was developed as an enlargement of the scope of a research collaboration on the project Visceral Leishmaniasis in Bihar, which had been ongoing since 2005. The HDSS is located in a visceral leishmaniasis (VL)-endemic area in the Muzaffarpur district of Bihar state in India. It is the only HDSS conducting research on VL, which is a vector-borne infectious disease transmitted by female phlebotomine sandflies and is fatal if left untreated. Currently the HDSS serves a population of over 105,000 in 66 villages. The HDSS collects data on vital events including pregnancies, births, deaths, migration and marriages, as well as other socio-economic indicators, at regular intervals. Incident VL cases are identified. The HDSS team is experienced in conducting both qualitative and quantitative studies, sample collection and rapid diagnostic tests in the field. In each village, volunteers connect the HDSS team with the community members. The Muzaffarpur-TMRC HDSS provides opportunities for studies on VL and other neglected tropical diseases (NTDs) and their interaction with demographic events such as migration.

Factors affecting default among pre-ART patients in Eastern Uttar Pradesh

Methods This cross sectional study was conducted at ART centre, COE, BHU. All patients 18 years of age and above defaulted from pre-ART HIV care were included in the study. Defaulters were defined as any patients who missed their last appointment of CD4 count by more than one month (missed) & more than three months (lost to follow up). All these patients were traced telephonically and interviewed after taking consent. Statistical analysis was done by using SPSS version 15.0.

Menstrual hygiene practices in context of schooling: A community study among rural adolescent girls in Varanasi

Introduction: Up until now, poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. The lack of attention to this issue is striking as we cannot achieve several Millennium Development Goals (MDGs), that is, 2, 3 4,5, and5B. This study aimed to assess the level of awareness about menarche and hygienic practices during menstruation in context of schooling . Materials and Methods: Community-based cross-sectional study using a mix method approach (qualitative and quantitative). It was conducted among 650 adolescent girls in the field practice area of Rural Health and Training Centre, Chiraigaon block of district Varanasi between January and June2011. Pretested, semistructured interview schedule was used. Data were analyzed statistically by using Statistical Package for Social Sciences (SPSS) software. Results: Out of the total 650 respondents, 590 (90.78%) had attained menarche at the time of interview and only one-third of the respondents (29.4%) were aware of menstruation before menarche and sisters (55%) played the key role in providing information to them. Only 31% respondents were using sanitary pads during menstruation. Self-reported reproductive tract infection (RTI) was observed more in respondents not maintaining hygienic practices (6.6%) as compared to those maintaining hygiene (2.6%). Conclusion and Recommendations: From the Focus Group Discussions (FGDs) as well as quantitative survey it was observed that the awareness about menarche before its onset was still poor in rural areas. Significant association (P < 0.05) was observed between respondent education and their awareness about menarche before its onset. Therefore, it is recommended that teachers can play an influential role in informing them about changes during adolescence, especially about menarche and other issues related to menstruation. As per the present study, sisters and mothers were the major source of information. Therefore, there is a need for the provision of comprehensive family life education for the parents also.

Why do Patients in Pre-Anti Retroviral Therapy (ART) Care Default: A Cross-Sectional Study.

Background and Objectives: Approximately, 40% of the patients registered in the National AIDS Control Program in India are not on antiretroviral therapy (ART), i.e., are in pre-ART care. However, there are scarce data regarding the retention of pre-ART patients under routine program conditions. The main objective of this study was to find out the reasons for default among patients in pre-ART care. Materials and Methods: Patients enrolled in the ART Centre, Banaras Hindu University (BHU) between January and December 2009 and in pre-ART care were included in the study. Defaulters were those pre-ART patients who missed their last appointment of CD4 count by more than 1 month. Defaulters were traced telephonically in 2011 and those who returned and gave their consent for the study were interviewed using a semi-structured questionnaire. Results: Out of 620 patients in pre-ART care, 384 (68.2%) were defaulters. One hundred forty-four of the defaulters were traced and only 83 reached the ART center for interview. Among defaulters who did not reach the ART center, illiterate and unmarried were significantly more and mean duration from registration to default was also significantly less as compared to those who came back for the interview. Most defaulters gave more than one reason for defaulting that were as follows: Inconvenient clinic timings (98%), need for multiple mode of transport (92%), perceived improved health (65%), distance of center from home (61%), lack of social support (62%), and financial difficulty (59%). Interpretation and Conclusion: Active tracing of pre-ART patients through outreach and strengthening of the Link ART centers will improve the retention of patients in the program.

Visceral Leishmaniasis in the Muzaffapur Demographic Surveillance Site: A Spatiotemporal Analysis

Abstract. In the Indian subcontinent, visceral leishmaniasis (VL) has a strongly clustered distribution. The “index case approach” is promoted both for active case finding and indoor residual spraying (IRS). Uncertainty exists about the optimal radius. Buffer zones of 50–75 m around incident cases have been suggested for active case finding, for IRS the recommendation is to cover a radius of 500 m. Our aim was to establish optimal target areas both for IRS and for (re)active case finding. We plotted incident VL cases on a map per 6-month period (January–June or July–December) and drew buffers of 0 (same household), 50, 75, 100, 200, 300, 400, and 500 m around these cases. We then recorded total population and numbers of VL cases diagnosed over the next 6-month period in each of these buffers and beyond. We calculated incidence rate ratios (IRRs) using the population at more than 500 m from any case as reference category. There was a very strong degree of spatial clustering of VL with IRRs ranging from 45.2 (23.8–85.6) for those living in the same households to 14.6 (10.1–21.2) for those living within 75 m of a case diagnosed, during the previous period. Up to 500 m the IRR was still five times higher than that of the reference category. Our findings corroborate the rationale of screening not just household contacts but also those living within a perimeter of 50–75 m from an index case. For IRS, covering a perimeter of 500 m, appears to be a rational choice.

Awareness of legal and social issues related to reproductive health among adolescent girls in rural Varanasi

Background: Data on awareness of adolescents on the legal and social issues/acts related to reproductive health, especially in rural areas, are scarce. Objectives: The aim of the present cross-sectional study is to assess the awareness level of legal and social issues related to reproductive health and its association with the various individual and family/household level characteristics. Methods: 650 adolescent girls in the age group of 15–19 years were interviewed with the help of pretested and semistructured questionnaire and focus group discussions were also conducted for qualitative findings in Chiraigaon block of district Varanasi. Results: It was observed that 42.9% of the respondents were aware of legal age of marriage, 14.9% knew about the right age of childbearing. Dowry prohibition act and domestic violence act were known to 46% and 27% respondents, respectively, and only 2.6% were aware of medical termination of pregnancy act. Logistic regression analysis shows the significant effect of education on awareness of legal age of marriage, right age of childbearing, domestic violence, and dowry prohibition acts, which is also supported by qualitative findings. Conclusion: All the important legal issues/acts should be included in high school curriculum and female teachers should be involved in training program for adolescents. Role of mass media in creating awareness about these issues in their routine programs should be ascertained. Accredited Social Health Activist and Anganwadi workers should be aware of and include these issues/acts in adolescent meetings.
