Evaluation of key survey components of bio-behavioral surveillance among HIV high-risk subpopulation in Western India.

BACKGROUND: High-quality data are of prime importance in any health survey because survey data are considered as a gold standard for nationally representative data. The quality of data collection largely depends on the design of the questionnaire, training, and skills of the interviewer. OBJECTIVES: In the present study, we tried to evaluate three key components, such as questionnaire design, human resource and training of the field staff for Integrated Biological and Behavioural Surveillance carried out among the HIV high-risk subpopulation. METHODS: A mixed-methods approach was used. Qualitative and quantitative data collection was carried out in the year 2015 with cross-sectional survey design in western states of India. The in-depth interviews of 10 stakeholders, structured interviews of the survey respondents (n = 560), and field investigators (n = 71) were conducted. Data triangulation was used to find out the concurrence of the qualitative and quantitative data. RESULTS: Comprehensive and standardized survey questionnaire, structured training agenda, and strategic preparation for recruiting human resources were the overall strengths of the survey. However, during the implementation of the survey, there were some difficulties reported in data collection process. Overall, the respondents and investigators felt that the questionnaire was long and exhaustive. Difficulties were faced while collecting data on sexual history. The field staffs were not adequately experienced to work with sensitive population. CONCLUSIONS: In order to have accurate, reliable data, especially on sexual behavior; emphasis should be given on simple questionnaire with the use of community-friendly language, skilled and experienced interviewers for data collection, and extensive field training.

Use of Computer-Assisted Personal Interviewing and Information Management System in a Survey among HIV High-Risk Groups in India: Strengths, Weaknesses, Opportunities, and Threats Analysis.

OBJECTIVES: In India, integrated biological and behavioral surveillance was carried out in 2014-2015 among high-risk key population as a part of second-generation HIV surveillance system. Computer-assisted personal interviewing and integrated information management system were used for the first time in this large national field based survey. We evaluated the strengths and weaknesses of technology use in this survey. METHODS: Mixed methods comprising of the key informant's interviews and structured data collected from field interviewers were used to do the strengths, weaknesses, opportunities, and threats analysis with defined attributes. RESULTS: Despite the challenges, the technology use in this survey was a huge success with respect to data coverage, response rates, real-time data, and acceptance by respondents. However, such techniques require more focus on the competency of human resource, training, and concurrent evaluation systems to get better data quality, time adherence, and effective use of technology. CONCLUSION: The recommendations resulted from this analysis will help for strategic management while designing such systems in field-based community surveys.

Differing HIV vulnerability among female sex workers in a high HIV burden Indian state.

INTRODUCTION: The HIV sentinel surveillance [HSS] conducted in 2010-11 among female sex workers [FSW] in the state of Maharashtra, India provided an opportunity to assess characteristics of different types of FSWs and their HIV risk. It is important for India's National AIDS Control Program, to understand the differences in vulnerability among these FSW, in order to define more specific and effective risk reduction intervention strategies. Therefore, we analyzed data from HSS with the objective of understanding the HIV vulnerability among different types of FSW in Maharashtra. MATERIAL AND METHODS: Cross sectional data collected as a part of HSS among FSWs in year 2010-11 from 21 sentinel sites in the state of Maharashtra were analyzed to understand the vulnerability and characteristics of different types of female sex workers based on their place of solicitation using multinomial logistic regression. RESULTS: While the HIV prevalence was 6.6% among all FSWs, it was 9.9% among brothel based [BB], 9% among street based [SB] and 3.1% and 3.7% among home based [HB], and bar based [Bar-B] sex workers respectively. SB FSWs were least likely to be located in HIV low burden districts [ANC] [ARRR: 0.61[95% CI: 0.49, 0.77]], but were 6 times more likely to be recently [<1 year] involved in sex work [ARRR: 6.15 [95% CI: 3.15, 12.0]]. The number of clients of SB FSWs in the preceding week were lower than 11% [ARRR: 0.89 [95%CI: 0.87, 0.90]] as compared to the BB FSWs denoting lesser client load. The duration since last paid sex was shorter [ARRR: 0.94[95%CI: 0.91, 0.96]] as compared to the BB FSWs. CONCLUSION: Street based FSWs have emerged as one of the most vulnerable types of FSW with a high HIV prevalence similar to BB FSWs. Our study reveals that they have more frequent sex acts despite lower client loads, and are more likely to be located in districts highly affected by HIV (ANC prevalence >1%). We identify them as a group to be focused on for prevention interventions and it is likely that they would be easily amenable to novel interventions due to their higher literacy rate as compared to other typologies.

Antibiotic susceptibility pattern of Neisseria gonorrhoeae strains isolated from five cities in India during 2013-2016.

PURPOSE: Emergence of multidrug resistance in Neisseria gonorrhoeae, an STI of public health significance is the biggest challenge to gonorrhoea control. Monitoring for antimicrobial resistance is essential for the early detection of emergent drug resistance patterns. METHODOLOGY: One hundred and twenty four N. gonorrhoeae strains were isolated between September 2013-August 2016 [82-New Delhi, 3-Pune, 3-Mumbai, 20-Secunderabad and 16-Hyderabad] to determine antimicrobial susceptibility and to compare the CLSI disc diffusion method with Etest for these strains. The results of the two methods were compared by using kappa statistics. RESULTS: Ninety eight percent [CI: 96.2-100] of isolates were resistant to ciprofloxacin, 52 % [CI: 43.2-60.8] to penicillin, 56 % [CI: 47.2-64.7] to tetracycline and 5 % [CI: 1.2-8.8] to azithromycin. All the strains were susceptible to spectinomycin, ceftriaxone and cefixime except for two strains which showed decreased susceptibility to ceftriaxone and cefixime. Kappa scores for penicillin, azithromycin, ciprofloxacin, ceftriaxone and cefixime showed that the CLSI method had high agreement with Etest while tetracycline had substantial agreement. CONCLUSION: Our data suggest that the disc diffusion method which is both cost effective and more feasible, can effectively be used routinely for monitoring antibiotic susceptibility in N. gonorrhoeae, in limited resource countries like India. We demonstrate the emergence of decreased susceptibility to ceftriaxone and cefixime and threshold levels of resistance to azithromycin in India. This underscores the importance of maintaining continued surveillance for antibiotic resistance in N. gonorrhoeae and a potential requirement for strategic change in guidelines in the not so distant future.

Detection of Cytomegalovirus in Bronchoalveolar Lavage Fluid from HIV-Positive Individuals with Community Acquired Pneumonia.

INTRODUCTION: Cytomegalovirus (CMV) pneumonia is one of the frequent viral pneumonia reported in persons with HIV infection. Knowledge of pulmonary CMV infection is important for deciding appropriate diagnostic strategies. However, there is scanty literature addressing the role of CMV aetiology among HIV positive individuals presenting with Community Acquired Pneumonia (CAP) using Bronchoalveolar Lavage (BAL) samples from India. AIM: To detect CMV in BAL fluid from HIV-positive individuals presenting with CAP. MATERIALS AND METHODS: This cross-sectional study was conducted using 107 archival BAL samples collected from consecutive HIV-positive patients presenting with CAP as per the Indian Chest Society and National College of Chest Physicians guidelines at the Department of Chest and Tuberculosis, Sassoon General Hospitals, Pune, India. The samples were tested for CMV by Polymerase Chain Reaction (PCR) targeting the IRL11 region at the National AIDS Research Institute, Pune. RESULTS: Of the 107 BAL samples tested, 8 (7.4 %) were positive for CMV, while CMV was the sole pathogen in 5 (4.7%) cases. Co-infection with other pathogens was seen in 3 patients and Mycobacterium tuberculosis, Pneumocystis jiroveci and Streptococcus pneumoniae were the co-pathogens. Five patients had fatal clinical outcome of which three had CMV as the sole pathogen. CONCLUSION: Ours is the first study to detect Cytomegalovirus (CMV) in bronchoalveolar lavage samples from HIV-positive individuals presenting with community acquired pneumonia from India and indicates the need for further multicentre studies to understand pulmonary CMV infection, which will eventually help in designing appropriate diagnostic strategies and therapeutic interventions.

Rates and determinants of incidence and clearance of cervical HPV genotypes among HIV-seropositive women in Pune, India.

BACKGROUND: Several studies in recent years have documented the genotype-specific prevalence of HPV infection and wide diversity and multiplicity of HPV genotypes among HIV-seropositive women. Yet, information on changes in HPV genotype-specific incidence and clearance rates over time, and their correlation with clinical or immunologic factors among HIV-seropositive women is scarce. OBJECTIVES: We conducted a prospective study to investigate the incidence and clearance rates of cervical HPV genotypes among HIV-seropositive women in India and expand the evidence base in this area of research. STUDY DESIGN: Cervical samples were collected from n=215 HIV-seropositive women in Pune, India who underwent two screening visits separated by a median of 11-months (interquartile range: 8-18 months). HPV genotypes were determined by Roche Linear Array HPV assay. Individual genotype-specific and carcinogenicity-grouping-specific HPV incidence and clearance rates were calculated and the associations between incidence/clearance and age and HIV-related metrics were explored. RESULTS: Incidence and clearance rates for 'any HPV' and 'carcinogenic HPV' genotypes were 11.1 and 18.3, and 6.7 and 33.8, per 100 person-years, respectively. Incidence and clearance rates for HPV genotypes of alpha-9 species (HPV16, HPV31, HPV33, HPV35, HPV52 and HPV58) and alpha-7 species (HPV18, HPV39, HPV45, HPV59 and HPV68) were 5.8 and 2.04, and 32.1 and 53.5, per 100 person-years, respectively. Clearance of any HPV type was associated with increasing age of participants (odds ratio: 1.08, 95%CI: 1.004-1.17), although the association marginally lost its statistical significance when adjusted for CD4 counts and antiretroviral therapy status. CONCLUSIONS: Genotype-specific clearance rates of HPV were higher than corresponding incidence rates. The suggestion of a positive associations of increasing age with HPV clearance points to the need for etiologic studies on age-related hormonal changes on clearance of cervical HPV infection.

HIV and cancer registry linkage identifies a substantial burden of cancers in persons with HIV in India.

We utilized computerized record-linkage methods to link HIV and cancer databases with limited unique identifiers in Pune, India, to determine feasibility of linkage and obtain preliminary estimates of cancer risk in persons living with HIV (PLHIV) as compared with the general population.Records of 32,575 PLHIV were linked to 31,754 Pune Cancer Registry records (1996-2008) using a probabilistic-matching algorithm. Cancer risk was estimated by calculating standardized incidence ratios (SIRs) in the early (4-27 months after HIV registration), late (28-60 months), and overall (4-60 months) incidence periods. Cancers diagnosed prior to or within 3 months of HIV registration were considered prevalent.Of 613 linked cancers to PLHIV, 188 were prevalent, 106 early incident, and 319 late incident. Incident cancers comprised 11.5% AIDS-defining cancers (ADCs), including cervical cancer and non-Hodgkin lymphoma (NHL), but not Kaposi sarcoma (KS), and 88.5% non-AIDS-defining cancers (NADCs). Risk for any incident cancer diagnosis in early, late, and combined periods was significantly elevated among PLHIV (SIRs: 5.6 [95% CI 4.6-6.8], 17.7 [95% CI 15.8-19.8], and 11.5 [95% CI 10-12.6], respectively). Cervical cancer risk was elevated in both incidence periods (SIRs: 9.6 [95% CI 4.8-17.2] and 22.6 [95% CI 14.3-33.9], respectively), while NHL risk was elevated only in the late incidence period (SIR: 18.0 [95% CI 9.8-30.20]). Risks for NADCs were dramatically elevated (SIR > 100) for eye-orbit, substantially (SIR > 20) for all-mouth, esophagus, breast, unspecified-leukemia, colon-rectum-anus, and other/unspecified cancers; moderately elevated (SIR > 10) for salivary gland, penis, nasopharynx, and brain-nervous system, and mildly elevated (SIR > 5) for stomach. Risks for 6 NADCs (small intestine, testis, lymphocytic leukemia, prostate, ovary, and melanoma) were not elevated and 5 cancers, including multiple myeloma not seen.Our study demonstrates the feasibility of using probabilistic record-linkage to study cancer/other comorbidities among PLHIV in India and provides preliminary population-based estimates of cancer risks in PLHIV in India. Our results, suggesting a potentially substantial burden and slightly different spectrum of cancers among PLHIV in India, support efforts to conduct multicenter linkage studies to obtain precise estimates and to monitor cancer risk in PLHIV in India.

Short Communication: Limited HIV Pretreatment Drug Resistance Among Adults Attending Free Antiretroviral Therapy Clinic of Pune, India.

In India, the roll out of the free antiretroviral therapy (ART) program completed a decade of its initiation in 2014. The success of first-line ART is influenced by prevalence of HIV pretreatment drug resistance (PDR) in the population. In this cross-sectional study, we sought to determine the prevalence of PDR among adults attending the state-sponsored free ART clinic in Pune in western India. Fifty-two individuals eligible for ART as per national guidelines with median CD4 cell count of 253 cells/mm(3) (inter quartile range: 149-326) were recruited between January 2014 and April 2015. Population-based sequencing of partial pol gene sequences from plasma specimen revealed predominant HIV-1 subtype C infection (96.15%) and presence of single-drug resistance mutations against non-nucleoside reverse transcriptase inhibitor in two sequences. The study supports the need for periodic surveillance, when offering PDR testing at individual level is not feasible.

Molecular mechanisms associated with Fluconazole resistance in clinical Candida albicans isolates from India.

Resistance to azole antifungals is a significant problem in Candida albicans. An understanding of resistance at molecular level is essential for the development of strategies to tackle resistance and rationale design of newer antifungals and target-based molecular approaches. This study presents the first evaluation of molecular mechanisms associated with fluconazole resistance in clinical C.albicans isolates from India. Target site (ERG11) alterations were determined by DNA sequencing, whereas real-time PCRs were performed to quantify target and efflux pump genes (CDR1, CDR2, MDR1) in 87 [Fluconazole susceptible (n = 30), susceptible-dose dependent (n = 30) and resistant (n = 27)] C.albicans isolates. Cross-resistance to fluconazole, ketoconazole and itraconazole was observed in 74.1% isolates. Six amino acid substitutions were identified, including 4 (E116D, F145L, E226D, I437V) previously reported ones and 2 (P406L, Q474H) new ones. CDR1 over-expression was seen in 77.7% resistant isolates. CDR2 was exclusively expressed with CDR1 and their concomitant over-expression was associated with azole cross-resistance. MDR1 and ERG11 over-expression did not seem to be associated with resistance. Our results show that drug efflux mediated by Adenosine-5'-triphosphate (ATP)-binding cassette transporters, especially CDR1 is the predominant mechanism of fluconazole resistance and azole cross-resistance in C. albicans and indicate the need for research directed towards developing strategies to tackle efflux mediated resistance to salvage azoles.

Differing Identities but Comparably High HIV and Bacterial Sexually Transmitted Disease Burdens Among Married and Unmarried Men Who Have Sex With Men in Mumbai, India.

BACKGROUND: Although HIV incidence has declined in India, men and transgender women who have sex with men (MSM) continue to have high rates of HIV and sexually transmitted disease (STD). Indian MSM face substantial pressures to marry and have families, but the HIV/STD burden among married Indian MSM is not well characterized. METHODS: A diverse sample of Indian MSM were recruited through respondent-driven sampling. Independent variables that produced a P value of 0.10 or less were then added to a multivariable logistic regression model. RESULTS: Most of the 307 MSM (95 married and 212 unmarried) recruited into the study were younger than 30 years, and less than one-third had more than a high school education. Almost two-thirds of the married men had children, compared with 1.4% of the unmarried men (P < 0.001). The numbers of condomless anal sex acts did not differ by marriage status. Although unmarried MSM more often identified themselves as "kothi" (receptive role), their rates of HIV or bacterial STD were similar to married MSM, with 14.3% being HIV infected. The respondent-driven sampling-adjusted prevalence of any bacterial STD was 18.3% for married MSM and 20% for unmarried MSM (not significant). Participants reported high levels of psychological distress, with 27.4% of married and 20.1% of unmarried MSM reporting depressive symptoms (not significant). CONCLUSIONS: Men who have sex with men in Mumbai had high rates of HIV, STD, and behavioral health concerns. Clinicians need to become more comfortable in eliciting sexual histories so that they can identify MSM who need HIV/STD treatment and/or prevention services.

Education, gender, and state-level disparities in the health of older Indians: Evidence from biomarker data.

Using new biomarker data from the 2010 pilot round of the Longitudinal Aging Study in India (LASI), we investigate education, gender, and state-level disparities in health. We find that hemoglobin level, a marker for anemia, is lower for respondents with no schooling (0.7g/dL less in the adjusted model) compared to those with some formal education and is also lower for females than for males (2.0g/dL less in the adjusted model). In addition, we find that about one third of respondents in our sample aged 45 or older have high C-reaction protein (CRP) levels (>3mg/L), an indicator of inflammation and a risk factor for cardiovascular disease. We find no evidence of educational or gender differences in CRP, but there are significant state-level disparities, with Kerala residents exhibiting the lowest CRP levels (a mean of 1.96mg/L compared to 3.28mg/L in Rajasthan, the state with the highest CRP). We use the Blinder-Oaxaca decomposition approach to explain group-level differences, and find that state-level disparities in CRP are mainly due to heterogeneity in the association of the observed characteristics of respondents with CRP, rather than differences in the distribution of endowments across the sampled state populations.

External quality control for dried blood spot-based C-reactive protein assay: experience from the indonesia family life survey and the longitudinal aging study in India.

Measurement of C-reactive protein (CRP), a marker of inflammation, in dried blood spots has been increasingly incorporated into community-based social surveys internationally. Although the dried blood spot-based CRP assay protocol has been validated in the United States, it remains unclear whether laboratories in other less-developed countries can generate CRP results of similar quality. We therefore conducted external quality monitoring for dried blood spot-based CRP measurement for the Indonesia Family Life Survey and the Longitudinal Aging Study in India. Our results show that dried blood spot-based CRP results in these two countries have excellent and consistent correlations with serum-based values and dried blood spot-based results from the reference laboratory in the United States. Even though the results from duplicate samples may have fluctuations in absolute values over time, the relative order of C-reactive protein levels remains similar, and the estimates are reasonably precise for population-based studies that investigate the association between socioeconomic factors and health.

The effects of antiretroviral treatment initiation on cognition in HIV-infected individuals with advanced disease in Pune, India.

There has been a reduction in the most severe cases of HIV-associated neurocognitive disorders (HAND) with advances in antiretroviral treatment (ART). But the prevalence of milder forms of HAND still remains high. Data from systematically conducted studies on the effects of ART on cognition are scanty in India, where HIV-1 clade C is prevalent. The purpose of the present study was to assess the effect of antiretroviral therapy in HIV-seropositive (HIV+) individuals (n = 92) with CD4 cell counts <200 cells/mm(3). The overall and domain-specific levels of cognitive functioning were determined using a locally recruited normative sample, and a change in neurocognitive functioning at the 1-year follow-up visit was analyzed. Results revealed cognitive impairment in 44.6 % of the HIV+ group at baseline. At the 1-year follow-up, the group showed significant improvement in the Learning domain (p < 0.05). HIV+ individuals showing improvement in the global cognitive scores had a significantly lower baseline CD4 cell count compared to others. Overall, the degree of improvement associated with the magnitude of rise in CD4 suggests the possibility that early, mild subclinical deficits may also benefit from treatment.

Pseudomembranous Type of Oral Candidiasis is Associated with Decreased Salivary Flow Rate and Secretory Immunoglobulin A Levels.

Saliva plays an important role in maintaining microbial homeostasis in the oral cavity, while salivary gland hypofunction predisposes the oral mucosa to pathologic alteration and increases the risk for oral candidiasis. This study sought to determine the salivary flow rate (SFR) and secretory immunoglobulin A (SIgA) levels in HIV-positive and HIV-negative individuals and evaluate their relationship with the determinants of oral candidiasis. Sixty HIV-positive (30 with and 30 without oral candidiasis) and 30 healthy HIV-negative individuals were enrolled. Cotton pellet was weighed pre- and post-saliva collection for the assessment of SFR, while SIgA levels were estimated by commercial ELISA (Diametra, Italy) kit. The mean ± SD, SFR and SIgA levels in HIV-positive individuals with candidiasis, without candidiasis and HIV-negative controls were 0.396 ± 0.290, 0.546 ± 0.355 and 0.534 ± 0.214 ml/min and 115.891 ± 37.621, 136.024 ± 51.075 and 149.418 ± 31.765 µg/ml, respectively. A positive correlation between low CD4 counts (indicator of immunodeficiency) and SIgA was observed in HIV-positive individuals with candidiasis (r = 0.373, p = 0.045). We also report here for the first time the significant decrease in SFR and SIgA levels in individuals presenting with pseudomembranous type of oral candidiasis and Candida albicans infection.

Validation and modification of dried blood spot-based glycosylated hemoglobin assay for the longitudinal aging study in India.

OBJECTIVES: This study aims to validate a modified dried blood spot (DBS)-based glycosylated hemoglobin (HbA1c) assay protocol, after a pretest in India showed poor correlation between the original DBS-based protocol and venous results. METHODS: The original protocol was tested on different chemistry analyzers and then simplified at the University of Washington (UW). A second pretest was conducted in India to validate the modified assay protocol, using 44 quality control specimens. RESULTS: Data from UW indicated that, using the original protocol, the correlation coefficients between DBS and venous results were above 0.98 on both Bio-Rad and Olympus chemistry analyzers. The protocol worked equally well on filter paper, with or without pre-treatment, and when the recommended amount of blood spot material, or less, was used. A second pretest of the modified protocol confirmed that DBS-based levels from both Olympus and Roche chemistry analyzers were well correlated with DBS results from UW (correlation coefficients were above 0.96), as well as with venous values (correlation coefficients were above 0.94). CONCLUSIONS: The DBS-based HbA1c values are highly correlated with venous results. The pre-treatment of filter paper does not appear to be necessary. The poor results from the first pretest are probably due to factors unrelated to the protocol, such as problems with the chemistry analyzer or assay reagents.

Antimicrobial activity of plant extracts against sexually transmitted pathogens.

Comprehensive management of sexually transmitted infections (STIs) using vaginal or rectal microbicide-based intervention is one of the strategies for prevention of HIV infection. Herbal products have been used for treating STIs traditionally. Herein, we present in vitro activity of 10 plant extracts and their 34 fractions against three sexually transmitted/reproductive tract pathogens - Neisseria gonorrhoeae, Haemophilus ducreyi and Candida albicans. The plant parts were selected; the extracts/fractions were prepared and screened by disc diffusion method. The minimum inhibitory and minimum cidal concentrations were determined. The qualitative phytochemical analysis of selected extracts/fractions showing activity was performed. Of the extracts/fractions tested, three inhibited C. albicans, ten inhibited N. gonorrhoeae and five inhibited H. ducreyi growth. Our study demonstrated that Terminalia paniculata Roth. extracts/fractions inhibited growth of all three organisms. The ethyl acetate fraction of Syzygium cumini Linn. and Bridelia retusa (L.) Spreng. extracts was found to inhibit N. gonorrhoeae at lowest concentrations.

Pneumocystis jirovecii infection and the associated dihydropteroate synthase (DHPS) and dihydrofolate reductase (DHFR) mutations in HIV-positive individuals from Pune, India.

The present study was undertaken to detect Pneumocystis jirovecii infection among HIV-positive patients presenting with symptoms of lower respiratory tract infection and analyze the associated dihydropteroate synthase (DHPS) and dihydrofolate reductase (DHFR) mutations. P. jirovecii infection was detected in 12.6% cases. We did not find DHPS gene mutations at the commonest positions of codon 55 and 57; however, mutation at codon 171 was detected in two cases. No mutations in DHFR gene were detected. The results indicate low prevalence of DHPS and DHFR mutations in Indian P. jirovecii isolates, suggesting that the selective pressure of sulfa drugs on the local strains has probably not reached the levels found in developed nations.

Clinical profile of HIV infected patients attending a HIV referral clinic in Pune, India.

BACKGROUND & OBJECTIVES: Human immunodeficiency virus (HIV) has infected several million individuals in India. Various interventions have been implemented for early detection and prevention of transmission of HIV infection. This has progressively changed the clinical profile of HIV infected individuals and this study documents the clinical presentation of individuals positive for HIV in 2010, in Pune, Maharashtra, India. METHODS: This cross-sectional study included subjects who had come to the HIV referral clinic for HIV testing from January to December 2010. Children as well as individuals with indeterminate HIV result were excluded from the study, and data for 1546 subjects were finally analysed. RESULTS: The HIV positivity rate among all referred cases for the year 2010 was 35 per cent (male 55% and females 45%). The median age (Q1, Q3) was 31 (25.75, 39) yr. The median CD4 cell count for all HIV infected individuals (whose CD4 count was available n=345) was 241 cells/µl and for asymptomatic HIV infected individuals was 319 cells/µl. There were 673 (43.5%) symptomatic and 873 (56.5%) asymptomatic participants. Fever, breathlessness, cough with expectoration, weight loss, loss of appetite, generalized weakness, pallor and lymphadenopathy (axillary and cervical) were found to be associated (P<0.001) with HIV positivity. On multivariate analysis, history of Herpes zoster [AOR 11.314 (6.111-20.949)] and TB [AOR 11.214 (6.111-20.949)] was associated with HIV positivity. INTERPRETATION & CONCLUSIONS: Signs and symptoms associated with HIV positivity observed in this study can be used by health care providers to detect HIV infection early. Moreover, similar to HIV testing in patients with tuberculosis, strategies can be developed for considering Herpes zoster as a predictor of HIV infection.
