Prevalence, risk factors and morbidities of gestational diabetes among pregnant women attending a hospital in an urban area of Bhubaneswar, Odisha.

BACKGROUND: Gestational diabetes mellitus (GDM) causes several maternal and neonatal complications. AIMS: This exploratory study was conducted to estimate the prevalence, determine the risk factors and morbidities among pregnant women. METHODS: In this prospective study, 1557 pregnant women attending the Gyn. & Obs. clinic of a hospital in an urban area of Bhubaneswar were enrolled. Various socio-demographic factors and clinical profiles were assessed. We used a Glucometer for the diagnosis of GDM. RESULTS: More younger pregnant women residing in slums, sedentary and overweight were having diabetes. A large percentage of pregnant women living in rural areas and slums visit the government hospitals as they are benefitted by the State govt.'s scheme, Mamata. Pregnant women residing in the urban areas prefer to go for ante-natal check-ups in private Nursing homes/Clinics owing to the crowd and prolonged waiting hours. In this study, body mass index (BMI) and family history of the pregnant women appeared to be the significant risk factors for the gestational diabetes. Out of 1557 pregnant women, 154 were having diabetes, the prevalence being 9.89%. This is low when compared to the studies reported from other regions of the country. CONCLUSIONS: Gluco-One is suitable for screening gestational diabetes using the optimal threshold capillary glucose level of 140 mg/dl. As the pregnant women find it difficult to come the next day just to collect the results, this facilitated in getting the test results promptly and appropriate consultation by Doctor the same day. Glucometer can be used for accurate screening of gestational diabetes mellitus. Pregnant women with screening values not normal were identified on the spot and followed up at regular intervals. Screening for diabetes among pregnant women would result in early case detection indirectly resulting in better outcomes of treatment and prevention of complications.

Human immunodeficiency virus and hepatitis B virus co-infections among tuberculosis patients attending a Model Rural Health Research Unit in Ghatampur, North India.

INTRODUCTION: This prospective cross-sectional hospital-based study was carried out in order to assess the prevalence of human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infections among patients with active tuberculosis (TB) disease attending an Outpatient Department (OPD) at the Model Rural Health Research Unit in Ghatampur, a rural village in Kanpur district. MATERIALS AND METHODS: The socio-demographic features and clinical profile of the TB patients were analysed in the context of symptoms at the time of testing. The HIV and HBV status were determined and correlated with clinical features at the time of testing. RESULTS: In our study, the prevalence of HIV infection among TB patients is 1.48% (18/1215) and that of HBsAg reactivity was found to be 2.96% (36/1215). During 2007-2010, the HIV-positivity varied between 1.5% and 1.45% whereas HBV reactivity ranged between 2.4% and 3.63%.A substantial percentage of the TB patients attending the OPD in Ghatampur harbour HIV and HBV infections, which otherwise would remain undiagnosed without serological screening. CONCLUSION: Co infection with HBV among TB patients potentiate the risk of anti-tuberculous therapy-induced hepatotoxicity, therefore, exercising caution and carefully monitoring the patients for drugs associated hepatotoxicity is essential. There is an urgent need to perform population-based surveys of HIV and hepatitis infections among TB patients to assess the true extent of the problem. Efforts should be made to make physicians aware of the peculiarities and manage these patients effectively.

CD4+, CD8+, CD3+ cell counts and CD4+/CD8+ ratio among patients with mycobacterial diseases (leprosy, tuberculosis), HIV infections, and normal healthy adults: a comparative analysis of studies in different regions of India.

In this study, we estimated the CD4+, CD8+, CD3+ cell counts and the CD4/CD8 ratio among normal healthy controls (adults and children), leprosy patients (without any complications and during reactional states), TB patients (with and without HIV), and HIV-positive patients (early infection and full-blown AIDS) and correlated the changes with disease progression. In our study, it was observed that among adults, CD4+ cell counts ranged from 518-1098, CD8+ from 312-952, whereas CD4/CD8 ratio from 0.75-2.30. Among children, both CD4+ and CD8+ cells were more and the CD4/CD8 ratio varied from 0.91-3.17. With regard to leprosy patients, we observed that CD4+ and CD8+ cell counts were lower among PB (pauci-bacillary) and MB (multi-bacillary) patients. CD4/CD8 ratio was 0.99 ± 0.28 among PB patients while the ratio was lower, 0.78 ± 0.20, among MB patients. CD4+ cell counts were raised during RR (reversal reactions) and ENL (erythema nodosum leprosum) among the PB and MB patients whereas the CD8+ cell counts were lower among PB and MB patients. CD4/CD8 ratio doubled during reactional episodes of RR and ENL. Among the HIV-negative tuberculosis (TB) patients, both the CD4+ and CD8+ cell counts were found to be less and the CD4/CD8 ratio varied between 0.53-1.75. Among the HIV-positive TB patients and HIV-positive patients, both the CD4+ and CD8+ cells were very less and ratio drops significantly. In the initial stages of infection, as CD4+ counts drop, an increase in the CD8+ cell counts was observed and the ratio declines. In full-blown cases, CD4+ cell counts were very low, 3-4 to 54 cells, CD8+ cells from 12-211 and the ratio drops too low. This study is the first of its kind in this region of the country and assumes importance since no other study has reported the values of CD4+ and CD8+ T-lymphocyte counts among patients with mycobacterial diseases (leprosy and TB), HIV infections along with normal healthy individuals of the region, and correlation with clinical presentations of patients.

Effect of lead exposure on lymphocyte subsets and activation markers.

Lead is a common environmental pollutant which has adverse effects on the immune system. We studied frequency of peripheral blood populations of CD4, CD8, and CD56 expressing cells and presence of activation marker (CD25) and CD45 isoforms by flow cytometry. Among 59 lead-exposed individuals (26 three-wheeler drivers, 33 battery workers) and 21 healthy controls, blood lead levels were 6.7 +/- 4.5 microg/dL, 132 +/- 103 microg/dL, and 4.5 +/- 2.0 microg/dL, respectively. The percentage of CD4(+) cells was significantly lower (P < 0.001) and of CD45RA(+) cells higher (P < 0.05) in both lead-exposed groups as compared to controls. There was a significant negative correlation between the CD4(+) cell percentage and blood lead levels and length of exposure. Our data highlight the adverse effect of lead on immune cells which may have serious consequences for those with chronic exposure to lead.

In vitro effect of fluoroquinolones against Mycobacterium tuberculosis isolates from Agra & Kanpur region of north India.

BACKGROUND & OBJECTIVE: Fluoroquinolones (FQs) are important drugs used for treatment of drug resistant tuberculosis and are also now being considered as first line drugs to shorten the duration of treatment of tuberculosis (TB). In order to find out useful FQs for treatment of tuberculosis, the comparative efficacy of five FQs, namely, ofloxacin (OFL), ciprofloxacin (CIP), sparfloxacin (SPX), gatifloxacin (GAT) and levofloxacin (LEVX) was studied against Mycobacterium tuberculosis (MTB) isolates obtained from both treated and untreated patients from Agra and Kanpur regions of north India. METHODS: A total of 162 MTB isolates [including 110 MTB isolates obtained from untreated patients (Cat-I) and 52 isolates from treated patients (Cat-II)] were tested for their susceptibilities to FQs using standard minimum inhibitory concentration (MIC) method on Löwenstein-Jensen medium. RESULTS: Keeping in view the therapeutically achievable drug levels, it was found that in Cat-I 97.2 per cent (107/110) isolates were sensitive to GAT, 89 per cent (98/110) to LEVX at 1 microg/ml whereas 92.7 per cent (102/110) isolates were inhibited by OFL at 2 microg/ml and 73.6 per cent (81/110) to SPX at 0.5 microg/ml. Only 63.6 per cent (70/110) isolates were found to be sensitive to CIP at 2 microg/ml which increased to 89 per cent (98/110) at 4 microg/ml (higher than achievable peak serum level). On the other hand, among 52 isolates for Cat-II, 37 (71.2%) were found to be sensitive to GAT and 33 (63.5%) to LEVX at 1 microg/ml concentration, 28 (53.8%) to SPX at 0.5 microg/ml whereas 33 (63.5%) and 24 (46.2%) isolates were found to be sensitive to OFL and CIP at 2 microg/ml, respectively. INTERPRETATION & CONCLUSION: It appears that GAT has higher activity against MTB isolates followed by OFL, LEVX and SPX whereas CIP showed the lowest activity. GAT was also found to be the most effective FQ against multi-drug resistant (MDR) isolates both from Cat-I and Cat-II patients. Thus, except CIP, other FQs showed potential to be included in the treatment regimens of tuberculosis including MDR-TB.

Identification of environmental mycobacteria isolated from Agra, north India by conventional & molecular approaches.

BACKGROUND & OBJECTIVE: Several environmental mycobacteria have been shown to be important human pathogens linked to immunomodulation especially in relation to effect on vaccination. Hence identification of mycobacteria to the species level is not only relevant to patient management but also to understand epidemiology of mycobacterial diseases and effect on vaccination. We undertook this study to assess the usefulness of various conventional and molecular methods in identification of environmental mycobacterial species from Agra, north India. METHODS: One hundred nineteen isolates of environmental mycobacteria were grown from 291 (116 soil and 175 water) samples. These isolates were identified by standard biochemical tests, and a simple, rapid and cost-effective in-house developed gene amplification restriction analysis targeting 16S-23S rRNA spacer and flanking region and 16S rRNA sequencing. RESULTS: Biochemical tests could clearly identify only 68.1 per cent (81/119) of isolates to species level. An in-house developed gene amplification--restriction analysis method could confirm the identity of 102 of 119 (85.7%) isolates and the remaining 17 isolates (14.3%) were confirmed by 16S rRNA sequencing also. These 119 environmental mycobacterial isolates, included several potentially pathogenic species such as M. fortuitum, M. chelonae, M. avium, M. marinum, M. manitobense, M. kansasii and others belonged to nonpathogenic species, M. terrae, M. smegmatis and M. flavescens. M. chelonae was isolated from water samples only whereas M. fortuitum was isolated from both water as well as soil samples. INTERPRETATION & CONCLUSION: The in-house developed gene amplification restriction analysis method though failed to accurately identify 14.3 per cent of isolates, facilitated rapid differentiation of most of environmental mycobacteria including potential pathogens from this area and thus would have diagnostic potential in cases with NTM infections. This combination strategy using PCR-RFLP and 16S rRNA sequencing may be useful for characterization of mycobacteria from similar environmental settings from other parts of world.

Isolation of Mycobacterium bovis & M. tuberculosis from cattle of some farms in north India--possible relevance in human health.

BACKGROUND & OBJECTIVE: Infection due to Mycobacterium bovis typically occurs in cattle and animals transmit infection to each other. The choice of appropriate clinical specimen is very important for isolation of M. bovis and M. tuberculosis from cattle. The present study reports the isolation of M. tuberculosis and M. bovis from different types of specimens from cattle suspected to be suffering from tuberculosis in certain organized cattle farms in north India. METHODS: A total of 768 specimens (heparinized or EDTA containing blood (162), fine needle aspirates from prescapular lymph gland (PSLG,160), milk (154), pharyngeal swab (PhS, 98), rectal pinch (RP, 97) and faecal sample (97) from 161 cattle of organized cattle farms in north India suspected to be suffering from tuberculosis were analyzed. After decontamination by modified Petroff's method isolation of M.tuberculosis complex was done on Lowenstein-Jensen medium (with and without pyruvate). The culture isolates were identified as M. tuberculosis and M. bovis on the basis of biochemical tests. RESULTS: A total of 54 M. tuberculosis complex isolates were obtained, of them 40 were identified as M.bovis and 14 as M. tuberculosis. M.bovis were isolated from 12 of 38 animals in group A (Tuberculin +ve with signs of tuberculosis), 7 of 37 animals in group B (Tuberculin +ve and apparently healthy), 9 of 21 group C animals in (Tuberculin -ve with clinical signs of tuberculosis), 4 of 26 animals in group D (Tuberculin -ve and apparently healthy), 4 of 27 group E animals (having non-mycobacterial infection) and 4 of 12 animals in group F (having clinical signs such as debilitated condition, cough, decreasing milk production, etc). Maximum number of M. bovis (19/40, 47.5%) and M. tuberculosis (5/14, 35.7%) isolates were grown from prescapular lymph gland biopsy (PSLG) followed by blood from which 9/40 (22.5%) M. bovis and 4/14 (28.5%) M. tuberculosis were isolated. M. bovis [6/40(15%)] and M. tuberculosis [4/14(28.5%)] were also isolated from milk. Only 3/40 (7.5%) isolates of M.bovis could be isolated from 97 rectal pinch followed by 98 pharyngeal swab 2/40 (5%) and 97 fecal samples 1/40 (2.5%) while 1/14 (7.1%) M.tuberculosis isolates were obtained from pharyngeal swab. INTERPRETATION & CONCLUSION: Among the samples analyzed, PSLG was found to be most suitable specimen for isolation of M. tuberculosis complex from cattle and is thus of diagnostic importance. M. bovis in milk indicates the need to investigate the transmission to human in such settings. Isolation of M. bovis and/or M. tuberculosis from apparently healthy cattle indicates sub-clinical infection in the herd. Further, isolation of a significant number of M. tuberculosis from cattle suggests possible human-to-cattle transmission which need to be confirmed by prospective studies including tools like DNA fingerprinting.

Diagnostic potential of Ag85C in comparison to various secretory antigens for childhood tuberculosis.

Childhood tuberculosis is difficult to diagnose. A rapid, simple and relatively inexpensive diagnostic test will be crucial to future control efforts. Therefore, efficacy and diagnostic potential of different secretory antigens of Mycobacterium tuberculosis (CFP-10, Ag85complex, Ag85 A, B, C) and their combinations along with ESAT-6 in the detection of antibody profiles of childhood tuberculosis cases were evaluated using ELISA technique and reactivity was compared with the gold standards (smear, culture and IS6110 targeted PCR). In the present study, 88 fresh, untreated childhood tuberculosis (TB) cases, 17 children undergoing anti-tubercular therapy, 17 children having disease other than TB and 25 healthy children were included. ROC curve analysis was used to calculate the sensitivity and specificity of each antigen for antibody detection. Ag85C was found to be showing highest sensitivity of 89.77% and specificity of 92% among all the antigens used (P < 0.0001). Positivity with antigen was 95% in smear and culture negative patients. Antibody reactivity was noted in 92.62% of patients who were positive for IS6110 by PCR. Cocktail of all the antigens showed 67.1% sensitivity and 80% of specificity. Sensitivity of 29.55%, 57.95%, 64.77% and specificity of 80%, 72%, 64% was observed using CFP-10, Ag85complex and Ag85B. Low reactivity of 31.82% in patients and least specificity of 24% was noted with Ag85A. Our finding demonstrates the potential of Ag85C in the detection of antibody in childhood TB cases and this antigen showed good concordance with PCR positivity.

Detection of viable Mycobacterium leprae in soil samples: insights into possible sources of transmission of leprosy.

Leprosy has ceased to be a public health problem world wide, after the successful implementation of effective chemotherapy (MDT) and use of control measures. However, new cases of leprosy continue to occur. Mycobacterium leprae cannot be grown in any acceptable culture medium and besides the wild armadillos, there is no known animal reservoir for leprosy. The transmission of leprosy is believed to be due to a large extent by droplet discharge of bacilli through nose and mouth and to a lesser extent by direct contact of susceptible host with a patient for long duration. The exact role of the environment in the transmission dynamics is still speculative. In the present study, we have tried to detect viable M. leprae from soil samples in endemic areas by using molecular methods. Eighty soil samples were collected from villages of this area, DNA and RNA of M. leprae extracted and identified using specific M. leprae primers. PCR amplification was done and real-time RT-PCR was used to detect viable M. leprae. DNA targeting the 16S region of M. leprae was detected in 37.5%, whereas M. leprae RNA targeting the same region was detected in 35% of these samples. Of the total 80 samples, 40 were collected from residential areas of leprosy patients whereas 40 samples were from no-patient areas. Fifty-five percent positivity for 16S rRNA of M. leprae was observed from the "patient" area in comparison to 15% positivity from the "no-patient" area (p < 0.001). This study thus provides valuable information of presence of viable M. leprae in soil specimens, which would be of use in investigating the transmission dynamics in leprosy.

Changing profile of disease in leprosy patients diagnosed in a tertiary care centre during years 1995-2000.

A hospital based retrospective study was carried out to determine change in the profile of disease in leprosy patients taking 1995 as baseline and compared with the profile seen in year 2000. A total of 2149 and 1703 cases were studied respectively of year 1995 and 2000. Male to female ratio slightly increased from 2.95:1 in year 1995 to 3.4:1 in year 2000. Majority of patients were of borderline type in both years. Proportion of cases with MB leprosy was nearly same in females (60.8%) and males (63.1%) in year 1995 and in year 2000 (64.8% females and 67.6% males). Proportion of highly bacillary cases has decreased over the years in females (from 20.95% in 1995 to 11.7% in year 2000, p=0.03) as well as in males (from 25% in 1995 to 15.5% in year 2000, p=0.001). Incidence of total reactions increased from 27.6% to 35.4% over the years which is significant (p<0.01). Proportion of type 1 reactions were more in reproductive age group in females in both years (p<0.05) and of type 2 reactions were significantly (p > or = 0.05) more in males in both years. Incidence of disability (both grade 1 and grade 2) was significantly more in males than in females in both years (p > or = 0.04). Grade 1 disability has significantly increased over years in females from 10.11% to 14.8%(p<0.03) as well as in males from 13.27% to 21.3%(p<0.001). Onset of reactions was associated with pregnancy/lactation in 62% of cases and with menopause in 21% of cases in 2000, which suggests strong correlation with hormonal imbalance. To conclude while leprosy incidence has declined after MDT, recognition and management of reactions in women around changes in their hormonal levels should be properly monitored for early and effective management.

Development and evaluation of real-time RT-PCR assay for quantitative estimation of viable Mycobacterium leprae in clinical samples.

Detection of live organisms by molecular methods has special significance in leprosy where causative organism can not be cultivated in vitro. Such techniques would be especially important for monitoring the progress of the disease. While real-time RT- PCR technology will be appropriate for this purpose, there is very little experience of use of such tools in leprosy. This study describes the development of a quantitative RT-PCR targeting 16S rRNA based on primers used in a semi quantitative RT-PCR and its application on clinical samples including slit scraping and biopsies. RNA was extracted from biopsies from 3 lepromatous leprosy (LL) cases and standard curve was generated by plotting crossing over point against the dilutions of input RNA quantity (number of bacilli used for RNA extraction). Real-time RT-PCR was performed for quantitative detection of live M. leprae in 28 slit (13/28 smear positive) scrappings and 32 biopsies (22/32 smear positive). Number of viable bacteria as estimated by solid stained bacilli and real-time PCR correlated (no difference p>0.05). The test achieved a theoretical analytical sensitivity limit of up to single live bacillus even considering 11.3% efficiency of RNA preparation which was calculated by spiking of known number of leprosy bacilli in non leprosy skin biopsies (PCR negative). All smear positive cases were positive by this assay. This assay appears to be a promising tool for detection and quantification of viable bacilli in selected clinical situations and should be of use even in smear negative cases also.

Leprosy scenario in Agra: epidemiological observations from rapid population survey 2004-06.

This study based on rapid survey methodology examining 17.86 lakhs population revealed that leprosy prevalence in Agra District is 6.1/10,000 during 2004-06, with 97.2% of the cases detected for the first time. Although leprosy is still endemic but all the leprosy indicators have shown positive change since last survey in 2001-03. The results seem promising to achieve elimination target (<1/10,000) since prevalence/10,000 population declined from 16.4 in 2001-03 to 6.1 in 2004-06, MB rate from 22.3 to 17.1, Mean duration of disease at detection (months) from 32.3 to 22.9, per cent new cases increased from 88.2% to 97.2% and visible disability (Grade > or = 2) rate declined from 4.8% to 2.36% over this period. The data on patients with incomplete history of treatment (prevalent) but having active disease indicate that only about 3% (31/1090) had approached the health center for treatment. Of these 31 patients, 29% defaulted from treatment and still have active disease and 75.2% (23/31) had MB disease indicating a pattern of late reporting to health system. This study suggests that repeat surveys are useful to detect cases for treatment and seems the key to achieve leprosy elimination or even eradication at district level in all endemic districts.

Serum samples from patients with mycobacterial infections cross-react with HIV structural proteins Gp41, p55 and p18.

BACKGROUND: Infection with Mycobacterium leprae is associated with a high frequency of false positive results in a variety of serological assays. Our studies have found cross-reactivity to HIV structural proteins in serum samples from leprosy patients, irrespective of the type of disease, treatment duration, age and gender and from a few patients with active TB disease. METHODS: Western blot (WB) analysis revealed that sera from HIV negative leprosy patients across the spectrum showed high reactivity with p18, Gp41 and p55 and lower reactivity with other HIV proteins. The reactivity appeared to be specific; western blot-positive samples were negative in ELISA and in several rapid tests for HIV. Cross-reactivity was not found in sera from patients with leishmaniasis or from normal healthy individuals. RESULTS: None of the WB reactive leprosy patients seroconverted to HIV positivity within 6 months to 1 year after Western blot testing. BLAST analysis revealed that envelope antigens of HIV (Gp41, Gp120 and Gp160) contained amino acid sequences similar to M. leprae ML0470, putative integral membrane protein, Rv0740, mmpL9 (M. tuberculosis). Core (gag) antigens (p18) had similarities to ML0406, but polymerase antigens (p52) had similarities to PE_PGRS (M. tuberculosis, H37Rv). Nucleotide sequence analysis, on the other hand, did not reveal any significant homology between M. leprae or M. tuberculosis and HIV. CONCLUSIONS: The occurrence of these high false-positive rates in M. leprae-infected individuals suggests a possible complication of serodiagnosis of HIV in regions where mycobacterial infections are endemic. There is a need for caution in reporting HIV infection among leprosy patients. Our observations emphasise the value of the various rapid assay kits for HIV, where this false positivity is not observed.

Seroprevalence of HIV infection among paediatric tuberculosis patients in Agra, India: a hospital-based study.

In this study which was carried over a period of 2 years, from 2003 to 2004, 270 paediatric patients with active Tuberculosis (TB) disease attending the OPD of S.N. Medical College, Agra were screened for Human Immunodeficiency Virus (HIV)-1/2 antibodies. Of these, 23 were found to be HIV-positive. Seroprevalence of HIV infection among paediatric TB patients in Agra is 8.51% (23/270). The HIV infection was found to be significantly higher, i.e. 82.61% in male children than in female children, i.e. 17.39%. Among the age groups, which were divided into < or =1, 2-5, 6-10 and 11-15 years, maximum cases of HIV-positivity, i.e. 65.22% was observed in the age group, 2-5 years of age. Among the HIV-positive children with TB, 86.75% were of pulmonary and 13.04% were of extra-pulmonary type. Among the vaccinated children, 65.22% were found to be HIV-positive, while 34.78% of the HIV-positive children were not BCG vaccinated. HIV-positive children are more likely to suffer from prolonged fever, weight loss, failure to thrive, developmental delay, stunted growth, cough, anorexia, lethargy, lower respiratory tract infections (LRTI) and hepatosplenomegaly while HIV negative are more likely to suffer from fever, diarrhoea, lymphadenitis, pallor and LRTI. 82.60% (19/23) of these TB patients had a history of positive contact with HIV, i.e. one of the parents was HIV-infected. The mode of transmission of HIV infection among paediatric TB patients was perinatal as revealed during the counselling sessions (pre-test and post-test) of both the parents.

HIV, HBV, HCV, and syphilis co-infections among patients attending the STD clinics of district hospitals in Northern India.

OBJECTIVE: The objective of the study was to assess the risk of co-infections with human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis among patients attending sexually transmitted disease (STD) clinics, antenatal clinics (ANC) and Ob-Gyn outpatients department (OPD) clinics which were part of the sentinel surveillance program. METHODS: A serological screening was carried out during the period August-November 2002 to assess the risk of infection with HIV-1/2, and co-infection with HBV, HCV, and syphilis among the outpatients attending STD clinics, Ob-Gyn OPD clinics, and ANC of three district hospitals (Agra, Etawah, and Farrukhabad) of Uttar Pradesh state in Northern India. Unlinked and coded serum samples received from 863 patients (635 females and 228 males) were screened by laboratory tests commonly used for laboratory diagnosis of HIV, HBV, HCV, and syphilis. RESULTS: Among the 863 samples serological reactivity was detected for HIV-1/2 in 21 (2.4%), HBV in 25 (2.9%), HCV in nine (1.0%), and syphilis in 47 (5.4%). The incidence of HBV was higher among males than females, i.e. 10/228 (4.4%) versus 15/635 (2.4%). Co-infection was observed for HIV-HBV in two (0.2%), HBV-HCV in one (0.1%), and HIV-syphilis in one (0.1%). None were found to have co-infection with HIV-HCV, HBV-syphilis, and HCV-syphilis. Age, sex, literacy level, occupation, locality, migration, and presence of different sexually transmitted infections did not significantly influence the rate of HIV positives. CONCLUSION: A substantial percentage of the outpatients seen in the clinics of the district hospital in Uttar Pradesh harbor HIV and viral hepatitis infections, which otherwise would remain undiagnosed without serological screening.

Seroprevalence of HIV infection among tuberculosis patients in Agra, India--a hospital-based study.

In this study which was carried over a period of 4 years, from 2001 to 2004, 600 adult patients with active TB disease attending the OPD of TBDTC, Agra, were screened for HIV-1/2 antibodies. Of these, 26 were found to be HIV-positive. Seroprevalence of HIV infection among adult TB patients in Agra is 4.3% (26/600). The HIV infection was found to be more in females, i.e. 7.95% (7/88) than in males, 3.71% (19/512). HIV-positivity of 5% was observed in the age groups, 15-24 and 25-34 years, i.e. 3/60 and 13/260, respectively. Among HIV-positive TB patients, 4.2% (22/524) were of pulmonary and 5.3% (4/76) were of extra-pulmonary type. A total of 3.04% (6/197) of HIV-positive TB patients were PPD positive and 4.96% (20/403) were PPD negative and bacillary positivity was 4.4% (15/340) and bacillary negativity was 4.2% (11/260). A total of 3.5% (18/515) of TB patients had a history of positive contact, i.e. spouse or one of the family members was HIV-infected. The difference in signs and symptoms among the HIV positive and HIV negative TB patients was found to be statistically significant.
