RESUMO

We examined associations with HIV recent infection and estimated transmitted drug resistance (TDR) prevalence among 3345 men at sexually transmitted infection clinics in Mumbai (2002-2005). HIV seroincidence was 7.92% by the BED-CEIA and was higher at a clinic located near brothels (12.39%) than at a hospital-based clinic (3.94%). HIV recent infection was associated with a lifetime history of female sex worker (FSW) partners, HSV-2, genital warts, and gonorrhea. TDR prevalence among recent infection cases was 5.7%. HIV testing services near sex venues may enhance case detection among high-risk men who represent a bridging population between FSWs and the men's other sexual partners.

RESUMO

Hospital-based rotavirus surveillance was carried out in Mumbai during 2005-2009. An isolate (B08299) with a rare genotype combination (G11P[25]) was detected. The present study was undertaken to characterize the complete genome of the isolate. B08299 exhibited a G11-P[25]-I12-R1-C1-M1-A1-N1-T1-E1-H1 genotype constellation. Phylogenetic analysis of the 11 gene segments of B08299 revealed that the VP2 and NSP5 genes of B08299 had a human origin, while the VP6 gene represented an I12 genotype of obscure origin. The remaining six genes formed a lineage distinct from human and porcine rotaviruses within genotype 1. Analysis of the structural and non-structural genes suggested that B08299 has evolved by gene reassortment. Our findings provide further evidence that interspecies transmission is an important mechanism involved in the evolution and genetic diversity of human rotaviruses in nature.

RESUMO

Mucocutaneous and cutaneous candidiasis, though common in children, is often under-reported. The prevalence of Candida dubliniensis in causing these infections in this age group is also largely unknown. A prospective epidemiological cross-sectional study for candidiasis was performed in paediatric patients clinically suspected of candidiasis with oropharyngeal lesions (75 patients), cutaneous lesions (18 patients) and lesions at both sites (2 patients). Candida species were identified by conventional tests. For C. dubliniensis, chlamydospore production, growth on tobacco agar and growth at 45 °C were performed. Nine isolates were confirmed at a reference centre. The rates of candidiasis were 77.3 % (58 out of 75 patients clinically suspected of candidiasis) and 83.3 % (15/18) in oropharyngeal and cutaneous lesions respectively, and 1 of the 2 children with lesions at both sites was diagnosed as having chronic mucocutaneous candidiasis due to C. dubliniensis. The commonest species isolated was Candida albicans, in 41 (70.7 %) patients with oropharyngeal candidiasis and 11 (73.3 %) with cutaneous lesions; C. dubliniensis was isolated from 11 and 3 children respectively. In the paediatric population, C. albicans predominates in mucocutaneous and cutaneous candidiasis, with C. dubliniensis also contributing substantially.

RESUMO

BACKGROUND: Multidrug resistant Acinetobacter infection has emerged as an important pathogen in neonatal sepsis in the recent years causing morbidity as well as mortality. MATERIALS AND METHODS: A retrospective analysis was performed over a one and a half year period of all neonates admitted with sepsis in our neonatal intensive care unit (NICU), who developed Acinetobacter infection and to identify mortality-associated risk factors in these neonates. RESULTS: Incidence of neonatal septicaemia due to Acinetobacter species was 9.18%. All were cases of early onset sepsis. Predominant species isolated was Acinetobacter baumanii (67.5%). The major symptoms were lethargy and poor feeding. The major signs were tachypnoea, rib retraction, and respiratory distress. The major fetal risk factors were low birth weight and prematurity. Overall, 53.75% were multidrug resistant (MDR) Acinetobacter. Resistance to more than two drugs (MDR) was statistically significant in A. baumanii as compared with nonbaumanii. Overall mortality due to Acinetobacter neonatal sepsis was 20%. Septicemia due to A. baumanii was associated with higher mortality than those due to nonbaumanii isolates. Lethargy, tachypnoea, rib retraction, tachycardia, respiratory distress, and mechanical ventilation were significant predictors of mortality. CONCLUSION: Multidrug resistant Acinetobacter infection is fatal, particularly in premature and low birth weight neonates. Therefore, an effective infection control policy and rational antibiotic use are mandatory in neonatal intensive care areas of each hospital in order to control Acinetobacter infection and improve outcome.

RESUMO

BACKGROUND: India accounts for 22% of the 453,000 global rotavirus deaths among children <5 years annually. The Indian Rotavirus Strain Surveillance Network provides clinicians and public health partners with valuable rotavirus disease surveillance data. Our analysis offers policy-makers an update on rotavirus disease burden with emphasis on regional shifts in rotavirus strain epidemiology in India. METHODS: Children <5 years requiring hospitalization for acute gastroenteritis were selected from 10 representative hospitals in 7 cities throughout India between November 2005 through June 2009. We used a modified World Health Organization protocol for rotavirus surveillance; stool specimens were collected and tested for rotavirus using enzyme immunoassay and reverse-transcription polymerase chain reaction. RESULTS: A total of 7285 stool specimens collected were tested for rotavirus, among which 2899 (40%) were positive for rotavirus. Among the 2899 rotavirus detections, a G-type could not be determined for 662 (23%) and more than one G type was detected in 240 (8%). Of 1997 (69%) patients with only one G-type, the common types were G1 (25%), G2 (21%), G9 (13%), and G12 (10%). The proportion of rotavirus infections attributed to G12 infections rose from 8% to 39% in the Northern region and from 8% to 24% in the Western region. CONCLUSIONS: This study highlights the large, ongoing burden of rotavirus disease in India, as well as interesting regional shifts in rotavirus strain epidemiology, including an increasing detection of G12 rotavirus strains in some regions. While broad heterotypic protection from rotavirus vaccination is expected based on pre- and post-licensure data from other settings, effectiveness assessments and rotavirus strain monitoring after vaccine introduction will be important.

RESUMO

A survey for transmitted HIV drug resistance (HIVDR) was conducted according to WHO guidelines among clients newly diagnosed with HIV-1 infection at two voluntary counseling and testing centers (VCTC) in Mumbai. HIVDR testing was performed using the ViroSeq RT-PCR method (Abbott). Out of 50 successfully amplified and sequenced specimens, analysis of the first 34 consecutively collected specimens revealed no nucleoside reverse transcriptase inhibitor, nonnucleoside reverse transcriptase inhibitor, or protease inhibitor mutations from the 2007 WHO list of mutations for surveillance of transmitted HIVDR, indicating that the prevalence of transmitted HIVDR to all three drug classes was <5% among recently infected VCTC clients in Mumbai. The phylogenetic analysis revealed that all samples belonged to HIV-1 subtype C. Continued ART program monitoring and further evaluation of transmitted HIV drug resistance in coming years are essential in Mumbai as well as in other regions of the country in which ART is being scaled up rapidly.

RESUMO

PURPOSE: Study on the microbiological assessment of cadaver skin grafts was undertaken in the Skin Bank at the Department of Surgery in L.T.M. Medical College and Hospital, Mumbai, India. PROCEDURE: Microbiology of the skin grafts was studied immediately on receipt and after antibiotic treatment. The antimicrobial and antifungal agents used were crystalline penicillin, gentamicin, amikacin, ceftazidime and amphotericin B. FINDINGS: Escherichia coli, Staphylococcus aureus and Candida species were the predominant microorganisms isolated on pre-processing cultures from cadaver skin grafts. Seventy percent of pre-processing cultures showed growth. After first cycle antibiotic treatment, 52.4% of grafts showing growth became sterile. Growth of Klebsiella pneumoniae persisted in two cases, even after 2nd cycle of antibiotic treatment. After the use of antifungal, 57.1% of those showing fungal growth became sterile. CONCLUSION: Various antibiotics and antifungals can be used in order to minimize the discard rate of skin grafts.

RESUMO

Nine hundred and forty two serum samples from clinically suspected cases of leptospirosis admitted in Lokmanya Tilak Municipal General Hospital, Mumbai during July-September 2005 were tested by LeptoTek Dri-dot/Leptocheck. One hundred and sixty five positive sera by these tests were sent to I.R.R., Mumbai, for detection of leptospira IgM antibodies by ELISA (PanBio). Eighty seven positive sera were also sent to B.J. Medical College, Pune, for microscopic agglutination test (MAT) for serovar identification. Seropositivity with LeptoTek Dri-dot/Leptocheck was 34.3%. Adults and males predominated. All patients were febrile. The commonest presentation in adults was jaundice (81.4%), followed by oliguria (37.6%). In children, myalgia was commonest (75.6%), followed by conjunctival suffusion (54.7%). IgM ELISA positivity was 69.1% and MAT positivity was 29.9%. Commonest serovar detected in this geographical area was Leptospira icterohaemorrhagiae (42.9%), followed by L. bataviae, L. tarassovi, and L. pomona . Considering at least two of the above three serological tests positive, 127 cases could be diagnosed and only 89.8% of them could be diagnosed by ELISA and rapid test. Therefore, along with rapid serological tests, IgM ELISA should be routinely done for laboratory diagnosis of leptospirosis.

RESUMO

White piedra is a superficial fungal infection of the hair shaft, caused by Trichosporon beigelii . We report two cases of white piedra presenting as brown palpable nodules along the hair shaft with a fragility of scalp hairs. T. beigelii was demonstrated in hair culture of both the patients and T. ovoides as a species was confirmed on carbohydrate assimilation test. The first patient responded to oral itraconazole and topical ketoconazole, with a decrease in the palpability of nodules and fragility of scalp hairs at the end of two months.

RESUMO

We describe the same-sex partnerships and sexual risk behavior of men attending sexually transmitted infection (STI) clinics in Mumbai, India. The HIV prevalence among 2,381 men sampled was 14%; 62% had a documented STI. Almost all men reported sex with women; additionally, 13% also reported having sex with other men, 13% reported sex with Hijras (male-to-female transgenders), and 11% had sex with all 3 genders. Men who had sex with men and/or Hijras as well as women, reported having greater numbers of partners, including female sex workers (FSW), and were more likely to engage in insertive anal and oral sex with women. The prevalence of HIV was higher among men having sex with Hijras (14%) or with all 3 genders (13%) than among men having sex with men and women (8%). A high proportion of men who attend STI clinics in Mumbai are behaviorally bi- or tri-sexual and have multiple partners with whom they engage in risky sex. STI/HIV prevention programs should not assume that men only have sex with women.

RESUMO

Pooling urogenital specimens for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae by nucleic acid amplification tests is an attractive alternative to individual testing. As pooling can reduce the costs of testing as well as labor, it has been advocated for use in resource-poor settings. However, it has neither been widely adopted nor evaluated for use in developing countries. We evaluated the practical use of pooling first-catch urine (FCU) specimens for the detection of C. trachomatis and N. gonorrhoeae from 690 men in Mumbai, India, by PCR. FCU, urethral smears, and swabs were collected from men seen at two sexually transmitted infection (STI) clinics. All laboratory testing was done at the Lokmanya Tilak General Hospital. Gram stain smears and culture isolation for N. gonorrhoeae were performed. Each FCU was tested individually and in pools using the Roche Amplicor PCR for C. trachomatis and N. gonorrhoeae with an internal control for inhibition. Specimen pools consisted of aliquots from five consecutively processed FCUs combined into an amplification tube. An optical density reading of > or =0.20 indicated a pool for which subsequent testing of individual samples was required. Prevalence by PCR on single specimens was 2.2% (15/690) for C. trachomatis and 5.4% (37/690) for N. gonorrhoeae. Compared to individual FCU results, pooling for C. trachomatis and N. gonorrhoeae had an overall sensitivity of 96.1% (50/52). Specificity was 96.5% (83/86) in that three pools required single testing that failed to identify a positive specimen. Pooling missed two positive specimens, decreased the inhibition rate, and saved 50.3% of reagent costs. In this resource-limited setting, the use of pooling to detect C. trachomatis and N. gonorrhoeae by PCR proved to be a simple, accurate, and cost-effective procedure compared to individual testing.

RESUMO

OBJECTIVE: We investigated whether men who were under the influence of alcohol when visiting female sex workers (FSW) were at greater risk for sexually transmitted infections (STI) and human immunodeficiency virus (HIV). STUDY: A cross-sectional analysis using baseline data from a randomized controlled trial of an HIV prevention intervention for high-risk men in Mumbai, India. RESULTS: The overall HIV prevalence among 1741 men sampled was 14%; 64% had either a confirmed STI or HIV; 92% reported sex with an FSW, of whom 66% reported having sex while under the influence of alcohol (SUI). SUI was associated with unprotected sex (odds ratio [OR]: 3.1; 95% confidence interval [CI], 2.3-4.1), anal sex (OR: 1.5; 1.1-2.0), and more than10 FSW partners (OR: 2.2; 1.8-2.7). SUI was independently associated with having either an STI or HIV (OR: 1.5; 1.2-1.9). CONCLUSION: Men who drink alcohol when visiting FSWs engage in riskier behavior and are more likely to have HIV and STIs. Prevention programs in India need to raise awareness of this relationship.

RESUMO

The increasing prevalence of HIV infection in urban India together with limited financial resources necessitates judicious HIV testing. This prospective study was undertaken to determine the utility of selective screening for HIV infection based on five clinical risk factors reported in African children. The study was conducted at the Departments of Paediatrics and Microbiology, LTMG Hospital, Bombay, India between September 1998 and 2000. The children were enrolled after taking informed consent from their parents. The HIV seroprevalence rate was determined in children (aged 1 month to 12 years) consecutively admitted with severe malnutrition, serious pyogenic infections (pneumonia, pyogenic meningitis, septicaemia), disseminated tuberculosis, chronic diarrhoea and oral candidiasis, present either singly or in combination. Children above 18 months of age were diagnosed as being infected with HIV if they tested positive by two different HIV enzyme-linked immunosorbent assay (ELISA) tests. In children less than 18 months of age the diagnosis of HIV infection was made if they were ELISA positive and also fulfilled the WHO criteria for symptomatic HIV infection. Of a total 204 children (110 male, 94 female) screened, 24 (11.8 per cent) were diagnosed as HIV-infected. The HIV seropositive rate was highest in children having oral candidiasis (40.6 per cent), followed by chronic diarrhoea (18.2 per cent), disseminated tuberculosis (16.2 per cent), severe malnutrition (14.4 per cent), and serious pyogenic infections (11.2 per cent). Only the presence of oral candidiasis was a significant independent risk factor for predicting HIV infection (p < 0.0001). However, as the number of risk factors concomitantly present increased, the chances of the child being infected with HIV also increased significantly (p < 0.001). Our study shows that clinically-directed selective screening does have a practical role in diagnosing HIV infection in a resource-poor setting.
