Developing a researchable question is one of the challenging tasks a researcher encounters when initiating a project. Both, unanswered issues in current clinical practice or when experiences dictate alternative therapies may provoke an investigator to formulate a clinical research question. This article will assist researchers by providing step-by-step guidance on the formulation of a research question. This paper also describes PICO (population, intervention, control, and outcomes) criteria in framing a research question. Finally, we also assess the characteristics of a research question in the context of initiating a research project.

Given the longevity achievable with current prophylactic and therapeutic strategies for persons with HIV infection, quality of life (QOL) has emerged as a significant medical outcome measure, and its enhancement has an important goal. This review highlights the relevance and complexity of physical, psychological, and social factors as determinants of health-related quality of life in HIV-infected persons. Existing data suggest that physical manifestations, antiretroviral therapy, psychological well-being, social support systems, coping strategies, spiritual well-being, and psychiatric comorbidities are important predictors of QOL in this population. Consequently, the impact of HIV infection on the dimensions of QOL, including physical and emotional well-being, social support systems, and life roles, has emerged as a key issue for persons infected with HIV.

Randomized double blind placebo control studies, the "Gold Standard" in intervention based studies

Studies follow a hierarchy in terms of the quality of evidence that they can provide. Randomized double blind placebo control (RDBPC) studies are considered the "gold standard" of epidemiologic studies. And the same is discussed at length in this paper taking example of a real journal article employing this study design to answer the research question; "Does once daily dose of Valacyclovir reduce the risk of transmission of genital herpes in a susceptible partner?" RDBPC studies remain the most convincing research design in which randomly assigning the intervention can eliminate the influence of unknown or immeasurable confounding variables that may otherwise lead to biased and incorrect estimate of treatment effect. Also, randomization eliminates confounding by baseline variables and blinding eliminates confounding by co-interventions, thus eliminating the possibility that the observed effects of intervention are due to differential use of other treatments. The best comparison is placebo control that allows participants, investigators and study staff to be blinded. The advantage of trial over an observational study is the ability to demonstrate causality. Hope, this will be useful to neophyte researchers to understand causal hierarchy when critically evaluating epidemiologic literature.

Adolescent HIV/AIDS: Issues and challenges
Smriti Naswa, YS Marfatia
January-June 2010, 31(1):1-10
DOI

PMID
:21808429
Adolescence (10- 19 years) is a phase of physical growth and development accompanied by sexual maturation, often leading to intimate relationships. Adolescent HIV/AIDS is a separate epidemic and needs to be handled and managed separately from adult HIV. The adolescents can be subdivided into student, slum and street youth; street adolescents being most vulnerable to HIV/AIDS. Among various risk factors and situations for adolescents contracting HIV virus are adolescent sex workers, child trafficking, child labor, migrant population, childhood sexual abuse, coercive sex with an older person and biologic (immature reproductive tract) as well as psychological vulnerability. The most common mode of transmission is heterosexual, yet increasing number of perinatally infected children are entering adolescence. This is due to "bimodal progression" (rapid and slow progressors) among the vertically infected children. Clinically, the HIV infected adolescents present as physically stunted individuals, with delayed puberty and adrenarche. Mental illness and substance abuse are important co-morbidities. The disclosure and declaration of HIV status to self and family is challenging and guilt in sexually infected adolescents and tendency to blame parents if vertically affected need special consideration and proper counseling. Serodiscordance of the twins and difference in disease progression of seroconcordant twins are added causes of emotional trauma. Treatment related issues revolve around the when and what of initiation of ART; the choice of antiretrovirals and their dosages; issues related to long term ADRs; sense of disinhibition following ART commencement; adherence and resistance.

Knowledge and attitude about sexually transmitted infections other than HIV among college students
Nagesh Tumkur Subbarao, A Akhilesh
January-June 2017, 38(1):10-14
DOI
:10.4103/0253-7184.196888
PMID
:28442798
Background:
Sexually transmitted infections (STIs) are the infections which are mainly transmitted through sexual intercourse.Young individuals in the age group of 16 to 24 years are considered to be at more risk for STIs compared to older adults. Young individuals are more likely to practice unprotected sex and have multiple sexual partners. If the STIs are not treated adequately, it can lead to various complications.Most of the people may be aware about HIV/AIDs because of the awareness created by media and the government programs, however knowledge about STIs other than HIV/AIDS is low in the developing countries.
Materials and Methods:
This study was a descriptive cross sectional study to assess the knowledge, awareness and attitude of college students about STIs other than HIV. A total of 350 engineering students from various semesters were included in the study. They were asked to fill up an anonymous questionnaire.
Results:
Two hundred and fifty six (73%) males and 94 (27%) females participated in the study. 313 (90%) students had heard about sexually transmitted infections (STIs) and 223 (64%) students had heard about STIs other than HIV. 99% of students knew about HIV where as less than 50% of students knew about other STIs. Teachers, internet and media were the source of information for most of the participants. Almost 75% of the students knew about the modes of transmission of STIs. Less than 50% of the participants knew about the symptoms of STIs and complications. Also attitude of the students towards sexual health and prevention of STIs was variable.
Conclusion:
The findings of our study shows that it is important to orient the students about sexual health and safe sexual practices as it will go a long way in prevention and control of STIs. Also the morbidities and complications associated with STIs can be prevented.

Critical appraisal skills are essential to informed decision-making
Rahul Mhaskar, Patricia Emmanuel, Shobha Mishra, Sangita Patel, Eknath Naik, Ambuj Kumar
July-December 2009, 30(2):112-119

Whenever a trial is conducted, there are three possible explanations for the results: a) findings are correct (truth), b) represents random variation (chance) or c) they are influenced by systematic error (bias). Random error is deviation from the 'truth' and happens due to play of chance (e.g. trials with small sample, etc.). Systematic distortion of the estimated intervention effect away from the 'truth' can also be caused by inadequacies in the design, conduct or analysis of a trial. Several studies have shown that bias can obscure up to 60% of the real effect of a healthcare intervention. A mounting body of empirical evidence shows that 'biased results from poorly designed and reported trials can mislead decision making in healthcare at all levels'. Poorly conducted and reported RCTs seriously compromise the integrity of the research process especially when biased results receive false credibility. Therefore, critical appraisal of the quality of clinical research is central to informed decision-making in healthcare. Critical appraisal is the process of carefully and systematically examining research evidence to judge its trustworthiness, its value and relevance in a particular context. It allows clinicians to use research evidence reliably and efficiently. Critical appraisal is intended to enhance the healthcare professional's skill to determine whether the research evidence is true (free of bias) and relevant to their patients.

Tenofovir-associated renal dysfunction in clinical practice: An observational cohort from western India
Ketan K Patel, Atul K Patel, Rajiv R Ranjan, Apurva R Patel, Jagdish K Patel
January-June 2010, 31(1):30-34
DOI
:10.4103/0253-7184.68998
PMID
:21808434
Background:
Tenofovir (TDF) is preferred nucleoside reverse transcriptase inhibitors (NRTI) for the treatment of human immunodeficiency virus infection because of its potency and safety. Renal toxicity with TDF use is low and comparable with other NRTI in clinical trials, but there are many case studies and small case series of renal dysfunction with TDF.
Materials and Methods:
This is an observational longitudinal cohort of patients started on a TDF-based regimen from January 2007 to April 2010. Patients were evaluated at baseline and with every follow-up visit for serum creatinine and calculated creatinine clearance (Cockroft-Gault formula). In addition to this, the patients were also subjected to test for serum potassium, phosphorous and urine examinations as and when indicated. Renal dysfunction was defined as rise in serum creatinine to more than the upper level of normal (>1.2 mg%).
Results:
Of 1,271 patients started on a TDF-containing antiretroviral treatment (ART) 83 (6.53%) developed renal dysfunction, of which 79 had impaired serum creatinine and five had Fanconi's syndrome. Renal dysfunction was more common with boosted a protease inhibitor (PI) (9.44%)-based regimen as compared to a non- nucleoside reverse transcriptase inhibitors (NNRTI) (5.01%)-based regimen (
P
= 0.003). The mean decline in creatinine clearance from baseline was 22.27 ml/min. The median time to develop renal dysfunction was 154 (15-935) days. Serum creatinine returned to normal in all the patients after stopping TDF. Five patients presented with features suggestive of Fanconi's syndrome without alteration in serum creatinine.
Conclusion:
TDF-based treatment is associated with mild but reversible renal dysfunction. Patients receiving PI/r are at a higher risk of renal dysfunction compared to those receiving NNRTI-based ART. Clinicians should be adviced to have intensive renal monitoring, including creatinine clearance, urine examination, K+ and phosphate levels at baseline and during treatment with TDF.

Exploring dynamics of anal sex among female sex workers in Andhra Pradesh
Saroj Tucker, Rama Krishna, Parimi Prabhakar, Swarup Panyam, Pankaj Anand
January-June 2012, 33(1):9-15
DOI
:10.4103/0253-7184.93787
PMID
:22529447
Objective:
The anal sex among heterosexual couples is on the rise as reported in many scientific studies. Considering that unprotected anal sex has higher risk of human immunodeficiency virus (HIV) transmission than the vaginal sex, we undertook a study to understand the anal sex practices among Female Sex Workers (FSW).
Materials and Methods:
The study was conducted among FSW attending 11 randomly selected sexually transmitted infection (STI) clinics in Bill and Melinda Gates supported targeted interventions in Andhra Pradesh. A structured questionnaire was administered to the 555 FSW attending these clinics by project clinic counselors. Informed consent was obtained from all the study participants.
Results:
Engaging in anal sex was self reported by 22% of sex workers, though demand from clients was reported to be much higher (40%). The reasons for anal sex practices included more money (61%), clout/influence of the client (45%), risk of losing client (27%), and forced sex (1.2%). Factors associated with anal sex were higher number of clients, higher duration of sex work, higher income, and older age group. Associated risks perceived by FSW were bleeding and injury to anal canal (98%) while only 28% associated it with higher HIV transmission risk. Reported Condom and lubricant use was about 88% and 39% respectively.
Conclusion:
The study shows that there is frequent anal sex, inconsistent condom and infrequent lubricant usage, economic and physical coercion, and low awareness of STI/HIV transmission risk among FSW, which have serious implications for HIV prevention programmes. There is a need to focus on anal sex education and use of lubricants along with condoms during anal sex in FSW-targeted interventions in AP.

Pattern of sexually transmitted infections and performance of syndromic management against etiological diagnosis in patients attending the sexually transmitted infection clinic of a tertiary care hospital
Shilpee Choudhry, VG Ramachandran, Shukla Das, SN Bhattacharya, Narendra Singh Mogha
July-December 2010, 31(2):104-108
DOI
:10.4103/0253-7184.74998
PMID
:21716796
Background and Objectives:
The availability of baseline information on the epidemiology of sexually transmitted infections (STIs) and other associated risk behaviors is essential for designing, implementing, and monitoring successful targeted interventions. Also, continuous analysis of risk assessment and prevalence-based screening studies are necessary to evaluate and monitor the performance of syndromic management. The aim of the present study was to document the pattern of common STIs and to evaluate the performance of syndromic case management against their laboratory diagnoses.
Materials and Methods:
Three hundred consecutive patients who attended the STI clinic of a tertiary care hospital at Delhi, with one or more of the complaints as enunciated by WHO in its syndromic approach for the diagnosis of STIs, were included as subjects. Detailed history, demographical data, and clinical features were recorded and screened for common STIs by standard microbiological methods.
Results:
The mean age was 24 years and most of the male patients were promiscuous and had contact with commercial sex workers (CSWs 63.9%). Majority came with the complaint of genital discharge (63 males; 54 females) followed by genital ulcer (61 males; 30 females). Genital herpes accounted for the maximum number of STI (86/300) followed by syphilis (71/300). The sensitivity of genital discharge syndrome (GDS) was high for Neisseria gonorrhoeae and Chlamydia trachomatis (96% and 91%, respectively) while specificity was low (76% and 72%, respectively). The sensitivity of genital ulcer syndrome for herpes simplex virus-2 (HSV-2) and Treponema pallidum was 82.65% and 81.2%, respectively, while specificity reached 99% approximately.
Conclusions:
Viral STIs constitute the major burden of the STI clinic and enhance the susceptibility of an individual to acquire or transmit HIV through sexual contact. Syndromic algorithms have some shortcomings, and they need to be periodically reviewed and adapted to the epidemiological patterns of STI in a given setting.

Viral infections in pregnancy are a major cause of morbidity and mortality for both mother and fetus. Viral STIs occur as surface infection and then gradually infect immunologically protected sites. Therefore, these are asymptomatic, hidden and hence underdiagnosed, persistent and difficult to treat. HSV, HPV, HBV, HIV and CMV (cytomegalovirus) are the common ones. Most of these are transmitted during intrapartum period. Proper screening, identification and treatment offered during prenatal period may help in preventing their complications. Twenty five percent of women with a history of genital herpes have an outbreak at some point during the last month of pregnancy. Acyclovir is the accepted efficacious and safe therapy for HSV in pregnancy. Globally, HPV infection is the most common sexually transmitted infection. Neonatal transmission can occur in the absence of clinically evident lesions. HPV 6 or 11 may lead to Juvenile Onset Recurrent Respiratory Papillomatosis (JORRP). TCA, liquid nitrogen, laser ablation or electrocautery can be used to treat external genital HPV lesions at any time during pregnancy. Cesarean section is recommended only if the lesions are obstructing the birth canal. Mother to child transmission (MTCT) in HIV accounts for 15-30% during pregnancy and delivery, and a further 5-20% of transmission occurs through breastfeeding. HBV infection during pregnancy does not alter the natural course of the disease. In women who are seropositive for both HBsAg and HBeAg, vertical transmission is approximately 90%. Pregnancy is not a contraindication for HBV vaccination. Cytomegalovirus (CMV) is the most common intrauterine infection. Cytomegalic inclusion disease (CID) is the most severe form of congenital CMV infection. Treatment is supportive.

Genital human papillomavirus (HPV) infection is the most common sexually transmitted infection with an estimated worldwide prevalence of 9-13% and approximately 6 million people being infected each year. Mostly acquired during adolescence or young adulthood, HPV presents clinically as anogenital warts and may progress to precancerous lesions and cancers of the cervix, vagina, vulva, penis and anus, and oropharynx. HPV infection is considered to contribute to almost 100% cervical cancers and at least 80% of anal and 40-60% of vulvar, vaginal, and penile cancers. At present, two prophylactic HPV vaccines are commercially available and both are prepared from purified L1 structural proteins. These proteins self-assemble to form virus-like particles that induce a protective immunity. Gardasil
®
is a quadrivalent vaccine against HPV types 6, 11, 16, and 18 and is recommended for use in females 9-26 years of age, for the prevention of cervical, vulvar, and vaginal cancers and intraepithelial neoplasia and condyloma acuminata and recently for vaccination in boys and men 9-26 years of age for the prevention of genital warts. Cervarix™ is a bivalent vaccine approved for the prevention of cervical cancer and precancerous lesions caused by HPV 16 and 18, in females 10-25 years. HPV vaccines are safe and efficacious against type-specific HPV-induced anogenital warts, precancerous lesions, and cervical cancer. The vaccines are most effective when given before the onset of sexual activity and provide long-term protection. Effective vaccination coverage in young adolescent females will substantially reduce the incidence of these anogenital malignancy-related morbidity and mortality. There is need to generate India-specific data on HPV epidemiology and HPV vaccination efficacy as well as continue worldwide surveillance and development of newer vaccines.

Lichen sclerosus et atrophicus is an acquired chronic inflammatory dermatosis commonly affecting the vulvar and perianal regions. It is associated with an increased risk of vulvar cancer even though it is not a premalignant condition itself. The true precursor of cancer associated with lichen sclerosus (LS) is vulvar intraepithelial neoplasia (VIN), differentiated type. The diagnosis is usually clinical, but in some cases, a biopsy can be performed, especially to exclude VIN or cancer. All females with anogenital LS can be offered clobetasol propionate 0.05% ointment on a regimen for 3 months (once a day for a month, followed by alternative days for a month, and then, twice weekly for a month), combined with a soap substitute and a barrier preparation.

Pre-exposure prophylaxis (PrEP) is an experimental approach to HIV prevention and consists of antiretroviral drugs to be taken before potential HIV exposure in order to reduce the risk of HIV infection and continued during periods of risk. An effective PrEP could provide an additional safety net to sexually active persons at risk, when combined with other prevention strategies. Women represent nearly 60% of adults infected with HIV and PrEP can be a female-controlled prevention method for women who are unable to negotiate condom use. Two antiretroviral nucleoside analog HIV-1 reverse transcriptase inhibitor drugs are currently under trial as PrEP drugs, namely tenofovirdisoproxilfumarate (TDF) alone and TDF in combination with emricitabine (FTC), to be taken as daily single dose oral drugs. There are 11 ongoing trials of ARV-based prevention in different at risk populations across the world. The iPrex trial showed that daily use of oral TDF/FTC by MSM resulted in 44% reduction in the incidence of HIV. This led to publication of interim guidance by CDC to use of PrEP by health providers for MSM. Few other trials are Bangkok Tenofovir Study, Partners PrEP Study, FEM-PrEP study, and VOICE (MTN-003) study. Future trials are being formulated for intermittent PrEP (iPrEP) where drugs are taken before and after sex, "stand-in dose" iPrEP, vaginal or rectal PrEP, etc. There are various issues/concerns with PrEP such as ADRs and resistance to TDF/FTC, adherence to drugs, acceptability, sexual disinhibition, use of PrEP as first line of defense for HIV without other prevention strategies, and cost. The PrEP has a potential to address unmet need in public health if delivered as a part of comprehensive toolkit of prevention services, including risk-reduction, correct and consistent use of condoms, and diagnosis and treatment of sexually transmitted infections.

Prozone phenomenon is a false negative response resulting from high antibody titer which interferes with formation of antigen- antibody lattice, necessary to visualize a positive flocculation test. We present a case of secondary syphilis who presented to us with features of contact irritant dermatitis. She initially tested non- reactive for VDRL testing but tested positive with higher dilution. The prozone phenomenon is attaining importance because of increasing prevalence of Acquired immune deficiency syndrome. So one needs to be familiar with the occurrence of prozone phenomenon.

In many parts of the world particularly sub-Saharan Africa, congenital syphilis is a significant public health problem. Though it is rare in most affluent countries there has been a slight resurgence recently in several European countries. The diagnosis of suspected cases and management of congenital syphilis may be confusing and the potential for severe disability is high when cases are missed. The cornerstone of congenital syphilis control is antenatal screening and treatment of mothers with penicillin and in affluent countries it should be strengthened among those at high risk. In developing countries antenatal care screening needs to be strengthened by implementing point-of-care decentralised screening and treatment, also alternative novel approaches to control congenital syphilis should be looked at and utilized. International health agencies and political parties should take steps urgently to support focused approaches to tackling the problem of continuing congenital syphilis.

Though many methods of prevention of STI/HIV are available, condoms remain of utmost importance. They have gone a long way from the oiled silk paper used by the Chinese and the hard sheaths made of tortoise- shell used by the Japanese to the latex condoms of today. The breakthrough came when the rubber vulcanization process was invented by Charles Goodyear and eventually the first rubber condom was made. The condom offers maximum protection( more than 90%) against HIV, Hepatitis B virus and N.Gonorrhoea. They also offer protection in scenarios when alternate sexual practices are adapted. The female condom in the only female driven contraceptive method available today. Graphene and Nano lubricated condoms are new in the market and others in futuristic approach may include wearable technology/Technology driven condom and invisible Condoms.Both Correct and Consistent use of condoms needs to be promoted for HIV/STI prevention.

Cost of treatment: The single biggest obstacle to HIV/AIDS treatment adherence in lower-middle class patients in Mumbai, India
Eknath Naik, Beata Casanas, Amar Pazare, Gauri Wabale, John Sinnott, Hamisu Salihu
January-June 2009, 30(1):23-27

PMID
:21938110
Background:
This study analyzes the social, economic and behavioral factors most frequently associated with adherence to Highly Active Antiretroviral Treatment (HAART) in urban India.
Materials and Methods:
Data was collected in a metropolitan teaching hospital in Mumbai using a cross-sectional survey design. Face-to-face interviews were conducted with 152 patients. The semistructured survey included both open and closed ended questions on socio-demographic, economic and behavioral factors. Factors affecting treatment adherence were analyzed.
Results:
The median age of patients was 40.5 years, 73% were males and all were heterosexual. Patients had been given ART from six months to five years (median is equal to 3.5). Ninety per cent lived at home and commuted to the clinic by bus or train. Behaviorally, 37% were sexually active, but only 55% used condoms. In assessing adherence, income, education, knowledge of their drugs, transportation, side effects, cost of treatment, distance from clinic and personal clinic satisfaction were analyzed. We found that 75% of patients reported cost of HAART to be the single greatest obstacle to adherence (p less than 0.01). Additionally, those claiming knowledge of their drugs were 2.3 times more likely to be adherent (p less than 0.03), while those who abused drugs or alcohol were 53% less likely to be adherent (p less than 0.03). There was no correlation with other factors.
Conclusions:
Our study population was representative of the lower middle class of India. It found that an educated, employed group considered the cost of treatment to be a significant obstacle for successful therapy. Additionally, it showed a significant increase in adherence when patients had knowledge of their HAART medications. Therefore, reducing the cost of medication as well as teaching about antiretroviral medications are both likely to improve adherence.

PMID
:23919052
Background:
Herpes genitalis is one of the commonest sexually transmitted infections in the world caused by herpes simplex virus (HSV) 1 and 2. All herpes viruses show latency. Herpes genitalis caused by HSV-1 and HSV-2 is recurrent in 55 and 90% of case respectively.
Aims:
To comparatively evaluate the therapeutic efficacy of topical zinc sulfate (ZnSO
4
) in varying concentrations in herpes genitalis.
Materials and Methods:
Ninety patients clinically diagnosed as herpes genitalis and confirmed by Tzanck test were taken up for study and divided into 3 groups of 30 patients each which were applied topical ZnSO
4
in concentrations of 1%, 2% and 4% respectively for 3 months. Ten patients of herpes genitalis were kept as control in whom only distilled water was applied. Patients were followed up for a total period of 6 months for any recurrences.
Results:
Ten patients of group 1 (1% ZnSO
4
) showed recurrence, 6 patients in group 2 (2% ZnSO
4
) and only one patient in group 3 (4% ZnSO
4
) showed recurrence. In the control group, 8 out of 10 patients showed recurrence. No serious side effects were seen in all 3 groups.
Conclusion:
Topical ZnSO
4
has been found to be an effective therapeutic modality not only for treatment but also for prolonging remissions in herpes genitalis. Topical 4% ZnSO
4
has been found to be most efficacious out of the three concentrations, without any side effects.

Zoon balanitis: A comprehensive review
Surabhi Dayal, Priyadarshini Sahu
July-December 2016, 37(2):129-138

The diagnosis and management of nonvenereal diseases are always a tough challenge for the dermatologist due to lack of studies on its diagnostic criteria and standard treatment guidelines. Zoon balanitis (ZB) is one of the benign nonvenereal dermatoses, which presents as a solitary, persistent erythematous plaque usually on the glans penis primarily in the uncircumcised, middle-aged to old-aged men. Although it was described by Zoon in 1952, its etiopathogenesis still remains hypothetical. This article provides an overview of the epidemiology, clinical presentation, histopathological features, and diagnostic criteria and diagnostic methods of ZB. In addition to this, it is rather very important to differentiate this lesion from its clinical equivocal lesions such as erythroplasia of Queyrat, infective and other inflammatory penile dermatoses, which has been discussed in this review. The treatment modalities have also been reviewed in details, and the importance of circumcision as the treatment of choice has been emphasized.

Genital lichen planus: An underrecognized entity
Ananta Khurana, Sidharth Tandon, Yogesh S Marfatia, Nina Madnani
July-December 2019, 40(2):105-112
DOI
:10.4103/ijstd.IJSTD_45_19
PMID

Genital lichen planus (LP) is an underrecogonized dermatosis. The appearance is often unlike classical LP elsewhere, and hence, the condition goes undiagnosed in many. Vulvo-vaginal LP in particular, can be a distressing condition often leading to scarring and a poor quality of life. Treatment for most of the genital LP variants is similar to managing LP elsewhere; however, the erosive variant requires special attention as treatment outcomes are often disappointing and the disease runs a protracted course. Potential for development of malignancy also exists, as in oral LP, and hence close follow up is essential.

Frequency of HBV, HCV and HIV infections among hospitalized injecting drug users in Kashan
M Sharif, Alireza Sherif, Mansour Sayyah
January-June 2009, 30(1):28-30
DOI
:10.4103/0253-7184.55477
PMID
:21938111
Context:
Infectious diseases including HIV and viral hepatitis constitute a major health issue, with high prevalence among injecting drug users (IDUs).
Aims:
The present study assessed the frequency of HIV, and hepatitis B and C viruses (HBV and HCV) among 200 IDUs, hospitalized between 2001 and 2006, in Shahid Beheshti Hospital of Kashan, Iran.
Setting and Design:
A population-based cross-sectional study in Iran.
Materials and Methods:
A total of 200 subjects participated in this study. Serological markers including HBsAg, anti-HCV antibodies and HIV were assessed by ELISA method using Monobid kits made in US. Demographic data was collected by using a questionnaire, which was designed by a researcher.
Statistical Analysis Used:
Frequencies were determined by employing SPSS:PC version 15.0, and Chi-square and Fisher's exact tests were used to compare proportions.
Results:
The mean age of subjects was 36.5 ± 10.2 years. Approximately 88.5% (177 cases) were male and 11.5%. (23 cases) were female. The frequency of positive infection test results for males with respect to HBV, HCV, and HIV was 4% (8 cases), 10.5% (21 cases), and 1.5% (3 cases); and for females it was 0.5% (1 case), 1.5% (3 cases), and 0% (0 case), respectively.
Conclusion:
This study demonstrates that the frequency of HBV, HCV, and HIV infection in the IVD user in Kashan, Iran, is relatively high and this condition is more serious in male than female drug addicts. It is very important, especially for health providers and policy makers, to recognize the risk factors of HBV, HCV and particularly HIV infection in this area and design effective preventive programs.

Characterization of patients with multiple sexually transmitted infections: A hospital-based survey
Shilpee Choudhry, VG Ramachandran, Shukla Das, SN Bhattacharya, Narendra Singh Mogha
July-December 2010, 31(2):87-91
DOI
:10.4103/0253-7184.74978
PMID
:21716792
Background:
Many studies have examined the inter-relationship between different STI. There are, however, a few data on patients presenting with more than one concurrent sexually transmitted infection (STI). The aim of the study was to determine the burden of patients with more than one concurrent STI and to characterize factors associated with such infections.
Materials and Methods:
Two hundred seventy five patients with one or more of the complaints, as enunciated by the World Health Organization (WHO) in its syndromic approach for the diagnosis of STI, were included as subjects. Detailed history, demographical data, and clinical features were recorded. All the patients were screened for common STIs. Multivariate analysis was performed taking all significant risk factor obtained from univariate analysis.
Results:
A total of 102 (37%) patients were identified as having multiple STIs amongst whom 72% (73/102) were male, 70% were married, and except one none reported regular use of condom The age of first sexual exposure was 13-17 years, 31.3% had more than three sexual partners in the past 6 months, and 76.4% had contact with commercial sex workers (CSWs). Multivariate analysis revealed statistical significance in relation to marital status, number of sexual partners exposed in the past 6 months, age of first sexual exposure, and age of patient at the time of presentation. Syphilis (48%) was the most common infection associated with multiple STI followed by HIV (45%) and HSV-2 (39.2%). None of the patients with multiple infections were detected and managed accurately by syndromic approach.
Conclusion:
Pattern of concurrent multiple STIs and the clinical severity of such multiple infections may serve as an indicator of the type of host-pathogen interaction determining the outcome of infection. When patient had multiple STIs, syndromic approach was not axiomatic and thus underscores the need for laboratory diagnosis.

Immunological failure despite virological suppression in HIV seropositive individuals on antiretroviral therapy
B Prabhakar, Asima Banu, HB Pavithra, P Chandrashekhara, Suresh Sasthri
July-December 2011, 32(2):94-98
DOI
:10.4103/0253-7184.85412
PMID
:22021970
Background:
Some individuals experience a discordant response during antiretroviral therapy (ART), with a blunted CD4+ cell count response despite low HIV-1 RNA plasma levels.
Materials and Methods:
CD4 counts and viral load of 251 individuals on ART referred to the center were analysed for immunological failure. The viral load tests of 28 patients revealed a discordant response, characterized by low CD4 counts despite viral suppression (<47 copies in 23, <5000 in 4 patients and <10000 in one patient). Univariate and multiple regression analysis was done to determine factors associated with immunological failure in patients with viral suppression.
Results:
Twenty-eight patients developed immunological failure over a duration of 3.7±1.14 years despite viral suppression. In univariate analysis of discordant patients, low CD4 counts(<100cells/μl) at start of ART(
P
=0.0261), less than 50% gain in CD4 count (
P
=0.048) after one year of start of ART and duration on ART for more than 3 years (
P
=0.0436) were associated with immunological failure. In multiple regression, duration on ART, age and nadir CD4 count (lowest ever) on treatment were predictors of immunological failure in these patients. Overall females (
n
=8) demonstrated much higher CD4 counts of 136±72 than males (
n
=20) 79±38 cells/μl at the time of diagnosis of immunological failure.
Conclusions:
Discordance was observed in 13.59% of patients. Detection of failure to first line therapy based on immunologic criteria, without viral load testing, can result in unnecessary switches to 2
nd
line therapy.
