Prevalence of latent tuberculosis infection and HIV among people who inject drugs in Iran.

INTRODUCTION: Iran has an human immunodeficiency viruses (HIV) epidemic that is concentrated among people who inject drugs (PWID), who have higher risks of progression from latent tuberculosis infection (LTBI) to active disease. The aim of this study is to measure prevalence of LTBI, HIV infection and any risk behaviors among PWID in Iran. METHODS: The cross-sectional study was conducted from August to December 2013 in six cities across Iran. A total of 420 PWID were recruited from drop-in centres using convenience sampling. Trained interviewers collected data on socio-demographic characteristics, drug use history and drug-related risk behaviors across the study sites. A tuberculin skin test (TST) was performed, and HIV infection was assessed by a rapid test. Multivariable modified Poisson regression and logistic regression were used for data analysis. RESULTS: Prevalence of positive TST and HIV positivity was 35.7% and 8.6%, respectively. The prevalence of LTBI and HIV was significantly different across the cities of this study. Positive TST was independently associated with older age (APR 1.03, 95% CI 1.01, 1.05) and being HIV positive (APR 1.89, 95% CI 1.45, 2.47). HIV infection was associated with lifetime history of sharing syringes (AOR 3.28, 95% CI 1.44, 10.71) and lifetime number of imprisonment (AOR 1.09, 95% CI 1.03-1.14). DISCUSSION AND CONCLUSIONS: Prevalence of LTBI infections among PWID is high and independently associated with HIV infection. Given that there are currently no TB services available within drop-in centres, programs which integrate TB case finding, TB preventive therapy, referral and care services for PWID are urgently needed.

Six-month follow-up of Iranian women in methadone treatment: drug use, social functioning, crime, and HIV and HCV seroincidence.

BACKGROUND: In general, information about women who use drugs comes from studies performed in the West. Whether women in countries such as Iran are likely to enter drug treatment or how they will respond is not known. PURPOSE: To examine the short-term impact of methadone maintenance treatment (MMT) on drug use, dependence, social functioning, crime, and human immunodeficiency virus (HIV) and hepatitis C virus (HCV) risk behavior and seroincidence in female drug users in Iran. METHODS: Women were eligible for inclusion in the study if they were assessed as dependent on opiates according to the International Statistical Classification of Diseases and Related Health Problems, tenth revision (ICD-10). The sample comprised 78 female heroin or opium users who attended the Persepolis women's drug treatment clinic in Tehran between 2007 and 2008. Participants were followed up in 2009/2010. Heroin and the use of other drugs, social functioning, involvement in crime, and involvement in HIV and HCV risk behavior were measured by self-report. The prevalence and incidence of HIV and HCV were measured by serology and self-report. FINDINGS: Of the 78 women recruited, 40 were followed up, and this occurred approximately 7 months later. One in four women reported a history of drug injection. At follow-up there were significant reductions in self-reported heroin use on ICD-10 dependence scores. Subjects with more severe drug dependence at baseline were significantly more likely to be criminally active than less severely dependent subjects. Baseline prevalence for HIV and HCV was 5% and 24%, respectively. At follow-up, no one had acquired HIV infection, but one participant had acquired HCV, giving an incidence rate of 7.1 per 100 person-years. CONCLUSION: This research provides the first evidence that Iranian female drug users can enter MMT and respond well. Within a few months of entering MMT, improvements occurred in heroin use, levels of dependence, social functioning, and HIV risk behavior. While the incidence of blood-borne viral infections was low, there was a serious risk of HIV transmission among this cohort and also to participants' needle and sexual contacts. In a country with high levels of drug use, the high levels of HCV among female drug users require more women to enter drug treatment if an HIV epidemic is to be avoided. Many participants had a chronic drug problem and had had little or no previous exposure to MMT. The introduction or expansion of women-only drug treatment services is urgently needed in order to engage more women in treatment.

Characteristics of Iranian women seeking drug treatment.

BACKGROUND: In the west, men are twice as likely as women to develop a drug problem, but female users have higher rates of morbidity than male users. Iran has the world highest per capita opiate consumption, but little is known about female drug users. In 2007, we established a free methadone clinic with ancillary services for female drug users in South Tehran. The aim was to explore the characteristics of female drug users seeking treatment for heroin dependence in Iran. Clients were interviewed about demographic characteristics, drug use and treatment history, and drug-related health problems. Urine and blood samples were collected and tested for morphine, HIV, hepatitis C virus (HCV), and sexually transmitted infections (STIs). METHODS: Between August 2007 and October 2008, 78 women completed a baseline interview. The median age was 37 years, the main ethnic background was Persian (65%), and half of the clients were married. Opium and heroin and opium use was reported by 69% (n=54) and 87% (n=68) of clients, respectively. The mean duration of heroin use problems was 10.5 years, and only 20% of women reported ever having received drug treatment. HIV and HCV seroprevalence was 5% and 24%, respectively. Forty percent were sexually active when interviewed, and one third tested positive for an STI. Women had poor social functioning, high levels of depression, and poor general health. RESULTS AND CONCLUSIONS: Our clients were dependent users with a multitude of problems who had little or no contact with treatment agencies before this study. Many clients had made a transition from using opium to using heroin, and some had commenced injecting, placing them at risk for HIV and HCV infection. More women-only drug treatment services are needed to facilitate women's entry into drug treatment.

Correlation between Lower Urinary Tract Scoring System, Behavior Check List, and Bladder Sonography in Children with Lower Urinary Tract Symptoms.

PURPOSE: The Pediatric Lower Urinary Tract Scoring System (PLUTSS) is a standardized questionnaire used for screening and evaluation of the response of children with lower urinary tract symptoms (LUTS) to therapy. We presumed that adding the Child Behavior Check List (CBCL) and bladder volume wall index (BVWI) to the PLUTSS would increase its validity in the detection of children with LUTS. MATERIALS AND METHODS: One hundred twenty-two children aged 5 to 15 years with LUTS were enrolled in the study. Seventy-two healthy, age-matched children without urinary complaints were considered as controls. The PLUTSS and CBCL were filled out for all children. Sonography was performed to measure BVWI. Chi-square test and likelihood ratio were used to compare frequencies, receiver operating curve (ROC) analysis was used to evaluate the correlation, and Cohen's kappa was used to measure the agreement between variables. p-values <0.05 were considered significant. RESULTS: Behavior problems were significantly more common in children with LUTS than in healthy children (p<0.05). The frequency of thick, thin, and normal BVWIs did not differ significantly in the two groups (p>0.05). ROC analysis showed that there was no correlation between PLUTSS, CBCL, and BVWI in either the LUTS subgroup or in the controls (p>0.05). The PLUTSS had the highest sensitivity and specificity, and adding the two other tests decreased its validity for the diagnosis of children with LUTS. CONCLUSIONS: The PLUTSS by itself was the best predictor of LUTS. The CBCL and BVWI were not helpful in making a diagnosis; however, the CBCL was useful in the detection of behavior problems in children with non-monosymptomatic enuresis.

The establishment of a methadone treatment clinic for women in Tehran, Iran.

In Iran women are less likely than men to use drugs, but suffer greater morbidity, are stigmatised, and are less likely to seek treatment. In 2007, we established a clinic in Tehran for drug using women. We report here on our study of the 97 women who registered in the first year of operation. We profiled these women: demographics, drug use, risk behaviour, and use of services. The clinic's services were heavily used. We interviewed clients and staff about the clinic and learned that intensive help is needed for women trying to recover from years of drug use. We conclude that female drug users will make use of harm reduction services if they are provided in a setting designed and operated for women.
