    HIV-infected individuals have an increased risk of cardiovascular disease (CVD). T-allele carriers of the CD14 C-260T single-nucleotide polymorphism (SNP) have reported increased expression of the LPS-binding receptor, CD14 and inflammation in the general population. Our aim was to explore the relationship of this SNP with monocyte/macrophage activation and inflammation and its association with sub-clinical atherosclerosis in HIV-infected individuals.

    Lectins, carbohydrate-binding proteins, have been regarded as potential antiviral agents, as some can bind glycans on viral surface glycoproteins and inactivate their functions. However, clinical development of lectins has been stalled by the mitogenicity of many of these proteins, which is the ability to stimulate deleterious proliferation, especially of immune cells. We previously demonstrated that the mitogenic and antiviral activities of a lectin (banana lectin, BanLec) can be separated via a single amino acid mutation, histidine to threonine at position 84 (H84T), within the third Greek key. The resulting lectin, H84T BanLec, is virtually non-mitogenic but retains antiviral activity. Decreased mitogenicity was associated with disruption of pi-pi stacking between two aromatic amino acids. To examine whether we could provide further proof-of-principle of the ability to separate these two distinct lectin functions, we identified another lectin, Malaysian banana lectin (Malay BanLec), with similar structural features as BanLec, including pi-pi stacking, but with only 63% amino acid identity, and showed that it is both mitogenic and potently antiviral. We then engineered an F84T mutation expected to disrupt pi-pi stacking, analogous to H84T. As predicted, F84T Malay BanLec (F84T) was less mitogenic than wild type. However, F84T maintained strong antiviral activity and inhibited replication of HIV, Ebola, and other viruses. The F84T mutation disrupted pi-pi stacking without disrupting the overall lectin structure. These findings show that pi-pi stacking in the third Greek key is a conserved mitogenic motif in these two jacalin-related lectins BanLec and Malay BanLec, and further highlight the potential to rationally engineer antiviral lectins for therapeutic purposes.

    Talaromycosis typically occurs as an opportunistic infection among immunocompromised individuals. Infection caused by species other than T. marneffei is uncommon. While most reported cases describe infection in the lungs, we report an extremely rare intracranial Talaromyces species infection. This 61-year-old with end-stage renal disease who was unwell for the previous two months, presented with fever and worsening confusion lasting for three days. Lumbar puncture was suggestive of meningitis. Cerebrospinal fluid (CSF) culture was later confirmed to be Penicillium chrysogenum. The patient was co-infected with Group B Streptococcus sepsis. He improved with amphotericin B and ceftriaxone and was discharged with oral itraconazole for four weeks. However, he died of unknown causes two weeks later at home. Talaromyces species infection in the central nervous system is uncommon. This case highlighted a rare but life-threatening fungal meningitis. Among the four reported cases worldwide, none of the patients survived.

    Background: Antiretroviral therapy (ART) has transformed the management of human immunodeficiency virus (HIV) infection and significantly improved survival rates, but there is lack of such survival data from Malaysia.

    Objective: The objective was to determine the survival rates and prognostic factors of survival in HIV-infected adults treated with ART in Malaysia.

    Materials and Methods: This retrospective cohort study considered all HIV-positive adult patients registered in Sungai Buloh Hospital, a major referral center in Malaysia, between January 1, 2007 and December 31, 2016. Then, patients were selected through a systematic sampling method. Demographic, clinical, and treatment data were extracted from electronic medical records. Person-years at risk and incidence of mortality rate per 100 person-years were calculated. The Kaplan-Meier survival curve and log-rank test were used to compare the overall survival rates. Cox proportional hazards regression was applied to determine the prognostic factors for survival.

    Results: A total of 339 patients were included. The estimated overall survival rates were 93.8%, 90.4%, 84.9%, and 72.8% at 1, 3, 5, and 10 years, respectively, from ART initiation. The results of multiple Cox proportional hazard regression indicated that anemic patients were at a 3.76 times higher risk of mortality (95% confidence interval [CI]: 1.97-7.18; P < 0.001). The hazard risk was 2.09 times higher for HIV patients co-infected with tuberculosis (95% CI: 1.10, 3.96; P = 0.024).

    Conclusion: The overall survival rates among HIV-infected adults in this study are higher than that from low-income countries but lower than that from high-income countries. Low baseline hemoglobin levels of <11 g/dL and tuberculosis co-infection were strong prognostic factors for survival.

    Background: Death resulting from the acquired immunodeficiency syndrome (AIDS) is a worldwide concern. This study is aimed at determining the overall median survival time, and the prognostic factors of mortality among AIDS-infected patients in North-East Peninsular Malaysia.

    Methods: In 2018, a retrospective cohort study stretching from January to April was conducted. This study involved a review of data obtained from the National AIDS Registry. A total of 1,073 AIDS cases diagnosed from 1 January 2010 to 31 December 2014 were selected, and follow-up procedures were conducted until 31 March 2015 (a 3-month follow-up). The Kaplan-Meier plot and Cox's proportional hazard regression were used for data analyses.

    Results: 564 (52.5%) patients died due to AIDS, while the remaining 509 (47.4%) were censored. The overall median survival time was 11 months. The probability of survival in 1-year, 2-year, 3-year, 4-year and 5-year periods were 49.1%, 47.8%, 47.3%, 47.0% and 46.7%, respectively. Multiple Cox regression revealed that the significant prognostic factors were age 30-49 years [adjusted hazard ratio (Adj. HR) 1.57; 95% CI: 1.14, 2.16; P = 0.006], male (Adj. HR 1.39; 95% CI: 1.07, 1.79; P = 0.012), unemployed (Adj. HR 1.40; 95% CI: 1.12, 1.75; P = 0.003) and HIV-TB co-infection (Adj. HR 1.78; 95% CI: 1.37, 2.31; P < 0.001).

    Conclusion: The overall median survival time among AIDS patients in North-East Peninsular Malaysia was revealed to be short, in comparison to the other studies. The chances for survival can be improved with more emphasis on early detection (to ensure early treatment) and social support, particularly for HIV-TB co-infected patients, as well as for younger and unemployed patients.

    Heroin continues to be the main drug used in Malaysia, while amphetamine-type stimulants (ATS) have been recently identified as a growing problem. A cumulative total of 300,241 drug users were detected between 1988 and 2006. It is also estimated that Malaysia has 170,000 injecting drug users. HIV prevalence among drug users in the country ranges from 25% to 45%. Currently, there are approximately 380 general medical practice offices that offer agonist maintenance treatments for approximately 10,000 patients. There are 27,756 active patients in 333 general medical practice offices and government-run methadone maintenance treatment (MMT) centers. The Needle Syringe Exchange Program (NSEP) reached out to 34,244 injection drug users (IDUs) in 2011. In the last 2 years (2011 and 2012) the number of detected drug addicts decreased from 11,194 to 9015. The arrests made by the police related to opiate and cannabis use increased from 41,363 to 63,466 between the years 2008 and 2010, but decreased since 2010. An almost four-fold increase in the number of ATS and ketamine users was detected from 2006 (21,653 users) 2012 (76,812). Between 2004 and 2010, the yearly seizures for heroin ranged between 156 to 270 kg. However, in 2010 and 2011, heroin seizures showed a significant increase of 445kg and 410.02 kg, respectively. There has been a seizure of between 600 to 1000kg of syabu yearly from 2009 to 2012. Similar to heroin, increased seizures for Yaba have also been observed over the last 2 years. A significant increase has also been recorded for the seizures of ecstasy pills from 2011 (47,761 pills) to 2012 (634,573 pills). The cumulative number of reported HIV infections since 1986 is 94,841. In 2011, sexual activity superseded injection drug use as the main transmission factor for the epidemic. HIV in the country mainly involves males, as they constitute 90% of cumulative HIV cases and a majority of those individuals are IDUs. However, HIV infection trends are shifting from males to females. There are 37,306 people living with HIV (PLHIV) who are eligible for treatment, and 14,002 PLHIV were receiving antiretroviral treatment (ART) in 2011. The decreasing trend of heroin users who have been detected and arrested could be due to the introduction of medical treatments and harm reduction approaches for drug users, resulting in fewer drug users being arrested. However, we are unable to say with certainty why there has been an increase in heroin seizures in the country. There has been an increasing trend in both ATS users and seizures. A new trend of co-occurring opiate dependence and ATS underscores the need to develop and implement effective treatments for ATS, co-occurring opiate and ATS, and polysubstance abuse disorders. The low numbers of NSEP clients being tested for HIV underscores our caution in interpreting the decline of HIV infections among drug users and the importance of focusing on providing education, prevention, treatment, and outreach to those who are not in treatment.

    PURPOSE: Men who have sex with men and are sex workers (MSMSW) are disproportionately affected by the growing and emerging HIV epidemic. As sex work and same-sex behavior are heavily stigmatized and often illegal in most Asian countries, HIV research focusing on MSMSW has been limited. The goal of this analysis is to examine HIV testing practices and identify correlates of HIV testing among MSMSW in Asia.

    METHODS: The Asia Internet MSM Sex Survey, an online cross-sectional survey of 10,861 men who have sex with men (MSM), was conducted in 2010. Data on sociodemographic characteristics, HIV testing behaviors, and sexual behaviors were collected. Five hundred and seventy-four HIV-negative/unknown respondents reported receiving payment for sex with men at least once in the past 6 months and were included in this analysis. Multivariable logistic regression was conducted to identify independent correlates of HIV testing in the past year.

    RESULTS: About half (48.6%) of the participants had been tested for HIV at least once within the past year, and 30.5% had never been tested. We also found that MSMSW participants who engaged in risky behaviors were less likely to be tested.

    CONCLUSION: While one might expect a high HIV testing rate among MSMSW due to the risks associated with engaging in sex work, we found that HIV testing uptake is suboptimal among MSMSW in Asia. These results suggest that targeted HIV prevention and testing promotion among MSMSW are needed.

    Although vaccines have proven pivotal against arrays of infectious viral diseases, there are still no effective vaccines against many viruses. New structural insights into the viral envelope, protein conformation, and antigenic epitopes can guide the design of novel vaccines against challenging viruses such as human immunodeficiency virus (HIV), hepatitis C virus, enterovirus A71, and dengue virus. Recent studies demonstrated that applications of this structural information can solve some of the vaccine conundrums. This review focuses on recent advances in structure-based vaccine design, or structural vaccinology, for novel and innovative viral vaccine design.

    Globally, HIV/AIDS-related stigma and discriminatory attitudes deter the effectiveness of HIV prevention and care programs. This study investigated the general public's perceptions about HIV/AIDS-related stigma and discrimination towards people living with or affected by HIV/AIDS in order to understand the root of HIV/AIDS-related stigma and discriminatory attitudes. Study was carried out using qualitative focus group discussions (FGD). An interview guide with semi-structured questions was used. Participants were members of the public in Malaysia. Purposive sampling was adopted for recruitment of participants. A total 14 focus group discussions (n = 74) was carried out between March and July 2008. HIV/AIDS-related stigma and discrimination towards people living with HIV/AIDS (PLWHA) was profound. Key factors affecting discriminatory attitudes included high-risk taking behavior, individuals related to stigmatized identities, sources of HIV infection, stage of the disease, and relationship with an infected person. Other factors that influence attitudes toward PLWHA include ethnicity and urban-rural locality. Malay participants were less likely than other ethnic groups to perceive no stigmatization if their spouses were HIV positive. HIV/AIDS-related stigma and discrimination were stronger among participants in rural settings. The differences indicate attitudes toward PLWHA are influenced by cultural differences.

    Men who have sex with men (MSM) living in countries with strong stigma toward MSM are vulnerable to HIV and experience significant barriers to HIV care. Research is needed to inform interventions to reduce stigma toward MSM in these countries, particularly among healthcare providers. A cross-sectional survey of 1158 medical and dental students was conducted at seven Malaysian universities in 2012. Multivariate analyses of variance suggest that students who had interpersonal contact with MSM were less prejudiced toward and had lower intentions to discriminate against MSM. Path analyses with bootstrapping suggest stereotypes and fear mediate associations between contact with prejudice and discrimination. Intervention strategies to reduce MSM stigma among healthcare providers in Malaysia and other countries with strong stigma toward MSM may include facilitating opportunities for direct, in-person or indirect, media-based prosocial contact between medical and dental students with MSM.

    Introduction: Giant condyloma acuminata (GCA), also known as Bushke-Lowenstein tumour, is a rare disease which affects 0.1% of the population. Although histopathologically benign, it tends to be locally destructive. The common sites of involvement include the penis and the anorectum. Due to the rarity of the disease, there is a lack of controlled studies on the optimal management of this entity. Thus, we report a case of anogenital GCA in a 40-year-old HIV-positive man.

    Case presentation: A 40-year-old man presented with progressive anogenital warts associated with foul-smelling discharge and fever. He has been diagnosed with HIV and was on HAART on presentation. A warty excrescence had infiltrated the entire external genitalia, gluteals and sacral region. Serial excision was performed along with a defunctioning colostomy. The patient recovered well, and the final histopathological showed features of GCA.

    Discussion: With HIV, the HPV infection goes unchecked may develop into GCA. Malignant transformation to squamous cell carcinoma may occur in more than half of the cases. A complex interaction between HIV and HPV may lead to a higher risk of recurrence even after resection. The diagnosis is usually clinical. Imaging modalities may be used in identifying the extent and depth of invasion.

    Conclusion: The optimal management of anogenital giant condyloma acuminata remains to be determined. Staged surgical excision should be conducted to achieve an optimum outcome. Radical reconstructive surgery should be reserved for patients with recurrence, malignant transformation or sphincter involvement.

    We retrospectively reviewed 205 HIV-infected patients, who came at first entry from January 2001 to December 2002 to the Hospital Kuala Lumpur, Kuala Lumpur, Malaysia. The aged range was 21-69 years [mean 37.25 years (+/- SD) 8.1]. Subjects were mainly in the age group 35-44 years. The majority of patients were male (82%), Chinese (55.1%), single (55.6%), resided in Kuala Lumpur (55.1%), and were unemployed (57.1%). The most frequent routes of transmission were sexual contact (78.5%), followed by IDUs (30%), blood transfusion (5%), and unknown (0.5%). Oral candidiasis was the most common mucocutaneous disease and significant co-existence was found with the main opportunistic systemic diseases, such as TB, PCP, toxoplasmic encephalitis, penicillosis, and CMV retinitis (p < 0.05). In this study, the range of CD4 counts was 0-910, with a median of 35 cells/mm3. Significant associations between a CD4 level less than 100 cells/mm3 at the time of diagnosis, and the occurrence of major opportunistic diseases, such as candidiasis, TB, PCP, TE, herpes simplex infection, CMV retinitis, penicillosis, and histoplasmosis were found (p < 0.05) in this study.

    The objective of the study was to determine the proportion of sound HIV knowledge and common misconceptions about HIV among university students. A set of pre tested and validated questionnaire assessing sound HIV knowledge and common misconceptions about HIV was used in this cross sectional study. HIV knowledge was defined as sound when one was able to identify correctly two ways of preventing the sexual transmission of HIV and reject three major misconceptions about HIV. Out of 300 respondents, 298 completed the questionnaire giving a response rate of 99.3%. A total of 40.9% of university students have sound HIV knowledge. The majority of those who lacked sound HIV knowledge were young (60.2%) and female (60.4%). A significant proportion still believed that HIV can be transmitted via social contact (13.8%), by sneezing or coughing (11.4%) and mosquito bites (10.1%). About 6.7% were believed wrongly that HIV can be treated by vaccine and healthy-looking people cannot have HIV.

    The HIV positive cases in Malaysia and the world are increasing from day to day among individuals of all races and ages. However, the issue of social support for HIV positive patients still needs to be discussed in detail as this issue will have an impact on the lives of HIV positive patients in Malaysia. The focus of this study is to examine social support among HIV positive people in Malaysia. This study used a full qualitative method to collect and analyze data. Five male informants with HIV positive were involved in this study. All informants were interviewed separately using semi structured interview methods. Among the topics discussed in this study were family acceptance, the type of social support they received and the social support resources. The findings showed that, four out of five informants were infected with the HIV viruses from sharing needle and one informant was infected from unprotected sex. The results showed that they received adequate social support in terms of emotions, information, instrumental and networking from various sources. Nevertheless, social support for HIV positive people in Malaysia still needs to be discussed and promoted to ensure their psychological well-being.

    Medication adherence remains a critical link between the prescribed ART regimen and treatment outcome. Several factors may influence adherence behavior. This cross-sectional study aimed to highlight socioeconomic predictors of adherence behavior among a cohort of 242 adult Malaysian patients receiving antiretroviral therapy in Hospital Sungai Buloh, Malaysia, where they were enrolled in a parent study (single-blinded randomized controlled trial) between January and December 2014. Statistical analysis of secondary data on adherence behavior and sociodemographic characteristics of the patients revealed mean age of 33.4 years and ranged from 18 to 64 years; 88.8% were males. A total of 224 (93%) patients who completed 6 months' adherence assessment were included in the model. Of these, 135 (60.3%) achieved optimal adherence. Multivariate binary logistic regression analysis revealed that patient's income and ethnicity were significant predictors of adherence behavior. This may be valuable for targeted programmatic interventions to further enhance successful treatment outcomes among the target population.
