    BACKGROUND: Mycobacterium avium complex prophylaxis is recommended for patients with advanced HIV infection. With the decrease in incidence of disseminated Mycobacterium avium complex infection and the availability of antiretroviral therapy (ART), the benefits of macrolide prophylaxis were investigated. This study examined the impact of macrolide prophylaxis on AIDS-defining conditions and HIV-associated mortality in a cohort of HIV-infected patients on ART.

    METHODS: Patients from TREAT Asia HIV Observational Database (September 2015 data transfer) aged 18 years and older with a CD4 count <50 cells/mm at ART initiation were included. The effect of macrolide prophylaxis on HIV-associated mortality or AIDS-defining conditions (as a combined outcome) and HIV-associated mortality alone were evaluated using competing risk regression. Sensitivity analysis was conducted in patients with a CD4 <100 cells/mm at ART initiation.

    RESULTS: Of 1345 eligible patients, 10.6% received macrolide prophylaxis. The rate of the combined outcome was 7.35 [95% confidence interval (CI): 6.04 to 8.95] per 100 patient-years, whereas the rate of HIV-associated mortality was 3.14 (95% CI: 2.35 to 4.19) per 100 patient-years. Macrolide use was associated with a significantly decreased risk of HIV-associated mortality (hazard ratio 0.10, 95% CI: 0.01 to 0.80, P = 0.031) but not with the combined outcome (hazard ratio 0.86, 95% CI: 0.32 to 2.229, P = 0.764). Sensitivity analyses showed consistent results among patients with a CD4 <100 cells/mm at ART initiation.

    CONCLUSIONS: Macrolide prophylaxis is associated with improved survival among Asian HIV-infected patients with low CD4 cell counts and on ART. This study suggests the increased usage and coverage of macrolide prophylaxis among people living with HIV in Asia.

    BACKGROUND: In resource-limited settings, HIV-related services are often targeted to younger key populations, although increasing reports have found that adults ≥50 years now account for among the highest increase in new HIV diagnosis. We assessed the proportion of new HIV infections among older adults (≥50 years) and compared their sociodemographics, risk behaviors, and HIV-related outcomes to newly diagnosed younger adults (<50 years).

    METHODS: This retrospective analysis included all new HIV diagnosis from 2016 to 2019 at the University of Malaya Medical Centre, Malaysia. Trends of HIV diagnosis was assessed using join point regression analysis, and characteristics between the older and younger adults were compared using χ 2 test or Mann-Whitney U test. Kaplan-Meier analysis and log-rank test were used to compare the survival probability in both age groups.

    RESULTS: From a total of 594 new HIV diagnosis between 2016 and 2019, 11.5% (N = 68) were among older adults with an annual percent increase of 5.50%. Older adults were more likely ethnic Indians ( P < 0.001), acquired HIV through heterosexual contact ( P = 0.001), had late presentation to care ( P = 0.003), and multimorbidity ( P < 0.001). Immunological responses after 12 months on antiretroviral therapy were comparable in both the groups. Older adults had a higher probability of death compared with younger adults (adjusted hazard ratio 1.81, 95% confidence interval: 1.02 to 3.23, P = 0.043) after adjusting for sex, mode of HIV transmission, late presentation to care, antiretroviral therapy initiation, and multimorbidity.

    CONCLUSION: Older adults diagnosed with HIV were associated with late care presentation and increased mortality. There is an urgent need to enhance uptake of HIV testing and linkage to care among older individuals in our setting.

    BACKGROUND: Linkage studies have reported high rates of previously unascertained mortality among people living with HIV (PLHIV) who have been lost to follow-up (LTFU). We assessed survival outcomes among PLHIV who were LTFU in Thailand and Malaysia, through linkages to a national death registry or HIV database.

    METHODS: Data linkages with the national death registry or national HIV database were conducted in 2020 on all PLHIV who met LTFU criteria while enrolled in care at participating HIV clinical sites. LTFU was defined as having no documented clinical contact in the previous year, excluding transfers and deaths. Survival time was analyzed using the Cox regression, stratified by site.

    RESULTS: Data linkages were performed for 489 PLHIV who had been LTFU at sites in Malaysia (n = 2) and Thailand (n = 4). There were 151 (31%) deaths after being LTFU; the mortality rate was 4.89 per 100 person-years. Risk factors for mortality after being LTFU were older age [41-50 years: hazard ratio (HR) = 1.99, 95% confidence interval (CI): 1.08 to 3.68; and older than 50 years: HR = 4.93, 95% CI: 2.63 to 9.22; vs. age 30 years or younger]; receiving NRTI + PI (HR = 1.87, 95% CI: 1.22 to 2.85 vs. NRTI + NNRTI); positive hepatitis C antibody (HR = 2.25, 95% CI: 1.40 to 3.62); and having previous AIDS illness (HR = 1.45, 95% CI: 1.03 to 2.05). An improved survival was seen with a higher CD4 count (CD4 351-500 cells/µL: HR = 0.40, 95%CI: 0.21-0.76; and CD4 >500 cells/µL: HR = 0.43, 95%CI: 0.25-0.75; vs. CD4 ≤200 cells/µL).

    CONCLUSIONS: Almost one-third of PLHIV who were LTFU in this cohort had died while out of care, emphasizing the importance of efforts to reengage PLHIV after they have been LTFU and ensure they have access to ongoing ART.

    BACKGROUND: Tuberculosis (TB) is a common infection in people living with HIV. However, the risk factors for HIV/TB co-infection in second-line HIV therapy are poorly understood. We aimed to determine the incidence and risk factors for TB co-infection in SECOND-LINE, an international randomized clinical trial of second-line HIV therapy.

    METHODS: We did a cohort analysis of TB cases in SECOND-LINE. TB cases included any clinical or laboratory-confirmed diagnoses and/or commencement of treatment for TB after randomization. Baseline factors associated with TB were analyzed using Cox regression stratified by site.

    RESULTS: TB cases occurred at sites in Argentina, India, Malaysia, Nigeria, South Africa, and Thailand, in a cohort of 355 of the 541 SECOND-LINE participants. Overall, 20 cases of TB occurred, an incidence rate of 3.4 per 100 person-years (95% CI: 2.1 to 5.1). Increased TB risk was associated with a low CD4+-cell count (≤200 cells/μL), high viral load (>200 copies/mL), low platelet count (<150 ×109/L), and low total serum cholesterol (≤4.5 mmol/L) at baseline. An increased risk of death was associated with TB, adjusted for CD4, platelets, and cholesterol. A low CD4+-cell count was significantly associated with incident TB, mortality, other AIDS diagnoses, and virologic failure.

    DISCUSSION: The risk of TB remains elevated in PLHIV in the setting of second-line HIV therapy in TB endemic regions. TB was associated with a greater risk of death. Finding that low CD4+ T-cell count was significantly associated with poor outcomes in this population supports the value of CD4+ monitoring in HIV clinical management.

    OBJECTIVE: To assess recent trends in the monitoring of antiretroviral therapy (ART) and detection of ART failure in adult and pediatric HIV clinics.

    METHODS: We used data collected from 21 adult and 17 pediatric sites (across 13 and 6 countries/territories, respectively) in the International Epidemiology Databases to Evaluate AIDS - Asia-Pacific cohort. ART failure was defined as viral, immune, or clinical consistent with WHO guidelines.

    RESULTS: A total of 8567 adults and 6149 children contributed data. Frequency of CD4 count monitoring declined between 2010 and 2019 among adult sites (from 1.93 to 1.06 tests/person per year, a 45.1% decline) and pediatric sites (from 2.16 to 0.86 testsperson per year, a 60.2% decline), whereas rates of viral load monitoring remained relatively stable. The proportion of adult and pediatric treatment failure detected as immune failure declined (from 73.4% to 50.0% and from 45.8% to 23.1%, respectively), whereas the proportion of failure detected as viral failure increased (from 7.8% to 25.0% and from 45.8% to 76.9%, respectively). The proportion of ART failure detected as clinical failure remained stable among adult and pediatric sites. The largest shifts in ART monitoring and failure type occurred in lower middle-income countries.

    CONCLUSIONS: Although viral failure in our Asian cohort now comprises a larger portion of ART failure than in prior years, the diagnostic characteristics of immune and clinical failure, and recommendations on their management, remain important inclusions for regional ART guidelines.

    BACKGROUND: Roughly 4% of the 1.25 million patients on antiretroviral therapy (ART) in Asia are using second-line therapy. To maximize patient benefit and regional resources, it is important to optimize the timing of second-line ART initiation and use the most effective compounds available.

    METHODS: HIV-positive patients enrolled in the TREAT Asia HIV Observational Database who had used second-line ART for ≥6 months were included. ART use and rates and predictors of second-line treatment failure were evaluated.

    RESULTS: There were 302 eligible patients. Most were male (76.5%) and exposed to HIV via heterosexual contact (71.5%). Median age at second-line initiation was 39.2 years, median CD4 cell count was 146 cells per cubic millimeter, and median HIV viral load was 16,224 copies per milliliter. Patients started second-line ART before 2007 (n = 105), 2007-2010 (n = 147) and after 2010 (n = 50). Ritonavir-boosted lopinavir and atazanavir accounted for the majority of protease inhibitor use after 2006. Median follow-up time on second-line therapy was 2.3 years. The rates of treatment failure and mortality per 100 patient/years were 8.8 (95% confidence interval: 7.1 to 10.9) and 1.1 (95% confidence interval: 0.6 to 1.9), respectively. Older age, high baseline viral load, and use of a protease inhibitor other than lopinavir or atazanavir were associated with a significantly shorter time to second-line failure.

    CONCLUSIONS: Increased access to viral load monitoring to facilitate early detection of first-line ART failure and subsequent treatment switch is important for maximizing the durability of second-line therapy in Asia. Although second-line ART is highly effective in the region, the reported rate of failure emphasizes the need for third-line ART in a small portion of patients.

    Introduction: Hormonal abnormality is one of many clinical manifestations of HIV infections
    that is not well understood. However, the consequences could affect quality of life and are
    potentially treatable. Thus, this study aimed to determine the prevalence and associated
    factors of thyroid, adrenal and gonadal dysfunctions among HIV-infected patients. Methods:
    This is a single centre cross-sectional study involving 150 HIV-infected patients attending the
    HIV clinic. Each subject was required to answer specific symptoms questionnaire and their
    medical records were reviewed for relevant clinical and biochemical data. Blood for was
    collected and thyroid hormones, cortisol, ACTH, FSH, LH, testosterone and estradiol were
    analysed using electrochemiluminescent immunoassay. Thyroid, adrenal and gonadal axes
    abnormalities were identified. Results: Hypogonadism had the highest prevalence amongst
    the endocrine abnormalities, which was detected in 23 patients (15.3%), followed by thyroid
    dysfunction in 18 patients (12%) and hypocortisolism in 2 patients (1.3%). There was
    significant correlation between CD4 count, BMI and age with the hormone levels. Conclusion:
    Prevalence of endocrine abnormalities was low in these well-treated HIV-positive patients,
    with hypogonadism being the most common. However, significant correlations between CD4
    count, age and BMI with the hormonal levels were detected. Clinical symptoms in relation to
    endocrinopathy are not specific as a screening tool thus underscoring the need for
    biochemical tests to identify these treatable conditions.

    Initiation of Highly Active Anti-Retroviral Therapy (HAART) depends on clinical or immunological criteria. Clinical criteria include the presence of opportunistic infections, categorized by the WHO as stage 3 and 4. Immunological criteria are based on CD4 cell count. The WHO guidelines have changed frequently. All patients with CD4 cell count less than 200 cells/µl and symptomatic HIV or late disease or severe recurrent HIV illnesses or patients with AIDS or tumor at any CD4 count, should start therapy. WHO guidelines in 2013 recommended initiating HAART at CD4 counts less than 500 cells/µl. HAART is usually initiated when CD4 is less than 200 cell/µl because HIV infected patients present at a late stage. Research on factors responsible for this is sorely needed so that interventions can be targeted at this group.

    BACKGROUND: Mucocutaneous lesions directly related to human immunodeficiency virus (HIV) infection usually present as initial manifestations of immune deficiency. The most common mucocutaneous lesions are Kaposi's sarcoma, histoplasmosis, oro-esophageal candidiasis, oral hairy leukoplakia, and, in Asia, Penicillium marneffei infection. Non-HIV-related skin lesions, such as psoriasis, seborrheic dermatitis, and nodular prurigo, may be the initial presentation among HIV infected patients attending outpatient clinics.

    METHODS: A retrospective analysis was performed on 145 HIV-positive Malaysians of Chinese descent from two centers at the University Hospital Kuala Lumpur (UHKL) and the General Hospital Kuala Lumpur (GHKL) from March 1997 to February 1998. Demographic data and clinical data were analyzed.

    RESULTS: The analysis showed that 104 out of 145 patients had mucocutaneous disorders (71.7%). In the study, there were 100 men (96.2%) and four women (3.8%). The majority of patients were in the age group 20-50 years. The patients who presented with mucocutaneous disease also had low CD4+ T-lymphocyte counts and most had acquired immunodeficiency syndrome (AIDS) defining illness. The number of cases with generalized hyperpigmentation was very high in the group (35.9%), followed by nodular prurigo (29.7%) and xerosis (27.6%). Seborrheic dermatitis was seen in 20.7% of cases, with psoriasis in 8.3%. The most common infections were oral candidiasis (35.9%), tinea corporis and onychomycosis (9.7%), and herpes infection (5.5%); however, mucocutaneous manifestations of Kaposi's sarcoma were rare.

    CONCLUSIONS: The results suggest that mucocutaneous findings are useful clinical predictors of HIV infection or signs of the presence of advanced HIV infection.

    A retrospective study of 144 adults with HIV infection was conducted to investigate the prevalence of upper and lower respiratory tract infections (URTIs and LRTIs). The patients were divided into two groups: those with acquired HIV through intravenous drug abuse (IVDA), and those who had acquired HIV through 'other' risk behaviours. LRTIs were more prevalent than URTIs overall, and LRTIs were significantly more common (p < 0.001) in IVDAs than in the other-risk group. Tuberculosis (40%) and bacterial pneumonias (33%) comprised the majority of LRTIs among IVDAs, while Pneumocystis carinii pneumonia (40%) was the commonest LRTI in the other-risk group. Analysis of CD4 T-lymphocyte counts indicated that HIV-seropositive IVDAs are at greater risk of developing chest infections at higher CD4 counts than other-risk patients. The IVDAs were also found to have a much higher rate of co-infection with hepatitis C and B, which may be a factor accelerating the progression from HIV infection to AIDS. The mean time averaged for the two groups from known seroconversion to development of respiratory tract infection is only 1.37 years, which suggests HIV-infected patients are presenting late for treatment in Malaysia.

    To explore the heterogeneity of CD4 responses following highly active antiretroviral therapy, the patterns of CD4 recovery of HIV-1-infected Chinese patients who have been on their first antiretroviral regimen for ≥5 years were analysed. The CD4 trajectories were traced, smoothed and differentiated into three defined profiles. Half (56.3%) were 'satisfactory responders', with CD4 gain of >100 cells/μL and a peak of >350 cells/μL, plateauing before the end of Year 5. Thirty-three (24.4%) were 'continuing responders' whose CD4 rise persisted at Year 4-5. The remaining 26 (19.3%) were 'poor responders'. Presentation with AIDS before therapy was common not just among 'poor' but also paradoxically the 'continuing' responders. While a majority had responded well to antiretroviral therapy, older patients and those with AIDS diagnosis before initiation of therapy may never achieve a satisfactory level even with effective treatment. Categorization of HIV patients by their CD4 trajectory may support the prediction of immunological outcome over time, and ultimately inform treatment choices.

    A cross-sectional study was undertaken to determine the clinical profile, haematological and biochemical changes, seroprevalence of common opportunistic pathogens, and AIDS-defining events in 49 Malaysian male drug addicts with HIV infection. Their mean age was 33.2 years, the majority had been injecting drugs for more than 5 years and 88% reporting sharing needles. Fatigue, weight loss and night sweats were common presenting symptoms and the most frequent physical findings were hepatomegaly (57%), lymphadenopathy (35%) and thrush (29%). Pulmonary infections were the commonest complications seen (61%) and of these, 13 had septic pulmonary emboli, 7 had bacterial pneumonias, 7 had pulmonary tuberculosis, and 4 had Pneumocystis carinii pneumonia. Eight patients had infective endocarditis and 5 had infected pseudoaneurysm in the groin. Anaemia (82%), leucocytosis (53%), hypoalbuminaemia (43%), hyperglobulinaemia (88%), elevated liver enzymes and hyponatraemia (57%) were frequent laboratory findings. The prevalence of HCV, HBV, cytomegalovirus and toxoplasma infection (by serology) were 100%, 12.2%, 72.7% and 59% respectively. All 7 patients with AIDS (4 P. carinii pneumonia, 2 extrapulmonary tuberculosis, and one oesophageal candidiasis) presented with their AIDS-defining illness, suggesting that HIV-infected intravenous drug user (IVDU) patients present late in the course of the disease.

    The incidence of tuberculosis (TB) is currently increasing. HIV induced immuno-suppression modifies the clinical presentation of TB. Our aim is to determine the differences in clinical presentation of HIV-TB co-infection based on their CD4 counts. This retrospective study looked at cases of adult active TB and HIV-1 co-infection treated in Penang Hospital from January 2004 to December 2005. Of the 820 patients treated for active TB, HIV-1 seropositivity rate was 12.6% (103 patients). Majority of HIV-1 co-infected patients presented with prolonged insidious and non-specific symptoms like weight loss, fever and night sweats. The clinical presentation of TB depended on the stage of HIV-1 infection and associated degree of immunodeficiency. Compared to the less immuno-compromised HIV-1 and TB co-infected population (CD4 > 200/mm3 ), patients with CD4 counts ≤ 200 are more likely to have atypical chest radiographs (P = 0.009). During active TB, the Mantoux test was positive in 12 (14.5%) HIV-1 infected patients with a CD4 counts ≤ 200/mm3 and in 16 (80%) of those with CD4 counts > 200/mm3 (P = 0.0001). In our series, the AFB smear / AFB culture and type of TB did not show obvious correlation with CD4 counts. Therefore to diagnose TB in severely immuno-compromised HIV patients, we need to have a high index of suspicion.

    The most frequent ocular manifestation of acquired immunodeficiency syndrome (AIDS) is cytomegalovirus retinitis (CMVR). This infection is reportedly inversely proportional to the CD4 counts. Usually CMVR develops once the CD4 counts fall below 50/mm3. Our case report documents an AIDS patient who developed CMVR despite CD4 counts being persistently >200/mm3. The patient was self-administering dehydroepiandrosterone, high dose Vitamin C, testosterone and hydrocortisone. This case report describes a unique case of pharmacologically induced elevated CD4 counts, which however, did not prevent the development of CMVR in the patient.

    CONTEXT: Diarrhoea is one of the major complications occurring in over 90% of HIV-infected individuals in developing countries. Coccidian group of parasites, being opportunistic pathogens, have been implicated as the most common causative agents of diarrhoea among HIV-infected population.

    AIMS: The aim was to study the magnitude of parasitic diarrhoea with special context to coccidian parasitic infections in HIV-infected individuals and their association with the patient's immunological status measured by CD4 T-cell counts.

    SETTINGS AND DESIGN: This investigation was performed between January 2002 and December 2014 at a tertiary HIV care centre in Chennai, South India.

    MATERIALS AND METHODS: Stool samples were collected and microscopically observed for parasites using direct, formal-ether-concentrated wet mounts and modified acid-fast staining for coccidian parasites. CD4 T-cell counts were done by FACScount.

    STATISTICAL ANALYSIS USED: All statistical analyses were performed using GraphPad Prism software, version 5.0, andP < 0.05 was considered statistically significant.

    RESULTS: Coccidian parasitic infection accounted for about 23.4% of parasitic infections, and of these, Cystoisospora belli was observed to be the most common cause of diarrhoea (88.8%), followed by Cryptosporidium spp. (9.9%) and Cyclospora spp. (1.3%). Trend analysis of coccidian aetiology during the study period revealed a significant rise in the positivity of C. belli and Cryptosporidium spp. (P = 0.001). Among the HIV patients with CD4+ T-cell counts <200 cells/μL, Cryptosporidium infection was most common (90%), followed by infection with C. belli(61.4%).

    CONCLUSIONS: Coccidian parasites continue to be the most common aetiological agent of diarrhoea among patients with HIV. The increasing trend of positivity of both cystoisosporiasis and cryptosporidiosis over the study period and the high positivity of cryptosporidiosis in patients with lower CD4+ T-cell counts are issues of serious concern. The findings call for the need for the early diagnosis of coccidian parasites and appropriate intervention among HIV-infected patients.

    Immune reconstitution inflammatory syndrome (IRIS) continues to be a complication in HIV/tuberculosis (TB) co-infected patients initiating highly active antiretroviral therapy (HAART). The aim of this study was to evaluate the risk factors associated with developing IRIS to identify a possible biomarker to predict or diagnose IRIS in patients initiating HAART. A total of 175 HIV/TB co-infected patients initiating HAART were followed up longitudinally during September 2010 to May 2013 attending a HIV care clinic in Chennai. Patients were followed up longitudinally after HAART initiation and baseline demographic, laboratory parameters and treatment characteristics between patients with IRIS events and those without IRIS events were compared. Chi-square or Fisher's exact test for categorical variables and a Wilcoxon rank-sum test for continuous variables were performed using SPSS, version 12.0 software. Patients with IRIS had a significantly lower median baseline CD4+ T-cell count (P = 0.0039). There were no differences in terms of sex, CD4 T-cell %, plasma viral load, time interval between initiating ATT and HAART between the IRIS and non-IRIS patients. Low CD4+ T-cell count (<100 cells/μL) could be used as a marker to screen and monitor patients initiating HAART.

    The CD4+ T-lymphocyte absolute count (CD4ac), CD4+ T-lymphocyte percentage (CD4%) and total lymphocyte count (Løac) were assessed in HIV-seropositive intravenous drug users (IVDU) with reference to their correlation with the clinical categories A, B, and C as stipulated by the Centre of Disease Control and Prevention, USA (CDC) and with each other. It was found that while the CD4ac and Løac correlated with the clinical categories, CD4% did not. This may suggest that in our local setting, the CD4% may not necessarily be a suitable alternative marker to CD4ac as proposed by CDC. Furthermore, the CD4% of the normal subjects in this study was found to be relatively lower than the reported Caucasian levels. This may indicate that the use of the cut-off level of less than 14% as an AIDS-defining criteria may not be applicable for our HIV-seropositive IVDU. In addition, unlike the CD4ac which correlated directly with CD4% and Løac, the CD4% did not correlate with Løac. Therefore, due to the observed disparity with clinical status of patients and its possibly lower levels in our normal population, CD4% as a marker for staging HIV disease should be used with caution in our setting. Such findings may also have an impact on the use of established markers for the monitoring and classification of HIV-infected individuals in this region.

    The lymphocyte subset expressing the gamma delta T cell receptor is increased in several infectious diseases including HIV infection. In this study the expression on gamma delta lymphocytes of the T cell activation markers CD25, HLA-DR and CD38, as well as the two isoforms of CD45, namely CD45RA and CD45RO, was determined in the peripheral blood of 56 HIV-infected intravenous drug users and 34 HIV-seronegative blood donors by two-colour flow cytometry. The percentage of gamma delta lymphocytes expressing HLA-DR and CD38 was higher than those in HIV-seronegative controls (P < 0.001 and P < 0.0001, respectively). Furthermore the HLA-DR+gamma delta+ lymphocytes correlated inversely with CD4+ T lymphocyte absolute count (P < 0.02 for both). The levels of gamma delta lymphocytes expressing CD25, CD45RA and CD45RO were similar to those in HIV-seronegative controls. Activated gamma delta lymphocytes may play a role in the HIV disease process and could provide a useful marker for disease progression.
