Spectrum and mortality of opportunistic infections among HIV/AIDS patients in southwestern China

Mortality and immunological indicators of men who have sex with men living with HIV on antiretroviral therapy: a 10-year retrospective cohort study in Southern China

BACKGROUND

The proportion of people living with HIV (PLHIV) in Guangxi who are men who have sex with men (MSM) increased rapidly to nearly 10% in 2023; notably, over 95% of this particular population is currently receiving antiretroviral therapy (ART). This study aimed to describe the survival of MSM PLHIV, depict the characteristics and trends of changes in CD4+ T cell counts, CD4+/CD8+ T cell ratio, and viral load, and explore immunological indicators that may be related to mortality during different stages of treatment.

METHODS

Immunological indicators of MSM PLHIV receiving ART were extracted and categorized into baseline, mid-treatment, and last values. These were then incorporated into the Cox models in the form of repeated measurements to evaluate the associations (Adjusted-hazard ratios, aHRs) and 95% confidence intervals (95% CIs) of these immunological indicators with mortality at different stages.

RESULTS

A total of 5,642 patients who met the criteria were enrolled in the study, and 160 died, representing a mortality of 2.8%. The first, median, and last values of the CD4+ count and the CD4+/CD8+ ratio in surviving patients were significantly greater than the corresponding values in nonsurviving patients (P < 0.001). Except for the first viral load (P = 0.379), the median and last viral loads of the former were significantly lower than those of the latter (P < 0.001). In Cox model, with 2,144 cases, immunological indicators of increased mortality risk included a baseline CD4+ count below 200 cells/µL (aHR: 4.58, 95% CI: 2.28-9.19), a median (aHR: 8.46, 95% CI: 3.05-23.46), and a final (aHR: 4.43, 95% CI: 1.06-18.45) ratio below 0.7 and a median (aHR: 9.47, 95% CI: 4.02-22.35) and final (aHR: 14.46, 95% CI: 4.50-46.50) viral load 100,000 copies/mL and above.

CONCLUSIONS

Mortality among MSM PLHIV on ART in Guangxi is relatively low, and both high viral loads and low CD4+/CD8+ T cell ratios during treatment and at recent follow-up are strongly predictive of a serious prognosis and should be closely monitored.

Under-nutrition and its associated factors among adult second-line antiretroviral treatment users in Northern Ethiopia

BACKGROUND

Despite advancements in Human Immunodeficiency Virus (HIV) treatment and care, undernutrition remains a significant concern, accelerating disease progression and risk of Acquired Immune Deficiency Syndrome (AIDS)-related deaths. The nutritional status of second-line antiretroviral treatment (SLART) users in Ethiopia has not been thoroughly investigated. So, this study aimed to assess the nutritional status of HIV/AIDS patients who were on SLART and its associated factors in Northern Ethiopia.

METHODS

A retrospective cross-sectional study was conducted on 366 HIV-infected adults who had been on SLART for at least six months in northern Ethiopia. Clients who had documented Weight and height at six months of therapy were included. Data was entered and cleaned by using EpiDATA version 4.6.0.2 and statistical analysis was done by STATA version 17. Multiple imputation method was applied to manage variables having up to 25% missing values by using R-Version 3.6.2 software. Binary logistic regression was used with P < 0.05 as a significant predictor in the final analysis. Data was collected from February 01 to April 30, 2021.

RESULTS

The magnitude of undernutrition among adults who were on SLART in the study area was 38.52% (95%CI: 33.65-43.64). Those populations also had a baseline undernutrition status of 39.1% (95%CI: 34.11-44.15) during their transition to SLART. The risk of being malnourished at six months of SLART initiation was fifteen times higher among those who were undernourished at SLART start (AOR:15.099, 95%CI: 8.532, 26.720) reflecting the high burden of the problem in the advanced courses of HIV/AIDS treatment and care.

CONCLUSIONS

The proportion of undernutrition among SLART users in Northern Ethiopia is high. During HIV therapy, a client's overall nutritional health is predicted by their prior undernutrition condition. This highlights the need for comprehensive nutritional assessment, counseling, and monitoring of the nutritional status of SLART users in the area with emphasis on an early identification of possible barriers to the improvement of such conditions. Promoting the consumption of nutrient-dense local foods and appropriate food preparation methods in addition to nutritional support are vital in this setting.

Evaluation of Treatment Outcomes Among Individuals on Highly Active Antiretroviral Therapy in KwaZulu-Natal, South Africa

Despite access to antiretroviral therapy (ART), South Africa has a high human immunodeficiency virus (HIV) burden. Treatment outcomes among individuals on highly active ART (HAART) in KwaZulu-Natal, with a higher incidence of HIV, are not fully known. This study evaluated the impact of HAART outcomes and identified and analyzed the factors associated with the outcomes in people living with HIV and AIDS (PLWHA) in the high-incidence region of KwaZulu-Natal Province, South Africa. This retrospective medical record review was conducted at King Edward VIII Hospital in South Africa. Data analysis was performed using STATA software Version 18.0 and Microsoft Excel 2021. The estimates used were 95% confidence intervals, and a p value < 0.05 was considered statistically significant. A total of 707 clinical records of PLWHA were examined and analyzed; less than half of them (44.98%, n = 318) achieved the benchmark of two consecutive instances of suppressed viral loads. The CD4 greater than or equal to 500 cells/mm3 at baseline average of 22.91% (n = 162) registered an increase to 48.94% (n = 346) in the 6th month and further escalated to 79.49% (n = 562) by the 12th month following ART initiation. A total of 160 deaths (mortality rate of 22.63%) were recorded within the study period. The percentage of HIV-infected patients attaining viral suppression at 6 and 12 months after initiating the treatment was respectively 44.98% and 67.04%, below the 90% target established by the Joint United Nations Program on HIV/AIDS (UNAIDS). The proportion of favorable immunological responses for individuals on ART increased over time.

Clinical aPDT's effect on Candida albicans: Antifungal susceptibility, virulence gene expression, and correlation with leukocyte and neutrophil counts

BACKGROUND

Our previous clinical trial demonstrated that antimicrobial photodynamic therapy (aPDT) with methylene blue (MB) and potassium iodide (KI) effectively killed Candida albicans (C. albicans) in adult AIDS patients with oral candidiasis, regardless of biofilm formation or 25S rDNA genotype. This study evaluated changes in antifungal susceptibility and virulence gene expression in C. albicans before and after aPDT, and explored factors related to clinical aPDT efficacy.

METHODS

Twenty-one adult AIDS patients with C. albicans oral candidiasis were divided into Group a (400 μM MB, N = 11) and Group b (600 μM MB, N = 10). Both groups received two aPDT treatments, where MB was applied for 5 min, followed by 300 mM KI, and illuminated for 30 min (37.29 J/cm²). C. albicans isolates were collected before and after treatment to assess antifungal susceptibility (fluconazole, itraconazole, flucytosine, amphotericin B) and gene expression (CAT1, HWP1). Peripheral blood tests were analyzed for correlations with aPDT efficacy.

RESULTS

aPDT reduced minimum inhibitory concentration (MIC) values for amphotericin B, fluconazole, and flucytosine, with significant reductions primarily after the first treatment. MIC reductions differed between groups, with Group a showing greater decreases in flucytosine and fluconazole MICs, and Group b in amphotericin B MICs. No significant changes in CAT1 or HWP1 expression were observed. Clinical efficacy of aPDT negatively correlated with leukocyte and neutrophil levels.

CONCLUSIONS

aPDT effectively reduces MICs of antifungal drugs against C. albicans isolated from treated patients, particularly after the first treatment. The concentration of MB required to reduce MICs varies among different antifungal drugs. aPDT does not alter CAT1 or HWP1 expression, and its clinical efficacy in eradicating C. albicans is negatively associated with leukocyte and neutrophil levels.

A Rare Modality of Concurrent Cryptococcal and Tubercular Meningitis in a Patient Living With HIV

Patients with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) and a low CD4 count have decreased humoral and cellular immunity, predisposing them to opportunistic infections. Opportunistic infections are one of the main causes of morbidity and mortality in immunocompromised individuals due to impaired immune systems, particularly in persons living with HIV/AIDS. Common opportunistic infections in patients living with HIV include bacterial infections such as Mycobacterium tuberculosis and Mycobacterium avium complex (MAC); viral infections such as cytomegalovirus (CMV) and herpes simplex virus 1 (HSV-1); fungal infections such as Pneumocystis carinii pneumonia (PCP) and cryptococcal meningitis; and parasitic infections such as cryptosporidiosis and toxoplasmosis. Concurrent infection with cryptococcal and tubercular meningitis in patients with HIV is very rare. Here, we present the case of a 48-year-old male living with HIV who presented with complaints of breathlessness, fever, and weight loss and was evaluated and put on antitubercular medications for pulmonary tuberculosis. However, the presence of a continuous headache led us to investigate further. Upon brain imaging and cerebrospinal fluid evaluation, it was determined to be meningitis due to co-infection with Mycobacterium tuberculosis and Cryptococcus neoformans. The patient was treated with antitubercular therapy along with antifungal therapy. He is under regular follow-up without any further events.

The trend of AIDS in China: A prediction and comparative analysis with G20 countries based on the Global Burden of Disease Study 2019

Background

In China, AIDS has become the most severe notifiable infectious disease. The study aimed to analyse and predict the trend of AIDS in China and compared with Group of Twenty (G20) countries.

Methods

We utilised incidence, mortality or disability-adjusted life years (DALY), age-standardised rates (ASR), average annual percentage changes (AAPC) to estimate the trend via GBD 2019. The Joinpoint regression analysis was applied to identify the most significant years of change. We explored the relationship between AAPC and social development index (SDI) or health care access and quality (HAQ), and predicted trends for the next 20 years.

Results

The DALY in G20 increase of 340.42%, and 794.50% in China. The age-standardised DALY rate (ASDR) in G20 was 309.49 (95% uncertainty interval (UI) = 284.69, 350.58) in 2019, with an AAPC of 4.30. Among G20, the United States had the highest DALY in 1990, but it experienced a significant decline. In China, the ASDR was 98.15 (95% UI = 78.78, 119.58) with the 5th AAPC ranking. In term of gender, the incidence, mortality, DALY, and ASR of them in China and G20 were all higher in males. Furthermore, the gender gap in China had been widening. The most significant periods of ASDR increase in China were 1990-1995 and 2013-2016, and 1990-1994 in G20. The prediction for DALY indicated that high SDI countries were expected to exhibit a stable or declining trend, while low SDI countries showed an upward trend. China demonstrated a 57.66% increase in 2040 compared to 2019.

Conclusions

AIDS continues to be a significant burden. In China, the ASIR exhibited a decline trend in certain age groups, while the ASMR and ASDR continued to increase, with a widening gender disparity. In addition, according to our predict results, some countries could not achieve the 2030 Agenda for Sustainable Development set by the UNAIDS. Therefore, it is necessary to establish more effective and targeted measures, as well as actively explore new treatment approaches.

Coinfections and In-Hospital Mortality in a Group of Patients With HIV/AIDS: A Longitudinal Study

Human immunodeficiency virus (HIV) is a global public health problem. Coinfections in HIV patients are frequent complications that increase their mortality. The aim of this study was to assess coinfections and in-hospital mortality in a group of patients infected with HIV in Colombia. A retrospective longitudinal study was carried out. Patients treated in 4 highly complex clinics in Colombia between 2015 and 2023 were included. The cases were identified from International Classification of Diseases codes related to HIV. Sociodemographic, clinical, laboratory and pharmacological variables were collected. Descriptive, bivariate, and multivariable analyses were performed. Of the 249 patients identified, 79.1% were men, and the median age was 38.0 years. Approximately 81.1% had a diagnosis of acquired immune deficiency syndrome (AIDS). Coinfections caused by Mycobacterium tuberculosis (24.1%) and Treponema pallidum (20.5%) were the most frequent. A total of 20.5% of the patients had sepsis, 12.4% had septic shock, and the fatality rate was 15.7%. Antibiotics and antifungals were used in 88.8% and 53.8%, respectively, of the patients. Patients with a diagnosis of HIV before admission, those infected with M. tuberculosis, and those who presented with sepsis were more likely to die, whereas patients who received antiretroviral agent treatment before admission presented a lower risk. In this study, most HIV patients were in an advanced stage of the disease. Coinfection with M. tuberculosis was common and was associated with an increased risk of death. Previous HIV diagnosis and sepsis also increased the risk. Approximately half of the patients with a previous HIV diagnosis were receiving antiretroviral therapy and had a better prognosis.

Characteristics and risk factors for readmission in HIV-infected patients with Talaromyces marneffei infection

OBJECTIVES

Talaromyces marneffei (T. marneffei) is an opportunistic fungal infection (talaromycosis), which is common in subtropical regions and is a leading cause of death in HIV-1-infected patients. This study aimed to determine the characteristics and risk factors associated with hospital readmissions in HIV patients with T. marneffei infection in order to reduce readmissions.

METHODS

We conducted a retrospective study of admitted HIV-infected individuals at the Fourth People's Hospital of Nanning, Guangxi, China, from 2012 to 2019. Kaplan-Meier analyses and Principal component analysis (PCA) were used to evaluate the effects of T. marneffei infection on patient readmissions. Additionally, univariate and multifactorial analyses, as well as Propensity score matching (PSM) were used to analyze the factors associated with patient readmissions.

RESULTS

HIV/AIDS patients with T. marneffei-infected had shorter intervals between admissions and longer lengths of stay than non-T. marneffei-infected patients, despite lower readmission rates. Compared with non-T. marneffei-infected patients, the mortality rate for talaromycosis patients was higher at the first admission. Among HIV/AIDS patients with opportunistic infections, the mortality rate was highest for T. marneffei at 16.2%, followed by cryptococcus at 12.5%. However, the readmission rate was highest for cryptococcus infection (37.5%) and lowest for T. marneffei (10.8%). PSM and Logistic regression analysis identified leukopenia and elevated low-density lipoprotein (LDL) as key factors in T.marneffei-infected patients hospital readmissions.

CONCLUSIONS

The first admission represents a critical window to intervene in the prognosis of patients with T. marneffei infection. Leukopenia and elevated LDL may be potential risk factors impacting readmissions. Our findings provide scientific evidence to improve the long-term outcomes of HIV patients with T. marneffei infection.
