Purpose of Review: This article intends to briefly discuss AIDS, summarize the current literature on immune recovery uveitis, describe its ocular manifestations and complications, and tackle its complex management., Recent Findings: The clinical picture of immune recovery uveitis is still evolving. Up to today, there are still no definite criteria for immune recovery uveitis, and although closely associated with cytomegalovirus retinitis and HIV/AIDS, there are several cases of similar intraocular response in non-HIV patients. The exact pathology for this paradoxical inflammatory reaction remains unclear; however, there is an interest in identifying biomarkers to determine underlying mechanisms and identify patients at risk. The management of this disease also remains a challenge and no standardized treatment approach exists currently., Summary: Immune recovery uveitis is an important cause of visual morbidity particularly in HIV/AIDS patients receiving highly active antiretroviral. It is a paradoxical reaction that is frequently associated with a prior cytomegalovirus retinitis infection. Although it can be a transient and self-limiting process, there is a complex decision on the timing of antiviral treatment and the initiation of antiretroviral treatment to prevent immune recovery uveitis. Furthermore, a substantial challenge arises in balancingtreatment decisions for complications in refractory cases., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background: Visceral Leishmaniasis (VL) is the most severe and fatal disease if left untreated. In people living with HIV/AIDS (PLHA), VL is considered an emerging opportunistic infection. The aim of this manuscript was to report a first case in Tunisia of a concomitant presentation of visceral and oral leishmaniasis in a patient LHA. A systematic review of the literature was performed according to PRISMA guidelines, as well., Case Presentation: The patient, a 43-year-old heterosexual man, treated for HIV/AIDS was referred for macrocheilitis of the upper and lower lips. A noticeable nodular and painless swelling extending to the cheeks' mucosa was noted. The patient's poor oral hygiene was evident due to the presence of multiple dental caries. Histological analysis of the biopsied lower lip sample revealed the presence of numerous Leishmania amastigotes. The diagnosis of VL was clinically confirmed by the presence of a mild splenomegaly and pancytopenia and biologically by the identification of the parasite using PCR Lei and the species L. infantum involved using RFLP-PCR and culture. The treatment consisted of an intravenous administration of liposomal Amphotericin B (Ambisome®, 40 mg/kg/weight) for a period of 6 weeks. A favorable outcome was noted after one year with the resolution of clinical symptoms and a negative Leishmania blood PCR test. After 2 years, the patient remained asymptomatic but showed a positive Leishmania blood PCR test. Dolutegravir® was introduced in the patient's ART regimen., Conclusions: To the best of our knowledge, this is the first case report in Tunisia of atypical VL diagnosed through an uncommon oral location in an HIV/AIDS co-infected patient . Since VL is a severe and potentially fatal disease, it is essential for dentists to perform a thorough clinical examination and adopt a multidisciplinary approach in order to ensure an early diagnosis and an effective treatment outcome., (© 2024.

Pneumocystis jirovecii pneumonia (PJP) is one of the leading opportunistic infections seen in people living with HIV. Bilateral infiltrations characterize PJP and miliary involvement is very rare. In this article, we report a 32-year-old person living with HIV who was followed up with a diagnosis of miliary PJP. Our patient was admitted to the hospital with complaints of cough, sputum, and weight loss. Initially, miliary tuberculosis was considered due to the presence of miliary involvement on chest radiography, but the diagnosis was made with P. jirovecii PCR positivity. This article aims to report a case of miliary PJP, a rare clinical form of PJP., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

A male in his 30s with a medical history of newly diagnosed HIV with a CD4 count of 292 cells/mm 3 presented with a bilateral frontal headache and left upper and lower extremity weakness and paraesthesias. A few months prior, the patient experienced a desquamating rash on his scalp and a pruritic, papular genital rash, which both self-resolved. CT head without contrast revealed extensive vasogenic oedema involving the right basal ganglia, thalamus, temporal and occipital lobes. MRI of the brain with and without contrast revealed two enhancing masses in the right lentiform nucleus and right temporal-occipital junction with associated vasogenic oedema. Cerebrospinal fluid (CSF) studies confirmed cerebral toxoplasmosis with positive CSF Toxoplasma gondii PCR and neurosyphilis with positive serum rapid plasma reagin and CSF venereal disease research laboratory test. He was treated with trimethoprim/sulfamethoxazole and intravenous penicillin G with the resolution of his symptoms., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Histoplasmosis is caused by the fungus Histoplasma capsulatum and is often fatal for individuals with acquired immunodeficiency syndrome (AIDS). Delayed diagnosis is a major factor in worsening coinfection, as it can be mistaken for other diseases. Thus, rapid identification of Histoplasma in immunocompromised patients is essential. Molecular techniques, particularly polymerase chain reaction (PCR), were used in this study to identify H. capsulatum in patients coinfected with histoplasmosis and AIDS. Blood samples from 14 individuals with AIDS and disseminated histoplasmosis were collected and analyzed. The PCR method successfully amplified the fungal region in whole blood samples, while PCR-RFLP analysis confirmed a consistent profile in the samples. Genetic sequencing further confirmed the fungal species. Compared to clinical tests such as fungal culture and urinary antigen detection, molecular analysis proved faster, more sensitive, and cost-effective. These molecular markers can potentially be incorporated into routine diagnostics in the future. Further studies are needed to expand and enhance this diagnostic approach, particularly in patients with nonprogressive clinical forms of histoplasmosis.

Seronegative human immunodeficiency virus (HIV) infection, where an HIV-specific antibody response is lacking even in chronic or late-stage HIV infections, is extremely rare. Here, we report the case of a 50-year-old Japanese man presenting with Pneumocystis pneumonia who did not produce antibodies against HIV-1 until the initiation of antiretroviral therapy (ART). Fourth-generation antigen-antibody testing temporarily reverted from weakly positive to negative soon after initiating ART, likely due to a reduction in viral load (assessed by p24 antigen levels). His HIV-1 antibody titers remained low or indeterminate even after four years of ART. A literature review suggested that the absence of HIV-1-specific antibody production may be associated with unimpeded HIV replication and rapid CD4 + T cell decline. Seronegative HIV infection can lead to deferred diagnosis and treatment, thereby increasing the risk of transmitting the virus to others or developing opportunistic illnesses. It is important to combine multiple tests for diagnosis, depending on the medical condition. Further studies are required to investigate the host factors involved in the production of HIV-1-specific antibodies., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases, and Japanese Society for Infection Prevention and Control.

A male in his 30s who was recently diagnosed with HIV arrived at the emergency department exhibiting an altered mental state and acute respiratory distress. Initial laboratory tests revealed a high anion gap metabolic acidosis, elevated liver enzyme levels and bicytopenia. A CT scan identified a miliary pattern. Bronchoscopy with bronchoalveolar lavage displayed epithelial and inflammatory cells. However, subsequent tests ruled out the presence of fungi, Pneumocystis organisms, malignancies, granulomas and viral inclusions. Broad-spectrum antibiotics with emphasis on Mycobacterium tuberculosis and antifungal treatments were administered. The regimen was adjusted after a positive urine test for the Histoplasma antigen.The patient later manifested signs and symptoms, including increased ferritin level, fever, splenomegaly, diminished natural killer cell function and heightened interleukin-2 receptor levels, confirming haemophagocytic lymphohistiocytosis. Given the patient's gravely decompensated state, the treatment incorporated dexamethasone, and the patient's vasopressor-resistant septic shock was addressed with methylene blue., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Cryptococcal meningitis (CM) causes substantial mortality in African countries with a high prevalence of human immunodeficiency virus (HIV), despite advances in disease management and increasing antiretroviral therapy (ART) coverage. Reliable diagnosis of CM is cheap and more accessible than other indicators of advanced HIV disease burden such as CD4 testing or investigation for disseminated tuberculosis; therefore, monitoring CM incidence has the potential to serve as a valuable metric of HIV programmatic success., Methods: Botswana national meningitis surveillance data from 2015 to 2022 were obtained from electronic health records. All electronic laboratory records from cerebrospinal fluid samples analyzed within government healthcare facilities in Botswana were extracted from a central online repository. Adjustments for missing data were made through triangulation with prospective cohort study datasets. CM case frequency was enumerated using a case definition and incidence calculated using national census data., Results: A total of 1744 episodes of CM were identified; incidence declined from 15.0 (95% confidence interval [CI], 13.4-16.7) cases/100 000 person-years in 2015 to 7.4 (95% CI, 6.4-8.6) cases/100 000 person-years in 2022. However, the rate of decline slowed following the introduction of universal treatment in 2016. The highest incidence was observed in men and individuals aged 40-44 years. The proportion of cases diagnosed through cryptococcal antigen testing increased from 35.5% to 86.3%., Conclusions: CM incidence has decreased in Botswana following expansion of ART coverage but persists at a stubbornly high incidence. Most cases are now diagnosed through the cheap and easy-to-use cryptococcal antigen test, highlighting the potential of using CM as key metric of program success in the Treat All era., Competing Interests: Potential conflicts of interest.

Histoplasmosis capsulatum is a dimorphic fungus, recognised for its endemic presence in multiple global regions. It may cause severe opportunistic disseminated infection in immunocompromised individuals. This is a case report of a 33-year-old man from Thailand who was admitted at a Danish hospital with fever, weight loss, cough, nosebleeds, and newly diagnosed HIV. The clinical condition rapidly deteriorated with lung and kidney failure. The patient was diagnosed with H. capsulatum fungaemia first detected on blood smear. He was treated with intravenous amphotericin B followed by oral itraconazole as well as antiretroviral therapy., (Published under Open Access CC-BY-NC-BD 4.0. https://creativecommons.org/licenses/by-nc-nd/4.0/.)

Talaromycosis marneffei (T.M) is the primary opportunistic infection of AIDS patients, and its morbidity and mortality are extremely high. To further clarify the disease characteristics of patients and provide a solid basis for in-depth exploration of their pathogenic mechanisms, we retrospectively summarized and analyzed their clinical data. We included all T.M patients tested for direct antiglobulin test (DAT) in the study. Interestingly, we found that AIDS-T.M patients had an extremely high rate of DAT positivity (92/127, 72.44%). In univariate analysis, a positive DAT was associated with blood culture of TM (P = .021), hypoproteinemia (P = .001), anemia (P = .001), thrombocytopenia (P = .003), sepsis (P = .007), and Sequential Organ Failure Assessment (SOFA) (P = .001). Hypoproteinemia, anemia, SOFA, APTT > 32.6 s, and AST > 40 U/l were studied by logistic regression. Logistic regression revealed that SOFA (OR = 1.311, P = .043), hypoproteinemia (OR = 0.308, P = .021), and anemia (OR = 0.19, P = .044) were associated with positive DAT. Positive DAT was associated with severe disease manifestations such as sepsis, and the DAT test is crucial in patients with fungemia., (© The Author(s) 2024.

Background: Mycobacterium avium complex (MAC) is an uncommon clinical pathogen, especially in the central nervous system (CNS), and carries a poor prognosis. MAC infections commonly present as immune reconstitution disease (IRD) in HIV patients. Herein, we report a case of intracranial infection caused by MAC in an AIDS patient without disseminated MAC (DMAC) and immune reconstitution inflammatory syndrome (IRIS)., Case Presentation: A 31-year-old HIV-positive male presented us with progressively worsening CNS symptoms, and neuroimaging revealed ring-enhancing lesions. The intracranial lesions worsened after the empirical therapy for toxoplasma encephalitis and fungal infection. Due to the rapid progression of the disease, the patient died. Mycobacterium avium was the only pathogen in brain tissue after cultures and molecular biology tests., Conclusion: MAC infection in CNS is challenging to diagnose in HIV patients. Our findings emphasize that obtaining tissue samples and applying molecular biology methods is essential to help diagnose the patient as soon as possible to receive adequate treatment., (© 2024.

Background: Opportunistic infections in the central nervous system (CNS) can be a serious threat to people living with HIV. Early aetiological diagnosis and targeted treatment are crucial but difficult. Metagenomic next-generation sequencing (mNGS) has significant advantages over traditional detection methods. However, differences in the cerebrospinal fluid (CSF) microbiome profiles of patients living with and without HIV with suspected CNS infections using mNGS and conventional testing methods have not yet been adequately evaluated., Methods: We conducted a retrospective cohort study in the first hospital of Changsha between January 2019 and June 2022 to investigate the microbiomes detected using mNGS of the CSF of patients living with and without HIV with suspected CNS infections. The pathogens causing CNS infections were concurrently identified using both mNGS and traditional detection methods. The spectrum of pathogens identified was compared between the two groups., Results: Overall, 173 patients (140 with and 33 without HIV) with suspected CNS infection were enrolled in our study. In total, 106 (75.7%) patients with and 16 (48.5%) patients without HIV tested positive with mNGS (p = 0.002). Among the enrolled patients, 71 (50.7%) with HIV and five (15.2%) without HIV tested positive for two or more pathogens (p < 0.001). Patients with HIV had significantly higher proportions of fungus (20.7% vs. 3.0%, p = 0.016) and DNA virus (59.3% vs. 21.2%, p < 0.001) than those without HIV. Epstein-Barr virus (33.6%) was the most commonly identified potential pathogen in the CSF of patients living with HIV using mNGS, followed by cytomegalovirus (20.7%) and torque teno virus (13.8%). The top three causative pathogens identified in patients without HIV were Streptococcus (18.2%), Epstein-Barr virus (12.1%), and Mycobacterium tuberculosis (9.1%). In total, 113 patients living with HIV were diagnosed as having CNS infections. The rate of pathogen detection in people living with HIV with a CNS infection was significantly higher with mNGS than with conventional methods (93.8% vs. 15.0%, p < 0.001)., Conclusion: CSF microbiome profiles differ between patients living with and without HIV with suspected CNS infection. mNGS is a powerful tool for the diagnosis of CNS infection among people living with HIV, especially in those with mixed infections., (© 2024 British HIV Association.)

Immunosuppressed patients can present with opportunistic infections resulting from an intrinsic systemic disease, which easily evolves into more aggressive and less common conditions. This work reports a clinical case of a female patient with histoplasmosis lesions in the nasal and oral mucosa, including pulmonary, hematological, and hepatic impairment, which led to the diagnosis of HIV seropositivity. In the presence of severe immunosuppression, morbidity is increased due to deep fungal infections and their unusual clinical characteristics can make diagnosis difficult. Therefore, it can be very helpful to recognize these clinical characteristics in order to determine early diagnostic interventions. It is important to recognize mucocutaneous manifestations of histoplasmosis because the biopsy of these lesions, and subsequent histopathological analysis, is one of the quickest, safest, and cheapest methods of diagnosis., (© 2024 Special Care Dentistry Association and Wiley Periodicals LLC.)

Purpose: Cytomegalovirus (CMV) retinitis can have debilitating impacts on quality of life (QOL), but few contemporary studies have characterized these ramifications. This study assessed the impact of CMV retinitis on vision-related QOL for those living with HIV/AIDS in Thailand., Methods: QOL was assessed as part of a prospective interventional cohort study of patients referred to a tertiary hospital in Thailand for CMV retinitis screening. A validated vision-related QOL questionnaire was administered at the baseline screening visit and at the 6-month study visit. Multivariable linear regression models were performed to determine the effect of CMV retinitis diagnosis on QOL score., Results: A total of 152 participants completed the QOL questionnaire at their initial clinic visit. At baseline, a diagnosis of CMV retinitis diagnosis was significantly associated with decreased QOL score: unilateral retinitis was associated with a 0.11 (95% CI: -0.26-0.03) decrement in QOL, and bilateral retinitis was associated with a 0.33 (95% CI: -0.51-0.16) decrement (joint P-value = 0.0009). For the 78 participants with a 6-month visit, changes in QOL from baseline were small and not significant. A diagnosis of CMV retinitis was still associated with decreased QOL score at 6 months (joint P -value = 0.03)., Conclusions: This study found that vision-related QOL was lower in those with CMV retinitis, especially with bilateral involvement, and did not improve after treatment among those with follow-up. These findings reinforce the debilitating clinical manifestations of this disease, and support efforts for earlier screening to detect CMV retinitis before impacts on QOL have occurred.

Histoplasmosis is a frequent cause of infections in people living with HIV/AIDS (PLWHA). This study introduces the application of a Histoplasma capsulatum urine antigen lateral flow assay (LFA) for diagnosing disseminated histoplasmosis in PLWHA in Suriname. The LFA's diagnostic accuracy was compared with the current diagnostic approach, aiming to assess whether this test resulted in improved early detection and management. Additionally, the prevalence of histoplasmosis among advanced stage HIV patients without clinical suspicion of infection was evaluated using the same LFA. In total, 98 patients were included in the study, of which 58 were classified as "possible disseminated histoplasmosis (DH)" based on clinical criteria and 40 as "controls". Of these possible DH cases, only 19 (32.7%) had a positive LFA. During the study, decisions for treatment were made without the treating physician being aware of the LFA result. Only 55% of the patients who started treatment for histoplasmosis based on clinical criteria had a positive LFA, and 21% of untreated patients had a positive LFA. This study shows that combining clinical signs with LFA results enhances diagnostic accuracy and is cost effective, resulting in better treatment decisions., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Woittiez et al.

Background: In Latin America, tuberculosis (TB) and histoplasmosis are two of the most frequent opportunistic infections affecting people living with human immunodeficiency virus (HIV). However, there are limited data on the clinical characteristics and outcomes of patients with concurrent TB and histoplasmosis infections., Methods: This was a retrospective observational study to describe the clinical, epidemiological and laboratory characteristics and outcomes of 21 patients living with HIV (PLHIV) who were diagnosed with concurrent histoplasmosis and TB between 2017 and 2021 in Guatemala City, Guatemala., Results: Most patients were male and were newly diagnosed with HIV. All patients had advanced HIV disease (AHD). They presented with a median CD4 count of 20 cells/µl. The most common symptoms reported by the patients were fever, weight loss, cough and diarrhoea. Twelve patients died within 6 months of baseline evaluation, for a mortality rate of 57.1%., Conclusions: PLHIV with concurrent TB and histoplasmosis infections are characterised by AHD, predominantly presenting with disseminated forms of these infections and with unspecific symptoms and signs. This evidence calls for early HIV and opportunistic infection screening and insights into the challenges and opportunities for the efficient diagnostic and therapeutic management of patients with AHD with concurrent histoplasmosis and TB infections., (© The Author(s) 2024.

Background: Cryptococcosis is an invasive, opportunistic fungal infection seen especially in human immunodeficiency virus (HIV) infected patients. Cryptococcal meningitis (CM) is the second leading cause of mortality in HIV patients. We report a case of disseminated cryptococcosis presenting with altered mental status in a newly diagnosed HIV infection., Methods and Results: A 50-year-old with a short history of altered mental sensorium and a history of low-grade fever and weight loss for few months presented at a tertiary care hospital in North India. He was detected positive for HIV-1. Cryptococcal antigen (CRAG) was positive in Cerebrospinal fluid (CSF), and negative in serum. The fungal culture in CSF was sterile while the fungal blood culture grew Cryptococcus neoformans. The patient was treated with single high-dose Liposomal Amphotericin B (LAmB) therapy followed by Fluconazole and Flucytosine for the next two weeks followed by fluconazole daily for consolidation and maintenance therapy. Antiretroviral therapy (ART) was started 4 weeks after induction therapy. After 6 months, the patient is doing fine., Conclusion: Single dose LAmB along with the backbone of fluconazole and flucytosine appears promising in disseminated cryptococcal infection in HIV-infected individuals., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Objectives: In countries with access to early antiretroviral treatment (ART), opportunistic infections caused by cytomegalovirus (CMV) in people living with HIV (PLWH) are becoming increasingly rare. As potential complications are severe, it is critical to remain aware of this important diagnosis. However, clinical characteristics and prognosis of CMV infection in PLWH in the era of modern ART have not been well described., Methods: Here, we compiled the clinical presentation, management and outcome of CMV infection in PLWH treated at the infectious diseases clinic of Karolinska University Hospital during 2010-2020., Results: We identified 51 cases of active CMV infection, based on detection of CMV-DNA, mainly diagnosed in patients with CD4 T-cell count <200 cells/μL (86%). Median time from HIV diagnosis to detection of CMV infection was 16 days. In 20 cases (39%), CMV infection was symptomatic with retinitis identified as a manifestation in 70% of cases. Symptomatic CMV infection was treated for 73 (20-313) days upon diagnosis, mostly using valganciclovir. One-year mortality was 22% and was associated with longer time to ART initiation from HIV diagnosis and with comorbidities, but not with CMV-DNA levels or CD4 count. Immune reconstitution was not significantly compromised in patients with symptomatic CMV, although CD4/8 ratio tended to be lower in patients with systemic CMV infection., Conclusions: Retinitis remains the most common manifestation of symptomatic CMV infection in PLWH. Recognizing CMV infection is important, especially in the management of 'late presenters'. Adequate duration of antiviral therapy and appropriate follow-up must be ensured to avoid complications., (© 2024 The Authors.

We assessed predictive models (PMs) for diagnosing Pneumocystis jirovecii pneumonia (PCP) in AIDS patients seen in the emergency room (ER), aiming to guide empirical treatment decisions. Data from suspected PCP cases among AIDS patients were gathered prospectively at a reference hospital's ER, with diagnoses later confirmed through sputum PCR analysis. We compared clinical, laboratory, and radiological data between PCP and non-PCP groups, using the Boruta algorithm to confirm significant differences. We evaluated ten PMs tailored for various ERs resource levels to diagnose PCP. Four scenarios were created, two based on X-ray findings (diffuse interstitial infiltrate) and two on CT scans ("ground-glass"), incorporating mandatory variables: lactate dehydrogenase, O2 sat , C-reactive protein, respiratory rate (> 24 bpm), and dry cough. We also assessed HIV viral load and CD4 cell count. Among the 86 patients in the study, each model considered either 6 or 8 parameters, depending on the scenario. Many models performed well, with accuracy, precision, recall, and AUC scores > 0.8. Notably, nearest neighbor and naïve Bayes excelled (scores > 0.9) in specific scenarios. Surprisingly, HIV viral load and CD4 cell count did not improve model performance. In conclusion, ER-based PMs using readily available data can significantly aid PCP treatment decisions in AIDS patients., (© 2024. The Author(s).)

Background: HIV-associated tuberculosis (TB) contributes disproportionately to global tuberculosis mortality. Patients hospitalised at the time of the diagnosis of HIV-associated disseminated TB are typically severely ill and have a high mortality risk despite initiation of tuberculosis treatment. The objective of the study is to assess the safety and efficacy of both intensified TB treatment (high dose rifampicin plus levofloxacin) and immunomodulation with corticosteroids as interventions to reduce early mortality in hospitalised patients with HIV-associated disseminated TB., Methods: This is a phase III randomised controlled superiority trial, evaluating two interventions in a 2 × 2 factorial design: (1) high dose rifampicin (35 mg/kg/day) plus levofloxacin added to standard TB treatment for the first 14 days versus standard tuberculosis treatment and (2) adjunctive corticosteroids (prednisone 1.5 mg/kg/day) versus identical placebo for the first 14 days of TB treatment. The study population is HIV-positive patients diagnosed with disseminated TB (defined as being positive by at least one of the following assays: urine Alere LAM, urine Xpert MTB/RIF Ultra or blood Xpert MTB/RIF Ultra) during a hospital admission. The primary endpoint is all-cause mortality at 12 weeks comparing, first, patients receiving intensified TB treatment to standard of care and, second, patients receiving corticosteroids to those receiving placebo. Analysis of the primary endpoint will be by intention to treat. Secondary endpoints include all-cause mortality at 2 and 24 weeks. Safety and tolerability endpoints include hepatoxicity evaluations and corticosteroid-related adverse events., Discussion: Disseminated TB is characterised by a high mycobacterial load and patients are often critically ill at presentation, with features of sepsis, which carries a high mortality risk. Interventions that reduce this high mycobacterial load or modulate associated immune activation could potentially reduce mortality. If found to be safe and effective, the interventions being evaluated in this trial could be easily implemented in clinical practice., Trial Registration: ClinicalTrials.gov NCT04951986.

Background: Immunodeficient patients, particularly HIV patients, are at risk of opportunistic infections. Nontuberculous mycobacteria can cause severe complications in immunodeficient patients., Case Presentation: We describe a 57-year-old HIV patient, primarily presented with coughs and constitutional symptoms, with a unique Mycobacterium genavense abdominal, pulmonary, and central nervous system infection, accompanied by intracranial masses., Conclusion: The diagnosis of NTM, including M. genavense, must always be considered by clinicians in immunodeficient patients, especially those with HIV, who have a compromised immune system., (© 2024.

Introduction: Management of patients living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (AIDS) (PLWHA) still represents a challenge for doctors in various medical fields. The presence of co-infections, with different degrees of immune system impairment, raises the need for a multi-disciplinary approach to the PLWHA. Methods: In this paper, we present three cases of PLWHA with various ophthalmological conditions, who were admitted to "Prof. Dr. Matei Balș" National Institute for Infectious Diseases (INBIMB). Three of them were late presenters, recently diagnosed with AIDS. All three were in immuno-virological failure. The ophthalmic conditions were either related to the HIV infection, or the result of other complications. Discussion: The diversity and complexity of ocular involvement in PLWHA were deeply linked to the patient's immunological status at the ophthalmological evaluation moment. Thus, antiretroviral therapy (ART) played an important immune status recovery role. Encountered ocular conditions vary, some being directly caused by the presence of the virus, and the others were the result of opportunistic infections (cytomegalovirus, Varicella virus) or other co-infections (Treponema pallidum). Neurological conditions disturbing the natural defense mechanism, prolonged hospital stay, and exposure to multiple antibiotic regimens are risk factors for difficult-to-treat eye infections with multidrug-resistant bacteria. Some ocular conditions can be the reason that leads to HIV infection diagnosis, while others can appear during the time, especially in patients with low ART adherence. The prognostic is conditioned by the early recognition and correct management of the disease and the immunological status recovery under ART. Conclusions: Correct and early diagnosis of HIV-related eye conditions is mandatory to establish the most appropriate medical management to obtain an increase in the quality of life of the patient.

Introduction: Ocular involvement in human immunodeficiency virus (HIV) infected and treatment-experienced patients is a significant concern, despite the advancements in antiretroviral therapy (ART) medication. The extended life expectancy of HIV patients has altered the spectrum of HIV-associated ocular diseases, ranging from minor issues to severe vision impairment or blindness. Therefore, understanding these complications becomes crucial in providing comprehensive medical care and quality of life improvement. HIV patients on multiple ARTs can experience various ocular disorders due to the complexity of their treatment regimens, drug toxicities, immune reconstitution, and opportunistic infections. Most worthy to consider are: cytomegalovirus (CMV) retinitis, immune recovery uveitis (IRU), keratoconjunctivitis sicca (dry eye syndrome), and HIV-associated neuroretinal disorders. Materials and methods: A retrospective clinical investigation was conducted on HIV/AIDS-infected patients from January 1, 2013, to December 31, 2023. The study included 62 patients over 18 years, who tested HIV-positive via enzyme-linked immunosorbent assay (ELISA) and confirmed by Western blot (WB), with assessments of HIV plasma viral load (VL) and CD4+ T cell counts (CD4). Data collected included demographics, pathological histories, clinical characteristics, blood tests, assessments for opportunistic infections, patient staging, antiretroviral therapy initiation, and disease prognosis. Results: The study found that of most patients, 37 were aged 30-39 (59.7%), with 59.7% males and 40.3% females. Most had been living with HIV for 10-19 years (35.5%). Initial CD4 counts were < 200 cells/mm3 in 46.8% of patients, which improved to 19.3% when the study was done. CMV retinitis prevalence decreased from 46.8% initially to 35.5% despite ART. Other conditions included ocular toxoplasmosis (3.22%), tuberculosis-related uveitis (1,6%), keratoconjunctivitis sicca (19.3%), and HIV retinopathy (29%). Notably, 62.1% of CMV retinitis patients experienced significant visual acuity reduction. Oral valganciclovir was beneficial for patients with CMV disease affecting multiple sites and effective for both induction and maintenance therapy of CMV retinitis. Conclusions: Managing ocular complications in HIV-experienced patients requires a multidisciplinary approach with regular ophthalmologic evaluations, prompt treatment of infections, and continuous monitoring of ART effectiveness. Early detection and intervention are crucial for preserving vision and improving outcomes. The study highlighted the importance of constant monitoring even after viral suppression.

Background: Cryptococcal meningitis (CM), an opportunistic fungal infection affecting immunocompromised hosts, leads to high mortality. The role of previous exposure to glucocorticoids as a risk factor and as an outcome modulator has been observed, but systematic studies are lacking., Objective: The primary aim of this study is to evaluate the impact of glucocorticoid use on the clinical outcomes, specifically mortality, of non-HIV and non-transplant (NHNT) patients diagnosed with CM., Methods: We queried a global research network to identify adult NHNT patients with CM based on ICD codes or recorded specific Cryptococcus CSF lab results with or without glucocorticoid exposure the year before diagnosis. We performed a propensity score-matched analysis to reduce the risk of confounding and analysed outcomes by glucocorticoid exposure. We used a Cox proportional hazards model for survival analysis., Results: We identified 764 patients with a history of glucocorticoid exposure and 1267 patients without who developed CM within 1 year. After propensity score matching of covariates, we obtained 627 patients in each cohort. The mortality risk in 1 year was greater in patients exposed to prior glucocorticoids (OR: 1.3, CI: 1.2-2.0, p = 0.002). We found an excess of 45 deaths among CM patients with previous glucocorticoid use (7.4% increased absolute risk of dying within 1 year of diagnosis) compared to CM controls without glucocorticoid exposure. Hospitalisation, intensive care unit admission, emergency department visits, stroke and cognitive dysfunction also showed significant, unfavourable outcomes in patients with glucocorticoid-exposed CM compared to glucocorticoid-unexposed CM patients., Conclusions: Previous glucocorticoid administration in NHNT patients seems to associate with 1-year mortality after CM adjusted for possible confounders related to demographics, comorbidities and additional immunosuppressive medications. Serial CrAg screening might be appropriate for higher-risk patients on glucocorticoids after further cost-benefit analyses., (© 2024 Wiley-VCH GmbH. Published by John Wiley & Sons Ltd.)

HIV infection alters the skin microbiome and predisposes to a wide range of cutaneous infections, from atypical presentations of common skin infections to severe disseminated infections involving the skin that are AIDS-defining illnesses. Bacterial infection of the skin, most commonly caused by Staphylococcus aureus, occurs frequently and can result in bacteremia. Nontuberculous mycobacterial infections that are usually localized to the skin may disseminate, and guidance on the treatment of these infections is limited. Herpes simplex can be severe, and less common presentations such as herpetic sycosis and herpes vegetans have been reported. Severe herpes zoster, including disseminated infection, requires intravenous antiviral treatment. Viral warts can be particularly difficult to treat, and in atypical or treatment-resistant cases a biopsy should be considered. Superficial candidosis occurs very commonly in people living with HIV, and antifungal resistance is an increasing problem in non-albicans Candida species. Systemic infections carry a poor prognosis. In tropical settings the endemic mycoses including histoplasmosis are a problem for people living with HIV, and opportunistic infections can affect those with advanced HIV in all parts of the world. Most cutaneous infections can develop or worsen as a result of immune reconstitution in the weeks to months after starting antiretroviral therapy. Direct microscopic examination of clinical material can facilitate rapid diagnosis and treatment initiation, although culture is important to provide microbiological confirmation and guide treatment., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2023 Elsevier Inc.

Background: Opportunistic infections (OIs) among newly diagnosed HIV patients are a marker for inadequateness of HIV awareness and testing. Despite global efforts at creating awareness for early detection, late HIV diagnosis and its associated OIs still exist. This study sought to determine the prevalence and patterns of OIs and associated factors among newly diagnosed HIV patients in Ghana., Methods: A retrospective study using data extraction was conducted among 423 newly diagnosed HIV patients aged ≥18 years at the Korle-Bu Teaching Hospital from July 1 st 2018 to December 2019. Multivariate logistic regression was adopted to assess factors associated to OIs. Analysis was performed using SPSS version 16, and p-value < 0.05 was deemed significant., Results: The mean age of patients with a new HIV diagnosis was 40.15 ± 11.47 years. Male versus female sex differential was 30.3% and 69.7%, respectively. The prevalence of OIs among newly diagnosed HIV patients was 33.1% (95% CI = 34.6-44.1). About 70% (120/166) of patients with OIs were classified into WHO clinical stage III and IV. The most common OIs were candidiasis (oro-pharyhngeal-esophageal) (36.9%), and cerebral toxoplasmosis (19.9%). The odds of an OI at the time of HIV diagnosis among females was 51% lower than in males (aOR = 0.49, 95% CI = 0.28-0.86). Being employed increased the odds of OIs by 2.5 compared to the unemployed (aOR = 2.5; 95% CI = 1.11-5.61). Participants classified as World Health Organization (WHO) HIV clinical stage III and IV were 15.88 (95% CI = 9.41-26.79) times more likely to experience OIs., Conclusion: One in three patients newly diagnosed with HIV presented with an opportunistic infection, with men more likely to experience such infections. Significant attention should be given to improving case-finding strategies, especially among men., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2024 The Author(s).)

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. It is currently considered a public health problem due to the socioeconomic conditions of the world population and the increase in other infections such as that due to Human Immunodeficiency Virus (HIV). Pulmonary involvement is the most common form of clinical presentation, although in recent decades extrapulmonary involvement has increased. Among these, digestive disorders represent less than 10%. We present a case of exclusive pancreatic tuberculosis, in the context of an immunocompromised patient. A 43-year-old man with a history of HIV with a low CD4 count and high viral load, without antiretroviral treatment, with one-month history of symptoms characterized by low-grade fever associated with weight loss and nonspecific abdominal pain. An abdominal tomography was performed which showed a collection in the tail of the pancreas; the puncture revealed material with positive culture for M. tuberculosis. Antifimic and antiretroviral treatment was started with a good response. Primary pancreatic tuberculosis is an uncommon extrapulmonary form, given that it is a gland that would be biologically protected by the enzymes it produces. We highlight the rarity of the case and although the prognosis is good with anti-tuberculosis treatment, it could be fatal without correct diagnosis and treatment. The high index of suspicion of pancreatic tuberculosis by the physician and the performance of fine needle aspiration puncture to obtain histopathological evidence are important for a correct diagnosis, especially in HIV patients.

BACKGROUND The highly active antiretroviral treatment (HAART) and the primary prophylaxis in newly diagnosed people living with HIV (PLHIV) have reduced the incidence of opportunistic infections such as cryptococcal meningitis (CM). Relapse of CM is associated with increased morbidity and mortality. The aim of the present case presentation is to report the clinical progress relapse of CM in a man who was a late presenter PLHIV, 1 year after ART initiation with increased CD4 cell count, undetectable viral load, and excellent compliance after disruption of secondary antifungal prophylaxis. CASE REPORT One year after initial diagnosis of HIV and CM, the patient had no neurological or other symptoms, and viral suppression and increased CD4 cell count were achieved. After the completion of 12 months of secondary prophylaxis with fluconazole, an episode of partial seizure with secondary generalization occurred, followed by a short-term memory loss. Magnetic resonance imaging (MRI) indicated a focal lesion in right frontal-parietal brain region. Lumbar puncture was conducted and Cryptococcus neoformans non-resistant to fluconazole was isolated. He received antiepileptic treatment, induction antifungal treatment with liposomal amphotericin and fluconazole, consolidation treatment with fluconazole, and secondary prophylaxis with fluconazole, as in the first episode of CM. One year after the relapse, antiepileptic treatment and secondary prophylaxis with fluconazole continues and no new episode has been reported. The diagnosis of immune reconstitution inflammatory syndrome (IRIS)-related relapse of CM cannot be excluded. CONCLUSIONS Further studies are needed for the evaluation of parameters such as duration of secondary prophylaxis and treatment options for induction and consolidation therapy to reduce the relapse rate of CM.

Background: Histoplasmosis is mainly described as a disseminated disease in people living with HIV (PLHIV). Compared to historical descriptions in immunocompetent individuals, knowledge is lacking on the detailed clinical and radiological findings and outcomes of pulmonary histoplasmosis (PH). Overlooked or misdiagnosed with other AIDS-defining condition, prognostic of PLHIV may be at risk because of inappropriate care., Methods: A retrospective multicentric study was conducted in PLHIV from French Guiana between January 1988 and October 2019. Proven PH were documented through mycological direct examination, culture, or histology. Patients with concomitant respiratory infections were excluded., Results: Among 65 patients, sex ratio M:F was 2.4 with a median age of 39 years [IQR 25-75%: 34-44]. Median CD4 count was 24 cells/mm 3 [11-71], with histoplasmosis as the AIDS-defining condition in 88% and concomitant AIDS-defining conditions in 29%. Clinical findings were fever (89%), cough (58%), dyspnea (35%), expectoration (14%), and hemoptysis (5%). Sixty-one X-rays and 24 CT-scans were performed. On X-rays, an interstitial lung disease was mainly found (77%). On CT-scans, a nodular pattern was predominant (83%): mostly miliary disease (63%), but also excavated nodules (35%). Consolidations were present in 46%, associated with miliary disease in 21%. Thoracic lymphadenopathies were found in 58%, mainly hilar and symmetric (33%). Despite antifungal treatment, case-fatality rate at one month was 22%., Conclusion: When faced with an interstitial lung disease on X-rays or a miliary pattern on CT-scans in advanced PLHIV, physicians in endemic areas, apart from tuberculosis or pneumocystosis, should include histoplasmosis as part of their differential diagnoses., (© 2023.

To date, the identification of crypotococcal relapse remains clinically challenging as it often has similar manifestation with paradoxical immune reconstitution inflammatory syndrome. This study reports on the use of metagenomics assisted next generation sequencing to aid in diagnosing recurrent cryptococcal meningitis in an person living with HIV experiencing recurring symptoms, despite negative culture results for Cryptococcus neoformans in the cerebrospinal fluid. Although fungal culture was negative, when reads from metagenomic and metatranscriptomic sequencing performed on the Day 308 cerebrospinal fluid sample were mapped onto the genome from the Day 4 isolate, 589 specific reads were identified. NCBI BLAST search also revealed Cryptococcus -specific 18S/25S/28S ribosomal RNA, indicating a relapse of the disease.

Objectives: We investigated whether patients with cryptococcal meningitis (CM) or fungaemia detected through South Africa's laboratory cryptococcal antigen (CrAg) screening programme had better outcomes than those presenting directly to the hospital., Methods: We compared 14-day in-hospital case-fatality ratios of HIV-seropositive individuals with CD4 counts below 100 cells/μL and laboratory-confirmed CM/fungaemia from 2017-2021, with or without evidence of a positive blood CrAg test within 14 days prior to diagnosis. We evaluated whether the impact of prior CrAg screening on mortality varied according to the study period (pre-COVID-19: before March 2020 vs. COVID-19: after March 2020)., Results: Overall, 24.5% (830/3390) of patients had a prior positive CrAg test within 14 days of diagnosis. CrAg-screened patients were less likely to have an altered mental status at baseline than non-CrAg-screened patients (38.1% [296/776] vs. 42.6% [1010/2372], p = 0.03), and had a lower crude 14-day case-fatality ratio (24.7% [205/830] vs. 28.3% [724/2560]; OR, 0.83 [95% CI, 0.69-0.99]; p = 0.045). Previous CrAg screening was associated with a greater reduction in the crude 14-day mortality during the COVID-19 period (OR, 0.64 [0.47-0.87]; p = 0.005) compared with before (OR, 0.95 [0.76-1.19]; p = 0.68). After adjustment, previous CrAg screening within 14 days was associated with increased survival only during the COVID-19 period (adjusted OR, 0.70 [0.51-0.96]; p = 0.03)., Discussion: Previous CrAg screening was associated with a survival benefit in patients hospitalized with CM/fungaemia during the COVID-19 period, with fewer patients having an altered mental status at baseline, suggesting that these patients may have been diagnosed with cryptococcosis earlier., (Copyright © 2023 European Society of Clinical Microbiology and Infectious Diseases.

Objectives: The burden of histoplasmosis is as great as that of tuberculosis in Latin America and the attributable mortality is even higher. A better assessment of severity could help reduce mortality., Methods: From the French Guiana HIV-histoplasmosis database, we attempted to identify factors associated with 30-day death after antifungal drug initiation and constructed a prognostic score. We evaluated its discrimination performance using several resampling methods., Results: Of the 415 patients included, 56 (13.5%) died within 30 days of treatment. The fatality-associated factors were performance status ≥3, altered mental status, dyspnea, C-reactive protein ≥75 mg/l, hemoglobin <9 g/dl and/or a platelet <100000/ml, and an interstitial lung pattern on chest X-ray. We constructed a 12-point prognostic score. A threshold ≥5 classified patients as alive or dead at 30 days with a sensitivity of 84%, a specificity of 81%, a positive predicted value of 40%, and a negative predicted value of 97%. The area under the curve of the receiver operating characteristic curves from the different resamples were stable between 0.88 and 0.93., Conclusion: The histoplasmosis case fatality score, which is easy and inexpensive to perform, is a good tool for assessing severity and helping in the choice of induction therapy. An external validation remains necessary to generalize these results., Competing Interests: Declaration of competing interest The authors have no competing interests to declare., (Copyright © 2023 The Author(s).

Cryptococcal infection is a life-threatening, opportunistic infection in human immunodeficiency virus-infected individuals. The infection most commonly begins in the respiratory tract, with secondary involvement of the brain, skin, and lymph nodes. We report a rare case of isolated cervical cryptococcal lymphadenitis diagnosed on fine needle aspiration cytology, which was the initial presentation of secondary immunodeficiency in the patient. Periodic acid-Schiff stain, India ink preparation, and culture were done to confirm the diagnosis. He was diagnosed as HIV-positive on further investigation., (© 2023 John Wiley & Sons Ltd.)

Background: Respiratory symptoms are the earliest clinical manifestation of Talaromyces marneffei (TM) infection. In this study, we aimed to improve the early identification of TM infection in human immunodeficiency virus (HIV)-negative children with respiratory symptoms as the first manifestation, analyze the risk factors, and provide evidence for diagnosis and treatment., Methods: We retrospectively analyzed six cases of HIV-negative children with respiratory system infection symptoms as the first presentation., Results: All subjects (100%) had cough and hepatosplenomegaly, and five subjects (83.3%) had a fever; other symptoms and signs included lymph node enlargement, rash, rales, wheezing, hoarseness, hemoptysis, anemia, and thrush. Additionally, 66.7% of the cases had underlying diseases (three had malnutrition, one had severe combined immune deficiency [SCID]). The most common coinfecting pathogen was Pneumocystis jirovecii, which occurred in two cases (33.3%), followed by one case of Aspergillus sp. (16.6%). Furthermore, the value of β-D-glucan detection (G test) increased in 50% of the cases, while the proportion of NK decreased in six cases (100%). Five children (83.3%) were confirmed to have the pathogenic genetic mutations. Three children (50%) were treated with amphotericin B, voriconazole, and itraconazole, respectively; three children (50%) were treated with voriconazole and itraconazole. All children were tested for itraconazole and voriconazole plasma concentrations throughout antifungal therapy. Two cases (33.3%) relapsed after drug withdrawal within 1 year, and the average duration of antifungal treatment for all children was 17.7 months., Conclusion: The first manifestation of TM infection in children is respiratory symptoms, which are nonspecific and easily misdiagnosed. When the effectiveness of anti-infection treatment is poor for recurrent respiratory tract infections, we must consider the condition with an opportunistic pathogen and attempt to identify the pathogen using various samples and detection methods to confirm the diagnosis. It is recommended the course for anti-TM disease be longer than one year for children with immune deficiency. Monitoring the blood concentration of antifungal drugs is important., (© 2023.

Despite advances in diagnostic, therapeutic and preventive strategies for HIV, pulmonary diseases continue to be the major cause of morbidity and mortality in infants and children infected with HIV. With effective programs to prevent perinatal HIV-1 transmission to early diagnosis in infants, we have seen a substantial decline in paediatric HIV incidence. Early initiation of Highly Active Anti-Retroviral Therapy (HAART) in all HIV infected children coupled with consistent use of Pneumocystis prophylaxis in all HIV exposed/infected children under 5 years of age has considerably reduced associated infections overall and respiratory infections in particular. In developing countries already burdened with poverty, malnutrition, suboptimal immunization coverage and limited access to health care and treatment, acute and chronic HIV-associated respiratory disease remain a major cause for concern. Prevention of severe respiratory infections in advanced HIV disease among children consists mostly of rapid and optimal HAART initiation & continuation, preventing severe TB disease with BCG and TB preventive treatment, preventing Pneumocystis jirovecii pneumonia with cotrimoxazole prophylaxis and administering age-appropriate vaccinations and catch-up vaccines as per National Immunization schedule., Competing Interests: Conflicts of interest The author has none to declare., (Copyright © 2023 Tuberculosis Association of India.

Objective: Aim: To the aim of our study is to draw attention to the need to take into account HIV infection and its complications, such as CNS toxoplasmosis, in the differential diagnosis of people presenting with impaired consciousness. We analyzed our patient's medical records and available statistical data on HIV infection, as well as literature on nervous system involvement in the course of AIDS., Patients and Methods: Materials and Methods: In our paper, we present the case of a 43-year-old male who was admitted to a neurological ward due to impaired consciousness. Diagnostic imaging and laboratory tests were conducted, and patient was diagnosed with toxoplasmosis in the course of AIDS., Conclusion: Conclusions: HIV infection is a global public health problem. In the absence or ineffectiveness of treatment, it leads to profound immunodeficiency and, consequently, opportunistic infections. One of them is the reactivation of the latent Toxoplasma gondii infection. It is the most common cause of extensive cerebral lesions in patients infected with the HIV virus. In these cases, MRI reveals numerous scattered ring-enhancing lesions. The symptoms are non-specific: headaches, impaired consciousness, convulsions, behavioral changes, and focal neurological deficits. The onset of neurological symptoms may be the first clinically relevant manifestation of AIDS. It is key to diagnose such patients as soon as possible and treat them accordingly.

Background: There is scarce information on AIDS-related cytomegalovirus (CMV) retinitis in middle-income countries. The objectives of this study were to identify the prevalence of active CMV retinitis in severely immunosuppressed people living with HIV (PLWHIV) and to describe its main features., Methods: This retrospective cohort study was carried out at a tertiary center in São Paulo, Brazil. We included hospitalized adults PLWHIV with CD4 count ≤100 cells/μL, ≥ one quantitation of CMV DNA in plasma, and indirect ophthalmoscopy evaluation., Results: Thirty-eight (21.6%) of 176 participants had at least an ophthalmoscopy diagnosis and only 3 (1.7%) individuals presented active CMV retinitis. All these participants were male, and retinitis was asymptomatic in 2 cases. Two participants had extraocular end-organ CMV disease and detectable CMV DNA in plasma., Conclusions: These results show a low prevalence of active CMV retinitis in the evaluated population. However, 2 of 3 participants had asymptomatic active CMV retinitis and a fifth of participants had at least one ophthalmoscopy diagnosis, suggesting the need for routine ophthalmologic evaluation in hospitalized severely immunosuppressed PLWHIV. The profile of participants with active CMV retinitis was similar to that described in the pre-ART era and quantitation of CMV DNA in plasma was variable.

We describe the opportunistic infections (OIs) of HIV/AIDS to understand the spectrum, mortality, and frequency of multiple coinfected OIs among HIV/AIDS patients in southern China, where OIs are severe. We carried out a retrospective cohort study of hospitalized HIV-infected individuals at the Fourth People's Hospital of Nanning, Guangxi, China, from Jan. 2011 to May. 2019. The chi-square test was used to analyze cross-infection; the Kaplan‒Meier analysis was used to compare mortality. A total of 12,612 HIV-infected patients were admitted to this cohort study. Among them, 8982 (71.2%) developed one or more OIs. The overall in-hospital mortality rate was 9.0%. Among the patients, 35.6% coinfected one OI, and 64.4% coinfected more than two OIs simultaneously. Almost half of the patients (60.6%) had CD4 + T-cell counts < 200 cells/μL. Pneumonia (39.8%), tuberculosis (35.3%), and candidiasis (28.8%) were the most common OIs. Coinfected cryptococcal meningitis and dermatitis are the most common combined OIs. The rate of anaemia (17.0%) was highest among those common HIV-associated complications. Multiple OIs are commonly found in hospitalized HIV/AIDS patients in southwestern China, which highlights the need for improved diagnosis and treatment., (© 2022. The Author(s).)
