Human Immunodeficiency Virus Associated Neuropathy Perinatally Infected HIV Children In Calabar, Nigeria. Clinical Features, Treatment and Outcome

Background Renal disease is increasing being recognized as a significant cause of morbidity and mortality in HIV positive patients. Human Immunodeficiency virus associated nephropathy (HIVAN) is the most common type of HIV related renal disease and rapidly progress to end stage renal disease(ESRD). There is paucity of report on true prevalence of HIVAN in African. This study was aimed at determining the prevalence of HIVAN, clinical features, treatment and outcome, in Calabar Nigeria. Methods/Subject This was a retrospective review of all renal patients managed by Pediatric nephrology unit of University of Calabar Teaching Hospital from January 2016 to December 2022 enrolled in the Renal register. During the period of study 215 patients had renal diseases out of which 15 had HIVAN. The following information were extracted from the HIVAN patients; Demographics and clinical data as well as mode of transmission, laboratory investigations, renal Ultrasound scan, treatment and Outcome were obtained and analyzed using SPSS version 20. Results There were 215 cases of renal diseases seen during the study period of which 15 had HIVAN giving a prevalence of 6.9% There were 5 males and 10 females giving a ratio of 1:2, age range 69-192months. with a mean age of 127±43.7months All received HAART and had acquired HIV infection through vertical transmission. 8 (53%) of patient were asymptomatic with 6 (40%) presenting with both legs and facial swelling. Nephrotic range proteinuria was a common presentation seen in 40% of the patients and 5(33.3%) had hypertension. Only 4 (33%) had eGFR<60 ml/min/1.73m2 and 2(16%) had ESRD. Two were lost to follow-up and 4 (26%) died with two requiring dialysis. Conclusion HIVAN is common in patients with renal diseases and there is need to monitor patient at initiation of HAART and at risk patients with low CD4+ count and exposure to nephrotoxic HAART.

Seroprevalence and risk factors of Toxoplasmosis in HIV positive and negative patients attending the Bamenda Regional Hospital, North West Region, Cameroon

Background: Toxoplasmosis, caused by Toxoplasma gondii, can infect almost all warm-blooded animals including humans. T. gondii is regarded as an important opportunistic pathogen that can cause infection in HIV/AIDS patients associated with high mortality. The objective of this study is to determine the prevalence and risk factors of T. gondii infection in HIV-positive and negative patients and establish the relationship between HIV viral load and active toxoplasmosis in the Bamenda Regional Hospital Cameroon. Methodology: Three hundred and three (201 HIV-positive and 102 HIV-negative) participants attending the Bamenda Regional Hospital, Cameroon, were randomly recruited into the study. Well-structured questionnaires were used to obtain information on demographic characteristics and potential risk factors from each participant. Venous blood samples were collected for serological detection of toxoplasmosis using One-Step Toxo IgG/IgM rapid diagnostic test (RDT) kits, followed by confirmation of all positive samples by Toxoplasma IgM ELISA test. Data were analysed on SPSS version 23.0. Association of potential risk factors with seroprevalence of toxoplasmosis was done using Chi square test, and comparison of means HIV loads between participant categories was done using Mann-Whitney U-test and Kruskal-Wallis as applicable, with p<0.05 considered as significant level. Results: Of the 303 participants, 93 were positive for Toxoplasma IgG, giving latent toxoplasmosis seroprevalence rate of 30.7%, while 2 of the 303 participants were seropositive for Toxoplasma IgM, indicating active toxoplasmosis in 0.7%. The seroprevalence of latent toxoplasmosis was 28.9% (n=58/201) in HIV-positive compared to 34.3% (n=35/102) in HIV-negative participants (χ2=0.948, OR=0.775, p=0.330), while the seroprevalence of active toxoplasmosis was 1.0% (n=2/201) in HIV-positive compared to 0% (n=0/102) in HIV-negative participants (χ2=0.068, OR=2.568, p=0.552). Viral load was detectable (≥ 42 viral copies/ml) in 54 of the 201 HIV-positive participants, giving an overall detectable viral load rate of 26.9%. The sero-prevalence of latent toxoplasmosis was higher in HIV-positive participants with detectable viral load than those with non-detectable viral load, and the two HIV-positive patients with active toxoplasmosis had detectable viral loads. The risk factors significantly associated (p<0.05) with the latent toxoplasmosis were owning a cat, presence of stray cats, playing with cats, and eating soya. Conclusion: Latent toxoplasmosis is prevalent among HIV-positive and negative patients attending the Bamenda Regional Hospital in Cameroon, with active infection only among HIV-infected patients.

The impact of concurrent HIV-infection on women with vulvar cancer: Comparison of clinical characteristics and outcome.

HPV-related vulvar cancer is increasing in prevalence, especially in women living with HIV. Treatment of vulva cancer is based on evidence from HPV-independent cancers, which affect older women. The impact of HIV on vulvar cancer characteristics and treatment outcomes needs to be elucidated. A retrospective observational study compared the clinical characteristics, treatment, and outcomes of 92 HIV-positive and 131 HIV-negative women with vulvar cancer at our institution. Using descriptive statistics, HIV-positive and negative patients were compared and Cox regression models were tested for differences in mortality and recurrence. HIV-positive patients were 20 years younger than HIV-negative patients (p < 0.001). More than 50% of patients presented with advanced stage cancer, however this was independent of HIV-status. Although HIV infection was associated with poorer survival (p = 0.022); rates of cure (p = 0.933) and recurrence rates (p = 0.8) were similar in HIV-positive and negative women. Vulvar cancer occurs at a much younger age in women living with HIV. Awareness among HIV-positive women and health care providers would lead to diagnosis of vulvar cancer at an earlier stage. Treatment protocols for HPV-related vulvar cancer should not be altered due to HIV status and should take into consideration the young age of the patients.

A-248 Assessment of Nanopore Sequencing for HIV Genotyping: A Comparative Study with Sanger Sequencing

Abstract Background The HIV drug resistance test, conducted through genotyping of the Human Immunodeficiency Virus (HIV), is a critical tool for assessing drug resistance in virus-infected patients and is commonly performed using Sanger Sequencing methodology (first-generation sequencing). Nanopore sequencing (third-generation sequencing) is a new technology that started to be commercialized a few years ago and has recently undergone significant updates with the new Q20+ chemistry. Therefore, this study aims to evaluate the potential use of nanopore sequencing (MinION) for HIV genotyping. Methods The genomic region encoding HIV protease and transcriptase was amplified by nested PCR using primer pairs modified with unique barcodes in the second round of amplification. Three libraries were assembled, including samples from 22 HIV-positive patients, one negative control (negative control patient), and one no-template control (NTC) per library, totaling 66 HIV-positive samples. The libraries were constructed using the SQK-LSK114 kit and sequenced on a MinION platform using the new Q20+ chemistry in flowcells or flongle R10.4.1. The sequences were assembled and analyzed using HIVdb-NGS (Stanford). Validation tests, such as accuracy and precision, were conducted following WHO recommendations for HIV genotyping. The same samples were also sequenced using the Sanger method for comparison. Results 62 HIV sequences were generated by the MinION and analyzed in the described pipeline. The average sequence coverage per sample was 25,866 x. 41 sequences were classified as type B (63.08%), 12 as type C (18.46%), 8 as type F (12.31%), three as CRF02_AG (4.62%), and 1 as a recombinant B+C (1.54%). All identified subtypes were consistent with those found by the Sanger method. The average similarity between the sequences of each sample (MinION vs Sanger) was 98.68% (minimum 94.96%, maximum 99.95%). Basecalling similarity at relevant positions (associated with resistance) was above 98% in 59 out of 62 samples (95.16%), meeting the acceptance criteria recommended by the WHO. Conclusions Our results suggest that nanopore sequencing (utilizing Q20+ chemistry) can replace Sanger sequencing for HIV genotyping, which is used to monitor the effectiveness of anti-HIV drugs. This transition will allow for a reduction in test costs in laboratories with high demand for HIV drug resistance testing. Additionally, the use of modified primers proposed here eliminates the need for commercial barcodes, resulting in reduced processing time and improved throughput.

Femoral head and acetabular necrosis combined with hip subluxation in people with HIV: a case report and literature review

IntroductionHIV is widely prevalent in all regions of the world. The use of antiretroviral drugs has dramatically reduced the mortality rate of HIV-related diseases, but correspondingly increased the incidence of chronic complications in HIV-positive people. Related studies have found that the incidence of osteonecrosis of the femoral head is higher in HIV-positive people, but the co-occurrence of femoral head necrosis, acetabular necrosis and hip joint dislocation in HIV-positive patients is rare.MethodsWe report a 50-year-old man with a 15-month history of progressively worsening right hip pain with movement restriction. According to the CT findings of the other hospital, the patient was admitted to the hospital with femoral head necrosis. After the admission, the relevant X-ray, CT and MRI examinations showed that the right femoral head collapsed and deformed, with the surrounding bone sclerosis, bone fragments, loose body of the joint, right hip subluxation, acetabular marginal osteogeny, and local microcystic degeneration. The left femoral head was in good shape, and cystic degeneration can be seen under the articular surface. The patient was finally diagnosed with femoral head necrosis and acetabular necrosis combined with hip subluxation.ResultsThe pain of the patient was significantly relieved after the operation, and the patient was discharged from the hospital one week after the start of treatment to continue rehabilitation training. During the follow-up one month after the operation, the self-reported pain disappeared completely, and the limitation of activity was significantly improved.

Exploring diseases burden in HIV population: Results from the CHAO (Comorbidities in HIV/AIDS outpatients) cross-sectional study in Kenya

BackgroundAfrica is the epicenter of the HIV epidemic, with over two-thirds of the global population living with HIV. It is also facing a dramatic increase in non-communicable diseases (NCDs) amidst its aging population. This necessitates a healthcare approach that addresses both infectious diseases and NCDs in HIV-positive individuals. In Kenya, with 1.4 million HIV-positive people, efforts include widespread ART access and integrating HIV services into the health system. Challenges remain in healthcare infrastructure, particularly in rural areas. The Comorbidities in HIV/AIDS Outpatients (CHAO) Project, funded by the Italian Cooperation Agency, aims to improve understanding and management of comorbidities in HIV patients, highlighting the need for cost-effective healthcare strategies to address this dual burden. MethodsThe CHAO (Comorbidities in HIV/AIDS Outpatients) project conducted a cross-sectional epidemiological study across 25 clinics in Meru County, Kenya. The study included comprehensive surveys and screenings for various comorbidities among HIV-positive patients receiving treatment, utilizing both clinical evaluations and laboratory tests to assess the prevalence of infectious diseases and NCDs. ResultsA total of 1051 HIV-positive individuals were included in the study: 75 % females, 25 % males, median age 47 years, the majority (96 %) on long-term ART, mostly Dolutegravir-based (95 %). 55.4 % had at least one comorbidity, with NCDs such as dyslipidemia (21.22 %) and hypertension (20.17 %) being the most prevalent. The study also noted significant occurrences of communicable diseases, including syphilis (5.23 %), hepatitis B (2.19 %), and hepatitis C (0.29 %). The prevalence of comorbidities varied with age, highlighting the impact of aging on disease burden. DiscussionThe high prevalence of comorbidities among HIV-positive patients in Meru County underscores the need for integrated healthcare strategies that address both infectious diseases and NCDs. The findings advocate for systematic screening and management of comorbidities within HIV care programs, emphasizing the need for holistic health approaches to improve outcomes for this population.

Timing of recurrence after treatment of pulmonary TB

Pulmonary TB (PTB) may recur due to reinfection or relapse after initial successful treatment. Based on microbiologically documented cases, we searched Embase, PubMed, Web of Science, and Medline for PTB recurrence. The timeframe of overall recurrences, relapse, reinfection, and risk factors were assessed. We compared the time to recurrence, relapse, and reinfection from treatment completion and plotted this using Kaplan–Meier curves. This systematic review included 23 articles describing 2,153 PTB recurrences in 75,224 treated people across all continents. Genotyping data to distinguish relapse from reinfection was available for 402 recurrences. The cumulative recurrence percentage was 2.9% over 5 years, and the median time for recurrence was 18 months (95% CI 16.99–19.0). Most recurrences (93%) were in HIV-negative people. Relapse occurred earlier than reinfection at 12 months (95% CI 10.86–13.14) vs 24 months (95% CI 21.61–26.39) (P &lt; 0.001, χ2 59.89). In low TB burden settings, recurrences were mainly caused by relapse (85%), whereas in high-burden settings, relapses comprised 56% of recurrences. Recurrences occurred slightly earlier in HIV-positive patients (P = 0.038, χ2 4.30). The emergence of resistance to one or more first-line anti-TB agents was documented in 40 of 421 cases (9.5%). Early recurrences are mainly relapses, while late recurrences are mainly reinfections.

ENT manifestations and surgical interventions in patients with HIV

Background. Human Immunodeficiency Virus (HIV) infection represents a significant global health challenge, being one of the most interesting areas of current medicine regarding immunosuppression. Objective. The purpose of this study is to clinically evaluate the ear, nose, and throat (ENT) manifestations in HIV-positive patients and to determine the outcomes after surgical treatment of these manifestations. Methods. The clinical study sample included 223 HIV-positive patients from several hospitals in Romania, collected between 2018 and 2022, who presented with ENT complications and were treated for the remission of these manifestations. Results. The most common ENT complications diagnosed in HIV patients include persistent oral candidiasis, laterocervical adenopathies, acute tonsillitis, acute and chronic rhinosinusitis, otomycosis, and acute suppurative otitis media. Conclusion. HIV-positive patients require regular follow-up by an otorhinolaryngologist. Surgical interventions for immunosuppressed patients necessitate a multidisciplinary approach.

Spontaneous intraspinal and intracranial subdural hematoma in a highly active antiretroviral therapy-naïve-patient with HIV

Spontaneous intraspinal and intracranial subdural hematomas (SDHs) are rare, potentially life-threatening complications. We present the case of a 38-yearold highly active antiretroviral therapy-naïve human immunodeficiency virus (HIV)- positive patient who developed simultaneous intraspinal and intracranial SDHs without hemostatic abnormalities. The patient presented with acute lower limb weakness and back pain, and later developed neurological symptoms, including diplopia and incontinence. This case highlights the importance of considering SDHs in HIV-positive patients presenting with neurological symptoms, and underscores the need for prompt diagnosis and multidisciplinary management.

Insights into the molecular network characteristics of major HIV-1 subtypes in developed Eastern China: a study based on comprehensive molecular surveillance data.

This study aimed to conduct a comprehensive molecular epidemiology study of major HIV-1 subtypes in developed Eastern China (Zhejiang Province). Plasma samples and epidemiological information were collected from 4180 newly diagnosed HIV-1 positive patients in Zhejiang Province in 2021. Pol sequences were obtained to determine the subtypes via multiple analytical tools. HIV-1 molecular networks were constructed on the basis of genetic distances to analyze transmission patterns among major subtypes. Furthermore, the birth-death skyline (BDSKY) model was utilized to estimate the transmission risks associated with large clusters (LCs). In 4180 patients, 3699 (88.49%) pol sequences were successfully obtained and classified into four subtype groups. In the networks under an optimal genetic distance of 0.01 substitutions/site, the majority of links (74.52%, 1383/1856) involved individuals within the same city, highlighting the predominant role of local transmission in driving the HIV-1 epidemic. In the CRF07_BC, CRF01_AE, and others/URFs networks, men who have sex with men (MSM) were the primary sexual transmission population, with the younger MSM group (< 30 years old) exhibiting higher linkage frequencies. Within the CRF08_BC network, 93.98% of individuals were infected primarily through heterosexual contact and had a significantly greater risk of localized clustering than other subtypes did. Moreover, fifteen identified LCs were predominantly transmitted through commercial heterosexual contact (CHC), exhibiting localized clustering and high potential for sustained diffusion. Overall, our findings reveal a diverse and heterogeneous distribution of HIV-1 subtypes in Zhejiang Province, with noticeable variations in hotspots across different geographic areas and populations.

Bilateral tuberculosis psoas abscess in a human immunodeficiency virus-positive patient: a case report

BackgroundWorldwide, there is an increase in the frequency of reports of psoas abscesses due to advances in imaging technology, which has led to early diagnosis and treatment. A bilateral psoas abscess is rare and, when it occurs, is usually secondary and in immunocompromised patients. We present a case of a bilateral tuberculosis psoas abscess in a human immunodeficiency virus-positive patient.Case presentationA 21-year-old Ugandan female undergraduate who contracted human immunodeficiency virus through vertical transmission and has been on highly active antiretroviral drugs presented with bilateral lower abdominal pain with associated fever and headache. Clinical examination revealed abdominal tenderness in both iliac fossae with palpable masses. Ultrasonography revealed fluid collection in both psoas muscles confirming bilateral abscesses. The aspirate was acid-fast bacilli positive. A diagnosis of bilateral tuberculosis psoas abscess was made. Open drainage was performed and antituberculosis drugs were commenced.ConclusionsBilateral tuberculosis psoas abscesses occurring in human immunodeficiency virus-positive patients, although uncommon, is not unexpected. It is a form of secondary psoas abscess in immunocompromised patients. Here, the outcome was successful with a combination of early surgical drainage and appropriate medical therapy.

Evaluation of the use of additional capabilities of immunochemiluminescent analysis for determining the duration of infection with human immunodeficiency virus

Early assessment of HIV incidence is an important public health tool for understanding the state of the epidemic in a particular area, identifying high-risk groups, and assessing the effectiveness of HIV prevention interventions.Objective. To assess the possibility of using the positivity rate (S/CO) in the HIV Ag/Ab immunoassay on the Alinity i analytical platform to determine the duration of infection during HIV screening.Materials and methods. The study included 316 HIV-infected patients with different infection durations. Immunochemical analysis was performed on an Alinity i automatic analyzer (Abbott Laboratories, USA) using the Alinity i HIV Ag/Ab Reagent Kit (Abbott Laboratories, Germany) in accordance with the manufacturer’s instructions.Results. Statistical analysis of 316 blood samples from HIV-infected patients at different stages of infection demonstrated the reactivity of the Alinity i HIV Ag/Ab test result and a dynamic increase in the positivity ratio during the first six months after the onset of the disease. Based on the data obtained, a threshold value (≤294 conventional units) was obtained for the positivity ratio, which allowed for a clear distinction between HIV-positive patients with a recent (&lt;6 months) period of infection. At the same time, the sensitivity and specificity indicators for detecting recent infection in the CMIA analysis were 79,0% and 63,2%, respectively.Conclusion. The additional usage of the positivity ratio in the Alinity i HIV Ag/Ab CMIA analysis meets the acceptability criteria for assessing the duration of HIV infection and can be a useful tool for analyzing the stage of the epidemic in a particular territory.

Photogallery. HIV infection and neoplastic skin diseases

Malignant neoplasms constitute a group of the most important secondary diseases that develop in people infected with the human immunodeficiency virus (HIV). The first neoplastic disease described in HIV-infected patients is Kaposi's sarcoma. In contrast to other types of Kaposi's sarcoma, its epidemic (AIDS-associated) type is more common in young and middle-aged HIV-positive individuals, especially among men who have same-sex sex. Epidemic Kaposi's sarcoma does not have a favourite localisation. However, there is a tendency to lesions of the scalp (face, ear flaps), upper extremities, anogenital area, oral mucosa. On the trunk, the pathological process spreads along the Langer lines. Skin rashes are represented by spotty, papular, nodular elements of red-brown or purple colour. The aggressive course is characteristic: rapid dissemination and generalisation of rashes. Plasmoblastic lymphoma is associated with immunodeficiency states and is rare. The tumour lesion is usually located in the oral cavity. Few cases of plasmoblastic lymphoma with skin and soft tissue involvement have been described in the literature. Squamous cell skin cancer in the context of HIV infection is a dangerous disease. In people living with HIV, it manifests at a significantly earlier age and is associated with a high risk of local recurrence. The extent of invasion and the likelihood of metastasis are influenced by HIV-associated immunodeficiency. In the vast majority of cases, risk factors and clinical manifestations of basal cell skin cancer do not differ from those in immunocompetent individuals. Basal cell carcinomas rarely metastasise. Nevertheless, metastatic forms lead to unfavourable outcome. Here is a photo gallery of cases of neoplastic skin lesions developed in HIV-positive patients.

ОСОБЕННОСТИ КЛИНИЧЕСКОЙ КАРТИНЫ ОСТРОГО ПЕРИТОНИТА У ПАЦИЕНТОВ С ВИЧ-ИНФЕКЦИЕЙ

Background. The clinical picture of acute peritonitis in HIV-positive patients has its own specific features and is characterized by a blurred and multifaceted character, which significantly complicates the diagnosis of this disease. Purpose. To identify the features and specifics of the clinical picture of acute peritonitis in patients with HIV infection. Materials and methods. An analysis of the literature data was carried out, based on the outcome of which three syndromes were selected, which maximally included the known symptoms of acute peritonitis: abdominal pain syndrome, intestinal insufficiency syndrome and systemic inflammatory response syndrome (SIRS). The study included 158 patients with HIV infection who had a preliminary diagnosis of acute peritonitis. All patients underwent diagnostic laparoscopy, according to the results of which they were divided into the main and control groups. In the main group, 83 patients with a confirmed diagnosis of acute peritonitis were selected . The control group included 75 patients whose diagnosis of acute peritonitis was not confirmed. The analysis of the symptoms of acute peritonitis in HIV-infected patients was carried out within the framework of individual syndromes and their combination. Results. In the main group, abdominal pain syndrome was found in 20.5% of the patients, intestinal insufficiency syndrome was detected in 59%, and SIRS — in 61.4%. The following results were obtained in the control group: abdominal pain syndrome — 14.7% of the patients, intestinal insufficiency syndrome — 48%, SIRS — 33.3%. The study shows that a combination of “classic” criteria for acute peritonitis occurs in a small number of HIV-infected patients with acute peritonitis and is not always an absolute sign of the diagnosis. It was also noted that the presence of acute peritonitis in patients with HIV infection is possible even in the absence of all the “classic” criteria for this disease. Conclusion. The clinical picture of acute peritonitis in HIV-infected patients is atypical, characterized by mild or no “classic” symptoms, masked by the manifestation of opportunistic infections and HIV-indicative diseases, and requires further study to improve diagnosis and treatment.

Mitigating the Impact of HIV on Organ Function: Blood Transfusions as a Therapeutic Strategy

HIV (Human Immunodeficiency Virus) significantly impacts organ function, leading to various complications that can adversely affect the health and quality of life of individuals living with the virus. This review explores the multifaceted effects of HIV on organ systems, including the cardiovascular, renal, hepatic, and pulmonary functions, and highlights the potential of blood transfusions as a therapeutic strategy to mitigate these adverse effects. Blood transfusions can effectively address anemia—a common complication in HIV-positive individuals—enhancing oxygen delivery to tissues and improving overall organ function. Additionally, blood transfusions may exert immune-modulating effects, contributing to improved immune responses and potentially reducing the risk of opportunistic infections. This review discusses clinical evidence supporting the benefits of blood transfusions in enhancing organ function and quality of life among HIV-positive patients. Furthermore, it addresses the challenges and considerations associated with transfusion therapy, emphasizing the importance of individualized patient assessments and coordinated care strategies. Keywords: anemia, blood transfusions, HIV, immune response, organ function

Improved Wound Healing: The Healing Power of Blood Transfusions for Individuals with HIV

Wound healing in individuals with HIV is often compromised due to impaired immune function, chronic inflammation, and common comorbidities like anemia. Blood transfusions, traditionally used to manage anemia, have shown promise in enhancing wound healing through multiple mechanisms. This review explores the role of blood transfusions in improving wound healing for HIV-positive patients, focusing on their impact on oxygen delivery, immune modulation, inflammation reduction, and tissue repair. By restoring adequate hemoglobin levels, blood transfusions can improve oxygenation, support cellular metabolism, and promote collagen synthesis and angiogenesis, all crucial for effective wound healing. In addition to addressing anemia, blood transfusions may offer broader benefits, including the modulation of immune responses and the reduction of systemic inflammation. These effects can create a more favorable environment for wound healing, helping to mitigate prolonged inflammation and tissue damage commonly seen in HIV-positive individuals. Clinical studies and case reports have highlighted significant improvements in wound healing outcomes following transfusion therapy, underscoring its potential as a complementary intervention in HIV care. Keywords: anemia, blood transfusions, HIV, immune response, wound healing,

Helicobacter pylori infection and associated risk factors among HIV-positive and HIV-negative individuals in Northern Ethiopia

BackgroundH. pylori infection is a common bacterial infection worldwide, but its prevalence varies widely between different regions and populations. The objective of this study was to determine the prevalence of H. pylori infection and associated risk factors among HIV-positive and HIV-negative individuals in northern Ethiopia. MethodsA cross-sectional study was conducted from June to September 2020 in four randomly selected health facilities located in the Tigray region of Ethiopia. A total of 463 study participants were enrolled, of whom 288 were HIV-positive and 175 were HIV-negative individuals. H. pylori stool antigen tests were performed to detect H. pylori infection. Additionally, CD4+ T cell counts were measured from only a certain number of participants. ResultsThe overall prevalence of H. pylori infection among enrolled study participants was 39.7 %. Notably, the H. pylori infection rate was significantly higher in HIV-positive patients (43.4 %) compared to HIV-negative individuals (33.7 %); χ2 = 4.27, p = 0.039. Higher H. pylori prevalence was observed in participants with higher CD4+ T cell counts in both HIV-positive and HIV-negative individuals. Khat chewing habit, education, and monthly income levels were significantly associated with H. pylori infection in HIV-negative individuals, while the association between Body mass index (BMI) and H. pylori infection was observed in HIV-positive patients, but not HIV-negative individuals. ConclusionThis study demonstrates a higher prevalence of H. pylori infection in HIV-positive patients compared to HIV-negative individuals, emphasizing the importance of comprehensive diagnostics, patient care, and management of H. pylori infection in HIV-positive individuals.

Multidrug-Resistant Bacteria in Immunocompromised Patients.

The increasing incidence of antibiotic resistance in bacteria is a major problem in terms of therapeutic options, especially in immunocompromised patients, such as patients from intensive care units (ICUs), HIV-positive patients, patients with malignancies or transplant patients. Commensal bacteria, especially anaerobes, serve to maintain microbial stability by preventing overpopulation with pathogenic bacteria. In immunocompromised patients, microbiota imbalance caused by antibiotic therapy and decreased host immunity favors intestinal overpopulation with pathogenic species, leading to increased bacterial translocation and susceptibility to systemic infections. Infections with multidrug-resistant (MDR) bacteria pose major challenges to the establishment of appropriate treatment and lead to increased mortality. Asymptomatic colonization with MDR bacteria usually precedes infection and tends to persist for long periods of time, and in immunocompromised patients, colonization with MDR bacteria is a risk factor for systemic infections. This review aims to assess the relation between colonization and infection with MDR bacteria in immunocompromised patients such as ICU patients, HIV-positive patients and cancer patients and to identify the prevalence and patterns of MDR bacterial colonization and infection in this category of patients.

Poor Adherence and Limited Treatment Support are Risk Factors for Second Line Treatment Failure among HIV Children Under 15 Years, 2022: A Case Control Study

Title: Poor adherence and limited treatment support are risk factors associated with second line treatment failure among children under 15 years at Victoria Chitepo provincial hospital, 2022: a case control study. Background: New HIV resistance mutations have been emerging and frequently changing. HIV positive people switching to third line have been increasing in Manicaland Province. Third line anti-retroviral therapy (ART) combinations are not always available. We sort to determine the factors associated with second line treatment failure among HIV positive patients. Methods: We conducted a 1:1 unmatched case-control study among 107 case-control pairs. A case was any HIV positive individual with treatment failure confirmed by 2 viral load of ≥1000 copies/ml while a control was any HIV positive individual with a viral load of &lt;1000/ml copies; on second line therapy at Victoria Chitepo Provincial Hospital (VCPH), in 2022. Systematic random sampling was used to select cases and controls from the line-list. Administered questionnaires were used to ascertain risk factors to second line treatment failure. Patient booklets were reviewed for demographic and clinical characteristics. Frequencies, means, medians and odds ratios were generated. Multivariate analysis and stratified analysis was performed to identify independent risk factors. Permission to proceed was sought from relevant authorities and all ethical considerations were observed. Results: Defaulting treatment (aOR=2.42, 95% CI: 1.03-5.93), missing a viral load test (aOR=5.52, 95% CI: 2.30-13.26) and being under 15 years of age (aOR=6.18, 95% CI: 1.46-26.20) were independent risk factors associated with second line treatment failure. Having a treatment support was an independent protective factor (aOR=0.30, 95% CI: 0.10-0.86). Conclusion: Poor adherence is the key drive to second line treatment failure. Good adherence is critical in children under 15 years. Treatment support promotes viral load suppression.
