Individuals affected by human immunodeficiency virus (HIV) have a growing demand for coronary artery bypass grafting (CABG) due to heightened risk for cardiovascular diseases and extended life expectancy. However, CABG outcomes in HIV patients are not well-established, with insights only from small case series studies. This study conducted a comprehensive, population-based examination of in-hospital CABG outcomes in HIV patients. Patients underwent CABG were identified in National Inpatient Sample from Q4 2015-2020. Patients with age < 18 years and concomitant procedures were excluded. A 1:5 propensity-score matching was used to address preoperative group differences. Among patients who underwent CABG, 613 (0.36%) had HIV and were matched to 3119 out of 167,569 non-HIV patients. For selected HIV patients, CABG is relatively safe, presenting largely similar outcomes. After matching, HIV and non-HIV patients had comparable in-hospital mortality rates (2.13% vs. 1.67%, p = 0.40). Risk factors associated with mortality among HIV patients included previous CABG (aOR = 14.32, p = 0.01), chronic pulmonary disease (aOR = 8.24, p < 0.01), advanced renal failure (aOR = 7.49, p = 0.01), and peripheral vascular disease (aOR = 6.92, p = 0.01), which can be used for preoperative risk stratification. While HIV patients had higher acute kidney injury (AKI; 26.77% vs. 21.77%, p = 0.01) and infection (8.21% vs. 4.18%, p < 0.01), other complications were comparable between the groups.

PURPOSE: Obesity is rising among people with HIV (PLWH), sparking interest in bariatric surgery (BS) for this group. Yet, large-scale comparative research on BS outcomes in PLWH is lacking. METHODS: We performed a retrospective, matched cohort analysis in PLWH and HIV uninfected controls. Subjects were retrieved from the Dutch Audit for Treatment of Obesity (DATO) registry. Matching (1:7 ratio) included age (± 5-years), sex, body-mass index (BMI) of ± 3 kg/m2, surgery type, and associated health problems (AHPs) at baseline. The primary endpoint was total weight loss percentage (%TWL) ≥ 20% achieved at 1-year post-BS. Secondary endpoints were cumulative %TWL achieved at 2-years post-BS, a reported remission or improvement in AHPs post-BS, and surgical complications, both at 1-year post-BS. Comparisons were performed using conditional logistic regression. RESULTS: Twenty-seven PLWH and 168 controls were included. At 1-year post-BS, 89% PLWH achieved ≥ 20%TWL, compared to 94% of controls (p = 0.4). Cumulative %TWL at 2-years post-BS were 82% and 92% in PLWH and controls, respectively (p = 0.2). Improvement rates in hypertension and type 2 diabetes mellitus were 50% and 86% in PLWH, versus 87% and 87% in controls. Full remission occurred in 20% and 71% of PLHIV, versus 49% and 44% of controls, respectively. No improvement or remission was observed for dyslipidaemia in PLHIV compared to 54% improvement and 29% remission in controls. Surgical complications were 0% in PLHIV and 13% (n = 21) in controls. CONCLUSION: Efficacy and safety outcomes of BS were similar between PLWH and controls except for the lack of improvement in dyslipidaemia in PLWH.

BACKGROUND: Experience with lung transplantation (LT) in patients with human immunodeficiency virus (HIV) is limited. Many studies have demonstrated the success of kidney and liver transplantation in HIV-seropositive (HIV+) patients. Our objective was to conduct a national registry analysis comparing LT outcomes in HIV+ to HIV-seronegative (HIV-) recipients. METHODS: The United Network for Organ Sharing database was queried to identify LTs performed in adult HIV+ patients between 2016 and 2023. Patients with unknown HIV status, multiorgan transplants, and redo transplants were excluded. The primary endpoints were mortality and graft rejection. Survival time was analyzed using Kaplan-Meier analysis. RESULTS: The study included 17 487 patients, 67 of whom were HIV+. HIV+ recipients were younger (59 vs. 62 years, p = .02), had higher pulmonary arterial pressure (28 vs. 25 mm Hg, p = .04), and higher lung allocation scores (47 vs. 41, p = .01) relative to HIV- recipients. There were no differences in graft/recipient survival time between groups. HIV+ recipients had higher rates of post-transplant dialysis (18% vs. 8.4%, p = .01), but otherwise had similar post-transplant outcomes to HIV-recipients. CONCLUSIONS: This national registry analysis suggests LT outcomes in HIV+ patients are not inferior to outcomes in HIV- patients and that well-selected HIV+ recipients can achieve comparable patient and graft survival rates relative to HIV- recipients.

Toxoplasma gondii is a parasite that is estimated to infect one-third of the world's population. It is acquired by ingesting contaminated water and food specially undercooked meat, contact with domestic or wild feline feces, and during pregnancy by transplacental transmission.Immunocompetent hosts are usually asymptomatic, and infection will be self-limited, while those patients whose immune system is debilitated by HIV infection, immunosuppressive therapy, long-term steroid treatment, and fetuses infected during gestation will show evidence of systemic activity which is more severe in the central nervous system and eyes due to insufficient immune response caused by their respective blood barriers. Congenital toxoplasmosis has an estimated incidence of 8% in mothers who were seronegative at the beginning of their pregnancy. Infection in the first trimester may result in spontaneous abortion or stillbirth; however, it is estimated that the highest risk for vertical transmission is during the second and third trimesters when blood flow and placenta thickness favor parasitic transmission.Congenital toxoplasmosis can be detected with periodic surveillance in endemic areas, and with appropriate treatment, the risk of vertical transmission can be reduced, and the severity of the disease can be reversed in infected fetuses.While most infected newborns will show no evidence of the disease, those who suffer active intrauterine complications will present with cerebral calcifications in 8-12% of cases, hydrocephalus in 4-30%, and chorioretinitis in 12-15%. Also, seizure disorders, spasticity, and varying degrees of neurocognitive deficits can be found in 12%.Four distinct patterns of hydrocephalus have been described: aqueductal stenosis with lateral and third ventricle dilatation, periforaminal calcifications leading to foramen of Monro stenosis with associated asymmetrical ventricle dilatation, a mix of aqueductal and foramen of Monro stenosis, and overt hydrocephalus without clear evidence of obstruction with predominant dilatation of occipital horns (colpocephaly).While all patients diagnosed with congenital toxoplasmosis should undergo pharmacological treatment, those presenting with hydrocephalus have traditionally been managed with CSF shunting; however, there are reports of at least 50% success when selected cases are treated with endoscopic third ventriculostomy. Successful hydrocephalus management with appropriate treatment leads to better intellectual outcomes.

PURPOSE: The study aimed to investigate factors associated with in-hospital mortality in children diagnosed with tuberculous meningitis (TBM) hydrocephalus and HIV co-infection undergoing cerebrospinal fluid diversion procedures and their complications. METHODS: Data were collected retrospectively and prospectively between 2007 and 2022. Data collected included demographics, clinical characteristics, antiretroviral therapy (ART) status, biochemistry results, CD4 count, radiology findings, CSF diversion procedures (and complications), length of hospital stay (LOHS), and in-hospital mortality. RESULTS: Thirty-one children were included, with a mean age of 6.7 ± 5.3 years and 67.7% males. Median admission Glasgow Coma Scale (GCS) was 11 (IQR 9-15). Hypertonia (64.5%) and seizures (51.6%) were frequently observed clinical characteristics. Sixty-one percent of children were on ART. Cerebral infarcts and extra-meningeal TB were diagnosed in 64.5% and 19.3% of cases, respectively. The median CD4 count was 151 (IQR 70-732) cells/µL. Surgical procedures included ventriculoperitoneal shunt (VPS) in 26 cases and endoscopic third ventriculostomy (ETV) in five children. VPS complication rate was 27%. No complications were reported for ETV. Median LOHS was 7 days (IQR 4-21). Eleven children (35.5%) died during admission. Factors associated with mortality included GCS (p = 0.032), infarcts (p = 0.004), extra-meningeal TB (p = 0.003), VPS infection (p = 0.018), low CD4 count (p = 0.009), and hyponatremia (p = 0.002). No statistically significant factors were associated with VPS complications. CONCLUSION: TBM hydrocephalus in HIV-infected children carries a high mortality. Clinicians in high-prevalence settings should have a high suspicion index and institute early treatment.

BACKGROUND: Haemophilic arthropathy (HA) is a common comorbidity of haemophilia. Some people with haemophilia (PWH) were human immunodeficiency virus (HIV)-positive. Arthroplasty is an effective treatment for end-stage HA. This study was carried out to report the effectiveness and satisfaction following total hip arthroplasty (THA) or total knee arthroplasty (TKA) in PWH with HIV. PATIENTS AND METHODS: All patients with haemophilia and HIV undergoing THA or TKA in our centre from January 2015 to June 2020 were reviewed. All patients were followed for at least twenty-four months. The improvements in postoperative indicators were evaluated at the latest follow-up, including the Visual Analogue Scale (VAS) score, range of motion (ROM), and validated joint scores such as Knee Society Score (KSS; clinical and functional) and Harris Hip Score (HHS). The complications and satisfaction were analysed likewise. Those were utilized to weigh the risks and benefits of the procedure in the population. RESULTS: Fourteen patients (7 hips and 14 knees) were included in the study. The follow-up of the THA cohort was 53.3 months (range, 27-82) and the TKA cohort was 50.1 months (range, 25-85), respectively. The average VAS score was ameliorated from 7.3 to 3.0 and 6.6 to 2.8 in the two groups (P < .001, respectively). Similarly, two cohorts (THA and TKA) showed statistically significant changes in the extension and flexion ROM between the preoperative and the latest follow-up (P < .05, P < .001, respectively). Besides, statistically significant differences between the preoperative and final follow-up values of HHS (from 41.6 to 82.3), clinical KSS (from 34.8 to 72.8), and functional KSS (from 42.9 to 73.2) were observed (P < .001, respectively). Notably, there were 4 complications noted among 21 arthroplasties performed, giving a 19.0% complication rate. Based on the satisfaction score, the majority of patients were optimistic about the arthroplasty. CONCLUSION: Given these findings, THA or TKA of the PWH with HIV is a worthwhile procedure and can be performed by an experienced and collaborative multidisciplinary team in a tertiary centre with a good haemophilia care system.

We report a case of a patient who developed several urological comorbidities associated with HIV infection. A 53-year-old male was diagnosed with HIV infection and AIDS. After 13 years, microhematuria was found and computed tomography (CT) revealed urolithiasis and a left renal tumor suspected of being renal cell carcinoma. Initially, he underwent transurethral lithotripsy. Stone analysis indicated that the stone was made of atazanavir. Then he received laparoscopic left partial nephrectomy. The pathological diagnosis was papillary type 2 renal cell carcinoma. Three years later, follow-up CT revealed a right renal pelvic tumor. Since right ureteroscopy showed that the tumor was papillary we diagnosed it as renal pelvic cancer and decided to perform laparoscopic right radical nephroureterectomy. His renal pelvic tumor was determined to be urothelial carcinoma by the pathological diagnosis. Intravesical recurrence occurred twice after the nephroureterectomy. His renal function gradually deteriorated during follow-up and we suspected that HIV nephrosis was one of the reasons for the deterioration. Hemodialysis was initiated at the age of 71.

ABSTRACT: Many patients are affected by HIV/AIDS, and these conditions are highly prevalent worldwide. Patients with HIV/AIDS can experience debilitating wound infections that often require flap reconstruction and become challenging for surgeons to treat. In the past 5 years, mesenchymal stem cells have been tested and used as regenerative therapy to promote the growth of tissues throughout the body because of their ability to successfully promote cellular mitogenesis. To the authors' knowledge, the use of mesenchymal stem cell grafting following necrosis of a myocutaneous gracilis flap (as part of perineal wound reconstruction) has never been reported in the literature.In addition, the use of mesenchymal stem cells and regenerative medicine combined in the setting of squamous cell carcinoma of the anus with prior radiation (along with comorbid AIDS) has not been previously documented.In this report, the authors outline the case of a 60-year-old patient who had a recipient bed (perineum) complication from prior radiation therapy. Complicating the clinical picture, the patient also developed a Pseudomonal organ space infection of the pelvis leading to the failure of a vertical rectus abdominis myocutaneous flap and myocutaneous gracilis flaps. As a result, the patient underwent serial operative debridements for source control, with the application of mesenchymal stem cells, fetal bovine dermis, porcine urinary bladder xenograft, and other regenerative medicine products, achieving a highly successful clinical outcome. A procedural description for future use and replication of this method is provided.

Background: Studies have reported that osteonecrosis of the femoral head (ONFH) is more prevalent in patients with human immunodeficiency virus (HIV). Total hip arthroplasty (THA) is considered reasonable management of ONFH. However, only scarce data exist on the outcomes of THA for HIV-infected patients in South Korea. The purpose of this study was to evaluate the midterm results of HIV-positive patients who underwent THA for ONFH. Methods: We performed a retrospective review of HIV-infected patients with ONFH who underwent THA in our institution from 2005 to 2021. Twenty-two hips in 15 patients underwent THAs with cementless implants. The clinical and radiographic evaluation was performed at each follow-up, and any complication was recorded. Results: The mean follow-up period was 5.2 years (range, 1.0-16.0 years). The mean age of the HIV infected patients with osteonecrosis at the time of surgery was 44.7 ± 11.6 years. ONFH occurred 9.8 ± 3.7 years after the initial diagnosis of HIV infection. The average modified Harris hip score improved from 58.3 ± 14.8 to 95.2 ± 11.3 at the latest follow-up. Surgical complications such as infection, nerve injury, or dislocation were not present. The radiographic evidence of stable fixation by bone ingrowth without migration was seen in all implants. Conclusions: Our data suggest that THA is a safe and valid option of treatment for ONFH in well-controlled HIV-infected patients in Korea. Further large-scale nationwide studies are warranted.

INTRODUCTION: We aimed to characterize the clinicopathological characteristics and outcomes of HIV-positive patients with clinically localized, prostate cancer (PCa). METHODS: A retrospective study was conducted of HIV-positive patients from a single institution with elevated PSA and diagnosis of PCa by biopsy. PCa features, HIV characteristics, treatment type, toxicities, and outcomes were analyzed by descriptive statistics. Kaplan-Meier analysis was used to determine progression-free survival (PFS). RESULTS: Seventy-nine HIV-positive patients were included with a median age at PCa diagnosis of 61 years-old and median duration from HIV infection to PCa diagnosis of 21 years. The median PSA level at diagnosis and Gleason Score was 6.85 ng/mL and 7, respectively. The 5-year PFS was 82.5% with the lowest survival observed in patients treated with radical prostatectomy (RP) + radiation therapy (RT), followed by cryosurgery (CS). There were no reports of PCa-specific deaths, and the 5-year overall survival was 97.5%. CD4 count declined post-treatment in pooled treatment groups that included RT (P = .02). CONCLUSION: We present the characteristics and outcomes of the largest cohort of HIV-positive men with prostate cancer in published literature. RP and RT ± ADT is well-tolerated in HIV-positive patients with PCa as seen by the adequate biochemical control and mild toxicity. CS resulted in worse PFS compared to alternative treatments for patients within the same PCa risk group. A decline in CD4 counts was observed in patients treated RT, and further studies are needed to investigate this relationship. Our findings support the use of standard-of-care treatment for localized PCa in HIV-positive patients.

PURPOSE: End-stage knee arthropathy is a recognised complication of haemophilia. It is often treated by total knee arthroplasty (TKA), which is more technically challenging in patients with haemophilia (PwH). It remains unclear what factors may predict implant survivorship and deep infection rate. Therefore, we systematically review the evidence regarding TKA survivorship and infection in PwH, compared to the general population, and determine the important factors influencing survivorship, particularly HIV and CD4 + count. METHODS: A systematic literature review was conducted using MEDLINE, EMBASE, and PubMed for studies reporting Kaplan-Meier survivorship for TKA in PwH (PROSPERO CRD42021284644). Meta-analysis was performed for survivorship, and the results compared to < 55-year-olds from the National Joint Registry (NJR). Meta-regression was performed to determine the impact of relevant variables on 10-year survivorship, with a sub-analysis focusing on HIV. RESULTS: Twenty-one studies were reviewed, totalling 1338 TKAs (average age 39 years). Implant survivorship for PwH at 5, 10, and 15 years was 94%, 86%, and 76% respectively. NJR-reported survivorship for males < 55 years was 94%, 90%, and 86%. Survivorship improved over time (1973-2018), and correlated inversely with HIV prevalence. Infection rate was 5%, compared to 0.5-1% in the NJR. Infection was not significantly increased with higher HIV prevalence, and CD4 + count had no effect. Complications were inconsistently reported. CONCLUSION: Survivorship was similar at 5 years but declined thereafter, and infection rate was six-fold higher. HIV was related to worse survivorship, but not increased infection. Meta-analysis was limited by inconsistent reporting, and standardised reporting is required in future studies.

INTRODUCTION: Patients with HIV infection have increased risk of atrial fibrillation, but the pathophysiologic mechanisms and the utility of catheter ablation in this population are not well-studied. We aimed to characterize outcomes of atrial fibrillation ablation and left atrial substrate in patients with HIV. METHODS: The study was a retrospective propensity score-matched analysis of patients with and without HIV undergoing atrial fibrillation ablation. A search was performed in the electronic medical record for all patients with HIV who received initial atrial fibrillation ablation from 2011 to 2020. After calculating propensity scores for HIV, matching was performed with patients without HIV by using nearest-neighbor matching without replacement in a 1:2 ratio. The primary outcome was freedom from atrial arrhythmia and secondary outcomes were freedom from atrial fibrillation, freedom from atrial tachycardia, and freedom from repeat ablation, compared by log-rank analysis. The procedures of patients with HIV who underwent repeat ablation at our institution were further analyzed for etiology of recurrence. To further characterize the left atrial substrate, a subsequent case-control analysis was then performed for a set of randomly chosen 10 patients with HIV matched with 10 without HIV to compare minimum and maximum voltage at nine pre-specified regions of the left atrium. RESULTS: Twenty-seven patients with HIV were identified. All were prescribed antiretroviral therapy at time of ablation. These patients were matched with 54 patients without HIV by propensity score. 86.4% of patients with HIV and 76.9% of controls were free of atrial fibrillation or atrial tachycardia at 1 year (p = .509). Log-rank analysis showed no difference in freedom from atrial arrhythmia (p value .971), atrial fibrillation (p-value .346), atrial tachycardia (p value .306), or repeat ablation (p value .401) after initial atrial fibrillation ablation in patients with HIV compared to patients without HIV. In patients with HIV with recurrent atrial fibrillation, the majority had pulmonary vein reconnection (67%). There were no significant differences in minimum or maximum voltage at any of the nine left atrial regions between the matched patients with and without HIV. CONCLUSIONS: Ablation to treat atrial fibrillation in patients with HIV, but without overt AIDS is frequently successful therapy. The majority of patients with recurrence of atrial fibrillation had pulmonary vein reconnection, suggesting infrequent nonpulmonary vein substrate. In this population, the left atrial voltage in patients with HIV is similar to that of patients without HIV. These findings suggest that the pulmonary veins remain a critical component to the initiation and maintenance of atrial fibrillation in patients with HIV.

BACKGROUND: Femoral head osteonecrosis (FHON) is a well-recognised complication in patients with human immunodeficiency virus (HIV) infection. Total hip arthroplasty (THA) is a reliable solution to FHON and has provided functional improvement and pain relief in these patients. Higher complication rates, in particular infections, have been reported in the series of THAs done in the HIV-positive patients. The purpose of this study was to evaluate the complication rate of THA for FHON in HIV-positive patients managed with the highly active antiretroviral therapy (HAART) protocols. METHODS: A retrospective review was performed of HIV-positive patients with FHON who underwent THAs over a 10-year period at a single institution. RESULTS: A total of 56 THAs (44 patients) met the inclusion criteria. The mean age at the time of THAs was 47 (range 34-60) years. Of the 44 patients, 39 (88.6%) were males. The mean follow-up was 6.6 (range 2.0-11.3) years. The overall complication rate was 12.5%, with 2 (3.6%) cases of deep periprosthetic infections. CONCLUSIONS: HIV-positive patients with FHON undergoing THAs do have a considerable complication rate (12.5%). The deep periprosthetic infection rate (3.6%) in these patients, however, has decreased with contemporary disease modification protocols.

BACKGROUND: Hydrocephalus and increased intracranial pressure secondary to human immunodeficiency virus-related cryptococcal meningitis are rare in children. The role and outcomes of cerebrospinal fluid (CSF) shunting in children are not well reported. We report our experience with CSF shunting in the management of this condition in children over a 14-year period. METHODS: This was a retrospective review of data collected from a single neurosurgery unit. Data collected included demographics, clinical characteristics, Glasgow Coma Scale score, lumbar puncture opening pressure, antiretroviral therapy, laboratory results, neuroimaging findings, shunting procedures, complications, and mortality. RESULTS: Seventeen children underwent CSF shunting. Median age was 10 years (range, 6-13), most being male (76%). All children were on antiretroviral therapy. Median Glasgow Coma Scale score was 15 (interquartile range [IQR], 14-15). Clinical characteristics included headaches (100%), visual impairment (82%), and seizures (47%). Lumbar puncture opening pressure was >30 cm H2O in 88% of children. Median CD4 count was 45 cells/µL (IQR, 17-56). Computed tomography brain scans showed hydrocephalus in 14 children (82%). Surgical procedures included ventriculoperitoneal shunts (82%) and lumboperitoneal shunts (18%). Shunt complications included infection (18%) and obstruction (18%). Staphylococcus aureus was cultured in all infections. Median follow-up was 45 months (IQR, 7.5-74). Three children (18%) died during the admission period. Ten children (59%) were alive at 1 year follow-up. CONCLUSIONS: This study is the largest series reporting on CSF shunting of hydrocephalus and increased intracranial pressure in children with human immunodeficiency virus-related cryptococcal meningitis. Treatment with ventriculoperitoneal shunt and lumboperitoneal shunt regardless of the CD4 count is an important option in suitable children to reduce mortality.

PURPOSE: Human immunodeficiency virus (HIV)-related mortality has decreased secondary to advances in antiretroviral therapy (ART), and the incidence of obesity in this population is increasing. Bariatric surgery is an effective method of weight loss, though changes in the gastrointestinal tract may affect ART absorption and virologic suppression. Existing data are limited to case reports studying outdated therapeutic regimens; studies evaluating modern ART regimens are needed. The objective of this study was to determine if undergoing bariatric surgery impacts HIV virologic failure rate at 12 months post-surgery and to characterize the failure population. MATERIALS AND METHODS: This retrospective case series included adults with virologically suppressed HIV on ART who underwent roux-en-y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgery between 2000 and 2019 (n=20) at one of three medical centers within one academic medical system. The primary outcome was proportion of patients with ART failure at 12 months post-surgery. Select additional data collected included CD4+ count, metabolic parameters, postoperative complications, and medication non-adherence. RESULTS: A total of 18 patients were included in this analysis. Seventeen of 18 patients (94%) maintained virologic suppression within 12 months post-surgery. There were no significant changes in CD4+ counts before and after surgery. The one failure was an African American woman who underwent sleeve gastrectomy surgery. This patient's baseline viral load was undetectable and CD4+ count was 263 cells/mm3. CONCLUSION: Undergoing bariatric surgery did not increase virologic failure rate in a small cohort of persons living with HIV, and ART non-adherence was associated with virologic failure.

BACKGROUND: The objective of this study in MSM living with HIV was to determine the incidence of HSIL and ASCC, related factors, and the response to treatment. PATIENTS AND METHODS: Data were gathered in 405 consecutive HIV-infected MSM (May 2010-December 2018) at baseline and annually on: sexual behavior, anal cytology, and HPV PCR and/or high-resolution anoscopy results. They could choose mucosectomy with electric scalpel (from May 2010) or self-administration of 5% imiquimod 3 times weekly for 16 weeks (from November 2013). A multivariate logistic regression model was developed for ≥HSIL-related factors using a step-wise approach to select variables, with a significance level of 0.05 for entry and 0.10 for exit, applying the Hosmer-Lemeshow test to assess the goodness of fit. RESULTS: The study included 405 patients with a mean age of 36.2 years; 56.7% had bachelor´s degree, and 52.8% were smokers. They had a mean of 1 (IQR 1-7) sexual partner in the previous 12 months, median time since HIV diagnosis of 2 years, and mean CD4 nadir of 367.9 cells/uL; 86.7% were receiving ART, the mean CD4 level was 689.6 cells/uL, mean CD4/CD8 ratio was 0.77, and 85.9% of patients were undetectable. Incidence rates were 30.86/1,000 patient-years for ≥high squamous intraepithelial lesion (HSIL) and 81.22/100,000 for anal squamous cell carcinoma (ASCC). The ≥HSIL incidence significantly decreased from 42.9% (9/21) in 2010 to 4.1% (10/254) in 2018 (p = 0.034). ≥HSIL risk factors were infection with HPV 11 (OR 3.81; 95%CI 1.76-8.24), HPV 16 (OR 2.69, 95%CI 1.22-5.99), HPV 18 (OR 2.73, 95%CI 1.01-7.36), HPV 53 (OR 2.97, 95%CI 1.002-8.79); HPV 61 (OR 11.88, 95%CI 3.67-38.53); HPV 68 (OR 2.44, CI 95% 1.03-5.8); low CD4 nadir (OR1.002; 95%CI 1-1.004) and history of AIDS (OR 2.373, CI 95% 1.009-5.577). Among HSIL-positive patients, the response rate was higher after imiquimod than after surgical excision (96.7% vs 73.3%, p = 0.009) and there were fewer re-treatments (2.7% vs 23.4%, p = 0.02) and adverse events (2.7% vs 100%, p = 0.046); none developed ASCC. CONCLUSIONS: HSIL screening and treatment programs reduce the incidence of HSIL, which is related to chronic HPV infection and poor immunological status. Self-administration of 5% imiquimod as first-line treatment of HSIL is more effective than surgery in HIV+ MSM.

BACKGROUND: Vertebral pathological compression fracture involving extra-nodal lymphoma impacts negatively on the quality of life of HIV-positive patients. The choice of a safe and effective approach to palliative care in this condition remains a challenge. OBJECTIVE: The purpose of this study was to investigate the safety and efficacy of percutaneous kyphoplasty (PKP) in the treatment of vertebral pathological compression fracture of extra-nodal lymphoma in HIV-positive patients. METHODS: A retrospective analysis, from January 2016 to August 2019, was performed on 7 HIVpositive patients, 3 males and 4 females, with extra-nodal lymphoma with a vertebral pathological compression fracture. The patients were treated using percutaneous kyphoplasty in our hospital. Preoperative assessment of the patients was conducted regarding their hematological profile, biochemical indicators, liver and kidney function, blood coagulation function, CD4+T lymphocyte count and viral load. Subsequently, the patients were placed on highly active antiretroviral therapy (HAART) and rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP) regimen. Besides, antibiotics, nutritional support and immune-modulating drugs were also administered, rationally. Postoperatively, the height of the anterior edge of the injured vertebrae, Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) values were evaluated. Patients were also monitored for any complications related to the operation. RESULTS: The average CD4+T cell count for the patients was 164 (range 114 ~247 / ul), while the viral load was 26,269 (range 5,765 ~82,321 copies/ul). All patients received nutritional and immune support and registered significant improvements in the levels of ALB and Hb (P<0.05). In all cases, the operation was uneventful with neither cement leakage nor toxic reactions observed. Similarly, no opportunistic infections, other complications or deaths were reported. The height of the anterior vertebral body and the ODI score of the injured vertebrae were significantly improved immediately after surgery (P<0.05). Compared to the preoperative VAS (7.71±1.11), postoperative values were significantly reduced immediately after surgery (3.85±0.90) and at 2 weeks, 1 month and 6 months post-surgery: 2.71±0.76, 3.29±1.11, and 4.00±0.82, respectively (P<0.01). CONCLUSION: Supported with appropriate perioperative treatment measures, PKP is safe and effective in the treatment of pathological vertebral compression fracture due to extra-nodal lymphoma in HIV-positive patients.

Pre-Exposure Prophylaxis (PrEP) is an approach for preventing the human immunodeficiency virus (HIV), which entails the administration of antiretroviral medication to high-risk seronegative persons. If taken correctly, PrEP can reduce HIV infection risk by more than 90%. The aim of this study was to identify and examine PrEP-related perceptions and trends discussed on Twitter. Using open-source technologies, text-mining and interactive visualisation techniques, a comprehensive data gathering and analytics Web-based platform was developed to facilitate the study objectives. Our results demonstrate that monitoring of PrEP-related discussions on Twitter can be detected over time and valuable insights can be obtained concerning issues of PrEP awareness, expressed opinions, perceived barriers and key discussion points on its adoption. The proposed platform could support public-health professionals and policy makers in PrEP monitoring, facilitating informed decision making and strategy planning for efficient HIV combination prevention.

Lipo-accumulation of the dorsocervical fat pad ("buffalo hump") is a complication observed in people living with human immunodeficiency virus (HIV). We described the clinical outcome of people living with HIV with "buffalo hump" treated by excisional lipectomy.From April 2013 to March 2018, medical records of people living with HIV, who received care in our hospital have been evaluated. Among them, patients with dorsocervical fat accumulation treated by excisional lipectomy have been retrospectively assessed.Nine patients with "buffalo hump" among 2886 people living with HIV (3.1, 9/2886) were included. Eight were women with a mean age of 47.9â±â8.0 years old (range, 36-60). Most of them have been infected by blood transfusion (77%, 7/9) and the mean duration of HIV infection was 14.1â±â5.5 years (range, 6-22). The mean duration for antiretroviral therapy was 8.8â±â2.1 years (range, 6-11). The mean pre-ART CD4+ T cell count was 91.3â±â76.5âcells/µL (range, 4-233) and 477.4â±â271.8âcells/µL (range, 114-926) at the time of surgery. All 9 patients underwent excisional lipectomy of their hypertrophied dorsocervical fat pad. The mean size of the excised specimens was 14â×â11â×â6âcm. The median follow-up time was 24 months (range, 2-60), all 9 patients reported satisfaction with their results, with no recurrence has been observed.Corrective surgery used to treat localized fat accumulations in people living with HIV with "buffalo hump" showed a favorable effect and can therefore be considered when necessary. Whereas drugs such as integrase inhibitors may avoid lipo-accumulation related syndrome and should be given to people living with HIV in China.
