The urological management of the patient with acquired immunodeficiency syndrome

Multiorgan and Multisystem Involvement During Primary HIV Infection: A Case Report With a Literature Review

The initial six months following HIV infection have a high viral load. Nonspecific presentations might lead to the missing primary HIV diagnosis. Multiorgan and multisystem diagnosis is a rare presentation of primary HIV. A 40-year-old male patient with no documented comorbidities presented with bilateral flank pain. The onset of the pain was gradual, characterized as dull and aching, with radiation toward the groin. The patient also had severe pain in the left shoulder and left ankle region. Per-abdominal examination revealed bilateral flank tenderness, with the right side being more tender than the left. Swelling of the left shoulder and ankle was observed, accompanied by tenderness and a restricted range of motion. Contrast-enhanced computed tomography of the chest and abdomen revealed bilateral pyelonephritis multiple renal abscesses and liver abscesses. Left shoulder septic arthritis was also present. Pus culture and blood culture were positive for methicillin-sensitive Staphylococcus aureus. Antibiotics, according to the culture sensitivity, were given, and retroviral therapy was started from the antiretroviral clinic. Primary HIV infection can present with a variety of signs and symptoms. This case demonstrates that AIDS can affect any organ and mimic other disease processes. The initial clinical picture might be confused with individually occurring diseases; therefore, we should consider AIDS in patients presenting with multiorgan failure. Early initiation of empiric and then culture-specific antibiotics along with antiretroviral therapy helps in the rapid improvement of the patient and controls the high viremia. The infected patient also needs appropriate counseling on ways to avoid high-risk behavior, which may prevent transmission of HIV.

Difficulties in the Modeling of E. coli Spreading from Various Sources in a Coastal Marine Area

Coastal and transitional waters are often used as bathing waters. In many regions, such activities play an important economic role. According to the European Union Bathing Water Directive (2006/7/EC) (BWD) the concentration of Escherichia coli in bathing water exceeding 500 CFU·100 mL⁻¹ poses a high risk for bathers’ health. In order to safeguard public health, microbiological environmental monitoring is carried out, which has recently been supported or replaced by mathematical models detailing the spread of sanitary contamination. This study focuses on the problems and limitations that can be encountered in the process of constructing a mathematical model describing the spread of biological contamination by E. coli bacteria in coastal seawater. This and other studies point to the following problems occurring during the process of building and validating a model: the lack of data on loads of sanitary contamination (often connected with multiple sources of biological contamination inflow) makes the model more complex; E. coli concentrations higher than 250 CFU·100 mL⁻¹ (low hazard for health) are observed very rarely, and are associated with great uncertainty; the impossibility of predicting the time and intensity of precipitation as well as stronger winds and rougher sea, which may be a significant source of E. coli. However, there is universal agreement that such models will be useful in managing bathing water quality and protecting public health, especially during big failures of the wastewater network.

Transcriptomics analysis for the identification of potential age-related genes and cells associated with three major urogenital cancers

Age is one of the most important risk factors of the occurrence for tumor patients. The majority of patients with urogenital cancers are the elderly, whose clinical characteristics are greatly affected by age and ageing. Our study aimed to explore age-related genes, cells, and biological changes in three common urogenital cancers via integrative bioinformatics analysis. First, mRNA (count format) and clinical data for bladder cancer, prostate cancer and renal cell carcinoma were downloaded from the Cancer Genome Atlas (TCGA). Through the comparison of clinicopathological characteristics, genes expression and cells infiltration between the old group and the young group, it was found that the clinical characteristics, genes and cells in the tumor microenvironment of different ages were quite different. And 4 key cells, 14 hub genes and some potential pathways were identified and considered as important factors. More importantly, we analyzed the differential landscape of the genes and cells from different perspectives, and confirmed its importance. In conclusion, we identified genes and cell types associated with age-related changes in the tumour microenvironment in urogenital cancer patients. These genes and cell types may play a critical role in the age-associated differences in clinicopathological characteristics among urogenital cancers, thus providing a link between ageing and cancer occurrence. The findings of this study may pave the way for the development of age-tailored approaches to treat cancer and other age-related diseases.

Septic shock secondary to acute bacterial prostatitis in an HIV-positive male: a novel presentation

Acute bacterial prostatitis, an acute infection of the prostate gland, results in lower abdominal pain, flank pain, urinary symptoms and the potential for systemic symptoms like fever and shock. With a high mortality rate if left untreated, acute bacterial prostatitis becomes a true urological emergency, which if allowed to progress, may result in bacteremia, severe sepsis/septic shock and death. Diagnosis is mainly clinical with a detailed history and physical and laboratory evaluation to include a urinalysis. However, imaging may be necessary to exclude other pathology. We present the case of a 44-year-old male with a history of well-controlled HIV that used a prostate vibrator for 1-week prior to his presentation to the ED. He was subsequently diagnosed with septic shock secondary to acute bacterial prostatitis and required ICU management.

HIV and Men

INTRODUCTION

Since the initial description of HIV and AIDS, monumental efforts have been made both in the developed and developing countries to devise strategies and medications to control the disease. The advent of highly active antiretroviral therapy has now meant that the diagnosis of HIV is no longer a life-sentence and compliant patients with HIV can expect life expectancy similar to their noninfected peers. Consequently new challenges have arisen in the management of benign conditions.

AIM

To provide an overview of the key conditions and issues that HIV/AIDS patients may present with to an andrological service.

METHODS

Using PubMed, we screened the literature for studies on common andrological conditions specifically pertaining to HIV and AIDS.

MAIN OUTCOME MEASURES

The urological manifestations of HIV/AIDS in men have been summarized in an attempt to provide a useful guide for sexual health practitioners dealing with HIV-positive men.

RESULTS

As a result of advancements in pharmaceuticals, life expectancy of men infected with HIV has improved almost to that of the general population in developed countries. Therefore, clinicians are faced with non-life-threatening urological problems that affect the quality of life of men with HIV. The majority of these problems can be managed easily, by adapting a "patient-centered" approach, instead of "disease-centered" algorithms.

CONCLUSION

With improved survival and understanding, patients with HIV/AIDS can and do expect to enjoy a healthy sex life. With appropriate counseling around safe sex and careful management with consideration for disease-specific issues as well as the influence of medical therapy, patients can achieve a good quality of life.

HIV-associated renal and genitourinary comorbidities in Africa

With the recent massive scale-up of access to antiretroviral therapy (ART) in resource-limited countries, HIV has become a chronic disease with new challenges. There is mounting evidence of an increased burden of renal and genitourinary diseases among HIV-infected persons caused by direct HIV viral effects and/or indirectly through the development of opportunistic infections, ART medication-related toxicities, and other noncommunicable diseases (NCDs). We review the epidemiology of HIV-associated renal and urogenital diseases, including interactions with kidney-related NCDs such as hypertension, diabetes mellitus, and cardiovascular disease. We also examine the current evidence regarding the impact of HIV infection on the development of urogenital diseases. Highly advisable in sub-Saharan Africa are the establishment of renal disease registries, reviews of existing clinical practice including cost-effectiveness studies, and the adoption and use of HIV-related NCD management, with training for different cadres of health providers. Epidemiological research priorities include prospective studies to evaluate the true prevalence and spectrum of HIV-related renal disease and their progression. Simple diagnostics tools should be evaluated, including urinary dipsticks and point-of-care urea and creatinine tests to screen for kidney injury in primary care settings. Study of urological manifestations of HIV can help determine the extent of disease and outcomes. As patients live longer on ART, the burden of renal and genitourological complications of HIV and of ART can be expected to increase with a commensurate urgency in both discovery and evidence-based improvements in clinical management.

Renal and urologic disorders in antiretroviral-treated patients with HIV infection or AIDS: spectrum of cross-sectional imaging findings

In the aging human immunodeficiency virus (HIV)-infected population with improved immune function under antiretroviral treatment, many different opportunistic disorders may be encountered, along with rare presentations or complicated forms of common diseases. Renal and urologic abnormalities observed in the setting of HIV infection or acquired immunodeficiency syndrome are reviewed with their imaging appearances, including renal dysfunction, urolithiasis, urinary tract infections and related complications, genitourinary tuberculosis, vascular lesions, urogenital tumors, and bladder abnormalities, with emphasis on characterization. In HIV-positive patients, early cross-sectional imaging is warranted to detect uncommon disorders and complications, with the aim to preserve renal function.

Prevalence of nephrolithiasis in human immunodeficiency virus infected patients on the highly active antiretroviral therapy

BACKGROUND AND PURPOSE

Protease inhibitors, specifically indinavir, have historically been implicated as a cause of nephrolithiasis in the human immunodeficiency virus (HIV) infected patients. There is a paucity of data, however, on stone disease with nonindinavir etiologies since the introduction of highly active antiretroviral therapy (HAART). We sought to describe the prevalence of nephrolithiasis in the HIV population since the use of HAART.

PATIENTS AND METHODS

We retrospectively reviewed HIV-positive patients currently receiving HAART treatment in whom image proven kidney and/or ureteral urolithiasis developed, between 1998 and 2010. A detailed analysis of patients' current treatment, surgical intervention, and metabolic studies was performed.

RESULTS

A total of 436 HIV-positive patients were included and 46 (11%) patients had nephrolithiasis. Each patient included in this study was receiving nonindinavir-based antiretroviral therapy. There were 41 men of whom 36 were Caucasian. Eleven (24%) patients underwent 24-hour urine collections with 11 metabolic abnormalities identified. Stone analysis was available for seven patients (four calcium oxalate monohydrate, one cystine, one uric acid, and one atazanavir).

CONCLUSIONS

We report the largest series of nephrolithiasis in an HIV population since the introduction of HAART and highlight not only the similar prevalence of nephrolithiasis to the non-HIV population but also the lack of consistent comprehensive metabolic evaluations in HIV patients with recurrent nephrolithiasis.

Urologic aspects of HIV infection

Although lifespan has dramatically improved in the human immunodeficiency virus-positive (HIV+) population, HIV and its treatment continue to be a source of substantial morbidity in many organ systems, including the genitourinary tract. As the number of long-term survivors increases with advances in antiretroviral therapy, age-associated urologic symptoms are also becoming increasingly relevant considerations for people living with HIV. Primary care physicians have a major role to play in maintaining the genitourinary health of their HIV+ patients. This role is of great importance not just for the well-being of the individual patient but for the public health, as the genitourinary tract is a common vector for HIV transmission. In this article the authors review the management of the genitourinary system in patients with HIV infection. Particular consideration is given to urinary tract infections, lower urinary tract symptoms, renal insufficiency, sexual and fertility problems, and cancers of the genitourinary tract. Management algorithms are outlined and indications for referral to a urologist are emphasized.

Sexual dysfunctions among people living with AIDS in Brazil

INTRODUCTION

Sexual dysfunction symptoms in patients with HIV have not been fully investigated in Brazil.

OBJECTIVES

To investigate the association between sexual dysfunction symptoms and AIDS among participants in the Brazilian Sex Life Study.

METHODS

The Brazilian Sex Life Study is a cross-sectional population study. The participants answered an anonymous self-responsive inquiry. It was applied to a population sample in 18 large Brazilian cities. Answers given by those who reported having AIDS (75) were compared with those who reported not having AIDS (control; 150). This was a case-control study nested in a cross-sectional population study.

RESULTS

In females, AIDS was associated with "sexual inactivity over the last 12 months" and "does not maintain sexual arousal until the end of the sex act" (P < 0.05) after adjusting for race and thyroid disease. Compared to the control group, men with AIDS had more difficulty becoming sexually aroused (they required more help from their partner to begin the sex act, they required longer foreplay than they wished, they reported losing sexual desire before the end of the sex act, and they required longer to ejaculate than they desired) (P < 0.05). After adjusting for sexual orientation, sex hormone deficiency, depression, and alcoholism, only "does not have sexual desire," "have longer foreplay," and dyspareunia were associated with AIDS.

DISCUSSION AND CONCLUSIONS

The results support the hypothesis that sexual dysfunctions are associated with AIDS. Men with AIDS need more time and stimulation to develop a sexual response, and a significant portion (37%) of women with AIDS reported sexual inactivity over the last 12 months.

Imaging features of renal pathology in the human immunodeficiency virus-infected patient

Renal disease in patients with acquired immunodeficiency syndrome was described before even human immunodeficiency virus was demonstrated to be the causative agent, when the now known human immunodeficiency virus associated nephropathy was first described. Several other pathologic processes mostly relating to the immunodeficiency caused by the virus, such as atypical infections, malignancies, as well as highly active antiretroviral therapy related side affects, have been shown to affect the kidneys. The mortality and morbidity burden is high; therefore, it is paramount the radiologist be familiar with the imaging features of this wide range of diseases processes.

Venous Outflow Obstruction With Retroperitoneal Kaposi's Sarcoma and Treatment With Inferior Vena Cava Stenting

A 26-year-old man presented with acute renal insufficiency, and severe lower extremity swelling. Computed tomographic scan revealed retroperitoneal lymphadenopathy encasing both ureters and the inferior vena cava. He underwent placement of ureteral stents to relieve the obstruction and afterward underwent lymph node biopsy, which revealed Kaposi's sarcoma. He subsequently was diagnosed with acquired immunodeficiency syndrome. Abdominal and lower extremity venous duplex ultrasound did not show any evidence of deep vein thrombosis. The inferior vena cava measured 3.5 mm in diameter and was encased by retroperitoneal lymphadenopathy. Bilateral transfemoral venography and intravascular ultrasound demonstrated significant compression of the inferior vena cava below the renal veins. Endovascular treatment was followed with primary stenting under intravascular ultrasound guidance. His symptoms improved with reduction in swelling. At 1-year follow-up, the patient was ambulatory with mild symptoms, and on venography the iliac vein and inferior vena cava stents were widely patent.

HIV-AIDS: urologic considerations

The prevalence of HIV continues to grow in the United States and worldwide. HIV-positive patients experience many genitourinary disease processes. With improvements in HIV therapy, patients have questions and concerns pertaining to their quality of life. This article reviews conditions such as HIV-related urinary tract infections, urolithiasis, voiding dysfunction, fertility, sexual dysfunction, HIV-related nephropathy, malignancies, and occupational exposure and prophylaxis. Knowledge of the various HIV manifestations of genitourinary conditions and their treatment options benefits clinicians and improves patient outcomes.

The management of chronic prostatitis in men with HIV

Prostatitis is a common urologic diagnosis. Although treatment algorithms are available for this poorly understood entity, several adaptations must be made in order to accommodate the therapeutic needs of HIV-positive patients. The most important consideration when treating HIV-infected patients for prostatitis is their current immune status, whether they are immunocompromised or not (non-progressive disease or reconstituted with highly active antiretroviral therapy). A treatment algorithm for those with chronic bacterial prostatitis (Category II), chronic nonbacterial prostatitis (Category IIIA), and prostatodynia (Category IIIB) is presented in this article. In the HIV-positive patient population, there is a greater likelihood for atypical pathogens including fungi, tuberculosis, anaerobes, and viruses. Because the HIV-infected patient is at increased risk for the development of prostatic abscess and urosepsis than the general population, increased monitoring and evaluation and longer-term appropriately directed antimicrobial therapy are required.
