Cutaneous markers of HIV infection

Retrospective study of psoriasis in people living with HIV: Thailand's experience

Psoriasis in people living with HIV (PLHIV) has been reported as having particular clinical characteristics. However, most of the source data was derived from descriptive studies in Europe and the USA. This study was conducted to compare the characteristics of psoriasis in PLHIV to general psoriasis patients. We retrospectively reviewed the records of 73 cases of psoriasis in PLHIV and of 232 general psoriasis patients who visited a psoriasis clinic in Bangkok, Thailand. Psoriasis in PLHIV predominated in males (78.1%), with an older age of onset, significantly lower rates of nail involvement and psoriatic arthritis, but higher rates of co-infectious diseases than for general psoriasis patients. A low nadir CD4 T-cell count (<100 cells/μl) and CD4 T-cell count at psoriasis diagnosis were associated with a high body surface area (BSA) involvement. The mean BSA involvement in PLHIV was 24. Although 64.4% (47/73) of the PLHIV had moderate-to-high psoriasis severity, 29.8% of those (14/47) only received topical treatment. Acitretin was the most common drug used. Other therapies were rarely used, and no biologics were administered. In conclusion, psoriasis in PLHIV has several clinical features that differ from general psoriasis. PLHIV tend to receive substandard care for psoriasis, even in upper-middle-income countries.

Acute HIV Infection Presenting With Diffuse Plaque Psoriasis Treated With Highly Active Antiretroviral Therapy

Cutaneous diseases such as psoriasis are often the first disease manifestations in HIV+ patients, with greater severity corresponding to a weaker immune system. Despite its prevalence, literature and placebo-controlled studies on the recognition of HIV as a cause of psoriasis are lacking, causing challenges to arise in its treatment. In this article, we illustrate a case of an HIV+ patient whose psoriasis drastically improved after the initiation of highly active antiretroviral therapy (HAART) consisting of bictegravir, emtricitabine, and tenofovir alafenamide. While it is unclear which combination of antiretrovirals is optimal for controlling psoriasis in HIV+ patients, prompt initiation of HAART can significantly improve immune status and psoriasis in HIV+ patients.

Clinicopathological Features of Seborrheic-Like Dermatitis in HIV-Infected Adults: A Single Institutional Descriptive Cross-Sectional Study

BACKGROUND

Atypical and severe clinical presentations of seborrheic-like dermatitis (SLD) are associated with HIV infection, correlating with advanced disease or low CD4 counts. Previous studies documented histological findings characteristic of seborrheic dermatitis in HIV-positive patients.

OBJECTIVE

To expand current knowledge of the clinicopathological characteristics of SLD in South African HIV-seropositive individuals.

METHODS

This prospective study included HIV-seropositive adult patients presenting with SLD to a dermatology clinic from March 2017 to April 2018. A dermatologist established the diagnosis of SLD and the severity of the disease. Detail about antiretroviral therapy (ART), the latest CD4 count, and the viral load was retrieved from the patients' clinical records. Histopathological assessment of the patients' skin biopsies was recorded using standardized data sheets and semiquantifiable grades.

RESULTS

This study included 13 women and 17 men. Fifty percent of patients showed severe or very severe SLD. Six (20.0%) patients presented with erythroderma. Statistical analysis did not show a significant correlation between severity of disease and CD4 count, viral load, or ART, respectively. This study confirmed that the presence of confluent parakeratosis, necrotic keratinocytes, plasma cells, neutrophils with leukocytoclasia, and leukoexocytosis are histopathological clues to SLD occurring in HIV-seropositive patients.

CONCLUSION

SLD in HIV patients may present with varying clinical severity, including erythroderma. The association between the prevalence and severity of SLD with CD4 count, viral load, and ART requires further studies with larger patient populations. The presence of specific histopathological features in a skin biopsy of SLD is a clue to the diagnosis of HIV.

The life-threatening eruption in HIV and immunosuppression

Immunosuppressed patients frequently have skin diseases of mild to moderate intensity. Diagnosis as well as treatment should be performed early to avoid important complications for these patients. Skin eruptions are among these problems. Life-threatening eruptions in HIV and other types of immunosuppression range from acute retroviral syndrome to drug eruptions; immune reconstitution inflammatory syndrome; infection by virus, protozoan, bacteria, or fungi; inflammatory and immune dermatoses; and neoplasia. All of these are discussed in this group of patients.

[Psoriasis and HIV infection, what do French dermatologists do?]

BACKGROUND

The prevalence of psoriasis among patients presenting human immunodeficiency virus (HIV)infection is the same as in the general population, but the disease is more severe and refractory, and management is more complex. The aim of this survey was to assess the practices of French dermatologists concerning both screening for HIV in psoriasis patients and therapeutic management and follow-up of psoriasis patients with HIV.

PATIENTS AND METHODS

An anonymous national survey of practices was conducted by means of a questionnaire emailed to dermatologists in hospital in private practice in France between March and June 2017.

RESULTS

The questionnaire was completed by 262 dermatologists. They indicated that they carried out screening for HIV in psoriasis patients presenting risk factors (79.4%), prior to biotherapy (63.4%) or different systemic treatments other than retinoids (53.1%), if the psoriasis was severe (45.8%), or in the event of worsening (37.8%). 28.7% of practitioners surveyed were in fact treating patients with psoriasis and HIV, with a mean 3.1 patients being followed up. All practitioners prescribe systemic treatment, other than cyclosporine, but they frequently consult an infectious disease specialist before prescribing these therapies. The most widely used biotherapy was etanercept (65.5% of practitioners). More intensive laboratory follow-up was conducted for these patients in 72.1% of cases.

CONCLUSION

French dermatologists do not perform routine screening for HIV in psoriasis patients. However, where infection has been identified, their practices are modified accordingly. Therapeutic choices are consistent with the French recommendations. Nevertheless, recommendations appear necessary concerning HIV screening in this population.

Dermatologic care for lesbian, gay, bisexual, and transgender persons: Epidemiology, screening, and disease prevention

Lesbian, gay, bisexual, and transgender (LGBT) persons face important health issues relevant to dermatologists. Men who have sex with men (MSM) are at higher risk of certain infectious diseases, including HIV, syphilis and other sexually transmitted diseases (STDs), methicillin-resistant Staphylococcus aureus infections, and invasive meningococcal disease, and might be at higher risk of non-infectious conditions, including skin cancer. Recommendations for preventive health care, including screening for HIV and other STDs, sexual health-related vaccinations, and HIV pre-exposure prophylaxis, differ for MSM compared with non-MSM. Women who have sex with women experience disparities in STDs, including chlamydia and HPV. Transgender patients have unique, and often unmet, dermatologic needs during gender transition (also called gender affirmation), related to hormonal therapy and gender-affirming surgery. Familiarity with LGBT health issues and disease-prevention guidelines can enable dermatologists to provide medically appropriate and culturally competent care to LGBT persons.

Prevalence and Clinical Profile of Drug Eruptions among Antiretroviral Therapy-Exposed HIV Infected People in Yaoundé, Cameroon

BACKGROUND

Prevalence and incidence of drug eruptions vary around the world and are influenced by some key factors including HIV infection.

OBJECTIVE

This study aimed to find the peculiarities of drug eruptions in people living with HIV (PLHIV) and on antiretroviral therapy (ART).

METHODS

This was a retrospective cross-sectional study including ART-taking PLHIV, aged 15+ years, followed up between January 2010 and December 2014 at the day-care unit of the Yaoundé Central Hospital, and who presented with drug eruptions after ART initiation.

RESULTS

Of 6,829 ART-experiencing PLHIV, 41 presented with drug eruptions, giving a prevalence of 0.6%. The M/F sex ratio equaled 0.17. The mean age was 41.07 ± 11.36 years. Benign drug eruptions accounted for 83.3%. Milder forms were essentially maculopapular exanthema (36.6%), fixed pigmented erythema (7.3%), and urticaria (4.9%). Severe forms were represented by multiform erythema (4.9%), toxic epidermal necrolysis (2.4%), and drug hypersensitivity syndrome (2.4%). The Zidovudine + Lamivudine + Efavirenz ART-protocol was received by 48.8% of patients and 69% of patients were receiving Cotrimoxazole prophylaxis. Nevirapine, Efavirenz, Zidovudine, and Cotrimoxazole were suspected as the potential causes in 43.7%, 4.8%, 2.4%, and 26.8% of cases, respectively.

CONCLUSION

Drug eruptions seem infrequent among ART-exposed HIV infected adult Cameroonians.

A Multi-Group Latent Class Analysis of Chronic Medical Conditions Among Men Who Have Sex with Men

Until recently, research on the health of gay and other men who have sex with men (MSM) has focused on risk for and the health consequences of HIV and other sexually transmitted infections. A multigroup latent class analysis examined a range of lifetime chronic medical conditions (CMCs) among MSM. Covariates included sociodemographics, substance use, psychological distress, and HIV serostatus. A two-class model best fit the medical condition data: a low probabilities class for most CMCs and a moderate to high probabilities (MHP) class. HIV serostatus was associated with increased within-class probabilities for some CMCs, particularly gastrointestinal and skin disorders. Only increasing age and use of erectile dysfunction drugs were directly associated with increased odds of being in the MHP class whereas methamphetamine use, identifying as gay, and lower alcohol use were indirectly associated. Implications of the findings for future research and the health care needs of MSM are discussed.

[Skin symptoms associated with human immunodeficiency virus infection]

The recently observed accelerated increase of human immunodeficiency virus infection in Hungary poses a major public concern for the healthcare system. Given the effective only but not the curative therapy, prevention should be emphasized. Current statistics estimate that about 50% of the infected persons are not aware of their human immunodeficiency virus-positivity. Thus, early diagnosis of the infection by serological screening and timely recognition of the disease-associated symptoms are crucial. The authors' intention is to facilitate early infection detection with this review on human immunodeficiency virus-associated skin symptoms, and highlight the significance of human immunodeficiency virus care in the everyday medical practice.

Chronic pruritus in HIV-positive patients in the southeastern United States: its prevalence and effect on quality of life

BACKGROUND

Prevalence of chronic pruritus in HIV-positive patients is an underevaluated topic in the United States. The characteristics, severity, and quality of life (QOL) in patients with HIV and chronic pruritus have not been well documented using validated tools.

OBJECTIVES

We sought to assess the prevalence and intensity of chronic pruritus and its effect on QOL in HIV-positive patients in a US population.

METHODS

HIV-positive patients (n = 201) were asked to complete a sociodemographic data form and 2 itch questionnaires. Patients with itching rated their itch intensity on a numeric visual analog scale. Laboratory parameters were obtained from patients' medical records.

RESULTS

The prevalence of chronic itch in the study group was 45% with an average visual analog scale score of 5.93 during an itch episode. Patients with high visual analog scale score had significantly decreased QOL. Patients with HIV reported greater negative impact of pruritus on daily lives.

LIMITATIONS

Because of the cross-sectional design, this study demonstrates an association between HIV and pruritus but cannot prove causation.

CONCLUSION

Patients with HIV surveyed in a large clinic in the southeastern United States have a high prevalence of pruritus; HIV pruritus has a significant effect on QOL and itch is the most common skin manifestation found in this population.

Bacillary angiomatosis presenting as a pyogenic granuloma of the hand in an otherwise apparently healthy patient

Bacillary angiomatosis is a rare opportunistic infection caused by the gram-negative bacteria Bartonella. The infection is strongly related to human immunodeficiency virus (HIV) infection, and hence, the diagnosis is usually considered based on the fact that the patient is HIV positive. We report on a case of bacillary angiomatosis presenting as a pyogenic granuloma of the hand in an otherwise apparently healthy man. The report is aimed to increase the awareness of hand surgeons that this serious disease may be the first clinical manifestation of HIV infection. The case also demonstrates that once the correct diagnosis is made, medical treatment alone may be sufficient to cure massive recurrent lesions.

Current progress and challenges in HIV gene therapy

HIV-1 causes AIDS, a syndrome that affects millions of people globally. Existing HAART is efficient in slowing down disease progression but cannot eradicate the virus. Furthermore the severity of the side effects and the emergence of drug-resistant mutants call for better therapy. Gene therapy serves as an attractive alternative as it reconstitutes the immune system with HIV-resistant cells and could thereby provide a potential cure. The feasibility of this approach was first demonstrated with the 'Berlin patient', who was functionally cured from HIV/AIDS with undetectable HIV-1 viral load after transplantation of bone marrow harboring a naturally occurring CCR5 mutation that blocks viral entry. Here, we give an overview of the current status of HIV gene therapy and remaining challenges and obstacles.

Chronic pruritus in the absence of specific skin disease: an update on pathophysiology, diagnosis, and therapy

Chronic pruritus is a major and distressing symptom of many cutaneous and systemic diseases and can significantly impair the patient's quality of life. Pruritus perception is the final result of a complex network involving dedicated nerve pathways and brain areas, and an increasing number of peripheral and central mediators are thought to be involved. Itch is associated with most cutaneous disorders and, in these circumstances, its management overlaps with that of the skin disease. Itch can also occur without associated skin diseases or primary skin lesions, but only with nonspecific lesions secondary to rubbing or scratching. Chronic itch with no or minimal skin changes can be secondary to important diseases, such as neurologic disorders, chronic renal failure, cholestasis, systemic infections, malignancies, and endocrine disorders, and may also result from exposure to some drugs. The search for the cause of pruritus usually requires a meticulous step-by-step assessment involving careful history taking as well as clinical examination and laboratory investigations. Few evidence-based treatments for pruritus are available. Topical therapy, oral histamine H(1) receptor antagonists, and phototherapy with UV radiation can target pruritus elicitation in the skin, whereas antiepileptic drugs, opioid receptor antagonists, and antidepressants can block signal processing in the CNS.

Dermatology of the patient with HIV

Cutaneous diseases occur in most people infected with human immunodeficiency virus (HIV) and at a higher rate than people not infected with HIV. Common HIV-related rashes and rashes made unusual by HIV infection are reviewed.

Knowledge and attitude regarding human immunodeficiency virus/acquired immunodeficiency syndrome in dermatological outpatients

BACKGROUND

Dermatologists are often the first-line specialists who recognize and diagnose human immunodeficiency virus (HIV) infection because of pathognomic skin signs. It is therefore important to investigate attitudes and knowledge regarding HIV/acquired immunodeficiency syndrome (AIDS) amongst dermatological patients in order to provide information for dermatologists and to draw their attention to the issues.

OBJECTIVES

Awareness of HIV/AIDS, its prevention, and hypothetical behaviour were surveyed in dermatological outpatients.

PATIENTS/METHOD

The anonymous cross-sectional survey was conducted with consecutive German-speaking outpatients aged 18-65 years, who registered at the dermatological outpatient's clinic (excluding venereology, genitourinary or HIV medicine) of the University of Munich (Germany).

RESULTS

Three hundred forty-seven (77.5%) questionnaires were accepted for analysis. Most of the patients knew about HIV incurability (89.4%), HIV transmissibility during needle sharing (95.3%), or vaginal (87.4%) and anal intercourse (79.5%), as well as about HIV prevention by condom use (97.8%), and use of single needles (76.2%). However, knowledge gaps and misconceptions were detected regarding the risk of HIV transmission during oral sex, and the efficacy of sexual fidelity and avoidance of blood transfusions in HIV prevention. The lowest knowledge level (< 50% correct answers) was detected in patients aged 50-59 years, in unemployed, divorced/widowed, and in those without or with incomplete school education.

CONCLUSIONS

Patient education about HIV/AIDS in dermatological ambulant settings should be performed differentially with regard to socio-demographic factors, and focused on the topic of oral sexual HIV transmission and on some other specific misconceptions.

Inflammatory Noninfectious Dermatoses of HIV

Since the advent of HIV/AIDS, a variety of inflammatory noninfectious skin conditions have been described in HIV-infected patients. This review will discuss a group of inflammatory, noninfectious dermatoses that, although not exclusive to HIV/AIDS, are commonly observed in HIV-infected patients and pose an apparent paradox in a disease that supposedly involves suppression of cellular immunity.

Herpes zoster ophthalmicus in otherwise healthy children

PURPOSE

To evaluate the complications of herpes zoster ophthalmicus (HZO) in children.

DESIGN

Prospective-observational case series.

METHODS

Ten healthy patients (five boys, five girls) with HZO were prospectively followed. Data regarding best-corrected visual acuity, biomicroscopy, intraocular pressure, corneal sensitivity, and funduscopy were collected. The median duration of follow-up was 19 months (range eight to 78 months).

RESULTS

The mean age at presentation was 8.7 years (range two to 14 years +/-3.95). At last visit, two patients (20%) had decreased visual acuity and nine (90%) had some degree of abnormal corneal sensitivity and corneal opacity despite good final visual acuity.

CONCLUSION

In general, HZO seems to have a good prognosis in healthy children; nonetheless, some cases can present severe eye complications causing visual loss.
