Papular follicular eruptions in human immunodeficiency virus-positive patients in South Africa

A study of clinicopathological correlation of pruritic papular eruptions in HIV patients

Context:

Pruritic papular eruption (PPE) is a chronic eruption of papular and pruritic lesions of unknown etiology, symmetrically distributed over trunk and extremities. These are common cutaneous manifestations in HIV patients. It is an important cause of HIV-related morbidity. PPE can be the first marker of HIV. Their etiology, histopathological findings, and associated factors vary from region to region. There are no clear data available on the etiology, exact spectrum of the condition, histopathological findings, or treatment of PPE.

Aims:

The study is aimed at documenting the etiology, CD4 count, and its histopathological correlation in HIV-infected patients.

Settings and Design:

An observational study conducted in Government Medical College, Patiala.

Subjects and Methods:

Two-year data regarding history, HIV status, cluster of differentiation 4 (CD4) cell count, and skin biopsy of clinically suspected PPE patients with known HIV status were analyzed.

Statistical Analysis Used:

All the results were then statistically analyzed. Categorical data were analyzed by Chi-square test, and one-way Spearman's rho test was used for multiple group comparison.

Results:

Data of 50 eligible patients were analyzed. The majority of the patients were female (between 21 and 50 years of age). The most common histopathological patterns were of papular urticaria, scabies, and drug reaction, and the others less common PPE were polymorphic light eruption and eosinophilic folliculitis. Patients with papular urticaria (32%) had significantly lower mean CD4 counts (157 cells/mm³), while in scabies, the mean CD4 count (376 cells/mm³) was higher.

Conclusions:

We conclude that histopathology helps in specifying the pattern of PPE and its etiology. It can be a marker of advanced HIV infection. Thus, correlation between the histopathology, clinical diagnosis, and CD4 counts helps to know the disease process.

Operational research on the correlation between skin diseases and HIV infection in Tigray region, Ethiopia

BACKGROUND

In Ethiopia, skin diseases are among the leading causes of outpatient attendance to primary health service. Correlation of skin diseases and HIV has long been recognized and used to guide medical management in resource-limited settings. Therefore, this study aims to assess the correlation of skin diseases and HIV infection, to estimate epidemiological distribution in the study area, and to provide health workers of skin indicators for HIV early detection.

METHODS

The operational research was designed as a case-control study and carried out in three intervention districts of Tigray region; baseline and final data on skin diseases and HIV were compared with those of three control districts matched for population size, density, and environmental characteristics. Health workers of intervention districts were trained on skin diseases/STIs diagnosis and treatment. Data were collected from study and control districts and then analyzed at the Italian Dermatological Centre (IDC) in Mekele.

RESULTS

In the research period, a total of 1044 HIV positive patients were detected. Disorders of skin and mucous membranes statistically related with HIV (P < 0.05) were tongue papillary atrophy (80%), oral hairy leukoplakia (69%), herpes zoster (66%), oral candidiasis (50%), pruritic papular eruption (43%), condylomata acuminata (38%), and telogen effluvium (27%).

CONCLUSIONS

The high frequency of oral disorders and telogen effluvium is not described in literature and may be indicative for case detection. Operational research offers significant gains on health service delivery and outcomes at relatively low cost and in a short timeframe.

Comparison between Malassezia Folliculitis and Non-Malassezia Folliculitis

Background

Among the various types of folliculitis, differentiation of Malassezia folliculitis (MF) from other forms of folliculitis is important because it is usually treated with antifungal agents.

Objective

We attempted to find a method to enhance the detection rate of MF, and examined the differences in the clinical manifestation between MF and non-MF (NMF).

Methods

We performed a retrospective study involving patients with folliculitis who were previously diagnosed with MF or NMF on the basis of serial tissue sectioning and diastase-Periodic acid-Schiff (d-PAS) staining findings. The clinical features of MF and NMF were compared.

Results

Among a total of 100 folliculitis patients, 20 were diagnosed with MF and 80 with NMF. Tissues from the 80 patients with NMF were sectioned serially into 10 slices and stained with hematoxylin and eosin stain; among these, 10 had many round-to-oval yeast organisms in the hair follicles that confirmed MF. Finally, d-PAS staining was used to detect the presence of yeast in the NMF slides. Notably, among the 70 d-PAS-stained samples, yeast organisms were found in 6 samples, confirming MF. As a result, the diagnosis of 16 patients changed from NMF to MF. Compared with NMF, MF showed major involvement of the trunk and low involvement of the face and legs as well as male predilection.

Conclusion

Physicians should consider serial sectioning and/or d-PAS staining of folliculitis lesions, particularly of those on the trunk of male patients, even if no yeast organisms are detected initially.

Pruritic papular eruption in HIV: a case successfully treated with NB-UVB

Pruritic papular eruption (PPE) is a skin disease characterized by the eruption of itching papules on the extremities, face, and trunk; it is quite frequent in HIV-positive patients especially during the advanced immunosuppressive stage. PPE usually improves or heals when antiretroviral therapy restores the immune system function, but in some cases, it can take several months, and a symptomatic treatment for PPE is required. Systemic antihistamines, topical steroids, topical tacrolimus, itraconazole, pentoxyphilline, and ultraviolet B phototherapy have been proposed in cases of persisting PPE, but an elective treatment has not yet been found. We describe the case of a black patient affected by PPE, nonimproving with antiretroviral treatment, and resistant to topical steroids and oral antihistamines; a satisfactory and speedy result was achieved with narrow-band ultraviolet B phototherapy.

Exuberant clinical presentation of probable Malassezia folliculitis in a young nonimmunosuppressed patient

Malassezia folliculitis is an inflammatory disorder observed in both immunocompetent and immunosuppressed patients. The authors describe an unusual and exuberant presumed case affecting the face, trunk and upper limbs of a 12-year-old nonimmunosuppressed patient. Although the agent was not identified by culture, the clinical and histopathological aspects plus the response to specific treatment support the diagnosis of Malassezia folliculitis. The only possible predisponent cause observed on the patient was greasy skin. Repetitive cultures were negative. Treatment with itraconazol promoted apparent cure, however, the patient relapsed twelve months later.
