Antifungal Nail Lacquer for Enhanced Transungual Delivery of Econazole Nitrate. Pharmaceutics 2022; 14:pharmaceutics14102204. [PMID: 36297639 PMCID: PMC9607990 DOI: 10.3390/pharmaceutics14102204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Revised: 10/07/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022] Open
Abstract
The fungal disease of the nail, onychomycosis, which is also the most prevalent nail disturbance, demands effective topical treatment options considering the possible adverse effects of systemic antifungal therapy. The current work is focused on development of an adhesive and resistant, drug-delivering and permeation-enhancing polymeric film containing econazole nitrate (ECN) for topical antifungal treatment. The development of the lacquer formulation was guided by the Quality by Design approach to achieve the critical quality attributes needed to obtain the product of desired quality. Eudragit RSPO at 10% w/w was found to be the ideal adhesive polymer for the application and an optimal permeation-enhancing lacquer formulation was achieved by the optimization of other formulation excipients, such as plasticizer and the solvent system. Additionally, novel experimental enhancements introduced to the research included refined D50 drying time and drying rate tests for lacquer characterization as well as a multi-mechanism permeation-enhancing pre-treatment. Moreover, a practical implication was provided by a handwashing simulation designed to test the performance of the lacquer during actual use. In vitro drug release testing and ex vivo nail permeation testing demonstrated that the optimized nail lacquer performed better than control lacquer lacking the permeation enhancer by achieving a faster and sustained delivery of ECN. It can be concluded that this is a promising drug delivery system for topical antifungal treatment of onychomycotic nails, and the novel characterization techniques may be adapted for similar formulations in the future.

Abstract
Immune thrombocytopenia (ITP) is an acquired autoimmune disease that occurs in adults and children. In Malaysia, the clinical practice guideline (CPG) for the management of ITP was issued in 2006, which focused almost exclusively on primary ITP (pITP), and only a few secondary ITP (sITP) forms were addressed. All published (twenty-three) sITP articles among children and adults in Malaysia, identified on the academic databases were retrieved. The articles were published between 1981 and 2019, at a rate of 0.62 publications per year. The publications were considered low and mainly focused on rare presentation and followed-up of secondary diseases. This review revealed that sITP in Malaysia is commonly associated with autoimmune diseases (Evan’s syndrome, SLE and WAS), malignancy (Kaposi’s sarcoma and breast cancer) and infection (dengue haemorrhagic fever, Helicobacter pylori and hepatitis C virus). The relationship between ITP and autoimmune diseases, malignancy and infections raise the question concerning the mechanism involved in these associations. Further studies should be conducted to bridge the current knowledge gap, and the further information is required to update the existing CPG of management of ITP in Malaysia.

[PMID: 34859509 DOI: 10.1111/jop.13266] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 11/03/2021] [Accepted: 11/25/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Oral thrush, a clinical condition due to an overgrowth of Candida yeasts in the oral cavity, is prominent in patients with immunosuppression. As recent updates on oral thrush in South-East Asian (SEA) countries are lacking, this review aimed to address the epidemiology, clinical features and distribution of Candida species, based on published studies in SEA countries over the last two decades. METHODS Published studies on oral candidiasis (2000-2020) were retrieved from PubMed, Scopus, ISI Web of Science and Google Scholar databases to provide information on the incidence and factors affecting oral thrush cases in SEA countries. RESULTS A total of 22 cross-sectional studies involving 3697 subjects from five SEA countries were reviewed in this study. The most frequently reported population were human immunodeficiency virus (HIV)-infected patients. The overall incidence rates amongst HIV-infected patients ranged from 20.7% to 97.0%, while incidence rates ranging from 0% to 72.7% were recorded for non-HIV-infected populations. Pseudomembranous candidiasis and erythematous candidiasis were the most common clinical presentations of oral thrush lesions. Candida albicans was the most common species identified in SEA studies. As oral thrush assessments were made merely based on clinical diagnosis, culture results were not available for most studies. CONCLUSION This review highlights that most studies reporting on oral candidiasis in SEA countries were based on HIV-positive patients. Data are still lacking on oral candidiasis amongst non-HIV immunocompromised and immunocompetent patients. Increasing awareness on the diagnosis, treatment and consequences of this infection, and improved laboratory methods are essential for the management of oral candidiasis in this region.

Abstract
This study aimed to document the dermatoses and their relationships with CD4+ T lymphocyte counts and clinical stages of disease among people living with HIV followed by our Clinical Department, to investigate the effect of antiretroviral therapy (ART) on findings and to compare with real-world data. Medical records of people living with HIV were analyzed retrospectively in our outpatient clinic from January 2005 to June 2017. A total of 500 patient files were examined. 179 patients with dermatoses were included in the study. Demographic data, clinical and laboratory findings, dermatological findings, type and distribution of lesions, serological and histopathological examinations, diagnosis, treatment, and follow-up of patients were transferred to data forms. 84.4% of the patients were male and the mean age was 38.65 ± 11.6 years. The median CD4+ T lymphocyte count was 253/mm3 (range:0-1067). At least one dermatosis was present in 69.3% of the patients. Compared with their median CD4+ T lymphocyte counts, the ratio of CD4+ T lymphocytes was significantly lower in the group with three or more dermatoses (p = 0.019). Condyloma acuminatum (15.1%), drug eruption (13.4%), seborrheic dermatitis (11.7%), oral candidiasis (11.2%), dermatophytoses (11.2%), syphilis (8.4%), Kaposi's sarcoma (8.4%), and telogen effluvium (8.4%) were the most common dermatoses. Kaposi sarcoma (KS), oral candidiasis, onychomycosis, and molluscum contagiosum were significantly higher in the CD4+ T lymphocyte <200/mm³ group when CD4+ T lymphocyte threshold value was determined as 200/mm³. Compared with other TDF/FTC-containing regimens, a significantly higher proportion of alopecia was reported in patients receiving TDF/FTC/EVG/c (p = 0.007). Dermatoses may be a good clinical marker for detecting clinical stage and diagnosing HIV infection; also, there may be a significant increase in the number of dermatoses in advanced stages. Although there are only a few studies in the literature, it should be kept in mind that ART-associated alopecia rates may increase nowadays when ART is targeted at everyone.

Abstract
INTRODUCTION A dermatophytoma is a mass of hyphae that is observed at direct examination, it responds poorly to treatment with antifungal drugs, some authors have proposed that it is actually a biofilm. This pathology is underdiagnosed, and its true incidence is unknown. OBJECTIVES This study presents the clinical findings of dermatophytoma in HIV/AIDS patients from Colombia presenting onychomycosis. MATERIAL AND METHODS A transversal observational descriptive study was carried out in a third level university hospital. One hundred thirty HIV positive patients diagnosed using ELISA and Western Blot that presented nail lesions on their hands and/or feet compatible with onychomycosis were included. Samples taken from affected nails were observed in direct examination with KOH and seeded onto Sabouraud agar, mycosel agar and dextrose-potato agar. Molds were identified based on macroscopic and microscopic characteristics. RESULTS Six (4.6%) individuals presented dermatophytoma. Average age was 43 years (range 33-50); nails more commonly affected (5/6) were on the toes, principally the hallux. Clinical manifestations included a yellow or white, rounded or linear dense area on the nail. Superficial white onychomycosis was present in 83.3% of the patients. Fungal cultures were obtained in only 5 patients; Trichophyton mentagrophytes complex was found in 2 individuals while T. rubrum, T. tonsurans and Epidermophyton floccosum were in the other 3. Average cell count for CD4+T lymphocytes was 86.8 cells/mm3 (range 9-282). CONCLUSIONS This is the first report in Colombia of dermatophytoma in HIV/AIDS patients, most of them had a CD4+ T lymphocytes count less than 200 cells/mm3. Several clinical forms of onychomycosis were observed, the most frequent was the white superficial onychomycosis.

Abstract
INTRODUCTION The majority of patients with Human Immunodeficiency Virus (HIV) will have cutaneous manifestation during their disease course. We report the spectrum of cutaneous manifestations and clinicopathological concordance in the diagnosis of skin diseases in patients with HIV. METHODS A retrospective review of all cutaneous manifestations of HIV-infected patients with skin biopsy-proven histopathological confirmation, treated in the University of Malaya Medical Centre, from 2016 till 2018, was performed. Clinical characteristics and histopathological correlation of these patients were reviewed. RESULTS A total of 38 cases were included where the median age was 40.5 (interquartile range (IQR) 13.3). The median duration of HIV diagnosis to the development of skin disease was 3 years (IQR 7.8). Majority of our patients were male (89.5%, n = 34), and the commonest mode of transmission is men who have sex with men (36.8%, n = 14). Most patients (92.1%, n = 35) had Acquired Immunodeficiency Syndrome when they presented with skin diseases, predominantly non-infectious types (51.4%, n = 19). Commonest skin diseases include eczema (n = 7) and pruritic papular eruption of HIV (n = 6). Papules and plaques were the commonest morphology for both infectious and non-infectious skin diseases. Duration of HIV diagnosis (P = 0.018) and non-compliance to Highly Active Antiretroviral Therapy (HAART) (P = 0.014) were significantly associated with the development of non-infectious skin diseases. Overall, clinicopathological concordance was 84.2% in our centre. CONCLUSION A wide spectrum of cutaneous diseases can occur in HIV patients depending on the degree of immunosuppression. skin biopsy along with appropriate stains, and microbiological cultures are important in helping clinicians clinch the right diagnosis.

Burden of Talaromyces marneffei infection in people living with HIV/AIDS in Asia during ART era: a systematic review and meta-analysis. BMC Infect Dis 2020; 20:551. [PMID: 32727383 PMCID: PMC7392840 DOI: 10.1186/s12879-020-05260-8] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2019] [Accepted: 07/16/2020] [Indexed: 12/11/2022] Open
Abstract
Background Talaromyces marneffei (TM) is a dimorphic fungus mainly prevalent in Southeast Asian countries, which often causes disseminated life-threatening infection. TM infection often occurs in HIV/AIDS patients even in the antiretroviral therapy (ART) era. However, there has as yet, not been a systematic analysis of the prevalence of TM infection in HIV-infected populations in Asia. Methods In this study, we searched Pubmed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and WanFang from inception to 21 November 2018 for studies reporting TM infection in people living with HIV/AIDS (PLWHA). Our meta-analysis included studies investigating the prevalence of TM infection in PLWHA. Reviews, duplicate studies, and animal studies were excluded. A random effects model was used to estimate pooled prevalence, and meta-regression analysis was conducted to explore potential factors for heterogeneity. Results 159,064 patients with HIV infection in 33 eligible studies were included in our meta-analysis. The pooled prevalence of TM infection in PLWHA was 3.6%. Vietnam had the highest prevalence (6.4%), followed by Thailand (3.9%), China (3.3%), India (3.2%) and Malaysia (2.1%). In China, TM infection was most prevalent in South China (15.0%), while the burden in Southwest China was not very heavy (0.3%). CD4+ T-cell counts below 200 cells/mm3 contributed to the increased risk of TM infection in PLWHA (OR 12.68, 95%CI: 9.58–16.77). However, access to ART did not significantly decrease the risk of TM infection in PLWHA. Conclusions The burden of TM infection in Asia is heavy, and varies from region to region. PLWHA in lower latitude areas are more likely to suffer from TM infection. Optimization of diagnostic tools and universal screening for TM in vulnerable people to ensure early case detection and prompt antifungal treatment should be considered.

Abstract
Abstract
Background
HIV infection and meningitis are diseases which are known to precipitate malnutrition. Skin manifestations of malnutrition are easy to identify. We tried to describe the skin manifestations of malnutrition in HIV-positive patients with meningitis.
Setting
Patients included in the study were from a tertiary referral hospital in South India.
Methods
In a cross-sectional observational design, we studied 56 adult [> 14 years] HIV-seropositive patients with meningitis by clinical assessment of skin manifestations of malnutrition.
Results
Skin wasting (31.5%), hyperpigmentation of skin (22.2%) and skin ulceration (16.4%) were the chief skin manifestations of malnutrition in HIV-positive patients with meningitis.
Conclusions
Our study shows that certain cutaneous features of malnutrition like skin ulcers, skin wasting and hypo pigmentation are common in HIV patients with meningitis.

Abstract
BACKGROUND The affecting factors of mucocutaneous manifestations in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients remain unclear in China. METHODS A retrospective analysis was conducted among HIV/AIDS patients in Yunnan, China. The demographic data, mucocutaneous manifestations, CD4 cell counts, and antiretroviral therapy (ART) regimens were collected. The effects of CD4 cell count and ART on the spectrum of mucocutaneous manifestations were evaluated. RESULTS Among 508 HIV/AIDS patients, 86.0% of cases showed mucocutaneous manifestations. The average CD4 cell count (176 cells/μl) of the patients with manifestations was significantly lower than those without manifestations (328 cells/μl) (P < 0.001). Diseases such as herpes zoster, oral candidiasis, condyloma acuminatum, genital herpes, oral leukoplakia, talaromycosis, cryptococcosis, and HIV-PPE (pruritic papular eruption) were represented quite frequently in patients with CD4 cell count <200 cells/μl (P < 0.05), but eczema was suffered by those with CD4 cell count ≥200 cells/μl (P < 0.05). ART could decline the incidence of herpes zoster, oral candidiasis, condyloma acuminatum, genital herpes, oral leukoplakia, talaromycosis, and cryptococcosis (P < 0.05). CONCLUSIONS Mucocutaneous manifestations are closely related to the CD4 cell count and can be used as early predictors of HIV/AIDS and immune status in clinic. ART could reduce the incidence of certain mucocutaneous manifestations.

Abstract
Seborrheic dermatitis (SD) is reported to have distinct clinical and histologic presentations in patients with HIV infection. Here we present 20 cases to further define some of these unique characteristics. Common features include erythematous, scaly papules, and plaques involving areas beyond the typical seborrheic distribution; thick, greasy scale on the scalp; and an increased frequency of erythroderma. Histologically, there is widespread parakeratosis, spongiosis, and necrotic keratinocytes. Treatment is often difficult, requiring prolonged use of oral and topical antifungals and corticosteroids as well as antibiotics for bacterial superinfection. SD with these features represents a marker for HIV infection and can aid in early diagnosis.

Abstract
Objectives The authors have conducted a systematic review of oral manifestations of HIV from studies conducted in Asia to establish the characteristics and prevalence of individual oral manifestations in Asia, and to assess the direction of future research studies on oral manifestations of HIV in Asia. Material and Methods The electronic retrieval systems and databases searched for relevant articles were PubMed [MEDLINE], EBSCO, and EMBASE. The search was for limited articles published in English or with an English abstract and articles published during the period January 1995 to August 2014. The authors reached a final overall sample of 39 studies that were conducted in Asia. Results The median population size among all studies was 312.7 patients. Oral candidiasis [OC] was the most common oral manifestation [37.7%] in studies conducted in Asia. The overall prevalence of oral hairy leukoplakia and melanotic hyperpigmentation was computed to be 10.1% and 22.8% respectively. Thailand and India are primarily countries with maximum research on oral manifestations. Conclusions The research on oral manifestations of HIV in Asia has to upgrade to more interventional and therapeutic studies rather than the contemporary cross- sectional epidemiological descriptive studies. The authors have given suggestions and future directions for the implementation of clinical research of oral manifestations in HIV patients. Key words:Oral manifestations, HIV/AIDS, Asia, Systematic review.

Abstract
In the United States, histoplasmosis is generally thought to occur mainly in the Ohio and Mississippi River Valleys, and the classic map of histoplasmosis distribution reflecting this is second nature to many U.S. physicians. With the advent of the HIV pandemic reports of patients with progressive disseminated histoplasmosis and AIDS came from regions of known endemicity, as well as from regions not thought to be endemic for histoplasmosis throughout the world. In addition, our expanding armamentarium of immunosuppressive medications and biologics has increased the diagnosis of histoplasmosis worldwide. While our knowledge of areas in which histoplasmosis is endemic has improved, it is still incomplete. Our contention is that physicians should consider histoplasmosis with the right constellations of symptoms in any febrile patient with immune suppression, regardless of geographic location or travel history.

Abstract
In this study, 100 HIV-positive cases (63 men, 37 women) with skin findings were included. The mean CD4 T cell count was 253 cells/mm(3). A total of 235 dermatological manifestations were seen. The common infectious dermatoses were candidiasis (21%), Staphylococcal skin infections (20%), dermatophytoses (14%) and herpes zoster (6%). Among the non-infectious dermatoses were papular pruritic eruptions (20%), xerosis/ichthyosis (20%) and seborrhoeic dermatitis (16%). Statistically significant association (p < 0.05) with CD4 T cell count was seen in pyodermas, dermatophytoses and papular pruritic eruptions. Adverse drug reactions, diffuse hair loss, straightening of hairs and pigmentary changes were also noted. Although there was an absence of Kaposi's sarcoma in our study, a case of verrucous carcinoma of penis was noted.

Abstract
BACKGROUND AND AIMS The HIV infection is associated with several dermatological conditions which may be the first pointer towards the existence of HIV. These may present with unusual and atypical manifestations in the course of the HIV infection. Keeping this in mind, the seroprevalence of HIV in these persons and the spectrum of the skin and the mucocutaneous lesions in the HIV positive patients was studied. METHODS The current prospective study was conducted over a period of 3 years (2006-2008). A total of 604 persons who had any kind of skin and mucocutaneous infections were screened for the HIV infection as per the NACO guidelines after recording their clinical and epidemiological profiles. RESULTS Out of the 604 patients who were screened, 90(14.90%) were seropositive for the HIV-I antibodies and none was positive for the HIV-2 antibodies. Seventy three point thirty three percent 73.33 of the seropositive patients were in the age group of 15-40 years, with a male-female ratio of 1:1.05. The heterosexual route was the most common mode of transmission (86.6%).A wide range of infectious and noninfectious lesions were observed. In the HIV seropositive patients, oral candidiasis (32.22%) was the most common infectious disease which was observed, followed by herpes zoster (13.33%), genital warts (7.77%) and genital herpes (6.66%). The most common noninfectious manifestation was seborrhoic dermatitis (8.88%), followed by pruritic papular eruptions (7.77%). CONCLUSION As there is a high prevalence of the HIV infection in patients who have skin and mucocutaneous disorders, the doctors, during the investigation of these patients, must have a high level of suspicion for the HIV infection in their mind. An early detection of HIV optimizes the chemoprophylaxis for many opportunistic mucocutaneous disorders.

Abstract
Acquired immunodeficiency syndrome (AIDS) is characterized by decreased immunity, making a patient more susceptible to opportunistic infections which can have cutaneous manifestations. The aim of this study was to evaluate the local immunity of the skin through morphological and immunohistochemical analysis. Skin samples of 52 women, 27 without AIDS and 25 with AIDS, autopsied in an academic referral hospital in Brazil were evaluated. The autopsy reports and medical records were reviewed, and histochemical Hematoxylin-eosin, Picrosirius red, and Verhoeff stains as well as morphometric (Image J and KS-300 Kontron-Zeiss) and immunohistochemical (S-100 and anti-IgA) analyses of the skin were performed. Women with AIDS presented a thinner epidermis than women without AIDS (33.33 [12.00-317.66] vs 67.42 [12.00-530.02] μm; p < 0.001), with a lower number of epithelial cell layers (4.00 [2.00-11.00] vs 4.00 [2.00-16.00]; p < 0.001), a smaller cell diameter (12.92 [6.00-28.87] vs 24.32 [6.00-33.12] μm; p < 0.001), and a lower number of Langerhans cells (LC) (12.58 [0.00-81.74] vs 31.44 [0.00-169.77] LC/mm(2); p < 0.001). The dermis contained more collagen fibers (8.20 % [2.40-19.40] vs 6.30 % [0.40-13.90]; p < 0.001). Some of these parameters were negatively correlated with viral load and positively correlated with the number of CD4+ T-lymphocytes. We conclude that a decrease of the local skin immunity in women with AIDS may contribute to the development of skin lesions.

Abstract
In the last 15 years, the genus Malassezia has been a topic of intense basic research on taxonomy, physiology, biochemistry, ecology, immunology, and metabolomics. Currently, the genus encompasses 14 species. The 1996 revision of the genus resulted in seven accepted taxa: M. furfur, M. pachydermatis, M. sympodialis, M. globosa, M. obtusa, M. restricta, and M. slooffiae. In the last decade, seven new taxa isolated from healthy and lesional human and animal skin have been accepted: M. dermatis, M. japonica, M. yamatoensis, M. nana, M. caprae, M. equina, and M. cuniculi. However, forthcoming multidisciplinary research is expected to show the etiopathological relationships between these new species and skin diseases. Hitherto, basic and clinical research has established etiological links between Malassezia yeasts, pityriasis versicolor, and sepsis of neonates and immunocompromised individuals. Their role in aggravating seborrheic dermatitis, dandruff, folliculitis, and onychomycosis, though often supported by histopathological evidence and favorable antifungal therapeutic outcomes, remains under investigation. A close association between skin and Malassezia IgE binding allergens in atopic eczema has been shown, while laboratory data support a role in psoriasis exacerbations. Finally, metabolomic research resulted in the proposal of a hypothesis on the contribution of Malassezia-synthesized aryl hydrocarbon receptor (AhR) ligands to basal cell carcinoma through UV radiation-induced carcinogenesis.

Abstract
Since the first reports of AIDS, skin involvement has become a burdensome stigma for seropositive patients and a challenging task for dermatologist and infectious disease specialists due to the severe and recalcitrant nature of the conditions. Dermatologic manifestations in AIDS patients act as markers of disease progression, a fact that enhances the importance of understanding their pathogenesis. Broadly, cutaneous disorders associated with HIV type-1 infection can be classified as primary and secondary. While the pathogenesis of secondary complications, such as opportunistic infections and skin tumours, is directly correlated with a decline in the CD4+ T cell count, the origin of the certain manifestations primarily associated with the retroviral infection itself still remains under investigation. The focus of this review is to highlight the immunological phenomena that occur in the skin of HIV-1-seropositive patients, which ultimately lead to skin disorders, such as seborrhoeic dermatitis, atopic dermatitis, psoriasis and eosinophilic folliculitis. Furthermore, we compile the latest data on how shifts in the cytokines milieu, impairments of the innate immune compartment, reactions to xenobiotics and autoimmunity are causative agents in HIV-1-driven skin diseases. Additionally, we provide a thorough analysis of the small animal models currently used to study HIV-1-associated skin complications, centering on transgenic rodent models, which unfortunately, have not been able to fully unveil the role of HIV-1 genes in the pathogenesis of their primarily associated dermatological manifestations.

Abstract
OBJECTIVES To evaluate the use of grey/distal banded nails as an indicator of advanced immunosuppression, and thus eligibility for ART, in resource poor settings. METHODS We tested whether grey/distal banded nails and/or oral pigmentation could be used to identify patients with low CD4 cell counts at two cut-offs: <200 and <350 cells/microl in ART naive adults. RESULTS Four hundred and three nail and oral cavities were photographed and assessed. Grey/distal banded nails and/or oral pigmentation were significantly associated with a CD4 cell count <200 cells/microl (P < 0.001), with a sensitivity of 66%, a specificity of 50% and a negative predictive value of 77%. However, there was no association when a CD4 cell count cut-off of <350 cells/microl was used. Inter-observer agreement (k 0.46) was fair/moderate. CONCLUSIONS While grey/distal banded nails and/or oral pigmentation are associated with low CD4 counts, the sensitivity and kappa score are too low for this method to be recommended as a tool to guide ART initiation; large number of individuals eligible for ART would be missed.

Abstract
Mucocutaneous findings in 150 HIV+ve cases (F, 79; M, 71) were evaluated over a one-year period. Mucocutaneous manifestations were seen in 96% with 2.9 mean number of dermatoses and mean cluster of differentiation (CD4) count of 196.33 cells/mm3. The highest number of mean dermatoses, 3.29, was seen in individuals with severe immunosuppression. The most common mucocutaneous manifestation seen was candidiasis (35.33%), followed by seborrhoeic dermatitis (31.33%), oral pigmentation (29.33%), xerosis/ichthyosis (22.67%), pyodermas (22%), periodontitis (17.33%) and nail pigmentation (16.67%). Patient stratification according to the WHO immunological staging, according to CD4 counts, showed a statistically significant association ( P < 0.05) for candidiasis, scabies, paronychia, oral pigmentation and diffuse hair loss. Nail and oral pigmentary changes, trichomegaly and subcutaneous fungal infections caused by dermatophytes were highlights of the study. Incidences of xerosis/ichthyosis, pyodermas, scabies and molluscum contagiosum reported in our study were higher and pruritic popular eruptions was lower than those in previous Indian studies. Cutaneous neoplasms were not seen in the present study.

Abstract
BACKGROUND Herpes zoster (HZ) infection of the trigeminal nerve is associated with complications such as postherpetic neuralgia, facial scarring, loss of hearing ability and conjunctivitis. Until 2005, postherpetic alveolar necrosis and spontaneous tooth exfoliation have been described in 20 cases unrelated to HIV infection. OBJECTIVE The aim of this study was to describe HIV infection in patients (two women, two men, average age 30 years) who suffered from HZ attacks to their trigeminal nerves. MAIN OUTCOME MEASURES None of the patients had received antiherpetic medications or antiretroviral therapy. HIV infection was only diagnosed after the development of HZ. Facial scarring with depigmentation and hyperesthesia (postherpetic neuralgia) was diagnosed in all four patients. Oral findings consisted of spontaneous loss of both maxillary or mandibular teeth. Osteonecrosis of varying extent was also found. Treatment consisted of extractions of teeth and administration of antibiotics and analgesics. Healing of alveolar wounds was unremarkable. CONCLUSION Complications affecting the alveolar bone and teeth seem to be rare in HIV-infected patients.

Abstract
Acokanthera schimperi (Apocynaceae), Euclea schimperi (Ebenaceae), Inula confertiflora (Asteraceae), Melilotus elegans (Leguminosae), and Plumbago zeylanica (Plumbaginaceae), are some of the medicinal plants used in Ethiopia for treatment of various skin disorders. In this study, the antiviral activities of the 80% methanolic extracts of these plants have been examined against coxsackievirus B3 (CVB3), influenza A virus and herpes simplex virus type1 Kupka (HSV-1) using cytopathic effect (CPE) inhibitory assays in HeLa, MDCK, and GMK cells, respectively. In parallel, the cytotoxicity was quantified using a crystal violet uptake assay. The antiviral activity of the most active compound was confirmed with plaque reduction assays. The results revealed that the extracts of Acokanthera schimperi and Euclea schimperi showed antiviral activity against all three tested viruses albeit with unequal efficacy. Whereas the Acokanthera schimperi extract exhibited the strongest activity against CVB3, the extract of Euclea schimperi inhibited influenzavirus A replication most effectively. A weak anti-influenzavirus A activity was also exhibited by the other plant extracts tested. In addition, CVB3 was inhibited by the extracts of Plumbago zeylanica and HSV-1 by Inula confertiflora. Thus, the extracts of these plants, particularly those of Acokanthera schimperi, Euclea schimperi and Inula confertiflora which showed activity against CVB3 and HSV-1 support their traditional use in the treatment of skin diseases of viral origin.

Abstract
BACKGROUND Dermatological manifestations are seen at every stage of HIV/AIDS (human immunodeficiency virus), and are often the presenting features. These manifestations not only act as markers but also reflect the underlying immune status. OBJECTIVE To establish skin diseases as clinical indicators of underlying immune status in HIV disease by estimating and correlating with the CD(4), CD(4) : CD(8) ratio. MATERIALS AND METHODS The CD(4), CD(8), CD(4) : CD(8) ratios were estimated using the fluorescence activated cell sorter (FACS) count system in 20 asymptomatic HIV patients, 80 HIV patients with various skin manifestations and 72 healthy volunteers as the control group. RESULTS In comparison with the CD(4) cell count of the control group (mean 885/mm(3), standard deviation 331), that of the HIV-positive individuals (mean 409.83/mm(3), standard deviation 263.07) was statistically correlated with low counts (z = 10.099 and P < 0.05). Similarly there was statistical significance with the CD(4) : CD(8) ratio among these two groups. In comparison with the CD(4) cell count of the asymptomatic HIV-positive individuals (mean 620.65/mm(3) and standard deviation 262.065), the CD(4) cell count of the HIV-positive patients with various dermatological manifestations (mean 357.15/mm(3), standard deviation 236.95) was statistically correlated with low counts (z = 4.0978 and P < 0.05). Similarly there was statistical significance with the CD(4) : CD(8) ratio among these two groups. CONCLUSIONS There was an inverse relation between the CD(4) counts and the incidence and severity of skin diseases in the HIV/AIDS patients. Cutaneous manifestations of HIV can be considered as good clinical indicators to predict and access the underlying immune status in resource-poor countries.

Abstract
Oral mucosa is one of the first barriers to the outside world which encounters various antigens, microorganisms and physical agents. Numerous oral pathologies challenge the dermatologists. Some may be the first sign of an underlying immunosuppression, while others are the inevitable serious outcomes of long-lasting mucosal disease. The differential diagnosis is crucial in terms of prompt and effective treatment.

Abstract
Although human immundeficiency virus (HIV) infection is endemic in Southeast Asia, data on oral mycotic flora in this disease in Asians are sparse. The aim of this study was to determine the prevalence of Candida species in HIV-infected Cambodians with oral candidosis, unexposed (group 1) and exposed to antimycotics (group 2) and a healthy population (group 3). In 161 HIV patients with oral candidosis (group 1: 121 pts; group 2: 40 pts) and in 81 controls (group 3) swab samples of tongue and palate were obtained. Oral candidosis was detected in 100 and 70% of groups 1 and 2 respectively. Candida spp. were isolated from 91 and 100% of groups 1 and 2, respectively, and from 79% of controls. Candida albicans was the most common, with non-albicans species such as C. tropicalis and C. krusei being notable. Our data indicate that variants of oral candidal infections in HIV disease are similar to those seen in the pre-HAART era. The particularly high rate of C. krusei isolation in all groups is noteworthy.

Abstract
OBJETIVO: Correlacionar a prevalência das doenças dermatológicas entre pacientes infectados pelo HIV com a contagem de linfócitos CD4. MÉTODOS: Estudo de série de casos realizado na região de Caxias do Sul, Estado do Rio Grande do Sul. Os dados foram coletados por meio da revisão de prontuários de pacientes com infecção pelo HIV internados em hospital público (198 pacientes, período de março de 1998 a junho de 2002) ou atendidos no ambulatório central universitário (40 pacientes, período de março a junho de 2002). As variáveis analisadas foram: idade, sexo, contagem de linfócitos CD4, carga viral e doenças dermatológicas apresentadas pelo paciente. Os testes estatísticos utilizados foram o Teste t de Student, o de Spearman e o do qui-quadrado. RESULTADOS: A freqüência de doença dermatológica foi de 67,2% entre os pacientes hospitalizados e de 75,0% entre os pacientes ambulatoriais. Candidíase oral foi a doença dermatológica mais prevalente. Na população hospitalar, a média de células CD4 foi menor entre os pacientes com doença dermatológica dos sem doença dermatológica (142,34 células/mm³ vs 512,35 células/mm³, respectivamente; p=0,018). O mesmo fenômeno foi observado na população ambulatorial (138,88 células/mm³ e 336,21 células/mm³, respectivamente; p=0,001). Verificou-se, em ambas as populações, uma correlação negativa entre a contagem de CD4 e o número total de doenças dermatológicas apresentadas pelo paciente (p=0,000, população hospitalar; p=0,000, população ambulatorial). CONCLUSÕES: As doenças dermatológicas são altamente prevalentes entre os pacientes infectados pelo HIV, sendo que a freqüência e o número dessas manifestações correlacionam-se bem com o status imunológico do paciente e com a progressão da doença.

Abstract
Despite the development of laboratory methods, dermatological symptoms are a basic index of the presence and physical course of HIV infection. HIV infection usually undergoes a long latent period, proceeds to a period of immunodeficiency-related symptoms, and ends in an advanced immunodeficiency state characterized by opportunistic infections and neoplasms. Occasionally, dermatological manifestations can be the first signs of asymptomatic disease, indices of advanced immunodeficiency, or symptoms of opportunistic infections or neoplasms. The variety of symptoms and signs for the skin during the course of HIV infection is a consequence of the progressing immunodeficiency and therefore indicates the underlying disorder. The use of these manifestations is a challenge for clinical praxis.

Abstract
Cutaneous manifestations are common and often the presenting feature of human immunodeficiency virus (HIV) infection, but a comprehensive study of HIV-associated skin lesions is not available in Taiwan. We reviewed all skin lesions in all HIV patients diagnosed in our department between 1990 and 1998 to document the spectrum of skin manifestations, the frequency of each disorder, and their relationship with CD4 counts. A total of 64 HIV patients were studied, including 38 with acquired immunodeficiency syndrome (AIDS) (CD4 < 200 x 10(6) cells/L) and 26 who had not developed AIDS (non-AIDS). There were 142 episodes of skin conditions representing 25 different skin diseases, including oral candidiasis (15% in non-AIDS vs 71% in AIDS patients), drug eruptions, herpes simplex, seborrheic dermatitis, dermatophytosis, herpes zoster, secondary syphilis, condyloma acuminatum, Kaposi's sarcoma (16% among AIDS patients), hairy leukoplakia, and molluscum contagiosum (13% among AIDS patients), in decreasing order. Several unusual cases are briefly described, including verrucous herpes infection, condyloma-like molluscum contagiosum, and AIDS-associated pigmented erythroderma. In our study, 70% of all HIV patients had skin diseases, with an average of 2.2 conditions per patient (3.2 in AIDS patients vs 0.7 in non-AIDS patients; p < 0.001). A broad spectrum of HIV-associated skin diseases was observed in our series. The frequency of HIV-associated skin disease was 92% in AIDS patients and 39% in non-AIDS patients; 78% of skin lesions in AIDS patients were diagnosed when CD4 counts were below 100 x 10(6) cells/L.

Abstract
A síndrome da imunodeficiência adquirida foi reconhecida pela primeira vez como nova doença em 1981 devido à associação atípica de sarcoma de Kaposi e pneumonia por Pneumocystis carinii em homens. A pele é sede freqüente de doenças conseqüentes a essa infecção. A psoríase é dermatose crônica que afeta proporção que varia de 1,3 a 5% dos pacientes infectados com HIV. Portadores de psoríase que apresentem formas clínicas exacerbadas e dificuldade de resposta terapêutica devem ser investigados para possível infecção pelo HIV. É relatado caso de paciente do sexo masculino, de 44 anos, que iniciou com lesões eritêmato-escamosas no couro cabeludo, nos cotovelos, joelhos, palma das mãos, planta dos pés, além de comprometimento ungueal, após infecção pelo HIV. Confirmado o diagnóstico de psoríase e introduzida a terapia anti-retroviral, houve melhora significativa das lesões.

Abstract
There are currently over 34 million people worldwide infected with human immunodeficiency virus (HIV) with 15,000 new patients infected each day. The acquired immunodefiency syndrome (AIDS) pandemic has particularly affected the third world and currently over 70% of those infected reside in sub-Saharan Africa. The epicenter of the pandemic is shifting to Asia as HIV infection increases in the densely populated countries of India, China, and SE Asia. Patients with HIV infection develop a variety of mucocutaneous diseases and often present to dermatologists.

Abstract
BACKGROUND Patients who are human immunodeficiency virus (HIV) positive are predisposed to the development of infections including tinea pedis and onychomycosis. While smaller studies have been reported, there has been no large study evaluating the prevalence of onychomycosis in HIV-positive individuals, or comparing the development of onychomycosis in a typical temperate area with that in a typical tropical area. METHODS HIV-positive individuals were evaluated at five clinics: four in Ontario, Canada and one in Sao Paulo, Brazil. The subjects were asked questions to determine the epidemiology of onychomycosis in HIV-positive individuals. The feet were examined and nail material was obtained for mycologic examination to determine the causative organism of onychomycosis. RESULTS A total of 500 subjects were examined (415 men and 85 women; age (mean +/- SE), 39 +/- 0.4 years; 400 Canadian, 100 Brazilian). The racial origins of the Canadian patients were: Caucasian, 83.8%; Asian, 4.3%; African-American, 8.1%; Hispanic, 3.3%; American Indian, 0.3%. The Brazilian origins were: Caucasian, 68.7%; African, 18.1%; mixed race, 13.3%. Abnormal appearing nails and mycologic evidence of onychomycosis were present in 200 (40.0%) and 116 (23.2%), respectively, of 500 subjects. The prevalence of onychomycosis in the Canadian and Brazilian samples was 24.0% (96 of 400) and 20.0% (20 of 100), respectively. The projected prevalence of onychomycosis in HIV-positive individuals in Canada was 19.9% (95% CI: 16.0-23.9%) after taking into account the age and sex distribution of HIV-positive individuals in the population. When nails appeared clinically abnormal, the prevalence of onychomycosis was 50.5% (Canada, 51.3%; Brazil, 45.5%). For comparison, published data indicate that the prevalence of onychomycosis in immunocompetent individuals living in Canada is 6.9%. The clinical presentation of onychomycosis for the whole sample (n=500) was: distal and lateral subungual onychomycosis (DLSO), 20.0%; white superficial onychomycosis (WSO), 3.6%; proximal subungual onychomycosis (PSO), 1.8% (Canadian and Brazilian samples: DLSO 21.2% vs. 15.0%, WSO 3.3% vs. 5.0%, and PSO 1.5% vs. 3.0%). The distribution of the causative fungal organisms was: dermatophytes: Candida species: nondermatophyte molds, 73:2:2 (Canadian and Brazilian samples: dermatophytes 95.5% vs. 90.9%, Candida species 3.0% vs. 0%, and nondermatophyte molds 1.5% vs. 9.0%). The use of protease inhibitors, reverse transcriptase inhibitors, or oral antifungal agents did not make a significant difference in the prevalence of onychomycosis for both the Canadian and Brazilian groups. Patients with onychomycosis were aware of their abnormal appearing nails (chi2(1)=69.7, P<0.001), embarrassed by the appearance of their nails (chi2(1)=29.7, P<0.001), and took measures to hide their nails from other individuals. A higher proportion of individuals with onychomycosis experienced discomfort compared with those without the disease (chi2(1)=9.0, P=0.003). Also, individuals who experienced pain in the nail unit were more likely to have onychomycosis (risk odds ratio (ROR), 2.2; 95% CI: 1.0-4.7, P=0.05). CONCLUSIONS The prevalence of onychomycosis in HIV-positive individuals in the sample of 500 patients was 23.2%. In the Canadian (n=400) and Brazilian (n=100) samples, the corresponding figures were 24% and 20%, respectively, with the predominant causative organisms being dermatophytes. The projected prevalence of onychomycosis in HIV-positive Canadians is 19.9%. Predisposing factors include a CD4 count of approximately 370, a positive family history of onychomycosis, a history of tinea pedis, and walking barefoot around pools. Onychomycosis can be symptomatic, a source of embarrassment, and a potential cause of morbidity.

Abstract
Articles included in this review reflect the recent advances made in basic research and the clinical management of psoriatic arthritis in 1999. Some of these advances are destined to modify the current approach to the disease. The problems related to nosology and epidemiology, the two still controversial aspects, are discussed first. Genetic susceptibility to psoriasis and psoriatic arthritis, and the inciting role played by some bacteria, are confirmed, and attention is focused on the role of T cells, cytokines, adhesion molecules, and angiogenetic factors in the skin and synovial membrane. New classification criteria are provided and a simplified spectrum of the disease seems to emerge from clinical studies. Modern imaging techniques enable early articular changes to be discovered, support innovative pathogenetic hypotheses, and allow new therapeutic approaches.
