RESUMEN
Immune reconstitution disease (IRD) has been associated with many pathogens after the initiation of antiretroviral therapy for advanced HIV infection. A retrospective cohort study was conducted to determine whether cutaneous mycoses were also associated with IRD. After adjusting for various confounding factors, the recent initiation of HAART was found to be associated with an increased incidence of cutaneous mycoses when compared with untreated patients.

INTRODUCTION: Penicilliosis is caused by Penicillium marneffei, a dimorphic fungus endemic in southeast Asia and southern China. Since 1988, this deep mycosis has been one of the most frequent opportunistic infections in subjects with HIV infection in this region. We report the first observation of penicilliosis in Laos in a subject infected by HIV. CASE: A Laotian women with HIV infection and under treatment for tuberculosis, was hospitalized with a cough, fever and cervical lymphadenopathy. A lymph node smear stained with RAL 555 confirmed the diagnosis of penicilliosis. The histologic examination detected some Penicillium marneffei, stained by PAS and Gomori-Grocot. The patient was treated successfully with ketoconazole. DISCUSSION: Penicilliosis is endemic in southeast Asia. Especially in Thailand, it is a common opportunistic infection in HIV-infected persons. This case confirms the existence of penicilliosis in Laos, where its prevalence as an opportunistic infection is probably underestimated. The diagnostic method (slide stained with RAL 555) used in this case is simple, rapid, and appropriate for countries with limited economic resources to devote to the penicilliosis diagnosis.

We aimed to identify prognostic factors for AIDS-associated disseminated histoplasmosis. In a multivariate analysis, we found that dyspnea, a platelet count of <100,000 platelets/mm3, and lactate dehydrogenase levels of >2 times the upper limit of the normal range were significantly independently associated with the death of the patient during the first 30 days of antifungal treatment.

OBJECTIVE: To retrospectively study the incidence of chronic cutaneous lupus erythematosus (CCLE) in French Guiana (FG), South America, during the period 1995-1999. METHODS: Private and public physicians specializing in dermatology, rheumatology, and internal medicine were asked during the year 2000 about lupus cases. We reviewed hospitals' files in data-processing departments. RESULTS: Twenty new cases of CCLE, mostly discoid form, were identified during this 5-year period in this population of predominantly African descent. The average annual incidence of the disease was 2.59 per 100,000 inhabitants (95% confidence interval 1.5-4). However, our methodology could introduce underestimation of the incidence of the disease. CONCLUSION: The average annual incidence of CCLE in FG appears to be low in this retrospective study, but is very similar to the only previously published data in the US.

A retrospective cohort study was conducted to determine whether the incidence of leprosy varied with the duration of antiretroviral therapy (ART). Between 1992 and 2006, seven cases of leprosy were observed. The incidence of leprosy in untreated patients was 0.7 per 1000 person-years, 13 per 1000 person-years in persons receiving HAART for more than 3 months and 0.9 per 1000 person-years for persons receiving HAART for more than 3 months. The adjusted hazard ratio was 18.5 (95% confidence interval, 1.6-217) with P = 0.02. In tropical areas where HAART is increasingly available, physicians should be aware of the possibility of incident leprosy shortly after HAART initiation.

We report the onset of an urban epidemic of human myiasis caused by Dermatobia hominis. To our knowledge, this is the first urban epidemic described for D. hominis. The epidemic was most likely related to exceptional weather conditions and notably high rainfall in January 2000, which may have facilitated the maturation of the pupae.

Immune reconstitution after HAART initiation is often complicated by adverse clinical manifestations caused either by the unmasking of preexisting untreated opportunistic infections or the clinical deterioration of a known and treated opportunistic infection. The present study was conducted to determine whether the initiation of HAART was followed by an increase in the incidence of mucosal candidiases, a possible manifestation of immune reconstitution disease of the unmasking type.

Demodecidosis is an ectoparasitosis that is infrequently observed in subjects with human immunodeficiency virus (HIV) infection. It has a rosacea-like presentation. We present three cases in patients with acquired immunodeficiency syndrome (AIDS). Two of these patients had a profuse eruption, and all three cases were cured by ivermectin. The single-dose treatment could be repeated in cases of subsequent recurrence. Ivermectin thus seems to be a good alternative in the treatment of demodecidosis in patients with HIV infection.

BACKGROUND: Oral or cutaneous acquired immunodeficiency syndrome (AIDS)-related histoplasmosis is a rare presentation of disseminated histoplasmosis. OBJECTIVE: To describe this clinical presentation and to compare it with other forms of AIDS-related disseminated histoplasmosis. METHODS: A cross-sectional study of patients with AIDS-related disseminated histoplasmosis was performed. CD4 counts and survival were compared between patients with oral or cutaneous histoplasmosis and patients with nonmucocutaneous disseminated histoplasmosis. RESULTS: The mean CD4 lymphocyte count was lower in patients with mucocutaneous lesions than in patients with nonmucocutaneous disseminated histoplasmosis (29 vs. 72/mm3, P = 0.002). The proportion of survivors 1 month after diagnosis did not differ significantly between the two groups (13/21 vs. 32/45, P = 0.4). At 6 months, the proportion of survivors was significantly lower for patients with mucocutaneous lesions (6/21 vs. 22/39, P = 0.03). CONCLUSIONS: These results suggest that mucocutaneous lesions occur at a later stage of human immunodeficiency virus infection, but are not, in themselves, associated with a higher level of mortality. The excess mortality at 6 months reflects deaths from other complications of severe immunodepression. This study confirms the polymorphism of mucocutaneous lesions, emphasizing the need for systematic testing for Histoplasma in all cases of mucocutaneous lesions in AIDS patients.
