To investigate the impact of HIV infection on the prevalence, incidence and short-term prognosis of squamous intraepithelial lesions (SIL), in a prospective study with 1-year follow-up.
Between 1993 ...and 1995, 271 HIV-positive and 171 HIV-negative women at high risk of HIV infection were recruited, 365 (82.6%) of whom completed the 1-year follow-up. The women underwent a Papanicolaou smear test at inclusion and at 6 and 12 months. Human papillomavirus (HPV) was detected at inclusion by Southern blot and PCR.
The SIL prevalence ranged from 7.5% for HIV-negative to 31.3% for HIV-positive women with CD4 cell counts < 500 x 10(6)/l (P < 0.001). Other factors associated independently and significantly with SIL prevalence were HPV-16, 18, 33 and related types, HPV-31, -35, -39 and related types, lifetime number of partners, younger age, past history of SIL and lack of past cervical screening. The SIL incidence ranged from 4.9% in HIV-negative women to 27% in HIV-positive women with CD4 cells < 500 x 10(6)/l (P < 0.001). Progression from low- to high-grade SIL during follow-up was detected in 38.1% of HIV-positive women with CD4 cells < or = 500 x 10(6)/l but in no HIV-negative nor HIV-positive women with CD4 cells > 500 x 10(6)/l. HPV-16, 18, 33 and related types were also associated with higher incidence of SIL and progression from low- to high-grade SIL.
HIV-induced immunodeficiency is associated with high prevalence, incidence and persistence/progression of SIL. A pejorative influence of HIV infection without marked immunodeficiency is less clear. HIV-positive women with SIL may thus benefit from early treatment when a useful immune response is still present.
A follow-up study of 219 patients infected with parasitologically confirmed cutaneous leishmaniasis in French Guiana was made between 1981 and 1987. Cutaneous leishmaniasis appeared to be common in ...young male adults entering the forest for professional activities (84.2% of the cases). The lesions were generally of the classical ulcerative type. They were limited to the skin and preferentially located on the legs and forearms (20.7% and 19.8% respectively). Most of the cases (86.6%) represented primary infections, but 6.8% had a recurrent lesion at the site of an old, previously cured lesion.
Kaposi's-sarcoma-associated herpesvirus(KSHV)/human-herpes-virus-8(HHV-8) sequences originally detected in AIDS-associated Kaposi's sarcoma have been found in almost every KS tested, whether endemic, ...classic, iatrogenic or epidemic. Most of the studies on African KS involved East African patients. We report herewith the study of 17 African or Guyanan KS patients, 3 with epidemic KS (EKS) from Central African Republic, 3 from Senegal (2 EKS and 1 endemic KS), 3 EKS from Cameroon and 8 from French Guiana (3 EKS and 5 endemic KS). Serum-specific antibodies directed against latent and/or lytic HHV-8 antigens were present in 16 of them (94%), detected either by immunofluorescence assay and/or by immunoperoxidase. Polymerase chain reaction (PCR), using specific primers for HHV-8 ORF26 (233 bp) and ORF75 (601 bp), was carried out on DNA extracted from KS cutaneous biopsies, clinically uninvolved skin biopsies and peripheral-blood mononuclear cells (PBMC). HHV-8 DNA was detected in 16 out of 16 (100%) KS biopsies, regardless of their origin or clinico-pathological sub-type, in 7 out of 15 (47%) normal skin samples and 7 out of 16 (44%) PBMC. Comparative PCR, carried out in 7 patients, regularly found a much higher viral load in KS biopsies than in autologous normal skin and PBMC samples. Sequencing of fragments of the ORF26 and of the ORF75 demonstrated that the 16 HHV-8 strains were of the A, B or C sub-type. Furthermore, sequences of the entire ORF K1 of 4 strains showed that these HHV-8 strains of African origin were of the A5 or the B sub-type.

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.

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.
