[Skin manifestations in HIV infection].

In HIV-infections, skin manifestations are manifold and are conditioned mainly by the immunodeficiency. Kaposi's sarcoma, oral hairy leucoplakia and candidiasis of the esophagus are of diagnostic significance as same as a severe course of opportunistic infections e.g. herpes simplex, herpes zooster, cryptococcosis, dermatomycoses, verrucae vulgares, condylomata acuminata and others. Sometimes skin manifestations are the first perceivable sign of an HIV-infection.

Impaired T-lymphocyte-dependent immune responses to microbial antigens in patients with HIV-1-associated persistent generalized lymphadenopathy.

T-cell mediated and humoral responses directed to microbial antigens were investigated, at the time of the initial visit, in a group of 139 patients with HIV-1-related persistent generalized lymphadenopathy (PGL) enrolled in a longitudinal study. In vivo and in vitro cell-mediated responses to tuberculin were lower in patients than in controls. Differences were not significant for candidin and streptococcal antigen in vitro, whereas higher responses were observed in the patient group for cytomegalovirus antigen. Following immunization, a subgroup of patients did not have a significantly raised serum antitetanus antibody level, whereas in vitro lymphocyte proliferative responses to tetanus toxoid were lower than in controls. No association was found between these abnormalities and other immunological parameters, including the blood level of CD4+ lymphocytes. Lower responses to most microbial antigens were observed in patients with HIV-1-related symptoms in addition to lymphadenopathy, or the patients who progressed to AIDS in the 2 years following the study. Moreover, intravenous drug users showed higher responses than homosexual patients, possibly because of the influence of previous infections on immunological responses to microbial antigens.

Cutaneous and plasma values of von Willebrand factor in AIDS: a marker of endothelial stimulation?

Patients infected by the human immunodeficiency virus (HIV) represent a model in which endothelial proliferation and/or damage are of concern. We studied Von Willebrand factor (VWF) plasma values as a presumed marker of endothelial proliferation in patients with the lymphadenopathy syndrome (LAS) (n = 45), AIDS-related Kaposi's sarcoma (KS) (n = 23), and AIDS opportunistic infections (n = 9), in comparison with normal controls (n = 19) and classical KS (n = 12). VWF was increased in AIDS patients with KS (p less than 10(-6)), in AIDS patients without KS (p less than 10(-7)), and to a lesser extent in classical KS (p less than 10(-3)) and LAS (p less than 10(-2] patients. To evaluate the diffusion of the vascular proliferation in HIV-infected patients, we studied the number of vessels within the superficial dermis of clinically uninvolved skin by an indirect immunoperoxidase method. We used an antibody directed against VWF in skin biopsies from 20 LAS patients and 10 AIDS-related KS patients compared to 11 controls and 10 classical KS patients. An increase in the number of blood vessels in normal skin was found in LAS (p less than 10(-2)), classical KS (p less than 0.05), and AIDS-related KS (p less than 10(-2]. Statistical studies and comparisons between plasma and cutaneous values of VWF indicate that plasma VWF is a good marker of endothelial damage but a poor marker of vascular proliferation in HIV-infected patients.

Malignant acanthosis nigricans associated with non-Hodgkin's lymphoma. Report of 2 cases.

Two cases of malignant acanthosis nigricans associated with non-Hodgkin's lymphoma are presented. A 61-year-old negro male with a diffuse large cell non-Hodgkin's lymphoma presented extensive acanthosis nigricans, pachydermatoglyphy and florid cutaneous papillomatosis. No viral particles were observed by electron microscopic studies of the wart-like lesions. Acanthosis nigricans disappeared under chemotherapy. The second case was a 21-year-old caucasian male with non T non B diffuse large cell non-Hodgkin's lymphoma. Very few cases of acanthosis nigricans associated with non-Hodgkin's lymphoma have been reported in the literature, since to our knowledge these two are only the fourth and fifth. Pachydermatoglyphy and florid cutaneous papillomatosis are markers of malignant acanthosis nigricans.

[Kaposi's disease in AIDS: 31 cases].

We report 31 cases of AIDS-Kaposi's sarcoma (KS) studied at the Hôpital Saint-Louis, Paris, France, from January 1983 to January 1986. Twenty-nine cases were cutaneous KS and 2 were lymph-node KS. Twenty-eight patients were homosexual or bisexual males, 1 was a woman with transfusion-AIDS and 1 was an intravenous drug-addict; one male had no known risk factor. Thirty were male and 1 female, mean age 35.5 years (+/- 8.4). All were Caucasian and positive for LAV antibodies (Elavia). 17/30 (56.6 p. 100) had a history of syphilis, 16/30 (53.3 p. 100) had a positive TPHA test, 12/30 (40 p. 100) had a history of urethral discharge, 26/31 (87 p. 100) had a history of sexually transmitted disease. 27/30 had antibodies against HBs or HBc. 14/31 (45 p. 100) presented with mild symptoms (fever, loss of weight). 10/28 (36 p. 100) had lymph node enlargement before the first cutaneous lesions of KS developed. Initial involvement included the trunk (32 p. 100), the legs (25 p. 100), the face (21 p. 100) and the lower limbs (11 p. 100). Seventy-one p. 100 of the patients had more than 10 lesions at the initial assessment. The palate was involved in 50 p. 100 of patients, the lymph nodes in 74 p. 100, the stomach in 38 p. 100, the colon in 31 p. 100. In 8 cases pulmonary involvement was present. Altogether, 55 p. 100 of the patients had visceral involvement. Enlargement of the spleen (16 p. 100) and liver (13 p. 100) was also noted. Nineteen p. 100 of the patients had chronic dermatophytic cutaneous infection, 39 p. 100 had oral candidiasis, 32 p. 100 had seborrheic dermatitis, 6 p. 100 had oral hairy leukoplakia and 26 p. 100 had trimethoprim-sulfamethoxazole eruption. Fifty-five p. 100 developed opportunistic infection (OI) (Pneumocystis carinii 8 cases, intestinal cryptosporidiosis 6 cases, cerebral toxoplasmosis 4 cases, CMV pulmonary infection 3 cases). In 14 cases KS preceded OI and in 3 cases OI preceded KS. Biological results are shown in tables II and III. Main findings were: mild inflammatory syndrome (ESR 33 +/- 24 mm, first hour), polyclonal hypergammaglobulinemia (18.6 g/l +/- 5.8), elevation of plasma factor VIII related antigen (191 +/- 66 U/dl), elevation of serum activity of angiotensin-converting enzyme (23.8 +/- 5 nmol/ml/min), low plasmatic cholesterol (3.77 +/- 1.1 mmol/l).(ABSTRACT TRUNCATED AT 400 WORDS)

[Early manifestations of neuromeningeal syphilis. Review of the literature apropos of 3 severe forms].

We report 3 cases of severe syphilitic neuro-meningitis during the secondary stage: acute transverse dorsal myelitis with permanent paraplegia in a 17 year old teenager (case no. 1), uveo-meningitis with intracranial hypertension and diminished vision in a 52 year old woman (case no. 2), lower medulla lesion in a 46 year old man (case no. 3). The diagnosis was based upon highly positive serological tests for syphilis, associated with a compatible clinical context and meningitis in CSF specimens. Treatment was successful in cases nos. 2 and 3, unsuccessful in case no. 1 due to the irreversible character of the medullar lesions. Based on these 3 cases, the following points are discussed: the relatively atypical clinical character in the current context, the difficulties of the diagnosis, and the treatment regimens recommended for neurological syphilis. Despite the rarity of such cases, their extreme severity early in the secondary stage strongly implies the necessity for prevention by detecting and treating early syphilis. Attention is drawn upon the importance of doing serological tests for syphilis when presented with any atypical neurological situation.

[Digital tenosynovitis caused by non-tuberculous mycobacteria. Apropos of the 4th case caused by Mycobacterium terrae].

A 75 year old man developed chronic flexor tenosynovitis in a finger, caused by Mycobacterium terrae. He had a history of diabetes mellitus and arteritis, but not of local trauma. However, triamcinolone had been injected into the tendon sheath on 3 occasions. Chemotherapy was instituted, but after 3 months amputation became mandatory. This is the fourth case reported in which M. terrae was involved, and it supports the responsibility of this organism as a human pathogen. Attention is drawn to the hazards of corticosteroid injections into tendon sheaths.
