Avascular necrosis of bone in patients with human immunodeficiency virus infection: report of 6 cases and review of the literature.

In 1998 and 1999, we diagnosed avascular necrosis of bone in 6 patients in our human immunodeficiency virus clinic practice, an incidence of 0.45%, which is 45 times greater than would be expected in the general population. Antiphospholipid antibodies and hyperlipidemia secondary to protease inhibitor therapy have been implicated as possible etiologies; however, these abnormalities cannot explain all cases of avascular necrosis of bone reported in patients with human immunodeficiency virus infection.

Nucleotide sequence, genome organisation and phylogenetic analysis of Indian citrus ringspot virus. Brief report.

The sequence of the single-stranded RNA genome of Indian citrus ringspot virus (ICRSV) consists of 7560 nucleotides. It contains six open reading frames (ORFs) which encode putative proteins of 187.3, 25, 12, 6.4, 34 and 23 kDa respectively. ORF1 encodes a polypeptide that contains all the elements of a replicase; ORFs 2, 3 and 4 compose a triple-gene block; ORF5 encodes the capsid protein; the function of ORF6 is unknown. Phylogenetic analysis of the complete genome and each ORF separately, and database searches indicate that ICRSV, though showing some similarities to potexviruses, is significantly different, as in the presence of ORF6, the genome and CP sizes, and particle morphology. These differences favour its inclusion in a new virus genus.

Tuberculous pancreatic abscess as an initial AIDS-defining disorder in a patient infected with the human immunodeficiency virus: case report and review.

Tuberculosis (TB) is the most common opportunistic infection worldwide in human immunodeficiency virus (HIV)-infected patients. Intraabdominal TB includes lymphadenopathy and focal lesions of solid viscera. Symptomatic expression of tuberculous invasion of the pancreas (supplemented by demonstration of a mass on imaging) is rare among HIV-infected patients. We report the case of an HIV-infected patient with a tuberculous pancreatic abscess and review nine similar cases. All patients presented with persistent fever and abdominal pain. The diagnosis was made on the basis of detection of pancreatic mass lesions on computed tomographic (CT) scans and the results of cultures and/or acid-fast stains of peripancreatic abscess material and/or other body fluids. Despite an excellent response to antituberculous therapy, three patients died of unrelated causes. In the setting of a febrile illness with abdominal symptoms, tuberculous pancreatic abscess should be considered in the differential diagnosis for HIV-infected patients with a CT-identified mass lesion.

Congenital herpes simplex virus infections. Report of three cases and review of the literature.

Three infants with congenital herpes simplex virus infection were examined and treated. One demonstrated findings of individual vesicles on an erythematous base; another had pustules. The children were treated with vidarabine intravenously. Two of the three survived. The literature suggests a potential increase in the occurrence of this infection in neonates. Since the dermatologist is often asked to aid in the diagnosis of this entity and early recognition is vital, it is important to be familiar with the possible causes of vesicopustular lesions, as well as the epidemiology, clinical manifestations, pathogenesis, and current forms of treatment of congenital herpes simplex virus infections.

Lues maligna, or ulceronodular syphilis, in a man infected with human immunodeficiency virus: case report and review.

A 30-year-old bisexual man who was infected with human immunodeficiency virus (HIV) and had a history of anaphylaxis to penicillin developed lues maligna, or ulceronodular secondary syphilis. Therapy with parenteral erythromycin failed, and he was subsequently treated with ceftriaxone following penicillin desensitization. A review of the English-language literature identified 14 cases of lues maligna reported between the early 1900s and 1988. From 1989 to 1994, an additional 12 cases (including the current case) were reported. Of those 12 cases, 11 occurred in patients who either were infected with HIV or were at high risk for HIV infection. Patients infected with HIV may be at increased risk of developing this severe form of secondary syphilis. Lues maligna should be considered in the differential diagnosis of HIV-infected patients who present with ulceronodular lesions.

Rhodococcus equi pneumonia in a patient with human immunodeficiency virus: case report and review.

Rhodococcus equi is a facultative, intracellular, gram-positive coccobacillus increasingly reported as an opportunistic pathogen in patients positive for human immunodeficiency virus (HIV). An HIV-positive man developed R. equi pneumonia and sepsis. He failed to improve despite surgical drainage of localized infection and many empiric antibiotics. Time-kill studies of R. equi isolated from the patient were performed against various antimicrobial agents to optimize therapy. Levofloxacin seemed to offer excellent in vitro bactericidal activity. Antagonism was observed with certain antibiotic combinations. Our anecdotal case report suggests that fluoroquinolones such as levofloxacin may offer superior efficacy to standard therapy in rhodococcal infections; their clinical utility deserves further investigation. In view of potential antagonism, prospective susceptibility testing for various drugs and drug combinations should be considered when clinically indicated.

[Liver tuberculous abscess in patients with human immunodeficiency virus infection: report of 2 cases and review of the literature].

Two cases are reported of hepatic tuberculous abscesses (HTBA) in patients infected with the human immunodeficiency virus (HIV), stressing the rarity of this location. Likewise, a review is made of cases reported in the literature. Our two patients presented with a prolonged febrile condition, with constitutional symptoms and nonspecific abdominal discomfort. In one patient the hepatic location was accompanied by a pulmonar location too. The course of the patients was good and symptoms subsided with tuberculostatic therapy. To note the possibility of finding hepatic tuberculous abscesses in HIV patients with prolonged fever and nonspecific abdominal pain more frequently than considered until now.

[Bronchial cancer in patients infected with human immunodeficiency virus (HIV). Report of 3 cases].

We report 3 cases of bronchial carcinoma in patients with human immunodeficiency virus (HIV) infection. Like the other 13 cases found in the literature, these were characterized by their occurrence in young subjects, their often adenocarcinomatous nature and their abnormally severe course. These clinical features raise the problem of the role played by HIV in the development and, above all, the clinical expression of bronchial carcinoma.

Pulmonary hypertension associated with human immunodeficiency virus infection. Report of two cases and review of the literature.

Recent reports have suggested a possible association between HIV-1 infection and "idiopathic" pulmonary hypertension (PH), but the pathogenetic role of the viral agent has not been fully defined yet. We report the cases of two white males positive for human immunodeficiency virus type 1 (HIV-1) who presented with clinical and hemodynamic diagnosis of pulmonary hypertension. They were heterosexual, non-hemophiliac, heroin abusers with no signs of clinical AIDS. Neither one of the patients had opportunistic lung infections or any other cause of secondary pulmonary hypertension. In one case, peculiar clinical and electrocardiographic features of PH were associated with signs of thrombotic thrombocytopenic purpura (TTP). The association between PH and HIV-1 infection might be explained by a severe alteration of pulmonary endothelial cell homeostasis secondary to HIV-1 viral infection.

Invasive Aspergillus sinusitis in patients with human immunodeficiency virus infection. Report of 2 cases and review.

Aspergillus sinusitis is an uncommon complication of advanced human immunodeficiency virus (HIV) infection. We describe 2 patients with AIDS who developed histologically proven invasive Aspergillus sinusitis. We also review the findings of 14 histologically documented and 5 probable cases of invasive Aspergillus sinusitis. The literature on the prevalence, predisposing factors, diagnosis, treatment, and prognosis of the infection is reviewed. Major risk factors for the disease are advanced AIDS, chronic sinusitis or otitis, neutropenia, use of corticosteroids and prolonged use of broad spectrum antibiotics. The most common presenting symptoms are nonspecific and include fever, local pain, and swelling. Despite the newer diagnostic and therapeutic approaches discussed herein, the infection is usually fatal in HIV-infected patients. Early diagnosis and aggressive treatment remain the only available means to improve the currently dismal prognosis of Aspergillus sinusitis.

Effect of rifamycin derivatives and coumermycin A1 on in vitro RNA synthesis by African swine fever virus. Brief report.

Several rifamycin derivatives inhibited the DNA-dependent RNA polymerase of African swine fever (ASF) virus particles. The inhibition was similar to that found with vaccinia virus RNA polymerase. Coumermycin A1, an inhibitor of type II DNA topoisomerases, inhibited strongly RNA synthesis in vitro by ASF virus particles. This suggests that transcription of ASF virus DNA requires a DNA topoisomerase.
