Abstract
The kinetoplastid protozoan Leishmania spp. cause leishmaniasis, which clinically exhibit mainly as a cutaneous, mucocutanous or visceral form depending upon the parasite species in humans. The disease is widespread geographically, leading to 20 000 annual deaths. Here, leishmaniases in both humans and animals, reservoirs and sand fly vectors on the Caribbean islands are reviewed. Autochthonous human infections by Leishmania spp. were found in the Dominican Republic, Guadeloupe and Martinique as well as Trinidad and Tobago; canine infections were found in St. Kitts and Grenada; and equine infections were found in Puerto Rico. Imported human cases have been reported in Cuba. The parasites included Leishmania amazonensis, Le. martiniquensis and Le. waltoni. Possible sand fly vectors included Lutzomyia christophei, Lu. atroclavatus, Lu. cayennensis and Lu. flaviscutellata as well as Phlebotomus guadeloupensis. Reservoirs included rats, rice rats and mouse opossum. An updated study is warranted for the control and elimination of leishmaniasis in the region because some of the data are four decades old.

Maggi RG, Krämer F. A review on the occurrence of companion vector-borne diseases in pet animals in Latin America. Parasit Vectors 2019; 12:145. [PMID: 30917860 PMCID: PMC6438007 DOI: 10.1186/s13071-019-3407-x] [Citation(s) in RCA: 64] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2019] [Accepted: 03/21/2019] [Indexed: 02/07/2023] Open
Abstract
Companion vector-borne diseases (CVBDs) are an important threat for pet life, but may also have an impact on human health, due to their often zoonotic character. The importance and awareness of CVBDs continuously increased during the last years. However, information on their occurrence is often limited in several parts of the world, which are often especially affected. Latin America (LATAM), a region with large biodiversity, is one of these regions, where information on CVBDs for pet owners, veterinarians, medical doctors and health workers is often obsolete, limited or non-existent. In the present review, a comprehensive literature search for CVBDs in companion animals (dogs and cats) was performed for several countries in Central America (Belize, Caribbean Islands, Costa Rica, Cuba, Dominican Republic, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Puerto Rico) as well as in South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, French Guiana, Guyana (British Guyana), Paraguay, Peru, Suriname, Uruguay, Venezuela) regarding the occurrence of the following parasitic and bacterial diseases: babesiosis, heartworm disease, subcutaneous dirofilariosis, hepatozoonosis, leishmaniosis, trypanosomosis, anaplasmosis, bartonellosis, borreliosis, ehrlichiosis, mycoplasmosis and rickettsiosis. An overview on the specific diseases, followed by a short summary on their occurrence per country is given. Additionally, a tabular listing on positive or non-reported occurrence is presented. None of the countries is completely free from CVBDs. The data presented in the review confirm a wide distribution of the CVBDs in focus in LATAM. This wide occurrence and the fact that most of the CVBDs can have a quite severe clinical outcome and their diagnostic as well as therapeutic options in the region are often difficult to access and to afford, demands a strong call for the prevention of pathogen transmission by the use of ectoparasiticidal and anti-feeding products as well as by performing behavioural changes.

Abstract
A recent report on the taxonomic profile of the human gut microbiome in pre-Columbian mummies (Santiago-Rodriguez et al. 2016) gives for the first time evidence of the presence of Leishmania DNA (sequences similar to Leishmania donovani according to the authors) that can be reminiscent of visceral leishmaniasis during the pre-Columbian era. It is commonly assumed that Leishmania infantum, the etiological agent of American visceral leishmaniasis (AVL) was introduced into the New World by the Iberian conquest. This finding is really surprising and must be put into perspective with what is known from an AVL epidemiological and historical point of view. Beside L. infantum, there are other species that are occasionally reported to cause AVL in the New World. Among these, L. colombiensis is present in the region of pre-Columbian mummies studied. Other explanations for these findings include a more ancient introduction of a visceral species of Leishmania from the Old World or the existence of a yet unidentified endemic species causing visceral leishmaniasis in South America. Unfortunately, very few molecular data are known about this very long pre-Columbian period concerning the circulating species of Leishmania and their diversity in America.

Abstract
Leishmanides have been rarely reported in the literature. In this study, the authors present a case of a 50-year-old HIV-positive man who developed a generalized cutaneous eruption of papules and plaques in which no microorganism was demonstrated by culture, microscopical examination, immunohistochemistry, or polymerase chain reaction. The patient was eventually diagnosed with laryngeal leishmaniasis, and when treated, the cutaneous lesions greatly improved.

Abstract
Background Co-infection of leishmaniasis and HIV is increasingly reported. The clinical presentation of leishmaniasis is determined by the host immune response to the parasite; as a consequence, this presentation will be influenced by HIV-induced immunosuppression. As leishmaniasis commonly affects the skin, increasing immunosuppression changes the clinical presentation, such as in post-kala-azar dermal leishmaniasis (PKDL) and cutaneous leishmaniasis (CL); dermal lesions are also commonly reported in visceral leishmaniasis (VL) and HIV co-infection. Methods We reviewed the literature with regard to dermal manifestations in leishmaniasis and HIV co-infection, in three clinical syndromes, according to the primary presentation: PKDL, VL, or CL. Results A wide variety of descriptions of dermal leishmaniasis in HIV co-infection has been reported. Lesions are commonly described as florid, symmetrical, non-ulcerating, nodular lesions with atypical distribution and numerous parasites. Pre-existing, unrelated dermal lesions may become parasitized. Parasites lose their tropism and no longer exclusively cause VL or CL. PKDL in HIV co-infected patients is more common and more severe and is not restricted to Leishmania donovani. In VL, dermal lesions occur in up to 18% of patients and may present as (severe) localized cutaneous leishmaniasis, disseminated cutaneous leishmaniasis (DL) or diffuse cutaneous leishmaniasis (DCL); there may be an overlap with para-kala-azar dermal leishmaniasis. In CL, dissemination in the skin may occur resembling DL or DCL; subsequent spread to the viscera may follow. Mucosal lesions are commonly found in VL or CL and HIV co-infection. Classical mucocutaneous leishmaniasis is more severe. Immune reconstitution disease (IRD) is uncommon in HIV co-infected patients with leishmaniasis on antiretroviral treatment (ART). Conclusion With increasing immunosuppression, the clinical syndromes of CL, VL, and PKDL become more severe and may overlap. These syndromes may be best described as VL with disseminated cutaneous lesions (before, during, or after VL) and disseminated cutaneous leishmaniasis with or without visceralization.

Abstract
We report the first case of visceral leishmaniasis (VL) caused by Leishmania martiniquensis in the Caribbean, which until now, was known only to cause cutaneous leishmaniasis. The disease presented with fatigue, anemia, and hepatosplenomegaly in a 61-year-old man with human immunodeficiency virus (HIV) infection who was receiving antiretroviral therapy. Diagnosis was made by bone marrow biopsy. VL is life-threatening, and its emergence in the Caribbean is of concern.

Abstract
BACKGROUND Cutaneous leishmaniasis is caused by several Leishmania species that are associated with variable outcomes before and after therapy. Optimal treatment decision is based on an accurate identification of the infecting species but current methods to type Leishmania isolates are relatively complex and/or slow. Therefore, the initial treatment decision is generally presumptive, the infecting species being suspected on epidemiological and clinical grounds. A simple method to type cultured isolates would facilitate disease management. METHODOLOGY We analyzed MALDI-TOF spectra of promastigote pellets from 46 strains cultured in monophasic medium, including 20 short-term cultured isolates from French travelers (19 with CL, 1 with VL). As per routine procedure, clinical isolates were analyzed in parallel with Multilocus Sequence Typing (MLST) at the National Reference Center for Leishmania. PRINCIPAL FINDINGS Automatic dendrogram analysis generated a classification of isolates consistent with reference determination of species based on MLST or hsp70 sequencing. A minute analysis of spectra based on a very simple, database-independent analysis of spectra based on the algorithm showed that the mutually exclusive presence of two pairs of peaks discriminated isolates considered by reference methods to belong either to the Viannia or Leishmania subgenus, and that within each subgenus presence or absence of a few peaks allowed discrimination to species complexes level. CONCLUSIONS/SIGNIFICANCE Analysis of cultured Leishmania isolates using mass spectrometry allows a rapid and simple classification to the species complex level consistent with reference methods, a potentially useful method to guide treatment decision in patients with cutaneous leishmaniasis.

Abstract
HIV/AIDS is a chronic illness, with a range of physical symptoms and psychosocial issues. The complex health and social issues associated with living with HIV mean that people living with HIV/AIDS (PLWHA) have historically often turned to complementary and alternative medicine (CAM). This article provides an overview of the literature on HIV and CAM. Databases were searched using keywords for CAM and HIV from inception to December 2012. Articles in English and in Western countries were included; letters, commentaries, news articles, articles on specific therapies and basic science studies were excluded. Of the 282 articles identified, 94 were included. Over half reported prevalence and determinants of CAM use. Lifetime use of CAM by PLWHA ranged from 30% to 90%, with national studies suggesting CAM is used by around 55% of PLWHA, practitioner-based CAM by 15%. Vitamins, herbs, and supplements were most common, followed by prayer, meditation, and spiritual approaches. CAM use was predicted by length of time since HIV diagnosis, and a greater number of medications/symptoms, with CAM often used to address limitations or problems with antiretroviral therapy. CAM users rarely rejected conventional medicine, but a number of CAM can have potentially serious side effects or interactions with ART. CAM was used as a self-management approach, providing PLWHA with an active role in their healthcare and sense of control. Clinicians, particularly nurses, should consider discussing CAM with patients as part of patient-centered care, to encourage valuable self-management and ensure patient safety.

Abstract
To date, most Leishmania and human immunodeficiency virus (HIV) coinfection cases reported to WHO come from Southern Europe. Up to the year 2001, nearly 2,000 cases of coinfection were identified, of which 90% were from Spain, Italy, France, and Portugal. However, these figures are misleading because they do not account for the large proportion of cases in many African and Asian countries that are missed due to a lack of diagnostic facilities and poor reporting systems. Most cases of coinfection in the Americas are reported in Brazil, where the incidence of leishmaniasis has spread in recent years due to overlap with major areas of HIV transmission. In some areas of Africa, the number of coinfection cases has increased dramatically due to social phenomena such as mass migration and wars. In northwest Ethiopia, up to 30% of all visceral leishmaniasis patients are also infected with HIV. In Asia, coinfections are increasingly being reported in India, which also has the highest global burden of leishmaniasis and a high rate of resistance to antimonial drugs. Based on the previous experience of 20 years of coinfection in Europe, this review focuses on the management of Leishmania-HIV-coinfected patients in low-income countries where leishmaniasis is endemic.

Abstract
BACKGROUND Leishmaniasis covers three well-individualized clinical variants, each due to individual species found in different geographic areas. Herein we report the first case of cutaneous leishmaniasis due to Leishmania major involving bone marrow in an AIDS patient in Burkina Faso. CASE REPORT A 38-year-old HIV-positive man presented with generalized, copper-coloured, painless, infiltrated, itching, papulonodular lesions present over the previous 10 months. Skin biopsy confirmed the diagnosis of diffuse cutaneous leishmaniasis. The bone-marrow smear showed numerous leishmania. The culture was positive and L. major was identified. The patient was being treated with antiretroviral medication and a pentavalent antimonial compound. The disease progression consisted of attacks and remissions separated by an average of three weeks. DISCUSSION L. major is the Leishmania species identified in Burkina Faso. It is responsible for typical cutaneous leishmaniasis but particular clinical forms have been described in immunodeficient patients, especially with diffuse cutaneous involvement. The spread of L. major infection to bone marrow could represent a public health problem in our country, where the HIV epidemic is still not under control, and particular vigilance is thus called for.

Abstract
Fevers of unknown origin have been classified as classic, nosocomial, immune-deficient, and HIV-related. More than half of the 1407 human pathogens are zoonotic, making zoonotic infections an important subcategory in each of the classifications. This article describes both common and unusual zoonoses causing fevers of unknown origin. Simian immune virus is considered as a possible emerging infection.

Abstract
Migration inhibitory factor-related protein 8 (MRP8) and MRP14 are expressed by myeloid cells and especially known as marker proteins of an immature and inflammatory subtype of macrophages. In this study, we immunohistochemically examined an accumulation of MRP8+ and MRP14+ macrophages in skin lesions during Leishmania major infection in susceptible BALB/c and RAG-2-/- mice. L. major infection caused the development of a nodular type of skin lesion at the infection site in mice and a massive accumulation of macrophages was observed in the lesions at four weeks after the infection. Immunohistochemical analyses showed MRP8+ and MRP14+ macrophages are predominant cell types in the skin lesions in both mouse strains. In contrast, F4/80+ cells, which correspond to mature macrophages, were rarely found in the skin lesions. These data suggest that the accumulation of inflammatory subtype of macrophages in BALB/c mice during L. major infection can be induced without acquired immune responses.

Abstract
BACKGROUND Few data are available on cutaneous leishmaniasis caused by dermotropic species in human immunodeficiency virus (HIV)-infected patients. OBJECTIVES To describe nine cases of cutaneous leishmaniasis in HIV+ patients and to compare their clinical features and their response to treatment with those of HIV- patients with the forms of leishmaniasis commonly found in French Guiana. METHODS A case-control study was carried out between July 1994 and December 2000 in French Guiana. We compared the following variables in nine HIV-infected patients with leishmaniasis and 27 matched controls: clinical type of leishmaniasis, number of lesions, presence of lymphangitis and adenopathy, the rate of recovery after treatment, and recurrence or reinfection. RESULTS Eight of the HIV-infected patients had localized cutaneous leishmaniasis and one had mucocutaneous leishmaniasis. All of the controls had localized cutaneous leishmaniasis. Leishmania guyanensis was the only species isolated from HIV-infected subjects. HIV-Leishmania coinfected patients had a higher rate of recurrence or reinfection (P < 0.02) and a lower rate of recovery after one treatment cycle with pentamidine (P < 0.02) than did HIV- subjects. The CD4+ lymphocyte counts exceeded 200 mm(-3) in all HIV+ patients at the time of the diagnosis with leishmaniasis. CONCLUSIONS In French Guiana, cutaneous leishmaniasis in moderately immunosuppressed HIV-infected subjects (> 200 CD4+ T cells mm(-3)) is characterized by a higher rate of recurrence or reinfection and is more difficult to treat than that in HIV- subjects.

Abstract
The biological behavior of Leishmania amazonensis in the mammalian host is highly variable, resulting in local to diffuse cutaneous lesions that sometimes metastasize. Inflammation and, more specifically, CD4+ T cells have been shown to enhance metastases in mice infected with L. amazonensis, suggesting that the process may be lymphocyte mediated. However, we document, in this study, the development of multiple cutaneous metastases in C3H SCID mice infected with L. amazonensis. This shows that functional T and B cells are not required for metastases to occur.

Abstract
Leishmania species can cause a wide spectrum of cutaneous disease in HIV-positive patients: asymptomatic, localized cutaneous, mucosal, muco-cutaneous, diffuse cutaneous or post-kala-azar leishmaniasis. In such cases, which are usually severely immunocompromised, the leishmanial parasites reach the skin of the human host by dissemination after either a new infection (resulting from the bite of infected sandfly or, probably, the sharing of contaminated syringes by intravenous-drug users) or the re-activation of a latent infection. Recent experience and past observations on the dermatology of leishmaniasis in those with Leishmania/HIV co-infection are reviewed here.

Abstract
OBJECTIVES This study examined the influence of sociodemographic, clinical, and attitudinal variables on the use of alternative therapists by people in care for HIV. METHODS Bivariate and multivariate analyses of baseline data from the nationally representative HIV Cost and Services Utilization Study were conducted. RESULTS Overall, 15.4% had used an alternative therapist, and among users, 53.9% had fewer than 5 visits in the past 6 months. Use was higher for people who were gay/lesbian, had incomes above 40,000 dollars, lived in the Northeast and West, were depressed, and wanted more information about and more decisionmaking involvement in their care. Among users, number of visits was associated with age, education, sexual orientation, insurance status, and CD4 count. CONCLUSIONS Among people receiving medical care for HIV, use of complementary care provided by alternative therapists is associated with several sociodemographic, clinical, and attitudinal variables. Evaluation of the coordination of provider-based alternative and standard medical care is needed.

Abstract
Little is known about complementary and alternative medicine (CAM) use in Canadian patients with HIV. We sought to determine the prevalence of CAM use by patients attending HIV outpatient clinics in Ontario, Canada, and to compare the characteristics of users and nonusers. Impact of CAM definition on reported utilization rates was also assessed, specifically in relation to the inclusion and exclusion of vitamins, minerals, and multivitamins in CAM definition. In-person interviews were conducted between 1999 and 2001 with 104 HIV-positive outpatients enrolled in the HIV Ontario Observational Database project (HOOD) and attending HIV outpatient clinics in Ontario. Self-reported CAM utilization and demographic data were collected. Clinical data were obtained from medical chart review. Seventy-seven percent of participants reported current CAM use. Inclusion of vitamins and minerals (CAMVIT) increased this estimate to 89%. Nearly all patients used CAM in conjunction with antiretroviral medications. Out of pocket costs ranged from CAD$0 to more than CAD$250 per month. Most patients reported CAM use was beneficial and had improved their overall health. Female gender, HIV risk group, number of prescriptions, and overall number of drugs used were associated with CAM use. CAM use in Canadian patients with HIV is extremely common, with higher use among women. The definition of CAM has a substantial impact both on reported prevalence rates and on predictors of CAM use.

Abstract
CONTEXT Homeopathic medicine developed significant popularity in the nineteenth century in the United States and Europe as a result of its successes treating the infectious disease epidemics during that era. Homeopathic medicine is a medical system that is specifically oriented to using nanopharmacologic and ultramolecular doses of medicines to strengthen a person's immune and defense system rather than directly attacking the microbial agents. OBJECTIVES To review the literature referenced in MEDLINE and in nonindexed homeopathic journals for placebo-controlled clinical trials using homeopathic medicines to treat people with AIDS or who are human immunodeficiency virus (HIV)-positive and to consider a different theoretical and methodological approach to treating people with the viral infection. FINDINGS A total of five controlled clinical trials were identified. A double-blinded, placebo-controlled study was conducted on 50 asymptomatic HIV-positive subjects (stage II) and 50 subjects with persistent generalized lymphadenopathy (stage III) in whom individualized single-remedy homeopathic treatment was provided. A separate body of preliminary research was conducted using homeopathic doses of growth factors. Two randomized double-blinded, placebo-controlled studies were conducted with a total of 77 people with AIDS who used only natural therapies over a 8-16-week period. Two other studies were conducted over a 2.5-year period with 27 subjects in an open-label format. SETTINGS The first study was conducted by the Regional Research Institute for Homeopathy in Mumbai, India, under the Central Council for Research in Homeopathy, with the approval of the Ministry of Health and Family Welfare, Government of India. The second body of studies was conducted in clinic settings in California, Oregon, Arizona, Hawaii, New York, and Washington. RESULTS The first study found no statistically significant improvement in CD4 T-lymphocytes, but did find statistically significant pretest and post-test results in subjects with stage III AIDS, in CD4 (p = 0.008) and in CD8 (p = 0.04) counts. The second group of studies found specific physical, immunologic, neurologic, metabolic, and quality-of-life benefits, including improvements in lymphocyte counts and functions and reductions in HIV viral loads. CONCLUSIONS As a result of the growing number of people with drug-resistant HIV infection taking structured treatment interruptions, homeopathic medicine may play a useful role as an adjunctive and/or alternative therapy.

Abstract
BACKGROUND Leishmania coinfection is frequently seen in human immunodeficiency virus (HIV)-infected patients in endemic areas, and from time to time the protozoan is detected in cutaneous biopsies. OBJECTIVE To establish the characteristics and possible ethiologic role of the presence of Leishmania in these lesions. METHODS We studied 12 cutaneous biopsies with Leishmania organisms from nine HIV-infected patients (seven men and two women) with visceral leishmaniasis, diagnosed by bone marrow examination, seen over a period of 9 years. RESULTS Based on clinical characteristics, evolution and response to anti-leishmanial treatment, cutaneous alterations were found to be related to the presence of the protozoan in six cases, whereas in the other six cases it was not considered responsible for the dermatological lesions (dermatofibroma, and lesions of psoriasis, Reiter's syndrome, bacillary angiomatosis, cryptococcosis and oral aphthae). Of note was the high prevalence of specific mucocutaneous manifestations, usually accompanied by intense pruritus, great variability, and a tendency to relapse after treatment stopped. On two occasions, detection of the protozoa in skin biopsies led to the diagnosis of a previously unsuspected visceral leishmaniasis. CONCLUSIONS Cutaneous detection of Leishmania is frequent in HIV-infected individuals with visceral leishmaniasis. Sometimes Leishmania is associated with changes attributable to other dermatological processes, and its presence does not imply a causative role. A clear relationship between the systemic process and the therapeutic response is necessary to demonstrate an ethiologic role.

Abstract
HIV and parasitic infections interact and affect each other mutually. Whereas HIV infection may alter the natural history of parasitic diseases, impede rapid diagnosis or reduce the efficacy of antiparasitic treatment, parasitoses may facilitate the infection with HIV as well as the progression from asymptomatic infection to AIDS. We review data on known interactions for malaria, leishmaniasis, Human African Trypanosomiasis, Chagas' disease, onchocerciasis, lymphatic filariasis, schistosomiasis and intestinal helminthiases. The common immunopathogenetic basis for the deleterious effects parasitic diseases may have on the natural history of HIV infection seems to be a particular type of chronic immune activation and a preferential activation of the T helper (Th)2 type of help. Control of parasitic diseases should complement the tools currently used in combating the HIV pandemic.

Abstract
The use of complementary and alternative medicine (CAM) therapies is widespread in many chronic illnesses, including human immunodeficiency virus (HIV) infection. The objective of this study was to determine the impact of increasingly effective antiretroviral therapy on the use of CAM in an HIV-positive patient population. A written survey was given to 191 HIV-positive outpatients. Participation was voluntary and anonymous. One hundred twenty-eight patients (67%) used CAM at some time to control HIV and 76 (40%) of the patients were currently using CAM. The major forms of CAM used were exercise (43%), lifestyle changes (38%), dietary supplements (37%), counseling (27%), herbal medications (26%), megavitamins (24%), and prayer therapy (24%). One hundred forty-one patients (74%) used a protease inhibitor medication, 28 (15%) used a protease inhibitor sparing regime, and 22 (11%) had no current or prior antiretroviral use. Eighty-two (43%) patients indicated that their doctor knew they used CAM and 56 patients (29%) received their information about CAM from a doctor or other health care professional. Of 128 patients who used CAM, 90 (70%) felt CAM improved their quality of life. Income of $15,000 or more per year and discontinuation of medications by patients for any reason in the past were the best predicators of CAM use for patients in general and also those on protease inhibitor therapy. CD(4) count, educational status, year of HIV diagnosis, and martial status were not effective predictors of CAM use. Use of CAM remains widespread among patients with HIV infection even with the availability of effective, yet noncurative antiretroviral therapy and does not correlate with type of antiretroviral therapy used or clinical status.

Abstract
A 40-year-old human immunodeficiency virus (HIV)-positive man had three relapses of visceral leishmaniasis (VL). In the third he developed nodular skin lesions of three types, some reminiscent of Kaposi's sarcoma. Biopsy of each type disclosed abundant dermal macrophages with a huge number of intracellular and extracellular Leishman-Donovan bodies. Rapid improvement of lesions was achieved after antiparasitic treatment. AIDS leads to atypical forms of leishmaniasis. Leishmania has been detected both in normal and pathological skin of these patients due to dissemination during VL. It is suspected that a considerable proportion of the population may be infected in endemic areas, Leishmania being opportunistic in immunosuppressed individuals. It is important to recognize the range of lesions that may occur in patients with HIV and VL, many of which are non-specific and may cause diagnostic difficulty.

Abstract
One of the most characteristic clinical features in cutaneous leishmaniasis is the development of nodules followed by ulcerations at the site of infection. Leishmania amazonensis-infected mice show similar ulcerative lesions. Leishmania-infected severe combined immunodeficiency (SCID) mice, however, have been shown to develop nonulcerative nodules. In the present study, the roles of T cells in ulceration were examined using SCID mice in cell reconstitution experiments. After development of nonulcerative nodules, SCID mice were inoculated with splenocytes from either Leishmania-infected or naive immunocompetent mice, resulting in ulceration in all mice. When naive splenocytes were depleted of CD4(+), CD8(+), or B220(+) cell populations and the remaining cells were injected into Leishmania-infected SCID mice after the development of nodules, only SCID mice inoculated with splenocytes depleted of CD4(+) cells did not show ulceration. The evidence obtained in this study clearly shows that the CD4(+) cell population is indispensable for ulceration in leishmaniasis lesions of SCID mice.

Abstract
CONTEXT Alternative medicine or complementary remedies that have not been scientifically tested are nonetheless widely used to treat chronic illnesses, particularly if curative options are limited. OBJECTIVES To assess the effectiveness of Chinese medicinal herbs in reducing symptoms and improving the quality of life of HIV-infected persons. DESIGN Prospective, placebo-controlled double-blind study. SETTING University-based HIV outpatient clinic. PATIENTS 68 HIV-infected adults with CD4 cell counts <0.5 x 10(9)/L. INTERVENTION Participants were randomized to receive four daily doses of seven pills containing a standardized preparation of 35 Chinese herbs or placebo for 6 months. MAIN OUTCOME MEASURES Symptoms, HIV disease progression, HIV-1 RNA plasma viral loads, CD4 and CD8 cell counts, and scores on standard questionnaires for quality of life, depression, anxiety, and coping. RESULTS Intervention and placebo groups were equivalent at baseline regarding, respectively, previous antiretroviral therapy (74% versus 79%), median CD4 cell counts (0.20 x 10(9)/L versus 0.25 x 10(9)/L), and median HIV-1 plasma viral loads (35,612 copies/ml versus 52,027 copies/ml). At enrollment, none of the study subjects was seriously ill or depressed, and average coping and quality of life scores were in the normal range. In all, 53 (78%) participants completed the study. Patients taking Chinese herbs reported significantly more gastrointestinal disturbances (79% versus 38%; p = .003) than those receiving placebo. No therapy-related toxicities were observed. At completion of the study, no significant differences between the intervention and placebo groups were found regarding plasma viral loads, CD4 cell counts, symptoms, and psychometric parameters. HIV-1 RNA level was unchanged at study end. Among participants who were not on concomitant antiretroviral therapy, median CD4 cell counts declined by 0.05 x 10(9)/L in both the intervention and placebo groups. CONCLUSIONS This standardized formulation of Chinese herbs for HIV-infected individuals did not improve quality of life, clinical manifestations, plasma virus loads, or CD4 cell counts. The data suggest that this formulation of Chinese herbs is not effective when administered in a Western medicine setting.

Abstract
Leishmania amazonensis is an intracellular protozoan parasite of macrophages. Cutaneous leishmaniasis in an immunocompetent host begins as papules or nodules followed by ulceration at the site of promastigote inoculation. In this study, the pathological changes of cutaneous leishmaniasis lesions in T cell deficient nude mice were examined. When infected with L. amazonensis promastigotes, nude mice developed non-ulcerative cutaneous nodules. By histological examination of cutaneous lesions, massive accumulation of vacuolated histiocytes containing amastigotes was observed in all the nude mice. Although infiltration of mononuclear and polymorphonuclear cells was seen in the lesions of immunocompetent mice, few such cells were observed in the lesions of nude mice. These results indicate the importance of T cells on the ulcer formation in cutaneous leishmaniasis.

Abstract
Cutaneous leishmaniasis begins as papules or nodules at the site of promastigote inoculation. The next key pathogenic event in this disease is the formation of an ulcer at this site. Leishmania infection in immunodeficient mice, however, showed non-ulcerative cutaneous lesions suggesting the involvement of the immune system in ulcer formation. Severe combined immunodeficient (SCID), recombination-activating gene 2 knockout (RAG-2-/-), and immunocompetent mice were inoculated subcutaneously with cultured L. amazonensis promastigotes. Macroscopic nodules appeared at the inoculation site within 2 weeks of infection in all the mice and gradually extended to the surrounding skin tissue. Although nodules of immunocompetent mice ulcerated within 6 weeks, immunodeficient mice did not form ulcers even after 25 weeks of inoculation. These results strongly suggest the importance of functional T and B cells in ulcer formation of cutaneous leishmaniasis and are consistent with clinical features of non-ulcerative cutaneous leishmaniasis in some AIDS patients. The present study also indicates that the L. amazonensis-infected immunodeficient mouse model might be suitable for studying the mechanisms of ulcer formation in cutaneous leishmaniasis.

Abstract
Leishmaniasis is a chronic parasitic protozoal disease transmitted by sandfly vectors and is endemic in some regions of South America, Asia, Africa and Mediterranean countries. This case report describes a British patient who presented with oral mucosal leishmaniasis and in whom it was also the first sign of HIV disease. We believe it is the first reported case of isolated oral mucosal leishmaniasis as a presenting feature of otherwise unknown HIV infection.

Abstract
Visceral leishmaniasis (VL) is a well recognized opportunistic infection in patients with HIV-1 infection, which may occasionally present with atypical features. We describe two patients with advanced HIV-1 infection (CD4<100/ mm3) in whom visceral leishmaniasis presented with atypical features, and their response to therapy. Atypical features of visceral leishmaniasis in the two infected patients include absence of fever, dissemination to the duodenal mucosa and to the skin as xanthoma-like lesions. Therapy and secondary prophylaxis remain unsatisfactory, and studies to evaluate combinations of amphotericin B and immunotherapy are needed.

Abstract
OBJECTIVE To identify sociodemographic and clinical characteristics of persons using complementary therapy in an HIV/AIDS drug treatment program and to evaluate the associations between complementary therapy use and participant characteristics. METHODS A cross-sectional study using program participants who completed an annual participant survey between 09/95 and 06/96. Surveys gathered data on use and motivations for use of complementary therapies. Complementary therapies included dietary, medicinal, tactile, and relaxation therapies. Statistical analyses were carried out using parametric and nonparametric measures and multivariate logistic analyses. Multivariate modeling considered age, income, education, time spent out of bed, and degree of pain as independent variables against complementary therapy use (Yes versus No). All reported p values are two-sided. RESULTS A total of 657 participants completed an annual participant survey within the study period. Of these, 256 participants (39%) had ever used complementary therapies. Univariate analysis indicated that 195 patients (30%) had used dietary supplements, 141 (22%) had used herbal and other medicinal therapies, 145 (22%) had used tactile therapies, and 128 (20%) had used mental relaxation techniques. Multivariate analysis indicated that complementary use was independently associated with younger median age (p = .003), income >$7,300 U.S. (p = .014), having greater physical pain (p = .003), and a university education (p = .002). CONCLUSION Use of complementary therapies in conjunction with HIV/AIDS medications appears to be most prevalent in young and highly educated individuals and to be associated with the debilitating and chronic nature of HIV disease.
