The microbiology, epidemiology, clinical features, diagnosis, and treatment of histoplasmosis are discussed. Histoplasmosis usually presents as a disseminated infection with fever and weight loss. Respiratory complaints, local or generalized lymphadenopathy, hepatosplenomegaly, colonic lesions, and skin and oral ulcers may also be present. Diagnosis is usually made by culturing the fungus from blood or other clinical specimens, or by histopathologic examination of bone marrow aspirate or biopsy material. Treatment is usually lifelong since the risk of a relapse is substantial if therapy is stopped. A data table is provided for managing AIDS-associated histoplasmosis and the response rate percentage for each therapy used is given.

This is a case report of a 29 year old male with pneumocystis pneumonia and tuberculosis, and who was initially suspected of having HIV infection, based on risk factor analyses, but was subsequently shown to be HIV negative. The patient arrived at the hospital with fever, cough, weight loss, loss of appetite, pallor, and arthralgia. In addition, he was jaundiced and had cervical lymphadenopathy and mild heptosplenomegaly. He had interstitial infiltrates of the lung, sputum smears positive for Mycobacterium tuberculosis and Pneumocystis carinii, and stool tests were positive for Strongyloides stercoralis and Schistosoma mansoni. He was diagnosed as having AIDS, and was treated for tuberculosis, pneumocystosis, and strongyloidiasis with a good response. The patient did not receive anti-retroviral therapy, pending outcome of the HIV tests. A month later, he was re-examined and found to have worsening hepatosplenomegaly, pancytopenia, fever, and continued weight loss. At this time, it was determined that his HIV ELISA antibody tests were negative. A bone marrow aspirate was done and revealed amastigotes of leishmania, and a bone marrow culture was positive for Leishmania species. He was treated with pentavalent antimony, 20 mg daily for 20 days, with complete remission of symptoms and weight gain. This case demonstrates that immunosuppression from leishmaniasis and tuberculosis may lead to pneumocystosis, and be misdiagnosed as HIV infection. The occurrence of opportunistic infections in severely ill patients without HIV must always be considered and alternate causes of immunosuppression sought.

An 8-years-old boy was admitted with fever of unknown origin, cervical lymphadenopathy and hepatosplenomegaly and weight loss. His mother's HIV infection was diagnosed two weeks before his hospitalization, so he was diagnosed as perinatally acquired AIDS. Serology and serial cultures were negative for viral infections, toxoplasmosis, chagas, tuberculosis and atypical mycobacterium. The patient met clinical and laboratory criteria for hemophagocytic syndrome (HS) that was confirmed on bone marrow aspirate and biopsy. A cervical lymph node biopsy was performed which was diagnosed as Hodgkin's disease (HD) diffuse fibrosis lymphocyte depletion subtype. EBERs in situ hybridization and LMP-1 immunohistochemistry on the lymph node biopsy established the EBV association. On the basis of a sequence of appearance of the clinical, laboratory and histological signs, HIV, EBV or HD may have triggered HS as the last fatal event in this pediatric patient.

Multicentric Castleman disease (MCD) is a heterogeneous lymphoproliferative disorder, characterized by systemic symptoms, generalized lymphadenopathy, hepatosplenomegaly, proteinuria, and rash. The clinical course is variable and may range from indolent to aggressive, fulminating in a rapidly fatal illness. Mortality is usually from infective complications and less commonly from malignancies, such as lymphoma or Kaposi sarcoma. The association of concurrent or preceding Castleman disease with Kaposi sarcoma is well documented. Castleman disease developed in a 51-year-old patient with AIDS about 10 months after diagnosis of Kaposi sarcoma. MCD was found to be associated with human herpesvirus 8/Kaposi sarcoma-associated herpesvirus.

A 29 year old Thai woman presented with non-specific features and examination revealed left upper zone consolidation and hepatosplenomegaly. The initial clinical differential diagnosis included tuberculosis and melioidosis. She died four days after admission, while still under investigation. Postmortem examination revealed antibodies to human immunodeficiency virus, disseminated Penicillium marneffei infection, and Salmonella enteritidis infection. Penicillium marneffei is a well described AIDS defining pathogen in South East Asia but is very rare in the UK. Appropriate antifungal treatment may be associated with a successful outcome. Increased awareness of this clinical association may enable correct diagnosis in affected patients from South East Asia presenting within the UK.

Two children with non-Hodgkin's lymphoma (NHL) as the presenting illness of acquired immunodeficiency syndrome (AIDS) are described. There was a delay in diagnosing the underlying AIDS in both cases. In the first case, an 18-month-old boy with stage IV, high-grade,T-cell NHL, the diagnosis of underlying AIDS was suspected only when he developed recurrent and profound opportunistic infection during chemotherapy. The second case, an eight-month-old female infant presented initially with hepatosplenomegaly and thrombocytopenia of undetermined cause. She had progressive abdominal distension and swelling of her right eye one year later due to high grade B-cell NHL. She was later found to be sero-positive for HIV during pre-chemotherapy screening. As the prevalence of HIV infection continues to increase, HIV infection should be considered in the differential diagnoses of childhood hepatosplenomegaly and thrombocytopenia, and as a possible underlying cause of childhood cancer, especially NHL.

Although cases of leishmaniasis co-infection have been described in acquired immunodeficiency syndrome patients as well as those who have undergone organ transplants, to our knowledge, the present report is the first documented case of simultaneous cutaneous, visceral and ocular leishmaniasis due to Leishmania (Viannia) braziliensis in a transplant patient. The patient had been using immunosuppressive drugs since receiving a transplanted kidney. The first clinical signs of leishmaniasis included fever, thoracic pain, hepatosplenomegaly, leucopenia and anemia. The cutaneous disease was revealed by the presence of amastigotes in the skin biopsy. After three months, the patient presented fever with conjunctive hyperemia, intense ocular pain and low visual acuity. Parasites isolated from iliac crest, aqueous humor and vitreous body were examined using a range of molecular techniques. The same strain of L. (V.) braziliensis was responsible for the different clinical manifestations. The immunosuppressive drugs probably contributed to the dissemination of Leishmania.

Visceral leishmaniasis (VL), which is transmitted by sandflies, is always present in at least 62 countries and is spreading to areas where it had not existed in the past. VL/HIV co-infections are becoming more and more common. In southern Europe, 25-70% of adult VL cases also have HIV infection. 1.5-9% of AIDS cases have newly acquired or reactivated VL. In the Mediterranean area, VL is the most common opportunistic parasitic infection among AIDS cases (i.e., 100 CD4/mcl). AIDS patients with VL have a much shorter survival period than other AIDS patients. VL can lie dormant for years but emerge clinically if an infected person has immunosuppression. Most VL/HIV co-infections in the western hemisphere are in Brazil. East African countries reporting VL/HIV co-infections include Ethiopia, Kenya, Malawi, and Sudan. Only one VL/HIV co-infected case has been found in Cameroon and in Guinea Bissau. VL/HIV co-infection cases tend to not have the usual VL clinical signs and symptoms (fever, weight loss, hepatosplenomegaly, polyadenopathies), making clinical diagnosis difficult. Since VL test sensitivity in HIV positive patients is reduced 20-40%, it is also difficult to make a serological diagnosis. In the first VL episode of HIV-infected patients, clinicians should use BMA, the safest and most sensitive test. Drug options for VL treatment include pentavalent antimonials, pentamidine, amphotericin B, and amphotericin B encapsulated in liposomes. Treatment failure is rather common in VL/HIV co-infected patients. Researchers from different centers need to conduct trials of various multi-therapy schedules. 70% of VL/HIV co-infected cases in southern Europe use intravenous drugs, suggesting that sharing of needles may account for the co-infection. The World Health Organization has mobilized against VL/HIV co-infections, including setting up a minimal surveillance system.

This paper presents a case study on the neonatal acquisition of the Acquired Immunodeficiency Syndrome (AIDS) transmitted transplacentally from mother to baby. 3 years before the delivery the mother had received a (contaminated) blood transfusion because of an abortion. The mother of the baby infected her husband. 2 other children in the family, ages 6 and 7, were seronegative confirming that HIV can only be transmitted through sexual contact, blood transfusions and perinatally. HIV can be transmitted perinatally in 3 ways: 1) transplacentally; 2) during delivery and postpartum through breastfeeding. The baby in this study acquired HIV in the uterus and developed symptoms such as those found in AIDS. His clinical symptoms included low birthweight, poor growth, diarrhea, hemorrhages, hyperthermia, hepatosplenomegaly and recurrent infections. There is concern that HIV transmitted perinatally is on the increase in Mexico due to the growing numbers of bisexuals. 68.9% of women in reproductive ages have already been diagnosed with AIDS and have acquired it through bisexual contacts.

Cryptococcal meningitis (CM) is the commonest life threatening opportunistic fungal disease in Human Immunodeficiency Virus (HIV) infected individuals. But there are very little reports of lymphadenopathy along with cryptococcal meningitis, although cases of pulmonary, Intestinal, Bone marrow and retinal involvement have been described earlier. Here we report a case of cryptococcal meningitis associated with generalized lymphadenopathy and hepatosplenomegaly.
