Sixty patients who fulfilled the WHO case definition of acquired immunodeficiency syndrome (AIDS) were admitted and treated between January 1993 and June 1995 in JIPMER Hospital, Pondicherry, South India. Their mean age was 30.3 +/- 6.4 years. Male: female ratio was 5 : 1. The heterosexual route was the major mode of transmission (96.7%). Fever was the commonest presentation (98.3%), followed by weight loss (85%) and cough (36.7%). The commonest opportunistic infection seen was tuberculosis (pulmonary, extrapulmonary - single or in combination) followed by esophageal candidiasis. Cryptococcal meningitis, intestinal crytosporidiosis, CNS toxoplasmosis, Pneumocystis pneumonia and group B Salmonella septicemia were the other infections encountered. Ten out of the 38 patients with tuberculosis were followed up on antituberculous treatment for 6 months. Seven out of 18 patients with esophageal candidiasis were treated with ketoconazole.

Children with hyper-immunoglobulin M (hyper-IgM) syndrome are at increased risk for Pneumocystis carinii pneumonia (PCP), an opportunistic infection often found in immunodeficient hosts. PCP can present with increasing hypoxia, fever, cough, and respiratory distress. We describe a child with hyper-IgM syndrome in whom bronchoalveolar washings were negative for PCP. However, there was an atypical lung response in which caseating granulomas predominated. The histopathology, resembling that found in tuberculosis, stresses the importance of a high index of clinical suspicion and histologic confirmation for early intervention and treatment. Immunocompromised children with rapidly progressive pulmonary disease may require lung biopsy and stains such as GMS to identify PCP.

Disseminated histoplasmosis has been recognized as a serious opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS). However, cases reported in the literature have been predominantly in adult patients. Here we report an infant with AIDS who presented with fever, cough, rhinorrhea, hepatosplenomegaly, pancytopenia and coagulopathy, and died of respiratory failure. Autopsy revealed disseminated histoplasmosis involving multiple organs including lungs, intestines, liver, spleen, bone marrow, lymph nodes, kidneys, and meninges. The diagnosis was established based on histomorphology and confirmed by blood culture.

Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.

Pneumocystis carinii pneumonia (PCP) is an opportunistic infection that occurs in immunosuppressed populations, primarily patients with advanced human immunodeficiency virus infection. The classic presentation of nonproductive cough, shortness of breath, fever, bilateral interstitial infiltrates and hypoxemia does not always appear. Diagnostic methods of choice include sputum induction and bronchoalveolar lavage. The drug of choice for treatment and prophylaxis is trimethoprim-sulfamethoxazole, but alternatives are often needed because of adverse effects or, less commonly, treatment failure. Adjunctive corticosteroid therapy improves survival in moderate to severe cases. Complications such as pneumothorax and respiratory failure portend poorer survival. Prophylaxis dramatically lowers the risk of disease in susceptible populations. Although PCP has declined in incidence in the developed world as a result of prophylaxis and effective antiretroviral therapy, its diagnosis and treatment remain challenging.

A rare case of pulmonary Nocardia otitidiscaviarum (N. otitidiscaviarum) was encountered in an immunocompetent host. A 74-year-old man was admitted to our hospital with a high fever and a productive cough. His chest radiograph and CT scan revealed infiltrative shadows in the right middle and lower lung fields. Although several antibiotics (third-generation cephalosporin, minocycline, imipenem) were administered, the fever and cough persisted, and C-reactive protein remained elevated. Repeated sputum cultures showed normal flora, so a transbronchial lung biopsy and bronchoalveolar lavage (BAL) were performed bronchoscopically at the right S5. The BAL fluid contained acid-fast, branching filamentous structures. The microorganism was identified as N. otitidiscaviarum by the Research Center for Pathogenic Fungi and Microbial Toxicoses (Chiba University). Trimethoprim-sulfamethoxazole was therefore administered, but the fever continued to rise daily, and C-reactive protein remained elevated. This isolated N. otitidiscaviarum showed resistance to multiple antimicrobial agents in vitro when examined by the disk diffusion method, and so, on the basis of the antibiogram, the patient was treated with clarithromycin (oral, 600 mg/day) plus amikacin (400 mg/day), which proved successful. Testing for pulmonary nocardiosis should be added to the differential diagnosis procedures for refractory pneumonia as an opportunistic infection and for community-acquired pneumonia.

The clinicopathologic spectrum of infections due to nontuberculous mycobacteria (NTM) includes cavitary disease, opportunistic infection, and nodular disease associated with bronchiectasis. We report a less well-described manifestation of NTM infection: 10 immunocompetent patients without preexisting bronchiectasis had radiographic evidence of diffuse infiltrative lung disease. The most common symptoms were dyspnea, cough, hypoxia, and fever. All 10 patients had used a hot tub. Histologic examination revealed exuberant nonnecrotizing, frequently bronchiolocentric, granulomatous inflammation in all cases. In 1 case, necrotizing granulomas were also noted. The inflammation often was associated with patchy chronic interstitial pneumonia and organization. Cultures revealed NTM in all cases (Mycobacterium avium complex in all but 1 case), but staining for acid-fast bacilli was positive in only 1 case. Four patients received corticosteroids alone for presumed hypersensitivity pneumonia, 4 were treated with antimycobacterial therapy, and 2 received both. All patients demonstrated significant improvement at the time of follow-up. These findings suggest that disease due to NTM may manifest as diffuse infiltrates in immunocompetent adults and that hot tub use may be an important risk factor for this disease pattern.

The Centers for Disease Control and Prevention (CDC) has determined that HIV-infected people are more likely to become infected first with Pneumocystis carinii pneumonia (PCP) than any other opportunistic infection. About 53 percent of people who died of AIDS between 1992 and 1997 had PCP. The symptoms of the disease are fever, cough, and breathing problems. PCP is thought to be spread through the air - and not through sexual transmission - so it is difficult to prevent exposure. There is no vaccine against PCP, so the most effective treatment is TMP-SMX, a drug which can prevent PCP. The effects and treatment of PCP in adults and children are described, and contact information is provided.

HIV-infected people in northern Thailand have been devastated by an outbreak of Penicillium marneffei in recent years. The opportunistic infection by the fungus discovered in 1956 has killed thousands of AIDS patients in Thailand. If untreated, it is almost always fatal. Symptoms of infection include fever, chronic coughing, generalized lymphadenopathy, splenomegaly, weight loss, diarrhea, and skin lesions. Treatment with intravenous amphotericin B is successful in 75 percent of patients. After initial treatment for P. marneffei, patients must take prophylactic medicine to prevent a relapse. The fungus probably grows in the soil in Southeast Asia, but only people with severely compromised immune systems become infected.

Over the past 25 years, Eikenella corrodens has increasingly been recognized for its pathogenic potential. Previously identified as an organism most likely to cause opportunistic infection in the immunocompromised host, Eikenella more recently has been implicated in a number of clinical infections in non-immunocompromised patients. We report a case of community-acquired pneumonia, caused by Eikenella, in a patient with diabetes mellitus and a past history of testicular cancer. A review of the literature was conducted in order to review other cases of pulmonary infection with Eikenella, in immunocompetent adults. The condition was diagnosed in 15 patients, occurring most often in men with a mean age of 50. Patients most often presented with fever, cough and pleuritic chest pain. Complications often involved parapneumonic effusion, empyema, and necrotic parenchymal disease. Mortality rates appear to be low. Eikenella is most often susceptible to ampicillin and has variable susceptibility to aminoglycosides. The addition of clindamycin in non-immunocompromised patients with Eikenella infection, co-infected with other pathogens, also appears to be useful. Surgical intervention plays an important role in the recovery of these patients.
