Patients with systemic lupus erythematosus (SLE) have increased susceptibility to infection by Pneumocystis carinii, but this condition has rarely been reported in Taiwan. Here, we describe two cases of patients with SLE who developed
Pneumocystis carinii pneumonia
(
PCP
). The first patient was a 39-year-old woman presenting with fever and dyspnea that had lasted 2 weeks. Chest roentgenography disclosed bilateral interstitial and alveolar infiltrates. The second patient was a 22-year-old woman presenting with a 4-day history of malaise, cough, dyspnea, and fever. She had concomitant Mycobacterium tuberculosis infection. Both patients had been treated with varying doses of corticosteroids and/or cytotoxic drugs within 4 months before presentation. Diagnosis was established based on the findings of bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB). Both patients received trimethoprim-sulfamethoxazole (20 mg.kg-1.d-1 trimethoprim), but finally died of nosocomial
septicemia
(Acinetobacter baumanni and Pseudomonas aeruginosa bacteremia in one, P. aeruginosa bacteremia in the other). These two cases demonstrate that
PCP
should be included in the differential diagnosis of patients with SLE presenting with pneumonic processes. In addition, a second opportunistic pathogen should be suspected. Bronchoscopic examination should be performed if the diagnosis is not clear and should include TBLB and BAL.

In general, a rule for corticosteroids in preventing or relieving the acute respiratory distress syndrome (ARDS) has yet to be established, although these drugs are indicated for conditions such as
Pneumocystis carinii pneumonia
. High-dose corticosteroids have not been shown to reduce mortality through their anti-inflammatory properties when given early to patients with
sepsis
, septic shock, or ARDS. Corticosteroids have been shown, however, to reduce mortality in patients with late ARDS only in one small, inconclusive study. More recent investigators have focused on the usefulness of low-dose corticosteroids in reducing mortality in patients with
sepsis
or septic shock who may have relative adrenal insufficiency, but these studies also are inconclusive, and it is unclear that low-dose corticosteroids affect the development of ARDS in these patients.

This article reports on the recommendation of the WHO/Joint UN Program on AIDS/HIV to promote the use of cotrimoxazole for the prevention of HIV-related infections in Africa. Several arguments have been raised since the recommendation for its use. Controversies lie in its efficacy in treating opportunistic infections despite its use for
Pneumocystis carinii pneumonia
. Researchers, however, argue that the drug is effective in preventing certain kinds of bacterial pneumonia and diarrheal diseases, as well as certain
septicemia
. Furthermore, it can also protect the individual against toxoplasmosis and isosporiasis. Another challenge faced in deciding whether to recommend the use of cotrimoxazole is the risk of creating microbial resistance to the drug if it is widely used as a prophylactic. Weighing the use of cotrimoxazole against the two challenges of differing infections and possible resistance in a region like sub-Saharan Africa would still yield to the urgent need of preventing opportunistic infections in people living with AIDS/HIV.

To determine the spectrum of HIV-related illnesses presenting to a rural primary and secondary healthcare facility in Central Thailand, a cross-sectional study was conducted. Routinely collected data were extracted from outpatient medical notes for all adult HIV-infected new attenders of the Manorom Christian Hospital Infectious Disease Clinic. Data concerning inpatient admissions of HIV-infected individuals were collected from ward admission books and discharge summaries. Complete data were available for 229 outpatients, 70% of whom were men. The median age at presentation was 31 years for men and 30 years for women. The majority of the outpatients were married (69%) and infected heterosexually (91%). The commonest conditions requiring admission were cryptococcal meningitis (15%), bacterial pneumonia (12%), extrapulmonary tuberculosis (12%),
Pneumocystis carinii pneumonia
(7%), cerebral toxoplasmosis (4%) and pulmonary tuberculosis (3%). Of the patients presenting for the first time, 32% had AIDS-defining illnesses. Presentations with some conditions, such as tuberculosis and
septicemia
, were fewer than expected. The common opportunistic infections among HIV-infected adults in this rural region are treatable and preventable. Most patients present with advanced disease and earlier diagnosis, through improved access to voluntary counseling and testing, would enable them to receive appropriate preventive therapies and antiretrovirals as they becomes available. The high prevalence of cryptococcal disease suggests that prophylactic anti-fungal therapy may be of value in this area.
Septicemia
and tuberculosis may be under-diagnosed, highlighting the need for improved diagnostic laboratory facilities or treatment based upon validated clinical algorithms. Community care and palliative care services for HIV-infected individuals will increasingly be required in this region.

The X-linked hyper-IgM (XHIGM) syndrome is an uncommon primary immunodeficiency disease caused by mutations in the gene for CD40 ligand and characterized by normal or elevated serum IgM, reduced levels of IgG and IgA, and defective T-cell function. Because of its rarity, it has been difficult for any single investigator or institution to develop a comprehensive clinical picture of this disorder. Accordingly, a national registry was developed in the United States to provide demographic, genetic, immunologic, and clinical information on a relatively large number of patients with the XHIGM syndrome.A total of 79 patients from 60 unrelated families were registered between January 1997 and July 2002. The estimated minimal incidence was approximately 1/1,030,000 live births. All of the patients had significant IgG deficiency and most had IgA deficiency, but only one-half had elevated IgM levels. Most patients presented initially with a history of an increased susceptibility to infection including
Pneumocystis carinii pneumonia
. The average age of diagnosis was significantly earlier in patients born into a family with a previously affected individual. However, only one-third of the patients born into a family with a previously affected individual were diagnosed exclusively because of the presence of the positive family history before any clinical symptoms developed. Over half the patients developed symptoms of immunodeficiency and were diagnosed by 1 year of age, and over 90% by 4 years of age. The most prominent clinical infections were pneumonia (81% of patients), upper respiratory infections (49%) including sinusitis (43%) and recurrent otitis (43%), recurrent/protracted diarrhea (34%), central nervous system infections (14%),
sepsis
(13%), cellulitis (13%), hepatitis (9%), and osteomyelitis (1%). In addition to infections caused by encapsulated bacteria, opportunistic infections were relatively common and were caused by P. carinii, members of the herpes virus family (including cytomegalovirus), Cryptosporidium, Cryptococcus, Candida, Histoplasma, and Bartonella. Sclerosing cholangitis occurred in 5 patients and in 4 of these was associated with Cryptosporidium infection. Eight patients had died at the time of their entry into the Registry; 2 of pneumonia (1 P. carinii and 1 cytomegalovirus), 2 of encephalitis (1 ECHO virus and 1 cytomegalovirus), 2 of malignancy (both hepatocellular carcinoma), 1 of sclerosing cholangitis caused by Cryptosporidium, and 1 of hemolytic uremic syndrome.

Pentostatin is a purine nucleoside analog with demonstrated activity in low-grade lymphoid malignancies. The purpose of this study was to determine the dose of pentostatin (dCF) that could be combined with chlorambucil and prednisone to treat chronic lymphocytic leukemia (CLL), evaluate the toxicity of the resulting regimen and to estimate its efficacy. This was a multi-institutional Eastern Cooperative Oncology Group (ECOG) phase I-II study. Individuals with active B-CLL were eligible if they had no prior treatment or were in sensitive first relapse, provided they had normal renal and hepatic function. Pentostatin was evaluated in combination with orally administered chlorambucil 30 mg/m2 and prednisone 80 mg/day, 1-5 of each 14-day cycle. The pentostatin dose was 2 mg/m2 IV, day 1 for the first 6 patients; 3 mg/m2 IV, day 1 for the next 6 patients; and 4 mg/m2 IV, day 1 for the last set of 6 patients. Fifty-five patients were entered. Because of increasing toxicity with no apparent improvement in clinical efficacy on escalation of the pentostatin dose, 2 mg/m2 was chosen as the phase II dose, and 43 patients were treated at this level. Thirty-nine of these patients were eligible, of which 38 were evaluable for response, 36 of these 38 had no prior treatment. Complete response (CR) manifested by normal bone marrow morphology, peripheral blood counts and resolution of any lymphadenopathy or hepatosplenomegaly occurred in 17 patients (45%). The overall objective response rate was 87%. The median response duration was 33 months and the median survival 5 years. The median time to treatment failure is 32 months. Severe (Grade 3+) infections were seen in 31% of patients and included bacterial pneumonia (n = 4),
Pneumocystis pneumonia
(n = 1), fungal pneumonia (n = 2), urinary tract infection with
sepsis
(n = 1) and Herpes Zoster (n = 5). Overall, 11 patients had H. Zoster while on study. Due to toxicity, 33% of patients stopped therapy. Pentostatin, chlorambucil and prednisone is a highly active regimen in CLL but cannot be recommended in present form because of an unacceptable incidence of opportunistic infections. These findings add to other recent reports which suggest combination therapy with pentostatin and alkylators are active in B-CLL. However, these combination chemotherapies will need to be combined with appropriate addition of anti-bacterial and anti-viral prophylaxis to reduce infection risk for B-CLL patients.

A 45-year-old homosexual man with
pneumocystis pneumonia
and esophageal candidiasis tested positive in ELISA and Western blot analysis for HIV-1. His CD4+ T cell count was 43/microL and his HIV-RNA load was 250,000 copies/mL. He was treated with Trimetoprim-Sulfamethoxazole, Prednisolone and Fluconazole. Valganciclovir was added to treat CMV retinitis. During the clinical course, 21 days after admission, the patient presented with a temperature of 39 degrees C and blood analysis showed neutropenia. Cefepime and G-CSF were initiated, but new consolidation was observed in the upper left lobe in chest radiography. He underwent bronchoscopy and lavage culture was positive for Aspergillus fumigatus. Serum testing of galactomannan was also positive and pulmonary aspergillosis was diagnosed. The patient was initially treated with Micafungin but switched to Voriconazole when clinical symptoms worsened. An eventual clinical response was observed and pulmonary aspergillosis was controlled. Unfortunately, he died of
sepsis
due to MRSA 2 months later. Pulmonary aspergillosis is a devastating complication with poor prognosis in patients with HIV infection. Amphotericin-B has been the mainstay of pulmonary aspergillosis treatment, but reports indicate mortality exceeding 80%. Use of Voriconazole, a relatively new antifungal agent, may lower mortality with fewer adverse effects than conventional antifungal therapy.

The aim of this study was to investigate the causes of death among 129 AIDS patients that were autopsied at the Tropical Medicine Foundation of Amazonas between 1996 and 2003. The degree of concordance between the autopsy diagnoses and the clinical diagnoses was observed. The disease that most frequently caused death was tuberculosis (28%), followed by bacterial pneumonia (17%), histoplasmosis (13%), toxoplasmosis (10%),
pneumocystosis
(8%), cryptococcosis (5%), bacterial
sepsis
(4%) and other causes (15%). The concordance between the clinical diagnosis before death and the autopsy was 51.9%. The main organ involved was the lungs (82.2%). The length of survival from the time of the laboratory diagnosis to death ranged from one month to 120 months. The mean length of survival was 15 days and 56% died less than one month after the diagnosis, while 15 patients died on the same day that they were diagnosed. These results show the importance of autopsies in elucidating the causes of death among AIDS patients.

A 78-year-old woman with rheumatoid arthritis treated with methotrexate and corticosteroid was admitted to our hospital for dry cough and dyspnea. She was diagnosed as having
Pneumocystis pneumonia
based on elevated beta-D-glucan and positive PCR analysis of bronchoalveolar lavage fluid for Pneumocystis jirovecii. We started trimethoprim-sulfamethoxazole and high-dose corticosteroid therapy. Her pulmonary lesions gradually improved; however, she developed perforation of the ileum and subsequently died from
sepsis
. Histology of the perforated site was compatible with cytomegalovirus enterocolitis.

In Brazil, all patients who fulfill the criteria for AIDS have had free access to antiretroviral therapy since 1996. We performed this cross-sectional study to evaluate the causes of death among 643 HIV-infected patients over three non-consecutive years (2000, 2006, and 2010), using their epidemiological, clinical, and laboratory data. The causes of death were classified as AIDS-defining or non-AIDS-defining conditions. We observed a progressive increase in the prevalence of HIV infection over the study period, although there was also a decrease in the mortality rate for various groups, and especially among pediatric patients. An AIDS-defining condition was recorded as the cause of death for approximately 30% of the patients. There was also a high frequency (>70%) of infectious and parasitic diseases, including opportunistic infections, and the most common diagnoses were
septicemia
, pneumonia, tuberculosis, and
pneumocystosis
. Acute respiratory failure was the underlying cause of death in 30% of these cases. Despite advances in HIV therapy, the mortality rate remains high in Brazil. As few Brazilian studies have investigated HIV/AIDS-related mortality, it is important to evaluate and improve the mortality notification databases, in order to provide information regarding the effects of HIV and to guide the implementation of appropriate healthcare measures.
