Forty-nine patients with severe aplastic anemia, 33 due to unknown cause, 11 drug or chemical related, 2 associated with hepatitis, 1 with paroxysmal nocturnal hemoglobinuria, and 2 possibly associated with Fanconi syndrome did not show recovery after 0.5-96 (median 2) mo of conventional therapy. Twenty-two were infected and 21 were refractory to random platelet transfusions at the time of admission. All were given marrow grafts from HLA-identical siblings. Forty-five were conditioned for grafting by cyclophosphamide (CY), 50 mg/kg on each of 4 successive days, and four by 1000 rad total body irradiation. All were given intermittent methotrexate therapy within the first 100 days of grafting to modify graft-versus-host disease (GVHD). Three patients died from infection too early to evaluate (days 1-8). Forty-six had marrow engraftment. Of these, 20 are surviving with good peripheral blood counts between 186 and 999 days, and 18 have returned to normal activities. Chronic GCHD is a problem in five. Twelve patients died of infection following rejection of the marrow graft. Twelve patients died with bacterial or fungal infections or interstitial pneumonia and active GVHD or soon following resolution of GVHD. Two patients died with marrow engraftment and no GVHD, one with an interstitial, and the other with a bacterial pneumonia. Thirty-six patients who had received random donor blood transfusions were randomly assigned to receive either CY or procarbazine-antithymocyte globulin-CY as conditioning regimens to test whether the incidence of graft rejection could be decreased. There was no difference in the incidence of graft rejection between the two regimens. In 13 patients with rejection, second transplants were attempted either with the original marrow donor (9 patients) or another HLA-identical sibling (4 patients). Three of these transplants were not evaluable, seven were unsuccessful and three were successful with only one of the three surviving for more than 468 days. In conclusion, the long-term survival of 41% of the patients in the present study is similar to that achieved in our first 24 patients, and confirms the importance of marrow transplantation for the treatment of severe aplastic anemia. Marrow graft rejection, GVHD, and infections continue to be the major causes of failure.

Severe intercurrent nonthyroidal illnesses (diabetic ketoacidosis, myocardial infarction, fulminant hepatitis and bacterial pneumonia) in four thyrotoxic patients were associated with depression of total serum thyroxine (T(4)) and triiodothyronine (T(3)) values into the normal or even subnormal range. A diagnosis of hyperthyroidism was established by a combination of elevated radioactive iodine uptake, absent thyroid-stimulating hormone response to thyrotropin-releasing hormone or an elevated free T(4) by dialysis values. In the two of four cases that had a fatal outcome, there was a progressive decline in total T(4) and total T(3) values. In contrast, the two surviving patients had a progressive increase of total T(3) and total T(4) values into the hyperthyroid range as their underlying illness resolved. As has been seen with severe nonthyroidal illnesses, pronounced depression of total T(3) and total T(4) levels in hyperthyroid patients may also portend a poor prognosis.

Thirty-six patients with advanced Hodgkin's disease who were treated primarily with MOPP were evaluated to determine the reasons for MOPP failure. Complete remission was achieved in 22 (61%) of the patients, and the predicted 5-year survival rate for all patients is 60%. Reasons for the failure of MOPP to cure patients in this series included: 1) Idiosyncratic drug reactions in 2 patients (6%). MOPP was discontinued after one cycle because of drug-related hepatitis or skin rash; 2) Resistant disease in 8 patients (22%). Primary treatment failure was significantly associated with the presence of B symptoms (p = .005) and age greater than 40 years (p = .02); 3) Death from complicating infection in 5 patients (14%). Four patients died without evidence of Hodgkin's disease while responding to MOPP from pneumocystis pneumonia, viral pneumonia, bacterial pneumonia, or bacterial septicemia. One patient died in complete remission from sudden, overwhelming sepsis; 4) Relapse from complete remission in 4 patients (11%). All patients who relapsed had deviations from the planned dose or timing of MOPP. Remission duration was shorter (p = .06) in patients with documented deviations in MOPP administration than in patients without such changes. It appears that new treatment approaches are needed for patients with B symptoms, and that failure to deliver MOPP on schedule in the planned dose increases the risk of relapse.

The autopsy records of 115 children with severe protein-energy malnutrition were reviewed. Sections of the lung histology showed evidence of bacterial pneumonia in 49% of cases. An additional 18% showed bronchitis, bronchiolitis or interstitial pneumonitis. Aspiration of gastric contents was evident in 10% of cases; 6% showed pulmonary oedema and congestion. In the remaining cases, no lung pathology was identified (17%). In 8 cases, rapid autopsy examination permitted fixation of lung tissue for electron microscopy. These included 4 cases of bronchopneumonia, one of which was associated with viral pneumonia. Another interstitial pneumonitis, probably of viral aetiology, was also studied. Both these virus-associated cases showed loss of type I pneumocytes and hyperplasia of type II pneumocytes. Another patient with herpes simplex hepatitis showed necrotic emboli in pulmonary capillaries with virions, as well as colonies of interstitial bacteria. One patient with acute pulmonary oedema displayed severe endothelial cell swelling on electron microscopy. In one case, there was no evidence of respiratory changes, apart from desquamation of type I pneumocytes. Useful information can be obtained on the fine structure of the lung, using samples taken soon after death.

The clinical and laboratory characteristics of 201 cases of measles and its associations with complications were analyzed during an outbreak of this disease in Mexico City. The complications were hepatitis (45%), bacterial pneumonia (17%), oral candidiasis (13%), upper gastrointestinal tract hemorrhage (13%), epistaxis (8%), encephalitis (4%), subcutaneous emphysema (2%), and hypocalcemic tetany (1%). In a subgroup of 20 consecutive patients hypocalcemia was found in 14 cases (70%), associated with high levels of calcitonin in three cases. An increased lactate dehydrogenase (LDH) was observed in 83% of the patients, showing a significant association with the occurrence of complications (p = 0.04) especially in the patients with values of LDH above 750 IU/mL (odds ratio of 6.4). Two patients died (1% mortality). The young patients with measles can develop serious complications, and an increased level of LDH may be a prognostic indicative of these complications.

Over a period of 2 months an 88-year-old man developed progressively more severe breathing-related pain under the right shoulder blade, loss of appetite, general weakness, depressive mood, sub-febrile temperature and nocturnal sweating. Various inflammation parameters were raised (sedimentation rate 43 mm in the first hour; C-reactive protein 26 mg/dl; white cell count 12,500/microliters). There also were pleural effusion and signs of mild nonspecific hepatitis. Antibiotics were administered because bacterial pneumonia was suspected. But the patient's condition deteriorated and he developed nightly periods of disorientation. There was no evidence for any advanced malignancy. Immunological tests pointed towards older-onset systemic lupus erythematosus: titre for antinuclear antibodies markedly raised to 1:20 480; anti-DNA titre moderately raised to 1:125 IU/ml. The patient's general condition and the pleuritic pain improved within 2 days under treatment with prednisone (50 mg daily); the depression, disorientation and fever receded within a week. The anti-DNA titre fell to 47 IU/ml after 8 weeks. He was able to resume his usual social activities and was kept on a maintenance prednisone dose of 5.0 mg daily.

Effective antiretroviral therapy initially resulted in large decreases in hospitalization rates of HIV-infected patients. The goal of this study was to determine whether these gains were being maintained in 2001. A cross-sectional study of hospital admission characteristics during four time periods was performed. All patients receiving care at the HIV clinics of New York Presbyterian Hospital-Cornell Medical Center (NYPH) in New York City were included. In 1995, 883 outpatients were receiving care for HIV infection at NYPH; this increased to 1990 outpatients by 2001. Demographic and laboratory information was obtained for these outpatients, and diagnoses were recorded for all patients requiring hospitalization on at NYPH during the time periods January 1 through June 30, in 1995, 1997, 1999, and 2001. The incidence of hospital admission declined in all four time periods: 1995 (95 per 100 patient-years [pt-yr]), 1997 (48 per 100 pt-yr), 1999 (38 per 100 pt-yr, p < 0.05), and 2001 (25 per 100 pt-yr). The incidence of bacterial pneumonia and opportunistic infections (OIs) decreased in all four time periods. The median hospitalization were CD4(+) cell count for outpatients increased from 231 (1995) to 364 (2001). Important predictors of hospitalization were CD4(+) < 200, and IVDU as an HIV risk factor. Since 1995 and the introduction of highly active antiretroviral therapy, continuing increases in CD4(+) cell counts of outpatients has been reflected in persistent declines in hospitalization rates. Large decreases in OIs and pneumonia have been minimally offset by stable rates of hospital admissions for diagnoses such as hepatitis, cirrhosis, and cellulitis.

The effects of measles are relatively mild in well-nourished children, but are associated with high mortality in those who are malnourished and in those who have other diseases. Complications may include bacterial pneumonia, bronchitis, otitis media, gastroenteritis, myocarditis, hepatitis, and encephalomyelitis. The Expanded Program on Immunization was introduced to India in 1978, but measles immunization did not commence until 1985 under the Universal Immunization Program. Total district coverage was achieved in 1990, followed by a peak immunization coverage figure of 90.9% in 1991. Coverage rates declined, however, to 85.8% in 1992-93. Impressive though they may be, these coverage rates obfuscate the reality that measles remains a major cause of morbidity and childhood mortality in India. Coverage levels remain under 50% in many tribal and remote areas, with 49,453 notified cases at the time of printing. Overall case fatality rates for the country are in the range of 2-15% due to a synergistic relationship between malnutrition and infection. One must therefore not rest in the fight against measles. Sudden outbreaks should be reported immediately and vitamin A supplements and immunization supplies readied in anticipation of epidemic. The many reasons why vaccine coverage rates remain low in some areas include the failure of many parents, health personnel, and some doctors to regard measles as a serious disease; restrictive vaccine administration directives requiring the presence of a physician; physician reticence to open a 10-dose vial for 1-2 patients; and parental and physician reluctance to immunize children who are slightly ill or where minor adverse side reactions such as fever and rash may be anticipated.

We retrospectively reviewed 34 consecutive patients with serologically confirmed leptospirosis admitted during years 1992-2002. Nine patients (26.5%) had respiratory symptoms on admission including cough (n = 4), shortness of breath (n = 4), cyanosis (n = 2), and hemoptysis (n = 1). Six patients had pulmonary radiographic findings including (1) diffuse, ill-defined, ground-glass density (n = 3); (2) diffuse alveolar opacities (n = 2); and (3) small nodular density (n = 1). Male/female ratio was 8/1 and mean age was 47 years. Seven patients reported their exposure source including hunting (n = 2), fishing (n = 2), fresh water swimming (n = 2), and canoeing (n = 1). All patients had fever (mean = 40.1 degrees C). Other common symptoms were headache (n = 4), vomiting (n = 3), and myalgia (n = 3). Biological abnormalities included elevated liver enzymes (n = 8), proteinuria (n = 7), lymphopenia (n = 6), hematuria (n = 5), renal failure (n = 4), anemia (n = 4), and elevated neutrophil count (n = 4). PaO(2 )was measured for 3 patients while they were breathing room air (32, 55, and 66 mmHg). Suspected diagnosis on admission included leptospirosis (n = 2), bacterial pneumonia (n = 2), intoxication, influenza, viral hepatitis, biliary tract lithiasis, and rapidly progressive glomerulonephritis (one patient each). The first serologic testing for leptospirosis was positive for 5 patients (55%). Serovar was presumptively identified for 7 patients: Australis (n = 3), Grippotyphosa (n = 2), and Icterohaemorrhagiae (n = 2). Seven patients were treated with penicillin; two patients received no antibiotics. All patients were cured. In conclusion, patients with leptospirosis may present predominantly with nonspecific pulmonary symptoms. In these patients, leptospirosis must be suspected when there is a potential exposure to rats, especially in case of high-grade fever, myalgia, hepatitis, and renal abnormalities.

We describe a 26-year-old female referred to us because of recurrent bacterial pneumonia. Her immunoglobulin profile on admission was; IgG 1920 mg/l, IgA 60 mg/l, IgM 260 mg/l, IgD below 20 mg/l, IgE below 1 kU/l. Antinuclear antibodies, EBV VCA IgM, anti-parvovirus B19 IgM antibodies and hepatitis infection markers were all negative. Bone marrow aspiration revealed normal cellularity without abnormal cells, especially plasma cell proliferation. No rearrangement for IgH and TCR was observed as determined by Southern blot analysis. By the given data, a diagnosis of common variable immunodeficiency (CVID) was made. The genesis of this disease remained unclear. In this study, proliferation and immunoglobulin production with or without several stimulators were examined. Proliferation stimulated by PHA, Con-A, LPS, or IL-2 was decreased compared to that of healthy individuals. Immunoglobulin production after stimulation with several agents was quite low. Interestingly, however, IL-2 or IL-4 could increase IgM production on 6 days culture significantly. These results indicate that IL-2 or IL-4 possibly restore T cell responses to several antigens and induce B cell differentiation.
