The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

This is a survey of 234 pediatric patients in whom staging laparotomy/splenectomy was carried out (1975 to 1981) in the course of the Intergroup Hodgkin's Disease in Childhood Study (IHDCS). Relapse has occurred in 44 of these patients, and 12 have died, 7 secondary to extension of lymphoma, 2 with herpes or pneumocystis infections, 2 with leukemia, and 1 from an unrelated accident. During the period of surveillance (mean 5.5 yr), five episodes of bacterial sepsis (positive blood cultures) have occurred, including two due to Streptococcus pneumoniae; and three, to Hemophilus influenzae. The former occurred in the small group of patients in this series who had not received the prescribed pneumococcal vaccination. No fatalities were associated with these septic episodes. Intestinal obstruction secondary to adhesions (benign) occurred in eight patients and was managed without intestinal resection or mortality. One patient required operative release of an obstructed ureter following laparotomy, and one, oophorectomy for an infarcted (transposed) ovary.

Central nervous system (CNS) infections in immunocompromised hosts are often accompanied by subtle disorders because immunosuppression usually decreases the inflammatory response. CNS infections in immunocompromised patients are usually caused by organisms different from those found in the general population. The organism causing CNS infection in an immunocompromised host can often be predicted if the type of immune abnormality of the patient is known. The common causes of CNS infection in immunocompromised hosts are reviewed here. Meningitis in patients with neutropenia is usually due to enteric Gram negative bacilli that live in the patient's own digestive tract. Pseudomonas aeruginosa is most common and is followed by E. Coli, Klebsiella, Enterobacter and Proteus. A major risk in patients with abnormal immunoglobulins or splenectomy is infection with encapsulated bacteria, particularly Streptococcus pneumoniae, Haemophilus influenzae and Neisseria meningitidis. Meningitis caused by any of the encapsulated bacteria can be fulminant. Listeria monocytogenes is the most common cause of bacterial meningitis in patients with impaired cellular immunity. Nocardia asteroides is a leading cause of brain abscess in patients with hematologic malignancy. Most patients have evidence of concomitant pulmonary lesions. Fungi are among the most common organisms involving the CNS in immunocompromised hosts. Susceptible patients include those with lymphoma or leukemia and those who receive therapies aimed at suppressing delayed hypersensitivity. Cryptococcus neoformans is a common fungal cause of CNS infection in immunocompromised hosts. The primary site of infection is the lung. Spread to the CNS is via the blood stream. The clinical course is highly variable: meningitis, meningoencephalitis and focal mass lesions. Candida causes meningitis or meningoencephalitis characterized by multiple small abscesses in neutropenic hosts. Organisms reach the CNS via the blood stream usually from the digestive tract or infected intravenous catheters. Aspergillus causes brain abscess, cerebral infarction and focal meningitis in patients with neutropenia. The primary infection is in the lung. The parasites that infest the CNS of immunocompromised patients are usually those that exploit a T-lymphocyte, mononuclear phagocyte host defect. The most common are Toxoplasma gondii and Strongyloides stercoralis. There have been a few cases of amebiasis with dissemination to the brain in patients with hematologic malignancies. Toxoplasma gondii causes major CNS disease in immunocompromised hosts: meningoencephalitis or mass lesions.(ABSTRACT TRUNCATED AT 400 WORDS)

Four cases of fulminant pneumococcal septicemia in splenectomized patients are reported. Three had undergone splenectomy for trauma 42, 28 and 14 years prior to the septicemia. The fourth had been splenectomized for suspected lymphoma 3 years earlier. In 3 out of 4 patients the symptomatology was so rapidly progressive that a physician was consulted within 12 hours. Two patients hospitalized after a second consultation and 20 hours after the first symptoms had evidence of septic shock, disseminated intravascular coagulation and hypoglycemia, and died within a few hours despite early antibiotherapy. Diplococci were seen in peripheral smears of these 2 patients and in the buffy coat of the 3 cases in which this was carried out. These four cases reemphasize the fact that during their entire life splenectomized patients are at risk for development of overwhelming septicemia even when the splenectomy was performed because of trauma. Therefore, such patients should be aware of this risk, should be treated promptly with antibiotics in the event of a febrile episode, and should be vaccinated against pneumococci and possibly other encapsulated bacteria such as Haemophilus influenzae and Neisseria meningitidis.

Pharmacokinetic, bacteriological and clinical studies on SY5555 were performed in children. The results were as follows: 1. A total of 15 patients considered to have bacterial infections were treated with SY5555. Each dose, 5 mg/kg, was orally administered 3 times daily, for 4-11 days. Clinical efficacies of SY5555 in 13 patients with bacterial infections (1 with pneumonia, 2 with bronchitis, each 1 with maxillary sinusitis, 2 with otitis media, 5 with pharyngitis, 1 each with gastroenteritis and pyelonephritis) were evaluated as excellent in 10 patients and as good in 3 patients with an efficacy rate of 100%. Two patients with viral infection and malignant lymphoma were not evaluated. Thirteen causative strains in 7 species were found in 10 patients. Streptococcus pneumoniae in 1/3, Haemophilus influenzae in 2/2, Streptococcus pyogenes 4/4, Salmonella spp. in 1/1, Escherichia coli in 1/1 were eradicated. Only one patient developed mild diarrhea as an adverse reaction. Another patient showed elevated GPT (glutamate pyruvate transaminase). The abnormality was mild and the patient recovered after the cessation of SY5555 administration without specific treatment. 2. MICs of SY5555 were examined against 33 clinical isolates. SY5555 has low MICs against Enterococcus faecalis and other Gram-positive cocci. 3. Pharmacokinetic studies Peak plasma concentrations of SY5555 was 1.15 micrograms/ml at a dose level of 4.9 mg/kg orally administered at fasting. Based on the above results and the broad spectrum of the anti-bacterial activities, SY5555 appears to be a promising antibiotics that is usable as a single agent for the primary therapy of respiratory tract infections, skin soft tissue infections and urinary tract infections in children.

Agammaglobulinaemia is the most common of the primary immunodeficiencies. Three major types can be distinguished: X-linked agammaglobulinaemia, early-onset agammaglobulinaemia and late-onset agammaglobulinaemia. In X-linked agammaglobulinaemia, the molecular defect has been elucidated, and genetic counseling, prenatal diagnosis and carrier detection have become important issues. The pathogenesis of early- and late-onset agammaglobulinaemia is heterogeneous and usually not within the B-cell lineage. Patients with agammaglobulinaemia mainly suffer from infections caused by pneumococci or encapsulated Haemophilus influenzae located in the respiratory tract, paranasal sinuses, ears and meninges. Other prominent infections are Campylobacter jejuni bacteraemia and Giardia lamblia infection of the intestine. Among the more rare infections are those caused by Ureaplasma and Mycoplasma hominis. There is quite a number of non-infectious abnormalities which bother agammaglobulinaemic patients, especially those with late-onset agammaglobulinaemia. Of these, gastric carcinoma and intestinal lymphoma in late-onset agammaglobulinaemia and colorectal cancer in X-linked agammaglobulinaemia are the most dramatic. Life-threatening bacterial infections can largely be prevented by immunoglobulin substitution, even at relatively low dosages. However, insufficient immunoglobulin substitution is associated with recurrent airway infection and cumulative damage to the respiratory tract. for adequate substitution, efficacieous and safe intravenous immunoglobulin preparations are available. For selected patients (children, adults with poor venous access, and those experiencing side-effects on intravenous immunoglobulin), 16% immunoglobulin can be given by the subcutaneous route. With optimal substitution and--in the case of infection--adequate antimicrobial treatment, these patients have a good prognosis.

Active immunization against measles, Haemophilus influenza B, tetanus, diphtheria, hepatitis B, influenza, poliomyelitis, and, when indicated varicella and pneumococcus induces long-lasting immunologic protection in most healthy pediatric vaccine recipients. Among children receiving immunosuppressive therapy for cancer, possible early loss of specific immunity acquired from prior vaccination or disease, and likely diminished responsiveness to initial or booster vaccination must be considered. In addition, the safety of vaccine administration requires separate study in this population. Published evidence demonstrates preservation of vaccine-induced antibody titers against tetanus, diphtheria, poliomyelitis and (in children treated for lymphoma) pneumococcus. In contrast, prior immunity to varicella, influenza, and hepatitis B (when naturally acquired), and measles (acquired by vaccination) is compromised during and/or after antineoplastic therapy. Studies of immunologic protection acquired by prior vaccination against hepatitis B, varicella, and H influenza have not been published. The safety of administering toxoids and inactivated vaccines in this population is well documented. In contrast, morbidity must be expected if live attenuated vaccines (oral polio vaccine, attenuated measles vaccine or attenuated varicella vaccine) are administered to children receiving anti-cancer therapy. The risks of using live vaccines should be measured against demonstrable benefits in any vaccine program. The response to initial or booster immunizations against tetanus and diphtheria are similar to those in healthy children. For all other immunizations reviewed, responsiveness is diminished during periods of chemotherapy, more strikingly in children treated for leukemia than for solid tumors. Antibody responses to these vaccines range from slightly blunted (in the case of H influenza B) to marginal (influenza) or completely useless (pneumococcus and hepatitis B in children treated for leukemia).

Accelerated granulocyte and platelet recovery following peripheral blood stem cell transplantation (PBSCT) are well documented. We hypothesize that functional immunity may also be enhanced in PBSCT and performed a phase II trial of immunizations in patients with lymphoma undergoing autologous transplantation with peripheral blood stem cells or bone marrow. Seventeen BMT and 10 PBSCT recipients were immunized at 3, 6, 12, and 24-months post-transplantation with Haemophilus influenzae type b (HIB)-conjugate and tetanus toxoid (TT) vaccines. IgG anti-HIB and anti-TT antibody concentrations were measured and compared between the two groups. Geometric mean IgG anti-HIB antibody concentrations were significantly higher for PBSCT recipients compared to BMT recipients at 24 months post-transplantation (11.3 micrograms/ml vs 0.93 microgram/ml, P = 0.051) and following the 24 month immunization (66.2 micrograms/ml vs 1.30 micrograms/ml, P = 0.006). Similar results were noted for IgG anti-TT antibody with significantly higher geometric mean antibody concentrations in the PBSCT group at 24 months post-transplantation (182 micrograms/ml vs 21.6 micrograms/ml, P = 0.039). Protective levels of total anti-HIB antibody were achieved earlier in PBSCT recipients compared with those of BMT recipients. PBSCT recipients had higher antigen-specific antibody concentrations following HIB and TT immunizations. These results suggest enhanced recovery of humoral immunity in PBSCT recipients and earlier protection against HIB with immunization.

With changes in the demographics of human immunodeficiency virus (HIV) infection, women and children are becoming the fastest growing group of newly infected patients. With longer survival after HIV infection, more women infected with HIV are becoming pregnant. Pulmonary disease is one of the most common presenting conditions in an AIDS-defining illness. Pneumocystis carini pneumonia and tuberculosis are the most common disorders that herald the onset of AIDS. They are also the most frequently encountered HIV-related pulmonary complications during pregnancy. Others have been rarely reported during pregnancy and include fungal infections (Cryptococcus neoformans, Histoplasma capsulatum, and Coccidioides immitus), bacterial infections (Haemophilus influenzae and Streptococcus pneumoniae along with Pseudomona aeruginosa), viral infections (CMV), opportunistic neoplasms (Kaposi's sarcoma, lymphoma) and miscellaneous conditions peculiar to HIV-infected individuals (nonspecific interstitial pneumonitis, lymphoid interstitial pneumonitis, isolated pulmonary hypertension, and pulmonary edema secondary to cardiac disease or drug abuse). Most of the data regarding the pulmonary complications of HIV infection come from studies in nonpregnant patients. The extent to which pregnancy affects the course of respiratory disease in HIV infection and vice versa is not well documented. Clinical presentation is usually not altered by pregnancy. Except for minor modifications mainly related to potential fetal effects, the diagnostic work-up and management are similar to those in the nonpregnant patient. The most important effect of pregnancy on these conditions remains the delay in diagnosis and treatment. A high index of suspicion should, therefore, be maintained. In addition, most prophylactic measures recommended in nonpregnant HIV-infected individuals also apply to pregnant women.

We reviewed the long-term survival, treatment-related mortality and morbidity of a continuous cohort of patients with Hodgkin's disease diagnosed and staged at the Haematology unit of the Belfast City Hospital between January 1973 and October 1992. The analysis included a comparison of the survival of those patients who were entered into BNLI (British National Lymphoma Investigation) trials compared to those not entered during this 20 year period. In addition univariate and multivariate analysis of prognostic factors was performed. The complete remission rate (CR) was 79.6% with a 15 year survival of 55.3%. On multivariate analysis in which deaths due to active Hodgkin's disease only were considered age > 50 emerged as the most significant prognostic factor (P < 0.0007), the presence of B symptoms also having independent significance (P = 0.008). Trial status did not have any independent prognostic significance. Eighty one deaths occurred: active Hodgkin's disease (50), second malignancy (9), treatment-related (10), unrelated (9), unknown (3). This long-term follow up study provides useful information additional to the data produced by clinical trials which are biased by selection criteria. The occurrence of Haemophilus Influenzae meningitis in a patient 17 years following splenectomy highlights the need for appropriate vaccination of patients splenectomised for Hodgkin's disease.
