Acute glomerulonephritis developed in a man with pneumococcal pneumonia. Serum complement studies revealed decreased levels of C4, properdin, and C3. Renal immunofluorescence studies demonstrated pneumococcal antigen, C1q, C4, C3 proactivator, properdin, C3, IgG, and IgM. Circulating cryoglobulin contained pneumococcal antigen and antibody, C3, and immunoglobulins. Serial pneumococcal antigen and antibody levels did not display patterns that were characteristic of classical immune elimination, but the patterns may have been influenced by the reentry of antigen. A diffuse, pulmonary alveolitis also developed in the patient. Lung immunofluorescence studies revealed pneumococcal antigen, IgG, and C3 in alveolar walls and capillary basement membranes. The glomerulonephritis and alveolitis resolved after a prolonged course. These findings provide presumptive evidence for pneumococcal, immune complex glomerulonephritis with complement activation via both classical and alternative pathways and suggest an immunologic pathogenesis for the pulmonary alveolitis.

The course of disease of a patient with membranoproliferative glomerulonephritis and partial lipodystrophy is described. The case is further characterized by a deficiency of C3 and C3- activator, by normal values of C4, by evidence of the nephritogenic factor, by raised fibrin degradation products and by an unselective proteinuria. The course of the glomerulonephritis runs parallel to a pronounced susceptibility to infection (at first varicella, tonsillitis and measles, later pneumonia, meningitis, encephalitis and hepatitis). On account of a nephrotic syndrome and an initative impairment of the renal function, a cytostatic treatment was begun, which although raising the C3 level did not influence the further course of the disease. As the patient has a healthy identical twin sister without lipodystrophy, who shows no reduction in C3 and no nephritogenic factor, this case proves that these diseases are acquired and not genetically determined.

A severe staphylococcal septicemia originating from an unknown focus occurred in a 17-year-old patient who had undergone a Rastelli-Ross operation 5 years earlier. The clinical course was complicated by extensive bilateral pneumonia, diffuse intravascular coagulation, and glomerulonephritis. After 4 weeks of intensive conservative treatment, including a daily regimen of 16 Gm. of cloxacillin, the patient was operated upon for a rapidly progressive false aneurysm, which had resulted from dehiscence of the anastomosis between the prosthesis and ventricle. The excised prosthesis proved to be sterile. The postoperative course was uneventful. Cloxacillin treatment was continued for 6 months, initially parenterally and later orally. After discontinuation of therapy, no signs of infection have occurred. Right-sided intracardiac or intravascular prosthetic material may be particularly susceptible to infections originating from the body surface.

Histologic and immunopathologic studies were performed at autopsy on the kidneys of a patient in whom hematuria and proteinuria developed in association with cytomegalovirus (CMV) pneumonitis. Light microscopic examination of the kidneys revealed focal mesangial proliferative glomerulonephritis. Immunofluorescent microscopy revealed a granular deposition of IgG, IgA, C3, and C4, mainly in the mesangium. CMV antigens were also demonstrated in a similar immunofluorescent pattern. Glomerulus-bound immunoglobulins were eluted and demonstrated to contain antibodies to CMV antigens. These findings suggest that in some patients who have CMV infection immune-complex glomerulonephritis is induced by glomerular deposition of CMV antigen-antibody complexes.

A large number of bacterial species are causative agents of respiratory tract disease. The discussion will center on three infections selected because they represent different problems in control on the basis of epidemiologic and immunochemical factors. Group A hemolytic streptococci are common upper respiratory tract pathogens which may initiate severe non-suppurative sequelae such as rheumatic fever and glomerulonephritis. Recent progress concerning M protein vaccines will be reviewed. Pneumococci are still the most frequent cause of pneumonia at all ages. Pneumococcal vaccines are the prototype for purified polysaccharide vaccines since their effectiveness was demonstrated 30 years ago. The major problem in vaccination is the very large number of capsular serotypes. Pseudomonas aeruginosa represents the relatively new problem of gram-negative bacterial infections in the immunodepressed host. Demonstration of seven immunotypes as the cause of 90% of human infections has led to preparation of a multivalent vaccine composed of lipopolysaccharide antigens. Current knowledge of this vaccine will be discussed.

The kidneys of three patients who died of pneumonia due to Klebsiella pneumoniae were studied at autopsy by light and immunofluoerescent microscopy. One had no clinical evidence of renal disease; two had only microscopic hematuria and mild proteinuria. Light microscopy revealed focal proliferative glomerulonephritis in all three cases. Also in all three, immunofluorescent microscopy revealed a granular deposition of capsular polysaccharide antigens of Klebsiella pneumoniae in association with immunoglobulins and complement components in the mesangium and along the glomerular basement membrane. Furthermore, the glomerular bound immunoglobulins were eluted and demonstrated to contain antibodies specific to a capsular polysaccharide antigen of Klebsiella pneumoniae isolated from each patient. These findings may illustrate that the capsular polysaccharides of Klebsiella pneumoniae are antigenic, and that the immune complex deposition in the kidney during infection with this agent can be associated with renal morphological changes. Whether or not clinical evidence of nephritis occurs may depend on the characteristics of the infection and the host factors.

Medical complications associated with narcotic addiction include bacterial endocarditis, pneumonia, pulmonary embolism and renal disease. Renal disorders associated with pentazocine abuse are rarely reported. They vary with method of administration, dosage, and duration of abuse. We describe a 33-year-old male addict, using intravenous pentazocine for 6 years. He has nephrotic syndrome with a rapid deterioration of renal function to a uremic stage within 3 weeks. The laboratory data includes: IgG 1270 mg/dl, IgA 369mg/dl, IgM 326mg/dl, C'3 65.2 mg/dl, C'4 16.3 mg/dl, and serum soluble interleukin-2 receptor level (sIL-2R) greater than 6000U/ml. A renal biopsy revealed membranoproliferative glomerulonephritis (MPGN) type I with tubulointerstitial nephritis. Immunofluorescent (IF) study revealed granular deposition of C'3 and IgM in mesangium and the glomerular capillary wall. The pathogenesis of glomerular disease in drug addicts is discussed, and the literature reviewed.

The Drash syndrome, the first case in Thailand is reported. The patient had male pseudohermaphrodite, Wilms' tumor of the left kidney and mesangial proliferative glomerulonephritis. Metastasis of Wilms' tumor was noted in the liver, omentum, pelvic peritoneum and vertebral body. Chemotherapy (actinomycin D, vincristine and dexamethasone) and local irradiation were given. The patient developed pneumonia, diarrhea and ended up with Steven-Johnson syndrome from Cotrimoxazole hypersensitivity.

Adenovirus (AV) infection usually has a benign course in normal hosts; however, in immunocompromised patients, AV may cause pneumonia, cystitis, or disseminated disease with substantial morbidity and even mortality. Although pulmonic AV involvement is common, infection of the kidney is unusual. The histologic findings previously described include tubular necrosis with interstitial inflammation and glomerulonephritis. We report a case of an AV-induced unilateral mass lesion in the kidney of a patient with Hodgkin's disease (HD) following bone marrow transplantation.

Sphha/sphha anemic mice have an abnormality in the erythroid membrane protein, alpha spectrin, and exhibit multiple related clinical abnormalities, including spherocytosis, shortened red cell survival, chronic hemolysis, hemosiderosis, and extramedullary hematopoiesis. In addition, these mutant mice exhibit a granulocytosis and lymphocytosis, lymph node hyperplasia, elevated serum immunoglobulins, membranoproliferative glomerulonephritis, and decreased lifespan--abnormalities that are less clearly attributable to a spectrin defect. In order to further elucidate the mechanisms of disease in these animals, we undertook a series of bone marrow transplantation experiments. Transplantation of anemic marrow into lethally irradiated congenic +/+ mice resulted in chronic spherocytosis, hemolytic anemia, peripheral leukocytosis, and extramedullary hematopoiesis. Additionally, transplant recipients of anemic marrow which had received a higher radiation dose (12 Gy) had increased numbers of peripheral blood CD4+ and CD8+ lymphocytes, a hypocellcular thymus, and a severe pneumonitis characterized by nodular areas of consolidation and edema. Mice receiving congenic +/+ marrow and irradiated with the same radiation dose exhibited minimal pulmonary abnormalities. Anemic mice transplanted with congenic +/+ marrow usually died, but the survivors exhibited reversal of some clinicopathological changes. These results would suggest that the clinical abnormalities of sphha/sphha mice are in part attributable to abnormalities of hematopoietic stem cells but may also involve defects in other cell types. The pathogenesis of the accompanying lymphoid abnormalities observed in this mutant anemic mouse and any correlation with the erythroid spectrin defect are presently unknown. The pulmonary disease that develops in the transplant recipients of anemic marrow needs to be characterized further but may represent a unique model of lung injury.
