Thirty-four children with Haemophilus influenzae type b meningitis were given prospectively either moxalactam (200 mg/kg/day) or ampicillin (400 mg/kg/day) plus chloramphenicol (75 mg/kg/day). One patient in each group died. The mean duration of fever, clinical response, sequential cerebrospinal fluid findings, and incidence of neurologic sequelae were similar between groups. Moxalactam cerebrospinal fluid bioactivity was significantly greater than that of ampicillin or chloramphenicol throughout therapy. Neutropenia, liver enzyme abnormalities, and diarrhea were not significantly different. In eight of 11 patients given moxalactam (versus one of 14 controls) there was complete elimination of gram-negative aerobic flora in the stools by day 10 (P = 0.002); however, none acquired Clostridium difficile. Moxalactam in effective therapy for H. influenzae type b meningitis.

Six children with chronic diarrhea and neutropenia, initially referred for evaluation of Shwachman-Diamond syndrome, were found to have no evidence of pancreatic insufficiency. All presented in the spring with a prodromal respiratory illness. Hematologic evaluation was normal except for iron deficiency anemia and neutropenia. Small intestinal biopsies of all children showed inflammation, consistent with chronic enteritis. The children were followed until growth returned to previous percentiles. Diarrhea and neutropenia resolved by 6-month follow-up, and there was no recurrence of the neutropenia at 1 year.

Two hundred bacterial septicemia occurring in neutropenic patients (PMN less than 1,000 microliter) were analyzed. Most of these patients had hematologic malignancies. The underlying disease, the degree of neutropenia the association of septic focus with the bacteremia, the responsive microorganisms and their evolution during hospitalization were studied as prognosis factors. The overall mortality was 32.5 p. 100. The mortality was higher in patients whose granulocyte count was lower than 500 microliter. The occurrence of major septic focus (pulmonary, perineal infection, diarrhea with abdominal distension, ORL, or cutaneous extensive focus) during bacteremia was a highly significant factor of bad prognosis. The mortality of bacteremias with and without major septic focus was respectively 62 p. 100 and 15 p. 100. A study of the distribution of the bacterias was performed in terms of mortality and duration of hospitalization. "Escherichia coli" and gram positive cocci were predominant during the two first days and mortality was then low. After that time, others Gram-negative bacterias appeared, especially "Pseudomonas aeruginosa" and the mortality was increasing until the twentieth day. Therefore, the authors raise the opportunity of antibiotic therapy according to the duration between the beginning of the hospitalization and the occurrence of sepsis in neutropenic patients. The role of the extensive use of a curative antibiotic association using colistine and nalidixic acid between 1974 and 1976 is discussed in the emergence of more gram positive cocci bacteremias between 1976 and 1978 than between 1974 and 1976 in the same intensive care unit.

A boy born healthy, developed gastrointestinal symptoms (diarrhea, vomiting, ulcerative stomatitis) and megaloblastic anaemia with thrombocytopenia and neutropenia at the age of five weeks. Serum levels of folate and cobalamin were normal, but there was cobalamin-mal absorption. In his serum apo-TC2 was not detectable and immunoreactive total TC2 was very low (10% of normal values). Cultured skin fibroblasts failed to secrete functioning TC2. Pharmacological amounts of parenteral Cyanocobalamin, administered regularly, led to hematological remission and normal development. Interruption of therapy was followed by relapse within a few weeks. A coexisting hypogammaglobulinemia did not respond to cobalamin therapy at the selected dose level. A family investigation of serum TC2 concentrations and the genetic TC2 variants in 7 persons of three generations yielded evidence of autosomal-recessive inheritance of a silent TC2 allele (TC2 QLFL SEA-like). Three persons with heterozygous deficiency were asymptomatic.

Fourteen infants with autoimmune neutropenia reported in the literature have been reviewed. Autoantibodies directed against their own neutrophils were demonstrated in the sera of these infants by agglutination, complement-dependent cytotoxicity, and immunofluorescence techniques. These antibodies were highly specific and were directed against antigens present on neutrophils. Among the currently known neutrophil antigens (NA1, NA2, NB1, NC1, NE1, ND1, 9A), antibodies reacting with either NA1 or NA2 have been identified frequently in the sera of infants with autoimmune neutropenia. Good correlation was demonstrated between the presence or absence of autoantibodies and the episodes of neutropenia in many cases. Antibodies from the patients also reacted with neutrophils from their parents and from normal unrelated volunteers when they shared the neutrophil-specific antigen against which the antibody was directed. Antibodies demonstrable by complement-dependent cytotoxicity appeared to detect different antigens which may also cause autoimmune neutropenia. Infants with this disorder were healthy at birth and for a few months afterwards, then became chronically ill with such symptoms as intermittent fever, diarrhea, and infections. Their hemoglobin levels, lymphocyte and platelet counts, and other immunological studies were normal except for severe to moderate neutropenia.

Colitis is a life-threatening complication of aplastic anemia which occurs during periods of profound neutropenia. Four cases of this previously unreported association are described here. A syndrome of fever, watery diarrhea, and generalized abdominal pain and tenderness occurred in close temporal relationship to development of severe neutropenia (less than 50 neutrophils per cu mm). None of the patients had received antibiotics, nor had a history of previous episodes of colitis. Three had cultures positive for colonic organisms during the episodes. In only one instance was the correct diagnosis made without operation. Gross evidence of disease was found in the cecum, the transverse colon, and rectosigmoid in three patients, but the true extent of disease was underestimated. Microscopic examination of the two resected specimens showed extensive mucosal and variable submucosal necrosis with invasion of the colonic wall by bacteria. Acute inflammatory changes were absent. With profound neutropenia, the colon wall lacks resistance to invasion by the resident microflora. The condition is probably best treated without operation. If first recognized at laparotomy, resection should be avoided.

Cefoxitin (CFX) was evaluated for its safety and efficacy in children. Fifteen patients were treated with 73-125 mg/kg per day of CFX by intravenous administrations. The diagnosis of the patients were acute pharyngitis (4), pneumonia (2), pertussis and pneumonia (1), urinary tract infection (3); and the remaining 5 patients were esteemed to have nonbacterial infections. All the 10 patients of bacterial infections were cured after the CFX therapy. The pathogens recovered were Streptococcus pyogenes (1), Streptococcus pneumoniae (3), Haemophilus influenzae (2), Escherichia coli (2), enteropathogenic Escherichia coli (1), and Klebsiella pneumoniae (1). All the strains isolated were susceptible to CFX, but the 2 isolates of Haemophilus influenzae had relatively high MIC values (12.5 mcg/ml). Diarrhea (3 cases) and transient neutropenia (1 case) were found to be associated with the CFX therapy. However, no severe adverse reactions were encountered. Half-life of the serum level was short (24.1 minutes) and excretion into the urine was rapid. CSF concentration obtained 30 minutes after an intravenous injection of 50 mg/kg of CFX in 1 case with inflamed meninges was considerably high (8.3 mcg/ml). CFX appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections.

Clinical efficacy of cefroxadine dry syrup, a new oral cephalosporin antibiotic, was evaluated in children, and the following results were obtained. 1. Three children were given a single oral dose of about 10 mg/kg of the drug when fasting, and its blood concentrations were determined. Blood concentrations were maximum at 30 approximately 60 minutes, i.e., 16.9 approximately 18.2 microgram/ml, and markedly low at 4 hours. 2. Thirty-six patients with the following diseases were tested with 23.1 approximately 44.4 mg/kg/day of the drug in 3 to 4 divided doses; 21 patients with lacunar tonsillitis, 2 with tonsillitis, 1 with scarlet fever, 4 with bronchitis and tonsillitis, 2 with cystitis, 4 with pyelonephritis, 1 with impetigo and 1 with probable Mycoplasma pneumonia. An overall efficacy rate in 35 patients excluding the last mentioned case was 91.4%, i.e., excellent in 20, good in 12 and poor in 3, and an eradication rate of the causative organisms was 88.9%. 3. Adverse reactions noted were diarrhea in 1 patient, eruption and diarrhea in 1 transient neutropenia in 1, eosinophilia in 3 and an elevation of GOT and GPT in 1. None were significant. 4. Taste and flavor of the drug was considered to be well palatable to children. 5. Taking into consideration of the results of fundamental evaluation of the drug, cefroxadine dry syrup is considered to be a potent new antibiotic in children, and the recommended dose will be 10 mg/kg 3 to 4 times a day.

Five eight week old dogs were inoculated orally and intranasally with cell culture origin canine parvovirus. Three dogs became depressed and anorectic and developed a mild (one dog) to severe diarrhea five days postinfection. The remaining dogs had subclinical infections but developed a lymphopenia followed by a transient lymphocytosis. The ill dogs developed mild (one dog) to severe neutropenia and a moderate lymphopenia. One died nine days postinfection. Recovery was associated with cessation of viral excretion and with lymphocytosis and antibody production. Two of three dogs challenged intragastrically developed mild clinical signs and a moderate panleukopenia four to eight days postinfection. The pathological changes of the experimental disease were very similar to that of spontaneous disease. Bone marrow changes included a severe granulocytic and mild erythroid depletion. The pathogenesis of canine parvovirus infection is discussed.
