Over a 6 years period, 51 autopsies have been performed in infants dead after severe sepsis. One third of them had renal damages, consisting mainly in haemorrhagic infiltration. Pathological and clinical data are not always well correlated, but some parameters may enhance a poorer renal prognosis, such as the duration of shock and anuria, or exchange transfusion. The clinical presentation of the infection and the encountered germs are the same in both groups, with or without renal damage. A better management of intensive haemodynamic cares in these neonates increases their survival rate and raises the problem of chronic renal failure or hypertension in this situation. It seems very useful to state precisely the surveillance and protection of the renal function in such patients.

Classification of platelet disorders has been based on the platelet count. Addition of a second variable, mean platelet volume (MPV), to the routine blood count allows classification of patients into 9 categories: high, low, or normal MPV, and high, low or normal platelet count. We studied 1,244 adult inpatients. 1,134 had both platelet values normal. 11 patients had high MPV and low platelet count: all had hyperdestructive causes. 15 patients had high MPV and normal platelet count: 12 had heterozygous thalassemia, and three had iron deficiency. Seven patients had high MPV and high platelet count: causes included myeloproliferative disorders, inflammation, iron deficiency, and splenectomy, 25 patients had high platelet counts and normal MPV: the causes were inflammation, infection, sickle cell anemia, iron deficiency, or chronic myelogenous leukemia. 52 patients had an MPV that was inappropriately low for the platelet count (high, normal, or low). All had sepsis, splenomegaly, aplastic anemia, chronic renal failure, or a disease being treated with myelosuppressive drugs. High MPV thus appears correlated with myeloproliferative disease or thalassemia; and low MPV, with cytotoxic drugs or marrow hypoplasia. Addition of MPV to the platelet count allows subtler disorders to be detected (when the platelet count is normal), and allows distinction of the cause of thrombocytopenia.

60 Jamaican children with homozygous sickle cell (SS) disease underwent splenectomy, 14 for prophylaxis against recurrent acute splenic sequestration and 46 for treatment of sustained hypersplenism. Age at operation varied from 9 months to 16 years. Patients were followed up for 1 month to 27 years (median 6 years), with a total of 369 years of patient-observation. None of the 3 patients who died, at ages 2 1/2, 6 1/2, and 21 years, had received prophylaxis against infection. Overwhelming sepsis was possible but not confirmed in the first two deaths which occurred 11 months and 2 1/2 years after operation; the third died from chronic renal failure 11 years after splenectomy. After operation, there were no confirmed cases of pneumococcal septicaemia or meningitis, and the commonest clinical event was the acute chest syndrome.

Forty-two patients with advanced testis carcinoma without previous chemotherapy were treated with VAB-4, and 41 were evaluable. The program consisted of three in-hospital inductions 16 weeks apart, and outpatient treatments every three weeks. Of the patients, 80% achieved complete remissions (CR). Chemotherapy alone induced CR in 61%, partial remissions (PR), in 24% and minor response (MR), in 15%. An additional 20% of patients (six PRs and 2 MRs) achieved CR following resection of residual tumor deposits. With a median follow-up of 27 months, the median duration of CR has not been reached. Of those achieving CR to chemotherapy alone, 12% had relapses. Bulk and extent of metastatic disease, histology of primary tumor, and tumor markers at the beginning of therapy influenced the frequency of CR. Of those with minimal disease, 90% achieved CR. The CR rate was 67% for those with advanced thoracic disease and 29% for those with advanced abdominal disease. Patients who had embryonal carcinoma and those who had no elevation of alpha-fetoprotein had a higher frequency of CRs. Myelosuppression with a leukocyte count drop less than 1000/mm3 occurred in three patients, and no patient had chronic renal failure or pulmonary fibrosis. One patient died from sepsis while in complete remission.

In uremic intoxication proteolytic activity in plasma and striated muscle is enhanced. To get further insights into the underlying mechanisms the lysosomal factors of polymorphonuclear (PMN) leukocytes and the plasma elastase-alpha 1-proteinase inhibitor complex were investigated in patients with acute and chronic renal failure. Lysosomal activity was evaluated in peripheral blood smears by the lysis of erythrocytes and plasma (halo formation) around each neutrophil induced by 0.25 M NaC1 borate buffer. In about half of the patients with chronic renal insufficiency on dietary treatment lysosomal activity of PMN leukocytes was reduced. The plasma concentration of elastase-alpha 1-proteinase inhibitor complex was normal in most subjects, but increased in three patients with the highest serum creatinine levels (greater than 13 mg/d1). In the patients with acute renal failure (ARF) of various origin (postoperatively, septicemia, pancreatitis, or dye-induced) halo formation was either reduced or absent. The plasma elastase-alpha 1-proteinase inhibitor complex was increased in 5/6 of the patients by a factor of two to four. Also in the patients on regular hemodialysis treatment halo formation of PMN leukocytes was substantially reduced, whereas the plasma levels of elastase-alpha 1-proteinase inhibitor complex was slightly increased. The finding of reduced lysosomal activity of PMN neutrophils in uremia may be partly due to an enhanced release of neutral proteinases into the circulation as indicated by the elevated plasma levels of elastase-alpha 1-proteinase inhibitor complex in some patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A nephelometric method is described for determination of plasminogen and two types of plasmin inhibitors in human plasma having different affinity toward plasmin. This method is based on the kinetic analysis of effects of whole plasma and plasmin inhibitor fraction obtained from plasma on the activity of exogenously added plasminogen which was determined by measuring the decrease of light scattering of fibrin suspension. With this method we have determined the activity of plasminogen and two types of inhibitors in the plasma of normal subjects and patients with high fibrinogen degradation product values. They include patients with various malignant tumors with DIC, chronic renal failure, sepsis, vascular diseases, and liver cirrhosis with hepatoma.

The incidence of nonobstructive colonic dilatation (NCD) is unknown, but the attendant mortality associated with perforation is nearly 50%. Patients with chronic renal failure and transplant recipients may manifest many of the conditions that have been implicated in the development of NCD. Mechanical obstruction and ischemic bowel disease must be eliminated as causes for colon dilatation. Over a four-year period eight patients (mean age 50 years) were treated for presumed NCD. Six patients with a mean cecal diameter of 12.8 cm were treated initially with colonoscopy. Five patients (83%) had successful endoscopic decompression; of the three remaining patients, one underwent urgent ileocolectomy for cecal ischemia after unsuccessful endoscopic decompression, a second (cecal diameter 13 cm) had a tube cecostomy performed as an initial procedure, and the third (cecal diameter 9 cm) was managed successfully with enemas and nasogastric suction. Two deaths occurred in the series (25%), but both were unrelated to colon distension. No complications of colonoscopy were observed. The sequelae of massive NCD (cecal ischemia, perforation, and protracted sepsis) are poorly tolerated in the immunocompromised patient. Conservative management may be employed in patients with a cecal diameter of 9 cm, but urgent diagnostic and therapeutic colonoscopy is recommended for patients with a cecal diameter of 12 cm or greater. Operative tube cecostomy may be necessary if colonoscopic decompression is unsuccessful or cannot be performed.

Hypertension, phosphate retention, hyperfiltration hyalinosis and the natural course of the underlying are well known factors leading to progression of chronic renal failure. Acute bacterial interstitial nephritis occurring in a previously diseased kidney, although well documented in experimental animals, has not been shown to aggravate chronic renal failure in man. We report on 3 cases of acute suppurative interstitial nephritis, due to E. coli urinary infection complicated by septicemia. All had rapid aggravation of previously mild renal failure secondary to chronic interstitial nephritis. Sepsis originated from the urinary tract which in 2 instances had been temporarily obstructed. Renal biopsy disclosed a diffuse interstitial infiltrate containing numerous polymorphonuclear leukocytes. This was superimposed on chronic tubular and interstitial lesions. In 1 case there were glomerular lesions with crescents and mesangial C3 deposits. A 2nd biopsy performed in 2 cases was of prognostic interest. In one case it showed active lesions and the necessity of continuing the treatment and in the other a satisfactory healing allowing cessation of therapy. Treatment was guided by antibiograms, the clinical and urinary signs of activity, renal biopsy findings and antibiotics known to be concentrated in renal tissue. The duration of treatment seemed important for the regression of acute renal lesions. Hematogenous bacterial interstitial nephritis should be considered as a possible cause of aggravation in chronic renal failure.

In uremic intoxication proteolytic activity in plasma and striated muscle is enhanced. To get further insight into the underlying mechanisms the neutral proteinases of polymorphonuclear (PMN) leukocytes were investigated in patients with acute and chronic renal failure. The following studies were performed: 1. Neutral proteolytic activity of PMN neutrophils in blood smears (according to Klessen, 1978). 2. Serum levels of elastase alpha 1 proteinase inhibitor complex (Neumann et al., 1981). In about half of the patients with chronic renal insufficiency on dietary treatment the proteolytic activity of PMN leukocytes (halo formation are due to digestion of erythrocytes and plasma) was reduced. The serum concentration of elastase alpha 1 proteinase inhibitor complex was normal in most subjects, but increased in 3 patients with the highest serum creatinine levels (greater than 13 mg/dl). In the patients with acute renal failure (ARF) of various origin (postoperatively, septicemia, pancreatitis or dye induced) halo formation was either reduced or absent. Serum elastase alpha 1 proteinase inhibitor was increased in 5/6 patients by a factor of two to four. Also in the 15 patients on regular hemodialysis treatment halo formation was substantially reduced, while the serum levels of elastase alpha 1 proteinase inhibitor complex was slightly increased. The finding of reduced proteolytic activity of PMN neutrophils in uremia is probably due to an enhanced release of proteinases into the circulation as indicated by the elevated serum levels of elastase alpha 1 proteinase inhibitor complex in some patients. The release of proteinases might be in part due to the effect of "uremic toxins". In the RDT patients the contact of the blood with the dialyzer (cuprophane) membrane might be an additional factor. In the patients with ARF the underlying disease (infection, shock, trauma) contributes to the release of proteinases. These disturbances may be harmful for the patient, if the blood concentration or function of the most important proteinase inhibitors (alpha 1 proteinase inhibitor, alpha 2 macroglobulin) is reduced.

A case of multiple myeloma in a 41-year-old white man that resulted in chronic renal failure is discussed. During the period of hemodialysis treatment, remission of the patient's myeloma was induced by chemotherapy. Thereafter a transplanted cadaver kidney functioned well for 3.5 years despite episodes of sepsis, administration of nephrotoxic chemotherapeutic agents, and recurrence of the myeloma with intermittent excretion of Bence Jones protein in the urine. The results of this fully documented case, as well as two other cases we have previously reported, support the strategy of offering cadaver renal transplantation to carefully selected individuals who require long-term dialysis and whose myeloma is in remission after chemotherapy.
