The inter-relationships of 25 variables in 140 rheumatoid patients were studied. One group, consisting mainly of hematologic variables, was differentiated on the basis of its high correlation with disease activity. The second group consisted of CRP and rheumatoid factor, which had highly significant positive correlations with each other. The third group consisted of serum aspartate aminotransferase, serum creatinine, antistreptolysin titre and blood eosinophils. These relationships are discussed.

During the last week of December 1989, an outbreak of respiratory system infection involved 32 hospital personnel and 2 patients was detected in Gazi University Medical Faculty Hospital. White blood cells count of the patients were either normal or there were a slight leucopenia. Throat cultures of the most patients were normal. Serum ASO, CRP, bilirubin, AST and ALT were usually within normal limits. According to symptoms, signs and laboratory data we considered a viral disease, especially influenza. All patients recovered without any sequelae. Of 34 in-patients, 8 paired sera, 2 acute phase sera, and 10 convalescent phase sera were tested for the presence of Hemagglutination Inhibition (HI) antibody to three influenza virus strains recommended by WHO in the 1989-1990 season: Influenza A/Taiwan/1/86 (H1 N1), Influenza A/Shanghai/11/87 (H3 N2), Influenza B/Victoria/2/87. All of the sera were negative for Influenza B/Victoria/2/87. There were no significant rises in HT antibody titer for Influenza A/Taiwan/1/86 (H1 N1). The sera for 4 of 8 patients examined both acute and convalescent phase sera had fourfold or greater rise in HI antibody for Influenza A/Shanghai/11/87 (H3 N2). Four patients examined only convalescent sera had 1/40 or greater rises in HI antibody for this influenza subtype. It was considered that this influenza outbreak was probably caused by Influenza A/Shanghai/11/87 (H3 N2).

We analyzed serum levels of interleukin-6 (IL-6) and seven acute phase proteins in CRP positive samples and in patients with open heart surgery. The concentrations of serum IL-6 were not correlated with other acute phase proteins in CRP positive samples. However, IL-6 were in inverse correlation with CRP, AAG, AAT and CER in patients with open heart surgery. These discrepancies were due to the differences in response time of each acute phase protein after the start of inflammation. Responses of acute phase proteins after open heart surgery were investigated from hour to hour. IL-6 increased rather rapidly than other acute phase proteins, and increases of CRP, TRF, AAT, AAG, CER, HAP and AMG followed. The time reached the peak were IL-6, CRP, TRF, AAT, AMG, AAG, HAP reached the peak in that order. IL-6 constantly increased seven hours earlier, and reached at maximum values forty three hours earlier than CRP in each case. The measurement of serum concentration of IL-6 may be useful for early detection of acute inflammation.

Serum IL-6 levels have been shown to correlate with disease severity and prognosis in patients with plasma cell dyscrasias. Among its pleiotropic actions, IL-6 is also the major regulator of the acute phase response in humans. The possible impact on survival of the major serum acute phase proteins (s.APP) [C-reactive protein (s.CRP), alpha-1-antitrypsin (s.AAT), haptoglobin, acid alpha-1-glycoprotein and alpha-2-macroglobulin (used as control)] was assessed on a population of 103 consecutive, previously untreated myeloma patients. Univariate analysis showed that among the acute phase proteins only s.AAT (P = 0.015) and s.CRP (P = 0.027) were significantly correlated with survival. The multivariate Cox proportional hazard model applied to s.APP and other common parameters showed that s.beta-2-microglobulin (s.b2M), s.calcium, s.creatinine, BM plasma cell percentage, age and s.AAT correlated significantly with survival. Combining s.b2M and s.AAT allowed stratification of myeloma patients: those with low levels of s.b2M (< or = 3 mg/l) and of s.AAT (< or = 3 g/l) presented an excellent prognosis (median survival exceeding 10 years) while those presenting higher values of the two parameters presented a median survival of 2.5 years (P = 0.002).

It is now quite well accepted that laboratory test results are indispensable or of primary significance to accurately diagnose a new patient's disease. Furthermore, most doctors recently find difficulty in appropriately selecting and ordering necessary but not excess laboratory tests and to read and interpret all the given test results correctly. In our hospital the system of the outpatient clinic will be changed basically on a specialty clinic system. In order to operate such a specialty clinic system effectively, it appears quite important to set up a unit to discriminate new unspecified patients properly and to consult them to an appropriate specialty clinic. As a preliminary trial, we opened a new patient clinic in July, 1992. The aim of this clinic is to accurately diagnose the new patients' disease immediately and to send them to the specialty clinic on the day of their first visit. Prior to history taking and physical examination by the attending doctor, the patients are instructed to take a set of laboratory tests. These include urinalysis, chest X-P, ECG, hematological examinations (RBC, WBC, Ht, Hb, PLT and ESR) and biochemical tests (AST, ALT, ALP, gamma GTP, LDH, CPK, Chol, T-Bil, TP, Alb, TG, BUN, Cr, Glu, Na, K, Ca, P and CRP). These results are transferred to the clinic within one hour so that the doctor is able to make the diagnosis effectively and to refer the patients to an appropriate clinic.(ABSTRACT TRUNCATED AT 250 WORDS)

There is no golden standard for the diagnosis of acute pancreatitis (AP). The diagnosis is currently based on clinical presentation, measurement of released pancreatic enzymes and imaging studies. Serum/urinary amylase, lipase and trypsinogen-2 dipstick are the most applicable methods in the clinical practice largely because of their simple, rapid, inexpensive and readily available assay methods. In addition to the clinical picture, inflammatory markers (CRP) or contrast enhanced CT can be used to assess the severity of acute pancreatitis. Multifactorial scoring systems (Ranson's prognostic signs, APACHE II, MOF-score) may be too cumbersome for clinical practice. Patient history, determination of AST, bilirubin and alkaline phosphatase levels as well as imaging studies such as ultrasonography and ERCP can be used to distinguish between biliary and non-biliary origin of the disease.

We studied the clinical and CT findings of 3 children with acute encephalopathy associated with adenovirus type 7 (AD-7) infection. Seizures in all the patients developed from 8 to 10 days after the onset of pyrexia. The values of serum AST, LDH and CRP elevated and those of WBC and serum protein decreased at the onset of encephalopathy. None of the patients had CSF leukocytosis. CT showed mild brain atrophy in all patients. A steroid pulse therapy was effective in one patient. The pathogenesis of encephalopathy is unknown. However, its onset and the success of the steroid pulse therapy suggested that it is a post infectious encephalitis. These findings, as well as the data of blood examination and of previous reports, implicated adverse effects of cytokines in the pathogenesis of this encephalopathy.

Reference values are usually based on blood samples from healthy men or non-pregnant women. Blood samples from pregnant women may be compared with these reference values. Correct references for pregnancy can be extremely important for clinical decisions such as ablatio placentae, appendicitis, premature rupture of membranes and preeclampsia. Previous studies of normal variations during third-trimester pregnancy are incomplete. Blood samples during pregnancy weeks 33, 36 and 39 as well as 1-3 h postpartum were collected from pregnant women with dietary iron supplement and at least one previous pregancy without a history of hypertension or preeclampsia. When the sampled values were compared with the present reference values from men and non-pregnant women, the following differences were found during normal pregnancy: Haemoglobin and ferritin were reduced, CRP was slightly elevated, WBC (white blood cell count) and HNL (human neutrophilic lipocalin) were elevated during pregnancy and significantly increased postpartum. Albumin was reduced. ALT and AST were slightly elevated and GGT was unchanged during pregnancy. ALP, D-dimer and fibrinogen were elevated. Uric acid increased during the third trimester and thrombocyte count decreased. Separate reference values for pregnant women are essential for correct diagnostic decisions during third-trimester pregnancy. Elevated levels of D-dimer do not necessarily indicate ablatio placentae. A diagnosis of progressive preeclampsia cannot be based on increasing uric acid levels and reduced platelet count in a stable clinical condition. HNL signals activation of neutrophilic granulocytes and can thereby offer a helpful tool for diagnosing infection during pregnancy and postpartum.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

An N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer carrier containing doxorubicin and human immunoglobulin as an actively/passively targeting moiety was used in four patients with generalized breast cancer resistant to standard cytotoxic chemotherapy. The dose and time schedule were deduced from a Phase I clinical trial in which doxorubicin bound to HPMA copolymer carrier (PK1) was tested. It was confirmed that the Dox-HPMA-HuIg conjugate is stable and doxorubicin remains in the peripheral blood with a small amount also in the urine, mostly in its polymer-bound form. More than 116 biochemical, immunological and hematological parameters were determined for blood samples taken from patients 24 h, 48 h, 72 h and 1 to 11 weeks after treatment. Depending on the patient, some parameters decreased permanently or temporarily to the normal level (CRP, C3, CA 72-4, beta(2)-microglobulin, ferritin, CEA, CA 125, CD4, CD8, CE19, CD16(+)56(+), leu, ery) and some moved markedly towards physiological values (AST, ALT, ALP, GMT, CA 15-3, NSE, AFP). While the number of peripheral blood reticulocytes was significantly decreased after treatment with the classical free drug, their number was not affected or was even elevated after treatment with Dox-HPMA-HuIg. Increased absolute numbers of CD16(+)56(+) and CD4(+) cells in the peripheral blood and activation of NK and LAK cells in all patients support data obtained in experimental animals, pointing to a dual, i.e. cytostatic and immunomobilizing character of Dox-HPMA conjugates containing a targeting immunoglobulin moiety.
