In a prospective study of critically ill hypothyroxinemic we assessed the relationship between serum TSH and T4 during the return of serum T4 to normal during recovery. In this longitudinal study of 60 patients with a variety of critical illnesses, including burns,
septicemia
, and acute renal failure, serum T4 fell to less than 2.7 micrograms/dl (35 nmol/liter) in 24 patients, of whom 14 survived with return of T4 to normal. A rise in total T4 of more than 1.9 microgram/dl (25 nmol/liter) within 96 h occurred 13 times in 10 patients, while 4 patients had slower increases in T4. All 13 episodes of rapid T4 rise [1.7 +/- 0.8 (+/- SD) to 5.6 +/- 2.1 micrograms/dl] were associated with a marked increase in serum TSH (1.1 +/- 0.8 to 7.0 +/- 5.2 mU/liter), and TSH was transiently above normal during 8 episodes of T4 recovery. In the 6 episodes with sampling less than 6 h apart, the TSH rise consistently preceded the T4 rise. In the 4 patients who received dopamine, TSH and T4 remained low until cessation of therapy. During the TSH rise, only minor changes, which could not account for the increase in total T4, occurred in T4-binding globulin (12.9 +/- 3.3 to 14.8 +/- 3.3 mg/liter),
prealbumin
(208 +/- 73 to 234 +/- 82 mg/liter), and albumin (28.3 +/- 2.9 to 31.9 +/- 2.9 g/liter). Mean free T4 increased (0.60 +/- 0.34 to 1.45 +/- 0.56 ng/dl), as did total T3 (16 +/- 14 to 76 +/- 44 ng/dl), during the phase of TSH rise, suggesting that the increase in TSH was not simply a consequence of diminished negative feedback due to increased plasma binding. The very close and consistent temporal relationship between TSH and T4 during the recovery phase suggests that TSH may have an essential role in the return of T4 to normal during recovery from critical nonthyroidal illness.

The simultaneous changes in serum
prealbumin
, orosomucoid (alpha-acidglycoprotein, AGP), and C-reactive protein (CRP) were evaluated in 36 newborn infants with
septicemia
(n = 20), meningitis (n = 10), arthritis (n = 5), and peritonitis (n = 1). In 29 patients with a favorable outcome the values for serum
prealbumin
and CRP showed a rapid return toward normal: in 2 to 3 days serum
prealbumin
increased by 84% from the basal value and remained at (mean +/- 1 SD) 0.11 +/- 0.02 gm/L. Serum CRP decreased from 85 +/- 75 mg/L (range 0.15 to 206 mg/L) to 49 +/- 64 mg/L (2 to 210 mg/L) at 3 to 4 days of evolution and to normal values at day 13 to 16. The changes in serum orosomucoid values were slower, from 1.33 +/- 0.75 gm/L to 1.16 +/- 0.75 gm/L at day 13 to 16, with normalization after 20 to 30 days. Serum orosomucoid values returned to the normal range with the clinical improvement. In some patients the orosomucoid/
prealbumin
ratio decreased earlier than the serum orosomucoid concentration. Seven patients died, and in four of these in whom at least three values could be determined serum CRP and orosomucoid remained very high, whereas serum
prealbumin
did not increase or subsequently decreased. These data show an inverse change in serum CRP and
prealbumin
concentrations in infected neonates. The immediate decrease in CRP reflects the effect of treatment, whereas the later decrease in serum AGP parallels the clinical course of the infection. Thus the determination of these proteins can help to guide the treatment of infection in newborn infants.

Serum immunoglobulins and some complement components (C1q, C3c, C4, factor B, C9) have been evaluated in 99 malnourished patients. The sole abnormality which seems related to protein calorie malnutrition is a C1q decrease significantly correlated to serum albumin, thyroxin binding
prealbumin
and retinol binding protein. The immunoglobulins modifications seem to be related to pathological conditions associated with malnutrition (
sepsis
, liver diseases).

A study of 214 neonates (with 87 premature infants) reveals that C-reactive protein (CRP), orosomucoid and
prealbumin
are the most interesting proteins for the diagnosis of neonatal
sepsis
and for studying its follow-up. Orosomucoid is high in 85% of bacterial infections and CRP in 75%. Early type strep B infections give often false negative results. The evolution of CRP and of
prealbumin
corresponds to the effects of treatment and the evolution of orosomucoid is parallel to the healing of the patients. The ratio orosomucoid/
prealbumin
allows an earlier appreciation of the healing.

Non-fasting plasma amino acids, proteins, anthropometric measurements, urea, and creatinine for 17 hemodialysis patients were compared with values in normal patients of similar age and sex. Values were characteristic for renal failure but with similarities to protein-energy malnutrition. Partial correlation coefficients, correcting for age and height, identified nutritional and non-nutritional factors. Plasma valine was the most correlated variable and was used to rank and group the patients. The group with valine less than 150 micrometers/liter had low values for 17 variables. Valine, isoleucine, leucine, threonine, asparagine, weight, and arm muscle circumference were interrelated and reflected malnutrition whereas fat correlated with calorie intake, and histidine and serine with protein intake. Taurine, aspartic acid, cystine, citrulline, urea, creatinine,
prealbumin
and retinol-binding protein were decreased in malnutrition but were higher than normal due to a loss of renal function. Fourteen variables, less affected by malnutrition, were changed by specific non-nutritional factors. Hemodialysis patients of long standing (1 to 11 years) apart from two patients with recurrent
sepsis
, were adequately nourished, but those on hemodialysis for less than 15 months, most of whom had previously received peritoneal dialysis, were malnourished. Malnutrition in dialysis patients was due to protein and energy deficiency enhanced by metabolic abnormalities of amino acids. Our study shows that plasma valine is interrelated with other nutritional variables and may be used to assess protein-energy malnutrition.

A prospective nutritional evaluation of 84 unselected patients admitted to a multidisciplinary ICU was performed using anthropometric measurements, creatinine height index (CHI), and serum protein assays. All values tested were significantly lower than those of 40 healthy controls. A matrix of correlation coefficients showed many similarities among the variables studied. Fatal outcome and poor prognosis indices, such as
sepsis
and renal failure, were analyzed separately. Anthropometric measurements and CHI were not different in the separate groups. Albumin (Alb) and transferrin (Tr) were not different in patients with or without
sepsis
. Retinol binding
prealbumin
was significantly higher in patients with renal failure. Thyroxin-binding
prealbumin
(TBPA) was significantly lower in all the groups. We emphasize the interest of this rapid turnover protein in evaluating nutritional status. We suggest: (1) a systematic nutritional assessment, and (2) an aggressive nutritional support in the ICU patient.

An acute depletion of plasma fibronectin or FN has been observed in critically ill, surgical, or trauma patients, but there is little information on the relationships between FN levels and the final outcome in such cases, and on the simultaneous behaviour of other serum proteins. The daily values of FN, antithrombin III, IgG, C3,
prealbumin
, and transferrin were monitored in 98 intensive care patients after major elective surgery or trauma. According to their clinical course, they were divided retrospectively into three groups. Group A (33 patients) had
sepsis
. Group B (31 patients) had nonseptic complications, and group C (34 patients) had no complications in the ICU. The individual, nadir levels of FN, AT III,
prealbumin
, and transferrin were lower (p less than 0.01) in the septic group A than in B and C. Within the septic group, the nadir levels of AT III, but not those of FN, were lower (p less than 0.01) in the 14 nonsurvivors than in the 19 survivors. The FN and AT III levels had returned at least temporarily to the normal range in the six ultimate fatalities from
sepsis
who survived for more than two weeks. In the septic group, transferrin showed the highest percentages of actually subnormal levels and differed from FN in this respect with p less than 0.05. Furthermore, all six proteins showed a significant overall pattern (p less than 0.01) of parallel variations. The results confirm other reports on the behavior of fibronectin in septic patients as a group, but it was not informative as to the individual outcome, and its reduction might be viewed as part of a general plasma protein depletion associated with acute septic disease. This pattern is probably attributable to a combination of intravascular consumption and an overall excess of protein catabolism over synthesis.

The authors submit the results of the follow-up of the dynamics of 10 acute stage plasma proteins (up to the 7th day) in two surgical model situations: 1. planned operation of colorectal carcinoma by an intraabdominal approach and 2. operation of extensive varicosities of the lower extremities. As reference groups 3. healthy subjects (blood donors) were used and 4. patients with developed postoperative
sepsis
. Based on the results, the authors provide evidence of the asset of some selected indicators they assessed such as transferrin,
prealbumin
, alpha-1 acid glycoprotein (orosomucoid) and C reactive protein, for the early diagnosis of postoperative septic complications.

The serum concentrations of 5 "nutritional" and 5 "acute phase" proteins were prospectively studied in 3 groups of newborns with nephelometric methods. Group A: 22 healthy breast fed term newborns aged 4 days; group B: 28 healthy enterally fed preterm newborns (mean gestational age 33.3 weeks); group C: 49 preterm newborns (mean gestational age 29.5 weeks) on parenteral nutrition (PN). Infants with surgical procedures,
sepsis
and liver or renal diseases were excluded. The serum concentrations of almost all proteins were similar or only slightly different among the 3 groups and never related to the weight and chronological or post-conceptional age. Only
prealbumin
, apolipoprotein A and B and C4 levels were significantly different between term and preterm newborns. Enterally fed preterm infants had lower concentrations of alpha 1 acid glycoprotein and higher albumin, transferrin and apolipoprotein A than PN fed infants. Since the observed differences were usually quite small, we suggest that--at least in clinical practice--common serum reference values of these proteins should be adopted for all healthy growing newborns, whether preterm or at term, enterally or parenterally fed. The inter-relationships between different proteins were studied. Four of the five nutritional proteins were highly correlated one with another and the same was observed for the 5 acute phase proteins. Nutritional proteins as a group did not correlate with acute phase proteins, with the only exception of alpha 1 acid glycoprotein and apolipoprotein A. Thus, the 2 groups of proteins seem to be regulated by different metabolic systems.

After trauma or
sepsis
, the liver undergoes a reprioritization of export protein synthesis with elevated production of some acute-phase reactants and reduced production of others. We have examined the effects of combinations of insulin and the counterregulatory hormones (dexamethasone, glucagon, and epinephrine), in the presence or absence of interleukin (IL)-6, on the production by isolated hepatocytes of the positive acute-phase proteins C-reactive protein, alpha 1-antichymotrypsin, alpha 1-acid glycoprotein, and haptoglobin, and the negative acute-phase proteins
prealbumin
and transferrin. The effect of IL-6 on the production of the above proteins was influenced significantly by insulin and all of the counterregulatory hormones. Significant three-way interactions as well as higher order interactions between the stress hormones and insulin were seen in the case of C-reactive protein. The results indicate that both positive and negative acute-phase proteins respond differently to insulin and the counterregulatory hormones and that the potential exists for the regulation of synthesis of individual acute-phase reactants by interaction between the cytokine network and the classical endocrine hormones.
