Reactional leprosy is studied according to its clinical forms A) Lepromatous a) Acute lepromatization: encroaching and invasive nature; the patient becomes more and more lepromatous ; bad prognosis. b) Erythema nodosum: "contusiform dermatitis"; variable prognosis not so bad as it is in the preceding case; allergic nature and its evolution is usually detained and therapeutics efficient. c) Erythema multiform. d) Lucio's phenomenon: vascular lesions and consequently necrosis as a complication of the "erythema necrotisans" (beautiful leprosy). B) Tuberculoid Reactional tuberculoid is the only one in this benign type, the Mitsuda's test must always be positive and prognosis consequently good. C) Dimorphous or "Borderline" whose Mitsuda's test is mostly negative, sometimes positive, but not stable. The lesions may stimulate the tuberculoid leprids but they invade mucous membranes, are impregnated by pigmentation, may present the Unna's band, and other characteristics of the Lepromatous type. Are associated (fever, asthenia and emaciation). Prognosis not very good, because of the possibility of lepromatization, according to its tendency. Evolution slower and frequent relapses. Besides there are nodular lesions. Pathogeny 1) Perifocal allergic reaction (Jadassohn). Similar to epituberculosis and Herxheimer reaction. 2)
Septicemia
. Sensitized tissues inside or outside the lesions, are invaded by the bacilli and so the allergic reaction takes place. Even without culture resources, Mycobacterium leprae has been found in the blood by direct examination. 3) Autoimmunization (Waldenstrom, Matthews and Trantman, 1965). Based upon the similarity between both humoral syndromes, in leprosy reactions and collagenous, diseases, as to: hypergammaglobulins, hypercryoproteins, antigammaglobulins, serological reactions (Wassermann, Kahn, Kline, VDRL) positives, Antistreptolysin O,
protein C
reactive, antinuclear factors, latex and Wadler-Rose test positives (rheumatoid tests) lowering of complement. If leprosy reaction is like this, it should be the less agressive of the autoimmune diseases. a) Its eruptions are cyclic not of long standing duration, as a general rule. b) Its prognosis has been recognized as good, except lately, because of the use of corticoid therapy which has been fatal, in many cases. After some years the leprosy reaction cures spontaneously. Treatment (see article)

We have studied the behaviour of total protein S, free protein S,
protein C
and C4b-binding protein fifteen neonates with severe infections, eight with septic shock and in a group of ten healthy newborns. Protein C was decreased in shock and septic patients, but only the shock group showed significant differences compared to normal neonates. Total protein S was normal in both groups of patients, although free protein S had significantly lower values in shock and nonshock infants. C4b-binding protein was higher than normal in septic and shock patients compared to the control group. Decreased values of
protein C
and free protein S can be explained by the activation of coagulation and their subsequent consumption. On the other hand, the increased levels of C4b-binding protein can affect the distribution of protein S in plasma, producing a shift in protein S to the complexed inactive form. These findings can contribute to an increased risk of microthrombosis during neonatal
sepsis
.

We present a patient with left ventricular thrombus diagnosed by two-dimensional echocardiography. Thrombosis was due to acquired transient
protein C
deficiency which was caused by impaired liver function due to hepatitis,
sepsis
and heart failure. With proper treatment the thrombus disappeared on the fourth day. Eighteen weeks later the
protein C
level returned to normal. We recommend echocardiographic evaluation and follow-up of suspected cases for intracardiac thrombus. The measurement of
protein C
level in such cases is proposed. This is the first case with left-sided cardiac thrombus associated with
protein C
deficiency in the medical literature.

Protein C, a potent vitamin K-dependent protein activated by an endothelial cell cofactor, thrombomodulin, has anticoagulant and profibrinolytic activity. Free protein S, a cofactor for
protein C
, potentiates
protein C
activity at the endothelial cell surface. Pulmonary thromboemboli are a consistent finding in adult respiratory distress syndrome (ARDS). To determine if protein S or
protein C
were affected by widespread endothelial cell damage in ARDS, we measured bound and free protein S levels and
protein C
antigenic and functional levels in 18 patients with acute lung injury, 6 critically ill patients without lung history, and 22 normal subjects. Free (PS:F) and bound (PS:Ag) protein S and
protein C
antigen (PC:Ag) levels were measured using an enzyme-linked immunoassay and
protein C
function (PC:Fn) by measuring its anticoagulant activity. We found a significant decrease in bound and free protein S levels of both patient groups in comparison to normal and a shift toward the inactive, bound protein S form. In addition, a significant decrease in free protein S compared to bound protein S in both patient groups was observed. While both PC:Ag and PC:Fn were significantly reduced compared to normal, the PC:Fn was significantly and severely decreased out of proportion to the PC:Ag in both patient groups. There was no difference between those with and without lung injury for both protein S and
protein C
. Analyzed according to etiology of lung injury, there was no difference in the bound and free protein S, nor in PC:Ag and PC:Fn levels between patients with
sepsis
and trauma. However, there were significant decreases in both protein S and
protein C
levels compared with normal subjects. Levels of both PS and PC levels in patients who survived did not differ from those who died. In summary, our data show that both protein S and C are markedly deranged in acutely ill patients who suffered from either
sepsis
or trauma, and these changes are independent of lung injury. The marked reductions in functional activity of PS and PC may be contributing factors to the thromboembolic complications often observed in these patients.

Sepsis
is often associated with hemostatic dysfunction. This study aimed to relate changes in fibrinolysis and coagulation parameters to
sepsis
and
sepsis
outcome. Urokinase-type plasminogen activator (u-PA) antigen, tissue-type plasminogen activator (t-PA) antigen and activity, plasminogen activator inhibitor (PAI) type 1 antigen, PAI activity, antithrombin (AT) III activity, and
protein C
activity were measured in 24 patients suffering from
sepsis
or septic shock and the results were compared with those observed in 30 non-
sepsis
patients with severe infectious disease. The u-PA level was markedly increased in plasma of
sepsis
patients as compared to non-
sepsis
patients (11.5 +/- 9.4 versus 1.6 +/- 1.5 ng/ml, p less than 0.0001). PAI-1 antigen and t-PA activity showed a significant increase in
sepsis
patients (320 +/- 390 ng/ml versus 120 +/- 200 ng/ml, and 3.0 +/- 3.6 IU/ml versus 1.0 +/- 0.7 IU/ml, respectively, p less than 0.01). AT III was decreased in
sepsis
patients (58 +/- 28% in
sepsis
versus 79 +/- 26% in severe infectious disease, p less than 0.01) as was
protein C
(30 +/- 18% versus 58 +/- 27%, p less than 0.001). No significant difference was found for t-PA antigen nor for PAI activity. Nonsurvivors of
sepsis
were distinguished mainly by a high u-PA antigen level and increased t-PA activity. It is concluded that plasma u-PA antigen showed the strongest significant difference, among the parameters evaluated, between
sepsis
and severe infection. u-PA antigen may be of prognostic value in patients admitted to the medical intensive care unit for severe infectious disease.

Purpura fulminans is a rare disease characterized by purpura ecchymosis, hypotension, and fever associated with disseminated intravascular coagulation. It often begins as a benign infectious process and subsequently progresses to a severe, catastrophic outcome. It is recognized to originate from congenital or acquired
protein C
deficiency. We present an unusual case of an adult with Xanthomonas maltophilia
sepsis
that subsequently developed into purpura fulminans with involvement of the four extremities. We discuss the importance of the
protein C
system in coagulation homeostasis and its relationship to purpura fulminans.

The neonatal period is probably the only time when a higher incidence of spontaneous thromboembolic complications may occur in the otherwise normal healthy individual, and this may be related to the activation of the coagulation system at the time of parturition. This study was performed to look at the newborn coagulation and anticoagulation systems and compare these with the changes in the maternal circulation in normal cases. Paired umbilical cord venous and maternal venous blood samples were obtained and plasma levels of
protein C
, protein S, antithrombin III, fibrinopeptide A, fibrinogen, plasminogen, and fibrinolytic inhibitory activity were measured. The maternal plasma level was significantly higher in all cases except for fibrinopeptide A which was similar, and for fibrinolytic inhibitory activity which was lower (p less than 0.05). A significant correlation exists between maternal and newborn
protein C
levels (p less than 0.02) and fibrinolytic inhibitory activity (p less than 0.05). The findings indicate that parturition leads to a similar degree of activation of the newborn coagulation system as shown by the fibrinopeptide A level. As their anticoagulants and fibrinolytic activity levels are lower and the fibrinolytic inhibitory activity is higher, the newborns are thus predisposed to thrombosis even in the absence of complications such as
sepsis
.

Purpura fulminans (PF) is a cutaneous manifestation of a dramatic and deadly syndrome of systemic disseminated intravascular coagulation (DIC). It is characterized by microvascular thrombosis in the dermis followed by perivascular haemorrhage. Since two other related syndromes involve the
protein C
(PC) system, we undertook a serial study to investigate the levels of PC and protein S (PS) in two patients with acquired PF. Laboratory findings were consistent with DIC, and both patients were treated with blood replacement and heparin therapy. The levels of PC activity were very low during the initial 24-36 h after onset and gradually increased until returning to normal levels. The total and 'free' PS were also abnormal during the initial onset of PF. The total and free PS increased to normal after 4-6 d. Although the pathogenesis is not fully understood, the infection and
sepsis
appears to consume PC and PS selectively during the PF and DIC phase. Acquired PF appears to selectively involve the PC system in a similar fashion to two other syndromes of PF-like lesions.

Plasma fibronectin was measured with Laurell's immunoelectroassay in 44 patients with meningococcal
sepsis
. The average value (15.0 +/- 7.9 mg/dl) was lower than that in normal children (27.4 +/- 8.7 mg/dl) (p less than 0.001). Fibronectin in patients correlated positively with antithrombin III (AT-III) values (p less than 0.02), but not with
protein C
(0.05 less than p less than 0.1). The decrease of fibronectin had no prognostic value. The fibronectin levels were lower in patients with disseminated intravascular coagulation (DIC+), than in those without DIC (DIC-) (p less than 0.02), but were lower in both groups than in a normal control group. A negative correlation between fibronectin and
protein C
was only present in DIC- patients (r: -0.773 = p less than 0.01). Fibronectin varied independent of AT-III and
protein C
in DIC+ patients. The study was repeated in 11 patients 24 hours after admission when fibronectin had decreased in 7/11 cases (mean decrease: -2.7 +/- 8.7 mg/dl). This variation correlated in a negative way with AT-III (r: -0.659 = p less than 0.05). In meningococcal
sepsis
fibronectin decreases very early, even in DIC- patients and its relationship to AT-III and
protein C
is different, depending on the presence of DIC and on the stage of evolution of the disease.

Fatal multiple organ failure after severe infection may be related to an early activation of protease cascade systems. This study aimed to relate changes in coagulation, fibrinolysis, and kallikrein to shock and outcome. Of 53 patients with severe infection, 30 did not develop shock, 12 survived septic shock, and 11 died from organ failure after septic shock. No patient had overt disseminated intravascular coagulation. We measured 17 components of the coagulation/fibrinolysis/kallikrein pathways on admission and on the next 2 days. High values for fibrinogen, factor VIII:C, von Willebrand factor antigen, and D-dimer were seen in all patients; factor XII, prekallikrein, factor VII, antithrombin,
protein C
, and fibronectin were low. The patients thus appeared to be hypercoagulable. These disturbances were more pronounced in septic shock survivors, who also had low plasminogen and antiplasmin, indicating ongoing fibrinolysis. Nonsurvivors of
sepsis
were distinguished mainly by high plasminogen activator inhibitor values; this suggests an impaired functional fibrinolysis in fatal
sepsis
, with possible therapeutic implications. Cryoprecipitate infusion increased the fibronectin concentration, but did not influence the other factors studied.
