The extracellular versus intracellular mechanisms of inhibition of TCR-triggered activation in thymocytes by adenosine under conditions of inhibited adenosine deaminase. (1/193)

The absence or low levels of adenosine deaminase (ADA) in humans result in severe combined immunodeficiency (SCID), which is characterized by hypoplastic thymus, T lymphocyte depletion and autoimmunity. Deficiency of ADA causes increased levels of both intracellular and extracellular adenosine, although only the intracellular lymphotoxicity of accumulated adenosine is considered in the pathogenesis of ADA SCID. It is shown that extracellular but not intracellular adenosine selectively inhibits TCR-triggered up-regulation of activation markers and apoptotic events in thymocytes under conditions of ADA deficiency. The effects of intracellular adenosine are dissociated from effects of extracellular adenosine in experiments using an adenosine transporter blocker. We found that prevention of toxicity of intracellular adenosine led to survival of TCR-cross-linked thymocytes in long-term (4 days) assays, but it was not sufficient for normal T cell differentiation under conditions of inhibited ADA. Surviving TCR-cross-linked thymocytes had a non-activated phenotype due to extracellular adenosine-mediated, TCR-antagonizing signaling. Taken together the data suggest that both intracellular toxicity and signaling by extracellular adenosine may contribute to pathogenesis of ADA SCID. Accordingly, extracellular adenosine may act on thymocytes, which survived intracellular toxicity of adenosine during ADA deficiency by counteracting TCR signaling. This, in turn, could lead to failure of positive and negative selection of thymocytes, and to additional elimination of thymocytes or autoimmunity of surviving T cells.  (+info)

Nucleotide pool imbalance and adenosine deaminase deficiency induce alterations of N-region insertions during V(D)J recombination. (2/193)

Template-independent nucleotide additions (N regions) generated at sites of V(D)J recombination by terminal deoxynucleotidyl transferase (TdT) increase the diversity of antigen receptors. Two inborn errors of purine metabolism, deficiencies of adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP), result in defective lymphoid development and aberrant pools of 2'-deoxynucleotides that are substrates for TdT in lymphoid precursors. We have asked whether selective increases in dATP or dGTP pools result in altered N regions in an extrachromosomal substrate transfected into T-cell or pre-B-cell lines. Exposure of the transfected cells to 2'-deoxyadenosine and an ADA inhibitor increased the dATP pool and resulted in a marked increase in A-T insertions at recombination junctions, with an overall decreased frequency of V(D)J recombination. Sequence analysis of VH-DH-JH junctions from the IgM locus in B-cell lines from ADA-deficient patients demonstrated an increase in A-T insertions equivalent to that found in the transfected cells. In contrast, elevation of dGTP pools, as would occur in PNP deficiency, did not alter the already rich G-C content of N regions. We conclude that the frequency of V(D)J recombination and the composition of N-insertions are influenced by increases in dATP levels, potentially leading to alterations in antigen receptors and aberrant lymphoid development. Alterations in N-region insertions may contribute to the B-cell dysfunction associated with ADA deficiency.  (+info)

Quantification of extracellular and intracellular adenosine production: understanding the transmembranous concentration gradient. (3/193)

BACKGROUND: Inhibitors of adenosine membrane transport cause vasodilation and enhance the plasma adenosine concentration. However, it is unclear why the plasma adenosine concentration rises rather than falls when membrane transport is inhibited. We tested the hypothesis that the cytosolic adenosine concentration exceeds the interstitial concentration under well-oxygenated conditions. METHODS AND RESULTS: In isolated, isovolumically working guinea pig hearts (n=50), the release rate of adenosine and accumulation of S-adenosylhomocysteine (after 20 minutes of 200 micromol/L homocysteine), a measure of the free cytosolic adenosine concentration, were determined in the absence and presence of specific and powerful blockers of adenosine membrane transport (nitrobenzylthioinosine 1 micromol/L), adenosine deaminase (erythro-9-hydroxy-nonyl-adenine 5 micromol/L), and adenosine kinase (iodotubericidine 10 micromol/L). Data analysis with a distributed multicompartment model revealed a total cardiac adenosine production rate of 2294 pmol. min-1. g-1, of which 8% was produced in the extracellular region. Because of a high rate of intracellular metabolism, however, 70.3% of extracellularly produced adenosine was taken up into cellular regions, an effect that was effectively eliminated by membrane transport block. The resulting approximately 2.8-fold increase of the interstitial adenosine concentration evoked near-maximal coronary dilation. CONCLUSIONS: We rejected the hypothesis that the cytosolic adenosine concentration exceeds the interstitial. Rather, there is significant extracellular production, and the parenchymal cell represents a sink, not a source, for adenosine under well-oxygenated conditions.  (+info)

Diinosine pentaphosphate (IP5I) is a potent antagonist at recombinant rat P2X1 receptors. (4/193)

1. The antagonist activity of a series of diinosine polyphosphates (IpnI, where n=3, 4, 5) was assessed against ATP-activated inward currents at rat P2X(1-4) receptors expressed in Xenopus oocytes and studied under voltage-clamp conditions. 2. Diinosine polyphosphates were prepared by the enzymatic degradation of their corresponding diadenosine polyphosphates (e.g., Ap5A into Ip5I) using 5'-adenylic deaminase, and purified using reverse-phase chromatography. 3. Against ATP-responses at rP2X1 receptors, the potency order for antagonism was (pIC50): Ip5I (8.5)>Ip4I (6.3)>Ip3I (>4.5). Ip5I (10-100 nM) caused a concentration-dependent rightwards displacement of the ATP concentration-response curve without reducing the maximum ATP effect. However, the Schild plot was non-linear which indicated Ip5I is not a competitive antagonist. Blockade by micromolar concentrations of Ip5I was not surmountable. Ip4I also behaved as a non-surmountable antagonist. 4. Against ATP-responses at rP2X3 receptors, the potency order for antagonism was (pIC50): Ip4I (6. 0)>Ip5I (5.6)>Ip3I (>4.5). Blockade by Ip4I (pA2, 6.75) and Ip5I (pA2, 6.27) was surmountable at micromolar concentrations. 5. Diinosine polyphosphates failed to inhibit ATP-responses at rP2X2 receptors, whereas agonist responses at rP2X4 were reversibly potentiated by Ip4I and Ip5I. None of the parent diadenosine polyphosphates behave as antagonists at rP2X1 - 4 receptors. 6. Thus, Ip5I acted as a potent and relatively-selective antagonist at the rP2X1 receptor. This dinucleotide pentaphosphate represents a high-affinity antagonist for the P2X1 receptor, at which it acts in a competitive manner at low (100 nM) concentrations.  (+info)

The anticonvulsant BW534U87 depresses epileptiform activity in rat hippocampal slices by an adenosine-dependent mechanism and through inhibition of voltage-gated Na+ channels. (5/193)

1. The cellular and molecular actions of BW534U87 were studied using intracellular and extracellular recordings from the CA1 region of rat hippocampal slices and whole-cell voltage-clamp recordings of recombinant human brain type IIA Na+ channels expressed in Chinese hamster ovary (CHO) cells. 2. Normal excitatory and inhibitory postsynaptic potentials evoked in hippocampal slices were unaffected by BW534U87 or the adenosine deaminase inhibitor EHNA. However, epileptiform activity was depressed by BW534U87 (50 micronM) and this inhibition was reversed by the adenosine receptor antagonist 8-phenyl theophylline (8-PT, 30 micronM). EHNA (10 micronM) mimicked the effects of BW534U87. Furthermore, BW534U87 enhanced the inhibitory effects of exogenous adenosine on evoked synaptic potentials. BW534U87 (50 micronM) also voltage- and use-dependently inhibited action potentials elicited by current injection, independent of the adenosine system, since it was not affected by 8-PT. 3. In CHO cells expressing the recombinant human brain Na+ channel, BW534U87 produced a concentration- and voltage-dependent inhibition of Na+ currents with a half-maximal inhibitory concentration of 10 micronM at a Vh of -60 mV. Use-dependent inhibition was evident at high-frequencies (20x20 ms pulse train at 10 Hz). 4 In conclusion, BW534U87 blocks hippocampal epileptiform activity by a dual mechanism. The first action is similar to that produced by EHNA and is dependent on endogenous adenosine probably by inhibition of adenosine deaminase. Secondly, BW534U87 directly inhibits voltage-gated Na+ channels in a voltage- and frequency-dependent manner. Both actions of BW534U87 are activity-dependent and may synergistically contribute to its overall anticonvulsant effects in animal models of epilepsy.  (+info)

A normal level of adenosine deaminase activity in the red cell lysates of carriers and patients with severe combined immunodeficiency disease. (6/193)

The red cell lysates of two children with severe combined immunodeficiency disease (SCID) exhibited a virtually total absence of adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4) when standard volumes were assayed. Under these conditions the parents exhibited depressed specific activity except for one mother, whose lysate showed a normal value for activity. Upon storage of the lysate at 4 degrees, a significant amount of activity appeared in one of the SCID children, and the activity of the heterozygous carriers was stimulated. With the use of a sensitive spectrophotometric assay based on conversion of inosine to uric acid, it was shown that the specific enzymatic activity in each of the SCID patients increased progressively as the volume of lysate assayed was lowered. With the smallest amount of lysate this specific activity was in the normal range. Similarly, the specific activity of each of the parents' lysates increased to the level of normal (or, in one case, about twice normal) as smaller volumes were assayed. The activity in the SCID patient was inhibitable by 2-fluoroadenosine and N6-methyladenosine, known competitive inhibitors of human red cell adenosine deaminase. The lysate from the SCID patient was also shown to inhibit adenosine deaminase partially purified from a normal individual. The results are interpreted in terms of a genetically programmed production of an adenosine deaminase inhibitor in at least one variant of the severe combined immunodeficiency disease.  (+info)

Age-related changes in A(1)-adenosine receptor-mediated bradycardia. (7/193)

The impact of age on functional sensitivity to A(1)-adenosine receptor activation was studied in Langendorff-perfused hearts from young (1-2 mo) and old (12-18 mo) male Wistar rats. Adenosine mediated bradycardia in young and old hearts, with sensitivity enhanced approximately 10-fold in old [negative logarithm of EC(50) (pEC(50)) = 4.56 +/- 0.11] versus young hearts (pEC(50) = 3.70 +/- 0. 09). Alternatively, the nonmetabolized A(1) agonists N(6)-cyclohexyladenosine and (R)-N(6)-phenylisopropyladenosine were equipotent in young (pEC(50) = 7.43 +/- 0.12 and 6.61 +/- 0.19, respectively) and old hearts (pEC(50) = 7.07 +/- 0.10 and 6.80 +/- 0. 11, respectively), suggesting a role for uptake and/or catabolism in age-related changes in adenosine sensitivity. In support of this suggestion, [(3)H]-adenosine uptake was approximately twofold greater in young than in old hearts (from 3-100 microM adenosine). However, although inhibition of adenosine deaminase and adenosine transport with 10 microM erythro-9-(2-hydroxy-3-nonyl)adenine hydrochloride and 10 microM S-(4-nitrobenzyl)-6-thioinosine increased adenosine sensitivity three- to fourfold, it failed to abolish the sensitivity difference in old (pEC(50) = 4.95 +/- 0.08) versus young (pEC(50) = 4.29 +/- 0.13) hearts. Data indicate that 1) age increases functional A(1) receptor sensitivity to adenosine without altering the sensitivity of the A(1) receptor itself, and 2) age impairs adenosine transport and/or catabolism, but this does not explain differing functional sensitivity to adenosine. This increased functional sensitivity to adenosine may have physiological significance in the older heart.  (+info)

Adenosine-mediated killing of cultured epithelial cancer cells. (8/193)

Because micromolar concentrations of adenosine (Ado) have been documented recently in the interstitial fluid of carcinomas growing in animals, we examined the effects of low concentrations of Ado on the growth of cultured human carcinoma cells. Ado alone had little effect upon cell growth. In the presence of one of a number of Ado deaminase (ADA) inhibitors, Ado led to significant growth inhibition of all cell lines tested. Similar effects were found when ATP, ADP, or AMP was substituted for Ado. Surprisingly, the ADA inhibitor coformycin (CF) had a much greater potentiating effect than did 2'-deoxycoformycin (DCF), although DCF is a more potent ADA inhibitor. The growth inhibition of the Ado/CF combination was not abrogated by pyrimidines or caffeine, a nonspecific Ado receptor blocker. Toxicity was prevented by the addition of the Ado transport inhibitor dipyridamole or the Ado kinase inhibitor 5'-amino 5'-deoxyadenosine. S-Adenosylhomocysteine hydrolase is not involved because neither homocysteine thiolactone nor an S-adenosylhomocysteine hydrolase inhibitor (adenosine dialdehyde) potentiated toxicity of the Ado/CF combination. Unexpectedly, substitution of 2'-deoxyadenosine (the toxic moiety in congenital ADA deficiency) for Ado, did not lead to equivalent toxicity. The Ado/CF combination inhibited DNA synthesis and brought about morphological changes consistent with apoptosis. Together, these findings indicate that the Ado-mediated killing proceeds via an intracellular route that requires the action of Ado kinase. The enhanced cofactor activity of CF may be attributable to its being a more potent inhibitor of AMP deaminase than is DCF.  (+info)

We examined the in vivo effects of a potent inhibitor of ADA, 2-deoxycoformycin, which was used to treat a patient with refractory acute leukemia. Unexpectedly, within 7 days of starting treatment, the leukemic phenotype underwent complete conversion from T lymphoblastic to promyelocytic, with kinetics that suggested a precursor-product relationship between the two cell populations. Pretreatment of T lymphoblasts and posttreatment of promyelocytes had the same abnormal karyotype. Upon culture in vitro, the former transformed spontaneously over several weeks into mature myeloid cells. We ...
Iodotubercidin is an adenosine kinase inhibitor that through its ability to increase levels of endogenous adenosine can enhance adenosines receptor-mediated effects. We investigated whether iodotubercidin can inhibit [3H]adenosine accumulation by inhibiting transport processes in addition to inhibition of intracellular trapping of labeled adenine nucleotides. Under conditions in which extensive metabolism of intracellular adenosine was present, [3H]adenosine accumulation by DDT1 MF-2 cells was almost completely inhibited by iodotubercidin and the adenosine deaminase inhibitor erythro-9-(2-hydroxy-3-nonyl)-adenine or by the nucleoside transport inhibitor nitrobenzylthioinosine. By using similar conditions, [3H]adenosine accumulation was significantly greater in Na+ buffer than in buffer containing N-methyl-D-glucamine in place of Na+; however, this effect may be explained by an observed 40% inhibition of adenosine kinase activity by N-methyl-D-glucamine. By using uptake intervals of 14 sec to ...
Adenosine deaminase (ADA) is an enzyme involved in purine metabolism. It is needed for the breakdown of adenosine from food and for the turnover of nucleic acids in tissues. Present in virtually all mammalian cells, its primary function in humans is the development and maintenance of the immune system. Adenosine deaminase is considered one of the key enzymes of purine metabolism. Adenosine deaminase in humans is involved in the development and maintenance of the immune system. However, Adenosine deaminase association has also been observed with epithelial cell differentiation, neurotransmission, and gestation maintenance. It has also been proposed that Adenosine deaminase, in addition to adenosine breakdown, stimulates release of excitatory amino acids and is necessary to the coupling of A1 adenosine receptors and heterotrimeric G proteins.. ...

Studies on the effect of genetic polymorphisms known to affect AMP deaminase (AMPD) activity on progress of heart disease are conflicting: some highlights benefit of decreased AMPD activity in heart failure and ischemic heart disease while the other failed to confirm it. Detailed studies to identify clinical scenario that benefits from decreased AMPD activity are thus needed. We evaluated cardiac effects of decreased AMPD activity during acute oxygen deprivation in clinical and experimental settings. Patients undergoing coronary artery bypass grafting with use of extracorporeal circulation (n=184) were clinically analyzed and genotyped for C34T mutation of AMPD1 that we previously found to decrease cardiac AMPD activity. The effect of new inhibitor of AMPD: 3-[2-(3-carboxy-4-bromo-5,6,7,8-tetrahydronaphthyl)ethyl]-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-ol (AMPDI) was tested in apoA/LDLr knockout mouse exposed for 5 min to 5% oxygen in breathing air.

Hereditary deficiency of the enzyme adenosie deaminase (adenosine aminohydrolase, EC 3.5.4.4) results in an immunodeficiency syndrome characterized by a marked reduction in circulating lymphocytes. We have administered 2-deoxycoformycin, a potent inhibitor of adenosine deaminase, to a patient with a lymphoproliferative malignancy. The clinical consequences of pharmacologic inhibition of adenosine deaminase activity included an abrupt decrease in the lymphocyte count, abnormalities of renal and hepatic function, and hemolytic anemia. The plasma concentrations of adenosine and deoxyadenosine rose to peak values of 13 microM and 5 microM, respectively, and erythrocyte dATP levels increased to 110 pmol/10(6) cells over 9 days. There was a corresponding decrease in erythrocyte ATP levels from 128 to , 6 pmol/10(6) cells. A similar profound reductin in ATP occurred in the erythrocytes of a second patient. The rapid and unexpected depletion of ATP associated with dATP accumulation may account, at ...
This study will evaluate a new method for delivering gene transfer therapy to patients with severe combined immunodeficiency disease (SCID) due to a defective adenosine deaminase (ADA) gene. This gene codes for the adenosine deaminase enzyme, which is essential for the proper growth and function of infection-fighting white blood cells called T and B lymphocytes. Patients who lack this enzyme are vulnerable to frequent and severe infections.. Some patients with this disease receive enzyme replacement therapy with weekly injections of the drug PEG-ADA (ADAGEN). This drug may increase the number of immune cells and reduce infections, but it is not a cure. Gene transfer therapy, in which a normal ADA gene is inserted into the patient s cells, attempts to correct the underlying cause of disease. This therapy has been tried in a small number of patients with varying degrees of success. In this study, the gene will be inserted into the patient s stem cells (cells produced by the bone marrow that mature ...

Adenosine deaminase deficiency (also called ADA deficiency or ADA-SCID) is an autosomal recessive metabolic disorder that causes immunodeficiency. It occurs in fewer than one in 100,000 live births worldwide. It accounts for about 15% of all cases of severe combined immunodeficiency (SCID). ADA deficiency may be present in infancy, childhood, adolescence, or adulthood. Age of onset and severity is related to some 29 known genotypes associated with the disorder. The main symptoms of ADA deficiency are pneumonia, chronic diarrhea, and widespread skin rashes. Affected children also grow much more slowly than healthy children and some have developmental delay. Most individuals with ADA deficiency are diagnosed with SCID in the first 6 months of life. The enzyme adenosine deaminase is encoded by a gene on chromosome 20. ADA deficiency is inherited in an autosomal recessive manner. This means the defective gene responsible for the disorder is located on an autosome (chromosome 20 is an autosome), and ...

OBJECTIVE: Adenosine deaminase (ADA) may be multifunctional, regulating adenosine levels and adenosine receptor (AR) agonism, and potentially modifying AR functionality. Herein we assess effects of ADA (and A(1)AR) deficiency on AR-mediated responses and ischaemic tolerance. METHODS: Normoxic function and responses to 20 or 25min ischaemia and 45min reperfusion were studied in isolated hearts from wild-type mice and from mice deficient in ADA and/or A(1)ARs. RESULTS: Neither ADA or A(1)AR deficiency significantly modified basal contractility, although ADA deficiency reduced resting heart rate (an effect abrogated by A(1)AR deficiency). Bradycardia and vasodilation in response to AR agonism (2-chloroadenosine) were unaltered by ADA deficiency, while A(1)AR deficiency eliminated the heart rate response. Adenosine efflux increased 10- to 20-fold with ADA deficiency (at the expense of inosine). Deletion of ADA improved outcome from 25min ischaemia, reducing ventricular diastolic pressure (by 45%; ...
TY - JOUR. T1 - Structural basis for the growth factor activity of human adenosine deaminase ADA2. AU - Zavialov, Anton V.. AU - Yu, Xiaodi. AU - Spillmann, Dorothe. AU - Lauvau, Grégoire. AU - Zavialo, Andrey V.. PY - 2010/4/16. Y1 - 2010/4/16. N2 - Two distinct adenosine deaminases, ADA1 and ADA2, are found in humans. ADA1 has an important role in lymphocyte function and inherited mutations in ADA1 result in severe combined immunodeficiency. The recently isolated ADA2 belongs to the novel family of adenosine deaminase growth factors (ADGFs), which play an important role in tissue development. The crystal structures of ADA2 and ADA2 bound to a transition state analogue presented here reveal the structural basis of the catalytic/signaling activity of ADGF/ADA2 proteins. In addition to the catalytic domain, the structures discovered two ADGF/ADA2-specific domains of novel folds that mediate the protein dimerization and binding to the cell surface receptors. This complex architecture is in sharp ...
This study will monitor the long-term effects of gene therapy in patients with severe combined immunodeficiency disease (SCID) due to a deficiency in an enzyme called adenosine deaminase (ADA). It will also follow the course of disease in children who are not receiving gene therapy, but may have received enzyme replacement therapy with the drug PEG-ADA.. ADA is essential for the growth and proper functioning of infection-fighting white blood cells called T and B lymphocytes. Patients who lack this enzyme are, therefore, immune deficient and vulnerable to frequent infections. Injections of PEG-ADA may increase the number of immune cells and reduce infections, but this enzyme replacement therapy is not a definitive cure. In addition, patients may become resistant or allergic to the drug. Gene therapy, in which a normal ADA gene is inserted into the patients cells, attempts to correcting the underlying cause of disease.. Patients with SCID due to ADA deficiency may be eligible for this study. ...

Psoriasis is a human skin condition characterized by epidermal hyperproliferation and infiltration of multiple leukocyte populations. Finally using a secreted and transmembrane protein library we found out high affinity relationships between human being IGFL1 and mIGFL and the TMEM149 ectodomain. TMEM149 (renamed here as IGFLR1) is an uncharacterized gene with structural similarity to the tumor necrosis element receptor family. Our studies demonstrate that IGFLR1 is definitely indicated primarily on the surface of mouse T cells. The connection between mIGFL and IGFLR1 receptor suggests mIGFL may influence T cell biology within inflammatory pores and skin conditions. (11). For hydrodynamic tail vein injection-induced manifestation of mIGFL 8 Balb/c mice were placed under a warmth light for 5 min before the injection to dilate the tail veins. Mice were then restrained in an acrylic chamber to allow access to their tails and 50 μg of bare pRK5 or pRK5 with N-terminal FLAG-tagged mIGFL inside a ...

To confirm the clinical diagnosis of ADA deficiency, it is first necessary to assess the patients immune function.. The workup should start with a complete blood cell (CBC) count with differential to determine absolute lymphocyte count, as well to assess lymphoid subpopulations/markers (i.e., percentages and absolute counts of CD3+ T cells, CD4+ T cells, CD8+ T cells, CD19+ B cells, and natural killer (NK) cell markers (CD16 and CD56)). In all ADA SCID patients, T cells, B cells, and NK cells are severely affected (T-B-NK- phenotype).. Lymphopenia with an absolute lymphocyte count of less than 2500 cells/mL in an infant definitely requires further testing. Any infant with severe or opportunistic infection should have the full diagnostic assessment. On average, SCID patients have less than 1500 lymphocytes/mL.. Total serum immunoglobulin (Ig) levels of IgG, IgA, IgM, and IgE should be obtained. All immunoglobulin classes are usually decreased, but not always.. Evaluation of lymphocyte function ...

Diagnosis of tuberculosis from different body fluids remains challenging due to various limitations of the conventional and molecular methods. We studied the role of adenosine deaminase (ADA) assay to diagnose tubercular infection in cerebrospinal fluid, peritoneal fluid and pleural fluid. Fifty three patients with tubercular meningitis, peritonitis and pleuritis were enrolled in this study on the basis of clinical, radiological, cytological, biochemical and somewhere bacteriological evidences. Cases positive by AFB smear, culture or PCR were considered as confirmed TB and other as probable TB cases. Another 28 non-TB cases were included as control. In 53 suspected TB cases ADA was found positive in highest 42 (79.2%) cases, whereas smear and/ culture in 10 (18.7%) and PCR in 18 (33.9%) cases. ADA assay revealed 100% positivity in confirmed TB cases and 14.3% in non TB cases. The sensitivity and specificity of ADA was found 79% and 86% respectively when the cut off value was used ≥ 10 IU/L for CSF and

One particular kind of SCID, called adenosine deaminase deficiency (ADA)-SCID, is caused by lack of an enzyme (a protein in the body that helps break down other chemicals). Patients with ADA-SCID typically have very low T-cells, B-cells, and NK-cells because toxic byproducts build up as result of lack of the ADA enzyme. Patients with ADA-SCID present with similar infections as seen with the other forms of SCID.. ADA-SCID is the only type of SCID where patients can receive enzyme replacement. The enzyme has been made into a drug known as PEG-ADA (Adagen ®). At the present time, PEG-ADA comes from cows (bovine), although attempts are underway to make a recombinant form that does not come from animals. PEG-ADA is given by a needle into the muscle (intramuscularly). Patients / parents learn to inject it themselves. Usually it is given once per week, although dose changes (both in terms of total dose and the frequency with which PEG-ADA is administered) may need to occur based upon ADA levels that ...
