Abstract
Common variable immunodeficiency (CVID) is a primary immunodeficiency characterized by hypogammaglobulinaemia and recurrent infections. Although the underlying cause is unknown, B cells from most CVID patients fail to differentiate to memory or plasma cells. We investigated if increased apoptosis could influence the fate of B cells. For this purpose we activated purified B lymphocytes of CVID patients with a surrogate T-dependent (anti-CD40) or T-independent [cytosine-phosphate-guanosine oligodeoxynucleotides (CpG-ODN) or anti-immunoglobulin (Ig)M)] stimulus with or without interleukin (IL)-21. We found that CD27(+) B cells were more sensitive than CD27(-) B cells to spontaneous apoptosis and less sensitive to rescue from apoptosis. The addition of IL-21 down-modulated the protective effect of all the stimuli on CD27(-) B cells and the protective effect of CpG-ODN and anti-IgM on CD27(+) B cells. In contrast, IL-21 rescued unstimulated CD27(-) B cells and improved the rescue of anti-CD40-stimulated CD27(+) B cells. When we compared patients and controls, mainly CD27(+) B cells from MB0 patients were less sensitive to rescue from apoptosis than those from MB1 patients and controls after activation, irrespective of the IL-21 effect. Increased apoptosis during an immune response could result in lower levels of immunoglobulin production in these patients.

Abstract
A variety of strategies have been designed for sequence-based HLA typing (SBT) and for the isolation of new human leucocyte antigen (HLA) alleles, but unambiguous characterization of complete genomic sequences remains a challenge. We recently reported a simple method for the group-specific amplification (GSA) and sequencing of a full-length C*04 genomic sequence in isolation from the accompanying allele. Here we build on this strategy and present homologous methods that enable the isolation of HLA-C alleles belonging to another two allele groups. Using this approach, which can be applied to sequence-based typing in some clinical settings, we have successfully characterized three novel HLA-C alleles (C*04:128, C*07:01:01:02, and C*08:62).

Abstract
BACKGROUND Dermatophagoides pteronyssinus specific IgE (sIgE) measurement is a major diagnostic test for the detection of sensitization to that allergen. METHODS To investigate the effect of climate on the seasonal variations of D.pteronyssinus sIgE, we studied the tests performed in an insular population during a 10-year period. The association with meteorological factors was evaluated with multiple regression analyses. RESULTS Of 24,879 tests performed for D. pteronyssinus sIgE, 16,719 (67.2%) were D. pteronyssinus sIgE positive; 24.5% were tested for asthma and 46.07% for rhinitis. D. pteronyssinus sIgE levels showed a seasonal pattern with an annual peak in November. In the multivariate analyses solar radiation (r = -0.94) and relative humidity (r = 0.86) were independent factors associated with D. pteronyssinus sIgE levels. The resulting model could explain 93% (p < 0.001) of D. pteronyssinus sIgE variability. CONCLUSIONS Our population showed a seasonal pattern of D. pteronyssinus sIgE explained by relative humidity and solar radiation.

Abstract
The objective of this work was to study the role of mannose-binding lectin (MBL) and C-reactive protein (CRP) in pneumococcal pneumonia, to determine whether MBL acts as an acute-phase reactant and whether the severity of the disease correlates with MBL levels. The study comprised 100 patients with pneumococcal pneumonia. The pneumonia severity score was calculated and graded into a risk class of mortality (Fine scale). The MBL genotypes and the levels of MBL and CRP at the acute and recovery phases were determined. Fifty patients with the wild-type MBL genotype showed higher MBL levels in each phase (P < 0.001) and an increased risk to developing bacteraemia, odds ratio (OR) 2.74, 95% confidence interval (CI) 1.01-7.52) (P = 0.02), but this did not correlate with the pneumonia severity class. CRP levels in the acute phase, 79.53 mg/l [standard deviation (s.d.) 106.93], were higher in the subjects with positive blood cultures (P = 0.003), and remained higher [20.12 mg/l (s.d. 31.90)] in the group of patients with an underlying disease (P = 0.01). No correlation was observed between the levels of MBL and CRP in each phase, or with the pneumonia severity score. We cannot conclude that MBL acts uniformly as an acute-phase reactant in pneumococcal pneumonia. MBL levels do not correlate well with the severity of the pneumonia. The risk of developing bacteraemia could be enhanced in individuals with the wild-type MBL genotype.

Abstract
The aetiology of Behçet's disease (BD) is still unknown, but genetic and environmental factors are involved. HLA-B*51 is considered a susceptibility marker and some MICA alleles have also been associated. Cytotoxic T lymphocytes have been suggested as responsible for BD lesions by engaging MICA through NKG2D surface molecules. In the present study, HLA-B and MICA alleles were typed by polymerase chain reaction using sequence-specific primers, in 165 healthy Spanish controls and 42 BD patients. In the healthy group, MICA*008 (28.48%), MICA*004 (17.58%), MICA*002 (14.24%) and MICA*009 (9.39%) were the predominant alleles and the most common haplotype was MICA*004-B*44 (12.12%). MICA*001 (5.15%), MICA*004, MICA*011 (4.54%) and MICA*018 (5.15%) were more frequent, and MICA*010 (1.81%) and MICA*008 were less prevalent than in other Caucasoid populations. Similar results have been reported in North African individuals and this could support the hypothesis of a common ancestral origin of both populations. The frequencies of MICA*009 and MICA*019 were significantly increased in our BD patients in comparison with controls: 22.62% versus 9.39% and 10.71% versus 1.81% respectively. The increase of MICA*019 had not been described in other BD cohorts, and it corroborates the genetic heterogeneity at MICA locus in BD patients. High-affinity MICA alleles for NKG2D were more frequent in controls than in patients. Moreover, high-affinity alleles were not found in homozygous BD patients. These results argue against the hypothesis of an autoaggressive response in BD patients through MICA-NKG2D interactions.

Abstract
Common variable immunodeficiency disease (CVID) is a heterogeneous syndrome characterized by low immunoglobulin serum levels and recurrent bacterial infections. Several studies suggest that CVID patients have a polarized immune response towards a T helper type 1 phenotype (TH1). However, the factors causing the TH1 polarization remain to be determined in this disease. In the present study, serum interleukin (IL)-12, interferon (IFN)-gamma levels and the IL-12p40 and IFN-gamma gene were studied in CVID patients. Furthermore, we evaluate dendritic cells (DCs) compartment, myeloid dendritic cells (mDCs) and plasmocytoid dendritic cells (pDCs), which help to differentiate naive T cells preferentially into TH1 and TH2, respectively. The serum IL-12p40 subunit levels were increased significantly in CVID patients compared to healthy controls. We examined whether these elevated serum IL-12p40 levels are associated with IFN-gamma or IL-12p40 gene polymorphisms, or with new mutations in the IL-12p40 promoter gene. In our hands, no new mutations were found and gene polymorphisms frequencies in CVID patients were similar to the control population. In conclusion, the elevated serum levels of IL-12p40 found in our CVID patients were not related to these genetic variations. The DC compartment analysis did not show an imbalance between pDCs and mDCs, but revealed the presence of low numbers and percentage of both DC populations in CVID.

Abstract
Common variable immunodeficiency (CVID) is a heterogeneous syndrome characterized by hypogammaglobulinaemia and recurrent infections. Although early works pointed to a primary B-lymphocyte defect as a cause of the disease, a failure in T-lymphocyte cooperation has also been suggested. T cells exert their costimulatory function through either membrane costimulatory molecules or secreted cytokines, both having an influence in the development of the humoral response. The aim of our study was to evaluate whether an abnormal expression and induction of costimulatory molecules or alterations in the production of cytokines by T cells cause deficient T/B cooperation in CVID patients. We studied the expression and upregulation of costimulatory molecules (CD28, CD40L/CD154 and CTLA-4/CD152) and production of cytokines (IL-2, IL-4, IL-6, IL-10, IFN-gamma and TNF-alpha) in purified T lymphocytes from CVID patients stimulated with optimal doses of anti-CD3 or suboptimal doses of anti-CD3 and anti-CD28. Stimulated T cells from CVID patients expressed normal levels of CD28, CD40L/CD154 and CTLA-4/CD152 when compared with controls. Except for higher production of IL-4 after stimulation with anti-CD3, T cells of CVID patients produced similar amounts of cytokines compared with controls. An imbalance between costimulatory molecules expression (CD28, CD40L/CD154 and CTLA-4/CD152) and cytokine production by T cells does not explain a deficient cooperation between T and B cells in this group of CVID patients.

Abstract
The aim of the study was to determine possible factors related to the risk of developing recurrent bacterial respiratory tract infections in HIV-1-infected patients, regardless of the degree of immune cellular impairment. Thirty-three HIV-1 seropositive patients with previous repetitive bacterial respiratory tract infections (case group), 33 HIV-1 seropositive controls (matched by CD4-cell counts) without these antecedents and 27 healthy controls were studied before and after administration of pneumococcal and Haemophilus influenzae type b vaccines. Clinical or toxicological variables, cutaneous tests, complement factors, beta2-microglobulin, serum IgM, IgA, IgG and subclasses, specific antibodies (IgG, IgG2, IgA) against pneumococcal vaccine and polyribosylribitol phosphate (PRP), their avidity, opsonophagocytosis and IgG(2)m and Fc(gamma)RIIa allotypes were determined. A history of drug abuse (P = 0.001), less likelihood of receiving high activity antiretroviral treatment high activity antiretroviral treatment (HAART) (P = 0.01), higher levels of HIV-1 viral load (P < 0.05), serum IgG (P < 0.01) and beta2-microglobulin (P < 0.01) were observed in the case group. Also, a lower increase in specific antibodies to pneumococcal vaccine and PRP was demonstrated in the cases in comparison with the two control groups. No differences were observed in the avidity of antibodies, opsonophagocytic capacity or IgG(2)m and Fc(gamma)RIIa allotypes between the three groups. These data indicate that vaccination strategies against encapsulated bacteria can be unsuccessful in the HIV-1-infected patients presenting repetitive bacterial respiratory tract infections if behavioural aspects or measures to improve adherence to HAART therapies are not considered.

Abstract
'Chueta' was the name given to the Catholic descendants of Jewish victims of the last Spanish Inquisition process in Majorca Island in the western Mediterranean. We have studied the allele distribution of HLA-A, -B, -Cw, -DRB1 and -DQB1 loci of 103 random, healthy, unrelated individuals belonging to the ancient Majorcan Jewish community, known locally as Chuetas, and 589 individuals from the Balearic population selected because of their typical Balearic - Majorca, Minorca or Ibiza - lineages and according to their ancestor's place of birth. Our aim was to establish the genetic relationship between Majorcan Chuetas, and Balearic and other Jewish and Mediterranean populations. Our results have shown that, to a remarkable extent, they have retained their biological identity, with a unique pattern, in terms of gene and haplotype frequencies, separate from the other populations of Majorca. The Chuetas were found to be more related to Moroccan and Libyan Jews than other Majorcans. Characteristic Jewish haplotypes, A26-B38-DRB1*13, A24-B38-DRB1*11, A1-B52-DRB1*15/16, were found in our study. Some peculiarities were observed in the distribution of common haplotypes among the three main Balearic Islands. The Ibizan population was genetically different from the other Balearic populations, with a high frequency of some haplotypes, for example, A29-Cw*16-B44-DRB1*07-DQB1*03; A1-Cw*07-B8-DRB1*03-DQB1*02. We also found a new haplotype, A25-Cw*12-B39-DRB1*11-DQB1*03(3.5%), in Ibizans and a more limited variability in the HLA alleles that were expressed, perhaps because of genetic isolation. The genetic diversity of the populations from Majorca and Minorca were similar and more related to the mainland Spanish population.

Abstract
In this paper we describe the clinical and molecular features of a new case (GOR) of homozygous human TAP2 deficiency, analysing the phenotype and function of NK cells. The patient presented from infancy with recurrent sinopulmonary infections; a selective IgG2 deficiency, negative antibody response to polysaccharide vaccination and low level of cell surface expression of HLA class I antigens were found. The sequence of TAP2 gene identified a single mutation, a C to T substitution changing the CGA arg codon at amino acid 220 into TGA stop codon in exon 3. By using MoAbs for KIRs, CD94, CD94/NKG2A and ILT2 we observed, in agreement with others, that the latter two receptors were overexpressed on TAP2-deficient NK cells. The inhibitory CD94/NKG2A and triggering CD94/NKG2C NK receptors, specific for HLA-E, appeared to be functional in a limited number of NK clones that could be expanded in vitro. Expression of HLA-E was virtually undetectable in GOR B-LCL and very faint in PBMC, further supporting that interactions of class I leader sequence nonamers with HLA-E in the ER depend on a functional TAP complex.

Abstract
The hyper-IgE syndrome (HIES) is a rare primary immunodeficiency characterized by recurrent skin abscesses, pneumonia, and highly elevated levels of serum IgE. HIES is now recognized as a multisystem disorder, with nonimmunologic abnormalities of the dentition, bones, and connective tissue. HIES can be transmitted as an autosomal dominant trait with variable expressivity. Nineteen kindreds with multiple cases of HIES were scored for clinical and laboratory findings and were genotyped with polymorphic markers in a candidate region on human chromosome 4. Linkage analysis showed a maximum two-point LOD score of 3.61 at recombination fraction of 0 with marker D4S428. Multipoint analysis and simulation testing confirmed that the proximal 4q region contains a disease locus for HIES.

Abstract
Apoptosis is now recognized as a central process of development and disease, and it has been proposed as one of the mechanisms that may account for the lymphopenia seen in some diseases. In this study we measured spontaneous apoptosis and CD95 expression on different cell subpopulations from CVID patients, using flow cytometric techniques. We divided our patients into two groups according to their CD4+ and CD4+CD45RA+ cell counts. Our results clearly show increased spontaneous apoptosis and CD95 expression on the CD4+ and CD4+CD45RA+ subsets from lymphopenic CVID patients compared with normal subjects and disease controls. Interestingly, our lymphopenic CVID patients presented a profound reduction in absolute counts, mainly affecting the CD4+CD45RA+ subpopulation. We also found a statistically significant direct correlation between absolute numbers of CD4+CD45RA+ T cells and spontaneous apoptosis on the same subset in CVID patients, but attempts to induce CD95-mediated apoptosis were unsuccessful despite increased CD95 expression on CD4+ T cells. These findings suggest that apoptosis could be one of the mechanisms implicated in the significant lymphopenia present in these patients.

Abstract
Deficiency of the seventh component of complement (C7D) is frequently associated with recurrent neisserial infections. We report in the present study the genetic basis for C7D in a Spanish family. We used exon-specific polymerase chain reaction (PCR)/single-strand conformation polymorphism (SSCP) analysis as a screening step for mutations, followed by direct sequencing of the target exon. The mutation in the proband was a homozygous G-to-T transversion at nucleotide 1957, the first nucleotide of the codon GAG for Glu-631, leading to a stop codon TAG (E631X). Our result provides further evidence that the molecular pathogenesis of C7D is heterogeneous.

Abstract
Gammadelta T lymphocytes respond to different bacterial antigens and transformed cells. The antigenic molecules responsible for this activity have been studied extensively in antigenic preparations from Mycobacterium. We describe here the in vitro effect of Pseudomonas aeruginosa on gammadelta T lymphocytes and the properties of the implicated compounds. We found a preferential gammadelta T-cell expansion when we used heat-treated P. aeruginosa preparations and a dose-dependent inhibition of proliferation of peripheral blood mononuclear cells (PBMC) when non-heat-treated antigens were studied. This expansion corresponded to a Vgamma9-positive subpopulation. In contrast to alphabeta T lymphocytes, the highest stimulatory activity was restricted to very small cytosolic compounds. This activity was protease resistant and phosphatase sensitive and always dependent on interleukin (IL)-2 or alphabeta T-cell activation. We concluded that the antigenic molecules from P. aeruginosa that activated gammadelta T lymphocytes were small, non-peptidic, phosphorylated compounds, similar to those previously described from Mycobacterium.

Abstract
BACKGROUND Cryopreservation of hematopoietic cells with the rate-controlled method is used in the majority of centers. In recent years, there has been a trend toward the simplification of the process. STUDY DESIGN AND METHODS A simplified method for cryopreservation was developed with 5-percent dimethyl sulfoxide (DMSO) as the sole cryoprotectant without rate-controlled freezing. Experiments were done with progressive concentrations of DMSO, ranging from 0 to 10 percent. With DMSO concentrations from 5- to 10-percent, the best recovery and viability for hematopoietic progenitor cells were observed. Hematopoietic progenitor cells with plasma and 5-percent DMSO were frozen and stored in a -80 degrees C mechanical freezer. Ten patients with solid and hematologic malignancies underwent transplantation with autologous hematopoietic progenitor cells. RESULTS The median number of transfused mononuclear cells and CD34+ cells was 3.70 (3.1-8.2) x 10(8) per kg and 1.70 (0.8-6.5) x 10(6) per kg, respectively. The median number of transfused colony-forming units-granulocyte-macrophage was 12.45 (3.4-55.3) x 10(4) per kg. All patients showed rapid and sustained engraftment. The mean times to reach a neutrophil count of 0.5 x 10(9) per L and a platelet count of 50 x 10(9) per L were 11.50 +/- 1.70 and 13.90 +/- 3.98 days, respectively. All patients are alive and without transfusion requirements in complete remission 2 to 8 months after transplantation. CONCLUSION This simplified cryopreservation technique will be useful for institutions without rate-controlled freezing facilities. Moreover, this method diminishes the amount of DMSO infused to patients, as well as its toxicity.

Abstract
The failure of B cells from CVI patients to secrete normal amounts of antibodies has been attributed either to an intrinsic B cell defect or to a lack of cooperation from T cells. In an attempt to improve the definition of the origin of this defect in one of the main cellular compartments, we studied the ability of helper CD4 cells and their CD4 CD45RO subpopulation from CVI patients to secrete interleukins (IL-2 and IL-4) in response to mitogen stimulation. We found that CD4 and CD4 CD45RO cells from some patients secrete abnormal amounts of interleukins (in general low levels of IL-2 and high levels of IL-4) upon stimulation with pokeweed mitogen (PWM). These irregularities may contribute to the defective differentiation of B cells in these patients.

Abstract
A simplified method for cryopreservation was developed with 10% dimethylsulfoxide (DMSO) as the sole cryoprotectant without rate-controlled freezing. This method produced high recovery rate for mononucleated cells (87%) and elevated trypan blue viability (90%). Autologous peripheral blood stem cells (PBSCs) and bone marrow cells with plasma and 10% DMSO were frozen and stored in a -80 degrees C mechanical freezer. Eleven patients with solid and hematological malignancies were transplanted with autologous bone marrow or PBSCs. The median number of infused mononuclear cells (MNC) and CD34+ cells were 3.63 x 10(8)/Kg and 4.80 x 10(6)/Kg, respectively. The median number of infused post-thawing CFU-GM was 20 x 10(4)/Kg. All patients showed a rapid and sustained engraftment. The mean times to reach a neutrophil count of 0.5 x 10(9)/L and a platelet count of 50 x 10(9)/L were 11 and 13 days, respectively. All patients are alive and 10 in unmaintained complete remission for 3-9 months after transplantation. These results show the efficacy of this simplified cryopreservation technique that will be useful for institutions without rate-controlled freezing facilities.

Abstract
We report here an uncommon case of neonatal acute leukaemia that presented concomitant with serological evidence of rubella infection. The clinical course was aggressive and the patient died 5 days after diagnosis from septicaemia. Leukaemic blasts had a mixed lineage immunophenotype co-expressing a constellation of B-lymphoid (CD19, cytCD22, TdT) and myeloid (CD13, CD33, CD14, anti-MPO) markers, as well as multiple adhesion molecules and markers associated with early lympho-myeloid progenitor cells (CD34, CD7, HLA-DR). A previously unrecorded discordant expression of different CD10 and CD34 epitopes was identified using different monoclonal antibodies. The karyotype was 46,XX t(4;11)(q21;q23) and molecular analysis confirmed rearrangement of the trithorax-related oncogene HRX at 11q23. There was a clonal biallelic rearrangement of the immunoglobulin heavy-chain gene. The features of this rare case have implications for possible aetiological events leading to leukaemia.

Abstract
Thirty-one children aged five to 14 years with severe vernal keratoconjunctivitis (VKC) were enrolled in a double-masked study evaluating the efficacy of three ophthalmic preparations: cromolyn sodium (Opticrom) 2%, artificial tears and fluorometholone 0.1% (FML). These drugs were coded respectively as A, B, C, and dispensed in similar bottles. Both eyes were treated, and drug assignment was made at random. Objective assessment of the disease activity was done under slit lamp by two ophthalmologists according to a five-point scale. The results were tabulated and the chi-square test performed. Decoding of the drugs was done only after completion of the statistical analysis. FML was found effective with a statistically significant difference from the other two drugs, both after the first week on the initially assigned treatment (p = 0.05) and on completion of the treatment period according to protocol (p = 0.005). Although several patients improved under cromolyn sodium, there was no statistically significant difference between cromolyn sodium 2% and artificial tears. All the preparations were well tolerated. One patient developed bilateral allergic blepharitis when treated with FML during the study. Another patient who responded well to FML developed posterior subcapsular cataract while continuing treatment with corticosteroids a few months after completion of the study.

Abstract
There is evidence of the central regulation of intraocular pressure, and it has been suggested that vagal tone might be increased in glaucoma simplex. The nasal cycle, the simultaneous congestion-decongestion response in the nasal cavities, reflects the dynamic lateralisation of the autonomic nervous system. Since this lateralisation presents with sympathetic activity induced by left brain hemisphere stimulation and parasympathetic activity induced by right hemisphere stimulation, it was subsequently demonstrated that forced unilateral nostril breathing induces selective contralateral hemispheric stimulation as measured by relative increases in the electroencephalographic amplitude in the contralateral hemisphere as well as alternating lateralisation of plasma catecholamines. Using this functional vagotomy, we report that left hemispheric stimulation by 20 minutes of forced unilateral right nostril breathing led to a significant bilateral decrease of 4.6 mmHg (25%) in intraocular pressure in 46 patients with open and closed angle glaucoma. However, it significantly increased the IOP in three patients with neovascular, one with juvenile onset, and one with closed angle glaucoma.

Abstract
Patients receiving antimalarial therapy, specifically hydroxychloroquine, for different periods were evaluated using contrast sensitivity test (CST) and results were compared with those of electro-retinography (EOG), and pattern visual evoked potential (PVEP), and a matching age control group. The results indicated CST to be most sensitive of the evaluated techniques particularly in patients under 40 years old. In 44.4% of the cases CST revealed macular dysfunction of which the other two methods of examination were not capable. Our findings suggest the CST is a reliable and practical method which could be used as an additional screening test for chloroquine maculopathy.

Since this lateralization presents with sympathetic activity induced by left brain hemisphere stimulation and parasympathetic activity induced by right hemisphere stimulation, forced unilateral nostril breathing (FUNB) has recently been demonstrated to induce selective contralateral hemispheric stimulation as measured by relative increases in EEG amplitude in the contralateral hemisphere as well as alternating lateralization of plasma catecholamines. Using this functional vagotomy/sympathectomy, we report the novel finding that right hemispheric activation via left FUNB increases intraocular pressure (IOP) by an average of 4.5%, whereas left hemispheric stimulation via right FUNB leads to a significant (25%) decrease in IOP.

Abstract
A 22-year-old woman presenting with recurrent transient episodes of vertebro-basilar artery syndrome and blurred vision was initially diagnosed as suffering from a collagen disease affecting the retina and CNS. Treatment with systemic steroids induced an apparent remission. However, a rapid deterioration of her condition prompted a reevaluation of the diagnosis and treatment. Ophthalmoscopic examination disclosed numerous ischemic foci in both eyes, scattered superficial hemorrhages, and neovascular tufts on the optic nerves. The possibility that both the cerebral and ocular phenomena were the results of systemic showering of emboli was raised. Careful two-dimensional echo cardiography revealed a mitral mass compatible with myxoma of the left atrium. The difficult differential diagnosis of combined encephalopathy and retinopathy is discussed.

Abstract
Thirty patients suffering from severe sight-threatening bilateral chronic endogenous uveitis were treated with initial dosages of 10 mg/kg/d of CsA. After 1 month of therapy, all patients but one demonstrated a rapid decrease of the intraocular inflammatory processes along with an arrest of the deterioration of vision. After 1 year (or more) of treatment, most patients still show the same visual acuity achieved after 1 month. During the 3-year span of this study, attempts at tapering off the CsA dosage to less than 5 mg/kg/d induced a temporary flare-up in 20 of the 24 patients followed without interruption for more than 6 months. Nonetheless, control of the intraocular inflammation was finally achieved by 5 mg CsA/kg/d or less in 14 of the 25 patients. In six of these 14 patients the CsA dosage was further tapered to total discontinuation. Two of the six patients showed a rapid reactivation of the intraocular inflammatory processes with a profound decrease in vision within 1 and 3 weeks, respectively. In four patients, control of the intraocular inflammation and preservation of good visual acuity have been observed for a period of up to 18 months.

Abstract
Twenty-one children (4 to 12 years old) with severe vernal keratoconjunctivitis refractive to treatment with corticosteroid eyedrops and/or 2% disodium cromoglycate (Optic-rom, Fisons) were treated with CsA 2% eyedrops in oil solution. Eighteen patients (86%) experienced a rapid relief of their subjective symptoms three to four days after initiation of treatment. This was accompanied by objective improvement of ocular manifestations and visual acuity within a week. Sixteen of the children (76%) remained controlled during the 6-week period of treatment. However, only five patients (24%) did not need any additional therapy 2 months after discontinuation of the CsA eyedrops. These findings can be interpreted as an indication for the possible involvement of interleukin secretion in the clinical manifestations of vernal keratoconjunctivitis. Alternatively, the beneficial effects of CsA in this disease may be due to a direct effect on the mast cells preventing the release of their mediators.

Abstract
We report here the first paediatric immunodeficiency acquired syndrome (AIDS) in Spain, acquired by vertical-transmission and a second infant case with the same transmission and classified as AIDS related complex. We also mention the incidence and characteristics, of the neonatal population born in the last eighteen months to HIV positive mothers in our geographic area. The AIDS patients, was a female drug addicted parents born to who died at 22 month. Her parents are HIV positive and have ARC. The second patient was a boy, born to a sexual HIV positive partner of a member of a high risk group who died pat 17 month. Review of the literature until September 1986, revealed 369 AIDS paediatric patients, the number is lower 265 (7 Spanish), if only vertical transmitted AIDS is considered. For this reason, we considered pertinent to provide some information about clinical manifestations and laboratory, radiologic and necropsy findings in our patients.

Abstract
A fetal lactate dehydrogenase (LDH) isoenzyme pattern, with relative deficiency of LDH1, was found in enriched T cell preparations from patients with late onset and X-linked hypogammaglobulinaemia. This provides further evidence that such T cells are 'immature'.

Abstract
Lymphocytes from patients with primary immunodeficiency were tested histochemically for ecto 5'-nucleotidase (5'N) and alpha-naphthyl (non-specific) esterase. More than half the patients with 'common variable' hypogammaglobulinaemia, all those with X-linked hypogammaglobulinaemia and some of those with selective IgA deficiency had a very low percentage of lymphocytes staining for 5'N as compared to controls. A lack of B cells probably explains the finding in X-linked hypogammaglobulinaemia, but does not fully explain the results in the other groups. Most patients with 'common variable' hypogammaglobulinaemia had a very low percentage of lymphocytes with granular staining for alpha-naphthyl (non-specific) esterase in contrast to normal numbers in those with X-linked hypogammaglobulinaemia and most of those with selective IgA deficiency. Granules containing non-specific esterase are characteristically found in 'mature' T lymphocytes. The enzyme abnormalities in the T and B cells of 'common variable' hypogammaglobulinaemic patients could be explained by 'immature' cell types.
