17 Lee et al.18 assessed

whether there was any benefit from adding an anticholinergic agent in men with BOO and DO. Of 144 patients, 76 (53%) were diagnosed as having BOO and 68 (47%) BOO plus DO. In men with BOO plus DO, only 35% reported improvement in symptoms at the end of the initial 3-month treatment with doxazosin alone. The remaining 65% patients had no improvement, and were given tolterodine IR (2 mg twice daily) additionally. Seventy-three percent of patients assigned to combination therapy reported significant symptomatic improvement at the end of treatment. These results suggest that alpha-blocker monotherapy Linsitinib research buy has limited success in the treatment of OAB symptoms and that combination treatment with an anticholinergic is clinically effective when alpha-blocker therapy fails to resolve the symptoms IWR-1 nmr of OAB. Any therapy that targets only the prostate has limited therapeutic effects on OAB symptoms. Saito et al.19 reported the therapeutic benefit

of combined anticholinergic and α1-adrenergic antagonist compared with α1-adrenergic antagonist alone. They assessed the efficacy of the combination of propiverine (20 mg once daily) and tamsulosin (0.2 mg once daily) versus tamsulosin alone (0.2 mg once daily) in 134 BPH patients in a randomized, single-blind, multicenter trial for 4 weeks. Patients treated with combination therapy had a more favorable improvement in aspects of daytime frequency, urinary incontinence episodes, urgency and nocturia. The residual urine volume remained unchanged in both groups, while AUR occurred in only one patient (1.5%) in the combination group. The study concluded that combination therapy was promising for BPH patients. Lee et

al.20 published a prospective, randomized, double-blind, multicenter study that compared the efficacy and safety of combination therapy of propiverine and Sclareol doxazosin in patients with OAB syndrome and urodynamically proven BOO. Two hundred and eleven patients were randomized (1:2) to a doxazosin (4 mg once daily) only group or propiverine hydrochloride (20 mg once daily) plus doxazosin group for 8 weeks of treatment. This dosage of 20 mg was relatively lower than the dosage in European countries. Both groups showed significant improvement in urinary frequency, maximum flow rate, mean micturition volume, and International Prostate Symptom Score (IPSS). However, compared with the doxazosin only group, patients treated with combination therapy experienced higher rates of improvement in urinary frequency (23.5% vs 14.3%), and average micturition volume (32.3% vs 19.2%). In addition, the combination treatment group had greater improvement in IPSS storage score (41.3% vs 32.6%) and urgency score (42.9% vs 28.0%), and combination treatment did not worsen voiding symptoms. Patient satisfaction rate with treatment was significantly higher in the combination therapy group. The overall rate of adverse events was higher in the combination treatment group (28.6% vs 13.9%).

2E and Supporting Information Fig. 1). To ensure that acid-stripping of passively bound IgE is not affecting the detection of IgE, we repeated the Nb infection with CD23−/− IgEki/ki. Again, WT mice express IgG1 (19.9%), whereas only little chimeric IgE can be detected in the mesenteric lymph nodes of CD23−/− IgEki/ki mice (2.76%). Similar low level IgE expression was

seen in spleen and bone marrow of IgEki/ki PD0325901 research buy mice. PCR reveals the presence of membrane IgE-IgG1 transcripts in spleen (Fig. 2G) without IgE+ cells (Fig. 2F). These findings suggest that IgE-membrane expressing B cells in mice are either rare or cannot be expressed in vivo, even in the IgE-IgG1 chimeric form. In the case of Nb infection, this is fundamentally different from IgG1+ B cells, which can readily be detected in Selleck CHIR-99021 lymph nodes of infested mice. In this context, Achatz-Straussberger et al. [31]. demonstrated that IgE-secreting B cells, from a different IgE-IgG1 chimeric knock-in mouse called KN1, do migrate more efficiently toward the chemokine CXCL12 into plasma cell niches in the bone marrow. However, in our model bone marrow is not populated more efficiently by IgE+ B cells after Nb infestation. The knock-in strategy allows the natural recombination and selection process for the generation of an antigen-specific polyclonal immunoglobulin response. Immunization with the model antigen TNP-OVA, adsorbed to the Th-2 response favoring

adjuvant alum, allowed the comparison of IgE and IgG1 production (Fig. 3A). IgEwt/wt mice produced very little TNP-OVA-specific IgE, but high titers of TNP-OVA-specific total IgG, including IgG1 (Fig. 3B). In contrast, we observed a strong increase of antigen-specific IgE titers in the IgEki mice compared with that of WT littermates, an 11-fold increase for IgEwt/ki and a 42-fold increase for IgEki/ki, respectively. IgG1 was not significantly reduced

in IgEwt/ki, but is absent in IgEki/ki mice (Fig. 3B). The genetic deficiency of IgG1 may account for the reduction of total IgG in IgEki/ki mice, despite the relative increase in IgG2a, IgG2b, and IgG3 levels (Fig. 3B). One further difference between WT and IgEki is a significant increase in antigen-specific IgM (data not shown). One possible explanation is that CD23-mediated uptake GNE-0877 of antigen and a novel mechanism of an antigen transporting capacity by B cells to dendritic cells enhance the specific antigen response, which leads to a stronger immunoglobulin response [30]. This hypothesis is supported by the observation that the changes in CD23−/− IgE knock-in mice for IgG3 and IgG2b are less distinct or absent, respectively (Fig. 3C). Taken together, the IgE knock-in strategy leads to complete lack of IgG1 in homozygous IgEki mice, reduction of IgG and a very strong specific IgE response in both IgE knock-in genotypes. It was recently suggested that basophils have a crucial role in IgG1-mediated anaphylaxis [9].

This measurement has been shown to be proportional to the BM exit rate. Indeed, newly developed BM leukocytes transit from the BM parenchyma through the endothelium and into the BM sinusoids where they are transiently retained until their release into the blood circulation. Results presented in Fig. 4B showed that the percentage BGJ398 molecular weight of sinusoidal Ly6C− monocytes was significantly decreased in the BM of S1pr5−/− or Ccr2−/− mice compared to the BM of WT mice. By contrast, the

percentage of sinusoidal Ly6C− monocytes was significantly increased in the BM of Cx3Cr1gfp/gfp mice compared to the BM of WT mice. These results support a role for S1PR5 in the migration of Ly6C− monocytes from the parenchyma to the sinusoidal compartment of the BM, a process essential for exit from the BM. This process could be negatively regulated by CX3CR1, perhaps as a result of adhesive properties of CX3CR1. Second, we compared the fate of monocytes of different genotypes adoptively transferred into recipient mice. We performed intravenous injection of a 1:1 mixture of WT (CD45.1) and S1pr5−/− or Cx3cr1gfp/gfp (CD45.2) BM cells into recipient WT (CD45.1 × CD45.2) mice. Sixteen hours after transfer, we measured the frequency of donor monocyte subsets in the blood and the GSK1120212 research buy BM of recipient mice. We calculated the ratio between WT and KO donors for each subset before transfer and 16 h after transfer in the blood

and the BM. Cx3cr1gfp/gfp Ly6C− monocytes were barely detectable in both BM and blood of recipient mice, confirming the important role of CX3CR1

in the survival of Ly6C− monocytes (Fig. 4C, left panel). By contrast, transferred S1pr5−/− Ly6C− monocytes were almost absent from the blood but were represented at similar frequency as WT Ly6C− monocytes in the BM of recipient mice (Fig. 4C, right panel). These data support a role for S1PR5 in the egress of Ly6C− monocytes rather than in their survival. Third, we compared the ex vivo viability of WT and S1pr5−/− Ly6C− monocytes in the blood and BM of WT S1pr5−/−chimeric mice using AnnexinV/7-AAD staining. In both compartments, the viability of S1pr5−/− Ly6C− monocytes was slightly lower than that of WT Ly6C− monocytes (Fig. 4D). Moreover, irrespective of the mouse genotype, the viability of Ly6C− monocytes was lower in the BM than in the blood. We also assessed viability of WT and S1pr5−/− Wilson disease protein Ly6C− monocytes sorted by flow cytometry and cultured in the presence or absence of M-CSF. After 24 h, the viability of WT and S1pr5−/− Ly6C− monocytes was similar in both culture conditions (Fig. 4E). Finally, we measured the expression of Bcl2, an important anti-apoptotic molecule that has been shown to be down regulated in Cx3cr1gfp/gfp Ly6C− monocytes and to regulate their survival. The expression of Bcl2 was similar in Ly6C− monocytes from WT and S1pr5−/− mice but it was reduced in Cx3cr1gfp/gfp Ly6C− monocytes (Fig. 4F), as previously reported [21].

We investigated the renoprotective effect of erlotinib, a tyrosine kinase inhibitor that can block EGFR activity, on cisplatin (CP)-induced AKI. Methods: CP nephrotoxicity (CP-N) was induced in 6-week-old male Sprague-Dawley (SD) rats (n = 28) by intraperitoneal injection of CP (7 mg/kg) on day 0. Groups of animals were given either erlotinib (CP+E, 20 mg/kg,

n = 14) or vehicle (CP+V, n = 14) daily by oral gavage from day −1 to day 3. Five SD rats were used as normal control (NC). All rats were sacrificed on day 4. In addition, www.selleckchem.com/products/mi-503.html we analized the effects of erlotinib on signaling pathways involved in CP-N by using human renal proximal tubular cells (HK-2). Results: Compared to the NC rats, the CP+V rats exhibited marked AKI characterized by deterioration of renal function, severe tubulointerstitial (TI) damage, and increase in renal cortical mRNA learn more expressions for proinflammatory cytokines, profibrogenic genes, and pro-heparin-binding EGF-like growth factor (pro-HB-EGF). Compared to vehicle, erlotinib treatment significantly prevented body weight loss and increased urine volume. Erlotinib significantly improved renal function (serum creatinine: 1.6 ± 0.3 vs. 0.8 ± 0.2 mg/dL, p < 0.01) and ameliorated TI injury (the number of casts/HPF: 2.0 ± 0.7 vs. 0.7 ± 0.1, p < 0.01). PCNA-positive cells and TUNEL-positive

apoptotic cells were significantly reduced by erlotinib. Furthermore, renal cortical mRNA for profibrogenic genes, including TGF-β, collagen type 1, and type 3, were significantly reduced in the CP+E rats compared to the CP+V rats. Similar result was obtained in renal cortical mRNA for Bax/Bcl-2 ratio. On the other hands, erlotinib did not affect ED1 positive macrophages infiltration and mRNA expressions for pro-HB-EGF those and proinflammatory cytokines. Additionally, we observed that erlotinib significantly reduced the phosphrylation of MEK1/2 and Akt, which were induced by CP in HK-2. Conclusion: Our study shows that erlotinib has a renoprotective effect in CP-induced AKI, that could be attributable to the degradation

of apoptosis and proliferation in tubular cells partly through the inhibition of activated MAPK and PI3K-Akt signaling pathways. These results strongly suggest that erlotinib is useful for preventing AKI in patients receiving CP chemotherapy.

Serum creatinine is a poor biomarker for detection of renal impairment in cirrhotic patients.

These transitional cells then differentiate into either MHC class I (MHCI)-specific CD8+ single positive (CD8 SP) or MHC class II (MHCII)-specific CD4+ single positive (CD4 SP) thymocytes (reviewed in 4). Several proteins have been implicated in the regulation of thymic development and positive selection (reviewed in 5–7). However, the process

of positive selection remains poorly understood. Cylidromatosis tumor suppressor (CYLD) is one of the proteins that have been implicated in the regulation of thymocyte selection. It is the product of a tumor suppressor gene (Cyld) that has been implicated in the development of a number of human malignancies (reviewed in 8). CYLD is a negative regulator of the NF-κB and MAPK pathways. CHIR-99021 concentration It was originally implicated in

thymocyte development by the demonstration selleck kinase inhibitor of impaired SP thymocyte development in mice bearing null alleles 9. In addition, CYLD has been implicated in the regulation of peripheral T-cell homeostasis and in NKT and regulatory T-cell development 10–12. Recent studies from our lab uncovered CYLD’s involvement in the regulation of thymocyte positive selection in an NF-κB essential modulator (NEMO)-dependent manner 13. More specifically, thymocytes carrying a homozygous deletion of Cyld exon 9 (CyldΔ9) that results in the truncation of the deubiquitinating domain were blocked at the double dull stage and exhibited an increased propensity to die by apoptosis 13. The defective selection of CYLD-deficient thymocytes was restored upon concomitant inactivation of NEMO. These findings established for the first time a definitive functional

association between CYLD and NEMO in vivo, which is essential for the optimal selection of thymocytes. However, since NEMO regulates NF-κB and JNK activities 14, 15, both of which have been implicated in the process of thymocyte deletion 16, 17, the exact mechanism that underlies the defective selection of CYLD-deficient thymocytes remains unclear. In order to investigate this process further, IκB-kinase 2 (IKK2), which is the principal mediator Aprepitant of canonical NF-κB activation, was concomitantly inactivated with CYLD in thymocytes in order to evaluate specifically the contribution of NF-κB in CYLD-mediated selection of thymocytes. Mice with a thymocyte-specific truncation of the catalytic domain of CYLD were generated by crossing Cyldflx9/flx9 mice to LckCre-transgenic mice as previously described 13. The LckCre-Cyldflx9/flx9 mice were crossed with mice carrying a conditionally targeted Ikk2 allele (Ikk2flx/flx). More specifically, in Ikk2flx/flx mice, a premature stop codon can be conditionally introduced in the Ikk2 open-reading frame by Cre-mediated deletion of exons 6 and 7 18. The Ikk2flx/flx mice have been already used to evaluate the function of IKK2 in T-cell development, homeostasis and function 19. The double mutant mice (LckCre-Cyldflx9/flx9-Ikk2flx/flx) were viable, fertile and showed no obvious abnormalities.

All corresponding isotypes were purchased from BD Bioscience (Heidelberg, Germany). For intracellular staining, the BD Cytofix/Cytoperm Kit (BD Bioscience) was used. For stimulation, we used anti-CD3

mAb from Beckman Coulter, rh-IL-2 from Stratmann (Hamburg, Germany), rh-GM-CSF and rh-IL-4 from R&D Systems, rh-IL-10, rh-IL-15, and rh-TGF-β from Peprotech-Tebu (Frankfurt, Germany). For cell Buparlisib nmr culture assays, complete medium (Rxx10) consisting of RPMI 1640 supplemented with 10% v/v ΔFCS, 100 IU/mL penicillin, 100 μg/mL streptomycin, and L-glutamine (2 mmol/L) was used. All cells were cultured in this medium and incubated in a humidified atmosphere at 37°C with 5% CO2. With the permission and supervision of the Local Ethical Committee, human peripheral blood mononuclear cells (PBMCs) were purified from heparinized venous whole blood from healthy donors by density gradient separation using Biocoll according to manufacturer’s guidelines (Biochrom AG). NK cells were purified from PBMCs using NK Cell Isolation Kit from Miltenyi Biotec (Bergisch Gladbach, Germany)

according FDA approved Drug Library price to the manufacturer’s instructions to deplete non-NK cells. The purity of NK cells was confirmed by flow cytometry, and contamination with T cells and B cells was always below 1%. CD4+CD25− T cells were isolated from PBMCs using Regulatory T Cell Separation Kit from Miltenyi Biotec according to the manufacturer’s instructions. CD4+CD25− T cells were used for generation of autologous responder T cells. CD4+CD25+ nTreg very cells were separated from PBMCs using the CD4+CD25+ regulatory T cell Isolation Kit from Miltenyi Biotec according to manufacturer’s instruction. To this end, lymphocytes were depleted of non-CD4+ T cells and positively selected for CD4+CD25+ T cells. Monocytes within PBMCs were separated from lymphocytes by plastic adherence. Monocytes were differentiated into immature DCs (iDCs) within 7 days in the presence of IL-4 and GM-CSF (500 IU/mL each with

medium change on days 3 and 5). PCI-13 cells, a HLA-A2+ human squamous cell carcinoma of the head and neck (HNSCC), were used to generate tumor iTreg cells. PCI-13 was a kind gift from the Whiteside Laboratory at the University of Pittsburgh Cancer Institute 43. Colo699 (human lung adenocarcinoma cell line) cells were used as target cells in cytotoxicity assays. Transduction of cells with an adenovirus encoding the human NKG2D-ligand MICA (Ad-MICA) was performed earlier in our laboratory 44. The human erythroleukemia line K562 was obtained from DSMZ (Braunschweig). All tumor cell lines were routinely tested and confirmed to be mycoplasma free. CD4+CD25− T cells were co-cultured with autologous iDCs and mitomycin C treated (0.5  mg/mL, for 30 min) PCI-13 cells at a ratio of 10:1:1 with 106 T cells/mL in Rxx10 medium for 10 days.

Theissen, 2007). Although both theories explain existing behavioral data, they imply that speech perception is well developed in children at this age, and that top-down factors impede it (Werker & Curtin, 2005). However, it is possible that bottom-up speech perception factors, that is, perceptual abilities

that are relevant for speech but not completely developed, may contribute to this failure. Although discrimination tasks indicate that some category boundaries are established by 1 year (e.g., Werker & Tees, 1984), there is also abundant evidence that children refine their phoneme categories well into the school years (Nittrouer, 2002; Ohde & Haley, 1997; Slawinski & Fitzgerald, 1998). Tamoxifen cell line Thus, it is possible that 14-month-olds’ phonetic categories are only partially developed, and the

existing categories, while sufficient to succeed at discrimination tasks, may provide a weak platform for word learning. Rost and McMurray (2009) assessed this by examining the role of acoustic variability in learning phonologically similar words. We hypothesized that if speech categories were still developing, the small set of acoustic exemplars provided in most studies (Stager & Werker, 1997; Werker et al., 1998, 2002) might leave ambiguity about the structure of the phonetic category. Variability could provide more structure to the phonetic category, supporting word learning. Anidulafungin (LY303366) Similar effects of variability on category learning PF-01367338 concentration have been observed in both visual categorization (Oakes, Coppage, & Dingel, 1997; Quinn, Eimas, & Rosenkrantz, 1993) and in the acquisition of phonetic categories in a second language (Lively,

Logan, & Pisoni, 1993), suggesting that this simple manipulation may be an important way to support categories that are not yet fully developed. Fourteen-month-olds were tested in the switch task (Werker et al., 1998) by habituating them to two novel objects paired with two novel, phonologically similar, words (/buk/ and /puk/, both rhyme with “luke”1). Infants were then tested on a same trial, where the word–object pairing was consistent with habituation, and a switch trial, where the word–object pairing was opposite of what it had been in habituation. If infants internalized the word–object mapping, they should dishabituate on the switch trials. Experiment 1 replicated prior work: infants hearing a small set of exemplars failed to notice the switch. However, Experiment 2 employed multiple exemplars of the words spoken by 18 speakers; infants hearing variable exemplars correctly acquired the two phonologically similar words. At face value, successful learning in the multitalker condition is surprising.

In December 2011, he presented with several month history of multiple episodes of epistaxis and sensation of left nasal fullness. Examination revealed a left intranasal mass which was excised. It is unclear where the patient acquired the MH, given it is reported across all continents,[2] however it was noted in the preceding 12 months he had Akt inhibitor travelled to South-East Asia (Thailand and Vietnam) and to Queensland (Mackay and Whitsundays).

He continues to work in administration in the seafood industry and occasionally visits fish factories in industrial estates and cities worldwide. Tissue histology from the intra nasal lesion showed acid fast bacilli, which was initially thought to be Mycobacterium leprae and initial empirical antibiotic treatment for consisted of rifampicin, dapsone and clofazimine. One month later an analysis of the Mycobacterium DNA with polymerase chain reaction (PCR) identified the organism as MH and his Nutlin-3a ic50 antibiotic regimen was altered to clarithromycin, ciprofloxacin, rifamipicin and dapsone. Dapsone was continued as a treatment for both the Mycobacterium and as Pneumocystis

jiroveci prophylaxis. At the same time, prednisolone dose was increased from 5 to 50 mg daily, to suppress reactive inflammation at the site of infection. Despite this, he experienced increased nasal pain which gradually resolved over the subsequent two weeks. The introduction of rifampicin necessitated close monitoring of tacrolimus trough levels. He required an increase in his tacrolimus dose from 3 mg twice daily to 8 mg twice daily, in order to maintain trough levels between 4–6 μmol/L. After 13 months of antimicrobial therapy, he complained of fatigue and exertional dyspnoea and was noted to be pancytopaenic (haemoglobin 87 g/L, white cell count 3.6 × 109/L and platelets 133 × 109/L). ‘Blister and bite’ cells seen on blood film implicated dapsone as the likely cause although notably he was not glucose-6-phosphate Sulfite dehydrogenase dehydrogenase deficient. Serial computed tomography (CT) showed size reduction of bilateral

chronic mucous retention cysts (Fig. 1). Given the apparent resolution of the intranasal masses on CT, his antibiotic therapy was stopped and haematological parameters normalised. He had completed 13 months of treatment. Two weeks after stopping antibiotics, the patient noted mild hand swelling and bilateral wrist pain. Two months later he complained of bilateral migratory polyarthralgia of his hands, was noted to have painful swollen fingers, one episode left iritis with painful red eye and left achilles tendonitis. He was trialled on a two-week course of 25 mg prednisolone for possible inflammatory arthritis with no improvement. HLA B27 and rheumatoid factor were negative. Over the ensuing two months, he developed multiple, painless, non-discharging erythematous nodules over his right fingers, left elbow and left lateral malleolus (Fig. 2).

We describe a recently encountered case of tumor lysis syndrome detected during detailed examination of lung cancer with liver metastasis. Methods & Results: The patient was a 79-year-old male. He was being managed at the Department of Nephrology of our hospital because of chronic kidney disease (Cr: 2.5 mg/dl). Early in April of XXXX, he developed pain involving the right hypochondrial region and anorexia. Because of intense malaise, he visited the outpatient critical care unit of our hospital on April 6. At that time, blood tests revealed marked elevation of

hepatobiliary enzymes, and CT scan disclosed a tumorous lesion approximately 13 cm in size in the right lobe of the liver. He was thus hospitalized to undergo detailed examination. Liver biopsy was performed on the 11th hospital day. Around April 15, his urine volume began to decrease, and blood tests the following day revealed elevation of BUN (60.0 mg/dl) and Cre (3.67 mg/dl), accompanied NVP-BGJ398 by uric acid elevation (22.2 mg/dl). Renal function did not improve despite fluid therapy. Hemodialysis was thus started on April 18. Thereafter, the uric acid level decreased but urine volume showed no improvement and his general condition gradually deteriorated. The biopsy results allowed a diagnosis of small-cell carcinoma, suggesting that the nodular shadow noted in the right lung represented the primary Dimethyl sulfoxide tumor. Treatment

was judged to be difficult in view of his general condition, and the patient was followed without active treatment. He died on April 23. Conclusion: We thus encountered a case of tumor lysis syndrome probably arising from autolysis of small-cell lung carcinoma and an associated metastatic hepatic lesion.

However, the prognostic value of platelet size for mortality has not been studied in patients with acute kidney injury (AKI). Methods: A total of 349 patients who received continuous renal replacement therapy (CRRT) for AKI between August 2009 and October 2011 were divided into two groups based on the median mean platelet volume (MPV) at the time of CRRT initiation.

For the past 20 years, to study human IBD mechanistically, a number of murine models of colitis have been developed. These models are indispensable tools to decipher underlying mechanisms of IBD pathogenesis as well as to evaluate

a number of potential therapeutics. Among various chemically induced colitis models, the dextran sulfate sodium (DSS)-induced colitis model is widely used because of its simplicity and many similarities with human ulcerative colitis. This model has both advantages and disadvantages that must be considered when employed. This Nutlin-3a chemical structure protocol describes the DSS-induced colitis model, focusing on details and factors that could affect DSS-induced pathology. Curr. Protoc.

“Immunoglobulin (Ig) therapy is the mainstay for treatment

in the majority of primary immune deficiencies. While B cell defects are the predominant conditions in man, other diseases in which T cell dysfunction is severe also require antibody replacement. In many medical practices the phenotypic overlap between immune deficiency and symptoms of asthma leads to both missed opportunities for diagnosing immune defects and inappropriate Ig treatment of asthmatic patients with p38 protein kinase normal B cell function. As steroid therapy can lower serum IgG levels, this finding alone is an insufficient indicator for Ig replacement. In the past 3 decades, there has a gradual increase in recommended and commonly used doses of parenteral immune globulin, often based on both IgG trough levels and clinical responses. Special attention to Ig doses is needed for growing children, in cases of weight loss or gain, pregnancy and for subjects in

whom more Mannose-binding protein-associated serine protease rapid consumption of Ig is likely, including febrile patients or those with gastrointestinal or lung disease. While acute bacterial infections are much less common in Ig-treated subjects, a number of reports note continued evidence of inflammatory complications. Monitoring patients over time includes, at minimum, physical examination, blood counts and chemistry screening tests and IgG trough levels, at 6–12-month intervals. Other monitoring tools include spirometry and at wider intervals with those with lung disease, carbon monoxide diffusion capacity and chest computed tomography scans. With careful selection of patients and adequate therapy, an improved quality of life is possible. In the past 3 decades, replacement immune globulin (Ig) therapy has become the standard of care in patients with primary and secondary antibody defects [1–3]. While many studies have described this advance in medical care, the increasing number of patients on this therapy, and diversity of physicians in various specialities who care for them, suggests that practical guidelines for the use of Ig may be of use. The current paper outlines an approach to achieve successful therapy with Ig in patients with primary immune defects.
