OBJECTIVETo explore the clinical manifestation, immune abnormality and outcome of disseminated Bacille Calmette-Guérin (BCG) infection in children.

METHODThe clinical data of 18 children with disseminated BCG infection seen from January 2000 to December 2007 were analyzed retrospectively.

RESULTThirteen of the children were male among 18 patients. Disseminated infection first appeared in armpit lymph nodes ipsilateral to the vaccination site, then spread to lungs in 15, lymphnodes of mediastinum or abdominal cavity in 18, skin and soft tissues in 5, skeletons in 4, liver in 4, spleen in 8, kidney, adrenal gland or meninges in 3. Twelve children were diagnosed to have primary immunodeficiency; 3 had severe combined immunodeficiency (SCID); 7 had chronic granulomatous disease (CGD), 2 had IL-12/IFN-gamma passageway deficiency. Eleven of the 18 patients died, and the remaining 7 patients were followed up from 1 to 9 years and are alive at present, but presented recurrent skin and bone tuberculosis in 4 and recurrent other infection in 3.

CONCLUSIONMost Children with disseminated BCG infection had primary immunodeficiency. CGD and IL-12/IFN-gamma passageway deficiency accounted for considerable proportion, so special immune function should be detected in these patients. The prognosis was poor. The type of the immunodeficiency diseases should be identified in early stage and the specific immune treatment should be given to the patients.

OBJECTIVE: To investigate the efficacy and safety of polysaccharide nucleic acid-fraction (BCG-PSN) in the treatment of vasomotor rhinitis. METHOD: Sixty patients were randomly divided into BCG-PSN group (n = 30) and control group (n = 30). The patients in BCG-PSN group were administered with BCG-PSN 1.0 mg twice a week for two months, and intranasal azelastine was used if needed. The patients in control group were administered with intranasal azelastine solely twice a day, which could be decreased with the symptom relief. Follow-up was 6 months. Symptom and medication scores were recorded. Side effects were registered. RESULT: The symptom and medication scores of BCG-PSN group were significantly lower than that of control group (P < 0.01) after BCG-PSN treatment. There was no significant difference in symptom score between the two groups at 6 months after BCG-PSN treatment (P > 0.05), while the medication score of BCG-PSN group was still much lower than that of control group (P < 0.01). No serious adverse events were reported in BCG-PSN group except for local pain on the injection place in one patient. CONCLUSION BCG-PSN is effective and safe in the treatment of vasomotor rhinitis.

Bacillus Calmette-Guérin (BCG) is a live vaccine and has the potential to cause local disease and systemic dissemination in immunocompromised hosts, including infants who are infected with human immunodeficiency virus (HIV) through vertical transmission, and patients with primary immunodeficiencies (PID) such as severe combined immunodeficiency (SCID), chronic granulomatous disease (CGD), hyper-IgM syndrome, and defects of the IL12- IFNγ axis (Mendelian susceptibility to mycobacterial diseases, MSMD). Disseminated BCG is extremely difficult to treat. The chance of complete eradication is low unless functional immune response is restored by haematopoietic stem cell transplant. Prolonged use of anti-mycobacterial drugs often causes organ toxicities and drug resistance. Inflammatory complications which develop upon immunoreconstitution post-transplant may necessitate immunosuppressive treatment, which adversely affect immune recovery and increases risks of opportunistic infections. Multiple BCG reactivations can occur in patients with CGD and MSMD, and BCG can remain latent until reactivations take place in adulthood and manifest as disease. It is important for neonatologists, general practitioners, primary care clinicians and nurses working in maternal and child care centres to be aware of BCG-related complications, which may be the first sign of an underlying immunodeficiency. As neonatal BCG is included in standard vaccination schedule in many countries, it is a challenge to identify and avoid administration of BCG to infants who potentially have PIDs. Deferring BCG vaccination is recently advocated to protect highly vulnerable populations, but the appropriate strategy is yet to be determined. Newborn screening for SCID offers a potential to avoid this complication, if an integrated system of screening and vaccination can be organised.

The bacilli Calmette-Guerin (BCG) Tokyo-172 strain was considered to exhibit good protective efficacy with a low rate of unfavorable side effects. However, we describe a rare case of BCG osteomyelitis developed in an immunocompetent host who was given with BCG Tokyo-172 vaccine on the left upper arm by multipuncture method. A 9-month-old girl presented with progressive inability to move her right elbow and had radiographic evidence of septic elbow combined with osteomyelitis of right distal humerus. A biopsy from the site revealed chronic caseating granulomatous inflammation, positive for BCG Tokyo-172 strain on the multiplex polymerase chain reaction. The child had to undergo second surgical debridements and oral antituberculosis chemotherapy. There were no sequelae after 2 yr of follow-up. This complication, although uncommon, should be considered in the appropriate clinical setting.

OBJECTIVEInterleukin-12 receptor beta1 (IL-12 Rbeta1) deficiency is a rare primary immunodeficiency (PID) characterized by selective susceptibility to weakly virulent organisms, including Mycobacterium bovis, BCG, non-tuberculous environmental mycobacteria and non-typhoidal salmonellosis. The present study was conducted to identify the mutation type and to analyze clinical phenotype.

METHODSBased on the typical clinical manifestations and immunologic tests in this case, a varieties of PIDs were excluded and IL-12Rbeta1 deficiency was suspected. IL-12Rbeta1 chain expressed on Epstein-Barr virus-transformed lymphoblastoid B cell lines were detected by flow cytometric assay. The IL-12Rbeta1 gene sequences of the patient and her parents were analyzed by PCR-directed sequencing. The IL-12Rbeta1 gene sequences of the patient's younger brother also had been analyzed prenatally and after birth.

RESULTSAfter inoculating BCG, the patient suffered from multiple BCG infectious lymphadenitis. There was no detectable IL-12Rbeta1 on the Epstein-Barr virus-transformed lymphoblastoid B cell lines from the patient, while only mild expression on the cell line from her mother. Sequencing analysis by using sense and antisense primers separately, a novel IL-12Rbeta1 gene mutation was found in the patient which was homozygous single nucleotide substitution, a nonsense mutation with nucleotide substitution of C to T at position 853 (853C-->T) in exon 9 leading the glutamate at position 285 to the stop codon mutation (Q285X). The parents were carriers of the mutated IL-12Rbeta1 gene. But her younger brother has normal IL-12Rbeta1 gene.

CONCLUSIONThe novel IL-12Rbeta1 gene mutation is responsible for BCG infection in this case and genetic analysis is useful in carrier detection and prenatal diagnosis is feasible when the mother had a baby with identified IL-12Rbeta1 gene mutation before.

Bacillus Calmette-Guerin (BCG) has been traditionally used as a vaccine against tuberculosis. Further, intravesical administration of BCG has been shown to be effective in treating bladder cancer. Although BCG contains a live attenuated strain of Mycobacterium bovis, complications such as M. bovis BCG infection caused by BCG administration are extremely rare. Here, we report a case of BCG infection occurring after intravesical BCG therapy. A 67-yr-old man presented with azotemia and weight loss. He had been diagnosed with bladder cancer 4 yr back, and had undergone transurethral resection of the bladder tumor and intravesical BCG (Tice strain) therapy at that time. An acid-fast bacterial strain was isolated from his urine sample. We did not detect Mycobacterium tuberculosis protein 64 (MPT-64) antigen in the isolates obtained from his sample, and multiplex PCR and PCR-reverse blot hybridization assay indicated that the isolate was a member of the M. tuberculosis complex, but was not M. tuberculosis. Finally, sequence analysis of 16S ribosomal RNA and DNA gyrase, subunit B (gyrB) suggested that the organism was M. bovis or M. bovis BCG. Although we could not confirm that M. bovis BCG was the causative agent, the results of the 3 molecular methods and the MPT-64 antigen assay suggest this finding. This is an important finding, especially because M. bovis BCG cannot be identified using common commercial molecular genetics tools.
