METHODS: Five centers participated in this retrospective study and completed a data form, which included general patients' information, clinical and laboratory data.
RESULTS: Among 236 CID patients, 127 were BCG vaccinated. 41.9% of patients with family history of CID and 17.1% who were diagnosed by screening were BCG vaccinated. Twenty-three patients (18.1%) developed BCG-VACs. The median age of VACs was 6 months and the median time from vaccination to complications was 6 months. The highest rate of BCG-VACs was recorded in patients receiving the Russian BCG strain compared to the Tokyo and Danish strains. Univariate analysis of T-lymphocyte subsets showed increased odds of BCG complications in patients with CD3+, CD4+, and CD8+ counts of ≤250 cells/µL. Only CD8 + count ≤250 cells/µL had increased such odds on multivariate analysis. VACs were disseminated in 13 and localized in 10 patients. Localized complication occurred earlier after vaccination (median: 4 months) compared with disseminated ones (median: 7 months). There were no significant associations between sex, administered vaccine strain, serum immunoglobulins levels, lymphocyte subsets counts, and the chance of having either localized or disseminated BCG-related complications.
COCLUSIONS: Although contraindicated, many patients with CID continue to be vaccinated with BCG. Low CD8 + count is a risk factor for BCG-related complications and localized complications occurred earlier than disseminated ones. Considerations should be undertaken by health care authorities especially in countries with high incidence of CID to implement newborn screening, delay the time of BCG vaccine administration beyond 6 months of age and to use the relatively safer strains like the Danish and Tokyo ones.
METHODS: Data collection was done retrospectively from five centers and included general patients' information, and clinical and laboratory variables. Inclusion criteria were untransplanted patients who are either dead or alive with a follow-up period ≥6 months after diagnosis.
RESULTS: Two hundred and thirty-six CID patients were reported by participating centers, of whom 111 were included in the study with a cumulative follow-up period of 278.6 years. Seventy-two patients died with the median age of death of 10.5 months. 35.1% of the patients succumbed within 6 months after the diagnosis. Having a history of Candida infections, sepsis or hepatomegaly was associated with an increased risk of early death. None of the other general or clinical variables was associated with such risk. Bivariate analysis of lymphocyte subsets showed that patients with the following counts: CD3+
METHODS: Retrospective study of 236 patients with CID from the region were enrolled from 2004 to 2022.
RESULTS: 236 patients were included with a majority being profound CID. Among patients with a family history of CID, the ages at onset and diagnosis, and the delay in diagnosis were lower compared to those with no family history of CID, but this did not affect time to transplant. HSCT was performed for 51.27% of the patients with median time from diagnosis to HSCT of 6.36 months. On multivariate analysis, patients who underwent early transplant had increased odds of having CD3 count ≤1000 cell/μl, diagnosed by screening or erythroderma.
CONCLUSION: There is a delay in diagnosis and treatment of CID in our region. Establishing newborn screening programs and HSCT units in our region are the urgent need.
