Identification and Characterization of a Nationwide Danish Adult Common Variable Immunodeficiency Cohort.

In this study, we identified all adults living in Denmark diagnosed with common variable immunodeficiency (CVID) and characterized them according to clinical presentation and EUROclass classification. Using a retrospective, cross-sectional design, possible CVID patients were identified in the Danish National Patient Register and Centers in Denmark treating patients with primary immunodeficiencies. The CVID diagnosis was verified by review of medical records. One-hundred-seventy-nine adults with CVID were identified. This corresponds to a prevalence of 1:26,000. The median age at onset of symptoms was 29 years with no sex difference. The median age at diagnosis was 40 years. Males were diagnosed earlier with a peak in the fourth decade of life, whereas females were diagnosed later with a peak in the sixth decade. The median diagnostic delay was seven years. Recurrent sinopulmonary infections were seen in 92.7% of the patients. The prevalence of non-infectious complications was similar to that of previously reported cohorts: bronchiectasis (35.8%), splenomegaly (22.4%), lymphadenopathy (26.3%), granulomatous inflammation (3.9%) and idiopathic thrombocytopenic purpura (14.5%). Non-infectious complications were strongly associated with B cell phenotype, with all having a reduced number of isotype-switched memory B cells. One-hundred-seventy (95%) were treated with immunoglobulin replacement therapy, primarily administered subcutaneously. According to international guidelines, diagnostic evaluation was inadequate in most cases. This study emphasizes the need for improved diagnostic criteria and more awareness of CVID as a differential diagnosis. Diagnosis and management of CVID patients is a challenge requiring specialists with experience in the field of PID.

[Early resuturing after abdominal wound infection under prophylactic metronidazole and ampicillin]. / Tidlig resutur efter abdominal sårinfektion under daekke af metronidazol og ampicillin.

A randomized double-blind investigation was undertaken to assess the effect of treatment with metronidazole and ampicillin in patients with subcutaneous wound infection after laparotomy and early resuture. The wounds were closed in the fourth day and the antibiotic cover lasted from one to four days. None of the patients developed signs of sepsis or new abscesses. All of the wounds healed primarily but there were slight defects in two patients. These did not require surgical treatment. It is concluded that early closure of infected wounds after laparotomy may be undertaken under metronidazole and ampicillin cover and that treatment for one day is sufficient.

Bactericidal antimicrobial cover in primary suture of perianal or pilonidal abscess. A prospective, randomized, double-blind clinical trial.

The effect of 1-day treatment vs. 4-day treatment with metronidazole and ampicillin in association with primary closure of perianal and pilonidal abscesses was evaluated in a double-blind clinical trial. The patients were randomly allocated to 1-day (group I) or 4-day (group II) antibiotic regimen. No clinical signs of sepsis appeared in any patient. Primary healing, without fistula formation was achieved in all 17 perianal abscesses in the 1-day therapy group and in 14 of 15 in the 4-day group (non-significant difference). Excision with primary suture of pilonidal abscess resulted in primary healing in 20 of 26 cases in group I and 20 of 30 in group II (non-significant difference). Healing with formation of a new sinus or secondary healing occurred in four and two cases, respectively, in the 1-day therapy group, and in two and nine of the 4-day group. One-day administration of metronidazole/ampicillin is as effective as 4-day treatment in primary closure of perianal and pilonidal abscess. The procedure appears to be safe in both groups, but more efficacious in perianal abscess.

Management of severe incisional abscesses following laparotomy. Early reclosure under cover of metronidazole and ampicillin.

Patients developing severe incisional abscesses following laparotomy were treated with incision and drainage followed by early reclosure under antibiotic cover with metronidazole and ampicillin anhydricum. Patients with subcutaneous abscesses were randomized into two groups that were treated with antibiotics for one day (n = 23) or four days (n = 27). These patients all underwent reclosure four days later. In a third group of patients (n = 14) abscesses had developed down to, but not through, the peritoneum. These patients received antibiotic treatment for four days and underwent reclosure a mean of 5 1/2 days later (range, four to eight days). No abscesses reappeared in any group and all wounds healed by first intention. Five patients healed totally, with minor defects, but there was no need for surgical intervention. We conclude that the early reclosure technique is a safe procedure under antibiotic cover with metronidazole and ampicillin. One day and four days of antibiotic treatment are equally safe in patients with subcutaneous abscesses.
