Prophylactic therapeutic plasma exchange in pregnant woman with Familial Chylomicronemia Syndrome - A case report.

CONTEXT: Familial Chylomicronemia Syndrome (FCS) is an inherited disease where lack of lipoprotein lipase results in severe hypertriglyceridemia that frequently leads to recurrent acute pancreatitis. Pregnancy in patients with familial chylomicronemia syndrome (FCS) post a risk for mother and baby with potential complications (pancreatitis, miscarriage and death). Therapeutic approach includes strict dietary measures and plasma exchange. Despite the development of new drugs for FCS, their safety in pregnancy has not yet been confirmed. CASE DESCRIPTION: We present a case of a young, pregnant female with FCS who had miscarriage in the past during one episode of acute pancreatitis. Due to the inability to achieve lower TG levels with current therapy, from 27-th week of pregnancy we have started prophylactic therapeutic plasma exchange (two times per week). Patient was followed up until the delivery of a healthy baby boy and did not experience an episode of acute pancreatitis. CONCLUSIONS: With adequate supervision and monitoring therapeutic plasma exchange represents a safe approach in pregnant women with FCS in order to reduce TGs and prevent pancreatitis. Therefore, we prevented potential complications for both mother and child.

The effect of standard-dose wintertime vitamin D supplementation on influenza infection in immunized nursing home elderly residents.

AIM: To investigate whether three-month oral vitamin D supplementation (800 IU in drops) reduces the risk of influenza infection in elderly nursing home residents vaccinated against influenza. METHODS: This cross-sectional observational study enrolled 97 participants (73.2% women) who received one dose of seasonal trivalent 2016-2017 influenza vaccine. The patients were randomized into an experimental group, which received vitamin D supplementation for three months starting on the day of vaccination, and a control group, which did not receive vitamin D supplementation. The primary outcome was the number of influenza infections laboratory-confirmed using a rapid point-of-care test based on nasal swabs collected during vitamin D supplementation. The secondary outcome was serum 25-hydroxyvitamin D level at the end of the study. RESULTS: The mean age ±standard deviation was 78.5± 8.8 years. All participants had vitamin D deficiency at baseline. Twenty-three participants who developed signs of respiratory infections during the study were tested for influenza virus. Although the number of influenza-positive participants was lower in the group receiving vitamin D supplementation as compared with the control group (5 vs 12), this difference was not significant. Vitamin D supplementation failed to increase 25(OH)D levels after three months of supplementation. CONCLUSION: Elderly nursing home residents in Zagreb County have a significant vitamin D deficiency. The recommended national supplementation of 800 IU daily failed to lead to vitamin D sufficiency and did not reduce the risk of influenza infection among the vaccinated elderly.

Acute pancreatitis after ocrelizumab treatment for relapsing remitting multiple sclerosis.

Ocrelizumab is an anti-CD20 monoclonal antibody used in the treatment of relapsing remitting and primary progressive multiple sclerosis. The main side effects are infusion-related with long term administration raising the risk of infections. During randomized controlled trials five cases of pancreatitis have been reported. We present a case of a patient with no risk factors for pancreatitis who after administration developed acute pancreatitis albeit with a good recovery.

Comparison of clinical and sewage isolates of Acinetobacter baumannii from two long-term care facilities in Zagreb; mechanisms and routes of spread.

In the previous studies OXA-23-like and OXA-24-like ß-lactamase were reported among Acinetobacter baumannii in both hospitals and long-term care facilities (LTCF) in Croatia. The aim of this study was to analyze clinical and sewage A. baumannii isolates from two nursing homes in Zagreb, with regard to antibiotic susceptibility and resistance mechanisms, to determine the route of spread of carbapenem-resistant isolates. Nine clinical isolates were collected from February to May 2017 whereas in April 2017, ten A. baumannii isolates were collected from sewage of two nursing homes in Zagreb. Antibiotics susceptibility was determined by broth microdilution method. The presence of carbapenemase and extended spectrum ß-lactamases (ESBL) encoding genes was explored by PCR. Conjugation and transformation experiments were performed as previously described. Genotyping was performed by SG determination, PFGE and MLST. Seven clinical isolates were positive for blaOXA24-like whereas two clinical and environmental carbapenem-resistant isolates, respectively, were found to possess blaOXA-23-like genes. Attempts to transfer imipenem resistance were unsuccessful indicating chromosomal location of blaOXA-23 gene. All carbapenem-resistant isolates belonged to SG- 1 (IC-2) whereas the rest of the isolates susceptible to carbapenems were allocated to SG- 2 (IC-1). PFGE analysis revealed low degree of genetic variability within both IC- I and IC- II. MLST corroborated that two environmental OXA-23 isolates belong to the ST-195. This study showed dissemination of OXA-23 producing A. baumannii from the nursing home into the urban sewage. Disinfection of nursing home sewage should be recommended in order to prevent the spread of resistance genes into the community sewage.
