Calprotectin in pregnancy and pregnancy-associated diseases: a systematic review and prospective cohort study

Abstract

Purpose

Calprotectin, a marker of acute and chronic inflammation, may play a role in pregnancy-associated disorders. We aimed to summarize available clinical data on calprotectin in pregnancy and to establish normal values of calprotectin during the course of pregnancy.

Methods

We performed a systematic review of the databases PubMed and Cochrane Central Register of Controlled Trials to identify experimental and clinical evidence assessing the role of calprotectin in pregnancy. In addition, we performed a prospective cohort study assessing serum and urine calprotectin throughout pregnancy.

Results

We identified 17 studies investigating 1638 pregnant women, 151 newborns, and 99 non-pregnant controls, measuring calprotectin in different compartments. Calprotectin was present in meconium and elevated in fecal samples of pregnant women with active inflammatory bowel disease. In women with pregnancy-induced hypertension, mild and severe preeclampsia (PE), calprotectin was significantly elevated in maternal plasma and serum, but not in fetal serum, amniotic fluid, and umbilical cord blood. For the cohort study, we recruited 196 pregnant women. PE and concomitant renal disease were present in 6/196 (3%) and 11/196 (5.6%) of women, respectively. Throughout pregnancy, median serum and urine levels of calprotectin largely exceed reported concentrations of the healthy non-pregnant population, but showed no significant variations between trimesters 1–3 and post-partum. Calprotectin in serum was correlated with systolic blood pressure and in urine with leukocytes and total protein. No significant differences were found in subgroup analyses of smokers vs. non-smokers, PE vs. none, and renal disease (kidney stones, reflux) vs. none.

Conclusion

Calprotectin concentrations in amnion fluid and stools serve as potential indicators of inflammatory states during pregnancy. Urinary calprotectin concentrations are continuously high during pregnancy and show no significant variations between trimesters 1–3 and post-partum.



The security of radical trachelectomy in the treatment of IA–IIA cervical carcinoma requires further evaluation: updated meta-analysis and trial sequential analysis

Abstract

Purpose

The aim of this study was to assess the security of radical trachelectomy (RT) in the treatment of IA–IIA cervical carcinoma and conducted a new survey based upon the results of previous researches.

Methods

The PMC, PubMed, Web of Science, Cochrane and EMBASE databases were retrieved to collect prospective clinical controlled trials (CCTs) published from 1984 to 2018. The oncologic outcomes were evaluated by meta-analysis, trial sequence analysis (TSA) and statistical analysis.

Results

Five prospective CCTs were collected in this study. The recurrence rate and mortality of RT was similar to that of radical hysterectomy (RH), which was consistent with the oncologic outcomes of meta-analysis and TSA. Patients with tumors 2–4 cm in diameter were more likely to receive RH, which may be a potential factor in the higher rate of adjuvant chemotherapy in the this group, and RH was significantly associated with the risk of intraoperative blood transfusion. It is notable that considerable negative margin was achieved by radical abdominal trachelectomy (RAT), and the clinical effect of RAT was slightly better than that of radical vaginal trachelectomy (RVT). However, the TSA results showed that the cumulative cases were not up to the required sample size to obtain the true negative or positive results.

Conclusions

It is safe and effective for early-stage patients with cervical cancer whose lesions are less than 2 cm to receive RVT. For those patients with lesions 2–4 cm who desire fertility preservation and without any evidence of infertility, RAT can be a feasible alternative to RH under fully informed consent. However, more CCTs with larger sample size are still required for further validation.



A new approach to prevent ischemia/reperfusion injury in a rat model: remote ischemic conditioning

Abstract

Purpose

To evaluate the effect of remote ischemic conditioning (RIC) on ovarian ischemia/reperfusion injury in a rat model.

Methods

A total of 36 Wistar albino rats with a body weight of 220–250 g were used for this study. Right adnexal torsion was performed for 180 min, and at the end of the period, the adnex was released and the abdomen was reclosed for 180 min for reperfusion. Torsion and detorsion procedures were applied to all rats except group 1 (sham, control). The right lower extremity was tied to perform remote tissue ischemia in groups 3, 4, 5, and 6. The goal of the procedure, which was purplish discoloration and pulselessness of the extremity, was maintained. After 5 min of ischemia, reperfusion was achieved for 5 min. Repeating this procedure 3 times was defined as hypoxia attacks (RIC). Retrieved ovaries were examined for tissue injury with biochemical, histopathologic, and immunohistochemical analysis.

Results

Unlike the control group, vascular congestion, hemorrhage, edema, and inflammatory cell infiltration were observed in group 2 (only I/R [ischemia/reperfusion]). In groups 3 (I/R + RIC), 4 (I/R + RIC), 5 (I/R + RIC), and 6 (I/R + RIC), edema and inflammatory cell infiltration were not observed. However, vascular congestion and hemorrhage that were detected in these groups were higher than in group 1 (Control) and less than in group 2 (I/R). The Caspase-3 Index was found to be increased in all groups compared to group 1 (P < .001). However, the increase in the RIC-performed groups was significantly less than in group 2. The apoptotic index, which was determined by the TUNEL, was also found to be increased in all groups compared to group 1 (P < .001). When the comparison was made in relation to group 2, the decrease of AI in RIC-performed groups was statistically significant, except the decrease in group 6 (P = .29).

Conclusions

It is not clinically conceivable to prepare the tissue for pre-ischemia in ovarian torsion. However, the RIC application, which will be initiated if torsion is suspected when arrangements are made for surgery, might be a simple, effective, and inexpensive approach to prevent I/R injury in the clinic.



Efficacy of pegylated liposomal doxorubicin maintenance therapy in platinum-sensitive recurrent epithelial ovarian cancer: a retrospective study

Abstract

Objective

To examine the effectiveness of pegylated liposomal doxorubicin (PLD) maintenance therapy (intravenous administration at dose 40 mg/m2 on day 1, repeated every 4 weeks) after first-line salvage chemotherapy for platinum-sensitive recurrent epithelial ovarian cancer.

Methods

This retrospective cohort study examined women with a first recurrence of platinum-sensitive epithelial ovarian cancer diagnosed between 2005 and 2015. Eligible cases had PLD maintenance following the first-line salvage chemotherapy (n = 28). Outcomes of interest included adverse events related to PLD maintenance therapy and survival outcome after the first recurrence.

Results

The median number of PLD maintenance cycles was 7.5 (range 2–26), and 11 (40%) women received ≥ 12 cycles. The median cumulative dose of PLD was 432.5 mg/m2 (range 120–1200 mg/m2). No women developed cardiotoxicity or secondary malignancies. There were 16 (57%) women who developed any grade of adverse events, including 3 (11%) women who developed grade 3 adverse events. There were no grade 4 adverse events. The most common adverse event was mucositis (n = 7, 25%). Dose reduction due to adverse events occurred in 14 (50%) women including 3 (11%) women with discontinuation due to toxicity. Median progression-free survival and overall survival after the initiation of PLD maintenance was 14.5 months (2-year rate 21.1%) and 51.2 months (5-year rate 43.4%), respectively.

Conclusion

Our study suggests that PLD maintenance therapy for platinum-sensitive recurrent ovarian cancer is relatively well tolerated with the use of dose reduction to manage toxicity. Our study suggests that PLD maintenance therapy may be effective for women with platinum-sensitive recurrent epithelial ovarian cancer.



Current practice and physicians' opinion about preoperative hair removal as a part of ERAS pathway implementation in gynecology and gynecology–oncology: a NOGGO-AGO survey of 148 gynecological departments in Germany

Abstract

Purpose

To gather standardized information about current practices and doctors' opinions on preoperative hair removal (PHR) from the surgical site and to evaluate the extent of PHR as one of the elements of enhanced recovery after surgery (ERAS) pathways that is established in the clinical routine in gynecology and gynecology–oncology departments in Germany.

Methods

We performed a nationwide survey among 638 primary, secondary and tertiary health care gynecological departments in Germany. Data were obtained by sending a multiple-choice questionnaire about preoperative management of hair removal. The authors also evaluated the awareness of doctors regarding PHR as well as the method and time frames of PHR. The results were compared to the existing standard of procedure (SOP) and guidelines.

Results

148 units (23.2%) took part in the survey; participants in the survey were mostly chief physicians in 47.3% of the cases. Half (50.7%) of all the responses came from certified gynecological cancer centers. A SOP regarding PHR was reported as present in 113 clinics (76.4%). 83.8% of all units are performing PHR for midline laparotomy, 52.7% in laparoscopic operations, and 45.3% in vaginal operations. 48% used a clipper, while 43.2% utilized a single-use razor. 56.1% shaved instantly before the operation, whereas 35.8% did it the day before and earlier. 40.3% of chief physicians believe that PHR causes more surgical site infections (SSI) compared to only 11.5% of junior doctors.

Conclusion

PHR in gynecological departments in Germany is performed very heterogeneously and SOPs are often not based on guidelines and ERAS principles. Around one-third of the German gynecological clinics keep strictly to the guidelines. The awareness on PHR and SSI among junior doctors is very low.
