Background: The use of intrauterine contraceptive device (IUCD) generally has been known to be safe and effective but tends to have some side effects. Reproductive tract infection is one of the major complications caused by prolonged usage of an IUCD. Cervical smears have shown an increase in inflammation, inflammatory epithelial changes, or metaplastic cells among the IUCD users as compared to nonusers. There is also a predisposition to higher rate of infections such as Actinomyces, atypical squamous cells of undetermined significance, and low-grade squamous intraepithelial lesion. Aims and Objectives: The aim of this study was to study changes in cervical cytology in IUCD users and to assess the risk of epithelial cell abnormalities among IUCD users compared to nonusers. Materials and Methods: A 2-year cross-sectional study was carried out to screen Papanicolaou (Pap) smears in women of the reproductive age group who were categorized as IUCD and non-IUCD users. Results and Observations: A total of 1100 (550 + 550) Pap smears from IUCD and non-IUCD users were analyzed. Among IUCD users, 544 cases (98.90%) were adequate for reporting including 533 cases (97.98%) showing negative for intraepithelial lesion or malignancy (NILM) and 11 cases (2.02%) showing epithelial cell abnormality (ECA). In non-IUCD users, 541 cases (98.36%) were adequate for reporting. Among these, 538 cases (99.44%) showed NILM and 3 cases (0.56%) showed ECA. Conclusion: In IUCD users, the prevalence of infections and ECA is higher than non-IUCD users.

| Introduction|| |
The use of intrauterine contraceptive device (IUCD) generally has been known to be safe and effective, reliable, reversible, economic, and safe method for regulation of population but tends to have some side effects., At present, copper-T380A (Cu-T) is the most widely used IUCD in India. Reproductive tract infection is one of the major complications caused by prolonged usage of an IUCD., Several studies have demonstrated a higher prevalence of bacterial vaginosis (BV) and pelvic inflammatory disease among IUCD users in different countries.,,,
Cervical smears have shown an increase in inflammation, inflammatory epithelial changes, or metaplastic cells among the IUCD users as compared to nonusers. There is also an increased incidence of inflammation with prolonged use of Cu-T. There is also a predisposition to higher rate of infections such as Actinomyces, atypical squamous cells of undetermined significance (ASCUS), and low-grade squamous intraepithelial lesion (LSIL).
IUCD use has been shown to reduce the risk of endometrial cancer, but little is known about its association with cervical cancer. In the present study, we aimed to observe the changes in cervical cytology in IUCD users and to assess the risk of epithelial cell abnormalities among IUCD users compared to nonusers.
| Materials and Methods|| |
This hospital-based cross-sectional study design was conducted in the department of pathology, in collaboration with the department of obstetrics and gynecology, for a period of 2 years. A total of 550 women who were in the age group of 18–45 years with more than 6 months of using the IUCD were the study population, and 550 women of similar age range but nonusers of any hormonal or IUCD contraceptive method were taken as controls. Women who were using IUCD for <6 months were not included in the current study.
Relevant history, presenting complaints, and examination findings including per-speculum findings were noted before doing the procedure.
After taking informed consent from the patient, they were instructed to avoid conjugal relation 2–3 days before sample collection and not to use any vaginal douche for 24 h before subjecting to a Papanicolaou (Pap) smear examination. The cervix was made completely visible after the introduction of a cervical speculum. The cervix was sampled using an Ayre's spatula. The material was spread evenly and thinly on two clean glass slides and wet-fixed by immersing it in 95% ethanol for a minimum of 15 min. The smears were stained with Pap stain followed by mounting with distyrene plasticizer xylene and coverslip of suitable size and reported according to The Bethesda Classification 2014.
| Results and Observations|| |
A total of 550 Pap smear More Detailss of IUCD users were screened and compared the result with the result of 550 Pap smears which were taken from female non-IUCD users of the reproductive age group. The data were complied, tabulated, and analyzed statistically.
Among 550 Pap smears of IUCD users, 544 cases (98.90%) were adequate and 6 cases (1.10%) were inadequate for reporting. On the other hand, among 550 Pap smears studied in non-IUCD users, 541 cases (98.36%) were adequate and 9 cases (1.64%) were inadequate for reporting.
In IUCD users, 533 cases (97.98%) showed negative for intraepithelial lesion or malignancy (NILM) and 11 cases (2.02%) had epithelial cell abnormality (ECA). Among ECA, 4 cases (33.36%) of ASCUS, 4 cases (33.36%) of LSIL, 2 cases (18.19%) of high-grade squamous intraepithelial lesion (HSIL), and 1 case (9.09%) of squamous cell carcinoma (SCC) of the cervix were observed. Among NILM cases, 28 cases (5.26%) showed normal findings while 402 cases (75.42%) were reactive cellular changes associated with inflammation, 69 cases (12.94%) showed BV, 22 cases (4.13%) were infection with Candida species, 9 cases (1.69%) of Trichomonas vaginalis, and 3 cases (0.56%) of Actinomyces. Different types of Pap smear findings in non-IUCD users were also compared [Table 1], [Table 2] and [Figure 1], [Figure 2].

The present study showed that both infections and ECA were more commonly encountered in IUCD users as compared with non-IUCD users; P values were 0.0314 and <0.0001, respectively, which are statistically significant (P < 0.05).
Age distribution of the IUCD users in the study group showed that the maximum number of patients belonged to the age group of 21–30 years (268 cases, 49.26%), followed by 31–40 years (216 cases, 39.71%), >40 years (47 cases, 8.64%), and the least number of cases was in the group <20 years (13 cases, 2.39%). The youngest patient among the IUCD users was 19 years old and the eldest was 45 years old with a mean age of 31.45 years and median age of 30 years. Among non-IUCD users, the maximum number of patients belonged to the age group of 31–40 years (319 cases, 58.97%), followed by 21–30 years (198 cases, 36.60%), >40 years (13 cases, 2.40%), and the least number of cases was in the group <20 years (11 cases, 2.03%). The youngest age of the non-IUCD users screened was 19 years and the eldest was 44 years with a mean age of 31.47 years and median age of 32 years [Table 3].

The parity in the IUCD users ranges from P1+0 to P6+0. Maximum patients were in the P2+0 group (228 cases, 41.91%), followed by P1+0 (112 cases, 20.59%), P3+0 (108 cases, 19.85%), P4+0 (83 cases, 15.26%), P5+0 (2 cases, 0.37%), and P6+0 (11 cases, 2.02%). Among 533 NILM cases in IUCD users, majority of the cases were in P2+0 group (230 cases, 24.53%). On the other hand, in non-IUCD users, maximum patients were in P2+0 group (199 cases, 36.78%) which was followed by P3+0 (151 cases, 27.91%), P1+0 (118 cases, 21.81%), P4+0 (62 cases, 11.46%), P5+0 group (9 case, 1.67%), and P6+0 group (2 cases, 0.37%) [Table 4].

| Discussion|| |
The Pap smear is a screening test that can be carried out readily during gynecological examination. It should be conducted once a year in women of the reproductive age. Although the Pap smear was developed for cervical cancer screening, it is obvious that it sheds light on nonneoplastic pathologies, as well.
In our study, 98.90% of cases were adequate and 1.10% were inadequate for reporting. This finding was comparable with the study conducted by Rahime et al. which showed that 93% Pap smears of IUCD users were adequate for reporting while 7% were inadequate.
In our study, 97.98% of the IUCD users were diagnosed cytologically as NILM and only 2.02% were diagnosed as ECA. Similar findings were seen in the studies conducted by Nayak et al. which showed that 98.6% of cases were NILM and 1.4% of cases were ECA.
In the present study, among ECA detected in IUCD users, ASCUS and LSIL comprised most 33.36% each, followed by HSIL (18.19%) and SCC of the cervix (9.09%), which was similar to a study done by Nayak et al. which revealed that 57.14% of ECA were of ASCUS. However, a study by Lekovic et al. showed that 5.9% of cases had ECA, and among these, 98% were of ASCUS.
Observation of high ASCUS and LSIL rate in the study group might reflect reactive cellular alterations that are derived from inflammation and vaginal flora alterations.
The copper in the device progressively diminishes, leaving a minimal amount of the metal on the device at the end of 3 years. However, it may be possible that constant release of the copper from the device in the first 3 years of insertion in some way initiates cellular changes in the cervical epithelium that promotes the occurrence of dysplasia at a later date.
Among NILM group in IUCD users, we found that 5.26% showed normal findings, 75.42% showed benign reactive changes associated with inflammation, 12.94% of BV, 4.13% of Candida species, 1.69% of T. vaginalis, and only 0.56% of Actinomyces. Findings of the present study were comparable with a study done by Rahime et al. which showed 9.3% normal findings, 71% benign reactive changes associated with inflammation, 7% BV, 7.3% Candida species, 1.4% T. vaginalis, and 4% Actinomyces.
In the present study, we found that the incidence of BV in IUCD users was 12.94%, which was similar to that of a study by Shobeiri and Nazari which showed that 12% of NILM cases had BV.
We found from the present study that 4.13% of NILM cases in IUCD users showed fungal organism morphologically consistent with Candida species, which was similar to that of a study by Haltas et al. which showed that 2.81% of NILM cases were infected by Candida species. In the study by Demirezen et al., the incidence of Candida was quite high (14%).
In the study by Nasir et al., T. vaginalis was reported as the most important cause of specific infection (33.33%). However, in the present study, the incidence of T. vaginalis in IUCD users was 1.69%, which was similar to that of a study by Rahime et al. which showed that 1.4% of NILM cases had T. vaginalis.
In our study, we got only 0.56% Actinomyces cases in IUCD users, though in IUCD users, Actinomyces infection is quite common.
In the present study, parity-wise distribution of the overall IUCD users showed that the maximum number of patients belonged to the P2+0 group (41.91%), followed by P1+0 group (20.59%), P3+0 group (19.85%), and least number of cases in >P4+0 group (17.65%). A study conducted by Anant et al. also showed a similar result.
| Conclusion|| |
From the present study, we concluded that in IUCD users, the prevalence of infections and ECA is higher than non-IUCD users. Therefore, women in the reproductive age group who are taking IUCD as a contraceptive method should undergo PAP screening with follow-up whenever required.
