INTRODUCTION: Pregnant females are considered as a high-risk group for the prevention and control of various communicable diseases. Therefore, this research was undertaken to study the clinic-epidemiological profile and biochemical parameters of COVID-19-positive pregnant females in a tertiary care hospital. METHODS: This hospital-based retrospective study was done on COVID-19-positive pregnant females admitted during April 2020–March 2021. A total of 139 patients were included in the study. Clinical, epidemiological, hematological, and biochemical profiles were described using frequency, percentages, mean, standard deviation using Microsoft Excel software. RESULTS: The mean age of study participants was 25.36 ± 3.79 years, mean duration of pregnancy was 37.53 ± 3.31 weeks. The majority of the patients were asymptomatic (89.2%). Abdominal pain was the most common symptom (66.7%) among symptomatic. All patients were managed conservatively. CONCLUSION: The study showed the mild nature of COVID-19 among pregnant females as the majority of them pregnant were asymptomatic and few presented with mild symptoms.

Pregnant women do not have a higher risk of COVID-19 infection but are at higher risk of severe disease if infected than nonpregnant females and the risk of preterm birth is higher in babies born to COVID-19 infected females. [1] COVID-19 infection during pregnancy can lead to stillbirth and preterm birth. [2] [3] [4] Approx. two-thirds of pregnant women with COVID-19 are asymptomatic, mild cold or flu-like symptoms are the most common among symptomatics. [5] Most of the published literature related to COVID-19 and pregnancy comes from China and other developed countries. There is a paucity of studies in India. The study was done in a dedicated COVID-19 tertiary care hospital which alone caters to the entire population of the Kumaon region of Uttarakhand. The study will add to evidence about clinico-epidemiological profile of pregnant females that will help the physicians involved in patient care to take rational and timely decisions regarding the management of cases. Therefore, the research was designed to study clinic-epidemiological profile and biochemical parameters of COVID-19 positive pregnant females in a tertiary care hospital.

The study was a descriptive hospital-based retrospective study conducted among pregnant females admitted in Susheela Tiwari hospital, Haldwani during April 2020-March 2021. All COVID-19 positive pregnant females admitted in the study period were included in the study. A total of 139 patients were included in the study. The study questionnaire collected information regarding epidemiological profile, clinical features, risk factors, hematological profile, and biochemical profile of study participants. The study approval was obtained from Institution Ethics Committee, Govt. Medical College, Haldwani. The privacy and confidentiality of study participants were ensured. The data were entered and analyzed using Microsoft Excel. Frequency, percentages, mean, and standard deviation (SD) were calculated for descriptive analysis.

The study was done to study the clinical-epidemiological profile of pregnant females admitted in a tertiary care hospital. The mean age of study participants was 25.36 ± 3.79 years. Most of the patients were admitted in the third trimester (98.6%) where the mean duration of pregnancy in the study population was 37.53 ± 3.31 weeks [ Table 1 ].

As per the clinical profile, the majority of the patients were asymptomatic (89.2%). Most of the symptomatic patients presented with only one symptom (73.3%) [ Table 2 ]. Abdominal pain was the most common symptom (66.7%) followed by cough (20%), fever (13.3%), loss of smell and taste (13.3%) [ Figure 1 ].

As per the risk factors, comorbidity was present in only two (1.4%) patients (hypothyroidism-1, epilepsy-1). A total of 25.9% of them had a history of the previous operation in which lower segment cesarean section (LSCS) was the commonest (72.2%) [Table 2, Figure 2 ]. All patients were managed conservatively.

As per the hematological parameters, mean Hb was 9.96 ± 1.48 g/dL, mean platelets count was 2.06 ± 0.83 lacs, and TLC was 9032.26 ± 3604.72. Mean BT and mean CT were 3.04 ± 1.25 s and 5.28 ± 0.42 s, respectively. As per the biochemical profile, mean SGOT and SGPT were 44.08 ± 44.39 and 34.70 ± 37.55, respectively, mean s. urea was 19.49 ± 12.70, mean s. creatinine was 0.63 ± 0.24, whereas mean serum electrolytes Na and K were 137.28 ± 4.11 and 4.51 ± 0.82, respectively [ Table 3 ].

The mean hemoglobin (Hb) in our study population was 9.96 ± 1.48 gm/dL. The study done by Chen et al. [10] reported median Hb to be 11.6 gm/dL (IQR, 10.8-12.8) among the study population. The study done by Bachani et al. [11] showed mean Hb to be 10.25 ± 1.98 gm/dL among the study population.

The median platelet count in our study population was 192 (153-230) *10 9 /mm 3 . The study done by Chen et al. [10] reported median platelet count was 190 (IQR, 152-244) *10 9 /mm 3 in their study participants. The study done by Bachani et al. [11] showed median platelet count was16570 (IQR, 92500) in their study population. The study done by Breslin et al. [13] reported median platelet count was 200.5 (167.25-260.25) ) *10 9 /mm 3 in their study population.

The median total leucocyte count (TLC) in our study population was 8.7 (6.6-10.7) *10 9 /L. The study done by Yan et al. [6] reported median TLC was 7.9 (IQR, 5.9-10.6) *10 9 /L in their study participants. The study done by Chen et al. [8] showed median TLC of 7.63 (IQR, 8.6-9.65) *10 9 /L in their study participants.

[11] reported median TLC to be 9.7 (IQR, 5.3) *10 9 /L in their study participants. The study done by Breslin et al. [13] reported median TLC to be 6.65 (IQR, 5.18-7.32) *10 9 /L.

The median serum glutamic oxaloacetic transaminase (SGOT) in our study population was 32 (IQR, 21-54), whereas the median serum glutamic pyruvic transaminase (SGPT) was 22 (IQR, 12-41). The study done by Chen et al. [8] reported median SGOT to be 24 (IQR, 21.5-73.5) whereas median SGPT to be 16 (IQR, 10.5-58).

The study concludes that the majority of the patients were asymptomatic, whereas the rest presented with minor symptoms with average normal hematological and biological profiles, but still, some studies showed an increased risk of severe disease therefore, COVID-appropriate behavior and vaccination among pregnant females remain the mainstay of focus to decrease mortality and morbidity among pregnant females as well as to ensure the safety of the unborn child.

The present study highlights the clinicoepidemiological profile of COVID-19 positive pregnant females showing asymptomatic/ mild symptomatic, managed conservatively, providing add-on evidence thereby will guide the treating physician in providing evidence-based care to the patients.
