Introduction
Malaria is a parasitic disease of humans and is caused by protozoa of the genus Plasmodium. According to WHO, in 2018, an estimated 228 million cases of malaria occurred worldwide. Nineteen countries in sub-Saharan Africa1 and India carried almost 85% of the global malaria burden. An estimated 405,000 deaths occurred from malaria globally and Nearly 85% of deaths were concentrated in 20 countries in the WHO African Region and India. There were an estimated 6,737,000 malaria cases and 9,620 deaths in India in 2018. Malaria infections may cause vital organ damage and death. Severe malaria is defined by clinical or laboratory evidence of vital organ damage. The manifestations of severe malaria include: Cerebral malaria, Unarousable coma, Jaundice, Renal failure, Acidosis, Severe anaemia, Pulmonary oedema/adult respiratory distress syndrome, Hypoglycaemia, Hypotension/shock, Bleeding/disseminated intravascular coagulation, Convulsions, Haemoglobinuria, Hyperparasitaemia.1
Delay in Diagnosis and treatment leads to increase in the presentation of severe malaria cases which in turn leads to increase in morbidity and mortality. The current study was conducted to study clinical profile, complications and outcome of malaria. Exact clinical and laboratory profile is important for the early diagnosis and successful management, which is crucial for saving lives and malaria being endemic in India lack of data from this geographic area on the clinical profile, complications of malaria has prompted us to undertake this study.
Materials and Methods
A Cross-sectional, observational study done in Department of general medicine, Government General Hospital, Nizamabad in Fifty smear positive malaria patients admitted to the medical wards and intensive care units are included in the study. Study done for a period of 1 Year (1st December 2019 to 30th November 2020)
Sample size
Formula: n = zα2 * pq / d2
Where, n is the required sample size.
Z α is the standard normal deviate, which is equal to 1.96 at 95% confidence interval. p is the prevalence in that study = 68.53 (Nadkar MY et al.) 2
q = 100-p
d = allowable error
p = 68.53 (Nadkar MY et al.) 2
q = 31.47
d = Allowable error taken as 20%
n = number of samples is to be studied
n = zα2 * pq / d2
= (1.96)2* 68.53* 31.47 / (13.706)2
= 8284.94/187.85
=44.10= 44.10 + 4.41
= 48.51 = Rounded to 50
Inclusion criteria
Patients of either gender, above 18 years of age and below 60 years of age, diagnosed with malaria on peripheral smear.
Exclusion criteria
Patients below the age of 18 years and above the age of 60 years, Patients diagnosed with chronic liver, kidney/CNS disease.
Methodology
After obtaining written informed consent, a detailed history and clinical examination was done to note complications and outcome.
The following laboratory investigations for hematological parameters were done: Hemoglobin estimation, Total and Differential Leucocyte count, Total Platelet count. In severe cases coagulation parameters like Bleeding time, whole blood Clotting time, Prothrombin time were done. Thick and Thin Blood smear with Giemsa staining were done for confirmation of Malaria.
Biochemical investigations like blood Sugar, serum Bilirubin, Aspartate and Alanine aminotransferase, blood Urea, serum Creatinine and Electrolytes were carried out. In patients with respiratory distress and renal failure, X-ray Chest and Arterial Blood Gas Analysis were done. HBsAg, Widal test, Dengue serology and Leptospiral antibodies test were done.
All patients were treated with intravenous/oral Artemisinin-based combination therapy. Other supportive measures in the form of antibiotics, anticonvulsants, antiemetics, blood transfusion inotropic support and fluids, dialysis and ventilator support as and when required.
Statistical analysis
Data entry was done using M.S. Excel and statistically analyzed using Statistical package for social sciences (SPSS Version 21) for M.S Windows. Descriptive statistical analysis was carried out to explore the distribution of several categorical and quantitative variables. Categorical variables were summarized with n (%). All results are presented in tabular form and are also shown graphically using bar diagram or pie diagram as appropriate.

Discussion
This study was conducted in the Department of General Medicine, Government General Hospital, Nizamabad. A total number of 50 smear positive malaria patients were included in the study. The study was done over a period of 12 months from 1st December 2019 to 30th November 2020.
In this study, Majority of the patients belongs to the age group of 18-30 years [36%] followed by 41-50 years [32%] and 31-40 years [32%]. It is coinciding with other authros with age groups as Aundhakar S et al. 9 38% (18-30 years), Chouhan AS et al.,10 48% (21-30 years), Shah SJ et al., 4 51% (15-30 years), Jelia S et al.,11 38% (21-30 years), Dabadghao VS et al.,3 33% (21-30 years), Devineni SB et al.,12 30% 21-30 years) and Madhu M et al., 7 70% (21-30 years). our study was comparable to all studies except Suryawanshi A et al., 13 and it can be observed that majority of subjects were in age group ranging between 21-30 years. In this study, Males constitute 62% and females constitute 38%.
Our study was comparable to other studies and it can be observed that majority of subjects were male. Our study is comparable with studies done by Kulkarni VK et al., 14 (M-65.67% ,females-34.44%) , Shah SJ et al.,4 (males-57%, females-43%), Jelia S et al., 11 (males -78%, females-22%) , Dabadghao VS et al., 3 (males -67%, females-33%), Nadkar MY et al., 15 (males -71.9%, females-28.1%), Chowta MN et al., 6 (males-72%, females-28%).
The high infectivity in males might be explained on the basis of the fact that males are more mobile and involved in outdoor activities and they also readily seek medical aid. Further, females in India are usually better clothed than males, and hence they are less exposed.

Conclusion
Malaria is still at rampant in India with debilitating morbidity and mortality. Studying the clinical profile of malaria with proper antimalarial drug treatment helps to curb down the complications of malaria. Every healthcare facility should follow national and international guidelines and form its in-hospital guidelines regarding proper antibiotic and antimalarial selection. This helps to reduce morbidity and mortality of malaria and helps in the sustained economic growth of the nation. Malaria is a completely curable disease.
